     Referring to  FIGS. 3-10 , the lifting module A comprises an elevator frame A 110  which has a lifting sliding rail A 120  affixed thereon. The lifting sliding rail A 120  is slidably assembled with a lifting sliding block A 131  and a heavy pressing sliding block A 211  respectively. The sliding directions are along the length directions of the lifting sliding rail. 
     The heavy pressing sliding block A 211  is affixed on the heavy pressing supporting plate A 212 , and a heavy pressing plate A 210  is mounted on the heavy pressing supporting plate A 212 . The lifting sliding block A 131  is affixed on one of the two lifting side plates A 130  and the two lifting side plates A 130  are respectively rotatably assembled with the first lifting shaft A 510  and the second lifting shaft A 520 . The two lifting side plates A 130  have a lifting output sliding groove A 132  respectively on the top of the end face thereof that are close to each other. 
     A second lifting belt pulley A 421  and a second lifting sub-belt pulley A 422  are affixed on the first lifting shaft A 510  and on the second lifting shaft A 520  respectively, wherein the second lifting belt pulley A 421  and the second lifting sub-belt pulley A 422  are connected through a second lifting belt A 420  to form a belt transmission mechanism.

     The first lifting belt pulley A 411  is affixed on a first lifting output shaft A 311 , and the first lifting output shaft A 311  is mounted in a first lifting motor A 310 . The first lifting motor A 310  is capable of driving the first lifting output shaft A 311  to rotate in the circumferential direction. 
     The lifting side plate A 130  with the lifting sliding block A 131  mounted thereon is further assembled and affixed with an end of a lifting belt A 220 . The other end of the lifting belt A 220  bypasses a lifting wheel A 431  to be assembled and affixed with the heavy pressing supporting plate A 212 . The lifting wheel A 431  is affixed on a second lifting output shaft A 321 , wherein the second lifting output shaft A 321  is mounted in a second lifting motor A 320  so as to allow the second lifting motor A 320  to drive the second lifting output shaft A 321  to rotate forward and backward along the circumference direction. In this embodiment, the lifting belts are embodied as chains and the lifting wheels and pulleys are embodied as sprockets, wherein the chain and the sprocket form a chain transmission structure. 
     When in use, after the banknote-receiving bucket finished banknote receiving, it has to output the tooling plate  200  thereof into the lifting output sliding groove A 132 . When the second lifting motor A 320  drives the lifting wheel A 431  to rotate circumferentially, so as to drive the lifting belt A 220  to move toward the lifting side plates A 130 , leading the lifting side plates A 130  to move down along the lifting sliding rail A 120  and leading the heavy pressing supporting plate A 212  and the heavy pressing plate A 210  move up along the lifting sliding rail. Until the lifting side plates A 130  reaches a designated position, the second lifting motor will stop. At this moment, the first lifting motor will operate, so as to drive the second lifting belt A 420  to rotate and the tooling plate  200  and the second lifting belt A 420  are pressed, so as to allow the second lifting belt to drive the banknote-receiving bucket  100  to be output from the lifting output sliding groove in order to complete the output of the banknote-receiving bucket. After the banknote-receiving bucket is output, the second lifting motor stops running, the heavy pressing plate A 210  slides down under the action of gravity, and the lifting side plate A 130  rises to the position before descending under this action force. 
     When the banknote-receiving bucket is installed in the lifting output sliding groove and needs to rise, firstly, the tooling plate  200  is loaded into the lifting output sliding groove A 132 , and then the second lifting motor rotates reversely, so that the banknote-receiving bucket  100  is driven to move up and the heavy pressing plate A 210  is driven to move down through the lifting belt until align with the height of the conveying line. At this moment, the first lifting motor reversely rotates to output the banknote-receiving bucket to the conveying line.

Namely, one of them is only responsible for rising, while the other is only responsible for descending. During the descending, the utilization of the heavy pressing plate A 210  not only achieves the automatic restoration of the lifting side plate, thereby saving energy consumption, but also allows the second lifting motor A 320  to maintain power-off at this time. Here, even the empty banknote-receiving bucket  100  is to be raised, the heavy pressing plate A 210  can also provide auxiliary force for the lifting belt, thereby reducing the energy consumption of the second motor. Of course, the present embodiment has two conveying lines, and therefore each lifting module A may need to perform the lifting-descending action at the same time. 
     Preferably, in order to position the lifting height of the lifting output sliding groove A 132 , so as to allow the lifting output sliding groove A 132  to output a banknote-receiving bucket or input the banknote-receiving bucket, the present embodiment also designs a first lifting sensor A 611  and a second lifting sensor A 612 , wherein a lifting sensing head A 620  is mounted on the lifting side plate A 130  of the lifting sliding block A 131 .

There are at least four pairs of the positioning blocking modules on each flow line according to the present embodiment, so that at least four banknote-receiving buckets can be positioned at the same time. 
     The conveying side plate B 120  has a conveying guide groove B 121  and a conveying slot B 122  arranged therein, wherein the conveying chain B 620  is mounted in the conveying slot B 122 . 
     At least two the conveying side plates B 120  are provided, wherein one end of each of the two conveying side plates B 120  is rotatably assembled with a first conveying shaft B 610  respectively, while the other end of each of the conveying side plates B 120  is rotatably assembled with a second conveying shaft B 630  respectively.

     The first conveying shaft B 610  and the conveying output shaft of the conveying motor B 510  are assembled through a coupler, wherein the conveying motor B 510  is capable of driving a first conveying shaft B 610  to circumferentially rotate forward and backward, wherein the conveying chain B 620  comprises a plurality of conveying rotating wheels B 640  arranged thereon, wherein the top of the conveying rotating wheels B 640  penetrates out of the conveying slot B 122  and enters the conveying guide groove B 121 , wherein the conveying guide groove B 121  is adapted for being buckled and slidably assembled with the tooling plate  200 , so as for preventing deviation for the conveying on the conveying line of the tooling plate. The conveying rotating wheels B 640  is attached with the tooling plate  200 , so that the rotation of the conveying chain can drive the tooling plate  200  to move synchronously. 
     Referring to  FIGS. 10-13 , the blocking device B 400  comprises a first blocking plate B 421 , a second blocking plate B 422 , and a blocking affixing block B 410 , wherein the first blocking plate B 421  and the second blocking plate B 422  are respectively affixed on the blocking affixing block B 410 . The blocking affixing block B 410  is assembled and affixed with the conveying side plate B 120 . A push rod motor B 440  is mounted between the first blocking plate B 421  and the second blocking plate B 422 . The push rod motor B 440  has a mounting protruding shaft B 441  mounted on the housing thereof. A fourth blocking pin B 464  passes through the first blocking plate B 421 , the mounting protruding shaft B 441 , and the second blocking plate B 422 , so as to affix the push rod motor B 440  between the first blocking plate B 421  and the second blocking plate B 422 . 
     The second blocking plate B 422  has a first blocking sensor B 471  and a second blocking sensor B 472  arranged thereon, wherein the first blocking sensor B 471  and the second blocking sensor B 472  are respectively configured to detect the position of the first blocking pin B 461 , so as to determine the position of the blocking wheel B 490 . 
     The telescopic shaft B 441  of the push rod motor B 440  is mounted into a blocking connection barrel B 452  with a first blocking pin B 461  penetrating the blocking connection barrel B 452  and the telescopic shaft B 441 , so as to axially assemble and affix the blocking connection barrel B 452  and the telescopic shaft B 441 . 
     The blocking connection barrel B 452  is arranged at an end of the blocking telescopic barrel B 450 , while a blocking telescopic inner barrel and a blocking mounting head are arranged on the other end of the blocking telescopic barrel B 450 . A buffer rod B 454  is installed in the blocking telescopic inner barrel, wherein the buffer rod B 454  is a hydraulic rod, which telescopic end is installed in the mounting opening groove B 481  with the end face thereof being tightly attached to the inner wall of the mounting opening groove B 481 . This design can cushion the impact force of the blocking corner block B 480  against the stop surface B 482 . Also, the stop surface B 482  is preferably not being tightly attached to the blocking mounting head B 453  in the initial state. 
     The blocking telescopic barrel B 450  has a blocking connection barrel B 452  with an end passing through the blocking affixing block B 410  and being assembled and affixed with a blocking limiting ring B 451 , wherein the blocking limiting ring B 451  cannot pass through the blocking affixing block B 410  and the blocking telescopic barrel B 450  is axially slidably assembled with the blocking affixing block B 410 . 
     A second blocking pin B 462  penetrates a blocking mounting head B 453  and a blocking corner block B 480 , so as to hinge the blocking mounting head B 453  and the blocking corner block B 480  through the second blocking pin B 462 , wherein a mounting opening groove B 481  is disposed on the blocking corner block B 480  and a torsion spring B 430  is sleeved on the portion of the second blocking pin B 462  located in the mounting opening groove B 481 . The torsion spring B 430  is utilized to provide a rotation force turning the blocking corner block B 480  toward the stop surface B 482  or a tension hindering the blocking corner block B 480  from turning away from the direction of the stop surface B 482 . 
     The first blocking pin B 461  is made of iron material, and when the first blocking pin B 471  respectively approaches the first blocking sensor B 471  and the second blocking sensor B 472 , the first blocking sensor B 471  and the second blocking sensor B 472  generate an electrical signal change or generate an electrical signal, thereby determining the position of the first blocking pin B 461 . In this embodiment, the first blocking sensor B 471  and the second blocking sensor B 472  employ an eddy current sensor or a proximity sensor. 
     The blocking wheel B 490  is circumferentially rotatably mounted on the third blocking pin B 463 , and the third blocking pin B 463  is mounted on the blocking corner block B 480 . 
     The stop surface B 482  is disposed on the blocking corner block B 480 , and the stop surface B 482  is facing the horizontal direction of the torsion spring B 430 , which is opposite to the direction of the conveying chain conveying the tooling plate, which enables the blocking wheel B 490  to hold down the tooling plate because the stop surface B 482  is tightly attached to the blocking mounting head B 453  when the blocking wheel B 490  is tightly attached to the tooling plate  200 , thereby preventing the blocking corner block B 480  from rotating. 
     Referring to  FIGS. 19-20 , the stroke switch B 520  includes a sensing part B 524  that is assembled with the stroke mounting block B 521  through a stroke shaft B 522 , and the stroke shaft B 522  can rotate axially. 
     A stroke connecting plate B 523  is affixed on the stroke mounting block B 521 , and a stroke rotating wheel B 525  is rotatably mounted on the stroke connecting plate B 523 . 
     In  FIGS. 19 , B 5251 , B 5252 , and B 5253  illustrate position changes of the stroke rotating wheel B 525  during actual use. 
     In  FIG. 20 , the stroke switch is mounted on the conveying line near the bottom wall B 110 , and B 5254  illustrates a position of the stroke rotating wheel B 525  in the initial state. 
     When in use, the stroke connecting plate B 523  is driven to drive the stroke shaft B 522  to rotate, and when the stroke shaft B 522  rotates to a preset angle, a built-in switch of the sensing portion B 524  will be triggered, so as to determine the positional relationship between the tooling plate and the stroke switch and the motion relationship of the tooling plate. The sensing part B 524  of the present embodiment may be an angle sensor that determines the state of the stroke connecting plate B 523  through detecting the rotation angle of the stroke shaft B 522 . Of course, it is preferable to select a stroke switch since the technology is relatively mature. Here, the preferred embodiment employs the JDHK-3L model stroke switch sold by the Yueqing City Ouheng Appliance Co., Ltd. 
     In the initial state, the first blocking pin B 461  is aligned with the first blocking sensor B 471 , and at this time, the top of the blocking wheel B 490  exceeds the height of the conveying guide groove (the bottom surface of the tooling plate  200 ). Besides, the stroke switch paired with the blocking device does not receive a signal input. The stroke connecting plate B 523  and the sensing part B 524  form an included angle. 
     When the second buffer block  220  of the tooling plate is just in contact with the stroke rotating wheel B 525 , the blocking wheel B 490  has not been in contact with the first buffer block  210 . At this time, the tooling plate continues to move towards the blocking wheel B 490  under the driving of the conveying chain and the second buffer block  220  drives the stroke connecting plate B 523  to rotate around the stroke shaft B 522  as the center until the stroke connecting plate B 523  is perpendicular to the sensing part B 524 . At this time, the blocking wheel B 490  is in contact with the first buffer block  210  and the stroke switch outputs a signal, so as to determine that the tooling plate  200  reaches the positioning position (the tooling plate reaches the positioning position above the positioning top plate B 310 ). Then, the jacking mechanism drives the positioning top plate B 310  to move upwards, so that the first positioning protruding shaft B 311  and the second positioning protruding shaft B 312  on the positioning top plate B 310  are respectively assembled with the first positioning hole  201  and the second positioning hole  202 , thereby completing the positioning of the banknote-receiving bucket, and allowing inputting banknotes into the banknote-receiving bucket. 
     After the banknote-receiving bucket finishes banknote-receiving, the push rod motor retracts to drive the blocking wheel B 490  to move downwards through the telescopic shaft, until the first blocking pin is aligned with the second blocking sensor, wherein the blocking wheel B 490  does not make contact with the tooling plate at this moment. That is, the banknote-receiving bucket can continue to move forward. The conveying chain transports the tooling plate to continue to move forward. The tool plate  200  rotates the stroke connecting plate B 523  for a certain angle with the stroke shaft B 522  as the center, so that the stroke switch outputs a second signal. At this time, it determines that the tooling plate is passing by. After the tooling plate has passed, the stroke switch will restore, so that the second signal output is interrupted. At this moment, it is determined that the tooling plate  200  has passed. 
     Referring to  FIGS. 24, 29, and 30 , the positioning mechanism B 300  comprises a positioning top plate B 310 , which has a first positioning protruding shaft B 311  and a second positioning protruding shaft B 312  arranged thereon, wherein the positioning top plate B 310  is affixed on a jacking beam B 320 . When in use, the jacking mechanism B 200  jacks the positioning top plate B 310  upward through lifting the jacking beam B 320 . As a result, the first positioning protruding shaft B 311  and the second positioning protruding shaft B 312  are respectively placed into the first positioning hole and the second positioning hole, Since the banknote-receiving bucket is affixed on the tooling plate  200 , the tooling plate  200  is coupled and assembled with the first positioning protruding shaft B 311  and the second positioning protruding shaft B  312 , and is also coupled and assembled with the conveying guide groove B 121 , so as to prevent the banknote-receiving bucket from deviation and deflecting in the non-height direction in the non-height direction, which ensures the positioning accuracy of the banknote-receiving bucket and the position accuracy of the banknote-receiving bucket in banknote-receiving, so as to prevent banknote scatter, banknote falling, and etc. during banknote receiving. 
     After the banknote receiving is completed, the conveying chain conveys the banknote-receiving bucket to the output lifting module for output, and then the jacking mechanism repositions. 
     Preferably, the second positioning hole  202  is a blind hole, and the positioning top plate B 310  has a plug B 313 , and the power input end of the plug B 313  is electrically connected with the second positioning protruding shaft B 312 . When in use, the second positioning protruding shaft B 312  passes through the second positioning hole  202  and then is conductively connected with the connection hole, so that the plug B 313  and the connector  300  form a current loop. At this time, an electrical signal is generated, and it is determined that the positioning top plate and the tooling plate are assembled in place. 
     Of course, it may also be that the plug B 313  is communicatively connected with the controller (CPU or MCU), and the connector  300  carries information such as the number of the banknote-receiving bucket, and after the connector  300  is plugged with the plug B 313 , the controller reads the information (similar to a USB disk inserted on a computer host) to determine whether it is the selected banknote-receiving bucket, and also determines that the positioning top plate and the tooling plate have completed the positioning assembly. 
     Referring to  FIGS. 21-27 , the jacking mechanism B 200  comprises at least two jacking assemblies and a jacking motor B 530 , wherein each of the jacking assemblies comprises a first jacking affixing plate B 211 , a second jacking affixing plate B 217 , and a third jacking affixing plate B 212 , wherein the first jacking affixing plate B 211  and the third jacking affixing plate B 212  are connected and affixed through a jacking connecting shaft B 213 , and the first jacking affixing plate B 211  is mounted on the conveying side plate B 120 . 
     The second jacking affixing plate B 217  is assembled and affixed with an end of a jacking guide shaft B 215  and the jacking beam B 320 , wherein the other end of the jacking guide shaft B 215  penetrates the third jacking affixing plate B 212  to be assembled and affixed with a jacking limiting plate B 216 , wherein the jacking limiting plate B 216  is prevented from passing through the third jacking affixing plate B 212 , and the jacking guide shaft B 215  and the third jacking affixing plate B 212  are axially movably assembled. 
     Further, A jacking lug plate B 230  is affixed on the second jacking affixing plate B 217 , wherein the jacking lug plate B 230  is assembled with the bearing shaft B 250 , and the bearing shaft B 250  is assembled and affixed with the inner ring of the bearing B 240 . 
     A shaft seat B 214  is mounted on the third jacking affixing plate B 212 , wherein the shaft seat B 214  is rotatably assembled with the jacking shaft B 650 . An eccentric wheel B 220  is mounted on the bearing B 240  at a position corresponding to the jacking shaft B 650 , wherein the eccentric wheel B 220  has a jacking groove B 221  arranged thereon. When the jacking mechanism jacks and lifts the jacking beam to the highest position, the jacking groove B 221  and the bearing B 240  are coupled and assembled, thereby providing a stable support for the bearing B 240 . 
     The third jacking affixing plate B 212  has a rotation limiting plate B 218  mounted in the vicinity of the eccentric wheel B 220 , wherein the rotation limiting plate B 218  has a rotation positioning sensor mounted thereon, wherein the rotation positioning sensor may be implemented as a pressure sensor, wherein when the eccentric wheel B 220  rotates to be coupled and assembled with the bearing B 240 , the eccentric wheel B 220  is pressed with the rotation positioning sensor, so that the rotation positioning sensor obtains a signal input for determining that the rotation is in place, and the jacking motor stops operating. The jacking shaft B 650  is connected with the jacking output shaft of the jacking motor B 530  through a coupler and the jacking motor B 530  is capable of driving the jacking shaft B 650  to rotate forward and reverse in the circumferential direction. 
     The third jacking affixing plate B 212  also has a reposition sensor B 260  mounted thereon, wherein the reposition sensor B 260  may be a proximity sensor or eddy current sensor, wherein an iron sensing block (not illustrated in the figures) is mounted on the first jacking affixing plate B 211  at a position corresponding to the reposition sensor B 260 . When the jacking mechanism is in a non-jacking state (initial state), the reposition sensor B 260  detects constant electrical signal and the electric signal value is large, so as to determine an initial state. When the reposition sensor B 260  detects gradually weaker electrical signal, a jacking period is determined. When the reposition sensor B 260  detects a constant electrical signal and the electrical signal value is small, a jacking state is determined. 
     When the jacking mechanism has jacked and needs to be repositioned, the jacking motor rotates reversely until the reposition sensor B 260  detects the electric signal of the initial state to stop the jacking motor from operating. 
     The judgment in this embodiment is to convert the related electrical signal into a digital signal to be input to a controller (CPU or MCU), and then perform comparison and judgment by means of a program built in the controller. 
     Referring to  FIGS. 31-37B , a banknote-receiving bucket conveying apparatus  1  according to a preferred embodiment of the present invention is illustrated. 
     The banknote-receiving bucket conveying device  1  can transport banknotes or coins, and is accurate in positioning in the transportation process, so as to prevent the banknotes or coins from falling out or being lost. 
     Specifically, the banknote-receiving bucket conveying device  1  comprises at least one lifting unit  10  and at least one conveying unit  20 , wherein when the quantity of the lifting units  10  is two, the conveying unit  20  can be located between the two lifting units  10 , and the conveying unit  20  is utilized for conveying at least one banknote-receiving bucket  30 , wherein the banknote-receiving bucket  30  is utilized for accommodating banknotes or coins. The banknote-receiving bucket  30  can be transported along the length direction of the conveying unit  20 . After the banknote-receiving bucket  30  is transported to the conveying unit  20 , the banknote-receiving bucket  30  can be positioned, and then the positioned banknote-receiving bucket  30  can be aligned to a banknote outlet. Then, corresponding banknotes and coins can be output to the banknote-receiving bucket  30  through the banknote outlet. 
     The lifting unit  10  is configured to drive the banknote-receiving bucket  30  to ascend and descend, so as to input or output the banknote-receiving bucket  30  in the conveying unit  20 . 
     The banknote-receiving bucket  30  can be conveyed to a position of the lifting unit  10  on the conveying unit  20  after banknote receiving, and then be output through the lifting unit  10 . 
     For example, one empty banknote-receiving bucket  30  may be input to the conveying unit  20  from the lifting unit  10  to receive banknotes or coins at a preset position of the conveying unit  20 . After the banknote-receiving bucket  30  is filled with banknotes or coins, it is then transported to the other lifting unit  10  for outputting. 
     The banknote-receiving bucket circulating conveying line apparatus  1  further comprises a positioning unit  40 , wherein the positioning unit  40  is disposed on the conveying unit  20  and is configured to assist in positioning the banknote-receiving bucket  30  relative to the conveying unit  20 , so that the banknote-receiving bucket  30  can be aligned with the banknote outlet. 
     Specifically, the banknote-receiving bucket circulating conveying line apparatus  1  comprises a support board  50 , wherein the banknote-receiving bucket  30  is supported on the support board  50 , and the support board  50  can be transported along a conveying channel  200  of the conveying unit  20 . 
     The positioning unit  40  comprises at least one jacking mechanism  41 , at least one limiting mechanism  42  and at least one blocking mechanism  43 , wherein the jacking mechanism  41 , the limiting mechanism  42 , and the blocking mechanism  43  are respectively arranged on the conveying unit  20 , and the jacking mechanism  41  can jack up and lift the limiting mechanism  42  to limit the banknote-receiving bucket  30 , and the blocking mechanism  43  is capable of blocking the banknote-receiving bucket  30 , so that the banknote-receiving bucket  30  can be limited by the limiting mechanism  42  in time. 
     The conveying unit  20  comprises a conveying motor  21 , a first conveying belt  22 , and a second conveying belt  23 , wherein the conveying motor  21  is capable of driving the first conveying belt  22  and the second conveying belt  23  to move, wherein the conveying channel  200  is located between the first conveying belt  22  and the second conveying belt  23 . 
     The banknote-receiving bucket  30  is supported between the first conveying belt  22  and the second conveying belt  23  through the support board  50 . The limiting mechanism  42  and the blocking mechanism  43  are respectively located between the first conveying belt  22  and the second conveying belt  23 . When the banknote-receiving bucket  30  is transported normally, the limiting mechanism  42  is not higher than the first conveying belt  22  and the second conveying belt  23 , so that the banknote-receiving bucket  30  can be smoothly transmitted; when the position of the banknote-receiving bucket  30  needs to be limited, the jacking mechanism  41  rises upwards to lift the limiting mechanism  42  to that at least a part of the limiting mechanism  42  is higher than the first conveying belt  22  and the second conveying belt  23 , thereby limiting the position of the banknote-receiving bucket  30 .

When the support board  50  supports the banknote-receiving bucket  30 , and is transported to the position where the blocking mechanism  43  is located by the conveying unit  20 , the protruding blocking mechanism  43  will prevent the banknote-receiving bucket  30  from continuing to move forward. 
     The banknote-receiving bucket circulating conveying line apparatus  1  further comprises a stroke switch  60 , wherein the stroke switch  60  can cooperate with the blocking mechanism  43  to record the strokes of the banknote-receiving bucket  30 . 
     The stroke switch  60  is disposed on the conveying unit  20  and is located in the conveying channel  200  of the conveying unit  20 . 
     At least a portion of the blocking mechanism  43  is configured to be movable. When the banknote-receiving bucket  30  needs to be blocked, at least a portion of the blocking mechanism  43  is higher than the support board  50  to prevent the support board  50  from moving forwards. When the banknote-receiving bucket  30  needs to continue to move forward, the protruding portion of the blocking mechanism  43  can move downwards to not be higher than the support board  50 , so that the support board  50  can support the banknote-receiving bucket  30  to continue to move forward. 
     In the process of moving the support board  50  towards the blocking mechanism  43 , when the support board  50  is in contact with the blocking mechanism  43 , the stroke switch  60  can output a signal, so as for determining that the support board  50  has reached the positioning position based on the signal. In other words, the support board  50  reaches the position above the limiting mechanism  42 . 
     The jacking mechanism  41  drives at least part of the limiting mechanism  42  to ascend, so that the support board  50  is positioned at the limiting mechanism  42 , thereby completing the positioning of the support board  50 , thereby completing the positioning of the banknote-receiving bucket  30 , so as for putting banknotes into the banknote-receiving bucket  30 . 
     After the banknote-receiving bucket  30  finishes banknote-receiving, the blocking portion of the blocking mechanism  43  can move downward to not block the support board  50 , and the support board  50  may then continue to move forward under the action of the conveying unit  20 . In this process, the stroke switch  60  may detect the stroke change of the support board  50  and emit another signal representing that the support board  50  is passing by the stroke switch  60 . After the support board  50  has completely passed, the stroke switch  60  may emit another signal, representing that the support board  50  has passed. 
     According to one embodiment of the present invention, the stroke switch  60  may be embodied as a detector, such as an infrared detector, a camera, and etc.. 
     The stroke switch  60  is communicatively connected with the jacking mechanism  41 , and the jacking mechanism  41  is capable of jacking up and lifting the limiting mechanism  42  based on the signal detected by the stroke switch  60 . 
     According to another embodiment of the present invention, the blocking mechanism  43  may have a sensor arranged thereon, and when the support board  50  is blocked by the blocking mechanism  43 , the jacking mechanism  41  communicatively connected with the blocking mechanism  43  may jack up the limiting mechanism  42 .

The push rod motor  434  is capable of pushing the blocking telescopic assembly  435 , so that the blocking telescopic assembly  435  can move telescopically. 
     The third blocking pin  436 C passes through the first blocking plate  432 A, the end of the push rod motor  434 , and the second blocking plate  432 B, such that the push rod motor  434  is mounted between the first blocking plate  432 A and the second blocking plate  432 B. 
     The push rod motor  434  has a telescopic shaft  4341 , wherein the telescopic shaft  4341  has a first mounting end and a second mounting end, wherein the first mounting end of the telescopic shaft  4341  is connected with the push rod motor  434 . This allows the telescopic shaft  4341  to be driven to be movably connected with the push rod motor  434  in an axial direction. 
     The second blocking plate  432 B has a first blocking sensor  437 A and a second blocking sensor  437 B, wherein the first blocking sensor  437 A and the second blocking sensor  437 B are respectively utilized for detecting the position of the first blocking pin  436 A, so as to determine the position of the blocking member  439 . 
     The first blocking sensor  437 A and the second blocking sensor  437 B are arranged on the second blocking plate  432 B along the length direction of the second blocking plate  432 B. It should be noted that the first blocking sensor  437 A and the second blocking sensor  437 B are located between the second mounting end of the mounting protruding shaft  4341  and the blocking telescopic assembly  435  to detect the movement of the blocking telescopic assembly  435 , thereby detecting the movement of the blocking member  439 . 
     Specifically, the blocking telescopic assembly  435  has a high end and a low end, wherein the blocking member  439  is located at the high end of the blocking telescopic assembly  435 , and the low end of the blocking telescopic assembly  435  is aligned with the position of the telescopic shaft  4341 . When the position of the blocking member  439  changes, the position of the blocking telescopic assembly  435  of the blocking member  439  changes, so that the position of the low end of the blocking telescopic assembly  435  changes, which allows the first blocking sensor  437 A and the second blocking sensor  437 B to detect the position change of the blocking member  439  through detecting the blocking telescopic assembly  435 . 
     The blocking member  439  may be implemented as a blocking wheel that can be in contact with the support board  50  supporting the banknote receiving bucket  30 . 
     Further, the blocking telescopic assembly  435  comprises a blocking limiting ring  4351 , a blocking connection barrel  4352 , a blocking mounting head  4353 , and a buffer rod  4354 , wherein the blocking limiting ring  4351  is affixedly assembled on the blocking affixing block  431 , and the blocking limiting ring  4351  is mounted at the low end of the blocking connection barrel  4352 . In other words, the low end of the blocking connection barrel  4352  passes through the blocking affixing block  431  and is connected with the blocking limiting ring  4351 . The blocking connection barrel  4352  and the blocking affixing block  431  of the blocking telescopic assembly  435  are axially slidably assembled. 
     The first blocking pin  436 A can pass through the blocking connection barrel  4352  and the second mounting end of the telescopic shaft  4341 , so that the blocking connection barrel  4352  and the telescopic shaft  4341  can be relatively assembled and affixed in the axial direction. 
     The blocking mounting head  4353  is mounted at the other end of the blocking connection barrel  4352 , wherein the blocking mounting head  4353  and the blocking limiting ring  4351  are respectively located at two ends of the blocking connection barrel  4352 . 
     The buffer rod  4354  is located in the blocking connection barrel  4352 , and the buffer rod  4354  has a telescopic end, wherein the telescopic end of the buffer rod  4354  may be connected with the blocking block  438 . 
     Specifically, the blocking block  438  is connected with the blocking member  439 , and when the blocking member  439  blocks the support board  50 , the blocking member  439  acts on the blocking block  438 , and the blocking block  438  transfers the acting force to the buffer rod  4354 . 
     The blocking mechanism  43  has a stop surface  430 , wherein the stop surface  430  may be formed on the blocking block  438 , wherein when the blocking member  439  blocks the support board  50 , the blocking block  438  moves downward. 
     The second blocking pin  436 B can pass through the blocking mounting head  4353  and the blocking block  438 , such that the blocking mounting head  4353  and the blocking block  438  can be hinged through the second blocking pin  436 B. 
     The blocking block  438  has a mounting opening groove  4380  arranged thereon and the torsion spring  433  is disposed on the second blocking pin  436 B passing through a portion of the mounting opening groove  4380 . The torsion spring  433  is utilized to generate a force that causes the blocking block  438  to turn to the stop surface  430  or generate an elastic force that prevents the blocking block  438  from rotating in a direction away from the stop surface  430 . 
     The first blocking pin  436 A may be made of iron material. When the first blocking pin  436 A approaches the first blocking sensor  437 A and the second blocking sensor  437 B respectively, the first blocking sensor  437 A and the second blocking sensor  437 B generate an electrical signal change or generate an electrical signal, so as to determine the position of the first blocking pin  436 A. According to this embodiment, the first blocking sensor  437 A and the second blocking sensor  437 B adopt an eddy current sensor. 
     The blocking member  439  is circumferentially rotatably mounted on the third blocking pin  436 C, wherein the third blocking pin  436 C is mounted on the blocking block  438 . The blocking member  439  may be implemented as a blocking wheel. 
     The stop surface  430  is located on the blocking block  438 , and the stop surface  430  faces the horizontal direction of the torsion spring  433  and the opposite direction of the conveying unit  20  conveying the support board  50 , which enables the blocking member  439  to stop and hold the support board  50 . Because the stop surface  430  and the blocking mounting head  4353  are tightly attached when the blocking member  439  and the support board  50  are tightly attached, the blocking block  438  is prevented from rotating, so that the support board  50  can be blocked and stopped. 
     Further, according to the preferred embodiment, the stroke switch  60  is mounted on the conveying frame  24  of the conveying unit  20 , and is located at an inner side of the conveying frame  24 . Specifically, the stroke switch  60  is located in the conveying channel  200  and is connected with the conveying frame  24 . The stroke switch  60  can be detected through the support board  50  to determine the stroke and position of the support board  50 . 
     When the support board  50  passes through the stroke switch  60 , at least a portion of the stroke switch  60  is located higher than the support board  50 . When the support board  50  passes, the portion of the stroke switch  60  automatically moves downward due to the action of the support board  50 . When the support board  50  leaves, the stroke switch  60  is repositioned to the original position. Based on the change of the stroke switch  60  in this process, the position of the support board  50  is recorded. 
     The stroke switch  60  comprises a fixed component and a rotatable component, wherein the rotatable component is installed on the fixed component, and the rotatable component is rotatably connected with the fixed component around the joint of the rotatable component and the affixed component. In an initial state, the rotatable component is higher than the fixed component. The rotatable component can be in contact with the support board  50 , and is capable of rotating downward due to the action of the support board  50 . 
     Specifically, referring to  FIGS. 36A and 36B , the stroke switch  60  includes a stroke mounting portion  61 , a stroke connecting portion  62 , a stroke sensing portion  63 , a stroke connecting shaft  64  and a stroke connecting wheel  65 , wherein the stroke sensing portion  63  is mounted on the stroke mounting portion  61 , wherein the stroke connecting shaft  64  is mounted on the stroke mounting portion  61 , wherein the stroke sensing portion  63  is capable of sensing rotation of the stroke connecting shaft  64 . 
     The stroke connecting portion  62  is connected with the stroke mounting portion  61  and the stroke connecting wheel  65 . The stroke connecting portion  62  is rotatable about the stroke connecting shaft  64  by a certain angle, and the stroke sensing portion  63  can detect a magnitude of a rotation angle of the stroke connecting portion  62 . The stroke connecting wheel  65  is mounted on the stroke connecting portion  62 . 
     For the stroke connecting portion  62 , the stroke connecting wheel  65  and the stroke mounting portion  61  are respectively connected with the stroke connecting portion  62 , wherein a certain distance is provided between the stroke connecting wheel  65  and the stroke mounting portion  61 . The stroke connecting portion  62  can rotate relative to the stroke mounting portion  61 , and an included angle, such as an included angle of  90  degrees, may be formed between the stroke connecting portion  62  and the stroke mounting portion  61 . 
     When in use, the stroke connecting portion  62  is driven to drive the stroke connecting shaft  64  to rotate, and when the stroke connecting shaft  64  rotates for an certain angle, the built-in detector of the stroke sensing portion  63  will be triggered, so as to determine a positional relationship between the support board  50  and the stroke switch  60  as well as a motion relationship of the support board  50 . 
     The stroke sensing portion  63  of the stroke switch  60  may be an angle sensor, and the state of the stroke connection portion  62  is determined by detecting the rotation angle of the stroke connection shaft  64 . 
     In the initial state, the first blocking pin  436 A and the first blocking sensor  437 A face each other. At this time, the top of the blocking member  439  is not lower than the height of the support board  50 , and the stroke switch  60  opposite to the blocking mechanism  43  does not have signal input. The stroke connecting portion  62  and the stroke sensing portion  63  form an included angle. 
     Referring to  FIGS. 32A and 32B , the support board  50  has a first buffer block  501  and a second buffer block  502 , wherein the first buffer block  501  and the second buffer block  502  are mounted on the side surfaces of the support board  50 , for example, respectively on two parallel sides. The first buffer block  501  and the second buffer block  502  have elasticity, which is utilized to buffer a force generated by a collision. According to this embodiment, the first buffer block  501  and the second buffer block  502  are made of elastic rubber. Certainly, it shall be understood that the first buffer block  501  and the second buffer block  502  may also be supported by other buffer materials, such as a foam material, a plastic material, and etc. 
     Referring to  FIGS. 38-43 , the working process of the banknote-receiving bucket conveying apparatus  1  according to the above preferred embodiment of the present invention is illustrated, wherein when the support board  50  approaches the blocking mechanism  43  and the stroke switch  60  and when the second buffer block  502  is in contact with the stroke connecting wheel  65  of the stroke switch  60 , the blocking member  439  of the blocking mechanism  43  is temporarily not in contact with the first buffer block  501 . The support board  50  continues to move forward under the action of the conveying unit  20  and moves towards the blocking mechanism  43 , wherein the second buffer block  502  drives the stroke connecting portion  62  to rotate around the stroke connecting shaft  64  until the stroke connecting portion  62  and the stroke sensing portion  63  are perpendicular or reach a predetermined angle, wherein the blocking member  439  of the blocking mechanism  43  is in contact with the first buffer block  501 , and at this time, the stroke switch  60  outputs a signal to determine that the support board  50  has reached the positioning position. 
     Then, the jacking mechanism  41  drives at least part of the limiting mechanism  42  to ascend, so as to affix the support board  50  to the limiting mechanism  42 , thereby completing the limiting and positioning of the banknote-receiving bucket  30 , and allowing input banknotes into the banknote-receiving bucket  30 . 
     After the banknote-receiving bucket  30  completes the banknote receiving, the push rod motor  434  drives the blocking member  439  of the blocking mechanism  43  to move downward through driving the telescopic shaft  4341  to retract until the first blocking pin  436 A and the second blocking sensor  437 B are aligned. At this time, the blocking member  439  faces the support board  50  and the banknote-receiving bucket  30  can continue to move forward under the action of the conveying unit  20 . 
     The movement of the support board  50  renders the stroke connection portion  62  of the stroke switch  60  to rotate at a certain angle around the stroke connection shaft  64  as the center, so that the stroke switch  60  outputs a second signal. At this time, it can be determined that the support board  50  is passing by, and after the support board  50  passes, the stroke switch  60  can reset and the second signal will be interrupted. At this moment, it can be determined that the support board  50  has passed. 
     Further, according to this embodiment, referring to  FIG. 34 , the limiting mechanism  42  includes a limiting top plate  421 , a first positioning protrusion  422 , and a second positioning protrusion  423 , wherein the first positioning protrusion  422  and the second positioning protrusion  423  are respectively disposed on the limiting top plate  421 . 
     Correspondingly, also referring to  FIG. 32B , the support board  50  has a first positioning groove  510  and a second positioning groove  520 , wherein when the limiting top plate  421  is lifted from bottom to top towards the support board  50 , the first positioning protrusion  422  and the second positioning protrusion  423  may enter the first positioning groove  510  and the second positioning groove  520  of the support board  50  respectively, so as to limit and position the support board  50  on the limiting top plate  421 . 
     It should be noted that, according to some other embodiments of the present invention, the first positioning groove  510  and the second positioning groove  520  may be provided on the limiting top plate  421 , and the first positioning protrusion  422  and the second positioning protrusion  423  may be provided on the support board  50 . According to another embodiment of the present invention, the first positioning groove  510  and the second positioning protrusion  423  may be located on the limiting top plate  421 , wherein the first positioning protrusion  422  and the second positioning groove  520  may be provided on the support board  50 . 
     The support board  50  and the limiting mechanism  42  may be buckled and assembled with each other, so as to prevent the banknote-receiving bucket  30  from deviating in a non-height direction, thereby ensuring the positioning accuracy of the banknote-receiving bucket  30  and the accuracy of the position of the banknote-receiving bucket  30  during banknote receiving, so as to reduce the problems of the banknote receiving scattered, banknote falling, and etc. 
     After the banknote-receiving bucket  30  finishes banknote-receiving, the conveying unit  20  transports the banknote-receiving bucket  30  to the lifting unit  10  for output, and the jacking mechanism  41  may be reset. 
     Optionally, the second positioning groove  520  may be a blind hole. 
     The support board  50  may also have a connector  503 , wherein the connection hole of the connector  503  faces to the second positioning groove  520 . In other words, the connection hole of the connector  503  and the second positioning groove  520  are aligned along the same axis. 
     The limiting mechanism  42  further includes a plug  424 , wherein a power input end of the plug  424  of the limiting mechanism  42  is electrically connected with the second positioning protrusion  423 . When in use, the second positioning protrusion  423  can pass through the second positioning groove  520  to be conductively connected with the connection hole of the connector  503 , so that the connector  503  and the plug  424  of the limiting mechanism  42  form a current circuit. At this time, an electrical signal is generated to determine that the limiting top plate  421  of the limiting mechanism  42  and the support board  50  are assembled in place. 
     Further, the plug  424  of the limiting mechanism  42  may also be communicatively connected with a controller, wherein the connector  503  located on the support board  50  may carry identity information, such as a serial number and etc., of the banknote-receiving bucket  30 . After the plug  424  of the limiting mechanism  42  is connected with the connector  503 , the controller may read the information carried by the connector  503 , and then determine whether the banknote-receiving bucket  30  currently connected with the support board  50  of the limiting mechanism  42  is the selected banknote-receiving bucket  30  as well as possibly further determine whether the limiting top plate  421  of the limiting mechanism  42  and the support board  50  have completed positioning and assembling. 
     Further, the jacking mechanism  41  comprises a jacking assembly  411 , a jacking motor  412 , and a jacking detector  413 , wherein the jacking motor  412  is communicatively connected with the jacking detector  413 , and when the support board  50  is transported to a predetermined position, the jacking detector  413  obtains a signal, and the jacking motor  412  jacks up and lifts at least part of the jacking assembly  411  based on the signal obtained by the jacking detector  413 , so as to jack up and lift the limiting top plate  421  of the limiting mechanism  42 . 
     The jacking assembly  411  comprises a jacking bottom plate  4111 , a jacking connecting shaft  4112 , and a jacking top plate  4113 , wherein the jacking top plate  4113  is located above the jacking bottom plate  4111 , and the jacking connecting shaft  4112  is respectively connected with the jacking bottom plate  4111  and the jacking top plate  4113 . The jacking bottom plate  4111  is affixedly mounted on the conveying frame  24  of the conveying unit  20 . 
     The jacking top plate  4113  is mounted to the jacking connecting shaft  4112  in a back-and-forth shiftable manner relative to the jacking bottom plate  4111 . 
     The jacking connecting shaft  4112  has a first connecting end and a second connecting end, wherein the first connecting end of the jacking connecting shaft  4112  is connected with the jacking top plate  4113 , and the second connecting end of the jacking connecting shaft  4112  is connected with the jacking bottom plate  4111 . 
     When the jacking top plate  4113  is jacked up, it may be by means of extending the portion of the first connecting end of the jacking connecting shaft  4112 , or extending the portion of the second connecting end of the jacking connecting shaft  4112 . 
     Specifically, the jacking assembly  411  further comprises a jacking connecting rod  4114 , a jacking supporting member  4115 , and a jacking rotating member  4116 , wherein the jacking supporting member  4115  is arranged on the jacking connecting rod  4114 , and the jacking connecting rod  4114  is rotatably connected with the jacking motor  412  in a drivable manner. The jacking rotating member  4116  is connected with the jacking top plate  4113  and can be supported by the jacking supporting member  4115 . 
     When the jacking top plate  4113  needs to be jacked up, the jacking motor  412  drives the jacking connecting rod  4114  to rotate, so that the jacking supporting member  4115  connected with the jacking connecting rod  4114  and located below the jacking top plate  4113  rotate correspondingly, wherein the jacking supporting member  4115  has a supporting surface  41151 , wherein the heights of the supporting surface  41151  at different positions are different. When the jacking supporting member  4115  rotates, the contact positions of the jacking supporting member  4115  and the jacking rotating member  4116  are different, so that the jacking rotating member  4116  can be jacked up. 
     The jacking rotating member  4116  is rotatably connected with the jacking top plate  4113 , wherein when the jacking supporting member  4115  rotates along with the jacking connecting rod  4114 , the jacking rotating member  4116  can rotate, so that the joint position of the jacking rotating member  4116  and the jacking supporting member  4115  is affixed relative to the jacking bottom plate  4111 , thereby facilitating the stability of the entire jacking mechanism  41 . 
     Optionally, the supporting surface  41151  may form a certain radian, such as being a concave supporting surface  41151  and etc., so that the jacking rotating member  4116  can be stably supported on the jacking supporting member  4115 . 
     The jacking detector  413  may be configured to detect or determine when the jacking mechanism  41  needs to be jacked up and lifted, whether the jacking mechanism  41  is in place, and when jacking and repositioning needs to be performed. 
     For example, the jacking detector  413  may be mounted on the jacking top plate  4113 , and when the jacking motor  412  drives to lift the jacking top plate  4113  to a certain height, the jacking detector  413  sends a signal to the jacking motor  412  to stop the operation of the jacking motor  412 . 
     It should be noted that the jacking mechanisms  41  may be linked. When a plurality of the banknote-receiving buckets  30  are provided on the conveying unit  20 , and all the banknote-receiving buckets  30  are blocked by the corresponding blocking mechanisms  43  respectively, the jacking mechanism  41  jacks up the limiting top plates  421  of the corresponding limiting mechanisms  42  at the same time. 
     Specifically, the jacking connecting rod  4114  of the jacking assembly  411  of the jacking mechanism  41  may be connected with the jacking supporting members  4115  of a plurality of the jacking assemblies  411 , so that when the jacking connecting rod  4114  is driven to rotate, the plurality of jacking top plates  4113  can be lifted at the same time. 
     After the banknote-receiving bucket  30  is positioned at a preset position of the conveying unit  20  under the action of the jacking mechanism  41 , the jacking mechanism  41  will be repositioned and the limiting top plate  421  of the limiting mechanism  42  affixedly connected with the jacking top plate  4113  of the jacking mechanism  41  will move down, so that the banknote-receiving bucket  30  can continue to be transported along the conveying channel  200 . 
     According to the preferred embodiment, the conveying unit  20  includes two conveying channels  200 , and the two conveying channels  200  communicate with each other through the lifting unit  10 . 
     Specifically, the banknote-receiving bucket  30  of the conveying channel  200  located above is conveyed to the lifting unit  10 , and then the lifting unit  10  transports the banknote-receiving bucket  30  to the conveying channel  200  located below, wherein the banknote-receiving bucket  30  of the conveying channel  200  located below is transported to the other lifting unit  10 , and then the lifting unit  10  transports the banknote-receiving bucket  30  to the other conveying channel  200  located above. 
     Of course, the lifting unit  10  may also output the banknote-receiving bucket  30  to other positions. Here are merely examples and are not intended to limit the present invention. 
     Referring to  FIGS. 37A and 37B , the lifting unit  10  comprises a platform  11 , a lifting rail  12 , a lifting motor  13 , and a lifting frame  14 , wherein the lifting rail  12  and the lifting motor  13  are respectively mounted on the lifting frame  14  and the platform  11  is movably mounted on the lifting rail  12 . The lifting rail  12  is drivably connected with the lifting motor  13  in a movable manner. 
     When the lifting track  12  is driven by the lifting motor  13  to move, the platform  11  connected with the lifting track  12  may also follow the lifting track  12  to move up and down. 
     The platform  11  has a track  110  arranged thereon, wherein the track  110  of the platform  11  can be aligned with the conveying channel  200  of the conveying unit  20 , such that the banknote-receiving bucket  30  located on the conveyance unit  20  can be directly transported to the track  110  of the platform  11 . The support board  50  is connected with the banknote-receiving bucket  30 , and the support board  50  and the banknote-receiving bucket  30  are transported to the track  110  of the platform together during transportation. 
     When the banknote-receiving bucket  30  needs to be transported from the platform  11  towards other positions, the track  110  may be driven to move so as to transport the banknote-receiving bucket  30  and the support board  50  located on the track  110  outward to, for example, another conveying channel  200 . 
     The lifting unit  10  further comprises a lifting sensor  15 , wherein the lifting sensor  14  is mounted on the lifting frame  15 , and the lifting sensor  15  can be utilized for detecting the height of the platform  11  to determine whether the platform  11  and the conveying channel  200  are in the same horizontal position, so as to determine whether the banknote-receiving bucket  30  can be transported between the lifting unit  10  and the conveying unit  20  in a subsequent step. 
     According to another aspect of the present invention, the present invention provides a conveying method of a banknote-receiving bucket, comprising the steps of: 
     conveying the banknote-receiving bucket  30  along the conveying channel  200 ; and 
     blocking the banknote-receiving bucket  30  in a predetermined position through extending the blocking mechanism  43  from the conveying channel  200 . 
     According to the embodiments of the present invention, the banknote-receiving bucket  30  is limited to a fixed position after the banknote-receiving bucket  30  is blocked. 
     According to the embodiments of the present invention, the banknote-receiving bucket is limited through lifting the limiting top plate  421  to be assembled with the support board  50 . 
     According to the embodiments of the present invention, the position of the support board  50  is determined through the stroke switch  60 .
