Abstract:
A coordinate measuring system is provided having a pair of rotary laser devices vertically spaced from one another with the same rotational axis C. Each rotary laser device radiates fan-shaped laser beams inclined off of the horizontal towards a photosensor device. The photosensor device receives the fan-shaped laser beams to obtain tilt angles α, β against the horizontal plane and then obtains a height of the photosensor device and horizontal distance X from the rotary laser devices to the photosensor device, based on both of the tilt angles. Further, this operation part measures a rotation angle from a reference direction based on time difference generated when the fan-shaped laser beams, mutually-rotating in the reverse direction, are received at the photosensor device located on an unknown point D 2.  Coordinates of the unknown point D 2  are calculated based on the rotation angle and the coordinates of at least two known points.

CROSS-REFERENCE TO RELATED APPLICATIONS  
       [0001]     This application is based upon and claims the benefit of priority from the prior Japanese Patent Application JP2005-265832 filed on Sep. 13, 2005, the entire content of which is incorporated herein by reference.  
       FIELD OF THE INVENTION  
       [0002]     Present invention relates to the sheet-like paper products conveying route switching apparatus for switching conveying route of sheet-like paper products.  
       BACKGROUND OF THE INVENTION  
       [0003]     Conventionally, in a conveying apparatus for conveying sheet-like paper product by clamping with conveyor belts, a method of guiding the leading end of sheet-like paper product in a designated direction according to a rocking type conveying route switching mechanism placed along the conveying path for switching between two ways is disclosed in the Japanese patent document, JP2002-367003A.  
         [0004]     However, since the method disclosed in the patent document JP2002-367003A is of rocking to obstruct the conveying path, it tends to cause faults, such as a fault of sheet-like paper product being damaged or being jammed when sheet-like paper product passes during rocking of the switching mechanism. In order to prevent these faults, it was needed to widen spacing between sheet-like paper products conveyed in considerable extent. Therefore, there was a defect that the processing efficiency of sheet-like paper products becomes down.  
         [0005]     Further, in a portion where the switching mechanisms are provided continuously, since sheet-like paper product cannot be clamped by conveyor belts, it is employed a method of guiding sheet-like paper products by incurvating the sheet-like paper product itself to a barrel roof form with which the form hardly collapses. However, since in the sheet-like paper product with a weak drape, such as a bill, the form collapsed easily, and thus a leading end thereof are hardly guided correctly, there was still a defect of easily causing a paper jam.

       First Embodiment  
       [0018]      FIG. 1  is a schematic section of a sheet-like paper products conveying route switching apparatus according to the first embodiment of the present invention.  
         [0019]     In this first embodiment, the sheet-like paper products conveying route switching apparatus is equipped in a sheet-like paper product processing apparatus which conveys sheet-like paper products at high speed and processes them. For example, lo it is an apparatus for switching conveying paths of the sheet-like paper product which clamp sheet-like paper products such as bank notes by the conveying belts, and convey from a first conveying path to a second conveying path or from the first conveying path to a third conveying path.  
         [0020]      FIG. 2  is a drawing explaining pneumatic operation bodies employed in the first embodiment, for example, a first pneumatic operation body  1 . In more detail,  FIG. 2   a  is a top view,  FIG. 2   b  is a front view,  FIG. 2   c  is a bottom view, and  FIG. 2   d  is a side elevation.  
         [0021]     The pneumatic operation body  1  is connected to pneumatic operation control device  3  via pneumatic tube  3 D, and provided with pneumatic tube connection part  101  forming port opening of air, and openings  102  and  103  for intaking or discharging air. The openings  102  and  103  are communicated to pneumatic tube connection part  101  through pneumatic run  104 .  
         [0022]     The openings  102  and  103  open at grooves which guide runnings of conveyor belts  5 A. The width and the depth of the groove are enlarged a little than the width and the thickness of conveyor belt  5 A, so that perforated conveyor belt  5 A can run smoothly. The second pneumatic operation body  2  is constituted lo likewise the first pneumatic operation body  1 .  
         [0023]      FIG. 3  is a top view of perforated conveyor belt  5 A employed for this embodiment, for example, the first transportation belt. The second conveyor belt  5 B is constituted likewise the first conveyor belt  5 A.  
         [0024]     Referring now to  FIGS. 1-3 , the constitution and the operation of the sheet-like paper products conveying route switching apparatus of the first embodiment will be explained.  
         [0025]     The sheet-like paper products conveying route switching apparatus of the first embodiment is provided with parallel two pairs of conveyor belts, i.e., perforated first conveyor belt  5 A running from first conveying path to second conveying path through the first pneumatic operation body  1 , and perforated second conveyor belt  5 B running from first conveying path to third conveying path through the second pneumatic operation body  2 . These parallel pairs of conveyor belts convey sheet-like paper product P by clamping it.  
         [0026]     Sheet-like paper product P conveyed by being clamped by the first and second conveyor belts  5 A and  5 B is detected by the first sensor  8  placed along the first conveying path.  
         [0027]     The first and the second pneumatic operation bodies  1  and  2  are each formed grooves for guiding runnings of first and second conveyor belts  5 A and  5 B.  
         [0028]     Further, first and second pneumatic operation control devices  3  and  4  are coupled between pneumatic operation bodies  1  and  2  and a pneumatic pump (not shown). These pneumatic operation control devices  3  and  4  control the pneumatic operation of pneumatic operation bodies  1  and  2 .  
         [0029]     Further, a first pinch-roller pair  13  for supporting the first and the second conveyor belts  5 A,  5 B by clamping them, second roller pair  14  for supporting the first and third conveyor belts  5 A,  11  by clamping them, third roller pair  15  for supporting the second and fourth conveyor belts  5 B,  12  by clamping them are provided. And separation guide  7  is placed at a separation zone of the second conveying path and the third conveying path.  
         [0030]     The first conveyor belt  5 A is perforated holes at constant interval. Through the holes, intaking or discharging of air is possible. Further, the first conveyor belt  5 A brings sheet-like paper products P in conveying route switching section by clamping them in corporation with the second conveyor belt  5 B, and then conveys the paper products P brought by clamping in corporation with the third conveyor belt  11 .  
         [0031]     Like the first conveyor belt  5 A, the second conveyor belt  5 B is perforated holes at constant interval. Through the holes, intaking or discharging of air is possible. Further, the second conveyor belt  5 B brings the sheet-like paper products P in conveying route switching section by clamping them in corporation with the first conveyor belt  5 A, and then conveys the paper products P brought by clamping in corporation with the fourth conveyor belt  12 .  
         [0032]     The above-described conveyor belts  5 A,  5 B,  11  and  12  are each supported by respective pinch-roller pair  13 - 15 , and driven in synchronism with each other by drive motor (not shown).  
         [0033]     Pneumatic operation control device  3  is a system for controlling electro-magnetic valve  3 B to perform air-intake/air-discharge/pause for the first pneumatic operation body  1 .  
         [0034]     Pneumatic tube  3 A is connected to the air supply port of electro-magnetic valve  3 B, and thus air is supplied through the pneumatic tube  3 A. This pneumatic tube  3 A is connected to the compressor (not shown), and thus air is supplied from the compressor.  
         [0035]     Pneumatic tube  3 C is connected to the air discharge port of electro-magnetic valve  3 B, and when control of air-discharge/air-intake is not carried out to pneumatic operation body  1 , the air supplied from pneumatic tube  3 A is discharged from the pneumatic operation body  1 .  
         [0036]     Pneumatic tube  3 D is connected to air control port of electro-magnetic valve  3 B, and then control of air-intake/air-discharge/pause is carried out to pneumatic operation body  1  through the pneumatic tube  3 D. Now, this air control is carried out by the pneumatic operation control device.  
         [0037]     Pneumatic operation control device  4  is a system for controlling electro-magnetic valve  4 B to perform air-intake/air-discharge/pause for the first pneumatic operation body  2 . As well, since pneumatic operation control device  4  is constituted in identical to pneumatic operation control device  3 , description of the pneumatic operation control device  4  will be omitted.  
         [0038]     Now, an operation for conveying the sheet-like paper product P in the direction of the second conveying path by the sheet-like paper products conveying route switching apparatus of the first embodiment will be explained. Following operations are controlled by the pneumatic operation control device (not shown) for controlling sheet-like paper products conveying route switching apparatus.  
         [0039]     When sheet-like paper product P is detected by the first sensor  8 , pneumatic control means controls the electro-magnetic valve  3 B to carry out the air-intake from openings  102  and  103  opening at the groove for guiding the first conveyor belt  5 A of pneumatic operation body  1 , and makes sheet-like paper product P be attracted to the first conveyor belt  5 A. According to this air-intake operation, sheet-like paper product P is conveyed in the direction of the second conveying path which is the running direction of the first conveyor belt  5 A.  
         [0040]     Further, sheet-like paper product P is brought into the second conveying path by being supported by the first conveyor belt  5 A and the third conveyor belt  11  which are supported their running by pinch-roller pair  14 . Here, it is further preferred that when sheet-like paper product P is pulled to pneumatic operation body  1  the air-discharge operation of the second pneumatic operation body  2  is carried out for pressing the sheet-like paper product P against the first conveyor belt  5 A. This operation is effective when two pieces of sheet-like paper product are conveyed in succession, as described in detail later.  
         [0041]     When conveying sheet-like paper product P in the direction of the third conveying path by the sheet-like paper products conveying route switching apparatus, air-intake operation through openings  102  and  103  opening at the groove for guiding the first conveyor belt  5 B of pneumatic operation body  2  is carried out to attract sheet-like paper product P to the second conveyor belt  5 B. According to this air-intake operation, sheet-like paper product P is conveyed in the direction of the third conveying path which is the running direction of the second conveyor belt  5 B. Here, it is further preferred that when sheet-like paper product P is pulled to pneumatic operation body  2  the air-discharge operation of the second pneumatic operation body  1  is carried out for pressing the sheet-like paper product P against the first conveyor belt  5 B. This operation is effective when two pieces of sheet-like paper product are conveyed in succession, as described in detail later.  
         [0042]     Further, sheet-like paper product P is brought into the third conveying path by being supported by the second conveyor belt  5 B and the third conveyor belt  12  which are supported their running by pinch-roller pair  15 .  
         [0043]     Next, it will be explained about that two consecutive sheet-like paper products Pa, Pb are conveyed to the second carrying path and the third carrying path, respectively.  
         [0044]     When sheet-like paper product Pa is detected by the first sensor  8 , pneumatic control means controls the electro-magnetic valve  3 B to carry out the air-intake from openings  102  and  103  opening at the groove for guiding the first conveyor belt  5 A of pneumatic operation body  1 , and makes sheet-like paper product Pa be attracted to the first conveyor belt  5 A. At the same time as that, the electro-magnetic valve  4 B is also operated to carry out the air-discharge operation of the second pneumatic operation body  2  to press the sheet-like paper product Pa against the first conveyor belt  5 A.  
         [0045]     In this situation, the leading end of sheet-like paper product Pa is conveyed in the direction of the second conveying path by running of conveyor belts  5 A,  5 B,  11 , and  12 . When the leading end of sheet-like paper product Pa has been clamped by the second conveying path pinch-roller  14 , the sheet-like paper product Pa is conveyed in the direction of the second conveying path even though the pneumatic operation body  1  has paused the air-intake operation.  
         [0046]     Further since no mechanism element such as rocking member working in accordance with the electro-magnetic valve  3 B on the conveying path, there is no danger of that the sheet-like paper product Pa is not damaged by operation of such mechanism element when the electro-magnetic valve  3 B has worked.  
         [0047]     When the detection output of the second sensor  9  has changed to OFF state, it is assumed that sheet-like paper product Pa has been held by the second conveying path pinch-roller  14 . Then the electro-magnetic valve  3 B is so changed to make the pneumatic operation body  2  to air-intake operation state and the pneumatic operation body  1  into the air-discharge operation state. Thereby, sheet-like paper product Pb is conveyed in the direction of the third conveying path.  
         [0048]     The separation guide is constituted to prevent that the sheet-like paper product conveyed to the second conveying path or the third conveying path is accidentally conveyed to the other-side conveying path. Here, the separation guide  7  is provided for preventing that at this time the trailing end part of the sheet-like paper product Pa is brought into the third conveying path by being attracted to the second conveyor belt  5 B.  
         [0049]     By having such construction free from mechanism element such as rocking member, the first embodiment is able to consecutively convey sheet-like paper products with very narrow spaces between them. Further the first embodiment is able to reliably convey even feeble sheet-like paper product by making pneumatic operation body  1  to air-intake operation state and pneumatic operation body  2  to the air-discharge operation state.  
       Second Embodiment  
       [0050]      FIG. 4  is a schematic section of the sheet-like paper products conveying route switching apparatus according to the second embodiment of the present invention.  
         [0051]      FIG. 5  is a perspective view of pneumatic operation roller device  30  ( 31 ) employed in this second embodiment.  
         [0052]     This second embodiment is almost same as the first embodiment except that first and second pneumatic operation roller devices  30  and  31  are employed instead of first and second pneumatic operation bodies  1  and  2  in first embodiment and non-perforated conveyor belts  6 A and  6 B are employed.  
         [0053]     That is, sheet-like paper products conveying route switching apparatus according to this first embodiment is provided with a first conveyor belt  6 A constituted for running from the first conveying path to the second conveying path through first air operation roller  30 , and a second conveyor belt  6 B constituted for running from the first conveying path to the third conveying path through second air operation roller  31 . Then, sheet-like paper products are conveyed as clamped between the first conveyor belt  6 A and the second conveyor belt  6 B.  
         [0054]     The sheet-like paper product P conveyed by the first and second conveyor belts  6 A and  6 B is detected by the first sensor  8  placed along the first conveying path.  
         [0055]     The first and second pneumatic operation roller devices  30  and  31  are provided with rollers. The rollers are constituted to support the runnings of the first and second conveyor belts  6 A and  6 B conveying the sheet-like paper product P and to bring the sheet-like paper product P therein, respectively. And the rollers are perforated with a plurality of holes  301  for carrying out air-intake operation and/or air-discharge operation.  
         [0056]     Further these pneumatic operation roller devices  30  and  31  are provided with pneumatic operation control devices  3  and  4  for charging or discharging air thereto. Further, a plurality of pinch-roller pairs  13 - 15  for supporting the first and second conveyor belts  6 A,  6 B by clamping them are provided. And a separation guide  7  is placed at a separation zone of the second conveying path and the third conveying path.  
         [0057]     Here, the components similar to those in the pneumatic operation control devices  3  and  4  of the first embodiment will be assigned with the same reference numerals and the detailed explanation thereof will be omitted, and those different from the embodiment will be described.  
         [0058]     Although in the first embodiment pneumatic tubes  3 A and  4 A are connected to air supply opening of electro-magnetic valves  3 B and  4 B, in this second embodiment those pneumatic tubes  3 A and  4 A are not employed. This is because that the pneumatic operation roller devices  30  and  31  of the second embodiment carries out air-intake operation and pause operation but not carry out air-discharge operation.  
         [0059]     The rollers of the pneumatic operation roller devices  30  and  31  are formed in hollow cylinder and perforated a plurality of holes on the circumference surface of the roller. Revolving shaft of the pneumatic operation roller devices  30  and  31  are connected to a compressor (not shown) through pneumatic tube  3 C,  3 D,  4 C and  4 D, and electro-magnetic valves  3 B and  4 B.  
         [0060]     Now, operations for conveying two consecutive sheet-like paper products Pa and Pb to the second conveying path and the third conveying path according to the sheet-like paper products conveying route switching apparatus of the first embodiment respectively will be explained.  
         [0061]     When the first sensor  8  detects the leading end of sheet-like paper product Pa, electro-magnetic valve  3 B is operated to carry out air-intake operation through the holes  301  of the rollers of pneumatic operation roller device  30 , and attract sheet-like paper product Pa.  
         [0062]     In this situation, the leading end of sheet-like paper product Pa is conveyed in the direction of the second conveying path by running of conveyor belts  5 A,  5 B,  11 , and  12 . When the leading end of sheet-like paper product Pa has been clamped by the second conveying path pinch-roller  14 , the sheet-like paper product Pa is conveyed in the direction of the second conveying path even though the pneumatic operation roller device  30  has paused the air-intake operation. Therefore, when detection output of the second sensor  9  turns ON, and the second conveying path pinch-roller  14  clamps the sheet-like paper product Pa, electro-magnetic valve  3 B is paused and air-intake operation of the pneumatic operation roller device  30  is suspended.  
         [0063]     When the first sensor  8  detects the leading end of sheet-like paper product Pa, electro-magnetic valve  4 B is operated to carry out air-intake operation through the holes  301  of the rollers of pneumatic operation roller device  31 , and attract sheet-like paper product Pb.  
         [0064]     In this situation, the leading end of sheet-like paper product Pb is conveyed in the direction of the third conveying path by running of conveyor belts  6 A,  6 B,  11 , and  12 . When the leading end of sheet-like paper product Pb has been clamped by the third conveying path pinch-roller  15 , the sheet-like paper product Pb is conveyed in the direction of the third conveying path even though the pneumatic operation roller device  31  has paused the air-intake operation. Therefore, when detection output of the third sensor  10  turns ON, and the third conveying path pinch-roller  15  clamps the sheet-like paper product Pb, electro-magnetic valve  4 B is paused and air-intake operation of the pneumatic operation roller device  31  is suspended.  
         [0065]     Here, the separation guide  7  is provided for preventing that the sheet-like paper product Pa is brought into between pinch-roller  15  and pneumatic operation roller device  31 , or that the sheet-like paper product Pb is brought into between pinch-roller  14  and pneumatic operation roller device  30 .  
         [0066]     According to this second embodiment, it is able to confine to only air-intake operation and pause operation, and thus the constitution of the sheet-like paper products conveying route switching apparatus becomes simplified. This second embodiment is suitable for a case that sheet-like paper product is rigid and thus it is no need of air-discharge operation.  
       Third Embodiment  
       [0067]      FIG. 6  is a schematic section of pneumatic operation body according to third embodiment of the present invention.  
         [0068]     In this third embodiment, air-discharge type pneumatic operation body is provided instead of air-intake type pneumatic operation bodies  1 ,  2  of first embodiment. Since pneumatic operation control devices  3  and  4  and conveyor belts  11  and  12  are the same as those of first embodiment, description of those will be omitted and those different from the embodiment will be described. The first pneumatic operation body  40  has pneumatic tube connection part  401 , and air is supplied from pneumatic operation control device  3  connected to the pneumatic tube connection part  401 . The supplied air passes through pneumatic run  402 , and is discharged from air-discharge opening  403  opening at a portion near the trailing end of the first pneumatic operation body  40 . In this embodiment, air-discharge operation and the pause operation are controlled by the opening and closing of electro-magnetic valve  3 B.  
         [0069]     In the first embodiment, the air-intake operation is preponderantly carried out and the air-discharge operation is supplementarily carried out. On the other hand, only the air-discharge operation is carried out. Air discharge opening  403  of the first pneumatic operation body  40  is constituted to blow air out in a front oblique direction, and pushes the leading end of sheet-like paper product P out in the direction of the third conveying path.  
         [0070]     This sheet-like paper products conveying route switching apparatus of third embodiment is provided with a pair of first conveyor belt  6 A constituted for running from the first conveying path to the second conveying path through first air operation roller  40 , and a pair of second conveyor belt  6 B constituted for running from the first conveying path to the third conveying path through second air operation roller (not shown). Then, sheet-like paper products are conveyed as clamped between the first conveyor belts  6 A and the second conveyor belts  6 B.  
         [0071]     The sheet-like paper product P conveyed by the first and second conveyor belts  6 A and  6 B is detected by the first sensor  8  placed along the first conveying path.  
         [0072]     The first and the second pneumatic operation bodies  40  and  41  are each formed grooves for guiding runnings of third and fourth conveyor belts  6 A and  6 B, and perforated a plurality of holes for passing air.  
         [0073]     The first and the second pneumatic operation bodies  40  and  41  are constituted to be supplied air from first and second pneumatic operation control devices (not shown). Further, first pinch-roller pair  13  for supporting the first and the second conveyor belts  5 A,  5 B by clamping them, second pinch-roller pair  14  for supporting the first and third conveyor belts  5 A,  11  by clamping them, third pinch-roller pair  15  for supporting the second and fourth conveyor belts  5 B,  12  by clamping them are provided. And separation guide  7  is placed at a separation zone of the second conveying path and the third conveying path. Further, Branching guide  7  is formed in a plurality of pinch-roller pairs  13 - 15  which pinch and support the first and second conveyor belts  6 A and  6 B of the above, and the distribution part of the direction of the second conveying path, and the direction of the third conveying path.  
         [0074]     With the second conveyor belt  6 B, the first conveyor belt  6 A clamps sheet-like paper product P, takes it in among the first and second pneumatic operation bodies  40  and  41 , and clamps sheet-like paper product P with the third conveyor belt  11 , and conveys it to the second conveying path.  
         [0075]     With the first conveyor belt  6 A, the second conveyor belt  6 B clamps sheet-like paper product P, and takes it in among the first and second pneumatic operation bodies  40  and  41 , and it clamps and conveys sheet-like paper product P with the fourth conveyor belt  12 .  
         [0076]     According to the place explained above, when conveying to the second conveying path, it sprays, only electro-magnetic valve  4 B of guide  41  is turned ON, and electro-magnetic valve  3 B of the first pneumatic operation body  40  is turned OFF, for example.  
         [0077]     Now, the operation in the case of conveying two consecutive sheet-like paper products Pa and Pb of two sheets to the second conveying path and the third conveying path, respectively with the sheet-like paper products conveying route switching apparatus by the first and second pneumatic operation bodies  40  and  41  of the first embodiment will be explained. The example at the time of changing and employing the first and second pneumatic operation bodies  40  and  41  of the first embodiment for pneumatic operation bodies  1  and  2  of the sheet-like paper products conveying route switching apparatus shown in  FIG. 1  will be explained.  
         [0078]     When the first sensor  8  detects the leading end of sheet-like paper product Pa, electro-magnetic valve  4 B is operated, air is blown out from air-discharge opening  403  of blasting guide  41 , and sheet-like paper product Pa is forced on the first pneumatic operation body  40 .  
         [0079]     In this situation, the leading end of sheet-like paper product Pa is conveyed in the direction of the second conveying path by running of conveyor belts  6 A,  6 B,  11 , and  12 . When the leading end of sheet-like paper product Pa has been clamped by the second conveying path pinch roller  14 , the sheet-like paper product Pa is conveyed in the direction of the second conveying path even though the pneumatic operation body  41  has paused the air-intake operation. Therefore, when detection output of the second sensor  9  turns ON, and the second conveying path pinch roller  14  clamps the sheet-like paper product Pa, electro-magnetic valve  4 B is paused and air-intake operation of the pneumatic operation body  41  is suspended.  
         [0080]     When the first sensor  8  detects the leading end of sheet-like paper product Pb, electro-magnetic valve  3 B is operated, air is blown out from air-discharge opening  403  of blasting guide  40 , and sheet-like paper product Pa is forced on the first pneumatic operation body  40 .  
         [0081]     When conveyor belts  6 A,  6 B,  11 , and  12  run in the condition, the leading end of sheet-like paper product Pa is conveyed in the direction of the second conveying path. Even if it does not carry out spraying by pneumatic operation body  40  after the leading end of sheet-like paper product Pb is clamped by the second conveying path pinch roller  14 , sheet-like paper product Pb is conveyed in the direction of the third conveying path. Therefore, when it detects that the detection output of the second sensor  10  was set to ON, and the third conveying path pinch roller  15  clamped sheet-like paper product Pb, electro-magnetic valve  3 B is suspended and blowing air by pneumatic operation body  40  is suspended.  
         [0082]     Here, the separation guide  7  is provided for preventing that the sheet-like paper product Pa is brought into between pinch roller  15  and pneumatic operation roller device  41 , or that the sheet-like paper product Pb is brought into between pinch roller  14  and pneumatic operation roller device  40 .  
         [0083]     By having such construction it is able to obtain the same effect as that of second embodiment.  
         [0084]     By employing the air-intake/air-discharge operation, the conveying route of sheet-like paper product can be switched at very high speed compared with the case where a rocking mechanism is used. Therefore, since the conveying density and/or conveying speed of the sheet-like paper products can be raised, an efficiency of processing sheet-like paper products can be raised.
