FIELD

The embodiments of the present application relate to a paper-type article collecting device for collecting paper-type articles such as banknotes, checks, securities and the like inside the device, and particularly relate to a recycle box.

BACKGROUND

Recycle boxes are widely used in the financial equipment, and are core mechanisms prepared for functions such as storage, arranging, conveying, bundling and transportation. The recycle box, after being assembled with components such as a housing member (for example, a box body), forms a recycle box, a circulation box, and a temporary storage module.

The currently described mechanism employing an impeller to stack banknotes is just a typical and common recycle box. In order to ensure the insertion of the paper-type articles, the impeller should have a relatively large diameter in a depth direction, the minimum diameter is about 83 mm, and the maximum diameter is about 160 mm, or to avoid using an impeller having a large diameter, the mechanical structure and electrical control need to be updated.

The recycle box in the conventional technology has drawbacks that the impeller has a large diameter and thus is not adapted to a narrow space, and the recycle box has a large volume.

SUMMARY

A recycle box is provided according to the embodiments of the present application, which employs an impeller having flexible blades to enable the impeller to be still usable normally in a narrow space, and the impeller has a small diameter and the recycle box may have a reduced volume accordingly.

A recycle box in the technical solution according to an embodiment of the present application includes: a box door and a box bottom housing. A recycle inlet is provided at a top of the box bottom housing, a guide elastic strip, a banknote guiding plate, an impeller, and a banknote stacking plate configured to stack recycled media are fixed inside the box bottom housing. The impeller has a plurality of flexible blades. The guide elastic strip and the banknote guiding plate are arranged vertically and face to face, and there is a gap between the guide elastic strip and the banknote guiding plate, and the gap is a recycle passage. The banknote guiding plate is provided with a first stopper for placing the recycled media and an opening for the flexible blade to pass through, and the recycled media are placed on the first stopper after passing through the recycle inlet and the recycle passage. The flexible blade conveys the recycled media on the first stopper onto the banknote stacking plate when the flexible blades are rotated out of the opening.

Preferably, the banknote guiding plate includes a first banknote guiding vertical surface, a banknote guiding toothed surface, a banknote guiding circular-arc surface, an banknote guiding inclined surface and a second banknote guiding vertical surface which are connected in the listed sequence. There is a gap between the guide elastic strip and the first banknote guiding vertical surface, and the banknote guiding toothed surface is the first stopper and is configured to temporarily store the recycled media passing through the recycle inlet and the recycle passage sequentially.

Preferably, the guide elastic strip includes an guiding inclined surface and a guiding vertical surface connected to a lower end of the guiding inclined surface, the distance between the guiding inclined surface and the first banknote guiding vertical surface is decreased gradually, and a distance between the guiding vertical surface and the first banknote guiding vertical surface is equal to a minimum distance between the guiding inclined surface and the first banknote guiding vertical surface.

Preferably, the recycle inlet is enclosed by a left guide tooth and a right guide tooth.

Preferably, the number of the impeller is at least two, and the guide elastic strip is positioned between each adjacent impellers.

Preferably, a maximum distance between the guiding inclined surface and the first banknote guiding vertical surface is equal to a distance between the left guide tooth and the right guide tooth or is greater than the distance between the left guide tooth and the right guide tooth by 1 mm to 3 mm.

Preferably, the distance between the guiding vertical surface and the first banknote guiding vertical surface ranges from 2 mm to 5 mm.

Preferably, the banknote stacking plate is a flat surface or an inclined surface.

Preferably, a banknote guiding circular-arc fillet and a third banknote guiding vertical surface are provided inside the box door, and the banknote stacking plate is located between the third banknote guiding vertical surface and the second banknote guiding vertical surface.

Preferably, an elastic component is connected between the banknote stacking plate and a bottom portion of the box bottom housing, and the elastic component is compressed by the banknote stacking plate when the recycled media are stacked on the banknote stacking plate.

The present application has beneficial effects as follows. Since the guide elastic strip, the banknote guiding plate, the impeller and the banknote stacking plate are fixed inside the box bottom housing of the recycle box, and the guide elastic strip and the banknote guiding plate are vertically and oppositely arranged, and a gap, i.e. the recycle passage is formed between the guide elastic strip and the banknote guiding plate, and the recycle passage is used for allowing the falling of the recycled media. When the recycled media fall onto the first stopper of the banknote guiding plate which is configured to temporarily store the recycled media after passing through the recycle inlet and the recycle passage, the flexible blade of the impeller passes through the opening of the banknote guiding plate and is rotated out of the opening of the banknote guiding plate, and the flexible blade conveys the recycled media on the first stopper onto the banknote stacking plate. When the flexible blade comes into contact with the banknote stacking plate as the recycled media increase in the process of rotation, it will be deformed to a certain extent and not be restored to the original shape. With the technical solution, since the flexible blade may be continually deformed, the impeller may have a reduced diameter, and thus the volume of the recycle box will be reduced accordingly.

DETAILED DESCRIPTION

A recycle box is provided according to an embodiment of the present application which can be configured to recycle media such as banknotes (paper currencies), checks or securities. In this embodiment, the structure and connecting relationship of the components of the recycle box are explained by taking banknotes (paper currencies) as the recycled media of the recycle box100. It is to be noted that, the type of the media to be recycled can be paper-type articles such as banknotes (paper currencies), checks or securities, and is not specifically limited in practical application.

The technical solutions in the embodiments of the present application will be described clearly and completely hereinafter in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all of other embodiments, made by those skilled in the art without any creative efforts, fall into the scope of the present application.

As shown inFIG. 1, a recycle box100includes a box door8and a box bottom housing1connected to the box door8. The box door8may be opened to allow the banknotes inside the box bottom housing1to be taken out.

A recycle inlet is provided at the top of the box bottom housing1. A guide elastic strip2, a banknote guiding plate3, an impeller4and a banknote stacking plate6are fixed inside the box bottom housing1. An elastic component5is connected between the banknote stacking plate6and a bottom portion of the box bottom housing1. The guide elastic strip2and the banknote guiding plate3are arranged vertically and arranged face to face, and a gap is included between the guide elastic strip and the banknote guiding plate and defines a recycle passage. The banknote guiding plate3is provided with a first stopper and the banknotes fall onto the stopper after passing through the recycle inlet and the recycle passage. The banknote guiding plate3is provided with an opening for a flexible blade4aof the impeller4to pass through, and the flexible blade4amay rotate by 360 degrees about an impeller shaft. When being rotated out of the opening of the banknote guiding plate3, the flexible blade4aconveys the banknotes on the first stopper of the banknote guiding plate3onto the banknote stacking plate6and the banknote stacking plate6is configured to stack banknotes.

With the technical solution described above, since the guide elastic strip, the banknote guiding plate, the impeller and the banknote stacking plate are fixed inside the box bottom housing of the recycle box, and the guide elastic strip and the banknote guiding plate are arranged vertically and arranged face to face, and a gap, i.e. the recycle passage is formed between the guide elastic strip and the banknote guiding plate, and the recycle passage is used for receiving the fallen recycled media, when the recycled media fall onto the first stopper of the banknote guiding plate configured to temporarily store the recycled media after passing through the recycle inlet and the recycle passage, the flexible blade of the impeller passes through the opening of the banknote guiding plate and is rotated out of the opening of the banknote guiding plate, and the flexible blade conveys the recycled media on the first stopper onto the banknote stacking plate. In the rotation process, as the recycled media increase, the flexible blade may be deformed to a certain extent when coming into contact with the banknote stacking plate and may not be restored to the original shape. With the technical solution, since the flexible blade may be continually deformed, the impeller may have a small diameter, and thus the volume of the recycle box may be reduced accordingly.

Preferably, as shown inFIGS. 2 and 3, the banknote guiding plate3includes a first banknote guiding vertical surface3a, a banknote guiding toothed surface3c, a banknote guiding circular-arc surface3d, a banknote guiding inclined surface3e, and a second banknote guiding vertical surface3bwhich are connected in the listed sequence. The first stopper described above is the banknote guiding toothed surface3c. The banknote guiding circular-arc surface3dis transitionally connected to the first banknote guiding vertical surface3athrough the banknote guiding toothed surface3cwith saw teeth. The first banknote guiding vertical surface3aextends upward from a tip end on a right side of the banknote guiding toothed surface3c. The second banknote guiding vertical surface3bis located below the banknote guiding circular-arc surface3dwhich is coplanar with the first banknote guiding vertical surface3a. The second banknote guiding vertical surface3bis transitionally connected to the banknote guiding circular-arc surface3dthrough the banknote guiding inclined surface3e.

The toothed saw teeth of the banknote guiding toothed surface3cfunction as a cushion when a banknote falls onto the banknote guiding toothed surface3c, and allows several banknotes200to be vertically arranged on the banknote guiding toothed surface3cat the same time. The uppermost banknote may be conveyed toward the second banknote guiding vertical surface3bof the banknote guiding plate3when the blade of the impeller4slides toward the top surface of the banknote stacking plate6, which is advantageous for order stacking of the collected banknotes.

The impeller4may be mounted at an axis position of the banknote guiding circular-arc surface3dof the banknote guiding plate3. The impeller4is provided with uniformly distributed blades4a, each of the blades4ahas flexibility functioning to allow the size of the housing to be reduced, and has a certain rigidity functioning to stabilize a rotational conveying of the banknotes.

Preferably, as shown inFIG. 1, the guide elastic strip2includes an guiding inclined surface2aand a guiding vertical surface2bconnected to a lower end of the banknote guiding inclined surface. A distance between the guiding inclined surface2aand the first banknote guiding vertical surface3aof the banknote guiding plate3is decreased gradually. The distance between the guiding vertical surface2band the first banknote guiding vertical surface3ais the same as a minimum distance between the guiding inclined surface2aand the first banknote guiding vertical surface3a.

The reason why the distance between the guiding inclined surface2aand the first banknote guiding vertical surface3aof the banknote guiding plate3is gradually decreased is that: the recycle box100, as a module required to be frequently removed so as to be opened for counting of banknotes, is required to hand over banknotes with an original passage opening of the machine core. In order to enable the banknotes to enter he recycle box100so as to realize a reliable banknote-passing, a box body inlet passage of the recycle box should be wider; the gap between the guiding vertical surface2band the first banknote guiding vertical surface3aof the banknote guiding plate3is equal to the minimum gap between the guiding inclined surface2aand the first banknote guiding vertical surface3aof the banknote guiding plate3to ensure the banknotes to be reliably and stably transferred to the passage with a normal width from the wider passage.

Preferably, as shown inFIG. 1, the recycle inlet is formed by a left guide tooth1aand a right guide tooth1b, which is convenient for handing over the banknotes entering from other modules. The distance from the banknote guiding toothed surface3cto the left guide tooth1aand the right guide tooth1bof the recycle inlet of the box bottom housing1should be greater than a maximum width of the banknotes to be collected. The guide elastic strip2may be mounted at an inner side of a lower portion of the left guide tooth1aof the box bottom housing1. There is a gap between the guiding inclined surface2aand the first banknote guiding vertical surface3aof the banknote guiding plate3, and the gap defines a recycle passage. A maximum width of the gap between the guiding inclined surface2aand the first banknote guiding vertical surface3aof the banknote guiding plate3is equal to a width of a gap between the left guide tooth1aand the right guide tooth1bor is greater than the width of the gap between the left guide tooth1aand the right guide tooth1bby 1 mm to 3 mm. The guiding vertical surface2band the first banknote guiding vertical surface3aface to face with a gap therebetween ranging from 2 mm to 5 mm. The banknote guiding plate3is mounted at an inner side of a lower portion of the right guide tooth1bof the box bottom housing1, and the first banknote guiding vertical surface3ais coplanar with a banknote-passing surface of the right guide tooth1bor slightly deviates rightwards with respect to the banknote-passing surface.

Preferably, the box door8is hinged to the box bottom housing1, and is capable of rotating about a door shaft8cto be opened for counting the banknotes. A circular-arc-shaped guiding fillet8ais provided at an inner side of an upper part of the box door8. A stacking space for the banknotes is defined by the second banknote guiding vertical surface3bof the banknote guiding plate3and the third banknote guiding vertical surface8bof the box door8together. The banknote stacking plate6is located between the third banknote guiding vertical surface8band the second banknote guiding vertical surface3b. The space is slightly greater than the width of the banknotes to be collected, for example the space is greater than the width of the banknotes to be collected by 3 mm to 5 mm.

Preferably, the elastic component may be a banknote stacking plate restoring spring5, the shape of which is not limited to a tapered or cylindrical shape. The banknote stacking plate6is mounted at a central top of the banknote stacking plate restoring spring5. Whether or not the banknote stacking plate6is equipped with a shaft having a guide effect does not affect the realization of the functions of the mechanism.

Preferably, as shown inFIGS. 1 and 7, the impeller4has at least one blade, and the number of the blades is not limited to four as illustrated. The orderliness degree of the banknotes200being stacked by the impeller4depends on the number of the blades, a rotational speed of the impeller and a banknote feeding speed. The manner in which the banknotes are conveyed is determined by the number of the blades when the rotational speed of the blades and the speed of advancement of the banknotes are constant. As shown inFIG. 7a, the time during which the blade4aas shown inFIG. 1(horizontally arranged) is switched to the blade4bas shown inFIG. 7is just sufficient for one banknote200to enter. In this case, if the number of the blades is less than four, more than one banknote200is allowed to be temporarily stacked on the banknote guiding toothed surface3cof the banknote guiding plate3. The banknotes are forced to rotate by the blade4bwhen being conveyed, and the blade4bis not spaced apart from the banknote stacking plate6. As shown inFIG. 7b, if the number of the blades is greater than four, the banknotes200are pressed by the blades to slide over the banknote guiding circular-arc fillet8aon the box door1, and the blades4b,4care respectively located at a front side and a rear side of the banknote, which is advantageous for the turnover conveying of the banknotes, i.e., the banknotes200are spaced apart from the banknote stacking plate6by the blade4c. If the banknotes are not spaced apart from the banknote stacking plate6by the blade4c, the banknotes200may fall onto the banknote stacking plate6freely when the impeller4is stopped due to a failure, which is disadvantageous for the order stacking of the banknotes. The spaced design can effectively avoid this issue.

Preferably, as shown inFIG. 8, the number of the impellers4is at least two, and the guide elastic strip may be more than one. The guide elastic strip2is located between adjacent impellers4, and the impellers4and the guide elastic strips2are alternately arranged.

Preferably, as shown inFIG. 9, the shape of the top surface of the banknote stacking plate6may be changed into various forms, such as an inclined plane61or a cambered surface62, to reduce a driving force required when the blade slides, which may not affect the function of the present application.

The operation process of the recycle box will be explained in conjunction withFIGS. 3 to 6, the drive and detection systems of the impeller4are not illustrated and the impeller4is unidirectionally rotated counterclockwise.

As shown inFIG. 4, when there is no banknote on the banknote stacking plate6, the banknote stacking plate is located at an upper limit position under the action of the banknote stacking plate restoring spring5.

When the banknotes are required to enter the recycle box100, a control section issues an instruction such that the impeller4rotates counterclockwise, and the banknotes, after entering via the space between the left guide tooth1aand the right guide tooth1b, fall along the guiding inclined surface2aof the guide elastic strip2, and the recycle passage defined by the guiding vertical surface2band the first banknote guiding vertical surface3aof the banknote guiding plate3in sequence onto the banknote guiding toothed surface3cof the banknote guiding plate.

As shown inFIGS. 4 and 5, when one of the blades of the impellers4, such as the blade4b, is rotated out of the opening of the banknote guiding plate3, the banknotes200may be pressed against a lower portion of the blade4bin the rotational direction while being conveyed to the banknote stacking plate6along the banknote guiding plate3.

After the banknotes enter continuously, the banknote stacking plate restoring spring5is compressed under the deadweight of the banknote stacking plate6, the weight of the banknotes stacked and a pressing component force generated by the flexible blades of the impeller4sliding across the top of the banknotes stacked, thus vacating an upper part space for collecting banknotes, as shown inFIG. 6, till the banknote stacking plate restoring spring5is pressed to a maximum degree and it is detected that the capacity of the recycle box100reaches the limit (the detection system is not shown).

A control system may control the operation timing of the impeller4, and the impeller4may always rotate counterclockwise, which will not affect the functions described in this application.
