The application claims the priority of Chinese patent application with application No. 201110004944.2, titled as “sheet medium processing device”, and filed on Jan. 11, 2011, and all disclosed contents thereof should be incorporated herein by reference.
The present invention relates to a sheet medium processing device.
Common sheet mediums include train tickets, plane tickets, checks, and cashes etc., and automatic processing including stacking, distributing and recycling etc., needs to be performed for sheet mediums in more and more industries and fields with the popularization of automatic services.
For example, a cash dispenser mechanism in the financial system is able to stack, transport and recycle cashes, and a ticket issuing device in the railway system is able to stack, transport and recycle ticket paper. Traditional sheet medium processing devices have problems of complicated structures, multiple components, and high costs etc.
To solve these problems, Chinese patent application with application No. 200810027225.0 discloses a sheet medium processing device. The device comprises: a frame; an input passage mounted on the frame; a hub component, mounted on the frame, located at the exit of the input passage and configured to transport sheet mediums to a stacking and arranging assembly; the stacking and arranging assembly comprising a support plate configured to stack and receive the sheet mediums, limiting side plates set at two sides of the support plate and configured to align the sheet mediums, and a unidirectional rotational baffle set in a transport passage of the sheet mediums; a transport assembly, connected with the support plate and configured to drive the support plate to deliver the sheet mediums.
The solution has the following disadvantages: when bent, the stacked sheet mediums are aligned irregularly in the vertical direction due to the lack of a pressing device above the support plate. When the support plate carries the sheet mediums, and outputs the sheet mediums from the device, the output position is blocked easily. Therefore, the device, which requires high medium flatness, can be hardly adapted to different types of mediums.
The purpose of the present invention is to provide a sheet medium processing device with simple structure and high medium adaptability as well as functions including stacking, aligning, transporting and recycling etc.
Therefore, the present invention provides a sheet medium processing device, comprising a stacking mechanism, a first switching mechanism and a retractable paper baffle adjacent to the medium exit of the stacking mechanism, which are mounted on a frame, wherein the stacking mechanism comprises a lower ticket stacking assembly, an upper ticket stacking assembly capable of moving parallelly above the lower ticket stacking assembly and a parallel movement confining mechanism configured to limit the moving trajectory of the upper ticket stacking assembly, wherein the upper ticket stacking assembly and the lower ticket stacking assembly respectively comprise a bracket, a belt, and at least two belt pulleys mounted on the bracket to support the belt, wherein a passage for transporting mediums or a space for stacking mediums is formed between the belt of the upper ticket stacking assembly and the belt of the lower ticket stacking assembly. The upper ticket stacking assembly has a tendency of moving towards the lower ticket stacking assembly by gravity, wherein the first switching mechanism simultaneously controls the reciprocation of the paper baffle and the parallel movement of the upper ticket stacking assembly, enabling the stacking mechanism to be selectively in a transport state and a stacking state.
Further, the stacking mechanism further comprises: a first elastic element configured to enable the upper ticket stacking assembly to have the tendency of moving towards the lower ticket stacking assembly.
Further, the first switching mechanism comprises: a push plate hinged on the frame by a hinge shaft to rotate around the hinge shaft, and having an initial position and a lifting position; a cam, provided below the push plate and configured to rotate the push plate from the initial position to the lifting position; a third elastic element, configured to have the push plate being in a tendency of maintaining at the initial position, wherein the push plate has a second edge abutted against the periphery of the cam and a third edge for pushing the upper ticket stacking assembly away from the lower ticket stacking assembly when the push plate is at the lifting position.
Further, the first switching mechanism further comprises: a swinging bracket comprising a left side wall and a right side wall which are pivoted on the frame, and a connection wall extended transversely between the left side wall and the right side wall, wherein the paper baffle is provided on the connection wall; and a second elastic element configured to have the paper baffle on the swinging bracket being in a tendency of stretching out, wherein the push plate further has a first edge pushing the paper baffle on the swinging bracket to retract when the push plate is at the initial position.
Further, the paper baffle and the swinging bracket are integrated.
Further, the left side wall and the right side wall of the swinging bracket are provided with a pressing portion abutted against the first edge of the push plate.
Further, both the left side wall and the right side wall of the swinging bracket are provided with a stop portion adapted to locate a core shaft of the belt pulley of the lower ticket stacking assembly.
Further, the push plate is provided with an arc groove centered on the hinge shaft and the frame is provided with a locating pin located in the arc groove.
Further, the first switching mechanism further comprises a third driving mechanism for controlling the paper baffle independently. The third driving mechanism comprises a rack fixedly connected with the paper baffle, a gear driving the rack to move up and down, and a motor driving the gear to rotate.
Further, the lower ticket stacking assembly is hinged with the frame via a core shaft of the belt pulley adjacent to the medium exit, wherein the sheet medium processing device further comprises a second switching mechanism enabling the lower ticket stacking assembly to deflect around the core shaft.
Further, the second switching mechanism comprises: an inner gear ring fixedly connected with a bracket of the lower ticket stacking assembly and centered on the axle center of the core shaft of the belt pulley adjacent to the medium exit; a gear provided on the frame and in meshing transmission with the inner gear ring; and a driving mechanism for driving the gear to rotate.
Further, the deflection range of the lower ticket stacking assembly is between a medium discharge position and a medium recycling position. The medium recycling position is provided with a recycling box.
Further, the parallel movement confining mechanism comprises a plurality of connecting rods, wherein the plurality of connecting rods, together with the upper ticket stacking assembly and the lower ticket stacking assembly form a four-rod mechanism.
Further, the plurality of connecting rods are set in parallel, and the plurality of connecting rods, together with the upper ticket stacking assembly and the lower ticket stacking assembly form a four-rod mechanism.
In the present invention, the first switching mechanism adjusts the position relation between the upper ticket stacking assembly and the lower ticket stacking assembly of the stacking mechanism, and the position relation of the paper baffle relative to the exit or the passage for transporting mediums so as to stack, align and transport sheet mediums. When the upper ticket stacking assembly and the lower ticket stacking assembly are separated, the paper baffle is blocked at the downstream of the lower ticket stacking assembly along the medium transportation direction so that mediums transported one by one can be stacked on the lower ticket stacking assembly and aligned along the paper baffle. When the upper ticket stacking assembly is in contact with the lower ticket stacking assembly, a first belt of the upper ticket stacking assembly is tangent with a second belt of the lower ticket stacking assembly to form a sheet medium transportation passage and the paper baffle retracts at the moment.
During the transportation process, the belt of the upper ticket stacking assembly is tightly pressed against the lower ticket stacking assembly via the self-gravity of the upper ticket stacking assembly or the elasticity of the first elastic element so as to adjust and limit the vertical-direction state of multiple stacked sheet mediums, thereby achieving reliable transportation even if the sheet mediums are bent, and improving the adaptability of the device to mediums. In addition, different transportation directions can be formed by adjusting the rotating angle of the stacking mechanism through the second switching mechanism so as to transport sheet mediums to different destinations as required.

An entrance 51 is provided at one end of the second belt pulley 112 and the fourth belt pulley 122 adjacent to the stacking mechanism 1, and an exit 53 is provided at the other end of the stacking mechanism 1. Therefore, when the stacking mechanism 1 is in the stacking position, sheet mediums enter from the entrance 51 and are stacked between the first belt 113 and the second belt 123. When the stacking mechanism is in the transport position, the stacking mechanism 1 may discharge mediums clamped between the first belt 113 and the second belt 123 out of the sheet medium processing device via the exit 53.

The swinging bracket 21 is located below the lower ticket stacking assembly 12, and a left side wall 215 and a right side wall 216 of the swinging bracket 21 are hinged with the frame 5 via a hinge portion 211. A paper baffle portion 212 is provided between the left side wall 215 and the right side wall 216 of the swinging bracket 21. The paper baffle portion 212 is capable of stretching into the exit 53 or retracting from the exit 53 when the swinging bracket 21 swings. A pressing portion 213 for driving the swinging bracket 21 to rotate is provided on the left side wall 215 and/or the right side wall 216 of the swinging bracket 21. A stop portion 214 oppositely matched with the core shaft 121a of the third belt pulley 121 of the lower ticket stacking assembly 12 is further provided on the left side wall 215 and/or the right side wall 216 of the swinging bracket 21 to limit the rotation angle of the swinging bracket 21 towards the direction of the exit 53.
One end of the second elastic element 25 is connected with the swinging bracket 21 and the other end is connected with the frame 5. Under the elasticity of the second elastic element 25, the swinging bracket 21 always has a tendency of rotating towards the direction of the exit 53 by taking the hinge portion 211 as the circle center. Therefore, the paper baffle portion 212 always has a motion tendency of extending into the exit 53.
The cam 23 is hinged with the frame 5 via the rotating shaft 231 and can rotate around the rotating shaft 231. The periphery of the cam 23 comprises a first working face 232 and a second working face 233, wherein the first working face 232 has a first preset distance away from the rotating shaft 231, and the second working face 233 has a second preset distance away from the rotating shaft 231. The first preset distance is shorter than the second preset distance.
The push plate 22 is hinged with the frame 5 via a hinge shaft 225 and can rotate around the hinge shaft 225. A limiting groove 224 matched with a limiting shaft 52 on the frame 5 is provided on the surface of the push plate 22. The limiting groove 224 is an arc groove centered on the hinge shaft 225. The width of the limiting groove 224 is matched with the diameter of the limiting shaft 52. The length of the limiting groove 224 is greater than the diameter of the limiting shaft 52.

The interaction relation between the first switching mechanism and the stacking mechanism will be explained below in combination with
As shown in
At the same time, the upper ticket stacking assembly 11 presses against the lower ticket stacking assembly 12 under the action of the first elastic element 14. Supported and limited by the parallel movement confining mechanism, the position of the upper ticket stacking assembly 11 relative to the lower ticket stacking assembly 12 is stable. At this moment, the first belt 113 of the upper ticket stacking assembly 11 is tangent with the second belt 123 of the lower ticket stacking assembly 12, and a passage for transporting mediums is formed therebetween. Therefore, the stacking mechanism 1 can be driven to the transport position by correlative movements of the components of the first switching mechanism 2.
In other variant embodiments, the paper baffle portion 212 may be shaped independently, i.e. the paper baffle portion and the swinging bracket 21 are two components.
As shown in
At the same time, since the first edge 221 of the push plate 22 is separated from the pressing portion 213 of the swinging bracket 21, the swinging bracket 21 rotates around the hinge portion 211 under the elasticity of the second elastic element 25. The stop portion 214 of the swinging bracket 21 is in contact and matched with the core shaft 121a of the third belt pulley 121 of the lower ticket stacking assembly 12. At this moment, the paper baffle portion 212 of the swinging bracket 21 extends into the exit 53 and is located at the downstream of the stacking mechanism 1. Therefore, the stacking mechanism 1 can be driven to the stacking position by correlative movements of all components of the first switching mechanism 2.
A working process of the sheet medium processing device provided by the present invention is introduced below.
When mediums need to be stacked, a control device (not shown in the figures) of the sheet medium processing device controls the cam 23 of the first switching mechanism 2 to rotate to the second set position. At this moment, the cam 23 rotates to drive the push plate 22 and the swinging bracket 21 to rotate, so that there is a preset distance between the first belt 113 of the upper ticket stacking assembly 11 and the second belt 123 of the lower ticket stacking assembly 12 and a space for accommodating and stacking the mediums is formed therebetween. The first belt 113 and the second belt 123 are in a static state, and the paper baffle portion 212 of the swinging bracket 21 extends into the exit 53.
The sheet mediums enter the space between the upper ticket stacking assembly 11 and the lower ticket stacking assembly 12 one by one. Since the paper baffle portion 212 of the swinging bracket 21 is located at the downstreams of the upper ticket stacking assembly 11 and the lower ticket stacking assembly 12, the sheet mediums are blocked on the surface of the lower ticket stacking assembly 12 by the paper baffle portion 212 and aligned along the paper baffle portion 212.
After a certain amount of sheet mediums are stacked, the sheet mediums stored on the surface of the lower ticket stacking assembly 12 temporarily need to be sent out once. The control device of the sheet medium processing device controls the second driving mechanism 24 to drive the cam 23 to rotate to the first set position. At this moment, the cam 23 rotates to drive the push plate 22 and the swinging bracket 21 to move. Under the action of the first elastic element 14, the upper ticket stacking assembly 11 presses towards the lower ticket stacking assembly 12 to clamp the stacked mediums between the first belt 113 of the upper ticket stacking assembly 11 and the second belt 123 of the lower ticket stacking assembly 12. Subsequently, the first driving mechanism 15 drives the first belt 113 and the second belt 123 to move synchronously to send out the neatly-stacked sheet mediums.
The sheet mediums stacked by the sheet medium processing device provided by the present invention are located between the first belt 113 and the second belt 123. Therefore, even if the sheet mediums are bent, the vertical-direction state of multiple stacked sheet mediums can be adjusted and limited by utilizing the elasticity of the belts, thereby ensuring reliable transportation.
As shown in
When the stacking mechanism 1 is in the stacking position, the motor gear 28 of the third motor rotates positively to drive the rack 29 engaged with the motor gear 28 to move upwards so that the paper baffle 27 moves upwards to block the downstream of the stacked mediums. When the stacking mechanism 1 is in the transport position, the third motor drives the motor gear 28 to rotate negatively to drive the rack 29 engaged with the motor gear to move downwards so that the paper baffle 27 moves downwards so the mediums can be sent out from the exit 53.
Specifically, the stacking mechanism 1 is hinged with the frame 5 via the core shaft 121a of the third belt pulley 121 of the lower ticket stacking assembly 12. The second switching mechanism 6 comprises an inner gear 61 and a second motor 62. The inner gear 61 is located at the outer side of the passage for transporting mediums and fixedly connected with the second bracket 124 of the lower ticket stacking assembly 12. The circle center of the inner gear 61 is coaxial with the core shaft 121a of the third belt pulley of the lower ticket stacking assembly 12. The second motor 62 is provided on the frame 5. The motor gear of the second motor 62 is in transmission connection with the inner gear 61 via a group of transition gears.
Since the inner gear 61 fixedly connected with the lower ticket stacking assembly 12 is in transmission connection with the second motor 62 via a group of transition gears, when the second motor 62 drives the inner gear 61 to rotate around the center of the second motor with a set angle, the lower ticket stacking assembly 12 can rotate with a set angle by taking the core shaft 121a of the third belt pulley are the circle center, and when the second motor 62 stops rotating and is self-locked, the position of the lower ticket stacking assembly 12 can be kept unchanged. Thus, the relative positions of the stacking mechanism 1 and the frame 5 can be changed thought the second switching mechanism 6 so as to set the discharge direction of the stacked mediums as required.
A working process for realizing recycling and processing of the sheet medium processing device according to the present embodiment will be explained below in combination with
As shown in
As shown in
It needs to be shown that the rotation angle of the stacking mechanism 1 may be set through the control of the second motor 62. The rotation angle of the stacking mechanism 1 can be adjusted so that the stacking mechanism 1 can transport mediums along different directions to transport the sheet mediums to different destinations such as the recycling box or an invalidated ticket box etc. as required.
In addition, the first belt 113 and the second belt 123 may be two or more narrow belts in parallel. At this moment, the paper baffle 27 may be located in a gap between the two narrow belts and extend into the space for stacking mediums between the first belt 113 and the second belt 123.
In addition, the parallel movement confining mechanism is not limited to a parallel four-rod mechanism as long as the parallel movement confining mechanism is able to limit the upper ticket stacking mechanism 11 to move parallelly from the lower ticket stacking mechanism 12.
When the first connecting rod 132a or the second connecting rod 132b are lifted around the hinge point, the parallel movement confining mechanism pushes the upper ticket stacking assembly 11 to move parallelly relative to the lower ticket stacking assembly 12 so that the upper ticket stacking assembly 11 and the lower ticket stacking assembly 12 are separated and a space for stacking mediums is formed therebetween.
When the first connecting rod 132a or the second connecting rod 132b descends, the first supporting rod 131a moves along the length direction of the first hopper chute 114a and the second supporting rod 131b moves along the length direction of the second hopper chute 124a, the upper ticket stacking assembly 11 contacts the lower ticket stacking assembly 12 to form a passage for transporting mediums therebetween under the action of the self-gravity of the upper ticket stacking assembly 11 or an external force. In the present embodiment, the first switching mechanism 2 may be a gear rack driving mechanism or a cam driving mechanism.
In other embodiments, the parallel movement confining mechanism may be a guide mechanism such as a guide groove or a guide pillar etc., so as to limit the moving trajectory of the upward parallel movement of the upper stacking assembly 11 relative to the lower ticket stacking assembly 12.
Above contents only describe the preferred embodiments of the present invention and are not intended to limit the present invention; for one skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
