This application claims the benefit under 35 U.S.C. §119 of Korean Patent Application No. 10-2014-0012552, filed Feb. 4, 2014, which is hereby incorporated by reference in its entirety.
BACKGROUND
The present disclosure relates to a medium processing apparatus and a financial device.
In general, financial devices are devices for processing financial business desired by customers. Financial devices may deposit/withdraw a medium or automatically transfer a medium. The financial devices comprise a medium processing apparatus for depositing or withdrawing a medium.
FIG. 1 is a view of a medium processing apparatus according to a prior art.
Referring to FIG. 1, a medium processing apparatus 1 according to the prior art comprises an stacking surface 6 on which a medium is stacked, first and second transfer rollers 2 and 4 for transferring a medium to be stacked onto the stacking surface 6, a stacking guide 5 for guiding stacking of the transferred medium, a damper 7 with which the medium passing through the first and second transfer rollers 2 and 4 collide, and a support guide 8 for supporting the stacked medium.
A sheet roller 3 for hitting the medium so that the transferred medium is stably stacked on the stacking surface 6 is connected to a rotation shaft 2A of the first transfer roller 2. The sheet roller 3 may comprise a plurality of contact parts 3A that are spaced apart from each other to hit the medium. That is, the sheet roller 3 comprises a body coupled to the rotation shaft 2A and the plurality of contact parts 3A extending from the body.
The plurality of contact parts 3A may radially extend from the sheet roller 3. For example, each of the plurality of contact parts 3A may be formed of a rubber material. A rotation trajectory of the contact part 3A of the sheet roller 3 is defined as shown by reference symbol 38.
To stack the medium, the medium passes between the first and second transfer rollers 2 and 4. The sheet roller 3 may rotate together with the first transfer roller 2 in a counterclockwise direction to allow the contact part to push the medium toward the damper while the medium passes between the first and second transfer rollers 2 and 4.
The medium passing between the first and second transfer rollers 2 and 4 may ascend along the stacking guide 5 to collide with a bottom surface of the damper 7 as shown by reference A. Then, the medium colliding with the bottom surface of the damper 7 may be deformed as shown by reference B.
The deformed medium may be recovered while moving downward by the self-weight thereof as shown by reference C. Here, the contact part of the sheet roller 3 rotating in the counterclockwise direction may hit the medium. The hit medium may collide with the stacking surface 6 in a state where a lower end of the medium is unfolded as shown by reference D and then be supported by the support guide 8 as shown by reference E.
Here, the first transfer roller 2 and the body of the sheet roller 3 as well as the rotation shaft 2A may be disposed under the stacking surface 6. Therefore, the contact part 3A has to have a long length to hit the medium. Thus, the contact part 3A may collide with peripheral parts of the sheet roller while the sheet roller 3 rotates to reduce the lifespan of the sheet roller 3 due to abrasion of the sheet roller 3 and cause a lot of noises.

The transfer path 19 may comprise a first path 191 and second path 192, which are connected to the medium entrance part 13.
FIG. 4 is a schematic view of a medium processing apparatus according to an embodiment, and FIG. 5 is a view of a stopper for preventing a medium from being inserted between the rotation shaft and the support guide.
Referring to FIGS. 4 and 5, the medium processing apparatus 100 according to an embodiment may stack a medium for withdrawing or a medium that is returned.
The medium processing apparatus 100 may comprise an stacking surface 170 on which the medium is stacked, first and second transfer rollers (feed and gate rollers) 110 and 120 for transferring the medium to be stacked on the stacking surface 170, sheet rollers 112 and 113 for hitting the medium to stack the medium, a stacking guide 140 for guiding stacking of the transferred medium, a damper 150 to which the medium passing between the first and second transfer rollers 110 and 120 collide, and a support guide 160 for supporting the stacked medium.
The support guide 160 may receive a power of a driving source that is not illustrated to move in a left/right direction in FIG. 4. Thus, when number of the medium stacked on the stacking surface 170 increases, the support guide 160 may move in a left direction in FIG. 4.
The sheet rollers 112 and 113 may comprise a body part 112 connected to a rotation shaft 111 and a plurality of contact parts 113 extending from the body part 112. Also, the first transfer roller 110 may be connected to the rotation shaft 111. Thus, the sheet rollers 112 and 113 may rotate together with the first transfer roller 110 by rotation of the rotation shaft 111.
The plurality of contact parts 113 may radially extend from the body part 112 and be spaced apart from each other. For example, each of the plurality of contact parts 113 may be formed of a rubber material. A rotation trajectory of the contact part 113 may be defined as reference number 114.
In the current embodiment, to minimize noises generated when the sheet rollers 112 and 113 rotate by reducing a length of the contact part 113, at least one portion of the rotation shaft 111 may be disposed at a position above the stacking surface 170.
Since at least one portion of the rotation shaft 111 is disposed above the stacking surface 170, at least one portion of the first transfer roller 110 and at least one portion of the sheet rollers 112 and 113, which are coupled to the rotation shaft 111, may be disposed above the stacking surface 170.
Also, a portion or whole of the second transfer roller 120 may be disposed above the stacking surface 170, In FIG. 4, for example, a whole of the rotation shaft 111 and a whole of the second transfer roller 120 are disposed above the stacking surface 170.
Here, since the medium has to pass between the first transfer roller 110 and the second transfer roller 120, of which at least one portion is disposed above the stacking surface 170, at least one of a guide 130 for transferring the medium may be disposed above the stacking surface 170. Here, the guide 130 may guide the medium independently or together with the stacking guide 140 toward the first and second transfer rollers 110 and 120.
A distance between the damper 150 and the stacking surface 170 in a direction parallel to a transfer direction of the medium may be greater than the sum of a height of the tallest medium and a radius of the first transfer roller 110. Also, a minimum distance between a center of the rotation shaft 111 and the damper 150 in a direction parallel to the transfer direction of the medium may be greater than the sum of the radius of the first transfer roller 110 and the height of the tallest medium.
Also, a distance between the damper 150 and the stacking surface 170 may be greater than the sum of a height of the shortest medium and the length of the contact part 113. Also, the contact part 113 may have a length less than a diameter of the first transfer roller 110.
Thus, it may prevent the medium colliding with the damper 150 from contacting the first transfer roller 110. In the present disclosure, the medium may comprise a first side having a relatively large length and a second side having a length shorter than that of the first side and perpendicular to the first side. For example, the height of the medium may be the length of the second side of the medium. Of course, the height of the medium may be the first side depending on the transfer direction of the medium.
Also, a distance between the damper 150 and the stacking surface 170 in a direction parallel to the transfer direction of the medium may be greater than that between each of contact points on which the first and second transfer rollers 110 and 120 contact the medium and the damper 150.
The medium processing apparatus 100 may further comprise stoppers 162 and 164. The stoppers 162 and 164 may prevent the medium from being jammed in a space between the rotation shaft 111 and the support guide 160. The stoppers 162 and 164 may further comprise a support part 162 fixed to the stacking surface 170 and an extension part 164 extending from the support part 162. The extension part 164 may shield at least one portion of the space between the rotation shaft 111 and the support guide 160. The extension part 164 may comprise a first portion 165 bent from the support part 162 and a second portion 166 bent from the first portion 165.
At least one portion of the extension part 164 may be disposed above the rotation shaft 111. Also, the extension part 164 may extend toward an upper portion of the rotation shaft 111. For example, at least a portion of the second portion 166 may overlap the rotation shaft 111 in an up and down direction.
Since the medium contacts the stoppers 162 and 164 even though the sheet rollers 112 and 113 pulls the medium while the sheet rollers 112 and 113 rotate, it may prevent the medium from being inserted between the rotation shaft 111 and the support guide 160.
Hereinafter, an operation of the medium processing apparatus according to the current embodiment will be described.
The medium is transferred along the transfer path 19 and stacked. The medium transferred along the transfer path 19 may pass between the first and second transfer rollers 110 and 120 to collide with the damper 150 as shown by reference A. The medium colliding with the damper 150 may be deformed as shown by reference B. Also, the medium may move downward and thus be spaced apart from the damper 150 as shown by reference C to allow the contact part 113 of the sheet rollers 112 and 113 rotating in a counterclockwise direction in FIG. 4 to hit the medium as shown by reference C.
Here, since a distance between the damper 150 and the stacking surface 170 in a direction parallel to the transfer direction of the medium is greater than that between each of the contact points on which the medium contacts the first and second transfer rollers 110 and 120 and the damper 150, a distance between each of contact points on which the medium completely passes between the first transfer roller 110 and the second transfer roller 120 and a spot on which the medium collides with the damper 150 may be reduced.
Thus, the medium may be reduced in deformation in a state where the medium collides with the damper 150. If the deformation of the medium colliding with the damper 150 is large, a straight length of the deformed medium is less than a distance between the damper 150 and the contact part 113 of the sheet roller 112. Thus, the contact part 113 may not hit the medium to allow the medium to be poorly stacked.
However, in the current embodiment, since the medium colliding with the damper is reduced in deformation, the contact part 113 may hit the medium even though the contact part 113 of the sheet rollers 112 and 113 is reduced in length. Here, the contact part 113 may hit the medium when the medium is in a state as shown by reference B or c.
The medium hit by the contact part 113 may be reduced in deformation as shown by reference D and finally supported by the support guide 160 in a state where the medium is stacked on the stacking surface 170 as shown by reference E.
According to the current embodiment, the medium colliding with the damper is reduced in deformation, and thus the poor staking of the medium may be prevented. Also, since the contact part of the sheet roller has a length less than that of the contact part of the sheet roller when the rotation shaft is disposed under the stacking surface, the abrasion of the contact part may be prevented. Also, noises generated while the sheet roller rotates may be minimized.
FIG. 6 is a view of a medium processing apparatus according to another embodiment.
A medium processing apparatus according to the current embodiment has the same constitutions as those of the foregoing embodiments, however, the position of a rotation shaft is different from that in the foregoing embodiments. Thus, only specific portions of the current embodiment will be described below.
Referring to FIG. 6, in the medium processing apparatus according to the current embodiment, the stacking guide 140 may move toward the support guide 160 and move in a direction far away from the support guide 160. When the stacking guide 140 moves toward the support guide 160, the rotation shaft 111 of the sheet rollers 112 and 113 may be disposed under a stacking surface 171 to prevent interference between the stacking guide 140 and the rotation shaft 111 of the sheet rollers 112 and 113. Also, a portion of the first transfer roller 110 coupled to the rotation shaft 111 may be disposed above the stacking surface 171. Also, a portion of the sheet rollers 112 and 113 may be disposed above the stacking surface 171 according to a position of the rotation shaft 111.
Thus, the stacking guide 140 may move toward the support guide 160 without interfering with the rotation shaft 111 to press the medium stacked on the stacking surface 171 toward the support guide 160.
Here, a hole or a cutoff part may be defined in a lower side of the stacking guide 140 to prevent interference between the stacking guide 140 and the first transfer roller 110 and the sheet rollers 112 and 113, which are disposed above the stacking surface 171, from occurring while the stacking guide 140 moves toward the support guide 160.
