Abstract

PURPOSE:To smoothly accommodate paper sheets free from the mutual interference even if the transport interval for the paper sheets is reduced, by turning a downstream side roller and a vane wheel at a higher speed than that of a paper sheet transport passage, paper sheet flow passage and an upstream side roller and installing a unidirectional clutch on the upstream side roller, at the same time. CONSTITUTION:During the time when a paper money B1 sent from the first paper money flow passage 11 side, shifts into its horizontal posture from its vertical posture by means of a blade wheel 14, a paper money B2 is sent into a blade wheel 24 through a flow passage 21 from the second paper money flow passage 21. When the blade wheel 24 turns, the succeeding paper money B2 sometimes interferes with the preceding paper money B1. However, when the paper money B1 is engaged with a downstream side roller 13, the feeding speed is increased, and the paper money B1 is speedily sent into the blade wheel 14. Since the rotational speed of the blade wheel 14 is made high, the paper money B1 is set nearly horizontal, during the time when the paper money B2 arrives at the blade wheel 24 through feeding rollers 22 and 23 from the flow passage 21, and the trouble of interference between both paper moneys is prevented. Accordingly, the interval between the paper moneys transported into a paper money transport passage 2 can be reduced.

Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a paper sheet that is attached to a bill depositing device or the like and is provided for storing paper sheets conveyed through the device in a paper sheet storage section with their front and back sides aligned. This invention relates to a storage device for aligning the front and back sides of leaves. [Prior art 1] For example, financial institutions and the like are equipped with bill depositing devices to automate their deposit processing, and these bill depositing devices are equipped with a hopper for inserting bills into the hopper. After the banknotes are discriminated while being transported, they are stored in a banknote storage unit such as a stacker. Here, the front and back sides of the banknotes thrown into the hopper are not necessarily arranged, and when such banknotes with uneven front and back sides are stored in the banknote storage section, it is required that the front and back sides are aligned. For this purpose, the banknote depositing device is provided with a storage device for aligning the front and back sides of banknotes. For example, the storage device for aligning the front and back sides of banknotes is provided at one side of the banknote storage section at the exit portion of the banknotes in the banknote conveyance path. A first banknote flow path for introducing banknotes into the inside from the banknote, and a second banknote flow path for introducing banknotes into the banknote storage section from the opposite direction to the first banknote flow path,
Conventionally, devices have been used that are configured to include a path switching means that switches the outlet between the first banknote flow path and the second banknote flow path depending on the front and back sides of the banknotes conveyed by the banknote conveyance path. ing. And this first one. A feed roller that guides the banknotes coming out of each banknote flow path so as to face directly downward in order to stabilize the posture of the banknotes when feeding the banknotes from the second banknote flow path to the banknote storage unit; An impeller is provided to horizontally change the direction of banknotes sent out in the vertical direction from the feed roller, and these impellers are configured to rotate in mutually opposite directions.

[Problem to be solved by the invention]

In the bill depositing device, authenticity, denomination 9, front and back, etc. are determined at a position along the conveyance path of the bill, and the number of bills is counted. Therefore, in order to make this discrimination and counting more efficient, it is necessary to make the interval between banknotes conveyed along the conveyance path as narrow as possible, and to increase the number of banknotes distributed along the conveyance path. However, if the feeding interval of banknotes is made too narrow, the banknotes fed into the impeller through the banknote flow path on the back side will pass through the banknotes on the other side until the impeller rotates and moves to a horizontal state. The banknotes are fed into the impeller from the banknote flow path and the banknotes begin to change direction. As a result, the banknotes on both sides may interfere with each other, making it difficult to maintain a normal posture. For this reason, in the past, in order to prevent the bills fed into the bill storage section from interfering with each other, a certain amount of space was maintained between the bills being conveyed, which resulted in poor efficiency in identifying and counting bills. There was a drawback. The present invention has been made in view of the above-mentioned points, and an object of the present invention is to smoothly store sheets in a sheet storage section without interfering with each other even if the conveyance interval of sheets is narrowed. To provide a storage device for paper sheets that can align the front and back sides of paper sheets.

[Means for Solving the Problems l] In order to achieve the above-mentioned object, the present invention provides first and second
Of the pair of feed rollers interposed between the paper flow path and the impeller in the paper sheet transport path 9, the downstream roller and the impeller are rotated at a higher speed than the paper sheet flow path and the upstream roller. The invention is characterized in that the upstream roller is provided with a one-way clutch that allows the upstream roller to freely rotate in the rotational direction. [Function] With this configuration, a plurality of sheets are conveyed in a paper sheet conveyance path with their front and back sides at random, and the paper sheets are discriminated before they reach the exit section of this sheet conveyance path. The front and back sides of the conveyed paper sheet are determined by an appropriate determination means such as a paper sheet. When the sheet whose front and back sides are determined to be one side reaches the outlet of the sheet transport path, the path switching means is activated to transport the sheet toward, for example, the first sheet flow path, The paper is fed from the first paper flow path through a feed roller and an impeller from one side of the paper storage section. Furthermore, when a sheet whose front and back sides are determined to be opposite to those described above reaches the exit section, the path switching means is activated to change the path to the second path.
The side opposite to the paper sheet that is switched to the sheet flow path side of the second sheet flow path and is transported from the second sheet flow path through the feed roller and the impeller and through the first sheet flow path described above. It is stored in the paper sheet storage section. By storing the paper sheets in the paper sheet storage section from opposing directions depending on their front and back orientations, the paper sheets can be stored in the paper sheet storage section with their front and back sides aligned. . Here, 1. For example, when a sheet is sent out from the first sheet flow path to the feed roller and engages with the downstream roller, the feeding speed of this sheet is increased and the sheet is sent to the impeller at high speed, Moreover, since this impeller/root wheel also rotates at high speed, the paper is quickly guided into the paper storage section. Therefore, even if the next sheet to be fed is directed to the path that passes through the second sheet flow path, by the time this subsequent sheet passes through the feed roller and reaches the impeller, the preceding sheet has been removed. The impeller has already displaced the sheets into a nearly horizontal state, and there is no interference between the sheets being sent forward and backward. Here, when a sheet of paper is engaged with the downstream roller, the sheet of paper is also engaged with the upstream roller, but the upstream roller is provided with a one-way clutch that rotates freely in the rotation direction. Because of this, when a sheet of paper engages with the downstream roller, the upstream roller follows suit and rotates at high speed, so there is no problem such as tensile force acting on the sheet of paper and causing damage. . As a result, it becomes possible to shorten the interval between sheets sent along the transport path. Therefore, the efficiency and speed of processing such as discrimination and counting can be increased.

Embodiments of the present invention will be described below in detail with reference to the drawings.In this embodiment, a device configured as a storage device for aligning the front and back sides of banknotes installed in a banknote deposit processing device is shown. First, in FIG. 2, reference numeral 1 indicates a hopper into which banknotes are thrown, and the banknotes thrown into the hopper 1 are transported by a banknote conveyance path 2 consisting of a conveyor or the like. The truth or falsity of The banknotes are stored in a stacker 4 that stores the banknotes after passing through a discrimination section 3 that determines the front and back of the denomination 1, the presence or absence of damage, and the like. In order to align the front and back sides of the banknotes transported along the banknote transport path 2 and store them in the stacker 4, a front and back alignment mechanism 10 is provided between the banknote transport path 2 and the stacker 4.
will be provided. As shown in FIG. 1, this front-back aligning mechanism 10 is attached to an exit portion 2a of the banknote conveyance path 2 to the stacker 4. The front and back aligning mechanism 10 includes a first conveyor belt connected to an exit portion 2a of the banknote conveyance path 2. The second banknote flow path 11.21 and each paper rectification flow path 11
．． At the exit portion of 21, there are feed rollers 12.13 and 22.23, each consisting of a pair of vertically arranged feed rollers 12.13 and 22.23, and an impeller 14.2.
It consists of 4. Among these feed rollers, the feed roller 12.22 is an upstream roller located on the connection side of the banknote flow path 11.21, and the feed roller 13.23 is an upstream roller located on the connection side of the banknote flow path 11.21.
The upstream roller 12.22 and the downstream roller 13.23 are arranged in a row in a perpendicular direction, respectively. Each of the above-mentioned feed rollers consists of a driving roller and a pressing roller, and by rotationally driving the driving roller, the pressing roller follows and rotates, and these driving rollers and pressing rollers are rotated. Since the banknote is of a well-known structure in which the banknote is held between the rollers and conveyed by the rotation of the banknote, illustration of its specific structure is omitted. In the drawings, the driving rollers of each of the feed rollers 12, 13, 22 and 23 are given the suffix raJ, and the pressing rollers are given the suffix rbJ. Further, the impellers 14, 24 are constructed by installing a large number of springy blades 14b, 24b each having an F-shaped cross section on the rotating drums 14a, 24a. Further, the transport route of the banknotes transported through the banknote transport path 2 is the first banknote flow path 11 and the second banknote flow path 21 described above.
A shutter 30 is provided as a path switching means 0 for switching between. This shutter 30 is rotatable around a rotation shaft 31,
When the position is shown by the solid line in FIG. 1, the banknotes conveyed through the banknote conveyance path 2 are guided to the first banknote flow path 11, and when the position is switched to the position shown by the imaginary line, the banknote is guided to the first banknote flow path 11. , and is configured to be guided toward the second banknote flow path 21. Therefore, when the banknotes being conveyed along the banknote conveyance path 2 are in a state where the front side faces upward, the shutter 30
is at the position indicated by the solid line in FIG. , 14b, the banknotes are displaced horizontally by the rotation of the impeller 14, and placed in the stacker 4.
stored inside. In addition, when the back surface is facing upward, the shutter 30 is displaced to the position shown by the imaginary line in FIG. The blades 24b, 2 of the impeller 24 are guided in the vertical direction by passing through the blades 24b and 23.
4b, and is housed in the stacker 4 in a horizontal position with its surface facing upward. Here, when the banknotes passing through the path via the first banknote flow path 11 and the banknotes passing through the path through the second banknote flow path 21 are respectively displaced from a vertical state to a horizontal state by the impeller 14.24. In addition, they must ensure that they do not interfere with each other. Therefore, compared to the normal bill feeding speed (for example, about 600 sheets per minute) in the bill conveyance path 2, the feeding speed of the bill to the impeller 14.24 and the impeller 14.2
The rotational speed of No. 4 is increased to about twice that of the previous one. In this case, not only the rotational speed of the impeller 14.24 is made twice the feeding speed of the banknotes in the banknote conveyance path 2, but also the speed at which the banknotes are fed into the impeller 14.24 is increased. The speed must be increased by 1 2 to follow the rotational speed. Therefore, of the pair of feed rollers 12.13 and 22.23, the downstream roller 13.23 located on the downstream side in the banknote transport direction is rotated in synchronization with the impeller 14.24. do. On the other hand, the upstream rollers 12.22 are connected to the banknote conveyance path 2 and the first. Speed control is performed so that the banknotes are conveyed at the same speed as the second banknote flow path 11.21. The drive rollers 12a, 22a of the upstream rollers 12.22 are driven by a one-way clutch 40.40 that rotates freely in the direction of rotation.
It is connected to the drive means via. Further, the downstream roller 13.23 and the first. The exit portion of the second banknote flow path 11.21 is spaced apart by approximately the width of one banknote. This embodiment is constructed as described above, and its operation will be explained next. First, in the deposit device, a plurality of banknotes are placed in the hopper 1.
When the inserted banknotes are inserted with their front and back sides randomly, they are conveyed by the banknote conveyance path 2 and sent to the discrimination section 3.
Its authenticity and denomination. The front and back sides, presence or absence of damage, and other aspects are identified. When this banknote is conveyed to the exit part 2a of the banknote conveyance path 2, the shutter 30 is activated and the banknote flow path in either the first or second banknote flow path in the front and back aligning mechanism 10 is activated depending on the front and back sides of the banknote. It will lead you to 11 or 12. For example, as shown in FIG. 3, when the first banknote B■ is conveyed in the banknote conveyance path 2 with the upper side in the figure facing up, the discriminating unit 3 Based on the signals regarding the front and back sides from the shutter 30, the shutter 30 moves to the solid line position in FIG. It is held between the blades 14a and fed into the stacker 4 from the left side in the figure. As a result, the banknotes are stored in the stacker 4 with the front side facing upward. 3 4 On the other hand, the next banknote B■ is the same as the preceding banknote B
Contrary to (2), when the lower side in the figure is the front side of the banknote conveyance path 2, the shutter 30 is switched to the position indicated by the dashed-dotted line in FIG. 1 based on the signal from the discrimination section 3. , the banknotes B■ are fed into the second banknote flow path 21 side, and are sent from the right side of the stacker 4 through the feed rollers 22, 23 and the impeller 14. For example, while the banknote B■ fed from the first banknote flow path 11 side is displaced from the vertical state to the horizontal state by the impeller 14, the banknote B■ is transferred from the second banknote flow path 21 to the second banknote flow path 21. The banknotes are fed into the impeller 24 through the banknote flow path 21,
When the impeller 24 rotates, the following banknote B2 may interfere with the preceding banknote B2. However, banknote B
When (1) engages with the downstream roller 13, its feeding speed is increased and it is quickly fed into the impeller 14. Moreover, since the rotational speed of this impeller 14 is also fast, by the time the banknote B■ reaches the impeller 24 from the second banknote flow path 21 via the feed rollers 22 and 23,
The banknotes B■ are in a substantially horizontal state, and there is no fear that the yen banknotes will interfere with each other. For this reason, it becomes possible to narrow the interval between banknotes conveyed to the banknote conveyance path 2.
It is possible to improve the efficiency and speed of processing such as counting. Here, the banknote B is transported at the same speed as the transport speed in the banknote transport path 2 until it engages with the downstream roller 13, and the speed is increased when it engages with the downstream roller 13. become. At this time, the banknote B■ is already in the first
The banknote remains connected to the upstream roller 12 until the banknote separates from the banknote flow path 11 or is fed by a predetermined amount. However, since the driving roller 12a of the upstream roller 12 is connected to the driving means via the one-way clutch 40, the upstream roller 12 rotates following the rotational speed of the downstream roller 13, and the banknotes Excessive to B■
5 6 There will be no inconvenience such as damage caused by tensile force. Also, when the banknote B is sent from the second banknote flow path 21 to the impeller 24 via the feed rollers 22 and 23, the upstream roller 22 similarly follows the downstream roller 23 by the one-way clutch 40. It will be forced to rotate. In the above-mentioned embodiment, the storage device for aligning the front and back sides of paper sheets was shown as a storage device for aligning the front and back sides of paper sheets, which is built in a banknote depositing device. It is also possible to store paper sheets with their front and back sides aligned.

【Effect of the invention】

As described in detail above, the present invention provides first and second paper flow paths selected by a path switching means at the exit portion of a paper sheet conveyance path, and also provides a pair of feed rollers and an impeller, respectively. In addition, the paper sheet conveyance path 9, which is a downstream roller and an impeller, is rotated at a higher speed than the sheet flow path and the upstream roller, and a one-way clutch is provided to allow the upstream roller to rotate freely in its rotation direction. This makes it possible to feed the paper sheets into the paper storage section with the front and back sides aligned, and even if the conveyance interval of the paper sheets is narrowed to some extent, there will be no difference between the sheets when storing them in the paper storage section. Since there is no possibility that paper sheets introduced from opposite directions will interfere with each other, various effects such as the efficiency of processing such as paper discrimination and counting can be achieved.
