Description

[Detailed explanation of the idea] [Technical field to which the idea belongs]

This idea was developed in a device that handles banknotes, such as a vending machine or an automatic money changer, in which the banknotes that have been conveyed are stored and the stored banknotes are also used for dispensing. The present invention relates to a mechanism for later regulating banknotes to a predetermined storage position, that is, a banknote position adjustment mechanism in a banknote storage/dispensing device.

[Prior art and its problems]

In conventional vending machines and automatic currency exchange machines, the banknotes that were inserted into the machine were simply stored there. However, recent market needs are such that the stored banknotes are also used for dispensing. In other words,
In the case of a vending machine, it is used as change, and in the case of an automatic currency exchange machine, it is also used as banknotes to be exchanged. In other words, it recycles banknotes. If the banknotes are simply stored, there is no problem even if the storage positions of the banknotes are slightly uneven, but the problem is that the unevenness causes malfunctions in the dispensing operation. Banknotes are inherently delicate to handle, but variations in their position increase the risk of problems such as them not working as expected or getting stuck in related mechanisms. Moreover, in the case of a banknote storage/dispensing device, especially when dispensing, stacked banknotes are sequentially paid out from the front side of the banknotes, but the second and subsequent banknotes are displaced by the banknotes on the front side. When the dispensing operation is completed, it is necessary to return the misaligned banknotes to their original positions. On the other hand, technically, various methods can be considered as means for regulating the position. However, the challenge is to achieve simple structure and reliable operation within a small space. As mentioned above, since the market needs themselves are relatively new, there is currently nothing that satisfies them.

[Purpose of the invention]

The purpose of this invention was to solve the problems of the conventional ones, to regulate the storing position of banknotes to a preset position, and to make it possible to respond immediately when a request for dispensing is received. Our goal is to provide products with a unique structure and high reliability.

[Key points of the idea]

The main points of this invention to achieve the above objectives are:
In the case of storing banknotes, a mechanical position regulating lever is installed at a predetermined position, and in the case of dispensing, this position regulating lever is moved to ensure that there is no problem with dispensing, and returns to the predetermined position after dispensing. The position of the banknote is regulated by the movement. Moreover, the movement of the position regulating lever is performed using the operation of a separate member essential for bill dispensing. That is, when dispensing a bill, the bill feeding roller, which has been floating above the bill surface, is brought into contact with the bill surface, and the bill is fed out by the frictional force between the two. The movement of the holding frame of the banknote feeding roller for this contact operation pushes and rotates a part of the position regulating lever that is rotatably supported around an appropriate axis. This rotation causes
To move the surface of a position regulation lever that used to regulate banknotes to a position that does not interfere with the dispensing of banknotes. When returning the banknote regulating surface of this position regulating lever to its original position, a path is taken so that the stacked banknotes with protruding end faces can be pushed back.

[Example of idea]

An embodiment of this invention will be described with reference to FIGS. 1 to 3. Fig. 1 shows a front view of the embodiment, Fig. 2 shows a side view of the embodiment as seen from the direction of arrow A, and Fig. 3 shows a side view of the embodiment as seen from another direction of arrow B. . First, the configuration of this mechanism will be explained. In FIG. 2, as will be described later, the banknotes 10 are sequentially stacked and stored on a storage bottom plate 19.
Reference numeral 1 denotes a storage position regulating lever, 2 a rotating shaft for rotatably supporting the position regulating lever 1, and 3 a rotating shaft having one end attached to a fixed frame 30 and the other end attached to the position regulating lever 1. A spring 4 is a push shaft fixed to a holding frame 11A of a bill dispensing roller unit 11 to be described later, and 12 is a roller for dispensing bills, which is provided with a rubber uneven part on a part of its circumference. . Reference numerals 13 and 14 are a well-known set of rollers for preventing multiple bills from passing through. The upper roller 13 for preventing the passage of multiple sheets has three thin discs arranged at a certain interval in the axial direction. Also, in the lower one 14, two disks having a smaller diameter than the above disks are arranged between the above disks. The outer peripheries of both disks are placed so that they touch each other with a slight spacing between them. This interval is adjustable, and how to choose this interval is a matter of know-how. Also, usually the larger disk is made of a metal material, and the smaller disk is made of a softer material at least on its outer periphery. The upper multiple sheet passage prevention roller 13 is connected to the drive shaft 1
8, and the feeding roller 1
2 in the same direction and so as to equalize the linear velocity at the outer periphery. Further, the lower multiple sheet passage prevention roller 14 cannot rotate in the dispensing direction.
A one-way clutch is built in so that it can rotate in the opposite direction. A frame 11A that mainly holds the feeding roller 12 and the plural bill passage prevention roller 13 constitutes the bill feeding roller unit 11. The drive shaft 18 rotates only clockwise in the figure. The holding frame 11A of the bill feeding roller unit 11 is rotatably supported coaxially with the drive shaft 18. Further, an operating lever 15 is fixed to the holding frame 11A, and this operating lever 15 is connected to a movable portion of an electromagnetic actuator 16. Further, a spring 17 is attached to the holding frame 11A to apply a force to rotate it counterclockwise, and a stopper 17A is provided in response to this force. Note that FIG. 1 shows the arrangement of each of the above members viewed from the front, so that the relative positions thereof can be understood. That is, there are three sets of banknote feeding rollers 12 and two sets of multiple banknote passage prevention rollers 13 and 14.
2 and are arranged alternately in the axial direction. Next, for the sake of convenience, the operation of this mechanism will be explained separately for the case of storing banknotes and the case of dispensing banknotes. First, in the case of banknote storage, the solid line in FIG. 2 corresponds to the case. That is, the outer circumferential surface of the bill feeding roller 12 is separated from the surface of the stored bill 10. At the same time, the storage position regulation lever 1 is also in a position indicated by a solid line and a partially broken line, and the regulation surface 1a at the tip thereof blocks the front side of the banknote 10 (left side in the figure). Next, when a command to pay out banknotes is issued, the movable part of the electromagnetic actuator 16 operates upward based on the command signal, and via the operating lever 15,
The holding frame 11A is rotated clockwise around the drive shaft 18. At the same time, the push shaft 4 fixed to the holding frame 11A pushes the upper edge (engaging part) of the storage position regulating lever 1, and the lever 1 rotates clockwise as shown by the double arrow R. to move to the position indicated by the one-dot chain line in the figure. At the same time, the outer peripheral surface of the bill feeding roller 12 comes into contact with the surface of the bill 10. In the above state, the bill feeding roller 12 is rotated by the rotation of the drive shaft 18, and the bill passing prevention roller 1 is rotated.
3, the stored banknotes are sequentially fed out one by one. Then, a plurality of the fed bills pass through prevention rollers 13 and 1.
The set of 4 ensures that each sheet passes through one by one. In other words, even if two banknotes try to pass through the gap between the multiple-sheet passage prevention rollers 13 and 14, the lower banknote will separate from the upper banknote due to the large friction with the rubber surface of the roller 14. It ends up staying in that spot. The banknotes that have passed through these are sent out through between a sending out roller 26 and a pressing roller 27 installed opposite to the sending out roller 26 shown in FIG. Naturally, the drive shaft 18 is instructed to rotate at a speed corresponding to the number of coins to be paid out, and
The electromagnetic actuator 16 performs a suction operation only during the dispensing period. When the dispensing command is completed, the operation of the electromagnetic actuator 16 is canceled and the operating lever 15 returns to the position shown by the solid line. In other words, the bill feeding roller unit 11 also returns to the solid line display position. Then, the push shaft 4 moves from the position indicated by the dashed line to the position indicated by diagonal lines. At the same time as this movement, the storage position regulating lever 1 is moved by the push shaft 4 by the spring 3.
It rotates counterclockwise to the position where it hits and returns to its original position (the position shown by diagonal lines). If there is a banknote stuck at the multiple sheet passage prevention roller, it is pushed back to the normal storage position by the return operation of the storage position regulation lever 1. In this way, it becomes possible to store banknotes.

[Effect of the invention] When storing banknotes (at the time of storage), the position regulating lever is set at a predetermined position (a position where it contacts the end of the stored banknote in the storage section) to prevent the movement of banknotes. In the case of dispensing banknotes (at the time of dispensing), the position regulation lever can be made to take two stable position states so that the position regulation lever moves to a position where there is no problem in dispensing banknotes. Thereby, it is possible to realize a banknote position regulating mechanism suitable for use in a banknote storage/dispensing device, which allows banknotes to be stacked and stored in an orderly manner and causes no hindrance to dispensing. Even if there is a banknote stuck in a protruding state on the side of the passage prevention roller when dispensing is completed, the regulating surface of the position regulating lever will move the bill to the normal storage position when moving from dispensing to storage. Since the paper is pushed back, it is possible to prevent troubles such as inability to dispense or jamming of paper money, and to improve reliability. The bill storage/dispensing device utilizes the movement of the dispensing roller holding frame, which is an essential component of the dispensing mechanism, to cause the position regulating lever to perform the opening and returning operations. It is also simple and has great effects in terms of space and cost.
