[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is applied to an automatic device for automatically processing coins such as a vending machine or a vending machine, which can return change for surplus money to a user or accept foreign matter or fake The present invention relates to a coin processing device having a return function such as returning a received item to a user when an abnormal condition such as non-denomination occurs.

[0002]

[Prior art]

 As a conventional example, a coin processing device built into an automatic ticket vending machine installed in a station will be described. Such a coin processing device is, for example, as disclosed in Japanese Utility Model Publication No. 59-18532 and Japanese Patent Publication No. 5-2674, confirmed by a coin discriminating mechanism for determining authenticity and denomination of inserted coins and a coin discriminating mechanism. A sorting mechanism that sorts the genuine coins that have been sorted into denominations and sorts them into a sorting passage that is specified in advance for each denomination, and a coin holding mechanism for each denomination that is arranged at the end of each sorting passage of the sorting mechanism. Further, it is provided with a coin container of a coin type arranged corresponding to a coin holding mechanism of a coin type. The coin transport system for finally storing the coins inserted into the coin slot uses the self-weight drop of the inserted coins in order to simplify the mechanism of the coin processing device. There is. That is, the coin slot for the user to insert coins is arranged in the upper part of the panel of the automatic ticket vending machine, and the safe container is arranged at the lowest position of the device, and the downward inclined passage and gravity connected to this coin slot are used. A simple transfer mechanism that can drop and transfer coins by its own weight has been adopted by sequentially connecting the above-mentioned mechanisms along a hanging path in each direction.

Furthermore, in order to deal with the case where fake coins or surplus coins are input, or when it is necessary to return change, a return mechanism for automatically returning these to the user is provided. . Such a return mechanism includes a belt conveyor arranged at a position lower than the coin holding mechanism and a return tray provided at the carry-out end of the belt conveyor. Then, for example, when the user presses the cancel button, the coin holding mechanism discharges all the coins temporarily stored until now to the belt conveyor side (discharge by dropping), and the coin is transferred via the belt conveyor. For example, the change is returned to the return tray, or the change is dropped from the change mechanism (change hopper) located higher than the belt conveyor to the belt conveyor, and the change is returned to the return tray via the belt conveyor. Was being processed.

However, as a result of adopting such a transport mechanism, the above-mentioned respective mechanisms are inevitably arranged vertically, so that the vertical height of the coin processing device becomes high and the above-mentioned coin slot is the highest. Since the return mechanism including the belt conveyor and the return tray is located at the lowest position, there was a problem that the height difference between the coin slot and the return tray was extremely large. For example, if an automatic ticket vending machine is installed in the station yard so that the coin slot is low, considering the convenience of children such as children, the return tray will be in an extremely low position. Therefore, it would be irrational for an adult customer to reach the return tray without bending over, and conversely, place the return tray at a relatively high position to suit the adult customer. If they are arranged, the coin slot will be at a very high position, which will cause a problem that children cannot reach the coin slot.

Therefore, in order to solve such a problem, a coin processing device has been developed which is newly provided with a return mechanism for making the heights of the coin inlet and the return tray about the same (actual Kaihei 3). -21174). This new return mechanism sandwiches the first belt conveyor, which is located at a lower position than the above change mechanism and coin holding mechanism, and the return coins conveyed by this first belt conveyor, between the opposing belts. It is also configured to be conveyed upwards and to be carried out to the return tray provided at the upper position. Therefore, even if the overall height of the coin processing device remains high, the entire coin processing device should be placed at an appropriate low position so that the coin slot and the return tray can be easily used by children and adults. Since it can be set, the convenience of the user can be greatly improved, and the simple transfer mechanism that realizes the transfer by dropping the inserted coin by its own weight can be adopted as before. ing.

[0006]

[Problems to be solved by the device]

 However, in the coin processing device that adopts such a new return mechanism, as described above, first, the first belt conveyor conveys the returned coins in a substantially horizontal direction, and then in the conveyance direction from the middle. However, the mechanism is complicated because it is transferred upward and is sandwiched between the opposing belts, resulting in a new problem such as a delay in the return mechanism for returned coins.

Further, to describe a concrete example of this delay phenomenon and the like, the coin holding mechanism described above, in the normal case, when the user (the customer) starts to insert coins, a plurality of genuine coins are sequentially transferred. After the user (A) presses the instruction button for designating the boarding section, the savings process continues until the next user (B) inserts a new coin. Transfers all specie coins to the change hopper and promptly starts the deposit of specie coins for the next user (B). In other words, by saving the coins of the previous user (A) as much as possible, it is possible to prevent unnecessary trouble in case of complaint from the user. On the other hand, if cancellation processing is instructed, for example, if the user (A) continuously inserts multiple coins and then realizes that the vending machine cannot purchase the desired item, the coin holding mechanism is While storing genuine coins, when the push of the cancel button is detected, all the stored coins are returned by dropping and discharging them on the first belt conveyor of the return mechanism. In this way, the coin deposit mechanism is provided to perform a so-called buffer function for making a rational and reliable commercial transaction by determining for each customer a fake coin or a foreign substance.

However, when the above process occurs, the coin holding mechanism drops and discharges a plurality of coins, which have been stored up to now, to the first belt conveyor stopped at one time, A plurality of coins may overlap on the first belt conveyor, which is particularly noticeable when a large amount of accumulated coins are dropped or discharged. In such a case, clogging may occur at a place where the direction is changed from the first belt conveyor to the upper direction and the belt is sandwiched between the opposing belts, or the coin is not fully retained and some coins are left behind. Problems such as being caused. In addition, since such dubbables occur accidentally and it is extremely difficult to investigate all the places where abnormalities occur and the abnormal states in advance, it has been impossible to take effective countermeasures.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a coin processing device that can reliably perform a return process by a return mechanism and can be applied to various automation devices. To aim.

[0010]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention performs authenticity determination and denomination discrimination processing of coins inserted from the coin insertion part, and it is possible to detect input items and change due to the occurrence of abnormal situations such as false coin determination. Targeting a coin processing device that performs items to be returned through a return section (return tray) provided in the vicinity of the coin input section, and should be returned by being horizontally arranged below the return section. A first conveyor belt formed by continuously laying a horizontal conveyor part for horizontally conveying an object and an upper conveyor part for changing the conveying direction from the middle to the above-mentioned returning part, and above the first conveyor belt. A belt conveyor mechanism having a second conveyor belt that is laid along the conveyor portion and that cooperates with the first conveyor belt to sandwich and convey an object to be returned to the return section, and the first conveyor belt. The conveyor belt and the second conveyor belt If at least one of the two conveyance speeds is sequentially detected and the conveyance speed deviates from the predetermined permissible speed range, the conveyance directions of the first conveyance belt and the second conveyance belt are set at a predetermined timing. It is configured to include a control means for performing normal and reverse rotation.

[0011]

[Action]

 The first conveyor belt is composed of a horizontal conveyor portion arranged at a lower position of the coin processing device and an upper conveyor portion which is continuous with the horizontal conveyor portion and extends toward the upper return portion. Further, the second conveyor belt is an upper conveyor portion. Since, in normal operation, the object to be returned is placed and transferred on the transfer surface of the horizontal transfer section, the object to be returned is then pinched and transferred upward between the upper transfer section and the second transfer belt. Therefore, it is possible to arrange the coin input unit and the return unit at positions that are easy for the user to handle.

Further, when a conveyance abnormality occurs due to a delay in the belt conveyor mechanism, the detection unit detects it and further determines the conveyance direction of the first conveyor belt and the second conveyor belt to a predetermined direction. Since the normal rotation is reversed at the timing, the stagnant state can be automatically alleviated and resolved, enabling automatic restoration without the need for maintenance personnel.

Further, a change storing mechanism H is provided for storing a large number of coins for change in advance and dropping the coins to the belt conveyor mechanism V when returning the change. Incidentally, the mechanisms disclosed in Japanese Patent Application No. 5-238570 can be applied to the above-mentioned mechanisms A to E.

Next, the structure of the return mechanism G, which is the main technique of the present invention, will be described with reference to FIGS. 3 to 8. First, the structure will be described based on a vertical cross-sectional view (FIG. 3) showing a main structure of the belt conveyor mechanism V provided in the return mechanism G. The belt conveyor mechanism V includes a first conveyor belt 1, a second conveyor belt 2, and a plurality of pulley groups that drive and support the conveyor belt 2. The first conveyor belt 1 is mounted between a drive pulley 3 that rotates by being connected to a drive shaft of a drive motor (not shown) and a plurality of driven pulleys 4 to 11, and is driven by pressing a tension roller 12. The driving force of the pulley 3 is biased. Further, the drive pulley 3 is provided in a relatively close position above the return tray P provided near the coin slot A (see FIG. 1), and the driven pulleys 4, 5, 6, 9, 10 are substantially provided. The driven pulleys 6,7,8,9,10 are arranged in a substantially horizontal direction while being arranged in the vertical direction, and the driven pulleys 6,9,10 among them are arranged in the vertical and horizontal direction changing portions. Therefore, the first conveyor belt 1 realizes an L-shaped conveyor path in the horizontal direction and the vertical direction. The portion extending in a first horizontal direction of the conveyor belt 1 is arranged below the rear side of the through cylinder E ₁ to E ₄ of the coin reservoir mechanism E shown in FIG. 2 (a). Therefore, at the time of the above-mentioned return processing, all the coins or the like to be returned are dropped on the horizontal transfer surface of the first transfer belt 1. Further, although not shown, the change from the change storing mechanism H, which stores change in advance, is also dropped on the horizontal transfer surface of the first transfer belt 1.

On the other hand, the second conveyor belt 2 is interposed between the driven pulleys 13 and 14 arranged near the upper portion of the drive pulley 3 and the driven pulleys 9, 10 and 11 arranged vertically. The tension roller 15 is pressed to prevent loosening. Therefore, the first conveyor belt 1 and the second conveyor belt 2 are in pressure contact with each other at the vertical conveyor path portions supported by the drive pulley 3 and the driven pulleys 4, 9, 10, 11 and both are normally operated. Move at a constant speed.

Further, drop control plates 16 and 16 ′ for preventing returned objects such as change coins and return coins from dropping are provided at both ends of the first conveyor belt 1 and the second conveyor belt 2. It is located opposite. For convenience of explanation, FIG. 3 shows the one side drop restricting plate 16, but in actuality, the other drop restricting plate 16 'is arranged in front of the paper surface so as to face it.

FIG. 4 is a cross-sectional view of essential parts showing a supporting structure of the driven pulleys 4, 5, 6, 7, and 8 on the fall restricting plates 16 and 16 ′ centering on the support shaft 17. The pulley has the same support structure. Therefore, to explain with reference to FIG. 4, the driven pulley 4 (5, 6, 7, 8) is attached to the support shaft 17 bridged between the fall restricting plates 16 and 16 'through the bearings 18 and 18'. The driven pulleys 4 (5, 6, 7, 8) are rotatably provided so as to support the first conveyor belt 1 on the peripheral surfaces thereof. That is, the driven pulleys 4 (5, 6, 7, 8) are freely rotatable on the support shaft 17 fixed to the fall restricting plates 16, 16 '.

FIG. 5A is a cross-sectional view of an essential part showing a structure for supporting the driven pulleys 9, 10, 11, 13, 14 on the fall restricting plates 16, 16 '. It has a holding structure. Therefore, to explain with reference to FIG. 5A, the support shaft 20 is rotatably supported between the pair of bearings 19 and 19 ′ fixed to the positions where the fall restricting plates 16 and 16 ′ face each other. The driven pulleys 9 (10, 11, 13, 14) are integrally fixed to the support shaft 20, so that the peripheral surface of each driven pulley 9 (10, 11, 13, 14) supports the second conveyor belt 2. Has become. That is, the support shaft 20 and the driven pulley 9 (10, 11, 13, 14) are integrally rotated.

Only the driven pulley 10 is further provided with a sensor mechanism for detecting the rotation speed. That is, the rectangular blade 22 is fixed to the tip of the extending portion 21 that extends in the longitudinal direction of the support shaft 20 to which the driven pulley 10 is integrally fixed, and the tip of the blade 22 in the longitudinal direction is fixed. An optical sensor 25 having a light-emitting element 23 and a light-receiving element 24 which are spaced apart from each other and face each other is fixed to a fall restricting plate 16 'or the like. Therefore, as shown in FIG. 5 (b), the blades 22 rotate integrally with the driven pulley 10 and its supporting shaft 20, and the driven pulley 10 and its supporting shaft 20 move at the moving speed of the second conveyor belt 2. Since the optical sensor 25 rotates at a proportional rotational speed, the optical sensor 25 sequentially detects the cycle in which the optical path between the light emitting element 23 and the light receiving element 24 is blocked at the tip portion of the blade 22, and thus the second conveyor belt 2 The moving speed of the can be detected. The detection signal S is input to the frequency detection unit 30 (see FIG. 8A), which will be described later, so that the fluctuation of the moving speed of the second conveyor belt 2 is determined.

Further, as shown in FIGS. 1 and 6, in the horizontal portion of the first conveyor belt 1 and before the position where the second conveyor belt 2 starts the pressure contact, and returned coins or the like are dropped. A rod-shaped or plate-shaped swing rod 26 and a retaining member 28 having a U-shaped curved inner surface directed toward the swing rod 26 are provided at a predetermined position behind the place where the swing rod 26 is moved. The oscillating rod 26 is separated and opposed to the approximate center of the upper conveying surface of the first conveyor belt 1, and one side is rotatably supported and the upper end is supported by the spring 27. It is a pendulum-shaped member that receives the braking force of the spring 27 and tries to stand still. The gap between the lower end and the transport surface of the first transport belt 1 is set to, for example, about 50% of the maximum radius of the treated coins with the maximum radius as the reference. There is. Therefore, when a plurality of coins are conveyed in an overlapping state, the swinging rod 26 abuts the coins, or the coins are conveyed while rolling without rolling completely. The contact coins can be rolled over to achieve the functions of staticizing and flattening the processed coins. The elastic force of the spring 27 and the weight of the swing rod 26 are appropriately set so that these functions are effectively exhibited.

On the other hand, the detention member 28 is entirely made of rubber or synthetic resin having a high friction coefficient, or the U-shaped curved inner side surface is made of at least the same rubber or synthetic resin as described above. Yes, both ends of the curved inner side surface are connected to the inner walls of the fall restricting plates 16 and 16 ', and continuous connecting plates 29 and 29 for preventing a step toward the swing rod 26 from being formed at the connecting parts. 'Is fixed. It should be noted that the both ends of the retaining member 28 may be formed in a tapered shape so that the wall thickness thereof gradually decreases, so that the above-mentioned step is not generated. Further, the gap between the lower end of the detention member 28 and the transport surface of the first transport belt 1 is, for example, a dimension that is about 3% to 5% larger than the maximum radius of the treated coins, based on the maximum radius. Is set to.

As a result of providing the detaining member 28 having such a structure, as shown in FIG. 7A, for example, the rocking rod 26 is rubbed and the fall restricting plate 16 (16 ′) is held. Even if the coin X in a leaning state is conveyed, as shown in FIG. 7B, the moving direction is directed along the curved inner side surface, and the moving energy is consumed due to the high coefficient of friction. Therefore, the coin M rolls over and stands still, as shown in FIG. 7 (c). Also, the coins that have rolled will also be overturned / stationary in the same way. Also, since the gap between the lower end of the retaining member 28 and the transport surface of the first transport belt 1 is set to the above-mentioned dimension, the coin group that has not been sufficiently collapsed by the swing rod 26 is collapsed again and flattened. Be converted.

As described above, the coin flattened and made stationary by the swing rod 26 and the retaining member 28 is sandwiched between the first and second conveyor belts 1 and 2 shown in FIG. As a result of being conveyed, and finally the pinched state above the drive pulley 3 is released, it is dropped / discharged on the return tray P.

By appropriately setting the diameter of the driven pulley 9 in FIG. 3, even when a plurality of coins are still stacked between the first and second transport belts 1 and 2. It can be rolled in smoothly.

Next, a control circuit connected to the optical sensor 25 of the sensor mechanism will be described with reference to FIG. First, to describe the configuration based on FIG. 8A, the detection signal S output from the optical sensor 25 is input to the frequency detection unit 30, and the frequency detection unit 30 detects the frequency from the cycle τ of the detection signal S. . For example, since the detection signal S is a rectangular wave that repeatedly turns on and off in proportion to the rotation speed of the blade 22, the frequency f = 1 / τ is obtained by measuring the period τ with an internal counter or the like.

Detected frequency signal S_fIs transferred to the abnormality determination unit 31, and the abnormality determination unit 31 uses the preset reference frequency f₀And frequency signal S_fThe error frequency Δf with the frequency f is sequentially calculated, and the error frequency Δf is set to a preset allowable range −f._L<Δf <f _H When deviating from, it is determined that the first and second conveyor belts 1 and 2 are not moving at the normal speed.

Particularly, when the frequency f falls below the allowable range (Δf ≦ −f _L ), at least one of the first and second conveyor belts 1 and 2 is clogged with return coins or the like. Is determined to be in an overload state, and based on the result of the determination, a command signal Sc for periodically switching the polarity of the electric power supplied to the drive motor M for driving the drive pulley 3 is output to the motor drive unit 32. Output to. That is, as shown in FIG. 8B, during normal times when the transport speeds of the first and second transport belts 1 and 2 are within the permissible range, the signals Va and Vb output from the motor drive unit 32 are output. Since the polarity and amplitude of the first and second conveyor belts 1 and 2 are constant, the direction of current supplied to the drive motor M through the transistor circuit group is constant, and the conveyor directions and speeds of the first and second conveyor belts 1 and 2 are constant. Becomes On the other hand, when an abnormality is determined (in the case of abnormality in the figure), the polarities of the signals Va and Vb are periodically inverted, so that the current supplied to the drive motor M via the transistor circuit group is increased. The directions are alternately reversed, and the forward / reverse operation of the drive motor M1 associated with this reverses the transfer directions of the first and second conveyor belts 1 and 2 alternately. The control at the time of this abnormality is set to a predetermined period.

In this way, when the first and second conveyor belts 1 and 2 are reversed when an abnormality occurs, for example, the clogging state of returned coins is alleviated, and the conveyor can be automatically conveyed in the normal state. Restore the condition. Therefore, according to this embodiment, it is possible to greatly reduce complicated maintenance management, and at the time of occurrence of an abnormality, even if it causes a slight delay in the return processing, the processing is performed as if the abnormality did not substantially occur. As a result, it is possible to minimize deterioration of service to customers, and to speed up processing and improve reliability in view of comprehensive coin processing.

Normally, after the object to be returned is placed and conveyed on the conveyor surface of the horizontal conveyor section, The sheet is sandwiched and conveyed upward between the conveying portion and the second conveyor belt. Therefore, it is possible to arrange the coin insertion part and the return part at positions that are easy for the user to handle. Further, when a conveyance abnormality occurs due to a stagnation in the belt conveyor mechanism, the detection means detects the abnormality and further reverses the conveyance direction of the first conveyor belt and the second conveyor belt at a predetermined timing.
