BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a lift drive mechanism used for transporting coins in a money handling machine used in a financial institution or the like, in particular, a coin handling machine.
[0002]
[Prior art]
Conventionally, in a lift drive mechanism that moves a lift member that can move up and down freely by moving a drive belt stretched around a plurality of pulleys, a lift member (coin) is disclosed in Japanese Patent Laid-Open No. 8-305917. The elevating mechanism 42 for elevating and lowering the supply unit 41) has a lock mechanism 82 for restricting elevating movement of the elevating body 72 at the upper position, and this lock mechanism 82 is formed along the vertical direction. The lock plate 85 is engaged with or released from the hook 83 attached to the lift plate 73 and the lock hole 84 formed in the lock plate 85 by driving a solenoid 87 that moves the lock plate 85. A mechanism that regulates the downward movement of the supply part 41) is disclosed.
[0003]
[Problems to be solved by the invention]
However, in such a mechanism, since the lift member moves up and down at the same speed as the moving speed of the belt to be stretched, the higher the moving speed, the more the timing for stopping the motor drive is slightly shifted. , When the lift member stops, it is highly likely that the height position will deviate significantly from the target position, and the movement of the lift member stops completely at the same timing as when the drive of the motor is stopped Therefore, it is very difficult to stop the lift member accurately and stably at a predetermined height position, causing problems that the workability of the coin transfer work is poor, and coins that are heavy in weight, etc. , Even if the lift member can be accurately stopped at the target position, once the motor is stopped, coins, etc. Since the lifting member is likely to drop by weight, is provided with the locking mechanism, the weight up and cost is the number of parts, also caused a problem that.
[0004]
Accordingly, an object of the present invention is to accurately move the lift member that can move up and down, which stores coins, to the target upper position, and even after the movement, the lift member may move from the target upper position due to the weight of the coin or the like. It is an object of the present invention to provide a lift drive mechanism that can be stably stopped so as not to have a good workability in the operation of transporting coins and that can achieve a cost reduction with a simple mechanism.
[0005]
[Means for Solving the Problems]
The lift drive mechanism according to the present invention is a lift drive mechanism that moves a lift member that can move up and down, which stores coins, by driving a drive belt stretched around a plurality of pulleys. At least two positions of the drive belt Further, both connecting pins provided at a distance in the rotational direction of the drive belt, a plate connecting the connecting pins, and the lift member is lifted when moving up and down by being located at a substantially central position of the connecting pins of the plate. A liftable lifting member provided at a possible position, wherein the two connecting pins cross the upright boundary passing through the center of rotation of the upper pulley over which the drive belt is stretched. It is configured by setting the upper position above the ascending.
[0006]
According to the above configuration, when the motor that drives the drive belt is stopped so that the two connecting pins straddle the upright boundary line passing through the rotation center of the upper pulley, the lifting member may be made of a coin or the like. Even if it is heavy, the lift member can be accurately stabilized and stopped at the desired upper position without lowering, the workability of the coin transfer work is good, and the cost is reduced by a simple mechanism it can.

Alternatively, a position detection sensor 34 (only a sensor corresponding to the upper position is shown) that detects the detection body 33 when the lower position is reached is provided.
[0021]
Hereinafter, processing of the entire coin processing machine will be described.
[0022]
As the depositing process, first, when the coins are inserted from the opened depositing slot 11 by the movement of the slide shutter 12, the rotating disk 13 rotates to feed out the coins one by one and The true / false / injury / denomination is selected by a deposit discrimination unit (not shown), and only genuine coins are classified into denominations, temporarily stored in the deposit temporary storage unit B, and the deposit process is performed by an operation unit (not shown). If canceled, the bottom plate 15 moves to release the temporarily stored coins to the return box 16, and when the deposit confirmation operation is performed by an operation unit (not shown), the temporary storage box 14 and the bottom plate 15 are temporarily moved. 1 and moves to the position indicated by the alternate long and short dash line in FIG. 1 and only the bottom plate 15 returns from that position to the position indicated by the solid line, whereby the coin placed on the bottom plate 15 Housed in the storage box 19 of the individual storage unit C via the over preparative 17, the depositing process is completed.
[0023]
As a withdrawal process, when a withdrawal command is received from a host machine (not shown), first, the rotary disk 23 of the individual operation unit D rotates according to the type of coin to be dispensed, and the withdrawal transport unit E Coins corresponding to the number of withdrawals are discharged onto the conveyor belt 24.
[0024]
Note that if there are not enough coins on the rotating disk 23 based on the detection result of a sensor (not shown), the coins stored in the storage 19 corresponding to the denomination are supplied to the rotating disk 23 by the supply belt 22. The withdrawal coins transported by the withdrawal transport unit E are discriminated by the withdrawal discrimination unit (not shown), and the identified coins are temporarily stored in the withdrawal temporary storage unit F.
[0025]
In this way, if all the coins to be withdrawn are stored in the temporary storage unit F and the result of discrimination in the withdrawal discrimination unit (not shown) matches the withdrawal amount specified in advance, the bottom plate 26 is slid. The withdrawal coins are then released, the temporarily stored coins are released to the lift member 1 through the chute 27, and all the withdrawal coins released from the withdrawal temporary storage unit F are stored in the lift member 1. When a sufficient time elapses, the motor 31 is driven, and the lift member 1 rises through the pulleys 2 and 3, the drive belt 4, the plate 7, and the lifting member 8.
[0026]
Here, when the drive of the motor 31 is confirmed from the detection result of the detection body 33 by the position detection sensor 34 that the plate 7 and the lifting member 8 have reached the position shown in FIG. 4, it is determined that the upper position has been reached. Then, the drive of the motor 31 is stopped.
[0027]
This is because if the drive belt 4 is overrun by the same distance, the intermediate position on the outer periphery of the pulley 2 is defined as the upper position, compared to the case where the connecting pin 5 is configured as an upper position in the middle of the vertical portion of the drive belt 4. This is because the fluctuation of the height difference is much lower in this case, that is, the connecting pin 5 provided on the drive belt 4 moves along the outer periphery of the pulley 2 as shown by the track X of the connecting pins 5 and 6. This is because the ascending / descending speed of the connecting pins 5 and 6 during the operation becomes slower than the ascending / descending speed of the drive belt 4 at the vertical portion, and the closer to the upper position of the outer periphery of the pulley 2 the closer the ascending / descending speed is. It becomes more gradual.
[0028]
Furthermore, since the track Y of the lifting member 8 provided on the plate 7 supported by the connecting pins 5 and 6 is more gentle than the track X of the connecting pins 5 and 6, the connecting pins 5 and 6 Even if the drive belt 4 may overrun slightly when stopped at the upper position along the outer periphery of the pulley 2, the lifting between the connecting pins 5 and 6 on the outer periphery of the pulley 2 is possible. The variation in the height position of the member 8 is very small. Further, as shown in FIGS. 4 and 5 as the upper position, the connecting pin 5 and the connecting pin 6 cross the boundary line O with the upright boundary line O passing through the rotation center of the pulley 2 as a boundary. By stopping so as to be in a relationship, even if the lifting member 1 and the weight of the coin are applied to the lifting member 8, the drive belt 4 does not move in any direction, so that the lifting member 1 is lowered. Thus, there is no need to provide a lock mechanism, and when the lift member 1 is moved to the upper position in this manner, a shutter (not shown) of the dispensing port 18 is opened, and dispensing coins can be taken out.
[0029]
In the embodiment of the present invention, the timing for stopping the driving of the motor 31 at the upper position is the state shown in FIG. 4 in consideration of overrun. However, as described above, the boundary line If the connecting pin 5 and the connecting pin 6 are stopped so as to have a positional relationship across the boundary line O with O as a boundary, the above-described lowering of the lift member 1 can be prevented.
[0030]
Further, the place where the detection body 33 and the position detection sensor 34 are provided for viewing the timing of stopping the rotation of the motor 31 at the upper position shown in FIG. A configuration may be adopted in which the driving of the motor 31 is stopped by detecting the height position of the lift member 1 lifted by the member 8, and the position where the lifting member 8 is provided is as shown in FIG. In addition, when the connecting pins 5 and 6 are provided at an intermediate position (on the boundary line O) when the connecting pins 5 and 6 are located on the horizontal line, the descent of the lift member 1 can be regulated most stably.
[0031]
【The invention's effect】
As described above, according to the present invention, the lift member that can move up and down for storing coins can be accurately moved to the target upper position and moved from the target upper position by the weight of the coins after the movement. Therefore, it is possible to provide a lift drive mechanism that can be stably stopped so as not to occur, the workability of the coin transfer operation is good, and the cost can be reduced with a simple mechanism.
