Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a coin discharging device incorporated in an automatic ticket vending machine or other automatic vending machines.

[Prior art]

Conventionally, a coin ejection device ejects a coin in a hopper by rotating a coin ejection disc (hereinafter referred to as a disc) provided at a lower portion of a change hopper by a motor driven based on a return signal or a recovery signal. I am trying to do it.

[Problems to be solved by the device]

However, in the conventional coin ejector, the rotational speed of the disc based on the return signal and the rotational speed of the disc based on the recovery signal are set to be the same (for example, 60 rpm). There was a problem that the stop time of the automatic ticket vending machine etc. built in was unduly long. In order to solve such a problem, it is sufficient to increase the rotation speed of the disc. However, if the rotation speed is simply increased, a serious problem of over-discharging will occur, which will be described in detail in Examples below. Certainly, JP-A-63-131296 or JP-A-63-1461
As shown in Japanese Patent Publication No. 94, in order to improve the processing capacity of an ATM (automatic deposit / withdrawal device), it is also proposed to change the speed of the internal transfer mechanism depending on the frequency of use of the ATM or the number of customers lined up in front of the ATM. ing. However, this variable is also carried out within the range where the paper money is not jammed. Therefore, when this technical idea is applied to the conventional coin discharging device, the upper limit of the rotation speed is based on the return mode and cannot be applied as it is. Therefore, in order to solve the above problems, the present invention has been made as a result of earnest research on the coin discharging operation in the return mode and the collecting mode, and its purpose is to provide a coin discharging device having high processing efficiency. is there.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the device of the present invention rotates a coin discharging disc provided at the bottom of a hopper for storing coins by a motor driven based on a return signal or a recovery signal, and then the hopper. The coin discharging device adapted to discharge the coins therein is characterized by comprising motor driving means for making the rotation speed of the motor faster when outputting the recovery signal than when outputting the return signal.

[Action]

In the above structure, the motor driving means rotates the disk at the time of outputting the recovery signal at a higher rotation speed of the motor than at the time of outputting the return signal.

【Example】

Before explaining the embodiments, in order to facilitate understanding of the device of the present invention, the coin discharging operation in the returning mode and the collecting mode will be described. In the return mode, the rotation angle of the disc must be strictly controlled. This is because, for example, if the disk has five holes for taking in coins, in order to eject one coin, one rotation of 360 ° from the start of rotation will start. Angle (72 °)
Have to stop at. Therefore, the disc is set to a rotation speed having an initial speed that can be reliably stopped at such a rotation angle. In other words, if the rotation speed of the disc is too high, the disc will overrun due to the inertia of the disc, and the next hole in which the coin is inserted will also be located in the discharge passage, and the coin in that hole will also be discharged, resulting in excessive discharge. Will occur. On the other hand, in the collection mode, not only one coin is collected, but all coins are collected from the hopper, or the excess coins are collected when more than necessary change is stored in the hopper. Since it is time to collect, it is not necessary to stop the rotation angle of the disc with one coin.
Therefore, in the recovery mode, it is possible to adopt a rotation speed of the disc that allows the coin inserted into the hole of the disc to be reliably ejected from the ejection passage. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partial cross-sectional view of the apparatus of the embodiment, in which 1 is a hopper, 2 is a discharge part, and 3 is a motor. The upper part of the hopper 1 is open so that coins inserted into an automatic ticket vending machine body (not shown) can be sorted by denomination or coins falling from a supply cassette can be received. The discharging unit 2 has the same mechanism as the discharging mechanism of a known coin discharging device, and is provided in the lower portion of the hopper 1. That is, the disc 4 rotated by the motor 3 is provided at the bottom of the discharge portion. As shown in FIG. 2, a plurality of holes (5, 5 in this embodiment) having a diameter slightly larger than the coin diameter of the denomination stored in the hopper 1 are opened in the disc 4. Has been done.
Therefore, the coin inserted into the hole 5 is configured to be discharged outward when the disc 4 rotates and is located in the discharge passage 6. Although not shown, the discharge passage 6 is provided with a stopper pin for receiving the coin in the hole 5 and a movable roller for ejecting the received coin outward, as in a known discharge unit. The motor 3 is composed of a pulse motor (stepping motor), and is fixed to the pedestal 7 of the hopper 1 and its rotating shaft 8 is fixed to the disc 4. A damper 9 movable by a solenoid (not shown) driven in the return mode and the recovery mode is provided outside the discharge passage 6, and the discharge direction of the passage 10 is changed depending on the state of the damper. That is, when the damper 9 is positioned in the upright position as shown by the solid line position,
The coins discharged from the discharge passage 6 are transferred to the recovery box (not shown) in the direction of arrow A, and when the damper 9 is located in the lower position as indicated by the chain double-dashed line, the coins are discharged from the discharge passage 6. The coins coming are transferred in the direction of arrow B in the direction leading to the return port (not shown). FIG. 3 is a block diagram of the drive circuit of the motor 3,
A pulse generation circuit 11 and a frequency conversion circuit 12 for converting the frequency of the pulse signal output from the pulse generation circuit 11.
And the pulse signal from this frequency conversion circuit 12 to the motor 3
Is composed of a pulse distribution circuit 13 for rotatably distributing and a pulse power circuit 14 for amplifying the pulse signal distributed by the pulse distribution circuit 13. The frequency conversion circuit 12 is configured such that a return signal is input from a controller of the automatic ticket vending machine body (not shown) in the return mode so that the rotation speed of the motor 3 becomes a predetermined rotation speed, for example, 60 rpm. The frequency of the pulse signal is set to. Further, in the recovery mode, a recovery signal is input from the controller, and the rotation speed of the motor 3 is set to a rotation speed higher than that in the return mode, for example, 120 rpm. Therefore, in the return mode, the disc 4 is rotated at a safe rotation speed without excessive discharge, and in the recovery mode, the disc 4 is rotated at a higher rotation speed than in the return mode. Therefore, in the collecting mode, the coins in the hopper 1 are quickly discharged, so that the time required for collecting can be shortened and the operating time of the automatic ticket vending machine main body can be increased accordingly. In the above-mentioned embodiment, the main body in which the coin discharging device is incorporated is the automatic ticket vending machine, but it may be another automatic vending machine or an ATM capable of processing coins. Although the motor 3 is a pulse motor, any motor capable of rotation control such as a servo motor may be used.

[Effect of device]

In the device of the present invention, the disk rotated by the motor is rotated in the collecting mode faster than in the returning mode, so that the collecting time can be shortened, and the operating time of the automatic ticket vending machine etc. can be increased by the shortened time. You can
