Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a temporary coin holding device in a vending machine or the like.

In a vending machine such as an automatic ticket vending machine that sells many types of tickets and goods, a customer operating the vending machine may misunderstand the deposit, etc., and may be asked to inquire about the deposit. Therefore, a hold function is required to temporarily hold the deposit of the current customer until the next customer operates the vending machine.

By the way, conventional vending machines are configured to store coins by stacking them in a coin inspection and coin sorting pipe, etc., mainly by sorting the coins by appearance.

However, in such a conventional temporary holding system, it is necessary to prevent coins from being mixed together by always holding only the coins inserted by one customer in the coin holding part such as a pipe. Therefore, when the operator starts operating, the held coins must be moved to the coin collection section or the coin discharging section, which takes time to count and sell the coins that are initially inserted. There were drawbacks. In addition, there is a transparent coin that temporarily holds the coins (if a large number of coins are stacked on the eve, it is difficult to ascertain the number of coins held. Furthermore, the number of coins that can be inserted in one transaction is If the number of coins per coin is, for example, 15, and four types of coins are allowed, the storage capacity for 60 coins is required, which has the disadvantage of requiring a large amount of space for storage.

The purpose of the present invention is to eliminate such conventional drawbacks, and by holding and moving the inserted coins in a continuous manner in a row, the sales processing speed of goods can be increased. To provide a temporary holding device for coins in which it is easy to confirm the number of held coins and the storage space can be reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the drawings. Fig. 1 is a front view of a temporary coin holding device according to an embodiment of the present invention, and Fig. 2 is a plan view thereof. In these figures, continuous insertion of coins into the inside of the coin slot 1 is prohibited. A continuous insertion prevention stopper 2 and a detection switch SWI that closes when coins pass are provided. 3+ is a solenoid that drives the continuous injection prevention stopper 2. A coin verification unit 4 is provided along the path through which coins pass, and the type of coin,
Authenticity, etc. is determined electronically. At the exit of the coin verification section 4, there is a refund button 5 that returns the coins when a fake coin is used.
s and a detection switch SW2 are provided. 6 is a solenoid that drives the refund flapper 5. Furthermore, a coin drop tube 1 is provided along the path through which coins pass. The coin drop tube 7 is a cylindrical body for surely dropping coins to a predetermined position on the belt 9) of the conveyor 8, and as shown in FIG. The lower end of the left semicircle is configured so that there is a gap of one #1 coin between the two and the bottom end of the left semicircle, and the space between the two and the #1 coin is two coins apart.

The conveyor 8 holds and conveys coins, and is driven by a motor M via a drive bait 10. The motor M simultaneously drives the presser plate 12a via the pulley 11 and the presser plate μ)'12b via the pulley 13. The presser plate 9112m holds and conveys coins together with the plate IL/) 9, and guides the coins to the coin sorting section 14. The coin sorting section 14 is for dropping coins into a hardening machine (not shown), and the details thereof are shown in FIG. 3. FIG. As shown in this figure, the coin sorting section 14 has a groove 14a in the center, and 1!
It is a rectangular plate-like body with an opening 14b provided therein, and is rearranged so as to be parallel to the presser belt 12a. The opening 14b is made up of four types of openings that are configured to become larger sequentially in accordance with the size of, for example, class 4 coins, and coins of a predetermined type fall into the separation tubes 15a-15d from the predetermined openings. *The left side of the Thj 14a is constructed so that the coin ends are aligned in a constant manner, so that it gradually becomes unskillful. FIG. 3(b) is a W-W @ cross-sectional view.

This figure shows the relationship between the groove 14sr of the coin sorting section 14, the opening 14b% presser belt 12a, and the separation tube 15c, and only coins of the size shown by the dashed line are given to the separation tube 15.

On the other hand, behind the coin dropping tube 7, a return stopper 17 driven by a solenoid 6 is arranged as shown in FIG. The return stopper 17 prevents deposits from falling into the return slot 18 due to malfunction or vibration, and the solenoid 16
A return path is provided to return the coins when the machine is driven. A detection switch SW is provided in the return path to detect the return of coins.

Next, a block diagram of the electric circuit of the coin holding device of this embodiment will be explained with reference to FIG. The signals from the coin verification section 4 and the detection switches 5W-1, 5W-2, and 5W-3 are converted into digital V signals by an input signal circuit 19, and are applied to a coin processing section control circuit 20 containing a microcomputer. There is also a purchase button 21 operated by the customer.

The signal of the cancel button 22 is the main control circuit 23 of a vending machine, etc.
The signal is applied to the coin processing section control circuit 20 via the control circuit 20.

The coin processing section control circuit 20 controls the operation of the hardwood temporary holding device based on these signals, and its output is sent to the motor M via the output drive circuit 24.

and solenoid 3, 6.16. Time circuit 2
Reference numeral 5 provides various time information to the coin processing unit control circuit 20.

Next, the operation of this temporary coin holding device will be explained with reference to the flowchart shown in FIG. Numbers indicated using leader lines are codes indicating each step.

First, when a customer inserts a coin into the coin slot 1, the detection switch 5W-1 is turned on for a moment as the coin moves, and then turned off immediately. Although the solenoid 3 is normally on and the continuous input prevention horn (2) is inactive, the coin processing unit control circuit 20 detects when a coin has passed through the detection switch 5W-1 by a signal from the detection switch 5W-1. is detected (step 30), and the solenoid 3 is turned off.As a result, the stopper 2 for preventing continuous insertion protrudes into the coin passage, and continuous insertion is prevented (step 31). The coin section 4 inspects the type and authenticity of the coin (step 32 - If the coin is true, the coin is thrown into the bed 9 of the conveyor 8 through the coin drop tube 7 (steps 33 to 36). ), at this time, the passage of the coin causes the detection switch 5W-2 to turn on momentarily and then turn off immediately. It is detected that the detection switch 5W-2dE is turned on and turned off by the signal from the detection switch 5W-2 ( Step 34) and rotate the motor M for a predetermined period of time to move the base 9 in the direction of the arrow (Step 35)
The rotation time of the motor M is defined as the time required to move the belt 9 by the maximum diameter of the coin used, and is assumed to be 02 seconds here. Then, the solenoid 3 is driven again to deactivate the continuous injection prevention stopper 2 (step 36), step 3
3, when it is detected that the inserted coin is a fake coin, the coin processing unit control circuit 20 drives the solenoid 6 to displace the refund flipper 5 to the position shown by the two-dot chain line in FIG. 1 via the link. (Step 46 - In this way, the fake coin leaves the coin verification section 4 and is immediately returned to the return slot 18.Detection switch sw-m detects passage of a coin and temporarily outputs an on signal, controls the coin processing section The circuit 20 detects this (step 4), turns off the solenoid 6, returns the return flapper 5 to its original position (step 48), and further drives the solenoid 3 to disable the continuous injection prevention stopper 2. (Step 36). If a coin is subsequently inserted here, the process returns to step 30 via steps 37 and 38, and the same operation is repeated. As a result, the coins inserted onto the base 9 form a chain as shown in FIG. You will be lined up in

In order to prevent the coins continuously inserted into the coin drop tube 7 from stagnation, the angle of the passage is adjusted so that the time required to reach the detection switch 5W-2 from the coin insertion slot 1 is at least 2 seconds. When the customer presses the purchase button 21 for which the distance has been set, the coin processing unit control circuit 20
detects this in step 38 and switches the motor M to 04
The coin is rotated in the normal direction for a second to create a space on the base 9 of the compare 8 that is approximately the size of two coins (step 39). As shown in FIG. 6, rows of coins are formed intermittently on the belt 9 for each customer. In this way, the coins inserted by the customer are placed on the bear 1/) 9 and on the presser peg v following the belt 9.
) 12a. In the embodiment shown in FIG. 1, from A on the presser foot 9 to the presser foot M! Coins can be held up to position B in a.

Thereafter, the coins are given to the coin sorting section 14, sorted by type, and put into a change dispenser (not shown) from the dispensers 15a to 15d.

On the other hand, if the customer presses the cancel button 22, the coin processing unit control circuit 20 detects this in step 37, and reverses the motor M to convey the inserted coin on the tray 9 in the opposite direction of the arrow in FIG. The coin is started (step 40 - simultaneously turning on the solenoid 16 and step 41), and the return stopper 15 is operated to enable the coin to be returned.

Then, the coins are sequentially given to the return slot 18 from the base 9. While the coins held in this way are returned, if the last coin inserted falls from the zero coin drop tube 7 into the column of coins 9, as described above, the left side of the coin drop tube f Since the lower end of the semicircle is spaced from A/)9 by two coins, it is possible to return two coins at the same time. Here, the detection switch 5W-3 is turned on at the stop where the coin passes over the belt 9 immediately before being returned. Since the coins inserted are consecutive for each customer, the detection switch 5W-WLT will be turned on continuously or turned on and off at intervals shorter than 0.3 seconds depending on the movement of the coins of the customer who requested the cancellation. repeat. When all of this customer's coins are returned, it will take approximately 4 seconds for the row of coins inserted by the previous customer to pass through the detection switch 5W-3. Therefore, when it is detected that the detection switch 5W-a is off for, for example, 03 seconds (step 42), it is determined that the return of the coin to the customer has been completed, and the solenoid 16 is turned off and the return stop button (15 is ff1dAiL4!7(,xy
7' 43) , "!= -I M. Stop the reverse rotation (step 44), and then rotate the motor M forward for α5 seconds to create a sufficient gap between it and the coins inserted by the primary customer. (Step 45) 6 As described above in detail, according to the present invention, the inserted coins are temporarily held by the pusher of the 111st conveyor and conveyed to the coin sorting section 14. Therefore, unlike the conventional holding device, there is no need to feed the coins held in the coins to the change dispenser for each transaction, and the operational time for human injury is shortened.

Furthermore, since the inserted coins are continuously held on the Pesito for each transaction, even if a large number of coins are used, the number of coins held can be confirmed at a glance.

Furthermore, since a conveyor is used to hold the coins, it does not take up much space, and in particular, the height of the holding device can be maintained at a high level.

Incidentally, the coin holding capacity can be easily increased by increasing the presser base as necessary. When the storage capacity is increased in this way, it is possible to increase the capacity not only for the previous customer but also for the previous customer!・
It is also possible to make it possible to answer inquiries about the amount of money invested.
