Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a change dispensing device for dispensing change in a vending machine or the like.

(Prior Art) Conventionally, as this type of change dispensing device, the one shown in FIG. 2 is known (Japanese Patent Application Laid-Open No. 161995/1983).
That is, a fixed plate 3 having a plurality of change dispensing ports 2 is provided on the device board 1, and a slidable change dispensing plate 5 for storing the lowest coin of a plurality of coin chips 4 is provided on the fixed plate 3. ing. A selector 6 is provided on one side of the change dispensing plate 5 for reciprocating the change dispensing plate 5 to the respective change dispensing ports 2. A plurality of slide plates 7 are interposed between the fixed plate 3 and the change dispensing plate 5 so as to face each coin tube 4, and the change dispensing plate 5 and each slide plate 7 are always connected by connecting pins (not shown). When a change dispensing signal is sent out, the connected state of the corresponding connecting pin is released by a solenoid (not shown).

According to this change dispensing device, when the change dispensing signal is sent out, the connection pin on the slide plate 7 side corresponding to the signal is released. Next, the selector 6 is reciprocated by a drive cam 8 connected to a motor (not shown), and the slide plate 7, which is engaged with the change dispensing plate 5 by a connecting pin, reciprocates. As a result, the coins on the slide plate 7 that are in the engaged state move back and forth on the slide plate 7, and on the other hand, the coins on the slide plate 7 that is disengaged are moved by the change dispensing plate 5 that moves back and forth. Change is paid out from the change payout opening 2.

Further, as another conventional example, the one shown in FIG. 3 is known (Japanese Patent Laid-Open No. 57-52632). That is, upper plate 1
A plurality of slide plates 12 are interposed between 0 and a lower plate 11, and a plurality of coin cubes 13 are erected on the upper plate 10. Each slide plate 12 is provided with a plurality of drive cams 16 connected to a motor 15 via a gear mechanism 14 on one side thereof, and is a change dispensing device in which each slide plate 12 is reciprocated by each drive cam 16. .

(Problem to be Solved by the Invention) In the former change dispensing device, when a change dispensing signal is sent out, coins are placed on the slide plates 7 other than the selector 6 and the slide plate 7 corresponding to the signal. The problem is that the load on the motor becomes extremely large. Further, in the latter change dispensing device, only the slide plate 12 corresponding to the change dispensing signal is driven by the drive cam 16, and the load on the motor is reduced. were installed, and the structure was complex.

Also, there is a known change dispensing device that reduces the load on the motor, similar to the latter change dispensing device, as shown in FIGS.
No. 5892.

This change dispensing device includes a disk 31 that rotates via a transmission means 30 connected to a motor (not shown).
The selector 32 has a selector 32 that reciprocates back and forth, and a slide member 34 that accommodates the lowest coin of the coin cube 33, and the selector 32 and slide member 34 are installed on a fixed base plate 35.

According to this change dispensing device, when a change dispensing signal is received, the connecting pin 37 pushed up by the solenoid 36 is passed through each hole 32a, 34a to connect the selector 32 and the slide member 34. The slide member 34 corresponding to the signal is reciprocated to pay out a predetermined coin.

In this way, the slide member 34 corresponding to the dispensing signal slides, and the other slide members 34 do not move, so that the load on the motor can be reduced. Further, a position regulating member 38 protrudes from the upper surface of the fixed substrate 35, and this position regulating member 38 comes into contact with the front end of the slide member 34 in the standby position to fix the slide member 34 in the standby position.

However, according to this change dispensing device, when the selector 32 and the slide member 34 are connected to perform a dispensing operation, the connecting pin 37 moves below the coin tip tube 33, as shown in FIG. 6b. On the other hand, the coins housed in the coin tube 33 often have water droplets and dust attached to them, and this water and dust become sticky muddy water and drip through the lower opening 33a of the coin tube 33. There are times. Therefore, this muddy water adheres to the connecting pin 37 that has moved below the coin tube 33.
This muddy water hardens and interferes with the connection and release operations of the connection pin 37, which is a problem.

In addition, the position regulating member 38 allows the slide member 3 to
Although the standby position of the selector 32 and the slide member 34 is fixed, there is no member for regulating the position of the selector 32 and the slide member 34, so the selector 32 may be damaged due to external vibrations, shocks, etc.
There is a possibility that the opposing positions of the hole 32a of the slide member 34 and the hole 34a of the slide member 34 may be shifted. As a result, when the selector 32 and the slide member 34 are connected by the connecting pin 37, a problem arises in that a connection failure occurs.

Further, the connecting pin 37 connecting the selector 32 and the slide member 34 is constantly subjected to shear stress during the change dispensing operation, and there is a risk that the connecting pin 37 will be damaged after long-term use.

In view of the above-mentioned conventional problems, the purpose of the present invention is to prevent malfunction of the connecting pin due to water etc. adhering to the connecting pin, as well as to prevent malfunction of the connecting pin. An object of the present invention is to provide a change dispensing device that can prevent damage.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention has a plurality of coin cubes for storing coins, and a slide provided with a coin receiving hole to accommodate the lowest coin in each of the coin cubes. A plurality of slide plates that are freely movable, a change dispenser provided in the sliding range of the coin receiving hole of each of the slide plates, a selector that is provided so as to be reciprocated in the sliding direction of each of the slide plates, and change. A connecting pin connects each slide plate and the selector by a solenoid when receiving a change dispensing signal, and a connecting pin that reciprocates the selector via a transmission means when receiving a change dispensing signal, and each slide by reciprocating the selector. A change comprising: a driving means for moving a plate rearward from a standby position and further reciprocating it forward; and a position regulating member abutting the front end of each slide plate at the standby position of each slide plate. In the dispensing device, each slide plate is provided with a protruding connection frame that accommodates each connection pin, the selector is arranged on the upper surface of each connection frame, and each connection pin is connected to each slide plate. The selector can be freely connected through a hole communicating with the selector, and a protruding piece extending downward is provided at the lower end of the selector, and the protruding piece is attached to each connecting frame perpendicular to the sliding direction of each slide plate. It is characterized in that it is provided so as to come into contact with the rear end side surface of each slide plate among the side surfaces.

(Function) According to the present invention, when a change payout signal is sent out, the solenoid that receives the signal is driven, and one or more slide plates are connected to the selector by a predetermined connecting pin. Then, as the selector is reciprocated by the drive means, the coin receiving hole of the connected slide plate is reciprocated to accommodate the lowest coin of the coin tip, and the coin is removed from the change outlet provided in the sliding range. Fall.

In addition, the connecting frame that accommodates the connecting pin protrudes from the slide plate, and is connected to the selector located on the top surface of this connecting frame, so that when the slide plate is dispensing the coin, the connecting pin moves downward from the coin tip. Since it does not move, muddy water etc. attached to the coin will not attach to the connecting pin.

Furthermore, since the protruding piece extending from the lower end of the selector is in contact with the rear end side of each slide plate among the side surfaces of the connecting frame, this protruding piece presses the connecting frame of the slide plate during the return trip of the slide plate. Therefore, the shear stress on the connecting pin is reduced during this return trip.

Furthermore, when the slide plate returns to the standby position,
The front end of the slide plate is controlled by the position regulating member, and
Since the positions of the rear ends of the slide plates are regulated by the protruding pieces of the selector, the selector and the slide plate are fixed at predetermined positions, and the holes through which the connecting pins are inserted can be appropriately opposed to each other.

An engagement hole 222 to be engaged with is provided respectively.
Further, a protruding piece 2 is provided at one end of the lower surface of the selector 22.
23 is provided, and the surface of the connecting frame 212 perpendicular to the sliding direction of each slide plate 21 is in contact with one side surface 212a on the rear end side of the slide plate 21. As shown in FIG. 4, each rotating cam 2 is provided in the guide groove 221.
A cam pin 261 protruding from the periphery of 6 is inserted. Further, each rotating cam 26 is connected to a motor 28 via a gear mechanism 27 to reciprocate the selector 22 in the width direction of the apparatus stand 20.

The solenoid 24 has an arm 242 having a U-shaped cross section attached to the lower end of a plunger 241 extending downward, and a coil spring 243 is interposed between the arm 242 and the solenoid 24 to bias the arm 242 downward. ing. Further, the connecting frame 212 of the slide plate 21 and the selector 22 are interposed between the upper plate and the lower plate of the arm 242, and the head of the connecting pin 23 is provided on the upper surface of the lower plate of the arm 242. 231 is installed.

In addition, 29 is a connecting frame 212 of the slide plate 21.
The guide plate is inserted into the inside of the connecting frame 212.

According to this embodiment, when the change dispensing device is in a standby state, the solenoid 24 is not energized and the arm 242 is positioned downward due to the biasing force of the coil spring 243, as shown in FIG. 5a. Further, the connecting pin 23 is also accommodated in the connecting frame 212 of the slide plate 21 by the biasing force of the coil spring 233, and the slide plate 21 and the selector 23
is in an unconnected state.

And from the control device (not shown) of the vending machine.
When a change payout signal for a 100 yen coin is sent,
As shown in FIG. 5b, the solenoid 24 corresponding to the slide plate 21 for dispensing the 100 yen coin is energized, and the arm 242 is pulled up against the biasing force of the coil spring 243. As a result, the connecting pin 23 also moves upward against the biasing force of the coil spring 233, and passes through the pin insertion hole 214 to the base 2.

Further, as described above, when the change payout signal is sent out, the motor 28 is energized a little later than the solenoid 24 is energized. This results in
The rotary cam 26 rotates via the gear mechanism 27, and the cam pin 261 reciprocates along the guide groove 221, so that the selector 22 moves as shown in FIG.
It reciprocates in the width direction of the device stand 20 as shown in FIG.
As the selector 22 moves, the connecting pin 23
The slide plate 21 connected to the selector 22 also moves in the same manner as the selector 22 while accommodating the lowest 100 yen coin in the coin cube 25. During this movement, the coin receiving hole 213 of the slide plate 21 passes over the change dispensing port 201 of the device stand 20, and a 100 yen coin is dispensed through the change dispensing port 201.

By repeating this procedure for the slide plate 21 of the 50 yen coin, change will be dispensed.

In this way, when dispensing change, the selector 22 and the slide plate 21 corresponding to the change dispensing signal are used.
Since the motor 28 is only driven by the motor 28, there is no need to apply an overload to the motor 28 as in the conventional case. Further, since the rotary cam 26 is not provided for each slide plate 21 as in the conventional case, the structure is simplified.

In the embodiment described above, the timing of energization of the solenoid 24 and the motor 28 is staggered to allow the sliding plate 21 to operate smoothly. When the cam pins 261 of 26 are given play, the reciprocating movement of the selector 22 is somewhat delayed from the connecting movement of the connecting pin 23, and even if the solenoid 24 and the motor 28 are energized at the same time, they operate smoothly.

Furthermore, a protruding piece 2 formed on the selector 22
23 is a surface of the connecting frame 212 that is perpendicular to the sliding direction of each slide plate 21 and is in contact with one side surface 212a on the rear end side of the slide plate 21, so that the protrusion does not occur during the return trip of the slide plate 21. The piece 223 presses the connecting frame 212, and the slide plate 21 and selector 22 can reduce the shear stress applied to the connecting pin 23, thereby preventing the connecting pin 23 from being damaged.

Furthermore, when the slide plate 21 returns to the standby position, the front end of the slide plate 21 touches the position regulating member 202.
In addition, the position of the rear end of the slide plate 21 is regulated by the protruding piece 212a of the selector 22. Thereby, the selector 22 and the slide plate 21 are fixed in a predetermined position, and the holes 214 and 222 through which the connecting pin 23 is inserted can be appropriately opposed to each other. Therefore, the connecting operation of the connecting pin 23 can be performed reliably.

Furthermore, a connecting frame 21 that accommodates the connecting pin 23
2 protrudes from the slide plate 21 and connects with the selector 22 located on the top surface of this connection frame 212, so that this connection pin 23 moves below the coin tip tube 25 during the payout operation of the slide plate 21. Therefore, muddy water etc. attached to the coin will not attach to the connecting pin.

(Effects of the invention) As explained above, according to the invention, the connecting frame that accommodates the connecting pins is provided protruding from the slide plate, and is connected to the selector located on the top surface of this connecting frame. Since this connecting pin does not move below the coin tube during the dispensing operation of the slide plate, muddy water or the like attached to the coins does not adhere to the connecting pin. Therefore, there is an advantage that muddy water or the like does not solidify and interfere with the connection/release operations of the connection pins.

In addition, since the protruding piece presses the connecting frame of the slide plate during the return trip of the slide plate, the shear stress applied to the connecting pin by the slide plate and selector is reduced, which has the advantage of preventing damage to the connecting pin due to long-term use. has.

Furthermore, when the slide plate returns to the standby position, the front end of the slide plate is regulated by the position regulating member, and the rear end of the slide plate is regulated by the protruding piece of the selector, so that the selector and the slide plate are in the predetermined position. Fixed. This has the advantage that the holes through which the connecting pins are inserted can be properly opposed to each other, and the connecting operation of the connecting pins can be performed reliably.
