Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is incorporated in a vending machine, and mainly 500 yen coins are arranged in a line in a vertical path in a vertical passage having a rectangular cross section and are held by gravity so that they can be dropped. The present invention relates to a coin dispensing device that is dispensed one by one based on a command for dispensing or returning change.

[0002]

2. Description of the Related Art A conventional example will be described with reference to FIGS. FIG. 8 is a front view seen from the outside of the passage at the time of holding, FIG. 9 is a rear view seen from the inside of the passage at the time of holding, and FIG. 10 is a side view at the time of holding. In this conventional example, blocking pins are provided at both ends of a seesaw-like swinging member, and the blocking pins on both sides alternately go out and pull out in a manner to traverse the passage in the thickness direction. Then, the coins to be ejected at the bottom end are blocked / released, or the preceding standby coins are released / blocked to eject one coin at a time.

In FIG. 8, a rotating portion 32 corresponding to a seesaw base is pivotally supported by a bearing 35 so as to be swingable. At each of the upper and lower ends of the rotating portion 32, a payout gate 30 for blocking and releasing the coin at the lowest end, and a standby for blocking and canceling the standby coin immediately before the coin to be dispatched 9 As shown in FIG. 10, the gate 31 is rotatably connected. Each of the gates 30 and 31 for throwing out and waiting has a pin projecting from the left and right sides of its tip, and these pins project and pull out from the inside of the passage 34. Rotating part
A lever 33 is provided at the center of 32 so as to project (see FIG. 10), and this engages with a driving frame 38 that is guided so as to be vertically reciprocable and straight. The driving frame 38 is driven to reciprocate linearly by the urging force of the solenoid 36 and the spring 37. Therefore, as shown, when the solenoid 36 does not operate, the driving frame 38 is
It is positioned at the bottom by the bias of 37, and the ejection gate 30
Will block all reserved coins, including the lowest to-be-disposed coins. When the solenoid 36 operates based on the command, the driving frame 38 is pulled up against the bias of the spring 37 and positioned at the uppermost end. In the process, the blocking of the dispensing gate 30 is released and the expected coins are to be dispensed, and the standby gate 31 blocks all the reserved coins including the preceding standby coin. The disappearance of the command causes the solenoid 36 to return to the initial state, and this is repeated thereafter, and coins 9 are dispensed one by one.

[0004]

The conventional example has the following drawbacks. One is the gates 30 and 31 for throwing out and waiting, and the rotating part.
Due to the structure of the lever 32 and the lever 33, the size of the coin in the thickness direction becomes large, and the other is that the main constituent members are the throw-out and standby gates 30 and 31 and the rotating portion 32. In terms of
It takes time to assemble them.

The problem to be solved by the present invention is to solve the above-mentioned problems of the prior art, to save space, particularly to reduce the size of coins in the thickness direction, reduce the number of parts, and simplify assembly. It is to provide a coin dispensing device capable of reducing costs.

[0006]

According to another aspect of the present invention, there is provided a coin dispensing device in which coins can be dropped by gravity in a passage having a rectangular cross section having two sides each having a dimension corresponding to a diameter and a thickness thereof. The device is a device that is ejected based on a command while being held in a circular shape, in which the ejecting and standby cam grooves are located in the passage direction, the former on the downstream side, and the latter on the upstream side. A driving frame that is installed in parallel and that travels straight forward and backward in a fixed stroke in parallel with the passage direction based on one command; a driven arm that has a driven pin that engages with the ejection cam groove at one end and a passage A blocking arm for projecting coins that protrudes in a transverse direction is fixedly connected to the other end of the blocking arm, and the blocking pin is connected to the axis of the blocking pin at this connection point. A coin blocking / releasing switching thrower supported rotatably around parallel fixed axes And a standby arm having a driven pin at one end that engages with the standby cam groove, and a standby coin that protrudes across the passage in the thickness direction A blocking arm having a blocking pin at one end is fixedly connected at each of the other ends, and is supported rotatably around a fixed axis parallel to the axis of the blocking pin at this connection point. It has a standby gate for switching coins to be blocked / released. In the initial stage, the blocking pin of the dispensing gate is positioned so as to block the coins to be ejected, and the blocking pin of the standby gate is located in front of the coin to be ejected. The standby coin is positioned so that it can be released, and by one reciprocating straight movement of the driving frame based on one command, the blocking pin of the ejection gate returns to the blocking position after releasing the planned coins to be ejected, and the blocking pin of the standby gate on the other Returns to the release position after blocking the standby coin It is formed.

According to a second aspect of the present invention, there is provided a coin dispensing device according to the first aspect.
In the device described in (1), the direction of the pressing force based on the pending coin load acting on the corresponding blocking pin, which is received by the corresponding driven cam grooves for the driving frame and the standby cam groove,
The cam groove and the driven pin are formed at right angles to the rectilinear direction of the driving frame, and the acting portions of the pressing force are in surface contact with each other.

A coin dispensing device according to a third aspect of the present invention is the first aspect.
Alternatively, in the device described in 2, the direction of the passage is vertical.

[0009]

In the coin dispensing device according to any one of claims 1 to 3, the driven pin of the dispensing gate is engaged with the dispensing cam groove of the driving frame at the initial position and the blocking pin is dispensed. In addition to blocking the planned coin, the driven pin of the standby gate engages with the standby cam groove, and the blocking pin releases the standby coin immediately before the planned coin. Therefore, all the reserved coins including the expected coins are blocked and held by the blocking pin of the dispensing gate. When the driving frame goes straight forward based on one command, the blocking pin of the ejection gate is switched and positioned to release the coins to be dropped and fallable on the one hand, and the blocking pin of the standby gate on the other hand It switches and positions so that the previous standby coin can be blocked. Therefore,
Only one coin to be thrown is thrown. Next, when the driving frame goes straight in one backward direction, the blocking pin of the ejection gate is switched and positioned so that the next coin to be ejected can be blocked, and the blocking pin of the standby gate can release the next standby coin on the other hand. After switching and positioning, it returns to the initial state.

Particularly, in the coin dispensing device according to claim 2,
Since the direction of the pressing force received from the driven pins corresponding to the cam grooves for ejecting and waiting for the driving frame is at right angles to the rectilinear direction of the driving frame, the pressing force may affect the rectilinear force of the driving frame. Since the number is small and each cam groove is in surface contact with each driven pin, the value of the pressing force per unit area becomes small.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a coin dispensing device according to the present invention will be described below with reference to the drawings. First, the basic operation of the embodiment will be described with reference to the front view of the main portion of the embodiment shown in FIG. 1 during the holding time and the front view of the main portion of the embodiment shown in the FIG. Here, for the sake of convenience, only the minimum members necessary for explaining the operation are shown. In FIG. 1, two coins 9 that can be dropped and are in a hold state are shown in a passage (not shown). The lower side is a planned to-discard coin 9 and the upper side is a coin 9 waiting to be ejected. In reality, there are further coin rows above, but they are not shown here. The reason why the coin 9 on the lower side is held without being dropped is that the coin 9 on the lower side is blocked by the blocking pin 14 belonging to the dispensing gate 10. At this time, the upper coin 9 is not blocked by the blocking pin 24 belonging to the standby gate 20 (released state).

Here, the ejection gate 10 has a driven arm 11
And the blocking arm 13 are fixedly connected to each other at one end, and this connecting point forms a connecting shaft 15 perpendicular to the plane of the drawing. The connecting shaft 15 is rotatably supported by a bearing (not shown). On the other end of the driven arm 11, follow the driven pin.
12 is provided so as to project to the front side at a right angle to the paper surface. At the other end of the blocking arm 13 (located on the lower side), a blocking pin 14
Is provided so as to project to the other side at right angles to the paper surface, and this blocking pin 14 blocks the coin 9 to be thrown out from falling. Similarly, in the standby gate 20, the driven arm 21 and the blocking arm 23 are fixedly connected to each other at one end thereof, and this connecting portion forms a connecting shaft 25 perpendicular to the paper surface. This connecting shaft 25
It is rotatably supported by a bearing (not shown). A driven pin 22 is provided at the other end of the driven arm 21 so as to project to the front side at a right angle to the paper surface. The other end of the blocking arm 23 (
A blocking pin 24 is provided at an upper position (a little to the right of the upper side) so as to project to the other side at a right angle to the paper surface, and the blocking pin 24 does not block the waiting coin 9.

The drive frame 3 moves straight up and down in a constant stroke in a vertical direction based on a command, and is in the lower limit position before the command. The driving frame 3 has two cam grooves 1,
2 are arranged side by side in the vertical direction. The lower cam groove 1 is for ejection,
The upper cam groove 2 is for standby. Ejection gate in cam groove 1
The driven pin 12 of 10 is engaged, and the driven pin 22 of the standby gate 20 is engaged with the cam groove 2. Here, based on the command, first, when the driving frame 3 goes straight upward for a certain stroke, as shown in Fig. 2, the ejection gate 10 is counteracted through the engagement between the cam groove 1 and the driven pin 12. Rotating clockwise, the blocking pin 14 unlocks the lower coin 9 and causes it to fall or be ejected. At the same time, the standby gate 20 rotates counterclockwise through the engagement of the cam groove 2 and the driven pin 22, the blocking pin 24 blocks the upper coin 9, and all further coin rows Put on hold. Next, when the drive frame 3 goes straight downward for a certain stroke and returns to the initial state, the state returns to the state shown in Fig. 1 and the block 9 of the previous waiting coin 9 (upper side) is released by the block pin 24. It drops a little and is blocked by the blocking pin 14 to become the next planned coin 9 (lower side). Thereafter, this is repeated and coins are thrown out one by one.

Here, it should be noted that the relative position between the driven pin 12 and the cam groove 1 in FIG. Exit gate
A moment based on the pending coin load acting on the blocking pin 14 acts on 10 and the driven pin 12 applies a pressing force to the contact portion of the cam groove 1, but the direction of this pressing force is shown in the figure. As described above, the drive frame 3 is at a right angle to the straight traveling direction (vertical direction). Therefore, this pressing force rarely affects the rectilinear force of the driving frame 3. Moreover, the driven pin 12 and the cam groove 1 are chamfered at the contact portion, and the surfaces are in surface contact with each other. By this surface contact, the value of the pressing force per unit area can be reduced, which is effective against wear. Similarly, the relationship between the driven pin 22 and the cam groove 2 when the waiting gate 20 in FIG. 2 receives the load of the holding coin is also devised, and the driven pin 22 is added to the contact portion of the cam groove 2. The direction of the pressing force is perpendicular to the direction in which the driving frame 3 goes straight. Moreover, the driven pin 22 and the cam groove 2 are chamfered at the contact portion, and the surfaces are in surface contact with each other.

Now, a general description of the embodiment will be given.
First, the case of holding coins (prior to the dispensing) will be described with reference to FIGS. 3 to 5. 3 is a front view of the embodiment seen from the outside of the passage, FIG. 4 is a rear view of the same seen from the inside of the passage, and FIG. 5 is a side view of the embodiment. In FIG. 3, 6
Is a passage for coins, which has a rectangular cross section having dimensions of two sides corresponding to the diameter and thickness of the coin, and is arranged in the vertical direction. The driving frame 3 is connected to the output shaft of the solenoid 4 and is urged downward by the spring 5. The bearing 8 is attached to the outside of the passage 6 (on the front side of the paper), and the gates 10 and 20 for ejecting and waiting are attached to the connecting shafts 15 and 25, respectively.
It is pivotally supported by. Gates for throwing and waiting 10,20
The blocking pins 14 and 24 of the above pass through the grooves 7a and 7b formed in the front wall of the passage 6 and project in such a manner as to traverse the internal space of the passage 6 in the coin thickness direction. In the state shown in the figure, the solenoid 4 is not operated, and the driving frame 3 is positioned at the lower limit position by the spring 5. At this time, as shown in Fig. 4, coin 9
Are blocked by the blocking pin 14 of the ejection gate 10 and are held in a row so as to be vertically movable in a manner similar to a natural fall (see FIG. 1). Note that FIG. 5 shows the positional relationship between the blocking pins 14 and 24 and the driven pins 12 and 22 of the gates 10 and 20 for ejecting and waiting.

Next, the coin dispensing operation will be described with reference to FIGS. 6 and 7. FIG. 6 is a front view of the embodiment as seen from the outside of the passage at the time of casting, and FIG. 7 is a rear view of the embodiment as seen from the inside of the passage as at the time of casting. In FIG. 6, the solenoid 4 is activated by a command to pull the driving frame 3 upward and position it at the upper limit position. By the raising operation of the driving frame 3, the gates 10 and 20 for throwing out and waiting rotate in the counterclockwise direction in the figure, and the blocking pin 14 releases the coins to be thrown at the bottom end to be thrown out, The blocking pin 24 blocks the standby coin, which is one coin before the thrown coin (see Fig. 7). When the command disappears, Fig. 3 to Fig. 5
Return to the initial state of.

From the above structure, structurally space saving,
In particular, the size of the coin in the thickness direction can be reduced, and the size of the entire device can be reduced. This is a gate 1 for throwing out and waiting
This is because 0 and 20 rotate around an axis perpendicular to the thickness direction of the passage 6, and the blocking pins 14 and 24 swing inside the passage 6. Further, the cost can be reduced by reducing the number of parts and simplifying the assembly. That is, the main parts corresponding to the three points of the ejection gate 30, the standby gate 31, and the rotating portion 32 in the conventional example are the ejection gate 10 and the standby gate.
20 points, and the corresponding cam grooves 7a, 7 of the drive frame 3
Since it has a structure that fits into b, assembly is simple. On the other hand, in the conventional example, the rotating unit 32 and the gates 30
Since 1 and 1 have a shaft insertion structure for rotational connection, troublesome work is required for that.

[0018]

In the coin dispensing device according to any one of claims 1 to 3, the driven pin of the dispensing gate is engaged with the dispensing cam groove of the driving frame at the initial position, and the blocking pin thereof is provided. Block the planned to-dispatch coin, and the follower pin of the standby gate engages with the standby cam groove, and the block pin releases the one-preceding coin to be projected. Therefore, all the reserved coins including the expected coins are blocked and held by the blocking pin of the dispensing gate. By the forward movement of the driving frame based on one command, the blocking pin of the ejection gate is switched and positioned to release the coin to be ejected and to drop,
On the other hand, the blocking pin of the standby gate is switched and positioned so as to be able to block the standby coin immediately before the coin to be ejected. Therefore, only one coin to be thrown out is thrown out. Next, when the driving frame goes straight in one backward direction, the blocking pin of the ejection gate is switched and positioned so as to block the next planned coin, and the blocking pin of the standby gate can release the next standby coin on the other side. Switched to and positioned to return to the initial state.
As a result, the following effects can be expected. (1) Structurally space can be saved, especially the size of the coin in the thickness direction can be reduced, and the size of the entire device can be reduced. This is due to the structure in which the gates for throwing out and waiting rotate about an axis perpendicular to the thickness direction, and the blocking pin swings inside the passage. (2) The cost can be reduced by reducing the number of parts and simplifying the assembly. That is, the main parts are two points of the ejection gate and the standby gate (three points in the conventional example), and since the structure is fitted, the assembly is easy (in the conventional example, a rotatable connecting portion is provided. It is necessary to insert the shaft and adjust it.) (3) One coin is reliably ejected according to one command, and the reliability is high. (4) Even if an abnormality occurs in the linear motion of the drive frame, the safety function works so as to prevent continuous withdrawal of held coins. The items (3) and (4) are basically the same as the conventional example, but they are more reliable.

Particularly, in the coin dispensing device according to claim 2,
Since the direction of the pressing force received from the driven pins corresponding to the cam grooves for ejecting and waiting for the driving frame is at right angles to the rectilinear direction of the driving frame, the pressing force may affect the rectilinear force of the driving frame. Since the number is small and each cam groove is in surface contact with each driven pin, the value of the pressing force per unit area becomes small. Therefore, improvement in operational reliability is supported, and wear due to sliding between the driven pin and the cam groove can be reduced.

Particularly, in the coin dispensing device according to claim 3,
Since the passages are arranged in the vertical direction, space saving of the device itself and the host device in which the device is incorporated is supported.
