Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coin passage width adjusting device for a coin processing machine for adjusting the width of a coin passage into which coins are fed by a feeding means according to the type of coins to be processed.

A conventional coin processing machine has, for example, a coin passage width adjusting device 1 as shown in the first diagram. This adjustment device 1 controls the passage width regulating members 2 and 3 for coins fed from an appropriate supply means.
In order to perform processing such as sorting and counting in the coin passage 4 whose passage width is determined by the coin passage 4, the width regulating member 2 is moved in accordance with all types with respect to the width regulating member 3 which is fixed in position.

In other words, the width regulating member 2 includes a guide mechanism (not shown),
It is made movable in the direction of expanding the passage width while maintaining a parallel relationship with the width regulating member 3 using a tension spring (not shown);
The contact portion at the end contacts one side of the Z-polygonal plate cam 6 and is brought to the stop position A.

The camshaft 5 to which the plate cam 6 is fixed is supported at the tip of a swinging piece 7A, and the base end of the swinging piece 7A is supported by a support bracket 7B with a support shaft 7C. is biased against the support bracket 7B by a tension spring 7D, and a stopper 7E also positions the swinging piece 7A relative to the support bracket 7B. In addition, stopper 7E
When the swinging piece 7A swings around the support shaft 7C in the direction away from the support bracket 7B, the plate cam 6 also moves away from the regulating member 2.
On the other hand, the width regulating member 2 is moved by a tension spring (not shown) toward the direction gate where it comes into contact with the plate cam 6, so that the passage width is expanded. However, the tension spring 7D has a very strong spring force, so when processing coins or changing denominations,
The stopper 7E remains in contact with the support bracket 7B, and the swinging piece 7A is not swung. Further, a path starting end bottom plate (not shown) and a path end bottom plate 9 are provided on the bottom of the passage at the starting end and the terminal end of the coin path j.
A sorting groove 4A for excluding small-diameter coins is provided in the middle area of the passage.In order to form the groove 4A, the width regulating member 2
, 3 are fixed to the lower surfaces of the sorting shelves 2'', 3'', and the portions of the sorting shelves 2'', 3'' facing inside the passageway are fitted with the width regulating member 2.
, 3 by a predetermined dimension. When sorting and counting coins using a coin processing machine having the coin passage width adjusting device ± and coin passage (as described above), the following problems occur. occurs.

Generally, some coins of the denomination to be processed are worn out or deformed, and such coins are removed from the sorting groove 4A while passing through the coin passage ±, but due to the degree of wear, deformation, etc., the coins are transferred to the sorting groove 4A. The sorting shelf board 2 does not fall completely.
It may get stuck between `` and 3''.

If subsequent rejected coins are also clogged due to such a jammed coin, it is possible to determine whether the coin is clogged within the coin passage 4 and perform removal work. However, there are many cases where subsequent rejected coins are rejected without being affected by the jammed coins, and in that case, the machine operator must move the sorting shelf 2'',
The jammed coins are not noticed between 3". In this situation, a problem arises when you want to complete the sorting and counting process for that denomination coin and start the sorting and counting process for the next denomination coin. First,
Coin passage 1 to match the diameter of the coin of the denomination you want to process next.
In order to change the width, when the denomination knob 5A is rotated, the camshaft 5 is rotated. However, since the plate cam 6 is polygonal, when rotating from one side to the other side, the plate cam 6 that was in contact with the width regulating member 2 makes surface contact with the other side through point contact at the apex of the polygon. will be done. Therefore, the width regulating member 2 is necessarily moved in the direction in which the passage width is narrowed, and then moved in the direction in which the passage width is widened, and is positioned at a position corresponding to the diameter of the other denomination coin. As mentioned above, when a coin is sandwiched between the sorting shelves 2'' and 3'', the width regulating member 2 is always moved in the direction of narrowing the passage width when the plate cam 6 rotates. Sorting shelf board 2″ fixed to member 2
The coins are also moved in the direction where the width of the passage becomes narrower, and the jammed coins are pressed against the sorting shelf board 3'', deforming and damaging them and making them unusable coins.

Further, the plate cam 6 itself cannot be rotated due to the clogged coin, and if it is forced to rotate, the plate cam, cam shaft 5, and knob 5A will be damaged. Also, when the sorting groove 4A is clogged with coins, by pressing the knob 5A, the swinging piece 7B moves to the support shaft 7 via the camshaft 5.
The plate cam 6, the width regulating member 2, and the sorting shelf board 2'' are moved in the direction of widening the passage width by being swung counterclockwise around C, thereby ensuring that the jammed coins enter the sorting j groove 4A. Exclusion is made.

However, since the tension spring force of the tension spring 7D is strong, a strong force is required. Furthermore, the coin handling machine has many adjustment points, and even if an attempt is made to adjust them by interlocking them with the camshaft 5 on which the denomination pick 5A is provided, the camshaft 5 itself will be moved. Therefore, interlocking adjustment of other adjustment points becomes difficult. The present invention has been developed in view of the above-mentioned problems. Coins to be processed are sequentially fed into a coin passage by a supply means, and processing such as counting is performed while the coins are conveyed in a line in the coin passage. , the coin passage has a pair of passage width regulating members defining a passage width, at least one of which is movable in the passage width direction, and the movable passage width regulating member is positioned at a predetermined position. In a coin processing machine equipped with a passage width adjustment cam that changes and sets the passage width to a passage width corresponding to the diameter of coins to be processed, the passage width adjustment cam is attached to a cam shaft rotatably held at a fixed position, A cam surface consisting of a plurality of passage width determining surface portions made of concentric circular arc surfaces, and a recessed portion provided between the passage width determining portions and having a smaller distance from the camshaft than the adjacent passage width determining surface portions. A cam follower provided on the movable passage width regulating member or a member that moves integrally with the movable passage width regulating member adjusts the passage width regulating member to enlarge the passage width. It is an object of the present invention to provide a coin passage width adjusting device for a coin processing machine, characterized in that the device is pressed into contact with a biasing means that biases the coin in a direction.

Hereinafter, a case where an embodiment of the passage width adjusting device according to the present invention is applied to a coin counting machine will be described.

In FIG. 2, a rotating disk 13 is provided on the vertical coin counting machine platform so as to be rotatable in the direction of the arrow in a horizontal plane, and a coin passage 13 is tangentially oriented around the rotating disk 2.
has been extended. This coin passage 13 includes a pair of passage width regulating members 14 and 15, sorting shelf boards 18 and 19 fixed to the lower surfaces of each of the width regulating members 14 and 15, and a rotating disk 12.
It consists of a coin introduction passage (not shown) that introduces coins from the coin passage into the coin passage 13, an entrance portion of the coin passage 13 on the introduction passage bottom plate T, a coin conveyance belt mechanism (not shown) located above the coin passage 13, etc. be done. The aforementioned sorting shelf board 18
has a U-shape in which the starting end side and the terminal end side of the passage 13 protrude, and both protruding parts and the upper surface are connected to the passage starting end bottom plate part 1.
8a1 passage end bottom plate part 18b, and both parts 18a, 1
The upper surface of the edge between 8b serves as a sorting shelf 18c.

On the other hand, the sorting shelf 19 has a rectangular shape, the long side of which is slightly smaller than the distance between the bottom plate parts 18a and 18b of the sorting shelf 18, and the upper surface of the edge facing into the passage 13 is the part of the sorting shelf 19.
c. Therefore, a sorting groove 4A is formed between the sorting shelf parts 18c and 19c by both sorting shelf boards 18 and 19. In addition, for the passage width regulating members 14 and 15, the sorting shelf boards 18 and 19
is fixed to both members 14, 15 in such a manner that each end edge of each sorting shelf 18c, 19c facing inside the passage 13 protrudes a predetermined amount further inside the passage than the passage width regulating members 14, 15. Also, the top surface of the rotating disk ±I, the top surface of the introduction passage bottom plate T,
The upper surfaces of the sorting shelf boards 18 and 19 are substantially on the same plane. The width regulating member 14 and the sorting shelf board 1 located under the width regulating member 14
8 is integrally fixed to the upper surface of the support plate 16, and the width regulating member 15 and the sorting shelf board 19 located on the lower surface thereof are integrally fixed to the upper surface of the support plate 17.

In this embodiment, both passage width regulating members 14 and 15 that define the passage width of the coin passage 13 and sorting shelf boards 18 and 19 that are integrally fixed with each of them are movable on both sides of the passage 13, Therefore, both the support plates 16 and 17 are made movable, and in order to make this possible, they are inserted into and fixed to an opening formed in the bracket 16a of the support plate 16, and fixed to the bracket 17a of the support plate 17. A support rod 22 that slides in the opening 2 is fixed to the support plate 17 side with screws 23,
A support rod 24 that slides in a hole 16b on the support plate 16 side, an arm 26 having a cam follower 25 attached to the tip thereof, and a cam follower 27 attached to the support plate 16. An arm 28 attached to the tip is fixed to each. The cam follower 25 is pressed against the cam surface of the passage width adjusting cam 32 by a spring 30, and the cam follower 25
7 is pressed against the passage width adjusting cam 31 by a spring 29. When both cams 31 and 32 are rotated integrally by their cam shafts 33, the cam surface of the cam 32 causes the cam follower 25, arm 26, rod 24, support plate 17,
The sorting shelf board 19 and the width regulating member 15 are moved together, while the cam surface of the cam 31 moves the cam follower 27, the arm 28, the rod 22, the support plate 16, the sorting shelf board 18, and the width regulating member 14.
will be moved altogether. During this movement, the width regulating members 14 and 15
When the member 14 moves in the opposite direction, that is, when the member 14 moves in the direction of reducing the passage width (left direction in Figure 2), the member 15 also moves in the direction of reducing the passage width (right direction in Figure 2). When member 14 moves in the direction of passage width expansion (rightward in Figure 2), member 1
The cam 3 is also moved in the direction of expanding the passage width (to the left in FIG.
1 and 32 shapes are defined. Note that the width regulating member 14
, 15 in the width direction, the bottom plate portions 18a, 18b must always exist in a bridging state on the lower surface of the width regulating members 14, 15 at the starting and terminal ends of the passage 13, so that the width Between the lower surface of the regulating member 15 and the upper surface of the support plate 17, there are bottom plate parts 18a and 1, excluding the sorting shelf board 19 part.
A gap is formed through which 8b enters and exits. The passage width adjusting cams 31 and 32 are fixed to one end of a camshaft 33 and can be rotated by a knob 34 provided at the other end of the camshaft 33. This is a case where the passage width is manually expanded to remove jammed coins. It is also possible to change the denomination manually using this knob 34, or by directly connecting the camshaft 33 to the motor shaft 7, it is possible to automatically widen the passage width for removing clogged coins and change the passage width when changing the denomination. Changes can also be made. When rotating the camshaft 33 only manually or automatically in this way, the direction of rotation of the camshaft 33 can be freely selected.
In this embodiment, the hook shaft 33 is designed to be able to be rotated both manually and automatically, and when changing the denomination, the passage width can be changed by automatically rotating the cam with the motor M. A pin 35 is implanted in the member 34, and this pin 35 is connected to the drive motor M side. That is, motor shaft 3
Notch 37a of rotary connecting cam 37 fixed to the tip of 6
Insert the pin 35 into the cam 37, protrude the pin 38 from the cam 37 side, and engage the pin 38 with one end.
While attaching the other end to the pin 35, the camshaft 33
A spring 39 is provided to be wound around the pin 35 so that the pin 35 is always in contact with the engaging edge 37b at one end within the notch 37a, and the rotation of the cam 37 is transmitted to the camshaft 33 side. It's summery.

When changing the passage width due to changing the denomination of coins to be processed, rotate the motor shaft 36 clockwise (in the direction of the arrow in Figure 3).
The engagement edge 37a of the rotary connection cam 37 pushes the pin 35 to rotate the camshaft 33 together with the motor shaft 36 to change the passage width.

In addition, when a coin jam occurs during coin processing, the passage width can be expanded using the motor M to remove the jammed coins. In that case, the motor M is reversed by operating the jammed coin removal button, and the motor shaft 36 is rotated at a predetermined angle. This is done by rotating it to the left and then rotating it to the right to return to its original position. When removing jammed coins, the reason why the motor shaft 36 is reversed is that it is necessary to quickly return to the path width corresponding to the denomination coin being processed after removing the jammed coins, and the return rotation of the shaft 36 by clockwise rotation is quick. This is to return it to its original position. The left-rotating connecting cam 37 of the motor shaft 36- is rotated to the left so that the engaging edge 37b is connected to the pin 3.
However, the spring 39 keeps the pin 35 in contact with the engaging edge 37b.
5 is rotated, the operating member 34 is also rotated to the left, and as a result, the camshaft 33. The motor shaft 36 is rotated counterclockwise as a result, and as a result, the passage width is expanded. When the motor shaft 36 is subsequently rotated clockwise to return to its original position, the rotary connecting cam 37 is also rotated clockwise, and the engaging edge 37b pushes the pin 35. Then, the cam shaft 33 is rotated clockwise to return the cams 31 and 32 to the path width corresponding to the diameter of the denomination coin S being processed. Further, when manually expanding the passage width to remove jammed coins, the picking member 34 is rotated clockwise in FIG. 3.

In other words, when the motor shaft 36 is stopped, it is difficult to rotate due to the load on the gear head in the motor M, the cam 45a (described later), etc. Therefore, even if the gripping member 34 is rotated counterclockwise, the pin 35
Therefore, it is difficult to rotate the rotary connecting cam 37. On the other hand, when the gripping member 34 is rotated clockwise in FIG. 3, the gripping member 34 can be easily manually rotated within the movable range of the pin 35 within the notch 37a of the rotary connection cam 37. That is, in this case, the gripping member 34 can rotate independently of the motor shaft 36, and the reason for this is that the load applied to the gripping member 34 is
9 and the load on the camshaft 33 side only. Note that when the grip member 34 rotates clockwise, the spring force of the spring 39 is not so strong, so the clockwise rotation of the pin 35 does not rotate the motor shaft 36 clockwise, and the motor shaft 36 stops at the initial position. , the rotary connecting cam 37 is also in a stopped state, the pin 35 is separated from the engagement edge 37b, and the passage width is expanded by the cams 31 and 32 within the movable range of the pin 35 within the notch 37a of the cam 37. When you release your hand from the picking member 34,
The spring 39 rotates the camshaft 33 of the knob 3 to the left, and the pin 35 comes into contact with the engagement edge 37b of the cam 37 and stops.
Also, the motor M is driven, and the motor shaft 36 is rotated to the right in FIG.
To determine the rotational position of the cams 31 and 32 when changing the denomination in which the
From a positioning device P having five positioning cams 40, 41, 42, 43, 44 fitted for circles, 10 yen, and 5Cf3, and switches SWl to SW5 arranged corresponding to these cams. is determined by transmitting a signal to said motor M. That is, each of the cams 31 and 32 has a passage width determining surface portion, which is for each coin of 1 yen, 5 yen, 1 yuan, 5 yuan, and 10 yuan, at a position approximately symmetrical to the cam shaft 33, depending on the denomination. The cam followers 27 and 25 are also pressed against the passage width determining surface of each cam 31 and 32 at approximately symmetrical positions with respect to the cam shaft 33, so that the passage width is determined according to each coin. The motor is designed to rotate clockwise.

The cam 45a fixed to the motor shaft 36 is used to adjust the height of the coin guide 45 relative to the rotating disk. We are trying to ensure that only one coin can enter the coin passage smoothly.

Note that 46 is a support frame that supports both ends of the rods 22 and 24, and is erected on the machine stand; 47 is a support frame that supports both ends of the rods 22 and 24;
This is a star wheel that is moved integrally with the support plate 16 and faces the downstream area of the coin passage 13, and is positioned at the upper part of the center in the width direction of the passage 13, and is transported by a coin conveying belt that spans from the beginning of the passage to the end of the passage. The number of passing coins is counted by being forcibly rotated by the coin itself. In particular, the cams 31 and 3 fixed to the camshaft 33
2, as shown in FIG. 4, the width regulating members 14 and 15 are moved to predetermined positions on the cam surfaces of the cams 31 and 32 according to the diameter of the denomination coins to be processed. Passage width determining portions 48a1 and 48a2 consisting of concentric arcuate surfaces
, 48a3, 48a448a5 and 48b1, 48b
2, 48b3, 48b4, 48b, are formed,
The passage width determining surface portion 48a1 of the cam 31 and the passage width determining surface portion 48b1 of the cam 32 are provided at symmetrical positions with respect to the cam shaft 33, and are each used as a passage width determining surface portion for a 1 yen coin.
Similarly 48a2 and 48b2, 48a3 and 48b3, 48
a4, 48b4, 48ton and 48b5 are provided at symmetrical positions with respect to the camshaft 33, and are respectively for 5 yen coin and 10Cff3.
This is the passage width determining surface for coins, 1 old coins, and 5CfJ coins.

The order of the diameter of each denomination coin from small to large is 1 yen, 50 yen, 5
circle, 100P1], 10, the radius from the cam shaft 33 of the cam 31 and the cam 32 to the passage width determining surface is 48a4, 48a5, 48a2, 48a5, 48a1
and 48b4,481)3,48b2,48kg,4
The size increases in the order of 8b1. Further, in the cam 31, a relief cam surface 48a6 having a smaller diameter than any of the passage width determining surfaces is formed on the cam surface extending from the passage width determining surfaces 48a3 to 48a. Further, on the cam surface of the circumferential surface of the cam 32, between the passage width determining portions 48b1 and 48b2, and between 48b2 and 48b3.
, between 48b3 and 48b4, between 48b4 and 48b5, and between 48b5 and 48b1, and the radius from the camshaft 33 is the entire passage width setting surface portion 48b1.
- 811), each of which is formed with a concentric cam surface having a radius smaller than the radius of the recess 49 is formed. Each recess 49 of this cam 32 is used to expand the coin passage width, and if the coin passage 13 is clogged with coins, the tab sorting shelf 18,
19 or between the width regulating members 14 and 15, rotate the picking member 34 clockwise or rotate the motor shaft 36 of the motor M counterclockwise by a predetermined amount and then return clockwise rotation. As a result, the cams 31 and 32 are rotated to the right or left by a predetermined amount, thereby enlarging the passage width and returning it to the original passage width. For example, when the gripping member 34 is manually rotated clockwise, the cam follower 25, which was in pressure contact with the passage width determining surface portion 48b4 of the cam 32, moves into the recess 49 between the passage width determining surface portions 48b4 and 48b5 due to the clockwise rotation of the cam 32. Recess, cam follower 25, arm 26, rod 24, support plate 1
7. The sorting shelf board 19 and the width regulating member 15 are moved in the left direction in FIG. 2 in the direction of widening the passage width. Note that the notch 37a of the rotary connecting cam 37 has a sufficient angular range for the cam follower 25 to fall from the passage width determining surface into the adjacent recess 49, and even when the cam follower 25 falls into the recess 49, The pin 25 is located in the middle of the notch 37a. On the other hand, the cam follower 27 moves into the recess 49 of the cam 32, although the pressure contact position with the passage width determining surface 48■ changes as the cam 31 is rotated clockwise by the predetermined amount described above together with the cam 32. Even when the child 25 falls down, the cam follower 27 is still in pressure contact with the passage width determining surface portion 48a, and the cam follower 27, arm 28, support plate 16, sorting shelf board 18, and width regulating member 14 are Not moved. Therefore, the aforementioned movement of the sorting shelf board 19 and the width regulating member 15 in the passage width expanding direction expands the passage width, and the coins clogged in the passage 13 are removed from the sorting groove 4A. After that, when you release your hand from the gripping member 34, the spring force of the spring 39 causes the gripping member 34 and the camshaft 33 to return to the left rotation position, and the engaging edge 37 of the rotating connecting cam 37 that is currently stopped is rotated to the left.
The pin 35 comes into contact with b, the rotation of the camshaft 33 is stopped, and the passage width regulating member 15 returns to its original position, and forms the passage width before the passage width is expanded between it and the width regulating member 14 which is at rest. . As a supplementary note, the passage starting end bottom plate part 1) 8a of the coin passage 13
Alternatively, in the case of a machine in which coins are jammed at the upper surface of the bottom plate portion 18b at the end of the passageway, the jammed coins may be manually scraped into the sorting groove 4A while the passage width is expanded. Alternatively, when the passage width is expanded, a seven coin transport belt mechanism (shown in the figure) extending over the center upper surface in the width direction of the coin passage 13 from the beginning to the end of the passage is rotated in forward and reverse directions and ejected into the sorting groove 4A. Good too. Also, when removing jammed coins using motor M,
First, the motor shaft 36 is rotated to the left by a predetermined angle, and the engaging edge 37b of the rotary connecting cam 37 is moved away from the pin 35 in the opposite direction. However, due to the spring force of the spring 39, the pin 35
is rotated while maintaining the engagement state with the engagement edge 37b, and as a result, the camshaft 33 and the cams 31, 32 are also rotated to the left. At this time, the force follower 25 that was in pressure contact with the passage width determining surface part 48b4 of the cam 32 falls into the recess 49 between the passage width determining surface part 48b1 and the passage width determining surface part 48b3, and the sorting shelf board 19 and the width regulating member 15 is moved in the direction of passage width expansion. On the other hand, the cam follower 27, which was in pressure contact with the passage width determining surface portion 48b1 of the cam 31, is integrated with the cam 32 into the cam 31.
is rotated to the left by a predetermined amount, the relief cam surface 48a
6, cam follower 27, arm 28, support plate 1
6. The rod 22, sorting shelf board 18, and width regulating member 14 are also moved in the direction of widening the passage width. As a result, in this case, passage 13
Both sides in the width direction are enlarged, and jammed coins are removed from the sorting groove 4A. When the motor shaft 36 is subsequently rotated clockwise again by the motor M, the pin 35 is pushed by the engaging edge 37b of the rotary connecting cam 37, and the cam shaft 33 and cams 31, 32 are also rotated clockwise, causing the passage of the cams 31, 32 to be rotated clockwise. Width determination circuit 48a4, 4
With the cam followers 27 and 25 in pressure contact with the cam followers 8b4, the motor M1 motor shaft 36 and the cam shaft 33 are stopped, and the passage width regulating members 14 and 15 are also returned to their original positions and stopped. Also, when changing the denomination, the motor M1 motor shaft 36 rotates clockwise, and the engaging edge 37b of the rotary connection cam 37 pushes the pin 35 to rotate the cam shaft 33 clockwise, thereby determining the passage width of the cam 32. The cam follower 25 that was in pressure contact with any of the surface portions 48b1 to 48b5 necessarily falls into the adjacent recess 49 on the left side with respect to the clockwise rotation direction in FIGS. 3 and 4, and then falls into the other passage width determining surface portion. When the cam follower 25 falls into the recess 49, the cam follower 27, which was in pressure contact with one of the passage width determining surfaces 48a1 to 48a5 of the other cam 31, has its previous passage width determined. ．． The width regulating member 14 maintains a state of pressure contact with the constant surface portion, or is in a depressed state to the passage width determining surface portion with a small diameter, and the width regulating member 15 moves in the direction of increasing the passage width. Move in the direction of expanding the passage width.

As a result, the aisle width has been expanded! Naware, sorting shelf board 18,
Coins that have not been noticed due to being stuck between the slots 19 are removed into the sorting groove 4^. After this passage width is expanded, the passage width is changed to that of another denomination coin, so even if the change is to reduce the passage width, the sorting shelf board 18,
19. Coins that get stuck in the space and go unnoticed will not be deformed or damaged. In this way, when removing a jammed coin by manual operation using the picking member 34, when removing a jammed coin by rotating the motor M and the motor shaft 36 to the left, and when changing the denomination by rotating the motor M1 and the motor shaft 36 to the right, Cam follower 25
falls into the adjacent recess 49 from the passage width determining surface portion that was in pressure contact, and the width regulating member 15 and sorting shelf board 19 are thereby moved in the direction of expanding the passage width, and the width regulating member 14 at that time
is either in a constant position or in a state of movement in the direction of expanding the passage width, and as a result, the passage width is reliably expanded.

In this embodiment, an example of the passage width adjustment cam of the present invention is the passage width adjustment cam 32, an example of the contact part is the force follower 25,
An example of the camshaft of the passage width adjusting cam is shown as a camshaft 33. The cam follower 25 as a contact portion may be fixed to the width regulating member 15, but in this example, the member 15
It is attached via an arm 26 to a rod 24 that moves together with the rod 24. Next, the operation of this embodiment will be explained.

For example, when 1 yen coins are placed on the rotary disk 12 and counted, a 1 yen denomination setting button in a group of denomination/denomination setting buttons (not shown) is pressed with the power switch turned on.

As a result, the motor M and the motor shaft 36 rotate clockwise, and when the cam 40 presses the 1 yen switch SWl, the motor M
stops. In other words, if the coin passage 13 before selecting the 1 yen coin denomination is set to a passage width for a 5Cf3 coin, which has a larger diameter than a 1 yen coin, the cam follower 25 before denomination selection is set to the passage width for a 5Cf3 coin of 50P1 of the cam 32. The cam follower 27 is in pressure contact with the passage width determining surface portion 48 kg, and the cam follower 27 is in contact with the passage width determining surface portion 4 for 50 yen of the cam 31.
It is in pressure contact with 8a5. When the aforementioned motor M is rotated clockwise from this state, the cam follower 25 first falls into the recess 49 of the cam 32, and then the passage width determining surface 48b for one circle.
1, and after the cam follower 27 continues to be in pressure contact with the passage width determining surface 48a5 for 50PJ, at the time when the cam follower 25 rides on the passage width determining surface 48b1, the cam follower 27 reaches 1.
When the cam followers 25 and 37 have climbed onto the passage width determining surface portions 48a1 and 48a1, SWl is pressed and the motor M is stopped.
The rotation of the motor shaft 36, the connecting cam 37, the pin 35, the gripping member 3, and the camshaft 33 is stopped, and the cams 31 and 32 are also stopped. As a result, the width regulating members 14, 15 and the sorting shelves 18, 19 are set at predetermined positions that define the passage width and sorting groove width from 50P coins to 1 yen coins. As described above, during the movement to change the denomination, the cam follower 25 necessarily falls from the path width determining surface before the change into the adjacent recess first, so the width regulating member 15 and the sorting shelf board 19 are The cam follower 27 is moved in the direction of passage width expansion, and at this time, the cam follower 27 is maintained in pressure contact with the passage width determining surface portion before change, or is in a state of being depressed to a smaller passage width determining surface portion or a release cam surface, Therefore, the width regulating member 14 and the sorting shelf board 18 are either maintained at the positions before the change, or are moved in the direction of increasing the passage width, and as a result, the passage width is first enlarged from the passage width before the change, and then the desired gold The width of the passage was changed to one for seed coins, so the sorting groove 4 of the passage 13 was changed before the change.
The coins stuck in A are reliably ejected into the sorting groove 4A when the passage width is expanded as described above, and are ejected to the lower part of the machine by a chute (not shown) facing the sorting groove 4A and held there. In particular, the passage width adjusting cams 31 and 32 are arranged concentrically on the passage width determining surface portion 48a.
1-48A5 and 48b1-48kg, the cam rotates smoothly without requiring any force.

When the above settings are completed, press the start button and rotate the rotating disk 1.
The coins are rotated to move the coins near the outer periphery by centrifugal force, and the coins are aligned by the coin guide 45 so as not to be piled up, and then passed through the coin introduction passage (not shown) to the coin passage 1.
Send it to 3.

While passing through the passage, the coins are judged to be genuine or false based on their diameter, thickness, etc., are rotated by a star wheel 47, counted, and flowed down. However, if coins get stuck in this passage width, the operator can manually remove the coins from the picking member 34.
By rotating clockwise, the cam follower 25 moves into the recess 49.
The passage width is expanded by the action of the spring 29.

Due to this passage expansion, the jammed coins will fall and be removed. When the hand is released from the gripping member 34, the camshaft 33 of the gripping member 3 rotates counterclockwise and returns to its original position due to the spring force of the spring 39. Also, if you want to perform this exclusion operation automatically,
When the operator presses a switch (not shown), the motor M is reversely rotated, and the same effect as described above is performed by the counterclockwise rotation of the motor shaft 36 and the rotation of the pin 35 by the spring 39 to follow the rotational connection cam 37.

Also, by rotating the motor M and the motor shaft 36 clockwise for return, the cam shaft 33 and cams 31 and 32 also return to their original positions.
Denomination coin processing can be resumed. In the above embodiment, the camshaft is rotated by rotating the camshaft by the motor M or by manually rotating the gripping member 34. However, as shown in FIG. A similar rotational action can be obtained by using a wheel 50, engaging a claw 51 with the wheel 50, and swinging a link 53 supported by a pin 52 with a solenoid 54.

Further, in the above embodiment, both of the width regulating members are moved by cams, but it goes without saying that only one of them may be moved.

In other words, in the case of this embodiment, the passage width regulating member 14,
The sorting shelf board 18 is fixed in position, the passage width regulating member 15 and the sorting shelf board 19 are movable, the cam 31 is eliminated, and the diameter from the cam shaft 33 of the passage width determining surface parts 48b1 to 481) of the cam 32 is fixed. It is sufficient to form concentric arcuate surfaces with diameters that match the passage widths for each denomination, and to form recesses 49 between the passage width determining surfaces.

In addition, when the passage width regulating member 15 and the sorting shelf board 19 are fixed, the cam 32 is omitted and the passage width determining surface portion 48 of the cam 32 is fixed.
The diameter from the cam shaft 33 of a1 to 48a5 is a concentric circular arc surface with a diameter that matches the passage width for each denomination, and a recess corresponding to the recess 49 of the cam 32 (for example, 48a6
It is sufficient to provide a recessed portion such as the above.

As described above, the present invention sequentially feeds the coins to be processed into the coin passage by the supply means, and performs processing such as counting while the coins are being conveyed in a line in the coin passage.
The coin passage has a pair of passage width regulating members that define the passage width, at least one of which is movable in the passage width direction, and the movable passage width regulating member is positioned at a predetermined position for processing. A coin store equipped with a passage width adjustment cam that changes and sets the passage width to correspond to the diameter of coins to be exchanged. In the industrial machine, the passage width adjusting cam is attached to a cam surface that is rotatably held at a fixed position, and is provided between a plurality of passage width determining surfaces made of concentric arcuate surfaces and each of the passage width determining surfaces. , a cam surface comprising a concave portion having a smaller distance from the camshaft than the adjacent passage width determining surface portion, and the cam surface of the passage width adjusting cam is provided with the movable passage width regulating member or A coin processing machine, characterized in that a cam follower provided on a member that moves integrally with the member is brought into pressure contact with the passage width regulating member by a biasing means that biases the passage width regulating member in a direction of expanding the passage width. Since this is a coin passage width adjustment device, when changing the passage width due to a change in coin denomination,
The passage width is first expanded and then changed to the desired passage width, so even if there is a jammed coin between the sorting grooves and the passage width is changed without noticing the jammed coin, the width between the sorting grooves will be changed. The coins that were stuck in the machine are surely removed from the sorting groove,
There have been no cases of deforming jammed coins, making them unusable, or damaging the cam, camshaft, etc. Also, when you notice a jammed coin during coin processing and remove it, the passage width adjustment cam is used. When the contact part that was in contact with the passage width determining surface part is brought into contact with the adjacent recessed part by rotating the cam, the passage width is expanded and the jammed coins can be removed.After removal, when the cam is rotated back to its original position, The passage width is restored to the width corresponding to the coins to be processed, making it easy to remove jammed coins, and since the cam shaft of the passage width adjustment cam is always positioned at a fixed position, there is no need for adjustment. It has extremely excellent effects such as easy adjustment of interlocking with the mechanical part.
