Description

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

A conventional coin processing machine has a curing passage width adjusting device 1 as shown in FIG. 1, for example. This adjustment device 1 is
In order to perform processing such as sorting and counting of coins fed from an appropriate supply means through a coin passage 4 whose passage width is determined by passage width regulating members 2 and 3, all types of coins are sorted and counted by the width regulating member 3, which is fixed in position. The width regulating member 2 is moved accordingly.

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

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 urged against the support bracket 7B by a tension spring 7D, and the swing piece 7A is positioned with respect to the support bracket 7B by a stopper 7E. Note that when the stopper 7E swings the swinging piece 7A around the support shaft 7C in the direction away from the support bracket 7B, the plate cam 6 is also moved in the direction away from the regulating member 2, while the width regulating member 2 Since it is moved in the direction of contacting the plate cam 6 by a tension spring (not shown), the passage width is expanded. However, since the spring force of the tension spring 7D is very strong, the stopper 7E remains in contact with the support bracket 7B during coin processing and when changing denominations, and the swinging piece 7A does not swing. In addition, a passage start end bottom plate (not shown) and a passage end bottom plate 9 are provided on the bottom of the passage at the starting end and the terminal end of the coin passage 4.
A sorting groove 4A for excluding small diameter coins is provided in the middle area. In order to form the groove 4A, sorting shelf boards 2'', 3'' are fixed to the lower surfaces of the width regulating members 2, 3, and each sorting shelf board 2'',
The inwardly facing portion of the passage 4 of 3" projects inward from the width regulating members 2 and 3 by a predetermined dimension. A coin processing machine having the hardening passage width adjusting device 1 and the coin passage 4 as described above. Therefore, the following problems arise when sorting, counting, etc. coins.

Generally, some coins of the denomination to be processed are worn or deformed, and such coins are passed through the coin passage 4.
During the process, the particles are removed from the sorting groove 4A, but due to their degree of wear and deformation, they may not completely fall into the sorting groove 4A, and may become stuck between the sorting shelves 2'' and 3''. If subsequent rejected coins are also clogged due to such jammed coins, it is possible to remove the coins jammed in the coin passage 4. However, there are many cases where subsequent rejected coins are rejected without being affected by the jammed coins mentioned above, and in that case, the machine operator must remove the jammed coins caught between the sorting shelves 2'' and 3''. I don't notice it. In this situation, a problem arises when you want to finish sorting and counting the coins of that denomination and start sorting and counting the next coin. In order to change the width of the passage 4, when the denomination knob 5A is rotated, the camshaft 5 is rotated.
However, since the plate cam 6 is polygonal, when the plate cam 6 is in contact with the width regulating member 2, when it rotates from one side to the other side, it comes into surface contact with the other side through point contact by the apex of the polygon. That will happen. Therefore, the width regulating member 2 is necessarily moved in the direction in which the passage width becomes narrower, and then moved in the direction in which the passage width becomes wider, and is positioned at a position corresponding to the other denomination coin size. If a coin is sandwiched between the aforementioned sorting shelves 2'' and 3'', the width regulating member 2 is always moved in the direction in which the passage width becomes narrower when the plate cam 6 rotates. The sorting shelf board 2'' fixed to is also moved in the direction of narrowing the aisle width, and the jammed coins are pressed against the sorting shelf 3'', causing deformation and damage.
Make the coin unusable. cormorant.

Further, the plate cam 6 itself cannot be rotated due to the clogged coin, and if it is forced to rotate, the plate cam 6, 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 the removal of jammed coins into the sorting groove 4A. will be done.

However, since the tension spring force of the tension spring 7D is strong, a strong force is required. In addition, there are many adjustment points in the coin processing machine, and even if you try to adjust them by interlocking them with the camshaft 5 on which the denomination knob 5A is installed, the camshaft 5 itself is moved, so it is difficult to adjust the other adjustment points in conjunction with each other. becomes. In particular, there has recently been a demand for fully automatic adjustment of parts of coin handling machines that require adjustment using motors. Therefore, it is desirable that the camshaft 5 also be rotated by a drive shaft driven by a motor, but as described above, since the camshaft 5 moves, it cannot be rotated by the drive shaft. Therefore, it is attached to a camshaft that is rotatably held at a fixed position, and is provided with a plurality of passage width determining surfaces made of concentric circular arc surfaces, and each of the passage width determining surfaces is provided with a plurality of passage width determining surfaces. The cam surface has a concave portion having a small distance from the cam shaft, and the cam follower provided on the cam surface is a movable passage width regulating member or a member that moves integrally with the member. We have devised a device that includes a passage width adjusting cam that is brought into pressure contact with a passage width regulating member by a biasing means that biases the passage width in the direction of expanding the passage width, and in which the camshaft is directly connected to a drive shaft driven by a motor.

According to this device, when changing the denomination, the passage width is first expanded and then changed to the passage width corresponding to the desired denomination coin diameter, so coins that are stuck in the sorting groove 4A are automatically removed. It is convenient that it is done.

However, if coins become jammed in the passage during processing such as sorting and counting coins, and it is desired to remove the jammed coins, it is also necessary to operate the motor to rotate the drive shaft and camshaft. It is good if the rotation of this motor and drive shaft can remove jammed coins, but when coins get jammed in the passageway during processing, many coins are often stuck in the passageway, and all the jammed coins are removed. difficult to exclude. Even if you try to widen the passage width by rotating the camshaft by hand, the drive shaft does not rotate easily due to the load of the motor's gear mechanism, other adjustment cams, etc., and the passage width cannot be expanded manually. do not have. The present invention has been made in consideration of the above points, and includes, in addition to the passage width adjusting cam and camshaft described above, a drive that is rotated in one direction by a motor and stopped at a predetermined angle position when changing the passage width. A shaft, a connecting member fixed to the drive shaft and having an engagement edge formed thereon, and a connecting member fixed to the camshaft side to be rotated together with the camshaft, and for driving rotation in one direction of the drive shaft when changing the passage width. an engaged member that is pushed by the engaging edge of the connecting member to rotate the camshaft integrally with the drive shaft; an engaging spring that engages the engaged member with the engaging edge of the connecting member; The camshaft is provided on the camshaft, and the camshaft is manually rotated in a direction in which the engaged member is separated from the engagement edge of the connecting member, and the rotation brings the contact portion into contact with the concave portion of the passage width adjustment cam to enlarge the passage width. a camshaft rotated in conjunction with a drive shaft rotated by a motor, which can be manually rotated by the operation member to expand the passage width. An object of the present invention is to provide a curing passage width adjusting device.

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

In FIG. 2, a rotating disk 12 is provided on a machine base 11 of a coin counting machine 10 so as to be freely rotatable in the direction of the arrow in a horizontal plane, and a coin passage 1 extends tangentially around the rotating disk 12.
3 has been extended.

This coin passage 13 has a pair of passage width regulating members 14 and 15.
and the sorting shelf boards 18 and 19 fixed to the lower surfaces of each of the width regulating members 14 and 15, and the introduction passage bottom plate T of the coin introduction passage (not shown) that introduces coins from the rotating disk 12 to the coin passage 13. Coin passage 13 entrance part and coin passage 1
3, and a coin conveying belt mechanism (not shown) located above the coin conveying belt mechanism. 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 the upper surfaces of both protrusions form the passage starting end bottom plate part 18a1 and the passage terminal end bottom plate part 18.
b, and the upper surface of the edge between both parts 18a and 18b is used as a sorting shelf board 18c. On the other hand, the sorting shelf 19 has a rectangular shape, and its long side is slightly smaller than the distance between the bottom plates 18a and 18b of the sorting shelf 18, and the upper surface of the edge facing into the passage 13 serves as the sorting shelf 19c. . Therefore sorting shelf 18,1
9 forms a sorting groove 4A between the sorting shelves 18c and 19c. In contrast to the passage width regulating members 14 and 15, the respective ends of the sorting shelf boards 18c and 19c facing the inside of the passage 13 are located inwardly of the passage 13 from the passage width regulating members 14 and 15. Both members 1 have a quantitative protruding relationship.
It is fixed at 4,15. Further, the upper surface of the rotary disk 12, the upper surface of the introduction passage bottom plate T, and the upper surface of the sorting shelf plates 18 and 19 are substantially on the same plane. The width regulating member 14 and the sorting shelf board 18 located on its lower surface are 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 its lower surface are fixed to the supporting plate 17. is integrally fixed to the top surface of the

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. Both of the support plates 16 and 17 are movable, and in order to make this possible, they are inserted into an opening 20 formed in the bracket 16a of the support plate 16 and fixed to the bracket of the support plate 17. 17a
a support rod 22 that slides within an opening 21 opened in;
Contrary to this rod 22, a support rod 24 is fixed to the support plate 179 side with screws 23 and slides within the hole 16b on the support plate 16 side, and the rod 24 has a cam follower 25.
The arm 26 with the support plate 16 attached to the tip
An arm 28 to which a cam follower 27 is attached 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 27 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 moves the cam follower 25, the arm 26, the two-rod support plate 17, the sorting shelf plate 19, and the width. The regulating member 15 is moved integrally, and the cam surface of one cam 31 controls the follower 27 and the arm 2.
8, the rod 22, the support plate 16, the sorting shelf board 18, and the width regulating member 14 are moved together. During this movement, the width regulating member 14
and 15 are necessarily opposite directions, that is, when the member 14 moves in the direction of reducing the passage width (to the left in FIG. 2), the member 15
is also moved in the direction of reducing the passage width (rightward in Figure 2), and member 1
When the member 4 moves in the passage widening direction (the direction in FIG. 2), the member 15 is also moved in the passage width expanding direction (to the left in FIG. 2), and the amount of movement of each member 14 and 15 is made to be approximately equal. The shapes of the cams 31 and 32 are determined. Note that width regulating member 1
4 and 15 in the width direction, the bottom plate portions 18a and 18b must always exist in a bridging state on the lower surfaces of the width regulating members 14 and 15 at the starting and ending portions 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, there are bottom plate portions 18a, 1 except for the sorting shelf board 19 portion.
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 rotating a knob 34 provided at the other end of the camshaft 33 to the right in FIG. Although it has been done,
This rotation by the pick member 34 is used when manually expanding the passage width to remove jammed coins, and when changing the denomination, the passage width is automatically rotated by the motor M, so this A pin 35 is implanted in the member 34, and this pin 35 is connected to the drive motor M side.

That is, the pin 35 is inserted into the notch 37a of the rotary connecting cam 37 fixed to the tip of the motor shaft 36, the pin 38 is also protruded from the cam 37 side, one end is engaged with the pin 38, and the other is inserted. A spring 39 is provided whose end is attached to the pin 35 and wound around the camshaft 33, so that the pin 35 is always in contact with the engaging edge 37b at one end within the notch 37a, and the cam 37 is transmitted to the camshaft 33 side.

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 pin 35 is pushed by the engaging edge 37a of the rotary connection cam 37, and the cam shaft 33 is rotated together with the motor shaft 36 to change the passage width.

In addition, when a coin jam occurs during coin processing, the width of the passage can be expanded using the motor M to remove the jammed coins.In that case, operate the jammed coin removal button to reverse the motor M and rotate the motor shaft 36 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 a jammed coin, the reason why the motor 36 is reversed is that it is necessary to quickly return the passage width to the width corresponding to the denomination coin being processed after removing the jammed coin, and the return rotation of the shaft 36 by clockwise rotation is quick. This is to return it to its original position. When the left rotation connecting cam 37 of the motor shaft 36 is rotated to the left, the engaging edge 37b thereof is rotated in a direction away from the pin 35, but the pin 35 and the engaging edge 37b are kept in contact by the spring 39. The pin 35 is rotationally moved, the operating member 34 is also rotated to the left, and as a result, the camshaft 33 is also rotated to the left, thereby expanding the passage width, and then returning to the original position by rotating the motor shaft 36 to the right. At the time of return, the rotary connecting cam 37 is also rotated clockwise, the engagement edge 37b pushes the pin 35, the cam shaft 33 is rotated clockwise, and the cams 31 and 32 are moved to the passage width corresponding to the diameter of the denomination coin being processed. Bring it back. 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 knob member 34 is rotated counterclockwise, the pin 35 controls the rotating connecting cam 37. Difficult to rotate. 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 is only on the camshaft 33 side. Note that when the gripping member 34 is rotated 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 is stopped at the initial position. The rotating connecting cam 37 is also in a stopped state, the pin 35 is separated from the engagement edge 37b, and the cams 31, 32 are moved within the movable range of the pin 35 within the notch 37a of the cam 37.
The passage width is expanded. When you release your hand from the picking member 34, the spring 39 rotates the camshaft 33 of the picking member 3 to the left.
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 clockwise in FIG.
To determine the rotational position of the cams 31 and 32 when changing the denomination in which the cam 3 is rotated clockwise, there are 1 yen, 5 yen, and 10 yen rotation positions on the motor shaft 36.
From a positioning device P having five positioning cams 40, 41, 42, 43, 44 fitted for 0 yen, 10 yen, and 5Cf3, and switches SWl to SW5 arranged corresponding to the cams. is determined by transmitting a signal to said motor M.

In other words, each cam 31, 32 has one
Passage width determining surfaces for yen, 5 yen, IOFIJl5 old, and 10 old coins are located approximately symmetrically to the camshaft 33, and the cam followers 27 and 25 are also located approximately symmetrically to the camshaft 33. The cams are pressed against the passage width determining surfaces of the cams 31 and 32 at symmetrical positions, and the motor is driven to rotate clockwise so that the passage width corresponds to each coin.

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 12, and adjusts the height of the guide 45 depending on the type of coin. The aim is to ensure that only coins enter the hardening 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 11, and 47 is a support frame that is moved integrally with the support plate 16 and faces the downstream area of the coin passage 13. It is a star wheel that is forcibly rotated by the coin itself, which is transported by a coin conveying belt that is located at the upper part of the center in the width direction of the passage 13 and extends from the passage start end to the passage end. It is designed to count the number of sheets. In particular, the cam 31 fixed to the camshaft 33
, 32, the width regulating members 14, 15 are moved to predetermined positions on the cam surfaces of the cams 31, 32 according to the diameter of the denomination coins to be processed, as shown in FIG. Passage width determining surface portions 48a1, 4 consisting of concentric circular arc surfaces for positioning
8a2, 48a3, 48a4, 48ton and 48b1,
48b2, 48b3, 48b4, 48kg are formed, and 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 each has a passage for one yen coin. Used as the width determining surface.

Similarly 48a2 and 481), 48b3 and 48b3, 4
8a4 and 48b4, 48a5 and 48b5 are provided at symmetrical positions with respect to the camshaft 33, and are respectively for 5 yen coin and 10Cf.
This is the passage width determining surface for 3 coins, 1Cf3 coins, and 5 old coins. The order of each denomination coin diameter from small to large is:
The order is 1 yen, 50 yen, 5 yen, 100 yen, and 1 throat.
The power of cam 31 and cam 32! - The radius from the shaft 33 to the passage width determining surface is 48a4, 48a3. 48a2, 48
a5, 48a1 and 48b4, 48b3, 48Y)2
, 48kg, and 48b1.

The cam 31 also has a relief cam surface 48a6 having a diameter smaller than any of the passage width determining surfaces 48a3 to 48a3.
It is formed on the cam surface reaching 8a4. Further, on the cam surface of the circumferential surface of the cam 32, there are provided adjacent passage width determining surface portions between 48b1 and 48b2, between 48b2 and 48b3, between 48b3 and 48b4, between 48b4 and 48kg, and between 48b5 and 48b1. A concave portion 49 is formed in which the concentric cam surface has a radius smaller than the radius of all the passage width setting surfaces 48b1 to 48b5. Each concave portion 49 of this cam 32 is used to expand the width of the coin/coin passage, and if a coin is clogged in the coin passage 13, that is, a coin is clogged between the sorting shelves 18 and 19, or the width is restricted. In the case of a coin jamming between the members 14 and 15, the motor shaft 36 of the motor M that rotates the picking member 34 clockwise is rotated by a predetermined amount.
By rotating the cam 31 to the left and then returning to the right, the cam 31
, 32 are rotated to the right or left by a predetermined amount, thereby enlarging the passage width and returning it to its 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,
By clockwise rotation of the cam 32, the passage width determining surfaces 48b4 and 48
It falls into the recess 49 between b5, and moves the cam follower 25, arm 26, rod 2 support plate 17, sorting shelf board 9, and width regulating member 15 in the direction of widening the passage width on the left side of FIG. 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.
Even when the pin 35 is depressed, it remains in the middle part within 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 48Y) 3 changes when the cam 31 is rotated clockwise by the predetermined amount described above together with the cam 32. Even when the follower 25 falls, the cam follower 27 is still in pressure contact with the passage width determining surface portion 48b4, 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 the hand is released from the gripping member 34, the gripping member 34 and the camshaft 33 are returned to the counterclockwise rotation due to the spring force of the spring 39, and the pin 35 comes into contact with the engagement edge 37b of the rotating connecting cam 37 which is stopped.
The camshaft 33 is stopped from rotating, the passage width regulating member 15 returns to its original position, and forms the passage width before the passage width is expanded between the camshaft 33 and the stopped width regulating member. As a supplement, coin passage 13
In the case of a machine in which coins are jammed at the upper surface of the path starting end bottom plate portion 18a or the path end bottom plate portion 18b, the jammed coins may be manually scraped into the sorting groove 4A in the path width expanded state. Alternatively, a coin conveying belt mechanism (not shown), which extends over the center upper surface of the coin passage 13 in the width direction from the beginning to the end of the passage, may be rotated forward and backward when the passage width is expanded and removed to the sorting groove 4A. good. Further, when removing a jammed coin by the motor M, the motor shaft 36 is first rotated to the left by a predetermined angle, and the engaging edge 37b of the rotary connecting cam 37 is aligned with the pin 3.
It is moved in the direction away from 5.

However, due to the spring force of the spring 39, the pin 35
The camshaft 33 and the cams 31 and 32 are also rotated to the left as a result of the rotational movement while maintaining the engagement state with the camshaft 33 and the cams 31 and 32. that time,
The cam follower 25, which was in pressure contact with the passage width determining surface 48b4 of the cam 32, falls into the recess 49 between the passage width determining surface 48b1 and the passage width determining surface 48b3, and the sorting shelf 19 and the width regulating member 15 close to the passage. Moved in the direction of width expansion. On the other hand, the cam follower 27, which was in pressure contact with the passage width determining surface 48b4 of the cam 31, falls onto the relief cam surface 48a6 as the cam 31 is rotated counterclockwise by a predetermined amount together with the cam 32, and the cam follower 27 and the arm 28, the support plate 16, the rod 22, the sorting shelf board 18, and the width regulating member 14 are also moved in the direction of widening the passage width. As a result, in this case, both sides of the passage 13 in the width direction are expanded, and the jammed coins are removed from the sorting groove 4A. Thereafter, as the motor M returns to the right rotation of the motor shaft 36, the engagement edge 37b of the rotary connection cam 37 engages the pin 35.
is pushed, the cam shaft 33 and the cams 31, 32 are also rotated clockwise, and the passage width determining surface portions 48a4, 48b4 of the cams 31, 32 are rotated clockwise.
The motor M1 motor shaft 26 and the camshaft 33 are stopped with the cam followers 27 and 25 in pressure contact with the passage width regulating member 1.
4 and 15 also return to their original positions and stop. When changing the denomination, the motor shaft 36 of the motor M1 rotates clockwise, and the engaging edge 37b of the rotary connecting cam 37 pushes the pin 35 to rotate the cam shaft 33 clockwise, thereby determining the passage width of the cam 32. Surface portion 48b
Cam follower 2 that was pressed against any one of 1 to 48b5
5 necessarily falls into the adjacent recess 49 on the left side with respect to the clockwise rotation direction in FIGS. At the time when the cam follower 25 falls into the recess 49, the cam follower 27 that was in pressure contact with any one of the passage widths 48a5 and 48a5 maintains the state of pressure contact with the previous passage width determining surface, or is in a small diameter passage. The width regulating member 14 is in a depressed state toward the width determining surface portion, and the width regulating member 15 moves in the direction of expanding the passage width. As a result, coins that are stuck between the sorting shelves 18 and 19 and have not been noticed are removed into the sorting groove 4A.

After this passage width is expanded, the passage width is changed to that of another denomination of coins, so even if the passage width is changed to reduce the passage width, the passage width will not get stuck between the sorting shelves 18 and 19. This will not cause any unnoticed deformation or damage to the coin. In this way, when removing jammed coins by manual operation using the picking member 34, when removing jammed coins by rotating the motor M, 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, In the case of , the cam follower 25 falls from the passage width determining surface portion that was in pressure contact to the adjacent recess 49,
The width regulating member 15 and the sorting shelf board 19 are thereby moved in the direction of expanding the passage width, and at this time the width regulating member 14 is either in a constant position or in a state of movement in the direction of expanding the passage width,
As a result, the passage width will definitely be expanded.

In this embodiment, an example of the passage width adjustment cam of the present invention is shown as the passage width adjustment cam 32, an example of the contact part is the force follower 25, and an example of the cam shaft of the passage width adjustment cam is shown as the cam shaft 33. There is. The cam follower 25 serving as a contact portion may be fixed to the width regulating member 15, but in this example, it is attached via an arm 26 to a rod 24 that moves together with the member 15. In this embodiment, the drive shaft of the present invention is the motor shaft 36, the connecting member is the rotating connecting cam 37, the engaging edge of the connecting member is the engaging edge 37b1, the engaged member is the pin 35, and the spring is the spring 3.
9. The operating member is shown as operating 34.

Next, the operation of this embodiment will be explained.

For example, when a 1 yen coin is placed on the rotating disk 12 and counted, a 1 yen denomination setting button in a group of 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 the selection of the 1 yen coin denomination is set to a passage width for a 50FI1J coin, which has a larger diameter than the 1 yen coin, the cam follower 25 before the selection of the denomination is the 50F of the cam 32. The cam follower 27 is in pressure contact with the passage width determining surface 481) of the cam 31 for 50FI]. When the aforementioned motor M is rotated clockwise from this state, the cam follower 2
5 falls into the concave portion 49 of the square cam 32, rides on the passage width determining surface portion 48b1 for 1 yen, and the cam follower 2
7, after the cam follower 25 continues to be in pressure contact with the passage width determining surface portion 48a5 for 5Cf3, the cam follower 25 contacts the passage width determining surface portion 48b1.
At the time of getting on the 1 yen passage width determining surface part 48a1
When both cam followers 25 and 27 have climbed onto the passage width determining surfaces 48b1 and 48a1, SWl is pressed to stop the motor M, and the motor shaft 36, the connecting cam 37,
The rotation of the pin 35, the gripping member 34, 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 determine the passage width and sorting groove width from the old 5 coins to the 1 yen coins. In this manner, during the denomination change movement, as described above, the cam follower 25 necessarily falls from the path width determining surface before the change into the adjacent recess first, so that the width regulating member 15 and the sorting shelf board 19 is moved in the direction of passage width expansion, and at this time, the cam follower 27 remains in pressure contact with the passage width determining surface portion before the change, or is depressed to a passage width determining surface portion with a smaller diameter, or a relief 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 aisle width, and as a result, the aisle width is first expanded from the aisle width before the change, and then , the passage width has been changed to the width for coins of the desired denomination, and therefore the coins that were stuck in the sorting groove 4A of the passage 13 before the change are reliably ejected into the sorting groove 4A when the passage width is expanded, and the coins are sorted. It is discharged to the lower part of the machine and stored by a chute (not shown) facing the groove 4A. In particular, the passage width adjusting cams 31 and 32
are the passage width determining surfaces 48a1 to 48a5 and 4 concentrically.
8b1 to 48 kg, the cam rotates smoothly without requiring any force to rotate the cam.

When the above settings are completed, press the start button and rotate the rotating disk 1.
2 is 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) into 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 a coin gets stuck in this passage width, the cam follower 25 can be moved into the recess 4 by manually rotating the picking member 34 clockwise by the operator.
9, and the width of the passage 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 7 is released from the gripping member 34, the gripping member 34 and the camshaft 33 return to their original positions by rotating counterclockwise due to the force of the spring 39. If this removal operation is to be performed automatically, the operator presses a switch (not shown) to reverse the motor M, causing the motor shaft 36 to rotate to the left and the spring 39 to rotate the pin 35 so that it follows the rotation connecting cam 37. Rotation causes the same effect as described above.

Further, by clockwise rotation of the motor M and the motor shaft 36, the cam shaft 33 and the cams 31, 32 are also returned to their original positions, and denomination coin processing can be resumed. 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. , a concentric circular arc surface with a diameter that matches the passage width for each denomination, and a recess 49 that is smaller in distance from the camshaft center than the adjacent passage width determining surface part may be formed between each passage width determining surface part. .

In addition, when the passage width regulating member 15 and the sorting shelf board 19 are fixed, the cam 32 is eliminated and the cam 31 is attached to the passage width determining surface section 4.
The diameter from the cam shaft 33 of 8a1 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, 48
A concave portion such as a6) may be provided in each case.

As described above, according to the present invention, when changing the coin denomination to be processed, the passage width can be adjusted by automatically operating the camshaft using the drive shaft driven by the motor, making it easy to change the passage width. This makes it easy to operate, and when changing the passage width, the passage width is enlarged and then changed to the desired passage width, making it easy to notice the jammed coins when they are found between the sorting grooves. Even if the width of the passage is changed without changing the passage width, the coins that are stuck between the sorting grooves will be reliably removed from the sorting grooves, deforming the jammed coins and making them unusable.
If the cam or camshaft has never been damaged, and if a large number of coins become jammed during processing, the camshaft can be rotated manually even if the driveshaft is too heavy to rotate manually. This has excellent effects such as expanding the passage width and reliably removing jammed coins.
