Description

[Detailed Description of the Invention] The present invention includes a rotating disk that sends out coins by centrifugal force,
A coin passage extending outward from the periphery of the rotating disk to receive coins sent out from the rotating disk, align and transfer them, and remove small-diameter coins from the sorting groove by passing through a sorting groove provided in the middle of the transfer. and a pair of passage width constituent members which define a passage width and a sorting groove width in the coin passage, at least one of which is adjustable and movable in the passage width direction, and a passage width constituent member which is adjustable and movable or integrated with the member. A contact part provided on a moving member and a passage width for each denomination for moving and positioning the passage width component that can be adjusted and moved by contacting this contact part to a passage width position corresponding to the denomination coin diameter. In a coin handling machine comprising a passage width adjusting cam having a determining cam surface on its circumferential surface, and a coin floating prevention plate facing a predetermined height position in the coin passage and preventing the transferred coins from floating, The present invention relates to a residual coin detection device that detects whether or not there are residual coins.

In the above-mentioned coin processing machine, when the processing of coins of a given denomination is completed and processing of coins of other denominations is to proceed, the clear button is operated to eject the coins from the coin passage, and then the next processing is performed. Set the denomination you want.

However, the operator often forgets to operate the clear button, and as a result, coins before the denomination change remain in the coin passage. Furthermore, operating the clear button does not necessarily automatically remove coins from the coin passage, and coins may become jammed and remain in the coin passage. If the denomination to be processed next is changed with such residual coins present, the passage width adjustment cam will move the passage width component from the passage width determining cam surface of the denomination before the change to the next passage. It moves to the width determining cam surface and then to the passage width determining cam surface next to it, and is regulated by the changed passage width determining cam surface,
During the transition, if any of the passage width determining cam surfaces is a cam surface that moves the passage width constituent member in the passage width reduction direction, the remaining coins may be damaged, and various devices such as the passage width constituent member and the passage width adjustment cam may be damaged. This will damage the parts.

To solve these shortcomings, we thought of detecting coins remaining in the coin passage, but we went a step further and went beyond simple detection to easily detect coins remaining in the coin passage. If it is possible to eliminate the retention (in the case of a residual coin that is about to fall out of the sorting groove and gets caught and easily falls out of the sorting groove by applying a small amount of force), the residual coin will be removed when the residual coin is detected. I also thought about canceling it. In order to solve these problems, selection is necessary. We focused on the fact that a coin levitation prevention plate is provided at the top of the groove, and came up with the idea of using this coin levitation prevention plate to detect residual coins. The present invention has been made based on the above idea, and it is possible to fix the coin levitation prevention plate to the driven lever and move it downward from a predetermined height position for preventing transfer and coin levitation, and to set the denomination. an electric drive unit that rotates the camshaft of the passage width adjustment cam in response to a signal from the unit; and the electric drive unit rotates in conjunction with the passage width adjustment cam to position the coin floating prevention plate at a predetermined height position. The coin floating prevention plate is lowered during the time when the height regulating cam surface and the contact portion are in contact with the path width determining cam surface before changing the path width until they are in contact with the adjacent path width determining cam surface. a rotating cam with a descending cam surface, a drive lever that has an engaging portion that engages with the cam surface of the rotating cam and is activated to follow the cam surface when the rotating cam rotates, and a coin floating prevention plate. is a lever to which is fixed, and is moved by the operation of the drive lever, raising and lowering the coin floating prevention plate, and when the coin remaining in the coin passage prevents the coin floating prevention plate from lowering, its movement is A driven lever that is stopped, a pin that connects the driven lever and the driving lever so that the driving lever can be operated even if the driven lever stops moving, a spring provided between both levers, and a spring provided between the two levers, and A stopper for regulating the position of both levers against the bias, and a detection switch for detecting remaining coins in the coin passage by detecting stoppage of movement of the driven lever when the drive lever is in the operating state. It is characterized by a predetermined height position to prevent the coin from floating (in countries where there is a large difference in the thickness of coins of each denomination, a predetermined height position where the thickness is adjusted according to the denomination, In addition, in countries where the thickness of coins of each denomination is similar, this means that no adjustment is necessary and the coins are at a predetermined height position at a constant height.

) When changing denominations, the coin floating prevention plate located at This is resolved by the descent of the coin surfacing prevention plate, and if the residual state of the coin is not resolved, the coin prevents the coin from descending, thereby stopping the coin surfacing prevention plate and the driven lever, and the operating state of the drive lever. The purpose of the present invention is to detect the stoppage of movement of the driven lever at the time using a detection switch so that it is possible to know whether there are any remaining coins. Hereinafter, a case where an embodiment of the residual coin detection device according to the present invention is applied to a coin counting machine will be described.

A rotating disk 2 rotated by a drive motor (not shown) is provided on the machine base 1 of the coin counting machine A so as to be rotatable in the direction of the arrow in a horizontal plane, and outward from the periphery of the rotating disk 2. A coin passage 3 is extended.

A coin is inserted onto this rotating disk 2, but this coin C
is moved in the circumferential direction by the rotation of the rotating disk 2, and is moved along the guide edge 5 of the coin guide rail 4 attached near the periphery of the rotating disk 2 and communicating with the coin passage 3, It will be sent to 3. The hard passage 3 includes a coin guide plate 6 which swingably connects the coin guide rail 4 through a connecting piece 4'' and which guides the edge of the coin fed in, and a coin guide plate 6 which guides the other edge of the coin. A coin sorter is fixed to the other coin guide plate 6a and to the lower surface of each of the coin guide plates 6, 6a, and constitutes a removal port E as a sorting groove for removing coins having a smaller diameter than the coins of the denomination to be processed. It is composed of plates 7 and 7a.

The coin guide plate 6 and the coin sorting plate 7 are one of the passage width constituent members, and the coin guide plate 6a1 and the coin sorting plate 7a are the other passage width constituent members, and in this example, both are movable in the passage width direction. has been done.

On the downstream side of the coin passage 3, there is a star-shaped counting wheel 8 that engages with the edge of the coin that has passed through the coin passage 3 and rotates by a predetermined angle.
is provided. The coin guide plates 6, 6a are movable base plates 1 that can be adjusted and moved according to the diameter of the denomination coins to be processed.
0, 10a, and this movable base plate 10, 10
The above-mentioned coin sorting plates 7, 7a are also provided on a, and the movable base plates 10, 10a are provided with guide rods 11,
11a. A scraper is disposed above the coin passage 3 and presses into contact with the upper surface of the coin fed into the coin passage 3 along the coin guide rail 4 to forcibly move the coin and discharge it into the discharge port 12. A bell leash 13 is wound around a pair of pulleys 14, 14a.

The pulleys 14, 14a are supported by a support frame 15, and the shaft 16 of one pulley 14a is connected to a drive motor (not shown). The shaft 17 of the other pulley 14 is connected to the support frame 1
5 is rotatably supported. Further, it is located above the coin passageway 3, close to the scraping belt 13, and over almost the entire longitudinal direction of the coin passageway 3, to prevent coins from being forcibly moved by the scraping belt 13 from becoming loose. A coin floating prevention plate 18 is provided.

This coin floating prevention plate 18 (which also serves as a detection member for detecting the presence or absence of residual coins, which will be described later) prevents coins from floating in countries where there is not much difference in thickness between denominations of coins. The predetermined height position for the denomination may be constant, but in this example, the predetermined height position can be adjusted depending on the denomination,
The distance between the lower surface of the coin floating prevention plate 18 and the upper surface of the coin sorting plates 7, 7a can be adjusted in the vertical direction according to the thickness of the coins to be processed.

This adjustment is made by the mechanism shown in FIG. That is, this mechanism transmits the lift amount by the cam 37 via the first and second arms 25 and 29 to the support plate 19 that swings around the pin 20, and the coin fixed to the tip of the support plate 19. The anti-surfacing plate 18 is adjusted in the vertical direction with respect to the coin passage. More specifically, the coin floating prevention plate 18 is fixed to a support plate 19 provided below the support frame 15, and the support frame 15 and the support plate 19 are connected to pins provided on the base plate 2. It is supported so as to be swingable in the vertical direction with respect to the coin passage 3 with 20 as the center.

An adjustment screw 21 is screwed into the support frame 15 to adjust the distance between the support plate 19 and the support plate 19. The lower end of the support plate 19 is connected to the adjustment screw 21 by a hanging pin 22 fitted into the support plate 19. A compression spring 23 is inserted through the spring 21 to maintain contact with the lower end of the spring 21. One end on the opposite side of this support plate 19 is fixed to the upper surface of a bracket 24, and a first arm 25 is fixed to the lower part of this bracket 24. The first arm 25 has a hook-shaped tip, and is connected to the second arm 29 by a pin 27 at an intermediate point so as to overlap. An adjustment screw 30 is interposed between the knee portion 29a of the arm 29 and the arms 25, 29 are pulled by a tension spring 32, so that the arms 25, 29 can be bent in only one direction. ing. When this bending occurs (that is, when the coin floating prevention plate 18 presses the coin on the coin path), a detection switch 26 is installed on the abdomen of the first arm 25 to detect this state. It is set up.

Therefore, this switch 26 is pressed by the operating edge 28 of the second arm 29 when the bending occurs. On the other hand, a cam follower 33 is attached to the other end of the second arm 29, and the cam follower 33 engages with a cam 37 to be displaced in the vertical direction. This cam 37 is for lowering and adjusting the height of the coin floating prevention plate 18, and is fixed to the denomination selection shaft 36.
This shaft 36 is driven by a denomination selection drive motor 34 which is driven when changing the coin denomination to be processed.
35.

Further, as shown in FIG. 3, this cam 37 includes a concave cam surface 38a that positions the coin floating prevention plate 18 at a predetermined height position to prevent coins from floating up, and a protruding cam surface that lowers the coin floating prevention plate 18. 38b is formed, and the recessed cam surface 38a extends from the axial center of the cam 37 to the recessed cam surface 38a.
The distance to the bottom of each coin varies depending on the thickness of the coin being processed. A protruding cam surface 38b is formed between the recessed cam surfaces 38a, 38a, and the distance from the axial center of the cam 37 to the protruding force surface 38b is equal, and the coin floating prevention plate 18 is connected to the upper surface of the coin sorting plates 7, 7a. The dimensions are such that it can be lowered to the desired position. Furthermore, two passage width adjusting cams 39 and 40 are fixed to the denomination selection shaft 36 to adjust and control the width of the coin passage 3 according to the diameter of the coins to be processed. This is a well-known passage width adjusting cam, and although its shape is not shown in detail, it has a protrusion as a passage width determining cam surface part and a sorting groove that determines the passage width at equal intervals according to the coin denomination to be processed. A passage width adjusting cam (a cam with a similar shape to the cam 37, which corresponds to the protruding cam part 38a of the cam 37) in which recesses are alternately formed to enlarge the passage width when changing the denomination in order to eliminate remaining coins. is a protrusion as a passage width determining cam surface, and the entire cam surface of one protrusion is an arcuate cam surface with the same radius from the camshaft, and each radius of each protrusion, that is, each arcuate cam surface Each radius is a radius from the cam shaft that differs depending on the denomination coin diameter, and a cam with a recess corresponding to the recessed cam surface 38a is formed between the protrusions, or a cam with no recess A passage width adjusting cam is used that has concentric passage width determining cam surfaces whose radii from the shaft vary depending on the denomination coin diameter, and a connecting cam surface that smoothly connects each passage width determining cam surface.

Then, when changing the denomination, the passage width determining cam for the predetermined denomination is configured such that the coin floating prevention plate 18 is lowered for detection when the passage width is in the state before the change or in the state where the passage width is expanded due to the change. A recessed cam surface 38a of a predetermined denomination is located within the rotational angle region of the surface portion (in the case of a cam having a recessed portion for expanding the passage width, the passage width determining cam surface portion and the recessed portion on the succeeding side in the rotational direction).
The cam 37 is formed and positioned in a corresponding relationship such that the protruding cam surface 36b on the succeeding side in the rotational direction exists. One of the passage width adjusting cams 39 is engaged with a cam follower 41, on which a counting device (not shown) including a coin guide plate 6, a coin sorting plate 7, and a counting wheel 8 is mounted. The other passage width adjusting cam 40 is rotatably supported by a bracket 42 fixed to the upper surface of the movable base plate 10, and the other passage width adjusting cam 40 is engaged with a cam follower 43. The sorting plate 7a is fixed to a slidable guide rod 11a which fixedly supports another movable base plate 10a on which the sorting plate 7a is placed.

Next, the effect will be explained.

By selectively pressing a denomination selection button corresponding to a plurality of denominations provided on a machine operation panel (not shown), the denomination selection drive motor 34 is driven, and the denomination selection shaft 36 is driven via gears 35, 35. rotates.

By rotating this denomination selection shaft 36, the height adjustment cam 37,
The passage width adjusting cams 39 and 40 are rotated. Due to the rotation of the passage width adjustment cams 39 and 40, the cam follower 41 and 43 come into contact with the passage width determining cam surface part in a predetermined rotational angle region, and then contact the adjacent recess (in the case of a passage width adjustment cam having a recess). Or, after contacting the connecting cam surface (in the case of a passage width adjustment cam without a recess), it contacts the next passage width determining cam surface, and if this passage width determining cam surface is the selected denomination cam surface, this passage The cams 39 and 40 stop rotating when the width determining cam surface is in contact with the cam followers 41 and 43, and if not, the cams 39 and 40 continue to rotate, and the passage width determining cam surface and the cam followers of the selected denomination are stopped. When 41 and 43 are in contact, the cams 39 and 40
rotation is stopped.

The passage width adjustment cam 39 moves the bracket 42 and the movable base plate 10 in the direction of passage width expansion through the cam follower 41 (in the case of a passage width adjustment cam with a recess), and then adjusts the movement or simply adjusts the movement (the recess (In the case of a passage width adjustment cam without a passage width adjustment cam), the coin guide plate 6 and the coin sorting plate 1 are positioned at positions according to the diameter of the coins to be processed, and the passage width adjustment cam 40 moves the bracket 44 and the coin selection plate 1 through the cam follower 43 The guide rod 11a is moved in the direction of expanding the passage width (in the case of a passage width adjustment cam with a recess) and then adjusted, or simply adjusted (in the case of a passage width adjustment cam without a recess) and fixed to the guide rod 11a. As the movable base plate 10a is moved, the coin guide plate 6a and the coin sorting plate 7a are positioned in accordance with the diameter of the coins to be processed.

By moving the movable base plates 10, 10a, the width of the coin passage 3 is adjusted according to the diameter of the coins to be processed.
On the other hand, the height adjustment cam 37 is also the passage width adjustment cam 39, 40.
The concave cam surface 3 before the denomination change is rotated at an equal angle in the same direction as the
The cam follower 33 that was in contact with the recessed cam surface 38
After climbing onto the protruding cam surface 38b from a, it engages with the next recessed cam surface 38a, and if this cam surface 38a is the recessed cam surface of the selected denomination, the recessed cam surface 38a and the cam follower 33
When the recessed cam surface 38a is not the cam surface 38a of the selected denomination, the rotation of the cam 37 is stopped when the cam surface 38a of the selected denomination is engaged with the cam follower 33.

The cam follower 33 rises from the concave cam surface 38a to the protruding cam surface 38b of the denomination before the cam 37 is changed.
When the cam followers 41 and 43 are in contact with the cam surface for determining the passage width of the denomination type before the change of the passage width adjustment cams 39 and 40, or when the passage width adjustment cams 39 and 40 have concave portions, the width of the passage width adjustment cams 39 and 40 are This is carried out when the cam followers 41 and 43 are recessed in the recessed portion adjacent to the cam surface portion that determines the passage width of the denomination. That is, this is performed during the time period from when the cam followers 41 and 43 are in contact with the passage width determining cam surface before changing the passage width to when they are in contact with the adjacent passage width determining cam surface. As a result, when the height adjusting cam 37 rotates, the cam follower 33 is moved and the second arm 29 having the cam follower 33 is also moved. In this case adjustment screw 30
, the first arm 25 moves integrally with the second arm 29 due to the connection with the tension spring 32 and the pin 27. Therefore, the support plate 19 fixed to the first arm 25 swings clockwise around the shaft 20, and the coin floating prevention plate 18 descends to the upper surface of the coin sorting plates 7, 7a for a short time. After stopping (the contact between the cam follower 33 and the protruding cam surface 38b), the coin levitation prevention plate 18 fixed to the support plate 19 swings counterclockwise around the pin 20 to prevent the coins from being processed. It is moved upward and placed at a position according to the thickness.
During this adjustment, the support frame 15 also swings around the shaft 30 integrally with the support plate 19 by the adjustment screw 21 and the compression spring 23, and this swing causes the coin scraping belt 13 to move the coins to be processed. It is located at a position according to the thickness of the Next, with the coin remaining on the coin passage 3,
When a denomination selection button (not shown) is selected and pressed to change to the next denomination to be processed, the denomination selection drive motor 34 is driven, and the height adjustment cam 37 and the denomination selection shaft 36 are driven. The passage width adjusting cams 39 and 40 rotate.

However, the protruding cam surface 38b of the height adjusting cam 37 in FIG.
When the cam follower 33 climbs up, that is, the cam followers 41 and 43 are still in contact with the passage width determining cam surface or the adjacent recess of the denomination before the change of the passage width adjustment cams 39 and 40, and the adjacent passage width When the coin guide plates 6, 6a and coin sorting plates 7, 7a are not moved after being rotated to the determined cam surface, or when they are moved in the direction of increasing the passage width due to the recess (in the case of a passage width adjustment cam with a recess) 2, the second arm 29 is pushed downward, and the coin floating prevention plate 18 comes into contact with the coin and does not swing around the shaft 20. Therefore, the first arm 25 and the second arm 29 are bent around the pin 27, and the adjustment screw 3 of the first arm 25 is bent against the elastic force of the tension spring 32.
0 and the knee portion 29a of the second arm 29 are separated. 7. Then, due to the center swing of the fulcrum 27 of the second arm 29, the operating edge 28 of the second arm 29 operates the switch 26 fixed to the first arm 25, and the coin remains on the coin passage 3. Detect that.

The detection signal from this switch 26 is transmitted to the denomination selection drive motor 34, and the motor 34 is stopped. In the case of residual coins that fall into the removal port E serving as a sorting groove and are easily dropped from the sorting groove by applying a slight force, the remaining coins will be removed when the coin floating prevention plate 18 is lowered for detection. The coins are pushed downward from the sorting groove by the coin flotation prevention plate 18 and removed from the sorting device, and the remaining coins are eliminated.
The coin floating prevention plate 18 continues to move in the same way as when there are no remaining coins, and the coin floating prevention plate 18 is positioned at a predetermined position according to the thickness of the denomination to be changed, and the passage width is also changed depending on the denomination to be changed. The passage width is set according to the coin diameter.

As described above, the present invention includes a rotating disk that sends out coins by centrifugal force, a rotating disk that extends outward from the periphery of this rotating disk to receive and align the coins that are sent out from the rotating disk, and a sorter that is provided on the way to the transfer. A coin passage through which small-diameter coins are removed from the sorting groove by passing through the groove, and a pair of passage widths in which a passage width and a sorting groove width are defined, and at least one of which is adjustable and movable in the passage width direction.
