Next, the operation of the above embodiment will be described.

First, when the coin wrapping machine is shipped, normally, the ROM storing the coin information such as the denomination, diameter, thickness, and the number of packaging units of the distribution destination (exporting destination) coin is stored in the coin information input unit 135. The coin information is stored in the storage unit 137 by being set in the coin packaging machine through. Then, if it is desired to partially change the coin information at the shipping destination or to add one denomination, it can be input by operating the key unit 115. Also, all coin information may be input by operating the key unit 115.

Next, the operation when the coin wrapping machine is actually used will be described. By operating the up / down buttons 130 and 131 as the denomination designating unit 134, the operation is stored in the storage unit 137. The denominations of the coins to be processed are sequentially displayed on the denomination display 124, and the denominations of the processed coins are designated by stopping the coins to be processed in the displayed state. At this time, the number of packaging units of the denomination coin is also displayed on the packaging number display 125 at the same time.

Based on the above denomination designation, the control unit 132 reads the diameter and thickness of the designated denomination from the storage unit 137, and adjusts the passage width L of the coin passage 6 to be slightly larger than the diameter. The required number of pulses of the pulse motor M _1, the amount of rotation of the DC motor M ₂ required to adjust the passage height of the coin passage 6 to a height suitable for its thickness, and the inner diameter of the coin accumulating portion 7 are set as follows. The number of pulses of the pulse motor M ₃ required to adjust the diameter slightly larger than the diameter is calculated, the fixed position return command is issued to each adjusting unit to return each adjusting unit to the fixed position, and then the pulse is calculated. Each control unit is automatically adjusted by rotating the motor of each control unit by the number and the amount of rotation.

The operation of each control unit will be described below.

Regarding the coin passage width adjusting unit 141, the stepless cam 25 rotates in response to the rotation of the pulse motor M ₁ and rotates a predetermined angle in the clockwise direction from the fixed position shown in FIG. 2, and moves by pushing the cam follower 23. The passage member 17 is advanced to the right in FIG. 2 by the guide action of the guide rollers 22 and 22 and the elongated holes 21 and 21, and the passage member 17 is stopped at an interval with respect to the fixed passage member 16. As a result, the passage width is adjusted to correspond to the set coin diameter. Therefore, since the cam 25 has a circumferential surface whose radius changes steplessly, it is possible to adjust the passage width with one rotation pulse of the pulse motor M ₁ as one pitch, which allows substantially stepless adjustment. Coins of any outer diameter can be accommodated as long as the outer diameter is within the range of the passage width and the minimum passage width.

As the movable passage member 17 moves to the right, the pin 28 serving as a fulcrum of the auxiliary passage member 27 also moves, and the passage surface 27 a gradually moves toward the edge portion of the movable passage member 17 accordingly. The angle with respect to 17b becomes smaller and approaches a straight line. Further, by the movement of the movable passage member 17, the outlet bottom plate 18 is rotationally displaced about the shaft 31 through the elongated hole 34 and the pin 32 in the time direction, and the auxiliary passage member 35 and the sensors S ₂ and S ₃ are used for the auxiliary movement. The position is parallel to the passage surface 27a of the passage member 27. Therefore, as the coin passage width becomes narrower, the passages formed by the auxiliary passage members 27 and 35 are linearly displaced, and the ends thereof move forward to approach the coin accumulating portion 7 to the coin accumulating portion 7 regardless of the coin diameter. The entry status of will not change.

On the other hand, in the coin passage height adjusting unit 142, the stepless cam 67 is rotated by a predetermined amount by the rotation of the DC motor M ₂ , and the cam follower 69 is pushed down, whereby the movable frame 48 is attached with the spring 62. It descends against the force, and the height at which the lower surface of the conveyor belt 43 is positioned is adjusted to a position where it can be conveyed by being pressed into contact with the upper surface of the coin with the denomination set. Along with this, the thickness regulating member 41 is also adjusted to a height position where only one coin can pass along the lower surface.

Regarding the collecting portion inner diameter adjusting portion 143, the stepless cam 92 rotates clockwise from the position of FIG. 8 by an angle corresponding to the number of pulses in response to the rotation of the pulse motor M ₃ . As a result, the cam follower 91 is pushed by the cam surface and gradually moves away from the center of the cam 92, and the first link 83 rotates clockwise around the shaft 82a, and the block 71 connected to one end of the first link 83 is rotated. Move to the left in the figure. Along with this movement, the second link 86 rotates counterclockwise around the shaft 84 through the third link 88, and moves the block 72 on the other side to the right. As a result, the distance between the facing surfaces of the left and right belts 77, 78 is increased, the distance is set to match the outer diameter of the coin of which the denomination is set, and the links 83, 86 are rotated to block 71, 72. 8 moves slightly downward in FIG. 8, that is, in the direction away from the end of the coin passage 6, and as the diameter of the coin increases, it moves away from the coin passage 6 and takes a position suitable for receiving coins. Further, the rotation of the first link 83 causes the lever 94 to rotate clockwise about the shaft 84 via the link 95, and the closing member 93 at the tip of the lever 94 retreats to move the gap between the belts 77, 78. It is placed in a position commensurate with the increase. As a result, the inner diameter of the coin accumulating space formed by the belts 77 and 78, the closing member 93, the guides 99 and 100, etc. is adjusted steplessly to a size that matches the outer diameter of the denomination-set coins.

Regarding the drive system of the coin stacking unit 7, the arms 105 and 106 are connected to the member 112 by the shafts 109 and 110 as the belts 77 and 78 move in the left-right direction. Move in a direction in which the belts 77 and 78 expand to each other and follow the expansion between the belts 77 and 78, but the gears 107 and 108 are always in mesh with each other, so that the driving force of the motor M ₄ is the gear 113. , 103, 107, 108, 104 are transmitted to the pulleys 74, 76 of the belts 77, 78 regardless of changes in the distance between the left and right belts 77, 78.

By the above operation, all of the passage width and passage height of the coin passage 6 and the inner diameter of the coin accumulating portion 7 are set to values suitable for the coin diameter and coin thickness of the denomination to be processed.

Next, the operation from the delivery of coins to the collection will be described.

When the denomination is set and the start button 128 is pressed, the rotary disc 4 is driven and coins inserted from the hopper 3 are supplied onto the rotary disc 5. At this time, the existence state of the coins on the rotating disk 5 is monitored by the level sensor S ₄ , and the supply state is controlled. The rotation of the rotating disk 5 causes the coins on the rotating disk 5 to be removed from the periphery of the coin thickness regulating member 41 under the lower surface. The coins in the upper layer in the two-ply state are removed to form a single layer state, flow into the coin passage 6, are pressed by the lower surface of the conveyor belt 43 on the inlet bottom plate 15, and the coins are rotated by the rotation of the conveyor belt 43. The fixed passage member 16 of the passage 6 and the edge portions 16b, 17b of the movable passage member 17 are conveyed in a state of straddling them. When a small-diameter coin smaller than the space between the edge portions enters, it is dropped and removed from the exclusion hole 19 between the edge portions.

The coins reaching the end of the coin passage 6 are counted by the count sensor S ₂ , the passage is confirmed by the sensor S ₃ , and the coins are guided by the rollers 40, 40 ...

In this coin stacking unit 7, the supporting units 79 and 80 of the left and right belts 77 and 78 are located near the upper ends, and the coins are laid across these supporting units 79 and 80, and one coin is mounted. After that, the pulse motor M ₄ rotates a predetermined pulse corresponding to the thickness of the coin based on the signal from the sensor S ₃ to rotate the belts 77 and 78, and the supporting portions 79 and 80 correspond to the thickness of one coin. Just descend.

When the coins of the packaging unit number are counted by the count sensor S _{2 in} this way, the signal is energized to the operation solenoid (not shown) of the stopper 36 so that the stopper 36 advances into the coin passage 6 and coins after that are inserted. Stop it.

The predetermined number of accumulated coins that have entered the coin accumulating section 7 are transferred to the supporting means (not shown) by the supporting sections 79 and 80 of the belts 77 and 78 moving outward from the lower ends, and then transferred to the packaging section 10. The coins are guided and wrapped by the wrapping paper 8, and the wrapped coins are discharged from the outlet 11.

Although the coin passage width adjusting means, passage height adjusting means, coin accumulating portion inner diameter adjusting means and the like in the illustrated embodiment have been shown as the most preferable embodiments, the technical concept of the present invention will be described with respect to the concrete constitution of each portion. The design change is optional within the range not deviating from.

【The invention's effect】

 As described above, according to the present invention, even a coin passage width adjusting device that can be adapted to coins of any diameter by the stepless cam can be used by setting the denomination of coins to be processed. Since the width is automatically set to a value that matches the diameter of the set denomination coin, it is extremely easy to change the denomination of the processed coin, and if the coin remains in the passage. However, it can be automatically excluded when setting the denomination.
