This conventional type is ``a device that organizes and sends out coins one by one using a pin provided on a disk that rotates at an angle, and the center of rotation is the same as that of the disk.
A coin organizer characterized by a stirring needle that is pressed onto a disk by a spring and can rotate independently of the disk, and a protrusion on the disk that pushes up the stirring needle and applies an impact. It was a mechanism to prevent jamming in the dispensing device.

However, with the above-mentioned conventional device, if a coin gets caught pressing the stirring needle against the disk side, it becomes difficult for the stirring needle to ride on the protrusion.
On the contrary, there was a risk that the wedge action would cause a strong jamming state.

This invention aims to solve the above-mentioned conventional problems and provide a coin jamming prevention device for an inclined disc type coin processing machine that can prevent coins from being jammed by the coin stirring member. The feature is that a rotating disk is provided on the support frame with its axis of rotation inclined with respect to the horizontal plane, and an annular coin alignment groove is provided around the front surface of the rotating disk in which coins are lined up in a flat line. are recessed, and within the coin alignment groove, coin lifting protrusions having approximately the same thickness as the coin are arranged in a row at circumferential intervals slightly larger than the diameter of the coin, and the lower outer periphery of the front surface of the rotating disk A coin storage wall material surrounding the coin storage to form a coin storage is provided on the support frame, and a coin stirring rod-shaped body for stirring the coins in the coin storage is attached to the front surface of the rotating disk in a radial direction.

The front edge 11 of each coin lifting protrusion 10 on the side preceding the rotation direction A is located on the diameter line of the rotating disk 3, and the rear edge 12 on the opposite side is located on the tangential direction of the inner peripheral edge 5 of the coin alignment groove 4. They are formed with substantially matching diagonal edges. The thickness of the coin lifting protrusion 10 is approximately the same as the thickness of the coin C.

Reference numeral 13 denotes a coin guide disk with a dish-shaped cross section, which is fixed in a manner of engagement in a central recess 14 on the front surface of the rotary disk 3. The inner peripheral edge 5 is formed by extending the entire peripheral edge of the coin guide disk 13 into the coin alignment groove 4.

Reference numeral 15 denotes a rod-like body for stirring coins, which is a synthetic resin rod-like body with a square cross section and excellent wear resistance, and is configured in a straight line as shown in Figure 3, or in a cross-shaped or triangular shape as shown in Figures 8 and 9. is arranged in the radial direction at the center of the coin guide disk 13 on the front surface of the disk 3, and the bolt is inserted through the spring plate 16 with its center aligned with the center of the coin guide disk 13. 17. It is semi-fixed with a nut 18. The spring plate 16 has an elongated shape that straddles a dish-shaped recess formed by the coin guide disc 13 provided at the center of the rotating disc 3, and the coin stirring rod-shaped body 15 enters the dish-shaped recess. It is said to be the shape.

The spring plate 16 is formed in an elongated shape along the lower surface of the stirring rod 15 as shown in FIG. 6, and is bent into a dish shape when viewed from the side as shown in FIG. , its dish-shaped shape is set so as to have a certain amount of clearance between it and the coin guide disc 13 having a dish-shaped cross section.
Further, the spring plate 16 is provided with an engaging protrusion so as to engage with one side of the stirring rod-shaped body 15 and rotate together with the stirring rod-shaped body 15. As described above, when the stirring rod-shaped body 15 is semi-fixed via the spring plate 16, the spring plate 16 is elastically deformed as shown in FIG. It is attached so as to protrude radially outward and obliquely upward from both ends of the rod-shaped body 15, and is used as a stirring auxiliary member. In addition, the stirring rod-shaped body 15 and the rotating disk 3 are connected to each other due to the frictional force caused by the elastic deformation of the spring plate 16.
The spring plate 16 is configured to slip within a coin guide disk 13 that is integrated with a rotating disk 3 that rotates together with the coin guide disk 3 and generates a coin jamming as described later, thereby causing relative sliding.

Reference numeral 19 denotes a coin storage wall material made of a sheet metal, which has an arcuate cross-sectional shape along the inner periphery of the projecting peripheral wall 2 of the support frame 1, and has an outward tongue portion 20 on its lower edge in the circumferential direction. It is integrally extended. This coin storage wall material 19 has an outward tongue portion 20 that surrounds the outer periphery of the lower circumferential portion of the rotary disk 3, and the outer tongue portion 20 is attached to the support frame 1.
The side end portions 19a, 19 are disposed below the inward wall 21 projecting inside the lower projecting peripheral wall 2.
b is supported by the frame projecting peripheral wall 2 with a horizontal shaft 22 so as to be freely rotatable about the shaft. Further, on the outer surface of the coin storage wall material 19, a contact member 23 with an adjustment screw is attached so as to correspond to the upper side of the inward wall 21. This contact member 23 is in contact with the upper surface of the inward wall 21 under the tension of a spring member 24 stretched between the coin storage wall material 19 and the support frame 1, and due to this contact, the contact member 23 rotates with the outward tongue portion 20. Disc 3
The space between the coin alignment groove 4 and the coin alignment groove 4 is maintained constant, and the coins are set to accumulate in this area. That is, the coins C are stored in a coin reservoir surrounded by the coin storage wall material 19 at the lower front surface of the rotating disk 3, and some of these coins C are stored in the outward tongue portion 20, the coin alignment groove 4, and the protruding peripheral wall. The coins C enter the space surrounded by the coins 2 and 2, and the coins C that have entered the air enter the gaps between the coin lifting protrusions 10 arranged in the coin alignment groove 4 one by one, and as the rotating disk 3 rotates. It is twisted and lifted upwards.

A portion of the supporting frame projecting peripheral wall 2 corresponding to the upper position of the rotating disk 3 is cut out to provide a coin outlet 2.
5 is open and a delivery chute 26 is connected thereto. The delivery sheet 26 is provided with a counting switch 27 for counting the number of coins C delivered.

Further, a pressure roller 28 is supported by a pressure spring 29 near the coin outlet 25 so as to protrude into the coin alignment groove 4 from the outer periphery thereof, and the coin lifting protrusion 10 supports this pressure roller 28 . The coin C sent in front of the roller 2 has a part of its periphery
8, and this sliding force pressurizes the coins toward the inner circumferential edge 5 of the coin alignment groove 4. The mounting end of the pressure spring 29 is fixed to the support frame 1 with screws 30. Pressure roller 28
is attached to the tip of the pressure spring 29 with a roller holder 31.

Now, when a coin C is stored on the front surface of the rotating disk 3 and the motor 9 is driven, the rotating disk 3 rotates in the direction A, and the coin C is lifted up by the coin lifting protrusion 10 while the coin alignment groove The scraping protrusions 10, 10 in each of the scraping protrusions 4 are sequentially aligned and sent toward the outlet 25. The coin C that has moved forward of the delivery port 25 is once subjected to the pressure of the pressure roller 28, and at the same time as the pressure is released, it moves along the rear edge 12 of the scraping projection 10 into the delivery port 25. well released. At this time, the counting switch 27 counts. Subsequently, subsequent coins C are sequentially released in the same manner, and a predetermined number of coins are sent out. Further, at the same time as the coins are lifted and sent out, the coin stirring rod 15 rotates together with the rotary disk 3 to stir the coins C and facilitate the above-mentioned lifting and sending operations smoothly and reliably. .

However, the coins C stirred by the stirring rod 15 are sometimes forced into the space surrounded by the coin alignment groove 4, the outward tongue 20, and the projecting peripheral wall 2, as shown in FIG. A situation arises in which
That is, a jamming state occurs in which the group of coins C shown in FIG. 10 is pressed against the inner surface of the support frame projecting peripheral wall 2 by the rotational force of the stirring rod-shaped body 15 as shown in the figure.

When the coin C is bitten in this way, the stirring rod 15 receives resistance from the bitten coin C and stops while slipping inside the coin guide disk 13, but the rotating disk 3 stops inside the coin guide disk 13. Both plates 13 continue to rotate. Therefore, even if a coin is bitten, the coin feeding by the rotary disk 3 continues without interruption, and as shown in the figure, the coin is rotated together with the disk 3 to remove the bitten coin C. Coin lifting protrusion 10 moving towards
collides with the stuck coin C, and the stuck state is released, and as a result, the coin C, the outward lower part 20, the protruding peripheral wall 2, and the coin lifting protrusion 10 are deformed,
Damage can be prevented. After the coin is no longer jammed, the stirring rod 15 rotates together with the rotary disk 3 as before to perform the coin stirring function, as shown in the figure.

Further, both end portions 16a and 16b of the spring plate 16 protrude radially outward from both ends of the stirring rod-like body 15, and are provided so as to protrude diagonally upward in a direction different from the longitudinal direction of the stirring rod-like body 15. As shown in FIG. 2, it protrudes in the direction of the coin storage space, and has a great stirring effect on the coin C. Furthermore, even if the coin C gets caught between the ends 16a, 16b and the coin storage wall material 19, the ends 16a, 16b have elasticity, so the coin C will not get caught. It is easily elastically deformed in the direction of releasing the jamming, and the jamming is easily released. In addition, the vibration generated by the elasticity of each end 16a, 16b is also transmitted to the stirring rod 15, and the vibration prevents coins from being caught between the stirring rod 15 and the coin storage wall material 19. It also demonstrates. Furthermore, the stirring rod-like body 15 is attached to each end 16 of a spring plate 16 for semi-fixedly attaching it to the rotating disk 3.
This configuration uses a and 16b as stirring auxiliary members, which prevents an increase in the number of parts, has a simple configuration, and can be provided at low cost.

This invention has the above-mentioned structure, and the coin stirring rod 15 fixed in the radial direction at the center of the front surface of the inclined rotary disk 3 is rotated together with the rotary disk 3 during normal operation, and the coin stirring rod 15 is Since it is semi-fixed so that it stops when it is bitten, the coin can be stirred by the stirring rod 15 during normal times. Unlike a simple pin-shaped stirring member that protrudes from the top, it is set to be long in the radial direction of the disk 3 to increase the chances of contact with the coin C, so the stirring efficiency is higher than that of a pin-shaped stirring member. In addition, even if a coin gets caught, it can be quickly resolved, there is no need to interrupt coin feeding, and the lower edge of the coin and coin storage wall material 19 This has the advantage of preventing deformation or damage to the equipment.

Further, a spring plate 16 interposed when attaching the stirring rod-shaped body 15 to the rotating disk 3 in a semi-fixed manner
Since the ends 16a and 16b of the coin are also used as stirring auxiliary members, the stirring effect is great, and their elastic action also prevents coins from getting caught.
It has the advantage of being able to prevent an increase in the number of parts, has a simple configuration, and can be provided at low cost.
