Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a plurality of through-holes having a diameter slightly larger than that of the disc-shaped bodies at the bottom of a hopper that can accommodate a large number of disc-shaped bodies. Alternatively, a rotary body having notches formed at predetermined intervals in the circumferential direction is attached, and a plurality of support parts that contact a part of the back surface of the rotary body to rotationally support the rotary body are attached to the bottom of the hopper. A plurality of discharge ports are formed on the bottom of the hopper to discharge foreign matter mixed in the disk-shaped body group to the outside. The present invention relates to a disk-shaped object feeding device that is provided with a guide section that transfers and guides the disk-shaped object inside the through hole or notch, which is pressed and moved as the body rotates, to the outside of the rotating body.

[Conventional technology]

In this type of disk-shaped body feeding device, a plurality of support parts are attached to a resin bottom plate constituting the bottom of the hopper, and the support part contacts a part of the back surface of the rotary body to rotationally support the rotary body. was integrally formed so as to protrude upward from the upper surface of the bottom plate.

[The problem that the idea aims to solve]

By the way, by rotatably supporting the rotary body with a plurality of support parts, for example, compared to the case where the rotary body is rotatably supported with its entire back surface in contact with each other, it is possible to reduce the amount of damage caused by the rotation of the rotor. Although it is possible to suppress the frictional heat generated by the sliding contact as much as possible to avoid burning of the contact surfaces, it is necessary to distribute and support the entire load that acts when the rotating body rotates using multiple small-area supporting parts. As a result, the support part wears out prematurely, and it is desirable to replace the support part.

However, as in the past, the support part is integrally formed with the bottom plate, so in order to replace the support part, the bottom plate itself must be replaced, which not only increases costs, but also causes damage to the bottom plate. Various parts such as the electric motor for driving the rotating body that are attached to the bottom plate must be removed one by one and replaced with a new bottom plate, making the replacement work time-consuming and troublesome.

An object of the present invention is to reduce costs and facilitate replacement work.

[Means to solve the problem]

The device for feeding out a disc-shaped body according to the present invention is configured to attach an auxiliary support part to some of the discharge ports for rotationally supporting the rotary body by contacting a part of the back surface of the rotary body. It is characterized by being configured in the mounting hole, and its functions and effects are as follows.

[Effect]

When the support parts become worn out and need to be replaced, auxiliary support parts are attached to some of the discharge ports, and the rotating body is rotatably supported by the auxiliary support parts.

[Effect of idea]

Therefore, when the support part becomes worn out and needs to be replaced, it is only necessary to attach the auxiliary support part to a part of the discharge port, which makes it easier to replace the bottom plate itself on which the support part is formed, as in the case of conventional methods. In comparison, costs can be reduced and replacement work can be carried out easily and quickly.

Incidentally, by attaching the auxiliary support portion to only some of the discharge ports, it is possible to discharge foreign matter from the discharge ports without any trouble as in the conventional method.

〔Example〕

FIGS. 7 and 8 show a device for feeding out medals M, which is an example of a disc-shaped body, in which a bottom plate 1A of a hopper 1 that opens upward is inclined at approximately 30 degrees with respect to a horizontal plane. A rotating body 3 driven by an electric motor 2 is attached to the upper surface of the bottom plate 1A, and a plurality of through holes 3a having a diameter slightly larger than the medal M are provided in the rotating body 3 in a predetermined circumferential direction. They are formed at intervals.

The hopper 1 is comprised of the resin bottom plate 1A screwed to the base plate 4, and a hopper case 1a held in place by the bottom plate 1A. Note that 29 shown in FIG. 8 is a support stand for supporting the feeding device.

As shown in FIG. 1, the bottom plate 1A has a circular recess 3b for rotatably supporting the rotating body 3.
and a medal delivery port 5 formed on one outer side thereof. A C-shaped rotating body guide part 6 concentric with the circular recess 3b is formed protrudingly within the circular recess 3b, and a metal piece 7 having an upper surface at the same height as the guide part 6 is provided in the notch of the guide part 6. is installed. The metal piece 7 is transferred by the rotary body 3 to a portion that is slightly displaced inward in the rotational radius direction from an extension line around the rotation axis X of the rotary body 3 that passes through the center of the through hole 3a of the rotary body 3. The medal M is brought into contact with the medal M that has been passed through the medal delivery port 5.
A medal guiding protrusion 8 is provided as a guide portion for guiding movement toward the medal.

The protrusion 8 is configured to be able to move forward and backward into a position where it protrudes above the metal piece 7 and a position where it is retracted into the inside of the metal piece 7, and is supported by a spring (not shown).
The metal piece 7 is urged to move to a position where it protrudes above the metal piece 7. Therefore, when the medal M transferred by the rotary body 3 is caught between the rotary body 3 and the protrusion 8, as the rotary body 3 rotates, the medal M pushes the protrusion 8 downward. , so that the jamming can be eliminated by getting over it.

A guide piece 9 that contacts and guides the medal M at the upper side of the medal delivery port 5 in the medal rotation transfer direction.
is fastened with screws, and a counter member 10 is swingably attached to the lower side of the medal M in the medal rotation transfer direction for contacting and counting the medals M sent out from the rotating body 3. It is being As shown in FIG. 6, this counter member 10 includes a counter roller 11 that comes into contact with the medals M sent out from the rotary body 3, and a counter roller 11 that is attached in an idling state, and the bottom plate 1A. a counter arm 12 that is swingable around a first axis Y in a direction perpendicular to the counter arm 12; It is composed of a first spring 13 and a first spring 13.

A medal M fed out by the rotary body 3 is placed near the counter roller 11 on the inner side in the rotational radial direction and on the lower side in the rotational direction.
A guide roller 14 is provided which contacts the medal M and guides the medal M toward the medal delivery port 5 side, and this guide roller 14 swings around a second axis Z parallel to the first axis Y. It is freely attached to a guide arm 15 attached to the lower surface of the base plate 4 in an idling state, and is urged to move toward the rotating body 3 by a second spring 16. The counter arm 12 is swingably attached to a protruding piece 17 attached to the lower surface of the guide arm 15, and the guide arm 15 swings away from the rotating body 3 when it comes into contact with the medal M. When the counter member 10 is moved, the counter member 10 is swung integrally with the guide arm 15.

A gate-shaped photoelectric sensor 18 is attached to the base plate 4 via a mounting member 19 for detecting passage of a counter portion 12a formed at the free end of the counter arm 12 when the counter arm 12 swings. This sensor 18
is composed of a light emitting part located on both sides of the movement path of the counter part 12a, and a light receiving part that receives light emitted from the light emitting part, and the medal M sent out from the rotating body 3 is placed on the counter. By contacting the roller 11 and passing between the light emitting part and the light receiving part, the counter part 12a blocks light from the light emitting part to the light receiving part, and it is determined that the medal M has been sent out to the medal sending port 5. Then, the medals M are counted.

On the back surface of the base 4, a stopper 20 that protrudes above the bottom plate 1A through an opening 1K formed in the bottom plate 1A and comes into contact with and prevents movement of the medal M toward the medal delivery port 5 side is swung through a bracket 21. It is mounted so that it can move freely. Also, the stopper 20
is swing-biased by a spring (not shown) to a protruding position protruding above the bottom plate 1A. In order to hold this stopper 20 in the direction of retiring it downward from above the bottom plate 1A, one end of a spring 13 that swings and biases the counter arm 12 is attached to the stopper 20. For example, if the spring 13 is broken, If the counter roller 11 stops at a position where it does not come into contact with the medals M to be sent out, the stopper 20 prevents the medals M from being sent out from the medal delivery port 5 without being counted. It is designed so that it can contact and prevent the sending out.
