Abstract

PURPOSE:To attain the transfer guide of a disk-shaped body besides a powdery particle by attaching spherical bodies able to freely turn and protruding into a hopper inside on the slidably contacting surface of a rotation body for a slidably contacting guide to be provided in the narrow part or the bent part of a passage inside the hopper. CONSTITUTION:Disk-shaped bodies M to be put in6to a first space 11 from the top of a hopper 1 are guided by inclined surfaces 13 and 14, reach a second space 12 through the bent part narrow in width on the way and arrive at the feeding port 1a of the bottom of the hopper 1. The disk-shaped bodies M are conveyed by an endless belt 2 obliquely rising up and arranged one by one in order to prevent overlapping on a chute 3. A rotation body 16 to slidably contact is installed with freely rotating on a shaft X on the side wall 1D of the bending part narrow in width on the boundary of the first and second spaces 11 and 12. Plural spherical bodies 17 able to freely turn are provided on the rotation body 16 in order to protrude into the inside of the hopper. Thus, even when many quantity of disk-shaped medals and coins besides the powdery particles are put into the hopper, they are smoothly and continuously supplied.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is for guiding a group of objects to be supplied, such as disc-shaped objects such as game medals and coins, and granular objects such as fertilizer, in a sliding state. The present invention relates to a sliding guide structure for a hopper, which is equipped with a sliding guide surface.

[Conventional technology]

As the above-mentioned sliding guide structure for the hopper, one in which the sliding guide surface of the narrow path portion or the curved path portion of the hopper is formed as a smooth surface is conventionally known (no literature can be provided).

[Problem to be solved by the invention]

However, in the above-mentioned conventional sliding guide structure, the objects to be fed into the hopper are transferred and guided while coming into contact with the smooth sliding guide surface, and as a result, the objects inside the hopper are fed out of the hopper. Although the position and posture of the group of objects to be supplied changes, the change is simple and small (particularly under conditions where a large amount of medals remain in the narrow or curved path of the hopper, the change in the position and posture of the group of objects to be fed changes). The racks are passed between the inner surfaces of a pair of hoppers that partially face each other in the horizontal direction, and these racks tend to cause a bridging phenomenon in which the medals passed cannot be repositioned in any direction, up, down, left, or right. sometimes stopped.

In particular, when the object to be supplied is a medal, for example, dirt adhering to the surface of the medal is likely to adhere and accumulate on the sliding guide surface.
This deposited dirt works to increase the coefficient of friction, making the medals gradually less slippery, and further aggravating the above-mentioned bridging phenomenon.

An object of the present invention is to ensure that the occurrence of cross-linking due to the supplied material can be reliably suppressed while always allowing smooth transition guidance of the supplied material.

[Means to solve the problem]

The sliding guide structure for a hopper according to the present invention includes a rotatable rotating body having a contact surface that contacts the object to be supplied, which is attached to the sliding guide surface of the narrow path portion or the curved path portion of the hopper. It is characterized in that a spherical body is rotatably attached to the rotating body and projects inside the hopper beyond the contact surface thereof, and the functions and effects thereof are as follows.

[For production]

For example, even under conditions where a large amount of objects are accumulated in the narrow or curved path of the hopper, the large weight of the accumulated objects acting on a part of the contact surface of the rotating body By the rotating body being rotated naturally, or
By forcibly rotating the rotary body using an electric motor or the like, the group of supplied bodies staying in the narrow path portion or the curved path portion is removed through the supplied bodies that are in contact with the contact surface of the rotary body. Each position and each posture can be changed entirely. Moreover, when the object to be supplied comes into contact with the spherical body of the rotating body, the spherical body rotates, and the position and posture of the object to be supplied, which is in contact with the spherical body, can be changed by the amount of rotation. can.

〔Effect of the invention〕

Therefore, by moving and guiding the group of objects to be fed while changing their positions and postures in a complicated manner through the rotation of the rotary body and the spherical body, even under conditions where a large amount of objects to be fed remain in the hopper, The occurrence of crosslinking due to these objects to be supplied can be avoided as much as possible, and the supply of objects to be supplied can be carried out satisfactorily over a long period of time without stopping.
