Abstract

PURPOSE:To prevent a belt in a belt conveyer from zigzagging, optimize the tension of the belt and enable the position of an article conveyed by the belt to be well controlled. CONSTITUTION:A plurality of projections 21a projectingly provided on the surface of a drum 2a are sequentially put in and out of a plurality of recesses 11a in the inner surface belt 12a of a belt 1a sequentially by the rotation of the drum 2a so that the belt 1a can travel surely on the outer periphery of the drum 2a without slipping or zigzagging thereon.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt conveyor capable of preventing the belt from meandering, optimizing the belt tension, and controlling the position of articles conveyed by the belt.

[0002]

2. Description of the Related Art Conventionally, a belt of a belt conveyor travels due to friction with a rotating drum, which causes meandering of the belt and damages a rotation driving motor for the belt and the drum, resulting in excessive belt tension and a bearing. Problems such as damage to the vehicle and increased loss of drive power are occurring. In addition, it is virtually impossible to control the position of an article conveyed by a belt for the purpose of automating the assembly.

[0003]

SUMMARY OF THE INVENTION Therefore, the present invention has been made in order to eliminate the above-mentioned conventional drawbacks, and prevents friction at the contact surface between the belt and the drum and further conveys the article by the belt. It is a subject to enable position control of.

[0004]

Therefore, in the present invention, firstly, a belt having a plurality of concave portions on its inner surface and a drum having a plurality of convex portions on its surface that can be fitted into the respective concave portions of the belt are provided. Secondly, the present invention is intended to solve the above problems by providing a plurality of convex portions or concave portions on the outer surface of the belt.

[0005]

According to the present invention, with the above construction, when the drum rotates and the belt moves on the outer periphery of the drum, a plurality of recesses provided on the inner surface of the belt are provided on the surface of the drum. Since the convex part fits in and friction does not occur on the contact surface between the belt and the drum, the belt is prevented from meandering.Because the convex part of the drum surface moves in and out of the concave part on the inner surface of the belt, It is possible to optimize such tension.

Further, by providing a plurality of concave portions or convex portions corresponding to a plurality of convex portions or concave portions provided on the outer surface of the belt on an article to be conveyed by a belt or a pallet on which the article is placed, Position control becomes possible.

That is, the belt is prevented from meandering to prevent damage to the belt, the drive motor, etc., the belt tension is optimized to prevent damage to the bearings, reduce drive power loss, etc. This has the effect of enabling position control of the articles to be processed and promoting automation.

Embodiments Hereinafter, in order to further clarify the gist of the belt conveyor according to the present invention, embodiments thereof will be described with reference to the drawings.

A first embodiment will be described with reference to FIG. C
Reference numeral 1 denotes a belt conveyor according to the present invention, which is an endless belt in which a synthetic resin outer surface belt 13a is bonded to a synthetic resin inner surface belt 12a in which a plurality of recesses 11a are provided at equal intervals in a length direction and a direction perpendicular to the length. Belt 1a and a cylindrical drum 2a that abuts against the inner surface belt 12a by projecting a plurality of projections 21a that can be fitted into the respective recesses 12a of the inner surface belt 12a.

Next, regarding the operation of this embodiment, by the rotation of the drum 2a, the respective convex portions 21a of the drum 2a sequentially move into and out of the respective concave portions 11a of the inner surface belt 12a of the belt 1a, and the belt 1a becomes the drum 2a. It is possible to travel accurately without slipping or meandering around the outer periphery of the.

A second embodiment will be described with reference to FIG. C
2 is a belt conveyor according to the present invention, which is made of synthetic resin in which a plurality of convex portions 14b are provided on an inner surface belt 12b made of synthetic resin in which a plurality of concave portions 11b are provided at equal intervals in a length direction and a direction perpendicular to the length. An endless belt 1b to which an outer surface belt 13b is adhered, and each recess 11b of the inner surface belt 12b.
It is composed of a cylindrical drum 2b having a plurality of protrusions 21b that can be fitted into the surface of the drum 2b.

Next, regarding the operation of this embodiment, by the rotation of the drum 2b, the respective convex portions 21b of the drum 2b sequentially move into and out of the respective concave portions 11b of the inner surface belt 12b of the belt 1b, and the belt 1b becomes the drum 2b. By accurately traveling without sliding or meandering around the outer periphery of the outer belt 13b, and by providing a plurality of concave portions into which the convex portions 14b of the outer surface belt 13b can be fitted in the article to be conveyed by the belt 1b or the pallet on which the article is placed. It is possible to control the position of the article to be conveyed.
