Abstract

PURPOSE:To keep both side surfaces of a belt and the inner surfaces of side plates of a conveyer from contacting each other by wrapping a wide belt having projecting portions formed on the inner peripheral surface round a plurality of rolls shaped corresponding to the shape of the inner peripheral surface. CONSTITUTION:A wide belt 1 having projecting portions 3 of an arbitrary shape formed on the inner peripheral surface is wrapped round a plurality of rolls shaped corresponding to the shape of the inner peripheral surface. The projecting portions 3 are fitted in small-diameter portions 12 of the rolls 10, and the belt is rotated with the side portion 14 of the projecting portion 3 brought into contact with a shoulder portion 13 of the small-diameter portion 12. In this arrangement, even if the bilateral spacing is a little wrongly adjusted or earth and sand adhere to the rolls 10, the wide belt 1 will not slip sideways. Furthermore, the belt is not damaged, and heat is not generated due to contact of the side of the belt 1 with the inner surface, and the belt conveyer is smoothly operated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a belt conveyor, and more particularly to a belt conveyor device that prevents sideways slipping of a belt.

Conventionally, belt conveyors in which a wide belt is wound between a plurality of rolls have been widely used in various fields. However, with these belt conveyors, it is well known that it is difficult to adjust the left and right distance between the rolls that wind the belt, and if the left and right distance is incorrectly adjusted, the belt will skid in one direction and run onto the edge of the roll. This may cause damage to the inner peripheral surface of the belt, or the side surface of the belt may come into contact with the inner surface of the conveyor side plate.
Not only did it damage the sides of the belt, but in the case of strong contact, the contact area could overheat and even cause a fire.

Moreover, even if the left and right spacing is adjusted accurately, in the case of a conveyor that conveys moist earth, sand, powder, etc., fine earth, sand, powder, etc. rain on the rolls and harden. The current situation is that the belt slips due to the roll diameter becoming partially large.

Therefore, in the present invention, in view of this problem, a wide belt having a convex portion of an arbitrary shape formed on the inner peripheral surface is wound around a plurality of rolls each having a shape corresponding to the shape of the inner peripheral surface of the wide belt. ,
It is an object of the present invention to provide a belt conveyor device configured so that both side surfaces of the wide belt and the inner surface of the conveyor side plate do not come into contact with each other.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

(a) In the negative embodiment of the wide belt l, polyester fibers 1412 having an arbitrary radius and length are provided at both ends of the back surface with a cross-sectional shape in the width direction of a substantially rectangular shape and a length corresponding to the length of the polyester fibers 2. The convex portions 3 corresponding to the shape of the convex portions 3 are joined, and the polyester fibers 5 are coated thereon so as to follow the shape of the convex portions 3, and the belt in this state is further impregnated with polyurethane, and connected in an endless manner. Obtain a wide belt l.

As a second embodiment, protrusions 3 having a substantially rectangular cross-sectional shape in the width direction are integrally formed on both end faces of a plate 6 made of a rubber material or the like having an appropriate width and length, and the plate 6 and protrusion 3
An arbitrary core material 7 is provided inside. A plate 8 made of polyester fibers impregnated with polyurethane is bonded to the other surface of the plate 6 and connected endlessly to form a wide belt 1.
get.

Although the material etc. of the above-mentioned example is described as a light load conveyor, it should be noted that the belt material and configuration may differ depending on the load, and the shape of the convex part of the main part is not limited to the approximately rectangular shape in the example. , approximately semicircular, approximately triangular, approximately trapezoidal, etc. (the shape is not limited to the examples).

The location of the convex portion 3 is not limited to the end portion either.

(b) The roll 10 has both ends shaped to follow the shape of the inner circumferential surface of the wide belt I, that is, the portion corresponding to the convex portion 3.3 has a small diameter 12, and the shoulder portion of the small diameter portion 12.12 has a diameter of 13°. 1
The convex portions 3 of the wide belt l are in contact with the side portions 14 and 14 of the wide belt l to prevent the belt from slipping sideways. 15 is a conveyor side plate.

As described above, in the present invention, a wide belt I having a convex portion 3 of an arbitrary shape formed on the inner peripheral surface is wound around a plurality of rolls 10 having a shape corresponding to the shape of the inner peripheral surface of the wide belt I. Since this belt conveyor device is configured so that both sides of the wide belt l do not come into contact with the inner surface of the conveyor side plate 15, conventional conveyors are prone to problems caused by maladjustment of the gap between the left and right rolls when the wide belt is wound between the rolls. For example, a belt may ride on the edge of a roll and cause problems in conveyance.
The belt may become damaged due to damage to the back side of the belt, or moisture-containing fine dirt or powder adhering to the roll and hardening due to the pressing force of the rotating belt pressing against the roll, causing a portion of the roll to become larger. However, in the present invention, the convex part 3 of the wide belt l fits into the small diameter part 12 of the roll 10, and the side part 14 of the convex part 3 contacts the shoulder part 13 of the small diameter part 12 and rotates. Even if the left and right spacing is slightly adjusted incorrectly, or dirt or the like adheres to the rolls, the wide belt l will not skid sideways, so there is no risk of the side surface of the belt coming into contact with the inner surface of the conveyor side plate 15, so the belt will not be damaged. The belt conveyor has truly remarkable effects such as no heat generation due to contact with the side plate and smooth operation of the belt conveyor.
