Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a belt conveyor, and particularly to a knife edge type conveyor belt that reduces the recess of the conveyor belt from the conveyor surface at its end.

(Prior art) In a typical belt conveyor, the conveyor belt is guided in a folded manner from the upper side to the lower side or from the lower side to the upper side by pulleys provided at both ends, and the pulleys at both ends have relatively large diameters. For this reason, there is a problem in that the conveyor belt is recessed from the conveyor surface at the pulley portions at both ends.

To solve this problem, instead of a pulley,
Knife edge type belt that reduces the dent of the conveyor belt from the conveyor surface at the end by guiding the conveyor belt from the upper side to the lower side or from the lower side to the upper side using a knife member such as a small diameter round bar. A conveyor was considered.

In the case of this knife edge type belt conveyor,
Since the conveyor belt slides on the knife member, there is a problem in that the conveyor belt tends to shift laterally at this portion, causing the conveyor belt to meander (deviate).

(Problem to be solved by the invention) To prevent the above-mentioned meandering (unbalanced) conveyor belt,
Generally, this is done by adjusting the pulleys at both ends, but in the case of the knife edge type, there are no pulleys at both ends, so another method is used to solve the problem of meandering (unbalanced) conveyor belt. It is required to be resolved.

The present invention has been developed in view of these points, and uses a knife member instead of a pulley to guide the conveyor belt in a folded manner from the upper side to the lower side or from the lower side to the upper side. This invention attempts to prevent meandering (deviation) of the conveyor belt in a knife edge type belt conveyor that reduces the recess of the conveyor belt from the conveyor surface at the end.

[Structure of the invention] (Means for solving the problem) The belt conveyor of the invention is a belt conveyor in which a conveyor belt 21 is supported on the upper surface of a support plate 2 and moved on this support plate 2. A knife member 11 is provided on at least one end of the support plate 2 to guide the conveyor belt 21 in a folded manner from the upper side to the lower side or from the lower side to the upper side.
A guide member 25 is disposed so as to protrude toward the leading end of the transport belt 21 and to face both edges of the transport belt 21 .

(Function) In the belt conveyor of the present invention, since the guide member 25 faces the edges on both sides of the conveyor belt 21, meandering (deviation) of the conveyor belt 21 is prevented.

(Embodiment) An embodiment of the belt conveyor of the present invention will be described with reference to the drawings.

In Figures 1 to 5, 1 is a conveyor frame, and this frame 1 is made of a metal plate such as stainless steel, and is made by integrally bending side plates 3 downward from both sides of the support plate 2 in the width direction. Although not shown, cross-jointing rods are arranged between the side plates 3 on both sides at a predetermined interval in the length direction (front-back direction),
This cross-joint rod is reinforced by fixing side plates 3 on both sides to both ends thereof, and is supported in a horizontal or inclined manner by a pair of front and rear legs 4 fixed to the side plates 3 on both sides.

A plate-shaped knife member 11 made of synthetic resin is attached to a clamping plate 12 made of a metal plate such as stainless steel and a plurality of countersunk screws 13 at the lower part of the support plate 2 at both longitudinal ends of the frame 1. The curved tip edge of this knife member 11 protrudes from both ends of the support plate 2, and a drive pulley 14 is mounted below the longitudinally intermediate portion of the frame 1. Snut rollers 16 are pivotally supported via the support frame 15, and are located above both sides of the drive pulley 14, and are further provided near both longitudinal ends of the frame 1. The end rollers 17 are each supported by a shaft, and the lower part of the frame 1 is located between the end roller 17 and the drive pulley 14 (in this embodiment, between one end roller 17 and the drive pulley 14). A return roller 18 is pivotally supported, and the drive pulley 14 is rotated by a drive mechanism including a motor (not shown) provided on a support frame 15 of the frame 1.

These knife members 11 and pulleys 14
An endless conveyor belt 21 made of a wide flat belt is wound around the rollers 16, 17, and 18, and as the drive pulley 14 rotates, the conveyor belt 21 passes between the knife members 11 at both ends of the frame. 1
The conveyor belt 21 that moves on the upper surface of the support plate 2 supports and conveys articles (not shown). ing.

Then, in the present invention, guide members 25 made of the same synthetic resin are fixed to both sides of the knife member 11 at both ends with bolts 26, and the tip of each guide member 25 is attached to the tip side of the knife member 11. The conveyor belt 21 protrudes from the top of the guide member 25, thereby guiding the tip of each guide member 25 in a folded manner from the upper side to the lower side or from the lower side to the upper side at the curved tip edge of the knife member 11. The end faces of the edges on both sides are opposed to each other.

In this way, the guide member 25 faces the edge end faces on both sides of the folded portion of the conveyor belt 21, so that meandering (deviation) of the conveyor belt 21 is prevented.

Note that here, the tip of the guide member 25 is merely made to protrude toward the tip of the knife member 11, but in addition to the tip of the knife member 11, it may also be made to protrude above or below the knife member 11. good.

[Effect of idea]

As described above, according to the present invention, the leading end of the guide member is attached to both edges of the conveyor belt that is guided in a folded manner from the upper side to the lower side or from the lower side to the upper side at the leading edge of the knife member. Since they face each other, meandering (deviation) of the conveyor belt can be prevented.
