Abstract

(57) [Summary] [Purpose] To reduce the frictional resistance of the belt to the guide rail. [Structure] A pipe 13 is fitted on the outer side of a horizontal bar 12 located between an end of a spiral filament 11 and a link 14 in a belt A for a net conveyor, and the pipe is brought into contact with a guide rail to reduce frictional resistance. .

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a belt for a net conveyor that conveys various materials and products in factories and the like.

[0002]

[Prior art]

 As shown in FIG. 3, a conventional belt for a net conveyor has spiral filaments 1 of a certain length wound in a spiral shape in which steel wires are wound in parallel, and the opposing edges of adjacent spiral filaments 1 are arranged. Along with the overlap, the connecting edges of the spiral filaments 1 are bent and connected by inserting the connecting horizontal bar 2 made of a thick steel rod inside the overlapping facing edges.

A chain link 3 is attached to both ends of the horizontal bar 2.

The chain link 3 described above is formed by bending a tough metal plate into a U-shape, inserting a bending intermediate portion between the ends on both sides, and providing the bending portion on both sides. The horizontal bar 2 is passed through the hole 4. The bulge portions 5 provided at both ends of the horizontal bar 2 prevent the link 3 from coming off from the horizontal bar 2.

In the net conveyor configured as described above, the links 3 on both sides are run on sprockets (not shown), and as shown in FIG. 6 to support.

The upper edge of the guide rail 6 is covered with a covering material 7 made of synthetic resin having good sliding properties.

[0007]

[Problems to be Solved by the Invention] According to the above net conveyor belt, when the belt conveyor is constructed, the backsides of both end portions of the spiral wire are supported by being supported on the upper surface of the guide rail. Friction resistance is extremely high due to the slip running of the strip.

For this reason, there has been a problem that the power required for traveling is significantly increased and the life is shortened due to friction.

Therefore, an object of the present invention is to remarkably reduce frictional resistance and prolong the life.

[0010]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the present invention arranges a large number of spiral filaments so that the opposite edges overlap each other, and inserts a horizontal bar inside the overlapping opposite edges to form the spiral wire. In a belt for a net conveyor in which the opposite edges of the strip are bendably connected and chain links are attached to both ends of the horizontal bar, the end of the horizontal bar located between the end of the spiral filament and the link. A structure in which a pipe is fitted to the outside of the section is used.

[0011]

[Action]

 With the above structure, the pipe is brought into contact with the upper edge of the guide rail to support the back surface of the belt, and the friction resistance is reduced by the pipe that freely rotates with respect to the horizontal bar.

[0012]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a large number of spiral filaments 11 are arranged so that the opposing edges overlap each other, and the spiral filaments 11 are thicker than the spiral filaments 11 inside the overlapping opposing edges. A belt A for a net conveyor is formed by inserting a horizontal bar 12 made of steel wire and connecting opposite edges of the spiral filament 11 in a bendable manner.

Pipes 13 which rotate freely are fitted on the outer sides of both ends of the horizontal bar 12 protruding from both ends of each spiral filament 11.

The pipe 13 is made of a material having excellent wear resistance.

Further, links 14 for chains are attached to both ends of the horizontal bar 12.

In the illustrated case, the link 14 is formed by bending a metal plate into a U-shaped plane so that the facing distance on both sides becomes larger toward the open end side. While inserting the bent tip of No. 14, the holes 15 provided at both ends of the link 14 and both sides of the bent tip are aligned with each other, and the horizontal bar 12 is inserted into the hole 15, and then the horizontal bar is inserted. Although the bulging portions 16 are provided at both ends of 12 to prevent the link 14 from coming off from the horizontal bar 12, the chain link may be attached by a method other than the above.

The net conveyor belt A is run by mounting the links 14 on both sides on sprockets (not shown).

Reference numeral 17 in the figure is a guide rail laid on both sides of the carrier-side lower surface of the net conveyor belt A. The guide rail 17 receives the outer peripheral surface of the pipe 13 by contacting the outer peripheral surface thereof. Reference numeral 18 denotes a link-shaped side piece for preventing an article from falling, which is interposed between the spiral filament 11 and the pipe 13 and penetrates the horizontal bar 12.

[0020]

【effect】

 Since the belt for the net conveyor according to the present invention is configured as described above, the frictional resistance to the guide rail is significantly reduced by the pipe, smooth running is ensured, and the life of the guide rail and the belt is extended. .

Claims (1)

[Scope of utility model registration request] 1. A plurality of spiral filaments are arranged so that the opposing edges overlap each other, and a horizontal bar is inserted into the inside of the overlapping opposing edges to bend the opposing edges of the spiral filaments. In a belt for a net conveyor, which is connected to each other and has chain links attached to both ends of the horizontal bar, a pipe is fitted outside the end of the horizontal bar located between the end of the spiral filament and the link. A belt for net conveyors that is characterized by that.
