Description

[Detailed description of the invention] [Industrial application field] The present invention is applied to a timing belt used in a conveying process in which a conveyed object slides on a profile provided on the outer circumferential surface of the belt, especially an automatic merge-yan machine that aligns the merge-yan pie. This invention relates to a timing belt that reduces frictional resistance on the conveying surface of the timing belt used.

[Conventional technology]

In conveyor belts used in work processes where objects are slid on the belt and a certain number of objects are collectively passed on to the next process, objects that have stopped moving because they are being grouped together. There was a tendency for friction to occur between the belt and the conveying surface of the belt, causing squeaks and misalignment. In particular, the pies collided with each other in the automatic marzian machine, creating noise.

[Problem that the invention attempts to solve]

The method of using a material with low frictional resistance as a belt material reduces the function as a conveyor belt, and there are also problems such as poor fusion of the endless fused portion of the belt, and there are limits to improvement. Therefore,
There was a need for a simple method to reduce slip resistance on conveyor surfaces using conventional materials.

[Means of problem solving]

The purpose of this invention is to provide irregularities in the shape of a woven fabric surface on the conveyance surface, which was previously flat, so that the apparent stopping and gathering of conveyed objects on a moving conveyor belt can be performed smoothly. The structure is such that in a timing belt with teeth on one side, cuts are made at intervals from the other side to form a profile on the belt body located on the back side of the teeth, and the profile surface is It is made by forming irregularities on the surface of the woven fabric on the conveying surface of the transported object.

In the present invention, generally, unevenness on the surface of the woven fabric is transferred onto the conveying surface of the belt. The unevenness on the surface of the woven fabric is a linear protrusion in which each protrusion has a gently curved surface, and is dense. Moreover, in twill weave and satin weave, the exposed ratio of warp and weft yarns is different, and if the uneven surface is arranged in accordance with the sliding direction of the conveyance surface, the slip resistance can be significantly reduced. Further, even if the woven fabric is abraded during use, the unevenness of the woven fabric surface will not cause the protruding surfaces to become acute, and the effect can be maintained even if the woven fabric is abraded to some extent. Twill weave is particularly preferred as the woven fabric.

If necessary, a thin film of silicone resin or fluororesin may be further provided on the conveying surface.

〔effect〕

According to the present invention, the sliding resistance of the conveying surface of the profile is significantly reduced, and creaks and disturbances of conveyed objects no longer occur.

〔Example〕

FIG. 1 is a perspective view showing a part of an automatic merge-yan machine for aligning merge jumpers. Here, the timing belt 1 whose surface serves as the object conveying surface 4 has teeth 2 on one side thereof, and notches 6 at intervals, generally constant intervals, from the other side. is provided, thereby forming a profile 3 on the belt body located on the back side of the teeth. By providing such a cut, when the belt engages with the pulley 5 and rotates, the profile 3 also rotates smoothly. The tip of the cut is preferably hole-shaped so as not to apply a force that would cause a crack to the base of the profile 3, and in the illustrated embodiment, a buffer hole 7 is provided. The object conveying surface 4 on the surface of the profile 3 is formed with unevenness that is a transfer of the unevenness on the surface of the twill fabric of nylon fibers. In addition, 8 is a margin jumper, 9 is a stopper that stops the movement of the merge jumper until 13 merge jumpers 8 are aligned, 10 is a shaft that moves the stopper 9 up and down, and 11 is a solenoid that instructs the up and down movement of the stopper.

The starting angle of the merge jumper was determined by varying the inclination angle on the conveying surface of the profile, which had irregularities that matched the surface of the woven fabric. Test at 20℃ and humidity
I went with 60%. As a result, the inclination angle at which Margeyampai started sliding was 35 to 40 degrees. On the other hand, the sliding angle of the conventional conveying surface, which is a smooth surface without the textured surface of the woven fabric, was 20 to 25 degrees.

Therefore, in the present embodiment, the pies are not disturbed or jumped out, and the noise caused by the merging pies colliding with each other is eliminated.
