Description

Detailed Description of the Invention [Field of Industrial Application] The present invention improves belt performance and improves belt performance in toothed belts, V-belts, flat belts, etc. used when conveying soft objects or conveying them while grinding them. This invention relates to a conveyor belt with brushes that increases brush density without reducing belt life.

[Prior art]

Conventional brushed belts have a channel brush that is either directly grafted onto the profile or soldered to a metal plate, and is bolted to the belt so as to sandwich the brush.

In the method of direct hair transplantation, as shown in FIG. 4, a round hole 9 having a depth approximately twice the hole diameter is bored in the profile 4, and the hair 8 is directly transplanted into the round hole 9. This method not only has a low flocking density but also requires a lot of time and effort, resulting in high costs.

The method of attaching the channel brush is that the metal plate to which the channel brush is soldered is heavy, and the belt is sandwiched between this metal plate and another metal plate attached to the back of the belt, and the bolts are tightened. The weight was placed on the belt, causing large vibrations, and the belt was tightened, making it easy to break. Furthermore, the channel metal fittings protruding onto the metal plate sometimes came into contact and damaged the conveyed object.

[Problem that the invention seeks to solve]

Using a channel brush with high flocking density,
There was a need for a brushed conveyor belt that would not add much weight to the belt and would not shorten the life of the belt itself.

[Means for Solving Problems] and [Operation] The present invention solves the above object, and by providing a groove in the profile and pushing the channel brushes into the grooves, a large number of channel brushes with high flocking density can be installed. It can be fixed without putting any strain on the belt body.

The groove provided in the profile surface is the same as or slightly narrower than the width of the channel fitting to be embedded, and one or more channel fittings are pushed in side by side. Alternatively, the side surfaces of the channel fittings of two or more channel brushes may be welded together and pushed into the groove. The channel fitting is firmly fixed by press-fitting it into the narrow groove, but it is also possible to undercut the groove or use adhesive to fix it. Preferably, the groove is as deep as or deeper than the channel fitting. In this way, the channel metal fittings are completely hidden in the groove, and there is no risk that the metal fittings will damage the conveyed object.

The direction in which the channel brush is attached is usually the direction across the belt, but it may be in the longitudinal direction of the belt or in other directions.

If the attachment area of the profile to the belt body is large, it will be difficult for the belt to rotate smoothly around the outer periphery of the pulley. Therefore, the attachment area should be small, the attachment interval should be large, and the surface with grooves for brush attachment should be widened. It takes. In the case of a toothed belt, it is preferable that the attachment area of one profile to the belt body does not exceed the area of the root of one tooth.

〔effect〕

According to the present invention, the brush can
~5 times the density was obtained, the belt life was extended, and the brushes were no longer cut before their lifespan. In addition, since the brush is less likely to wear out, there is less misalignment of the conveyed object, and even brushes with small wire diameter bristles can be used without fading, allowing soft conveyed objects such as copper, aluminum, and plastic products to be used. There is no longer any risk of damaging the surface of the transported object even when polishing the object. Furthermore, since the channel metal fittings are buried within the profile, the conveyed object will not be damaged.

〔Example〕

FIG. 1 is a perspective view showing a cross section of a conveyor belt with a brush according to the present invention. 1 is a belt body, 2 is a tooth, and 3 is a tensile member. Reference numeral 4 denotes a profile attached to the conveying surface of the belt, which has an inverted convex shape whose attachment area to the belt body 1 is smaller than the attachment area of the teeth 2 to the belt body 1, and has three rows of grooves 5 carved on the outer peripheral surface. A channel brush 6 was press-fitted into this groove 5. 7 is a channel metal fitting, and 8 is a hair.

The embodiment shown in FIG. 1 is suitable for conveying an object whose outer peripheral surface is flat, but if the outer peripheral surface of the object is curved, an arc-shaped channel brush 16 as shown in FIG. It was pressed into a profile 14 having a groove 15 of a shape corresponding to 17.

FIG. 3 is a cross-sectional view of a channel brush suitable for conveying objects shaped like a triangular prism. In addition, channel brushes of various shapes can be embedded according to the shape of the object to be transported.
