Abstract

PURPOSE:To prevent a lowering of the life of a belt body by disposing a groove on a profile mounted on the outer peripheral surface of a conveying belt, and pushing a channel brush in the groove to fix a lot of channel brushes having high bristle planting density. CONSTITUTION:A profile 4 is discontinuously disposed on the outer peripheral surface of a conveying belt 1, and channel metal fittings 7 of a channel brush 6 are buried and fixed in grooves 5 cut in the profile 4. Thus, the brush can have a density three to five times as much as that of the conventional round hole planting, so that weight put on the belt is not much thus not lowering the life of the belt body.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention is aimed at improving belt performance and the like in toothed belts, ■ 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 channel brushes that are either grafted directly onto the profile or soldered to a metal plate, and then bolted together to sandwich the belt.

As shown in Fig. 4, the direct hair transplanting method involves drilling a round hole 9 in the profile 4 with a depth approximately twice the hole diameter.
Hair 8 was directly implanted inside. This method not only had a low flock density, but also required a lot of effort and cost.

The method of installing a 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, which caused a lot of vibration, and because the belt was tightened, it was easy to break the belt. Furthermore, the channel metal fittings protruding onto the metal plate may come into contact and damage the conveyed object.

[Problem that the invention seeks to solve]

There was a need for a conveyor belt with brushes that uses channel brushes with a high density of flocking, does not add much weight to the belt, and does not reduce the life of the belt body.

[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 buried, 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 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, so it is preferable that the attachment area is small and the surface provided with the groove for brush attachment is wide. 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 density of the brushes is 3 to 5 times higher than that of conventional round hole planting, the belt life is extended, and the brushes are not cut off before their lifespan. In addition, since the brush is less likely to wear out, misalignment of objects to be transported is reduced, and even brushes with small wire diameter bristles can be used without bending, allowing soft objects such as copper, aluminum, and plastic products to be transported. There is no longer any risk of damaging the surface of the transported object even when performing polishing work. Furthermore, since the channel metal fittings are buried within the profile, the conveyed objects 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, the attachment area to the belt body 1 is smaller than the attachment area of the teeth 2 to the belt body 1, and three rows of grooves 5 are 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 arcuate channel brush 16 as shown in FIG. Profile 14 with a groove 15 of a shape corresponding to 17
It was pressed inside.

FIG. 3 is a 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.
