Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an industrial brush, particularly a roll-shaped or plate-shaped industrial brush used for descaling metals or cleaning conveyor belts.

[Conventional technology]

Conventionally, roll brushes used for descaling metals, for example, have a wooden core rod with a predetermined length and diameter, with a number of tuft holes drilled on its circumference, and hard metal wires are bundled into the tuft holes. It was made by press-fitting and fixing a single brush. This roll brush is installed in a descaling device equipped with a driving mechanism that presses against a metal surface while rotating and moves the brush. In addition, as a plate-shaped brush used for cleaning conveyor belts, etc., bristle holes are bored at predetermined intervals on one longitudinal edge of a plate having a predetermined length and width, and the brush is inserted into the bristle holes. It was made by press-fitting and fixing a single unit. The plate-shaped brush is used by being fixed to a suitable support part, for example, by being pressed against the upper surface of a running conveyor belt. In addition to hard steel wires, soft metal wires such as brass wires, or non-metallic wires such as fibers, synthetic fibers, or animal hair have been used as the brushes used in these industrial brushes. Single brushes like this are formed into a fixed bundle, and each one is press-fitted into a flocking hole drilled on the circumference of a core rod or the side end of a plate, and this work can be done manually or with a flocking machine. I went there by

[Problem that the invention seeks to solve]

However, with conventional industrial brushes of this type, the material on which the brush itself is planted is wood, so the brush itself is not secured sufficiently and easily comes off, making long-term use difficult. Or, when it wears out, the entire thing must be replaced with a new one, which is uneconomical. When planting a single brush with a flocking machine, a wire bent into a U shape is used at the base of the brush, and this wire is designed to lock into the flocking hole and prevent it from coming out. However, this retainer cannot resist the strong thrust force. Furthermore, industrial brushes made of wood are sensitive to heat and lack heat resistance. In addition, in the manufacture of this type of industrial brush, in order to change the pitch of the brush itself or to manufacture one in a spiral arrangement, it is necessary to manufacture each type of brush, which is not suitable for mass production.

[Means for solving problems]

The present invention aims to solve the above-mentioned problems all at once, and for this purpose, at least two parallel cut lines each having a certain length are formed at a predetermined interval on the edge of a metal substrate. forming at least two band ring parts, each of the band ring parts protruding and curving in the front and back directions of the substrate to form a ring part, and a single brush made of a bundle of wire rods is inserted into the ring part. Thereafter, an industrial brush and a method for manufacturing the same were constructed in which the band ring portion was pressed against a single brush unit and fixed in such a way that it could not be removed.

[Effect]

According to the present invention, after inserting the brush into the band ring part, the band ring part is pressed from the outside, so that the brush unit is firmly fixed to the substrate and does not easily come off. By connecting a plurality of substrates on which individual brushes are flocked in this way, it is possible to form a roll brush of a desired length or a desired block type brush. By connecting the brushes in the axial direction, it is possible to configure a roll brush in which the single brushes are arranged in a spiral manner.

〔Example〕

The present invention will be explained below based on illustrated embodiments. 1 and 2 are front views showing two types of substrates 3 and 3a implanted in the annular portion 2 of the single brush 1, respectively. The substrates 3, 3a are made of a metal plate having a predetermined circular shape or a polygonal shape close to a circular shape, and a shaft hole 5 for inserting a shaft rod 4 (FIG. 5) is bored in the center thereof. Annular portions 2 are formed at regular intervals on the edges of the substrates 3, 3a over the entire circumference. This annular part 2 has at least two parallel cut lines of a certain length radially formed on the edges of the substrates 3 and 3a, and a band ring part 6 is formed between the cut lines facing each other in the radial direction. , 6,
The band ring parts 6, 6 are respectively protruded and curved in the front and back directions of the substrates 3, 3a, and the brush unit 1 is inserted into the ring part 2 (see FIG. 5) formed by the band ring parts 6, 6. It has been made possible.
The number of band ring parts 6 is arbitrary, and it is sufficient if there is at least one band ring part 6 on one side. Then, the annular portion 2 and the shaft hole 5
A semicircular hole 7 into which the base of the brush unit 1 is inserted is provided between the brush body 1 and the brush body 1 . The shaft hole 5 has a hexagonal shape, and at least two of its opposing apex angles 5a are arranged on the same line as the center line B of the brush unit 1 that faces each other in the diametrical direction. However, the apex angle 5a of the shaft hole 5 of the substrate 3a shown in FIG.
It is arranged on the center line C that connects the substantially central portions of the individual brushes 1. 4A is a front view of the substrates 3 and 3a of FIG. 1, and FIG. 4B is a front view of the substrates 3 and 3a of FIG. 2. Therefore, a roll brush is constructed using a plurality of each of these two substrates 3, 3a, and as shown in FIG. The annular portions 2 are arranged in a staggered manner on both the front and back surfaces of the substrates 3 and 3a. When the substrates 3 and 3a are connected in this way, the brushes are densely packed as a whole, but if it is necessary to make them sparse, a spacer made of a disc or the like of an appropriate thickness is interposed between the substrates 3 and 3a. It's okay. The individual brushes 1 are inserted into the annular portions 2, but this operation is performed by a hair transplanter. Since this flocking machine is already known and for public use, its detailed explanation will be omitted. However, a wire body of a predetermined length is bundled and folded in half, and the bent part is connected to the U-shaped wire 1a at the end. Push into the annular part 2 with a rod-shaped body held by
The work of pulling out the rod-shaped body while leaving it in the hole 7 is performed for each annular part, and is performed while rotating the substrates 3, 3a by a predetermined angle. After each of the brush units 1 is implanted on the substrates 3 and 3a, the substrates 3 and 3a are sandwiched by a press, the annular portion 2 is pressed, and the brush units 1 are tightened and fixed. As a result, the wire 1a takes on a substantially square shape and is prevented from coming out.

FIG. 6 shows the external appearance of a roll brush 8 constructed by connecting the substrates 3, 3a formed as described above through a shaft rod 4 and a fastening fitting 4a. Also,
In FIG. 9, the entire brush of the roll brush 8a is spirally shaped, which is different from the brush shown in FIG. 6 in which the entire brush is arranged in a staggered manner. To construct the spirally arranged brush, for example, substrates 3b and 3c shown in FIGS. 7 and 8 are used. Each of the substrates 3b and 3c has a single brush 1 implanted in every other annular body 2, and when these substrates 3b and 3c are connected alternately, a roll brush 8a shown in FIG. 7 is formed. It is. That is, these substrates 3
The opposing apex angles 5a of the respective shaft holes 5 of b and 3c are positioned at different angles (for example, 18 degrees in the drawing).
At the same time, since the single brushes 1 are installed in every other annular portion 2, when these are connected to form the roll brush 8a, the individual brushes 1 are arranged spirally in the circumferential direction. be.

10 and 11 show a plate-shaped brush, with FIG. 10 being a front view and FIG. 11 being a back view. This plate-shaped brush 8b has an annular portion 2 arranged at regular intervals on one end of a substrate 3c made of rectangular metal, and individual brushes 1 are implanted in each of the annular portions 2 in the same manner as in the previous example, and The annular portion 2 is pressed with a press from the front and back directions, and the brush unit 1 is tightened and fixed to the substrate 3c. A semicircular strip 9 is formed in the longitudinal direction on this substrate 3c by press molding, and this strip 9 functions as a reinforcement and also as a guide for engaging with a support portion or forming a block type brush. Become.

The brush unit 1 is shown in Figs. 1, 2, and 10.
Figures 7 and 11 show comparatively soft materials such as synthetic fibers, and Figures 7 and 8 use curly bundles of curled brass wire. Further, as described above, the brush unit 1 may use fiber or animal hair as the linear body.

Next, the manufacturing method according to the present invention is substantially clear from the above description, and detailed explanation thereof will be omitted. That is, in the method for manufacturing an industrial brush of the present invention, at least two parallel score lines each having a certain length are formed at a predetermined interval on the edge of a substrate, and at least two score lines are formed between the opposing score lines. forming a band ring portion, causing the band ring portion to protrude and curve in both directions of the front and back sides of the substrate;
The brushes are inserted into the approximately circular annular portions formed by the curved band ring portions, and then the band ring portions are pressed against each other from the outside to tighten and fix the brush units so that they cannot be removed. This is a method for manufacturing industrial brushes.

〔Effect of the invention〕

According to the present invention described above, an annular portion is formed at the edge of a metal substrate, a single brush is inserted into the annular portion, and the annular portion is pressed from the outside to tighten the brush onto the substrate. Since the brush is attached and fixed, the brush alone is firmly tightened and fixed to the board and will not easily come off. In addition, the substrate can be easily mass-produced by press molding, and brushes can be automatically and mechanically produced using a flocking machine on this substrate, and industrial brushes can be mass-produced using one or more of these, reducing costs. bring. Since a roll brush or block type brush can be constructed by connecting multiple units, when a part of the brush is worn out, it is necessary to replace only that unit and replace the roll brush or block type brush as a whole. It is economical without any hassle. Furthermore, it is possible to arrange the brushes in a roll brush in a spiral manner by setting the brush spacing to every other brush, and by interposing an appropriate spacer between the connected substrates, the pitch spacing between the brushes can be widened. It is possible to provide industrial brushes suitable for various uses. In addition, since an industrial brush for descaling can be formed by using a metal plate as the substrate and using a single brush as a wire bundle, since the material is metal, it has extremely high heat resistance and has a long service life.
