Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a brush roller used for conveying and polishing agricultural products such as potatoes and onions.

(Prior Art) Generally, when agricultural crops such as rainbows, potatoes, onions, etc. are harvested from the field and then put into a sorting machine for sorting, a brush roller with brushes is used as a means of conveying the harvested products. A normal brush roller, in which the brushes are installed perpendicular to the axis of the roller, does not have the ability to transport agricultural products in the direction of the axis of the roller. (Crops) are conveyed by rolling using their own weight, but due to differences in the weight of the objects being conveyed, the speed of conveyance (rolling) is not constant, and as a result, the objects being conveyed may not be polished sufficiently. Occur.

Therefore, in order to solve the above-mentioned problems, the present applicant developed a conveyor polishing device (Special Publication No. 59-
Publication No. 37068). The rotating body of the brush in this device has a brush-like body made of elastic brushes tilted in one direction on the outer periphery of the rotating shaft, and the elasticity of the tilted side of the brush allows the object to be transported to be On the other hand, it is possible to generate a conveyance force in the axial direction on the tilting side, and the polishing ability of the conveyed object can be improved by increasing the frictional force.

Therefore, one possible method for tilting the brush in one direction as described above is to set it perpendicular to the axis and then lay the tip of the brush in one direction.
In this case, there is no function of pushing the object to be conveyed toward the tilting side, that is, the elastic force of the brush, and the polishing ability is also small, and it is very difficult to lie the tip of the brush in one direction.

(Problems to be Solved by the Invention) In view of the above-mentioned conventional circumstances, the present invention has developed a simple rotary roller having an inclined brush that effectively exerts the force of pushing out the conveyed object in the axial direction. The purpose is to provide a manufacturing method.

(Means for Solving the Problems) The technical means of the present invention for solving the above problems is to provide installation holes for installing brushes in the roller body by drilling them at an angle in accordance with the inclination angle of the brushes. A brush is inserted and inserted into the planting hole, and the brush is planted so as to protrude obliquely by a desired length from the surface of the roller body.

The inclination of the planting holes drilled in the roller body may be formed at a desired angle with the axis along the longitudinal direction of the roller body, or may be inclined at a desired angle in the circumferential direction in addition to the above-mentioned axis direction. to form.

Also, to fix the brush that is inserted into the planting hole, fix it by pouring adhesive such as glue into the planting hole, or by fixing the brush to the substrate with adhesive or pins, etc. Fit into the planting hole and insert approximately 1/3 of the total length of the brush into the planting hole to secure it.

(Function) A hole for installing the brush is formed in the roller body so as to be inclined in the axial direction and circumferential direction, and the brush is installed in the hole and extends to an appropriate length outside the roller body. This makes the angle of inclination of the brush constant and improves the elastic force acting on the brush.

(Embodiment) Hereinafter, an embodiment of the present invention will be described based on the drawings. In the drawing, 1 is a roller body, 2 is a planting hole, and 3 is a brush to be planted in the planting hole 2.

The roller body 1 is made of wood, synthetic resin, etc. and has a round shaft. Appropriate intervals are provided on the outer periphery of the roller body 1 in the axial direction and the circumferential direction. A planting hole 2 is formed at an angle of a predetermined angle, and a brush 3 is fitted into the planting hole 2 and fixed thereto, and is projected out of the roller body 1 to an appropriate length.

The depth of the planting hole 2 drilled in the roller body 1 is approximately 1/2 of the length of the brush protruding from the roller body 1, so that the brush 3 to be planted can be rested against the cover. Make sure that elasticity is exerted to push out the conveyed object.

The brush 3 can be inserted into and fixed in the planting hole 2 formed at an angle in the roller body 1 by inserting the brush 3 into the planting hole 2 and pouring an adhesive 4 into the planting hole 2 to fix it ( (Fig. 2), the brush 3 is fixed in advance to a T-shaped substrate 5 with adhesive 4 in an upright state, and this is fitted and fixed into the planting hole 2 of the roller body 1 (Fig. 3).
(Fig. 4), or a configuration in which a brush 3' having a length twice the required length is folded in half into a U-shape, which is fitted into the planting hole 2 and fixed with a stopper 6 (Fig. 4), etc. , either is fine.

The brushes 3, 3' are made of an elastic resin material or other brush material, and are made by bundling a required number of thin brush base materials to a predetermined thickness.

Further, the manner in which the planting hole 2 in which the brushes 3, 3' are installed is not limited to the manner in which it is tilted in both the axial direction and the circumferential direction as shown in FIGS. As shown in FIG. 6, the roller body 1 is inclined at a predetermined angle in one direction along the axis O, or as shown in FIGS. 6a and 6b, the roller body 1 is inclined at a predetermined angle in the circumferential direction. But it's a good one.

(Effects of the Invention) The method for manufacturing a rotating transport roller of the present invention includes a first step of drilling planting holes in an arbitrary diagonal direction at appropriate intervals on the surface of the roller body, and a brush is inserted into the planting holes. The second step is to insert the material into the roller body and project it diagonally by a desired length from the surface of the roller body, so it exerts elasticity to push out the conveyed object in the direction of the axis of the roller. The tilted planting of the brush can be ensured and easily carried out.

Moreover, since the brush is planted by inserting and fixing a straight brush into a planting hole drilled at an angle, the planting work is very easy and no different from conventional methods. A more stable tilted implantation state can be established compared to a method in which the tip of the brush is laid down using heat pressure or the like.
