JPS5892812A - Detector for time point of press-contact of brush roll - Google Patents

Abstract

PURPOSE:To detect the time point of contact of a brush roll to adjust the degree of rolling reduction of the worn brush to an optimum value, by forming the outmost brush hair of the brush roll with a very narrow copper wire and flowing a prescribed current when the brush is brought into contact with a work roll. CONSTITUTION:In respect to an outmost brush hair 1' of a brush roll, a very narrow copper wire is wound around a disc 2' consisting of an electric insulator to form a conductor narrow wire 4. Ring-shaped conductive plates 7 and 8 are mounted on a flange 5 and are connected by a conductive wire 9. In case of polishing of a work roll 15, when a conductor head 12 is brought into contact with the conductive plate 7 and the brush roll is brought into contact with the roll 15, a current is flowed from a prescribed power source to a control box 14, conductive plates 7 and 8, the brush hair 1', and the roll 15 and the detected by the control box 14. Thus, the time point of contact of a brush 1 is detected, and the degree of rolling reduction of the worn brush is adjusted to an optimum value.

Description

[Detailed description of the invention] A large number of disks with brushes attached around the object are arranged and inserted into a mandrel to form a rolled brush, and its 6 axes are installed on the original body and rotated, and the brushes are attached to a metal plate. Equipment for polishing and cleaning the material by pressing it against the material is already in general use. In this sharpening work, it is better to avoid point contact between the brush tip and the Kanasu plate.
Polishing is more effective when the bristles are brought into contact and the width of contact is increased.

In this case, although the working efficiency of the blade with a large contact width is good, the abrasion of the surface system is severe.Therefore, it is necessary to increase the polishing efficiency by appropriately setting the contact degree of the bristles to A#, and to avoid abrasion of the bristles as much as possible. No.

As the work continues, the tips of the brushes inevitably wear out gradually, so it is necessary to press the roll down from time to time to press the tips of the brushes against the plate surface and adjust the brush tips to maintain proper surface contact. When the brush is new, you can tell how many millimeters the roll should be lowered by judging from its maximum length, but if the bristles are worn, you don't know the exact length, so you have to figure out the reference point to determine how many millimeters you should lower it. No. The present invention has been devised for this purpose, and it is possible to lower the worn brush and detect at once the moment when it contacts the work roll, and then adjust the degree of compression of the brush to 14 teeth. This is a device that has

Out of the parallel brushes 1 of the constituent brush roll, the outermost brush 1' is wrapped with a conductor phase wire 4 such as an ultra-fine steel wire in a spiral manner or covered in a braided manner, and the brush roll is The disk 2' is made of an electrical insulator.

A woven electrical insulator 6 is placed around the french 5 of the mandrel 8, and #1 lead wires 7 and 8, such as copper plates, are attached to the outer and inner surfaces of the mirror to expose the surface. ft1i114
An air cylinder 10 is connected with a conductive wire 9 such as a wire, and an air cylinder 10 is placed at a position facing the conductive plate 7 on the outer surface, and an electric conductor head is attached to the head end of the piston rod 11 to be in contact with the outer conductive plate 7 at any time. 12 is connected to the head, and nine flexible electric wires 18 are connected to the control box 14 for inspection via a power supply, and the box, the original frame, and the work roll 15 are electrically connected by the conductor 16.

Effect: When the air cylinder 10 is actuated to cause the piston rod lit to protrude, the head 12 at its head end comes into contact with the outer conductive plate 7. Next, when the brush roll is lowered, the moment the tip of the brush 1 touches the work roll 15, the power supply and control box 14. Flexible electric wire 1B, head 12. Outer and inner conductive plates 7, 8. By observing the number control box 14 where electricity is passed through the outermost brush 1' and the work roll 159 body, the point at which the brush tip contacts the work roll 15 can be determined (Fig. 2). All you have to do is measure from that point and reduce the appropriate amount of hair.

In this way, according to the present device, the brush can be accurately and quickly adjusted downward, thereby improving the efficiency of the polishing work.
