Abstract

PURPOSE:To provide a new rotary brush automatically discharging the static electricity generated during polishing by resolving the defect that static electricity is generated when leather shoes are polished with a rotary brush before the shipping to the market and dirt is stuck to the commodity (shoes) via the static electricity. CONSTITUTION:Soft and conducting members 4 not damaging a commodity are provided in a fabric brush 1 or a hair brush. Static electricity is conducted to a drive shaft 6 by the conducting members 4 and discharged.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary brush having a structure for removing static electricity generated during polishing.

[0002]

2. Description of the Related Art The surface of a shoe or the like is polished with a rotating brush (cloth brush, bristle brush) when it is shipped to the market, but static electricity is generated due to friction of the product during polishing. Dust and the like once wiped off the surface adheres again, and in order to remove it, dust is removed by hand again with another brush or cloth.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a novel rotary brush which eliminates the above-mentioned conventional drawbacks by automatically discharging static electricity generated during polishing.

[0004]

[Means for Solving the Problems] In order to achieve the above object, one of the invention is to insert a plurality of cloth brushes on a metal shell and bond the cloth brushes to both ends of the shell. In a brush that is clamped and fixed by a collar, a plurality of conductive members having flexibility are attached to a disk member made of paper, cloth, or other soft material with an axial hole opened at the center, and the base end of which protrudes into the axial hole. The disk member is placed between the cloth brushes on the shell, the base end of the current-carrying member is brought into contact with the shell, and the tip end reaches at least the outer peripheral edge of the cloth brush. The other one is that a bristle brush is spirally wound on a wooden cylinder, the cylindrical body is inserted into a metal shell, and is clamped and fixed by a collar attached to both ends of the shell. In such a brush, a plurality of metal pieces are attached to the front and back of the wooden cylinder in the longitudinal direction. A structure in which a plurality of flexible current-carrying members are mounted on the tubular body and are wound in a U-shape so that the tip of the current-carrying members reaches at least the outer peripheral edge of the bristle brush. Is.

[0005]

In the present invention, therefore, in the case of the cloth brush, the disk members are staggered between the plurality of cloth brushes, and the base end portion of the current-carrying member protruding into the shaft hole of the disk member is the drive shaft. The static electricity generated when the product (for example, leather shoes) is brought into contact with the shell fitted to the disk is energized to the drive shaft by the energization member of each disk member and discharged.

Further, in the case of a bristle brush, in order to fix the bristle brush with an adhesive, a means for mounting the bristle brush on a wooden cylinder and fixing it on a metal shell is adopted. A plurality of metal pieces are attached across the front and back in the length direction of the cylinder, so that the current-carrying member wound around the cylinder always keeps contact with the metal pieces and keeps static electricity during polishing. Is a material that is energized from the metal piece to the shell and the drive shaft to be discharged.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in the drawings will be described below. Reference numeral 1 is a cloth brush, 2 is a disk member made of paper, and a shaft hole 3 is opened in the center thereof. Multiple current-carrying members (trade name, Thunder loan)
4 are arranged radially and adhered with an adhesive applied to the disk member 2 in advance, sandwiched between the two disk members 2, and the base end of the current-carrying member 4 is projected into the shaft hole 3. Reference numeral 5 is a metal shell fitted to the drive shaft 6, and the cloth brush 1 and the disk member 2 are alternately stacked and mounted on the shell 5, and the collars 5a are arranged at both ends to cloth cloth 1 The disk member 2 is sandwiched and fixed to the shell 5, and the tip of the current-carrying member 4 reaches at least the outer peripheral edge of the cloth brush 1.

Further, the bristle brush 7 is spirally wound around a wooden cylindrical body 8 and fixed with an adhesive, and the current-carrying member 4 is wound around the cylindrical body 8 in a U shape. The tip of 4 is set so as to reach at least the outer peripheral edge of the bristle brush, and a plurality of metal pieces 9 are attached to the front and back of the wooden tubular body 8 in the longitudinal direction. The body 8 is fitted on the shell 5 to be inserted into the drive shaft 6, and both ends thereof are clamped and fixed by the collars 5a. Moreover, even if the shell 5 is made of wood by removing the wooden tubular body 8, the metal piece 9 is mounted on the shell 5, and the bristle brush 7 and the current-carrying member 4 are mounted by the same method as above, the same result is obtained. Is what you get.

[0009]

As described above, according to the present invention, since the current-carrying member is interposed between the brushes, the static electricity generated between the brush and the product is energized and discharged to the drive shaft. There is no adhesion of dust due to static electricity to, and the polishing effect with a brush is fully exerted, and the dust wiping work after polishing as in the past is unnecessary, which is beneficial for product quality improvement and cost reduction by improving work efficiency. And so on.
