Abstract

PURPOSE: To remove dust on shoes accurately by a method wherein shoes are put on a shoes mount and air is blown to the shoes from a nozzle part to remove dust while removing the dust on the soles of the shoes with a brush body and the removed dust is discharged from an air discharge part. CONSTITUTION: This dust removing apparatus is set, for example, on a floor surface or the like of an air shower chamber provided at an entrance of a clean room. When shoes of a worker are put on a shoes mount 22 through opening parts 12 and 12, sensor light of a sensor 36 is intercepted to start the supply or discharge of air automatically while a motor 33 is driven to rotate all brush bodies 25. Clean air is blown to the shoes from nozzles through an air supply path of a nozzle part 15 to remove dust on the shoes. At the same time, the dust on the soles of the shoes is removed with the brush bodies 25 rotating and the removed dust is discharged together with the air from the bottom part of the opening parts 12.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust removing device for removing dust adhering to shoes.

[0002]

2. Description of the Related Art Conventionally, for example, when a worker enters a clean room, dust-free clothes are worn and an air shower room provided at the entrance of the clean room removes dust. To prevent intrusion.

In the air shower room, clean air is blown to the whole body of a worker wearing dust-free clothes,
Dust adhering to the surface of dust-free clothes is separated, and the separated dust is exhausted together with air.

[0004]

However, dust adheres to the sole of the shoe before the worker wearing the dust-free clothes walks to the air shower room. The dust attached to the bottom of the shoe is the air shower. There is a problem that the air cannot be reliably removed only by blowing air in the room.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a dust removing device capable of reliably removing dust adhering to shoes.

[0006]

DISCLOSURE OF THE INVENTION A dust removing device of the present invention comprises a shoe rest portion having an opening vertically inserted, a nozzle portion for blowing air from the periphery of the shoe rest portion toward the center, and the shoe. An exhaust part that exhausts air from the bottom of the mounting part,
A brush body is provided below the shoe rest, and a part of the periphery of the shoe rest projects upward through the opening of the shoe rest and rotates.

[0007]

In the dust remover of the present invention, with the shoe placed on the shoe rest, air is blown from the nozzle toward the shoe to remove dust, and the brush rubs the bottom of the shoe to remove dust. The exhausted dust together with the air from the exhaust.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of an embodiment of the dust removing device of the present invention will be described below with reference to the drawings.

In the figure, 11 is a box-shaped main body frame, and a pair of left and right openings 12 are formed in the main body frame 11 so as to penetrate through the upper and lower surfaces. The opening 12 is longer than the length and width of the shoe, is wide, and is formed in a substantially rectangular shape into which the shoe can be inserted. Below each opening 12, a support frame 13 that constitutes a lower region of the opening 12 is provided, and a bottom plate 14 is attached by closing the bottom of the support frame 13.

Nozzles 15 are formed on the upper surface of the body frame 11 along the peripheries of the openings 12. This nozzle part 15
Has a hollow nozzle frame 17 in which an air supply passage 16 is provided, and a plurality of nozzles 18 for blowing air toward the center are formed on the inner surface of the nozzle frame 17 facing the opening 12. At the side of the main body frame 11, a blower unit 19 connected to the air supply passage 16 through a duct not shown, and a duct 20 at the bottom of the opening 12.
An exhaust unit 21 is provided that is connected via. The blower unit 19 is connected to an air supply device (not shown) that supplies clean air, and the exhaust unit 21 is connected to an exhaust device (not shown) that exhausts air.

A shoe rest 22 is provided in each opening 12. The shoe rest 22 has a pair of placing plates 23 provided on the upper end of the support frame 13 along the longitudinal direction.
Several 23 points are supported by stays 24 that are laid across the width of the support frame 13. The shoe rest 22 can be placed on the pair of placing plates 23 with shoes, and the opening 22a is formed in most of the portions other than the placing plate 23 and the stay 24.

Below the shoe rest 22, three brushes 25 are arranged in the longitudinal direction of each opening 12. Brush body
The wire 25 is composed of a wire brush in which the wires 27 are projected radially around the rotation shaft 26, and the peripheral surface formed by the tips of the wires 27 is formed into a cylindrical shape. Both ends of the rotary shaft 26 of each brush body 25 penetrate through both side walls of the support frame 13 and are rotatably supported by bearings 28, and the height of the upper portion of the wire 27 slightly protrudes upward through the opening of the shoe rest 22. It is supported.

Each brush body 25 is configured to integrally rotate by an interlocking mechanism 29. In this interlocking mechanism 29, the inner ends of the rotary shafts 26 of the brush bodies 25 facing left and right are integrally connected by a helical coupling 30, and the sprocket 31 is attached to the outer ends of the rotary shafts 26, and the right front Sprocket 31 of brush body 25 and sprocket 3 of brush body 25 in the middle right
1. Chains 32 are stretched around the sprocket 31 of the brush body 25 in the middle of the left and the sprocket 31 of the brush body 25 in the rear left.

A motor 33 is arranged in the left front portion of the main body frame 11, and a sprocket 34 attached to the drive shaft of the motor 33 and a sprocket 31 attached to the outer end of the rotary shaft 26 of the front left brush body 25. A chain 35 is stretched over.

Sensors 36 for projecting and receiving sensor light on the opening 12 are attached to the left and right sides of the upper surface of the body frame 11, and
A storage part 37 for the electric components is arranged in the front right of the inside of 11.

Next, the operation of this embodiment will be described.

The dust removing apparatus of this embodiment is installed, for example, on the floor surface of an air shower room provided at the entrance of a clean room or the floor surface of the entrance of an air shower room.

When a worker enters a clean room, at the entrance of the air shower room, the worker wearing dust-free clothes puts each shoe of both feet into each opening 12 and It is placed on the placing part 22.

As a result, the sensor can be worn by shoes or dust-free clothing.
In order to block the 36 sensor light, the dust removal operation is automatically started, air supply and exhaust are started, and the motor
33 is driven to rotate all brush bodies 25.

Then, clean air is supplied from the air supply unit to the blower unit 19, and air is blown from each nozzle 18 toward the shoe through the air supply passage 16 of the nozzle unit 15 to remove dust adhering to the shoe. . At the same time, the rotating brush body
Rub the bottom of the shoe with 25 to remove dust adhering to the sole. The removed dust is exhausted together with air from the bottom of the opening 12.

A predetermined time after the detection by the sensor 36, or when an operator pulls out the shoes of both feet from the opening 12 and the sensor 36
After the sensor light of returns to the light emitting / receiving state, or when the amount of dust contained in exhaust gas is detected and the amount of dust falls below a specified value, the dust removal operation is automatically stopped to supply and exhaust air. And the motor 33 are stopped.

In this way, the blowing of air and the brush body 25
Due to the synergistic effect of the above, it is possible to surely remove the dust attached to the bottom surface as well as the surface of the shoe.

[0023]

According to the dust removing device of the present invention, with the shoe placed on the shoe rest, air is blown from the nozzle toward the shoe to remove dust, and the brush rubs the bottom of the shoe. The dust that has been removed is exhausted together with the air from the exhaust section so that the dust that has adhered to the shoes can be reliably removed.
