Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a cleaning device that automatically cleans carpets while moving them on a belt conveyor.

[Conventional technology]

A conventional carpet cleaning device has a polishing brush attached to a rotating shaft arranged transversely to the direction in which the carpet travels, and sprays cleaning liquid onto the carpet while rubbing the carpet with the outer periphery of the polishing brush.

In addition, a rotating plate is installed at the bottom of the vertical rotating shaft,
Some brushes have a plurality of rotating brushes attached to the rotary plate, but since there is only one rotary plate, there is a problem in that uneven cleaning tends to occur.

[The problem that the idea aims to solve]

In the conventional cleaning device as described above, a part of the cylindrical outer periphery of the polishing brush comes into line contact and rubs against the carpet, which tends to cause uneven cleaning. Furthermore, since conventional detergent solutions are used, water can penetrate to the base of the carpet. As a result, color bleeding or extreme shrinkage may occur, and the fabric may become stiff. Furthermore, it takes a long time to dry, and a large amount of cleaning agent is used. There are problems such as mold growth because moisture remains at the base.

The purpose of this invention is to solve the above-mentioned problems and provide a cleaning device that has various features such as uniform cleaning and quick drying.

[Means to solve the problem]

In order to achieve the above objective, this invention has multiple rotary plates that rotate about a vertical axis arranged in parallel horizontally on a conveyor belt for moving carpets to be cleaned, and the bottom of each rotary plate has a vertical A plurality of polishing brushes are rotatably attached to rotate around the tube axis of the conveyor belt to rub the carpets on the conveyor belt, and the polishing brushes on one of the adjacent rotating plates are connected between the polishing brushes on the other rotating plate. Driving means is provided to rotate each rotary plate synchronously so that the rotation direction of the adjacent rotary plate is opposite to the rotation direction of the adjacent rotary plate so that a part of the outer periphery enters, and the polishing brush attached to each rotary plate is attached to the adjacent rotary plate. A driving means for driving the attached brushes in the opposite direction of rotation is provided, and a foam cleaning liquid supply means is provided for spouting foam cleaning liquid from the cleaning liquid outlet at the lower end of each tube shaft, and A guard plate made of a perforated plate is provided between the cleaning carpet and each polishing brush.

[Effect]

This invention has the above-mentioned structure, and when the carpet to be cleaned is supplied onto the conveyor belt, the carpet is attached to the lower part of the plurality of rotating plates above and rotates around the circumferential orbit while moving together with the conveyor belt. Rubbed with a polisher brush.

At the same time, the foamy cleaning liquid containing air bubbles is jetted to the center of each polishing brush, so that the carpet can be efficiently cleaned.

A drive sprocket 26 driven by a motor (not shown) is engaged with a part of the chain 27.

Further, each vertical shaft 9 is spaced at such an interval that a part of the brush 18 on the other rotating plate 11 does not come into contact with the polishing brush 18 provided on one side of the adjacent rotating plate 11, as shown in FIG. do.

A groove pulley 29 is provided at the upper end of each vertical shaft 9.
is fixed, and the groove pulleys 31 of each motor 30 and the pulley 29, which are arranged in the frame 6 so as to correspond to each vertical axis 9, are interlocked by a transmission belt 32, and the connected pulleys 23 are alternately moved in opposite directions. Drive it.

At the center of the vertical shaft 9, a cleaning liquid supply path 33 is provided which reaches from the upper end to near the lower end as shown in FIG. The supply pipe 35 communicates with a cleaning liquid tank 37 via a valve 36 as shown in FIG.

At the bottom of the tank 37 is an air pipe 3 that leads to a compressed air source such as an air compressor or an air tank.

A plurality of communication holes 41 communicating with the supply path 33 to the outside are provided around the lower end of the vertical shaft 9, and a liquid-tight chamber 42 communicating with the communication holes 41 is provided inside the cylinder 10 by upper and lower mechanical seals. The upper end of the tube shaft 12 is communicated with the upper end of the tube shaft 12 through a flexible tube 43.
The lower shaft is opened to form a cleaning liquid spout 45.

In FIG. 1, reference numeral 46 indicates a rotating brush for dust removal, and 47 indicates a guide belt, which is supported in an inclined manner by upper and lower rollers 48, and below which a rotating brush 50 for hair styling is arranged, but these are known ones. It is driven in the direction of the arrow by an appropriate driving means.

51 is a fresh water tank, and 52 is a fresh water pump, which pumps water from the fresh water tank 51 to the shower device 53, and these are also known.

A receiving tray 54 is provided below the hair styling rotating brush 50, and a route conveyor 55 for carrying out the washed carpet is provided below the receiving tray 54.

Next, to explain the operation of the above embodiment, while the belt 1 is running in the direction of the arrow, the carpet 56 to be cleaned is passed from the left side of FIG. Send it between 17 and 17.

The fed carpet 56 is sent to the right in FIG. 1 while being rubbed by the polishing brush 18 rotating on the guard plate 17.

On the other hand, by opening the valve 39, compressed air from the compressed air source passes through the air pipe 38 to the cleaning liquid tank 37.
sent to.

The tank 37 already contains cleaning liquid mixed with detergent and water.
When compressed air enters 7, the air becomes bubbles and mixes with the cleaning liquid, and by opening the valve 36, the cleaning liquid containing bubbles flows from the supply pipe 35 to the running joint 34 to the supply path 33 to the communication hole 41. →Flexible tube 4
3 → tube axis 12 → and is ejected from the ejection port 45 at the lower end.

Further, each polisher brush 18 is connected to each motor 30.
The vertical shaft 9 is driven by the groove pulley 23, the belt 24, and the groove pulley 13 are driven to rotate, and the chain 2 is rotated by the drive sprocket 26.
7, each sprocket 25 rotates together with each rotating plate 11 in the direction of the arrow in FIG.

As shown by the arrows in FIG. 2, each rotating plate 11 is in a state in which adjacent ones rotate synchronously in opposite directions, and the brushes 18 of the other rotating plate 11 are slightly inserted between the polishing brushes 18 of one rotating plate 11. Since the carpet 56 rotates at a constant speed, the surface of the carpet 56 is constantly rubbed.

The carpet 56 that has passed through this area while being rubbed by the polisher brush 18 as described above is removed by the rotating brush 46 for removing dust, sent downward by the guide belt 47, and subjected to hair styling treatment by the rotating rotating brush 50 for hair styling. The lower unloading conveyor 55
It is ejected upward and sent out.

In addition, if fresh water treatment is required, the guide belt 4
7 and the brush 50, the shower device 53
moves forward and pumps fresh water from the pump 52 onto the carpet 5.
6 to wash away the cleaning liquid, and collect the cleaning water by vacuum suction.

[Effect of idea]

As mentioned above, this idea is based on a plurality of polishing brushes attached to a plurality of rotary plates arranged horizontally with respect to the direction of carpet movement. Since a part of the outer periphery of the polishing brush of the other rotating plate is inserted between the polishing brushes of the rotating plate, the surface of the carpet is thoroughly and evenly rubbed.

In addition, as mentioned above, as the numerous polishing brushes rub the carpet, a foamy cleaning solution containing countless air bubbles is released at the center of rotation of each brush, which prevents the wastage of detergent and ensures that the cleaning solution is distributed evenly. Since it is supplied to the carpet without any problem, uneven cleaning and streaks due to dirt do not occur.

Further, since a guard plate made of a perforated plate is provided between the carpet to be cleaned on the conveyor belt and each polishing brush, it is possible to prevent the carpet from being rolled up by the brush, and from being damaged by long hairs.
