A method is used in which the used dirty mats are collected by a trader, washed and regenerated, and then loaned again to users.

Conventionally, a rotary drum washer has been used for cleaning rental shoe wiping mats. After a predetermined amount of mat is put in, a cleaning liquid is injected, and cleaning is performed under rotation, and spin dehydration, Batch cleaning is performed by performing rinse cleaning and rotary dehydration a predetermined number of times. However, in such a batch-type cleaning operation, since the matte pile that has been cleaned is brought into contact with cleaning waste liquid, there is a problem that recontamination occurs, and a large amount of water is used.
Further, since the mat is randomly and vigorously stirred and rotated in the washer, there is a drawback that the mat is easily damaged.

There have been many proposals for continuous washing of mats, and the continuous washing consists of a series of steps in which the mat is continuously conveyed to remove dust from the mat pile, and to wash and rinse the pile ( JP-A-50-1008
No. 56), dust removal of matte piles using a brush roll or vibration or vacuum, and cleaning using a brush roll or a combination of jet and vacuum.

There are various kinds of mat conveying methods as well, in which the mat is conveyed horizontally while maintaining a flat state (Japanese Patent Publication No. 4-48874 and Japanese Utility Model Publication No. 3-43392).
There is also known an apparatus in which a substantially vertical reversing conveyance section is provided between the upper horizontal conveyance section of the pile-down and the lower horizontal conveyance section of the pile-up (Japanese Patent Publication No. 56-4677).

[0006]

The conventional continuous cleaning method is somewhat satisfactory in that the treatment is carried out continuously, but it is still sufficiently satisfactory in terms of completeness of cleaning and saving of water used for cleaning. It wasn't possible.
Further, there is a problem in that the apparatus becomes extremely large in size when it is attempted to completely clean a mat such as a shoe-wiping mat that is extremely dirty.

[0007] Therefore, an object of the present invention is to provide a method which enables efficient and continuous cleaning while saving the amount of water used in a compact device without increasing the size of the device.

Another object of the present invention is to provide a continuous cleaning method for mats in which each processing area and the transportation method are efficiently and organically related.

A rubber backing layer is provided on the back surface. Depending on how the backing layer is provided, it is roughly divided into two types, a thin backing layer is provided, and when used, it is used in combination with a thick rubber base, and a separate type that only the upper part is collected and washed and regenerated, There is an integrated type in which a thick backing layer of a rubber sheet is provided. In addition, there are various types of mat piles, including hydrophilic fibers such as cotton fibers, polyvinyl alcohol fibers or recycled fibers, and hydrophobic fibers such as nylon, as well as uncrimped or crimped fibers. There are those that have been crimped, those that have cut piles and those that have loop piles. According to the continuous mat cleaning method of the present invention, reliable cleaning can be performed even if these various kinds of mats are randomly mixed and supplied.

First, in the present invention, the mat to be cleaned is supplied from the mat supply section 5 of the lower horizontal transport section 1. The mat may be supplied manually or automatically from a stack of mats. Generally, mats may be supplied so that the front and rear mats do not overlap.

The wet main cleaning by rubbing is performed in multiple stages. Dirt adhering to the pile pile on the mat pile surface is easily removed from the pile by the penetration and swelling action by the cleaning liquid and the sliding scraping action by the roller brush, and the dirty cleaning liquid is removed from the pile by gravity. The piles are separated so that they do not recontaminate the pile.

The radius of curvature of the curved portion of the mat in the main cleaning region is preferably about 20 mm to 40 mm. The rubbing direction between the mat pile surface and the roller brush is preferably forward with respect to the conveying direction. Generally, a suitable rubbing speed is about 2.5 to 5 m / sec.

As the cleaning liquid, any cleaning liquid used for cleaning this type of mat can be used. Generally, an aqueous solution containing a surfactant and a builder, particularly 5 to 40% by weight of a surfactant and a builder. An aqueous solution containing 60 to 95% by weight is used. However, when cleaning is performed in multiple stages, it is possible to change the composition of the cleaning liquid in each stage. For example, it is possible to use a concentrated cleaning liquid at the beginning and a thin cleaning liquid at the final stage. . The temperature of the cleaning solution is generally in the range of 40 to 60 ° C.

The amount of the cleaning liquid used is 0.8 to 1.5 liter per unit area (1 m ² ) and 4.0 to 6.0 liter in total, which is more than that of the conventional method. ,
It is an advantage of the present invention that even significantly soiled mats can be thoroughly cleaned with significantly less water. It is also an advantage of the present invention that the amount of the cleaning liquid used in each stage can be adjusted freely, and the amount used in each stage can be made equal or the amount used can be reduced toward the final stage. Further, it is possible that the cleaning liquid with less contamination at the final stage can be circulated and reused as the first cleaning liquid.

The mat after the main washing of the mat pile surface is inverted from the pile-down state to the pile-up state via the folding and reversing section 4b, and the upper horizontal conveying section 3 is formed.
Supply to.

The first mangle rollers 65 and 66 are arranged on the introduction side of the upper horizontal transport section 3 to pressurize and drain the cleaning liquid contained in the mat pile surface. The amount of rinse water used can be reduced by draining the liquid prior to the rinse. The degree of pressure applied by the mangle rollers 65 and 66 is generally in the range of 10 to 20 kg / m in linear pressure.

Next, the rinse unit 1 of the upper horizontal transport unit 3
2, a curved curved portion of the mat is formed by the bending roller 67, and rinsing water is sprayed on this portion and the opened pile and the roller brush 68 are rubbed against each other to perform wet rinse cleaning.

The radius of curvature of the curved surface of the mat in the rinsing / washing section 12 is generally preferably about 20 mm to 40 mm. The rubbing direction between the mat pile surface and the roller brush is preferably forward with respect to the conveying direction. Generally, a suitable rubbing speed is about 2.5 to 5.0 m / sec.

The amount of rinsing water used is a unit area (1 m ² )
Per stage, 1.5 to 3.0l, total 3.0
As compared with the conventional method, the mat can be completely rinsed with a remarkably small amount of water.

The mangle roller 6 is attached to the second pressurizing and liquid removing section 10.
5, 66 are arranged, and the rinse liquid contained in the mat pile surface is drained under pressure. The degree of pressure applied by the mangle rollers 65 and 66 is generally 10 to 20 kg / m in linear pressure.
It is suitable to be in the range of.

Finally, the mat pile surface, which has been dehydrated by the second mangle roller, is vacuum dehydrated by the vacuum dehydration mechanism 75. The degree of vacuum is 1200 to 1400 mm
Ag (absolute pressure) is suitable.

Performing the pressure dehydration and the vacuum dehydration in this order in combination has an advantage in efficiently performing the dehydration and reducing the load of the drying. That is, pressure dehydration is effective in squeezing out water between piles, while vacuum dehydration is effective in removing water retained on the pile yarn surface.

The washed mat is sent to a post-treatment process such as drying to be a washed and regenerated mat.
