Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a sheet cleaner. More specifically, it relates to a sheet cleaner used for cleaning and drying a contaminated plastic sheet pallet.

[0002]

2. Description of the Related Art Conventionally, various improvements have been attempted in order to improve the efficiency of freight transportation, and as one of them, there has been proposed a method of carrying a cargo on a seat and carrying it out by a forklift, transporting and storing the cargo. ing. For example, in FIG.
As shown in (a), a grip portion 2 is provided on a flexible synthetic resin sheet 1 having a thickness of about 2 mm, and a load is placed on a loading surface.
A sheet pallet 4 that has been embossed 3 and roughened so that the load can be moved smoothly without hitting the entire surface.
As shown in FIG. 6 (b), there is a method of using a push-pull pull forklift 5 to lift the load 6 onto a fork 7 or push it out of the fork for transportation and storage.

The sheet pallet used for transportation and storage as described above is contaminated by the adhesion of mud, fats and oils during use. In such a case, it is necessary to wash the sheet pallet, but in the conventional washing method, a person manually washed one by one with a deck brush or the like, and wiped the remaining moisture with a waste cloth or a cloth. .

[0004]

However, the conventional manual sheet pallet cleaning method has a problem in that the operator is burdened with a large amount of cleaning work and the work efficiency is low.

In view of the above-mentioned conventional problems, the present invention aims to realize a small-sized and portable sheet cleaner capable of automatically performing cleaning and drying on both sides of a plastic sheet pallet.

[0006]

The sheet cleaner of the present invention is an apparatus for cleaning, dehydrating and drying a sheet pallet, which comprises a roll for feeding a sheet, a spray nozzle for ejecting a cleaning liquid, and a sheet pallet. A cleaning process part consisting of a brush roll for cleaning, a porous water absorbing roll for the purpose of dehydration and drying, and an air nozzle for blowing warm air to remove the cleaning liquid remaining on the embossed surface of the sheet pallet and drying it. And a dehydration / drying process part consisting of a combination of.

In addition to the above, the cleaning step portion is characterized in that a sheet feeding roll and a brush roll are arranged so that the sheet pallet to be cleaned can be curved in a concave shape. In addition to the above, the washing step portion and the dehydration / drying step portion are characterized in that they are arranged on the upper surface of a box-shaped carriage having casters at the bottom.

By adopting this construction, it is possible to obtain a small-sized, portable sheet cleaner capable of automatically performing cleaning to drying on both sides of the plastic sheet pallet.

[0009]

The sheet pallet sent from the sheet feed roll is curved in a concave shape by the sheet feed roll, the sheet guide and the brush roll, so that the cleaning liquid collects on the upper surface and the cleaning with the brush roll becomes good, The embossed depressions on the surface of the sheet are washed. In the dehydration / drying process, the cleaning liquid on the surface is removed by the squeeze roll, the cleaning liquid remaining in the recesses on the embossed surface is blown away by the warm air blown from the air nozzle, and finally completely removed by the water absorbing roll.
