Description

  The present invention relates to a sheet-like cleaning apparatus that cleans a sheet-like material between a pair of upper and lower cleaning brushes.

  Conventionally, as this type, the sheet body is sandwiched between the upper sandwiching roller and the lower sandwiching roller, washed with the upper cleaning roller and the lower cleaning roller, and then the sheet body is sandwiched with the upper and lower sandwiching rollers, and the feeding process is continuously performed There are devices to perform (for example, Patent Document 1 and Patent Document 2).

  In the above apparatus, cleaning liquid is circulated and cleaning is performed by a roller. In this method, dirt dropped from the sheet-like material adheres to the roller side, and this dirt may adhere to the sheet-like material again. In such a case, a rinsing step with a cleaning solution or the like is necessary, which is very laborious. Furthermore, the conventional apparatus cannot obtain a sufficient cleaning effect against dirt such as highly viscous grease.

  Moreover, in the cleaning apparatus provided with the cleaning brush, as in Patent Documents 1 and 2, the roller rotates in the direction of feeding the sheet-like material. In this case, the rotation of the cleaning brush is set faster than that of the transport roller, and the cleaning brush forcibly sends the sheet-like material, causing a transport failure or leaving a washing residue. It was the cause.

  By the way, there is a so-called industrial rewritable sheet (reversible heat-sensitive storage member) which is a sheet-like material of a reversible heat-sensitive storage medium. The sheet-like material is made of a resin or the like, and has a heat-sensitive layer and a protective layer on a support. It is possible to repeatedly write character information and the like by heat, and furthermore, various information can be stored by attaching an IC tag (for example, Patent Document 3 and Patent Document 4).

  The industrial rewritable sheet as described above is suitable for processing instructions in factories and the like, and is used repeatedly. Under such use conditions involving on-site work, dirt such as oil tends to adhere to the sheet-like material. For this reason, it is necessary to wash before rewriting the contents during repeated use.

However, as described above, conventional cleaning apparatuses have poor oil removal efficiency. In addition, in the conventional apparatus, since the rotation direction of the cleaning brush is the same as the conveyance direction, when an IC tag is attached to the edge of the sheet-like material or the sheet-like material, the edge portion or its bonding step Dirt was easy to remain on the part.

  In the cleaning of the cleaning rollers 7, 7A, 8, 8A, the cleaning liquid 46 is sprayed from the supply hole 42 of the rotating shaft 21 by driving of the liquid feeding devices 44, 44A, and this cleaning liquid 46 cleaned the sheet-like object 101. Thereafter, it falls into the lower cleaning liquid tank 45, and the contaminated dirt is removed by the filter means 48, and it is repeatedly circulated for use.

  Further, as described above, the first lower cleaning roller 7A is in contact with the sheet-like material 101 with the brush wire 22 in the direction opposite to the feeding direction, but on the conveying side of the cleaning roller 7A, the guide plate 26A is provided. Since the front end sides are provided close to each other, the sheet-like object 101 can be smoothly fed together with the feeding of the feeding rollers 6 and 6A. Further, the second upper cleaning roller 8 abuts the brush wire 22A against the sheet-like object 101 in the direction opposite to the feeding direction, but between the guide plate 26 and the guide plate 26B above the conveyance path 5. Since the plurality of guide rods 31 are arranged, the upper surface (front surface) of the sheet-like object 101 can be guided by the guide rods 31 and smoothly sent out to the guide path 29.

  Thus, in this embodiment, corresponding to claim 1, the pair of rotary cleaning brushes 7, 7A, 8, 8A is provided, and the cleaning liquid 46 passes between the pair of cleaning brushes 7, 7A, 8, 8A. In the apparatus for cleaning the sheet-like object 101, the pair of cleaning brushes 7 and 7A rotating in the same direction and the pair of cleaning brushes 8 and 8A rotating in the opposite direction are provided. Thus, when the pair of cleaning brushes 7, 7A, 8, and 8A rotate in the same direction, the brush wire 22 hits one of the front and back sides of the sheet-like object 101 in the transport direction and the other reverse to the transport direction. The brush wire 22 hits in the direction, and in the other pair of cleaning brushes 8 and 8A, one of the front and back sides of the sheet-like object 101 hits the brush wire 22A in the direction opposite to the conveyance direction, and the other is conveyed Brush wire 22A hits in the direction Thus, in combination with the effect of the cleaning liquid 46, dirt such as the edge of the sheet-like material 101 can be effectively removed. For example, even if there is a stepped portion on the surface, dirt around the edge can be scraped off.

  In this way, in this embodiment, corresponding to claim 2, the cleaning brushes 7, 7A, 8, 8A have the brush wire materials 22, 22A provided radially, and the cleaning brushes 7, 7A adjacent to each other are cleaned. Since the groups of brush wires 22 and 22A of the brushes 8 and 8A are different, the contact state is different with respect to the sheet-like object 101, and the dirt can be scraped off with different scraping forces.

  As described above, in this embodiment, the diameters of the brush wires 22 and 22A are different from each other in correspondence with the third aspect. Therefore, the brush wire 22 having a small diameter becomes a relatively soft brush and the brush wire 22A is thick. The thing becomes a comparatively hard brush. For example, the soft cleaning brushes 7 and 7A are used to scrape off the dirt so that the cleaning liquid 46 becomes familiar with the dirt, and the remaining dirt is scraped off by the hard cleaning brushes 8 and 8A. Can do.

  As described above, in this embodiment, since the supply hole 42 serving as the cleaning liquid supply unit is provided in the cleaning brushes 7, 7A, 8, 8A correspondingly to the fourth aspect, the cleaning brushes 7, 7A, 8, 8A Then, the cleaning liquid 46 is supplied uniformly to the brushes 7, 7 A, 8, and 8 A, and the sheet 101 can be effectively cleaned with the cleaning liquid 46.
