Description

  The present invention relates to a building floor sheet laying device used for installing a dustproof adhesive sheet at an entrance of a building or the like.

  Conventionally, dust-proof adhesive sheets have been installed at the entrances of spaces where entry of dust and dust from the outside, such as semiconductor-related factories and chemical factories, has been a problem, and dust and dirt adhered to footwear has been removed. It has been broken.

Such a dustproof pressure-sensitive adhesive sheet is formed by, for example, laminating a plurality of pressure-sensitive adhesive films, and adsorbing power is reduced so that dust and dust can be adsorbed and removed from the pressure-sensitive adhesive layer and the dustproof ability can be maintained. It is considered to install the adhesive films so that they can be peeled off sequentially. (For example, see Patent Document 1.)
Japanese Patent Laid-Open No. 10-151103

  However, if the dust-proof adhesive sheet is installed at the entrance through which the forklift and the transport vehicle pass, the dust-proof adhesive sheet may be damaged. At this time, not only the dust-proof adhesive sheet exposed on the surface but also several sheets immediately below it are often damaged at the same time, that is, wasteful removal of unused adhesive sheets is caused.

  In addition, there is a demand for more effective dust prevention by installing such dustproof adhesive sheets not only near the entrance of spaces where entry of dust and dust from the outside is a problem, but also in the entire passageway leading to the entrance. However, when the configuration described in Patent Document 1 is adopted, it is necessary to spread the adhesive sheet bundle obtained by laminating a plurality of adhesive sheets in such a passage area, and the cost is increased. Is difficult.

  This invention solves such a subject, and it is comprised so that a dust-proof adhesive sheet can be installed in the entrance / exit which a forklift and a conveyance vehicle pass, and the channel | path area | region connected to this entrance / exit.

  That is, the building floor sheet laying apparatus according to the present invention is used for laying a sheet having an adhesive layer on both surfaces of a base material and provided with a peeling portion adjacent to at least one adhesive layer. A sheet holding unit that holds the sheet, a sheet pressing unit that presses any surface of the sheet fed from the sheet holding unit toward a building floor, and the peeling unit that is peeled from the sheet. It is characterized by comprising a peeling part winding part that winds up, and a running support part that supports the sheet holding part, the sheet pressing part, and the peeling part winding part so as to be able to run on the building floor.

  If it is such, while pressing the sheet | seat drawn | fed out from the said sheet | seat holding | maintenance part with the said sheet | seat press part, and crimping | bonding this sheet | seat to a building floor surface, the said peeling part peeled from the said sheet | seat is taken up the peeling part. Since the traveling support unit supports the sheet holding unit, the sheet pressing unit, and the peeling unit winding unit, the adhesive material layer can be applied to the sheet while traveling on the building floor. In the exposed state, it can be laid directly on the floor surface, so that laying work can be easily performed. And because it adopts a mode in which a single sheet is directly attached to the floor surface, unlike a mode in which a plurality of sheets are polymerized and laid, when such a sheet breaks, all the other sheets are damaged. Therefore, it is possible to reduce the running cost of a mode in which such a seat is laid in the entire passageway connected to the entrance through which the forklift and the transport vehicle pass. The phrase “can run on a building floor” is a concept including the ability to run on a sheet in a state where the sheet is laid on the building floor.

  If it has a sheet removal part that winds and removes the sheet peeled off from the building floor surface, it absorbs a lot of dust, dust, etc. Since laying can be performed at the same time, the time required for such sheet replacement can be shortened, and cost can be reduced in this respect as well. Further, since the removed sheet can be discarded in a wound state, the unnecessary sheet can be easily discarded.

  If the height position of the sheet pressing part is configured to be changeable, the thickness dimension can be changed by changing the height position of the sheet pressing part corresponding to the thickness dimension of the sheet to be laid. Can accommodate different sheets.

  If it is possible to change the surface of the sheet that faces the building floor surface, depending on the required adsorption performance, floor material, etc. The surface on which the adhesive material layer having a more appropriate adhesive force is formed can be pressure-bonded to the building floor surface.

  If the traveling support part includes a traveling roller that presses the sheet toward the building floor and rolls on the sheet at a position separated from the sheet pressing part, the traveling roller While pressing a sheet | seat and it can adhere | attach a sheet | seat on a building floor more reliably, since a driving | running | working roller plays a role as a wheel, driving | running | working of a sheet | seat laying apparatus can be stabilized.

  The sheet laying device for a building floor according to the present invention is a single sheet that is formed from a sheet holding unit by forming an adhesive layer on both sides of a base material, providing a peeling portion adjacent to one of the adhesive layers. While the sheet pressing part is pressed against the building floor surface by the sheet pressing part and directly crimped to the building floor surface, the peeling part peeled off from the sheet is wound up by the peeling part winding part, and the traveling support part Since the sheet holding portion, the sheet pressing portion, and the peeling portion winding portion are supported on the building floor or on the sheet laid on the building floor so as to be able to travel, the entrance through which the forklift and the transport vehicle pass In addition, the dustproof pressure-sensitive adhesive sheet can be easily and inexpensively installed in the entire passageway connected to the doorway.
