Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wallpaper pasting machine that continuously applies glue to the back surface of a long wall covering when, for example, a sheet-like wall covering is applied to an indoor wall surface, and in particular, an end of the wall covering. The present invention relates to a supply means for supplying a tape to be attached to a section.
[0002]
[Prior art]
A conventional wallpaper pasting machine uses a plurality of rolls built in the pasting machine body to draw a long sheet-like wall covering from the back of the main body and pull it from the front to the back of the wall covering. The wall covering material is cut in the width direction by a cutting means such as a cutter at a predetermined position. When continuously pasting the wall coverings glued using such a wallpaper pasting machine in the vertical direction of the wall surface (the direction from the upper surface of the wall to the lower surface of the wall or vice versa) An operation is performed for each sheet in which an operator applies a plurality of wall coverings glued by a wallpaper pasting machine to a predetermined position on a wall surface.
[0003]
[Problems to be solved by the invention]
However, when the wall covering material pasted by such a conventional wallpaper pasting machine is stuck on the wall surface in the vertical direction, the operator does not create a gap between the wall covering materials stuck on the wall surface. However, there is a problem that a great deal of labor is required for wallpaper pasting work because it is necessary to stick the wall covering material so that the position of the wall covering does not shift.
[0004]
In addition, after the two glued wall coverings are stacked on top and bottom and attached to the wall, the upper wall covering is cut along the side of the lower wall covering overlapped by a cutter. However, if the cut end portion of the upper wall covering material is removed, a gap is hardly generated between the attached wall covering materials, which is convenient.
[0005]
However, in this case, there is a problem in that the glue applied to the back surface of the removed upper wall covering end portion adheres to the surface of the overlapped lower wall covering end portion.
[0006]
The present invention has been made in view of such problems, and simplifies continuous wallpaper pasting work in the vertical direction of the wall surface to reduce the labor of the operator, and the wall covering material after pasting The main object is to provide a wallpaper pasting machine in which no glue remains on the surface. Another object of the present invention is to provide a wallpaper pasting machine capable of accurately cutting a wall covering material affixed to a wall surface.

[Means for Solving the Problems]
In order to achieve the above-mentioned object, the invention according to claim 1 is characterized in that the sheet-like wall covering is applied to the back surface of the wall covering while the sheet-shaped wall covering is pulled out from the rear and pulled out from the front. In the machine, the tape supply means for supplying the tape to be applied in the width direction of the back surface of the wall covering material, arranged at a position where the wall covering material after the glue application is pulled out from the pasting machine main body ,
A guide portion for guiding the tape supplied from the tape supply means,
The guide part has a U-shaped cross section with a groove formed by a protrusion part protruding forward and an upper and lower protrusion part in both the upper part and the lower part, and the width of the groove is substantially equal to the width of the tape, The upper and lower protrusions indicate the cutting positions in the wall covering width direction at the upper and lower portions of the tape .
[0008]
In the tape supply means of the present invention, the “width direction of the back surface of the wall covering material” means a direction perpendicular to the conveying direction of the wall covering material and corresponds to the cutting direction of the wall covering material. In addition, the “position where the wall covering material after the glue application is pulled out from the main body of the gluing machine” is the rear position of the main body of the gluing machine and the position where the wall covering material to which the glue is applied by the main body of the gluing machine is carried Specifically, in addition to the position of the front end portion of the wall covering material to be carried out, the position where the wall covering material already carried out is to be cut (that is, the position that becomes the rear end portion of the cut wall covering material) is included.
As described above, since the tape supply means for supplying the tape to be applied in the width direction on the back surface of the wall covering material is arranged at a position where the wall covering material after applying the glue is pulled out from the main body of the pasting machine. A tape will be affixed to the back surface of the edge part of the wall covering pulled out from the main body. Glue has already been applied to the back of the wall covering pulled out from the gluing machine main body, and the tape is supplied and pasted to the back of the adhesive after applying the glue. Even when they are combined, the glue on the back surface of the upper wall covering does not adhere to the surface of the end of the lower wall covering. For this reason, after overlapping the top and bottom and sticking to the wall surface, cut the upper wall covering along the side of the lower wall covering overlapped by the cutter, and cut the upper wall covering When the portion is removed, no glue remains on the surface of the wall covering material, and the wall covering material can be attached without any gaps, so that the labor of the wallpaper attaching operation is reduced.
[0009]
The tape supply means of the present invention is particularly configured as long as the wall covering material after applying glue is arranged at a position where it is pulled out from the main body of the pasting machine and supplies a tape to be applied in the width direction of the back surface of the wall covering material. It is not limited. As such a tape supply means, the tape is held in advance at the position where the wall covering material is pulled out, and the operator manually introduces the tape into the predetermined position. You may comprise so that it may introduce. In this case, there is an advantage that the labor of the operator is reduced.
[0010]
The tape supply means can be provided with a tension holding means for holding the tension of the supplied tape constant. In this case, the tape can be uniformly adhered to the wall covering material by preventing the tape from bending. As such a tension holding means, any means capable of removing the bending of the tape in the width direction of the wall covering material may be used, for example, a bar that pulls the end of the tape when the tape is supplied to the wall covering material. Can be mentioned.
[0011]
The wallpaper gluing machine of the present invention is not only an automatic wallpaper gluing machine that glues while automatically conveying wall covering, but also a manual wallpaper gluing machine that manually conveys and glues wall covering. included.
[0013]
