Description

  The present invention relates to a wallpaper pasting machine designed to be compact.

  Currently, affixing of wall coverings to interior walls in interior construction of buildings is performed while applying glue continuously to sheet-like wall coverings using a dedicated wallpaper pasting machine at the interior work site. It has become common. As a general configuration of this wallpaper gluing machine, a gluing machine main body mainly composed of an upper structure and a lower structure in which a plurality of rolls are arranged is placed on a pedestal supported by legs. The sheet-like wall covering material (hereinafter referred to as “cross”) sandwiched between the upper and lower structures is transported by a roll, and the glue is picked up from the glue tank by the glue scraping roll that is pivotally supported in the glue tank to be used as a glue roll. It is transferred and applied to the back of the cloth by this gluing roll.

  There are two types of wallpaper pasting machines: manual type and automatic type. As an example of the specific configuration, the upper structure is placed on the lower structure with a cloth fed from the roll roll placed on the front of the main body. Is closed and a cross is sandwiched between predetermined rolls of the lower structure and the upper structure. In the manual device, the operator holds the tip of the cloth by hand and pulls it forward to rotate a part of the roll while rotating the other roll in conjunction with the gear. In an automatic apparatus, the roll of a predetermined roll is generally connected to a drive source such as an electric motor and rotated to rotate the other rolls in conjunction with each other via a gear. In any of the pasting machines, the glue that has been pulled up and transferred from the inside of the glue tank in the middle of conveying the cloth from the rear side to the front side of the pasting machine main body by rotating the roll is transferred from the roll in the vicinity of the apex of the pasting roll. The glue is transferred to the back surface of the cloth, and the cloth is sent out from the front face with the glue applied.

  In such a wallpaper gluing machine, since the gluing machine main body composed of the upper structure and the lower structure and the pedestal portion provided with the legs are separable (for example, see Patent Document 1), If transport by casters is not possible, the gluing machine body and pedestal unit are integrated into the interior work site and carried by two or more workers with each of the left and right sides, or a gluing machine The main body and the pedestal are separated and carried by one or more workers.

JP 2005-342990 A

  In such a conventional wallpaper pasting machine, a slitter hook is hooked on the rear portion of the main body stay. For this reason, conventionally, the slitter has a shape that simply protrudes from the main body. When carrying it, especially when carrying it alone, the smaller depth is lighter, and it is easier to handle when turning a narrow staircase. In addition, if the depth is small, the installation space for the car can be small.

  In the wallpaper gluing machine, the effective gluing width is about 1050 mm, and the width of the rollers such as the gluing roller exceeds 1050 mm as the effective gluing width and includes the bearings and side walls at both ends. The overall width of the machine itself exceeded 1200 mm. As a result, the weight in the state in which the main body of the gluing machine and the pedestal unit are integrated is too wide for one operator to carry, and is too heavy for at least two people in consideration of safety. It was usual to do it by the worker.

  By the way, the effective width of the wall covering material circulated in the market is 960 mm, and it is general that the ears of about 10 to 20 mm at both ends are cut and glued with a width of 920 to 940 mm.

  In order to obtain a compact wallpaper pasting machine, the present applicant sets the effective width length of a plurality of rollers to 1000 cm or less and 920 mm or more, and suppresses the slitter unit from popping out of the pasting machine body. We are going to propose a new gluing machine that has a concave mounting part formed in the width direction of the main body on the rear surface of the attachment machine, and a shape in which the front part of the slitter part is inserted into this concave mounting part and can be attached. .

  However, since the slitter part is embedded in the gluing machine body, the tension is good when pulling the wall covering from the rear part of the gluing machine in the case of wall covering that has been rewound or whose ears have been crushed. I found a problem that didn't work. Therefore, the present invention can be used even when the wall covering material is drawn into the slitter unit and the main body of the pasting machine, even if it is a wallpaper pasting machine arranged so as to embed a part of the compact slitter unit inside the main body. An object of the present invention is to obtain a wallpaper pasting machine capable of applying a good tension. Another object of the present invention is to obtain a wallpaper pasting machine capable of changing the tension bar according to the folding of the leg and the mounting of the wall covering.

According to a first aspect of the present invention, there is provided a wallpaper pasting machine in which a sheet-like wall covering is moved along a predetermined path by a plurality of rollers that are rotationally driven in conjunction with a motor, while the glue in the glue basket is used. A wall-paper gluing machine main body that continuously applies to the back surface of the wall covering material by a gluing roller, and both edges of the wall covering material that is detachably attached to and pulled into the rear portion of the gluing machine main body are continuously provided.

When the wall covering is bent at each part of the first and second tension bars and guided to the slitter unit and the gluing machine main body, the second tension bar is moved around the first tension bar. It is characterized in that it can be switched to three positions, that is, a wall covering material mounting state arranged immediately below one tension bar.

A wallpaper pasting machine according to the invention described in claim 3 is characterized in that the pair of tension bar holders according to claim 2
The first tension bar and the second tension bar are held so as to be slidable in a direction parallel to the axial center of each of the first tension bar and the second tension bar,

  The wallpaper pasting machine according to the invention described in claim 4 further comprises a tension bar different from the two tension bar groups on the upstream side of the transport path of the wall covering material. It is.

  Even if the wall paste is drawn into the slitter unit and the main body of the gluing machine, the present invention is good even if it is a wallpaper gluing machine arranged so that a part of the slitter unit that realizes compactness is embedded inside the main body. There is an effect that it is possible to obtain a wallpaper pasting machine capable of applying a large tension.

It is a front view of the wallpaper pasting machine of one example of the present invention. It is a side view of the wallpaper pasting machine of FIG. FIG. 3 is a side sectional view of the main body including the operation of the tension bar group shown in FIG. 2. FIG. 6 is a side sectional view of the main body including other operations of the tension bar group shown in FIG. 2.

In the present invention, in the wallpaper pasting machine provided with the slitter unit, the back surface of the pasting machine body includes a concave mounting portion formed in the body width direction,
The front part of the slitter part has a shape that can be fitted into the recessed mounting part.
Comprising at least two tension bar groups that bend the conveying path installed in the conveying path of the wall covering material leading to the slitter unit;
The tension bar group is rotatably connected to a first tension bar mounted in the width direction below the concave mounting portion of the gluing machine main body, and both ends of the first tension bar. By providing a pair of tension bar holders and a second tension bar that is held at both ends by the pair of tension bar holders, a part of the slitter part that achieves compactness is embedded inside the main body. Even when the wallpaper pasting machine is arranged, it is possible to obtain a wallpaper pasting machine capable of applying a good tension when the wall covering material is drawn into the slitter unit and the pasting machine main body.

When the wall covering is bent at each part of the first and second tension bars and guided to the slitter unit and the gluing machine main body, the second tension bar is moved around the first tension bar. It is possible to switch to three positions of the wall covering material placement state arranged immediately below one tension bar. Thereby, it becomes possible to change a tension bar according to the time of the folding of a leg part and the mounting | wearing of wall covering.

More preferably, the pair of tension bar holders is
The first tension bar and the second tension bar are held so as to be slidable in a direction parallel to the axial center of each of the first tension bar and the second tension bar,
At the wide first slide position, it comes into contact with a part of the vertical wall of the leg for preventing the rotation with the first tension bar as the rotation center, and at the narrow second slide position, the first slide A contact portion that does not prevent rotation with the tension bar of 1 as the rotation center is provided. This makes it possible to satisfactorily change the tension bar when the wall covering material is attached.

  As the wallpaper pasting machine main body of the present invention, the sheet-like wall covering material is moved along a predetermined path by a plurality of rollers that are rotationally driven in conjunction with a motor, and the glue in the glue basket is moved by the pasting roller. Wall paper pasting machine main body that is continuously applied to the back surface of the wall covering material, and a slitter section that continuously cuts both edges of the wall covering material that is detachably attached to the rear portion of the main body of the pasting machine. In particular, it is preferable that the effective width length of the plurality of rollers is 1000 mm or less and 920 mm or more. As a result, the length of the plurality of rollers is shortened by about 10%, and compactness is achieved by the shortened length.

  Since the wallpaper gluing machine is an apparatus that has been manufactured and sold before the standards for wall coverings are determined by JIS, the effective gluing width was 1050 mm. After that, the standards for wall coverings were decided. The majority of wall coverings have a maximum width of 920 mm ± 5 mm. For this reason, in the present invention, by setting the effective width length of the plurality of rollers to 1000 mm or less and 920 mm or more, the majority of wall covering materials can be used.

  Further, the wallpaper pasting machine main body of the present invention has a concave mounting portion formed in the width direction of the main body on the rear surface, and the slitter portion of the present invention has its front portion indented into the concave mounting portion. It only needs to have a shape that can be attached. Thereby, a slitter part does not protrude greatly behind a pasting machine, but gives a compact impression around.

  The slitter unit is attached to the mounting unit by, for example, a mechanism that is detachably fitted to a pair of left and right mounting units. Specifically, a pair of cylindrical supported portions projecting inward from both the left and right inner wall portions of the gluing machine main body constituting the opening of the slitter mounting portion are formed. A support part that is pivotally supported by the supported part, and a thing that is hooked to the latched part provided at the upper part of the mounting position of the gluing machine main body by turning around the support part can be attached and detached. Done well.

  The latching between the latching part and the latched part is preferably the upper part of the left and right inner wall parts of the gluing machine main body, the latched part constituting the slitter mounting opening, similar to the supported part. It is only necessary to form a pair of cylindrical hooking portions projecting inwardly facing each other, and as a hooking portion for this, the mounting position of the gluing machine main body is centered on the support portion. A notched ring with a notch on the side rotating to the hooked portion provided at the top is provided. The notch length of this notch ring can be attached and detached with one touch if it is smaller than the diameter of the cylindrical hooked part so that the arm part adjacent to the notch part of the notch ring part can be bent and attached. It becomes possible.

  Depending on the material and type of the wall covering material, when a satisfactory tension cannot be applied only with the tension bar group of the present invention, a separate tension bar from the two tension bar groups is transported. By providing further on the upstream side of the path, it is possible to apply good tension.
