Description

For example, the present invention is a wallpaper roll with paste, which is pasted on the back surface of wallpaper to be stuck on a wall surface during interior construction, and is covered with a release sheet and wound into a roll. The present invention relates to a wallpaper winding device and a gluing machine equipped with a wallpaper winding device for producing a wallpaper roll having a predetermined width by cutting the edges of the wallpaper.

Among a plurality of rollers that are driven to rotate in conjunction with a motor, a pair of pinch rollers that pinch the sheet-like wall covering material from the front and back surfaces move it along a predetermined path from the rear surface of the main body, while the paste is also driven to rotate. After the glue liquid in the glue tub applied to the glue application roller by the raising roller is squeezed to the glue thickness corresponding to the gap with the doctor roller, the wallpaper is continuously applied to the back surface of the wall covering material and discharged to the front surface of the main body. A gluing machine has already been proposed as a device for applying a paste mainly composed of starch paste to the back surface of wallpaper (see, for example, Patent Document 1).

This wallpaper gluing machine is rarely owned by an individual, and is owned by an interior builder. Mainly, we brought in a machine and applied paste to the back of the wallpaper to construct the interior.

However, the paper with glue discharged at a constant speed from the gluing machine or the wallpaper with cut paper, if the rotation speed of the winder was constant, the diameter of the paper with glue wound into a roll. When the diameter is large, the winding speed becomes faster than when the diameter is small, and the thickness of the paste becomes different between the inside and the outside of the wallpaper roll with paste carried out from the gluing machine at the same speed. Since it is attempted to wind at a speed higher than the carry-out speed, a burden is placed on the winding motor. Therefore, it is necessary for the operator of the winder to perform an operation to reduce the speed at the end of winding relative to the speed at the beginning of winding, and the operator has to be constantly with the winder. .

As a result, when operating the winder, the operator can wind up the wallpaper pasted with the paste by the gluing machine while keeping the thickness constant.

That is, in the present invention, a wall covering material with glue carried out from a wallpaper gluing machine or a wall covering material cut into a predetermined width carried out from a wallpaper cutting machine is wound up by rotation of a winding motor. Take-up device. Specifically, this winding device uses a winding shaft that rotates a winding motor to rotate pasted wall covering materials or wall covering materials that have been cut to a predetermined width by a wallpaper cutting machine. It is wound into a roll. A constant tension is applied to the wall covering material wound up by the winding shaft of the winding device in the direction from the front surface to the back surface of the wall covering material by means of a tension bar.

That is, when viewed from the side, the conveying path of the wall covering material is bent in a "<" shape by the tension bar. The diameter of the wall covering material increases from the early stage to the later stage when the wall covering material is wound around the winding shaft. For this reason, with a winding shaft that responds at a constant rotational speed, the speed is higher in the latter stage of winding. For this reason, in the transport path of the wall covering material urged by the tension bar, the tension is greater in the later period, and the amount of repulsion to the tension bar is greater.

In the present invention, the winding motor rotation control means varies the number of revolutions of the winding motor according to the amount of repulsion from the wall covering material of the tension bar, so that the wall covering material is wound around the winding shaft with a constant tension. As a result, when operating the winding machine, the operator can wind the wallpaper glued by the gluing machine at a constant thickness without being distracted by the operator. By providing a counting means for counting the winding amount, it becomes possible to automatically wind up the wall covering material together with the wallpaper pasting machine.

The urging means may be any one that urges the tension bar from the surface of the pasted wall covering material toward the back surface. A constant tension may be applied by the own weight of the arm, an elastic member such as a spring may be attached to the connecting arm, or the rotating shaft of the fulcrum may be urged in a constant rotational direction.

The winding motor rotation control means of the present invention may vary the number of revolutions of the winding motor according to the amount of movement such as the height position of the tension bar, and more preferably the winding motor rotation control means. However, as the amount of repulsion, the number of revolutions of the winding motor is varied according to the amount of movement of the tension bar lifted against the bias.

The pasted wall covering material of the present invention is rolled up after a release sheet is attached to the pasting surface of the pasted wall covering material before being taken up by the winding shaft. As a release sheet supply means for supplying the release sheet to the wall covering material with glue, after the release sheet is placed along the lower surface of the glued surface of the wall covering material with glue, the conveying path is formed in a "<" shape. A simple configuration such as an axis crossing the transport path to be changed may be used.

In addition, when pasting the cross-cut tape so that the glue does not adhere to the lower wall covering material when cutting after overlapping the wall covering materials, the glued wall should be cut before pasting the release sheet. This can be easily achieved by attaching a release sheet after attaching a cross-cut tape along both side edges of the covering material.

The gluing machine with the wallpaper winding device of the present invention includes the wallpaper winding device on the downstream side of the gluing machine so that the wall covering material is glued and wound into a roll. To enable an operator to wind wallpaper pasted with glue by a gluing machine while maintaining a constant thickness of the glue without being confused when operating the machine and the winder.

Therefore, in the winding shaft 32 that responds at a constant rotational speed, the speed is higher in the latter stage of winding. For this reason, in the conveying path of the laminated cloth C3 urged by the tension bar 33, the tension is greater in the latter stage, and the amount of repulsion to the tension bar 33 is greater. That is, the force for lifting the tension bar 33 against the urging force by the FI means increases and the tension bar 33 is displaced upward.

In this embodiment, as shown in FIG. 5, the weight 36 of the upper connecting arm 35 is used as winding motor rotation control means for varying the number of rotations of the winding motor according to the amount of repulsion of the tension bar 33 from the lamination cloth C3.
