Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wallpaper sizing machine, and more particularly to a wallpaper sizing machine equipped with means for surely supporting an original roll of wallpaper.

[0002]

2. Description of the Related Art Conventionally, when pasting wallpaper,
There are two types of construction methods, which are stack cutting construction and butt construction. The former lap cutting construction is a method in which adjacent wall papers are overlapped and pasted, a ruler or an alternative to the ruler is applied to the overlapped portions, and the overlapped portions are cut with a cutter from the top, so that the joints are fitted together exactly. The latter butt construction is a method in which both ends of the wallpaper are cut at the time of gluing with a width cutting machine slitter set on the gluing machine, and the cut surfaces of the adjacent wallpapers are butted against each other.
Especially in the latter case, it is necessary to cut the wallpaper into a predetermined width and to machine the cut surface into a straight line.

In a conventional wallpaper sizing machine, a round bar having a diameter smaller than that of a paper tube (generally, a round bar having a diameter of 12 mm), which is a core of a roll of wallpaper, is used as a roll of core for a roll of wallpaper. Pass through the center hole, support the end face of the original roll with the end face pressing plate, pull the leading end of the original fabric toward the gluing process part or width cutting process part,
The original of the wallpaper is unraveled.

Since the diameter of the paper tube, which is the core of the original wallpaper, varies depending on the wallpaper maker and the type of wallpaper, an original core rod having a considerable play with respect to the paper tube diameter is used. Both ends of the original roll are supported by end face pressing plates, but since the center of gravity of the original fabric and the center of the original fabric core do not coincide with each other, they do not rotate properly, so the tension of the wallpaper is not constant. As a result, the conveyance to the slitter becomes unstable, and the width dimension during cutting and the linearity of the cut surface are deteriorated.

In order to improve such an unstable element, a tension stay (tension bar) is provided between the unraveling and the slitter entry to apply tension to the wallpaper,
Flapping (instability) during transport to the slitter was reduced. However, if the tension is increased so that the wallpaper is fed stably when entering the slitter, a considerably large force is required to pull up the wallpaper.

Many of the original fabrics are not stored in a perfect circular state, and some of them cannot be rotated properly when unraveled. In such a product, the core portion (whether with or without a paper tube) is deformed into an elliptical shape, uneven rotation occurs in the raw core rod having a small diameter, and the tension of the wallpaper also pulsates. In order to improve this, as shown in FIG. 5, there is a method in which a tapered cone is inserted into the core of a raw roll and the outside is pressed by an end face pressing plate.

[0007]

However, the conventional method using the tapered cone has a problem that the end face of the original roll cannot be supported. That is, in the wallpaper industry where the diameter of the paper core that is the core widely exists in various sizes,
When a tapered cone is used, when the center of the original roll is held, the position of the cone changes depending on the size of the paper tube diameter, so the end face cannot be supported at the same time as the center is held (see Fig. 5). ), It is difficult to ensure the linearity of the cut surface of the wallpaper.

The present invention solves the above-mentioned conventional problems to support the center of the roll of paper roll and the end faces of the roll of roll so that the roll of paper can be unraveled accurately and stably. The purpose is to do.

[0009]

In order to solve the above-mentioned problems, in the present invention, a wallpaper gluing machine is provided with first supporting means adapted to support the central hole of the original roll of the wallpaper by adjusting the central hole diameter. When,
A configuration including a supporting device having a second supporting means for supporting the end face of the original roll and a means for fixing the first supporting means and the second supporting means to the original core rod passing through the center hole of the original roll. And With such a configuration, the original wallpaper roll can be unraveled accurately and stably.

By aligning the center of gravity of the original roll with the center of the original core rod, the force required for unwinding is reduced. If a certain amount of tension is applied to the wallpaper, there will be no fluttering even if the wallpaper is not tensioned by applying a large amount of frictional resistance as in the conventional art. As a result, an automatic machine that pulls up with a motor can reduce the size of the motor, and a manual machine can realize a labor-saving machine that can be pulled up lightly.

Further, a taper-shaped core pressing means adapted to support the center hole of the original roll of the wallpaper and supporting the central hole, and an end surface of the original roll supported by sliding axially with respect to the core pressing means. And a supporting device having a core pressing means and a means for fixing the end pressing plate to the raw core rod passing through the center hole of the raw roll. With this configuration, the tapered core retainer and the end face retainer plate that support the center portion slide with each other, and the center of gravity of the original fabric roll and the center of the original fabric core rod coincide with each other. Makes the force uniform and the tension on the wallpaper constant. By applying a constant tension, the flapping of the wallpaper in front of the slitter (specifically, before the cutting point) is eliminated, and it is possible to cut in a stable transport state. Some original rolls are crushed in an elliptical shape, but the center of gravity can be captured by inserting a tapered core retainer.

Further, chuck means for supporting the center hole by an inner chuck in conformity with the central hole diameter of the original fabric roll of the wallpaper, an end face pressing plate for supporting the end face of the original fabric roll, and a central hole of the original fabric roll are provided. A supporting device having a chuck means and a means for fixing the end face pressing plate to the passing raw core rod is provided. Even with this configuration, the original wallpaper roll can be unraveled accurately and stably.

Further, collet means for supporting the central hole by an expander and a collet according to the central hole diameter of the original roll of the wallpaper, an end face pressing plate for supporting the end face of the original roll, and the center of the original roll. A supporting device having a collet means and a means for fixing the end face pressing plate to the raw core rod passing through the hole is provided. Even with this configuration, the original wallpaper roll can be unraveled accurately and stably.

Further, link means for adapting to the central hole diameter of the original roll of the wallpaper and supporting the central hole by using a link mechanism, an end face pressing plate for supporting the end face of the original roll, and the center of the original roll A supporting device having a link means and a means for fixing the end face pressing plate to the raw core rod passing through the hole is provided.
