BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chip guide for a slitter for a wallpaper sizing machine.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slitter for a wallpaper gluing machine, which effectively guides cut chips so as not to be caught in the gluing machine when ears at both ends of the wallpaper are dropped before gluing.

[0002]

2. Description of the Related Art Conventionally, when a wallpaper is applied to a wall or ceiling inside a building, the paste in the paste box is rolled up by a paste-up roller, and paste is applied to the back of the wallpaper by a paste-applying roller. Is used. The wallpaper to be used is made of a cover and a backing paper, and the backing paper is usually slightly longer in the width direction, so that only the backing paper is provided at both ends. Also, as a wallpaper construction method,
There is a butt construction method and an overlap cutting method, but in addition to the butt construction, it is common to cut both ends of the wallpaper to the desired width before gluing with this sizing machine, To trim the wallpaper to the desired width,
A slitter composed of an upper rotary blade and a lower rotary blade is used on the wallpaper supply side of the gluing machine. Then, the ears at both ends of the wallpaper are cut off by the slitter. A chip guide guide is used as a guide for discharging the cut chips.

Hereinafter, a conventional slitting machine for a sizing machine will be described with reference to FIGS. On the cloth B supply side of the wallpaper gluing machine, as shown in FIG. 9, a slitter A for a wallpaper gluing machine that cuts a side edge of the cloth by a pair of upper and lower rotating blades 2, 3.
Is provided. A guide 1 for chips C that curves toward the opposite side of the direction of travel of the wallpaper is provided outside the contact portions of the upper and lower rotary blades 2 and 3 in the width direction.

[0004] The cross cutting action in these conventional slitters is performed in the following procedure. First, the upper part of the gluing machine is opened, and the interrupting switch of the operation box is pressed to idle the gluing machine, and the rotary blades 2 and 3 of the slitter are rotated. Next, hold the tip of the cloth B with both hands and insert it into the back of the slitter A. When the tip comes out a little from the slitter A, pull it out with the tip, and pull the tip 20-30c.
m, stop once (because the chip tip does not rise to the guide portion of the chip guide 1 and is likely to slip through and enter the gluing machine), and use one hand to prevent the cloth B from sliding down While holding the cloth B, the chip C at the tip cut by 20 to 30 cm with the other hand is attached to the guide portion 1d of the chip guide 1, and the hand for holding the cloth B is changed to cut the other side. Put the debris C along the guide 1d of the guide 1, hold the tip of the cloth B with both hands, and pull it further. Lightly press the cloth on the roller of the gluing machine and pull it slightly out of the outlet of the gluing machine. Press the interrupt switch to stop idling, close the top and cut the cloth.

Further, during the gluing operation, if the edge of the cloth B is cut off or the end of the cloth B is crushed, the cloth B is not guided upward along the guide portion 1d of the chip guide 1, Since the paper passes through the side of the guide portion 1d and gets caught in the gluing machine, during the gluing, always check whether the chips C are smoothly discharged while folding the glued cross B. As soon as the chips C enter the sizing machine, the stop switch must be pressed to stop the sizing machine and to process the chips C.

[0006] When the chips C enter the sizing machine and are wrapped around the sizing roller as the processing, the sizing operation is stopped, the upper part is opened, the cloth in the middle of sizing is cut, and the sizing cloth is cut. , The operation box must be removed, and the tip of the chips C wound around the gluing roller 23 must be removed while the roller is reversed.

[0007]

In the conventional chip guide, since the guide portion is located outside the contact position between the upper blade and the lower blade, the tip of the chip of the cloth or the ear portion in the middle of the cloth is not formed. If it is crushed, the tip of the next chip does not rise along the guide, but passes through the side of the guide and enters the gluing machine side, enters the glue box, and in some cases, glues It wrapped around the roller and forcedly widened the distance between the doctor roller and caused the doctor roller to be distorted. The narrower the chip width and the weaker the waist of the cloth, the more difficult it is to go up along the guide, slip past the chip guide, accumulate chips at the guide part, It was also placed on the width-cut cloth, causing it to enter the gluing machine.

[0008] Once the swarf is wrapped around the sizing roller, the stop button is pressed, the sizing machine is stopped, and as described above, much work is required to restore the sizing machine, and the efficiency of the sizing operation is reduced. Was causing it.

As shown in FIGS. 1 and 3, the guide of the present invention has a shape in which a guide portion is provided with a laterally bulging portion. That is, when the guide 1 is set on the slitter, the protruding portions 1a and 1b which bulge toward the lower blade 3 side have a shape which bulges laterally slightly above the crossing position of the cross B as shown in FIG. I have. If the positions of the lower ends of the protruding portions 1a and 1b are too close to the passing position of the cloth B, there is a concern that they will be caught by the cloth, and if they are too far, they do not act as a guide.

The width of the protruding portions 1a and 1b is preferably 5 mm or more. If the width is small, the function of raising the chips upward cannot be sufficiently performed, and the chips may also be inclined obliquely and pass through the guide into the sizing machine. Normally, this chip guide is formed by injection molding. However, as shown in FIG.
Since it can be used as a guide on both the left and right sides, in view of productivity (mold cost, lot number, stock quantity, etc.), a shape having a protruding portion 1a swelling on both sides in the horizontal direction is preferable. In this case, the maximum cutting width is reduced by the amount by which the guide portion protrudes outward. Therefore, when importance is attached to the maximum cutting width, it is preferable to use a chip guide that protrudes only on one side as shown in FIG.

Next, a cross cutting operation using the slitter of the present invention will be described. First, in order to cut the width of the cloth to a desired width, the upper blade 2 is moved while looking at the scale plate 17 of the slitter A, and set to a desired width. Next, the lower blade 3 is pressed so that an appropriate spring pressure is applied to the upper blade 2.
