BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wallpaper cutting device for cutting an edge portion of a wall covering material and adjusting the width of the wall covering material to a predetermined width before supplying the cut wall paper.

[0002]

2. Description of the Related Art Conventionally, in a wallpaper sizing machine, a main body of a wallpaper sizing machine which applies glue to the back surface of a long sheet-like wall covering while being pulled in from the rear and pulled out from the front is used. A wall cutting device is attached with a hook or the like, and the side edges of the wall covering are sheared along the transport direction to adjust the wall covering to a desired width.

[0003] A wallpaper cutting device for a conventional general wallpaper sizing machine includes a pair of upper and lower rotary blades at opposing positions of upper and lower shafts provided in parallel in a direction perpendicular to the direction of wall material conveyance. , An overcutter (upper blade) and an undercutter (lower blade) are fixed to each other, and this pair of cutters cuts the wall covering material from above and below.

In order to prevent the side edge of the cut wall covering material from being drawn into the main body of the wallpaper sizing machine, a guide portion for guiding the side edge to the outside of the main body of the sizing machine and discharging the same is provided. It is attached to the stay of the gluing machine body. This guide section is movable in the width direction of the wall covering, adjusts the position of the guide section according to the width of the wall covering to be conveyed, and glues the sheared wall covering side edges. It is designed to be guided outside the machine body.

[0005]

However, in such a conventional wallpaper cutting device, since the guide portion is attached to the sizing machine main body side, it is rotated to adjust the width and the cutting position on the wall material. When adjusting the position of the blade on the shaft, the position of the guide portion must be adjusted in addition to the position of the rotary blade. For this reason, there is a problem that the work load of the worker becomes excessive.

In addition, since the position of the guide portion must be adjusted separately from the rotary blade, if the position of the guide portion is insufficiently adjusted, the guide of the side wall portion of the wall material after cutting is not performed well. It is drawn inside the gluing machine body. If the side edge is wrapped around, for example, a roll of the sizing machine in the sizing machine main body, there is a risk that the roll may be distorted or damaged.

In addition, if the guide portion prevents contact between the lower blade and the upper blade due to insufficient position adjustment of the guide portion, it is impossible to cut the side edge of the wall covering material. is there.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and a guide part is attached to a rotary blade to simplify the operation of adjusting a cutting position of a wall covering material, thereby reducing a work burden on an operator. It is a main object to provide a wallpaper cutting device that can be reduced. Another object of the present invention is to provide a wallpaper cutting device that facilitates position adjustment of a guide portion, reliably guides a cut side edge portion, and prevents breakage of a sizing machine main body part. It is to be. Another object of the present invention is to provide a wallpaper cutting device capable of reliably performing a wall covering material cutting operation.

[0009]

Means for Solving the Problems In order to achieve the above object, an invention according to claim 1 is a wallpaper for cutting a side edge portion of a wall covering material along a carrying direction while carrying a sheet-like wall covering material. The cutting device has a boss portion that can be adjusted on the shaft, has a rotary blade that is driven to rotate, and a guide portion that guides the cut side edge portion of the wall covering material to the outside of the gluing machine main body. The guide portion is detachably attached to the rotary blade.

The rotary blade of the present invention has a boss in addition to the blade, and the boss has a blade attached thereto. Since the position of the boss of the present invention is adjustable on the shaft, the position of the rotary blade is adjustable in the width direction of the wall covering. And since a guide part is attached to a rotary blade, if a boss part is moved on a shaft and position adjustment of a rotary blade is performed, a guide part will also move integrally with a rotary blade and position adjustment will be performed. . For this reason, when adjusting the cutting position of the side edge portion of the wall covering, the operator only needs to adjust the position of the rotary blade only, and the conventional method has to separately adjust the position of the rotary blade and the guide portion. Position adjustment work is simpler than that of a wallpaper cutting device.

Further, according to the present invention, since the position of the guide portion can be adjusted integrally with the boss portion of the rotary blade, there is no problem that an unnecessary gap is generated between the guide portion and the rotary blade. The guided side wall portion of the wall covering material can be reliably guided to the outside of the main body of the gluing machine. Therefore, it is possible to prevent the sizing machine main body from being damaged due to the cut side edge portion being drawn into the sizing machine main body.

The configuration of the rotary blade is not particularly limited as long as it cuts the side edge of the wall covering material to be conveyed along the conveying direction. It is optional to configure a pair of upper and lower rotary blades that can be driven to rotate, or a single-blade rotary blade. In particular, when a pair of upper and lower rotary blades is used, it is possible to prevent the presence of the guide portion whose position is insufficiently adjusted to prevent the rotary blades from coming into contact with each other and hinder cutting of the side wall portion of the wall covering material. The cutting work of the material can be performed reliably.

The configuration of the guide section of the present invention is not particularly limited as long as it is attached to the rotary blade. For example, in addition to being attached to the boss portion of the rotary blade, the rotary blade may be provided with a mounting portion dedicated to mounting the guide other than the boss portion, and the guide portion may be mounted on this mounting portion. In this case, it is possible to easily attach and detach the guide portion.

When a pair of upper and lower rotary blades is used as the rotary blade, such a guide portion is configured to be attached to one of the pair of rotary blades for simplification of the structure. be able to. When a pair of rotary blades are integrally formed so as to slide the shaft, the rotary blade may be attached to one rotary blade or to both rotary blades.

In the present invention, since the guide portion is detachably attached to the boss portion of the cutting device instead of the sizing machine main body side, the size of the sizing machine can be reduced.

In a mode in which the wallpaper cutting device according to the present invention is attached to a gluing machine main body, a sheet-like wall covering material is drawn in from the rear of the main body portion and is drawn out from the front while glue is applied to the back surface of the wall covering material. A wallpaper sizing machine for applying a stencil, which has a boss portion capable of adjusting the position on a shaft, and a rotary blade that cuts a side edge of the wall covering material along a transport direction by being driven to rotate, and is cut. A guide portion for guiding a side edge portion of the wall covering material to the outside of the gluing machine main body, wherein the guide portion is attached to a boss portion of the rotary blade. is there.

According to the present invention, a wallpaper cutting device according to claim 1 is provided in a gluing machine, and has the same operation and effect as the invention according to claim 1.

The wallpaper sizing machine of the present invention is not only an automatic wallpaper sizing machine for automatically gluing while transporting wall coverings, but also a manual wallpaper sizing machine for manually transporting and gluing wall coverings. Both are included.

Together, they constitute the boss of the present invention. The upper blade fixing boss 5a is positioned by tilting a lock lever (not shown) on the boss to a flat portion of the upper blade shaft 4a. Thereby, the upper blade 7a is also positioned on the shaft. Therefore, even if the shaft is rotated,
Friction does not easily occur between the shaft and the lock lever, and the shaft does not wear. On the other hand, by releasing the lock lever, it becomes possible to slide on the upper blade shaft.

Similarly, the lower blade boss 5c is positioned by tilting a lock lever (not shown) on the boss to the flat portion of the lower blade shaft 4b, whereby the lower blade 7b is also positioned. By releasing the lock lever, the lower blade mounting boss 5b to which the lower blade boss 5c and the lower blade 7b are mounted can both slide on the lower blade shaft.

As described above, each rotary blade slides on each shaft together with each boss so that the position of the cloth 11 can be adjusted in the width direction.

The spring 6 has both ends in contact with the lower blade 5c and the lower blade mounting boss 5b, respectively. Then, the lower blade mounting boss 5b is pressed toward the upper blade side (to the right in FIG. 2) by the elastic force of the spring 6, so that the blade surface of the lower blade 7b always contacts the blade surface of the upper blade 7a. , The cross cutting is assured.

The guide portion is bent in a substantially arc shape directed outward. Cloth 11 cut by a pair of rotary blades
The side edge portion 12 of the guide portion advances along a curved portion of the guide portion as the cloth 11 is pulled from the gluing machine main body portion. For this reason, the cut side edge portion 12 is guided to the outside of the sizing machine main body so as not to be drawn into the sizing machine main body.

As shown in FIG. 2A, on the opposite side (right side in FIG. 2) of the lower blade mounting boss 5b across the lower blade 7b, a guide mounting extending in the axial direction of the shaft from the lower blade 7b. Part 5d
Is provided. The guide portion is detachable from the guide mounting portion 5d. FIG. 2 (a)
FIG. 2B shows a state where the guide portion 8 is not attached to the guide attachment portion 5d, and FIG. 2B shows a state where the guide portion is attached to the guide attachment portion 5d. As shown in FIG.
The guide portion is fixed to the lower blade mounting boss 5b by fitting a substantially U-shaped portion at the base of the guide portion into the guide mounting portion 5d.

Next, a wallpaper gluing machine 20 provided with the cutting device 1 of the present embodiment will be described. As shown in FIG. 3, the sizing machine main body 20 is provided with a cloth 11 taken from the rear side into the sizing machine main body 20 in the upper structure 21 as a main roll, in front of the sizing machine main body 20. The pressing stay 24 for applying the feeding tension in the direction of the section and the drive roll 25 which presses the cloth 11 from above and rotates following the cloth 11 are arranged on the side plates of the upper structure 21 so as to be arranged in parallel at predetermined intervals. It is pivoted.

In the lower structure 22, the glue contained in the glue tub 23 is glued downward, and the glue roll 26 is applied to the back surface of the cloth 11 conveyed above.
A doctor roll 27 that contacts the gluing roll 26 to adjust the amount of glue;
The leveling rolls 28 that apply an appropriate tension to 1 and are fed in the front direction are pivotally supported on the side plate of the lower structure 23 so as to be arranged in parallel with a predetermined interval therebetween.

When the side edge 12 is cut by the cutting device 1 and the cloth 11 adjusted to a predetermined width is glued, first, the lock lever (for the upper blade fixing boss 5a and the lower blade boss 5c) is used. (Not shown) is released, the upper blade 7a and the lower blade 7b are moved on each shaft and positioned so as to have a predetermined wallpaper cutting width, and then each boss is fixed by each lock lever. Thereby, the guide part attached to the guide attachment part 8 is also positioned at the same time.

As described above, in the cutting apparatus 1 of the present embodiment,
Since the guide portion is mounted on the guide mounting portion of the rotary blade of the cutting device 1 instead of the gluing machine main body, if the lower blade mounting boss 5b is moved on the shaft, the guide portion also moves accordingly. I have. For this reason, even when adjusting the cutting position, it is not necessary to adjust the position of each boss and the guide part separately, the position adjustment is simplified, and the work load on the operator is reduced.

After the positioning of the rotary blades and the guides, the tip of the cloth 11 is pulled out from the cloth cloth 10 which is supported by the cross receiving bracket 31 extending rearward from the sizing machine leg 30, and the wallpaper cutting device 1 From the back side of the device, and is pulled out from the front of the device after passing between the rotary blades.

After the initialization is completed, the driving of the driving source motor (not shown) of the gluing machine is started, and the driving of the motor (not shown) of the cutting device 1 is started. As a result, the cutting of the side edge portion 12 by the rotation of each rotary blade as the cloth 11 passes through the cutting device 1 and the sizing of the cloth 11 in the sizing machine main body 20 after the width adjustment by the cutting are performed. It is performed continuously.

Since the guide portion is positioned at an optimum position with the adjustment of the position of the lower blade mounting boss 5b, the lower blade 7b
Unnecessary gaps are not created between the guide and the guide portion 8, and the cut side edge portion 12 is not drawn into the sizing machine main body together with the cloth 11. The cutting operation of the cloth 11 can be reliably performed without the guide portion 8 preventing the upper blade and the lower blade from contacting each other due to a defect in the position adjustment of the guide portion.

The cutting device 1 cuts both side edges 12 of the cloth 11 even if it has a pair of upper and lower rotating blades for cutting one side edge 12 in the width direction of the cloth 11. For this purpose, a pair of rotary blades facing each other in the cross width direction may be provided at both ends.

Further, in the above-described embodiment, the case where the separate cutting device 1 is attached to the wallpaper sizing machine has been described, but a configuration in which the rotary blade is integrally provided in the sizing machine may be adopted.

Further, in the above embodiment, the case where the cutting device 1 is attached to the manual gluing machine is shown, but it goes without saying that the cutting device 1 can be attached to the automatic gluing machine.
