Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for a wallpaper gluing machine that continuously applies gluing to the back surface of a sheet-like wall covering material that is attached to an interior wall surface or the like.

[0002]

2. Description of the Related Art Sheet-like wall coverings made of various materials, so-called wallpaper, is attached to the wall surface as an interior finish of a building. Usually, in the construction of this wallpaper, glue is applied to the back surface of the wallpaper at the site, and the wallpaper is sequentially attached to the wall surface. Conventionally, a wallpaper gluing machine has been used to apply glue to wallpaper. This wallpaper gluing machine is equipped with multiple rolls and glue tubs inside the main body, pulling in the wall coverings fed from the raw roll supported at the rear of the main body from the rear of the main body, sending it forward with various internal rolls, The glue in the tub is applied by bringing the backside of the wall covering material into contact with the gluing roll on the way.

Such a gluing machine main body is usually placed on a pedestal portion with legs for use. The gluing machine support structure consisting of this pedestal and legs is also transported to the site together with the gluing machine body and assembled and installed before use. A type in which the part can be folded and stored from the left and right sides of the pedestal part to the back side is becoming popular.

Tension bars are installed on the left and right ends of the legs of this support structure, and the tension bars are pressed against and abutted against a wall material in the middle of the conveying path which is drawn from the original roll to the rear part of the gluing machine. Applying tension to the equipment. At present, two tension bars are generally provided, so that the glue is evenly applied to the entire back surface of the wall covering so as not to cause wrinkles in the wall covering. It gives moderate tension.

[0005]

Conventionally, in the pasting work using a wallpaper pasting machine, a slitter is mounted on the rear part of the main body of the pasting machine, and the end (ear) of the wall covering is cut by the slitter. After adjusting the width to a desired width, it is generally drawn into the main body of the gluing machine and glued.

On the other hand, in many cases, the raw material of the wall covering material is handled vertically for transportation. Therefore, both ends of the original fabric may be crushed by the weight. The crushed portions at both ends of the original fabric are wrinkled when the wall covering is expanded.

Such a large crushed portion at both ends of the original sheet cannot be fully spread by applying tension by the usual two tension bars as described above, and the remaining wrinkle portion is exactly the cutting position by the slitter. If it becomes, the end portion of the wall covering material cannot be cut straight, resulting in a defective wall covering material.

Therefore, it is conceivable to increase the number of tension bars by one in order to extend such wrinkles at both ends. However, simply increasing the number of tension bars will result in excessive tension and a large load. Each roller that tries to convey the wall covering material to the front side in the main body of the gluing machine slips and idles, and it becomes impossible to satisfactorily convey and paste the wall covering material.

In view of the above-mentioned problems, an object of the present invention is to apply a wallpaper paste which can always cut straight edges by extending wrinkles caused by crushing of both ends of a raw material without causing troubles in transportation and gluing work of wall covering materials. It is to provide a support structure for the machine.

[0010]

In order to achieve the above object, the support structure of the wallpaper sizing machine according to the invention as defined in claim 1 has a sheet-like wall covering drawn in from the rear through a slitter. A pedestal for mounting a slitter-mounted gluing machine main body that applies glue to the back surface of the wall covering when pulling out to the wall portion, a leg portion arranged below the pedestal, and the gluing machine main body In the support structure of the wallpaper gluing machine, which comprises a tension bar that applies tension by contacting a wall covering on the way of the transport path from the original roll supported to the rear of the section toward the slitter, An auxiliary tension roll, which comes into contact with the wall material immediately before being drawn into the slitter so as to be rotatable about its axis, is provided so as to be selectively movable between the contact position and a retracted position away from the corresponding contact position. is there.

A support structure for a wallpaper sizing machine according to a second aspect of the present invention is the support structure for a wallpaper sizing machine according to the first aspect, wherein the auxiliary tension roll is fixed to the abutting position. The lock mechanism is releasably provided.

In the present invention, in the support structure for mounting and supporting the main body portion of the wallpaper sizing machine on which the slitter is mounted on the pedestal, the slitter is drawn into the wall covering material in the conveying path in addition to the normal tench bar. Since it is equipped with an auxiliary tension roll that makes axial rotation contact at the immediately preceding position, this auxiliary tension roll makes contact with the wall material being conveyed and rotates while following it, while driving the drive roll on the main body side of the gluing machine. Appropriate tension is applied without giving enough load to slip, and even if strong wrinkles are generated at the ends of the wall covering material due to the crushing of both ends of the original fabric, it can be extended just before being pulled into the slitter, The straight slitting is always possible in the slitter.

Further, since the auxiliary tension roll of the present invention is installed so as to be movable between the contact position with respect to the wall covering material and the retracted position away from the corresponding contact position,
If there are no strong wrinkles on both ends of the wall covering, move it to the retracted position and wait to prevent the auxiliary tension rolls from applying extra load to the drive system of the wallpaper gluing machine body. However, it can be moved to the contact position and used only when it is necessary to extend the wrinkles.

Incidentally, the immediately preceding position where the auxiliary tension roll is installed in the present invention means the auxiliary position at the upstream side from the position where the slitter stay and the tension board are pulled in to the wall material sandwiching portion on the slitter side. The distance should be within a distance where the tension roll can keep the wrinkles extended. The actual position may be appropriately set according to the retracting structure of the slitter.

Further, when the auxiliary tension roll is used, it is preferable to provide a lock mechanism capable of fixing the contact position thereof. If the abutment position can be fixed by the lock mechanism, during cutting and gluing work of wall coverings,
A situation in which the auxiliary tension roll moves due to vibration of the device and the contact is disengaged is avoided.

Needless to say, the support structure according to the present invention is effective regardless of whether the wallpaper gluing machine is a manual type or an automatic type. Even if the legs of the support structure are foldable, there is no problem as long as the setting position of the auxiliary tension roll is set so as not to affect the fold. Rather, the contact position immediately before being pulled into the slitter is close to the pedestal, and it can be said that the position where the folding of the legs is not most affected.

FIG. 1 shows a support structure of a wallpaper sizing machine according to an embodiment of the present invention. FIG. 1 is a schematic partial configuration diagram centering on an installation region of an auxiliary tension roll of the support structure of the present embodiment, FIG. 1A is a side view when the auxiliary tension roll is in a contact position, and FIG. It is a side view when an auxiliary tension roll is in a retracted position.

The basic structure of the support structure according to this embodiment is the same as the conventional structure. That is, mainly, the pedestal portion 1 on which the gluing machine main body portion 20 having the slitter 21 mounted on the rear portion is placed, and the lower left and right end portions of the pedestal portion 1 for supporting the gluing machine main body portion 20 at a predetermined height. The legs 2 arranged on the
It is composed of a cloth original (sold separately) to slitter 2
1 and a first tension bar T1 and a second tension bar T2 for applying a tension by pressing and abutting the wall covering material C before cutting and sizing toward the main body 20 of the gluing machine at a predetermined position in the conveying path. It is equipped with.

The wall covering C is a main body 2 of the gluing machine on the base 1.
0 is fed from a cloth cloth (not shown) axially supported by a wall covering support portion (not shown) provided at the rear of 0 to the gluing machine main body 20 through a slitter 21. The first tension bar T1 and the second tension bar T2 come into contact with the material C from the rear surface side and the front surface side, respectively, between the left and right leg portions 2 on the rear side of the gluing machine or the pedestal portion 1 It is installed on the rear side along the width direction of the main body (width direction of the wall covering material).

Further, in the present embodiment, above the two tension bars (T1, T2) of the leg portion 2 (downstream in the wall material conveying direction), the slitter stay 22 of the slitter 21 and the rotation for cutting the wall material are cut. An auxiliary tension roll Ts is provided at a position almost immediately before being drawn between the blade 23 and the tension board 24 that presses the wall covering material C against the blade 23.

Here, the auxiliary tension roll Ts is positioned about 2 cm below the lower end of the slitter stay 22 so that the auxiliary tension roll Ts keeps the wrinkle extended and pulls it into the slitter. In the current wallpaper sizing machines and slitters, it is desirable that the distance is substantially up to about 5 cm from the lower end of the slitter stay and is closer than that.

The auxiliary tension roll Ts is rotatable about its axis and is in contact with the wall covering C (see FIG. 1).
(A)) and a retracted state separated from the contact position (Fig. 1).
It is provided so that it can be selectively changed between (b)).

In this embodiment, the auxiliary tension roll Ts is pivotally supported by the other ends of the pair of arms 6 attached to both ends of the fixed portion 2 of the first tension bar T1 so that one end is rotatable. By doing, the auxiliary tension roll T
s can be selectively moved between an abutting position at which it comes in contact with the wall covering C being conveyed in a rotatable manner and a retracted position where the contact with the wall covering C is released.

Further, in the present embodiment, while the auxiliary tension roll Ts is in contact with the wall covering C, cutting by the slitter 21 and gluing work in the wallpaper gluing machine main body 20 are in progress. In addition, in order not to unnecessarily move from the contact position to the retracted position due to the vibration of the device,
A lock mechanism was provided to fix the contact position.

In this lock mechanism, a lock piece 7 is provided so as to project from an extension tip of an arm portion 6 which axially supports the auxiliary tension roll Ts, and the lock piece 7 is locked at a predetermined contact position of the auxiliary tension roll Ts. First tension bar T1
Is supported by the arm member 4 supporting the leg portion 2.

In the support structure of the wallpaper gluing machine according to the present embodiment having the above-mentioned structure, the wall covering C fed from the cloth original fabric is pressed by the second tension bar T2 and the first tension bar T1. It is drawn into the slitter 21 while tension is applied by abutment and the wrinkles and slacks are extended as a whole, and the ends are cut and adjusted to a desired cross width, and then the wallpaper paste machine main body portion 20 is rear-mounted. When it is pulled in from the cloth and is conveyed forward while the back surface is continuously coated with glue, there are crushed edges on this cloth cloth, and strong wrinkles occur on both ends of the wall covering C that is being fed out. Has
It suffices to rotate the arm portion 6 to move the auxiliary tension roll Ts to the contact position and lock it with the lock mechanism.

Since the auxiliary tension roll Ts is rotatable about its axis and can rotate following the progress of the abutting wall covering C, it does not give a large load to stop the conveyance of the wall covering C. , The wrinkle that has passed through the first tension bar T1 and comes into contact with the wall covering material C with an appropriate tension to extend the wrinkles that could not be extended by the other tension bars, so that the slitter 21 always performs straight cutting. be able to.

If strong wrinkles due to crushing of both ends of the original cloth do not occur, the lock mechanism is released and the auxiliary tension roll Ts is moved away from the contact position with the wall covering C to the retracted position. The unnecessary load on the drive system of the main body 20 of the wallpaper sizing machine due to the auxiliary tension roll Ts is completely eliminated.

Even if the supporting structure is a leg folding type, the installation of the auxiliary tension roll Ts as described above has an influence on the folding, such as above the folding connecting portion 10 of the leg 2 as in the present embodiment. There is no problem if you set it to a non-existent position.

In the above embodiment, the auxiliary tension roll Ts is rotatably supported by the fixed portion 5 of the first tension bar T1 via the arm portion 6, and the first tension bar T1.
The case where the lock mechanism that locks the arm member 4 that supports the member at the contact position is provided is shown, but the auxiliary tension roll of the present invention is not limited to this configuration, and the first tension bar T1 is fixed. A pivotal support mechanism or a lock mechanism may be provided on the leg portion 2 above the portion 5 or the pivotal support portion 3 of the arm member 4 so as to have a stationary structure.

Further, the auxiliary tension roll Ts can be detached from the support structure together with the arm 6 so that it can be easily handled during storage and transportation, and can be attached and detached so that it can be mounted when assembling the gluing machine on site. Also good.

[0032]

As described above, according to the supporting structure of the wallpaper sizing machine of the present invention, strong wrinkles, which cannot be extended by the conventional tension bar alone, such as those caused by the crushing of both ends of the cloth original fabric, are applied to the wall covering. Even if it occurs at the end of the material, the auxiliary tension roll that can rotate the axis does not hinder the transport of the wall covering material and extends the wrinkle to enable straight cutting in the slitter, and the glued cloth This is effective in preventing defective products due to bending of cutting.
