DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wallpaper sizing machine for continuously applying sizing to the back surface of a sheet-like wall covering material to be attached to an indoor wall surface, etc. The present invention relates to a wallpaper cutting device and a wallpaper sizing machine provided with the same.

[0002]

2. Description of the Related Art At present, a wall material is stuck to an indoor wall surface in an interior construction of a building by continuously applying glue to a sheet-like wall material using a dedicated wallpaper gluing machine at a site. It is common to do.

Recently, as such a wallpaper sizing machine,
Automatic gluing machines have become widespread. In this automatic wallpaper sizing machine, a rotating shaft of a driving mechanism such as a motor is connected to a rotating shaft end of the sizing roll, and the other slivers are interlocked via a gear by rotating the sizing roll electrically. The glue is scooped up from the glue tub while the cloth is automatically conveyed by the rotation of, and applied to the back of the cloth.

[0004] In such an automatic wallpaper sizing machine, a cutting device for cutting a side edge of a cloth and adjusting the width to a desired width is generally detachably mounted before applying the glue. ing. In this cutting device, the cross side edge is cut by sandwiching the cloth between a pair of upper and lower rotating blades or by transporting the cloth while pressing the cloth from the back surface side with one rotating blade. Sent from the rear side to the attached machine body.

In such a conventional wallpaper sizing machine, the cloth is usually unwound from a web roll rotatably supported on the rear side of the sizing machine main body, and is tensioned by a leg supporting the main body. It is conveyed through a bar and introduced into a cutting device.

[0006]

However, in such a conventional wallpaper gluing machine, since the tension bar is pivotally supported at a position diagonally below the cutting device, the cloth C is attached to the main body of the gluing machine. When trying to transport vertically along the rear wall surface, wrinkles, bending, etc. may occur in the cloth before it is transported to the cutting device, and in this state, the cloth is transported to the cutting device. When the cloth is cut, there is a problem that the side edge of the cloth cannot be cut well. In particular, when the cross side edge is cut by one rotary blade, that is, a single blade, the rotary blade is pressed from only the back side of the cloth. The risk of the blade not cutting the side edge well without contacting the cloth is very large.

In addition, the cloth may be wobbled and meandered before being conveyed to the cutting device. When the cloth is conveyed to the cutting device and cut in this state, the side edge of the cloth is removed. There is a problem that it cannot be cut straight.

The present invention has been made in view of such a problem, and wrinkles are formed on a wall covering material by pressing the wall covering material being conveyed by a holding stay while conveying the wall covering material in a vertical state. It is a main object of the present invention to provide a wallpaper sizing machine capable of preventing the occurrence of bending or the like and reliably cutting the side edge of the wall covering material. It is another object of the present invention to provide a wallpaper sizing machine that can cut a wall material side edge straight by preventing meandering of the wall material.

[0009]

In order to achieve the above-mentioned object, the invention according to claim 1 is directed to a sheet-like wall covering material pulled in from a rear surface portion of a main body by a plurality of rolls to a predetermined path in the main body. A wallpaper sizing machine for continuously applying glue to the back surface of a wall covering while moving the wall covering, wherein the wallpaper cutting machine is provided on the rear surface of the main body and cuts a side edge of the wall covering to be conveyed. In a wallpaper gluing machine equipped with a device, the wallpaper cutting device includes a guide unit that holds the conveyed wall covering material in a substantially vertical state, and a wall covering material that is held in a substantially vertical state by the guide unit. A rotating blade that cuts the blade while pressing the cutting edge from the back side, and guides the wall covering from the front side at a position upstream of the rotating blade with respect to the wall covering being conveyed by the guide portion. And a holding stay that holds down the part. It is intended.

In the invention according to the first aspect, the wall material being conveyed is pressed from the surface side of the wall material at a position upstream of the rotary blade by the holding stay, and in this state, one (one-sided) rotary blade is rotated. The cutting edge is pressed against the wall material from the back side to cut the side edge. For this reason, even if wrinkles, flexures, and the like occur before the wall covering material reaches the wallpaper cutting device, wrinkles, flexures, and the like are suppressed by the holding stay. For this reason, the wall covering material can be reliably pressed from the back side by the rotary blade, and the side edge portion can be reliably cut.

When the cutting device cuts the side edge while the wall covering is being drawn into the sizing machine main body in an inclined state or a horizontal state, the cut edge is cut by an inertial force acting on the wall covering. There is a danger that the portion will follow the wall covering body and be drawn into the inside of the body from the rear side of the gluing machine body, which will hinder the gluing operation. However, in the present invention, since the wall covering is held in a substantially vertical state by the guide portion, an inertial force toward the inside of the sizing machine main body does not act on the cut edge of the wall covering,
There is no possibility that the side edges are drawn into the gluing machine main body.

The holding stay in the present invention is preferably an upstream position immediately before the rotary blade, as long as it presses the wall covering material from the front surface side, and its shape and configuration are not particularly limited. For example, in addition to forming the holding stay in a rod shape, the holding stay may be formed of a plate-shaped member.

The guide portion in the present invention may be any as long as it holds the wall covering material in a vertical state. The housing extends in the vertical direction of the wallpaper cutting device, and the vertical slit through which the wall covering material passes. Any of these can be used as the guide portion.

According to a second aspect of the present invention, in the wallpaper gluing machine according to the first aspect, the holding stay has a surface wider than the width of the wall covering material to be conveyed over the entire width of the wall covering material. It is characterized in that the wall covering material is pressed down from the side.

According to the second aspect of the present invention, the holding stay presses the wall covering material from the front side over the entire width of the wall covering material with a width wider than the width of the wall covering material to be conveyed. Can be prevented, thereby making it possible to cut the side edge straight.

According to a third aspect of the present invention, in the wallpaper sizing machine according to the first or second aspect, a holding portion for holding the holding stay, and the holding portion are arranged from a front side of a wall covering material to be conveyed. Fixing means for holding the pressing stay in a state where a predetermined pressing force is generated toward the back surface side, wherein the holding portion includes a pair of arm portions that support the holding stay at both ends thereof, and a rear surface of the main body.

According to the third aspect of the present invention, as a configuration of the holding portion for holding the holding stay, a pair of arms for pivotally supporting the holding stay at both ends thereof are pivotally mounted on the rear side of the main body of the gluing machine. Since it is supported, the arm and the holding stay can rotate integrally and integrally. Therefore, by rotating the arm, the holding stay is rotated to be held by the fixing means, and is held by the two arms even when the holding stay is detached from the fixing means. For this reason, at the time of initial setting of the sizing work, when the wall covering material is pulled out from the raw material roll or the like and set on the sizing machine main body, the holding stay is removed from the fixing means and held in the arm portion, and the sizing machine is held. If the holding stay is rotated and held by the fixing means when the is operated, the work at the time of the initial setting can be easily performed.

The structure of the two arms in the present invention is not particularly limited as long as the two arms are rotatably mounted on the rear surface of the main body (or on the rear surfaces of the legs of the main body) and hold the holding stay. Not something. For example, a tension bar may be provided on the bearings of the two arms. In this case, if the wall covering was fed out through the tension bar, and the wall covering via the tension bar was pressed from the surface side by the holding stay, an appropriate tension was given by the tension bar. Since the wall covering is further pressed by the holding stay, the synergistic effect of the tension bar and the holding stay can more reliably prevent wrinkling and bending of the wall covering. Further, in this case, it is preferable that the tension bar be configured to rotate with the transfer of the wall covering so as not to hinder the transfer of the wall covering.

The fixing means holds the arm and the holding stay in such a state that a predetermined pressing force is generated from the front side to the back side of the conveyed wall covering. Here, the predetermined pressing force refers to a pressing force that eliminates wrinkles, bending, and the like generated in the wall covering and does not hinder the conveyance of the wall covering. Since the pressure is generated from the front surface side to the rear surface side of the wall covering material, it is possible to suppress wrinkles, bending, and the like while smoothly transporting the wall covering material.

Further, in the sizing machine main body 1 of the present embodiment,
A delivery roll 6 of the lower structure 2 is supported via a hinge 5 supported on a glue tub 4 in a detachable and rotatable manner, and at the same time, a rotating shaft of an electric motor (not shown) as a driving source. , And transmits the rotational motion of the electric motor to another roll interlocked via a gear.

In the automatic wallpaper sizing machine provided with the sizing machine body 1 having the above configuration, the delivery roll 6 is connected to the rotating shaft of the electric motor to transmit the rotating motion.
As in the conventional manual type, the glue roll 8 directly scoops the glue from the glue tub 4 and transfers the glue to the back surface of the cloth without providing a glue roll separately, so that the size and weight of the lower structure 2 are increased. Instead, it has a configuration that is as small and light as a conventional manual type.

In the gluing machine main body 1 of the present embodiment, a groove 34 is provided on the rear surface side of the lower structure 2 in the width direction of the apparatus, and the slitter 20 is detachably attached to the under stay 26 in the groove 34. I have. When the slitter 20 moves in the width direction in the groove 34, the ear P
Adjust the width of. The cross transport path of the slitter 20 is configured to extend along the rear side wall of the lower structure 2. For this reason, the rear side of the main body of the gluing machine has a structure in which a protective wall member 24 and an ear portion guide portion 25 to be described later slightly protrude, and the whole does not protrude outward. Then, the cross C unreeled from the web roll R

FIG. 2 is a structural view of the slitting presser stay 28 (constituting the presser stay of the present invention) and the tension bars 32 and 33 in the gluing machine according to the present embodiment as viewed from the rear of the gluing machine main body. is there. On the upper part of the leg 31, a first tension bar 32 is bridged over the entire width direction of the device, and both shaft ends are pivotally supported by a pivot member 38 so as to be rotatable around the axis. . An arm 35 is further rotatably attached to both shaft ends of the first tension bar 32 by a pivot member 38.
The arm portion 35 supports the rod-shaped slitter holding stay 28 in parallel with the first tension bar 32.
Thus, the slitter holding stay 28 is rotatable about the first tension bar 32. Further, since the length (width) of the slitter holding stay 28 is the width of the cross (the length in the direction orthogonal to the cross traveling direction), the entire width of the cloth C is held down by the slitter holding stay 28. Therefore, the meandering of the cloth C is prevented by the slitter holding stay 28.

FIG. 3A is a structural view showing a state in which the slitter holding stay 28 in the wallpaper gluing machine of the present embodiment is rotated upward, and FIG. 3B is a diagram showing a slitter holding stay.

As a result, the cutting of the ear portion P by the slitter 20 is ensured.

The fitting member 26 is attached to the main body 1 via a spring 34 as an elastic member of the present invention. For this reason, the elastic force from the spring 34 acts on the cross between the fitting member 26 and the main body 1 from the cross surface side to the back side. This elastic force is a pressure that does not prevent the cloth from being conveyed, so that wrinkles, bending, and the like can be suppressed while the cloth is smoothly conveyed.

The cross C is the first tension bar 3
Since the sheet C is conveyed while being given an appropriate tension via the second and second tension bars 33, wrinkles, deflections, and the like are generated in the cross C fed out from the raw material roll R by this and the slitter holding stay 28. This can be prevented more reliably.

In the gluing machine main body 1 configured as described above, the upper structure 3 is rotated with respect to the lower structure 2 to be in an open state, and is fed out from the raw roll R onto the slitter 20 and the lower structure 2. The cloth C is placed with its tip hanging down toward the front of the main body.

At this time, the slitting presser stay 28 is detached from the fitting member 36 and turned downward. Then, in this state, the cloth C is unwound from the material roll R, and
3B, and further as shown in FIG. 3B, the slitter 2 through a first tension bar 32.
If the cloth C is introduced into the main body through the inside of the main body 0, the initial setting can be easily performed without the slitter holding stay 28 being in the way.

Next, the holding stay 28 for the slitter is rotated upward to be fitted to the fitting member 36, and the cloth C is pressed down from the surface side. And the upper structure 3
Is closed, the lower structure 2 and the upper structure 3 as shown in FIG.
The cloth C is sandwiched between the predetermined rolls.

When the electric motor is driven in this state of holding the cloth, the rotation of the delivery roll 6 starts, and at the same time, the other rolls connected to the delivery roll 6 via the gears also start interlocking rotation. On the other hand, a slitter electric motor provided separately from the motor of the gluing machine main body is driven to rotate the rotary blade 23 of the slitter 20.

As a result, the cloth C is conveyed to the lower part of the slitter 20 with an appropriate tension via the second tension bar 33 and the first tension bar 32.
Then, on the main body wall surface below the slitter 20, the cloth C is pressed by the slitter holding stay 28 from the surface side to the full width, so that the cloth C is introduced vertically into the slitter 20 without any meandering, wrinkles and bending. To go. Then, while the cloth C is being conveyed to the gluing machine main body 1, the side edge portion is cut at a predetermined position by the contact of the slitter 20 with the rotary blade 23. The cut-off ears P are directed toward the outside of the slitter 20 along the guide portions 25 and fall downward, while the cut and adjusted cloth C body is glued over the entire back surface. The glue in the glue tub 4 is scooped up while being conveyed forward from the rear side of the machine body 1 while being transported forward, and reaches the rotating glue roll 8 while the amount of glue is adjusted by the doctor roll 7. Then, the glue is transferred from the gluing roll 8 to the back surface, and is sent from the front with the glue applied.

The pressing stay 28 for the slitter used in the automatic wallpaper gluing machine of the present embodiment is formed in the shape of a rod. The effects of the present invention can be achieved even with a shape.

In this embodiment, the present invention is applied to an automatic wallpaper sizing machine. However, the present invention can be applied to a manual wallpaper sizing machine in which cloth is transported manually.
