Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wallpaper pasting machine that continuously applies glue to the back surface of a long wall covering, for example, when a sheet-like wall covering is attached to an indoor wall surface. The present invention relates to a cutting device for cutting the side edge portion and adjusting the width to a predetermined width and then supplying it to a gluing machine, and a rotary blade built-in cartridge for the cutting device.
[0002]
[Prior art]
Conventionally, before applying the glue on the back of the long sheet-like wall covering drawn from the back of the wallpaper pasting machine and pulling it out from the front, it was attached to the main body of the wallpaper pasting machine with a hook etc. The side edge portion of the wall covering material is sheared in advance along the conveying direction by the wallpaper cutting device and adjusted to a desired wall covering width.
[0003]
A conventional wallpaper cutting device for a general wallpaper pasting machine has a pair of upper and lower one-sided blades facing each other at a position opposed to an upper and lower shaft provided parallel to the direction perpendicular to the conveying direction of the wall covering material. An overcutter (upper blade) and undercutter (lower blade) that make up the rotary blade are pivotally supported, and the pair of cutters are rotated reversely by the drive motor to shear the wall covering from above and below. Was.
[0004]
Alternatively, a single rotary blade of both blades is pivotally supported on a shaft, and the wall blade is sheared by rotating the rotary blade with a drive motor in a state where the blade tip is pressed from one side to the wall material to be conveyed.
[0005]
[Problems to be solved by the invention]
However, in such a conventional wallpaper cutting device, since the rotary blade is exposed to the outside, the operator can touch the rotary blade from the outside during work, and there is a problem that it is not safe. .
[0006]
In particular, when exchanging the rotary blade, it is necessary to remove the rotary blade by directly touching the rotary blade. At this time, there is a risk of injury by the operator touching the blade portion. Further, when exchanging the rotary blade, the rotary blade must be removed from the shaft or the rotating shaft of the motor, and there is a problem that the exchanging operation of the rotary blade is difficult.
[0007]
The present invention has been made in view of such problems, and by providing a protective wall around the blade portion of the rotary blade, a wallpaper pasting machine and a wallpaper cutting device excellent in safety are provided. Main purpose. Another object of the present invention is to provide a wallpaper pasting machine, a wallpaper cutting device, and a cartridge with a built-in rotary blade that can be easily replaced by making the rotary blade detachable together with the cartridge.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 is a wallpaper pasting machine that applies a paste to the back surface of a wall covering material while pulling the sheet-shaped wall covering material from the rear of the main body and pulling it from the front. In
A single rotary blade that cuts the side edge of the wall covering to be conveyed, a shaft that pivotally supports the rotary blade, a boss that fixes the rotary blade to the shaft, and a shaft that pivotally supports the rotary blade. A motor unit including a rotational drive means for driving,
The single rotary blade is cut from the back surface of the wall covering,
The rotary blade, the shaft, and the boss portion are housed in a rotary blade built-in cartridge,
The rotary blade built-in cartridge has a protective wall that surrounds the periphery of the blade portion of the rotary blade, and constitutes a wallpaper cutting device that is detachably integrated with the motor unit,
In a state where the single rotary blade is fixed, the boss portion is configured to be incapable of relative movement with the shaft,
The wallpaper cutting device is characterized in that it is hooked on the upper back of the pasting machine main body.
[0009]
In the present invention, the rotary blade, the shaft, and the boss portion are housed in a cartridge with a built-in rotary blade, and the cartridge has a protective wall that surrounds the blade portion of the rotary blade. It is impossible to touch the rotary blade from the outside. For this reason, it becomes possible to aim at safety without the risk of injury due to contact with the rotary blade.
[0010]
In the present invention, since the cartridge with a built-in rotary blade is detachable from the rotation driving means, the operator can remove the entire cartridge from the rotation driving means and replace the rotary blade without touching the rotary blade. For this reason, compared with the conventional apparatus which must remove a rotary blade directly from the rotating shaft of a rotation drive means, the exchange operation | work of a rotary blade becomes simple.
[0011]
The cartridge with a built-in rotary blade of the present invention can be attached to and detached from the rotation driving means, and the configuration is not particularly limited as long as a protective wall surrounding the periphery of the rotary blade is provided. For example, it is preferable to provide an opening for introducing wall covering material in a portion other than the protective wall.
[0012]
In addition, as a drive means of a rotary blade, the structure which connects the output rotary shaft of a small motor to the spindle of a rotary blade is mentioned as a simple thing. Alternatively, when the gluing machine is driven by an electric motor, the power can be used. The rotation direction of the blade may be opposite to the conveying direction of the wall covering material, but in this case, if the resistance friction of the wall covering material is large, it becomes difficult to maintain straight cutting at a relatively low speed rotation. . In particular, in the case of a manual gluing machine, since the meandering is likely to occur when the conveyance speed is not always constant, the conveyance direction of the wall covering and the rotation direction of the blade are preferably matched.
[0013]
Moreover, it is preferable to provide the guide plate which guide | induces the cut | disconnected wall covering material side edge part to a path | route different from the wall covering main body drawn in in the gluing machine main-body part in this invention. In this case, since the side edge portion of the cut wall covering material is avoided from being introduced into the gluing machine main body by the guide plate, the gluing machine can be prevented from being damaged.
[0014]
The rotary blade may be located on either the upper side (front side) or the lower side (back side) of the wall covering material. However, for example, the wall covering material made of vinyl chloride is relatively easily melted by the rotational frictional heat of the blade, and the cut portion may be roughened and roughened. Since such rough cutting appears mainly on the abutting side of the rotary blade, when cutting from the surface side, the rough portion will be exposed and noticeable when the wallpaper is later attached to the wall surface. It is more preferable to cut from the back surface, that is, from the lower side.
[0015]
In addition, the faster the rotation speed of the rotary blade, the easier it is to cut the wall covering. Therefore, the rotation speed can be increased according to the thickness and hardness of the target wall covering. It is desirable to provide a speed adjustment mechanism that can be changed to the above speed.
[0016]
The wallpaper pasting machine according to the present invention may be a so-called manual machine or an automatic machine using a driving force such as an electric motor.
[0017]
If the boss portion is configured to be relatively unmovable relative to the shaft in a state where the rotary blade is fixed to the boss portion, there is an advantage that shake when the rotary blade is rotated can be prevented. That is, in the conventional wallpaper cutting apparatus, as shown in FIG. 7A, the boss portion 704 to which the rotary blade 702 is attached is slid on the shaft 701, and the boss portion 704 is fixed to the shaft 701 by the fixing screw 703 at a desired position. The rotary blade 702 is positioned by being fixed to. For this reason, the inner diameter of the boss portion 704 is formed larger than the outer diameter of the shaft, and a gap exists between the boss portion 704 and the shaft 701. For this reason, as shown in FIG. 7B, when the boss portion 704 is fixed to the shaft 701 with the fixing screw 703, the rotary blade 702 is inclined and fixed to the shaft 701 (cannot be fixed vertically). In some cases, when the rotary blade 702 is rotated in this state, the rotary blade 702 swings to the left and right, and there is a problem in that the wall covering material side edge cannot be cut straight.
[0018]
If the boss part is configured so that it cannot move relative to the shaft with the rotary blade fixed, the state where the rotary blade is fixed vertically to the shaft can be maintained. Since the cartridge with the built-in rotary blade may be slid integrally with the rotary drive means, the rotary blade does not tilt as in the conventional apparatus. Therefore, even if the rotary blade is rotated, the rotary blade can be prevented from swinging left and right, and the wall covering material side edge portion can be cut straight.
[0019]
Further, a preferred wallpaper cutting device is configured to be detachable from the wallpaper pasting machine main body, and in the wallpaper cutting device that cuts the side edge of the wall covering along the conveying direction while conveying the sheet-like wall covering. a single rotary blade for cutting the wall covering to be, and is characterized in that and a protective wall which surrounds the blade portion around the rotary blade.
[0020]
In this wallpaper cutting apparatus , since the protective wall surrounding the periphery of the blade portion of the single rotary blade is provided, the operator cannot touch the rotary blade from the outside during work. For this reason, it becomes possible to aim at safety without the risk of injury due to contact with the rotary blade.
[0021]
This wallpaper cutting apparatus should just be provided with the protective wall surrounding the blade part periphery of a single rotary blade, and the structure is not specifically limited.
[0022]
A more preferable wallpaper cutting device is configured to be detachable from the wallpaper pasting machine main body, and in the wallpaper cutting device that cuts the side edge of the wall covering along the conveying direction while conveying the sheet-like wall covering. A single rotary blade for cutting the wall covering material, a shaft that pivotally supports the rotary blade, a boss portion that fixes the rotary blade to the shaft, and a rotation drive means that drives the rotary blade, The rotary blade, the shaft, and the boss portion are accommodated in a cartridge with a built-in rotary blade, and the cartridge with a built-in rotary blade has a protective wall that surrounds the periphery of the blade portion of the rotary blade, and the rotation driving unit. It is characterized by being detachable.
[0023]
This wallpaper cutting apparatus has the same function and effect as the first aspect of the invention. Moreover, since this wallpaper cutting device is detachable from the gluing machine main body, when it is necessary to adjust the width by cutting the side edge of the wall covering material supplied to the wallpaper gluing machine, the gluing machine Attach the cutting device to the main unit. On the other hand, when it is not necessary to cut the wall covering material or when the apparatus is transported, the handling is simple if the cutting apparatus is removed.
[0024]
