[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wallpaper sizing machine for continuously applying a paste to the back surface of a wall material in order to attach a sheet-like wall material (wallpaper) to an indoor wall surface. ,
In particular, the present invention relates to a structure of a tension bar that applies tension to a wall covering material supplied to an inlet.

[0002]

2. Description of the Related Art In general, sheet-like wall coverings (hereinafter referred to as "wallpaper") such as cloth, paper, and vinyl sheets are attached to indoor walls and ceilings. There are various types of such wallpaper (materials, etc.) that meet various demands, such as good design, dirt resistance, tear resistance, etc., for the purpose of being stuck on the indoor wall or ceiling, which is the stage of life. , Design, surface shape, etc.) have been proposed.

[0003] Generally, in order to paste the wallpaper onto the wall or ceiling in the room, it is necessary to paste the back of the wallpaper. At this time, the paste is applied to the back of the wallpaper using a wallpaper pasting machine. I have.

FIG. 5 shows a schematic configuration of a cross section of a conventionally used wallpaper sizing machine. This wallpaper gluing machine includes a main body 20 and a main body 2 for drawing and gluing the wallpaper.
FIG. 5 discloses a state in which the upper frame 1 of the main body 20 is opened for explanation, but FIG. 5 shows a state in which the upper frame 1 is glued to the wallpaper (cloth) 8. 1 is in a closed state.

[0005] Inside the main body 20, a glue tub 2 filled with glue, a pull-in roll 3a for drawing the cloth 8 into the main body,
3b, a gluing roll 4 for applying glue to the pulled-in cloth 8 and sending rolls 5a and 5b for sending out the glued cloth 8 are provided. Further, a control box 6 is provided on the outer surface of the upper frame 1. ing. A slitter 9 is provided on the side of the inlet outside the main body 20 to adjust the width of the cloth 8 from the cloth cloth 8a.

Each of the draw-in rolls 3a, 3b, the glue roll 4, and the delivery rolls 5a, 5b is driven by an electric motor (not shown), and the control box 6 controls on / off and the number of revolutions of the electric motor. ing. In addition, a manual type sizing machine that conveys wallpaper by an operation using a pulling force of a user from the front without using an electric motor has also been proposed.

The first tension bar 7a and the second tension bar 7 are disposed on the leg 30 in parallel with the glue roll 4.
b, and a cloth blank 8a around which the cloth 8 is wound. The two tension bars 7a and 7b provided on the leg portion 30 apply tension to the cloth 8 from the cloth cloth 8a to remove the meandering and wrinkles of the cloth 8 and to slit the cloth 8 in a tight state. 9.

In addition, depending on the type of the cloth 8, meandering and wrinkles cannot be removed unless a strong tension is applied.
Since meandering and wrinkles can be sufficiently removed without applying strong tension, in this conventional example, two tension bars are provided, and the tension bar is given to the cloth 8 by selecting a tension bar to be used according to the type of the cloth 8. Adjusts the intensity of tension.

For example, in the case of a cloth 8 which is sufficiently thin without applying a strong tension, the cloth 8 is hooked only on the first tension bar 7a as shown by a dotted line in FIG. In the case of No. 8, the cloth 8 is hooked on both the first tension bar 7a and the second tension bar 7b as shown by the solid line in FIG.

The cloth 8 from which meandering, wrinkles and the like have been removed by the tension bars 7a and 7b is adjusted in width by the slitter 9, and then introduced into the main body by the draw-in rolls 3a and 3b and sent to the gluing roll 4. . The cloth 8 transferred to the sizing roll 4 is transferred to the delivery rolls 5a and 5b via the sizing roll 4.
When the paste passes through the gluing roll 4, the glue is uniformly applied to the contact surface (the back side) with the gluing roll 4, so that the sending rolls 5a and 5b are provided with the cloth 8 in which the glue is uniformly applied to the back side. It is delivered and sent out of the main unit.

In general, in order to apply the paste uniformly on the back surface of the wallpaper, it is ideal to keep the wallpaper tight. As described above, the wallpaper sizing machine is provided with the tension bars 7a and 7b, and the tension (the tension) against the pulling force from the slitter 9 is obtained by hooking the wallpaper on the tension bars 7a and 7b. It is provided to the slitter 9 by giving the wallpaper a stretched wallpaper.

[0012]

However, depending on the material of the wallpaper, there are various types of wallpaper, such as a strong tension, a thick wall, and a surface with many irregularities. The above-mentioned wallpaper sizing machine directly attaches two tension bars to legs vertically extending from the main body, and applies tension by hooking the wallpaper to one or both of the two tension bars according to the type of wallpaper. Because of the configuration, the degree of application of tension is uniform, and depending on the type of wallpaper, there are difficulties such as excessive application of tension, and conversely, difficulty in application.

For example, there are many irregularities on the side in contact with the tension bar, and in the case of a thick wallpaper, the tension of the wallpaper itself and the frictional resistance with the tension bar are large, so that the wallpaper may be over-tensioned.

If the tension is applied to the wallpaper too much, the delivery of the wallpaper by the delivery roll becomes very slow, the glue adheres to the back surface of the wallpaper, or in the worst case, the wallpaper is torn or the delivery roll is damaged. Problems such as a failure of the delivery roll due to excessive load occur.

Conversely, in the case of a wallpaper having no unevenness on the side in contact with the tension bar and having a small frictional resistance between the tension bars, the tension is not sufficiently applied, and the wallpaper is wrinkled and wrinkled. There is a possibility that a problem may occur that the glue cannot be uniformly applied to the back surface of the wallpaper because the glue is applied and sent out in the state.

In view of the above, it is a main object of the present invention to provide a wallpaper sizing machine which can always supply an appropriate tension to the main body regardless of the type of wallpaper. . Another object of the present invention is to provide a wallpaper gluing machine that can freely adjust the size of the tension applied to the wallpaper.

[0017]

In order to solve the above problem, according to the first aspect of the present invention, a predetermined tension is applied to the wall covering by a tension bar disposed in a conveying path of the sheet-like wall covering. In a wallpaper gluing machine which draws in the inside of the main body and applies glue to the back surface of the wall covering by a gluing roll provided inside the main body, it is arranged at a position parallel to the tension bar in a transport path of the wall covering. The tension bar and the auxiliary bar by changing the position of the auxiliary bar by the fixed position variable unit. In both cases, the tension applied to the wall covering material is changed.

As described above, there are various types of wallpaper, such as a strong tension, a thick wall, and a large number of irregularities on the surface, depending on the type of the wallpaper. It varies depending on the target wallpaper.

Therefore, according to the first aspect of the present invention, in addition to the tension bar, an auxiliary bar parallel to the tension bar is provided in the transport path of the wall material as means for applying tension to the wall material, and the tension bar and the auxiliary member are provided. In addition to applying the tension to the wall covering material drawn into the gluing machine body by both the bar and the fixing position variable means that can change the fixing position of the auxiliary bar, according to the type of wallpaper to be glued By changing the fixing position of the auxiliary bar
The position of the auxiliary bar with respect to the inlet of the wall covering is changed to adjust the strength of the tension applied to the wall covering.

As such a fixed position changing means, for example, an auxiliary bar fixing means for directly attaching the auxiliary bar to the wallpaper gluing machine is provided, and the auxiliary bar fixing means changes the fixing position of the auxiliary bar itself. And a configuration in which the auxiliary bar is attached to the wallpaper pasting machine via an auxiliary bar holding means such as an arm member, and the mounting position of the auxiliary bar holding means is variably configured and / or the mounting position is centered. One that changes the fixed position of the auxiliary bar by being rotatable is exemplified.

The fixing means for directly attaching the auxiliary bar according to the present invention to the wallpaper gluing machine is not particularly limited as long as the auxiliary bar can be fixed at a plurality of different positions. Absent. Further, it is preferable that the change of the position of the auxiliary bar does not involve the removal of the auxiliary bar to facilitate the operation.

For example, an auxiliary bar may be attached to the wallpaper sizing machine by a holding means such as an arm member as a fixing means, and one end of each of a pair of arm members is attached to each of both ends of the auxiliary bar, The other end of each of the arm members may be attached and fixed to one of a leg portion, a main body portion, and a tension bar of the wallpaper gluing machine.

By using the arm member, the auxiliary bar can be fixed at a position separated from the main body or the leg by the length of the arm member. For this reason, since the transport route of the wallpaper can be changed significantly as compared with the related art, there is an advantage that the tension applied to the wallpaper can be greatly changed. The tension on the wallpaper can be changed by moving the arm to a different position on the main body or the leg.

Further, at the same mounting position, for example,
It is also conceivable to change the state of attachment such as rotating the arm around the attachment part and fixing it at a different angular position. In this case, the position of the auxiliary arm changes due to a change in the fixed angle of the arm, and the tension on the wallpaper can be changed.

Further, instead of making the fixed angle variable (or simultaneously), the arm member itself is made deformable, for example, by being configured to be extendable and contractible, and by adjusting the extension and contraction state of the arm member, the auxiliary bar can be adjusted. There is also a configuration in which the position is changed. Further, as another deformable configuration, it is possible to change the size of the tension applied to the wallpaper by changing the bent state of the arm member and fixing the arm member.

In any of the configurations, in the wallpaper gluing machine of the present invention, the fixing position of the auxiliary bar with respect to the main body of the gluing machine can be changed by the fixed position changing means. Therefore, the intensity of the tension applied to the wallpaper by both the tension bar and the auxiliary bar can be selected as appropriate according to the type of the wallpaper.

Further, since an auxiliary bar is provided in addition to the tension bar, a transport path using one or both of them can be considered. For this reason, it is possible to pass the wallpaper in multiple ways, so it is possible to roughly determine the degree of tension in advance according to the way the wallpaper passes, and then adjust the size of the tension by changing the fixing position of the auxiliary bar. is there. That is, according to the present invention, there is also an advantage that fine adjustment can be performed to the fixed position by the variable means after the tension on the wallpaper is temporarily determined in advance.

According to a second aspect of the present invention, in the wallpaper gluing machine according to the first aspect, the fixed position changing means has a pair of arm members respectively connected to both ends of the auxiliary bar. The fixing position of the auxiliary bar is changed by changing the fixing state of the arm member.

That is, the invention of claim 2 shows one of the preferred embodiments of the fixed position changing means, in which a pair of arm members for connecting both ends (including the vicinity of both ends) of the auxiliary bar are used. By changing the fixed state of the arm member, the position of the auxiliary bar connected to the arm member is changed, and the strength of the tension applied to the wallpaper is adjusted.

As a configuration for changing the fixed state of the arm member, for example, as shown in FIG. 1, the arm member is connected to a tension bar fixed to the gluing machine, and a connection portion between the tension bar and the arm member is provided. The arm member may be configured to be rotatable about the connecting portion as a fulcrum (with the longitudinal direction as an axis).

As another configuration, there is a configuration in which the strength of the tension is adjusted by changing the mounting position of the arm member to the gluing machine main body according to the type of wallpaper. Alternatively, the arm member may be directly attached to the leg portion, and at the attachment portion, the arm member may be rotatable around the longitudinal direction of the bar.

As described above, since the fixing state of the arm member is variable, the fixing position with respect to the gluing machine main body can be easily changed while the auxiliary bar is held in parallel with the tension bar. Can be easily adjusted. Further, if the fixing angle of the arm member with respect to the wallpaper sizing machine can be finely changed, fine adjustment of the magnitude of the tension can be performed.

The arm member and the auxiliary bar may be fixedly connected to each other, or the auxiliary bar may be connected to the arm member so as to be rotatable about its longitudinal axis. Needless to say.

According to a third aspect of the present invention, in the wallpaper sizing machine according to the second aspect, the arm member is connected to the tension bar, and the fixed position changing unit includes the arm By rotating the member about the longitudinal direction of the tension bar as an axis, the fixed position (fixed angle) of the arm member is changed, and the fixed position of the auxiliary bar is changed.

That is, in the wallpaper sizing machine of the present invention, since the tension bar and the auxiliary bar are provided as a means for applying tension, the strength of the tension applied to the wallpaper is determined with respect to the entrance of the wall material. It is determined by the positional relationship between the tension bar and the auxiliary bar. Therefore, the size of the tension applied to the wallpaper is changed by moving the auxiliary bar with respect to the entrance port of the wall covering material and the tension bar.

According to the third aspect of the present invention, the auxiliary bar is moved with respect to the inlet and the tension bar by rotating and fixing the arm member connected to the tension bar with the connection point as a fulcrum. . Thus, the position of the auxiliary bar is changed, so that it is possible to easily adjust the strength of the tension depending on the type of paper.

For example, in the case of gluing a thin wallpaper, as shown in FIG. 2A, the arm member 11b is set at a position that does not fall down too much (a position close to the main body or a position where the resistance is small at the time of conveyance) and is weak against the wallpaper. In the case where a tension is applied and thick wallpaper is glued, the arm member 11b is tilted down as shown in FIG. 2B (a position far from the main body or a position where a large resistance is applied at the time of conveyance) and a strong tension is applied to the wallpaper. Is given.

As described above, according to the present invention, the position of the auxiliary bar is changed to change the transport route of the wallpaper.
For example, the resistance is increased by changing the path to a position distant from the main body or the roll, or changing the bending angle of a bar in the path.

According to a fourth aspect of the present invention, in the wallpaper sizing machine according to the third aspect, the arm member is connected to the tension bar, and the connecting portion of the tension bar is a longitudinal member. A mounting portion having an outer shape of a regular polygonal prism having an axis in a direction, wherein the connecting portion of the arm member has a fitting portion having an inner diameter of a shape that fits the outer shape of the mounting portion; The position changing means changes the fixed state of the arm member by changing the fitting state of the fitting part of the arm member and the mounting part of the tension bar by rotating relative to the longitudinal axis. It is assumed.

In other words, according to the fourth aspect of the present invention, the arm member is attached to the tension bar by utilizing the fitting of the outer part having the shape of a regular polygonal column and the through part having the same inner diameter as the outer part. The configuration is simple because it is attached. Furthermore, since the mounting angle of the arm member with respect to the tension bar is determined according to the combined state of the fitting of the end portion of the arm member and the end portion of the tension bar, in order to change the mounting angle, It is only necessary to change the fitting state between the end of the arm member and the end of the tension bar, and the operation is simple.

That is, the combination of the irregularities of the regular polygon fits each other even when rotated by a predetermined angle. If this is used, the arm can be fixed at a plurality of different angles. The change can be made by simply removing the outer portion and the through portion, rotating them relative to each other by a predetermined angle, and fitting the outer portion and the through portion again, which is extremely simple.

Further, if the penetrating portion is made of a flexible material having a certain degree of strength and has a structure in which one surface or a part of the penetrating portion is cut off, the outer portion in the penetrating portion is aligned with the longitudinal axis. It is preferable because there is no trouble of detaching the outer portion from the through portion each time.

According to a fifth aspect of the present invention, in the wallpaper gluing machine according to the second aspect, the arm member is connected to the tension bar, and the fixed position changing unit is configured to control the tension. The fixed state of the auxiliary bar is changed by changing the fixed state of the bar.

That is, as described above, the strength of the tension in the wallpaper sizing machine of the present invention depends on the positional relationship between the tension bar and the auxiliary bar with respect to the inlet of the sizing machine main body (and the tension bar and the auxiliary bar). The size of the tension applied to the wallpaper is changed by moving the auxiliary bar with respect to the inlet and the tension bar.

According to the fifth aspect of the present invention, the fixed position changing means changes the fixed state of the tension bar,
The arm member fixed to the tension bar and the auxiliary bar fixed to the arm member are moved integrally, and as a result, the auxiliary bar is kept parallel to the tension bar, and The fixing position of the auxiliary bar with respect to the entrance is changed.

Here, changing the fixing state of the tension bar means that the mounting position of the tension bar itself is not changed or the mounting position of the tension bar is not changed.
For example, the operation includes changing the mounting state of the tension bar so that only the position of the auxiliary bar changes, such as rotating the tension bar at a desired angle about the longitudinal axis of the tension bar. .

With such a configuration, the position of the auxiliary bar with respect to the gluing machine main body can be easily changed, so that the size of the tension applied to the wallpaper can be easily adjusted according to the type of the wallpaper. Further, the fixing state of the tension bar may be finely changed such that, for example, when the tension bar is rotatable around the longitudinal direction as an axis, the tension bar can be fixed at a plurality of rotation (angle) positions. For example, fine adjustment of the magnitude of the tension can be performed.

Here, in the case where a conventional gluing machine has tension bar holding means for detachably attaching a tension bar to a gluing machine (main body or leg portion),
By using the auxiliary bar integrally formed with the tension bar, the present invention can be easily applied to a conventional device.

For example, a tension bar member which is arranged in the transport path of the sheet-like wall covering to the wallpaper sizing machine and applies a predetermined tension to the wall covering, and is provided in parallel with each other. A connecting member for connecting the bar members of
Attachment means configured to change the fixing position of the at least one bar member with respect to the wallpaper sizing machine may be considered.

In this tension bar member, the tension bar of the present invention and the auxiliary bar are integrally provided by a connecting member, and the means for attaching to the gluing machine (main body or leg) includes at least the attachment of the auxiliary bar. What is necessary is just to hold | maintain so that a position can be changed.

If such a tension bar member is used, the present invention can be applied to a conventional gluing machine by a simple modification or the like, and a gluing machine in which the tension applied to the wall covering can be easily changed can be obtained. it can.

For example, if the projections provided on the legs are fitted into and cut out from the notches provided at the ends of the tension bar members, the tension bar members may be provided with the projections of the legs. The present invention can be applied without changing the protruding portions by providing a plurality of cut portions for fitting the protruding portions and making the arrangement of the auxiliary bars different depending on the selection of these cut portions. An example is shown below.

In the invention according to claim 6, in the wallpaper gluing machine according to claim 5, the arm member is connected to the tension bar while being fixed to the tension bar.
The tension bar includes a cut portion at each of a plurality of angular positions in a plane orthogonal to the longitudinal direction, and the fixed position variable unit inserts one of the cut portions to fix the tension bar. The tension bar is changed to a fixed state at a different angular position by changing a cut portion into which the protrusion is inserted, and the fixing position of the auxiliary bar is changed together with the arm member. Shall do.

That is, according to the invention of claim 6, the tension bar is provided with notches provided at a plurality of angular positions in a plane orthogonal to the longitudinal direction, and the protrusion of the fixed position variable means has a plurality of notches. Since the configuration is such that the tension bar is fixed by being inserted into one of the parts, not only the configuration is simple, but also the advantage that the fixing state of the tension bar can be easily changed. . Further, by adopting such a configuration, the present invention can be easily incorporated into a conventional sizing machine, and there is also an advantage that cost is low and preferable.

Further, according to a seventh aspect of the present invention, in the wallpaper pasting machine according to the first aspect, the fixed position changing means has a pair of arm members respectively connected to both ends of the auxiliary bar, The arm member is configured to be deformable, and the fixing position of the auxiliary bar is changed by deforming the arm member.

That is, in the invention of claim 7, as the fixed position changing means, a pair of arm members which are connected to both ends (including the vicinity of both ends) of the auxiliary bar and are configured to be deformable are used. The position of the auxiliary bar with respect to the inlet of the gluing machine is changed according to the deformation state of the member, and the intensity of the tension applied to the wallpaper is adjusted.

Examples of such an arm member include a slide type, a bellows-like extendable member, a bendable member having a link structure, and a member that can be extended and contracted by a spring such as a spring. In addition, as a slide type, for example, a hollow tube having two different diameters configured so that one outer diameter matches the other inner diameter is used, and one hollow tube has an auxiliary bar at one end. While holding, the other end is inserted in the other hollow tube, and the position of the auxiliary bar is determined according to the inserted state.
It is needless to say that all of the configurations listed as the arm members are configured so that each can fix its own expansion / contraction or / and bending state at a desired position at a desired position.

As described above, since the arm member itself is configured to be deformable, the fixing position with respect to the main body of the sizing machine can be easily changed while the auxiliary bar is held in parallel with the tension bar. The size of the tension can be easily adjusted. Further, since the fixing position of the arm member with respect to the wallpaper gluing machine can be finely changed, fine adjustment of the tension can be performed.
