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 glue to the back surface of a long wall material when, for example, attaching a sheet-like wall material to an indoor wall surface. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wallpaper cutting device for cutting a side edge portion of a wall material and adjusting the width to a predetermined width, and supplying the wallpaper material. About.

[0002]

2. Description of the Related Art Conventionally, when a paste is applied to the back side of a long sheet-like wall covering by a wallpaper pasting machine, a wallpaper cutting device is attached to the wallpaper pasting machine with a hook or the like, and the wall covering is cut off. The side edges are cut along the transport direction. Specifically, first, the cover of the wallpaper cutting device attached to the gluing machine is opened, and the wall covering is set inside. Then, after driving the drive motor to rotate the rotary blade at high speed, the wall covering material is pulled out from the front of the gluing machine main body. At this time, the rotating wall blade that rotates at a high speed is pressed against the wall covering material conveyed from the back side,
The side edges of the wall covering are cut off. When the gluing operation is completed, the drive motor of the wallpaper cutting device is stopped.

[0003]

However, in the conventional wallpaper cutting apparatus, an operator must manually start a drive motor to rotate the rotary blade at a high speed, and stop the rotation of the rotary blade. Therefore, the operator must manually stop the drive motor. For this reason, there is a problem that the gluing operation becomes complicated.

[0004] Further, once the drive motor is started, even if the transport of the wall covering is stopped or interrupted, the drive motor is always driven until the drive motor is stopped, so that power consumption is wasted. It has become something.

The present invention has been made in view of the above problems, and provides a wallpaper cutting device capable of reducing the labor for gluing work by automatically controlling the driving of a rotary blade. The main purpose is to Another object of the present invention is to provide a wallpaper sizing machine that can reduce power consumption.

[0006]

In order to achieve the above object, according to the first aspect of the present invention, a side edge portion of a wall covering is cut while a sheet-like wall covering is conveyed to a wallpaper sizing machine. In the wallpaper cutting device, a rotary blade that cuts a side edge of the wall covering material along the transport direction, and a driving unit that rotationally drives the rotary blade,
A roll that rotates in accordance with the conveyance of the wall covering, a detecting unit that detects an axial rotation of the roll and generates an output signal, and an output signal from the detecting unit is input, and based on the output signal, Control means for controlling the driving of the driving means.

In the present invention, since the roll rotates in accordance with the transport of the wall covering, if the roll is rotating, the wall covering is being transported. If the roll is not rotating, the wall covering is in progress. The lumber has stopped. The rotation of the roll shaft is detected by the detection means, and an output signal is input to the control means. The control means performs drive control of the drive means based on the output signal, and performs rotary drive control of the rotary blade.

As described above, according to the present invention, the conveyance of the wall covering is automatically detected, and the start and stop of the driving means can be controlled automatically. It is not necessary to stop the driving of the driving means when the transfer of the wall covering is stopped, and the labor for the gluing operation is reduced. In addition, since the driving unit can be driven only during the transfer of the wall covering, power consumption can be reduced.

The configuration of the detecting means is not particularly limited as long as it can detect the rotation of the roll shaft. For example, an output signal is always generated during the rotation of the roll shaft, and the start and stop of the rotation of the roll can be detected, respectively, so that the output signal can be generated only at the start and stop of the rotation.

The roll of the present invention may be any type as long as it rotates around the axis following the transport of the wall covering. As an example of such a roll, the wall covering is pinched from above and below and sent to a wallpaper gluing machine. One pair of pinch rolls can be used. In this case, since the detection means only needs to know the transport of the wall covering material, the detection means only needs to detect the axial rotation of one roll.

The control means only needs to drive the drive means when an output signal is output from the detection means. The control means drives the drive means while the output signal is being output, and outputs the output signal. The drive of the drive means can be configured to stop when it runs out. Further, if the detection means generates an output signal only at the start and stop of the rotation of the roll shaft, the drive means is driven by the signal at the start, and the drive of the drive means is stopped by the output signal at the stop. Can be configured.

According to a second aspect of the present invention, in the wallpaper cutting device according to the first aspect, the detecting means is provided at a shaft end of the roll, and detects a pulse signal while detecting rotation of the roll. And the control means activates the driving means when an output signal from the detection means is switched from the steady state to the pulse signal,
When the output signal switches from the pulse signal to a steady state, the driving of the driving means is stopped.

In the present invention, since the detecting means is provided at the end of the roll shaft, the rotation of the roll shaft end is detected to detect the rotation of the roll shaft, and a pulse signal is output during the rotation of the roll shaft. Output.

The control means receives an output signal from the detection means. This output signal is output while the roll is rotating.
A pulse signal that repeats ON-OFF at regular intervals,
When the roll is not rotating, it is in a steady state. Here, the “steady state of the output signal” is a state in which the output signal is not a pulse signal, and no output signal is input.
In addition to the state in which the FF state is maintained, the state in which the output signal is maintained in the ON state for a certain period is also included.

[0015] As an example, the detecting means is a disk member provided with a plurality of slits provided at the end of the roll shaft, and a light emitting element and a light receiving element arranged with the disk member interposed therebetween to detect light passing through the slit. Consider a case in which a pulse signal is output by detection.

If the disc member is at a position where the light from the light emitting element is blocked while the roll is stopped, no output signal is input to the control means. It continues as an OFF state. In this state, when the roll starts to rotate, the pulse signal is input from the detecting means, and the output signal input to the control means is switched from OFF to ON.
The FF is repeated at regular intervals (it becomes a pulse signal). Then, when the output signal is switched from the OFF state to the ON state at the start of the pulse signal, the control unit activates the driving unit.

On the other hand, when the disc member is at the position where the light from the light emitting element passes through the slit while the roll is stopped, the output signal to the control means remains ON, and accordingly, the output The “steady state of the signal” continues as the ON state. In this state, when the roll starts rotating,
A pulse signal is input from the detection means, and an output signal input to the control means is switched from ON to OFF, and thereafter ON-OFF is repeated at regular intervals during the rotation of the roll shaft (a pulse signal). Then, when the output signal is switched from the steady state to the OFF state at the start of the pulse signal, the control unit activates the driving unit.

If the disk member is located at a position where light is blocked from the light emitting element when the roll during rotation of the shaft is stopped,
The output signal is OFF and continues. The OFF state is a steady state, and when the last ON state of the pulse signal is switched to the steady state of the output signal OFF, the control unit stops driving the driving unit. Here, the control means outputs an output signal within the time of the pulse interval (time interval of each pulse).
When it does not change from FF to ON, it is determined that the state has been switched from the state of the pulse signal to the steady state.

On the other hand, if the disk member is at a position where light from the light emitting element passes through the slit when the roll during rotation of the shaft is stopped, the output signal is ON and continues. In this case, this state is a steady state, and when the last OFF state of the pulse signal is switched to the steady state of the output signal ON, the control unit stops driving the driving unit. Here, when the output signal does not change from ON to OFF within the pulse interval (time interval of each pulse), the control unit determines that the state of the pulse signal has been switched to the steady state.

As described above, in the present invention, the driving means is driven while the pulse signal is being output from the detecting means. Therefore, the driving means can be driven to rotate the rotary blade only while the wall covering is being conveyed. it can. For this reason, since the driving means is not driven while the wall covering is not being conveyed, power consumption can be reduced.

In the present invention, since the detecting means outputs a pulse signal during the rotation of the roll shaft, the control means counts the number of pulses of the input pulse signal to determine the feed length of the conveyed wall material. It is also possible to measure the length.

1 is a side perspective view showing a schematic configuration of a manual wallpaper gluing machine in a state where the present cutting device is attached.

The cutting apparatus 1 according to the present embodiment cuts the side edge 12 of the cloth 11 while conveying a wall covering material (hereinafter referred to as a "cloth") while being attached to the main body of the manual gluing machine. Things. Note that the cutting device of the present embodiment may be attached to an automatic wallpaper sizing machine that automatically carries the cloth.

As shown in FIG. 1, the cutting apparatus 1 of the present embodiment
Are two thin plate-shaped rotary blades 7 for cutting the side edges 12 on both sides of the cloth 11 along the transport direction, a small motor M for driving the rotary blades 7 to rotate, and a pair of upper and lower pinch rolls 3.
a, 3b, a pinch pressure adjuster 15 for adjusting the pinch pressure of the pinch roll, a disk 33 and a photosensor 35 for detecting the rotation of the pinch roll 3b, and the cut side edge 12 to the outside of the apparatus. A guide plate 8 for leading out is mainly provided. FIG. 2 is a schematic diagram showing the configuration near the axial ends of the pinch rolls 3a and 3b. The photosensor 35 is connected to a control unit 36 that constitutes control means of the present invention. It is connected.

The cutting device 1 of the present embodiment is detachable from the sizing machine, and can be attached to the sizing machine by hooking the locking portion 9 of the cutting device 1 to the hook 32 on the back of the sizing machine. It has become.

The cutting device 1 of this embodiment has a cloth 11
Are provided so as to face each other in the width direction, and the facing side plates are an upper side plate 13a and a lower side plate 1 respectively.
3b. As shown in FIG. 1, the both side plates are supported by a shaft support 14, and the upper side plate 13 is
a is rotatable with respect to the lower side plate 13b. That is, the upper side plate 13a and the lower side plate 13b are rotated by rotating the upper side plate 13a
Is in an open state. FIG. 1 shows a state in which the upper side plate 13a and the lower side plate 13b are closed.

The small motor M constitutes the driving means of the present invention. The small motor M is provided with a set bolt (not shown) on a stay 4a extending parallel to the width direction of the cloth 11 (a direction orthogonal to the conveying direction). ) Is provided via a mounting boss 4b which is fixed in the above manner.

The rotary blade 7 has a support shaft of the rotary blade 7 coaxially fixed to the rotary output shaft 5 parallel to the width direction of the small motor M. Therefore, the rotation of the small blade M is controlled by the driving of the small motor M. The power is transmitted to the rotary blade 7 via the output shaft 5, and the rotary blade 7 is rotationally driven at a predetermined rotation speed.

The rotary blade 7 is positioned at a position higher than a straight line connecting a contact portion on the stay 4a, which is a transport path of the cloth 11 transported through the cutting device, to a drawing portion into the gluing machine main body. It is set so that the top (edge) comes. This is because the rotary blade 7 pushes the cloth 11 conveyed in the cutting device from below (the rear surface side) to a position where the pushing force acts. By providing the rotary blade 7 at this position, the cloth 11 that slides on the rotary blade 7 is conveyed to the gluing machine 20 while being cut by the pressing force and the high-speed rotation of the rotary blade 7.

The mounting boss 4b for fixing the small motor M to the stay 4a is slidable along the stay 4a in the width direction when the set bolt is loosened. , The small motor M can be fixed. Thus, the small motor M can be positioned so that the rotary blade 7 comes to a cutting position corresponding to a desired cutting width of the cloth 11.

In the present embodiment, two rotary blades 7 facing each other in the cross width direction are provided. However, the rotary blade 7 for cutting one side edge 12 is shown in FIG. The effect of the present invention can be achieved even if the configuration is composed of only the individual components.
Further, in the present embodiment, the rotary blade 7 is pressed from the back side of the cloth 11 to cut the side edge portion 12, but a pair of upper and lower rotary blades is provided, and the rotary blade 7 is rotated while sandwiching the cross between the rotary blades. You may make it cut | disconnect a part.

The pair of upper and lower pinch rolls 3a, 3b are for sending out to the sizing machine main body while holding the cloth 11 drawn into the cutting device 1, and the aluminum upper rolls 3a which come into contact with each other without the cloth. And a rubber lower roll 3b. The materials of the upper roll 3a and the lower roll 3b are not particularly limited.

Each roll is disposed upstream of the cloth 11 in the conveying direction, that is, on the right side of the rotary blade 7 in FIG. The upper roll 3a is connected to the upper side plates 13 on both sides.
The lower roll 3b is pivotally supported by a shaft 6b which is fixed to the lower side plate 13b on both sides by a shaft end. For this reason, the upper side plate 13
When the roller a is rotated upward and opened, the upper roll 3a and the lower roll 3b are separated from each other, and the cloth 11 can be introduced between the rolls. On the other hand, when the upper side plate 13a and the lower side plate 13b are closed as shown in FIG. 1, the introduced cloth 11 is held between the upper roll 3a and the lower roll 3b.

When the worker pulls out the cloth 11 from the gluing machine main body, the cloth 11 is conveyed in the direction of arrow B, and the upper roll 3a holds the cloth 11 while holding the cloth 11 in FIG.
, The lower roll 3b rotates counterclockwise. For this reason, the cloth 11 can be pulled out straight, whereby the rotary blade 7 allows the cloth side edge 12 to be pulled out.
Can be cut linearly.

As shown in FIG. 2, near the roll shaft end,
A photosensor 35 having a pair of opposing surfaces is provided, and a light emitting element and a light receiving element for receiving light emitted from the light emitting element are provided on each of the opposing surfaces.

Also, one shaft end of the lower roll 3b has
A disk 33 having a plurality of slits 34 is attached, and the disk 33 is disposed between a pair of opposing surfaces of the photosensor 35 so that the slits 34 can pass therethrough. Therefore, when the slit 34 is located in the optical path from the light emitting element to the light receiving element due to the rotation of the disk 33,
The light emitted from the light emitting element passes through the slit 34 and is received by the light receiving element. On the other hand, when the slit 34 is not located in the optical path from the light emitting element to the light receiving element, the light emitted from the light emitting element is blocked by the disk 33. The disk 33 and the photo sensor 35 constitute the detecting means of the present invention.

When the pair of rolls rotates while the cloth 11 is conveyed, the disk 33 also rotates with the rotation, so that the rotation of the lower roll 3b can be detected by counting the slit passing through the light receiving element of the photo sensor 35. When a passing slit is detected, pulses corresponding to the number of passing slits are generated. Therefore, the number of passing slits counted is output to the control unit 36 as a pulse signal during rotation of the lower roll.

FIG. 3 is a block diagram showing the arrangement of the control unit 36 from the photo sensor 35.
FIG. 4 is an explanatory diagram showing a relationship between an output signal input to the control unit and a drive signal for driving a small motor M by a control unit 36. FIG. 3A shows a position where the disk 33 blocks light from the light emitting element (a position not passing through the slit 34) when the conveyance of the cloth 11 is completed or temporarily stopped and the rotation of the lower roll 3b is stopped. 4) shows the relationship between the pulse signal and the drive signal when stopping.

When the disk 33 stops at such a position, the light from the light emitting element is shut off, so that no output signal is input from the photo sensor 35 to the control unit 36, and therefore, the output signal in the control unit 36 is kept stationary. The state is the OFF state. That is, in FIG. 3A, the states of [1], [3], and [5] are steady states of the output signal OFF, and the states of [2] and [4] indicate that the output signal is a pulse. It is a signal state.

In the case of an output signal as shown in FIG. 3 (a), the output signal is switched from the steady state [1] to the pulse signal state.
The point A rises to the first ON state of [2] and the point C rises from the steady state [3] of the output signal OFF to the first ON state of the pulse signal state [4], that is, switches from the steady state to the pulse signal state. At this point, the control unit 36 turns on the drive signal to the motor M. Thereby, the rotary blade 7 is driven to rotate.

On the other hand, when the output signal falls from the last ON state of the pulse signal state [2] to the OFF state of the steady state [3], the output signal changes from the last ON state of the pulse signal state [4] to the steady state. The output signal does not change from OFF to ON within the pulse interval (time interval of each pulse) from each time point of the time point D1 at which the state changes to the OFF state [5]. For this reason, the control unit 36 determines that the output signal has been switched from the pulse signal state to the steady state at the time points B1 and D1, and outputs the drive signal to the motor M at the time points B2 and D2.
Set to FF. As a result, the rotation of the rotary blade 7 stops.

FIG. 3B shows a position where the disk 33 blocks the light from the light emitting element when the conveyance of the cloth 11 is completed or temporarily stopped and the rotation of the lower roll 3b is stopped (at the slit 34). The relationship between the pulse signal and the drive signal is shown in the case where the stop is at a position where the light is not passed through the slit 33 and the case where the stop is made at the position where the disk 33 passes the light from the light emitting element through the slit 34.

When the disk 33 stops at a position where the light from the light emitting element is blocked (a position where the light does not pass through the slit 34), the steady state of the output signal of the control unit 36 is changed as in FIG. It turns off. That is, in FIG. 3B, the states of [6] and [10] are steady states in which the output signal is OFF. On the other hand, the steady state of [8] is a case where the disc 33 is stopped at a position where the light from the light emitting element passes through the slit 34, and at this time, the light from the light emitting element passes through the slit 34. Since the light is received by the light receiving element, the output signal is in a steady state of ON.

Each of the states [7] and [9] is a state where the output signal is a pulse signal. In the case of the output signal as shown in FIG. 3B, the time point E at which the output signal from the photo sensor 35 rises from the steady state [6] to the first ON state of the pulse signal state [7], and the output signal At the time point G when the steady state [8] is turned on to the first OFF state of the pulse signal state [9], that is, when the steady state is switched to the pulse signal, the control unit 36 turns on the drive signal to the motor M. . Thereby, the rotary blade 7 is driven to rotate.

On the other hand, the output signal does not change from ON to OFF within a pulse interval from time F1 when the output signal rises from the last OFF state of the pulse signal state [7] to the ON state of the steady state [8]. Further, the output signal does not change from OFF to ON within a pulse interval from the time H1 when the pulse signal state [9] is finally turned on from the last ON state to the OFF state in the steady state [10]. Therefore, the control unit 36 determines that the output signal has been switched from the pulse signal state to the steady state at the time points F1 and H1, and turns off the drive signal to the motor M at the time points F2 and H2. As a result, the rotation of the rotary blade 7 stops.

As described above, the photo sensor 35 and the control unit 36
, The conveyance of the cloth 11 is automatically detected to automatically drive and stop the small motor M. Therefore, the operator drives the small motor M every time the conveyance of the cloth 11 is started, stopped, and restarted. There is no need to stop or stop, and the work effort is reduced. Further, the control unit 36 drives the small motor M only when the output signal is in the pulse signal state, in other words, when the cloth 11 is moving during the conveyance, the small motor M is not driven while the conveyance is stopped. , Power consumption is reduced.

In this embodiment, the disk 33 is attached to the shaft end of the lower roll 3b. However, the disk 33 is attached to the shaft end of the upper roll 3a, and the photo sensor 3 is located at a position corresponding to the disk.
Needless to say, the same effect can be obtained even if 5 is arranged.

In this embodiment, the rotation of the roll shaft is detected by the disk 33 attached to the end of the roll shaft and the photo sensor 35 sandwiching the disk. , And the rotation encoder may detect the rotation of the roll shaft.

In the present embodiment, the rotation of the lower roll 3b is determined by the presence or absence of the pulse signal input by the control unit 36. However, by counting the number of pulses of the input pulse signal, the cross 11 May be measured.

The pinch pressure adjusting section 15 adjusts the pinch pressure of the upper roll 3a and the lower roll 3b, and the pinch pressure is adjusted by increasing or decreasing the pressing force on the lower roll 3b of the upper roll 3a. .

The pinch pressure adjusting portions 15 are provided on the shaft ends on both sides of the upper roll 3a, respectively, and as shown in FIG. 1, the bearing bush 18 of the shaft 6a is fitted with the bearing bush 18 to be integrated. A supporting member 19b, a spring 16 for urging the bearing bush 18 from above, and a hexagon socket head bolt 17 for adjusting the urging force of the spring 16
a, a nut 17b screwed to the bolt 17a, and a plate-like member 19a supporting the nut 17b.

By rotating and tightening the bolt 17a, the elastic force of the spring 16 causes the bearing bush 18 to rotate.
, The pinch pressure of the upper roll 3a and the lower roll 3b increases. On the other hand, by rotating the bolt 17a in the reverse direction, the urging force of the spring 16 against the bearing bush 18 is reduced, and the pinch pressure of the upper roll 3a and the lower roll 3b is reduced.
Here, the bolt 17a is fixed to the plate member 19a by a nut 17b so as not to be loosened after adjusting the pinch pressure.

The guide plate 8 is attached to the frame of the small motor M so as to cover the upper part of the rotary blade 7.
And bulges upward and curves so as to have a substantially arc-shaped cross section along the shape of. For this reason, by this guide plate 8,
The side edge 12 of the cloth 11 is led out to a different path from the cloth 11 main body drawn into the gluing machine main body.

Next, a manual wallpaper gluing machine to which the cutting device 1 of the present embodiment is attached will be described. This manual gluing machine 2
Reference numeral 0 denotes a structure in which an operator glues the cloth back surface while manually pulling out the cloth 11, and is composed of an upper structure 21 and a lower structure 22 having a glue tub 23 therein. ), A plurality of rolls are arranged via gears.

As shown in FIG. 4, the main body of the sizing machine 20 is provided with a cloth 11 which is taken into the sizing machine main body from the rear side as a main roll in the upper structure 21, and is provided in front of the sizing machine main body. 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 the glue roll 26.
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 portion 12 is cut by the cutting device 1 and the cloth 11 adjusted to a predetermined width is glued, first, as described above, the engaging portion 9 is hooked by the hook 3 of the gluing machine 20.
The upper side plate 13a of the cutting device 1 is opened in a state where the cutting device 1 is hooked. Then, loosen the set bolt and install the boss 4b.
Is slid in the width direction of the cloth along the stay 4a. By tightening the set bolt at a position where the cloth has a desired cutting width, the rotary blade 7 and the small motor M are positioned.

Next, the tip of the cloth is pulled out from the raw cloth 10 pivotally supported by the cross receiving bracket 31 extending rearward from the sizing machine leg 30, and is drawn into the apparatus from the back side of the wallpaper cutting apparatus 1. It is pulled out from the front of the device by passing over the lower roll 3b and the rotary blade 7. afterwards,
The upper side plate 13a is closed, and the cloth 11 is held between the upper roll 3a and the lower roll 3b. If necessary, the pinch pressures at both shaft ends of the upper roll 3a and the lower roll 3b are individually adjusted at the respective shaft ends of the upper roll 3a as described above.

Then, the tip of the cloth 11 pulled out from the front of the cutting device 1 is placed on the lower structure 23 so as to hang from the front of the main body of the gluing machine 20 with the upper structure 21 opened. Then, the upper structure 21 is closed to obtain an initial setting state sandwiched between predetermined rolls.

After the completion of the initial setting, the drive of the drive source motor (not shown) of the gluing machine is started. Then, the operator manually pulls out the cloth 11 from the front of the gluing machine main body. As a result, the pinch rolls 3a and 3b rotate. The rotation of the shaft is detected by the photo sensor 35, and a pulse signal is output to the control unit 36. As described above, when the input of the pulse signal is started, the control unit 36 drives the small motor M, so that the rotary blade automatically rotates at a high speed.

Thus, the cutting of the side edge 12 by the rotation of the rotary blade 7 accompanying the passage of the cloth 11 through the cutting device,
The sizing of the cloth 11 after the width adjustment by the cutting in the main body of the sizing machine 20 is continuously performed.

When the conveyance of the cloth 11 is temporarily interrupted or the conveyance is completed, the rotation of the pinch rolls 3a and 3b is also stopped. Therefore, the input of the pulse signal from the photo sensor 35 to the control unit 36 is stopped, and the driving of the small motor M is stopped. Therefore, the rotation of the rotary blade 7 also stops automatically.

In this embodiment, the case where a separate cutting device is attached to the manual wallpaper gluing machine has been described. However, the rotary blade 7, the pair of upper and lower pinch rolls 3a and 3b, the photo sensor 35, and the control unit 36 are glued. It is good also as a structure provided integrally with a machine.

Further, in this embodiment, the case where the cutting device is attached to the manual gluing machine is shown, but the cloth is mainly transported manually and the driving source such as a motor assists the manual pulling out of the cloth. The effects of the present invention can be achieved even if the cutting device is attached to a sizing machine or an automatic wallpaper sizing machine that automatically carries a cloth.
