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. The present invention relates to a slitter for moving a pinch roller and a lower pinch roller in parallel in respective axial directions.

[0002]

2. Description of the Related Art Conventionally, in a general wallpaper sizing machine, for example, as shown in FIG. Wallpaper gluing machine main unit 10 that applies glue to the back side
0, the slitter 101 is attached with a hook 117 or the like,
Shearing the side edges of the wall covering 120 along its transport direction,
The desired wall covering width was adjusted.

As shown in a schematic configuration diagram of FIG. 4B, a conventional general slitter 101 for a wallpaper gluing machine includes an overcutter (upper blade) 102 supported by a short shaft 104 and a long cutter 102. It mainly includes a pair of upper and lower rotary blades, each of which includes an under cutter (lower blade) 103 supported by a shaft 105, a guide rail 106, and a spring stopper 107.

[0004] The overcutter 102 is of a round blade type and can slide on short shafts 104 separately mounted above both ends of the slitter 101, but is determined in accordance with a desired wall material width. After being positioned at the shearing portion, it is fixed on the short shaft 104 by tightening a set screw 102b attached to a boss 102a penetrating the overcutter 102.

The short shaft 104 has one end rotatably supported about a shaft via a bearing on a short shaft bracket 114 fixed inside the rear side plate 112 of the slitter 101, and the other end provided with a gear box 110. It is mounted above both ends of the slitter 101 while being housed therein.

On the other hand, the undercutter 103 is also a round blade type, and is fixed to a cutter set boss 108 by being bossed. Also, under cutter 103
Are the spring stopper 107 and the spring 10
9 is slidably supported on the long shaft 105. The spring stopper 7 is fixed on the long shaft 105 by tightening a set screw 107a attached thereto. The spring 109 is always urged toward the over cutter 102 by the elastic force of the spring 109 via the cutter set boss 108 from the other end of the held spring 109.

The long shaft 105 includes a slitter 10
1 is disposed at both lower ends of the slitter 10.
A long shaft bracket 115 fixed inside the front side plate 113 is rotatably supported about the axis. The long shaft 105 rotatably supports a guide roll 106 for feeding the wall covering material into the main body 100 of the gluing machine at the center.

[0008] Both ends of the long shaft 105 are accommodated in the gear box 110, but a gear is provided near the tip, and the gear is fitted to the gear provided at the tip of the short shaft 104 in the gear box 110. It is in. Accordingly, the rotation of the two gears causes the overcutter 1 via the short shaft 104 and the long shaft 105 to rotate.
02 and the upper and lower rotary blades of the under cutter 103 can be rotated in opposite directions while abutting each other.

Normally, in a state in which the slitter 101 is attached to the gluing machine main body 100 by the hook 117, the drive of the gluing machine is transmitted to transmit the gearbox 110.
A power transmission gear 118 for rotating the upper and lower rotary blades of the overcutter 102 and the undercutter 103 and the guide roll 106 via the internal gears is provided outside the front surface of the gear box 110.

In such a configuration, the gluing machine main body 1
A plurality of rolls on the 00 side are rotated by a motor, and a wall covering 120 is interposed between the overcutter 102 and the undercutter 103, which are interlockingly rotated via gears.
(At this time, both ears of the wall material are sheared), the wall material is pulled in to the front side in the gluing machine main body 100, the drive of the roll is stopped, and the initial setting of the gluing is performed. .

After the initial setting of the gluing is completed, when the plurality of rolls and the over cutter 102 and the under cutter 103 on the gluing machine main body 100 side are rotated by driving the motor, the wall covering 120 is glued through the slitter 101. While being conveyed into the attaching machine main body 100, the cloth has a desired cross width, the backside is coated in the main body 100, and the liner is drawn out from the front surface of the main body 100 while the liner is laminated on the paste application surface. Since the wall covering material on which the glue is continuously applied is drawn out, the wall covering material is cut every length corresponding to the height of the wall surface to which the wall covering material is stuck.

[0012]

In the conventional slitter for a wallpaper sizing machine as described above, first, in the sizing operation,
In order to shear the extra width dimension of the wall covering side edge to the desired cross width, visually check the scale of the scale plate 116 mounted at a position corresponding to the overcutter 102 on the outer surfaces of both ends of the slitter. Meanwhile, the overcutter 102 is moved on the short shaft 104 and the undercutter 103 is moved on the theoretical shaft 105, and is set at a position corresponding to a desired cross width.

The position setting of the two cutters is performed by setting the set bolt 1 screwed into the boss 102a fixing the over cutter 102 to the short shaft 104.
02b and loosen substantially undercutter 10
Set bolt 107 fixing the spring stopper 107 for positioning the third shaft 3 to the long shaft 105
a must be loosened.

By loosening both set bolts (102b, 107a), the overcutter 102 and the undercutter 103 can be slid on each shaft to desired positions. After the overcutter 102 and the undercutter 103 have been moved to the desired positions, the set bolts (102b, 107a) must be tightened again to fix the spring stopper 107 for positioning the overcutter 102 and the undercutter 103.

[0015] On the other hand, many wall coverings have various patterns and patterns.
It is desired that the pattern and the regularity of the pattern be continuous in the contact area between adjacent wall coverings. Therefore, the shear position of the wall covering material must be set not only to correspond to the cross width but also to a position in consideration of the pattern and the continuity of the pattern.

However, in the conventional slitter as described above, even if the position of the overcutter and the undercutter is finely adjusted according to the pattern of the wall covering material, both cutters are fixed to each shaft as described above. It is necessary to loosen the set bolt, move the cutter to a desired position, and re-tighten the set bolt to fix the cutter to the shaft. Moreover, this adjustment corresponds to the cutting position on the pattern of one side edge adjacent to the wall covering piece cut immediately before the wall covering piece cut to the length equivalent to the wall height. Must be done. This is very time and labor consuming and reduces work efficiency.

In view of the above problems, an object of the present invention is to obtain a slitter suitable for a wallpaper sizing machine. Another object of the present invention is to provide a slitter for a wallpaper sizing machine that can easily set a shearing position of a wall covering material by a rotary blade.

[0018]

According to a first aspect of the present invention, there is provided a slitter for a wallpaper sizing machine according to the first aspect of the present invention, wherein the sheet-like wall covering material drawn in from the rear is drawn out from the front. A wall-mounting machine that applies glue to the back surface of the wall covering, is detachably attached to a main body of the wallpaper pasting machine, has a pair of upper and lower rotating blades, and the side of the wall covering being conveyed with the rotation of the rotating blade. A slitter for a wallpaper gluing machine for shearing an edge portion along a transport direction thereof, comprising a moving means for moving the pair of rotary blades in parallel in an axial direction thereof, and a wall mounting by the pair of rotary blades by the moving means. The shear position of the material is adjusted to a desired position.

According to a second aspect of the present invention, in the slitter for a wallpaper gluing machine according to the first aspect of the present invention, the moving means comprises a pair of upper and lower rotating blades each having an axis. The upper shaft and the lower shaft to be supported are integrally moved in parallel in the axial direction.

The moving means in the present invention may be any means as long as the pair of upper and lower rotary blades for shearing the side edges of the wall covering material along the transport direction are simultaneously and integrally moved in the axial direction. By providing such a moving means, even after the wall covering is passed through the slitter, the pair of upper and lower rotating blades can be moved in parallel to a desired position by the moving means without loosening the bolts, respectively. The adjustment of the shearing position according to the pattern or pattern can be easily performed.

The parallel movement of the pair of rotary blades may be performed, for example, as described in claim 2, by an upper shaft (for the upper rotary blade) and a lower shaft (for the lower rotary blade) which respectively support the pair of upper and lower rotary blades. By simply moving the blade (for the blade) in parallel in the axial direction, it can be easily implemented. At this time, the pair of upper and lower rotary blades may be fixed to the shafts that support each other, so that the shearing position can be easily adjusted at any time according to the pattern or pattern of the wall covering. In other words, the moving means only needs to move each rotary blade fixed to the shaft in the axial direction together with the shaft.

In the slitter for the wallpaper sizing machine, both ears of the wall covering material are cut off in a desired width dimension by shearing.
Generally, a pair of upper and lower rotating blades is provided on both left and right sides of the slitter width direction corresponding to the width direction of the wall covering material. Therefore, for example, a first pair of upper and lower rotating blades for shearing one side edge of the wall covering material and the other side edge are sheared at the left and right ends of the upper and lower shafts over the entire left and right length in the slitter width direction. If the moving means is provided at least at one end of the upper and lower shafts, the moving means can be moved in parallel in the axial direction of the upper and lower shafts. Accordingly, the first and second pair of upper and lower rotating blades can be easily moved to a desired position while maintaining a mutual interval while both are fixed to the shaft.

A first upper and lower shaft for supporting a pair of first upper and lower rotary blades on both left and right sides of the slitter;
When the second upper and lower shafts for supporting the pair of second upper and lower rotary blades are separately installed, the first
For moving the upper and lower shafts in parallel in the axial direction.
And a second moving means for moving the second upper and lower shafts in parallel in the axial direction thereof.

In this case, the first pair of upper and lower rotating blades can be easily moved to a desired position with the first upper and lower rotating blades fixed to the shaft in accordance with the parallel movement of the first upper and lower shafts by the first moving means. In addition, the second pair of upper and lower rotating blades can be easily moved to a desired position while being fixed to the shaft with the parallel movement of the second upper and lower shafts by the second moving means.

As the moving means for moving the upper and lower shafts in parallel in the axial direction, for example, a means using a male screw and a female screw or a means using a gear can be mentioned as a simple and inexpensive structure. In addition, the present invention is not limited to this. For example, in a slitter for a wallpaper sizing machine according to the present invention, such as an electric reciprocating plunger or a fluid pressure cylinder, any mechanism capable of moving the upper and lower shafts in the axial direction from the end side can be used. is there. However, these mechanisms must be designed to be driven without hindering the rotation of the upper and lower shafts about the axis.

When the pair of upper and lower rotary blades are not supported by the shaft, the moving means may be configured to move the mounting means for mounting the rotary blade on the slitter body in the width direction.

(First Embodiment) As one embodiment of the present invention, a first pair of upper and lower rotary blades and a second pair of upper and lower rotary blades are provided on both left and right sides of an upper and lower shaft over the entire left and right length in the slitter width direction. FIG. 1 shows a slitter for a wallpaper sizing machine, which is rotatably supported and has moving means for moving the upper and lower shafts in parallel in the axial direction at one end of the upper and lower shafts.

As shown in the schematic configuration diagram of FIG. 1A, the slitter for a wallpaper gluing machine according to the present embodiment has a slitter body 1 having a width direction corresponding to the width direction of the wall covering material to be sheared. Upper shaft 4 and lower shaft 5 over the entire left and right length
Are arranged respectively. That is, the upper shaft 4 has gearboxes (10a, 1a) on both sides of the slitter body 1 at both ends.
0b), and is rotatably supported on the upper bracket 14 fixed to the upper inner side surface of the rear surface of the main body 1 via a bearing so as to be rotatable about the central axis and slidable in the axial direction. The shaft 5 is housed in the gearboxes (10a, 10b) at both ends below the upper shaft 4, and is rotated about a substantially axial center via a bearing on a lower bracket 15 fixed to the lower inner surface on the front surface of the main body 1. And is slidably supported in the axial direction.

On both sides of the upper shaft 4, a round blade type over cutter 2 a and an over cutter 2 b are respectively slidably supported on the upper shaft 4. Each overcutter (2a, 2b) is provided with the overcutter (2a, 2b).
a, 2b) Set bolts (7a, 7) which are set screws which are attached to bosses (6a, 6b) formed respectively.
b) is fixed on the upper shaft 4 by tightening.

On both sides of the lower shaft 5, a round blade type under cutter 3a and an under cutter 3b are provided.
Each of the cutter set bosses (11a, 11b) is screwed and fixed to the cutter set boss (11a, 11b).
And is slidably supported on the lower shaft 5. The lower shaft 5 further includes one under cutter 3a.
A spring Sa, one end of which is in contact with the other via a cutter set boss 11a, and a spring stopper 8a, which holds the other end of the spring Sa, are slidably supported by the shaft, respectively. A spring Sb, one end of which is in contact via
A spring stopper 8b for holding the other end of the spring Sb is slidably supported on each shaft.

Both spring stoppers (8a, 8b)
Are fixed to the lower shaft 5 by tightening set bolts (9a, 9b). Therefore, when both spring stoppers (8a, 8b) are fixed, the undercutter 3a and the undercutter 3b are always over-cuttered via the cutter set bosses (11a, 11b) by the elastic force of the springs (Sa, Sb), respectively. 2a and the overcutter 2b are urged, and are substantially positioned and fixed on the lower shaft 5.

As described above, in the slitter according to the present embodiment, one side edge of the wall material is sheared by the overcutter 2a and the undercutter 3a which are pivotally supported at one end of the upper and lower shafts (4, 5). And a pair of upper and lower rotary blades, and an overcutter 2b and an undercutter 3 supported on the other end of the shaft (4, 5).
b constitutes a second pair of upper and lower rotary blades for shearing the other side edge.

In the slitter according to the present embodiment,
A guide roll 16 is rotatably supported at the center of the lower shaft 5 at a central portion thereof so as to smoothly feed the wall covering material to be conveyed to the main body of the gluing machine. In order to prevent the conveyed wall covering material from bending on the guide roll 16, a tension board 17 for pressing the wall covering material on the guide roll 16 is provided.

In both gear boxes (10a, 10b), gears 19 are fixed on both sides of the upper shaft 4 and gears 20 are fixed on both sides of the lower shaft 5, respectively. Gear 19 and gear 2 on both sides
0 is fitted. Therefore, as described later, when the driving of the gluing machine is transmitted to the gear 20 via the transmission gear 30 in a state where the slitter is attached to the body of the gluing machine, the gear 2
0, the lower shaft 5 rotates, the gear 19 fitted to the gear 20 also rotates in the opposite direction, and the upper shaft 4 also rotates.

In one gear box 10a,
A moving means for integrally moving the upper shaft 4 and the lower shaft 5 in parallel in the axial direction is provided. this is,
As shown in a partial perspective view of the inside of the gear box 10a of FIG. 1B from the rear side, and a side view of FIG. 1C and a cross-sectional view of FIG. An operating screw 21 having a male screw part parallel to the axial direction of the shaft 4 and the lower shaft 5, a female screw part 22 a to be fitted in the gear box 10 a with the male screw part of the operating screw 21, and an extension of the upper shaft 4. This is a mechanism including an interlocking bush 22 that integrally supports the tip of the extension shaft 5x of the shaft 4x and the lower shaft 5.

The operation screw 21 is rotatably supported by the box cover with its head out of the gear box cover 10a, and a thrust washer 26 in the direction of the rotation axis.
And a lock nut 27. An operation knob 21a is fixed to the head of the operation screw 21 so as to cover the lock nut 27 and the washer 26. The operating nut 21 can be displaced in the axial direction by loosening the lock nut 27 with a special jig from the gap below the operation knob 21a and rotating the operation knob 21a in that state, and tightening the lock nut 27 with the special jig. By doing so, the axial displacement of the operation screw 21 can be fixed. Further, the thrust washer 26 applies a spring force between the gear box 10a and the operation screw 21 via the lock nut 27, and the operation screw 2 for the gear box cover 10a.
An axial thrust force is applied to the support 1 to prevent rattling. When it is desired to reduce the rotational thrust load acting on the interlocking bush 22 by turning the operation screw 21 by turning the operation knob 21a, the extension shafts 4x and 5x of the upper and lower shafts inserted through the interlocking bush 22 are used. May be further extended to penetrate the gear box cover 10a slidably in the axial direction. In this way, the upper and lower shafts (4, 5) are rotatably supported on the interlocking bush 22 while being rotatable and not relatively moving in the axial direction.
When the interlocking bush 22 is displaced in the axial direction, the upper and lower shafts 4 and 5 are also displaced in the axial direction together.

Accordingly, when the operating screw 21 is rotated by the operating knob 21a, the interlocking bush 22, in which the female screw portion 22a is screwed with the male screw portion of the operating screw 21, moves in the axial direction, and accordingly moves up and down. The shafts (4, 5) move in parallel with the interlocking bush 22 in the axial direction. In such a moving mechanism, the moving direction and the moving amount of the upper and lower shafts (4, 5) are determined by the rotating direction and the rotating amount of the operation knob 21a, so that the positioning of the upper and lower rotary blades can be adjusted. As a guide for this purpose, appropriate scales, arrows, and the like may be displayed on the operation knob and the gear box cover around the operation knob.

The shearing operation of the wall covering in the slitter having the above configuration will be described below. First, the upper cutter 2a is loosened by loosening the set bolts (7a, 7b).
And 2b can be freely moved on the upper shaft 4, and by loosening the set bolts (9a, 9b), the spring stoppers (8a, 8b) can be used together with the springs (Sa, S).
b), the cutter set bosses (11a, 11b) and the lower cutters (3a, 3b) are freely movable on the lower shaft 5.

Scale plates 18a and 18b having graduations are provided at positions corresponding to the upper cutters 2a and 2b on the outer surfaces of both ends of the rear portion of the slitter main body 1, respectively. The upper cutters 2a and 2b are respectively moved to the positions where the cross widths are equal to each other. After positioning, each boss (6
The upper cutters (2a, 2b) are fixed to the upper shaft 4 by tightening the set bolts (7a, 7b) into the upper shaft 4 (a, 6b). At this time, the interval between the upper cutters 2a and 2b is a distance corresponding to a desired cross width.

Hooks 3 are provided on both sides of the front of the slitter body 1.
2 is provided, and the slitter body 1 is attached to the gluing machine by hooking the hook 31 on the stay on the side of the wallpaper gluing machine body as in the case shown in FIG. 2 (a). A plurality of rolls on the gluing machine main body side are rotationally driven by a motor, and this is interlocked with a gear 20 via a power transmission gear 30 and is rotated together with the gear 19.

The upper shaft 4 and the lower shaft 5 also rotate with the rotation of the gears 19 and 20, and the upper cutter 2a and the lower cutter 3 as a first pair of upper and lower rotary blades.
a, upper cutter 2b as a second pair of upper and lower rotary blades
The lower cutter 3b and the lower cutter 3b rotate inward each other while keeping the cutting edges in sliding contact with each other.

When the tip of the wall covering material is inserted from the rear side of the slitter body 1 between the first and second pair of upper and lower rotating blades rotating as described above, the rotation of both rotating blades and the guide roll 16 The wall material is fed from the rear side to the front side by the rotation. At this time, the wall covering is made up of the upper cutter (2a, 2b) and the lower cutter (3
According to a and 3b), both ears are sheared so as to have a desired cross width. The wall material sent out through both rotating blades is drawn in to the front side of the gluing machine main body, the driving of the roll is stopped, and the initial setting of the gluing is performed.

The operator cuts off the end portion of the wall covering material that has not been glued, sets a desired cross length in accordance with the height of the wall surface to which the wall covering material is attached, and completes the initial setting of the gluing. When the initial setting of the gluing is completed, the driving of the motor is started again, and the upper and lower shafts (4, 5) on the side of the slitter main body 1 and the gears (3, 5) together with the plural rolls in the main body of the gluing machine.
0, 19, 20) to rotate the first vertically rotating blade (upper cutter 2a, lower cutter 3a) and the second vertically rotating blade (upper cutter 2b, lower cutter 3b).

As a result, the wall covering material is conveyed into the sizing machine main body while being sheared to a desired cross width, and the backside is coated with glue in the sizing machine main body and sent out to the front surface of the main body. When the desired cross length comes to the front, the drive of the motor is temporarily stopped and cut as the first wall covering piece.

Next, before resuming operation of the motor, one of the next sheared wall coverings, which will be next to one side edge of the first wall covering piece, for example here Then the first
The first rotary blade (upper cutter 2a, lower cutter 3a) is positioned at the side edge on the upper and lower rotary blade side so that the first rotary blade (upper cutter 2a, lower cutter 3a) comes to the pattern position corresponding to the shear position on the pattern of the first wall covering piece. The operating knob 21a on the head of the operating screw 21 protruding out of the gearbox 10 of the main body is rotated to operate the interlocking bush 22 and the vertical shaft extension shaft (4x, 5).
The position adjustment is performed by integrally moving the upper shaft 4 and the lower shaft 5 in the axial direction via x). In this position adjustment operation, as described above, the lock nut 27 is rotated by a special jig to release the fixing of the operation screw 21 and after the adjustment is completed, it is tightened and locked again. The exclusive jig was used to cover the lock nut 27 with the operation knob 21a.
This is to prevent erroneous operations by non-specialized workers.
Needless to say, if it is not necessary, the lock nut 27 may be always exposed so that the lock nut 27 can be operated with a normal spanner.

When the position adjustment is completed, the driving of the motor is restarted. The wall covering material is transported into the sizing machine main body while having a desired cross width and the first upper and lower rotary blade sides are sheared at a desired pattern position, and the back surface is coated with the glue in the sizing machine main body. To the front of the main unit. When the desired cross length comes to the front, the drive of the motor is temporarily stopped, and cut as a second wall covering piece.

Next, at the pattern position that matches the shear position on the pattern on the side edge of the second wall covering piece that has been sheared by the second vertically rotating blades (upper cutter 2b, lower cutter 3b). The position of the upper shaft 4 and the lower shaft 5 is moved in parallel in the axial direction by rotating the operation knob 21 a via the interlocking bush 22 so that the first rotary blade comes.

After the position adjustment, the motor driving is resumed, and the third piece of wall covering obtained by gluing and shearing at the desired cross length has the desired cross width and is cut by the first vertical rotary blade. The sheared side edge is sheared at a position on the pattern that coincides with the side edge of the second adjacent wall covering piece. The operator repeats this operation.

As described above, in the slitter for a wallpaper sizing machine according to the present embodiment, the adjustment of the shearing position on the pattern of each wall covering piece to be cut to a desired cross length requires complicated labor and time. And can be easily performed.

A spring stopper 48b for holding the other end of the shaft b is slidably supported on each shaft.

The spring stopper 48b is fixed to the second lower shaft 45b by tightening a set bolt similarly to the first lower shaft 45a. Therefore, when the spring stopper 48b is fixed, the second
The lower cutter 43b is always urged toward the second overcutter 42b via the cutter set boss 51b by the elastic force of the spring 46b, and substantially the second
Is fixed to the lower shaft 45 on the upper b.

As described above, in the slitter according to the present embodiment, one of the wall coverings is formed by the first upper cutter 42a and the first lower cutter 43a supported by the first upper and lower shafts (44a, 45a). A first pair of upper and lower rotating blades for shearing the side edges of the first and second upper cutters 42b and the second lower cutters 43b are supported by second upper and lower shafts (44b, 45b). A second pair of upper and lower rotary blades for shearing the other side edge is thereby configured.

Here, the guide roll 56 for smoothly feeding the wall covering material into the main body of the gluing machine is rotatable from both sides by mutually facing ends of the first lower shaft 45a and the second lower shaft 45b. Both lower shafts (45a, 45b) are supported by guide rolls 5
6 can be moved in the axial direction without affecting the rotation. Further, a tension board 47 for pressing the wall covering material on the guide roll 56 is also mounted so as to be rotatable in the vertical direction.

In both gearboxes (50a, 50b), first and second upper shafts (44a, 44b) are provided.
A gear is fixed to each end of b), and a gear fitted to the gear on the upper shaft side is fixed to the ends of the first and second lower shafts (45a, 45b). With the two gears on the lower shaft side, the drive of the gluing machine is transmitted via the transmission gear 30a and the transmission gear 70b in a state where the slitter is attached to the gluing machine main body, and the rotation of these gears First upper and lower shafts (44a, 45a)
And the second upper and lower shafts (44b, 45b) rotate at the same speed, and the first pair of upper and lower rotary blades and the second pair of upper and lower rotary blades also rotate at the same speed on both left and right sides of the slitter body 41. .

Further, both gear boxes (50a, 50
In b), the first upper and lower shafts (44
a, 45a) in the axial direction, and a second moving mechanism in the second vertical shaft (44b, 45b) in the axial direction. The structure of the first and second moving mechanisms is shown in FIGS. 1B and 1C provided in the slitter according to the first embodiment.
This is similar to that shown in (d). That is, mainly
It has an operating screw with a male screw part whose longitudinal direction is parallel to the axial direction of the upper and lower shafts, and a female screw part that fits with the male screw part of the operating screw in the gearbox cover, and has an upper shaft extension shaft and a lower shaft extension shaft. This is a mechanism composed of an interlocking bush that rotatably supports the distal end portion so as to be incapable of relative movement in the axial direction.

Therefore, when the operation knob (not shown) projecting out of the gear box cover 50a is rotated,
The interlocking bush (not shown) moves in the axial direction in accordance with the rotation of the operation screw (not shown), and the vertical shaft (4
4a, 45a) integrally translate in the axial direction. Therefore, only by rotating the operation knob, the first pair of upper and lower rotating blades fixed to the first upper and lower shafts (44a, 45a) move in the width direction of the slitter main body 41, so that the first vertical A pair of rotary blades (the first upper cutter 42
a) Fine adjustment of the shearing position by the first lower cutter 43a) can be easily performed.

When another operating knob 61 projecting out of the gear box 50b is turned, an interlocking bush (not shown) is turned on in response to the turning of the operating screw (not shown).
Moves in the axial direction, and accordingly, the upper and lower shafts (44
b, 45b) integrally translate in the axial direction. Accordingly, the second pair of upper and lower rotating blades fixed to the second upper and lower shafts (44b, 45b) move in the width direction of the slitter main body 41 only by rotating the operation knob 61, so that the second A pair of upper and lower rotary blades (second upper cutter 4
2b, the fine adjustment of the shearing position by the second lower cutter 43b) can be easily performed.

When the slitter having the above configuration is mounted on the main body of the wallpaper gluing machine and the wall covering material is conveyed into the main body of the gluing machine while being sheared to a desired cross width, the glue is applied from the initial setting. The process is the same as that of the above-described first embodiment until the first wall covering piece that is sent out to the front surface of the gluing machine main body and cut at a desired cross length is obtained.

In the slitter for a wallpaper gluing machine according to the present embodiment, in the adjustment of the shearing position to be performed before the driving of the motor of the gluing machine main body is resumed, first, the side adjacent to the first wall covering piece and the side next to the first wall covering piece In this case, the position of the rotary blade for shearing the side edge portion of the first rotary cutter, for example, the first upper and lower rotary blades (the first upper cutter 42a and the first lower cutter 43a) is adjusted on the pattern.

That is, the first vertical shaft (44a, 45a) is moved in parallel by rotating the head knob outside the box 50a while visually checking the scale of the scale plate 42a, whereby the first vertical rotary blade is moved. Move to the desired position. After the adjustment of the position of the first vertical rotating blade on the pattern is completed, the head knob 61 is rotated while visually checking the scale of the scale plate 42b, and the second vertical shaft (44b, 45b) is parallelized. By moving, the second vertically rotating blade is moved to a position at an interval corresponding to a desired cross width with respect to the first vertically rotating blade.

After the adjustment of the positions of the first and second upper and lower rotary blades on the pattern is completed, the driving of the motor is restarted to obtain the second wall covering piece. Thereafter, the operator repeats the same operation, so that the wall covering pieces whose adjacent edge patterns match each other are sequentially obtained from the gluing machine body when pasted on the wall surface.

It should be noted that, as shown in the first embodiment,
In a slitter for a wallpaper sizing machine having a configuration in which first and second upper and lower rotary blades are pivotally supported on both sides of the same upper and lower shafts, both rotary blades are maintained while maintaining an interval between the first and second upper and lower rotary blades. Can be adjusted at the same time, so that the position adjustment for each wall covering piece is simple and trouble-free.

On the other hand, the first embodiment shown as the second embodiment
The first vertical shaft supporting the vertical rotating blades of the first and second vertical shafts supporting the second vertical rotating blades are separately provided, and the first vertical shaft is moved by the first moving mechanism to the second vertical shaft. In the slitter for a wallpaper gluing machine configured to move the second upper and lower shafts in parallel by the moving mechanism of (1), the first upper and lower rotary blades and the second upper and lower rotary blades must be moved, respectively. Since the interval between the blades can be changed arbitrarily, not only the position adjustment on the pattern but also the setting of the cross width can be performed while each rotary blade is fixed to the shaft, so that the efficiency of the entire operation is high.

As described above, in the first and second embodiments, as the moving means for moving the upper shaft and the lower shaft in parallel in the axial direction, the mechanism using the feed screw system by screwing the male screw and the female screw is shown. However, the moving means in the present invention is not limited to this, and can be widely used as long as the upper and lower shafts can move in parallel in the axial direction. Also,
It is preferable that the fine adjustment of the positioning of the upper and lower shafts (upper and lower rotary blades) be simpler.

For example, one using a combination of a rack and a pinion is conceivable. That is, as shown in the schematic configuration diagram of FIG. 3A, a rack member 82 formed with a rack gear 83 arranged on the axial extension of the upper shaft 4 and a rack gear 84 arranged on the axial extension of the lower shaft 5, and a rack gear 82 83
Shaft member 8 provided coaxially with an upper pinion gear 85 meshing with the lower pinion gear 86 meshing with the rack gear 84
7 and a rotation operation section 81 attached to the upper end of the rotation shaft member 87 outside the gear box 80.

When the rotary operation portion 81 is rotated, the upper pinion gear 85 and the lower pinion gear 86 rotate in the same direction with the rotation of the rotary shaft member 87, and mesh with the upper and lower pinion gears (85, 86). The rack member 82 is driven by the upper and lower pinion gears (85, 8)
6) linearly move in the direction corresponding to the rotation direction. In accordance with the movement of the rack member 82, the upper shaft 4 and the lower shaft 5 move together with the gears 19 and 20 in the axial direction in parallel. The rack member 82 is provided with a gear (19,
20) and the upper and lower shafts (4, 5) without being hindered from rotating. Is possible.

The moving means using the rack and pinion method is similar to the moving means using the feed screw method, in which first and second vertical rotating blades are provided on both sides of the same vertical shaft. In a slitter for a wallpaper gluing machine having a supported configuration, a first vertical shaft supporting a first vertical rotary blade and a second vertical shaft supporting a second vertical rotary blade are separately installed. It is needless to say that a slitter for a wallpaper gluing machine can be used.
