Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic wallpaper gluing machine for continuously applying a glue to the back of a sheet-like wall covering material to be attached to an indoor wall or the like. The present invention relates to a device provided with a wallpaper cutting device to be mounted on a device.

[0002]

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

[0003] As a general configuration of such a wallpaper sizing machine, a sizing machine main body mainly composed of an upper structure and a lower structure in which a plurality of rolls are arranged is mounted on a supporting leg. Then, while conveying the sheet-shaped wall covering material (hereinafter referred to as a cloth) sandwiched between the upper and lower structures by a roll, the glue is transferred from the glue tub to the back surface of the wall covering material by a gluing roller.

[0004] For example, in a manual gluing machine, a glue tub is installed in a lower structure, and a feed roll constituting a pinch roll for taking in a cloth from the rear side into the gluing machine body, and a glue tub in the glue tub. A gluing roll that transfers and applies the glue to the back of the cloth, a doctor roll that contacts the gluing roll and adjusts the amount of glue, and a leveling roll that applies an appropriate tension to the cloth and sends out the cloth in the front direction are connected to each other via a gear. The upper structure is attached to the lower structure so as to be openable and closable with the side plate of the glue tub or a bearing plate parallel thereto so as to be interlocked and arranged in parallel with a predetermined interval. In the inside, an upper pinch roll forming a pinch roll paired with the delivery roll, and a roll and a gear arranged in a lower structure are interlocked via a gear to form a cross in front of the gluing machine main body. A drive roll for applying a feeding tension in the direction, and a holding stay or a holding roll for holding the cloth from above between the upper pinch roll and the drive roll are arranged in parallel at a predetermined interval from each other. Each is supported by a bearing frame on both sides of the main body of the upper structure. Usually, the upper pinch roll has a function as a measuring roll for measuring the cross conveyance length.

[0005] When the cloth fed out from the raw fabric roll is placed on the lower structure as described above with the front end thereof hanging down in front of the main body and the upper structure is closed, the cloth is formed between the predetermined rolls of the lower structure and the upper structure. It is sandwiched. In this state of holding the cloth, if the tip of the cloth is pulled forward, the rolls sandwiching the cloth up and down follow and rotate, and the rolls rotate interlockingly via gears. As a result, the cloth is transferred from the back of the gluing machine body to the front, and when the cloth reaches the glue roll which is pulling up the glue in the glue tub by rotation during the rotation, the glue is transferred from the glue roll to the back surface. , And is sent from the front with the glue applied.

[0006] Recently, automatic sizing machines have also become widespread. In this automatic type, the rotation shaft of a drive mechanism such as a motor is connected to the end of the rotation shaft of the gluing roll, and the other rolls are interlocked via a gear by rotating the gluing roll electrically, and the rotation of these rolls The cloth is automatically transported. In this case, since the drive mechanism is connected to the gluing roll, the glue is not scooped up directly from the glue tub by the gluing roll and transferred to the back of the cloth, but the glue is scooped up and transferred to the gluing roll. Rolls are provided separately.

[0007] In an automatic sizing machine,
Generally, a cutting device for cutting a side edge portion of a cloth to adjust the width to a desired width is detachably mounted. In this cutting device, a pair of upper and lower rotating blades rotating in opposite directions are supported by respective shafts, and the pair of rotating blades moves on a rotating shaft to perform cutting positioning, and a cross between the upper and lower rotating blades is provided. The sheet is conveyed while being sandwiched, so that the side edge of the cloth is cut, and the cut cloth is sent to the gluing machine main body from behind.

[0008]

However, in the conventional automatic wallpaper sizing machine as described above, not only the sizing roll is additionally arranged, but also the sizing roll is located below the sizing roll on both sides of the sizing roll. Other rolls, including the lower solid glue roll, are located above the glue roll because they are supported by the wall, and the size and weight of the lower structure are larger than those of the manual type. It was inevitable.

The rotation of the pair of upper and lower rotary blades of the cutting device is performed by rotating the rotary shafts which support the pair of rotary blades and which are interlocked with each other via gears. These rotating shafts are configured so that a rotating motion based on a driving mechanism such as a front motor from the gluing machine body in the mounted state is transmitted to the gears and can rotate.

Therefore, as a driving source, not only the rotation of the conventional roll on the sizing machine main body side but also the load for interlocking rotation of the increased sizing roll, and a pair of upper and lower for cutting with the cloth interposed therebetween. It is necessary to mount a large-sized motor having relatively large power to allow the rotation load of the rotary blade, and the gluing machine is further increased in size and weight.

Similar to the manual type, such an automatic sizing machine also carries the sizing operation to the cloth at the site, so it is transported to the site, assembled there, and transported again after the operation is completed. Must be stored. The automatic type is desirable from the point of view of labor and work efficiency of workers, but the current automatic type is not suitable in consideration of the burden of transporting large and important equipment and the occupancy of storage when compared to the manual type. Is enough.

In view of the above problems, it is an object of the present invention to reduce the size and weight of the apparatus as compared with the conventional manual type, and to make handling and storage easier than the conventional automatic type. Another object of the present invention is to provide a compact and lightweight automatic wallpaper sizing machine.

[0013]

In order to achieve the above object, an automatic wallpaper sizing machine according to the present invention is characterized in that the sheet-like wall covering drawn in from the rear portion is sent forward and the wall covering is provided. A sizing machine body for continuously applying the sizing to the back surface of the sizing machine, and a side edge portion of the wall covering material detachably attached to the sizing machine body and conveyed to the sizing machine body. In an automatic wallpaper sizing machine having a wallpaper cutting device, the sizing machine main body includes a lower structure in which a glue tub storing the glue is installed, and an upper structure installed to be openable and closable with respect to the lower structure. In the lower structure, a delivery roll constituting a pinch roll for taking in the wall covering material from the rear side into the gluing machine main body, and transferring and applying the paste in the glue tub to the back surface of the wall covering material. To adjust the amount of glue in contact with the glue roll The glue tub so that a doctor roll and a leveling roll for applying an appropriate tension to the wall covering material and sending it out to the front can be interlocked with each other via gears and arranged in parallel at a predetermined interval. Side plate or a bearing plate parallel to the side plate, and in the upper structure, an upper pinch roll forming a pinch roll paired with the delivery roll, and arranged in the lower structure. A drive roll interlocked with a roll and a gear to apply a sending tension toward the front of the sizing machine body to the wall covering, and the wall covering is lifted between the upper pinch roll and the drive roll. The pressing stays or the pressing rolls to be pressed from are each supported by a bearing frame on both sides of the main body of the upper structure so as to be arranged in parallel at a predetermined interval, and the delivery roll is Rotationally driven by a drive mechanism at the same time as being rotatably driven via a hinge supported on the glue tub so as to be detachable and rotatable, and rotated by the drive mechanism on another roll interlocked via a gear. And a hinge supply opening to the glue tub is formed by rotating the hinge or removing the hinge together with the hinge. The wallpaper cutting device covers the upper portion of the device over the entire width direction and is transported. A guide plate that constitutes a stay portion on which the wall covering slides in a tensioned state, and is installed on the path of the wall covering from below the cutting device toward the guide plate so that the rotation direction is along the vertical direction. And a single rotary blade.

According to a second aspect of the present invention, there is provided an automatic wallpaper sizing machine according to the first aspect, wherein the rotary blade is configured to cut the wallpaper together with a shaft which supports the rotary blade. The cartridge is built in a cartridge with a built-in rotary blade that is detachably attached to the device. The cartridge with a built-in rotary blade is such that the shaft is linked to the drive mechanism or a rotary blade drive unit separate from the drive mechanism when the device is mounted. The rotary blade built-in cartridge covers a blade portion of the rotary blade that is exposed to the outside of the wallpaper cutting device, and includes a protective wall member that guides an ear separated from the wall covering material toward the inside of the device. It is characterized by having.

According to a third aspect of the present invention, there is provided an automatic wallpaper sizing machine according to the first aspect, wherein the wall covering is rotatably mounted on a rear portion of the sizing machine main body. It is fed out from the supported material roll via a tension bar bridged below a leg supporting the gluing machine main body, and a support shaft of the material roll is substantially vertically below the tension bar. It is characterized by being installed at a directional position.

Further, a wallpaper cutting device according to a fourth aspect of the present invention is a wallpaper cutting device detachably mounted on an automatic wallpaper sizing machine, which covers an upper portion of the device over the entire width direction and is conveyed. Plate that constitutes a stay that slides over the wall covering in tension and a wall covering that goes from below the cutting device to above the guide so that the rotation direction runs vertically. And one of the rotating blades.

The wallpaper cutting device according to a fifth aspect of the present invention is the wallpaper cutting device according to the fourth aspect, wherein the rotary blade and the shaft supporting the rotary blade are connected to the wallpaper cutting device. It is built into a cartridge with a built-in rotating blade that is detachably attached.
When the apparatus is mounted, the shaft is interlocked with the drive mechanism or a rotary blade drive unit separate from the drive mechanism, and the rotary blade built-in cartridge is exposed outside the wallpaper cutting device of the rotary blade. And a protective wall member that covers the side blade portion and guides the ear portion separated from the wall covering material toward the inside of the device.

In the automatic wallpaper sizing machine according to the first aspect of the present invention, the delivery roll is connected to the drive mechanism to transmit the rotational motion, and the sizing roll is separately provided as in the conventional manual type. Since the glue roll directly scoops the paste from the paste tub and transfers the paste to the back of the cloth without providing, there is no increase in the size and weight of the lower structure.

Further, in the wallpaper cutting device mounted on the automatic wallpaper sizing machine of the present invention, the guide plate covering the upper portion of the device over the entire width direction abuts over the entire width direction in a state where the conveyed cloth is in a tension state. To function as a stay that slides while
Since the entire cloth slides on the guide plate and passes, the cloth is unlikely to be wrinkled, and stable conveyance is performed.

Further, as described above, this cutting device is installed on the path of the cloth going from below the wallpaper cutting device to above the guide plate so that the rotation direction is along the vertical direction. Since the rotary blade is hit at the position where the blade edge is pressed against the back side, the side edge of the cloth is cut smoothly and vertically while being conveyed. As described above, in the present cutting apparatus, it is not necessary to perform cutting while transporting between a pair of upper and lower rotating blades as in the related art, and the cutting of the cloth proceeds easily only by contact with one rotating blade.

The load for rotating one rotary blade is:
Since the load for rotating the pair of rotary blades is greatly reduced as compared with the load for rotating the pair of rotary blades in the related art, the driving source for rotating the rotary blades requires only a small power. Therefore, when the rotational motion of the drive mechanism of the gluing machine main body is used as the drive source, the load on the drive mechanism is reduced, and a small-sized device having a smaller power than the conventional one is sufficient. In addition, since a small driving power is required only for rotating the rotary blade, it is possible to mount a dedicated driving unit separate from the gluing machine main body on the wallpaper gluing machine. In this case, the load on the drive mechanism of the gluing machine body is further reduced.

As described above, the automatic wallpaper sizing machine of the present invention conforms to the conventional basic structure of a manual type, and can avoid an increase in the number of rolls of the lower structure and an accompanying increase in size, and a drive source. Since only a small device is required, it is possible to provide a lightweight and easy-to-handle automatic wallpaper sizing machine in which the entire apparatus is prevented from becoming large and heavy.

In the arrangement of the rotary blade of the wallpaper cutting device as described above, the blade portion is exposed to the outside, and there is a danger that an operator may touch the device from the outside and get injured. It is preferable to provide a protective wall member that covers the blade portion on the side where the blade is located. As a configuration for providing a protective wall member, for example,
As described in claim 2, if the rotary blade is incorporated in a rotary blade built-in cartridge detachably attached to the cutting device together with the shaft, and the cartridge is provided with a protective wall member, when the rotary blade is replaced, Since the whole cartridge can be removed, there is no danger of injury by touching the blade directly with the hand as compared with a case where only the rotary blade is removed from the shaft, so that safety is further improved.

When the cartridge with a built-in rotary blade is mounted on the wallpaper cutting device, a shaft, which is a rotary shaft for supporting the rotary blade, transmits a rotary motion from a drive mechanism on the main body side of the gluing machine. It is assumed that the driving mechanism is connected to a rotating shaft of a rotating blade driving means which is separate from the driving mechanism. In addition, if the protective wall member is provided so that the ears separated from the cloth are guided toward the inside of the apparatus, the ears are well separated from the cloth body conveyed to the upper side of the apparatus (on the guide plate), and the glue is provided. It is avoided that it gets into the attached machine body.

Further, the delivery roll in the present invention comprises:
Since it is pivotally supported via a hinge that is detachably and rotatably supported on the glue tub, if the hinge is rotated to separate the feed roll from the glue tub, the upper opening of the glue tub is exposed. Thus, a glue supply opening through which glue can be easily supplied is provided. Further, if the feed roll is removed together with the hinge, the glue supply opening is further enlarged, so that the glue can be supplied more smoothly and the apparatus can be easily cleaned.

In an automatic wallpaper sizing machine, the cloth is usually unwound from a web roll rotatably supported at the rear of the sizing machine main body, and a tension bar bridged by legs supporting the main body. Is transported through the But,
As shown in FIG. 5A, when the web roll R is supported at a position away from the main body behind the tension bar 42, the web roll R dances with the feeding of the cross C,
Rattling may occur during operation. In this case, there is a danger that the unfolded and conveyed cloth C also becomes blurred, causing meandering and wrinkles, and cutting and gluing of the cloth may be defective.

Further, when the apparatus is stopped, the pull-out force of the cloth C also stops, but the rotation of the material roll R does not stop immediately due to inertia. Therefore, as shown in FIG. C is bent.
This deflection may increase due to the weight of the cloth even when the apparatus is stopped. As described above, when the operation is restarted in a state where the cloth is bent, no tension is applied to the cloth which is initially conveyed, and meandering and wrinkling of the cloth may occur before the cloth disappears. .

Therefore, in the present invention, by setting the support shaft of the raw roll at a position substantially vertically below the tension bar, the feeding direction of the cloth from the raw roll can be adjusted. Because the roll can be set almost vertically, the weight of the material roll works only in the direction of gravity, preventing wobble and wrinkles from rattling and blurring. Feeding out and gluing of the cloth can be performed.

Further, in the wallpaper cutting device according to a fourth aspect of the present invention, the guide plate that covers the upper portion of the wallpaper over the entire width direction is slid while the transported cloth is in contact with the entire width direction in a tension state. Since the entire cloth slides on this guide plate to function as a moving stay part, the cloth is cut between a pair of upper and lower rotating blades and passes through the inside of the cutting device before gluing. Compared with the conventional cutting device sent to the machine body, wrinkles are less likely to be generated in the cloth, and stable transport is performed.

As described above, the cutting device is installed on the path of the cloth from below the wallpaper cutting device to the guide plate so that the rotation direction is along the vertical direction. The edge of the cloth is smoothly and vertically cut while being conveyed because the blade hits the rotary blade at a position where the blade is pressed. As described above, in the present cutting apparatus, it is not necessary to perform cutting while transporting between a pair of upper and lower rotating blades as in the related art, and the cutting of the cloth proceeds easily only by contact with one rotating blade.

Accordingly, not only can the apparatus configuration be simplified than in the conventional apparatus using a pair of upper and lower rotary blades, but since only one rotary blade is to be replaced, maintenance work can be reduced.

Further, as described in claim 5, the rotary blade is built in a rotary blade built-in cartridge together with a shaft that supports the rotary blade, and the cartridge is detachably mounted on the wallpaper cutting device in units of the cartridge, thereby replacing the rotary blade. In this case, since the entire cartridge can be removed, there is no danger of injuries caused by directly waving the blade portion as compared with a case where only the rotary blade is removed from the shaft, and safety is improved.

In the arrangement of the rotary blade of the present wallpaper cutting device, the blade portion is exposed to the outside, and there is a danger that an operator touches from the outside and there is a risk of injury. By providing a protective wall member for covering the exposed blade portion, the danger can be avoided and the safety is further improved.

If the protective wall member has a function of guiding the ears separated from the cloth toward the inside of the apparatus, the ears can be satisfactorily applied to the cloth body conveyed above the apparatus (on the guide plate). Separation and falling into the gluing machine main body side are avoided.

When the cartridge with a built-in rotary blade is mounted on the wallpaper cutting device, a shaft, which is a rotary shaft for supporting the rotary blade, transmits the rotary motion from the drive mechanism of the sizing machine main body. It is assumed that the driving mechanism is connected to a rotating shaft of a rotating blade driving means which is separate from the driving mechanism. This wallpaper cutting device is attached to an arbitrary position corresponding to the desired cutting position across the width of the cutting device so that the cloth can be cut at a desired position. Further, it is preferable that the position of the cartridge can be adjusted even after the mounting.

For example, the upper surface of the under stay constituting the main body frame at the bottom of the cutting device is used as a rail mechanism, and the cartridge is slidably mounted on the rail mechanism, and the position is adjusted by moving on the under stay. Thereafter, the configuration for fixing the position is simple.

[0037]

BEST MODE FOR CARRYING OUT THE INVENTION As one embodiment of the present invention, an automatic wallpaper equipped with a slitter (cutting device) to which a rotary blade built-in cartridge having a single (single blade) and a shaft built therein is detachably mounted. Fig. 1 to Fig. 4
Shown in FIGS. 1A and 1B are side perspective views showing a schematic configuration of a slitter and a gluing machine main body. FIG. 1A shows a cross sandwiching state in which upper and lower structures are closed, and FIG. 1B shows a state in which an upper structure is opened. Here, the illustration of the legs supporting the gluing machine main body is omitted.

FIG. 2A shows a glue supply state in which the delivery roll is separated from the glue tub by rotating the hinge.
(B) is a side see-through view explaining the state which removed the hinge together. FIG. 3 is a schematic perspective view of the slitter showing a cross-cut state with a side plate removed. FIG. 4 is a schematic side view illustrating the overall configuration of the automatic wallpaper sizing machine according to the present embodiment.

The automatic wallpaper sizing machine according to the present embodiment is shown in FIG.
As shown in FIG. 1, the gluing machine main body 1 is mounted on a pedestal 30 supported by legs 31. As shown in FIG. 1, the gluing machine main body 1 mainly includes a lower structure 2 in which a glue tub 4 for storing the glue is installed, and an upper structure 3 installed to be openable and closable with respect to the lower structure 2. Be composed.

In the lower structure 2, a delivery roll 6 constituting a pinch roll for taking in the cloth C from the rear side into the gluing machine main body 1, and a glue for transferring and applying the glue in the glue tub 4 to the back of the cloth. A roll 8, a doctor roll 7 that is in contact with the gluing roll 8 and adjusts the amount of glue, and a leveling roll 9 that applies an appropriate tension to the cloth C and feeds the cloth C in the front direction can be interlocked with each other via gears. It is axially supported by a side plate of the glue tub 4 or a bearing plate parallel thereto so as to be arranged in parallel at a predetermined interval.

On the other hand, in the upper structure 3, an upper pinch roll 10 which constitutes a pinch roll and has a measuring function in combination with the delivery roll 6, and a roll and a gear arranged in the lower structure 2. A drive roll 13 for applying a feeding tension toward the front of the gluing machine main body to the cloth C, and a holding stay for pressing the cloth C from above between the upper pinch roll 10 and the drive roll 12. 11 are supported by bearing frames on both sides of the main body of the upper structure 3 so as to be arranged in parallel at a predetermined interval.

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

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

In this embodiment, the slitter 20 mounted on the rear part of the gluing machine main body 1 cuts the cloth with only one rotary blade 23. The rotary blade 23 has a shaft that supports the same. In addition, the rotary blade 23 is built in the rotary blade built-in cartridge 22. When the rotary blade 23 is replaced, it is sufficient to remove the cartridge 22 together.
The risk of injury such as touching the blade portion is reduced as compared with the case where 3 is removed.

The cartridge 22 further includes a slitter 2
No. 0 is detachably attached to the under stay 26 at the bottom of the main body. The understay 26 has a rail mechanism at the upper portion, and slides on the understay 26 so that the position of the cartridge 22 can be adjusted in the width direction of the apparatus. Accordingly, the sliding movement of the cartridge 22 causes the rotary blade 2 to move to a desired cross cutting position.
3 can be adjusted so that the cartridge 22 can be releasably fixed on the under stay 26 with a boss member or the like after the positioning.

Further, a protective wall member 24 for covering the blade portion on the side exposed to the outside is provided integrally with the cartridge 22 as an extension of the housing of the cartridge 22. The edge guide portion 25 of the slitter side plate is more curved than the rotary blade of the protective wall member 24 toward the inside of the slitter 20, and the ear portion P separated from the cross C is used as the slitter 20. And fall down the device.

Further, in the present slitter 20, an extension 27 extending vertically downward is provided on the front surface of the under stay 26 in the width direction of the apparatus, and a leg for supporting the gluing machine main body 1 from below. The cross C conveyed via the tension bar 32 bridged along the apparatus width direction to the extension 31 is pressed from the front side by the pressing stay 28 which is supported at a position facing the extension 27. Extension 27
Is configured to slide upward on the surface of.

On the other hand, above the slitter 20, there is provided a guide plate 21 for covering the upper part over the entire width direction of the apparatus. Functions as a stay that slides while contacting. Accordingly, the guide plate 21 is slid upward from below the slitter 20 while being pressed by the holding stay 28 on the surface of the extension 27 via the tension bar 32.
The cross C that moves upwards further slides on the upper surface of the guide plate 21 and passes therethrough. As described above, the cloth C passing over the slitter 20 is conveyed from the surface of the extension 27 onto the guide plate 21 while being given an appropriate tension.

The extension 2 below the slitter 20
On the path of the cross C from the surface 7 to the guide plate 21, a rotary blade 23 built in the cartridge 22 is installed so that the rotation direction thereof is along the vertical direction, and the rotary blade 23 is conveyed with an appropriate tension. The coming cloth C hits the blade portion of the rotary blade 23 at a position where the blade edge is pressed against the back side.
Therefore, the side edge of the cloth C is conveyed while the rotary blade 23
It is cut smoothly and vertically just by hitting the blade.

As described above, the cross C whose entire rear surface slides on the guide plate 21 and is conveyed is hardly wrinkled.
As the conveyance proceeds in a stable state, the side edges are cut smoothly and vertically only by hitting the rotary blade 23.

As described above, the slitter 20 of the present embodiment
In this case, it is not necessary to perform cutting while transporting between a pair of upper and lower rotating blades as in a conventional slitter. in this way,
Since the load for rotating one rotary blade 23 is greatly reduced as compared with the load for rotating a pair of rotary blades in the related art, a small driving source having a smaller power than the conventional one is sufficient. is there. Therefore, since the drive mechanism mounted on the main body is small, the size and weight of the device can be kept small, and it is configured to be smaller and lighter than the conventional automatic sizing machine. Handling is simplified.

In this embodiment, the rotary blade 23
Is rotated when the slitter 20 is mounted on the gluing machine body 1 with the rotary blade built-in cartridge 22 attached.
The shaft No. 3 is connected to a gear system on the side of the sizing machine main body, and is rotated in conjunction with the operation of the sizing machine main body 1 by transmitting the rotational motion.

In the gluing machine main body 1 having the above-described configuration, as shown in FIG. 1B, the upper structure 3 is rotated with respect to the lower structure 2 so as to be opened, and the guide plate 21 of the slitter 20 is opened. When the upper structure 3 is closed on the upper and lower structures 2 with the cloth C unwound from the raw fabric roll R placed with its tip hanging down in front of the main body, the upper structure 3 is closed as shown in FIG. Cross C between predetermined rolls of lower structure 2 and upper structure 3
Is sandwiched.

When the electric motor is driven in this state of holding the cloth, the rotation of the delivery roll 6 is started, and at the same time, the other rolls connected to the delivery roll 6 via a gear and the rotary blade of the slitter 20 are rotated. 23 also starts interlocking rotation via the shaft.

As a result, the cross C is brought into contact with the rotary blade 23 while being conveyed with appropriate tension from the surface of the extension portion 27 below the slitter 20 to the guide plate 21 via the tension bar 32, and the side edge thereof is caused. The part is cut at a predetermined position. The separated ear part P is the guide part 25.
The cloth C is cut toward the inside of the slitter 20 and falls downward, while being cut down and adjusted to a desired width.
The main body is conveyed while sliding along the upper surface of the guide plate 21 over the entire width of the rear surface thereof, drawn into the inside from the rear of the sizing machine main body 1, and while being conveyed forward, scoops up the glue in the glue tub 4 on the way. When the amount of glue is adjusted by the doctor roll 7 and reaches the rotating glue roll 8, the glue is transferred from the glue roll 8 to the back surface and is sent out from the front with the glue applied.

In the automatic wallpaper sizing machine according to the present embodiment, as shown in FIG. 4, the support shaft 33 of the material roll R is positioned almost vertically below the tension bar 32 bridged by the leg 31. It was configured to be installed. This allows the cloth C to be unwound from the material roll R in a substantially vertical direction, so that the weight of the material roll R acts only in the direction of gravity and suppresses rattling and blurring that may cause meandering and wrinkles. In addition, since the bending of the cloth C at the time of stoppage of operation is less likely to occur, stable feeding and gluing of the cloth C can be performed.

In the present embodiment, the delivery roll 6 of the lower structure 2 is configured to open and close with respect to the upper opening of the glue tub 4 by rotating the hinge 5. Therefore, as shown in FIG. 2 (a), when the delivery roll 6 is rotated together with the hinge 5 in a direction away from the glue tub 4 to be in an open state, the upper opening of the glue tub 4 is exposed, and this exposed area is defined. The glue supply opening 13 can be used. Therefore, when supplying the glue to the glue tub 4 such as refilling the glue, the upper structure 3 is opened, and the delivery roll 6 is rotated by the hinge 5 so that the glue tub 4 is rotated.
, The glue can be smoothly supplied into the glue tub 4 from the glue supply opening 13 formed therein.

Further, the hinge 5 is detachable from the glue tub 4, and as shown in FIG.
At the same time, the hinge 6 can be removed from the lower structure 2 together with the hinge 6, so that cleaning after the operation is very easy.

In the above embodiment, the slitter 2 is mounted in the state where the rotary blade built-in cartridge 22 is mounted.
0 is attached to the sizing machine body 1, the cartridge 2
The rotary blade 23 is rotated via the shaft by connecting the shaft built in 2 to a gear system for transmitting the rotational motion of the driving source of the gluing machine main body 1, but only one rotary blade is used. Since only a small driving power is required to rotate the slitter 20, a configuration in which a dedicated small motor is mounted on the slitter 20 separately from the gluing machine main body side is also possible. In this case, the burden on the drive source on the gluing machine main body side is further reduced.

[0060]

As described above, claim 1 of the present invention is provided.
The automatic wallpaper sizing machine described in (1) is smaller and lighter than the conventional automatic sizing machine compared to the conventional manual sizing machine. Has the effect of simplifying the handling.

Further, in the automatic wallpaper sizing machine of the present invention, the support shaft of the material roll is installed at a position substantially vertically below the tension bar bridged below the legs supporting the sizing machine main body. This prevents rattling and wobbling, which can cause meandering and wrinkles when sending the cloth from the material roll, and also makes it difficult for the cloth to bend when the operation is stopped. Can be performed.
