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 sizing to the back surface of a sheet-like wall covering applied to an indoor wall surface or the like. And a piping system for continuously supplying the same.

[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. 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 pedestal supported by legs. The sheet-like wall covering material (hereinafter, referred to as cloth) sandwiched between the upper and lower structures is transferred by a roll while transferring the glue from the glue tub to the back of the cloth wall covering material by a gluing roll.

[0003] More specifically, a cloth fed from a raw roll is placed on a lower structure with its leading end hanging down from the front of the main body, the upper structure is closed, and a cloth is inserted between predetermined rolls of the lower structure and the upper structure. In the sandwiched state, the hand-operated device pulls forward with the tip of the cloth to rotate a part of the roll sandwiching the cloth up and down, and rotates the other rolls interlockingly via gears to glue the cloth. The machine is transported from the rear surface to the front side of the machine body. During this conveyance, the glue is transferred from the roll to the back surface of the cloth on the vertex of the roll that is pulling up the glue in the glue tub by its rotation, and the cloth is sent out from the front surface in a state where the glue has been applied. In an automatic device, by connecting the shaft of a predetermined roll to a drive source such as an electric motor and rotating it,
Other rolls also rotate interlockingly via gears.

Glue is applied to the back surface of the cloth by directly transferring the glue with a roll for pulling the glue from the glue tub, and a glue roll for raising the glue and a gluing roll for applying the glue are separately provided. There is a case where the paste is transferred from the paste-up roll to the paste roll. In recent years, the use of an automatic wallpaper gluing machine has been preferred in that efficient and uniform gluing can be performed.

[0005]

However, since the sizing machine is transported to the site and assembled there, after use, it is disassembled and brought back and stored, it is desirable that the sizing machine be small and lightweight. However, since the automatic wallpaper sizing machine includes a driving unit such as a motor and a control unit thereof, the size and the weight of the automatic wallpaper sizing machine are increased compared to the manual type.

Therefore, in such an automatic wallpaper sizing machine,
The necessity of reducing the size and weight has arisen due to the configuration of the gluing machine body. It is the glue tub that mainly determines the size of the gluing machine body. However, simply reducing the size of the glue tub requires frequent supply of glue, and the work is interrupted each time, so that efficient gluing work cannot be performed.

Therefore, a configuration has been considered in which glue is continuously and automatically supplied from a glue tank outside the apparatus into a glue tub by using a pump mechanism. For example, a glue inlet is formed at the center of the bottom of the glue tub, and the tip of a glue supply pipe hose extending from the pump mechanism is fitted and attached to the inlet, and the glue in the tank is fed into the glue tub by the pump mechanism. There was something to supply.

However, in such a conventional glue supply means, when the glue supply piping hose is detached from the glue tub after the end of the work, if glue remains in the glue tub, the glue falls from the inlet at the bottom and the glue falls. Not only is it difficult to handle because it becomes dirty, but in order to attach the glue supply pipe from the glue supply pump to the glue tub inlet for glue supply, it must be done from the lower back side of the device, Do the alignment by groping or
In addition, it was a troublesome and complicated process, such as sneaking under the gluing machine.

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a wallpaper sizing machine for refilling glue from the outside into a glue tub. The purpose is to provide a sizing machine.

[0010]

In order to achieve the above object, a wallpaper sizing machine according to the first aspect of the present invention feeds a sheet-like wall covering material pulled in from a rear surface of a sizing machine body to a front side. Meanwhile, in a wallpaper gluing machine that continuously applies glue by pulling up the glue stored in the glue tub in the gluing machine body with a roll and transferring the glue to the back surface of the wall covering material, A glue introduction path for refilling the glue is provided, and the introduction path has an inlet for receiving the supply of the glue at the side wall position of the glue tub and an outlet opening into the glue tub at a middle position in the width direction of the glue tub. And extend in the width direction along the inner wall surface on the front side and / or the rear side of the glue tub.

According to a second aspect of the present invention, there is provided a wallpaper sizing machine according to the first aspect, wherein the glue introduction path is formed at a substantially central portion in a width direction of the glue tub. It has one outlet.

According to a third aspect of the present invention, there is provided a wallpaper sizing machine according to the first aspect, wherein the plurality of glue introduction paths are distributed in the width direction of the glue tub. It has an outlet.

Further, in the wallpaper gluing machine according to the invention of claim 4, in the wallpaper gluing machine according to claim 1, the glue introduction path is provided on a front side and / or a rear side of the glue tub. It is formed by a space between an inner wall surface and a cover plate that is detachably disposed at an interval inside the inner wall surface.

Furthermore, the wallpaper gluing machine according to the invention of claim 5 is the wallpaper gluing machine according to claim 1, wherein
The glue introduction path is formed by a tube attached to an inner wall surface on a front side and / or a rear side of the glue tub.

According to a sixth aspect of the present invention, there is provided the wallpaper sizing machine according to the first aspect, wherein an inlet of the glue introduction path communicates with a sizing supply pipe from a sizing supply pump. Is what it is.

According to a seventh aspect of the present invention, there is provided a wallpaper gluing machine according to the sixth aspect, wherein the inlet of the glue introduction passage and the glue supply pipe are separated by a pipe joint. What is connected.

Further, in the wallpaper sizing machine according to the invention of claim 8, in the wallpaper sizing machine according to claim 6, the glue introduction path and the glue supply pipe are constituted by an integral pipe. Things.

According to a ninth aspect of the present invention, there is provided a wallpaper gluing machine according to the sixth, seventh or eighth aspect of the present invention, wherein the glue is supplied by sucking the glue from a supply glue container. It is characterized in that the pump is mounted on the gluing machine body.

A wallpaper gluing machine according to a tenth aspect of the present invention is the wallpaper gluing machine according to the first aspect, wherein a glue replenishing funnel is detachably mounted at an entrance of the glue introduction path. It is.

In the present invention, as a glue introduction path for supplying glue from the outside into the glue tub, an inner wall surface on the front side or the rear side of the glue tub from an inlet for receiving the glue at the side wall position of the glue tub. In the glue introduction path, the inlet is easily positioned by setting the glue tub side wall position as the inlet, since the outlet extends into the glue tub in the widthwise middle of the tub along the width direction. The glue can be visually confirmed, and the glue supply operation becomes much simpler than the conventional glue introduction from the bottom side of the glue tub.

Also, the entrance provided at the side wall position of the glue tub can be set at an appropriate height from the bottom of the glue tub, so that even if this entrance is in an open state, the glue in the glue tub spills out from the entrance. You can keep out. Therefore, for example, when the glue supply pipe from the glue supply pump is attached to the inlet to supply the glue to the introduction path, even if the pipe is removed, the inside of the glue tub is formed as in the case where the inlet is formed on the bottom of the conventional glue tub. The glue remaining on the surface does not spill out, and the handling at the time of clearing after the gluing operation is easy.

Further, when such a glue introduction path is provided so as to be detachable from the glue tub, it is an installation position where the work can be performed from the upper opening side of the glue tub exposed when the upper structure is opened. Therefore, the attachment and detachment work can be performed very easily as compared with the conventional work on the lower back side of the glue tub.

In the present invention, the outlet of the glue introduction path is
A configuration in which the paste to be discharged can spread evenly in the paste tub is desired. For example, a single outlet may be provided substantially at the center in the width direction of the glue tub, and the glue may be spread uniformly around the outlet in the entire circumferential direction. Alternatively, a configuration may be adopted in which a plurality of outlets are distributed and arranged in the width direction of the glue tub so that glue is discharged from each of these outlets as a whole.

The glue introduction path of the present invention usually needs to be installed in a region which does not affect the rotation of a gluing roll or a doctor roll which is supported on both side plates of the glue tub. In consideration of the above, it is most convenient and desirable to arrange along the inner wall surface on the front side or the rear side of the glue tub.

As a specific configuration of the glue introduction path, various tubular members such as pipes and hoses can be used, but a configuration that can easily clean the glue introduction path is desirable. For example,
According to a fourth aspect of the present invention, when a cover plate that covers the inner wall surface of the glue tub and forms a tubular glue introduction path is detachably disposed, the inner wall surface of the glue tub covered with the cover plate is formed of glue. When the cover plate is removed from the glue tub, the inside of the introduction path is exposed, so that cleaning can be performed very easily.

The cover plate that forms a tubular glue introduction path by partially covering the inner wall surface of the glue tub may be fixed by any fixing method that can be easily removed from the glue tub, such as screwing. At the time of installation, a sealing member that can be in close contact with the area of the cover plate member that is in contact with the inner wall of the glue tub so that the inside of the flow path is sealed except for the outlet so that the glue can smoothly proceed in the introduction path. May be provided. Also, the contact part of both members is
It is also possible to have irregular shapes that fit each other.

Further, the present invention is not limited to the configuration in which the glue introduction path is formed by arranging the detachable members as described above. It may be configured to be used. In this case, it is possible to simplify the entire operation process without the trouble of attaching and detaching members. Of course, this tube may be detachable from the inner wall surface of the glue tub, and the tube itself may have a two-part assembly / disassembly structure. That is,
When the two members are combined, a tubular glue introduction path is formed, and if the inner wall of the tubular glue introduction path is exposed at the time of disassembly, the inside of the tube can be more easily and easily cleaned.

Generally, the glue is actually supplied from the outside to the glue tub by using a glue supply pump. In this case, the glue supply pipe from the glue supply pump is connected to the glue introduction path. You only have to communicate with the entrance. Since this pipe communication work is performed on the side wall of the glue tub, the work can be completed easily and in a short time.

In order to connect the glue supply pipe to the glue introduction path, the pipe may be directly connected to the inlet, but it is troublesome to provide a connection mechanism at the pipe or the inlet. The connection can be separated via a pipe joint, eliminating the need to provide a special connection structure at the pipe or inlet, and the connection can be easily disconnected by removing the joint when removing. Also, the joint side can be easily cleaned.

Further, as described above, instead of using a dedicated member for forming the glue introduction passage, the glue is supplied by a pipe integral with the glue supply pipe from the glue supply pump. An introduction path may be configured. That is, the extension of the glue supply pipe from the pump is attached to the glue tub to constitute the glue introduction path, and the glue can be easily attached to and detached from the glue tub and washed. In this case, the entrance of the glue tub side wall may be a through hole into which the pipe extension can be inserted.

When the extension of the glue supply pipe from the glue supply pump is used as the glue introduction path, it is easy to clean the inside of the glue tub after removing the pipe, and to clean the inside of the pipe by the pump side. Can be performed at the same time as the water circulation cleaning. Also,
Even if some glue remains inside the pipe, it will not hinder the next use if the inside of the pipe is sealed to prevent drying.

As described above, if the glue supply pump is used,
The glue can be continuously sucked from the glue container for replenishment and automatically supplied into the glue tub, so that further gluing work can be automated and the working efficiency can be further improved.

As such a glue supply pump, an existing pump separate from the wallpaper gluing machine may be used, but it may be configured to be provided in the gluing machine body. If the pump is built in the gluing machine in this way, when continuous automatic supply of the glue is desired, there is no need for a separate pump and the number of components to be prepared is also reduced accordingly. The transportation to the site is simplified, and forgetting to transport the pump does not become a problem, and the continuous automatic supply of the glue by the pump is always possible at any site.

Of course, in the wallpaper sizing machine according to the present invention,
The method is not limited to the method of supplying the paste into the paste introduction path using such a paste supply pump. Even in the case where a pump cannot be equipped or a pump cannot be prepared, in the present invention, since the inlet of the glue introduction path is provided on the side wall of the glue tub, for example, if a glue replenishing funnel is attached to the inlet, the glue is directly poured from the bucket. It is also possible.

In the wallpaper sizing machine according to the present embodiment, the roll configuration in the sizing machine main body 1 is basically the same as that of the conventional automatic wallpaper sizing machine. The cloth C unwound from the material roll R supported by the cross support rods 22 provided on both sides of the back surface of the gluing machine main body 1 on the legs 21 of the pedestal 20 on which the main body 1 is mounted is attached to the gluing machine main body. 1, a lower feed roll 5 constituting a pinch roll for taking in from the rear surface, a glue roll 7 for transferring and applying the glue in the glue tub 4 to the back of the cloth, and adjusting the glue amount by contacting the glue roll 7. Doctor roll 6 and leveling roll 8 for sending the glue applied to the back side of cloth C to the front side while leveling
Are arranged in parallel so as to be interlocked with each other via a gear and at a predetermined interval.

On the upper structure 3 side which is attached to the lower structure 2 so as to be openable and closable, the lower delivery roll 5
Upper pinch roll 9 which constitutes a pinch roll opposite to
And a drive roll 11 for applying a feed tension toward the front of the sizing machine body 1 to the cloth C by interlocking with a roll arranged in the lower structure 2 via a gear, and these upper pinch rolls 9. A press stay or a press roll 10 for pressing the cloth C from above between the drive roll 11 and the drive roll 11 are arranged in parallel at a predetermined interval from each other.

In the present gluing machine, the glue container 12 for containing the glue
And a pump device 13 that sucks the glue from the glue container 12 and discharges the glue into the glue tub 4 is installed outside the gluing machine, and a glue supply piping hose 14 extending from the pump device 13 is connected to the glue tub side wall 4A.
Directly or through a separable joint. The connection of the piping hose 14 to the inlet 15 can be performed easily and in a short time because the connection position can be visually confirmed.

In the glue tub 4, a cover plate member 16 that covers a part of the inner wall surface of the glue tub front surface 4 B and forms a tubular space therein,
From the inlet 15 to the middle position in the width direction of the glue tub, it is detachably attached along the front surface 4B of the glue tub by screwing, and this tubular space forms the glue introduction passage 17. In the present embodiment,
The cover plate member 16 is in contact with the glue tub side wall 4A such that the opening edge on one end side covers the entrance 15 and, when the other end side is open, enters the same as the one end side and faces the 15 The tubular space may be closed by contacting the glue tub side wall 4C, or a closed side surface for closing the tubular space may be provided on the other end side.

The cover plate member 16 is provided with a glue discharge port 18 which opens toward the inside of the glue tub at the middle position in the glue tub width when the glue tub is mounted. Therefore, the glue sent out into the tubular glue introduction passage 17 formed by the cover plate member 16 and a part of the inner wall surface of the glue tub front surface 4B covered by the member 1616 is supplied into the glue introduction passage 17. To discharge port 18
The ink is discharged while being spread almost evenly in the circumferential direction in the glue tub 4.

In the automatic wallpaper sizing machine of the present embodiment having the above-described glue introduction path 17, during the operation of the sizing machine, the glue in the glue container 12 is continuously fed by the pump device 13 which is driven simultaneously. From the glue supply pipe hose 14 to the inlet 15 of the glue tub side wall, the glue introduction path 17 inside the cover plate member 16, and the discharge port 18
Through the glue tub 4 continuously.

Normally, in such a continuous supply of the glue by the pump device 13, for example, the glue roll 7 is prevented from overflowing from the glue tub 4 to prevent the good glue application by the glue roll 7. A predetermined upper limit height position of the size liquid surface within 4 is set, and when the size liquid surface reaches the position, control such as temporarily stopping the driving of the pump device is performed.

Therefore, at the end of the operation of the gluing machine, it is conceivable that glue may remain in the glue tub 4 up to this upper limit height position.
By setting the through hole constituting the inlet 15 of the pipe above the upper limit height position, the piping hose 14 is connected to the glue tub 4.
The glue does not spill out of the glue tub 4 when it is removed from the glue tub 4.

In this embodiment, the work of attaching and detaching the cover plate member 16 to and from the glue tub 4 can be carried out from the upper opening side of the glue tub 4 exposed when the upper structure 3 is opened. In contrast to the prior art, the operation of attaching and detaching the glue tub 4 on the lower back side is much easier and simpler. Further, the cover plate member 16 removed from the glue tub 4 after the gluing operation is completed, Since the inside that was a part of the introduction path 17 is exposed, cleaning can be easily performed.

When the cover plate member 16 is attached to the inner wall surface of the glue tub 4 to form a tubular space as in this embodiment, the supplied glue is forcibly fed by a pump mechanism. . In order to discharge the commonly used glue satisfactorily and continuously, about 2 kg / c inside the glue introduction path
to come takes m ² things pressure, if there is a gap between the cover plate member 16 and Norioke inner wall, adhesive leaks from the gap. Further, in the contact state with a gap, rattling occurs between members during operation of the apparatus, which may adversely affect a smooth gluing operation.

Therefore, the inner wall surface of the glue tub which comes into contact with the cover plate member 16, ie, in this embodiment, between the glue tub front surface 4B and the glue tub side wall 4A on the entrance 15 side, the two are tightly tightly fitted without any gap. It is desirable to provide combining means.

FIGS. 3 to 6 show one example of such fitting means. This has a protrusion at the upper or lower part of the glue tub front surface 4B for locking the upper end or the lower end with which the cover plate member 16 comes into contact at a predetermined installation position with respect to the glue tub front surface 4B. A groove having a concave cross section that forms a tubular space by opposing the two members is provided in a region where the two members oppose each other on the other side of the locking portion in the lower portion over the glue tub width direction. The two members are fixed by inserting a clip having a cross-sectional shape that matches the tubular space.

In the present embodiment, as shown in the side sectional view of FIG. 3, a projection 4D is formed on the bottom side of the glue tub front surface 4B on the lower side, and a projection 4D is formed on the lower end edge of the cover plate member 16 on the lower side. The locking portions 16A for locking are provided in the extending direction of the cover plate member 16, respectively. Further on the upper side, the cover plate member 16
A groove 16B having a concave cross-section is provided on the upper surface of the cover, and the locking portion 16A is locked to the protrusion 4D above the glue tub front surface 4B so that the cover plate member 16 is brought into contact with the glue tub front surface 4B. Concave member 4 that forms a substantially tubular space facing groove 16B
X is projected in the width direction of the glue tub, and the clip 30 whose cross-sectional shape fits into the substantially cylindrical space thus formed is slid and inserted, whereby the cover plate member 16 is moved forward by the glue tub front surface 4B. Fixed securely.

On the other hand, as means for fitting the cover plate member 16 and the glue side wall 4A on the inlet 15 side, as shown in FIG. A fitting groove 4Y to be fitted is formed, and as shown in FIG.
By pressing the cover plate member 16 from the other end by a leaf spring 31 provided on the glue tub side wall 4C facing the glue tub 4 and pressing and fixing the cover plate member 16 to the glue tub side wall 4A, One end of the cover plate member 16 is tightly fixed in a fitted state. In this case, by setting the other end of the cover plate member 16 to be closed by the closed side surface, the leaf spring 31 can contact and press the closed side surface of the other end side, and at the other end side of the cover plate member 16. There is no need to consider the problem of adhesion to the glue tub side wall 4C, and the configuration becomes easy.

Further, as the pressing and fixing mechanism on the other end side, not only the structure using the leaf spring 31 but also a fixing method utilizing the rotation of the fixing plate 32 as shown in FIG. 6 is effective. That is, the fixing plate 32 is rotatably mounted on the outer surface on the other end side of the cover plate member 16, and the cover plate member 16 is fitted to the front surface 4B of the glue tub by fitting the opening edge of one end side into the fitting groove 4Y. By rotating the fixing plate 32 in the contact state and pressing the tip of the fixing plate 32 against the glue tub side wall 4C, the other end of the cover plate member 16 is urged toward one end, and the cover plate member 16 is pressed and fixed. Is what is done. The mechanism using the fixing plate 32 is more preferable than a leaf spring in terms of deterioration of members and a problem of cleaning when glue adheres.

In the fitting means as described above, the cover plate member 16 can be easily and firmly fixed to the inner surface of the glue tub without any gap by the lower locking state and the sliding insertion of the upper clip 30. The clip 30 can be easily removed by pulling out the slide. In addition, when the cover plate member 16 is securely fixed in this way, rattling of the member is suppressed even during continuous supply of glue, and a smooth gluing operation can be maintained. Further, the groove 16B for forming the substantially tubular space into which the clip 30 is inserted and the concave member 4X opposed to the groove 16B are not limited to the configuration provided in the upper part of the cover plate member 16, but may be provided in the lower part. Good. However, the operation is simpler if provided in the upper part.

In the above embodiment, the glue introduction path 17 is constituted by the tubular space formed by the cover plate member 16 covering a part of the inner wall surface of the glue tub front surface 4B. However, the present invention is not limited to this. A configuration in which a glue introduction path is formed along the inner wall surface behind the glue tub may be adopted. Further, a configuration may be adopted in which the bottom surface on the front side or the rear side of the glue tub is covered to form a glue introduction path.
In this case, a part of the bottom surface of the glue tub may be covered with a cover plate member having a substantially semicircular cross section or a substantially cono-shaped cross section.

As shown in FIG. 7, in addition to the above-mentioned member which is attached to the glue tub to form a glue introduction path, as shown in FIG. It can also be used as a glue introduction path in the tub 4.

Also in this case, a fixing means for detachably fixing the extension 14x in the glue tub 4 is provided. In the gluing machine shown in FIG. 7, a locking portion 19 for locking the extension 14x is provided on the inner surface of the glue tub. In the extension 14x, the hose tip is closed and the discharge port 18 is formed on the side of the hose facing the inside of the glue tub at the middle position in the width direction of the glue tub. The end opening may be used as a discharge port by bending the glue tub rearward. Alternatively, a configuration may be adopted in which a separate discharge member that guides the glue from the hose opening end toward the back of the glue tub is detachably attached to the hose tip.

When the extension 14x of the glue supply pipe hose 14 extending from the pump device 13 is used as a glue introduction path into the glue tub, the extension 14x
When washing after removing the glue from the glue tub 4, the extension 1
4x is subjected to water circulation cleaning at the same time as the pump device as a member on the pump device 13 side, so that there is no trouble in cleaning on the sizing machine side. Also, if some glue remains inside the piping hose 14, if it is stored in a sealed state so that the inside does not dry, there is no problem even if it is used again next time, so the clearing work after the gluing work will be Easy.

Further, instead of the extension of the glue supply pipe hose 14, a separate pipe may be attached as the glue introduction path along the inner wall surface on the front surface or the rear surface of the glue tub. In this case, if the pipe is made detachable and detached after the work is completed, water can be washed through the inside of the pipe, but the pipe can be assembled and disassembled for easier and complete cleaning. It is desirable to be made of a member and to be able to expose the inside during disassembly. In addition, as a material of the tube, it is preferable to use a resin that does not easily adhere to the resin, or to apply a resin coating to a material molded from a member such as a metal.

FIG. 8 shows an example of such a two-member tube.
Shown in In this tube body 40, a lower tube member 41 having a substantially cono-shaped cross section and an upper tube member 42 having a substantially cono-shaped cross section that is wider than the lower tube member 41 overlap each other in a state of being held together and have a substantially Rono-shaped cross section. This forms a tubular glue introduction passage 45 in a shape of a circle.

The tube 40 has a groove which fits together as a lock mechanism for maintaining the assembled state without separating the two tube members (41.42) by the pressure of the glue flowing inside the glue introduction passage 45. 43 and the ridge 44 are provided along the longitudinal direction of the tube 40. Therefore, if the lower tube member 41 and the upper tube member 42 are slid and overlapped while the grooves 43 and the ridges 44 are fitted to each other, the tube 4
The upper and lower pipe members (41, 42) are not separated and disassembled as long as the assembly can be assembled and the movement in the sliding direction is restricted.

For example, when a pipe 40 separate from the glue supply pipe 14 is installed in the glue tub 4, the one end opening of the pipe 40 and the inlet 15 of the glue tub side wall 4A need to communicate with each other. However, the opening at one end of the tube 40 in the installed state does not always coincide with the position of the inlet 15, such as when the inlet 15 is provided at a position higher than the opening at the one end of the tube 40. Are interposed between the communication members.

Therefore, if one end of the tube 40 is fixed by attaching the communication member, the sliding movement at one end of the tube 40 is easily restricted. At this time, it is easy to regulate the sliding movement of the upper and lower pipe members (42, 41) at the other end side of the tube 40 only by protruding the stopper at which the other end of the tube 40 abuts on the glue bottom 4E. Can be done.

FIG. 9 shows an example of a configuration in which the pipe 40 and the inlet 15 are communicated by a communication member as described above. FIG.
(A) is a front view in which the glue tub entrance side is seen through the glue tub front surface 4B, (b) is a side view in which the glue tub side surface 4A is seen through, and (c) is a plan view in which it is seen from above.

FIG. 9 shows an elastic rubber member 5 as a communicating member.
The case where 0 is used is shown. The elastic rubber member 50 covers the inner surface area of the glue sidewall 4A including the inlet 15 and the partial area of the glue front surface 4B and one end of the tubular body 40 with a predetermined space inside, so that the tubular body is moved from the inlet 15 to the tubular body. A sealed glue channel 53 is formed over one end of the opening 40.

That is, the inlet side 51 is fixed to the inner surface of the side wall 4A of the elastic rubber member 50 by abutting screws.
A tunnel-shaped recess having an upper inner periphery coinciding with 5 is provided, and as shown in the direction of the thick solid line arrow in FIG. A flow path is formed to direct the glue introduced from the inlet 15 downward with the portion, and a pipe mounting portion 52 extending in an L-shape in front view from below the inlet side portion 51 has a pipe body. A recess having an inner peripheral shape coinciding with the outer periphery of 40 is formed,
The tube mounting portion 52 is screwed and fixed to the glue tub in a state where one end of the tube 40 is covered by fitting a concave portion from above.

Therefore, after the tube 40 is placed in the glue tub 4 with its other end abutting against the stopper 55 projecting from the glue bottom 4E, the entrance side 51 of the elastic rubber member 50 is placed.
Is fixed to the inner surface of the glue tub side wall 4A, and the tube 40
Is covered with the tube mounting portion 52 and screwed and fixed in a state of being pressed tightly, so that an L-shape extending from the tunnel-shaped concave portion following the inlet 15 to the opening of the tube end portion in the concave portion of the tube mounting portion 52 is formed. A glue flow path in the shape of a circle is formed in a sealed state. At this time, due to the elastic adhesion force of the elastic rubber member 50, a sealed mounting state without leakage between the members is obtained, and the positioning and fixing of one end of the tube body 40 are completed.

At the time of washing after the gluing operation is completed, if the screw is loosened and the elastic rubber member 50 is removed, the tube 40 is also removed, so that the tube 40 is removed from the lower tube member 41 and the upper tube member 42. At this time, the inner wall surface, which has been disassembled by slide movement and exposed inside the tube, can be easily washed. Further, since the removed elastic rubber member 50 also exposes the inner wall surface that has formed the glue flow path, it can be easily cleaned.

The communication member that communicates the inlet 15 with the one end opening of the tube 40 is not limited to the above-described whole formed of an elastic material as long as it is a member that can be hermetically sealed without leakage of glue. Not something. Also, the shape of the tube 40 is not limited to a substantially rono-shaped cross-section, but it is preferable that the tube 40 be provided with a flat surface so that it can easily contact and fix the inner wall surface of the glue tub at the installation position. It suffices that the shape of the region where the concave portion of the tube body mounting portion abuts on each other matches.

Normally, in washing the inside of the glue tub after the gluing operation, water is supplied into the glue tub by a pump device from a water container storing the washing water instead of supplying the glue from the glue container. Water circulation cleaning is performed in which a discharge hole formed in the center of the bottom of the glue tub is opened, and water is discharged while dropping water in the glue tub into a water container immediately below the discharge hole.

Therefore, also in this embodiment, it is desirable to provide an openable and closable discharge port at the bottom of the glue tub, but in this case, if it is provided closer to the inlet 15 than the center of the bottom of the glue tub. The installation position of the water container is also closer to the inlet 15 side, and the distance from the water container, that is, the pump device 13 to the inlet 15 is shorter than the case where the outlet is provided at the center of the bottom of the glue tub. Can be shortened, and the storage of the device is simplified. In addition, below the glue tub, a roll of a curing tape to be attached to the edge of the back surface of the wallpaper may be pivotally supported near the side wall. In this case, the drain port is located closer to the center than this tape position so as not to hinder the installation of the water container.

[0069]

As described above, according to the wallpaper sizing machine of the present invention, in the glue introduction path for refilling the glue into the glue tub from the outside, the entrance of the glue tub is used as the entrance. Can be easily visually confirmed, and the glue supply operation can be performed much more easily as compared with the conventional glue introduction from the bottom of the glue tub.

Further, since the entrance provided at the side wall position of the glue tub can be set at an appropriate height, the glue in the glue tub does not spill out from the entrance even when this entrance is opened. When glue supply piping from the glue supply pump is attached to the inlet and glue is supplied to the introduction path, even if the piping is removed, as in the case where the inlet is formed on the bottom of the conventional glue tub, The glue remaining in the glue tub does not spill out, and the handling at the time of clearing after the gluing operation becomes easy.
