Description

  The present invention relates to a wallpaper pasting machine to which a glue tank is detachably mounted.

  Currently, it is common to apply wall coverings to interior wall surfaces in interior construction of buildings while applying glue continuously to sheet-like wall coverings using a dedicated wallpaper pasting machine on site. It has become. Recently, the spread of automatic wallpaper pasting machines is increasing. As a general configuration of the wallpaper gluing machine, the gluing machine body mainly composed of an upper structure and a lower structure in which a plurality of rolls are arranged is placed on a pedestal supported by a leg part, The sheet-like wall covering material (hereinafter referred to as “cross”) sandwiched between the upper and lower structures is conveyed by a roll, and the glue is picked up from the glue tank and transferred to the glue roll by a glue scraping roll supported in the glue tank. Then, the pasting roll is applied to the back surface of the cloth wall covering material.

  There are two types of wallpaper pasting machines: manual type and automatic type. As an example of the specific configuration, the upper structure is placed on the lower structure with a cloth fed from the roll roll placed on the front of the main body. In the state where the cloth is sandwiched between the predetermined rolls of the lower structure and the upper structure with the closed, the manual device rotates the other part of the roll by holding the tip of the cloth with the hand and pulling it forward. The roll is rotated in conjunction with a gear, and in an automatic device, the roll of a predetermined roll is connected to a drive source such as an electric motor and rotated to rotate other rolls in conjunction with the gear. In both cases, the glue that is lifted and transferred from the glue tank through the glue scraping roll in the middle of conveying the cloth from the rear side to the front side of the gluing machine main body by rotating the roll is transferred to the top of the roll. Glue is transferred to the cross back surface from the roll in the vicinity, the cross has a structure that come fed from the front with glue-coated state.

  Normally, the glue tank that stores glue is installed in the lower structure of the main body of the wallpaper glue machine, but if it is configured to be detachable, it can be removed during transport and storage and the glue machine body It is easy to handle, and it is possible to efficiently supply glue and clean the glue tank by separating the glue tank from the main body.

  Such paste tank insertion / removal is performed on the inner wall surface of the gluing machine main body facing the outer side of the glue tank, actually on the pivot side plate on which each roll on the main body side is pivotally supported. In general, the guide is roughly guided by sliding to the bottom surface of the glue tank along a protruding guide portion partially provided from the side to the rear (see, for example, Patent Document 1).

  On the other hand, in order to more easily transport the wallpaper pasting machine, the apparatus is being made lighter and more compact. As one of the methods, first, each roll arranged in the gluing machine main body is made to have a small diameter. When a roll having a reduced roll diameter is arranged in this way, the core spacing between rolls can be reduced, and the overall apparatus width can be reduced.

Utility Model Registration No. 2569045 (page 4, FIG. 2)

  However, as described above, when the roll diameter is reduced and the apparatus width is reduced, the size of the glue tank mounted in the gluing machine body is also reduced. As a result, the amount of glue contained in the glue tank is reduced, and the effective amount of gluing tends to be reduced.

  In order to cope with this, when paste is filled to the full capacity of the glue tank, the glue moves in the rotation direction in the tank along with the rotation of the glue scraping roll supported in the glue tank. There is a risk that the glue will partially increase and overflow from the tank. Therefore, in order to secure the capacity on the side where the glue is moved in the glue tank and to make effective use of the glue tank volume, the axis support position of the glue scraping roll is set to the center of the glue basket width direction (cross conveyance direction). Will be arranged closer to one side.

  In addition, since a general wallpaper pasting machine operates on the front side of the pasting machine main body, that is, on the cross output side, a glue is provided so that the remaining amount of glue in the glue tank can be easily visually confirmed. It is desirable that the movement of the glue by the rotation of the scraping roll is on the cross output side. Therefore, from the above, the pivot support position of the glue scraping roll is located farther from the center of the glue tank, that is, arranged closer to the cross input side on the rear surface side of the gluing machine body.

  On the other hand, the gluing roll that is pivotally supported on the gluing machine main body side is placed so as to be sunk inside the gluing tank as much as possible when the apparatus is driven, so that the gluing roll itself for transferring the glue to the gluing roll is used. Since the diameter can be reduced, and a larger effective capacity can be secured for storing the paste in the paste tank, the shaft support position is set further downward.

  However, when the gluing roll is placed in the gluing tank in this way, it is necessary to supply gluing when the amount of gluing remaining in the gluing tank is reduced or lost during the work. The glue tank must be pulled out from the cloth output side with the roll placed in the lower position, but even if the glue tank can be supplied only by partially pulling out the glue tank, the glue tank is simply pulled horizontally. However, the glue scraping roll interfered with the lower end portion of the gluing roll, and the glue tank could not be pulled out smoothly.

  Also, if the glue tank is inserted and installed after the assembly of the glue machine body at the beginning of work, the upper edge of the rear edge of the glue tank hits the glue roll already placed in the work state position and may be damaged. Therefore, the glue tank must be installed before the roll is installed, and the procedures and settings for assembling and setting the equipment are limited. If the assembly procedure is changed, it must be reassembled. There was also a possibility that the work process would become complicated due to the shortage of time.

  Some of the conventional wallpaper pasting machines are also provided with a guide section for the glue tank, but this guides the insertion / removal movement roughly, and makes it lightweight and compact as described above. In accordance with the change in the arrangement of the gluing roll on the lower side, there has been no apparatus provided with a guide mechanism sufficient to enable smooth insertion and removal of the glue tank without causing any interference between the rolls.

  Further, the position where the glue scraping roll can transfer the glue to the glue roll most efficiently is the position near the back of the glue tank and slightly behind the lower end of the glue roll from its lower end. . This is because the glue scraping roll usually scrapes the glue on the front side of the glue tank and transfers it to the upper glue roll. Since it returns to the front side and remains without being used for transfer, if the back side space where the glue accumulates is reduced by setting the pivot support position of the glue scraping roll as close to the tank as possible, it will be wasted. This is because the amount of paste can be reduced and the amount of effective paste can be increased.

  However, the pivot support position of the glue scraping roll as close to the glue tank as possible is such that the position where it contacts the glue roll is on the rear side of the glue roll. In the insertion method in which the glue is simply pushed into the back, the interference of the glue-raising roll with the glue roll becomes very large. It was the limit possible for the arrangement.

  In view of the above problems, an object of the present invention is to provide a wallpaper gluing machine in which a gluing tank is detachably mounted in a gluing machine main body, with respect to a gluing roll that is pivotally supported on the gluing machine main body side. A wallpaper pasting machine equipped with a glue tank guide mechanism that allows smooth and partial insertion and removal of the glue tank without interference from the glue tank and the glue scraping roll supported in the glue tank. It is to provide. In addition, the present invention provides a wallpaper pasting machine that can smoothly guide the glue tank so that the glue scraping roll is arranged at a predetermined position where the glue in the glue tank can be efficiently transferred to the glue roll. With the goal. A further object of the present invention is to provide a wallpaper pasting machine that can ensure a stable state at the paste tank insertion completion position or paste supply position and that can be operated safely and hygienically.

In order to achieve the above object, a wallpaper pasting machine according to the first aspect of the present invention provides a sheet-like wall covering material drawn from the rear surface of the pasting machine main body to the front side while feeding the sheet-like wall covering material to the front side. Glue accommodated in the glue tank is placed in contact with the gluing roll at a position behind the lowest end of the gluing roll on the gluing machine body side . In a wallpaper gluing machine that rakes up with a raising roll, transfers it to a gluing roll, and continuously applies gluing to the back surface of the wall covering material with the gluing roll
A glue tank guide mechanism for guiding insertion / removal of a glue tank inserted from the front side toward the rear side into the gluing machine body,
The glue tank guide mechanism is provided with rail means provided on at least one inner wall surface of the right and left side surfaces of the gluing machine body facing in a direction orthogonal to the wall covering material traveling direction, and facing the inner wall surface of the gluing machine body. A cylindrical protrusion that is provided on the outer surface of the glue tank and slides or rotates in the rail means;
The rail means has a path for guiding the glue tank along a path not interfering with the glue roll together with the glue scraping roll pivotally supported in the glue tank via the cylindrical protrusion, and having a width of the glue tank moving width. It has a fixing part that continuously has substantially the whole area, and restricts further movement of the cylindrical protrusion at the insertion completion position of the glue tank ,
The glue tank includes a first cylindrical protrusion provided on the outer side of the tank and a second cylindrical protrusion provided closer to the tank than the first cylindrical protrusion. , Having a third columnar protrusion provided near the front end of the tank,
A first rail for guiding the first cylindrical protrusion, and a second rail for guiding the second cylindrical protrusion different from the first rail. And
The third columnar protrusion has a corner at least on the front lower side, and the rail means is a step where the corner of the third columnar protrusion is fitted in the state where the paste tank is completely inserted. Is provided near the front end of the rail .

According to a second aspect of the present invention, there is provided a wallpaper pasting machine according to the first aspect of the present invention, in which the predetermined amount is set in the middle of the insertion path guided along the rail means of the glue tank. At the glue supply position, at least one cylindrical protrusion is shallow and a recess into which the lower part is fitted is provided in the middle of the corresponding rail .

A wallpaper pasting machine according to a third aspect of the present invention is the wallpaper pasting machine according to the first or second aspect , wherein the glue tank is predetermined in the middle of the insertion path guided along the rail means. At the glue supply position, the rear edge of the tank opening is located behind the central axis hanging position of the doctor roll that is pivotally supported in the glue machine main body in order to adjust the glue amount according to the distance to the glue roll. It has an opening shape.

  In the wallpaper pasting machine according to the first aspect of the present invention, the paste tank is pivotally supported in the glue tank or the glue tank by the glue tank guide mechanism with respect to the glue roll that is pivotally supported on the glueing machine main body side. There is an effect that the partial and overall insertion / removal movement of the glue tank can be smoothly performed without interference of the raising roll.

  Further, in the wallpaper pasting machine according to the second aspect of the present invention, the rail means includes first and second rails, and each rail is provided on the outer surface of the glue tank, and the first cylindrical protrusion near the tank. And the second cylindrical protrusion on the front side of the tank, and the corresponding protrusions on the front side of the tank. The part including the roll is also smoothly inserted / removed along a track that does not interfere with the gluing roll.

  Further, in the wallpaper pasting machine according to the third aspect of the present invention, there is provided a first rail as a rail means, the first cylindrical projection near the tank back provided on the outer surface of the glue tank by the rail, and the rail. Both the second cylindrical protrusion on the front side of the tank is guided, and the rear upper edge of the tank and the glue scraping roll do not interfere with the gluing roll, and the back part of the glue tank is also on the front side with a single rail. The close part is also smoothly inserted and removed.

  In the wallpaper pasting machine according to the fourth aspect of the present invention, the lower corner of the front side of the third columnar protrusion provided near the front end portion of the outer surface of the paste tank is connected to the paste tank main body of the paste tank. Since it is fitted to the stepped part near the rail front end in the insertion completed state, this fitting part serves as a stopper to return to the front side after the glue tank is inserted, vibration during gluing work, etc. As a result, it is possible to avoid the risk of the glue tank rattling or sliding out toward the front side, and it is possible to perform safe and stable work.

  Further, in the wallpaper pasting machine according to the fifth aspect of the present invention, the tank opening rear end edge is behind the center axis hanging position of the doctor roll at a predetermined glue supply position where the glue tank is partially pulled out to the near side. By using the glue tank with the opening shape located at the position, the glue dripping from the doctor roll during glue supply work is received behind the glue tank, so that the floor surface does not have to be soiled with glue. .

  In the present invention, the glue tank is moved by sliding the cylindrical protrusion provided on the outer surface of the glue tank within the rail means provided on the inner surface of the side of the gluing machine body facing the outer surface of the glue tank. By carrying out the rotation, the glue tank is inserted into and removed from the gluing machine main body along a path corresponding to the track of the rail means.

  This rail means has a continuous track over almost the entire area of the glue tank moving width, and this track has both a glue tank moving path and a glue scraping roll supported on the inside. It is set so as to follow a path that does not interfere with the gluing roll arranged below the gluing machine main body, and further restricts further movement of the cylindrical projection at the glue tank insertion completion position by the fixing portion. Therefore, in the present invention, there is no problem over the entire process from the paste tank insertion start position to the insertion completion position in which the cylindrical protrusion is fitted to the end of the rail means on the front side of the main body. As a result, continuous and smooth movement is performed, and the glue tank is guided to the correct mounting position in the gluing machine main body.

  According to the guide mechanism of the present invention, the paste tank can be inserted and removed through a path that does not interfere with the glue roll, so that interference with the glue roll when the glue tank is inserted is too large and difficult with the conventional wallpaper glue machine. It is possible to realize the rear shaft support of the tank, which is arranged in contact with the glue roll of the glue scraping roll at the rear position from the lowermost end without any problem, increasing the effective glue amount in the glue tank for more efficiency. Glueing work can be done. In the present invention, the back side and the back side of the glue tank are the back side of the gluing machine main body, and the front side and the front side of the glue tank are the front side of the gluing machine body.

  The simplest configuration that can realize smooth movement of the glue tank along a path that does not interfere with the glue roll is to input wall covering material at least at the back of the glue tank outer surface, that is, on the rear side of the glue machine main body. If one cylindrical protrusion provided on the side is configured to slide or rotate along one rail of a predetermined track, the upper end edge of the glue tank mainly does not interfere with the glue roll. The movement of the portion near the glue tank is controlled so as to move.

  In addition, it is preferable to control the entire insertion / removal movement of the glue tank so as to stabilize the smooth movement along the predetermined path. That is, not only the first cylindrical protrusion provided at the back of the outer surface of the adhesive tank as described above, but also the second cylinder closer to the front than the first cylindrical protrusion of the outer surface of the adhesive tank. As a result, the glue tank can be controlled so that not only the back part of the glue tank but also the front part of the tank including the glue scraping roll is controlled to move along a track that does not interfere with the glue roll. The overall movement control is performed.

  The movement control of the glue tank back side portion by guiding the first cylindrical protrusion as described above, particularly the movement avoiding the interference with the gluing roll at the upper edge of the tank rear portion, and the second cylindrical protrusion are guided. As a rail means that can perform both the movement control of the front side portion of the glue tank including the glue scraping roll by first, a first rail on which the first cylindrical protrusion slides or rotates is provided, Apart from this, there may be mentioned a configuration in which a second rail is provided for the second cylindrical protrusion to slide or rotate.

  Also, if the track design can smoothly guide both the first and second cylindrical projections without causing the glue tank and glue scraping roll to interfere with the gluing roll, both projections can be slid within one rail. It may be configured to move or rotate. In the case of the configuration in which the first and second cylindrical protrusions are guided by this single rail, the tank back side portion and the front side portion thereof continuously move along the same track, The movement of the entire glue tank becomes smoother.

  In addition, as a fixing part for restricting further movement of the cylindrical protrusion at the position where the glue tank is completely inserted in the glue machine main body, for example, the rear part of the rail (the rear side of the glue machine main body) is used. A configuration having a dead end shape in which the cylindrical protrusion abuts at the paste tank insertion completion position is simple and desirable.

  Furthermore, it is preferable to provide a releasable lock mechanism for locking and fixing the glue tank to the glue machine main body at the insertion completion position so that the glue tank mounting state can be more stably maintained during the gluing operation. .

  As such a locking mechanism, a mechanism for fixing the glue tank may be provided separately from the rail means, but rail means such as a fitting means serving as a stopper is provided between the outer surface of the glue tank and the rail. If the member configuration is utilized, the design becomes simple. For example, a third columnar protrusion is provided near the front end of the outer surface of the glue tank, and a step is provided near the rail front end. The corner on the lower front side of the third columnar protrusion at the position where the paste tank is completely inserted. The structure which a part fits into a level | step-difference part is mentioned.

  If such a fitting means is provided, when the glue tank is inserted into the gluing machine main body and pushed into the insertion completion position, the third columnar projection falls on the stepped portion, and the corner on the lower front side of the projection. Since the part abuts against the vertical wall surface of the stepped part, the movement of the glue tank toward the front side is restricted. The risk of rattling or sliding out to the near side is also prevented.

  When pulling out the glue tank, such as when supplying glue during work or at the end of the work, the front end of the glue tank is lifted up slightly and the third columnar protrusion is just laid on the stepped portion. The stop state can be easily released and the glue tank can be pulled out smoothly.

  The shape of the third columnar protrusion has at least a corner at a lower position in the front side direction of the tank, and the corner may match the angle of the stepped portion. The corner is also 90 degrees. It may be any polygonal column that has a corner at the lower front side, and the simplest example is a square column, but the third columnar projection also moves within the rail at the front end, albeit slightly. Therefore, it is desirable that the portion on the rear side of the tank is generally tapered and rounded so that the vertical width is small so that it is difficult to be caught at that time.

  The glue tank guide mechanism of the present invention mainly composed of the rail and the cylindrical protrusion as described above is one of the left and right sides of the gluing machine (facing in a direction perpendicular to the wall covering material traveling direction). The structure with only one side and the other side with a conventional level guide can make the glue tank insertion / removal smooth without interfering with the gluing roll. It is good also as a structure guided along a predetermined route.

  Also, normally, when the glue in the glue tank has to be reduced and supplied during the gluing operation, the glue tank is partially pulled out to the front side, and from the front area of the tank opening coming out from the gluing machine body In many cases, glue is supplied into the tank. In the gluing operation, a doctor roll that is pivotally supported on the back of the gluing roll on the gluing machine body is in contact with the gluing roll to remove excess glue and adjust the amount of glue.

  Accordingly, since the glue is also adhered to the doctor roll, as described above, when the glue tank is partially pulled out to supply the glue, the floor surface is directly exposed under the doctor roll. When the glue that has adhered to the doctor roll dripping during the glue supply, the floor surface is soiled as it is.

  Therefore, in the present invention, the glue tank has a tank opening shape in which the rear edge of the opening of the glue tank is located behind the central axis drooping position of the doctor roll at a predetermined glue supply position. Since the glue dripping from the roll is received behind the glue tank, it is not necessary to soil the floor surface with glue, and cleaning up after the work becomes easy.

  As an opening shape of such a glue tank, the entire width may be widened backward from the conventional glue tank, but at least the opening is widened so that the rear end of the tank moves backward by a necessary distance. This is sufficient, and it is not always necessary to increase the volume of the entire glue tank.

  The glue tank guide mechanism and the glue tank of the present invention as described above are effective for both manual and automatic types as long as the glue tank is a type of wallpaper pasting machine to which the glue tank can be inserted and removed. Needless to say.

  As a first embodiment of the present invention, wallpaper paste provided with a glue tank guide mechanism having two rails of a first rail and a second rail as rail means on one of the left and right sides of the gluing machine main body The attached machine is shown in FIGS. FIG. 1 is a schematic side perspective view of a gluing machine main body showing the configuration of the glue tank guiding mechanism of the wallpaper gluing machine. FIG. 2 is a schematic configuration diagram showing a glue tank guide mechanism part, where (a) is a perspective view of a rail part, and (b) is a perspective view of a glue tank provided with a cylindrical protrusion. FIG. 3 is a schematic perspective view showing a state immediately after the start of the glue tank insertion, and FIG. 4 is a partial front view showing the glue tank insertion completed state. FIG. 5 is a partially enlarged view showing the lock mechanism of the glue tank.

  The wallpaper pasting machine in the present embodiment is an example in which the basic configuration other than the glue tank guide mechanism has the same roll arrangement as that of a conventional general wallpaper pasting machine. That is, the pasting machine main body 1 is composed of an upper structure 2 and a lower structure 3 on which a plurality of rolls are pivotally supported and a wall covering material (cross) is sandwiched therebetween, and a glue tank 5 in which glue is stored. It is inserted into the lower structure 3 from the front side of the gluing machine main body.

  As the rolls rotate, the gluing roll 4 that continuously abuts against the back surface of the cloth conveyed forward from the back side of the gluing machine body 1 while rotating is applied to the left and right side walls of the lower structure 3. This shaft support plate is pivotally supported so as to be arranged in a lower position where it sinks into the glue tank 5 as much as possible. Further, a glue scraping roll 6 that scrapes up the glue in the glue tank 5 by rotation and transfers it to the glue roll 4 is pivotally supported on both side surfaces of the glue tank 5 at positions farther from the center.

  In this embodiment, two pairs of groove-shaped rails and cylindrical projections that slide or rotate in the rails are provided as rail means that mainly constitute the glue tank guide mechanism. The cylindrical protrusion has an outer diameter that substantially matches the groove width of the rail. A first cylindrical protrusion 10 is provided on the outer surface on one side of the glue tank 5 at the back of the tank, and the first cylindrical protrusion 10 is continuously provided over almost the entire region in the movement width direction. The first rail 11 for guiding and mainly controlling the insertion / removal movement path of the back part of the glue tank 5 is arranged on the inner surface of the side wall of the lower structure 3 which is also a roll shaft support plate facing the outer surface of the glue tank. Set up in a continuous orbit.

  The first rail 11 has a predetermined tank tank that can be inserted and moved through a path in which the rear upper end edge of the glue tank 5 is disposed at a predetermined position without interfering with each other through the lower end of the glue roll 4. It has an inclined orbit.

  Further, a second cylindrical protrusion 20 is provided on the outer surface of the glue tank 5 at a position below the first cylindrical protrusion 10 in front of the first cylindrical protrusion 10, and the second cylindrical protrusion 20 is continuously guided. Thus, the second rail 21 for mainly controlling the insertion / removal movement path of the front portion of the glue tank 5 is provided at a position below the first rail 11 on the inner surface of the side wall. The second rail 21 guides the second cylindrical protrusion so that the glue scraping roll 6 is disposed at a predetermined position without interfering with the glue roll 4, and the first cylindrical protrusion 10. The movement along the path that avoids interference with the gluing roll 4 at the back part of the glue tank including the upper edge at the rear part of the glue tank by the guide of the first rail 11 can be reinforced and maintained more stably on the front side of the tank. Have an orbit.

  Further, the rear ends of the first and second rails (11, 21) are arranged at the first and second ends in order to restrict further movement of the cylindrical protrusion at the position where the paste tank 5 is inserted. The fixed portion (12, 22) having a dead end shape against which the cylindrical protrusion (10, 20) abuts.

  According to the glue tank guide mechanism as described above, when the glue tank 5 is started to be mounted, first, if the first cylindrical protrusion 10 is fitted and introduced into the front opening end of the main body of the first rail 11, it remains as it is. By simply pushing in the glue tank 5, the insertion movement of the glue tank 5 along the set path proceeds smoothly.

  Immediately thereafter, as shown in FIG. 3, the second cylindrical protrusion 20 is naturally fitted and introduced into the main body front side opening end of the second rail 21. Therefore, if the glue tank 5 is further pushed in, there is no problem, and each cylindrical protrusion (10, 20) advances in the corresponding rail (11, 21) and reaches the fixed part (12, 22). It can be seen that the above movement is restricted and the insertion completion position of the glue tank 5 has been reached.

  In this embodiment, as shown in FIG. 4, when the glue tank 5 reaches the insertion completion position, the auxiliary cylindrical protrusion 13 that fits into the opening end on the front side of the main body of the first rail 11 is provided. Further provided on the outer surface of the glue tank 5. Since the front portion of the glue tank 5 is supported by the first rail 11 via the auxiliary cylindrical protrusion 13, the attachment state of the glue tank 5 to the lower structure 3 becomes more stable.

  Furthermore, in this embodiment, by providing a releasable lock mechanism 30 at the lower part of the glue tank 5, the glue tank 5 is securely fixed at the insertion completion position, and the glue tank 5 is positioned by vibration during operation. It was set as the structure which can prevent shifting.

  The locking mechanism 30 has a configuration in which the latching claw 31 projects by pushing down the operation piece 32 projecting outward, and the latching claw 31 is immersed by pushing up the operation piece 32. When the latching claw 31 is projected at the insertion completion position of the glue tank 5, it is latched on the lower frame 9 of the lower structure 3, thereby preventing the glue tank 5 from moving back in the front drawing direction.

  As described above, according to the glue tank guide mechanism in the present embodiment, the insertion movement of the glue tank 5 is continuously guided from the start until reaching the completion position, and the path is prevented from interfering with the gluing roll 4. Smooth and smooth. This is the same when the glue tank 5 is taken out and when it is partially pulled out to supply glue.

  In the present embodiment, the second tank 21 is placed in the middle of the second rail 21 at the partial pull-out position so that the paste tank 5 can maintain a relatively stable state in the partial pull-out state when the paste is supplied. The cylindrical protrusion 20 is shallow and is provided with a recess 23 that fits downward. When the second cylindrical protrusion 20 is fitted in the recess 23, the glue tank 5 is lightly positioned with the front side of the glue tank 5 slightly tilted downward. The two cylindrical protrusions 20 return from the recesses 23 onto the second rail 21 track, and the movement proceeds.

  As a second embodiment of the present invention, a wallpaper pasting machine provided with a glue tank guide mechanism having one rail as rail means on one of the left and right sides of the pasting machine main body is shown in FIGS. Show. FIG. 6 is a schematic side perspective view of the gluing machine main body showing the configuration of the glue tank guide mechanism of the wallpaper gluing machine, and FIG. 7 is a schematic side perspective view showing the usage state of the gluing machine main body. Yes, (a) shows a state where the glue tank is in the glue supply position, and (b) shows a state where the glue tank is completely inserted in which the gluing operation is performed. The gluing machine main body in this embodiment has the same basic configuration as that shown in the first embodiment except for the glue tank and its guide mechanism, and the common member configuration is indicated by the same reference numeral.

  In this embodiment, as the rail means mainly constituting the glue tank guide mechanism, one groove-like rail 40, the first cylindrical protrusion 51 that slides or rotates in the rail 40, and the second The cylindrical protrusion 52 was provided. These cylindrical protrusions (51, 52) have an outer diameter substantially matching the groove width of the rail 40.

  On the outer surface on one side of the glue tank 50, a first cylindrical protrusion 51 is provided near the back of the tank, and a second cylindrical protrusion 52 is provided closer to the front. In this embodiment, the arrangement position of the glue scraping roll 6 is set to a pivotal support position near the glue tank that is in contact with the glue roll 4 slightly above and behind the lowest end.

  The rail 40 continuously guides the first cylindrical protrusion 51 over almost the entire region in the movement width direction thereof, and mainly controls the insertion / removal movement path of the back portion of the glue tank 50, particularly the glue. The tank rear upper end edge 55 guides to a predetermined position without interfering with the gluing roll 4, and guides the second cylindrical protrusion 52 to glue the front side portion of the gluing tank 50 including the glue scraping roll 6. 4 is continuously guided along an insertion / removal movement path that does not interfere with the movement.

  In this rail 40, the rear upper edge 55 of the glue tank 50 just passes through the lower end of the glue roll 4 and is arranged at a predetermined position without interfering with each other, and the glue scraping roll 6 interferes with the glue roll 4 Instead, it has a predetermined inclined track that allows the glue tank to be inserted and moved in a path that is arranged at a position that is in contact with the pasting roll 4 on the upper rear side from the lowermost end.

  In addition, the rear end of the rail 40 is a fixed portion 41 having a dead end shape in which the first cylindrical protrusion 51 is abutted and further movement is restricted at the position where the paste tank 50 is inserted.

  According to the glue tank guide mechanism as described above, when the glue tank 50 is started to be mounted, the first cylindrical protrusion 51 is first fitted into the front opening end of the main body of the rail 40, and the glue tank 50 is left as it is. By simply pushing in, the insertion movement of the glue tank 50 along the set route proceeds smoothly.

  Immediately after that, the second cylindrical protrusion 52 is fitted and introduced into the main body front opening end of the rail 40. Therefore, if the glue tank 50 is further pushed in, there is no problem, and the first and second cylindrical protrusions (51, 52) sequentially advance in the rail 40, and the first cylindrical protrusion 51 is fixed. It can be seen that the movement reaches the portion 41 and further movement is restricted, and the insertion completion position of the glue tank 50 has been reached.

  In this embodiment, a step 42 is formed in the vicinity of the front end of the rail 40. As shown in FIG. 7B, when the glue tank 50 reaches the insertion completion position, the step 42 is formed. A third columnar protrusion 53 into which the front lower corner 54 is fitted is provided near the front end of the outer surface of the glue tank 50. Since the movement of the glue tank 50 to the near side is restricted by the fitting state of the third columnar protrusion 53 and the stepped part 42, the glue tank 50 does not move back after the insertion is completed. The risk that the glue tank 50 slides out from the front side of the gluing machine main body 1 due to the vibration of the apparatus during the gluing operation and glue is spilled or the glue tank 50 itself falls is prevented.

  When partially pulling out the glue tank 50 to the glue supply position for replenishing glue, or when taking out the glue tank 50 from the gluing machine body 1 after finishing the gluing operation, the front end of the glue tank 50 is slightly lifted to By simply riding the portion 54 on the stepped portion 42, the fitting state between the two is released. If the glue tank 50 is pulled out as it is, the first and second cylindrical protrusions (51, 52) is guided to the front side, and the glue tank 50 is smoothly guided to the front side.

  In the present embodiment, the angle of the step portion 42 is approximately 90 degrees, and the corner portion 54 fitted to the step portion 42 is also approximately 90 degrees. However, the third columnar protrusion 53 is inserted into the rail 40. In order to avoid catching during the movement, the taper shape is such that the vertical width on the rear side is small, and the corners other than the corner 54 are rounded.

  Further, in this embodiment, as shown in FIG. 7A, the rail 40 is provided at the partially pulled out position so that the glue tank 50 can be kept relatively stable in the partially pulled out state when the glue is supplied. In the middle of this, a concave portion 43 in which the second cylindrical projection 52 is shallowly fitted downward is provided.

  When the second cylindrical protrusion 52 is fitted in the recess 43, the glue tank 50 is lightly positioned with the front side of the glue tank 50 slightly tilted downward, and the glue tank protrudes from the front surface of the gluing machine body. Glue can be easily supplied into the tank from 50 front opening areas. When the glue supply is completed, the second cylindrical projection 52 returns from the recess 43 to the rail 40 track by pushing the glue tank 50 backward with a little force, and the movement is advanced. The insertion can be completed again.

  Further, in this embodiment, the opening of the glue tank 50 is widened to the rear side as compared with the conventional glue tank, and the rear upper edge 55 is a position where the doctor roll 14 hangs down at the center axis of the glue supply position. It should be located behind X. As a result, even when the glue tank 50 is partially pulled out to the near side when the glue is supplied, the glue dripping from the doctor roll 14 can be received in the rear region of the glue tank opening. The floor will not get dirty.

Next, wallpaper pasting work was performed using the wallpaper pasting machine of the present example having the above-described configuration, and the effective glue capacity and the effective glue length were measured. The results are shown in Table 1 in comparison with the case where the wallpaper pasting operation was performed by two conventional types of wallpaper pasting machines. Note that the pasting machine of the conventional type is a model of the same level as that of this example, and the work was performed on the same width (0.92 m) of wallpaper with the same amount of paste (135 g / m ² ). . However, the conventional gluing machine has no guide mechanism such as rail means, and the bottom of the glue tank is supported by a glue tank receiver provided on the inner surfaces of the right and left side walls of the gluing machine body. The raising roll is set to a position directly below the gluing roll at the lowermost end.

  As shown in the results of Table 1, according to the wallpaper pasting machine of this example, the paste effective capacity and the paste effective length are significantly larger than those of the conventional type even with the same total capacity of the paste tank. It became clear that it was improved. The glue tank 6 of the present embodiment has almost the same total capacity as that of the conventional type 1, but the capacity is increased by the amount of the rear upper end edge of the opening widened. However, this increase is only 0.2 L, and the length by which the increase can be glued to the wallpaper of the width with the application amount is about 1.6 m, with the paste weight being about 200 g. . On the other hand, the increase in the effective gluing length is 10 m. Therefore, the effective gluing length of the wallpaper gluing machine of the present embodiment, that is, the significant increase in the gluing effective capacity, It is clear that it is due solely to the arrangement of the glue scraping roll 6 rather than due to a change in shape.

  In this way, in order to set the glue scraping roll 6 to the glue tank back pivot support position where an efficient gluing operation can be performed, even if it is arranged to contact the gluing roll 4 on the rear upper side from the lowermost end, this embodiment is carried out. In the example of the wallpaper pasting machine, the glue tank 50 can be smoothly inserted to a predetermined arrangement position along the path where the glue scraping roll 6 does not interfere with the pasting roll 4 by the guide mechanism composed of rail means. .

  In addition, as shown in the second embodiment, the fitting between the corner portion of the third columnar protrusion and the step portion for locking and fixing the glue tank to the gluing machine main body at the insertion completion position is used. The locking mechanism including the locking means is not limited to the case where the rail means includes only one rail, but is effective even in the case of a glue tank guide mechanism including two first and second rails. Further, the above-mentioned glue tank having a shape in which the opening is widened to the rear side and the upper end edge of the rear part is located rearward from the drooping position of the upper doctor roll central axis at a predetermined glue supply position is also applicable to any rail means. It can be used.

  Therefore, a glue tank guide mechanism having two rails, a first rail and a second rail, is provided as rail means, and the corner of the third columnar protrusion is used as a lock mechanism for locking and fixing the glue tank at the insertion completion position. FIG. 8 shows a wallpaper pasting machine provided with a locking means by fitting between a step and a step formed on the front end of the rail, as Embodiment 3 of the present invention.

  That is, in the wallpaper pasting machine according to the present embodiment, the first rail 60 and the second rail 63 provided on the inner surface of the side wall of the lower structure 3 of the pasting machine main body 2 as the rail means, and the glue. A first cylindrical protrusion 71 that is provided near the tank on the outer surface of the tank 70 and that slides or rotates in the first rail 60, and a lower position on the near side of the first cylindrical protrusion 71. A glue tank guide mechanism is mainly composed of a second cylindrical protrusion 72 that is provided and slides or rotates in the second rail 63.

  The first rail 60 continuously guides the first cylindrical protrusion 71 over almost the entire region in the movement width direction, and mainly controls the insertion / removal movement path of the back part of the glue tank 70. The glue tank 70 has a predetermined track that allows the glue tank to be inserted and moved in a path that is arranged at a predetermined position without interfering with each other by passing through the bottom edge of the gluing roll 4 just behind the upper edge 75 of the glue roll 4. Is.

  The second rail 63 mainly controls the insertion / removal movement path of the front portion of the glue tank 70 by continuously guiding the second cylindrical protrusion 72, and the glue scraping roll 6 becomes the glue roll 4. While being arranged at a predetermined position without interference, interference with the glue roll 4 at the glue tank back portion including the glue tank rear upper end edge 75 by the guide of the first cylindrical protrusion 71 and the first rail 60 is provided. It has a continuous track that can reinforce and maintain movement along the path to be avoided more stably on the front side of the tank.

  In addition, the rear ends of the first and second rails (60, 63) are first and second, respectively, in order to restrict further movement of the cylindrical projection at the position where the glue tank 70 is inserted. The fixed protrusions (61, 64) having a dead end shape against which the cylindrical protrusions (71, 72) abut.

  Furthermore, in this embodiment, as a locking mechanism for releasably engaging and fixing the glue tank 70 at the insertion completion position, a step 62 formed near the front end of the first rail 60 and the outside of the glue tank 70 are provided. And a third columnar protrusion 73 provided near the front end of the side surface. The third columnar protrusion 73 is provided with a corner portion 74 on the lower front side. When the glue tank 70 reaches the insertion completion position, the corner portion 74 is fitted to the stepped portion 62, whereby the glue portion 70 is glued. The tank 70 is restricted from moving toward the front side and does not return after the insertion is completed. Further, the risk that the glue tank 70 slides out from the front side of the glue machine main body 1 due to the vibration of the apparatus during the gluing operation and glue is spilled or the glue tank 70 itself falls is prevented.

  When partially pulling out the glue tank 70 to the glue supply position for replenishing the glue or when taking it out from the gluing machine body 1 after the gluing operation is finished, the front end of the glue tank 70 is slightly lifted to By simply placing the portion 74 on the stepped portion 62, the fitting state between the two is released. If the glue tank 70 is pulled out as it is, the first and second rails (60, 63) are moved along the first and second rails (60, 63). The second cylindrical protrusions (71, 72) are guided to the front side, and the glue tank 70 is smoothly guided to the front side.

  According to the glue tank guide mechanism as described above, when the glue tank 70 is started to be mounted, first, the first cylindrical protrusion 71 is fitted and introduced into the front opening end of the first rail 60 on the front side of the main body. If 70 is pushed in, the glue tank 70 is smoothly inserted and moved along the set route. Immediately after that, the second cylindrical protrusion 72 reaches the main body front side opening end of the second rail 63, and if the glue tank 5 is further pushed there, it enters from the opening end and is introduced. Each cylindrical protrusion (71, 72) advances in the corresponding rail (60, 63) to reach the fixed part (61, 64), and further movement is restricted, and reaches the position where the paste tank 70 is completely inserted. You can see that

  In the present embodiment, the second cylindrical projection 72 is provided in the middle of the second rail 63 with a recess 65 into which the second cylindrical projection 72 is shallowly fitted, and the second cylindrical projection 72 is fitted into the recess 65. The glue tank 70 is slightly positioned with the front side of the glue tank 70 from which the glue tank 70 has been partially pulled out slightly inclined. The position of the glue tank 70 at this time is set as the glue supply position, and the glue tank 70 is maintained in a relatively stable state in a partially pulled out state so that the glue can be supplied easily. The glue tank 70 in the glue supply position is in a state in which the second cylindrical projection 72 returns from the recess 65 to one track of the second rail 63 and can be moved again only by pushing in with a little force. And advanced to the insertion completion position.

  Furthermore, in this embodiment, the glue tank 70 has a shape in which the opening is widened to the rear side so that the rear upper edge 75 is located behind the central axis hanging position of the upper doctor roll 14 at the glue supply position. Thus, the glue dripping from the doctor roll 14 during the glue supply operation can be received.

  According to the glue tank guide mechanism in the above embodiment, the insertion movement of the glue tank 70 is continuously guided from the start until reaching the completion position, and the path is smooth and smooth with avoiding interference with the glue roll 4. It is a thing. In particular, in the glue tank guide mechanism for guiding the first and second cylindrical protrusions (71, 72) corresponding to the first and second rails (60, 63), respectively, as in this embodiment. Compared to the glue tank guide mechanism that is guided by only one rail as shown in the second embodiment, the configuration is complicated, but the inclination in the vertical direction is smaller than the track of the single rail. Accordingly, since the vertical movement during movement of the glue tank 70 is small, all insertion / removal movements such as insertion / removal of the glue tank 70 and partial withdrawal for supplying glue can be performed more smoothly.

  In the present embodiment, the case where the engaging means including the third columnar protrusion 73 and the stepped portion 62 as a locking mechanism for locking and fixing the glue tank 70 is configured by the first rail 60 is shown. Of course, the second rail 63 may be used, or both the first and second rails (60, 63) may be used.

  Further, the engaging means including the third columnar protrusion and the stepped portion 62 as described above exhibits a sufficient locking effect of the glue tank 70 against the vibration of the apparatus during the gluing operation. When the attachment machine is transported with the glue tank inserted, if the vehicle is vibrated vigorously, the glue tank 70 is largely rattled and the third columnar protrusion 73 rides on the stepped portion 62, and the glue tank 70 is glued. There is a risk of detachment from the main unit. Therefore, it is desirable to further provide pressing means for more reliably reinforcing the locked state of the glue tank 70 in response to such intense vibration during transportation.

  Such a pressing means may be a mechanism that presses the glue tank 70 downward from above so that the third columnar protrusion 73 does not ride on the stepped portion 62. For example, as shown in FIG. 9, the structure in which the pressure tank 80 presses the glue tank 70 at the insertion completion position in the lower structure 3 at the position of the front upper edge 76 is simple.

  The pressing member 80 is attached to a claw stay 8 to which a claw for guiding the pasted wallpaper sent through the leveling roll 7 to the front surface of the gluing machine body 1 is attached. An elastic structural member made of polyacetal resin or the like is desirable. The pressing member 80 can be slid along the claw stay 8 if it is pushed in the left-right direction by a protrusion 82 with a non-slip 81 provided on the front surface. When the pressing member 80 is moved to the end of the claw stay 8, The lower portion rides on the front upper edge 76 of the glue tank 70 and presses the glue tank 70 downward.

  Due to the pressing state of the glue tank 70 of the pressing member 80, the third columnar protrusion 73 is also pressed downward and the riding on the stepped part 62 is restricted. The positive locking state of 70 is maintained. Further, when the glue tank 70 is taken out before the work is started, if the pressing member 80 is moved in the center direction on the claw stay 8, the pressing state of the front upper edge 76 is released, and the glue tank 70 is slightly opened. It is possible to lift the glue tank 70 out of the lower structure 3 by lifting it upward and removing the third columnar protrusion 73 from the engaged state with the stepped portion 62.

  Such a pressing mechanism is not limited to the configuration in which the pressing member 80 is slidably mounted on the claw stay 8. For example, the front upper edge 76 of the glue tank 70 on the inner wall surface of the gluing machine body 1 on which each roll is pivotally supported. Near the front of the glue tank 70 so as to be releasable, such as one having a pressing member so that it can be selectively moved between a position where the front upper edge 76 is pressed and a retracted position which does not interfere with insertion / removal of the glue tank 70. What is necessary is just to be able to press an upper end edge area | region with respect to the engaging part with the level | step-difference part 62 of the 3rd columnar protrusion 73. FIG.
