Description

  The present invention relates to a wallpaper gluing machine in which a glue tank is detachably stored in a lower structure of a gluing machine body.

  Currently, in general building interior construction, wall coverings are applied to indoor wall surfaces while applying glue continuously to sheet-like wall coverings using a dedicated wallpaper pasting machine. Yes. As a configuration of such a wallpaper gluing machine, the gluing machine main 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 legs. The glue in the glue tank is pivotally supported in the tank while the sheet-like wall covering material (hereinafter referred to as cross) sandwiched between the upper and lower structures is pulled from the rear of the main body by a roll and conveyed to the front side. A typical example is one that is scooped up by a scraping roll, transferred to a gluing roll, and applied to the back surface of the cloth wall covering material by this gluing roll.

  Each roll is rotatably supported on the left and right side wall plates of the upper structure and the lower structure, and is arranged to rotate in conjunction with each other via a gear or simply follow and rotate on the outside of the side wall plate. In the case of an automatic type wallpaper pasting machine, a rotary motion from a driving source such as an electric motor is transmitted to a gear. The glue tank is normally stored in the lower structure so as to be detachable, and the glue scraping rolls pivotally supported by the glue tank at the predetermined storage position are located on the left and right side walls of the lower structure at the position above the glue tank. It is set so as to maintain a predetermined clearance for good glue transfer with a gluing roll supported on the plate.

  As shown in FIG. 2, the base structure of the main body of the wallpaper pasting machine as described above is a belt-like stay in which the left and right side wall plates 24 that pivotally support each roll and the side wall plates 24 are connected and fixed on the rear surface side of the main body. And a skeleton composed of 25. In such a gluing machine main body 21, a space is secured below the lower structure 22 in order to store the glue tank between the left and right side wall plates 24, and the front side of the main body has an opening for inserting and removing the glue tank. Each roll is pivotally supported in the upper region. Therefore, the gluing machine main body 21 is almost open in the front-rear direction of the main body, which is also the cross conveyance direction.

  In general, a slitter 30 for cutting the side edge of the cloth is often attached to the rear part of the gluing machine body 21 in order to perform gluing after adjusting the width of the cloth to a desired dimension (for example, , See Patent Document 1).

JP 2001-340795 (FIG. 1)

  However, in the conventional wallpaper pasting machine having the main body structure as described above, the mechanical strength of the lower structure including the glue tank storage space in which the basic structure is almost open is not sufficient. With the use of time, the substructure may be distorted or bent, and a good gluing operation may not be maintained.

  Also, as shown in FIG. 2, since there is almost no spatial separation on the rear side of the gluing machine main body 21, when the slitter 30 is attached to the rear of the main body, the slitter 30 and the lower part of the gluing machine main body 21 Adjacent to the glue tank 27 accommodated in the structure 22, in some cases, condensation may occur in the slitter 30 due to the influence of glue moisture in the glue tank. Such condensation may hinder good cutting, such as making the metal components such as the cutting blade of the slitter 30 rust easily or partially loosening the cloth by moistening or wetting it. It was.

  An object of the present invention is to provide a wallpaper pasting machine in which the rigidity of the main body structure is higher than that of the conventional one and the mechanical strength is improved. It is another object of the present invention to obtain a wallpaper pasting machine that can avoid the influence of moisture from the paste tank on the slitter side in the wallpaper pasting machine to which the slitter is attached.

In order to achieve the above object, a wallpaper pasting machine according to the first aspect of the present invention is a sheet drawn from the back of the pasting machine main body by a plurality of rolls pivotally supported between the left and right side wall plates of the pasting machine main body. The glue in the glue tank, which is detachably stored in the gluing machine body, is continuously applied to the back surface of the wall covering material with a gluing roll while transporting the wall covering material to the front side along a predetermined path. In the wallpaper gluing machine, the gluing machine main body is provided with a stay plate for connecting and fixing the left and right side wall plates with a predetermined distance on the rear surface of the gluing machine, and the stay plate is glued from the lower end of the gluing machine main body. the height to a position beyond the upper edge of the housing by glue tank in the machine body, as well as chromatic across the left and right entire width of the gluing machine body, the extending portion bent into the gluing machine body rearwardly above The extending portion draws the wall covering material from the upstream side of the rear part of the gluing machine main body. Parts are those that form a guide surface for guiding the vicinity.

The wallpaper gluing machine according to the invention of claim 2 is a sheet gluing machine drawn from the rear part of the gluing machine main body by a plurality of rolls pivotally supported between the left and right side wall plates of the gluing machine main body. The glue in the glue tank accommodated in the gluing machine main body while being transported to the front side along a predetermined path is continuously applied to the back surface of the wall covering material with a gluing roll, A wallpaper pasting machine in which a slitter having a predetermined wall covering width by cutting a side edge of a wall covering before being pulled into the pasting machine main body is mounted on the rear surface of the pasting machine main body. However, it has a stay plate for connecting and fixing the left and right side wall plates with a predetermined distance, and the stay plate separates the two from each other between the rear surface of the glue tank housed in the gluing machine main body and the front surface of the slitter. Bend to the rear side of the slitter The extending portion forms a guide surface that guides the wall covering having a predetermined width after cutting by the slitter from the upper portion of the slitter to the vicinity of the wall covering pull-in portion at the rear of the pasting machine body. It is what you are doing .

  In the first aspect of the present invention, the stay plate for connecting and fixing the left and right side wall plates for pivotally supporting each roll of the gluing machine main body on the rear surface of the main body extends over the entire left and right width of the gluing machine main body. This stay plate has a side wall plate on the rear surface of the gluing machine body because it has a height dimension from the lower end of the gluing machine body to the position beyond the upper edge of the glue tank stored in the gluing machine body. This will give the corresponding rigidity, improve the mechanical strength of the base structure, make it difficult for the gluing machine body to be bent or distorted even when used for a long time, and can perform gluing work to a good wall covering. There is an effect.

Further, in the present invention, the stay plate has an extending portion that bends to the rear of the gluing machine body above the stay plate, and guides the wall covering material from the upstream side of the rear portion of the gluing machine body to the vicinity of the wall covering material drawing-in section. Since the extending portion that forms the guide surface to be provided is provided, the extending portion can satisfactorily guide the drawing of the wall covering material into the gluing machine main body, and the stay plate can be used for the gluing machine main body. There is an effect that the rigidity imparting action is further improved.

In the invention according to claim 2 , in the wallpaper gluing machine in which the slitter is mounted on the rear surface of the gluing machine main body, the stay plate for connecting and fixing the left and right side wall plates of the gluing machine main body is provided in the gluing machine main body. Since the separation wall that separates the two from each other is formed between the rear surface of the glue tank and the front of the slitter, the stay plate on the rear surface of the main body of the gluing machine provides rigidity to the base structure of the main body of the gluing machine. In addition to improving the mechanical strength by adding, the slitter is separated spatially from the rear surface of the pasting machine body as an isolation wall to block the transfer of moisture in the glue tank to the slitter side. Condensation is prevented and the life of the parts can be kept long, and good wall covering cutting can be maintained over a long period of use.

Further, in the present invention, the stay plate is bent to the rear side of the slitter at the upper side, and guides the wall covering material having a predetermined width after cutting by the slitter from the upper portion of the slitter to the vicinity of the wall covering material drawing portion at the rear part of the pasting machine body. By having an extending portion that forms a guide surface to be guided, the drawing of the wall covering material after cutting into the gluing machine main body is well guided, and the rigidity of the gluing machine main body is improved. At the same time, there is an effect that condensation due to moisture transfer from the glue tank to the slitter is also prevented.

  The present invention is a wallpaper gluing machine, which is used as a stay plate for connecting and fixing the left and right side wall plates for pivotally supporting each roll of the gluing machine main body on the rear surface of the main body. And having a height dimension from the lower end of the pasting machine main body to the position beyond the upper edge of the pasting tank stored in the pasting machine main body.

  Normally, the stay for connecting and fixing the left and right side wall plates of the wallpaper pasting machine is made of a rigid structural member such as metal for the function of becoming the skeleton of the base structure while maintaining the distance between the side walls. However, the stay plate used in the present invention is of course made of a rigid structural member. Therefore, in the present invention, this rigid stay plate has a large vertical width that exceeds the height of the glue tank as described above, which is equivalent to a case where a side wall plate is further provided on the rear surface of the gluing machine body. This will give the machine structure the mechanical strength of the gluing machine body, and the gluing machine body will not be bent or distorted even when used for a long time. Gluing work can be done.

  In addition, such a stay plate is stored in the gluing machine main body when a slitter is attached to the rear part of the gluing machine body in order to perform gluing after cutting the side edge of the cloth and adjusting to a predetermined width. It can also function as an isolation wall that separates the glue tank rear surface and the slitter front surface from each other.

  Such a stay plate as an isolation wall not only improves the rigidity of the base structure, but also separates the glue tank and the slitter spatially, so that the moisture in the glue tank moves to the slitter side. Condensation, which can cause rust on metal components such as slitter cutting blades, is prevented and the life of the parts is kept longer. At the same time, the cloth may be moistened and partially loosened. Therefore, good cross-cutting can be performed even during long-time work.

  If the stay plate in the present invention has a height dimension slightly exceeding at least the upper end of the glue tank, the rigidity imparting effect is sufficiently exerted, but as the upper end of the stay plate extends upward and becomes higher, the rigidity imparting effect is improved. At the same time, the moisture shielding effect on the slitter side is enhanced when the slitter is mounted.

  Therefore, the upper limit of the height dimension of the stay plate can be up to the entire rear surface of the pasting machine main body, but it is also conceivable to provide an extended portion further upward. In this case, the extension part exceeding the main body height may be bent backward, and the bending part extending over the entire left and right width of such a gluing machine body gives the base structure a high rigidity, and the gluing machine body mechanical Improve strength. In addition, the extended part bent toward the rear of the main body is set as a guide surface that is smoothly guided to the rear part of the main body while the back surface of the cloth is in sliding contact by setting the outer surface thereof to have a moderately inclined curved surface. Can be used.

  For example, when the gluing machine main body is composed of a lower structure and an upper structure that can be opened and closed with respect to the lower structure, the lower structure in which the glue tank is stored and the gluing roll is pivotally supported is the base body of the main body Occupies the main part of the structure. Therefore, the substantial upper limit height of the stay plate of such a gluing machine main body is near the upper end position on the rear surface side of the lower structure up to a height position that does not hinder the arrangement and opening / closing of the upper structure. The extending portion extending further upward is bent backward from the height position near the upper end of the lower structure.

  In the pasting machine main body, a cross-drawing portion is a pinch roll composed of a lower pinch roll pivotally supported by the lower structure at the rear part of the main body and an upper pinch roll pivotally supported by the upper structure paired therewith. The lower pinch roll corresponds to the highest position of the lower structure. Accordingly, the bent top of the stay plate extension in the side view of the main body is positioned near the contact portion of the lower pinch roll with the upper pinch roll, and the plate surface from the bent top to the extended portion edge is in the vicinity of the pinch roll. If it forms so that it may become a smooth inclination curved surface from the main body rear side lower part, the guide surface which is smoothly guided to a pinch roll is obtained, while moderate tension | tensile_strength is given to the back surface of a cloth | cross along this curved surface.

  When the slitter is mounted on the gluing machine main body, this extended portion is located above the slitter and guides the cloth that has been cut and fed from the top of the slitter to the vicinity of the pinch roll of the gluing machine main body. What is necessary is just to form a surface.

  Needless to say, the stay plate of the present invention is effective when the wallpaper pasting machine is an automatic type or a manual type.

  As one embodiment of the present invention, a wallpaper pasting machine having a slitter attached to the rear part of the main body will be described below. FIG. 1 is a side perspective view showing a schematic configuration of a wallpaper pasting machine according to the present embodiment. In FIG. 1, the pedestal and the leg on which the gluing machine main body is placed are omitted. In this embodiment, a wallpaper pasting machine in the case where the slitter 10 is mounted on the rear part of the pasting machine main body 1 is illustrated.

  The gluing machine main body 1 of the present embodiment has the same configuration as the conventional one except for the roll arrangement other than the base structure. That is, the gluing machine main body 1 is mainly composed of an upper structure 3 and a lower structure 2 in which a plurality of rolls are arranged, and an upper structure 3 that can be opened and closed with respect to the lower structure 2 and the lower structure 2. While the cloth C sandwiched between the two is pulled from the rear of the main body with a roll and conveyed to the front side, the glue in the glue tank 7 stored in the lower structure 2 is glued up and supported in the tank. It is picked up by the roll 8 and transferred to the gluing roll 14, and the gluing roll 14 continuously coats the back surface of the cloth C.

  The base structure of the gluing machine main body 1 is mainly constituted by the lower structure 2. The skeleton of the lower structure 2 includes a lower pinch roll 12, a gluing roll 14, a doctor roll 13 for adjusting the amount of gluing of the gluing roll 14, and left and right side wall plates 4 that respectively support the leveling roll 15 at both ends. It comprises a stay plate 5 that connects and fixes the left and right side wall plates with a predetermined distance on the rear surface of the main body.

  The upper structure 3 is attached to the lower structure 2 so that the rear surface side is the center of rotation, and the front structure is provided with upper left and right side wall plates that rotate so as to be openable and closable with respect to the lower structure 2. The upper pinch roll 16, the press stay 17, and the drive roll 18 that are pivotally supported by the upper cover 9 are covered with the upper lid 9 between the upper left and right side wall plates.

  In the present embodiment, the stay plate 5 is made of a metal plate and has a rigidity that covers the entire width of the main body from the lower end to the upper end of the lower structure 2 and bends upward to the rear of the main body. The extended portion 6 is provided.

  This stay plate 5 forms a part of a strong skeleton as a rear wall plate having a height dimension extending over almost the entire upper and lower surfaces of the lower structure 2, and gives rigidity to the base structure of the gluing machine main body 1. The strength is improved. Therefore, the gluing machine body 1 is unlikely to be bent or distorted, and a good gluing operation can be maintained even when the apparatus is driven for a long time.

  Further, when the slitter 10 is mounted on the rear part of the pasting machine main body, an isolation wall that spatially separates the slitter 10 between the front surface of the slitter 10 and the rear surface of the glue tank 7 that is housed in the lower structure 2. Also works. That is, the stay plate 5 as an isolation wall prevents the moisture of the glue in the glue tank 7 from moving toward the slitter 10, and thus causes rusting of metal components such as the cutting blade 11 in the slitter 10. Condensation is prevented and the life of not only the components but also the slitter itself can be extended. Further, there is no possibility of partial bending due to the cloth C being cut becoming wet or wet, and good cross cutting can be performed even when used for a long time.

  Further, the extended portion 6 of the stay plate 5 has a bent top portion 6a in the vicinity of the pinch roll (lower pinch roll 12, upper pinch roll 16) which is a cross drawing-in portion at the rear of the main body, and the extended portion edge 6b. Is set to be positioned above the slitter 10 on the lower rear side of the main body, and forms a guide surface having a smooth inclined curved surface from the bent top portion 6a to the extended portion edge 6b.

  Accordingly, after the cloth C cut out from the upper part of the slitter 10 is slid along the guide surface and is moderately tensioned by the curved surface of the guide surface, it is smoothly guided to the vicinity of the pinch roll. Then, it is sandwiched between the upper and lower pinch rolls (16, 12), drawn into the inside of the main body, and conveyed to the front side of the main body.

  The stay plate 5 does not necessarily need to be flat at a portion below the bent portion and substantially serving as a rear wall plate of the lower structure 2. For example, as shown in FIG. 1 of the above-described embodiment, the design and shape of the actual wallpaper pasting machine, such as having a concavo-convex shape according to the front shape of the slitter 10 to be actually mounted and the state of the mounting portion It suffices to respond appropriately.

It is a schematic block diagram of the wallpaper pasting machine by one Example of this invention. It is a schematic explanatory drawing which shows an example of the conventional wallpaper pasting machine, (a) is the perspective view which looked at the pasting machine main body from the front side, (b) is the perspective view which looked at the pasting machine main body from the back side. is there.
