Description

  The present invention relates to a wallpaper pasting machine for continuously applying glue to the back surface of a sheet-like wall covering material stuck to an indoor wall surface or the like.

  Currently, affixing of wall coverings to interior walls in interior construction of buildings is performed while applying glue continuously to sheet-like wall coverings using a dedicated wallpaper pasting machine at the interior work site. It has become common. As a general configuration of this wallpaper gluing machine, a gluing machine main body mainly composed of an upper structure and a lower structure in which a plurality of rollers are arranged is placed on a pedestal supported by legs. The sheet-like wall covering material (hereinafter also referred to as a cross) sandwiched between the upper and lower structures is conveyed by a roller, and the glue is picked up from the glue tank by a glue scraping roller supported in the glue tank, and used as a gluing roller. It is transferred and applied to the back of the cloth by this gluing roller.

  There are two types of wallpaper pasting machines: a manual type in which an operator pulls out the cloth, and an automatic type in which the glue is driven by a motor to pull out the cloth. As an example of a specific configuration, a cross fed from a raw fabric roll is placed on the lower structure in a state where the tip portion hangs down on the front surface of the main body, the upper structure is closed, and a cross between predetermined rollers of the lower structure and the upper structure is crossed. Is in a state of being sandwiched. In the manual device, the operator holds the tip of the cloth by hand and pulls it forward to rotate a part of the roller while rotating the other roller in conjunction with the gear.

  In an automatic apparatus, a predetermined roller shaft is generally connected to a driving source such as an electric motor and rotated to rotate the other rollers in conjunction with each other via a gear. In either gluing machine, the glue is lifted and transferred from the glue tank while the cloth is transported from the rear side to the front side of the gluing machine body by the rotation of the roller. The configuration is such that the glue is transferred to the back surface, and the cloth is fed out from the front surface with the glue applied.

  In a conventional wallpaper pasting machine, in order to achieve weight reduction and compactness while having high functionality, the effective width length of the roller section of a plurality of rollers is made shorter than that of the conventional pasting machine, and a slitter In order to prevent the part from popping out from the gluing machine main body, a concave mounting opening formed in the width direction of the main body is provided on the rear surface of the gluing machine main body, and the front part of the slitter part is indented into this concave mounting opening. There has also been proposed a pasting machine having a shape that can be attached (see, for example, Patent Document 1).

  In the wallpaper gluing machine, the gluing cloth is then pulled under tension by the drive roller and the leveling roller, and the gluing surface is leveled by the leveling roller and glued to the back side. The cloth is sent to the front of the main unit. While the back side of the cloth is pasted upward by the operator, the tip of the cloth is bent in a U shape and placed on the upper region of the cross receiving plate. Thereby, subsequent cloths are stacked while being folded as they are discharged onto the cloth receiving plate.

  By the way, as for the paste liquid used in the wallpaper pasting machine, it is the mainstream to dilute a commercially available paste liquid with a high concentration or to dilute powdered paste with water, but there is no water supply equipment. There are also sites where water facilities have not yet been established. For this reason, in recent interior construction sites, the paste adjustment process such as dilution work at the site is omitted. Possible glue solutions are already on the market.

  In this case, it is also required that the paste liquid having a concentration capable of being glued is uniformly applied to the cloth. However, since the commercially available paste liquid is left standing for a long period of time, it is in a “tightened state”, compared with the paste liquid immediately after the paste liquid having the same concentration is prepared by a mixing device or the like. Low fluidity.

  For glue liquids with low fluidity, if the glueing speed is set to a certain level, a part of the glue roller that has a large amount of glue liquid will appear on the glue roller. There was a phenomenon that occurred. The reason for the occurrence of such a band-like portion was presumed to be the result of the following phenomenon.

  That is, the glue that has been squeezed to a certain extent by the gap between the glue raising roller and the glue roller is transferred to the glue roller, and the glue liquid adhered by the doctor roller is adjusted to a uniform thickness as the glue roller rotates. At that time, the gluing roller and the doctor roller are arranged with a uniform gap, and the glue liquid that does not pass through the gap is returned to the glue cup.

  When the gap between the gluing roller and the gluing roller is large, the amount of glue transferred to the gluing roller is large, so that the glue liquid that does not pass through the gap with the doctor roller falls into a glue bowl by its own weight. However, when the gap between the glue raising roller and the glue roller is small, there is little glue liquid that does not pass through the gap between the glue roller and the doctor roller, so the glue liquid does not fall into a uniform waterfall on the glue roller surface as a whole, Partly tries to fall down along the glue roller surface.

  However, due to the high-speed rotation of the gluing roller, the glue liquid that tries to fall again on the gluing roller surface arrives in the gap between the doctor roller and the gluing roller, and a portion where a large amount of glue liquid has accumulated in the gap between the gluing roller and the doctor roller The glue with low fluidity generates a force that pushes into the gap due to the rotation of the glue roller and doctor roller, and a part of the glue that adheres to the glue roller partly occurs, which causes blistering during putty construction. It was inferred that a portion where a lot of candy-like paste was attached was generated.

  The glue liquid does not use only a highly concentrated glue liquid. For example, in a wall covering material that needs re-peelability such as processed paper, it is necessary to apply a glue liquid having a low concentration. In order to use a low-concentration glue liquid, the glue liquid cannot be transferred to the glue roller unless the gap between the glue roller and the glue raising roller is made small.

  The present invention can be used with either a thick paste solution or a thin paste solution, and even when a thick paste solution is applied with a thin paste thickness, the transferred paste layer does not have a non-uniform thickness. The aim is to get a chance.

The wallpaper pasting machine according to the first aspect of the present invention includes a pair of pinch rollers that pinch the sheet-like wall covering from the front and back surfaces of the plurality of rollers that are rotationally driven in conjunction with a motor. The wall covering material after the glue liquid applied to the glue roller applied to the glue roller by the glue driving roller that is also driven to rotate while being moved along a predetermined path is reduced to the glue thickness of the gap with the doctor roller. In the wallpaper pasting machine that continuously applies to the back of the machine and discharges it to the front of the main unit,
The glue raising roller is formed with a plurality of fins protruding outward from the roller peripheral surface of the roller,
The glue raising roller and the glue roller are separated from each other so that the tips of the plurality of fins have a gap distance that does not contact the peripheral surface of the glue roller.

  According to a second aspect of the present invention, there is provided a wallpaper pasting machine in which the plurality of fins of the glue raising roller according to the first aspect are arranged in parallel to the roller axial direction at an equal angle on the circumferential surface of the roller. It is a feature.

  A wallpaper pasting machine according to a third aspect of the present invention is characterized in that a plurality of fins of the glue raising roller according to the second aspect are arranged on the circumferential surface of the roller.

  A wallpaper pasting machine according to a fourth aspect of the present invention is characterized in that the rotation of the doctor roller according to any one of the first to third aspects is slower than the peripheral speed of the rotation of the pasting roller. is there.

  The wallpaper pasting machine according to the invention described in claim 5 is characterized in that the rotation of the doctor roller according to claim 4 is 60% slower than the peripheral speed of the rotation of the glue roller.

  The wallpaper gluing machine according to the invention described in claim 6 is a free rotation that transmits the rotation of the gluing roller to the gear of the lower pinch roller as a gear arranged at one end of the doctor roller according to claim 4 or 5. The present invention is characterized in that it has two systems of gears: a gear and a rotating gear that rotates the doctor roller by slowing the peripheral speed of rotation of the gluing roller.

  The present invention can be used with either a thick paste solution or a thin paste solution, and even when a thick paste solution is applied with a thin paste thickness, the transferred paste layer does not have a non-uniform thickness. There is an effect that a machine can be obtained.

It is a perspective view which shows the structure of one Example of the wallpaper pasting machine of this invention. It is a side view of the wallpaper pasting machine of FIG. It is a sectional side view of the wallpaper pasting machine of FIG. It is a side view which shows the state of the gear of the lower structure of the wallpaper pasting machine of FIG. It is a perspective view which shows the state of the gear of the lower structure of FIG. It is a perspective view which shows the structure of the glue raising roller of the wallpaper pasting machine of FIG.

  In the present invention, among a plurality of rollers that are rotationally driven in conjunction with a motor, a pair of pinch rollers that pinch the sheet-like wall covering material from the front and back surfaces are moved along a predetermined path from the rear surface of the main body. The paste liquid applied to the glue roller by the rotationally driven glue raising roller is squeezed to the thickness of the gap between the doctor roller and continuously applied to the back surface of the wall covering material. In the wallpaper pasting machine that discharges to the front, the pasting roller is formed with a plurality of fins protruding outward from the roller peripheral surface of the roller, and the pasting roller and the pasting roller include the plurality of pasting rollers. The tips of the fins are separated so as to have a gap distance that does not contact the peripheral surface of the gluing roller. As a result, a thick paste solution or a thin paste solution can be used, and even when a thick paste solution is applied with a thin paste thickness, a phenomenon in which the thickness of the transferred paste layer is not uniform does not occur.

  Specifically, as described above, a phenomenon in which a portion with a lot of ridge-like paste liquid, such as blistering at the time of putty construction, is caused by the fact that a highly concentrated paste liquid adheres to the glue roller at high speed. In this case, since there is little glue liquid that does not pass through the gap between the glue roller and doctor roller, the glue liquid does not fall in the form of a uniform waterfall on the front of the doctor roller of the glue roller as a whole, partially passing through the glue roller Try to fall into glue paste. However, due to the high speed rotation of the gluing roller, it arrives again in the gap between the doctor roller and the gluing roller, and in the gap between the gluing roller and the doctor roller, a portion where a large amount of glue liquid is accumulated is generated. It was inferred that the rotation of the roller and the doctor roller generated a force to push out into the gap, and part of the glue adhered to the gluing roller was partially generated.

  Therefore, in order to improve the gluing state, the amount of glue liquid to be attached to the gluing roller is increased, the amount of gluing liquid that does not pass through the gap between the gluing roller and the doctor roller is increased, and it is dropped in a uniform waterfall on the front surface of the doctor roller of the gluing roller. I did it. For this reason, the gap distance between the pasting roller and the pasting roller is made larger than the conventional gap distance so that a large amount of glue liquid adheres to the surface of the pasting roller that enters the gap with the doctor roller.

  The preferable gap distance between the glue raising roller and the glue roller depends on the density of the glue liquid, but if the gap distance is increased, a large amount of glue liquid can be supplied to the glue roller. For example, about 0.5 mm to 2 mm, more preferably about 1.5 mm may be secured. However, with this 1.5 mm gap distance, the gap distance between the pasting roller and the pasting roller is larger than before, and a large amount of glue liquid can be supplied. However, a low density glue liquid such as processed paper is used. In this case, it is not possible to increase the amount of glue liquid adhered to the gluing roller. For this reason, the shape of the glue raising roller is not a cylindrical shape but an irregular shape, and a part having a large gap distance and a part having a small gap distance are formed so that the glue can be raised to the glue roller even with a low density glue. .

  As a specific example, a plurality of fins protruding outward from the roller peripheral surface of the roller are formed on the glue raising roller, and the glue raising roller and the glue roller are provided at the tips of the plurality of fins. Therefore, the amount of glue liquid that adheres to the glue roller is increased, and the amount of glue liquid that does not pass through the gap between the glue roller and the doctor roller is increased. It was made to drop into a uniform waterfall on the glue roller surface.

  Specifically, the height of the fin is set to 1 mm, and a portion having a gap of about 0.5 mm with the gluing roller is formed so that the gluing roller can be glued even with a thin gluing. Further, the specific fin configuration is such that a plurality of fins are arranged at equal angles on the circumferential surface of the roller in parallel with the roller axial direction of the glue raising roller. More specifically, if a plurality of fins of the glue raising roller are arranged on the circumferential surface of the roller, it is possible to cope with even a normal thin glue liquid and even a thinner glue liquid. In such a case, the number may be six or more.

  In yet another invention, the rotation of the doctor roller is slower than the peripheral speed of the gluing roller, so that the glue liquid that has fallen along the gluing roller arrives again in the gap between the doctor roller and the gluing roller. It is possible to prevent the occurrence of a non-uniform paste-like paste thickness, such as blistering during putty construction.

  As a specific peripheral speed, it was confirmed that the rotation of the doctor roller is about 60% slower than the peripheral speed of the gluing roller, thereby making it difficult to cause a non-uniform state of the glue-like glue thickness. .

  A typical wallpaper gluing machine rotates other rollers in conjunction with the driving of the gluing roller. For example, in order to slow down the peripheral speed of the doctor roller only, the current doctor roller gear has two systems. Separately, the gear of one system is a free rotating gear, and the rotation of the gluing roller is a system that rotates the gear of the lower pinch roller as in a conventional gluing machine.

  The other gear is a gear that rotates the doctor roller, and this gear may have a gear ratio with the peripheral speed of rotation of the gluing roller being approximately 60%.

The rear side can be opened and closed.

  As the gluing roller 31 is rotated by the drive shaft of a drive source (not shown) in the controller 6, the other rollers to which the rotational motion is transmitted via the gear also rotate and are sandwiched between the upper and lower structures 3 and 4. The cloth C, one end of which is unwound from the original roll R, is conveyed from the rear to the front, and the glue pulled up from the glue ridge 5 when transferred on the glue roller 31 is transferred and applied to the back of the cloth. The

  This gluing roller 31 is pivotally supported on the pivotal support plates on the left and right wall surfaces of the lower structure 3 and is arranged in a lower position where it sinks into the glue basket 5 as much as possible. The glue in the glue basket 5 is transferred to the glue liquid 51 by the glue raising roller 51 in contact with the glue roller 31, and the glue raising roller 51 is pivotally supported on both side surfaces of the glue basket 5 at positions closer to the rear side than the center. Then, the glue in the glue basket 5 is scraped up by rotation and transferred to the glue roller 31.

  The gluing roller 31 is connected to a drive shaft of a controller 6 having an electric motor as a drive source that is detachably attached to the gluing machine main body 1 with a gear. The rotation axis of the gluing roller 31 is the same as the rotation axis of a predetermined roller among the lower pinch roller 32, the doctor roller 33, the leveling roller 34, and the drive roller 43 arranged in the upper structure 4 arranged in the lower structure 3. Are linked through.

  As shown in FIG. 3, the leveling roller 34 has a plurality of tabs 53 for guiding the glued cloth C fed through the leveling roller 34 to the front surface of the gluing machine body 1. The claw stays 54 that are mounted at approximately equal intervals in the direction are attached via mounting tools (not shown) disposed at both ends.

  Note that a lever 39 for driving an eccentric gear that is eccentrically fixed to the rotation shaft of the doctor roller 33 is provided on both sides of the wallpaper pasting machine, and the axis of the doctor roller 33 that is held by the eccentric gear by the lever 39. The end is moved relative to the gluing roller 31, and the relative distance between the doctor roller 33 and the gluing roller 31 is changed so that the amount of gluing attached to the gluing roller 31 can be adjusted.

  A cross receiving bracket 26 is rotatably arranged on the pair of left and right legs 2, and a cross core rod 27 passed through the center of the raw roll R is pivotally supported at the tip of the cross receiving bracket 26. Has been.

  As shown in FIG. 2, the wall covering material (cross) C fed out from the raw fabric roll R is in contact with the leg tension bar 25 laid horizontally on the back surface position of the grounding portion 24 of the cover 23 of the pair of rear legs 22. A pull-in load is applied. Further, a pulling load is applied while being bent by a tension bar group 63 including a first tension bar 61 and a second tension bar 62 installed below the slitter 7, and is conveyed to the slitter 7, on both sides of the cloth. Is disconnected.

2. Lower structure gear FIG. 4 is a side view showing the state of the gear of the lower structure of the wallpaper pasting machine of FIG. FIG. 5 is a perspective view showing a state of the gear of the lower structure in FIG. The gluing roller 31 is driven by the meshing drive of the drive shaft gear of the drive source (not shown) in the controller 6 in FIG. 1 and the gear of the gluing roller 31, and the gluing roller 31 on the non-controller side in FIG. A gear 31g1 fixed to the end of the shaft rotates. As shown in FIG. 5, the gluing roller gear 31 g 1 is a large and small two-stage gear and is connected to two gears 33 g 1 and 33 g 2 fixed to the drive shaft of the doctor roller 33, respectively.

  Of the two gears 33g1 and 33g2 of the doctor roller 33, the gear 33g1 meshed with a larger gear of the glue roller gear 31g1 is fixed to the drive shaft of the doctor roller 33 through a fixing boss of the gear 33g2. A connecting pin group 7g1 for transmitting rotation to a lower pinch roller gear 32g for transmitting the drive of the glue roller to the lower pinch roller 32 and a slitter rotating shaft for rotating the rotary blade of the slitter 7. , 7g2, respectively.

  Of the two gears 33g1 and 33g2 of the doctor roller 33, the gear 33g2 meshed with a smaller gear of the gluing roller gear 31g1 rotates the drive shaft of the doctor roller 33. The gear 33g2 of the doctor roller 33 and the gear 33g2 are meshed so that the gear 33g2 of the doctor roller 33 is about 60% slower than the peripheral speed of rotation of the glue roller 31.

  As described above, the gear of the doctor roller is divided into two systems, and the gear of one system is a free rotating gear, and the system that transmits the rotation of the gluing roller to the gear of the lower pinch roller as in the conventional gluing machine. By rotating the doctor roller slower than the gluing roller by using the gear of the other system with the gear ratio for rotating the gluing roller at a gear ratio with the peripheral speed of the gluing roller being approximately 60%, Even if it becomes a non-uniform state of the ridge-like paste thickness, it can be scraped uniformly by the doctor roller, so that the non-uniform state is eliminated. Specifically, until the viscosity of the paste liquid was increased to 90000 CPS, no portion with poor paste was generated.

3. FIG. 6 is a perspective view showing the configuration of the glue raising roller of the wallpaper pasting machine shown in FIG. As shown in FIGS. 5 and 6, six peripheral fins 52 are provided on the peripheral surface of the glue raising roller 51 disposed inside the glue basket 5. It is formed over the entire length. In the conventional wallpaper pasting machine, the glue raising roller has a cylindrical shape, and the gap between the glue pasting roller rotates with a constant gap, and the glue liquid in the glue basket 5 is transferred to the glue pasting roller.

  However, the roller surface of the glue raising roller 51 of the present embodiment is a gap distance of 1.5 mm from the roller surface of the glue roller 31. In this gap distance, a high-viscosity and high-viscosity glue liquid can be supplied to the gluing roller 31, but with a low-gluing glue liquid, the film thickness itself of the glue liquid adhering to the glue raising roller 51 becomes thin, and the glue roller 31 Liquid film does not touch.

  For this reason, the glue liquid adhering to the glue raising roller 51 by the fins 52 is prevented from moving below the glue raising roller when it is rotated and raised to the glue roller position. The fin 52 prevents the film thickness of the glue liquid adhering to the glue raising roller 51 from being reduced, and the glue liquid can be supplied to the glue roller 31 even with a glue liquid having a low concentration.

  In this embodiment, the number of fins 52 is six. However, when it is assumed that a paste solution having a lower concentration is used, the number of fins 52 may be increased. If not, the number may be reduced. Further, the height of the fins 52 may be determined according to the gap distance between the glue raising roller 51 and the glue roller 31.

  In this embodiment, since the gap distance between the glue raising roller 51 and the glue roller 31 is 1.5 mm, the height of the fin is set to 1 mm so that the tip of the fin does not contact the peripheral surface of the glue roller. The gap distance of 0.5 mm is secured at the shortest.

  In addition, in order to rotate the glue raising roller 51 with the rotation of the gluing roller 31, they are connected by a gear. As shown in FIG. 5, a gluing roller gear 31 g 2 is disposed at the edge of the gluing roller 51. A glue raising roller gear 51g is disposed at the edge of the glue raising roller 51 so as to be connected to the gear 31g2.

  As described above, when the gap distance between the glue raising roller 51 and the glue roller 31 is 1.5 mm, a large amount of glue liquid can be attached to the glue roller, and this is applied to the doctor roller. Therefore, the phenomenon that the thickness of the transferred coating paste layer becomes non-uniform is solved. Moreover, since the glue raising roller is provided with fins, the glue liquid can be satisfactorily supplied to the glue roller even with a low density glue liquid.
