As shown in FIG. 4, the conventional wallpaper sizing machine includes an upper structure 2 and a lower structure 3 constituting a sizing machine main body 1, and a leg 4 for supporting the sizing machine main body 1 at a predetermined height. A table (cross roll) 5 for suspending a wall material (cross) 7 wound in a roll shape on the rear side of the gluing machine main body 1, a glue tub 6 provided in the lower structure, It mainly includes a plurality of rolls 9 to 15 arranged in the structure 2 and the lower structure 3 via gears, and a control box 17 for controlling the driving of the plurality of rolls 9 to 15. A hinge 21 for connecting the upper structure 2 and the lower structure 3 to each other is provided on the front side of the sizing machine main body 1, and the upper structure 2 is connected to the rear side of the sizing machine main body 1. A hook (not shown) for fixing the lower structure 3 to each other is provided. [0003] The incorporation of the plurality of rolls is performed by feeding tension to the upper pinch roll 13a and the cloth 7 that constitute a pinch roll for taking in the cloth 7 into the main body 1 in the upper structure 2. Are arranged in parallel with each other, and are directly or via a solid lubricating ring in a hole formed in a side plate of the upper structure 2. Further, a cross 7 is provided between the upper pinch roll 13a and the drive roll 12.
The presser rolls 14 that follow and rotate by pressing from above are arranged in parallel. In the lower structure 3, a lower pinch roll 13b, a gluing roll 9, and a pinch roll for taking in the cloth 7 into the main body 1 are provided.
The leveling rolls 11 are arranged in parallel, and a doctor roll 10 and a gluing roll 15 are arranged in contact with the gluing roll 9. The gluing roll 9 is the lower structure 3
Bearing by a ball bearing pressed into the side plate of
The lower pinch roll 13b, the doctor roll 10 and the leveling roll 11 are respectively supported in a hole formed in the side plate of the lower structure 3 directly or through a solid lubricating ring. It is directly bearing by an engineering plastic bearing plate (not shown) mounted on the side. Further, the control box 17 comprises:
The control box includes a motor that is detachably attached to one end of the plurality of rolls 9 to 15 and that internally includes a motor that rotationally drives the plurality of rolls 9 to 15 and a control device that controls the driving of the motor. An operation panel 17a provided on the side of the device 17 can provide control information including an operation command and an operation condition to the control device. An encoder (not shown) for measuring the number of rotations of a plurality of rolls 9 to 15 driven by the motor is housed in the side cover 2a of the upper structure 2. Are output to the control box 17 via the plug 20. When performing the gluing operation using the wallpaper gluing machine configured as described above, the operator first operates the dials 23 attached to the front faces of both ends of the main body 1 to make the doctor roll. The relative distance (gap) between the sizing roll 9 and the sizing roll 9 is changed, and adjustment is performed so that a desired amount of glue adheres to the cloth 7 by the sizing roll 9. It should be noted that a scale indicating a relative distance movement amount with respect to the gluing roll 9 is displayed on the surface of the dial 23 . FIGS. 5A and 5B show the dial 23.
FIGS. 3A and 3B are schematic configuration explanatory diagrams illustrating an internal state of a positioning adjustment mechanism 22 that is operated when is operated, where FIG. 3A is a schematic side view and FIG. 3B is a schematic top view. The dial-type positioning and adjusting mechanism 22 is housed in a gear box 1 a provided on a side surface of the main body 1. As shown in FIGS. 5A and 5B, a positioning adjustment mechanism 22 includes a dial 23, a first bevel gear 24,
It is mainly composed of a second bevel gear 25 and a sector gear 26. The sector gear 26 is rotatably mounted on the side plate of the lower structure 3 at the top of the sector and is eccentric from the center of rotation of the sector gear 26. In the position, the shaft end 10 of the doctor roll 10
a is held by the sector gear 26 so as to be relatively rotatable. When the dial 23 is rotated, the positioning and adjusting mechanism 22 having the above-described structure rotates the shaft 23a.
, The first bevel gear 24 rotates, and the second bevel gear 25 meshed with the first bevel gear 24 also rotates. Then, the sector gear 26 meshed with the second bevel gear 25 rotates. As a result, the doctor roll 10 whose shaft end is held at a position eccentric from the center of rotation of the sector gear 26.
Moves in the direction of arrow A, whereby the glue roll 9
The relative distance (gap) between the head and the doctor roll 10 can be changed. After operating the positioning adjustment mechanism 22,
The operator performs the trial operation of the gluing roll 9 for positioning the reference position of the cloth 7 and eliminating the glue unevenness in the gluing, and opens the gluing machine main body 1 to perform the initial setting, so that the cloth 7 is moved from the cross roll 5 to the cloth 7. Is pulled out from the rear side of the main body, and hangs to the front side through the space between the upper and lower pinch rolls 13a and 13b. After closing the gluing machine main body 1, the motor housed in the control box 17 is driven by the initial set amount. I do. As a result, the rolls connected by the gear rotate at a predetermined peripheral speed ratio, and the glue in the tub adhered to the sizing roll 9 by the sizing roll 15 is separated from the sizing roll 9 by the operation of the dial 22. Is adjusted to a desired amount of glue by the doctor roll 10 in which the relative distance of the glue roll 9 is changed. Applied. The glued cloth 7 is then pulled by the drive roll 12 and the leveling roll 11 under appropriate tension and emerges from the front of the main body. At this time, the peripheral speed of the leveling roll 11 The difference provides a leveling action of the glue surface. When the cloth 7 comes to the front by the initial set amount, the motor 18 is temporarily stopped, and the unnecessary cloth at the end is cut by the cutter along the cutter guide 16 to complete the initial setting. Next, the operator operates the control box 17.
When the desired cross length is input from the operation panel 17a of the main body and the motor is driven in the same manner, the cloth 7 of the desired length glued to the back surface of the entire length comes out from the front surface of the main body, and is cut along the cutter guide 16. And is folded by an operator and deposited on the front tray 8. After the cloth 7 having the desired length is deposited on the front tray 8, the motor is stopped once again, and the desired cloth length is again input from the operation panel 17a of the control box 17, and the motor 18 is driven. This work has been repeated. However, in the above-mentioned conventional wallpaper sizing machine, a scale indicating the relative distance (gap) between the sizing roll 9 and the doctor roll 10 is provided on the surface of the dial 23. Therefore, in order to accurately recognize the scale, it is necessary to visually check the scale on the front surface of the dial 23. That is, since the positioning and adjusting mechanisms 22 are separately and independently attached to both ends of the main body 1, dials 23 for operating the respective positioning and adjusting mechanisms 22 are also separately provided on both front ends of the main body 1. When the operator operates the positioning and adjusting mechanism 22 independently, the operator operates the dial 23 on the front surface of the dial 23 of one of the positioning and adjusting mechanisms 22 and then operates the other positioning and adjusting mechanism 22. However, there is a problem that the user has to move to the front of the other dial 23 and operate the other dial 23. Further, since the positioning and adjusting mechanism 22 provided in the conventional wallpaper gluing machine uses bevel gears 24 and 25, the wallpaper gluing machine itself is in the width direction (perpendicular to the moving direction of the cloth 7). In the direction in which it is performed). The shaft end of the doctor roll 10 provided in the conventional wallpaper gluing machine is held at a position eccentric from the center of rotation of the sector gear 26 so as to be relatively rotatable. By the rotation of the doctor roll 10, a force due to sliding friction is applied to the doctor roll shaft end holding portion of the sector gear 26 to the sector gear 26, and this force is applied to a position eccentric from the rotation center of the sector gear 26, There is also a problem that the sector gear 26 rotates in the rotation direction of the doctor roll 10 due to the moment, and the relative distance (gap) between the gluing roll 9 and the doctor roll 10 is changed from a set value. The present invention has been made in view of the above problems, and has as its object to provide a wallpaper sizing machine which can easily operate a positioning adjustment mechanism for changing a relative distance between a sizing roll and a doctor roll. And Another object of the present invention is to provide a wallpaper sizing machine that can easily visually check the scale provided on the positioning adjustment mechanism. Still another object of the present invention is to provide a wallpaper sizing machine capable of reducing the thickness in the width direction (the direction orthogonal to the moving direction of the wall covering). It is another object of the present invention to provide a wallpaper sizing machine in which the relative distance between the sizing roll and the doctor roll does not fluctuate during the sizing operation. According to the first aspect of the present invention, there is provided a wallpaper sizing machine according to the first aspect of the present invention, in which a plurality of rotating rolls disposed in a main body section form a sheet. While pulling the wall covering from the rear of the main body into the interior,
Wallpaper that moves along a predetermined path inside the main body and continuously applies the glue in the glue tub disposed below the main body to the back surface of the wall covering material by the gluing roll of the plurality of rotating rolls. In the sizing machine, a doctor roll that adjusts the amount of glue adhered to the sizing roll by changing the facing interval with the sizing roll, and a positioning adjustment mechanism that changes the rotation center position of the doctor roll, The positioning adjustment mechanism includes a vertically rotatable lever member attached to both ends of the main body portion, and a display mechanism that indicates the position of the lever member.
Attached to the front of the main body, the display mechanism is provided on a side of the handle, on the front of the main body, the handle protrudes from the front of the display mechanism, The lever member inhibits rotation of the lever
A rotation prohibiting unit, wherein the rotation prohibiting unit is provided with the display unit.
Penetrate the nut part formed in the structure and the lever member
And a bolt that can be fitted into the nut portion . The wallpaper gluing machine according to the first aspect of the present invention includes a positioning adjustment mechanism, and the positioning adjustment mechanism includes a vertically rotatable lever member, And a display mechanism. The lever members are attached to both ends of the front part of the main body of the wallpaper gluing machine, and the display mechanism indicates the position of the lever members. That is, the lever member is a member for operating the positioning and adjusting mechanism. By simply moving the lever member up and down, the positioning and adjusting mechanism is easily operated, and the relative distance between the gluing roll and the doctor roll is changed. Can be changed. Therefore, it is possible to operate the positioning adjustment mechanism with both hands at one place in the front part of the main body without moving to the both ends of the main body of the gluing machine as in the prior art and operating the dial. Become. Further, since the lever member protrudes from the front of the display mechanism, even when the lever member is viewed obliquely with respect to the lever member, the position of the lever can be accurately viewed. become. Further, since the lever member is a thin member in the width direction of the wallpaper sizing machine (in the direction perpendicular to the moving direction of the wall covering material), the thickness of the lever member is smaller than that of a conventionally used bevel gear. In addition, it is possible to reduce the thickness of the wallpaper gluing machine in the width direction (the direction orthogonal to the moving direction of the wall covering material). In the wallpaper gluing machine according to the present invention, the lever member includes a rotation inhibiting means for inhibiting the rotation of the lever. That is, in order to prevent the relative gap (gap) between the gluing roll and the doctor roll from fluctuating, the sector gear may be prevented from rotating. To do this,
The rotation of the lever member meshing with the sector gear is inhibited when desired by the rotation inhibiting means, and thereby the rotation of the sector gear is also inhibited. As a result, it is possible to prevent the relative distance between the gluing roll and the doctor roll from being changed without permission during the gluing operation. In the wallpaper gluing machine according to the present invention, the rotation prohibiting means includes, for example, a nut formed on the display mechanism, and a bolt that penetrates through the lever member and can be fitted into the nut. Is done. That is, since the lever member protrudes from the front part of the display mechanism, a hole is made in a side part (side surface) of the lever member at a position facing the display mechanism so that a bolt can pass therethrough. And The display mechanism has a nut portion at a position facing the hole. As a result, when a bolt is inserted through the hole and the bolt is inserted into the nut portion, the rotation of the lever member is prevented by the bolt. Therefore, since the lever member cannot rotate, the sector gear also cannot rotate. As a result, the relative distance between the gluing roll and the doctor roll is prevented from changing during the gluing operation. FIG. 1 is a schematic structural explanatory view of a wallpaper sizing machine according to an embodiment of the present invention. The difference from the conventional wallpaper gluing machine is that a dial 23 conventionally attached to both front surfaces of both ends of the main body 1 for operating the positioning adjustment mechanism 22 is used as a lever 31 (handle portion 31a). Position (relative distance between gluing roll 9 and doctor roll 10)
(A display mechanism) 32 is provided. Note that the same parts as those in the conventional example are denoted by the same reference numerals, and description thereof will be omitted. FIGS. 2A and 2B are schematic structural explanatory views showing the internal state of the positioning adjustment mechanism 30 of the wallpaper gluing machine according to one embodiment of the present invention, wherein FIG. 2A is a schematic side view, and FIG. It is a schematic front view. As shown in FIGS. 2A and 2B, the positioning adjustment mechanism 30 according to the present embodiment has a handle 31 at one end.
a, a lever 31 having the other end formed in a toothed portion (gear) 31b and rotatable in a vertical direction with a bolt 31c as a fulcrum for attachment to the side surface of the gluing machine main body 1;
And a scale plate 32 provided on the front side of the gluing machine main body 1 and on the side of the handle 31a.
The mounting structure between the sector gear 26 and the doctor roll 10 is the same as that of the conventional example shown in FIG. In the positioning and adjusting mechanism 30 of the embodiment constructed as described above, when the handle 31a is rotated lightly in the vertical direction, the tooth profile 31b rotates in the opposite direction to the handle 31a. Accordingly, the sector gear 26 rotates toward the front side or the rear side of the gluing machine main body 1. As a result, the axial end of the doctor roll 10 held by the sector gear 26 is relatively moved in the direction of arrow A,
The relative distance (gap) between the adhesive and the gluing roll 9 changes. As described above, in the present embodiment, FIG.
As shown in (b), the operation of the positioning adjustment mechanism 30 is operated by the lever 31.
At one location on the front surface of the main body 1 without moving to the opposite ends of the body 1 with both hands.
0 can be manipulated. In addition, as shown in FIGS. 2 (a) and 2 (b), since the lever 31 protrudes from the front surface of the scale 32, the lever 31 can be easily seen even when the lever 31 is viewed from an oblique direction. Can be visually observed. Further, since the lever 31 having a small thickness is used in the width direction of the gluing machine (the direction orthogonal to the moving direction of the cloth 7), the thickness of the gluing machine in the width direction can be reduced. it can. Specifically, when the positioning adjustment mechanism 22 is stored in the conventional wallpaper gluing machine, the width of the storage cover is required to be 51 mm at one end, but can be 35 mm in the present invention. That is, the width can be reduced by 32 mm at both ends. [0044] Further, since the formation of the other end of the lever 31 sector gear 26 and meshes with gear portion (gear) to 31 b, compared with the conventional apparatus, it is possible to reduce the number of parts. In this embodiment, the case where the present invention is applied to a wallpaper gluing machine with a motor has been described.
The cloth 7 is pulled into the sizing machine main body 1 by a human operator,
It goes without saying that the present invention can also be applied to a so-called manual type wallpaper gluing machine that applies glue to the back surface of the cloth. FIGS. 3A and 3B are schematic explanatory diagrams showing a lever rotation inhibiting mechanism (rotation inhibiting means) 40 according to an embodiment of the present invention. FIG. 3A is a schematic side view, and FIG. It is a schematic front view. As shown in FIGS. 3A and 3B, the lever rotation inhibiting mechanism 40 is provided with holes 41 formed at a plurality of positions of the scale 32, and operating bolts that are screwed into and penetrate the side surfaces of the lever 31. 42. By turning the operation bolt 42 by hand, the tip protruding from the lever 31 can be made to penetrate into the opposing hole 41 of the scale plate 32.
1 can be prohibited when desired. By providing the lever rotation inhibiting mechanism 40 configured as described above, during the gluing operation, the sector gear 26 rotates freely, and the relative distance (gap) between the gluing roll 9 and the doctor roll 10 is increased. ) Does not change. As described above, the present invention has an effect that the scale indicating the relative distance between the gluing roll and the doctor roll can be easily visually observed. The present invention also has the effect that the size of the sizing machine itself can be reduced in the width direction (the direction orthogonal to the moving direction of the wall covering). The present invention also has an effect that the number of parts can be reduced. Further, in the present invention, since the rotation inhibiting means is provided on the lever member, there is also an effect that the relative distance between the gluing roll and the doctor roll does not fluctuate freely during the gluing operation.
