Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention mainly relates to a wallpaper gluing machine for continuously applying glue to the back surface of a long wall covering material when sticking a sheet-like wall covering material to an indoor wall surface.

[0002]

[Prior Art]

 A typical wallpaper gluing machine has a main body equipped with a glue tub between a stand that suspends rolled wall covering (cloth) and a cloth receiver that receives the cloth after gluing. It is configured as a manual or automatic gluing machine with a motor by incorporating various roll devices into its main body. The various rolls are installed by attaching ball bearings to the gluing rolls, which have a relatively large weight, to the frame plates (bearing plates) made of aluminum, etc., located on both sides of the glue tub, and to the other rolls from Luron metal. Bearing bushes made of, for example, plastic metal (Duracon) are press-fitted to receive the shaft of each roll, and a gear is attached to the shaft end of each roll so that each roll works in a predetermined peripheral speed ratio. ..

[0003]

[Problems to be solved by the device]

 In the conventional wallpaper gluing machine, each roll is supported by a bearing plate made of metal, so the molding process of the bearing plate is troublesome, and the bearings are required for disassembly and reassembly such as assembly and cleaning. The installation of bushes and bushes and the operation of split taps are complicated, and especially because the metal plates that make up the bearing plates have been made thin to reduce weight, the bearing plates vibrate and resonate during operation, resulting in work problems. In addition to the loud noise, there was a risk of problems such as meandering and wrinkling due to vibration in the passing wall covering, and unevenness in gluing.

An object of the present invention is to provide a wallpaper gluing machine capable of easily forming a bearing plate, assembling a roll, disassembling and reassembling, and suppressing vibration of the bearing plate during operation.

[0005]

[Means for Solving the Problems]

 In the wallpaper gluing machine according to the first aspect of the present invention, while the sheet-shaped wall covering material is guided to a predetermined path by a plurality of rolls, the glue in the glue tub is continuously applied to the back surface of the wall covering material by the gluing roll. In the wallpaper gluing machine for transferring to the above, the above-mentioned problems are achieved by pivotally supporting each roll by a pair of frame side plates made of engineering plastic.

In the wallpaper gluing machine according to the second aspect of the present invention, the frame side plate is made of an engineering plastic plate by monomer casting, for example, a monomer casting nylon.

In the wallpaper sizing machine according to the third aspect of the present invention, at least a part of each roll is directly supported by the hole formed in the frame side plate.

Further, in the wallpaper gluing machine according to a fourth aspect, the frame side plate is composed of an engineering plastic plate having a layer containing a lubricant in at least a bearing hole portion.

Further, in the wallpaper gluing machine according to a fifth aspect, at least the bearing hole portion of the frame side plate is made of engineering plastic to which lubricant powder is added.

[0010]

[Action]

 In the wallpaper sizing machine according to the present invention, each roll such as a sizing roll, a doctor roll, a leveling roll, a drive roll, an upper and lower pinch roll for taking in, and a press roll is a pair of engineering plastics located on both upper sides of the glue tub. Since it is pivotally supported by the frame side plate, for example, a doctor roll that is relatively loaded or a heavy gluing roll can be attached to the frame side plate by simply attaching the louron metal bush and ball bearings as needed. Since the bearing can be directly received in the through hole, the number of parts used, such as the bearing bush, can be greatly reduced, and the frame side plate as the bearing plate is required by monomer casting such as reaction injection molding and slight cutting. In addition to the fact that it can be easily molded into a shape, One in which re-assembly it is extremely simple. In addition, since each roll is pivotally supported by the plastic frame side plate, not only can the weight of the main body of the gluing machine be reduced, but the vibration that accompanies the roll rotation during operation is effectively absorbed by the frame side plate. Large vibrations will not be transmitted to the covers and pedestals of the attached machines, and the vibration noise during operation will also be reduced, and it will be possible to prevent the wall material from meandering, wrinkling, and non-uniform glue. Further, the frame side plate may be provided with a lubricant such as molybdenum disulfide or fluororesin as a layered or in-resin additive in at least its bearing portion, and in some cases, a solid lubricant ring may be attached.

 A preferred embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention in the case of an automatic wallpaper gluing machine equipped with a motor, and FIG. 2 is a main part of the same. FIG. 3 is a side view showing the configuration of the glue tub and the roll structure, FIG. 3 is a plan view corresponding to the arrow AA in FIG. 2, FIG. 4 is a view along the arrow BB in FIG. 2, and FIG. It is a C arrow line view.

First, referring to FIG. 1, a wallpaper gluing machine 1 includes a main body 3 having a glue trough supported by legs 2 and a cross roll 4 rotatably supported by a pedestal on the rear surface of the main body 3. , And a cross receiver 5 arranged on the front side of the main body 3.

The wall covering material, that is, the cloth 7, is wound around the cloth roll 4, and the main body 3 is hinged at the rear side to the upper lid portion 6 that can be opened and closed on the inside of the glue tub. It is passed under the upper lid 6. The upper lid portion 6 is provided with an operation panel 65 in the central portion for numerically displaying the length measurement result measured by a rotary encoder 64 (FIG. 4) described later and for giving a drive control command for the motor 8. A cutter guide 36 for guiding the cutter when the cloth is cut in the width direction is provided on the front surface of the gluing machine main body 3.

As shown in FIGS. 2 to 5, the main body 3 and its upper lid 6 each have a pair of engineering plastic frame side plates 30a, 30b and 60a, 60b as left and right bearing plates. However, the outer sides thereof are covered with covers 38a, 38b, 68a, 68b, respectively. A motor cover 39 is further attached to one of the lower covers 38b, and the roll drive motor 8 is housed therein.

In the main body 3, a lower roll 31, a gluing roll 32, and a leveling roll 34, which form a pinch roll for taking in the cloth, are arranged in parallel in the lower part of the cloth passing surface on the glue tub, and A doctor roll 33 and a sizing roll 35 are arranged in contact with the sizing roll. The gluing roll 32 is supported by ball bearings 37a, 37b press-fitted into the frame side plates 30a, 30b, and the lower roll 31, the doctor roll 33, and the leveling roll 34 are directly or through holes formed in the frame side plates 30a, 30b, respectively. The bearing is supported via a solid lubricating ring, and the glue-up roll 35 is directly supported by another bearing plate 40 made of engineering plastic arranged on the bottom surface of the glue tub as shown in FIG.

In the upper cover 6, above the cross passage surface, an upper roll 61 that constitutes the pinch roll for taking in and a drive roll 63 that applies a feeding tension to the cross 7 are arranged in parallel. These bearings are directly or through a solid lubricating ring in the holes formed in the frame side plates 60a and 60b. Further, a presser roll 62 which presses the cross 7 from above and rotates following the cross roll 7 is arranged in parallel between the upper roll 61 and the drive roll 63, and the presser roll 62 is left and right via the presser angle adjusting links 66a and 66b. Is supported by the frame side plates 60a and 60b.

The main body 3 and the upper lid 6 are hinged to each other on the rear side of the frame side plates, and the positions of the respective parts are determined so that the rolls are in the state shown in FIG. 2 when they are closed. In this state, the upper and lower pinch rolls 61 and 31 pinch the cloth 7 therebetween, and the drive roll 63 and the leveling roll 34 come close to each other via the cloth 7.

The rotation of the motor 8 is transmitted to the sizing roll 32 by the gear, and further transmitted to the lower roll 31 and the doctor roll 33 by the gear on the other end side of the sizing roll 32. The leveling roll 34 is driven from the doctor roll 33 via a gear, and the sizing roll 35 is driven from the sizing roll 32 via another gear. Further, with respect to the upper lid 6 side, the drive roll 63 is driven by being connected to the leveling roll 34 and a gear in a closed state thereof, and the other pressing roll 62 and the upper roll 61 are rotated by contact with the cloth 7. It is a freewheel. A rotary encoder 64 such as a photomicrosensor is attached to the upper roll 61 so as to function as a length measuring roll of glued cloth.

In the gluing operation, the upper lid 6 is opened and the tip of the cloth 7 is pulled out from the cross roll 4 and hung down from the rear side of the main body through the space between the upper and lower pinch rolls 61 and 31 to the front side, and then the upper lid 6 is closed. The motor 8 is driven by a predetermined initial amount. The rolls connected by gears are rotated by a drive of the motor 8 at a predetermined peripheral speed ratio, whereby the glue in the trough attached to the gluing roll 32 by the gluing roll 35 is adjusted in advance by the doctor roll 33. The adhesive on the surface of the gluing roll 32 is transferred and applied to the back surface of the cloth 7 that is controlled by an appropriate amount and moves with the rotation of the gluing roll 32 under the pressing effect of the pressing roll 62.

The glued cloth is then pulled out by the drive roll 63 and the leveling roll 34 in a state in which an appropriate tension is applied, and comes out to the front surface of the main body. At this time, the peripheral speed difference of the leveling roll 34 is increased. Gives a leveling effect on the glue surface. When the cloth 7 comes out to the front by the initial amount, stop the motor 8 once and cut the glue non-adhered part at the tip along the cutter guide 36 with a cutter, then input the required cross length from the operation panel 65 and perform the same operation. When the motor 8 is driven, the cloth of the required length glued to the back surface of the entire length is accumulated in a folded state on the cloth receiver (tray) 4 on the front surface. The vibration generated in each roll during this work is effectively absorbed by the frame side plates 30a, 30b, 60a, 60b made of engineering plastic, and a stable gluing work can be performed with a quiet running sound.

[0021]

[Effect of the device]

 As described above, according to the present invention, each roll such as a sizing roll, a doctor roll, a leveling roll, a drive roll, a vertical pinch roll, and a press roll is made of engineering plastic as the left and right bearing plates in the main body. Since it is supported by a pair of frame side plates, most of the rolls can be directly supported by the through holes formed in the frame side plates, and the weight of the main body can be quantified and the number of used parts such as bearing bushes can be reduced. In addition to being able to drastically reduce the number, it is easy to install ball bearings and bearing rings, and the frame side plate as the bearing plate can be easily molded by, for example, reaction injection molding and slight cutting, and it can be installed in a roll. Disassembly and reassembly is extremely easy, and vibrations caused by roll rotation during operation are effectively absorbed by the frame side plates. As a result, large vibrations will not be transmitted to the cover or frame of the gluing machine, so that not only vibration noise during work will be reduced, but also it is possible to prevent meandering and wrinkling of wall coverings and uneven glue. It is what is done.
