DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic wallpaper gluing machine for gluing wallpaper to an indoor wall when pasting the wallpaper onto an indoor wall.

[0002]

2. Description of the Related Art FIG. 13 shows the internal structure of a conventional automatic wallpaper gluing machine. In the figure, reference numeral 1 denotes a gluing machine main body, and a roll-shaped material wallpaper 2 (cloth) set on a leg (not shown) is inserted into the gluing machine main body 1 from the rear side (left side in FIG. 13) and inspected. Length roller 3 (rubber roller)
Then, the adhesive is transferred to the back side by the gluing roller 5, the glue is transferred to the back side, and the glue surface is leveled by the flat roller 6 (the right side in FIG. 13). A sizing path is configured to be discharged from the outlet of the stencil. Also, the gluing route includes
A doctor roller 7 for adjusting the thickness of the glue film of the glue roller 5 is provided, and a high tension roller 8 for giving an appropriate tension to the wallpaper 2 to make the glue uniform and accurate. A pressing roller 9 is provided.

[0003] The roller group consisting of the measuring roller 3, the feed roller 4, the gluing roller 5, the flat roller 6, the doctor roller 7, the high tension roller 8 and the pressing roller 9 is composed of a freely rotating measuring roller 3 and high tension. Except for the roller 8, it is driven by a power transmission mechanism composed of gears. Therefore, gears are provided at the roller shaft ends of the feed roller 4, the gluing roller 5, the flat roller 6, the doctor roller 7, and the pressing roller 9, respectively. And
These gears are distributed to both ends in the longitudinal direction of the gluing machine main body 1 as shown in FIGS. 14A and 14B, and a gear 10 for driving the feed roller 4 and a gear 11 for driving the gluing roller 5 are provided. A gear 12 for driving the doctor roller 7 is provided at the left end when viewed from the front of each roller shaft, and is provided at the left end of the sizing machine main body 1 on the side where a drive source (not shown) such as a motor is provided. A gear 13 for driving the flat roller 6 and a gear 14 for driving the holding roller 9 are provided at the right end of each roller shaft, and are arranged at the right end of the gluing machine main body 1 as shown in FIG. As shown in (a), power is transmitted from a gear 15 connected to a drive source to a gear 11 for driving the gluing roller 5, and a gear 12 for driving the doctor roller 7 and a gear 10 for driving the delivery roller 4.
A gear train is formed at the left end of the main body so that the gears 10, 11, 12, 15 mesh with each other so that the power is sequentially transmitted to the main body.
(B), the power is transmitted from the gear 16 provided at the right end of the gluing roller 5 to the gear 14 of the pressing roller 9, and further to the gear 13 of the flat roller 6. A gear example in which the gears 13, 14, 16 mesh with each other is formed at the right end of the main body.

As shown in FIG. 14B, two idler gears 17 are provided in the gear train at the left end of the sizing machine main body 1 so that power is sequentially transmitted from the gear 16 of the sizing roller 5. , 18 are arranged. These idler gear 1
Reference numerals 7 and 18 denote gears for transmitting power to a slitter (wall paper cutting machine) described later.

The measuring roller 3 is rotatably supported at both ends, is urged toward the feed roller 4 by a spring (not shown), and is pressed against the wallpaper 2 sandwiched between the roller and the feed roller 4. Rotate in one direction according to the feed of 2. The measuring roller 3 is for detecting the length of the sent wallpaper 2, and for example, a slit plate provided with a slit at a position obtained by equally dividing the circumference is attached to the shaft end. Then, the rotation of the slit plate is detected by the photo micro sensor. The photomicrosensor generates a pulse in accordance with the rotation of the slit plate, that is, the rotation of the measuring roller 3, and counts the pulses to measure the amount of rotation of the measuring roller 3. Then, the moving distance of the roller peripheral surface, that is, the length of the fed wallpaper 2 is detected from the measured rotation amount and the outer diameter of the measuring roller 3 which is known in advance. The dimension information detected in this way is always displayed on the operation panel. The operator can work while judging the situation by looking at the displayed information. When the detected value reaches a preset value, the machine stops automatically.

The feed roller 4 is driven by the gear 10 so as to feed the wallpaper 2 between the measuring roller 3 and the glue roller 5 as described above.
Since it is necessary to feed the wallpaper 2 without gluing it, it is arranged on the entrance side.

The gluing roller 5 transfers the glue to the back surface of the wallpaper as described above. The sent wallpaper 2 comes into contact with the outer peripheral surface of the gluing roller 5 at a predetermined winding angle.
Then, the glue roller 5 rotates at a peripheral speed higher than the feed roller 4 while causing a slip with the wallpaper 2 having a low feed speed, thereby rubbing the back surface of the wallpaper 2 with the glue. At that time, in order to obtain the necessary gluing function, the wallpaper 2
It is necessary to set the winding angle and the roll diameter so that the roller contacts the glue roller 5 in the circumferential direction with a contact length equal to or greater than a predetermined length. In addition, the sizing roller 5 is a sizing machine main body 1.
And a transmission shaft of a power transmission mechanism separately arranged at both ends of the power transmission mechanism, and a shaft diameter for obtaining a required torsional rigidity is required. In order to satisfy such requirements, the sizing roller 5 generally has a roll diameter of 80 mm or more. For example, when the roll diameter is 86 mm, the winding angle is set to, for example, 63 °.

[0008] The wallpaper 2 fed by the feed roller 4 needs to be guided to the outlet side under an appropriate tension. Therefore, it is preferable that the peripheral speed of each roller driven by the gear while being in contact with the wallpaper 2 be increased in the order of the feed roller 4, the glue roller 5, the pressing roller 9, and the flat roller 6, but in the actual machine, The peripheral speed ratio of the gluing roller 5, the pressing roller 9, and the flat roller 6 is variously configured.

The automatic wallpaper sizing machine is used by transporting it to a work site by car or the like, and the smaller and lighter the weight, the less labor required for the transportation. However, the mechanical size is limited in the longitudinal direction by a space for accommodating a mechanism for supporting the shaft of the roller group, a gear for driving the roller group, and the like, in addition to the width of the wallpaper. Further, in the machine width direction, interference between gears is prevented under constraints such as a required diameter of each roller and a diameter of the gear (diameter of a pitch circle) for obtaining a required peripheral speed for each roller. Need
Further, since it is necessary to arrange a gear for transmitting power to the slitter, the gear train is arranged at both ends of the gluing machine main body 1 as shown in FIG. They are holding back. The gears 10, 11, 12, 13, 14, 15, 16, 17, 18 for driving the roller group and driving the slitter without increasing the size in the machine width direction.
If you try to place all of them on one side (left side of the main body), FIG.
As shown in FIG. 5, the gears interfere with each other.

The gluing machine main body 1 is divided into an upper frame 1a and a lower frame 1b, and the lower frame 1b is connected to the upper frame 1a on the front side so that it can be opened and closed up and down from the rear side. It is configured to be fixed by 19. And, on the upper part of the lower frame 1b,
A feed roller 4, a glue roller 5, a flat roller 6, and a doctor roller 7 of the above roller group are provided, and a measuring roller 3, a high tension roller 8, and a pressing roller 9 are provided on the upper frame 1a. In the lower frame 1b, a lower stay 20 for supporting the wallpaper 2 is installed at an entrance position where the wallpaper 2 is sent, and a glue cut 21 is installed at an exit position where the wallpaper 2 is discharged.

A glue box 22 is provided below the roller group on the lower frame 1b. On the inside of the glue box 22, an over-glue roller 23 is provided with a fixed (usually about 1 mm) gap between the glue roller 5 and the glue roller 5. The glue roller 23 receives power from the glue roller 5 by a gear (not shown), and rotates in a direction opposite to the glue roller 5.

The glue is stored in a glue box 22, lifted by the rotation of the glue upper roller 23, and transferred to the glue roller 5. When the glue roller 23 rotates, the surrounding glue is pulled to the roller surface by its viscosity and is guided to the glue roller 5. Then, the induced glue is transferred to the gluing roller 5 and is transferred from the gluing roller 5 to the back surface of the wallpaper 2. At this time, the doctor roller 7 adjusts the thickness of the glue film adhered to the outer periphery of the gluing roller 5, thereby adjusting the glue thickness of the wallpaper 2. To supply glue, pull out the glue box 22,
Glue is poured in using a ladle or the like from the opening formed above.

Normally, the wallpaper 2 is pulled out of a state of being wound in a roll shape (the above-mentioned roll-shaped raw material) with the top and bottom in the longitudinal direction and is supplied to the sizing machine main body 1. 2, on one side in the short side direction, there is a portion of only backing paper called an ear which is inevitably generated in the manufacturing process, and since there is no cover with a pattern printed on this ear portion, at the time of actual construction, It is necessary to cut out these ears prior to gluing. Therefore, a wallpaper cutting machine called a slitter is mounted on the sizing machine main body 1.

As shown in FIGS. 16 and 17, the slitter 30 is removably mounted on the main body of the gluing machine. A pair of rotating blades, a lower blade 31 and an upper blade 32, are mounted inside a slitter frame 30a. The lower blade 31 and the upper blade 32 are oppositely rotated in a state where the lower blade 31 is pressed against the upper blade 32 with a constant force by a compression coil spring (not shown), and the blade edges are installed so as to face each other and the blade edges overlap in the axial direction, The upper blades 32 are configured to be inclined so that they come into contact with each other at one point on the upstream side in the wallpaper entering direction.

On the slitter frame 30a, a hook 33 is provided on the upper side facing the side connected to the gluing machine main body 1, and a fixing tool such as an elastic hook clip 34 or a snap lock is provided on the lower side. Provided. The upper hook 33 is hooked on the lower stay 20 provided on the gluing machine main body 1, thereby supporting the weight of the slitter 30. The elastic hook holding piece 34 is made of a spring material as shown in Japanese Patent Application Laid-Open No. 9-150084, has a slit and a groove, and has a pin body 35 provided on the gluing machine main body 1. It is deformed by being pushed in and can be mounted with one touch, and is restrained by the pin body 35 so as to suppress the vertical movement of the slitter 30 during operation.

The lower blade 31 and the upper blade 32 of the slitter 30 are rotated in the same direction as the paper 2 passes in FIG.
Rotate in opposite directions as indicated by arrows. The rotation direction of the lower blade 31 is counterclockwise (CCW) when viewed from the right side of the machine,
The rotation direction of the upper blade 32 is clockwise (CW). Also, the wallpaper 2 passing through the slitter 30 becomes a natural flow with few bends, and the lower blade is placed on the passing line of the wallpaper 2 of the natural flow.
As shown in FIG. 18, the upper blade 32 is arranged on the side farther from the gluing machine body 1 so that the contact point 36 between the 31 and the upper blade 32 is located, and the lower blade 31 is closer to the gluing machine body 1. Located on the side. On the other hand, in a case where the lower blade 31 and the upper blade 32 are arranged vertically and there is no difference in the distance from the gluing machine main body 1, FIG.
As shown in (2), the passing line of the wallpaper 2 becomes unnatural with many bends.

[0017] As shown in FIG.
The lower blade 31 and the upper blade 32 are provided with gears 37 and 38 on their respective shafts, and the gears 37 and 38 are directly meshed with each other so that the lower blade 31 and the upper blade 32 rotate in opposite directions. In order to receive power transmission from the sizing machine main body 1, one idler gear 39 is installed on the slitter 30 at a position close to the connection surface with the sizing machine main body 1, and the idler gear 39 is connected to the lower blade 31. Gear 37. The idler gear 39 of the slitter 30 is a slitter frame of the idler gears 17 and 18 arranged on the right end gear train so that power is transmitted sequentially from the gear 16 of the gluing roller 5.
It meshes with the idler gear 18 which is closer to the connection surface with 30a, and these two idler gears 17 on the sizing machine main body 1 side.
The power transmission mechanism for driving the lower blade 31 and the upper blade 32 of the slitter 30 is configured by the idler gear 39 on the slitter 30 side.

The direction of rotation of each gear of the power transmission mechanism for driving the slitter 30 is as shown by an arrow in FIG. 20A, and the gear 37 of the lower blade 31 is counterclockwise (CCW) and the upper blade is
The gear 38 of the 32 is clockwise (CW), and the idler gear 39 of the slitter 30 that meshes with the gear 37 of the lower blade 31 is the clockwise (CW) of the gluing machine body 1 that meshes with the idler gear 39 of the slitter 30. Idler gear 18 closer to the connection surface
Is counterclockwise (CCW), and the other idler gear 17 that meshes with the gear 16 of the sizing roller 5 on the sizing machine main body 1 side is clockwise (CW). The idler gear 18 on the glued main body 1 and the idler gear 39 on the slitter 30 which are in mesh with each other with the connection surface interposed therebetween have their rotation directions upward at the contact positions of the gears.

As described above, the lower blade 31 and the upper blade 32 of the slitter 30 rotate under a load when the lower blade 31 is pressed against the upper blade 32 by the spring. And
The load due to the spring is constant, but in actuality, the gear 3 of the slitter 30
The load on 7, 38, 39 constantly fluctuates, and when the load suddenly increases due to the fluctuation, the gears 37, 38,
39 may be in a state close to fixed for a moment, at that time, the idler gear 39 on the slitter 30 side and the gluing machine body 1
The upward force acting on the contact position with the idler gear 18 on the side increases as shown in FIG. 20B, and the upward force acts in a direction to lift the slitter 30. A conventional automatic wallpaper gluing machine uses a hook piece 33 to move the slitter 30 up and down due to such upward force.
And the elastic hook clamping piece 34 is trying to suppress it.

[0020]

Since the automatic wallpaper gluing machine is used by transporting it to a work site by car or the like, it is required to be as small and lightweight as possible. In addition to the width of the wallpaper, there are restrictions on the space for accommodating the mechanism for supporting the shafts of the roller group and the gears for driving the roller group, so it is difficult to achieve further compactness. On the other hand, with regard to the dimension in the width direction, the gear train of the power transmission mechanism for driving the roller group should be arranged at both ends of the gluing machine body so that the gears do not interfere with each other as described above, thereby achieving compactness. Is conventionally performed. However, there is no other way to further reduce the size of the machine in the machine width direction, except for drastically changing the configuration of the existing machine, such as reviewing the roller arrangement and changing the roller support structure. In such a case, the conventional technology usually cannot maintain performance comparable to existing machines.

Further, when the power transmission mechanism is disposed at both ends as described above, design restrictions are reduced, and the gear train can be disposed in a space having a limited cross-sectional area in the width direction. Spaces for disposing gears at both ends of the main body frame are required, so that restrictions on compactness are increased in the machine longitudinal direction.

Further, the roller group is composed of a roller installed on the lower frame of the glued body and a roller installed on the upper frame, and the gears are also divided into the lower frame side and the upper frame side. There are gears that mesh with the frame, and there are also gears that protrude from the upper surface of the lower frame due to the large number of teeth and large diameter, such as the gears of the glue roller. Therefore, it is necessary to provide an opening in the upper part of the space for accommodating the gear train in the lower frame, and to protrude a part of the gear therefrom.
Since water or the like intrudes from the opening at the time of machine cleaning, there are many restrictions on installing electric components inside the lower frame. In the past, instead of installing electric parts on the lower frame, a method of collectively installing electric parts in a separate operation box has been adopted, which is a major factor in increasing the size of the machine. I was

Further, as described above, the conventional automatic wallpaper sizing machine moves the contact position between the idler gear on the slitter side and the idler gear on the main body of the sizing machine due to the fluctuation of the load applied to the blade of the slitter. The upward force acts, and the upward force may cause the slitter to repeat subtle vertical vibrations, and such vibrations may cause extremely inconvenient conditions such as waving and fluffing of the cut surface of the wallpaper. Will threaten the basics of cutting performance. Therefore, as described above, in the conventional automatic wallpaper sizing machine, the vertical movement of the slitter due to the application of such an upward force is intended to be suppressed by the engagement of the hook pieces and the elastic hook holding pieces. However, the upward force to lift the slitter is not lost, but the load fluctuation that occurs continuously causes backlash on the elastic hook clipping piece, and the slitter may start to vibrate up and down eventually .

Therefore, it is an object to realize further compactness while maintaining the performance of the automatic wallpaper sizing machine. In addition, the upward force applied to the slitter is eliminated, and the deterioration of construction quality due to the vertical vibration of the slitter is reduced. The challenge is to prevent

[0025]

According to a first aspect of the present invention, there is provided an automatic wallpaper sizing machine which is detachably mounted on a sizing machine body and is driven by power transmitted from a driving source of the sizing machine body via a gear. In the automatic wallpaper gluing machine provided with a slitter for cutting the wallpaper, the rotating direction of the gear on the gluing machine body side and the gear on the slitter side, which mesh with each other, are configured to be downward at the contact positions of the gears. Features.
In this case, since the rotating directions of the gears of the gluing machine main body and the slitter side that mesh with each other are both downward at the contact position, the upward force applied to the slitter is eliminated, the vertical vibration of the slitter is eliminated, and the cutting performance of the slitter is eliminated. And the construction quality is improved. Further, the configuration in which the rotation directions of the gears on the gluing machine main body side and the slitter side are both downward at the contact position as described above is one of the gears that drive a pair of rotary blades of the slitter, the connection surface with the gluing machine main body Can be realized by directly meshing the gear whose rotation direction is downward on the side close to the gear of the gluing machine main body side, in which case, the gear for driving the slitter on the gluing machine main body side is It may be one idler gear that meshes with the gear of the delivery roller near the inlet side where the slitter is mounted, and therefore, the number of idler gears installed on the sizing machine body is one less than the conventional device,
As a result, the restrictions on the design of the gear train of the power transmission mechanism that drives the roller group are reduced, the space for accommodating the gear train can be reduced, and the widthwise dimension of the gluing machine main body can be reduced.
In addition, the slitter itself can be formed compact because the idler gear is not required.

In the above-mentioned automatic wallpaper gluing machine, the slitter is hooked on the gluing machine main body by the hook and hooked on the upper part, and the slitter is glued by the elastic hook holding piece. It is good to be constituted so that it may be locked to a main part, so that a slitter can be attached by one-touch and up-and-down vibration can be prevented more certainly.

In the above automatic wallpaper gluing machine, a slitter is provided on a pair of rotary blades disposed opposite to each other and on a rotary shaft of each rotary blade, and the rotary blades are rotated in opposite directions. Having a pair of gears meshed to make
It is preferable that one of the pair of gears is configured to mesh with the gear on the side of the sizing machine main body. In this case, of the gears driving the pair of rotary blades of the slitter, the side closer to the connection surface with the main body of the sizing machine. By directly meshing the gear whose rotation direction is downward with the gear on the gluing machine body side, the rotation direction of the gear on the gluing machine body side and the gear on the slitter side are both downward at the contact position of those gears. So that

Further, in the slitter of the automatic wallpaper gluing machine, the gear meshing with the gear on the side of the gluing machine main body is glued more than the connection surface between the gluing machine main body frame and the slitter frame. It is preferable to be configured to protrude toward the machine body frame side. The gear on the gluing machine main body side that meshes with the gear on the slitter side rotates during the machine operation regardless of the presence or absence of the slitter. Therefore, by adopting a configuration in which the gear on the gluing machine main body side is not made to protrude from the main body frame and the gear on the slitter side is made to protrude, safety when the slitter is not connected is increased.

According to a fifth aspect of the present invention, in the automatic wallpaper sizing machine, a power transmission mechanism for transmitting power from a driving source to a roller group of the sizing machine main body is integrated at one end in the longitudinal direction of the main body frame. And By consolidating the power transmission mechanism at one end in the longitudinal direction of the main body frame in this manner, the length of the frame in the longitudinal direction can be reduced as compared with the case where the power transmission mechanism is installed on both sides of the main body frame. In addition, devices other than the power transmission mechanism can be installed in the empty space at the opposite end, and even in that case, it is possible to reduce the space required compared to installing the power transmission mechanism. The size in the longitudinal direction can be reduced. Regarding the power transmission mechanism to be integrated at one end in the longitudinal direction of the main body frame, the gears should not interfere with each other under the constraints of the diameter of each roller of the roller group and the diameter of the gear (diameter of the pitch circle). It is necessary to arrange all the gears. In this case, for example, a slitter for cutting the wallpaper connected to the main body of the sizing machine, a gear group constituting a power transmission mechanism to the roller group as in claim 8 , The power is transmitted via a single idler gear, thereby reducing the number of idler gears for driving the slitter to be installed in the gluing machine main body as compared with the related art, thereby reducing the design of the gear train of the power transmission mechanism. , The space for accommodating the gear train can be reduced, and the increase in the width dimension of the gluing machine main body can be suppressed. Also, among the rollers, the sizing roller and its gears particularly take up space, and the sizing roller needs a required roll diameter to obtain a required sizing function. When the power transmission mechanism is installed at both ends, the glue roller usually also serves as the transmission shaft, so it is necessary to have a shaft diameter to obtain the required torsional rigidity. In the case of consolidation at one end in the longitudinal direction, there is no need to provide a roller that plays the role of a power transmission shaft, so there is no need to determine the torsional rigidity of the glue roller or other rollers as the power transmission shaft. Regarding the sizing function of the roller, for example, the peripheral speed of the sizing roller is set to be larger than the peripheral speed of the sending roller for sending out the wallpaper by a predetermined value or more, so that the diameter of the Also as required glue application performance is obtained by the urging roller, thus, the diameter of the glue application roller is reduced, preferably as claimed in claim 9, wherein 80
mm, the diameter of the gear can be reduced accordingly, the entire gear train can be compactly arranged, and an increase in the width dimension of the gluing machine can be suppressed.

Further, when the power transmission mechanism is integrated at one end in the longitudinal direction of the body frame,
As described, it is preferable to install the control system electrical components in the internal space at the opposite end of the main body frame. The roller group is usually installed over the lower frame and the upper frame of the glued body, in which case the gears are also divided into the lower frame side and the upper frame side, and the gears projecting upward from the lower frame In addition, since the gear of the glued roller having a large number of teeth and having a large diameter usually projects on the upper surface of the lower frame, an opening for projecting a part of the gear is required at the upper part of the lower frame, If the power transmission mechanism is concentrated on one side in the longitudinal direction of the main body frame, it is not necessary to provide an opening in the lower frame on the opposite side, and it can be a sealed structure, so even if electric parts are installed in that part, it can be used during machine washing. It can be protected from water. By storing the control system electric components in the main body frame, it is not necessary to provide a separate large operation box as in the conventional case, and the entire machine can be reduced in size. A controller for operating the gluing machine can be detachably attached to the upper center of the machine body.

An automatic wallpaper sizing machine according to a tenth aspect is characterized in that the gear group for driving the rollers of the body of the sizing machine uses less than two gear modules. Conventionally, the gear for driving the roller group of the gluing machine is usually the module 2. This module 2 is a module that can maintain the gear strength with an appropriate tooth width (less than 10 mm) when a resin gear is used for weight reduction. In order to reduce the distance between the rollers in order to reduce the size of the gluing machine, the number of gear teeth is reduced if the peripheral speed ratio of the rollers is not changed. In this case, it becomes an undercut, making it difficult to manufacture. For this reason, a module 2 having a number of teeth of about 13T to 17T is often used in the conventional gluing machine. This module 2 has 13T ~ 1 teeth
Even if the number of teeth is reduced from about 7T to 11T, which is the production limit, the scale can be reduced by only about 15%.
Therefore, as described above, the gear group that drives the roller group uses gears with less than two gear modules, thereby enabling a large scale-down of the gear train and downsizing of the entire machine. The decrease in strength due to the number of gear modules being less than 2 can be compensated for by adopting a high-strength and lightweight material such as a glass fiber-filled Duracon as the material of the gear.

An automatic wallpaper sizing machine according to claim 11, wherein the diameter of the sizing roller in the roller group of the sizing machine body is 80 m.
m, the peripheral speed of the sizing roller is set to be greater than the peripheral speed of the sending roller that sends out the wallpaper to the sizing roller, and the peripheral speed ratio is set to 1.2 or more. The sizing roller must have a required roll diameter to obtain the required sizing function, and when a power transmission mechanism is installed separately at both ends of the sizing machine main body, the sizing roller also doubles as the transmission shaft. Therefore, a shaft diameter for obtaining a required torsional rigidity is required. Conventionally, a roll having a roll diameter of 80 mm or more has been generally used mainly from the viewpoint of the sizing function. However, if the peripheral speed of the sizing roller is set to be at least 1.2 times higher than the peripheral speed of the feeding roller for sending out the wallpaper, the required sizing performance can be obtained even with the sizing roller having a diameter of less than 80 mm. And by reducing the diameter of the gluing roller in this way, the diameter of the gear also decreases, so the entire gear train is arranged compactly,
An increase in the width dimension of the gluing machine can be suppressed.

Then, the rotation of the slit plate is detected by the photo micro sensor. The photomicrosensor generates a pulse in accordance with the rotation of the slit plate, that is, the rotation of the measuring roller 3, and counts the pulses to measure the amount of rotation of the measuring roller 3. Then, the moving distance of the roller peripheral surface, that is, the length of the fed wallpaper 2 is detected from the measured rotation amount and the outer diameter of the measuring roller 3 which is known in advance. The dimensional information detected in this way is always displayed on the display unit of the controller 44, and the operator works while checking the displayed information to determine the situation. When the detected value reaches a preset value, the machine stops automatically.

The pasting roller 5 has a roll diameter of, for example, 68
mm, which is thinner than a conventional general roll diameter (80 mm or more). The wrapping angle of the wallpaper 2 around the sizing roller 5 is set to, for example, 72 °, which is larger than the conventional wrapping angle of, for example, 63 °, and the length of wrapping of the wallpaper around the sizing roller 5 is 42.7 mm. It has become.

The gluing roller 5 is rotated at a higher peripheral speed than the feed roller 4 so as to rub the back surface of the wallpaper 2 with the glue. In this case, it is 1.33 times, and even if the roller diameter is changed, if the setting is 1.2 times or more,
It has been confirmed that gluing can be performed with almost no problem. Further, each roller driven by the gear while being in contact with the wallpaper 2 guides the wallpaper 2 fed by the feed roller 4 to the outlet side while giving an appropriate tension. The configuration is such that the number of the attachment rollers 5, the holding rollers 9, and the flat roller 6 increases in this order. In the above case, it is desirable that the wrapping length of the wallpaper is 30 mm or more regardless of the diameter of the gluing roller 5.

(approximately m). The glue roller 23 receives power from the glue roller 5 by a gear (not shown), and rotates in a direction opposite to the glue roller 5.

The glue is stored in the glue box 22, lifted by the rotation of the glue upper roller 23, and transferred to the glue roller 5. When the glue roller 23 rotates, the surrounding glue is pulled to the roller surface by its viscosity and is guided to the glue roller 5. Then, the induced glue is transferred to the gluing roller 5 and is transferred from the gluing roller 5 to the back surface of the wallpaper 2. At this time, the doctor roller 7 adjusts the thickness of the glue film adhered to the outer periphery of the gluing roller 5, thereby adjusting the glue thickness of the wallpaper 2.

In this automatic wallpaper sizing machine, in the power transmission mechanism to the slitter 30, the rotation direction of the gear 17 on the sizing machine main body 1 side and the gear 37 on the slitter 30 side that mesh with each other are both downward at the contact position. Since no upward force for lifting the slitter 30 is generated, it is possible to suppress the vertical vibration caused by the load fluctuation when the slitter 30 is operated.
Therefore, the cutting performance of the slitter is improved, and the construction quality is improved.

Further, the gear for driving the slitter provided on the side of the gluing machine main body 1 may be provided with only one idler gear 17 which meshes with the gear 10 of the feed roller 4, so that the gear train can be simplified and the gluing can be performed. The widthwise dimension of the machine body 1 can be reduced.
In addition, the slitter itself can be formed compact because the idler gear is not required.

Also, the power transmission mechanism is integrated at one end in the longitudinal direction of the main body frame, and the other end is used as a closed space 48, and electric parts are installed in that portion.
Electric parts can be prevented from being exposed to water or the like at the time of machine washing, and there is no need to provide a separate large operation box, so that the size of the entire machine can be reduced. In addition, since the operation unit is detachably installed on the upper part of the gluing machine main body 1 as a compact controller 44, it is easy to remove and bring only the controller 44 when leaving the work site for a long time.

The sizing roller 5 of this automatic wallpaper sizing machine has a roll diameter of, for example, 68 mm as described above and is thinner than the conventional one, but the wrapping angle is increased as described above.
For example, by setting the peripheral speed of the gluing roller 5 to 72 ° and a peripheral speed of the feeding roller 4 for sending out the wallpaper 2 by a predetermined value or more, required gluing performance can be maintained. By reducing the diameter of the gluing roller 5 in this way, the diameter of the gear 11 is also reduced, the gear train is made compact, and the dimension in the machine width direction is reduced.

Also, the gears of the gear group for driving the roller group can be reduced from the conventional one having two gear modules to the one having less than two modules, and thereby a large scale of the gear train can be achieved. Down is possible,
The size of the entire machine can be reduced. Gear module 2
The decrease in strength due to less than the above can be compensated for by adopting a high-strength and lightweight material such as a glass fiber-filled Duracon for the material of the gear.
