[0001]
[Industrial application fields]
The present invention relates to an automatic gluing machine. More particularly, the present invention relates to an automatic wallpaper pasting machine capable of guiding the leading edge of wallpaper discharged by applying glue and folding it while matching the paste surfaces.
[0002]
[Prior art]
A schematic configuration of a conventional automatic wallpaper pasting machine is as follows. As shown in FIG. 1, the automatic gluing machine includes a measuring roller (1), a feeding roller (2), a high tension roller (3), a doctor roller (4), a gluing roller (5), a gluing roller ( 6) The presser roller (7) and the tear roller (8) are arranged, and the wallpaper (A) to be glued is sandwiched between two rubber rollers, the measuring roller (1) and the feeding roller (2). Then, it is fed into the main body of the gluing machine.
[0003]
The measuring roller (1) is rotatably supported at both ends between the left and right frames, and since this roller is pressed against the wallpaper surface by a spring, it is unidirectional according to the feeding of the wallpaper (A). Rotate to. The outer diameter of the roller is set to a constant value, and the rotation amount of the roller is detected by a slit plate and a photomicrosensor that equally divides the circumference. The length of the wallpaper (A) is measured, and this length information is always displayed on the operation unit, and the worker is working while watching the situation. The high tension roller (3) and presser roller (7) work to make the glue uniform and smoothly transport the wallpaper (A). The glue is placed in the glue box (9) that is detachable at the bottom of the body. Stored.
[0004]
The glue in the glue box (9) is transferred to the glue roller (5) by the glue upper roller (6). By adjusting the distance between the doctor roller (4) and the glue roller (5), the thickness of the glue attached to the outer periphery of the glue roller (5) is adjusted. A layer of glue with controlled thickness comes in contact with the wallpaper (A), transfers the glue to the back of the wallpaper (A), leveles the glue transferred by the pear roller (8), and transfers the wallpaper from the front of the gluing machine. (A) is discharged.
[0005]
The wallpaper (A) discharged from the front is stacked while being folded so that the glued faces face each other. As a method for assisting folding, a paper receiving plate (11) has been widely used conventionally. When the machine reaches the preset length, the machine automatically stops. After the machine stops, the operator runs the blade of the cutter knife along the cutter guide (10) to cut the wallpaper (A). Obtain the desired length of glued wallpaper (A). The cut wallpaper (A) is folded and cured in a state where both ends are butted.
[0006]
The work of stacking the discharged wallpaper (A) in a folded manner with the glued surfaces facing each other will be described in detail. After the glue starts, the tip of the wallpaper (A) is slightly discharged. Grab the left edge of the wallpaper (A) with your left hand and the right edge of the wallpaper (A) with your right hand. Move it to the back side of the paper receiving plate (11) by hand and place it so that the tip of the wallpaper (A) protrudes slightly from the paper receiving plate and hangs down. At this time, place the paper backing plate (11) so that the front side (surface without glue) of the wallpaper (A) is in contact with it, and then place it so that the back sides (surface with glue) are aligned. ing.
[0007]
There is a proposal called a folding guide to be combined with the paper receiving plate (11) as an apparatus for performing the operation of guiding the leading edge of the wallpaper (A), which has been performed manually by the operator, to the paper receiving plate (11) without manual intervention. Has been made.
[0008]
As shown in FIG. 1 (a), FIG. 1 (b) and FIG. 7 (a) to FIG. 7 (d), before the start of gluing, the plate-shaped guide piece (33) is transferred to the wallpaper (A). The tip of the surface of the wallpaper (A) on which the glue is attached is pasted on the guide piece (33) (FIG. 7 (a)). The guide piece (33) and the wallpaper (A) are lowered by the weight of the wallpaper (A). (FIG. 7 (b)) During this lowering, the guide thread (33) is guided to the back side of the paper receiving plate (11) by the guide thread A (34), so that the wallpaper (A) is transferred to the paper receiving plate ( 11) to the back side. (FIG. 7 (c)) The wallpaper (A) whose leading end is guided to the back side of the paper receiving plate (11), when the discharge is continued, the drooped portion abuts against the slope of the paper receiving plate (11). The paper receiving plate (11) is placed with its surface facing down on the lower slope. If the discharge continues from this state, the hanging part of the wallpaper (A) will deviate from the vertical line, so the force to return to the normal direction works, and as a result, the way of placing the wallpaper (A) turns naturally, It is placed on the back side of the paper receiving plate (11) in the direction in which the glue surfaces meet. Even when the paper receiving plate (11) is folded and extended, the wallpaper (A) is turned and folded again by the same action. (FIG. 7 (d)) Before starting the next gluing, pull the other guide thread B (35) to return the guide piece (33) to its original position and repeat the same process again. It is.
[0009]
[Prior art issues]
Performing the operation of guiding the leading edge of the wallpaper (A) to the paper receiving plate (11) by hand is a burdensome work because it is carried out with a middle waist or even when a chair is used. There has been proposed a device for guiding the leading edge of the wallpaper (A) to the paper receiving plate (11) without human intervention. The work of sticking the surface to which the mark is attached to the guide piece (33) has to be performed, which is troublesome. Also, after discharging the wallpaper (A), it takes time to remove it, and at the same time it removes the glue from the tip of the wallpaper (A) after it has been removed. The part where the piece of wallpaper (33) is to be pasted becomes dirty and must be cleaned. In addition, it takes time and effort to return the guide piece (33) to the original position by pulling the guide yarn B (35) before the discharge is finished and the pasting of the next wallpaper (A) is started.
[0010]
[Means for solving the problems]
In an automatic wallpaper pasting machine that applies glue to the back of the wallpaper, when the glue is applied and discharged, it touches the vicinity of the front edge of the wallpaper surface where no glue is applied, and between the left and right legs of the glueing machine in inducing wallpaper tip to the back side of the picture receiving member, the wallpaper surface side have a wallpaper guide means for guiding in contact with the wallpaper receiving member, the wallpaper guide means, depending on the gluing speed of wallpaper, wallpaper It starts after a predetermined time or a predetermined length of time from the start of gluing, guides the leading edge of the wallpaper at a speed according to the gluing speed, and the wallpaper surface side is placed in a predetermined position in contact with the wallpaper receiving member An automatic wallpaper pasting machine characterized by guiding to (Claim 1)

[0015]
DETAILED DESCRIPTION OF THE INVENTION
As an example of the present invention, FIG. 2 (a), FIG. 2 (b), and FIG. 8 (a) to FIG. Indicates. A guide arm (14) is used as a mechanism for guiding the front end of the wallpaper (A), and this guide arm (14) has one right arm (14) on the inner side near the left leg (12) of the gluing machine body. 13 is provided on the inner side near 13), the fulcrums of the left and right guide arms (14) are connected by the arm fulcrum shaft (19), and the tips are connected by the wallpaper guide rod (16). The wallpaper guide bar (16) is preferably subjected to a treatment such as rubber lining that increases the friction of the surface so that the wallpaper does not easily come off when the tip of the wallpaper (A) comes into contact. Hereinafter, the guide arm (14) with the wallpaper guide rod (16) is referred to as a guide arm (14).
[0016]
This guide arm (14) is installed inside the left and right legs of the gluing machine body, and is wider than the width of the wallpaper (A). The guide arm (14) is driven by a motor (17) and moves so as to draw an arc around the arm fulcrum shaft (19). The moving direction is determined by the rotation direction of the motor (17), the guide arm (14) is extended from the position shown in FIG. 8 (a) to the position shown in FIG. 8 (d), and the leading edge of the wallpaper (A) is placed on the paper receiving plate. Guide to the back of (11). When the guide arm (14) is in the position of FIG. 8 (a), the origin position of the guide arm (14) is, and when it is in the position of FIG. 8 (d), the guide completion position of the guide arm (14). It is. FIGS. 2A and 2B show a state where the guide arm 14 is stopped at the origin position.
[0017]
An arm origin stopper (18) may be provided at the origin position so that the guide arm (14) accurately stops at the origin position. The guide arm (14) is driven by the motor (17), and the driving force of the output shaft of the motor (17) is transmitted to the arm fulcrum shaft (19) by the arm drive gear (21). During this time, the torque limiter is transmitted. (20) is installed.
[0018]
Even if the motor (17) rotates without stopping even after the guide arm (14) returns to the origin position and contacts the arm origin stopper (18), the torque limiter (20) ) And the guide arm (14) are intended not to be damaged, and the position is detected whether the guide arm (14) has returned to the origin position during the return movement to the origin position. Instead, the control is performed by setting a slightly longer time based on the data obtained in advance based on the relationship between the driving time and the driving speed.
[0019]
The installation of the torque limiter (20) also serves to apply only a force that does not cause injury even if the operator's feet or hands are sandwiched between the moving guide arm (14).
[0020]
Needless to say, in order to detect the origin position of the guide arm (14) and the guide completion position, a limit switch, an optical sensor, etc. are provided to determine whether the guide arm (14) has returned to the origin position. The position may be detected and controlled.
[0021]
FIG. 6 shows a control block of the wallpaper leading edge guide mechanism. In order to measure the length of the glued wallpaper (A), the output of the encoder (FG) that generates a number of pulses corresponding to the movement distance of the wallpaper provided in the past is taken into the counter 1 (22). The counter 1 (22) is cleared to zero at the start of gluing, counts the discharge length of the glued wallpaper (A), and when reaching a predetermined activation count value (26), guide arm drive control is performed. The circuit (24) drives the motor (17) so that the guide arm (14) moves.
[0022]
By this command, the guide arm drive control circuit (24) rotates the motor (17) at a predetermined speed in the extending direction of the guide arm (14) for a predetermined time and stops it.
[0023]
FIG. 8 (a) to FIG. 8 (d) show the operation of the guide arm (14) moving so as to draw this arc. As shown in FIG. 8A, when the gluing operation is started, the wallpaper (A) with gluing is discharged at a gluing speed set by the operator. The glue surface of the wallpaper (A) is the surface in contact with the gluing roller (5), and the other surface is the surface to which no glue is applied. After the start of gluing, the guide arm (14) starts the feeding operation when the tip of the wallpaper (A) slightly passes the guide rod (15) of the guide arm (14). (Fig. 8 (b))
[0024]
The time from the start of gluing to the activation of the guide arm (14) needs to be changed according to the gluing speed. In this embodiment, the encoder (FG) pulse provided in the past for measuring the length of the glued wallpaper (A) is taken into the counter 1 (22), counted, and a predetermined guide arm drive is performed. Control is performed so that the motor is activated when the activation start count value (26) stored in the motor control circuit is reached. The time from the start of gluing to the start of the guide arm (14) is shorter if the gluing speed is faster and longer if it is slower. I can't guide you in contact. In the present embodiment, the length of the discharged wallpaper (A) is measured, and data is taken in advance so that the guide arm (14) can be driven in the feeding direction when the length becomes appropriate. The start count value (26) is stored in the guide arm drive motor control circuit. Further, this length is used as a time from the start of the gluing corresponding to the gluing speed to the start of the guide arm (14), and data is taken in advance, and the driving time timer 1 (25) is provided inside the guide arm drive motor control circuit. It may be stored and used as a substitute for the activation count value (26).
[0025]
Instead of using the activation start count value (26), an optical sensor may be disposed below the arm feeding origin position to detect that the leading edge of the wallpaper (A) has reached a reasonable position.
[0026]
As shown in FIG. 8B, the vicinity of the front end of the wallpaper (A) is brought into contact with the guide rod (15) of the guide arm (14) and guided to the back side. If the feeding speed is too fast at this time, the leading edge of the wallpaper (A) will be disengaged from the guide rod (15), and if it is too slow, the glue surfaces will be joined together in an unintended place during the guidance. The guide arm (14) must be driven at a different speed. In this embodiment, the guide arm (14) is driven in the arm feeding direction at a speed corresponding to a speed command issued from the gluing operation control circuit to a circuit for controlling the driving of the roller group for gluing.
[0027]
As shown in FIG. 8C, when the leading edge of the wallpaper (A) is guided to the guidance completion position (near the position slightly behind the back end of the paper receiving plate), the guide arm (14) is stopped. The time during which the guide arm (14) is moving is controlled by a driving time timer 2 (27) determined in advance according to the moving speed of the guide arm (14).
[0028]
The product of the moving speed of the guide arm (14) and the moving time of the guide arm (14) can be taken as the length of the wallpaper (A) discharged from the start-up to the stop of the guide arm (14). Therefore, when another counter 2 (23) is provided, the length of the discharged wallpaper (A) is counted, and the predetermined stop count value (28) of the guide arm (14) is reached. The driving time timer 2 (27) may be substituted by stopping the operation.
[0029]
As shown in FIG. 8D, after the guide arm (14) is stopped, the discharged wallpaper (A) is accumulated in a state where the glue surfaces are well overlapped on the paper receiving plate (11). Is done. The wallpaper (A) guided at the tip to the back side of the paper receiving plate (11), when the discharge is continued, the hanging portion abuts on the paper receiving plate (11), and the slope of the paper receiving plate (11) It is placed with the surface facing down. When the wall is discharged from this state, the hanging part of the wallpaper (A) is removed from the vertical line, so the force to return to the normal direction works, and as a result, the wallpaper (A) turns naturally and the glue surfaces are joined together. In the direction, it comes to be placed on the back side of the paper receiving plate (11). Even when the paper receiving plate (11) is folded and extended, the wallpaper (A) is turned and folded again by the same action.
[0030]
In order to perform the next gluing, the gluing start start switch provided in the operation unit of the conventional gluing machine is pressed to return the guide arm (14) from the guide completion position to the home position. Immediately before entering the operation, it is performed by moving the drive time timer 2 (27) at a predetermined time and speed in the return direction.
[0031]
In FIG. 6, the portion described as counter 1 (22), counter 2 (23), or drive time timer 1 (25), or drive time timer 2 (27) is composed of either hardware or software. You may do it.
[0032]
Further, in this embodiment, the speed for guiding the wallpaper is obtained from the speed command issued from the gluing operation control circuit to the circuit for controlling the driving of the roller group for gluing, but the pulse frequency of the encoder (FG) is The speed may be controlled in accordance with the pulse frequency of the encoder (FG), that is, the driving speed is increased when the driving speed is increased and is decreased when the driving speed is decreased.
[0033]
3 (a), 3 (b) and 9 (a) to 9 (d) as another embodiment, the leading edge of the wallpaper (A) is moved to the paper receiving plate (11) by a linearly moving guide rod. An example of guiding to the back side of the vehicle will be shown. This is because a timing pulley (29) is provided inside the tip of the left and right guide arms (14), and a timing belt (30) is hung between the timing pulley (29) and the arm fulcrum shaft (19). The guide rod (15) is linearly fixed by fixing the guide rod (15) to the timing belt (30), attaching the torque limiter (20) to the output shaft of the motor (17) and rotating the arm fulcrum shaft (19). To move the wallpaper (A) to the back side of the paper receiving plate (11).
[0034]
For the control, the method described in the block diagram of FIG. 6 is used as it is. As shown in FIG. 9 (a), after the start of gluing, the length of the glued wallpaper (A) is taken into the counter 1 (22), and when the predetermined activation count value (26) is reached, guidance is provided. The bar (15) starts the feeding operation, and as shown in FIG. 9 (b), the guide bar (15) comes into contact with the vicinity of the front end of the wallpaper (A) and moves at a speed proportional to the pasting speed. To guide the wallpaper (A), and stop at the guidance completion position after the time set by the driving time timer 2 (27) as shown in FIG. 9C, and the wallpaper (A) as shown in FIG. 9D. Is folded and overlapped on the paper receiving plate (11).
[0035]
As an example of moving the guide rod (15) linearly, an example is shown in which the guide rod (15) is moved horizontally. However, the origin position may be raised and moved from diagonally upward to diagonally downward. In this case, care must be taken not to interfere with the installation of the cut tape that has been used conventionally.
[0036]
FIGS. 4 (a), 4 (b) and FIGS. 10 (a) to 10 (d) show an embodiment in which the upper half of the paper receiving plate (11) performs the same function as the guide arm (14). This is formed by the arm supporting shaft (19), the guide arm (14), and the guide rod (15) in FIGS. The rectangular space portion is formed of a plate to form a guide plate (32), and this portion serves as both the guide arm (14) and the upper half of the paper receiving plate (11).
[0037]
For the control, the method described in the block diagram of FIG. 6 is used as it is. As shown in FIG. 10 (a), after the start of gluing, the length of the glued wallpaper (A) is taken into the counter 1 (22), and when the predetermined activation count value (26) is reached, the guidance is performed. The plate (32) starts to start, and as shown in FIG. 10 (b), the front end of the guide plate (32) comes into contact with the vicinity of the front end of the wallpaper (A) and moves at a speed proportional to the glueing speed. Thus, the wallpaper (A) is guided, and after the time set by the driving time timer 2 (27), as shown in FIG. 10 (c), it stops at the guidance completion position, and the wallpaper (A) as shown in FIG. 10 (d). ) Folds over the paper receiving plate lower portion (31) and the guide plate (32).
[0038]

[0039]
For the control, the method described in the block diagram of FIG. 6 is used as it is. As shown in FIG. 11A, after the start of gluing, the length of the glued wallpaper (A) is taken into the counter 1 (22), and when the predetermined activation count value (26) is reached, the guide bar (15) starts the feeding operation, and as shown in FIG. 11 (b), the guide rod (15) comes into contact with the vicinity of the front end of the wallpaper (A) and moves at a speed proportional to the pasting speed. The wallpaper (A) is guided and stopped at the guidance completion position after the time set by the drive time timer 2 (27) as shown in FIG. 11 (c), and the wallpaper (A) is displayed as shown in FIG. 11 (d). It is folded and overlapped on the paper receiving plate (11).
[0040]
【The invention's effect】
As explained in detail above, after the start of the gluing, the guide is in contact with the vicinity of the front end of the wallpaper (A) on the surface side to which no gluing has adhered, There is no need to guide the leading edge to the paper receiving plate (11), and the operator needs to attach the adhesive-coated surface of the leading edge of the wallpaper (A) to the guide piece (33). Can be eliminated.
[0041]
Further, when the next wallpaper (A) is glued to the guide arm (14) and the guide bar (15), the glue start start switch provided in the operation unit of the conventional glue machine is pressed. Just before entering the gluing operation, the guide piece B is pulled by pulling the guide yarn B (35) in order to wait at the origin position by moving the drive time timer 2 (27) in the return direction at a predetermined time and speed. There is no need to return (33) to the original position.
[0042]
Since the guide rod (15) is in contact with the surface of the wallpaper (A) where the glue is not attached, the guide rod (15) is guided without contact with the glue on the guide rod (15). In the same way, there is no need to clean the part where the wallpaper is pasted. As described above, all the problems of the prior art are solved.
