Detect ear deviation.

Next, the operation of the above embodiment will be explained.

When the paper roll 6 loaded on the trolley 5 is sent to a fixed position in the device, the pair of arms 8, 8' descend and move left and right to detect the paper core of the paper roll 6 and chuck it with the holding parts 7, 7'. King and hold. Thereafter, the arms 8, 8' rise to lift the web 6, and stop with its surface in contact with the presser roll 30.

When the surface of the web 6 comes into contact with the presser roll 30, a limit switch (not shown) is turned ON and the cylinder 22 is activated.As a result, the advancing/retracting rod 20 equipped with the cutter 25 advances toward the surface of the web 6, and the cutter 25 moves toward the surface of the web 6. It digs into the surface to a specified depth.

This depth of biting naturally varies depending on the diameter of the paper roll 6, but is adjusted by an eccentric bearer (not shown). Also, although the web below the cutter 25 hangs down due to this cut, it is held down by the presser roll 30 and does not slip down.After this, a limit switch (not shown) is turned on.
NL, a drive member and motor 26 (not shown) are driven, and as a result, the cutter 25 is rotated and the web 6 is rotated.
Move from one end to the other and cut into the web. When the cutter 25 reaches the other end, a limit switch (not shown) is turned ON, and the motor 10 is then driven to rotate forward, rotating the rotary wheel 12 and rotating the web 6 clockwise in FIG. 1 at a low speed. When the cut end of the web 6, cut by the cutter 25, reaches a predetermined position a before contacting the presser roll 30, the motor 10 stops.
Stopping of the cut end at a predetermined position a is determined by the rotation angle from the cutter 25 position to the predetermined position fia, for example α1 (α2 ) and stops the motor 10 when the set measurement value is reached. That is, although the rotation angle α, (αa) changes depending on the diameter of the web 6, the rotation angle β, (β2) of the arms 8, 8'
) and preset this in advance. After the motor 10 has stopped, when a predetermined period of time has elapsed using a timer or the like, the motor 10 is driven in the reverse direction.
The web 6 is rotated counterclockwise at low speed. At the same time, air supplied through the air pipe 33 is blown out from the nozzle, and the rotation causes the web at the cut end side of the web 6 to be fed to the workbench 15 side to float, thereby ensuring that the web is placed on the workbench. invite.

The web of the web 6 fed into the workbench 15 is connected to the drive shaft 1.
The nip roll 125 rotated by 27 sequentially
It is fed onto the surface of the workbench, passes through the nip rolls 126, hangs down into the waste paper box 130, and discharges the waste paper cut by the cutter 25 into the box. During the feeding, since the depth of the cut made by the cutter 25 is uncertain, it is necessary to remove any scratches that may occur.

Therefore, 3 to 5 sheets of the web 6 and the length necessary for V-cutting are fed out, and the edge deviation detection member 131 detects whether or not the edge deviation occurs in the web fed out at this time.

The length of the feed is measured by a second detector (not shown) attached to the end of the presser roll 30, and when the necessary amount of good paper without any deviation is fed out, the motor 10 is stopped.

At this time, the web on the workbench 15 is
, 126, the tension is applied and a stable state is maintained.

After the motor 10 is stopped, when a predetermined period of time has elapsed using a timer or the like, the motor 10 is again driven to rotate normally, and the web 6 is rotated clockwise at a low speed, so that the unwound web is rewound.

Along with this rewinding, the cutter motors 50, 50
' starts, the air cylinders 46 and 46' operate, and the movement of the support plates 45 and 45' causes the cutter 48.
48' contacts the web of web 6 that is fed over the groove 56. At the same time, a drive member (not shown) is driven, and the carriage 40.40' moves from the end surface of the web 6 toward the center of the winding width via the ball screw 41.42, and the combination of these two movements causes the carriage 40.40' to move into the groove 56. The cutter 48° 48' moving along begins the cut for forming the V-shaped section into the web of the web 6.

After the units 35 and 35' are activated, the second detector detects the amount of movement of the web of the web 6 being rewound on the workbench 15, and the tape pressing rollers 60, 60 are moved at a controlled timing.
' is brought into contact with the web by air cylinder 62.62',
Adhere the tip of the double-sided tape to the edge of the paper that is being cut into a V-cut. At this time, in order to continue adhering the double-sided tapes 52 and 52' without difficulty, the wheel motors 55 and 55' are started and the feeding of the double-sided tapes is started in synchronization.

The motors 55, 55' are activated just before the V-cut begins the double-sided tape adhesion process, and the tip of the double-sided tape having the length shown in the figure is sent out in advance to a position directly below the tape pressing rollers 60, 60', and is then put on standby. In addition, double-sided tape 52.52'
When loading the tape onto the tape reel 51.
53' and presser rollers 57, 57' to engage them. After biting, the knobs 53a and 53'a
When the wheels 53 and 53' are turned, the tip of the tape is manually pierced. When cutting by hand, the tape is fed in multiple passes so that the leading end of the tape passes through the cutters 48 and 48', and the tape cutters 63 and 63' are operated by operating a manual switch to cut the leading end.

The cutter 48.48' maintains contact with the web, and the cutting operation continues, but the double-sided tape 52.5
Since it is necessary to avoid the brake belt contact area when bonding 2', that operation must be skipped.

The skip operation for adhering the double-sided tape is performed by operating the tape cutter 63, 63' with the air cylinder 66, 66' at the timing of the web movement corresponding to the L dimension of the double-sided tape before the skip position, and removing the double-sided tape. is cut to a predetermined size, and the wheel motor 55,
55' and wheels 53 and 53' are stopped to stop feeding the double-sided tape. Tape cutter 63, 63'
The leading part of the tape cut by the tape presser roller 6
0 and 60' and movement of the carts 40 and 40' toward the center of the winding width, the adhesive is bonded to the skip position. The pressing rollers 60, 60' remain in the attached state when the cutters 48, 48' perform the cutting operation, and are removed after the double-sided tape has reached the length of the tape.

On the other hand, the operation of adhering the double-sided tape again after the completion of skipping is performed by using the tape cutter 63,
63' has been reset, the wheels 53 and 53' are rotated by the motors 55 and 55', and the double-sided tape of length L is fed out to below the presser rollers 60 and 60', and preparations are made to start re-adhesion. do. Then, upon receiving a re-adhesion start signal, the presser rollers 60, 60' perform the adhesion operation, and the motors 55, 55' are activated at the same time.

As the above operation continues, a plurality of double-sided tapes 52, 52' are attached at predetermined intervals to the upper surface of the edge of the V-shaped portion of the paper roll 6 at the same time as the V-cutting operation.

When the units 35, 35' operate a reset button (not shown), the carts 40, 40' move to the standby position on both sides of the workbench 15, cutters 48, 48' and wheels 53, 53'.
Then, the tape pressing rollers 60, 60' return to their original positions, such as the positions where they left the web.

When V-cutting and skipping pasting of double-sided tape are completed by units 35 and 35'.

Operation of unit 36 begins.

First, while the suction pad 93 of the trolley 73 in the standby position shown by the chain line in FIG. 5 starts suction, the air cylinder 87
The tab paper 98 is lowered by the hopper 99 and comes into contact with the top surface of the uppermost tab paper 98 placed on the lid 103 in the hopper 99 and is attracted thereto. The suction pad 93 that has suctioned the tab paper is raised and returned to its original position.

Thereafter, the motor 76 is driven, and the carriage 73 moves to the right in FIG. 5 via the screw, and stops when the suction pad 93 is located above the suction pad 115 for peeling off the base paper of the tab paper 98. Next, the suction pad 115 starts suction, is raised by the air cylinder 116, contacts the base paper surface of the tab paper 98, and pinches the base paper between the lower diagonal piece 121 of the frame 120. The tab paper 98 is lowered by the air cylinder 116, and the base paper of the tab paper 98, which has been sucked by the suction pad 115, is thereby peeled off from the tab paper itself.

The cart 73 equipped with the suction pad 93 that suctions the tab paper 98 with the base paper peeled off moves to the right as the motor 76 further rotates in the normal direction, and stops at the position shown by the solid line. . Then, the operator waits until the top of the V-shaped portion comes to a position corresponding to the cutter, and when the top comes to the predetermined position, the motor 10 is stopped and the rotation of the web 6 is stopped.

When the rotation of the web 6 stops, the cylinder 85 is actuated and the cutter 83 comes into contact with the web on the workbench 15. When the motor 76 moves the cart further to the right, the cutter 83 makes the cut indicated by the chain line in FIG. As it moves horizontally while contacting the web at position 135, the top of the V-shaped portion of the web is cut. This state is shown in FIG. When the cutting of the top part is completed, the nip roll 126 rotates clockwise in FIG. 1 and discharges the excess paper after cutting. Further, after the cutting, when the suction pad 93 is located above the cutting position 135, the tab paper suctioned by the suction pad 93 is moved between the cut top part and the starting end side of the web 6 by the air cylinder 87. It is pressed and adhered to the web.

The cutting and tab paper adhesion positions are also determined by measuring the amount of movement of the web using a second detector.

When the reset button is operated in the same way as in the units 35 and 35', the cart 73 returns to the standby position on the left in FIG. 5, and the cutter 8.
3 and the position where the suction pad 93 is away from the workbench 15, etc.
Each returns to its original position.

The operation control of the members in each unit and the operation control between the units is performed by a control member made of a known electric component.

Since the present invention has the above-described configuration, the V for forming the V-shaped portion is performed before the web is attached to the three-prong rotating device.
Preparation work before paper splicing, such as cutting, applying double-sided tape, and pasting paper tabs, has been automated, and this work can be done quickly and efficiently while unwinding the paper web on the workbench. It has excellent effects.
