Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention can be used in coating machine unwinding units, offset newspaper rotary presses, and other machines that require continuous supply of wound webs (cloth, film, laminated paper, etc.). This invention relates to an automatic coil paper tape tailoring device.

(Prior Art) Conventional automatic coil paper tape making devices (transfer type unwinders) have required up to two or more workers to manually apply tape to the unwind roll.

In the conventional unwinding roll tape application work, it was necessary to sequentially feed (paper splicing) the coiled paper 1 (unrolled paper) as in an unwinding machine of an off-machine coater having a transfer method. In addition, in order to carry out the paper splicing, it was necessary to form the lead portion (FIGS. 6 and 7) in advance so that it could be continued so that it could be carried over to the preceding paper in a suitable manner.

FIG. 3 is a schematic side view of the conventional transfer method 3, FIG. 4 is a view from A in FIG. 3, and FIG. 5 is a schematic diagram of the transfer method 4. Transfer method off-machines 3 and 4 are schematic diagrams, but the only difference is whether the coil paper 1 is spliced upwards or downwards, and there are other major differences. There isn't. In addition, the dashed-dotted line part shown in part B of FIG. 3 is the position where the splice tape applying device 31 of the present invention is installed.

Now, the coiled paper 5 wound by the paper machine is placed on the unwinder device 6 shown in FIG. are sequentially sent through the stopper kicking device 15.

Further, the formation work of the lead portion 2 is performed by using a cylinder 9 to push up the rail flip-up portion 8, which is located in the middle of the rail, and also to prevent the coiled paper 10 from rolling during upstream storage.
Although only one worker is shown in the figure, two to three workers also climbed on top of the rail 7 and used metal underlays, knives, etc. to create the zigzag shape shown in FIG. 6 as an example of the shape. The lead part 2 is made entirely by hand, such as cutting, fixing key points with paper presser tabs 11, and pasting double-sided adhesive tape 12 along the lead ends.

When the old coiled paper 13 reaches a predetermined diameter, it is calculated by a computer, the old coiled paper 13 is lifted upward by the transfer arm 16, and the new coiled paper 14 is sent out by the stopper kicking device 15, and the state shown in FIG. 4 is achieved. become. When the diameter of the old coiled paper 13 becomes smaller, the paster arm 17 moves forward, detects the diameter of the new roll with a phototube and stops, and the unwinder DC motor 47 starts, and the surface speed of the new coiled paper 14 changes to the line speed. Immediately after the lead portion 2 provided on the surface of the new coiled paper has passed, the splice roll 19 is pressed against the new coiled paper 14 side, and after one rotation, the double-sided adhesive tape 1 is
2, and then attach the new coil paper lead to the old coil paper 1.
Immediately after that, the old coil paper side is cut by knife 20, tension control is transferred from the transfer arm to the unwinder stand, and the frame change is completed.

The frame change for transfer method 4 shown in FIG. 5 is roughly the same. The shape of the lead portion 2 is usually optimal depending on the type of coating machine, basis weight, paper width, and running speed. In other words, various efforts have been made to prevent air from being entrained during frame change synchronization, how to prevent the tip of the lead from coming undone, and how to advance the lead part 2 immediately after frame change without getting caught in the mechanical system. Therefore, in order to make it easier to change the frame, the lead portion 2 is formed in a dogleg shape or a mountain shape, as shown in FIGS. able to make.

However, although the work of changing the frame of the unwinding section of the off-machine coater in the conventional equipment is automated, the work of applying tape for the unwinding roll (tailoring work) is difficult to automate, and the challenge is how to automate it. It was hot. Therefore, at present, the process is carried out manually by one or two workers, which has been a major hurdle in automating the entire line, including the coating section and liquid preparation section. Furthermore, since the work is performed near rotating objects, not only is the work dangerous, but the adhesive tape must be applied with an accuracy of 0.5 mm to 1 mm (Fig. 6), which increases worker fatigue. It was.

(Problems to be Solved by the Invention) The present invention attempts to solve the problems that occur due to the conventional automatic tape tailoring work for coil paper being performed manually.

(Means for Solving the Problems) For this reason, the present invention provides a guide plate that detects that a new coil paper is transferred to a splicing tape application device and rises to guide the paper, and a guide plate that is guided by the guide plate. A phototube device detects the unwound paper and stops the rotation of the new coiled paper, and a suction box is provided at the bottom of the guide plate to suck the unwound paper, and the suction box is attached to the suction box to attract the new coiled paper. It has a configuration in which the paper is pulled up and tensed until the phototube device stops operating, and the double-sided adhesive tape is applied by the tape pasting device and then automatically cut by the cutting mechanism to form the lead part, which solves the problem. It is used as a means for point-solving.

(Function) The paper is fed out using the center support method, the paper is adsorbed to the suction box, and then the paper is pulled up a little to make it taut, and the lead portion is accurately formed and cut by controlling a phototube or the like.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. Figs. 1 and 2 show the general configuration of a transfer system, an off-machine coater unwinding roll, and an automatic tape pasting device in an embodiment of the present invention. show.
In the figure, 3 is the transfer system, 6 is the unwinder, 7 is the rail, 13 is the old coil paper, 14
is the new coil paper, 16 is the transfer arm, 18 is
19 is a transfer motor, 19 is a splice roll, and 20 is a knife, which are the same as those in the conventional apparatus, so a detailed explanation thereof will be omitted here. Further, the rolling and feeding mechanisms are also the same as before.

Now, in FIGS. 1 and 2, the new coiled paper 14 from which defective paper has been removed by the rewinding machine, trimmed and stored is rolled on the rail 7 via the wheels 39 by the stopper kicking device. , is loosened by an oil damper 32 at the splice tape application device 31 installed at section B in FIG. Also, spool 4 of new coil paper 14
A clutch 36 actuated by a cylinder 35 is attached to the engine 0.

Further, a phototube detects the diameter of the new coiled paper 14, and the guide plate 38 is raised so that the paper, including the new coiled paper 14 especially in the case of a small diameter, can be guided by the guide plate 38 and lowered. At the bottom of the guide plate 38, a suction box 43 that is longer in the X direction by the width of the new coiled paper 14 + α is installed, and the new coiled paper 14 is moved in the direction of arrow A 41 by an unwinder DC motor 47 via a coupling or the like. When the paper is rotated and fed out, the paper hangs down in front of the suction box 43 and stops when the phototube 44 is cut off, and the paper is brought into close contact with the suction box 43 by suction suction. Then, while suctioning the paper, it is slightly rolled up in the direction of arrow B 42 until the phototube breaks, and the wrinkles of the paper are removed. At that time, if the riding roll 37 is lowered, the surface layer of the new coiled paper 14 will be loosened, so it is raised, and when the paper is pulled up, the suction surface of the suction box 43 must also be parallel to the Y direction 46.

Next, the new coil paper 14 to which the double-sided adhesive tape 12 has been pasted is cut, and in the case of the embodiment shown in FIG. 1, this is done by a CO ₂ laser cutting machine 49. In addition to this, mechanical cutting can also be used. 50 is a sliding table, which can be moved in the X direction 45 by a motor 51.

Further, when the lead portion 2 as shown in FIG. 6 is automatically formed, it passes through a pressing nip of a riding roll 37 coated with silicone rubber so that it can be easily peeled off. At this time, the adhesive side of the label paper is pressed onto the new coil paper 14 to complete the lead end. Next, the cylinder 35 engages the clutch 36.
is removed, and the new coil paper 14 is removed from the kicking device 52.
The rail 7,
It is sent via wheels 39. Note that the waste paper after laser cutting is discharged from the bucket 53. In addition,
The automatic adhesive tape applying device 48 and the CO ₂ laser cutting machine 49 may be structured to move in the x and y directions on a sliding table 50.

Next, the operation of the embodiment configured as described above will be explained. When the new coil paper 14 stored by the unwinder device 6 is transferred to the splicing tape pasting device 31, the clutch 3
6 is installed, the guide plate 38 rises when the phototube is detected and guides the paper, and the unwinder DC motor 47
is rotated in the direction of arrow A 41 to feed out the paper. The fed paper stops when the phototube 44 is cut off, and while being sucked by the suction, the paper passes through the phototube 4.
Roll up the paper a little until the number 4 breaks and tension the paper in the suction box 43.

Next, the double-sided adhesive tape 12 is pasted using the automatic adhesive tape pasting device 48, with a gap 21 of 0.5 to 1 mm.
Cut with a CO ₂ laser cutting machine 49. Note that this cutting may also be done mechanically. In this way, the lead portion is fully automatically formed, and the label paper is passed through the pressing nip of the silicone rubber-coated riding roll 37, and the adhesive side of the label paper is pressed onto the new coil paper 14.

The new coiled paper 14 having the lead portion formed in this way is transferred to the paper feeding section of the unwinder 6, fed to the old coiled paper 13 being fed, and then transferred to the splicing tape pasting device 31 as follows. A new coiled paper 14 is automatically attached, and the operation for forming the lead portion 2 is performed.

(Effects of the Invention) The present invention is configured as described in detail above, and the tape application work is completely automated, which enables labor savings, and accurate repeatability increases the success rate of frame replacement. , it is possible to reduce production costs. Note that if it is controlled by a computer, it will be possible to respond to various tails and specifications by changing inputs or calling. Further, in the present invention, commercially available double-sided adhesive tapes and commercially available tab label paper can also be used.
