Description

Detailed Description of the Invention [Industrial Field of Application] The present invention is applicable to dry, laminating, printing presses, and coaters, as well as to relatively large-sized paper (500μ to 900μ) for reel winding.
This invention relates to a composite film cutting and automatic winding device that cuts the film (about μ) and automatically winds it onto another paper tube.

[Prior art] Conventional dry laminated composite films have been generally used in which thin films are cut with a cutter, and the leading edge of the film hits a glued paper tube and is glued, automatically winding it up and winding it up. ing.

[Problems to be solved by the invention] Thin films of the composite films described above, e.g.
Films of about 0μ can be cut with an oscillating cutter without much difficulty, and the tip of the cut film hits the above-mentioned glued paper tube and is then glued and rolled up, but it is not dry laminated. If the film is a thick composite film, the saw blade-shaped cutter will cut it, so even if it is oscillated, the tip of the blade will bounce off and will not cut into the film, making it impossible to cut it. Furthermore, even if it were possible to cut the film, the film would not fit in with the rollers, so it would continue straight forward, making it impossible to wind it into the paper tube. Therefore, there is a drawback that the winding operation cannot be carried out unless the machine is stopped and the paper tube is pasted to the paper tube so that winding can be done manually.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention has been proposed in order to deal with the problems of the conventional manual method. At the same time, a heater is also used on the oscillating cutter side to heat the cutter, which allows it to bite into the film better and cut the film, and the cut edge is curled. The paper is guided in the direction of the paper tube by a guide plate installed on the cutter side, while the gluing roll applies glue to the paper tube and also acts as a presser roll to assist and hold down the paper, allowing it to be automatically wound and wound. It is intended to streamline work.

[Function] The plastic film fed from the take-up reel a of the first paper feed section A is coated with adhesive while passing between the coating roll 3 and the impression cylinder 4 in the coating section B, and then transferred to the drying section C.
While passing through this drying section, the adhesive is dried and sent to the laminating section, while the reel a1 of the second paper feeding section
The rolled film is sent to the laminating department, and
Together with the film sent from the drying section C, the film is sent between the laminator roll 7 and the pressure roll 8 and bonded together to form a composite film.
It is cooled and sent to the cutting and winding section F.

This cutting and winding section F supports the winding paper tube 43, 43a at two locations with turret arms.

Also, when cutting a composite film wrapped around a paper tube at this turret position and performing automatic paper splicing, first turn on the paper splicing button, move the paper tube 43a supported by the turret to the regular position, and then The upper swing arm 17 is swung down by the cylinder 18 from the chain line position to the solid line position around the axis, and the lower swing arm 34 is similarly swung up around the axis by the action of the cylinder 35. .

At this time, the heater roller 33 and the presser roller 32, which also serves as gluing, arranged on the lower swing arm 34 are each moved into a cylinder 36.
37 is operated and extended, and the silicon roller 15 and holding roller 16 arranged on the upper swinging arm 17 are connected to the cylinder 2.
9. It overhangs due to the action of 30. At this time, the composite film f includes the guide roller holding roller 16, the heater roller 33 and the paper tube 43.
Tension is applied by the silicone roller 15 pressed against the point A and the tension roller 31, the paper is guided by the guide roller 41 provided at the tip of the upper swinging arm 17, and wound onto a paper tube 43 supported by the other end of the turret arm 42.

Further, the composite film f passing through the heater roller 33 is softened by heating by the heater roller 33, and the holding roller 16
The cutter 14 is curled by the silicon roller 15 and placed on the upper swing arm 17 side under tension, so that the blade body 14b touches the heater plate 14c
The cutter 14 equipped with the heated blade 14b is swung by the action of the cylinder 22 and cuts the composite film f.

At this time, the tip of the cut composite film f has become soft and curled, and this tip is held by the silicone roller 1.
5, and is guided toward the paper tube 43a by the arcuate surface 40a of the auxiliary plate 40 provided on the tip side of the cutter 14. At this time, the paper tube 43a is glued by the gluing/pressing roller 32, and the composite film f is pressed and wound around the paper tube 43a.

After cutting, the cutter 14 and silicone roll are turned OFF, the upper swing arm 17 returns to its original position, the lower swing arm 34 is lowered, and the heater roller 33 is turned OFF.
It becomes F and returns to the original state.
