Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention includes dry laminating, each printing machine and coaters, and is relatively thick for reel winding (about 500 µ to 900 µ).
The present invention relates to a device for cutting and automatically winding a composite film, which is obtained by cutting a film and automatically winding the film around another paper tube.

[Prior Art] Conventionally, a dry laminated composite film is generally used, which is a thin film cut with a cutter so that the leading end of the film hits a glued paper tube and is automatically wound and wound up. ing.

[Problems to be Solved by the Invention] A thin film of the composite film described above, for example, 20 to 50 μm.
It can be cut with an oscillating cutter without difficulty, and the cut film hits the glued paper tube at its tip and is adhered as it is for winding, but it is dry laminated. When the composite film becomes thick, it is cut with a saw-toothed cutter, so even if it is rocked and cut, the sharp edge of the blade body will not be able to cut into the film and cannot be cut. Even if the film could be cut, the film would not go straight to the roller and would continue straight ahead, and could not be wound into the paper tube. Therefore, there is a drawback that the winding operation cannot be performed unless the machine is stopped and the paper core is attached and wound so that the winding can be performed manually.

[Means for Solving the Problems] In view of the above circumstances, the present invention has been proposed in order to address the problems caused by the conventional manual work, that is, a film obtained by drying an adhesive, and Before the cutting, a thick composite film that is dry-laminated with the film to be supplied is softened by passing it through a heater roller, and the composite film is made to fit into a curl shape.Furthermore, a heater is also used on the saw blade-shaped cutter side for cutting. , The cutter body is heated to cut the composite film well and curled, and the cut end is guided by the guide plate provided on the cutter body in the direction of the paper tube to guide the composite film. This is to rationalize the work by gluing the paper core and forming a presser roll to assist the take-up and press-up so that the paper can be automatically taken up and taken up.

[Operation] An adhesive is applied to the plastic film supplied from the take-up reel a of the first paper feed section A while passing between the coating roll 3 and the impression cylinder 4 in the coating section B, and this film is applied to the drying section C. While being sent, the adhesive is dried while passing through the drying section C and sent to the laminating section E. On the other hand, the film wound on the reel a ₁ of the second sheet feeding section D is sent to the laminating section E and is sent together with the film sent from the drying section C between the laminator roll 7 and the pressure bonding roll 8. The composite film is laminated to form a composite film, and the composite film is cooled by the cooling roll 10 and sent to the cutting and winding section F.

The cutting and winding section F has winding paper tubes 43 and 43a supported at two positions of the turret arm, and the composite film wound around the paper tube 43 of the turret is cut by a cutter to perform automatic paper splicing. To do this, first turn on the paper splice button and move the paper tube 43a supported by the turret to the fixed position, and then move the upper swing arm 1
While swinging 7 around the axis O ₁ by the cylinder 18 from the chain line position to the solid line position toward the paper tube 43a, the lower swing arm 34 similarly moves the paper around the axis O ₂ by the action of the cylinder 35. Swing up toward the tube 43a.

At this time, the heater roller 33 arranged on the lower swing arm 34 and the pressing roller 32 also serving as glue are extended by the cylinders 36 and 38 via the operating arms 37 and 39, respectively, and the silicon arranged on the upper swing arm 17. The roller 15 and the holding roller 16 are extended by the action of the cylinders 29, 30 via the operating arms 27, 28. At this time, the composite film f is guided by the guide roller holding roller 16,
Silicon roller 15 pressed against heater roller 33 and paper tube 43a
A tension roller 31 applies tension to the upper swing arm 17, and the upper swing arm 17 is guided by a guide roller 41 provided at the tip of the upper swing arm 17 and wound around a paper tube 43 supported by the other side of the turret arm 42.

Further, the composite film f passing through the heater roller 33 is softened by the heating of the heater roller 33, and is fitted into the curl shape by the holding roller 16 and the silicon roller 15, and is arranged on the upper swing arm 17 side while being tensioned. In the cutter 14, the blade body 14b is heated by the heater plate 14c, and the cutter 14 having the heated saw blade body 14b swings by the operation of the cylinder 22 via the curved arm 20 to cut the composite film f.

At this time, the tip end of the composite film f cut at this time is softened and fits in a curl shape.
Auxiliary plate provided on the tip side of the cutter 14
The arcuate surface 40a of 40 guides the paper tube 43a. The paper tube 43a is glued by the gluing and pressing roller 32, and the composite film f is pressed and wound around the paper tube 43a.

After cutting, the cutter 14 and the silicon roll are turned off, the upper swing arm 17 is returned to its original position, the lower swing arm 34 is lowered, and the heater roller 33 is turned off and returned to the original position.
