The present invention relates to a method and an apparatus for winding a narrower width by folding several times in a single process in the production process of a synthetic resin film and resin coated paper.

Conventional winding methods of resin film and resin coated paper are used to transport the produced site film to the paper pipe and transport, store or use it as it is, or to cut it as needed and manually push one of the cutting plates in the middle of the resin descent. When folded in four and divided into four, this is done in the same way again, so the folding process is long and it takes a lot of space, and it is done manually, which requires a lot of effort, and when the resin is lowered, it is zigzag on the ground plane. When it is too long, it is necessary to fold it into two or three pieces of suitable length, and to fold it by hand and reduce the volume in one packing unit. And user inconvenience.

The present invention has been studied to improve such closure, and the present invention is to invent an automatic device and a method of automatically cutting off by a machine, which is wound around a branch of a winding machine.

In the present invention, even when the width of the resin film is large or small at an arbitrary width, the desired folding winding is possible by simply changing the standard of the present invention as it is, but the present invention will be described with an example to make it easier to understand. However, the present invention is not limited to this example, and the technical principles and configurations as illustrated above are all within the scope of the present invention.

The following description of the present invention will be described by way of example a tubular resin film (film folded in two layers) having a width of 4 m in diameter of the synthetic resin film.

The present invention provides a corrugated plate (7) in the folder body (1) installed on the descending line of the double-layered film, the tubular fabric resin film extruded by the known method is lowered through the intermediate support roller (14). Joining the two connecting plates, each of which is connected by a hinge (9) as a platelet, seals both ends to form a narrowly spaced film passage, applying pressure to only one or both ends of the corrugated plate and bending them in a zigzag shape. It is characterized by comprising a serrated bent corrugated plate, which is passed through a resin film or a resin coated paper between the bent corrugated plate, and then crimped into desired equal parts, and a wrinkled film installed at a position below 2.5 to 3 m. Can be completely folded by the cutting roller 15, and can be rolled up to the branch pipe in a state of being folded into the desired width and equality, and, if it is rolled up in an appropriate volume, cut and package it. As, it is a simple, automated way by the machine without damaging the product in terms of transport, use, and that will contribute to the reduction of the work force Tuesday.

Thus, the present invention will be described with reference to the drawings.

The folder body 1 of the present invention and each component embedded in the main body may have different specifications according to the diameter of the produced resin film.

Example 1

In the case where the resin film diameter is 4 m, a preferable standard is a rectangle having an upper side and a lower side having a width of about 6 m, a width of about 1 m, and a height of 20 to 30 cm, and both ends thereof are struted up and down driven by air pressure or hydraulic pressure.

The side plate guide groove pipe 4 'into which the both end protrusions 5' are fitted is disposed on the bottom face of the foldable side plate 4 at a length of about 1 m, and is about 2 to 5 cm from the front plate 2 side. Guide groove of about 60cm is arranged horizontally in a straight line.

In some cases, a method of inserting a rebound spring into the pipe to move the drive back and forth may also be used.

In addition, the middle guide groove pipe 5 and the front surface is a pipe or groove pipe in which the guide groove 5 '″ is arranged in a horizontal direction except for about 1m at both ends in the transverse direction.

The corrugated plate 7 between the intermediate guide groove tube 5 and the front plate 2 has a plate length of 50 cm and a plate width of 10 to 20 cm with a plate thickness of 1 to 3 mm (depending on the material). It consists of two sets of refractive plates connected by (9).

This plate is a hard, lightweight material, especially aluminum or stainless steel, and sometimes wood.

In connecting the eight plates so that they are refracted by the hinge, a connecting plate (hereinafter referred to as a front plate) alternately arranged with different hinge bending directions and a plate in which the hinge is arranged to be folded in the opposite direction to the front plate (hereinafter referred to as a front plate) The back plate) is connected to fix the two connecting plates through a sponge so as to have a distance of about 5 to 10 mm, thereby forming a narrow and long space (a quadrangular tunnel) as shown in FIG. (As the resin film passes through and the film passes downward, the crimping and joining plate bends to fold and fold the film.)

At the end of the hinge connection portion 9 'at both ends of the "front plate" (8) and at both ends of the hinge 9 at the "back plate" (8'), the protruding crimping plate projections 6 and the protruding projections 8 are wrinkled. The connecting plate of the holding plate protrudes at right angles in a row on the center line in the transverse direction, and a driving roller 6 " and a driver 8 "

The corrugating plate 7 is placed in parallel between the front plate 2 and the intermediate guide groove tube 5 and is attached to the driving roller 6 attached to the projection 6 protruding from the front plate 8 of the corrugating plate. ") Is driven by being guided by the guide groove 11 of the pipe installed behind the front plate 2 and the guide groove 5 'of the pipe provided in the front of the intermediate guide groove pipe 5, and guide groove pipe The driving holes at both ends of (10) are connected to the air pressure or the pressure transmission hole (13), and the center of the guide groove groove pipe of the front plate (2) is the center of the projections protruding from the front plate (8) of the corrugating plate (7). The projection 6 'is fixed at its tip, and a rebound spring 32 is built in between the driving sections of each of the corrugated plate projections 6, and is opened to the left and right sides at the central point where the central projection is fixed.

On the other hand, the driver 8 '"of the protruding protrusion 8" on the back plate 8' of the corrugating plate is also driven to the left and right by the groove 5 '"of the intermediate guide groove 5.

The creasing plate of the folder of the present invention configured as described above can be configured by the method described above on page 8, 10 or more, and the length of the platelet can also be long or short to an arbitrary length. The folder body can also be manufactured to any length.

The operation of the interceptor of the present invention is explained.

Example 2

In the conventional method, the resin film is injection-molded and the cutting device is disposed on the descending line which descends through the intermediate roller, and then the cutting device is first lowered by pneumatic or hydraulic pressure to a high position (about 5 to 6 m high). The resin film is crimped about the winding width of the folding film roller 15 located about 2.5 to 3 m below through a rectangular square space (tunnel) spaced about 5 to 10 mm, which is the center space of the corrugating plate, to be wound on the winding machine. Be prepared.

At this time, the crimping plate (7) in the cutting machine is the force of the rebound spring (12) sandwiched between the front end drive and the driving hole of the projection (6) protruding in the cutting portion, the back plate and the intermediate guide groove pipe The spring (3 ") repulsion force sandwiched between (5) acts together, and the front plate 8 of the crimping plate is pushed to the left and right from the portion where the central projection 6 'of the center bend end is fixed and creases. The platelets are adjacent to the body front plate 2 to form a straight line.

However, by applying air pressure or hydraulic pressure, the lowering of the presser body about 1m, and at the same time, the pressure transmission port for delivering air pressure or hydraulic pressure installed at both ends of the guide groove pipe 10 installed at the rear of the front face of the cutter ( 13) both end projections of the intermediate guide groove pipe (5) is retracted toward the rear plate (3) along the groove of the side plate guide groove pipe (4 '), where the {pressure transfer hole 13 is one side or Both sides can be operated at the same time.} At the same time, the repulsive force of the reaction spring 12 acting on the driving roller 6 "of the protrusion 6 protruding from the front and rear bending position of the corrugation plate 7 The driving roller (6 ") is pushed toward the center fixed point, and at the same time, the middle guide groove groove (5) is combined with the force pushed toward the back plate (3) of the folding machine, and the intermediate guide is bent as the crimp platelets are deflected. Groove tube (5) is pushed to the rear, wrinkles small When the angle of refraction is sharpened and the folder main body reaches the point of 2.5 to 3 m above the ground which is lowered to about 1 m, as shown in FIG. 3, the corrugating plate 7 is completely serrated and the film passage is zigzag-shaped. It is formed into a space, and the film passing through this passage is cut in a zigzag shape and exits from the corrugated plate 7. At this time, a mark may be attached to one end of the creasing plate 7 to provide a display scale of the driving distance of the mark and the cutting angle thereof.

For example, an 8-inch creasing plate of about 4m length is connected to the hinge at intervals of 50cm in length, so that the resin film escaped from the creasing plate is an 8 width creasing resin film that is bent at about 60 ° at 50cm intervals. This comes out, and this passes through a 90 ° turning roller installed below, which is a cut film of about 50 cm width overlapped with 8 widths, which is then rolled onto the branch pipe inserted in the winder. Thus, when the predetermined amount is wound, it is cut, packaged, and distributed.

The cutting method of the cutting machine of the present invention is an innovative method of winding a wide pipe of a wide resin film or resin coated paper into a small width that is convenient for transportation and storage without manual labor and is convenient for use as an automated process without manual labor. It greatly contributes to the industry.
