And winding to be discarded, but a separate winding for removing the edge film, not the main winding shaft, and the winding method is an arm method, so that a defect is not generated during the winding of the edge film. It is about.

As known in the prior art for the slitting reel there is a Korean Patent No. 353139. This is a technology filed by the applicant since April 6, 2000 patent application.

This will be described with reference to the accompanying drawings.

1 is a schematic view showing the slitting winding machine of the prior art.

The slit winding machine 100 is largely wound on the unwinder 110 formed on one side of the film fabric (F) is run through a plurality of rollers, and is subdivided at a predetermined interval through the cutter 120, The apparatus is configured to wind the cut film on the first and second winding shafts 130a and 130b horizontally moved according to the winding amount by running the roller again.

To explain this in detail, the film fabric F as shown in FIG. 2 supplied from the unwinder 110 is guided to the winding part induction roller 111 and is installed on one side of the winding part induction roller 111. Control) to the detection roller 112.

In addition, the LFC detection roller 112 detects a margin portion of the film fabric F by the LFC detection sensor 112a installed at an upper portion thereof, and interlocks the hydraulic or motor actuator (not shown) to allow the left and right flow of the margin. After correction by the tension detection roller 113 is configured to run immediately without flow.

The film fabric (F) is released from the unwinder 110, the expander roller for correcting that the contraction in the width direction by the tension during the driving after the tension is set by the detection roller 113 for detecting the tension while driving It passes through the 114 and through the induction roller 115 and the like enclosing a pair of cutting rollers (116, 116).

The film fabric (F) is subdivided into a predetermined size through a cutting machine 120 located above the cutting rollers (116, 116) and cut alternately with the upper transfer roller (118a) half alternately It is wound around the first winding shaft 130a installed horizontally through the upper contact roller 117a, and the rest is wound around the second winding shaft 130b through the lower feed roller 118b and the lower contact roller 117b. It is configured to lose.

As shown in FIG. 3, the first and second winding shafts 130a and 130b (see FIG. 4) to which the films Fa and Fb divided and cut by the cutter 120 are wound are slitter ( The first and second guides 100a and 100b formed horizontally on the other side of the substrate 100 are moved horizontally.

That is, the first winding shaft 130a is installed on the fixing bracket 150a fixed to the guide member 160a which is reciprocated to the guide bar 140a provided on the upper side and the lower side of the first guide 100a.

In addition, the second winding shaft 130b is installed on the fixing bracket 150b fixed to the guide member 160b reciprocated in the guide bar 140b installed at the upper side and the lower side of the second guide 100a.

The fixing brackets 150a and 150b to which the first and second winding shafts 130a and 130b are fixed are respectively fixed to the bottoms of the first and second guides 100a and 100b by the cylinders 170a. It is fixed to the rod of 170b and configured to be advanced by the operation of the cylinders 170a and 170b.

That is, after the film Fa (Fb), which is divided into the first and second winding shafts 130a and 130a as shown in FIG. 4, is moved to one side while being wound to cross, the films Fa and Fb ) Is wound to a certain diameter, the operator separates the cut and wound film (Fa) (Fb) from the first and second winding shaft (130a, 130b), the cylinder (170a) (170b) By operating the first and second winding shaft (130a, 130b) is to advance (home position).

In the slitting winding 100 having such a configuration and operation, look at the film fabric (F) as shown in FIG.

The film fabric (F) is a wide width portion of about 5-20mm on both sides of the fabric is processed without a metal deposition. This is a kind of margin inevitably generated during the metal deposition process of the film fabric (F).

Therefore, in the case of the slitting rewinder 100, the process includes removing the unwinding portion (fa, fb) of the film fabric (F) at the time of winding.

Referring to Figure 4, the first winding shaft (130a) and the second winding shaft (130b), each of the films (Fa) (Fb) cut into pieces are wound around each other at a predetermined interval.

In particular, when looking at one end of the first winding axis (130a) and one end of the second winding axis (130b), the film that is not cut portion (fa) and the portion (fb) at the edge of the film fabric (F) is cut off ( It can be seen that Ffa, Ffb) is wound.

Such edge films Ffa and Ffb are always generated portions of the slitting winding machine 100 and may be disposed of after disposal.

In this case, although the edge film Ffa and Ffb are wound around one end of each of the first and second winding shafts 130a and 130b, an electric motor is usually attached to only the edge film Ffa and Ffb. A separate dedicated winding machine or a predetermined blower was installed to suck and store the edge films Ffa and Ffb in a container.

Both of these methods were not efficient due to additional costs, space charging, noise-producing work, etc., so that the first winding shaft 130a and the second winding shaft 130b as in the prior art were wound on one end. Technology was devised.

However, such a technique also led to problems.

That is, when the films Ffa and Ffb are wound, the film Ffa and Ffb may have a deposited portion and a non-deposited portion fa and fb. This results in an imbalance in tension as the winding amount increases. This is caused by the difference in thickness due to the difference in the thermal history of the metal (thin film) and the non-deposited portion, the separation from the winding shafts (130a, 130b) of high speed rotation or winding failure occurred.

Therefore, this separation or winding failure causes problems in manufacturing other normal product films (Fa, Fb). To prevent this, it is necessary to drive at a low speed or to put a paper or extra film between the edge films where the winding tension is loose. It will cause work hassle.

The present invention was devised to solve the above problems, and the object of the present invention is to cut and wind unnecessary portions of both edges of the film fabric when cutting and winding the film fabric of a wide width so as to be discarded, but not the main winding shaft. The present invention provides a slitting winding machine for thin film, in which a winding unit for edge film removal is newly established and its winding method is an arm method, so that no defect occurs when the edge film is wound.
