DEVICE FOR MAKING INCISION LINE OF PACKAGING FILM}

The present invention relates to a device for forming an incision line of a packaging film, and more particularly, to an apparatus for forming an incision line of a packaging film that can easily and inexpensively form an incision formed for easy opening of a packaging pack.

Recently, the packaging film laminated with other materials such as synthetic resin film and aluminum film is lightweight, has excellent airtightness, high strength, easy handling, and can be formed simply by heat-sealing without the need for adhesives, so that food, medicine, Small items, such as liquids, powders, pastes, solids, and many other types and shapes of goods are packed in a packing pack.

Such a packing pack has a merit that the material has a sealing, and has a problem that is difficult to tear because it has resistance against tearing, and for this purpose, a conventional edge end of the packing pack 100 is shown in FIG. 1. If notches 110 are formed in the chambers, and the notches 110 are tensioned as the cutting openings, the notches 110 can be opened only by the force of a finger.

However, since the part cut through the notch 110 is not always guided to a desired part, and there is a problem of propagating in an arbitrary direction, the incision line 120 is formed long in the longitudinal direction around the notch 110 in recent years. By easily cutting the packaging pack 100 through the notch 110.

On the other hand, the packaging film that is the material of the packaging pack 100 has a laminated structure suitable for the characteristics of the product accommodated therein during manufacture of the packaging pack 100.

That is, when there is no fear that the packaged product will be deteriorated, a packaging film laminated only with the synthetic resin films 111 and 111 'may be used as shown in FIG. 2A, but the received product may be exposed to direct sunlight such as sunlight. When exposed and deteriorated, laminated film including a metal film such as aluminum film 112 between synthetic resin films 111 and 111 ′ as shown in FIG. 2B to block direct sunlight such as sunlight. The packaging pack 100 is manufactured using the cutout 120 by cutting a portion of the laminated film by using a laser irradiated from a laser device configured separately in a state in which the packaging pack 100 is manufactured. Forming.

However, conventionally, a lamination film composed of only synthetic resin films 111 and 111 ′ in a manner of forming an incision line 120 in the packaging pack 100 using a laser device can be smoothly cut, but an aluminum film ( In the case of the laminate film 112), since the strength of the laser cannot be transmitted due to the low intensity, it is necessary to adjust the strength, which makes the work very inconvenient, and the manufacturing cost of the packaging pack is increased because the laser device is very expensive. There is a flaw that rises.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the present invention is to cut the packaging film by the cutting means in the lamination process of the packaging film and then laminated and bonded to the corresponding portion of the packaging pack The present invention provides a device for forming an incision line of a packaging film that allows an incision line to be easily formed.

Another object of the present invention is to form a cut line in the laminated film using a cutting means that is simply configured without having a laser device as in the prior art packaging that can reduce the manufacturing cost when manufacturing a sealed pack An apparatus for forming an incision line of a film is provided.

The present invention is a first winding roll wound the first film corresponding to the inner surface of the packaging pack; A second winding roll on which a second film corresponding to an outer surface of the packaging pack is wound; Cutting means installed at a periphery of the second winding roll in a direction perpendicular to a supply direction of the second film to cut an end of the supplied second film; And adhesive means for adhering the cut second film and the uncut first film into one laminated film.

As described above, according to the apparatus for forming an incision line of the packaging film according to the present invention, the incision is made while directly contacting the cutter, which is a cutting means, in the lamination process of the packaging film, so that a smooth incision is possible regardless of materials such as synthetic resin and aluminum. Of course, it provides an advantage that the failure rate in the process of forming the incision is reduced.

In addition, there is an advantage in that the manufacturing cost of the packaging pack can be reduced because the incision can be easily formed on the packaging film by a simple configuration without using expensive laser equipment as in the prior art.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings such that those skilled in the art may easily implement the present invention.
