Laminator structure

TECHNICAL FIELD The present invention relates to a laminator, and in more detail, a normal film laminating operation using a cold film or a hot film and a thin-flex film laminating using a thin-flex film. The invention relates to a laminator device which makes the work workable in one laminator and in which the path of the coating object to be discharged is configured differently.

In general, the laminator is to cover the upper and / or lower surface of the coated object, such as large live prints, large posters, color copies, etc. supplied through the feed panel, and to pass through the wide upper and lower heating rollers It is a coating apparatus which makes a film integral with the upper and lower surfaces of a to-be-coated object.

Conventional laminators perform functions such as hot film laminating, in which a coating layer is coated on upper and lower surfaces of a coating object, and cold film laminating, in which a coating layer is coated only on an upper surface of a coating.

Here, the hot film laminating refers to a coating operation in which a process of applying heat and pressure to the film to be integrated with an object is performed. And, cold film laminating refers to the laminating work that can be applied to only the pressure on the film so that the object and the film are integrated.

Therefore, in the case of hot film laminating, the laminating operation is performed by applying heat and pressure to the roller, but in the case of cold film laminating, the laminating operation is possible even if only the pressure is applied to the roller.

This is due to the characteristics of the film, because the cold film can be performed at room temperature, unlike the hot film. However, both the hot film laminating and cold film laminating have a common point that separation of the coating layer and the release paper layer of the film occurs before coating.

Information on the laminator in which the above operation is performed is described in the Republic of Korea Utility Model '2000-0017518', registered Utility Model '20 -0290887 'and the like.

However, in the case of the cold film or hot film as described above, after the coating process is performed, a process of cutting the coated film using a cutter is required. In addition, the cutting operation is performed manually by the operator.

In order to solve the above problems, a thin flex film has appeared, and the thin flex film (thin-flex film) is a kind of film for single-side coating, and the film is divided into a release paper layer and a coating layer, and a coating process. There is no need to cut the film after this is done. In other words, after the coating layer is coated on the object, the release paper layer is separated by the separator and wound on the rewinder. And, since the coating layer is integrally bonded to the coating object and separated from the release paper layer, no separate cutting work is necessary. And, in the case of the thin-plex film laminating, the separation of the release paper layer is distinguished from the cold film or hot film laminating in that it occurs after the coating is performed.

Meanwhile, due to the characteristics of the film, the position of the rewinder in which the film roll and the release paper layer are wound depends on the time point at which the release paper layer and the coating layer are separated. In other words, in the case of cold film or hot film laminating, the film roll is located at the rear of the rewinder, but in the case of thin flex film laminating, the film roll is located at the front of the rewinder.

However, in the conventional laminator, the cold film or hot film laminator and the thin flex film laminator exist separately, or a separate thin flex film roll holder must be mounted on the cold film or hot film laminator.

Therefore, there is a drawback that the work process for mounting a separate thin-flex film roll holder is increased, and the manufacturing cost for mounting the holder is increased.

In addition, as described above, the position where the coating object was discharged was the same without being divided into the thin flex film laminating operation and the normal laminating operation. Therefore, the coating object must pass through the cutter even in the thin flex film laminating operation, and the coating object passes through the separator even in the normal laminating operation.

The present invention has been proposed to solve the above problems, the thin-film laminating and normal film laminating operation to be performed in one laminator device, so that the position of the outlet to discharge the coating object is formed separately It is an object to provide a laminator device.

In detail, an object of the present invention is to provide a laminator device in which the coating object does not pass the cutter during the thin-plex laminating operation and the coating object does not pass the separator in the normal laminating operation.

By the above configuration, in the case where the thin-flex film laminating operation and the normal laminating operation are performed, there is an effect that the path of the coating object is discharged differently.

Referring to FIG. 3, the cold film laminating operation according to the present invention is enabled by attaching a cold film roll to the cold film support shaft 122.

Here, in the process of performing the cold film laminating operation, the separator 180 is not used, but the thin flex film except that the cutter 190 mounted on the rear side of the drawing roller 170 is used. The description of the same matters as the laminating process will be omitted.

And, it turns out that the hot film laminating work in the laminator according to the present invention is also possible. In detail, in order to perform the hot film laminating operation, the hot film roll support shaft 124 provided on the lower side of the laminator 100 (see FIG. 1) and the cold film hanger formed at one end of the film roll holder 200. It is possible to attach a hot film roll to the groove 241 instead of the cold film roll, and only the cold film laminating process will be described below.

First, the cold film wound on the cold film roll 140 is wound on the outer circumferential surface of the thermal pressure roller 160 is the same as the thin-film laminating. Meanwhile, the cold film wound on the cold film roll 140 may include a coating layer 142 adhered to the coating object, a fabric layer 143 attached to a lower side of the coating layer 142, and an upper portion of the coating layer 142. It consists of a release layer 141 attached to the surface. The release layer 141 is separated from the coating layer 142 while passing through the tension pulley 165. In addition, the separated release layer 141 is wound around the rewinder 150.

In addition, the cold film in a state in which the release layer 141 is separated is bonded to the coating object by the thermal pressing roller 160. In addition, the coating object 300 having the coating while passing through the thermal pressing roller 160 is cut by the cutter 190 mounted on the rear side of the drawing roller 170.

In detail, the cold film laminating is not separated from the coating layer 142, unlike the thinplex laminating operation. Therefore, the fabric layer 143 should be cut by the cutter 190 in accordance with the specification of the coating object.

Finally, when the distal layer 143 is cut by the cutter 190, the coating object becomes one complete coating.

By the laminator device according to the present invention constituting the above configuration, there is an effect that the thin-plex laminating work and the normal laminating work can be made in one device.

In addition, in the case where the thin flex film laminating operation and the normal laminating operation are performed, there is an effect that the path of the coating object is discharged differently.
