Description

Automatic roll laminator {Auto roll laminater}

The present invention relates to a roll laminator, and more particularly, to a technique for coating a synthetic resin such as polyethylene, such as paper continuously fed automatically.

In general, paper or photographic paper (hereinafter referred to as work), which is relatively weak to external pressure, needs to be coated with a transparent synthetic resin material such as polyethylene on its surface so that it is preserved in its original state for a long time without changing external physical or chemical pressure. There is. Accordingly, many apparatuses for coating a film on the surface of a workpiece have been devised.

As described above, a conventional coating machine for adhering a film to a workpiece is formed by inserting a workpiece to be coated between two layers of synthetic resin films prepared in advance, and then passing a heating roller and a compression roller inside the body of the coater to form a thin film (thermal welding). The pouch method is divided into a pouch method and a roll method in which a roll film is vertically mounted and a workpiece is pushed in so that a film is formed on the upper and lower surfaces of the workpiece.

By the way, the pouch method is cumbersome to insert the workpiece manually by hand between the film produced according to the size and shape of the workpiece to be coated, the supply of the workpiece and the film is not made continuously, the coating operation time increases There is a problem.

In addition, in the roll method in which only the workpiece is introduced and coated in a state in which a roll-shaped film is mounted inside the coating machine, not only the supply of the workpiece is continuously performed, but also the process of cutting or cutting the workpiece, which has been heat-sealed, to the required dimensions In addition, there is a problem that the coating operation time is increased.

In addition, in order to form a coating film on the workpiece, a roll-type film is attached to the roller inside the main body, and in order to remove the mounted film through a heating roller, a compression roller, and the like to the discharge port, a film guide lead cardboard or the like is attached to the tip of the film. After passing through between the heating roller and the pressing roller installed in close contact with the upper and lower, a series of operations to be artificially pulled out toward the discharge port is required, and the operation is not easy.

In addition, when forming the coating film on both sides while passing the workpiece through the heating roller and the pressing roller, a predetermined static electricity is generated, so that the workpieces cannot be sequentially loaded on the discharge tray according to the electrostatic force of the workpieces, and also equipped with an automatic cutter. Even laminators (even with or without discharge trays) resulted in uneven loading, which required the manual rearrangement of the coated workpiece.

In addition, the conventional heating roller serves to increase the overall process time because the time to reach the prescribed temperature for forming the coating film is relatively long by making the surface of the steel with a relatively low thermal conductivity.

The present invention is to solve this problem, it is easy to install the roll film by installing a hinged cover that can be opened and closed, and the upper and lower heating rollers and the pressing rollers can be separated, and at the same time, the continuous supply of the workpiece is possible It is to provide an automatic roll laminator that can shorten the process time.

After being cut automatically, the discharge rollers 23 and 23 'are passed through the reed switch 26, and the counter 27 calculates the signal sent from the reed switch 26 to sequentially count the coating times. Add.

In this way, the cut film and the workpiece are transferred to the discharge tray 6, thereby completing the process. At this time, the workpiece passes through the antistatic brush 24 installed close to one side of the heating roller 13, 13 'and one side of the discharge roller 23, 23', while removing the static electricity generated by heating and pressing By being discharged to the discharge port 5 in a closed state, it is sequentially loaded on the discharge tray 6 without any separate artificial rearrangement.

On the other hand, when the roll film is not installed or exhausted, the roll film lamp is turned on to stop the operation of the automatic roll laminator. When the workpiece or the roll film is not transferred normally or the cutter does not operate normally, the paper jam lamp is turned on. By stopping the automatic roll laminator, it prevents process errors during coating.

As described above, the automatic roll laminator according to the present invention has the following effects.

First, the continuous supply of the workpiece can be shortened the coating work time.

Second, by installing a cover to open and close the main body and separately installed heating rollers and compression rollers installed in close contact with each other, it is not only easy to install the roll film, but also to clean the rollers or the inside of the machine for cleaning or paper jams.
