Abstract

PURPOSE:To allow production with stable card quality by providing plural endless grooves varying in transverse positions on the outer peripheral surfaces of 1st and 2nd heating and pressurizing roller pairs, providing the projections corresponding to these grooves and fitting the projections into the grooves of the roller pairs. CONSTITUTION:The 1st heating and pressurizing roller pair 62, the 2nd heating and pressurizing roller pair 63 disposed at an arbitrary spacing therefrom, and the guide members 61 provided in the inlets and outlets of the heating and pressurizing roller pairs 62, 63 are disposed. The plural grooves 62a, 63a varying in transverse positions are provided on the outer peripheral surfaces of the 1st and 2nd heating and pressurizing roller pairs 62, 63 and the projections 61a of the guide members 62 are fitted into these grooves, by which this device is constituted. The front end of a film 3 is, therefore, deformed by the influence of heat when the front end approaches the heating and pressurizing roller pair 62, but since the projections 61a of the guide members 61 are held fitted into the grooves 62a, the front end of the film 3 passes the spacing between the roller pair 62 while the front end is corrected. The same holds true of the 2nd heating and pressurizing roller pair 63. The product surfaces of the cards are cleanly laminated at all times in this way.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an improvement in a laminating section in a laminating apparatus for laminating photographic materials.

[Conventional technology]

The present applicant has proposed the following patent application for a laminating apparatus for photographic materials filed after March 5, 1990.

In other words, a photosensitive material laminating machine used to create cards for driver's licenses and identification cards laminates, one by one, a protective film coated with adhesive on one side and a card with an image recorded on the other side. The adhesive side of the film and the image side of the card are conveyed so as to face each other using separate conveyance paths and conveyance means while being synchronized with The four corners of the mask are placed so that their four corners are aligned correctly.

A pair of heating rollers, which are disposed opposite to each other on both sides of the mask, are slid by the drive of an eccentric cam and pressed into contact with the film and the card from both sides, so that the approximately central portion between the film and the card is pressed against the film and the card. The adhesive is melted by heating and pressurizing a portion of the film, and the adhesive surface of the film and a portion of the image surface of the card are bonded together. When the bonding is finished, each of the heating rollers immediately separates from the film surface and the card surface.

In this way, the film and the card, which are correctly positioned with respect to each other and a portion of which is adhered, are conveyed as one body through the next conveying section to the laminating section, which is the second stage of adhesion. The laminating section has a conveyance section equipped with a pair of heated pressure rollers that are rotatably driven and a guide plate, and the film and the card, which are partially adhered at the bonding section, are placed on the guide plate. It is conveyed between the pair of heating and pressing rollers along the line. Then, as the film passes through the film while being heated, pressurized, and rotated by the pair of rollers, the adhesive of the film is gradually melted, and the entire surface of the film and the card are bonded and laminated. The cards finished in this manner are transported to and stored in a cart placed at a predetermined position, and then collected.

[Problem to be solved by the invention]

As mentioned above, the protective film and the card are bonded together using a laminating device for photosensitive materials. There is a bonding process and a second lamination process in which the entire surfaces of the film and the card are adhered and laminated.

In both cases, the adhesive is melted and bonded together using roller heating and pressure means.

In the first step of the bonding process, the film and the card are heated and pressurized in a stationary state, and a pair of heating rollers presses a portion of the film and the card in a short time to bond them together. , because an adhesive that immediately separates is used, the adhesive rapidly cools and solidifies, causing the melted adhesive to ooze out or cause other a! There is no possibility that it will adhere to structural parts. On the other hand, in the second stage of the lamination section, the heating,
Since the pressure roller pair is constantly rotating while pressing the film and the card, when the film approaches the heating roller pair along the conveyance kite plate, the leading end of the film is deformed under the influence of heat. For example, the adhesive of the film may adhere to the outer circumferential surface of the heating roller or the guide plate, and the adhesive may be transferred to the surface of the card that will become the product, or foreign matter may adhere to it, resulting in stains. Sometimes. Further, in some cases, the film may be stuck to the card surface in a wrinkled manner, a part of the film may be peeled off, or the film may become jammed and cannot be transported.

Therefore, in order to prevent the above-mentioned problems from occurring, the photosensitive material laminating equipment must be stopped once or twice a day for inspection and cleaning, resulting in extremely poor production efficiency. A lot of effort and attention is put into maintaining and managing the high quality of the cards.
