Description

Embossing Forming Device for Magnetic Tape for Cards {a embossing eqipment for magnetic tape card}

The present invention is to minimize the defective rate by suppressing the generation of bubbles when laminating the magnetic tape to the card covering paper in the card where all information is recorded on the magnetic tape, such as a bank card or a transportation card.

In general, a magnetic tape in the form of a band is attached to the back of a card such as a bank card or a transportation card so that various information can be stored or computerized. Therefore, the magnetic tape is very important when the card is manufactured.

The card described above is mainly in the form of a thin synthetic resin coated paper attached to both sides of the PVC plate having a certain thickness, the magnetic tape is attached to the coated paper attached to the lower portion of the card in the form of a strip.

Since the PVC sheet, the coated paper, and the magnetic tape are mainly thermally bonded using a press with a built-in heater, air bubbles in the magnetic tape are generated due to expansion of air and deformation of materials generated during thermal bonding. This occurred.

In this way, if bubbles are generated on the magnetic tape, information recording or computerized processing is impossible, and even though the thermal bonding between the PVC sheet and the coated paper is well performed, the foam is treated as a defective product by the magnetic tape on which the bubbles are generated. Defective products were the cause of raising the overall manufacturing cost of the card.

The present invention was devised in view of the above-described problems, and its object is to provide an embossing molding apparatus for magnetic tape for card, which can minimize the defective rate generated during card manufacturing by suppressing the generation of bubbles during thermal bonding of magnetic tape. It is.

At the upper part of 21), an uneven tape 30 having a large number of uneven parts 30a is placed so that both sides thereof are supported by the support device 50, which can be achieved by the embossing forming apparatus of the magnetic tape for card. .

Hereinafter, described in detail by the accompanying drawings a preferred embodiment for achieving the above object is as follows.

1 to 5, a lower mold 21 having a cooling water circulation pipe 21a embedded therein is mounted on an upper side of the work table 10, and a heating wire is mounted on an upper portion of the lower mold 21. As shown in FIG. The upper mold 20 having the heater 20a built therein is mounted and lifted by a separate driving device 40.

One side of the work table 10 is equipped with rolls 1a and 2a, each of which is coated with synthetic resin paper 2 and magnetic tape 1, and the magnetic tape 1 and synthetic resin paper 2 are formed on top of each other. , Is transported slowly through the lower mold (20, 21).

Of course, the coated paper 2 and the magnetic tape 1 are conveyed by separate driving rollers (not shown) and are always conveyed by the tension adjusting jig 13.

On the upper side of the lower mold 21, an uneven tape 30 having a large number of uneven parts 30a is placed. On both sides of the uneven tape 30, a support device 50 is mounted to tension the uneven tape 30. It is possible to keep the tension.

According to the present invention having the above configuration, when the upper mold 20 is lowered by operating the driving device 40, the upper mold 20 heated by the heating wire heater 20a heats the magnetic tape 1. Accordingly, the magnetic tape 1 is thermally bonded to the synthetic resin coated paper 2 placed on the lower mold 21.

The heating wire heater 20a mounted on the upper mold 20 and the cooling water circulation pipe 21a mounted on the lower mold 21 heat and cool the upper and lower molds 20 and 21 to form a magnetic tape 1. ) Is to be smoothly bonded and the temperature of the upper and lower molds (20, 21) can be appropriately adjusted according to the type or material of the card.

On the other hand, the uneven tape 30 is provided on the cold lower mold 21 in a taut state, and the uneven portion 30a formed in the uneven tape 30 is heated, the upper mold 20 is lowered to the magnetic tape ( Embossing is performed by forming numerous indentations and protrusions on the magnetic tape 1 when thermally pressing 1).

When countless irregularities are formed on the magnetic tape 1, hot air is rapidly discharged through the irregularities when the synthetic resin-coated paper 2 having the magnetic tape 1 attached to the PVC sheet 3 is heat-bonded. It is possible to effectively prevent the closed end such as bubbles generated in the magnetic tape (1).

Therefore, it is possible to minimize the defective rate by suppressing the occurrence of bubbles in the magnetic tape (1) during the manufacture of the card can reduce the overall manufacturing cost of the card to increase the external competitiveness of the card manufacturing.
