Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for enclosing prepaid cards such as telephone cards one by one in a plastic bag, and more particularly to an apparatus for automatically processing a card enclosing operation in a polybag at high speed.
[0002]
[Prior art]
In general, prepaid cards such as telephone cards (hereinafter referred to as “cards”) are sold by being enclosed in a plastic bag and finally in a paper bag, except when using a vending machine. Actually, this sealing work was performed manually. In order to solve this problem, a device that automatically encloses a card in a plastic bag is eagerly desired, and several automatic enclosing devices have been devised.
[0003]
Conventional automatic sealing devices are used for sealing in a ready-made bag, or for bonding two sheets without folding the supply film.
[0004]
[Problems to be solved by the invention]
Since cards are generally gold vouchers, they must be securely sealed one by one to ensure that there is no misencapsulation, there is no error in the number of encapsulated sheets, and every time a predetermined number of cards are encapsulated, paper or resin It is necessary to wrap with a film made so that the enclosed product does not fall off. In addition, when a card such as a telephone card is handed over to the user, it is almost enclosed in a plastic bag.
[0005]
However, in the conventional automatic sealing device, it is sealed in a ready-made bag, or two sheets are bonded together without folding the supply film. When processing was performed in consideration of the fact that it did not occur, it took time to supply the film, and the processing speed was as slow as about 20 to 40 sheets per minute, and a large amount of processing could not be performed in a short time.
[0006]
An object of the present invention is to provide a card encapsulating apparatus that can solve the above-described problems and can perform an encapsulating process at a high speed of 120 sheets or more per minute.
[0007]
