Continuous automatic tape dispenser

SUMMARY OF THE INVENTION The present invention relates to automated packaging equipment, and more particularly to a continuous automatic tape dispenser that is capable of tearing a piece of tape piece by piece from a roll of cut-free tape and adhering the piece of tape that has been peeled off to the article.

Tape is a versatile and wide variety of adhesive products. It can be used as a sticky material for daily life, a stationery label or a pasting material for packaging purposes. It is a very practical product in modern society.

Most of the traditional tapes are sold in roll-shaped tape rolls. Each time you use them, you need to find the exposed head end, then pull out the required length and then cut it for use. For more convenient use of tape. A number of related aids have been proposed, such as the usual tape station and a hand-held tape holder dedicated to the sticker box (with a cutter); another type of cut-free tape is proposed, and the cut-free tape is also a roll. A roll-free roll of tape is sold in rolls, but it has been cut into a number of tape sheets at the same time as the production is completed. Each piece of tape has a tear-off head without adhesive, which is like a disposable paper towel every time. In general, as long as the tearing head of each piece of tape is pinched with a finger, a piece of tape can be pulled down, and a similar tape structure is proposed in the newly-launched patent of the Republic of China, "Tear-free tape table" of the approved No. 170263. .

The cut-free tape roll or the aforementioned tear-free tape has been widely used for articles that are often manually adhered in daily life due to ease of use, for example, in a convenience store for cooking. Coffee sealing tapes, or label stickers often used by students to mark or note key points, are typical examples; such cut-free tape rolls are also used in a number of packaging applications for the attachment of goods or items or In the case of sealing operations, in the case of heavy use, the manual use of such a cut-free tape roll obviously limits the speed of packaging and thus the production capacity. This problem has to be overcome.

In order to solve the known problem that the cut-free tape roll can only be relied on by manual operation, it is difficult to increase the speed. The present invention provides a continuous automatic tape dispenser capable of continuously and automatically tearing off a piece of tape from a roll of tape-free tape and pasting the piece of tape that has been peeled off onto the article.
