Description

End folding automatic tape cutter

The present invention relates to an end-folding automatic tape cutter which, while cutting a tape, folds the end of the tape to form a non-adhesive portion, when the locking projection at the lower end of the folding device pulls the front end of the tape wound on the roller The support portion of the front end of the lower support device rises together while supporting the tape, thereby maximizing the end folding success rate.

For the packaging operation of various products, in the case where the tape of a predetermined length is continuously required, in order to provide the tape more easily, the tape automatic cutting supply machine is used, and the applicant's prior Korean registered patent No. 11095730 is one of them. The tape cutter has a tape setting groove on the rear side thereof, and the upper portion on the front side has a control portion, and the front surface of the front side of the tape cutter has a cutting portion formed with a discharge hole through which the tape is disposed. The tape of the roll on the roller is cut to a desired length and discharged to the discharge hole.

Use the tape supplied in this way, or cut the tape one by one with scissors or a knife to pack or stick the product. After the tape is cut in this way and adhered to a predetermined position, it is difficult to remove the adhesive tape in the future.

Not only is it difficult to remove the tape that has been tightly adhered, but it also has the disadvantage of tearing the corners of the tape that has been pasted or causing damage to the product.

In this case, if one end of the tape is not pasted and separated from the adhesive surface, the portion can be grasped and easily torn.

However, whether it is the usual use of scissors or a knife to cut the tape, it is cumbersome and unreasonable to fold the tape supplied by the automatic cutting one by one to form a non-adhesive surface.

The tape cutting unit folding device (Korean registered utility model publication No. 20-0126255, Patent Document 1) discloses a technique for solving these problems and facilitating folding of the tape end portion and cutting.

In the above technique, a lever is disposed on a working shaft of the scissors, and a scraping piece is disposed at a front end of the roller support frame, and the scraping piece is connected to the lever through a connecting rod, and works together with the scissors, thereby configuring While cutting the tape, fold the ends of the remaining tape.

In this technique, at the moment when the scissors cut the tape, the inner side of the upper blade presses the tape, the lower end of the upper blade is lowered to the position of the lower end of the tape, and the upper portion of the tape is scraped upward to scrape the tape, thereby folding the end of the tape.

However, the above-described technique differs in the strength at which the tape is stuck to the roller depending on the strength of the adhesive component of the tape or the temperature and humidity conditions during the operation, when the tape is pressed by the blade and is wound on the roller. In the case where the above force is strong, the tape may be torn when scraped.

Further, in order to lower the scraping piece without colliding with the upper roller, it is necessary to form a locking piece, a spring, a locking hole, and the like. However, these structures have poor durability, a complicated structure, and an increase in product cost. problem.

In addition, the "end-folding type tape cutter" (Korean Patent Publication No. 10-0853867, Patent Document 2) discloses a device for cutting a tape and folding the end of the tape in the shape of a pistol.

However, the above technique performs cutting in a state in which the lever is retracted once, and then the end portion of the tape is folded in a state of being retracted, and the tape is temporarily bonded to the front curved rod in the process of folding the tape, due to the adhesiveness of the consumed tape. The adhesion between the ends is not smooth, and since the adhesive component is adhered to the curved rod, there is a high possibility of malfunction, and thus it is substantially difficult to use.

The end side is rotated in the counterclockwise direction in a state where the non-adhesive portion 21 is formed.

In this process, during the rotation of the support device 400 mounted on the lower support member 300 connected to the lower portion of the revolving frame 100 in the clockwise direction, as shown, the fulcrum of the support portion 410 at the uppermost end becomes the tape 20 The fulcrum that moves directly to the discharge hole 12a, that is, the upper end of the support portion 410 becomes a position that coincides with the bottom surface of the discharge hole 12a.

In particular, in the state of FIGS. 9 and 10, although the locking projection 210 applies the force of pulling up the end portion of the tape 20, the tape 20 adheres to the fifth roller 13f due to the strong adhesive force, and thus may be The tape 20 is torn. However, as shown in the figure, the support portion 410 of the support device 400 moves upward while being on the fifth roller 13f. When the tape 20 is pushed up between the unevenness 13g, the tape 20 wound on the fifth roller 13f of the locking projection 210 can be more easily detached.
