Description

[0001]
BACKGROUND OF THE INVENTION
The present invention wraps a roll-like wide film with adhesive on both ends in the width direction when wrapping a synthetic resin container containing paper lunch, side dish, Japanese confectionery, etc. The present invention relates to a banding film cutting machine that cuts into a narrow width.
[0002]
[Prior art]
Conventionally, the lunch boxes sold at convenience stores and the like have been packaged by wrapping the entire case with a self-adhesive ultra-thin film and stacking the films on the bottom of the case to adhere to each other.
[0003]
However, it is difficult to peel off such a film that adheres to the bottom of the case. In addition, it is difficult to print on an extremely thin film, and even if printing is performed, there is a disadvantage that wrinkles are easily generated, and the printed surface cannot be maintained in a cleanly readable state.
[0004]
For this reason, in the conventional lunch box, it was displayed by sticking the seal which printed the contents and the date of manufacture on the transparent lid.
[0005]
However, the packaging work of the lunch box has become troublesome due to the cost required for the seal, the labor for attaching the seal, or the trouble of wrapping the entire case with a self-adhesive film.
[0006]
Such a problem becomes the same problem when wrapping cases such as side dishes and Japanese sweets as well as lunch box packaging.

[Problems to be solved by the invention]
By the way, in conventional packaging that wraps cases such as lunch boxes, side dishes, Japanese sweets, etc., when wrapping the case with strip-shaped paper etc., attaching both ends of this paper to the bottom of the case with vinyl tape etc. is a troublesome work, It was not suitable for mass packaging.
[0008]
In addition, when such a bandage is wound in the longitudinal direction to form a roll, the number of bandages that can be taken from one roll is limited, so it is desirable to take the bandage in the width direction of the roll. The film is easily exposed to static electricity and indoor air flow, and it is difficult to cut it with its flatness. It was difficult to supply the packaging.
[0009]
The present invention has been made in view of such circumstances, and when a case such as a synthetic resin container or paper made of bento, side dish, Japanese confectionery, etc. is encased, a roll-like shape provided with adhesives at both ends. An object of the present invention is to provide a banding film cutting machine that cuts a wide film into a narrow width in the width direction.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, a banding film cutting machine according to claim 1 of the present invention feeds a roll-shaped film provided in a casing in the direction of the opening of the casing by a feed roller driven by a motor. In the vicinity of the opening is a film cutting machine that cuts a roll-shaped strip-like film into a narrow width by providing a thermal cutter for collectively cutting the fed film in the width direction, A detector for intermittently feeding the film by detecting the feeding width of the film, a balance weight for maintaining the flatness of the film fed to the opening, and a plane of the film cut by the thermal cutter And a guide roller for guiding the flatness of the film on the exit side of the thermal cutter.
[0011]
The banding film cutting machine according to claim 2 of the present invention is characterized in that, in claim 1, the thermal cutter is fixed to the casing.
[0012]
Further, the banding film cutting machine according to claim 3 of the present invention is the belt cutting machine according to claims 1 and 2, wherein the detector that intermittently feeds the film by detecting the feed width of the film is provided in the longitudinal direction of the film. An optical sensor that reads markings provided at predetermined intervals on the edge along the edge is used, and is linked with a switch that is turned ON / OFF by following the operation of the guide roller that is lifted when the film is lifted from the opening side. According to the present invention, the film is fed and moved.
