Description

Detailed Description of the Invention (Technical Field) The present invention provides a method for manufacturing a long strip film along its longitudinal direction.
The 4L packages are stacked in half and fed at equal intervals between the upper and lower facing film surfaces, and the film is made into a tube by continuously welding the palms on both sides of the film. The present invention relates to a bag-forming-filling-packaging device that welds and cuts the tube. More specifically, a is a type of device in which both sides of the film are formed on the sides of the tube, and as a result, the seal line is formed on the side of the packaged product.

(Prior art) This type of packaging device is known, for example, from Japanese Patent Application Laid-Open No. 58-9322.
It is also disclosed in Publication No. 7. This is the type of bag making, filling and packaging equipment that is most in demand and forms the gassho seal line on the underside of the tube. This type of packaging, which is in high demand, has a good appearance because the gassho seal line is hidden under the packaged product, and it can be colored to attract the film to the top surface of the packaged item, so it is relatively easy to use with the film. Although it has the advantage of reducing the space between it and the object to be colored, it is difficult to work in the narrow area under the slicing device, so it takes time to change the film, and the device itself is complicated and expensive. It is. On the other hand, the packaging device of the type proposed in this application is unsightly because the gassho sole line is formed on the side of the packaged product, is relatively inexpensive, is suitable for small businesses, and is made of film. It is easy to replace, and since there is plenty of space inside the bag, it is suitable for packaging items with different sizes, so there is a certain demand for it. However, due to the characteristics of this type of packaging equipment, there is a limit to the length of the tenon.

In other words, in order to expand the four essential points of this type of packaging equipment, it is necessary to bring the film and the packaged object into contact with each other as much as possible so that relatively tight packaging products can be produced, and to reduce the area used for the film. It is necessary to consider the following:

(Problems to be Solved by the Invention) The present invention solves the above-mentioned problems by making it possible to use tension packaging and film interchangeability in A-mikono 1's packaging.

(Means for Solving the Problems, etc.) In order to accomplish one of the above objects of the present invention, there is provided a belt conveyor for carrying in temporary color coating, and a tube-making mold of a film provided so as to surround the belt conveyor for carrying in. , a film tension belt at the rear of the conveyor belt conveyor and the tube-making mold; a center loop on the side of the film tension belt for welding the palms of both sides of the film; and a rear film tension belt at the rear of the film tension belt. In the apparatus in which the ffi portion perpendicular to the longitudinal direction of the film is coated with a cross sealer, the guide element is vertically installed from the frame of the conveyor belt for carrying in the film. 8. A one-way mold is supported on the guide element so as to be able to move. A rail is provided on the lower side of the carrying belt conveyor, and a rail is provided perpendicular to the direction of film flow. The belt conveyor and the cylindrical mold are integrally supported on the guide so as to be movable along the rail.

According to the invention, therefore, along the guide elements vertically erected from the frame of the inlet belt conveyor! ! ! Since the simple mold is movably supported and the cylinder mold can be moved vertically relative to the conveyor belt, the gap between the top surface of the belt conveyor and the ceiling of the cylinder mold above it can be reduced. The thickness can be adjusted according to the size of the packaged item, and unnecessary voids can be eliminated inside the film. In addition, compared to the center loop whose installation position is fixed, the belt conveyor for carrying in and the cylindrical mold are moved laterally together along the rails, so the film can be adjusted to fit the volume of the packaged items. Depending on the width, the palms on both sides of the film can be aligned with the center loop.

(Example) An example of the present invention will be described based on the drawings. In the example shown in FIGS. A film cylinder mold (21) surrounding the film, and a film tension belt (3) located behind the carrying belt conveyor and cylinder mold.
