Abstract

PURPOSE:To manufacture at low costs articles with high article accuracy and high merchandise value as a wrapping bag for triangular food staffs by sticking a series of cut tape before superimposition of two front and rear sheets of a plastic film, and thereafter cutting them along the conjunction lines of the upper side and lower side of the superimposed film to be mounted on an article receiving table, and finally removing the residue from the side of a bag body. CONSTITUTION:Front and rear films 1, 2 passed through working devices 4, 6 are superimposed to each other and then moved to the heat compression device 8 of a next process and, by the use of a fusing machine 8a, a lateral seal 9 is given in the proximity of the conjunction line (a) of respective upper sides of each bag row and mold seal 10 is also given in the vicinity of a conjunction peripheral part of both oblique sides and residue 11 of each bag body by a melting machine 8b. In the next place, the superimposed film fused by the heat compression device 8 is processed such that a bag manufacturing unit of four bag bodies F1-F4 are further delivered to the next cutting mechanism 12 and cut in the width direction of film from each conjunction line (a) by a cutting blade 12a, so as to be separated into a two-bag set of bag raw bodies having residue 11 at respective both sides and subsequently be mounted on an article receiving table. Each bag body and residue 11 are cut away from the mold seal 10 part by tearing.

る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a manufacturing method for producing an isosceles trapeous bag body from two front and back plastic films (hereinafter simply referred to as "film") of a predetermined width which are intermittently supplied. Regarding the bag method, the purpose is to provide a cut tape in the direction (longitudinal direction) that connects the upper and lower sides of the bag body, and use the surplus portion of the film that will eventually become cutting waste, It is intended to facilitate the alignment or the alignment of the bags stacked on the pedestal.

Description of the Related Art As packaging bags for foods shaped like triangles (hereinafter referred to as "triangular foods") such as sandwiches and pancakes, various packagings having various shapes and structures have been widely used. As shown in FIG. 4, the basic bag shape is obtained by polymerizing two front and back films (a) and (b) whose plane shape is an isosceles trapezoidal shape and excluding the lower side (c) of the other three sides ( D) (e) (f) are welded together.

Alternatively, a means of providing a narrow cut tape (g) has been used.

The arrangement of the bag (F) as shown in [B] is [A] in the same figure.
It can be said that this is a rational arrangement in that there is no generation of excess film (h) that becomes cutting scraps, as shown in Fig. 5, but in both cases of [A] and [B] in the same figure, it is cut individually. The bags (F) that are dropped and stacked one by one on the product pedestal are extremely thin and flexible, and are not accurately stacked because they are easily charged with static electricity. There is no other way than to rely on human hands to correctly align and align (usually 100 sheets), and the congestion of work in this part will limit the operation of the high-performance bag-making machine, which will increase the work efficiency. There was a problem that improvement could not be expected.

った。In either case of [A] or [B] of FIG. 5, if the cut tape (g) is efficiently attached according to the flow of the film during bag making, the bag (F) ) Is limited to a so-called horizontal tape in a direction parallel to the upper side (d) or the lower side (c), and a vertical tape, that is, to provide a cut tape (g) in a direction orthogonal to the upper and lower sides of the bag,
There was also a problem that it was technically extremely difficult or inefficient.

成するという手段を用いたものである。Therefore, the present inventor rationally provided a vertical tape on the bag body which was a neck in the conventional bag making means, and arranged the bag body on the product stand. In this case, as a result of repeated experiments and examinations concerning the efficiency of alignment, the former problem was solved by arranging the upper side and the lower side of the bag body to be connected to each other in the film traveling direction (longitudinal direction). However, regarding the latter, it is essential that at least one corner of the bag body has a right-angled portion in order to accurately and efficiently align and align this kind of bag body (F) that is extremely flexible and light by hand. To find out
By specifying the disposition of the bag body on the film as described above, a surplus portion that is finally cut and discarded is attached to each bag body to form a bag raw material, and the surplus portion forms a right angle portion. The means is used.

Assuming a row of bags arranged so that the upper and lower sides of the trapezoid are in contact with each other, a cut tape (vertical tape) is attached to one of the front and back films, and then the films are polymerized with each other. While heat-welding the upper side of the bag body (hereinafter referred to as "horizontal seal"),
Thermally weld the hypotenuses on both sides (hereinafter referred to as "mold seal"),
Next, by cutting the blade along the joining line of the upper side and the lower side of the bag body with the above arrangement, a bag original body with extra portions on both sides is formed, and a predetermined number of this bag original body is stacked on the product cradle. The means is used.

By arranging the upper side and the lower side of the body in a continuous manner so that they are joined to each other, vertical tape can be attached in synchronization with the progress of the process. By forming a bag raw material with an extra portion attached to both sides of, the bag raw material has a right-angled portion formed, so that the position of the bag raw material when stacked on the product cradle can be reliably regulated, and Even when manually stacking and aligning a predetermined number of stacked bag originals, the presence of the right-angled portion provides a special effect that the work can be performed accurately and effectively.

For example, in the bag body in which the two-line notch 5 and the through hole 7 (back film) are provided at the position straddling the joining line (a) of the front film 1,
When the front and rear bags in the cutting mechanism portion 12 are cut from the joining line (a), the cut tape 3, the two-wire notch 5 and the through hole 7 are cut at the same time, so that the cut tape knob is formed at this portion. Therefore, a convenient state for opening the triangular food after packaging is obtained.

とは当然である。In the above-mentioned embodiments, the arrangement of the bag bodies on the film is described as a two-row type, but in the present invention, the number of rows of the bag bodies on the film is limited to two. However, if the upper side and the lower side of the bag body are joined to each other and are continuous in the traveling direction of the film, it is natural that the same can be applied whether it is one row, three rows or four rows. .

う格別の効果が得られるのである。According to the production method of the present invention described in detail above, in producing a bag for packaging triangular food or the like, the upper and lower sides of the bag on the film are orthogonal to the traveling direction of the film. By setting consecutively, bags with vertical tapes (cut tapes) can be easily and easily obtained, and the excess of the film that is eventually cut off and discarded can be used for each bag original material. By forming the right-angled portion, it is possible to accurately align the bag raw materials on the product pedestal, and it is possible to obtain a special effect that the bag raw materials can be quickly and easily aligned even when manually.

である。This not only saves a great deal of labor in this part, which has been a bottleneck in the bag making process, but also improves the accuracy of bag assembly and speeds up the bag making process. As a result, the bag-making capacity is 3 ~ compared to the conventional one.
In addition to the four-fold improvement, it has become possible for a worker who had previously required at least one person per bag-making machine to handle several bag-making machines by one person. Combined with precision, the remarkable effect that a product with high commercial value as a triangular food packaging bag can be provided at low cost is brought about.
