In order to improve the ease of opening of a sealed packaging bag, which is made by folding or combining two sheets of thermally bondable packaging material while transporting it in the vertical direction, and then heat-sealing the necessary areas around the bag to seal the contents, Vertical automatic packaging machines with V-notches, I-notches, or multiple wave-shaped notches for opening at required locations on the heat-sealed part (e.g., Utility Model Publication No. 52-6518, Utility Model Publication No. 56-40552) is well known. Furthermore, a bag with an opening cut extending between the adhesive part and the non-adhesive part of the sealed bag (Utility Model Publication No. 60-25419)

However, the opening notches disclosed in the above-mentioned Japanese Utility Model Publication No. 52-6518 and Japanese Utility Model Publication No. 56-40552 are formed using a rotating cutter or rotating knife that rotates in synchronization with the flow of the packaging material. Therefore, in the case of the V-notch and I-notch, the formation location is limited to the heat-sealed portion in the vertical direction, and in the case of the wave-shaped notch, the formation location is limited to the heat-sealed portion in the horizontal direction. V
In the case of notches and I-notches, it is difficult to provide a large number of them in the vertical seal part in terms of equipment, and if the number of such notches is increased, the notch forming part including the above-mentioned wave-shaped notch becomes weaker, and the notch forming part becomes weaker. There were problems such as the tip of the bag being bent and distorting the appearance of the bag. Furthermore, in the case of the product disclosed in Utility Model Publication No. 60-25419, since the opening cut extends over the non-adhesive part and the adhesive part, there is a risk that the adhesive part may be damaged.
The film disclosed in Japanese Patent Publication No. 22484 had problems such as the film being thick, making it troublesome to perforate and risking damage to the heat-sealed portion. Furthermore, in both of the products disclosed in JP-A-58-160251 and JP-A-60-193805, the easy-to-open part consists of scratches caused by abrasive material, so the laminated part of the film is damaged. There were problems such as heat sealing becoming uncertain and almost impossible to implement. The present invention solves the above-mentioned problems, and allows the seal to be opened easily from any location in any direction.The unsealed part will not be accidentally opened when unnecessary, and it can be easily perforated without damaging the seal part. An object of the present invention is to provide an automatic packaging machine equipped with a perforation device for tearing, which can easily produce a sealed package with good appearance without bending of the opening part.

As explained above, according to the present invention, there is provided a guide member that continuously forms a band-shaped packaging material into a cylindrical shape, and a clasped overlapping edge in the longitudinal direction of the cylindrical packaging material from the end edge. vertical sealing means for forming a cylindrical bag by heat-sealing an unsealed portion of a predetermined width inward and the remaining folded edges of the folded palms, and a supply means for supplying a filler into the cylindrical bag; An automatic packaging machine comprising a horizontal sealing means for laterally heat-sealing the cylindrical bag at predetermined intervals to form a sealed bag,
At a predetermined position in front of the guide member, a pair of perforating rolls and a receiver are installed, in which a large number of perforating needles for perforating a large number of microscopic holes for cutting the bag are implanted on both longitudinal edges of the unsealed portion of the packaging material. Since it is equipped with a perforation means consisting of a roll, it is different from the conventional V-notch, I
To prevent the unsealing part from being accidentally opened when unnecessary, such as a notch or a wave-shaped cutout, or to damage the appearance by bending, and to allow the unsealing to be easily performed from any location in any direction. In addition, the perforation means has a simple structure and can be easily attached to existing equipment, and can also be used by heat sealing. The cutting hole can be provided in the unsealed part of a predetermined width provided adjacent to the heat-sealed part without reaching the heat-sealed part, so the cutting hole can be provided in the conventional heat-sealed part. Or, compared to methods that create scratches using abrasive materials, perforation can be performed more reliably and easily regardless of the type of film (because the film is thinner), and it does not damage the heat-sealed part. There are various effects such as no heat sealing and reliable heat sealing.
