Description

  The present invention belongs to the technical field of an automatic packaging machine that automatically fills and packs various packaging materials using a packaging film (packaging material). Specifically, the packaging film has a substantially cylindrical cross section. The present invention relates to a vertical sealing device for a multi-row stick type automatic filling and packaging machine that performs vertical sealing.

  For example, as shown in FIG. 1, in a multi-row automatic filling and packaging machine configured so that a plurality of stick-type packaging bags can be continuously sealed at a time, a plurality of packaging films each cut into a plurality of After winding around each former pipe configured in a row and forming into a cylindrical shape, each packaging film is vertically sealed in a substantially cylindrical shape by a vertical heat sealer, and then a horizontal seal and filling of packaging material, Through various processes called cutting, the stick-shaped package is multi-row and continuously sealed.

  This vertical heat sealer is the same as the envelope pasting method in which both ends of a packaging film wound around each former pipe and formed into a cylindrical shape are overlapped on the former pipe, and then the seal fitting is pressed and welded. There is a palm-pasting method in which both end portions of the packaging film are pulled out at right angles to the former pipe and then the overlapping portions are sandwiched and welded. The two vertical sealing methods are selected in consideration of factors such as the material of the packaging film, the type of contents to be filled in the packaging bag, and the appearance of the finished packaging bag.

When vertical sealing is performed with an envelope sticking method on a packaging film that uses aluminum foil as a base film, the seal fitting that performs the vertical sealing presses against the former pipe around which the packaging film is wound. For this reason , there is a possibility that an accident such as breaking of the aluminum foil may occur, and such a packaging film is usually formed as a vertical seal of a palm-on-hand method.

  In a multi-row stick type automatic filling and packaging machine, there is a grip-type vertical sealing device as a vertical seal that can be applied with a palm. This device performs vertical sealing by sandwiching both ends of the packaging film, which is a sealing part, with two sealing fittings. If the sealing surfaces of these two sealing fittings are solid (flat surfaces), the packaging There were cases where the film slipped without reliably grasping both ends of the film, resulting in a case where the seal width was smaller than a preset seal width, and in the worst case, a seal failure occurred. Also, after applying the vertical seal, there is a process to bend the vertical seal part to the side of the packaging bag body in order to improve the appearance of the packaging bag. The packaging bag finish was worsened. For this reason, the grip-type vertical sealing device usually uses a seal fitting with a sealing surface having a cross-cut shape or a cross-shaped shape.

  However, there is a demand for a solid film with a vertical seal due to the appearance of the finished packaging bag in the packaging film that uses aluminum foil as the base film, and a multi-row stick type automatic filling packaging that can manufacture such packaging bags. The opportunity was sought.

  Therefore, the technical problem of the present invention is to provide a multi-row stick type automatic filling that can be firmly gripped at both ends of a packaging film wound around a former pipe and formed into a cylindrical shape to give a solid joint. An object of the present invention is to provide a grip type vertical sealing device for a packaging machine. It is another object of the present invention to provide a grip-type vertical sealing device for a multi-row stick type automatic filling and packaging machine that can easily bend a joint-attached portion to which a solid vertical seal has been applied to the packaging bag body side.

(1) In order to solve the above problems, the present invention is such that a packaging film is wound around a plurality of former pipes and formed into a substantially cylindrical cross section, and then both ends of the packaging film are formed in a palm shape. A grip-type vertical sealing device of a multi-row stick type automatic filling and packaging machine that vertically seals, wherein a plurality of vertical grooves are attached to the tip portion of the sealing surface of the vertical sealing device, and the vertical sealing device The other part of the sealing surface is composed of a solid pattern, and the vertical sealing device securely holds the both ends of the packaging film formed into a substantially cylindrical cross-section with a plurality of vertical groove sealing surfaces and sticks the joint of the solid pattern. together create a seal portion, is added a constant creases by the vertical groove sealing surface, butt seaming seal portion of the solid th and wherein Rukoto Do and readily folded packaging bag body That.

According to the grip-type vertical sealing device of the multi-row stick type automatic filling and packaging machine described in (1) above, both end portions of the packaging film wound around the former pipe and formed into a cylindrical shape are formed into a plurality of strips . The fluted seal surface can be securely grasped and solid joints can be applied.

In addition, the palm-attached portion provided with a solid vertical seal can be easily folded to the side of the packaging bag body by a fixed crease added by the vertical groove seal surface .

As described above, according to the present invention, in the seal fitting of the grip type vertical sealing device of the multi-row stick type automatic filling and packaging machine, by providing a plurality of vertical grooves and a solid sealing surface, the former pipe It is possible to provide a vertical seal device that can securely grip both ends of a packaging film that is wound around and is formed into a cylindrical shape and that can be applied with a solid joint. In addition, there is an advantage that a vertical sealing device can be provided that enables a packaging bag that can easily bend a joint-attached portion with a solid vertical seal to the packaging bag main body side to be sealed.
