るものである。 Conventionally, it has been common for general-purpose packaging machines to perform a series of automatic operations such as opening, filling, and melt-sealing packaging bags with chucks. As shown in Fig. 5, the packaging bag with a chuck a has two parallel engaging protrusions c on one side of the inner surface near the bag opening and a single protruding protrusion d on the other side so as to engage with each other. This is a part of the chuck e, which is melt-sealed at the position shown in the figure by a pair of melt-sealing bars at the melt-sealing station. The chuck e of the bag a is closed by sliding and engaging the chuck e while applying pressure manually.

装の体裁を損ずる。 However, packaging bag a does not have an opening until it is sealed.
Since filling is performed, there is no guarantee that both sides of the bag opening are aligned correctly just before melt-sealing, and the front side f and rear side g may be misaligned. As a result, the engagement protrusion c and the protrusion d are also displaced upwardly from each other, which not only requires manual effort in the above-mentioned chuck closing operation and takes time for meshing engagement, but also causes the engagement protrusion c and the protrusion d to shift upward. If the relative positional deviation between c and the protruding strip d is severe, there is a risk that the chuck e may come off before it is displayed in a store. Since the sides g cannot be stretched, vertical wrinkles may remain below the melt-sealed portion after melt-sealing, which spoils the appearance of the package.

溶封装置に係るものである。 The present invention aims to eliminate these drawbacks, and includes a chuck in which two parallel engagement protrusions on one side of the inner surface of the bag opening and a single protrusion on the other side can be engaged with each other. In a packaging machine that grasps the left and right vertical edges of a packaging bag with a chuck with a pair of clamping pieces that approach and move away from each other, and that sequentially stops at a plurality of stations including a welding station and transfers intermittently, A pair of interlocking arms that swing are provided, one interlocking arm is provided with a chuck tightening bar corresponding to the chuck on the front side of the packaging bag, and a sealing bar on the upper part of the bar, and the other interlocking arm is provided with a chuck tightening bar corresponding to the chuck on the front side of the packaging bag. A chuck tightening bar corresponding to the chuck and a sealing bar on the upper part of the bar are provided, and the chuck tightening bar pair on the front and rear sides is placed in pressure contact with the packaging bag in advance. This invention relates to a chuck-clamping and melt-sealing device for a packaging bag with a chuck, characterized in that one or both chuck-clamping bars are provided with a spring that allows the chuck to move freely relative to each other.

間を除くことができる等の諸効果をもつ。 As clarified by the description of the above embodiments, the present invention is applicable to the commonly used melting bars 19, 39.
A pair of tightening bars 24, 30 are installed correspondingly to both outside sides of chuck e of packaging bag a with ，
39 is operated in the conventional manner to melt-seal the bag opening, and since the engaging protrusions c and d constituting the chuck e of the packaging bag a are more rigid than the bag body,
The closing action performed before melt-sealing stretches the bag opening in the width direction and leaves no wrinkles, so not only does the appearance of the melt-seal remain intact, but the chuck of the packaging bag is closed by engaging it before melt-sealing. Therefore, even if there is some misalignment between the engagement protrusion c and the protrusion d in the height direction, accurate engagement occurs due to mutual sliding, and the sealing bars 19 and 39 subsequently close the bag. When the opening is pressed, one of the chuck tightening bars 24 (if the chuck tightening bar 39 is equipped with a spring, both chuck tightening bars 24 and 39) escapes relative to each other due to the spring 23, and the bag is melt-sealed. It has various effects such as being able to completely eliminate any deviation in the melt-sealing of the opening, and also eliminating the need for manual operations to close the chuck after it is released from the packaging machine after melt-sealing.
