Embodiment Construction

[0056]Hereinafter, a heat-sealing device according to an embodiment of the present invention will be described with reference to the drawings. The heat sealing device is set on the bag making machine. Hereinafter, the direction X, the direction Y, and the direction Z are perpendicular to each other.

[0057] figure 1 Shown is a bag making machine making plastic bags. The bag making machine utilizes a pair of guide rollers 7 to make at least two continuous body pieces 1 , 2 overlap each other, and is intermittently conveyed by a pair of conveying rollers 8 . Its conveying direction X 1 It is consistent with the length direction X (continuous direction) of the body parts 1 and 2 . Before the body parts 1 and 2 are overlapped by the bag making machine, the side wrapping parts 3 ( Figure 9 A. Figure 9 B) Supply to one of the body parts 1, 2, and arrange along the width direction Y of the body parts 1, 2, so that the side wrapping parts 3 are arranged between the body parts ...

Abstract

A heat-sealing device (10) of a bag-making machine includes a pair of sealing units (12, 13) facing each other in a facing direction (z). The sealing units (12, 13) respectively include heat-sealing members (14, 15) and heaters (16, 17). The heat-sealing device (10) is equipped with an adjustment unit (18), and the adjustment unit (18) moves one sealing unit (12) along the width direction (Y) of the continuous body parts (1, 2), and moves the other side The sealing unit (13) moves in the width direction (Y) along with the movement of the one sealing unit (12) in the width direction (Y) of the body member (1, 2).

Description

technical field [0001] The present invention relates to a heat sealing device provided in a bag making machine. Background technique [0002] Various bag making machines for making plastic bags have been developed. For example, the bag making machine overlaps at least two continuous body pieces and intermittently feeds the body pieces along the length of the body piece. The bag making machine heat-seals the body in the longitudinal direction and the width direction of the body each time the body is fed intermittently. Thereafter, the bag making machine cuts the body in the widthwise direction every time the body is intermittently fed. Thus, the bag making machine makes plastic bags. [0003] Figure 9 The plastic bag of A comprises body parts 1, 2 overlapping each other. The side wrapping part 3 and the bottom part 4 are disposed between the body parts 1 and 2 . The side wrapping member 3 has been folded in half. One end of the side wrapping member 3 is folded in betwe...
