Abstract

PURPOSE:To prevent peeling by performing perfect welding with a synthetic resin being a film substrate, by heating a film superposed part to be welded under pressure by a hot knife while simultaneously vibrating said hot knife in a press direction and a right- angle direction. CONSTITUTION:A film 3 is pinched under pressure and heated by an edge 6 in a welding part (d) and the outer peripheral surface of a pressure receiving roller 13 and the press pinched part of the film 3 is melted. In this state, the traverse vibration of a vibrator 10 is transmitted to the welding surfaces of an upper and a lower films 15, 15' which is doubly superposed through the edge 6 by folding back a fold superposed so that anti-fog treated surfaces are directed inside to a conveying direction and the anti- fogging agent interposed between surfaces to be welded is excluded by the mutual traverse sliding between the surfaces to be welded of the films 15, 15'. In the next step, both films are welded by a synthetic resin layer being the substrate of the film 3. At the same time, the leading end of the film 3 projected to the left of the welding part (d) is pinched and drawn to a left direction by an upper and a lower conveyors 16, 16' and cut at the welded part of the film but, because the upper and the lower films 15, 15' at the leading end edges 17 of the cut part are already welded mutually by the previous operation of the welding part (d), the cut part is formed into an individual side-seal type bag article 2.

Since a treatment substance such as an antifogging agent is present in the process and inhibits welding, complete welding cannot be achieved, and the welded part is therefore prone to peeling off.

) is used as a base machine to produce a side-seal type bag (2) with the same treated surface as the inner surface. The bottom of the bag (2) is formed by folding the folds in the conveying direction with the heat-proofing treated side facing inside, and the bottom part of the bag (2) is formed in the conveying section (C).
- At the same time, the tension and conveyance timing of the film (3) are adjusted, and the film (3) is intermittently conveyed to the welding part (d) by the width length of the bag body (2). ) is covered with the same film (3) to form the side edge (4) of the bag (2).
) At the top, a hot knife (5) is arranged with its blade line in the horizontal direction, and the knife (5) is made of metal and has an approximately pentagonal cross section, and an edge (6) is formed at the bottom. An electric heater (7) is built in to heat the knife (5) to approximately 30°C, and the top of the knife (5) is attached to the bottom of the support frame (9) via an insulator (8). A vibrator (10) is attached to the upper surface of the support frame (9), and the lateral vibrations of the vibrator (10) are transmitted to the hot knife (5) via the support frame (9) and the insulator (8). Both ends of the support frame (9) are attached to the left and right ends (11), (11), which are erected at the left and right ends of the welded part (d), so that they can be slid laterally. and the same rod (11), <11)'
The interlocking mechanism (12) built in the machine base (e) moves up and down in synchronization with the intermittent conveyance operation of the conveyance unit (C).
), and the rods <11) and '(11
) - The operation is configured to reach the bottom dead center while the conveyance operation is stopped, and to press the film (3) between the edge (6) and the pressure receiving roller (13) described below at the bottom dead center, The pressure roller (13) presses an edge (
6), and the same roller (1
3) is interlocked with the intermittent interlocking mechanism (14) in the machine stand (e), so that the left and right rondos (11), (11) stop rotating at the bottom dead center, and rotate to the left when the film (3) is transported. The outer peripheral surface of the roller (13) is lined with silicone rubber that has heat resistance and appropriate elasticity, and the film (3) has a right and left rond in the welded area (d). (11), (11)' At the bottom dead center, the film (3) is pressed and heated between the edge (6) and the outer peripheral surface of the pressure-receiving roller (13) to melt the pinched part of the film (3). At the same time, the upper and lower films (15) are laminated with the anti-fog treated surface as the inner side through the edge (6) through the transverse vibration of the vibrator (10).

15) Due to minute lateral sliding between the welded surfaces, at the same time, the welded part (d) of the same film protruded to the left. The film (3) is pinched and indexed and separated at the welded part, but the upper and lower films (1) at the tip edge (17) of the separated part
5) and (15)- have already been welded to each other in the previous welding part (d) operation, so the separated part is formed into an individual side seal type bag body (2), and the same upper and lower conveyor The bag body (2) is manufactured by repeating the operation of conveying it to the bag receiving stand (18) at (16) and (,16)'.

By creating a slight sliding movement between the welding surfaces of the film, intervening substances that inhibit welding between the welding surfaces are eliminated and complete welding is achieved, thereby preventing peeling.
