After the film fabric 122 enters the supply unit 130, in the process of withdrawing the film fabric 122 by the withdrawal rollers 144 and 146, the second dancing bar 134 is an elastic force of the second elastic member 184. Overcoming and rotating in a predetermined direction, the first dancing bar 132 is also rotated in a predetermined direction to draw the film fabric 122 stored in the storage unit 130 to the cutting / bonding unit 150. Then, the cam member linked to the first dancing bar 132 is rotated, and the amount of light irradiated from the light irradiation unit by the cam surface of the cam member by the rotation is different from the light receiving unit, and the measured value is transmitted to the control unit and the value Control the feed motor in proportion to Then, since the supply unit 120 supplies as many film fabrics 122 as necessary in the storage unit 130 to the storage unit 130, the first and second dancing rollers 136, 138 and the first of the storage unit 130. The film fabric 122 can be continuously supplied automatically while preventing the flutter of the film fabric 122 stored in a zigzag manner between the two fixed rollers 131 and 133.

After the vinyl zipper 202 is attached to the inside of the film fabric 122 by the zipper attachment unit 220, the film fabric 122 is punched by the punching member 189, and the vinyl by the ultrasonic welding punch 260. A portion of the film fabric 122 to which the zipper 202 is attached is welded.

On the other hand, the control unit lowers the support bar 157 by acting the pressure member (194). Then, the knife member 154, which has been raised, is lowered and bonded while cutting the cut portion of the film fabric 122. Here, the buffer member 196 to mitigate the impact acting on the other end of the rotating member 192. The operation is continued by the following operation. That is, the main motor 156 rotates the eccentric cam member 158 and the link member 190 reciprocates a predetermined distance by the rotation of the eccentric cam member 158. Then, the pressing member 194 by the rotating member 192 increases the rotating force of the rotating member 192 to raise the support bar 157. Then, the knife frame 150 is raised by the lifting of the support bar 157, and the knife block 153 and the knife member 154 installed therein are reciprocated at predetermined intervals. In this process, the drawing rollers 144 and 146 move the film fabric 122 again by a predetermined interval. The product 162 cut as described above is discharged through a pair of kenbers 168 and 169 driven by the conveyor motor 161 and stored in the discharge tray 166.

Side sealer capable of attaching a zipper according to the present invention has the following effects.

First, a compact vinyl zipper with almost no wing surface is supplied using a zipper supply unit having a zipper guide member and a alignment member, and the vinyl zipper is insulated by indirect heat by using a heating member, a cooling member, and a belt member. It can be easily attached in the line which produces a plastic bag product by the sealing method.

Second, by using two vertical dancing bars without using the conventional horizontal dancing bar structure, it is possible to prevent the flutter of the film fabric, and improve the working stability and accuracy of the knife member by the correction of the air cylinder, and the adhesive force of the knife member. Enhance productivity.

Third, the mechanism for operating the knife member adopts a rotation member of the rotating member and a pressure member for accelerating the rotating force by hydraulic or pneumatic pressure instead of the direct drive method by the conventional cam method, and buffers such as shock absorbers on the other end of the rotating member.
