Manufacturing equipment for cushioning material

摘要

Objective To provide an equipment which automatically manufactures cushioning material by filling air inside the polyvinyl alcohol laminated paper and sealing them into individual bags. Solution The manufacturing equipment 1 is provided with a material roll 20 to which a sheet material of polyvinyl alcohol laminated paper is wound, the sheet material 10 is rolled out by the feeding roller 40 from the material roll 20, and the sheet material 10 in a certain length, adjusted by the length adjusting device 50 having a roller 42 which goes up and down, is supplied intermittently to the bag forming device 100 located at downstream. The bag forming device 100 is provided with a pipe member 105 and a sailor 110 which is a guide plate to reverse the sheet material 10 and to form it into a tubular shape, and the sheet material 10 is fed along the pipe member 105 after being formed into a tubular shape. Feed rollers 130 and auxiliary belt 120 are arranged at the periphery of the pipe member 105. The feed rollers 130 catches the superposed sections of both edges of the sheet material formed into a tubular shape and feeds the material, then inserts the superposed section into a center sealer 150. The center sealer 150 is provided with a heater, and welds together the superposed sections. As a result of this welding, the sheet material is formed into a long tube. The center sealed tubular sheet material is further sent downstream from the lower end of the pipe member 105. The air is being supplied from the top of the pipe member 105, and the air is filled inside the tubular sheet material. In such condition, the sheet material is sent to the end sealer/cutter. The end sealer/cutter 160 is provided with a pair of end sealers facing each other, which welds the tubular sheet material to be a bag shape and cuts into individual bags by the cutter 165. At this time, the air amount is adjusted by the filled air amount adjusting device 170. The air filled cushioning material 200 is sent to the next process by a conveyor 210. <IMAGE>
