PURPOSE:To set a sealing position to a specified position without the movement of a conveyer by providing an elevating device which elevates a holder which holds a pivot at the base end of a sealing device along a base. CONSTITUTION:A sealing device 7 consists of an upper frame 7A and a lower frame 7B whose base ends are pivoted by a pivot P1, and fixed on the upper portion of a pair of supporting side plates 9A where a pair of right and left pivots P1 pivoted on both sides of the base ends serve as a first holder. This side plate 9A is slidably installed along a rear side of a base 2 and mounted via a fixture 8 at the middle so that the height can be freely adjusted. On the upper frame 7A and the lower frame 7B, the lower end of a pair of front and back rods 14A, 14B whose upper ends are pivoted to the side wall is pivoted to a lever plate 15, and an operating plate 16 is fixed to a pivot P2 provided at the center with the lower end of the operating plate 16 pivoted to the tip of the rod of an air cylinder 17. Extension of the air cylinder 17 therefore enables the lever plate 15 to be tilted and displaced to have the sealing portion adjusted to the optimum level. |
