<p>The positioning system for a can which has been filled and sealed has a frame (1) with a vertical part above the can, which first locates the seam down the can (R). At the top of this part is a pneumatic cylinder (31) with its piston rod (30) connected to a lower shaft (28) which engages a block (33) carrying the seam sensing arm (39). An extension (34) below this, with a spring around it, carries a plate (35) to hold the can in position. Alongside this part is a pair of vertical pillars (2, 3) with arms (5, 6) extending horizontally, with a second pneumatic piston (17) between them, with a toothed rack (15) mountes on its piston rod (16) to operate the rotary positioning mechanism. This in incorporated in the first vertical part.</p> |
