Apparatus for fitting or drawing-off hollow bodies onto or from a core bar of the rotary plate of a processing machine

摘要

The invention relates to an apparatus for fitting or drawing-off hollow bodies (18) such as cans, tubes or the like onto or from a core bar (2) of the rotary plate (3) of a processing machine (1), which apparatus has a fitting and drawing-off finger (17) which performs rectilinear lifting movements directed towards a core bar (2) by means of a drive (4) and the end of which, facing away from the core bar (2), is connected, via a rigid connection web (16), to one end of a lifting rod (13) arranged parallel to the core bar (2) and the finger (17). According to the invention, the lifting rod (13) has, at its other end, a supporting roller (14) guided in a rail (15) and is flexibly connected to an apex of a triangular lever (5), the two other apexes in each case being connected, by means of a fixedly linked connecting rod (8 or 9) to a four-bar linkage in such a manner that the link point (12) of the lifting rod (13) performs an approximately rectilinear movement while the lever (5) performs a reciprocating movement. <IMAGE>
