Abstract
A handling device for repositioning parts having a pivot arm able to be pivoted about a first pivot axis and a handling part adapted to bear a gripper and able to be pivoted with respect to a second pivot axis. The handling part is furthermore carried so that it may be radially moved in relation to the second pivot axis and cooperate by way of a cam follower with a path setting cam having two linear terminal sections. During operation of the device the handling part may move along a handling path, which has two linear terminal sections.
Claims21
A handling device for the repositioning of parts comprising a pivot arm able to be driven by a drive means to perform an oscillating movement about a stationary first pivot axis, a handling part serving for carrying a gripper, which while performing a second pivot movement is able to be pivoted about a stationary second pivot axis and furthermore is able to be set radially in relation to the second pivot axis while performing a linear stroke, and further comprising a path setting cam extending at least partly around the first pivot axis, and having two linear terminal sections, the handling part including a cam follower being engaged with the path setting cam and an entrainment member coupled to the pivot arm such that, the cam follower is able to be moved radially by the pivot arm with respect to its first pivot axis and the pivot arm so acts, during its first pivoting movement, in a driving manner on the cam follower that same is shifted along the path setting cam and accordingly the handling part moves, during each handling cycle, along a handling path, which has two linear terminal sections, in which the handling part respectively performs exclusively a linear stroke.
A handling device for the repositioning of parts comprising:
- a support body;
- a drive means disposed on said support body;
- a pivot arm driven by said drive means to perform an oscillating pivoting movement about a stationary first pivot axis;
- a path setting cam supported on said support body, said path setting cam defining a path extending at least partially around said first pivot axis and having two linear terminal sections;
- a handling arm including a cam follower engaged with said path setting cam and an entrainment member coupled to said pivot arm, said handling arm being driven by said pivot arm about a stationary second pivot axis, wherein said cam follower moves along the path defined by said path setting cam;
- and
- a handling part movably carried by said handling arm, said handling part being coupled to said handling arm cam follower such that said handling part pivots with said handling arm about said second pivot axis and translates linearly with respect to said handling arm when said cam follower moves along said linear terminal sections of said path defined by said path setting cam.
