Abstract

A turnover device for turning over articles as they are conveyed along a production path. The turnover device comprises a frame, two spaced apart and parallel axis, first and second carrier arms mounted respectively on the axes for rotational movement, first and second meshing gears mounted on the axes respectively, and a drive motor and lever. The first and second meshing gears have pitch diameters such that, as the two carrier arms counter-rotate from a start position to a finish position, the first carrier arm will rotate through an arc of approximtely 108.degree. and the second carrier arm will rotate through an arc of approximately 72.degree.. The arms are then rotated to their start position. An article placed on a first carrier arm will drop off onto the second carrier arm and be carried back down to a horizontal orientation which is flipped end to end with respect to its starting orientation.

Dependent claims

A device for turning over an article as it advances through a production path comprising:

first and second shaft means mounted in parallel relationship to each other;
a first turning member rotationally mounted on the first shaft means for rotational movement;
a second turning member rotationally mounted on the second shaft means for rotational movement;
and
gear means including synchronously meshing first and second gears mounted respectively on said first and second shaft means for synchronizing the relative rotational movement of the first and second members with respect to each other such that the first rotational member will rotate in one rotational direction from a first, loading position, wherein it is oriented in a substantially horizontal plane, to a second, unloading position, wherein it has rotated more than 90.degree. about the first axis, as the second member rotates in the opposite rotational direction from a first, unloaded position wherein it is oriented in a horizontal plane, to a second, loaded position, wherein it is oriented in a plane substantially parallel to the first member in the second position.

A device for turning over an article as it advances through a production path comprising:

a support frame;
first and second axes rotatably mounted on said frame;
a first carrier arm mounted above the first axis for rotation with respect to the frame;
a second carrier arm mounted about the second axis for rotation with respect to the frame;
synchronously meshing first and second gear means mounted on, respectively, the first and second axes for synchronizing the relative rotational movements of the first and second carrier arms with respect to each other such that the first carrier arm will rotate in one rotational direction from a first loading position, wherein it is oriented in a substantially horizontal plane, to an unloading position, wherein it has rotated more than 90.degree. with respect to the horizontal, as the second carrier arm rotates in the opposite rotational direction from a first, unloaded position, wherein it is oriented in a second substantially horizontal plane displaced below the first horizontal plane, to a second, loaded position, wherein it is oriented substantially parallel to and spaced apart from the first carrier arm in the second position:
drive means connected to one of the first axis and second axis for imparting rotational movement thereto;
and
lever means mounted on one of the first axis and second axis and cooperating with said drive means to cause rotational movement of the one axis.
