A rotary transfer member carries means for picking up a sheet-like article from the top of a supply stack supported within a hopper having an open top and an open bottom. An indexing mechanism includes means for intermittently rotating an output shaft in response to a continuously driven input shaft, and the transfer member is supported for rotation with the output shaft and also for axial movement relative to the output shaft. The transfer member is moved axially in response to linear movement of a follower which engages a cam connected for continuous rotation with the input shaft. Supply stacks of articles are successively elevated into the hopper from an index table by a power driven jack mechanism, and a set of magnets are positioned adjacent the hopper for magnetically spreading and spacing the articles within the upper portion of the supply stack within the hopper.
Apparatus for transferring articles, comprising means for supporting a stack of articles, means for continuously supplying articles to the bottom of the stack, a transfer mechanism including a rotary input shaft and a rotary output shaft, first cam actuated means for intermittently indexing said output shaft in one direction in response to continuous rotation of said input shaft in one direction, a transfer arm including means for engaging each article on the top of the stack, means connected to said output shaft and supporting said transfer arm for indexing with said output shaft and for axial movement relative to said output shaft, second cam actuated means driven by said input shaft for producing reciprocating axial movement of said transfer arm in response to said rotation of said input shaft for moving said article engaging means to pick up an article on the top of the stack, and said first cam actuated means cooperate with said second cam actuated means to produce synchronized compound rotary indexing and axial movement of said transfer arm and said article engaging means in response to continuous rotation of said input shaft for successively transferring articles from the stack.
Apparatus for transferring articles, comprising means forming a hopper for receiving a stack of articles, said hopper having an open top and an open bottom, means for elevating a supply of articles upwardly through said bottom of said hopper to provide for continuously supplying articles to the stack, a transfer mechanism including a rotary input shaft and a rotary output shaft having parallel spaced generally vertical axes, first cam actuated means for intermittently indexing said output shaft in one direction in response to continuous rotation of said input shaft in one direction, a transfer arm including means for engaging each article on the top of the stack, means depending from said output shaft and supporting said transfer arm for indexing with said output shaft and for axial movement in a generally vertical direction relative to said output shaft, second cam actuated means driven by said input shaft for producing reciprocating generally vertical axial movement of said transfer arm in response to said rotation of said input shaft for moving said article engaging means to pick up an article on the top of said stack, and said first cam actuated means cooperate with said second cam actuated means to produce synchronized compound rotary indexing and axial movement of said transfer arm and said article engaging means in response to continuous rotation of said input shaft for successively transferring articles from the top of said hopper.
