Abstract
A rotary transfer apparatus, comprising: a frame structure; a rotatable main shaft supported by the frame structure; a primary body connected to the main shaft; at least one first planetary shaft rotatably connected to the primary body and rotating in relation to the main shaft; a secondary body connected to each first planetary shaft; a second planetary shaft rotatably connected to each secondary body and rotating in relation to the first planetary shaft; an article transfer mechanism connected to each second planetary shaft; and an in-line cam mechanism. The article transfer mechanism is adapted for picking and placing articles, and has at least one stem connected to the second planetary shaft. Each stem has a distal end whose motion defines a product path about the main shaft. The product path has at least one apex at which point the distal end of the stem moves in an in-line motion. The in-line cam mechanism is adapted for extending the in-line motion at the apex(es) of the product path.
