A device and process to facilitate the high speed placement of articles onto moving objects by coordinating the velocity of the articles with the velocity of the moving objects. The device comprises a frame structure, a rotary transfer mechanism having an intermittently oscillating center gear and having a plurality of planetary gears in rotational communication with the center gear. An article transfer mechanism is provided having activatable article holding structure and being in fixed rotational communication with at least one planetary gear to impart orbital motion to the articles being transfered. The orbital motion provided by the article transfer mechanism has at least two outwardly extending apex positions. The device has a drive source and a synchronized advancing mechanism which is constructed and arranged to oscillate the center gear at predetermined times as the article holding structure approach as an apex position of travel.
In an article transfer device having at least one article transfer mechanism to pick, place and tranfer articles via apex positions of travel and having a synchronized travel control base member in positive rotational communication with the article transfer mechanism, an advancing assembly reciprocatingly operative on said travel control base member, said advancing assembly being synchronized with said article transfer mechanism at an apex position of travel and being constructed and arranged to vary the rotational speed of the article transfer mechanism at a predetermined position of travel, whereby the reciprocating movement of said advancing assembly controls the accurate positioning of the article transfer mechanism.
An advancing motion apparatus to impart an intermittent synchronized movement to a rotary transfer device having an article transfer mechanism, said apparatus comprising:
A device to facilitate the high speed placement of an article onto a moving object and to synchronize the velocity of the article with the velocity of the moving object, said device comprising:
In an apparatus for placing articles onto moving objects at a predetermined velocity having an article transfer device with a frame structure and an article transfer mechanism traveling in orbital motion with apex positions of travel about a center shaft and being in synchronized movement with a conveyor means for transferring objects, an advancing mechanism comprising a synchronized advancing means comprising a reciprocating structure in communication with said article transfer mechanism constructed and arranged to oscillate the article transfer mechanism and to accelerate the rotational movement of the article transfer mechanism at said apex position and synchronized drive means operative on said advancing means, said article transfer device and the conveyor means.
