Abstract
A work transfer device executes a generally rectilinear path of movement for progressively transferring articles between successive stations. Transverse vertical motion is imparted via a track which is bodily transversely displaced while maintained parallel with the longitudinal travel of the carriage. A roller rides in the track with longitudinal motion of the carriage. The track is displaced by a double bellcrank mechanism to shift the roller vertically and in turn impart vertical transverse motion to the device.
Claims23
In a work transfer device for progressively transferring articles to successive stations having a base on which a carriage is longitudinally shiftable, work engaging means movable longitudinally with the carriage while being shiftably mounted on the carriage for transverse shiftable movement with respect to the carriage, drive means for shifting the carriage longitudinally of the base and for shifting the work engaging means transversely of the carriage so as to cause the work engaging means to execute a generally rectilinear path of movement for progressively transferring articles between successive stations, the improvement for imparting transverse motion to the work engaging means wherein there is provided a track parallel to the longitudinal travel of the carriage and wherein a track engaging means is coupled with the work engaging means so that the two move longitudinally in unison, said track engaging means riding within the track, and means operably mounting the track on the base for bodily transversely displacing the track while maintaining the track parallel with the longitudinal travel of the carriage thereby to impart transverse motion to the work engaging means.
In a work transfer device having a base on which work engaging means repeatedly executes an operating cycle of motion in a closed generally rectilinear path to progressively advance workpieces from station to station and having longitudinal guide means, means longitudinally shiftable on the longitudinal guide means for correspondingly longitudinally shifting the work engaging means, means mounted on said longitudinally shiftable means for transverse shiftable movement relative thereto for correspondingly transversely shifting the work engaging means, means for imparting longitudinal motion to the longitudinally shiftable means in properly phased relation to the operating cycle and means for imparting transverse motion to the transversely shiftable means in properly phased relation to the operating cycle, said means for imparting transverse motion comprising a bellcrank having a pivot axis pivoted on the base and including first and second crank arms, drive means, means connecting the first crank arm to said drive means for rocking the bellcrank about its pivot axis in phased relation to the operating cycle and means connecting the other crank arm to the transversely shiftable means so that the rocking action of the bellcrank is converted to transverse motion of the transversely shiftable means, the improvement in the means for imparting transverse motion means to the transversely shiftable means which comprises a second bellcrank synchronously operated with the first bellcrank but imparting motion to the transversely shiftable means at a location spaced longitudinally of the location at which the second crank arm of the first bellcrank is connected to the transversely shiftable means.
