Title: Vertical bobbin conveyor -  has swing bobbin carriers for selective delivery to removal conveyors at different heights according to bobbin shape and batch
Inventor: KEEN BERND DIPL ING
IPC: B65H67/06
Filed: 1990-09-22
Abstract: The vertical conveyor system, to carry textile bobbins between different height levels, has bobbin carriers (10) secured to the recirculating conveyor (2) by holders (9), which allow bobbin (30, 30') movement in two ways. The control cams (20), at different points in the conveyor path, act on the holders (9) to swing the bobbin carriers (10) in one of the two possible ways. The bobbin carriers (10) can swing on a horizontal and a vertical axis, independently of each other, and the control cams (20) are switched (45, 56) according to the direction of swing movement to be given to the bobbin carriers (10). Two take-off conveyors (37, 48) are vertically over each other against the vertical conveyor system. The control (23) to tilt the bobbin carriers (10) round the horizontal axis passes round the upper deflection roller (4) for the conveyor (2) so that the position adopted by the bobbin carrier (10) before the deflection point is maintained until it has passed round the deflection roller. ADVANTAGE - The vertical conveyor gives a central feed for bobbins of different shapes and batches to be passed on to further conveyors for removal according to shape and batch, separately.
