Patent DE-3730577-A1 (DE)
IPC: B23P19/00
Filed: 1987-09-11
Abstract: A device (10) sorts out bolts provided with heads, such as screws, rivets or the like and distributes them among the inlets of several subsequent pneumatic conveyor lines (62). The sorting means (10) have discharge chutes (26) arranged before the entrance of the pneumatic conveyor lines. Each discharge chute (26) is provided with a closure body (40) formed by a pneumatically or hydraulically actuated rotary valve with locating throughholes (38) for each individual head bolt sorted in the corresponding discharge chute. The outlets of the discharge chutes are offset by about 90 DEG  with respect to transition channels (58) leading to the pneumatic conveyor lines. A 90 DEG  oscillation of the closure body allows the locating throughholes (38) of the closure body (40) to be selectively aligned with the discharge chutes or their associated transition channels (58). Individual head-bolts sorted through the discharge chutes in the locating throughholes can thus be conveyed to the subsequent conveyor lines, through the transition channels when the closure body is switched over. Depending on the direction of rotation of the closure body when it is switched over, the head bolts can be selectively transferred into the pneumatic conveyor lines head-first or free shank-end first.
