Abstract
An arrangement for feeding parts, which comprises a storage bin for the parts, a conveyor for moving the parts from the storage bin in a feeding direction, apparatus for orienting the moving parts arranged rearwardly of the conveyor in the feeding direction and comprising different conveyor paths, and a distributor associated with the orienting apparatus, the distributor including a transfer device capable of assuming respective positions cooperating with respective ones of the conveyor paths, a drive for imparting the respective transfer positions to the transfer device, a control for the drive, and a monitor ascertaining characteristic data of the parts and transmitting the data to the control whereby the transfer device is driven into a respective one of the transfer positions in response to the data.
Claims5
An arrangement for feeding parts having a number of orders of orientation, which comprises
- (a) a storage bin for the parts,
- (b) a conveyor means for moving the parts from the storage bin in a feeding direction,
- (c) means for singling the moving parts and for pre-orienting the singled parts to assume more than two possible orders of orientation while returning the moving parts which have not been singled to the storage bin, said singling and pre-orienting means being arranged downstream of the conveyor means in the feeding direction,
- (d) further conveyor means for moving the singled, pre-oriented parts in the feeding direction, said further conveyor means comprising
- (1) at least two conveyor paths leading to a discharge station and
- (2) another conveyor path leading back to the storage bin,
- (e) a single distributing means for the singled, pre-oriented parts between the pre-orienting means and the conveyor paths of the further conveyor means for distributing each one of the singled, pre-oriented parts to a selected one of the conveyor paths in dependence on a respective order of orientation of said part, the distributing means including
- (1) respective transfer means capable of assuming transfer positions for distributing each part to the selected conveyor path,
- (2) a drive for each one of the transfer means for imparting a respective transfer position to the respective transfer means,
- (3) a control for each one of the drives,
- (4) a monitoring device ascertaining characteristic data indicating the respective one of more than two orders of orientation of each part and emitting more than two output signals respectively corresponding to the respective order or orientation of each part, and
- (5) comparator means for simultaneously receiving and comparing the output signals from the monitoring device and more than two additional signals indicating selected characteristic orientation data indicating the respective order of orientation of each part either for return thereof to the conveyor path leading to the storage bin or for distribution to one of the conveyor paths leading to the discharge station, and for transmitting output signals to the drive controls when the output signals from the monitoring device and the additional signals conform, a respective one of the transfer means being driven in response to the output signals from the comparator means to return the part to the conveyor path leading to the storage bin or to distribute the part to a respective one of the conveyor paths leading to the discharge station, and
- (f) further orienting means in at least one of the conveyor paths leading to the discharge station.
