Abstract
A pneumatic conveyor system adapted for the conveyance of assembly parts comprises a tubular conveyor conduit, a pneumatically operable drive in the conveyance path defined by the conduit, a control for operating the drive and an inlet metering device associated with the conveyor conduit upstream of the drive. The metering device includes a blocking mechanism responsive to the control for cyclically blocking and unblocking the conveyance path.
Claims17
A pneumatic conveyor system adapted for the conveyance of assembly parts, comprising
- (a) a tubular conveyor conduit having an inlet and defining a conveyance path,
- (b) a pneumatically operable drive means in the conveyance path,
- (c) a control for operating the drive means, and
- (d) an inlet metering device associated with the conveyor conduit upstream of the drive means, the metering device including
- (1) a blocking mechanism responsive to the control for cyclically blocking and unblocking the conveyance path, and comprising a blocking pin movable transversely into and out of the conveyance path for blocking and unblocking conveyance through the conduit, the blocking pin being capable of retaining the assembly parts when moved transversely into the conveyance path, and an adjustment drive for moving the blocking pin.
A pneumatic conveyor system adapted for the conveyance of assembly parts, comprising
- (a) a tubular conveyor conduit having an inlet and defining a conveyance path,
- (b) a pneumatically operable drive means in the conveyance path,
- (c) a control for operating the drive means, and
- (d) an inlet metering device associated with the conveyor conduit upstream of the drive means, the metering device including
- (1) a blocking mechanism responsive to the control for cyclically blocking and unblocking the conveyance path, and
- (e) an apparatus for disentangling springs, orienting the disentangled springs and classifying the oriented springs associated with the pneumatic conveyor system, the apparatus having an outlet for the oriented and classified springs, and the conveyor conduit having an outlet remote from the outlet of the apparatus, further comprising a transfer conduit arranged between the outlet of the apparatus and the inlet of the conveyor conduit, air jet means in the transfer conduit directed countercurrently to the direction of conveyance of the springs, the transfer conduit defining a passage for the springs and having a transverse bore communicating with the passage, and the blocking mechanism comprising a blocking member slidable in the bore into and out of the passage, and an adjustment drive for sliding the blocking member supported on the transfer conduit.
A pneumatic conveyor system adapted for the conveyance of assembly parts, comprising
- (a) a tubular conveyor conduit defining a conveyance path and having an inlet and an outlet arranged for manual removal of the conveyed parts,
- (1) at least an upper portion of the conveyance path being open in the outlet area for a length less than that of the conveyed parts,
- (b) a pneumatically operable drive means in the conveyance path,
- (c) a control for operating the drive means,
- (d) an inlet metering device associated with the conveyor conduit upstream of the drive means, the metering device including
- (1) a blocking mechanism responsive to the control for cyclically blocking and unblocking the conveyance path,
- (e) an abutment at the end of the conveyance path, and
- (f) a sensing device in the end area signalling the presence of an assembly part thereat.
