Abstract
A device for loading and/or unloading machine tools, conveyor belts and the like, with blanks or finished components, comprises a workpiece store or magazine (1) consisting of a stack (2) of pallets (3) positioned loosely one on top of another and each having receptacles for workpieces. A transporter (5) takes pallets one after the other from the stack and transports them to an unloading and/or loading station (a) to which the pallets are shifted in timed sequence, and the workpieces are removed by a sequence-timed loading and/or unloading device (7), fed to a machine tool or suchlike, and returned again after machining has taken place. After it has been worked through each pallet is then deposited at a receiving station (11) by the transporter.
Claims3
An apparatus for loading and unloading work pieces from a work piece store comprising:
- an unloading station for a stack of pallets loosely positioned one on top of the other and each pallet having means for accommodating the work pieces;
- a restacking station adjacent said unstacking station;
- a horizontal rail extending in first direction (X);
- a transporter for picking up the uppermost pallet from said stack, lifting it to a loading and/or unloading level, shifting it horizontally in incremental steps separated by idle periods in said first direction (X) to said restacking station and lowering it at the restacking station and settling it on a support or a previous pallet and comprising a carriage mounted for movement on said rail in the horizontal direction and a member with means for engaging said pallets and vertically movable on said carriage;
- and
- a loading and unloading member movable in timed sequence horizontally in a second direction (Y) which is perpendicular to said first direction (X) for removing or depositing workpieces from or on the pallet which is on said loading and/or unloading level during the idle periods.
