Abstract
A transfer device using a workpiece carrier to feed workpieces to workstations for processing. The workpieces are held firmly on the workpiece carrier by a holding device (3.1). Provided on a transfer table are guiderails that serve the linear guidance of the workpiece carrier in the “x” direction. Provided for each work station is a drive with a motor and a driving wheel that drives a double-sided toothed belt which in turn engages in a toothing of the workpiece carrier. A scale is arranged on the workpiece carrier and a stationary sensor form a position emitter whose signal enables the precise positioning of the workpiece carrier.
Claims12
A transfer device for workpieces that for the purpose of processing are feedable by at least one workpiece carrier to at least one workstation, and at least one drive that moves the workpiece carriers linearly, comprising:
- a position emitter associated with the at least one drive for registering a position of the workpiece carrier.
A method for the transfer of workpieces with a transfer device comprising the steps of:
- operating the transfer device to transfer the workpiece along a transfer path on a workpiece carrier into a destination area;
- generating a signal that corresponds to a rotational movement of a motor shaft of a motor moving the workpiece carrier;
- using the signal as an actual motor position value to control the motor;
- and
- on reaching the destination area, using a signal of a position emitter as an actual emitter position value to control the motor, the workpiece carrier being moved into the destination area.
