Abstract
A transport system, particularly for forming machines for cold forming or warm forming, has a holding rail with gripper devices which are each separately controlled by way of servomotors. The transmissions provided for the force transmission between the servomotor and the clamping jaws of the gripper device can be self-locking, but transmit independently thereof the rotating movement of the respective servomotor continuously to the clamping jaws which therefore swivel. For a better control or automatic control of the gripper devices, these transmissions can be provided with sensors for detecting the force and/or the position.
Claims19
A transport system for transferring workpieces in a forming machine, comprising:
- at least one gripper device configured to grip a workpiece and having at least one movably disposed clamping jaw, and
- at least one driving device individually assigned to the at least one gripper device having a transmission for transmitting movement applied by a servo motor configured to definably control a clamping force exercised by the at least one clamping jaw and arranged to individually cause gripping and releasing of the workpiece of the associated gripper device wherein the at least one clamping jaw is disposed to be swivellable about a fixed rotation axis and is connectable via tension lugs with an output of spindle-type gearing formed by a roller-type threaded spindle.
A transport system for transferring workpieces in a forming machine, comprising:
- at least one gripper device configured to grip a workpiece and having at least one movably disposed clamping jaw, and
- at least one driving device having a servomotor and a transmission containing a spindle-type gearing and configured to transmit movement applied by the servomotor to the at least one gripper device, the servomotor being configured to definably control a clamping force exercised by at least one clamping jaw onto the workpiece wherein the at least one clamping jaw is disposed to be swivellable about a fixed rotation axis and is connectable via tension lugs with an output of spindle-type gearing formed by a roller-type threaded spindle.
