Claims
- 1. A transfer system for multi-station presses and press working lines, comprising:at least one transfer carrier extending along at least two press stations; and workpiece-receiving devices moved along the transfer carrier in a transport direction and operatively arranged to receive and release only a front edge and only a rear edge of a workpiece in the transport direction to carry the workpiece from one station to another station and to release the workpiece at the other station, wherein the workpiece-receiving devices are arranged to be moved toward one another into a workpiece-receiving position, and away from one another into a workpiece-release position by moving the workpiece-receiving devices along the transfer carrier.
- 2. The transfer system according to claim 1, wherein the workpiece-receiving devices are arranged to be moved into an vertical position different from the workpiece-receiving position and the workpiece-release position, and to a position past the tool of a press station.
- 3. The transfer system according claim 1, wherein two mutually parallel transfer carriers are operatively arranged on both sides of the tools of the press stations.
- 4. The transfer system according to claim 1, wherein the transfer carrier is connected with a lifting unit for providing the transfer carrier with a vertical lifting and lowering movement.
- 5. The transfer system according to claim 1, wherein the at least one transfer carrier or travelling carriages disposed on the at least transfer carrier are connected with a transfer unit for a horizontal transfer movement with a maximal stroke at least as large as a center distance of two successive press stations.
- 6. The transfer system according to claim 5, wherein the workpiece receiving devices are connectable by controllable driving devices with the at least one transfer carrier.
- 7. The transfer system according to claim 1, wherein at least one adjusting drive is arranged on the at least one transfer carrier between the at least one transfer carrier and the workpiece-receiving devices for changing relative position between the respective workpiece-receiving device and the at least one transfer carrier.
- 8. The transfer system according to claim 7, wherein the at least one adjusting drive is operatively configured to provide the workpiece-receiving devices with an adjusting movement toward and away from one another.
- 9. The transfer system according to claim 8, wherein the at least one adjusting drive is configured to provide the workpiece-receiving devices with a transfer movement.
- 10. The transfer system according to claim 8, wherein the at least one adjusting drive is configured to change the workpiece-receiving devices from the work piece-release position into a vertical position.
- 11. The transfer system according to claim 1, wherein the at least one transfer carrier is operatively connected with a drive so as to be changeable into a position in which the workpiece-receiving devices are in a vertical position.
- 12. The transfer system according to claim 1, wherein the workpiece-receiving devices are provided, at least in the workpiece-receiving position thereof, with traverses extending transversely to a transfer direction and movable from the transverse direction into a vertical position.
- 13. The transfer system according to claim 12, wherein in the vertical position, the traverses are arranged to be movable, into the transfer direction.
- 14. The transfer system according to claim 13, wherein the traverses are movable into the transfer position by swivelling.
- 15. The transfer system according to claim 3, where the traverses are each operatively connected on an end side thereof with the at least one transfer carrier or travelling carriages disposed on the at least one transfer carrier, and the traverses are centrally divided.
- 16. The transfer system according to claim 12, where the traverses are each operatively connected on an end side thereof with the at least one transfer carrier or with travelling carriages disposed on the at least one transfer carrier, and the traverses are centrally divided.
- 17. The transfer system according to claim 1, where the workpiece-receiving devices have one of blades, grippers and suction devices for temporary holding and releasing of the workpieces.
- 18. A transfer system for multi-station presses and press working lines, comprising:at least one transfer carrier extending along at least two press stations; and workpiece-receiving devices moved along the transfer carrier in a transport direction and are arranged to be moved toward one another into a workpiece-receiving position, and away from one another into a workpiece-release position to carry the workpiece from one station to another station and to release the workpiece at the other station, wherein the workpiece-receiving devices are operatively arranged to receive and release only a front edge and only a rear edge of a workpiece in the transport direction, wherein the workpiece-receiving devices are arranged to be moved into an vertical position different from the workpiece-receiving position and the workpiece-release position, and moved against the transport direction to a prior press station.
