Feed apparatus for transfer press

An apparatus for the clocked longitudinal transport of workpieces between at least two processing stations in a transfer press,

• wherein the apparatus at least on one side as a control group has a first control element and a second control element which are displaceable exclusively in a longitudinal manner,
• wherein the two control elements are mounted so as to be mutually displaceable exclusively in the longitudinal direction, and both control elements are driven by way of a common shaft;
• wherein the first control element is a gripper rod for the longitudinal transport of the workpieces between the processing stations,
• wherein at least two gripper elements which in the longitudinal direction are offset by the spacing between the processing stations and can be displaced exclusively in the transverse direction are mounted in the gripper rod;
• wherein the second control element is a thrust rod which positively controls the transverse movement of the at least two gripper elements
• wherein the gripper elements have at least one recess or through opening which in the form of a gate is open in a vertical direction, and
• wherein the thrust rod has an extension or pin which, so as to positively control the transverse movement of the gripper elements, engages in this gate in each case at the position of the corresponding gripper element;
• or
• wherein the thrust rod at the position of the corresponding gripper element has in each case at least one recess or through opening which in the form of a gate is open in the vertical direction, and wherein the gripper elements have an extension or pin which, so as to positively control the transverse movement of the gripper elements, engages in this gate.

• and
• wherein the second control element is a thrust rod which positively controls the transverse movement of the at least two gripper elements
• wherein the apparatus on both sides of a longitudinal row of processing stations has first and second control elements of this type;
• and
• wherein either the transverse movement of the respective transversely opposite gripper elements are positively controlled in a mirror-symmetrical manner in terms of the workpiece position;
• or
• wherein a sprung gripper is disposed only on one side of the workpiece, and an unsprung gripper is disposed on the opposite side, and the transverse movement of transport means, or
• gripper elements, respectively, disposed on opposite sides of the workpiece is positively controlled so as not to be mirror-symmetrical in terms of the workpiece position.
