US 6,185,979 B1 · Traverse-type three-axis transfer system

Abstract

A transfer system is provided for press facilities with several successive press stations. The transfer system has divided cross traverses which, with respect to the transport direction, can be moved from the front and the rear into the tool. Each tool includes two respectively transversely divided traverses. For receiving and depositing the workpieces, the cross traverses are adjusted toward and away from one another. In addition, when the tool is closed, the cross traverse are laterally moved past the tool. As required, they may be changed for this purpose into an overtaking position, which can be carried out, for example, by a swivel drive. The transfer system permits a shortening of the minimum time for which the tools must be open with respect to the transfer system and thus allows an increase of the stroke number of the press.

Dependent claims

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.
