Patent number: 7484922Abstract: The invention relates to an articulated arm transport device which is especially provided for the automation of large component transfer presses. Said articulated arm transport device is characterized by a kinematics and design that do not require any additional clearance between the press rams and pillars and that permit an introduction or extraction of workpieces even with a small clearance between the upper and lower tool. The articulated arm transport device is mounted above the workpiece transport plane on the press stands. The articulated arm part linked with the cross-member is shorter than the articulated arm part and makes a pivoting movement substantially above the common pivot. A lifting and/or pivoting movement can be carried out by means of controlled lift drives that are functionally linked with transmission means.Type: GrantFiled: November 11, 2004Date of Patent: February 3, 2009Assignee: Mueller Weingarten AGInventors: Erich Harsch, Rainer Reichenbach

Patent number: 7040853Abstract: A transfer system provided, in particular, for multi-stage presses for large components is distinguished by a favorable design with a low moving mass and allows large transporting steps. By the regulation of 2 stationary drives both in the direction of rotation in relation to one another and in the rotational speed, it is possible to realize all desired traveling curves in one plane. A straightforward construction makes possible a cost-effective, modular solution for a highly dynamic transfer system.Type: GrantFiled: January 30, 2001Date of Patent: May 9, 2006Assignee: Mueller Weingarten AGInventors: Erich Harsch, Rainer Reichenbach

Patent number: 6968725Abstract: The invention proposes a transporting apparatus for transporting single or double workpieces through processing stations of presses, in which apparatus up to 9 degrees of freedom are integrated in the transporting system. Necessary changes in position for, for example, feeding into dies can take place directly by way of the transporting apparatus. It is possible to dispense with intermediate set-down locations or orienting stations.Type: GrantFiled: January 24, 2001Date of Patent: November 29, 2005Assignee: Mueller Weingarten AGInventors: Erich Harsch, Rainer Reichenbach

Patent number: 6715981Abstract: A transport system provided in particular for large-component transfer presses is distinguished by a design with a low width and, nevertheless, permits large transport steps. By controlling two drives in the direction of rotation in relation to each other, all desired travel curves in one plane can be realized. As a result of the simple construction, a cost-effective solution is achieved for a highly dynamic transport system.Type: GrantFiled: September 13, 2001Date of Patent: April 6, 2004Assignee: Müller Weingarten AGInventors: Erich Harsch, Rainer Reichenbach
