Problems solved by technology

However, after the part is loaded on the press and released by the clamps, the mechanical connection is lost and the swivel joint is free to rotate and, therefore, it is no longer possible to control the position of the clamps

Embodiment Construction

[0041] figure 1 A system 100 is shown for processing workpieces in a press line, for example a multi-stage press line of the type employed in stamping metal parts 300 , such as vehicle body parts.

[0042] figure 1 The system of may be used for unloading a part 300 from a first station 201 in a press line, and for transferring the part 300 to a second station 202 in a press line. The first station 201 and the second station 202 in a press line may generally be presses, ie the system is intended for in-press processing in particular, but not exclusively.

[0043] As shown in the drawings, the present system 100 may include an industrial robot 101a, an industrial robot 101b, and at least one control unit 400 for controlling the robot 1 . A single control unit can collectively control the robot 101a and the robot 101b. A control unit that can jointly operate the robot is, for example, the control unit that includes the MultiMove function available from ABB (www.abb.com). Mult...

Abstract

A system (100) for handling parts (300) in a press line comprises two industrial robots (101a, 101b) and at least one control unit (400) for the control of the robots, wherein each industrial robot isan articulated robot with at least four axes mounted in series between a robot base (2) and a robot wrist (3), wherein each industrial robot further comprises an arm (4) that has a proximal end (4a)fixed to the robot wrist (3) and a distal end (4b) carrying an additional rotational axis (A7), a motor (43) mounted on the arm near the proximal end, and a transmission (41) between the motor and theadditional rotational axis. A method for handling parts in a press line may comprise operating the system such that the two robots jointly handle a part, or such that they each handle a part, eitherin an alternating or in a parallel mode.

Description

technical field [0001] The invention relates to a system for handling components, eg for unloading components from and / or loading components to a press in a press line, and in particular for in-press processing in a press line. Background technique [0002] It is known to use industrial robots for loading and unloading workpieces or components in press lines, such as those employed for the manufacture of vehicle bodies. [0003] In a press line, it is best to keep the cycle speed as high as possible. Cycle time includes the time the press needs to bring the workpiece into line plus the time during which the press remains open while the robot unloads or removes one part from the press and loads or inserts the next part. Also, if the transfer of the workpiece from one press to another is slow, it can become a bottleneck, and then the cycle time increases as the press waits for the workpiece. [0004] Therefore, it is best to minimize the time required to load and unload pres...
