Abstract
An articulated-arm transport system, provided in particular for the automation of press lines and large-component transfer presses, is distinguished by a design which permits components or workpieces to be inserted or removed even when there is a small clearance between an upper and lower tool.
Claims10
A device for transporting workpieces in a press, press-line, large-component transfer press, or simulator, the device comprising:
- a machining station having at least one independent transport device for transporting the workpieces and for carrying out two-axis transport movement, the at least one transport device comprising:
- a pivoting arm, the pivoting arm including first and second pivoting arm parts mounted for movement in rotation,
- a first movement transmission means coupled to the first pivoting arm part,
- a drive motor for acting on the first movement transmission means and controlling a magnitude of a pivoting angle of the first pivoting arm part,
- a transverse crossmember having a component holding means,
- a pick-up and bearing unit arranged at one end of the second pivoting part for coupling the transverse crossmember to the second arm part,
- linear guides,
- a carriage coupled to the linear guides and mounting at least the pivoting arm,
- a second transmission movement means coupled to the carriage, and
- a stationary lifting motor for vertically moving the carriage via the second movement transmission means.
