Abstract:
1. A multiple axis articulated arm robot for transferring workpieces, and more particularly for transferring sheet metal parts into or from a press or from one press to another adjacently placed press, comprising a robot base, on which a movement unit is able to be pivoted about a first axis, which is vertical in an operational state, such movement unit having a pivoting part adjacent to the base, an articulated arm constituted by a top arm and a bottom arm, such top arm being connected for pivoting at one end about a horizontal second axis with the pivoting part and at the other end is connected with the adjacent end of the bottom arm for pivoting about a horizontal third axis, a rotary member arranged at the bottom arm's end opposite to the top arm, such rotary member being able to be rotated about a fourth axis extending in the longitudinal direction of the bottom arm, a pivoting member connected with the rotary member for pivoting about a fifth axis extending athwart the fourth axis, and a supporting part rotatingly connected with the pivoting member, such supporting part extending athwart the fifth axis, wherein the rotary member is mounted on the pivoting number configured so as to be turned about a sixth axis, a holding means of a lifting means, associated with the workpieces to be transferred, and more particularly a vacuum suction means, is arranged on the supporting part for rotation about a seventh axis, wherein the supporting part is directed in the direction of the sixth axis away from the pivoting member and the seventh axis is directed athwart the sixth axis and wherein the holding means of the lifting means comprised a transverse rod mounted rotably on the supporting part for turning about the seventh axis the longitudinal direction of such rod conforming to the direction of the seventh axis.
