Embodiment Construction
[0050] Figure 1 to Figure 3 An example of an embodiment of a gripper according to the invention is shown in , which can be fastened to a robot arm or to a linear operating system. The holder comprises a support device 10 with five suction points, wherein a central suction point 12 is arranged in the center and four side suction points are respectively evenly spaced (equidistantly) around the central suction point. Suction part 14. The four side suction points 14 are likewise arranged equidistantly from one another. The central suction point 12 is connected to a first suction channel 16 , while the side suction point 14 is connected to a side suction channel 18 .
[0051] A negative pressure can be applied to the side suction channel 18 independently of the suction channel 16 . In this way, the side suction point 14 and the central suction point 12 can be controlled independently, whereby the central suction point 12 can be supplied with negative pressure even without negat...
