Embodiment Construction

[0048] In the following description and drawings, the same reference numerals are used for the same or corresponding features.

[0049] figure 1 A handling system 10 is schematically shown, by means of which an embodiment of a method for gripping an object 12 will be explained by way of example. For example, the method may be used to selectively grab objects 12 from a container 14 having a plurality of objects 12 . It goes without saying that the method can also deviate in detail by means of the embodiments figure 1 The corresponding handling system 10 of the illustrated embodiment is implemented.

[0050] Generally, object 12 has an exterior surface 16 that delimits object 12 from the exterior (ie, toward the surrounding environment of object 12 ). Such an outer surface 16 generally has planar portions 18 and convex ridges 20 and / or outer edges 22 and / or outer corners 24 disposed between the planar portions. as from figure 1 As can be seen in, for example, the outer surf...

Abstract

The invention relates to a method for gripping an object and a suction gripper. The method for gripping an object 12 by a handling system 10, includes a robot 30 with at least one robot arm 32, a gripping device 34 which is connected to the robot arm and has a pneumatically operated suction gripper 36 having an elastically deformable contact portion 42 for contact with an outer surface 16 of the object to be gripped, an identification means 46 for identifying the outer surface of the object to be gripped and a control means 48 which interacts with the identification means and is designed to control the robot, wherein an outer surface of an object to be gripped is identified, a distinction is made between planar portions 18 of the outer surface on the one hand and convex elevations 20 or outer edges 22 on the other, and the suction gripper is made to approach the outer surface of the object to be gripped in such a way that at least a part of the contact portion of the suction gripper clings to a convex elevation or outer edge of the outer surface.

Description

technical field [0001] The invention relates to a method for gripping an object according to the preamble of claim 1 and to a suction gripper used in the method for gripping an object. Background technique [0002] For example, use this method when picking goods in a warehouse. A handling system is used here to selectively grab individual goods in a storage container and, after grabbing, move the object to another location. For this purpose, the handling systems used generally comprise a robot with a robot arm and a gripping device connected to the robot arm. The gripping device is in particular a suction gripping device comprising a pneumatically operated suction gripper having an elastically deformable contact portion for contact with the outer surface of the object to be gripped. [0003] In typical applications, storage containers contain a large number of goods, which also have different shapes, sizes and weights, for example. In particular, it is also conceivable th...
