Embodiment Construction

[0039] In the figures, functionally identical elements are provided with the same reference symbols unless otherwise stated.

[0040] exist figure 1 How the objects 101 , 203 , 202 , 201 are arranged on the conveyor belt C is schematically shown in . An example would be individual products wrapped in plastic film in a packaging facility, ready to be stacked into cartons. For example every six individual products are packed into a carton and are thus delivered as a product. To this end, objects 101 , 203 , 202 , 201 are picked up from a conveyor belt C by robotic gripping arms R1 , R2 , R3 and lifted into cartons on another conveyor belt C′. For clarity, only a few objects are shown.

[0041] In a real packaging facility, the products appear on the conveyor belt C irregularly and unregulated. For example, they fall off a conveyor belt that was previously in the manufacturing facility. For example in the last step of the process a plastic film is wound around the product an...

Abstract

A method for optimizing an automated process to select and grip an object by a robot in an arrangement that includes a plurality of robots with regard to a specifiable optimization criterion, whereinthe objects to be potentially gripped irregularly occur with respect to their spatial position and a time of their arrival, where detection of objects to be potentially gripped by robots is performed,detection of a priority characteristic as well as an assignment to one of the robots for the objects to be potentially gripped via an automated learning algorithm, taking the optimization criterion into account, and where selection and gripping depending on the assignment and the priority characteristic is implemented.

Description

technical field [0001] The present invention relates to a method for optimizing an automated process of selecting and grasping objects by a robot using machine learning algorithms. Background technique [0002] Manufacturing plants or packaging plants in various industrial automation fields often have conveyor belts on which objects or products or parts of products rest unsorted or irregularly. For example, especially in the field of primary and secondary packaging, such as in the food and snack industry, it is often found a central conveyor belt, on which the products to be packaged are located. Here, the quantity and placement of products per conveying area vary. For the packaging process, one or more industrial robots, so-called delta pickers or bent-arm robots, are often used in succession to carry out so-called pick-and-place actions. This is to be understood as the purposeful removal of the item and its placement at another location, for example in a packing box. To...
