Handle in the box

from Wikipedia, the free encyclopedia

As Bin Picking (English 'm picking ) that is robot- based separation chaotic provisioned objects referred.
The first approaches to a solution were developed in the mid-1980s, but reaching into the box has not yet been universally resolved and is therefore still the subject of current applied research.

A typical task for the robot is to transport a workpiece from position A to position B. An example of this is the loading or unloading of processing machines. In practice, it is not sufficient for a large number of applications for the robot to always perform the same movement. Rather, it is necessary for the robot to be able to react to changes, such as a different object position, by using image processing . Due to the availability of a large number of reliable 3D sensors with different principles, more and more researchers are concerned with the analysis of distance data for the solution of the handle in the box. This research, which drives the use of new 3D sensors, is considered to be the future of robot vision.

Alternatives to reaching into the box

  • Dispensing with image processing through orderly delivery (e.g. with shaped pallets) or manual removal by workers
  • Vibrating conveyor for small workpieces
  • mechanical separation by dumping and gripping from the conveyor belt with camera-based evaluation

Motivation for reaching into the box

Although there are alternatives to box picking, many companies are very interested in the further development of existing approaches in order to be able to use box picking in their own production. The main reasons for this are

greater flexibility
The combination of gripping robot and vision system is easier to convert to other parts to be produced than is the case with e.g. B. vibrating tables is possible.
lower costs
Specially manufactured mechanical components have to be redeveloped for each part and are therefore only profitable with large quantities.
Space saving
Due to the significantly lower need for mechanical components.
Noise pollution
Tipping out a box of metal workpieces can be extremely noisy.
Relieve employees
In some industries, for example in the forging area, the ease of work with heavy or unwieldy parts is an important reason for automation - if possible without the detour via a conveyor belt, but directly with the removal from the box.
