Sorting Systems I.A.®

Sistema I.A._2bis

After 25 years of experience in automation…

The evolution of the species!

Clever grabbing of elements directly from the container for small and medium different productions, positioned randomly to serve various client needs:

  • Interlocking of machine tools, generic machines
  • Assemblages and testing
  • Presses for moulding
  • Packaging, Palletising
  • Raw elements or semi-finished
  • Etc, according to one’s requirements

The necessity

Taking elements directly from the container to sort and distinguish them automatically. We have developed three types of machines, according to the type of elements.
The client’s choice will depend on:

  1. Dimension and weight of element
  2. Quantity of support faces
  3. Required cycle time

As to dimension, machines are of two types:

  1. Machine of dimensions from 5 to 50 mm, with a cycle time of one piece/second.
  2. Machine with a dimension starting from 50 mm, for cycle time of minimum 5 seconds.

The support faces mean the number of positions an element pulled on a flat surface can take, for instance a diceDadohas 6 possible support faces.

THE STARTING POINT

Feeding various types of elements with the same machine, responding to the continuous automatic feeding need of small or medium production variables in all the productive sectors. Using intelligent machines that program themselves when there are new elements, without the need of skilled technicians.

The solution

GNG has started this experience in different industries such as automotive, food, pharmaceutical and general industries including the plastics sector, realising three types of automatic sorting and orientation.

Sorting system 1. For small objects from 5 to 50mmm, from 2 to 16 support faces with cycle time of 1 piece/second.

Sorting system 2. For round or toroidal elements with direct grabbing from container, elements with faces from 2 to 4, cycle time starting from 6 seconds.

Smistatore_2

Sorting system 3. For complex elements of minimum 50mm, from 2 to 16 support faces, with the possibility of elements that can be fit within each other in the containers, with cycle time from 6 seconds.

Orientation of elements

Once being made single (isolated from ground), the single element is transferred on a conveyor belt. The element is inspected by a digital camera, which transmits all the position and figurative information of the element to an anthropomorphic robot equipped with satellite gripping ® patent IPC G05B19/418.

The gripper of the robot is configured to realise rotations controlled by the taken element, using a 7° 8° 9° additional axis, applied directly on the gripper pickup point, to obtain the default storage location from any initial orientation of the element.

The gripping of the element will therefore be variable: based on the geometry and orientation of the element in its pickup position, (information processed by the algorithm), the software will decide in autonomy which will be the ideal condition for the gripping of the element, referring it automatically to the store location.

The camera software has in its database the information of the element pre-obtained during auto programming. The programming or auto programming of the digital camera will ultimately be the only thing to do to treat each new element.

Auto Programming

The algorithm will perform transactions with a linear logical system.

The operator must intervene only for the indication of the final installing, while the robot will choose in complete autonomy the gripping point, depending on the arrival and the configuration of the element, selecting the fastest way.

The return arrows indicate that the software waits for the operator approval to continue activities.

The time needed for training the operator to become autonomous, fast and reliable, is a few minutes, following the guide conduct.

The auto programming for the new element is performed in 5-15 minutes.

Bin Picking – Automatic grabbing of elements from the container with recognition and reference

Automatic grabbing of elements from the container by interlinking.

For the automatic interlinking of the elements gripped from the container, two solutions have been tested and certified:

1.Direct grabbing from the container via anthropomorphic robot led by 3D Optical system. The robot picks up the items in bulk from the container, deposits them and then reports it as favourite. With this system, the elements cannot have more than 2-4 support faces, recommended system for cylindrical elements. The system will have a cycle time that will depend on the level of complexity of the elements to be picked up and reported, with experience gained for this method it takes from a minimum of 6-50 seconds per element.

2.Grabbing from the container by a portal Pick-up, picking up the elements in bulk depositing them on a conveyor belt. The robot picks up the item from the belt, led by a 2D Optical system (or in cases of entanglement of elements, a 3D system), reported as favourite. With this system it will be possible to pick up and report complex elements from 2 to 16 support faces. The system will have a cycle time that will depend on the level of complexity of the elements to be picked up and reported, according to experience gained of this system it ranges from a minimum of 3-8 seconds for each element, thanks to the patented satellite gripper ®.

Results

THE IDEA OF “BIG LOT” OR “CHEAP LOT” DOES NOT EXIST ANYMORE

With the Sorting System of GNG you can eliminate the idea of “big lot” obtaining a production system that is cheap and flexible, able to produce a huge variety of products, also in very small lots, as required by clients, nowadays.

Set-up operations have been transformed, now they are fast and easy and “everyone” can execute them correctly and rapidly.
