Pin Sorter

Task:
The machine is used for filling magazine tubes with pins for the assembly of cylinder locks.

The flexible opto-electronic system offers the possibility not only to feed parts, but also to check them for type, length, and shape. It is possible to feed further and similar parts, as the system offered is a so-called "open" system, meaning no special guides are needed for correct orientation. The camera belt is also open on one side and therefore insensitive to so-called "jams." Furthermore, the computer offers the possibility to save additional parts.

Resolution:
- detectable differences in height (vertical), corresponds to the Ø/height of the part: from 0.05 mm
- detectable differences in length (horizontal), corresponds to the length of the part, depending on the feed speed of the camera belt: from 0.20 mm

Performance:
- 100–200 parts per minute, depending on type. Partially even faster.

2. Solution Approach

The bulk parts are manually fed into the electromagnetically driven vibratory bowl feeder; from there, they are fed to the outlet.

By means of a controlled conveyor belt, the parts are individually guided past the line scan camera and checked for position and identical part.

Incorrectly oriented parts are blown back into the bowl via valve 1.

N.i.O. (non-compliant) parts are blown out separately into a container via valve 2.

i.O. (compliant) parts are transported to the end of the belt and pneumatically assisted into the customer-provided tube (or see also option: tubes) and vibrated into place.

3. Technical Limitations

• The parts must be clean and oil-free.
• The parts must not hook, stick together, or form chains.
• Important: The required compressed air pressure is 6 bar.
• The offered device complies with the safety and accident prevention regulations for machine tools.

4. Scope of Delivery

• 1 × Al mounting profiles.
• 1 × AFAG vibratory bowl feeder drive, clockwise rotation.
• 1 × Vibratory bowl feeder pot approx. 400 with pre-sorting guide, adjustable height and width deflectors, and full coating with 2 mm polyurethane. Change parts may be required for the 3 different diameters.
• 1 x Camera belt, length approx. 460 mm, width 20 mm, with integrated CCD line scan camera and illumination unit, blow-back nozzle, rejection nozzle, and rejection channel.
• 1 Sensor box for distinguishing whether pins are brass or steel. This requires 2 sensors (material sensor and light scanner). Integration into the Checkbox software for a clean blow-off pulse for "incorrectly" detected parts.
• 1 x Outlet piece at the end of the belt, pneumatically assisted.
• 1 x Accumulation sensor with accumulation program for automatic control of the sorting device (including holder, light barrier, etc.).
• 1 x Festo Check Box with frontend display 4" CDPX-X-A-W-4. Parameterization is done with a laptop to be provided by the customer or the aforementioned frontend display.
• 1 x Control unit for vibratory bowl feeder Reo Vib.
• 1 x Vibratory bowl feeder with mounting plate and clamping for hose reels, control unit for vibratory bowl feeder.
• 1 x Sturdy table with drawer for housing the aforementioned devices.
• 1 x 3-color signal light.
