SPT Optim cross cut sawing machine
SPT cross cut saw equipped with a digital pusher with optimization
- The part is placed by the operator on a roller conveyor.
- He marks with a fluorescent pencil the cuts he wishes, in order to eliminate defects.
- The pushing tray equipped with a sensor detects the ends of the part, all the pencil marks and memorizes the lengths between each one.
- This allows, thanks to a calculator with an optimization program, to work in the following way: The length between two marks is compared with a series of previously registered standard lengths, and memorized (cut list). A minimum off cut length is also set and memorized. Of course, these entries are very easily modified.
- The computer calculates, following an algorithm, all the cutting possibilities to obtain standard lengths from the part, by generating as little off cuts as possible. The cross cut saw will thus execute the possible cuts automatically. The non-recoverable off cut, generated by this calculus, will be combined to the off cut due to a defect, in order to avoid any unnecessary cuts.
- The parts and off cuts are evacuated.
- A gap is made between the exit of the cross cut sawing machine and the beginning of the roller conveyor. This implicates that the off cut lengths are compatible with this space.
- At the cross cut saw exit, a mechanized roller conveyor allows the stacking of the parts.
- At the exit of the sawing machine, a label printer is installed, in order to identify the parts afterwards.
