DP ® Material Supply Support Unit Summary DP is the pressure switch that operates by detecting changes in vacuum pressure making it possible to convey materials without any wiring of signal lines. A new system that sends signals controlled by changes in vacuum pressure.

The system can be easily built under different maker and material-positive unit type if installing DIGI-PECA. Conveyor Material Cut-off Unit Push Gate Material Cut-off Unit Push Gate DIGIPECA DIGIPECA Injection-Molding Machine The signal line is unnecessary. Electrical work is not necessary even if plants are located in distant places. Factory Push Gate DIGIPECKER No materials left in pipe. Factory Push Gate DIGIPECKER Injection-Molding Machine Conveyor Connection Unit Upon using DIGI-PECA (Switch: DP-S. Micro Computer: DP-C) Materials of a constant quantity can be conveyed without any signal cables even when it is distanced 40-50m away from the dryer.(There is no need for electrical wiring.) Upon using a different model, the same system can be continually used by replacing the hoses. A system that uses existing standard loaders can be constructed. Description of Basic Operation The level guage on the injection-molding machines gives the signal for a need of materials. The conveying blower at the side of the molding machine starts up. Conveying Piping The conveying pipe is depressurized. Push Gate Micro Computer of DIGIPECKER (DP-C) The switch (DP-S) of DIGI-PECA at the material side is being turned ON. Injection-Molding Machine The Micro computer (DP-C) of DIGI-PECA turns ON and send signals for push gate and other units to be started up. Note 1: Choose between “time” and “number of times” for output type. Note 2: Output of DIGI-PECA can be altered according to the length of operating hours of the conveying blower.
