What is DP (DigiPeca)? - Basic operation explanation
- level switch on the molding machine signals the demand for material.
- The transport device blower installed next to the molding machine will start up.
- When the blower is started, the pressure inside the transport pipe is reduced.
- The pressure sensor (DP-S) installed on the material supply side detects a constant pressure.
- Upon receiving the detection signal from the pressure sensor, the Digipe controller (DP-C2) outputs a control signal, which operates the cutting device.
Note 1) There are two types of output: "time" and "number of times", either of which can be selected and set.
Note 2) DIGI-PECA can also change the output depending on the length of time Conveying blower is running.
Features
1. Stable material transport over long distances (no signal lines required)
DP is a pressure detection system that uses the change in suction pressure that occurs in the transportation pipe as a transportation signal.
By installing a DP on each device, materials can be transported at a fixed rate without using a signal line, even from a dryer located a long distance away, such as 40 to 50 meters.
This method eliminates the need for electrical wiring work in the transport section, contributing to reducing the effort and cost of installation work.In addition, even if the buildings or processes are far apart, the system can be introduced without electrical work, allowing for flexible response to layout changes and equipment additions.
Furthermore, since materials are less likely to remain in the pipes after transportation is complete, it is also effective in reducing losses when switching materials and preventing the mixing of different materials.
2. Building a flexible transportation system that is not bound by the type of equipment
DP can be connected simply by replacing the hose, so it is easy to build a material transport system even with different types of equipment.It is also possible to build a system that utilizes the standard rotors used in existing equipment.
This pressure detection transport system is suitable not only for new installations but also for expanding or modifying existing transport lines, and can be used in a wide range of molding sites.
It is possible to introduce it even if the equipment manufacturer or cutting machine is different.
