The blog explained how to implement AND and OR logic function in electro-pneumatic system.

Overview:

The control circuit of the cutting device used an AND logical function to execute the operation. By connecting the push buttons in series, the AND logic was obtained. The tipping apparatus, on the other hand, uses an OR logic to trigger the cylinder and tip a vat. The push button's parallel connection translates the logic OR function into the electrical control circuit. The solenoid valve connects the pneumatic system to the electrical controller. The electro-pneumatic circuit cannot be realized without the solenoid valve.

This blog explains about interlocking and latching by using the punching device scenario as an example.

Overview:

In the punching device, the procedure requires two sensors to actuate the double-acting cylinder, and if three sensors are triggered at the same time, the cylinder remains retracted. This is the fundamental condition that must be interpreted in an electro-pneumatic circuit. The XOR logic was employed to complete the assignment by utilizing the interlocking and latching mechanisms depicted in the drawings. When three sensors are activated, the interlocking contacts prohibit the cylinder from retracting. When the link sensor is active, latching contacts allow electricity to pass across the solenoid. To achieve the complete extension, the pneumatic circuit was supplemented with a simple pneumatic memory circuit.

This blog explains about controlling multiple actuators and the role of sensors to achieve the correct sequence.

Overview:

To operate numerous actuators, we must employ double solenoid valves that allow us to extend and retract the cylinder as needed. We appropriately allocated the relay contact to its solenoid, resulting in the condition described in blog. The interpretation of the conditional statement is critical in developing the appropriate controller for the given scenario.

This blog elaborates about the interlocking and latching of sensors in the electro-pneumatic control circuit.

Overview:

In this blog, we discussed the interlock and latch in terms of sensor placement in the control circuit. Sensor 1 is intentionally connected to the actuating push button, as illustrated in the image. In a double solenoid, 5/2 way DCV, the interlock mechanism kept port 4 open. This eventually prevents the double-acting cylinder from retracting prematurely.

This blog explains on how to build a simple automated circuit by applying the concept of logical function, latching and interlocking.

Overview:

Process automation necessitated controllers with fully integrated sensors that recognized the position or condition at a given time. In this blog, we build a circuit for an automatic washing system that demonstrates how to set up a simple electro-pneumatic process.


https://peakd.com/hive-163521/@juecoree/electro-pneumatic-basics-automation-with-counter

This blog explains on how to build a simple automated circuit with the process repeats at a specified number of cycles.

Overview:

We built a simple automation circuit using a counter. The fundamental automation circuit in electro-pneumatic is integrated with a counter to repeat a procedure in a certain number of cycles. When the specified number of repetitions is reached, the system is terminated by the counter. In this blog, we will build a circuit for an automatic washing system with a counter to demonstrate how to set up a simple automated process with a set number of repetitions in electro-pneumatic.


https://peakd.com/hive-163521/@juecoree/electro-pneumatic-basics-automating-with-timer

This blog explains on how to build a simple automated circuit with time dependent controls.

Overview:

We built a simple automation circuit using a timer. Delaying a process step in electro-pneumatic is accomplished by incorporating a timer into the basic automation circuit. Once the timer has been reached, the solenoid will no longer be activated. In this blog, we build a circuit for an automatic washing system with a timer that demonstrates how to establish a simple automated process in electro-pneumatic with a delayed reaction or step in between the process.


https://peakd.com/hive-163521/@juecoree/electro-pneumatic-basics-cementing-press-time-dependent-control

This blog explains on how to build a simple time-dependent controller.

electropneumatic-08.gif

Overview:

In electro-pneumatic, we developed a time-dependent control. This blog demonstrated how to keep activation going by using a timer. The relay timer allows the process to finish before restarting it. In this blog, we used the cementing press circuit as an example of an electro-pneumatic time-dependent control implementation.


https://peakd.com/hive-163521/@juecoree/electro-pneumatic-embossing-device-sequencing-multiple-actuators

This blog explains on how to build a sequential controller and discussed on sequence multiple actuators.

electropneumatic-09.gif

Overview:

In response to the description of an embossing device's functionality, we give a circuit. The action of two double-acting cylinders was properly sequenced by the circuit. Cylinder A (holder) keeps the plastic in place while cylinder B (embosser) embosses it. As long as the embosser is not in its original state, the holder clamps the plaster in place. By measuring the position of each cylinder, the sensors enabled the sequencing motion to be achieved.


https://peakd.com/hive-163521/@juecoree/electro-pneumatic-basics-bending-device

This blog explains the mechanism of a bending device and advance sequencing.

electropneumatic-10.gif

Overview:

Three cylinders stretch and retract to bend a metal strip in the circuit. Cylinder A fully extends, causing the sensor to activate the next cylinder. These three cylinders do not extend and retract at the same time. This is due to the fact that we latched the cylinder movement in line with the order of its motion. We cannot achieve the bending procedure if these cylinders all extend and retract at the same time. The bending process can be completed by placing the sensors and relay contacts in the correct order. The configuration of a bending device might vary based on the type of bend required.
