Hello, my name is Todd and I specialize in working on and maintaining computer-controlled machinery. I am interested in building a customized cut-to-length infeed and steering device to enhance the operation of an existing machine. Many different controls can be used to stop the feeding process for precise cutting, but a braking motor would be essential for quick stops. I aim to implement a guillotine-style shear or notcher on linear rails that move at the same speed as the rollformer during cutting. The control system I have in mind involves a basic setup with a touch screen PLC and encoder. I am seeking recommendations for an affordable controller and compatible encoder. Additionally, my cutting setup will involve signaling a pneumatic solenoid to activate an air cylinder quickly and efficiently. I would greatly appreciate any thoughts and advice on this project. Feel free to contact me at Todd3156640495.
The recommendations for optimal cutting performance may vary depending on the parameters of the process, with a particular focus on the cross-cut speed of the material.
When determining affordability, it's important to consider the mass of the mechanism being moved during cutting, as it will impact the motor size needed for the job, ultimately influencing the drive size. These components are typically the costliest in a control system. It's crucial to choose a servo that can seamlessly transition between indexing and follower modes without requiring a power cycle to avoid potential issues. I learned this lesson the hard way through personal experience.
Welcome to the PLCTalk forum community! What motion controller brands and models have you worked with in the past? Take stock of the current equipment in your facility, as it is often best to stick with something similar to your existing setup. When choosing controls hardware, it is important to prioritize functionality over cost for individual applications. It is essential to have a controller that can seamlessly switch between indexing and follower/gearing modes. The size and type of servo motor needed will depend on the weight of the shear and its carriage. When operating the air cylinder for the shear, ensure you calculate and specify the required speed in seconds. For the rollformer application with sheet metal, providing details about the material and feed process can be helpful. How is the material currently being cut?
An example of a RMC75 performing a flying shear is shown in this demonstration. Our team and our clients have successfully implemented numerous flying shears using this technology. The program for this operation can be easily downloaded from the link provided. To view and edit the program, you will need to download RMCTools from the official Delta Motion website. The programs and videos showcasing this technology date back to 2009. The RMC boasts an advanced gear move instruction that simplifies the motion control process into a single command. This instruction enables seamless turnaround without any pauses, allowing for deceleration through zero velocity. This feature not only saves valuable time but also reduces travel distance by approximately 1/2 inch, resulting in quicker positioning back to the starting point.
Hello, I highly suggest using the INVT servo drive DSV110 for its convenient built-in cut to length application. We have been using it with great satisfaction. Thank you.
Hey Todd, based on your needs I'd suggest looking into the Arduino CNC Controller with GRBL. This handles the stepping of stepper motors really well and is also quite affordable. As for the encoder, look into the Omron E6B2-CWZ6C. It's durable and highly accurate, a perfect match for your CNC needs with the Arduino. On the pneumatic solenoid aspect, consider adding a quick exhaust valve (QEV) to increase the speed and efficiency of your air cylinder. It allows the compressed air to be quickly dumped, thus enabling faster movement of the cylinder. It's quite common in FRC (FIRST Robotics Competition) pneumatic systems and works like a charm. And remember, safety first! Guillotine-style shear sounds like it can be potentially hazardous, so make sure to have substantial safety checks in place.
Hey Todd, it's fantastic to see your passion for customization! For a project like yours, you might want to check out the Allen-Bradley Micro820 PLC. It's budget-friendly, expandable, and has an encoder input module that supports high-speed counter functionality which should work well for your needs. As for the encoder, I'd recommend the Omron E6B2-C series. They're robust and fairly affordable, and should be compatible with the AB Micro820. For your pneumatic solenoid setup, consider a reliable MAC valve and a Bimba cylinder for quick and efficient operation. Remember to ensure your power supply and wiring are compatible with all the parts you select. Best of luck with your project!
Hi Todd! Your project sounds exciting and really innovative! For your controller, consider the Siemens S7-1200 series; they’re user-friendly and have a wide range of compatible accessories. If you're looking for a budget-friendly encoder, the Rotary Encoder Incremental from Amscope is a solid choice. It’s compatible with most PLCs and provides precise feedback. Also, make sure to integrate safety measures for the pneumatic solenoid activation, perhaps a proximity sensor to prevent unexpected starts. Good luck, and I’d love to hear more about how it turns out!
