3-position ROBO Cylinder® Controller MEC (Mechanical Engineer Control)

Features

Low Cost The PMEC package, which comes with a controller, power supply, acceleration/speed change function and PC connection cable, among others, is at an affordable price. The MEC PC software can be downloaded free of change from IAI’s website.

Easy OperationEven a beginner can set up the controller without reading the operation manual. The acceleration and speed can be changed using the knobs on the controller.

Push-motion Operation/Intermediate Stopping

Easy Replacement from YourAir-cylinder SystemOperation signals are exactly the same as those used to operate air cylinders. This means that you can use the program of your current PLC directly.

Push-motion operation can be performed in the same manner as you would with any air-cylinder system. Also, you can cause the actuator to stop at any desired intermediate point between the home position and stroke end by changing the setting of the intermediate point using the MEC PC software.

The customer was using an air-cylinder system before, but every time the work part was changed, the stopper position had to be changed to adjust the application position, which was time-consuming given the many varieties of work parts handled. After introducing a ROBO Cylinder + MEC system, setup and position change became easy and operation also became more stable. Another plus is that since air is not used, compressors are no longer necessary, resulting in a simpler system.

This system applies adhesive to mechanical parts using a dispenser. The semi-automatic system has operation switches that are used to move the dispenser to the left and right.

This system drives a facility that cuts medical device parts.

This system cuts a bundle of medical device parts. The customer adopted a ROBO Cylinder to allow for fine-tuning of cutting speeds and ensure stable operation. Since powder dust generates from cutting, the dust-proof RCP2W was selected. Also, the system was designed with a guide to prevent the rod from receiving lateral forces when cutting.

This process is designed to press-fit resin parts into the frames of household appliances.

Before, the operator had to tap each resin part for installation, and this manual process was subject to problems, such as ➀ the part being damaged and ➁ the insertion amount becoming varied, when the part was not tapped properly. After introducing a ROBO Cylinder system, the customer can now perform the process stably, resulting in quality improvement.

This system presses seals in a process where seals, supplied in the form of tape, are attached to work parts.

Before, the operator was pressing seals manually, but the customer considered automating the process to standardize varying results and also to prevent careless mistakes. After considering an air-cylinder system, the customer decided to adopt a ROBO Cylinder system because with an air-cylinder system, varying pressures caused by fluctuation in the main pressure could produce defects.

This is an example of an application where the angle of a dispenser is changed.

A jig is used to covert the linear motion of a ROBO Cylinder rod into rotary motion to change the angle of the applicator dispenser. The speed and range of dispenser movement can be changed with ease, so setup is also easy when the product is changed.

This is a sweets transfer system that pushes out trays on which sweets are placed onto a conveyor.

The customer was using an air-cylinder system before, but because adjusting the push-out speed was difficult, sweets sometimes jumped out of the trays. After introducing a ROBO Cylinder + MEC system, the customer enjoyed the following benefits while continuing to use the controls of the original air-cylinder system (such as wirings and programs) with little changes:➀ Sweets no longer jump out.➁ The tact time became shorter without having to change the approach and return speeds.

This system is used to automatically shape Gohei mochi(note) and put them on skewers. The baking process is manual.

The customer adopted a ROBO Cylinder system for shaping and pressing gohei mochi and piercing them with skewers. The actuator that pierces skewers moves at high speed until immediately before piercing, where it reduces the speed and moves slowly to prevent mochi from deforming. The customer also likes this system because it can be used in locations without an air supply and there is no compressor noise. This system was adopted by stores selling gohei mochi in tourist places, which together manufactured 50,000 pieces of gohei mochi in five days during the festival period.

This system is used to align lunch boxes on a conveyor before they enter a packaging machine.

Lunch boxes flowing on a conveyor are pressed against the guide by the ROBO Cylinder rod to align the boxes before they enter the packaging machine. The customer was using an air-cylinder system before, but adjusting the pressing force was difficult and work parts sometimes got scratched or caught. With the current ROBO Cylinder system, adjustment is easy and quality has also improved.

This system is used to press against a die and bend a copper shaft, which is a part of a household appliance.

Before, the customer was using an air-cylinder system to perform this bending operation. After changing to a ROBO Cylinder + MEC system, low-speed operation is now possible and pressure has also stabilized. The result is elimination of warped or burred work parts and, consequently, stable quality.

Before, the customer was manually inserting nylon rivets in the assembly process, where sometimes rivets were inserted with an excessive force, while other times the insertion force was too small. After adopting a ROBO Cylinder system, the insertion speed and insertion force have become constant and quality has improved.

This device is used to cut lead wires of electronic components.

This system, designed to cut lead wires of electronic components, was operated by an air cylinder before. However, many work parts were scrapped due to cutting problems and frequent replacements of cutting blades kept the maintenance cost high, and eventually the customer adopted a ROBO Cylinder system. With the ROBO Cylinder system, fine-tuning of the speed and acceleration of the cutting blade is now possible and cut surfaces of wires have become cleaner, resulting in a significant reduction in the number of work parts that must be scrapped due to cutting problems. In addition, this system allows for setting of a desired blade stopping position, which has helped prevent tool damage caused by collision with the blade tip.

This mechanism is used for an iron pipe welding system to move a welding torch at a constant speed.

Before, this process was performed by skilled operators, where the quality of welded pipes varied. After adopting a ROBO Cylinder system, the moving speed has become constant and quality has stabilized. Speed change is also very easy and the operator can fine-tune the speed by looking at the condition of the products. The ROBO Cylinder and MEC controller are the only components of this system; hence the low cost and easy operation of the system.

This system is used to slowly move a stirring bar up and down to agitate chemical contained in a flask.

The customer adopted this system as a sample unit for evaluation before building a full-scale system. Initially the customer was planning to use an air cylinder to achieve agitation, but found the ROBO Cylinder system more attractive because it can be operated only with a 100-V power supply and the amplitude and agitation speed can be changed freely.

This system is used to push out parts from a conveyor onto another conveyor.

Before, the customer was manually transferring work parts because their plant had no air supply. Thanks to the ROBO Cylinder and MEC, the process is now automated. Sensor signals are input directly to operate the actuator without a PLC. Since a desired acceleration can be set, work parts are not scratched as they usually are with an air-cylinder system.
