Integral Suction Lifter IHS3025

Compressed air operated with place function

function:

• When the compressed air is switched on, an integrated ejector creates a vacuum
• The piston moves out
• As soon as the suction cup touches the workpiece it holds onto it and the piston immediately returns to its starting position with the workpiece
• As long as the compressed air is switched on the part remains locked in position
• When the compressed air is switched off, an integrated pressure chamber generates a blow-off pulse, causing the piston to move out again and put down the workpiece
• When the pressure chamber is empty, the spring resets and the piston retracts again
• The retracted piston position can be monitored by using a magnetic field sensor (see accessoirs)

course of motions:

1. basic position, compressed air switched off, pistion is retracted, magnetic field sensor is actuated
2. compressed air switched on, piston moves out, workpiece is picked up, piston moves back with picked up workpiece into its starting position 
3. workpiece held and lifted, compressed air is switched on , magnetic field senor is actuated
4. transfer with workpiece
5. compressed air switched off, piston moves out with workpiece,puts down workpiece ad returns to starting position without workpiece
6. basic position, compressed air is switched off, pistion is retracted, magnetic field sensor is actuated

advantages:

• the whole course of motions will only be operating with switching on/off the compressed air
• No additional valve or cylinder necessary
• short cycle times 
• significant cost saving
• no compression of isolated parts
• low tare weight answerable for fast movement
• balance different heights of workpieces
• correct position withdrawel because of non rotating plunger
• the picked up workpiece will be put down automatically
• no problem with long vacuum pipes
• magnetic field sensor for monitoring the picked up workpiece - no uncertain monitoring of the vacuum by using a difficult vacuum switch
• compressed air is switched on + magnetic field sensor is actuated = workpiece will be picked up

use:

• lifting and putting down of workpieces by using "pick and place" function
• simultaneously picking up and lifting of plane workpieces
• seperating paper, plastic bows, inlay, labels,  check cards and other plane workpieces
• irrespective of the piles' height
