ADSORPTION UNIT
Document Type and Number:
Japanese Patent JP2015222095
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an adsorption unit for preventing an adsorption unit from being worn out while assuring a degree of freedom in design for its driving operation.SOLUTION: This invention relates an adsorption unit 1 comprising: a seesaw body 10 turned around an axis 12; an adsorption pad 21 disposed at one side of the seesaw body 10 to adsorb an item to be adsorbed by negative pressure; a bellows body 31 holding the axis 12, arranged in a direction opposite to the adsorption pad 21 and extended at the seesaw body 10; a closing plate 32 closing a terminal end of the bellows body 31 and not changing its position in respect to the axis 12 while being independent to the turning of the seesaw body 10; vacuum generator units 22, 33 arranged at the adsorption pad 21 and the base end side of the bellows body 31; and an air tube 13 for feeding compressed air to these units. When the compressed air is fed, the bellows body 31 is shrunk, the adsorption pad 21 is abutted against an item to be adsorbed to start adsorbing operation, and in turn when the feeding of compressed air is stopped, the adsorption pad 21 releases the item to be adsorbed and at the same time the bellows body 31 extends to cause the adsorption pad 21 to be moved away from the item to be adsorbed.
