、設備の大型化と運転呼量の増大を招く欠点があった。When transferring a single item with a smooth surface, use negative pressure suction with multiple suction cups attached to the underside of a negative pressure box that is connected to an air suction source such as the suction port of a proa and held at negative pressure. A method of suctioning an article with a device is generally adopted, but in such a conventional negative pressure suction device, the outside of the object to be sucked, or
If there is a suction cup in the space between the objects to be sucked, the suction cup will suck in air, which will lower the degree of negative pressure in the hollow of the negative pressure box and reduce the suction power of the object. The air inside the negative pressure box had to be suctioned rapidly using a vacuum cleaner, which had the disadvantage of increasing the size of the equipment and the amount of operation.
本発明はこのような欠点を除去し、被吸着物と対晶しな

体１９によって常閉式の開閉弁Ａが構成されている。On the lower surface of the negative pressure box 1, a large number of cylindrical bodies 6 with open bottom surfaces are arranged at regular intervals. It is fixed, and a screw hole 1 reaching a hollow 7 is provided in the peripheral wall of the central part in the vertical direction.
6 is formed, and the hollow 7 of the cylindrical body 6 communicates with the hollow 2 of the negative pressure box 1 through a vibrator 17 whose both ends are screwed into the screw hole 16 and a screw hole 18 formed on the lower surface of the negative pressure box 1. and
A stepped cylindrical mounting body 11 is screwed onto the male thread 9 at the lower end of the cylindrical body 6 and is licked with a nut 12. The hollow 7 of the cylinder 6 is formed to communicate with the hollow 7, and a rubber suction cup 15 in the shape of a flat plate is fitted on its outer periphery. A valve body 19 with a protruding child 20 is fitted into the valve body 19 so that it can freely slide vertically.
9 is divided into a lower small diameter part 21, a central side diameter part 22, and an upper large diameter part 28 in the length direction, and the spaces between each division are airtightly interrupted by an O-ring 24 that fits tightly into the hollow 7. At the same time, there is a vent hole 27 that passes through the outer periphery of the small diameter portion 21 at the lower end and the outer periphery of the side diameter portion 22 at the center and through the center of the valve body 19.
As shown in the center of the figure, due to the elastic force of the spring 26 attached to the upper end of the hollow 7,
A downward step 25 formed at the lower end of the valve body 19 is abutted against an upward step 18 of the mounting body 11, and the lower end of the contact 20 is maintained in a state protruding below the suction cup 15.
In this state, the large diameter portion 23 of the valve body 19 corresponds to the screw hole 16 of the cylinder body 6 and seals it, so the suction hole 14 and the hollow 2 of the negative pressure box and l are cut off. The cylinder body 6 and the valve body 19 constitute a normally closed on-off valve A.

中空２への大気の流入が阻止されている。When the negative pressure box 1 is lowered by driving the lifting device (not shown), the suction cups 15 are lowered as shown on both sides of the figure.
corresponds to article b on conveyor a, then contact 2
0 is placed on the article, the valve body 19 is relatively pushed up into the cylindrical body 6 against the elasticity of the spring 26, and the suction cup 15 is in close contact with the top surface of the article. The opening/closing valve A opens when the diameter portion 22 corresponds to the screw hole 16, the suction hole 14 communicates with the hollow 2 of the negative pressure box I via the ventilation hole 27 and the vibrator 17, and the inside of the suction cup 15 becomes negative pressure. The goods will be absorbed,
As the negative pressure box 1 rises, the goods are lifted above the conveyor a and transferred to a predetermined position.As shown in the center of the figure, the space between the goods on both sides corresponds to Since the contactor 20 of the suction cup 15 does not come into contact with the article and the valve body 19 is in the lower position, atmospheric air is prevented from flowing into the hollow 2 of the negative pressure box l from the suction hole 14.

効果を奏する。As specifically explained in the above embodiments, the negative pressure adsorption device of the present invention has a suction hole that communicates with the hollow space on the lower surface of the negative pressure box that is connected to an air suction source and whose hollow space is maintained at negative pressure. In a negative pressure adsorption device equipped with a plurality of suction cups formed in the center, a normally closed type is provided with a contact in the suction hole that operates the valve body in one direction with an opening force when it comes into contact with an object to be adsorbed. The gist is that an on-off valve is provided, and the on-off valve is closed unless the contact comes into contact with the object to be attracted.
This prevents the negative pressure inside the negative pressure box from decreasing due to air being sucked in from the suction cup that does not face the object to be attracted, and the object can be strongly attracted even when a relatively small capacity air suction source is used. This has the effect of improving the safety of transport work and reducing operational noise.
