摘要:
The invention relates to a vacuum gripping apparatus for moving roll-like loads, the loads being piled on top of each other and resting on their even end faces, the vacuum gripping apparatus comprising a suction plate (3) to be arranged against the end face of a load, the outer circumference (12) of the suction plate being provided with corner portions (19), side edges (21) that connect the corners of the portions being curved inward, and that the outer circumference (12) of the suction plate (3) determines the maximum lateral dimensions of the structure above the suction plate.

La ventouse en matière souple pour appareil de préhension d'objets par dépression, comprend un embout axial tubulaire (3). Dans l'embout tubulaire (3) est engagé de façon amovible l'extrémité tubulaire (4) d'un raccord (5) en matière rigide, cette extrémité tubulaire (4) étant limitée par un épaulement annulaire (6) venant en appui contre le bord (3a) de l'embout tubulaire (3), cet épaulement (6) étant adjacent à une partie annulaire filetée (7) vissée dans un taraudage (8) ménagé sur la surface interne d'une bague (9) entourant l'embout tubulaire (3) de la ventouse et en prise avec cet embout (3). Utilisation pour améliorer la fixation des ventouses à un appareil de préhension d'objets par dépression.
摘要:
Bei einer Sauggreifvorrichtung zum Anheben und Halten von Werkstücken ist die Ventilkammer (4) eines mit einem gummielastischen Saugnapf (1) kombinierten Sicherheitsventils mit einem Faltenbalg (2) ausgebildet, der in der Schließstellung des Ventilstückes (9) entgegen dem auf den Faltenbalg (2) von außen einwirkenden Umgebungsdruck durch eine mit dem Ventilstück (9) gemeinsame Ventilfeder (12) vorgespannt wird, wobei der Ventilsitz (13) für das Ventilstück (9) eine Ausbildung an der Anschlußmündung der Saugluftleitung an die Ventilkammer (4) für eine mit der Ventilfeder (12) gleichsinnige Druckbeaufschlagung des Ventilstückes (9) mit dem über die Saugluftleitung angelieferten Saugdruck aufweist.
摘要:
A pneumatic valve mechanism, especially for controlling the movement of paper, comprises a mouthpiece (47) which defines an air intake (58), a bellows (10) coupled to the mouthpiece, a passage (42, 44) connecting the interior of the bellows to a pump so that when the bellows is not fully retracted suction is created at the air intake (58), and a seal (50) between the mouthpiece and a valve body (14) which is effective when the bellows is fully retracted, following closure of the air intake by a sheet of paper (60), to seal the air intake from the suction pump. Venting air can enter the mouthpiece in the retracted position of the bellows, to permit the sheet to drop off the intake, but without breaking the seal (50), whereby the bellows is maintained in its retracted position. The bellows (10) will only extend again to seek the next sheet when the effect created by the suction pump is interrupted, as by breaking the seal (50) by energising a solenoid (64) and displacing a mechanical linkage (62, 54).
摘要:
The invention relates to a gripping or clamping device (10; 40) for holding articles (12) in place, comprising a base (14) which has a receiving surface (18) that faces an article (12) for holding it in place, the base (14) having at least one passage guide (20) that leads to a passage opening (22) in the receiving surface (18). According to the invention, the receiving surface (18) has at least one nanostructure portion (26, 28) on which a plurality of nanostructure elements are arranged. The invention further relates to a method for handling articles (12).
摘要:
A material handling system includes a body including a first member and a second member. The first member and the second member define a hollow cavity within the body, and a gap disposed between the first member and the second member. The body is in flow communication with a first gas source to provide pressurized gas flow through the gap to generate a lifting force on an object placed adjacent to the body. The body has channels disposed within a central region of the body in flow communication with a second gas source. The channels are arranged to controllably disengage the object from the body.
