Embodiment Construction

[0033]By positioning one or more open through holes 40 and positioning one or more raised sealing portions 50, one or more pairs of opposing upper and lower side surfaces will be able to be locked in compression. For any given pair of opposing upper and lower surfaces (25; 35, 36; 35), at least one open through hole is required so that the surfaces can be locked in compression. Additionally, for any given pair of opposing upper and lower side surfaces, at least one raised sealing portion is required so that the surfaces can be locked in compression.

[0034] By forming a sealable compartment 45 between the upper outer surface 25 of the lip 20 and the lower outer surface 35 of the bellows 30 opposite thereto in the compressed state of the suction cup 10, as image 3 As shown in , and by providing an open through hole 40 through which the compartment can be evacuated into the inner volume 15, the suction cup can be locked in a compressed state when connected to a vacuum. In an ...

Abstract

The invention relates to a compressible suction cup having an additional vacuum compartment, as well as a lip, and a bellows therefor. A suction cup for engaging and lifting an object is disclosed, comprising a lip, a bellows, and an upper portion sealingly connected to the bellows for connecting an inner volume of the suction cup to a source of vacuum, which cup, in an operative state, is capable of being locked in an at least partly compressed state of the lip and / or bellows. Locking is accomplished by air entrapped in a sealed exterior volume formed between the lip and bellows and / or between one or more segments of the bellows in an operative state being evacuated through one or more through open holes provided in the lip and / or bellows when vacuum is connected to the suction cup. A corresponding lip and a corresponding bellows for use in the suction cup are also disclosed.

Description

technical field [0001] The present invention relates to a suction cup for engaging and lifting an object comprising a lip, a bellows and an upper side portion sealingly connected to the bellows for connecting the inner volume of the suction cup to a vacuum source, the The suction cup can be locked in the at least partially compressed state of the lip and / or the bellows in the working state. Locking is provided by passing air trapped in operation between the lip and the bellows and / or in the sealed external volume formed between one or more segments of the bellows when the vacuum is connected to the suction cup This is accomplished by venting through one or more open through-holes in the lip and / or bellows. The invention also relates respectively to a corresponding lip and a corresponding bellows for the suction cup. Background technique [0002] Suction cups are commonly used in the automation industry to engage and lift various objects by using the reduced pressure in the...
