Vacuum suction pad

Abstract

The present invention provides a vacuum suction pad that can reliably and stably adsorb quail, chicken, or duck eggs, regardless of their shape or orientation. [Solution] A vacuum suction pad 10 that adsorbs quail, chicken, or duck eggs E, is formed in a cylindrical shape, and is expandable and contractible along the cylindrical axis 12 direction, comprising: a first contact portion 16 formed as an opening 14 and having a first tapered shape that gradually decreases in diameter toward the intake side; a second contact portion 18 formed on the intake side of the first contact portion 16 and having a second tapered shape that gradually decreases in diameter toward the intake side; and the first contact portion 16 and the second contact portion 1 The device comprises one or more first bellows sections 20 formed between the first contact section 16 and the second contact section 18 and projecting outward, wherein the maximum diameter X1 of the first contact section 16 is formed to be 0.6 to 1.2 times the transverse dimension of the egg E, and the maximum diameter X3 of the second contact section 18 is smaller than the minimum diameter X2 of the first contact section 16 and is formed to be 0.3 to 0.7 times the transverse dimension of the egg E, and the device is required to adsorb the egg E by bringing the first contact section 16 and the second contact section 18 into contact with the egg E.
