Abstract

The invention relates to vacuum grippers, namely hand-held devices for gripping and carrying piece objects. The aim of the invention is to improve the usability provided by the speed and reliability of the depressurization of the suction cups. In order to depressurize the suction cups, the head 8 is turned counterclockwise, the rotational movement is communicated to the rod, and the elastic element 7 will direct the needles 5 to the suction cups 4, which are sucked off by the suction cups 4 at the place of their contact with the object to be picked and disturb the vacuum in the cavity between the object and the suction cup. The spring 9 returns the rod to its original position until the finger 11 stops in the border of the groove 10 made in the housing 1. The device makes it easier to work with objects, for example, if necessary to place the object in an aggressive environment, and also provides a quick depressurization of the vacuum gripper. 1 3. p.

The invention relates to a vacuum gripper, TJaM, and, in turn, to hand-held devices for

Captured and carrying piece items.

The aim of the invention is to increase

usability.

FIG. 1 shows a manual vacuum gripper, general view; in fig. 2 - the same view from the bottom; in fig. 3 - a head for a vra- 1 prices of a rod with partial cut.

The manual vacuum grip comprises a housing 1 E in the form of a hollow tube, fastened with a gomoschi nut 2 with a strap 3 of the carrier grigsos 4. The device for removing the vacuum in the suction cup is 1 GNLS 5 fixed to the end of the rod 6 located in housing i by means of an elastic element 7, while at the free end of the stem the head 8 is installed to rotate it, the needles 5 are mounted with an angle of more than 90 ° relative to the axis of the housing 1, and the suckers 4 are installed symmetrically relative to the latter.

The vacuum grip rod may be spring-loaded using a spring 9. At the end of the housing 1, a groove 10 may be formed for engagement with a finger II, which may be fixed on the head 8.

I The device works as follows.

; The device is taken by the body 1 and is attached to the object to be gripped. The suction cups 4 lean against the flat surface of the object and forcefully press the air out of the suction cups. Depressurization occurs as follows. Gyulovka 8 is turned counterclockwise. In this case, the rotational movement and the elastic element 7

directs the needles 5 to the suckers 4. The needles 5 pick up the suckers 4 at the place of their contact with the object and break the vacuum in the cavity between the object and the suction cup 4.

Subject otlipaet from suckers. Spring 9 returns the rod b to its original position until it stops finger 11 in the border of the groove 10, made in the housing 1.

The proposed device makes it easier to work with objects, for example, when

the need to place the object in a hostile environment, and also provides a quick depressurization of the vacuum capture.

Claims (2)
