Abstract

Изобретение относитс к межоперационному транспортированию изделий и может быть использовано дл захвата и переноса издели листовой формы. Цель изобретени - расширение функциональных возможностей. Захват содержит цилиндр 2 с подпружиненным поршнем 5 и штоком 6, через которые проходит центральный канал 7, сообщенный с всасывающим патрубком 8. В поршне 5 выполнена полость 9 с размещенным в ней клапаном дл частичного перекрыти центрального канала 7, представл ющим собой диск 11 с центральным отверстием 12. Центральный канал 7 имеет сужение в нижней части на уровне радиального отверсти 16 в штоке 6, что позвол ет ему работать как инжектору. В торце 13 цилиндра 2 имеетс отверстие 14, а элемент дл удержани изделий представл ет собой установленное на торце 13 цилиндра 2 упругое кольцо 15. При закреплении свободного конца штока 6 в руке промышленного робота вакуумный захват может опускатьс при включении вакуума, захватывать изделие и с ним подниматьс , а с перемещением руки промышленного робота на позицию обработки издели опускатьс , укладывать изделие и подниматьс в исходное положение. 4 ил.The invention relates to the interoperational transportation of products and can be used to capture and transfer sheet-shaped products. The purpose of the invention is to expand the functionality. The gripper contains a cylinder 2 with a spring-loaded piston 5 and a rod 6, through which the central channel 7 passes, communicating with the suction nozzle 8. The piston 5 has a cavity 9 with a valve placed in it to partially cut off the central channel 7, which is a disk 11 with a central hole 12. The central channel 7 has a narrowing in the lower part at the level of the radial hole 16 in the rod 6, which allows it to work as an injector. In the end face 13 of cylinder 2 there is an opening 14, and the product holding member is an elastic ring 15 mounted on the end face 13 of cylinder 2. When the free end of the rod 6 is fixed in the arm of an industrial robot, the vacuum pickup can be lowered when the vacuum is turned on, to grab the product and with it to rise, and with the movement of the industrial robot's hand to the position of processing the product, to lower, stack the product and rise to its original position. 4 il.

Claims

Claim

A vacuum grip containing an element for holding products, a cylinder with rodless and rod cavities, a spring-loaded piston with a rod and a central channel passing through them, a suction nozzle and an air compensation element, which is characterized in that in order to expand the functional possibilities, a cavity is made in the piston coaxially to the central channel, and a hole is formed for communicating the cavity in the piston with the rodless cavity of the cylinder and a valve is placed for partial transition of the central channel cover, which is a disk with a central hole, a central hole is made at the end of the cylinder, while the product holding element is an elastic ring mounted on the end of the cylinder, the air compensation element is a radial hole in the rod, the central channel has a narrowing the lower part at the level of the radial hole, and the cross-sectional area of the central hole in the valve disc is equal to the cross-sectional area of the radial hole in the stem and thinner than the cross-sectional area of the Central channel, and the suction pipe is in communication with the Central channel at the free end of the rod.
