DE1924293C - Suction head for solid bodies - Google Patents

Description

Suction plate suction space and prevents it from being there creates a vacuum when the piston is lifted. The suction space 14 is then through the ventilation valve 19 closed. When the piston 6 is lifted, a weight of the suction S is formed in the suction chamber 14 Hebers corresponding vacuum. The cam 20 is via a linkage 21 with a not shown Connected hand switch, which is arranged in the vicinity of the handle 26 of the suction cup.

The pin 22 leads through a seal arranged in the cylinder base 3 and is by a

Spring 23, which presses on a collar 22 a of the pin, held in its upper end position. In the bore Ta of the piston rod 7, a nose ring 24 is inserted below, which presses the pin 22 downwards when the piston is sawed. Only in this position does the cam 20 slide along the pin when it is turned and can cause the ventilation valve 19 to open. The nose of the nose washer 24 engages in a longitudinal groove 25 of the guide pin 4 and thus prevents rotation of the piston 6 in the cylinder 1 and thus a rotation of the rolling diaphragm 8.

Claims (5)

1 2 cylinders must be flanged on. The drive motor of the patent claims: The additional vacuum pump can be operated by a manual switch or by an end switch that can be actuated by the piston 1. Suction head for solids can be switched on with an off switch. The drive motor of the an additional cylinder vacuum pump sealed against each other is preferably via an electric piston arrangement formed, with a ventilated line connected to a power source, The drive motor switches itself off again automatically, Cylinder with a in the area of its Aufsetz- as soon as a predetermined vacuum errandes in the suction chamber A suction cup with a seal is sufficient or the load is deposited. connected and the piston rod to the connection io on every suction device already in operation a hoist is set up, so that the additional vacuum pump can be turned upside down on request • indicates that the suction chamber (14) will be retrofitted with the customer. she an additional vacuum pump (12) is connected. forms a unit with the drive motor, which the 2. Suction head according to claim 1, characterized in that the height of the suction head is not exceeded. Also draws that the additional vacuum pump (12) at 15 is the price for such, mass-produced the cylinder (1) is flanged on. Devices low. . . 3. suction head: according to claim 1 or 2, characterized in An embodiment of the invention is in the characterized in that the drive motor shown in the drawing and in the following near-additional vacuum pump (12) by a hand-tert. It shows switch can be operated ao F i g. 1 a longitudinal section through a suction head, 4. Suction head according to claim 1 or 2, characterized in that the left half with lowered, the right half that the drive motor with the piston raised, and
Additional vacuum pump (U) can be switched on by a limit switch attached to FIG. 2, the detail II of FIG. 1 in larger piston (6). . is. a ₅ The parts la and \ b of cylinder 1 are with 5. Suction head according to one of claims 1 to 4, provided with flange rings, between which a roller through characterized in that the drive motor membrane 8 einder with an outer thickened edge Additional vacuum pump (12) is tensioned via electrical. The inner thickening of the edge of the roll line «, is connected to a power source. membrane 8 is on the upper edge of piston 6 30 attached. The attachment point is through an annular Covered damping means 9, which has a prevents the piston 6 from hitting the cylinder cover 2. There is a concentric in the cylinder cover Guide bushing 5 used for the piston rod 7 of the KoI-35 bens6. The piston rod 7 is at the top The invention relates to a suction head for a fixed eyelet 11 for attaching the suction head to one Body with one of a crane hook or the like. The cylinder Cylinder-piston arrangement formed, with derdeckel2 also carries a ventilation hood a ventilation valve provided suction chamber, wherein 10, in which a battery operated bell the cylinder is installed with a 40 in the area of its attachment. At the lower part Ib of the cylinder 1, it closes bound and the piston rod for connection to a cylinder bottom 3, in the middle of a Füh lifting mechanism is set up. locking bolt 4 is attached. This protrudes into a with In a known suction head of this type, a guide bushing 5 is provided with a bore Ta of the piston with every second stroke with the cylinder 45 piston rod 7 and therefore leads together with the locked, with a loosening of the suction head from the guide bush S fixed in the cylinder cover 2, the deposited goods is made possible. These suction heads piston rod 7 in cylinder 1 and prevent the advantage that they are attached to each hoist by squeezing the rolling diaphragm 8 sideways. The part 1 b of cylinder 1 is close to the cylinder create the required vacuum itself. So it takes 50 derboden 3 with an inward-facing bar Vacuum storage container or a strengthening ring that is always provided for secure fastening A ready-to-use vacuum pump must be available. the additional vacuum pump shown schematically In another known suction head in cylinder 12 allows. It is connected to a pressure piston by means of a schematic darder piston arrangement, a suction piston is connected to a pressure piston via a piston rod that is positioned and connected to a check valve 13, the line 55 is connected to the Säügraum 14,
which is driven up by a pressure medium and the cylinder 1 has two joints 15 below, which the this creates the vacuum under the suction piston. with a seal 17 provided suction plate 16 tra-Bei A pressure medium must always be in front of this suction head. Below the suction plate 16 is the be at hand. Suction plate suction space 14a, which is connected to suction space 14 When lifting porous goods or when the seal 60 of the cylinder is connected via a line 18. In processing is no longer correct, the lifting time for the line 18 is a ventilation valve 19, which the known suction heads limited. by a spring 19 c in the connecting position According to the object of the invention, a suction suction chamber 14 - suction plate - suction chamber 14 a hall head should be designed so that the lifting time is. When the piston 6 is lowered, the ventilation lifting can also be carried out on goods or, when the valve is no longer on, wall-free seals can be opened by turning the cam disk 20. These open, being supported on a pin 22. In vsbe , through a position connected to the suction chamber, the atmospheric air penetrates through an additional vacuum pump.
