Definitions

• the invention relates to a device for gripping, lifting, transporting and setting down centrifuge drums, mechanically loadable and emptable centrifuges for de-oiling, dewatering, washing, drying or otherwise treating industrial piece goods, with at least two stations movable trolley which carries a lifting and lowering device, at the extendable end of which a gripping device is arranged which detects the centrifuge drum in the region of its upper edge.
• a device of this type is already known from DE-OS 20 30 591.
• a centrifuge with an extractable centrifuge drum, a loading station and an emptying station are assigned.
• the centrifuge drum is filled with the material to be treated, and in the emptying station the centrifuge drum filled with treated material is placed on a tilting device in which the centrifuge drum can be rotated, for example, by 180 ° that that dealt with
• the device for gripping, lifting and transporting the centrifuge drums thus picks up a drum filled with the material to be treated, places it in the centrifuge, then picks up the empty centrifuge drum located in the emptying station and moves it into the loading station can, until they take up 'the behan ⁇ in the centrifuge drum and punched settle in the emptying station.
• the device according to the invention has the disadvantage that the centrifuge drum can only be emptied in the tilting device located in the emptying station. In practice, however, the desire often arises to empty the centrifuge stream filled with treated material at different points, for example a selective emptying is desired if different industrial general cargo is treated or similar industrial general cargo is treated differently.
• the object of the invention is to avoid the disadvantages of the known device and to create a device which enables centrifuge drums to be emptied at any point on a conveyor line.
• This object is achieved on the basis of the device described at the outset by arranging in a frame connected to the trolley two gripping jaws which are opposite one another and can be pushed radially towards the drum and partially encompass the drum and which are rotatable about a horizontal axis in the Frames are mounted and at least one gripping jaw is provided with a rotary drive.
• the centrifuge drums can be emptied at different points.
• At least one gripping ring that projects outward and encompasses the drum is attached to the centrifuge drum, and the gripping jaws are provided with a groove that serves to receive the gripping ring.
• FIG. 1 shows a side view of a system for centrifuging industrial piece goods with a device according to the invention for gripping, lifting, transporting and setting down centrifuge drums,
• FIG. 2 shows a side view of the device according to the invention with the gripping device lowered
• Fig. 3 is a view along section line III-III in Fig. 2
• Fig. 4 is a view along section line IV-IV in
• FIG. 1 shows a side view of a view for handling, for example galvanizing industrial items with a centrifuge 1, which is assigned a filling station 2 for the centrifuge drums 8, a further treatment station 3 and an emptying station 4.
• a lifting and lowering device 6 which can be moved by means of a trolley 5 guided in rails, has at its lower end a gripping device 7 with which the centrifuge drums 8 on their upper, reinforced edge 9 can be detected .
• the lifting and lowering device has a lifting carriage 25 which is guided on two opposite sides via two rollers 26 in vertical U-rails 27 connected to the trolley 5.
• the gripping device 7 consists of two swiveling hooks which can grip at diametrically opposite locations under the upper reinforcing edge 9 of the centrifuge drums 8.
• the filling station 2 consists, for example, of a turntable 20 which receives two or more centrifuge drums 8 and which can be rotated about the axis 22 by means of a rotary drive 21 and which moves the filled centrifuge drums 8 into a receiving position.
• the movable lifting and lowering device 6 places empty centrifuge drums 8 on this turntable and picks up a centrifugal drum 8 filled with industrial piece goods to be treated and transports it to a centrifuge 1 or 3 and places it there.
• the material to be treated can be de-oiled and / or washed and / or tumbled and / or dried.
• the centrifuge drum 8 can be removed from the centrifuge 1 and fed to a further treatment station 3 or an emptying station 4, via the emptying station 4 the centrifuge Groove drum 8 are rotated 180 ° with the help of gripping jaws 11, 12 rotatable about the horizontal axis 16, so that the drum contents can be fed via a chute 23 to a trolley or conveyor belt (not shown) or the like.
• the gripping jaws 11, 12 are arranged in a frame 10 connected to the trolley 5 and can be advanced radially to the centrifuge drum 8 by means of pneumatic or hydraulic working cylinders 13.
• the gripping jaws 11 and 12 enclose the centrifuge drum 8, so that the gripping device 7 can be opened at the lower end of the lifting and lowering device.
• at least one gripping jaw 12 by means of a drive Wheelan ⁇ be rotated about 180 °, for example 14 to 'auszukippen the drum content.
• At least one gripping ring 15 surrounding the drum 8 is fastened to the centrifuge drum 8, and the gripping jaws 11, 12 have a groove 17 which receives the gripping ring 15.
• the gripping ring 15 and the groove 17 in the gripping jaws 11, 12 ensure that the centrifuge drum 8 is reliably held by the gripping jaws 11, 12 even when only small contact forces are used.
• the rotary drive 14 drives, via a link chain, a sleeve 18 which is rotatably mounted in the frame 10 via rolling elements and in which the shaft 19 of the gripping jaw 12 is non-rotatably but axially displaceably mounted.
• the gripping ring 15 is expediently arranged at the center of gravity on a centrifuge drum 8 filled with material to be treated. Since the height of this center of gravity depends on the type of material to be treated and the filling height, it can be advantageous. be to equip each centrifuge drum with two or three gripping rings 15, which are spaced apart
• O PI are attached in the lower half of the drum.
• the lifting and lowering device 6 is equipped with switches, sensors or the like which release the feed drive of the gripping jaws 11, 12 when there is a gripping ring 15 of the centrifuge drum 8 at the level of the gripping jaws 11, 12.
• the movements of the trolley 5, the lifting and lowering device 6, the gripping device 7 and the gripping jaws 11, 12 can be programmed for various treatment processes.
