Winding body, ζ. B. wire, rope and cable bundles or coils made of insulating material are used for protection Covered against corrosion or rotting with liquid surface protection agents, preferably oils.

Up to now it has been customary to transfer the wound bodies to be treated in this way to a containing the liquid protective agent Dip the soaking vessel and drain the excess liquid either over grids or the like to leave or in centrifuges, in which the beverage ίο th winding body are brought to be thrown off. Despite extensive mechanization, both processes require relatively much manual labor, which is also particularly dangerous for accidents and health and is usually associated with a considerable amount of dirt. Drain the excess Liquid requires a large amount of space and time, since, depending on the viscosity of the soaking liquid, takes a few hours to several days. Throwing off the excess Liquid goes faster, but the introduction of the wet, dripping bobbins into the Centrifuges associated with difficulties. In addition, the known centrifuges can only relatively absorb small amounts of wound packages.

In order for a larger number of small-sized structures, in particular of cartridge cases, a To achieve the most uniform possible coating, it is already known to convert the structures into an initially stationary Bring in the centrifuge, fill it with lacquer, remove the lacquer from the centrifuge as quickly as possible to run off and then the excess paint from the painted structures by turning quickly the centrifuge. But also the centrifuges used for this purpose are to accommodate Winding bodies of the type mentioned above are not readily suitable.

The invention is based on the object of creating a device that is particularly advantageous Way is suitable for covering wound bodies with a liquid surface protection agent, the winding bodies also being flooded within an initially stationary centrifuge soaked in the coating liquid and after allowing the liquid to run off by spinning Excess fluid residues are freed.

According to the invention, this object is achieved in that the first as a drinking vessel and then The centrifuge housing serves as a collecting container for the liquid residues thrown off is so suspended on pendulums that it is equipped with a device for covering bobbins with a liquid surface protection agent

its lower part, together with the conveying device and the reservoir for the soaking liquid, located below the working floor level, and that a cylindrical drum instead of a centrifugal drum Carrying body is provided for attaching several superimposed winding bodies, which is designed to be removable from the housing for loading and unloading.

The mass of the centrifuge housing is useful for reducing the vibration amplitudes during Occurrence of imbalances increased by additional masses attached to the housing shell.

By using the centrifuge housing as a drinking and collecting vessel, the dirty one is no longer necessary and uncomfortable work of dipping and placing the dripping coils on drainers or in centrifuges, since the collars are plugged onto and onto the support body in the dry state be introduced into the centrifuge designed according to the invention. All wet work processes can can therefore be carried out in the centrifuge itself.

The special design of the centrifuge ensures a high loading capacity and batch performance achieved, at the same time achieved a space saving compared to the conventional method will.

In the drawing, a centrifuge for impregnating steel wire rings is an exemplary embodiment of the invention depicted with oil.

Part 1 is the base frame embedded in the foundation, on which the Housing 3 of the centrifuge is suspended. In the bearing tube 4 of the housing, the drive shaft 5 is with the

Clutch disc 6 supported. The drive shaft is driven by the flanged electric motor 7. A support body 8 with the wire rings 9 to be treated rests on the clutch disc. The housing is closable in the upper part by a hinged cover 10. A centrifugal pump 11 is set up under him, the intake port 12 of which protrudes into the oil container 13. The pressure port 14 with the compensator 15 opens into the housing 3. The latter is provided with an overflow line 16 which leads into the oil container 13 flows out. 17 is a hydraulic tilting device. To impregnate the wire rings 9, these are on the matching diameter cylindrical support body 8 is attached and this is then by means of a The crane 18 is inserted into the housing 3. After closing the lid 10, the centrifuge is ready for use The pump 11 is now switched on by a program control. This promotes the soaking oil from the container 13 into the housing 3. After the housing is filled, the excess oil runs through the line 16 into the container 13 from. After the planned soaking time has elapsed, the program control switches the pump off. The oil in the housing 3 now flows in the opposite direction through the Pump 11 back into the oil container 13. In the following, by switching on the motor 7, the support body 8 with the wire rings 9 set in rotation. Under the influence of centrifugal force, the excess becomes oil is thrown off, leaving only a thin protective film on the treated wires remains. After the intended de-oiling has been achieved, the centrifuge is switched off and the supporting body 8 lifted out of the housing 3 with the wire rings 9. The centrifuge is thus to receive the ready for the next batch. In order to facilitate the removal of the wire rings 9 from the support body 8, a tilting device is provided 17 is provided, which moves the heavy support body from the vertical to the horizontal pivots.

Claims (2)

Patent claims: 1. Device for covering winding bodies, e.g. wire, rope or cable ties or coils of insulating material, with a liquid surface protection agent, wherein the winding body soaked in an initially stationary centrifuge by flooding with the coating liquid and after draining the Liquid can be freed from excess liquid residues by spinning, characterized in that the first the centrifuge housing (3) serving as a soaking vessel and then as a collecting container for the liquid residues thrown off on pendulums (2) is suspended that it is with its lower part, together with the conveyor (11) and the reservoir (13) for the soaking liquid, below the working floor level is, and that instead of a centrifugal drum, a cylindrical support body (8) for attaching several stacked Winding body (9) is provided, which can be removed from the housing (3) for loading and unloading is trained. 2. Device according to claim 1, characterized in that the mass of the housing (3) to reduce the vibration amplitudes when imbalances occur on the housing shell attached additional mass is increased.
