Definitions
- the invention relates to a device for temporarily storing continuously fed, extruded, windable plastic pipes according to the preamble of claim 1.
- plastic hoses are to be understood equally. This Plastic pipes are not rigid in themselves, but flexible, so that they are wound up can.
- Plastic pipes are extruded in a continuous process. At the end of the extrusion lines a winder is usually available for thermoplastic pipes of this type a drum that produces tube bundles. These bundles of pipes will be finished of the winding process with plastic or steel straps and can then be removed become. A new winding process then begins.
- JP 01 236 173 A is one Device for temporarily storing a flexible, elongated material at the beginning specified type disclosed.
- a housing Drum arranged, which rotates parallel to the drum axis on its outer surface Has roles. Concentric to the drum axis are at a distance from the rollers other roles that define a cylinder inner jacket.
- the housing has pull-off rollers in the outlet area of the material.
- the cached Material is drawn into the space between the rollers using the rollers, the material being guided along the inner surface of the outer rollers is.
- the material then makes a U-shaped bend and then comes after it opposite direction guide on the rollers of the inner drum to the system to then pull off the material using the rollers. Unless more material of the intermediate storage device is fed as it is discharged via the rollers, moves the U-shaped bend along the interior space between the rollers.
- FR-A-2 676 721 describes a device for storing and unwinding an elongated, flexible body discloses, for example the flexible supply of a soldering head.
- a fixed container is provided for this purpose.
- This has a helical shape Wall, with adjacent wall sections an intermediate space between define oneself.
- the hose starts from a fixed position from the bottom Intermediate space supplied and discharged again along the helix above.
- the hose lies against the outer surface of the container. This way the hose be pulled off, the hose inside the container moving from turn to turn abuts the inner surface of the container.
- the invention has for its object to provide an improved device for the intermediate storage of continuously fed, extruded, windable plastic pipes of the type mentioned, in particular a perfect course of the plastic pipe in the intermediate storage device is to be ensured.
- the invention System thus ensures a simpler manufacturing and storage process for windable plastic pipes and the intermediate binding.
- the cache device has a drum around which the plastic tube is wound is. The basic idea is, in the basic position, the extruded plastic tube in several Windings tightly to make the drum spiral or spiral. Basically it is of course also conceivable to turn the plastic tube around with just a single turn Drum, but then the storage capacity is relatively small.
- the limiting elements of the further development according to claim 3 are preferably according to claim 4 around rods, in particular around freely rotatable rollers.
- This Rollers attached to the outside diameter prevent the pipe spiral from the storage space comes out. By freely rotating the rollers, the overall friction is reduced.
- transverse means that the Extend the rollers transversely to the path of the plastic pipe.
- the system for the production and storage of windable plastic pipes has as middle plant part on a buffer device 1.
- a conventional extrusion device 2 for continuous production i.e. Extruding plastic pipes 3.
- the intermediate storage device 1 has a frame 5. There is a drum in this frame 6 rotatably arranged by means of a motor 7. The surface of the drum 6 has freely rotatable rollers 8 parallel to the axis of rotation.
- the plastic tube 3 produced in the extrusion device 2 first becomes the intermediate storage device 1 fed.
- the plastic tube 3 with several turns around the drum 6 helically between the guide rakes 10 with the bars 11 passed through.
- the plastic tube 3 is made from this intermediate storage device 1 led out and the winding device 4 fed.
- the drum 6 is driven by the motor 7, and the plastic tube 3 lies with its helical turns close to the rollers 8 of the drum 6.
- stage a being the inner initial turn represents stage b an intermediate stage and stage c finally a stage, in which the plastic tube 3 partially abuts the rollers 9 of the frame 5.
- This one Rollers 9 are freely rotatable, the friction is reduced.
- the storage volume is, for example, 25 m. this makes possible it, the winding device 4 at 10 m / min extrusion speed for about 2.5 min to stop without having to interrupt the extrusion process.
