Definitions
- the invention relates to a preheating structure for a linear filler, in which packs in at least two parallel longitudinal rows intermittently under different processing stations for Preheating, sterilizing and filling are movable, with facilities in the preheating structure to generate heated compressed air, pipelines and at least two with the pipelines connected hot air nozzles are provided such that the surfaces of the packs with Warm air can be supplied.
- packs are used especially for liquid foods Packaged goods sterilized.
- packs are often sold in large numbers per unit of time manufactured, sterilized and filled.
- the packs are continuous, for example conveyed by a round filler or intermittently, for example by means of a linear filler.
- Such linear fillers similar to the type mentioned at the outset are known.
- the entire package is preheated to at least 60 ° C to avoid the disadvantageous process
- the packs can be heated by receiving a pack Carrier which itself has heating devices which heats packages. Alternatively, there are procedures where hot gases, such as hot air, are blown into the package before sterilization become.
- DE-A-2 839 543, or DE-A-1 99 45 500 describe further examples.
- the object of the invention is to improve the preheating structure for a linear filler in such a way that that even when using smaller amounts of sterilizing agent, an effective and sufficient Sterilization with more uniform treatment of the packs takes place and the environment is less polluted becomes.
- This object is achieved according to the invention by improving the swirl and distribution of the hot air upstream of the nozzles connected to at least two nozzles Distribution box is provided, in which a feed pipe opens, the flow cross section is taken up by a swirl disk.
- the measures according to the invention therefore make it possible to reproducibly and exactly the same Bring a lot of warm air to the surfaces of the respective packs and apply them very precisely preheat the desired temperature.
- plastic packs are influenced to different extents and possibly even be changed. With the heating of the usual plastics for packs, For example, polyethylene or PET for plastic bottles, there is a shrinkage, which is small, but can play a role in more precise machining processes. Due to the more precise heating of the packs with the preheating structure according to the invention Shape changes through the shrinkage process reproducible for all packs evenly being held.
- the swirling and distribution of the warm air supplied to the nozzles are further increased by the mentioned swirl disk improved, which extends across the feed pipe and therefore its Flow cross-section occupies more or less.
- the still in the longitudinal direction of the pipeline flowing warm gases are given a swirl by the swirl disk, i.e. a rotational component around the longitudinal direction of the tube with the desired effect of further swirling and good distribution of the warm air and thus the temperature, even before it starts the same in the distribution box.
- the hot air generated is namely from the pipeline the swirl disk is fed into the feed pipe and from there it reaches the distribution box, on which the at least two nozzles are mounted so that the hot air from the distribution box directly in the nozzles are pressed and then led to the respective pack at the outlet end.
- At least two distribution boxes are in the Preheating station installed in a transverse row next to each other, is upstream in front of each feed pipe
- One heating tube each is attached to a heating rod, and a temperature sensor is attached to the supply tube.
- Heating tube is namely installed in the preheating structure according to the invention, whose heating power is controllable. In general it is a temperature increase, which is why this piece of the "heating pipe" pipeline arranged upstream of the feed pipe is called.
- the one arriving before entering the swirl disk and entering the feed tube Warm air sweeps past the heating element in the heating tube and is, depending on that in the end area of the Feed tube measured temperature of the warm air more or less heated additionally.
- a substantially horizontal nozzle carrier plate preferably five distribution boxes with preferably four nozzles each arranged in the transverse row and when all heating pipes are connected to a manifold.
- the generated, low-germ Warm air enters the manifold mentioned, which feeds the heating pipes directly.
- the swirl disk preferably on this Connection point between the downstream end of the heating pipe and the upstream end of the feed pipe is arranged.
- Four hot air nozzles go out from each distribution box. This Nozzles are arranged in pairs next to and behind one another, so two nozzles each in a transverse row and two nozzles are each mounted in a longitudinal row.
- the swirl disk has a circular disk shape with a closed center area, around the slanted blades, the approximately sector-like openings partially seal, are arranged like a wreath. If you face a preferred one Embodiment the heating pipes lying in the vertical direction, then the swirl disk is in arranged in a substantially horizontal plane and the flow is perpendicular. The below Pressurized warm air flows in the direction of the vertical heating pipe and meets the one arranged transversely Swirl disc, whereby the central area is closed and only the warm air can pass through through the wreath-like openings around this central area. For one particularly intensive swirling and thus good distribution of possibly differently heated Partial flows of warm air get a swirl, i.e.
- the swirl disk protrudes at an angle and directs the incoming warm air like a stationary paddle wheel.
- the blades which are each preferably planar, form an angle with the plane of the swirl disk of between 20 and 60 °, preferably 40 °.
- the swirl disk has a circular disk shape because of the cross section of both the heating tube as well as the feed tube is circular. With a different tube shape, the disc can of course, be designed differently accordingly.
- the heating pipes with a bypass pipe for example same diameter are connected, at one end a closable discharge opening is attached and the other end is closed.
- the bypass tube which extends over the area of all heating tubes, approximately parallel to that Distribution pipe runs and preferably downstream with the respective heating pipe at its downstream End is connected.
- One end of this bypass tube is closed or opens the first heating tube, and the opposite end of the bypass tube can be remote controlled Valve are opened such that a blow-out opening for special operating conditions is opened.
- Warm air can be blown out through this bypass pipe until the machine starts again and the warm air is directed through the nozzles into the packs.
- the bypass pipe can also be used to move the package carrier from one treatment station to the next the volume flow with which is blown onto the package carrier will decrease - for example to 10%. This can be done by opening the blow-out opening with the help of a remote-controlled valve. A further reduction in Probability of any particles or product residues on the packaging be entered in the package.
- the invention is advantageously further developed in that the hot air nozzle is a from the floor of the distribution box with the nozzle tube extending closely to the top of the pack has a narrowed outlet.
- the junction box has that in this preferred embodiment Shape of a flat box with four side walls of comparatively low height, the bottom are connected by a floor and above by an upper wall. There is in the top wall a hole with a connection to the feed pipe, so that warm air led out of the feed pipe can flow through this hole in the distribution box.
- each nozzle is tubular with the nozzle tube mentioned, which in connection with the latter via the inlet openings in the bottom of the distribution box stands. Because the inlet opening is in the bottom of the junction box, this extends Nozzle pipe from this floor to the outside of the distribution box towards the one to be blown Pack, usually on top of the pack.
- the Warm air nozzle from the bottom of the junction box to just above the top of the package extending nozzle tube, the downstream end of which is parallel to the conveying direction of the packs extending parallel to the longitudinal rows of the packs at both ends and overlaps open blow channel, the side walls of which inside the nozzle tube Has blowholes.
- the former embodiment with the nozzle tube, the outlet opening has a narrowed outlet to produce a throttling effect for the warm air first embodiment of package, which is open at the top, for example one made of plastic manufactured bottle with bottle neck on top with external thread. The outlet opening then ends a short distance above the top of the bottle neck.
- the last one here described embodiment with the bladder channel applies to the treatment and Pre-heating of blown plastic bottles that are still closed in the upper area.
- EBM exrusion blow molding
- HDPE high-density polyethylene
- each extends from the bottom of the distribution box a nozzle tube, but which has a comparatively larger inner diameter, so is great that with a corresponding recess the bottle neck with the dome still attached can be moved through the nozzle tube.
- the packs or bottles run in a blower duct, which is therefore open at both ends and below, so that the channel shape is only two Sides and above the bottle.
- the nozzles with the downwardly extending ones Nozzle tubes, the nozzle tubes in the second embodiment considered here the blow channel spread.
- the blow channel runs parallel to the direction of the packs, because they are are to be guided with the help of this channel through the downstream end of the nozzle tube become.
- the blower duct also extends parallel to the longitudinal rows of the packs because it Two packs are always conveyed under two nozzle pipes and then for the preheating process stopped.
- the blowing channel runs inside and, so to speak, "through" the nozzle tube, whereby however, the tube and the blowing channel are open at the bottom.
- the side walls of the blow channel have Area of the nozzle tube, i.e. So inside it, blowholes through which the pressurized Warm air present in the nozzle pipe inside the blower duct on the top of the pack or bottle can be inflated.
- the surface of the pack may be provided with warm air.
- the temperature sensor described above gives electrical via appropriate devices Control signals to the heating element in the respective heating tube, so that a desired temperature profile that emerges from the outlet openings of the nozzles or through the blow holes of the nozzle pipes Warm air can be set.
