Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Further advantages and embodiments are apparent from the appended drawings in the drawings:

(2) FIG. 1 shows an overall representation of a device 1 according to the invention;

(3) FIG. 2 shows a detail of the device shown in FIG. 1;

(4) FIG. 3 shows a representation of the storage device of a device according to the invention;

(5) FIG. 4 shows a partial representation of a device according to the invention;

(6) FIG. 5 shows a detail of the device shown in FIG. 4.

DETAILED DESCRIPTION OF THE INVENTION

(7) FIG. 1 shows an overall representation of a device according to the invention. Here the housing 20 of the storage device 2, in this case more precisely a tipper 2a and a silo 2b, is shown as well as the housing 22, 24, 25, 26, 27 and 28 of the transport devices 3, 4, 5, 6, 7 and 8. The housing device 24 here surrounds a conveyor belt 4. The housing device 22 surrounds an inclined conveyor, which conveys the plastic parisons upwards and specifically in the direction of the said conveyor belt 4. The housing device 26 here surrounds a roller sorter 6. In this case the roller sorter 6 not only sorts the parisons, but also transports them.

(8) In addition, housing devices 25 and 28 are also provided which surround the transport devices 5 and 8, wherein the transport device 8 is an intermediate silo.

(9) FIG. 2 shows a partial view of a device 1 according to the invention for treating and in particular transporting plastic parisons. In this case the reference 2 relates to a storage device in which a plurality of plastic parisons (not shown) are stored. In this case this storage device can for instance have a tipper 2a and a silo 2b. These plastic parisons enter the silo 2b and can be transported from there by means of a transport device 3 which is designed here as an inclined conveyor. The reference 20 designates an enclosure or a housing which completely surrounds the storage device 2, that is to say in this case in particular the tipper 2a and the silo 2b. The reference 34 designates a ventilator device which generates an air stream (arrow P10) inside the housing 20. In order to generate a directional air stream, the housing preferably has an opening to the rear through which the air stream can exit. The reference 36 designates a filter unit, by means of which ambient air is drawn in and in this way is also filtered.

(10) FIG. 3 shows a detail of the device shown in FIG. 1. Here again the ventilator unit 34 is illustrated, and also the filter device 36 which is suitable for drawing in air. The reference 2a designates a tipper which serves for feeding the plastic parisons to the silo 2b.

(11) FIG. 4 shows a further detail of the device according to the invention. It can be seen here that on the rear face of the housing 20 there is a closure device which can close an opening by means of which the plastic parisons can be fed to the housing 20. In this case this closure device can nevertheless leave openings, so that in this way an air stream from the fan 34 to these openings is generated.

(12) FIG. 5 shows a detail of the device shown in FIG. 1. In this connection in particular again the transport device 4 can be seen, which is surrounded by the housing device 24. The reference 52 designates a supply line which serves to supply the system with air. A plurality of branch lines 54 branch off from this supply line 52 and open into specific regions of the devices, such as for example into the housing 22 or also the housing 24. The arrows P1, P2 and P3 show the course of the flow inside the respective housing. The air flows here exit again through openings 58, so that the flow shown by the arrows P1, P2 and P3 is generated overall here.

(13) Likewise the flows P4 and P5 are generated inside the housing 24. Further flows P13, P14 are generated in a housing 25. Here too an opening 58 is again provided, by means of which the air can exit from the housing 25.

(14) The applicant reserves the right to claim all the features disclosed in the application documents as essential to the invention in so far as they are individually or in combination novel over the prior art. Furthermore it is pointed out that features which may be advantageous per se have also been described in the individual drawings. The person skilled in the art recognises immediately that a specific feature described in a drawing may also be advantageous without the incorporation of further features from this drawing. Furthermore the person skilled in the art recognises that advantages may also result from a combination of several features shown in individual drawings or different drawings.
