Abstract

Separated containers are automatically transferred from conveying screw(4) to star wheel(5) feeding circular track(6) around which cleaning and polishing stations are located. Cam-actuated holders grip bottles moving round the track and high speed electric motors(8) rotate the bottles. Spray pistols(9) apply coarse and fine polishing material onto containers. Separated containers are automatically transferred from a conveying screw(4) to a star wheel(5) feeding a circular track(6) around which cleaning and polishing stations are located. Cam-actuated holders grip bottles moving round the track and high speed electric motors(8) rotate the bottles. Spray pistols(9) apply coarse and fine polishing material onto containers. Coarse(10), cleaning(11) and fine(12) cloths are pressed against the container exterior and water, cleaning agent and brushes are introduced into the bottle. A star wheel(14) removes processed bottles.

Description

Die in der Getränkeindustrie eingesetzten Kunststoffflaschen (z. B. Polyäthylenterephtalat) sind nach wenigen Umläufen, d. h. etwa nach 6-8 mal Füllen und Waschen außen zerkratzt und abgescheuert und im Inneren möglicherweise noch mit Restablagerungen behaftet, die bei den für Mehrweg üblichen Waschvorgang nicht entfernt wurden. The plastic bottles used in the beverage industry (e.g. polyethylene terephthalate) after a few cycles, d. H. scratched on the outside after about 6-8 times filling and washing and abraded and possibly still inside Residual deposits, which are common with those for reusable Washing process have not been removed.

Restablagerungen können übel riechen und gesundheitsschädlich sein. Die Flaschen können bevor sie neu befüllt werden, auch Flüssigkeiten beinhaltet haben wie Benzin, Reinigungsmittel, Unkrautvernichter, Ameisen-Kill. Verkratzte Flaschen sehen außerdem noch unansehnlich aus. Residual deposits can smell bad and be harmful to health. The bottles can before have to be refilled, including liquids such as Gasoline, cleaning agents, weed killer, ant kill. Scratched bottles also look unsightly.

Die Erfindung betrifft eine Vorrichtung, welche in einen Arbeitsgang die Flaschen außen poliert und innen reinigt und dadurch die Umläufe um ein vielfaches erhöht, bevor die Flaschen dann endgültig ausgesondert werden und das bei einer angestrebten hohen Leistung von über 4000 Flaschen/Stunde. The invention relates to a device which in one The bottles are polished on the outside and cleaned and cleaned on the inside thereby increasing the number of rotations many times before the Bottles are finally discarded and that at a desired high performance of over 4000 bottles / hour.

Die Flaschen werden über Transportbänder einer Einteilschnecke zugeführt, separiert und über ein Sternrad in eine Aufnahmeposition des Rundläufers gebracht. Ein kurvengesteuerter Zentrierstift wird in die Flasche versenkt und drückt diese gegen eine Flaschen-Mitnehmerkupplung, welche von einen schnelllaufenden regelbaren Elektro-Motor (6000-10000 1/min) angetrieben wird. Der Rundläufer hat z. B. über 60 solcher Baugruppen und dreht sich einmal in der Minute um seine Achse. The bottles are one on conveyor belts One-part screw fed, separated and in via a star wheel brought a recording position of the rotary machine. On cam-controlled centering pin is sunk into the bottle and presses it against a bottle driver coupling, which of a high-speed adjustable electric motor (6000-10000 1 / min) is driven. The rotary has z. B. over 60 such assemblies and turns once in the Minute around its axis.

Nach der Übergabe auf den sich kontinuierlich drehenden Rundläufer werden die Flaschen auf die hohe Drehzahl gebracht und mit Poliermittel aus einer Pistole besprüht. Seitlich angeordnete gefederte Segmente mit den Polierstoffen drücken gegen die Flaschen und bewirken den eigentlichen Polier- und Glättvorgang. Um möglichst einen schnellen Glanzeffekt zu erzielen, wird in den ersten zwei Segmenten vorpoliert, dann im dritten gereinigt und im vierten und fünften hochglanzpoliert. After the transfer to the continuously rotating The bottles are spinning on the high speed brought and sprayed with polish from a gun. Laterally arranged spring segments with the Polishing materials press against the bottles and cause them actual polishing and smoothing process. To one if possible To achieve a quick shine effect is the first two Pre-polished segments, then cleaned in the third and in the fourth and fifth mirror polished.

Während des Polierens wird über eine Drehdurchführung und durch eine Bohrung im Zentrierstift Wasser mit Reinigungsmittel unter Druck in die Flasche gespritzt und über eine andere Bohrung wieder abgelassen. Damit wird nicht nur eine massive Reinigung erreicht, sondern auch die Reibwärme, die durch das Polieren entsteht, wird abgeführt. During the polishing process, a rotating union and through a hole in the centering pin with water Detergent injected into the bottle under pressure and over drained another hole. It doesn't just achieved a massive cleaning, but also that Frictional heat generated by polishing is dissipated.

Claims

1. cleaning, smoothing and polishing device for plastic containers, characterized in that
that the device takes the plastic containers from a feed belt ( 1 ) fully automatically, cleans and polishes them fully automatically ( 2 a / b / c / d / e) and then transfers them to a belt ( 3 ) for removal,
that the bottles are separated from a one-piece screw ( 4 ) and transferred to the rotary machine ( 6 ) by a star wheel ( 5 ),
that the bottles are transported through the machine by a rotary machine ( 6 ) with cam-controlled devices ( 7 ) for holding the bottles and high-speed electric motors ( 8 ) for driving the plastic containers,
that the coarse and fine polishing agent is applied to the plastic containers with spray guns ( 9 ),
that segments are provided with coarse ( 10 ), cleaning ( 11 ) and fine cloths ( 12 ) and are pressed against the plastic container with an adjustable pressure,
that water and cleaning agent are fed into and out of the bottle via the rotating unions ( 13 ) and, if necessary, brushes can be introduced to clean the inside wall of the bottles,
and that the bottles are removed from the rotary machine by means of a star wheel ( 14 ).

2. Device according to claim 1, characterized in that the upper part ( 15 ) of the rotary machine is adjustable in height, the one-piece screw ( 4 ), the star wheels ( 5 ) ( 14 ), the bottle driver coupling ( 16 ) are interchangeable and thus the device on the different diameters and bottle heights are adjustable.

3. Device according to claim 1, characterized in that iede bottle is driven by a high-speed, controllable electric motor ( 8 ) (6000-10000 1 / min) and thus produce a cutting speed of 25-30 m / s in order to, for. B. polishing the 100 bottles in a rotary machine at the same time and thus increasing the machine output.

4. The device according to claim 1, characterized in that the bottles are pressurized with a medium (water) so that the pressure of the polishing segments is absorbed can be. The higher the pressure, the better the smoothing of the bottles.

5. The device according to claim 1, characterized in that the polishing segments are attached on 2 sides, so that one is supported and the other double Smoothing and polishing performance can be achieved.

6. The device according to claim 1, characterized in that in the segments 2 a / b pre-polished, 2c coarse polishing pastes removed (cleaned), 2d / e polished and smoothed with fine paste.
