Abstract

PCT No. PCT/DE94/01221 Sec. 371 Date Mar. 11, 1996 Sec. 102(e) Date Mar. 11, 1996 PCT Filed Oct. 14, 1994 PCT Pub. No. WO95/11064 PCT Pub. Date Apr. 27, 1995The invention generally relates to a device for cleaning and accelerating objects which are globular. In particular the invention relates to a device for cleaning golf balls with a high throughput of balls. Devices of this kind are mainly used on golf courses for practice operations as for that purpose, on the one hand, a great number of golf balls is used and, on the other hand, the balls get dirty when they touch the soil or have contact with very short grass residues, which result from the cutting of the greens. Especially the dirt sticking between the dimples of the golf balls, which might dry and become hard, leads to an extremely negative influence on the flight properties of the golf balls. In order to guarantee smooth and economic practice operations, a device of this kind must ensure a high degree of cleaning power as well as a high throughput of balls.

Description

Die Erfindung bezieht sich im allgemeinen auf eine Vorrichtung zur Reinigung und Beschleunigung von Gegenständen, die in wesentlichen zylindrisch, quaderförmig, und kugelförmig sind. Insbesondere bezieht sich die Erfindung auf eine Vorrichtung zur Reinigung von Golfbällen, die einen hohen Balldurchsatz gewährleistet.The invention relates generally to a device for Cleaning and speeding up objects that are essential are cylindrical, cuboid, and spherical. In particular relates the invention relates to a device for cleaning golf balls, which ensures a high ball throughput.

Derartige Vorrichtungen werden auf Golfplätzen hauptsächlich im Übungsbetrieb eingesetzt, da hierbei auf der einen Seite mit sehr vielen Golfbällen gespielt wird und die Bälle andererseits sowohl durch den Kontakt mit dem Erdreich als auch durch sehr kurze Grasreste, wie sie beim Schneiden der Greens entstehen, verschmutzen. Insbesondere der Schmutz, der sich in den Noppen der Golfbälle festsetzt und dort unter Umständen festtrocknet, führt zu einer extrem negativen Beeinflußung der Flugeigenschaft der Golfbälle. Um einen reibungslosen und wirtschaftlichen Übungsbetrieb sicherzustellen, muß deshalb für eine derartige Vorrichtung sowohl eine hohe Reinigungsleistung als auch ein hoher Balldurchsatz gewährleistet sein.Such devices are used on golf courses mainly in practice used, because here on one side with a lot of golf balls is played and the balls on the other hand both through contact with the ground as well contaminated by very short grass residues, such as those created when cutting the greens. In particular the dirt that settles in the nubs of the golf balls and under certain circumstances dries there, leads to an extremely negative influence the flight characteristics of the golf balls. To ensure a smooth and economic Ensuring practice operation must therefore both for such a device high cleaning performance and high ball throughput can be guaranteed.

Eine Vorrichtung zur Reinigung von Golfbällen ist beispielsweise aus der US-Patentschrift PS 4 181 996 bekannt. Die bekannte Anordnung weist eine auf einer Walze angebrachte Rundbürste auf. Um die Bürste ist ein Metallband, dessen Flachseite parallel zur Bürstenachse ausgerichtet ist, derart schraubenförmig angeordnet, daß eine Führung der Golfbälle entlang der Bürstenwalze ermöglicht wird. Durch Antrieb der Walze, beispielsweise durch einen Motor, werden die Golfbälle in der Führung entlang der Bürstenwalze getrieben und auf diese Art gereinigt. Der Reinigungsvorgang kann noch dadurch unterstützt werden, daß ein Reinigungsmittel, beispielsweise Wasser, zugeführt wird. A device for cleaning golf balls is known for example from the US patent PS 4 181 996 known. The known arrangement has one on a roller attached round brush. Around the brush is a metal band, the flat side of which is aligned parallel to the brush axis, arranged helically, that the golf balls can be guided along the brush roller. By The golf balls are driven in the roller, for example by a motor Guide driven along the brush roller and cleaned in this way. The cleaning process can be supported by the fact that a cleaning agent, for example water.

Bei der bekannten Anordnung werden in der Regel die durch den Kontakt mit dem Erdreich bedingten Verschmutzungen vollständig beseitigt; es bleiben allerdings oftmals, insbesondere wenn auf einem feuchten Platz gespielt wurde, sehr kurze Grasreste an den Bällen haften.
Außerdem werden durch die schraubenförmige Metallführung der Golfbälle um die Bürstenwalze die mit Kunststoff beschichteten Oberflächen der Bälle stark beansprucht, was zu einer Verkürzung ihrer Lebensdauer führt.In the known arrangement, the dirt caused by contact with the ground is generally completely removed; However, very short grass remains often stick to the balls, especially when playing on a damp court.
In addition, the screw-shaped metal guide of the golf balls around the brush roller places heavy stress on the plastic-coated surfaces of the balls, which leads to a shortening of their service life.

Darüberhinaus ist bei der bekannten Anordnung eine schnelle Rotation der Bürstenwalze erforderlich, um den geforderten Balldurchsatz zu gewährleisten. Dadurch werden die mechanischen Teile der Vorrichtung, insbesondere die Walzenlager, sehr stark beansprucht, was die Verwendung von qualitativ hochwertigen Teilen verlangt und damit sowohl hohe Herstellungskosten als auch hohe Wartungs- bzw. Reperaturkosten zur Folge hat.In addition, there is a rapid rotation of the brush roller in the known arrangement required to ensure the required ball throughput. Thereby the mechanical parts of the device, especially the roller bearings, are very heavily used, which requires the use of high quality parts and thus both high manufacturing costs and high maintenance and repair costs has the consequence.

Zusätzlich muß bei einem derartigen Aufbau zur Reinigung der Vorrichtung, insbesondere zur Reinigung der Bürstenwalze, ein hoher Aufwand betrieben werden.In addition, with such a structure, the device must be cleaned, in particular to clean the brush roller, a lot of effort.

Aufgabe der Erfindung ist es deshalb, eine Vorrichtung der eingangs genannten Art zu schaffen, die eine vollständige Reinigung der Bälle sicherstellt, die die Beanspruchung der kunststoffbeschichteten Oberfläche der Golfbälle beim Reinigen vermindert, sowie einen vergleichsweise einfachen Aufbau aufweist und damit eine Herstellung und eine Wartung mit verringertem Kostenaufwand ermöglicht.The object of the invention is therefore a device of the aforementioned To create a way that ensures a complete cleaning of the balls that the stress the plastic-coated surface of the golf balls when cleaning reduced, and has a comparatively simple structure and thus a Manufacturing and maintenance with reduced costs.

Gelöst wird diese Aufgabe durch die im Kennzeichnungsteil des Anspruchs 1 angegebenen Merkmale.This problem is solved by the specified in the characterizing part of claim 1 Features.

Bevorzugte Ausgestaltungen der Vorrichtung ergeben sich aus den Unteransprüchen.Preferred configurations of the device result from the subclaims.

Erfindungsgemäß ist die Vorrichtung derart ausgebildet, daß die zu reinigenden Gegenstände durch eine Einrichtung zur Vorreinigung und Beschleunigung vorgereinigt werden und auf eine Geschwindigkeit, die ihnen ein vollständiges Durchlaufen eines Bürstenkanals zur Endreinigung ermöglicht, beschleunigt werden.According to the invention, the device is designed such that the objects to be cleaned pre-cleaned by a device for pre-cleaning and acceleration and at a speed that gives them a complete run through a Brush channel for final cleaning allows to be accelerated.

In einer bevorzugten Ausführungsform werden die Gegenstände in einem Rohr mittels Erzeugung eines Unterdrucks durch einen flüssigen oder gasförmigen Strahl (im folgenden wird die hierzu verwendete gasförmige oder flüssige Substanz als Arbeitsmedium bezeichnet), der durch eine düsenförmige Öffnung unter einem kleinen Winkel in das Rohr eintritt, beschleunigt.
Auf diese Weise kann eine fast reibungsfreie Beschleunigung bewirkt werden. Während der Beschleunigung sind deshalb die plastikbeschichteten Oberflächen der Bälle nur einer sehr geringen Beanspruchung ausgesetzt.In a preferred embodiment, the objects in a tube are generated by generating a vacuum by means of a liquid or gaseous jet (hereinafter the gaseous or liquid substance used for this is referred to as the working medium), which enters the tube through a nozzle-shaped opening at a small angle, accelerates.
In this way, an almost frictionless acceleration can be brought about. During acceleration, the plastic-coated surfaces of the balls are therefore exposed to very little stress.

Zusätzlich führt eine derartige Einrichtung zur Vorreinigung und Beschleunigung aufgrund ihrer einfachen Konstruktion zu geringen Kosten sowohl bei ihrer Herstellung als auch bei ihrer Wartung. Darüberhinaus arbeitet diese Einrichtung durch den hohen Durchsatz an Arbeitsmedium im wesentlichen selbstreinigend.In addition, such a device leads to pre-cleaning and acceleration due to their simple construction at low cost both in their manufacture as well as their maintenance. In addition, this facility works through the high throughput of working medium is essentially self-cleaning.

Nachstehend ist die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels im einzelnen beschrieben; es zeigen:

  • Fig.1 eine Schnittansicht eines bevorzugten Ausführungsbeispiels der Erfindung
  • Fig.2 eine Querschnittsansicht des Bürstenkanals des bevorzugten Ausführungsbeispiels aus Fig.1.

  • 1 shows a sectional view of a preferred embodiment of the invention
  • 2 shows a cross-sectional view of the brush channel of the preferred exemplary embodiment from FIG. 1.

    • Wie in Fig.1 dargestellt, weist ein bevorzugtes Ausführungsbeispiel der vorliegenden Erfindung eine Einrichtung 2 zur Vorreinigung und Beschleunigung der zu reinigenden Gegenstände 1 (beispielsweise der verschmutzten Golfbälle) sowie einen Bürstenkanal 3 auf. As shown in Figure 1, a preferred embodiment of the present Invention a device 2 for pre-cleaning and acceleration of the to be cleaned Items 1 (such as the dirty golf balls) and one Brush channel 3 on.

    Die Einrichtung 2 umfasst ein Rohr 4 mit zwei voneinander getrennten Abschnitten 4a zur Beschleunigung bzw. 4b zur weiteren Beschleunigung und Vorreinigung der Gegenstände. Der durch die Trennung entstehende Zwischenraum ist in Form einer ringförmigen Öffnung bzw. ringförmigen Düse 5 ausgebildet.The device 2 comprises a tube 4 with two separate sections 4a for acceleration or 4b for further acceleration and pre-cleaning of the Objects. The space created by the separation is in the form of a annular opening or nozzle 5 is formed.

    Ein Teil des ersten Abschnitts 4a des Rohres 4 ist von einer rohrförmigen Kammer 6 umgeben. Diese Kammer 6 ist weiterhin durch eine rohrförmige Außenwand 6a, sowie durch eine Abschlußwand 6b definiert. Auf der Seite, die der Abschlußwand gegenüberliegt, verjüngt sich die rohrförmige Kammer, wobei die rohrförmige Außenwand 6a in den zweiten Abschnitt 4b des Rohres 4 übergeht.Part of the first section 4a of the tube 4 is from a tubular chamber 6 surrounded. This chamber 6 is further through a tubular outer wall 6a, as well as defined by an end wall 6b. On the side opposite the end wall the tubular chamber tapers, the tubular outer wall 6a merges into the second section 4b of the tube 4.

    In dem bevorzugten Ausführungsbeispiel sind sowohl der erste Abschnitt 4a des Rohres 4 und die Abschlußwand 6b als auch die rohrförmige Wand 6b und der zweite Abschnitt 4b des Rohres 4 integral ausgebildet. Beide Teile sind gemäß Fig.1 an der Abschlußwand 6b und der rohrförmigen Außenwand 6a, beispielsweise durch Außen- und Innengewinde, miteinander verbunden. Um eine dichte Verbindung zwischen beiden Teilen zu gewährleisten, ist gegebenenfalls ein Dichtungsring 8 vorgesehen.In the preferred embodiment, both are the first section 4a of the tube 4 and the end wall 6b as well as the tubular wall 6b and the second Section 4b of the tube 4 integrally formed. Both parts are in accordance with Fig.1 End wall 6b and the tubular outer wall 6a, for example by external and Internal thread, connected to each other. To establish a tight connection between To ensure both parts, a sealing ring 8 is optionally provided.

    Gemäß eines weiteren, in den Zeichnungen nicht dargestellten Ausführungsbeispiels ist darüberhinaus ein Einstellmechanismus, der eine Veränderung der effektiven Fläche der Öffnung 5 ermöglicht, vorgesehen. Als sehr einfache Ausführungsform kann hierfür beispielsweise ein Außengewinde in der rohrförmigen Außenwand 6a und ein Innengewinde der Abschlußwand 6b oder die hierzu äquivalente, umgekehrte Anordnung vorgesehen werden. Die Fläche der Öffnung kann hierbei durch die Einschraubtiefe des Außengewindes in das Innengewinde reguliert werden.According to a further embodiment, not shown in the drawings is also an adjustment mechanism that changes the effective Surface of the opening 5 allows provided. As a very simple embodiment For this purpose, for example, an external thread in the tubular outer wall 6a and an internal thread of the end wall 6b or the equivalent, reverse Arrangement can be provided. The area of the opening can be changed the screwing depth of the external thread into the internal thread can be regulated.

    Zur Minimierung der Herstellungskosten können, insbesondere wenn der Einsatz bestimmter Materialien dies erfordert, beispielsweise wenn die Einrichtung aus Metall gedreht wird, der erste bzw. zweite Abschnitt des Rohres 4a bzw. 4b, die Abschlußwand 6b und die rohrförmige Außenwand 6a der Kammer, sowie der sich verjüngende Abschnitt der rohrförmigen Außenwand 6a jeweils einteilig hergestellt werden und beispielsweise durch Gewinde und/oder Flanschen miteinander verbunden werden.To minimize manufacturing costs, especially when using certain materials require this, for example if the device is made of metal is rotated, the first or second section of the tube 4a or 4b, the end wall 6b and the tubular outer wall 6a of the chamber, as well as the tapered portion of the tubular outer wall 6a each made in one piece are connected to each other and for example by thread and / or flanges will.

    Die Einrichtung 2 kann aus Kunststoff bestehen und kann beispielsweise durch ein Spritzgußverfahren hergestellt sein. Dadurch kann die Einrichtung sehr kostengünstig hergestellt werden.The device 2 can consist of plastic and can for example by an injection molding process. This allows the device to be very inexpensive getting produced.

    Darüberhinaus kann die Einrichtung 2 zur Vorreinigung und Beschleunigung aus anderen Materialien bestehen, insbesondere wenn bestimmten physikalischen bzw. chemischen Eigenschaften des verwendeten Arbeitsmedium Rechnung zu tragen ist. Falls beispielsweise ein säurehaltiges Arbeitsmedium zur Erhöhung der Reinigungswirkung der Vorrichtung verwendet wird, kann die Einrichtung aus säurebeständigem Material, beispielsweise Stahl oder Stahlguß, bestehen.In addition, the device 2 for pre-cleaning and acceleration from others Materials exist, especially if certain physical or chemical Properties of the working medium used must be taken into account. If, for example, an acidic working medium to increase the cleaning effect the device is used, the device can be made of acid-resistant Material, such as steel or cast steel, exist.

    Wenn andererseits auf die Kosten keine Rücksicht genommen werden und die Einrichtung eine extrem lange Lebensdauer haben soll, kann ein Metall oder eine Metallegierung, beispielsweise Messing, Stahl oder Stahlguß, verwendet werden.On the other hand, if the costs are not taken into account and the facility should have an extremely long lifespan, a metal or a metal alloy, for example brass, steel or cast steel can be used.

    Darüberhinaus können auch, insbesondere die mit dem Arbeitsmedium in Kontakt kommenden Teile mit einer Schutzschicht versehen werden, was insbesondere den Materialverschleiß, bedingt durch den hohen Druck mit dem das Arbeitsmedium in die Einrichtung eingebracht wird, vermindert.In addition, in particular those in contact with the working medium coming parts are provided with a protective layer, which in particular the Material wear due to the high pressure with which the working medium in the device is introduced, reduced.

    An dem Ende des zweiten Abschnitts 4b des Rohres schließt sich koaxial ein Bürstenkanal 3 mit einem im wesentlichen kreisförmigen Querschnitt an. Der Kanal umfasst Borsten 10, die auf einem rohrförmigen Träger 9 senkrecht zur Achse des Kanals angebracht sind. Fig.2 zeigt eine vorteilhafte Ausführungsform des Bürstenkanals, bei der der Träger 9 aus zwei Rohrhälften 3a, 3b besteht. At the end of the second section 4b of the tube, a brush channel closes coaxially 3 with a substantially circular cross section. The channel includes Bristles 10 attached to a tubular support 9 perpendicular to the axis of the channel are. 2 shows an advantageous embodiment of the brush channel, at which the carrier 9 consists of two tube halves 3a, 3b.

    Als Alternative zu zwei Rohrhälften 3a, 3b kann der Träger 9 auch durch mehrere, im Querschnitt segmentförmige Längselementen gebildet sein. Beide Ausfürungsformen ermöglichen eine besonders einfache Wartung bzw. Reinigung des Bürstenkanals 3.As an alternative to two tube halves 3a, 3b, the carrier 9 can also be provided by a plurality of Cross-section segment-shaped longitudinal elements can be formed. Both versions enable particularly easy maintenance or cleaning of the brush channel 3.

    Gemäß eines weiteren, in den Figuren nicht gezeigten Ausführungsbeispiel schließen die Borsten mit der Bewegungsrichtung des zu reinigenden Gegenstandes (in Fig.1 durch die Richtung des Pfeils gekennzeichnet) einen spitzen Winkel ein.According to a further embodiment, not shown in the figures, close the bristles with the direction of movement of the object to be cleaned (in Fig.1 indicated by the direction of the arrow).

    Als Material für den Träger 9 können alle aus der Bürstenherstellung bekannten Materialien, wie Metalle, Metallegierungen, Kunststoffe oder Holz, verwendet werden.All materials known from brush production, such as metals, metal alloys, plastics or wood.

    Das Material der Borsten 10 ist derart auf die zu reinigenden Gegenstände abzustimmen, daß sowohl der Verschleiß der Borsten als auch der Verschleiß der zu reinigenden Oberfläche des Gegenstandes minimiert werden. Beispielsweise eignen sich zur Reinigung verschmutzter Golfbällen aus Nylon gefertigte Borsten.The material of the bristles 10 is to be matched to the objects to be cleaned in such a way that both the wear of the bristles and the wear of the cleaning surface of the object can be minimized. For example, are suitable bristles made of nylon for cleaning dirty golf balls.

    Im folgenden wird die Funktionsweise der Vorrichtung unter Bezugnahme auf Fig.1 für einen einzelnen zu reinigenden Gegenstand 1, insbesondere einen verschmutzten Golfball, erläutert.In the following the operation of the device with reference to Fig.1 for a single object 1 to be cleaned, in particular a dirty one Golf ball explained.

    Durch eine über den Pumpenanschluß 7 angeschlossene Pumpe (nicht gezeigt) wird der rohrförmigen Kammer 6 ein flüssiges oder gasförmiges Arbeitsmedium unter Druck zugeführt. Dieses Arbeitsmedium strömt aufgrund der ringförmigen Öffnung 5 der Kammer 6 durch dieselbe.By a pump connected via the pump connection 7 (not shown) the tubular chamber 6 under a liquid or gaseous working medium Pressure supplied. This working medium flows due to the annular opening 5 of the chamber 6 through the same.

    Aus dem Druck, mit dem das Arbeitsmedium zugeführt wird, resultiert insgesamt eine Strömungseschwindigkeit des Arbeitsmediums in der rohrförmigen Kammer 6. Durch die Verjüngung dieser Kammer erhöht sich diese Strömungsgeschwindigkeit und zwar mit der Zunahme der Verjüngung bzw. der Verringerung der vom Arbeitsmedium effektiv durchströmten Fläche. Die größte Strömungsgeschwindigkeit erreicht das Arbeitsmedium demnach in der ringförmigen Öffnung 5.The total pressure results from the pressure with which the working medium is supplied a flow rate of the working medium in the tubular chamber 6. This flow rate increases due to the tapering of this chamber with the increase in the taper or the decrease in the working medium effectively flowed area. The greatest flow rate the working medium accordingly reaches the annular opening 5.

    Eine Erhöhung der Strömungsgeschwindigkeit bewirkt nun ihrerseits nach der Bernoullischen Gleichung eine Veringerung des Drucks bzw. eine Erhöhung des Unterdrucks. Durch Wahl eines relativ großen Verhältnisses zwischen der von dem Arbeitsmedium effektiv durchströmten Fläche in der Kammer 6 und der effektiv durchströmten Fläche in der ringförmigen Öffnung 5 stellt sich somit ein starker Unterdruck im Bereich der ringförmigen Öffnung 5 ein.An increase in the flow velocity now in turn causes the Bernoullian Equation a decrease in pressure or an increase in negative pressure. By choosing a relatively large ratio between that of the Working medium effectively flowed through the area in the chamber 6 and the effective flow area in the annular opening 5 is thus a strong Vacuum in the area of the annular opening 5.

    Durch diesen Unterdruck entwickelt sich im ersten Abschnitt 4a des Rohres 4, an dessen der ringförmigen Öffnung 5 abgewandtem Ende Atmosphärendruck herrscht, ein starker Sog. In diesem Sog wird der zu reinigende Gegenstand 1 schließlich in Richtung der Öffnung nahezu reibungsfrei beschleunigt.This negative pressure develops in the first section 4a of the tube 4 whose end facing away from the annular opening 5 is atmospheric pressure, a strong pull. In this suction, the object 1 to be cleaned is finally in Accelerated towards the opening with almost no friction.

    Wenn der Gegenstand 1 den Bereich der ringförmigen Öffnung 5 passiert, wird er von dem aus der Kammer 6 durch die Öffnung 5 ausströmenden Arbeitsmedium erfasst und dadurch in dem zweiten Abschnitt 4b des Rohres 4 weiter beschleunigt.When the object 1 passes the area of the annular opening 5, it becomes from the working medium flowing out of the chamber 6 through the opening 5 detected and thereby further accelerated in the second section 4b of the tube 4.

    Darüberhinaus wird der Gegenstand 1 durch das ausströmende Arbeitsmedium vorgereinigt. So wird beispielsweise Schmutz, der sich in den Noppen des Golfballs angesammelt hat und dort angetrocknet ist, angelöst und bereits teilweise weggespült.In addition, the object 1 is pre-cleaned by the working medium flowing out. For example, dirt that accumulates in the knobs of the golf ball and has dried there, dissolved and already partially washed away.

    Nachdem der Gegenstand 1 diesen zweiten Abschnitt 4b verlassen hat, tritt er in den Bürstenkanal 3 ein. Durch die Borsten 10, die etwas in den Bewegungsweg des Gegenstands ragen, wird dieser schließlich nachgereinigt. Diese Nachreinigung wird zusätzlich durch das aus der Enrichtung 2 austretende und durch den Bürstenkanal 3 durchströmende Arbeitsmedium verstärkt. Insbesondere wird der am Gegenstand noch anhaftende Schmutz, beispielsweise kurze an den Golfbällen haftende Grasreste, so abgebürstet und darüberhinaus von dem Arbeitsmedium weggespült. After the object 1 has left this second section 4b, it enters the brush channel 3. By the bristles 10 that something in the path of movement Protruding object, it is finally cleaned. This post-cleaning will additionally through the one emerging from the device 2 and through the brush channel 3 flowing through working medium strengthened. In particular, the subject dirt still adhering, for example short grass residues adhering to the golf balls, brushed off and washed away from the working medium.

    Um eine vollständige Reinigung des kugelförmigen Gegenstands sicherzustellen, muß er entweder vor dem Eintritt in die Vorrichtung bereits einen Drehimpuls besitzen oder ihm muß in der Vorrichtung ein Drehimpuls zugeführt werden. Ein anfänglicher Drehimpuls des Gegenstands kann beispielsweise dadurch bewirkt werden, daß der Gegenstand durch ein gebogenes Rohr in die Vorrichtung geführt wird. In der Einrichtung 2 zur Vorreinigung und Beschleunigung kann an den Gegenstand dadurch ein Drehimpuls übertragen werden, daß beispielsweise der Druck des einströmenden Arbeitsmediums in der ringförmigen Öffnung 5 aufgrund einer geeigneten Einrichtung ortsabhängig variiert. Im Bürstenkanal 3 kann an den Gegenstand ein Drehimpuls dadurch übertragen werden, daß einige der Borsten 10 länger als die restlichen Borsten ausgebildet sind.To ensure complete cleaning of the spherical object, must either have an angular momentum before entering the device or an angular momentum must be supplied to it in the device. An initial one Angular momentum of the object can, for example, be brought about by the fact that the Object is guided through a bent tube into the device. In the facility 2 for pre-cleaning and acceleration can thereby to the object an angular momentum are transmitted, for example, the pressure of the inflowing Working medium in the annular opening 5 due to a suitable device varies depending on the location. An angular momentum can be applied to the object in the brush channel 3 are transmitted by making some of the bristles 10 longer than the rest Bristles are formed.

    Damit der Gegenstand aus der Vorrichtung vollständig austreten kann, sind die Abmessungen der Einrichtung zur Beschleunigung derart festzulegen, daß er beim seinem Austritt eine Geschwindigkeit besitzt, die ihm ein vollständiges Durchlaufen des Bürstenkanals ermöglicht.So that the object can emerge completely from the device, the Determine dimensions of the device for acceleration so that he at has a speed at which it exits completely of the brush channel.

    Der Balldurchsatz durch die Vorrichtung ist im wesentlichen durch die Beschleunigungsleistung der Einrichtung 2 bestimmt. Die Beschleunigungsleistung ihrerseits hängt im wesentlichen von dem im Bereich der ringförmigen Öffnung erzeugten Unterdruck ab; je größer der Unterdruck (bzw. je niedriger der Druck) in diesem Bereich ist, umso höher ist die Beschleunigungsleistung.The ball throughput through the device is essentially due to the acceleration performance the device 2 determines. The Acceleration performance in turn depends largely on that in the area of annular opening generated negative pressure; the greater the negative pressure (or lower the pressure) in this area, the higher the acceleration performance.

    Der Unterdruck kann, wie bereits ausgeführt wurde, dadurch erhöht werden, daß die Strömungsgeschwindigkeit des Arbeitsmediums im Bereich der ringförmigen Offnung vergrößert wird. Dies kann durch eine Erhöhung des Durchsatzes des Arbeitsmediums, beispielsweise dadurch, daß eine leistungsfähigere Pumpe verwendet wird, oder durch die Verkleinerung der Öffnung 5 bewirkt werden. The negative pressure can, as already stated, be increased by the fact that the Flow velocity of the working medium in the area of the annular opening is enlarged. This can be done by increasing the throughput of the working medium, for example by using a more powerful pump, or by reducing the opening 5.

    Die Erhöhung des Durchsatzes des Arbeitsmediums führt neben der erhöhten Beschleunigungsleistung auch zu einer Vergrößerung der Reinigungswirkung sowohl im zweiten Abschnitt 4b des Rohres 4 als auch im durchspülten Bürstenkanal 3.The increase in the throughput of the working medium leads to the increased acceleration performance also to increase the cleaning effect both in second section 4b of the tube 4 as well as in the flushed brush channel 3.

    Einer derartigen scheinbar unbegrenzten Steigerung von Balldurchsatz und Reinigungsleistung sind allerdings dadurch Grenzen gesetzt, daß einerseits aus physikalischen Gründen kein Unterdruck, der geringer als der Dampfdruck des verwendeten Arbeitsmediums ist, erzeugt werden kann und, daß andererseits eine derartige Steigerung die Herstellungskosten der Vorrichtung stark in Höhe treibt. Insbesondere führt eine Steigerung der Pumpenleistung zu einer überproportionalen Erhöhung der Herstellungskosten.Such an apparently unlimited increase in ball throughput and cleaning performance however, there are limits to the fact that, on the one hand, physical For reasons of no vacuum that is lower than the vapor pressure of the used Working medium is, can be generated and that on the other hand such an increase drives the manufacturing cost of the device high. Especially an increase in pump performance leads to a disproportionate increase the manufacturing cost.

    Abhängig von der Art der zu reinigenden Gegenstände muß so ein Kompromiß aus Reinigungsleistung, Durchsatz der zu reinigenden Gegenstände und Herstellungskosten gefunden werden.Depending on the type of objects to be cleaned, a compromise must be made Cleaning performance, throughput of the items to be cleaned and manufacturing costs being found.

    Für die Reinigung von Golfbällen ergab sich aus Versuchen ein sehr guter Kompromiß, wenn der rohrförmigen Kammer ein flüssiges Arbeitsmedium unter einem Druck von ungefähr 3-6 bar zugeführt wird.Experiments resulted in a very good compromise for cleaning golf balls, if the tubular chamber has a liquid working medium under it Pressure of about 3-6 bar is supplied.

    Als Arbeitsmedium kann in der Vorrichtung herkömmliches Wasser verwendet werden. Darüberhinaus kann die Reinigungswirkung im zweiten Abschnitt 4b des Rohres 4 durch Zugabe eines Reinigungsmittels erhöht werden.Conventional water can be used as the working medium in the device. In addition, the cleaning effect in the second section 4b of the tube 4 can be increased by adding a cleaning agent.

    Desweiteren können, je nach der Beschaffenheit der zu reinigenden Gegenstände bzw. nach den Anforderungen an die Reinigungsleistung auch Gase bzw. Gasgemische verwendet werden.Furthermore, depending on the nature of the objects to be cleaned or gases or gas mixtures according to the requirements for cleaning performance be used.

    Um außerdem einer übermässigen Belastung der Umwelt entgegenzuwirken, kann bei der erfindungsgemäßen Vorrichtung das Arbeitsmedium aufgefangen und der Vorrichtung wiederholt über die Pumpe zugeführt werden. Damit die Pumpe, die rohrförmige Kammer sowie der Bereich der Öffnung bei dieser Ausführungsform durch das bereits verwendete Arbeitmedium nicht verschmutzt wird, kann eine Filtereinrichtung zur Reinigung des Arbeitsmediums vor der erneuten Zuführung vorgesehen werden.To also counteract an excessive burden on the environment, can in the device according to the invention, the working medium is collected and the Device can be fed repeatedly via the pump. So that the pump that tubular chamber and the area of the opening in this embodiment A filter device can not be contaminated by the working medium already used intended for cleaning the working medium before re-feeding will.

    Durch die erfindungsgemäße Vorreinigung im zweiten Abschnitt 4b des Rohres 4 und die anschließende Endreinigung in dem Bürstenkanal 3 wird insgesamt eine gegenüber dem Stand der Technik erhöhte Reinigungsleistung erzielt. Insbesondere werden durch die Vorrichtung der Erfindung auch die an den Golfbällen anhaftenden Grasreste entfernt.Due to the pre-cleaning according to the invention in the second section 4b of the tube 4 and the subsequent final cleaning in the brush channel 3 becomes one overall the state of the art achieved increased cleaning performance. Especially the device of the invention also adhere to the golf balls Remnants of grass removed.

    Die fast reibungsfreie Beschleunigung des Gegenstandes im ersten Abschnitt 4a des Rohres 4, sowie die Beschleunigung in dem strömenden Arbeitsmedium veringern darüberhinaus die Beanspruchung der mit Plastik beschichteten Oberfläche der zu reinigenden Golfbälle, was im Vergleich zu bekannten Reinigungsvorrichtungen zu einer Verlängerung der Lebensdauer der Golfbälle führt.The almost frictionless acceleration of the object in the first section 4a of the Pipe 4, and reduce the acceleration in the flowing working medium furthermore the stress on the plastic-coated surface of the cleaning golf balls, what compared to known cleaning devices extends the life of the golf balls.

    Die Beschleunigung in der erfindungsgemäßen Einrichtung 2 gewährleistet darüberhinaus außerdem einen Balldurchsatz der dem Durchsatz der Vorrichtungen gemäß dem Stand der Technik entspricht.The acceleration in the device 2 according to the invention also ensures also a ball throughput according to the throughput of the devices corresponds to the state of the art.

    Durch den vergleichsweise einfachen Aufbau der Vorrichtung gegenüber dem Stand der Technik wird schließlich auch ein verringerter Kostenaufwand sowohl bei der Herstellung als auch bei der Wartung der Vorrichtung gewährleistet.Due to the comparatively simple structure of the device compared to the state the technology will eventually also result in a reduced cost of both Production and maintenance of the device guaranteed.
