Abstract
Description
Die Erfindung betrifft Kunststoffborsten für die Waschbürsten von automatischen Autowaschanlagen, die mit sich bewegenden Bürsten arbeiten.The invention relates to plastic bristles for the washing brushes of automatic car washes that are moving with Brushes work.
Kunststoffborsten für Waschbürsten automatischer Waschanlagen, die mit sich bewegenden, im allgemeinen rotierenden Bürsten arbeiten, weisen üblicherweise ein Kreuzprofil auf. Derartige Borsten sind beispielsweise in der DE-Z "Beschädigung von Autolack beim Waschen mit synthetischen Borsten" (Sonderdruck aus ATZ Automobiltechnische Zeitschrift, 71. Jahrgang, Nr. 10/1969) beschrieben. Dieses Kreuzprofil soll dazu führen, daß die Lackoberfläche eines Fahrzeugs beim Waschen in automatischen Autowaschanlagen weniger beansprucht wird.Plastic bristles for washing brushes in automatic washing systems, those with moving, generally rotating brushes work, usually have a cross profile. Such Bristles are for example in DE-Z "damage to car paint when washing with synthetic bristles "(special print ATZ Automobiltechnische Zeitschrift, 71st year, No. 10/1969) described. This cross profile should lead to the paint surface of a vehicle when washing in automatic car washes is less stressed.
Es hat sich jedoch gezeigt, daß insbesondere bei schlecht gewarteten Autowaschanlagen sich in den Profilritzen derartiger Borsten Staub und Schmutzteilchen festsetzen können, die zu einer Lackbeschädigung führen.However, it has been shown that especially in poorly maintained Car washes in the cracks of such bristles Dust and dirt particles that can cause a Lead paint damage.
Einen wesentlichen Beitrag für bessere walzenförmige Waschbürsten lieferte die DE-B 39 36 922, die besondere Querschnitte in einer besonderen Anordnung zur Laufrichtung der Waschbürste zum Gegenstand hatte.A major contribution to better cylindrical washing brushes delivered DE-B 39 36 922, the special cross-sections in a special arrangement for the direction of the washing brush for Had subject.
Aus der DE-A 197 41 899.6 sind Kunststoffborsten für die Waschbürsten von automatischen Autowaschanlagen bekannt, bei denen das üblicherweise verwendete LDPE durch den Polyester PBT ersetzt ist, der noch einen Zusatz von 1 bis 25 % Polyurethan enthalten kann. Dadurch soll der beim Waschen durch LDPE entstandene Grauschleier (Polymerabrieb) verhindert werden.From DE-A 197 41 899.6 there are plastic bristles for the washing brushes known from automatic car washes where the commonly used LDPE is replaced by the polyester PBT is the addition of 1 to 25% polyurethane may contain. This is said to be the result of washing by LDPE Gray fog (polymer abrasion) can be prevented.
Trotz dieser Verbesserungen kommt es in Autowaschanlagen nach wie vor leicht vor, daß der Lack der gewaschenen Fahrzeuge verkratzt wird.Despite these improvements, it does so in car washes still slightly before that the paint of the washed vehicles scratches becomes.
Der Erfindung liegt also die Aufgabe zugrunde, das vorstehend erwähnte Problem zu lösen. Insbesondere soll also die Gefahr des Verkratzens des Autolacks der gewaschenen Fahrzeuge beim Waschen in Autowaschanlagen verringert werden.The invention is therefore based on the object, the above solve the mentioned problem. In particular, the risk of Scratching the car paint of washed vehicles while washing be reduced in car washes.
Diese Aufgabe wird durch Kunststoffborsten für die Waschbürsten von automatischen Autowaschanlagen, die mit sich bewegenden Bürsten arbeiten, dadurch gelöst, daß Borsten verwendet werden, bei denen es sich um Hohlprofilborsten handelt.This task is done by plastic bristles for the washing brushes of automatic car washes that are moving with Brushes work, solved by using bristles, which are hollow profile bristles.
Die erfindungsgemäßen Kunststoffborsten sind also Hohlprofilborsten. Sie haben vorzugsweise einen runden oder ovalen Querschnitt. Vorzugsweise beträgt bei diesen Borsten der Durchmesser, bei ovalem Querschnitt ist dies die Erstreckung in Richtung der längsten Achse, 0,5 bis 5 mm, bevorzugt 0,5 bis 1,5 mm.The plastic bristles according to the invention are therefore hollow profile bristles. They preferably have a round or oval cross section. The diameter of these bristles is preferably in the case of an oval cross section, this is the extension in the direction the longest axis, 0.5 to 5 mm, preferably 0.5 to 1.5 mm.
Derartige Borsten zeigen die folgenden Vorteile:Such bristles have the following advantages:
Zum einen weisen diese Borsten bei gleichem Durchmesser wie die üblicherweise verwendeten Vollprofilborsten (1,0 bis 2,0 mm) weniger Masse auf. Dies bedeutet, daß beim Waschen in der Autowaschanlage die Aufprallenergie der Borsten auf dem Lack geringer ist. Verkratzungen sind weniger wahrscheinlich.On the one hand, these bristles have the same diameter as that commonly used full profile bristles (1.0 to 2.0 mm) less mass on. This means that when washing in the car wash the impact energy of the bristles on the paint is lower is. Scratches are less likely.
Zweitens haben derartige erfindungsgemäße Profilborsten im Vergleich
zu Vollprofilborsten eine ähnliche Steifheit. Eine derartige
Steifheit ist wichtig, weil die meisten Autowaschanlagen
über den Anpreßdruck der Bürste gesteuert werden. Wenn das Elastizitätsmodul
der Kunststoffborsten, d.h. die
Steifheit, also zu niedrig ist, so arbeitet die Steuerung der
Anlage nicht mehr richtig. Der Vorteil der erfindungsgemäßen
Hohlprofilborsten liegt also in der wesentlich geringeren Masse
im Vergleich zum Vollprofil bei ähnlicher Steifheit der Profilborste.Second, such profile bristles according to the invention have a similar stiffness compared to full profile bristles. Such stiffness is important because most car washes are controlled by the brush pressure. If the modulus of elasticity of the plastic bristles, ie the
Stiffness, i.e. too low, the control system no longer works properly. The advantage of the hollow profile bristles according to the invention is therefore the substantially lower mass compared to the full profile with a similar stiffness of the profile bristle.
Des Weiteren verformen sich Hohlprofilborsten beim Aufprall auf die Karosserie elastisch im Unterschied zu Vollprofilborsten. Dies führt im Zusammenspiel mit der geringeren Masse zu weniger Verkratzungen der Autolacke. Furthermore, hollow profile bristles deform on impact the body is elastic in contrast to full profile bristles. In combination with the lower mass, this leads to less Scratches on car paints.
Die erfindungsgemäßen Kunststoffborsten können aus beliebigen üblicherweise verwendeten Materialien, wie LDPE, oder Polyester, insbesondere PBT mit einem Zusatz an 1 bis 25 Gew.-% Polyurethan hergestellt sein.The plastic bristles according to the invention can be made from any commonly used materials, such as LDPE, or polyester, in particular PBT with an addition of 1 to 25 wt .-% polyurethane be made.
Bevorzugte Materialien für die erfindungsgemäßen Kunststoffborsten sind Polyamide oder Polyester, bevorzugterweise Polyamide, die ausgewählt sind aus der Gruppe PA-6, PA-66, PA-610, PA-612. Natürlich können derartige Materialien auch in Kombination miteinander verwendet werden. Weitere bevorzugte Materialien sind Polyester, insbesondere PBT, bevorzugt mit dem bereits erwähnten Zusatz an Polyurethan.Preferred materials for the plastic bristles according to the invention are polyamides or polyesters, preferably polyamides, which are selected from the group PA-6, PA-66, PA-610, PA-612. Of course, such materials can also be used in combination be used. Other preferred materials are Polyester, especially PBT, preferably with that already mentioned Addition of polyurethane.
Die erfindungsgemäßen Kunststoffborsten werden bevorzugt so in der Bürste eingesetzt, daß die Ausrichtung der Borstenbestückung bzw. des Borstensatzes quer zu einer Rotationsrichtung der Bürste gewählt ist.The plastic bristles according to the invention are preferably used in the brush used that the orientation of the bristle assembly or the bristle set transverse to a direction of rotation of the brush is selected.
Die erfindungsgemäßen Hohlprofilborsten können sämtliche Formen aufweisen. Bevorzugt sind jedoch Formen, wie sie in den beigefügten Fig. 1 bis Fig. 8 gezeigt sind, wobei hier lediglich der Einfachheit halber die äußere Umfangslinie des Querschnitts gezeigt ist.The hollow profile bristles according to the invention can be of all shapes exhibit. However, forms as shown in the attached are preferred Fig. 1 to Fig. 8 are shown, here only the For simplicity, the outer circumferential line of the cross section is shown.
