Abstract

Hitherto known guideway scrapers on machines and equipment, which are preferably made of plastic, use a wedge-shaped lip to scrape the guideways clean of dust, dirt and chips. Because the lip wears, the scraping effect diminishes with time. In addition, the scraping effect occurs only in one direction of the backwards and forwards movement. The subject-matter of the invention employs flexible plastic blades which are matched to the profile of the guideway and, in the course of the backwards and forwards movement, brush the guideway in the manner of a paint brush or windscreen wiper. The advantage consists in that both edges of each blade are used for scraping and bend over elastically counter to the direction of movement, reducing wear. The guideway is cleaned in both directions of movement, that is to say during the outward and the return motion.

Description

FÜHRUNGSBAHNEN - ABSTREIFERGUIDEWAYS - SCRAPERS

Es ist bekannt, Führungsbahnen an Maschinen und Apparaten durch Abstreifer zu schützen. Hierfür werden abriebfeste, keil- oder lippenförmig ausgebildete Kunststoffe verwendet, die mit der Lippe eine Schabewirkung auf der Führungsbahn ausüben, um Schmutz oder Späne von der Führungsbahn zu entfernen. Der Nachteil liegt darin, daß die im Anfang messerartige Lippe nach einer gewissen Laufzeit verschleißt, so daß beim Nachstellen dieser Abstreifer die Abstreifkante immer breiter wird und damit die Lippenwirkung und die Schabewirkung entfällt. Ein großer Nachteil liegt auch darin, daß die Schabewirkung nur nach einer Laufseite der Hin- und Herbewegung ausgenutzt wird.It is known to use guideways on machines and apparatus with scrapers to protect. For this purpose, abrasion-resistant, wedge-shaped or lip-shaped plastics are used used, which exert a scraping effect on the guideway with the lip to To remove dirt or chips from the guideway. The disadvantage is that the lip, which is knife-like at the beginning, wears out after a certain period of time, so that when readjusting this scraper, the scraper edge becomes wider and wider so that the lip effect and the scraping effect are omitted. One major disadvantage lies also in the fact that the scraping effect only after one running side of the to and fro movement is exploited.

Der Gegenstand der Erfindung sieht dem Führungsprofil entsprechend geformte, abriebfest, biegsame Lamellen vor, die so angeordnet sind, daß diese sich zum Zwecke des Abstreifens pinsel- oder scheibenwischerartig beim Hin- und Hergang bewegen können. Der Vorteil liegt einmal darin, daß beide Kanten der Lamellen zum Abstreifen beansprucht werden und andererseits sich die Lamellen entgegen der Bewegungsrichtung umlegen, wodurch der Verschleiß wesentlich herabgesetzt wird.The object of the invention sees the guide profile accordingly shaped, abrasion-resistant, flexible lamellae, which are arranged so that these for the purpose of wiping off like a brush or wiper when walking back and forth can move. The advantage is that both edges of the slats to Stripping are claimed and, on the other hand, the slats are opposite to the direction of movement fold over, which significantly reduces wear and tear.

Die Lamellen werden dem Profil entsprechend in der erforderlichen Stärke hergestellt und zu einem Paket zusammengefaßt.The slats are made according to the profile in the required Starch produced and combined into a package.

Damit ergibt sich - der Anzahl der Lamellen entsprechend -eine Vielzahl von Abstreifkanten. Die Metallteile, die das Paket zusammenhalten, sind in dem Abutreffortere t 4e lltAbwickelt, daß die Lamellen bei der Hin- und Herbewegung begrenzt aber nicht an ihrer Pinselwirkung gehindert werden.This results in a large number - corresponding to the number of slats of wiper edges. The metal parts that hold the package together are in the Abutreffortere t 4e lltDevelops that the slats are limited but not in the to and fro movement are prevented from their brush effect.

Ausführungsbeispiele sind stark vergrößert in der Zeichnung dargestellt.Embodiments are shown greatly enlarged in the drawing.

Fig. 1) zeigt bei Hin- und Rückgang die pinselartige Bewegung der Lamellen 1, die durch die abgewinkelten Metallteile 2 zu sammengefaßt sind und die Gleitführungsbahn 3 sauberhalten.Fig. 1) shows the brush-like movement of the back and forth Lamellae 1, which are summarized by the angled metal parts 2 and the Keep sliding guide way 3 clean.

Fig. 2) zeigt die Anordnung des Abstreiferpaketes entsprechend dem Kugellaufprofil 4 einer Wälzkörperführung.Fig. 2) shows the arrangement of the wiper package according to the Ball running profile 4 of a rolling element guide.

Zu Fig. 3) ist eine Lamelle für das Profil gem. Fig. 2) dargestellt.For Fig. 3) a lamella for the profile according to Fig. 2) is shown.
