Description

Die Erfindung betrifft eine transportable Strahlgutschleuder mit einem über Rollen laufenden, endlosen Spezialriemen und einer auf ihrer Außenfläche mit einer Profilierten Bandage versehene- drehbaren Scheibe, wobei der Spezialriemen die Bandage teilweise umschlingt und das Strahlgut zwischen den Außenflächen der Bandage und des Spezialriemens beschleunigbar ist.The invention relates to a portable blasting machine with an endless special belt running over rollers and a rotatable disc provided on its outer surface with a profiled bandage, the special belt partially wrapping around the bandage and the blasting material between the outer surfaces of the bandage and the special belt being accelerated.

Aus der DE-B 1 073 345 ist eine Vorrichtung zur Erzeugung eines Strahles von körnigem Gut bekannt, bei der sich ein Band um den teilweisen Umfang der rotierenden Scheibe bewegt. Der Nachteil dieser Vorrichtung ist, daß keine kontinuierliche Schwenkbewegung möglich ist, weil der Strahlmittelzulauf gesondert von Hand aus nachgestellt werden muß, damit das Strahlgut von dem Band und der Scheibe erfaßt wird. Diese Ausführung bewirkt, daß bei ungleichmäßiger Zuteilung von Strahlgut das Band wegen Fehlens einer präzisen Zwangsführung abläuft und keine Mitnahme weiteren Strahlengutes gewährleistet und somit funktionsfähig ist. Diese Ausführung ist ortsfest ausgelegt.From DE-B 1 073 345 a device for generating a jet of granular material is known, in which a belt moves around the partial circumference of the rotating disk. The disadvantage of this device is that a continuous pivoting movement is not possible because the blasting agent feed has to be adjusted separately by hand so that the blasting material is gripped by the belt and the disk. This design has the effect that if the blasting material is not evenly distributed, the strip will run due to the lack of precise positive guidance, and no further blasting material will be taken along and will therefore be functional. This version is designed to be stationary.

Die der Erfindung zugrundeliegende Aufgabe besteht darin, eine Vorrichtung der eingangs genannten Art vorzuschlagen, bei der eine sichere Zwangsführung des Spezialriemens gewährleistet ist, so daß der Spezialriemen während des Betriebes der Strahlgutschleuder nicht von den Rollen gleitet. Ferner soll eine möglichst gezielte Abschleuderung des Strahlgutes durchführbar sein, ohne daß der Spezialriemen seitlich abgleiten kann. Das Nachspannen des Spezialriemens soll auf einfache Weise möglich.The object on which the invention is based is to propose a device of the type mentioned in the introduction, in which a secure positive guidance of the special belt is ensured, so that the special belt does not slide off the rollers during operation of the blasting material centrifuge. Furthermore, it should be possible to spin the blasting material as precisely as possible without the special belt being able to slide sideways. Retensioning the special belt should be possible in a simple manner.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Außenfläche der Bandage Umfangsrillen aufweist und daß die Innenfläche des Spezialriemens mit einer parallel zur Umfangsrichtung verlaufenden Profilierung versehen ist, in die die Außenfläche der den Spezialriemen führenden Rollen mit einem entsprechenden Profil eingreift.This object is achieved in that the outer surface of the bandage has circumferential grooves and that the inner surface of the special belt is provided with a profile running parallel to the circumferential direction, in which the outer surface of the rollers guiding the special belt engages with a corresponding profile.

Sofern die Bandage mit der Scheibe rotiert, wird der die Bandage teilweise umschlingende Spezialriemen von der Bandage kraftschlüssig mitgenommen, wobei das Strahlgut zwischen den Rillen der Bandage und dem Spezialriemen liegt. Durch die Drehung der Bandage mit Scheibe wird das zugeführte Strahlgut erfaßt, beschleunigt und dann tangential abgeschleudert. Der Spezialriemen wird auf seiner Innenfläche über die ineinandergreifenden Profilierungen dieser Innenfläche und der Außenfläche der Rollen zwangsgeführt, wobei der Spezialriemen nicht seitlich von den Rollen gleiten kann. Hierdurch ist gewährleistet, daß auch bei ungleichmäßiger Zuführung des Strahlgutes der Spezialriemen sicher in seiner Position verbleibt. Das Strahlgut wird zwischen den Umfangsrillen der Bandage und der Außenfläche des Spezialriemens beschleunigt. Diese Betriebsweise ähnelt einem Riemenantrieb nur unter anderen Bedingungen.If the bandage rotates with the disk, the special belt partially wrapping around the bandage is frictionally carried along by the bandage, the blasting material lying between the grooves of the bandage and the special belt. By rotating the drum with disc, the blasting material supplied is grasped, accelerated and then thrown off tangentially. The special belt is positively guided on its inner surface via the interlocking profiles of this inner surface and the outer surface of the rollers, the special belt not being able to slide laterally from the rollers. This ensures that the special belt remains securely in its position even when the blasting material is fed unevenly. The blasting material is accelerated between the circumferential grooves of the bandage and the outer surface of the special belt. This mode of operation is similar to a belt drive only under other conditions.

  • Figur 2 den Schnitt A-B gemäß Figur 1 und
  • Figur 3 eine Seitenansicht der erfindungsgemäßen transportablen Strahlgutschleuder im Schnitt mit Exzenterscheibe und Schubstange.
The invention is explained in more detail with reference to the accompanying drawing. Show it :
  • 1 shows a side view of the blasting material centrifuge according to the invention in section:
  • Figure 2 shows the section AB of Figure 1 and
  • Figure 3 is a side view of the portable grist blast according to the invention in section with eccentric disc and push rod.

Gemäß Figuren 1 und 2 wird die Scheibe 2 mit Bandage 3 durch den Elektro-Flanschmotor 1 angetrieben. Die Scheibe 2 ist auf iherer Außenfläche mit der Bandage 3 versehen. Diese Bandage 3 ist mit Förderrillen ausgebildet, welche jeweils mit einem Bund an einer Seite die Oberfläche der Scheibe überlappen und sie ist über Bohrungen mit einer Befestigungsschraube 4 an der Scheibe 2 befestigt. Das Schleudergehäuse 5 dient als Schutz und zur Anbringung weiterer Teile. Der Strahlgutbehälter 6 ist mit dem Gehäuse 5 durch die Laschenverbindung 19 fest verbunden. Das Strahlgut 7 kann nach dem Öffnen des Absperrschiebers 8 mit dem Bedienungshebel 9 (auf/zu) in den beweglichen Schlauch 10 gleiten. Der Schlauch 10 ist insbesondere als Gummischlauch ausgebildet und führt das Strahlgut 7 zu dem Strahlgutzuführungsrohr 11, das auf der Ringscheibe 12 befestigt ist.According to Figures 1 and 2, the disc 2 with bandage 3 is driven by the electric flange motor 1. The disk 2 is provided with the bandage 3 on its outer surface. This bandage 3 is designed with conveyor grooves, which each overlap the surface of the disk with a collar on one side, and is fastened to the disk 2 by means of bores with a fastening screw 4. The centrifuge housing 5 serves as protection and for attaching further parts. The blasting material container 6 is firmly connected to the housing 5 by the tab connection 19. After opening the gate valve 8, the blasting material 7 can slide (open / close) into the movable hose 10 using the operating lever 9. The hose 10 is designed in particular as a rubber hose and guides the blasting material 7 to the blasting material feed pipe 11, which is fastened on the annular disc 12.

Die Ringscheibe 12 ist quergeteilt, dient mit dem Gewindespannbolzen 16 zum Nachspannen des Spezialriemens 15 und trägt das Strahigutzuführungsrohr 11, die beiden Rollen 14 und 26, den Gewindespannbolzen 16 mit Rechts- und Linksgewinde, die beiden Gewindestoppen 17 und den Schwenkhebel 18 und die Schubstange 25. Die Ringscheibenführung 13 ist als Laschenführung ausgebildet. Der endlose Riemen 15 läuft über die beiden Rollen 14 und 26. Die. Rollen 14 und 26 weisen auf ihrer Außenfläche das Profil 29 auf, das in die Profilierung 28 auf der Innenfläche des Spezialriemens 15 eingreift. Diese als Umfangsrillen ausgebildeten Profilierungen verhindern das Abgleiten des Spezialriemens 15 von den Rollen 14 und 26. In dem dargestellten Ausführungsbeispiel verlaufen die Profilierungen 28 und 29 über die gesamte Breite des Spezialriemens 15 bzw. der Rollen 14 und 26. Sie greifen verzahnt ineinander. Ferner ist die Bandage 3 mit Umfangsrillen 27 versehen, die im Querschnitt halbkreisförmig sind. Das Strahlgut 7 befindet sich in diesen Umfangsrillen 27 der Bandage 3 und dem Spezialriemen 15. Der entstehende Strahl 21 trifft das zu strahlende Objekt 20. Der Griff 22 ist an dem Gehäuse 5 befestigt.The washer 12 is cross-divided, is used with the threaded clamping bolt 16 for retensioning the special belt 15 and carries the beam feed tube 11, the two rollers 14 and 26, the threaded clamping bolt 16 with right and left hand threads, the two threaded stops 17 and the pivot lever 18 and the push rod 25 The ring disk guide 13 is designed as a tab guide. The endless belt 15 runs over the two rollers 14 and 26. Die. Rollers 14 and 26 have on their outer surface the profile 29 which engages in the profile 28 on the inner surface of the special belt 15. These profiling formed as circumferential grooves prevent the special belt 15 from sliding off the rollers 14 and 26. In the exemplary embodiment shown, the profiling 28 and 29 run over the entire width of the special belt 15 or the rollers 14 and 26. They interlock with one another. Furthermore, the bandage 3 is provided with circumferential grooves 27 which are semicircular in cross section. The blasting material 7 is located in these circumferential grooves 27 of the bandage 3 and the special belt 15. The resulting beam 21 strikes the object 20 to be blasted. The handle 22 is fastened to the housing 5.

Dreht sich die Scheibe 2 mit der Bandage 3 in der in Figur 1 angegebenen Pfeilrichtung, so wird das zwischen der Bandage 3 und dem Spezialriemen 15 über das Strahlgutzuführungsrohr 11 eingeführte Strahlgut 7 erfaßt und auf die erforderliche Geschwindigkeit gebracht, so daß es als Strahl 21 auf das zu bearbeitende Objekt 20 trifft. Mit dem Schwenkhebel 18 kann durch Verstellen der Ringscheibe 12 eine Änderung der austretenden Strahlrichtung bewirkt werden. Durch Drehen des Gewindespannbolzens 16 wird über die Rollen 14 und 26 eine Veränderung der Spannung des Spezialriemens 15 ermöglicht.If the disk 2 with the bandage 3 rotates in the direction of the arrow shown in FIG. 1, the blasting material 7 introduced between the bandage 3 and the special belt 15 via the blasting material feed pipe 11 is grasped and brought to the required speed so that it hits the object 20 to be processed as a beam 21. With the swivel lever 18, a change in the emerging beam direction can be effected by adjusting the annular disc 12. By turning the threaded clamping bolt 16, a change in the tension of the special belt 15 is made possible via the rollers 14 and 26.

Anstelle dieses Schwenkhebels 18 wird in der gemäß Figur 3 dargestellten Ausführungsform die Ringscheibe 12 über eine Exzenterscheibe 24 mit Motor in Schwenkbewegungen gebracht. Die Schubstange 25 stellt die Verbindung zwischen der Exzenterscheibe 24 und der Ringscheibe 12 her. In dieser Ausführungsform weist die Strahlgutschleuder eine kontinuierlich arbeitende und schwenkende Ringscheibe 12 auf. Wird diese Vorrichtung mit der Exzenterscheibe 24 betrieben, so erhält man im Gegensatz zu dem Strahl 21 die größere und langgezogene Strahlfläche 23. Diese Zusatzeinrichtung hat sehr große Vorteile, weil man die Strahlflächenlänge der Werkstückfläche anpassen kann. Es geht kein Strahlgut ins Leere, die Flächen werden intensiver getroffen und sie werden in einer kürzeren Zeit bestrahlt. Eine manuelle Bedienung des Schwenkhebels 18 gemäß Figur 1 ist durch die Bedienungsperson nicht auf derartig gleichmäßige Weise möglich, so daß ein unsauberes Strahlbild entsteht.Instead of this pivoting lever 18, in the embodiment shown in FIG. 3, the annular disc 12 is brought into pivoting movements by means of an eccentric disc 24 with a motor. The push rod 25 establishes the connection between the eccentric disc 24 and the annular disc 12. In this embodiment, the blasting material centrifuge has a continuously operating and pivoting annular disc 12. If this device is operated with the eccentric disc 24, the larger and elongated beam surface 23 is obtained in contrast to the beam 21. This additional device has very great advantages because the beam surface length can be adapted to the workpiece surface. No blasting material is lost, the areas are hit more intensively and they are irradiated in a shorter time. Manual operation of the swivel lever 18 according to FIG. 1 is not possible by the operator in such a uniform manner, so that an unclean spray pattern is produced.

Bei jeder der dargestellten Ausführungsformen läuft der Spezialriemen 15 mit Umfangsrillen in den beiden gerillten Spannrollen 14 und 26 und verhindert somit ein Ablaufen von der Bandage 3 bei ungleichmäßiger Zuführung von Strahlgut. Gemäß Figur 2 führt die Bandage 3 den Spezialriemen 15 seitlich durch Bordränder, so daß auch hierdurch ein Ablaufen von der Bandage 3 verhindert wird. Durch die Vorspannung des Spezialriemens 15 wird dieser gegen die Bandage 3 gepreßt, wirkt kraftschlüssig und schließt dadurch das Strahlgut 7 in den tiefen Rillen 27 der Bandage 3 ein und bewirkt somit eine Beschleunigung durch die Bandage 3 und den Spezialriemen 15, was einem Riementrieb ähnelt. Das Spannen des Spezialriemens 15 und das Verstellen der geteilten Ringscheibe 12 wird durch den Gewindespannbolzen 16 mit Rechts- und Linksgewinde bewirkt.In each of the illustrated embodiments, the special belt 15 runs with circumferential grooves in the two grooved tensioning rollers 14 and 26 and thus prevents the bandage 3 from running off when the blasting material is supplied unevenly. According to FIG. 2, the bandage 3 guides the special belt 15 laterally through the edges of the rim, so that this also prevents the bandage 3 from running off. The pretensioning of the special belt 15 presses it against the bandage 3, acts in a force-locking manner and thereby encloses the blasting material 7 in the deep grooves 27 of the bandage 3 and thus causes acceleration by the bandage 3 and the special belt 15, which is similar to a belt drive. The tensioning of the special belt 15 and the adjustment of the split washer 12 is effected by the threaded clamping bolt 16 with right and left hand threads.
