Abstract

Cylindrical workpieces with a diameter to length ratio of 1:1 are fed to high capacity machines, such as centre less grinders. The drum rotates about an axis inclined to its cone centre line and a chute brings the workpieces through an opening in the larger diameter end. A number of channel sections are contained by the inside conical surface and in these, workpieces lodge and are lifted into an inclined slide which protrudes into the drum from the small diameter end. This slide leads the workpieces into the machines.

Description

Vorrichtung zum geordneten Zuführen zylindrischer Werkstücke Die Erfindung betrifft eine Vorrichtung zum Ordnen und Zuführen zylindrischer Werkstücke zu Werkzeugmaschinen, insbesondere solcher zylindrischer Teile, deren Verhältnis länge : Durchmesser = 1 : 1 betrugt.Device for the orderly feeding of cylindrical workpieces The invention relates to a device for arranging and feeding cylindrical workpieces to machine tools, especially those cylindrical parts whose ratio length: diameter = Was 1: 1.

Zum Zuführen zylindrischer Werkstücke zu Rochleistungswerkzeugmaschinen, beispielsweise spitzenlosen Außenrundschleifmaschinen, bei denen die Werkstücke mit einer erhöhten Durchlaufgeschwindigkeit den Schleifspal passieren, kommen vorwiegend Vibrationsförderer oder Vorrichtungen nach dem Prinzip des Trichterbunkers mit Hub- und Drehbewegung und zentraler Ableitung zum .Sinsatz. Nähern sich die Werkstücke dem Verhältnis Länge Durchmesser = 1 : 1 so sind die genannten Vorrichtungen nicht mehr einsetzbar. Das Ausrichten aller zylindrischen werkstücke in Achsrichtung im Werkstückstrang ist nicht mehr gewährleistet. Gelangen ungeordnete Werkstücke in den Schleifspalt, so ist eine Beschädigung der Schleifwerkzeuge unvermeidbar. For feeding cylindrical workpieces to high-performance machine tools, For example, centerless external cylindrical grinding machines where the workpieces Pass the grinding gap at an increased throughput speed, come predominantly Vibratory conveyors or devices based on the principle of the hopper with lifting and rotary movement and central derivation for use. The workpieces approach the ratio length diameter = 1: 1 so the devices mentioned are not more applicable. The alignment of all cylindrical workpieces in the axial direction in Workpiece string is no longer guaranteed. If disordered workpieces get into the grinding gap, damage to the grinding tools is unavoidable.

Der Zweck der Erfindung besteht darin, mittels einer geeigneten Vorrichtung auch für erhöhte Werkstückdurchlaufgeschwindigkeiten einen geordneten Werkstückstrang zu erhalten, um die aufgezeigten Nachteile, Beschädigung von Schleifwerkzeugen durch ungeordnet in den Schleifspalt einlaufende Werkstücke, auszuschließen. Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen zum in Achsrichtung geordneten Zufürhren zylindrischer Werkstücke in höheren Stückzahlen zu Werkzeugmaschinen, insbesondere zylindrische Werkstücke mit einem Verhältnis Länge : Durchmesser = 1 : 1 zu Hochleistungswerkzeugmaschinen, beispielsweise spitzenlosen Außenrundschleifmaschinen.The purpose of the invention is by means of a suitable device an orderly work piece strand even for increased workpiece throughput speeds to get the disadvantages outlined, damage to grinding tools by Workpieces entering the grinding gap in a disorderly manner are to be excluded. The invention is based on the task of a device to create in Axially ordered feeding of cylindrical workpieces in higher quantities to machine tools, especially cylindrical workpieces with a ratio Length: Diameter = 1: 1 for high-performance machine tools, for example centerless External cylindrical grinding machines.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß in Längsrichtung am Innenmantel eines um seine geneigte Längsachse rotierenden, beidseitig abgedeckten Hohlkegelstumpf werlstückaufnehmende profilleisten angeordnet sind, die teilweise durch eine foststehende, segmentförmige, in eine werkstückabf-iüir inne auslaufende Leiteinrichtung abgedeckt sind.According to the invention the object is achieved in that in the longitudinal direction on the inner jacket of a rotating, covered on both sides around its inclined longitudinal axis Hollow truncated cone werlstückaufnahmende profile strips are arranged, the partially through a post-standing, segment-shaped, inwardly terminating workpiece dispenser Guiding device are covered.

Die irofilleisten sind vorzugsweise federnd am Innenmantel des Hohlkegelstumpfes gehaltert. Die Form der die Werkstücke aufnehmenden Profilleis-te ist der Zylinderform der .Jerkstücke angepaßt, wobei die eine in der Drehrichtung des rotierenden Hohlkegelstumpfes liegende kante abgeschrägt und die dieser gegenüberliegenden Kante angefast ist.The irofil strips are preferably resilient on the inner surface of the hollow truncated cone held. The shape of the profile strip that holds the workpieces is cylindrical the .Jerkteile adapted, one in the direction of rotation of the rotating hollow truncated cone the lying edge is beveled and the edge opposite this is chamfered.

Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden. In der zugehörigen Zeichnung zeigen: Sig. 1: die Vorderansicht der Vorrichtung im Schnitt, Fig. 2: den Schnitt A-A nach Fig. 1.The invention is to be described in more detail below using an exemplary embodiment explained. In the accompanying drawing show: Sig. 1: the front view of the device in section, FIG. 2: the section A-A according to FIG. 1.

Die zylindrischen werkstücke 8 werden wahllos in den Innenraum eines Rohlkegelstumpfes 2 eingelegt oder über eine Werkstückzuführrinne 1 ungeordnet zugeführt, Der Innenraum des Hohlkegelstumpfes 2 ist durch eine hintere Abdeclclng 3 und eine vordere Abdeckung 4 begrenzt. Mm Innenmantel des Hohlkegelstumpfes 2 2 sind Profilleisten 5 angeordnet, die vorzugsweise federnd gehaltert sind. Die Profilleisten 5 sind der Zylinderform der Werkstücke @ angepaßt. Die in der Drehrichtung des rotierende Rohlkegelstumpfes 2 fließende kante der Profilleisten 5 ist abgeschrägt, während die andere, der Abschra@ung gegenüberliegende Kante angefast ist. Im oberen Bereich des Hohlkegelstumpfes 2 ist eine feststehende, segnertförmige Leitein.riclltuny 7 vor.esehen, die eine Anzahl Profilleisten 5 abdeckt. Die Leiteinrichtung 7 lut in eine Werkstückabführrinne 6 aus.The cylindrical workpieces 8 are randomly in the interior of a Raw truncated cone 2 inserted or fed randomly via a workpiece feed channel 1, The interior of the hollow truncated cone 2 is through a rear Abdeclclng 3 and a front cover 4 limited. Mm inner surface of the hollow truncated cone 2 2 are profile strips 5 arranged, which are preferably supported resiliently. the Profile strips 5 are adapted to the cylindrical shape of the workpieces @. The one in the direction of rotation of the rotating Rohlkegelstumpfes 2 flowing edge of the profile strips 5 is beveled while the other edge opposite the bevel is chamfered. In the upper area of the hollow truncated cone 2 is a fixed, Segnert-shaped Leitein.riclltuny 7 vor.esehen, which covers a number of profile strips 5. The guide device 7 lut into a workpiece discharge channel 6.

Infolge der Rotation des Hohlkegelstumpfes 2 um seine nach vorn geneigte Längsachse in der in Fig. 2 angegebenen Drehrichtung werden die Werkstücke 8 von den Profilleisten 5 ungeordnet aufgenommen. Auf Grund des besonderen Profiles der Profilleisten 5 kippen "falsch" liegende Werkstücke 8 durch ihre labile Lage in den Profilleisten 5 in einer bestimmten Förderhöhe über die anefaste Kante ab und fallen zurück. Die geordneten und als axial gerichteter Strang Werkstücke 0 werden von der Leiteinrichtung 7 am Herausfallen aus den Profilleisten 5 gehindert. In der vorzugsweise obersten Stellung des Hohlkegelstumpfes 2 gleiten die Werkstücke 8 durch ihr Eigengewicht in die Werkstückabführrinne 6 und zum Verbraucher.As a result of the rotation of the hollow truncated cone 2 about its inclined forward Longitudinal axis in the direction of rotation indicated in Fig. 2, the workpieces 8 of the profile strips 5 added randomly. Due to the special profile of the Profile strips 5 tilt "incorrectly" positioned workpieces 8 due to their unstable position the profile strips 5 in a certain delivery height over the beveled edge and fall behind. The ordered and axially oriented strand workpieces become 0 prevented by the guide device 7 from falling out of the profile strips 5. In the preferably uppermost position of the hollow truncated cone 2 slide the workpieces 8 by their own weight in the workpiece discharge channel 6 and to the consumer.
