Description

Die Erfindung bezieht sich auf einen Schraubkopf der im Oberbegriff des Patentanspruchs genannten Gattung.The invention relates to a screw head of the type mentioned in the preamble of the claim.

Bei einem aus der DE-A-34 16 551 bekannten Schraubkopf dieser Art sind die gegeneinander bewegbaren Backen in Linearführungen einer Führungsplatte des Trägers verschiebbar gelagert und werden über im Träger schwenkbar gelagerte Hebel bewegt. Als Antrieb dient eine Zylinderkolbeneinheit, die im Träger gleichachsig zur Drehachse angeordnet ist, und eine aus Kolben, Kolbenstange und Betätigungskopf bestehende Antriebseinheit aufweist. Der Betätigungskopf ist vorzugsweise als Gelenkmuffe ausgebildet, mit der die Hebel über Zwischenlenker verbunden sind. Er kann auch als Außenkonus ausgebildet sein, mit dem die Hebel zur Betätigung der Backen zusammenwirken. Da der bekannte Schraubkopf aus vielen Einzelteilen zusammengesetzt ist, ist der Aufwand zu dessen Herstellung und Montage hoch. Außerdem beeinträchtigt das Spiel in den Gelenken und Lagern der Teile die Greifgenauigkeit der Backen. Ferner ist der Außendurchmesser des Schließkopfs relativ groß, so daß wegen der damit verbundenen hohen Massenträgheit ein in engen Toleranzgrenzen liegendes Anzugsmoment für Schraubkappen nicht erzielbar ist.In a screw head of this type known from DE-A-34 16 551, the mutually movable jaws are displaceably mounted in linear guides of a guide plate of the carrier and are moved by levers pivotably mounted in the carrier. A cylinder-piston unit serves as the drive, which is arranged in the carrier coaxially with the axis of rotation and has a drive unit consisting of piston, piston rod and actuating head. The actuating head is preferably designed as a joint sleeve with which the levers are connected via intermediate links. It can also be designed as an outer cone with which the levers for actuating the jaws interact. Since the known screw head is composed of many individual parts, the effort for its manufacture and assembly is high. In addition, the play in the joints and bearings of the parts affects the gripping accuracy of the jaws. Furthermore, the outer diameter of the closing head is relatively large, so that a tightening torque for screw caps which is within narrow tolerance limits cannot be achieved because of the high inertia associated therewith.

Ferner ist aus der US-A-1 797 679 ein Schraubkopf bekannt, bei dem ein Betätigungskonus an einer Stange befestigt ist, die eine rohrförmige Antriebsspindel durchsetzt. Zum Greifen und Festhalten einer Verschlußkappe wird die Stange mit dem Betätigungskonus von einer Rolle und einer Kurve axial verschoben, wobei die mit den Backen verbundenen Hebel im Sinne eines Schließens verschwenkt werden. Der bekannte Schraubkopf hat in Verbindung mit der Spindel und der Betätigungsstange eine verhältnismäßig große Masse, so daß infolge deren Trägheit ein feinfühliges Aufschrauben mit gleichförmigem Anzugsmoment nicht möglich ist.Furthermore, a screw head is known from US-A-1 797 679, in which an actuating cone is attached to a rod which passes through a tubular drive spindle. To grip and hold a closure cap, the rod with the actuating cone is axially displaced by a roller and a curve, the levers connected to the jaws being pivoted in the sense of a closure. The known screw head has a relatively large mass in connection with the spindle and the actuating rod, so that due to their inertia a sensitive screwing with a uniform tightening torque is not possible.

Der Erfindung liegt die Aufgabe zugrunde, einen Schraubkopf zu schaffen, mit dem Schraubkappen mit einem in einem engen Toleranzbereich liegenden Anzugsmoment auf Behälter aufgeschraubt werden können. Die Lösung dieser Aufgabe ist im Kennzeichen des Anspruchs angegeben.The invention has for its object to provide a screw head with which screw caps with a tightening torque lying in a narrow tolerance range can be screwed onto containers. The solution to this problem is specified in the characterizing part of the claim.

Der erfindungsgemäße Schraubkopf mit den kennzeichnenden Merkmalen des Anspruchs 1 hat den Vorteil, daß seine Masse auf kleinem Durchmesser angeordnet ist und dadurch ein sehr kleines Trägheitsmoment aufweist, so daß Drehverschlüsse mit einem vorbestimmten Anzugsmoment in engen Grenzen festgezogen werden können. Ferner ist mit ihm ein kräftiges Greifen der Verschlüsse möglich, so daß er universell einsetzbar ist. Die Haltekraft der Backen ist einfach durch Veränderung des Druckes für die Zylinderkolbeneinheit einstellbar, die ebenfalls kurze Betätigungszeiten gewährleistet. Schließlich hat er einen einfachen und übersichtlichen Aufbau.The screw head according to the invention with the characterizing features of claim 1 has the advantage that its mass is arranged on a small diameter and thus has a very small moment of inertia, so that rotary locks can be tightened with a predetermined tightening torque within narrow limits. Furthermore, a strong gripping of the closures is possible with it, so that it can be used universally. The holding force of the jaws can be easily adjusted by changing the pressure for the cylinder-piston unit, which also ensures short actuation times. After all, it has a simple and clear structure.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen Figur 1 einen Schraubkopf in Seitenansicht teilweise im Schnitt in geschlossener Stellung und Figur 2 den Schraubkopf nach Figur 1 im Schnitt in geöffneter Stellung.An embodiment of the invention is shown in the drawing and explained in more detail in the following description. FIG. 1 shows a screw head in a side view, partly in section in the closed position, and FIG. 2 shows the screw head according to FIG. 1 in section in the open position.

Ein Schraubkopf 10 ist am unteren Ende einer taktweise drehbaren sowie auf- und abbewegbaren Spindel 11 auswechselbar befestigt. Er hat einen zweiteiligen Träger 12, der aus einem auf die Spindel 11 aufgeschraubten Kopfteil 13 und aus einer auf diesen aufgeschraubten Hülse 14 besteht. Am unteren Ende der Hülse 14 ist ein radial nach innen gerichteter Bund angeordnet in den eine Hülse 16 eingeschraubt ist. Ferner sind am unteren Ende der Hülse 14 und in derem Bund 15 vier radiale Schlitze 17 kreuzweise angeordnet. In jedem der Schlitze 17 ist ein Hebel 18 auf einem Stift 19 schwenkbar gelagert. Am unteren aus der Hülse 14 nach unten vorragenden Arm 21 jedes Hebels 18 schließt sich ein Haltebacken 20 an. Die vier Haltebacken 20 bilden eine Zange zum Greifen und Festhalten einer Verschlußkappe 1. Der nach oben sich erstreckende Arm 22 greift in das Innere der Hülse 14 und liegt mit seiner radial nach innen gerichteten, ballig ausgebildeten Fläche an einem Betätigungskonus 24 an. Eine auf ihrer Außenseite anliegende Ringfeder 25 drückt die oberen Arme 22 gegen den Betätigungskonus 24.A screw head 10 is fastened at the lower end of a spindle 11 which can be rotated in cycles and moved up and down. It has a two-part carrier 12, which consists of a head part 13 screwed onto the spindle 11 and a sleeve 14 screwed onto it. At the lower end of the sleeve 14, a radially inward collar is arranged into which a sleeve 16 is screwed is. Furthermore, four radial slots 17 are arranged crosswise at the lower end of the sleeve 14 and in the collar 15 thereof. In each of the slots 17, a lever 18 is pivotally mounted on a pin 19. A holding jaw 20 connects to the lower arm 21 of each lever 18, which projects downward from the sleeve 14. The four holding jaws 20 form pliers for gripping and holding a closure cap 1. The arm 22, which extends upwards, engages in the interior of the sleeve 14 and, with its radially inwardly directed, spherically shaped surface, bears against an actuating cone 24. An annular spring 25 resting on its outside presses the upper arms 22 against the actuating cone 24.

Der Betätigungskonus 24 ist mit einer druckmittelbetätigen Zylinderkolbeneinheit 26 verbunden. Er ist integraler Teil des Kolbens 27 der Zylinderkolbeneinheit 26 und schließt sich als Übergang vom Kolben 27 zu dessen nach unten vorstehenden Kolbenstange 28 an. Die Kolbenstange 28 hat eine Sackbohrung 29, in der eine sich am Boden der Büchse 16 abstützende Schraubenfeder 30 angeordnet ist, die den Kolben 27 nach oben drückt. Der Kolben 27 ist in einem vom Kopfteil 13 nach unten vorstehendem Ansatz verschiebbar geführt, der als Zylinderbüchse 31 ausgebildet ist. Der von der Zylinderbüchse 31 umgebene Arbeitsraum 32 der Zylinderkolbeneinheit 26 ist über eine Bohrung 33 im Kopfteil 13, eine Längsbohrung 34 in der Spindel 11, eine Leitung 35 und über ein elektromagnetisch betätiges Schaltventil 36 sowie ein einstellbares Druckminderventil 37 mit einer Druckmittel-, vorzugsweise einer Druckluftquelle 38 verbunden. Die Haltekraft der Haltebacken 20 läßt sich in einfacher Weise durch Einstellen des Druckes an dem Druckminderventil 37 verändern.The actuating cone 24 is connected to a pressure-actuated cylinder piston unit 26. It is an integral part of the piston 27 of the cylinder-piston unit 26 and connects as a transition from the piston 27 to the piston rod 28 which projects downwards. The piston rod 28 has a blind bore 29 in which a helical spring 30, which is supported on the bottom of the bush 16 and which pushes the piston 27 upward, is arranged. The piston 27 is displaceably guided in a projection projecting downward from the head part 13, which is designed as a cylinder liner 31. The working space 32 of the cylinder-piston unit 26 surrounded by the cylinder liner 31 is via a bore 33 in the head part 13, a longitudinal bore 34 in the spindle 11, a line 35 and an electromagnetically operated switching valve 36 and an adjustable pressure reducing valve 37 with a pressure medium, preferably one Compressed air source 38 connected. The holding force of the holding jaws 20 can be changed in a simple manner by adjusting the pressure on the pressure reducing valve 37.

Der oben beschriebene Schraubkopf arbeitet wie folgt:
Bei drucklosem Arbeitsraum 32 der Zylinderkolbeneinheit 26 schiebt die Schraubenfeder 30 den Kolben 27 nach oben, so daß die oberen Arme 22 der Hebel 18 unter der Wirkung der Ringfeder 25 an der Kolbenstange 28 anliegen (Figur 2). Dabei sind die Haltebacken 20 von den Hebeln 18 nach außen in eine geöffnete Stellung verschwenkt. In dieser Stellung wird von unten her eine Schraubkappe 1 zwischen die Haltebacken 20 bis zur Analge an der Büchse 16 geschoben. Darauf wird durch Umschalten des Schaltventils 36 Druckluft aus der Druckluftquelle 38 in den Arbeitsraum 32 eingelassen, so daß durch den Druckaufbau im Arbeitsraum 32 der Kolben 27 nach unten verschoben wird. Dabei schiebt sich der Betätigungskonus 24 mehr und mehr zwischen die oberen Arme 22 der Hebel 18, so daß diese verschwenkt werden und dabei die Haltebacken 20 am Umfang der Kappe 1 zur Anlage kommen. Je nach dem durch das Druckminderventil 37 eingestellten Druck im Arbeitsraum 32 ist der von den Haltebacken 20 auf die Schraubkappe 1 ausgeübte Druck einstellbar von leicht bis fest. Nach Verbringen eines zu verschließenden Behälters 2 in Ausrichtung mit dem Schraubkopf 10 und absenken der Spindel 11 wird durch Drehen der Spindel und damit des Schraubkopfs 10 die erfaßte Verschlußkappe 1 auf den Behälter 2 aufgeschraubt. Das Festziehmoment der Verschlußkappe 1 wird am Antrieb der Spindel 11 eingestellt. Da die Spindel 11 und der Schraubkopf 10 eine geringe Trägheit haben, ist ein gleichförmiges Festschrauben von Verschlußkappen 1 auf Behältern möglich. Ferner sind durch die geringen Massen der Zylinderkolbeneinheit und des Betätigungskonus kurze Öffnungs- und Schließzeiten der Haltebacken möglich.The screw head described above works as follows:
When the working space 32 of the cylinder-piston unit 26 is depressurized, the coil spring 30 pushes the piston 27 upward, so that the upper arms 22 of the lever 18 bear against the piston rod 28 under the action of the annular spring 25 (FIG. 2). The holding jaws 20 are pivoted outward from the levers 18 into an open position. In this position, a screw cap 1 is pushed from below between the holding jaws 20 to the bush 16. Then, by switching the switching valve 36, compressed air from the compressed air source 38 is admitted into the working space 32, so that the piston 27 is displaced downward by the pressure build-up in the working space 32. The actuating cone 24 moves more and more between the upper arms 22 of the levers 18 so that they are pivoted and the holding jaws 20 come to rest on the circumference of the cap 1. Depending on the pressure set by the pressure reducing valve 37 in the working space 32, the pressure exerted by the holding jaws 20 on the screw cap 1 can be adjusted from light to firm. After moving a container 2 to be closed in alignment with the screw head 10 and lowering the spindle 11, the detected cap 1 is screwed onto the container 2 by turning the spindle and thus the screw head 10. The tightening torque of the cap 1 is set on the drive of the spindle 11. Since the spindle 11 and the screw head 10 have a low inertia, a uniform screwing of the closure caps 1 onto containers is possible. Furthermore, the small masses of the cylinder-piston unit and the actuating cone mean that the holding jaws can be opened and closed quickly.
