Description

VORRICHTUNG ZUM EINPRÄGEN VON KENNZEICHEN IN SICH BEWEGENDE TEILE DEVICE FOR IMPRESSING LABELS IN MOVING PARTS
Die Erfindung bezieht sich auf eine Vorrichtung zum Kennzeichnen von sich in Laufrichtung eines Rollganges bewegenden Teilen mit zumindest einem Zeichenträger, welcher ein Zeichen trägt, wobei dieser zumindest eine Zeichenträger am Umfang eines Prägerades eingesetzt ist.The invention relates to a device for marking parts moving in the direction of travel of a roller table with at least one character carrier which bears a character, said at least one character carrier being inserted on the circumference of an embossing wheel.
Eine Aufgabe der Erfindung ist die Schaffung einer Vorrichtung, die auch bei hohen Laufgeschwindigkeiten der sich auf dem Rollgang bewegenden, zu kennzeichnenden Teile ein mit beliebigen Abständen aufeinanderfolgendes Kennzeichnen dieser Teile mit einem oder mehreren Zeichen ermöglicht, wobei es sich hier um verschiedene, aber auch ganz oder teilweise gleiche Zeichen handeln kann.It is an object of the invention to provide a device which, even at high running speeds of the parts to be marked which are moving on the roller table, makes it possible to mark these parts successively with any spacing using one or more characters, these being different but also entirely or partially act the same characters.
Diese Aufgabe wird ausgehend von einer Vorrichtung der eingangs genannten Art durch ein synchron zur Geschwindigkeit der zu kennzeichnenden Teile mit einem Antrieb hochbeschleunigbares, in einer Prägeeinheit drehbar gelagertes exzentrisches Prägerad, dessen auf die zu kennzeichnenden Teile ausgeübte Kraft stufenlos und konstant einstellbar ist, wobei die horizontale, vertikale und gegebenenfalls geneigte Ausrichtung der Prägeposition des Prägerades einstellbar ist, und durch ein Entfemungsmeßgerät für die sich bewegenden Teile zum Steuern eines Horizontalantriebes für die Nachführung der das Prägerad tragenden Prägeeinheit gelöst.This task is based on a device of the type mentioned by an eccentric embossing wheel which can be accelerated and synchronized with the speed of the parts to be marked with a drive and which is rotatably mounted in an embossing unit, the force exerted on the parts to be marked is continuously and constantly adjustable, the horizontal , vertical and optionally inclined alignment of the embossing position of the embossing wheel is adjustable, and solved by a distance measuring device for the moving parts for controlling a horizontal drive for tracking the embossing unit carrying the embossing wheel.
Die Erfindung geht somit davon aus, daß durch diese Vorrichtung ein schnelles und präzises, in kurzen Abständen hintereinanderfolgendes Kennzeichnen von sich in Laufrichtung eines Rollganges bewegenden Teilen mit Zeichen möglich ist, wobei es sich sowohl um einzelne, aber auch mehrere verschiedene oder ganz oder teilweise gleiche Zeichen handeln kann. Durch die Exzentrizität des Prägerades wird die Prägeeinheit bei der Berührung des Rades mit den zu kennzeichnenden Teilen in ihrem Führungssystem hochgehoben, und die Kennzeichnung der Teile erfolgt mit einer konstanten, von der Prägeeinheit ausgeübten Kraft. Dabei ist eine ständige horizontale Nachfuhrung des Prägerades in einer Position oberhalb der zu kennzeichnenden Teile mit Hilfe eines Entfernungsmeßgerätes möglich.The invention is therefore based on the fact that this device enables a fast and precise marking of parts moving in the running direction of a roller table with characters in quick succession, characters which are individual, but also several different or completely or partially the same Characters can act. Due to the eccentricity of the stamping wheel, the stamping unit is lifted up in its guide system when the wheel touches the parts to be marked, and the parts are marked with a constant force exerted by the stamping unit. A constant horizontal tracking of the embossing wheel in a position above the parts to be marked is possible with the aid of a distance measuring device.
Weiters ist es auch vorteilhaft, wenn die Prägeeinheit über den Horizontalantrieb in Führungen horizontal, quer zur Laufrichtung der zu kennzeichnenden Teile verschiebbar ist, und einen Schwenkantrieb zum Verschwenken der Prägeeinheit in eine Prägeposition des Prägerades senkrecht oder schräg oberhalb der zu kennzeichnenden Teile aufweist. Mit Hilfe dieser An- triebe kann das in der Prägeeinheit gelagerte Prägerad hinsichtlich seiner horizontalen Prägeposition sowie senkrecht oder schräg oberhalb der zu kennzeichnenden Teile positioniert werden.Furthermore, it is also advantageous if the embossing unit can be displaced horizontally in guides via the horizontal drive, transversely to the running direction of the parts to be marked, and has a swivel drive for pivoting the embossing unit into an embossing position of the embossing wheel vertically or obliquely above the parts to be marked. With the help of this drives, the embossing wheel mounted in the embossing unit can be positioned with respect to its horizontal embossing position and vertically or obliquely above the parts to be marked.
Weiters kann es auch zweckmäßig sein, wenn die Vorrichtung zumindest einen Antrieb zur Anstellung des Prägerades gegen die sich bewegenden Teile besitzt, wobei ein Antrieb zum Grobeinstellen, und ein Antrieb zum Feineinstellen des Prägerades gegen die zu kennzeichnenden Teile verwendet ist. Mit dem Antrieb zum Grobeinstellen wird das Prägerad in eine Vorposition oberhalb der zu kennzeichnenden Teile gebracht, der Antrieb zum Feineinstellen bringt das Prägerad in seine Endstellung oberhalb der zu kennzeichnenden Teile unmittelbar vor dem Prägevorgang.Furthermore, it can also be expedient if the device has at least one drive for positioning the stamping wheel against the moving parts, a drive for rough adjustment and a drive for fine adjustment of the stamping wheel against the parts to be identified. With the drive for rough adjustment, the embossing wheel is brought into a preposition above the parts to be marked, the drive for fine adjustment brings the embossing wheel into its end position above the parts to be marked immediately before the embossing process.
Empfehlenswert ist es auch, wenn die Exzentrizität des Prägerades so gewählt ist, daß unmittelbar vor dem am Umfang des Prägerades eingesetzten zumindest einen Zeichenträger das Prägerad die zu kennzeichnenden Teile berührt und von diesen nach oben gegen eine konstante Kraft gedrückt wird. Durch dieses Gegenregeln mit einer konstanten, einstellbaren Kraft findet nun während der Weiterdrehung des Prägerades der eigentliche Kennzeichnungsvorgang der Teile mit dem zumindest einen am Umfang des Prägerades eingesetzten Zeichenträger statt.It is also advisable if the eccentricity of the embossing wheel is selected such that the embossing wheel touches the parts to be marked immediately in front of the at least one drawing carrier used on the circumference of the embossing wheel and is pressed upwards by them against a constant force. Through this counter-regulation with a constant, adjustable force, the actual marking process of the parts with the at least one character carrier inserted on the circumference of the embossing wheel now takes place while the embossing wheel continues to rotate.
Auch ist es von Vorteil, wenn die von dem Prägerad auf die zu kennzeichnenden Teile ausgeübte, konstante Kraft über einen hydraulischen Antrieb einstellbar ist. Mit diesem Antrieb kann die Kraft in Abhängigkeit von dem jeweils zu kennzeichnenden Teil eingestellt und während des Prägevorganges konstant gehalten werden.It is also advantageous if the constant force exerted by the embossing wheel on the parts to be marked can be adjusted via a hydraulic drive. With this drive, the force can be set depending on the part to be labeled and kept constant during the stamping process.
Schließlich ist auch eine Vorrichtung vorgesehen, bei welcher die sich in Laufrichtung des Rollganges bewegenden Teile Profile sind, wobei sich hier die Erfindung besonders bewährt, beispielsweise falls mehrere Zeichen in Abständen in Eisenbahnschienen geprägt werden sollen.Finally, a device is also provided in which the parts moving in the running direction of the roller table are profiles, the invention being particularly useful here, for example if several characters are to be embossed at intervals in railroad tracks.
Im folgenden ist die Erfindung an Hand einer beispielhaften Ausfuhrungsform erläutert, die in der Zeichnung dargestellt ist. In dieser zeigtThe invention is explained below using an exemplary embodiment which is shown in the drawing. In this shows
die einzige Figur eine schematische Seitenansicht der erfindungsgemäßen Vorrichtung zum Kennzeichnen von sich in Laufrichtung eines Rollganges bewegenden Teilen.the single figure is a schematic side view of the device according to the invention for marking parts moving in the direction of travel of a roller table.
Mit einem Horizontalantrieb 4 wird über horizontal angeordnete Führungen 5 ein Horizontalschlitten 6, in Abhängigkeit von einer theoretischen horizontalen Lage der zu kennzeichnenden Teile auf einem Rollgang 1, aus seiner hinteren Endlage auf einem Grundrahmen 7 in die für die jeweils zu kennzeichnenden Teile erforderliche Vorposition gefahren. Bei diesen zu kennzeichnenden Teilen handelt es sich in der Regel um Profile, Schienen, Rohre, etc. („Langgut"), welche im allgemeinen im noch warmen Zustand gekennzeichnet werden, doch kann es sich auch um nicht langgestreckte Einzelteile handeln.With a horizontal drive 4, a horizontal slide 6, depending on a theoretical horizontal position of the parts to be marked on a roller table 1, is moved from its rear end position on a base frame 7 into the pre-position required for the parts to be marked. These parts to be labeled are usually profiles, rails, pipes, etc. ("long goods"), which are generally marked while still warm, but they can also be non-elongated individual parts.
Je nach Art der zu kennzeichnenden Teile wird gleichzeitig oder unmittelbar nach diesem Vorgang eine Prägeeinheit 8 um einen Drehpunkt 9 mit einem zentrisch zur Drehachse angeordneten Schwenkantrieb 10 in eine Position senkrecht oder schräg zur Kennzeichnungsfläche gedreht und in dieser Position verdrehgesichert.Depending on the type of parts to be marked, an embossing unit 8 is rotated simultaneously or immediately after this process about a pivot point 9 with a swivel drive 10 arranged centrally to the axis of rotation into a position perpendicular or obliquely to the marking surface and secured against rotation in this position.
Je nach Art der sich am Rollgang 1 bewegenden Teile wird ebenfalls gleichzeitig oder unmittelbar nach dem Verschwenken die Prägeeinheit 8 mit einem zur Grobeinstellung dienenden hydraulischen Antrieb 11 in eine vertikal zur Kennzeichnungsfläche erforderliche Vorposition gefahren und oberhalb der theoretischen Kennzeichnungsfläche mit einer Klemmvorrichtung 12 geklemmt.Depending on the type of parts moving on the roller table 1, the embossing unit 8 is also moved simultaneously or immediately after the pivoting with a hydraulic drive 11 serving for rough adjustment into a pre-position required vertically to the marking surface and clamped above the theoretical marking surface with a clamping device 12.
Nach Aktivierung eines Entfemungsmeßgerätes 3 wird der Horizontalabstand der Prägeeinheit zu dem jeweils zu kennzeichnenden Teil ständig aktiv gemessen. Anhand dieser mit Hilfe des Entfemungsmeßgerätes 3 ermittelten Meßdaten wird der Horizontalschlitten 6 über dessen Horizontalantrieb 4 ständig den zu kennzeichnenden Teilen nachgefühlt, sodaß den horizontalen Abweichungen der Teile von einer Referenzposition auf dem Rollgang 1 folgend, ein drehbar in der Prägeeinheit 8 gelagertes und von einem Antrieb 15 antreibbares, exzentrisches Prägerad 2 ständig und präzise über der erforderlichen Kennzeichnungsfläche der Teile oder Profile gehalten wird.After activation of a distance measuring device 3, the horizontal distance of the embossing unit from the part to be identified is actively measured. On the basis of this measurement data determined with the aid of the distance measuring device 3, the horizontal slide 6 is constantly replenished with the parts to be labeled via its horizontal drive 4, so that the horizontal deviations of the parts from a reference position on the roller table 1 are followed by a drive which is rotatably mounted in the embossing unit 8 15 drivable, eccentric embossing wheel 2 is constantly and precisely held over the required marking area of the parts or profiles.
Unmittelbar vor dem zu erfolgenden Kennzeichnungsvorgang wird die Prägeeinheit 8 über einen weiteren hydraulischen Antrieb 13, der zur Feineinstellung der Prägeeinheit dient, in dessen untere Endlage vertikal oberhalb der zu kennzeichnenden Teile bewegt, sodaß das Prägerad 2 ca. 10 mm oberhalb der zu kennzeichnenden Oberfläche, in Abhängigkeit von den zu kennzeichnenden Teilen und der davon abhängigen Voreinstellung durch den hydraulischen Antrieb 11, angehalten wird.Immediately before the marking process to be carried out, the stamping unit 8 is moved vertically above the parts to be marked via a further hydraulic drive 13, which is used for fine adjustment of the stamping unit, so that the stamping wheel 2 is approximately 10 mm above the surface to be marked, depending on the parts to be labeled and the presetting dependent on it by the hydraulic drive 11, is stopped.
Anschließend wird das in der Prägeeinheit 8 drehbar gelagerte Prägerad 2, an dessen Umfang in einem Teilsegment zumindest ein Zeichenträger, in diesem Beispiel mehrere Zeichenträger, welche Zeichen tragen, eingesetzt sind, synchron zur Geschwindigkeit der sich auf dem Rollgang 1 bewegenden, zu kennzeichnenden Teile mit Hilfe des Antriebes 15 beschleunigt. Dabei werden gegebenenfalls auch Geschwindigkeitsänderungen der am Rollgang 1 laufenden Teile berücksichtigt.The embossing wheel 2, which is rotatably mounted in the embossing unit 8 and on whose circumference at least one character carrier, in this example a plurality of character carriers which carry characters, is inserted in a sub-segment, is synchronized with the speed of the parts to be identified which are moving on the roller table 1 Accelerated using the drive 15. If necessary, speed changes of the parts running on the roller table 1 are also taken into account.
Nach einer teilweisen Beschleunigung des Prägerades 2 über den parallel zur Drehachse des Prägerades 2 gelagerten Antrieb 15 kommt es infolge der Exzentrizität des Prägerades 2 zu einer Berührung zwischen dem Prägerad und den sich am Rollgang 1 bewegenden Teilen, wobei die Berührung unmittelbar vor dem im Umfang des Prägerades 2 eingesetzten Zeichenträgem erfolgt.After a partial acceleration of the embossing wheel 2 via the drive 15 mounted parallel to the axis of rotation of the embossing wheel 2, the eccentricity of the embossing wheel 2 occurs a contact between the embossing wheel and the parts moving on the roller table 1, the contact taking place immediately in front of the character carrier used in the circumference of the embossing wheel 2.
Die dabei vom jeweils zu kennzeichnenden Teil auf das Prägerad 2 ausgeübte Kraft bewirkt ein Hochheben der in einem Führungssystem 14 beweglich aufgehängten Prägeeinheit 8. Über den hydraulischen Antrieb 13 wird dieser Kraft entgegengeregelt, sodaß die Kennzeichnung der Teile mit einer konstanten und für die jeweiligen Teile einstellbaren Kraft erfolgt, indem das Prägerad 2 mit den darin eingesetzten Zeichenträgem mit dieser konstanten Kraft über den zu kennzeichnenden Teil rollt.The force exerted on the embossing wheel 2 by the part to be identified in each case causes the embossing unit 8, which is movably suspended in a guide system 14, to be lifted. This force is counteracted by means of the hydraulic drive 13, so that the identification of the parts with a constant and adjustable for the respective parts Force occurs when the embossing wheel 2 with the character carriers used therein rolls with this constant force over the part to be marked.
Die Kennzeichnung der Teile kann dabei in verschiedenen oder gleichen Abständen erfolgen, wobei die jeweiligen Abstände frei einstellbar sind.The parts can be marked at different or the same intervals, the respective intervals being freely adjustable.
Nach diesem Kennzeichnungsvorgang entfernt sich das Prägerad 2 aufgrund seiner Exzentrizität wieder von dem gekennzeichneten Teil.After this marking process, the embossing wheel 2 moves away from the marked part due to its eccentricity.
Das Prägerad 2 wird jetzt wahlweise abgebremst oder dreht mit der zur Laufgeschwindigkeit der zu kennzeichnenden Teile synchronen Umfangsgeschwindigkeit weiter, und die Kennzeichnung der Teile kann, wie oben beschrieben, wiederholt werden. Dabei kann derselbe Teil an einer anderen Stelle nochmals gekennzeichnet werden, oder ein anderer, sich auf dem Rollgang bewegender Teil wird gekennzeichnet.The embossing wheel 2 is now either braked or rotated at the circumferential speed synchronized with the running speed of the parts to be marked, and the marking of the parts can be repeated as described above. The same part can be marked again at a different location, or a different part moving on the roller table is marked.
Nachdem ein zu kennzeichnender Teil durch die Vorrichtung gelaufen ist, können anschließend wahlweise alle Antriebe in deren Referenz- oder Grundposition bewegt werden, sie können aber auch in der momentan eingenommenen Position verweilen, oder in einer neuen Vorposition - gegebenenfalls für einen neuen zu kennzeichnenden Teil - positioniert werden, und der Kennzeichnungsvorgang kann wieder für einen gleichen oder anderen Teil vorgenommen werden.After a part to be marked has passed through the device, all drives can then optionally be moved into their reference or basic position, but they can also remain in the position currently occupied, or in a new preposition - if necessary for a new part to be marked. can be positioned, and the marking process can be carried out again for an identical or different part.
Zum Wechseln von einem oder mehreren im Prägerad eingesetzten Zeichenträgem stehen im wesentlichen zwei Wechselmechanismen zur Verfügung. Zum Wechseln von einzelnen, speziell aber mehreren in dem Prägerad eingesetzten Zeichenträger ist im allgemeinen ein Zeichenträ- gerwechselmechanismus, wie er aus einer Parallelanmeldung (ungarische Anmeldenummer P 97 02 364) bekannt ist, angeschlossen. Dabei wird das in der Prägeeinheit gelagerte Prägerad in unmittelbar Nähe eines Zeichenträgermagazins so verschwenkt, daß ein Austauschen von Zeichenträgem des Prägerades gegen solche aus dem Zeichenträgermagazin und vice versa ermöglicht ist. Besonders für das Wechseln eines einzelnen Zeichenträgers, wobei die Dauer für einen solchen Wechselvorgang im Bereich von einer Sekunde liegt, eignet sich ein sogenannter Einzelzei- chenträgerwechselmechanismus, der im Inneren des Prägerades 2 integriert ist. Ein solcher Mechanismus ist ebenfalls in einer Parallelanmeldung (ungarische Anmeldemummer P 98 00 579) beschrieben. There are essentially two change mechanisms available for changing one or more character carriers used in the embossing wheel. To change individual, but especially several, character carriers used in the embossing wheel, a character carrier changing mechanism, as is known from a parallel application (Hungarian application number P 97 02 364), is generally connected. The embossing wheel stored in the embossing unit is pivoted in the immediate vicinity of a character carrier magazine in such a way that it is possible to exchange character carriers of the embossing wheel for those from the character carrier magazine and vice versa. A so-called single character carrier change mechanism, which is integrated in the inside of the embossing wheel 2, is particularly suitable for changing an individual character carrier, the duration for such a change process being in the range of one second. Such a mechanism is also described in a parallel application (Hungarian application number P 98 00 579).
