Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Bündeln von Stangen, Rohren, Profilen und anderen länglichen Gegenständen.The invention relates to a method and an apparatus for bundling rods, tubes, profiles and other elongated objects.

Gepreßte bzw. anschließend blankgezogene Profile werden üblicherweise in abgelängtem Zustand zu handlichen Bündeln verpackt, zum Verbraucher transportiert. Wesentlich bei diesem Transport ist, daß insbesondere, wenn blankgezogene Profile versandt werden sollen, jedes einzelne Profil in Längsrichtung unverschieblich in dem Bündel gehalten ist, da es ansonsten zu unerwünschten Beschädigungen der Oberfläche bzw. zur Kaltverschweißung neigenden Metallen zu Kaltschweißverbindungen kommt.Pressed or subsequently drawn profiles are usually packed into handy bundles in the cut state and transported to the consumer. It is essential in this transport that, in particular if bright-drawn profiles are to be shipped, each individual profile is held immovably in the bundle in the longitudinal direction, since otherwise undesirable damage to the surface or metals prone to cold welding result in cold welded connections.

Zur Lösung dieser Probleme hat man um die Bündel in bestimmtem Abstand zueinander mehrere Windungen Klebeband mit Papierunterlage aufgebracht. Eine andere Arbeitsweise sah vor, in bestimmtem axialen Abstand Haltebänder aus Kunststoff durch Umwickeln aufzubringen. Beiden Lösungen ist gemeinsam, daß sie entweder sehr lohnintensiv sind oder aber aufwendige Maschinen erforderlich sind und daß sie sich schlecht in einen kontinuierlich ablaufenden Arbeitsprozeß wirtschaftlich integrieren lassen. Darüber hinaus sind die relativ dünnen Klebebänder bzw. Kunststoffbänder anfällig gegen Beschädigung.To solve these problems, several turns of adhesive tape with paper backing have been applied around the bundles at a certain distance from one another. Another way of working envisaged applying plastic holding straps at a certain axial distance by wrapping them around. Both solutions have in common that they are either very cost-intensive or that expensive machines are required and that they are difficult to integrate economically into a continuously running work process. In addition, the relatively thin adhesive tapes or plastic tapes are susceptible to damage.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, mit dem es möglich ist, Stangen, Rohre, Profile etc. in einem kontinuierlichen Arbeitsprozeß in wirtschaftlicher Weise zu bündeln, und zwar so, daß jede Stange, jedes Rohr bzw. jedes Profil in längsaxialer Richtung unverschieblich in dem Bündel gehalten ist und daß die das Bündel zusammenhaltenden Mittel nahezu unempfindlich gegen mechanische Beschädigung sind, sich aber dennoch vom Verbraucher der Stangen mittels Werkzeug leicht auftrennen lassen.The invention has for its object to provide a method with which it is possible to bundle rods, tubes, profiles, etc. in a continuous work process in an economical manner, in such a way that each rod, each tube or profile in a longitudinal axial Direction is held immovably in the bundle and that the means holding the bundle together are almost insensitive to mechanical damage, but can nevertheless be easily separated by the consumer of the rods using a tool.

Diese Aufgabe wird dadurch gelöst, daß mindestens zwei Ringe aus einem federelastischen Material auf einem Dorn auseinandergespreizt werden, daß die vorgebündelten Stangen, Rohre, Profile etc. durch die Öffnung der Ringe hindurchgeführt bzw. die Ringe in gespreiztem Zustand die vorgebündelten Stangen, Rohre, Profile etc. umgebend in längsaxialer Richtung bewegt werden und daß in vorbestimmten Abständen jeweils ein Ring von dem Dorn abgezogen und dabei um das Bündel gespannt wird. Mit besonderem Vorteil lassen sich bei diesem Verfahren Ringe aus einem gummielastischen Werkstoff verwenden. Das genannte Material weist eine hohe Dehnung auf und läßt sich aus diesem Grunde ohne Beschädigung auseinanderspreizen. Es sollten Ringe mit einem in Richtung ihrer Längsachse abgeflachten Wandungsquerschnitt verwendet werden. Dies hat den Vorteil, daß die Ringe, die eine Einwegverpackung darstellen, relativ preiswert auf dem Markt erhältlich sind. Ein weiterer Vorteil ist darin zu sehen, daß die Ringe relativ unbeweglich auf dem Bündel lagern. Damit sich die Ringe von dem Dorn leicht abziehen lassen, hat es sich als vorteilhaft erwiesen, die Ringe zumindest im Bereich ihrer Innenbohrung mit einem Gleitmittel, wie beispielsweise Talkumpuder, zu beschichten. Eine weitere ebenfalls vorteilhafte Lösung besteht darin, Ringe mit einem runden Wandungsquerschnitt zu verwenden. Diese Ringe lassen sich ohne weitere Hilfsmittel leicht von dem Dorn abstreifen und bringen noch den Vorteil mit sich, daß sie bei Krafteinwirkung auf der Oberfläche des Bündels in längsaxialer Richtung abrollen können und damit einer mechanischen Beschädigung der Ringe vorbeugen. Um die durch die vorgespannten Ringe aufgebrachte Kraft möglichst gleichmäßig über die Länge des Bündels zu verteilen, hat es sich als zweckmäßig erwiesen, die Ringe mit gleichem axialen Abstand zueinander auf das Bündel aufzuspannen. Werden die auf dem gespreizten Dorn befindlichen Ringe von einer den Dorn umgebenden Abstreifvorrichtung für die Ringe abgezogen, hat es sich als zweckmäßig erwiesen, daß jeweils ein Ring durch Verschiebung des Domes und/oder der Abstreifvorrichtung gegeneinander von dem Dorn abgezogen wird. Diese Arbeitsweise ermöglicht eine nahezu beschädigungsfreie Aufbringung der Ringe auf das Bündel. Da sich zweckmäßigerweise mehrere Ringe gleichzeitig auf dem Dorn befinden, ist es vorteilhaft, wenn alle auf dem Dorn befindlichen Ringe während des Abstreifvorgangs um den gleichen Weg und in der gleichen Richtung wie der abzustreifende Ring verschoben werden. Lediglich ein Ring rutscht dabei von dem Dorn ab.This object is achieved in that at least two rings made of a resilient material are spread apart on a mandrel, that the pre-bundled rods, tubes, profiles etc. are passed through the opening of the rings or the rings in the spread state the pre-bundled rods, tubes, profiles etc. are moved in the longitudinal axial direction surrounding and that a ring is pulled off the mandrel at predetermined intervals and thereby stretched around the bundle. Rings made of a rubber-elastic material can be used with particular advantage in this process. The material mentioned has a high elongation and can therefore be spread apart without damage. Rings with a wall cross-section flattened in the direction of their longitudinal axis should be used. This has the advantage that the rings, which are disposable packaging, are relatively cheaply available on the market. Another advantage is that the rings are relatively immobile on the bundle. So that the rings can be easily removed from the mandrel, it has proven to be advantageous to coat the rings with a lubricant, for example talcum powder, at least in the region of their inner bore. Another equally advantageous solution is to use rings with a round wall cross section. These rings can be easily stripped from the mandrel without further aids and have the further advantage that they can roll on the surface of the bundle in the axial direction in the event of force and thus prevent mechanical damage to the rings. In order to distribute the force exerted by the prestressed rings as evenly as possible over the length of the bundle, it has proven to be expedient to clamp the rings onto the bundle with the same axial distance from one another. If the rings located on the expanded mandrel are pulled off by a stripping device for the rings surrounding the mandrel, it has proven to be expedient for one ring in each case to be pulled off the mandrel by displacing the mandrel and / or the stripping device. This method of operation enables the rings to be applied to the bundle with virtually no damage. Since there are expediently a plurality of rings on the mandrel at the same time, it is advantageous if all the rings on the mandrel are displaced by the same path and in the same direction as the ring to be stripped off during the stripping process. Only a ring slips off the mandrel.

Zur Durchführung des Verfahrens gemäß der Lehre der Erfindung hat sich eine Vorrichtung als zweckmäßig erwiesen, bei der zwei koaxial zueinander angeordnete Ringscheiben mit einer zentrischen Bohrung zum Durchführen des Bündels vorgesehen sind, die durch mindestens drei Schrauben miteinander verbunden sind, wobei die Schrauben in der einen Ringscheibe, die drehbar ist, in Längslöchern geführt sind. Zwischen den Scheiben sind mindestens drei Segmente im gleichen Abstand zur Bohrung angeordnet, die über in entsprechenden unter einem Winkel zur Radialen verlaufenden Langlöchern geführte Stifte in Richtung der Langlöcher bei Drehung der drehbaren Ringscheibe bewegbar sind. Jedes Segment weist eine in axialer Richtung verlaufende Klaue auf, deren Länge mindestens der Summe der einzelnen Breiten der Ringe entspricht. Weiterhin ist eine die Klauen konzentrisch umgebende Abstreifvorrichtung vorgesehen. Die Ringscheiben und/oder diese Abstreifvorrichtung sind gegeneinander in längsaxialer Richtung verschiebbar. Als besonders günstig hat sich bei einer derartigen Vorrichtung erwiesen, daß die Abstreifvorrichtung fest und die Ringscheiben über einen Hydraulikzylinder antreibbar sind. Auch die drehbare Ringscheibe sollte über einen Hydraulikzylinder antreibbar sein. Die Abstreifvorrichtung besteht zweckmäßigerweise aus einem Rohrstück, in dessen Innenwandung Abstreifringe mit unterschiedlichen Innendurchmessern eingearbeitet sind, die in Richtung auf die Ringscheiben zunehmen. Diese Version gestattet, bei entsprechender Hubeinstellung, daß lediglich ein Ring abgezogen wird, während die anderen Ringe um den gleichen Wert in der gleichen Richtung transportiert werden. Um diesen Vorgang zu vereinfachen, sind die Klauen an ihrer äußeren die Ringe aufnehmenden Oberfläche entsprechend den Abstreifringen gestuft ausgebildet.To carry out the method according to the teaching of the invention, a device has proven to be expedient, in which two coaxial ring disks are provided with a central bore for the passage of the bundle, which are connected to one another by at least three screws, the screws in one Washer, which is rotatable, are guided in longitudinal holes. At least three segments are arranged between the disks at the same distance from the bore and can be moved in the direction of the elongated holes by rotating the rotatable annular disk via pins guided in corresponding elongated holes at an angle to the radial. Each segment has an axially extending claw, the length of which corresponds at least to the sum of the individual widths of the rings. Furthermore, a stripping device concentrically surrounding the claws is provided. The ring disks and / or this stripping device can be displaced relative to one another in the longitudinal axial direction. In a device of this type, it has proven particularly favorable that the stripping device is fixed and the ring disks can be driven via a hydraulic cylinder. The rotating ring disk should also be drivable via a hydraulic cylinder. The stripping device expediently consists of a piece of pipe, in the inner wall of which stripping rings with different inner diameters are incorporated, which increase in the direction of the ring disks. With the appropriate stroke setting, this version allows only one ring to be pulled off, while the other rings are transported by the same value in the same direction. In order to simplify this process, the claws are designed in a stepped manner on their outer surface receiving the rings in accordance with the wiper rings.

Die Erfindung ist anhand der in den Figuren 1 bis 8 schematisch dargestellten Ausführungsbeispiele näher erläutert.The invention is explained in more detail with reference to the exemplary embodiments shown schematically in FIGS. 1 to 8.

Die auf einer nicht dargestellten Zieh- oder Richtmaschine verarbeiteten Rohre 1 werden mittels eines nicht dargestellten Krans auf einen Rütteltisch 2 abgelegt. Der Rütteltisch 2 vereinzelt über die Vibratoren 3 die Rohre, so daß diese in eine Kipprinne 4, die auf einer Waage 5 installiert ist, fallen. Der Vibrationstisch 2 wird über einen einstellbaren Gewichtskontakt abgeschaltet. Die Kipprinne 4 übergibt die zu bündelnden Rohre 1 auf eine V-förmige Rollenbahn 6. Mit einem angetriebenen Bundschieber 7 werden die Rohre 1 durch eine später näher beschriebene Bündelzange 8 geschoben, die auf die gebündelten Rohre 1 in bestimmtem längsaxialen Abstand Gummiringe aufbringt. Hinter der Bündelzange 8 wird das Bündel 9 auf ein unterbrochenes Förderband 10 gegen den Anschlag 11 gefördert. Mittels der Auswerfer 12 wird das Bündel 9 in eine V-Rinne 13 gelegt und mit den Zylindern 14 und 15 stirnseitig gerade gestoßen. Ein weiterer Auswerfer 16 hebt das Bündel 9 in eine auf einer Waage 17 installierte Sammelrunge 18 oder eine Kiste.The tubes 1 processed on a drawing or straightening machine, not shown, are placed on a vibrating table 2 by means of a crane, not shown. The vibrating table 2 separates the tubes via the vibrators 3, so that they fall into a tipping channel 4, which is installed on a scale 5. The vibrating table 2 is switched off via an adjustable weight contact. The tipping channel 4 transfers the tubes 1 to be bundled to a V-shaped roller conveyor 6. With a driven collar slide 7, the tubes 1 are pushed through a bundle pliers 8 which will be described in more detail later and which applies rubber rings to the bundled tubes 1 at a certain axial distance. Behind the bundle tongs 8, the bundle 9 is conveyed onto an interrupted conveyor belt 10 against the stop 11. By means of the ejector 12, the bundle 9 is placed in a V-groove 13 and the cylinders 14 and 15 are just pushed against the end face. Another ejector 16 lifts the bundle 9 into a collecting stanchion 18 or a box installed on a scale 17.

Die Bündelzange 8 besteht im wesentlichen aus zwei Ringscheiben 19 und 20, die über Schrauben 21 gegeneinander geführt sind. Während die Ringscheibe 19 fest installiert ist, ist die Ringscheibe 20 drehbar, wobei die Schäfte der Schrauben 21 in den Längslöchern 22 geführt werden. Zwischen den beiden Ringscheiben 19 und 20 sind mehrere Segmente 23 angeordnet, die je eine Klaue 24 tragen. In der Ringscheibe 20 sind unter einem Winkel zur Radialen verlaufende Längsschlitze 25 eingebracht, in die an jedem Segment 23 befestigte Stifte 26 eingreifen, so daß sich bei Drehung der Ringscheibe 20 die Segmente gleichmäßig in Richtung der Langlöcher 25 bewegen. Die Drehung der Ringscheibe 20 geschieht über einen Hydraulikzylinder 27, der über den Arm 28 mit der Ringscheibe 19 und über den Arm 29 mit der Ringscheibe 20 verbunden ist. Bei Betätigung des Hydraulikzylinders 27 verändert sich also der Abstand zwischen den einzelnen Segmenten 23 und damit auch zwischen den einzelnen Klauen 24. Die Klauen 24 sind von einem Rohrstück 30 umgeben, in dessen Innenwandung Abstreifringe 31 eingearbeitet sind. Die Steghöhe der Abstreifringe 31 ist unterschiedlich und nimmt in Richtung auf die Ringscheibe 19 ab. In die Klauen 24 sind entsprechende Absätze 32 eingearbeitet. Auf die Klauen 24 werden Gummiringe 33 in einer Anzahl aufgesteckt, die für die Halterung der Rohre 1 zu einem Bündel 9 erforderlich ist. Während ein Bündel 9 den Innenraum der Bündelzange 8 durchläuft, wird zu vorbestimmten Zeitpunkten die Bündelzange über nicht dargestellte Hydraulikzylinder in Gegenrichtung zur Bewegungsrichtung des Bündels 9 um einen Wert bewegt, der mindestens der Ausdehnung der Ringe 33 in Durchlaufrichtung der Bündel 9 entspricht. Dabei wird der auf dem letzten Absatz 32 der Klaue 24 befindliche Ring 33 abgestreift und spannt sich auf das Bündel 9. Die Kontaktauslösung für die Hubverstellung für die Bündelzange erfolgt durch Anfahren von nicht dargestellten Endschaltern des in der Figur 2 dargestellten Bundschiebers. Sind alle Ringe 33 auf das entsprechende Bündel 9 aufgebracht, wird die Bündelzange wieder in ihre Ausgangslage zurücktransportiert und dabei die Klauen 24 einander angenähert und neue Ringe 33 aufgesteckt.The bundle pliers 8 essentially consist of two washers 19 and 20 which are guided against one another by screws 21. While the washer 19 is permanently installed, the washer 20 is rotatable, the shafts of the screws 21 being guided in the longitudinal holes 22. A plurality of segments 23 are arranged between the two annular disks 19 and 20, each of which carries a claw 24. In the annular disc 20 are at an angle to the radial longitudinal slots 25 are introduced, engage in the attached to each segment 23 pins 26, so that the segments move evenly in the direction of the elongated holes 25 when the ring disc 20 is rotated. The rotation of the ring disk 20 takes place via a hydraulic cylinder 27 which is connected to the ring disk 19 via the arm 28 and to the ring disk 20 via the arm 29. When the hydraulic cylinder 27 is actuated, the distance between the individual segments 23 and thus also between the individual claws 24 changes. The claws 24 are surrounded by a tube piece 30, in the inner wall of which wiper rings 31 are incorporated. The web height of the scraper rings 31 is different and decreases in the direction of the ring disk 19. Corresponding paragraphs 32 are incorporated into the claws 24. A number of rubber rings 33 are attached to the claws 24, which are required for holding the tubes 1 in a bundle 9. While a bundle 9 passes through the interior of the bundle tongs 8, the bundle tongs are moved at predetermined times via hydraulic cylinders (not shown) in the opposite direction to the direction of movement of the bundle 9 by a value which corresponds at least to the extent of the rings 33 in the direction of travel of the bundles 9. The ring 33 located on the last step 32 of the claw 24 is stripped off and clamps onto the bundle 9. The triggering of the contact for the stroke adjustment for the bundle pliers takes place by approaching limit switches, not shown, of the collar slide shown in FIG. Once all the rings 33 have been applied to the corresponding bundle 9, the bundle pliers are transported back to their starting position and the claws 24 are brought closer to one another and new rings 33 are attached.

Die Ringe 33, die in ihrem Wandungsquerschnitt rechtwinklig ausgebildet sind, aber auch kreisrund sein können, tragen an ihrer mit den Klauen 24 in Berührung stehenden Innenwandung eine dünne Talkumschicht, um den Abstreifvorgang zu erleichtern.The rings 33, which are rectangular in their wall cross section but can also be circular, have a thin talcum layer on their inner wall in contact with the claws 24 in order to facilitate the stripping process.

Die Figuren 7 und 8 zeigen ein fertiges Bündel 9, mit den darauf befindlichen Gummiringen 33.FIGS. 7 and 8 show a finished bundle 9 with the rubber rings 33 located thereon.
