Description

Verfahren und Vorrichtung zum Wechseln von Bandrollen an vorzugsweise offenen Transportbandanlagen Method and apparatus for changing rolls of tape preferably open conveyor belt systems
Beschreibung:Description:
Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Wechseln von Bandrollen an vorzugsweise offenen Transportbandanlagen gemäß Patentanspruch 1 und 3.The invention relates to a method and a device for changing rolls of tape preferably open conveyor belt systems according to claim 1 and 3.
Unter offenen Transportbandanlagen werden solche Anlagen verstanden, die keine Rollgutförderer sind, sondern fest montierte Bandrollen und/oder Rollenstühle zur Unterstützung und Formung des Transportbandes verwenden. Derartige Transportbandanlagen sind häufig viele Kilometer lang und müssen möglichst kontinuierlich betrieben werden. Die das Transportband tragenden Bandrollen dieser Transportbandanlagen sind Verschleiß und Beschädigungen ausgesetzt und müssen zu unvorhergesehenen Zeitpunkten an nicht vorhersagbaren Stellen ausgetauscht oder repariert werden. Für die Dauer des Austausches muss bisher die Transportbandanlage still gesetzt werden. Der Produktivitätsausfall wiegt dabei um so schwerer, je länger die Transportbandanlage ist.Open conveyor belt systems are understood to mean systems which are not roller conveyors, but use permanently installed belt rollers and / or wheelchairs to support and shape the conveyor belt. Such conveyor belts are often many kilometers long and must be operated as continuously as possible. The belt rolls of these conveyor belts carrying the conveyor belt are subject to wear and damage and must be replaced or repaired at unpredictable times at unpredictable points. For the duration of the exchange so far the conveyor belt system must be shut down. The productivity loss weighs the heavier the longer the conveyor belt system is.
Der Erfindung liegt daher die Aufgrabe zu Grunde, ein Verfahren und auch eine Vorrichtung vorzuschlagen, bei dem bzw. bei der ein schnellerer Bandrollenwechsel auch ohne Anlagenstillsetzung erfolgen kann.The invention is therefore based on the Aufgrabe to propose a method and a device in which or in which a faster roll change can also be done without plant quenching.
Die Lösung dieser Aufgabe ist in den Ansprüchen 1 und 3 angegeben. Die Unteransprüche 2 und 4 - 12 enthalten sinnvolle ergänzende Verfahrensvorschläge und Ausführungsbeispiele.The solution to this problem is specified in claims 1 and 3. The dependent claims 2 and 4 - 12 contain useful additional procedural suggestions and embodiments.
Erfindungsgemäß wird vorgeschlagen, dass an der Stelle, an der Bandrollen auszutauschen sind, das Transportband für die kurze Dauer dieser Arbeit mit Hilfe einer Vorrichtung angehoben wird. Dazu werden während des laufenden Betriebes seitlich, jeweils links und rechts des Transportbandes auf Schwenkarmen oder ähnlichen Vorrichtungen angeordnete Stützrollen unter das jeweilige Transportband bewegt, um dann mit Hilfe dieser Stützrollen das Band anzuheben und so den Kontakt zu den laufenden Bandrollen des Transportbandes in unmittelbarer Umgebung zu trennen. Zum Schutz des Personals wird der Montagebereich mit vorübergehend einbringbaren Schutzelementen, vorzugsweise oben und/oder unten und seitlich gegen die Berührung des laufenden Transportbandes und der weiterhin laufenden benachbarten Bandrollen abgeschirmt. Nach Tausch oder Reparatur der jeweiligen Bandrollen werden die Schutzelemente aus dem Montagebereich entfernt und die Stützrollen abgesenkt und ebenfalls aus dem Montagebereich entfernt. Die Vorrichtung zum Wechseln und die Schutzelemente werden danach zum nächsten Reparaturort transportiert oder eingelagert.According to the invention, it is proposed that at the point where the reels are to be exchanged, the conveyor belt is lifted for the short duration of this work by means of a device. For this purpose, during operation, side, respectively left and right of the conveyor belt on pivot arms or similar devices arranged support rollers under the respective Moved conveyor belt, then with the help of these support rollers to raise the band and so to separate the contact with the current tape rolls of the conveyor belt in the immediate vicinity. To protect the personnel of the mounting area is temporarily shielded protective elements, preferably above and / or below and shielded laterally against the contact of the moving conveyor belt and the ongoing running adjacent rolls of tape. After replacement or repair of the respective rolls of tape, the protective elements are removed from the mounting area and lowered the support rollers and also removed from the mounting area. The device for changing and the protective elements are then transported to the next repair or stored.
Die erfindungsgemäße Vorrichtung zum Wechseln von Bandrollen besteht aus einer die Transportbandanlage überspannenden Portaleinheit, die etwas breiter ist als die Transportbandanlage und so konzipiert ist, dass sie über die Transportbandanlage gestülpt oder umspannend angeordnet werden kann. Diese Portaleinheit ist vorzugsweise in Längsrichtung der Transportanlage auf Schienen verfahrbar oder so gestaltet, dass sie jederzeit angehoben, auf einem Transportfahrzeug verfrachtet und wieder über die Transportanlage an der Stelle, an der sie benötigt wird, platziert werden kann. Falls erforderlich stabilisieren entsprechende Sicherungseinrichtungen die Standfestigkeit der Portaleinheit. Die Füße der Portaleinheit können so gestaltet sein, dass sie individuell höhenverstellbar sind und mit der Stützkonstruktion der Transportbandanlage verbindbar sind.The device according to the invention for changing reels consists of a conveyor unit spanning portal unit, which is slightly wider than the conveyor belt system and is designed so that it can be placed over the conveyor belt system or arranged spanning. This portal unit is preferably movable in the longitudinal direction of the transport system on rails or designed so that they can be lifted at any time, shipped on a transport vehicle and placed back on the transport system at the point where it is needed. If necessary, appropriate security devices stabilize the stability of the portal unit. The feet of the portal unit can be designed so that they are individually adjustable in height and can be connected to the support structure of the conveyor belt system.
An den senkrechten Stützen der Portaleinheit sind auf beiden Seiten des Transportbandes Schwenkarme installiert, die um mindestens 90° um eine senkrechte oder im Wesentlichen senkrechte Schwenkachse schwenkbar sind. An diesen Schwenkarmen sind Stützrollen befestigt, die in Form, Größe und Lage den in der Transportbandanlage installierten Bandrollen jeweils für den Ober- und Untertrum entsprechen. Ferner sind sie so eingestellt, dass sie auch der Querschnittsverformung des Transportbandes und damit der exakten Ausrichtung der Bandrollen entsprechen. Die Schwenkarme sind gemeinsam oder auch einzeln mit einer Hubvorrichtung anhebbar und absenkbar.At the vertical supports of the portal unit pivot arms are installed on both sides of the conveyor belt, which are pivotable by at least 90 ° about a vertical or substantially vertical pivot axis. On these swivel arms support rollers are fixed, which correspond in shape, size and position installed in the conveyor belt reel for each of the upper and lower run. Furthermore, they are adjusted so that they also correspond to the cross-sectional deformation of the conveyor belt and thus the exact alignment of the rolls of tape. The pivot arms can be raised and lowered together or individually with a lifting device.
Die Hub- und die Schwenkbewegungen können manuell oder auf alle bekannten Arten mechanisiert erfolgen und sensorisch überwacht und gesteuert sein.The lifting and pivoting movements can be done manually or in any known manner mechanized and be monitored and controlled sensor.

In Fig. 1 ist die Transportbandanlage 1 innerhalb der Stützkonstruktion 9 dargestellt, wobei insbesondere zur Versteifung in Fig. 2 auch Querstege 25 und Fußbalken 26 dargestellt sind. Innerhalb dieser Stützkonstruktion 9 bewegen sich das üblicherweise als Obertrum bezeichnete obere Transportband 2 und das üblicherweise als Untertrum bezeichnete untere Transportband 3 in entgegengesetzten Richtungen, wobei das obere Transportband der Materialförderung dient. Das obere Transportband 2 wird von den beiden seitlichen Bandrollen 4 und 5 und der Mittelrolle 6 geführt, während das untere Transportband 3 von den beiden Bandrollen 7 und 8 geführt wird. Die Befestigung der Bandrolle 4 - 8 an der Stützkonstruktion 9 ist nicht mehr dargestellt, da sie in an sich bekannter Weise erfolgt. Die erfindungsgemäße Portaleinheit 10 ist über die Transportanlage 1 gestülpt, besteht im Wesentlichen aus den senkrechten Stützen 11 und dem oberen Übergang 23 und besitzt höhenverstellbare Füße 21, die auch insbesondere mit den Fußbalken 26 der Stützkonstruktion 9 verbindbar sind. An den senkrechten Stutzen 11 sind Führungsschienen 19 nur schematisch dargestellt, die ebenfalls im Wesentlichen senkrecht verlaufen. In diesen Führungsschienen 19 können mit Hilfe einer an sich bekannten Hubvorrichtung 20 die Schwenkarme 12, 13 verstellt werden. Die Schwenkarme 12, 13 besitzen senkrechte Teile 12a, 13a, die in den Führungsschienen 19 hohenverstellbar und um eine im Wesentlichen senkrechte Drehachse drehbar sind. Mit den senkrechten Teilen 12a, 13a, sind Rollenhalter 12b, 12c, 13b für die Stutzrollen 14 - 18 verbunden. Die Schwenkarme 12, 13 lassen sich jeweils nach innen in den Transportbandbereich unter das obere Transportband 2 oder das untere Transportband 3 schwenken. Das Schwenken kann manuell oder mechanisch unterstutzt erfolgen. Die Endposition ist erreicht, wenn die eingeschwenkten Schwenkarme 12, 13 mit ihren daran befestigten Stutzrollen 14 - 18 parallel zu den Bandrollen 4 - 8 angeordnet sind. Dabei sind die Stutzrollen 14 - 18 in Bandlangsnchtung horizontal versetzt zu den Bandrollen 4 - 8 angeordnet, damit sie bei der Vertikalbewegung an diesen Bandrollen 4 - 8 vorbei bewegt werden können. Auf der linken und rechten Seite der Portaleinheit 10 ist jeweils mindestens ein Schwenkarm 12, 13 für das obere Transportband 2 und das untere Transportband 3 angeordnet. Für das obere Transportband 2 bedeutet das, dass auf einer Seite eine seitliche schräg angeordnete Stutzrolle 14 auf einem Rollenhalter 12b und eine waagerecht angeordnete mittlere Stutzrolle 16 auf einem mit dem Rollenhalter 12b verbundenen Rollenhalter 12c angeordnet ist. Auf der anderen Seite ist dann nur eine Stutzrolle 15 auf einem entsprechend schräg angeordneten Rollenhalter befestigt. Da bei dem unteren Transportband 3 auf eine Mittelrolle verzichtet werden kann, ist auf jeder Seite an einen Rollenhalter 13b eine schräg angeordnete Stutzrolle 17, 18 angeordnet. Die Rollenhalter 12b, 12c bzw. 13b können in der eingeschwenkten Position jeweils in geeigneter Weise miteinander verriegelt werden bevor sie gemeinsam in vertikaler Richtung bewegt werden.In Fig. 1, the conveyor belt system 1 is shown within the support structure 9, wherein in particular for stiffening in Fig. 2 and transverse webs 25 and foot bar 26 are shown. Within this support structure 9, the upper conveyor belt 2, usually referred to as the upper run, and the lower conveyor belt 3, usually referred to as the lower run, move in opposite directions, the upper conveyor belt serving to convey the material. The upper conveyor belt 2 is guided by the two lateral belt rollers 4 and 5 and the center roller 6, while the lower conveyor belt 3 is guided by the two belt rollers 7 and 8. The attachment of the roll of tape 4 - 8 on the support structure 9 is no longer shown, since it takes place in a conventional manner. The portal unit 10 according to the invention is placed over the transport system 1, consists essentially of the vertical supports 11 and the upper transition 23 and has height-adjustable feet 21, which also in particular with the foot bar 26 of the support structure 9 connectable are. On the vertical nozzle 11 guide rails 19 are shown only schematically, which also extend substantially vertically. In these guide rails 19, the pivot arms 12, 13 can be adjusted by means of a known lifting device 20. The pivot arms 12, 13 have vertical parts 12a, 13a, which are vertically adjustable in the guide rails 19 and about a substantially vertical axis of rotation. With the vertical parts 12a, 13a, roller holders 12b, 12c, 13b are connected to the support rollers 14-18. The pivot arms 12, 13 can each be pivoted inwardly in the conveyor belt area under the upper conveyor belt 2 or the lower conveyor belt 3. The pivoting can be done manually or mechanically assisted. The end position is reached when the pivoted pivot arms 12, 13 are arranged with their attached support rollers 14 - 18 parallel to the tape rolls 4-8. The support rollers 14 - 18 in Bandlangsnchtung horizontally offset from the tape reels 4 - 8 are arranged so that they can be moved in the vertical movement of these tape rolls 4 - 8 over. At least one pivot arm 12, 13 for the upper conveyor belt 2 and the lower conveyor belt 3 are arranged on the left and right sides of the portal unit 10. For the upper conveyor belt 2, this means that a side obliquely arranged stub roll 14 on one side is arranged on a roll holder 12b and a horizontally arranged central stub roll 16 is mounted on a roll holder 12c connected to the roll holder 12b. On the other hand, only one support roller 15 is mounted on a correspondingly inclined roller holder. Since in the lower conveyor belt 3 can be dispensed with a central role, an obliquely arranged Abutzrolle 17, 18 is arranged on each side of a roller holder 13b. The roller holders 12b, 12c and 13b can be locked together in the pivoted position in a suitable manner before they are moved together in the vertical direction.
In der oberen Position der Stutzrollen 14 - 16 und des Transportbandes 2 nach Fig. 2 und 4 sind in dem Montagebereich sowohl unterhalb des angehobenen oberen Transportbandes 2 als auch oberhalb des unteren Transportbandes 3 stabile Plattenelemente als Schutzelemente 22 dargestellt, die insbesondere mit den Querstegen 25 und den senkrechten Stutzen der Stutzkonstruktion 9 leicht lösbar verbunden sind. Der Bereich zwischen dem oberen und unteren Schutzelement 22 ist dann für das Montagepersonal soweit erforderlich zugänglich. Bei Fig. 3 sind lediglich unterhalb des Transportbandes 3 Schutzelemente 22 angebracht, damit unterhalb dieser Schutzelemente 22 gearbeitet werden kann. In den Fig. 4 und 5 sind die Schutzelemente 22 nur als Striche dargestellt, wobei in Fig. 4 wiederum unterhalb der Stützrollen 14 - 16 und auf der Höhe des Querbalkens 25 Schutzelemente 22 positioniert sind. Bei Fig. 5 sind die Schutzelemente 22 unterhalb des unteren Transportbandes 3 und der der Stützrollen 17, 18 dargestellt. In the upper position of the support rollers 14-16 and the conveyor belt 2 of Fig. 2 and 4 stable plate elements are shown as protective elements 22 in the mounting area below both the raised upper conveyor belt 2 and above the lower conveyor belt 3, in particular with the transverse webs 25th and the vertical neck of the support structure 9 easily are detachably connected. The area between the upper and lower protective element 22 is then as far as necessary accessible to the assembly personnel. In Fig. 3 3 protection elements 22 are mounted only below the conveyor belt, so that below these protective elements 22 can be worked. 4 and 5, the protective elements 22 are shown only as dashes, wherein in Fig. 4 in turn below the support rollers 14 - 16 and at the height of the crossbar 25 protective elements 22 are positioned. In Fig. 5, the protective elements 22 below the lower conveyor belt 3 and the support rollers 17, 18 are shown.
