TRANSPORTBAND MIT PROFILIERTER OBERFLACHE SOWIE VERFAHREN ZUM VERBINDEN DER BEIDEN BANDENDEN EINES SOLCHEN TRANSPORTBANDESCONVEYOR BELT WITH A PROFILED SURFACE AND METHOD FOR CONNECTING THE BOTH TAPES OF SUCH A CONVEYOR BELT

Die vorliegende Erfindung bezieht sich auf ein Transportband mit profilierter Oberfläche zur Beförderung von rollfähigem Transportgut sowie auf ein Verfahren zum Verbinden der beiden Bandenden eines solchen Transportbandes .The present invention relates to a conveyor belt with a profiled surface for conveying goods that can be rolled and to a method for connecting the two belt ends of such a conveyor belt.

Transportbänder mit profilierter Oberfläche werden beispielsweise zur Beförderung von Gepäck an Flughäfen, von landwirtschaftlichen Erzeugnissen, wie z.B. Kartoffeln oder Rüben, oder von anderem grobem Schüttgut eingesetzt. Solche Transportbänder müssen derart aufgebaut und ihre Oberfläche derart gestaltet sein, dass sie folgende Eigenschaften aufweisen :Conveyor belts with a profiled surface are used, for example, for the transport of luggage at airports, of agricultural products, such as Potatoes or beets, or from other coarse bulk goods. Such conveyor belts must be constructed and their surface designed in such a way that they have the following properties:

• Gewährleistung der Mitnahme von rollfähigem Transportgut, wie Koffern mit Rollen, Kartoffeln, Rüben und anderem grobem Schüttgut, wobei grob in diesem Zusammenhang bedeutet, dass der kleinste Durchmesser mindestens 5 mm beträgt ;• Ensuring the transport of goods that can be rolled, such as suitcases with rolls, potatoes, beets and other coarse bulk goods, whereby coarse in this context means that the smallest diameter is at least 5 mm;

• Verhinderung von grossen Relativbewegungen zwischen Transportband und Transportgut beim Beschleunigen und Abbremsen; und• Prevention of large relative movements between the conveyor belt and the goods to be transported when accelerating and braking; and

• Möglichkeit des Einsatzes bei ansteigenden und abfallenden Transportstrecken, ohne dass das Transportgut auf dem Transportband gross umherrollt.• Possibility of use on rising and falling transport routes without the goods being rolled around on the conveyor belt.

Herkömmliche Transportbänder mit diesen Eigenschaften zeichnen sich im allgemeinen durch eine Oberfläche mit eingeprägtem Gittermuster aus. Die Stege des Gittermusters sind zwischen 2 und 5 mm hoch, etwa 3 bis 10 mm breit und formen in der Regel Quadrate oder Rhomben mit einer Kanten- länge zwischen 20 und 100 mm.Conventional conveyor belts with these properties are generally characterized by a surface with an embossed grid pattern. The bars of the grid pattern are between 2 and 5 mm high, about 3 to 10 mm wide and generally form squares or rhombuses with an edge length between 20 and 100 mm.

In Fig. 1 ist ein Beispiel eines derartigen Transportbandes 1' mit einer Transportbandoberfläche 10' und Stegen 11' dargestellt. Die Stege 11' verjüngen sich vom Fuss zur Kro- ne hin.1 shows an example of such a conveyor belt 1 'with a conveyor belt surface 10' and webs 11 '. The webs 11 'taper from the foot to the crown.

Zur Herstellung solcher Transportbänder werden in der Regel als Substrat Gewebe eingesetzt, auf welche Weich-PVC, thermoplastisches Polyurethan oder andere thermoplastische Ela- stomere in Streich- oder Schmelzbeschichtungsverfahren aufgetragen werden. Mehrere solcher beschichteter Gewebe können in einem Kaschierprozess zu mehrlagigen Körpern verbunden werden. Es sind Transportbänder mit einer, zwei oder mehr Gewebelagen denkbar. Um die oben beschriebene Oberflä- chenprägung realisieren zu können, muss gewährleistet sein, dass die zu profilierende Thermoplastschicht genügend dick ist. Die Prägung der Transportbandoberfläche erfolgt direkt nach dem Beschichten oder Kaschieren oder in einem separaten Vorgang in einer dafür vorgesehenen Prägestation.For the production of such conveyor belts, woven fabrics are generally used as the substrate, to which soft PVC, thermoplastic polyurethane or other thermoplastic elastomers are applied in a coating or melt-coating process. Several such coated fabrics can be connected to multilayered bodies in a lamination process. Conveyor belts with one, two or more fabric layers are conceivable. In order to be able to implement the surface embossing described above, it must be ensured that the thermoplastic layer to be profiled is sufficiently thick. The surface of the conveyor belt is embossed directly after coating or lamination or in a separate process in a dedicated embossing station.

In Fig. 2 ist die Prägung einer Transportbandoberfläche in einem Prägekalander 8 mit senkrechter Walzenanordnung dargestellt. Ein Transportband 1' wird über einen Breithalter 81 und eine Umlenkrolle 82 in den Walzenspalt zwischen einer gekühlten Prägewalze 83 und einer gummierten Gegendruckwalze 84 geführt und umschlingt danach die Prägewalze 83. Unmittelbar vor dem Walzenspalt wird die zu prägende Thermoplastschicht mit Infrarotstrahlern 89 auf Umformtemperatur oder höher erwärmt. Anschliessend wird die gewünschte Profilierung mittels der gravierten Prägewalze 83 eingedrückt, wobei der dazu notwendige Druck durch die gummierte Gegendruckwalze 84 gewährleistet wird. Die Gegendruckwalze 84 kann mittels einer teilweise in ein mit Kühlflüssigkeit gefülltes Kühlbecken 86 eintauchenden Kühlwalze 85 gekühlt werden. Durch .Abkühlen der Thermoplastschicht wird die geprägte Oberflächenprofilierung fixiert . Das2 shows the embossing of a conveyor belt surface in an embossing calender 8 with a vertical roller arrangement. A conveyor belt 1 'is guided over a spreader 81 and a deflection roller 82 into the nip between a cooled embossing roller 83 and a rubberized counter-pressure roller 84 and then loops around the embossing roller 83. Immediately in front of the nip, the thermoplastic layer to be embossed is heated to the forming temperature or higher with infrared radiators 89. The desired profiling is then pressed in by means of the engraved embossing roller 83, the pressure required for this being ensured by the rubberized counter-pressure roller 84. The counter-pressure roller 84 can be cooled by means of a cooling roller 85 which is partially immersed in a cooling basin 86 filled with cooling liquid. The embossed surface profile is fixed by cooling the thermoplastic layer. The

Transportband 1' gelangt dann über Umlenkrollen 90 zu Kühl- zylindern 87, 88 und wird zur weiteren Abkühlung um diese herum und schliesslich über eine Umlenkrolle 91 weggeführt.Conveyor belt 1 'then arrives at cooling cylinders 87, 88 via deflecting rollers 90 and is guided around them for further cooling and is finally led away via a deflecting roller 91.

Bei der beschriebenen Gittermuster-Prägungungsgeometrie bilden die Stege Kreuzungspunkte, die nachteilhafte Auswirkungen auf das Transportband haben. Die Kreuzungspunkte führen zu einer Versteifung des Transportbandes, was den Biegewiderstand erhöht und sich auf den minimal zulässigen Rollendurchmesser ungünstig auswirkt. Ausserdem können bei der Herstellung der Prägung an den Kreuzungspunkten Hohlräume entstehen, die Ausgangspunkte für Risse und Bruchstellen in den Stegen bilden und eine schlechte optische Qualität ergeben.In the lattice pattern embossing geometry described, the webs form crossing points which have a disadvantageous effect on the conveyor belt. The crossing points stiffen the conveyor belt, which increases the bending resistance and has an unfavorable effect on the minimum permissible roller diameter. In addition, cavities can arise during the production of the embossing at the crossing points, which form the starting points for cracks and breaking points in the webs and result in poor optical quality.

Angesichts der Nachteile der bisher bekannten, oben beschriebenen profilierten Transportbänder liegt der Erfindung die folgende Aufgabe zugrunde. Es ist ein Transportband mit profilierter Oberfläche zur Beförderung von roll- fähigem Transportgut zu schaffen, dessen Stege eine deutlich geringere Bandversteifung bewirken und mit weniger - 4 -In view of the disadvantages of the previously known profiled conveyor belts described above, the invention is based on the following object. A conveyor belt with a profiled surface is to be created for the transport of goods that can be rolled, the webs of which result in significantly less stiffening of the belt and with less - 4 -

Fehlstellen, insbesondere Hohlräumen, herstellbar sind. Das Transportband soll ausserdem gute Mitnahmeigenschaften und die Eigenschaft aufweisen, dass bei Umlenkrollen, welche auf die Bandoberfläche wirken, kein ratterndes Geräusch entsteht.Defects, especially cavities, can be produced. The conveyor belt should also have good driving properties and the property that there is no rattling noise with deflection rollers which act on the belt surface.

Diese Aufgabe wird durch das erfindungsgemässe Transportband gelöst, wie es im unabhängigen Patentanspruch 1 definiert ist . Bevorzugte Ausführungsvarianten ergeben sich aus den abhängigen Patentansprüchen. In Patentanspruch 9 ist ein erfindungsgemässes Verfahren zum Verbinden der beiden Bandenden und in Patentanspruch 10 eine erfindungsgemässe Verwendung eines solchen Transportbandes definiert.This object is achieved by the conveyor belt according to the invention as defined in independent claim 1. Preferred design variants result from the dependent patent claims. A method according to the invention for connecting the two belt ends is defined in patent claim 9 and a use of such a conveyor belt according to the invention is defined in patent claim 10.

Das Wesen der Erfindung besteht darin, dass bei einemThe essence of the invention is that in one

Transportband mit profilierter Oberfläche zur Beförderung von rollfähigem Transportgut die Transportbandoberfläche mehrere kontinuierliche, in Längsrichtung verlaufende, nicht geradlinige Stege aufweist, die sich nicht berühren.Conveyor belt with a profiled surface for the transport of goods that can be rolled, the conveyor belt surface has several continuous, longitudinal, non-straight webs that do not touch.

Durch die erfindungsgemässe .Anordnung der Stege treten keine Kreuzungspunkte auf, wodurch das Transportband flexibler und weniger anfällig auf Störstellen und Fehler ist, die von diesen ausgehen, als die herkömmlichen profilierten Transportbänder. Die kontinuierlich verlaufenden Stege verhindern das Einbauen von Fehlstellen, z.B. Lufteinschlüs- sen, während des Prägevorgangs. Das Fehlen toter Ecken verhindert ausserdem die Schmutzansammlung und erhöht die Rei- nigungsfreundlichkeit .Due to the arrangement of the webs according to the invention, there are no crossing points, as a result of which the conveyor belt is more flexible and less susceptible to imperfections and errors emanating from them than the conventional profiled conveyor belts. The continuous webs prevent the installation of imperfections, e.g. Air pockets during the embossing process. The absence of dead corners also prevents dirt from accumulating and increases ease of cleaning.

Dadurch, dass sich die in Längsrichtung verlaufenden Stege nicht berühren, kann auf das Transportband gelangende Flüssigkeit zwischen den Stegen abfliessen, womit Flüssigkeits- ansammlungen auf der Transportbandoberfläche vermieden werden .The fact that the webs running in the longitudinal direction Do not touch, liquid on the conveyor belt can flow between the webs, thus avoiding liquid accumulation on the conveyor belt surface.

Da die Stege kontinuierlich und in Längsrichtung nicht unterbrochen sind, liegen sie permanent an etwaigen Rollen an und erzeugen kein ratterndes Geräusch.Since the webs are continuous and not interrupted in the longitudinal direction, they are permanently in contact with any rollers and do not generate a rattling noise.

Bei einer bevorzugten Ausführungsvariante sind die beiden Bandenden eines erfindungsgemässen Transportbandes so miteinander verbunden, dass die Stege kontinuierlich über die Verbindungszone verlaufen. Dadurch wird auch in der Verbindungszone die Erzeugung eines ratternden Geräusches vermie- den.In a preferred embodiment variant, the two belt ends of a conveyor belt according to the invention are connected to one another in such a way that the webs run continuously over the connection zone. This also prevents the generation of a rattling noise in the connection zone.

Im folgenden werden das erfindungsgemässe Transportband und das erfindungsgemässe Verfahren zum Verbinden der beiden Bandenden eines Transportbandes unter Bezugnahme auf die beigefügten Zeichnungen anhand von drei Ausführungsbeispie- len detaillierter beschrieben.

In die obere Thermoplastschicht 2 ist die Transportbandoberfläche 10 mit Stegen 11 eingeprägt.Conveyor belts known thermoplastics, in particular PVC or polyurethane, can be used. The conveyor belt surface 10 is embossed with webs 11 in the upper thermoplastic layer 2.

Die Stege 11 verlaufen wellenförmig und bezüglich der Längsrichtung des Transportbandes 1 spiegelbildlich. Sie weisen eine Höhe h zwischen 2 und 10 mm, eine untere Stegbreite b2 zwischen 2 und 12 mm, eine obere Stegbreite bλ zwischen 2 und 12 mm und im vorliegenden Fall einen trapezförmigen Querschnitt auf . Der minimale .Abstand amin zweier benachbarter Stege 11 beträgt zwischen 3 und 50 mm und der maximale Abstand amax zwischen 15 und 200 mm. Der Abstand c zweier benachbarter Stellen mit minimalem Stegabstand amin liegt zwischen 15 und 200 mm.The webs 11 run in an undulating manner and are mirror images of the longitudinal direction of the conveyor belt 1. They have a height h between 2 and 10 mm, a lower web width b 2 between 2 and 12 mm, an upper web width b λ between 2 and 12 mm and in the present case a trapezoidal cross section.

Otherwise, what has been said in connection with FIGS. 3 and 4 applies.

Figuren 7 und 8 Die beiden Bandenden 105 und 106 des Transportbandes 101 sind so fingerartig miteinander verbunden, dass die Trans- - 8 - portbandoberflache 110 inklusive der Stege 111 kontinuierlich über die Verbindungszone 107 verläuft.FIGS. 7 and 8 The two belt ends 105 and 106 of the conveyor belt 101 are connected to one another in a finger-like manner such that the conveyor belt - 8 - port belt surface 110 including the webs 111 runs continuously over the connection zone 107.

Das Endlosmachen des Transportbandes 101 kann mit einem er- findungsgemässen Verfahren zum Verbinden der beiden Bandenden 105 und 106 erfolgen, das folgende Schritte umfasst : a) Ausstanzen von komplementären Zacken an den beiden Bandenden 105, 106; b) Ineinanderverzahnen der beiden Bandenden 105, 106; c) Legen einer gravierten Metallplatte auf die Verbindungszone 107 der beiden Bandenden 105, 106, wobei die Gravur der Oberflächengeometrie des Transportbandes 101 in der Verbindungszone 107 entspricht; und d) Pressen der Metallplatte gegen das Transportband 101 unter WärmeZuführung, was gewöhnlich in einer Endver- bindungspresse geschieht .The conveyor belt 101 can be made endless using a method according to the invention for connecting the two belt ends 105 and 106, which comprises the following steps: a) punching out complementary tines on the two belt ends 105, 106; b) interlocking of the two band ends 105, 106; c) placing an engraved metal plate on the connecting zone 107 of the two belt ends 105, 106, the engraving corresponding to the surface geometry of the conveyor belt 101 in the connecting zone 107; and d) pressing the metal plate against the conveyor belt 101 with the application of heat, which is usually done in an end connection press.

Das Ausstanzen der Zacken muss an beiden Bandenden 105, 106 so aufeinander abgestimmt sein, dass beim Ineinanderverzah- nen der beiden Bandenden 105, 106 in der Verbindungszone 107 ein durchgehendes Profil entsteht. Dies bedingt ein komplementäres Anordnen der Zacken bezüglich der Oberflächengeometrie an den beiden Bandenden 105, 106. Um den Satz notwendiger gravierter Metallplatten zu beschränken, wird die Anzahl der erlaubten Zackenanordnungen bezüglich der Oberflächengeometrie vorteilhafterweise auf 3 bis 5 beschränkt .The punching out of the teeth must be coordinated with one another at both band ends 105, 106 in such a way that when the two band ends 105, 106 are interlocked, a continuous profile is created in the connecting zone 107. This requires a complementary arrangement of the prongs with respect to the surface geometry at the two band ends 105, 106. In order to limit the set of necessary engraved metal plates, the number of permitted prong arrangements with respect to the surface geometry is advantageously limited to 3 to 5.

Durch das Pressen der Metallplatte gegen das Transportband 101 unter WärmeZuführung werden die ineinander verzahnten Bandenden 105, 106 verschweisst . Dabei wird die Gravur der Metallplatte auf das Transportband 101 übertragen und der Unterbruch der Profilierung in der Verbindungszone 107 verschwindet .By pressing the metal plate against the conveyor belt 101 while supplying heat, the intermeshed belt ends 105, 106 are welded. The engraving of the Transfer the metal plate to the conveyor belt 101 and the interruption of the profiling in the connecting zone 107 disappears.

Zu den vorbeschriebenen Transportbändern sind weitere konstruktive Variationen realisierbar. Hier ausdrücklich erwähnt sei noch, dass auch unregelmassige Stegverläufe denkbar sind. Further design variations can be implemented for the conveyor belts described above. It is expressly mentioned here that irregular web runs are also conceivable.
