Description

Die Erfindung betrifft eine Bandfördervorrichtung nach dem Oberbegriff des unabhängigen Patentausspruchs 1.The invention relates to a belt conveyor device according to the preamble of independent patent claim 1.

Im Stand der Technik ist durch die EP-A- 0005766 eine Bandfördervorrichtung bekannt, die zwei parallel nebeneinander angeordnete, gleichförmig angetriebene Förderbänder aufweist, mit denen der Abstand zwischen seitlich versetzen Längsfördereinrichtungen überbrückt wird. Mit dieser Bandfördervorrichtung kann lediglich ein Produktestrom gefördert werden. Auch ist diese Vorrichtung nicht geeignet, wahlweise Produkte mit unterschiedlichen Formaten und insbesondere der gebräuchlichen Breiten von 150mm bis 500mm zu fördern. Diese Vorrichte ist vielmehr auf wenige Formate beschränkt. Bei dieser bekannten Vorrichtung besteht zudem die Gefahr, dass bei gewissen Formaten die Produkte bei den Uebergabestellen eingeklemmt werden und die Anlage blockiert sowie beschädigt wird.In the prior art, EP-A-0005766 discloses a belt conveyor device which has two uniformly driven conveyor belts which are arranged in parallel next to one another and with which the distance between laterally offset longitudinal conveyor devices is bridged. Only a product flow can be conveyed with this belt conveyor device. This device is also not suitable for conveying products with different formats and in particular the usual widths of 150 mm to 500 mm. Rather, this device is limited to a few formats. With this known device, there is also the risk that, in certain formats, the products may become jammed at the transfer points and the system may be blocked and damaged.

Der Antrieb der Bandfördervorrichtung nach der DE-A-27 21 138 erfolgt über Antriebsrollen, die mit Bandrollen verbunden sind. Diese Rollen sind über Zwischenwellen sowie Antriebsbänderr von den anschliessenden Bandförderelementen angetrieben. Auch hier können beide jeweils miteinander verbundene Förderbänder nur parallel zueinander verschwenkt werden. Die beiden Banspaare sind hier zwar unabhänging voneinander verschwenkbar, diese können jedoch zum Fördern von sehr breiten Druckprodukten nicht ohne aufwendigen Umbau zusammengelegt werden.The belt conveyor device according to DE-A-27 21 138 is driven by drive rollers which are connected to belt rollers. These rollers are driven by the subsequent belt conveyor elements via intermediate shafts and drive belts. Here, too, both conveyor belts connected to each other can only be pivoted parallel to one another. Although the two pairs of bans can be swiveled independently of one another, they cannot be folded together without the need for extensive conversion to convey very wide print products.

Der erfindung liegt somit die Aufgabe zugrunde, eine Bandfördervorrichtung der eingangs genannten Art zu schaffen, mit der wahlweise ein oder zwei Produkteströme weitergefördert werden können, wobei die Produkte im wesentlichen alle üblichen Formate aufweisen können und die Gefahr einer Blokkierung der Anlage geringer ist.The invention is therefore based on the object of creating a belt conveyor device of the type mentioned at the outset, with which one or two product streams can optionally be conveyed further, the products being essentially all of them can have the usual formats and the risk of blocking the system is lower.

Die Aufgabe wird durch die Erfindung gemäss Anspruch 1 gelöst. Bei Produkten mit sehr grossem Format kann eine Bandgruppe mit beispielsweise vier Förderbändern zusammengestellt werden. Da bezüglich der Formatbreite mehr Förderbänder als bisher vorhanden sind, ist die Gefahr wesentlich geringer, dass bei einer Uebergabestelle ein Produkt eingeklemmt wird und die Ablage blockiert wird. Bei Produkten mit kleineren Formatbreiten werden entsprechend weniger Bänder eingesetzt. Sind zwei beispielsweise von einem Falzapparat abgelegte Schuppenströme zu fördern, so werden die beiden Bandgruppen V-förmig angeordnet, wobei jede Bandgruppe die Anzahl Bänder aufweist, die für die Breite des jeweiligen Schuppenstroms geeignet ist. Wesentlich ist, dass bei beiden Schuppenströmen die Richtungen der Vorderkanten der Produkte nicht ändern und somit- die seitlichen Versetzungen der nachgeordneten Schuppenströme durch ein Verschwenken der Förderbänder genau eingestellt und verstellt werden können.The object is achieved by the invention according to claim 1. For products with a very large format, a belt group with, for example, four conveyor belts can be put together. Since there are more conveyor belts than previously with regard to the format width, the risk is significantly lower that a product is jammed at a transfer point and the storage is blocked. Correspondingly fewer tapes are used for products with smaller format widths. If two shingled streams deposited, for example, by a folder are to be conveyed, the two belt groups are arranged in a V-shape, each belt group having the number of belts which is suitable for the width of the respective shingled stream. It is essential that the directions of the front edges of the products do not change in both shingled streams and thus the lateral displacements of the downstream shingled streams can be precisely adjusted and adjusted by pivoting the conveyor belts.

Durch die Erfindung ist es möglich, die einzelnen Förderbänder nahe nebeneinander anzuordnen und auch bei einer grösseren Anzahl Förderbänder diese gemeinsam anzutreiben. Der nun mögliche kurze Abstand zwischen den Förderbändern hat den wesentlichen Vorteil, dass auch dann zwei Schuppenströme störungsfrei gefördert werden können, wenn der Abstand zwischen diesen sehr klein ist. Ein gemeinsamer Antrieb arbeitet mit Gelenkwellen, mit denen die Förderbänder gekuppelt sind. Damit die Gelenkwellen die notwendige Länge aufweisen, sind diese zwischen zwei im Bereich der voneinander abgewandten Flanken der Förderorgane jeweils vorgesehenen Vorlegers angebracht. Eine derartige Anordnung von Vorlegern wäre aber bereits bei drei Förderbändern prinzipiell nicht möglich. Durch die Weiterbildung nach Anspruch 2 kann hingegen in konstruktiv einfacher Weise eine Bandfördervorrichtung mit acht oder mehr vergleichsweise schmalen und nahe beinander liegenden Förderbändern realisiert werden, die bis zu 25 Grad oder mehr verschwenkbar sind.The invention makes it possible to arrange the individual conveyor belts close to one another and even together with a larger number of conveyor belts to drive. The now possible short distance between the conveyor belts has the essential advantage that two scale streams can also be conveyed without interference if the distance between them is very small. A common drive works with cardan shafts with which the conveyor belts are coupled. So that the cardan shafts have the necessary length, they are attached between two feeders provided in the region of the flanks of the conveying members facing away from each other. In principle, such an arrangement of feeders would not be possible with three conveyor belts. The development according to claim 2, however, can be implemented in a structurally simple manner, a belt conveyor device with eight or more comparatively narrow and closely spaced conveyor belts that can be pivoted up to 25 degrees or more.

Durch die Weiterbildung nach Anspruch 2 ist es möglich, jede Bandgruppe unabhängig von der anderen zu verschwenken und damit in Anpassung an den Falzapparat und die nachgeordneten Organe eine optimale Weiterförderung der Produktestrome zu gewährleisten.Through the development according to claim 2, it is possible to pivot each band group independently of the other and thus to ensure optimal further conveyance of the product streams in adaptation to the folder and the downstream organs.

Nach den Weiterbildungen gemäss den Ansprüchen 3 bis 5 wird ein aufgrund seiner einfachen und robusten Ausführung in der Herstellung kostengünstiger Antrieb geschaffen, der zudem betrieblich sehr zuverlässig ist.According to the further developments according to claims 3 to 5, an inexpensive drive is created due to its simple and robust design, which is also very reliable in operation.

Durch die Weiterbildung nach Anspruch 6 ist es in konstruktiv einfacher Weise möglich, jede Schwenklage wenigstens von -25 Grad bis +25 Grad präzise und stufenlos einzustellen. Zudem kann mit wenigen Handgriffen ein Förderband der einen Bandgruppe der anderen Bandgruppe zugeordnet werden.Through the development according to claim 6, it is possible in a structurally simple manner to set each swivel position precisely and continuously at least from -25 degrees to +25 degrees. In addition, a conveyor belt from one belt group can be assigned to the other belt group in a few simple steps.

Durch die Weiterbildung nach Anspruch 7 wird im Produktestrom am Eingang und am Ausgang jeder Bandgruppe ein Art "Wasserfall" gebildet, der die Produkte voneinander trennt und ihre seitliche Verschiebbarkeit verbessert. Es hat sich gezeigt, dass mit dieser Massnahme auch die Gefahr einer Blockierung nach einem Rückstau weiter vermindert wird.Through the development according to claim 7, a kind of "waterfall" is formed in the product flow at the entrance and exit of each belt group, which separates the products from one another and improves their lateral displaceability. It has been shown that this measure also further reduces the risk of blocking after a backflow.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend an Hand der Zeichnung näher erläutert. Es zeigen:

  • Fig. 1 eine Draufsicht auf eine erfindungsgemässe Bandfördereinrichtung und schematisch eine erste und zwei Längsfördereinrichtungen,
  • Fig. 2 eine Seitenansicht der Bandfördervorrichtung in Richtung des Pfeiles II in Fig. 3 gesehen, jedoch ohne Seitenabdeckung,
  • Fig. 3 eine Draufsicht auf einen Teil der erfindungsgemässen Bandfördervorrichtung,
  • Fig. 4 einen Schnitt entlang der Linie IV - IV in Fig. 3 und
  • Fig. 5 eine Schnitt entlang der Linie V - V in Fig. 3.
An embodiment of the invention is explained below with reference to the drawing. Show it:
  • 1 is a plan view of a belt conveyor device according to the invention and schematically a first and two longitudinal conveyor devices,
  • 2 is a side view of the belt conveyor in the direction of arrow II in FIG. 3, but without a side cover,
  • 3 shows a plan view of a part of the belt conveyor device according to the invention,
  • Fig. 4 is a section along the line IV - IV in Fig. 3 and
  • 5 shows a section along the line V - V in FIG. 3.

Die in Fig. 1 gezeigte Bandfördervorrichtung weist in V-förmiger Anordnung eine erste Gruppe 3 von vier Förderbändern 5 und eine zweite Gruppe 4 von ebenfalls vier Förderbändern 5 auf, die zwei Schuppenströme von einer ersten Längsfördereinrichtung 2 zu zwei zweiten Längsfördervorrichtungen 8 und 9 fördern. Die Schuppenströme werden durch flächige Produkte 1, insbesondere Druckprodukte, beispielsweise Zeitungen, gebildet, die von einem hier nicht gezeigten Falzapparat abgegeben werden. Die Vorderkanten der Produkte 1 bleiben wie dargestellt parallel und die Produkte 1 erfahren auf den Förderorganen 3 und 4 lediglich seitliche Versetzungen um einen Betrag A, die bei der Uebergabe an die zweiten Fördereinrichtungen 8 und 9 wieder aufgehoben werden. Werden grossformatige und sehr breite Produkte 1 gefördert, so liegen diese wie gezeigt auf allen vier oder gegebenenfalls auch mehr als vier Förderbändern auf, während bei kleineren Produkten diese auf weniger, aber mindestens auf drei Förderbändern 5 aufliegen. Der Abstand B (Fig.1) zwischen der Produkten 1 kann auch sehr klein sein.1 has a first group 3 of four conveyor belts 5 and a second group 4 of likewise four conveyor belts 5, which convey two scale flows from a first longitudinal conveyor device 2 to two second longitudinal conveyor devices 8 and 9 in a V-shaped arrangement. The shingled streams are formed by flat products 1, in particular printed products, for example newspapers, which are released by a folder (not shown here). The front edges of the products 1 remain parallel, as shown, and the products 1 are only displaced laterally by an amount A on the conveying members 3 and 4, and are displaced again when they are transferred to the second conveying devices 8 and 9. If large-format and very wide products 1 are conveyed, they are shown as shown on all four or possibly more than four conveyor belts, while for smaller products these rest on fewer, but at least three, conveyor belts 5. The distance B (FIG. 1) between the products 1 can also be very small.

Die erste Gruppe und die zweite Gruppe der Förderorgane können mittels Stellvorrichtungen unabhängig voneinander in der Förderebene verschränkt werden. Hierbei wird jedes Förderband 5 um eine eigene Welle verschränkt, die in Förderrichtung gesehen am hinteren Ende angeordnet ist. Die Stellvorrichtungen können an Handrädern 12 bzw. 12′ oder auch motorisch betätigt werden. Die Winkel der Förderorgane 3 und 4 zur Förderrichtung der Fördereinrichtung sind einem Bereich von wenigstens - 25 bis + 25 Grad stufenlos verstellbar.The first group and the second group of the conveying members can be interlocked independently of one another in the conveying plane by means of adjusting devices. Here, each conveyor belt 5 is entangled by its own shaft, which is arranged at the rear end when viewed in the conveying direction. The actuators can be operated on handwheels 12 or 12 'or by motor. The angles of the conveying members 3 and 4 to the conveying direction of the conveying device are infinitely adjustable over a range of at least - 25 to + 25 degrees.

Wie die Fig. 2 zeigt, liegt die Förderbene der Förderorgane 3 und 4 etwas tiefer als diejenige der Längsfördereinrichtung 2 und diejenige der Längsfördereinrichtung 9 is nochmals etwas tiefer angeordnet. An den Uebergabestellen nahe der Umlenkrollen 15 und 17 wird dadurch ein "Wasserfall" gebildet, der die oft aneinander haftenden Produkte 1 voneinander trennt und dadurch eine störungsfreie seitliche Verschiebung der Produkte 1 ermöglicht.As shown in FIG. 2, the conveying plane of the conveying members 3 and 4 is somewhat lower than that of the longitudinal conveying device 2 and that of the longitudinal conveying device 9 is again arranged somewhat lower. At the transfer points near the deflection rollers 15 and 17, a "waterfall" is thereby formed, which separates the products 1, which are often stuck to one another, and thereby enables the products 1 to be displaced without interference.

Die Bandgruppen 3 und 4 weisen jeweils mehrere endlose Förderbänder 5 auf, die gemeinsam entweder direkt vom Falzapparat oder durch einen gesammelten Getriebemotor angetrieben werden. Als Antriebsorgan ist eine endlose, horizontal verlaufende Rollenkette 11 vorgesehen, die durch einen Antrieb 14 angetrieben und mittels eines Kettenspanners 5 gespannt sowie an einer Rolle 37 umgelenkt wird. Zwischen dem Antrieb 14 und der Umlenkrolle 37 ist die Rollenkette 11 mit Kettenrädern 36 und zwischen diesen angeordneten Umlenkrollen 33 im Eingriff.The belt groups 3 and 4 each have a plurality of endless conveyor belts 5 which are driven either directly by the folder or by a collected gear motor. An endless, horizontally running roller chain 11 is provided as the drive element, which is driven by a drive 14 and tensioned by means of a chain tensioner 5 and is deflected on a roller 37. Between the drive 14 and the deflection roller 37, the roller chain 11 is in engagement with chain wheels 36 and deflection rollers 33 arranged between them.

Wie aus Fig. 4 hervorgeht, ist jedes Kettenrad 36 fest mit einer vertikal zur Förderebene ausgerichteten Welle 32 verbunden, die einerseits die Bewegung der Rollenkette 11 über ein Getriebe 34 auf das Förderband 5 überträgt und an der anderseits das Förderband 5 schwenkbar gelagert und abgestützt ist. Die Welle 32 ist mit zwei Lagern 18 und 41 an zwei Lagerplatten 38 und 48 gelagert, die sich über die ganze Rollenkette 11 erstrecken und diese insbesondere gegen ein Eindringen von Papierstaub schützen. Weitere Lager 40 und 41 der Welle 32 sind in ein Gehäuse 25 eingesetzt und erlauben eine Schwenkbewegung des Gehäuses 25 um die Achse der Welle 32.As can be seen from FIG. 4, each sprocket 36 is firmly connected to a shaft 32 oriented vertically to the conveying plane, which on the one hand transmits the movement of the roller chain 11 via a gear 34 to the conveyor belt 5 and on the other hand the conveyor belt 5 is pivotably supported and supported . The shaft 32 is supported by two bearings 18 and 41 on two bearing plates 38 and 48 which extend over the entire roller chain 11 and protect them in particular against the ingress of paper dust. Further bearings 40 and 41 of the shaft 32 are inserted into a housing 25 and allow the housing 25 to pivot about the axis of the shaft 32.

In das Gehäuse 25 sind zwei weitere Lager 24 eingesetzt, in denen die horizontale Welle 23 einer schmalen Bandrolle 22 drehbar gelagert ist. Der Antrieb der Bandrolle 22 erfolgt über ein fest mit der Welle 32 verbundenes Kegelrad 20, das mit einem fest mit der Förderrolle 22 verbundenem Tellerrad 21 kämmt. Wie die Fig. 4 weiter zeigt, liegt die Drehachse der Welle 32 ausserhalb der Mitte des Förderbandes 5, das wesentlich schmaler ist als des Gehäuses 25. Das Band 5 läuft um eine am anderen Ende des Gehäuse 25 angeordnete Umlenkrolle 16 (Fig. 2).In the housing 25 two further bearings 24 are inserted, in which the horizontal shaft 23 of a narrow belt roll 22 is rotatably mounted. The belt roller 22 is driven via a bevel gear 20 which is fixedly connected to the shaft 32 and which meshes with a ring gear 21 which is fixedly connected to the conveyor roller 22. As FIG. 4 further shows, the axis of rotation of the shaft 32 lies outside the center of the conveyor belt 5, which is much narrower than the housing 25. The belt 5 runs around a deflection roller arranged at the other end of the housing 25 16 (Fig. 2).

Die Stellvorrichtung zum Verschwenken der Förderorgane 3 und 4 weisen jeweils eine Spindel 13 bzw. 13′ auf, die parallell zueinander und senkrecht zur Förderrichtung angeordnet sind und die jeweils an ihren beiden Enden im Rahmen 38 gelagert und gehalten sind.The actuating device for pivoting the conveying members 3 and 4 each have a spindle 13 or 13 ', which are arranged parallel to one another and perpendicular to the conveying direction and which are each supported and held in the frame 38 at their two ends.

Jede Spindel 13 bzw. 13′ kann an einem Handrad 12 bzw. 12′ betätigt werden. Die Spindeln 13′ bzw. 13 greifen bei jedem Förderorgan 3 bzw. 4 das sie verstellen soll, in eine Gewindebohrung 26 eines Körpers 31 ein, der mittels einer Drehverbindung 27 auf der Unterseite eines Körpers 30 angebracht ist. Der Körper 30 besteht vorzugsweise aus Kunststoff und ist gleitverschiebbar an zwei Platten 43 und 44 und in einem Schlitz 46 auf zwei Hülsen 45 geführt, die mittels Schrauben 28 bzw. 29 am Gehäuse 25 befestigt sind. Da der Körper 30 somit um die vertikale Achse des Drehlagers 27 drehen und auch in Längsrichtung des Gehäuses 25 verschiebbar ist, lässt sich zwangslos jede Schräglage des entsprechenden Förderorgans 3 bzw. 4 einstellen.Each spindle 13 or 13 'can be operated on a handwheel 12 or 12'. The spindles 13 'and 13 engage in each conveyor 3 or 4 that they should adjust, in a threaded bore 26 of a body 31 which is attached by means of a rotary connection 27 on the underside of a body 30. The body 30 is preferably made of plastic and is slidably guided on two plates 43 and 44 and in a slot 46 on two sleeves 45 which are fastened to the housing 25 by means of screws 28 and 29, respectively. Since the body 30 thus rotates about the vertical axis of the rotary bearing 27 and can also be displaced in the longitudinal direction of the housing 25, any inclined position of the corresponding conveying element 3 or 4 can be set without any problems.

Aus den obigen Angaben ergibt sich somit eine Bandfördervorrichtung, die trotz ihrer hohen Variabilität und Anpassbarkeit aus vergleichsweise wenigen und einfachen Einzelteilen besteht und die auch sonst den fördertechnischen Anforderungen in hohem Masse genügt und die zudem im Betrieb äusserst zuverlässig ist.The above information thus results in a belt conveyor device which, despite its high variability and adaptability, consists of comparatively few and simple individual parts and which also otherwise satisfies the conveyor requirements to a high degree and which is also extremely reliable in operation.
