Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Fördern von Flächenerzeugnissen, insbesondere von Drucke­reiprodukten, gemäss dem Oberbegriff des Anspruchs 1.The present invention relates to a device for conveying flat products, in particular printed products, according to the preamble of claim 1.

Bei Vorrichtungen zum Fördern von Flächenerzeugnissen mit zwei hintereinander geschalteten Förderanordnungen besteht das Problem, dass im Bereich zwischen den beiden Förderan­ordnungen die Flächenerzeugnisse nicht abgestützt sind. Diese können beim Uebergang von der einen Förderanordnung auf die andere verletzt werden, oder laufen gar nicht auf die nachgeschaltete Förderanordnung auf, da sie zu wenig Eigensteifigkeit besitzen, um den Bereich zwischen den beiden Förderanordnungen zu überbrücken. Es ist beispiels­weise aus der FR-Al 2 334 596 bekannt, dieses Problem mit­tels endlosen, umlaufend angetriebenen Förderbändern zu lösen, welche den Endbereich der ersten Förderanordnung und den Anfangsbereich der zweiten, dieser nachgeschalte­ten Förderanordnung überlappen. Der Bereich zwischen den beiden Förderanordnungen wird also mittels eines umlaufend angetriebenen Bandförderers überbrückt, was einen erhebli­chen konstruktiven Aufwand mit sich zieht.The problem with devices for conveying flat products with two conveying arrangements connected in series is that the flat products are not supported in the area between the two conveying arrangements. These can be injured during the transition from one conveyor arrangement to the other, or do not run onto the downstream conveyor arrangement at all, since they have insufficient rigidity to bridge the area between the two conveyor arrangements. From FR-Al 2 334 596 it is known, for example, to solve this problem by means of endless, rotating driven conveyor belts which overlap the end region of the first conveyor arrangement and the beginning region of the second conveyor arrangement connected downstream of it. The area between the two conveyor arrangements is therefore bridged by means of a belt conveyor driven in rotation, which entails a considerable construction effort.

Es ist deshalb Aufgabe der vorliegenden Erfindung, eine Vorrichtung gemäss dem Oberbegriff des Anspruchs 1 zu schaffen, dessen Abstützeinrichtung mit einfachsten Mit­teln den Uebergang der Flächenerzeugnisse von der einen Förderanordnung auf die andere zuverlässig sicherstellt.It is therefore an object of the present invention to provide a device according to the preamble of claim 1, the support device of which reliably ensures the transition of the flat products from one conveyor arrangement to the other with the simplest means.

Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teiles des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Die Abstützeinrichtung weist mindestens ein schmales Ab­stützelement auf, welches stillstehend im Bereich zwischen den beiden Förderanordnungen angeordnet ist und sich in Förderrichtung der Förderanordnung erstreckt. Infolge der sehr kleinen Gleitfläche des schmalen Abstützelementes ist die Reibung zwischen den Flächenerzeugnissen und dem Ab­stützelement sehr gering, so dass trotz stillstehendem Ab­stützelement ein sicherer Uebergang der Flächenerzeugnisse von der einen Förderanordnung auf die andere sicherge­stellt ist.The support device has at least one narrow support element which is arranged stationary in the area between the two conveyor arrangements and extends in the conveying direction of the conveyor arrangement. As a result of the very small sliding surface of the narrow support element, the friction between the surface products and the support element is very low, so that despite the stationary support element, a secure transition of the surface products from one conveyor arrangement to the other is ensured.

Bei einer bevorzugten Ausbildungsform gemäss Anspruch 3 werden Spalte zwischen dem Ende bzw. Anfang der Förderan­ordnungen und der Abstützeinrichtung vermieden.In a preferred embodiment according to claim 3, gaps between the end or beginning of the conveyor arrangements and the support device are avoided.

In einer bevorzugten Ausbildungsform sind die Förderan­ordnungen Bandförderer. Falls diese mehrere, zueinander parallele und voneinander seitlich beabstandete Förderbän­der aufweisen, so ist mindestens ein Abstützelement vorge­sehen, dass an Befestigungsstellen zwischen jeweils zwei Förderbändern fixiert ist. Eine besonders gute Abstützung wird dadurch erreicht, dass über die gesamte Breite der Bandförderer mehrere Abstützelemente vorgesehen sind, wel­che jeweils zwischen zwei Förderbändern befestigt sind.In a preferred embodiment, the conveyor arrangements are belt conveyors. If these have a plurality of conveyor belts which are parallel to one another and laterally spaced apart from one another, at least one support element is provided which is fixed at fastening points between two conveyor belts in each case. A particularly good support is achieved in that several support elements are provided over the entire width of the belt conveyors, each of which is fastened between two conveyor belts.

Es können auch zwei Abstützelemente vorgesehen sein, die an Befestigungsstellen seitlich ausserhalb der Förderbän­der befestigt sind. Eine solche Ausbildungsform eignet sich auch für Bandförderer, die nur ein einziges Förder­ band aufweisen.Two support elements can also be provided, which are fastened at fastening points laterally outside the conveyor belts. Such a form of training is also suitable for belt conveyors that only have a single conveyor have band.

In einer besonders bevorzugten Ausbildungsform sind die förderwirksamen Trume der Bandförderer von Plattenelemen­ten unterstützt, wobei die Befestigungsstellen für die Abstützelemente an den Plattenelementen vorgesehen sind. Dies ermöglicht eine äusserst einfache Konstruktion.In a particularly preferred embodiment, the conveying dreams of the belt conveyors are supported by plate elements, the fastening points for the support elements being provided on the plate elements. This enables an extremely simple construction.

In vorteilhafter Weise eignet sich die erfindungsgemässe Vorrichtung zum Fördern von in einer Schuppenformation an­fallenden Druckereiprodukten, wie Zeitungen, Zeitschriften und dergleichen, bei der vorzugsweise die in Förderrich­tung gesehen vorlaufende Kante der Druckereiprodukte von jeweils vorlaufenden Druckereiprodukt überdeckt ist. Bei einer solchen Schuppenformation wird nun die untenliegende vorlaufende Kante der Druckereiprodukte sicher auf den förderwirksamen Trum der nachgeschalteten Förderanordnung geleitet. Dies ist von besonderem Vorteil, wenn es sich bei der vorlaufenden Kante um jeweils den dem Falz gegen­überliegenden offenen Seitenrand handelt, weil dieser ohne Abstützeinrichtung auffächern könnte und somit die Gefahr für eine Verletzung der Druckereiprodukte besonders gross wäre.Advantageously, the device according to the invention is suitable for conveying printed products such as newspapers, magazines and the like which occur in a scale formation, in which the edge of the printed products leading in the conveying direction is preferably covered by the leading printed product. With such a scale formation, the leading edge of the printed products lying below is now safely guided onto the conveyor-effective strand of the downstream conveyor arrangement. This is of particular advantage if the leading edge is the open side edge opposite the fold, because this could fan out without a support device and the risk of injury to the printed products would be particularly great.

Weitere bevorzugte Ausbildungsformen sind in den weiteren abhängigen Ansprüchen angegeben.Further preferred forms of training are specified in the further dependent claims.

Ein Ausführungsbeispiel der Erfindung wird nun anhand der Zeichnung näher erläutert. Es zeigen rein schematisch:

  • Fig. 1 eine Vorrichtung mit zwei hintereinander an­geordneten Bandförderern in einem Vertikal­schnitt entlang der Linie I - I der Figur 2,
  • Fig. 2 in Draufsicht einen Teil der Vorrichtung ge­mäss Figur 1, ohne die in der Figur 1 darge­stellte Schuppenformation, und
  • Fig. 3 a-e verschiedene Ausbildungsformen von Befesti­gungsanordnungen für das Abstützelement.
An embodiment of the invention will now be explained in more detail with reference to the drawing. It shows purely schematically:
  • 1 shows a device with two belt conveyors arranged one behind the other in a vertical section along the line I - I of FIG. 2,
  • Fig. 2 in plan view a part of the device according to Figure 1, without the scale formation shown in Figure 1, and
  • Fig. 3 ae different forms of mounting arrangements for the support element.

In den Figuren 1 und 2 ist der Uebergangsbereich 8 von zwei hintereinander geschalteten Bandförderern 10, 12 mit je mehreren parallelen seitlich voneinander beanstandeten, in Förderrichtung F umlaufend angetriebenen Förderbändern 14 dargestellt. Die Förderbänder 14 sind am Ende bzw. An­fang der Bandförderer 10, 12 um Walzen 16 geführt, welche auf Wellen 18 sitzen. Die Wellen 18 sind an schematisch dargestellten Lagern 20 drehbar gelagert, welche ihrer­seits an seitlichen Lagerschildern 22 der Bandförderer 10, 12 befestigt sind. Die förderwirksame Trume der Förder­bänder 14 gleiten über Abstützplatten 24, welche ebenfalls an den Lagerschildern 22 fixiert sind.FIGS. 1 and 2 show the transition region 8 of two belt conveyors 10, 12 connected in series, each with a plurality of parallel conveyor belts 14 which are laterally spaced apart and driven in the direction of conveyance F. The conveyor belts 14 are guided at the end or beginning of the belt conveyors 10, 12 around rollers 16 which sit on shafts 18. The shafts 18 are rotatably supported on schematically illustrated bearings 20, which in turn are attached to side bearing plates 22 of the belt conveyors 10, 12. The conveying effective dreams of the conveyor belts 14 slide over support plates 24, which are also fixed to the end plates 22.

An den Abstützplatten 24 sind jeweils im Bereich zwischen zwei Förderbändern 14 reibungsarme saitenförmige Abstütz­elemente 26, z. Bsp. Kunststoff- oder Stahlsaiten, befe­stigt, welche den Bereich zwischen den beiden Bandförder­ern 10, 12 auf der Höhe der förderwirksamen Trume der För­derbänder 14 überbrücken.On the support plates 24 14 low-friction string-shaped support elements 26, z. For example, plastic or steel strings fastened, which bridge the area between the two belt conveyors 10, 12 at the height of the conveyor belts 14 that are effective for conveying.

Die von den Bandförderern 10, 12 in Förderrichtung F transportierten gefalteten Druckereiprodukte 28 (siehe Figur 1) sind in einer Schuppenformation S angeordnet, in welcher das jeweils vorlaufende Druckereiprodukt 28 auf dem nachfolgenden aufliegt; die vorlaufenden Kanten 30 der Druckereiprodukte 28 sind somit untenliegend. Bei der vor­laufenden Kante 30 handelt es sich jeweils um den dem Falz 32 der Druckereiprodukte 28 gegenüberliegenden offenen Seitenrand. Im Bereich der Bandförderer 10, 12 liegt jede vorlaufende Kante 30 auf dem Förderwirksamen Trum der För­derbänder 14 auf und im Bereich zwischen den beiden Band­förderern 10, 12 werden die vorlaufenden Kanten 30 von den Abstützelementen 26 abgestützt. Die Abstützelemente 26 verhindern somit ein Auffächern des dem Falz 32 gegenüber­liegenden offenen Seitenrandes der Druckereiprodukte 28 und leiten die vorlaufenden Kanten 30 auf die förderwirk­samen Trume der Förderbänder 14 des zweiten Bandförderers 12. Die Druckereiprodukte 28 werden auch definiert vom ersten Bandförderer 10 abgelöst und können im Bereich zwi­schen den beiden Bandförderern 10, 12 nicht frei nach unten durchhängen, sich so aus der Schuppenformation S lösen und nach unten wegfallen.The folded printed products 28 transported by the belt conveyors 10, 12 in the conveying direction F (see FIG. 1) are arranged in a scale formation S, in which the respectively leading printed product 28 rests the subsequent one; the leading edges 30 of the printed products 28 are thus below. The leading edge 30 is in each case the open side edge opposite the fold 32 of the printed products 28. In the area of the belt conveyors 10, 12, each leading edge 30 rests on the effective conveyor strand 14 of the conveyor belts 14 and in the area between the two belt conveyors 10, 12, the leading edges 30 are supported by the support elements 26. The supporting elements 26 thus prevent the open side edge of the printed products 28 opposite the fold 32 from fanning out and guide the leading edges 30 onto the conveying strands of the conveyor belts 14 of the second belt conveyor 12. The printed products 28 are also detached from the first belt conveyor 10 in a defined manner and can be in the area do not sag freely between the two belt conveyors 10, 12, thus detach themselves from the scale formation S and fall downward.

In der Figur 3 sind verschiedene Befestigungsarten der Ab­stützelemente 26 dargestellt, wobei in den Figuren 3 a-d jeweils nur das eine Ende der Abstützelemente 26 gezeigt ist. Gemäss Figur 3 a ist der Endbereich des Abstützele­mentes 26 zwischen zwei von einander ungefähr um den Durchmesser des Abstützelementes 26 beabstandete Stifte 34 hindurchgeführt und wird mittels einer am Ende des Ab­stützelementes 26 vorgesehenen Verdickung 36, beispiels­weise einer Plombe, festgehalten.FIG. 3 shows different types of fastening of the support elements 26, only one end of the support elements 26 being shown in FIGS. 3 a-d. According to FIG. 3 a, the end region of the support element 26 is passed between two pins 34 spaced approximately from one another by the diameter of the support element 26 and is held in place by means of a thickening 36 provided at the end of the support element 26, for example a seal.

Bei einer Ausführungsform gemäss Figur 3 b weist die Ab­stützplatte 24 (vergl. Fig. 1 und 2) eine Bohrung 38 auf, durch welche der Endbereich des Abstützelementes 26 ge­ führt ist. Das Ausfädeln des Abstützelementes 26 aus der Bohrung 38 wird ebenfalls durch eine Verdickung 36 ver­hindert.In an embodiment according to FIG. 3 b, the support plate 24 (see FIGS. 1 and 2) has a bore 38 through which the end region of the support element 26 ge leads is. The thickening of the support element 26 out of the bore 38 is also prevented by a thickening 36.

In der Figur 3 c ist der Endbereich des Abstützelementes 26 zwischen der Abstützplatte 24 und einer mittels einer Schraube 40 an der Abstützplatte 24 befestigten Unterlags­scheibe 42 festgeklemmt.In FIG. 3 c, the end region of the support element 26 is clamped between the support plate 24 and a washer 42 fastened to the support plate 24 by means of a screw 40.

In der Figur 3 d befindet sich das Ende des Abstützelemen­tes 26 in einer Querbohrung 44 durch eine rechtwinklig zum Abstützelement 26 verlaufenden Spannwelle 46. Der Endbe­reich des Abstützelementes 26 ist um die Spannwelle 46 ge­wickelt.In FIG. 3 d, the end of the support element 26 is located in a transverse bore 44 through a tensioning shaft 46 running at right angles to the support element 26. The end region of the support element 26 is wound around the tensioning shaft 46.

Gemäss Figur 3 e bildet das Abstützelement 26 eine endlose Schlaufe, welche zwei Befestigungsbolzen 48 umgreift, wel­che im End- bzw. Anfangsbereich der beiden Bandförderer 10, 12 vorgesehen sind.According to FIG. 3 e, the support element 26 forms an endless loop, which encompasses two fastening bolts 48, which are provided in the end or start area of the two belt conveyors 10, 12.

Selbstverständlich können auch Abstützelemente 26 vorgese­hen sein, die seitlich ausserhalb der Förderbänder 14 der Bandförderer 10, 12 angeordnet sind. Diese können bei­spielsweise ebenfalls an den Abstützplatten 24 im Bereich zwischen den äussersten Förderbändern 14 und der Lager­schilder 22 befestigt sein. Eine solche Anordnung der Ab­stützelemente 26 eignet sich auch für Bandförderer 10, 12 mit nur je einem Förderband, wobei diese Förderbänder je­weils schmäler sind, als die zu transportierenden Flächen­erzeugnisse. Die faden-, draht-, schnur- oder litzenför­migen Abstützelemente 26 können an ihren beiden Enden un­terschiedlich oder gleich ausgebildet sein. So kann bei­ spielsweise am einen Ende eine Verdickung 36 vorgesehen sein, um das Abstützelement 26 an diesem Ende gemäss Figur 3 a oder b zu halten, und das andere Ende gemäss Figur 3 c festgeklemmt, oder gemäss Figur 3 d fixiert sein. Dies er­möglicht ein problemloses Spannen der Abstützelemente 26. Des weitern eignen sich diese Abstützelemente 26 insbeson­dere auch für Förderanordnungen mit Nockenförderern.Of course, support elements 26 can also be provided, which are arranged laterally outside the conveyor belts 14 of the belt conveyors 10, 12. These can also be fastened, for example, to the support plates 24 in the area between the outermost conveyor belts 14 and the end shields 22. Such an arrangement of the support elements 26 is also suitable for belt conveyors 10, 12 with only one conveyor belt each, these conveyor belts being narrower than the flat products to be transported. The thread, wire, cord or strand-shaped support elements 26 can be designed differently or identically at their two ends. So at for example, a thickening 36 may be provided at one end in order to hold the support element 26 at this end according to FIG. 3 a or b, and the other end may be clamped according to FIG. 3 c or fixed according to FIG. 3 d. This enables problem-free tensioning of the support elements 26. Furthermore, these support elements 26 are also particularly suitable for conveyor arrangements with cam conveyors.

Die Abstützelemente können auch durch vertikale, schmale Stege gebildet sein, die von der einen Förderanordnung zur anderen verlaufen. Diese können beiderends an den Förder­anordnungen befestigt sein; es ist aber auch denkbar, die Stege nur einseitig an der einen Förderanordnung zu fixie­ren. Vorteilhafterweise greifen auch diese Stege in die Förderstrecken der Förderanordnungen ein, um Spalte zwi­schen diesen und den Stegen zu vermeiden.The support elements can also be formed by vertical, narrow webs which run from one conveyor arrangement to the other. These can be attached to the conveyor arrangements at both ends; but it is also conceivable to fix the webs only on one side to the one conveyor arrangement. Advantageously, these webs also engage in the conveyor sections of the conveyor arrangements in order to avoid gaps between them and the webs.
