Abstract

Underneath a support table for a cover element or sheet there are positioned a number of receiving or storage bins for additional or supplementary sheets. Between the receiving or storage bins and the support table there is placed a conveyor belt. One run of the conveyor belt is pressed against the underside of the support table. A thrust element for advancing the cover element is coupled with the conveyor belt. A piston-cylinder unit displaces the conveyor belt and the thrust element in a direction of movement towards a deposit device. During this displacement the one run of the conveyor belt rolls at the support table, whereby the conveyor belt is circulatingly driven. A first or active-conveying run of the conveyor belt withdraws additional or supplementary sheets, which have been pushed into the movement path or working range of the conveyor belt, from the receiving or storage bins and transports them towards the deposit device. The speed at which these additional or supplementary sheets are transported, is twice the advance speed of the cover element. Thus it is ensured that the additional or supplementary sheets come to rest beneath the cover element.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Uebereinanderlegen von biegsamen Flächengebilden, insbesondere von Blättern und Bogen, gemäss Oberbegriff des Anspruches 1, dem ein interner SA. d. T. zugrunde liegt:The present invention relates to a device for superimposing flexible sheets, in particular sheets and sheets, according to the preamble of claim 1, which an internal SA. d. T. is based on:

Bei Zusammentragmaschinen dieser Art sind unterhalb der in einer Horizontalebene verlaufenden Bewegungsbahn der Sammeleinrichtung hintereinander mehrere Aufnahmefächer für Stapel aus den zusammenzutragenden Blättern angeordnet. Diese Aufnahmefächer sind gegenüber der Vertikalen und somit auch gegenüber der Bewegungsbahn der Sammeleinrichtung geneigt. Mittels Vorschubmechanismen werden bei allen oder nur gewissen Aufnahmefächern einzelne Blätter nach oben vorgeschoben und in den Wirkbereich der Sammeleinrichtung gebracht. Die zwischen einer Ausgangslage und einer Endlage über die Aufnahmefächer hinweg verschiebbare Sammeleinrichtung zieht die vorgeschobenen Blätter von den Stapeln ab, wobei jeweils jedes neu abgezogene Blatt unterhalb der vorangehend abgezogenen Blätter zu liegen kommt. Dabei kann das Abziehen und Fördern der Blätter nur mit der Bewegungsgeschwindigkeit der Sammeleinrichtung erfolgen.In collating machines of this type, a plurality of receiving compartments for stacks of the sheets to be collated are arranged one behind the other below the movement path of the collecting device running in a horizontal plane. These compartments are inclined with respect to the vertical and thus also with respect to the movement path of the collecting device. By means of feed mechanisms, individual sheets are pushed upwards in all or only certain receiving compartments and brought into the effective area of the collecting device. The collecting device, which can be displaced between the starting compartments and an end position, pulls the sheets forwarded from the stacks, each newly removed sheet coming to rest below the sheets previously pulled off. The sheets can only be pulled off and conveyed at the speed of movement of the collecting device.

Aus der US-PS 3 584 865 ist eine andere Art von Zusammentragmaschine bekannt, die ein oberhalb der Aufnahmefächer angeordnetes endloses Förderband aufweist, welches über ortsfeste Umlenkrollen geführt ist und das mit dem den Aufnahmefächern zugekehrten Trum sich in Richtung der Ablage hin bewegend von einem mit einer Umlenkrolle gekoppelten Antrieb umlaufend angetrieben ist. Die mittels der Vorschubmechanismen in den Bereich des Förderbandes vorgeschobenen Blätter werden in geschuppter Form zwischen dem Förderband und den Transportrollen zur Ablage befördert.Another type of collating machine is known from US Pat. No. 3,584,865, which has an endless conveyor belt arranged above the receiving compartments, which is guided over stationary deflection rollers and which moves with the strand facing the receiving compartments in the direction of the storage area from one with a deflection roller coupled drive is rotated. The sheets fed into the area of the conveyor belt by means of the feed mechanisms are conveyed in a scaled form between the conveyor belt and the transport rollers for storage.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, die Einsatzmöglichkeiten einer Vorrichtung der eingangs genannten Art zu erweitern.The present invention is based on the object of expanding the possible uses of a device of the type mentioned at the outset.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des kennzeichnenden Teils des Anspruches 1 gelöst.According to the invention, this object is achieved by the features of the characterizing part of claim 1.

Da die Umlaufgeschwindigkeit des Förderbandes nicht mit der Geschwindigkeit, mit der das Förderband entlang des Förderweges vorwärtsbewegt wird, übereinstimmen muss, ist es möglich, die Fördergeschwindigkeit der übereinanderliegend zur Ablage zu fördernden Blätter, Bogen und dergleichen in gewissen Grenzen an die jeweiligen Gegebenheiten anzupassen.Since the speed of rotation of the conveyor belt does not have to match the speed at which the conveyor belt is moved forward along the conveyor path, it is possible to adjust the conveyor speed of the sheets, sheets and the like to be conveyed one above the other to certain extent to the respective circumstances.

Bei einer bevorzugten und konstruktiv besonders einfachen Ausführungsform liegt das Förderband mit einem zweiten Trum an einem vorzugsweise stationären Bauteil an, und wird bei einer Bewegung entlang der Förderbahn durch Abwälzen dieses zweiten Trums am Bauteil angetrieben. Das hat nun zur Folge, dass die Fördergeschwindigkeit der den Aufnahmefächern entnommenen Flächengebilde doppelt so hoch ist wie die Bewegungsgeschwindigkeit des Förderbandes. Des weiteren erübrigt sich eine eigene Antriebseinheit für das Förderband.In a preferred and structurally particularly simple embodiment, the conveyor belt abuts a preferably stationary component with a second strand, and is driven by rolling this second strand on the component when moving along the conveyor path. The consequence of this is that the conveying speed of the fabrics removed from the receiving compartments is twice as high as the moving speed of the conveyor belt. Furthermore, there is no need for a separate drive unit for the conveyor belt.

Zweckmässigerweise wird oberhalb des Förderbandes eine Auflage für weitere Flächengebilde, welche eine zur Ablage führende Bewegungsbahn festlegt, angeordnet und eine Vorschubeinrichtung zum Bewegen dieser weiteren Flächengebilde entlang dieser Bewegungsbahn zur Ablage vorgesehen. Bei einer solchen Ausführungsform ist es somit auf einfache Weise möglich, Flächengebilde, die nicht aus den unterhalb der Förderbahn angeordneten Aufnahmefächern, sondern von einer andern Quelle, zum Beispiel einem Druckwerk, stammen, mit den den Aufnahmefächern entnommenen Flächengebilden zusammenzubringen, so dass letztere unterhalb der erstgenannten Flächengebilde zu liegen kommen.A support for further flat structures, which defines a movement path leading to storage, is expediently arranged above the conveyor belt and a feed device for moving these further flat structures along this movement path is provided for storage. In such an embodiment, it is thus possible in a simple manner to bring together sheet-like structures which do not come from the receiving compartments arranged below the conveyor track but from another source, for example a printing unit, with the sheet-like structures removed from the receiving compartments, so that the latter below the first-mentioned fabrics come to rest.

Im folgenden wird anhand der Zeichnung ein Ausführungsbeispiel des Erfindungsgegenstandes näher erläutert. Es zeigen rein schematisch :

  • Fig. 1 und 2 in Draufsicht beziehungsweise in Seitenansicht eine Vorrichtung zum Zusammentragen jeweils eines Deckblattes und unterhalb diesem liegenden Beiblättern, und
  • Fig. 3 in einer der Fig. 2 entsprechenden Darstellung die Zusammentragvorrichtung gemäss den Fig. 1 und 2 in einer späteren Arbeitsphase.
An exemplary embodiment of the subject matter of the invention is explained in more detail below with reference to the drawing. It shows purely schematically:
  • 1 and 2 in plan view and in side view of a device for collating a cover sheet and additional sheets lying below it, and
  • Fig. 3 in a representation corresponding to FIG. 2, the collating device according to FIGS. 1 and 2 in a later working phase.

Die in den Figuren dargestellte Zusammentrageinrichtung weist einen Rahmen 1 mit einem Auflagetisch 2 für Deckblätter auf. An diesen Auflagetisch 2, der eine Bewegungsbahn 4 für die Deckblätter 3 festlegt, schliesst eine Ablage 5 an. Diese besteht aus zwei sich gegenüberliegenden, zwischen sich eine Oeffnung 5a bildenden Auflageschienen 6 und 7 sowie einem Anschlag 8. Die Beiblätter 3 werden von einer nicht näher dargestellten Quelle geliefert und auf den Auflagetisch 2 aufgelegt. In Fig. 1 ist mit 3' ein Deckblatt gezeigt, das beispielsweise von einer Druckeinrichtung bekannter Bauart kommt, in welcher dieses Beiblatt 3' zum Beispiel mit einer Versandinformation versehen worden ist. Gegebenenfalls werden die Deckblätter 3 vor dem Auflegen auf den Auflagetisch 2 zugeschnitten.The collating device shown in the figures has a frame 1 with a support table 2 for cover sheets. A tray 5 is connected to this support table 2, which defines a movement path 4 for the cover sheets 3. This consists of two opposing support rails 6 and 7 forming an opening 5a between them and a stop 8. The supplementary sheets 3 are supplied by a source, not shown, and placed on the support table 2. In Fig. 1, 3 'shows a cover sheet which comes, for example, from a printing device of a known type in which this supplementary sheet 3' has been provided with shipping information, for example. If necessary, the cover sheets 3 are cut to size on the support table 2.

Des weiteren ist eine Kolben-Zylindereinheit 9 vorhanden, deren Zylinder 10 liegend am Rahmen 1 befestigt ist.There is also a piston-cylinder unit 9, the cylinder 10 of which is attached to the frame 1 in a lying position.

Mit der Kolbenstange 11 dieser Kolben-Zylindereinheit 9 ist ein Verbindungsstück 12 verbunden, das mittels einer sich in Längsrichtung der Kolben-Zylindereinheit 9 erstreckenden Führungsstange 13 längsgeführt ist. Mit diesem Verbindungsstück 12 ist ein Querträger 14 verbunden, der an seinem freien Ende einen Ausleger 15 (Fig. 1) trägt. An diesem Ausleger 15 ist ein Stossorgan 16 befestigt, das sich durch eine Oeffnung 17 im Auflagetisch 2 hindurcherstreckt. Sowohl der Querträger 14 wie auch der Ausleger 15 verläuft unterhalb des Auflagetisches 2. Am Stossorgan 16 ist ferner drehbar eine Abstützrolle 18 gelagert, die auf der Oberseite des Auflagetisches 2 aufliegt.A connecting piece 12 is connected to the piston rod 11 of this piston-cylinder unit 9 and is guided longitudinally by means of a guide rod 13 extending in the longitudinal direction of the piston-cylinder unit 9. With this connecting piece 12, a cross member 14 is connected, which carries a boom 15 (Fig. 1) at its free end. On this boom 15, a pushing member 16 is attached, which extends through an opening 17 in the support table 2. Both the cross member 14 and the boom 15 run below the support table 2. A support roller is also rotatable on the pushing member 16 18 stored, which rests on the top of the support table 2.

Seitlich des Querträgers 14 ist an diesem eine Halterung 19 für zwei parallel zueinander verlaufende Blattfederelemente 20 und 21 (Fig. 1) angebracht. Diese Blattfederelemente 20, 21 tragen an jedem Ende einen Lagerungsteil 22 für zwei Umlenkrollen 23 und 24. Von diesen beiden Lagerungsteilen 22 ist nur in Fig. 2 der Lagerungsteil für die Umlenkrolle 23 dargestellt. Ueber diese Umlenkrollen 23, 24 ist ein endloses Förderband 25 geführt. Der obere Trum 25b dieses Förderbandes 25 liegt an der Unterseite des Auflagetisches 2 an und wird durch die Blattfederelemente 20, 21 an den Auflagetisch 2 angedrückt. Der gegenüberliegende Trum 25a bildet den förderwirksamen Trum des Förderbandes 25.A bracket 19 for two leaf spring elements 20 and 21 (FIG. 1) running parallel to one another is attached to the side of the cross member 14. These leaf spring elements 20, 21 carry a bearing part 22 for two deflecting rollers 23 and 24 at each end. Of these two bearing parts 22, only the bearing part for the deflecting roller 23 is shown in FIG. 2. An endless conveyor belt 25 is guided over these deflection rollers 23, 24. The upper run 25b of this conveyor belt 25 lies against the underside of the support table 2 and is pressed against the support table 2 by the leaf spring elements 20, 21. The opposite strand 25a forms the effective conveyor strand of the conveyor belt 25.

Unterhalb der Bewegungsbahn 4 für die Deckblätter 3 und auch unterhalb des Förderbandes 25 ist eine Förderbahn 26 angeordnet, die sich parallel zur Bewegungsbahn 4 erstreckt. Diese Förderbahn 26 wird durch parallel zueinander angeordnete Rollen 27 gebildet, die auf nur schematisch dargestellten Federn 28 abgestützt sind. Unterhalb dieser Förderbahn 26 sind Aufnahmefächer 29, 30 und 31 zur Aufnahme von Stapeln 32, 33, 34 aus Zusatz- oder Beiblättern 35, 36 bzw. 37 angeordnet. Diese Zusatz- oder Beiblätter 35, 36, 37 können beispielsweise Anzeige- und Reklameblätter für den Aushang an Verkaufsstellen sein. Die Aufnahmefächer 29, 30, 31, in die herausnehmbare. Ladeeinsätze eingesetzt sind, stehen aufrecht, sind jedoch gegenüber der Vertikalen etwas geneigt. Jedem Aufnahmefach 29, 30, 31 ist ein Vorschubmechanismus 38, 39 bzw. 40 für die Beiblätter 35, 36, 37 zugeordnet. Jeder dieser Vorschubmechanismen 35, 36, 37 weist eine Kolben-Zylindereinheit 41, 42 bzw. 43 auf, deren Kolbenstange 44, 45 bzw. 46 eine Gummiwalze 47, 48 bzw. 49 trägt. Diese Gummiwalzen 47, 48, 49 können einen bei der Einfahrbewegung der Kolbenstangen 44, 45, 46 wirksamen Freilauf aufweisen. Beim Ausfahren der Kolbenstangen 44, 45, 46 wird jeweils das oberste Beiblatt 35', 36' bzw. 37' nach oben in den Wirkbereich des förderwirksamen Trums 25a des Förderbandes 25 vorgeschoben. Durch oberhalb der Aufnahmefächer 29, 30, 31 angeordnete Leitelemente 50, 51 bzw. 52 werden die vorgeschobenen Beiblätter 35, 36, 37 etwas in Vorschubrichtung A umgelenkt.A conveyor track 26, which extends parallel to the movement track 4, is arranged below the movement track 4 for the cover sheets 3 and also below the conveyor belt 25. This conveyor track 26 is formed by mutually parallel rollers 27 which are supported on springs 28, which are only shown schematically. Arranged below this conveyor track 26 are receiving compartments 29, 30 and 31 for receiving stacks 32, 33, 34 made of additional or additional sheets 35, 36 and 37, respectively. These additional or supplementary sheets 35, 36, 37 can, for example, be advertising and advertisement sheets for display at sales outlets. The receiving compartments 29, 30, 31, in the removable. Loading inserts are upright, but are slightly inclined to the vertical. A feed mechanism 38, 39 and 40 for the supplementary sheets 35, 36, 37 is assigned to each receiving compartment 29, 30, 31. Each of these feed mechanisms 35, 36, 37 has a piston-cylinder unit 41, 42 and 43, the piston rod 44, 45 and 46 of which carries a rubber roller 47, 48 and 49. These rubber rollers 47, 48, 49 can have a freewheel which is effective when the piston rods 44, 45, 46 move in. When the piston rods 44, 45, 46 are extended, the uppermost supplementary sheet 35 ', 36' or 37 'is pushed upwards into the effective area of the conveyor-active strand 25a of the conveyor belt 25. By means of guide elements 50, 51 and 52 arranged above the receiving compartments 29, 30, 31, the inserted supplementary sheets 35, 36, 37 are deflected somewhat in the feed direction A.

Die Kolben-Zylindereinheiten 41, 42 und 43 können wahlweise angesteuert werden, so dass für jeden Zusammentragvorgang die gewünschte Zahl und Art von Beiblättern 35, 36, 37 vorgeschoben und mitgenommen werden kann.The piston-cylinder units 41, 42 and 43 can be optionally controlled so that the desired number and type of supplementary sheets 35, 36, 37 can be advanced and taken with them for each collating operation.

Die in den Figuren 1 bis 3 gezeigte Zusammentrageinrichtung arbeitet nun wie folgt :The collating device shown in FIGS. 1 to 3 now works as follows:

In den Figuren 1 und 2 ist sowohl das Stossorgan 16, wie auch das Förderband 25 in der hinteren Endlage gezeigt. Die Kolbenstange 11 ist dabei vollständig ausgefahren. Auf dem Auflagetisch 2 liegt ein Deckblatt 3, das nun mit Beiblättern 35, 36, 37 zusammengebracht werden soll. Durch Ansteuerung der Kolben-Zylindereinheiten 41, 42, 43 werden die gewünschten Beiblätter 35', 36' bzw. 37' vorgeschoben. Im in der Fig. 2 dargestellten Fall wird nur ein Beiblatt 35' benötigt, das mit seinem vorderen Ende in den Bewegungspfad des Förderbandes 25 hineinragt. Durch Einfahren der Kolbenstange 11 in Richtung des Pfeiles B wird nun sowohl das Stossorgan 16 wie auch das Förderband 25 in Richtung des Pfeiles A bewegt. Das Stossorgan 16 schiebt dabei das auf dem Auflagetisch 2 aufliegende Deckblatt 3 gegen die Ablage 5. Der, wie bereits erwähnt, an die Unterseite des stationären Auflagetisches 2 angedrückte obere Trum 25b des Förderbandes 25 wälzt sich nun am Auflagetisch 2 ab, wodurch das Förderband 25 umlaufend angetrieben wird. Der förderwirksame Trum 25a des Förderbandes 25 bewegt sich somit ebenfalls in Richtung des Pfeiles A. Beim Vorbeilaufen des Förderbandes 25 am vorgeschobenen Beiblatt 35' zieht der förderwirksame Trum 25a dieses Beiblatt 35' vom Stapel 32 ab und nimmt ihn (und allenfalls weitere vorgeschobene Beiblätter 36' und 37') mit. Da das Förderband 25 einerseits mit der durch die Einfahrgeschwindigkeit der Kolbenstange 11 festgelegten Vorschubgeschwindigkeit vorwärtsbewegt wird und andererseits mit ebenfalls dieser Vorschubgeschwindigkeit umläuft, werden die Beiblätter 35', 36', 37' doppelt so rasch vorgeschoben wie das Deckblatt 3. Somit ist sichergestellt, dass die Beiblätter 35', 36', 37' zumindest gleichzeitig mit oder gar vor dem Deckblatt 3 zur Ablage 5 gelangen, obwohl diese Beiblätter 35', 36', 37' einen längeren Weg zurückzulegen haben als das Deckblatt 3. Dies bedeutet, dass das Deckblatt 3 wie gewünscht auf die übereinanderliegend gesammelten Beiblätter 35', 36', 37' zu liegen kommt, wie das aus Figur 3 hervorgeht, in der das Stossorgan 16 und das Förderband 25 in ihrer vorderen Endlage dargestellt sind. Der Anschlag 8 sorgt dafür, dass die übereinanderliegenden Blätter 3 und 35' mit ihren vorlaufenden Kanten aufeinander ausgerichtet sind.FIGS. 1 and 2 show both the pushing element 16 and the conveyor belt 25 in the rear end position. The piston rod 11 is fully extended. On the support table 2 there is a cover sheet 3 which is now to be brought together with additional sheets 35, 36, 37. By actuating the piston-cylinder units 41, 42, 43, the desired supplementary sheets 35 ', 36' and 37 'are advanced. In the case shown in FIG. 2, only one additional sheet 35 'is required, which protrudes with its front end into the path of movement of the conveyor belt 25. By retracting the piston rod 11 in the direction of arrow B, both the pushing element 16 and the conveyor belt 25 are now moved in the direction of arrow A. The pushing element 16 pushes the cover sheet 3 lying on the support table 2 against the tray 5. As already mentioned, the upper run 25b of the conveyor belt 25 pressed against the underside of the stationary support table 2 now rolls on the support table 2, whereby the conveyor belt 25 is driven continuously. The conveyor-effective strand 25a of the conveyor belt 25 thus also moves in the direction of arrow A. When the conveyor belt 25 passes the advanced sheet 35 ', the conveyor-active strand 25a pulls this sheet 35' off the stack 32 and takes it (and possibly further advanced sheets 36 'and 37') with. Since the conveyor belt 25 is moved on the one hand at the feed speed determined by the retraction speed of the piston rod 11 and on the other hand also rotates at this feed speed, the supplementary sheets 35 ', 36', 37 'are fed twice as fast as the cover sheet 3. This ensures that the supplementary sheets 35 ', 36', 37 'arrive at the tray 5 at least simultaneously with or even in front of the cover sheet 3, although these supplementary sheets 35', 36 ', 37' have to travel a longer distance than the cover sheet 3. This means that the Cover sheet 3, as desired, comes to lie on the supplementary sheets 35 ', 36', 37 'collected one above the other, as can be seen from FIG. 3, in which the pushing element 16 and the conveyor belt 25 are shown in their front end position. The stop 8 ensures that the sheets 3 and 35 'lying one above the other are aligned with one another with their leading edges.

Durch Ausfahren der Kolbenstange 11 werden Stossorgan 16 und Förderband 25 wieder in die in den Figuren 1 und 2 dargestellte hintere Endlage verbracht, worauf ein erneutes Zusammentragen von Deckblatt 3' und Beiblättern 35, 36, 37 erfol- gen kann.By extending the piston rod 11 ejecting member 16 and conveyor belt 25 are brought back into the position shown in Figures 1 and 2, rear end position, can gen ol followed by a re-gathering of cover sheet 3 'and supplementary sheets 35, 36, 37 he f.

Die in der Ablage 5 übereinanderliegenden Blätter 3 und 35' werden nun auf nicht näher dargestellte Weise durch die Oeffnung 5a hindurch nach unten gestossen und auf einen unterhalb der Auflage 5 vorbeilaufenden Druckproduktestapel aufgelegt. Es versteht sich jedoch, dass die übereinanderliegenden Blätter 3, 35' auch auf andere Weise von der Ablage 5 entfernt werden können.The sheets 3 and 35 'lying one above the other in the tray 5 are then pushed downward through the opening 5a in a manner not shown in any more detail and placed on a stack of printed products passing under the pad 5. However, it goes without saying that the sheets 3, 35 ′ lying one above the other can also be removed from the deposit 5 in another way.

Auf die beschriebene Weise lassen sich auch für andere Zwecke Blätter zusammentragen. So st es beispielsweise möglich, die zusammengeragenen Blätter 3, 35, 36, 37 zu heften oder zu binden oder auf andere Weise miteinander zu verbinden. Falls erforderlich, können mehr als drei Aufnahmefächer vorgesehen werden.In the manner described, leaves can also be collected for other purposes. For example, it is possible to staple or bind the collated sheets 3, 35, 36, 37 or to connect them to one another in some other way. If necessary, more than three compartments can be provided.

Die beschriebene Vorrichtung hat den Vorteil, dass bei gleichbleibender Art der Beiblätter 35, 36, 37-Deckblätter 3 unterschiedlicher Art oder unterschiedlicher Bedruckung verwendet werden können. Es können somit Endprodukte hergestellt werden, die sich in der Art des Deckblattes 3 voneinander unterscheiden. Falls dies nicht erforderlich ist, so kann auf diese Deckblätter 3 und damit auch auf das Stossorgan 12 verzichtet werden. Dies würde bedeuten, dass nur Blätter 35, 36, 37 aus den Aufnahmefächern 29, 30, 31 auf die beschriebene Weise mittels des Förderbandes 25 zusammengetragen werden.The device described has the advantage that, with the same type of supplementary sheets 35, 36, 37 cover sheets 3, different types or different printing can be used. It is thus possible to produce end products which differ from one another in the type of cover sheet 3. If this is not necessary, these cover sheets 3 and thus also the pushing element 12 can be dispensed with. This would mean that only sheets 35, 36, 37 from the receiving compartments 29, 30, 31 are brought together in the manner described by means of the conveyor belt 25.

Die beschriebene Vorrichtung kann selbstverständlich in verschiedenen Teilen anders als wie gezeigt ausgebildet werden. So ist es beispielsweise möglich, das Förderband 25 mehrteilig auszubilden, das heisst mehrere Bändchen nebeneinander anzuordnen.The described device can of course be designed in different parts differently than shown. For example, it is possible to design the conveyor belt 25 in several parts, that is to say to arrange a plurality of tapes next to one another.
