Vorrichtung und Verfahren zum Ablegen von Signaturen oder FalzproduktenDevice and method for storing signatures or folded products
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Ablegen von Signaturen oder Falzprodukten gemäß den Ansprüchen 1 und 12.The invention relates to a device and a method for storing signatures or folded products according to claims 1 and 12.
Die DE 38 27 701 A1 beschreibt eine gattungsgemäße Vorrichtung zum schuppenförmi gen Ablegen von Druckprodukten für eine Ro l lenrotat i onsdruckmaschi ne . Diese Vorrichtung besteht im wesentlichen aus einem Schaufelrad in das ein feststehender Ausstreifer eingrei ft, Luftdüsen zur Beeinflussung des Abbremsvo rgange s , Luftdüsen zur Beeinflussung des Bes c h leuni gungsVorganges beim Ablegen, einer Anzahl von Transportwalzen und einem Förderband. Der feststehende Ausstreifer bremst ein in einer Tasche des Schaufelrades liegendes Produkt ab, wodurch dieses aus dem Schaufelrad gefördert wird. Nachdem das Produkt tei lweise aus der Tasche gestreift wurde, wird ein hinteres Ende des Produktes von den Transportwalzen erfaßt und auf Geschwindigkeit des Transportbandes beschleunigt. Nachtei lig an dieser Vorrichtung ist, daß die Transportwalzen zum Beschleunigen zuerst am offenen Ende des Produktes angreifen und damit das Produkt "schieben". Dadurch kann das Produkt ausknicken und beschädigt werden.DE 38 27 701 A1 describes a device of the generic type for depositing printed products in the form of scales for a rotary printing press. This device consists essentially of a paddle wheel into which a stationary stripper engages, air nozzles to influence the braking processes, air nozzles to influence the loading process during depositing, a number of transport rollers and a conveyor belt. The stationary stripper brakes a product lying in a pocket of the paddle wheel, whereby it is conveyed out of the paddle wheel. After the product has been partially removed from the bag, a rear end of the product is gripped by the transport rollers and accelerated to the speed of the conveyor belt. Nachtei lig on this device is that the transport rollers for acceleration first attack the open end of the product and thus "push" the product. This can cause the product to buckle and to be damaged.
Nachtei lig ist weiterhin, daß der zum präzisen Bremsen und Beschleunigen der Produkte erforderliche Luftdruck nicht nur von der Geschwindigkeit sondern auch von der Massenträgheit und der Oberf lächenbeschaffenhei t der Druckprodukte bestimmt wird und an diese jewei ls angepaßt werden muß.Nachtei lig is furthermore that the air pressure required for precise braking and acceleration of the products is determined not only by the speed but also by the inertia and the surface quality of the printed products and must be adapted to these.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Ablegen von Signaturen bzw. Falzprodukten auf einer bewegbaren Ablage zu schaffen.The invention has for its object to provide a device for storing signatures or folded products on a movable shelf.
Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung und ein Verfahren mit den Merkmalen der kennzeichnenden Tei le der Ansprüche 1 und 12 gelöst.This object is achieved by an apparatus and a method with the features of the characterizing parts of claims 1 and 12.
In vortei lhafter Weise erfolgt ein Ausstreifen von Produkten aus einem Schaufelrad in zwei Stufen: Zuerst wird das Produkt mittels eines feststehenden Ausstreifers annähernd bis zum Sti llstand in Umfangsrichtung abgebremst und somit tei lweise aus der Tasche des Schaufelrades geschoben. Anschließend beschleunigt ein umlaufender, an einem Anfang des Produktes angreifender Ausstreifer das Produkt auf annähernd Transportgeschwindigkeit der Transportbänder, Durch dieses zweistufige Ausstreifen des Produktes aus der Tasche treten folgende Vortei le auf: Feststehende Ausstreifer üben kaum Druckkräfte in radialer Richtung des Schaufelrades aus, wodurch ein schnelles reibungsarmes Ausstreifen des Produktes ohne nennenswerte Verformung erfolgt. Durch entsprechende Anstellung des feststehenden Ausstreifers kann eine hohe Differenzgeschwindigkeit zwischen Schaufe l i nnense i te und aufliegendem Produkt erzeugt werden. Dadurch kann der Ausstrel fVorgang innerhalb eines relativ kurzen Intervalles erfolgen. Weiterhin können dadurch längere Fache rschaufe In verwendet werden, die das Druckprodukt während der Fächerdrehung besser halten. Umlaufende Ausstreifer ermöglichen durch ihre Form und Anstellung ein sanftes, reibschlüssiges Beschleunigen des Produktes nahezu auf Transportgeschwindigkeit der Transportbänder.Advantageously, products are stripped out of a paddle wheel in two stages: First, the product is braked in the circumferential direction by means of a fixed scraper approximately to the level and thus partially pushed out of the pocket of the paddle wheel. Subsequently, a rotating scraper, which attacks the beginning of the product, accelerates the product to approximately the transport speed of the conveyor belts.This two-stage stripping of the product from the pocket gives rise to the following advantages: The product is spread out without friction and without any noteworthy deformation. Appropriate adjustment of the fixed scraper enables a high differential speed to be generated between the inside of the blade and the product lying on it. This enables the process to be carried out within a relatively short interval. In addition, longer tray inlets can be used, which hold the printed product better during the tray rotation. Circumferential scrapers enable the product to be gently, frictionally accelerated due to their shape and position, almost at the transport speed of the conveyor belts.
Durch Ändern des Verhältnisses derBy changing the ratio of the
Umfangsgeschwindigkeiten von Schaufelrad und umlaufenden Ausstreifer, z. B. mittels eines vom Schaufelrad unabhängigen Antrieb, ist ein variabler Abstand, z. B. Schuppenabstand, der abgelegten Produkte möglich. Mit einem radförmigen, mitlaufenden Ausstreifer ist es in vortei lhafter Weise möglich, die abgelegten Produkte zwischen bandförmigen Ausstreifer und einem nachfolgenden Transportband zu klemmen. Damit werden die Produkte auf dem Transportband fixiert und ein Verrutschen vermieden, was eine gute Qualität des Schuppenstromes gewährleistet.Circumferential speeds of the paddle wheel and rotating stripper, e.g. B. by means of a drive independent of the paddle wheel, a variable distance, z. B. scale distance, the stored products possible. With a wheel-shaped, moving stripper, it is possible in an advantageous manner to clamp the deposited products between belt-shaped strippers and a subsequent conveyor belt. This fixes the products on the conveyor belt and prevents them from slipping, which ensures good quality of the shingled stream.
Mit einem bandförmigen mitlaufenden Ausstreifer kann der Bereich, in dem die Druckprodukte zwischen Ausstreifer und Transportband eingeklemmt werden, verlängert werden. Die erfindungsgemäße Vorrichtung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.The area in which the printed products are clamped between the scraper and the conveyor belt can be extended with a belt-shaped moving scraper. The device according to the invention is shown in the drawing and is described in more detail below.

This device essentially consists of a paddle wheel 2, fixed strippers 3, rotating strippers 4 The paddle wheel 2 is formed by a plurality of individual disks 7, which are fastened at a distance from one another on a common shaft 8 in a torsionally rigid manner. This shaft 8 is torsionally rigidly connected to a drive wheel 9 and is rotatably supported in rare frames 11, 12.
Jede dieser Scheiben 7 weist eine auf der Welle 8 angeordnete Nabe 13 auf, die mittels radial gerichteter Speichen 14 mit einem ringförmigen Schaufe It rage r 16 verbunden ist. Dieser Schaufe l t rage r 16 ist mit einer im Querschnitt gesehenen sägezahna rt i gen Kontur versehen. An einer Mantelfläche 17 des Schaufelträgers 16 sind Schaufeln 18 radial nach außen weisend, sich annähernd in tangentialer Richtung bezogen auf die Welle 8 erstreckend befestigt. Diese Schaufeln 18 sind in ihrer Längsrichtung leicht gekrümmt und leicht geneigt gegenüber der tangentialen Richtung des Schaufe l t rage rs 16 ausgeführt. In Umfangsrichtung sind diese Schaufeln 18 zueinander beabstandet, sich überlappend befestigt, so daß zwischen einer nach außen weisenden Seite 19 einer in Drehrichtung des Schaufelrades 2 gesehenen nachlaufenden Schaufel 18 und einer nach innen weisenden Seite 21 einer vorlaufenden Schaufel 18 eine Tasche 22 gebildet wird. Diese Tasche 22 weist einen sich zu einem Taschengrund 23 hin verjüngenden Querschnitt auf. Zwischen den einzelnen Scheiben 7 sind gestellfeste, starre Ausstrelfer 3 angeordnet, die rechenartig in das Schaufelrad 2 eingreifen. Diese Ausstreifer 3 sind im vorliegenden Ausführungsbeispiel abgewinkelt, so daß ein erster, im Bereich des Taschengrundes 23 endender Schenkel 24 bezüglich der tangentialen Richtung des Schaufelrades 2 nach innen geneigt angeordnet ist. Ein zweiter Schenkel 26 des Ausstreifers 3 verläuft annähernd parallel zu dem nachgeschalteten Transportband 6.Each of these disks 7 has a hub 13 arranged on the shaft 8, which is connected by means of radially directed spokes 14 to an annular blade It rage r 16. This blade lt rage r 16 is provided with a sawtooth contour seen in cross section. On a lateral surface 17 of the blade carrier 16, blades 18 are attached pointing radially outward, extending approximately in the tangential direction with respect to the shaft 8. These blades 18 are slightly curved in their longitudinal direction and slightly inclined with respect to the tangential direction of the blade lt rage rs 16. In the circumferential direction, these blades 18 are spaced apart from one another and fastened in an overlapping manner, so that a pocket 22 is formed between an outwardly facing side 19 of a trailing blade 18 seen in the direction of rotation of the impeller 2 and an inwardly facing side 21 of a leading blade 18. This pocket 22 has a cross section tapering towards a pocket base 23. Between the individual disks 7, rigid outriggers 3 are arranged, which engage in a rake-like manner in the impeller 2. These strippers 3 are angled in the present embodiment, so that a first leg 24, which ends in the region of the pocket base 23, is arranged inclined inwards with respect to the tangential direction of the impeller 2. A second leg 26 of the stripper 3 runs approximately parallel to the downstream conveyor belt 6.
In Zwischenräumen zwischen beispielsweise den beiden in axialer Richtung des Schaufelrades 2 gesehenen äußeren Scheiben 7 sind zwei umlaufende Ausstreifer 4 angeordnet. Es ist auch möglich nur einen einzigen oder auch eine Vielzahl umlaufender Ausstreifer 4 mit umlaufenden Ausstre i ff lachen 28 vorzusehen. Diese umlaufenden Ausstreifer 4 sind derart verstellbar angeordnet, so daß diese eine Peripherie des ersten Schenkels 24 oder deren virtuelle Verlängerung schneiden, wobei diese um einen überstand a4 über eine Peripherie des ersten Schenkels 24 oder deren virtuelle Verlängerung und einen überstand a5 des zweiten Schenkels 26 des starren Ausstreifers 3 gegen die Produkt i ons ri chtung P des Schaufelrades 2 herausragen.Two circumferential strippers 4 are arranged in spaces between, for example, the two outer disks 7 seen in the axial direction of the impeller 2. It is also possible to provide only a single or also a plurality of rotating strippers 4 with rotating stripes 28. These circumferential strippers 4 are arranged such that they can cut a periphery of the first leg 24 or its virtual extension, which extends by a projection a4 over a periphery of the first leg 24 or its virtual extension and a projection a5 of the second leg 26 of the protruding rigid stripper 3 against the product i on direction P of the impeller 2.
Im vorliegenden ersten Ausführungsbeispiel ist der umlaufenden Ausstreifer 4 als angetriebenes Rad 27 ausgeführt. Dieses Rad 27 weist an seiner Ausstrei ff lache 28, d. h. Mantelfläche 28, einen großen Reibwert auf, weshalb diese Mantelfläche 28 beispielsweise mit einem Kunststoff, z. B. Polyurethan, beschichtet ist. Zwei dieser angetriebenen Räder 27 sind in Zwischenräumen der jeweils beiden äußeren Scheiben 7 des Schaufelrades 2 angeordnet. Diese Räder 27 sind jewei ls derart verstellbar angeordnet, daß zumindest der überstand a4 veränderbar ist. Im vorliegenden Beispiel ist hierzu jedes Rad 27 auf einem Arm 29 eines zweiarmigen Schwenkhebels 31 drehbar gelagert. Dieser Schwenkhebel 31 ist mittels einer Lagerung 32 auf der Welle 8 des Schaufelrades 2 drehbar gelagert, wobei sich ein Achsabstand a1 zwischen Drehachsen 33, 34 von Welle 8 und Rad 27 von beispielsweise a1 = 175 mm ergibt. An einem zweiten Arm 36 des Schwenkhebels 31 greift eine VerStelleinrichtung zum Schwenken des Schwenkhebels 31 und damit zum Einstellen des Überstandes a4 an. Diese VerStelleinrichtung ist im Ausführungsbeispiel als eine Gewindespindel 37 ausgeführt, deren erstes Ende drehbar in einer in dem Arm 36 des Schwenkhebels 31 gelagerten Gewindenuß 38 eingreift und deren zweites Ende drehbar, aber in Längsrichtung der Gewindespindel 37 mittels einer Nuß 39 fest in den Seitengestellen 11, 12 gelagert ist. An diesen Gewindespindeln 37 können selbstverständlich Antriebe, z. B. Schrittmotoren, angeordnet sein, um eine Fernverstellung der Räder 27 zu e rmög liehen.In the present first exemplary embodiment, the rotating stripper 4 is designed as a driven wheel 27. This wheel 27 has at its Ausstrei ff pool 28, ie lateral surface 28, a large coefficient of friction, which is why this lateral surface 28, for example with a plastic, for. B. polyurethane is coated. Two of these driven wheels 27 are in the spaces between the two outer disks 7 the paddle wheel 2 arranged. These wheels 27 are each adjustable so that at least the projection a4 can be changed. In the present example, each wheel 27 is rotatably mounted on an arm 29 of a two-armed pivot lever 31. This pivot lever 31 is rotatably mounted on the shaft 8 of the paddle wheel 2 by means of a bearing 32, with an axial distance a1 between the axes of rotation 33, 34 of the shaft 8 and wheel 27 of, for example, a1 = 175 mm. On a second arm 36 of the pivot lever 31, an adjusting device for pivoting the pivot lever 31 and thus for adjusting the projection a4 acts. In the exemplary embodiment, this adjusting device is designed as a threaded spindle 37, the first end of which rotatably engages in a threaded nut 38 mounted in the arm 36 of the pivoting lever 31 and the second end of which is rotatable, but in the longitudinal direction of the threaded spindle 37 by means of a nut 39 firmly in the side frames 11, 12 is stored. On these threaded spindles 37 drives, of course. B. stepper motors can be arranged to lend a remote adjustment of the wheels 27 to e rmög.
Das Rad 27 weist zum Transportband 6 einen Abstand a2, z. B. a2 = 9 mm, auf, der vorzugsweise kleiner ist als eine Dicke d1, z. B. d1 = 10 mm, eines auszulegenden Produktes 1.The wheel 27 has a distance a2, z. B. a2 = 9 mm, which is preferably smaller than a thickness d1, z. B. d1 = 10 mm, of a product to be designed 1.
Eine Umfangsgeschwindigkeit u27 des Rades 27 ist kleiner als eine Umfangsgeschwindigkeit u2 des Schaufelrades 2, vorzugsweise beträgt das Verhältnis der Umfangsgeschwindigkeit u27 des Rades 27 zur Umfangsgeschwindigkeit u2 des Schaufelrades 2 0,6 bis 0,95, d. h. u27 : u2 = 0,6 bis 0,95. Das Rad 27 dreht ebenso wie das Schaufelrad 2 in Produkt i ons ri chtung P. Hierzu ist als Antrieb im dargestellten ersten Ausführungsbeispiel (Fig. 1, Fig. 2) ein Zwangsantrieb von der Welle 8 des Schaufelrades 2 ausgehend vorgesehen. Die Welle 8 ist beispielsweise mit einer ersten Riemenscheibe 41 mit einem Wirkdurchmesser d41 und das Rad 27 mit einer zweiten Riemenscheibe 42 mit einem Wirkdurchmesser d42, drehsteif verbunden. Mittels eines Riemens 43, z. B. eines Zahnriemens 43, wird die zweite 42 von der ersten Riemenscheibe 41 angetrieben. Anstelle des Riementriebes kann auch ein Kettentrieb oder ein Zahnradgetriebe vorgesehen sein.A peripheral speed u27 of the wheel 27 is smaller than a peripheral speed u2 of the impeller 2, the ratio is preferably The peripheral speed u27 of the wheel 27 to the peripheral speed u2 of the impeller 2 0.6 to 0.95, ie u27: u2 = 0.6 to 0.95. The wheel 27 rotates in the same way as the paddle wheel 2 in the direction of production P. For this purpose, as a drive in the illustrated first exemplary embodiment (FIG. 1, FIG. 2), a positive drive starting from the shaft 8 of the paddle wheel 2 is provided. The shaft 8 is connected, for example, with a first pulley 41 with an effective diameter d41 and the wheel 27 with a second pulley 42 with an effective diameter d42, torsionally rigid. By means of a belt 43, e.g. B. a toothed belt 43, the second 42 is driven by the first pulley 41. Instead of the belt drive, a chain drive or a gear transmission can also be provided.
In einem zweiten Ausführungsbeispiel (Fig. 3) ist jewei ls ein Lagerarm 46 zur Lagerung der beiden Räder 27 unabhängig von der Welle 8 des Schaufelrades 2 auf einer eigenen, in den Seitengestellen 11, 12 befestigten Achse schwenkbar gelagert. Auch hier sind wiederum in axialer Richtung des Schaufelrades 2 gesehen zwei Räder 27 angeordnet. Im folgenden wird nur die Anordnung eines Rades 27 auf einer Seite beschrieben, die zweite Seite ist adäquat ausgeführt:In a second exemplary embodiment (FIG. 3), a bearing arm 46 for mounting the two wheels 27 is pivotably mounted independently of the shaft 8 of the paddle wheel 2 on its own axis fastened in the side frames 11, 12. Here, too, two wheels 27 are again arranged in the axial direction of the impeller 2. In the following, only the arrangement of a wheel 27 on one side is described, the second side is made adequately:
Der Antrieb dieses Rades 27 erfolgt in Abhängigkeit vom Transportband 6. Eine Bänderwalze 48 des Transportbandes 6 weist einen drehzah Lrege Ibaren Antrieb, z. B. einen Drehstrommotor, der zum Schaufelrad 2 synchronisiert ist, und eine Riemenscheibe 49 auf. Von dieser Riemenscheibe 49 führt beispielsweise ein gekreuzter Riemen 51 zu einer auf der Achse 47 frei drehbaren Riemenscheibe 52, von der ein Zahnriemen 53 zu einer mit dem Rad 27 fest verbundenen Riemenscheibe 54 führt. Die Umfangsgeschwindigkeit u4 des umlaufenden Ausstreifers 4 ist damit unabhängig von der Umfangsgeschwindigkeit u2 des Schaufelrades 2 veränderbar.The drive of this wheel 27 takes place in dependence on the conveyor belt 6. A belt roller 48 of the conveyor belt 6 has a speed Lrege Ibaren drive, z. B. a three-phase motor that synchronizes with the impeller 2 and a pulley 49. From this belt pulley 49, for example, a crossed belt 51 leads to a belt pulley 52 which is freely rotatable on the axis 47 and from which a toothed belt 53 leads to a belt pulley 54 which is firmly connected to the wheel 27. The peripheral speed u4 of the rotating stripper 4 can thus be changed independently of the peripheral speed u2 of the impeller 2.
An dem Lagerarm 46 greift eine in einer Gewindenuß 56 gelagerte Gewindespindel 57 an, deren anderes Ende in einer Nuß 58 drehbar, aber in ihrer Längsrichtung ortsfest im Seitengestell 11, 12 befestigt ist. Durch Verdrehen dieser Gewindespindel 57 kann der Lagerarm 46 um die Achse 47 geschwenkt und somit ein überstand a4 zwischen feststehendem Abstreifer 3 und Rad 27 verändert werden .A threaded spindle 57 mounted in a threaded nut 56 engages on the bearing arm 46, the other end of which can be rotated in a nut 58, but is fixed in the longitudinal direction in the side frame 11, 12. By rotating this threaded spindle 57, the bearing arm 46 can be pivoted about the axis 47 and thus an overhang a4 between the fixed scraper 3 and the wheel 27 can be changed.
Bei einem dritten Ausführungsbeispiel ist der umlaufenden Ausstreifer 4 als Ausstreifband 61 ausgeführt. Dazu ist anstelle des Rades 27 des zweiten Ausführungsbeispiel ein Führungsrad 62 auf dem Lagerarm 46 und auf der Achse 47 ein drehbares, mit dem Führungsrad 62 fluchtendes Rad 63 vorgesehen, über diese beiden Räder 62, 63 läuft ein Ausstreifband 61, z. B. ein Flachriemen, zum Ausstreifen der Produkte 1. Die beiden Räder 62, 63 sind derart angeordnet, daß das Ausstreifband 61 annähernd parallel zum Transportband 6 verläuft. Die Produkte 1 sind somit zur Führung zwischen Aus s t re i fband 61 und Transportband 6 einklemmbar. Auch bei diesem Ausführungsbeispiel ist sowohl der überstand a4 zwischen feststehendem Ausstreifer 3 und Ausstreifband 61 als auch der Abstand a4 zwischen Transportband 6 und Ausstreifband 61 veränderbar.In a third exemplary embodiment, the circumferential stripper 4 is designed as a stripper belt 61. For this purpose, instead of the wheel 27 of the second exemplary embodiment, a guide wheel 62 is provided on the bearing arm 46 and on the axis 47 a rotatable wheel 63 aligned with the guide wheel 62 is provided. A stripping belt 61, for example, runs over these two wheels 62, 63. B. a flat belt for stripping out the products 1. The two wheels 62, 63 are arranged such that the stripping belt 61 runs approximately parallel to the conveyor belt 6. The products 1 are thus for guidance between Can be clamped out of strip 61 and conveyor belt 6. In this exemplary embodiment, too, both the protrusion a4 between the stationary stripper 3 and the stripping belt 61 and the distance a4 between the conveyor belt 6 and the stripping belt 61 can be changed.
Anstelle des von dem Schaufelrad 2 oder dem Transportband 6 abhängigen Antriebes für den umlaufenden Ausstreifer 4 ist es selbstverständlich auch möglich diesen Ausstreifer 4 mit einem eigenen, völlig unabhängigen, drehzah l rege Ibaren Antrieb zu versehen. Damit sind die Umfangsgeschwindigkeiten u2, u4, u6 von Schaufelrad 2, Ausstreifer 4 und Transportband 6 unabhängig voneinander regelbar.Instead of the drive for the rotating stripper 4, which is dependent on the paddle wheel 2 or the conveyor belt 6, it is of course also possible to provide this stripper 4 with its own, completely independent, high-speed drive. The peripheral speeds u2, u4, u6 of the paddle wheel 2, stripper 4 and conveyor belt 6 can thus be regulated independently of one another.
Die Funktionsweise der erfindungsgemäßen Vorrichtung wird beispielhaft anhand des zweiten Ausführungsbei spiels beschrieben:The functioning of the device according to the invention is described by way of example with reference to the second exemplary embodiment:
Die Produkte 1 werden durch nicht näher dargestellte Einrichtungen in die Taschen 22 des Schaufelrades 2 geführt. Das Schaufelrad 2 dreht in Produkt i onsri chtung P mit den mit Produkten 1 gefüllten Taschen 22, bis der im Taschengrund 23 vorlaufende Ende 64 der Produkte 1 an den feststehenden Ausstreifer 3 anstößt. Dadurch werden die mit Umfangsgeschwindigkeit u2 des Schaufelrades 2 bewegten Produkte 1 stark in Umfangsrichtung abgebremst. Die Produkte 1 haben nun auf Umfangsrichtung des Schaufelrades 2 bezogen nur noch eine geringe Geschwindigkeit, während das Schaufelrad 2 sich weiterdreht und somit die Produkte 1 aus den Taschen 22 gleiten. Dadurch verringert sich der Abstand a3 zweier aufeinanderfolgender Produkte 1, der durch den Abstand a3 in Umfangsrichtung zweier Taschen 22 vorgegeben ist. Das Produkt 1 wird somit aus der Tasche 22 gefördert, wobei im wesentlichen nur Kräfte in tangentialer Richtung des Schaufelrades 2, also in Längsrichtung der Tasche 22, und nicht in radialer Richtung auftreten. Dabei führt das Produkt 1 durch die Form der Schaufeln 18 auch eine Bewegung in radialer Richtung aus, wodurch sein vorlaufedes Ende 64 nun in Kontakt mit dem umlaufenden Ausstreifer 4 gerät. Der Ausstreifer 4 erfaßt das bezüglich der Transport ri chtung T des Transportbandes 6 ruhende Produkt 1 und beschleunigt es in T ransport ri chtung T annähernd aufThe products 1 are guided into the pockets 22 of the paddle wheel 2 by means not shown in detail. The paddle wheel 2 rotates in product direction P with the pockets 22 filled with products 1 until the end 64 of the products 1 leading in the pocket base 23 abuts the fixed stripper 3. As a result, the products 1 moving at the peripheral speed u2 of the impeller 2 are braked strongly in the peripheral direction. The products 1 now have only a small amount in relation to the circumferential direction of the impeller 2 Speed while the paddle wheel 2 continues to rotate and thus the products 1 slide out of the pockets 22. This reduces the distance a3 between two successive products 1, which is predetermined by the distance a3 in the circumferential direction of two pockets 22. The product 1 is thus conveyed out of the pocket 22, wherein essentially only forces occur in the tangential direction of the paddle wheel 2, that is to say in the longitudinal direction of the pocket 22, and not in the radial direction. The product 1 also executes a movement in the radial direction due to the shape of the blades 18, as a result of which its leading end 64 now comes into contact with the circumferential stripper 4. The stripper 4 detects the product 1, which is stationary with respect to the transport direction T of the conveyor belt 6, and accelerates it approximately in the transport direction T
Transportgeschwindigkeit des Transportbandes 6. Hat das Produkt 1 nahezu die Tasche 22 verlassen, wird es von dem umlaufenden Ausstreifer 4 auf das Transportband 6 gedrückt. Das Transportband 6 fördert die s chuppenförmi g abgelegten Produkte 1 zu nachgeschalteten, nichtdargestellten Verarbeitungseinrichtungen. Der Schuppenabstand der Produkte 1 auf dem Transportband 6 ergibt sich aus dem Verhältnis der nahezu gleichgroßen Umfangsgeschwindigkeit u4 bzw. u6 des umlaufenden Ausstreifers 4 und das Transportbandes 6 zu der Umfangsgeschwindigkeit u2 und Tei lung, d. h. Abstand a3, des Schaufelrades 2. Der Ausstreifer 4 ist derart einstellbar, daß de r Ausstreifer 4 die Produkte 1 gegen das Transportband 6 drückt. Transport speed of the conveyor belt 6. When the product 1 has almost left the pocket 22, it is pressed onto the conveyor belt 6 by the rotating stripper 4. The conveyor belt 6 conveys the scaly-shaped deposited products 1 to downstream, not shown processing devices. The scale distance of the products 1 on the conveyor belt 6 results from the ratio of the almost the same circumferential speed u4 or u6 of the rotating stripper 4 and the conveyor belt 6 to the circumferential speed u2 and parting, ie distance a3, of the paddle wheel 2. The stripper 4 is adjustable so that the r Scraper 4 presses the products 1 against the conveyor belt 6.
