Abstract

The conveyor system has a belt (10) to take the flow of loose and limp products (12) in an overlapping configuration (S) from the transport system (14), for onwards movement. The conveyor belt (10) passes round a deflection drum (16), to form an advancement movement gap (26) between them to take the overlapping product structure (S), with an edge section over the drum on one side. The recirculating path (104) of the transport system (14) runs next to the drum, fitted with grips (20) to grasp the overlapped (S) materials at the edges for onwards movement.

Description

Die vorliegende Erfindung betrifft Fördereinrichtungen für in einer Schuppenformation anfallende, flexible, flächige Gegenstände, gemäss dem Oberbegriff der Ansprüche 1 und 10.The present invention relates to conveyors for in one Dandruff formation, flexible, flat objects, according to the preamble of claims 1 and 10.

Fördereinrichtungen dieser Art sind in der CH-Patentschrift Nr. 559692 und in der entsprechenden US-Patentschrift Nr. 3,877,564 offenbart. Ein endloses umlaufend angetriebenes Förderorgan weist eine Rollenkette und auf die beiden Enden der Gliederbolzen dieser Rollenkette aufgesetzte endlose Gummiprofile auf. Diese bilden eine Auflage für den zu transportierenden Schuppenstrom. Am Anfang und am Ende der Transportstrecke ist das Förderorgan um Kettenräder geführt. An der Kette sind im Abstand hintereinander Führungswagen befestigt, die zwischen den Kettenrädern in Hohlschienen geführt sind. Von jedem der Führungswagen erstrecken sich nach beiden Seiten je ein hülsenförmig ausgebildeter Greiferausleger, an deren freien Enden bewegliche Greiferbacken angelenkt sind. Am Greiferausleger angeordnete feste Backen und die beweglichen Backen sind dazu bestimmt, die Schuppenformation an den beiden seitlichen Kanalabschnitten zu fassen. Ein Transportband ist dazu bestimmt, die Schuppenformation in freier Auflage dem Förderer zuzuführen, wobei sich das Förderorgan im Bereich des Kettenrades an die freie Flachseite der Schuppenformation anlegt. Dem Transportband ist unmittelbar ein, in der Art eines Kettenrollenbandes ausgeführtes, umlaufend angetriebenes, weiteres Förderorgan nachgeschaltet, welches zusammen mit dem um das Kettenrad umgelenkte Förderorgan einen Förder- und Umlenkspalt für die Schuppenformation bildet. Im Bereich des Förderspaltes werden dann die betreffenden Greifer für den Weitertransport der Schuppenformation geschlossen. Am Ende der Förderstrecke ist die Übergabe an ein weiteres Transportband symmetrisch zur Einrichtung am Anfang der Förderstrecke ausgebildet. In der Umlenkung um das Kettenrad am Anfang und am Ende der Förderstrecke bildet das endlose Förderorgan selber die Auflage für die Schuppenformation. Dieses muss somit im Bereich der Kettenräder als auch zwischen diesen mit der gleichen Geschwindigkeit angetrieben sein wie die Transportbänder und überdies müssen die Greifer die Produkte in der Ebene des Förderorgans festklemmen, um Verletzungen der Gegenstände zu vermeiden. Die bekannte Fördereinrichtung benötigt insbesondere im Bereich der Umlenkung erheblich Platz und setzt enge Grenzen bezüglich des Aufbaus des Förderers.Conveyors of this type are in CH Patent No. 559692 and in the corresponding U.S. Patent No. 3,877,564. An endless one revolving driven conveyor has a roller chain and the two ends of the link pins of this roller chain put on endless Rubber profiles. These form a support for the item to be transported Scale flow. The conveyor is at the beginning and end of the transport route led around sprockets. The chain are spaced one behind the other Carriage fixed between the sprockets in hollow rails are led. From each of the carriages extend to on both sides a sleeve-shaped gripper arm, on the other free ends of movable gripper jaws are articulated. On the grab arm arranged fixed jaws and the movable jaws are designed to the scale formation on the two lateral channel sections to understand. A conveyor belt is designed to keep the scale formation in free circulation to the conveyor, with the funding body in the area of the chain wheel on the free flat side of the scale formation. The conveyor belt is directly in the manner of a chain roller belt executed, rotating driven, further conveyor downstream, which together with the one deflected around the sprocket Conveyor organ a conveying and deflection gap for the scale formation forms. The grippers in question are then in the area of the conveyor gap closed for further transport of the scale formation. At the end of The transfer route is symmetrical when it is transferred to another conveyor belt trained to set up at the beginning of the conveyor line. In the Redirection around the sprocket at the beginning and end of the conveyor line the endless funding body itself forms the support for the scale formation. This must be in the area of the sprockets as well as between be driven at the same speed as that Conveyor belts and moreover, the grippers have to level the products of the conveyor element to prevent injuries to the objects. The known conveyor device is particularly required in the area the redirection takes up a lot of space and places tight limits on the structure of the sponsor.

Es ist deshalb eine Aufgabe der vorliegenden Erfindung, eine gattungsgemässe Fördereinrichtung zu schaffen, die bei kleinem Platzbedarf eine grosse Flexiblität im Aufbau des Förderers zulässt.It is therefore an object of the present invention, a generic To create conveyor that takes up a small amount of space allows great flexibility in the structure of the conveyor.

Diese Aufgabe wird mit einer gattungsgemässen Fördereinrichtung gelöst, die die Merkmale im Kennzeichen des Anspruchs 1 aufweist. Die Umlenkung erfolgt um eine Trommel, die von der Umlaufbahn der Greifer getrennt ist. Im Bereich der Umlenkung können somit die Greifer bezüglich der Schuppenformation eine unterschiedliche Geschwindigkeit aufweisen; der Förderer mit den Greifern ist nicht an die Umlenkung gebunden, was unterschiedliche Ausbildungsformen des Förderers zulässt. Die Fördereinrichtung kann somit auf einfache Art und Weise an die unterschiedlichsten Bedürfnisse angepasst werden. This task is solved with a generic conveyor device, which has the features in the characterizing part of claim 1. The redirection takes place around a drum that is separated from the orbit of the grippers is. In the area of the deflection, the grippers can thus the scale formation has a different speed; the conveyor with the grippers is not tied to the redirection, what permits different forms of training of the sponsor. The conveyor can thus easily be sent to the most varied of people Needs to be adjusted.

The sprocket 38 is encompassed by a drive chain 42 which by a drive motor, not shown, is driven in the direction of rotation D.

Das Abtriebsrad 40 treibt über einen Antriebsriemen 44 ein auf einer Zwischenwelle 46 angeordnetes Antriebsrad 48 an. Die Zwischenwelle 46 verläuft in Zuführrichtung Z stromaufwärts der Umlenktrommel 16 in Richtung rechtwinklig zur Zuführrichtung Z zwischen den Trumen der Bändchen 22. Auf ihr ist ein drehfest mit dem Antriebsrad 48 verbundenes Zwischenrad 50 angeordnet, das über einen zur Drehrichtungsumkehr kreuzend verlaufendes Antriebsband 52 mit einem weiteren Antriebsrad 54 verbunden ist. Dieses sitzt drehfest auf einer Antriebswelle 56, auf welche am stromaufwärts gelegenen Ende des Transportbandes 10 die Umlenkräder 58 für die Bändchen 22 aufgekeilt sind. Die fünf die Umlenktrommel 16 mit ihrem aktiven Trum umgreifenden Bändchen 22 laufen etwa in vertikaler Richtung gegen oben von der Umlenktrommel 16 ab und sind um frei drehbar gelagerte obere Umlenkräder 60 geführt. Von diesen verläuft der Rücktrum in vertikaler Richtung gegen unten zu unteren Umlenkrädern 62, von wo er zu den weiteren Antriebsrädern 54 zurückverläuft. Die unteren Umlenkräder 62 sind frei drehbar auf einer am Maschinengestell 32 angeordneten Achse gelagert. Auf dieser Achse sind auch die stromabwärts gelegenen Umlenkräder 62 für die seitlich ausserhalb der Umlenktrommel 16 angeordneten zwei Bändchen 22 gelagert.The driven wheel 40 drives via a drive belt 44 on one Intermediate shaft 46 arranged drive wheel 48. The intermediate shaft 46 runs in the feed direction Z upstream of the deflection drum 16 in the direction perpendicular to the feed direction Z between the strands of the ribbon 22. There is an idler gear connected to the drive gear 48 in a rotationally fixed manner 50 arranged, the one crossing to reverse the direction of rotation Drive belt 52 connected to another drive wheel 54 is. This sits rotatably on a drive shaft 56, on which upstream end of the conveyor belt 10, the deflection wheels 58 for the ribbons 22 are wedged. The five the pulley 16 with their active strands 22 encompass approximately run in the vertical direction towards the top of the deflection drum 16 and are freely rotatable mounted upper deflection wheels 60 out. The back run runs from these in the vertical direction towards the bottom to lower guide wheels 62, from where it runs back to the other drive wheels 54. The lower Deflection wheels 62 are freely rotatable on one on the machine frame 32 arranged axis mounted. They are also on this axis downstream deflection wheels 62 for the side outside the Deflection drum 16 arranged two tapes 22 mounted.

Die oberen Umlenkräder 60 sind auf einer Achse 64 frei drehbar gelagert, die an einem Schwenkhebel 66 angeordnet ist. Letzterer ist am Maschinengestell 32 benachbart zur Achse der unteren Umlenkräder 62 schwenkbar gelagert und von einer in der Fig. 1 mit ausgezogenen Linien gezeigten Umlenkstellung in Richtung des Pfeiles U in eine Durchlaufstellung 68 verbringbar, in welcher, wie in der Fig. 1 strichpunktiert angedeutet, das aktive Trum des Transportbandes 10 die Umlenktrommel 16 nicht mehr oder nur noch in einem viel geringeren Mass umgreift. Dadurch kann die Fördereinrichtung in der Art einer Weiche, beispielsweise zum Ausscheiden von Makulatur, verwendet werden.The upper deflection wheels 60 are freely rotatable on an axis 64, which is arranged on a pivot lever 66. The latter is on the machine frame 32 pivotable adjacent to the axis of the lower guide wheels 62 stored and from a deflection position shown in FIG. 1 with solid lines can be brought into a continuous position 68 in the direction of arrow U, in which, as indicated by dash-dotted lines in FIG. 1, the active Run of the conveyor belt 10, the deflection drum 16 no longer or only encompasses to a much lesser extent. This allows the conveyor in the manner of a switch, for example for the elimination of Waste, to be used.

Zwischen der Umlenktrommel 16 und dem Kettenrad 38 sitzt auf der Antriebswelle 34 drehfest ein Nockenrad 70. Dieses ist von einer im Querschnitt C-förmigen Führungsschiene 72 umgriffen, die im Bereich des Nockenrades 70 Klothoidenform aufweist. Im Bereich des Nockenrades 70 ist der die Seitenschenkel 74 der Führungsschiene 72 verbindende Boden durchgriffen, so dass das Nockenrad 70 in das Innere der in radialer Richtung gegen aussen offenen Führungsschiene 72 eingreifen kann.Between the deflection drum 16 and the sprocket 38 sits on the drive shaft 34 rotates a cam gear 70. This is of a cross-section C-shaped guide rail 72 encompassed in the area of Cam wheel has 70 clothoid shape. In the area of the cam gear 70 is the bottom connecting the side legs 74 of the guide rail 72 penetrated so that the cam gear 70 in the interior of the radial direction can engage against the guide rail 72 open to the outside.

In der Führungsschiene 72 sind hintereinander Tragkörper 76 angeordnet, welche einerseits über Führungsräder 78 im Innern der Führungsschiene 72 und andererseits mittels weiterer Führungsräder 80 an den einander zugewandten Enden der aufeinander zu gebogenen Seitenschenkel 74 geführt sind. Auf der den Führungsrädern 80 gegenüberliegenden und somit dem Nockenrad 70 zugewandten Seite weisen die Tragkörper 76 zahnartige Vorsprünge und Vertiefungen auf, die dazu bestimmt sind, mit gegengleich geformten Zähnen des Nockenrades 70 zusammenzuwirken. Die Tragkörper 76 werden somit mittels des Nockenrades 70 im Bereich der Umlenkung angetrieben. Stromabwärts des Nockenrades 70 erfolgt der Antrieb stossend infolge des stirnseitigen Aneinanderanliegens der Tragkörper 76. An jedem n-ten, beispielsweise vierten Tragkörper 76, ist ein Greifer 20 angeordnet. Dazu sitzt auf den Achsen für die Führungsräder 80 ein Support 84, von dem ein rechtwinklig zur Förderrichtung F verlaufender Ausleger 86 absteht. Auf diesem ist auf der dem Support 84 und somit dem Tragkörper 76 abgewandten, in Richtung gegen aussen freiliegenden Seite, eine feste Greiferzunge 88 angeordnet. Diese kann mit einem Reibbelag versehen sein.Carrier bodies 76 are arranged one behind the other in the guide rail 72, which, on the one hand, via guide wheels 78 inside the guide rail 72 and on the other hand by means of further guide wheels 80 on the facing one another Ends of the side legs 74 bent towards each other are. On the opposite of the guide wheels 80 and thus the The cam body 70 facing side, the support body 76 tooth-like Projections and recesses that are intended to be counterpared shaped teeth of the cam wheel 70 cooperate. The supporting body 76 are thus by means of the cam wheel 70 in the region of the deflection driven. The drive takes place downstream of the cam wheel 70 pushing due to the abutment of the supporting bodies 76. On every nth, for example fourth support body 76, there is a gripper 20 arranged. For this purpose sits on the axles for the guide wheels 80 Support 84, one of which is perpendicular to the conveying direction F. Boom 86 protrudes. On this is on the support 84 and thus facing away from the support body 76, in the direction exposed to the outside Side, a fixed gripper tongue 88 is arranged. This can be done with a friction lining be provided.

Auf dem Ausleger 68 sitzt auf dessen von der Umlenktrommel 16 abgewandten Ende ein Greifergehäuse 90, an dem eine wellenartig geformte, federartige, bewegliche Greiferzunge 92 um eine in Förderrichtung F verlaufende Schwenkachse 94 gelagert ist. Eine ebenfalls am Greifergehäuse 90 befestigte, blattfederartig ausgebildete Offenhaltefeder 96 wirkt auf die bewegliche Greiferzunge 92 in deren Öffnungsrichtung, so dass sie im geöffneten Zustand etwa rechtwinklig zur festen Greiferzunge 88 angeordnet ist. Die Schwenkachse 94, an welcher die bewegliche Greiferzunge 92 mit einem Ende befestigt ist, ist im Innern des Greifergehäuses 90 mit einem an diesem gelagerten Schliesshebel 98 verbunden. Auf diesem ist an dessen freiem Ende eine Steuerrolle 100 frei drehbar gelagert, die dazu bestimmt ist, zum Verbringen der beweglichen Greiferzunge 92 von der Offenstellung in die Schliessstellung, mit einer ortsfesten Schliesskulisse 102 zusammenzuwirken. Weiter ist im Greifergehäuse 90 ein Rastelement allgemein bekannter Art angeordnet, um die in Schliesstellung verbrachte Schwenkachse 94 zu verrasten. Diese Raste ist zum Freigeben der beweglichen Greiferzunge 92 ebenfalls in allgemein bekannter Art und Weise, beispielsweise mittels einer Öffnungskulisse, entriegelbar.On the boom 68 is seated on its facing away from the deflection drum 16 End of a gripper housing 90, on which a wave-shaped, spring-like, movable gripper tongue 92 around a running in the conveying direction F. Pivot axis 94 is mounted. One also on the gripper housing 90 attached, leaf spring-like designed hold-open spring 96 acts on the movable gripper tongue 92 in the opening direction, so that they in the open Condition arranged approximately at right angles to the fixed gripper tongue 88 is. The pivot axis 94 on which the movable gripper tongue 92 with one end is attached to the inside of the gripper housing 90 with a connected to this stored locking lever 98. On this is on the free end of a control roller 100 freely rotatably mounted for this purpose is intended for moving the movable gripper tongue 92 from the Open position in the closed position, with a fixed closing backdrop 102 cooperate. There is also a catch element in the gripper housing 90 generally known type arranged around the spent in the closed position Lock pivot axis 94. This catch is for releasing the movable one Gripper tongue 92 also in a generally known manner, for example unlockable by means of an opening backdrop.

Die Führungsschiene 72 definiert eine Bewegungsbahn für die Greifer 20, die von der Umlenktrommel 16 getrennt ist. In Förderrichtung F gesehen, verläuft die Bewegungsbahn in Richtung von oben gegen unten zur Umlenktrommel 16, dann um das Nockenrad 70 und die Antriebswelle 34 herum und etwa parallel zum stromabwärts der Umlenktrommel 16 verlaufenden Abschnitt der Bändchen 22 in Richtung von unten gegen oben. Die Führungsschiene 72 ist derart ausgebildet, dass die Umlaufbahn 104, entlang der sich die Greiferzungen 88 bewegen, sich im Bereich der Umlenkung der Schuppenformation S um die Umlenktrommel 16 von innen an die Schuppenformation S seitlich neben der Umlenktrommel 16 anlegt. Zu diesem Zweck steht die Schuppenformation S, wie dies aus der Fig. 2 ersichtlich ist, auf der dem Förderer 14 zugewandten Seite mit dem Randabschnitt 21 über die Umlenktrommel 16 vor. Dieser Randabschnitt 21 wird von den zwei an der Umlenktrommel 16 geradlinig vorbeiverlaufenden Bändchen 22 gestützt.The guide rail 72 defines a path of movement for the grippers 20, which is separated from the deflection drum 16. Seen in the direction of conveyance F, the trajectory runs in the direction from top to bottom towards the deflection drum 16, then around the cam gear 70 and the drive shaft 34 around and approximately parallel to the downstream of the deflection drum 16 Section of the tapes 22 in the direction from the bottom to the top. The Guide rail 72 is formed such that the orbit 104 is along which the gripper tongues 88 move in the area of the deflection the scale formation S around the deflection drum 16 from the inside to the Scale formation S is applied laterally next to the deflection drum 16. To this The purpose of this is the scale formation S, as can be seen from FIG. 2 is on the side facing the conveyor 14 with the edge portion 21 before the pulley 16. This edge section 21 will of the two running straight past the deflection drum 16 Ribbon 22 supported.

Die Umfangsgeschwindigkeit des Nockenrades 70 und somit die Geschwindigkeit der Tragkörper 76 und Greifer 20 ist derart gewählt, dass diese sich in einem geradlinig verlaufenden Abschnitt der Führungsschiene 72 wenigstens annähernd mit der Umlaufgeschwindigkeit des Transportbandes 10 und somit der Bändchen 22 bewegen. Im gezeigten Beispiel bewegen sich somit die Greifer 20 im Bereich der Umlenktrommel 16 mit grösserer Geschwindigkeit als die Schuppenformation S, hingegen sind diese beiden Geschwindigkeiten stromabwärts der Umlenktrommel 16 wenigstens annähernd identisch. Die Schliesskulisse 102 beginnt am stromabwärts gelegenen Ende des Umlenk- und Förderspalts 26 zu wirken. Auf jeden Fall sind die Greifer 20 geschlossen, bevor die von diesem zu erfassenden und zu haltenden Gegenstände 12 den Umlenk- und Förderspalt 26 verlassen haben.The peripheral speed of the cam wheel 70 and thus the speed the support body 76 and gripper 20 is selected such that they are at least in a rectilinear section of the guide rail 72 approximately at the rotational speed of the conveyor belt 10 and thus move the ribbon 22. In the example shown, move thus the grippers 20 in the region of the deflection drum 16 at a higher speed than the scale formation S, however, these are two speeds downstream of the deflection drum 16 at least approximately identical. The closing backdrop 102 begins at the downstream End of the deflection and conveying gap 26 to act. Definitely are the grippers 20 are closed before they can be gripped and closed holding objects 12 leave the deflection and conveying gap 26 to have.

Die in den Figuren gezeigte Einrichtung funktioniert wie folgt. Die in Schuppenformation S anfallenden Gegenstände 12, welche frei auf dem Transportband 10 aufliegen, gelangen mit ihrer dem Transportband 10 abgewandten, freiliegenden Flachseite 106 an der Umlenktrommel 16 zur Anlage und werden im Umlenk- und Förderspalt 26 in engstem Raum in Richtung gegen oben umgelenkt. Im Bereich dieser Umlenkung legen sich, in bestimmten Abständen, jeweils die festen Greiferzungen 88 der Greifer 20 auf der radial innenliegenden Flachseite im Randabschnitt 21 an die Schuppenformation S an. Beim oder kurz nach dem stromabwärts gelegenen Ende des Umlenk- und Förderspalts 26 wird der Greifer 20 durch Verschwenken der beweglichen Greiferzunge 92 in die Schliessstellung geschlossen, so dass er die Schuppenformation S im seitlichen Randabschnitt 21 ergreift und für den Weitertransport festhält.The device shown in the figures works as follows. In the Scale formation S resulting objects 12, which are free on the Conveyor belt 10 rest on it with the conveyor belt 10 facing, exposed flat side 106 on the guide drum 16 Plant and are in the deflection and conveying gap 26 in the smallest space in Directed towards the top. In the area of this deflection, at certain intervals, the fixed gripper tongues 88 of the grippers 20 on the radially inner flat side in the edge section 21 to the Scale formation S on. At or just after the downstream The end of the deflection and conveying gap 26 is the gripper 20 by pivoting the movable gripper tongue 92 is closed in the closed position, so that it has the scale formation S in the lateral edge section 21 grips and holds for further transport.

In bevorzugter Art und Weise ist der Abstand zwischen aufeinanderfolgenden Greifern 20 derart gewählt, dass er geringfügig kleiner ist als die in Förderrichtung gemessene Länge der zu transportierenden Gegenstände 12, so dass jeder Gegenstand 12 in der Schuppenformation S von wenigstens einem der Greifer 20 gehalten ist. In bevorzugter Weise wird durch die Wahl des Abstandes zwischen aufeinanderfolgenden Greifern 20 sichergestellt, dass keiner der Gegenstände 12 von drei oder mehr Greifern 20 gehalten ist. Dies ermöglicht den Transport der Schuppenformation S um Kurven, die in der Fläche der Schuppenformation S liegen.The distance between successive ones is preferred Grippers 20 selected such that it is slightly smaller than that in Direction of conveyance measured length of the objects to be transported 12, so that each object 12 in the scale formation S of at least one of the grippers 20 is held. Is preferably by the choice of the distance between successive grippers 20 is ensured, that none of the objects 12 of three or more grippers 20 is held. This enables the transport of the scale formation S around Curves that lie in the area of the scale formation S.

Die käfigartige Ausbildung der Umlenktrommel 16 ermöglicht, im Bereich der Umlenkung, zwischen den Stäben 30 ein wellenartiges Ausweichen der radial innenliegenden Teile der Gegenstände 12, bei Zeitungen oder Zeitschriften der radial innenliegenden Blätter. Diese Ausbildungsform gewährieistet bei kleinstem Raumbedarf eine schonende Umlenkung der Gegenstände 12. Dazu trägt weiter der Tendenzantrieb für die Umlenktrommel 16 bei. Es werden in Umfangsrichtung verlaufende Kräfte, die die Gegenstände beeinflussen könnten, wenigstens annähernd vermieden. Selbstverständlich kann die Umlenktrommel 16 auch mit einer geschlossenen Mantelfläche ausgebildet sein. Dies insbesondere, wenn dünne Gegenstände mit kleinerer gegenseitiger Überlappung zu transportieren sind.The cage-like design of the deflection drum 16 enables in the area the deflection, a wave-like evasion between the rods 30 radially inner parts of the objects 12, in newspapers or magazines of the radially inner leaves. This form of training guarantees with the smallest space requirement a gentle deflection of the objects 12. The tendency drive for the deflection drum also contributes to this 16 at. There are circumferential forces affecting the objects could influence, at least approximately avoided. Of course the deflection drum 16 can also have a closed outer surface be trained. This is especially true when thin objects are to be transported with a smaller mutual overlap.

Grundsätzlich ist es auch denkbar, die Greifer 20 derart anzutreiben, dass ihre Geschwindigkeit in einem geradlinigen Abschnitt der Führungsschiene 72 stromabwärts des Nockenrades 70 kleiner ist als die Geschwindigkeit der Bändchen 22 und der Umlenktrommel 16. Dies führt dazu, dass die von einem Greifer 20 festgehaltenen Gegenstände 12 zwischen diesem Greifer und dem stromabwärts gelegenen Ende des Umlenk- und Förderspalts 26 wellenartig gebogen werden, wobei die Wellenberge und Täler rechtwinklig zur Förderrichtung F verlaufen. Dies ermöglicht ein schonendes Transportieren der Gegenstände 12 um Kurven quer zur Fläche der Schuppenformation S.In principle, it is also conceivable to drive the grippers 20 in such a way that their speed in a straight line section of the guide rail 72 downstream of the cam wheel 70 is less than the speed of the ribbon 22 and the deflection drum 16. This leads to the objects 12 held by a gripper 20 between the latter Gripper and the downstream end of the deflection and conveyor gap 26 can be bent like a wave, with the crests and valleys run perpendicular to the conveying direction F. This enables gentle Transporting the objects 12 around curves across the surface of the Scale formation S.

Die Fördereinrichtung kann am Ende der Förderstrecke genau gleich ausgebildet sein, wie dies anhand der Fig. 1 und 2 am Anfang der Förderstrecke gezeigt ist. Einzig sind die Förderrichtung F und die Drehrichtung D umgekehrt und die Wegförderrichtung des Transportbandes 10 ist der Zuführrichtung Z entgegengesetzt. Weiter ist anstelle der Schliesskulisse 102 eine Öffnungskulisse für das Öffnen der Greifer 20 vorhanden.The conveyor can be of exactly the same design at the end of the conveyor line be like this with reference to FIGS. 1 and 2 at the beginning of the conveyor line is shown. Only the conveying direction F and the direction of rotation D are reversed and the conveying direction of the conveyor belt 10 is the feeding direction Z opposite. Next is the closing backdrop 102 an opening backdrop for opening the gripper 20 available.

Selbstverständlich ist es auch denkbar, den Förderer 14 unterschiedlich auszubilden. Dazu sind infolge dessen Unabhängigkeit von der Umlenktrommel 16 die verschiedensten Möglichkeiten geboten.Of course, it is also conceivable to differentiate the conveyor 14 train. As a result, this means independence from the deflection drum 16 offered a wide variety of options.

Der Umlenk- und Förderspalt verläuft im gezeigten Beispiel um zirka 90° um die Umlenktrommel 16. Dieser Umschlingungswinkel kann grösser oder kleiner gewählt werden. Dies ermöglicht eine einfache Anpassung an räumliche Gegebenheiten.The deflection and conveying gap runs in the example shown by approximately 90 ° around the pulley 16. This wrap angle can be larger or be chosen smaller. This enables easy adaptation to spatial conditions.

Die Umlenktrommel 16 kann auf der Antriebswelle 34 frei drehbar gelagert sein.The deflection drum 16 can be freely rotatably supported on the drive shaft 34 his.
