The stop portions are pulled back down and the crate is pushed through the rollers (3) in the direction of the stacking station (C). The rotation of conveyor rollers (3r) is independent from the movements of the feeding conveyor (1a) and by controlling the movement of the conveyor belts (5e,5f).

Description

Es sind Sortiermaschinen für Steigen aus Kunststoff mit klappbaren Seitenwänden bekannt welche, an den vereinzelt zugeführten Steigen, mechanische und/oder optische Erhebungen durchführen um, anhand einiger Merkmale betreffend die Konstruktion und/oder die Maße, das jeweilige Modell der Steigen und auch eventuelle schadhafte Steigen feststellen können um sie den jeweiligen Stapelstationen, bzw. einer gemeinsamen Ausschussstation zuzuführen.There are sorting machines for plastic crates with hinged side walls known which perform at the occasionally supplied crates, mechanical and / or optical surveys to, based on some features relating to the construction and / or dimensions, the respective model of the crates and any defective trays can determine to supply them to the respective stacking stations, or a common reject station.

Nachdem an den bekannten Sortiermaschinen die mechanischen Erhebungen an den Steigen, während deren Weiterförderung, bzw. während deren Halt, erfolgen und die Steigen dabei jedoch öfters leicht unterschiedliche Positionen zur exakt vorgegebenen Messposition einnehmen, kommt es zu verschiedenen Messfehlern welche Sortier- und Stapelfehler und öfters auch Verklemmungen verursachen. Die optische Erhebung hingegen bewirkt oft, dass die nur leicht verzogenen Seitenwände oder Böden einer Steige, deren Ausschuss bewirkt, auch wenn diese Steige effektiv noch vollkommen funktionstüchtig wäre. Die bekannten Maschinen haben dadurch, dass die Stapelung nach einzelnen Modellen durch von unten wirkenden Kolben erfolgt, beachtenswerte Ausmaße, weiters sind für die Stapelung der kleinen Steigen (300 x 400) spezifische Stapelschächte vorgesehen welche öfters nicht genutzt werden. Die Arbeitsgeschwindigkeit der bekannten Sortiermaschinen ist öfters nicht ausreichend hoch weswegen, in einer komplexen Bearbeitungsanlage, wie z.B. einer Steigen-Waschanlage, die begrenzte Arbeitsgeschwindigkeit der Sortiermaschine, die Leistungsfähigkeit der gesamten Anlage beeinflusst.After the mechanical surveys on the crates, during their further promotion, or during their hold, made on the known sorting machines and the crates but often take slightly different positions for exactly predetermined measurement position, it comes to different measurement errors which sorting and stacking faults and more often also cause jamming. The optical survey, however, often causes the only slightly warped sidewalls or bottoms of a crate, which causes waste, even if this crate was effectively still fully functional. The known machines have the fact that the stacking is done by individual models by acting from below piston, noteworthy proportions, further provided for the stacking of small crates (300 x 400) specific stacking shafts which are often not used. The operating speed of the known sorting machines is often not sufficiently high, therefore, in a complex processing plant, such as e.g. a climbing car wash, the limited working speed of the sorting machine, which affects the performance of the entire system.

Die Erfindung stellt sich die Aufgabe eine Sortiermaschine für Steigen mit klappbaren Seitenwänden der eingangs beschriebenen Art zu schaffen um dabei das Erhebungssystem und die Arbeitsgeschwindigkeit zu verbessern, die Gesamtausmaße der Maschine zu reduzieren und die Möglichkeit zu schaffen, dass jeder der Stapelschächte für große Steigen (600 x 400), in eine Stapelschacht für kleine Steigen (300 x 400) umfunktioniert werden kann.The invention has as its object to create a sorting machine for climbing with hinged side walls of the type described above to thereby to improve the survey system and speed of operation, to reduce the overall dimensions of the machine and to make it possible for each of the stacking shafts to be converted for large trays (600 x 400) into a stack tray for small trays (300 x 400).

Zur Lösung dieser Aufgabe schlägt die Erfindung vor, dass die Erhebung des Steigenmodells, bzw. von Schäden an den einzeln der Sortiermaschine zugeführten Steigen, ausschließlich mechanisch bei stillstehender Steige welche eine absolut definierte Position einnimmt, erfolgt, auch wenn das Zuführen in diese definierte Erhebungsposition und auch der folgende Transport zur Stapelstation, bzw. zur Ausschussstation, unter hoher Geschwindigkeit erfolgt. Weiters schlägt die Erfindung vor, dass jede der Stapelstationen durch hohe Zuführgeschwindigkeiten der einzelnen Steigen gespeist wird und zwar unabhängig von den Änderungen der Geschwindigkeit welche die Steige während der Zuführung zu, und während der Abführung von, der Erhebungsstation erfährt und unabhängig vom, auch nur sehr kurzen, Halt der Steige während der Erhebungsphase.To solve this problem, the invention proposes that the survey of the riser model, or damage to the individual of the sorting machine supplied cramps, exclusively mechanically in stationary crates which occupies an absolutely defined position, even if the feeding in this defined survey position and also the following transport to the stacking station, or to the reject station, takes place at high speed. Furthermore, the invention proposes that each of the stacking stations be fed by high feed rates of the individual trays, regardless of the changes in speed which the tray experiences during feeding to, and during discharge from, the rump station, and even very little short, hold the crate during the survey phase.

Erfindungsgemäß wird die Steige welche auf einem Transportband der Erhebungsstation zugeführt wird, mindestens einseitig, von seitlichen Rollen mit vertikaler Drehachse erfasst welche seitlich an den Seitenrändern der Steige greifen um sie gegen zwei mechanische, nach einer Linie quer zur Vorwärtsbewegung der Steige angeordneten Anschlägen, zu schieben. Diese besagten Anschläge sind durch, an der horizontalen Auflageplatte für die Steige vorgesehene, Öffnungen hindurch senkrecht beweglich, diese Anschläge nehmen die ausgefahrene vorstehende aktive Position ein sobald sich eine Steige nähert und werden in die zurückgezogene Position eingezogen sobald die Erhebung an der Steige erfolgt ist.
Nach einem kurzen Halt der Steige welche mit dem vorderen Rand an den vertikal beweglichen Anschlägen anliegt und während welchem die mechanische bekannte Erhebung mittels elastisch an die darunter liegende Steige angedrückter Taster erfolgt und infolge Rückziehen der genannten Anschläge, schieben die seitlichen Förderrollen in Richtung der seitlichen Förderriemen oder der seitlichen Förder-Rollengruppen welche an beiden Längsseiten einer Reihe von zueinander, gemäß Förderrichtung der Steigen ausgerichteter Stapelschächte, vorgesehen sind.According to the invention, the crate, which is supplied on a conveyor belt of the survey station, at least on one side of lateral rollers with vertical axis of rotation detects which laterally grip on the side edges of the crate to push against two mechanical, arranged according to a line transverse to the forward movement of the crate attacks , These said stops are vertically movable through apertures provided on the horizontal platen for the crates, these stops take the extended projected active position as soon as a crate approaches and are retracted to the retracted position once the crest on the crate has been made.
After a short stop of the crate which rests with the front edge of the vertically movable stops and during which the mechanical known survey is carried out by means of elastically pressed against the underlying crate button and as a result of retracting said attacks, push the lateral conveyor rollers in the direction of the lateral conveyor belt or the lateral conveyor roller groups which are provided on both longitudinal sides of a series of mutually aligned according to the conveying direction of the crates stacking shafts.

Erfindungsgemäß beschleunigen mindestens zwei Förderrollen die Bewegung der Steige nachdem sie vom Zuführ-Förderband abgenommen worden ist um sie, innerhalb kürzester Zeit, mit dem vorderen Rand in eine Position nahe den zwei von der Auflageplatte vorstehenden Anschlägen zu bringen. Anschließend an der Einnahme der besagten Position nahe der Anschläge, wird die Bewegung der Steige verlangsamt bis der besagte vordere Rand an den Anschlägen anliegt. Infolge des Kontaktes des vorderen Randes an beiden Anschlägen wird die Steige in dieser anliegenden Position dadurch gehalten, dass die Rollen sie mit einem bestimmten Drehmoment gegen die Anschläge schieben. Dieser erfindungsgemäße Ablauf sichert die exakte Positionierung und die bewegungslose Halterung der Steige für die Durchführung der effizienten und genauen Erhebungen an der zugeführten Steige, welche in jenem Moment erfolgt an welchem die Rollen die Steige gegen die Anschläge drücken. Diese Erhebung wird durch eine Reihe bekannter Taster durchgeführt welche elastisch gegen die obere Fläche der darunter liegenden Steige mit zugeklappten Seitenwänden gedrückt werden.According to the invention, at least two conveyor rollers accelerate the movement of the tray after it has been removed from the feed conveyor belt to bring it, within a very short time, with the front edge in a position close to the two protruding from the support plate attacks. Subsequent to taking the said position near the stops, the movement of the tray is slowed down until said front edge abuts against the stops. Due to the contact of the front edge of both attacks the crate is held in this adjacent position in that the rollers push them with a certain torque against the stops. This process according to the invention ensures the exact positioning and the motionless support of the crate for the implementation of the efficient and accurate surveys on the supplied crate, which occurs at the moment at which the rollers press the crate against the stops. This survey is carried out by a series of known buttons which are pressed elastically against the upper surface of the underlying crate with folded side walls.

Sobald die Erhebung durchgeführt ist und die Anschläge in die zurückgezogene Stellung gefahren sind, wird die Steige durch die selben Rollen in Richtung der, seitlich der Reihe von Stapelschächten vorgesehenen, Förderriemen geschoben. Während der besagten Weiterförderung beschleunigen die Rollen die Bewegung der Steige von 0 m/sec. auf eine Geschwindigkeit welche gleich jener der Förderriemen für die folgende Weiterförderung der Steige in Richtung zu den Stapelschächten ist.Once the survey has been completed and the stops have been moved to the retracted position, the tray is pushed by the same rollers in the direction of, provided at the side of the row of stacking shafts, conveyor belt. During said advancement, the rollers accelerate the movement of the crate from 0 m / sec. to a speed equal to that of the conveyor belts for the subsequent advancement of the tray towards the stacking shafts.

Erfindungsgemäß können die besagten seitlichen Rollen durch mindestens ein Förderband pro Seite ersetzt werden, wodurch eine größere Anlagefläche am Seitenrand der Steige erreicht wird.According to the invention, the said lateral rollers can be replaced by at least one conveyor belt per side, whereby a larger contact surface is reached at the side edge of the crate.

Erfindungsgemäß können die Förderbänder für die Steigen welche längs der hintereinander fluchtend angeordneten Stapelschächte vorgesehen sind, nur zwei sein, eine an jeder der Längsseiten der Stapelschächte, oder es können spezifische Bänderpaare für jede der Stapelschächte vorgesehen sein, welche so angeordnet sind, dass die Steige von einem Riemenpaar zum folgenden befördert wird. Während der Weiterförderung der Steigen mittels der besagten Riemen, liegen diese nicht auf einer unteren Führung oder Auflage auf. Die besagten Riemen werden durch Rollengruppen seitlich gegen die sich gegenüberliegenden Ränder der Steigen gedrückt, diese Stützrollen sind an Profilstangen gelagert welche ihrerseits in Richtung Steigenrand beweglich sind und durch Pneumatikzylinder welche an den Endbereichen jeder Profilstange wirken, schwenkbar sind. Insbesondere die Schwenkbewegung ermöglicht eine beachtenswerte Anpassung der Förderriemen während des Durchlaufes der Steigen welche Abmaße mit eher weiten Maßtolleranzen haben. Natürlich können die Trägerrollen durch Trägerplatten ersetzt werden an denen die Rückseite der Förderriemen läuft. Sobald die Steige, infolge der durchgeführten Erhebungen, den spezifischen Stapelschacht erreicht, werden die Förderriemen blockiert und die betreffenden Profilstangen mit den Trägerrollen sowie die Förderriemen selbst werden zurückgezogen, wobei sie im Abschnitt entsprechend dem Schacht der besagten Stapelstation, vom Seitenrand der Steige entfernt werden, so dass die Steige frei nach unten in den besagten Stapelschacht fallen kann, wo die Steigen auf bekannte Art in einer ersten Phase im oberen Bereich des Stapelschachtes welcher als Puffer fungiert, gestapelt werden, um anschließend in den unteren Stapelbereich zu gelangen wo eine, durch Zahnriemen vertikal betätigte, Auflage nach unten, in Abhängigkeit der vom oberen Puffer-Bereich periodisch entnommenen Steigengruppe, bewegt wird um dadurch nicht die Stapelung während der Entnahme eines Steigenstapels zu unterbrechen. Jeder der Stapelschächte kann erfindungsgemäß im Bereich des freien Falls der Steigen, im mittleren Bereich, mit einem querverlaufenden Trennschied ausgestattet sein um diesen Schacht für die Stapelung kleiner Steigen (300 x 400) des selben Modells auszurüsten, welche abwechselnd an einer Seite und an der gegenüberliegenden Seite des Trennschiedes abgelegt werden. Um Hemmungen zu verhindern, sieht die Erfindung vor, dass der Fall der kleinen Steigen immer so erfolgt dass ihr, zur Förderrichtung, quer liegender Rand auf ein Einleitblech fällt welches an jedem der kurzen Seiten jedes der Stapelschächte vorgesehen ist und nicht in einer am Trennschied anliegenden Position fällt.According to the invention, the conveyor belts for the trays provided along the successively aligned stacking shafts may be only two, one on each of the longitudinal sides of the stacking shafts, or specific pairs of belts may be provided for each of the stacking trays arranged so that the trays of one belt pair is transported to the next. During the further promotion of the crates by means of said belt, they do not rest on a lower guide or support. The said belts are pressed by roller groups laterally against the opposite edges of the crates, these support rollers are mounted on profile rods which in turn are movable in the direction of the rim and by pneumatic cylinders which act on the end portions of each profile bar, are pivotable. In particular, the pivoting movement allows a remarkable adjustment of the conveyor belt during the passage of the crates which have dimensions with rather wide Maßollerolleranzen. Of course, the carrier rolls can be replaced by carrier plates on which the back of the conveyor belt runs. As soon as the crate reaches the specific stacking shaft due to the surveys made, the conveyor belts are blocked and the respective profiled bars with the carrier rolls and the conveyor belts themselves are withdrawn, being removed from the side edge of the crate in the section corresponding to the shaft of said stacking station. so that the tray can fall freely down into said stacking tray where the trays are stacked in a known manner in a first phase at the top of the stacking tray which serves as a buffer to subsequently enter the lower stacking tray where there is a toothed belt vertically operated, pad down, depending on the periodically removed from the upper buffer area tray group is moved to thereby not interrupt the stacking during the removal of a stack of riser. Each of the stack shafts can according to the invention in the field of free fall of the crates, im middle section, with a transverse divider to equip this shaft for the stacking of small trays (300 x 400) of the same model, which are placed alternately on one side and on the opposite side of the separation. In order to prevent inhibitions, the invention provides that the case of the small crates always takes place so that their, transverse to the conveying direction transverse edge falls on a guide plate which is provided on each of the short sides of each of the stacking shafts and not in a voltage applied to the separation Position falls.

Natürlich kann das Rückziehen der Rollengruppen zusammen mit dem Förderriemen im Bereich eines jeden der Stapelschächte, durch lineares horizontales Verstellen oder durch Schwenken um eine, zur Förderrichtung der Steigen, parallelen Achse erfolgen. Im Falle eines Stapelschachts mit Trennschied zwecks Stapelung kleiner Steigen, werden die Rollengruppen und die Förderbänder immer über die gesamte Längserstreckung des Stapelschachts zurückgezogen, nachdem für diesen Bereich immer nur eine der kleinen Steigen zwischen den Förderbändern gehalten wird.Of course, the retraction of the roller groups together with the conveyor belt in the region of each of the stacking shafts, by linear horizontal adjustment or by pivoting about a, to the conveying direction of the crates, parallel axis. In the case of a stacking shaft with separation difference for stacking small crates, the roller groups and the conveyor belts are always withdrawn over the entire longitudinal extent of the stacking shaft, since only one of the small crates is held between the conveyor belts for this area.

Erfindungsgemäß können die Förderriemen für die Steigen, in Richtung der Stapelschächte, längs dem unteren Rand, in Richtung zu den Steigen, einen vorspringenden Längsrand, mehrere nach oben geneigte, elastisch verformbare Längslappen oder geneigte vertikale Lappen aufweisen um zu erreichen, dass verzogene oder schadhafte Steigen korrekt gehalten werden, ohne dass ein Steigenteil nach unten, über den unteren Rand der besagten Förderbänder, absteht und dabei Förderhemmungen oder Förderstörungen verursacht. Natürlich können die besagten vorstehenden Lappen auch durch Noppen ersetzt werden welche durch ihre elastische Verformung die Auflagefläche für die Ränder der festgehaltenen Steige erhöhen.
Die aussortierten Steigen werden auf bekannte Art, in einem Bereich jenseits der verschiedenen Stapelschächte ausgeworfen wo sie von einem eigenen Behälter aufgenommen werden.According to the invention, the conveyor belts for the crates, in the direction of the stack shafts, along the lower edge, towards the crates, may have a projecting longitudinal edge, a plurality of upwardly inclined, elastically deformable longitudinal flaps or inclined vertical flaps to achieve warped or damaged crumbs be held correctly without a part of the riser down, over the lower edge of said conveyor belts, protruding, thereby causing conveyor inhibitions or conveyor faults. Of course, the said projecting lobes can also be replaced by nubs which increase the contact surface for the edges of the captured crate by their elastic deformation.
The sorted crates are ejected in a known manner, in an area beyond the various stack shafts where they are taken from a separate container.

Die verschiedenen Modelle der Steigen A mit den zugeklappten Seitenwänden werden durch ein Förderband 1 der Erhebungsstation B zugeführt 1a, diese besteht wesentlich aus einer unteren Auflageplatte 3x mit zwei vertikal verstellbaren Anschlägen 4, aus einer Reihe von Tastern 2 welche elastisch von oben gegen die darunter liegende Steige A gedrückt werden und aus mindestens einer rotierenden 3r Förderrolle 3 pro Seite, welche um eine vertikale Achse schwenkbar gelagert ist und durch Zylinder 3a gegen die Seitenränder der Steige A gedrückt wird. Die Erfindung schließt nicht aus, dass die besagten seitlichen Rollen 3 durch Förderriemen ersetzt werden. Sobald der vordere Teil der beiden seitlichen Ränder der mittels Förderband 1 zugeführten 1a Steige A, mit den Förderrollen 3 in Berührung kommen, beschleunigen diese die Förderbewegung bis der vordere Rand der Steige A sich in einer Position nahe an den beiden, sich in ausgefahrener aktiver Position befindenden, Anschlägen 4 befindet. Anschließend fördern die Rollen 3 die Steige A mit reduzierter Geschwindigkeit gegen die besagten Anschläge 4 und schieben diese andauernd mit einer bestimmten Kraft gegen die besagten Anschläge 4 um dadurch die exakte Position und den absoluten Stillstand der Steige zu erreichen. Während dieser Position des absoluten Stillstandes wird auf bekannte Art die Erhebung, z.B. mittels einer Reihe von Taster 2, durchgeführt um das Modell und um eventuelle Verformungen der Steige zu erkennen. Nach der Erhebung werden die Anschläge 4 nach unten zurückgezogen und die Steige A wird durch die Rollen 3 in Richtung der Stapelstationen C geschoben, wobei die Geschwindigkeit von 0 m/sec. auf eine Geschwindigkeit gleich jener der, an beiden Seiten der Reihe der unter sich ausgerichteten Stapelschächte 5a, 5b vorgesehenen, Förderriemen 5e beschleunigt wird. Die Rotation 3r der besagten Förderrollen 3 ist also unabhängig von den Bewegungen 1a des Zuführ-Förderbandes 1 und von den Bewegungen 5f der Förderriemen 5e gesteuert.The different models of the trays A with the folded side walls are fed by a conveyor belt 1 of the survey station B 1a, this consists essentially of a lower support plate 3x with two vertically adjustable stops 4, from a series of buttons 2 which elastically from above against the underlying Riser A are pressed and at least one rotating 3r conveyor roller 3 per side, which is pivotally mounted about a vertical axis and is pressed by cylinder 3a against the side edges of the tray A. The invention does not exclude that said side rollers 3 are replaced by conveyor belts. As soon as the front part of the two lateral edges of the conveyor A 1 supplied by conveyor belt 1, come into contact with the conveyor rollers 3, these accelerate the conveying movement until the front edge of the tray A in a position close to the two, in the extended active position located, stops 4 is located. Subsequently, the rollers 3 convey the tray A at a reduced speed against the said stops 4 and push them constantly with a certain force against the said stops 4 in order thereby to reach the exact position and the absolute standstill of the tray. During this position of absolute standstill, the survey is carried out in a known manner, for example by means of a series of push-buttons 2, in order to detect the model and possible deformations of the tracks. After the survey, the stops 4 are pulled back down and the tray A is pushed by the rollers 3 in the direction of the stacking stations C, the speed of 0 m / sec. to a speed equal to that of the conveyor belt 5e provided on both sides of the row of the stacked stackers 5a, 5b. The rotation 3r of said conveyor rollers 3 is thus controlled independently of the movements 1a of the feed conveyor belt 1 and by the movements 5f of the conveyor belts 5e.

Die besagten Förderriemen 5e sind durch treibende Riemenscheiben 5g angetrieben und können allein für die gesamte Anordnung der Stapelschächte 5a, 5b vorgesehen sein. Die Steigen A werden, ohne untere Gleitauflage, zwischen den besagten Riemen 5e dadurch gehalten, dass diese gegen die sich gegenüberliegenden Ränder der dazwischen liegenden Steige A durch Pneumatikzylinder 5i gedrückt werden welche auf die horizontal und quer zur Förderbewegung 5f der Riemen 5e, beweglichen 5n Profilstangen 5p wirken. Die Profilstangen 5p können weiters eine Schwenkbewegung 5x ausführen welche beim Durchlauf von Steigen mit leicht unterschiedlicher Breite eine Angleichung ermöglicht um immer eine sichere Weiterförderung der Steige zu garantieren. Die besagten Profilstangen 5p, welche sich ungefähr über die gesamte Längserstreckung jeder der einzelnen Stapelschächte 5a erstrecken, sind mit einer Reihe von Stützrollen 5h ausgestattet an welchen der Riemen 5e aufliegt und mit Rückziehelementen 5m ausgestattet welche an beiden Längsrändern des Riemens 5e wirken um zu erreichen, dass die Steige A frei in jenen Stapelschacht 5a fallen kann welcher in der Erhebungsphase zur Bestimmung des Steigenmodells bestimmt worden ist. Die besagten Rückziehelemente 5m wirken auf die Riemen 5e infolge der Positionierung der Steige A genau über dem entsprechenden Stapelschacht 5a, 5b und infolge des Anhaltens der Riemen in dieser Position. Auch in Präsenz eines vertikal eingesetzten Trennschiedes 5c um in einem der Stapelschächte für große Steigen, zwei Stapelschächte 5b für kleine Steigen zu erhalten, erstrecken sich die beiden Profilstangen 5p um den Riemen 5e die Druckbewegung 5n gegen die Ränder der dazwischen liegenden Steige A zu übertragen, bzw. um das Rückziehen zu erreichen damit die Steige in den entsprechenden Stapelschacht fällt, über die gesamte Länge des Stapelschachtes ohne Trennschied 5c.The said conveyor belts 5e are driven by driving pulleys 5g and may be provided solely for the entire arrangement of the stacking shafts 5a, 5b. The trays A are, without a lower sliding support, held between the said belts 5e by being pressed against the opposite edges of the intermediate trays A by pneumatic cylinders 5i which are movable horizontally and transversely to the conveying motion 5f of the belts 5e 5p act. The profile rods 5p can further perform a pivoting movement 5x which allows for the passage of crates with slightly different widths an approximation to always guarantee a safe further promotion of the crate. Said profiled bars 5p, which extend approximately over the entire longitudinal extent of each of the individual stacking shafts 5a, are provided with a series of supporting rollers 5h on which the belt 5e rests and equipped with retraction elements 5m which act on both longitudinal edges of the belt 5e to reach that the crate A can fall freely into those stacking shaft 5a which has been determined in the survey phase for the determination of the crate model. The said retracting members 5m act on the belts 5e due to the positioning of the tray A just above the corresponding stacking tray 5a, 5b and due to the stopping of the belts in this position. Even in the presence of a vertically inserted separation difference 5c in order to obtain two stacking shafts 5b for small crates in one of the stacking shafts, the two profiled bars 5p extend around the belt 5e to transmit the pressing movement 5n against the edges of the crates A therebetween. or to reach the retraction so that the crate falls into the corresponding stacking shaft, over the entire length of the stacking shaft without a separation 5c.

Die Erfindung schließt nicht aus, dass die besagten zwei Förderriemen 5e durch einzelne Riemenpaare ersetzt werden welche an Profilstangen 5p mit Stützrollen 5h laufen, wobei diese Profilstangen beweglich 5n oder um Längsachsen, parallel zur Förderrichtung der Steige A schwenkbar, gelagert sind. In diesem Fall können die Profilstangen 5p frei von Rückziehelementen 5m sein. Weiters können natürlich die Stützrollen 5h durch Gleitplatten ersetzt werden. Jede der Stapelschächte 5a ist an den Seiten, quer zur Förderrichtung der Steigen A, mit Leitblechen 5d versehen. Im Falle dass kleine Steigen in den durch ein Trennschied 5c definierten Schächten 5b gestapelt werden, so werden diese abwechselnd in die beiden anliegenden Räumen des Stapelschachtes 5b abgelegt und zwar immer mit dem Rand welcher der Position des besagten Leitbleches 5d entspricht nahe diesem und mit dem entgegengesetzten Rand distanziert vom Trennschied 5c.The invention does not exclude that the said two conveyor belts 5e are replaced by individual pairs of belts which run on profile bars 5p with support rollers 5h, said profile bars are movably 5n or about longitudinal axes, parallel to the conveying direction of the tray A, stored. In this case, the profile bars 5p may be free of retraction elements 5m. Furthermore you can Of course, the support rollers 5h are replaced by sliding plates. Each of the stacking shafts 5a is provided on the sides, transversely to the conveying direction of the trays A, with baffles 5d. In the case that small crates are stacked in the shafts 5b defined by a separating difference 5c, they are alternately deposited in the two adjoining spaces of the stacking shaft 5b, always with the edge corresponding to the position of said guide plate 5d close to it and with the opposite one Rand distanced from the separation difference 5c.

Die Stapelung der Steigen innerhalb des Schachtes 5a, 5b erfolgt auf bekannte Weise indem ein Vorstapeln im oberen Bereich des Schachtes erfolgt, diese Stapelung hat während der Zeit der Entnahme der gestapelten Steigen aus dem Stapelschacht eine Pufferfunktion. An Stelle der, während der Stapelung auf bekannte Weise durch einen Zylinder bewegte, Auflage für den Stapel der Steigen, schlägt die Erfindung einen Antrieb durch Elektromotor mit Zahnriemen vor, wodurch eine Verminderung der Bauhöhe der Maschine möglich wird.The stacking of the crates within the shaft 5a, 5b is carried out in a known manner by pre-stacking in the upper region of the shaft, this stacking has a buffer function during the time of removal of the stacked crates from the stacking shaft. Instead of, during the stacking in a known manner by a cylinder moving support for the stack of trays, the invention proposes a drive by electric motor with toothed belt, whereby a reduction in the height of the machine is possible.
