Description

Die vorliegende Erfindung betrifft eine Einrichtung nach dem Oberbegriff des Patentanspruches 1.The present invention relates to a device according to the preamble of patent claim 1.

In der CH-PS 637 091 (weitgehend inhaltsgleich mit der EP-PS 0 013 920 und der US-PS 4 333 559) ist angegeben, wie und weshalb ein Schuppenstrom erzeugt wird, in dem die Druckereierzeugnisse paarweise deckungsgleich aufeinanderliegen. Der wohl wichtigste Grund, einen solchen Schuppenstrom zu bilden, ist darin zu erblicken, dass, namentlich bei dünneren Druckereierzeugnissen, die Geschwindigkeit der an die Druckerpresse anschliessenden und die Druckereierzeugnisse wegführenden Fördereinrichtung bei gleichem Durchsatz pro Zeiteinheit auf etwa die Hälfte reduziert werden kann.CH-PS 637 091 (largely identical in content to EP-PS 0 013 920 and US-PS 4 333 559) specifies how and why a shingled stream is generated in which the printed products lie congruently in pairs. The most important reason for forming such a shingled stream is to be seen in the fact that, particularly with thinner printed products, the speed of the conveying device connected to the printing press and leading away from the printed products can be reduced to about half with the same throughput per unit of time.

Sollen dann aus einem solchen Schuppenstrom Stapel oder Pakete gebildet werden, dann bringt es die Doppelbelegung jedes "Platzes" im Schuppenstrom mit sich, dass ein gebildeter Stapel oder gebildetes Paket stets nur eine gerade Anzahl von Druckereierzeugnissen enthält.If stacks or packets are then to be formed from such a shingled stream, the double occupancy of each “place” in the shingled stream means that a stack or formed bundle always contains only an even number of printed products.

Ein einziges überzähliges Druckereierzeugnis in einem Stapel, der an sich eine ungerade Anzahl Druckereierzeugnisse enthalten sollte, wäre zwar tolerierbar. Bedenkt man aber eine gesamte Auflage von Druckereierzeugnissen (in der Regel weit über 100'000), dann addieren sich solche überzähligen Erzeugnisse je Stapel oder Paket zu einer ansehnlichen Menge.A single surplus printed product in a stack, which should contain an odd number of printed products per se, would be tolerable. However, if you consider an entire edition of printed products (generally well over 100,000), then such excess products add up to a considerable amount per stack or package Amount.

Hier setzt die Erfindung ein, deren Aufgabe es ist, eine Einrichtung der eingangs genannten Art derart auszubilden, dass es auch mit einem "doppel belegten" Schuppenstrom gelingt, Stapel mit einer ungeraden Anzahl Druckereierzeugnisse herzustellen.This is where the invention comes in, the task of which is to design a device of the type mentioned at the beginning in such a way that even with a "double-occupied" stream of shingles it is possible to produce stacks with an odd number of printed products.

Diese Aufgabe löst die vorgeschlagene Einrichtung dadurch, dass sie die im Kennzeichen des Patentanspruches 1 umschriebenen Merkmale aufweist.This object is achieved by the proposed device in that it has the features described in the characterizing part of patent claim 1.

Merkmale bevorzugter Ausführungsformen sind in den abhängigen Ansprüchen umschrieben.Features of preferred embodiments are described in the dependent claims.

Die Erfindung ist nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben. Es zeigt:

Fig. 1
eine schematische Draufsicht auf eine Stapeleinrichtung; und
Fig. 2
in grösserem Massstab eine vereinfachte Ansicht der Einrichtung der Fig. 1, etwa aus der Richtung des Pfeiles II der Fig. 1.
The invention is described below with reference to an embodiment shown in the drawing. It shows:
Fig. 1
a schematic plan view of a stacking device; and
Fig. 2
on a larger scale a simplified view of the device of FIG. 1, approximately from the direction of arrow II of FIG. 1st

Bei der in Fig. 1 und 2 dargestellten Einrichtung 10 erkennt man einen Bändchenförderer 11, der in Richtung des Pfeiles 12 Druckereierzeugnisse 13 in einer geschuppten Formation, in der eine Ecke der Druckereierzeugnisse 13 vorausläuft, heranführt. An den Bändchenförderer 11 schliesst ein weiterer Bändchenförderer 14 an, der sowohl untere Bändchen 15 (Fig. 2) als auch obere Bändchen 16 aufweist, zwischen denen die Druckereierzeugnisse 13 paarweise deckungsgleich aufeinanderliegend eingeklemmt sind und einem von oben beschickbaren Stapelschacht 17 zugeführt werden.In the device 10 shown in FIGS. 1 and 2, a ribbon conveyor 11 can be seen which, in the direction of the arrow 12, brings printed products 13 in a shingled formation in which a corner of the printed products 13 runs ahead. Another ribbon conveyor 14 connects to the ribbon conveyor 11, both has lower ribbons 15 (FIG. 2) and upper ribbons 16, between which the printed products 13 are clamped in congruent pairs and are fed to a stacking shaft 17 which can be loaded from above.

Der Stapelschacht 17 ist seitlich durch eine Anschlagplatte 18 und durch Anschlagschienen 19 begrenzt, die beide horizontal verstellbar und feststellbar sind, um die lichten Masse des Stapelschachtes 17 dem Format der anfallenden Druckereierzeugnisse anzupassen.The stacking shaft 17 is laterally delimited by a stop plate 18 and by stop rails 19, both of which are horizontally adjustable and lockable, in order to adapt the clear mass of the stacking shaft 17 to the format of the printed products.

Bei der vorliegenden Einrichtung fallen die paarweise dem Stapelschacht zugeführten Druckereierzeugnisse 13, wie der Fig. 2 zu entnehmen ist, entweder auf einen den Boden des Stapelschachtes bildenden Stapeltisch (nicht dargestellt), oder - beispielsweise in der Zeit, da ein Stapel vom Stapeltisch zu entfernen ist - auf eine Traggabel 20 (Fig. 1), deren Zinken durch die Anschlagschienen 19 durchsetzende Kolbenstangen 21 von Kolben-Zylinderaggregaten 22 gebildet sind, die ihrerseits an einem gemeinsamen Träger 23 befestigt sind, der längs der Anschlagschienen 19 auf und ab verschiebbar ist. Anschliessend an den Auslauf des Bändchenförderers 14 ist eine Halteeinrichtung 24 vorgesehen. Die Halteeinrichtung 24 besitzt einen Pneumatikzylinder 25, dessen rohrförmige Kolbenstange 26 beiderends aus dem Zylinder 25 herausgeführt ist. Am unteren Ende trägt die Kolbenstange 26 einen balgförmigen Saugnapf 27, dem durch die Kolbenstange 26 hindurch Unterdruck von einer am oberen Ende der Kolbenstange 26 montierten Saugpumpe 28 zugeführt wird. Die Saugpumpe 28 ist mit Druckluft betrieben. Das obere Ende des Zylinders 25 ist an einem Bügel 29 befestigt, der seinerseits um einen Zapfen 30 in der Vertikalebene schwenkbar an einem Rahmenteil 31 der Einrichtung aufgehängt ist. Vom Rahmenteil 31 geht ein Ausleger 32 aus, an dem das eine Ende einer Zugfeder 33 eingehängt ist. Das andere Ende der Zugfeder 33 ist an einer am oberen Ende der Kolbenstange 26 befestigten Lasche 34 eingehängt. Mit der strichpunktierten Linie 35 ist die Richtung der Zugfeder 33 in der in Fig. 2 mit ausgezogenen Linien gezeigten Stellung der Halteeinrichtung 24 angedeutet. Man sieht, dass in dieser Stellung die Richtung der Zugfeder 33 oberhalb des Zapfens 30 verläuft, so dass diese Feder 33 die Tendenz hat, die Halteeinrichtung 24 in der mit ausgezogenen Linien dargestellten Stellung zu halten. Sobald aber die Kolbenstange 26 nach unten ausgefahren wird, wirkt die Zugfeder 33 in entgegengesetztem Sinne. Am Rahmenteil 31 ist auch ein Puffer 36 befestigt, der ein hartes Aufschlagen des Bügels 29 am Rahmenteil 31 bei der Rückkehr des Zylinders 25 von der verschwenkten in die unverschwenkte Stellung verhindert.In the present device, the printed products 13 supplied in pairs to the stacking chute, as can be seen in FIG. 2, either fall onto a stacking table (not shown) forming the bottom of the stacking chute, or — for example in the time when a stack has to be removed from the stacking table is - on a carrying fork 20 (Fig. 1), the tines of which are formed by piston rods 21 passing through the stop rails 19 from piston-cylinder units 22, which in turn are fastened to a common carrier 23 which can be moved up and down along the stop rails 19. A holding device 24 is provided adjacent to the outlet of the ribbon conveyor 14. The holding device 24 has a pneumatic cylinder 25, the tubular piston rod 26 of which is led out of the cylinder 25 at both ends. At the lower end, the piston rod 26 carries a bellows-shaped suction cup 27, to which negative pressure is supplied through the piston rod 26 by a suction pump 28 mounted at the upper end of the piston rod 26. The suction pump 28 is operated with compressed air. The upper end of the cylinder 25 is on a bracket 29 is attached, which in turn is pivoted about a pin 30 in the vertical plane on a frame part 31 of the device. A boom 32 extends from the frame part 31, on which one end of a tension spring 33 is suspended. The other end of the tension spring 33 is suspended from a tab 34 fastened to the upper end of the piston rod 26. The direction of the tension spring 33 in the position of the holding device 24 shown in solid lines in FIG. 2 is indicated by the dash-dotted line 35. It can be seen that in this position the direction of the tension spring 33 extends above the pin 30, so that this spring 33 tends to hold the holding device 24 in the position shown in solid lines. However, as soon as the piston rod 26 is extended downward, the tension spring 33 acts in the opposite sense. A buffer 36 is also attached to the frame part 31, which prevents a hard impact of the bracket 29 on the frame part 31 when the cylinder 25 returns from the pivoted to the non-pivoted position.

Am Ausleger 32 ist auch ein elektromagnetisches Fünf/Zwei-Wege-Ventil 37 montiert, das über eine elektrische Leitung 38 betätigbar ist. An dieses Ventil 37 führt eine an eine Druckluftkquelle (nicht dargestellt) angeschlossene Zuführleitung 39.An electromagnetic five / two-way valve 37 is also mounted on the arm 32 and can be actuated via an electrical line 38. A supply line 39 connected to a compressed air source (not shown) leads to this valve 37.

In der unbetätigten Stellung leitet das Ventil 37 die in der Zuführleitung 39 anstehende Druckluft nicht weiter. In der einen Stellung verbindet das Ventil 37 die Zuführleitung 39 mit den Leitungen 40 und 41, mit dem Ergebnis, dass einerseits die Kolbenstange 26 mit dem Saugnapf 27 nach unten ausfährt und andererseits gleichzeitig die Saugpumpe 28 aktiviert wird. Dadurch saugt sich der Saugnapf 27 an dem oberen Druckereierzeugnis 13 des den Bändchenförderer 14 verlassenden Paares fest. Der Bändchenförderer 14 ist jedoch weiter wirksam und das vom Saugnapf 27 erfasste, obere Druckereierzeugnis 13 wird weitergeschoben und bringt damit - zusammen mit der Zugfeder 33 - den Zylinder 25 in die in Fig. 2 strichpunktiert dargestellte Stellung, womit das obere Druckereierzeugnis 13 von dem darunterliegenden abgehoben wird. In diesem Moment wird ein Trennfinger 42 (in Fig. 2 nur andeutungsweise dargestellt) vorgeschoben, der die Trennung der beiden Druckereierzeugnisse 13 so lange aufrechterhält, bis das untere dieser Druckereierzeugnisse auf den bereits vorhandenen Stapel S gefallen ist und die Zinken der Traggabel 20 ausgefahren sind und zur Aufnahme des ehemals oben in einem Paar Druckereierzeugnisse 13 gewesene Exemplar bereit sind.In the unactuated position, the valve 37 does not pass on the compressed air present in the supply line 39. In one position, the valve 37 connects the feed line 39 to the lines 40 and 41, with the result that on the one hand the piston rod 26 extends downward with the suction cup 27 and on the other hand the Suction pump 28 is activated. As a result, the suction cup 27 sucks on the upper printed product 13 of the pair leaving the ribbon conveyor 14. However, the ribbon conveyor 14 is still effective and the upper printed product 13 gripped by the suction cup 27 is pushed further and thus brings - together with the tension spring 33 - the cylinder 25 into the position shown in dash-dotted lines in FIG. 2, whereby the upper printed product 13 from the one below it is lifted off. At this moment, a separating finger 42 (only indicated in FIG. 2) is pushed forward, which maintains the separation of the two printed products 13 until the lower of these printed products has fallen onto the already existing stack S and the tines of the carrying fork 20 have been extended and are ready to receive the one 13 previously found in a pair of printed matter.

In der anderen Stellung des Ventils 37 wird eine um das untere Ende des Zylinders 25 führende Leitung 54 mit Druckluft versorgt, mit der Folge, dass die Saugpumpe 28 ausgeschaltet wird, der Saugnapf 27 das obere Druckereierzeugnis freigibt, die Kolbenstange 26 eingezogen und der Zylinder 25 in die Ausgangsstellung zurückgeführt wird.In the other position of the valve 37, a line 54 leading around the lower end of the cylinder 25 is supplied with compressed air, with the result that the suction pump 28 is switched off, the suction cup 27 releases the upper printed product, the piston rod 26 is drawn in and the cylinder 25 is returned to the starting position.

Aus Fig. 1 geht hervor, dass der Trennfinger 42 durch die Kolbenstange eines weiteren Pneumatikzylinders 43 gebildet ist, der an einem weiteren Rahmenteil 44 befestigt ist. In Fig. 1 ist auch sehr schematisch eine Steuereinrichtung 45 dargestellt. Diese weist eine durch den sägezahnförmigen seitlichen Rand des das Ende des Bändchenförderers 11 durchlaufenden Schuppenstromes periodisch unterbrochene Lichtschranke 46 auf, die über eine Leitung 47 an einen voreinstellbaren und rückstellbaren Zähler 48 angeschlossen ist. Dieser Zähler 48 wird über eine Leitung 49 durch eine programmierbare Steuereinheit 50 voreingestellt bzw. rückgestellt und liefert an diese über eine weitere Leitung 51 den erreichten Zählwert. Die Steuereinheit 50 ist über eine Leitung 52 mit einer Eingabeeinheit 53 verbunden, mit welcher eingegeben werden kann, wieviele Stapel oder Pakete à wieviele Druckereierzeugnisse gebildet werden sollen. Die Steuereinheit 50 steuert dann über die bereits erwähnte Zuleitung 38 das Ventil 37 an, und über eine weitere Leitung 54 sowie über weitere, nicht dargestellte Ventile, den Zylinder 43 sowie die Zylinder 22 an.1 that the separating finger 42 is formed by the piston rod of a further pneumatic cylinder 43, which is fastened to a further frame part 44. A control device 45 is also shown very schematically in FIG. 1. This has a periodically interrupted by the sawtooth-shaped lateral edge of the shingled stream passing through the end of the ribbon conveyor 11 Light barrier 46, which is connected via a line 47 to a presettable and resettable counter 48. This counter 48 is preset or reset via a line 49 by a programmable control unit 50 and supplies the counter value reached to it via a further line 51. The control unit 50 is connected via a line 52 to an input unit 53 which can be used to enter how many stacks or packets and how many printed products are to be formed. The control unit 50 then controls the valve 37 via the feed line 38 already mentioned, and the cylinder 43 and the cylinders 22 via a further line 54 and further valves, not shown.

Mit der beschriebenen Einrichtung lassen sich somit aus einem Schuppenstrom mit "Doppelbelegung" beliebig Stapel mit einer geraden oder einer ungeraden Anzahl Druckereierzeugnisse bilden. Dabei ist zu beachten, dass die vorgeschlagene Einrichtung nicht an Schuppenströme gebunden ist, in denen jeweils eine Ecke der Druckereierzeugnisse vorauslaufen, sondern auch bei herkömmlichen Schuppenströmen anwendbar ist, in denen eine Seitenkante der Druckereierzeugnisse vorlaufend ist.With the device described, any stack with an even or an odd number of printed products can be formed from a shingled stream with "double occupancy". It should be noted that the proposed device is not tied to shingled streams in which a corner of the printed products precedes, but can also be used with conventional shingled streams in which a side edge of the printed products is leading.

Während im beschriebenen Ausführungsbeispiel die Halteeinrichtung 24 im wesentlichen aus dem mit dem Pneumatikzylinder 25 verschwenkbaren Saugnapf 27 besteht, ist es denkbar, anstelle des Saugnapfes 27 ein endloses, mitlaufendes und gesteuert aktivierbares Saugband mit einem entsprechenden Verlauf vorzusehen. Bei dickeren Druckereierzeugnissen kann auch eine rein mechanische Haltevorrichtung vorgesehen sein, z.B. in der Art eines Trennfingers in Form eines Schwertes. Wichtig ist lediglich, dass das obere Druckereierzeugnis eines Paares vorübergehend daran gehindert wird, zusammen, d.h. gleichzeitig mit dem unteren Druckereierzeugnis, in den Stapelschacht 17 zu fallen.While in the described exemplary embodiment the holding device 24 essentially consists of the suction cup 27 which can be pivoted with the pneumatic cylinder 25, it is conceivable to provide an endless, rotating and controllably activatable suction belt instead of the suction cup 27 with a corresponding course. In the case of thicker printed products, a purely mechanical holding device can also be provided, for example in the manner of a separating finger in the form of a sword. It is only important that the upper printed product of a pair is temporarily prevented from falling into the stacking shaft 17 together, ie simultaneously with the lower printed product.

  1. Apparatus for the stacking of printing products (13), arriving in an imbricated formation, in which the printing products lie in pairs congruently one on top of the other, having a stack compartment (17) which can be charged from above and into which the end of a conveyor track (11, 14), provided with a counting device (46, 47, 48) opens out, characterised in that a retaining device (24), controlled by the counting device (46, 47, 48) is provided in the region of the end of the conveyor track (11, 14), which retaining device upon activation temporarily lifts the upper of a pair of printing products (13) off the lower printing product.
  2. Apparatus according to Claim 1, characterised in that the retaining device (24) has at least one suction cup (27), which upon activation can be lowered from above onto one of the pairs of printing products (13) and subsequently raised.
  3. Apparatus according to Claim 2, characterised in that the suction cup (27) is fitted at the end of a piston rod (26) of a cylinder-piston unit (25).
  4. Apparatus according to Claim 3, characterised in that the cylinder-piston unit (25) is suspended such that it can swivel in a vertical plane parallel to the conveying direction of the conveyor track (11, 14).
  5. Apparatus according to Claim 3, characterised in that the piston rod (26) is tubular and extends on both sides out of the cylinder of the cylinder-piston unit (25), and bears at the end away from the suction cup (27) a low-pressure source (28), supplying low pressure through the piston rod (26) to the suction cup (27).
  6. Apparatus according to Claims 4 and 5, characterised in that the one end of a tension spring (33) acts on the end of the piston rod (26) away from the suction cup (27), the tensile force of which tension spring draws the cylinder-piston unit (25) into the unswivelled position when the suction cup (27) is raised and draws it into the swivelled position when the suction cup (27) is lowered.
  7. Apparatus according to Claim 5, characterised in that the low-pressure source has a suction pump (28) operated by compressed air.
  8. Apparatus according to Claim 7, characterised in that an electromagnetic five/two-way valve (37) is provided, to supply compressed air both to the cylinder-piston unit (25) and to the suction pump (28).
  9. Apparatus according to one of Claims 1 to 8, characterised in that at least one separating finger (42), which can be moved into the stack compartment (17) simultaneously with the activation of the retaining device (24), is provided in order to ensure the separation of the raised printing product (13) from the one lying underneath.
