Description

Die Erfindung betrifft eine Vorrichtung zum Vereinzeln eines Falzbogens oder Einzelblattes aus einem Magazin, in dem die Bogen als Stapel bereitgestellt sind, mit einem schwenkbaren Sauger zum Abkippen des jeweils untersten Bogens vom Stapel, mit einem zwischen den abgekippten Bogen und den Stapel bewegbaren Stapelheber, und mit einer den vereinzelten Bogen aus dem Magazin ausfördernden und einem Transportkanal einer Transporteinrichtung zuführenden Abzugsvorrichtung, sowie mit einer Antriebseinrichtung zur taktgemäßen Betätigung von Sauger und Stapelheber.The invention relates to a device for separating a folded sheet or single sheet from a magazine in which the sheets are provided as a stack, with a pivotable suction for tipping the respective lowermost sheet from the stack, with a movable between the tipped sheet and the stack stack lifter, and with a the individual sheet auszufördernden from the magazine auszufördernden and a transport channel of a transport device feeding withdrawal device, as well as with a drive device for the clock actuation of vacuum cleaner and stack lifter.

Vereinzelungseinrichtungen der genannten Art sind als Anlegestationen in Zusammentragmaschinen bekannt. Mehrere Anlegestationen sind in einer Reihe oberhalb des Transportkanals der Transporteinrichtung angeordnet, dem die jeweils aus den Anlegestationen vereinzelten Bogen zur Stapelbildung zugeführt werden.Separation devices of the type mentioned are known as landing stations in gathering machines. Several mooring stations are arranged in a row above the transport channel of the transport device to which the separated from the docking stations sheet for stack formation are supplied.

Aus der DE 14 86 744 B ist eine Zusammentragmaschine mit Anlegestationen nach dem Querabzugsprinzip bekannt. Mittels einer Abzugstrommel mit Greifermechanismus wird der jeweils unterste, vom Stapel abgekippte Bogen erfasst, vom Stapel abgezogen und auf einer Zwischenauflage abgelegt, von der ein Mitnehmer der Transporteinrichtung den Bogen zur Stapelbildung abstreift.From the DE 14 86 744 B is a gathering machine with mooring stations after the Querabzugsprinzip known. By means of a take-off drum with a gripper mechanism, the respective lowermost, tipped from the stack sheet is detected, withdrawn from the stack and stored on an intermediate support, from which a driver of the transport device strips the sheet for stacking.

Aus der DE 196 16047 A1 ist eine Zusammentragmaschine mit Anlegestationen nach dem Längsabzugsprinzip bekannt, jeweils bestehend aus einem den Falzbogenstapel im Magazin unter Freilassung eines Falzkantenbereiches tragenden und den untersten Bogen taktgemäß vorschiebenden Förderband, einem den vorgeschobenen Bogen übernehmenden und weitertransportierenden Abzugsfördersystem, gebildet von Beschleunigungsrollen, und aus einem zum Transportkanal hin geneigten Klemmförderer, welcher den vereinzelten Bogen bei synchroner Förderbewegung vor dem jeweiligen Mitnehmer der Transporteinrichtung auf den bis dahin gebildeten Stapel ablegt. DE 1937 080 A1 offenbart eine Vorrichtung gemäß dem einleitenden Teil des Anspruchs 1.From the DE 196 16047 A1 a gathering machine with landing stations according to the longitudinal extraction principle is known, each consisting of a Falzbogenstapel in the magazine with the release of a folded edge and bearing the lowest sheet in time advancing conveyor belt, the advanced bow receiving and further transporting deduction conveyor system, formed by acceleration rollers, and from one to the transport channel out inclined clamping conveyor, which deposits the separated sheet in synchronous conveying movement in front of the respective carrier of the transport device on the hitherto formed stack. DE 1937 080 A1 discloses a device according to the introductory part of claim 1.

Das Vereinzeln erfolgt in den bekannten Anlegestationen mit der im Oberbegriff genannten Sauger-Stapelheber-Anordnung. In definierter zeitlicher Abfolge wird zunächst der Sauger in einem Randbereich gegen die Stapelunterseite geschwenkt, der unterste Bogen angesaugt und vom Stapel durch Zurückschwenken des Saugers abgekippt. Anschließend wird der Stapelheber zwischen den abgekippten Bogen und den Stapel bewegt, um den verbleibenden Stapel beim Abziehen des separierten Bogens zu stützen bzw. anzuheben. Dabei kann von dem Stapelheber Blasluft ausgegeben werden, um die Reibung zwischen Bogen und Stapel zu reduzieren. Der Zyklus endet mit dem Zurückschwenken des Stapelhebers, zum Freilegen des entsprechenden Randbereichs für den dann wieder gegen die Stapelunterseite schwenkenden Sauger.The separation takes place in the known landing stations with the vacuum cleaner stacker arrangement mentioned in the preamble. In a defined chronological sequence, the sucker is first pivoted in an edge region against the bottom of the stack, sucked the bottom sheet and dumped from the stack by pivoting back of the nipple. Subsequently the stack lifter is moved between the dumped sheets and the stack to support the remaining stack upon removal of the separated sheet. In this case, can be output from the stack lifter blowing air to reduce the friction between the sheet and stack. The cycle ends with the pivoting back of the stack lifter, to expose the corresponding edge region for the then again against the bottom of the stack swinging suckers.

Bei den bekannten Anlegestationen sind der Sauger und der Stapelheber von separaten, entsprechend der dargelegten zeitlichen Abfolge phasenverschoben angeordneten Antriebskurven und zugeordneten Kurvenrollenhebeln gesteuert, wobei aufgrund der Modularisierung von Zusammentragmaschinen mit stationsweise einsetz- und austauschbaren Anlegestationen jede einzelne Anlegestation eine solche aus zwei Antriebskurven bestehende Antriebseinrichtung aufweist. Antriebskurven sind vergleichsweise teure Bauteile. Im Hinblick auf die große Anzahl Anlegestationen, mit der eine einzelne Zusammentragmaschine ausgestattet sein kann, ist der diesbezügliche Aufwand nicht unerheblich.In the known docking stations of the vacuum cleaner and the stack lifter are controlled by separate, according to the timing shown out of phase arranged drive curves and associated cam followers, which due to the modularization of collators with station wise insertable and replaceable docking stations each docking station has such consisting of two drive curves drive means , Drive curves are comparatively expensive components. In view of the large number of mooring stations, with which a single gathering machine can be equipped, the related effort is not insignificant.

Der Erfindung liegt nun die Aufgabe zugrunde, eine Vorrichtung zum Vereinzeln eines Falzbogens oder Einzelblatts aus einem Magazin gemäß dem Oberbegriff des Anspruchs 1 zu schaffen, die einen einfacheren Aufbau mit weniger Teilen besitzt und dennoch funktionssicher ist.The invention is an object of the invention to provide a device for separating a folded sheet or single sheet from a magazine according to the preamble of claim 1, which has a simpler structure with fewer parts and yet is functionally reliable.

Die Steuerung des Saugers und des Stapelhebers mit einer einzigen Antriebskurve und nur einem zugeordneten Kurvenrollenhebel ermöglicht einen einfachen Aufbau mit wenigen Teilen. Die Funktionssicherheit ist gegeben, da die Bewegungen mechanisch erzeugt und mechanisch miteinander gekoppelt sind. Der Erfindung liegt die Idee zugrunde, die bislang nacheinander erfolgenden Bewegungen von Sauger und Stapelheber zeitgleich durchzuführen, aber trotzdem die für die Funktion erforderliche oben beschriebene zeitliche Abfolge an den entsprechenden Stellen einzuhalten. Hierfür können die jeweiligen Bewegungen von Sauger und Stapelheber durch die zwischengeschalteten Übertragungsgetriebe zueinander verzerrt werden. So kann die Bewegung des Saugers auf den Stapel zu gleichzeitig mit der Bewegung des Stapelhebers vom Stapel weg erfolgen. Ebenso verhält es sich mit der Abkippbewegung des Saugers und der Bewegung des Stapelhebers zwischen abgekippten Bogen und Stapel.The control of the nipple and the stack lifter with a single drive curve and only one associated cam follower allows a simple construction with few parts. The functional reliability is given because the movements are generated mechanically and mechanically coupled with each other. The invention is based on the idea to simultaneously carry out the successively successive movements of suction and stack lift, but still comply with the time sequence described above required for the function at the appropriate locations. For this purpose, the respective movements of suckers and stack lifters can be distorted by the intermediate transmission gear to each other. Thus, the movement of the nipple onto the stack may occur simultaneously with the movement of the stack lifter away from the stack. The same applies to the tilting movement of the nipple and the movement of the stack lifter between dumped sheet and stack.

Eine bevorzugte Ausbildungsform der Erfindung sieht vor, dass die Bewegung des einen Kurvenrollenhebels derart auf den Sauger und den Stapelheber übertragen wird, dass sich zumindest während einer Bewegungsphase der Sauger und der Stapelheber zeitversetzt zueinander in Bewegung setzen. Hierdurch ist gewährleistet, dass der Sauger und/oder der Stapelheber an den entsprechenden Stellen mit dem funktionell erforderlichen Hub vorbeibewegt sind, bevor das jeweils andere Element (Stapelheber oder Sauger) in diese Stelle bewegt wurde. Die jeweiligen Gesamthübe von Sauger und Stapelheber können hierdurch auf einen jeweils funktionell erforderlichen Mindesthub begrenzt bleiben, was konstruktive Vorteile in der Auslegung der Führungsgetriebe für Sauger und Stapelheber mit sich bringt.A preferred embodiment of the invention provides that the movement of the one cam follower lever is transmitted to the nipple and the stack lifter such that, at least during a movement phase, the nipple and the stack lifter are set in motion with a time delay. This ensures that the sucker and / or the stack lifter are moved past the appropriate places with the functionally required stroke before the other element (stack lifter or sucker) has been moved into this position. The respective total strokes of nipple and stack lifters can thereby be limited to a respective functionally required minimum stroke, which brings constructive advantages in the design of the guide gear for vacuum cleaner and stack lifter with it.

Mit Vorteil bewegt sich in einer ersten Bewegungsphase der Stapelheber vom Stapel weg, während die Bewegung des Sauger auf den untersten Bogen zu erst später einsetzt. Vorteilhaft ist weiterhin, dass sich in einer zweiten Bewegungsphase der Sauger vom Stapel wegbewegt, während die Eintauchbewegung des Stapelhebers zwischen den abgekippten Bogen und den Stapel erst später einsetzt. Vorzugsweise ist zwischen der zweiten und der ersten Bewegungsphase eine Rast vorgesehen.Advantageously, in a first phase of movement, the stack lifter moves away from the stack, while the movement of the sucker on the lowermost sheet begins later. A further advantage is that in a second phase of movement of the sucker moves away from the stack, while the dipping movement of the stack lifter between the tipped sheet and the stack begins later. Preferably, a catch is provided between the second and the first movement phase.

Bei der erfindungsgemäßen Vereinzelungseinrichtung ist die Antriebskurve endlos ausgebildet und vorzugsweise kontinuierlich drehangetrieben.In the singulator according to the invention, the drive curve is endless and preferably rotationally driven.

Eine bevorzugte Ausbildungsform der Erfindung sieht vor, dass das jeweilige Übertragungsgetriebe für den Sauger und/oder den Stapelheber eine Schwinge umfasst, mit welcher der Sauger bzw. der Stapelheber über eine Koppelstange verbunden ist, wobei während einer Bewegungsphase die Koppelstange und die Schwinge eine Deck- oder Strecklage aufweisen. Vorzugsweise fällt die Deck- oder Strecklage mit einer Endstellung der Sauger- bzw. Stapelheberbewegung zusammen.A preferred embodiment of the invention provides that the respective transmission gear for the nipple and / or the stack lifter comprises a rocker, with which the nipple or the stack lifter is connected via a coupling rod, wherein during a movement phase, the coupling rod and the rocker a cover or stretched position. Preferably, the cover or stretched position coincides with an end position of the suction or Stapelheberbewegung.

Die jeweiligen Schwingen für die beiden Übertragungsgetriebe können in einer gemeinsamen Schwinge integriert sein, wodurch sich die Teilezahl weiter reduziert und nur eine Lagerstelle realisiert werden muss. Vorzugsweise sind die Schwingen bzw. die gemeinsame Schwinge mit dem einen Kurvenrollenhebel über eine Koppelstange verbunden.The respective rockers for the two transmission gear can be integrated in a common rocker, which further reduces the number of parts and only one bearing must be realized. Preferably, the rockers or the common rocker are connected to the cam follower lever via a coupling rod.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Ansprüchen, der nachfolgenden Beschreibung eines Ausführungsbeispiels sowie der Zeichnung. Es zeigt die Fig. eine perspektivische Ansicht einer erfindungsgemäßen Vereinzelungsvorrichtung.Further advantageous features emerge from the dependent claims, the following description of an embodiment and the drawing. The FIG. 1 shows a perspective view of a separating device according to the invention.

Die Vereinzelungseinrichtung 1 dient zum Vereinzeln eines Falzbogens 2 aus einem Magazin 4, in dem die Falzbogen 2 als Stapel 3 bereitgestellt sind. Der Stapel 3 liegt im Magazin 4 unter Freilassung eines Falzkantenbereiches auf einem vor und zurück bewegten Förderband 5 auf, welches den jeweils untersten Falzbogen 2 taktgemäß in Ausförderrichtung 6 vorschiebt zur Übergabe an eine nicht weiter dargestellte, den vereinzelten Falzbogen 2 aus dem Magazin 3 ausfördernde und einem Transportkanal einer Transporteinrichtung zuführende Abzugsvorrichtung.The separating device 1 is used for separating a folded sheet 2 from a magazine 4, in which the folded sheets 2 are provided as a stack 3. The stack 3 is in the magazine 4, leaving a folded edge region on a moving back and forth conveyor belt 5, which advances the respective lowermost signatures 2 clockwise in Ausförderrichtung 6 for transfer to a not shown, the occasional folded sheet 2 ausfördernde from the magazine 3 and a transport channel of a transport device feeding deduction device.

Das eigentliche Vereinzeln bzw. Trennen des Falzbogens 2 vom Stapel 3 erfolgt mit einer Sauger- und Stapelheberanordnung 10, 20. Mittels eines gegen den freigelassenen Falzkantenbereich schwenkbaren Saugers 11 wird dabei der jeweils unterste Falzbogen 2 vom Stapel 3 abgekippt, wobei der Sauger 11 eine Schwenkbewegung um eine in der Auflagefläche liegende, zur Ausförderrichtung 6 parallele Schwenkachse vollführt. Ein Stapelheber 21 wird dann in die Lücke zwischen den abgekippten Falzbogen 2 und den Stapel 3 bewegt, um den Stapel 3 beim Abziehen des separierten Falzbogens 2 zu stützen bzw. anzuheben. Dabei wird von der eingetauchten Spitze des Stapelhebers 21 Blasluft 22 ausgegeben, um die Reibung zwischen Falzbogen 2 und Stapel 3 zu reduzieren.The actual singling or separation of the signatures 2 from the stack 3 takes place with a vacuum and stack lifter arrangement 10, 20. By means of a pivotable against the released folding edge region suction cup 11 while the lowest sheet 2 is tipped from the stack 3, wherein the sucker 11 is a pivoting movement around a lying in the support surface, parallel to the Ausförderrichtung 6 pivot axis performs. A stack lifter 21 is then moved into the gap between the dumped signatures 2 and the stack 3 to support the stack 3 upon removal of the separated signatures 2. In the process, blown air 22 is emitted from the submerged tip of the stack lifter 21 in order to reduce the friction between folded sheet 2 and stack 3.

Erfindungsgemäß werden der Sauger 11 und der Stapelheber 21 von einer Antriebseinrichtung 30 betätigt, welche nur eine Antriebskurve 32 mit nur einem zugeordneten Kurvenrollenhebel 33 aufweist. Die als Doppelkurve ausgebildete Antriebskurve 32 befindet sich auf einer kontinuierlich drehangetriebenen, in einem nicht weiter dargestellten Gestell gelagerten Antriebswelle 31. Der mit Kurvenrollen 34 im Formschluss an der Antriebskurve 32 anliegende Kurvenrollenhebel 33 ist auf einer gestellfesten Achse 35 schwenkbar gelagert.According to the invention, the sucker 11 and the stack lifter 21 are actuated by a drive device 30 which has only one drive cam 32 with only one associated cam follower lever 33. Trained as a double cam drive curve 32 is located on a continuously rotationally driven, mounted in a frame not shown drive shaft 31. The cam follower 34 with cam rollers 34 in positive engagement with the drive cam 32 is pivotally mounted on a frame-fixed axis 35.

Die Schwenkbewegung des einen Kurvenrollenhebels 33 wird mittels einer am Kurvenrollenhebel 33 angelenkten Koppelstange 36 auf eine Schwinge 37 übertragen, die um eine an einem gestellfesten Halter 39 angeordnete Achse 38 schwenkbar gelagert ist. Im Ausführungsbeispiel sind die Achsen 35, 38 um 90° zueinander versetzt angeordnet. An der Schwinge 37 sind an zwei verschiedenen Enden jeweils eine Koppelstange 40 bzw. 41 angelenkt, die dann mit der Saugeranordnung 10 bzw. der Stapelheberanordnung 20 verbunden sind.The pivoting movement of the cam follower lever 33 is transmitted by means of a coupling rod 36 articulated on the cam follower lever 33 to a rocker arm 37, which is pivotably mounted about an axle 38 arranged on a frame-fixed holder 39. In the exemplary embodiment, the axes 35, 38 are arranged offset by 90 ° to each other. On the rocker 37 each have a coupling rod 40 and 41 are articulated at two different ends, which are then connected to the sucker assembly 10 and the stack lifter assembly 20.

Die Saugeranordnung 10 besteht aus einem viergliedrigen Koppelgetriebe als Führungsgetriebe für den Sauger 11, mit an einem gestellfesten Halter 15 angelenkten ersten und zweiten Lenkern 13, 14 und einer als Saugeraufnahme 12 ausgebildeten Koppel. Die genannte Koppelstange 40 ist auf der Achse des Drehgelenks zwischen Saugeraufnahme 12 und zweitem Lenker 14 gelenkig angeordnet. Aus Darstellungsgründen ist in der Fig. der vordere Teil des Halters 15 weggelassen.The nipple assembly 10 consists of a four-link coupling gear as a guide gear for the nipple 11, with hinged to a frame-fixed holder 15 first and second links 13, 14 and designed as a suction cup 12 coupling. Said coupling rod 40 is articulated on the axis of the rotary joint between suction cup 12 and second link 14. For the sake of illustration, the front part of the holder 15 is omitted in the figure.

Die Stapelheberanordnung 20 besteht aus einem viergliedrigen Koppelgetriebe als Führungsgetriebe für den Stapelheber 21, mit an einem gestellfesten Halter 26 angelenkten ersten und zweiten Lenkern 24, 25 und einer als Aufnahme 23 für den Stapelheber 21 ausgebildeten Koppel. Hier ist die genannte Koppelstange 41 an der Aufnahme 23 angelenkt.The stack lifter assembly 20 consists of a four-link coupling gear as a guide gear for the stack lifter 21, with hinged to a frame-fixed holder 26 first and second links 24, 25 and as a receptacle 23 for the stack lifter 21st trained paddock. Here, said coupling rod 41 is hinged to the receptacle 23.

Ein Vereinzelungsvorgang ist bereits oben beschrieben. Die Besonderheit ist, dass die an sich nacheinander erfolgenden Bewegungen von Sauger 11 und Stapelheber 21 von einer einzigen Antriebskurve 32 mit nur einem daran anliegenden Kurvenrollenhebel 33 gesteuert sind. Die Fig. zeigt die Phase des Ausförderns eines Falzbogens 2. Der Stapelheber 21 verharrt in seiner ersten Endstellung zwischen dem zuletzt vereinzelten Falzbogen 2 und dem darüber liegenden Stapel 3, während sich der Sauger 11 in abgekippter Stellung als dessen erste Endstellung befindet. Die Antriebskurve 32 weist für diese Phase eine Rast auf.A singulation process is already described above. The peculiarity is that the successive movements of the sucker 11 and the stack lifter 21 are controlled by a single drive cam 32 with only one cam follower lever 33 resting against it. The stack lifter 21 remains in its first end position between the last separated signatures 2 and the stack above 3, while the sucker 11 is in tilted position as its first end position. The drive cam 32 has a stop for this phase.

Sobald der ausgeförderte Falzbogen 2 die Wirkstelle von Sauger 11 und Stapelheber 21 passiert hat, bewegt sich in einer ersten Bewegungsphase der Stapelheber 21 aus dem Stapel 3 heraus, während der Sauger 11 gegen den freigelassenen Falzkantenbereich geschwenkt wird. Dadurch dass sich zu Beginn dieser Bewegungsphase die Koppelstange 40 in einer Strecklage 42 mit der Schwinge 37 befindet, setzt die Bewegung des Saugers 11 zeitversetzt zur Bewegung des Stapelhebers 21 ein. Denn erst nach einer gewissen Schwenkbewegung der Schwinge 37 ist eine Verschiebung des Anlenkpunktes der Koppelstange 40 an der Saugeraufnahme 12 wirksam. Hierdurch ist gewährleistet, dass der Stapelheber 21 vom besagten Falzkantenbereich wegbewegt ist, bevor der Sauger 11 den Stapel 3 kontaktiert.As soon as the delivered folded sheet 2 has passed the point of action of the nipple 11 and the stack lifter 21, in a first phase of movement the stack lifter 21 moves out of the stack 3 while the nipple 11 is pivoted against the released folded edge area. The fact that the coupling rod 40 is in an extended position 42 with the rocker 37 at the beginning of this movement phase, the movement of the nipple 11 is a time-delayed to the movement of the stack lifter 21 a. Because only after a certain pivoting movement of the rocker 37 is a displacement of the articulation point of the coupling rod 40 on the suction cup 12 effective. This ensures that the stack lifter 21 is moved away from said folded edge region before the sucker 11 contacts the stack 3.

Unmittelbar an diese erste Bewegungsphase schließt sich mit einer Umkehrbewegung eine zweite Bewegungsphase an, in welcher der Sauger 11 den angesaugten Falzbogen 2 vom Stapel 3 abkippt. Gleichzeitig bewegt sich der Stapelheber 21 in die Lücke zwischen den abgekippten Falzbogen 2 und den Stapel 3. Die gemeinsame Antriebsbewegung wird dabei durch die unterschiedliche Anlenkung der Koppelstangen 40, 41 an der Schwinge 37 derart verzerrt auf die Sauger- und Stapelheberanordnungen 10, 20 übertragen, dass der Stapelheber 21 erst dann den Stapel 3 erreicht, wenn eine ausreichende Lücke vom Sauger 11 bereits gezogen wurde.Immediately following this first movement phase is followed by a reverse movement, a second movement phase, in which the sucker 11 tilts the sucked folded sheet 2 from the stack 3. At the same time, the stack lifter 21 moves into the gap between the tilted folded sheet 2 and the stack 3. The common drive movement is thereby distorted by the different articulation of the coupling rods 40, 41 on the rocker 37 transmitted to the suction and Stapelheberanordnungen 10, 20 that the stack lifter 21 only reaches the stack 3 when a sufficient gap has already been pulled by the sucker 11.

Nachdem Sauger 11 und Stapelheber 21 ihre jeweilige erste Endstellung erreicht haben, beginnt die bereits genannte Rast, in welcher der nun vereinzelte Falzbogen 2 von dem Förderband 5 ausgeschoben werden kann.After the nipple 11 and stack lifter 21 have reached their respective first end position, the already mentioned rest begins, in which the now separated signatures 2 can be pushed out of the conveyor belt 5.

Im Umkehrpunkt des Stapelhebers 21 als dessen zweite Endstellung könnte ebenfalls eine Streck- oder Decklage der zugeordneten Koppelstange 41 mit der Schwinge 37 vorliegen, um ein zeitversetztes Bewegen von Sauger 11 und Stapelheber 21 zu erreichen.At the reversal point of the stack lifter 21 as its second end position could also be a stretch or cover layer of the associated coupling rod 41 is present with the rocker 37 to achieve a time-delayed movement of the sucker 11 and stack lifter 21.

Im Ausführungsbeispiel jedoch ist ein gewisser Überhub in der Bewegung des Stapelhebers 21 vorgesehen, d.h. der Stapelheber 21 bewegt sich weiter vom Stapel 3 weg als funktionell erforderlich, sodass bei dessen Rückbewegung der notwendige Zeitversatz entsteht, bis der Stapelheber 21 den Stapel 3 bzw. die vom Sauger 11 gezogene Lücke erreicht.However, in the embodiment, there is some overstroke in the movement of the stack lifter 21, i. the stack lifter 21 continues to move away from the stack 3 as functionally required, so that upon its return movement the necessary time offset arises until the stack lifter 21 reaches the stack 3 or the gap drawn by the sucker 11.
