Description

Die Erfindung betrifft eine Vorrichtung zur Probebogenentnahme an einem Ausleger einer Bogendruckmaschine mit einer Bogenfördereinrichtung, einem in den Bogenablageweg über dem Bogenstapel einfahrbaren Bogenhochhalter und einem Bogenanschlag für die Vorderkante der Bogen, der aus einer an den Bogenstapel angestellten Anschlagposition in eine die Entnahme von Probebogen ermöglichende Entnahmeposition verfahrbar ist.The invention relates to a device for taking samples on a delivery of a sheetfed press with a Sheet conveying device, one in the sheet deposit path retractable sheet holder and one Sheet stop for the leading edge of the sheet made from a on the sheet stack in a stop position the removal position that enables the removal of sample sheets is movable.

Vorrichtungen zur Probebogenentnahme sind in unterschiedlicher Ausgestaltung bekannt. Sie dienen dazu, während des Druckbetriebs die Entnahme von Probebogen zur Kontrolle des Druckergebnisses zu ermöglichen.Devices for taking samples are different Design known. They are used during the Printing company to take test sheets to check the To enable print results.

Bei einer aus der DE 42 13 032 A1 bekannten Vorrichtung der angegebenen Art wird zur Entnahme von Probebogen ein Hilfsanschlag eingeschwenkt und auf den dem Probebogen vorausgehenden Vorgängerbogen abgesetzt, wodurch die obersten Bogen auf dem Auslagestapel fixiert werden. Beidseitig des Hilfsanschlags angeordnete Bläser blasen in den Auslagestapel hinein und heben den ankommenden Probebogen über den Hilfsanschlag hinweg. Die Vorderanschläge werden so zurückgeklappt, daß der Probebogen diese nicht mehr erreicht und der Probebogen durch seine kinetische Energie über die Vorderkante des Stapelgrundrisses hinaus gefördert wird. Gleichzeitig werden Bogenhochhalter über dem Probebogen und unter dem ersten Folgebogen eingeschwenkt. Der auf diese Weise separierte Probebogen kann nun an seiner Vorderkante mit der Hand gegriffen und entnommen werden.In a device known from DE 42 13 032 A1 specified type, an auxiliary stop is used to take out test sheets swung in and on the one preceding the sample sheet Predecessor arch offset, creating the top arch be fixed on the delivery pile. On both sides of the auxiliary stop arranged blowers blow into the delivery pile and lift the incoming test sheet over the auxiliary stop away. The front stops are folded back so that the test sheet no longer reaches this and the kinetic energy of the sample sheet over the leading edge of the stack floor plan is promoted. At the same time, sheet holders are placed over the sample sheet and swung in under the first following sheet. The one on this Wise separated test sheets can now be on its front edge gripped and removed by hand.

Aus der DE 32 30 436 C2 ist weiterhin eine Vorrichtung zur Bogenablage und Probebogenentnahme bekannt, bei der die Bogen von einem Nachgreifer bis zu einem Bogenanschlag gefördert werden. Zur Probebogenentnahme wird der Bogenanschlag entfernt und eine pneumatische Bogentrenneinrichtung eingeschwenkt und der Nachgreifer derart umgesteuert, daß die Probebogen über die Vorderkante des Bogenauslagestapels hinaus gefördert und abgelegt werden. Nachdem eine wählbare Anzahl von Probebogen abgelegt ist, wird über diesen eine Hilfsanschlageinrichtung eingeschwenkt, auf der die nachfolgenden Bogen mit zurückgesteuertem Nachgreifer abgelegt werden. Die vorstehenden Probebogen können zwischen der Bogentrenneinrichtung und der Hilfsanschlageinrichtung herausgenommen werden.From DE 32 30 436 C2 there is also a device for Sheet deposit and sample sheet removal known, in which the Bow from a gripper to a sheet stop be promoted. The sheet stop is used to take the sample sheet removed and a pneumatic sheet separator swiveled in and the gripper reversed so that the test sheets over the front edge of the sheet delivery stack be promoted and filed. Having a selectable Number of test sheets is stored, this one Auxiliary anchor device pivoted on the following Sheets are deposited with the re-gripper controlled become. The sample sheets above can be used between the Sheet separator and the auxiliary stop device removed become.

Das Entnehmen der Probebogen wird im allgemeinen von Hand durchgeführt. Nachdem der Drucker den Bogenanschlag in die Entnahmeposition gefahren hat, greift er mit der Hand über diesen hinweg in den Zwischenraum zwischen den von dem Bogenhochhalter hochgehaltenen Folgebogen und dem gegebenenfalls mit Hilfe von Blaseinrichtungen leicht angehobenen Probebogen, ergreift dann diesen und zieht ihn aus dem Ausleger heraus. Da sich in einem vergleichsweise geringem Abstand über dem Bogenstapel die Bewegungsbahn der die Bogen in den Ausleger tranportierenden Bogenfördereinrichtung, zum Beispiel eines Kettengreifersystems, befindet, besteht das Bedürfnis, Schutzvorrichtungen vorzusehen, die die Bewegungsbahn der Bogenfördereinrichtung abschirmen und eine Berührung der sich bewegenden Elemente der Bogenfördereinrichtung bei der Probebogenentnahme verhindern. The sample sheets are generally removed by hand carried out. After the printer places the sheet stop in the Has reached the removal position, he reaches over with his hand this into the space between those of the Sheet holder holding up the following sheet and if necessary slightly raised with the aid of blowing devices Trial sheet, then grabs it and pulls it out of the delivery out. Because in a comparatively small Distance above the stack of sheets the trajectory of the Sheets transporting sheets into the delivery, for example a chain gripper system, there is a need to provide protection devices that shield the path of movement of the sheet conveyor and a touch of the moving elements of the sheet conveyor prevent when taking the sample sheet.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art auf einfache und kostengünstige Weise derart weiterzubilden, daß eine Berührung der Bogenfördereinrichtung mit der Hand bei der Probebogenentnahme nicht eintreten kann.The invention has for its object a device of the type mentioned in the simple and inexpensive Way to develop such that a touch of the sheet conveyor by hand when taking the sample sheet cannot occur.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß an dem Bogenhochhalter ein gemeinsam mit diesem in den Bogenablageweg über dem Bogenstapel einfahrbarer Eingriffschutz angebracht ist, der sich zwischen der Bogenfördereinrichtung und dem Eingriffsbereich längs des Bogenanschlags bzw. der Vorderkante des Bogenstapels erstreckt.According to the invention this object is achieved in that the sheet holder together with this in the sheet storage path Retractable tamper evident over the sheet stack is attached, which is between the sheet conveyor and the engagement area along the arch stop or the leading edge of the sheet stack extends.

Durch die erfindungsgemäße Anbringung eines Eingriffschutzes an dem Bogenhochhalter wird auf einfache Weise und mit geringem baulichen Aufwand eine sichere Abschirmung des Eingriffsbereichs für die Probebogenentnahme auch über dem Bogenstapel erreicht, ohne die normale Boganablage zu beeinträchtigen. Der Eingriffschutz kann erfindungsgemäß als geschlossene oder durchbrochene Wand, als Gitter, oder Gewebe ausgebildet und aus Blech, Draht oder Kunststoff hergestellt sein. Um auch während der Bogenauslage einen Eingriff in den Ablagebereich über dem Bogenstapel zu verhindern, kann nach einem weiteren Vorschlag der Erfindung vorgesehen sein, daß der Bogenanschlag eine Vielzahl von in geringem Abstand parallel nebeneinander angeordneten Fingern aufweist und daß der Eingriffschutz in der ausgefahrenen Stellung des Bogenhochhalters bis dicht an die Finger des Bogenanschlags heranreicht.By attaching a tamper protection according to the invention on the bow holder is easy Safe and with little construction effort Shielding the intervention area for the sample sheet removal also reached above the sheet stack without the normal one Interfering with bow rest. Protection against intrusion can according to the invention as a closed or perforated wall, designed as a grid or fabric and made of sheet metal, wire or plastic. To also during the Sheet delivery an intervention in the storage area above the Preventing sheet piles can be made according to another suggestion the invention provide that the bow stop a variety of closely spaced in parallel arranged fingers and that the tamper protection in the extended position of the bow holder up to the fingers of the bow stop.

Nach einem weiteren Vorschlag der Erfindung kann der über den Bogenstapel einfahrbare Eingriffschutz eine Betätigungsvorrichtung für einen verfahrbaren Hilfsanschlag bilden, an den Probebogen mit ihrer Vorderkante anlegbar sind, wobei der Hilfsanschlag durch Einfahren des Eingriffschutzes in den Bogenablageweg aus seiner Anschlagposition in eine die Probebogenentnahme zulassende Entnahmeposition verfahrbar ist. Diese Weiterbildung der Erfindung ermöglicht mit einfachen Mitteln die Anordnung eines vom Bogenstapel abgestellten Hilfsanschlags, der nach dem Abstellen des Bogenanschlags eine versetzte Probebogenauslage ermöglicht, ohne daß es hierzu aufwendiger Betätigungseinrichtungen zum Verfahren des Hilfsanschlags für die Probebogenentnahme bedarf. Der Hilfsanschlag besteht vorzugsweise aus einem drehbar gelagerten, zweiarmigen Hebel, dessen einer Hebelarm den Anschlag für die Probebogen bildet und dessen anderer Hebelarm durch den Eingriffschutz beim Einfahren in den Bogenablageweg verschwenkbar ist.According to a further proposal of the invention, the the sheet stack retractable intervention protection an actuator for a movable auxiliary stop, can be placed on the test sheet with their leading edge, the auxiliary stop by retracting the tamper protection in the sheet delivery path from its stop position in a removal position that allows the sample sheet to be removed is movable. This development of the invention enables the arrangement of one of the Sheet pile parked auxiliary stop, which after the Parking the sheet stop, an offset sample sheet delivery enables, without the need for expensive actuators on the procedure of the auxiliary stop for the Sample sheet collection required. The auxiliary stop is preferably there from a rotatable, two-armed lever, one lever arm forms the stop for the test sheet and its other lever arm through the intervention protection is pivotable when entering the sheet delivery path.

Dem in Figur 1 ausschnittsweise dargestellten Ausleger 1 einer Bogendruckmaschine ist ein Kettenfördersystem 2 zugeordnet, das in stetiger Folge bedruckte Bogen 3 einem Bogenstapel 4 zuführt. Die Zuführung erfolgt hierbei in der Weise, daß die Bogen 3 in der durch einen Pfeil 5 angegebenen Richtung mit Hilfe von Greifern 6 über den Bogenstapel 4 transportiert und dann an einer bestimmten Stelle losgelassen werden. Unterstützt von Blaseinrichtungen fallen die Bogen 3 dann auf den Bogenstapel 4, wobei sie aufgrund ihres aus der horizontalen Förderbewegung resultierenden und gegebenenfalls durch eine Bremsvorrichtung verminderten Bewegungsimpulses mit ihrer Vorderkante an einem Bogenanschlag 7 anstoßen, der an die vordere Stapelfläche 8 des durch die abgelegten Bogen gebildeten Bogenstapels 4 angestellt ist. Der Bogenanschlag 7 besteht aus einer größeren Anzahl von in einem Abstand parallel nebeneinander auf einer drehbar gelagerten Welle 9 befestigten Fingern 10, die gemeinsam eine ebene Anschlagfläche 11 bilden. Der Zwischenraum zwischen den Fingern 10 ist so klein bemessen, daß man nicht mit der Hand hindurchgreifen kann.The boom 1 shown in detail in FIG. 1 a chain conveyor system 2 is assigned to a sheet-fed printing machine, the sheet 3 printed in a continuous sequence Sheet stack 4 feeds. The feed takes place in the Way that the bow 3 in the direction indicated by an arrow 5 Direction with the help of grippers 6 over the sheet stack 4 transported and then released at a certain point become. Supported by blowing devices, the fall Sheet 3 then on the sheet stack 4, being due hers resulting from the horizontal conveying movement and possibly reduced by a braking device Movement impulse with its leading edge at a sheet stop 7 bump on the front stacking surface 8 of the formed by the deposited sheet stack 4 sheets is. The sheet stop 7 consists of a larger one Number of at a distance in parallel next to each other a rotatably mounted shaft 9 attached fingers 10, which together form a flat stop surface 11. The gap between fingers 10 is so small that you can't reach through with your hand.

Auf der dem Bogenstapel 4 abgekehrten Seite des Bogenanschlags 7 und außerhalb des Schwenkbereichs desselben sind Bogenhochhalter 12 angeordnet, die an Armen 13 befestigt sind und mit diesen um eine zur Welle 9 parallele Achse am Ausleger 1 schwenkbar gelagert sind. An den Bogenhochhaltern 12 ist ein Eingriffschutz 14 angebracht. Der Eingriffschutz 14 besteht aus einem leicht abgekanteten Blech, das einen offenen Bereich zwischen dem Bogenanschlag 7 und einem im Abstand davon angeordneten Verkleidungselement 15 des Auslegers 1 über die gesamte Breite des Formats abdeckt und dadurch einen Eingriff in die Bewegungsbahn des Kettenfördersystems 2 von der Zugangsseite des Auslegers 1 her unmöglich macht.On the side of the sheet stop facing away from the sheet stack 4 7 and outside the swivel range of the same Bow support 12 arranged, which is attached to arms 13 are and with them about an axis parallel to the shaft 9 on Boom 1 are pivotally mounted. On the bow brackets 12, an intrusion protection 14 is attached. Protection against intrusion 14 consists of a slightly folded sheet, an open area between the bow stop 7 and a cladding element 15 arranged at a distance therefrom of the boom 1 covers the entire width of the format and thereby an intervention in the path of movement of the chain conveyor system 2 from the access side of the boom 1 makes impossible.

Für die Entnahme eines Probebogens wird, wie in Figur 2 gezeigt, zunächst der Bogenhochhalter 12 zusammen mit dem Eingriffschutz 14 in den Bogenablageweg über dem Bogenstapel 4 geschwenkt. Hierdurch werden die in der Folgezeit einlaufenden Folgebogen 17 hochgehalten, so daß der vordere Randbereich eines Probebogens 16 freiliegt. Anschließend wird durch eine Drehung der Welle 9 um etwa 90° der Bogenanschlag 7 von dem Bogenstapel 4 abgestellt. Der Probebogen 16 ist nun frei zugänglich und kann an seinem vorderen Rand mit der Hand gegriffen und aus dem Bogenstapel 4 herausgezogen werden. Bei diesem Vorgang ist der Eingriffsbereich durch den Eingriffschutz 14 zum Kettenfördersystem 2 hin vollständig abgedeckt. Nach der Probebogenentnahme wird der Bogenanschlag 7 in die Anschlagposition zurückgefahren und anschließend der Bogenhochhalter 12 zurückgezogen, wobei die hochgehaltenen Folgebogen 16 auf den Bogenstapel 4 herunterfallen.For the removal of a sample sheet, as in FIG. 2 shown, first the bow support 12 together with the Tamper protection 14 in the sheet storage path above the sheet stack 4 swiveled. This will result in the following period incoming sequence sheet 17 held up so that the front Edge area of a test sheet 16 is exposed. Subsequently is the arc stop by rotating the shaft 9 by about 90 ° 7 parked from the sheet stack 4. The test sheet 16 is now freely accessible and can be on its front edge gripped by hand and pulled out of the sheet stack 4 become. In this process is the area of intervention through the intervention protection 14 to the chain conveyor system 2 completely covered. After the sample sheet has been taken, the Bow stop 7 moved back to the stop position and then the sheet holder 12 is withdrawn, whereby the subsequent sheets 16 held up fall onto the sheet stack 4.

Bei dem in Figur 3 gezeigten Ausführungsbeispiel ist in einem Abstand von der vorderen Stapelfläche 8 des Bogenstapels 4 ein Hilfsanschlag 20 angeordnet, der als zweiarmiger Hebel ausgebildet ist und auf einer an einem Träger 21 befestigten zur Welle 9 des Bogenanschlags 7 parallelen Achse 22 schwenkbar gelagert ist. In seiner in der Zeichnung dargestellten Anschlagposition I ist der Hilfsanschlag 20 mit seiner Anschlagfläche 23 in einem geeigneten Abstand parallel zur vorderen Stapelfläche 8 ausgerichtet, wobei der kürzere Hebelarm 201 des Hilfsanschlags 20 von einer nicht dargestellten Schenkelfeder gegen einen Anschlag 24 am Träger 21 gedrückt wird. Gegenüber den Fingern des Bogenanschlags 7 ist der Hilfsanschlag 20 in axialer Richtung versetzt, so daß der Bogenanschlag 7 an dem Hilfsanschlag 20 vorbeigeschwenkt werden kann.In the embodiment shown in Figure 3 is in a distance from the front stacking surface 8 of the sheet stack 4 an auxiliary stop 20 arranged as a two-armed Lever is formed and attached to a bracket 21 axis parallel to the shaft 9 of the bow stop 7 22 is pivotally mounted. In his illustrated in the drawing Stop position I is the auxiliary stop 20 with its stop surface 23 parallel at a suitable distance aligned with the front stacking surface 8, the shorter lever arm 201 of the auxiliary stop 20 from one not shown leg spring against a stop 24 on the carrier 21 is pressed. Opposite the fingers of the bow stop 7 the auxiliary stop 20 is offset in the axial direction, so that the sheet stop 7 on the auxiliary stop 20th can be swung past.

Radial außerhalb des Schwenkbereichs des Bogenanschlags 7 befindet sich ein kombinierter Bogenhochhalter und Eingriffschutz 19, der aus einem gebogenen, sich über die Formatbreite hinaus erstreckenden Blech 25 besteht, dessen außerhalb des Formats liegende Enden an Armen 13 befestigt sind. Die Arme 13 sind mittels Zapfen 26 im Ausleger um eine zur Welle 9 parallele Achse schwenkbar gelagert sind. An dem Hilfsanschlag 20 weist das Blech 25 eine Öffnung 27 auf, durch die der kurze Hebelarm 201 des Hilfsanschlags 20 hindurchragt. Der Träger 21 ist ebenfalls in einer Öffnung des Blechs 25 angeordnet, die sich in Umfangsrichtung erstreckt, um eine Schwenkbewegung des Blechs 25 zu ermöglichen.Radially outside the swivel range of the bow stop 7 there is a combined bow support and tamper protection 19, which consists of a curved, over the format width also extending sheet 25, the out of format ends attached to arms 13 are. The arms 13 are by means of pins 26 in the boom an axis parallel to the shaft 9 are pivotally mounted. The sheet 25 has an opening 27 on the auxiliary stop 20 through which the short lever arm 201 of the auxiliary stop 20 protrudes through. The carrier 21 is also in an opening of the sheet 25 arranged in the circumferential direction extends to allow a pivoting movement of the plate 25.

Bei normaler Bogenauslage befinden sich der Bogenanschlag 7, der Hilfsanschlag 20 und das Blech 25 in den in der Zeichnung mit durchgezogenen Linien dargestellten Positionen. Soll ein Probebogen entnommen werden, so wird zunächst der Bogenanschlag 7 durch Drehen der Welle 9 von dem Bogenstapel 4 abgestellt und an dem Hilfsanschlag 20 vorbei in die gestrichelt dargestellte Position II geschwenkt. In dieser Stellung des Bogenanschlags 7 ist der Raum zwischen dem Bogenstapel 4 und dem Hilfsanschlag 20 frei, so daß ein nun folgender und mit ausreichendem Bewegungsimpuls zugeführter Probebogen 16 sich über die vordere Stapelkante 7 hinausbewegt und mit seiner Vorderkante an den Hilfsanschlag 20 anstößt. Bedingt durch die Position II des Bogenanschlags 7 ist hierbei aus Sicherheitsgründen zunächst ein Zugriff auf den oder die ankommenden Probebogen 16 nicht möglich, denn der Bogenanschlag 7 sperrt mit seinen in geringem Abstand parallel nebeneinander angeordneten Fingern in Verbindung mit dem Blech 25 in dieser Stellung den Eingriffsbereich für die Probebogenentnahme ab. Nach dem Ablegen eines Probebogens 16 oder mehrerer wird das Blech 25 mit Hilfe eines nicht näher dargestellten Antriebs in die gestrichelt dargestellte Entnahmeposition III über den Bogenstapel 4 geschwenkt, wodurch die Folgebogen 17 von dem Blech 25 hochgehalten werden. Bei dem Schwenkvorgang des Blechs 25 wird außerdem durch den an den kürzeren Hebelarm 201 des Hilfsanschlags 20 anstoßenden Rand der Öffnung 27 der Hilfsanschlag 20 um seine Achse 22 gedreht und in die gestrichelt dargestellte Entnahmeposition III gebracht, in der er mit seinem kurzen Hebelarm 201 an der konkaven Seite des Blechs 25 anliegt und dadurch gegen die Kraft der Schenkelfeder hochgehalten wird. Gleichzeitig wird der Bogenanschlag 7 durch Drehen der Welle 9 aus der Position II in die Entnahmeposition III bewegt. In der Entnahmeposition III ist somit der überstehende Rand des Probebogens 16 frei zugänglich, wobei der Eingriffsbereich nach oben durch das Blech 25 und nach unten durch den Bogenanschlag 7 geschützt ist, so daß es durch eine falsche Bewegung bei der Entnahme des Probebogens 16 mit der Hand nicht zu einer Verletzung kommen kann. Zusätzlich wird die Entnahme durch den definierten Überstand des Probebogens 16 erleichtert.With a normal sheet delivery, the sheet stop is located 7, the auxiliary stop 20 and the sheet 25 in the in Positions shown with solid lines. If a sample sheet is to be taken, the first step is the bow stop 7 by rotating the shaft 9 of the Sheet stack 4 parked and past the auxiliary stop 20 pivoted into position II shown in dashed lines. In this position of the bow stop 7 is the space between the sheet stack 4 and the auxiliary stop 20 free, so that a now the following and supplied with sufficient movement impulse Trial sheet 16 over the front stacking edge 7 moved out and with its front edge to the auxiliary stop 20 triggers. Due to position II of the arch stop 7 is initially a for security reasons Access to the incoming sample sheet 16 or not possible, because the bow stop 7 locks with its in fingers spaced parallel to each other in connection with the sheet 25 in this position Area of intervention for the sample sheet removal. After this Placing a sample sheet 16 or more becomes the sheet 25 with the help of a drive not shown in the removal position III shown in dashed lines over the Sheet stack 4 pivoted, whereby the subsequent sheet 17 of the Sheet 25 are held up. With the swiveling of the Sheet metal 25 is also due to the shorter lever arm 201 of the auxiliary stop 20 abutting edge of the opening 27 the auxiliary stop 20 rotated about its axis 22 and into the Removed position III shown in dashed lines, in which he with his short lever arm 201 on the concave side of the sheet 25 is applied and thereby against the force of Leg spring is held up. At the same time the Bow stop 7 by rotating the shaft 9 from the position II moved to the removal position III. In the removal position III is thus the protruding edge of the test sheet 16 freely accessible, the engagement area up through the sheet 25 and down through the Bow stop 7 is protected so that it is wrong Movement when the sample sheet 16 is removed by hand cannot be injured. In addition, the Removal through the defined protrusion of the sample sheet 16 facilitated.
