Description
Pneumatischer Bogenanleger mit Trenn- und Fördersaugern und Bläserfuß zum Trennen des obersten Bogens von einem Stapel Die Erfindung betrifft einen pneumatischen Bogenanleger mit Trenn- und Fördersauger und Bläserfuß zum Trennen des obersten Bogens von einem Stapel, wobei der Bogen einzeln oder in einer Bogenbahn weitergefördert wird Es ist bekannt, daß die mit den traditionellen Antriebsmitteln, wie Rädern, Exzentern, Gestängen, Wellen usf., bewegten Bogentrenn-, Albhebe- und Fördermittel an den pneumatischen Bogenanlegern nicht mehr ausreichen, da jahre Tätigkeit nicht erlaubt, den erheblich gesteigerten Geschwindigkeiten und Leistungen der Druckmaschinen mit gleichwertiger Trenn-und Förderarbeit zu folgen. Pneumatic sheet feeder with separating and conveying suction cups and blower foot for separating the top sheet from a stack. The invention relates to a pneumatic one Sheet feeder with separator and conveyor sucker and blower foot for separating the top one Sheet from a stack, the sheet being conveyed further individually or in a sheet path It is known that those with traditional drive means, such as wheels, Eccentrics, rods, shafts, etc., moving sheet separating, lifting and conveying means on the pneumatic sheet feeders are no longer sufficient, as years of activity are not sufficient allows the significantly increased speeds and performance of the printing machines with equivalent separation and promotion work to be followed.
Auch die mit mehr oder weniger aufwendigem Gestänge von einer Magnetspule betriebenen Arbeitsmittel reichen nicht zu einer einwandfreien und sicheren Vereinzelung und Zuführung von Bogen bei einer schnellaufenden Druckmaschine aus. Bei den schnellen Bewegungen der hin- und hergehenden Trennmittel schlagen sich die Teile außerdem schnell aus. Even those with a more or less complex linkage from a magnetic coil operated work equipment is not sufficient for a perfect and safe isolation and feeding sheets from a high-speed printing press. With the fast ones Movements of the reciprocating release agent hit the parts as well off quickly.
Diese Nachteile werden durch den Gegenstand der Erfindung beseitigt, und zwar dadurch, daß die Bogentrenn- und Fördersauger und der Bläserfuß die Spulenkerne taktmäßig und zeitgerecht stromdurchflossener Wicklungen oder Spulen bilden. These disadvantages are eliminated by the subject matter of the invention, namely by the fact that the sheet separators and conveyors and the blower foot the bobbin cores Form clockwise and timely current-carrying windings or coils.
Ein Beispiel zum Erfindungsgegenstand ist in den Zeichnungen dargestellt. Es stellt dar Fig. 1 einen Aufriß zu den Trennmitteln, den angesaugten Bogen fortführend und Fig. 2 einen Aufriß zu den Trennmitteln in Arbeitsbereitschaft. An example of the subject matter of the invention is shown in the drawings. It shows Fig. 1 an elevation of the separating means, continuing the sucked sheet and FIG. 2 is an elevation of the separating means in readiness for operation.
Auf einem Träger 1, der einen sogenannten Sangkopf danstellt, sind in bekannter Weise die Trenn- bzw. On a carrier 1, which is a so-called Sangkopf, are in a known way the separation or
Fördersauger 2 und 3 und auch der Bläserfuß 4 angeordnet. Sie sind auf die Bogengröße 5 eines in den Bogenanleger eingebrachten Stapels 6 auf dem Saugkopf ein- und feststellbar.Conveyor suction cups 2 and 3 and also the blower foot 4 are arranged. they are to the sheet size 5 of a stack 6 placed in the sheet feeder on the suction head adjustable and lockable.
Jede dieser Bogentrenn- und Fördervorrichtungen hat eine Wicklung bzw. Spule 7, 8, Rtaerhaltlen, die in der Bewegungsrichtung um die Achse konzentrisch angeordnet ist, so daß diese Vorrichtungen elektromagnetisch gesenkt oder gehoben werden, wenn durch ihre Spulen Strom geschickt wird. Each of these sheet separating and conveying devices has a winding or coil 7, 8, Rtaerhaltlen, which are concentric in the direction of movement about the axis is arranged so that these devices are electromagnetically lowered or raised when current is sent through their coils.
Bei Trenn- und Fördersaugern ist es bekannt, diese mit sogenannten Fall- und Springsaugern 10 auszurüsten, die mit dem angesaugten Bogen r4"gegen die Abwärtsbewegung der Trenn- und Fördersauger hochspringen. Ihre Funktionen sind bekannt, und der Gegenstand ist nur zum besseren Verständnis in die Beschreibung einbezogen worden. In separating and conveyor suction cups, it is known to use so-called Equip drop and jumping suckers 10, which with the sucked sheet r4 "against the Jump up the downward movement of the separating and conveyor suction cups. Their functions are known and the subject is included in the description for better understanding only been.
Bei Stromdurchfluß durch die Spule8 wird der die Stapellage kontrollierende Bläserfuß 4 wie ein Eisenkern in die Spule gezogen, wobei der Bläserfuß mit seiner Leitrolle 11 gegen eine feststehende Leitkurve 12 läuft, die ihn in seiner obersten Stellung aus den Stapelbereich und der hinteren Stapelkante zwingt. When current flows through the coil 8, the one controlling the stacking position becomes Blower foot 4 pulled like an iron core into the coil, with the blower foot with its Guide roller 11 against a fixed guide curve 12 runs that put him in his topmost Forcing position from the stacking area and the rear edge of the stack.
Der Fördersauger- wie auch der bei bestimmten Bogenanlegern als Fördersauger ausgebildete Trennsauger erhalten eine Wicklung oder Spule 13 für eine elektromagnetisch beeinflußte Bewegung in der Bogenfördervorrichtung. In dem gezeigten Beispiel ist diese Spule um den Anschluß-Saugstutzen 14 gelegt worden. The suction cup as well as the one with certain sheet feeders as a suction cup trained suction cups receive a winding or coil 13 for an electromagnetic affected movement in the sheet conveyor. In the example shown is this coil has been placed around the connection suction nozzle 14.
Die Trenn- und Fördervorrichtungen2,3 und der die Lage der Stapeloberfläche kontrollierende Bläserfuß 4 werden in der Richtung zur Stapeloberfläche und Bogenföndervorrichtung zur Aufnahme und Fortführung eines Bogens in Bewegung gesetzt, wenn ihre Spulen bzw. Wicklungen 7, 8 und 13 Strom erhalten, der ihnen taktmäßig und zeitgerecht durch Steuereinrichtungen, die nicht Gegenstand der Erfindung sind, zugeteilt wird. The separating and conveying devices 2,3 and the position of the stacking surface controlling blower foot 4 are directed towards the stacking surface and sheet feeder to pick up and continue a bow when its coils are set in motion or windings 7, 8 and 13 receive current that is clockwise and timely is allocated by control devices which are not the subject of the invention.
In bekannter Weise schließt das Kontaktschräubchen 15 auf dem Blatt 16 den Stromkreis zu einem Hubmotor 17 - zum Nachheben des Stapels mittels der Hebemittel 18, 19 -, wenn der Bläserfuß nicht mehr sich auf die Stapeloberfläche abzustützen vermag, weil diese durch die erfolgte Bogenentnahme zurückgeblieben ist. In a known manner, the contact screw 15 closes on the sheet 16 the circuit to a lifting motor 17 - for lifting the stack by means of the lifting means 18, 19 - when the blower foot is no longer supported on the stack surface is able to, because this is left behind by the removal of the sheet.
