Gegenstand der Erfindung ist eine Vorrichtung, um selbsttätig eine Druckpresse auszurücken in dem Falle, daß der Bogen an den Vordermarken der Presse im richtigen Augenblick noch nicht oder schief anliegt. Bei vorliegender Vorrichtung wird - das Ausrücken der Presse durch einen Finger bewirkt, dessen Vorderende dicht über der Vorderkante des Bogens liegt, wenn dieserThe invention relates to a device for automatically operating a printing press to move out in the event that the sheet at the front lays of the press in the correct Moment not yet or is wrong. With the present device - the disengagement of the press by a finger causes the front end of which is just above the front edge of the sheet when this

ίο in richtiger Lage an den Vordermarken anliegt; in dieser Lage wird der Bogen durch eine senkrecht auf- und abgehende Platte angehoben , welche unterhalb der Bogenbahn liegt, so daß die obere Fläche des Bogens gegen den Finger gebracht wird; dadurch wird der Finger aus der Stellung herausgebracht, in welcher er die Ausrückung bewirken könnte. Wenn dagegen die Vorderkante des Bogens nicht in richtiger Lage zuίο is in the correct position on the front lays; in this position the sheet is lifted by a plate that rises and falls vertically which lies beneath the sheet path so that the upper surface of the sheet is brought against the finger; through this the finger is brought out of the position in which it causes the disengagement could. If, on the other hand, the leading edge of the sheet is not in the correct position

den Vorderanschlägen sich befindet, so bleibt der Finger in Ruhelage, trotzdem die Platte in die Höhe geht, wodurch dann die Ausrückung erfolgt. Der Finger kann in Wirkung treten, selbst wenn die Presse dünnes Papier bedruckt oder Papier, dessen Kante leicht umgebogen oder zerknüllt ist. Der Finger kann auch dicht an der Fluchtlinie der Vordermarken angebracht werden, ohne Gefahr, daß er zu dicht an die Oberfläche.the front stops is located, the finger remains in the rest position, regardless of the plate goes up, which then causes the disengagement. The finger can be in effect even when the press is printing on thin paper or paper with a slightly bent or crumpled edge. Of the Finger can also be placed close to the alignment of the front lays without Risk of it being too close to the surface.

In den Zeichnungen veranschaulicht Fig. 1 eine Oberansicht einer Seite des Anlegetisches einer Druckpresse, die mit der Ausrückvorrichtung versehen ist. Fig. 2 zeigt einen Schnitt nach der Linie 2-2 der Fig. I. Fig. 3 zeigt einen Einzelteil, nämlich die Ausrückvorrichtung und einen Teil der Vorrichtung zur Kontrolle seiner Bewegung. Fig. 4, 5 und 6 zeigen Einzelteile, und Fig. 7 zeigt eine Vorderansicht des Kontrollfingers und das Ende der Platte, die mit dem Kontrollfinger zusammen arbeitet.In the drawings, FIG. 1 illustrates Fig. 3 is a top view of one side of the feed table of a printing press associated with the release mechanism is provided. Fig. 2 shows a section along the line 2-2 of Fig. I. Fig. 3 shows an individual part, namely the release device and part of the device for controlling its movement. Figs. 4, 5 and 6 show individual parts, and Fig. 7 shows a front view of the control finger and the end of the plate that shares the control finger working together.

In den Zeichnungen bezeichnet A¹ eine der Vordermarken der Presse, an die die Bogen durch geeignete Bogenzuführungsvorrichtungen heranbefördert werden, so daß sie im richtigen Augenblick von den Greifern der Druckpresse A ergriffen werden. Die nach den Vordermarken rückenden Bogen gelangen über einen Tisch B, welcher am Vorderende des Anlegetisches der Presse angebracht' ist.In the drawings, A ¹ denotes one of the front lays of the press, to which the sheets are conveyed by suitable sheet feed devices so that they are gripped by the grippers of the printing press A at the right moment. The sheets moving towards the front lays pass over a table B, which is attached to the front end of the feed table of the press.

Die Vorrichtung zum Ausrücken der Maschine besteht aus einem Arm C, der an einer Büchse C¹ sitzt, welche drehbar auf der Stange C² ist. Letztere liegt quer über dem. Anlegetisch B. Der Arm C ist mittels einer Stange C³ mit einer entsprechenden. Ausrückvorrichtung, z. B. einer elektrischen Schaltvorrichtung, Riemen- oder Kupplungsausrückvorrichtung verbunden. Zum Ausrücken der Maschine wird der Arm C durch eine Klinke C⁴ bewegt, welche in den Zahnkranz C⁵ am Arm C eingreift. Die Klinke ist an einem lose auf der Stange C² sitzenden und von irgend einem sich bewegenden Teile der Presse in Drehung gesetzten Arm C⁶ (Fig. 3) drehbar. Während des normalen Ganges der Druckpresse wird die Klinke C⁴ von einerThe device for disengaging the machine consists of an arm C which ^{is seated on a sleeve C 1} which is rotatable on the rod C ² . The latter lies across the. Feed table B. The arm C is by means of a rod C ³ with a corresponding. Release device, e.g. B. an electrical switching device, belt or clutch release device connected. To disengage the machine, the arm C is moved by a pawl C ⁴ , which engages in the ring gear C ⁵ on the arm C. ^{The pawl is rotatable on an arm C 6} (Fig. 3) sitting loosely on the rod C ² and set in rotation by some moving part of the press. During the normal running of the printing press, the pawl C ^{4 is} of a

Claims

Guide C ⁶¹ , which is provided with a nose C ⁷ , carried by a pin C ^{8 of} the pawl comes against this nose, so that the pawl is held out of engagement with the tooth segment C ⁵ . The guide C ⁶¹ sits loosely on the sleeve C ⁹ on the rod C ² . The sleeve C ⁹ is provided with .einem arm C ¹⁰ (Fig. I) which carries ^{one end of the crossbar C 11;} the other end of the rod is in

ίο an arm C ¹⁰ attached to the opposite side of the press, which sits ^{at the other end of the rod C 2.} The weight of the arms C ¹⁰ and the rod C ¹¹ keep the guide C ⁶¹ in contact with the pin C ⁸ and thus the pawl C ⁴ out of engagement with the ring gear C ^{5 as it} swings back and forth.

As long as the sheets are brought up in the right way to the front lays, the guide C ⁶¹ and the associated parts to swing freely around the rod C ^'2, and therefore they move uniformly with the reciprocating Hind reciprocating pawl C ^1, so that the pawl does not mesh with the ring gear C ⁵ . But if a sheet is not in the correct position on the front lays, while the pawl is moving forward, the guide C ⁶¹ and the parts connected to it are taxed by a stop D.

retained, which falls into a groove C ^{12 of} the cross ^{rod C 11.}

The stop D is seated on a lever D \ which is rotatably seated on the arm D ^2. The latter is adjustably mounted on the sleeve C ¹ , and the stop D is disengaged from the groove C ¹² when the finger D ^{3 is} raised, which is attached to the lever D ¹ by screws d and slots d ^l (Fig. 5 ) is attached and its front end D ^{4 is} above the arched path immediately behind the front stops. The finger D ³ gets its movement, when a sheet is in the correct position on the front ^{lays, by the plate £> 5} , which lies below the sheet path and at its front end has a cutout Z) ⁶² (Fig. 4), which is below of the front end of the finger D ³ lies. The sheet is guided up to the front end of the finger D ³ by a guide plate D ⁶ which can be rotated around the arm D ^2. The plate D ^e is held by the finger D ³ by a bolt D ¹ provided with a nut D ^{8 playing} on the plate D ⁶ in a slot d ^{2 of} the finger D ³ .

The plate D ⁵ is attached to the oscillating shaft D ⁹ , which lifts the plate shortly after the leading edge of a properly fed sheet abuts the front fence, and immediately after the plate D ⁵ is raised, the pawl C ⁴ moves forward.

If, for some reason, a sheet is not fed at the right time so that it could be gripped by the grippers of the press, or in the event that the sheet is inserted at an angle and not so that its leading edge is exactly against the front stops , the plate D ⁵ only lifts the plate Z) ⁶ when it goes indie height, without lifting the finger D ³ in the air. In this case, the stop D remains in the groove C ¹² , thereby preventing the free movement of the rod C ¹¹ and the associated guide C ⁶¹ ; the pawl C ⁴ slides down from this, as a result engages in the toothed segment C ⁵ and sets the release mechanism in motion.

Godfather nt-A ν saying:
