摘要:
The invention relates to printing presses comprising at least one printing cylinder. In said presses a displaceable inking unit and a printing plate changing device can be alternately placed against the printing cylinder or removed from the latter. The invention is characterised in that the inking unit and the printing plate changing device are coupled together in their displacement by a common drive in such a way that they move in opposite directions towards or away from the printing cylinder and/or that the inking unit and the printing plate changing device are interconnected in a fixed manner. However, if individual drives are provided for the displacement of the inking unit and the printing plate changing device, said drives are coupled together by means of a common controller.

The sheet-fed or web-fed printing machine comprises a main unit (1), at least one mobile carriage (2) adapted to be coupled to the main unit for cooperation therewith during printing operations and to be moved away from the main unit during maintenance operations, a control unit for controlling displacement of said mobile carriage toward and away from said main unit, and an access zone (9, 9') surrounding at least partly the mobile carriage for allowing a human operator to get access to the main unit and mobile carriage, which access zone lies outside of the displacement path (10) of the mobile carriage. The printing machine further comprises detection means (11) for monitoring the access zone and detecting presence of a human operator within the access zone. The control unit is operatively connected to the detection means so as to interrupt or prevent displacement of the mobile carriage in case presence of a human operator is detected within the access zone by the detection means and before the human operator penetrates in the displacement path of the mobile carriage.

A method of controlling a printing unit is disclosed. The printing unit comprising a plurality of printing couple pairs, each printing couple pair comprising a plate cylinder and a blanket cylinder and an inking system associated with each printing couple pair operable to supply ink to printing plates mounted on the plate cylinders of said printing couple pairs. The printing unit also comprises a primary module carrying the printing couple pairs and, a pair of secondary modules carrying the inking systems, the secondary modules being movable relative to the primary module from an operative into a non- operative position in which each secondary module is separated from the primary module. The printing unit further comprises apparatus for loading/unloading printing plates from the plate cylinders of the printing unit and the method includes the step of unloading printing plates from the plate cylinders of the printing unit using said apparatus whilst the secondary modules are moving relative to the primary modules into their non-operative positions.

The invention relates to drives for a printing unit (01) provided with at least one printing group (02, 04) comprising two cylinders (06, 07), and an inking (08) which is associated with the printing group. According to the invention, the two cylinders (06, 07) and the inking system (08) are mechanically rotatably driven by means of a drive train (122, 138), independently from each other and other printing groups (03, 04), the two cylinders at least by a first drive motor (121), and the inking system by a second drive motor (128). The drive train (122) of the printing group cylinders and the drive train (138) of the inking system are respectively embodied as drive modules (122, 138), said drive modules forming pre-assembled modular units that are respectively completely enclosed by housings(152, 153, 154) that are different to the lateral frames (11, 12) of the printing unit (01).
摘要:
Vorrichtung (1) zum Austausch von Farbwannen (7) und Rakelvorrichtungen (6) einer Druckmaschine (9), welche folgende Merkmale umfasst: (a) zumindest eine Aufnahmevorrichtung (4, 4a bis e) für austauschbare Teile der Druckmaschine (9); (b) ein Gestell (3), welches sich beim Austausch der Farbwannen in einer dafür geeigneten Position befindet und (c) welches (3) die zumindest eine Aufnahmevorrichtung (4a bis e) trägt. Als erfinderisch wird insbesondere angesehen: (d) dass die zumindest eine Aufnahmevorrichtung (4a bis e) eine Form aufweist, die zum Tragen zumindest einer Farbwanne (7) und zumindest einer Rakelvorrichtung (6) geeignet ist und (e) dass die zumindest eine Aufnahmevorrichtung vertikal verfahrbar ist.
摘要:
When operating parts, such as a plate cylinder (3), a doctor blade (4), an inking cylinder (5) and an ink trough (6), are to be inserted in a printing machine (13), said operating parts (3, 4, 5,6) are placed temporarily secured to a frame (2) adapted to move on a carriage (1) transversely to the latter's direction of motion. Then, the carriage (1) is placed in position in front of the printing machine (13), the front panel of which has previously been removed. After this, the frame (2) is run partially into the printing machine (13), causing the operating parts (3, 4, 5, 6) to be released from the frame (2), after which means in the printing machine (13) transfer them to their final positions, in which they are held securely in the printing machine (13). When said operating parts (3, 4, 5, 6) are to be removed from the printing machine (13), the procedure is carried out in the reverse sequence.

摘要:
Für Druckmaschinen mit mindestens einem Formzylinder, wobei ein Farbwerk und eine Druckformwechselvorrichtung bewegbar und im Wechsel an den Formzylinder angestellt oder von diesem abgestellt sind, wird vorgeschlagen, entweder das Farbwerk und die Druckformwechselvorrichtung durch einen gemeinsamen Antrieb in ihrer Bewegung derart miteinander zu koppeln, dass sie sich gegenläufig zum oder vom Formzylinder bewegen und/oder das Farbwerk und die Druckformwechselvorrichtung fest miteinander zu verbinden. Sofern dennoch für die Bewegung des Farbwerks und die der Druckformwechselvorrichtung einzelne Antriebe vorgesehen sind, sind diese durch eine gemeinsame Steuerung miteinander gekoppelt.
