Definitions
- the above invention relates to a method with which it is possible to automatically move printing cylinder receiving carriages into the printing elements.
- rotary printing presses consist of a series of printing elements which are arranged at a distance from one another and are equipped with known mechanical devices which make it possible to move the paper web to be printed through a large number of printing elements arranged one behind the other.
- Each of these printing elements has a pressure roller in a known manner, which has the task of pressing the paper web against a printing cylinder.
- Each printing cylinder is stored in its own receiving carriage and each receiving carriage has a known doctor device and an ink application device.
- the printing cylinder receiving carriages that are no longer used must be removed from the assigned printing element, and only then is it possible to insert new printing cylinder receiving carriages into the spaces that are provided between the printing elements, and then the receiving carriages with the new cylinders into the Retract printing units in order to start the printing process of the new product after carrying out the previously described processes.
- a device has become known from the prior art, in which a transport device is provided in axis with the printing elements, on which the printing cylinder receiving carriage are arranged to move the carriage from a waiting position into the space between each two printing elements and then to insert the corresponding printing cylinder receiving carriage into the printing element.
- the cylinders are pushed through the individual printing units in order to occupy the subsequent free space between two printing elements and then deposited again on the transport device by a transverse movement.
- This known device has the disadvantage that it is necessary to provide a deep channel in the longitudinal direction of the rotary printing press, which channel is suitable for accommodating the components for the transport device of the printing cylinder receiving carriage.
- a rotary printing press has also become known in which an attempt has been made to reduce the downtimes for exchanging the printing cylinder receiving carriages to reduce the fact that for each printing element there is a double printing cylinder receiving carriage, that is to say a receiving carriage which is designed to receive two printing cylinders, two squeegee devices and two corresponding ink application devices.
- a pressure element can be removed which is equipped with a receiving carriage which is provided with two pressure cylinders.
- the receiving carriage can be moved back and forth relative to the pressure element, but it cannot be moved out of the pressure element.
- the pressure cylinder receiving carriages designed as double carriages are also very heavy, which leads to an undesirable one Sluggishness in the movement of the pickup carriage. If damage occurs in the interior of the known receiving carriage, then this receiving carriage, which is proposed as a double construction, has to be removed from the pressure element in a time-consuming manner in order to enable repair at another location. In a likewise complex manner, a new receiving carriage has to be installed in the pressure element. The entire printing press must be shut down for these run-in or replacement processes, which means a considerable loss of production.
- auxiliary carriages are provided for moving the printing cylinder receiving carriages. These auxiliary carriages can be moved over the entire length of the printing press in a conveyor channel provided over the entire length of the printing press. Additional auxiliary carriages are required to move the pressure cylinder pick-up carriages Longitudinal movement in a specially provided conveyor channel must also perform a lifting movement in the vertical plane.
- the object of the above invention is to avoid the disadvantages of the prior art and to propose a method in which it is possible to dispense with a transport device for the printing cylinder receiving carriage and consequently also with a corresponding receiving channel for this transport device and to create the possibility of with the provision of a limited space between two printing elements to hold a printing cylinder receiving carriage in the waiting position, and thereby to limit the length of the entire rotary printing press to a minimum and at the same time to open up the possibility of exchanging the Printing cylinder pick-up trolleys can be carried out easily and with short times.
- this object is achieved by a method according to the patent claim.
- each printing element 1, 2, 3 is traversed by a web 4 to be printed.
- a printing cylinder receiving carriage A1 is arranged in each printing element 1, 2, 3.
- Each receiving carriage A1 is equipped with a pressure cylinder in a known manner. Furthermore, each carriage A1 has a known doctor device and a known ink application device.
- a pressure roller 5, 6 or 7 is provided in each pressure element 1, 2, 3, which can be raised and lowered and presses the web 4 against the pressure cylinder of the receiving carriage A1.
- Fig. 1 the rotary printing press is shown schematically during the printing process.
- the receiving carriages B1 are then moved along the dash-dot line S, as shown in FIG. 5. As can be seen from FIG. 6, the free spaces which have now formed on the left side of the printing units 1, 2 and 3 are occupied by new receiving carriages B2 which remain in the waiting position.
- the entire carriage group consisting of the pick-up carriages A2 and the pick-up carriages B2 is moved again in the direction of arrow f, that is to say from left to right, whereupon the loading cycle is repeated.
- the inventor proposed that during the process of replacing the printing cylinder receiving carriages, the entire carriage group (consisting of printing cylinder receiving carriages inside the printing units 1, 2 and 3, as well as replacement carriages, which are arranged in the waiting position in front of the printing units 1, 2 and 3) with a pendulum-like shifting movement once to the right and then move it to the left altogether, the inventor noticed that the devices for controlling and moving the receptacles can be extremely simple.
