Description

The The invention relates to a system for aligning aggregates, in particular of printing units or folders or reelstands, one Printing machine, in particular a web-fed printing press, after Preamble of claim 1.

A Printing machine has one Variety of aggregates, the construction or during assembly of a Press must be aligned in a printing company. To count these aggregates in a web press, at least one reel changer, several Printing units, at least one turning unit and at least one folder.

The Aggregates of a printing press, such. B. the printing units of a Web press, have two opposite each other Side walls, with the side walls over trusses connected to each other, which is the distance between the opposite sidewalls determine. Setting up a printing unit or other units a printing press in a printing is done after practice under With the help of so-called leveling elements, with each to be aligned Aggregate several leveling elements interact with the help of these the respective unit to be aligned in its vertical position is orientable so that the same horizontally and vertically in the Lot is aligned.

At the Setting up aggregates of a printing machine in a printing house It is still necessary, relatively different units to align with each other, namely such that different units are parallel in a defined direction to the longitudinal axis the printing machine aligned.

To In practice, the alignment of different units takes place relatively to each other in the direction of the printing press longitudinal axis by means of a Druckmaschinen longitudinal axis parallel stretched measuring wire, wherein a distance of highly accurate measuring surfaces of the be aligned aggregates to the measuring wire with the help of so-called gauge blocks is determined. According to the distances thus measured the aggregates of the printing press in their relative position in horizontal Direction over the leveling elements are shifted so that they then exactly aligned with each other. Moving the aggregates in horizontal Direction over the leveling is done with the help of heavy equipment, such. From cranes.

The Alignment of aggregates of a printing press relative to each other over the Measuring wire and the with the measuring wire and with highly accurate measuring surfaces of the Aggregates cooperating final dimensions is expensive. It exists Therefore, a need exists for a system for aligning aggregates Printing machine, which without final dimensions a highly accurate alignment of aggregates relative to each other.

Of these, The present invention is based on the object, a novel system for aligning aggregates of a printing machine, in particular a web-fed printing press.

These Task is accomplished by a system for aligning aggregates Printing machine according to claim 1 solved. According to the invention the measuring wire device has one measuring wire and several with the measuring wire interacting measuring contacts on, in which case if the measuring wire conducts an electrical current and at least one of the measuring contacts touched, a signal can be generated by means of which aggregates in their Relative position are aligned such that the side walls of different Units are aligned in the direction of the measuring wire to each other.

At the inventive system the alignment of aggregates of a printing machine is done relatively to each other using an electric current conducting Measuring wire, which interacts with measuring contacts. On the use of gauge blocks, the with highly accurate measuring surfaces of the Aggregates can cooperate in the present invention be waived. Since the measuring wire no longer has to be reachable for final dimensions, can the same at any height parallel to the printing press longitudinal axis be tense.

preferred Further developments of the invention will become apparent from the dependent claims and the following description. Embodiments of the invention without being limited to this to be closer to the drawing explained. Showing:

1 a schematic plan view of aligned with the system according to the invention alignment bolts;

The The invention relates to a system for aligning aggregates Printing machine when setting up the printing press in a printing house.

following the invention is for described the case that a printing unit of a web-fed printing press to be set up and aligned in a printing company. The invention but is not limited to this rather, you can with the system according to the invention also roll changers, folders and turning units of web presses or printing units, feeders and delivery of sheetfed presses be built and aligned in a printing house.

One System for aligning a z. B. trained as a printing unit Aggregates of a printing press in a printing company has with leveling elements interacting with the aggregate to be aligned, wherein with each aggregate to be aligned preferably a plurality of leveling elements such cooperate, that with the help of the leveling elements to be aligned Aggregate in its vertical position is aligned such that the same is aligned horizontally and vertically in the Lot. such Leveling elements include to the state of the art.

In addition to the leveling elements comprises the system for aligning aggregates a printing machine preferably continue to be aligned with several Aggregates cooperating alignment bolts that are independent of the aggregates to be aligned in their relative position in a printing house be aligned so that when later putting up aggregates one side walls each individual unit to be aligned with alignment bolts aligned, and on the other hand side walls of aligning on alignment bolts different units are aligned.

The Accordingly, with the aggregates cooperating alignment bolts independent of the aggregates in a print shop mountable, so later the Only install aggregates with the help of the alignment bolts Need to become.

The The invention now relates to such details of a system for alignment of aggregates of a printing press, by means of which the aggregates or alignment bolt for the aggregates at least in the direction of the machine axis can be aligned in their relative position such that in the direction of the machine axis successively positioned units of the printing press are aligned. Hereinafter, the invention for described the case that alignment bolts, the later recording serve aggregates of the printing press, with the system according to the invention be aligned in their relative position to each other.

So shows 1 schematizes several alignment bolts 10 , which serve the later recording of aggregates of a printing press, wherein the alignment bolts 10 with the help of a measuring wire 11 a Meßdrahteinrichtung, which is stretched parallel to a longitudinal axis of the printing press, can be aligned relative to each other. The measuring wire 11 acts in the embodiment of 2 and 3 with the alignment pins associated measuring contacts 12 . 13 together, in the embodiment of the 2 . 3 each alignment bolt 10 two measuring contacts 12 . 13 are assigned, which are electrically insulated from each other and between which the measuring wire 11 runs.

The measuring wire 11 is placed under electrical voltage and therefore conducts an electric current, in which case when the measuring wire 11 one of the alignment bolts 10 associated measuring contacts 12 . 13 touched, a signal is generated, by means of which the respective alignment bolts are aligned in their relative position such that side walls of the alignment bolt 10 To be included printing press units in the direction of the measuring wire 11 and thus aligned with each other in the direction of the printing press longitudinal axis.

In the embodiment of 2 and 3 are the one alignment bolts 10 associated measuring contacts 12 . 13 on an insulator 14 attached and over the insulator 14 on the alignment bolt 10 mounted, where, as already mentioned, the insulator 14 the measuring contacts 12 . 13 electrically isolated from each other. Each of the measuring contacts 12 . 13 stands over a ladder 15 respectively. 16 with a signal generating device 17 in contact, when the measuring wire 11 one of the measuring contacts 12 . 13 touches, provides a signal, by means of which the alignment bolts 10 can be aligned relative to each other. Thus, the signal generation device comprises 17 two LEDs 18 respectively. 19 , where the LED 18 then lights up when the measuring wire 11 the measuring contact 12 contacted, and where the LED 19 lights up when the measuring wire 11 the measuring contact 19 contacted.

Then, if the measuring wire 11 one of the measuring contacts 12 . 13 an alignment bolt 10 contacted, it means that the alignment bolt 10 in horizontal direction relative to the measuring wire 11 must be moved so that the measuring wire 11 none of the measuring contacts 12 . 13 of the alignment bolt 10 contacted.

Then, if the measuring wire 11 in the area of each alignment bolt 10 between the measuring contacts 12 . 13 the same is guided so that the measuring wire 11 in the area of no alignment bolt 10 a measuring contact 12 . 13 touched, it means that all alignment bolts 10 are aligned exactly to each other, so later aligned to the alignment bolts aggregates of the printing press in Direction of the measuring wire and therefore aligned exactly in the machine longitudinal axis to each other.

Depending on the required alignment accuracy, there is a distance d between the measuring contacts 12 . 13 between 1 mm and 0.1 mm, preferably the distance d between the measuring contacts 12 . 13 an alignment bolt 0.5 mm, the distance d is precisely adjustable to 0.01 mm. The length l of the measuring wire 11 , which is used to align alignment bolts 10 used in the direction of the printing machine longitudinal axis may be several meters, such. B. a length of z. B. 20 m.

In addition to the in 2 and 3 shown measuring contacts 12 . 13 , with the help of which an orientation of the alignment bolts 10 can take place in the direction of the measuring wire and thus parallel to the printing press longitudinal axis, each alignment bolt can be associated with other measuring contacts to align adjacent units in a direction perpendicular to the Meßdrahtrichtung relative to each other. For this purpose, a gauge is then positioned between corresponding measuring contacts of adjacent units, wherein when the gauge conducts an electric current and touches one of these two measuring contacts, a signal can be generated by means of which a distance between the adjacent units is adjustable perpendicular to the measuring wire.

Although related to 1 to 3 the invention has been described for the case that the measuring contacts are assigned alignment bolts, it is also possible that the measuring contacts are assigned to the units to be aligned, in which case can be dispensed with alignment bolts. However, the use of alignment bolts has the advantage that the alignment bolts can be aligned relative to each other, regardless of the later be aligned to the same aggregates with relatively little effort.
