Definitions

• the invention relates to a device for aligning an elevator on a cylinder of a printing press according to the preamble of claim 1.
• EP 0 678 383 A1 shows a device for changing printing forms, wherein horizontally movable holding elements temporarily fix the printing plate to be placed.
• the holding element has a lateral stop and can be moved in the axial direction by an actuating unit
• EP 1 084 838 A1 discloses a device which serves in one position as a holding device for a pressure plate to be supplied and in a second position as protection. It is designed to be pivotable about a pivot axis in a feed plane and has a lateral guide plate.
• DE 196 20 997 C2 discloses various designs for the arrangement of lateral stops for the axial positioning of a pressure plate.
• the stops themselves can be brought into different positions.
• several stops assigned to a plate interact with plates of different widths by means of step-like offset of the stops.
• the invention has for its object to provide a device for aligning a different number of different width elevators.
• the advantages that can be achieved with the invention are, in particular, that an in axial direction of a cylinder exact feeding of an elevator, for. B. a printing form, is possible without having to provide an (adjustable) stop in or on the cylinder.
• the device is easily accessible, adjustable, can be driven by drive means and can be replaced if required, and in a further development ensures that the printing plate is removed in a safe and precise manner.
• the conditions for an automatic or semi-automatic elevator change are significantly improved.
• Fig. 1 shows the device in a first operating situation
• Fig. 2 shows the device in a second operating situation
• FIG. 3 shows the device in a top view in the operating situation according to FIG. 1
• FIG. 4 shows the device in a top view in the operating situation according to FIG. 2
• a cylinder 01 (Fig. 1), e.g. B. a forme cylinder or transfer cylinder, on its outer surface with an elevator 02 (Fig. 2), z. B. a printing form or a, especially designed as a metal blanket blanket.
• the cylinder 01 z. B. fed via a table of elevator 02 so that a folded end can be inserted into a channel.
• a clamping device 03 can be arranged in the channel.
• the ends can also be held by the shape of the end and channel without a clamping device 03. So that the elevator 02, in particular the printing form, in the axial direction of the cylinder 01 is supplied in the correct position and, if necessary, fixed, a device for guiding 04 or for axially aligning the elevator outside the cylinder is provided.
• the device 04 has a pivot axis S which is essentially parallel to the longitudinal direction of the cylinder and around which at least one stop 06; 07 is pivotable.
• This stop 06; 07 is, for example, pivoted away for an operating situation in which no elevator change is to take place (FIG. 1) and pivoted when an elevator is to be fed in (FIG. 2).
• Over the length of the cylinder 01 which, for. B. essentially the width of four printed pages, for. B. newspaper pages, are z. B. four such stops 06 (one for each of four printing plates 02) arranged on a shaft 11 or pivotable crossbar 11.
• the printing forms are e.g. B. by spring force to the respective lateral stop 06; 07 pressed.
• the device 04 for axial alignment is thus designed such that in a first operating situation a certain number of n stops 06 and in a second operating situation a number of m stops 07 that is different from the number n can be brought or arranged in a feed plane of the elevator 02 are.
• 3 and 4 show this situation using the example of a printing press or a cylinder 01, the length of which is designed for printing from four pages arranged next to one another, in particular newspaper pages.
• four for example one printing page, in particular a newspaper page, with a width
• FIG. 3 shows this situation using the example of a printing press or a cylinder 01, the length of which is designed for printing from four pages arranged next to one another, in particular newspaper pages.
• each of the elevators 02 has a stop 06; 07 assigned to one-sided guidance.
• the elevators are each arranged on the same side of the elevator 02 to be fed in each case, in particular on a left side of a typeface located on the elevator.
• a common stop 06; 07 arranged, which has two stop surfaces facing away from each other, each facing the elevators 02 to be fed.
• the device has three such stops 06, 07 in one operating situation and only one stop 06, 07 in the other operating situation.
• the device can also be designed such that in the second operating situation fewer than n stops 06; 07 can be brought into the feed level, but more than the number m specified above.
• This can be the case, for example, if only part of the length of the cylinder 01 is to be able to be covered with elevators 02 that are wide on two printing sides for printing.
• four stops 06 would correspond to four elevators 02 in the first operating situation, and two single-wide elevators 02 and a double-wide elevator 02 could be fed in the second operating situation if the device in FIG viewed from the left has first or third stop 06 from FIG. 3.
• This is corresponding to the design of even wider cylinders 01 and the above-mentioned design with common stops 06; 07 to transfer.
• the device and the swiveling can be integrated into a fully or semi-automatic plate change.
• the axial position of the stops 06; 07, e.g. B. arranged as thin plates ("wings") on a cross member to be pivoted, for example a square tube, can optionally be individually and / or the entire device 04 can be axially adjustable.
• the device 04 has one of the stops 06; 07 different side on one or more rollers 08, which hold the printing form 02 to be accepted to remove the printing form 02 from the cylinder 01 after corresponding pivoting of the device, so that these are positioned precisely on the table, e.g. B. comes to rest on a stop.
• Another auxiliary device 09 for the winding or removing of the elevator 02 can have one or more rollable rollers.
• stops 06; 07 can in principle also be done in a different way.
• a first set of stops 06 and a second set of stops 07 can be brought into the feed plane independently of one another by linear or pivoting movements.
• individual or groups of stops 06; 07 e.g. B. by means of their own drives in or out of the feed plane.
• all of the stops 06 can be brought into the plane in the first operating situation, while some of these stops 06 can be brought out of the plane in the second operating situation.
• the stops 07 that are effective in the second operating situation then correspond to a subset of the stops 06 Control be controlled accordingly, so that in a selectable operating situation such. B. all stops 06 and in a different operating situation a subset of the stops 06 (as stops 07) are effective.
• the device advantageously has an operating situation in which none of the stops 06; 07 is arranged in the feed plane.
