Definitions

the invention relates to a forme cylinder with slot-shaped pressure plate insertion according to the preamble of claim 1.
a supply device for compressed air on a rotatable cylinder of a printing press via a cylinder journal has become known.
Compressed air is first supplied to one or more radially arranged bores, which are connected to one or more axially extending bores, via a supply which is fixed to the frame and has an outlet which can be lowered temporarily to the surface or in the vicinity of the cylinder journal.
the axially extending bores are connected to radially extending bores which open into plug-in means or openings for the compressed air outlet.
Forme cylinders for offset roll rotary printing presses with slot-shaped printing plate insertion have been known for a long time.
the beginning of the printing plate is bent with an acute and the end of the printing plate with an obtuse opening angle.
the end of the pressure plate with the acute opening angle is first seen in an acute-angled hook-in edge, seen in cross section hooked in, whereby the length of the hooking edge corresponds at least to the pressure plate width.
the hooking edge formed from a hooking radius with an inclined contact surface for the beginning of the printing plate, forms, together with a contact surface for the printing plate end folding, which is parallel to it, and a base surface adjoining it, the slot-shaped printing plate end entry.
the distance between the opposing contact surfaces is slightly larger than twice the printing plate thickness.
This very narrow slot for receiving the two printing plate ends and the full seating of the printing plate on the circumference of the forme cylinder means that the printing plate end bend cannot be pulled out of the slot so easily in order to change the printing plate. That's why you use suction cups that you put on the area around the pressure plate end on the pressure plate and then pull the end out of the slot with more or less damage.
the invention has for its object to provide a device on a forme cylinder of a rotary printing press, with which a folded end of a printing plate without tools is easily lifted from an insertion slot for receiving printing plate bends at least as far in the slot that the printing plate end convenient by an operator or Automat can be pulled out of the slot and thus the affected end of the pressure plate can be lifted from the cylinder circumference.
a forme cylinder 1 of a rotary printing press On a forme cylinder 1 of a rotary printing press is one, two bent ends having printing plate z. B. placed an offset printing plate.
the fold for the beginning of the printing plate has an acute angle
the fold for the end of the printing plate has an obtuse angle Beta.
Both ends come to rest in an insertion gap 2 in the forme cylinder 1 when the printing plate is placed on top.
Such an insertion gap 2 is well known and has been described in detail in the introduction to the description, so that a repetition is omitted for reasons of simplification.
At least the pressure plate end with the bend with an obtuse-angled opening angle Beta - hereinafter referred to as "obtuse-angled bend" - is pressed into an insertion gap 2 and holds there until the pressure plate is to be replaced.
a number of lifting devices 4 are provided for lifting the pressure plate end in the area 3 before the bend of the pressure plate end. They act out of the jacket and act on an underside of the printing plate in such a way that the end of the printing plate is raised in front of its folding line and thus pulls the end of the printing plate out of the insertion gap at least until this end can be easily detached from the forme cylinder 1.
This lifting device 4 can consist of various means. So z. B. a lifting and lowering bar can be provided. However, a plurality of nozzles 6 can also be provided in a particularly advantageous manner for the discharge of compressed air.
the controlled compressed air occurs e.g. B. from all the nozzles 6 at the same time and lifts the pressure plate end in the vicinity parallel to the folding line of the folded pressure plate end to the extent that at least the side edges can then be gripped.
the end of the pressure plate is lifted up so far that the bend of the end of the pressure plate has completely left the insertion gap 2.
the nozzles 6, which end with the lateral surface of the forme cylinder 1, ie do not protrude beyond them, are fed with compressed air via first radial bores 7.
the bores 7 begin in an axially extending storage chamber 8 for the compressed air, which by means of several second radiler Bores 9 is connected to an axial bore 11.
This axial bore 11 is connected to a radial bore, not shown, in a shaft journal.
the clocked supply of compressed air via z. B. a device according to DE 42 03 550 A1 from a compressed air source.
