Definitions
- the invention relates to a printing press according to the preamble of claim 1.
- blowing air units In order to be able to observe the printed images behind the individual printing units, especially when printing, it is necessary for printing presses to temporarily remove the blowing air units from their working positions, since these are positioned when they are placed close to a roller carrying the printing material, such as an impression cylinder , obscure the view of the substrate. Furthermore, the blowing air units, on which and in which fine ink dust and other dirt can settle during printing, must be able to be removed for cleaning.
- the blowing air unit can be moved away from the impression cylinder in an essentially radial direction and can be adjusted again by guiding the blowing air unit over slides or carriages in guides fixed to the frame.
- the blower device is provided with coupling pieces which can be coupled to the lines, one of which is accommodated in a side frame.
- the connecting pieces of the blast air unit and the supply air and exhaust air stubs of the air supply and discharge lines have sealing rings made of elastomeric material for the sealing connection.
- the object of the invention is therefore to provide a printing machine of the type described in the introduction, in which a very tight connection can still be established between the inlet and outlet openings of the blown air unit and the supply air and exhaust air connections even after a long period of time.
- the blowing air unit can be moved " in two mutually independent directions during the insertion process. These movement possibilities make it possible to bring the blowing air unit close to the printing material guided on the guide roller without touching the seals on the lines or nozzles. Independent of this movement the blowing air unit also move in such a way that the seals attached to the blowing air unit or its openings can be pressed onto the seals of the supply air and exhaust air nozzles without the seals rubbing against each other. Of course, the movements can also be reversed to remove the blowing air unit from the Separate the supply air and exhaust air connections and be able to move the blast air unit away from the guide roller for the purpose of observing the printing material.
- the blowing air unit can initially be moved in one direction such that the inlet opening with the supply air connector and the outlet opening with the exhaust air connector are each on the same escape axes, and if the blowing air unit is then in a second direction, which is parallel to the escape axes runs, is movable.
- Such directions of movement make it possible for the blowing air unit to be first shifted in the direction of the printing material and then to be moved in the second direction, so that a sealing connection is established between the blowing air unit and the supply air and exhaust air connections, without stressing the seals with shear forces.
- both directions of movement do not need to be orthogonal to one another.
- the blowing air unit can be moved in the second direction, which runs parallel to the escape axes, by means of applying and / or transmitting a force. Since the seals are made of elastomeric material, they exert a restoring force when pressed together. This ' force must be overcome when moving the blown air unit, which is why means are provided for applying and / or transmitting a force. If the seals are separated from one another, frequently adhering forces prevent a complete separation, so that forces also have to be applied. Means for applying a force can gain the force, for example, through energy conversion, such as in an electric motor. However, magnetic forces are also to be mentioned that can be used for the stated purpose. For example, means for transmitting a force can be piston-cylinder units which provide the pressure of compressed air directly as a mechanical force.
- the force provided by the means for applying and / or transmitting a force can be introduced into means for supporting.
- means for supporting can be, for example, threaded rods which, due to the force provided, perform a linear movement relative to the spindle nut via spindle nuts.
- the means for supporting is connected, at least during the displacement of the blowing air unit, to the second direction, which runs parallel to the escape axes, with a component that provides a counterforce.
- the means for supporting thus causes the movement of the blowing air unit relative to the supply air and exhaust air connections. If the blowing air unit is in the working position, the connection can remain in place so that the connection between the seals cannot unintentionally detach.
- the means for applying and / or transmitting the force, the means for supporting and also the components providing the counterforce can be attached to the side frame, to the blown air unit and / or to the supply air and exhaust air connections.
- the means for applying and / or transmitting a force are a tensioning lever and / or a resilient element.
- the blowing air unit can then be brought into its working position by means of the clamping lever.
- the applied force can be used to tension a resilient element, for example a compression spring, the energy of which can later be used to reliably separate the connection of the blown air unit to the supply and exhaust air connections.
- the means for supporting consist of at least one bolt aligned essentially parallel to the escape axes.
- the bolt is advantageously mounted displaceably on the blown air unit.
- the tensioning lever, the resilient element and the bolt can form a functional unit.
- the bolt can be pushed away from the perspective of the blown air unit using the tensioning lever.
- the bolt can then be retracted using the opposing force of the spring. Since the counterforce acts on the bolt at the same time, the blowing air unit can be moved by operating the clamping lever.
- the component providing a counterforce is a centering piece attached to a side frame and / or a hook.
- the bolt can carry a washer on its end facing the side frame.
- a centering piece has the advantage that the blowing air unit does not inadvertently perform a movement in the first, independent direction of movement during the movement in the second direction, which is parallel to the escape axes.
- the means for supporting can be determined after the working position of the blowing air unit has been reached. This determination may for example take place via the clamping lever, which can be provided for this purpose with a recess'.
- FIG. 1 blowing air unit of a printing machine according to the invention in the
- Fig. 1 shows a section of a printing press according to the invention.
- This section represents the drying station 1, which comprises the blown air unit 2.
- handles 3 are attached to the blown air unit 2.
- the guide rails 5 are fastened to the side frames 7, 8 by means of stud bolts 6.
- the side frame 8 is provided with an opening 9 through which the supply air connector 10 and the exhaust connector 11 extend. Both nozzles 10, 11 are attached to the side frame 8 in a manner not shown.
- the supply air connector 10 is via a supply air hose 12 connected to a blown air supply.
- the exhaust air enriched with solvent is discharged via exhaust air connection 11 and an exhaust air hose 13 attached to it.
- the connecting pieces 10, 11 are connected to a counter-holding plate. Seals 26 are placed on these ends of the connecting pieces.
- a quick release unit is fastened to the side of the blown air unit 2 facing the side frame 7.
- the bolt 21 is slidably mounted.
- a compression spring acts on the bolt 21 in such a way that it always experiences a force in the direction of the lever 18.
- the lever 18 is also connected to the guide 16 via a web 17, so that the range of motion of the bolt 21 is limited.
- the restoring force of the compression spring, in conjunction with the hook 25, causes a relative movement of the blown air unit in the direction of the side frame 7, the range of motion being dimensioned via the web 17 in such a way that the blown air unit 2 no longer touches the seals 26.
- the lever 18 is equipped with an eccentric 20. If the lever 18 is now folded over by the handle 19 by the operating personnel, the eccentric 20 presses the bolt 21 in the direction of the side frame 7.
- the centering piece 23 fastened to the bolt 21 fits into a bore in the receptacle 24.
- the disc 22 lies after a short Idle distance on the receptacle 24, so that the bolt 21 can no longer move relative to the side frame 7.
- the blowing air unit 2 moves in the direction of the side frame 8, so that the blowing air unit 2 finally reaches its working position.
