Definitions

the invention relates to a device for clamping printing plates on the plate cylinder of printing presses, in particular sheetfed offset printing presses, according to the preamble of claim 1.
a printing plate is fastened to the plate cylinder by means of tensioning rails arranged in a cylinder channel and assigned to the printing start and the printing end by first inserting (clamping) the printing start of the printing plate into the corresponding tensioning rail and then also clamping the printing end in the second tensioning rail and then is stretched with force.
tensioning rails arranged in a cylinder channel and assigned to the printing start and the printing end by first inserting (clamping) the printing start of the printing plate into the corresponding tensioning rail and then also clamping the printing end in the second tensioning rail and then is stretched with force.
DE 3 940 795 C2 From DE 3 940 795 C2, DE 3 940 796 C2 and EP 0 431 575 A2 systems for automatic printing plate change are known, in which the removal of an old printing plate and the mounting of a new printing plate from or to the plate cylinder takes place automatically.
these systems In addition to storage and receiving areas for the printing plates, these systems also have transport devices for supplying or removing a new or old printing plate while the plate cylinder is being rotated in the corresponding direction.
the pressure plates are attached by means of clamping rails the plate cylinder, which, as indicated in the individual documents, have remotely operable devices for the appropriate clamping or clamping.
the new printing plates to be supplied have a bevel at the end of the print and this bevel is inserted into a radial gap between two clamping pieces. For clamping and ultimately also for tensioning, these two clamping pieces are then pivoted in an almost azimuthal direction by an eccentric shaft.
the disadvantage here is that the new printing plates to be fed are to be bent at their printing end by a special device. This bending must be done very carefully, as possible. Waviness in the folded area can lead to canting and thus lead to problems when inserting it into the gap of the tensioning rail. Because of the problems to be feared due to ripples, used printing plates with such a system are unlikely to be fed. A folded end of the print is also not easily conveyed by a transport system with a nip.
non-folded printing plates can be used because of the specially designed printing end clamping rails.
the clamping flaps causing the detection have a specially arranged pivot pole, which is known from DE 3 626 936 C1.
a clamping flap causing this allows the printing end of the printing plate to be placed on a lower clamping device, but results in a relatively large pivoting angle of the clamping flap. It is disadvantageous here that such a clamping flap pivoted into the open position protrudes correspondingly far out of the circumference of the circle of the plate cylinder and thus impairs a pressure roller which causes the pressure plate to be placed on it.
DE-GM 6 941 597 describes a tensioning rail of a plate cylinder of printing machines assigned to the printing end of a printing plate known, which consists of two relatively movable clamping pieces through which the printing end of the printing plate can be detected.
This clamping rail consisting of the two clamping pieces, is pivotally mounted for clamping about an axis running parallel to the plate cylinder.
a disadvantage of the device described is that it is not possible to interact with automatic printing plate changing systems.
the object of the present invention is to develop a device for clamping printing plates on the plate cylinder of printing machines according to the preamble of claim 1 in such a way that simple and safe insertion of the printing end of the printing plate into the corresponding tensioning rail is ensured especially when interacting with an automatic printing plate changing system is.
the tensioning rail according to the invention can be swiveled around one of two axes running parallel to the plate cylinder, depending on the swivel position.
the detection area of the tensioning rail which is designed as a gap, thus executes a curved path with two radii of curvature up to a position in which the pressure plate is completely gripped in order to insert the pressure plate.
the pressure plate is then clamped by closing the gap, in that the lower and the upper clamping piece are braced against one another or, in the case of a self-locking clamping device, after the gap has been closed and during a first Pressure plate tensioning phase.
the detection area of the clamping rail is now pivoted about the axis that gives the small pivot radius of the gap. This pivoting movement continues until the necessary tensile force is exerted on the pressure end of the pressure plate.
the gap for the detection of the pressure plate end can thus be pivoted over an overall large distance without one or more spring (s) applying the tension force for the pressure plate having to be excessively overpressed (spring force to be stored by an actuating element).
the tensioning rail according to the invention simplifies the mounting of a new pressure plate considerably, since its trailing end does not have to be inserted into the detection area of the tensioning rail designed as a gap, but rather the pressure end of the pressure plate is detected by the described pivoting movement of the tensioning rail.
the pressure plate attached to the start of the print on the plate cylinder and drawn up according to its length around its circumference must therefore only be laid flat in the area of the print end, so that a secure detection of the trailing end of the pressure plate is then ensured by the subsequent pivoting of the tensioning rail.
the printing end of the printing plate can be applied either by hand or when using the tensioning rail according to the invention in connection with an automatic printing plate changing system by means of a corresponding pressure roller.
the pressure roller with a certain force is applied to the plate cylinder and the plate cylinder is then rotated into a corresponding position.
the swiveling of the tensioning rail ensures that the printing plate is gripped securely.
the force to be used to tension the pressure plate is applied by at least one spring, in particular a compression spring.
spring means such as torsion bars or leaf springs can also be used.
the compression spring which is preferably to be selected, is supported at one end in a cylinder-fixed manner and is articulated at its other end with a corresponding pretension via a pull rod on the upper clamping piece. The articulation and the set preload is such that the tensioning rail is pivoted into an open position.
an actuating shaft is arranged in the cylinder channel and runs parallel to the cylinder axis, which is articulated, for example, via a lever arm and a bracket in the manner of a toggle lever mechanism on the upper clamping piece of the tensioning rail.
the tensioning rail arranged in the cylinder channel is divided into several identical sections and each section is pivotably mounted in the manner described and is provided with a spring means for tensioning.
the application of the clamping force is thus carried out in sections at the end of the printing plate, so that automatic alignment is possible especially in the case of a large printing plate format and, for example, register corrections can also be made by changing the position of a front clamping rail.
the spring means assigned to the individual sections can be used for Register corrections are preloaded accordingly. As a result, an asymmetrical or unilateral warping of the pressure plate in the circumferential direction can be deliberately caused.
the section-by-section subdivision of the tensioning rail results in a modular system, so that plate cylinders must be equipped with a corresponding number of sections in accordance with the printing plate format to be provided.
the 3B format for example, seven identical sections of the tensioning rail can be provided.
An actuating shaft and also a clamping shaft are provided for the sections of the tensioning rail of the same design, the latter being guided through all the sections.
the common actuating shaft acts on a corresponding number of lever arms and tabs on the individual sections.
the rotation of the common clamping shaft and the actuating shaft can be carried out by motors arranged in the plate cylinder, for example compressed air motors.
one or more actuating devices are fixedly arranged on the frame of the printing press, which act on the shafts in a certain positioning of the plate cylinder via couplings or lever arms.
the tensioning rail denoted overall by 1, consists of an upper and a lower clamping piece 2, 3, which are arranged in the cylinder channel 4 so as to be pivotable by the plate cylinder 5.
the upper clamping piece 2 has the profile shown.
the lower clamping piece 3 essentially has a U-shaped profile and is connected, for example, to the upper clamping piece 2 with one or more retaining screws 6, so that the lower clamping piece 3 is displaceable in the plane of the drawing relative to the upper clamping piece 2.
This mobility is achieved, for example, by the spherical head of the retaining screw 6 and corresponding dimensioning of bores in the clamping pieces 2, 3 (indicated by dashed lines in FIG. 1).
the upper outer flank of the lower clamping piece 3 and a straight surface of the upper clamping piece 2 form the clamping surfaces 7, 8 of the gap 9 for the pressure end of the printing plate 10 to be detected. Due to the described displaceability of the lower clamping piece 3 relative to the upper clamping piece 2, one in the Gap 9 inserted pressure plate 10 with the clamping surfaces 7, 8 are detected or clamped.
the upper clamping piece 2 has a prismatic edge 11 in a side facing the bottom of the cylinder channel 4 and approximately diametrically to the position of the corresponding clamping surface 7.
This edge 11 is assigned a stop 12 which is arranged in a cylinder-fixed manner on the bottom of cylinder channel 4 and against which the edge 11 of the upper clamping piece 2 bears in the position according to FIG. 1.
the upper clamping piece 2 with the lower clamping piece 3 can thus be pivoted about the pivot axis A formed by the edge 11 and the cylinder-fixed stop 12.
the swivel radius from the gap 9 corresponds approximately to the distance between the clamping surface 7 and the edge 11.
the length of the tensioning rail 1 is divided into several sections 13 of the same type, each having a section as shown in FIGS. 1 to 3.
one end of a pull rod 14 is articulated on the upper clamping piece 2, which is oriented in the direction of the cylinder body and at the other end, for example via a plate 15 with a corresponding thread, engages a prestressed compression spring 16 (FIG. 1).
Compression spring 16 extends essentially coaxially to the tie rod 14 and is supported with its other end on a base plate 17 which is attached, for example by means of screws, to the bottom of cylinder channel 4 and has the stop 12.
the prestressing force of compression spring 16 can be adjustable via threads on tie rod 14 and plate 15.
a support surface 18 is arranged, by means of which the upper clamping piece 2 is supported by the force of the compression spring 16 in the position shown in FIG. 1 on the base plate 17. This position is exactly the one in which the tensioning rail 1 is fully open and thus defined by the angle of the support surface 18 with respect to the clamping surface 7.
actuating shaft 19 mounted in cylinder channel 4, which, as shown in FIGS. 1 to 4, is articulated to clamping pieces 2 in each section 13 via a lever arm 20 and bracket 21. This articulation takes place here, as can be seen in particular in FIG. 4, via two webs 2.1 attached to the rear of the upper clamping piece 2, which have the edge 11 of the pivot axis A and the support surface 18 according to FIGS. 1-3.
actuating shaft 19 By rotating the actuating shaft 19, each upper clamping piece 2 of a section 13 and thus the tensioning rail 1 as a whole can be pivoted against the force of the compression spring 16.
each section 13 of the tensioning rail 1 is assigned a bearing plate 22 on both sides, which is shown again in a reduced form in FIG. 5.
Each bearing plate 22 has on both sides a stop 23 forming the pivot axis B in the form of a cylindrical pin 23.1, about which the upper clamping piece 2 can be pivoted against the force of the compression spring 16.
the bearing plates 22 at the format limits have only one pin 23.1 on the side on which a section 13 of the tensioning rail 1 is also provided.
the upper clamping piece 2 has a contour 24 approximately in its central profile area, which corresponds in dimension to that of pins 23.1 (FIGS. 1-3).
the contour 24 is attached to both ends of its section 13 in the upper clamping piece 2 such that when the upper clamping piece 2 is pivoted about the pivot axis A of the edge 11 or stop 12 it bears against the pin 23 of the bearing plates 22 after a certain pivoting angle. With continued rotation of the actuating shaft 19, the upper clamping piece 2 is thus pivoted about an axis of the pins 23.1.
the edge 11 lifts off the stop 12; the swivel radius of gap 9 now essentially corresponds to the distance between the clamping surface 7 and the axis of pin 23.1 and is smaller than that of the previous swivel angle.
the tensioning rail 1 can be pivoted via the actuating shaft 19 into a position according to FIG. 2. The end position of this swivel angle results either from a mechanical stop or the extended position of the toggle mechanism 20, 21.
the lower clamping piece 3 can be displaced with respect to the upper clamping piece 2 via a clamping shaft 25 and can be adjusted with force to the clamping surface 7.
Clamping shaft 25 has a cylindrical profile with a flattened side and is inserted in a correspondingly profiled recess 25.1 in a lower part of the upper clamping piece 2.
a strip 26 with a trapezoidal profile which has one or more bores for the passage of the retaining screws 6 (not shown).
the upper surface of the strip 26 acts with a roller 27 and an inner surface of the lower clamping piece 3 together like an inclined plane.
the lower clamping piece 3 can also perform a movement in the direction of the clamping surfaces 7, 8.
a pull exerted on the lower clamping piece 3 in the detection area 9 thus causes the bar 26 and the roller 27 to generate or increase the clamping force.
the detection area 9 is opened, for which purpose the lower clamping piece 3 can in turn be reset to a starting position by spring means (not shown).
All sections 13 of the tensioning rail 1 or the upper clamping pieces 2 are actuated by a clamping shaft 25 which is in particular continuous (FIG. 4).
the pivot shaft 25 is able to compensate for any deviations from the pivoting positions of the individual sections 13 by corresponding deformations in the longitudinal direction.
the clamping shaft 25 can also be provided between the sections 13 in the region of the bearing plates 22 with compensating couplings.
the bearing plates 22 provided between the individual sections 13 have two bores 28, 29 in addition to the journals 23, bore 28 serving to carry out the clamping shaft 25 and being dimensioned in accordance with the possible pivot position and bore 29 serving, for example, to support the actuating shaft 19 in sections ( 4 and 5).
two adjacent sections 13 of the tensioning rail 1 are each connected in the area above the bearing plates 22 with a threaded spindle 31, which is formed in the central area, for example as a hexagon, and has a right and a right end at both ends Has left-hand thread.
the printing plate 10 is completely pulled up on the plate cylinder 5 by its rotation and the printing end of the printing plate 10 is placed, for example, by a pressure roller 30 (dashed in FIG. 1) in the region of the tensioning rail 1 pivoted into the fully open position.
the lower clamping piece 3 On a side facing the pressure plate 10, the lower clamping piece 3 additionally has a support surface 9.1 in the form of a bevelled continuation of the clamping surface 8.
FIG. 6 corresponds to the fully open position
FIG. 8 to the fully advanced position
FIG. 7 to the position in which the pivot axes A, B are changed.
the upper clamping piece 2 is supported in this version with an edge 11 formed on its underside in turn on a stop 12, which is on the one hand by a cylindrical surface, for example a base plate 17 and on the other hand by the outer circumference of the actuating shaft 19 or one or more thereon located Bearing 32 (eg needle bearing) is formed.
This stop 12 formed by a cylinder-fixed surface and the outer circumference of the actuating shaft 19 or of the bearing or bearings 32 thus forms the pivot axis A.
a prestressed spring is preferably attached to the upper clamping piece 2 in this way (with a section-wise subdivision of the tensioning rail 1 each spring) is articulated, through which the upper clamping piece 2 is pulled with a support surface 18 in contact with a cylinder-fixed surface, for example the base plate 17.
the upper clamping piece 2 thus assumes the position shown in FIG. 6, which corresponds to the fully open position of the tensioning rail 1.
the spring means and their articulation points are not shown;
the upper clamping piece 2 has the profile shown in FIGS. 6, 7, 8, which, following the edge 11, has a contour 24 which corresponds to the outer circumference of the actuating shaft 19 or the bearing 32 thereon.
the upper clamping piece 2 that is to say the tensioning rail 1
the tensioning rail 1 is pivoted about the pivot axis A from the fully open position according to FIG. 6 by rotating the actuating shaft 19, for example via a driving arm
the contour according to FIG. 7 is created 24 to the outer periphery of the actuating shaft 19 or the bearing (s) 32.
the pivoting of the tensioning rail 1 now takes place in such a way that the upper clamping piece 2 is pivoted about the actuating shaft 19, which now forms the pivot axis B.
the edge 11 of the upper clamping piece 2 thus lifts off the stop 12 of the pivot axis A.
the tensioning rail 1 is now, from the position shown in FIG. 7, pivoted about the pivot axis B of the actuating shaft 19 into the fully advanced position shown in FIG. 8, by a mechanical not shown or a path limitation the actuating shaft 19 can be defined.
the lower clamping piece 3, as shown in FIGS. 6, 7, 8, has an L-shaped profile and, for example, is mounted opposite the upper clamping piece 2 in a manner similar to that described above.
a clamping shaft 25 here also has a flattened side and is supported in the manner of an inclined plane on a surface of the upper clamping piece 2. The clamping shaft 25 opens or closes the gap 9 formed by the clamping surfaces 7, 8 between the upper and lower clamping pieces 2, 3 for gripping / releasing the pressure plate 10.
the actuating shaft 19 can cause the tensioning rail 1 to swivel forward via a driving arm, which acts on a rear part of the upper clamping piece 2, for example in the region of the support surface 18.
the actuating shaft 19 can in turn be articulated on the upper clamping piece 2 via at least one lever arm and at least one bracket (not shown).
the swivel axis A is designed in the manner of a cutting joint and the swivel axis B is designed as a swivel joint, which is to be regarded as a preferred embodiment of the general inventive concept.
