The invention relates to cylinders of a printing press with a device associated with the respective cylinder for feeding and / or discharging at least one elevator to and / or from the cylinder according to the preamble of claim 1 or 2.

The DE 100 01 322 A1 relates to a method for automatically feeding printing plates to printing presses. It is disclosed a plate cylinder of a sheet-fed press with only one axis-parallel channel to which suction pads of a conveyor promote a printing plate from a disk magazine. DE 100 01 322 A1 has no relation to the problem of conveying printing plates of different lengths from the plate magazine to the plate cylinder or in the opposite direction. Also found in the DE 100 01 322 A1 No indication as to which position the suction grippers act on with respect to the respective length of the pressure plate with a force promoting this pressure plate.

The DE 41 40 413 C2 relates to a device for changing printing plates in offset printing machines. There are plate cylinder of a sheet-fed press with only one axis-parallel channel disclosed, to each of which a respective plate cylinder associated conveyor promote a printing plate from a respective disk magazine. The respective conveyors each have conveyor belts on which rests the respective pressure plate to be conveyed. The conveyor belts are provided with holes which are distributed uniformly over the length of the conveyor belt, wherein a resting on the conveyor belts pressure plate for their local contact pressure through a through the holes of the sucked in each conveyor belt by acting vacuum. In the respective disk magazine printing plates of different lengths are storable, wherein the length of the disk magazine corresponds to approximately half the length of the largest pressure plate to be used. To support a printing plate which is longer than the length of the disk magazine, a support frame which can be pulled out in the context of the disk magazine is provided. Due to the storage capacity of different lengths of printing plates, the same disc magazine is indeed suitable for plate cylinder different circumference, but there DE 41 40 413 C2 no indication to promote the same plate cylinder from the same plate magazine optional printing plates of different lengths, because on the respective plate cylinder is due to its only one channel at its invariable extent only one pressure plate of a certain length mountable.

By the DE 101 23 882 A1 It is known to operate only one axis-parallel channel plate cylinder a sheet-fed press with a trained in a normal format printing plate or alternatively with a printing plate with a shorter format than the normal format.

By the DE 43 42 359 C1 a magazine for the automatic printing plate change is known, wherein the magazine accommodates a plurality of printing plates to be supplied to a plate cylinder, wherein for each provided in the magazine pressure plate, a switchable holding device is provided, all provided in the magazine printing plates are vertically adjusted in cascade-like arrangement in the magazine and with their front edge are placed on the switchable holding device. After an actuation of the holding device, this allows the pressure plate supported by it to fall with the leading edge onto a curved conveying surface, wherein the conveying surface allows the pressure plate to slide to a pair of transport rollers, the transport rollers, after their gripping of the printing plate, conveying them to the plate cylinder. The in the DE 43 42 359 C1 described device has the disadvantage that they by their vertically aligned magazine the Blocked access to the printing unit and thus considerably complicates maintenance and cleaning work to be carried out on the printing unit. Due to the cascade-shaped arrangement of the printing plates, a very long sliding path up to the transport rollers is produced for the printing plate set up on the highest arranged holding device along the conveying surface, which the printing plate has to drive back after actuation of the holding device solely by gravity. One of the flexible pressure plate impressed by the conveying surface curvature counteracts a resulting from the elasticity of the pressure plate restoring moment, which increases the friction between the pressure plate and the conveying surface, the friction naturally inhibits as an energy-absorbing resistance in turn, the sliding movement of the pressure plate on the long conveying surface, so that there is a risk that the pressure plate gets stuck in the magazine as a result of consumption of their drive energy or jamming and thus their leading edge does not reliably reach the transport rollers and as a result can not be reliably supplied to the forme cylinder either.

By the DE 43 27 013 C1 a printing plate cassette for a magazine is known, wherein the cassette accommodates a plurality of printing plates and the printing plates by means of a disk removal device are pulled out of the cassette, wherein spacers fanned the printing plates as an aid to their removal in the removal area, wherein the top pressure plate of a stack of Printing plates with folded at their trailing end Einhänbringeln priority is supplied to a plate cylinder. There is the disadvantage that the printing plates stored in the magazine are spaced apart from one another only in their removal area by the fan-shaped spacer elements. Accordingly, the printing plates to be fed to the cylinder are not stored entirely without contact surfaces in spaced-apart memory positions, so that there is a risk of damage to their surface, in particular when the printing plates are removed from the magazine. Also, it is possible to supply only the uppermost pressure plate in the magazine.

By the DE 42 39 895 A1 a feeding device for the automatic intake of flexible printing plates is known, wherein also in a more or less inclined with respect to the horizontal stack stacked pressure plate by their front area detecting separating and feed rollers associated with a form cylinder printing cylinder, an intermediate cylinder or a transfer drum of a sheet-fed press can be supplied, wherein at least the forme cylinder, the pressure cylinder and the intermediate cylinder each having a gripper system for gripping the non-folded end of the supplied pressure plate. With the separation and feed rollers of this feeder only printing plates without a folded suspension hook at its trailing end from the magazine can be conveyed. When separating the printing plates there is also the risk of damage to their surface.

By the DE 39 40 795 A1 For example, a method and apparatus for automatically feeding a printing plate to a plate cylinder or for discharging a plate cylinder of a rotary printing machine are known. The method of automatically feeding a printing plate to a plate cylinder of a rotary printing press, the plate cylinder including means for clamping and clamping the printing plate, provides that the printing plate is placed in a storage chamber of a printing plate feeding device that rotates the plate cylinder to a printing plate feeding position and the printing plate is fed by means of a number of transport rollers of a clamping device of the plate cylinder. The method of automatically discharging a printing plate from a plate cylinder of a rotary printing press, the plate cylinder including means for releasing and releasing the printing plate is characterized in that the plate cylinder rotates forward to a printing plate release position that a clamping flap for detecting a printing plate end is opened the plate cylinder rotated backwards, that opened a clamping flap for detecting a Druckplattenanfangs and that the pressure plate by means of a number of transport rollers of a Storage chamber is fed to a Druckplattenzuführ- or -abführvorrichtung. The device for carrying out the aforementioned method has at least one transport roller designed as a drive roller and a transport roller designed as a pressure roller, wherein the pressure roller can be adjusted to the drive roller.

By the WO 93/04863 A1 a device for automatically changing printing plates is known, wherein a plurality of printing plates are stored in a magazine and wherein an exchange of a printing plate with a forme cylinder takes place only under an inclination of the magazine.

By the patent US 41 78 848 A a device for automatically supplying printing forms to a forme cylinder is known, wherein printing forms are stored with non-folded ends in a feed direction inclined stack and are driven by rollers via a arranged in the feed direction in front of the stack conveyor sequentially fed to the forme cylinder, each of which is located at the bottom located printing form at its leading end with a sucker from the stack. This very long-building device is not suitable for printing forms with folded ends. Moreover, when pulling out of the directly stacked printing forms there is a risk of damaging their printed image pages.

By the WO 2004/085157 A1 An apparatus for storing a cylinder to be fed to a printing machine elevator is known, wherein a holder in a first Operating position holds the elevator in a first storage position, wherein the elevator with a change of the holder in a second operating position detaches from the holder and leaves its first storage position, below the first storage position of this along the length of the supplied elevator vertically spaced, the from Holder dissolved elevator is provided before its supply to the cylinder storing second storage position. An Indian WO 2004/085157 A1 described method for feeding elevators to a cylinder of a printing machine provides that the elevators to be fed to the cylinder are stored lengthwise without mutual contact, wherein elevators to be sequentially fed to the cylinder are stored one above the other in storage positions spaced vertically along their length, at least one the elevators are supplied to the cylinder only after a change from its vertical upper to a vertical lower storage position.

The invention has for its object to provide cylinders of a printing press with a device associated with the respective cylinder for supplying and / or discharging at least one elevator to and / or from the cylinder, wherein the device is capable of elevators different format, in particular different length to supply the cylinder or remove from the cylinder.

The object is achieved by the features of claim 1 or 2.

The advantage achievable with the invention consists, in particular, in the fact that the device is capable of supplying elevators of different format, in particular of different length, to the cylinder of a printing machine or to remove it from the cylinder. To execute different print jobs, elevators of different sizes may be required on a press, e.g. B. simply wide elevators with a simple length can be used, with a single length elevator the circumference of a cylinder z. B. spanned in about half. In the axial direction of the cylinder several, z. B. two, four or six elevators next to each other. For the execution of some print jobs, the use of a so-called panoramic elevator may be desired, with a panoramic elevator z. B. is twice as wide as two on the same cylinder adjacent juxtaposed simply wide elevators. Furthermore, in the circumferential direction of the cylinder several, z. B. two elevators arranged one behind the other. For the execution of some print jobs, the use of at least one elevator can be provided, which completely encompasses the cylinder; An elevator with a double length is then used. An elevator with a double length may have a width directed in the axial direction of the cylinder which is a multiple, e.g. B. corresponds to an even multiple of the width of a single-width elevator. Preferably, an elevator extends with a double length over all in the axial direction of the cylinder adjacent to each other lifts and is thus z. B. at least as wide as two, four or six juxtaposed simply wide elevators. An elevator with a double length can thus have a format that at least the format of z. B. four, eight or twelve single-width elevators each corresponding to a single length, which is accompanied by a significant increase in reliable mass to be conveyed for the large-sized elevator. Due to the equally necessary bending elasticity of a Obviously, any elevator is much more difficult to handle large elevators than small elevators.

It is a further advantage of the solution found that the device is nevertheless compact in size, although it is capable of feeding elevators of different format to the cylinder of a printing machine or to discharge it from the cylinder. In particular, the device does not have a greater length than is required for conveying and storing a lift of a simple length. Moreover, the device builds extremely flat in their height so that they do not hinder the required accessibility to the printing unit of the printing press. The device is also suitable for elevators of different format which are particularly elastic in their respective length, in particular also for those with suspension legs bent at their respective ends.

In addition, there is an advantage that on a cylinder of the printing press several elevators, in particular those with a simple length, can be changed quickly and reliably at the same time or at least in a very rapid sequence. A stored in the device elevator, in particular one with a simple length, due to the operation of a holding element from a vertically upper storage position falls into an underlying storage position from which it can be transported to the cylinder. By the actuation of the holding element of the stored elevator changes in free fall from its vertical upper storage position in the underlying storage position. The actuation of the holding element is preferably carried out with a controllable drive and can thus be made by machine. When changing the storage position of an elevator stored in the magazine remains to be changed in its storage position elevator during the change process in the magazine, the change is triggered by a controllable machine element of the magazine. An elevator to be changed in its storage position is not exposed to the risk that its surface will be damaged when changing.

The thus performed bending of the leading end 03 of the elevator 01 should, however, only be so strong that the suspension leg 13 attached there still rests securely against the lateral surface 07 of the cylinder 06. To support the safe concern of Einhänlegeels 13 on the lateral surface 07 of the cylinder 06 can, for. B. the support member 24 are employed on the elevator 01, whereby the elevator 01 is held with its leading end 03 close to the lateral surface 07 of the cylinder 06.

In particular, an erroneous access to the shaft 44 is obstructed with the guide plate 49 for a printing plate 37 to be removed from the forme cylinder 33, in which at least one new printing plate 37 is provided or at least ready for delivery. Likewise, the attachment of a guide plate 49, which is not shown in FIG. 5 for the sake of clarity, may also be advantageous at the printing forme magazine 38 arranged below the paper web 46 and cooperating with the forme cylinder 31.

Another embodiment of a printing press with printing forme magazines results in conjunction with a printing machine, for. As a multi-color offset printing machine, the printing units preferably in bridge design or a compact design, ie a low in construction height printing machine with eight pressure points, as it is exemplified in FIG. 36, in at least one frame 97 on a foundation 96 are arranged one above the other , A printing material 46, preferably a paper web 46, is in this case fed to the printing press and passed vertically through the printing units. In FIG. 36, for example, four successive printing units in the direction of transport of the paper web 46 are shown, which for the right and left of the paper web 46 each have a transfer cylinder 32; 34 with a form cylinder 31; 33, wherein in a printing unit at the Paper web 46 opposite transfer cylinder 32; 34 roll on each other. The paper web 46 is z.

Each form cylinder 31; 33 is associated with at least one inking 94, the details of which will not be discussed here. Each form cylinder 31; 33 is a printing form magazine 38; 39, each preferably two shafts 41; 42; 43; 44 has. As in the embodiment previously described in connection with FIG. 5, here too each printing form magazine 38; 39, but at least its storage position for a printing form 36 to be stored; 37, in the working position preferably substantially horizontally or only with a slight inclination of less than 15 ° to the forme cylinder 31; 33 aligned. In the working position of the printing form magazine 38; 39 is at least one printing plate 36; 37 between the shafts 41; 42; 43; 44 and the forme cylinder 31; 33 interchangeable, either by a no longer required to execute a print job 36; 37 from the forme cylinder 31; 33 removed and into the shaft 41; Introduced 42 or a new to execute the print job printing plate 36; 37 from the shaft 43; 44 brought out and on the forme cylinder 31; 33 is mounted. The structural features of the printing form magazines 38; 39 may correspond to those of the embodiment described above in connection with FIG. 5 in this embodiment. It is advantageous if the implementation, in particular the completion of a printing form change is monitored by sensors. Likewise, the printing form magazines 38; 39 in conjunction with the form of cylinders 31; 33 controllable such that preferably from a printing press associated control station from selectively a printing plate change can be initiated. Because the printing form magazines 38; 39 during an ongoing production of the printing press can be prepared for a printing plate change, the standstill of the printing units requiring setup time is reduced to an extremely short period of z. B. less than two minutes, preferably less than ninety seconds, for a complete change of all printing plates 36; 37 in this Printing press arranged printing units. Depending on the design of the printing units z. B. ninety-six printing plates 36; 37 at the same time in use. Such a rapid printing plate change even with a larger number of printing plates 36; 37 greatly increases the economics of the press because of its extremely short downtime.

Further details regarding a method and a device for carrying out the method will now be explained by way of example with reference to FIGS. 6 to 35. 6 shows a forme cylinder 33 with two circumferentially offset by 180 ° channels 08 and two along the circumference of successively arranged printing plates 37, wherein the right angle beveled suspension leg 14 at the trailing in the direction of production P of the forme cylinder 33 end 04 each printing plate 37 each of a arranged in the channel 08, by a spring element 22 pressurized holding means 21 is held on a wall 19, wherein the wall 19 extends from a rear edge 17 of the channel 08 opening opening 09 to the channel 08 out, the holding means 21 by the operation of a the spring element 22 counteracting pneumatic actuator 23 can be solved. At the extending from the front edge 16 of the same opening 09 to the channel 08 toward wall 18 of the acute-angled bent suspension arm 13 is applied form-fitting manner at the leading end 03 of the other along the circumference of the forme cylinder 33 arranged printing form 37. For details on the mounting of the printing plates, reference is made to FIG. 2.

Fig. 6 also shows an engageable by pneumatic actuation of the forme cylinder 33 pressure element 24 in the form of a pressure roller 24 or pressure roller 24. Also close to the forme cylinder 33 is a parallel to the axial direction pivotally mounted alignment device 51 arranged with two diametrically laterally on a printing plate 37 acting, wing-shaped stops 52; 53 provided, wherein the alignment device 51 each with one of their stops 52; 53, a printing forme 37 to be mounted during their feeding on the forme cylinder 33 seitenregistermäßig temporarily fixed. The stops 52; 53 z. B. each formed as a lateral guide plate, wherein the stops 52; 53 z. B. on a pivotable traverse, z. B. a square tube are arranged. The stops 52; 53 differ z. B. in their position based on the axial direction of the forme cylinder 33, so that z. B. for a printing plate 37 simple width of the stop 52 and for a printing plate 37 in the panoramic size of the stopper 53 is brought by a corresponding pivoting of the alignment device 51 is used. The stops 52; 53 may be axially adjustable to the forme cylinder 33 for the required width of the printing plate 37.

FIG. 6 also shows further details of the printing forme magazine 39. The embodiment shown in FIGS. 6 to 35 is based on a variant for the printing forme magazine 39, in which an upper shaft 44 for providing a printing forme 37 to be mounted on the forme cylinder 33 as an independent structural unit independently of a lower shaft 42 for receiving a from Form cylinder 33 removed print form 37 is operable. Both shafts 42; 44 can be used as individually and independently usable and thus independently functional units. This application is of interest if z. B. only the feed of the forme cylinder 33 is to be automated with new printing plates 37, whereas the decrease of used printing plates 37 is performed by an operator. If both shafts 42; 44 are formed in the printing forme magazine 39, results in a fully automatic printing form changer. Both shafts 42; 44 each have all necessary for storing and conveying of printing plates 37 devices and are preferably constructed very compact. In particular, they have despite their capacity of at least two printing plates 37 a low overall height. The height is z. B. less than 150 mm, preferably less than 100 mm.

In the embodiment shown in FIGS. 6 to 35, the shaft 44 is arranged horizontally and aligned tangentially to the. Thereby, the gravity FG exerted on the printing plate 37 becomes supportive of functions described below used in the best possible way. In the shaft 44 is a support 54, on which a to be mounted on the forme cylinder 33 first printing plate 37 with its folded Einhänbringeln 13; 14 can be set up or stored. A stored on the pad 54 printing plate 37 with a simple length L1 is there z. B. with its entire extended length L; L1 on. The pad 54 is preferably not the entire surface, but in the form of parallel strips 54 or slides 54 formed. The suspension leg 14 at the trailing end 04 of the first printing plate 37 is located in the shaft 44 on the side remote from the forme cylinder 33 on a preferably vertical stop 56, the stop 56 of a conveyor 57 linear and parallel to the support 54 in the direction of opening o39 the printing forme magazine 39 is movable in order to convey this first printing forme 37 out of the shaft 44 by a translatory movement and preferably without deformation until the suspension leg 13 can reach the slot-shaped opening 09 of the forme cylinder 33 at the leading end 03 of this first printing forme 37. The stopper 56 thus serves in the slot 44 for the first printing plate 37 as an abutment position and at the same time has the function of a slider 56. If this first printing plate 37 has at the trailing leg 14 at its trailing end 04 at least one register punching, the stop 56 z. B. advantageously also as a perpendicular to the support 54 standing, connected to the conveyor 57 register pin 56 may be formed so that with the application of the first printing plate 37 on the stop 56 for them a Vorregisterung takes place with respect to their side register. The conveyor 57 is z. B. as a belt drive 57 or as a linear drive 57, preferably as a pneumatic linear actuator 57, in particular as a rodless, double-acting linear actuator 57 is formed.

In the shaft 44 is a holder 58, in particular printing form holder 58 for holding at least a second on the forme cylinder 33 to be mounted printing plate 37. As shown in Fig. 13, the second printing plate 37 from the printing form holder 58 above the support 54, ie at a distance a54 above the edition 54 z. B. held by that the printing form holder 58, for example, on the side facing away from the forme cylinder 33 has a parallel to the support 54 movable piston 59 or slider 59, at the end of a holding element 61, z. B. L-shaped angle 61, is arranged, wherein the second printing plate 37 above the support 54 between the angle 61 of the extended slider 59 and in the region of the opening o39 of the printing forme magazine 39 arranged further holding element 62, z. B. a rigidly arranged stop 62 is clamped. The distance a54 in this case has a value which is preferably between twice and four times the length 114 of the Einhänlegeels 14 at the trailing end 04 of the second printing plate 37. The clamping of the second printing plate 37 takes place in that a clear distance a58 between the angle 61 of the extended slider 59 and the stop 62 is set shorter than the extended length L; L1 of the second printing form 37. The stop 62 in the region of the opening o39 of the printing forme magazine 39 preferably has a bevel 63 on which the suspension leg 13 can be supported on the leading end 03 of the second printing forme 37, the bevel 63 of the stop 62 and the L-shaped angle 61 at which the suspension leg 14 is supported at the trailing end 04 of the second printing plate 37, facing each other. Since the second printing form 37 in particular along its length L; L1 is flexible, it bulges in its clamped between the angle 61 and the stop 62 state. The slider 59 of the printing plate holder 58 is preferably linearly movable parallel to the support 54 and preferably has two stable operating positions, namely a stable operating position in the retracted, the second printing plate 37 releasing state and in the extended, ie the second printing plate 37 clamping state. In a variant of the printing form holder 58, the arrangement of the movable slide 59 and rigid stopper 62 are interchanged, so that the slider 59 is in the region of the opening o39 of the printing forme magazine 39 and the stop 62 on the side remote from the forme cylinder 33 side. As an alternative to the described linear mobility, the angle 61 or the stop 62 can also be arranged to be pivotable about a pivot axis aligned parallel to the width B of the printing forme 37. A between the angle 61 and the stop 62 clamped printing plate 37 is located at its upper or first storage position, while a stored on the pad 54 printing plate 37 assumes a lower, second storage position in this state, the printing plate 37 in the second storage position before their promotion is temporarily stored to form cylinder 33. By an operation, preferably by a remote from, z. B. made by a belonging to the press control panel changes the printing plate 37 within the shaft 44 from its upper, first storage position to its lower, second storage position. Stored in the first storage position and in the second storage position printing plates 37 each having a single length L1 are spaced from each other, for. B. along its length L1 with the distance a54, so they do not touch each other and therefore can not damage.

Another embodiment of the printing plate holder 58, which advantageously allows a particularly low overall height for the shaft 44, provides the second printing forme 37 above the support 54 extending in a single plane in the axial direction of the forme cylinder 33 with at least one retaining element 64 in an upper storage position to hold, with the retaining element 64 z. B. as a guide rail 64, preferably as two mutually parallel guide rails 64, is formed (Figures 7 to 9), wherein the guide rails 64, the second located in the slot 44 printing plate 37 at its two longitudinal sides along at least part of its length L; Hold L1 in the upper storage position. The design of the printing form holder 58 with guide rails 64 assumes that the suspension legs 13; 14 at the ends 03; 04 of the second printing form 37 do not extend over the full width B of the printing plate 37 by not reaching the longitudinal sides of the printing plate 37. The longitudinal sides of the printing plate 37 thus form in the area of the bearing surface 02a of the printing plate 37 a projection with respect to the Einhänbringeln 13; 14. This projection is necessary to make the printing plate 37 in the guide rails 64 feasible. The holding element 64, in particular each guide rail 64, z. B. from a U-shaped, one of the long sides the printing form 37 with a certain game encompassing strap, in which the second printing plate 37 can be inserted from the side remote from the forme cylinder 33 side. The second printing form 37 is thus held by the guide rails 64, preferably in a narrow region of its side, wherein the holder acts in particular as a vertical support and thus as a support against the force acting on the printing plate 37 gravity FG. The guide rails 64 are preferably made of a dimensionally stable material such as metal or plastic.

In order to deposit a second printing forme 37 held on the support 54 by the guide rails 64, at least one of the guide rails 64 is movable in the direction of the width B of the second printing forme 37. Preferably, however, both guide rails 64 along the width B of the second printing plate 37 are movable in opposite directions, so they at least briefly remove each other and their distance from each other such that they no longer support the longitudinal sides of the printing plate 37 vertically, whereby the second printing plate 37 due to at its attacking gravity FG between the guide rails 64 passes through the support 54. If the holding element 64 in a first operating state, the second printing forme 37 z. B. holds by an electric or magnetic force in the upper storage position, the holding member 64 preferably changes remotely from its first operating state to a second operating state, wherein the second operating state causes the holding member 64 that the printing plate 37 and the holding member 64 from each other and the printing forme 37 upon release from the retaining element 64 in the shaft 44 by a free fall and thus alone by the force acting on her gravity FG in the preferably immediately vertically below the upper storage position lying storage position changes. The second printing plate 37 is held in the lower and also in the upper storage position in the shaft 44 at an inclination of less than 15 °, preferably horizontally. At least the guide rails 64 designed as a support bearing for the second printing forme 37 have in their longitudinal extension only this slight inclination or a horizontal course.

A release of the second printing forme 37 from the laterally engaging guide rails 64 is preferably supported by a perpendicular to the bearing surface 02a of the second printing plate 37 stationary stop 67, which is preferably arranged rigidly in the shaft 44, preferably at both longitudinal sides of the second printing plate 37 a such stop 67 is arranged so that during a directed along the width B of the second printing plate 37, opposing movement of the printing plate 37 holding guide rails 64 this printing forme 37 by the stops 67 arranged on both sides in the plane spanned by the support surface 02a of the printing plate 37 level remains. The stops 67 strip the printing plate 37 from the mutually removing guide rails 64 by the printing plate 37 abuts against the stops 67, at the same time the printing plate 37 by the movement of the guide rails 64, the vertical support is withdrawn. The release of the second printing plate 37 is preferably carried out by a z. B. controllable by the press belonging to the control station drive 69, the drive 69 acts on the guide rails 64 and moves them along a travel s68.

If several printing plates 37 are arranged next to each other on the forme cylinder 33 in the axial direction thereof and a plurality of printing plates 37 are arranged next to one another in the shaft 44 in the axial direction of the forme cylinder 33, it is advantageous for the guide rails 64 which act on adjacent second printing plates 37 to be in the printing forme magazine 39 over the Pad 54 in two different planes, that is to be arranged vertically offset from one another, wherein in the axial direction of the forme cylinder 33 successive planes are preferably arranged alternately offset. Due to the staggered arrangement of the planes forming the first storage position of the printing plates 37, a distance a67 between side-by-side in the axial direction of the forme cylinder 33, ie adjacent printing forms 37, can be kept as low as possible. The distance a67 preferably corresponds in its value to a distance that is adjacent to one another on the forme cylinder 33 in its axial direction, ie have adjacently arranged printing plates 37. From in the axial direction of the forme cylinder 33 juxtaposed planes, ie in each case from a first storage position, placed on the pad 54 and thus each placed in their second storage position printing plates 37 can be supplied with the conveyor 57 to the forme cylinder 33 either individually or preferably simultaneously, where the latter procedure for a rapid change of printing plates 37 on the forme cylinder 33 is advantageous. In the axial direction of the forme cylinder 33 stored in different juxtaposed planes printing plates 37 can change simultaneously or at least in rapid succession in their respective second storage position. The form cylinder 33 at the same time jointly supplied printing plates 37 are arranged on the forme cylinder 33 in the axial direction side by side,

In the example shown in FIG. 8, four second printing plates 37 are arranged side by side in each case in their first storage position in the axial direction of the forme cylinder 33, each of these printing plates 37 being held in a guide rail 64 at their respective longitudinal sides. The vertical offset of the printing plates 37 is only a few millimeters, z. B. 4 mm to 6 mm, and corresponds approximately to the overall height of the guide rails 64, preferably their simple to double height. The movement of the guide rails 64 along the width B of the second printing form 37 is z. B. by a linear displacement of the guide rails 64; However, it can also be performed by a pivoting movement of the guide rails 64, wherein the guide rails 64 are pivotable about a pivot axis, wherein the pivot axis parallel to the supported by the guide rails 64 side of the printing plate 37. Thus, a guide rail 64 z. B. attached to at least one pivot arm 68, the z. B. in the plane spanned by the bearing surface 02a of the second printing plate 37 level, which is indicated in Fig. 9 by a directional arrow. The pivot arm 68, one end of which is connected to the guide rail 64 and the other end in the shaft 44 is preferably fixedly mounted, z. B. acting as a laterally on the guide rail 64 Spring element 68, z. B. may be formed as a leaf spring 68, wherein the guide arm 64 connected to the pivot arm 68 by the drive 69, z. B. by a controllable, in particular remotely controllable magnet 69, in a second printing forme 37 holding or one of this printing plate 37 releasing operating position is moved. The travel s68, the movable guide rail 64 performs along the width B of the second printing plate 37, is in the range of a few millimeters, z. B. between 2 mm and 10 mm, preferably 4 mm. Preferably, a stop 67 is also provided in this embodiment, to which the printing plate 37 abuts with its supported by the guide rail 64 side, while the guide rail 64 withdraws the support by their movement of the printing plate 37. Two adjacent pressure plates 37 in the axial direction of the forme cylinder 33 can strike on opposite sides of the same stop 67. During the change from the upper storage position to the lower storage position, the printing forme 37 can also slide vertically downward along one of its sides with the stop 67 so that the printing forme 37 released from the upper storage position reaches the lower storage position in a guided movement. The stopper 67 then has the function of a preferably up to the support 54 reaching side guide for a memory position changing their printing form 37.

In general terms, a method of storing at least two of the same cylinder 06; 31; 33 of a printing press successively discharged elevators 01; 36; 37 the following steps: a) a previously from the cylinder 06; 31; 33 discharged elevator 01; 36; 37 is transported from a first to a second storage position, b) the previously discharged elevator 01; 36; 37 subsequently discharged elevator 01; 36; 37 is at the first storage position of the previously discharged elevator 01; 36; 37 stored, c) the previously discharged elevator 01; 36; 37 in its second storage position and the subsequently discharged elevator 01; 36; 37 in the first storage position of the previously discharged elevator 01; 36; 37 are in a along their length L; L1 orthogonal distance stored, d) the elevators 01; 36; 37 will be in at least largely covering their respective contact surface 02a, preferably at least 80% overlapping or stored in their complete or almost complete coverage. The previously discharged elevator 01; 36; 37 and the subsequently discharged elevator 01; 36; 37 can along their length L; L1 are stored vertically or horizontally spaced apart. Preferably, the previously discharged elevator 01; 36; 37 transported by a linear movement, in particular by a both memory positions directly and directly interconnecting linear movement orthogonal to its support surface 02a or by a movement of its trailing end 04, in its second storage position, which will be explained in more detail below.

It is advantageous, in particular in the shaft 44, for example on the slider 56 for a bearing on the pad 54 first printing form 37 or at the L-shaped angle 61 for a second printing plate 37 to install a code reader 71, each one preferably on the suspension leg 14th at the trailing end 04 of each printing plate 37 mounted coding reads, d. H. detects a feature for identifying a printing form to check in a preferably carried out electronically in a control unit with a provided for the forme cylinder 33, stored in the control unit occupancy plan, if the introduced into the slot 44 printing forms 37 correspond to the allocation plan of the intended printing process and whether for the intended occupancy introduced into the slot 44 printing plates 37 are also in the correct order. Thus, even before the assembly of the printing plates 37 on the forme cylinder 33, a corresponding message, eg. For example, an error message, d. H. a message warning the operator of a faulty installation, generated and z. B. deposited on a printing unit associated control station and displayed there or on the printing unit.

The coding may preferably be in addition to a human-readable code z. B. be designed as a barcode. The code reader 71 is thus preferably in the shaft 44 at its end facing away from the forme cylinder 33 arranged, wherein a reading direction of the code reader 71 either parallel to the length L; L1; L2 of the printing plate 37 or preferably parallel to the width B of the printing plate 37 is directed. In a preferred embodiment, the code reader 71 is preferably arranged with a linear guide movable in or on the shaft 44 or there is a preferably inclined by 45 ° to the width B of the printing plate 37 movable mirror which provides a detection or read signal from one to the printing plate 37 attached code to a arranged on one side of the shaft 44 code reader 71 deflects, so that only a single code reader 71 is required for reading the attached to the stored in the wells 44 printing plates 37 coding. By using only a single code reader 71 for a plurality of stored printing plates 37, significant costs can be saved. In the case of the use of only a single code reader 71, the code reader 71 or the mirror is either parallel to the width B of the printing plate 37, ie in the axial direction of the forme cylinder 33, preferably along several shafts 44 and / or along the pressure forms stacked in one of the shafts 44 37 vertically movable so that the code reader 71 or the mirror detects the coding of stored in different storage positions printing forms 37. Either the code reader 71 or at least one other sensor 91 may be used to monitor and / or to check whether an intended printing plate change has been carried out successfully. Errors such as a double occupancy or a faulty occupancy, ie the assembly of a printing plate 37 at an inaccurate location, are then avoidable, but at least detectable by a preferably deposited on the control station of the printing machine message before a greater damage occurs.

6, a further shaft 42 is shown, which serves the recording of the forme cylinder 33 remote printing plates 37. This slot 42 has a z. B. inclined support 72, which as well as the support 54 in the shaft 44 to provide on the forme cylinder 33 to be mounted printing plates 37 is preferably not formed over the entire surface, but in the form of parallel strips 72 or slides 72, wherein the inclination of Support 72, the shaft 42 preferably widens on the side remote from the forme cylinder 33 side, whereby this slot 42 on the side facing away from the forme cylinder 33 side is more accessible to an operator, which facilitates the removal of stored in the slot 42 printing forms 37. The support 72 in the shaft 42 is z. B. inclined to a horizontal H by an inclination angle δ, wherein the inclination angle δ z. B. between 5 ° and 15 °, preferably about 7 ° can be. In the example shown in Fig. 6, the chute 42 for receiving printing forme 37 removed from the forme cylinder 33 is located below a chute 44 for providing printing forme 37 to be mounted on the forme cylinder 33, which is a preferred, but not mandatory arrangement. The shafts 42; 44 may also be layered in reverse order or may be separate.

A preferred embodiment of the shaft 42 provides that in the shaft 42 in the axial direction of the forme cylinder 33 next to each other at least two printing plates 37 can be stored. This embodiment allows a particularly rapid removal of printing plates 37, in particular when at least two printing plates 37 can be arranged on the forme cylinder 33 in its axial direction, because a plurality of printing plates 37 can be removed simultaneously from the forme cylinder 33. If on the forme cylinder 33 in its axial direction z. B. at least four printing plates 37 can be arranged, it is advantageous for stability reasons, for. B. two shafts 42 in the axial direction of the forme cylinder 33 next to each other. Each defined by the width B of a printing plate 37 storage space in one of these shafts 42 is then formed such that there are at least as many printing plates 37 can be stored as printing plates 37 can be arranged on the forme cylinder 33 along its circumference, wherein the storage of the printing plates 37 at each storage space on top of each other in a stack. It can be provided that in each of the shafts 42 up to ten, but at least up to eight printing plates 37 can be stored so that discharged from the forme cylinder 33 printing plates 37 can be collected in the shafts 42 and the shafts 42 is not necessarily after each change of the printing plates 37 from the operating staff have to be cleared. Regardless of the number of juxtaposed wells 42, the storage locations in the axial direction of the forme cylinder 33 have the same close spacing from each other as the printing formes 37 are arranged on the forme cylinder 33.

At the side facing the forme cylinder 33, the shaft 42 for receiving the forme cylinder 33 remote printing plates 37 at least in the employee on the form cylinder 33 employed operating state near the lateral surface 07 of the forme cylinder 33 arranged guide member 73 which z. B. in the form of a baffle 73, a wedge 73 or a rolling element 73, z. B. a roller 73 is formed and has the task of leading the trailing end 04 of a forme cylinder 33 to be removed from the printing plate 37 into the slot 42. A distance a73 of the guide element 73 from the lateral surface 07 of the forme cylinder 33 is preferably not much greater than the length l14 of the bent-in suspension element 14 at the trailing end 04 of the printing plate 37, in particular the distance a73 of the guide element 73 has a value between the simple and the double Length I14 of Einhänlegeels 14 on (Fig. 6). Since a printing forme 37 to be removed from the forme cylinder 33 touches the guide element 73 with its printed image side, its contact with a rotatably mounted rolling element 73 is gentler on its surface than sliding over a flat rigid wedge 73. This aspect is of particular importance when the printing form 37 should be used again and thus damage to their printed image page by scratches or marks must be avoided. On the guide member 73, a sensor 91 may be mounted, either in contact with the forme cylinder 33 to be removed from the printing plate 37 or advantageously contactless, z. B. inductive, checks whether the suspension leg 14 has actually solved at the trailing end 04 of the forme cylinder 33 to be removed from the printing forme 37 after actuation of the arranged in the channel 08 of the forme cylinder 33 holding means 21. With its test, the sensor 91 sends a signal z. B. to the press belonging to the control room. On the basis of the sensor 91 remote signal is decided whether the process of discharging a From the forme cylinder 33 to be removed printing form 37 can be continued or whether measures to eliminate a fault must be initiated. On the guide member 73, preferably a plurality of sensors 91 are provided in the axial direction of the forme cylinder 33, for. B. four or six, namely in each case at least one sensor 91 for each on the forme cylinder 33 in the axial direction next to each other can be arranged printing form 37th

In a preferred exemplary embodiment, the suspension leg 14 at the trailing end 04 of the printing forme 37 to be removed from the forme cylinder 33 preferably passes on a first ramp 74 spaced from the guide element 73 before reaching the support 72 in the shaft 42, wherein the first ramp 74 initially rises in the direction of the support 72 and, after a summit point 76, drops towards the support 72. The first ramp 74 is preferably rigidly connected to the support 72. As the introduction of the forme cylinder 33 to be removed from the printing forme 37 in the slot 42 hits her suspension leg 14 at the trailing end 04 on a second ramp 77, the edge after its peak point 78, ie, on the side facing away from the forme cylinder 33, preferably abruptly steep falls to rest 72 towards. In the direction in which the printing plate 37 is inserted into the slot 42, a stop 79, which is rigidly connected to the second ramp 77, is arranged a short distance a77 (FIG. 14) behind the summit point 78, to which the suspension leg 14 at the trailing end 04 of the printing plate 37 strikes. The distance a77 has in this case a value of a few millimeters, preferably a value of less than the simple length l14, in particular less than half the length I14 of the folded Einhänbringels 14 at the trailing end 04 of the printing plate 37. If the suspension leg 14 at the trailing end 04 of the printing forme 37 strikes against the stop 79, it preferably engages behind the second ramp 77, in that the suspension leg 14 engages in the space formed by the distance a77. The second ramp 77 and its associated stop 79 are connected by a Conveyor 81 linearly and parallel to the support 72 movable to completely transport the forme cylinder 33 to be removed from the printing plate 37 by a force acting on the trailing end 04 traction in the shaft 42 into it. The conveyor 81, which forms in particular together with the steep flank on the second ramp 77 for the folded suspension leg 14 at the trailing end 04 of the printing plate 37, a printing forme 37 in the slot 42 promoting entrainment is z. B. as a belt drive 81 or as a linear drive 81, preferably as a pneumatic linear drive 81, in particular as a rodless, double-acting linear actuator 81 is formed. Both the first ramp 74 and the second ramp 77 consist z. B. not from full-surface planes, but from several parallel as the tines of a comb arranged guide rails. The second ramp 77 may, for. B. be formed from one or more correspondingly bent metal strip.

On the side facing away from the forme cylinder 33, a lifter 82, in particular a printing form lifter 82 is arranged in the shaft 42, wherein the printing form lifter 82, for example, a preferably perpendicular to the support 72 movable piston 83, at the end of a z. B. L-shaped, in particular U-shaped lifting arm 84 is arranged, wherein the bent suspension leg 14 is set up at the trailing end 04 of the printing plate 37 on the lifting arm 84 or set encompassing. The printing form lifter 82 preferably has two stable operating positions, namely a stable operating position with the piston 83 retracted, in which the lifting arm 84 is below the level defined by the support 72, and another stable operating position with the piston 83 extended, in which the lifting arm 84 the printing forme 37 removed from the forme cylinder 33 lifts from the support 72. The printing form lifter 82 executes a stroke s82 which is greater than the length l14 of the bent-in suspension element 14 at the trailing end 04 of the printing forme 37. Preferably, the stroke s82 has a value between the single length and the double length l14 of the suspension element 14. The printing form lifter 82 lifts thus a printing forme 37 removed from the forme cylinder 33 from a preliminary first storage position to a final second storage position.

Above the printing form lifter 82, in particular above its lifting arm 84, a preferably pivotable about a substantially parallel to the width B of the printing plate 37 extending pivot axis securing element 86 is arranged, for. B. in the form of a strip-like flap 86, whose or the lower edge is located at a distance a86 from the lifting arm 84, wherein the distance a86 is preferably dimensioned smaller than the length of the bent I14 14 hanging 14 at the trailing end 04 of the printing plate 37th In the 6, a directional arrow indicates the pivotability of the securing element 86. The securing element 86 secures a printing form 37 lifted by the printing form lifter 82 against unintentional slippage in the shaft 42 or removal from the shaft 42. Thus, an operator first has to pivot the securing element 86 before the raised printing form 37 can be removed from the shaft 42.

A further exemplary embodiment of assemblies arranged in the shaft 42 is shown in FIGS. 10 to 12. This embodiment provides a preferably rigidly arranged in the central region of the support 72 stop 79, wherein a linearly along the support 72 movable conveyor 81 associated printing form lifter 82 the folded suspension leg 14 at the trailing end 04 of a forme cylinder 33 to be removed printing plate 37 on the Stop 79 raises and the printing forme 37 pulls on its folded suspension leg 14, preferably in its raised state from the printing form lifter 82 state to the side facing away from the forme cylinder 33 end of the shaft 42. The conveyor 81 and the printing form lifter 82 may be positively coupled such that the printing form lifter 82 then lifts the bent suspension leg 14 of the printing plate 37 as soon as the conveying device 81 carries out a movement in the direction away from the forme cylinder 33. Furthermore, between the stopper 79 and the forme cylinder 33 facing the end of the shaft 42, a further printing form lifter 87 is provided which raises the leading end 03 of a form cylinder 33 remote, inserted into the slot 42 printing form 37 so far that another from the forme cylinder 33 to be removed printing plate 37 between the support 72 and the raised printing form 37 in the slot 42 is inserted.

In particular, methods for changing printing plates 37 on a forme cylinder 33 will now be explained with reference to FIGS. 13 to 35. It is assumed that two printing plates 37 are arranged in the upper shaft 44 for providing new printing forms 37 to be mounted on the forme cylinder 33, that two printing plates 37 are placed on the forme cylinder 33 along its circumference and that the lower shaft 42 is for receiving the Shaping cylinder 33 removed printing plates 37 empty, d. H. is free of printing plates 37.

The forme cylinder 33 rotates the opening 09 of a channel 08, in which the suspension leg 14 is held at the trailing end 04 of the forme cylinder 33 to be removed from the printing plate 37 by a holding means 21, in a first position, which is below the guide 42 belonging to the lower guide member 73 is located. The controllable, preferably pneumatically actuable pressure element 24 is set against the forme cylinder 33 (FIG. 13).

The preferably pneumatically actuable actuating means 23 pivots the holding means 21 against the force of a spring element 22, whereby the suspension leg 14 at the trailing end 04 of the printing plate 37 due to its elastic residual stress from the opening 09 snaps and abuts the guide member 73. The employed pressure element 24 secures the printing forme 37 against a further release from the lateral surface 07 of the forme cylinder 33 (FIG. 14).

The forme cylinder 33 rotates counter to its production direction P and pushes the Trailing end 04 of the printing plate 37 into the slot 42. When introducing the printing forme 37 in the slot 42 of the suspension leg 14 slides at the trailing end 04 of this printing plate 37 along the guide member 73 along and then turns on the shaft 42 belonging to the first ramp 74th on. The suspension leg 14 slides up the ramp 74 to above its summit point 76 and then reaches the support 72. While the pressing member 24 is still employed on the forme cylinder 33, the printing plate 37 is further rotated into the shaft 42 by the rotation of the forme cylinder 33 against its production direction P. inserted. In this case, their suspension legs 14 at the trailing end 04 also overcomes the second ramp 77 connected to the conveying device 81 and abuts against the stop 79 connected to the second ramp 77 (FIG. 15).

The pressing element 24 is turned off by the forme cylinder 33. By the impact of Einhänlegeels 14 of the trailing end 04 on the stop 79, the preferably form-fitting at the front edge 16 of the opening 09 hinged folded suspension legs 13 at the leading end 03 of the printing forme 37 from the opening 09. The pressure plate 37 is now with its leading End 03 free on the lateral surface 07 of the forme cylinder 33 on. The forme cylinder 33 has performed less than half a turn from loosening the suspension leg 14 at the trailing end 04 until now. The folded suspension leg 14 at the trailing end 04 has hooked between the second ramp 77 and the stop 79. The conveying device 81 connected to the second ramp 77 and the stop 79 can now completely draw the printing forme 37 into the slot 42 (FIG. 16).

The printing plate 37 is removed from the forme cylinder 33 and is of its length L; L1 to the shaft 42. Your suspension leg 14 at the trailing end 04 is on the summit point 78 of the second ramp 77, while their leading end 03 rests on the summit point 76 of the first ramp 74, whereby at least the suspension leg 13 at the leading end 03 preferably free hangs. The storage of the printing plate 37 in Shaft 42 is thus preferably carried out by a support at two points, namely at the summit points 76; 78 of the two ramps 74; 77 (Figure 17).

The z. B. pneumatically actuated Druckformheber 82 lifts the retracted into the slot 42 printing plate 37 at its trailing end 04 to briefly under the securing element 86, wherein the suspension leg 14 rests on the associated with the printing forme lifter 82 lifting arm 84 (Fig. 18).

While a first to be mounted on the forme cylinder 33 printing forme 37 with its folded Einhänbringeln 13; 14 rests on the support 54 in the upper shaft 44, the forme cylinder 33 continues to rotate counter to its production direction P in a second position until the opening 09, from which the suspension leg 13 at the leading end 03 of the previously removed from the forme cylinder 33 printing plate 37 has been solved has passed a contact point 88 of the pressure element 24 applied to the forme cylinder 33 and the rear edge 17 of the opening 09 in the production direction P of the forme cylinder 33 is at a distance a88 from the contact point 88, the distance a88 being in the range of a few millimeters, preferably is less than 30 mm, and thus corresponds to an arc length of less than a thirtieth part of the circumference of the forme cylinder 33. The first position of the forme cylinder 33 for removing a printing plate 37 arranged thereon is generally not identical with its second position for receiving a new printing forme 37. The pressing element 24 is preferably applied to the forme cylinder 33, while the opening 09 passes the contact point 88 or after passing the contact point 88. The alignment device 51, which is arranged close to the forme cylinder 33, pivots with its previously preferably horizontally oriented diametrical stops 52; 53 preferably by 90 ° in a vertical position, so that a matched to the width B of the forme cylinder 33 to be mounted on the printing plate 37 stop 52; 53 immersed in a plane defined by the support 54 in the slot 44 transport plane for the mounted on the forme cylinder 33 printing plate 37 and immersed on the forme cylinder 33 to be mounted printing plate 37th during its transport from the shaft 44 to the stop 52; 53 page register moderately aligned to the forme cylinder 33 (Fig. 19).

The first printing forme 37 to be mounted on the forme cylinder 33 rests with its suspension leg 14 at its trailing end 04 on the stop 56 connected to a conveying device 57. The conveyor 57 is set in operation, so that the stop 56 in a direction preferably directed tangentially to the forme cylinder 33, the first printing form 37 as far from the shaft 44 moves until its leading end 03 touches the Angestelltenelement 24 attached to the forme cylinder 33 and the this leading end 03 be folded suspension legs 13 between the back in the production direction P of the forme cylinder 33 edge 17 of the opening 09 and the contact point 88 of the pressure element 24 on the forme cylinder 33 (Fig. 20).

The forme cylinder 33 changes its direction of rotation and begins to rotate in its production direction P, whereby the suspension leg 13 set up on the forme cylinder 33 slips into the opening 09 at the leading end 03 of the printing forme 37 and preferably hooks positively onto the front edge 16 of the opening 09 (Fig. 21).

As a result of the further rotation of the forme cylinder 33 in its production direction P, the printing forme 37, which is suspended with its suspension leg 13 in the opening 09, is completely conveyed out of the shaft 44 and mounted on the forme cylinder 33. During winding, the printing forme 37 is rolled onto the forme cylinder 33 by the pressing element 24 placed against the forme cylinder 33. After half a revolution of the forme cylinder 33 in its production direction P, the pressing element 24 presses the folded suspension leg 14 at the trailing end 04 of the printing forme 37 into the opening 09. The retaining means 21 in the channel 08 belonging to this opening 09 has been released and is then inserted into the one Position brought in which it in the Opening 09 inserted suspension leg 14 at the trailing end 04 of the printing plate 37 z. B. fixed by a clamp. The conveyor 57 drives the stop 56 connected to it again into its end position on the side remote from the forme cylinder 33 in the shaft 44 (FIG. 22).

The pressure element 24 is turned off by the forme cylinder 33 and the alignment device 51 pivots with its diametrical stops 52; 53 again preferably in a horizontal position. With the method steps described so far, a change of a first printing plate 37 on the forme cylinder 33 is completed by a used printing plate 37 removed and a new printing plate 37 was mounted. This change of a printing plate 37 can be completed with the described device in a very short time, preferably in less than a minute. The forme cylinder 33 is then ready for production again (FIG. 23).

The change of another, z. B. on the forme cylinder 33 along its circumference arranged second printing form 37 begins with the fact that preferably during the previous ongoing production of an operator, the new second printing plate 37 is inserted into the slot 44. In this case, the second printing form 37 is held by a controllable, preferably pneumatically controllable printing form holder 58 on the support 54 by the printing forme 37 z.
