Description

The invention relates to a device for feeding or discharging a single or double length elevator to or from a cylinder of a printing machine.

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 is sucked to its local contact pressure by a passing through the holes of the respective conveyor belt negative pressure. 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 it blocks the access to the printing unit by their vertically oriented magazine 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 only in their removal area by the fan-shaped Spacers are spaced from each other. 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 is rotated backwards so as to open a clamping flap for detecting a printing plate top and for feeding the printing plate to a printing plate feeding device by means of a number of transport rollers of a storage chamber. 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. In addition, various adjusting means, a pivotally mounted pressure roller for pressing the pressure plate to the plate cylinder and ejection fingers may be provided, wherein the ejection fingers may have tips which are pivotally mounted in the periphery of the plate cylinder. Also, the storage chamber of Druckplattenzuführ- or - be discharged pivoting about a hinge.

The DE 39 40 796 A1 describes a device for automatically changing a printing plate on a plate cylinder of a rotary printing press, the plate cylinder including means for clamping and clamping the printing plate, the printing plate changing device having two storage chambers, so that a plate cylinder dissolved pressure plate can be guided by means of transport rollers in the one storage chamber, while a printing plate stored in the other storage chamber is fed by means of transport rollers to a clamping device of the plate cylinder.

The EP 10 84 839 A1 describes a device for holding and conveying a printing forme. In this case, the device has translational conveying devices which convey a printing forme to be mounted on a forme cylinder or a printing forme to be removed from a forme cylinder. While the device is tilted from a rest position to its operating position for changing a printing form about an axis of rotation, a hook pivots only due to its own weight in the space in which the printing plate is mounted and secures the printing forme at its trailing beveled end against accidental falling out this room.

By the EP 02 14 549 B1 a device for automatically feeding a printing plate to a forme cylinder of a printing press or for discharging a printing plate from a form cylinder is known, wherein the printing plate to be supplied to the forme cylinder is guided by lateral position elements in a desired position, the blanking cylinder, wherein the supply of the pressure plate from a in Essentially horizontal storage position occurs.

By the EP 01 00 779 A1 a device for automatic replacement of printing plates is known, wherein in a disk storage device a plurality of plates to be mounted are suspended from a arranged below the plate cylinder clamping rod and are lifted on the Aufspannstange to the plate cylinder.

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 a device for storing a cylinder to be fed to a printing press elevator is known, wherein a holder holds the elevator in a first operating position in a first storage position, the elevator with a change of the holder in a second operating position detaches from the holder and leaves its first storage position in which, below the first storage position, there is provided a second storage position which is vertically spaced from the latter along the length of the elevator to be supplied and which is released by the holder before it is fed to the cylinder. 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 fed sequentially 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.

By the WO 2005/007405 A2 is a method for mounting and / or detaching a lift with a storage device having a receiving slot for a cylinder to be taken elevator, with a feed chute for a newly wound elevator and with a means of transport, both conveying a new elevator from the feed chute to the cylinder towards as well as conveying a lift to be removed from the cylinder into the receiving shaft in through the same, the two shafts associated transport is made, wherein for supplying a new elevator to the cylinder a supply shaft associated holding means activated on the means of transport and the receiving shaft associated, on the same means of transport holding means is deactivated.

The invention has for its object to provide a device for feeding or discharging a lift with single or double length to or from a cylinder of a printing press.

The object is achieved by the features of claim 1.

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 each elevator are understandable large-sized elevators significantly more difficult to handle than small-sized 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.

B. measured values between 400 mm and 1300 mm and the width B z. B. measured values between 250 mm and 2,400 mm. If a lift 01 when mounted on a cylinder of a printing press state, the circumference of this cylinder spans only about halfway, so will such an elevator 01 here as an elevator 01 denoted by a single length L1. If a lift 01 when mounted on a cylinder of a printing press state, the circumference of this cylinder approximately completely spans, so will such an elevator 01 here as an elevator 01 denoted by a double length L2. At a lift 01 with a simple length L1 are preferred measured values for the length L1 z. B. between 360 mm and 650 mm and for the width B z. B. between 280 mm and 430 mm. An elevator 01 with a double length L2, the maximum dimensions with a length L2 of 1,300 mm and a width of up to 2,400 mm can be achieved.

An elevator 01 with a simple length L1 spanned in its on a cylinder 06 a press mounted state the circumference of this cylinder 06 in that respect only about halfway as the elevator 01 is slightly shorter than the actual dimension of half the circumference of the cylinder 06 , what happens is that the elevator 01 at its ends 03 ; 04 in one on the lateral surface 07 of the cylinder 06 a slot-shaped opening 09 having channel 08 is attached, the elevator 01 by the extent of the slot width S of the opening 09 shorter than the actual dimension of half the circumference of the cylinder 06 , For details about mounting the elevator 01 will be on the 2 with associated description. The same applies to an elevator 01 with a double length L2, which is on the cylinder 06 mounted state the scope of this cylinder 06 likewise only completely encompassed, ie taking into account the slot width S of the opening 09 of the ends 03 ; 04 this elevator 01 holding channel 08 ,

The length L; L1; L2 and the width B spanned surface of the elevator 01 owns a support side, the following bearing surface 02a is called, with which the elevator 01 im on a lateral surface 07 a cylinder 06 arranged state rests ( 2 ). The back of the support surface 02a is a workspace 02b that in the case of the elevator 01 as a printing form 01 is formed, provided with a printed image or at least with a printed image is providable. The elevator 01 has two opposite ends 03 ; 04 preferably in each case in the direction of the support surface 02a angled suspension handles 13 ; 14 , with the ends 03 ; 04 the bearing surface 02a limit and where are the suspension legs 13 ; 14 each preferably completely or at least partially along the width B of the elevator 01 extend. The bearing surface 02a of the elevator 01 is at least along its length L; L1; L2 flexible and with an arrangement of the elevator 01 on the lateral surface 07 of the cylinder 06 whose curvature is customizable ( 2 ). When the printing form 01 on the lateral surface 07 is arranged, the length L runs; L1; L2 of the bearing surface 02a thus in the direction of the circumference of the cylinder 06 whereas the width B of the support surface 02a in the axial direction of the cylinder 06 extends.

Like in the 2 shown are the suspension legs 13 ; 14 of the elevator 01 fastened by means of a holding device, wherein the holding device in a channel 08 is arranged, wherein the channel 08 usually in the axial direction of the cylinder 06 extends. One with the production direction P of the cylinder 06 rectified end 03 of the elevator 01 becomes its leading end 03 whereas the opposite end 04 the trailing end 04 of the elevator 01 is. At least the ends 03 ; 04 of the elevator 01 with the hooked legs molded to it 13 ; 14 consist of a rigid, z. B. metallic material, eg. B. of an aluminum alloy. Usually, the material thickness D of the elevator 01 ( 1 ) or the material thickness D at least from the Einhänbringeln 13 ; 14 a few tenths of a millimeter, z. B. 0.2 mm to 0.4 mm, preferably 0.3 mm. Thus, the elevator exists 01 in the whole or at least at its ends 03 ; 04 made of a dimensionally stable material, so that the ends 03 ; 04 are permanently deformable by a bend against a material-specific resistance.

At least at one end 03 ; 04 of the elevator 01 ( 1 ), but preferably at both ends 03 ; 04 are along a bending edge 11 ; 12 one bevelled suspension leg each 13 ; 14 formed, with the suspension legs 13 ; 14 in a narrow, in particular slit-shaped opening 09 of the canal 08 of the cylinder 06 ( 2 ) insertable and there by means of a holding device, for. B. a clamping device can be fastened. For example, based on the length L; L1; L2 of the arched, flat bearing surface 02a of the unassembled elevator 01 at the end 03 a suspension leg 13 at the bending edge 11 by an opening angle α1 or at the end 04 a suspension leg 14 at the bending edge 12 folded by an opening angle β1 ( 1 ), wherein the opening angle α1; β1 usually lie between 30 ° and 140 °. If the opening angle α1 the leading end 03 of the elevator 01 is assigned, it is preferably executed acute-angled, in particular it is 45 °. The opening angle β1 at the trailing end 04 of the elevator 01 is often formed preferably greater than 80 ° or obtuse, in particular, it is 85 ° or 135 °. The folded suspension leg 13 at the leading end 03 has a length L13, which z. B. in the range of 4 mm to 30 mm, in particular between 4 mm and 15 mm. The folded suspension leg 14 at the trailing end 04 has a length l14, the z. B. 4 mm to 30 mm, in particular between 8 mm and 12 mm, with the shorter length is preferred rather, as simple as possible to take out the suspension legs 13 ; 14 out of the opening 09 of the canal 08 to ensure.

The 2 shows in a simplified sectional view of a cylinder 06 with a lateral surface 07 and a channel 08 , to the lateral surface 07 a narrow, slot-shaped opening 09 having a slot width S, wherein the slot width S is less than 5 mm and preferably in the range of 1 mm to 3 mm. The opening 09 points in the direction of production P of the cylinder 06 a front edge 16 and a back edge 17 on. Between itself from the front edge 16 to the canal 08 extending wall 18 and an imaginary, on the lateral surface 07 of the cylinder 06 on the opening 09 lying tangent T09 is formed an acute opening angle α2, which is between 30 ° and 50 °, preferably 45 °. The folded suspension leg 13 at the leading end 03 of the elevator 01 is thus at this front edge 16 the opening 09 preferably form-fitting hooked, because the opening angle α1 at the leading end 03 of the elevator 01 is preferably adapted to the opening angle α2. In the same way it behaves at the trailing end 04 of the elevator 01 , Between itself from the rear edge 17 to the canal 08 extending wall 19 and an imaginary, on the lateral surface 07 of the cylinder 06 on the opening 09 lying tangent T09 is an opening angle β2 formed, which is either between 80 ° and 95 °, preferably 90 °, or between 120 ° and 150 °, preferably 135 °. The folded suspension leg 14 at the trailing end 04 of the elevator 01 is thus at this rear edge 17 the opening 09 preferably form-fitting hooked, because the opening angle β1 at the trailing end 04 of the elevator 01 is at least approximately adapted to the opening angle β2.

In the channel 08 are z. B. at least one preferably pivotally mounted holding means 21 and a preferably biased spring element 22 arranged, wherein the spring element 22 the holding means 21 z. B. against the folded suspension leg 14 at the trailing end 04 push that at the opening 09 at its rear edge 17 is suspended, causing the suspension leg 14 at the trailing end 04 from the rear edge 17 to the canal 08 extending wall 19 is held. To release the holding means 21 applied pressure is in the channel 08 an actuating agent 23 , preferably a pneumatically actuable actuating means 23 provided, which in its operation, the holding means 21 against the force of the spring element 22 swings. The holding device described by way of example consists essentially of the holding means 21 , the spring element 22 and the actuating means 23 ,

The cylinder described by way of example 06 is preferably such that on its lateral surface 07 several, preferably similar elevators 01 can be arranged. If the cylinder 06 is designed as a forme cylinder, it can in its axial direction side by side z. B. with up to six plate-shaped printing plates 01 be occupied. It is also preferably provided that on the cylinder 06 in the direction of its circumference more than a lift 01 can be arranged. So can in the cylinder 06 under its lateral surface 07 z. B. two axially to the cylinder 06 running channels 08 be provided for attachment of elevators 01 axially to the cylinder 06 running openings 09 have, wherein the openings 09 on the circumference of the cylinder 06 z. B. are offset by 180 ° to each other when on the cylinder 06 two elevators along its circumference 01 are to be arranged. With this assignment of the cylinder 06 with two elevators arranged one behind the other along its circumference 01 is the leading end 03 of a lift 01 in the one channel 08 attached, whereas the trailing end 04 the same elevator 01 in the other channel 08 is attached. For the one or the other on this cylinder 06 arranged elevators 01 applies accordingly. When in the axial direction of the cylinder 06 side by side several elevators 01 are arranged, they can advantageously be arranged offset from each other. The offset can z. B. individual lifts 01 or groups of elevators 01 relate, each z. B. by half a length L; L1; L2 of the elevator 01 arranged offset to each other, which, however, requires that more channels 08 with associated openings 09 or at least with parts of them in the cylinder 06 are introduced along the circumference of the cylinder 06 to the aforementioned channels 08 and openings 09 z. B. are arranged offset by 90 °.

The following is an example of a method for mounting a flexible elevator 01 on a cylinder 06 a printing machine described, wherein on the cylinder 06 along its circumference two elevators in a row 01 are locatable and where each elevator 01 with respect to the production direction P of the cylinder 06 a leading end 03 and a trailing end 04 having ( 3 ). At the leading end 03 of the elevator 01 is a suspension leg 13 formed, with this suspension leg 13 to the extended length L; L1; L2 of the elevator 01 is bent with an opening angle α1 of a maximum of 90 °, preferably 45 °. In the cylinder 06 are at least one preferably slot-shaped opening 09 with a direction of production P of the cylinder 06 first edge 16 and a second edge 17 provided, with the edges 16 ; 17 in the axial direction of the cylinder 06 preferably parallel to each other. The leading end 03 of the elevator 01 is z. B. by means of a trailing end 04 of the elevator 01 attacking thrust to the cylinder 06 preferably fed tangentially in the direction of production P until the suspension leg 13 at the leading end 03 behind the second edge 17 the opening 09 to the cylinder 06 pending, so that at the leading end 03 trained suspension leg 13 upon rotation of the cylinder 06 in its production direction P as a result of at least the leading end 03 acting, to the cylinder 06 directed radial force FR in the opening 09 grabs and gets to the first edge 16 hooked. In the event that the elevator 01 with his at the leading end 03 trained suspension leg 13 on the lateral surface 07 of the cylinder 06 standing up in support of it, the radial force FR z. B. on the lateral surface 07 of the cylinder 06 acting gravity FG of the elevator 01 be.

In addition to using the gravity FG of the elevator 01 or alternatively, the leading end 03 of the elevator 01 be resiliently biased ( 4 ), so that at the leading end 03 trained suspension leg 13 as a result of one on the cylinder 06 directed return torque MR in the opening 09 springs as soon as the opening 09 of the cylinder 06 and the touch line 27 the suspension gadget 13 with the lateral surface 07 of the cylinder 06 due to a relative movement between the elevator 01 and the cylinder 06 directly opposed, the relative movement in particular by the rotation of the cylinder 06 takes place in the production direction P.

The restoring moment MR therefore results that the elevator 01 consists of an elastically deformable material and thus immanently has an elastically resilient property, this property is used insofar as the leading end 03 of the elevator 01 when approaching the cylinder 06 z. B. via a preferably axially to the cylinder 06 running, from the cylinder 06 spaced edge 26 a support element 24 guided and bent there so that at the leading end 03 of the elevator 01 a bending stress with one to the cylinder 06 directed spring force builds up (dashed line of the elevator 01 in 4 ). At least that's over the edge 26 the support element 24 guided leading end 03 of the elevator 01 on the lateral surface 07 of the cylinder 06 gets up, gets the elevator 01 with its trailing end 04 from one to the cylinder 06 supplied fixed spatial direction. The elevator 01 is therefore during the assembly process by the contact line 27 his at the leading end 03 attached suspension gadget 13 with the lateral surface 07 of the cylinder 06 as well as by its support on the edge 26 the support element 24 and by a positional fixation 28 of the trailing end 04 stabilized. The support element 24 can z. B. as a rolling element 24 , in particular as a roller 24 or as one or more axially to the cylinder 06 juxtaposed rolls 24 be formed, the or the z.

Here are the attacks 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 attacks 52 ; 53 differ z. B. in its position relative to the axial direction of the forme cylinder 33 so that z. B. for a printing form 37 simple width of the stop 52 and for a printing form 37 in panorama format the stop 53 by a corresponding Swiveling the alignment device 51 is used. The attacks 52 ; 53 can be axial to the forme cylinder 33 for the required width of the printing form 37 be adjustable.

Of the 6 are also more details of the printing forme magazine 39 removable. That in the 6 to 35 embodiment shown is of a variant for the printing forme magazine 39 from where an upper shaft 44 for providing one on the forme cylinder 33 to be mounted printing form 37 as a separate unit independent of a lower shaft 42 for receiving a form cylinder 33 removed printing 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 charge of the forme cylinder 33 with new printing forms 37 should be automated, whereas the acceptance of used printing forms 37 is performed by an operator. If both shafts 42 ; 44 in the printing form magazine 39 are formed, results in a fully automatic pressure plate changer. Both shafts 42 ; 44 each have all for storing and conveying printing forms 37 required devices and are preferably constructed very compact. In particular, despite their receptivity, they each have at least two printing plates 37 a low height. The height is z. B. less than 150 mm, preferably less than 100 mm.

In the in the 6 to 35 the embodiment shown is the shaft 44 arranged horizontally and tangent to the aligned. This will affect the printing forme 37 applied gravity FG used in the best possible way to support the following described functions In the shaft 44 there is an edition 54 , on the one on the forme cylinder 33 to be mounted first printing form 37 with her folded hanging-in legs 13 ; 14 can be set up or stored. One on the pad 54 filed printing form 37 with a simple length L1 is z. B. with its entire extended length L; L1 on. The edition 54 is preferably not full surface, but in the form of parallel bars 54 or slide rails 54 educated. The suspension leg 14 at the trailing end 04 the first printing form 37 lies in the shaft 44 on the of the forme cylinder 33 side facing away from a preferably vertical stop 56 on, with the stop 56 from a conveyor 57 linear and parallel to the support 54 in the direction of the opening 039 of the printing forme magazine 39 is movable to this first printing form 37 by a translational movement and preferably free of deformation at least as long as from the shaft 44 to promote until the suspension leg 13 at the leading end 03 this first printing form 37 in the slot-shaped opening 09 of the forme cylinder 33 can grab. The stop 56 thus serves in the shaft 44 for the first printing form 37 as an investment position and at the same time has the function of a slider 56 , Unless this first printing form 37 on the suspension leg 14 at its trailing end 04 has at least one register punching, the stop 56 z. B. advantageously also as a perpendicular to the edition 54 standing, with the conveyor 57 linked register pin 56 be formed so that with the application of the first printing form 37 at the stop 56 for them a pre-registration with respect to their page register. The conveyor 57 is z. B. as a belt drive 57 or as a linear actuator 57 , preferably as a pneumatic linear drive 57 , in particular as a rodless, double-acting linear drive 57 educated.

In the shaft 44 there is a holder 58 , in particular printing form holder 58 for holding at least one second on the forme cylinder 33 to be mounted printing form 37 , As in 13 shown, becomes the second printing form 37 from the printing form holder 58 above the pad 54 ie at a distance a54 above the overlay 54 z. B. held by the fact that the printing form holder 58 for example, on the forme cylinder 33 opposite side one parallel to the support 54 movable piston 59 or slider 59 has, at the end of a holding element 61 , z. B. L-shaped angle formed 61 , is arranged, wherein the second printing form 37 above the pad 54 between the angle 61 of the extended slide 59 and one in the area of the opening 039 of the printing forme magazine 39 arranged another holding element 62 , z. B. a rigid stop 62 , is clamped. The distance a54 in this case has a value, preferably between twice and four times the length l14 of Einhänlegeels 14 at the trailing end 04 the second printing form 37 lies. The clamping of the second printing form 37 takes place in that a clear distance a58 between the angle 61 of the extended slide 59 and the stop 62 is set shorter than the stretched length L; L1 of the second printing form 37 , The stop 62 in the area of the opening 039 of the printing forme magazine 39 preferably has a chamfer 63 on, at which the suspension leg 13 at the leading end 03 the second printing form 37 can support, with the bevel 63 of the stop 62 and the L-shaped angle 61 , on which the suspension leg 14 at the trailing end 04 the second printing form 37 are supported, facing each other. Because the second printing form 37 in particular along its length L; L1 is bendable, she arched in her between the angle 61 and the stop 62 clamped state. The slider 59 of the printing form holder 58 is preferably linear parallel to the support 54 movable and preferably has two Stable operating positions, namely a stable operating position in the retracted, the second printing form 37 releasing state and in the extended, ie the second printing form 37 clamping state. In a variant for the printing form holder 58 are the arrangement of the movable slide 59 and rigid stop 62 swapped each other, so that the slider 59 in the area of the opening 039 of the printing forme magazine 39 and the stop 62 on the of the forme cylinder 33 located on the opposite side. As an alternative to the described linear mobility, the angle 61 or the stop 62 also around a width B parallel to the printing form 37 be aligned pivot axis arranged pivotally. One between the angle 61 and the stop 62 clamped printing form 37 is located at its upper or first storage position while one on the pad 54 filed printing form 37 assumes a lower, second storage position in this state, wherein the printing form 37 in the second storage position before being transported to the forme cylinder 33 is cached. By an operation, preferably by a remote from, z. B. made by a press belonging to the control console operation changes the printing form 37 inside the shaft 44 from its upper, first storage position to its lower, second storage position. in the first storage position and in the second storage position stored printing forms 37 each with a simple length L1 are spaced apart, z. 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 form holder 58 , which advantageously has a particularly low overall height for the shaft 44 allowed, provides the second printing form 37 above in the axial direction of the forme cylinder 33 in a single plane extending edition 54 with at least one retaining element 64 to hold in an upper storage position, wherein the retaining element 64 z. B. as a guide rail 64 , Preferably as two mutually parallel guide rails 64 , is trained ( 7 to 9 ), with the guide rails 64 the second in the shaft 44 located printing form 37 along its two longitudinal sides along at least part of its length L; Hold L1 in the upper storage position. The embodiment of the printing form holder 58 with guide rails 64 assumes that the suspension legs 13 ; 14 at the ends 03 ; 04 the second printing form 37 not over the full width B of the printing form 37 do not extend to the long sides of the printing form 37 come close. The long sides of the printing form 37 thus form in the area of the bearing surface 02a the printing form 37 a projection over the Einhänbringeln 13 ; 14 , This supernatant is necessary to the printing form 37 in the guide rails 64 to make it feasible. The holding element 64 , in particular, each guide rail 64 , z. B. from a U-shaped, each one of the long sides of the printing form 37 with a certain game encompassing strap, in which the second printing form 37 from the form cylinder 33 opposite side is inserted. The second printing form 37 is from the guide rails 64 thus preferably held in a narrow region of its side, wherein the holder in particular as a vertical support and thus as a support against the pressure on the form 37 attacking gravity FG acts. The guide rails 64 are preferably made of a dimensionally stable material such as metal or plastic.

To one of the guide rails 64 held second printing form 37 on the pad 54 is at least one of the guide rails 64 in the direction of the width B of the second printing form 37 movable. Preferably, however, both guide rails 64 along the width B of the second printing form 37 movable in opposite directions, so that they at least briefly move away from each other and increase their distance from each other such that they are the long sides of the printing form 37 no longer support vertically, eliminating the second printing form 37 due to the gravitational force FG acting on it between the guide rails 64 through to the pad 54 falls. If the retaining element 64 in a first operating state, the second printing form 37 z. B. holds by an electric or magnetic force in the upper storage position, the holding element changes 64 Preferably remotely controlled from its first operating state to a second operating state, wherein the second operating state, the holding element 64 causes the printing forme 37 and the holding element 64 solve each other and the printing form 37 when releasing 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 form 37 is in the lower and also in the upper storage position in the shaft 44 at an inclination of less than 15 °, preferably horizontal. At least they have as a support bearing for the second printing form 37 trained guide rails 64 in their longitudinal extent only this slight inclination or a horizontal course.

A release of the second printing form 37 from the side of her attacking guide rails 64 is preferably by a perpendicular to the support surface 02a the second printing form 37 standing stop 67 supported, preferably in the shaft 44 is arranged rigidly, wherein preferably on both longitudinal sides of the second printing form 37 such a stop 67 is arranged so that during one along the width B of the second printing form 37 directed, opposing movement of the this printing form 37 holding guide rails 64 this printing form 37 through the stops arranged on both sides 67 in the of the bearing surface 02a the printing form 37 spanned level remains stable. The attacks 67 strip the printing form 37 from the spaced guide rails 64 off by the printing form 37 at the attacks 67 strikes, at the same time the printing form 37 by the movement of the guide rails 64 the vertical support is withdrawn. The reading of the second printing form 37 is preferably carried out by a z. B. from the belonging to the printing press control station drive 69 , where the drive 69 on the guide rails 64 acts and she moves along a stehwegs s68.

Unless on the form cylinder 33 in the axial direction next to each other several printing plates 37 to arrange and in the shaft 44 in the axial direction of the forme cylinder 33 several printing forms 37 arranged side by side, it is advantageous to the guide rails 64 attached to adjacent second printing plates 37 attack, in the printing forme magazine 39 over the pad 54 in two different planes, that is to be arranged vertically offset from each other, wherein in the axial direction of the forme cylinder 33 successive planes are preferably arranged offset alternately. Due to the staggered arrangement of the first storage position of the printing plates 37 forming planes may be a distance a67 between in the axial direction of the forme cylinder 33 next to each other, ie adjacent pressure forms 37 be kept as low as possible. The distance a67 preferably corresponds in its value to a distance that on the forme cylinder 33 in the axial direction next to each other, ie adjacent arranged printing plates 37 exhibit. Off in the axial direction of the forme cylinder 33 juxtaposed planes, ie in each case from a first storage position, on the support 54 filed and thus each brought into their second storage position printing forms 37 can with the conveyor 57 the form cylinder 33 either individually or preferably simultaneously fed together, the latter approach for a quick change of printing plates 37 on the form cylinder 33 is advantageous. In the axial direction of the forme cylinder 33 in different juxtaposed planes stored printing forms 37 can switch simultaneously or at least in rapid succession to their respective second storage position. The form cylinder 33 at the same time jointly supplied printing forms 37 be on the form cylinder 33 arranged side by side in its axial direction.

In the in the 8th Example shown are four second printing plates 37 in each case in their first storage position in the axial direction of the forme cylinder 33 arranged side by side, each of these printing forms 37 each on their long sides in a guide rail 64 is held. 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 height of the guide rails 64 , preferably their single to double height. The movement of the guide rails 64 along the width B of the second printing form 37 takes place for. B. by a linear displacement of the guide rails 64 ; However, it can also by a pivoting movement of the guide rails 64 be executed, the guide rails 64 pivotable about a pivot axis, wherein the pivot axis parallel to that of the guide rails 64 supported side of the printing form 37 run. So can a guide rail 64 z. B. on at least one swivel arm 68 be appropriate, the z. B. in the of the bearing surface 02a the second printing form 37 hinged plane is pivotal, which is in the 9 indicated by a directional arrow. The swivel arm 68 one end of which is the guide rail 64 connected and the other end in the shaft 44 preferably attached fixed, z. B. as a side of the guide rail 64 acting spring element 68 , z.

As one of the forme cylinder 33 to be removed printing form 37 with your printed image page the guide element 73 touched, is her contact with a rotatably mounted rolling element 73 gentler for its surface than a gliding over a flat rigid wedge 73 , This aspect is particularly important when the printing form 37 to be used again and thus damage to their printed image page by scratches or marks to avoid. On the guide element 73 can be a sensor 91 be attached, either in contact with the forme cylinder 33 to be removed printing form 37 or advantageously contactless, e.g. B. inductive, checks if the suspension leg 14 at the trailing end 04 the from the form cylinder 33 to be removed printing form 37 after pressing the button in the channel 08 of the forme cylinder 33 arranged holding means 21 actually solved. With its test, the sensor sends 91 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 one from the forme cylinder 33 to be removed printing form 37 be continued or whether measures must be taken to remedy a disturbance. On the guide element 73 are in the axial direction of the forme cylinder 33 preferably several sensors 91 provided, z. B. four or six, namely at least one sensor 91 for each on the form cylinder 33 in the axial direction juxtaposed printing form 37 ,

In a preferred embodiment, the suspension leg sets 14 at the trailing end 04 the from the form cylinder 33 to be removed printing form 37 after passing the guide element 73 preferably on one of the guide element 73 spaced apart first ramp 74 on before he restarts the edition 72 in the shaft 42 achieved, with the first ramp 74 in the direction of the edition 72 initially rises and after a peak 76 for circulation 72 back down again. The first ramp 74 is preferably rigid with the support 72 connected. In progress of introduction of the forme cylinder 33 to be removed printing form 37 in the shaft 42 meets her hanging leg 14 at the trailing end 04 on a second ramp 77 whose flank after its peak 78 ie on the form cylinder 33 opposite side, preferably abruptly steep to support 72 falls off. In the direction in which the printing form 37 in the shaft 42 is introduced at a short distance a77 ( 14 ) behind the summit 78 one with the second ramp 77 rigidly connected stop 79 arranged on the suspension leg 14 at the trailing end 04 the printing form 37 strikes. The distance a77 in this case has a value of a few millimeters, preferably a value of less than the simple length l14, in particular less than half the length l14 of the folded Einhängebelt 14 at the trailing end 04 the printing form 37 , Warm the suspension leg 14 at the trailing end 04 the printing form 37 to the stop 79 strikes, he preferably engages behind the second ramp 77 by the suspension leg 14 engages in the gap formed by the distance a77. The second ramp 77 and the stop associated with it 79 are through a conveyor 81 linear and parallel to the support 72 movable to that of the forme cylinder 33 to be removed printing form 37 by one at the trailing end 04 completely pulling force into the shaft 42 to carry in. The conveyor 81 in particular, along with the steep flank on the second ramp 77 for the folded suspension leg 14 at the trailing end 04 the printing form 37 one the printing form 37 in the shaft 42 promotional entrainment means forms, for. B. as a belt drive 81 or as a linear actuator 81 , preferably as a pneumatic linear drive 81 , in particular as a rodless, double-acting linear drive 81 educated. Both the first ramp 74 as well as the second ramp 77 exist z. B. not from full-surface planes, but from several parallel as the tines of a comb arranged guide rails. The second ramp 77 can z. B. be formed from one or more correspondingly bent metal strip.

On the of the form cylinder 33 opposite side is in the shaft 42 a lift 82 , in particular a printing form lifter 82 arranged, wherein the printing form lifter 82 for example, a preferably perpendicular to the edition 72 movable piston 83 has, at the end of a z. B. L-shaped, in particular U-shaped lifting arm 84 is arranged, wherein the folded suspension leg 14 at the trailing end 04 the printing form 37 on the lifting arm 84 is set up or comprehensively adjusted. The printing form lifter 82 preferably has two stable operating positions, namely a stable operating position with retracted piston 83 in which the lifting arm 84 below the through the pad 72 defined levels, and another stable operating position with extended piston 83 in which the lifting arm 84 the from the form cylinder 33 removed printing form 37 from the edition 72 raising. The printing form lifter 82 In doing so, it executes a stroke s82, which is greater than the length l14 of the folded-in suspension girder 14 at the trailing end 04 the printing form 37 , Preferably, the stroke s82 has a value between the single length and the double length l14 of the suspension girder 14 on. The printing form lifter 82 thus raises one from the forme cylinder 33 removed printing form 37 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 is a preferably about a substantially parallel to the width B of the printing plate 37 extending pivot axis pivoting fuse element 86 arranged, z. B. in the form of a strip-shaped flap 86 whose lower edge is at a distance a86 from the lifting arm 84 is located, wherein the distance a86 is preferably dimensioned smaller than the length l14 of the folded Einhänlegeels 14 at the trailing end 04 the printing form 37 , In the 6 indicates a direction arrow the pivoting of the fuse element 86 at. The fuse element 86 secures one from the printing form lifter 82 raised printing form 37 against unintentional slipping in the shaft 42 or a removal from the shaft 42 , So an operator has the fuse element 86 first to pivot before the raised printing form 37 from the shaft 42 can be removed.

Another embodiment for in the shaft 42 arranged assemblies is in the 10 to 12 shown. This embodiment sees one preferably in the middle region of the support 72 rigidly arranged stop 79 before, being one with a linear along the overlay 72 movable conveyor 81 connected printing form lifter 82 the folded suspension leg 14 at the trailing end 04 one from the form cylinder 33 to be removed printing form 37 about the stop 79 lifts and the printing form 37 on her bent suspension leg 14 preferably in their from the printing form lifter 82 raised state to that of the forme cylinder 33 opposite end of the shaft 42 draws. The conveyor 81 and the printing form lifter 82 can be positively coupled so that the printing form lifter 82 the folded suspension leg 14 the printing form 37 then lifts as soon as the conveyor 81 a movement in the form cylinder 33 executes the opposite direction. Furthermore, between the stop 79 and the form cylinder 33 facing the end of the shaft 42 another printing form lifter 87 provided, the leading end 03 one from the form cylinder 33 removed, into the shaft 42 introduced printing form 37 so far raises that another from the forme cylinder 33 to be removed printing form 37 between the edition 72 and the raised printing form 37 in the shaft 42 is insertable.

Based on 13 to 35 Now, in particular, methods for changing printing forms 37 on a form cylinder 33 explained. It is assumed that in the upper bay 44 to provide new ones on the forme cylinder 33 to be mounted printing forms 37 two printing forms 37 are arranged on the forme cylinder 33 along the circumference of two printing plates 37 are hung up and that the lower shaft 42 to Recording from the form cylinder 33 distant printing forms 37 empty, ie free of printing forms 37 is.

The form cylinder 33 turns the opening 09 a channel 08 , in which the suspension leg 14 at the trailing end 04 the from the form cylinder 33 to be removed printing form 37 from a holding means 21 held in a first position, which is below the lower shaft 42 belonging guide element 73 located. The controllable, preferably pneumatically actuated pressure element 24 gets to the form cylinder 33 employed ( 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 the printing form 37 due to its elastic residual stress from the opening 09 snaps and on the guide element 73 strikes. The employed pressure element 24 secures the printing form 37 against a further release of the lateral surface 07 of the forme cylinder 33 ( 14 ).

The form cylinder 33 rotates counter to its production direction P and pushes the trailing end 04 the printing form 37 in the shaft 42 , At the introduction of the printing form 37 in the shaft 42 slides the suspension leg 14 at the trailing end 04 this printing form 37 first on the guide element 73 along and then turns on the to the shaft 42 belonging first ramp 74 on. The suspension leg 14 slides the ramp 74 up to over the summit 76 and then reaches the circulation 72 , While the pressing element 24 continue on the forme cylinder 33 is employed, becomes the printing form 37 by the rotation of the forme cylinder 33 contrary to its production direction P further into the shaft 42 inserted. In doing so, you overcome the hanging leg 14 at the trailing end 04 also with the conveyor 81 connected second ramp 77 and bumps into the second ramp 77 connected stop 79 ( 15 ).

The pressing element 24 is from the form cylinder 33 switched off. Through the bump of the suspension gadget 14 of the trailing end 04 at the stop 79 dissolves the preferably positive fit on the front edge 16 the opening 09 hinged folded legs 13 at the leading end 03 the printing form 37 out of the opening 09 , The printing form 37 is now with its leading end 03 free on the lateral surface 07 of the forme cylinder 33 on. The form cylinder 33 has from loosening the suspension gadget 14 at the trailing end 04 less than half a turn done so far. The folded suspension leg 14 at the trailing end 04 has between the second ramp 77 and the stop 79 hooked. The second ramp 77 and the stop 79 connected conveyor 81 can the printing form 37 now completely in the shaft 42 move in ( 16 ).

The printing form 37 is from the form cylinder 33 removed and is L its length; L1 to the shaft 42 , Your suspension leg 14 at the trailing end 04 is on the summit 78 the second ramp 77 on while your fore end 03 on the summit 76 the first ramp 74 rests, whereby at least the suspension leg 13 at the leading end 03 preferably free hanging. The storage of the printing form 37 in the shaft 42 is therefore preferably by a support at two points, namely on the summit points 76 ; 78 the two ramps 74 ; 77 ( 17 ).

The z. B. pneumatically actuated Druckformheber 82 lift them into the shaft 42 retracted printing form 37 at its trailing end 04 until just below the fuse element 86 on, with the suspension leg 14 on the with the printing form lifter 82 connected lifting arm 84 gets up ( 18 ).

While a first on the form cylinder 33 to be mounted printing form 37 with her folded hanging-in legs 13 ; 14 on the pad 54 in the upper bay 44 gets up, turns the form cylinder 33 continue counter to its direction of production P in a second position until the opening 09 , from which the suspension leg 13 at the leading end 03 the previously from the form cylinder 33 removed printing form 37 was resolved, a Aufstandspunkt 88 the to the form cylinder 33 employed pressing element 24 has happened and in the production direction P of the forme cylinder 33 rear edge 17 the opening 09 at a distance a88 from the contact point 88 distance, wherein the distance a88 is in the range of a few millimeters, preferably less than 30 mm, and thus an arc length of less than a thirtieth part of the circumference of the forme cylinder 33 equivalent. The first position of the forme cylinder 33 for removing a print form arranged thereon 37 is usually not identical to its second position for receiving a new printing form 37 , The pressing element 24 is preferably to the form cylinder 33 hired while the opening 09 the point of contact 88 happened or after getting the point of contact 88 happened. The close to the form cylinder 33 arranged alignment device 51 pivots with their previously preferably horizontally oriented diametrical stops 52 ; 53 preferably by 90 ° in a vertical position, so that one on the width B of the forme cylinder 33 to be mounted printing form 37 coordinated stop 52 ; 53 in one by the edition 54 in the shaft 44 defined transport level for those on the form cylinder 33 to be mounted printing form 37 dips and those on the form cylinder 33 to be mounted printing form 37 during their transport out of the shaft 44 at the stop 52 ; 53 page register moderate to form cylinder 33 is aligned ( 19 ).

The on the form cylinder 33 to be mounted first printing form 37 stands with her suspension leg 14 at its trailing end 04 on with a conveyor 57 connected stop 56 at. The conveyor 57 is put into operation, so the stop 56 in a preferably tangential to the form cylinder 33 directed movement the first printing form 37 far from the shaft 44 promoted until its leading end 03 that to the form cylinder 33 employed pressing element 24 touched and the at this leading end 03 folded suspension legs 13 between in the direction of production P of the forme cylinder 33 rear edge 17 the opening 09 and the point of contact 88 of the pressure element 24 on the form cylinder 33 gets up ( 20 ).

The form cylinder 33 changes its direction of rotation and begins to rotate in its production direction P, causing the on the forme cylinder 33 mounted suspension leg 13 at the leading end 03 the printing form 37 in the opening 09 slips and preferably form-fitting at the front edge 16 the opening 09 mounted ( 21 ).

By the further rotation of the forme cylinder 33 in his production direction P is the with her suspension leg 13 in the opening 09 hinged printing form 37 completely out of the shaft 44 transported out and on the form cylinder 33 reared. During winding, the printing form becomes 37 through the to the form cylinder 33 employed pressing element 24 on the form cylinder 33 rolled on. After half a revolution of the forme cylinder 33 in his direction of production P presses the pressure element 24 the folded suspension leg 14 at the trailing end 04 the printing form 37 in the opening 09 , The holding means 21 in the to this opening 09 belonging channel 08 was solved and is then brought into the operating position in which it in the opening 09 inserted suspension leg 14 at the trailing end 04 the printing form 37 z. B. fixed by a clamp. The conveyor 57 drives the stop connected to it 56 back to its final position on the forme cylinder 33 opposite side in the shaft 44 ( 22 ).

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

The change of another, z. B. on the form cylinder 33 along its circumference arranged second printing form 37 begins with that preferably still during the previous ongoing production of an operator, the new second printing form 37 in the shaft 44 is inserted. This is the second printing form 37 from a controllable, preferably pneumatically controllable printing form holder 58 over the pad 54 held by the printing form 37 z. B. either at their ends 03 ; 04 between two stops 61 ; 62 is clamped, with at least one of the attacks 61 ; 62 is movable, or by the printing form 37 on their long sides in guide rails 64 is inserted, wherein at least one of the guide rails 64 along the width B of the printing form 37 is movable. When the printing form holder 58 the printing form 37 releases it by pushing the printing form 37 holding elements, eg. B. the attacks 61 ; 62 or the guide rails 64 , their distance, z. B. a58, each other at least briefly increase, the printing form falls 37 on the edition 54 and is standing there with her hanging up 13 ; 14 on ( 24 ).

To another, z. B. second printing form 37 from the form cylinder 33 The form cylinder rotates 33 according to the 13 explained the opening procedure 09 of the canal 08 , in which the suspension leg 14 at the trailing end 04 the from the form cylinder 33 to be removed second printing form 37 from a holding means 21 is held in the first position, which is below the lower shaft 42 belonging guide element 73 located. The controllable, preferably pneumatically actuated pressure element 24 gets to the form cylinder 33 employed ( 25 ).

According to the to 14 explained method pivots the preferably pneumatically operable actuating means 23 the holding means 21 against the force of the spring element 22 , whereby the suspension leg 14 at the trailing end 04 the second printing form 37 due to its elastic residual stress from the opening 09 snaps and on the guide element 73 strikes. The employed pressure element 24 secures the second printing form 37 against a further release of the lateral surface 07 of the forme cylinder 33 ( 26 ).

The form cylinder 33 rotates counter to its production direction P and pushes the trailing end 04 the second printing form 37 in the shaft 42 , At the introduction of the printing form 37 in the shaft 42 slides the suspension leg 14 at the trailing end 04 this printing form 37 first on the guide element 73 along and then turns on the to the shaft 42 belonging first ramp 74 on. The suspension leg 14 the second printing form 37 slides the ramp 74 upwards, taking himself under the shaft 42 dormant, on the summit point 76 the first ramp 74 resting first printing form 37 pushes and theirs at the summit point 76 overhanging, to form cylinder 33 directed leading end 03 lifts, while the suspension leg 14 the second printing form 37 the summit point 76 the first ramp 74 exceeds and then the edition 72 reached. While the pressing element 24 continue on the forme cylinder 33 is employed, becomes the second printing form 37 by the rotation of the forme cylinder 33 contrary to its production direction P further into the shaft 42 inserted. At the same time the suspension leg slides 13 at the leading end 03 the one in the shaft 42 resting first printing form 37 over the printed image side of the manhole 42 funded second printing form 37 , In the further course overcomes the suspension leg 14 at the trailing end 04 the second printing form 37 also with the conveyor 81 connected second ramp 77 and bumps into the second ramp 77 connected stop 79 ( 27 ).

The pressing element 24 is from the form cylinder 33 switched off. Through the bump of the suspension gadget 14 of the trailing end 04 at the stop 79 dissolves the preferably positive fit on the front edge 16 the opening 09 hinged folded legs 13 at the leading end 03 the second printing form 37 out of the opening 09 , The suspension leg 13 with its leading end 03 is now free on the lateral surface 07 of the forme cylinder 33 on. The form cylinder 33 has from loosening the suspension gadget 14 at the trailing end 04 until now less than half a turn done. The folded suspension leg 14 at the trailing end 04 hooks between the second ramp 77 and the stop 79 one.
