Individual or combinations of features of the embodiment described below for the transport system 18 . 23 are - where reasonably possible or not contradictory - to the configuration variants mentioned above in the description of the overall system for the formation of the printing unit 01 and the equipment of the printing unit 01 with system components 17 ; 18 ; 19 ; 21 ; 22 ; 23 transferred to.

As already mentioned, the transfer unit works 18 together with the guidance system 23 ; 23.1 ; 23.2 the transport of the newly applied printing form 06 from a position cylinder-distant or pressure-form-carrier-close pickup position P18.1 to a transfer position P18.2 close to the form cylinder. This is done by the transfer unit 18 in the first position P18.1 the printing form to be applied 06 from one the printing form 06 carrying printing plate support 17 on, which in principle can be arbitrarily executed. z. B., it may be formed as a simple edition, on which the printing plates 06 be stored manually or by a manipulator, or as a multi-day storage or frame system in which several printing forms 06 are kept in superimposed manholes or guides. Regardless of the specific design, the transfer unit should 18 Access to the still in or on the printing plate carrier 17 stationary printing form 06 have, so there is no own propulsion mechanism for the printing plates 06 must be provided. In a preferred embodiment, therefore, finds a printing plate 17 Application, which according to one of the embodiments of the memory device described above 17 is trained. In this embodiment, the transfer unit 18 unhindered on the surface of the aufzulegenden, still in storage position located printing form 06 in a confined space, ie without major differences in the place of initial contact between transfer unit 18 and respective printing form 06 , a plurality of printing plates to be placed one after another 06 is to be held up.

The transfer unit 18 extends in the printing unit 01 parallel to the forme cylinder axis (see eg 3 ). It points in the axial direction of the forme cylinder 03 considers at least one length L18 to coincide with each of the sections a ₁ ; a ₂ ; a ₃ ; a ₄ for receiving the m on the forme cylinder 03 juxtaposed printing forms 06 at least partially overlapping (see eg 9 ). Preferably, it extends over the entire nominal width W _{N of} the forme cylinder to be loaded 03 , It comprises a mono- or multi-part design, extending over the length L18 traverse 61 , and at least one receiving device 62 , z. B. holding device 62 which is at least the number m of the maximum through the forme cylinder 03 juxtaposed printing forms 06 corresponding number p of receiving elements 63 , z. B. holding elements 63 , or groups of several, e.g. B. two, recording or holding elements 63 includes. The recording elements 63 are - at least in the idle state (not employed) - preferably in one to the longitudinal axis of the transfer unit 18 arranged parallel flight. The recording elements 63 can in principle be formed with arbitrarily designed receiving means, provided they take up and carrying a printing forme 06 grant. For example, the recording could be based on magnetic effect and the recording elements 63 have receiving means designed as permanent magnets or electromagnets. Likewise, a mechanical gripping by appropriate, with the printing plates 06 be provided cooperating gripper.

In view of the risk of tilting, however, the present embodiment is of particular advantage, each suction cup 64 mechanically independent of the other suction cups 64 the receiving device 62 perpendicular to the longitudinal axis of the traverse 61 or transfer device 18 is mounted relatively movable. The movement takes place for example via actuators 66 . 67 which in principle can be arbitrarily formed, for example as motors, based on magnetic forces or on pressure means. The movement can be done as a linear movement or in the manner of a pivoting movement via a lever. In a preferred embodiment, the drive is based on actuators which can be beaten with pressure means 66 . 67 , For this purpose, the receiving elements include 63 for example, in each case a truss-fixed, acted upon by pressure cylinder 66 in which one with the sucker 64 over a pestle 67 connected piston is running (or vice versa). In alternative, the pestle could 67 also act on a lever arm and on this pivotally mounted suction cup 64 pivot.

A place of the switch 27 is preferably via a drive means 94 which z. B. basically as a drive motor 94 or as actuatable by pressure medium actuator 94 can be trained. In training as a drive motor 94 For example, by limit switches or by resistance-related shutdown and corresponding stops, ensure that defined positions are reached and then a shutdown occurs. In here shown, advantageous embodiment, the points made the switch 27 by actuation of an actuatable with pressure medium actuator 94 , z. B. pneumatic or hydraulic cylinder 94 through which a relative movement between side frame 04 , z. B. a frame-fixed bracket 96 , and points section 84.3 along the travel path S27 takes place (see, for. 16 ). In the formation of the drive means 94 as actuatable by pressure medium actuator 94 can - as preferred and shown here - the pneumatic or hydraulic cylinder 94 be arranged fixed to the frame and the switch section to be moved 84.3 medium or immediate, over z.

In principle, regardless of whether the transport system 18 . 23 with a single transport path 23 , with several transport paths 23.1 ; 23.2 and / or with a switch 27 is formed, a positioning device already mentioned above 28 , z. B. formed as a device for variable path limitation 28 , such as the transport system 18 . 23 or leadership system 23 to be assigned stop device 28 and / or sensor arrangement 28 , in the off-axis area of the transport path 23 ; 23.1 ; 23.2 be provided. Through these are the transfer unit 18 for picking up a new printing form 06 to be taken receiving position P18.1 defined assignable at least two different along the present in this receiving area transport direction T1 spaced locations. Alternatively, it can also be a position transmitter on the drive motor 77 or be provided in the controller associated therewith acting as a "position device". Depending on the technical or mechanical condition of the positioning device 28 takes the transfer unit 18 on the transport path 23 ; 23.1 ; 23.2 in their picking position P18.1 different positions on the transport path 23 ; 23.1 ; 23.2 , In particular at least slightly spaced positions or positions in the receiving area P18.1 of the transport path 23 ; 23.1 ; 23.2 one.

These, optionally several defined positions for the picking position P18.1 presetting positioning device 28 is particularly advantageous in connection with an embodiment of the printing plate changing system, wherein the transport system 18 . 23 in a receiving area P18.1 with a printing form memory 17 works together in which the printing forms 06 in the transport direction T1 of a transfer unit located in pickup position P18.1 18 considered with their ends 09 ; 11 , in particular leading ends 09 , Are arranged offset from one another, as for example for the execution of the above-mentioned memory device 17 the case is. In a non-illustrated embodiment, such a positioning device 28 be formed by an at least the number of different positions or positions corresponding number of spaced apart in the transport direction T1 initiators, z. As contacts, switches or contactless switching elements (magnetically or optically acting) are provided which the presence or absence of the transfer unit 18 or recognize the front side guide carriage. A control circuit or a control program can then be designed such that conveying the transfer unit 18 in the direction of the cylinder-distal end of the transport path 23 each until it reaches the desired end position associated switching state and upon reaching this switching state of the drive, for. B. the transfer unit 18 promoting drive, z. B. the drive motor 77 , turns off. For example, the drive motor would be 77 for the cylinder-distal position to switch off only if the initiator representing the furthest cylinder position the presence of the transfer unit 18 or their carriages detected.

In an illustrated embodiment of the positioning device 28 This is considered the way mechanically by a number of stop elements 101 , short attacks 101 formed limiting system, wherein the effective as travel limit stop surfaces in the transport path from each other according to the required for the different positions path differences are spaced from each other. Thus, for example, a last, the way to formzylinderfernen end limiting stop 101 fixed (possibly adjustable) arranged while a number of formzylindernhn arranged in the transport path stops 101 optionally in and out of engagement with one of the transport unit 18 attributable stop can be brought. At the transport unit 18 Assigned stop, a switching element may be provided, through which in cooperation with one of the stops 101 the transfer unit 18 promoting drive, z. B. the drive motor 77 , is switched off. However, a motor control can also be provided such that the motor is switched off due to the resistance resulting from the impact and the concomitant change in the electrical power or the applied torque. In the example given, the movable stops 101 by moving along a travel S101 in or disengageable, which has at least one perpendicular to the transport direction T1 movement component, in particular linear and perpendicular to the transport direction T1 extends. In the illustrated embodiment, the attacks 101 in an axial direction of the transfer unit 18 parallel adjusting direction S101 movable.

In an advantageous application of a memory device 17 with offset in the transport direction T1 Druckformenden 09 , z. B. a printing plate 17 in the above version, is by the positioning device 28 ensures that the recording device 71 every printing form 06 at the same distance from the leading end 09 attacks. The circuit or programming of the positioning device 28 is to be adjusted accordingly to the expiry of the printing plate change.

After taking the printing form 06 or more printing forms 06 this will or will this through the transfer unit 18 over the transport path 23 ; 23.1 ; 23.2 brought to the cylinder-near transfer position P18.2. The subsequent transfer can be made directly to the form cylinder 03 or to a cylinder-near investment facility 19 respectively. The steps described below and any aids used (eg investment facility 19 and / or pressing device 21 ) are basically of the above-described expression of the transport system 18 . 23 and / or the storage device 17 independently, but in conjunction with one or more of the features of the described embodiments for the memory device 17 and / or the transfer unit 18 and / or the guidance system 23 of particular advantage.

In one, with regard to the installed system components ( 17 ; 18 ; 19 ; 21 ; 22 ; 23 ) simpler design of the printing plate changing system is the recorded printing form 06 or are the recorded printing forms 06 from the transfer unit 18 with her end 09 or their ends 09 directly, essentially tangentially, to the forme cylinder to be loaded 03 spent, so that the z. B. in the acute interior angle bent end 09 , z. B. within an angular range of ± 15 ° from the tangential contact point comes in touching contact (see, eg. 17 ). The printing form 06 is still at this time by the receiving device 62 or their holding elements 63 held. Preferably, the printing form 06 in height and longitudinal orientation in such a way to the form cylinder 03 introduced that they at least in the longitudinal region of the fixation by the holding device 62 or their suction cups 64 with a tangent T03 of the forme cylinder 03 is aligned (eg maximum deviation ± 2 mm in height), due to the z. B. lying well below 1 mm Strength of the printing form 03 the position of the tangent T03 in the printing form cross section should be negligible. Through the bent end 09 , with z. B. an actual height of at least 5 mm, it undergoes a bending and thus in the radial direction of the forme cylinder when placed or run on the form cylinder jacket surface 03 acting bias so that they arrive at the opening 07 at least with part of the end 09 in the channel 08 dips. For example, to support the hanging and / or preferably for winding a pressing device described in more detail below 21 provided, which possibly the leading end 09 in the channel 08 press as soon as the opening 07 on the form cylinder 03 and the edge of the leading end 09 aligned with each other.

The form cylinder 03 is for the mounting of new printing plates 06 preferably before or possibly after the introduction of the printing form 06 turned into the predetermined position for hanging. After the end 09 - If necessary, with the support of the pressing device 21 - in the canal 08 and possibly additionally secured there by appropriate means, the form cylinder 03 twisted so that he the printing form 06 gradually rolled up on its lateral surface. This can be done on the printing plate 06 rolling rollers of the pressing device 21 support a safe and even winding or winding. During winding, the receiving elements can 63 continue to be effective, possibly with reduced holding force to the printing plate 06 until leaving the effective range of the receiving device 62 to hold and / or to lead. In an embodiment of the retaining elements 63 with suction cups 64 can the negative pressure, possibly reduced, be maintained, the forme cylinder 03 the printing form 06 against the holding force under the receiving or holding device 62 pull away, leaving the still-active suction cups 64 z. B. forcibly slide on the printing form surface. When the printing form 06 is completely wound up, the other press-forming comes 11 over the same (single-round design) or over a circumferentially offset opening 07 (Double-round design) to lie and will, preferably with the support of the pressing device 21 , in the channel 08 pressed and there z. B. held by appropriate means.

In a more complex, but with regard to possible disturbances even more robust design, especially if also printing plates 06 particularly large dimension and / or low strength and / or pressure forms 06 different strengths and / or dimensions should be used, the printing plate 06 or are the printing forms 06 initially to a formzylindernahe investment facility 19 pass before moving on the perimeter of the forme cylinder 03 is wound up. The investment facility 19 ensures, among other things, that the printing forms 06 occupy a frame-defined position and, in an advantageous embodiment with a holding device 102 , a defined retention force and / or a force for a desired deformation can be applied.

The investment facility 19 extends in the printing unit 01 parallel to the forme cylinder axis (see eg 4 ). It points in the axial direction of the forme cylinder 03 consider at least one length L19 so that they coincide with each of the in 18 indicated sections a ₁ ; a ₂ ; a ₃ ; a ₄ = (a _m for the m-th section) to accommodate the maximum m on the forme cylinder 03 juxtaposed printing forms 06 at least partially overlapping (see eg 18 , here again with m = 4). Preferably, it extends over the entire nominal width W _{N of} the forme cylinder to be loaded 03 , It comprises a mono- or multi-part design over at least the length of the m sections a ₁ ; a ₂ ; a ₃ ; a ₄ extending shelf 103 which either directly an upper side of an axially extending, frontally on the side frame 04 mounted, not visible here Traverse, or as shown, the top of a arranged on a frontally mounted cross member cover 104 , In the simplest version, the printing form 06 or are the printing forms 06 through the transfer unit 18 on the shelf 103 filed when the edge of the leading end 09 with the opening 07 of the canal 08 flees. The edge hooks at least partially, so that they turn when turning the forme cylinder 03 in the direction indicated by dashed arrows direction of rotation now further drawn and in the course of the printing form 06 on the form cylinder 03 is wound up.

Preferably, the investment device 19 however, with the above-mentioned holding device 102 formed, which is at least the number m of the maximum by the forme cylinder 03 juxtaposed printing forms 06 corresponding number of retaining elements 106 , or optionally groups of several, eg. B. two, holding elements 106 includes (see eg 18 and 19 ). The holding elements 106 are preferably in one to the longitudinal axis of the investment device 19 arranged parallel flight. The holding elements 106 can in principle be formed with arbitrarily executed holding means, provided they hold a printing forme 06 grant. For example, the holding could be based on magnetic effect and the holding elements 106 have recording means designed as permanent magnets or electromagnets (if the printing forme 06 corresponding magnetisiebare shares has). Likewise, a mechanical gripping by appropriate, with the printing plates 06 be provided cooperating gripper. However, preferred is an embodiment in which the Hold based on negative pressure, the holding device 102 as a suction device 102 is formed and the individual holding elements 106 as holding means suction cups 107 include. Preferably, each axially adjacent to each other to be arranged printing plate 06 or per section a ₁ ; a ₂ ; a ₃ ; a ₄ a holding element 106 with a suction cup 107 in the middle of section a ₁ ; a ₂ ; a ₃ ; a ₄ provided. Now through the transfer unit 18 or possibly also manually a printing plate 06 on the shelf 103 in the corresponding section a ₁ ; a ₂ ; a ₃ ; a ₄ off or on (possibly also with the application of a slight pressing force), it is with activated holding element 106 , z. B. applied negative pressure, the printing plate 06 frictionally engaged on the shelf 103 held and is only against a resistance by turning the forme cylinder 03 in its direction. The shelf 103 is in this embodiment at the same time as a large-area bearing surface 103 effective.

In an advantageous development are in the storage area 103 on both sides, preferably on an at least overlapping same height in the longitudinal direction of the printing form 06 considered, support elements 108 provided, which slightly, z. B. by a maximum of 2 mm, over the surface of the shelf 103 protrude. The free ends of the retaining elements 106 , z. B. the suction cups 107 , can also be inactive from the surface of the shelf 103 in particular, they can stand out what the height is above the counter space 103 relates, in the inactive state substantially with the bearing surfaces of the support elements 108 aligned or at a height between the surface of the support elements 108 and the surface of the shelf 103 lie. The holding element 106 and / or the support elements 108 can in a development in the amount of their supernatant against the shelf space 103 and / or adjustable relative to each other in their relative height.

In principle, the retaining elements 106 operationally slightly, z. B. at least 1/10 mm, in a direction perpendicular to the shelf 103 be movably mounted and formed by possibly at least one actuator movable. In training the holding elements 106 with suction cups 107 However, this is not necessary if the suction cup 107 in an advantageous embodiment in its height due to elastic property by application of negative pressure slightly, z. B. by at least 0.05 mm, z. B. 1/10 mm, is changeable. In this case, the suction cup tightens 107 when sucking the printing form 06 slightly, z. B. by 1 to 4 mm, together. The printing form 06 is thereby sucked, against the support elements 101 supporting, in relation to the plane of the shelf 103 slightly convexly bent. An insertion in the canal 08 , first in a central area of the printing form 06 is thereby facilitated. Preferably, in the central region of the leading pressure forming end 09 a recess provided, which with a in the channel 08 arranged, corresponding register element positively cooperates with respect to the page register.

The investment facility 19 is, for example, operationally fixed to the frame on the front side in or on the side frame 04 stored. In an advantageous development, however, it is for assembly and / or maintenance purposes of the same or a component of the printing unit 02 about a parallel to the form cylinder axis pivot axis S19 pivoted away from the work area. For this purpose, it has, for example, the front side lever 109 on which on the side frame 04 are pivotally mounted. One of the pivotal movement assisting drive does not necessarily, since the pivoting is preferably not operationally, but only for maintenance. A supporting drive can, however, for particularly wide, z. B. three-width printing units 02 , and therefore particularly long and heavy investment facilities 19 be provided.

As in 20 comparable to 17 shown, the printing form 06 even when using a facility 19 through the transfer unit 18 or by their holding device 62 with the edge of its leading end 09 over the opening 07 of the canal 08 promoted. However, the printing form becomes 06 before turning the forme cylinder 03 takes place on the shelf 103 placed or even put on with slight pressure, so that the printing form 06 with the holding element 106 or its suction cup 107 comes into contact. The holding element 106 or the suction cup 107 is now activated, ie in the case of the suction cup 107 subjected to negative pressure. In the event that above bearing elements 108 are provided, the printing plate 06 bent and at the same time retained frictionally against movement in the transport direction. By subsequently turning the forme cylinder 03 slips the previously only partially engaging edge of the leading end 09 now completely in the channel 08 and is used by the retention force against the channel edge and thereby aligned. Preferably, the support surface is aligned 103 , or in the presence of above bearing elements 108 their contact surfaces with a tangent T03 of the forme cylinder 03 , After activation of the retaining element 106 experiences the printing form 06 then that too 17 described deflection and bias.

In 17 to 20 is the investment facility 19 with substantially or at least predominantly horizontal extension of its shelf 103 or the printing forms to be placed 06 explained. As on the upper printing unit 02 of the 1 . 3 and 4 recognizable, the conditioning apparatus 19 , in particular those with holding elements 106 executed investment device 19 , also be particularly advantageous if the shelf space 103 or the printing forms to be placed 06 in the longitudinal direction predominantly vertical, in particular z. B. extends substantially vertically. That to the horizontally arranged investment facility 19 in terms of their design and their interaction with the forme cylinder 03 and / or the transfer unit 18 as well as with respect to their relative position and orientation relative to each other is to be applied mutatis mutandis to the horizontally inclined, on the predominantly vertically extending and on the substantially vertically oriented arrangement.

As already mentioned, a pressing device can be used to assist hooking and / or winding 21 be provided (see, for example, 21 and 22 ).

The pressing device 21 extends in the printing unit 01 parallel to the forme cylinder axis (see eg 21 ). It points in the axial direction of the forme cylinder 03 contemplates at least one length L21 to coincide with each of the sections a ₁ ; a ₂ ; a ₃ ; a ₄ for receiving the m on the forme cylinder 03 juxtaposed printing forms 06 at least partially overlapping. Preferably, it extends over the entire nominal width W _{N of} the forme cylinder to be loaded 03 , It comprises a mono- or multi-part trained, over the length L21 extending traverse 111 , on which side by side at least a number m of the maximum through the forme cylinder 03 juxtaposed printing forms 06 corresponding number of pressing elements 112 , preferably as pressure rollers 112 executed, or groups of several, z. B. two, pressing elements 112 includes. The pressing elements 112 are - at least in the idle state (ie not to the form cylinder 03 employed) - preferably in a direction to the longitudinal axis of the pressing device 21 arranged parallel flight. Preferably, for each axially juxtaposed printing form 06 or per section a ₁ ; a ₂ ; a ₃ ; a ₄ two pressing elements 112 intended.

In principle, the pressing elements 112 the pressing device 21 all stationary on a printing plate 17 or the printing form to be recorded 06 facing side of the crossbar 111 be arranged so that a placement of the pressing elements 112 solely by moving the crossbar 111 or the transfer unit 18 - A mobility of Traverse 111 provided - overall would be effected. In an advantageous embodiment, however, the pressing elements 112 like that on the crossbar 111 stored so that they with at least one component in a direction perpendicular to the longitudinal axis of the pressing device 21 extending direction are relatively movable. The pressing elements 112 carrying crossbeam 111 itself is preferably room-solid in or on the side frame 04 , ie stored fixed to the frame. In a simple, not shown embodiment, all pressure elements 112 at a common, opposite the Traverse 111 be mounted relatively movable carrier, which by actuation of at least one actuator as a whole along said direction on the forme cylinder 03 is too movable. In a further developed variant, the pressing elements 112 each two adjacent sections a ₁ ; a ₂ ; a ₃ ; a ₄ or the pressing elements 112 each section a ₁ ; a ₂ ; a ₃ ; a ₄ at each common, opposite the Traverse 111 mounted relative movable supports, which is movable in each case by actuation of at least one actuator along said direction. In view of the risk of tilting, however, the present embodiment is of particular advantage, wherein each pressure element 112 mechanically independent of the other pressing elements 112 the pressing device 21 with at least one movement component perpendicular to the longitudinal axis of the traverse 111 is mounted relatively movable. The movement takes place for example via actuators 113 , which in principle can be arbitrarily, for example as motors, based on magnetic forces or acting on pressure means formed. The movement can be done as a linear movement or in the manner of a pivoting movement via a lever arm. In a preferred embodiment, the drive is based on actuators which can be beaten with pressure means 113 , For this purpose, each pressing element 112 a truss-resistant, acted upon by pressure cylinder 114 , z. B. pressure medium cylinder 114 , provided, in which one with the pressure element 112 over z. B. a plunger 116 connected piston is running (or vice versa). In alternative, could be a pestle 116 also act on a lever arm and the bearing on this pressure element 112 pivot. This preferably as a pressure roller 112 trained pressure element 112 is at the actor 113 or on the linearly movable plunger 116 over a bracket 117 rotatably mounted. Preferably, the axis of rotation R112 is substantially parallel to the forme cylinder axis. For this to be ensured, z. B. on the bracket 117 an anti-twist device 118 be provided, for example, as parallel to the plunger 116 extending guide pin may be formed in a traversesfest fitting hole, z. B. a front wall provided in the cylinder bore, dips and thereby adjacent to the plunger 116 a second guide provides against rotation about the ram axis.

By the individual movable storage of the pressing elements 112 tilting and / or skewing and / or slightly different distances can be avoided. The pressing elements 112 the pressing device 21 assigned actuators 113 can do this basically all together or in larger groups, eg. B. in each case those pressing elements 112 two adjacent sections a ₁ ; a ₂ ; a ₃ ; a ₄ , are in operative connection with a same pressure medium supply, ie connected to a same pressure medium line. In this case, the pressure elements connected to the same pressure medium line are 112 Although only all at the same time to control, however, have one degree of freedom in the direction of adjustment. In the preferred embodiment shown here, the one section a ₁ ; a ₂ ; a ₃ ; a ₄ associated pressing elements 112 each of other sections a ₁ ; a ₂ ; a ₃ ; a ₄ independently acted upon with pressure medium. For this purpose z. B. a valve station, not shown, with at least one of the number of independently to be applied pressure elements 112 or groups of pressing elements 112 corresponding number of controllable valves provided, which on its output side via lines not shown with the actuators 113 the respective pressing elements 112 are connected. In this way, at least the individual sections a ₁ ; a ₂ ; a ₃ ; a ₄ or aufwickelnden printing plates 06 attributable pressing elements 112 regardless of those of other sections a ₁ ; a ₂ ; a ₃ ; a ₄ or printing forms 06 to the form cylinder 03 or the printing form 06 can be turned on or off. The pressing elements 112 are as stated z. B. individually or in groups, depending on the application of pressure medium either in one of two positions, namely a rest position (turned off) and a working position (employed), verbingbar. Preferably, the respective pressure element is located 112 without pressure medium, z. B. by spring force, in rest position. The as pressure rollers 112 trained pressing elements 112 are z. B. by a plurality of spaced apart in the direction of rotation axis R112 roller segments 119 or with a plurality of rings arranged next to one another on a roller main body 119 educated.

In the illustrated embodiment of the pressing device 21 This can also be a protection device 121 , z. B. an apron 121 , Which, respectively, an intervention in a between the forme cylinder surface and Andrückvorrichtung 21 formed gap protects. This protection device 121 can either be room fixed with the crossbeam 111 be connected, or in a development with regard. Their distance from the cylinder surface of the form opposite the traverse 111 be stored relatively movable. This can be z. B. by a linear movement by means of a drive provided for this purpose 122 , z. B. at least two also actuated by pressure medium frontal actuators 122 , take place, the linearly movable piston z. B. via a corresponding holder 123 with the - one or more parts - fender 121 connected is.

Is a printing form 06 with its edge of the leading end 09 in coincidence with the opening 07 brought, it is provided in a variant that that of this printing form 06 or this section a ₁ ; a ₂ ; a ₃ ; a ₄ associated pressure rollers 112 by activating their actuators 113 be hired and the intervention of the bent end 09 support. In the following roll then the pressing elements 112 with turning the forme cylinder 03 on the aufzuspannenden printing form 06 and finally carry the trailing end 11 in the channel provided for this purpose 08 , This is then z. B. by activation of a holding means in the channel 08 held. In another embodiment, he is the phase in which the leading end 09 not yet completely in the channel 08 immersed, still no contact with the pressure roller 112 , This is or will be here only to support the winding and to impress the trailing end 11 into the relevant channel 08 used. The risk of breakage in the area of the leading end, preferably bent at an acute angle 09 by possibly violent impressions is thereby reduced.

As drives for this purpose would then, for example, two for radial positions of the roller 26 to consider each end provided actuators. This can for example also be actuated with pressure medium, z. B. be pneumatically or hydraulically acting actuators. A trained in this alternative pressure device 26 is advantageous in a pressure swing system with a transport path 23.2 , whose form cylinder-like section as above for the upper printing unit 02 described runs predominantly vertically.

In principle, the or part of the system components set forth so far 21 ; 26 ; 23 ; 18 ; 17 , z. B. the pressing device 21 ; 26 and / or on the transport path 23 moving transfer unit 18 and / or a correspondingly designed or additionally provided storage device 17 ; 22 in one of the in connection with the feeding and putting on of a new printing form 06 described reverse order and functionality for removing and removing ("plates") a used printing plate 06 Find application. For this purpose, for example, a release of the trailing end 11 on the form cylinder 03 , if necessary Hold down the trailing end 11 or the printing form 06 when unwinding by a pressing device 21 ; 26 , an image of the developed printing form 06 from the form cylinder 03 or from a possibly provided, the unwound printing form 06 acquiring investment facility 19 through the transfer unit 18 and a transport along the transport path 23 ; 23.1 ; 23.2 back to a receiving shaft of a both new and used printing forms 06 provided, or along a z. B. modified transport path 23 ; 23.1 ; 23.2 to an additional for used printing forms 06 provided memory device 17 ; 22 ,

In one by itself, but especially in combination and in conjunction with versions for one or more of the above-mentioned system components 21 ; 26 ; 23 ; 18 ; 17 , is the storage device 22 for receiving used printing forms 06 spatially separated from the storage device 17 for receiving and maintaining new printing forms 06 educated. This has particular advantages in connection with a simple and inexpensive constructed, easy to handle and / or to be transported storage device 17 in an embodiment as a printing plate carrier 17 as described above. The below also as take-back storage 22 designated storage device 22 has this - preferably structurally from the storage device 17 arranged separately - printing forms 06 record memory 124 , z. B. memory slot 124 , which is parallel to the forme cylinder axis and in the axial direction of the forme cylinder 03 considers itself over the entire nominal width W _N of the printing form (s) to be accepted 06 carrying forme cylinder 03 extends. The memory 124 is to accommodate a number of printing forms 06 formed side by side, which is the number m of the maximum on the forme cylinder 03 juxtaposed printing forms 06 equivalent. It may comprise individual sections over the length continuously, but possibly also over webs of small thickness. The memory 124 offers in its width space for at least a number of successively arranged printing forms 06 which is the product of the number of the memory 124 associated printing units 02 and the respective number of circumferentially on the forming cylinders 03 to be placed in succession printing forms 06 equivalent. In the present example, the memory is 124 two each double-trained printing units 02 assigned, so the memory 124 one after the other (at least) four printing forms 06 summarizes. The memory 124 or the storage device 22 can also print 02 two adjacent printing units 01 be assigned.

In the advantageous embodiment shown here is the memory 124 or is the storage device 22 spatially separated from the printing unit 01 arranged such that between memory device 22 and printing unit 01 - At least in an inactive state of the memory device 22 - a free space 126 for lateral access to the printing unit 01 , z. B. a control room 126 for the staff, remains. On the one hand to prevent access and on the other hand a recording of used printing forms 06 to accomplish is the memory 124 or at least one of the printing unit 01 facing front or side wall of the memory 124 movable in a way on a space-fixed frame 127 , z. B. an ehedem provided in the printing press support element 127 or carrier 127 , stored so that it comes from a first position P124.1, z. B. rest position P124.1, in a second position P124.2, z. B. recording position P124.2, can be brought, in which he with his open side 128 , z. B. a loading opening 128 , in the room 126 into and / or in to the printing unit 01 , in particular to a used printing forme 06 transporting transfer unit 18 closer position P124.2. In the rest position P124.1 the memory is running 124 with respect to its height preferably substantially vertically, and thus space-saving.

Moving between the two named positions P124.1; P124.2 can basically be done in a variety of ways by a linear movement and / or a pivoting movement. In a simple, not shown embodiment is the memory 124 - For example, at a height which is below a level of a transfer position P18.3 (Rücknahmesichern) of the cooperating transfer unit 18 is - to a form cylinder axis parallel, spatially fixed pivot axis relative to the frame 127 pivotable. For example, a gift can be given by a rack 127 and memory 124 attacking pneumatically or hydraulically acting actuator

In terms of accessibility of the store 124 by the operator advantageous embodiment of the memory 124 as in 23 and 24 shown by a combination of pivotal movement and translation or linear movement between the positions P124.1 and P124.2 spent. The memory 124 is here in one of the soil 129 nearer area about a form cylinder axis extending parallel, spatially fixed pivot axis S124 relative to the frame 127 pivoted. The pivot axis S124, or a one- or multi-part axis 131 , but is not fixed to the frame, but along a preferably vertical direction of movement T131 translationally in or on the frame 127 movably mounted. This can be z. B. be solved such that an axis 131 or z. B. two short but aligned axes 131 rotatable with the memory 124 connected, but in the frame 127 pivotable and linear along the Movement direction T131 is movably mounted or one or two axes 131 rotatable, but linearly movable in the frame 127 are stored, at which or at which the memory 124 is mounted pivotably via corresponding bearings.

The pivot axis S124 or axis 131 is preferably in the end of one of the loading opening 128 opposite end, z. B. near the ground 129 of the memory 124 which is then moved upwards in a preferably vertical direction of movement T131 when changing from the rest position P124.1 to the loading position P124.2. On one of the loading opening 128 closer than the pivot axis S124 lying height of the memory 124 intervenes with memory 124 and frame 127 each about pivot axes S132.1; S132.2 pivotally connected lever 132 at. The two pivot axes S132.1; S132.2 are spatially related to each other and to the pivot axis S124, so that in the rest position P124.1 of the memory 124 the axis 131 associated pivot axis S124 in one to the printing unit 01 farthest, the between frame 127 and levers 132 effective pivot axis S132.2 in a closer, and between lever 132 and memory 124 Effective pivot axis S132.1 in one of the pressure unit 01 extend the closest vertical plane, wherein the pivot axis S132.1 lies at a height between the other two. Now the axis 131 moved from a rest position P131.1 upwards in a working position P131, so the point of attack deviates between lever 132 and memory 124 (ie the area of the pivot axis S132.1) in a direction to the printing unit 01 out and thus leads the loading opening 128 along a path of movement predetermined by the design and arrangement of the components in the direction of the printing unit 01 or transfer unit 18 ,

The lever length between the linkage of memory 124 and frame 127 as well as the higher of the linkage on the frame 127 are so matched to each other and to the translational travel as well as the height of the memory 124 and the width of the room 126 dimensioned so that through the memory 124 the pickup position P124.1 is reached when the axis 131 has reached its working position P131.2.

The linear motion of the axis (s) 131 in the frame 127 can in principle directly, ie without interposition of a transmission and / or a deflection, by an electric motor acting as a linear motor or a pneumatically or hydraulically acting actuator, or via a transmission such. B. a motor-driven spindle drive or done in any other way. In the illustrated, advantageous embodiment, the drive is via a traction means 133 , z. B. at least one band 133 , a rope 133 or a chain 133 which is at one end 134 stationary, especially on the frame 127 , is attached and via a deflection 136 , z. B. a pulley 136 , led at the ground level area of the store 124 , in particular at or in the region of the axis 131 or the pivot axis S124, attacks. Preferably, the run between the end 134 and pulley 136 and between pulley 136 and memory 124 Zugmittelverläufe substantially parallel and opposite to each other and / or substantially parallel to the direction of movement T131. The pulley 136 is opposite the frame 127 linear, in particular along a direction parallel to the transport direction T131 and / or vertical direction, movably supported and by a drive means 137 movable. For this purpose, the deflection roller 136 either in the frame 127 stored accordingly and over a paddock 138 from the drive means 137 moved, or directly on with the drive means 137 connected paddock 138 be stored. In the illustrated embodiment, the drive means 137 by an acted upon with pressure medium actuator 137 , z. B. a pneumatic or hydraulic cylinder 137 formed, whose associated with the piston plunger 138 as a paddock 138 on an axis of the pulley 136 acts, which in turn linearly movable in the frame 127 is stored.

The memory 124 can as shown - z. B. on the printing unit 01 facing front - one the height of the side boundary or side wall of the memory 124 beyond the extent of at least one of the end faces and / or a rear wall addition extending section 139 , z. B. an extension 139 , which, in the transfer of the used printing forme 06 from the transfer unit 18 to the store 18 the room 126 bridging helps and in the manner of a guide the printing form 06 receives. The extension 139 can basically one-piece and large area, z. B. as a continuation of the front forming sheet. However, it may also be formed in the manner of individual tongues which either continue a sheet forming the front side or a lattice structure forming the front side.

In the following sequence of schematic representations of the 25 is in the nature of snapshots (a to n) in the event that all the system components described 17 ; 18 ; 19 ; 21 ; 22 ; 23 are provided, a total, but also set out in partial sequences advantageous procedure. Reference numerals are for the essential components involved in 25a ), and reproduced in the subsequent sequences only for the changed in terms of their condition components.

25a ) shows the printing unit 01 with her the two printing units 02 assigned form cylinders 03 , Transfer cylinders 12 , the new printing forms 06 upright printing form carrier 17 , the first and second holding elements 63 ; 72 having transfer unit 18 , the lower and with this over the switch 27 connectable upper transport path 23.1 ; 23.2 , with an investment facility 19 with holding elements 106 per printing unit 02 , the roles 112 having pressing device 21 in the lower printing unit 02 and as a pressing device 26 effective roller 26 of the upper printing unit 02 , and a movable memory 124 for picking up used printing forms 06 ,

Based 25a ) to f) becomes the process of detaching one or more printing forms 06 the example of the upper printing unit 02 explained. The printing plate changing system is located in 25a ) already in a phase in which a printing forme 06 from the upper printing unit 02 should be accepted. This was - if the transfer unit 18 not already before this position P18.2 was - the transfer unit 18 by moving on the guidance system 23 into their working position P18.2 (here at the upper printing unit 02 ) spent. The form cylinder 03 is or was spent in a defined for the start of the printing plate change process angle of rotation. In this position is on the forme cylinder 03 the possibly provided holding means in the channel 08 opened in a way, so that the particular trailing end 11 can emerge.

In 25a ) has the trailing end 11 the printing form 06 already the channel 08 leave, where most of the forme cylinder 03 wound printing form 06 z. B. by the roller 26 and / or the first holding elements 63 the transfer unit 18 is supported. The memory 124 may already be in its picking position P124.2 (as shown) or spent. The form cylinder 03 will now -. B. contrary to its production direction of rotation - twisted, so that the printing form 06 unwinds.

In 25b ) became the printing plate 06 by turning the forme cylinder 03 already promoted so far that they are already in the area between transfer unit 18 and contact element 19 located. At this stage the printing form becomes 06 by a holding element 63 ; 72 the transfer unit 18 , in the case of the upper printing unit 02 z. B. the pivotable retaining element 72 , gripped, so that upon further rotation of the forme cylinder 03 and releasing the second pressure forming end 09 the printing form 06 is held. The takeover by the transfer unit 18 can here at a time or a rotational angle position of the forme cylinder 03 take place, to which the pressure forming end 09 is about the channel 08 to leave. After the form cylinder 03 under the printing form 06 was turned away, so the end 09 the channel 08 could leave, are now z. In the case of a non-linear transport path 23.2 the holding elements 72 pivoted in the direction of the subsequent curve, so that the first dissolved pressure forming end 11 without collision with other components of the printing unit 01 along a curved guide section 84.2 can be funded ( 25d )), wherein after passing through this curved portion, the holding elements 72 can be pivoted back to their normal position ( 25e )).

After reaching a printing remote end of the upper transport path branch here 23.2 ie after reaching the switch 27 , the transfer unit can 18 by operating the switch 27 in the transfer position P18.3 for delivery of the printing form 06 to the store 124 be spent ( 25f )). In the event that in the leadership system 23 only one guide branch or two guide branches 23.1 ; 23.1 each with a transfer unit 18 with corresponding adjustment paths of the holding device 62 ; 71 , and therefore no switch 27 is provided or must be, and / or in the event that the currently used leadership branch 23.1 ; 23.2 at the transfer position P18.3 ends (eg here for the lower one) and the switch 27 prolonging this is not moving by means of a switch 27 required. Is the transfer unit 18 Now in transfer position P18.3, so can the holding elements 72 (instead, if necessary 63 ) and the printing form 06 is at the memory in pickup position P124.2 124 be delivered. The memory 124 can subsequently by appropriate actuation of in 25 not shown drive means 137 be returned to his position P124.1.

In the case of a linear guide path 23.1 can picking up the printing form 06 , the holding and dispensing the process described by z. B. alone the first holding elements 63 respectively.

Based 25g ) to n) becomes the process of winding up one or more new printing forms 06 using the example of the lower printing unit 02 explained. First, the printing plate support 17 moved to working position P17.2 (P17.3), which is in 25g ) has already occurred. The first and second retaining elements 63 ; 72 are still out of engagement with aufziehenden printing form 06 , For the case shown here, that first and second (pivotable) holding elements 63 ; 72 are provided, now the second holding elements 72 by pivoting the same with the male (top) printing forme 06 engaged ( 25h )) and activated, so here subjected to negative pressure. Subsequently, the holding elements 72 pivoted back again in druckwerksferner direction, so that a train of the leading edge of the printing form in the holding elements 33 of the printing plate carrier 17 in arises, whereby the printing form 06 undergoes a defined position and orientation and / or a subsequent unhooking of the edge is made possible ( 25i )). Then it will, like 25j ), the printing plate support 17 pivoted back to its rest position P17.1. For the present case, that the pivot axis S17 and the lever length is selected accordingly, slides by the pivoting of the printing plate support 17 the folded leading end 09 by the holding elements 72 ( 63 ) held printing form 06 from the holder of the printing plate carrier 17 , In a modification, this can also be done by moving the transfer unit 18 take place in the transport direction T.

In an alternative case, not shown here, that z. B. only first holding elements 63 are provided are - starting from one to 25g ) comparable starting position - these first holding elements 63 with the male (top) printing form 06 engaged and activated. Subsequently, the printing form carrier 17 pivoted into a second, closer to the rest position P17.1 working position P17.3, so either already hereby or in the subsequent step, a complete unmounting of the edge is made easier ( 25i )). By moving the transfer unit 18 in the direction closer to the cylinder (transport direction T), in this alternative embodiment, the edge is now possibly completely removed from the printing form carrier 17 solved or removed from this. The printing plate carrier 17 then again comparable to 25j ) are pivoted to its rest position P17.1.

The form cylinder 03 is either already in an angle of rotation required for the Aufplatten or is now spent such. Now that's the printing form 06 carrying transfer unit 18 moved to its cylinder-near transfer position P18.2 ( 25k )), where they by lowering, pivoting here, the holding elements 72 ( 63 ) on the investment facility 19 created or even pressed. Equipment The equipment of the facility 19 associated holding elements 106 are now activated, so here subjected to negative pressure, the transfer unit 18 associated holding elements 72 ( 63 ) and lifted or swung away ( 25m )), so that the printing form 06 to the investment facility 19 is passed. An advantageous position in which the printing form 06 at handover with its leading end 09 should come to rest is i above. V. m. 17 and 20 explained. In the embodiment shown here is during transport through the transfer unit 18 already before transfer to the investment facility 19 the printing form 06 through the transfer unit 18 positioned so that the leading end 09 at or in the opening 07 of the canal 08 positioned and / or even at least partially hooked into it ( 25k )).

Finally, with activated holding elements 106 the investment facility 19 the form cylinder 03 rotated in the direction of production while pressing elements 112 a possibly provided pressing device 21 are employed. As a result, the under pressure printing form 06 on the circumference of the forme cylinder 03 wound up until the pressing elements 112 finally the trailing end 11 in the channel 08 press, where they are possibly held there by activating appropriate means ( 25n )).

The above processes for the example of the upper printing unit 02 explained plates and exemplarily at the lower printing unit 02 explanatory Aufplatten are each on the respective other printing unit 02 to transmit, according to the formation of the respective transport path 23 ; 23.1 ; 23.2 (Path form, switch) can be added or omitted individual steps.

One or more of the described system components 17 ; 18 ; 19 ; 21 ; 22 ; 23 and / or sequences, for example at least those as printing plate carriers 17 trained system component 17 and / or a decrease in the printing form 06 from the printing plate carrier 17 and the transport to the form cylinder 03 , are integrated in an advantageous solution in an overall system of printing form logistics, which not only the printing unit 01 associated handling (storage, transport, up / down plates), but also the handling within the printing press or the printing in a functional area 141 the printing form production and / or in a transport and / or logistics system for conveying at least the required for a new production printing forms 06 with z. B. on this coordinated means of transport 151 ; 152 , z.
