the DE 199 35 665 A1 relates to a device for stacking flat goods, in particular metal sheets, on several stacks. The panels are held and conveyed above the displays from above by circulating suction devices, the feed of which can be delayed in the event of a deposit on one of the stacks at the deposit speed.

the DE 20 2010 005 241 U1 discloses an air table for transporting materials, particularly a stack of sheet material. Such air tables would be used to easily transport stacks of paper between processing stations.

through the DE 1 959 928 U discloses an apparatus for sorting, counting and restacking signatures, which includes, inter alia, a shaker table and an air table.

the DE 10 2008 046 125 A1 relates to a sheet processing machine, in particular a sheet punching machine with delivery stations and a method for depositing sheets. There - like in particular the quoted DE 195 16 023 A1 can be seen - to stabilize a large number of blanks stacked next to one another, a full, unpunched layer of sheets is introduced by a stacking aid before the total stack is further increased by a further stacking level.

The invention is based on the object of creating a delivery device for a sheet-fed printing press and a method for delivering sheets of printing material in a delivery device.

The object is achieved according to the invention by the features of claim 1 and 12 respectively.

The advantages that can be achieved with the invention are, in particular, that a safer, uninterrupted stack change with one of upstream installations, e.g. B. a braking device, independent fall height can be done. In particular, it is also possible to support sheets to be transferred at a height that is particularly close to the transport path. This is also of particular advantage in connection with the formation of small stacks, possibly to be further processed inline, and/or stacking without pallets.

Preferably, the flow component projected into the surface of the sheet guide plate and averaged over all directions has at least one non-zero component toward the side edges of sheet B. Another component can be directed in the same direction as transport direction T. That is to say, the air flow leaving the openings 69 is in this case, viewed in the sheet guide plate surface, directed in the same direction—more or less strongly—in the transport direction T in at least one component that differs from zero. At particular points in the sheet path, it may be necessary to use Venturi nozzles which also have a speed component towards the side edges and a further speed component directed against the sheet travel direction or transport direction T.

By suitably controlling one or more of these functional elements, the exact sheet deposit in the relevant delivery station I; II on the one hand and a quality-preserving transfer of the printing material sheets B to be deposited only downstream.

In addition to or instead of this, the at least one braking station 91 of the braking device 48; 49 along the transport direction T moving drive means 63 associated with control means S63, by which the position of the sheet brake 48; 49, in particular the at least one of the sheet brake 48; 49 comprised braking station 91, to which format length L _B of the sheet B currently to be deposited can be adjusted. An optimal position is the exact and damage-free sheet deposit in the relevant delivery station I; II supported.

The control means S63; S106; S107 can be provided in separate control devices or all or in groups in a common control device. They can be part of a higher-level machine control or be provided in a decentralized manner and possibly connected to such.

Depending on whether in the area of the braking device 48; 49 incoming sheets B _n in the directly subsequent delivery station I; II is to be released or passed over it, the drive 106 and/or the switching means 107 are/are one or more holding means 92 of the braking device 48; 49 in two different operating modes m1; m2 operated (see e.g. 22 ). The operating modes m1; m2 can differ in the speed profile for the holding means 92 and/or in a profile for the activation/deactivation of the holding means 92. Operation in one of the operating modes m1; m2 takes place at least for the duration of a cycle length, the cycle length being related, for example, to the machine and/or printing material phase position and z. B. the length of the phase between the entry of the leading end of a sheet B _i and the entry of the leading end 109 of the following sheet B _i+1 into the braking device 48; 49 and/or the length of the phase between the exit of the trailing end of a sheet B _i and the exit of the trailing end 111 of the following sheet B _i+1 from the braking device 48; 49 can correspond.

The decision as to whether in the area of the braking device 48; 49 incoming sheets B _n in the directly subsequent delivery station I; II is to be delivered or passed over it can be taken or be taken by the operating personnel manually or automatically. With the automated decision, this can be based on a measurement or a preset sequence of specimens. For example, so-called waste copies can be attached manually or in a defined number to the relevant stack 11; 12 are given. If several so-called stacks of good sheets are formed, the decision about the assignment of the printed sheets to the individual stacks 11; 12 be or will be taken.

In the event that the delivery device 03 is designed as a double-pile delivery device 03, the drive 106 and/or the switching means 107 of one or more holding means 92 of the braking device 48; 49 in the two different operating modes m1; m2 operated depending on whether the currently incoming sheet of printing material B the first stack 11, z. B. Waste piles, or the other stack 12, z. B. Good sheet stack, or the sheet removal device 87 is to be supplied.

In the advantageous embodiment of the delivery device 03 with several, in particular two, stacks 11; 12 or delivery stations I; II is each of the delivery stations I; II a braking device 48; 49 upstream. Its drive 106 can be operated or is operated in such a way that the active surface 112 of the holding means 92 interacting with the sheets B travels at a conveying speed v32, e.g . B. a speed of the holding devices 32 or gripper carriage speed v32, lower, z. B. at least 50% lower deposition speed v _from operated and / or operable. In a preferred embodiment, its drive 106 can be operated dynamically in such a way that the effective surface 112 of the holding means 92 interacting with the sheet B is at least between the currently present conveying position determined by the conveying system 21 speed v32, e.g. B. a speed of the holding devices 32 or gripper carriage speed v32, and a lower, z. B. by at least 50% lower placement speed v _from continuously variable.

A sheet of printing material B _n to be deposited is fed to the braking device 48; 49 by a holding means 92 of the braking device 48; 49, in particular sucked in pneumatically, which moves at or approximately at, ie at more than 95%, the conveying speed v32, ie without or almost without any relative movement between the holding device 32 of the conveying system 21 and the holding means 92 of the braking device 48, 49 in the direction of transport T moves. After the holding device 32 has been opened, ie for example after the gripper has been opened, the speed v92 of the holding means 92 is reduced by changing the speed to the lower depositing speed v _ab , the sheet B being decelerated as a result and finally placed on the stack 11 .

The reduction in speed or braking that takes place - in particular for the first braking device 48 and the second braking device 49 - for storage in the relevant operating mode m1 takes place preferably along a predetermined curve, the course of which can be changed in an advantageous embodiment and/or can be parameterized via a corresponding input .

The curve or its progression can depend on the current production speed, that is to say on the input-side conveying speed v32 and/or on the nature of the printing material B, and can vary automatically as a function of this.

To correct an incorrect filing and/or to adapt to a new format length L _B , as is the case e.g. B. may be required for a change in production, the curve and / or its course can be changed by operating personnel by varying corresponding parameters defining the curve. In this case, at least the level of the above-mentioned depositing speed v _ab , ie the lower final speed present after the lowering, can be changed by operating personnel.

Instead or preferably in addition to this, the position of the braking device 48; 49 in the transport direction T, in particular the position of the holding means 92, can be changed by the operating personnel.

A sheet B _n+1 that is not to be deposited, ie to be transferred, is also fed to the braking device 48; 49 by a holding means 92 of the braking device 48; 49 was added, in particular sucked pneumatically, which is about, ie a maximum deviation from z. B. at most ± 10%, or preferably at most ± 5%, in particular at most ± 3%, with conveying speed v32, i.e. virtually without relative movement between the holding device 32 of the conveying system 21 and the holding means 92 of the braking device 48, 49, in the transport direction T. However, this state is maintained during the onward transport of the relevant sheet B _n+1 until the sheet B _n with its trailing end 111 hits the braking device 48; 49 has left or is about to leave. The sheet B, which is still held by the holding device 32 of the conveyor system 21, is transported downstream via the braking device 48; 49 directly downstream delivery stations I; II away to another delivery station I; II or a sheet removal device 87 promoted. In order to avoid the formation of waves, the above-mentioned deviation, if any, is e.g. B. at most - 10%, preferably at most - 5%, in particular at most - 3%.

The delivery station I; II, in particular at least the first delivery station I, is thus a braking device 48; 49 assigned or upstream, which operationally can be operated and/or is operated in two different operating modes. This takes place depending on the intended transport destination for the incoming sheet B _i .

In the first operating mode m1, z. B. a storage mode m1, in which one or more sheets B from the first stack 11, z. B. Waste piles are to be stored, the speed of the drive 106 changes per sheet to be stored at least once from a first speed v _in causing speed z. B. as the speed of the incoming sheet essentially - ie with a maximum deviation of ± 10% - corresponds to the above-mentioned conveying speed v32, to a speed causing the deposition speed v _ab and back to essentially conveying speed v32. If several consecutive sheets B _n are to be deposited one after the other, this first operating mode m1 is repeated as often as required so that the braking device 48, 49, i.e. the holding means 92, reduces the speed v92 from the conveying speed v32 to the depositing speed v _and back again in time with the arriving and depositing ones Arc B _n changes.

When changing to delivery speed v _ab , the speed v92 of the holding means 92 during the operative contact with the conveyed sheet B is preferably lowered to a speed v _ab which z. B. at most 50%, advantageously less than 20%, preferably less than 10% of the funding speed is v32. The higher speed v92 of the holding means 92, which essentially corresponds to the conveying speed v32, is above z. B. at least 4 m / s, for example in the range of 4 to 9 m / s, in particular in the range of 5 to 8 m / s. In contrast, the placement speed v _from z. B. at most 2 m / s, for example in the range of 0.5 to 2 m / s, in particular in the range of 0.7 to 1.4 m / s.

The deceleration, ie the lowering of the speed v92 of the holding means 92 from the speed v92, which essentially corresponds to the conveying speed v32, to the depositing speed v _ab takes place, for example, in the sheet path s only in a phase in which the leading edge 109 of the sheet to be deposited B _n+1 ; B _P only less than half an arc length from the alignment s2 to the downstream rear edge of the stack or the front edge 111 of the sheet to be deposited B _n+1 ; B _P is only less than half an arc length away from the escape s1 to the upstream front edge of the stack.

In the second operating mode m2, z. B. a guidance mode m2, in which one or more sheets B over the first stack 11, z. B. Waste piles, or the delivery stations I are to be carried away, the drive 106 over at least the entire phase of contact between the braking device 48, 49, d. H. the holding means 92, and the sheet B to be guided away over the stack 11 or the delivery station I are operated at a speed which causes a speed v92 on the holding means 92 which essentially corresponds to the conveying speed v32. If there is a constant conveying speed v32, this is also at least during the above-mentioned contact phase constant. This second operating mode m2 is basically independent of the presence or the specific execution of a first operating mode, but is of particular advantage in connection with an embodiment of a first operating mode presented here.

In a preferred embodiment of the braking device 48; 49, holding means 92 that can be activated and deactivated in a clocked manner via corresponding switching means 107 are provided. For clocking purposes, switching means 107 has a signal connection, for example, to control means S107, which is designed and set up to activate and deactivate holding means 92 in a synchronized manner and/or in a correlation to a machine and/or printing material phase position Φ. In the case of two operating modes m1; m2, these differ not only in the phase-related speed profile, but also in the switching profile for the wiring, i. H. Activation and deactivation of the holding means 92.

In the first operating mode m1, the holding means 92 is deactivated in the entire or in at least part of the positive acceleration phase from the depositing speed v _ab to the conveying speed v32. In the embodiment as suction elements 92, the suction is stopped at least temporarily in this phase, ie the application of a negative pressure p ^- to the suction element 92 is interrupted.

In the second operating mode m2, the activation of the holding means 92 is maintained over at least the entire phase of contact between the braking device 48, 49, ie the holding means 92, and the sheet B to be guided away over the stack 11 or the delivery station I. The suction or the negative pressure p- is preferably maintained over the entire cycle. In the embodiment as suction elements 92, the suction remains switched on in at least this contact phase, ie the negative pressure p ⁻ on the suction element 92 is maintained. The suction or negative pressure p preferably remains over the entire cycle from the entry of the sheet B _n to ^be transferred into the region of the braking device 48; 49, in particular in the effective area of the holding means 92, until the next sheet B _n+1 enters the area of the braking device 48; 49, in particular in the effective range of the holding means 92, switched on. If several consecutive arcs B _n+1 ; B _n+2 in succession, the suction or the negative pressure p ^- can remain switched on for the duration of the relevant cycles.

With suction over the entire cycle, in particular over the cycles of several sheets to be transferred, it is ensured that the sheet in the second operating mode m2, ie the guidance mode m2, grasps the sheet B _n+1 to be transferred and essentially without relative movement over the to be transferred stack 11, 12 spans. This prevents or at least reduces the sheet B _n+1 to be transferred from “breaking in” into the delivery chute of the stack 11 to be transferred, which allows transfer without loss of quality. This is particularly relevant for productions with high conveying speeds.

Suction air that is permanently switched on in the second operating mode m2 promotes the earliest possible starting and holding of the trailing edge of the sheet B.

For the two operating modes m1; m2 are for example in the control means S48; S49 two different rules for the generation of target values for the speed v92 of the holding means 92 are kept available. The rule ten include, for example, a dependency on the conveying speed v32 and can also depend on other influencing variables and can be parameterized by operating personnel.

The rules each include different assignment rules between the current conveyor speed v32 and a setpoint or setpoint curve for the speed v92 of the holding means 92. For the assignment rule of the second operating mode m2, at least for the duration of the contact with the sheet B, there is a connection with the conveyor speed v32 proportionally correlated course of the holding means speed v92 and for the assignment rule of the first operating mode m1 within at least part of the duration of the contact with the sheet B at least one ramp with a course of the holding means speed v92 falling relative to the conveying speed v32.

When operating the dispensing device 03, for example, in a set-up phase, several, e.g. B. n (n ∈ N), sheets B _i (i = 1 . At least one arc B _n+1 following the n arcs is z. B. as a sample sheet or as a good sheet - in particular using the sheet brake 48 operated in the second operating mode m2 - past the first delivery station I or the first stack 11 and downstream to a further delivery station II or a sheet removal device 87. For example, after a predefined number of set-up sheets have been fed to the first delivery station I as waste and/or, for example, a sample sheet has been found to be good, the system is automatically or manually switched to a production facility in which the sheets B _i are regularly fed in z. B. forming a stack of good sheets 12 are stored. During production operation, however, it can happen for various reasons that one or more sheets _BP —in particular when using the sheet brake 48 operated in the first operating mode m1—have to be fed to the first stack 11 or to the stack 11 representing a waste stack. This can be, for example, exchange sheets that occur when the pile is changed, or faulty or damaged sheets. Such a sheet BP to be _ejected during the production run can be triggered manually or by a sensor system.

To control the at least one drive 106 driving the holding means 92 and/or the at least one switching means 107 activating the holding means 92, the drive 106 and/or the switching means 107 is signal-connected to control means S106; S107, which in turn, for example, in signal communication with a signal generator, z. B. a sensor or a drive master, from which it receives information I(Φ) relating to and/or representing the machine and/or printing material phase position. The control means S106; S107 include a control circuit and/or an algorithm that is set up to control the operating modes m1; m2 explained control of the drive 106 and / or switching means 107 to bring about.

In relation to the execution of the braking device 48; 49 The above also applies to the fact that sheets B _n+1 treated as so-called good sheets are in the first or the second delivery station I; II and sheets B _n treated as waste sheets; B _P in the other delivery stations II; I are to be filed or will be filed. In this case, sheets B _n treated as waste sheets; B _P Setup sheet, defective ejection sheet or sheet after manual decision by the staff must be understood. For example, the waste sheets are or will be deposited on a stack 11 in the area of the first delivery station I and good sheets in the area of the second delivery station II. The above procedure and/or control of the braking device 41; However, 42 can also be provided or used in the reverse assignment of waste and good sheets, as well as in connection with the formation of several stacks of printing material, each of which is different from waste.

The above adjustment of the position of the braking device 48; 49 in the transport direction T, in particular the position X ₉₁ viewed in the transport direction T of the braking devices 91 interacting with the sheets B via the holding means 92, which, for example, represents the variable to be set or, for short, the setting variable X ₉₁ , takes place, for example, via a the desired height or a change that represents the change to be made, which is or can be sent to the relevant control means S63 and is reflected, for example, in a corresponding activation of the drive means 63 .

The position of the braking device 48; 49 or the one or more holding means 92 can be specified as an actuating command directly by operating personnel, in particular by signals σ _FL of one or more operable by operating personnel, in signal connection with the actuator 63 in question, z. B. drive means 63, the Borgen Bremse 48; 49 controlling control means S63 standing actuating means 196; 197; 198; 199, hereinafter also referred to as switching elements 196; 197; 198; 199 or e.g. B. as a button 196; 197; 198; 199 designated net, be given (see e.g. 40 ). The signals σ _FL generated by actuation can directly represent a desired position or a directional change interval. The at least one switching element 196; 197; 198; 199 can be from one of the relevant delivery stations I; II laterally assigned and set up user interface 66; 67 be included.

For manual influence on the situation can for the relevant borrowing brake 48; 49 a switching element 196; 198 may be provided, through the actuation of which the braking device 48; 49 or the holding means 92 is or can be moved to a further downstream position, d. H. can be changed for a format length that is smaller than the current format, and one switching element 197; 199, through the actuation of which the braking device 48; 49 or the holding means 92 is or can be moved to a further upstream position, d. H. can be changed for a format length that is smaller than the current format. With this, for example, both finer corrections can be made and, if necessary, an adjustment to a new format can be made.

The above-mentioned setting of depositing speed v _ab (as variable or setting variable v _ab of drive or drive means 106 to be set) to a desired level is carried out, for example, via a manipulated variable representing the desired level or a directional change interval, which is fed to the relevant control means S106 or can be routed. These are reflected, for example, in a change in the parameters on which the profile is based and ultimately in a corresponding activation of the drive means 106 . This setting can also preferably be carried out by operating personnel (see below).

Instead of or preferably in addition to this manual intervention, the desired position of the braking device 48; 49 or of the holding device(s) 92 and/or the manipulated variable relating to the height of the depositing speed v _ab also by specifying setpoint values _WB , e.g. B. a determined and / or provided for a format to be output parameter set W _B , caused and / or be effected. The latter can be or can be transmitted by a product planning and/or presetting system.

In a preferred embodiment of the delivery device 03, which is the last one in the transport direction T, e.g. B. second pile delivery II and at least one of the last pile delivery II upstream in the transport path, z. B. first pile delivery I, the upstream pile delivery I in the transport path is therefore preceded by a braking device 48 and/or a sheet guiding element 47.4 with variable effective length, with braking device 48 itself or at least an active surface 112 of braking device 48 and /or a downstream end of the sheet guiding element 47.4 of variable effective length of the upstream pile delivery I for depositing sheets B of a first format length LB in a first position P ₁ (48) viewed in the transport direction T; P ₁ (47.4) and for depositing sheets B′ of at least a second format length L _B′ , which is smaller than the first format length L _B , in a second position P ₂ (48), which is further downstream as viewed in the transport direction T; P2 ₍ 47.4); _PS (48); P _S (47.4) can be displaced.

In a first mode of operation, for example, all delivery stations I; II activated, i. H. fundamentally ready for filing conveyed sheet B. The Biogen B in the respective delivery stations I; II depending on the above Control commands to the relevant stack 11; 12; 168; 169 are released or transferred over this, the respective braking device z. B. is operated according to the destination in the first or second operating mode m1, m2.

When the delivery device 03 is operated, which in the transport path of sheets B conveyed by a conveyor system 21 has a last position in the transport direction T, e.g. B. second stack delivery II and at least one of the last stack delivery II upstream in the transport path, front, z. B. first pile delivery I, wherein at least the upstream pile delivery I in the transport path is provided with a braking device 48 and/or a sheet guiding element 47.4 with variable effective length is arranged upstream, i.e. in a first mode of operation the braking device 48 itself or at least one that comes into operative contact with the printing material sheet B Active surface 112 of braking device 48 of front pile delivery I and/or sheet guiding element 47.4 of variable knitting length of front pile delivery I or at least its downstream end in at least a first operating mode of delivery device 03 depending on a current format length L _B , i.e. format length to be stacked; L _{B '} along the transport direction T in different positions P ₁ (48); P1 ₍ 47.4); _P2 (48); P2 ₍ 47.4) positioned.

In a second mode of operation provided in a preferred embodiment, the at least one first and one second delivery station I; II comprehensive delivery device 03 (see e.g. 23 ) is or is this for example during a production or production phase operationally operated in such a way that a - in particular different from a first delivery station I, z. B. downstream last delivery station II is active, i.e. basically ready for depositing sheets B, while another delivery station I - in particular upstream or front of this active delivery station II - is deactivated, i.e. depositing in this delivery station I is neither possible nor intended in this operating state . The basic readiness of the first-mentioned delivery station II can include both continuous depositing and operationally optional depositing or transfer in the above sense. In this mode of operation, the delivery device 03 is not connected to all delivery stations I; 11, but with a reduced number of delivery stations I; II operated. The deactivated delivery station I; II is operationally transferred in this mode of operation through all incoming sheets B, without depositing being possible there by an automatism or a manual setting command.

First, for example, for such a production or production phase with a reduced number of stacks, the delivery station I, e.g. B. the first delivery station I disabled. The deactivation of the pile delivery I in question can be done during the machine configuration for the pending order, i. H. the definition and/or presetting of the aggregates involved in the pending order. This can be done, for example, directly at a control station or at an actuating means connected to it using signals, or it can be done automatically via production data that has been read in.

To displace braking device 48, or at least its effective surface 112, or sheet guiding element 47.4 with variable effective length, or its downstream end of deactivatable pile delivery I, the above-mentioned drive means 63 is provided and preferably a control means S63 with a signal connection to it, which controls braking device 48 or its Effective surface 112 and/or at least the downstream end of sheet guiding element 47.4 of variable effective length of upstream pile delivery I, depending on the mode of operation of delivery device 03, optionally in a first mode of operation depending on a current format length L _B , i.e. format length to be stacked; L _{B '} positioned and for operation in the second mode to a fixed defined support position P ₂ (48); P2 ₍ 47.4); _PS (48); P _S (47.4) shifts, which is preferably located at a location downstream of that position P ₁ (48); P ₁ (47.4), which would have to be provided for the format length L _B currently to be laid out in the delivery device 03 in the first mode of operation.

As already described above, the holding means 92 of the braking device 48 comprises an active surface 112, which can be brought into positive or frictional active contact with an incoming sheet B by activation, whereby the active surface 112 to be brought into positive or frictional active contact with the printing substrate sheet B in at least one operating mode in which an incoming sheet B is to be deposited in the associated pile delivery I, in an advantageous embodiment by a drive 106 forcibly movable in the transport direction T at a variable holding means speed v92.

For operation of delivery device 03 in the second mode of operation of delivery device 03 with a deactivated front pile delivery I, braking device 48 itself or at least one active surface 112 of braking device 48 that comes into operative contact with the printing substrate sheet B and/or a downstream end of sheet guiding element 47.4 of variable active length front pile delivery I to a firmly defined support position P ₂ (48); P2 ₍ 47.4); _PS (48); P _S (47.4), which is at a location downstream of that position P ₁ (48); P ₁ (47.4), which is occupied by braking device 48 or its effective surface 112 or the downstream end of sheet guiding element 47.4 with variable effective length for format length L _B of sheets B currently to be delivered in delivery device 03 in an operating mode with activated pile delivery I. Preferably, this location is downstream of position P ₁ (48); P ₁ (47.4), which would be provided in the first operating mode for the format length L _B of the sheets B currently to be delivered in the delivery device 03.

With deactivated pile delivery I in support position P ₂ (48); P2 ₍ 47.4); _PS (48); P _S (47.4) moves the active surface 112 located at least for the duration of an existing positive or frictional active contact between the conveyed sheet B and the active surface 112 at a speed v92 in the transport direction T, which corresponds approximately to the above, i.e. with a maximum deviation of ± 10%, the current conveyor speed v32 of the conveyor system 21 corresponds.

The support position P ₂ (48); P2 ₍ 47.4); _PS (48); P _S (47.4) can correspond to position P ₂ (48); P ₂ (47.4) correspond, which corresponds to the position to be set for a smallest format length L _B of sheets B to be stored in the first operating mode. That is, the braking device 48 itself or at least one active surface 112 of the braking device 48 that comes into operative contact with the printing substrate sheet B and/or a downstream end of the sheet guiding element 47.4 of variable effective length is adjusted to the smallest format to be designed, e.g. B. minimum format set. In principle, the movement path can still go beyond this setting for the minimum format downstream, with the support position P ₂ (48); P2 ₍ 47.4); _PS (48); P _S (47.4) can then be given by the downstream limitation of the possible movement path.

In an advantageous embodiment, at least one side stop device 103 is set for the second operating mode for the deactivated or to be deactivated stack delivery I. This can be done in a manner explained above.

In the case of movable stop means 83 (see e.g. below) at the upstream end of the conveyor section following the delivery station I in question, these are in the second mode of operation or are moved out of the movement path of the sheets B for the second mode of operation.

In an alternative embodiment for operation in the above second mode of operation with at least one deactivated delivery station I to be transferred can - instead of or possibly in addition to the above-mentioned Positioning of the braking device 48 or its holding means 92 and/or the sheet guiding element 47.4 - a shortening of a free length of the sheet guiding gap can take place or be provided by other mechanical support means. This can for example be a sheet guiding element which z. B. by the correspondingly raised support device 36; 37 itself a sheet guiding means arranged on this, e.g. B. baffle is formed. For example, for the second mode of operation in the delivery station I in question, the carrying device 36; 37 by vertical positioning in a transport path near, z. B. highest possible position spent. In addition to this, beforehand, during or after this position has been reached, a said sheet guiding means can be or be used.

As already indicated, the run-on section 78 has a run-on bevel with preferably a rounded edge 84, in particular an upper edge 84, in the region of its upstream end. For this purpose, the conveyor system 21 facing, substantially flat guide surface 79 of the run-on section 78 is in a downwardly bent, z. B. rounded contact surface 81 continued. In addition to actually flat surfaces, the essentially flat guide surface 79 should also include slightly curved surfaces with a radius of curvature of z. B. continuously at least 1,000 mm, in particular at least 3,000 mm. The rounding of the edge 84 is z. B. in such a way that the edge 84 is rounded in such a way that a course of the upper side viewed in a vertical section running in the direction of transport between a first point lying in the region of the still flat or slightly inclined guide surface 79 to a second point , at which an inclination of the tangent to that at the first point is 45°, has at least a radius of 50 mm and/or that a course of the edge 84 between the end of the flat or at least essentially flat guide surface 79 and a course perpendicular to the course calculated at a distance of 50 mm from this point in the approach surface 81 at each point a radius of curvature of at least 5 mm, preferably at least 10 mm, and preferably a maximum radius of curvature of z. B. 500 mm, in particular 200 mm. The radius of curvature does not have to be constant in the section under consideration, but can vary. A leg that may include the rounded contact surface 81 mentioned above can, in principle, be continuous, partially interrupted or multi-part in the transverse direction, i.e. in the direction of the width of the dispensing device (see e.g. 8th ). In the following, the term "planar guide surface" is intended to include the above-mentioned case of a slightly curved surface.

The upper corner area of the approach section 78 is to be understood here as the “edge” 84 of the approach section 78 in the above sense, regardless of whether it is z. B. by the rounded corner of a solid component or z. B. is formed by a bent down metal sheet.

Stop means 81 of a stop device are preferably provided in or in front of the vertical alignment of the contact surface 79 and below the height given by the guide surface 79, which limit the movement in the transport direction T for the sheets B to be deposited in the first delivery station I. The downstream stack edge of the stack 11 to be formed is formed on these stop means 82 . In addition to this, movable stop means 83 can be provided which are driven by a drive device 64 with at least one drive means 99 in a first, e.g. B. active operating state on the given by the guide surface 79 height and in a second, z. B. inactive operating state are arranged below this level. In a less complex embodiment, several of the stop means 83 can be moved or can be moved together via a connection or shaft, for example. The contact section 78 can have air passage openings 68; 69, in particular blast air openings 69 or blast air-operated air passage openings 69.

In a first preferred embodiment of the approach section 78, this comprises in the region of the rounded edge 84, ie in an upstream connection with the planar guide surface 79 the curved surface section 84, a blower device with one or preferably more blower air openings 97. The blower air openings 97 can be formed by round or preferably slot-shaped recesses 97 in a material section 84, in particular sheet metal section 84, forming the rounded edge 84 and can be be supplied with blown air on the side of the material section 84 facing away from the transport of the printing material. The blown air supply can be formed by an air box adjoining the material section 84 on the inside.

In a preferred embodiment, the blown air supply is formed by a blown air line 98 running in the transverse direction on the inside of the material section, the wall of which in turn comprises outlet openings arranged corresponding to the blown air openings 97 . The blown air line 98 is preferably formed with a shape corresponding to the inside of the material section, at least in the region of its side facing the material section 84 . For example, the air blast line 98 is designed as a blow tube with a circular outer peripheral cross section and the material section 84 is designed arcuate in cross section, at least in the region of its section opposite the air blast line 97 . The blown air openings 97 provided in the material section 84 have a larger opening cross section than the outlet openings, at least in a direction running in the direction of movement of the printing material sheets guided over the approach section 84 . This ensures, for example, a safe passage of air.

In a particularly advantageous development, the blown air line 98 , which is preferably designed in the form of a tube, can be mounted such that it can pivot about an axis running in the transverse direction. In this way, the position of the blown air outlet along the direction of sheet movement can be adjusted at least slightly, particularly in the case of blown air openings 97 that are larger than the outlet openings in the above manner.

The start-up section 78 designed in this way can, in principle, be configured independently of the design of the delivery system 03 with a plurality of delivery stations I; II may be provided in the region of the start of a conveying path comprising sheet guiding elements. However, this is preferably at the beginning of one between two delivery stations I; II arranged conveyor line provided.

The sheet B, which is guided only at the front edge by the conveyor system 21 or the holding device 32, in particular the holding elements 56, is usually lowered into the chute of the delivery station I that has passed over it; II until it is in equilibrium with the natural air cushion that forms on the underside. The continuation of the sheet guidance on a predominantly horizontal guideway can at the end of the overrun delivery station I; II - lead to a harmful level jump, especially in certain operating situations with, for example, a low stack level. In this case, the natural air cushion is not able to move the sheet B like a wing over this step onto the following sheet guiding element 47.5; 78, in particular stop plate 78 to lift. Especially at higher speeds, the underside of the sheet B can hit and cause damaging contact.

The possible effects can be avoided or at least mitigated by one or more of the aforementioned measures (rounding off and/or air blast). Instead of these measures or in addition to one or more of the measures mentioned, in a particularly advantageous embodiment, delivery device 03 and/or sheet guiding device 47 and/or a delivery station I; II directly downstream sheet guiding element 47.5; 78, in particular a run-up section 78 comprised by or upstream of a sheet guiding element 47.5, this or at least its guide surface 79 facing the guided sheet B is designed and/or supported with at least its upstream end in a variable vertical position. In particular, this sheet guiding element 47.5; 78 or this start-up section 78 can be varied in its vertical position by means of a controllable drive means 283 .

At least the upstream end of the run-up section 78 is height-adjusted to the variable stacking level, i. H. the height of the top sheet B in stack 11; 12, adjustable. Preferably, this end is automatically adjustable in height to the variable stacking level, in particular via control means. For this purpose, the drive means 283 included in the actuator, in particular its control unit or drive regulator, is signal-connected to a control means that adjusts the vertical position of at least the end of the sheet guiding element 78 as a function of and/or correlated to the stack level.

The setting or the variation takes place at least within an operationally provided setting range, which extends from an upper layer L ₀ in which, in the production run, with a stack 11 already partially formed; 12 of a minimum height without any further variation in the height of the run-up section 78 until the target stack height is reached, down to a lower layer L _U , in which z. B. is stored in production at the beginning of the stack formation (see e.g. 9a ) and c ). The latter is approached, for example, when the time of the process of the stacking table 36; 37 is to be used at least in part until the working height assumed for the production run is reached and/or if the working height, ie the level of the uppermost layer of sheets ideally to be taken in the above-mentioned production run, at the beginning of stack formation, due to a limited adjustment path for the stacking table 36; 37 is not achievable with low stack heights. Between these two layers L _O ; L _U located layers L _Z (see e.g. 9b ) can in principle be or will be approached stationary in other special operating situations, but are or will regularly be on the way between the two other positions L _O ; L _U only run through dynamically. The adjustment range between the upper and lower position L _O ; L _U is, for example, at least 50 mm, preferably more than 100 mm. In principle, positions that go beyond these two limits (position L _O and position L _U ) can be approachable on one or both sides, which, however, can be approached, for example, for set-up or maintenance work or other non-operational activities.

The start-up section 78 is designed and/or mounted due to the aforementioned variability in such a way that, even for levels that are reduced compared to the maximum pile level or that assumed during production, the currently present pile level can be compared with the sheet guiding level that is higher for this case, preferably horizontal, i. H. the level specified by the course of the conveyor system. Here, the "stack level" is to be understood as the vertical position of the upper end of the stack.

A motor 283, in particular an electric motor 283, is provided as drive means 283, for example. B. via a gear 284 directly or indirectly on the sheet guiding element 47.5; 78 or start-up section 78 engages. A spindle drive 284 can advantageously be provided as the gear 284, the threaded spindle 286 of which, driven by the motor 283, is connected directly or indirectly to the sheet guiding element 47.5; 78 or the contact section 78 connected bearing block 287 engages. In principle, the drive for varying the position can be effected from just one side by just one actuator with motor 283 or also from two sides by one actuator with motor 283 each. In an advantageous embodiment, the positioning is carried out by an actuator with only one motor 283, but from two sides. For this purpose, gears 284 acting directly or indirectly on both sides are provided, for example, on the start-up section 78, the movement of which is mechanical, e.g. B. via a shaft 291 is synchronized. The two synchronized drive trains of the actuator are driven by a motor 283 at some point, for example on either side.

The sheet guiding element 47.5; 78 or the sheet guiding element 47.5; 78 varying in the vertical position drive means 283 can be manually adjustable, for example, using operating elements not shown here. Instead or advantageously in addition to this, the sheet guiding element 47.5; 78 or the sheet guiding element 47.5; 78 in the vertical position varying drive means 283 preferably automatically adjustable via control means, preferably - at least in an operationally provided adjustment range or a sub-area - correlates to the vertical position of the stack top in the upstream stack space 44; 46 adjustable. In operation, the vertical position of at least the upstream end of the approach section 78 is thus correlated to the vertical position of the top of the stack in the upstream stack space 44; 46 varies. The vertical position of the upstream end or the drive means 283 can be controlled, for example, as a function of information representing the position of the top side of the stack. Instead of or in addition to this, the vertical position of the upstream end or the drive means 283 can be used in conjunction with and/or correlated to the control of the vertical position of the stacking table 36; 37 be controllable and/or controlled.

A sensor system set up for this purpose can be provided, for example, to provide information representing the position of the top side of the stack. Their output signals or results processed from them are z. B. fed to the control means or can be fed to them. For example, a distance sensor can be provided above the stack 11, 12 or else in the upstream end face of the approach section 78 a sensor system that detects the upper edge of the stack.

Sheet guiding element 78 is preferably arranged and/or mounted in delivery device 03 in such a way that, if the vertical position of the upstream end of sheet guiding element 78 varies within the operationally intended adjustment range, the respective upstream stacking space 44; 46 end face of the sheet guiding element 78 facing perpendicularly counter to the transport direction T come to rest on a substantially vertical line. The "essentially vertical line" should also include a line that actually runs in a straight line vertically as well as a line that runs straight or constantly or varyingly curved with a maximum deviation of 5° from the vertical, the minimum radius of curvature of which is twice the length of the transport direction T of the Sheet guiding element 78 corresponds. What this course of the lines has in common is that the in of the respective vertical position in each case directed counter to the transport direction T and thus also the position of the first contact by an accumulating sheet B does not change significantly in the horizontal direction, despite vertical variation.

This essentially vertical positioning of the upstream end is effected by an actuator which acts directly on or at least near the end to be moved on the run-on section 78 and displaces the run-on section 78 at the point of action along a vertical rectilinear movement.

In an advantageous embodiment, the sheet guiding element 78 or the z. B. also known as a stop plate 78, in an advantageous embodiment, the stop section 78 is designed and/or mounted in such a way that the vertical level of the guide surface 79 supporting the sheets B at the downstream end remains the same when the vertical position of the upstream end varies. However, against the background of the guide element dimensions, this should allow for negligible deviations in the range of a few millimeters, e.g. B. of up to 5 mm. By maintaining the level, a transition to a subsequent section or sheet guiding element 47.5 can be kept virtually stepless in the above sense, regardless of the vertical position of the upstream end.

In the event that the above If the height of the upstream end is varied along the above-mentioned, essentially vertical line and the level at the downstream end is maintained, a guide device is provided with a stop means 288 fixed to the frame, which is provided with a stop section which is fixed, in particular in one closer to the downstream end than to the upstream end stop means 289 provided closer to the area of the approach section 78 for the defined assumption of position of the downstream end of the approach section 78 cooperates.

The stop means 288; 289 are designed in such a way that when the upstream end varies vertically along the essentially vertical line and the associated horizontal movement of the downstream end, the effective guide surface 79 in the transition area to the sheet guiding element 47.5 following downstream maintains the level in the above-mentioned manner. This includes z. B. at least one of the stop means 288; 289 a correspondingly shaped stop cam, on which the corresponding stop means 289; 288 supports. For example, the frame-fixed stop means 288 includes such a curve on which the z. B. as a roller 289 designed starting section fixed stop means 289 runs along. The stop means 289 which is fixed to the approach section can be supported from below by the stop means 288 which is fixed to the frame. - gravity ensures a secure contact. Conversely, the stop means 289 fixed to the approach section can be pressed from below against the corresponding stop means 288 fixed to the frame. In this case, this can be effected either statically via a spring element acting on the contact section 78 or via a drive means, by which z. B. the corresponding stop means 288; 289 are selectively brought into contact with each other and out of contact. In the embodiment with an embodiment presented below of a stop section 78 that can be pivoted with the downstream end in the event of a fault, the stop section 78 acting on the stop section 78 and responsible for the contact between the corresponding stop means 288; 289 providing drive means may be formed by the pivoting causing drive means 104.

The start-up section 78, which can be varied in its vertical position in this way, is preferably at the beginning or at the upstream end of one between two delivery stations I; II arranged conveyor line provided. A preferably horizontally running section of the same sheet guiding element or a preferably horizontally running further sheet guiding element 47.5 can be connected to the downstream end of the approach section 78. In a further variant, the sheet guiding device on the between two delivery stations I; II lying conveyor line with the upstream end of the start-up section 78 ends.

The approach section 78, also known as the approach plate 78, can be in several parts, e.g. B. be formed from several adjoining baffles. The guide contour of the approach section 78 can be made up of flat and curved sections. In an advantageous embodiment, the contact section 78 in the area of the guide surface 79 and/or in the area of the bent edge 84 comprises the above-mentioned Air passage openings, in particular blowing air openings 69; 97 has. For this purpose, the start-up section 78 z. B. supplied with blown air.

In addition to the above-mentioned blowing device and/or the vertically variable design of the upstream end of the run-up section, or on its own, in a further advantageous embodiment or variant of a run-up section 78, the above-mentioned stop device can be designed in such a way that a plurality of stop means 83; 86 individually or at least in several groups by an ent A number of drive devices 64 or drive means 99 that can be moved, e. B. pivotable or z. B. are translationally movable.

To move all, a group or preferably the individual stop means 83; 86, the drive means 99 can in principle be of any design. However, it is preferably designed as a cylinder-piston system 99 that can be pressurized with pressurized fluid, in particular as a pneumatic cylinder 99 .

The groups or individual stop means 83; 86 moving pneumatic cylinder 99 can in principle be switched via a common switching valve and / or supplied with compressed air. Preferably, however, for each of the groups or individually to be moved stop means 83; 86 each have their own switching means 101, in particular switching valves 101, or valves 101 for short, to which compressed air is applied on the input side, for example, and to which the applied compressed air can be switched through to the output side via corresponding control signals and the relevant pneumatic cylinder 99 can be acted upon via a line connection.

Basically, the groups or preferably individual stop means 83; 86 via the drive means 99 associated switching means 101 or valves 101, for example in the form of a valve terminal, can be combined centrally at one point. In a preferred embodiment, however, the switching means 101, in particular valves 101, are arranged in a decentralized manner and/or at least in groups or preferably all at a spatial distance from one another, in particular in each case close to the associated pneumatic cylinder 99. The switching means 101 or valves 101 are arranged, for example, closer to the assigned pneumatic cylinder 99 than to the or one of the other pneumatic cylinders 99. However, they are at least arranged closer to the assigned pneumatic cylinder 99 than half the distance between the two pneumatic cylinders that are furthest apart 99

Valves 101 are switched, for example, in a synchronized manner and/or in a correlation to a machine and/or printing material phase position by control means S83 (S86) of a control device, which is in signal communication with a sensor or a master, for example, from which it receives the machine and/or information I(Φ) relating to and/or representing the printing material phase position. The stops can then be brought into the active position, for example, exactly in a gap between two incoming sheets of printing material B. If the sheet travel is known and/or constant, a dead time compensation, for example, can be carried out by means of precontrol.

The control means S83 (S86) can be part of a higher-level machine control system or can be provided in a decentralized manner and possibly connected to such a system.

The switching of the stop means 83; 86 occurs e.g. B. depending on whether a sheet of printing material B in the upstream delivery station I; II filed, or should be further promoted to another delivery station II or a sample sheet removal.

In the case of the above-mentioned blower device integrated in the area of the edge 84, for example, a blower air supply is activated and deactivated depending on whether a sheet of printing material B is in the upstream delivery station I; II filed, or should be further promoted to another delivery station II or a sample sheet removal.

In an advantageous development of the approach section 78, blast air openings 69, in particular in the form of Venturi nozzles 69, are provided in the guide surface 79 and/or in the surface of the sheet guiding element 41.5 that continues the guide surface 79.

In a first embodiment, for example, pivotable stops 83 can be provided as stop means 83 . The movable, in particular pivotable, stops 83 can be integrated into the upstream end of the approach section 78 and/or arranged on it. Here, the guide surface 79 z. B. recesses 102, in which the trained example in the first embodiment stops 83 can be lowered in the inactive state.

In the embodiment with a vertically variable upstream run-up section end, this stop device with pivotable stop means 83 can then be arranged fixed to the frame or vertically movable together with the run-up section end.

Furthermore, in a variant not shown here of the stop device comprising the pivotable stop means 83, mechanical holding devices can be integrated in the structural unit of the stop section 78, which hold down printing material sheets B that have already been placed in the upstream delivery station I, while subsequent printing material sheets B go to a further delivery station II or to a sampling point be transferred. Such a holding device is z. B. in the event of an intended renewed filing of another sheet B on the stack 11, 12 of the upstream delivery station I at least for the time required for this purpose from the path of movement of the sheet B removable. Such a holding device can prevent sheets B that have already been deposited from being carried away, or at least make it more difficult.

When filing change from the first to a following stack 11; 12, e.g. B. a stack of waste on a stack of good sheets, the necessary for storage on the first stack 11, the sheet B catching stop means 83 are brought out of the path of movement of the sheets B in order to be able to transfer sheets of printing material B, e.g. B. good sheets, to have a free passage space available. However, the problem can arise that -. B. despite an optionally provided blowing device - the last just deposited sheet B, which may form a still provided with air pockets "buoyant" ream and by the fluid mechanical forces of the z. B. designed as a gripper carriage 32 holding devices 32, which promote the sheets B at full speed, a drift arises, which can lead to the ream or individual sheets B being entrained at the end.

In order to be able to counteract this, one or more stops 83 - as in the first embodiment described above - be designed and movably mounted in such a way that they are in the active state, i. H. are in an active position in the path of movement of the printing material sheet B and this side facing the leading ends of the sheet, z. B. a stop surface, are effective as a front stop, and in the inactive state, d. H. in the inactive position, the sheet of printing material B arriving from the path of movement is moved out, that is to say they are arranged outside the path of movement, and are without a stop effect for the sheet of printing material B arriving. In addition to this, one or more of the movable stop means 83 is assigned a holding means 299, which is forced to move along with the movement of stop means 83 and, in at least one inactive position of stop means 83, protrudes beyond the stop surface in the direction of the incoming printing substrate sheets B holds back the uppermost sheet of printing material B in the region of its downstream edge from being lifted off and entrained by sheets of printing material B to be transferred. When the assigned stop means 83 is in the active position, holding means 299 preferably comes downstream and/or above the path of movement of the printing material sheet B to be delivered to stack 11, and when the assigned stop means 83 is in the inactive position below the path of movement of the printing material sheet B to be conveyed further over stack 11 to lie over the top sheet of printing material B of the stack 11.

When the stop means 83 is inactive, the holding means 299 assigned to the stop means 83 thus holds the top layer of the stack 11 down against it being lifted off and/or being entrained by sheets of printing material B to be subsequently transferred. B. with a maximum of a slight distance, be spent in physical contact with the top stack layer. A maximum slight distance can e.g. B. correspond to a length with which, viewed in plan view, the holding means 299 in the holding position and the stack outline at the downstream end of the stack 11 in the transport direction T overlap.

In a preferred embodiment, the assignment of the holding means 299 can be realized in such a way that an upper part of the stop means 83 in the inactive position encompasses the holding means 299 reaching upstream over the edge of the stack. Alternatively, a holding means 299 could be connected rigidly or via a mechanical coupling to stop means 83 in such a way that movement of stop means 83 forces the required movement of holding means 299 to take place and/or vice versa, movement of holding means 299 triggers the relevant movement of the stop means 83

Stop means 83 is preferably embodied in the active position as a stop 83 that serves as a front stop for the approaching sheet of printing material B, which - particularly in the region of its upper end in the inactive position - for holding down the topmost stack layer as holding means 299 raises and rises upstream above stop surface 302 with the outline of the stack at its downstream end at least as a holding means 299 overlapping projection 299 in the manner of a holding finger bent upstream. The projection 299 or holding finger used for holding down can also be referred to as a cover mark 299 .

In the embodiment of the stop means 83, in which they also include the holding means 299, the sheets of printing material B to be deposited, e.g. B. Waste sheets, against this movable stop means 83 or stops 83 at. If the printing material sheet B is conveyed further, e.g. B. good sheets over the stack 11 away, z. B. to a subsequent delivery station II, these stop means 83 are moved from their lying in the movement path "catcher position" in a lying outside of the movement path retracted position, with the holding means 299 or cover marks comprised by the stops 83 299 hold down the top stack sheet to prevent it being carried along and/or slipping.

Basically, the movement of the stop means 83 can be done by pivoting, where z. B. contrary to the embodiment set out above, the pivoting to take the retracted position does not take place downstream, but in the upstream direction. The stop means 83 pivoted upstream can hold down the uppermost sheet of the stack, for example. The movement can also take place on any other movement path, provided that the stop means 83 and the holding means 299 associated therewith assume the positions defined above.

In an embodiment preferred here, however, the stop means 83 is arranged and/or mounted in such a way that the stop means 83 comprising the holding means 299 is moved in a straight line, in particular on a substantially vertical line, i. H. a direction deviating from the vertical by a maximum of 5°, in particular by a maximum of 2°, preferably by a maximum of 1°. Preferably, the movement of the stop means 83 is guided, so that the or at least one point of the holding surface facing the sheet B to be held is subject to an exact linear guidance.

The stop means 83 is preferably arranged and/or mounted in such a way that the holding means 299 can be moved during the retraction movement in the entire operational setting range, which, for example, B. ranges from an upper layer, in which an incoming sheet B is or should be caught, to a lower layer, in which an incoming sheet B can pass and the upper stack sheet is held down, the stack layout in the region of the downstream end of the stack never leaves completely, d. H. always one of the above Overlap between holding means 299 and stack outline remains. The retraction movement ends, for example, in contact or at least - in the above sense - close to contact with the top sheet B of the stack 11.

As already explained above, in order to move all, a group or preferably the individual stop means 83; 86, the drive means 99 can basically be designed as desired, but is preferably designed as a cylinder-piston system 99 that can be pressurized with pressurized fluid, in particular as a pneumatic cylinder 99.

The above-mentioned can be applied or applied correspondingly to pressurize the pneumatic cylinders 99, to the number and position of the switching means 101, in particular switching valves 101, and to control them via control means S83 (S86) of a control device.

The driving means 99 effecting the movement, e.g. B. the pneumatic cylinder 99, can in principle act directly on the output side on the stop means 83 comprising the holding means 299. Preferably, however, the stop means 83 is driven via a gear, e.g. B. via a gear that increases the travel of the drive means 99 . In an advantageous embodiment, this transmission is designed as a coupling transmission, which can be shifted in particular quickly. For example, this is designed as a straight-line gear based on an isosceles crank. For this purpose, the stop means 83 to be moved, viewed in its direction of movement, acts in at least one point with a guide 297, e.g. B. linear guide 297 together, so that the stop means 83 at least at the level of this point is linearly guided movable or is moved.

In principle, a point of the stop means 83 that is spaced apart in the direction of movement could also be linearly guided by the same or another linear guide 297 . A gear member 292, e.g. B. a coupler 292 on. At a distance from this pivot axis 301, another gear member 296, e.g. B. a crank 296 on the coupling 292. The crank 296 is attached to a frame 303 about one of the first two pivot axes 301; 298 parallel pivot axis 304 pivotably mounted. In a preferred embodiment, the axis between the first two pivot axes 298; 301 effective length of the coupler 292 between the second and third pivot axis 298; 304 effective length of crank 296.

In principle, any suitable drive mechanism can be used for the pivoting drive of the crank 296 or the crank-coupling system, for example a direct rotary drive of the crank 296 or a drive means 99 acting on a point of the crank 296 at a distance from the pivot axis 304. In these cases, the The aforementioned guidance of the stop means 83 on two spaced apart ones in the direction of movement is advantageous.

In the embodiment preferred here, a multiple coupling or a coupling that extends significantly in the direction of movement with the linear guide 297 can be dispensed with by the coupler 292 when the crank 296 moves in a distanced from the second pivot axis 298 kop fixed point of attack is forced onto a defined movement curve. The coupling-fixed second point of application can in principle be in the two first pivot axes 298; 301, but is preferably located in a section 307 that continues the connection section beyond the second pivot point 298 in a different, in particular opposite direction to the effective direction of the connection section or as a lever arm rigidly connected to the coupler 292 and, independently of this, is referred to below as the section 307 that lengthens the coupler 292 .

Preferably, the coupler 292 is in this spaced coupling-fixed point via a guide 294, z. B. linear guide 294, in a straight line, in particular perpendicular to the direction of movement defined by the linear guide 297 and to the first two pivot axes 298; 301 running trajectory, forced. The coupler 292 or the section continuing this is in this spaced-apart coupler-fixed point via a likewise to the first and second pivot axis 301; 298 parallel further, e.g. B. fourth pivot axis 306 pivotally mounted.

As mentioned above, the drive center 99 could in principle act directly on the crank 296, but here it preferably acts on the coupling 292, in particular on the section 307 that lengthens the coupling 292. The attack takes place z. B. also to the first and second pivot axis 301; 298 parallel further, e.g. B. fifth pivot axis 308 between second and fourth pivot axes 298; 306. The drive preferably acts on the coupling 292 or the section 307 extending the coupling 292 at a distance from the second pivot axis 298 which is less than half the distance between the first and second pivot axis 301; 298 corresponds. These length ratios enable a translation of a short drive center stroke into a large actuating movement.

The attacking on the stop means 86 transmission can - such. Am 14 and 15 shown - be designed and arranged such that the pivot axes 298; 301; 304; 306; 308 perpendicular to the transport direction T. However, as an alternative to this, it can also be designed and arranged rotated by 90°, so that the pivot axes 298; 301; 304; 306; 308 run in the transport direction T.

Although the design of the delivery device 03 and/or sheet guiding device with a sheet guiding element 78 connected to the delivery station with an end whose vertical position can be varied, and the design of the delivery device 03 and/or sheet guiding device with the stop device comprising the holding means 299 also stand alone are to be used advantageously, their combined design offers particular advantages with regard to the safe and gentle transport of the printing material sheets B (see e.g. 11 , 12 and 13 such as 14 ).

For example, shows 11 the upstream end of the sheet guiding element 78 in the upper position L _O , while the stop means 83 comprising the holding means 299 is in 11a) in the position L _A active for striking and in 11b) is in holding position L _H. The representations in 12 and 13 show the same facts, but in 12 with in lower position L _U and in 13 with sheet guiding element end 47.6 in an intermediate position L _Z ; 78

In an advantageous development, the approach section 78 can be moved in this way in or on a spatially fixed frame G or frame part G of the delivery device - fundamentally independently of the above-mentioned type and design of the stop movement or vertical variability at the upstream end and/or the specific drive design of the stop means 83 03 so that it can be removed from the position assumed in the operating position and thus removed from the sheet transport path present in the operating position - preferably downwards. Although it could also be mounted for linear movement for this purpose, it is preferably mounted so that it can be pivoted downwards out of the operating position about a pivot axis A78 running transversely to the transport direction (see e.g. 25 a) and 25 b) . The pivoting z. B. by means of a drive means 104, which is preferably designed as a cylinder-piston system 104 that can be actuated by pressurized fluid. Preferably, the drive means 104 moving the start-up section 78 can be connected to and controlled by control means S78 with regard to its activation via a signal connection, which in turn can be controlled, e.g. B. via a signal connection 107 with a - especially optical - sensor 108, z. B. a photo sensor 109 is connected. Irregularities in sheet travel, in particular crumples and possible jamming of an incoming printing material sheet B, can be detected by this, for example via a corresponding signal evaluation. The control means S78 can be set up and/or designed to react to a signal curve of the sensor system 108 which indicates a fault in the printing material flow, in particular a Crumple, close, automated to generate a moving away, in particular pivoting, the approach portion 78 causing signal and the drive means 104 forward.

It is preferably moved out or pivoted away in such a way that the downstream end of the sheet guiding element 78, which is preferably designed as a run-up section 78, is or is moved further out of the transport path present in undisturbed operation, in particular further downwards, than the upstream end.

The stop means 83 mentioned above are preferably structurally integrated in the approach section 78 or the movably mounted sheet guiding element 78 . In the latter case, these z. B. when moving the sheet guiding element 78 moves with this.

In the area of the first and/or second delivery station I; II at least on one side, preferably on both sides of the movement path of the sheets B, there is a device 103 serving as a stop for the sheets B laterally, or side stop device 103 for short, which in the relevant delivery station I; II sheet B to be deposited serve as a lateral path limit for the exact alignment of the stack edge (see, for example, in 5 ). Such a side stop device 103 preferably comprises stop means 201 (see below) that can be moved laterally, ie in the direction of the stack width running transversely to the transport direction T, which enable fine adjustment and/or adaptation to varying format widths of the sheets B.

The sheet guidance and / or controlled filing on the stack 11; 12 is - as already indicated above - in a preferred embodiment by a device 51; 52 supported. This can be the case for an embodiment with only one delivery station I for this delivery station I, for an embodiment of a delivery device 03 with two or more delivery stations I; II for one of these delivery stations I; II or for several or all of these delivery station I; II be of particular advantage and applicable.

Above the transport path above the delivery station I; II arranged blowing device 51; 52 comprises a plurality, e.g. B. Number o (with o ∈ ℕ, o > 1) of blowing devices 113q (q ∈ {2,3, ... o}) extending in the transverse direction, which are preferably designed as so-called blowing tubes 113q, in particular transverse blowing tubes 113q and in one embodiment variant can have one or more chambers in sections. For example, at least five (o ≥ 5) or preferably more than 7 (o > 7) here z. B. ten (o = 10) blowing devices 113q provided.

The blowing devices 113q, which extend in the transverse direction, can each be extended by a blowing device extending in the transverse direction - via z. B. at least half the maximum printing material width continuous - be formed flat jet nozzle.

Preferably, the blowers 113q extending in the transverse direction are each separated by a group 113q of transverse, i. H. transverse to the transport direction T, blowing elements 114r provided next to one another. The group 113q includes e.g. B. a number p (with p ∈ ℕ, p> 1), air blast openings 114r, in particular air blast nozzles 114r (r ∈ {2,3, ... p}) and extends z. B. over at least the two middle quarters of the maximum printing material width. There are, for example, at least 8 (q≧8) or preferably more than 12 (q>12) per blowing device 113q, here z. B. sixteen (q = 16) blowing ports 113q provided. The group 113q of blown air openings 114r is preferably formed by a blast tube 113q having the blown air openings 114r.

The number o of blowing devices 113q extending in the transverse direction can in principle all be combined with regard to the supply of blowing air and/or wiring. For this purpose, all blower devices 113q can then be activated and deactivated via a common switching means 116, for example.

Advantageously, however, the blower devices 113q can be activated or deactivated independently of one another, individually or in groups of several, using a plurality of switching means 116 . In the case of several upper groups, for example, several neighboring groups 113q or blowing devices 113q are combined.

At least one switching means 116 is preferably provided for each blowing device 113q, by means of which the respective group 113q or a subgroup thereof can be activated, ie can be acted upon with blowing air that is under overpressure. In a particularly fast-reacting embodiment, several blowing devices 113q, e.g. B. two subgroups of blown air openings 114r are provided, which can be switched, ie activated and deactivated, via a number of switching means 116 corresponding to the number of subgroups. In a particularly fast-reacting and in this respect preferable embodiment, for several or all of the blower devices 113q for the left and the right half of the blower air openings 114r of the blower device 113q, in particular the z. B. two-chambered blast tube res 113q, a switching means 116 that can be switched independently of the other switching means 116 is provided.

The switching means 116 are designed as electronically switchable slides 116 or rotary slides 116 or preferably as electronically switchable switching valves 116, valves 116 for short. Compressed air is applied to these on the inlet side, for example, which can be switched through to the outlet side via corresponding control signals and—via a line connection—can be applied to the relevant blowing device 113q. Although the switching means 116 are referred to as valves 116 in the following, what has been said can basically also be applied to other designs.

A pressure profile falling from the inside to the outside, i.e. the profile in the force effect K (see e.g. diagrammatically 29 ) on the sheet B, a line leading the blown air from the respective switching valve 116 to the blower tube 113q preferably opens out within a central longitudinal section, e.g. B. within the length of the two inner quarters, in the blasluft-leading interior of the blower tube 113q. In the case of two switching valves 116 or feeds to the blower tube 113q, this applies to both, it being possible for the interior of the blower tube 113q to be divided by a wall in the region between the two feeds.

A plurality or all of the blower air openings 114r of the blower device 113q can be assigned an unspecified adjusting means, by means of which the blower air flow and thus also the pressure profile can be adjusted and/or varied. These can be screw plugs, for example, which protrude into a line cross section of a line channel leading to the blown air opening 114r, and the position of which allows the opening cross section for the flow to be varied. Desirable here is, for example, a pressure profile that falls outwards in terms of the force effect, it being possible for the specific shape to depend on the printing material and/or the conveying speed v32. A desired adjustment of the pressure profile can also be realized without further adjusting means by the position of the blown air supply in the blast tube 113q, by the position and size of the blown air openings 114r and by the choice of the free cross section or a varying course.

In principle, the individual supergroups, groups 113q or subgroups 113q1; 113q2 of blast air openings 114 associated valves 116, for example in the manner of a valve terminal, can be combined centrally at one point. In a preferred embodiment, however, the valves 116 are decentralized and/or at least in groups or preferably all spatially spaced apart from one another, in particular close to the associated upper group, group 113q or subgroups 113q1; 113q2 arranged. The valves 116 are, for example, each arranged closer to the inlet 121 into the associated blower tube 113 than to the inlet into the or another blower tube 113. However, they are at least arranged closer to an inlet 121 into the associated blower tube 113 than half the distance between the the two blower air nozzles 114 of the associated blower tube 113 that are farthest apart.

The supply of the blowpipes 113q, ie the upper groups, groups 113q or in particular sub-groups 113q1; 113q2 or the valves 116 arranged upstream of them takes place from a source 119 via a blown air path, which can be formed by serial and/or parallel line paths. For example, a line coming from a compressed air source can open out into a line 117 running transversely to the transport direction T, which is formed, for example, by a hollow transverse traverse 117 or is integrated into such a transverse traverse. From the transverse line, a passage can be made into at least one longitudinal line 118 running parallel to the transport direction T, e.g. B. longitudinal distributor 118, which can be formed by a hollow running, longitudinal beam 118 or integrated in such a longitudinal beam. In an advantageous embodiment, two such hollow longitudinal supports 118 can be provided for guiding the blown air. Branches 122 for supplying the upper groups, groups 113q or, in particular, subgroups 113q1; 113q2 or the valves 116 upstream of these. A branch is preferably assigned to each of the blower devices 113q designed as blower tubes 113q. The source 119 can also be a compressed air source 119 provided for other applications of the machine 01.

In an advantageous embodiment, in the line path from the source 119 to those of a supergroup, a group 113q or subgroup 113q1; 113q2, an actuator 124, e.g. B. a pressure control valve 124 is provided. The pressure to be switched downstream via the valve 116 can be adjusted and/or varied by means of this actuator 124, preferably remotely and/or automatically. If a same group 113q or a same blowpipe 113q several, z,. For example, if two valves 116 and inlets 121 are assigned, the valves 116 assigned to this same group 113q can be supplied with blown air via the same branch and via a common actuator 124 .

At least one such actuator 124 can be provided for each upper group or preferably for each group 113q or for each blower tube 113q. A profile for the blowing effect along the transport direction T can thus be adjusted and/or varied.

For example, the pressure can be regulated by the actuator 124 to an outlet-side pressure of between 0.6 and 1.8 bar, in particular between 1.0 and 1.5 bar. In an advantageous embodiment, an overpressure of 1.2±0.1 bar is present on the outlet side of the pressure control valve 124 and/or on the inlet side of the switching valve 116 . In a preferred embodiment, when activated, i. H. open valve 116 in the downstream blow pipe 113q a pressure P greater than 0.6 and 1.8 bar, in particular between 1.0 and 1.5 bar, preferably 1.2 ± 0.1 bar. When switching means 116 is activated or when valve 116 is opened, air flows at least briefly at a pressure greater than 0.6, in particular between 1.0 and 1.5 bar, in particular at a pressure of approximately 1.2. i.e. H. 1.2 ± 0.1 bar, stagnant air as blown air from the blown air openings 114r. The transverse blower tubes 113q and the blower air openings 114r are thus supplied or pressurized with compressed air at a pressure greater than 0.6 bar, in particular between 1.0 and 1.5 bar, preferably 1.2±0.1 bar. The pressure given here is the overpressure compared to normal pressure, i. H. compared to 1.013 bar.

In the line path from the source 119 to the valves 116, in particular to the longitudinal distributor 118 arranged upstream of the valves 116, an adjusting means 123 limiting the pressure of the source 119, in particular a pressure reducer 123 limiting the pressure of the source 119, can be provided. For example, a maximum pressure of 2.0 bar on the outlet side, e.g. B. in the range from 1.0 to 1.5 bar, in particular from 1.2 ± 0.1 bar providing pressure reducer 123 is provided or the pressure reducer 123 is operated accordingly.

Irrespective of whether pressure control valves 124 are provided, a blowing device 51; 52 provided, the input side with compressed air at a pressure greater than 0.5 bar, z. B. a pressure between 0.6 and 1.8 bar is supplied or is. The blowing device 51; 52 is on the input side thus with a compressed air with a pressure greater than 0.5 bar, z. B. a pressure between 0.6 and 1.8 bar, providing compressed air source 119 in line connection. In the case of sufficiently large line cross-sections up to the blast air openings 114r, in the activated state of the relevant valve in the blast tube, i. H. on the inner side of the air blast port 114r, air blast at approximately the same pressure, i. H. a pressure greater than 0.6 bar, e.g. B. a pressure between 0.6 and 1.8 bar.

In a preferred embodiment of the blowing device 51; 52, in particular in connection with an arrangement above a first of several delivery stations I; II, the blowing devices 113q - arranged one behind the other in the transport direction T and extending transversely to the transport direction - are activated and deactivated individually or in upper groups depending on the intended transport destination for the sheet B _i entering the delivery station I, so that only those in the area of this Delivery station I sheet B to be deposited are applied from above with blown air.

In principle, the blowing devices 113q or blowing tubes 113q running transversely can be activated and deactivated together depending on the transport destination. This could take place via a common switching means 116, which is controlled by a control device comprising control means S116.

In a preferred embodiment, the blower devices 113q or blower tubes 113q are activated and deactivated for the sheet B to be deposited, synchronized with the advance of the sheet B to be deposited. The blower devices 113q or blower tubes 113q are synchronized, for example, with regard to the point in time and the duration and/or in a correlation to a machine and/or printing material phase position Φ, i. H. clocked to the printing material flow, activated and deactivated. For example, the blower devices 113q or blower tubes 113q can be switched on successively for a sheet B to be deposited, starting with its front edge. With a corresponding number and arrangement of the blowing devices 113q or blowing tubes 113q - in relation to the length of the blowing device 51; 52 central transport section - for each sheet B, several blowing devices 113q or blowing tubes 113q can be activated or switched on at the same time, whereby after the entry of the sheet B into the effective range of the blowing device 51; 52 successive blowers 113q or blower tubes 113q are activated or switched on and the number of blowers 113q or blower tubes 113q acting on the sheet B increases as the sheet B progresses, until z. B. the end of the sheet B or a leading end of a subsequent sheet B to be transferred into the effective range of the blowing device 51; 52 occurs.

If several overlapping sheets B are to be deposited one after the other, the blowing devices 113q or blowing tubes 113q remain z. B. to the passage of the last sheet to be deposited B or entry of a leading end of a follow activates the sheet B to be transferred. In the case of sheets B overlapping in the printing material flow, the blower devices 113q or blower tubes 113q are only deactivated again, for example one after the other, starting with the front edge of a first sheet B to be transferred.

In the case of a stream of sheets overlapping in an imbricated manner, the blower device remains continuously inactive for a series of sheets B to be transferred.

For the alternative case of sheets B being conveyed without overlapping, the blower devices 113q or blower tubes 113q activated for the sheet B to be deposited can be successively deactivated again by sweeping over its rear edge. Depending on its transport destination, the next sheet B is then either activated again successively or transferred with the blowing device 51 inactive; 52 performed.

The air blast openings 114r of the blower tubes 113q, in particular transverse blower tubes 113q, are or will be activated and deactivated individually, in groups or as a whole depending on the respective transport destination, i.e. whether the incoming sheet B is to be deposited or transported further, in such a way that only the in the delivery station I below, sheets B to be deposited are subjected to blown air.

Optimization and, if necessary, regulation of the pulse generated by the blown air, which is correlated with the transport speed, takes place, for example, via the pressure control valves 116 mentioned.

For transport destination-dependent and/or successive wiring, i. H. Activation and deactivation of the switching device(s) 116 are associated, for example, with the above-mentioned Control means S116 with a signal connection, which are designed and set up to activate and deactivate the switching means 116 and/or select an operating mode for operating the blower device 51; 52 depending on the transport destination of the delivery station I; To bring about II incoming arc B. Instead or in addition to this, the control means S116 are designed and set up to activate and deactivate the switching means 116 in a synchronized manner and/or in a correlation to a machine and/or printing material phase position Φ. A distinction can be made between two modes of operation, with a first mode of operation relating to a sheet B to be deposited and a second mode of operation relating to a sheet B to be transferred. In the first mode of operation, the blower devices 113q or blower tubes 113q are activated simultaneously or successively, in the second mode of operation at least the blower devices 113q or blower tubes 113q that are above the sheet B to be transferred are deactivated during the transfer.

The switching means 116; 138 and/or adjusting means 124; 128 controlling control means S116 can be part of a higher-level machine control or be provided decentralized and possibly connected to such.

The control means S116 are preferably in signal communication with a signal transmitter, e.g. a sensor or a drive master, from which they receive information I(Φ) relating to and/or representing the phase position of the machine and/or printing material.

In principle, the previously mentioned blowing devices 113q, in particular embodied as blowing tubes 113q, can also extend in the transport direction and be arranged in a plurality transverse to the transport direction T next to one another. With a corresponding arrangement of the blower tubes 113q and the blower air openings 114 provided in them, a similar pattern of blower air outlets can then be implemented if necessary. However, there is no variability in the direction of transport T in terms of time and/or the strength of the effect, or not to the same extent as in the case of the transverse blower tubes 113q.

However, in addition to the plurality o of blowing devices 113q or blowing tubes 113q extending transversely to the transport direction T, at least one blowing device 126 extending in the transport direction T, e.g. B. a so-called. Blow pipe 126, in particular longitudinal blow pipe 126, may be provided which extends in the transport direction flat jet nozzle or a plurality of z. B. as blast air nozzles 127 formed blast air openings 127. The at least one z. B. as a blower tube 127, in particular as a longitudinal blower tube 127 running blowing device 27 is, for example, in the middle of the transverse to the transport direction T width of the underlying and / or stack 11 to be formed; 12 arranged. Thus, when activated, this blowing device 127 supports the depositing, which initially takes place in the middle. Activation or deactivation is also carried out here by a switching means 138 controlled by the control means S116 and arranged upstream of the blower tube 126, which is designed as an electronically switchable slide 138 or rotary slide 138 or preferably as an electronically switchable switching valve 138, or valves 138 for short.

The at least one longitudinal blowing device 126 can be supplied via a line connection from the same source 119 - possibly via the the same or a further pressure-limiting adjusting means 123; 128, e.g. B. Pressure reducer 123; 128, take place. With or without upstream actuating means 128, an actuator 129, e.g. B. a pressure control valve 129 may be provided. In the longitudinal blowing tube 126 there is preferably blown air with a higher pressure than the blowing air of the transverse blowing tubes 113q, e.g. B. a pressure of at least 4 bar, preferably at least 5 bar. Due to the central arrangement and the high pressure, sheets B can be stiffened by “breaking” in the middle for the purpose of sheet deposit.

The at least one longitudinal blower tube 126 is or is activated and deactivated according to a pattern comparable to the transverse blower tubes 113q, also depending on the respective transport destination, in such a way that only the sheets B to be deposited in the delivery station I below are subjected to blower air.

In addition to the plurality o of blower devices 113q or blower tubes 113q extending transversely to the transport direction and, if necessary, instead of or in addition to a longitudinal blower device 126, a fan system 131 that supports the lowering of the sheets B - particularly in the area of low conveying speeds - can be provided. This comprises, for example, one or more rows of fans 132, in particular axial fans 132, which are arranged next to one another in the transverse direction over the transport path and which can preferably be regulated individually or in groups with regard to their performance. For example, two rows of eight fans 132 each are combined on a common frame as a so-called fan cartridge 133 . In addition to this, the blowing device 51; 52 or the fan system 131 one or more rows of further fans 134, in particular axial fans 134, z. B. arranged on a common support frame 136 which can be moved in the delivery device along the transport direction T. For example, a row of seven fans 134 is combined on the common support frame 136 as a so-called fan bar 137

In particular in connection with the design of the delivery system 03 as a multiple-pile delivery 03, in particular a double-pile delivery 03, the blower unit 51 is designed and set up to selectively apply blower air to individual sheets B or a series of sheets B arriving from a stream of a stack and the remaining sheets B to let the archery relay pass without being applied.

The described blowing device 51; 52, individual sheets B, in particular those to be deposited, can be provided with a strong impulse in a targeted manner. This enables depositing even at high conveying speeds v32 and/or a high sheet frequency. By deactivating the blowers 113q; 126 for sheets B to be transferred, these are not subjected to air and thus receive no impulse. As a result, the possibly disrupted run of the sheet B to be transferred does not become unnecessarily even more restless and contact with the stack underneath can be avoided.

If the blown air is only activated in a clocked manner for individual sheets B to be deposited, the energy expenditure can be significantly reduced compared to permanent blowing.

In an embodiment that is advantageous with regard to the stacking quality of the first stack 11, the or a part of the blower air openings 114r, which are provided one behind the other in the transport direction T and are to be activated independently of one another, in particular each comprising a plurality of blower air openings 114r, are or are transverse blower devices 113q or blower tubes 113q, in an operating phase of the above second mode, in which z. B. one or more sheets B entering the first delivery station I are to be or are to be transferred according to the first operating mode, are subjected to blown air or activated and deactivated in such a way that they only - at least for a time interval or temporarily - enter the gap between successive sheets B, in particular in the gap between the trailing end 11 of a sheet B and the holding device 32 of the following sheet B _n ; B _n+1 , in particular the gripper carriage 32 transporting the following sheet B. As a result, the top sheet of the transferred stack can be acted upon at least temporarily in order to prevent or at least make it more difficult to lift off.

In this operating situation, the blower devices 113q or blower tubes 13q located above the sheet B to be transferred and moving in the transport direction T are or will be deactivated, but as the sheets B advance, they will be or will be for a time window over a gap between consecutive sheets B, in particular in a gap between the trailing end 11 of a sheet B and the holding device 32 of the following sheet B, lying blowing devices 113q or blowing tubes 113q are successively activated for at least one time interval lying within this time window.

The valves 116 assigned to the blower air openings 114r or blower devices 113q, which can be activated one after the other independently of one another, are signal-connected to a control means S116, which in turn is signal-connected to a signal transmitter that supplies information I(Φ) relating to and/or representing the phase position of the machine and/or printing material and is designed and set up for this purpose, activation of the blown air via valves 116 as a function of the phase position relating to the machine and/or printing material and/ or representing information I(Φ) in such a way that blowing takes place only within a gap between two consecutive sheets B that are not to be deposited.

For example, a sheet B _n to be transferred--which in this example can be a first or any one of a series of sheets B to be transferred--is transported over the stack 11, while the blowing devices 113q or blowing tubes 113q above are inactive. One or more above the gap between the trailing end of this sheet B _n and the leading end 109 of the following sheet B _n+1 , or in particular a holding device 32 receiving it at the leading end 109, moving in the transport direction T as the sheets B advance, are successively activated and deactivated again at the latest when the leading end 109 of a next following sheet B _n+2 or, in particular, a holding device 32 receiving it at the leading end 109 arrives.

For this purpose, control means S116 are provided and set up to activate and deactivate the switching means 116 assigned to the blower devices 113q or blower tubes 113q in a synchronized or clocked manner and/or in a correlation to a machine and/or printing material phase position Φ. The control means S116 can be embodied mechanically as a rotary slide or as a cam switch mechanism that switches individual valves 116 or as a controlled control means S116 that actuates the individual switching valves 116 electronically.

A further development is advantageous according to which a number of blowing devices 113q blowing simultaneously into the same gap varies or can vary with the format length of the printing material sheets B. For example, for a longer format, a first number of consecutive blown air openings 114r or blast devices 113q are used to blow into the gap (see e.g. 30 a) until 30 c) ) while for a shorter format with a higher number of consecutive blown air openings 114r or blast devices 113q, the blown air is blown into the larger gap (see e.g. 30 a) until 30 c) .

In a development, the effect of the blower devices 113q or blower tubes 113q can be adjusted in terms of their width and/or position viewed transversely to the transport direction T. For this z. B. external sections can be permanently deactivated or deactivated, in particular turned off or turned off. For example, individual blast air openings 114r can be closed by an actuating means that is not detailed

Together with one or more design features of the above sheet guiding device 47 and/or the braking device 48; 49 and/or to the blowing device 51; 52 and/or to approach section 78, or considered on its own, a particularly preferable device 139 for releasing the conveyed sheets B, or release device 139 for short, comprises a switching device for releasing conveyed printing substrate sheets B with an actuating device 143, by which the release in area of the associated delivery station I; II can be selectively activated and deactivated, and with an actuating device 144, through which, viewed in the transport direction T, the location X ₁₃₉ of the sheet release, in the case of holding elements designed as grippers 56, is called the gripper opening point location X ₁₃₉ , in the area of the associated delivery station I; II can be set or varied. The two adjusting devices 143; 144 are here by independently operable actuators 146; 147, e.g. B. drive means 146; 147 adjustable. The release device 139 is thus designed to activate or deactivate the switching device 141, 142, in particular to engage or disengage switching means 141; 142 of z. B. mechanical switching device 141, 142 to effect.

An embodiment of the delivery device 03 that is particularly advantageous in this context has a conveyor system 21 comprising at least one holding device 32, through which a sheet of printing material B can be picked up and transported downstream to a delivery station I; II can be conveyed, where it can be released from the holding means 32 and delivered to a stack 11, 12 to be formed, or can be further conveyed downstream. It further comprises a switching device 141, 142 which brings about the delivery and which has one of the delivery station I; II includes functionally and/or spatially assigned switch cams 141 and a cam follower 142 functionally and/or spatially assigned to holding means 32, cam follower 142 acting—directly or indirectly—on at least one holding element 56 of holding device 32 in order to actuate it.

Although the cam follower 142 is basically also slidable with the shift cam 141 together could act, it is preferably designed as a roller lever 142 and interacts with a roller comprised by the cam follower 142 with the switch cam 141 .

The switching cam 141 can be switched to the undisturbed, d. H. movement path 152 of the cam follower 142 can be moved in and out again, in particular pivoted, without switching cam 141. In this case, the pivoting preferably takes place about a pivot axis A141 that runs perpendicularly to the transport direction T and is fixed to the frame with respect to a spatially fixed frame G of the delivery device 03.

To vary the transport route-related location of the release to be effected by the switching cam 141, a contact point 151 for the initial contact between the switching cam 141 and the cam follower 142 to be moved in the transport direction T is provided on the switching cam 141--e.g. B. within at least one considered in the direction of transport, in particular effective as a control section longitudinal section - can be varied by a different from the first actuating device 143 second actuating device 144 acting on the switching cam 141.

The “cam follower” 142 is to be understood as meaning any type of stop element 142 which, when it comes into contact with an active surface 149 of a cam 141, in particular a switching cam 141, executes a movement that follows the shape of the interacting active surface 149 and—possibly via a transmission element 59, e.g. B. the gripper shaft 59 - on the member to be actuated, here z. B. at least one holding element 56 acts. On the other hand, a “switching cam” 141 is to be understood in general terms as any type of structural unit providing the effective surface 149 as a stop surface. In the case of a cam 141 that is movably mounted during operation, for example, a multi-part and jointly movable structural unit with a component comprising the active surface 149 and a holder carrying this component—possibly detachably—should also be understood.

The switching cam acting as a release cam is on a side facing the movement path 152 of the cam follower 142 in at least one longitudinal section viewed in the transport direction T and acting as a control section with an active surface 149, e.g . B. contact surface 149 executed.

Due to the two separate actuators 143; 144 satisfies the requirement for precise adjustability on the one hand and the fastest possible insertion and removal on the other. This enables operation with high precision and a high conveying rate or production speed, for example with a sheet flow of more than 12,000 sheets per hour (B/h), in particular more than 15,000 B/h.

To vary the contact point 151 of the first contact, the switching cam 141 can be varied in a preferred embodiment with at least one of its ends related to the transport direction T, here advantageously the upstream end, in its distance from the movement path 152 of the cam follower 142, i. H. it can be brought, for example, in the region of this end by a movement with at least one movement component perpendicular to the transport direction T closer to the movement path 152 and further away. For activation or deactivation, at least the other end of switching cam 141 relative to transport direction T can be varied in its distance from the movement path of cam follower 142 such that in a first operating position it dips into undisturbed movement path 152 of cam follower 142 and in a second Operating position is completely removed from the path of movement 152 of the cam follower 141.

For this purpose, the first adjusting device 143 acts on a first point of action P143 of the release cam 141 and the second adjusting device 144 on a second point of action P144 spaced apart in the transport direction T.

Here, the switching cam 141 by the second actuator 144 z. B. can be pivoted about a second pivot axis A144 lying in the point of action P143 of the first actuating device 143 . The second pivot axis A144 or the first point of action P143 can be radially displaced by the first actuating device 143 and/or the first drive means 146, in particular pivotable about a pivot axis A141 that is fixed to the frame with respect to a spatially fixed frame G of the delivery device 03.

The first actuating device 143 includes a liquid or gaseous pressure medium F, z. B. pressurized fluid F, operated and / or operable first drive means 146, z. B. a hydraulic or preferably pneumatic cylinder 146. To supply the drive means 146 with pressure medium F, a switchable valve 153 and at least one fluid line 154; 156 is provided, the line path of the or at least one fluid line 154; 156 between an output of the valve 153 and an input into the drive means 146 preferably at most the maximum width, esp special at most half the maximum width in the delivery station I; II corresponds to the sheet of printing material B to be stacked. In this way, dead times and scatter caused by compressibility can be kept as small as possible.

The control of the valve 153 takes place, for example, via control means S146, the z. B. implemented as part of a machine control in this or can be provided in a different control device S141.

In an advantageous embodiment, the hydraulic or preferably pneumatic cylinder 146 is double-acting, i. H. can be acted upon with pressure medium in both directions.

Due to the double-acting design and/or the arrangement of the valve close to the drive means, a switching drive that acts particularly quickly and precisely is created.

By, for example, two fixed end positions being defined and/or definable in the drive train of the first actuating device, switching cam 141, i. H. a quick and precise activation and deactivation of the release device 139 is possible.

The second actuating device 144 preferably includes an electric motor 147 for driving it. The electric motor 147 is actuated, for example, via control means S147. To supply the drive means 147 with electrical power, there can be a line connection (not shown in more detail) to a power unit.

In an advantageous embodiment, the electric motor 146 acts on the output side of a threaded gear and, together with the latter, forms an electromotive linear drive.

In an embodiment that is advantageous, particularly for delivery devices 03 for sheets of printing material B with a large maximum width, the delivery station I; II On both sides of the arc path, ie in the area of both side frames of the frame G, a switching device 41, 42 as described above is provided. Each of the two switching devices 41, 42 is preferably assigned its own first actuating device 143, each with a first drive means 146 and a switching means 153, in particular a valve 153. The actuating movement is synchronized, for example, electronically.

In principle, each of the two switching devices 141, 142 can also be assigned its own second actuating device 144, each with a drive means 147. In a robust and inexpensive solution, however, the second adjusting devices 144 are e.g. B. via a shaft 157 running transversely to the transport direction, in particular synchronous shaft 157, mechanically synchronized with one another and preferably driven by a common drive means 147, in particular a common electric motor 147.

The first point of action P143 or the second pivot axis A144 can be pivoted about the pivot axis A141 fixed to the frame using any type of lever which can be pivoted about the pivot axis A141 fixed to the frame and the pivot axis A143 to be pivoted or the starting point P144 to be pivoted eccentrically by a lever length to the frame-fixed swivel axis A141. This lever can be connected in a rotationally fixed manner to a shaft which is rotatably mounted in the frame G and can be pivoted by the drive 146 about the pivot axis A143 fixed to the frame.

In a preferred embodiment, a one- or two-armed lever 158 is pivotably mounted on an axle 159 fixed to the frame, on which on the one hand the drive means 146 or an output-side transmission member 161, z. B. the piston rod or a linkage connected to it, attacks. On the other hand, the first attachment point P143 or the second pivot axis A144 is articulated on this lever 158 offset by the eccentricity e in relation to the pivot axis A141 fixed to the frame. This can be done via an axle or shaft stub 162 mounted on the lever 158 . The pivoting then takes place via a lever 158 designed as an eccentric lever 158 over a lever length e given by the eccentricity e. In an advantageous embodiment, where the second pivot axis A144 to be pivoted runs within the axial cross section of the axis 159 defining the pivot axis A141 fixed to the frame, a particularly robust arrangement for mounting the first point of application P143 or the second pivot axis A144 is created.

In a particularly advantageous embodiment, the activation/deactivation is carried out by moving the switching cam 141 in or out with the aid of an eccentric lever 158, which is or is actuated by a double-acting pneumatic cylinder 146, which is supplied in particular via a switching valve 153 close to the drive means.

The pivoting of the second point of action P144 or the first pivot axis A143 about the second pivot axis A144 can in principle take place via any type of gear mechanism on which the second drive means 147 engages on the drive side.

However, one embodiment is particularly advantageous which, in addition to at least one single-armed or multi-armed lever 163; 164 comprises a coupler 162 articulated in both ends. In an advantageous and illustrated embodiment, the drive means 147 acts on a lever 162 which is non-rotatably mounted on a shaft 147, e.g. B. above synchronous shaft 147 is arranged. By means of a further lever 164 arranged in a torsion-proof manner on the shaft 157, the drive takes place indirectly or directly via a joint on the coupling 162 and via a further joint directly or indirectly on the second point of application P144.

In an advantageous development, the first adjusting device 143 is designed in such a way that the lever 158 in an operational end position of the switching cam 141 introduced into the movement path 152 for activation in the region of a dead center close to the movement path, i. H. viewed in a projection plane about the pivot axis A141 perpendicular to the pivot axis A141 on a line lying at most 30°, in particular at most 20°, from the line of the shortest connection between pivot axis A141 and movement path 52. As a result, forces that are introduced into the construction by the impacting cam follower 142 are at least predominantly conducted into the bearing and, at most, react to a small extent on the drive.

In order to control the drive means 146, which moves the control cam 141 either into the movement path 152 of the cam follower 142 or completely out, and/or a switching means 153 that switches the drive means 146, the latter has a signal connection to a control means S146, which in turn has a signal connection to a machine and /or information I(Φ) relating to and/or representing the printing material phase position and is designed and set up to activate and deactivate drive means 146 and/or a switching means 153 that switches drive means 146 in a correlation to a machine transmitted by a signal generator - To bring about and/or printing material phase position Φ.

In order to control the drive means 147 that varies the switching cam 141 with regard to the delivery location and/or a switching means that switches the drive means 147, this has a signal connection to a control means S147, which in turn has a signal connection to information I (Φ) supplying signal transmitter and is designed and set up to cause drive means 147 and thus the gripper opening point to be set in a correlation to a machine and/or printing material phase position Φ transmitted by a signal transmitter.

For high production or conveying speeds, the infeed and outfeed movements should be able to reach the other effective switching state as quickly as possible, e.g. B. be completed within at most 150 ms, preferably within 130 ms.

For this purpose, an adjustment movement on both sides, if necessary, does not take place via a mechanical synchronization, but preferably via respective drive means 146. Instead of this or in addition to this, delays at the end of the action due to the shortest possible line paths are advantageous, as is the case, e.g. B. with the short fluid lines 154; 156 set out above. Alternatively or in addition to the above advantageous restriction of the length of the line path, the length of the respective line is selected such that the dead volume enclosed in the respective pressurized supply line is no more than 25% of the volume stored in the extended cylinder, which is given, for example, by the piston cross-section multiplied by the piston stroke of the extended cylinder is. In a particularly advantageous embodiment, this dead volume is less than 10%. In a further development, in which the valve 153 is mounted directly on the cylinder 146 or even integrated into the cylinder 146, this value can be reduced to less than 5%, in particular to less than 2%.

In order to minimize control-based dead times, the control means S146 controlling the deactivation/activation are equipped with fast switching logic, i. H. a switching logic, with a signal relating to the machine and/or printing material phase position of an above-mentioned Signal generator without delay directly, i. H. in particular, it is not only processed and transmitted via clocked processing, such as that which takes place in PLCs and possibly clocked bus systems, to form a signal σ147 that controls the drive means 147 or triggers the activation or deactivation. The rapid switching logic thus switches the adjusting device 143 activating and deactivating the switching device 141, 142 with machine angle accuracy.

Instead or in addition to one or more measures for minimizing the dead time, a dead time compensation can be provided, preferably dependent on the machine speed. B. over inertia still existing dead time compensated by appropriate pre-control. In this case, for example, the machine and/or printing material phase position correlated with the possible switching time can correspond to the considered dead time moved forward or be. In a preferred development, the degree of advancement can be varied depending on the transport speed, so that, for example, at a higher speed the triggering machine and/or printing material phase position is shifted further forward than at a lower transport speed. It is thus possible to have the actual movement of switching cam 141 always begin in the same or at least essentially the same machine and/or printing material phase position for different machine speeds or revolutions per minute.

Although the switching device 141, 142 described in only one to form stacks 11; 12 trained delivery station I; II comprehensive delivery device 03 can be provided, whereby in the area of the delivery station I; II sheets B that are not to be delivered can be routed, for example, to a sample sheet removal or a collecting container for receiving waste, it is preferably in a a plurality of to form stacks 11; 12 trained delivery station I; II comprehensive delivery device 03 provided.

To activate and deactivate the release, switching cam 141 is brought into or out of undisturbed movement path 152 of cam follower 142 . To vary the delivery location, a contact point 151 on switching cam 141, already described above, for the first contact between switching cam 141 and cam follower 142 to be moved in transport direction T is varied along transport direction T.

Activation and deactivation preferably takes place by pivoting switching cam 141 about a first pivot axis A144 fixed to the frame. Switching cam 141 is preferably varied by varying the distance between at least one of its ends relative to transport direction T and movement path 152 of cam follower 142.

In a particularly advantageous development, the switching device 141, 142 is controlled in such a way that the switching cam 141 is in its first operating position, i. H. in an active position, while the above The blower device is operated in the first operating mode and/or the above-mentioned braking device 48; 49 is operated in the first operating mode m1.

The first adjusting device 144 can be omitted. In this case, the pivot axis A44 or the point of action P143 with respect to the spatially fixed frame G is arranged fixed to the frame.

Together with one or more design features of the above sheet guiding device 47 and/or the braking device 48; 49 and/or to the blowing device 51; 52 and/or to the run-up section 78 and/or to the release device 139, or considered on its own, the delivery device 03 comprises at least one of a plurality of delivery stations I; 11, in particular for at least one stacking delivery station I to be regarded as a good sheet; 11, a non-stop stack changer 53; 54. The delivery system 03 preferably comprises several, in particular two or all delivery stations I; II a non-stop stack changer 53; 54

The - only or respective - non-stop pile changing device 53; 54 includes an auxiliary support device 166, preferably one that can be lowered by a motor; 167, e.g. B. an auxiliary stacking table 166; 167, the or between the top edge of the stack of the already formed stack 11; 12, e.g. B. ready for removal main stack 11; 12, and the sheet transport path running above it can be brought in. Preferably, the auxiliary stacking table 166; 167, in particular at least its supporting surface facing the sheet transport path, is mounted so that it can move vertically on the frame G or a frame part G of delivery system 03. In the active, i. H. operating state introduced in the fall path can be placed on the auxiliary stacking table 166; 167 by sheets B still arriving, an auxiliary stack 168; 169 are formed.

For this purpose, the drive means is in signal communication with a control means S171, for example, which is set up and/or programmed to actuate the drive means 171 in an operating situation in such a way that the upper edge of the stack is or is held at a definable height. For this purpose, the control means S171 is connected to a sensor system that detects the upper edge of the stack and/or to a control device that supplies information about the sheet flow.

The - for example horizontal - introduction and removal of the auxiliary stacking table 166; 167 into and out of the fall path, i. H. moving into a working position and back into a rest position is synchronized with respect to the point in time and/or in a correlation to a machine and/or printing material phase position Φ, d. H. clocked to the printing material flow. It is therefore preferably introduced in a specific phase position of the machine or of the next approaching sheet B.

B. the advantage that despite high sheet transport rate and possibly small distances successive sheets B when introducing the auxiliary stacking table 166; 167 as few specimens as possible, ideally not a single specimen, is damaged or has to be diverted.

This can be a change in the brightness of the background and/or a change in color for the two display modes. Here is a variant of particular advantage, in which a sufficiently large distance, z. B. at least ΔE _ab > 10, advantageously ΔE _ab > 20, is present. An example of this is in 47 a change in the image background is shown in an area 248 that here occupies almost the entire area, the different coloring of the background being symbolized by different filling. For example, a first background (e.g. grey) is active - e.g. B. 3 a) and 3 b) - If the control panel or display 243 or its display device 239 for setting a device of the first delivery station I; II is activated, and a second background active (e.g. green) - e.g. B. 3 c) and 3d) - When the control panel or display 243 or the display device 239 for setting a device of the second delivery station II; I is activated.

Here is a variant of particular advantage, in which a sufficiently large distance, z. B. at least ΔE _ab > 10, advantageously ΔE _ab > 20, is present. An example of this is in 47 a change in the image background is shown in an area 249 running around here in the form of a frame in the edge area of the display area, the different coloring of the background being symbolized by different filling. For example, a first background (e.g. blue) - in 3 a) and 3c) exemplary without filling - active if the first delivery station I; II is active, and a second background (e.g. red) - 3 b) and 3d) example with slash filling - active when the second delivery station II is active. The display device 239 is when changing the active delivery station II; I switched accordingly.

Are both means for visualizing the delivery station I currently active on the display 239; II as well as means for visualizing the currently active delivery station I; II provided, then for the implementation of the two means - except for identical means - any combination of the above. embodiments possible. However, a combination of respective areas 248; 249 changing backgrounds.

The control panel 243 comprising the display 239 represents an operator interface 253--particularly on the front side--or is comprised by such a user interface in addition to other operating means that may be present in the immediate vicinity.

In an embodiment that is particularly advantageous in terms of a particularly low risk of incorrect operation, the delivery device 03, designed as a multiple, in particular double-pile delivery 03, comprises for each of the delivery stations I; II own, e.g. B. single or multi-part control panel 243; 244, preferably as e.g. B. operating panel 244 designed as a structural unit, each with a display 239, via which format and/or transport-relevant devices 139; 48; 49; 51; 52, e.g. B. the gripper opening point and / or the placement speed vab and / or the blow strength, at the functionally associated delivery station I; II are adjustable (see e.g. 48 ). The control panels 243; 244 can in principle be provided on the long side, but are advantageously located in the area downstream of the second delivery station II, preferably on the end face of delivery system 03 opposite the sheet entry point.

The switching elements 228; 229 are here by appropriate activation on the respectively assigned control panel 243; 244 by appropriate activation in signal-technical connection with drives or actuators above. different format and/or transport-related devices 139; 48; 49; 51; 52 of the first or second delivery station I; II can be brought. Switching elements 245; 246; 247 is provided, through the actuation of which the device 139; 48; 49; 51; 52 can be selected.

In order to have a clearly recognizable assignment of the control panels 243; 244 to the delivery station I; II, the control panels 243; 244 in each case an identification 251; 252 have. In principle, this can be of any design, but here it is numerical, for example, by specifying the downstream position in the row of the intended delivery station I; II executed (see e.g. 49 ).

The two control panels 243; 244 form an operator interface 253--particularly on the front side--or are included in such an operator interface 253 in addition to other operating means that may be present in the immediate vicinity.

Basically z. B. in a display mode of the operation panels 243 different from the above setting mode; 244 in each case schematic representations or preferably even the actual geometric relationships for the essential functional units of the two delivery stations I; II be or will be displayed, d. H. with an information function without specific reference to a setting.

At the two control panels 243; 244 different devices 48; 49; 51; 52; 139 must be activated for their manipulation and the corresponding screen mask must be displayed. For example, in 49 for one of the delivery stations I; II, e.g. B. the second delivery station II, the braking device 49 is adjustable and the corresponding mask is displayed on the display 239, while for the other of the delivery stations II; I, e.g. B. the first delivery station I, the gripper opening point adjustable and the corresponding mask on the display 239 is shown. However - as in 50 exemplarily based on the blowing device 51; 52 is shown - on the two control panels 243; 244 same facilities 48; 49; 51; 52; 139 must be activated for their manipulation and the corresponding screen mask must be displayed.

Basically independent of the specific design above. Control and adjustment of the delivery device 03, but preferably in connection with the above Arrangement downstream of the second delivery station I; II or in particular at the front of the delivery device 03, with the delivery stations I; II each at least one z. e.g. device 48 mentioned above; 49; 51; 52; 103; 139 is assigned, which with regard to an adjustment or correction of the sheet guidance and / or deposit by actuators 63; 106; 147; 202; 124 comprehensive drives or actuating devices can be adjusted, at least one operating interface 232; 253 with at least one first actuating means 196'; 197'; 198'; 199'; 211'; 212'; 213'; 214'; 216; 217; 218; 219; 221; 222; 223; 224; 226; 227 228; 229; 231; 233; 234; 235; 236; 237; 238; 240; 241; 242 provided, by its actuation via a first signal connection 257; 261, an actuator 63; 106; 147; 202, e.g. B. drive means 63; 106; 147; 202 or pressure control valve 124 of a device 49 to be set; 52; 103; 139 of the second delivery station II; I and via a second signal connection 258; 262, an actuator 63; 106; 147; 202; 124, e.g. B. drive means 63; 106; 147; 202 or pressure control valve 124 of a functionally related device 49; 52; 103; 139 of the second delivery station II; I corresponding device 48; 51; 103; 139 of the first delivery station I; II is adjustable or adjustable, in particular provided with or adjustable with.

When setting the at least one first delivery station I; II and one of the first delivery station I; II downstream second delivery station II in the transport path; I-comprising delivery device 03 for delivering sheets of printing material B is used to adjust or correct the sheet guidance and/or deposit in the second delivery station II; I at least one device 48 that can be adjusted with a view to adapting or correcting the sheet guidance and/or deposit in the second delivery station II; 49; 51; 52; 103; 139 placed or discontinued, and as a result of and/or with the placement or discontinuation of this device 49; 139 of the second delivery station II also a setting or adjustment of a functionally relevant device 49; 52; 103; 139 of the second delivery station II corresponding device 48; 51; 103; 139 of the first delivery station I; II takes place.

When setting and/or adjusting a device 49 to be attributed to the second delivery station II; 52; 103; 139 there is a correlated setting and/or setting, i. H. "Mitstellen", the corresponding institution 48; 51; 103; 139 of the first delivery station 11. In principle, the transfer can be carried out at the same time or, if necessary, with a time delay.

This allows settings in the first delivery station I; II, which is less visible than the second or last of the delivery stations I; II, hit at the same time as the second.

The pairs affected by this facilities 48; 49; 51; 52; 103; 139 can be fundamentally different in design and/or geometrically arranged, with the specific design then being taken into account when setting the variable carried along. The devices 48; 49; 51; 52; 103; 139, at least as far as the mechanism of the setting variable X ₉₁ ; v _ab ; _X139 ; Y ₂₀₁ relates, carried out in the same way. As a result, no complex relationships need to be taken into account when adjusting, but—if desired—at most an absolute offset and/or an offset proportional to the level of the manipulated value.

In an advantageous development, when setting one or more of the adjustable devices 48; 49; 51; 52; 103; 139 of the rear or second delivery station I; II a setting or setting of the corresponding device 48; 49; 51; 52; 103; 139 of the first delivery station I; II using stored rules and/or radio tion, which here e.g. B. is generally referred to as deposited context 256. This relationship 254 is stored, for example, in circuit and/or data processing means 254 and can be implemented as a tabular or functional specification 256 .

The connection 256 or the rule 256 is set up and programmed in particular to set or adjust the device 48 associated with the first delivery station I and a measure for this. 103; 139 based on the stored relationship 256 from the device 49; 103; 139 of the second delivery station II and the drive of the first delivery station I; II concerned device 48; 49; 51; 52; 103; 139, ie directly to the drive means 63; 106; 147; 202 or the control means S63 assigned to it; S106; S147; S202 (see e.g. 51 ).

Such a modification of the value via a context deviating from a 1:1 application 256 - e.g. B. via an absolute offset and/or an offset that is proportional to the amount of the control value - preferably occurs when setting or setting format-relevant, i. H. devices 103 to be adapted to the respective format; 48; 49, e.g. B. when setting the side stop device 103 to the side and when setting the at least one braking device 91 in the transport direction T. It is particularly advantageous if the setting of the relevant device 103; 48; the first delivery station I; II takes place in such a way that the setting there is an excess in format compared to that setting at the first delivery station I; II effected for the actual format. Although this may affect the quality of the stack, it reduces the risk of a fault during filing.

In contrast, for predominantly transport-related, ie the movement of the sheet B related facilities 48; 49; 139; 51; 52, e.g. B. for setting the placement speed v _from the braking device 48; 49 and/or the setting of the blowing intensity on the blowing device 51, 52 and/or the release location on the release device 139 and/or the setting of the blowing devices 113q - at least with regard to the setting result to be achieved - are in a 1:1 relationship. The relationship 256 can directly map the 1:1 relationship or take into account any necessary correction due to different conditions in the design.

This procedure, which includes a modification, can be used with particular advantage when the second or rear delivery station II; I provided delivery stations I; II only serves to store waste sheets. In this case, for example, less stringent requirements are placed on the stack quality and the devices 48; 103 can be adjusted in a more generous way.

In a particularly advantageous embodiment, the auxiliary support device 166' and its mounting on the frame of the delivery device 03 are designed and arranged in such a way that the distance between the conveyor system 21 and the auxiliary support device 166' and thus a fall distance to the auxiliary support device 166' is as small as possible compared to conventional solutions, i.e. not only comes to rest under the braking device 48 . This is exemplary for all other examples in 62 schematically illustrated. In particular, the z. Auxiliary support device 166', embodied, e Viewed from the vertical direction, it comes to rest on at least one level intersecting the vertical extent of a braking device 91 . It comes with its top of the upstream end viewed in the vertical direction z. B. to be at most 100 mm, in particular at most 50 mm, compared to an active surface 112 facing the transport path of a braking device 91 in the operating position that is lower in height.

This vertical position can be assumed, for example, in a supporting position in which the auxiliary support device 166` is at least partially moved across the free cross section or in the active position mentioned, in which it is moved into the falling path, if necessary, of printing material sheet B to be deposited.

The device 53' described is particularly advantageous in connection with an embodiment of the delivery device 03 that has already been partially described above, whereby the upper side of the carrying device 36; 37 itself or a stack receptacle 311, in which at least parts of the carrying device 36; 37 can be lowered from above, a transport plane is fixed, to which at the same height laterally, d. H. transverse to the transport direction T of the delivery station II; I supplied sheet of printing material B, a transport plane of a one-part or multi-part transport section 273; 274 for unloading the stack 12; 11 adjoins and/or which is provided at a height which is opposite to that set by the vertically movable support device 36; 37 is raised by more than a third of the vertical adjustment range and/or is above a third of a stacking space height formed between a floor surface supporting the delivery device 03 and the conveyor system 21.

It is advantageous downstream of the transport section 273; 274 is provided in the transport path for an inline loadable vibrating device and/or cutting device.

If a stack receptacle 311 is provided, this can preferably be removed operationally from the stacking space and reinserted into it, preferably depending on the planned production, in the delivery device 03.

In an advantageous development, the carrying device 36; 37 itself or a stack receptacle 311 that may be provided, into which at least parts of the carrying device 36; 37 can be lowered from above, on the upper side facing the bottom stack sheet, transport and/or friction-reducing means 312; 313 and/or is in the manner of such a transport and/or friction-reducing means 312; 313 comprehensive transport table 311 is formed.

During operation of the delivery of printing material B in the delivery device 03 of a sheet-fed printing press 01 with the conveyor system 21, through which printing material B received on the input side to a more upstream, first delivery station I; II are funded and there optionally to form a first stack 11; 12 one above the other directly or indirectly on a vertically movable support device 36; 37 deposited or to a downstream, second discharge station II; I are promoted, where they form a second stack 12; 11 are deposited, is used to carry out an uninterrupted stack change at the first delivery station I; II an auxiliary support means 166` from a downstream of the stacking space of the first delivery station I; II resting position for taking an active position in the fall path for in the first delivery station I; II spent printing material sheet B to be deposited.

In an operating situation in which one or more or a defined number of printing material sheets B or all printing material sheets B of the production via the first delivery station I; II are to be transferred, the auxiliary support device 166` for supporting the printing material sheets B to be transferred is moved at least partially over the free cross-section of the stacking space below. This occurs in the event that a sheet B considered as a good sheet is in the first delivery station I; II and considered as a waste sheet B in the second delivery station II; I should be filed z. B. for the sheets B that are considered as waste sheets during the set-up of the machines.

Ideally, the auxiliary support device 166` is moved to a position as close as possible to the transport path in order to assume the support position. For example, to assume the support position, it is brought into a position in which an upper side of the upstream end of the auxiliary support device 166', which is brought at least partially over the free cross section, comes to rest at at least a height intersecting the vertical extent of a braking device 91, viewed in the vertical direction.

Preferably, in the first and/or second delivery station I; II palletless depositing on the carrying device 36; 37 and/or palletless transport of the stack 11; 12 from the support 36; 37 to the laterally adjoining transport section 273; 274 via transport and/or friction-reducing means 312; 313, preferably in a manner set forth above.

In an embodiment which is advantageous with regard to the risk of damage caused by the transfer, at least the downstream first delivery station I; II with the device 53' acting from downstream and/or the transport and/or friction-reducing means 312; 313 and/or the stack receptacle 311 and serves e.g. B. the stacking of good sheets B during the delivery station II provided further downstream; I serves to stack sheets B considered as waste sheets. In this case, it can be advantageous if, during the retraction of the auxiliary support device 166`, a "gap" is formed in the stacking of sheets B to be stacked as good sheets, i. H. a number of sheets B on the stack 12 formed downstream in this variant as a waste stack; 11 continue to be funded. The auxiliary support device 166` can also be in the highest possible position, e.g. B. be spent in the above support position for sheet guidance and serve when transferring the first stack 11, designed here as a stack of good sheets, to support the sheets B.

In an embodiment that is advantageous in terms of operability, in which the sheets B considered to be good sheets are easier to see and the delivery device 03 is therefore easier to adjust, e.g. B. the second delivery station II; I the stacking of sheets B considered as good sheets while the delivery station I provided further upstream; II serves to stack sheets B considered as waste sheets.

In any case, the second delivery station II; I advantageously include a device 54 for the uninterrupted stack change, in the manner of the first type with auxiliary support means 166 that can be retracted from upstream, or in the manner of the two th type 53' can be provided with an auxiliary support device 166' that can be retracted from downstream.

In multiple delivery device 03, there is the partial problem that sheets B that have a front pile delivery I; II are transported away, fall down and receive an upward impulse when running onto a subsequent guide element and/or front stops. The result is restless further sheet travel and a disruption of the following sheet deposit. Damage to sheet B may also occur.

Regardless of one or more of the aforementioned design features for at least one first and one downstream second stack delivery I; II having delivery device 03, but also particularly advantageous with one or more of the aforementioned design features, it is for gentle transport over a first stack delivery I; II is particularly advantageous if the sheet B to be transferred is not even in the gap between the sheet guiding elements 47.1; 47.2; 47.3; 47.4; 47.5; 47.6; 47.7; 47.8; 78 collapses and therefore not against the following sheet guiding element 47.5; 47.6; 47.7; 47.8; 78 starts (see e.g. 66 until 70 ). As already explained above, here too - where not explicitly emphasized - under "first" and "second" pile delivery I; II with more than two possible stacks I; II not the actual first and second pile delivery downstream I; 11, but a first-mentioned and a further downstream second-mentioned pile delivery II; I understand.

Such a delivery device 03, in particular of a sheet-fed printing press 01, comprises at least one first pile delivery I; II and a downstream second pile delivery II; I, wherein input-side printing material sheets B received by the holding devices 32 of a conveyor system 21 via the first conveyor section 41 to the first stack delivery I; II are conveyable, where they can be delivered either to form a first stack 11 from the conveyor system 21 or through the conveyor system 21 via a second conveyor section 42 to the second stack delivery II; I further promoted and can be delivered there to form a second stack 12. Above the stacking space of the first stack delivery I; II is a holding device 317 is provided with a holding means 318, through which a through the conveyor system 21 to the second pile delivery II; I the printing material sheet B to be conveyed further is or can be temporarily held from above against its free end falling below the entry level of the second conveying section 42 .

The holding device 317 is arranged above the movement path of the holding device 32 conveying the printing material sheet B.

Between the first and second pile delivery I; II at least one sheet guiding element 47.5; 47.6; 47.7; 47.8; 78 is provided, on which the free end of the printing material sheet B conveyed further by the holding device 32 of the conveyor system 21 rests after it has been released by the holding device 317. This enables a flutter-free guided further transport.

In a preferred embodiment, the holding means 318 is designed as a circulating means 318, in particular a circulating belt 318, which includes appropriate means for developing a holding effect on the sheet B. For this purpose, belt 318 preferably comprises air passage openings in the direction of at least one suction air channel 319 surrounded by belt 318 and having an opening in the direction of the transport path. When a negative pressure is applied, air flows from the side facing the sheet path into the openings and generates negative pressure in the surface area a suction effect. Alternatively, the band 318 can be in operative contact with a generator, through which it can be subjected to electrical charges. Holding then takes place via electrostatic forces.

Although holding means 318 could in principle be arranged in a stationary manner above the stacking space and the conveyed sheet B could be or be pulled along it, holding means 318 is preferably at least in the region of its surface interacting with the printing substrate sheet B to hold it, for at least the duration of the interaction also movable with the sheet of printing material B to be further promoted.

In a simple embodiment, the moving along could be effected by the sheet B being conveyed and held. However, the holding means 318 is advantageously positively driven and/or is positively driven by its own drive means or preferably via a drive connection for driving the holding device 32 of the conveyor system 21 .

In an advantageous embodiment, the drive as circulating means 318, z. B. band 318, trained holding means 318 synchronously with the drive of the z. B. as a gripper carriage 32 holding devices 32 of the conveyor system 21. The drive is such that essentially, ie with ± 5% maximum deviation, the same speed of holding means 318 and holding device 32, in particular gripper carriage 32, is present. The circulation means 318 can have two or more Deflection and/or guide elements 321, e.g. B. hubs 321 or rollers 321, which are rotatable about a direction transverse to the transport direction T axis. One or more of the hubs 321 or axles is driven, for example, directly or indirectly by a traction means 31, e.g. B. chain 31. This ensures a completely synchronous feed and eliminates the risk of the sheet B being upset or dragged along by the relative speed from the outset. The chain 31 engages, for example, in a sprocket 326, which directly carries the hub 321 or the roller 321 or is non-rotatably connected to the deflection means 318, for example via an axle stub.

In one embodiment, the circulating means 318 is provided on at least one end face with a circulating drive means 322, e.g. B, a belt or in particular a chain connected, which several, z. B. two deflection and / or guide elements 321 rotates. In this case, the drive from the traction means 31 can, for example, be divided into several, e.g. B. both deflection means 318 take place in the manner mentioned above.

In order to be able to bring the sheet B as close as possible to the holding means 318, in the event that the holding device 32 conveying the sheet B has a significant cross-sectional thickness and/or z. g. as a gripper carriage 32, the deflection and/or guide element 321 comprises a clearance 323 and/or the drive means 322 at a distance from adjacent holding devices 32 include bridge elements 324 and/or the holding means 318 itself can be designed to be flexible or also at a distance from adjacent holding devices 32 have inwardly receding channel-like depression.

In a particularly advantageous development, a blowing device 51 is also provided above the stacking space of the first stack delivery I, through which printing material sheets B to be deposited in the first stack delivery I can be subjected to blowing air from above. The above the stack 11; 12 arranged blowing device 51 supports the stacking of the stack to be formed 11; 12. This blowing device 51 can advantageously be designed in a manner already explained above. In particular, the blowing device 51 comprises a plurality of groups 113q, e.g. B. blower tubes 113q, or upper groups of such groups 113q or blower tubes 113q of blower air openings 114r directed in the direction of the transport path, which can be activated and deactivated via one or more switchable valves 116 and/or which can be activated by a correspondingly equipped compressed air source 119 via a line connection on its Inside can be acted upon with air at a pressure of more than 0.6 bar above normal pressure.

In a particularly compact and effective embodiment, instead of just one suction channel 319 designed as a suction box 319, several transverse suction channels 319 are provided one behind the other in the transport direction T, with one or more of the above-mentioned blower tubes 113q being arranged between several pairs of adjacent suction channel pairs. Due to the minimal possible distance to the arc path, both a particularly effective blowing and suction can be realized.

When operating a delivery device 03, in particular of this type, with at least one first stack delivery I; II and a downstream second pile delivery II; I, wherein input-side printing material sheets B received by holding devices 32 of a conveyor system 21 via a conveyor section 41 to the first pile delivery I; II are funded, where they are either delivered to form a first stack 11 from the conveyor system 21 or through the conveyor system 21 via a second conveyor section 42 to the second stack delivery II; I further promoted and can be delivered there to form a second stack 12, we a through the conveyor system 21 to the second stack delivery II; I further to be conveyed sheet of printing material B above the stack space of the first stack delivery I; II by a holding device 317 from above against falling off his free, d. H. not held by the holding device 32, in particular the trailing end below the entry level of the second conveyor section 42.

The holding device 317 sucks the sheet of printing material B to be conveyed upwards, preferably via suction air, or alternatively attracts it through static charging (see e.g. 69 ).

A holding means 318 comprised by holding device 317 preferably moves along with the printing substrate sheet B to be conveyed further, at least for the duration and in the region of its interaction.

In particular, the holding means 318 is electronically synchronized to move the holding device 32 or positively driven together with the holding device 32 via a drive connection.

The holding device 317 is preferably activated in its holding effect for a sheet of printing material B to be transferred and for one on the first pile delivery II; I to be deposited sheet of printing material B deactivated.

In a particularly advantageous development, a sheet B to be deposited in the first pile delivery I is lifted from above using a device integrated in the holding device 317 and/or also above the stacking space of the first pile delivery I; II provided blowing device 51; 52 blowing air applied (see e.g. 70 ).

Preferably, blast air is applied from a plurality of groups 113q, one behind the other in transport direction T, running transversely to transport direction T, of blast air openings 114r directed in the direction of the transport path, e.g. B. blowpipes 113q, and/or with compressed air at a pressure of more than 0.6 bar above normal pressure.
