Their drive 106 is operated or operated such that the interacting with the sheet B active surface 112 of the holding means 92 in at least part of the contact time between holding means 92 and sheet B with respect to the currently present, determined by the conveyor system 21 conveying speed v32, z , B. a speed of the holding devices 32 and gripper carriage speed v32, lower, z. B. operated by at least 50% lower storage speed v _ab and / or operable. In a preferred embodiment, its drive 106 can be operated dynamically in such a way that the effective area 112 of the holding means 92 cooperating with the arc B at least between the currently present, determined by the conveyor system 21 conveying speed v32, z. B. a speed of the holding means 32 and gripper carriage speed v32, and a lower, z. B. is at least 50% lower storage speed v _from continuously variable.

An abzulegender printing material sheet B _n is the input side of the braking device 48; 49 by a holding means 92 of the braking device 48; 49 received, in particular pneumatically sucked, which is at or approximately with, ie more than 95%, the conveying speed v32, ie without or almost no relative movement between the holding means 32 of the conveyor system 21 and the holding means 92 of the braking device 48, 49, in the transport direction T moves. After an opening of the holding device 32 has taken place, ie for example after gripper opening, the speed v92 of the holding means 92 is reduced by speed change to the lower depositing speed v _ab , thereby braking the sheet B and finally deposited on the stack 11.

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

The curve or its course can depend on the current production speed, that is to say on the input-side conveyor speed v32 and / or on the nature of the printing material B, and can vary automatically depending on this.

To correct a faulty drop and / or to adapt to a new format length L _B , as z. B. may be required in a production change, the curve and / or its course by operators via variation of corresponding, the curve defining parameters can be changed. Here, at least the height of the above Storage speed v _from , ie the present after lowering lower end speed, changeable 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 or 92, by the operator changeable.

An undeliverable, ie to be transferred sheet B _{n + 1} is also the input side of the braking device 48; 49 by a holding means 92 of the braking device 48; 49 recorded, in particular sucked pneumatically, which is approximately, ie a maximum deviation of z. B. at most ± 10%, or preferably at most ± 5%, in particular at most ± 3%, with conveying speed v32, ie virtually without relative movement between the holding means 32 of the conveyor system 21 and the holding means 92 of the braking device 48, 49, moved in the transport direction T. However, this state is maintained during the further transport of the relevant sheet B _{n + 1} until the sheet B _n with its trailing end 111, the braking device 48; 49 left or just leaves. The bow B, which is also held by the holding device 32 of the conveyor system 21, is moved downstream via the brake device 48; 49 directly downstream dispensing stations I; II away to another dispensing station I; II or a sheet removal device 87 promoted. To avoid wave formation is the above-mentioned possibly existing deviation z. At most - 10%, preferably at most - 5%, in particular at most - 3%.

The dispensing station I; II, in particular at least the first dispensing station I, is thus a braking device 48 in the printing material path; 49 upstream or upstream, which is operationally operable in two different operating modes and / or operated is or will. This is done in dependence on the intended for the incoming bow B _i transport destination.

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 stack 11, are to be stored, the rotational speed of the drive 106 per abzulegendem bow changes at least once from a first speed v _an effecting speed, the z. B. as the speed of the incoming sheet substantially - ie with a maximum deviation of ± 10% - corresponds to the above-mentioned conveying speed v32, to a storage speed v _from causing speed and back to substantially conveyor speed v32. If several successive sheets B _n sequentially store, so that this first operational mode m1 repeated as often as necessary so that the brake means 48, 49, that is to be deposited, the holding means 92, the speed v92 between conveying speed v32 v on depositing speed _from and back in time to the incoming and Sheet B _n changes.

When changing to storage speed v _from the speed v92 of the holding means 92 is preferably lowered during the active contact with the conveyed sheet B to a speed v _from the z. B. at most 50%, advantageously less than 20%, preferably less than 10% of the conveying speed v32. The substantially higher conveying speed v32 corresponding to the higher speed v92 of the holding means 92 is in a stationary operating situation over 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 storage 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 corresponding 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 front edge 109 of the sheet B to be deposited is _{n + 1} ; B _P only less than half an arc length from the escape s2 to the downstream stack trailing edge and the leading edge 111 of the sheet B _{n + 1} to be deposited; B _P only less than half Arc length from the escape s1 to the upstream stack leading edge is removed.

In the second operating mode m2, z. B. a guide mode m2, in which one or more sheets B on the first stack 11, z. B. Makulaturstapel 11, and the dispensing stations are to be led away I, the drive 106 over at least the entire phase of the contact between the braking device 48, 49, d. H. the holding means 92, and operated over the stack 11 and the dispensing station I wegzuführendem sheet B at a speed which causes at the holding means 92 a substantially the conveying speed v32 corresponding speed v92. If there is a constant conveying speed v32, this is likewise at least during o. G. Contact phase constant. This second operating mode m2 is basically independent of the presence or the specific embodiment of a first operating mode, but is of particular advantage in connection with an embodiment of a first operating mode set forth here.

In a preferred embodiment of the braking device 48; 49 are clocked via corresponding switching means 107 activatable and deactivatable holding means 92 is provided. For clocking, the switching means 107 is in signal communication with control means S107, for example, which is designed and configured to synchronize activation and deactivation of the holding means 92 and / or to effect a correlation to a machine and / or printing material phase position Φ. In the case of two operating modes m1; m2, these differ, for example, not only in the phase-related velocity profile, but also in the switching profile for the wiring, d. 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 at least part of the positive acceleration phase from the depositing speed v _down to the conveying speed v32. In the embodiment as suction elements 92 in this phase at least temporarily set the suction, ie the application of a Vacuum p ^- interrupted on the suction element 92.

In the second operating mode m2, the activation of the holding means 92 is maintained over at least the entire phase of the contact between the braking device 48, 49, ie the holding means 92, and the sheet B to be passed over the stack 11 and the dispensing station I, respectively. Preferably, the suction or the negative pressure p- remains maintained over the entire cycle. In the embodiment as suction elements 92, the suction remains switched on in at least this contact phase, that is, the negative pressure p ^{- maintained} at the suction element 92. Preferably remains the suction or the negative pressure p ^- over the entire cycle from occurrence of the arc leading to B _n in the range of the braking device 48; 49, in particular in the effective range of the holding means 92, until the next sheet B _{n + 1} enters the region of the braking device 48; 49, in particular in the effective range of the holding means 92, turned on. If several consecutive sheets B _{n + 1} ; B _{n + 2 can be} successively transferred, the suction or the negative pressure p ^- remain switched on over the duration of the relevant cycles.

Sucking over the entire cycle, in particular over the cycles of several sheets to be transferred, ensures that the sheet in the second operating mode m2, ie the guide mode m2, acquires the sheet B _{n + 1} to be transferred and essentially without relative movement over the sheet spans to be transferred stack 11, 12. As a result, a "breaking in" of the sheet to be transferred B _{n + 1 is} prevented in the storage shaft of the stack 11 to be transferred or at least reduced, which allows a transfer without sacrificing quality. This is particularly relevant for high-speed productions.

A suction air permanently switched on in the second operating mode m2 favors 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 mutually different provisions for the generation of set values for the speed v92 of the holding means 92 held. The regulations include, for example, a dependency on the conveying speed v32 and can also be dependent on further influencing variables and can be parameterized by operating personnel.

In this case, the regulations in each case include different assignment rules between the current conveyor speed v32 and a setpoint or setpoint course for the speed v92 of the holding means 92. For the assignment rule of the second operating mode m2, at least the duration of the contact with the sheet B is at 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 contact with the sheet B at least one ramp with a relative to the conveying speed v32 sloping course of the holding means speed v92 provided.

For example, the blown air line 98 is designed as a blow pipe with a circular outer peripheral cross-section and the material portion 84 in the form of a circular arc in cross-section at least in the region of its section opposite the blown air line 97. The blast air openings 97 provided in the material section 84 have, at least in a printing material sheet guided in the direction of movement over the starting section 84 extending direction on the opposite to the outlet openings larger opening cross section. This ensures, for example, a secure passage of air.

In a particularly advantageous development, the preferably tube-like blown air line 98 can be mounted pivotably about an axis extending in the transverse direction. This makes it possible to adjust the position of the blown air outlet along the sheet movement direction at least slightly, in particular with respect to the outlet openings in the above-described larger blown air openings 97.

The starting section 78 designed in this way can in principle be used independently of the design of the dispensing device 03 with a plurality of dispensing station I; II be provided in the region of a beginning of a sheet guiding elements comprehensive conveyor line. However, this is preferably at the beginning of a between two dispensing stations I; II arranged conveyor line provided.

Conventionally, the sheet B, guided only at the front edge by the conveyor system 21 or the holding device 32, in particular the holding elements 56, sinks into the shaft of the overrun dispensing station I; II until it is in equilibrium with the forming at the bottom of natural air cushion. The continuation of the bowing on predominantly horizontal guideway can at the end of the overrun dispensing station I; II - especially in certain operating situations with, for example, low stack level .- lead to a harmful level jump. In this case, the natural air cushion can not, the sheet B as a wing over this stage on the following sheet guide 47.5; 78, in particular run-up plate 78 to lift. Especially at higher speeds, it may come to a striking contact with damaging contact on the underside of the arc B.

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

At least the upstream end of the starting portion 78 is in height to the variable stacking level, d. H. the height of the uppermost sheet B in the stack 11; 12, adjustable. Preferably, this end - in particular via control means - automatically adjustable in height to the variable stack level. For this purpose, the drive means 283 comprised by the actuator, in particular its control unit or drive controller, is in signal connection to a control means which sets 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 placement or the variation takes place at least within an operationally provided adjustment range, which extends from an upper layer L _O , in the continuous printing in already partially formed stack 11; 12 a minimum height without further height variation of the starting section 78 is stored until reaching the target stack height, down to a lower layer L _U , in which z. B. is stored in production at the beginning of stacking (see, eg. Fig. 9a ) and c). The latter is approached, for example, when the time of the process of the stacking table 36; 37 should be used at least in part until reaching the working height assumed above for the printing and / or if at the beginning of stacking the working height, ie that in the above-mentioned Continuing pressure level of the top sheet layer to be ideally taken, due to a limited travel for the stacking table 36; 37 is not accessible with low stack heights. The between these two layers L _O ; L _U located layers L _Z (see eg. Fig. 9b ) may in principle be stationary in other special operating situations or become, however, are or are regularly on the way between the two other layers L _O ; L _U only drive through dynamically. The operationally provided adjustment range between the upper and lower layers L _O ; For example, L _U amounts to at least 50 mm, preferably more than 100 mm. In principle, one or both sides can be anfahrbei beyond these two limits (position L _O and layer L _U ) layers, which, however, are approachable, for example, for set-up or maintenance or other non-operational actions.

The start-up section 78 is designed and / or supported by the said variability in such a way that it also reduces levels which are lower than the maximum or in-progress stack level, the current stack level with the, preferably horizontal, sheet guide level higher for this case, ie. H. the level specified by the course of the conveyor system connects. Here, the "stack level" is understood to mean the vertical position of the upper stack end.

As drive means 283, for example, a motor 283, in particular an electric motor 283 is provided which z. B. via a gear 284 medium or directly on the sheet guide 47.5; 78 and start-up section 78 attacks. As a gear 284 may advantageously be provided a spindle drive 284, whose driven by the motor 283 threaded spindle 286 in a middle or directly with the sheet guide 47.5; 78 or the start-up section 78 connected bearing block 287 engages. In principle, the drive for varying the position of only one side can be done by only one actuator with motor 283 or from two sides by a respective actuator with motor 283. In an advantageous embodiment, the positioning is effected by an actuator with only one motor 283, but of two Pages. For this purpose, for example, both sides medium or directly on the starting section 78 engaging gear 284 are provided, the movement of which is mechanically, for. B. via a shaft 291, is synchronized. The two synchronized drive trains of the actuator are driven by a motor 283 at any point, for example on one of the two sides.

The sheet guide 47.5; 78 or the sheet guide 47.5; 78 in the vertical position varying drive means 283 may be manually adjustable, for example via controls not shown here. Instead or advantageously in addition to this, the sheet guiding element 47.5; 78 or the sheet guide 47.5; 78 varying in the vertical position drive means 283 preferably automatically via control means adjustable, preferably - at least in an operationally provided adjustment range or a partial area - correlated to the vertical position of the stack top in the upstream stacking space 44; 46 adjustable. In operation, the vertical position of at least the upstream end of the starting section 78 is thus correlated to the vertical position of the stack top in the upstream stacking space 44; 46 varies. Here, the vertical position of the upstream end or the drive means 283 is controllable, for example, depending on the position of the stack top information representing. Instead, or in addition thereto, the vertical location of the upstream end or drive means 283 may be correlated with and / or correlated to control the vertical position of the stacking table 36; 37 be controllable and / or controlled.

In order to provide information representing the position of the top of the stack, it is possible, for example, to provide a sensor system configured for this purpose. Their output signals or processed results are z. B. the control means or are zuleitet. For example, above the stack 11, 12, a distance sensor or in the upstream end face of the starting section 78, a sensor which detects the upper stack edge can be provided. The sheet guiding element 78 is preferably arranged and / or supported in the delivery device 03, so that, in the case of the vertical position of the upstream end of the sheet guiding element 78 lying within the operationally provided adjustment range, the respectively stacking space 44; 46 perpendicular to the transport direction T facing end face of the sheet guiding element 78 come to rest on a substantially vertical line. In this case, the "substantially vertical line" should also include an actually rectilinear vertical line such as a straight line with a maximum deviation of 5 ° to the vertical straight or constant or varying curved whose minimum radius of curvature twice the length of the extending in the transport direction T. Sheet guide 78 corresponds. It is common to this course of the lines that the stack-space-adjacent end-face areas directed in the respective vertical position in each case opposite to the transport direction T and thus also the position of the first contact by a leading-up sheet B do not change significantly despite vertical variation in the horizontal direction.

This substantially vertical location of the upstream end is via an actuator which acts directly on or at least near the end to be moved at the start-up section 78 and the start-up section 78 displaced at the point along a vertically extending rectilinear motion.

In an advantageous embodiment, the sheet guiding element 78 or z. B. also known as run-up plate 78 start-up section 78 executed in such an advantageous embodiment and / or stored so that with varying vertical position of the upstream end, the vertical level of the bow B at the downstream end supporting guide surface 79 remains. However, this should be against the background of the Leitelementdimensionen negligible deviations in the range of a few millimeters, z. B. of up to 5 mm, mitumzufassen. By maintaining the level can be a Transition to a subsequent section or sheet guiding element 47.5 are held quasi stepless in the above sense regardless of the vertical position of the upstream end.

In the event that o. G. Variation of the height of the upstream end is provided along og, substantially vertical line and a maintenance of the level at the downstream end, a guide device with a frame-fixed stop means 288 is provided, which is fixed to a run-up portion, in particular in a downstream end closer than to the upstream end closer to the area of the starting section 78 provided stop means 289 for the defined position assumption of the downstream end of the start-up section 78 cooperates.

The stop means 288; 289 are designed such that when vertical variation of the upstream end along the substantially vertical line and the associated horizontal movement of the downstream end in the transition region to the downstream following sheet guiding element 47.5 effective guide surface 79 in the above manner maintains the level. In this case, z. B. at least one of the stop means 288; 289 a correspondingly shaped stop curve on which during the relative movement of the corresponding stop means 289; 288 supported. For example, the frame-fixed stop means 288 comprises such a curve, on which the z. B. trained as a roller 289 run-start fixed stop means 289 along. The abutment portion fixed stop means 289 may be supported from below by the frame-fixed stop means 288, wherein - if necessary, among other things - the gravity ensures a secure contact. Conversely, the abutment portion fixed stop means 289 can be pressed from below against the corresponding, frame-fixed stop means 288. In this case, this can either be effected statically via a spring element acting on the starting section 78 or else via a drive means, by which means z. B. the corresponding stop means 288; 289 either in contact with each other and except Contact are available. In the embodiment with an embodiment of a start-up section 78 which can be swiveled down with the downstream end in the event of a fault, the contact piece engaging on the starting section 78 and for the contact between the corresponding stop devices 288; 289 worrying drive means by the swiveling effecting drive means 104 may be formed.

Preferably, the start-up section 78, which can be varied in its vertical position, is located at the beginning or at the upstream end of an intermediate discharge station I; II arranged conveyor line provided. A preferably horizontally extending section of the same sheet guiding element or a preferably horizontally extending further sheet guiding element 47.5 can adjoin the downstream end of the starting section 78. In a further variant, the sheet guiding device on the between two discharge stations I; II lying conveyor line end with the upstream end of the start-up section 78.

The start-up section 78, which is also referred to as start-up plate 78, can be made in several parts, eg. B. may be formed of several adjoining baffles. In this case, the guide contour of the start-up section 78 can sit flat and curved sections together. In an advantageous embodiment, the starting section 78 comprises in the region of the guide surface 79 and / or in the region of the bent edge 84 o. G. Air passage openings, in particular blowing air openings 69; 97 has. For this purpose, the starting section 78 in the manner described above z. B. supplied with blowing air.

In addition to the above-mentioned blowing device and / or the vertically variable embodiment of the upstream start-up section end or on its own, in a further advantageous embodiment or variant of a start-up section 78, an abutment device can be designed such that a plurality of abutment means 83; 86 individually or at least in several groups by a corresponding number of - in particular own, ie basically to be actuated independently of each other - drive means 64 and drive means 99 between the active and the inactive position movable, z. B. pivotable or z. B. are translationally movable.

For moving all, one group or preferably of the single stop means 83; 86, the drive means 99 can basically be designed arbitrarily. However, it is preferably embodied as a cylinder-piston system 99 that can be acted upon with pressurized fluid, in particular as a pneumatic cylinder 99.

The groups or individual stop means 83; Although 86 moving pneumatic cylinder 99 may in principle be connected 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, briefly valves 101, provided at which, for example, compressed air is present on the input side and which via appropriate control signals the applied compressed air to the output side can be switched and via a line connection to the respective pneumatic cylinder 99 acted upon.

In principle, the groups or preferably individual stop means 83; 86 via the drive means 99 associated switching means 101 and valves 101, for example, in the manner of a valve terminal, be centrally summarized at one point. In a preferred embodiment, the switching means 101, in particular valves 101 but decentralized and / or at least in groups or preferably all spatially spaced from each other, in particular arranged in each case close to the associated pneumatic cylinder 99. In this case, the switching means 101 or valves 101, for example, each closer to the associated pneumatic cylinder 99 arranged as to or one of the other pneumatic cylinder 99. At least they are closer to the associated pneumatic cylinder 99 arranged as half of the distance between the two furthest apart pneumatic cylinders 99th

A switching of the valves 101 takes place, for example, synchronized and / or in correlation to a machine and / or printing material phase position of control means S83 (S86) of a control device, which for example is in signal communication with a sensor or a master, from which it controls the machine and / or printing material phase position and / or representing information I (Φ) receives. A movement of the stops in the active position can then take place, for example, exactly in a gap between two incoming printing material sheet B. In known and / or constant sheet travel, for example, a dead time compensation can be done by a pre-control.

The control means S83 (S86) may be part of a higher-level machine control or else provided in a decentralized manner and, if necessary, connected to such.

The switching of the stop means 83; 86 takes place z. B. depending on whether a printing material B in the upstream dispensing station I; II, or should be forwarded to another dispensing station II or a sample sheet removal.

In the case of the abovementioned blowing device integrated in the region of the edge 84, for example, an activation and deactivation of a blast air supply takes place as a function of whether a printing material sheet B in the upstream dispensing station I; II, or should be forwarded to another dispensing station II or a sample sheet removal.

In an advantageous development of the starting section 78, blowing air openings 69, in particular in the manner of venturi nozzles 69, are provided in the guide surface 79 and / or in the surface of the sheet guiding element 41.5 continuing the guide surface 79.

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

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

Furthermore, in a variant of embodiment not shown here, the stop device comprising the pivotable stop means 83 can be integrated in the structural unit of the start-up section 78, which already hold down the printing material sheet B applied in the upstream dispensing station I, while subsequent printing material sheets B lead to a further dispensing station II or one Removal point to be transferred. Such a holding device is z. B. in the event of an intentional re-storage of another sheet B on the stack 11, 12 of the upstream discharge station I at least for the time required for this from the movement path of the sheet B removable. By such a holding device entrainment already filed bow B can be prevented, but at least made difficult.

When filing change from the first to a subsequent stack 11; 12, z. B. the waste stack 11 on the sheet stack 12, the necessary for filing on the first stack 11, the sheet B catching stop means 83 are brought from trajectory of the sheet B, for the transfer of printing material B, z. B. Gutbogen to have a free passport room available. However, this may be the problem occur that - z. B. despite any possibly provided blowing device - the last just dropped bow B, if necessary, a still provided with trapped air "floatable" Ries and by the fluidic forces of the z. B. designed as a gripper carriage 32 holding devices 32 which promote the bow B at full speed, a drift is created, which can lead to entrainment of the ream or single bow B at the end.

In order to be able to counteract this, one or more stops 83 - as in the first embodiment set forth above - be embodied and movably mounted so that they are in the active state, ie. H. in an active position, in the trajectory of the printing material B are located and this with a leading end of the sheet facing side, z. B. a stop surface, are effective as a front stop, and in the inactive state, d. H. in inactive position, from the trajectory incoming printing material B moved out, that are arranged outside the trajectory, and are for the incoming printing material B without impact effect. In addition to this, one or more of the movable stop means 83 is associated with a holding means 299 forcibly moved with the movement of the stop means 83 and protruding beyond the stop face in the direction of the incoming printing material sheet 83 in at least one inactive position of the stop means 83 Retains the uppermost substrate sheet B in the region of its downstream edge from being lifted off and entrained by the printing material sheet B to be transferred. Preferably, the holding means 299 comes in the active position of the associated stop means 83 downstream and / or above the movement path of the printed material sheet B to be delivered to the stack 11 and inactive position of the associated stop means 83 below the trajectory of over the stack 11 away to be further promoted Abruckstoffbogens B and lie above the uppermost printing material B of the stack 11.

The stop means 83 associated holding means 299 thus stops at inactive Stop means 83, the uppermost layer of the stack 11 down against picking and / or entrainment by subsequently to be transferred to printing material B. In this case, the holding means 299 in holding position actually or almost, z. B. with a maximum of a slight distance, spent in contact with the topmost stack layer. A maximum slight distance can z. B. correspond to a length, with which viewed in plan view, the retaining means located in the holding position 299 and the stack floor plan at the downstream end of the stack 11 in the transport direction T overlap.

The assignment of the holding means 299 can be implemented in a preferred embodiment such that an upper part of the stop means 83, which is in an inactive position, comprises the holding means 299 which reaches upstream over the stack edge. Alternatively, a holding means 299- rigid or via a mechanical coupling - be so connected to the stop means 83, so forced by movement of the stop means 83, the required movement of the holding means 299 takes place and / or conversely with movement of the holding means 299 the relevant movement of the stop means 83rd

Preferably, the stop means 83 as in the active position of the approaching printing material B serving as a front stop stop 83 is formed, in particular in the region of its inactive position upper end - for holding down the topmost stack layer as holding means 299 an upstream of the stop surface 302 rising and with the stack floor plan at its downstream end at least as a holding means 299 overlapping projection 299 in the manner of a downwardly bent retaining finger comprises. The hold-down projection 299 or holding finger can also be referred to as a cover mark 299.

In the execution of the stop means 83, in which they include the holding means 299 beat when stored on the stack 11 to be deposited to printing material B, z. B. waste sheet, against these movable stop means 83 and stops 83 at. at further conveying the printing material B, z. B. good bow, over the stack 11 away, z. B. to a subsequent discharge station II, these stop means 83 are moved from their lying in the trajectory "catcher position" in an out of trajectory retreat position, wherein the embraced by the stops 83 holding means 299 and 299 Deckmarken the topmost stack arch against entrainment and / or hold against slipping.

In principle, the movement of the stop means 83 can be effected by pivoting, wherein z. B. contrary to the above embodiment, the pivoting for taking the retreat position not downstream, but takes place in the upstream direction. In this case, by the upwardly pivoted stop means 83, for example, hold down the topmost stack sheet. The movement can also take place on any other movement path, provided that the stop means 83 and the retaining means 299 assigned to it assume the positions defined above.

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

Preferably, the stop means 83 is arranged and / or stored such that the holding means 299 in the retraction movement in the entire operating range, the z. B. from an upper layer, in which an incoming sheet B is trapped or is to be, to a lower layer in which an incoming sheet B can happen and the upper stack sheet is held down, the stack floor plan in the region of the downstream end stack never leaves completely, ie always one in plan view og overlap between holding means 299 and stack floor plan remains. The retraction movement ends, for example, in contact or at least - in the above sense - close to the contact with the top sheet B of the stack 11th

As already stated above, for moving all, one group or preferably of the single stop means 83; In principle, the drive means 99 may be configured as desired, but is preferably designed as a cylinder-piston system 99, in particular as a pneumatic cylinder 99, which can be acted upon with pressurized fluid.

For applying the pneumatic cylinder 99, the number and location of the switching means 101, in particular switching valves 101, and for their control via control means S83 (S86) of a control device, the above applies or apply accordingly.

The movement causing drive means 99, z. As the pneumatic cylinder 99, can basically directly on the output side of the holding means 299 comprehensive stop means 83 attack. Preferably, however, the drive of the stop means 83 via a gear, z. B. via a travel of the drive means 99 magnifying gear. In an advantageous embodiment, this transmission is designed as, in particular schnellschaltbares, coupling gear. For example, this is designed as a linear guide transmission based on an isosceles crank. The moving stop means 83 acts for this purpose in the direction of movement considered in at least one point with a guide 297, z. B. linear guide 297 together, so that the stop means 83 is at least at the level of this point linearly movable or is moved. In principle, a point of the stop means 83 which is viewed in the direction of movement could additionally be guided linearly by the same or a further linear guide 297. On the stop means 83 engages over a perpendicular to the direction of movement defined by the linear guide 297 pivot axis 301, a gear member 292, z. B. a coupling 292 at. Spaced from this pivot axis 301 engages over a further, parallel to the first pivot axis 301 extending second pivot axis 298 another gear member 296, z. B. a crank 296, on the coupling 292. The crank 296 is mounted on a frame 303 about one of the first two pivot axes 301; 298 parallel pivot axis 304 pivotally mounted. In a preferred embodiment corresponds to the between the first two pivot axes 298; 301 effective length of the coupling 292 of the between the second and third pivot axis 298; 304 effective length of the crank 296th

For the rotary actuator of the crank 296 or the crank coupling system can in principle any suitable drive mechanism, such as a direct rotary drive of the crank 296 or engaging a drive means 99 at a distance from the pivot axis 304 point of the crank 296th In these cases, the above-mentioned guidance of the stop means 83 at two spaced apart in the direction of movement of advantage.

In a preferred embodiment, multiple or significantly coupling in the direction of movement with the linear guide 297 can be dispensed with by forcing the coupling 292 to move to a defined movement curve when moved by the crank 296 in a coupling-fixed point spaced from the second pivot axis 298. The coupling-resistant second point of attack can basically in the two first pivot axes 298; 301 connecting connecting portion are, however, is preferably in a connecting portion beyond the second pivot point 298 in a different direction of action of the connecting portion, in particular opposite direction continuing section 307. This section 307 may be part of a prolonged over the point of the second pivot axis 298 coupling 292nd or be designed as a lever arm rigidly connected to the coupling 292 and independently of this is referred to below as the coupling 292 extending portion 307. Preferably, the coupling 292 is in this spaced coupling-fixed point via a guide 294, z. B. linear guide 294, to a rectilinear, in particular perpendicular to the direction of movement defined by the linear guide 297 and the first two pivot axes 298; 301 running trajectory, forced. The coupling 292 or the continuation of this section is in this spaced coupling-fixed point via a likewise to the first and second pivot axis 301; 298 parallel further, z. B. fourth pivot axis 306 pivotally mounted.

As mentioned above, the drive center 99 could basically act directly on the crank 296, but here preferably acts on the coupling 292, in particular on the coupling 292 extending section 307. The attack takes place z. B. via a likewise to the first and second pivot axis 301; 298 parallel further, z. B. fifth pivot axis 308 between the second and the fourth pivot axis 298; 306. Preferably, the attack of the drive takes place on at the coupling 292 and the coupling 292 extending portion 307 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. Due to these length ratios, we enable a translation of a short Antriebsmittelhubes in a large adjusting movement.

The attacking on the stop means 86 transmission can - such. In Fig. 14 and Fig. 15 illustrated - be designed and arranged such that the pivot axes 298; 301; 304; 306; 308 extend perpendicular to the transport direction T. However, it may alternatively be designed and arranged rotated by 90 °, so that the pivot axes 298; 301; 304; 306; 308 in the transport direction T run.

Although the execution of the delivery device 03 and / or sheet guiding device with an adjoining the discharge station sheet guiding element 78 with variable in its vertical position end as well as the design of the delivery device 03 and / or sheet guiding device with the or the holding means 299 comprehensive Anchor device can also be applied advantageously on its own, their combined execution has particular advantages in terms of the safe and careful transport of the printing material B (see, for. 11, 12 and 13 such as Fig. 14 ).

So shows, for example Fig. 11 the upstream end of the sheet guide element 78 in the upper position L _O , while the holding means 299 comprehensive stop means 83 in Fig. 11a ) in for the active position L _A and in Fig. 11b ) is in holding position L _H. The illustrations in FIGS. 12 and 13 show the same facts, but in Fig. 12 with in lower position L _U and in Fig. 13 with Bogenleitelementende 47.6 located in an intermediate layer L _Z ; 78th

In an advantageous development of the start-up section 78 - in principle, regardless of the above type and execution of the stop movement or vertical variability at the upstream end and / or the concrete drive configuration of the stop means 83 - movable in or on a fixed space frame G or frame part G of the dispenser 03 be stored so that it can be removed from the position occupied in the operating position and thus from the present in the operating position sheet transport path - preferably down - removable. Although it could also be mounted linearly movable for this purpose, it is preferably pivotable about a pivot axis A78 extending transversely to the transport direction out of the operating position (see, for example, FIG. Fig. 25 a) and b) , The pivoting z. Example by means of a drive means 104, which is preferably designed as druckfluidbetätigbares cylinder-piston system 104. Preferably, the drive means 104 moving the start-up section 78 can be connected and controlled by means of a signal connection with control means S78 for its activation, or be controlled by it, which in turn z. B. via a signal connection 107 with a - in particular optical - sensor 108, z. B. a photosensor 109 is connected. Through this are - for example, a corresponding signal evaluation - irregularities in the sheet run, especially a Knautschen and possibly getting stuck an incoming printing material B, recognizable.

However, it can - as in Fig. 50 by way of example with reference to the blowing device 51; 52 is shown - on the two panels 243; 244 same facilities 48; 49; 51; 52; 139 are activated for their manipulation and the corresponding screen mask is displayed.

Basically, regardless of the specific design above control and adjustment of the delivery device 03, but preferably in conjunction with the above Arrangement downstream of the second discharge station I; II or in particular the end face to the delivery device 03, wherein the delivery stations I; II each at least one z. B. above-mentioned device 48; 49; 51; 52; 103; 139 associated with an adjustment or correction of the bowing and / or -ablage by actuators 63; 106; 147; 202; 124 comprehensive drives or actuators are adjustable, is at least one control 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 operation via a first signal connection 257; 261 an actuator 63; 106; 147; 202, z. B. drive means 63; 106; 147; 202 or pressure control valve 124 to a setting device 49; 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, z. B. drive means 63; 106; 147; 202 or pressure control valve 124 a functional of the device concerned 49; 52; 103; 139 of the second delivery station II; I corresponding device 48; 51; 103; 139 of the first delivery station I; II adjustable or adjustable, in particular mitgestellt or can be set.

When setting the at least one first dispensing station I; II and one of the first delivery station I; II in the transport path downstream downstream second discharge station II; I comprehensive delivery device 03 for the delivery of printing material B is to adjust or correct the bowing and / or -ablage in the second delivery station II; I at least one adjustable with respect to an adjustment or correction of the bowing and / or -ablage in the second dispensing station II devices 48; 49; 51; 52; 103; 139 set and adjusted, and wherein as a result of and / or with the placement or setting of this device 49; 139 of the second dispensing station II also setting or setting a functional of the device concerned 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 setting a second delivery station II attributable device 49; 52; 103; 139, there is a correlated placement and / or setting, d. H. "Mitstellen", the corresponding device 48; 51; 103; 139 of the first delivery station II. The monitoring can basically be done simultaneously or possibly also with a time delay.

As a result, settings in the first dispensing station I; II, which is less visible than the second or last of the dispensing stations I; II, hit simultaneously with the second.

The pairwise affected devices 48; 49; 51; 52; 103; Although fundamentally different and / or geometrically arranged may be arranged, the specific embodiment is taken into account when the entrained size is set. Preferably, the devices 48 to be interposed are; 49; 51; 52; 103; 139, at least as regards the mechanism of the setting variable X ₉₁ ; v _from ; X ₁₃₉ ; Y ₂₀₁ , executed in the same way. As a result, no complex relationships are to be taken into account when setting but, if desired, at most an absolute and / or an offset proportional to the height of the manipulated variable.

In an advantageous development, when setting one or more of the adjustable devices 48; 49; 51; 52; 103; 139 of the rear and second delivery station I; II setting of the corresponding device 48; 49; 51; 52; 103; 139 of the first delivery station I; II using deposited rules and / or functions, which here z. 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 embodied as a tabular or functional rule 256.

The context 256 or the provision 256 is set up in particular and programmed, a measure of the setting of the first dispensing station I associated device 48; 103; 139 based on the stored relationship 256 from the in the device 49; 103; 139 to determine the second delivery station II to measure and the drive of the first delivery station I; II institution 48; 49; 51; 52; 103; 139, ie directly to the drive means 63; 106; 147; 202 or the control means S63 associated therewith; S106; S147; S202 (see eg 51 ).

Such a modification of the value over a relationship deviating from a 1: 1 application 256 - z. B. over an absolute and / or an offset proportional to the height of the control value - is preferably when setting or setting formatrelevanter, d. H. to be adapted to the respective format devices 103; 48; 49, z. B. in the lateral positions of the side stop device 103 and when setting the at least one braking device 91 in the transport direction T. It is particularly advantageous if the bodies of the device concerned 103; 48; the first delivery station I; II is done so that the setting there is an oversize in the format compared to that setting at the first dispensing station I; II for the actual format effected. Although this may suffer from the stack quality, it reduces the risk of a disruption during storage.

In contrast, for predominantly transport-relevant, ie the movement of the sheet B relevant institutions 48; 49; 139; 51; 52, z. B. for setting the storage speed v _ab to the braking device 48; 49 and / or the setting of the blowing strength at the blowing device 51, 52 and / or the release location on the release device 139 and / or the placement of the blowing devices 113q - at least as far as the target result to be achieved - are in a 1: 1-Bezieheung. In this case, the relationship 256 can directly map the 1: 1 relationship or take into account any necessary correction due to different conditions in the design.

It is particularly advantageous to use this procedure, which comprises a modification, when the second or rear delivery stations II; I supplied delivery stations I; II only serves to store waste paper. In this case, for example, less high demands are placed on the stack quality and the location of the single sheet determining devices 48; 103 can be adjusted in a more generous way. One opposite to the actual and / or the second delivery station I; II set format larger format set for the first dispensing station I; II reduces the risk of stoppers, the bow falls with greater certainty without getting stuck on the stack 11.

By actuating a first actuating means 228; 229; 231; 233; 234; 236; 228; 229; 231; 233; 234; 235; 236; 218 '; 219 '; 221 '; 222 '; 196 '; 197 '; 198 '; 199 'is or will, for example, an above-mentioned storage speed v _from a braking device 48; 49 trained device 48; 49 and / or an above-mentioned release location of a device 139 embodied as a release device 139 and / or a lateral position of a stop means 202 of a device 103 configured as a side stop device 103 and / or an above-mentioned position of a brake device 91 as a braking device 48; 49 trained device 48; 49 and / or a blowing action of one or more blowing devices 113q of a blowing device 51; 52 formed device 51; 52 both the second and at the same time the first dispensing station I; II changes or is changeable.

1. A delivery service (03) having at least two deposition stations (I ; II) and having a conveyor system (21), through which a sheet of printed material (B) can be received and can be conveyed downstream to a first of the deposition stations (I; II), where it can be deposited for the formation of a first stack (11) or can be further conveyed downstream to the second of the deposition stations (II; I) and can be deposited there for the formation of a second stack (12), wherein each deposition station (I; II) is assigned to a vertically movable support device (36; 37) for direct or indirect reception of a stack (11; 12), characterized in that in each case a stack changing device (53; 54) facilitating an interruption free stack change with an auxiliary support device (166; 167) that can be lowered by means of a motor is assigned to the first and the second deposition stations (I; II).
2. The device according to claim 1, characterized in that blowing air openings (114r) of a blower device (51) are provided above the first stack delivery means (I), which are combined into several groups (113q) or parent groups of groups (113q) running transversely to the transport direction (T) and the groups (113q) or parent groups can be activated or deactivated respectively via at least one assigned valve (116).
3. The device according to claim 2, characterized in that the one or a plurality of blowing air openings (114r) are line connected to a compressed air source (119) via one or more switchable valves (116), which in the case of an opened valve (116) on their inside applies a pressure to the blowing air openings (114r) that is more than 0.6 bar above normal pressure.
4. The device according to claim 1, 2 or 3, characterized by a conveying system (21) comprising a holding device (32), through which a sheet of printed material (B) can be received and can be conveyed downstream to a deposition station (I; II), where it can optionally be released from the holding device (32) and can be deposited on a stack (11, 12) to be formed or can be further conveyed downstream, and with a switching device (141, 142) causing the release, which comprises a switching cam (141) functionally and/or spatially assigned to the deposition station (I; II) and a cam follower (142) functionally and/or spatially assigned to the holding device (32), wherein for its actuation the cam follower (142) acts on at least one holding element (56) of the holding device (32), wherein the switching cam (141) for activation and for deactivation of the released by a first control device (143) comprising a first drive means (146) engaging on the switching cam (141) can optionally be brought in and out of the undisturbed movement path (152) of the cam follower (142), and wherein a contact point on the switching cam (141) for the first contact between the switching cam (141) and the cam follower (142) moving in transport direction (T) can be varied by means of a second control device (144) comprising a second drive means (147) along the transport direction (T).
5. The device according to claim 4, characterized in that the switching cam (141) is variable in its distance to the movement path of the cam follower by means of the second control device (144) through variation of the contact point with at least one of its ends with respect to the transport direction (T).
6. A method for operating a delivery device (03) having at least two deposition stations (I; II) and having a conveyor system (21), through which a sheet of printed material (B) can be received and is conveyed downstream to a first of the deposition stations (I; II), where it is either deposited for the formation of a first stack (11) or is further conveyed downstream to the second of the deposition stations (II; I) and is deposited there for the formation of a second stack (12), characterized in that both on the first stack (11) and on the second stack (12) upon reaching a predetermined or maximum stack height or at the instigation of the service personnel an interruption-free stack change takes place by temporarily introducing an auxiliary support device (166; 167) for the formation of an auxiliary stack (168; 169) in the descent path of the sheets of printed material (B) and lowering it by means of a motor correlated to the growth of the auxiliary stack (168; 169) caused by the continuation of operation.
7. The method according to claim 6, characterized in that the sheets of printed material (B) are deposited at the first of the deposition stations (I; II) either as waste sheets for the formation of a waste sheet stack (11) or are further conveyed downstream to the second of the deposition stations (II; I) as good sheets and deposited there for the formation of a good sheet stack (12).
