The operating modes m1; m2 can be found in the speed profile for the holding means 92 and / or in a profile for the activation / deactivation of the holding means 92 differ. Operation in one of the operating modes m1; m2 takes place in each case at least for the duration of one cycle length, wherein the cycle length is based, for example, on the machine and / or printing material phase position and z.

In the case of an automated decision, this can be done on the basis of a measurement or a preset sequence of copies. For example, so-called. Waste paper copies manually or in a defined number to the respective stack 11 ; 12 be delivered. In the case of formation of several so-called good-bow stacks, the decision on the levy can be made by assigning the signatures to the individual stacks 11 ; 12 be taken or be.

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

In the advantageous embodiment of the dispenser 03 with several, in particular two stacks 11 ; 12 or dispensing stations I; II is each of the dispensing stations I; II a braking device 48 ; 49 upstream. Their drive 106 is so operable or operated, so that cooperating with the arc B effective area 112 of the holding agent 92 in at least part of the contact time between holding means 92 and bow B with respect to the currently available, through the conveyor system 21 certain conveying speed v32, z. B. a speed of the holding devices 32 gripper carriage speed v32, lower, z. B. operated by at least 50% lower storage speed v _ab and / or operable. In a preferred embodiment of their drive 106 is so dynamically operable, so that cooperating with the arc B effective area 112 of the holding agent 92 at least between the currently available, through the support system 21 certain conveying speed v32, z. B. a speed of the holding devices 32 gripper carriage speed v32, and a lower, z. B. is at least 50% lower storage speed v _from continuously variable.

A printing material sheet B _{n to} be deposited is on the input side of the braking device 48 ; 49 by a holding means 92 the braking device 48 ; 49 taken, in particular pneumatically sucked, which is at or near with, ie more than 95%, the conveying speed v32, ie without or almost no relative movement between the holding device 32 of the conveyor system 21 and the holding means 92 the braking device 48 . 49 , moved in transport direction T. After opening the holding device 32 is done, ie for example after gripper opening, the speed v92 of the holding means 92 reduced by speed change to the lower deposition speed v _ab , thereby braking the sheet B and finally on the stack 11 stored.

This - especially for the first brake device 48 and the second brake device 49 - Reduction of the speed or deceleration taking place for storage in the relevant operating mode m1 preferably takes place along a predetermined curve, the course of which may advantageously be modifiable and / or parameterizable via appropriate 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. In this case, at least the height of the above-mentioned depositing speed v _ab , ie the lower end speed present after the lowering, can be changed by operating personnel.

Instead or preferred in addition to this, the position of the braking device 48 ; 49 in the transport direction T, in particular the position of the or the holding means 92 , changeable by the operator.

A not to be deposited, ie to be transferred sheet B _{n + 1} is also the input side of the braking device 48 ; 49 by a holding means 92 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 device 32 of the conveyor system 21 and the holding means 92 the braking device 48 . 49 , moved in 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 brake device 48 ; 49 has left or is just leaving. The continue through the holding device 32 of the conveyor system 21 held bow B is downstream of the braking 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 in the printing material path 48 ; 49 upstream or downstream, which is operable in two different operating modes and / or operated or is. 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 speed of the drive changes 106 abzulegendem each sheet at least once from a first speed v effecting _a speed which 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 consecutive sheets B _n are to be deposited one after the other, then this first operating mode m1 is repeated correspondingly often so that the braking device 48 . 49 ie the holding means 92 , the speed v92 between conveyor speed v32 on storage speed v _from and back again in time with the incoming and to be deposited sheet B _n changes.

When changing to storage speed v _from the speed v92 of the holding means 92 during the active contact with the conveyed sheet B preferably lowered 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 speed v92 of the holding means corresponding to the conveying speed v32 92 is in stationary operating situation about 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 braking, 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 , for example, takes place in the sheet path s only in a phase in which the front edge 109 of the sheet to be filed B _{n + 1} ; B _P only less than half an arc length from the escape s2 to the downstream stack edge or the leading edge 111 of the sheet to be filed B _{n + 1} ; B _{P is located} only less than half an arc length from the escape s1 to the upstream stack leading edge.

In the second operating mode m2, z. A guide mode m2, in which one or more sheets B over the first stack 11 , z. B. waste stack 11 , or the dispensing stations I are to be led away, is the drive 106 over at least the entire phase of the contact between the braking device 48 . 49 ie the holding means 92 , and that over the stack 11 or the dispensing station I wegzuführendem sheet B operated at a speed which at the holding means 92 causes a substantially the conveying speed v32 corresponding speed v92. If there is a constant conveying speed v32, this is also constant at least during the above-mentioned contact phase. 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 via appropriate switching means 107 clocked activatable and deactivatable holding means 92 intended. For clocking is the switching means 107 For example, with control means S107 in signal connection, which is designed and set up to activate and deactivate the holding means 92 synchronized 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-position-related velocity profile, but also in the switching profile for the wiring, ie activation and deactivation, of the or the holding means 92 ,

In the first operating mode m1 becomes the holding means 92 deactivated in the entire or in at least part of the positive acceleration phase of the storage speed v _down to the conveying speed v32. In the version as suction elements 92 In this phase, suction is at least temporarily stopped, ie the application of a negative pressure p on the suction element 92 interrupted.

In the second operating mode m2, the activation of the holding means 92 over at least the entire phase of the contact between the braking device 48 . 49 ie the holding means 92 , and that over the stack 11 or the dispensing station I wegzuführendem bow B maintained. Preferably, the suction or the negative pressure p remains ^{- maintained} over the entire cycle. In the version as suction elements 92 remains in at least this contact phase, the suction turned on, ie, the negative pressure p on the suction element 92 maintained. Preferably, the suction or the negative pressure p 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 range 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. Are several consecutive sheets B _{n + 1} ; B _{n + 2 to} successive transfer, the suction or the negative pressure p may remain switched on over the duration of the respective 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 to be transferred stack 11 . 12 spans. This results in a "break-in" of the sheet to be transferred B _{n + 1} in the storage shaft of the stack to be transferred 11 prevented 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 rules for the generation of setpoints for the speed v92 of the holding means 92 maintained. 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.

The regulations in this case in each case comprise different assignment rules between the current conveying speed v32 and a desired value or course of the desired speed for the speed v92 of the holding means 92 , For the assignment rule of the second mode of operation m2, as a relationship, at least for the duration of the contact with the sheet B, a course of the flow proportional to the conveying speed v32 is Holding means speed v92 and provided 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.

During operation of the dispenser 03 For example, in a set-up several, z. B. n (n ε N), bow B _i (i = 1 ... n) - in particular using the operated in the first operating mode m1 sheet brake 48 - In the area of the first discharge station I as waste on a first stack 11 stacked. At least one subsequent to the n arc bow _{Bn + 1} is z. B. as a sample sheet or as a good sheet - especially using the operated in the second mode of operation m2 sheet brake 48 Via the first delivery station I or the first stack 11 away and downstream of another dispensing station II or a sheet removal device 87 fed. After, for example, a predefined number of setup sheets have been supplied as waste to the first delivery station I and / or, for example, a sample sheet has been found to be good, it is converted automatically or manually to a production operation in which the sheets B _{i are} regularly in the stack of good sheets 12 be filed. During the production operation, however, for different reasons it may happen that one or more sheets B _P - in particular using the sheet brake operated in the first operating mode m1 48 - the first or waste stack 11 are to be supplied. This can be, for example, when changing the pile incurred alternating sheet or faulty or damaged bow. Such, auszuschleusender during the production sheet B _P can be triggered manually or by a sensor or be.

For controlling the at least one of the holding means 92 driving drive 106 and / or the at least one of the holding means 92 activating switching means 107 is the drive 106 and / or the switching means 107 in signal communication with control means S106; S107, in turn, for example, in signal communication with a signal generator, eg. As a sensor or a drive master is, from which they receive the machine and / or printing material phasing and / or representing information I (Φ). The control means S106; S107 comprise a control circuit and / or an algorithm arranged to be connected to the operating modes m1; m2 explained control of the drive 106 and / or switching means 107 to effect.

That in terms of the execution of the braking device 48 ; 49 It is also to be applied that so-called good-bow B _{n + 1} in the first or the second delivery station I; II and so-called waste sheet B _n ; B _P in the other dispensing stations II; I are to be stored or filed. In this case, under waste sheet B _n ; B _P Setup sheets, faulty rejects sheets or sheets to be manually selected by the staff. For example, the waste sheets are or will be on a stack 11 stored in the area of the first dispensing station I and credit in the area of the second dispensing station II. The above procedure and / or control of the braking device 41 ; 42 However, it can also be provided for the application in reverse assignment of waste paper and good sheet, as well as in connection with the formation of several, each of waste paper stock different from waste.

This may for example be a sheet guiding element, which z. B. by the correspondingly high-carrying device 36 ; 37 itself a arranged on this sheet guide means, for. B. baffle is formed. For example, for the second operating mode in the relevant dispensing station I, the carrying device 36 ; 37 by vertically positioning in a transport path near, z. B. the highest possible, location spent. In addition to this, before, during or after reaching this position, a named sheet guiding means can be set up or inserted.

As already indicated, the start-up section has 78 in the region of its upstream end a run-on slope with preferably a rounded edge 84 , in particular upper edge 84 , on. This is the basis of the conveyor system 21 facing, substantially flat guide surface 79 the start-up section 78 in a bent down, z. B. rounded contact surface 81 continued. Under the substantially flat guide surface 79 should in addition to actually flat surfaces and slightly curved surfaces with a radius of curvature of z. B. throughout at least 1,000 mm, in particular at least 3,000 mm, to be understood. The rounding of the edge 84 is z. B. such that the edge 84 is rounded in the manner that a in a direction in the transport direction vertical section considered course of the top between a first, in the region of the still flat or slightly inclined guide surface 79 lying point to a second point at which an inclination of the tangent to that at the first position is 45 °, at least a radius of 50 mm and / or that has a profile of the edge 84 between the end of the planar or at least substantially planar guide surface 79 and a perpendicular to the course of this plane calculated by 50 mm spaced point in the contact surface 81 at each point a radius of curvature of at least 5 mm, preferably of at least 10 mm, and preferably a maximum radius of curvature of z. B. 500 mm, in particular 200 mm. The radius of curvature here must not be constant in the considered section but can vary. A possibly the aforementioned rounded contact surface 81 In principle, the comprehensive limb can be realized in the transverse direction, ie in the direction of the width of the delivery device, continuously, in regions, or in several parts (see, for example, FIG. 8th ). The expression of the "plane guide surface" is intended to include below the above case of a slightly curved surface.

As an "edge" 84 the start-up section 78 in the above sense, here is the upper corner of the start-up section 78 be understood, whether he z. B. by the rounded corner of a solid component or z. B. is formed by a bent down sheet metal.

Preference is given in or before the vertical alignment of the contact surface 79 and below through the guide surface 79 given height lifting gear 81 a stop device is provided, which limit the movement to be deposited in the first discharge station I sheet B in the transport direction T. At these slings 82 becomes the downstream stacking edge of the stack to be formed 11 educated. In addition to this, movable stop means 83 be provided, which by a drive device 64 with at least one drive means 99 in a first, z. B. active operating state over the through the guide surface 79 protrude given height and in a second, z. B. inactive operating state are arranged below this level. In a little elaborate design, several of the stop means 83 be moved or moved together, for example via a connection or shaft. The start-up section 78 can be in the area of its guiding surface 79 and / or in the area of its contact surface 81 and / or in the area of its rounded edge 84 Air passage openings 68 ; 69 , in particular blowing air openings 69 or air-blown air passage openings 69 , exhibit.

In a first preferred embodiment of the starting section 78 this includes in the area of the rounded edge 84 ie, in an upstream of the planar guide surface 79 subsequent curved surface section 84 , a blowing device with one or preferably a plurality of blown air openings 97 , The blown air openings 97 can be through round or preferably slot-shaped recesses 97 in one the rounded edge 84 forming material section 84 , in particular sheet metal section 84 formed and from the interior of the start-up section 78 forth, ie from the side of the material section facing away from the printing material transport 84 be supplied with blast air. The blast air supply can be through a on the inside inside of the material section 84 be formed subsequent air box.

In a preferred embodiment, the blast air supply is provided by a blast air duct running transversely on the inside of the material section 98 formed, the wall in turn corresponding to the Blasluftöffnungen 97 arranged outlet openings comprises. The blast air line 98 is preferably at least in the region of the material section 84 facing side formed with a corresponding to the inside of the material portion shape. For example, the blown air line 98 as a blowing tube with a circular outer peripheral cross-section and the material portion 84 at least in the area of his blast air duct 97 opposite section in cross-section circular arc. The in the material section 84 provided Blasluftöffnungen 97 have at least one in the direction of movement over the start-up section 84 guided printing material sheet extending direction opposite the outlet openings larger opening cross-section. This ensures, for example, a secure passage of air.

In a particularly advantageous development, the preferred tube-like blown air line 98 be mounted pivotably about a transverse axis. This can be, especially when compared to the outlet openings in the above manner larger Blasluftöffnungen 97 , At least slightly adjust the position of the Blasluftaustrittes along the sheet movement direction.

The so-called start-up section 78 can basically be independent of the execution of the dispenser 03 with several 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.

Normally, it only sinks at the leading edge through the conveyor system 21 or the holding device 32 , in particular the holding elements 56 guided sheet B 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 stacking level - lead to a harmful level jump. In this case, the natural air cushion can not, the bow B as a wing over this stage on the following sheet guiding 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). Instead of this or in addition to one or more of the measures mentioned is 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 included or this upstream start-up section 78 , this or this or at least its guided bow B 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 start-up section 78 is in height to the variable stacking level, ie the height of the top 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. This is the driving means included in the actuator 283 , In particular its control device or drive controller, in signal connection to a vertical position of at least the end of the sheet guiding element 78 as a function of and / or correlating with the stack level, the control means.

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. 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 above assumed for the print run working height and / or if at the beginning of stacking the working height, ie the ideally in the above-mentioned printing level of the top sheet layer, 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. 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. Basically, one or both sides of these two limits ( Lage L _O and Lage L _U ) Beyond layers be driving, but which are approachable, for example, for set-up or maintenance or other non-operational actions.

The start-up section 78 is executed by said variability and / or stored such that it is also for compared to the maximum or in-pressure taken stack level reduced levels, the current stack level with the higher, preferably horizontal sheet guiding level, ie by the course of the Conveyor system predetermined levels, connects. Here, the "stack level" is understood to mean the vertical position of the upper stack end.

As drive 283 is for example an engine 283 , in particular an electric motor 283 provided, which z. B. via a transmission 284 medium or directly on the sheet guide 47.5 ; 78 or start-up section 78 attacks. As a transmission 284 can advantageously a spindle drive 284 be provided by the engine 283 driven threaded spindle 286 in a middle or directly with the sheet guide 47.5 ; 78 or the start-up section 78 connected storage block 287 intervenes. In principle, the drive for varying the position of only one side by only one actuator with motor 283 or from two sides by one actuator with motor 283 respectively. In an advantageous embodiment, the positioning is carried out by an actuator with only one motor 283 but from two sides. For this purpose, for example, both sides medium or directly at the start-up section 78 attacking gears 284 provided, whose movement is mechanically, for. B. via a shaft 291 , is synchronized. The two synchronized drive trains of the actuator are by a motor 283 at any point, for example, on one of the two sides, driven.

The sheet guiding element 47.5 ; 78 or that the sheet guiding element 47.5 ; 78 in the vertical position varying drive means 283 can be manually adjustable, for example, via controls not shown here. Instead or advantageously in addition to this is the sheet guiding element 47.5 ; 78 or that the sheet guiding element 47.5 ; 78 in the vertical position varying drive means 283 preferably automatically adjusted via control means adjustable, preferably - at least in an operationally provided adjustment range or a subregion - correlated to the vertical position of the stack top in the upstream stacking space 44 ; 46 adjustable. In operation, thus, the vertical position of at least the upstream end of the run-up section 78 correlates to the vertical position of the stack top in the upstream stack space 44 ; 46 varied. Here, the vertical position of the upstream end and the drive means 283 For example, controllable in dependence on the position of the stack top information representing. Instead or in addition thereto, the vertical position of the upstream end or the drive means 283 in conjunction 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 side of the starting section 78 a sensor which detects the upper stack edge may be provided.

The sheet guiding element 78 is in the delivery device 03 Preferably arranged and / or stored such that at lying within the operationally provided adjustment range variation of the vertical position of the upstream end of the sheet guiding element 78 each of the upstream stacking space 44 ; 46 perpendicular to the transport direction T facing end face of the sheet guiding element 78 to lie 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 guiding element 78 equivalent. 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 points of the upstream end via an actuator which is directly on or at least near the end to be moved at the starting section 78 attacks and the start-up section 78 shifted at the point of attack along a vertically extending rectilinear motion.

In an advantageous embodiment, the sheet guiding element 78 or the z. B. as a starting sheet 78 named start-up section 78 designed and / or stored in an advantageous embodiment, 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 persists. 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, a transition to a subsequent section or sheet guiding element can be made 47.5 regardless of the vertical position of the upstream end in the above sense be kept quasi-continuous.

In the event that the above-mentioned variation of the height of the upstream end is provided along the above-mentioned, substantially vertical line as well as a maintenance of the level at the downstream end, is a guide device with a frame-fixed stop means 288 provided with a start-up portion fixed, in particular in a closer to the downstream end than the upstream end closer to the starting portion 78 provided slings 289 for the defined position assumption of the downstream end of the starting section 78 works together.

The lifting gear 288 ; 289 are designed such that in 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 47.5 effective guidance surface 79 maintains the level in the above-mentioned manner. 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 comprises 288 such a curve at which the z. B. as a role 289 trained stop section fixed stop means 289 runs along. The starting section fixed stop means 289 can from below through the frame-tight sling 288 be supported, where - among other things - the gravity ensures a secure contact. Conversely, the starting section fixed stop means 289 from below against the corresponding, frame-fixed stop means 288 be pressed. In this case, this can either be static over a start-up section 78 attacking spring element or be effected via a drive means or be, by which z. B. the corresponding stop means 288 ; 289 optionally in contact with each other and out of contact can be brought. In the embodiment with an embodiment set forth below, a start-up section which can be swiveled away with the downstream end in the event of a fault 78 this can be done at the start-up section 78 attacking and for contact between the corresponding slings 288 ; 289 providing drive means by the swiveling effecting drive means 104 be formed.

Preferably, the thus variable in its vertical position starting section 78 at the beginning or at the upstream end of one between two delivery stations I; II arranged conveyor line provided. To the downstream end of the start-up section 78 may be a preferably horizontally extending portion of the same sheet guide or a preferably horizontally extending further sheet guide 47.5 connect. In a further variant, the sheet guiding device on the between two discharge stations I; II lying conveyor line with the upstream end of the start-up section 78 end up.

The as a starting sheet 78 named start-up section 78 can be multi-part, z. B. may be formed of several adjoining baffles. In this case, the Leitkontur the start-up section 78 put flat and curved sections together. In an advantageous embodiment, the starting section comprises 78 in the area of the guide surface 79 and / or in the region of the bent edge 84 og air passage openings, in particular Blasluftöffnungen 69 ; 97 having. For this purpose, the start-up section 78 in the manner described above, for. 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 abovementioned stop means be designed such that a plurality of transversely juxtaposed stop means 83 ; 86 individually or at least in several groups by a corresponding number of drive means 64 or drive means 99 movable between the active and inactive positions, e.g. B. pivotable or z. B. are translationally movable.

To move all, one group or preferably the single stop means 83 ; 86 can the drive means 99 basically be executed arbitrarily. However, it is preferred as acted upon with pressurized fluid cylinder-piston system 99 , in particular as a pneumatic cylinder 99 , executed.

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

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

Switching the valves 101 takes place, for example synchronized and / or in a correlation to a machine and / or printing material phase position of control means S83 (S86) of a control device forth, for example, in signal communication with a sensor or a master, of which they concern the machine and / or printing material phase position and / or representing information I (Φ). 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 slings 83 ; 86 takes place for. 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 above, in the area of the edge 84 integrated blowing device, for example, activates and deactivates a blown air supply in dependence 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 an advantageous embodiment of the starting section 78 are in the guide area 79 and / or in the guide surface 79 continuing surface of the sheet guiding element 41.5 blast-air 69 , in particular in the manner of venturi nozzles 69 , intended.

In a first embodiment, for example, as a stop means 83 swiveling stops 83 be provided. In this case, the movable, in particular pivotable stops 83 in the upstream end of the start-up section 78 integrated and / or arranged on this. Here, the guide surface 79 z. B. recesses 102 on, in which, for example, formed in the first embodiment attacks 83 are retractable in the inactive state.

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

Furthermore, in a variant of the embodiment not shown here, the pivotable stop means 83 comprehensive stop device mechanical holding devices in the assembly of the starting section 78 be integrated, which already hold down in the upstream dispensing station I printed material sheet B, while subsequent printing material B are transferred to another dispensing station II or a sampling point. Such a holding device is z. B. in the event of an intended re-storage of another sheet B on the stack 11 . 12 the upstream dispensing 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 changing files from the first to the next batch 11 ; 12 , z. B. the waste stack 11 on the good sheet stack 12 , those are for filing on the first batch 11 necessary, the bow B catching slings 83 brought out of trajectory of the sheet B, for the transfer of printing material B, z. B. Gutbogen to have a free passport room available. However, the problem may arise that -. 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. as a gripper carriage 32 trained holding devices 32 , which promote the bow B at full speed, a drift arises, which can lead to the entrainment of the Ries or single bow B in the end.

To counteract this are one or more attacks 83 - As in the first embodiment set forth above - be designed and movably mounted so that they are in the active state, ie in an active position, in the trajectory of the printing material B and this with the leading end of the sheet facing side, z. As an abutment surface, are effective as a front stop, and in the inactive state, ie inactive position, moved out of the trajectory B printed stock, so are arranged outside the trajectory, and for the incoming printing material B without impact effect. In addition to this is the one or more of the movable stop means 83 one with the movement of the sling 83 forcibly moved and in at least one inactive position of the sling 83 over the stop surface in the direction of the incoming printing material B protruding holding means 299 assigned, which in inactive position of the sling 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 comes 299 in the active position of the associated stop means 83 downstream and / or above the trajectory of the stack 11 to be submitted to the substrate sheet B and inactive position of the associated stop means 83 below the trajectory of the over the stack 11 to be further promoted substrate sheets B and over the top B of the stack 11 to lie.

The sling 83 associated holding means 299 thus keeps inactive sling 83 the topmost layer of the pile 11 down against lifting and / or entrainment by subsequently to be transferred to printing material B. In this case, the holding means 299 in Haltelage 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 overlap in the transport direction T.

The assignment of the holding means 299 can be realized in a preferred embodiment such that an inactive position upper part of the stop means 83 the holding means reaching upstream over the stack edge 299 includes. Alternatively, could also be a holding means 299 - rigid or via a mechanical coupling - so with the stop means 83 be connected, so by movement of the sling 83 forcibly the required movement of the holding means 299 takes place and / or vice versa with movement of the holding means 299 the relevant movement of the lifting gear 83 ,

Basically, regardless of the specific design above control and adjustment of the delivery device 03 , but preferably in connection with the above-mentioned arrangement downstream of the second delivery station I; II or in particular frontally to the delivery device 03 wherein the dispensing stations I; II each at least one z. B. above-mentioned device 48 ; 49 ; 103 ; 139 assigned to the dispensing stations I; II at least one institution ( 48 ; 49 ; 103 ; 139 ) associated with respect to an adjustment or correction of sheet guiding and / or storage by drive means 63 ; 106 ; 147 ; 202 comprehensive drives are adjustable, is at least one user 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 ; 236 ; 237 ; 238 ; 241 ; 242 provided by its operation via a first signal connection 257 ; 261 a drive means 63 ; 106 ; 147 ; 202 an institution to be provided 49 ; 103 ; 139 the second delivery station II; I and a second signal connection 258 ; 262 a drive means 63 ; 106 ; 147 ; 202 a functional of the institution concerned 49 ; 103 ; 139 ) of the second delivery station II; I corresponding facility 48 ; 103 ; 139 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 display device 03 for the delivery of printing material B is to adapt or correct the bowing and / or -ablage in the second delivery station II; I at least one with regard to an adjustment or correction of the bowing and / or -ablage adjustable in the second dispensing station II facilities 48 ; 49 ; 103 ; 139 and due to and / or with the placement or setting of this facility 49 ; 139 the second dispensing station II also a setting or setting a functional of the device concerned 49 ; 103 ; 139 the second delivery station II corresponding device 48 ; 103 ; 139 the first delivery station I; II takes place.

When setting and / or setting a second delivery station II attributable device 48 ; 103 ; 139 a correlated setting and / or setting of the corresponding device takes place 49 ; 103 ; 139 the first delivery station II.

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 device 48 ; 49 ; 103 ; 139 may in principle be different and / or geometrically arranged, wherein the location of the entrained size then the specific design is taken into account. Preference is given to the device to be put together 48 ; 49 ; 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, one or more of the adjustable devices is set when setting 48 ; 49 ; 103 ; 139 the rear and second delivery station I; II setting or setting the corresponding device 48 ; 49 ; 103 ; 139 the first delivery station I; II using deposited rules and / or functions, which here z. B. generally as deposited context 256 is designated. This connection 254 is for example in circuit and / or data processing means 254 deposited and can be used as a tabular or functional rule 256 be executed.

The relationship 256 or the rule 256 In particular, it is set up and programmed to provide a measure of the setting or setting of the device assigned to the first dispensing station I. 48 ; 103 ; 139 based on the stored context 256 from the one in the facility 49 ; 103 ; 139 to determine the second delivery station II to be set level and the drive of the first discharge station I; Institution concerned 48 ; 49 ; 103 ; 139 ie directly to the drive means 63 ; 106 ; 147 ; 202 or the control means S63 associated therewith; S106; S147; S202 (see eg 49 ).

Such modification of the value over a relationship other than a 1: 1 application 256 - z. B. on an absolute and / or proportional to the height of the control offset - is preferably when setting or setting formatrelevanter, ie adapted to the respective format devices 103 ; 48 ; 49 , z. B. in the lateral positions of the side stop device 103 and in setting the at least one braking device 91 in the direction of transport T. It is of particular advantage when the bodies of the institution 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 bow B relevant institutions 48 ; 49 ; 139 , z. B. for setting the storage speed v _from the brake device 48 ; 49 and / or placing the release location on the release device 139 - at least as far as the job results are concerned - in a one-to-one relationship. This can be the context 256 mimic the 1: 1 relationship directly or consider 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 stringent requirements are imposed on the stack quality and the location of the single-sheet determining devices 48 ; 103 can be adjusted in a more generous way.
