EP3463885B1 - Delivery device of printed sheets and method of operating it - Google Patents

Description

The invention relates to a delivery device and a method for operating a delivery device according to the preamble of claims 1 and 13, respectively.

In a section on the flow of materials and data in " Handbuch der Printmedien "by Helmut Kipphan, Springer Verlag, 2000, is shown in Fig.8.1-11 (Chapter 8.1 ) set out a double delivery as a "highly automated variant of the non-stop boom". Furthermore, double brackets can also be used to separate waste sheets as so-called waste switches.

In the JP 25 17 276 B2 discloses a delivery device with two delivery stations, a guide element being provided between the first and second delivery stations. In the end area, a stop which can be pivoted into and out of the transport path is provided.

The DE 10 2008 006 528 A1 discloses a device for discharging sheets, wherein a sheet to be discharged can be discharged downward from a guide plane having blown air openings upstream of the main stack. For this purpose, in one embodiment, a combing rake, which otherwise continues the guide surface, is pivoted into the transport path around the sheet downwards the management level to an auxiliary stack. A guide piece adjoining the diversion point has blown air openings.

Similarly, the DE 103 29 833 A1 a sheet guiding device with a part which can be swung downwards, via which sheets to be discharged as waste can be fed to a so-called waste stack. The sheets are transported by grippers, which are opened at the point of delivery by contact with an opening curve. The curve provided above the waste stack can be pivoted in and out of the transport path of the gripper opening mechanism. Furthermore, a blowing device is provided above the waste stack, which acts on the top of the sheet. A guide surface adjoining the pivotable part of the guide level can be operated by a fan with overpressure or underpressure.

One on the home page of Koenig & Bauer AG via the address http. // www.kba.com / bogenoffset / bogenoffsetmaschinen / product / rapida-106 / detail / accessible brochure for the "Rapida 106" a page is disclosed on pages 26 and 27, in which a so-called Venturi sheet guide is used.

The DE 10 2012 206 929 A1 discloses a sheet brake with a suction band, the deceleration of which slows down the sheet. After opening the gripper, the speed is reduced from the gripper carriage speed to a depositing speed. The curve opening the gripper is adjustable. The drives for the brake elements and for setting the gripper curve can be made via the machine control.

Through the DE 10 2009 027 633 A1 discloses a blown air device with at least one blown air tube extending in the transport direction and with fan elements. The blowing effect in the central area of the falling bends can be influenced in a targeted manner with the blowing air pipe. An application is preferably made in time with the sheets arriving from the printing press.

The EP 1 958 906 A2 relates to a sheet guiding device in a stack delivery device comprising two delivery stations. A blowing device comprising several fans is assigned to the first delivery station. The fans are opened for the operating state in which a sheet is to be fed onto the second stack the suction side covered by inserting a sign. The delivery of the sheet at the delivery station is controlled via a gripper opening curve, which can either be introduced into the movement path of the gripper opening mechanism or can be removed from it again.

In the DE 103 29 833 A1 A delivery device with means for forming a waste stack and a good sheet stack is disclosed, with a gripper opening curve above the first-mentioned stack being able to be swung into and out of the movement path of a gripper bar to activate or deactivate the sheet release.

In the DE 10 2008 020 533 A1 discloses a blowing air device over a stacking shaft of a sheet delivery. By means of adjustable baffle surfaces of an air guiding device, the blown air can either be deflected from the sheet transport path or can be set to act on the sheet. In operation, the air guiding device is adjusted by a control unit in time with the sheet sequence so that it is permeable in the transport direction in front of the sheet leading edge in the closed position and after the sheet leading edge in the open position. The DE 693 07 840 T2 discloses a delivery device with a delivery station and a switching device effecting the release with a switching cam and a cam follower functionally assigned to a holding device. The switching cam is arranged to adjust the opening point on a base plate which is movably mounted with respect to the machine frame along the transport direction. To activate and deactivate the sheet release, the switch cam is pivoted about a pivot axis provided on the base plate via a type of toggle lever mechanism.

Through the DE 103 54 673 A1 A display for forming only a stack is known, the location of the release of a sheet being determined via the location of the first contact. A switching cam in a first position releases sheets above the stack. By means of a switching cam located in a second position with a later initial contact, sheets are still passed over stacking stops for the purpose of sample sheet removal and are only released for contact with a sample sheet stop. The location for the first contact is set by pivoting the switching cam by means of a drive means designed as a pneumatic cylinder. The DE 102 05 213 A1 relates to a delivery with a stack delivery, wherein flat printing materials can be conveyed to a delivery by a gripper system and deposited there to form a stack. To eject waste or sample sheets, a sheet is conveyed over the delivery and passed behind it to a suction belt conveyor. The handover is extremely sensitive to deviations from the optimal relative position of the gripper system and suction belt. In order to be able to compensate for tolerance deviations or to allow adjustment to different substrate thicknesses, the suction belt is arranged in a vertically movable manner via a spindle drive in different grid positions.

Through the DE 199 05 263 C1 discloses a collecting device of a delivery device for test sheets, the sample sheets being held on sheet supports of the collecting device by clamping fingers.

The DE 196 31 598 A1 discloses a sheet guiding element in a delivery of a printing press with blown air openings, which is provided in the transport path upstream of the stacking space.

Through the EP 1 489 031 A2 A sheet guide of a double-stack delivery is known, wherein when a sheet is transferred over the first stacking space, a guide rail of a guide device from the downstream over the to transferring stacking space is spent. This enables flutter-free transport of the sheets to be transferred.

Also the JP 2006 036511 A discloses a sheet guide, wherein a guide aid can be brought from downstream over a stacking space to be transferred EP 0 845 431 A2 relates to a non-stop delivery device, an auxiliary stack pad being inserted from behind when changing the stack above the stack to be removed. In order not to move the uppermost layer of the stack upstream, an actuating device is activated in a sensor-controlled manner when the auxiliary stack support is pushed in, so that a hold-down fixes the uppermost sheet of the main stack.

The DE 42 13 032 A2 relates to a device for sample sheet removal, in preparation for the sample sheet removal an auxiliary stop is placed on the currently top stack sheet, on which the incoming sample sheet comes to rest and can be removed from the support fingers supporting the subsequent sheets after insertion.

The invention has for its object to provide a display device and a method for operating a display device.

The object is achieved by the features of claims 1 and 13 respectively solved.

The advantages that can be achieved with the invention are, in particular, that particularly low-interference operation and / or transport that is as gentle as possible and / or high quality storage is achieved for a storage device for sheet-shaped printing materials.

It is particularly advantageous that the disturbances associated with the increased speed when transferring sheets can be minimized. This can be, on the one hand, the dragging of already deposited sheets by the resulting air currents and, on the other hand, striking at high speed against an adjoining sheet guide element, in particular if the fastest possible start is to take place with the stacking plate possibly not yet fully raised.

In a preferred delivery device for a sheet-processing machine with at least one delivery station and a conveyor system, by means of which upstream processed printing material sheets can be picked up at a takeover location, can be conveyed to the delivery station via a first conveying section and can optionally be delivered to a stack or can be further conveyed there therefore a holding device holding down the uppermost sheet of the stack during the transfer of a sheet to be conveyed against entraining and / or lifting is provided with one or more holding means spaced apart from one another transversely to the transport direction. According to the invention there is provided a sheet guiding element which adjoins the delivery station and which can be varied in its vertical position by an actuator with at least its upstream end.

With a vertically movable, in particular vertically moved, sheet guiding element in the transport path behind a first sheet deposit, the risk of damage to a to be transferred significantly reduced. The transition is as smooth as possible. With a holding device provided for itself or in addition to the vertically movable sheet guiding element, in particular when the machine is running quickly, the sheet which has already been deposited is prevented from being carried away.

In a preferred embodiment of the delivery device with a conveyor system, through which a printing material sheet can be picked up at a takeover location and can be conveyed downstream to a delivery station comprising a stacking space, where it can either be delivered from the conveyor system to a stack to be formed or can be conveyed further downstream, and with one a sheet guiding element adjoining the dispensing station, via which a printing material sheet to be conveyed further downstream of the dispensing station can be conveyed through the conveying system, a sheet guiding element adjoining the dispensing station can be varied in its vertical position by an actuator with at least its upstream end.

When such a delivery device is operated, the sheet guiding element adjoining the delivery station is varied in its vertical position by an actuator with at least its upstream end.

Alone or in conjunction with at least one advantageous embodiment variant of a delivery device mentioned above, a sheet guiding device for a sheet processing machine comprises at least one delivery station and a conveyor system with e.g. B. a means of conveyance, by means of which upstream processed printing material sheets can be conveyed to the dispensing station and optionally be delivered there to a stack or - in particular by means of the same conveying means - can be conveyed further over this, a stop device with one or more transversely in the region of a downstream end of the dispensing station to the direction of transport from each other spaced-apart stop means is provided, which is or can be moved, with a stop face pointing in the direction of the incoming printing material sheet, by at least one drive means optionally into an active position in which it or they are brought into a movement path of the incoming printing material sheets and in the area of a stop face as a stop is or are effective, and in an inactive position in which it is located outside the path of movement of the printing material sheet and is or are not effective. A holding means is assigned to the one or more of the movable stop means, which is forced to move when the stop means moves and in at least one inactive position of the stop means protrudes beyond the stop surface upstream and / or in the direction of the incoming printing material sheet and / or overlaps the downstream stack edge of the stack to be formed in the inactive position of the lifting means, the uppermost substrate sheet in the region of its downstream edge is held back before being lifted and carried away by the substrate sheet to be transferred. In operation, when the sling is connected from its active to its inactive position, a holding device is moved from an inactive position to a holding position in which it comes to lie over the downstream edge of the uppermost stacking sheet in order to be carried over before being lifted off and carried away Retain substrate sheet.

Accordingly, when operating a delivery device according to the invention, which comprises a conveyor system, through which a printing material sheet is conveyed downstream to a delivery station, where it is either delivered from the conveyor system to a stack to be formed there, or is further conveyed downstream by the conveyor system over the stack, while the transfer of a sheet to be conveyed, the uppermost sheet of the stack is held down from above by an optionally activatable and deactivatable holding device and / or a sheet guiding element downstream in the conveying path to the delivery station by an actuator with at least its upstream end in its vertical position varies.

In the region of a downstream end of the delivery station, a stop device is provided with one or more stop means spaced apart from one another transversely to the transport direction, which or which is or is moved with an abutment surface pointing in the direction of the incoming printing material sheet into at least one drive means in an active position, in which he or she is placed in a path of movement of the incoming printing material sheet and is or is effective as a stop in the area of a stop surface, and in an inactive position in which he or she is arranged outside the path of movement of the printing material sheet and is or is not effective. In an advantageous embodiment when holding down, when the lifting means is moved from its active to its inactive position, a holding means is moved from an inactive position to a holding position in which it projects in the upstream direction beyond the stop surface to lie above the downstream end of the uppermost stacking sheet comes, and holds it back and / or at least hinders it from being lifted off and carried away by the substrate sheet to be transferred.

Especially in the event that a printing material sheet can be picked up at the take-over location by the conveyor system and is conveyed downstream to the first delivery station comprising the first stacking space, where it can either be delivered from the conveyor system to the stack to be formed there or else by the conveyor system via the first delivery station If the delivery station downstream of the sheet guiding element is conveyed further by the conveyor system to a second delivery station comprising a second stacking space, the sheet guiding element adjoining the first delivery station in the route to the second stacking space is varied, if necessary, by the actuator with at least its upstream end in its vertical position. This takes place in particular in the phase in which a stacking table has not yet been brought into the upper desired position and / or the stack still has a very low stacking height Has.

The advantageous designs, design variants and procedures mentioned so far are of particular advantage, alone or in conjunction with one another, with regard to particularly trouble-free operation and / or transport that is as gentle as possible and / or storage of high quality. The features of the above-mentioned designs are to be combined as advantageous developments with one another and with one or more additional features of the following exemplary embodiments.

Exemplary embodiments of the invention are shown in the drawings and are described in more detail below.

This includes e.g. B. two transverse pulling devices 96, by means of which the sheets B can each be subjected to a force having at least one transverse component in opposite directions. A number of transverse pulling devices 96 corresponding to the number of braking devices 91 can be provided. The transverse pull devices 96 are preferably designed as suction wheels 96 which can be subjected to negative pressure.

The braking device 48; 49 of the delivery station I; II directly upstream in the transport path and / or is in the end region of the sheet guiding elements 47.1; 47.2; 47.3; 47.4; 47.5; 47.6; 47.7; 47.8 formed guide section integrated or provided directly after this in the conveyor line.

In a preferred embodiment, the braking stations 91 of the braking device 48 comprising the holding means 92; 49 - together or together with the downstream end of the arc guide element 47.4; 47.8 - within one significant range, e.g. B. within an adjustment range of at least 10 mm, in particular at least 50 mm, movable in and against the transport direction T in or on which the sheet guiding device 47 supporting frame G of the dispenser 03. The at least one braking station 91 is moved along the transport direction T, for example, by a drive means 63, e.g. B. a preferably designed as an electric motor 63 drive motor 63 (see z. B. schematically in Fig. 20 ).

In a particularly preferred embodiment, the braking device 48; 49 control means S106; S107 assigned by which their functional elements, for. B. one or more drives 106 and / or one or more switching means 107 relating to the holding means 92, synchronized and / or in a correlation to a machine and / or substrate phase position Φ and depending on the delivery station I to be provided for the relevant substrate sheet B; II controlled or controllable or are controlled. By a suitable control of one or more of these functional elements, the exact sheet deposit in the relevant delivery station I; II, on the one hand, and a quality-maintaining transfer of the printing material sheets B to be filed downstream is supported.

In addition to this or instead, the at least one braking station 91 of the braking device 48; 49 drive means 63 moving along the transport direction T are assigned control means S63, by means of which the position of the sheet brake 48; 49, in particular the at least one of the sheet brake 48; 49 included braking station 91, can be adapted to the format length L _{B of} the sheet B currently to be filed. By an optimal position the exact and harmless sheet deposit in the relevant delivery station I; II supports.

The movement in the transport direction T, the movement of the holding means 92 and the control means S63; S106; S107 can be in separate or all or in groups can be provided in a common control device. They can be part of a higher-level machine control system or can be provided locally and connected to one if necessary.

Depending on whether the in the area of the braking device 48; 49 incoming sheets B _n in the directly following delivery station I; II are to be delivered or to be guided over them, the drive 106 and / or the switching means 107 of one or more holding means 92 of the braking device 48; 49 in two different operating modes m1; m2 operated (see e.g. Fig. 21 ). The operating modes m1; m2 can differ in the speed profile for the holding means 92 and / or in a profile for the activation / deactivation of the holding means 92. Operation in one of the operating modes m1; m2 takes place at least for the duration of one cycle length, the cycle length being based, for example, on the machine and / or substrate phase position and e.g. B. the length of the phase between the entry of the leading end of a sheet B _i and the entry of the leading end 109 of the subsequent sheet B _{i + 1} into the braking device 48; 49 and / or the length of the phase between the exit of the trailing end of a sheet B _i and the exit of the trailing end 111 of the subsequent sheet B _{i + 1} from the braking device 48; 49 can correspond.

The decision as to whether the in the area of the braking device 48; 49 incoming sheets B _n in the directly following delivery station I; II delivered or passed over it can be taken manually or automatically by the operating personnel. In the automated decision, this can be based on a measurement or a preset sequence of copies. For example, so-called waste copies can be sent to the relevant stack 11; 12 are delivered. In the case of the formation of several so-called good-sheet stacks, the decision regarding the delivery of the assignment of the printed sheets to the individual stacks 11; 12 hit or will.

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

In the advantageous embodiment of the delivery device 03 with several, in particular two stacks 11; 12 or delivery stations I; II is each of the delivery stations I; II a braking device 48; 49 upstream. Their drive 106 can be operated or operated in such a way that the effective surface 112 of the holding means 92, which cooperates with the sheet B, has at least part of the contact time between the holding means 92 and the sheet B at a conveying speed v32, for example, which is determined by the conveying system 21 . B. a speed of the holding devices 32 or gripper carriage speed v32, lower, z. B. is operated by at least 50% lower storage speed v _from and / or is operable. In a preferred embodiment, their drive 106 can be operated dynamically in such a way that the active surface 112 of the holding means 92 cooperating with the bends B at least between the currently present conveying speed v32, determined by the conveying system 21, e.g. B. a speed of the holding devices 32 or gripper car speed v32, and a lower, z. B. lower by at least 50% storage _speed v is continuously variable.

A printing material sheet B _{n to} be deposited is placed on the input side of the braking device 48; 49 by a holding means 92 of the braking device 48; 49 recorded, in particular pneumatically sucked in, which is with or approximately with, ie with more than 95%, of Conveying speed v32, ie without or almost without relative movement between the holding device 32 of the conveyor system 21 and the holding device 92 of the braking device 48, 49, is moved in the transport direction T. After the holding device 32 has been opened, for example after the gripper has opened, the speed v92 of the holding means 92 is reduced to the lower depositing speed v _ab by changing the speed, thereby braking the sheet B and finally depositing it on the stack 11.

The reduction in speed or braking, in particular for the first braking device 48 and the second braking 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 embodiment and / or can be parameterized by means of an appropriate input .

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

To correct incorrect filing and / or to adapt to a new format length L _B , as z. B. may be necessary during a production change, the curve and / or its course can be changed by operating personnel by varying corresponding parameters defining the curve. Here, at least the height of the above-mentioned depositing speed v _ab , ie the lower final speed after lowering, can be changed by operating personnel.

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

A sheet B _{n + 1 that} is not to be deposited, ie to be transferred, is also on the input side the braking device 48; 49 by a holding means 92 of the braking device 48; 49 recorded, in particular pneumatically sucked, 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 of the braking device 48, 49, 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 has left or is just leaving. The sheet B, which is also held by the holding device 32 of the conveyor system 21, is conveyed downstream via that of the braking device 48; 49 direct submission stations I; II to another delivery station I; II or a sheet removal device 87 promoted. In order to avoid wave formation, the above-mentioned deviation is z. B. at most - 10%, preferably at most - 5%, in particular at most - 3%.

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

In the first operating mode m1, e.g. B. a filing mode m1, in which one or more sheets B from the first stack 11, z. B. waste stack 11 are to be filed, the speed of the drive 106 changes per sheet to be deposited at least once from a first speed v _a causing speed, the z. B. as the speed of the incoming sheet essentially - ie with a maximum deviation of ± 10% - corresponds to the above-mentioned conveying speed v32, to a rotational speed causing the depositing speed v _from and back again to essentially conveying speed v32. Are several consecutive sheets B _{n in} succession this first operating mode m1 repeats accordingly often so that the braking device 48, 49, that is to say the holding means 92, changes the speed v92 between the conveying speed v32 to the depositing speed v _from and back again in time with the incoming and outgoing sheets B _n .

When changing to the storage speed v _ab , the speed v92 of the holding means 92 is preferably reduced to a speed v _ab during the active contact with the conveyed sheet B, which z. B. is at most 50%, advantageously less than 20%, preferably less than 10% of the conveying speed v32. The higher speed v92 of the holding means 92, which essentially corresponds to the conveying speed v32, is above z. B. at least 4 m / s, for example in the range of 4 to 9 m / s, in particular in the range of 5 to 8 m / s. In contrast, the storage speed v _from z. B. at most 2 m / s, for example in the range from 0.5 to 2 m / s, in particular in the range from 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 substantially 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 leading edge 109 of the sheet B _{n + 1} to be deposited; B _P only less than half a sheet length from the flight s2 to the downstream stack trailing edge or the leading edge 111 of the sheet to be deposited B _{n + 1} ; B _{P is} only less than half an arc length from the flight s1 to the upstream stack front edge.

In the second operating mode m2, e.g. B. a guidance mode m2, in which one or more sheets B over the first stack 11, z. B. waste stack 11, or the delivery stations I are to be moved, the drive 106 is at least over the entire phase of contact between the braking device 48, 49, ie the holding means 92, and the sheet B to be fed over the stack 11 or the delivery station I. operated at a speed which is essentially a Conveying speed v32 causes 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 fundamentally independent of the presence or the special execution of a first operating mode, but is particularly advantageous in connection with an execution of a first operating mode described here.

In a preferred embodiment of the braking device 48; 49, activating and deactivating holding means 92 are provided in clocked fashion via corresponding switching means 107. For clocking, the switching means 107 is in signal connection with control means S107, for example, which is designed and set up to synchronize activation and deactivation of the holding means 92 and / or to bring about a correlation to a machine and / or substrate phase position Φ. In the case of two operating modes m1; m2, these differ not only in the phase-related speed profile, but also in the switching profile for the wiring, i.e. H. Activation and deactivation of the holding device (s) 92.

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

In the second operating mode m2, the activation of the holding means 92 is maintained over at least the entire phase of contact between the braking device 48, 49, ie the holding means 92, and the sheet B to be passed over the stack 11 or the delivery station I. The suction or the negative pressure p- is preferably maintained over the entire cycle. In the embodiment as suction elements 92, suction remains switched on in at least this contact phase, ie the vacuum p ^- maintained on the suction element 92. The suction or the vacuum p ^- preferably remains over the entire cycle from the entry of the sheet B _n to be transferred into the area of the braking device 48; 49, in particular in the effective area of the holding means 92, until the next following 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} ; To transfer B _{n + 2 in} succession, the suction or the vacuum p ^{- can} remain switched on for the duration of the relevant cycles.

Sucking over the entire cycle, in particular over the cycles of a plurality of sheets to be transferred, ensures that the sheet in the second operating mode m2, ie the guide mode m2, detects the sheet B _{n + 1} to be transferred and essentially without relative movement over the to be transferred stacks 11, 12. This prevents or at least reduces, the sheet B _{n + 1} to be transferred into the storage shaft of the stack 11 to be transferred, which allows transfer without loss of quality. This is particularly relevant for productions with high conveying speeds.

A suction air that is permanently switched on in the second operating mode m2 favors the earliest possible starting and holding of the rear edge of the sheet B.

For the two operating modes m1; m2 are, for example, in the control means S48; S49 maintains two differing regulations for the generation of setpoints for the speed v92 of the holding means 92. The regulations include, for example, a dependency on the conveying speed v32 and can also depend on other influencing variables and can be parameterized by operating personnel.

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

When operating the dispenser 03, for example, several, e.g. B. n (n ∈ N), sheet B _i (i = 1 ... n) - in particular using the sheet brake 48 operated in the first operating mode m1 - stacked in the area of the first delivery station I as waste on a first stack 11. At least one sheet _{Bn + 1} adjoining the n sheets is z. B. as a test sheet or as a good sheet - in particular using the sheet brake 48 operated in the second operating mode m2 - fed over the first delivery station I or the first stack 11 and downstream of a further delivery station II or a sheet removal device 87. After, for example, a predefined number of set-up sheets have been fed as waste to the first delivery station I and / or, for example, a sample sheet has been found to be good, the system is automatically or manually switched to a production operation in which the sheets B _{i are} regularly deposited in the good sheet stack 12. During production operation, however, it can happen for various reasons that one or more sheets B _P - in particular using the sheet brake 48 operated in the first operating mode m1 - are to be fed to the first or waste stack 11. These can be, for example, replacement sheets or incorrect or damaged sheets when changing stacks. Such a sheet B _{P to} be discharged during the production run can be triggered manually or by a sensor system or will.

To control the at least one drive 106 driving the holding means 92 and / or the at least one switching means 107 activating the holding means 92, the drive 106 and / or the switching means 107 is in signal connection with control means S106; S107, which in turn, for example, in signal connection with a signal generator, for. B. a sensor or a drive master, from which it receives the machine and / or substrate phase position and / or represents information l (Φ). The control means S106; S107 comprise a control circuit and / or an algorithm which is set up to adapt to the operating modes m1; m2 to control the drive 106 and / or switching means 107. That in relation to the design of the braking device 48; 49 is also to be applied to the fact that so-called gut sheet B _{n + 1} in the first or second delivery station I; II and so-called waste sheet B _n ; B _P in the other delivery stations II; I are to be or are to be filed. Here, under waste sheet B _n ; B _P Setup sheet, defective discharge sheet or sheet after manual decision by the staff. For example, the waste sheets are or are deposited on a stack 11 in the area of the first delivery station I and good sheets in the area of the second delivery station II. The above-mentioned procedure and / or control of the braking device 41; 42 can, however, also be provided or used in reverse assignment of waste and good sheets, as well as in connection with the formation of several printing material stacks, each of which is different from waste.

The above-mentioned setting of the position of the braking device 48; 49 in the direction of transport T, in particular the position X ₉₁ considered in the direction of transport T of the braking devices 91 which interact with the sheet B via the holding means 92 and which, for example, represents the size to be set or, for short, the setting size X ₉₁ via a manipulated variable representing the desired height or a change to be made, which are fed or can be fed to the relevant control means S63 and which is reflected, for example, in a corresponding actuation of the drive means 63.

The position of the braking device 48; 49, or the manipulated variable relating to the holding means 92, can be specified directly as a command by operating personnel, in particular by signals σ _{FL of} one or more operable by operating personnel, in signal connection with the drive means 63 concerned of the borrow brake 48; 49 controlling control means S63 standing actuating means 196; 197; 198; 199, hereinafter also as switching elements 196; 197; 198; 199 or z. B. as button 196; 197; 198; 199 can be given (see e.g. Fig. 39 ). The signals σ _FL generated by actuation can directly represent a desired position or a change interval with direction. The at least one switching element 196; 197; 198; 199 can from one of the relevant delivery station I; II laterally assigned and set up user interface 66; 67 may be included.

To influence the position manually, for the concerned brake 48; 49 each a switching element 196; 198 are provided, by the actuation of the braking device 48; 49 or the or the holding means 92 is or can be moved to a further downstream position, d. H. for a smaller format length compared to the current format, and one switching element 197; 199, by its actuation the braking device 48; 49 or the or the holding means 92 is or can be moved to a further upstream position, d. H. can be changed for a smaller format length compared to the current format. This allows, for example, both finer corrections to be made and, if necessary, an adaptation to a new format.

An above-mentioned setting of the placement speed v _ab (as the size to be set or

Setting variable v _from the drive or drive means 106) to a desired height takes place, for example, via a manipulated variable representing the desired height or a directional change interval, which are fed or can be fed to the relevant control means S106. These are reflected, for example, in a change in the parameters on which the profile is based and ultimately in a corresponding activation of the drive means 106. This setting can also preferably be carried out by operating personnel (see below).

Instead of or preferably in addition to this manual influence, the desired position of the braking device 48; 49 and / or the holding means 92 and / or the manipulated variable relating to the height of the depositing speed v _ab also by specifying setpoints W _B , z. B. a parameter set W _B determined and / or held for a format to be output, effected and / or effectable. The latter can be communicated or transmitted by a product planning and / or presetting system.

In a preferred embodiment of the delivery device 03, which in the transport path of sheet B conveyed by a conveyor system 21 has a last in the transport direction T, for. B. second stack delivery II and at least one of the last stack delivery II upstream in the transport path, z. B. comprises first stack delivery I, the upstream stack delivery I in the transport path is preceded by a braking device 48 and / or a sheet guide element 47.4 which is variable in terms of effective length, the braking device 48 itself or at least one active surface 112 of the braking device 48 and which comes into active contact with the printing material sheet B. / or a downstream end of the sheet guiding element 47.4 of the upstream stack delivery I, for changing the effective length, for depositing sheets B of a first format length LB into a first position P ₁ (48) when viewed in the transport direction T; P ₁ (47.4) and for storing sheets B 'at least one second, compared to the first format length L _B smaller format length L _B' in a further downstream viewed in the transport direction T. second position P ₂ (48); P ₂ (47.4); P _S (48); P _S (47.4) is shiftable.

In a first mode of operation, all delivery stations I; II activated, d. H. fundamentally ready sheet B to be stored. The Biogen B can in the respective delivery stations I; II depending on the above Control commands to the relevant stack 11; 12; 168; 169 delivered or transferred via this, the respective braking device z. B. is operated according to the destination in the first or second operating mode m1, m2.

B. second stack delivery II and at least one of the last stack delivery II upstream in the transport path, front, z. B. comprises first stack delivery I, with at least the upstream stack delivery I in the transport path being associated with a braking device 48 and / or with a sheet guide element 47.4 which is variable in effect length, so in a first operating mode the braking device 48 itself or at least one which comes into active contact with the printing material sheet B Effective surface 112 of the braking device 48 of the front stack delivery I and / or the sheet guide element 47.4 of the front stack delivery I, which is variable in terms of effective length, or at least its downstream end in at least one first mode of operation of the delivery device 03 as a function of a current, ie to be stored, format length L _B ; L _{B '} along the transport direction T in different positions P ₁ (48); P ₁ (47.4); P ₂ (48); P ₂ (47.4) positioned.

In a second embodiment of the at least one first and a second delivery station I; II comprehensive delivery device 03 (see e.g. Fig. 22 ) is or is operated, for example, during a production or production phase in such a way that a - in particular from a first delivery station I different, eg. B. downstream last - delivery station II is active, ie is basically ready for depositing sheet B, while another - In particular, this active delivery station II upstream or front delivery station I is deactivated, ie storage in this delivery station I is neither possible nor provided in this operating state. The basic readiness of the first-mentioned delivery station II can include both continuous storage and operationally optional storage or transfer in the above sense. In this mode of operation, the delivery device 03 is therefore not equipped with all of the delivery stations I; II, but with a reduced number of delivery stations I; II operated. The deactivated delivery station I; II is operationally transferred through all incoming sheets B in this mode of operation, without being able to be deposited there by an automatism or a manual setting command.

First, for example, for such a production or production phase with a reduced number of stacks, the delivery station I, z. B. the first delivery station I deactivated. Deactivating the relevant stack delivery I can during the machine configuration for the pending order, i. H. the definition and / or presetting of the units involved for the pending order. This can be done, for example, directly at a control center or on an actuating means connected to this, or else automatically via imported production data.

To displace the braking device 48 or at least its active surface 112 or the sheet guide element 47.4 which can change the effective length or its downstream end of the deactivatable stack delivery I, an above-mentioned drive means 63 is provided and preferably a control means S63 which is in signal connection therewith and which controls the braking device 48 or its Effective surface 112 and / or at least the downstream end of the sheet guide element 47.4 of the upstream stack delivery I, which is variable in effect length, depending on the operating mode of the delivery device 03, optionally in a first operating mode depending on a current format length L _B ; L _{B '} positioned and for operation in a second mode of operation at a fixed defined support position P ₂ (48); P ₂ (47.4); Ps (48); P _S (47.4), which is preferably located at a location downstream of that position P ₁ (48); P ₁ (47.4) is located, which would have to be provided in the first operating mode for the format length L _B currently to be displayed in the delivery device 03.

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

This location is preferably downstream of position P ₁ (48); P ₁ (47.4), which would be provided for the format length L _{B of} the sheet B currently to be displayed in the delivery device 03 in the first operating mode.

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

The support position P ₂ (48); P ₂ (47.4); P _S (48); P _S (47.4) can position P ₂ (48); P ₂ (47.4) correspond to the position to be set for a smallest format length L _B of sheets B to be filed in the first operating mode. In other words, the braking device 48 itself or at least one active surface 112 of the braking device 48 which comes into active contact with the printing material sheet B and / or a downstream end of the sheet guide element 47.4 which is variable in terms of the effective length is reduced to the smallest format to be designed, e.g. B. Minimal format set. In principle, the movement path can extend beyond this setting for the minimal format downstream, with the support position P ₂ (48); P ₂ (47.4); P _S (48); P _S (47.4) can then be given by the downstream limitation of the possible movement path.

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

In the case of movable stop means 83 (see, for example, below) at the upstream end of the conveyor line adjoining the delivery station I in question, they are in the second operating mode or are moved out of the path of movement of the sheets B for the second operating mode.

In an alternative embodiment for operation in the above-mentioned second mode of operation with at least one deactivated delivery station I to be transferred - instead of or if necessary in addition to the above-mentioned positioning of the braking device 48 or its holding means 92 and / or the sheet guiding element 47.4 - a shortening of a free length of the sheet guiding gap can be provided or provided by other mechanical support means. This can be, for example, a sheet guiding element, which, for. B. by the correspondingly raised support 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 delivery station I, the carrying device 36; 37 by vertical positioning in a transport path near, z. B. highest possible location. In addition to this, a named sheet guiding means can be put on or used before, during or after reaching this position.

As already indicated, the run-up section 78 has a run-up slope in the region of its upstream end, preferably with a rounded edge 84, in particular upper edge 84. For this purpose, the essentially flat guide surface 79 of the start-up section 78 facing the conveyor system 21 sits in a downwardly bent, e.g. B. rounded contact surface 81 continues. Under the essentially flat guide surface 79, in addition to actually flat surfaces, slightly curved surfaces with a radius of curvature of z. B. be understood continuously at least 1,000 mm, in particular at least 3,000 mm. The rounding of the edge 84 is z. B. in such a way that the edge 84 is rounded in such a way that a course of the upper side viewed in a vertical section running in the transport direction extends between a first point lying in the region of the still flat or slightly inclined guide surface 79 up to a second point , at which an inclination of the tangent to that at the first point is 45 °, has at least a radius of 50 mm and / or that a course of the edge 84 between the end of the flat or at least substantially flat guide surface 79 and one perpendicular to the course 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 does not have to be constant in the section under consideration, but can vary. A leg that possibly includes the rounded contact surface 81 mentioned can in principle be continuous, partially interrupted or multi-part in the transverse direction, ie in the direction of the width of the dispensing device (see, for example, Fig. 8 ). In the following, the expression of the "flat guide surface" is intended to include the above-mentioned case of a slightly curved surface.

As the "edge" 84 of the run-up section 78 in the above sense, the upper corner region of the run-up section 78 should be understood here, regardless of whether it is z. B. by the rounded corner of a solid component or z. B. is formed by a sheet bent downwards.

Preferably, stop means 81 of a stop device are provided in or before the vertical alignment of the contact surface 79 and below the height given by the guide surface 79, which limit the movement in the transport direction T for the sheets B to be deposited in the first delivery station I. The downstream stack edge of the stack 11 to be formed is formed on these stop means 82. In addition to this, movable stop means 83 can be provided, which are driven by a drive device 64 with at least one drive means 99 in a first, e.g. B. active operating state protrude beyond the height given by the guide surface 79 and in a second, for. B. inactive operating state are arranged below this height. In a less complex embodiment, several of the stop means 83 can be moved or moved together via, for example, a connection or shaft. The run-on section 78 can have air passage openings 68 in the region of its guide surface 79 and / or in the region of its run-up surface 81 and / or in the region of its rounded edge 84; 69, in particular blown air openings 69 or blown air-operated air passage openings 69.

In a first preferred embodiment of the start-up section 78 it comprises in In the region of the rounded edge 84, ie in a curved surface section 84 adjoining the flat guide surface 79, a blowing device with one or preferably a plurality of blowing air openings 97. The blowing air openings 97 can be formed by round or preferably slit-shaped recesses 97 in a material section forming the rounded edge 84 84, in particular sheet metal section 84, and be supplied with blown air from the inside of the run-on section 78, ie from the side of the material section 84 facing away from the printing material transport. The blown air supply can be formed by an air box adjoining the material section 84 on the inside.

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

In a particularly advantageous refinement, the preferably tubular blown air line 98 can be mounted so as to be pivotable about an axis running in the transverse direction. In this way, particularly in the case of blower air openings 97 which are larger than the outlet openings in the above manner, the position of the blown air outlet along the arc movement direction can be adjusted at least slightly.

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

The sheet B, which is guided only at the front edge by the conveyor system 21 or the holding device 32, in particular the holding elements 56, lowers into the shaft of the delivery station I passed over; II until it is in equilibrium with the natural air cushion that forms on the underside. The continuation of the arch guidance on a predominantly horizontal guideway can be at the end of the delivery station I; II - especially in certain operating situations with, for example, a low stack level .- lead to a harmful level jump. In this case, the natural air cushion is unable to bend the arch B like a wing over this step onto the following arch guide element 47.5; 78, in particular thrust plate 78 to lift. Above all, at higher speeds, there can be an impact with damaging contact on the underside of the bow B.

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

At least the upstream end of the run-on section 78 is at the height of the variable stacking level, i. H. the height of the top sheet B in the stack 11; 12, adjustable. This end is preferably automatically adjustable in height to the variable stacking level, in particular via control means. For this purpose, the drive means 283 comprised by the actuator, in particular its control device or drive controller, is in signal connection to a control means which sets the vertical position of at least the end of the sheet guide element 78 as a function of and / or correlates with the stack level.

The setting or the variation takes place at least within an operationally provided setting range, which extends from an upper layer L _O , in which, in the production run, the stack 11; 12 a minimum height without further height variation of the starting section 78 until the target stack height is reached, down to a lower layer Lu, in which, for. B. is stored in the production plant at the start of stack formation (see, e.g. Fig. 9a ) and c). The latter is started up, for example, when the time of moving the stacking table 36; 37 is to be used at least in part until the working height assumed above for the production run has been reached and / or if the working height, ie the level of the uppermost sheet position ideally to be assumed in the production production mentioned above, is to be used due to a limited adjustment path for the stacking table 36; 37 cannot be reached with small stack heights. The between these two layers L _O ; L _U L _Z located layers (e.g. see. B. Fig. 9b ) can in principle be or will be approached in a stationary manner in other special operating situations, but are or are regularly on the way between the other two positions L _O ; L _U just drive through dynamically. The operationally intended setting range between the upper and lower layer L _O ; L _U is, for example, at least 50 mm, preferably more than 100 mm. Basically, positions that go beyond these two limits (position L _O and position Lu) can be approached on one or both sides, but these can be approached, for example, for set-up or maintenance work or other non-operational actions.

Due to the variability mentioned, the start-up section 78 is designed and / or supported in such a way that, even for levels that are reduced compared to the maximum or the stack level assumed, the current stack level with the higher, preferably horizontal, sheet guiding level for this case, i. H. the level specified by the course of the conveyor system. Here, the "stack level" is to be understood as the vertical position of the upper end of the stack.

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

The sheet guide element 47.5; 78 or the sheet guiding element 47.5; 78 in the vertical position varying drive means 283 can, for example, not shown here Controls can be set manually. Instead or advantageously in addition to this, the sheet guiding element 47.5; 78 or the sheet guiding element 47.5; 78 drive means 283 which vary in the vertical position can preferably be set automatically via control means, preferably — at least in an operationally provided setting area or a partial area — correlates to the vertical position of the top of the stack in the upstream stacking space 44; 46 adjustable. In operation, the vertical position of at least the upstream end of the run-up section 78 is correlated to the vertical position of the top of the stack in the upstream stacking space 44; 46 varies. The vertical position of the upstream end or the drive means 283 can be controlled, for example, as a function of information representing the position of the top of the stack. Instead or in addition to this, the vertical position of the upstream end or the drive means 283 in connection with and / or correlated to control the vertical position of the stacking table 36; 37 be controllable and / or controlled.

A sensor system set up for this purpose can be provided, for example, to provide information representing the position of the top of the stack. Their output signals or results prepared therefrom are, for. B. supplied to the control means or these can be supplied. For example, a distance sensor can be provided above the stack 11, 12 or a sensor system recognizing the upper stack edge can be provided in the upstream end face of the run-up section 78.

The sheet guiding element 78 is preferably arranged and / or stored in the delivery device 03 such that when the vertical position of the upstream end of the sheet guiding element 78 lies within the operating range provided for operational purposes, the respective upstream stacking space 44; 46 end face of the sheet guiding element 78 facing perpendicularly against the transport direction T come to lie on a substantially vertical line. The "essentially vertical line" should also be a straight line vertical line includes, like a line with a maximum deviation of 5 ° to the vertical, straight or constant or varying curvature, the minimum radius of curvature of which corresponds to twice the length of the sheet guiding element 78 extending in the transport direction T. This course of the lines has in common that the end face areas closest to the stacking space in the respective vertical position opposite to the transport direction T and thus also the position of the first contact by an accruing arc B does not change significantly despite the vertical variation in the horizontal direction.

This essentially vertical positioning of the upstream end takes place via an actuator, which is located directly at or at least close to the end to be moved. H. for example, in a first tenth of the sheet guide element length, viewed in the transport direction (T) - engages on the starting section 78 and shifts the starting section 78 at the point of application along a vertical linear movement.

In an advantageous embodiment, the sheet guide 78 or the z. B. also designated as a stop plate 78 in an advantageous embodiment executed and / or stored so that the vertical level of the sheet B at the downstream end supporting surface 79 remains with varying vertical position of the upstream end. However, this is said to be negligible deviations in the range of a few millimeters, e.g. B. of up to 5 mm. By maintaining the level, a transition to a subsequent section or sheet guiding element 47.5 can be kept virtually steplessly regardless of the vertical position of the upstream end in the above sense.

In the event that the above-mentioned variation of the height of the upstream end along the above-mentioned, essentially vertical line and a maintenance of the level at the downstream end is provided, a guide device with a stop means fixed to the frame is provided 288 is provided, which interacts with a stop means 289 which is fixed to the start section, in particular in a region of the start section 78 closer to the downstream end than closer to the upstream end, for defined position taking of the downstream end of the start section 78.

The sling means 288; 289 are designed in such a way that with vertical variation of the upstream end along the essentially vertical line and the associated horizontal movement of the downstream end, the guide surface 79 effective in the transition region to the downstream sheet guiding element 47.5 maintains the level in the above-mentioned manner. It includes e.g. B. at least one of the stop means 288; 289 a correspondingly shaped stop curve, on which the corresponding stop means 289; 288 supports. For example, the frame-fixed stop means 288 comprises such a curve, on which the z. B. trained as a roller 289 run section fixed stop means 289 runs along. The stop means 289 fixed to the run-on section can be supported from below by the stop means 288 fixed to the frame. a. - gravity ensures a safe contact. Conversely, the stop means 289 fixed to the starting section can be pressed from below against the corresponding stop means 288 fixed to the frame. In this case, this can be effected either statically via a spring element acting on the starting section 78 or else via a drive means, by means of which, for. B. the corresponding sling means 288; 289 can optionally be brought into contact with one another and out of contact. In the embodiment with an embodiment set out below, a starting section 78 which can be swiveled with the downstream end in the event of a fault, the starting section 78 which engages on the starting section 78 and is intended for the contact between the corresponding stop means 288; 289 providing drive means can be formed by the drive means 104 causing the pivoting.

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

The start section 78, also called the start plate 78, can be in several parts, e.g. B. can be formed from several adjacent baffles. The guiding contour of the run-on section 78 can be composed of flat and curved sections. In an advantageous embodiment, the run-on section 78 comprises in the area of the guide surface 79 and / or in the area of the bent edge 84 or the like. Air passage openings, in particular blown air openings 69; 97 has. For this purpose, the start-up section 78 in the manner described above, for. B. supplied with blown air.

In addition to the above Blowing device and / or for the vertically variable design of the upstream start section end or on its own can, in a further advantageous embodiment or variant of a start section 78, a. Stop device can be designed such that a plurality of stop means 83; 86 individually or at least in several groups by a corresponding number of drive devices 64 or drive means 99 between the active and the inactive position, z. B. pivotable or z. B. are translationally movable.

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

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

In principle, the sling means 83; 86 via the switching means 101 or valves 101 assigned to the drive means 99, for example in the manner of a valve terminal, can be combined centrally at one point. In a preferred embodiment, however, the switching means 101, in particular valves 101, are arranged decentrally and / or at least in groups or preferably all spatially spaced from one another, in particular in each case close to the associated pneumatic cylinder 99. The switching means 101 or valves 101 are, for example, each arranged closer to the associated pneumatic cylinder 99 than to one or the other pneumatic cylinders 99. At least, however, they are arranged closer to the assigned pneumatic cylinder 99 than half the distance between the two most widely spaced pneumatic cylinders 99.

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

The control means S83 (S86) can be part of a higher-level machine control or can be provided locally and possibly connected to one.

The switching of the slings 83; 86 takes place e.g. B. depending on whether a substrate sheet B in the upstream delivery station I; II filed, or is to be conveyed to another delivery station II or a sample sheet.

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

In an advantageous development of the run-on section 78, blown 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 which continues the guide surface 79.

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

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

Furthermore, in an embodiment variant (not shown here) of the stop device comprising the pivotable stop means 83, mechanical holding devices can be integrated in the structural unit of the start-up section 78, which hold down substrate sheets B that have already been placed in the upstream delivery station I, while subsequent substrate sheets B lead to a further delivery station II or one Tapping point to be transferred. Such a holding device is, for. B. in the event of an intended renewed depositing of a further sheet B on the stack 11, 12 of the upstream delivery station I, preferably at least for the required period of time from the movement path, in particular at least the fall path of the sheet B. Such a holding device can prevent a sheet B which has already been deposited from being carried away, but at least can make it difficult or inhibited.

When changing from the first to a subsequent stack 11; 12, e.g. B. the waste stack 11 on the good sheet stack 12, the necessary for storage on the first stack 11, the sheet B catching sling means 83 are brought from the path of movement of the sheet B, for the transfer of printing material sheet B, z. B. Gutbogen to have a free passage space available. However, the problem may arise that - e.g. B. in spite of a possibly provided blowing device - the last just deposited sheet B, which possibly form a "buoyant" ream still provided with air pockets and by the fluidic forces of the z. B. designed as a gripper 32 holding devices 32, which promote the sheet B at full speed, a Trift occurs that can lead to entrainment of the ream or individual sheet B at the end.

In order to counteract this, one or more stops 83 - as in the first embodiment set out above - are designed and movably mounted so that they are in the active state, ie. H. in an active position, in the path of movement of the printing material sheet B and this with a side facing the leading sheet ends, for. B. a stop surface, are effective as a front stop, and in the inactive state, d. H. in an inactive position, the printing material sheet B arriving from the movement path is moved out, that is to say are arranged outside the movement path, and are without a stop effect for the incoming printing material sheet B. In addition to this, one or more of the movable stop means 83 is assigned a holding means 299, which is forcibly moved with the movement of the stop means 83 and, in at least one inactive position of the stop means 83, protrudes beyond the stop surface in the direction of the incoming printing material sheet B, which in the inactive position of the stop means 83 holds back the uppermost substrate sheet B in the region of its downstream edge before it is lifted off and carried away by the substrate sheet B to be transferred. Preferably, the holding means 299 comes in the active position of the assigned stop means 83 downstream and / or above the movement path of the printing material sheet B to be delivered to the stack 11 and in the inactive position of the assigned stop means 83 below the movement path of the printing material sheet B and further to be conveyed over the stack 11 to lie above the uppermost printing material sheet B of the stack 11.

The holding means 299 assigned to the sling means 83 thus holds the uppermost layer of the stack 11 down against lifting and / or entrainment by the substrate sheet B to be subsequently transferred when the sling means 83 is inactive . A maximum slight distance can e.g. B. correspond to a length with which, viewed in plan view, the holding means 299 in the holding position and the stack floor plan overlap at the downstream end of the stack 11 in the transport direction T.

In a preferred embodiment, the assignment of the holding means 299 can be realized in such a way that an upper part of the stop means 83 in the inactive position comprises the holding means 299 reaching upstream over the stack edge. Alternatively, a holding means 299 could also be rigid or connected to the stop means 83 via a mechanical coupling, so that the required movement of the holding means 299 is forced by movement of the stop means 83 and / or vice versa, the movement of the stop means in question with movement of the holding means 299 83.

The stop means 83 is preferably designed as the stop 83 serving in the active position for the approaching printing material sheet B as the front stop, which in particular in the region of its upper end in the inactive position - for holding down the uppermost stack position as the holding means 299, rising upwards over the stop surface 302 and rising with it the stack plan at its downstream end at least as a holding means 299 overlapping projection 299 in the manner of a holding finger bent upstream. The projection 299 or holding finger used to hold it down can also be referred to as a cover mark 299.

In the embodiment of the stop means 83, in which they also include the holding means 299, the sheets of printing material B to be deposited, e.g. B. waste sheet against these movable stop means 83 or 83 stops. If the substrate sheet B, e.g. B. good sheet over the stack 11, z. B. to a subsequent delivery station II, these stop means 83 are moved from their in the trajectory "catcher position" into a retreat position lying outside the trajectory, the holding means 299 or cover marks 299 comprised by the stops 83 preventing the top stack from being carried and / or hold down against slipping.

In principle, the movement of the sling means 83 can be carried out by pivoting. B. contrary to the above-described embodiment, the pivoting to take the retreat position does not take place downstream, but in the upstream direction. In this case, the uppermost stacking sheet can be held down, for example, by the stop means 83 pivoted upstream. The movement can also take place on any other movement path, provided that the stop means 83 and the holding means 299 assigned to it assume the positions defined above.

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

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

As already stated above, for moving all, a group or preferably the individual stop means 83; 86, the drive means 99 can in principle be of any design, but is preferably a pressure fluid that can be acted upon Cylinder-piston system 99, in particular as a pneumatic cylinder 99.

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

The motion-causing drive means 99, e.g. B. the pneumatic cylinder 99 can basically attack directly on the output side on the holding means 299 comprising stop means 83. Preferably, however, the drive means 83 is driven by a gear, e.g. B. via a the travel of the drive means 99 enlarging gear. In an advantageous embodiment, this transmission is in the form of a coupling gear, in particular a fast-shifting gear. For example, this is designed as a straight guide gear on the basis of an isosceles crank. For this purpose, the stop means 83 to be moved acts in at least one point with a guide 297, z. B. linear guide 297 together, so that the stop means 83 is linearly guided or moved at least at the level of this point. In principle, a point of the stop means 83 that is spaced apart in the direction of movement could be guided linearly by the same or a further linear guide 297. A gear member 292, e.g. B. a coupling 292. Spaced from this pivot axis 301, a further gear member 296, for example, engages over a further second pivot axis 298 running parallel to the first pivot axis 301. B. a crank 296 on the coupling 292. The crank 296 is on a frame 303 about a to the first two pivot axes 301; 298 parallel pivot axis 304 pivotally mounted. In a preferred embodiment, that between the first two pivot axes 298; 301 effective length of the coupling 292 of the between the second and third pivot axes 298; 304 effective length of crank 296.

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

In a preferred embodiment here, a multiple coupling or a coupling with the linear guide 297, which coupling extends significantly in the direction of movement, can be dispensed with by forcing the coupling 292 onto a defined movement curve when moving by the crank 296 in a coupling-fixed engagement point spaced apart from the second pivot axis 298. The coupling-fixed second point of attack can basically be in the first two pivot axes 298; 301 connecting connection section, but is preferably located in a connection section 307 extending beyond the second pivot point 298 in a section 307 which is different and in particular opposite to the effective direction of the connection section. This section 307 can be part of a coupling 292 which is extended beyond the point of engagement of the second pivot axis 298 or it can be designed as a lever arm rigidly connected to the coupling 292 and is referred to in the following independently of this as the section 307 extending the coupling 292.

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

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

The gear attacking on the gear 86 can - such. B. in Fig. 14 and Fig. 15 shown - be designed and arranged such that the pivot axes 298; 301; 304; 306; 308 extend perpendicular to the transport direction T. Alternatively, however, it can also be designed and arranged rotated through 90 °, so that the pivot axes 298; 301; 304; 306; 308 run in the transport direction T.

Although the design of delivery device 03 and / or sheet guiding device with a sheet guiding element 78 adjoining the delivery station with an end that can be varied in its vertical position, as well as the design of delivery device 03 and / or sheet guiding device with the stop device (s) 299 comprising the holding means also on its own If they are to be used advantageously, their combined design offers particular advantages with regard to the safe and gentle transport of the printing material sheets B (see, for example 11, 12 and 13 such as Fig. 14 ).

For example, shows Fig. 11 the upstream end of the sheet guide element 78 in the upper position L _O , while the stop means 83 comprising the holding means 299 are in Fig. 11a ) in the active position L _A and in Fig. 11b ) is in the holding position L _H. The representations in 12 and 13 show the same facts, however in Fig. 12 with in the lower layer Lu and in Fig. 13 with sheet guide element end 47.6 located in an intermediate layer Lz; 78.

In an advantageous further development, the starting section 78 can be moved in this way in or on a spatially fixed frame G or frame part G of the dispensing device - basically regardless of the above-mentioned type and design of the stop movement or vertical variability at the upstream end and / or of the specific drive configuration of the stop means 83 03 be stored so that it can be removed from the position assumed in the operating position and thus can be removed from the sheet transport path present in the operating position, preferably downwards. Although it could also be mounted so as to be linearly movable, it is preferably mounted so that it can be pivoted downward about a pivot axis A78 running transversely to the transport direction out of the operating position (see, for example, 24 a) and b) . The pivoting takes place z. B. by means of a drive means 104, which is preferably designed as a pressure fluid-actuated cylinder-piston system 104. Preferably, the drive means 104 moving the starting section 78 can be connected to and controlled by control means S78 with regard to its activation via a signal connection. B. via a signal connection 107 with a - in particular optical - sensor 108, z. B. is connected to a photo sensor 109. Irregularities in the sheet travel, in particular a crumpling and possibly getting stuck in an incoming printing material sheet B, can be identified by this, for example via a corresponding signal evaluation. The control means S78 can be set up and / or designed to automatically generate a signal, which causes a malfunction in the printing material run, in particular a crunch, to move away, in particular to pivot away, of the start-up section 78 and to generate a signal To supply drive means 104.

It is preferably moved out or swiveled out so that the downstream one The end of the sheet guiding element 78, which is preferably designed as a run-up section 78, is or is moved further from the transport path present in the undisturbed operation, in particular further downward, than the upstream end.

Above-mentioned stop means 83 are preferably structurally integrated in the run-up section 78 or movably mounted sheet guiding element 78. In the latter case, these z. B. moves with the sheet guide 78 with this.

Preferred in the area of the first and / or second delivery station I; II, at least on one side, preferably on both sides of the movement path of the sheet B, a device 103, or side stop device 103, which serves to stop the sheet B laterally, is provided, which the device in the relevant delivery station I; II sheet B to be put down for exact alignment of the stacking edge as lateral path limitation (see e.g. in Fig. 5 ). Such a side stop device 103 preferably comprises movable stop means 201 (see below), which enable fine adjustment and / or adaptation to varying format widths of the sheets B, laterally, ie in the direction of the stack width running transversely to the transport direction T.

The sheet guide and / or controlled placement on the stack 11; 12 is - as already indicated above - in a preferred embodiment by means of a blast air operated or operable device 51; 52 supports. For an embodiment with only one delivery station I for this delivery station I, for an embodiment of a delivery device 03 with two or more delivery station I; II for one of these delivery stations I; II or for several or all of this delivery station I; II be of particular advantage and application.

Es sind beispielsweise mindestens fünf (o ≥ 5) oder bevorzugt mehr als 7 (o > 7) hier z. B. zehn (o = 10) Blasvorrichtungen 113q vorgesehen.The above the transport path above the delivery station I; II arranged blowing device 51; 52 in the transport direction T includes a plurality, e.g. B. Number o (with o ∈

, o> 1) of blowing devices extending in the transverse direction 113q (q ∈ {2,3, ... o}), which are preferably designed as so-called blowpipes 113q, in particular transverse blowpipes 113q, and in one embodiment variant can have sections or one or more chambers. For example, there are at least five (o ≥ 5) or preferably more than 7 (o> 7) here z. B. ten (o = 10) blowing devices 113q provided.

The transversely extending blowing devices 113q can each be replaced by a transversely extending z. B. at least half the maximum substrate width continuous - flat jet nozzle can be formed.

Es sind je Blasvorrichtung 113q beispielsweise mindestens 8 (q ≥ 8) oder bevorzugt mehr als 12 (q > 12) hier z. B. sechzehn (q = 16) Blasöffnungen 113q vorgesehen. Die Gruppe 113q von Blasluftöffnungen 114r wird bevorzugt durch ein die Blasluftöffnungen 114r aufweisendes Blasrohr 113q gebildet.The blowing devices 113q extending in the transverse direction are preferably each formed by a group 113q of blowing elements 114r provided next to one another in the transverse direction, that is to say transversely to the transport direction T. The group 113q includes z. B. each have a number p (with p ∈

, p> 1), blown air openings 114r, in particular blown air nozzles 114r (r ∈ {2,3, ... p}) and extends z. B. over at least the two middle quarters of the maximum substrate width. There are at least 8 (q 8 8) or preferably more than 12 (q> 12) here z. B. sixteen (q = 16) blow openings 113q are provided. The group 113q of blown air openings 114r is preferably formed by a blown tube 113q having the blown air openings 114r.

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

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

Preferably, at least one switching means 116 is provided for each blowing device 113q, by means of which the respective group 113q or a subgroup thereof can be activated, i. H. is pressurized with blowing air. In a particularly responsive version, there are several, e.g. B. two subgroups of blown air openings 114r are provided which can be switched via a number of switching means 116 corresponding to the number of subgroups, i. H. can be activated and deactivated. In a particularly responsive and preferred embodiment in this regard, for several or all of the blowing devices 113q, the left and right half of the blowing air openings 114r of the blowing device 113q, in particular the z. B. two-chamber blow pipe 113q, a switchable from the other switching means 116 switchable switching means 116 is provided. The switching means 116 are designed as electronically switchable slide 116 or rotary slide valve 116 or preferably as electronically switchable switch valve 116, or valve 116 for short. Compressed air is present on the input side thereof, which can be switched through to the output side via corresponding control signals and - via a line connection - can be acted upon by the relevant blowing device 113q. Although in the following the switching means 116 are designated as valves 116, the above-mentioned can basically also be applied to other designs.

About a printing professional falling from the inside out, i.e. the profile in the force effect K (see e.g. schematic Fig. 28 ) to favor the bow B, a line leading the blown air from the respective switching valve 116 to the blower tube 113q leads preferably within a central longitudinal section, e.g. B. within the length of the two inner quarters, in the blown air-carrying interior of the blow pipe 113q. In the case of two switching valves 116 or feeds to the blowpipe 113q, this applies to both, the inside of the blowpipe 113q in the area between the two feeds by one Wall can be divided.

A plurality or all of the blown air openings 114r of the blown device 113q can be assigned an adjusting means (not specified in more detail), by means of which the blown air flow and thus also the pressure profile can be set and / or varied. These can be screw plugs, for example, which protrude into a line cross section of a line duct leading to the blown air opening 114r, and the position of which allows the opening cross section to be varied for the flow. In this case, it is desirable, for example, for the pressure profile to drop outward in terms of the force effect, the specific shape being able to depend on the printing material and / or the conveying speed v32. A desired setting of the pressure profile can also be realized without further adjusting means by the position of the blown air supply in the blower tube 113q, by the position and size of the blown air openings 114r and by the choice of the free cross section or a varying course.

Basically, the individual upper groups, groups 113q or subgroups 113q1; 113q2 of valves 116 assigned to blown air openings 114, for example in the manner of a valve terminal, can be combined centrally at one point. In a preferred embodiment, however, the valves 116 are decentralized and / or at least in groups or preferably all spatially spaced from one another, in particular in each case close to the assigned upper group, group 113q or subgroups 113q1; 113q2 arranged. The valves 116 are, for example, each arranged closer to the inlet 121 in the associated blowpipe 113 than to the inlet in the other blowpipe 113. At least, however, they are arranged closer to an inlet 121 in the assigned blowpipe 113 than half the distance between the two most widely spaced blowing air nozzles 114 of the associated blowing pipe 113.

The supply of the blowpipes 113q, that is to say the upper groups, groups 113q or in particular subgroups 113q 1; 113q2 or the upstream valves 116 takes place from a source 119 via a blown air path, which can be formed by serial and / or parallel line paths. For example, a line coming from a compressed air source can open into a line 117 running transversely to the transport direction T, which line is formed, for example, by a hollow, transverse traverse 117 or is integrated into such a crossbar. From the transverse line, a passage can be made in at least one longitudinal line 118 running parallel to the transport direction T, e.g. B. longitudinal distributor 118, which can be formed by a hollow, longitudinally extending support 118 or can be integrated in such a longitudinal support. In an advantageous embodiment, two such hollow longitudinal members 118 can be provided for guiding the blown air. Branches 122 for supplying the upper groups, groups 113q or, in particular, subgroups 113q 1 go from this longitudinal member 118 or these longitudinal members 118; 113q2 or the upstream of these valves 116. A branch is preferably assigned to each of the blowing devices 113q designed as blowing pipes 113q. The source 119 can also be a compressed air source 119 provided for other applications of the machine 01.

In an advantageous embodiment, the line path from the source 119 to that of an upper group, a group 113q or a subgroup 113q1; 113q2 associated valves 116, in particular between the branch 122 from the longitudinal distributor 118 and the at least one downstream valve 116, an actuator 124 regulating the inlet pressure Pe on the inlet side to a desired outlet pressure Pa, e.g. B. a pressure control valve 124 is provided. By means of this actuator 124, the pressure to be switched downstream via the valve 116 can be adjusted and / or varied, preferably remotely and / or automatically. Are several of the same group 113q or one same blowpipe 113q, z. If, for example, two valves 116 and inlets 121 are assigned, the valves 116 assigned to this same group 113q can be supplied with blown air via a same branch and via a common actuator 124.

At least or exactly one such actuator 124 can be provided per upper group or preferably per group 113q or per blow pipe 113q. A profile for the blowing action along the transport direction T can thus be set and / or varied.

For example, the actuator 124 can be used to regulate the pressure to a pressure on the outlet side of between 0.6 × 10 ⁵ and 1.8 ^∗ 10 ⁵ Pa, in particular between 1.0 ^∗ 10 ⁵ and 1.5 ^∗ 10 ⁵ Pa. In an advantageous embodiment, an overpressure pressure of 1.2 ^∗ 10 ⁵ ± 0.1 ^∗ 10 ⁵ Pa is present on the output side of the pressure control valve 124 and / or on the input side of the switching valve 116. In a preferred embodiment, when the valve 116 is activated, that is to say open, there is a pressure P in the downstream blow pipe 113q greater than 0.6 ^∗ 10 ⁵ and 1.8 ^∗ 10 ⁵ Pa, in particular between 1.0 ^∗ 10 ⁵ and 1.5 ^∗ 10 ⁵ Pa , preferably 1.2 ^∗ 10 ⁵ ± 0.1 ^∗ 10 ⁵ Pa. When the switching means 116 is activated or when the valve 116 is opened, air at a pressure greater than 0.6, in particular between 1.0 ^∗ 10 ⁵ and 1.5 ^∗ 10 ⁵ Pa, flows, at least briefly, in particular under a pressure of approx. 1.2 ^∗ 10 ⁵ , ie 1.2 ^∗ 10 ⁵ ± 0.1 ^∗ 10 ⁵ Pa, of standing air as blowing air from the blowing air openings 114r. The transverse blowpipes 113q or the blown air openings 114r are thus with compressed air of a pressure greater than 0.6 ^∗ 10 ⁵ Pa, in particular between 1.0 ^∗ 10 ⁵ and 1.5 ^∗ 10 ⁵ Pa, preferably 1.2 ^∗ 10 ⁵ ± 0, 1 ^∗ 10 ⁵ Pa, supplied or acted upon. The information on pressure given here means the overpressure compared to normal pressure, ie 1.013 ^∗ 10 ⁵ Pa.

In the line path from the source 119 to the valves 116, in particular to the longitudinal distributor 118 arranged upstream of the valves 116, an adjusting means 123 which limits the pressure of the source 119, in particular a pressure reducer 123 which limits the pressure of the source 119, can be provided. For example, an output pressure of a maximum of 2.0 ^∗ 10 ⁵ Pa, z. B. in the range of 1.0 ^∗ 10 ⁵ to 1.5 ^∗ 10 ⁵ Pa, in particular from 1.2 ^∗ 10 ⁵ ± 0.1 ^∗ 10 ⁵ Pa provided pressure reducer 123 or the pressure reducer 123 is operated accordingly.

Regardless of whether pressure regulating valves 124 are provided, one is therefore one Blower device 51 having blown air openings 114r; 52 provided, the input side with compressed air a pressure greater than 0.5 ^∗ 10 ⁵ Pa, z. B. a pressure between 0.6 and 1.8 ^∗ 10 ⁵ Pa, is supplied or is. The blowing device 51; 52 is thus on the input side with compressed air with a pressure greater than 0.5 ^∗ 10 ⁵ Pa, z. B. a pressure between 0.6 ^∗ 10 ⁵ and 1.8 ^∗ 10 ⁵ Pa, providing compressed air source 119 in line connection. In the case of sufficiently large line cross-sections up to the blown air openings 114r, in the activated state of the relevant valve in the blown tube, ie on the inner side of the blown air opening 114r, blown air with an approximately the same pressure, ie a pressure greater than 0.6 ^∗ 10 ⁵ Pa, e.g. B. a pressure between 0.6 ^∗ 10 ⁵ and 1.8 ^∗ 10 ⁵ Pa.

In a preferred embodiment of the blowing device 51; 52, in particular in connection with an arrangement above a first of a plurality of delivery stations I; II, the blowing devices 113q, which are arranged one behind the other and extend transversely to the transport direction, are activated and deactivated individually or in upper groups, depending on the transport destination provided for the sheet B _i entering the delivery station I, such that only those in the area thereof Delivery station I sheets B to be deposited are blown with air from above. Basically, the transverse blow devices 113q or blow pipes 113q can be activated and deactivated together depending on the transport destination. This could be done via a common switching means 116, which is controlled by a control device comprising control means S116.

In a preferred embodiment, the blowing devices 113q or blowing pipes 113q are activated and deactivated for the sheet B to be deposited in synchronization with the advance of the sheet B to be deposited. The blow devices 113q or blowpipes 113q are synchronized, for example, with respect to the point in time and the duration and / or activated and deactivated in a correlation to a machine and / or printing material phase position Φ, ie clocked with the printing material flow. For example, the blowing devices 113q or blowing pipes 113q for a sheet B to be deposited can be switched on successively starting with the front edge thereof. If several overlapping sheets B are to be deposited one after the other, then the blowing devices 113q or blowing tubes 113q remain activated. In the case of sheet B overlapping in the printing material flow, the blowing devices 113q or blowing pipes 113q are only deactivated again, for example one after the other, starting with the front edge of a first sheet B to be transferred.

In the case of a stream of sheets overlapping like a scale, the blowing device remains inactive for a series of sheets B to be transferred.

For the alternative case of sheet B conveyed without overlap, the blowing devices 113q or blowpipes 113q activated for the sheet B to be deposited can be deactivated again successively by sweeping over the rear edge thereof. For the next sheet B, depending on its transport destination, either a successive activation or a transfer with an inactive blowing device 51; 52 performed.

The blown air openings 114r of the blower tubes 113q, in particular transverse blower tubes 113q, are or are operated individually, in groups or as a whole depending on the respective transport destination, i.e. whether the arriving sheet B is to be deposited or transported further, in such a clocked manner that only the in the delivery station I located below sheet B to be deposited with blowing air.

The pressure control valves 116 mentioned, for example, optimize and, if necessary, correlate the transport speed to regulate the pulse generated by the blown air.

For transport destination dependent and / or successive wiring, ie activation and Deactivation of the switching means 116 is, for example, in signal connection with the above-mentioned control means S116, which are designed and set up for this purpose, activating and deactivating the switching means 116 and / or selecting an operating mode for operating the blowing device 51; 52 depending on the transport destination to the delivery station I; II to cause incoming sheet B. Instead or in addition to this, the control means S116 are designed and set up to synchronize and / or to effect an activation and deactivation of the switching means 116 and / or in a correlation to a machine and / or substrate phase position Φ. A distinction can be made between two operating modes, a first operating mode relating to a sheet B to be deposited and a second operating mode relating to a sheet B to be transferred. In the first operating mode, the blowing devices 113q or blowing pipes 113q are activated simultaneously or successively; in the second operating mode, at least the blowing devices 113q or blowing pipes 113q at the respective time above the sheet B to be transferred are or are deactivated during the transfer.

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

The control means S116 are preferably in signal connection with a signal generator, e.g. B. a sensor or a drive master, from which they receive the machine and / or substrate phase position and / or represent information I (Φ).

In principle, the previously mentioned blowing devices 113q, which are in particular designed as blowing pipes 113q, can also extend in the transport direction and can be arranged next to one another in a plurality transversely to the transport direction T. It can then with appropriate arrangement of the blowpipes 113q and those provided in them Blown air openings 114 may be able to implement a similar pattern of blown air outlets. A variability given in time and / or in the strength of the effect in the transport direction T is then not given or not to the same extent as in the case of the transverse blowpipes 113q.

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

The at least one longitudinal blowing device 126 can be supplied via a line connection from the same source 119 - possibly via the same or a further pressure-limiting actuating means 123; 128, e.g. B. pressure reducer 123; 128. With or without an upstream actuating means 128, an actuator 129, e.g. B. a pressure control valve 129 may be provided. Preferably, there is blow air in the longitudinal blowing tube 126 with a higher pressure than the blowing air of the transverse blow tubes 113q, e.g. B. a pressure of at least 4 ^∗ 10 ⁵ Pa, preferably of at least 5 ^∗ 10 ⁵ Pa. Due to the central arrangement and the high pressure, sheets B can be stiffened by central "breaking" for the purpose of sheet storage.

The at least one longitudinal blowpipe 126 is or is operated according to a pattern comparable to the transverse blowpipes 113q, also clocked, depending on the respective transport destination, in such a way that only the sheets B to be deposited in the dispensing station I below are subjected to blowing air.

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

In particular in connection with the design of the delivery device 03 as a multiple stack delivery 03, in particular a double stack delivery 03, the blowing device 51 is designed and set up to selectively apply blowing air to a single or a series of sheets B from a stream of a batch and the remaining sheets B let the sheet relay pass without being applied.

By the blowing device 51; 52 can be individual, in particular sheets B to be deposited are specifically provided with a strong impulse. This enables storage even at high conveyor speeds v32 and / or a high sheet frequency. By deactivating the blowers 113q; 126 for sheets B to be transferred, these are not pressurized with air and therefore do not receive any impulse. As a result, the possibly disrupted running of the sheet B to be transferred does not become unnecessarily uneasy and contact with the stack underneath can be avoided.

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

In an embodiment which is advantageous with regard to the stack quality of the first stack 11, the or a part of the blowing air openings 114r which are provided one behind the other in the transport direction T and which are to be activated independently of one another, in particular transverse blowing devices 113q or blowing pipes 113qq each comprising a plurality of blowing air openings 114r, are in an operating phase of the above-mentioned second operating mode, in which, for. B. one or more sheets B entering the first delivery station I are to be transferred or transferred in accordance with the first operating mode, so acted upon with blown air or activated and deactivated such that they merely - at least for a time interval or temporarily - into the gap between successive sheets B, in particular into the gap between the trailing end 11 of a sheet B and the holding device 32 of the following sheet B _n ; B _{n + 1} , in particular the gripper carriage 32 transporting the following sheet B, blow.

In this operating situation, the blowing devices 113q or blow pipes 113q located at the respective point in time over the sheet B to be transferred and moved in the transport direction T are deactivated, but those with the progress of the sheets B are or become in each case for a time window over a gap between one another following sheet B, in particular in a gap between the trailing end 11 of a sheet B and the holding device 32 of the following sheet B, lying blowing devices 113q or blowing pipes 113q successively activated for at least one time interval lying within this time window.

The valve 116 assigned to the blowing air openings 114r or blowing devices 113q, which can be activated independently of one another, are in signal connection with a control means S116, which in turn is in signal connection with a signal transmitter providing and / or representing information relating to the machine and / or substrate phase, and is designed and set up to activate the blown air via the valves 116 as a function of the information I (Φ) relating to and / or representing the machine and / or substrate phase in such a way that blowing only occurs within a gap between two successive ones sheet B not to be filed.

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

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

A further development is advantageous, according to which a number of blowing devices 113q which simultaneously blow into the same gap vary or can vary with the format length of the printing material sheets B. For example, for a longer format, the gap is blown into the gap simultaneously with a first number of successive blowing air openings 114r or blowing devices 113q (see, for example, 29 a) to c) while for a shorter format with a higher number of consecutive blowing air openings 114r or blowing devices 113q, the larger gap is blown (see e.g. Fig. 29 a) to c).

In a further development, the effect of the blow devices 113q or blow pipes 113q can be adjusted in their width and / or position viewed transversely to the transport direction T. For this purpose, e.g. B. external sections can be permanently deactivated or deactivated, in particular switched off or switched off. For example, individual blown air openings 114r can be closed by an adjusting means (not shown in more detail)

Together with one or more features of the sheet guiding device 47 and / or the braking device 48; 49 and / or to the blowing device 51; 52 and / or to the start-up section 78 or also considered on its own, a particularly preferred device 139 for releasing the conveyed sheets B, briefly releasing device 139, comprises a switching device for releasing conveyed printing material sheets B with an actuating device 143, by means of which the release in Area of the assigned delivery station I; II can optionally be activated and deactivated, and with an actuating device 144, through which, viewed in the direction of transport T, the location ^∗ _{39 of} the sheet release, in the case of grippers 56 Holding elements from the gripper opening point called location ^∗ ₃₉ , in the area of the assigned delivery station I; II can be adjusted or varied. The two actuators 143; 144 are hereby actuated by drive means 146; 147 adjustable. The release device 139 is thus designed to activate or deactivate the switching device 141, 142, in particular to engage or disengage switching means 141; at a specific point in time - for example between two holding means 32, in particular gripper carriages 32, which follow one another in the transport direction T. 142 of the z. B. mechanically executed switching device 141, 142 to effect.

A particularly advantageous embodiment of the delivery device 03 in this context has a conveyor system 21 comprising at least one holding device 32, through which a printing material sheet B can be picked up and downstream to a delivery station I; II is conveyable, where it can either be released by the holding means 32 and delivered to a stack 11, 12 to be formed, or can be conveyed further downstream. It further comprises a switching device 141, 142 which effects the delivery and which switches one of the delivery stations I; II comprises functionally and / or spatially assigned switching cams 141 and a cam follower 142 functionally and / or spatially assigned to the holding means 32, the cam follower 142 acting - directly or indirectly - on its actuation on at least one holding element 56 of the holding device 32.

Although the cam follower 142 could in principle also slide together with the switching cam 141, it is preferably designed as a roller lever 142 and interacts with the switching cam 141 with a roller encompassed by the cam follower 142.

For activation and deactivation of the release, the switching cam 141 is optionally inserted into the undisturbed movement path 152 of the cam follower 142 by an actuating device 143 acting on the switching cam 141. and can be brought out again, in particular pivotable. The pivoting preferably takes place about a pivot axis A141 that is perpendicular to the transport direction T and that is fixed with respect to a spatially fixed frame G of the delivery device 03.

To vary the transport path-related location of the release to be effected by the switching cam 141, a contact point 151 for the first contact between the switching cam 141 and the cam follower 142 to be moved in the transport direction T on the switching cam 141 - z. B. within at least one viewed in the transport direction, in particular as a control section effective longitudinal section - variable by a second cam 144 engaging on the switching cam 141, different from the first actuating device 143.

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

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

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

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

For this purpose, the first actuating device 143 engages at a first engagement point P143 of the release cam 141 and the second actuating device 144 at a second engagement point P144 spaced apart in the transport direction T.

The switching cam 141 is by the second actuator 144 z. B. pivotable about a second pivot axis A144 lying in the point of engagement P143 of the first adjusting device 143. The second pivot axis A144 or the first point of engagement P143 can be displaced radially by the first adjusting device 143 and / or the first drive means 146, in particular around a frame G which is fixed in space

Delivery device 03 swivel axis A141 fixed to the frame.

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

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

In an advantageous embodiment, the hydraulic or preferably pneumatic cylinder 146 is double-acting, i. H. Pressurized in both directions.

The double-acting design and / or the arrangement of the valve close to the drive means creates a particularly fast and precise-acting switching drive.

By defining and / or defining two fixed end positions in the drive train of the first actuating device, for example, switching cam 141 can be switched on and off very quickly, but exactly, ie activating and deactivating release device 139 quickly and precisely.

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

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

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

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

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

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

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

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

However, an embodiment is of particular advantage in the drive train

Actuating device 144 in addition to at least one single-arm or multi-arm lever 163 which can be pivoted about a pivot axis A149 fixed to the frame; 164 comprises a coupling 162 which is connected in an articulated manner at both ends. In an advantageous and illustrated embodiment, the drive means 147 engages a lever 162 which rotates on a shaft 147 pivotable about the pivot axis A149, e.g. B. og. Synchronous shaft 147 is arranged. A further lever 164, which is arranged on the shaft 157 in a manner fixed against rotation, drives the drive directly or indirectly via a joint on the coupling 162 and, via a further joint, directly or indirectly on the second point of application P144.

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

To control the switching cam 141 either into the movement path 152 of the cam follower 142 or completely out of motion drive means 146 and / or a switching means 153 switching the drive means 146, this is in signal connection to a control means S146, which in turn is in signal connection with the machine and and / or representative information I (Φ) supplying and / or representing the substrate phase position, and is designed and set up for this purpose, activating and deactivating the drive means 146 and / or a switching means 153 switching the drive means 146 in a correlation to a machine transmitted by a signal generator - and / or substrate phase position Φ too effect.

In order to control the drive means 147 and / or a switching means switching the drive means 147, which varies the switching cam 141 with respect to the delivery location, the latter is in signal connection to a control means S147, which in turn is in signal connection with information I relating to the machine or transport speed and / or representing it (Φ̇) delivering signal transmitter and is designed and set up to cause the drive means 147 and thus the gripper opening point to be set in a correlation to a machine and / or substrate phase position Φ transmitted by a signal transmitter.

During the infeed and shutdown movement, the other effective switching state should be reached as quickly as possible for high production or conveying speeds, e.g. B. be completed within at most 150 ms, preferably within 130 ms.

For this purpose, an actuating movement on both sides preferably does not take place via mechanical synchronization, but preferably via respective drive means 146. Instead or in addition to this, delays at the end of the line due to the shortest possible cable paths are advantageous, as they are e.g. B. with the short fluid lines 154; 156 are set out above. As an alternative or in addition to the above-mentioned advantageous restriction of the length of the line path, the length of the respective line is selected such that the dead volume enclosed in the respective pressurized supply line is not more than 25% of the volume stored in the extended cylinder, which is due, for example, to the piston stroke of the extended cylinder multiplied piston cross-section is given. In a particularly advantageous embodiment, this dead volume is less than 10%. In a further development, the valve 153 being mounted directly on the cylinder 146 or even being integrated in the cylinder 146, this value can be reduced to less than 5%, in particular to less than 2%.

In order to minimize control-based dead times, the control means S146 controlling the deactivation / activation are provided with a fast switching logic, i. H. a switching logic, a signal relating to the machine and / or substrate phase position of an o. g. Signal generator directly without delay, i. H. in particular, not only via clocked processing, such as is carried out, for example, in PLCs and possibly clocked bus systems, is processed and transmitted to a signal σ147 which drives the drive means 147 or triggers the activation or deactivation. The fast switching logic switches the actuating device 143 activating and deactivating the switching device 141, 142 with machine angle accuracy.

Instead or in addition to one or more measures for minimizing the dead time, a - preferably machine speed-dependent - dead time compensation can be provided, which z. B. compensated for inertia still existing dead time by appropriate feedforward control. In this case, for example, the machine and / or substrate phase position correlated with the possible switching time can be moved forward according to the dead time to be taken into account. In a preferred development, the degree of advance can be varied depending on the transport speed, so that, for example, the triggering machine and / or substrate phase position is moved further forward at a higher speed than at a lower transport speed. It is thus possible to always start the actual movement of the switching cam 141 for different machine speeds or speeds in the same or at least essentially the same machine and / or substrate phase position.

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

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

The activation and deactivation is preferably carried out by pivoting the switching cam 141 about a first pivot axis A144 fixed to the frame. The switching cam 141 is preferably varied by varying the distance between at least one of its ends related to the transport direction T and the movement path 152 of the cam follower 142.

In a particularly advantageous development, the switching device is controlled 141, 142 such that the switching cam 141 is in its first operating position, ie in an active position, at least at one point in time, while the above-mentioned blowing device is operated in the first operating mode and / or the above-mentioned braking device 48; 49 is operated in the first operating mode m1.

The control panels 243; Although 244 can in principle be provided on the long side, they are advantageously located in the area downstream of the second delivery station II, preferably on the end face of the delivery device 03 opposite the sheet entry.

For this purpose, the respective control panel 243; 244, e.g. B. control panel 243; 244, on the one hand first switching elements 228; 229, by actuating which a value of a variable to be set can be entered and / or changed. This can be keys of a keypad for entering the value or - such as. B. shown here - Plus and minus buttons for increasing or decreasing the current value step by step. In addition, the control panels 243; 244 at least one switching element 246; 247, by its actuation for the control panel 243; 244 assigned delivery station I; II a signal connection between the first switching elements 228; 229 with the drive of a device 48; 49 of the relevant delivery station I; II can be manufactured or activated. In the case of a plurality of devices 48; 49; 139 at one or all of the delivery station I; II, includes the associated control panel 243; 244 one or more such switching elements 246; 247, by actuating them for the assigned delivery station I; II a signal connection between the first switching elements 228 relating to the value of the variable to be set; 229 with optionally the drive of a first device 48; 49 of the assigned delivery station I; II or the drive of a second device 139 can be produced or activated.

The switching elements 228; 229 are thus here by corresponding activation on the respectively assigned control panel 243; 244 by corresponding activation in a signal-technical active connection with drives of the above-mentioned different quality-relevant devices 139; 48 of the first and second Delivery station I; II transferable. Switching elements 246; 247 provided, by actuating the device 139; 48; 49 can be selected.

In order to assign the control panels 243; 244 to the delivery station I; II facilitate, the control panels 243; 244 each have a marking 251 relating to the assignment; 252 have. In principle, this can be of any design, but is numerical here, for example, by specifying the downstream position in the row of the intended delivery station I; II executed (see e.g. Fig. 47 ).

The two control panels 243; 244 form an operator interface 253, in particular on the front side, or are encompassed by such an operator interface 253 in addition to any further actuating means which may be in the immediate vicinity.

Basically independent of the specific design of the above-mentioned control and setting 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 on the end face to the delivery device 03, the delivery stations I; II each have at least one z. B. Above device 48; 49; 103; 139 is assigned to the delivery stations I; II each assigned at least one device (48; 49; 103; 139), which is designed with a view to adapting or correcting the sheet guidance and / or placement by drive means 63; 106; 147; 202 comprehensive drives can be set, is at least one user interface 232; 253 with at least a 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 actuation via a first signal connection 257; 261 a drive means 63; 106; 147; 202 of a device 49; 103; 139 of the second delivery station II; I and via a second signal connection 258; 262 a drive means 63; 106; 147; 202 a functionally of the device 49; 103; 139 of the second delivery station II; I corresponding device 48; 103; 139 of the first delivery station I; II is adjustable or adjustable, in particular can also be set or set.

When setting the at least one first delivery station I; II and one of the first delivery station I; II downstream downstream delivery station II in the transport path; I comprehensive delivery device 03 for delivery of printing material sheet B is used to adapt or correct the sheet guidance and / or storage in the second delivery station II; I at least one device 48 that can be set with regard to an adaptation or correction of the sheet guidance and / or storage in the second delivery station II; 49; 103; 139 set or set, and as a result of and / or with the setting or setting of this device 49; 139 of the second delivery station II also a setting or setting of a function of the device 49; 103; 139 device 48 corresponding to the second delivery station II; 103; 139 of the first delivery station I; II takes place.

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

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

The device 48; 49; 103; 139 can in this case be fundamentally different and / or geometrically arranged, the specific design then being taken into account when the carried quantity is set. The devices 48; 49; 103; 139, at least what the mechanism of the setting variable X ₉₁ ; v _from ; * ₃₉ ; Y ₂₀₁ concerns, carried out in the same way. As a result, no complex relationships need to be taken into account when setting, but - if desired - an absolute and / or an offset proportional to the level of the manipulated variable.

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

The relationship 256 or the provision 256 is in particular set up and programmed to measure or set the device 48 assigned to the first delivery station I; 103; 139 on the basis of the relationship 256 stored in the device 49; 103; 139 of the second delivery station II to be determined and the drive of the first delivery station I; II concerned device 48; 49; 103; 139, ie directly to the drive means 63; 106; 147; 202 or the control means S63; S106; S147; S202, to be acted on (see e.g. Fig. 49 ).

Such a modification of the value via a relationship 256 - z. B. via an absolute and / or an offset proportional to the level of the manipulated value - preferably takes place when setting or setting format-relevant, d. H. devices 103 to be adapted to the respective format; 48; 49, e.g. B. when setting the side stop device 103 laterally and when setting the at least one braking device 91 in the transport direction T. It is particularly advantageous if the setting of the device 103; 48; the first delivery station I; II so that the setting there is an oversize in format compared to that setting at the first delivery station I; II for the actual format. The stack quality may suffer, but this reduces the risk of a malfunction during storage.

On the other hand, for devices 48; 49; 139, e.g. B. for setting the depositing speed v _ab on the braking device 48; 49 and / or the setting of the release location on the release device 139 - at least as far as the setting result to be achieved - is in a 1: 1 relationship. In this context, the relationship 256 can directly represent the 1: 1 relationship or take into account any correction that may be necessary due to different conditions in the execution.

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