Dies können wie am Beispiel der 1 zwei Weiterbearbeitungs- und/oder Auslagezweige 17; 18 und eine diesen Weiterbearbeitungs- und/oder Auslagezweigen 17; 18 zu- bzw. vorgeordnete Produktweiche 02 sein. Durch die Produktweiche 02 wird in einer Betriebsweise dann beispielsweise abwechselnd ein Produkt 01 in den einen und das nachfolgende Produkt 01 in den anderen Weiterbearbeitungs- und/oder Auslagezweig 17; 18 geleitet.The finishing and / or display section 19 or the further processing and / or display unit 19 has several, z. B. n (with n ε

n ≥ 2), ie at least two further processing and / or delivery branches 17 ; 18 and at least one product switch set forth below 02 , z. B. n - 1 such product switches 02 , on. These can be like the example of 1 two further processing and / or delivery branches 17 ; 18 and a these processing and / or delivery branches 17 ; 18 upstream or upstream product diverter 02 be. Through the product diverter 02 In one mode of operation, for example, a product then alternates, for example 01 in one and the following product 01 in the other processing and / or display branch 17 ; 18 directed.

Of particular advantage is the following set forth embodiment of the product diverter 02 in an embodiment of the printing press or with an embodiment of the folder 16 or the further processing and / or delivery section 19 given in which three or more (n = 3 or n ≥ 3) further processing and / or display branches 17 ; 18 ; 34 and two or more (n-1 with n = 3 or n ≥ 3) product switches 02 are provided. So z. B. 8th in addition a third processing and / or delivery branch 34 with another conveyor line 36 with z. B. a conveyor 37 , z. B. a tape system 37 , preferably a paddle wheel 38 and Z. B. a display 39 and possibly one of the displays 39 upstream further processing stage. In case of more than two further processing and / or delivery branches 17 ; 18 ; 34 are the product switches 02 and conveyor lines 03 ; 06 ; 08 ; 36 ; 42 preferably such -. B. cascaded - arranged so that at the respective product diverter 02 the one single processing and / or delivery branch 17 ; 18 ; 34 supplied products 01 discharged and the corresponding conveyor line 06 be fed and the residual current either on a conveyor line 42 to the next product diverter 02 or in the case of the downstream product diverter considered downstream 02 the last further processing and / or display branch 34 or its conveyor line 36 is supplied. The product flow thus becomes each product diverter 02 divided into only two sub-streams. As a result, in the case of more than two processing and / or display branches 17 ; 18 ; 34 in at least one mode of operation at least downstream of the first product diverter 02 the product stream is split or split in a pattern deviating from the one-to-one division. In the example of three further processing and / or delivery branches 17 ; 18 ; 34 is in this mode, for example, on the first product diverter 02 to perform a 1: 2 division, where a product 01 in the corresponding first processing and / or display branch 17 ; 18 ; 34 to divert and the next two products 01 in the feed stream for the next product diverter 02 to be left.

A division into two or more processing and / or display branches 17 ; 18 ; 34 accomplishing splitting device comprises at least one product diverter 02 , z. B. one or two product switches 02 , for splitting the product flow into two partial streams, each product diverter 02 an actuator 44 . 48 . 49 for placing the at least one product diverter 02 or their guide element 43 and control means 46 . 47 for the operation clocked driving the respective actuator 44 . 48 . 49 the relevant product diverter 02 or all in the further processing and / or display section 19 provided product switch 02 ,

The product diverter 02 comprises at least one guide element arranged so movably in the product path 43 , z. B. engaging in the product path tongue 43 so that the incoming product 01 depending on the position of the guide element 43 in one or the other conveyor line 06 ; 08 ; 36 ; 42 is directed. For example, one product alternately can be used 01 in one or the other of two conveyor lines 06 ; 08 respectively. 06 ; 42 respectively. 08 ; 36 and two different further processing levels and / or expenses 11 ; 12 ; 39 feed (see eg 1 and 8th ). In another version can be at a first product diverter 02 every third product 01 spill while the remaining products 01 z. B. to the second product diverter 02 where they eventually take turns in the second and third conveyor 08 ; 36 be split up (see eg 8th ). The guiding elements 43 is therefore correlated in each case, in particular synchronously, to the beat of the relevant further processing and / or display branch 17 ; 18 ; 34 products to be rejected 01 to move back and forth. Is every second product 01 to be discharged, is ever auszuschleusendem product 01 the guiding element 43 once moved between the two positions back and forth. The same applies to the discharge of every third or even fourth product 01 ,

The movement of the guide element 43 takes place by means of a drive means 44 , in particular an actuator 44 which correlates, in particular synchronously, with the clock of the incoming and outgoing products 01 by appropriate control means 46 . 47 thus activated (or deactivated) or acted upon with working fluid, so that it is in the frequency of the auszuschleusenden products 01 performs at least one adjusting movement, in particular a cycle of movement passes between two actuator positions, which the two points settings for the two alternative conveyor lines 03 ; 06 ; 08 ; 36 ; 42 assigned. As an actuator 44 is a - in particular linear acting - pull and / or pressure actuator 44 intended. This attacks, for example via a transmission 48 . 49 on the guide element 43 to his movement. The gear 48 . 49 can in an advantageous embodiment z. B. by a on a shaft 48 attacking lever 49 , in particular lever arm 49 , be given, wherein the guide element 43 rotationally fixed - z. B. by terminals and possibly additionally an anti-rotation - on the shaft 48 is arranged. The wave 48 is here in or on a frame 54 to a z. B. parallel to the transport plane of the incoming products 01 , In particular about a horizontally extending pivot axis S pivotally mounted. The pivot axis S extends in one with the transport plane and / or surface of the incoming products 01 coincident or a plane parallel thereto and is perpendicular to the transport direction T. It may preferably in the axial direction a plurality of guide elements 43 rotatably with the shaft 48 be connected.

Basically, the actuator 44 in any way as an actuator providing non-zero travel 44 , z. B. as an electromagnetic or fluid-operated pressure and / or Zugaktuator 44 , z. B. in the manner of a linear drive, be formed. In both cases is a control device 46 provided, which at its output to an actuator 47 for the actuation of the actuator 44 acts. In the case of an electromagnetic linear actuator is the actuator 47 for example, given by a power command converting the power electronics. In the preferred case here as a fluid-operated drive, in particular as a fluid-operated linear drive, trained actuator 44 is the actuator 47 for example, by at least one remotely operated switchable valve 47 given, which by the control device 46 as a result of a logic implemented there 61 , z. B. in a suitably trained control circuit 61 or an implemented software algorithm 61 in a computer program, via a corresponding signal connection can be controlled. The valve 47 can be spatially on the actuator 44 or spaced therefrom. By placing the valve 47 is the fluid-operated actuator 44 in accordance with the control by the control device 46 optionally with pressure medium of a relation to the ambient pressure higher pressure P ⁺ , z. B. with by an appropriate source 50 Provided compressed air, acted upon and thereby activated. In an advantageous embodiment, the actuator 44 single-acting, ie acted upon in only one direction with force, as a tensile and / or pressure actuator 44 formed, which depending on the arrangement against a z. B. as a tension spring 51 or compression spring 52 trained spring element 51 ; 52 is working. In an alternative embodiment, a double-acting actuator 44 or it can, as exemplified below for the first embodiment, two oppositely acting, alternately activated actuators 44 be provided.

In a preferred embodiment in terms of power and dynamics, the actuator is the actuator 44 as a fluid-operated, in particular pneumatically operated contraction drive 44 educated. This is based on having a contraction tube 53 a certain length L53 when exposed to a pressure greater than the ambient pressure P ⁺ an enlargement of its cross-section in the radial direction, and concomitantly a corresponding shortening of its length L53 learns (see, eg. 2 and 3 ). The contracting drive 44 trained actuator 44 So that covers itself between two headers 56 ; 57 extending contraction tube 53 , which is radially expanded upon pressurization of its interior and thereby axially acting tensile forces between the headers 56 ; 57 causes each other. In a z. In 2 and 3 illustrated variant works the contraction drive 44 as Zugaktor against a tension spring 51 trained spring element 51 , In another geometry of the arrangement can as an "opponent" and a compression spring 52 be provided. The one of the head pieces 56 ; 57 is z. B. articulated with the frame 54 , the other of the head pieces 57 ; 56 z. B. articulated with the rotationally fixed to the shaft 48 connected lever 49 connected. Likewise, the spring element 51 ; 52 on the one hand with the frame 54 and at the other end with the lever 49 connected to its provision.

In a possibly more costly, in terms of dynamics and reproducibility u. U. even more advantageous embodiment variant (see, eg. 4 and 5 ) are two z. B. trained as Zugaktuatoren contraction drives 44 provided, which at the lever 49 , z. B. with at least one directional component, act upon activation in the opposite direction. This can be done for the two actuators 44 - As exemplified - two actuators 47 , in particular valves 47 be provided, which both by the control device 46 or the implemented logic 61 be controlled. When using each of its own actuator 47 For example, the second actuator 44 already shortly before deactivating the first actuator 44 activated (and thus biased). It can be used for commissioning the ideal wiring of the actuators 47 being found. In an alternative and possibly less expensive solution may also be a switching valve 47 with two pressure outputs as common actuator 47 Find application. For both contraction drives 44 is again one of the head pieces 56 ; 57 z. B. articulated with the frame 54 connected, ie on the frame 54 hinged, the other of the head pieces 57 ; 56 z. B. hinged to the non-rotatable with the shaft 48 connected lever 49 hinged, the two possibly articulated connections (linkages) to the frame 54 z. B. are arranged on both sides of a plane which is formed by the pivot axis S and the pivot axis S intersecting line of the physically effective lever ("effective" lever arm).

In an alternative, possibly cheaper version can be used as an actuator 44 a pneumatic cylinder 44 be provided (see, for example, 6 and 7 ), which in the above to the contraction drive 44 mentioned way on the one hand with the frame 54 and on the other hand with the lever 49 connected is. To arrange a lever 49 resetting spring element 51 ; 52 and to provide pressure across the valve 47 as well as the setting of the valve 47 via a control device 46 the above applies. Also, in an alternative, the second embodiment of the actuator 44 the above to the arrangement of two opposite to the lever 49 acting actuators 44 apply.

As already mentioned, one is on the actuator 47 the product diverter 02 acting control circuit 61 or one on the actuators 47 several product switches 02 acting common algorithm 61 , z. B. in a computer program, provided by which or which the signal technology with the control device 46 connected actuator 47 the product diverter 02 clocked, in particular synchronized, with a product flow oriented frequency and phase angle, is controlled. This can be the case in case of several product switches 02 be designed according to multiple. In an advantageous embodiment, however, in the case of several - z. B. cascaded in the product flow arranged - product shifts 02 a same control device 46 the actuators 47 several product switches 02 assigned together. In particular, one is on the actuators 47 several product switches 02 acting control circuit 61 or one on the actuators 47 several product switches 02 acting common algorithm 61 , z. B. in a computer program, provided by which or which the signal technology with the controller 46 connected actuators 47 each clocked, in particular synchronized, each with a product flow oriented frequency and phase position, are controlled.

The product flow oriented, in particular with this synchronized activation of the actuator 44 or control of the actuator 47 can be realized in different designs. Thus, for example, a frequency for the activation or activation can be derived from the current operating data of an electronic master axis synchronizing the drives of the printing press. The phase angle can be adjusted for example by the operator. In an advantageous embodiment, the required phase position between points position and product position using signals of the products 01 upstream of the product diverter 02 detecting measuring system 58 . 59 be determined and adjusted, for example, in addition an adjustment can be made by the operator. In this case, then, the controller 46 one the frequency and / or phase of the products 01 information concerning the product flow via a signal connection with the measuring system 58 . 59 be fed, which is merely a product diverter 02 or at least the first of several product switches 02 upstream in the product route. The signals of the measuring system 58 . 59 - z. B. a transmitter 59 (eg light source) and a receiver 58 (eg photoresistor), e.g. B. entry, passage or exit of the products 01 at the measuring point. These signals representing the frequency and / or phase of the product stream are preferably in the implemented logic 61 for controlling the actuator 47 or more actuators 47 used. Furthermore, in logic 61 for controlling the actuators 47 the pattern or the clock for the desired operation of the product switch 02 used. Preferably, in the case of several product switches 02 by the same control device 46 , in particular by one or more software algorithms 61 a same, in the control device 46 implemented computer program, the actuators 47 several actuators 44 or product switches 02 controlled. For example, is or is for a respect to the product flow first product diverter 02 a first, z. B. in the control device 46 stored factor representing the division (eg 1: 2), and for the second product diverter 02 one of these different second, z. B. in the control device 46 stored factor that takes into account the division (eg 1: 1) of the residual current. It should be noted that in the sequence of copies on the second product diverter 02 already every third product 01 is missing and only the residual current in the ratio 1: 1 is divided. The second product diverter 02 can therefore in the first product diverter 02 corresponding frequency, but around the phase of one or two products 01 be operated shifted or be. The factors can be kept changeable in an advantageous development via an operator interface by the operating personnel.

In the exemplary embodiment with more than two processing and / or delivery branches 17 ; 18 ; 34 and / or with more than one product diverter 02 is the finishing and / or display section 19 preceded by a printing machine with at least one printing unit whose imaging cylinder has a circumference, which more than two benefits or printing pages, z. B. three, four, five or six benefits or printed pages, one behind the other in the circumferential direction corresponds.
