Front edge and side edge alignment of a tabular good known, one Side mark can be formed as a side double mark with two side stop rollers mounted to oscillate about a common pendulum axis. Furthermore, a measuring device assigned to a feed drum can be provided for determining the lateral offset of the goods. In the case of scroll panels in particular, however, the side edge can only be insufficiently detected due to the present scroll cutouts.

The invention has for its object to provide an alternative sheet-like substrate processing machine with a system or an alternative method for setting up or operating a system of a sheet-like substrate processing machine. In particular, it is to be made possible to be able to detect an incorrectly aligned table, in particular a scroll table, preferably in the running process.

According to the invention, the object is achieved by a device with the features of the independent device claim and a method with the features of an independent method claim. Advantageous refinements result from the subclaims, the description and the drawings.

The invention has the advantage that an alternative sheet-like substrate processing machine is created with a system or an alternative method for setting up or operating a system of a table-shaped substrate processing machine. In particular, it is also possible to preferentially record an incorrectly aligned table, in particular a scroll table, in the running process.

In particular, in the case of a machine processing tabular substrates, for example a machine that processes optional panels or scroll panels, the panels or scroll panels are preferably aligned, for example on a feed frame, preferably while running at production speed and fed to a processing nip, for example a printing nip. The panels or scroll panels have a preferably oscillating side mark and a preferably oscillating side shift positioned. An alignment of a substrate lying against stops preferably takes place by moving the side mark and the side shift towards one another, in particular the side shift being designed to be resilient and the alignment thus taking place on the side mark.

Depending on the substrate properties or type of sheet to be processed, appropriate lateral guiding devices are used in particular in the machine system. A single roller device, for example an alignment roller, can be used for normal sheets, in particular normal sheet metal. Scroll rails, which in particular have a plurality of rollers arranged one behind the other, can be used for scroll panels, in particular scroll sheet metal. However, the use of a scroll rail makes sense both for scroll boards and for thin boards from, for example, approximately 0.18 mm. With thin panels in particular, the probability is high when using the single device that the panel bulges in the middle. The cause is the lateral force that is introduced at certain points. The scroll rail is better here, which has a larger extension

Lateral thrust is introduced and the panel is less prone to bulge, which would result in poor side registration. When using a scroll table, the individual roller devices in the system are preferably replaced by scroll rails, in particular on both sides.

The alignment of the sheets or scroll sheets in the system of the machine on the individual roller devices or on the scroll rails used is preferably carried out at full production speed by the in particular oscillating movement of

Sideshift and side mark, which are embodied either by the two single roller devices or the two scroll rails. Each panel or scroll panel is preferably aligned laterally to one another by a simultaneous movement of the individual roller devices or the scroll rails. Sensors are provided for at least one and preferably both side guide devices, which measure the position of a respective side edge.

However, measurements and evaluations are only made on the brand side.

For example, the brand side can be set on a control station of the machine, in particular the operating side or the drive side of the machine can be selected as the brand side. For example, an in particular analog measuring sensor can be provided, which is fixed or displaceable on the respective one

Side guide device is attached and can measure the position of the side edge. In particular, the use of at least one preferably optical sensor of a lateral guide device, in particular a scroll rail, takes place at least on the brand side. The sensor can be arranged, for example, displaceable, preferably displaceable, in and against the transport direction and can thus be set on a scroll tube of a scroll table. The or several sensors of a scroll rail preferably make the pivoting movement of the individual ball bearings.

A measurement is carried out particularly preferably in the case of panels or scroll panels aligned on the front edge, in particular in the case of a gripper closure, preferably by means of a

Gripper system of a cylinder, for example. For example, one or one of a plurality of sensors of an inserted scroll rail can be designed to be displaceable in order to carry out a measurement on a scroll tube, i. H. guarantee outside of scroll sections of a scroll table. Furthermore, one with the respective sensor on the

The evaluation device connected to the side guiding device on the brand side assess whether the board or scrolling board was set up correctly. An incorrectly aligned table or scroll table can be reliably detected in the running process. The connection of at least one sensor to the evaluation device can be wireless or, for example, wired using a plug contact.

Conveyors 2 are transported along a conveyor path in a transport direction T, on which they pass through one or more processing units or

Processing plants edited on at least one of their pages, e.g. B. printed and / or painted. The transport of the substrate, in particular of the panels 7, is preferably carried out without scaling, i. H. individually or with spaced substrates, in particular sheets 7. In order to ensure processing that is correct with respect to the longitudinal register, a cylinder can preferably be provided in at least one point in the conveying path

Leading edge alignment means, preferably leading edge stops, can be provided for register-correct alignment of the plates 7 conveyed on the conveyor section, in particular by a conveyor device 2 arranged upstream of the system 1 from a pressure cylinder 3. By cooperation of the conveyor device 2 which conveys the panels 7

Front edge alignment means, preferably stops, of a cylinder, in particular with contact marks 6 of a printing cylinder 3, the plates 7 can be applied in register and correctly aligned in the case of an inclined position. For this purpose, the conveying device 2 directly upstream of the cylinder, in particular the printing cylinder 3, is preferably operated at least at times at a higher feed or conveying speed than the peripheral speed of the cylinder, in particular printing cylinder 3. Due to this at least temporarily higher feed rate, a leading edge of the panels 7 is at least one stop surface of the

Front edge stops, in particular on the contact marks 6, pressed.

The conveying device 2 comprises at least one means which conveys the panels 7, for example circulating means or a revolving means which transports the panels 7

Funding. For example, it comprises a belt system with one or more z. B. designed as circulating belts circulating means, on which or which the plates 7 in the transport direction T by positive locking with a belt or a different, also rotating traction means arranged and attacking the trailing end of the plate 7 attack, z. B. rear thrust 8, or by

Non-positive connection (friction) with the belt system by only the dead weight or supported by measures to increase friction, e.g. B. by a support force and thus the friction increasing means, in particular by suppressing or a magnetic force, for example a magnet, in particular electromagnet, are promoted. The effect of the agent is preferably variable and / or can be optionally activated and deactivated.

The conveyor device 2 arranged upstream of the cylinder, in particular the pressure cylinder 3, can preferably be designed as a belt system having at least one revolving belt with a rear thrust 8. Suction devices and / or Guide surfaces may be provided. In order to avoid deformation of the plates 7 due to the differing speeds after the first contact on the abutment surfaces, the conveying device 2 can have means which limit the forces acting on the plate 7 for the feed. These means limiting the feed force can depend on the form of the conveying means

basically be implemented in different ways. In particular, the

Rear thrust 8 be sprung.

The table 7, which is directed by the conveyor device 2 to the cylinder, in particular the pressure cylinder 3, and which is aligned with leading edge stops, in particular the contact marks 6, is gripped by a gripper system 9 and moved further in the transport direction T. The table 7 passes through the machine in particular from the system 1 to a delivery in a particular straight transport direction T. In the delivery, the table 7 can be placed on a stack, for example. The panel 7 is in the machine a processing unit, for. B. at least one printing unit and / or at least one coating unit, in which the board 7 is printed or painted on at least one side. The processing unit or processing unit can, for example, be a printing unit which, in addition to the

Printing cylinder 3 can have a blanket cylinder 4 and a plate cylinder 5. In particular, an inking unit or inking and dampening unit can be assigned to the plate cylinder 5, which inked a printing plate mounted on the plate cylinder 5 in accordance with the printing ink used. When the plate cylinder 5 rolls on the rubber cylinder 4, the printing ink is transferred to the rubber cylinder 4, which is covered in particular with a rubber blanket. Between the

Rubber cylinder 4 and the impression cylinder 3, a printing gap is formed through which the plate 7 to be printed is conveyed. In the printing nip, the ink is from

Transfer blanket cylinder 4 to panel 7. The substrate to be processed, in particular a panel 7, can in principle also have paper material, for. B. a sheet of paper or cardboard of greater thickness,

for example up to at least 1 mm material thickness. However, the panels 7 are preferably rigid panels 7 or contain or consist of a rigid material. In particular, the panels 7 are metallic panels 7, in particular sheet metal panels 7. The panels 7 in the preferred sense here are characterized, for. B. in contrast to thin

Paper sheets, for example, characterized in that they have a considerably higher bending stiffness and / or a higher basis weight of z. B. have at least 1 kg / m ² , in particular 1 to 3 kg / m ² as thin sheets of paper. They are characterized, for example, by the fact that they are not wound on the curved surfaces of rotating transport cylinders or rollers, but rather by means of such rollers and cylinders, possibly with slight deflection and / or possibly a negligible wrap, e.g. B. over less than 20 °, are only transported essentially in a straight line. As panels 7 in this sense, therefore come in addition to the preferred embodiment as metal panels 7, z. B. metal sheets 7, for example made of tinplate or aluminum sheet, also sheets 7 made of more sensitive material such. B. panels 7 made of plastic, wooden, one

Composite or cardboard into consideration, especially if they z. B. in the above. Senses are rigid.

Fig. 2 shows a special board 7, as it can be processed in the machine, in particular printed and / or painted. The table 7 is a so-called scroll table 7, which preferably has at least one but two irregular side edges or

Has side surfaces. This means that one or both side surfaces of the scroll table 7 deviate from a particular vertical plane in particular. The two side edges each have scroll sections 7.1. Such scroll panels 7 also have to be aligned along the front edge, for example at the

Front edge stops, such as the contact marks 6, are also laterally aligned in order to be processed in register-correct manner, in particular printed and / or painted, to can. The dimensions shown are only examples and vary depending on the scroll panels 7 to be processed. This means that the scroll cutouts 7.1 are located at different locations as soon as the front edge of the different scroll panels 7 abuts front edge stops such as the front marks 6 . The material sections located between the scroll cutouts 7.1 and representing the side edges of the scroll table 7 are also referred to as scroll ears.

3 shows a system 1 for a machine processing tabular substrates, for example as described above. A conveyor device 2, which has a feed frame, is provided for table conveying. The feed frame is shown here in two parts, for example, each part being held in a manner such that it can be displaced transversely to the transport direction T, for example on cross members. Each part of the feed frame has, in particular, circumferential belts or suction belts, preferably with rear springs 8 which are in particular spring-loaded and not shown. To set the format, one or both subframes can be moved transversely to the transport direction T. Of the

Feed frame has a side guide for the tabular substrate, in particular the panels 7, on at least one and preferably both sides. In particular, the two parts of the feed frame each have base bodies 10 facing away from one another, to which side guide devices can preferably be assigned interchangeably. A respective base body 10 is adjusted with the respective part of the feed frame transversely to the transport direction T to the respective format. The base body 10 can, for example, be of mirror-symmetrical design.

FIG. 4 shows a perspective view of the system 1, the base body 10 assigned to the respective part of the feed frame for receiving a respective one

Lateral guide device are shown. A respective base body 10 is connected to a drive which can move the base body 10, which is held in particular on guide means, such as traverses, transversely to the transport direction T. From the drive, the respective base body 10 can in particular together with the part of the Feed frame for format adjustment to be positioned transversely to the transport direction T. A drive can also shift both base bodies 10 for format adjustment. Furthermore, one or the drive can be designed to generate an oscillating movement of one or both side guide devices. The oscillating movement of the side guide devices is preferably in phase opposition, ie

Lateral guiding devices move towards and away from each other at the same time. The oscillation movement or the stroke of the oscillation movement can also be made adjustable or changeable and is preferably implemented directly, in particular by the drive.

FIG. 5 shows a perspective view of the system 1 with the two parts of the feed frame, which carries the conveying device 2 for transporting the sheet-like substrate, in particular the sheets 7 or the scroll sheets 7. A respective part of the feed frame is assigned a base body 10 (not shown here), which is preferably positioned with the respective part of the feed frame transversely to the transport direction T for setting the format.

FIG. 6 shows the one assigned, for example, to the operating side of the machine

Base body 10, which is moved in particular to the format of the panels 7 currently to be processed and in particular remains there. A side thrust curve 12 is assigned to the base body 10, which oscillating movement on a

Intermediate plate 13 and a support plate 17 initiates and thus moves the intermediate plate 13 and the support plate 17. The side shift curve 12 can preferably provide an oscillating movement acting transversely to the transport direction T from a rotational movement over a contoured surface. The oscillating movement is preferably synchronized with the table run in such a way that each table 7 or scroll table 7 touches and is aligned with rollers of the side guiding devices at least or exactly once. The intermediate plate 13 and the support plate 17 are preferably each over two

Linear guides stored. The side thrust force is particularly preferably set by a pneumatic spring 16, which can comprise, for example, a pneumatic cylinder. The base body 10 can also have a stop 14 and / or a device for adjusting the side thrust 15. The device for setting the side thrust 15 can for example be one with a

Pneumatic cylinders have interacting travel limits. Via the device for setting the side shift path 15, a side shift path of, for example, max. 4 mm can be set.

A base body 10 for a side guide device, in particular a side mark, can be adjusted in the feed frame by means of a star grip screw 18 by tightening, a knurled nut 19 being provided for securing. This causes the intermediate plate 13 to be firmly connected to the support plate 17. A side shift, on the side opposite the side mark, in the feed frame can be set by loosening a star grip screw 18, for example> 6 mm, wherein a knurled nut 19 can also be provided for securing.

This causes the support plate 17 to move, for example, by max. Can shift 4 mm to the intermediate plate 13, in particular move. The advantage of this arrangement is the quick and tool-free changeover from side mark to side shift and vice versa. With a star grip screw 18

Intermediate plate 13 and the support plate 17 not only moved to block but

especially tense with each other. This ensures that the play on the brand side is pushed out of the linear guides and an optimal side registration is achieved.

A base body 10, preferably a support plate 17, can optionally have one

Side guide device are assigned, which either a single roller or a plurality or plurality of rollers for lateral guidance of the tabular Substrate, in particular the panels 7. In particular, both base bodies 10 are either used with a single roller device 25, preferably for guiding panels 7 having flat side edges or side surfaces, or side guide devices with a plurality or a plurality of rollers are used in each case. The side guiding devices with a plurality of rollers,

For example, two or at least three, preferably more than ten, particularly preferably more than twenty, rollers are used in particular for guiding panels 7 which are very thin and / or have no flat side edges or side surfaces. In particular, lateral guiding devices with a plurality of rollers are used for guiding scroll tables 7 with lateral scroll cutouts 7.1.

FIG. 7 shows a side guide device designed as a scroll rail 11, which can be assigned to one of the base bodies 10, for example the base body 10 lying on the operating side of the machine. The scroll rail 11 has a plurality, in particular at least three, preferably between ten and thirty, here for example twenty-seven, of guide rollers 23, which are each preferably rotatably mounted about an in particular vertical axis of rotation. The scroll rail 11 furthermore has an in particular vertically oriented pendulum or

Swivel axis 20, around which the scroll rail 1 1 is pivotally mounted. The pivot axis 20 can, for example, be arranged at least approximately in the center of the scroll rail 11 with respect to the transport direction T. The is therefore preferred

The entirety of the guide rollers 23 can be displaced about the pivot axis 20. The pivot axis 20 preferably forms a centrally located pivot point about which the scroll rail 11 is pivotally mounted. This particularly preferably enables compensation of an oblique cut of an incoming panel 7 or scroll panel 7.

A scroll rail 11 preferably has a guide means for guiding the

The position-changeable sensor 24.2 can be positioned manually or automatically in relation to the scroll rail 11 in such a way that it is outside the scroll when the scroll table 7 is aligned with front edge stops, in particular the contact marks 6, or in the gripper system 9 of the cylinder, in particular the printing cylinder 3 -Cuts 7.1 lies. In particular, the position of the sensor 24.2 can be determined from the format of the scroll table 7 or the dimensions of the scroll sections 7.1. The displaceable sensor 24.2 can be set manually or automatically, with in particular a fixing device being provided for fixing the positioned sensor 24.2. Positioning is preferably carried out by moving the sensor 24.2 in or against the transport direction T.

Furthermore, the scroll rail 11 can have at least or exactly two sensors 24.1, 24.2, wherein one or both of the sensors 24.2 can be designed to be displaceable. The displaceability of a sensor 24.2 can be achieved, for example, by means of a straight or linear guide. For example, a first sensor 24.1 can be assigned to the scroll rail 11 in a fixed manner and a second sensor 24.2 can be displaced and ascertained. The sensors 24.1, 24.2 are or are positioned so that it is ensured that, in particular when the gripper system 9 of the gripper system 9 closes at least one sensor 24.1, 24.2 can measure the side edge of a scroll table 7 and does not lie in a scroll section 7.1.

The measured values can also be averaged and / or trends can be taken into account. The measured values or averaged measured values can be compared, for example, as actual values with predetermined target values, tolerance limits also being able to be taken into account. If the measured value lies outside a set tolerance limit, the specifically measured panel 7 or scroll panel 7 is removed, for example in the subsequent process, and / or an optical and / or acoustic signal appears. Alternatively or additionally, a machine function, such as a machine stop, can be initiated. However, the measured values can also be logged. Based on the protocols, later differentiated processing or separation of the panels 7 or scroll panels 7 can also take place.

- A scroll table 7 is preferably placed in the feed frame. - The scroll table 7 is in contact with front edge stops, in particular the

Application marks 6 brought or typed on the gripper closure, in particular of the gripper system 9 of the printing cylinder 3.

In the case of a displaceable sensor 24.2, this is set to a position of a scroll ear between the scroll sections 7.1 of the scroll table 7.

- If there are several sensors 24.1, 24.2, 24.3, the position of the sensors 24.1, 24.2, 24.3 can be checked manually or automatically with respect to the existing scroll ears. In the event of no correspondence, at least one displaceable sensor 24.2 is set to a position of a scroll ear and this sensor 24.2 is preferably also selected at the control center.

- In the case of several fixed sensors 24.1, 24.2, 24.3, the sensor 24.1, 24.2, 24.3 is determined automatically or by the operator, which contact has a scroll ear, and this sensor 24.1, 24.2, 24.3 is accordingly also preferably selected at the control center.
