The invention is based on the objective of creating an alternative substrate processing machine for printing and/or coating a substrate in the form of a panel with an alternative installation and method for operating a substrate processing machine for printing. and/or lacquer a substrate in the form of a panel. In particular, improved lateral registration and/or reduced set-up time must be achieved.

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 the independent method claim. Advantageous configurations are apparent from the dependent claims, the description and the drawings.

The invention has the advantage that an alternative substrate processing machine for printing and/or coating a substrate in the form of a panel is created with an alternative installation and method for operating a substrate processing machine for printing. and/or lacquer a substrate in the form of a panel. In particular, improved lateral registration is achieved and reduced setup time is achieved, respectively. A corresponding substrate processing machine prints and/or coats a substrate in the form of a panel, in particular sheet metal panels or scroll panels.

In particular, in the case of a panel-shaped substrate processing machine, for example a panel or displacement panel processing machine, the panels or displacement panels are oriented, for example, against a feed frame, preferably during run at production speed, and are fed into a machining gap, eg a printing gap. In this regard, the panels or scroll panels are positioned in particular by a rocking side marker and a rocking side push. Preferably, a substrate abutting against leading edge stops is oriented by a movement of the lateral marking and the lateral thrust towards one another, the lateral thrust being carried out in particular with spring resiliency and the orientation thus taking place against the lateral marking .

A movement of the lateral thrust and/or of the lateral mark takes place via an individual electronically controlled drive, for example an electric motor or a servomotor. This individual drive, for example a servo motor, carries out a lateral format adjustment and can also carry out an oscillating movement transverse to the transport direction.

A movement transverse to the conveying direction, in particular an oscillation stroke, can be set and/or executed independently of one another by means of individual drives. For example, a stroke on the mark side can therefore be set by 2mm (millimeters) instead of the usual 6mm. Correspondingly, the stroke on the thrust side can also be set to a different or the same trajectory, for example 4 mm or also 2 mm, for example, in addition to a preselectable elastic deflection trajectory, for example.

The lateral push and the lateral marking, which are actuated in particular by the individual drives in an oscillating manner, preferentially orient the substrates or panels, which have been previously oriented against leading edge stops, for example, at production speed with a register. accurate lateral while the machine is running. For this, lateral guidance systems or lateral guidance equipment move together on both sides. The lateral edge of the panel is oriented against the lateral mark and the lateral thrust is elastically deflected to compensate for possible tolerances. In the innermost position, the lateral mark preferably has the position corresponding to the nominal width of the current half of the panel. Preferably, the lateral thrust is associated with an elastic trajectory X, which can be set, for example, on the control console of the machine. The elastic deflection path X can be, for example, between 1 mm and 4 mm. Therefore, in the innermost position, the lateral thrust is preferably at the position corresponding to the nominal width of the current half-panel minus the adjusted spring path X. This means that the lateral push at the innermost position is further into the substrate or panel format by X amount. If a panel is now placed in a feed frame, for example, and the lateral push is tilted toward the innermost position, the lateral thrust is elastically deflected along a path X.

Advantageously, the lateral guidance systems or lateral guidance equipment are actuated simultaneously or synchronously by the individual drives. Compared to side thrusts and side marks, which are respectively driven by a mechanical cam disc, the movement transverse to the conveying direction can be adjusted, and thus executed, independently. In this way, the swinging strokes in particular can be made variable. This makes it easy to reduce the stroke on the mark side from 6mm to 2mm. It is just as easy to reduce the stroke on the thrust side from the usual 6 mm to the sum of the elastic deflection path X plus the preferably adjustable 2 mm. This makes it particularly easy to adjust the respective strokes and/or simply interchange the mark side and the thrust side.

The impact velocity of the lateral guidance systems or lateral guidance equipment against the lateral edge is also minimized by the individually achievable minimum necessary strokes. As a result, impact velocities are also significantly reduced due to reduced strokes. As a result, there is less disturbance to the side edges, leading to better registration. Due to the reduced runs in the marking side and operational side, there are in particular lower impact velocities on both sides. At the same time, only lower lateral thrust forces are advantageously required. In the case of panels, for example, this means that they buckle less. Due to the reduced disturbance in installation, higher speeds can also be achieved and/or better lateral registration can be achieved. In addition, a reduction in preparation time can be achieved. For example, only one input on the control console is required to change the side of the mark, thereby reducing manual preparatory work on the machine.

Depending on the nature of the substrate or the type of panel to be processed, corresponding lateral guiding equipment is used in the installation of the machine. For normal panels, in particular normal veneers, individual roller equipment can be used, for example an orientation roller. Slide rails, which in particular have several rollers arranged one after the other, are used for slide panels, in particular slide sheets. However, using a scroll rail makes sense for both scroll panels and thin panels from, say, about 0.18mm. Especially in the case of thin panels, there is a high probability that the panel will bulge in the middle when using a single roller. The cause is the lateral force introduced punctually. In this case, the offset rail is best, where the lateral thrust force is introduced over a greater extent and where the panel tends to buckle less, which would result in poor lateral registration. When a sliding panel is used, the individual roller sets in the installation are preferably replaced by sliding rails, in particular on both sides.

The orientation of the panels or displacement panels in the machine installation against individual roller equipment used or against used displacement rails is preferably carried out at full production speed by means of the oscillating movement in particular of the lateral thrust and the marking lateral, which is implemented by means of the two individual roller units or the two travel rails. Preferably, each panel or sliding panel is oriented laterally by a simultaneous movement of the individual roller units or the sliding rails towards each other, in particular against the established marking side. The opposite thrust side is elastically deflected accordingly to avoid damage or to compensate for tolerances. For example, a base body that receives the individual roller unit or the slide rail on the push side can have a corresponding spring.

For at least one and preferably for both lateral guidance devices, sensors can in each case be provided which measure the position of a respective lateral edge. However, it is only measured or evaluated on the brand side. For example, the mark side can be set on a control console of the machine, ie in particular the operating side or the drive side of the machine can be selected as the mark side. For example, a sensor that measures in particular in analogue form can be provided, which is permanently or repositionably attached to the respective lateral guidance device and can measure the position of the lateral edge. In particular, at least on the marking side, at least one preferably optical sensor of a lateral guidance device is used, in particular a travel rail, the sensor preferably being arranged to be displaceable, in particular in the direction of transport and against the same and, therefore, being able to fit a slider tab of a slider panel. Preferably, one or more sensors of a slide rail participate in the pivoting movement of the individual ball bearings.

With particular preference, a measurement is carried out in the case of panels or displacement panels facing against the front edge, in particular in the case of a clamp closure, preferably by means of a clamp system, for example a cylinder. For example, one or one of several sensors of a sliding rail used can be designed to be slidable in order to ensure a measurement on a sliding lug, ie outside the sliding notches of a sliding panel. In addition, a judging equipment connected to the respective sensor of the lateral guidance equipment used on the mark side can judge whether the panel or the displacement panel has been fed correctly. In this respect, an incorrectly oriented panel or scroll panel can be reliably detected during the current process.

The invention will be explained below by way of example. In this regard, the corresponding drawings show the following schematically:

Figure 1 shows an installation 1 of a machine for processing substrates or material in the form of a panel, in particular a printing and/or coating machine. In the machine, for example, the panels 7, in particular the sheet metal panels 7, are transported by one or more conveyor units 2 along a transport path in a transport direction T, in which they are machined by one or more machining modules or processing units on at least one of their sides, for example, are printed and/or lacquered. The transport of the substrate, in particular the panels 7, in this case preferably takes place without nesting, that is to say individually or with substrates, in particular the panels 7, spaced apart from one another. In order to ensure correct registration machining with respect to longitudinal registration, a cylinder can be provided at at least one point in the conveying path, preferably with leading edge orientation means, preferably leading edge stops, for correct registration orientation. of the panels 7 that arrive on the transport route, in particular by means of a conveyor equipment 2 arranged upstream of a printing cylinder 3 in the installation 1.

Through the interaction of the conveying equipment 2 for transporting the panels 7 with leading edge orientation means, preferably stops, of a cylinder, in particular with positioning marks 6 of a printing cylinder 3, the panels 7 can be positioned with a register correct and orientate correctly in case of oblique position. For this purpose, the conveying unit 2 arranged directly upstream of the cylinder, in particular of the impression cylinder 3, is preferably operated at least temporarily at a feed or transport speed greater than the peripheral speed of the cylinder, in particular of the impression cylinder. 3. Due to this at least temporarily higher feed rate, a leading edge of the panels 7 is pressed against at least one stop surface of the leading edge stops, in particular against the positioning marks 6.

The conveyor equipment 2 comprises at least one means of transporting the panels 7, for example a circulating means or a circulating and transporting means of transporting the panels 7. For example, it comprises a belt system with one or more shaped circulating means, for example, as circulating belts, on which the panels 7 are transported in the transport direction T by dragging with a stop arranged on the belt or a means of traction different from it, equally circulating, and that acts against it. the rear end of the panel 7, for example the rear thrust 8, or by force dragging (friction) with the belt system solely by its own weight or supported by friction-increasing measures, for example by means that increase supporting force and therefore friction, in particular by negative pressure or a magnetic force, for example from a magnet, in particular an electromagnet. Preferably, the effect of the medium is variable and/or can be selectively turned on and off.

The conveyor device 2 arranged upstream of the cylinder, in particular the impression cylinder 3, can preferably be configured as at least one circulating belt with a belt system having a rear thrust 8. In addition, suction and/or suction devices can be provided. guiding surfaces. In order to avoid the deformation of the panels 7 due to the different speeds after the initial contact with the stop surfaces, the conveyor equipment 2 can present means that limit the forces acting on the panel 7 for advancement. These feed force limiting means can be implemented fundamentally in different ways, depending on the design of the conveying means. In particular, the rear pusher 8 can be spring-loaded.

The panel 7 fed by the conveyor equipment 2 to the cylinder, in particular to the printing cylinder 3, oriented against the leading edge stops, in particular the positioning marks 6, is gripped in particular by a gripper system 9 and is further moved in the conveying direction T. The panel 7 runs through the machine, in particular from plant 1 to a discharge outlet, in particular in a single rectilinear conveying direction T. At the discharge exit, the panel 7 can be deposited on a pile, for example. The panel 7 is fed in the machine to a machining module, for example to at least one printing unit and/or at least one lacquering unit, in which the panel 7 is printed or lacquered by at least one side. The machining module or machining unit can be a printing unit, for example, which can have a blanket cylinder 4 and a plate cylinder 5, in addition to the printing cylinder 3. In particular, the plate cylinder 5 can be associated with a inking unit or inking and dampening unit, which inks a printing plate mounted on the plate cylinder 5 in a manner corresponding to the printing ink used. When the plate cylinder 5 rolls over the blanket cylinder 4, the printing ink is transferred to the blanket cylinder 4, which in particular is covered with a blanket, in accordance with the drawing. A printing gap is formed between the blanket cylinder 4 and the printing cylinder 3, through which the panel 7 to be printed is conveyed. The printing ink is transferred from the blanket cylinder 4 to the substrate or panel 7 in the printing gap.

The substrate to be processed, in particular a panel 7, can in principle also comprise paper material, for example a thicker sheet of paper or cardboard, for example up to at least 1 mm. of 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 metal panels 7, in particular sheet metal panels 7. The panels 7 in the preferred sense here are characterized, for example, in contrast to thin sheets of paper, for example by having, with respect to their longitudinal extension running in the transport direction T, a significantly higher bending stiffness and/or a higher basis weight, for example at least 1 kg/m2, in particular 1 to 3 kg/m2, than the thin sheets of paper. They are characterized, for example, in that they are not wound on the curved surfaces of rollers or rotating transport rollers, but rather are conveyed through said rollers and rollers, possibly with a slight bending and/or optionally with a negligible linkage, for example, for less than 20°, only in an essentially straight line. Panels 7 in this sense, in addition to the preferred embodiment as metal panels 7, for example sheet metal panels 7, for example made of tin or aluminum sheet, also consider panels 7 made of more sensitive material, such as panels 7 made of plastic, wood, a composite material or cardboard, in particular provided that they are designed, for example in the abovementioned sense, to be rigid in bending.

For example, Figure 2 shows a special panel 7, called a scroll panel 7. The scroll panel 7 has at least one, but preferably two, irregular side edges or side surfaces. This means that a side surface of the scroll panel 7 deviates from a particular vertical spatial plane. In this case, the two lateral edges each have offset notches 7.1. In addition to being oriented at the leading edge, such scroll panels 7 must also be oriented laterally, for example against leading edge stops, such as positioning marks 6, in order to be able to be processed, in particular printed and/or lacquered, with accurate registration. The dimensions shown are for example only and vary depending on the scroll panels 7 to be processed. This means that the offset notches 7.1 are in each case at different locations as soon as the front edges of the different offset panels 7 come into contact with the front edge stops, such as the front marks 6, with their front edges. The sections of material, which lie between the offset notches 7.1 and represent the side edges of the offset panel 7, are also called offset lugs.

Figure 3 shows an installation 1 for a panel-shaped substrate processing machine, for example as described above. A conveyor unit 2 is provided for transporting the panels, which has a feeding frame. Here, the feed frame is made in two parts, for example, each part being attached to crossbars, for example, so that it can change position in particular transversely to the conveying direction T. Each part of the feed frame has, in in particular, circulating belts or suction belts, preferably with rear pushers 8 in particular spring-loaded, which are not shown. One or both partial frames can be repositioned transversely to the transport direction T to adjust the format. The feed frame has a lateral guide for the substrate in the form of a panel, in particular the panels 7, on at least one and preferably on both sides. In particular, the two parts of the feed frame each have base bodies 10 opposite one another, to which lateral guide devices can preferably be associated interchangeably. A respective base body 10 is adjusted to the respective format with the respective part of the feed frame transverse to the conveying direction T. The base bodies 10 can be constructed identically, for example with mirror symmetry.

An individual drive, in particular in each case a servomotor 12, 13, is associated with both the drive side and the operating side of the machine. A respective individual drive, in particular a servomotor 12, 13, can act on a base body 10, for example. For example, the base body 10 can in each case be associated with a lateral guide device, which can be repositioned transversely to the conveying direction T by means of individual drives, in particular a servomotor 12, 13. In this case, a drive Individual drives, in particular a servomotor 12, 13, can preferably carry out both adjustment of the lateral guidance equipment to the current format and a rocking movement for orienting the panels 7. In addition, individual drives, in particular servomotors 12, 13, can also adjust other elements to the format. For example, a respective part of the feed frame and/or another side guide can be repositioned by the respective individual drive, in particular the servomotor 12, 13. For example, a side guide rail can be repositioned by the respective drive individual, in particular the servo motor 12, 13, and therefore fit the format. These elements, in particular the guide rail, can be temporarily coupled to the individual drive, in particular to the servomotor 12, 13, for format adjustment. For example, a guide rail that can be adjusted to the format by individual drive, in particular the actuator 12, 13, can be configured as a conically tapering lateral guide rail 14 for lateral preorientation.

A base body 10, which is associated with the respective part of the feed frame and configured to accommodate a respective lateral guide device, is connected to a single drive, in particular a servomotor 12, 13, in such a way that this base body 10 , which is attached in particular to guide means, such as crossbars, can be changed in position transversely to the direction of transport T. A single drive, in particular a servomotor 12, 13, can preferentially transmit a movement to the lateral guide device, for example to a base body 10 that carries a lateral guide unit, through a threaded spindle. Alternatively, the individual drive can be configured as a linear drive or a linear motor.

The respective base body 10 can be positioned transversely to the conveying direction T by individual drive, in particular the servomotor 12, 13, in particular together with the feed frame part, for format adjustment. A base body 10 can in this connection be associated with a spring that limits the oscillation stroke and correspondingly limits the stroke path when used on the thrust side. The oscillating movement of the lateral guide devices preferably takes place in opposition to phase, ie the lateral guide devices move towards and away from each other at the same time. Preferably, the oscillating movement is synchronized with the movement of the panel in such a way that each panel 7 or displacement panel 7 is touched at least or exactly once by the lateral guidance equipment and, therefore, is guide. The strokes of the oscillating movements can also be designed, in this connection, to be adjustable or variable independently of one another. In this connection, the strokes or movements can also still be changed or adapted while the machine is running.

A lateral guide device can be set as a lateral mark or as a lateral thrust by means of a control device, for example the machine control, which is connected to both individual drives, in particular to both servomotors 12, 13. The Control equipment, in particular the machine control, preferably controls both individual drives, in particular the servomotors 12, 13, so that the marking sides can be switched quickly without retrofitting. The values necessary for the adjustment of the installation 1 can be taken from existing programs or entered via input means, for example, on the control console of the machine. As an improvement, it is also possible to select or adjust an elastic path of a spring, in particular for a thrust side, by means of actuators, for example from the operating console.

A base body 10 can optionally be associated, for example, with lateral guiding equipment that has either a single roller or a plurality or multiplicity of rollers for laterally guiding the panel-shaped substrate, in particular the panels 7. In particular In this case, both base bodies 10 are used either in each case with an individual roller unit 25, preferably for guiding panels 7 with flat side edges or flat side surfaces, or in each case lateral guide units with a plurality or multiplicity of rollers. Lateral guide 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 to guide panels 7 that are very thin and/or do not have flat side edges or flat side surfaces. In particular, lateral guiding equipment with a plurality of rollers is used to guide sliding panels 7 with lateral sliding notches 7.1.

4 shows a lateral guide device configured as a slide rail 11, which is associated with one of the base bodies 10, for example the base body 10 which is located on the operating side of the machine. The slide rail 11 has several, in particular at least three, preferably between ten and thirty, in this case for example twenty-seven, guide rollers 23, each of which is preferably rotatably mounted around a particular axis of rotation. vertical. The travel rail 11 also has a vertically oriented pendulum or swivel axis 20 around which the travel rail 11 is pivotally mounted. The pivot axis 20 can be arranged, for example, at least approximately in the center of the travel rail 11 with respect to the transport direction T. All of the guide rollers 23 are preferably mounted so that they can be repositioned around of the pivot axis 20. In this connection, the pivot axis 20 preferably forms a pivot point which sits in the center, around which the slide rail 11 is mounted pendularly. This makes it possible with particular preference to balance an oblique cut of an incoming panel 7 or sliding panel 7.

The sliding rail 11 preferably has a guide means for guiding the undersides of the substrates, in particular a lower sliding plate 21 for guiding the panels 7 or sliding panels 7 on their underside. More preferably, the sliding rail 11 has a guide means for guiding the upper faces of the substrates, in particular an upper sliding plate 22 for guiding the panels 7 or sliding panels 7 on their upper face. Between the lower slide plate 21 and the upper slide plate 22 are arranged rotatably mounted guide rollers 23 for guiding the side surfaces of the substrates, in particular the side surfaces of the slide panels or slide lugs.

Figure 5 shows a slide rail 11 with at least one repositionable, in particular shiftable, sensor 24.2 for detecting a side edge or a side surface while guiding the substrate, in particular a panel 7 or a slide panel. 7. The sensor 24.2 is preferably arranged on the slide rail 11 in such a way that it pivots together with the slide rail 11 around the pivot axis 20. The variable position sensor 24.2 can be manually or automatically positioned relative to the slide rail. displacement 11 in such a way that, when the displacement panel 7 is oriented against the leading edge stops, in particular the positioning marks 6, or is in the clamping system 9 of the cylinder, in particular the printing cylinder 3, it is located outside the displacement notches 7.1. In particular, the position of the sensor 24.2 can be determined from the format of the displacement panel 7 or the dimensions of the displacement notches 7.1. The repositionable sensor 24.2 can be adjusted manually or automatically, in particular a fixing device being provided for fixing the positioned sensor 24.2. Positioning preferably takes place by repositioning the sensor 24.2 in or against the conveying direction T.

In addition, the travel rail 11 can have at least or exactly two sensors 24.1, 24.2, it being possible for at least one or the sensors 24.2 to be configured in such a way that they can be changed in position. The possibility of changing the position of a sensor 24.2 can be achieved, for example, by means of a straight or linear guide that can preferably be set. For example, a first sensor 24.1 can be associated to the travel rail 11 in a fixed manner and a second sensor 24.2 can be associated in such a way that it can be changed in position and locked.

The sensors 24.1, 24.2 are or are positioned in such a way as to ensure that, in particular with the gripper closure of the gripper system 9 of the printing cylinder 3, at least one sensor 24.1, 24.2 can measure the edge side of a scroll panel 7 and is not located in a scroll notch 7.1. The sensor(s) 24.1, 24.2 are preferably designed as optical sensors, preferably as light barriers, in particular as forked light barriers.

The sensor or sensors 24.1, 24.2 are preferably connected to an evaluation device that evaluates the measured values determined by one or more sensors 24.1, 24.2, in particular on the traction side. In this connection, the measured values can also be averaged or trends can be taken into account. The measured values or averaged measured values can be compared, for example, as actual values, with specified theoretical values, and tolerance limits can also be taken into account. If the measured value lies outside a set tolerance limit, the panel 7, in particular the displacement panel 7, actually measured is ejected, 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 also be initiated. However, measurement values can also be recorded. Based on the records, further differentiated machining or sorting of the panels 7 or displacement panels 7 can also take place.

6 shows a travel rail 11 with stationary sensors 24, in this particular case three stationary sensors 24.1, 24.2, 24.3 being provided. The sensors 24.1, 24.2, 24.3 are arranged on the slide rail 11 in such a way that, in particular with the gripper closure of the gripper system 9 of the printing cylinder 3, at least one of the sensors 24.1, 24.2, 24.3 can measuring the side edge or the side surface of a scroll panel 7 and does not lie in a scroll notch 7.1. By means of the three sensors 24.1, 24.2, 24.3 a wide range of possible embodiments of displacement panels 7 can be covered in this respect. The evaluation can be carried out as before by means of an evaluation device, which can also be connect to the machine control or be integrated into it. The use of sliding rails 11 for panels 7 or thin sliding panels 7 is recommended.

FIG. 7 shows a lateral guide device that can be associated with a base body 10 as an alternative and that is designed in particular as an individual roller device 25. The individual roller device 25 can be associated with the base body 10 interchangeably and, In addition to a lower sliding plate 21, it preferably comprises an upper compression roller 26, which guides the side region of a panel 7 against the lower sliding plate 21. The individual roller unit 25 also has one or only one guide roller 23, which is rotatably mounted about a vertical axis of rotation and guiding the lateral edge of the panel or the lateral surface of the panel. The individual roller equipment 25 is used in particular in the case of rectangular panels 7.

8 shows a single roller unit 25 with a sensor 24.1, which is designed, for example, as an optical sensor, preferably a light barrier, in particular a forked light barrier. The sensor 24.1 preferably has the same connections as a sensor 24.1, 24.2, 24.3 of a travel rail 11, which allows easier association with the evaluation unit. The connection of a sensor 24.1, 24.2, 24.3 with the evaluation device can also take place automatically by inserting the respective lateral guide device into the base body 10, for example via a plug-in contact. Depending on the substrate to be processed, suitable side guiding equipment is preferably used in the machine installation.

Regarding the mode of action: The individual drives, in particular the servomotors 12, 13, associated with the lateral guidance equipment, in particular the slide rails 11 or individual roller equipment 25, adjust one or both to the current format. of the substrate, in particular the width of a panel 7 or scroll panel 7 to be processed. In this connection, other coupled elements, such as one or two conically tapering side guide rails 14, can also be adapted to the format.

The oscillating movement of the lateral guide devices, in particular the slide rails 11 or the individual roller devices 25, then takes place transversely to the transport direction T by means of a respective individual drive, in particular a servomotor 12, 13. at least once for each substrate to be processed, in particular panel 7 or sliding panel 7. The oscillating stroke of side guiding equipment, in particular sliding rails 11 or single roller equipment 25, is In this case, it is carried out mechanically independently of one another or in a differentiated way, that is to say individually, by means of the individual drives, in particular the servomotors 12, 13.

Due to the independently mutually adjustable, in particular shortened, strokes of the individual drives, in particular the servomotors 12, 13, the marking and thrust impact speeds are significantly reduced. The result of this is that there is less disturbance on the panel 7 or scroll panel 7, which in turn leads to better lateral registration. A conversion on the mark side is possible, in particular, by changing the program of the individual drives, in particular of the servomotors 12, 13, simply, quickly and user-friendly.
