Description

Field of the invention

The present invention relates to a method for surface treatment of material plates made of foamed and / or non-foamed material having the features according to the preamble of claim 1 and a device for surface treatment of such material plates having the features according to the preamble of claim 10.

State of the art

However, the main field of application of the present invention, to which the invention is not limited, is the treatment of hard foam boards, which are used for the production of thermal barrier coatings, in particular for buildings. Such insulation boards are used due to existing energy saving regulations, especially in the construction and real estate sector and in the industry to achieve sufficient thermal insulation to save non-renewable energy sources. Optimum heat insulation can significantly reduce the heating costs and / or operating costs of a house or industrial plant. For this reason, in the past, plastic foam elements were used as insulating panels with particularly strong thicknesses of more than 100 mm for building insulation. For this purpose, especially insulating materials such as rigid polyurethane foam, expanded polystyrene foam or extruded polystyrene foam were known. Extruded material panels are usually process-limited in width and height usually limited. Thus, a maximum height of 100 mm with a plate width of 1200 mm and a height of 240 mm height with a plate width of 600 mm is common. Basically, however, other widths and heights are conceivable.

Often there is a need to produce in the production of material plates no plane-parallel plates, but instead material plates with, for example, wedge-shaped and / or curved and possibly three-dimensional course, for example for the insulation of roofs, parts of buildings or industrial plants. The production of, for example, sloping roofs is usually done so that the substrate of the material plates is constructed at an angle, for example by timber frame construction or pouring concrete with a slope. It is also customary to provide individual panels individually with corresponding bevels or provide chocks, to create slopes. For example, a material plate is moved in a transport direction and thereby machined or milled with a tool shaft such as a planner shaft so that it has a lower height at the beginning of the plate than at the end of the plate. The tool shaft is raised in accordance with the transport speed, while the material plate passes under the tool shaft. With the wedge-shaped material plates, for example, sloping ceilings are created or compensated.

From the preamble of the independent claims underlying DE 20 00 902 A1 For example, a cutting machine for cutting a multi-curved surface on a workpiece is known. The cutting device is tiltable and horizontally and vertically adjustable.

From the DE 20 2007 051 864 A1 For example, a body cutting apparatus is known as foamed polystyrene trailing insulation, wherein a heating wire is guided along guides at any angle relative to the workpiece.

From the DE 10 2008 051 864 A1 are an apparatus and a method for cutting plastic foam plates removable, in which by adjusting the inclination of the cutter and feed the supplied plastic foam plates angular blanks are possible.

Summary of the invention

Object of the present invention is to provide a method and an apparatus for surface treatment of material plates, which or the production of high-quality material plates at the same time energy-efficient process and high speed allows so that even with multiple material plates continuous transitions on the final product result.

These objects are achieved by a method and a device for surface treatment of material plates made of foamed and / or non-foamed materials with the features of the independent claims. Advantageous developments are the subject of the dependent claims and the drawings and the description. The features listed individually in the claims can be combined in a technologically meaningful way and can by explanatory facts from the description and supplemented by details from the figures, wherein further embodiments of the invention are shown.

It is proposed a method for surface treatment of material plates made of foamed and / or not foamed material, wherein at least one first material plate is fed by means of at least one conveyor in a transport direction of at least one processing station. An angle and / or a height are set dynamically between a processing element and a material plate surface.

Conveniently, an adjustment of the processing element and / or conveyor between two successive material plates to effect quickly, for example, to achieve a different inclination of the treated surface.

The feeding of the material plates via the conveyor may e.g. with vacuum bands, air bags, mangle rolls, alignment rolls, driven stop rulers, stationary or driven, slides or pushers. Also conceivable are slides and pushers or lateral guides and slats.

Advantageously, the processing element can be dynamically adjusted in height and / or its inclination. In this case, for example, after each material plate an adjustment of the processing element of the processing station and / or the conveyor can be carried out so that a material plate can be produced with an inclined surface. This can be done by editing such as Milling the surface or by separating or cutting the material plate, for example, in two parts done. A production of different material plate thicknesses in a batch is possible. Likewise, differently processed surfaces and different surface qualities of material plates can be produced in one batch. The structure is compact, so that energy-efficient work can be done and fewer components are required in the system.

As a result, several material plates can be processed consecutively, wherein each subsequent material plate can be processed so that successive material plates in the composite in the transport direction state at its interface continuously merge into one another. It is thus possible to form prefabricated elements from a plurality of material plates which can be assembled at the place of use. Preferred applications are insulation in the construction and industrial sectors.

The fact that the one or more processing elements can preferably be adjusted between the processing of two successive material plates, the hitherto required changeover times, since even with a small stock of material plates in the short term a large range of geometry can be covered in to be produced material plates. The adjustment can be highly dynamic.

This leads to a high degree of flexibility and low storage capacities in the manufacturing companies. Any thickness, and the use of a joining station following the processing station, any widths and lengths of material plates can be generated in one station but also in several stations. A reworking after the possible joining process can be avoided or at least minimized, since a high precision is ensured by the location close to the welding station positioning. This also considerably reduces possible waste by reworking and thus contributes to a resource-conserving handling of the required raw materials. At the same time, the throughput can be increased, especially in the production of four or more layers, by continuously processing the material plates and subsequently allowing several plates to be welded together in a continuous flow to form a stack of plates.

Likewise, it is possible to minimize or avoid waste and scrap on a material plate by a suitable process control. At the same time a precise and reproducible shaping of the material plates is possible.

Preferably, a first surface of the material plate can be processed in a first processing station and a second surface of the material plate can be processed in a second processing station. Likewise, if necessary, a processing of a plurality of preferably, but not necessarily, opposing surfaces in a processing station done. By the possibility of two-sided or multi-sided processing of the material plate turning stations, intermediate storage stations and the like can be saved. Preferably, after a surface treatment, in particular with one of the processing elements, the material plates can be fed directly to a welding station to the surfaces to be joined. Due to the supply in connection with the dynamic adjustment of the processing elements with a processing of the material plates above and / or below, a turning station and / or a Plattenhubstation can be saved.

In principle, a machining of the tool plates without slope is possible. This is particularly advantageous when two processing stations follow each other. An adjustment of the processing element or the processing elements can be highly dynamic in the temporal gap, when the processed in the first processing station material plate is moved to the other processing station. With particular advantage, the material plate can be processed in one processing station from one side, for example from above, and in the other processing station from another side, for example, from below. Advantageously, the conveyors of the processing stations are each designed so that they are in the different processing stations with different surfaces of the material plate in contact.

According to a favorable embodiment, a plurality of material plates can be continuously processed consecutively, wherein at least two material plates after processing may have a different average plate thickness. Preferably, the settings of the processing element and / or the conveyor during processing of a material plate remain constant.

Preferably, a plurality of material plates can be processed successively with a height offset between the front ends of the respective material plates and / or the surface thereof with an angle and / or angular offset.

Advantageously, an adjustment of an axis of the processing element and / or an axis of a conveyor synchronized to the feed rate of the material plate done. A high precision and reproducibility of the surface contour of the material plate is achievable.

In a preferred embodiment, the inclined surface of the material plate can be eroded, preferably by milling, in particular by means of a planer shaft. Preferably the planner shaft is e.g. adjustable in height by a backlash-free ball screw with a servo motor. This can be provided at both ends of the planner shaft, so that any inclination of the planner shaft as well as a height adjustment of the plunger shaft is to accomplish a total of simple and precise.

Conveniently, the inclined surface of the material plate can be produced by cutting the material plate, in particular by means of a heating element. This variant is particularly material-saving and can greatly reduce waste by waste. The heating element may preferably be a heating wire, which is adjustable in height with a servo motor. This can be provided at both ends of the heating element, so that any inclination of the heating element as well as a height adjustment of the heating element as a whole is easy and precise to accomplish.

Preferably rigid material panels can be supplied as material plates, which preferably have the same thickness before machining. Optionally, however, the material plates may also have different thicknesses. The adjustment of the processing station allow handling of different geometries of the material plates.

According to a favorable embodiment, two or more material plates can be joined after processing, in particular thermally joined, and form a plate stack. Preferably, the outer material plate in the plate stack may have an untreated surface in the processing station. It can be made time-consuming and cost-optimized and interconnected differently processed material plates. Customer-specific requirements can be reliably implemented.

According to a further aspect of the invention, a computer program product is proposed, comprising a computer-readable storage medium containing a program code, which is designed to carry out a method for surface treating material sheets of foamed and / or non-foamed material, if the program code is present on a data processing device is carried out, wherein by means of the method at least one first material plate is supplied by means of at least one conveyor in a transport direction of at least one processing station. Between a processing element and a material plate surface, an angle and / or a height between a processing element and a material plate surface are set dynamically between the passage of two material plates. The computer program product can in particular be used in a control and / or regulating unit which controls or regulates the at least one processing station.

According to a further aspect of the invention, a device for surface treatment of material plates of foamed and / or non-foamed material is proposed, in particular for carrying out the method, wherein at least one first material plate is fed by at least one conveyor in a transport direction of at least one processing station and between a processing element and a material plate surface is set at an angle and at least one obliquely inclined surface of the material plate is produced, wherein the surface in a direction transverse to the transport direction in a slope. The device comprises at least one processing station, at least one processing element and at least one conveyor. The at least one processing element and / or the at least one conveying device is adjustable in height and / or angular position relative to the material plate. In this case, at least one first material plate can be fed by means of the at least one conveying device in a transport direction of the at least one processing station. Between the passage of two material plates, an angle and / or a height between a processing element and a material plate surface are dynamically adjustable. Thus, several material plates can be successively processed so that successive material plates in the composite in the transport direction state at its interface continuously merge into one another.

The machining can be done by removing treatment, such as milling the surface, or by separating the material plate, for example, in two parts. A production of different material plate thicknesses in a batch is possible. Likewise, differently processed surfaces and different surface qualities of material plates can be produced in one batch. The structure is compact, so that energy-efficient work can be done and fewer components are required in the system.

Preferably, the device may comprise at least one sensor to detect a front and / or rear end of the material plate, wherein preferably the at least one sensor is arranged at the processing station.

Preferably, the processing element of the processing station or the processing elements of the processing stations, for example, continuously, be adjusted during the material plate run. Preferably, an adjustment takes place in the time gap between the passage of two successive material plates through the processing station.

According to a favorable embodiment of the device can be connected to the at least one processing station, a welding station for producing plate stacks of material plates. The welding station preferably allows a welding of any surfaces of material plates, in particular insulating panels. In this case, to increase the width of the longitudinal edges, to increase the length of the transverse edges and to increase the thickness or height of the insulating panels, the surfaces of the insulating panels themselves are welded together. Preferably, the material plates are positioned accurately to each other only in the welding station itself. The later the positioning takes place, the easier it is to ensure positioning, as long as it is ensured that the positioning can keep up with the throughput of the material plates.

Description of preferred embodiments

Before describing the invention in detail, it should be noted that it is not limited to the respective components of the device and the respective method steps, since these components and methods may vary. The terms used herein are intended only to describe particular embodiments and are not intended to be limiting. In addition, if singular or indefinite articles are used in the specification or claims, this also applies to the majority of these elements unless the overall context clearly makes otherwise clear. Furthermore, the same or similar elements in the various figures are numbered with the same reference numerals.

FIG. 1 shows to illustrate the invention, a schematic representation of a processing station 102 of a device 100 for surface treatment of material plates 10 of foamed and / or non-foamed material according to an embodiment of the invention. In the figure, a situation before the processing of the material plate 10 is shown.

The processing station 102 comprises at least one conveyor 40 which transports a material plate 10 at a feed speed in the transport direction 50. The transport direction 50 points in the figure perpendicular to the image plane. The conveyor 40 may be formed, for example, as a vacuum conveyor, with which the material plate 10 is sucked while it is moved in the transport direction 50.

For machining the surface 12 of the material plate 10 is a processing element 60 which extends in a direction 52 transverse to the transport direction 50, for example in shape a planner shaft 62, which mills the surface 12 of the material plate 10 over its entire width.

Furthermore, the device 100 comprises a control and / or regulating unit 110, which serves to operate the processing station 102. Preferably, the control and / or regulating unit 110 comprises a data processing device 120 in which a program for processing the material plate 10 is stored.

The processing element 60 and the conveyor 40 are formed in this embodiment, both in height and angular position relative to the material plate 10 adjustable. Serve for this purpose a drive 64 arranged on both sides of the planning shaft 62 and a drive 44 arranged on both sides of the conveying device 40. The data connection between the control and / or regulating unit 110 with the drives 64 and 44 is indicated by broken lines.

Furthermore, one or more, graphically not executed sensors for measuring the material plate 10 may be provided, which are also connected to the control and / or regulating unit 110. Preferably, sensors are provided to detect the beginning and end of the material plate 10 in the processing station 102. The material plate 10 is fed by means of the at least one conveyor 40 in the transport direction 50 of the processing station 102.

FIG. 2 shows a simplified schematic representation of the processing station 102 from FIG. 1 with inclined processing element 60. Control and / or regulating unit 110, any sensors and drives 64, 44 (s. FIG. 1 ) are not shown in this figure, but may be present. The numbers 1, 2, 3, 4 shown in circles indicate the positions of the ends of the plunger shaft 62 which forms the machining element 60.

The surface treatment of the supplied material plate 10 takes place with the inclined planner shaft 62, with which the surface 12 of the material plate 10 is obliquely milled and thus a machined, inclined surface 13 is generated. For this purpose, the planner shaft 62 is tilted by an angle α relative to the surface 12 of the material plate 10 and the surface 12 is removed. A favorable value for the angle is α = 5 °, but other values can also be set. This results in a slope of the machined surface 13, which extends in the direction 52 transverse to the transport direction 50.

FIG. 3 shows a simplified schematic representation of the processing station 102 from FIG. 1 with obliquely positioned conveyor 40. Control and / or regulating unit 110, any sensors and drives 64, 44 (s. FIG. 1 ) are not shown in this figure, but may be present. The numbers 1, 2, 3, 4 shown in circles indicate the positions of the ends of the conveyor 40, which can take these, while the surface 12 of the material plate 10 is processed by the processing element 60, preferably milled.

The surface treatment of the supplied material plate 10 takes place with the inclined planetary shaft 62, with which the surface 12 of the material plate 10 obliquely processed and, for example. is milled off and so a machined, inclined surface 13 is generated. For this purpose, the planner shaft 62 is tilted by an angle α relative to the surface 12 of the material plate 10 and the surface 12 is removed. This results in a slope of the machined surface 13, which extends in the direction 52 transverse to the transport direction 50.

FIG. 4 shows a simplified schematic representation of the processing station 102 according to an embodiment similar to in FIG. 1 , Control and / or regulating unit 110, any sensors and drives 64, 44 (s. FIG. 1 ) are not shown in this figure, but may be present. In this embodiment, the surface treatment of the material plate 10 is not carried out by removing a surface 12, but by cutting the material plate 10 with a processing element 70 in the form of a heating element 72. The heating element, such as a heating wire, cuts the material plate 10 in two parts and forms two material plates 16, 18 with inclined surfaces 17, 19.

According to the processing element 60 in the FIGS. 1 to 3 For example, the heating element 72 may also be provided with a drive on both sides. The numbers 1, 2, 3, 4 shown in circles in turn indicate the positions of the ends of the heating element 72, which can take this, while the material plate 10 is processed by the processing element 70, that is cut.

The heating element 70 is tilted at an angle α relative to the surface 12 of the material plate 10 and passes through the material plate 10, while it is moved in the transport direction 50 by the processing station 102. This results in a slope of the surface 17, 19 of the cut material plates 16, 18, which extends in the direction 52 transverse to the transport direction 50. Optionally, a tilting of the conveyor 40 is conceivable, wherein the material plate 10 is inclined and the heating wire remains horizontal. in principle It is also possible to use a curved heating wire or a curved planning shaft, for example in the form of a position-controlled articulated joint, in order to be able to produce three-dimensional shapes even more precisely.

An adjustment of the processing elements 60, 70 in the embodiments shown, if desired, take place in the period after which the processed material plate 10 leaves the processing station 102 and a new one is supplied for processing.

As a result of the dynamic adjustment of the machining elements 60, 70, different machining heights and different angles α as well as inclines running from right to left or running from left to right, as viewed in the transporting direction 50, can be achieved. In principle, bevels can also be generated which, seen in the transport direction 50, run from front to back or from back to front. Advantageously, it is possible to produce in a batch of material plates 10 in a kind of modular system.

Due to the software-bound machining, it is possible to produce inclinations on the individual material plates, which are coordinated with one another such that molds adapted to large-area roof inclinations, building shapes or industrial plants can be produced, for example with dam panels, an edge offset between material plates 10 can be eliminated and, if necessary, the individual Material plates 10 can be added systematically, for example by means of a number marking. Mistakes and rejects when installing the material plates 10 can be avoided. A documentation for the laying scheme of the material plates 10 can also be advantageously produced since the processing parameters in the control and / or regulating unit 110 (FIG. FIG. 1 ) are known. There, a corresponding documentation system may be present, from which, for example, the laying scheme of the material plates 10 can be retrieved.

In this case, the control and / or regulating unit 110 can be programmed such that individual programs and processing steps make it possible to produce a complete product from composite individual material plates 10, for example modules for producing an insulating layer of a complete flat roof or an insulating cladding of an industrial plant.

FIG. 5 shows by way of example as a sectional view a schematic representation of a composite 80 of treated material plates 30, 31, 32, 33, 34, 35 of a machined surface 13, in a continuous slope with respect to the lower surface 11 without edge offset at the lateral contact surfaces 82, 84, 86, 88, 90 between the material plates 30, 31, 32, 33, 34, 35 extends. Particularly advantageously, in the production of the material plates 30, 31, 32, 33, 34, 35, a laying scheme can be generated, which is supplied with the material plates 30, 31, 32, 33, 34, 35. These can for example be provided with a corresponding number code or the like.

FIG. 6 shows a simplified schematic representation of a device 100 in longitudinal section with two successive processing stations 102, 104, with which a material plate 10 successively from two sides, in the figure from above and below, processed. The numbers 1, 2, 3, 4 shown in circles indicate positions of the planner shafts 62, 66, which form the processing elements 60 of the two processing stations 102, 104. Control and / or regulating unit 110, any sensors and drives 64, 44 (s. FIG. 1 ) are not shown in this figure, but may be present.

The material plate 10 has seen in the transport direction 50 a front and a rear end 20, 22, wherein preferably a sensor at one or each of the processing stations 102, 104 is arranged to detect the front and rear ends 20, 22 of the material plate 10. In synchronism with the detection, the processing elements 60 arranged between the processing stations 40, 42 can be automatically adjusted with the desired heights and / or inclination angles.

In the front processing station 102, the material plate 10 lies with its lower surface 11 on the conveyor 40 and can be processed with the planner shaft 62 from above, on its surface 12. In the following processing station 104, the local conveyor 42 contacts the surface 11, so that the material plate 10 can now be processed on its previous bottom 11 with the plunger shaft 66.

For processing the material plate, the plunger shaft 62 can be moved in the first, front processing station 40 in and between the positions 1 and 2 to perform a machining of the surface 12 from above. In the second processing station 104, in which the material plate 10 is held on its upper surface 12, a machining of the surface 11 can be carried out from below, when the plunger shaft 66 in position 3 and the plunger shaft 62 in position 1. Simultaneous machining of both surfaces 11, 12 of the material plate 10 can take place when the two planner shafts 62, 66 are in positions 2 and 3. Position 4 is a rest position of the plunger shaft 66 in which it does not come to rest on the material plate 10.

The plunger shafts 62, 66 may be aligned parallel to the surfaces or inclined one or both thereof. Even with parallel alignment, a slope can be formed, in the direction of the transport direction 50, by a height adjustment of one or both plunger shafts 62, 66 synchronized with the feed rate of the material plate 10 takes place. Thus, in this case, the inclination angle α in the transport direction 50 with the tangent of the feed rate divided by the vertical speed of the relevant planetary shaft 62 and 66 results.

Subsequent to the second, rear processing station 104, or optionally further processing stations, a welding station, not shown, can follow, be joined in the material plates 10 to form a plate stack, in particular by a welding operation.

By the method, any continuous surfaces and thicknesses of insulating panels of extruded standard formats can be produced in a continuous supply of the welding partners, so the material plates 10. A subsequent cut to any geometric shapes and surfaces is possible. In this case, the limits of extrusion in the production of the material plates 10 can be taken into account, and it can be used with optimal thermal insulation values readily material plates 10. At the same time, high throughput rates are easily possible. In addition, the process can also be significantly simplified in the production of multilayer material plates 10 with more than two layers.

The device can be controlled by a computer program product according to the method. The computer program product comprises a computer-readable storage medium containing program code adapted to carry out the method for surface treating material sheets of foamed and / or non-foamed material when the program code is executed on a data processing device. At least one first material plate is fed by means of the method by means of at least one conveyor in a transport direction of at least one processing station. Between a processing element and a material plate surface, an angle and / or a height between a processing element and a material plate surface are set dynamically between the passage of two material plates. The computer program product can in particular be used in a control and / or regulating unit which controls or regulates the at least one processing station.
