Description

The invention relates to a large-plate production apparatus for producing at least one large-area composite panel for use as mounting panels preferably in vehicle construction, in particular for panel vans, and a method for manufacturing composite panels. Such composite panels, which are also referred to as sandwich panels, can be used in container, vehicle and bridge construction as well as for other applications, such as in shipbuilding for walls and decks. They usually consist of two substantially parallel cover layers and an intermediate layer extending between the two cover layers. An advantage of such composited composite panels is that they have a low mass and can be structurally designed according to the requirements in terms of their properties such as strength, thermal insulation and fire protection. A preferred field of use of the large-area composite panels is vehicle construction. For example, the composite panels are used for the walls of ambulances, refrigerated transporters, etc., preferably in special vehicle construction. Particular demands are placed on the structures of such vehicles, since, for example, in the case of deployment as an ambulance structure, in the event of a rollover of the vehicle, they must enable the occupants to survive. In addition to the requirement for high stability and strength of the composite panels they must have the lowest possible weight in order to achieve a vehicle body with the lowest possible weight. On the one hand, a low weight reduces the operating costs for the motor vehicle and, on the other hand, it allows a higher payload of special accessories or persons. For the production of such composite panels discontinuous and continuous processes are known from the prior art.

DE 199 42 922 A1 describes a continuous process for producing a sandwich panel. Between two substantially parallel cover layers, an intermediate layer provided with recesses is introduced. A continuous process is achieved by applying an adhesive to a first cover layer and adhering the first cover layer to the intermediate layer. Subsequently, will On the side opposite the first cover layer side of the intermediate layer and on the recesses in the intermediate layer, the second cover layer is adhered continuously.

A discontinuous process of sandwich panels made of steel is described in DE 197 27 349 A1. To produce the sandwich panels, web plates are placed in a fixing frame and positioned. Thereafter, the first outer sheet is placed on the web plates and welded to the web plates. After welding the web strip to the outer panel, the section is turned and placed a second outer panel on the webs and positioned. Then the clocking and positioning takes place in the welding station for welding the individual seams. The disadvantage here is the very high space requirement for positioning and moving the panels in relation to the hall area as well as the hall height.

A composite panel for use as body panels in vehicle construction is described in DE 101 10 996 B4. The cover layers of the wall elements are glued to a hard foam core layer. Here, the bonding of the components of the large-area composite panels is usually done on table surfaces, sometimes working with several juxtaposed table surfaces, on the one hand to handle the composite panels and add and process according to the individual manufacturing steps and on the other hand to the processing times, such as in particular a dry season Klebers, to take account.

A disadvantage of the known from the prior art Großplattenherstellvorrichtun- gene and the method is the high space requirement, which requires a corresponding table surface for each production step for each composite sheet to be produced. It has also proved to be disadvantageous that for the manufacture and joining of the composite panels the users work on the table surface due to their size and thus the danger of a fall of the user from the table surface exists. In addition to the high space requirement, the handling costs for the partially joined and, for example, for drying to be deposited composite panels play a major role and thus increase the cost of the composite material plate. Finally, when handling the composite panels there is also the risk that the composite panels may be damaged. Thus, the handling of the composite panels presents a production risk. The object of the present invention is to provide a large-plate-making apparatus, a method and a fabrication assembly for producing a composite panel which overcomes the known disadvantages, reduces space requirements, provides high production reliability and productivity as well as low-cost production.

The object is achieved by means of a device according to claim 1, a method according to claim 31 and a factory assembly according to claim 41. Further advantageous embodiments can be found in the respective subclaims. However, the individual features in the claims are not limited to these, but may be combined with other features of the following description as well as other dependent claims to further embodiments.

There is provided a large plate making apparatus for producing large area composite panels for use as building panels, particularly panel car panels, provided with a table surface for disposing at least one layer of composite panel and means for fixing one or more layers of the composites on the table surface, the table surface being movable is formed, so that the fixed position on the table surface, preferably a multi-layer composite material plate, from a position for loading and / or fixing in a further position, preferably for curing and / or heating can be brought. Preferably, but without limitation, the large plate making apparatus of the invention relates to the construction of large area composite panels used in commercial vehicle construction. Thus, the composite panels are used, for example, for walls of ambulances, refrigerated trucks, fire trucks, etc., preferably in special vehicles. With the large plate manufacturing device also side, roof, floor and end surfaces can be made, for example, at the same time. The composite panels can be used, for example, in container construction, for deployable residential or commercial containers, for protective containers, as shelters or for other superstructures. Also, use in the applications described above in the prior art is possible. By forming a movable table surface in the large plate manufacturing device, the possibility is now created to reduce the space required for the production of a composite material plate. In addition, the reliability of production is increased, since the composite plate remains temporarily stored on the table top, preferably for curing and / or heating remains on the table surface. There is no damage during handling or transport. In addition, the manufacturing cost is reduced by reducing the handling cost of moving the composite plate to a curing and / or heating position. Another advantage arises when the table surface is at least partially retractable. For example, with a retractable table surface that is recessed into a hall floor and the table surface is level with the hall floor, there is no longer the danger that a user of the table surface may fall off the table surface when placing parts of the composite plate.

In a first embodiment of the invention, the table surface is rotatably mounted on the large plate manufacturing apparatus. Rotatable here means that the table surface by means of a rotational movement in the large plate manufacturing device from a position in which at least one layer of the composite material plate has been arranged on the table surface moves in a further position, for example, for curing and / or heating of the composite material plate. The large plate manufacturing device is arranged, for example, stationary in a manufacturing hall, for example, panel van panels. The large plate manufacturing device forms in the manufacturing process for the production of special vehicles, such as ambulances, the manufacturing step in which the panel van panels, such as the sidewalls of an ambulance, are produced. After production of the composite panels, the body panels produced by means of a screw with Eckprofilen form a structure in the form of a van. Due to the rotatable arrangement of the table top in the large plate manufacturing device, on the one hand, the space requirement in the production hall is substantially reduced and at the same time facilitates the operation of the large plate manufacturing device, as a user or operator of the table surface can serve the table surface, for example, by a stationary control panel or console. For example, the table surface rotates about an axis in the large plate manufacturing device, so that the table surface moves over a movement path that is to be described essentially as a circular path.

A further advantage is achieved if at least one further table surface for mounting at least one further table surface in the large plate manufacturing device is fixed and that a table surface acts as an active table surface in which the at least one layer of the composite plate is arranged, machined and fixable and another Table surface acts as a passive table surface, preferably as a passive table surface on which the at least one fixed position aushärt- and / or can be heated. The arrangement of at least two table surfaces in the large plate production device makes it possible not only to reduce the time required for arranging, processing or fixing composite plates on a table surface, but it is also possible to apply a layer of composite material to a workstation add, arrange NEN and / or fix and at the same time to position a fixed on another table surface composite plate, for example, interim storage, preferably curing and / or to heat. While at least one layer of the composite material plate is arranged, processed or fixed in a first active table surface, another table surface may act as a passive table surface, wherein the passive table surface holds, for example, a joined and fixed position of a composite plate in a hardening and / or heating position , This also has an advantage because in the large plate manufacturing device large-area composite panels are produced, which can be made on the table surfaces mounting panels, for example, in dimensions of up to 15 mx 3 m. Thus, using the large plate making apparatus, it is possible to dispense with a further curing and / or heating location of a composite plate in the manufacturing hall, which, in addition to the logistical advantages, leads to a reduction in handling costs and an improvement in production safety since they are once placed on the table top Composite plates for curing and / or heating no longer have to be transported away from this. A further advantage also results from the fact that the aid of the always identical position of the active table surface can always be used to supply or store an auxiliary device, such as adhesives or tools, and composite plate components to a fixed position, namely the active table surface position.

There may be more than two table surfaces in the large plate making apparatus. In this case, two, three, four, five, six or more table surfaces can be integrated into the large plate production device. In this case, if the number of composite plates to be arranged on the table surfaces is selected such that the assembly, processing and fixing time of the composite plates on the active table surface is the same as a curing and / or heating time for a composite material plate to be produced a quasi-continuous composite plate production achievable. If, for example, the large plate production device is equipped with four table surfaces, then the time for equipping, processing and fixing all four table surfaces can correspond exactly to the time required for the first populated table surface to heat and / or cure the composite plate. After arranging, processing and fixing all four table surfaces then arranged on the first populated table surface composite plate of the large plate manufacturing device can be removed again. With the large plate manufacturing device, a time-optimized work and consequently an economically advantageous and advantageous working is possible. According to a preferred embodiment of the invention, the table surfaces are attached to a rotary module of the large plate manufacturing device. In this case, the rotation module can be sunk into the hall floor in such a way that the active table surface substantially corresponds to the hall floor, so that the active table surface can easily be committed by a user of the large plate production device. It is possible, the active table surface at a level of the hall floor or slightly offset from sunk in the hall floor to order, the user of the active table surface is easily possible to commit the active table surface with the active table surface to be populated composite plate elements. Due to the countersunk arrangement of the active table surface, the advantage is achieved that composite material plates which consist of many elements and in particular consist of smaller elements can easily be arranged on the active table surface. Another advantage that results from this is that, unlike conventional tables on which users work in part on the active table surface, users are not deceived by carelessness during, for example, arranging composite panel elements off the table top can fall. The arrangement of an active table surface on a level of the hall floor thus reduces the risk of accidents and improves the safety at the apparatus for large plate production. The rotation space required for the rotation for the active or further table surface is closed according to another embodiment of the invention, wherein the movement area enclosing the active table surface is at least partially closed by means of a pivotable bottom surface, wherein the bottom surface forms a walkable for a user of the active table surface workspace. The pivoting floor surfaces close off the space between the active table surface and an indoor floor surrounding the active table surface. It is essential here that the pivotable bottom surfaces release the rotation space for the rotation module. In addition to a floor pivoting in of the floor surface, it is possible in a preferred embodiment for the pivotable floor surface to pivot in a position pivoted out of a position in one plane with the active table surface, at least part of a safety device, in particular a walk-over protection for the active table surface, forms. Due to the essentially a 90 ° angle with the hall floor forming floor surface, it is not immediately possible for a user of the large plate manufacturing device to get on the active table surface, since the user would first have to overcome the upright floor surface. Thus, as part of the large plate making apparatus, the bottom surface forms a walk-in working area for the user and, on the other hand, a means for increasing occupational safety. In addition, it is also it is possible to design the safety device of the large plate production device with light barriers and / or light grids, wherein the light barriers and / or light grids prevent an inspection of the rotation space. It is also possible here to inspect the rotation space of the rotation module by means of the pivotable floor surfaces and / or light barriers and / or light grids and / or with acoustic and / or visual warning devices and / or a safety device and / or motion detectors and / or infrared or ultrasound sensors secure.

As it has been found advantageous that the at least two tabletops are mounted on or on a common carrier. By attaching two table surfaces to a support, it is possible to use the large plate manufacturing device to save space. The advantage can be increased by the fact that the carrier is a rotation module, so that the one table surface in an active processing position and the other table surface in a passive Aushärt- and / or heating position is pivotable. By pivoting the space required is further reduced, since the large plate manufacturing device is locatable and thus occupies only the footprint of a table surface. Preferably, a polygonal rotary module is used, which has at least three table surfaces. For example, this will be explained in more detail below with reference to four table surfaces.

In one embodiment, for example, four table surfaces are attached to the rotary module and the carrier is in the form of a polygonal, here quadrangular tube, wherein on each side of the quadrangular tube, a table surface is fixed, so that a square tube formed from the table surfaces is formed. It is advantageous to equip the rotation module with four identical, for example rectangular, table surfaces, as a result, a quadrangular shape of the rotary module can be achieved and an axis of rotation for the rotary module can be placed in the center or the center line of the quadrangular rotary module, so that a symmetrical load distribution is achievable for a drive and a storage of the rotary module in the large plate production device. This of course also applies to a provided with three table surfaces rotation module, which then has a triangular cross-sectional shape as well as for any other number of table surfaces to form a rotary module, wherein a substantially running through a center of gravity of the rotary module axis of rotation facilitates a drive of the rotary module. The table surfaces rotate on the rotation module preferably about its longitudinal axis. The table surfaces can also have different sizes. They may, for example, be subdividable according to an embodiment. For example, a table surface with associated fixation can be so converted. be prepared that different sized composite panels can be produced. For example, a table surface can be divided into different sections, be adaptable in terms of their length and / or width recording. Among other things, to reduce weight, it is possible that the square tube as a central support tube, a combination of metal profiles and composite panels, in particular sandwich panels is formed. The formation of the central support tube made of metal profiles, composite plates and / or trusses has the advantage that an extremely stable support tube with low weight can be achieved. In order to achieve a small deflection of the central support tube, it is also possible to form the support tube in the form of a hollow cylinder. In order to achieve a sufficient stability of the support tube for the use of the table surfaces, it is possible that stiffeners in the form of trusses are formed in the square tube. In one embodiment, it is possible for the quadrangular tube to have on one side at least one drive and a bearing point on a first head wall and at least one bearing point on a head wall opposite the first. The drive used here, for example, a hydraulic motor, an electric motor or an electric geared motor. However, this list is not exhaustive, it is possible depending on the size of the table surfaces and weight of the composite plates to be processed to use an individually selected drive as an electric, pneumatic or hydraulic drive with or without gear. In addition, the rotation module by means of a lever mechanism, which in turn is electrically, pneumatically or hydraulically driven, be equipped. The rotary module is preferably mounted or supported and driven on the ends forming a respective head wall. Drive and storage are preferably in a central axis of the rotary module.

According to a further embodiment of the large plate production device, it is possible for at least one further wall, in particular a dividing wall, to be formed in an interior of the carrier at a distance from a top wall. Such a partition wall is spaced apart and introduced parallel to the head wall in the central head tube. The Tennwand offers on the one hand the advantage of stiffening the central support tube and thus the rotation module. On the other hand, the partition wall may provide an additional bearing point for a shaft moving the rotary module or a bearing supporting the rotary module. Thus, it is possible that a drive shaft and / or bearing axis extends into the region of the partition wall and is mounted in the partition, so that the partition wall forms a bearing point for the support tube. The partition wall is preferably flat. if formed from a combination of metal profiles and composite plates, so that the partitions also have only a low weight but high stability. According to one embodiment, after arranging and / or processing the composite panels on the active table surface, the composite panels are fixed to the table surface so that the fixed composite panels can be moved to a position for heating and / or curing. In a preferred embodiment, the fixed composite panels are pivoted or moved by means of a rotary module into a position below the hall floor and come depending on the number of table surfaces on the rotary module in an embodiment of the rotary module with four table surfaces, for example vertical position in which harden the composite panels or heated so that the composite panels cure. For example, the composite plates are fixed by means of a vacuum on the table surface. For this purpose, the table surface in a preferred embodiment, a device for generating a vacuum.

In an advantageous embodiment, the device for generating a vacuum comprises a tube profile enclosing the table surface and / or dividing the table surface into regions. The tube profile in this case has openings in the direction of the user-facing surface, that is the active table surface, so that by means of a concern of a vacuum on the tube profiles, a negative pressure on the active table surface can be generated. In a preferred embodiment, the means for fixing comprises a vacuum cloth which at least partially spans the composite material plate. As a vacuum blanket here is a cloth referred to, on the one hand, the composite material plate over the entire surface and in one piece and covered by a vacuum over a longer period is preserved. For this purpose, the vacuum blanket is substantially diffusion-tight, so that no ambient air can penetrate through the vacuum blanket and the vacuum between the vacuum blanket and the composite material plate or the vacuum blanket and the table surface can penetrate. The vacuum cloth fixes the composite panel on the table surface by means of a vacuum applied to the tube profiles. In this case, it is possible by means of the vacuum blanket to exert such a high force on the composite material plate that a contact force sufficient for curing is exerted on the composite material plate and the composite material plate is securely fixed in an overhead position on the table surface. The vacuum blanket thus forms a means for fixing the composite sheet on the table top and is vacuum tight. Vacuum wipes are well known and EP 0 398 006 A2 is used only by way of example referenced, which discloses vacuum cloth. In addition, vacuum blankets made of natural rubber or rubber are known.

In a preferred embodiment, a vacuum sensor is arranged at least in the area of the table surface. The at least one negative pressure sensor is arranged on the table surface such that by means of the vacuum sensor, a negative pressure between the vacuum blanket and the table surface and / or the composite material plate and the table surface and / or in the region of the tube profile can be detected. It is possible to dispose a plurality of vacuum sensors, preferably distributed symmetrically on the table surface, so that even with different sizes of the composite panels accurate statement about the voltage applied between the vacuum blanket and the table surface vacuum is possible.

According to one embodiment, a vacuum reservoir and at least one vacuum pump is mounted inside the support tube, wherein the vacuum reservoir is connected via controllable valves with the tube profiles of the table top. Here, the vacuum pump is connected to the tube profiles of the table surface. In addition to a direct connection of the vacuum pump with the pipe profiles, it is also possible to integrate a vacuum reservoir into the interior of the support tube. The vacuum accumulator makes it possible to provide a sufficient negative pressure even with a large number of occupied with composite plates table surfaces. In a preferred embodiment, the vacuum reservoir comprises a tube storage, which can be arranged, for example, in a central axis of the rotary module, whereby advantageously a low moment load on the one or more drives can be achieved. In a further embodiment of the device for generating a vacuum, at least one further vacuum pump is arranged in the interior of the support tube. The at least one further vacuum pump can serve here as an additional or, in the case of a failure, as an alternative vacuum source. By way of example, a vacuum pump with a suction air quantity of 40 m ³ / h to 48 m ³ / h can be used, wherein the suction air quantity can be increased or reduced depending on the composite material plates to be processed.

A further advantage is achieved if the large-plate-making device has a closure frame enclosing the table surface at least partially, wherein the closure frame can be positioned toward the table surface and away from the table surface. Preferably, the vacuum blanket can be fixed on the table surface by means of the closure frame. If, in this case, the closure frame is arranged circumferentially around the table surface in such a way that the entire vacuum cloth covering the table surface is fixed between the closure frame and the table surface, then another securing device is required for generating tion of a continuous vacuum over a curing and / or storage time between the vacuum blanket and the table top or the vacuum blanket and the composite material plate achievable. If the closure frame is formed circumferentially and in one piece, then it is advantageous to supply the closure frame by means of a linear movement of the table surface or to position it towards the table surface and away from the table surface. As a result, on the one hand a uniform approach leading to a one-piece Verschlussrahmes to the table top and on the other hand a secure fixing of the vacuum blanket possible. A further development provides a customizable closure frame. An adaptation can be achieved, for example, by using a multi-part closure frame with interchangeable or additionally insertable frame parts.

A further advantage results when seals, in particular sealing lips, are fastened to the closure frame and / or to the table surface. The seals allow, for example, that even with a non-planar resting of the vacuum blanket, for example in wrinkling, a vacuum can be generated and continuously preserved. The seals are preferably made of an elastic plastic. In one embodiment, the seals are profiled and / or formed with cooperating and / or flat opposite sealing lips. A preferred embodiment is achieved when the closure frame encloses the table surface circumferentially and the closure frame has a seal which cooperates with a sealing lip on the table surface, so that by means of a positioning of the closure frame towards the table surface a full seal between the closure frame and the table surface is possible. By means of a full-circumferential seal an additional safeguard is provided for generating a vacuum on the table surface, in particular between the vacuum cloth and the table surface. For positioning of the closure frame, it is advantageous that the positioning of the closure frame and / or the bottom surfaces by means of hydraulic, pneumatic or electric drives, in particular by means of hydraulic linear actuators takes place.

For various composite panels and their applications, it may be advantageous for the composite panels to undergo heat treatment during curing. It may be advantageous in this case if the table surface and / or an environment of the large plate manufacturing device has a heating device. For example, a heat treatment creates biases in the composite panels, making the composite panels highly durable and temperature resistant. In a preferred embodiment, the heater is in the large plate making device integrated. Thus, it is possible, for example, to integrate the heating device directly into the table surface, so that an immediate heating of the composite material plate is made possible. This offers the advantage that low heat losses occur because the composite material plate indirectly, for example via the sandwich panels of the table surface, or directly, for example via heating elements in the table surface, is in contact with the heater. In addition, however, it is likewise possible for the heating device to cooperate with the large plate production device in such a way that at least the composite material plate can be heated. This can be done, for example, that the large plate manufacturing device or a passive table surface with a heat source, for example by means of at least one infrared radiator or heated air from at least one fan heater is applied. It is also provided according to an embodiment, a combination of a heater in the table surface with an external table surface acting on the heater. Another embodiment of a heating, which may be provided individually or in combination with another heating, uses an electrical resistance heating. Thus, a table surface may be provided with such a heating device. A further embodiment provides that additionally or alternatively, for example, the vacuum blanket is heatable, preferably electrically heated. A possible embodiment of an insertable electrical heating is principally disclosed in DE 10 2006 022319 A1, to which reference is made in this regard with regard to the materials used, the structure and the arrangement. So different power levels can be used for heating. Graphite coatings coated in glass cloth are preferably used to act as heating elements. A heating, preferably an electrical heating see, for example, carried out in a temperature range from 28 ° C to 50 ⁰ C _1, preferably between 30 ⁰ C and 40 ⁰ C. Also, the temperature may preferably be adjusted to a presettable temperature profile.

Furthermore, it is possible to provide a control or regulation. This can, for example, adapt an introduced heating energy into the composite panel. Also, so temperature profiles can be adapted to the processed composite plates to ensure improved curing. If, for example, in one embodiment a pressure is exerted on a fixed composite material plate, for example a pressing force, this may likewise be accompanied by heating. In this case, for example, by an adjustable pressure-temperature profile, a special strength of the composite material plate can be achieved. To be favoured In this case, a lower as well as an upper side of the composite plate with heat applied.

In a preferred embodiment of the invention, the rotational space can be walked on, so that the large-plate production device comprises a maintenance space located below the active table surface. By an embodiment of the rotational space as a walk-in space, on the one hand monitoring of the curing process is made possible. On the other hand, a maintenance and inspection room for, for example, the rotary module, the at least one drive and the at least one bearing can be created. In this case, the walk-in maintenance and inspection space is formed, for example, at least from the active table surface, the movable bottom surfaces and a box foundation delimiting the large-plate production device. An advantage arises when the maintenance and monitoring room at the same time has a heating device, so that the maintenance and monitoring room serves as a boiler room. The design of a boiler room, it is possible that the passive or passive table surfaces undergo continuous heating in the boiler room. The walk-in rotation space thus serves as a maintenance, monitoring and boiler room in such a case. In accordance with another aspect of the invention, which may be independently pursued, a method is proposed in which movement of a table surface of a large plate making apparatus is utilized. The method comprises at least the method steps: a) arranging at least one layer of a composite plate on a table surface, b) fixing the one or more layers of the composite plate on the table surface and c) moving the table surface from an active arranging, processing and fixing position in a passive position, preferably in a curing and / or heating position, wherein during or after the positioning of the table surface in the passive position another table surface is moved to the Anord- and processing position. According to a further development, a curing and / or heating position is assumed during or after the positioning of the table surface in the passive position. The method step of moving the table surface from an active arranging, machining and fixing position into a preferably passive curing and / or heating position provides a method with which a very economical production of composite plates is achieved.

An advantageous development results when the method steps a), b) and c) are repeated according to the number of table surfaces in the device. By a repetition of the work steps enables continuous production of composite panels. In one embodiment, it is possible that when the table top is moved from one position to another position it is at least partially lowered or raised. If the table surfaces are sunk into a hall floor of a factory assembly for the production of composite panels, and a rotary module is used for countersinking, this results in a space-saving production of composite panels.

In a preferred embodiment, the table surface is rotated by means of a rotary module from the Anord-, processing and fixing position in the curing and / or heating position. By turning the active table surface passes another table surface can get into the workspace of the user, so that minimizes the space required, reduces the handling costs for a bonded and not yet cured composite plate and production reliability is significantly increased.

A further advantage is achieved if, prior to a movement, preferably of the rotary module, at least one walkable bottom surface, preferably located in the swiveling range of the rotary module, is moved from a position flat with the table surface in the arranging, machining and fixing position into a position in which Moving preferably of the rotary module is made possible, and that after moving the rotary module, the bottom surface is again moved to the flat with the table surface in the Anord-, processing and fixing position. By means of moving a bottom surface surrounding the table surface, it is possible, on the one hand, to commit to the rotatably held table surface and, on the other hand, a floor surface pivoted out of the ground, for example, can serve as access protection. After moving it is possible that the composite material plate is heated directly or indirectly in the curing and / or heating position. The integration of a heating process in the process flow and directly in the large plate manufacturing device reduces the space required for the production of multiple composite panels and on the other hand enables continuous work.

An advantageous procedure results when the fixing of the composite material plate by means of a vacuum, in particular by means of a vacuum blanket, is performed. On the one hand, a vacuum cloth offers the advantage of being easy to lay on the composite material plate, and on the other hand, a vacuum cloth allows a uniform surface pressure to be achieved over the entire composite material plate. According to a further embodiment of the method, the vacuum blanket and / or the composite blanket fixed substance plate prior to positioning in the curing and / or Aufheizstadion means of a closure frame on the table surface. By means of the closure cream, the vacuum cloth and / or the composite material plate is securely positioned and even the heaviest composite plates are durable on the table surface. After the vacuum blanket is placed over the composite panel, evacuation of the area between the table top and the vacuum blanket is performed after fixing the vacuum blanket through the closure frame. The additional fixing by means of a closure frame supports the formation of a vacuum, since the closure frame additionally acts sealing. In addition, the closure frame has the advantages that on the one hand a high vacuum can be achieved and on the other hand that a vacuum can be maintained for a longer period, for example when a table surface serves as a storage area.

A further embodiment provides that a pressing device is used, by means of which the composite material plate can be fixed on the table surface.

For the rest, the device described above can preferably be used for carrying out the method. According to a further aspect of the invention, a factory assembly for producing a composite panel is achieved in that the large panel manufacturing device is at least partially embedded in a hall floor. Advantageous embodiments emerge from the subclaims. The arrangement of a large plate manufacturing device, which is at least partially admitted into the hall floor of the factory assembly, the possibility is created to save space and thus to minimize the space required for the production of a composite panel and in particular a panel van panels. In a first embodiment, it is possible that a table surface of the large plate manufacturing device is movable in the direction of the hall floor. Moving in the direction of the hall floor makes it possible here for the space thus freed up to be used for other work or for the production of further composite panels. In a further embodiment, the factory assembly is configured such that the table surfaces of the large plate manufacturing device are pivotally integrated into the hall floor. Due to the pivotable integration into the hall floor, only a table surface corresponding to the dimensions of the maximum panel trolleys is required as a space requirement in the factory layout and consequently as a hall area. In the past, at least two table surfaces were needed to allow parallel production of two panel van To enable material panels, so now the possibility is created, even with only a small amount of space in a factory hall to perform a parallel or a continuous production of composite panels. In addition, accounted for by the multi-purpose structure of the large plate manufacturing device at a production handling and storage costs. The thermosetting composite panels need not be transported and may, depending on the need and size of the large plate making device remain in the large plate maker and store there. If, for example, a high stock of inventories is required, the rotary module can be formed with a large number of table surfaces, for example, three, four, five, six, seven, eight, nine or ten table surfaces.

The integration or incorporation of the large plate production device in the hall floor of the factory further provides the advantage that the manufacturing hall can build lower because the panel van panels or composite panels are produced at a lower level. The low overall height is also achieved by virtue of the fact that a pivoting region of the large-plate production device comprises, at least in part, a space formed by a foundation embedded in the hall floor, in particular a box foundation or a caisson or a pit that has been concreted out. By using the foundation of the manufacturing hall, which extends into the hall floor, the manufacturing hall can have a lower height and also the transport of the finished composite panels can be done with deeper-built handling equipment, such as a hall crane. This is an advantage in particular because the composite panels are very large and can have dimensions of, for example, 15 meters by 3 meters.

In a further embodiment of the factory assembly, the foundation is made walkable, so that the foundation forms at least one maintenance level. A maintenance level has the advantage that the components of the large plate manufacturing device can be easily checked, maintained or repaired. It is also possible to monitor and / or control a composite sheet located in a curing and / or heating position.

A further advantage results when a control station for the operation of the large plate production device is arranged such that the large plate manufacturing device is visible at least in its active table surface for a user. The arrangement of the control station of the large plate manufacturing device in a user-visible area, for example, increases the security of the movement of the table surface. So can For example, the user visually verifies that the table surfaces are truly free, whether a composite panel is securely positioned on the table surface, and whether interference occurs during the movement of the tabletop.

Via further stairs with railing 20, 21 both bearings 12, 13 and a rotation module 24 with the passive table surfaces 22, 23 for monitoring and / or maintenance can be reached. The rotary module 24 is driven on one side by means of a motor-gearbox combination 25. In addition, the rotation module 24 is connected to the control station 7, wherein control, regulation or supply lines are routed to the rotation module 24 by means of an energy chain 26. The protective grid 5 and the pivotable bottom surfaces 9, 10 allow a safe processing of the active table surface 8. FIG. 2 shows a protruding from the hall floor 3 closure frame 27th

A side view along the section B-B in FIG. 1 is shown in FIG. 3. The same components are provided with the same reference numerals. Shown is a section through a central axis 28 of the large plate manufacturing device 1. At a head end 15, a drive unit 25 is arranged, for example, an electric motor, in particular a servomotor, a hydraulic, a pneumatic motor or similar drive or a combination of engine and a transmission can. The drive 25 is connected to a shaft 29 such that by means of the drive 25, a movement of the rotary module 24, in particular a rotation about the central axis 28 is made possible. The shaft 29 extends through the bearing 13 and a top end 15 forming the head wall 30 and additionally forms a bearing point 31 for a located inside the rotary module 24 partition 32. The partition wall 32 serves to stabilize the rotary module 24, a more uniform introduction of force in the Rotation module through the shaft 29 and in addition, the partition wall 32 counteracts a possible deflection of the rotation onsmoduls. At the head end 14 opposite the drive side, a dividing wall 33 is introduced into the interior of the rotary module 24. In this case, the partition wall 33 can again serve as a bearing point for an axis 35 extending through a head wall 34 and mounted in the bearing 12. The axle 35 is received in the bearing 12 supporting the rotation module 24, a bearing 36 located in the head wall 34 and the bearing 37 located in the partition wall 33.

Fig. 3 shows in section an active table surface 8, wherein the closure frame 27 is lifted from the table surface 8 or separated from the table surface 8. The table surface 8 is divided by means of tubular profiles 38 in areas 39. 3, only a few tube profiles 38 and regions 39 of the active table surface 8 and also the passive table surface 23 are provided with reference symbols for the tube profiles 38 and regions 39 for the better clarity of FIG. By dividing the table surfaces 8, 23 it is possible different composite panels 11 by means of a vacuum cloth 40 securely on the table surface 8, 27 to fix. The vacuum blanket 40 is shown in FIGS. 9 and 10. The regions 39 between the tube profiles 38 are preferably formed from a composite material plate, in particular a sandwich panel 39. The sandwich panel 39 here has the advantage that a slight construction of the rotary module 24 is given at the same time sufficient rigidity for committing and equipping the active table surface 8.

In the interior 41 of the rotary module 24, a vacuum accumulator 42 can be arranged. The vacuum storage 42 is supplied with a vacuum by means of a vacuum pump 43. In this case, at least one vacuum pump 43 is used, wherein alternatively a plurality of, preferably two, vacuum pumps 43 can be used. Via a connecting line 44, the tube profile 38 is acted upon by a vacuum from the tube store 42 and / or the vacuum pump 43. The pressurization of the tubular profile 38 with a vacuum is controllable by means of a valve 45. Merely for the sake of clarity, a connecting line 44 is shown by way of example in FIG. 3. It is also possible to control the active table surface 8 and / or the passive table surfaces 22, 23 or partial surfaces of the active table surface 8 and / or the passive table surfaces 22, 23 separately and to apply a negative pressure.

From Fig. 4 shows a side view of a factory assembly 2, wherein also the hall floor 3 and the box foundation 6 are shown. The box foundation 6 in this case extends into the hall floor 3, so that the rotation space 19 is located substantially below the hall floor 3. The box foundation 6 can also be described as a caisson or can be described as a cast-out pit. The protective grille 5 serve to prevent entry of the active table surface 8, when the rotation module 24, the active table surface 8 is rotated or moved to another position. 5, the protective grid 5 is shown in the view according to the arrow C in FIG. 4. The user N operates the large plate manufacturing device 1 from a control console or control station 7, wherein the control station 7 is seen from the active table surface 8 from behind the protective grid. The user N is therefore behind the protective grille 5 in a safe working area and at the same time is able to view the entire active table surface 8 or the rotation module. A section through the box foundation 6 according to the line DD of FIG. 4 is shown in FIG. 6. 6 shows the head wall 30 of the rotary module 24 with the table surfaces 8, 22, 41. The illustrated drive 25 comprises a motor, preferably an electric motor, which cooperates with a gear 47. The energy chain 26 allows rotational movements of the rotation module 24 from, for example, up to 360 °. It can also be used instead of the energy chain 26 with a rotary feedthrough, so that a rotation angle of more than 360 ° or an endless rotation of the rotary module 24 is possible. FIG. 7 shows a section according to the line EE from FIG. 4. FIG. 7 shows a section through the rotation module 24 in a region viewed from the drive 25 in front of the dividing wall 32. As can be seen, the exemplary embodiment shows a rotation module with four table surfaces 8, 22, 23, 46. The active table surface 8 is accessible to user N For example, the user N is able to apply, position, process and fix elements of a composite panel 48 on the active table surface 8. The active table surface thus serves for equipping and fixing a composite sheet. The other table surfaces 22, 23, 46 are passive table surfaces 22, 23, 46, in which composite panels 11 cure, are heated and harden or merely store. Fig. 7 shows the active table surface 8 with lifted off the active table surface 8 closure frame 27. The bottom surfaces 8, 9 are closed, that is they form with the hall floor 3 for the user N accessible area. The active table surface 8 with the closure frame 27 raised from the active table surface 8 is reproduced in detail in FIG. FIG. 8 shows a detailed view F from FIG. 7. A composite material plate 48 which has been applied to the active table surface 8 is shown. After assembling the composite panel members to form a composite panel 48, a vacuum blanket 40 is placed over the composite panel 48. The vacuum blanket 40 integrally covers the composite sheet 48, the active table surface 8, consisting of the tubular profiles 38 and the regions 39, and projects beyond the active surface 8. In this case, the vacuum blanket 40 at least extends over a frame 48 of the active table surface 8. By means of a lifting unit 49 fastened to the rotary module 24, the closing frame 27 can be moved in the direction of the arrow P and against the frame 48 in the direction of the active table surface 8.

As further illustrated in FIG. 8, the rotary module 24 has a central support tube 54 on which the table surfaces 8, 22, 23, 46 are mounted by means of bevelled profiles 55 are. The table surfaces 8, 22, 23, 54 are mounted at a distance from the central support tube 54 on the profiles 55. To save weight, the folded profiles are provided with openings 56. At the folded profiles 55 and / or the central support tube 54 holding elements 57 are fixed, which hold the lifting units 49, 58. The holding elements 57 are designed such that the holding elements 57 receive the lifting units 49, 58 for two different closure frames 27. Preferably, the lifting units 49, 58 are fixed in the holding elements 57 offset by 90 °, so that in each case by means of the lifting units 49, 58 a linear movement of the closure frame 27 in the direction of a normal N on the table surfaces 8, 22, 23, 46 is made possible. The central support tube 54 in turn is in turn made of stable, for example, metallic angle profiles 59 and composite panels 60, preferably sandwich panels 60. The angle profiles 59 can serve for stabilization and / or for mounting the holding elements 57 and / or the folded profiles 55. The sandwich panels 60 forming part of the central support tube serves, on the one hand, to stabilize the central support tube 54 and, on the other hand, to save weight.

A detailed view G of the frame 48 and the closure frame 27 of FIG. 8 is shown in FIG. 9. In the frame 48 of the active table surface 8, a lower circumferential seal 50, in particular a sealing lip 50 is arranged, which cooperates with an upper preferably also circumferential seal 51 in the closure frame 27. Preferably, the seals 50, 51 are formed profiled, wherein the seals 50, 51 are formed such that they support a formation of a vacuum between the vacuum blanket 40 and the active table surface 8. The closure frame 27 is fixed by means of a lifting unit 49 in the direction of arrow P movable on the rotary module 24. In this embodiment, the lifting unit 49 is designed as a linear unit 49, which is for example a pneumatic, hydraulic or electric linear unit 49. A piston rod 53 which moves out of a cylinder 52 lifts the closure frame 27 away from the active table surface 8 or the frame 48 or moves the closure frame 27 against the frame 48 of the active table surface 8.

After loading the active table surface 8 with a composite material plate 11, the active table surface 8 is moved by means of the rotation module 24 in a passive table surface position. Such a movement is shown in section along a line EE of Fig. 4 in Fig. 10 and shows a position in which the rotary module is moved by an angle. The illustration in FIG. 10 is labeled E'-E '. Fig. 10 shows the pivotable bottom surfaces 8, 9 in a folded out of the rotation range position, wherein the pivotable bottom surfaces at right angles to the hall floor 3 form and come substantially flush with the protective grid 5 to a standstill. The pivotable bottom surfaces thus form a safety device in the form of a walk-in protection for a user of the large-plate production device. Before twisting the rotary module 24, a composite material plate 11 is fixed on the active table surface 8, for which purpose the closure frame 27 moves in the direction of the active table surface and comes to rest on the frame 48, as shown in detail in FIG. The composite panels 11 are fixed by means of the vacuum cloth 40 on the table surface 8. In this case, the vacuum cloth 40 is clamped between the closure frame 27 and the frame 48 and the tube profiles 38 are subjected to a vacuum, so that a vacuum is created between the vacuum cloth 40, the composite plate 11 and the table surface 8.

For the determination, control or regulation of the vacuum between the vacuum blanket and the table surface and / or a vacuum between the composite material plate 11 and the table surface 8, pressure sensors 61 are integrated into the active table surface 8 and the passive table surfaces 22, 23, 46. Other pressure sensors may also be integrated in the connecting line 44 and the tube memory 42. The vacuum between the vacuum blanket 40 and the table surface 8 and the composite plate 11 is created by applying a negative pressure to the tube profile 38. As shown by way of example in FIG. 11, the tube store 42 is connected to the tube profile 38 via a connecting line 44. For example, through openings on a surface N of the tube profile 38 facing the user N, the air located between the vacuum cloth 40 and the table surface 8 and / or the composite material plate 11 can be sucked off. The self-adjusting by the suction of air vacuum is fixed and compresses the composite plate 11 on the table surface.

FIG. 12 shows a detailed view according to the detail I. FIG. 12 shows the composite plate 11 fixed on the active table surface 8 and the closed closure frame 27, the lower seal 50 and the upper seal 51 lying on top of one another and thus supporting the formation of a vacuum on the table surface 8. Here, the closure frame 27 acts with the force F on the frame 48, that the vacuum blanket 40 is securely held and circumferentially sealing closes.

13 shows a plan view of a factory assembly 62 with a Großplattenher- actuator 1, as part of a manufacturing process of, for example, van 63. The large plate making device 1 is embedded in the hall floor 3, wherein the active table surface 8, the bottom surfaces 8, 9, the control station 7 and the access device 4 can be seen in the plan view. The factory assembly 62 further includes a foam bearing 64, a bearing for sheets 65 provided, for example, as a coil, a hazardous material storage for adhesive 66, a mixing station for adhesive 67, a finishing table 68, a profiled bearing 69, a structural set mounting table 70, a processing means 71, such as a circular saw, a magazine 72 and a mounting plate for a door production 73. The factory assembly 62 is subdivided into a production area 74 and a storage area 75, for transporting the panel vans 63.

To produce a composite material panel 11, for example, profiles, structural elements, sheets and foam elements are joined to the active table surface 8 and / or adhesively bonded. After assembling the composite material plate 11 on the active table surface 8, the composite material plate 11 can be fixed on the active table surface 8 by means of a vacuum cloth 40 and a closure frame 27. The user N of the large-plate production device 1 is then able to move the active table surface 8 into a passive position by means of the control station 7, whereby the composite material plate 11 can be moved into the hall floor 3, for example by means of a rotary module 24. For moving the rotary module 24, the movable floor surface 9, 10, for example, pivot into a position protruding from the hall floor and form part of the safety device. For example, if the large-plate-making apparatus is equipped with four table surfaces 8, 22, 23, 46, and if the rotation module 24 is rotated by 90 °, the composite material plate 11 enters a vertical curing and / or heating position. After curing of the composite sheet 11, the composite sheet 11 can be post-processed on the table for reworking 69 and is then available, for example, for mounting on a vehicle.
