[0003] Assembly platform and assembly station

[0004] The present invention relates to an assembly platform for mounting a rectangular wooden frame for a building component. The invention also relates to an assembly station equipped with at least one such assembly platform.

[0005] From AT 510 797 A1, a timber-framed building element is known in which a timber frame is formed from I-beams into which prefabricated straw bales are clamped as insulation and filled with a hardening clay compound. For this purpose, straw bales pre-tensioned with cords are used, the cords of which are removed after insertion into the timber frame, allowing the pre-tensioned straw to expand and conform to the I-beams. For high thermal insulation, the straw bales are inserted into the timber frame in such a way that the direction of the straw in the bale runs parallel to the frame plane. Sufficient stability in the known building element is achieved by means of diagonal sheathing made of wooden boards attached to the I-beams.

[0006] AT 000722 U1 discloses a manufacturing device for producing a wooden beam comprising interconnected wooden elements. The manufacturing device includes a press stand with support surfaces for the wooden elements and a press device with an adjustable pressure element that is movable at an angle of 90° to the support surface.

[0007] DE 20 2009 002 437 U1 discloses an assembly device for assembling wall elements in timber frame or post-and-beam construction. The assembly device has a grid-shaped assembly wall which is connected with a small 23.01.2026

[0008] 2

[0009] It is arranged at an inclination relative to the vertical and on which parts of the wall elements to be manufactured can be placed and assembled for processing.

[0010] WO 96 / 05 036 A1 describes a production plant for manufacturing a raw profile from rod- or board-shaped lamellae. The production plant includes a press with several clamping devices and clamping drives.

[0011] From DE 10 2023 211 651 .0 a modular building element for erecting walls of a building is known, which has a rectangular wooden frame in which compartments filled with straw are formed.

[0012] Such a timber frame has a width direction, a height direction, and a depth direction, all of which run perpendicular to each other. To erect a wall of a building, the structural element created using the timber frame is positioned so that the timber frame is upright. In this upright position, the width and depth directions run horizontally, while the height direction is vertical. The timber frame has several straight timber beams, which, in this upright position, form two outer horizontal frame beams, forming an upper and a lower frame beam, and two outer vertical frame beams, forming a left and a right frame beam, which are supported by the two horizontal frame beams.In particular, the wooden beams can also form at least one, and preferably several, internal vertical support beams arranged between the vertical frame beams and supported by the horizontal frame beams. The wooden beams or the frame beams define a frame width measured in the lateral direction, a frame depth measured in the vertical direction, and a frame height measured in the vertical direction. 23.01.2026.

[0013] 3. The height of the wooden frame. Each wooden frame also has several straight wooden members that, when the frame is oriented vertically, extend horizontally from one vertical frame member (e.g., the left frame member) through the support beams to the other vertical frame member (e.g., the right frame member), forming several compartments within the frame. When the frame is oriented vertically, these compartments are bounded upwards by the upper frame member or at least one of the wooden members, downwards by the lower frame member or at least one of the wooden members, to the left by the left frame member or one of the support beams, and to the right by the right frame member or one of the support beams.In the wooden frame, the ends of the wooden slats are inserted into end openings formed in the respective vertical frame beams (left and right frame beams) and passed through through openings formed in the support beams. The end openings can be blind holes or through openings.

[0014] In order to be able to produce a building relatively cheaply using such building elements, it is necessary to be able to manufacture the building elements and especially the associated wooden frames themselves as cheaply as possible and with high quality and precision.

[0015] The present invention addresses the problem of providing a method for the production of such wooden frames that is characterized in particular by inexpensive production with high quality and dimensional accuracy.

[0016] This problem is solved by the subject matter of the independent claim. Advantageous embodiments are the subject matter of the dependent claims. 23.01.2026

[0017] 4

[0018] The invention is based on the general concept of aligning the beams on the assembly platform relative to each other so that they occupy the positions they will occupy in the finished timber frame. Wood is a natural product, meaning that the resulting timber beams can warp due to varying temperatures and humidity. By aligning the beams, it is particularly possible to align the openings—that is, the end openings and the through-openings—formed for the respective timber in the left frame beam, the right frame beam, and the support beams, so that they follow each other in a straight line in the lateral direction, thus allowing the respective timber to be guided through the through-openings in its longitudinal direction and inserted into the openings.To improve the assembly of the wooden rods, it is also suggested to align and guide them with respect to the openings.

[0019] Specifically, the invention proposes an assembly platform comprising a base frame, a beam holder, and a rod guide. The base frame has a front surface for positioning the wooden beams, which form the horizontal frame members, vertical frame members, and support beams in the finished wooden frame. The beam holder is configured to align and fix the wooden beams against the front surface of the frame in predetermined positions, such that the wooden beams fixed in these predetermined positions form the horizontal frame members, vertical frame members, and support beams in the finished wooden frame, and can be fastened to one another. In other words, the beam holder enables the positioning and fixing of the wooden beams relative to each other in a spatial arrangement that the wooden beams also exhibit in the finished wooden frame.The staff command is for aligning and leading on January 23, 2026.

[0020] The wooden rods are configured for easy insertion through the openings in the support beams and into the end openings of the respective vertical frame members. This simplifies the assembly of the wooden rods. However, the wooden rods can warp due to variations in humidity and temperature. For high stability of the wooden frame, it has proven advantageous for the wooden rods to have a non-circular cross-section. Therefore, wooden rods with a rectangular, and preferably a square, cross-section are preferred for the wooden frame. Accordingly, the openings and end openings adapted to these rods can also have a round or non-circular, and in particular rectangular or square, cross-section that matches the rod cross-section.With a square rod cross-section, a suitable circular opening can have a diameter that essentially corresponds to the diagonal of the square rod cross-section. Precise alignment and guidance of these non-circular wooden rods in relation to the openings is extremely advantageous for inserting or passing them through the corresponding round or non-circular openings. The assembly platform presented here enables the automated production of wooden frames with high manufacturing quality, characterized in particular by high dimensional accuracy and comparatively tight tolerances.

[0021] In the present context, "configuration" is synonymous with "design" and / or "setup" and / or "programming", so that the phrase "configured so that" is synonymous with the phrase "designed and / or set up and / or programmed so that".

[0022] The base frame defines a longitudinal direction, a transverse direction, and a normal direction, all perpendicular to each other. The longitudinal and transverse directions define a plane to which the front of the frame is parallel. 23.01.2026

[0023] 6 extends. The front of the frame faces away from the rear of the frame in the normal direction, which runs perpendicular to the aforementioned plane. The wooden frame can be assembled on the base frame in either a standing or lying position. When the wooden frame is arranged horizontally on the base frame, the vertical direction coincides with the longitudinal direction, the horizontal direction with the transverse direction, and the vertical direction with the normal direction. When the wooden frame is arranged vertically on the base frame, the vertical direction coincides with the transverse direction, the horizontal direction with the longitudinal direction, and the vertical direction with the normal direction.

[0024] According to an advantageous embodiment, the assembly platform can have a lifting device configured to adjust the wooden frame relative to the front of the base frame when the wooden beams are attached to each other and the wooden rods to the wooden beams, and when the beam clamp has released the wooden beams. This allows the wooden frame to lift away from the front of the base frame in the depth direction and be removed from the base frame transversely to this depth direction, i.e., in particular in the height and / or width direction. The lifting device thus simplifies the removal of the finished wooden frame from the base frame and therefore from the assembly platform.

[0025] According to an advantageous embodiment, the lifting device can have at least one lifting beam and at least one lifting drive for adjusting the lifting beam relative to the base frame in the depth direction of the wooden frame between an assembly position and a transfer position. Advantageously, at least two such lifting beams can be provided, which are sensibly adjustable synchronously. In the assembly position, the respective lifting beam is arranged at the front of the frame in such a way that the wooden beams can be positioned, aligned, and fixed against the front of the frame. (With other 23.01.2026)

[0026] 7

[0027] In other words, each lifting beam is configured so that, in the assembly position, it does not obstruct the positioning, alignment, and fixing of the timber beams. In the transfer position, each lifting beam is raised sufficiently from the front of the frame in the direction of depth to allow the timber frame to be released from the beam support and the guide rails in the direction of depth, thus enabling the timber frame to be removed from the base frame transversely to the direction of depth. The lifting drive can be conveniently attached to the base frame. It is advantageous to provide two lifting drives for each lifting beam, for example, in the form of pneumatic or hydraulic piston-cylinder units, spaced apart from each other along the length of the lifting beam and interacting with the lifting beam, particularly outside the timber frame.

[0028] According to an advantageous embodiment, the lifting device can optionally include at least one carriage and a carriage drive for adjusting the carriage relative to the base frame transversely to the depth direction of the wooden frame between an assembly position and a transfer position. Advantageously, at least two such carriages can be provided, which are sensibly adjustable synchronously. In its assembly position, each carriage is positioned at the front of the frame such that, on the one hand, the wooden frame can be assembled without interference, and on the other hand, the assembled wooden frame is transferred by the respective lifting beam to the carriage(s) in its transfer position. Subsequently, each carriage can adjust the wooden frame relative to the base frame transversely to the depth direction, in particular raising or lowering it.

[0029] According to an advantageous embodiment, the beam holder for several wooden beams can have several pressure elements on the front of the frame, which are adjustable between a fixing position and a release position, and several Wi- 23.01.2026

[0030] The frame features eight support elements. In the release position, the pressure elements allow the wooden beams to be positioned against the front of the frame and the support elements. When moving from the release position to the locking position, the pressure elements press the respective wooden beam against the support elements, thereby aligning and fixing the beam in the predetermined position on the base frame. When moving from the locking position to the release position, the pressure elements release the wooden beams, allowing the assembled wooden frame to be lifted from the base frame in the depth direction, particularly with the aid of the lifting mechanism. Pressing the wooden beams against the support elements using the pressure elements can, for example, correct any warping of the wooden beams.

[0031] All pressure elements that follow one another in the transverse direction together form a pressure string. All abutment elements that follow one another in the transverse direction form an abutment string. The beam support has several pressure strings and several abutment strings that are adjacent in the longitudinal direction.

[0032] According to an advantageous embodiment, the beam support can be configured for the synchronous adjustment of all pressure elements of such a pressure string between the release position and the locking position. For example, the beam support can have a support linkage that is drive-connected to all pressure elements of such a pressure string, and a support drive that is drive-connected to the support linkage, so that the support drive, via the support linkage, allows all pressure elements of the respective pressure string to be synchronously adjusted between the release position and the locking position. This makes it possible to first arrange all wooden beams on the base frame and then 23.01.2026

[0033] 9 can be aligned synchronously with the base frame and each other via the beam support and fixed synchronously to the base frame.

[0034] According to a practical embodiment, the support linkage can be arranged on the rear side of the base frame, facing away from the front. The base frame has a bearing plane located between the front and rear of the frame, on which the pressure elements are rotatably mounted. The pressure elements extend through this bearing plane and are connected to the support linkage at the rear of the frame via a drive mechanism. In this way, a comparatively large number of pressure elements can be provided at the front of the frame for aligning and fixing a correspondingly large number of wooden beams, which are connected to each other and to the support drive at the rear of the frame via the common support linkage.

[0035] The support level can have several support plates, on each of which at least one of the pressure elements is rotatably mounted and on which at least one of the abutment elements is arranged. The support plates are attached to the base frame. The support plates can be arranged and attached to the base frame in a checkerboard pattern. Such support plates simplify the construction of the holding device on the base frame. By using such support plates to create the support level, the mounting platform is virtually infinitely scalable, making it particularly easy to adapt the mounting platform to different sized wooden frames.

[0036] According to an advantageous embodiment, the pressure elements and the abutment elements for aligning the vertical frame beams and the vertical support beams parallel to each other and for positioning them at a predetermined horizontal distance from each other can be configured. 23.01.2026

[0037] 10

[0038] A particularly advantageous design is one in which the beam support includes an alignment device. This device comprises a mobile alignment unit on the front of the frame, adjustable relative to the base frame in the vertical direction of the wooden frame or in the longitudinal direction of the base frame, and a stationary alignment unit fixed to the base frame. Furthermore, the alignment device can be configured to align the vertical frame beams and vertical support beams relative to the horizontal frame beams. The mobile alignment unit presses one horizontal frame beam against the vertical frame beams and vertical support beams, and in turn presses these against the other horizontal frame beam, which is thereby pressed against the stationary alignment unit, against which it then rests.

[0039] Aligning the vertical frame beams and vertical support beams with the horizontal frame beams can be advantageously carried out while the pressure elements are still in their release position. Alternatively, in another embodiment, the pressure elements, the abutment elements, and the alignment device can be coordinated such that the alignment device can align the vertical frame beams and vertical support beams relative to the horizontal frame beams while the pressure elements are in their locking position. In other words, the alignment device is configured to overcome the holding force with which the pressure elements press the vertical frame beams and vertical support beams transversely against the abutment elements in the longitudinal direction.This ultimately ensures that the pressure elements, together with the abutment elements, perform a transverse alignment of the vertical frame beams and vertical support beams, while the alignment device performs a longitudinal alignment of the vertical frame beams and vertical support beams. 23.01.2026.

[0040] 11

[0041] According to an advantageous embodiment, the rod guide may have several guide elements and several locking elements for each wooden rod. The guide elements are adjustable between a guide position and a release position and have at least one guide contour open transversely to the longitudinal direction of the rod for the respective wooden rod. The locking elements are adjustable between a closed position, in which they close the guide contours of the guide elements moved into the guide position transversely to the longitudinal direction of the rod, and an open position, in which they open the guide contours of the guide elements moved into the guide position transversely to the longitudinal direction of the rod. The closed guide contours have a guide cross-section complementary to the rod cross-section, which can be rectangular and preferably square.Furthermore, the guide elements and the locking elements can be coordinated such that, in both the guided and locked positions, the guide contours are aligned longitudinally with the through-openings and end-openings of the vertical frame beams, which are aligned and fixed to the front of the frame. Simultaneously, the wooden rods are held in the guide contours transversely to the longitudinal direction of the rods and guided along their length. This allows the wooden rods to be guided through the through-openings and inserted into the end-openings in both the guided and locked positions.In the release position of the guide elements, the respective guide contour is positioned outside the respective wooden rod and releases the respective wooden rod in the depth direction, so that a mounted wooden frame can be lifted off the base frame in the depth direction, particularly with the aid of the lifting device. In this way, after the wooden rods have been passed through the openings and inserted into the end openings and fixed to the wooden beams, the fully assembled wooden frame can be lifted off on January 23, 2026.

[0042] 12 can be removed from the base frame.

[0043] All locking elements that are adjacent in the transverse direction form a locking strand. Several locking strands are adjacent in the longitudinal direction.

[0044] According to an advantageous embodiment, the rod guide can be configured for the synchronous adjustment of all locking elements of one of the locking trains between the open and closed positions. For this purpose, the rod guide can have a guide rod connected to all locking elements of one of the locking trains via a drive mechanism, and a guide drive connected to the guide rod, so that the guide drive allows all locking elements of the respective locking train to be adjusted synchronously between the open and closed positions via the guide rod. This simplifies the assembly of the wooden rods.

[0045] Advantageously, the guide rod can be arranged on the rear of the frame, facing away from the front. The base frame has a bearing plane located between the front and rear of the frame, on which the locking elements are rotatably mounted. The locking elements can penetrate the bearing elements and be connected to the guide rod via a drive mechanism at the rear of the frame. Here, too, a spatial separation is created between the functional components of the rod guide and the drive mechanism of the functional components, providing sufficient working space at the front of the frame for handling the wooden rods and beams. The bearing plane can also be formed using several bearing plates. At least two locking elements can be rotatably mounted on at least one such bearing plate. The bearing plates can also be attached to the base frame. 23.01.2026

[0046] 13

[0047] A particularly advantageous embodiment is one in which the bearing plates, on which the locking elements are rotatably arranged, are formed by the same bearing plates mentioned above, and on which one of the pressure elements and one of the abutment elements are arranged. Accordingly, two of the locking elements, one of the abutment element, and one of the pressure elements can be arranged on each bearing plate.

[0048] According to an advantageous embodiment, the respective guide element can have at least two such guide contours that are spaced apart from each other in the depth direction. Advantageously, the respective closing element can be configured such that, in the closed position, it closes the at least two guide contours transversely to the longitudinal direction of the rod, and in the open position, it opens the at least two guide contours transversely to the longitudinal direction of the rod. In particular, this allows the respective guide element to be configured for the simultaneous alignment and guidance of at least two wooden rods that are adjacent in the depth direction.By providing multiple guide contours that can be opened and closed using the same locking element, it is possible to define at least two different positions for the wooden rods with respect to the depth direction and / or to define a corresponding position for at least two wooden rods with respect to the depth direction. Accordingly, different wooden frames can be created using the rod guide, in which several wooden rods are arranged adjacent to each other in the depth direction to form the compartments. Likewise, different wooden frames can be produced on the same assembly platform, differing, for example, in their frame depth as measured in the depth direction. A different frame depth also results in a different position of the wooden rods with respect to the frame depth.

[0049] According to a particularly advantageous embodiment, it can now be provided for 23.01.2026

[0050] 14. The guide elements of the rod guide are formed by the pressure elements and the abutment elements of the beam support. For this purpose, the guide contours of the guide elements are designed on the pressure elements and the abutment elements such that the fixed position of the pressure elements simultaneously forms the guide position of the guide elements. Furthermore, it can be provided that the abutment elements are adjustable between the guide position and the release position, with the abutment elements serving as abutments for the wooden beams in both the guide position and the release position. The wooden beams are pressed against the abutment elements by means of the pressure elements. This results in an extreme simplification of the assembly platform.

[0051] According to an advantageous embodiment, the locking elements of the rod guide can be configured as first and second locking elements. The first locking elements interact with the guide contours formed on the pressure elements, while the second locking elements interact with the guide contours formed on the abutment elements. This measure also simplifies the construction of the assembly platform, thus providing a comparatively large amount of space at the front of the frame for handling the beams and wooden rods.

[0052] According to an advantageous embodiment, the pressure elements can be adjusted to an intermediate position between the locking position and the release position, in which the wooden beams are released in the depth direction, but the wooden rods are still held in the depth direction by the guide contours. Optionally, the abutment elements can also be adjusted to an intermediate position between the guide position and the release position, in which the wooden rods are held in the depth direction by the guide contours. The intermediate position of the abutment elements- 23.01.2026

[0053] Step 15 is not strictly necessary if the abutment elements are adjustable separately from the pressure elements. However, it is advantageous to configure the mounting drive so that it can adjust the pressure elements and the abutment elements synchronously. This allows the mounting drive to adjust the pressure elements between the release and locking positions, and simultaneously, the abutment elements between the open and closed positions. When the pressure elements are adjusted to their intermediate position, the abutment elements are also adjusted to their intermediate position at the same time. It is important that even in the intermediate position of the abutment elements, the wooden rods are still held and guided in the depth direction by the guide contours.

[0054] The intermediate position of the pressure elements can be used in particular to attach another wooden beam without losing the alignment and fixing of the other wooden beams and rods.

[0055] An assembly station according to the invention is configured for assembling wooden frames for building components and is equipped for this purpose with at least one assembly platform of the type described above. Furthermore, the assembly station can be equipped with at least one assembly robot for positioning the wooden beams, fastening the wooden beams to one another, inserting the wooden rods, and fastening the wooden rods to the wooden beams. Such an assembly station can, for example, form one of several production stations in a production line for manufacturing the building components.

[0056] According to an advantageous embodiment, the respective mounting platform in the assembly station can be arranged such that the front of the frame lies in a mounting plane that is inclined to a vertical direction in a range of 5° to 45°. The mounting plane is inclined to the vertical direction. 23.01.2026

[0057] 16. The mounting plane is inclined at least by 10°, preferably by at least 15°, preferably by at least 20°, preferably by at least 25°. The mounting plane is inclined relative to the vertical direction by a maximum of 40°, preferably by a maximum of 35°, preferably by a maximum of 30°, preferably by a maximum of 25°. Preferably, the inclination between the mounting plane and the vertical direction can be in a range of 20° to 30°. This measure allows the reach of the assembly robot to be optimally utilized.

[0058] In an advantageous embodiment, the respective assembly platform in the assembly station can be arranged such that the wooden frame is mounted horizontally. When the wooden frame is mounted horizontally, it is rotated 90° about an axis of rotation parallel to its depth. The horizontal wooden frame rests on the left or right frame beam. In contrast, a vertically mounted wooden frame rests on the lower frame beam or, if the wooden frame is upside down, on the upper frame beam. When the wooden frame is mounted horizontally, its width extends in a vertical plane within the assembly station, while its height extends in a horizontal plane.It has been shown that when the wooden frame is mounted horizontally, gravity can be used to support and simplify assembly, as the wooden rods can then be guided from top to bottom through the openings and inserted into the end openings of the left or right frame beam from above. This significantly simplifies manufacturing. At the same time, it significantly reduces the horizontal space required by the assembly station.

[0059] According to another advantageous embodiment, the assembly station can have two such assembly platforms and two such assembly robots. 23.01.2026

[0060] 17. Furthermore, the assembly station can have a rotating frame for holding the two assembly platforms, which can be rotated at least 180° about a vertical axis and which is arranged between the two assembly robots. This allows the assembly station to produce two wooden frames simultaneously. At the same time, the assembly station requires hardly any additional horizontal installation space.

[0061] A particularly advantageous configuration is one in which the assembly station has an assembly control system that is coupled to the rotating frame, the assembly platforms, and the assembly robots, and which is also configured to produce the wooden frames according to a four-stage process. In other words, the assembly control system is configured to carry out a four-stage process for manufacturing the wooden frames.

[0062] In the first stage of the four-stage process, the first assembly robot is controlled to attach the upper frame beam, the lower frame beam, and the support beams, as well as at least one frame beam from the left and right frame beams. Specifically, it attaches either only the left frame beam if the timber frame is being assembled lying on the left frame beam, or only the right frame beam if the timber frame is being assembled lying on the right frame beam, or both the left and right frame beams to the respective assembly platform. If the end openings of the left and / or right frame beam are configured as through-holes, both the left and right frame beams can be attached to the respective assembly platform.If, on the other hand, the end openings of the left frame beam and the right frame beam are configured as blind holes, only one of these two beams, i.e. either the left frame beam or the right frame beam, will be used in the assembly - 23.01.2026.

[0063] 18 platforms attached.

[0064] In the second stage of the four-stage process, the other or second assembly robot is specifically controlled to guide the wooden rods through the openings in the support beams and insert them into the end openings of at least one of the frame beams (left and right). If the end openings of one of the frame beams (left and right) are configured as through openings, the wooden rods can also be guided through these openings.

[0065] In the third stage of the four-stage process, the first assembly robot is controlled to position the other left and right frame beams on the upper and lower frame beams, respectively, such that the wooden battens are inserted into the end openings of these frame beams. This assembly step can, of course, be omitted if both the left and right frame beams have already been attached in the first stage. In the third stage, the first assembly robot is controlled to fasten the wooden beams together. For this purpose, the first assembly robot can, for example, be equipped with a nail gun that hammers or shoots appropriately sized nails into the wooden beams to fasten them together.

[0066] In the fourth stage of the four-stage process, the second assembly robot is specifically controlled to attach the wooden rods to the wooden beams. Also in this fourth stage, the assembled wooden frame is removed from the assembly platform. The second assembly robot can, for example, be equipped with a nail gun that hammers or shoots appropriately sized nails into the wooden rods and beams to secure them. (23.01.2026)

[0067] 19

[0068] to attach wooden rods to the wooden beams.

[0069] According to another embodiment, the assembly control system can also be configured to control the two assembly platforms, the two assembly robots, and the turntable according to a work process in four successive and repeating steps, such that two wooden frames are assembled simultaneously according to the four-step process, but offset from each other by one step. This allows twice as many wooden frames to be assembled in the same time period. For example, it can be provided that in a first rotational position of the turntable, the first assembly platform faces the first assembly robot, while the second assembly platform faces the second assembly robot. In a second rotational position of the turntable, rotated 180° relative to the first, the first assembly platform then faces the second assembly robot, while the second assembly platform faces the first assembly robot.It can be expediently and optionally provided that the first assembly robot is configured to work according to the first and third cycles, while the second assembly robot is configured to work according to the second and fourth cycles. This allows for the implementation of an assembly process with the four work steps described below.

[0070] In the first step, the initial rotation position is established, and the first assembly robot works on the first assembly platform according to the first cycle, positioning the wooden beams, if necessary, except for one of the frame beams. Meanwhile, the second assembly robot works on the second assembly platform according to the fourth cycle, attaching the wooden rods to the wooden beams. The completed wooden frame is then removed from the second assembly platform. January 23, 2026

[0071] 20

[0072] In a second work step, the second rotation position is present and the first assembly robot now works on the second assembly platform according to the first cycle and positions the wooden beams for another wooden frame, while the second assembly robot works on the first assembly platform according to the second cycle and inserts the wooden rods.

[0073] In a third step, the first rotation position is again present and the first assembly robot works on the first assembly platform according to the third cycle, attaching the missing frame beam if necessary and fastening the wooden beams together, while the second assembly robot works on the second assembly platform according to the second cycle and inserts the wooden rods into the wooden frame there.

[0074] In a fourth step, the second rotation position is again present. The first assembly robot works on the second assembly platform according to the third cycle, attaching any missing frame beams and fastening the wooden beams together, while the second assembly robot works on the first assembly platform according to the fourth cycle, attaching the wooden rods to the wooden beams, and then the finished wooden frame is removed from the second assembly platform.

[0075] After the fourth step, the assembly process is repeated and begins again with the first step.

[0076] If the respective wooden frame is to be fitted with a door opening and / or a window opening, further assembly steps can follow the fourth work step, which can be carried out outside the assembly platform. It is also conceivable that these additional assembly steps could be carried out on January 23, 2026.

[0077] to integrate 21 into the first and / or fourth work step.

[0078] Preferably, the end openings of the left and right frame beams are configured as blind holes, so that for the assembly of the wooden rods, it is necessary to arrange all but one of the left and right frame beams on the base frame, allowing the wooden rods to be guided from the missing frame beam through all the openings in the support beams and inserted into the end openings of the left or right frame beam already attached to the base frame. The remaining right or left frame beam can then be assembled, with the wooden rods being inserted into the end openings of this right or left frame beam, respectively.In another embodiment, it can be provided that at least on one frame beam of the left and right frame beams the end openings are also configured as through openings, so that it is possible to arrange all wooden beams on the base frame in order to then guide the wooden rods through the end openings of one frame beam of the left and right frame beam, which are designed as through openings, and through the through openings of the support beam, and to insert them into the end openings of the other frame beam of the left and right frame beam, which can be configured as blind holes or also as through openings.

[0079] According to an advantageous embodiment, several support rods support the wooden frame, particularly on the underside of the wooden frame. It may be advantageous for one or more, and in particular all, of the support rods to be configured to rotate about their longitudinal axis and to be rotatably driven about their longitudinal axis by one or more drive devices. Several, and in particular all, of the support rods can be rotatably driven by a common drive device. The drive device can be a chain drive. 23.01.2026

[0110] As shown in Figure 1, a rectangular wooden frame 1 has a width direction B, a height direction H and a depth direction T, which are perpendicular to each other. 23.01.2026

[0111] 25. In Figure 1, the wooden frame 1 is arranged vertically. Consequently, the vertical direction H runs vertically, i.e., parallel to the direction of gravity G, which is indicated by an arrow in Figure 1. The horizontal direction B and the vertical direction T run horizontally, i.e., perpendicular to the direction of gravity G.

[0112] The timber frame 1 has several straight timber beams 2 which, when the timber frame 1 is in a vertical position, form two outer horizontal frame beams 3, two outer vertical frame beams 4, and several inner support beams 5. The two horizontal frame beams 3 form an upper frame beam 30 and a lower frame beam 3u. The two vertical frame beams 4 form a left frame beam 4I and a right frame beam 4r. The upper frame beam 30 is supported by the vertical frame beams 4 and the support beams 5 against the lower frame beam 3u. The timber frame 1 also has several straight timber rods 6 which extend horizontally when the timber frame 1 is in a vertical position. The timber rods 6 extend from one vertical frame beam 4 through the support beams 5 to the other vertical frame beam 4.Using the wooden rods 6, several compartments 7 are formed in the wooden frame 1, which in the finished building element are filled with a load-bearing and insulating material, preferably straw. These compartments 7 are bounded above by the upper frame beam 30 or by at least one of the wooden rods 6, below by the lower frame beam 3u or at least by one of the wooden rods 6, to the left by the left frame beam 4I or by one of the support beams 5, and to the right by the right frame beam 4r or by one of the support beams 5. In Figure 1, the compartment labeled 7.1 is bounded above by the upper frame beam 30, below by two wooden rods 6, to the left by the left frame beam 4I, and to the right by one of the support beams 5. The compartment labeled 7.2 is bounded above and below by two wooden rods 6 each, and to the left by one of the support beams 23.01.2026.

[0113] 26

[0114] 5 and to the right by the right frame beam 4r. The compartment marked 7.3 is bounded at the top by two wooden rods 6, at the bottom by the lower frame beam 3u, and to the left and right by one of the support beams 5 each.

[0115] In the wooden frame 1, the wooden rods 6 are inserted with their longitudinal ends 8 into end openings 9 formed in the respective vertical frame beams 4. In contrast, through-openings 10 are formed in the support beams 5, through which the wooden rods 6 pass. The inner cross-sections of the end openings 9 and the inner cross-sections of the through-openings 10 are adapted to the outer cross-sections of the wooden rods 6 in such a way as to provide a positive fit. In particular, a fit with minimal play, a transition fit, or a fit with minimal interference fit can be provided.

[0116] The wooden frame 1 shown in Figure 1 therefore has four frame beams 3, 4, three support beams 5, and five pairs of two wooden rods 6, forming a total of twenty-four compartments 7. In the finished wooden frame 1, the wooden beams 2 are fastened to one another, in particular by means of nails and / or screws and / or adhesive. In the finished wooden frame 1, the wooden rods 6 are fastened to the wooden beams 2, in particular by means of nails and / or screws and / or adhesive.

[0117] There are different variants of the building element that can be produced using the wooden frame 1, which gives the building element a modular character.

[0118] In its simplest form, the building element can be a wall module, i.e., a wall section without any openings. However, the building element can also be a window module with at least one window opening or a door module with at least one door opening. Door modules that have both a door opening and a window opening are also conceivable. Likewise, 23.01.2026

[0119] 27 Two door openings or two or more window openings may be provided. Accordingly, there is also a corresponding number of different wooden frames 1, which differ from one another by a different number of compartments 7. The number of compartments 7 is defined by the number of support beams 5 and by the number of wooden slats 6. In the example of Figure 1, the wooden frame 1 has several rows of compartments 58, in each of which several compartments 7 are arranged one above the other in the vertical direction H. In the example, four rows of compartments 58 are provided, each with five compartments 7 arranged one above the other. Preferably, in all variants, the dimensions of the compartments 7 are identical in the horizontal direction B and in the vertical direction H. In the example shown in Figure 1, all compartments have the same compartment height measured in the vertical direction H. Within each row of compartments 58, all compartments 7 have the same compartment width measured in the horizontal direction B.In this example, the compartments 7 of the two inner compartment rows 58 are wider than the compartments 7 of the two outer compartment rows 58. In Figure 1, the upper frame beam 30 and the lower frame beam 3u are labelled with "535" and "565" respectively, which can represent, purely as an example, a compartment width of the compartments 7 of the adjacent compartment row 58 in mm.

[0120] In the depth direction T, additional variants can be used, for example, for interior walls with a shallower depth and exterior walls with a greater depth. The timber frame 1 shown in Figure 1 can have the maximum number of timber beams 2 and timber rods 6. All other variants of the timber frame 1 then have fewer support beams 5 and / or fewer timber rods 6. For example, variants of the timber frame 1 are conceivable and can be manufactured that have only two support beams 5 instead of three, or only one support beam 5, or no support beam 5 at all, so that wall modules of different widths can be realized. At least one of the continuous support beams can also be omitted in window and door modules. 23.01.2026

[0121] 28 bars 5 can be omitted.

[0122] As shown in Figures 2 to 17, an assembly platform 11 comprises a base frame 12, which has a front face 13 for attaching the wooden beams 2. These wooden beams 2 then form the horizontal frame members 3, the vertical frame members 4, and the support beams 5 of the finished wooden frame 1. The base frame 12 defines a longitudinal direction X, a transverse direction Y, and a normal direction Z, all of which are perpendicular to each other. The longitudinal direction X and the transverse direction Y define an XY plane, to which the front face 13 of the frame extends parallel. The front face 13 of the frame faces away from a rear face 24 in the normal direction Z, which is perpendicular to the XY plane. In other words, the base frame 12 is configured at its front face 13 such that all the wooden beams 2 required for the construction of the wooden frame 1 can be attached to it.The assembly platform 11 is also equipped with a beam holder 14, which is configured for aligning and fixing the wooden beams 2 adjacent to the front 13 of the frame in predetermined positions. These predetermined positions are chosen such that the wooden beams 2 fixed in these positions form the horizontal frame members 3, the vertical frame members 4, and the support beams 5 of the finished wooden frame 1. The wooden beams 2 fixed in these predetermined positions can be fastened to one another, for example, by means of nails and / or screws. Furthermore, the assembly platform 11 is equipped with a rod guide 15, which is configured for aligning and guiding the wooden rods 6 when they are inserted through the openings 10 of the support beams 5 and into the end openings 9 of the respective vertical frame member 4.The wooden frame 1 can be assembled on the base frame 12 in either a standing or lying position. In the shown lying arrangement of the wooden frame 1 on the base frame 12, the vertical direction H coincides with the longitudinal direction X, and the horizontal direction B coincides with the transverse direction. 23.01.2026.

[0123] 29 tung Y and the depth direction T together with the normal direction Z.

[0124] Furthermore, the assembly platform 11 can be equipped with a lifting device 16, which allows the fully assembled wooden frame 1 to be adjusted relative to the front of the frame 13 such that the wooden frame 1 lifts off the front of the frame 13 in the depth direction T, to such an extent that it can be removed from the base frame 12 transversely to the depth direction T, i.e., in the height direction H and / or in the width direction B. For this purpose, the lifting device 16 can have at least one lifting beam 17 and a lifting drive 56 for adjusting the respective lifting beam 17 in the depth direction T relative to the base frame 12. The respective lifting beam 17 preferably extends in the longitudinal direction X at least along the entire length of the wooden frame 1, such that when the wooden frame 1 is lying down, the respective lifting beam 17 supports both horizontal frame beams 3.As can be seen particularly in Figure 2, several excavation beams 17, in this example four, running parallel to the longitudinal direction X, can be provided. These are connected to one another via several crossbeams 67, in this example four, running parallel to the transverse direction Y, to form a grid-like excavation structure 68, which can be adjusted as a unit by means of the lifting drive 56. The lifting drive 56 can adjust the respective excavation beam 17 or the excavation structure 68 between an assembly position shown at least in Figures 2 and 14 and a transfer position shown in Figure 15. In the assembly position, the respective excavation beam 17 or the excavation structure 68 is arranged on the front of the frame 13 such that the wooden beams 2 can be attached to, aligned with, and fixed to the front of the frame 13.In the handover position, the wooden frame 1 is lifted from the front of the frame 13 in the depth direction T to such an extent that it is free from the beam support 14 and the rod guide 15 and can be removed from the base frame 12 transversely to the depth direction T.

[0125] The base frame 12 is shown here on the front of the frame 13 on one side 18, 23.01.2026

[0126] 30, which is shown below in Figures 2 and 12 to 15, is also equipped with several retaining plates 65 and several support rods 66, which are fixedly attached to the base frame 12 and are adjacent to each other in the longitudinal direction X. The retaining plates 65 and the support rods 66 support the wooden frame 1 laterally, i.e., against one of the wooden beams 2. When the wooden frame 1 is mounted horizontally, it is supported by one of the vertical frame beams 4, e.g., by the left frame beam 41, against the retaining plates 65 and the support rods 66. The support rods 66 project in the normal direction Z beyond the retaining plates 65, the beam support 14, and the rod guide 15. An additional function of the retaining plates 65 and the support rods 66 is explained in more detail below with reference to Figures 14 and 15.

[0127] As shown in Figures 3 to 11, the beam support 14 has several pressure elements 19 and several abutment elements 20 on the front of the frame 13. The pressure elements 19 are adjustable between a locking position, shown in Figures 7 to 10, and a release position, shown in Figures 3 to 6. In Figure 6, the adjustment movement when moving the pressure elements 19 from the release position to the locking position is indicated by a rotation arrow 21. In the release position, the pressure elements 19 allow the wooden beams 2 to be placed against the front of the frame 13 and against the abutment elements 20. When moving from the release position to the locking position, the pressure elements 19 press the respective wooden beam 2 against the abutment elements 20, thereby aligning and locking the respective wooden beam 2 in the predetermined position on the base frame 12.When moving from the fixing position to the release position, the pressure elements 19 release the wooden beams 2, thereby enabling the mounted wooden frame 1 to be lifted from the base frame 12 in the depth direction T.

[0128] In figures 3 to 6, the pressure elements 19 are in the release position as of 23.01.2026

[0129] Figure 31. Subsequently, as shown in Figure 5, the wooden beams 2 can be attached to the front of the frame 13. As can be seen in Figure 5, one of the support beams 5 extends loosely between each pair of pressure element 19 and abutment element 20. The wooden frame 1 is expediently mounted lying down on the assembly platform 11, so that the support beams 5, which run vertically in the finished wooden frame 1 when mounted upright, are horizontally aligned on the assembly platform 11. After the wooden beams 2 are attached to the base frame 12, the pressure elements 20 are moved from the release position to the locking position. For this purpose, the beam holder 14 can expediently be configured so that all pressure elements 19 can be moved synchronously between the release position and the locking position. The pressure elements 19 are then in the locking position as shown in Figures 7 to 10.

[0130] For synchronous adjustment of the pressure elements 19, the beam support 14 can have a support linkage 22, shown only in rudimentary form in Figure 11, which is drive-connected to all pressure elements 19 of a pressure string running in the transverse direction Y of the base frame 12 or in the width direction B of the wooden frame 1. For example, the support linkage 22 can be coupled to the respective pressure element 19 via a drive lever 23. The beam support 14 also has a support drive (not shown here) which is drive-connected to the support linkage 22, so that the support drive allows all pressure elements 19 of the respective pressure string to be adjusted synchronously between the release position and the locking position via the support linkage 22. The support rod 22 is arranged on the rear side 24 of the base frame 12, facing away from the front side 13 of the frame.The base frame 12 can have a bearing plane 25 that extends parallel to the XY plane and is located between the front of the frame 13 and the rear of the frame 24, and on which the pressure elements 19 are rotatably mounted. The pressure elements 19 penetrate 23.01.2026.

[0131] 32 pressure elements 19 are connected to the bearing plane 25, such that they are drive-connected to the support linkage 22 at the rear of the frame 24. The pressure elements 19 are adjustable about a pivot axis 26 perpendicular to the bearing plane 25 between the release position and the locking position. The bearing plane 25 is advantageously formed by means of several bearing plates 27, one of which is shown by way of example in Figure 11. One of the pressure elements 19 is rotatably mounted on the bearing plate 27 shown. The bearing plate 27 also carries one of the abutment elements 20. The respective bearing plate 27 is attached to the base frame 12 in a suitable manner, in particular by being screwed to it.

[0132] Advantageously, the pressure elements 19 and the abutment elements 20 can be configured to align the vertical frame beams 4 and the vertical support beams 5 parallel to each other and to position them at a predetermined horizontal distance from one another. According to Figure 2, the beam support 14 can have an alignment device 59, which has a mobile alignment unit 60 on the front 13 of the frame. This mobile alignment unit is adjustable relative to the base frame 12 in the vertical direction H of the wooden frame 1 and in the longitudinal direction X of the base frame 12. A stationary alignment unit 61 is fixed to the base frame 12. The mobile alignment unit 60 can have several actuator units 62, which are distributed in the transverse direction Y and spaced apart from each other. Two such actuator units 62 are shown enlarged in Figures 16 and 17.In the example shown, each actuator unit 62 has three separate actuators 63 arranged adjacent to each other in the normal direction Z. Each actuator 63 can advantageously be configured as a pneumatic and / or hydraulic piston-cylinder unit, which is aligned in the longitudinal direction X and adjustable in length. The actuator 53 immediately adjacent to the front of the frame 13 extends a return rod 64, which is adjustable with the actuator 53 in the longitudinal direction X. According to Figure 17, a horizontal frame beam 3, e.g., the lower frame beam 3u in the area of ​​the mobile extension, is shown. 23.01.2026.

[0133] 33 alignment unit 60 placed on the front of the frame 13, such that the horizontal frame beam 3 is arranged between the actuators 63 of the respective actuator unit 62 and the respective return rod 64.

[0134] The alignment device 59 can now be configured to align the vertical frame beams 4 and the vertical support beams 5 relative to the horizontal frame beams 3. The mobile alignment unit 60, specifically by means of the actuators 63 of the actuator units 62, presses one horizontal frame beam 3, here the lower frame beam 3u, in the longitudinal direction X against the vertical frame beams 4 and against the vertical support beams 5, and presses these in the longitudinal direction X against the other horizontal frame beam 3. The other frame beam 3, here the upper frame beam 3o, is pressed in the longitudinal direction X against the stationary alignment unit 61, against which it then rests.

[0135] Aligning the vertical frame beams 4 and the vertical support beams 5 with respect to the horizontal frame beams 3 can advantageously be carried out while the pressure elements 19 are still in their release position. Alternatively, in another embodiment, the pressure elements 19, the abutment elements 20, and the alignment device 59 can be coordinated such that the alignment device 59 can align the vertical frame beams 4 and the vertical support beams 5 relative to the horizontal frame beams 3 even when the pressure elements 19 are in their locking position. The alignment device 59 then overcomes the holding force with which the pressure elements 19 press the vertical frame beams 4 and the vertical support beams 5 against the abutment elements 20 in the transverse direction Y in the longitudinal direction X.In other words, the pressure elements 19, together with the abutment elements 20, cause a transverse alignment, i.e., an alignment with respect to the transverse direction Y of 23.01.2026.

[0136] 34 vertical frame beams 4 and the vertical support beams 5, while the alignment device 59 effects a longitudinal alignment, i.e. an alignment with respect to the longitudinal direction X of the vertical frame beams 4 and the vertical support beams 5.

[0137] As shown in Figures 3 to 11, the rod guide 15 has several guide elements 28 for each wooden rod 6. The guide elements 28 are adjustable between a guide position, shown in Figures 7 to 10, and a release position, shown in Figures 3 to 6. For each wooden rod 6, the guide elements 28 have at least one guide contour 29 open transversely to the rod's longitudinal direction, through which the respective wooden rod 6 can be guided in its longitudinal direction. The rod guide 15 also has several closing elements 30, which are adjustable between a closed position and an open position. The closed position is shown in Figures 7 to 10, while the open position is shown in Figures 3 to 6. In the closed position, the closing elements 30 close the guide contours 29 of the guide elements 28, which are adjusted to the guide position, transversely to the rod's longitudinal direction.In the open position, the locking elements 30 open the guide contours 29 of the guide elements 28 transversely to the longitudinal direction of the rod. In other words, the guide contours 29 have an opening transversely to the longitudinal direction of the rod, which can be opened and closed by means of the locking elements 30. The guide elements 28 and the locking elements 30 are coordinated with each other such that, in the guided position of the guide elements 28 and in the closed position of the locking elements 30, the guide contours 29 are aligned in the lateral direction B congruently with the through openings 10 and the end openings 9 of the support beams 5 and vertical frame beams 4, which are aligned and fixed to the front 13 of the frame, so that the wooden rods 6 are held in the guide contours 29 transversely to the lateral direction B, i.e., transversely to the longitudinal direction of the rod, and guided in the longitudinal direction. In the guided position, 23.01.2026.

[0138] 35 The guide contours 29 in the longitudinal direction and in the width direction B of the wooden frame 1 provide a passage for the wooden bars 6 for aligning and guiding the wooden bars 6, which facilitates the insertion of the wooden bars 6 into the passage openings 10 or into the end openings 9. In the release position of the guide elements 28, the guide contours 29 are arranged outside the respective wooden bar 6, so that they release the respective wooden bar 6 in the depth direction T. Consequently, the assembled wooden frame 1 can be lifted off the base frame 12 in the depth direction T. When the wooden beams 2 are attached to the base frame 12, the guide elements 28 are in the release position and the locking elements 30 are in the open position, as shown in Figures 3 to 6.To align and fix the wooden beams 2 to the base frame 12, the pressure elements 19 are moved from the release position to the fixing position according to the rotation arrow 21, as shown in Figure 6. Simultaneously, the guide elements 28 are moved from the release position to the guide position, and the locking elements 30 are moved from the open position to the closed position, as indicated by further rotation arrows 31 in Figure 6. The guide contours 29 are then aligned with the through-openings 10 and closed transversely to the longitudinal direction of the bars. This state is shown in Figures 7 to 11. In Figures 7 and 8, the wooden beams 2 are positioned and fixed, and the wooden rods 6 are guided through the through-openings 10 of the support beam 5 shown in Figure 7. In Figures 9 and 10, the wooden rods 6 are secured in the guide contours 29 by the locking elements 30.Figure 10 shows a configuration in which, in this example, three wooden rods 6 are each guided through one of the through-openings 10 of the support beam 5. The rod guide 15 can advantageously be configured to adjust all locking elements 30 synchronously between the open and closed positions. For this purpose, the rod guide 15 can have a guide linkage 32, shown only in rudimentary form in Figure 11, which is drive-connected to all locking elements 30. The rod guide 15 can also have a guide (not shown here). 23.01.2026.

[0139] 36 drive, which is connected to the guide linkage 32 drive.

[0140] The guide drive allows all locking elements 30 to be adjusted synchronously between the open and closed positions via the guide rod 32. The guide rod 32 can be coupled to the respective locking element 30 via a drive lever 33. Here, too, it is advantageous for the guide rod 32 to be arranged on the rear of the frame 24. Furthermore, the locking elements 30 can be rotatably mounted on the support plane 25, and in particular on the bearing plate 27, about a pivot axis 34 extending perpendicular to the support plane 25. The locking elements 30 penetrate the support plane 25 and are coupled to the guide rod 32 on the rear of the frame 24. In the example shown in Figure 11, two locking elements 30 are rotatably mounted on the bearing plate 27.According to Figures 4, 6, 8, 10, and 11, the respective guide element 28 can have two or more guide contours 29 that are spaced apart from each other in the depth direction T and are all open on the same side. The respective closing element 30 is also configured such that, in the closed position, it closes the two or more guide contours 29 of the respective guide element 28 transversely to the longitudinal direction of the rod, and in the open position, it opens the two or more guide contours 29 transversely to the longitudinal direction of the rod. This makes it possible, firstly, to align and guide at least two wooden rods 6 simultaneously, as shown in Figure 10. Secondly, it makes it possible to provide different distances in the depth direction T for wooden rods 6 arranged in pairs, which is particularly advantageous when wooden frames 1 with different depths are to be manufactured.For example, the respective guide element 28 can have three or more guide contours 29, which allows two or more different distances in the depth direction T to be set for pairs of wooden rods 6.

[0141] In the particularly advantageous embodiment presented here, the leading- 23.01.2026

[0142] 37. The guide elements 28 of the rod guide 15 are formed by the pressure elements 19 and the abutment elements 20 of the beam support 14. In other words, the guide contours 29 of the guide elements 28 are formed on the pressure elements 19 and on the abutment elements 20 such that the fixed position of the pressure elements 19 corresponds to the guide position of the guide elements 28. Accordingly, the abutment elements 20 are also mounted so as to be rotatable about a pivot axis 35 extending perpendicular to the bearing plane 25 in order to realize the guide position and the release position for the function as a guide element 28, wherein the respective abutment element 20 fulfills the function as an abutment element 20 in the guide position, in the release position and in any intermediate position, against which the respective wooden beam 2 is pressed by means of the respective pressure element 19 for alignment. Accordingly, the closing elements 30 form first closing elements 30.1, which interact with the guide contours 29 of the pressure elements 19, and second closing elements 30.2, which interact with the guide contours 29 of the abutment elements 20. According to Figure 11, the rod guide 15 can also optionally be configured to adjust the guide contours 29 of the guide elements 28 formed on the abutment elements 20 synchronously between the guide position and the release position. For this purpose, the rod guide 15 can have a linkage 69, shown only in rudimentary form in Figure 11, which is drive-connected to all abutment elements 20. The rod guide 15 can also have a drive (not shown here) which is drive-connected to the linkage 69. This drive allows all abutment elements 20 to be adjusted synchronously between the release position and the guide position via the linkage 69.The linkage 69 can be coupled to the respective abutment element 20 via a drive lever 70. Here too, it is advantageous for the linkage 69 to be arranged on the rear side 24 of the frame. Furthermore, the abutment elements 20 can be attached to the support plane 25 and, in particular, to the La- 23.01.2026.

[0143] The 38 plate 27 is mounted so as to be rotatably adjustable about the axis of rotation 35, which extends perpendicular to the plane 25. The abutment elements 20 penetrate the plane 25 and are coupled to the linkage 69 at the rear 24 of the frame.

[0144] The pressure elements 19, equipped with guide contours 29, are also adjustable to an intermediate position between the locking position and the release position, in which the wooden beams 2 are released in the depth direction T, but the wooden rods 6 are still held in the depth direction T by the guide contours 29. Additionally or alternatively, the abutment elements 20, also equipped with guide contours 29, can be adjusted to an intermediate position between the guide position and the release position, in which the wooden rods 6 are held in the depth direction T by the guide contours 29. Advantageously, the pressure elements 19 and the abutment elements 20 are coupled to the support linkage 22 so that they can be adjusted synchronously by the support drive. As shown in Figure 6, the rotational adjustment of the pressure elements 19 and the abutment elements 20 occurs in the same direction of rotation.In contrast, the associated locking elements 30, namely the first locking element 30.1 and the second locking element 30.2, are adjusted with opposite directions of rotation. Here too, the adjustment of the locking elements 30 can be synchronous.

[0145] As shown in Figures 12 to 15, an assembly station 36, configured for assembling wooden frames 1 for building components, comprises at least one assembly platform 11 and at least one assembly robot 37. In the example shown here, the respective assembly station 36 has two assembly platforms 11 and two assembly robots 37. The assembly robots 37 are configured for positioning the wooden beams 2, for fastening the wooden beams 2 to one another, for inserting the wooden rods 6, and for fastening the wooden rods 6 to the wooden beams 2. 23.01.2026

[0146] 39 guriert. The two assembly platforms 11 form a first assembly platform 11.1 and a second assembly platform 11.2 within assembly station 36. The two assembly robots 37 of assembly station 36 form a first assembly robot 37.1 and a second assembly robot 37.2.

[0147] Within the assembly station 36, the respective assembly platform 11 is arranged such that the front of the frame 13 lies in an assembly plane 38, which is inclined relative to a vertical direction 39 and has an angle of inclination 40. The assembly plane 38, the vertical direction 39, and the angle of inclination 40 are indicated by way of example in Figure 12. The angle of inclination 40 is greater than 0°. In other words, the assembly plane 38 is not vertically oriented, but inclined relative to the vertical direction 39. The angle of inclination 40 has a maximum of 45° and is approximately 10° in the example shown.

[0148] The assembly platform 11 is arranged in the assembly station 36 such that the respective wooden frame 1 is mounted horizontally. In other words, the wooden frame is mounted lying down on the left frame beam 4I or on the right frame beam 4r. Compared to the upright arrangement according to Figure 1, the horizontal wooden frame 1 is rotated by 90° about an axis of rotation parallel to the depth direction T. When mounted horizontally, the width direction B of the wooden frame 1 extends vertically in the assembly station 36, while the height direction H of the wooden frame 1 is oriented horizontally in the assembly station 36.

[0149] The assembly station 36 can also be equipped with a bogie 41 to which the two assembly platforms 11 are attached. The bogie 41 is rotatable about a vertical axis of rotation 53 by at least 180°, preferably by 360°, and in particular continuously. The bogie 41 is arranged between the two assembly robots 37. 23.01.2026

[0150] 40

[0151] The assembly station 36 can also be equipped with an assembly controller 42, which is coupled via corresponding control lines (not shown here) to the bogie 41, the two assembly platforms 11, and the two assembly robots 37, so that the assembly controller 42 can control and operate the bogie 41, the two assembly stations 11, and the two assembly robots 37. The assembly controller 42 is configured to carry out a four-stage process 43, which is shown in Figure 18 in the form of a flowchart.

[0152] In a first step 44 of the four-step process 43, the first assembly robot 37.1, in particular, attaches the upper frame beam 30, the lower frame beam 3u, the support beams 5, and, in a preferred configuration, the left frame beam 4I or the right frame beam 4r to the respective assembly platform 11. In other words, in this configuration, only one of the vertical frame beams 4 is mounted, while the other vertical frame beam 4 is not. In this configuration, the vertical frame beams 4 have end openings 9 designed as blind holes, so that the longitudinal ends of the wooden rods 6 can only be inserted into them, but not passed through them. In an alternative second configuration, at least one of the two vertical frame beams 4 can have end openings 9 designed as through openings, so that the wooden rods 6 can be passed through these end openings 10.In this second configuration, in the first cycle 44 both vertical frame beams 4, i.e. ultimately all wooden beams 2, can be attached to the respective mounting platform 11.

[0153] In a second step 45 of the four-step process 43, the wooden rods 6 are expediently guided through the through-openings 10 of the support beams 5 using the second assembly robot 37.2 and inserted into the end openings 9 of one 23.01.2026

[0154] 41

[0155] Frame beam 4 of left and right frame beam 4I, 4r are inserted. In the second configuration, the wooden rods 6 can be passed through the end openings 9 of the other vertical frame beam 4, which are designed as through openings.

[0156] In a third step 46 of the four-step process 43, the missing vertical frame beam 4, or the last wooden beam 2, can be attached in the first configuration, positioned against the two horizontal frame beams 3. The remaining free longitudinal ends of the wooden rods 6 are inserted into the end openings 9 of this vertical frame beam 4. This can advantageously be performed again with the first assembly robot 37.1. In the third step 46, the wooden beams 2 are also fastened together. This, too, can preferably be performed with the first assembly robot 37.1. Optionally, the respective assembly robot 37, here the first assembly robot 37.1, can be additionally equipped with a hold-down device with which two wooden beams 2, which are to be joined at a joint and fastened together, are positioned flush with each other in the depth direction T and then fastened together.In the initial configuration, it may be advantageous to fasten all other wooden beams 2 together before attaching the last, missing vertical frame beam 4. To attach the last wooden beam 2, the beam holder 14 and the rod guide 15 can be moved to the intermediate positions described above, in which the fixing of the wooden beams 2 is released while the guidance of the wooden rods 6 is maintained. This allows the missing wooden beam 2 to be easily attached, such that the rod ends can be inserted into the end openings 9 of this wooden beam 2. After the last wooden beam 2 has been positioned, the beam holder 14 and the rod guide 15 are moved back to the fixing position and the guiding position, respectively, thereby finally aligning and positioning the last wooden beam 2. 23.01.2026.

[0157] 42 is ionized. Subsequently, the last mounted vertical frame beam 4 can also be attached to the two horizontal frame beams 3.

[0158] In a fourth step 47 of the four-step process 43, the wooden rods 6 can be attached to the wooden beams 2, in particular by means of the second assembly robot 37.2. Furthermore, in the fourth step 47, the fully assembled wooden frame 1 is removed from the respective assembly platform 11.

[0159] After completion of the fourth bar 47, the four-bar process 43 begins again with the first bar 44 to assemble the next wooden frame 1 .

[0160] The assembly control 42 can be configured to carry out an assembly process 48, which is simplified in the form of a flowchart in Figure 19. The assembly process 48 comprises four assembly steps or work steps 49, 50, 51, 52, which follow one another and are repeated. The assembly process 48 is configured such that, in the assembly station 36, two wooden frames 1 are manufactured or assembled simultaneously in the four consecutive assembly steps 49, 50, 51, 52 according to the four-stage process 43, but offset from each other by one stage. For this purpose, the assembly control 42 can move the bogie 41 into a first rotation position, which is shown in Figures 12 and 13, and in which the first assembly platform 11.1 faces the first assembly robot 37.1, while the second assembly platform 11.2 faces the second assembly robot 37.2.In a second rotational position of the bogie 41 (not shown here), which is rotated 180° about the axis of rotation 53 relative to the first rotational position, the first assembly platform 11.1 faces the second assembly robot 37.2, while the second assembly platform 11.2 faces the first assembly robot 37.1. The first assembly robot 37.1 is configured to operate according to the first cycle 44 and the third cycle 46. In contrast, the second assembly robot 37.2 is configured as follows: 23.01.2026.

[0161] 43 guriert that he can work according to the second bar 45 and according to the fourth bar 47.

[0162] In the first work step 49, the first rotation position is present, and the first assembly robot 37.1 works on the first assembly platform 11.1 according to the first cycle 44, attaching the wooden beams 2. The second assembly robot 37.2 works on the second assembly platform 11.2 according to the fourth cycle 47, attaching the wooden rods 6 to the wooden beams 2. Furthermore, according to the fourth cycle 47, finished wooden frames 1 are removed from the second assembly platform 11.2 and transported away. The removal of the finished wooden frame 1 is indicated by an arrow 54 in Figures 12 and 13. It can be seen that the finished wooden frame 1 is transported lying down.

[0163] In the second work step 50, the second rotation position is present, and the first assembly robot 37.1 works on the second assembly platform 11.2 according to the first cycle 44, so that the wooden beams 2 are arranged on the second assembly platform 11.2. The second assembly robot 37.2 now works on the first assembly platform 11.1 according to the second cycle 45 and inserts the wooden rods 6.

[0164] In the third work step 51, the first rotation position is again present, and the first assembly robot 37.1 works on the first assembly platform 11.1 according to the third cycle 46 and can, if necessary, attach the missing wooden beam 2 and fasten the wooden beams 2 together. Simultaneously, the second assembly robot 37.2 works on the second assembly platform 11.2 according to the second cycle 45 and inserts the wooden rods 6 there.

[0165] In the fourth work step 52, the second rotation position is again present and the first assembly robot 37.1 works on the second assembly platform 11.2 according to 23.01.2026

[0166] 44, the third bar 46, so that it attaches the missing wooden beam 2 there if necessary and fastens the wooden beams 2 together. The second assembly robot 37.2 then works on the first assembly platform 11.1 according to the fourth bar 47 and attaches the wooden rods 6 to the wooden beams 2. In addition, according to the fourth bar 47, the finished wooden frame 1 is removed from the first assembly platform 11.1 and transported away according to arrow 54.

[0167] After the fourth work step 52, the first work step 49 follows again and the work process 48 is repeated.

[0168] The removal of the fully assembled wooden frame 1 from the respective assembly platform 11, carried out in the fourth bar 47, is explained in more detail below with reference to figures 14 and 15.

[0169] In the state shown in Figure 14, the wooden frame 1 facing the viewer is fully assembled, so that it can be removed from the respective base frame 12. In Figure 14, the respective excavation beam 17 or excavation structure 68 is still in the assembly position in which the beam support 14 and the rod guide 15 prevent the wooden frame 1 from shifting transversely to its depth direction T relative to the base frame 12. The finished wooden frame 1 is supported at the bottom, i.e., at the edge 18, by the retaining plates 65 and the support rods 66.

[0170] To remove the finished timber frame 1, the excavation beams 17 or the excavation structure 68 are first moved from their assembly position according to Figure 14 to their transfer position according to Figure 15, in which they move relative to the base frame 12 in the depth direction T and accordingly lift the timber frame 1 from the base frame 12 in the depth direction T. In Figure 15, the timber frame 1 is lifted from the base frame 12 to such an extent that it is free from the beam support 14 and from the rod guide 15. The timber frame 1 is shown on January 23, 2026.

[0171] 45 is also free from the retaining plates 65, while it still rests on the support rods 66. The lifting of the wooden frame 1 from the base frame 12 is indicated in Figure 15 by an arrow 55.

[0172] Following this, the finished wooden frame 1 can be transferred directly to a conveying device 57, which is indicated by a line in Figures 12 to 15 and which allows the finished wooden frame 1 to be removed from the assembly platform 36 in the direction of an arrow 54. The support rods 66 simplify the transfer of the finished wooden frame 1, lifted from the base frame 12, to the conveying device 57. The support rods 66 can be configured to rotate about their longitudinal axis to further facilitate the transfer.

[0173] Several support rods 66, arranged parallel to one another, support the wooden frame 1 on its underside. All support rods 66 are configured to rotate about their longitudinal axis and can be driven by a common drive unit 70. The drive unit 70 comprises an electric drive motor 71 and a chain drive 72 in the form of a drive chain, which rotates all support rods 66. At one end of each support rod 66 is a non-rotatably arranged toothed ring 73, into which the drive chain 72 engages.
