Description

[0001] The present invention relates to a woodworking device for processing round timber aligned along a longitudinal direction of the woodworking device, comprising a machine frame, a processing portal mounted on the machine frame so as to be movable at least in the longitudinal direction, and a holding device arranged on the machine frame for holding the round timber on the machine frame. The present invention also relates to a woodworking system with such a woodworking device and a method for processing round timber.

[0002] Examples of woodworking devices are disclosed in documents WO 2018 / 190731 A1, US 5,806,401, ES 2 382 858 A1, US 5,109,899, WO 2020 / 079513 A1, CA 2,300,037 A1 and US 2019 / 0047170 A1. Document CA 2,300,037 A1 discloses a woodworking device according to the preamble of claim 1 and a method according to the preamble of claim 15.

[0003] Wood has been used as a material for manufacturing objects in a wide variety of ways since time immemorial. The processing of wood has constantly evolved. Nowadays, trees are felled with large machines and immediately processed into logs. These logs are then delivered by truck to sawmills, where the desired boards are produced from the logs through debarking, edging, cutting, and splitting. Such sawmills typically employ large machines, each performing one of these processing steps.

[0004] Such sawmills have several major disadvantages: They require a large amount of space because large quantities of wood must be stored after each processing step. Transportation costs are high, as the processed wood must be moved between the individual stations. Staffing requirements are high, as many different machines and transport vehicles must be operated separately. Finally, recent months have shown that sawmills hold a near-monopoly and can therefore arbitrarily dictate the price of sawn boards in the event of raw material shortages. This results in incalculable price risks for timber construction companies and end consumers.

[0005] The object of the present invention is therefore to create an improved woodworking device. In particular, the disadvantages mentioned above are to be overcome. Above all, the woodworking device should enable the production of sawn wooden boards in a space-saving, efficient, and fast manner, and as independently as possible from sawmills.

[0006] This is achieved by a woodworking device with the features of claim 1. According to the invention, the woodworking device comprises an edging device arranged on the processing portal for edging the round timber, wherein the edging device has at least one milling head. Furthermore, the woodworking device comprises a cutting device arranged on the processing portal for cutting the round timber, wherein the cutting device has at least one horizontally oriented saw. Finally, the woodworking device comprises a splitting device arranged on the processing portal for splitting the round timber, wherein the splitting device has at least one vertically oriented saw.

[0007] The woodworking machine therefore has a processing portal, on which the edging device, the cutting device, and the splitting device are arranged. Thus, the processed wood no longer needs to be laboriously transported back and forth between the individual processing stations and stored temporarily; instead, at least three processing steps can be carried out in a single processing portal.

[0008] In other words, the log remains clamped to the same machine frame via the holding device throughout, while the edging, cutting and splitting of the entire log into individual wooden boards is carried out completely.

[0009] The present invention provides a largely automated and labor-saving manufacturing method for wooden boards directly from round timber.

[0010] Preferred embodiments of the present invention are set out in the dependent claims.

[0011] To enable automation, a first scanning device for scanning the round timber is preferably provided.

[0012] According to a preferred embodiment, the first scanning device is designed to detect the dimensions of the round timber. In particular, this first scanning device detects the (minimum) diameter of the round timber. The length of the round timber can also be detected.

[0013] To enable safe, stable and consistent processing, it is preferably provided that the holding device has at least two holding jaws, wherein the holding jaws engage substantially centrally on opposite end faces of the round timber in a holding position.

[0014] It is particularly preferred that the round timber is rotatably mounted on the machine frame via the holding device, preferably in 90° increments.

[0015] Specifically, the holding device has at least one drive motor through which the rotation relative to the machine frame is carried out.

[0016] Preferably, guide rails are arranged on the machine frame, with the machining portal being mounted on the guide rails via rollers.

[0017] Preferably, the guide rails run straight and parallel to the longitudinal direction of the woodworking device.

[0018] The terms "horizontal," "vertical," "front," and "back" used herein refer to the installed state of the woodworking jig when the log is horizontally oriented during processing (and thus the longitudinal direction of the woodworking jig is aligned). If the woodworking jig is tilted or even vertically oriented during processing, the meaning of these terms changes accordingly.

[0019] The edging device should be designed to allow for simple and quick edging of the round timber. Preferably, the at least one milling head is mounted on the machining portal so that it can be rotatably and – preferably perpendicular to the longitudinal direction – linearly displaced.

[0020] Additionally, it may be provided that at least one milling head is mounted on the machining portal so as to be linearly displaceable in the horizontal direction. However, it is preferred that the holding device is mounted so as to be linearly displaceable in the vertical direction relative to the machining portal and its trimming device.

[0021] It may be provided that the trimming device has a drive motor arranged on the machining portal for at least one milling head of the trimming device.

[0022] According to a preferred embodiment, the trimming device has at least three milling heads rotatable about a vertical axis of rotation. Preferably, each milling head is assigned its own drive motor.

[0023] According to one embodiment, four milling heads can be provided. Specifically, two of the four milling heads can be arranged longitudinally in front of the cutting device, and two of the four milling heads can be arranged longitudinally behind the cutting device. With the two milling heads arranged on each side, it is possible – as with the splitting device – to carry out edging (from both sides of a wooden board), depending on the direction of movement.

[0024] The cutting device should be designed to allow cutting of the round timber. Preferably, the at least one horizontally oriented saw of the cutting device is mounted on the processing portal so as to be linearly displaceable, preferably in the vertical direction. Alternatively (or additionally), the holding device can be mounted so as to be linearly displaceable, preferably in the vertical direction, relative to the processing portal and its cutting device. This allows the different layers to be cut out of the round timber.

[0025] Furthermore, it is preferably provided that at least one horizontally oriented saw of the cutting device is designed in the form of a circular saw or a band saw.

[0026] If the saw of the cutting device is designed as a band saw, it is preferably provided that this band saw has two cutting areas (aligned perpendicular to the longitudinal axis) on both opposite longitudinal sides of the saw blade. Thus, the round timber can be cut both when moving forward and when moving backward along the longitudinal axis.

[0027] Alternatively, the cutting device can be designed with two horizontally oriented circular saws arranged one behind the other in the longitudinal direction, with the two horizontally oriented circular saws positioned offset to each other when viewed perpendicular to the longitudinal direction. With these two circular saws, it is possible to cut the log from both sides simultaneously. Therefore, very large circular saws are not required; it is sufficient for the radius of the circular saw to be larger than the maximum radius of the log being processed.

[0028] Furthermore, it is preferably provided that the cutting device has a drive motor arranged on the machining portal for at least one saw of the cutting device.

[0029] The splitting device should be designed to allow for simple and quick splitting of the logs. Preferably, the at least one vertically oriented saw is mounted on the processing portal so that it can be rotated and, preferably, linearly displaced in the horizontal direction.

[0030] According to a preferred embodiment, the at least one vertically oriented saw of the splitting device is designed in the form of a circular saw.

[0031] The size of this circular saw should be chosen so that the radius of the circular saw is larger than the maximum board thickness to be produced.

[0032] Furthermore, it is preferably provided that the splitting device has a drive motor arranged on the machining portal for at least one saw of the splitting device.

[0033] For efficient processing, one embodiment provides that the splitting device has two vertically oriented saws arranged one behind the other in the longitudinal direction, with the two vertically oriented saws being offset side by side when viewed transversely to the longitudinal direction. This allows the log to be split into three adjacent wooden boards.

[0034] Furthermore, it is preferably provided that one of the two vertically oriented saws of the splitting device is arranged longitudinally in front of the cutting device and the other of the two vertically oriented saws of the splitting device is arranged longitudinally behind the cutting device.

[0035] This allows the splitting device, positioned in front of the cutting device in the direction of movement of the processing portal, to split the log before cutting. Once the processing portal has moved completely along the log and at least one board has been cut, the processing portal moves in the opposite direction, at which point the other of the two vertically oriented saws is positioned in front of the cutting device in the direction of movement and splits the log.

[0036] After the trimming, cutting and splitting has been carried out, it is also important to transport and sort the wooden boards produced in this way as quickly as possible.

[0037] Therefore, a sorting system for sorting the wooden boards is particularly preferred.

[0038] To move the cut wooden board away from the rest of the round timber, it is preferably provided that the sorting system has a first, preferably stationary, transport device for transporting wooden boards cut from the round timber.

[0039] The first transport device can, in principle, have a gripper, preferably in the form of pincers. Preferably, the first transport device is designed as a handling robot, preferably equipped with a vacuum suction cup.

[0040] To guarantee compact and safe manufacturing, a housing, preferably lockable, for the machine frame including the machining portal is preferably provided.

[0041] The first transport device is also preferably arranged within the housing.

[0042] Furthermore, it is preferably provided that the sorting system includes a second, preferably mobile, transport device for transporting, sorting, and stacking the wooden boards. This allows the wooden boards to be immediately and correctly assigned to a stack with boards of (virtually) identical size.

[0043] In order to automate this sorting process as well, it is preferably provided that the sorting system has a second scanning device for scanning the wooden boards cut from the round timber.

[0044] Preferably, the second scanning device should be able to record the dimensions of the wooden boards and / or the board qualities.

[0045] According to a preferred embodiment, the holding device has at least two clamping elements, separate from the holding jaws, for holding the round timber via its outer surfaces.

[0046] This makes it possible for the holding device to grip the side boards after cutting and hold the log (or the area remaining for the main product) laterally in such a way that the main product can also be completely cut without having to remove the processed log from the holding device.

[0047] For automation, it is particularly crucial that a control or regulating unit is provided to control or regulate the woodworking device.

[0048] This control unit can be connected to or be an integral part of an operating device, allowing an operator to operate and control the woodworking machine via a corresponding control program and menu. Such an operating device can include a screen and a keyboard, preferably a touchscreen.

[0049] It is preferably provided that a large number of log cutting patterns are stored in the memory of the control unit, with each log cutting pattern corresponding to a specific diameter of the log detected by the first scanning device. This makes it possible to ideally match the log cutting pattern to the actual dimensions of the log in question. The log cutting pattern should be designed or selected in such a way as to minimize waste and ensure the highest possible quality of the individual boards. An entire library of different log cutting patterns can be stored.

[0050] It is particularly preferred that the machining portal and the devices arranged on the machining portal, namely the edging device, cutting device and splitting device, are movable and operable depending on the log cutting pattern corresponding to the detected diameter.

[0051] This means that trimming, cutting and splitting can be carried out fully automatically and quickly with a single processing portal.

[0052] Protection is also sought for a woodworking plant with a woodworking device according to the invention.

[0053] To provide an efficient wood processing plant that takes over all the tasks of a conventional sawmill, it is preferably intended that the wood processing plant, in addition to the wood processing equipment, includes a feed area for supplying round timber and / or a debarking device for debarking the supplied round timber and / or a chip drying device and / or a chip compaction device and / or a chip container and / or a storage area for stacked boards. Of course, further stations and devices may also be included.

[0054] The object of the present invention is also achieved by a method according to claim 15. Such a method for processing round timber, which is aligned along a longitudinal direction of a woodworking device, comprises the following steps: Holding the log via a holding device on a machine frame, moving a processing portal longitudinally on the machine frame, wherein the following steps are carried out during this movement of the processing portal: trimming the log by an edging device arranged on the processing portal, wherein the edging device has at least one milling head (whereby preferably the at least one milling head is rotatably and - preferably perpendicular to the longitudinal direction - linearly displaceable on the processing portal), cutting the log by a cutting device arranged on the processing portal, wherein the cutting device has at least one horizontally oriented saw (whereby preferably the at least one horizontally oriented saw is rotatably and, preferably in the vertical direction, linearly displaceable on the processing portal), and splitting the log by a splitting device arranged on the processing portal.wherein the splitting device has at least one vertically oriented saw, (whereby the at least one vertically oriented saw is preferably rotatably and preferably linearly displaceable in the horizontal direction on the machining portal).

[0055] In this process, it is preferable to debark the log in a debarking device before it is held over the holding device. The debarking device can also be arranged on the machine frame.

[0056] Furthermore, it is preferably provided that during edging, the holding device holds the log via the holding jaws gripping the end faces, and after the log has been completely edged, the holding device is reconfigured so that it holds the log by at least two gripping elements separate from the holding jaws, holding it against its outer surfaces. This allows the entire main product to be cut in a single pass.

[0057] Further details and advantages of the present invention are explained in more detail below with reference to the description of the figures and the exemplary embodiments illustrated in the drawings. These show: Fig. 1 schematically shows a woodworking plant with a woodworking device in a top view, Fig. 2 schematically shows a woodworking plant with a woodworking device in a side view, Figs. 3-14 show three-dimensional views from a low angle of the various steps of processing the round timber with the woodworking device, Figs. 15 and 16 show views of a debarking device including the feed area, Fig. 17 a perspective view of a specific embodiment of the woodworking device including the sorting system, Fig. 18 a view of the woodworking device including the sorting system, and Figs. 19-25 various views of the woodworking device including the sorting system in different positions.

[0058] In Fig. 1 A schematic diagram of a wood processing plant 18 is shown. Such a wood processing plant 18 can be set up on the premises of a carpentry company, meaning it can be located practically anywhere. A preferred location – especially to minimize transport distances – is, for example, in the immediate vicinity of a production hall for prefabricated wood components (wooden walls, etc.). Such a wood processing plant 18 requires a footprint of only about 500 m², while achieving an annual output of approximately 25,000 cubic meters (in single-shift operation). In contrast, conventional sawmills require a footprint of approximately 20,000 m² to achieve an output of roughly the same quantity.

[0059] In order to achieve all the basic functions and manufacturing processes as in a sawmill, the wood processing plant 18 comprises, in addition to the wood processing device 1 (including sorting system 10), the following components or stations: a feed area 19 for feeding round timber H, a debarking device 20 for debarking the fed round timber H, optionally a chip drying device 21, optionally a chip compaction device 22, optionally a chip container 23 and / or a storage area 24 for stacked boards P.

[0060] The arrangement of the individual stations is arbitrary in itself, as long as an efficient way of working is possible and should be adapted to the available space.

[0061] For the present invention, the woodworking device 1 is the essential component or station. Fig. 2 This woodworking device 1 is shown schematically in a side view.

[0062] The left section again shows the feed area 19 for round timber H. This can be designed like a known feed area 19, for example with rollers.

[0063] The woodworking device 1 has a housing 13, preferably lockable, for the machine frame 2 including the processing portal 3. Before the log H is held in the processing portal 3, it can pass through a first scanning device 8 to scan the log H. The dimensions MH of the log H can be recorded with this first scanning device 8.

[0064] The woodworking device 1 has a holding device 4, an edging device 5, a cutting device 6 and a splitting device 7, these devices will be discussed in detail later.

[0065] Furthermore, the woodworking device 1 includes a sorting system 10 for sorting the wooden boards B cut from the log H. This sorting system 10 has a first transport device 11 (for example in the form of a handling robot with vacuum suction cups) for transporting wooden boards B cut from the log H.

[0066] The woodworking device 1, preferably its sorting unit 10, can have a second scanning device 9 for scanning the wooden boards B cut from the round timber H. With this second scanning device 9, the dimensions MB of the wooden boards B and / or the board qualities can be recorded.

[0067] The sorting system 10 can also include a second, preferably mobile, transport device 12 for transporting, sorting, and stacking the wooden boards B. These wooden boards B can then be stored on a stack of boards P in a storage area 24.

[0068] A control unit 17 is also provided for controlling the woodworking device 1. A multitude of log cutting patterns Hcut are stored in a memory of the control unit 17, each log cutting pattern Hcut corresponding to a specific diameter or dimension MH of the log H detected by the first scanning device 8. The control unit 17 is connected to the scanning device 8 via a signal connection. Depending on the configuration, the remaining components of the woodworking device 1 can also be controlled or regulated via the control unit 17.

[0069] In the Fig. 3 bis 14 A log H is shown in a three-dimensional, obliquely frontal view. Some components of the woodworking device 1 are hidden, so that only the milling heads 5.1, 5.2, 5.3, and 5.4 of the edging device 5, the saws 6.1 and 6.2 of the cutting device 6, and the saws 7.1 and 7.2 of the splitting device 7 are shown. A specific log cutting pattern H cut is schematically drawn into the log H, which is digitally fitted to the log H based on a previously recorded measurement of the log's dimensions MH. Thus, the Fig. 3 bis 14 only a kind of preliminary visualization of the shape in which the individual wooden boards B are to be cut out of the round timber H, which is still in one piece.

[0070] In Fig. 3 The first step of the machining process now takes place. For this, the devices mounted on the machining portal 3 (not shown) – the edging device 5, the cutting device 6, and the splitting device 7 – are moved longitudinally L along the machine frame 2 (not shown). This movement occurs from back to front, but can of course also be reversed. The two milling heads 5.1 and 5.2 mill off the top section of the log H. This flattens the debarked tree.

[0071] In Fig. 4 The first step is already complete and the "top layer" has been completely milled away. Now, in the second step, the machining portal 3, along with the fixtures 5, 6 and 7 attached to it, moves back again.

[0072] Before this reverse movement begins, the milling heads 5.1 and 5.2 move away from each other, or rather, each moves perpendicular to the longitudinal axis L relative to the machining portal 3. In contrast, the milling heads 5.3 and 5.4 perform the opposite movement relative to each other. This is possible because at least one milling head 5.1, 5.2, 5.3 and / or 5.4 of the trimming device 5 is rotatably mounted on the machining portal 3 and is linearly displaceable – at least in the horizontal direction perpendicular to the longitudinal direction L.

[0073] Before the machining portal 3 moves backward, a vertical relative movement also takes place between the devices 5, 6 and 7 and the round timber H. For this purpose, the devices 5, 6 and 7 can either be moved vertically (downwards) relative to the machining portal 3, or the entire machining portal 3 is moved vertically (downwards) relative to the machine frame 2 including the log H, or the log H is moved vertically (upwards) relative to the machining portal 3.

[0074] The height and horizontal adjustment of the individual processing elements (milling heads and saws) is carried out by the control unit 17 depending on the specified round timber cutting pattern H cut. The position of the respective processing elements is adjusted before each new backward or forward movement of the processing portal 3 along the machine frame 2.

[0075] When moving the edging device 5 backwards along the round timber H, edging is carried out according to Fig. 4 The milling heads 5.3 and 5.4, now positioned closer together and at the front, cut the (new) uppermost layer of the round timber H. The milling heads 5.3 and 5.4 thus create the two lateral surfaces of the... Fig. 4 The top wooden board 4. Simultaneously, saws 6.1 and 6.2 cut the round timber H, so that the top wooden board B separates from the round timber H. Saws 6.1 and 6.2 thus create the lower horizontal surface of the in Fig. 4 the topmost wooden board B and at the same time already the upper horizontal surface of at least one underlying wooden board B.

[0076] After the processing portal 3 has completed the entire reverse movement, the top wooden board B is separated from the remaining round timber H and can be picked up and transported further by the first transport device 11 of the sorting system 10, which is not shown here.

[0077] Before the in Fig. 5 As the depicted forward movement is carried out, the machining elements are adjusted in the vertical and horizontal directions: The milling heads 5.1 and 5.2 are moved horizontally towards each other, the milling heads 5.3 and 5.4 are moved apart, and the vertically aligned saw 7.2 of the splitting device 7 is moved linearly in the horizontal direction.

[0078] At the in Fig. 5 As the machining portal 3 is moved forward, two wooden boards B of different widths are cut from the uppermost layer of the round timber H. The two milling heads 5.1 and 5.2 produce the outer side surfaces of the wooden boards B, the saw 7.2 produces the two inner side surfaces of the wooden boards B, and the saws 6.1 and 6.2 produce the two lower horizontal surfaces as well as the upper horizontal surface of the next layer.

[0079] After the cut has been made, the two wooden boards B are again picked up by the first transport device 11 and transported for further processing.

[0080] Before processing according to Fig. 6 Starting with a reverse movement of the machining portal 3, the round timber H is rotated 90° – in this case to the right – via the (not shown) holding device 4. This causes the surface, which was planed in the first steps, to lie on its side and be vertically oriented.

[0081] In Fig. 6 The milling heads 5.3 and 5.4 have been moved back towards each other, the milling heads 5.1 and 5.2 are again far apart, and the vertical saw 7.2 of the splitting device 7 has been moved away from the log H. As a result, the now top surface of the log H is being planed by the milling heads 5.3 and 5.4 (and by the horizontal saws 6.1 and 6.2).

[0082] In Fig. 7 After the machining elements have been adjusted accordingly, the (not shown) machining portal 3 moves forward, so that – almost identically to in Fig. 4 - a wooden board B is cut out of the round log H.

[0083] Before the in Fig. 8 In the depicted reverse movement of the processing portal 3, the round timber H is rotated 90° to the right and the processing elements are adjusted accordingly. Fig. 8 The side of the round timber H that is now on top is then milled flat.

[0084] The Fig. 9 is identical to Fig. 8 .

[0085] In Fig. 10 will be - just like in Fig. 7 - the top wooden board B was cut out of the round log H.

[0086] Fig. 11 essentially corresponds to the Fig. 5 , in this case, when moving backwards, the cutting of the two wooden boards B is carried out via the vertical saw 7.1 and the milling heads 5.3 and 5.4.

[0087] Before the forward movement according to Fig. 12 Once the process starts, the log H is moved another 90° to the right via the holding device 4. The top side of the log H is then planed by the milling heads 5.1 and 5.2.

[0088] In Fig. 13 When moving backwards, a wooden board B - the so-called side board - is cut out of the round timber according to the round timber cutting pattern H cut.

[0089] Finally, in Fig. 14 Layer by layer, the individual wooden boards B were cut out of the remaining round timber H. Again, before cutting each layer, the processing elements were adjusted accordingly in the vertical direction and, if necessary, in the horizontal direction.

[0090] Up to the last processing step according to Fig. 14 The round timber H is held by the at least two (not shown here) holding jaws 4.1 and 4.2 of the holding device 4, wherein the holding jaws 4.1 and 4.2, in a holding position, engage essentially centrally on opposite end faces S of the round timber H. Before the position according to Fig. 14 The gripping is changed such that at least two clamping elements 4.3 and 4.4, separate from the holding jaws 4.1 and 4.2, hold the round timber H over lateral surfaces J.

[0091] In the Fig. 15 und 16 An example of a debarking device 20 is shown. Fig. 15 is shown in a top view and in Fig. 16 in a longitudinal section. The log H is loaded, for example, from a truck (timber transporter) onto the infeed area 19. From there, the log H rolls to the debarking device 20. The debarking process itself is not described in detail here, as this is a process known to those skilled in the art. The debarking can be carried out and / or monitored by an operator. The debarked logs H can then be individually scanned by the first scanning device 8.

[0092] In Fig. 17 In a three-dimensional oblique view, most of the components of the woodworking device 1 are visible. The machine frame 2 is aligned along the longitudinal direction L.

[0093] A guide device 14 for feeding the round timber H is arranged on the machine frame 2. The guide device 14 has two horizontal supports 15, which are oriented essentially perpendicular to the longitudinal axis L. Guide pieces 16, preferably V-shaped, are movably mounted on the supports 15. (Preferably, the guide pieces 16 are mounted so as to be linearly movable in the horizontal direction perpendicular to the longitudinal direction L along the supports 15.) Fig. 17 It is evident that a (partially already processed) round timber H rests on these two guide pieces 16 and has already been moved towards the machine frame 2 by the guide pieces 16.

[0094] A holding device 4 for holding the round log H is arranged on the machine frame 2. The holding device 4 has at least two holding jaws 4.1, 4.2, wherein the holding jaws 4.1, 4.2, in a holding position, engage substantially centrally on opposite end faces S of the round log H.

[0095] The two holding jaws 4.1 and 4.2 are each part of a so-called tailstock. A tailstock serves to support long workpieces (in this case, the round timber H) by means of a center point that engages the end face of the workpiece. Thus, a tailstock center point forms a holding jaw 4.1 or 4.2.

[0096] Specifically, a tailstock has a vertical guide rail 4.5 arranged on the machine frame 2, on which a support 4.6 is mounted so as to be movable in the vertical direction. The centering point, together with the holding jaw 4.1 or 4.2, is mounted so as to be movable on the support 4.6. Specifically, this centering point can be moved relative to the support 4.6 in the longitudinal direction L. Thus, the centering points of the two tailstocks, together with their holding jaws 4.1 and 4.2, can move towards and away from each other. This allows the holding device 4 to hold round logs H of different lengths (a greater distance between the holding jaws 4.1 and 4.2 for longer round logs H; a smaller distance for shorter round logs H).

[0097] The holding device 4 (or each tailstock) has corresponding drive means for automatically carrying out the relative movements of the holding jaws 4.1 and 4.2 to the machine frame 2.

[0098] A machining portal 3 is mounted on the machine frame 2 so as to be movable in the longitudinal direction L. In the Fig. 17 In the case shown, the processing portal 3 has two portal parts 3.1 and 3.2 that can be moved together but also separately.

[0099] Travel rails 2.1 are arranged on the machine frame 2. The machining portal 3 can, for example, be mounted on rollers on the travel rails 2.1 so that it can be moved.

[0100] The cutting device 6 for cutting the round timber H is arranged on the portal part 3.1, wherein the cutting device 6 has at least one (in this case horizontally oriented) saw 6.3 in the form of a band saw. The drive motor 6.4 for the band saw is also attached to the portal part 3.1.

[0101] The splitting device 7 for splitting the round timber H is arranged on portal part 3.1. In the Fig. 17 However, in the oblique view shown, its essential components are obscured by portal part 3.1.

[0102] The edging device 5 for edging the round timber H is arranged on the portal part 3.2. In the illustrated case, this edging device 5 has three milling heads 5.1, 5.2 and 5.3 together with associated drive motors 5.5, 5.6 and 5.7.

[0103] Especially if no separate, upstream debarking device is provided, a (relatively small) independent debarking device 20 for debarking the round log H already clamped on the holding device 4 can be movably mounted directly on the machine frame 2.

[0104] In the background are in Fig. 17 also already shown essential components of the sorting system 10, for example the first transport device 11 in the form of a handling robot equipped with a vacuum suction cup.

[0105] In Fig. 18 Figure 1 shows a side view of the woodworking device 1 including the sorting system 10. It is clearly visible that the portal section 3.1 of the machining portal 3 is mounted on the guide rails 2.1 of the machine frame 2.

[0106] The drive motor 6.4 for the saw 6.3 of the cutting device 6 is arranged on the portal part 3.1.

[0107] The splitting device 7 has a vertically oriented saw 7.1, which is driven by the drive motor 7.3.

[0108] The milling heads 5.1, 5.2 and 5.3 of the edging device 5 are also visible. The debarking device 20 is also shown.

[0109] The support 4.6 for a tailstock is arranged on the machine frame 2. Furthermore, the bearing 15 and the guide pieces 16 are connected to the machine frame 2.

[0110] The first transport device 11 is mounted on an independent base 11.1 so as to be rotatable at least about a vertical axis of rotation.

[0111] The sorting system 10 has a second scanning device 9 for scanning the wooden boards B cut from the log H. The scanning device 9 is mounted to move along the longitudinal track 9.1 in the direction L. For this purpose, a cut wooden board B is placed from the first transport device 11 onto the assessment platform 25. The scanning device 9 then moves along the track 9.1 and scans the wooden board B placed on it. Depending on the category of the wooden board B determined by the scan, the wooden board B is sorted into the sorting box 26. For this purpose, corresponding conveyor belts 25.1 and 26.1 are arranged at the assessment platform 25 and in the sorting box 26, respectively. After the category has been determined, the assessment platform 25 first moves vertically to the corresponding category K1, K2, etc. in the sorting box 26. Then the conveyor belts 25.1 and 26.1 begin moving.1 to move and bring the wooden board B horizontally into the corresponding position of the sorting box. As soon as a layer is full of wooden boards B, these wooden boards B can be transported via the layer conveyor belt 27 into the slat magazine 28.

[0112] The components of the sorting system are in Fig. 18 and Fig. 17 They are all drawn in the same way and are sometimes relatively easy to see.

[0113] In Fig. 19 This is a view from a rear oblique angle. Most of the components of the woodworking device 1 are again visible, with the same reference numerals denoting the same parts, units, or components. In this Fig. 19 The second transport device 12 (handling robot) is also shown, which can be moved along the base 12.1 in the longitudinal direction L. With this second transport device 12, the wooden boards B can be assembled into individual stacks of boards P, which can then be transported further by trucks or other means of transport.

[0114] Fig. 20 Figure 1 shows a 3D view of the woodworking device 1 from a different direction. In contrast to the previous illustrations, the portal part 3.2 has moved backwards along the machine frame 2 to edge the log H with the edging device 5.

[0115] Fig. 21 The woodworking device 1 is shown before the start of this edging process. The round log H is moved upwards along the guide rails 4.6 via the support device 4 and its holding jaws 4.1 and 4.2. As a result, the round log H no longer rests in the V-shaped guide pieces 16 and can therefore be rotated by turning the holding jaws 4.1 and 4.2 (for example, by 90°).

[0116] In Fig. 22 The portal part 3.2 now moves along the machine frame 2 and edges the round timber H.

[0117] In Fig. 23 The portal part 3.1 also moves along the machine frame 2, so that a wooden board B is cut from the round timber H by the cutting device 6.

[0118] In Fig. 24 The log H is no longer held between the holding jaws 4.1 and 4.2. Instead, the log H is held by two clamping elements 4.3 and 4.4, separate from the holding jaws 4.1 and 4.2, via cylindrical surfaces J. These clamping elements 4.3 and 4.4 each have clamping jaws that can be moved towards each other to grip and hold a pre-trimmed cylindrical surface J from the rear and front sides. The entire clamping elements 4.3 and 4.4 can, in turn, be moved vertically along the guide rails 4.7.
