Description

[Technical field]

[0001] The present invention relates to a wood processing machine for processing logs which are aligned along the longitudinal direction of the machine, said machine comprising: A machine frame; a processing gantry supported on the machine frame so as to be movable at least in the longitudinal direction; a holding device arranged on the machine frame for holding the logs on the machine frame; It has. Additionally, the invention relates to a wood processing installation comprising such a wood processing device and to a method for processing logs. [Background technology]

[0002] For example, with regard to wood processing machines one can read from US Pat. No. 5,399,623, US Pat. No. 5,493,367, US Pat. No. 5,493,713, US Pat. No. 5,593,623 and US Pat. No. 5,593,713.

[0003] Wood has been used as a material for the manufacture of goods in various structures and ways since the beginning of history. In the process, wood processing has constantly developed further. Nowadays, trees are felled by large machines and immediately processed into logs. The logs are then delivered by trucks to sawmills, where the desired wooden boards are manufactured from the logs by bark stripping, trimming, cutting and splitting. Within such sawmills, large machines are often used, which perform each of the processing steps.

[0004] Such sawmills have several major drawbacks: This sawmill has a large area requirement, since a large number of pieces of wood have to be stored in intermediate storage after each of the various processing steps. There are high transportation costs because the processed wood needs to be transported between each individual station separately. Personnel costs are high because many different machines and vehicles need to be operated separately. In short, in recent months it has been shown that sawmills have a certain degree of monopoly position and, therefore, the possibility of imposing arbitrarily on the price of sawn boards in the event of shortages in raw materials, which results in incalculable price risks for timber construction companies and final consumers.

[0006] SUMMARY OF THE DISCLOSURE It is therefore an object of the present invention to provide an improved wood processing machine. In particular, the above-mentioned drawbacks should be eliminated. In particular, the wood processing device should enable the production of cut wood boards in a space-saving, efficient, rapid and, as far as possible, independent of a sawmill. [Means for solving the problem]

[0007] This is solved by a wood processing device having the features of claim 1. Accordingly, according to the invention, a wood processing machine comprises a trimming device arranged on the processing gantry for trimming the logs, In this case, it is provided that the trimming device has at least one milling head. In addition, the wood processing device has a cutting device arranged on the processing gantry for cutting the logs, the cutting device having at least one horizontally aligned saw. Finally, the wood processing device has a splitting device arranged on the processing gantry for splitting the logs, the splitting device having at least one saw, in particular vertically aligned. Effect of the Invention

[0008] The wood processing machine therefore has a processing gantry, in which the trimming device, the cutting device and the dividing device are arranged. Thereby, the processed wood is no longer laboriously transported back and forth between individual processing stations, but rather at least three processing steps can be carried out within a single processing gantry.

[0009] In other words, the logs remain consistently mounted in the same machine frame via the holding device throughout the entire time that the trimming, sawing and splitting of all the logs into individual wood boards is performed.

[0010] The present invention provides the possibility of a fully automated and labor-saving production of wood boards directly from logs.

[0011] Advantageous embodiments of the invention are set out in the dependent claims.

[0012] To enable automation, a first scanning device is provided for scanning the logs.

[0013] According to an advantageous embodiment, it is provided that by means of said first scanning device the dimensions of said log can be detected. In particular, the (smallest) diameter of the log is detected by this first scanning device. Likewise, the length of the log can be detected.

[0014] In order to enable a reliable, stable and always uniform processing, it is advantageous if the holding device has at least two holding jaws, It is intended that the holding jaws, in the holding position, grip oppositely lying end faces of the log essentially centrally.

[0015] It is particularly advantageous if the log is supported on the machine frame via the holding device so that it can be rotated, preferably in steps of 90°.

[0016] In particular, the holding device has for this purpose at least one drive motor, by means of which the rotation relative to the machine frame 2 is effected.

[0017] It is not excluded that the processing gantry is stationary and that the machine frame is moved relative to the processing gantry, although it is advantageously intended that the machine frame is constructed stationary, for example in a wood processing hall.

[0018] Advantageously, a moving rail is arranged on said machine frame, It is provided that the processing gantry is supported on these moving rails via rollers.

[0019] It is particularly advantageous if the transfer rail extends straight and parallel to the longitudinal direction of the wood processing device.

[0020] The terms "horizontal", "vertical", "forward" and "rearward" used in this specification relate to the state of the assembled woodworking machine when the logs (and thus the longitudinal direction of the woodworking machine) during processing are oriented horizontally. If the woodworking machine is to be positioned at an angle during processing or if it is to be aligned completely vertically, the relevance of the cited words is changed accordingly to the orientation of the woodworking machine.

[0021] The trimming device should be designed in such a way that simple and quick trimming of the logs is possible. Advantageously, it is provided that at least one of the milling heads is rotatably and - advantageously perpendicular to the longitudinal direction - linearly displaceable supported on the processing gantry.

[0022] Additionally, it is possible for provision to be made for at least one milling head to be mounted on the machining gantry so as to be linearly displaceable in the horizontal direction. However, it is advantageously provided that the holding device is mounted so as to be linearly displaceable in the vertical direction relative to the processing gantry and the trimming device of this processing gantry.

[0023] It is possible for it to be provided that the trimming device comprises a drive motor arranged on the processing gantry for at least one of the milling heads of this trimming device.

[0024] According to an advantageous embodiment it is provided that the trimming device comprises at least three milling heads rotatable about vertical rotation axes. Advantageously, each milling head is assigned its own drive motor.

[0025] According to one embodiment, it is possible for four milling heads to be provided, in particular where two of the four milling heads are arranged in front of the cutting device in the longitudinal direction and two of the four milling heads are arranged behind the cutting device in the longitudinal direction. By means of two milling heads each arranged on one side it is possible - as in a dividing device - to carry out trimming (from both sides of the wooden board) depending on the respective direction of movement.

[0026] The cutting device should be designed such that it is possible to cut logs, and it is provided that the at least one horizontally aligned saw of the cutting device is supported linearly displaceable, preferably vertically, on the processing gantry. Alternatively (or additionally), it can be provided that the holding device is supported so as to be linearly movable, preferably vertically, relative to the processing gantry and the cutting device of the processing gantry, so that different layers can be cut out from the log.

[0027] It is furthermore advantageously provided that the at least one horizontally aligned saw of the cutting device is designed in the form of a circular saw or a band saw.

[0028] If the saw of the cutting device is configured as a band saw, it is advantageously provided that this band saw has two cutting areas (oriented perpendicular to the longitudinal direction) on both opposite longitudinal sides of the saw band of the band saw. Thereby, cutting of the log can take place during the backward movement as well as during the forward movement along the longitudinal direction.

[0029] Optionally, the cutting device has two horizontally aligned circular saws arranged one after the other in the longitudinal direction, It is possible that provision is made for both horizontally aligned circular saws to be arranged side by side - viewed transversely to the longitudinal direction - offset. With these two circular saws it is possible for the log to be cut from both sides simultaneously, with this no very large circular saw needs to be used, rather it is sufficient that the radius of the circular saw is larger than the maximum radius of the log to be processed.

[0030] Furthermore, it is advantageously provided that the cutting device comprises a drive motor arranged on the processing gantry for at least one of the saws of the cutting device.

[0031] The splitting device should be designed in such a way that a simple and quick splitting of the logs is possible. Advantageously, it is provided that at least one vertically aligned saw of the dividing device is rotatably and, advantageously in the horizontal direction, linearly displaceably supported on the processing gantry.

[0032] According to an advantageous embodiment it is provided that at least one vertically aligned saw of the dividing device is formed in the form of a circular saw.

[0033] The size of the circular saw should be selected so that the radius of the circular saw is greater than the maximum thickness of the wooden boards to be produced.

[0034] It is furthermore advantageously provided that the dividing device comprises a drive motor for at least one saw of this dividing device, which is arranged on the processing gantry.

[0035] For efficient processing, according to one embodiment, it is possible for the dividing device to have two saws arranged one behind the other in the longitudinal direction and aligned vertically, with both vertically aligned saws being arranged side by side offset - viewed transversely to the longitudinal direction. Thereby, the log may be further divided into three wooden boards located next to each other.

[0036] It is further provided that, advantageously, one of the two vertically aligned saws of the dividing device is arranged in front of the cutting device in the longitudinal direction and the other of the two vertically aligned saws of the dividing device is arranged in the longitudinal direction behind the cutting device.

[0037] It is thereby possible for the log to already be split prior to cutting by only the splitting device which is located upstream of the cutting device in the direction of movement of the processing gantry. As soon as the processing gantry has moved completely along the log and at least one wooden board has been cut accordingly, it moves in the opposite direction, whereby the other of the two vertically aligned saws is then positioned "in front" of the cutting device in the direction of movement and splits the log.

[0038] After the trimming, cutting and splitting has been carried out, it is likewise important to further transport and sort the so produced wood boards as quickly as possible.

[0039] It is therefore particularly advantageous if a sorting facility is provided for sorting the wooden boards.

[0040] to move the cut wood board away from the remaining log; Advantageously, it is provided that the sorting installation comprises a first, advantageously stationary, transport device for the transport of the wood boards cut from the logs.

[0041] As such, it is possible for the first transport device to have a gripper, preferably in the form of a tong. It is preferably provided that the first transport device is configured as a handling robot, which is preferably equipped with a vacuum suction device.

[0042] In order to ensure a compact and reliable production, a housing, preferably closable, for the machine frame together with the processing gantry is preferably provided.

[0043] Particularly preferably, at least the first transport device is also arranged in the housing.

[0044] Furthermore, it is advantageously provided that the sorting installation comprises a second, preferably mobile, transport device for transporting, sorting and stacking the wood boards. Thereby, the wood boards can be allocated instantly and accurately onto a stack with (almost) identical sized wood boards.

[0045] In order likewise to be able to carry out this sorting automatically, it is advantageously provided that the sorting installation comprises a second scanning device for scanning the wood boards cut from the logs.

[0046] Advantageously, it is provided that by means of the second scanning device the dimensions and / or the wood board quality can be detected.

[0047] According to an advantageous embodiment it is provided that the holding device has at least two clamping elements for holding the log via a mantle surface, separate from the holding jaws.

[0048] This allows the holding device to, after cutting of the by-product, The log (or the area left for the main product) is gripped from the periphery so that the main product can be cut completely without the log to be processed having to be removed from the holding device, and It is possible to hold this log (or the area left for the main product) at the side so that the main product can likewise be cut completely without the log to be processed having to be removed from the holding device.

[0049] For automation it is especially important that an open-loop or closed-loop control unit for open-loop or closed-loop control of the wood processing device is provided.

[0050] This open-loop or closed-loop control unit can be coupled to an operating device or an integrated component of such an operating device, so that the operator can operate and control the wood processing machine via a corresponding control program and an operating menu. Such an operating device can have a display, a keyboard, preferably a touch screen.

[0051] Advantageously, a number of log cutting patterns are stored in a memory of said open-loop or closed-loop control unit, It is intended that each said log cutting pattern corresponds to a defined diameter of the log detected by said first scanning device. This makes it possible to ideally adapt the log cutting pattern to the actual dimensions of the log in question, which should then be designed or selected in such a way that there are as few chips as possible and the quality of the individual wooden boards is as high as possible. It is possible for an entire library of different log cutting patterns to be kept.

[0052] Particularly preferably, the processing gantry and the devices arranged thereon, namely the trimming device, the cutting device, the dividing device and the holding device, It is intended to be movable and operable depending on the log cutting pattern corresponding to the detected diameter.

[0053] Thereby, trimming, cutting and sectioning can be carried out fully automatically and quickly by means of a single processing gantry.

[0054] Patent protection is also claimed for a wood processing installation comprising a wood processing device according to the invention.

[0055] In order to provide an efficient wood processing facility which performs all the functions of a conventional sawmill, the wood processing facility advantageously comprises, in addition to the wood processing device: a supply area for the supply of logs; and / or a debarking device for debarking the logs provided, and / or Cuttings drying equipment, and / or A cuttings compaction device, and / or Cuttings container and / or Warehouse for wooden board collection, It is contemplated that the system may include further stations and devices. Of course, further stations and devices may be provided.

[0056] The problem according to the invention is solved by a method according to claim 33. Such a method for processing logs, which are aligned along the longitudinal direction of a wood processing device, comprises the following steps: - holding the logs via a holding device on the machine frame; - a movement of a processing gantry in the longitudinal direction on the machine frame, It has the steps: During this movement of the processing gantry, the following steps are performed: - trimming the logs by means of a trimming device arranged on the processing gantry; In this case, the trimming device has at least one milling head, which is supported on the processing gantry so as to be rotatable and, preferably, so as to be linearly displaceable transversely to the longitudinal direction. - cutting of said logs by a cutting device arranged on said processing gantry; In this case, the cutting device has at least one horizontally aligned saw, the at least one horizontally aligned saw being rotatably and preferably vertically and linearly displaceable supported on the processing gantry. and, - splitting the logs by a splitting device arranged on the processing gantry; In this case, the dividing device has at least one vertically aligned saw, which is rotatably and preferably horizontally and linearly displaceable supported on the processing gantry 3. The steps are carried out.

[0057] In this method it is advantageously possible that the log is intended to be debarked in a debarking device - before being held via the holding device, which can also be arranged on the machine frame.

[0058] Furthermore, advantageously, the holding device holds the log during the trimming via holding jaws which grip the end faces, and After the complete trimming of the log, the holding device the holding device holds the log on its mantle surface via at least two gripping elements separate from the holding jaws, It is intended that the This allows the major product to be cleaved entirely in one "pass" as well.

[0061] 1 there is shown, in a schematic manner, a woodworking facility 18. Such a woodworking facility 18 can be built on the premises of a carpentry business, i.e. it can be practically anywhere. An advantageous location is, for example, in the immediate vicinity of a production hall for wood-prefabricated components (wooden walls, etc.) - in particular to keep transport routes to a minimum. Such a wood processing facility 18 is located within a distance of approximately 500 m 2 Only a foundation of about 25,000 Festmeters (m2) is required (without shift operation). 3 ) annual production capacity can be achieved. For a production capacity of approximately the same amount, in a conventional sawmill, by contrast, 20,000 m 2 It requires a basic understanding of the following:

[0062] In order to accomplish all the basic functions and production processes as in a sawmill, the wood processing facility 18 comprises, alongside the wood processing device 1 (together with the sorting facility), the following components or stations: - supply area 19 for the supply of logs H, - a debarking device 20 for debarking the supplied logs H, optionally a cuttings drying device 21, optionally a chip compactor 22; optionally a cutting waste container 23 and / or - Warehouse 24 for wooden board stacks P, It is equipped with:

[0063] For the purposes of the present invention, the wood processing device 1 here is the key component or station.

[0064] The arrangement of the individual stations should be expedient per se and adapted to the available space, as long as an efficient working method is possible. In Fig. 2, this wood processing device 1 is illustrated diagrammatically in a side view.

[0065] In the left-hand area, on the other hand, a feed area 19 for the logs H is also shown. This feed area can be designed like a feed area 19 known per se, for example with rollers.

[0066] The wood processing device 1 has a preferably closable housing 13 for the machine frame 2 together with the processing gantry 3 . Before the log H is held in the processing gantry 3, it passes through a first scanning device 8 for scanning the log H. The first scanning device 8 measures the size M of the log H. H can be detected.

[0067] The wood processing device 1 comprises a holding device 4, a trimming device 5, a cutting device 6 and a dividing device 7, which will be explained in more detail later.

[0068] Furthermore, the wood processing device 1 comprises a sorting installation 10 for sorting the wooden boards B cut from the logs H. This sorting installation 10 has a first transport device 11 (for example in the form of a handling robot with a vacuum suction device) for transporting the wooden boards B cut from the logs H.

[0069] It is possible for the wood processing device 1, preferably the sorting facility 10 of this wood processing device, to have a second scanning device 9 for scanning the wooden boards B cut from the logs H. By means of this second scanning device 9, the dimensions M of the wooden boards B are obtained. B , and / or wood board quality is detectable.

[0070] The sorting installation 10 has a second, advantageously mobile, transport device 12 for the transport, sorting and accumulation of the wooden boards B. These wooden boards B can then be stored on a wooden board pile P in a warehouse 24.

[0071] An open-loop or closed-loop control unit 17 for open-loop or closed-loop control of the wood processing device 1 is also provided. In the memory of the open-loop or closed-loop control unit 17 a number of log cutting patterns H cut is stored, and each log cutting pattern H cutis detected by the first scanning device 8, the specified diameter or dimension M of the log H H corresponds to. An open-loop or closed-loop control unit 17 is coupled in signal technology to the scanning device 8. Via the open-loop or closed-loop control unit 17 - depending on the respective configuration - the remaining components of the wood processing device 1 can also be open-loop or closed-loop controlled.

[0072] In Figures 3 to 14 a log H is shown in a three-dimensional view from the front. Some components of the wood processing device 1 have been faded out, so that only the milling heads 5.1, 5.2, 5.3 and 5.4 of the trimming 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 visible. Within the log H, a generally defined log cutting pattern H cut This prescribed log cutting pattern is drawn to determine the dimension M of the log H. H Within this log H, the log is digitally fitted based on the detection carried out earlier. Accordingly, FIGS. 3 to 14 only correspond to a kind of preliminary visualization of the shape in which the individual wooden boards B have to be cut from the log H still remaining in one piece.

[0073] In FIG. 3, the first step of the processing process now takes place. For this purpose, the movably supported devices, namely the trimming device 5, the cutting device 6 and the dividing device 7, are moved (along the machine frame 2, not shown) in the longitudinal direction L on the not shown processing gantry 3. This movement takes place from rear to front, but can of course also take place vice versa, from front to rear. Both milling heads 5.1 and 5.2 mill the upper area of ​​the log H. This results in a plane milling of the debarked tree.

[0074] In Fig. 4 the first step has already been completed and the "upper" layer has been completely milled away, now in a second step the processing gantry 3 moves backwards again together with the devices 5, 6 and 7 arranged on it.

[0075] Prior to the start of this retraction movement, the milling heads 5.1 and 5.2 are moved away from each other or, respectively, moved relative to the machining gantry 3 perpendicularly to the longitudinal direction L, while the milling heads 5.3 and 5.4 perform opposite movements. 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 and - at least in the horizontal direction perpendicular to the longitudinal direction L - linearly displaceably supported on the processing gantry 3.

[0076] Prior to the rearward movement of the processing gantry 3, a further vertical relative movement between the devices 5, 6 and 7 and the log H also takes place. For this purpose, the devices 5, 6 and 7 are - can be moved vertically (downwards) relative to the processing gantry 3; or the entire processing gantry 3 together with the log H can be moved vertically (downwards) relative to the machine frame 2, Or the log H can be moved vertically (upwards) relative to the processing gantry 3.

[0077] The horizontal position adjustment as well as the height adjustment of the individual processing elements (milling head, saw) is performed by an open-loop or closed-loop control unit 17 according to a predefined log cutting pattern H cut An adaptation of the position of the respective processing element is carried out before each new backward or forward movement of the processing gantry 3 along the machine frame 2.

[0078] During the movement of the trimming device 5 backwards, along the log H, the milling heads 5.3 and 5.4, which are here located forward and narrowly side by side according to Fig. 4, trim the (new) uppermost layer of the log H. The milling heads 5.3 and 5.4 thus generate both lateral faces of the uppermost wooden board B in Fig. 4. At the same time, the saws 6.1 and 6.2 cut the log H, so that the uppermost wooden board B is separated from the log H. The saws 6.1 and 6.2 thus generate the lower horizontal surface of the uppermost wooden board B in FIG. 4 and at the same time already the upper horizontal surface of at least one wooden board B located below it.

[0079] After the processing gantry 3 has performed the complete retraction movement, the uppermost wooden board B has been separated from the remaining logs H and can be received and further transported by a first transport device 11 of the sorting installation 10, not shown here.

[0080] Before the forward movement illustrated in FIG. 5 is carried out, the processing element is also vertically and horizontally aligned: The milling heads 5.1 and 5.2 are moved horizontally towards each other, the milling heads 5.3 and 5.4 are moved away from each other and the vertically aligned saw 7.2 of the dividing device 7 is moved horizontally and linearly.

[0081] During the forward movement of the processing gantry 3 illustrated in FIG. 5, two wooden boards B of different widths are cut off from the now uppermost layer of the log H. Both milling heads 5.1 and 5.2 generate the outer sides of these wooden boards B, the saw 7.2 generates both inner sides of these wooden boards B, and the saws 6.1 and 6.2 generate both lower horizontal faces and already the upper horizontal face of the next layer.

[0082] After the cuts have been made, both wooden boards B are again gripped by the first transport device 11 and transported to further processing.

[0083] Before processing according to FIG. 6 begins by the backward movement of the processing gantry 3, the log H is rotated by 90° - in this case to the right - via a holding device 4 (not shown here). Thereby, in the first step the surface which has been plane milled lies sideways and is now oriented vertically.

[0084] In FIG. 6, the milling heads 5.3 and 5.4 have again been moved towards each other, the milling heads 5.1 and 5.2 have again been spaced farther away from each other, and the vertical saw 7.2 of the splitting device 7 has again been moved away from the log H. Thereby, the upper lying area of ​​the log H is now plane milled by the milling heads 5.3 and 5.4 (and by the horizontal saws 6.1 and 6.2).

[0085] In FIG. 7, after a corresponding position adjustment of the processing elements, a forward movement of the processing gantry 3 (not shown) takes place so that - approximately in the same way as in FIG. 4 - a wooden board B is cut from the log H.

[0086] Before the backward movement of the processing gantry 3, which is illustrated in Fig. 8, the log H is on the other hand also rotated by 90° to the right and the processing elements are correspondingly positioned. In Fig. 8, the upper flank of the log H is then now plane milled.

[0087] FIG. 9 is consistent with FIG.

[0088] In FIG. 10 - as in FIG. 7 - the uppermost wooden board B is cut from a log H.

[0089] FIG. 11 essentially corresponds to FIG. 5, where in this case, during the retreating movement, cutting of both wooden boards B takes place via the vertical saw 7.1 and the milling heads 5.3 and 5.4.

[0090] Before the forward movement according to Fig. 12 begins, the log H is again moved by 90° to the right via the holding device 4. On its upper lying side, the log H is plane milled by the milling heads 5.1 and 5.2.

[0091] In FIG. 13, during the retreating movement, the wooden board B - the so-called Seitenware - is cut into logs in the following manner: cut According to the method, it is cut from the log.

[0092] Finally, in FIG. 14, layer by layer, the individual wooden boards B are cut from the remaining log H. On the other hand, it goes without saying that for each layer, prior to cutting, a corresponding adjustment of the processing elements in the vertical and, if applicable, horizontal direction takes place.

[0093] Up to the final processing step according to FIG. 14, the log H is held via at least two holding jaws 4.1 and 4.2 of a holding device 4 (not shown here), whereby: In the holding position, these holding jaws 4.1, 4.2 grip oppositely located end faces S of the log H essentially centrally. Prior to the position according to FIG. 14, a circumferential grip is provided in which at least two clamping elements 4.3 and 4.4, separate from the holding jaws 4.1 and 4.2, hold the log H via its mantle surface J.

[0094] In Figures 15 and 16 an exemplary debarking device 20 is shown. In Figure 15 the debarking device 20 is shown in plan view and in Figure 16 in longitudinal section. The logs H are loaded, for example from a truck (wood transport device), into a feed area 19. From there, the logs H are rolled into a bark removing device 20. The debarking itself is not shown in detail in this figure, since it is a process well known to those skilled in the art. The debarking can be performed and / or monitored by an operator. The debarked logs H can then be individually scanned by a first scanning device 8.

[0095] 17 a three-dimensional perspective view of most of the structural members of the wood processing machine 1 can be seen. The machine frame 2 is oriented along a longitudinal direction L.

[0096] In the machine frame 2, a guide device 14 for the supply of logs H is arranged. The guide device 14 has two rests 15 which are horizontal and oriented essentially perpendicular to the longitudinal direction L. In these rests 15, preferably V-shaped guide pieces 16 are supported so as to be movable (preferably in a horizontal direction, perpendicular to the longitudinal direction L, linearly along the rests 15). It can be seen in FIG. 17 that a (partially already processed) log H is placed on both of these guide pieces 16 and has already been moved by these guide pieces 16 into the machine frame 2 .

[0097] A holding device 4 for holding the log H flat is arranged on the machine frame 2. The holding device 4 has at least two holding jaws 4.1 and 4.2, In the holding position, these holding jaws 4.1 and 4.2 grip the oppositely located end faces of the log essentially centrally.

[0098] The two holding jaws 4.1 and 4.2 are each part of a so-called tailstock, which serves to support a length of workpiece (in this case a log H) by means of an aligning tip which engages into this workpiece on the end side. The tailstock-aligning point thereby forms a holding jaw 4.1 or 4.2.

[0099] In particular, the tailstock has a vertically oriented moving rail 4.5 arranged on the machine frame 2, on which a carrier 4.6 is mounted so as to be movable in the height direction, and on which the centering tip together with the holding jaws 4.1 and 4.2 is also movably mounted. In particular, this aligning tip can be moved in the longitudinal direction L relative to the carrier 4.6. Thus, the aligning tips of both tailstocks together with the holding jaws 4.1 and 4.2 of these tailstocks can be moved towards each other and away from each other. This enables the holding device 4 to hold logs H of different lengths (with a larger distance between the holding jaws 4.1 and 4.2 in the case of a long log H; and with a smaller distance in the case of a shorter log H).

[0100] The holding device 4 (or the respective tailstock) has corresponding drive means for automatic implementation of the relative movement of the holding jaws 4.1 and 4.2 with respect to the machine frame 2.

[0101] In the machine frame 2, the processing gantry 3 is supported so as to be movable in the longitudinal direction L. In the case shown in FIG. 17, the processing gantry 3 has two gantry parts 3.1 and 3.2 which are movable in common with respect to one another, but which are also movable separately from one another.

[0102] In the machine frame 2, transfer rails 2.1 are formed. It is possible for a processing gantry 3 to be movably mounted on these transfer rails 2.1, for example via rollers.

[0103] In the gantry element 3.1, a cutting device 6 for cutting the logs H is arranged, this cutting device 6 having at least one saw 6.3 in the form of a band saw (in this case aligned horizontally), a drive motor 6.4 for this band saw is also mounted in this gantry element 3.1.

[0104] In the gantry element 3.1 a splitting device 7 for splitting the logs H is arranged. In the perspective view shown in FIG. 17 the essential components of this splitting device are however obscured by the gantry element.

[0105] On the gantry element 3.2 a trimming device 5 for trimming the logs H is arranged, which in the illustrated case has three milling heads 5.1, 5.2 and 5.3 with the associated drive motors 5.5, 5.6 and 5.7.

[0106] In particular, if no separate, upstream debarking device is provided, it is also possible for a (relatively small) individual debarking device 20 to be movably supported directly on the machine frame 2 for debarking the logs H already clamped in the holding device 4.

[0107] In this context, in FIG. 17, an already important component of the sorting installation 10, for example a first transport device 11 in the form of a handling robot equipped with a vacuum suction device, is also shown.

[0108] 18, a side view of the wood processing device 1 is shown together with the sorting installation 10. It can be clearly seen that the gantry parts 3.1 of the processing gantry 3 are supported in the moving rails 2.1 of the machine frame 2.

[0109] In the gantry member 3.1 a drive motor 6.4 for the saw 6.3 of the cutting device 6 is arranged.

[0110] The splitting device 7 comprises a vertically aligned saw 7.1, which is driven by a drive motor 7.3.

[0111] Also visible are the milling heads 5.1, 5.2 and 5.3 of the trimming device 5. The bark removing device 20 is likewise illustrated.

[0112] A support 4.6 for a tailstock is arranged on the machine frame 2. Furthermore, a rest 15 and a guide piece 16 are connected to the machine frame 2.

[0113] The first transport device 11 is rotatably mounted on a specific base 11.1 at least about a vertical axis of rotation.

[0114] The sorting installation 10 has a second scanning device 9 for scanning the wood boards B cut from the logs H. This scanning device 9 is supported so as to be movable in the longitudinal direction L along a moving rail 9.1. For this purpose, the cut wood boards B are laid on an evaluation platform 25 by the first transport device 11. The scanning device 9 then moves along a moving rail 9.1 and scans the wooden board B placed on the evaluation platform. Depending on the respective detected category of the wooden board B, the wooden board B is sorted into a sorting box 26. For this purpose, corresponding conveyor belts 25.1 or 26.1 are arranged on the evaluation platform 25 and also in the sorting box 26. After the category has been detected, first of all the evaluation platform 25 moves in the height direction to the corresponding category K1, K2, etc. of the sorting box 26. Then the conveyor belts 25.1 and 26.1 start to move and move the wooden board B horizontally to the corresponding lage of the sorting box 26. As soon as a layer is filled with wooden boards B, these can be transported via a layer conveyor belt 27 into a slat magazine 28 .

[0115] The components of the sorting installation 10 are shown similarly in FIG. 18 and in FIG. 17 and, in parts, are relatively well visible.

[0116] 19, which is a rear perspective view, again most of the components of the wood processing device 1 are visible, with the same reference numbers indicating the same parts, units or components. In this figure 19, a second transport device 12 (handling robot) is also shown, which is movable in the longitudinal direction L along the base 12.1. By means of this second transport device 12, the wooden boards B can be aligned into individual wooden board stacks P which can then in turn be further transported by truck or other transport means.

[0117] 20 shows another three-dimensional view of the wood processing machine 1 from another direction. In contrast to the previous illustration, the gantry member 3.2 has been moved backwards along the machine frame 2 in order to trim the log H by the trimming device 5.

[0118] FIG. 21 shows the wood processing apparatus 1 before the start of this trimming process. Via the holding device 4 and its holding jaws 4.1 and 4.2, the log H is moved upwards along a moving rail 4.5 via a carrier 4.6. Thereby, the log H no longer rests in the V-shaped guide piece 16 and can accordingly be rotated (for example by 90°) by rotation of the holding jaws 4.1 and 4.2.

[0119] In FIG. 22, the gantry member 3.2 now moves along the machine frame 2 and trims the log H.

[0120] 23, the gantry member 3.1 also moves along the machine frame 2 so that a wooden board B is cut from the log H by means of the cutting device 6. In FIG.

[0121] In Fig. 24, the log H is no longer held between the holding jaws 4.1 and 4.2. Rather, the log H is now held via the mantle surface J by two clamping elements 4.3 and 4.4, separate from the holding jaws 4.1 and 4.2. In order to grip the already trimmed jacket surface J from the rear and front sides and thus hold it, these clamping elements 4.3 and 4.4 each have clamping jaws which are movable towards each other. On the other hand, all clamping elements 4.3 and 4.4 can be moved vertically along a moving rail 4.7.

[0122] Finally, FIG. 25 further shows a plan view of the entire wood processing apparatus 1 together with the sorting installation 10.
