    The invention relates to a method for processing a tree trunk, which is profiled after alignment with respect to a longitudinal axis by means of at least one tool to a block of wood and then sawn into lumber.
    In order to ensure a good timber utilization by processing small amounts of waste during the processing of logs, it is known (AT 387745 B) to align the logs on a longitudinal conveyor with respect to their longitudinal axis before processing. This can be done for example by means of both sides of the longitudinal conveyor rotatably mounted and each other in pairs opposite straightening arms. In addition, it is known from the AT 365505 B to profile logs before processing into boards to a wood block, which serves as a starting work for sawing the boards. The aligned tree trunks or the profiled wooden blocks are fed to such a preparation via a longitudinal conveyor of a band saw and processed into boards.
    A disadvantage of these known methods, however, is that complex and fault-prone processing lines must be provided for the logs for passing through the individual processing stations, with the transport of the logs in the longitudinal direction a re-clamping between the individual processing stations is required, which affects the processing accuracy. In addition, due to the successive in the longitudinal direction of the logs processing stations a considerable amount of space is given.
    The invention is therefore based on the object, a method for processing logs in such a way that a good timber utilization in conjunction 2/20 2 can be ensured with accurate processing with relatively simple design means and small footprint.
    Starting from a method of the type described, the invention solves the problem by the fact that the tree trunk is aligned by a displacement of at least one root end transversely to the tree trunk relative to a longitudinal axis and tensioned in its alignment coaxial with the longitudinal axis before the taut tree trunk while maintaining the restraint is profiled into a block of wood with the aid of the movable along the tree trunk tool, after which the block of wood is spanned in the clamping position for the profiling and sawed into sawn timber.
    By aligning the tree trunk to be processed with respect to a longitudinal axis, which represents the essential reference axis for the subsequent processing, the tree trunk can be clamped according to this orientation processing and profiled into a block of wood. Since not the tree trunk compared to the fixed tools, but the tools are moved relative to the clamped tree trunk, the space requirement is determined essentially by the length of the tree trunks to be processed. Only after the profiling of the log to a block of wood as a starting work for the production of sawn wood block is spanned to saw it unhindered can, for example, with the help of circular saws, which in turn are moved along the spanned without change in position wooden block. After the profiling of the tree trunk to a block of wood can be already separated with the help of circular saws a part of the timber from the block of wood, before the wood block is spanned for further sawing.
    Particularly simple construction conditions arise in this context, when the taut tree trunk is shifted axially parallel to the longitudinal axis before profiling because then already a new tree trunk can be aligned and stretched during the sawing of the wood block. The tree trunk thus needs to be shifted only transversely to its longitudinal direction after its orientation for its complete processing.
    Since in general the required for a good wood utilization position of the log relative to a relevant reference for the subsequent processing axis can be determined only after a survey of the log, the tree trunk can be aligned after a survey with respect to the predetermined longitudinal axis and rotated after its clamping in a predetermined reference rotational position become. This reference rotational position depends on the arrangement of the processing tools and ensures a low waste.
    In this context, particularly simple machining conditions arise when the clamped tree trunk or the clamped wood block is rotated by 90 ° between individual related to a longitudinal side of the tree trunk or the wood block processing steps. If two tools lying opposite one another with respect to the tree trunk or the wood block are available, the tree trunk or wood block is first processed on two opposite sides and after only a 90 ° rotation on the two remaining longitudinal sides.
    To achieve constant processing results, the profiling of the tree trunk or the sawing of the profiled wood block can be carried out according to a machining program selected from stored machining programs as a function of a tree trunk measurement. On the basis of the surveying results of the tree trunk, a machining program is selected from a number of stored processing programs, which enables optimum processing for the tree trunk to be processed and the lumbers to be produced. Of course, parameters of the stored machining programs can also be adapted to the results of the tree trunk measurement.
    To carry out the method, it can be assumed that a device comprising a device for aligning the tree trunk with respect to a Längsach- 4/20 4 se, a processing device for profiling the tree trunk to a block of wood and means for sawing the block of wood in lumber. Such a device is then characterized in that the means for aligning the log two arranged with a mutual distance in the trunk longitudinal direction, at least one of which is adjustably mounted in a direction transverse to the longitudinal axis extending stem, and a tree trunk aligned end face clamping device and has the processing device comprises at least one tool that can be moved parallel to the longitudinal axis. By the root support, which is mounted horizontally and vertically adjustable in a plane extending transversely to the longitudinal axis, a spatial orientation of the tree trunk is made possible with respect to the longitudinal axis predetermined by the tensioning device, so that the tree trunk through the tensioning device in a convenient location for timber utilization recorded and offered to the editing tools. Since the tools are displaceable relative to the tree trunk held in the clamping device in a manner suitable for processing, it is not necessary to recompose the tree trunk for profiling the tree trunk to a wood block, whereby the need for longitudinal conveyance of the tree trunk can be minimized by minimizing the space requirement. Particularly advantageous processing conditions arise when the processing tools can be adjusted or moved in the direction of 3 axes.
    If the clamping device is displaced axially parallel to the longitudinal axis between the alignment device and the processing device for the production of a wood block, the throughput can be increased accordingly, because during the processing of the wood block a new tree trunk can already be aligned and stretched.
    Particularly advantageous construction conditions arise when the clamping device has two holding the tree trunk between turning crowns Pinoien, because in this case the tree trunk can be rotated about the 5/5 5 longitudinal axis determined by the turning crowns in a parked on the tools processing position and recorded.
    Thus, the set rotational position is not changed in the transverse displacement of the clamping device, the Pinoien can be moved axially parallel to the longitudinal axis via a guide in the manner of a Gelenkgleichallelogramms. Such a guide in the manner of a Gelenkparallelogramms indeed causes a displacement of the tree trunk parallel to itself, as is the case with a possible linear guide.
    The frontal clamping of the tree trunk to its profiling hinders the sawing of the profiled wood block. For this reason, the wood block is preferably re-clamped without its displacement. For this purpose, the device for sawing a clamping bracket provided with the profiled wood block laterally engageable attacks and between the attacks, the wood block, for example, up and down comprehensive clamping jaws. The wood block comprehensive clamping jaws thus hold the wood block in abutment against the attacks, the wood block from the attacks opposite side starting in sawn timber, especially boards, can be sawn.

    6 shows this clamping fixture in a section along a line VI-VI of FIG. 5.
    The device shown has a device 1 for aligning a tree trunk 2, which is placed on two arranged at a mutual distance in the trunk longitudinal direction, provided with a V-shaped receptacle 3 log rests 4. This device 1 is associated with a measuring device 5, which is movable along a guide 6 in the longitudinal direction of the tree trunk 2 and detects the trunk cross-section. The measured tree trunk 2 can then be conveyed transversely to the trunk longitudinal direction to a clamping device 9 with the aid of displaceable along transverse guides 7 transporter or carriage 8 to clamp the trunk 2 coaxially frontally. Since the clamping device 9 determines a longitudinal axis 10 as a reference axis for the processing of the tree trunk 2, the tree trunk 2 is to be aligned with respect to this longitudinal axis 10 in accordance with the result of the measurement. For this purpose, one of the two root supports 4 is adjustably mounted in a direction perpendicular to the longitudinal axis 10 extending plane. The one axis of the adjustment is formed by the transverse guide 7 for the carriage 8, on which the relevant parent support 4 in the other axis of the height is displaced. In Fig. 2 for this purpose, an actuator 11 is indicated in the form of a wedge drive.
    The tensioning device 9 itself may advantageously have two pines 13 holding the tree trunk 2 between rotary crowns 12, the rotary crowns 12 being drive-connected with rotary drives 14. The pines 12 are mounted perpendicular to the longitudinal axis 10 of the clamping device 9 via a guide 15 in the manner of a Gelenkparallelogramms, so that the Pinoien 13 can be moved parallel to itself. In the illustrated embodiment, this guide is formed in the manner of a Gelenkparallelogramms by guided around deflecting wheels of a guide lever 16 chain, but this is not mandatory. The transverse displacement of the clamping device could for example be ensured by means of linear guides. The Anlenklager 17 of the guide lever 16 are arranged adjustable along guides 18, so that by an opposite shift of the Anlenklager along the guides 18, the Pinoien 13 and thus the between the 7/20. 7
    Turning crowns 12 clamped tree trunk 2 axially parallel to the longitudinal axis 10 between the drawn in Fig. 1, raised clamping position in a processing position according to FIG. 3 can be moved. With the help of the rotary actuators 14 of the log 2 can be rotated before profiling even in a resulting due to his survey rotational position in which an advantageous timber utilization is guaranteed.
    The processing device 19, with the help of the measured tree trunk 2 is profiled to a block of wood 2a as a starting work for sawing to sawn timber, especially to boards, preferably has two mutually opposite with respect to the tree trunk 2 tools 20 in a along a longitudinal guide 21st movable carriage 22 are mounted and can be employed with their drive motors 23 perpendicular to the working plane of the tree trunk 2. With the method of the carriage 22 of the opposite machining tools 20 of the tree trunk 2 is profiled on opposite longitudinal sides in one or more operations. For profiling the remaining longitudinal sides of the tree trunk 2 therefore needs to be rotated only by means of the rotary actuators 14 for the rotary crowns 12 by 90 ° to profile the remaining tree trunk sides to the block of wood 2a.
    The wood block 2a is then sawn into sawn timber by means of a sawing device 24. Since according to the embodiment, the machining tools 20 are formed as circular saw blades, these tools are also suitable for sawing the wood block 2a to lumber, so that a separate sawing 24 is unnecessary. However, it must be re-clamped the wooden block 2a, to allow an unobstructed cutting guide for sawing the wood block 2a. For this purpose, a clamping fixture 25 is provided, which on a along guide columns 26 of the height adjustable support 27 on the one hand stops 28 for lateral contact with the wood block 2a and on the other clamping jaws 29 which comprise the profiled wood block 2a above and below and in contact with the attacks 28 hold. The arrangement of the stops 28 and the clamping jaws 29 can be seen in particular Figs. 5 and 6. In order to apply the stops 28 aligned on the longitudinal side of the wood block 2a to the guide blocks 26 opposite the wooden block 2a, the guide columns 26 can additionally be displaced along transverse guide rails 30. The transverse displacement of the clamping bracket 25 is also required in order to profile the log 2 unhindered by this clamping bracket 25 can. The wood block 2a can be released by the clamping device 9 after the takeover by the clamping bracket 25, so that this clamping device 9 can be returned from the processing position of FIG. 3 in the chucking position of FIG. 1 to take over a new tree trunk. The clamped by the clamping bracket 25 wood block 2a can then be sawed unhindered by the clamping device 9 by the sawing device 24, for example, to boards, as indicated in Fig. 6 by the cut surfaces 31. 9.20
