    DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION The marking device of the present invention can be used in a harvester assembly to apply an identification mark to the end face of a cut end of one of the gripper means of the harvester assembly. In the following, the marking device will be described with reference to this application. However, this application should only be considered as a non-limiting example and the marking device according to the invention can of course also be used in many other applications for applying a marking to a desired object, for example in a sawmill for applying a marking to logs or boards. .
    Fig. 1 schematically illustrates a harvester assembly 1 for deforestation according to an embodiment of the present invention.
    This harvester assembly 1 is in a conventional manner intended to be carried by a crane mounted on a forest vehicle. The forest vehicle can, for example, be a harvester. In the illustrated example, the harvester assembly 1 is a so-called one-handle harvester assembly, i.e. a harvester assembly which is designed to grip a standing tree by means of gripping means 2, cut the tree by means of a cutting means 3, fold over the tree trunk 4 to a substantially horizontal position (see Fig. 2), and then by means of feed means 5 drive the tree trunk through the harvester assembly while simultaneously pruning the tree trunk by means of pruning means 6. In the illustrated example the pruning means 6 consist of pruning knives arranged on the gripping means 2. 1 the illustrated example 10 comprises the feeder means 5 of the harvester assembly two rotatably driven feed wheels 5a, 5b which are arranged to engage the tree trunk on opposite sides thereof. With the aid of the cutting body 3, the tree trunk 4 can be cut into individual logs. However, the invention is also applicable for so-called whole-trunk handling, ie where the unit is used to cut and fell the tree, but then no cutting of the tree trunk into smaller logs is carried out.
    Fig. 1 shows the harvester assembly 1 with a cut tree trunk 4 (indicated by dashed lines) held by the gripping means 2 with the tree trunk extending in the vertical direction. Fig. 2 shows the harvester head 1 and a tree trunk 4 held therein after the harvester head has folded over the tree trunk to a horizontal position. The operation from vertical to horizontal position takes place by means of a power member 9 in the form of a hydraulic cylinder, which is arranged to turn the part 1a of the harvester assembly in which the stem 4 is held relative to the other part 1b of the harvester assembly which is attached at the crane of the forest vehicle. The harvester unit 1 is of conventional design with respect to the parts described so far.
    The harvester assembly 1 comprises a marking device 10 for applying an identification mark, for example in the form of a suitable code, to the end surface 4a of a cut end of a tree trunk 4 held by the gripping members 2. A log to be formed from a tree trunk 4 to be processed by means of the harvester assembly 1 can thus be provided with an identification mark by means of this marking device 10. the identification mark is applied to the front end surface of the log before the log is cut off from the tree trunk 4 and allowed to fall to the ground from the harvester assembly 1. the identification mark is suitably linked to established and stored information on the place of planting of the tree from which the log is obtained, for example in a manner described in WO 99/23873 A1, in order to make it possible to determine the origin of a marked stock by means of the marking. In connection with the felling, information regarding the log's place of origin, quality, size, seller, buyer, etc. can be stored linked to the identification mark, whereby such information can be retrieved in connection with a later identification of the stock. The identification marking can also be used to monitor the log's movement from the felling to the end customer.
    The position of the marking device 10 in relation to the cutting member 3 of the harvester assembly is schematically illustrated in Fig. 1 with a block made with dashed lines. As can be seen from Fig. 1, the marking device 10 is placed above the cutting member 3 in close proximity thereto. The location of the marking device 10 in relation to the cutting member 3 of the harvester assembly is also illustrated in Figs. 7a and 7b.
    The marking device 10 comprises a percussion arm 11 which is provided with a percussion head 12 at its outer free end. The marking device 10 further comprises operating means 20 for operating the percussion arm 11 and a link device 30, via which the operating means 20 are arranged to act on the percussion arm 11.
    Via the link device 30, the percussion arm 11 is movably connected to a foundation 7 included in the harvester assembly, which is arranged in the vicinity of the cutting member 3 just above this.
    The striking arm 11 is pivotally connected at its inner end to a first link 31 of the link device 30 via a first link L1 which defines a first axis of rotation V1. The first link 31 is pivotally connected to the foundation 7 via a second link L2 defining a second axis of rotation V2 and it is pivotable about this second axis of rotation V2 under the action of the actuators 20. The second axis of rotation V2 is arranged at a distance from and extends parallel to the first axis of rotation V1. The impact arm 11 is pivotable about the first axis of rotation V1 under the action of the operating means 20 and the link device 30 from a rest position (see Figs. 3a, 4a, 5a, 6a and 7a) to an impact position (see Figs. 3c, 4c, 5c, 6c and 7b ), via an intermediate position (see Figs. 3b, 4b, 5b and 6b), to thereby allow the percussion head 12 to strike against the end surface 4a of a cut end of a tree trunk 4 held by the gripping means 2 to apply a marking on said end face. The first link 31 is arranged to pivot about the second axis of rotation V2 under the action of the actuating means 20 during such a movement of the percussion arm 11 from the rest position to the stroke position, whereby said first link L1 and thereby the first axis of rotation V1 is displaced outwardly from the foundation 7. so that the distance between the first axis of rotation V1 and the foundation 7 increases when the percussion arm 11 is moved under the action of the operating means 20 and the link device 30 from the rest position to the stroke position. Said rotary shafts V1, V2 extend perpendicular to the longitudinal direction of a tree trunk 4 held by the gripping means 2.
    In the illustrated embodiment, the first link 31 is at one end articulated connected to the percussion arm 11 via said first link L1 and at its other end articulated connected to a holder 32 rigidly connected to the foundation 7 via said second link L2. The actuating means 20 are arranged to act on a lever link 33 included in the widower device 30 which is hingedly connected to the foundation 7 via a third joint L3 and which is pivotable about a third axis of rotation V3 defined by the third joint L3 under the action of the actuating means 20. The third axis of rotation V3 is arranged at a distance from and extends parallel to the first axis of rotation V1 and the second axis of rotation V2. The lever link 33 is connected to the strike arm 11 via a first connection link 34, which at its one end is articulated to the lever link 33 via a fourth link L4 and at its other end is articulated to the strike arm 11 via a fifth link L5 which is located between the two ends of the percussion arm, i.e. between the percussion head 12 and said first link L1. The lever link 33 is further connected to the first link 31 via a second connection link 35, which at its one end is articulated to the lever link 33 via a sixth link L6 located between said third link L3 and said fourth link L4, and which at its second end is articulated connected to the first link 31 via a seventh link L7 located between said first link L1 and said second link L2. In the illustrated embodiment, the actuators 20 comprise two hydraulic cylinders 20a, 20b (see Figs. 5b and 6b) which are arranged parallel to each other on either side of the striking arm 11. Respective hydraulic cylinders 20a, 20b have a cylinder part 21 which is articulated connected to the foundation 7 and a piston rod 22 which is articulated connected to the lever link 33 via an eighth link L8. The hydraulic cylinders could alternatively be arranged in the opposite direction, i.e. with the piston rod 22 connected to the foundation 7 and the cylinder part 21 connected to the lever link 33. The operating means 20 are omitted in Figs. 3a-3c, 4a, 4c, 5a, 5c, 6a , 6c, 7a and 7b.
    The striking arm 11 advantageously comprises two or more mutually parallel legs 11a, 11b, as illustrated in Figs. 5a-5c and Figs. 6a-6c. Correspondingly, the link 31, 33, 34, 35 of the link device 30 advantageously comprises two or more mutually parallel legs, as illustrated in Figs. 5a-5c and Figs. 6a-6c.
    The legs of the percussion arm 11 and the links 31, 33, 34, 35 are suitably in the form of elongate metal plates arranged side by side with the main surfaces of the plates facing each other, as illustrated in Figs. 5a-5c, 6a-6c, 7a and 7b. As a result, the percussion arm 11 and the link device 30 have a stable construction. In the rest position, the percussion arm 11 and the percussion head 12 are out of the way of a tree trunk 4 held by the gripping means 2 and the tree trunk can then be moved forward along the harvester assembly 1 by means of the feed means 5 without being obstructed by the percussion arm 11 or the percussion head 12.
    The percussion head 12 is provided with marking means to provide the desired identification marking on a log.
    The labeling agents may be of any suitable type. The marking means suitably comprise several individually adjustable marking means 18, each of which is selectively rotatable between different setting positions or selectively adjustable between an active marking position, in which the marking means 18 is arranged to apply a mark on the end surface 4a of a tree trunk struck by the impact head 12, and an inactive position, in which the marking means 10 is prevented from applying a mark to the end surface 4a of a tree trunk struck by the impact head. The mark in question could, for example, be a depression or a color or ink dot.
    The marking device 10 is suitably provided with automatically controlled adjusting means which are designed to set the positions of said adjustable marking means 18, preferably under the control of an electronic control unit, in order thereby thereby making it possible to automatically vary the identification marking provided by the marking means. The percussion head 12 could also be provided with means for attaching an information carrier to the end surface 4a of a tree trunk. Such an information carrier could be provided with the identification mark and / or any other desired information and could for instance consist of an RFID tag (RFID = radio frequency identification), for example in the form of a transponder, an electronic chip, a label, etc. The RFID tags may, for example, be provided on a roll which is operated by means of suitable feeding means provided in the marking device.
    The percussion head 12 is preferably provided with one or more marking means 18 for applying a marking by stamping or punching on the end surface 4a of a tree trunk 4 when the percussion head 12 strikes against said end surface. In this case, in their active marking position, the respective marking means 18 are arranged to penetrate into the end surface 4a of a tree trunk which is struck by the percussion head 12 to provide a depression in the end surface 4a, and in its inactive position prevented from penetrating into the end surface. in a tree trunk hit by the percussion head. Respective marking means 18 may be movable back and forth between an advanced position corresponding to the above-mentioned active marking position and a retracted position corresponding to the above-mentioned inactive position. Respective marking means 18 may have a rounded outer end to facilitate the retraction of the marking means from the end surface 4a of a tree trunk struck by the percussion head 12.
    The percussion head 12 may also be provided with a marking means in the form of a valve which is designed to dispense color or ink when the percussion head 12 strikes the end surface 4a of a tree trunk to thereby apply a color or ink dot. on the end surface of the tree trunk.
    In the illustrated embodiment, the cutting member 3 consists of a pivotally arranged saw blade which has a saw chain extending around its periphery. The saw blade 3 is arranged in a conventional manner in a so-called saw box 8, which is intended to protect the saw blade and its drive equipment from shocks. The saw blade 3 is pivotable in a conventional manner from a rest position inside the saw box 8 (see Fig. 7b) to a deflected position (see Fig. 7a), in which the saw blade 3 protrudes outside the saw box. The marking device 10 is designed so that the striking arm 11 can be moved from its rest position to its striking position and then back to the rest position for the short period of time when the saw blade 3 is in its rest position inside the saw box 8. This allows the striking arm 11 to perform its striking movement before sawing. - the sword 3 is returned to the flung position.
    When the piston rods 22 of the hydraulic cylinders 20a, 20b of the operating means are retracted, the percussion arm 11 is swung back and is in the rest position illustrated in Figs. 3a, 4a, 5a and 6a. In this retracted rest position, the marking device 10 is out of the way of a tree trunk 4 held by the gripping means 2 and the tree trunk can then be moved forward along the harvester assembly 1 by means of the feeding means 5 without being obstructed by the marking device. In this rest position, the marking device 10 is also located above the plane in which the saw blade 3 performs its pivoting movement and is thus out of the way of the saw blade. When the piston rods 22 are pushed forward, they exert a force on the percussion arm 11 and the first link 31 via the lever link 33 and the connecting links 34, 35, which will thereby pivot forward about the first axis of rotation V1 and the second axis of rotation V2 from the position shown in FIG. 3a, 4a, 5a, 6a and 7a show the rest position to the intermediate position shown in Figs. 3b, 4b, 5b and 6b. By this pivoting movement of the first link 31 about the second axis of rotation V2, the first axis of rotation V1 is displaced outwards and forwards so that the distance between the first axis of rotation V1 and the foundation increases. Upon further advancement of the piston rods 22, they will exert a force on the percussion arm 11 via the lever link 33 and the first connecting link 34 which causes the percussion arm to pivot forward further about the first pivot axis V1 from that in Figs. 3b, 4b , 5b and 6b show the intermediate position to the stroke position shown in Figs. 3c, 4c, 5c, 6c and 7b. The percussion head 12 is thereby struck against the end surface 4a of the tree trunk 4 so that a marking is applied to said end surface. Thereafter, the piston rods 22 are retracted so that the percussion arm 11 and the link device 30 are returned from the stroke position illustrated in Figs. 3c, 4c, 5c, 6c and 7b to the rest position illustrated in Figs. 3a, 4a, 5a, 6a and 7a.
    The invention is of course not in any way limited to the embodiments described above, but many possibilities for modifications thereof should be obvious to a person skilled in the art without departing from the basic idea of the invention as defined in the appended claims.
