    Digital signal to facilitate determination of the length of the tree stand passing through the processing unit.
    Such transducers are generally mounted on a shaft which is connected to the feed roller in such a way that they are exposed to the environment and / or the vibrations associated with the use of the forest harvester. However, because code converters may include electronic devices, they may be sensitive to vibrations associated with the environment and / or the use of the harvester. This can make reliable use of the code converter difficult and / or result in damage to the code converter at an early stage.

    The exemplary tree processing unit 200 can, as shown schematically in Figs. 1, be coupled to the chassis 110 by means of a coupling part 120. The coupling part 120 may be one of a number of detachable coupling parts. The coupling part 120 may, according to some embodiments, be a hydraulically (or mechanically) functioning boom. The coupling member 120 may include a first end 130 and a second end 140. According to some embodiments, the chassis 110 may be operatively coupled to the first end 130 and the woodworking unit 200 be operatively coupled to the second end 140. While Fig. 1 only represents a single coupling member 120 Viewers should consider that the chassis 110 and the tree processing unit 200 may be connected to each other by a number of coupling parts and / or by other devices, configured to connect the tree processing unit 200 to the chassis 110.
    An exemplary embodiment of the tree processing unit 200 is schematically illustrated in Fig. 2. The exemplary tree processing unit 200 includes, for example, a link portion 210 and a rotation portion 220. The link portion 210 may operatively connect the tree processing unit 200 to the coupling portion 120, and the rotation portion 220 may facilitate rotation. 230. The exemplary tree processing unit 200 may also include one or more wheels (e.g., feed rollers 240 and 245) configured to receive and grip a portion of a tree and feed the tree portion in the direction of the shaft 230 along the tree processing unit 200. The exemplary feed rollers 240 and 24 may individually include a motor 305 operatively coupled to the feed rollers 240 and 245. In some embodiments, the motor 305 may include a mechanism 300 (e.g., a drive shaft) configured to drive the feed rollers 240 and 245. 10 15 20 25 30 35 535 401 The exemplary tree processing unit 200 shown in Fig. 2 may also include, for example, cutting devices 250 and 260. According to some embodiments, the cutting device 250 may include a pair of branch knives (or bark knives) 252 and 254 configured to remove bark and / or branches from a tree star while being fed through the tree processing unit 200. Similarly the cutting device 260 may include a pair of branch knives (or bark knives) 262 and 264 configured to remove bark and / or branches from a tree trunk while being fed through the tree processing unit 200. The tree processing unit 200 may, according to some embodiments, include a further tree processing device 270. shown in Figs. 2 includes, for example, a cutting device 270 which may be in the form of a saw, a blade, and / or a knife, configured to cut a tree trunk near the ground and / or to a number of parts while the tree trunk passes through the tree processing unit 200.
    An exemplary embodiment of the engine 305 incorporated into the exemplary woodworking unit 200 shown in FIG. 2 is schematically illustrated in FIG. The exemplary motor 305 may be, for example, a feed motor, a hydraulic motor, an electric motor or, for those skilled in the art, any other known, suitable motor. The exemplary motor 305 shown in Fig. 3 includes a base member 310 defining a motor housing 312 configured to accommodate, for example, a machine, a hydraulic motor or an electric motor. The motor housing 312 indicates an opening 315 configured to receive a transducer housing 330.
    For example, the transducer housing 330 may typically be hollow and cylindrical in shape. Alternatively, the transducer housing 330 may assume any suitable geometric shape.
    The exemplary transducer housing 330 indicates an opening 335 at one end, and a measuring mechanism for measuring the length of a tree part processed by the tree processing unit 200 may be provided in the housing 330 via an opening 335.
    For example, a transducer 340 may be disposed within the housing 330 along with an indicator 320 and an insulating member 350. According to some embodiments, the indicator 320 may include, for example, a magnet configured to rotate as the motor rotates to drive one or more feed rollers 240 and 245. The transducer 340 may be operatively coupled to the indicator 320 (eg by the code converter 340 reading the displacement and / or rotation of the indicator 320) and may be configured to monitor the rotation of the indicator 320 and generate signals indicating the speed of the motor 305 and / or the magnitude of the angular displacement. The code converter 340 may be, for example, a contactless code converter, such as, for example, a code converter with the trade name 10 15 20 25 30 35 535 401 HOCKEY PUcK ENcoDERTM, from Jonni Devices, LLC. One such converter is a rotary code converter which does not move the surfaces of an object during measurement so that vibrations and shocks from the measured surfaces are not directly transmitted to the electronics in the code converter. Alternatively, other devices, known to those skilled in the art, may be used to generate signals indicating the speed of the motor 305 and / or the magnitude of the angular displacement.
    According to some embodiments, the housing 330 may receive the insulating member 350.
    The insulating member 350 may include a spring, a damper and / or a shock absorber, or any other similar device known to those skilled in the art.
    For example, the isolation member 350 may be engaged with the transducer 340 and may be configured to reduce the transmission of vibrations to the transducer 340 during use of the tree processing unit 200. The isolation member 350 may, as shown in FIG. 3, indicate two ends - one end connected to (eg adjacent to) the transducer 340 and the other end connected to (eg adjacent to) a disc part 360.
    Fasteners 370 may, as shown in Fig. 3, be used to secure the plate member 360 to the base member 310 so that the insulating member 350, the transducer 340, the housing 330 and the indicator 320 may be secured within the base member 310. The fasteners 370 may be screws, bolts, rivets, nails , needles, and / or any other suitable device, adapted to secure the disc portion 360 to the base portion 310.
    According to the exemplary embodiment shown in Figures 2 and 3, while a tree is moving along the axis 230 of the exemplary tree processing unit 200 (see, e.g., Fig. 2), the code converter 340 may generate one or more signals 440 (see Fig. 4). indicating the length of the tree part fed through the tree processing unit 200. For example, as shown in Fig. 4, a control unit 400 may be provided to at least partially control and / or drive the tree processing unit 200. The control unit 400 may, for example, be configured to receive signals 440 from the code converter 340. The signals 440 may indicate the length of a tree part processed by the tree processing unit 200. According to some embodiments, the control unit 400 may generate signals 410, 420 and 430. The control unit 400 may send the signals 410, 420 and 430 to one or more respective cutting devices 250. 260 and 270 to facilitate the removal of branches on the tree and / or to cut the tree into a number of parts. The tree can be cut into equal parts or different lengths depending on, for example, the signals 410, 420 and 430. It is intended that the control unit 400 can be used manually (eg with the input of an operator in real time) and / or automatically (without input by a real-time operator). According to some embodiments, the control unit 400 may be connected to the tree processing unit 10 535 401 200 (for example, it may be incorporated with the tree processing unit 200). In some embodiments, the control unit 400 may be included in a control system (not shown) connected to the chassis 110 (e.g., incorporated with an operator interface on the chassis 110) and / or a control system located far from the tree processing unit 100.
    Industrial applicability The exemplary processing unit and motor can be used in any application where it is desirable to isolate the transducer or other transducer from vibrations and / or harsh environments that may be experienced during, for example, the use of a woodworking machine. For example, since the code converter 340 may be arranged inside the housing 330, the code converter may be isolated from vibrations and / or harsh environments during use of the tree processing unit 200. The location of the code converter 340 within the housing 330 may help improve accuracy in measuring the length of a tree 200. The location of the code converter 340 inside the housing 330 may also help to increase the reliability of the code converter 340 as the code converter 340 will be protected from exposure to the harsh forest environment using the tree processing unit 200. Furthermore, since a contactless code converter does not come into contact with the surfaces so measured that vibrations and shocks from the measured surfaces are not transmitted directly to the electronics inside the code converter, the use of a contactless code converter can help to improve the accuracy of the measurement of the length of the tree processed by the tree processing unit 200.
    It will be apparent to those skilled in the art that various modifications and variations may be made in the engines and machining units shown. Other embodiments will be apparent to those skilled in the art with respect to the description and execution of the embodiments shown herein. It is intended that the specification and examples be considered as illustrative only, with the true scope of the teachings set forth in the following claims.
