    专利说明:

    The invention relates to a novel device for cutting elongated wood, in particular of logs, branches, log or logs, in pieces of wood each defined length.
    There are already automatic firewood saws, the basic task, iängiiche wood to pieces of wood each having the desired final length, e.g. for filling furnaces, to fulfill.
    Cutting devices for wood have become known in various embodiments. For example, devices are known in which tree trunks are moved longitudinally toward rotating circular saw blades and are cut longitudinally into boards.
    Furthermore, machines have become known in which tree trunks are moved transversely to the later cutting plane, where they are blended by a movable saw unit, in particular a circular saw, by oscillating movements of the saw blade. This embodiment has the disadvantage that the movable saw blade is technically relatively complex to realize due to the moment of inertia of the rotating saw blade.
    A manual variant, in which pieces of wood are inserted by hand into a tilting circular saw or on the table of a roller table saw and the cutting process is triggered by the operator, has also become known. After the cutting process, the wood is advanced and cut to the desired length. For this purpose, however, two operators are needed. One puts in the wood and the second person cuts down the logs, pushes them on and loads the cut wood pieces.
    EP 1 529 611 B1 describes an automatic cutting device for wood, comprising a sawing unit which is fixedly attached to the same and a feeding device for the wood, which promotes the same perpendicular to the cutting plane of the sawing unit in the direction of the cutting plane, where the transport device of the Saw unit is spatially spaced and the displacement is parallel to the cutting plane in the cutting region of the saw unit in and out of the same back movable, and wherein there are the transport device, the feed zone and the cutting area in a common, horizontal plane.
    DE 29607199 U1 describes a device for sawing preassembled log or round wood with a circular saw, in which the wood is supplied to the saw blade by means of a drum and wherein the saw drum is inclined at 30 to 70 ° inclination, so that the wood by gravity and by the rotational movement of the drum slips down, where there is an adjustable bottom plate as a longitudinal stop.
    All these saws or cutting devices for wood have the disadvantage that in them the device dictates the power stroke and thus the respective operator repeatedly or constantly put in a stressful situation. Furthermore, the operator must constantly check whether the loading tray is already free or if there is still a leftover piece of wood for processing.
    In addition, the task is made more difficult by determining the optimum task time by the operator and it is possible that due to the random task time the piece of wood to be cut has not been advanced to the longitudinal stop of the sawing device and thus wrong section lengths are produced.
    Object of the present invention is to avoid the disadvantages of previously known automatic wood cutting devices and to create a structurally simple and especially easy and safe to use cutting device of the type mentioned.
    The invention is now a new device for cutting elongated wood, in particular log or round wood, in pieces of wood each defined length, soft a stationary and days fixed to the device sawing unit and a Holzzuführeinheit parallel to the cutting plane of the saw unit oscillating in the Cutting area in and out of the same movable wooden holding and sliding loading, and preferably a Abtransporteinrichtung for cut wood pieces, in particular a conveyor comprises, which is characterized - that they by means of a drive unit, preferably hydraulic cylinder, oscillating substantially horizontally transversely movable unit of wood feeder connected to it, preferably with the same unified, wooden holding and sliding load - for exclusively secured by the action of gravity advancing the woods up to a longitudinal stop thereof, which - in the longitudinal direction of the introduced elongated woods obliquely, preferably at an angle α of 25 to 50 °, in particular from 30 to 40 ° to the horizontal and the cutting plane of the saw unit thus substantially perpendicular thereto and the wood feed longitudinal direction is arranged, and - that for a respective adjustment of the Ablängmaßes the pieces of wood, preferably discontinuous, adjustable longitudinal stop fix with a - for determining whether (yet) to be cut wood in the wood holding and slide or not suitable - is coupled sensor, - in turn connected to a control device at least for the drive unit of the wood holding and -Verschiebelade - by means of which (still) presence of wood in said loading and its concerns at the longitudinal stop, the same first perpendicular to the cutting plane of the saw unit and for the section substantially horizontal towards the saw blade of the Saw unit is movable in the opposite direction back and forth to the initial position for a gravitational rearward movement of the elongated wood to the longitudinal stop for a renewed cutting operation, and this horizontally oscillating until the absence of Hoiz in said loading the same can be moved back into its starting position by the sensor, and the saw unit can optionally be switched off.
    The new wood cutting device allows the Ablängvorgang by means of the moving, in particular rotating, saw blade of the relative to said device, however, not movable sawing unit and the horizontally oscillating, obliquely arranged in the longitudinal displacement load. The advance of the wood after each cut is done - after loosening the wood holding element -automatically by gravity along the oblique path of the sliding load in the pointed angle! to the horizontal. After each cut, the cut piece of wood slips down onto the log removal conveyor and is carried away by it.
    The wooden holding element of the sliding load, which is, for example, a spring loaded in the transverse direction by means of the elongated hoiz, holds the wood to be cut in front of the saw blade which ultimately cuts it and during the cutting process itself until the drawer is completely returned to its original position in front of the saw blade stands and then leaves the elongated wood again free until it has slipped by gravity into the voltage applied to the longitudinal stop cutting position.
    The function of the substantially horizontally oscillating displacement load is preferably ensured by means of hydraulic cylinder drive.
    The disadvantages of the hitherto known »automatic firewood saws are inventively eliminated in particular by the innovative equipped with the sensor and along with him mitverstellbaren wood longitudinal stop.
    The new " smart " Longitudinal stop with sensor for the wood fulfills in particular the following tasks:
    The sawing process can only be started and executed at or with the correct cutting length determined by the respective setting of the longitudinal flange.
    If there is no more wood in the sliding drawer », the wooden drawer is brought to the logging or feeding position, stops there and thus shows the operator the possibility of re-feeding wood to be cut down. In this way, in the wood cutting device according to the invention with sensor any control of the wood task for the operator completely eliminated.
    Here, the main advantage is given that the new wood cutting device itself dictates the best possible stroke for the elongation of the elongated pieces of wood.
    The new " smart " Stop with the fixed with him permanently adjustable wood detection sensor according to the invention favorably designed so that the sensor a piece of wood as lying directly in front of the longitudinal stop and touches touching him or there adjoining and only then triggers the then automatic sawing. If the mechanical length stop is adjusted to adjust the length of the cut pieces of wood, the wood detection sensor will be automatically adjusted so that the sensor will always function regardless of the wood length setting.
    As for the sawing unit of the new wood cutting device itself, it may be formed with a circular or bandsaw, a jigsaw, "an endless wire or chain saw, preferably with a circular saw blade".
    The wood detection function can optimally be done by optical sensors, ie by those with laser or IR-Ueht, by capacitive sensors or ultrasonic sensors. A solution by mechanical contact when touching the wood at the longitudinal stop is also possible.
    In particular, to prevent uncontrolled lifting of the supplied wood at the beginning and during the sawing process itself, it is advantageous if the sawing or sawing action of the saw unit, in particular of the saw blade, from top to bottom, ie downward.
    With regard to a flexible use of the new wood cutting device, it is further favorable if it can be coupled by means of three-point to a tractor or is designed as a movable trailer, and the drive of the saw unit, for example by means of the working or articulated shaft of a towing vehicle, in particular tractor , is provided. It is of course also any other drive option, especially on electric or combustion engines (diesel, gasoline) possible.
    Thus, it provides the new wood cutting device in addition to optimal performance due to the cutting device self-timed automatic cutting process at the same time the best possible, uniform firewood quality and at the same time allows the operator a simple operation, with display of the possibility or necessity of a Langholzaufgabe in any case clearly indicated at least by a stoppage of the sliding becomes.
    Reference to the drawing, the invention is explained in detail;
    1 to 4, the new wood cutting device in side view, top view, in a view from the wood task side and in an oblique view, and Figs. 5 and 6 is a view and a detailed view of the new device along that shown in FIG Section plane AA.
    Fig. 1 shows the new wood cutting device 1 and it can be clearly seen in the figure, as the - here forming a unit - Holzaufgabe- and -einlaufeinrichtung 4 and wood holding and sliding shutter 5 in wood addition and longitudinal direction R2 is arranged at an angle a of, for example, 35 ° oblique to the horizontal H, so that the abandoned there, to be cut, elongated logs, branches or logs 2 automatically slide along the underside of the sliding 5 down until it stops at a not visible here longitudinal stop abut the same, the here discontinuous adjustability to each desired lengths I of the sawed Hoizstücke 2 'using Einsteilschlitzen 52 through soft during the cutting process, for example, the fixed mechanical longitudinal stop 5, eg in the form of a stop plate, can penetrate, is clearly visible. The sliding shutter 5 is in the horizontal angle H at an acute angle «oblique plane defined by A-A backwards, aiso away from the viewer, and then back to the front, so towards the viewer, oscillatingly movable.
    In the course of the movement of the sliding shutter 5 to the rear gets the abandoned, elongated wood 2 in the cutting plane 30 of the circular saw blade of the saw unit 3 and there is a piece of wood 2 'cut to length, which falls on the conveyor belt 6 and from the same - here obliquely upward - Is transported away and ultimately dropped by forming a heap of wood from the same.
    From Fig. 2 is - with full retention of reference numerals - clear how the horizontal-oscillating movement of the sliding 5 in the direction of r1 and in the opposite direction r2 takes place together with her here einstückigen Holzaufgabe- 3, which characterized by this oscillatory movement, short Arrows is indicated.
    In FIG. 3, the reference numerals have the same meanings as in FIGS. 1 and 2.
    The overall structure of the new wood sheath device 1 shows - with otherwise constant reference numerals - the Fig, 4 clearly.
    The two Fig. 5 and 6 show - with otherwise constant reference numerals - the next to the longitudinal oblique position of the sliding load 5 for the automatic feed of the Hoizes 2 to the saw unit 3 with rotating blade 31 quite essential feature of the present invention, namely with the longitudinal stop 51 for the Wood 2 fixed coupled and therefore always automatically with him-adjustable sensor 7, which is able to recognize immediately, if the wood supplied due to the inclination of the sliding load 5 alone by the force of gravity and without any further control safely to the longitudinal stop 51 "; & quot slips; and pending there.
    At this moment, it is ensured by means of the control device 9 connected to the sensor 7 that the drive hydraulics 55 moves the sliding load 5 and with it the wood 2 towards the saw blade 31 of the saw unit 3 in the direction Π whose widia teeth
    Wood 2 begin to cut and this movement r1 continues until the so sawn and exactly cut wood piece 2 'falls downwards, so concretely on the conveyor belt 8 of the wood piece removal device and is transported away.
    After the cut, the tray 5 is automatically moved back to the starting position Au.
    The moment this is done, loosens the - not shown -Holzhalterungselement the tray 5 and the sliced timber 2 slips up to the longitudinal stop 51, the sensor 7 detects presence of wood 2 in the sliding load 5 and causes the loading movement hydraulics 55, to move the tray 5 with the held by the support member long wood 2 again in the direction of r1 and so on.
    If no wood 2 longer in the sliding shutter 5 - so festgestelit of the sensor 7 non-presence of wood 2 - so the tray 5 returns to its original position Au and remains there until long wood 2 again to the longitudinal stop 51 out in the Loading 5 slips, or it is in this case of the cutting device 1, for example, a beep or light signal delivered or the saw unit 3 and the drive 55 of the oscillating tray 5 is turned off.
