    The invention relates to an allocator for allocating sawn timber parts from a accumulation conveyor to a entrainment conveyor according to the preamble of claim 1.
    Allocation is a process step in woodworking in which cut wood pieces, such as sawn timber boards, are transferred from an uncontacted feed to a tied feed. In this case, the billet parts in the uncactivated conveyance are in the form of a piled-up film of juxtaposed sawn timber parts, the sawn timber parts being transferred by the feeder individually to a driver conveyor, with one sawn timber part to be assigned to each driver of the entrainment conveyor. Conventional feeders may here comprise actuatable rollers, lifting tables or star wheels which are in tact handing over individual lumber parts to the carriers of the carrier conveyor.
    The disadvantage of this is that when allocating the sawn timber parts must be greatly accelerated, and it often due to the different geometries and the inhomogeneity of the workpiece to different
    Accelerating movements of the sawn wood parts occurs because the sawnwood parts differ in physical properties from each other in parts, or a billet part is not completely detected by the feeder. As a result, there is no parallel guided movements of the sawn wood parts, which in the subsequent transfer into the carrier conveyor causes an incorrect storage and this must be corrected manually again. This leads to an increased susceptibility to interference in the area of the meter, especially as the number of clocks increases.
    The object of the invention is therefore to provide an arbiter of the type mentioned above, with which the mentioned disadvantages can be avoided, with which an allocation of sawn timber parts can be reliably carried out by a accumulation conveyor to a Mitnehmerförderer even at high clock rates.
    This is achieved by the features of claim 1 according to the invention.
    This results in the advantage that the allocation of sawn timber parts even at high cycle rates and associated with it also takes place at high accelerations reliably, since the individual sawn timber part is clamped in the allocation and thus limited in its freedom of movement. In this case, the billet part can be clamped by the two jaws and accelerated in this clamped state and passed on in order to the entrainment conveyor. By arranging the moving devices on both sides of the conveying area, lumber pieces of various sizes can be reliably clamped and thus allocated, even at high clock rates. Furthermore, since the moving devices do not interfere with the conveying area, a plurality of moving devices and jaws can be used without mutually blocking each other, whereby also a high clock rate can be obtained.
    The forcibly guided acceleration of the sawn timber parts results in a low susceptibility of the metering process and, associated with this, achieves a very high plant efficiency.
    The invention further relates to a dispensing system according to the preamble of claim 6 with this dispenser.
    Furthermore, the invention relates to a method for allocating sawn timber parts with a feeder according to claim 10.
    It is therefore also an object of the invention to provide a metering machine for sawn timber parts with which the mentioned disadvantages can be avoided, with which allocation of sawn timber parts from a accumulating conveyor to a driving conveyor can be more reliable even at high cycle rates.
    The advantages of the method correspond to the advantages of the allocator.
    The subclaims relate to further advantageous embodiments of the invention.
    It is hereby expressly referred to the wording of the claims, whereby the claims at this point are incorporated by reference into the description and are considered to be reproduced verbatim.
    The invention will be further described with reference to the accompanying drawings, in which only preferred embodiments are shown by way of example. Showing:
    Fig. 1 shows a first preferred embodiment of a dispenser system in side view;
    Fig. 2 is a part of the first preferred embodiment of the allocator system as an axonometric representation; and
    Fig. 3 shows a second preferred embodiment of a dispenser system in side view.
    Figures 1 to 3 show preferred embodiments of an allocator 1 for allocating sawn timber parts 2 from an accumulation conveyor 3 to a entrainment conveyor 4. An arbiter 1 is an apparatus in woodworking, in which cut pieces of wood, in particular cut and / or sawn timber boards, of an indexed conveyor, in particular in the form of an accumulation conveyor 3, in a clock-bound promotion, in particular in the form of a driver conveyor 4, transferred, with individual sawn timber parts are passed to targeted from the accumulation conveyor 3 and the carrier conveyor 4.
    It is provided that the distributor 1 has a first jaw 6 arranged on a first moving device 5 and a second clamping jaw 8 arranged on a second moving device 7, that a conveying area 9 is arranged between the first moving device 5 and the second moving device 7, and that the First jaw 6 and the second jaw 8 form a clamping unit 10 to clamp a sawn timber part 2 in the conveying area 9 and to transport it by a rectilinear movement of the first jaw 6 and the second jaw 8 in a clamped state.
    This results in the advantage that the allocation of lumber parts even at high rates and associated with it even at high accelerations takes place reliably, since the individual lumber part 2 is clamped in the allocation and thus restricted in its freedom of movement or the
    Allocation in the direction of movement is defined. Here, the billet part 2 can be clamped by the two jaws 6,8 and accelerated in this clamped state and ordered to the entrainment conveyor 4 passed on. By arranging the moving devices 5,7 on both sides of the conveying area 9, lumber pieces 2 of various sizes can be reliably clamped and thus allocated even at high clock rates. Further, since the moving devices 5, 7 do not engage in the conveying area 9, a plurality of moving devices 5, 7, 12, 14 and jaws 6, 8, 13, 15 can be used without mutually blocking each other. In this case, an increase in the clock rate can also be achieved.
    Further, an allocation system 17 comprising an accumulation conveyor 3 and a pickup conveyor 4 is provided, wherein the allocator 1 is disposed between the accumulation conveyor 3 and the entrainment conveyor 4 for transporting a lumber piece 2 from the accumulation conveyor 3 to the entrainment conveyor 4. The conveyor region 9 extends from the accumulation conveyor 3, where the sawn timber parts 2 are picked up by the allocator 1, to the entrainment conveyor 4, where the sawn timber parts 2 are released again from the distributor 1. In particular, the entrainment conveyor 4 may have a plurality of entrainment members 18, with one piece of cutting wood to be allocated per entrainment member 18.
    In particular, it can be provided that the accumulation conveyor 3 and / or the subscriber conveyor 4 are designed as cross conveyors, that is, transport the sawn timber part 2 transverse to its longitudinal extent.
    Further, there is provided a method for allocating sawn timber parts 2 to the feeder 1, wherein the sawn timber part 2 is clamped in a gripping area of the conveying area 9 between the first jaw 6 disposed on the first moving device 5 and the second jaw 8 arranged on the second moving device 7, wherein the conveying portion 9 is disposed between the first moving device 5 and the second moving device 7, whereby the lumber piece 2 is transported through the conveying portion 9 in a clamped state by a rectilinear movement of the first jaw 6 and the second jaw 8 and released again in a setting portion of the conveying portion 9.
    The jaws 6,8 are provided to clamp the lumber piece 2 between them and hold them therewith. The first jaw 6 and the second jaw 8 together form a clamping unit 10 which is intended to pinch a single lumber piece 2. Here, the first jaw 6 may have a first clamping surface and the second clamping jaw 8 have a second clamping surface, wherein at least in the clamping state, the first clamping surface is arranged parallel to the second clamping surface, and more preferably, the first clamping surface is arranged exactly opposite to the second clamping surface
    The first jaw 6 is arranged to be movable in a predeterminable manner by a first movement device 5, and the second clamping jaw 8 is arranged to be predeterminably movable by a second movement device 7. Here, in particular, the respective jaws 6, 8 may be fixedly attached to the respective moving device 5, 7, whereby the clamping force for the jaws 6, 8 are generated by the moving devices 5, 7 and transmitted to the lumber section via the jaws 6, 8.
    The clamping of the lumber piece 2 is particularly preferably by a straight relative movement of the first jaw 6 and the second jaw 8 to each other, more preferably, the two clamping surfaces remain parallel to each other.
    In particular, it may be provided that, when clamping, the clamping jaws 6, 8 move normally toward a surface of the sawn timber part 2, that is to say when they are clamped in, no lateral movement component occurs relative to the sawn timber part 2. This results in a controlled and well controllable entrapment at well definable points, without the sawn timber part 2 being already accelerated when being clamped in without being completely clamped.
    Furthermore, it may be provided that the lumber piece 2 is accelerated by the moving devices 5, 7 only after complete clamping by the clamping jaws 6, 8.
    Furthermore, it can be preferred that the clamping unit 10 has a predeterminable number of first clamping jaws 6 and second clamping jaws 8, and that the first clamping jaws 6 are arranged along a transverse extension of the dispenser 1 and move parallel to one another. In this case, the individual clamping jaws 6, 8 can be arranged, in particular, in each case on their own moving device 5, 7. The transverse extension of the feeder 1 is parallel to the longitudinal extent of the lumber section 2. As a result, a single lumber section 2 can be clamped by several jaws 6, 8 and reliably transported.
    Alternatively, it can be provided that the clamping unit 10 each comprise a first jaw 6 and a second jaw 8, which clamp in particular the cut wood part 2 in the center. Due to the central entrapment, the torques of the lumber piece 2 are kept low while accelerating. Such an embodiment is shown in FIG.
    Between the moving devices 5.7, the conveyor region 9 is arranged. The conveying area 9 is here the spatial area which is crossed by the cut timber parts 2 during transport. In this case, the handle area, ie the area where the feeder 1 clamps a single lumber piece 2, at a first end of the conveying area and the settling area, ie the area at which the feeder 1 releases the single lumber piece 2 again, the second end opposite the first end End of the conveyor area arranged.
    In particular, it may be provided that the moving devices 5, 7 remain in operation outside the conveying region 9, whereby a retracing moving device 5, 7 can not collide with a transported timber part 2.
    Preferably, it can be provided that - seen in operating position - the first moving device 5 is arranged below the conveying region 9 and the second moving device 7 is arranged above the conveying region 9.
    This has the advantage that, at least for the first movement device 5, it can be well predicted when the first clamping jaw 6 comes into contact with the sawn timber part 6.
    By the clamping unit 10, the lumber piece 2 is clamped in the conveying area 9 and accelerated and transported by a rectified movement of the first jaw 6und the second jaw 8 in the clamped state. The rectified motion in this sense means that the first jaw 6 and the second jaw 8 do not change the relative position and orientation during transport.
    In this case, it can be provided that in the picking area, by movement of the first movement device 5 and the second movement device 7, the first clamping surface and the second clamping surface can be moved toward one another into a clamping position in order to clamp a single timber piece 2 between the first clamping surface and the second clamping surface.
    Further, it may be provided, and that in the settling area, the first clamping surface and the second clamping surface are movable away from each other to a release position by movement of the first moving device 5 and the second moving device 7 to release the jammed sawn timber part 2 in the set-down area.
    After release of the lumber piece 2, the jaws 6, 8 are returned to the picking area by the moving devices 5, 7. By arranging the movement devices 5, 7 outside the delivery area 9, this return can be effected particularly quickly.
    Particularly preferably, it can be provided that the conveyor region 9 is substantially flat. This means that the sawn timber part 2 in the clamped state is accelerated and transported essentially in one plane, that is to say translationally along a straight line. This results in the advantage that during transport of the lumber piece 2 no torques arise which could liberate the lumber from the entrapment.
    The conveyor region 9 can be arranged substantially horizontally.
    In this case, the first clamping surface and the second clamping surface can each remain in a parallel plane in particular during transport of the sawn timber part 2.
    Particularly preferably, it may be provided that an acceleration of the cutting wood part 2 during dispensing takes place exclusively in the state clamped by the first clamping jaw 6 and the second clamping jaw 8.
    Particularly preferably, it may be provided that a driver 18 of the driver conveyor 4 moves in a set-down region of the conveyor region 9 at a driver speed, and that the clamping unit 10 releases the timber component 2 in the settling region in the case of a movement parallel to the driver 18.
    It can be provided that the driver 18 of the Mitnehmerförderers4 moves in the Absetzbereich the conveyor region 9 with the driving speed, and that the lumber piece 2 is accelerated in the clamped state to the Mitnehmernehmergeschwindigkeit and passed to the driver 18, and then from the first jaw 6 and the second jaw 8 is released. In this case, provision may in particular be made for the billet part 2 to already be ajar against the driver 18 before the billet part 2 is released from the clamping unit 10. As a result, the transfer of the sawn timber part 2 to the driver conveyor 4 can take place without an acceleration of the sawn timber part 2 in the un-clamped state.
    The accumulation conveyor 3 may be formed in particular as a conveyor belt and / or a roller belt, in which the individual sawn timber parts 2 to a stop, which is already in the conveyor area 9, in particular on the handle area arranged, transported. At this stop the cut wood pieces 2 abut each other and are dammed up.
    It may preferably be provided that the accumulation conveyor 3 has a gripping area of the conveying area 9, a sensor system operatively connected to the allocator 1, and that a clamping movement of the clamping unit 10 takes place only when a sawn timber part 2 is detected in the gripping area by the sensor system. Preferably, it can be provided in that the sensor system is operatively connected to a control device of the distributor 1 which controls the movement devices. The sensor system can be designed in particular as a light barrier system. By means of the sensor system it can be ensured that a sawn timber part is actually arranged in the picking area, which can be grasped by the clamping jaws 6, 8.
    Furthermore, it can be provided that the sensor system measures a height of a cutting wood part 2 arranged in the picking area in the operating position in the operating position, and forwards this measured height to the metering device 1, in particular the control device. By informing the height of the sawn timber part to be clamped in, the jaws 6, 8 can be targeted to the respective height, and lumber pieces 1 with a wide variation of the width can be quickly and reliably allocated.
    Furthermore, it can be provided that at least one of the clamping jaws 6, 8 and / or at least one of the moving devices 5, 7 has a pressure transducer. The pressure sensor may in particular be connected to the control unit. By the pressure transducer, a predetermined clamping force of the jaws 6,8 can be achieved.
    The pressure transducer can be arranged in particular in a damping element. In this case, it can be provided that the damping element is arranged between the first clamping jaw 6 and / or the second clamping jaw 8 and the associated moving device 5, 7.
    Particularly preferably, provision may be made for the accumulation conveyor 3 to comprise a movable accumulation retention hook 19 in a receiving area of the delivery area 9. Here, a lumber piece 2 is transported by the accumulation conveyor 3 until it rests against the accumulation conveyor retention hook 19.
    Then, this lumber piece 2 is clamped by the feeder and the pile-up retaining hook 19 is moved away from a retaining position, releasing the clamped lumber piece 2, which is then removed from the feeder 1, preferably horizontally. Thereafter, the accumulation retention hook 19 is again moved to the retention position to retain subsequent sawn timber portions 2 of the accumulation conveyor 3. Advantageously, the movable accumulation pawl retention hook 19 is such that the arbiter 1 does not have to lift the clamped piece of lumber 2 over the stop, which would generate a torque. By Stauförderrückhaltehaken 19 of the Anschlagweiters can be designed to be particularly high, whereby a piece of wood striking the stop piece with a larger height can not turn on the Anschlaghinweg.
    Alternatively, a fixed stop may be provided, with the feeder 1 lifting the billet part 2 over it.
    Particularly preferably, it can be provided that the first movement device 5 and / or the second movement device 7 are designed as a hinged arm 11. In particular, the first movement device 5 and / or the second movement device 7 can be designed as a kink arm with a pivot 20 between two arm segments. By providing articulated arms 11, the feeder can be made particularly versatile and used for a wide variety of differently shaped lumber pieces 2. Figures 1 and 2 show a preferred embodiment of the dispenser in which the moving devices 5, 7 are designed as articulated arms 11.
    The arm 11 may in particular be articulated at a first end and have the clamping jaw 6,8 at a second end.
    Furthermore, it can be provided that an axis of rotation of the rotary joint 20 runs parallel to the transverse extent of the allocator 1. In particular, provision may be made for the arm 11 to move essentially within a plane which runs normal to the transverse extent of the dispenser 1. Thereby, a plurality of movable arms 11 can be arranged along the transverse extent of the dispenser 1 without interfering with each other in the movement.
    The movement of the arms 11 can be achieved in particular by means of a servo control 21. The servo controller 21 may be controlled by the controller.
    Furthermore, it can be provided that the first movement device 5 and / or the second movement device 7 comprises a carriage 23 which can be moved in a predeterminable manner along a rail 22, and that the first clamping jaw 6 and / or the second clamping jaw 8 are arranged on the carriage 23 so as to be able to be weaned by means of a tracking element 24. The rails 22 can in particular run parallel to the conveyor area. The moving member 24 allows movement of the jaws 6,8normal to the direction of movement of the carriage 23. By the carriage 23, the moving device 5,7 can be particularly easily formed, wherein an actuation of the moving elements 24 is only necessary for clamping or releasing the cutting wood part. Fig. 3 shows a preferred embodiment of the dispenser in which the moving devices 5, 7 are comprised of carriages.
    Particularly preferably, it can further be provided that the distributor 1 has a third jaw 13 arranged on a third movement device 12 and a fourth clamping jaw 15 arranged on a fourth movement device 14, that the third clamping jaw 13 and the fourth clamping jaw 15 form a further clamping unit 16 in order to phase-shift it to clamp clamping piece 10 formed by the first jaw 6 and the second jaw 8 in the conveying area 9 and to transport it by a rectilinear movement of the third jaw 13 and the fourth jaw 15 in a clamped state. The further clamping unit 16 can in this case be arranged offset to the clamping unit 10 along the transverse extent of the allocator 1. The further clamping unit 16 can be operated analogously to the clamping unit 10. Through the further clamping unit 16 can be assigned per movement cycle of the allocator 1, an additional timber section 2, whereby even higher clock rates of the driving conveyor 4 are possible. InFig. 1, the further clamping unit 16 is shown in dashed lines.
