    101520253035Said known collecting devices are furthermore relativespace consuming, which is not least due to the need to stop and store pieces of woodduring the layering phase. Layer building devices that are smallerspace-consuming have the advantage that they can be installed and utilized within an existing onelimited building space.
    A first object of the present invention is therefore to provide a devicewhich makes it possible to form timber layers with a predetermined width at the same time asthe pieces of wood are constantly moving forward. A second object of the invention is toprovide a device that enables an improved control over the pieces of wood as wellduring the layer building step as the transfer step, i.e. in the step as a formed layerlifted from below by the transfer device's carrier plane for packing.
    These two objects of the invention are achieved by a device forLayer construction of pieces of wood which have the characteristics and characteristics specified inclaim 1.
    The basis for the invention is the insight that in the event that the pieces of wood do not need tostopped in any position during the layering process but can move forward substantiallymaintained speed while a layer of the desired width is formed, may occuracceleration and deceleration forces are minimized. As a result of the crochet pieces preservingits speed forward, and unlike prior art does not need to be accelerated from a standstill,the acceleration forces that affect a board layer that is accelerated up to are minimizedspeedthe transmission moment. Thanks to the use of a collection conveyor with doublesynchronous or the same forward as the transmission device belowalternately operating sub-conveyors, a very high laying rate can be obtained. Withdouble sub-conveyors, one can receive and collect a layer of timber at the same time asthe second conveyor can accelerate a previously formed layer to a speed adapted tothe speed of the transfer device at the handover of the layer.In the following, an embodiment of the invention is described in more detail withreference to the accompanying drawings in which;fl q¿ schematically shows a side view of a device according to the invention locateditself in a final sequence of a layer-building step on alayer-building conveyor, whereby a single layer of a certain width has begunacceleration to a speed synchronized to the speed at whichthe carrier plane of the transfer device moves forward the moment the layer is lifted from belowsaid carrier plane,å yes schematically shows a side view of the device according to Fig. 1 but located inan initial sequence of a layer building step, in which pieces of wood are successively transferredBesk P4130027OSEOO1015202530353from a feed path to the layer building conveyor to form a layer ofpieces of wood on this,Egg shows a plan view of the device shown in Figs. 1 and 2,fl qi shows a perspective view of a layer construction device in the present layercomponent layer conveyor, andFig. 5the layer-building conveyor, in an embodiment where said surfaces are arranged at different levelsshows a detailed enlargement of timber-bearing surfaces ofin height with a front higher part seen in the transport direction and a rear lower part as wellcoated with any elastomer that offers a substrate with relatively high friction.Referring to Figures 1 and 2, there is shown a device 1 for collecting pieces of wood2 to form timber layers 3. The device is intended to form part of a packer orproduction line for packaging of sawn timber for boards and has its special use inhandling of planed and thus relatively "slippery" wood. The device has the task of collectingup and form timber layers 3 of timber pieces 2 which are transported in their transverse direction.
    The pieces of wood 2 are assembled into layer 3 with the required number (s) of pieces of wood to achieve apredetermined width which in turn is adapted to the desired width of a finished onework package.
    In the figures, 10 generally denotes a feed conveyor on whichtimber pieces 1 are fed distributed with a gap “d” or a distance between them, with20 denotes a collection conveyor with the task of collecting and forming timber layers 3 ofa number of pieces of wood, with 30 denoting a height-adjustable carrier intended to be carriedstacked timber layers and arranged to move with the growth of the package incorresponding degree successively downwards until the package is ready, with 40 denoted onetransfer device as by means of a carrier plane 41, which is movable in a cyclic path and performsa reciprocating motion, transferring one layer 3 at a time by lifting from belowthe layer from the collection conveyor, bring the layer forward and lay it down on theand the lowerable carrier 30.
    The feed conveyor 10 comprises a number arranged next to each otherendless running transport element 11 or belts whose timber-bearing surface has a relatively small surfacefriction. The transport elements 11 move around a turning wheel 12 which is mounted on a horizontalThe impeller 12 stretchesthe collection conveyor in the manner best shown in Figs. 1-3, so that an intersection pointshoulder. one piece into and below the subsequentformed and pieces of wood 2 can be transferred from the feed conveyor 10 tothe collection conveyor 20. If Figures 1 and 2 are studied in more detail, it should be statedthat the conveying plane of the feed conveyor 10 slopes down towards the horizontal plane by oneangle denoted o which in this case is approximately 5 °. Feed conveyor 10 speedV, measured in the number of pieces of wood 2 per unit of time, can be adjustable as desired by means ofBesk P4130027OSEOO1015202530354a variator coupled to a drive shaft 13 shown in the drawings in Fig. 4 forthe conveyor element of the feed conveyor 11.
    The collection conveyor 20, which in the conveying direction of the timber 2 is located afterthe feed conveyor 10, comprises a number next to each other across the feed directionarranged collection segments 21, in this case seven pieces, cf. Fig. 4.Referring further to Fig. 4, each collection segment 21 has a pair ofa first and a second sub-conveyor 20A, 20B each comprising an endless conveyortransport element 22 consisting of a chain arranged to run in an endless path over a, irear drive wheels 23The transport element 22 thus runs in a plane which is parallel to the transport direction of the timber.the transport direction of the timber, and a front impeller 24, respectively.
    As best seen in Fig. 3, the first and second sub-conveyors 20A, 20B runtransport elements parallel to each other, but located laterally offset fromeach other in the longitudinal direction of the pieces of wood. The first and second sub-conveyor20A, 20B, in each collecting segment 21, each has an upper active part of the chain whichis guided on a rail 25. All collecting segments 21 in a row are onsubstantially the same level in height and thus forms a common substantially horizontaltransport plan. The first and second sub-conveyors 20A, 20B are provided along their peripherywith respective counter-means 26A, 26B with the task of offering stopping action against a frontedge of a piece of wood which, passing a handover point P1, is transferred fromthe feed conveyor 10 to the collection conveyor 20. With respect tothe direction of rotation of the sub-conveyor 20A, 20B is located behind each counter member 26A, 26Ba timber-bearing surface 27A, 27B. This timber-bearing surface 27A, 27B is located on a levelslightly above the upper edge of the chain and suitably comprises some material with relatively high frictionfor example, some elastomer. The plumbing means 26A, 26B consist of block-like elevationseach extending radially from the central center of the transport element. The first andthe recipient means 26A and 26B, respectively, of the second sub-conveyor 20A, 20B are eachattached to the peripheral outside of the transport element and moves in a path accompanying onerespective transport element 22.
    Fig. 5 shows the timber-bearing surface 27A, 27B in an alternative embodiment andarranged as two timber-bearing sections 27: 1; 27: 2 located at different levels in height wherebya front portion 27: 1 seen in the transport direction is located at a slightly higher level Y1 than a onerear section 27: 2 at level Y2. Depending on the dimensions of the wood and the total width ofa formed layer of wood, it may be necessary in some applications with particularly wide layers toarrange the timber-bearing surfaces at different levels 27: 1; 27: 2, this to minimize the risk ofpieces of wood 2 simultaneously rest on both the first and second sub-conveyors 20A, 20B.
    As best seen in Fig. 4, the first and second sub-conveyors 20A, 20B are driven offa respective electric motor 28 with adjustable speed, the first and second respectivelyBesk P4130027OSEOO1015202530355the respective speeds of the sub - conveyors, denoted by V1 and V2 in Figs. 1 and 2, canvary independently. A first and a second separate drive mechanism, eachincludes a drive shaft 29 and transmission, ensures that the series of the first sub-conveyors 20Aof counter means 26A and the 2OB series of the other sub-conveyors, respectivelycounter means 26B can move synchronously in the feed direction of the wood and be ona common line X1, X2 across the feed direction. It is understood that the relativethe distance between these two transverse lines of opponent means 26A, 26B ithe feed direction of the wood can be varied by accelerating or decelerating each otherfirst and second sub-conveyors 20A, 20B.Referring to Figs. 1, 2 and 3, the transfer device 40 used is shownto transfer one layer at a time by lifting the layer from belowthe collection conveyor, move the layer forward and lay the layer down on the height andlowerable carrier 30. The transfer device comprises a carrier plane 41 which by meansparallel transfer arms, indicated only by dotted lines in the figure, arearranged to move cyclically in orbit by performing a reciprocating motion.
    Since this type of transmission device with cyclically movable carrier planes has been around for a long timeknown, for example from SE 434 167 C2, their function will not be described in more detailIn Fig. 1, the carrier plane 41 is set in a position such as a continuation ofthe collection conveyor 20 and, while performing a linear movement from a lower onestandby position to an upper position illustrated by the arrow, lifting a layer 3 from below andtransferring the layer from the collection conveyor 20 to the height-adjustable carrier 30. IFig. 2 shows the support plane in a position above the height-adjustable carrier 30 and immediately beforeit moves downwards and backwards as illustrated by the arrow to deliver the layer 3 on the heightand the lowerable carrier 30.
    The present collecting device works as follows:Referring to Fig. 1, a number of pieces of wood 2a, 2b - 2n are fedone-piece divided, ie. with a gap or a distance between them, forward onthe conveying element 11 of the feed conveyor 10 at a speed V1 and further downagainst the timber-bearing surface 27B of the second sub-conveyor of the collection conveyor 2020B. The receiving means 26B of the sub-conveyor 2OB is in this case in a receiving position inwhich the trailing edge of the receiving means 26B is located in a first handover point P1, i.e.the point where the feed conveyor 10 and the collection conveyor 20transport means 11, 20B intersect. On the first sub-conveyor 20A is onepreviously formed timber layer 3: 1.
    When the leading edge of the first piece of wood 2a contacts the second sub-conveyor20B counter means 26B, said counter means begins to move forward by onespeed V2 which is so adapted relative to the speed V1 of the feed conveyor 10 to whenBesk P4130027OSEOO1015202530356rear edge of said first piece of wood 2a reaches the first handover point P1 docksfront edge of a subsequent second piece of wood 2b with rear edge of the first piece of wood2a and so on. This successive docking is best shown in Fig. 2. Thanks tothe velocity V2 of the counter-member 26B of the second sub-conveyor 20B is lower thanthe feed conveyor speed V1, i.e. V2one-piece divided pieces of wood 2a and 2b to be reduced to zero.
    As best seen in Fig. 2, the pieces of wood 2a, 2b will successively form onelayer 3: 2 whose leading edge abuts supportively against the second sub-conveyor 20Bcountermeasures 26B, close together at the front and rear edges and resting on saidsub-conveyor timber bearing surface 27B. Thanks to the fact that some slipping is allowed to happen againstthe transport element 11 of the feed conveyor 10 strives for the 3: 2 pieces 2a, 2b of the timber layer- 2n to always be close to each other.
    When the last piece of wood 2n of a number of "n" pieces of wood that are part of a layer 3: 2 witha predetermined width arrives at the first handover point P1, it startsfirst sub-conveyor 20A. This first sub-conveyor 20A is now empty because it is onepreviously not shown step delivered left layer 3: 1 to the transfer device 40 for depositionof the layer on the height-adjustable carrier 30. The first sub-conveyor 20Athe counter means 26A then moves forward and around the drive wheel 23 so that it is behindthe last piece of wood 2n in the layer (which in principle again corresponds to the position in Fig. 1).
    At the same time, the second sub-conveyor 20B is accelerated to a speed corresponding toor so adapted to the speed V1 of the feed conveyor 10 that a gap is formed betweenthe last piece of wood 2n in the formed layer 3: 2 and a subsequent piece of wood intended toform a first piece of wood in a subsequent layer 3: 3 (not shown). When back edge of last piece of wood 2nin layer 3: 2 with margin passed the handover point P1, layer 3 is accelerated up to aspeed V3 (see Fig. 1 where this layer 3: 2 is in a position corresponding to the layer 3: 1)which is synchronized to the speed V4 at which the carrier plane of the transfer device 4041 moves obliquely upwards to lift the layer from the collection conveyor 20. The formedlayer 40 carrier plane 41handover point P2 located above the center of the front of the sub-conveyor 20A, 20B24 andthe transfer step. When3: 2 is transferred to the transfer device at a secondturning wheel at which point the two movements intersect throughoutthe whole layer 3: 2 transferred tosub-conveyor 26B sub-conveyor means 26B to high speed designated V5 until it reachesthe carrier plane 41 is acceleratedthe waiting position below the front of the feed conveyor 10.
    For the sake of the matter, it should be pointed out that the above-described counter-means 26A, 26B do notare necessary in order to achieve the technical effect referred to in the invention. Theshould be understood that the risk of pieces of wood slipping or shifting uncontrollably underneaththe process of layering is minimized to an even greater extent by the countermeasures.
