    15 '20 25 30 35 2 down the top or last layer of timber laid while the transfer arms are withdrawn from the layer. In this part it should be understood that here too the adjoining member must be removed so that it is out of the way before a new layer of timber can be placed on the top layer of timber in the elevator device, which of course delays the laying of the timber layers.
    Accordingly, said adjoining means is also substantially limiting the speed at which a device of the type described above can be run and consequently how quickly and efficiently timber can be packaged.
    In summary, it can be stated that the capacity of hitherto known devices for stacking and spreading and formation of timber packages in so-called package layers, in addition to the above-mentioned adjoining means, are also limited by the way in which the spreader and layer spreader means move relative to each other since spreading of spruce by means of spreader spreader presupposes an interruption in the discharge of the timber layers by the spreading means.
    These circumstances also entail limitations partly with regard to the possibilities of utilizing spreader pavers together with continuously working laying bodies, and partly the possibilities of utilizing joint drive for both layer spreader and spreader spreader in a plant for stacking and forming scattered timber packages.
    From SE 415 879 a device is known which, in order to form a timber package, has a linearly movable litter feed member, which grips the rear end of the litter, i.e. with a substantially cantilevered engagement, in a working stroke, the litter feeds onto the base of the stacking device simultaneously with the forward and / or return movements of the layer laying member, so that the litter and timber layers perform an opposite relative movement during at least part of the process. The gripped litter is dropped on the upper side of the timber layer when the litter feeding means has reached a predetermined position in over the timber layer. According to the document, the mutual movement between the wood layer laying means and the spreading layer means takes place at different levels and without contact between the beams and the wood layers during the spreading.
    The object of the present invention is thus to design, based on prior art, a device for forming sprinkled timber packages in which the litter-laying means is arranged so that the timber-bearing transfer arms of the lay-laying means can be run at a higher speed and that the total capacity of the device can thereby be substantially increased.
    This object of the invention is achieved with a method which exhibits the features and characteristics stated in claim 1. A device for carrying out a method according to the invention is characterized by the features stated in claim 6 and is proposed in claim 13 a method of using a litter. Additional features and advantages of the invention will be apparent from the subclaims. the insight underlying the invention is that capacity increase can be obtained by improved control of pieces of wood in a last laid layer while the transfer arms are retracted and the wood layer is scraped off. . Improved control can be achieved by bringing strands, which are gripped at their rear end to be laid down on top of a layer of timber, during a part of their closing movement into co-operation towards the top of a last laid layer of timber so that, like a tumbler member in a retaining manner , cooperate with the timber layer while the transfer arms of the layer laying member are withdrawn from the layer. Thanks to improved control of pieces of wood in a recently laid layer of wood, the speed when laying pieces of wood in packages can be significantly increased. In one embodiment, a litter feed member included in the spreading device is formed with a gripping member which can grip a litter in a cantilevered manner in its rear end seen from the timber stack and from an upper position, moving vertically down towards a stacking base. Delivery of the litter, during the vertically downward movement takes place in a closing part, with the feed member gripping the litter, and with a certain applied force in cooperation with the top of pieces of wood in a layer of wood which for placement is in a position above the stacking base while the layer laying means is pulled back. back from said timber layer. Thanks to the fact that the litter is gripped in a cantilevered manner at its, in relation to the rear laying device, rear end, a significant advantage is also obtained compared with the hitherto known type of litter laying devices which are either of the type which grips the litter about its central center or its front and rear end, namely that the layering means can begin its laying movement of the next layer of wood over the stacking table at a substantially earlier stage because the scattering means is out of the way of the layering means even if it is in a position where it still grips the litter and presses it down against the last laid the working layer in the stack. In the following, an exemplary embodiment of the invention will be described in more detail with reference to the appended claims; Figs. 1a - 1c schematically show side views of a device for stacking and spreading wood pieces according to the present invention, viewed during different working steps and in interaction between a layer laying means included in the device for placing wood layers in a stack on an elevator device and a part included in the device. litter handling device equipped with a litter depositing means for placing litter on the top of a timber layer placed in the stack; fi g; 2, wsaren ädovv dävß ismü ängs m fl enlh fl i fi g. a current magazine included in each such cassette, and a scattering mechanism for conveying a single litter from the underside of the magazine to an upper retrieval position next to the spreading cassette in which retrieval position the spreading means can grip the litter at its rear end; O: leg besk 111031 111115 besk.docx 10 15 20 25 30 35 4 fi go shows a perspective view of the spreading cassette included in the spreading handling unit with the spreading magazine and the spreading device included therewith; fl g¿ shows a cross-sectional view of the current magazine included in the spreading cassette, viewed along the line IV - IV in Fig. 3; Fig. 1 shows a cross-sectional view of a part of an IV - IV considered in the present device in the fig. strön; Fig. 1g shows a side view of a separate straw depressing means which, in an alternative embodiment, may be included as a part or a complement to the present device.
    In Figs. 1a-1c show in side views a device for stacking and spreading of layered timber pieces according to the present invention, viewed during different working steps in the respective figures. Said device comprises a layer laying means 1 intended to from a loading position in a so-called layer former (not shown), i.e. a device with the task of collecting pieces of wood conveyed from a feed conveyor to layer 2, carrying the layers out to a relief position in a hoisting device which is generally indicated vertically in a vertical direction on which the layers are delivered. Since the layer laying means 1 as such is well known, this layer laying means 1 will be shown. The elevator device 3 is intended that on a so-called stacking pads not to be described in more detail with only a front portion of the 3a carrying the stacked timber layers so that the last laid layer 2 or the top layer is at a predetermined level. The present device also includes a litter handling device 4 which has the task of, at a suitable rate and perpendicular to the longitudinal direction of the timber pieces, placing the litter 5 between the timber layers stacked on top of each other.
    For each layer of straw 5 and timber laid, the stacking substrate 3a is lowered a distance corresponding to the sum of the thickness of straw 5 plus timber layer 2. The layer laying means 1 comprises in a known manner a number of parallel forward transfer arms 6 or support planes which are in practice evenly distributed along the transversely transported the length of the pieces of wood. The transfer arms 6 are arranged to move cyclically during the following one path and arranged to lift layer 2 of timber pieces from below in said loading position (not shown) and then, in a substantially horizontal feed direction indicated by the arrow 6a, transport the layer over the lifting device 3. movement cycle is, as illustrated by the curved arrow 7, the transfer arms arranged to move a distance substantially vertically downwards and then retracted in a linear horizontal return direction indicated by the arrow 6b while the wood layer is scraped off from the transfer arms. The stripped timber layer 2 is laid directly on the stacking table 3a of the elevator device 30 if it is the lowest layer in a package or when a timber layer has previously been laid, on the top timber layer in the elevator device.
    According to the present invention, the litter handling device 4 is located directly above the elevator device 3 while said layer laying means 1 is located at one side thereof. The litter handling device 4 includes a series of litter handling units spaced apart and located in a row above the elevator device 3, perpendicular to the length of the pieces of wood in each timber layer 2 of the elevator device, in each such litter handling unit a bed laying means 10 is included. in relation to the rear end of the layer laying means 1 is intended to move perpendicular to the direction of movement 6a, 6b of the transfer arms 6 of the layer laying means 1. Alternatively, it can be said that the direction of movement of the bed laying means 10 moves parallel to position 11 by means of the bed laying means 10 for being placed on top of a timber layer 2 laid on the elevator device 3. The bed laying means 10 is guided towards the layer laying means 1 for laying bed 2 on suitable layers laid on the stacking base of the elevator device 3 at a suitable rate 3a. To scrape the timber layer 2 from the transfer arms 6, there is a retaining member 3c which acts against one side edge of the layer acting as an abutment and thereby retains the layer over the elevator device while the transfer arms 6, indicated by the arrow 6b, are retracted from the stack towards an upstream device. layer former (not shown). The task of laying the bed 10 is thus to lay bed 5 on the top layer delivered in the elevator device 3 before the laying arms 6 transfer another layer 2 to the timber stack.
    Referring also to Fig. 3, the litter handling device 4 comprises in its upper part a litter-carrying cross conveyor 20 of the carrier type and formed with chains 21 running between wheels 22, and with which conveyor litter 5 is retrieved from a magazine 23 not shown in the figures for transport forward in its transverse direction along a path extending directly over the elevator device 3 and along which path the struts are transported in the transverse direction resting on a substrate 24 formed by a number of parallel rails extending in the transport direction. The litter-carrying cross-conveyor 20 thus transports the straw 5 resting on the support plane 24 directly over and in a transverse direction towards the longitudinal direction of the timber layers 2 stacked on the elevator device 3, which is best seen from Figs. 1a-1c. Below the litter-carrying cross-conveyor 20 and directly above the elevator device 3, a number of litter cassettes 30 are arranged at a mutual distance from each other in a row along the transport direction of the cross-conveyor 20, marked with the arrow 20a. Each litter handling unit includes such a litter cartridge 30.
    With particular reference to the detail enlargement in Fig. 2 and Fig. 4, each such spreading cassette 30 comprises a spreading magazine 31 in which spreading 5 is stored, stacked on top of each other in the transverse direction to the length of the pieces of wood in the wood layers 2, i.e. the straws are stored in said hopper in the same direction as they are fed on the above-carrying stray-carrying cross conveyor 20. In a portion above each stray cassette 30, the carrier plane 24 is sectioned and thus provided with an opening 25 down towards a respective iron cassette. Each iron cassette 30 is provided in its upper part with a guide device which comprises a number of flaps 32 which are distributed along the length of a litter 5 and which flaps are adjustable via a respective power cylinder 33 into and out of the flow of litter 5 fed on the litter-carrying cross conveyor 20. By means of the flaps 32, if necessary, the current 5 can be deflected from the cross conveyor 20 and guided down into the current magazine 31. In each current magazine 31 there is a measuring means 34 in the form of an optical sensor which, by reading a level, checks the number on each other. stacked strands 5 in the magazine. When the number of straws 5 in one of the stray cartridges 30 and the current magazine 31 is less than a predetermined number, the measuring means 34 sends a signal to a control equipment not shown in the figures which in turn commands the power cylinder 33 to adjust the flap 32 in such a position that the straws 5 are steered down in the magazine that currently needs to be refilled.
    In Figs. 1a-1c and Fig. 3, respectively, a straw discharge means 10 is shown which in the transport direction of the transverse conveyor 20 is arranged downstream, next to each. spreading cassette 30 and which spreading feed means has the task of retrieving a spreading 5 from the spreading magazine 31 and then lowering the spreading to a position on top of a timber layer 2 laid on the elevator device 3. The spreading feeding means 10 comprises a gripping means 10a intended to grip it in relative to the elevator device 3 seen the rear end of a litter 5, so that the litter held by the gripping means is in a substantially horizontal position. The gripping means 10a is supported on a carriage 10b which, as illustrated by the double arrow 10c, is by the action of a power cylinder 10d vertically movable up and down along parallel rails 10f between an upper defined pick-up position 11, in which the gripping means can grip one discharged from the magazine 31 litter and lower defined leaving position 12 in which the litter can be delivered on a timber layer 2 laid on the elevator device 3. The gripping member 10a extends horizontally from the carriage 10b and is arranged to grip by means of a series of arranged grippers 10g comprising movable clamping arms the rear end of a litter 5 which is adjusted in said upper retrieval position 11 next to the litter cassette 30. In the lower leaving position 12 the litter 5 is delivered to the top of a timber layer 2 last laid on the timber stack by the gripping means 10a being adjusted in a non-gripping position . According to the present invention, the litter 5 gripped by the gripping means 10a is kept oriented substantially flat parallel to the timber layer 2 placed on the elevator device 3 and, when in its lower position, is brought into such interaction with the upper side of the timber layer 2, as indicated by the arrow C in Fig. 1c, that the pieces of wood are kept fixed in the layer, while the layer laying arms 6 are withdrawn from the layer indicated by the arrow 6b. The gripping member 10a has compressed air-driven force cylinders (not shown) which, when actuated, can switch the clamping arms acting against each other to grip local portions of the rear end of the litter.
    As shown in Figs. 3 and 4, each current magazine 31 is delimited by front and rear walls 10h and 10, respectively, not shown in more detail in the figures. 10i formed by plates which are transverse to the struts 5 stored in the magazine 31 and which plates between them form a path which allows the struts, under control, to move downwards gradually as the strands are taken out from a strut opening 31a of the lower end of the magazine 31. The current magazine 31 is provided with a number of substantially L-shaped pair-active current transfer arms 32 which are arranged to block in a retracted lower position the current withdrawal opening 31a which is located below the current magazine 31. Upon activation, the current transfer arms 32 have the task of transmitting, one at a time, a litter 5 located at the bottom of the web to said upper retrieval position 11 next to the litter cassette 30 in which position the litter can be gripped between the gripping arms 10a of the gripping member 10a. Each spreader transfer arm 32 has a first and a second leg bone 32a and 32, respectively. 32b. The first leg leg 32a of the spreading transfer arm 32 is fixed at one end at the end of a pivot shaft 33 which extends centrally through the spreading cassette 30 and is pivotally mounted therein for rotation about an axis substantially parallel to the direction of movement of the layer laying member 1, or actually the transfer arms 6.
    The second leg bone 32b of the litter transfer arm 32b is provided at its free end with a support surface 36 having a recess corresponding to the shape of two adjacent elongate sides 5a, 5b of a litter 5 so that a litter resting at its ends on the support surfaces 36 of two pairs of active litter transfer arms 32 , can be supported in a supportive manner from the lower outlet position blocking the current outlet opening 31a under the current magazine 31 to the upper retrieval position 11 next to the current magazine 31 by lifting in an arcuate path upwards.
    Rotation of the rotary shaft 35 takes place by the action of a double-acting power cylinder 36 arranged to actuate a lever 37 fixed to the circumference of the rotary shaft, the strut 5 being transmitted through the following a circular arcuate path at a radial distance from the rotary shaft.
    As best seen in Fig. 4, in order to be able to transmit a beam 5 at a time from the opening in the lower part of the magazine, the second leg bone of the beam transfer means is provided with a concave or substantially arcuate cam surface 35a on its side facing the axis of rotation. This concave cam surface 35a has been given from said pivot axis 35 such a radius or shape that the cam surface is allowed to sweep past or slide against a subsequent litter in the magazine so that this subsequent litter 5 and other straws remain in the magazine, while the two cooperating transfer arms carry a litter. on the support surfaces between them lifts this litter to the upper litter delivery position 11 next to the litter cassette 31. The litter transfer thereby becomes automatic and means that the litter 5 can be transferred at high speed from the magazine 21 to the litter feeding means 10 and further down to a position for co-operation with an on the elevator device 3 laid timber layer 2 while the transfer arms 6 of the layer laying means 1 are pulled out of the timber stack.
    Fig. 5 shows a cross-sectional view of layer laying means viewed along the line IV - IV in Fig. 1c. The laying arms 6 of the layer laying member 1 are in this case inserted in a position in a gap 40 which is delimited between two timber layers 2, 2 'stacked on top of each other. Between said timber layers 2, 2 ', struts 5 are laid out which extend in the transverse direction relative to the timber pieces in the layers. In order to improve control of pieces of wood in a last laid layer while the transfer arms are retracted and the wood layer is scraped off, ie. in order that the transfer arms 6 should not affect a last layer of timber laid on the stack and thus that the pieces of timber should vest or end up in disorder, the laying arms 6 have been given a height "h1" which is less than the height of the litter 5, i.e. h <H.
    With reference to the circled detail enlargement in Fig. 1c, a height h2 of the gripping member 10a movably facing each other has similarly been given a height h2, which is so selected in relation to a roof or seat defined by an upper part of the gripping member against which the upper elongate side 5c of the gripped litter is intended to support that the clamps extend only a limited distance downwards along the two parallel vertical sides 5a of the litter. Due to the limited downward extension of the clamping arms 10e, it is ensured that the interaction between the litter 5 and the top of a last layer of timber is laid while the laying arms 6, illustrated by the arrow D in Fig. 1c, are pulled out of the stack exclusively by the litter, ie. without risk of affecting the clamping arms 10e. Fig. 6 shows a side view of a spreading means generally designated 50 and which, in relation to the layer laying means 1, is located on the opposite side of the elevator device 3. This spreading means 50 is intended to be used as a complement to the device described above, especially in lean timber, makes it possible to drive the timber layer-bearing transfer arms 6 of the layer laying means 1 at an even higher speed. The stray depressing means 50 comprises a parallel guide mechanism 51 which is supported on a frame 52 and which parallel guide mechanism in turn carries an elongate stray depressing finger 53 arranged to pivot in vertical plane parallel to the direction of movement of the laying member 1 towards the elevator device 3. More specifically, move along a relatively flat circular arcuate path between a depressed position advanced, in which the free part 54 exerts a predetermined depressing force against the top of a bed 5 laid on a timber layer placed in the elevator device and a reversed rear rest position, in which the free part 54 is in position where it is one removed from a position above the elevator device.
    This is achieved above all by the straw depressing means 50 at its return stroke backwards from its bed 5 depressing position substantially moving along a flat path with a large radius substantially parallel and in the same direction as the direction of movement of the laying means 1 when depositing a layer of timber on the stack 3. One of the advantages of said parallel extending return stroke, from the current depressing position, is that the current depressing means 50 can be retained in its effective current depressing position for a relatively long time before it must be removed so that it is out of the way before a new layer of timber can be placed on the elevator device 3. As shown in Fig. 6, the outermost part 54 or finger of the straw depressing member 50 could essentially be retained in its straw depressing position until carried new timber layer 2, moving in the directional arrow 6a, is in a position mit t over the elevator device 3 and ready to begin its downward movement for laying on the stack. Furthermore, it should be understood that the movement distance of the spreading device 10 from the upper retrieval position 11 next to the spreading cassette 30 down to the leaving position for delivering a litter on top of a timber layer 2 laid on the elevator device becomes relatively short, which has a positive effect on capacity.
    The present device for stacking and spreading wood layers has the following working methods: In Fig. 1a the present device 1 is shown in a position where the laying arms 6 of the layer laying member 1, indicated by the arrow, transport a wood layer 2 in the direction of the stacking base 3a 3a for laying the elevator device 3. The bed laying means 10 of the litter handling device 4 are in this case in their upper retrieval position 11 next to the litter cassette 30 and with the gripping member 10a gripping the rear end of a litter 5 which is discharged from the underside of said litter cartridge . Fig. 1b shows the device in a position where the litter held by the gripping means 10a of the straw discharge means 10 moves down to a position above the stacking base 3a of the elevator device 3 by being moved linearly downwards in a first part of a working stroke to the lower leaving position 12 for delivery on the upper side of a timber layer 2 previously laid on the elevator device 3 ”. The movement in said first part of the working stroke thus takes place in a direction substantially perpendicular to the direction of movement of the laying member 1 and with the litter moving in parallel with the stacking base 3a of the elevator device 3.
    In Fig. 1c the transfer arms 6 of the layer laying member 1 have moved a further distance, a further new timber layer designated 2 "being taken from the loading position not shown in the figures and being advanced to a position slightly above the laying table 3a of the elevator device 3. is in this case in a position where it is laid down on the elevator device 3 finally delivered by the transfer arms 6, in a linear horizontal movement, indicated by the arrow 6b in Fig. 1a, being retracted while the timber layer 2 is scraped off from the transfer arms. 10a does not grip the litter as soon as it contacts the timber layer 2 laid on the elevator device 3, but retains its grip on the litter in a position in cooperation with the timber layer for a predetermined period of time. More specifically, the litter 5 which is held free in its rear end is brought of the gripping means 10a of the straw discharge means 10, in a second part of 0: leg be sk 111031 111115 besk.docx 10 15 20 10 the working team to cooperate with the upper side of the timber layer 2 in order to thereby stabilize the pieces of timber in the top or last laid timber layer while the transfer arms 6 are withdrawn from the layer.
    As a result, the previous need for separate tumbler means, especially for lean timber in this type of device, is eliminated. Due to the fact that the gripping means 10a of the bed discharge means 10, in a cantilevered manner grip the litter 5 about its, in relation to the layer laying means 1, seen as the rear end and uses the litter as a supporting means to stabilize the timber pieces the last laid layer 2 eliminates the risk of the timber pieces tipping over or fall into disarray when the transfer arms 6 are withdrawn from the timber layer, as illustrated by the arrow 6b in Fig. 1c. In addition, due to the gripping means 10a of the straw feeding means 10 gripping the rear end of the litter, the previous problems of the gripping means 10a of the straw feeding means 10 having to completely disappear or be taken out of the way before a new layer of timber can be delivered to the top timber layer are avoided. In the rear position, as best seen in Fig. 1c, a new layer of wood can be retrieved and advanced to a position substantially above the hoisting table 3a of the elevator device 3 before the gripping means 10a must release the grip on the litter and return to its upper retrieval position 11 next to the spreading cassette 30.
    The present invention is not limited to what is described above and that shown in the drawings, but can be changed and modified in a number of different ways within the scope of the inventive concept stated in the appended claims. 0: leg besk 111031 111115 besk.docx
