    15 20 25 30 35 2 because it adversely affects the capacity of the packer. It should be understood that as short transport paths and trajectories as possible are what each designer strives for, not least because of the mass forces acting on moving transfer arms. Due to said randomly occurring defects in the upper part of the wood pile, there is always a risk that a single piece of wood in the upper part of the wood pile gets stuck and follows out when the laying pianos' laying arms are retracted from the wood pile, whereby wood pieces in the layers risk overturning or falling over. .
    An object of the present invention is therefore to provide a device for transferring wood layers which makes it possible to eliminate the problems which may occur in cases where the formed wood package has form defects. Another object of the invention is to provide a device which makes it possible to increase the capacity of a parcel paver.
    These two first objects of the invention are solved by a transfer device for timber layers which has obtained the features and characteristics stated in claim i. The insight underlying the invention is that a carrier plane which is self-adjusting and can adapt to such shape variations which may occur in a pile of timber, is obtained by enabling each of the adjacent laying grooves which together form a supporting pile, that during the part of the movement cycle where the supporting plane and thus a supported timber layer which is lowered for laying is lowered on the top of a pile of timber. , to assume a kind of "floating flame" by disengaging from the pipe travel connection with the lifting mechanism in such a way that any of the laying arms is raised in its lowering travel downwards upon contact with an elevated portion of the top of the timber package while the lifting mechanism and other . When the lifting mechanism has reached a predetermined lower lowering position, the laying arms are again put in force-transmitting connection with the lifting mechanism, after which the laying arms are pulled away from the timber package.
    In the following, the invention is described in more detail with reference to the accompanying drawings, in which; Figs. 1A-1C schematically show a side view of a device for transferring timber layers according to the invention in different stages of work steps performed in a stacking cycle and transferring timber layers from the feed conveyor to an elevator device on which superimposed layers form a timber pile; gg ggg soematically shows a cross-sectional view of the device according to the invention viewed along the line il-ll in tig. 1A and at a stage during laying of a timber layer on a timber pile which is under construction, the timber pile at the top deviating from an ideal desired shape because it has an elevation at its right rear end edge; g gg schematically shows a cross-sectional view of the device according to the invention viewed along the line lll ~ ill in Fig. 1A and illustrating how a http: lldms.zaccocom / sitesiseICase / i11243361412Û5385 / P412Û5385SEÜÛ / P412O__2012_SE 21 10 15 20 25 30 35 3 release device consisting of a lifting cylinder with lockable piston rod, in disengaged position allows the laying arms to be self-adjusting by being stopped by contact with the upper side of the timber package while the lifting mechanism continues its downward movement; In the figures, an input conveyor 1 is generally indicated by 1 on which pieces of timber are fed in their transverse direction on chains 2. In direct connection to the output end of the input conveyor 1 denoted by 3, one of a number of uniform and individually movable support planes 5 is moved in sequence. Each such support plane 5 is arranged by means of parallel laying arms 9 arranged next to each other to move cyclically in a path in a sequence one after the other, where each acts as a respective transfer device between the discharge end 3 of the feed conveyor 1 and an elevator device 10 included in a packer. the figures not shown in the program unit or computer are arranged to control and monitor the movements of the various units.
    Figs. 1A - 1C schematically show a side view of a device according to the invention in the various working steps performed in a stacking cycle for transferring a layer of timber pieces from the feed conveyor 1 to the elevator device 10. Since the series of cyclically successive carrier planes 5 included The present transfer device is identical, for the sake of simplicity only the function and design of a single one of these carrier planes with associated drive systems will be described in more detail.
    Fig. 1A shows the carrier plane 5 in a first stage of its cyclic movement during which a layer 12 is being built on the same directly from the feed conveyor 1. As soon as a predetermined number of pieces of wood have been transferred to the laying arms 9 of the carrier plane 5, which takes place by means of the carrier 2 of the feed conveyor 1, the support plane 5 is set in forward movement along its guides 11 and in over a pile of timber 13 which is gradually intended to be built on the elevator device 10.
    Fig. 1B shows the support plane 5 in a second stage of its cyclic movement, the support plane having been lowered to a position above the stacking table 8 and the formed timber stack 13, so that the last applied piece of timber in the layer with its outer edge is slightly next to a abutment 14 of the elevator device 10.
    Fig. 2 shows the support plane 5 in a third stage of its cyclic movement during peeling of the layer, the support plane being in a position where it is pulled back away from the timber stack 13 and moved backwards on the guides 11 to a starting position under the feed conveyor 1. Again with reference to Figs. 1A-1C, each support plane 5 is formed by a number of adjacent laying arms 9 (see also Fig. 2), which are slidably arranged along a guide 11 pivotally arranged around a point 20 and are supported on the respective guide 11 by each carriage 22 with at least two impellers 23 on the upper side of the associated guide and at least one abutment wheel 24 on the underside of the same guide. In order to assign movement along the carriage 22 and thus the laying arm 9, the carriage 22 is connected via a link 25 to hupv / amszacco.com / siies / se / case / i1124asc / 41205385 / P41205385SE00 / P41205385SE00m2012-1 1 - O9w121. a drive mechanism 26, comprising an endless chain 27 or the like, which is arranged around the sprockets 28, one of which is fixedly connected to a drive shaft 29. This drive shaft 29 forms part of a drive mechanism 26 which is common to all cyclically in a path moving support plane 5. Regarding the support plane 5, all laying arms 9 for said support plane are intended to be displaced synchronously back and forth on said respective guides 11. For raising and lowering the support plane, the guides 11 are pivotable about their common storage point. By means of a lifting mechanism 30 which comprises an eccentric arm 35 which, for performing a lifting and lowering movement on the guide 11, is attached to a shaft 36 and is assigned a rotating movement of a drive wheel 37, which drive wheel in turn receives movement from a drive chain 18 only partially indicated in the figures. The shaft 36 is common to each of the mechanisms which lifting and lowering act on a respective guide 11 for the laying arms 9 in a support plane 5. If especially Figs. 2 and 3 are studied in more detail, the latter should be realized, i.e. that the lifting mechanism 30 comprises a lifting unit for each guide 11 with the task of creating a lifting and lowering movement for the laying arm 9 which is displaceable on the guide 11. As shown in Fig. 2, a number of such adjacent laying arms 9 with associated guide 11 form said support plane 5. The other support planes not shown in the figures are of course designed in a similar manner.
    The above described constitute all essential known technology.
    The present invention differs from the prior art in that it comprises a release device 40 arranged for each laying arm 9 which consists of a pneumatic lifting cylinder 41 with associated piston rod lock 42 which thus forms a switching means with which the release device can be moved between a released suspension position and a locking position. A pneumatically driven lifting cylinder 41 functions excellently as a spring means, whereby spring force (the cylinder's internal compressive force) can be varied by selecting a suitable medium pressure which is connected to the side of the lifting cylinder which is pressurized during lifting, generally called plus side.
    The lifting cylinder 41 is movably connected to the lifting mechanism 30 and arranged to be moved between a lower transport position relative to the lifting mechanism in which the laying arm 9 allows transfer of a layer of pieces of wood from the feed conveyor to the elevator device 10, an upper spring position in which the laying arm 9 is relative to the lifting mechanism 30 and can be driven downwards towards the lifting mechanism when overcoming the compressive force offered by the medium, and a holding position which can be taken in any position along the stroke of the lifting cylinder 41 and in which holding position the piston rod is locked to the cylinder and thus also the laying arm 9 in its lifting direction. relative to the lifting mechanism.
    With the release device 40 adjusted in the upper suspension position, the pressure of the medium which is led in on the positive side of the lifting cylinder is chosen so that when the laying arm 9 is unloaded, i.e. when it does not carry a load of pieces of wood, the lifting cylinder offers a lifting force that is sufficient httpJ / dms.zacco.com/sites/se/Case fl1124380 / 41205385 / P412Ü5385S E00 / P4 1 2Û53S5S EÛÛ ____ 2Û1 2-1 'l- 09__m121 109 besk o 2G 25 15 35 5 5 for lifting the extension arm 9 to an upper end position relative to the lifting mechanism 30. With the release device 40 arranged in its disengaging spring position, any of the extension arms 9 can be stopped from lowering travel when in contact with the upper package of the timber package. .
    As can be seen from Figs. 1a-1c, the lift cylinder 41 with coil rod assembly 42 is positioned so as to act between the free end of a guide 11 and the eccentric arm 35 of the lifting mechanism 30. The piston rod lock 42 comprises in a manner known per se a spring-loaded clamping element which is arranged to lock the bar rod in the axial direction by frictionally engaging therewith. The piston rod lock 42 can be released with an actuating means which is adjustable via a pressure medium. Thanks to the clamping element, the coil bar can be locked in any axially projecting position. As soon as a pressure medium is supplied, the clamping element releases its frictional engagement with the piston rod and the piston-cylinder device can return to the desired position. For example, an axially projecting position, ie. a starting position. This type of device has been well known for a long time, for example made by SMC; type C95N 850-100-0 and will therefore not be described in more detail.
    As mentioned above, by selecting the appropriate pressure on the lifting side of the lifting cylinder 41, the discharge arm 9 can be relieved from exerting any weight against a piece of wood which it is suspended against lowering in the timber pile. The media pressure is selected so that the lifting force of the lifting cylinder as soon as the laying arm has been relieved of the weight of the timber layer 12. That is, as soon as the timber layer is laid down and resting on the straw on the timber pile 13.
    With particular reference to Figs. 2 and 3, the device operates as follows: Fig. 2 shows a support plane 5 formed by a series of five parallel laying arms 9A-9E together carrying a layer of timber 12 intended to be placed on a pile of timber 13. During loading with the support plane in connection with the lowering end 3 of the feed conveyor 1 the lowering movement, the lifting cylinders 41 of the uncoupling device 40 are in their lower transport positions, in this position the laying arm 9 is locked in its lowering direction relative to the lifting mechanism 30. in their upper suspension layers. In this position the laying arms 9 can assume a floating position along a predetermined range of movement or play in their lifting direction relative to the lifting mechanism, which range of movement is essentially determined by the stroke of the lifting cylinders 41. Due to the weight of the timber layer, however, the lifting cylinders 41 are not able to lift the laying arms 9, but said lifting cylinders remain in their lower bottom positions. The laying arms 9 are consequently at substantially the same level in height and are thereby moved by the action of their respective lifting mechanisms 30 in a common lowering movement downwards for laying the timber layer on the timber step 13. http: lfdmszacco.comlsitesfse / Case / t 1 124330141 2Û4Û5 ' P412Û5385ENÛO_2Q1 2-1 'l- 09 __._ 121109 besk o requirementsdocx 10 15 20 25 30 6 If Fig. 2 is studied in more detail, it should be seen that the upper rear edge of the timber stack 13 is not linear in the horizontal plane but curves upwards so that it is seen in the figure to the right. the end of the pile of timber is slightly higher than the left. When the lowering movement 5 continues downwards, the laying arm QE which is seen on the far right in the figure will first hit the timber stack 13. Correspondingly, other laying arms QA-QD from right to left in the figure will eventually contact the upper rear edge of the timber joist 13 as a result, the deposited layer will strive to be formed against a previously laid layer on the stack 13 and thus obtain a resemblance in all substantially curved shape. This curved shape of the laid timber layer is illustrated by the dotted contour line 12 ”. Thanks to the movable connection of the release device 40 to the lifting mechanism 30, each of said laying arms 9 is stopped as they contact the upper rear edge of the timber tape 13 while the lifting mechanism continues its lowering travel downwards which is illustrated by the force arrows 45 in Fig. 3.
    When the lifting mechanism 30 has reached a predetermined lower lowering position, the lifting cylinders 41 of the disengagement device 40 are adjusted to their hollow positions by means of the lever bar 42 in which they are locked in their tilting direction to the lifting mechanism 30. More specifically, the lifting cylinders 41 can be adjusted. in practice this is done by ceasing the supply of pressure medium to the coil closure lock 42. Thereafter, the extension arms 9 of the support plane 5 are pulled away from the timber package 13 by the action of the drive mechanism 26. The extension arms QA-QE may here be at substantially different levels in height, depending on the position in which they are stopped upon contact with the previously laid timber layer on the stack 13 below lowering travel downwards. Before the carrier pianist 5 following its cyclic travel path is moved up to a position for receiving a new layer of pieces of wood adjacent to the discharge end 3 of the feed conveyor 1, the lifting cylinders 41 of the release device 40 are moved so that they are in their lower transport positions. will be at the same level in height. Thanks to the invention, a device is obtained for transferring timber layers from an feed conveyor to a height-adjustable stacking table which is self-adjusting to molds which can occur during the addition of a timber stack.
    The thawing 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 framework of the thawing tank specified in the following claims. u; - »», ~ »~>. ~ -. ~ ~ ~ - @ - ~. httpj / dms_zaococomlsiteslsefCase fl11243801412 Û5385 / P412Ü5385S EÛÛ / P412Û5385SEÜCL2Û1 2-1 'i- O9M1211O9 besk o kreddoox
