Method and apparatus for placing intermediate strips on top of a layer in drying loads of different lengths Förfarande och anordning för att bringa mellanribbor pa ett lager i torkningslaster av olika längd 5

The invention relates to a method and an apparatus for sawing stripping machines in which drying loads of different lengths are made.

10 In known device solutions, e.g. according to SE publication 367 382, the necessary slats are retrieved for the drying load from the storage locations of the dosing conveyor. The position of the slats in the load is determined by the storage locations in question. The disadvantage of these previously known device solutions is precisely the fixedness of the storage locations and the fact that the strip pick-up device 15 is not able to automatically move the intermediate slats to the desired locations in the drying load. Such automatic handling of the slats and the determination of the position of the intermediate slats would be a basic precondition for the formation of a flexible and fast drying load.

The object of the invention is such a method and apparatus with which it is possible to automatically move the spacers to the desired positions in the drying load. It is also an object of the invention to provide a method and apparatus capable of forming a desired size and constructed in a desired manner; drying room loads automatically.

The object of the invention has been achieved with a solution in which it is realized to form an apparatus in which the bar coupling means of the bar retrieval device can be moved automatically after the bars have been picked up from the storage locations of the distribution conveyor.

30

The method according to the invention is mainly characterized in that in the method only the horizontal position of some intermediate strips is changed, while others remain in the position determined by the storage stations.

The apparatus according to the invention is mainly characterized in that the apparatus comprises means by means of which at least some of the means for engaging the strips are displaceable from the horizontal to adjust the horizontal position of the strips with respect to the timber batch, preferably the drying load.

According to the invention, a method has been implemented by means of which the position of the strips with respect to the drying load can be adjusted automatically. In the method according to the invention, the position of the gripping hook of one or more bars is adjusted in relation to the drying load and the frame part which can be moved vertically. The method according to the invention uses a device solution in which a second frame part, which is movable horizontally with respect to it, is operatively connected to the vertically movable frame part. Said second frame part also comprises gripping means for the ribs, i.e. the transfer rod and the pick-up hooks, as well as the abutment part. The transfer rod is still movable relative to the second frame part by a separate actuator. The device solution according to the invention works automatically. When the distribution conveyor implementing the 15 storage stations has stopped, the strip pick-up device moves next to the storage stations. The movement of the transfer bars is performed automatically. And the pick-up hooks are placed under the bars. The slats rise slightly from their horizontal position with the ends of the pick-up hooks sloping. The movable first frame part 20 is then lowered vertically downwards according to the prior art. During this horizontal movement, movable bar gripping means, i.e. pick-up hooks: can be automatically programmed in advance to the desired horizontal positions. In this way, the desired position of the intermediate strips 1 with respect to the drying load is achieved. This horizontal movement ·.: 25 is performed before the frame section is lowered, eg to the top of the dryer load. - on top of the timber layer. Finally, according to the prior art, a drop of the spacers is performed on the upper surfaces of the horizontal parts of the hooks.

The invention will now be described with reference to some preferred embodiments of the invention shown in the figures of the accompanying drawings 30, to which, however, the invention is not intended to be exclusively limited.

Figure 1A is a partial schematic view of a method and device according to the invention for placing intermediate strips on top of a layer of timber in drying loads of different lengths. The apparatus 10 comprises a pick-up device 11 by means of which the intermediate strips can be picked up from the storage stations 15 A, B, C, D, E, F, G. The intermediate strips 12 are picked up from the storage stations A ... G by lifting the movable frame part 14 of the pick-up device 11 so that the strips 12 of the storage stations A, B, C settle on the pick-up hooks 13 or similar coupling means. The arrow Lx indicates the vertical displacement of the frame 14.

The slats 11 are mounted by means of the actuator 16 in the desired horizontal position and the frame 14 is lowered, whereby the slats 12 can be left in the desired position on the top timber layer K, as shown in broken lines in Fig. 1A.

Thus, with the device according to the invention, it is possible to carry different amounts of dry-bed loads, and according to the invention it can always be ensured that a spacer 12 is obtained at the ends of the dry-bed load.

A part of the pick-up hooks 13 can be directly connected via the transfer rod 15 to the first frame part 14, whereby the strips 12, E, F, G of the storage stations 13 picked up by said pick-up hooks 13 can only be placed in the horizontal position in the timber package below. Some of the pick-up hooks 13 can again be moved according to the invention by means of an actuator 16. In this way, it is possible to obtain a spacer at the ends of the drying load loads of different lengths.

Figure IB is shown in Figure IA of the top view of Figure IA, the direction of arrow D katsantosuuntaan. The second horizontally movable frame part 30 15 is adapted to move in the guides with respect to the first frame part 14.

Such movement is provided by an actuator 16, preferably a cylinder device.

As shown in Figure 1B, the frame 14 may comprise a somewhat symmetrical structure 35 with respect to the central axis Xa. The frame halves 14a and 14b are connected to each other by intermediate parts 14c. Correspondingly, the second horizontally movable frame parts 15a and 15b can be connected to each other by an intermediate part 15c. The actuator 16 may be located on a string on either side of the axis Xx and may engage one of the frame parts 15a or 15b. Only one actuator 16 is required. Of course, an embodiment of the invention in which there are two or more actuators 16 is also possible.

Figures 1A and 1B show in dashed lines all the stations to which the intermediate strips 12 are moved after they have first been picked up by the pick-up device 10 from the storage stations A, B, C ...

Figures 2A and 2B show the implementation of storage stations A, B, C and the associated distribution conveyor 19 of the apparatus 10. The distribution conveyor 19 implements storage stations A, B, C, D, E, F, G. The distribution conveyor 19 comprises one or more, preferably two, adjacent endless chains 20 passed through folding wheels 26a, 26b. Each chain 20 comprises hooks 21 or the like into which the spacers 12 are placed. The spacers 12 are fed from a dispenser 22 comprising a conveyor 23 and abutments 24. The abutments 24 engage gravity fed spacers 12 from an oblique table 25. The arrows Lg and L4 show the passage of the spacers 12 from the dispenser 22 to the hooks 21 of the distribution conveyor 19.

When the bar 12g on the hook 21 has reached the rear folding wheel 26b of the distribution conveyor 19 and the hooks 21 downstream of the chains 20 are provided with the bars 12 25, the distribution conveyor 19 is stopped automatically and the bars 12 are removed from storage stations A, B, C, D, E, F, G through.

When the slats 12 have been picked up by the pick-up device 11 from the storage stations A, B, C ... 30, a horizontal transfer is made (arrow L2) so that the slats 12a, 12b, 12c of the storage stations A, B and C are placed at the desired places on the upper wood: goods layer. . The frame 14 is then placed on top of the upper timber layer Kx of the drying load K. Thereafter, the actuators 18 of the transfer rods 17 are used to detach the intermediate ribs 12a-12g from the pick-up hooks 13 of the transfer rods 17.

Figure 3 shows the actuators connected axonometrically to the frame part 14 for moving the first frame part 14 and the second frame part 15 and the transfer rod 17. The view is partly schematic and principled. According to the state of the art, the rib pick-up device 11 may comprise abutment parts 25, by means of which the intermediate strips 12 can be placed in a precise position with respect to the drying load K. The abutment portions 25, as shown in Figure 3, are attached to both the first frame portion 14 and the movable second frame portion 15. An actuator 16, preferably a cylinder, either a pneumatic or hydraulic cylinder, is adapted to move the second frame portion 15 20 horizontally with respect to the first frame portion 14.

Figure 3 schematically shows the retrieval of the intermediate strips 12a, 12b and 12c from the storage station A, B, C. The frame part 14 is raised by means of the actuator 30 to the level of the intermediate strip 12a, 12b and 12c in the storage station A, B, C. The transfer rod 17, which is articulated with respect to the second frame part 15, is moved by the actuator 18 to such a position that the pick-up hook 13 in the transfer rod 17 passes under the bar 12. The end 13a of the pick-up hook 13 may be wedge-shaped, so that the bar 12 rises and rests on the horizontal portion 13b of the pick-up hook 13. The actuator 30 can then lower the frame 14 downwards. According to the invention, the second frame part 15 with its pick-up hooks 13 can be placed in the desired horizontal position (arrow with respect to the drying load K by moving the second frame part 15 with the transfer rod 17 and its pick-up hooks 13 by means of the actuator 16. The pick-up hooks 13 are provided with 35 ribs 12a, 12b, 12c The actuator 30 continues to lower the frame part 14. When the top layer Kj of the load K has been reached 7 86984, the actuator 18 moves the transfer rod 17 and the pick-up hooks 13 back to its original position, in which case the bar 12 on the horizontal portion 13b of the pick-up hook 13 eventually falls off the horizontal portion 13b 5 of the pick-up hook 13. The bar 12 is then brought into the desired position with respect to the drying load K.
