The invention relates to a method for arranging the intermediate strips of layers of timber packages, for example to promote and / or keep dry timber, in which method on the means supporting the ribs, which are reversible or movable in the way of the ribs.

The invention further relates to an apparatus for applying the method of the invention, in which the distribution of spacers entering a timber package is carried out by a delivery conveyor .

When drying timber, transverse spacers are used between the layers, which allow drying as the air flow passes between the layers. The intermediate strips are thin and 6391 5 narrow pieces of timber, usually made of wood, which are placed between the layers depending on the length of the timber. The timber packages thus formed are made with grooving machines that have been known for several decades. Partitions are also used in packages made of dry or planed timber, where the main function of the partitions is to keep the wood spare package together. These packages are also made on the above-mentioned machines.

The package is usually made by transferring layer-width timber mats on the barn arms of a stripping or packaging machine, e.g. as disclosed in Fi Patent No. 42188, to a parchment elevator, which always descends one layer until the package is completed, after which it is moved away from the elevator.

The elevator returns to the up position and the execution of the next packet begins.

Previously, the spacers of the timber package were put in place by hand, later the use of bar magazines was started, from which the bottom bars were dropped on the top layer of the package.

As the power of the stripping machines increased, the use of strip distribution conveyors began, with which the strips were brought to the appropriate mutual distance transversely above the layer from where they were lowered onto the layer.

With regard to the state of the art related to the invention, reference is made, by way of example, to SE Patent No. 225,851 and Fi Patent No. 46247. Said Swedish patent already discloses a stripping method and device comprising a distribution conveyor with a series of support arms articulated to the conveyor chains, whose support parts downstream of the distribution conveyor chain are directed in the opposite direction to the main transport direction of the distribution conveyor. The disadvantage of this known device is e.g. the fact that the dosing of the intermediate strips on the support arms of the distribution conveyor and the equipment required here become complicated and prone to interference.

The method of said FI patent No. 46247 is mainly characterized in that the spacers brought above the timber package are lowered onto the timber packages by means of bottom-picking pick-up members which, when raised, take over the they leave spaces. In said patent, the distribution conveyor uses support hooks, the support parts of which are directed in the opposite direction to the main direction of the main conveyor of the distribution conveyor.

In connection with the method and device of the invention, various methods and devices known per se can be used in the transport and dosing of timber and intermediate strips for package formation. As one example of these methods, reference is made to U.S. Patent No. 4,067,455 (corresponding to Fi Pat. No. 760624).

However, previously known methods and devices are relatively complex and expensive, and their operation has become a bottleneck in limiting the efficiency of modern high-performance stripping machines.

In a dryer load, it is very important that the spacers overlap at exactly the same points, as the dryer load can weigh up to 30,000 kg. If the spacers are not at each other between the layers, the pieces of timber will become incorrect as they dry.

An essential observation for the invention is that if the slats are dropped onto the layers of wood goods, the slats bounce and settle obliquely or aside. Thus, the spacers must be brought onto the floor in a controlled manner.

In order to avoid the above-mentioned drawbacks and to achieve the objects of the invention, the method of the invention is mainly characterized in that the strips adjusted in the above-mentioned manner are pressed from above by pressers, said members supporting the strips turning and / or moving out of the way of the strips and adapted to guide and guide the strips. on both sides, guiding, without compression grip or bottom support, into place on the top layer of the timber package, after which the pressers are raised to the upper position and the method steps defined above are repeated.

The device according to the invention, in turn, is mainly characterized in that said transmission members consist of pressers arranged at certain points of the bar division and which are attached to a superstructure which can be moved vertically by means of power devices. support spacers above the timber package and which are turned or moved aside when placing the presser spacers down on top of the top layer of the timber package, and that said pressers comprise a downwardly open, fork-like guide without pliers.

Figure 10 shows the printer part separately.

The device shown in Figures 1, 2 and 3 comprises a feed conveyor 10,11 and a distribution conveyor 13,14,16. The feed conveyor consists of conveyor chains 10 and swivel wheels 11, which are driven by a distribution conveyor via a chain 12. Syöttökul-

II

The 5 63915 jet 10,11 feeds the intermediate strips to a distribution conveyor consisting of conveyor chains 16 arranged between the swivel wheels 13 and 14 and driven by a motor 15. Attached to the chains 16 of the distribution conveyor are arms 33 at intervals determined by the intermediate division, to which the pivotable support hooks 30 according to the invention are later connected in a more detailed manner.

Above the distribution conveyor 13,14,16 there is a frame structure 17 made of beams, to the middle horizontal top beam of which a hydraulic cylinder 18 is connected. Said frame is laterally guided by rollers 24. In the lower part of the vertically movable frame there are horizontal beams 22 to the lower side of which pressers 23 are attached at distances determined by the spacer. There are two or more printers 23 in parallel for each intermediate strip.

Swivel hooks 30 with a counterweight 31 are connected to the arms 33 of the conveyor chains 16 by means of articulation pins 32. From the feed conveyor 10,11, intermediate spacers Rq are dispensed on the support hooks 30 in a manner known per se.

Figure 5 shows the arrangement of the packaging elevator and the barn arm devices in connection with the device according to the invention. As is known per se, the packaging elevator comprises vertical columns 27, on which the elevator support arms 25 are supported by means of rollers 26, which step downwards as the wood package accumulates layers ^ 1, P2 '^ 3 ^ ne' 'and there are transverse spacers R. Latojavarret 28 are per se known and projecting in the direction of arrow B on the package provide a package of one layer at a time P Q R stickers on.

The operation of the device according to Figures 1,2,5,6 and 7 and an implementation of the different steps of the method according to the invention will now be described with reference to Figures 4A, 4B and 4C. The distribution conveyor has rested on the upper layer P1 of the package to be completed on the intermediate rail series Rq on its support hooks 30 at the points required for the intermediate rail division, and the distribution conveyor stops at this position. After this, the action of the hydraulic cylinder 18 of the horizontal beams 22 and connected to the printers 23 is moved in the direction of arrow C, down to the supporting folding hooks 30 in Figure 4B to the position 30 'of the counterweights 31' increases. The beam 22 'is relatively high speed in the direction of the arrow C, so that the stickers q' remain in the printers 23 'controlled on until the beams 22' attached to the pressure of 23 "are about the topmost layer of the timber against the upper surface of P ^. The support hooks 30 return to the horizontal position when pressed by the counterweights 31. After the method step of Figure 4C has been carried out, the bars 22 'return to the arrow direction B into the open position of the hydraulic cylinder 18 of the impact and then, the delivery conveyor 16 delivers the intermediate strip over a series of q latojavarsien 28 bring a new timber layer, and the steps described above are repeated.

The embodiment of the invention according to Figure 3 differs from that described above in that the distribution conveyor chains 16 do not have support hooks but only grippers 33a which move the set of spacers above the timber package so that the spacers slide along the support plane or support rails 35. The support rails 35 have hatches formed by arms 30a hinged by articulated pins 32a. The arms 30a are either provided with counterweights as described above or sprung so that they remain in the closed position even when the spacers Rq are on them. When the operation of the device has progressed to the step shown in Fig. 3, the distribution conveyor stops and the spacer strips R 1 come on the support arms 30a. Thereafter, the pressers 23 attached to the arms 25 press and guide the intermediate ribs as the arms 30a recede out of the way under suspension or counterbalanced as described above. The pressers 23 place the spacers R 1 on the uppermost layer of timber as described above, after which the pressers 23 return to their upper position, and the next set of spacers R 1 is dispensed at the support arms 30a.

According to Fig. 8, the chains 16 of the distribution conveyor are provided with support hooks 30b which are fastened with articulated pins 32b to the cantilever flanges of the support hooks 16. The support hooks 30b are provided with springs 31b which are so rigid that the intermediate ribs Rq remain in the support of the support hooks 30b, but the support hooks 30b give way to the position 30b 'when the pressers 23 press the intermediate ribs Rq from above.

It will be appreciated that the pressers 23 and the support hooks 30, 30a, 30b are not at the same point in the longitudinal direction of the intermediate ribs R 1. It is preferred that the printers press the spacers quite close to the support hooks or arms so that the spacers, which are often relatively thin, do not bend too much or break.

Figure 9 shows a particularly preferred embodiment of the invention, in which the pressers 23a are connected to their suction systems through an opening 36 which communicates with a suction channel 35. The suction pipes 35, 36 are arranged inside the beam 22a. The suction system has control devices which control the suction to act in the openings 36 by means of the sills when the pressers 23 move downwards according to Fig. 4B and press the intermediate strips Rq past the support hooks 30. The effect of suction is particularly important after the support effect of the support hooks 30 has ceased. The effect of suction is adapted to cease when the spacers have come on top of the top layer of timber, after which the printers begin to rise. The effect of the suction ensures that the intermediate strips Rq remain under the control of the pressers 23 even when the acceleration of the downward movement of the pressers 23 is less than the acceleration of the ground traction.

Figure 10 shows a more detailed structural example of the press members. The press members have lower flanges 37 corresponding to the upper surface of the uppermost layer of timber and upwardly inclined flanges 38 associated with the lower flanges 37, which act as guides so that the intermediate ribs R are guided under the press members. The press members 23 have an upper part 39 by which it is fastened to its support beams 22. In addition, the press members have, if necessary, an opening 40 through which the suction acts as described above.

The following are claims within the scope of which the various details of the invention may vary within the scope of the inventive idea.
