Sweden-Sverige (SE) 7506262-0 (71) Ab. Haramars Mek. Verkstad, Box 33, 870 52 Nyland, Sweden-Sweden (SE) (72) Nils Erik Hellström, Nyland, Bengt Artur Berg, Bollstabruk, Sweden-Sweden (SE) (7 * 0 Berggren Oy Ab (5U) This invention relates to an apparatus for transporting timber of different grades or species to a inspection device or to a similar timber packaging device.

In such devices, it is necessary to temporarily store the different types or species of timber coming from the inspection device or the like, all of which are then transferred to the packaging device and a timber package is built, which is of uniform quality or type.

It is known to meet this requirement by arranging, after the inspection device or the like, several horizontal, superimposed transverse conveyors, each intended for a single quality or type, which are capable of temporarily supporting the total number of pieces of timber arriving on the transverse conveyor and required for a complete timber package. these are transported to the timber ply organizer and from there to the only existing packaging site of the packaging machine. A disadvantage of the known device is, in particular, that said transverse conveyor must have a considerable length, e.g. 50-60 m, in order to temporarily store the entire said quantity of timber, as a result of which the device becomes very space-intensive and only packs one package at a time. resulting in a considerable amount of time.

The object of the present invention is, on the one hand, to reduce to a very considerable extent the space requirement of the device in question between the inspection device or the like and the wood packaging device and, on the other hand, to increase the package production speed, and the main features of the invention become apparent.

The invention is illustrated by the exemplary embodiment shown in the accompanying drawings, which will be described in more detail below with its operation.

Figure 1 schematically shows a side view of a device according to the invention.

Figure 2 shows on a smaller scale a side view of a device according to the invention and a part of a timber packaging device.

Figure 3 shows a continuous timber packaging device of the part mentioned in Figure 2.

Figure 1 shows a conveyor part 1 of an inspection device, where the pieces of wood have been cut and inspected and where they have subsequently received a quality and length determination, after which the pieces of wood are ready for packaging. A vertical conveyor 3 is connected to said conveyor part 1 in a known manner, in which the endless chain or chains 4 have support levels 5 for supporting the pieces of timber 2. According to the invention, a number of horizontal, superimposed chain conveyors 6-10 are arranged on the side of the conveyor 3, each of which has its own adjustable stop member 11-15 · Each chain conveyor 6-10 is intended to receive from a vertical conveyor 3 and rollers 16-20 depending on the number of pieces of timber 2 of the same quality or species required to build a single-layer layer 2 'for the package of timber.

A horizontal belt conveyor 21-25 is connected to each chain conveyor 6-10, which runs intermittently and is of sufficient length to support two or more single-layer layers 2 *.

At the end of the latter conveyors 21-25 are arranged two receiving conveyors 26 and 27, which are height-adjustable independently of one another for connection to the conveyors 21-25. The receiving conveyors 26, 27 may be provided with retractors or friction generators (not shown) in order to move the timber upwards if necessary. The flap member 28 with the conveyor 29 is mounted on a pivotable horizontal shaft 30, which is right next to the conveyor 33 belonging to the timber packaging device, which conveyor is only partially shown. The flap member 28 can be adjusted to as many angular positions as there are conveyors 21-25, to adjust it substantially-directly in line with one of the two receiving conveyors 26, 27. The movements of the conveyors and other members are indicated by arrows. All conveyors are designed to transport timber in this transverse direction.

The operation of the device shown in Figure 1 is as follows. Individual pieces of timber 2 are transferred from the conveyor 1 to the support levels 5 and e.g. computer controlled arms 16-20 operate in such a way that one and the same 59771 4 timber quality, regardless of the order of quality, is transferred to each conveyor 6-10, e.g. quality "Kvinta" for conveyor 6, "wreck" for conveyor 7, "spare" for conveyor 8, "u / s" for conveyor 9 and "special" for conveyor 10. The stopping members 11-15 are then responsible for holding the pieces of timber on the respective conveyors 6-10 until the required number of pieces of timber is collected for one layer of the timber bundle, which is detected e.g. by a photocell device, after which the relevant stop member 2 is released so that the e.g., 21, the receiving conveyor 26 and the flap member 28 are set substantially i in the same line between the end of the conveyor 21 and the conveyor 33, after which all the single-layer layers on the conveyor 21 are conveyed via the conveyors 26 and 29 to the conveyor 33 for further transport to the packaging site.

The device shown in Fig. 2 is substantially similar to the device shown in Fig. 1, and Fig. 3 shows a wood packaging device connected to the device of Fig. 2, which has several packaging locations and is made mainly in accordance with Finnish Patent Application No. 752506, but some other embodiment may also occur.

Figure 2 shows a larger number of conveyors 31 with stop members 11 for forming single-layer layers and the same number of conveyors 32 to support a suitable number of single-layer layers compared to Figure 1. In this case, each spare wood species or species can be transported by a single pair of conveyors 31, 32 or by two or more pairs of conveyors 31, 32 simultaneously. The timber packaging device has a conveyor 34 provided with L-shaped forks 35 which take a single layer 2 'from the conveyor 33 and transport it to the packaging location 36-39 for the timber or species in question. Timber packages are marked 40-43 · By arranging the conveyors 32, 33 according to the invention and with the described implementation and operation, considerable longitudinal space savings are achieved, as this need is only one third of that required in known devices, and by placing a second receiving conveyor 26 or 27 e.g. in advance c 59771 in connection with one conveyor 32, while the single-layer layer is conveyed by another receiving conveyor 27 or 26 away from one of the conveyors 32, a high conveying speed is achieved, which is further increased so that the device according to the invention can cooperate with a packaging device so that filling can take place at several packaging locations while one or more packages are transported out. Thus, in known devices, the necessary interruption in the import of single-layer layers when the finished package is removed is avoided and the whole use can take place more continuously, which is important not only for packing speed but also for power consumption, especially for relatively high weights for conveyor and single-layer layers.

The invention is not limited only to the embodiment described and shown in the drawings, as this can be varied, in particular with regard to details, within the scope of the invention. The second receiving conveyor may be removed, but then the transport speed of the device decreases. Arrangements for the proper interconnection of all moving parts take place in a known manner. The drawings show the device in a so-called vertical plane, but since the length of the timber can be e.g. 5-6 m, there are of course several, e.g. five, such devices divided by the horizontal width of the plant.
