The invention relates to a method for sawing machines which operate as combination machines at different times, stripping fresh sawn timber for drying and at different times stamping and packing dry sawn timber, in which method a transverse conveyor is used the ends have a stop response, after which there are stamping devices or other similar devices in the plane of the plane they define, especially for handling dry lumber, the transfer members of the latter longitudinal conveyor being adjustable to at least two height positions.

With the mechanical support of the sawmill industry, sawmills have introduced stripping machines, which use intermediate strips to make packages for drying, as well as packaging machines, which unpack said packages and make compact packages of timber for sale.

Due to the fact that the mentioned machines are expensive and because many of the same functions take place in them, the so-called combination machines for alternating the handling of dry and alternating fresh sawn timber. In this connection, reference is made to FI patent No. 35,523.

In said machines, it has become difficult to transfer timber at different stages of work. The handling conveyor must move or not move tracks, move every second, or move all tracks.

The object of the present invention is to provide a method which avoids the above-mentioned problems and provides a simple method.

In order to achieve the above and later objects, the method of the invention is mainly characterized in that the transfer members of the latter longitudinal conveyor in its second height position are adapted to move the pieces of timber wherein said transfer members of the latter longitudinal conveyor are lowered to such a lower position or the pieces of lumber coming into it are otherwise retained so as not to move substantially longitudinally at the latter longitudinal conveyor.

The present invention has realized the advantage of using a second transverse conveyor already inherent in the devices in question, so that it can implement the various modes of operation required in the combination machines in question. In addition, the invention takes advantage of the known fact that the pieces of timber are generally on two different planes on the transverse conveyor in question.

By applying the method of the invention, simple and reliable device solutions are obtained which do not take up a large space.

In the following, the invention will be described in detail with reference to some application examples of the invention shown in the figures of the accompanying drawing, to the details of which the invention is not limited.

Figure 1 shows a top view of an apparatus implementing the method according to the invention in a mode of operation in which a flat packet is made at both ends.

Figure 2 shows, in a manner similar to Figure 1, a mode of operation of the device in which both ends of the pieces of timber are stamped and the pieces of timber are made into a flat package at only one end.

Figure 3 shows a mode of operation of the device according to the invention in a manner corresponding to Figures 1 and 2, in which the pieces of timber are stamped only at one end and a flat package is made only at one end.

Fig. 4 shows a section for the latter longitudinal conveyor in the mode of operation corresponding to Fig. 1.

Fig. 5 shows the operation of the latter conveyor according to Fig. 2, corresponding to Fig. 4.

Fig. 6 shows Figs. 4 and 5, respectively, of the operation according to Fig. 3.

The transverse conveyor 10 shown in the figures is of a conventional construction, the conveyor chains of which have grippers 15 between which the pieces of timber are transported. in connection with the cross conveyor has a first longitudinal conveyor 11, which carries the timber pieces in the direction of arrow B. The response 12a determines the equatorial line L 1 -L 2. After the stop 12a, a first stamping device 14a is known per se. This is followed by a second cross conveyor connected longitudinal conveyor 13, which moves the timber pieces in the direction of arrow C against the response 12b. After the stop 12b there is a second stamping device 14b. The stop 12b determines a second straight line. The second longitudinal conveyor 13 is followed by packing devices known per se, in which the figure shows transfer arms 20 which transfer a certain part of the timber mat to the package formation.

The latter longitudinal conveyor 13 consists of a transfer roller 16, at least part of the rollers of which are used. The transfer rollers 16 are mounted on a frame or frame 17 which can be raised by a hydraulic or pneumatic cylinder so that the transport plane of the roller 16 can be moved relative to the transport planes of the transverse conveyor 10 for later purposes.

The lumber pieces a, b are dispensed transversely to the chain conveyor 10 by means of a single dosing device, so that there is only one piece in each conveyor chain between the slots 15. The conveyor 10 is known per se and has a second conveyor loop 18a carrying lumber high every other 18b low.

When the machine, according to Figs. as the rollers 16 rotate, the pieces a move endwise over the second stop 12b of the chain conveyor 10 against the straight line I ^ -I ^ Ϊ and the second pieces b continue to advance while maintaining their position in the transverse direction and their other ends remain in the straight line L ^ . In this way, the thinned layer K 1 used in the ribbing is formed (Fig. 1).

For sale, dry lumber is usually stamped at one or both ends. Prior to stamping, the pieces are often leveled to produce a clean wood with a good stamp. The cutting saws are then arranged before the stamping machines 14a, 14b. Cutting saws are not shown in the figures, and cutting and / or stamping are hereinafter referred to as stamping for brevity.

When the device is intended to package and simultaneously stamp both ends of the pieces of lumber, the roller 16 'is at such a height (Fig. 5) that it carries the pieces a' and b 'to be transported on both low and high chain links 18a, 18b and moves them all according to Fig. 2. from one end to the other edge of the chain conveyor in the straight line I ^ -L ^. The ends of the pieces a ', b' are conventionally stamped by a stamping machine 14a, 14b placed on each edge of the chain conveyor 10.

If only the other ends of the pieces of timber are to be stamped during packaging, the rollers 16 "are adjusted to such a height (Fig. 6) that they do not touch the high and low chain pieces a", b "and thus do not move the pieces at all ends, as illustrated in Figs. 3 and 6.

The latter method can also be performed in such a way that the rollers are stopped, in which case a third height position is not required or the movement of the part is prevented, e.g. by an overhead presser or accessories which are raised above the surface from below.

The roller 16 can be raised and lowered and the desired positions obtained at any time
