The invention relates to a method for arranging an external rotation of a drying wagon moving in a transverse position in a sawn timber dryer, in which method empty drying wagons are brought on the first tracks transferred other tracks to some dryer.

The invention also relates to a device for carrying out the method defined above.

When drying sawn timber, drying loads are often loaded on drying wagons. When the load is complete, the load and its wagon are transferred to the dryer. After drying, the wagons are emptied and the empty wagons are returned to the place of stripping of the dryer loads. This creates a closed cycle of the drying trolleys.

As is known, the sawn timber is dried in a dryer so that the load 52150 moves transversely. When using trolleys, there are difficulties in achieving the circulation of the drying trolleys.

One known way is to move the load out of the stripping elevator and to take the drying carriage s a in front of the drying room. The next empty carriage car is then brought back to the elevator along the fog track. However, this method is slow and time consuming.

Another known method is to bring the door to the empty side of the packaging plant on the side of the packaging plant, to move it sideways, by the bulk wagon behind the packaging plant to the packaging elevator and to work the Id from the drying trolley to the packaging elevator. However, the cost of this teenagers required defects are expensive and difficult to automate.

The object of the invention is to remedy the drawbacks which have arisen above and to provide a method and a device which are simple and easy to automate.

The Unlelta υα according to the invention is characterized in that the empty drying wagons are lifted from the first tracks to the roller track by a hoist, where the rollers meet the rail-like parts of the drying wagon from below and which rollers are raised with rollers directly to the support of the packaging elevator or to the rollers of another lifting device corresponding to said lifting device, which are at the level of the roller track and with which the empty drying carriage is lowered both to the packaging elevator and to the other tracks leading to the drying room.

The device according to the invention is in turn characterized in that the lifting device comprises a power device, such as a working cylinder and a frame structure connected to it, on the top of which the most suitably used rollers are mounted and that when transferred to the track.

The invention will be described in detail with reference to the figures of the accompanying drawing, in which the invention is in no way limited to the embodiment shown.

Fig. 1 shows the method in a schematic side view and Fig. 2 in the same schematic view from above.

Fig. 3 shows the drying trolley with a lifting device as seen from the direction of the tracks and Fig. 4 as seen from the same opposite direction.

Fig. 5 shows the timber package to be moved in the dry car as seen from the direction of the tracks and Fig. 6 from the same opposite direction.

The empty drying trolleys 1a with wheels 7 are brought from the drying room and the emptying place of the trolleys by a track 2a, at the end of which there is a lifting device 3a. When the empty drying carriage 1a has come on top of the lifting device 3a, the lifting device 3a is made to operate, whereby the rollers 5a meet the beams 4 arranged on the sides of the drying carriage 1a from below and the drying carriage 1a detaches from the rails 2a. The rollers 5a are preferably used as well as the rollers 5c in the same plane next to them, and thus the empty drying carriage 1a can be driven laterally by using the rollers 5 on the motor 12 via a chain 13. At the packaging plant 6 there are second tracks 2b, at the end of which there is a lifting device 3b similar to the end of the tracks 2a. The lifting device 3b also has rollers 5b »on which the empty drying trolley 1 rests. When the lifting device 3b is lowered from its upper position, the drying trolley moves to the tracks 2b and further to the packaging elevator 6, which is a structure known per se. When the timber package is completed, the drying carriage 1b with its timber packages moves to the drying room along the tracks 2b (the direction of transfer is shown in Figure 2 by arrows).

The lifting device 3 is formed by a frame structure 8 and a power device connected to it, such as a working cylinder 9. by means of which the drying carriage 1 rests on the rollers 5 during the lateral transfer, between the lifting devices 3a and 3b, rollers 5c are arranged, which are in the same horizontal plane as the rollers 5a and 5b in their upper position.

Figures 5 and 6 show, for the sake of clarity, a transverse timber package made on the drying trolley 1b, which consists of lumber layers 10 and a spacer 11.

Also within the scope of the invention is a method and device different from that shown in the figures, in which there is no second lifting device 3b at all, but an empty drying carriage 1 is led from the roller track 5a, 5c directly to the support of a packaging elevator 6 arranged at the end of the roller track 5c. In this application, when the sawn timber package has been made, the packing elevator 6 lowers the full drying trolley onto the tracks 2b to be transferred to the drying plant.

Claims (2)

4,52150 The method and device described above can be easily automated so that the different stages of the cycle of the drying carriages 1 and the operation of the devices automatically follow each other, e.g. under the control of the operation of the packaging elevator 6. A method for arranging an external rotation of drying kilns (1) moving in a transverse position in a lumber kiln, in which empty kiln wagons (1a) are introduced by first tracks (2a) onto a roller track (5) transverse to these tracks, along which empty kiln to the support or the tracks leading to it (2b), after which the drying carriage (1b) with its lumber packages (10,11) is moved along the second tracks (2h) to the drying room, characterized in that the empty drying trolleys (1a) are lifted from the first tracks (2a) ) with a lifting device (3a) in which the rollers (5a) meet the rail-like parts (4) of the drying carriage (1b) from below and which rollers (5a) are raised substantially to the same level as the other rollers (5c) of the adjacent roller track (5) and that the empty the drying trolley (1b) is moved by said rollers (5c) directly to the support of the packing elevator (6) or said lifting devices to the rollers (5b) of the second lifting device (3b) corresponding to (3a), which are at the level of the roller track (5) and by which the empty drying carriage (1b) is lowered both to the packing elevator (6) and to the second tracks (2b) leading to the drying room. Device for carrying out the method according to claim 1, characterized in that the lifting device comprises a power device, such as a working cylinder (9) and a frame structure (8) connected to it, on the upper part of which are preferably used (12,13) rollers (5a, 5b) , and that the drying trolley (1) has transverse, rail-like beams (4) which rest on the roller track (5) when the drying trolley (1) is transferred from the first track (2a) to the packing elevator (6) or to the second track (2b).
