Method and apparatus for making a wood drying plant package Förfarande och anordning vid förflyttning av torkpaket av virke

The invention relates to a method for making a timber drying package using a stepwise or continuously descending elevator device, on which a desiccant package, preferably with intermediate rails, is made when the elevator descends stepwise or continuously as the elevator layer 5 accumulates timber layers with lower rails. in connection with both rails which bring empty timber wagons and rails which further carry timber-loaded drying wagons, in which method, when the elevator enters the down position, said timber-loaded wagon carries its wheels on the elevator rails, the latter being provided with a sufficiently large , that the loaded carriage moves mainly under the influence of gravity and moves away from the elevator to the departure rails, and in which method the empty carriage moves onto the elevator mainly by gravity and / or pushing.

The invention further relates to a device for carrying out the method according to the invention, comprising an elevator device consisting of vertical guides on which a carriage or the like moves by means of power devices a substantially vertical body part of the elevator 20, above which rails are fixed. in connection with the input rails and the output rails.

The method according to the invention is intended for use with sawmills, in which the ribbed lumber packages going to the dryer have to be moved from the ribbed elevator.

Dryer packages are often made by elevator on beams and finished packages are moved out of the elevator by a special conveyor or forklift.

Finnish patent applications 772501 and 8026G8 disclose: c— tin devices for moving timber packages away from the elevator. However, the conveyors become very expensive and the package breaks down easily during transport when it comes into contact with obstacles along the transport route. There is also a high risk of packages breaking down when transported by truck. In addition, the lower layers of the beam-stacked package are depressed and warped unusable, resulting in a large wastage of wood goods.

10 The lower layers of the package can be prevented from sagging if the package is loaded onto a trolley, which is then transferred by rail to the dryer. The inclination of the rails is usually such that gravity is sufficient to keep the wagons moving when they are first set in motion. However, from the elevator, the carriages do not start without an initial impulse. For this purpose, hydraulic pushers have been used to push the carriages out of the elevator. Because moving a full carriage requires a lot of force, the pusher becomes quite expensive.

The object of the present invention is to avoid the above-mentioned drawbacks 20 and to provide a method and an apparatus in which the drying trolley is moved from an elevator without expensive special pushing devices and essential external assistance.

In order to achieve the above and later objects, the method according to the invention is mainly characterized in that when the elevator is raised above the level of said rails, the car in the elevator is immediately arranged in a substantially horizontal position supported by its frame instead of being supported by its wheels.

The device according to the invention, in turn, is mainly characterized in that said rails are so-called quite arranged in the car body and that the elevator car is arranged so that when the elevator device is in the upper position the drying carriage will rest on the elevator frame 35 with the wheels of the drying carriage a certain distance from the elevator rails.

In the following, the invention will be described in detail with reference to the figures of the accompanying drawing, to which, however, the invention is not intended to be limited.

Figure 1 shows an elevator in an almost down position, to which an empty car has been introduced.

Figure 2 shows the elevator carriage in an elevated position.

Figure 3 shows an elevator in a down position from which a full timber trolley has just been moved away.

The timber packaging device shown in the figures comprises an elevator device which, in connection with the vertical guide 13, consists of an elevator car 16 moving on the carriage IA on an elevator car 15, which is moved in an up-and-down direction by a hydraulic cylinder 15 or other similar power device. Above the elevator device there are metering arms (not shown) known per se, which bring the timber layer by layer into the package P. The spaces between the layers of the package P are provided with spacers R to promote drying and cohesiveness of the package. The devices for importing and feeding the intermediate strips R are known per se and need not be described in this connection. The elevator body portion 16 descends as timber layers accumulate in the package P so that new timber layers can be introduced into the package P at substantially the same level. When the packet P is completed, it is transferred forward and a new packet is formed for the elevator.

The timber packages P are made on carriages 20 supported by an elevator, which move on their wheels 21 along rails 10a, 10b, 10c. The empty drying trolleys 20a are brought on the inlet rails 10a and stopped 30 in the waiting position shown in Figures 2 and 3 by a stop device 11 which is pivoted between open and closed positions by a cylinder 12. When the stop device 11 is opened, the trolley 20a can move for the elevator 16, as shown in Figure 1. The carriage 20 stops on the rails 10b of the elevator 16 when the end 23 of the carriage 20 collides with the protruding part 18 of the frame 17 of the elevator 35. In this case the elevator is not in the lowest position 66324 4, but its frame 17 is raised so that said end 23 of the carriage 20 catches to the protrusion 18 of the elevator frame 17, thereby preventing the empty carriage 20 from moving away from the elevator.

After the above steps, the elevator body 16 is lifted by a hydraulic cylinder 15, from which it begins to descend with the making of the package P. In this case, the carriage 20 remains entirely supported by its frame, e.g. its ends 23, on the elevator frame 17, as shown in Fig. 2. In this case, the wheels 21 'of the carriage 20' detach from the rails 10b at a certain distance Δ. This 10 is provided in such a way that the rails 10b are arranged to move to some extent in the vertical guides (not shown) in the up-and-down direction relative to the elevator frame 17 (so-called floating rails). A timber package P is collected on the carriage 20 'as described above and the elevator 16' descends stepwise or continuously until the sloping projections 22 at the ends of the floating rails 10b go into the corresponding recesses 19 at the edge of the elevator opening or at the ends of the rails 10a and 10c. supported by the projections 22. The elevator descends a little lower, whereby the elevator frame 17 is depressed so that it no longer touches the frame of the carriage 20, e.g. In this case, according to the invention, the inclination K of the rails 10b becomes e.g. : 120 so that it keeps the carriage 20 "in substantially smooth motion. - In Fig. 3, the height P of the complete timber package is denoted by Ht.

As can be seen from Figure 3, the next empty carriage 20a waits on the rails 10a. When the carriage 20 "has completely left the elevator 16, the elevator rises to the point where the projection 18 of its frame 17 stops the carriage from the elevator, after which this carriage is raised to the upper position as described above and a timber package P is collected.

As stated above, the carriage 20 "35 in the elevator support is in a horizontal position on the frame 17 of the elevator car 16 'and in a horizontal position with the elevator in the stacking position above the rails 10a and 10c. As the elevator descends when the package P enters the full 66624 - and on the recesses 19 at the ends of the output rails 10a, 10c so that the rails 10b will preferably extend about K = 1: 120 downwards in the direction of the output rails 10c so that the carriage 20 'moves on its own. less inclined downward in the conveying direction of the output rails 10c.

In the invention, the rails 10b attached to the body part 16 of the elevator are arranged in a floating manner so that the body part 16 and at least its frame 17 can be moved vertically with respect to the rails 10b. Firstly, this has the advantage that the frame 17 or its projection 18 makes the elevator slightly by raising the carriage 20 to the elevator as shown in Fig. 1. Secondly, in the stacking step, the carriage 20 'is brought onto the elevator body 16' or its frame 17, if necessary in a completely horizontal position, even if the rails 10b are considerably inclined in their lower position. A third advantage when using the floating rails 10b is that in the lower position they come to exactly the correct inclination on the groove-cantilever arrangement 19,22, even if there is a slight variation in the lower position of the elevator car 16. The floating fit of the rails 10b is also available with a variety of guide arrangements between the elevator car 16 and the rails, which allow vertical guided movement of the rails 10b relative to the carriage 16 within certain limits.

In the following, within the scope of the inventive idea defined by the claims, the various details of the invention may vary.
