Wood delivery device 1 is a filling space of the storage space 11 is formed, and that the filling space can be specified limited by the stop element 7. In associated methods, it can be provided, in particular, that a multiplicity of pieces of wood 2 are introduced into the first area 4 during an initial filling operation, and held in the first area 4 by the stop element 7, until a shock substantially stable and up to a desired storage height is formed 13 has formed from pieces of wood 2, and that at one end of the Erstbefüllvorganges the stop element 7 the shock 13 of pieces of wood 2 releases. The timber conveying device 1 can therefore be particularly preferably a part of a store 10, particularly preferably a temporary store, wherein the timber conveying device 1 of individual pieces of wood 2 forms a stable multi-layered pile 13 of pieces of wood. The storage space 11 is that space of a storage 10 which is provided for multi-layer storage of the pieces of wood 2. The filling space is a space in the storage space 11, which is provided for receiving the pieces of wood in a Anfangsbefüllvorgang. The filling space can in particular be a subset of the first area 4

The first area 4 of the timber conveying device 1 may in particular only make up a part of the storage space 11, in particular make up less than 20% of the storage space 11.

In particular, it may be provided that a conveying device 12 is arranged on an underside of the storage space 11. The conveyor device 12 can be designed in particular as a continuous conveyor, particularly preferably chain conveyor. The conveying device 12 may in particular be a transverse conveyor. Furthermore, the conveying device 12 may preferably have extensions which prevent the lowermost layer of pieces of wood in the joint 13 from uncontrolled rolling. By the Conveying device 12 can be achieved that the storage space 1 1 can be reliably filled and emptied.

Furthermore, it can be provided that the conveying device 12 extends substantially over an entire longitudinal extent of the memory 4.

Particularly preferably, it can be provided that in a first end 19 of the storage space 11 of the charging space is formed, and that the charging space can be limited specifiable by the stop member 7 to prevent a leaving the pieces of wood 2 from the Anfüllraum predeterminable. The first end 19 of the

Memory space 11 may in this case correspond in particular to the beginning 5 of the first area 4. It can be provided that during the

Erstbefüllvorganges a memory 10 of the shock 13 of pieces of wood 2 is held by the stop member until a substantially stable and formed to a desired storage height first end face 18 of the shock 13 from

Wood pieces 2 has formed, and that at one end of the Erstbefüllvorganges the stop element 7 is moved from the storage space 9. By the

Stop element 7 can therefore be effected so that the shock 13 is first built up at least to its desired storage height, before the first end face 18 is moved away by the conveying device 10 from the first end 19 of the storage space 11. As a result, a particularly steep first end side 18

be formed, whereby the storage height at a filled memory 10 over the entire length can be the same, whereby the stored amount of pieces of wood 2 is large.

In particular, the stop element 7 can retain the pieces of wood 2 until the first end face 18 has an inherently stable slope angle. The inherently stable slope angle can be in particular between 60 ° and 45 °.

Furthermore, it can be provided that one of the storage 10 has a storage volume of at least 10 m ³ , in particular at least 20 m ³ , particularly preferably at least 50 m ³ , of pieces of wood 2, in particular round wood.

In particular, it can be provided that the storage space 11 of the store 10 has a desired storage height, which set storage height is at least 1 m high.

Particularly preferably, it can be provided that the timber conveying device 1 is switchable between the first operating mode and the second operating mode.

If storage of the pieces of wood 2 is not necessary, the

Wood conveying device 1 from the second mode to the first

Operating mode can be switched again, causing the pieces of wood 2 the

Height difference of the target storage height can bridge quickly and safely.

Furthermore, it can be provided that the conveying device 12 has an increase of 1% to 10% with increasing distance from the first end 19 of the storage space 11. This can reduce the likelihood that individual pieces of wood 2 will roll off the bump 13.

Particularly preferably, it can be provided that the pieces of wood 2 in the

Storage space 11 of the memory 10 as a shock 13 are stored in multiple layers, and that a first end 19 of the storage space 11 facing away from the first end face 19 of the pile 13 of pieces of wood 2 through the arranged at the bottom of the storage space 11 conveyor 12 during filling of the memory 10 of the the first end 19 of the storage space 11 is moved away, wherein the shock 3 on one of the first end face 19 facing away from the second end face 20 is filled with pieces of wood 2. The shock 13 of pieces of wood 2 is in other words not constructed from bottom to top, but built at the first end 19 of the storage space 11 and then transported in the direction of one, the first end 19 opposite the second end 21 of the storage space 1, wherein the shock 13th is further filled at the first end 19 of the storage space 11. This can be a high degree of filling of the memory 10 can be achieved.

In particular, it can be provided that the filling space has a variable volume, and that the stop element 7 is formed by retaining the pieces of wood 2 to keep an upper edge of a joint 13 of pieces of wood 2 in the filling space on a predetermined desired height range. In the case of methods, it may be provided that, during the initial filling operation, a movement of the stop element 7 causes an upper edge of the joint 13 on pieces of wood 2 to be predetermined

Target height range is maintained. This can prevent that in a still very empty memory 10, the introduced into the memory 10 pieces of wood 2 fall uncontrollably down, and thereby be damaged or querlegen. The predeterminable variable volume of the charging chamber can be achieved in particular by means of at least one rotary arm 8, since the volume of the charging chamber can be predeterminably increased by rotating the rotary arm 8 in the first region 4.

The desired height range may further be greater than the desired storage height of the memory 10. The predefinable desired height range can be specified in particular by the control of the stop element and / or the conveyor device 12.

Particularly preferably, it can be provided that the guide 3 has a ramp 22 in the first region 4, in particular adjacent to the beginning 5 of the first region 4. The ramp 22 may in particular lead from the beginning 5 of the first area 4 to a low point of the first area 4. The low point, according to an embodiment not shown, also with the end 5 of the first

Area 4 coincide. According to the preferred embodiments, the low point between the beginning 5 and the end 6 of the first area 4

be arranged.

Here, the ramp 22 may in particular at least partially follow the course of an outermost point of the at least one rotary arm 9 such that the minimum distance between the ramp 22 and the at least one rotary arm 9 is smaller than a diameter of the piece of wood. 2

Preferably, at least a portion of the ramp 22 may be substantially as Cylinder surface is formed, which cylinder surface can be in particular coaxial with the axis of rotation 8 of the rotary arm 9, and substantially the same radius as the rotary arm 9 has. Such a ramp 22 is shown in FIGS. 2 to 5.

According to a preferred embodiment, not shown, it can be provided that the distance between the outermost point of the rotary arm 9 and the ramp 22 is increased by the shape of the ramp 22 during a downward movement of the rotary arm 9. Thereby, a steeper ramp 22 can be achieved, in which the shock 3 becomes more stable and less slips through the ramp 22.

Furthermore, the ramp 22 may have recesses through which recesses of the at least one rotary arm 9 can pass. Such a ramp 22 is shown in FIG.

Furthermore, it can be provided that the conveying device 12 is part of the guide in the first region 4.

In Figures 2 to 5, the operation of the rotary arm 9 is exemplified in the second mode.

In Fig. 3 it is shown that the rotary arm 9 is rotatable by 360 ° about the axis of rotation 8, wherein depending on the type of actuation of the rotary arm 9 and a smaller

Pivoting range is possible. In Fig. 4, the rotary arm 9 is shown in an initial position, in which it is substantially horizontal. As the filling area begins to fill, the rotating arm 9 predeterminably moves downwardly to adjust the volume of the filling space to the volume of wood pieces 2 therein. In Fig. 5, a state of the rotary arm 9 is shown, in which the volume of the Anfüllraumes constitutes substantially 50% of a maximum volume. In this case, this maximum volume can correspond to the volume of the first region 4. The rotary arm 9 continues to rotate during further filling until the first end face 18 has the predetermined slope angle. Then, the rotary arm 9 is moved from the storage space 11 to a release position and the shock 13 is released. The release position of the rotary arm 9 is shown in Fig. 2. In an emptying process in this case the shock 13 can be moved away under the stop element 7, wherein the filling space is emptied.

In this case, it can be provided, in particular, that when the filling space is empty, the stop element 7 is brought back into the starting position. Since the emptying of the memory 10 is usually faster than the filling can thereby be started before a final emptying of the memory 10 with a new filling process, the stop element 7 the just-emptying shock 13 and a newly replenished shock 13 reliably from each other separates. As a result, the method can be particularly effective and space-saving, wherein in particular the newly refilled bump 13 is reliably separated from the shock 13 which has just been emptied.

A filling space with a variable volume can alternatively be achieved in that the stop element 7 is movable in the conveying direction to the second end 21 of the storage space 11. In this case, the storage space 11 would correspond to the first area 4.

Alternatively, it can further be provided that the filling space has a constant volume. For example, in this case, the stop element 7 form a barrier limiting the first region 4, which barrier is removed to release the impact 13.

Furthermore, a wood sorting plant 14 may be provided with a first longitudinal conveyor 15 for the separated transport of the pieces of wood 2 in the longitudinal direction, along the first longitudinal conveyor 15 a plurality of stationary storage 10 are arranged for multi-layer storage of the pieces of wood 2, that the pieces of wood 2 predetermined by means of a sorting device from the first longitudinal conveyor 15 are deflectable into the memory 10, and that each of the memory 10 a

Storage volume for pieces of wood 2 can be easily provided. This results in the advantage that the pieces of wood 2 can be sorted safely, space-saving and with little effort. By the memory 10, which in turn can feed a second longitudinal conveyor 17, can be dispensed with the use of loaders 23, and the sorting process essentially done with a high degree of automation, whereby the logistics can be simplified. Here, a sorting can be done essentially exclusively with continuous conveyors, whereby the sorting process can be accelerated, and the risk of accidents can be banned by discontinuous conveyor. Furthermore, fewer personnel are required, which makes the sorting process more efficient.

Furthermore, the space requirement can be kept low because no

Maneuvering surfaces for the loader 23 are more necessary. Due to the stationary and multi-layer memory 10, a high storage density of pieces of wood 2 per area can be achieved, whereby the space requirement can be kept low.

The longitudinal conveyor 15,17 is a conveyor which transports the piece of wood 2 along its longitudinal direction. Here, the piece of wood 2 are transported separated, so that they can be sorted on the first longitudinal conveyor 15.

In the sawmill 25, the pieces of wood 2 can then be processed, for example, to boards.

Particularly preferably, it can be provided that a transport of the pieces of wood 2 from the first longitudinal conveyor 15 to the second longitudinal conveyor 17 via the memory 10 takes place only by means of continuous conveyor. A continuous conveyor is a conveyor which continuously conveys a conveyed material, in this case the piece of wood 2, for example chain conveyors, conveyor belts or roller conveyors. The predefinable SoUhöhenbereich may in particular less than 0.5 m, preferably less than 0.3 m, below a conveying height of the piece of wood 2 on the first longitudinal conveyor 15 lie.

These can then be brought to polter by loader 23, from which they are then removed conventionally. As a result, it can be prevented that the storages 10 have to pick up pieces of wood 2 which are only rarely or not at all processed by the sawing plant 25.

Preferably, it may further be provided that the pieces of wood 2 are divided into different sorting classes and the sorting classes are assigned to predeterminable groups of stores 10, and that the pieces of wood 2 of the

Sorting device according to the sorting class of the first longitudinal conveyor 15 are deflected in the, associated with this sorting class memory 10. In this case, a plurality of memories 10 are assigned to a sorting class. As a result, when emptying the memory 10 at least one memory 10 may still be provided per group, which can continue to be filled when the other memory 10 of the group is emptied.

In particular, it can be provided that in an emptying process a plurality of storages 10 of a group assigned to a sorting class are emptied. The memories 10 of a group can be emptied parallel to each other or one after the other. In particular, it can be provided that all memories 10 are emptied except for one. This allows the sawing system 25 with large batches

Wood pieces 2 are supplied per sorting class, whereby the changeover times of the sawing system 25 can be kept low when changing the sorting class.
