As shown in the figure, the main parts of the present invention are a supply conveyor device l,
Sorting consists of a conveyor device 2, a movable floor type collection shelf device 3, and a packing device 4.

The supply conveyor device 1 carries sawn timber products 5 in a horizontal position...
This conveys the lumber horizontally without changing its posture. Specifically, it has a horizontal conveyor 7 with two conveyor chains 6 and 6 arranged horizontally to support the lumber 5 in the cross-over position from below. .

In the sorting process, the conveyor device 2 receives the lumber 5 transported by the supply conveyor device 1 one by one by the vertical conveyor device 8 and sends it out to the outside by the extrusion device 9 at an appropriate fixed height position. It is structured as follows. That is, the vertical conveyor device 8 is disposed close to the conveyance end of the supply conveyor device 1. The device 8 consists of a pair of laterally opposed vertical conveyors 10.10, each vertical conveyor 1O11O having a symmetrical configuration.

The vertical conveyor 10 is as shown in FIGS. 3(a) and 3(b).
A conveyor chain 13 in which pins 12 on one side of an inverted T-shaped cylindrical support piece 11 are pivoted at regular intervals is connected to four guide wheels 14.
A rotating mechanism 16 has a configuration in which the hook rotates around ... and one of the guide wheels 14 is interlocked and connected to the motor 15.
The other pin 18 of the cylindrical body supporting piece 11 is supported by the conveyor chain 17. Another orbiting mechanism 19, which is substantially similar to the orbiting mechanism 16, is formed so that the pieces 11 are pivoted at a fixed interval at a certain angle, and the upper edges of the main bodies 20, 21 of each orbiting mechanism 16.19 are formed. The guide side 22.23 is gradually raised in the circumferential direction, and the relative positions of the guide side 22.23 and the conveyor chain 13.17 are set in a constant relationship. Furthermore, extrusion devices 9 are arranged vertically at regular intervals between the pair of vertical conveyors 1o, 1°, and each extrusion device 9 has two hydraulic or pneumatic cylinders 24, 24. It is arranged horizontally.

The movable floor type collection shelf device 3 sorts the lumber products 5 sent out by the conveyor device 2 at an appropriate fixed height of a collection shelf 26 consisting of a plurality of stages each having a conveyor floor 25. While being accommodated on the conveyor floor 25, necessary sawn lumber products 5 are sent out to the outside at any time based on appropriate driving operations. Specifically, the lumber product 5 is constructed as follows. That is, the vertical columns 27 and beams 28 are used as a frame structure to form a collection shelf 26 consisting of multiple stages, and each stage is equipped with two conveyor chains for horizontally placing the lumber products 5. 29 and a conveyor floor 25 with 29 installed in parallel. Each conveyor chain 29.29 is configured to be driven intermittently by a motor 30.30 so that the extrusion device 9 can convey the sawn products 5 forward by the same length in accordance with the stroke of extruding the sawn products 5. Moreover, on the other hand, the collected sawn timber products 5 can be transported rearward by an appropriate distance even by manual driving operation.

The packing device 4 receives the lumber products 5 sent out by the movable floor collection shelf device 3 onto a conveyor table 32 installed on a vertically movable table 31, and moves up and down on the vertically movable table 31. It is placed on the movable stationary table 33 in an easy-to-handle manner and is constructed as follows. That is, the vertically movable table 31 can be moved vertically by a suitable telescopic drive mechanism 34, 34 so that the upper surface of the conveyor table 32 can be at the same height as any conveyor floor 25 of the collection shelf 26. The telescopic drive mechanism 34 may be a piston-cylinder mechanism, a pantograph mechanism, or the like. The two-strand conveyor chain 35.35 on the conveyor table 32 is driven by a motor (not shown), and is displaced intermittently or continuously in synchronization with the conveyor chain 29.29 on the conveyor floor 25. It is a thing. Further, a fork conveying device 36 is provided slightly below the upper surface of the conveyor chain 35.35, and two forks 37.37 forming a part of the device 36 are mounted on the conveyor chain 35.35. By scooping up some of the lumber products 5... sent out in a sideways position from below, moving them forward, and lowering them, the sawn lumber products 5... are brought to almost the same height as the conveyor chain 35.35. It operates so that it is placed on the upper surface of the movable stationary table 33, which is located at the same time, and then moves backward and returns to its original position. In addition, when the forks 37, 37 move backward from the movable stationary table 33, the transported sawn products 5 are locked so that they do not return to the rear together with the forks 37, 37. Therefore, a locking protrusion (not shown) is configured to protrude and descend at the frontmost end position of the movable stationary table 33 in synchronization with the operation of the fork 37, 37. In addition, the movable stationary table 33 is provided with forks 37, 37 in order to realize stacking of sawn timber products 5... by forks 37, 37.
．． In synchronization with the operation of 37, the vertically movable table 31 is moved up and down in stages by appropriate telescopic drive mechanisms 38 and 38. The movable stationary table 33 is configured to be able to move up and down independently.

Next, the operation of the apparatus of this embodiment during sorting and collection will be explained. The supply conveyor device 1 sorts the lumber 5 placed horizontally on the conveyor chain 6.6 to the conveyor device 2.
Transport towards. The sawn lumber 5 that has reached the end of conveyance of the apparatus (1) is placed on one side of the thin support piece 11 by a conveyor chain 6.
6 is forcibly moved and pressed against the rear side of the main body 16.19 forming a part of each vertical conveyor 10.10, so that it assumes a constant position in the transverse direction. In this connection, the conveyor chain 13 of each orbiting mechanism 10, 10
．． 17 rotates in a fixed direction f by l pitch of the thin body supporting piece 11, and this time, the sawn product 5 is placed on the next thin body supporting piece 11 in a constant posture as described above. By repeating this operation, the sawn products 5 on the conveyor chain 6.6
... are carried out one by one by the thin body supporting piece 11.

Thereafter, the thin support piece 11 sequentially transports the placed sawn product 5 to the upper edge of the main body 20.21 of each rotating mechanism 16.19. Now, one sawn product 5 is placed on the guide side 2 of each vertical conveyor 10, 10, as shown at 5a in FIG.
2.23, the lower surface of the sawn product 5 gradually approaches the guide edge 22.23 as the thin support piece 11 moves, and finally reaches the guide edge 22, as shown at 5b in FIG. ．．
It will be in a state where it is placed at a certain position of 23. Thus guide edge 2
2. The sawn lumber 5 placed on the 23 remains in that state until the next back support piece 11 moves, and when the next back support piece 11 reaches a certain position, its protrusion The front surface of the section comes into contact with the rear surface of the lumber product 5 as shown by the solid line in FIG. 4, and is then pressed and displaced in the circumferential direction as the back support piece 11 moves. When this back body support piece 11 is circumferentially displaced to a certain position, the sawn lumber 5 that has been pressed and displaced by this back body support piece 11 until then is moved to the upper edge of the main body 16, 19 on each vertical conveyor 0, 10. The lumber product 5 is lowered by its own weight along the back support piece 11, and is finally placed on the other side of the back support piece 11 as shown at 50 in FIG.
It will descend while being placed on 1. In this way, the back support piece 11 that conveys the lumber product 5 will eventually reach the same height as the conveyor floor 25 of the movable floor type collection shelf device 3 selected in advance by the operation operation, and will be at the same height. When this is reached, the pressing device 9 located at approximately the same height as the conveyor floor 25 is activated, and the lumber 5 placed on the back support piece 11 is pushed out onto the conveyor floor 25 selected in advance. It is possible.

On the other hand, in the movable floor type collection shelf device 3, the motor 30.30 of the selected conveyor floor 25 operates in synchronization with the pushing device 9, and the conveyor chain 29.29 operates in synchronization with the pushing device 9.
The lumber 5 is moved forward by the width of the extruded lumber 5. As a result, the lumber products 5 . . . that are successively conveyed by the back support pieces 11 .

Here, if the long sawn timber products 5 are collected on the uppermost conveyor floor 25, even if the sawn timber products 5 are stacked on the vertical pillars 27 that constitute the movable floor type collection shelf device 3. It becomes possible to collect even items that are longer than the mutual distance in the lateral direction. However, even with the apparatus of this embodiment, the sawn timber products 5 to be collected on the conveyor floor 25 other than the top stage are placed on the vertical pillars 27...
It is unavoidable that the maximum length is restricted by the lateral mutual spacing of .

Furthermore, the operation of the device of this embodiment at the time of shipment will be explained. Operation is performed to move the conveyor floor 25 of a predetermined stage according to the specifications and quantity of the lumber products 5 to be shipped. This causes the conveyor table 32 to move up and down, and the conveyor chains 35,35 to be at the same height as the predetermined conveyor floor 25. In this connection, a predetermined motor 30.
30 is activated and the conveyor chain 29.29 is moved by a certain distance, and the conveyor chain 35.35 of the conveyor table 32 is also moved in the same manner to remove the sawn products 5 and 5 on the selected conveyor floor 25. . . are taken out in a certain amount onto the conveyor table 32.

After that, the conveyor table 32 moves to the reference position and stops, and then the forks 37.
37 places the sawn product 5 on the conveyor chain 35.35 onto the movable stationary table 33.

If the quantity of the placed lumber products 5 is less than the quantity to be shipped, the conveyor table 32 operates again to move the lumber products 5 on the selected conveyor floor 25 in the same manner as described above. It is placed on the movable fixed table 33.

At this point, the movable stationary table 33 is in a state in which it has been displaced downward by a certain distance with respect to the conveyor table 32, and the fork 37.37 is placed on top of the previously placed sawn product 5... ...is stacked in layers. Thereafter, operations similar to those described above are repeated until a predetermined shipping amount of the lumber products 5... is reached.

The lumber products 5 that have reached a predetermined shipping amount are then packaged if necessary and then transported to another location using a forklift, trunk, or the like.

In the above embodiments, each device was described as being automatically operated by sequence control, but each device may be operated manually.

(Effects of the Invention) As described above, according to the present invention, it is possible to sort, store, and pack sawn timber products 5 simply by operating the machine, and the labor involved in the work is significantly reduced. This greatly improves work efficiency.
