A selecting monitor who operates a control panel monitors each log 39 passing on the chain belts 15 and 16 so as to determine, according to its kind, where the log 39 is to be allowed to fall.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wood sorting vehicle, and in particular, a self-propelled truck equipped with a sorting machine to enable sorting of logs at any location.

BACKGROUND ART Conventionally, there are various methods for sorting wood such as raw wood or product wood, such as tree type, straightness, original size, second size, and size. As a sorting machine used for these sorting, the wood is powered and transported to an extension stand of about 50 m, and while moving the visually sorted wood in the longitudinal direction of the extension stand,
Since the materials are dropped manually or by power onto one side of the extension table, a large space is required as a sorting place, and the efficiency of the sorting work is extremely low.

Therefore, the applicant provided a mobile wood sorting machine in which conveyance means such as a belt conveyor was mounted on a movable cart (Utility Application No. 15317/1983).

However, although this mobile wood sorter is mounted on a movable trolley, it has a configuration in which belt conveyors are arranged in tandem, which increases the width and overall length of the trolley, making it inconvenient to move. In addition, since it is necessary to at least be able to park the trolley and to have sufficient space for storing the sorted wood at the front, rear, and both sides of the trolley, there is still an inconvenience that a fairly large sorting area is required.

Therefore, in view of the above-mentioned circumstances, the present invention provides at least a large-sized

The upper end side is inclined to either the left or right, and the lumber 39 is floated from the roller conveyor 7 and falls onto the inclined table 8.8a. Preferably, the lumber 39 is assembled so that the vicinity of both ends can be levitated. Place it as. A control panel 45 is provided upright at the back of the driver's cab 2 together with the hood 46, and this control panel 45 controls the operation of each part.

Therefore, the operation of the present invention will be explained based on the above embodiment.

First, in order to move to the wood sorting area, as shown in Figs. It has been stored and is in good condition for driving. When they arrive at the wood sorting area, they operate the control panel 45 to first deploy the arm 12 of the side deployment platform 9 by driving the cylinder 24 to pull the ram 23 and move the arm 12 to the one side of the ramp. 8. Place and fix on top. Next, in order to expand the arm 14, the cylinder 26 is driven to pull the ram 25, and the leg 9 of the arm 14 is expanded.
Ground a. Thus, as shown in FIGS. 3 and 4, the side unfolding platform 9 extends to the side of the vehicle body to form a transport platform. On the other hand, in order to deploy the rear deployment table 27, the cylinder 3
5 to pull the ram 34 and pull down the column 29 toward the rear of the vehicle body 1. Further, the cylinder 37 is driven so that the frame body 31 is aligned with the column body 29, and the ram 36 is pushed out. In this way, as shown in FIGS. 7 and 8, the rear deployment platform 27 extends behind the vehicle body l and is placed and fixed on the ground.
The conveying devices 4, 4a are aligned on the same plane and in a straight line. Once the wood sorting work is prepared in this way,
Next, drive the hydraulic motor 17.20 to drive the chain belt 1.
5.16 toward the conveyance device 4, and the drive pulley 6 is rotated to rotate the roller chain 7. Further, the pulley 33 is rotated to rotate the roller conveyor 32 of the rear unfolding table 27.

Therefore, as shown in FIG. 9, the large amount of wood 39 stacked in the water storage area on the side expansion table 9 is loaded one by one onto the chain belt 16 using a crane or the like. The wood 39 is moved parallel to the vehicle body l by the chain belt 16, and the chain belt 1-1
5 and transported to the conveying device 4. Therefore, the sorting viewer who operates the control panel 45 must use the chain belt 15.
The wood 39 moving through the wood 16 is monitored and the place where the wood 39 falls is determined based on its type. That is, the first sorting location is the inclined table 8 facing the side development table 9. Therefore.

If you want to make the wood 39 fall onto the slope 8, when the wood 39 is placed on the roller conveyor 7, in order to operate the sorter 40, as shown in FIG. It is driven to project the ram 43 and move the plate body 42 upward. Since the upper end side of the plate body 42 is inclined to the right, the upper end side protrudes from the roller conveyor 7, floats the wood 39 from the roller conveyor 7, and causes the wood 39 to fall toward the slope 8 side. After the wood 39 has fallen toward the slope 8, the plate 42 is retracted below the roller conveyor 7 (see the phantom line in FIG. 5). The second and third sorting locations are inclined tables 8 formed within a range extending from the rear axle 3 to the tail end of the vehicle body, and are on both sides of the vehicle body l with the transport device 4 at the center. The conveying device 4 within this range is provided with a set of sorting machines 40 shown in FIG. 5 and a set of sorting machines 40a shown in FIG. 6, respectively. When the wood 39 moves to the tail of the car body 1, the sorter 40 is driven, and the wood 39 falls to the right side of the car body 1.
When a is driven, the wood 39 falls to the left side of the vehicle body l. The fourth and fifth sorting locations are inclined tables 8a and 8a on both left and right sides of the transport device 4a of the rear unfolding table 27. This conveying device 4a also has a sorting machine 40.4 as shown in FIGS. 5 and 6.
0a are provided as a set, and are driven in the same manner as described above, and the wood 39 that has been moved to the rear unfolding table 27 is selected to either the left or the right of the rear unfolding table 27 and falls down. 6th
The sorting location is behind the rear deployment table 27. That is,
The wood 39 that has been moved straight on the transport device 4.4a to the rear unfolding table 27 is moved straight ahead as it is and is thrown out to the rear of the rear unfolding table 27 at the approximate center.

In this way, after sorting the wood 39 to the first to sixth sorting locations, the cylinder 37 is driven to pull the ram 36 to the frame body 31.
Rotate so that it is perpendicular to the column 29.

At the same time, by driving the cylinder 35 to project the ram 34 and rotating the column 29 orthogonally to the vehicle body 1, the rear unfolding table 27 is folded and stored onto the vehicle body 1. Next, the cylinder 26 is driven to cause the ram 25 to protrude, and the arm 14 is rotated toward the arm 12 so as to approach it.
The cylinder 24 is driven to cause the ram 23 to protrude and the arm 12
is rotated about the shaft 18 so as to be perpendicular to the vehicle body 1,
The side unfolding stand 9 is folded and stored on the vehicle body i.

Note that if the wood 9 moving on the side unfolding table 9 is not transported parallel to the vehicle body but moves diagonally, the wood 3 will be transferred to the roller conveyor 7.
9 is not placed as a whole, causing trouble in conveyance, so it is better to provide a correction device to correct this. In this correction device, for example, disks that can move up and down in the orthogonal direction are disposed on both sides of the conveyance device 4, and one end of the wood 39 that has fallen from the side development table 9 to the roller conveyor 7 is placed on the roller conveyor 7. When the other end is outside the conveyor 4, the other end may be pushed up and moved onto the roller conveyor 7. Further, for example, similar to the sorting @40.40a, plates whose upper end sides are inclined to the left and right are provided to face both sides of the transport device 4 that are in contact with the side development table 9, so as to remove the wood 39 protruding from the transport device 4. It is also possible to selectively push up the end portion of the roller conveyor 7 and place it on the roller conveyor 7. The roller conveyor 7 may have one row in the center lower than the other two rows so that the timbers 39 can be transported regardless of their diameter.

According to the present invention described above, a wood sorting device is mounted on a large 1-rank self-propelled vehicle so that it can be folded and unfolded, and it is possible to sort up to six types of wood, making it compact. However, it is excellent in functionality, can be easily moved, does not require a large sorting area, and makes wood sorting work simple.
It can be done quickly and easily. In addition, the conveyance device is composed of three rows of roller conveyors, and the central row is set lower than the other two rows, so it can transport both small and large diameters. Furthermore, even if the wood is not placed parallel to the transport device but at an angle, it can be corrected and the wood can be transported smoothly, which improves the efficiency of sorting work.
