Abstract

PURPOSE:To arrange and pile up timber on a board by utilizing the pressing force of the forward end of timer longitudinally transported on a transport path to a forward arm and sliding down the timber onto a board on the side of the transport path parallel thereto by a back arm. CONSTITUTION:When timber 3 is tranported in direcion of an arrow A, and the forward end of the timber is brought into contact with a forward arm 9, arms 9 and 10 start to rotate clockwise, until a roller 17 mounted at the forward end of the back arm 14 is brought into contact with the side of the timber. Further, when the timber 3 is transported in direction of the arrow A, the forward end of the timber 3 is brought into slidable contact with a sliding contact surface 10 of the forward arm 9 to be guided in direction of an arrow B, and simultaneously a forward roller 17 of the back arm 14 presses the timber 3 in direction of the arrow B. Thus, the timber 3 is dropped on a board to be kept parallel to a transport path 1 and the succeeding timbers are also arranged and piled on the board in the same manner.

Description

[Detailed Description of the Invention] The invention relates to an automatic sliding device for lumber, and more specifically, to a device for sliding wood vertically along a conveying path onto a predetermined platform provided on the side of the conveying path. be.

Conventionally, the work of sliding down timber has generally been carried out manually by workers, which has often caused the problem that the workers get injured by the work of sliding down the timber while transporting the timber.

Therefore, in order to save labor, an inclined plate was fixed in the middle of the wood transport path, and the tip of the vertically transported wood was placed on this inclined plate so that the wood would automatically slide down onto the board. Some things have been proposed.

However, in this case, the wood falls diagonally, resulting in the wood being piled up on the platform in a disorderly manner9, and the piled up wood must be rearranged later. did not become.

The present invention has been made in view of the conventional problems, and its purpose is to automatically move wood transported along a transport path.
- To provide an automatic wood sliding device that can slide down wood without using a separate driving force, and does not require re-arranging the wood later.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, which are exemplary embodiments of the present invention.

On the meat surface 2, reference numeral 1 denotes a conveyance path in which a large number of drum-shaped conveyance rollers 2 are arranged, and on this conveyance path, wood 3 cut to a certain length is conveyed in the direction of arrow A. A board stand 4 for loading lumber 3 is provided below the side of the transport path 1. On the side opposite to the board stand 4 of the transport path 1, there are two boards parallel to each other.
A blank rail 5 is laid down, and a slide plate 6 is movably provided on this rail 5. A fixing port 7 is provided on one side of the slide plate 6. By tightening this fixing bolt 7, the slide plate 6'? f
: Can be fixed at any position on the rail 5.

A support shaft 8 is erected on the upper surface of the slide plate 6.
A connecting portion 13 of an arm 9.14, which is an essential part of the support shaft 8, is rotatably supported on a horizontal plane. It has a sliding contact surface 1 (l) which is curved, and its back side is reinforced by a plate 11 on the MU side.One end of the plate 11 is fixed to the upper end of the support shaft 8. A spring 12, which is an example of a biasing means, is connected to the spring 12, and the spring 12 always biases the front arm 9 in the 21st counterclockwise direction.On the other hand, the rear arm 14 is The tip of the rear arm 14 is connected to the front arm 9 at a predetermined opening angle through the rear arm 13 (2), and this opening angle can be adjusted by rotating the turnbuckle 15. A pressing rod 1 having a loaf 17 in the part
The pressing rod 16 is inserted into the forward/backward movement mark 2, and the pressing rod 16 is fixed to the rear arm 14 by tightening the adjustment screw 18. Therefore, by fully adjusting the protruding length of this pressing rod 16, the total length of the rear arm 14 can be set to an appropriate length.

Here, the operation of the automatic sliding device consisting of the above configuration? This will be explained according to FIG.
14 is in a position rotated counterclockwise around the support shaft 8 by the biasing force of the 7-pull 12, and the rear arm 14 is retracted from the conveyance path 1 (Fig. 3a). 1, wood 3
is conveyed in the direction of arrow A and when its tip hits the front arm 9, the force causes both arms 9 and 14 to begin to rotate clockwise as a whole, and eventually the roller 17 at the tip of the rear arm 14 stays on the side of the wood 3 (Figure 3b). When the wood 3 is further transported in the direction indicated by the arrow, the tip of the wood 3 is guided in the direction perpendicular to the transport path 1 (in the direction of arrow B) while slidingly contacting the sliding surface 10 of the front arm 9, and at the same time, the rear arm 1
4's tip loaf 17 presses the wood 3 in the direction of arrow B (
Figure 30). In this way, the wood 3 falls onto the platform 4 while remaining parallel to the conveyance path 1, and the subsequent pieces of wood also fall in the same manner as described above, and are arranged and stacked on the platform 4.

If the wood 3r is to be slid down onto a board set at a different position, it is sufficient to loosen the 7 fixing bolts and move the slide plate 6 along the rail 5. In addition, when the wood 3 of different thickness is transported, the turnbuckle 15'i
All you have to do is rotate it to adjust the opening angle of both arms by 9 degrees and 140 degrees. Furthermore, when a short piece of wood is transported, the length of the rear arm 14 can be shortened by reducing the opening angle 2 of both arms 9° 14 and loosening 18 adjustment screws.

In the above-mentioned embodiment, the case where the sliding surface 1° of the front arm 9 is a curved surface is shown, but the same effect can be obtained even if it is an inclined surface. Also, a spring 12 whose both ends are connected to the support shaft 8 and the front arm 9 serves as a biasing means. r, but the present invention is not limited to this; for example, a torsion spring may be attached to the support shaft 8.

As is clear from the above explanation, fLtf! ,
Utilizing the force r exerted by the tip of the wood vertically fed on the conveyor path against the front arm, both arms are rotated together, so that the sliding surface of the front arm guides the tip of the wood in the stacking direction, and The rear arm presses the side of the wood so that it falls parallel to the woodworking platform.1 This allows the wood to slide down completely visually without any need for any additional driving force, and Since the wood is piled up on the board after being conditioned, there is no need to modify it later.
