Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for stacking and joining veneers for plywood, and more particularly to an apparatus capable of stacking and joining veneers fed upwardly with veneers fed downward.

Conventionally, when stacking and joining this type of plywood veneer, there is a supply section where the top and back boards are supplied in two pieces without gluing, and a stacking section where the glued middle boards are stacked and joined together. It was necessary to assign separate workers to each area. However, considering the amount of work involved, it can be easily carried out by a single operator if the supply section and the deposition section are adjacent to each other. Therefore, as shown in the first diagram, the automatic intermediate plate supply section B) the spreader C) the loading joint section D and the stacking section E are sequentially arranged toward the top plate and back plate combination supply section A arranged by the worker X. At the same time, it is desirable to transfer the combination F of the top plate and the back plate below the middle plate so that they join together at the loading joint D. In view of the above-mentioned circumstances, the present invention provides a plywood veneer stacking and joining device capable of stacking and joining a veneer supplied from above to a veneer below.

This will be explained below based on the illustrated embodiments. In Figure 2, combination 1 of the front plate and back plate is
The glued intermediate plate 3 fed to the lower conveyor row 2 is fed by a pinch roller 4 to a bridge 5 that can swing vertically.

Above the bridge 5, an endless belt 7 with a hanging stopper 6 is wound between the wheels Ba and 8b.
The rear end of the intermediate plate 3 supplied to the bridge 5 is pushed to the left in FIG.

A pair of guide rails 10 and 10' are arranged on the front and rear sides of this fork-shaped mounting table 9 in FIG. Two fork-shaped conveyance tables 11 and 11', which rotate around the gaps between the fork teeth of the placing table 9, are supported and guided by engaging with their guide rollers 1la and 11'a. A stopper 11b is provided on the rear end of the fork carrier 11 so that it protrudes upward from the gap between the fork teeth of the fork-like mounting table 9 when the fork carrier 11 travels on its upper circumferential track. In addition, the left and right ends of the guide rails 10 and 10' are
A moving guide 1 that moves up and down by a piston cylinder 12
3, and is adapted to be guided up and down by the movement guide 13 when rotating along the outer periphery of the wheels 14 and 15. Therefore, when the wheel 15 rotates around the outer circumference and moves upward, the top of the rear end part 11c of the fork-shaped conveyance table 11 pushes up the tip of the bridge 5, and prevents the supply of the middle plate 3. It is configured like this. on the other hand,
On the lower right side of the lower circumferential track of the fork-shaped conveyor platform 11 in FIG.
A plurality of conveyors 22 are arranged in a lattice shape for conveying the combination 1 of front and back plates that has been moved from the conveyor row 2 via a second bridge 21 that is provided to be swingable in the vertical direction.

This conveyor 22 consists of an endless belt wound between wheels 23 and 24, and its upper circumferential track is supported by a plate 25 to prevent bending during conveyance of the veneer. On the front side and the back side of the plurality of conveyors 22,
A pair of guide rails 26, 26 are arranged facing each other, and the guide roller 30a of the three fork-shaped conveyance platforms 30, 3 "30" attached to the endless chain 29 suspended between the wheels 27, 28 is It is designed to provide support and guidance by engaging with.

The fork conveyor 30 is configured such that each fork tooth 30a runs in a gap adjacent to the conveyor 22, and a stopper 30b standing vertically at the rear end of each fork tooth 30a is arranged above the fork conveyor 30. It is designed to protrude upward from the adjacent gap of the conveyor 22 when traveling on the circumferential track and from the gap between the fork teeth of the first fork-shaped conveyance platform 11 when traveling on the lower circumferential track. The left and right ends of the guide rail 26 in FIG. When the fork-shaped conveyance platform 30 attached to the endless belt 29 rotates along the outer periphery of the wheels 27 and 28, it is supported and guided by the vertical movement of the moving kite 32. Near the starting position of the lower orbit of the fork-shaped conveyor platform 30. A stopper row 33 is vertically protruded with a gap between each fork tooth 30a, and near the start position of the upper circumferential orbit, a bridge 21 is installed at the top of the rear end part 30c of the fork-shaped conveyance platform 30. It is configured to be lifted upward to prevent movement of the veneer from the conveyor row 2.

Note that the driving force supplied from a driving source (not shown) is the fourth
As shown in the figure, the rotational speed is transmitted to each wheel via transmission gears 34, 35, etc., and by appropriately setting the rotation ratio between adjacent wheels, a correlated operation between each mechanical part is obtained.

In the loading and joining device configured in this way, the glued middle plate 3 is placed on the fork-shaped mounting table 9 via the bridge 5, and at the same time, the fork-shaped conveyance table 11 rotates around the outer circumference of the wheel 15 to move the upper circumference. After starting to travel on the track, the intermediate plate 3 is pushed to the left in FIG. Start running on the orbit.

On the other hand, the combination 1 of front and back plates on the conveyor row 2 is transferred onto the conveyor 22 via the second bridge 21, and immediately after that, the second fork-shaped conveyor 30 rotates around the outer periphery of the wheel 21. and start traveling on the upper orbit. A stopper 30 is installed vertically at the rear end of the high-speed fork-shaped conveyance platform 30.
First, by b, the combined veneer 1 on the conveyor 22 is transferred onto the fork-shaped conveyance platform 30, and then the intermediate veneer 3 on the fork-shaped conveyance platform 11, which is running on the lower circumferential track to the right in FIG. 2, is transferred. be placed on top of it. After this, the laminated plywood on the fork-shaped conveyance table 30, which has been guided by the movement guide 32 and entered the lower circumferential orbit, is prevented from moving to the right in FIG. 2 by the stopper 33, and the fork-shaped conveyance table When it passes the stopper 33 position of No. 30, it is dropped and placed on the stacking table below.At this time, another fork-shaped conveyance table 3' has finished loading the veneer, and yet another fork-shaped conveyance table 3' has finished loading the veneer. While one of the first fork-shaped conveyance tables 11, 1' is traveling on the lower orbit, the other one starts transferring another intermediate plate 3 on the fork-shaped mounting table 9. In this way, the stacking and joining of the veneers that are sequentially supplied to the conveyor row 2 and the first bridge 5 is performed continuously. The speed is lower than that of the fork-shaped conveyor 30, or the speed is intermittently switched between low and high speeds.As described above, according to the plywood veneer loading and joining apparatus according to the present invention, the plywood veneer is supplied from above. This system is capable of continuously loading and joining the lower veneer and the lower veneer, and by feeding the lower veneer in a direction that crosses the upper veneer transfer line, the veneer combination supply unit and It becomes possible to make the stacked parts of the plywood boards adjacent to each other after stacking and joining.
