DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in the drawings. 1 and 2 are overall views of an embodiment of the present invention, in which 1 is a frame, 2 is an upper rail horizontally provided on the upper portion, and 3 is a lower rail horizontally provided on the lower portion. . A large number of wicket bars 4 are slidably supported on these rails 2 and 3. Soshi
The upper rail 2 is a wicket bar on which the work is placed.
4 is a forward path for moving from the loading position side to the unloading position side,
The lower rail 3 takes out the work and empty
The tover 4 is moved in the opposite direction to that of the upper rail 3.
It is a return trip. The wicket bar 4 has a plurality of arms 4a fixed in parallel to a shaft 5 as shown in FIG. 3, and has a structure in which a flat work W can be placed and transported on the upper surface thereof.

The wicket bar 4 is provided with two rollers 6 at both ends of a shaft 5, and as shown in FIG.
By supporting the lower surfaces of these rollers 6 on the rails 2 and 3, the arms 4a can be freely slid on the rails 2 and 3 while keeping the arm 4a at a fixed inclination angle.

Below the rails 2 and 3 of the above-mentioned reciprocating path ,
Strings 7 and 8 for driving a wicket bar are arranged in parallel with the rails 2 and 3, respectively. The string-like members 7 and 8 are made of a normal endless chain conveyor or endless belt, and the upper surfaces thereof are rails 2 and 3 as shown in FIG.
By contacting the lower surface of the roller 6 of the wicket bar 4 supported by the wicket bar 4, the wicket bar 4 can be moved in the direction of the arrow in FIG. 1 by frictional force. And these going
A stopper 9 is provided at the end of the rail 2 on the side of the work unloading position, at the end of the rail 3 on the return path at the side of the work loading position.
Is provided with a stopper 10, but at least
The stopper 10 is used to adjust the timing of the work loading operation.
In order to control the movement of the empty wicket bar
It is provided to be able to. Also, this stopper 9,
When the advancement of the wicket bar 4 is stopped by 10, only the cords 7 and 8 can be made to idle.

At both ends of the rails 2 and 3, there are provided blocks 11 and 12 for holding the wicket bar 4 sent out from the rails 2 and 3, and up and down mechanisms 13 and 14, respectively. The blocks 11 and 12 have the same cross section as the rails 2 and 3, and can directly receive the roller 6 of the wicket bar 4 sent out from the rails 2 and 3. The elevating mechanisms 13 and 14 are, for example, slide actuators, and can support the blocks 11 and 12 via brackets as shown in FIG. A rotation mechanism 15 such as a rotary actuator is provided on the block 11 at the end of the upper rail 2, and the arm 4 a of the wicket bar 4 is tilted horizontally by rotating the block 11 as shown in FIG. Is available.

In addition, moving mechanisms 16, 17, 18 and 19 for moving the wicket bar 4 between the rails 2 and 3 and the blocks 11 and 12 are horizontally provided at both ends of the rails 2 and 3. I have. Each of these moving mechanisms 16, 17, 18, and 19 has a feed claw 20, and the wicket bar 4 is connected to the rail 2
To the block 11, from the block 11 to the rail 3, from the rail 3 to the block 12, and from the block 12 to the rail 2.

[0011]

In order to use the wicket-type conveyor of the present invention configured as described above for supplying a workpiece to the plating apparatus described above , first, the wicket-type conveyor is supported by the block 12 at the workpiece loading position at the rear end of the forward rail 2. An operator places a flat work W on the arm 4 a of the wicket bar 4. Then, the operator operates the switch to activate the moving mechanism 19 to feed the wicket bar 4 onto the rail 2.
The wicket bar 4 sent on the rail 2 is a string-like body 7.
As a result, the workpiece is advanced in the direction of the work unloading position, and stops at a position where it hits the stopper 9 at the tip end. Next, the worker lowers the empty block 12 by the lifting mechanism 14,
The next wicket bar 4 is received from the lower return rail 3 and is raised again by the elevating mechanism 14 so that the flat work W is placed thereon. By repeating the above operation, a large number of wicket bars 4 on which the work W is loaded and placed can be accumulated on the outward rail 2 as shown in FIG.

Next , when the operation of the plating apparatus is started, the stopper 9 is removed, and the moving mechanism 16 is operated, the wicket bar 4 at the tip of the rail 2 is placed on the block 11. At this time, the block 11 is rotated clockwise in the drawing by the rotation mechanism 15 to make the work W horizontal. Robot not shown in this state to adsorb the workpiece W, and out transportable to the plating apparatus. This operation is performed once every three minutes, and one wicket bar 4 is moved from the rail 2 to the block 11 one by one according to the timing. The wicket bar 4 from which the work W has been taken out and emptied is lowered by the elevating mechanism 13 and transferred to the return rail 3 by the moving mechanism 17. The wicket bar 4 thus emptied in this way is sequentially transferred onto the rail 3 and
The workpiece is moved to the loading position by the
Is suspended on the return rail 3 in the same manner as described above by the action of the stopper 10 that is operating . For this reason, for example, when ten wicket bars 4 can be accumulated , 30 minutes which is the operation time of the plating apparatus is :
Work loading operation may be interrupted, and unmanned operation is possible.

When the number of wicket bars 4 on the outgoing rail 2 decreases and a number of empty wicket bars 4 are accumulated on the returning rail 3, the operator moves the block 12 up and down the lifting mechanism 14 in the same manner as described above. while up and down by, strike
Release the action of the upper 10 and empty from the rail 3 on the outward path.
The wicket bars 4 are raised one by one, and the work W is loaded. Assuming that the charging operation takes 0.5 minutes each, the operation of accumulating 10 wicket bars 4 on the outgoing rail 2 is completed in 5 minutes, and the operation of the plating apparatus is completed.
The remaining 25 minutes of the 30 minutes a rolling time it is possible to perform other tasks.

[0014]

As described above, unlike the conventional wicket type conveyor, the wicket type conveyor according to the present invention allows a large number of wicket bars to be alternately accumulated on the outward and return rails. Even when the operation interval of the work does not coincide with the work loading time of the work on the wicket bar by the worker, there is an advantage that the worker does not need to take useless waiting time and the work can be rationalized. Therefore, the present invention has a very large practical value as a wicket type conveyor which has solved the conventional problems.
