The shafts 1a are constructed so as to fit into the intermediate positions of the adjacent shafts 8 one after another.

The operation of the device configured as described above will be described.

First, from the chute 42 to the roller conveyor 2 of the supply device 20
When the workpieces 3 are fed onto the surface of the workpieces 1, each workpiece 3 is transported by free rollers 26, 26, which can rotate on their own axis. Due to the rotation of the free rollers 26 due to gravity, the particles are dispersed in the front and rear directions as well as in the left and right directions, resulting in a flat state, and the transfer member 28 of the vibrating conveyor 22
Move to the top of the screen.

Then, the objects 3 to be processed fit into the respective grooves 27 on the upper surface of the transfer member 28 and are arranged in a plurality of rows.

Of the objects to be processed in each groove 27, the ones at the forefront sequentially enter between the push-up bodies 35 of the input mechanism 23, and the objects rotated together with the rotating shaft 34 pass through the lower part of the sorting conveyor 2. Each screening hole 10a, 10 of the laminate 4 of
b, 10 C... and transported forward together with the laminate 4.

At this time, the abutting body 4d is moved forward while being held in the hanging position with its forward rotation being restricted by the stopper 11.

The stacked body 4 carrying the workpiece 3 reaches the first section X1 of the transfer route X, passes over the first guide rod 6a, and moves on the inclined guide 16a, but at this time, 4a rotates downward along the inclined guide 16a at a speed slower than the rotation speed due to its own natural fall, so the workpiece 3 extracted forward from the first sorting hole 10a of the first receiving plate 4a is 1st
The first receiving plate 4a falls before the receiving plate 4a, and then the lower edge of the first receiving plate 4a engages with the protrusion 17a of the acceleration belt 17 and is forcibly transferred quickly, approaching the contact body 4d. At this time, the object 3 caught in the first sorting hole 10a falls naturally or comes into contact with the protrusion 4g of the contact member 4d and is pushed out to the rear side of the first receiving plate 4a.

The workpiece 3 that has fallen from the first receiving plate 4a in this way is transferred to the lower belt conveyor 18a and the narrow belt conveyor 19.
It is sent out to the side via a.

On the other hand, the object 3 that is larger than the second sorting hole 10b of the second receiving plate 4b is caught in the second sorting hole 4b, and then the laminated body 4
When it passes through the second guide rod 6b in the second section It is reliably discharged to the side by the belt conveyor 19b.

Further, the object 3 to be treated, which is larger than the third sorting hole 10C of the third receiving plate 4C, is caught in the third sorting hole 10C and further moves along with the stacked body 4 to the third section X3 in front of the third guide plate 4C. Once it passes through the rod 6C, it is sorted in the same manner as the first receiving plate 4a and is discharged to the side.

Then, after circulating around the front end 5A of the transfer body 5 in a suspended state in which all the first to third receiving plates are rotated downward, the transfer body 5 is transferred to the rear end 5B via the return path Y.

In this way, the subsequent stacked bodies 4 are similarly transferred in the sorting section Sort them separately and make sure they fall.

When the stacked body 4 goes around the front end 5A of the transfer body 5, it is reversed, but at this time, the stacked body 4 may come into contact with the shaft 8 of the adjacent stacked body 4, or a foreign object may be caught, and the stacked body 4 will not return to the hanging position. However, since the tip 41a of the presser plate 41 of the pressurizing means 38 presses down, the laminate 4
will surely return to the suspended position, and will not be in a raised state when it is reversed at the rear end 5B of the transfer body 5, but will be reliably reversed, and will be transferred onto the first guide rod 6a in a state where it can be sorted. .

In the above embodiment, the presser plate 41 is used as a pressure means for positioning the laminate 4 in the hanging position on the return path Y, but this is not limitative. Any type of nozzle that injects air may be used.

The shape of the sorting holes in the receiving plate is not limited to round holes, but may be of any shape as long as the objects to be treated can be sorted by size.

Although protrusions and guides are used as guide means for rotating each receiving plate of the stacked body downward at different positions, the present invention is not limited thereto, and other means may be used.

As shown in the embodiments above, the sorting device of the present invention can forcibly press the stacked bodies downward with the pressurizing means on the return path to position the stacked bodies in the hanging position, and when the stacked bodies are reversely transferred. It is possible to reliably return the stacked body to the suspended position due to contact with a shaft or the like or catch of a foreign object, and it is possible to prevent reverse transfer on the transfer path and perform sorting work reliably and efficiently.
