Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves determining the size of multiple types of thin plate-like members with different shapes, such as pieces of paper, pieces of metal, coins, etc., according to their shapes, and separating and selecting part I for each shape. Made 71
The present invention relates to a sorting device, and particularly relates to a sorting device that can facilitate post-processing by storing a plurality of sorted members according to their shapes.

Manually sorting a large number of parts that are small and have a mixture of different shapes according to their shapes is time consuming and easy to separate. Therefore, conventionally, multiple types of mechanical and electrical defects have been classified according to their shapes.

An automatic sorting mechanism was used to select each product. However, with conventional automatic sorting mechanisms, it is relatively easy to construct a sorting mechanism for coins, nuts, etc., which are medium-sized and have a certain thickness, but they are light and heavy. , and it is difficult to sort by shape for thin members.
A device that completely selects multiple types of members according to their shapes has not been developed. For example, it was advantageous not to rely on manual labor for sorting paper pieces such as tickets, cloth pieces such as scraps, and thin metal pieces. For this purpose, a hole with a specific shape is opened through the outer periphery of the sorting drum, which has a hollow cylindrical shape, so that only the members of a specific shape are discharged from the hole among the multiple types of materials stored in the sorting drum. A sorting device for selecting these members has also been proposed. However, with this device, it is not possible to separately house and store a plurality of sorted members (the remaining members remain in the drum), and post-processing after sorting is not easy.

In view of the above-mentioned drawbacks, the present invention makes it possible to sort lightweight and thin-walled members according to their shapes, and to facilitate post-processing by separately storing members with different shapes after sorting. The objective is to provide a sorting device that can.

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings.

．． 21 and is held by support means separate from the sorting drum 14.

Next, the operation of this embodiment will be explained.

In this embodiment, we will explain the case where tickets A and B of different sizes are sorted as shown in Fig. 5, and the widths of the short sides of tickets A and B are set to X and Y, respectively. be. First, to select small tickets A, set the sorting device to the state shown in FIG. and stored inside the sorting drum 14 in the main body 1. After storing a predetermined amount of tickets A and B in the sorting drum 14,
When the switch on the control panel 7 is turned on, the motor 16 starts, rotates the drive shaft 15, and rotates the sorting drum 14 in the direction of arrow F in the figure. Therefore, the sorting drum 14 rotates with the enlarged end of the guide plate 32 of the shape sorting mechanism 2o as the leading end of rotation, and the discharge port 34 as the rear end.
The mixed tickets A and B are slid and stirred on the inner peripheral surface of the sorting drum 14 (8). Therefore, tickets A and B are stored in the sorting drum 14.
It slides by zero rotation, and is always located below the sorting drum 14 due to its weight, and is scraped in the direction of the discharge slot 34 by contacting the guide plate 32. That is, the tickets A and B slide on the inner peripheral surface of the sorting drum 14 regardless of their shape, and the tickets A and B slide on the inner peripheral surface of the sorting drum 14, and the tickets A and B slide on the inner peripheral surface of the sorting drum 14.
2 regulates the flow direction, and the flow is directed by guide plate 3
2 towards the narrowed center. In this way, the tickets A and B flow toward the center of each shape sorting mechanism 20, and the tickets A and B are always collected between the pair of guide plates 32. The tickets A and II collected between the guide plates 32 flow through the sliding part 30 and reach the discharge port 34, but the discharge port 34 is previously formed to a predetermined length V and has a shape. Only small tickets A pass through the discharge port 34 and are discharged to the outside of the sorting drum 14. However, since the ticket B, which is larger in shape than the ticket A, is larger than the cross-sectional shape of the outlet 34, it either gets caught on the guide plates 32 on both sides before the outlet 34, or it flows and is thrown up above the outlet 34.
The tickets A do not pass through the discharge port 34 and remain inside the sorting drum 4 (r).The tickets A discharged from the discharge port 34 on the outer periphery of the sorting drum 14 enter the space of the U-shaped cross section of the ring portion 26 of the collection guide 22. It slips on the inner circumferential surface of the ring part 26, flows into the chute part 28, and due to its own weight falls into the collection box 4 through the outlet opened at the bottom of the chute part 28, where it is collected. Become.

Next, the sorting drum 14 is rotated in the direction of arrow F for a predetermined period of time, and when all the small tickets A are ejected and large tickets B remain, the motor 16 is stopped by a timer or the like, and the control panel 7 is operated. Then, the motor 16 is driven in the reverse direction, the sorting drum 14 is rotated in the reverse direction in the direction of arrow G, and the ticket B is slid and stirred within the sorting drum 14. Therefore, the tickets Bki flow toward the center of the shape sorting mechanism 21 in the same manner as described above, and the tickets B are collected between the pair of guide plates 33, pass through the large ticket B discharge port 35, and are sent to the sorting drum 14. It enters the space of the U-shaped cross section of the ring part 27 of the recovery guide 23, slides on the inner circumferential surface of the ring part 27, flows to the chute part 29, and by its self 1 flows into the chute part 29. It falls into the collection box 5 through the discharge port opened at the bottom and is collected therein.

In this way, only the ticket A is collected separately in the collection box 4, and only the ticket B is collected in the collection box 5, and they are stored separately.

After driving the motor 16 for a predetermined period of time, the drive of the motor 16 is stopped using a timer or the like, and when the rotation of the sorting drum 14 is stopped, the ticket B is stored in the collection box 3 and the sorting drum 1 is stopped.
Items that cannot be sorted, such as scrap paper bills and defective tickets, will remain in the box.

Next, when this series of sorting operations is completed, the equipment must be cleaned in order to perform the next sorting operation. First, pull out the collection boxes 4 and 5 and transfer the tickets A and B stored in the respective collection boxes 4 and 5 to their respective storage devices, manage the tickets A and B separately, and store them in the prescribed manner. Dispose of it by incinerating or cutting it up depending on the season. Then, by rotating the input body 9 around the hinge 10 as shown in FIG. 2, the opening 13 is exposed, and the sorting drum 14 is exposed through the opening 13.
Insert your hand inside the drum or use a vacuum suction machine to remove the unsortable parts from the sorting drum 14 and collect tickets A and B.
It can be stored separately from the Then, each of the collection boxes 4 and 5 is inserted into the device, and the input body 9 is attached to the hinge 10.
By rotating it around the center to return it to the state shown in FIG. 1, it is possible to prepare for the next sorting operation.

Since the present invention is configured as described above, it is possible to classify lightweight and thin members according to the size of their shapes, which was difficult to sort in the past, and to classify them according to their shapes. , it is possible to perform effective sorting in a short time without manual labor.

Since multiple parts separated by shape can be stored individually, they can be separated,
Post-processing after accumulation becomes extremely easy.
