Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention distinguishes 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 Separate the parts into
This invention relates to a sorting device that can be selected.

[Conventional technology]

Manually sorting a specific member according to its shape when a plurality of small and differently shaped members are mixed together is time consuming and prone to erroneous sorting. Therefore, conventionally, various automatic sorting mechanisms have been used that mechanically or electrically classify and select a plurality of types of members according to their shapes. However, with conventional automatic sorting mechanisms, it is relatively easy to construct a sorting mechanism for heavy and somewhat thick members such as coins and nuts; , it is difficult to sort thin members by shape;
A device that completely selects multiple types of members according to their shapes has not yet been developed. For example, the sorting of paper pieces such as tickets, cloth pieces such as scraps, thin metal pieces, etc. has had to be done manually. For this purpose, a large number of rectangular holes are opened in the outer peripheral wall of a cylindrical sorting drum, and multiple types of parts are housed in the sorting drum and rotated to allow parts of a specific shape to pass through the openings. A device for sorting members by shape has also been proposed (for example, Patent Application No. 61308 of 1982). However, in a sorting device using a cylindrical drum, the opening area is small compared to its internal volume, and it is necessary to perform tasks such as loading parts to be sorted and taking out irregularly shaped parts that could not be sorted after the sorting work is completed. This made the process difficult and reduced the efficiency of the sorting work.

[Problems to be Solved by the Invention] In view of the above-mentioned drawbacks, the present invention provides a sorting device that has a large opening area compared to its internal volume and that allows easy loading and unloading of members to be sorted.

[Means for solving problems]

The present invention provides a dish-shaped sorting body having a cone part whose periphery is tapered and expanded outward like a mortar, and a passage provided in the cone part of the sorting body that communicates the inner and outer walls of the sorting body. It consists of a sorting mechanism with a mouth, and a shaft support mechanism that holds a rotary shaft aligned with the axis of the sorting body so as to be rotatable upward at a predetermined angle to the horizontal and at an elevation angle. In a sorting device that is capable of discharging only members with a specific shape from the inner circumference side of the sorting body to the outer circumference side of the sorting body through a shape sorting mechanism by storing members of different shapes and rotating the sorting body in a specific direction. The opening shape of the opening of the shape sorting mechanism is made to almost match the shape of the parts to be sorted, and the opening surface of this opening is positioned slightly perpendicular to the outer circumferential tangent of the cone part of the sorting body. The present invention provides a sorting device characterized in that a guide wall is slightly perpendicularly installed on the inner circumferential surface of the sorter, the guide wall expanding into a figure-eight shape in the direction of rotation of the sorting body and continuing to the opening at the end thereof. be.

[Effect]

In the present invention, a plurality of types of members are introduced through a cone portion having an opening corresponding to the size of the sorting body, and when the sorting body is rotated, the stored members slide on the inner circumferential wall surface of the cone portion. The sliding members are gathered in the direction of the passageway by the guide wall and directed toward the passageway. Then, only the members smaller than the shape of the opening pass through and are discharged from the inside of the sorting body to the outside, and the sorting work is performed.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In this embodiment, a member for sorting rectangular pieces of paper, that is, tickets, according to their size will be explained.

Fig. 1 shows the external appearance of the sorting device according to this embodiment.The main body 1 has a vertically elongated cubic shape, and the upper front part thereof is cut diagonally to form an inclined work panel 2. A circular input window 3 is opened through the center of the main body 1, and a sorting body 4 shaped like a deep dish is provided in the main body 1 close to the input window 3. A rectangular sliding opening 5 is opened at the lower front of the main body 1, and a box-shaped collection box 6 with an upper opening is inserted into the sliding opening 5 so as to be freely inserted and removed. A control box 7 in which switches, lamps, etc. are fixed is provided above the sliding port 5 on the front surface of the slider 1.

Figure 2 shows a cross section of the main body 1 cut in the longitudinal direction. A support plate 8 continuously bent into a dogleg shape and an L shape is fixed toward the center, and the interior space of the main body 1 is divided into an upper rear motor chamber 9 and a recovery chamber 10 by this support plate 8. That will happen.
A motor 11 is fixed at the center of the support plate 8, and the motor shaft 12 of the motor 11 is inclined upward at about 45 degrees with respect to the horizontal line, and its axis is aligned with the center of the input window 3. There is. and,
In the middle of the support plate 8, there is a shaft opening 13 facing the input window 3.
is opened, and the motor shaft 12 is inserted into this shaft opening 13.
A flange-shaped drive fitting 14 fixed to is inserted therethrough. The rear center of the sorting body 4 is fixed to the drive fitting 14 with their axes aligned.
The motor shaft 12, drive fitting 14, and sorting body 4 can rotate together.

FIG. 3 shows the sorting body 4 in detail. The sorting body 4 has a hollow shape with a truncated conical outer shape, and is formed by welding or pressing a thin sheet metal. The sorting body 4 is composed of a bottom plate 15, a cone plate 16 as a cone portion, and an edge plate 17. The bottom plate 15 is disk-shaped, and a flange-shaped drive fitting 14 is attached to the center of one side thereof by screws. The cone plate 16 has the shape of a hollow cone body cut in parallel, and its inner diameter increases outward, and its inclination angle is 90°.
The bottom plate 15 is fixed to the smaller inner diameter side. The edge plate 17 has a thin ring shape with an opening having approximately the same diameter as the input window 3 in the center, and its outer edge is connected to the enlarged end surface of the cone plate 16. 1
6. A deep dish-shaped sorting body 4 is formed with the bottom closed by the edge plate 17 and the top largely open. The sorting mechanism 1 has a predetermined opening shape at intervals on the inclined peripheral surface of the cone plate 16.
8 is provided.

FIG. 4 is a detailed explanation of the sorting mechanism 18, in which sliding surfaces 19 shaped like Mt. Fuji are arranged at intervals in the circumferential direction of the cone plate 16 at an enlarged portion (corresponding to the foot portion of Mt. ), and each sliding surface 19 has a cone plate 16.
It is slightly inclined and protrudes outward. On both sides of the semi-parabolic punched sliding surface 19, thin and elongated guide plates 20 are installed on the cone plate 16.
The pair of band-like guide plates 20 form a hyperbolic shutter. That is, the lower surface of one end of the guide plate 20 is located on both sides of the peak of the sliding surface 19 shaped like Mt. Fuji, and the upper surface of the other end of the guide plate 20 is located on the sliding surface 19.
The discharge port 21 is located at the minimum opening cut out of the guide plate 20, and a rectangular outlet 21 is formed by the height H of the other end of the guide plate 20 and the width L of the top of the sliding surface 19.
The lower part of one end of the guide plate 20 is made to stand up on the inner peripheral surface of the cone plate 16. The cross-sectional shape of the outlet 21 formed as described above is specified in advance, and the width L and height H are set to predetermined dimensions according to the members to be sorted.

Next, the operation of this embodiment will be explained.

In this example, there are two types of tickets A and B whose shapes differ depending on the face value of the printed amount.
This section explains how to select. First, when mixed tickets A and B are thrown in through the input window 3, the tickets A and B are stored in a dish-shaped internal space in the sorter 4. When a predetermined amount of tickets A and B are stored in the sorting body 4, the switch in the control box 7 is operated, and the motor 11 is activated, and the motor shaft 12, the drive fitting 14 operated by this, and the sorting body 4 are rotated. , and its rotation direction is the X direction in the figure. Therefore,
The sorting body 4 rotates with the enlarged part of the sliding surface 19 at the front and the discharge port 21 at the rear, and the mixed tickets A and B are slid and stirred on the inner peripheral surface of the cone plate 16 of the sorting body 4. Become. As mentioned above, the motor shaft 12 is inclined upward at an angle of 45 degrees from the horizontal, and the cone plate 16 is inclined at an angle of 90 degrees.
The inner circumferential lower surface of the cone plate 16 is horizontal, and the inner circumferential upper surface is vertical. Therefore, the tickets A and B are accumulated on the lower inner periphery of the cone board 16 due to their weight, and regardless of their size, the tickets A and B are always in somewhat horizontal contact with the lower inner periphery of the cone board 16. It will slide. These tickets A and B are cone board 16
When sliding on the inner circumferential surface of the ticket outlet, each ticket A, B is scraped together in the direction of the sliding surface 19 by the guide plate 20, which is enlarged left and right in the direction of rotation, and while sliding on this sliding surface 19, the tickets A and B are scraped together in the direction of the sliding surface 19. Move to 21.
However, since the opening cross-sectional shape (H x L) of the discharge port 21 is preset, only the ticket A whose shape is smaller than the cross section of the discharge port 21 passes through the discharge port 21 and exits the sorting body 4. It is discharged, falls downward, and is retained in the collection box 6. Ticket B, which is larger in shape than ticket A, cannot pass through the outlet 21 because it is larger than the cross-sectional shape of the opening of the outlet 21, and is caught on the guide plates 20 on both sides in front of the outlet 21, but it flows and passes through the outlet 21. Since the ticket B is flipped upward, the ticket B remains in the sorter 4.

In this way, tickets A and B of different shapes are separated and sorted according to the shape of the discharge port 21 of the sorting body 4, and only the small-shaped ticket A is discharged below the sorting body 4, while the large-shaped ticket B remains in the sorting body 4. When the sorting is completed after a predetermined period of time has elapsed, the drive of the motor 11 is stopped using a timer or the like, and after stopping the sorting operation, the collection box 6 is pulled out to the front to collect the tickets A stored therein. can be transferred to other storage equipment. In addition, the sorting body 4
The remaining tickets B can be taken out by inserting your hand through the input window 3 or taken out of the sorting body 4 using a vacuum suction machine, and can be stored separately from the tickets 4.

〔Effect of the invention〕

Since the present invention is configured as described above, it is possible to classify and sort light and thin members according to the size of their shapes, which could not be sorted in the past, and to classify them into each type manually. Effective sorting can be performed in a short time regardless of the work involved. The input port of the sorting body into which the parts to be sorted are inputted has a large opening and is slanted toward the front, making it possible to secure a large opening area compared to the internal volume, making it easy to input and collect the parts. This improves work efficiency.
