Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is for sorting multiple types of thin plate-like members with different shapes, such as paper pieces, metal pieces, hard pieces, etc., according to their shapes, The present invention relates to a sorting device that can facilitate the collection of members after they are sorted.

[Conventional technology]

Manually sorting a large number of small-shaped members in which a plurality of different shapes are mixed together according to their shapes is time-consuming and prone to erroneous sorting. Therefore, conventionally, multiple types of mechanical and electrical components have been classified according to their shapes.
Various automatic sorting mechanisms were used.

However, in the conventional automatic sorting mechanism, the sorting mechanism can be constructed relatively easily for heavy and thick members such as coins and nuts, but it is lightweight and It is difficult to sort thin members by shape, and no device has been developed that can completely sort multiple types of members by shape. For example, paper pieces such as tickets, cloth pieces such as scraps, thin metal pieces, etc., have to be sorted manually.

In order to sort such lightweight, thin-walled pieces, it has often been used to move the parts to be sorted using a belt or the like and feed them into the sorting mechanism, or to blow up the parts with air and introduce them into the sorting port. However, either method is inefficient because it is not possible to transport a large amount of materials to be sorted in a short time.

For this reason, a sorting device has also been proposed in which a shape sorting mechanism is fixed to the outer periphery of a cylindrical drum body having a hollow interior and a shape sorting mechanism that allows only thin pieces of a specific shape to pass through. For example, Japanese Patent Publication No. 80379 (1982)
No. 36580 of 1982, 177186 of 1981,
186482 of 1982, 205571 of 1982, 214380 of 1982, 16580 of 1980, JP 59 of 1983
112881, 1982, and JP-A No. 19084, 1986.

In these newly proposed sorting devices, an aperture of a specific shape is formed on the outer periphery of an internally hollow drum body, and members of different shapes housed in the drum body are rotated within the drum body to allow them to pass through the aperture. Only members of a specific shape were released and sorted.

However, with this newly proposed sorting device, it is easy to discharge the sorted parts of a certain shape, but it is easy to discharge the sorted parts of a certain shape, but the parts of other shapes or garbage remaining in the drum, or of other completely different types, can be discharged. It was difficult to release the parts, and the cleaning and collection work after the sorting work was completed was complicated.

[Problem to be solved by the invention]

In view of the above-mentioned drawbacks, the present invention has been developed in such a way that, in the work of sorting out a plurality of types of members stored in a drum body, members of a specific shape are received by a first collecting means and remain in the drum body after the sorting work is completed. The purpose of this is to tilt the drum body and receive other members or dirt by the second collection means to facilitate cleaning and maintenance.

[Means for solving problems]

The present invention includes a drum body that is hollow inside and has a slightly cylindrical shape, and is rotatably held around the axis of the cylinder, and a guide wall that is enlarged and provided in a V-shape on the peripheral wall of the drum body. At the reduced end of this guide wall, there is a hole that is opened slightly perpendicular to the tangent to the outer circumference of the drum body and allows only members of a specific shape to pass through, and in order to swing this drum body up and down,
an auxiliary shaft support whose rotation direction is perpendicular to the rotation axis of the drum body and held horizontally; and a horizontally movable means located below the drum body to receive the member released from the opening. A first collection means, located below the first collection means, whose surface is always covered by the first collection means, but is exposed by moving the first collection means. The present invention provides a sorting device comprising a horizontally movable second collection means that receives the members discharged from the side opening of the drum body which has been overturned.

[Effect]

In the present invention, different types of members are housed in the drum body, and by rotating the drum body in a certain direction, the members are slid in the direction in which the guide wall is enlarged, and the members are moved to the end of the V-shape of the guide wall. Only members with a specific shape are sequentially discharged from the opening, and only the members with the specific shape are first sorted. Then, the ejected member having a specific shape falls onto the first collecting means located horizontally below the drum body and is collected.

Next, the first collecting means is pulled out horizontally to expose the upper surface of the second collecting means. Since the drum body is supported by horizontal auxiliary support means in a direction substantially perpendicular to its rotational axis, the drum body can be tilted with its side opening facing downward. All the members remaining in the drum body then fall onto the second collecting means and are collected. As a result, other types of members, garbage, or irregularly shaped members remaining inside the drum body that could not be sorted during the sorting work are discharged downward,
This can facilitate cleaning and collection work.

A rectangular sorting body 2 with an open bottom is fitted between the side plates 6 and 7, and a holding shaft 9 serving as an auxiliary support means is inserted in the center between the side plates 6 and 7 and the side surface of the sorting body 2. They are connected to be rotatable in the vertical direction.

Further, the side surface of the front door 3 is connected to the front end surface of the side plate 7 by a hinge 10 so as to be horizontally rotatable. The front door 3 has a panel shape with a width approximately equal to the interval between the side plates 6 and 7 and a height equal to the length from the upper end of the front panel 8 to the upper surface of the sorting body 2. . A hopper 11 that is gently sloped downward is attached to the upper front half of the front door 3.
An inlet 12 is opened at the bottom of the sorting body 1 and is opened toward the center of one end of the sorting body 2. Further, at a position below the hopper 11, a transparent observation window 13 is attached to the front door 3 through which the inside of the sorting body 2 can be observed.

Next, on the front panel 8, an upper collection box 4 and a lower collection box 5 are stored in two stages, upper and lower, so that they can be pulled out horizontally. There are no shelves or the like, and when the upper collection box 4 is pulled out, there is no obstacle between the lower part of the sorting body 2 and the lower collection box 5. A sorting drum 14 as a cylindrical drum body is rotatably housed inside the sorting body 2, and the axial direction of this sorting drum 14 is perpendicular to the holding shaft 9. The opening at one end of the sorting drum 14 is aligned approximately with the center of the introduction port 12.

Next, the structure of the sorting drum 14 housed in the sorting body 2 and its surrounding structure will be explained with reference to FIG.

The sorting drum 14 is formed by winding a thin metal material into a cylindrical shape, and is hollow inside. One end (left side in the figure) is closed, but the other end (right side in the figure) is open. A drive shaft 15 is connected to the center of one end, and a motor 16 is connected to the drive shaft 15. Support shafts 17, 18, 19, and 20 are arranged on the top, bottom, right, and left sides of the sorting drum 14 at a slight interval from the outer periphery of the sorting drum 14, and these support shafts 17, 18, 19, and 20 are connected to the sorting bodies, respectively. It is pivoted on 2. Rollers 21, 22, 23, 24 are fixed to the front, back, and center of each support shaft 17, 18, 19, 20, respectively.
4 is brought into contact with the outer periphery of the sorting drum 14, and the sorting drum is rotatably held by these rollers 21, 22, 23, and 24. On the outer periphery of the sorting drum 14, a plurality of sorting mechanisms 25 are formed in a row parallel to the axial direction of the sorting drum 14 at equal intervals. In this embodiment, there are four sorting mechanisms 25 in a row.
The sorting mechanisms 25 are individually formed and have two adjacent locations.
are arranged close to each other as a set of two.

Further, a thin ring 30 is fixed to the inner peripheral surface of the sorting drum 14 at a position close to the opening end surface, and a receiving metal fitting 31 is fixed to this ring 30 at an interval of 120 degrees. be. The reference numeral 32 designates a thin plate-like stop plate, and the stop plate 32 is circular, and its outer diameter is approximately the same as the inner diameter of the holder 31. An aperture 33 of approximately 100 mm is passed through. Locking metal fittings 34 are fixed to the outer circumference of this stop plate 32 at intervals of 120 degrees, and the receiving metal fittings 31 and locking metal fittings 34 can be combined so that they can be detachably engaged. .

FIG. 4 is an enlarged view of the sorting mechanisms 25, which are arranged in pairs.

Each sorting mechanism 25 is formed by punching out the outer periphery of the sorting drum 14 and gluing a thin, elongated band plate to the punched out portion.
The sorting drum 14 has a sliding part 26 in the shape of Mt. Fuji punched out into a slightly trapezoidal shape for each sorting mechanism 25, and a bullet-shaped branch part 2 with an acute angle at the tip.
7, and the sliding portion 26 is formed into a parabolic shape with both ends approaching each other, and is bent while being inclined outward from the circular outer periphery of the sorting drum 14. An elongated band-shaped guide plate 28 is fixed to the parabolic cut portion on both sides of each sliding portion 26 over the entire length thereof, and the guide plate 28 forms a shooter of a hyperbolic member. become.

That is, one end of the guide plate 28 is located on both sides of the peak of the sliding portion 26 shaped like Mt. Fuji, and the guide plate 28
The other end is located at the largest opening of the sliding section 26, and is connected to one end of the guide plate 28 and the sliding section 26.
The apex of the guide plate 28 has a rectangular shape and forms a discharge port 29, and the lower part of the other end of the guide plate 28 stands up on the inner periphery of the sorting drum 14. Then, the adjacent sorting mechanism 25
The other ends of the guide plates 28 are connected to each other, and the branch part 2
It is V-shaped so as to surround the number 7. Also,
The cross-sectional shape of the formed discharge port 29 is specified in advance, and the width L and height H are set to predetermined dimensions.

Next, the operation of this embodiment will be explained.

In this example, tickets A and B of different sizes are used.
I will explain the process of sorting. This ticket A,
B are different in size; ticket A has a width of X, ticket B has a width of Y, and X is smaller than Y. Further, the width L of the discharge port 29 is set to be slightly larger than the width X of the ticket A and narrower than the width Y of the ticket B.

First, in the sorting work, the sorting device is set in the state shown in FIG. Tickets A and B inserted from the hopper 11 follow the inclination of the hopper 11 and enter the inlet 12.
direction, and is discharged into the sorting body 2 through the opening of the inlet 12. Since the axis of the introduction port 12 is aligned with the opening 33 of the stop plate 32, the tickets A and B pass through the opening 33 and are stored in the sorting drum 14. Once a predetermined amount of tickets A and B have been stored in the sorting drum 14, the power switch is turned on, the motor 16 is started, the drive shaft 15 is rotated, and the sorting drum 14 is rotated in the direction of arrow T in FIG. 3. .

Therefore, the sorting drum 14 rotates with the V-shaped top of the branching part 27 of the sorting mechanism 25 as the tip of rotation and the discharge port 29 as the rear end, and the mixed and stored tickets A and B are transferred to the sorting drum. 14 is subjected to sliding agitation on the inner circumferential surface. Therefore, the tickets A and B slide due to the rotation of the sorting drum 14,
Due to its weight, it is always located below the sorting drum 14, and by contacting the guide plate 28, the discharge port 29
It will be raked in the direction. That is, the tickets A and B slide on the inner circumferential surface of the sorting drum 14 regardless of their shape, and their flow direction is regulated by the guide plate 28, which has large openings on the left and right.
The flow in the Q and R directions is directed toward the center of the guide plate 28.

Adjacent guide plate 28 formed here in a V-shape
Tickets A and B that entered from direction T are on the guide board 28.
It branches at the top and is distributed to the left and right in the Q direction. Sorted to the left and right in the Q direction, each sorting mechanism 2
5, the tickets A and B are always collected between the pair of guide plates 28. Tickets A and B collected between this information board 28
flows through the sliding part 26 and reaches the discharge port 29, but this discharge port 29 is previously formed to a predetermined size, and only the ticket A whose width is smaller than the width L of the discharge port 29 flows in the direction of the arrow S. It flows, passes through the discharge port 29, and is discharged to the outside of the sorting drum 14.

However, since the ticket B whose shape is larger than the width L of the discharge port 29 is larger than the cross-sectional shape of the discharge port 29, it may get caught on the guide plates 28 on both sides before the discharge port 29, or may flow and flow out of the discharge port 29. Since the tickets are bounced upward, they do not pass through the discharge port 29 and remain in the sorting drum 14 (in this embodiment, the size of the tickets A and B is set depending on the size of the displayed price). There are two types of shapes). The tickets A that have passed through the discharge port 29 are discharged from the lower part of the sorting body into the space within the base 1, fall into the upper collection box 4, and are collected. Also, the ticket A is slid toward the branching part 27, and the R in FIG.
If it slips between the guide plates 28 as in the direction shown in FIG.

After operating the motor 16 for a predetermined period of time to select only the tickets A, the motor 16 is stopped and the rotating operation of the sorting drum 14 is stopped. During this sorting operation, the interior of the sorting drum 14 can be directly observed through the transparent observation window 13 provided in the front door 3, so the progress of sorting can be observed, and once the sorting has been completed to a certain extent, The motor 16 can also be stopped at the discretion of the operator.

Next, to explain how to collect the large tickets B remaining in the sorting drum 14, first, the upper collection box 4 is pulled out horizontally, and the tickets A stored in the upper collection box 4 are stored. Alternatively, the lower collection box 5 is stored in the base 1 for the next disposal such as cutting.

Thereafter, the front door 3 is largely rotated in the horizontal direction along the top plate 10 to release the front surface of the sorting body 2 and one end of the sorting drum 14. Then, the lock fittings 34 of the stop plate 32 fixed to one end of the opening side of the sorting drum 14 are rotated to release the engagement with the receiving metal fittings 31, and the stop plate 32 is removed from one end of the sorting drum 14. Therefore, one end of the front surface of the sorting drum 14 is left wide open. When the sorting body 2 is tilted downward along the holding shaft 9, the sorting drum 14 is also tilted downward at the same time, and the tickets B and garbage remaining in the sorting drum 14 are removed from the inner wall of the sorting drum 14. It will slip and fall into the lower collection box 5, where it will be collected.

If the ticket B or the like is caught in the sorting drum 14, a broom is inserted into the sorting drum 14 to scrape it out, or compressed air is blown to force it to slide off. As a result, sorting drum 1
All the tickets B, garbage, oddly shaped parts, etc. remaining in the box 4 are stored in the lower collection box 5. Then, this lower collection box 5 is pulled out from the base 1 and transferred to a storage box for tickets B, and cleaning of the inside of the sorting drum 14 and collection of tickets B are completed.

Next, in order to perform the sorting operation again, the upper storage box 4 and the lower storage box 5 are each inserted into the base 1, and the sorting body 2 is rotated along the holding shaft 9 to return to the horizontal position. Thereafter, the front door 3 is rotated horizontally to attach it to the side surface of the sorting body 2 and the base 1. This allows you to move on to the next sorting operation.

〔Effect of the invention〕

Since the present invention is configured as described above, when the drum body is rotated, the housed members slide on the inner wall of the drum body and are simultaneously guided into the V-shaped interior formed by the guide wall. Since an opening is formed at the end of this guide wall, the member having a specific shape passes through this opening and falls onto the first collecting means. Further, since the drum body can be tilted up and down by the horizontal auxiliary shaft support means, after the drum body has selected only members of a predetermined shape, it is possible to overturn the drum body with the side opening facing downward. This overturn causes other members, dirt, etc. remaining in the drum body to fall onto the second collecting means, and the members inside the drum body can be easily collected in one operation. in this way,
The inside of the drum body can be cleaned extremely easily, improving the efficiency of sorting work, and the drum body can be used cleanly at all times without any irregularly shaped parts, dust, etc. remaining inside the drum body. .
