Description

DETAILED DESCRIPTION OF THE INVENTION The present invention distinguishes the size of a plurality of thin plate-shaped members having different shapes, such as pieces of paper, pieces of metal, coins, etc. according to their shapes, and separates the members according to their shapes.
The present invention relates to a sorting device that can be selected, and particularly relates to a sorting device that can sort a plurality of types of members depending on the rotation direction of a sorting drum by changing the rotation direction of the sorting drum.

Conventionally, an automated parts feeder has generally been used to select only parts with a specific shape from a mixture of parts of a plurality of different shapes. Among these, for relatively small and thin parts, for example, there is a bowl-shaped parts feeder in which a fixed gate is installed in the upper bowl and the irregularly shaped parts are removed from the bowl depending on whether or not they can pass, or parts are transported on a straight track. It is conveyed by a belt, or by swinging a horizontal plate provided with a drop port, and a mechanism that determines the size of the drop depending on the size of the shape. A feeder or the like has been devised in which a specific member is discharged by centrifugal force by being placed in the same direction and rotating at high speed. However, for parts like used tickets that are light, flexible, and easy to bend, and whose shape has slightly deformed, trying to forcefully eject them from the exit can easily cause damage or breakage. Moreover, rather than the fine local deformation that is common in tickets after use, the deformation caused large deformations. For this reason, it is difficult for conventional component sorting and supply devices to efficiently sort relatively narrow boarding tickets and wider tickets such as coupon tickets due to their differences in shape. Ta.

For this purpose, a plurality of holes of a specific shape are opened on the outer periphery of the drum, which has a hollow cylindrical shape, and a plurality of ticket pieces of different shapes are stored inside this drum, and the drum is rotated. , a sorting device has been proposed that can sort out ticket pieces by discharging only ticket pieces of a specific shape from an opening (for example, Patent Application No. 61308 of 1982). However, with this structure, although it is possible to sort a single type of ticket, it is not possible to sort other types of ticket.If you want to sort multiple types of ticket, you need to install a dedicated drum for each type and sequentially separate them. This was inconvenient as it required further selection work. For this reason, the sorting work is limited to only a single type of material using the same drum,
There has been a desire for a device that can sort multiple types of components using a single drum.

In view of the above-mentioned drawbacks, the present invention provides a single drum with multiple types of shape sorting mechanisms, and is capable of sorting lightweight and thin members according to their shapes, as well as members that are sorted according to the rotational direction of the drum. The present invention provides a sorting device that can distinguish between different types.

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

In this example, the members to be sorted are rectangular pieces of paper,
In other words, a method for sorting tickets based on the size of their shape will be explained.

FIG. 1 shows the external appearance of the sorting device of this embodiment, in which a pair of legs 2 are vertically connected at a distance at the bottom of a rectangular main body 1. A collection box 3, which is hollow inside and open at the top, is housed between the boxes and can be freely moved forward and backward. A control panel 4 equipped with switches, lamps, etc. is provided on a part of the side surface of the main body 1, and an input body 5 is connected to the short side of the upper end of the main body 1 by a hinge 6.
The input body 5 has a trapezoidal opening at the top and a triangular shape narrowing downward.The input port 7 has a large opening on the side closer to the main body 1. A chute 8 protruding from the inlet 7 into the main body 1 is provided at an inclined position in the lower part of the interior. Also, Figure 2 shows the collection box 3 in Figure 1.
This figure shows a state in which the input body 5 is rotated onto the upper surface of the main body 1 by means of a hinge 6 with the input body 5 being pulled out forward.
A circular opening 9 is formed in the side surface of the main body 1 on which the input body 5 is provided, and the inside and outside of the main body 1 communicate with each other through this opening 9.
The side opening ends of the sorting drum 10 housed inside are brought close to each other.

Next, FIG. 3 explains this sorting drum 10 in detail. The sorting drum 10 is formed by winding a thin metal material into a pipe shape, and is hollow inside. ) is wide open, but the other end (right side in the figure) is closed. A drive shaft 11 is connected to the center of the other end, and the drive shaft 11 is connected to a motor 12. The sorting drum 10 is installed so that its axis is horizontal,
Support shafts 13, 14, and 15 are supported at intervals on the left and right sides of the upper and lower parts of the sorting drum 10, and rollers 16, 17, and 18 are fixed to the left and right sides of each of the support shafts 13, 14, and 15, respectively. Each of the rollers 16, 17, and 18 is brought into contact with the outer periphery of the sorting drum 10 to rotatably hold the sorting drum 10. On the outer periphery of the sorting drum 10, two types of shape sorting mechanisms 19 and 20 are provided at intervals in each row in the axial direction, and in this embodiment, there are four shape sorting mechanisms 19 per row; Shape sorting mechanism 2
Three 0's are provided respectively. FIG. 4 is an enlarged view of a part of the shape sorting mechanisms 19, 20. Each shape sorting mechanism 19, 20 punches out the outer periphery of the sorting drum 10, and fills the punched portion with a thin, elongated shape. Both shape sorting mechanisms 19 and 20 have the same structure although their sizes are different, and the shape sorting mechanisms 19 and 20 are arranged symmetrically. There is. Each sorting drum 10 has one shape sorting mechanism 1.
Punch out and cut into a slightly trapezoidal shape for 9 and 20,
As a result, Mt. Fuji-shaped sliding parts 21, 22 and bullet-shaped branch parts 23, 24 with acute angle tips are processed, and the sliding parts 21, 22 have a parabolic shape in which both sides approach each other. It is curved and bent outward from the circular outer periphery of the sorting drum 10. Each sliding part 21, 22
Elongated band-shaped guide plates 25 and 26 are fixed to the parabolic cut portions on both sides of the cut part over the entire length thereof, and the sliding part 21 and the guide plate 25, and the sliding part 22 and the guide plate 26 A hyperbolic ticket shooter is formed. That is, one end of each of the guide plates 25, 26 is located on both sides of the peaks of the sliding parts 21, 22 shaped like Mt. The guide plates 25 and 26 are located at a certain maximum opening, thereby forming rectangular outlets 27 and 28 at one end of the guide plates 25 and 26 and the tops of the sliding parts 21 and 22. The lower part of the other end of 26 stands up on the inner periphery of the sorting drum 10. Then, the guide plates 25 and 26 of the adjacent sorting mechanisms 19 and 20
The other ends are connected to each other, forming a V-shape surrounding the branch portions 24 and 25. The widths V and W of the aforementioned discharge ports 27 and 28 are set to predetermined lengths, and the width V is set to be larger than the width X of the small ticket A and smaller than the width Y of the medium ticket B. The width W is set to be larger than the width Y of the medium ticket B and smaller than the width Z of the large ticket C. The openings of the discharge ports 27 and 28 are perpendicular to the tangent of the sorting drum 10.
7 and 28 are arranged alternately with their opening directions facing each other.

Next, the operation of this embodiment will be explained.

In this embodiment, large, medium and small tickets A, which have different shapes,
The case where B and C are selected will be explained.

First, to select the small ticket A, set the sorting device to the state shown in Figure 1, and when the mixed large and small tickets A, B, and C are thrown into the upper opening of the input unit 5, the tickets A, B, and C are It is guided through the chute 8 and stored inside the sorting drum 10 inside the main body 1. Once a predetermined amount of tickets A, B, and C have been stored in the sorting drum 10, when the switch on the control panel 4 is turned on, the motor 12 starts, rotates the drive shaft 11, and moves the sorting drum 10 in the direction of arrow F in the figure. Rotate. Therefore, the sorting drum 10 uses the top of the V-shape of the branch part 24 of the shape sorting mechanism 19 as the tip of rotation, and the discharge port 2
7 as the rear end, the mixed tickets A, B, and C are slid and stirred on the inner peripheral surface of the sorting drum 10. Therefore, tickets A, B, C
slides as the sorting drum 10 rotates, and is always located below the sorting drum 10 due to its weight,
By coming into contact with the guide plate 25, the waste is collected in the direction of the discharge port 27. That is, the tickets A, B, and C slide on the inner peripheral surface of the sorting drum 10 regardless of their shape, and their flow direction is regulated by the guide plate 25 that has large openings on the left and right. oriented towards the central direction. In this way, the tickets A, B, and C flow toward the center of each shape sorting mechanism 19, and the tickets A, B, and C are always collected between the pair of guide plates 25. Tickets A, B, and C collected between the guide plates 25 flow through the sliding part 21 to the discharge port 2.
This discharge port 27 is previously formed to a predetermined size, and only the smallest ticket A passes through the discharge port 21 and is discharged to the outside of the sorting drum 10. However, since tickets B and C, which are larger in shape than ticket A, are larger than the cross-sectional shape of this outlet 27, the guide plates on both sides
5 or flow and be thrown up above the discharge port 27, so that they remain in the sorting drum 10 without passing through the discharge port 27. The sorting drum 10 is rotated in the direction of arrow F for a predetermined period of time, and when all the small tickets A have been discharged, the drive of the motor 12 is stopped by a timer or the like, and the collection box 3 is pulled out to the front and the tickets A are placed in another box. Store it in the collection box 3
is emptied, and the collection box 3 is inserted into the lower part of the main body 1 again. Then, operate the control panel 4 to control the motor 1.
2 to reversely rotate the sorting drum 10 in the direction of arrow G, and slide the tickets B and C inside the sorting drum 10.
Stir. Therefore, the tickets B and C flow toward the center of the shape sorting mechanism 20 in the same way as described above.
Tickets B and C are collected between a pair of information boards 26,
The medium-sized ticket B will pass through the discharge port 28 and be discharged to the outside of the sorting drum 10, and only the large-sized ticket C will remain inside the sorting drum 10. After driving the motor 12 for a predetermined period of time, the driving of the motor 12 is stopped using a timer or the like, and the sorting drum 10
When the rotation is stopped, the ticket B is stored in the collection box 3, and the ticket C remains in the sorting drum 10. By pulling out the collection box 3 toward the front, the tickets B stored inside can be transferred to another storage device. In addition, by rotating the input body 5 around the hinge 6 as shown in FIG. 2, the opening 9 is exposed, and by inserting a hand into the sorting drum 10 through this opening 9, or by using a vacuum suction machine. Tickets C can be taken out from the sorting drum 10 and stored separately from tickets A (in this embodiment, tickets A, B, and C are arranged in different sizes depending on their displayed prices). Yes, there are 3 types of shapes
type).

In this way, three types of tickets A, with different shapes,
B and C are separated and sorted by the discharge ports 27 and 28 of the sorting drum 10, and can be stored and stored separately.

Since the present invention is configured as described above, it is possible to sort lightweight and thin members, which could not be sorted by conventional member sorting and supply mechanisms, according to the size of their shape.
It is possible to perform quick sorting in a short time without manual labor. In addition, by simply changing the rotation direction of the drum body, different shape sorting mechanisms operate to sort out members of other types of shapes, and multiple types of members can be sorted with one drum body. Therefore, it is possible to expand the field of use and work efficiency.
