Description

DETAILED DESCRIPTION OF THE INVENTION The present invention distinguishes the size of multiple types of thin plate-shaped members with different shapes, such as pieces of paper, pieces of metal, coins, etc. according to their shapes, and separates the members according to their shapes.
This invention relates to a sorting device that can be selected.

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, if a used ticket is a light, flexible, and easily bendable member that has undergone slight deformation in its shape, forcing it to be ejected from the passageway is likely to 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 out relatively narrow boarding tickets and wider tickets such as coupon tickets due to their differences. Ta.

In view of the above-mentioned drawbacks, the present invention provides a sorting device capable of sorting lightweight and thin-walled members according to their shapes.

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

In this embodiment, a device for sorting rectangular pieces of paper, that is, tickets, according to the shape of the member 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 top 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, FIGS. 3 and 4 explain 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, with one end (the left side in the figure) is wide open, but the other end (the right side in the figure) is closed, and the drive shaft 11 is connected to the center.
1 is connected to a motor 12. Sorting drum 10
is installed so that its axis is horizontal, and support shafts 1 are installed at intervals on the left and right sides of the bottom of the sorting drum 10.
3 and 14 are pivotally supported, and both support shafts 13 and 1
Rollers 15 and 16 are fixed to the left and right sides and the center of 4, respectively, and the rollers 15 and 16 are brought into contact with the outer periphery of the sorting drum 10 to rotatably hold the sorting drum 10. A plurality of sorting mechanisms 17 arranged at equal intervals in a direction parallel to the axial direction of the sorting drum 10 are provided on the outer periphery of the sorting drum 10.
A plurality of rows are formed in the circumferential direction of the sorting drum 10. In the embodiment, four sorting mechanisms 17 are formed in one row, and two adjacent sorting mechanisms 17
are placed close together as a set of two. FIG. 4 is an enlarged view of the two sorting mechanisms 17. Each sorting mechanism 17 punches out the outer periphery of the sorting drum 10, and a thin, elongated band is formed in the punched part. It is formed by gluing plates together. The sorting drum 10 is punched and cut into a slightly trapezoidal shape for each sorting mechanism 17, thereby forming a Mt. Fuji-shaped sliding part 18 and a cannonball-shaped branch part 19 with an acute angle tip. Cage, sliding part 18
is formed in a parabolic shape with both sides approaching each other, and is bent while being inclined outward from the circular outer periphery of the sorting drum 10. An elongated belt-shaped guide plate 20 is fixed to the parabolic cut portion on both sides of each sliding portion 18 over the entire length thereof.
0 will form a shooter of hyperbolic members. That is, one end of the guide plate 20 is located on both sides of the peak of the Mt. Fuji-shaped sliding part 18, and the other end of the guide plate 20 is located at the largest opening of the cut part of the sliding part 18, A rectangular discharge port 2 is formed at one end of the guide plate 20 and the top of the sliding portion 18.
1 is formed, and the lower part of the other end of the guide plate 20 stands up on the inner periphery of the sorting drum 10. The other ends of the guide plates 20 of adjacent sorting mechanisms 17 are connected to form a V-shape so as to surround the branch portion 19. Further, the cross-sectional shape of the formed discharge port 21 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 embodiment, in order to sort tickets A and B of different sizes, the sorting device is set to the state shown in Fig. 1,
When mixed large and small tickets A and B are thrown into the upper opening of the input body 5, the tickets A and B are guided to the chute 8 and stored inside the sorting drum 10 in the main body 1. Once a predetermined amount of tickets A and B have been stored in the sorting drum 10, when the switch on the control panel 4 is turned on, the motor 12 starts and rotates the drive shaft 11, thereby rotating the sorting drum 10 in the direction of arrow U in the figure. . Therefore, the sorting drum 10 rotates with the V-shaped top of the branch 19 of the sorting mechanism 17 as the tip of rotation and the discharge port 21 as the rear end, and the mixed tickets A and B are transferred to the inner peripheral surface of the sorting drum 10 It will be slid and agitated. Therefore, the tickets A and B slide as the sorting drum 10 rotates, and due to their weight they are always located below the sorting drum 10, and when they come into contact with the guide plate 20, they are collected in the direction of the discharge port 21. It turns out. That is, tickets A and B
is the sorting drum 10 regardless of its shape.
Guide plate 20 that slides on the inner peripheral surface and has large openings on the left and right sides
The flow direction is regulated by X, Y, Z in the figure.
The flow is directed towards the center of the guide plate 20. Here, on the adjacent guide plate 20 formed in a V shape, tickets A and B entering from the Y direction are displayed.
is branched at the top of the guide plate 20, distributed to the left and right in the Z direction, and flows toward the center of each sorting mechanism 17. Tickets A and B are always distributed between the pair of guide plates 20. Can be collected. Tickets A and B collected between the guide plates 20 flow through the sliding part 18 and reach the discharge port 21, but the discharge port 21 is pre-formed to a predetermined size and is small in shape. Only the ticket A flows in the direction of the arrow Y, passes through the discharge port 21, and is discharged to the outside of the sorting drum 10. However, since the large ticket B is larger than the cross-sectional shape of the outlet 21, it may get caught on the guide plates 20 on both sides before the outlet 21, or it may flow and be thrown up above the outlet 21. They will remain in the sorting drum 10 without passing through (in this embodiment, the shapes of tickets A and B are set according to the size of their displayed price, and there are two types of shapes. ).

In this way, two types of tickets A with different shapes,
B is separated by the discharge port 21 of the sorting drum 10;
After being sorted, only small-sized tickets A are discharged outside the sorting drum 10, and these tickets A are stored in a collection box 3 provided below the sorting drum 10. Further, the large ticket B remains in the sorting drum 10. When the sorting is completed after a predetermined period of time has elapsed, the drive of the motor 12 is stopped by a timer or the like, the rotation of the sorting drum 10 is stopped, and the collection box 3 is stopped.
Ticket A stored inside by pulling it out towards you
can be transferred to other storage equipment. 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. Ticket B can be taken out from the sorting drum 10 and stored separately from ticket A.

Since the present invention is configured as described above, it is possible to sort only lightweight and thin members of a specific shape according to their shape characteristics, which could not be sorted by conventional parts sorting and supply devices, and it is possible to sort only parts of a specific shape according to the characteristics of the shape. This makes it possible to perform rapid sorting in a short period of time.
