Description

DETAILED DESCRIPTION OF THE INVENTION 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 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 easily configure a sorting body that has a function of sorting members, and can facilitate manufacturing and assembly.

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 that has a certain gate in the upper bowl and removes irregularly shaped parts from the bowl depending on whether or not they can pass, or a bowl-shaped parts feeder that feeds parts on a straight track. A mechanism that detects drops by the size of the shape by conveying them with a belt, or by swinging a horizontal plate provided with a drop port, and a mechanism in which a drum with a port corresponding to the thickness of the flake sorting member is placed vertically. A feeder or the like has been devised in which a specific member is discharged by centrifugal force by placing it facing the object and rotating it at high speed. However, for parts like used tickets that are light, flexible, and easy to bend, and whose shape has slightly deformed, attempting to forcefully eject them from the exit can easily cause damage or breakage. In addition, large deformations were caused, rather than the fine local deformations that are typical of tickets after use. 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 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 shape sorting device has been proposed that can sort ticket pieces by discharging only ticket pieces of a specific shape from an opening (for example, a patent application published in Showa
57 No. 61308, etc.). However, in this newly proposed sorting device, the inner diameter of the sorting drum is large, making it difficult to process into a cylindrical shape, making manufacturing and assembly complicated, and increasing the price. In particular, the discharge port provided on the outer periphery of the sorting drum for discharging the members must be precisely formed, and higher manufacturing precision is required compared to the size of the inner diameter of the sorting drum.

In view of the above-mentioned drawbacks, the present invention consists of a drum-shaped sorting body having a sorting function, which is composed of a plurality of sorting elements, and the adjacent sides of these sorting elements are overlapped to form a cylindrical shape. The present invention provides a sorting device that is simple and easy to assemble.

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 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 body 10 housed therein are brought close to each other.

Next, FIG. 3 shows a detailed explanation of the sorting body 10. Each sorting body 10 is composed of one retaining ring 11, one driving cup 12, and a plurality of plates 13 as sorting elements. The retaining ring 11 is made of a thin steel plate bent into an annular shape with large openings on both sides, and the drive cup 12 is similarly made of a thin steel plate with one end face of the ring formed by bending it into an annular shape closed and a shallow opening formed. It is plate-shaped,
The inner and outer diameters of the retaining ring 11 and the drive cup 12 are the same. Next, the plate 13 is formed by pressing a thin steel plate, and has an elongated shape with predetermined parts punched out. The retaining ring 11 and the driving cup 12 are spaced apart so that their axes coincide, and a plurality of plates 13 are disposed between the respective outer peripheral edges of the retaining ring 11 and the driving cup 12 in the longitudinal direction. Each plate 13 is connected to a retaining ring 11 and a drive cup 12 by screws 14 at both ends thereof.
Each plate 13 is arranged around the outer periphery of the retaining ring 11 and the drive cup 12 such that each plate 13 overlaps the other adjacent plate 13 little by little so that there is no gap. Therefore, the holding ring 11, the drive cup 12, and the plurality of plates 13 form a drum-shaped sorting body 10 with one end open. This sorting body 10 is installed so that its axis is horizontal, and support shafts 15, 16, and 1
7 is pivotally supported, and each support shaft 15, 16, 1
Rollers 18, 19, 20 are fixed on the left and right sides of the cup 7, respectively, and the rollers 18, 19, 20 are brought into contact with the outer circumferences of the retaining ring 11 and the drive cup 12, respectively, and the rollers 18, 19, 20 sort the cups. The body 10 is held rotatably. Further, a drive shaft 21 is connected to the center of the side surface of the drive cup 12, and a motor 22 is connected to the drive shaft 21.

Next, FIG. 4 explains the above-mentioned plates 13 in detail. Each plate 13 has a pair of mounting holes 23 opened at intervals on the short sides thereof, and one long side of each plate 13. The weight portion 24 is formed by shallowly bending in a dogleg shape along its length. The area from the other long side of each plate 13 to the vicinity of the center is drawn by a press, and a sliding portion 25 as a recess and a separation portion 27 as a convex portion are formed. The sliding part 25 has a trapezoidal shape with its top aligned with the other long side, and the separation part 27 has a triangular shape with one side aligned with the other long side. part 25 is 4
The separating portions 27 are formed at three locations located between the sliding portions 25.
and the sides of the separation part 27 are connected by a sharp triangular side wall part 26 positioned vertically. The above-mentioned sliding part 25 has its parallel short side located on the other side of the plate 13 (the long side opposite to the overlapping part 24), and the truncated part of the sliding part 25 and A U-shaped discharge port 28 is formed on the other side of the plate 13 by the shortest side of the side wall portion 26.
The width W of the discharge port 28 is set to a predetermined length in advance. The plane portion of the sliding portion 25 is inclined from the trapezoidal truncated head toward the bottom, and the bottom portion is formed into a gentle slope at the same height as the top surface of the plate 13. . Furthermore, the upper surface of the triangular separation part 27 is connected to the plate 1.
It is located at the same height as the top surface of 3. One plate 13 is formed by press working as described above, and in order to connect a plurality of plates 13 and secure them to the retaining ring 11 and drive cup 12, as shown in FIG. The matching plates 13 are slightly overlapped, and each plate 13
The elongated overlapping portion 24 is brought into close contact with the upper surface of the other plate 13, and a U-shaped discharge port 28 is formed as a rectangular opening. Therefore, most of the upper surface of each sliding portion 25 is exposed toward the internal space of the sorting body 10, except for a portion covered by the overlapping portion 24.

Next, the operation of this embodiment will be explained.

In this embodiment, a case will be explained in which tickets A and B of different sizes and sizes are sorted. The length X of the short side of this ticket A is slightly shorter than the width W of the discharge port 28,
The length Y of the short side of the ticket B is longer than the width W of the outlet 28.

First, to select small tickets A, set the sorting device to the state shown in Fig. 1, and insert the mixed large and small tickets A and B from the upper opening of the input unit 5, and the tickets A and B will be placed in the chute 8. It is guided and stored inside the sorting body 10 in the main body 1. Once a predetermined amount of tickets A and B have been stored in the sorting body 10, when the switch on the control panel 4 is turned on, the motor 22 starts and rotates the drive shaft 21, thereby rotating the sorting body 10 in the direction of arrow F in the figure. . For this reason, the holding ring 11, drive cup 12, and multiple plates 13 that constitute the sorting body 10 are rotated simultaneously, and the plates 1
3 rotates with the vertex of the triangular separating portion 27 as the tip of rotation, and the long side of the trapezoidal sliding portion 25 as the tip of rotation. Therefore, the mixed tickets A and B are slid and stirred on the inner peripheral surface of the sorting body 10, and the tickets A and B are slid by the rotation of the sorting body 10 and are constantly sorted by their weight. It is located below the body 10 and is collected in the direction of the discharge port 28 by the sliding part 25 and the side wall part 26. That is, the tickets A and B slide on the inner circumferential surface of the sorting body 10 regardless of the size of their shape, and the direction of flow is regulated by the side wall portion 26 that has large openings on the left and right, and the flow is directed through the narrow center of the side wall portion 26. Directed in direction. This side wall portion 26
Tickets A and B collected during this period flow through the sliding part 25 and flow to the discharge port 28.
has its width W set in advance to a predetermined size,
Only the small-sized tickets A pass through the discharge port 28 and are discharged to the outside of the sorting body 10. However, since the ticket B, which is larger in shape than the ticket A, is larger than the opening shape of the discharge port 28, it either gets caught on the side walls 26 on both sides before the discharge port 28, or flows and is thrown up above the discharge port 28, so that it is not discharged. It will remain in the sorting body 10 without passing through the outlet 28. Rotate the sorting body 10 in the direction of arrow F for a predetermined period of time to sort small tickets A.
When all the tickets have been discharged, the drive of the motor 22 is stopped using a timer or the like, the collection box 3 is pulled out to the front, the tickets A are stored in another box, the collection box 3 is emptied, and then the collection box 3 is emptied. Insert and set at the bottom of main body 1. Since ticket B remains in the sorting body 10, the next sorting operation cannot be performed unless this ticket B is collected. First, the input body 5 is rotated about the hinge 6 as shown in FIG. 2 to expose the opening 9, and the user inserts a hand into the sorting body 10 through the opening 9 or uses a vacuum suction machine. Tickets B can be taken out from the sorter 10 and stored separately from tickets A (in this embodiment, the shapes of tickets A and B are set according to their displayed prices). ).

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 conventionally, in a short time and quickly without manual labor. It is possible to carry out a thorough selection. A sorting body with a sorting function can be composed of multiple sorting elements, and each sorting element can be manufactured extremely easily and with high precision by press processing, etc., compared to manufacturing and assembling a single large-diameter sorting drum. The work is easy and inexpensive.
