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 paper pieces, metal pieces, coins, etc., according to their shapes, and separates and selects a specific member based on the shape. The present invention relates to a shape sorting mechanism used in a sorting device, and particularly relates to a shape sorting mechanism that is easy to process and assemble.

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 to select from. However, with conventional automatic sorting mechanisms, the sorting mechanism can be constructed relatively easily for heavy and 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 been developed. For example, the sorting of paper pieces such as quintuple tickets, cloth pieces such as offcuts, thin metal pieces, etc. has had to be done manually. For this purpose, a hole with a specific shape is opened on the outer periphery of the sorting drum, which has a hollow cylindrical shape, and only members with a specific shape are released from the hole among the multiple types of materials stored in the sorting drum. A shape sorting mechanism has also been proposed that selects these members (for example, Patent Application No. 61308 of 1982). In this newly proposed shape sorting mechanism, a chevron-shaped cut with a flat top is made on the outer wall of the drum, and the Mt. Fuji-shaped tongue formed by the cut is pushed out slightly to the outside of the drum. A band-shaped guide plate was fitted and fixed, and a rectangular opening was formed by the top of this tongue piece and the left and right guide plates. In this shape sorting mechanism, members are collected in the center by both guide plates, and specific members can be sorted out by passing only those members with a shape smaller than the cross-sectional shape of the opening from among the plurality of members to the outside of the drum. It is something. However, in this structure, it is difficult to fit and fix the guide plate into the notch of the drum, and it cannot be fixed strongly. Also, it is difficult to set a uniform standard for the shape of the opening. It was difficult.

For this reason, it was not possible to assemble and adjust shape sorting mechanisms of the same standard in a short time, and the work had to be done entirely by hand.

In view of the above-mentioned drawbacks, the present invention is easy to process and assemble;
The present invention provides a shape selection mechanism that can form ports with unified specifications.

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

In this embodiment, a member will be explained in which rectangular pieces of paper, that is, regular tickets and common tickets are sorted based on the size of their shapes.

FIG. 1 shows the external appearance of the sorting device of this embodiment. A rectangular main body 1 is connected to a lower part thereof with a similarly rectangular leg body 2. The main body 1 and the legs 2 are connected to each other. are combined together. An insertion opening 3 is opened on one side of the short side of the leg body 2 in a portion corresponding to the majority of the area of the short side.

Further, an input body 9 is connected to the short side of the upper end of the main body 1 by a hinge 8.

The input body 9 has a trapezoidal opening at the top and a triangular shape narrowing downward, and the input port 10 has a large opening on the side closer to the main body 1. A chute 11 that protrudes from the input port 10 into the main body 1 is provided at the lower part thereof in an inclined manner.

Further, FIG. 2 shows a state in which the collection boxes 4 and 5 in FIG. 1 are each pulled out forward and the input body 9 is rotated onto the upper surface of the main body 1 by the hinge 8. A circular opening 12 is formed on the side surface of the main body 1 where the input body 9 is provided, and the opening 12 allows communication between the inside and outside of the main body 1. Sorting drum 13
The open ends of the sides are brought closer together.

Next, FIG. 3 explains this sorting drum 13 in detail. The sorting drum 13 is formed by winding a thin metal material into a pipe shape. The inside is hollow, and one end (-
The medium pressure side) is wide open, but the other end (right side in the figure) is closed and has a drive shaft 14 connected to the center of the other end, and the drive shaft 14 is connected to a motor 15. . The sorting drum 13 is installed so that its axis is horizontal,
At both ends of the sorting drum 13, rollers 16 and 17 are rotatably supported on the main body 1 on the left and right sides of the lower part, respectively.
, 17 are brought into contact with the outer periphery of the sorting drum 13 to rotatably hold the sorting drum 13. On the outer periphery of this sorting drum 13, there are two types of shape sorting mechanisms 18 in the circumferential direction.
．． 19 are arranged in an annular manner at intervals, and in this embodiment, the shape sorting mechanisms 18 are arranged in three annular rows, and the shape sorting mechanisms 19 are arranged in an annular shape so as to be sandwiched between the shape sorting mechanisms 18. There are two columns. Collection guides 20 and 21 in the shape of inverted water droplets are inserted into the outer periphery of the sorting drum 13 alternately at intervals.
They are respectively located on the outer periphery of the shape sorting mechanism 19.

This collection guide 20.21 has a ring portion 2 formed with an opening 22.23 having an inner diameter slightly larger than the outer diameter of the sorting drum 13.
4°25, and a chute portion 26.27 extending below the ring portion 24.25, and the outer circumference has a hollow structure made of a thin sheet metal.

The ring portions 24.25 are each formed into a U-shaped gutter-like cross section near the opening 22.23, and the ring portions 24.25u are shaped like a shape sorting mechanism 18.19 of the sorting drum 13.
They are placed close together, covering each other. The chute portions 26.27 are formed as extension lines of tangents to the respective outer peripheries of the ring portions 24.25, with the negative side facing vertically downward and the other side facing one side. It has a rectangular outlet opening at the bottom. Each chute part 2
The openings at the bottom of each of the holes 6.27 are arranged alternately as shown in FIG. This is where box 5 is placed.

FIG. 5 is an enlarged view of a part of the aforementioned shape sorting mechanisms 18 and 19. Each of the shape sorting mechanisms 18 and 19 forms a cut in the peripheral wall of the sorting drum 13, and a guide body 28 is inserted into the cut. It is assembled by inserting and fixing, and the respective shape selection mechanisms 18 and 19 are arranged so as to face in opposite directions.

FIG. 6 shows an exploded configuration of one shape sorter sis, 19, in which each shape sorting mechanism 18, 19 is connected to a sorting drum 13. Guide body 28. A fixed band 29 is also constructed. The sorting drum 13 is machined with a notch 30 having a width approximately equal to the wall thickness of the guide body 28.
0 consists of three sides: top 31° and sides 32.33. The top portion 31 and the side portions 32 and 33 are each linear, and the top portion 31 is located perpendicular to the rotational direction of the sorting drum 13. One end of each side portion 32 and 33 is connected to both ends of the top portion 31, respectively. In addition, the other ends of each side 32, 33 are open so as to move away from each other.

For this reason, the top portion 31. A trapezoidal notch 30 is formed by the side portions 32 and 33, and a trapezoidal tongue portion 34 is formed in the center left by this notch 30, and the tongue portion 34 is used for sorting. It is slightly bent toward the outside of the drum 13. Next, the guide body 28 is formed by punching out a thin sheet metal using a press or the like. 6. This guide body 28 is formed by a trapezoidal holding plate 35.
A band-shaped sliding plate 3 stands up on the left and right oblique sides of the holding plate 35.
6.37. The holding plate 35 has a trapezoidal shape with the same size as the tongue piece 34, and is pressed so that it has the same radius as the curved radius of the tongue piece 34 so that it can be tightly attached to the tongue piece 34. It is bent near the center. The sliding bodies 36 and 37 are erected at right angles to the oblique side of the holding plate 35, and are in the form of long and narrow strips with the same width, while the two tank moving bodies 36 and 37 are formed in a straight line. and the length jri between the respective adjacent ends of the sliding bodies 36,37
V or W (for the shape selection mechanism 18, W1 and the shape selection mechanism 19, V is the respective set length). The length, width, Y, and width of each are set to be slightly acceptable.

Next, the fixing band 29 is made by bending a long thin sheet metal strip, and is bent into a U-shape so as to have almost the same outline as the top of the guide body 28. are respectively bent outward to form feet 38,39.

To assemble the shape sorting mechanism 18, 19 shown in FIG.
The sliding plates 36 and 37 of the guide body 28 are fitted to the sides [32 and 33 of the notch 3o, respectively]. And fixed band 29
is fitted from the outside of the trapezoidal top of the guide body 28, the center of the fixing band 29 is fixed to the guide body 28, and the leg pieces 38, 3
9 is fixed to the outer periphery of the sorting drum 13. At this time, the separated end surfaces a and b of both tank moving plates 36 and 37 are connected to the sorting drum 13.
It stands on the inner periphery (upper surface in Figure 6) of both tanks moving plate 36.
The close end surfaces c and d of 37 protrude from the outer periphery of the sorting drum 13 (lower surface in FIG. 6), thereby allowing the sliding plate 36.3
7 has an inclined angle with respect to the inner peripheral surface of the f/li sorting drum 13. On both sides of the tongue piece 34, sliding plates 36 and 37 stand up at right angles to form a trapezoidal chute. A rectangular outlet 40, 41 is formed by the edges c, d and the top 31, and the width of the outlet 400 is W, and the width of the outlet 41 is V. The ring portion 24.25 of the collection guide 20.21 is positioned on the outer periphery of each shape sorting mechanism 18.19 and is held by a support means separate from the sorting drum 13.

Next, the operation of this embodiment will be explained.

In this embodiment, as shown in FIG. 7, a case will be explained in which common tickets A and regular tickets B of different sizes are sorted. The widths are set to X and Y, respectively. First, in order to select common coupon tickets A, the sorting device is set to the state shown in FIG. 1, and the common coupon tickets A are mixed together.

When the regular ticket B is inserted into the upper opening of the input body 9, both tickets are stored inside the sorting drum 13 in the main body l guided by the chute 11. Once a predetermined amount of common tickets A and ordinary tickets Be have been stored in the sorting drum 13, when the switch on the control panel 7 is turned on, the motor 15 starts, rotates the drive shaft 14, and moves the sorting drum 13 in the direction indicated by the arrow in the figure. Rotate in direction F. For this reason, the sorting drum 13 is the shape sorting mechanism 1.
The enlarged ends a and b of the sliding plates 36 and 37 of 9 are the tips of rotation, and the discharge port 41f is the rear end. This results in sliding and stirring on the inner peripheral surface of the sorting drum 13. For this reason, the common ticket A and the regular ticket B are slid by the sorting drum 130 rotations, and due to their weight, the sorting drum 13 is always
It is located below and is scraped in the direction of the discharge port 41 by contacting the sliding plates 36 and 37. In other words, the common ticket A and the regular ticket B slide on the inner circumferential surface of the sorting drum 13 regardless of their shape, and their flow direction is regulated by the two-tank moving plates 36 and 37 that have large openings on the left and right. The flow is directed towards the gradually narrowed center of both tank moving plates 36,37. In this way, the common ticket A and the regular ticket B flow toward the center of each shape sorting mechanism 19, and both of them are necessarily connected to the pair of sliding plates 36.3.
Collected between 7. The common ticket A and the regular ticket 9B collected between the sliding plates 36 and 37 flow on the tongue piece 34 and flow to the discharge port 41, but the discharge port 41 has a predetermined length V. Only the common ticket A having a small shape passes through the discharge port 41 and is discharged to the outside of the sorting drum 13. However, since the regular ticket B, which is larger in shape than the common ticket A, is larger than the cross-sectional shape of the outlet 41, it either gets caught on the sliding plates 36 and 37 on both sides before the outlet 41, or flows into the outlet 41. Since it is thrown upward, it remains in the sorting drum 13 without passing through the discharge port 41. The common coupon A discharged from the discharge port 41 on the outer periphery of the sorting drum 13 is collected by the ring portion 25 of the collection guide 2.
The water enters the space having a U-shaped cross section, slides on the inner circumferential surface of the ring part 25, falls, flows into the chute part 27, and due to its own weight passes through the outlet opened at the bottom of the chute part 27 and collects the collection box 4.
It will fall and be collected.

Next, the sorting drum 13 is rotated in the direction of arrow F for a predetermined period of time, and when all the common tickets A are ejected and ordinary tickets B remain, the driving of the motor 15 is stopped by a KrI'i timer or the like, and further The control panel 7 is operated to drive the motor 15 in the reverse direction, and the sorting drum 13 is reversely rotated in the direction of arrow G, so that the ordinary ticket B is slid and stirred within the sorting drum 13. Therefore, the regular ticket B flows toward the center of the shape sorting mechanism 18 in the same manner as described above, and the regular ticket B is collected between the pair of sliding plates 36 and 37.
is discharged to the outside of the sorting drum 13 through the discharge port 40, enters the space of the U-shaped cross section of the ring portion 24 of the recovery guide 2o, slides on the inner peripheral surface of the ring portion 24, and flows into the chute portion 26. Then, due to its own weight, it falls into the collection box 5 (through the discharge port opened at the bottom of the chute section 26) and is collected therein.

In this way, only the common ticket A is collected separately in the collection box 4, and only the regular ticket B is collected in the collection box 5, and they are stored separately.

By rotating the sorting drum 13 in this manner, the common ticket A and the ordinary ticket B are sorted and separated.

After driving the motor 15 for a predetermined period of time, the drive of the morph 15 is stopped using a timer or the like, and the rotation of the sorting drum 13 is stopped. Items that cannot be sorted, such as scrap paper bills and defective tickets, will remain.

After completing this series of sorting operations, the equipment must be cleaned in order to perform the next sorting operation. first,
Pull out collection boxes 4 and 5 toward you, and remove each collection box 4.5.
Transfer the common ticket A and regular ticket B stored in the storage device to separate storage devices, manage the common ticket A and regular ticket B separately, and dispose of them by incinerating or cutting them at a predetermined time. conduct. Then, as shown in FIG. 2, the input body 9 is rotated upward about the hinge 8 to expose the opening 12, and the user can either insert a hand into the sorting drum 13 through the opening 12, or use a vacuum suction machine. Components that cannot be sorted using the sorting drum 13 can be taken out from the sorting drum 13 and stored separately from the common ticket A and the ordinary ticket B. Then, by inserting the collection boxes 4 and 5 into the apparatus and rotating the input body 9 around the hinge 8 to return to the state shown in Fig. 1, preparations can be made for the next sorting operation. .

Since the present invention is configured as described above, the shape sorting mechanism can be assembled by simply fitting the guide body into the notch of the sorting drum, and there is no need to adjust the shape, which speeds up the assembly work. , standards can be easily unified.
