DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

According to the present invention, a large number of used magazines X are separated one by one by a separating section consisting of a plurality of roller groups A and supplied to a sorting conveyor B, and the magazine is attached to a magazine by a recognition section 1 provided in this sorting conveyor B. The identified identification code 2 is identified and sorted, and the tray b of the sorting conveyor B at a predetermined position is opened and sorted and collected based on the identified sorting signal. A so-called two-story structure in which a sorting conveyor B is installed in the lower stage, the separating section arranges star-shaped rotating rollers a in a line at a predetermined interval, and the rollers in the next line are arranged in the interval. This is repeated alternately several times so as to be arranged in the same manner as in the previous row during that interval and in the same manner as in the previous row during that interval, and alternately arranged in several rows a ₁ to ₇ Forming one roller group A A plurality of the roller groups A are provided as a separating section, and trays b for accommodating magazines supplied one by one from the separating sections are connected endlessly to form a sorting conveyor B, and the sorting conveyor B is predetermined. Is a device provided with a recognizing unit 1 at the position of, and a pusher for opening the bottom 3 of a predetermined tray b on the basis of the classification signal identified by the recognizing unit 1. ,
The staggered shape arranged in sequence a ₁ ~ ₇ alternately Star-rotating rollers staggered shaped column are rotational speeds are the same,
The rotation speed of the next staggered row is made faster in the previous staggered row and the next staggered row.

The separating unit separates a large number of used magazines X collected one by one and supplies them to the sorting conveyor B, and collects a certain number of the large number of magazines X accumulated in the hopper 4. It is sent to the first roller group A1 by the push-up bar 5, separated through the plurality of roller groups A, and reliably fed one by one from the final roller group A3 to the connecting hopper 6, and from the connecting hopper 6 to the next sorting conveyor B. Then, the trays of the sorting conveyor B are surely supplied one by one by dropping them at the same timing.

In the drawing, a conveyor belt conveyor A "is provided in front of the first roller group A1 and a certain number of pieces are separated into a large amount and sent to the first roller group A1. However, at this stage, they are still in an overlapping state. , The first roller group A1 is further separated from the overlapped state and transferred to the second roller group A2 and the third roller group A3, and the roller group A has a three-stage configuration so as to be further surely separated one by one. However, it is optional that the conveyor belt conveyor A ″ is not provided or, instead, a roller group similar to other roller groups has a two-stage configuration or a four-stage configuration or more. The more or the longer the configuration of the roller group A is, the smaller the probability that two or more rollers are overlapped and fall and the one group can be surely supplied to the connecting hopper 6.

Further, between the hopper 4 and the conveyor belt conveyor A "or the first roller group A1, between the conveyor belt conveyor A" and the first roller group A1, between the roller groups, and the third roller. A slide plate is interposed between the group A3 and the connection hopper 6 to facilitate the sequential transfer, and a sensor 8 for operating the drive source 7 is provided at each of the intervals according to the status of the transfer. .

In the roller group A, the star-shaped rotating rollers a are arranged in a row a ₁ at a predetermined interval, the rollers in the next row a ₂ are arranged in that interval, and then the front row is arranged in that interval. a
_The array a ₃ is the same as that of _1, and the previous row a
_{As in the case of 2} , the arrangement is repeated a number of times in a staggered manner so as to be arranged a ₄ and alternately arranged in several rows (7 rows in the figure, but not limited to this) to form one roller group A. The magazines of all shapes are separated one by one, and the rollers of the first staggered rows a ₁ and a ₂ (first and second roller rows) are rotated at the same speed, and the next staggered rows a ₁ and a ₂ are rotated. The rollers of ₃ , a ₄ (third and fourth roller rows) should be rotated slightly faster than the rollers of the alternating rows a ₁ , a ₂ (first and second roller rows) of the front row, and the next row a Similarly, after ₅ , a ₆ (fifth and sixth roller rows), the forward feeding of the magazine X is promoted by the peripheral speed difference of the so-called rotating roller a so that the magazine X is separated one by one. . The peripheral speed difference, that is, the rotation speed, can be increased by separating the rear row by 1.1 to 2.5 times faster than the front row.

Any means can be selected as means for imparting a peripheral speed difference to the rotating rollers. In the illustrated embodiment, a small diameter pulley and a large diameter pulley are attached to the rotating shaft of each roller row, and The belt is stretched over the small diameter pulley and the large diameter pulley of each roller row before and after the odd number rows and even number rows, and on one side, seven rows of small diameter pulleys and five rows of large diameter pulleys, five rows Row small diameter pulley and three rows large diameter pulley, three rows small diameter pulley and one row large diameter pulley, on the other side six rows small diameter pulley and four rows large diameter pulley, four rows small diameter pulley and two rows large Each of them is hung on a diameter pulley, and is driven by seven and six rows of rotating shafts.

The star-shaped rotary roller a is designed so as to separate and feed a large number of mixed and overlapping magazines of any shape, rather than a simple circular (cylindrical) shape or convex-concave convex-concave shape. As shown in the drawing, the side (or cross section) is star-shaped like a star, and the tip of the convex part is tapered to a narrow width, and not a plate (thin material) but a certain width (length). It is preferable that the roll-like shape has a plurality of convex portions for feeding or separating. In this case, it is optional to form the same body of rubber or synthetic resin such as ultra-high molecular weight polyethylene resin or polyacetal resin, or to integrally form the above-mentioned shape by combining using a metal steel plate. Also, damage to the magazine,
In terms of feed stability, adhesion (bite), elasticity, etc., the hardness of the roller is also taken into consideration depending on the material of this roller. Shore hardness 66 for rubber, type of resin for synthetic resin Rockwell hardness 52 for polyethylene resin, Rockwell hardness 118 for polyacetal resin, HRB for metal steel sheet
A hardness of about 79 is preferable.

Each of the plurality of roller groups A has an independent drive source 7, but they are not driven and stopped separately but are driven together. However, each drive source is driven intermittently by the action of the sensor 8, that is, depending on the feeding condition from one roller group to the next roller group, and each drive source 7 is connected to the pulley 9 in any row, and the same roller group is connected. In (1), even-numbered rows and odd-numbered rows are connected to the respective rollers a so as to have a peripheral speed difference.

The magazines X separated from the third (final) roller group A3 one by one are supplied to the connection hopper 6 one by one and dropped onto the tray b of the sorting conveyor B at a timing. The sensor 8 catches this falling situation and drives the roller groups A and the push-up rods 5 of the hopper intermittently. When supplying from the final roller group A3 to the connection hopper 6, a bending guide portion 10 is formed in the connection hopper 6 to drop the horizontally supplied magazine in accordance with the inclination of the tray b, and continuously rotate at a good timing. It is appropriately dropped on the incoming tray b. At this time, a receiving plate (not shown) may be provided below the connecting hopper 6 so that the magazine does not drop directly onto the tray, and the receiving plate may be temporarily received and the receiving plate may be opened at the above timing.

The hopper 4 has a large number of collected magazines X.
Is a part for sending out to the conveyor belt conveyor (or the first roller group) A1 for transporting while accumulating and accumulating, and the hopper is provided with a push-up bar 5 which moves up and down by a cylinder to form a magazine in the hopper to some extent. Try to push up the quantity collectively. In the case where the hopper is located at a high place due to the two-story structure as shown in the figure, it is possible to move the hopper itself up and down to facilitate the stacking work of the magazines.

The sorting conveyor B is the last roller group A3
In order to sort and sort the magazines X which are surely separated into one by one and supplied through the connection hopper 6, trays b for accommodating the magazines one by one are connected and formed in the form of an endless conveyor. The recognizing unit 1 is provided at a predetermined position of the sorting conveyor B, preferably at a position immediately after being supplied and stored, and the pusher 11 which opens the bottom 3 of the predetermined tray b based on the sorting signal identified by the recognizing unit 1 is provided. Are provided at a predetermined number of appropriate intervals, and the recovery boxes 12 are installed at the positions of the trays b to be opened. In this case, the sorting conveyor B is installed so that the tray b is inclined as shown in FIG. 3, so that the accommodated magazine is always located at one end of the tray b, and the tray 3 is inclined after the bottom 3 is opened. It is made to fall to the collection box 12 along.

The recognition unit 1 recognizes and identifies the identification code 2 (characters, symbols, numbers, etc.) shown in the magazine X stored in the tray b, and corresponds to the identification code after being stored in the tray b. A plurality of cameras are installed at the positions so that the identification code can be recognized from each surface. This can be done by selecting the number and position of cameras installed depending on whether the magazine X is made of a transparent material or an opaque material, or the number of printed identification codes and the printing location. In the drawing, assuming that the magazine X is made of a transparent material, two cameras of the recognition unit are installed as a case of a method of reading with either the front or back (mirror) character of the identification code. This camera recognizes the identification code 2 and transmits the identified classification signal to a predetermined pusher 11, and when the tray b reaches a predetermined position, the pusher 11 operates to move the bottom 3 of the predetermined tray b. The magazine X is pushed and opened to drop the magazine X from the tray b by this opening, and the collection box 12
To be stored in.

The tray b has a flat and slender shape, and the bottom portion 3 is openable / closable. When the tray 3 is installed in an inclined shape, a transparent hole 14 is formed in the bottom portion and the side portion on one end side, and the camera (recognition portion) is provided.
A magnet 15 is attached to the other end to enable the identification by 1 and to close and rotate the bottom portion 3 opened by the pusher 11. A large number of trays b formed in this way are connected to the chain 16 at an appropriate interval in an endless conveyor form, and are installed in a slanted manner with a slope for aligning one end side of the magazine, and the tray itself is also provided with a magazine. A slope is provided so that the side of the tray contacts one side of the tray. As shown in FIG. 4, the bottom 3 of the tray b is opened by the pusher 11 operated by the classification signal identified by the camera 1, the magazine is dropped, and the bottom 3 is moved to the upper side of the tray after making a forward U-turn with the magazine open. It will be located and will return by its own weight, and the open state will be closed. At this time, even if the magnet 15 attracts the U-turn again, the bottom portion 3
Does not open under its own weight.

The pusher 11 identifies the identification code 2 of the magazine in the tray b by the camera 1 and operates according to a predetermined classification signal. The classification signal moves the air cylinder to push and open the bottom portion 3 of the tray b. . This pusher 11 is installed in accordance with the number to be classified, but an extra one is provided so that the pusher 11 which is not suitable for classification or the one whose recognition is poor can be classified.

The recovery box 12 accommodates a magazine in which the bottom 3 of the tray b is opened and drops.
The guide plate 17 and the partition plate 18 which are installed depending on the position of the falling edge while being inclined and fall are attached to the inclined side of the sorting conveyor B, so that mixing upon falling can be prevented.

In the above embodiment, the separating section is provided on the upper stage and the sorting conveyor B is installed on the lower stage, which is a so-called two-story structure. However, as shown in FIG. 9, the sorting conveyor B is provided on the upper stage and the separating section is provided on the lower stage. Alternatively, the collection box 12 may be installed directly below the sorting conveyor B. Further, although not shown, it is optional to install the collection boxes 12 in parallel without forming a two-story structure. Further, although the tray b of the sorting conveyor B is installed in an inclined shape, when the magazine is stored in the tray b, the magazine 1 can be recognized by the camera 1 at one end side, for example, the transparent hole 14 side. In such a state, it may be installed in a plane rather than in an inclined shape. It is also possible to provide a milky white plastic plate in the see-through hole 14 so that the magazine does not drop from this hole.

As described above, according to the present invention, a large number of magazines are separated one by one by a separating section composed of a plurality of rollers and supplied to a sorting conveyor, and the magazine is attached to the magazine by a recognition section provided in this sorting conveyor. The star-shaped rotary rollers are arranged in a line at a predetermined interval so that the sorting conveyors can be sorted and recovered by opening the sorting conveyor at a predetermined position based on the identified sorting signal. Arrange the rollers in the next row during the interval, and also arrange them in the same manner as one row in the interval, and repeat this several rows alternately to form one roller group, and provide this roller group multiple times. To form a sorting section, and endlessly connect the trays supplied and stored from the separating section endlessly to form a classification conveyor, and a recognition section is provided at a predetermined position of the classification conveyor, and the recognition section identifies It It is equipped with a pusher that opens the bottom of a specified tray based on the classification signal, so that used magazines are automatically sorted (sorted) by manufacturer, material, or shape.
