That is, according to the detected waste material, the controller 195 rotates the distribution rotor 141 to connect the outlet of the corresponding distribution groove 1412 to a specific waste transport track among the waste transport tracks 137a, 137b, and 137c. By doing so, it is possible to send the waste (W) to a waste transport track suitable for the material. In this embodiment, it is illustrated that four distribution grooves 1412 are formed, but the number of distribution grooves 1412 is preferably three or more. However, it should be noted that the number of distribution grooves 1412 does not limit the present invention.

Hereinafter, with reference to FIGS. 3 and 8 to 13 , a process of distributing and sorting waste using the waste distributor 140 in the waste sorting unit 127 will be exemplarily described.

For example, after several wastes are input to the waste input unit 107, glass waste (Wg) among various types of waste rises in a state separated from other wastes by the ascending transfer unit 109, and then As a result, the free waste (Wg) is arranged in a state in which it can be transported by the input transport unit 110 through the alignment unit 106 and can be rotated by the waste rotation unit 114 . In this aligned state, the waste detector 121 detects glass waste Wg and transmits a detection signal to the controller 195 . Next, by the input transfer unit 110, the glass waste (Wg) moves to the distribution groove 1412 of the waste distributor 140, the control unit 195, as shown in FIG. Rotate the dispensing rotor 141 of the waste dispenser 140 so that the dispensing groove 1412 is at a position facing (ie, connecting to) the glass waste conveying track 137b. When the position of the distribution groove 1412 receiving the glass waste (Wg) in the input transfer unit 110 is the same as the position facing the glass waste transfer track 137b, the distribution rotor 141 is maintained without rotating it. can In this state, the glass waste Wg is transferred onto the sorting conveyor 128, and as the sorting conveyor 128 moves, the glass waste Wg follows the glass waste transport track 137b to the glass waste collector ( 147b). Glass waste (Wg) may be moved from the distribution groove 1412 to the sorting conveyor 128 by the transfer force (or inertia) applied from the input transfer unit 110, but if the transfer force is not sufficient, It may also be considered to have a gradient in the distribution groove 1412 .

In addition, after several wastes are input to the waste input unit 107 , the plastic waste Wp among the various types of waste rises to a state separated from other wastes by the ascending transfer unit 109 , and then The plastic waste Wp is arranged in a state in which it can be transported by the input transport unit 110 through the alignment unit 106 and can be rotated by the waste rotation unit 114 . In this aligned state, the waste detector 121 detects the plastic waste Wp and transmits a detection signal to the controller 195 . Next, the plastic waste (Wp) is moved to the distribution groove (1412) of the waste distributor (140) by the input transfer unit (110), the control unit (195) as shown in FIG. The distribution rotor 141 of the waste distributor 140 is rotated so that the distribution groove 1412 is placed at a position facing (ie, connecting position) the plastic waste conveying track 137a. In this state, the plastic waste Wp is transferred onto the sorting conveyor 128, and as the sorting conveyor 128 moves, the plastic waste Wp follows the plastic waste transport track 137a to the plastic waste collector ( 147a) can be transferred to the side. The plastic waste Wp may be moved from the distribution groove 1412 onto the sorting conveyor 128 by the transfer force (or inertia) applied from the input transfer unit 110, but if the transfer force is not sufficient, It may also be considered to have a gradient in the distribution groove 1412 .

In addition, after several wastes are put into the waste input unit 107, metal waste Wm among various types of waste rises in a state separated from other wastes by the ascending transfer unit 109, and then The metal waste Wm is arranged in a state in which it can be transported by the input transport unit 110 through the alignment unit 106 and can be rotated by the waste rotation unit 114 . In this aligned state, the waste detector 121 detects the metal waste Wm and transmits a detection signal to the controller 195 . Next, the metal waste Wm by the input transfer unit 110 moves to the distribution groove 1412 of the waste distributor 140, and the control unit 195 receives the metal waste Wm as shown in FIG. 13 . The distribution rotor 141 of the waste distributor 140 is rotated so that the distribution groove 1412 is placed at a position facing (ie, connecting position) the metal waste conveying track 137c. In this state, the metal waste Wm is transferred onto the sorting conveyor 128, and as the sorting conveyor 128 moves, the metal waste Wm follows the metal waste transport track 137c to the metal waste collector ( 147c). The metal waste Wm may be moved from the distribution groove 1412 to the sorting conveyor 128 by the transfer force (or inertia) applied from the input transfer unit 110, but if the transfer force is not sufficient, It may also be considered to have a gradient in the distribution groove 1412 .

The label discharge guide 171 includes a label transport path 172 connected to the label suction port 155 of the casing 151 to transport the label discharged from the label removal chamber 152, and a label transport path 172. The label outlet 173 connected to the label transfer path 172 to discharge the label to the label collection unit 146f, and the label transfer path 172 to discharge the air of the label transfer path 172. An air intake 174 is provided. A sieve 175 is disposed at the air intake 174 . The sieve 175 may filter the label by being provided with a plurality of through holes of a size that the air passes through but the label cannot pass through. Labels flowing from the label removal chamber 152 of the casing 151 into the label transport path 172 through the label suction port 155 are transported along the label transport path 172 and pass through the label outlet 173 to the label collection unit (146f).

The suction force generating unit 177 is connected to the air suction port 174 so that the air of the label transfer path 172 can be forcibly discharged through the air suction port 174 . The suction force generated by the suction force generating unit 177 acts on the label suction port 155 through the air suction port 174 and the label transfer path 172 . Accordingly, the label separated from the plastic waste (Wp) in the label removal chamber 152 of the casing 151 may be sucked into the label transfer path 172 through the label suction port 155 .

The label transfer conveyor 178 transfers the label sucked into the label transfer path 172 through the label inlet 155 toward the label outlet 173 . The label transfer conveyor 178 is disposed on the label transfer path 172 and includes a label transfer unit 179 for forcibly transferring the label toward the label outlet 173 . The label transfer unit 179 includes a transfer screw 180 . The transfer screw 180 includes a label transfer rotation shaft 181 disposed in the longitudinal direction of the label transfer path 172, and a label transfer spiral guide 182 spirally provided on the outer circumferential surface of the label transfer rotation shaft 181, It extends from the label inlet 155 to the label outlet 173 side.

As the transfer screw 180 rotates, the label sucked into the label transfer path 172 may be forcibly transferred to the label outlet 173 along the label transfer spiral guide 182 of the transfer screw 180 .

If the suction force generated by the suction force generating unit 177 strongly acts even on the label outlet 173 , there may be a problem that the label is not smoothly discharged from the label outlet 173 . In order to prevent this problem, the label inhaler 170 takes a structure in which the suction force does not act as much as possible at the label outlet 173 . That is, in the label transport path 172 of the label inhaler 170 , the width Wc2 at the portion connected to the label outlet 173 is reduced than the width Wc1 at the portion connected to the air intake 174 . , and a predetermined section from the middle part of the label transport path 172 to the part connected to the label outlet 173 has a size somewhat larger than the width of the transport screw 180 . If the label transport path 172 is in this form, the interference between the label ejection guide 171 and the transport screw 180 in the downstream part from the middle part of the label transport path 172 to the part connected to the label outlet 173 is reduced. It is possible to increase the air resistance by the transfer screw 180 while avoiding it. In this way, in the downstream part of the label transfer path 172 , the transfer screw 180 obstructs the air flow, so that the suction force of the suction force generating unit 177 is weakly applied, and the label is transferred to the label outlet 173 by the transfer screw 180 . It can be transferred smoothly to the side.

The label remover 150 is controlled by the control unit 195 and can operate for a certain time when the plastic waste (Wp) is input through the waste input unit 107, and separates the plastic waste (Wp) and the label, respectively. It can be discharged toward the plastic waste collection unit 146a and the label collection unit 146f.

In addition, the label remover 150 uses a method in which the striking body 160 first separates the label, the rotary blade 167 separates the label secondary, and sucks the label with the label aspirator 170 . Wp) can be efficiently separated from the label.

As shown in FIG. 15 , the striking body 160 moves in a substantially vertical direction with respect to the longitudinal direction of the rotating shaft 157 while rotating in association with the rotation of the rotating shaft 157 , thereby the striking body 160 and the casing 151 . The plastic waste Wp placed therebetween is strongly struck toward the inner surface of the casing 151 . Accordingly, the plastic waste Wp is transferred to the portion where the rotary blade 167 is disposed in a state in which the volume is reduced by the striking body 160 .

In the portion where the rotary blade 167 is disposed, the label attached to the plastic waste Wp is secondarily separated by the action of the rotary blade 167 and the fixed blade 156 . And the label-removed plastic waste (Wp) is smoothly collected to the plastic waste collection unit 146a through the plastic waste outlet 154 under the action of the discharge pressure blade 168, and the label separated from the plastic waste Wp Silver is collected by the label collecting unit 146f by the suction force generated by the suction force generating unit 177 of the label aspirator 170 and the conveying force by the label conveying conveyor 178 .

The specific structures of the label discharge guide 171 provided in the label aspirator 170 , the suction force generator 177 , and the label transfer conveyor 178 are not limited to those shown and may be variously changed.
