[0042] Please refer to Figure 1 , the embodiments of the present invention provide a card collating machine 100, including a collection unit 110, a collation unit 120, a transmission unit 130, a detection unit 140, and a recycling unit 150. The collection unit 110 is used to receive cards. The collation unit 120 is used to convey the received cards to the transmission unit 130 in sequence. The transmission unit 130 is used to transmit the cards output by the collation unit 120 to the detection unit 140. The detection unit 140 is used to read and write information on the cards and convey the cards after the reading and writing is completed to the recycling unit 150.

[0043] The above-mentioned card collator 100 can automatically count the access cards. As long as about 300 access cards are poured into the collection unit 110 of the card collator 100 at one time, the card collator 100 will automatically separate the access cards one by one, flow into the detection unit 140, complete the information processing, and finally stack the access cards neatly to achieve rapid counting of the access cards. The above-mentioned card collator 100 has the advantages of high efficiency, no need for manual intervention, and can realize rapid allocation of access cards, etc.

[0044] As required, the card collator 100 further includes a power supply 180, a main control board 181, and a speed regulator 182. The power supply 180 supplies power to the entire device. The main control board 181 is used to control various electrical devices in the card collator 100. The speed regulator 182 is used to control the movement speed of the conveyor belts in the sorting unit 120 and the transmission unit 130. As required, universal wheels 183 can also be provided on the four feet of the card collator 100 to facilitate the movement of the card collator 100.

[0045] Please refer to Figures 2 to 4, the collecting unit 110 includes a card loading box 111, and the sorting unit 120 includes a bracket 121 and a first conveyor belt 122 disposed on the bracket 121. An ejection opening 123 is provided between the upper surface of the card loading box 111 and the upper surface of the first conveyor belt 122. The upper surface of the first conveyor belt 122 moves toward the ejection opening 123 for conveying the card 20 to the transmission unit 130. A card blocking member 124 is provided at the ejection opening 123. The distance between the card blocking member 124 and the upper surface of the first conveyor belt 122 is greater than the thickness of one card and less than the thickness of two cards, so that only one access card can enter and exit the ejection opening 123. Specifically, the thickness of a highway access card is about 5 mm. Therefore, the distance between the card blocking member 124 and the upper surface of the first conveyor belt 122 is greater than 5 mm and less than 10 mm. In this embodiment, the card loading box 111 has a funnel-shaped structure, and the area of the upper opening is larger than the area of the bottom opening. During use, the access cards are poured into the card loading box 111. Due to the action of gravity, the access cards 20 will fall onto the first conveyor belt 122 of the sorting unit 120 and be driven by the first conveyor belt 122 to the ejection opening 123. In this embodiment, the card loading box 111 can accommodate about 300 access cards at a time. According to needs, the volume of the card loading box 111 can also be adjusted according to actual needs. In this embodiment, the card blocking member 124 is a first rubber roller, and the first rubber roller is rotatably provided at the ejection opening 123. The movement direction of the lower surface of the first rubber roller is opposite to the movement direction of the upper surface of the first conveyor belt 122. In this embodiment, the first rubber roller includes a metal body and a flexible plastic layer wrapped around the outer surface of the metal body.

[0046] In this embodiment, the sorting unit 120 further includes a first motor 125, a first transmission shaft 126, and a second transmission shaft 127. The first transmission shaft 126 is disposed inside the first conveyor belt 122 to drive the first conveyor belt 122 to move. The second transmission shaft 127 is disposed inside the card stopper 124 (first rubber roller) to drive the card stopper 124 (first rubber roller) to rotate. The first motor 125 is connected to the first end of the first transmission shaft 126 to drive the first transmission shaft 126 to rotate. The second end of the first transmission shaft 126 is connected to the second transmission shaft 127 to drive the second transmission shaft 127 to rotate. Since the movement direction of the lower surface of the card stopper 124 (first rubber roller) needs to be opposite to the movement direction of the upper surface of the first conveyor belt 122, at this time, the rotation directions of the first transmission shaft 126 and the second transmission shaft 127 should be the same. Therefore, transmission members such as a chain or a belt can be used to connect the first transmission shaft 126 and the second transmission shaft 127 to make their rotation directions the same. Specifically, a first sprocket 1251 is provided on the rotor of the first motor 125. A second sprocket 1261 is provided at the first end of the first transmission shaft 126, and the first sprocket 1251 and the second sprocket 1261 are connected by a transmission chain 1262. Specifically, a first pulley 1263 is provided at the second end of the first transmission shaft 126, a second pulley 1271 is provided on the second transmission shaft 127, and the first pulley 1263 and the second pulley 1271 are connected by a belt 1272. During the actual working process, the first motor 125 drives the first transmission shaft 126 to rotate. Correspondingly, the first conveyor belt 122 disposed on the transmission shaft 126 will be driven by the transmission shaft 126 to drive the card to move toward the card outlet 123. Due to the blocking effect of the card stopper 124, only one card can enter and exit the card outlet 123, so that the cards can be output to the transmission unit 130 in sequence. In addition, since the card stopper 124 is rotatably disposed at the card outlet 123, and the movement direction of the lower surface of the card stopper 124 is opposite to the movement direction of the upper surface of the first conveyor belt 122. When two cards 20 overlap, the card stopper 124 can push the upper card 20 inward to make its movement direction opposite to that of the lower card 20, thereby effectively separating the two cards 20. As required, a tension pulley 128 is provided on the bracket 121 of the sorting unit 120, and the tension pulley 128 is connected to the first pulley 1263 and the second pulley 1271 by a belt 1272. The tension pulley 128 is used to adjust the belt tension between the first pulley 1263 and the second pulley 1271.During actual use, after the first motor 125 rotates forward (causing the upper surface of the first conveyor belt 122 to move towards the card outlet 123) for a period of time t1, it first rotates backward (causing the upper surface of the first conveyor belt 122 to move away from the card outlet 123) for a period of time t2, and then continues to rotate forward for time t1, and so on in a cycle. The forward rotation time t1 is greater than the backward rotation time t2. The purpose of this setting is to prevent the cards 20 from accumulating in the area of the card loading box 111 near the card outlet 123, so that the cards can be roughly evenly distributed on the card loading box 111.

[0047] According to needs, a touch screen housing 129 can also be provided on the bracket 121. The touch screen housing 129 is used to set the touch screen 160. The user can operate the card sorting machine 100 through the touch screen 160.

[0048] Please also refer to Figures 5 to 6, the transmission unit 130 includes a transmission bracket 131, a second conveyor belt 132 and a card slot 133 provided on the transmission bracket 131. The entrance of the card slot 133 is located at the bottom of the card outlet 123 provided between the loading box 111 and the upper surface of the first conveyor belt 122. The outlet of the card slot 133 is located on the upper surface of the second conveyor belt 132. The upper surface of the second conveyor belt 132 moves in the direction of the detection unit 140 from the outlet of the card slot 133, and is used to convey the card 20 to the detection unit 140. In this embodiment, the card slot 133 is also funnel-shaped. After the card 20 comes out of the card outlet 123 between the loading box 111 and the upper surface of the first conveyor belt 122, it will fall to the entrance of the card slot 133 due to the action of gravity, and then fall to the upper surface of the second conveyor belt 132 through the card slot 133. The card slot 133 is set to be funnel-shaped to increase its receiving area and prevent the card from falling to other areas of the transmission unit 130. Specifically, the transmission unit 130 further includes a second rubber roller 134, and the second rubber roller 134 is rotatably provided on the upper surface of the second conveyor belt 132. The movement direction of the lower surface of the second rubber roller 134 is opposite to the movement direction of the upper surface of the second conveyor belt 132. The function of the second rubber roller 134 is similar to that of the first rubber roller 124. When two cards overlap, the second rubber roller 134 can push the card located above inward to make its movement direction opposite to that of the card located below, so as to effectively separate the two cards. Specifically, the transmission unit 130 further includes a second motor 135, a third transmission shaft 136 and a fourth transmission shaft 137. The third transmission shaft 136 is provided inside the second conveyor belt 132 to drive the second conveyor belt 132 to move. The fourth transmission shaft 137 is provided inside the second rubber roller 134 to drive the second rubber roller 134 to rotate. The second motor 135 is connected to the first end of the third transmission shaft 136 to drive the third transmission shaft 136 to rotate. The second end of the third transmission shaft 136 is connected to the fourth transmission shaft 137 to drive the fourth transmission shaft 137 to rotate. Specifically, a third sprocket 1351 is provided on the rotor of the second motor 135. A fourth sprocket 1361 is provided at the first end of the third transmission shaft 136, and the third sprocket 1351 and the fourth sprocket 1361 are connected by a transmission chain 1362. Specifically, a third pulley 1363 is provided at the second end of the third transmission shaft 136, a fourth pulley 1371 is provided on the fourth transmission shaft 137, and the third pulley 1363 and the fourth pulley 1371 are connected by a belt 1372.

[0049] Please refer to Figure 7 and Figure 8, the detection unit 140 and the card dropping slot 133 are respectively arranged at two ends of the second conveyor belt 132. The detection unit 140 includes a first surface 141 and a second surface 142. The first surface 141 faces downward and faces the upper surface of the second conveyor belt 132. The orientation of the second surface 142 is opposite to that of the first surface 141. A guiding channel 143 is provided on the first surface 141. The guiding channel 143 has a first end 1431 close to the card dropping slot 133 and a second end 1432 far from the card dropping slot 133. The opening width of the first end 1431 of the guiding channel 143 is larger than that of the second end 1432 of the guiding channel 143. Specifically, the opening size of the second end 1432 of the guiding channel 143 is set to be only able to accommodate the width of one highway toll card. In this embodiment, the opening size of the second end 1432 of the guiding channel 143 is set to be larger than the width 54 mm of the highway toll card and smaller than the length 85.5 mm of the highway toll card. In this embodiment, there are two guiding channels 143, which are respectively arranged on both sides of the detection unit 140 in the width direction. First guide rails 1433, second guide rails 1434, third guide rails 1435 and fourth guide rails 1436 are provided on the first surface 141. The first guide rails 1433 and the second guide rails 1434 are respectively arranged on both sides of the first surface 141 in the width direction. One ends of the first guide rails 1433 and the second guide rails 1434 close to the card dropping slot 133 open outward to form a flared shape. The third guide rails 1435 and the fourth guide rails 1436 are arranged inside the first surface 141. The third guide rails 1435 and the first guide rails 1433 form a guiding channel 143. The fourth guide rails 1436 and the second guide rails 1434 form another guiding channel 143. One ends of the third guide rails 1435 and the fourth guide rails 1436 close to the card dropping slot 133 incline inward and are connected together to form an inverted V-shaped structure.

[0050] As needed, a pusher pin 1437 is further disposed in the guiding channel 143. The pusher pin 1437 reciprocates in the moving direction of the second conveyor belt 132. In this embodiment, a pusher pin movement groove 14371 is further disposed in the guiding channel 143. The pusher pin movement groove 14371 extends along the moving direction of the second conveyor belt 132, and the pusher pin 1437 reciprocates in the pusher pin movement groove 14371. Since the card is rectangular, and the width of the guiding channel 143 provided on the first surface 141 is smaller than the longest side of the card. When the pusher pin 1437 is disposed in the guiding channel 143, the pusher pin 1437 pushes the card to change the moving direction of the card. Therefore, the pusher pin 1437 is used to convey the card from the first end 1432 of the guiding channel 143 to the second end 1431 of the guiding channel 143 through the second conveyor belt 132.

[0051] As needed, the detection unit 140 is further provided with a plurality of sensors 144. The sensors 144 are disposed on the second surface 142 of the detection unit 140 and within the vertical projection area of the guiding channel 143. The sensors 144 are used to detect the residence time of the card in the spare card area. When the residence time exceeds the preset time, the sensors 144 send signals to the main control board of the card collator 100 to control the reverse rotation of the second conveyor belt 132.

[0052] In this embodiment, the detection unit 140 further includes a reading and writing antenna 145 and an ejecting mechanism 146. The reading and writing antenna 145 is disposed at the second end 1431 of the guiding channel 143. A step portion 1438 is provided at the second end 1431 of the guiding channel 143, and the step portion 1438 is used to temporarily fix the position of the card to facilitate the reading and writing of the information of the card 20 by the reading and writing antenna 145. The ejecting mechanism 146 is disposed beside the step portion 1438, and the ejecting mechanism 146 is used to eject the card 20 out of the step portion 1438 by the suction of the electromagnet after the reading and writing of the card information is completed, so that the card 20 continues to move toward the recycling unit 150. In this embodiment, the ejecting mechanism 146 is an electromagnet, and the electromagnet realizes the function of ejecting the card 20 by sucking or releasing the ejector pin 1461 beside the step portion 1438. As needed, a blocking member can also be directly provided to block the movement of the card. After the reading and writing of the card information is completed, the blocking member is lifted or retracted, so that the card continues to move toward the recycling unit 150. In this embodiment, the operating frequency of the reading and writing antenna 145 is 13.56 MHz, and it emits and receives electromagnetic waves of 13.56 MHz to communicate with the antenna unit in the card.

[0053] Please refer to Figures 9 to 10, the detection unit 140 further includes a sorting unit 147. The sorting unit 147 is disposed at one end of the reading and writing antenna 145 away from the card dropping slot 133, and is used to sort the cards 20 according to the quality of the cards 20. The information feedback processed by software between the sorting unit 147 and the reading and writing antenna 145 is fed back to the sorting unit 147. When the card information read by the reading and writing antenna 145 through the 13.56 MHz radio frequency antenna is correct, the sorting unit 147 makes the card 20 move in the first direction to be transmitted to the recycling unit 150. When the reading and writing antenna 145 cannot read the card information through the 13.56 MHz radio frequency antenna, the sorting unit 147 makes the card move in the second direction to be transmitted to the bad card unit 170. Specifically, the sorting unit 147 includes a bracket 1471, an electromagnet 1472 and a suction member 1473 disposed on the bracket 1471. The suction member 1473 includes a first end 1474 and a second end 1475. The first end 1474 of the suction member 1473 can be attracted or released by the electromagnet 1472 so that the second end 1475 of the suction member 1473 is lifted or lowered. A rocker 1476 is disposed at the second end 1475 of the suction member 1473. When the electromagnet 1472 is energized, the electromagnet 1472 attracts the first end 1474 of the suction member 1473, thereby lifting the rocker 1476 to be in the second position. When the electromagnet 1472 is de-energized, due to the action of a spring (not shown) disposed inside, the rocker 1476 is lowered to be in the first position. Therefore, the electromagnet 1472 can make the rocker 1476 move between the first position and the second position by attracting or releasing the suction member 1473. When the rocker 1473 is in the first position, the card can continue to move towards the recycling unit 150 through the supporting action of the rocker 1476. When the rocker 1476 is in the second position, since the rocker 1476 is lifted, the second conveyor belt conveys the card that cannot read the card information to the bad card unit 170. As required, a transmission wheel can also be disposed on the rocker 1476 to reduce the friction force when the card moves on the rocker 1476. As required, a sliding groove can also be disposed on the bracket 1471. The rocker 1476 can move on the sliding groove to limit the moving position of the rocker 1476. When the rocker 1476 moves to the bottom of the sliding groove, the rocker 1476 is in the first position. When the rocker 1476 moves to the top of the sliding groove, the rocker 1476 is in the second position.
