[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: the logistics sorting device places the goods on the first conveyor belt for conveying.

[0015] s1. When the goods are transported from the first conveyor belt to the sorting belt and detected by the infrared sensor, the sorting belt and the second conveyor belt are driven at the same time, and the sorting belt will transport the goods to the second conveyor belt;

[0016] s2. When the goods are completely transported to the second conveyor belt, the goods are out of the detection distance range of the infrared sensor. At this time, the delay device is triggered, causing the motor to stop working after a delay. When the goods are transported out of the second conveyor belt, the delay device automatically closes after the delay time ends, and the motor stops working, causing the second conveyor belt and the sorting belt to stop working at the same time.

[0017] When the goods are transported out from the second conveyor belt, the motor stops working, and the second conveyor belt and the sorting belt stop working at the same time, which can stop the motor in time to save energy consumption and further reduce the loss of the second conveyor belt and the sorting belt.

The infrared sensor 9 is fixedly installed on the first rotating rod 65 away from the second conveyor belt 52.

[0029] See also Figure 1-Figure 4The driving assembly includes a motor 61, a driving shaft 60, two rollers 66 connected by the sorting belt 3, and a first rotating rod 65 fixedly connected to the bottom end of the roller 66. A first bottom plate 1 is provided below the first conveyor belt 2, and two fixed seats 64 are fixedly connected to the first bottom plate 1. A rotating shaft 62 rotatably connected to the fixed seat 64, and a worm gear 63 is fixedly connected to the rotating shaft 62. The first rotating rod 65 is connected to the rotating shaft 62 directly below it by a lifting assembly. The driving shaft 60 is driven by the motor 61, and the driving shaft 60 is provided with a worm segment 600 meshing with the worm gear 63.

[0030] See also Figure 3-Figure 5 The lifting assembly includes a sleeve 70 fixedly connected to the top of the rotating shaft 62, an electric push rod 71 installed in the sleeve 70, and the piston rod end of the electric push rod 71 is connected to the bottom end of the first rotating rod 65. The electric push rod 71 can push the first rotating rod 65 and the sorting belt 3 to move up and down, and the sorting belt 3 can be adjusted to a suitable height, so that goods of different heights can be screened.

[0031] See also Figure 5 , a scale line 650 is provided on the rod body of the first rotating rod 65. The scale line 650 is convenient for better observing the height of the lifting adjustment of the sorting belt 3, so as to more accurately adjust the sorting belt 3 to the required height position.

[0032] See also Figure 1 The second conveyor belt 52 is driven by two transmission rollers 51, one end of one transmission roller 51 is connected to a second rotating rod 83, and the driving shaft 60 and the second rotating rod 83 are driven to rotate synchronously by a linkage assembly. The transmission roller 51 is rotatably mounted on the U-shaped frame 50, and a second bottom plate 4 is provided below the second conveyor belt 52, and the U-shaped frame 50 is mounted on the second bottom plate 4.

[0033] See also Figure 1 , Figure 3 and Figure 5 The linkage assembly includes a main pulley 80 fixedly connected to the driving shaft 60, a slave pulley 81 fixedly connected to the second rotating rod 83, and a belt 82 for connecting the main pulley 80 and the slave pulley 81. The rotation of the driving shaft 60 drives the main pulley 80 to rotate, thereby driving the slave pulley 81 and the second rotating rod 83, so as to drive the second conveyor belt 52 to work.

[0034] In the present invention, when screening logistics, the goods are placed on the first conveyor belt 2 for transportation. When the height of the goods is lower than the bottom height of the sorting belt 3, the goods will be transported out from under the sorting belt 3. During this process, the infrared sensor 9 does not detect the goods, and the motor 61 will not work to generate energy consumption.

[0035] When the height of the goods is higher than the bottom height of the sorting belt 3, the goods are transported to the point where they come into contact with the sorting belt 3 and will be blocked by the sorting belt 3. At this time, the infrared sensor 9 will detect the goods and transmit the signal to the motor 61 to make it work. The motor 61 will drive the drive shaft 60 to rotate, and through the worm section 600 meshing with the worm wheel 63, it will drive the rotating shaft 62 to rotate, thereby driving the roller 66 to rotate, so that the sorting belt 3 drives and transports the goods to the second conveyor belt 52. When the drive shaft 60 rotates, it will drive the belt 82 and the pulley 81 to rotate, thereby driving the second rotating rod 83 and the transmission roller 51 to rotate, driving the second conveyor belt 52 to rotate synchronously with the sorting belt 3. The same motor 61 drives the second conveyor belt 52 and the sorting belt 3 to rotate simultaneously, with better synchronization, so that the second conveyor belt 52 and the sorting belt 3 can move more stably. When part of the goods is located on the first conveyor belt 2 and part is located on the second conveyor belt 52, the second conveyor belt 52 is synchronously driven with the sorting belt 3, so that the goods can be stably transported to the second conveyor belt 52.

[0036] The detection distance of the infrared sensor 9 is equal to the distance between the two rollers 66. The screening mechanism also includes a delay device for delaying the motor 61 to stop working. The delay device, the motor 61 and the infrared sensor 9 are all connected to the controller.

[0037] It is worth noting that the timer, the motor 61 and the infrared sensor 9 are all conventional technologies and will not be described in detail here.

[0038] Based on this embodiment, a logistics screening method can be provided. The method is performed using the logistics sorting device provided in this embodiment, and specifically includes the following steps:

[0039] s1. When the goods are transported from the first conveyor belt 2 to the sorting belt 3 and detected by the infrared sensor 9, the sorting belt 3 and the second conveyor belt 52 are driven at the same time, and the sorting belt 3 transports the goods to the second conveyor belt 52;

[0040] s2. When the goods are completely transported to the second conveyor belt 52, the goods are out of the detection distance range of the infrared sensor 9. At this time, the delay device is triggered, causing the motor 61 to stop working after a delay. When the goods are transported out of the second conveyor belt 52, the delay device automatically turns off after the delay time ends, and the motor 61 stops working, causing the second conveyor belt 52 and the sorting belt 3 to stop working at the same time.

[0041] When the goods are screened and completely transported to the second conveyor belt 52, the goods exceed the detection range of the infrared sensor 9. At this time, the infrared sensor 9 transmits a signal to the controller. The controller controls the delay device to trigger and controls the motor 61 to stop working after a delay. When the goods are transported out from the second conveyor belt 52, the delay device automatically turns off after the delay time ends, and the motor 61 stops working, so that the second conveyor belt 52 and the sorting belt 3 stop working at the same time, avoiding the loss caused by the second conveyor belt 52 and the sorting belt 3 continuing to work.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
