Description

Technical Field

[0001] The present invention relates to the technical field of material sorting, and in particular to a logistics terminal sorting system based on the Internet of Things. Background Art

[0002] Logistics terminal sorting, as the name implies, is the process of carefully classifying and categorizing goods at the end of the logistics process. Its purpose is to ensure that the goods can be delivered to the end customers accurately and improve logistics efficiency and customer satisfaction. Generally, the express is coded by manual scanning and then placed in the corresponding layer of the express rack, so that customers can find the express quickly.

[0003] When express delivery is sorted manually, a large number of express delivery codes need to be scanned and the express delivery must be placed on different levels of the express delivery rack; this will cause workers to constantly stand and bend over, consuming a lot of physical energy, which can easily make workers feel tired, and the sorting efficiency is also low; some express delivery sorting devices use robotic arms to clamp the express delivery and then transfer it to the express delivery rack, which can improve the sorting efficiency of the express delivery; however, it is more convenient for robotic arms to clamp express delivery packaged in cartons, while items such as clothing are generally packaged in plastic bags, which are not easy to clamp with robotic arms. When the robotic arm only clamps the plastic bag but not the clothes inside the plastic bag, the clothes are easy to move down to the bottom of the plastic bag, which is not convenient for stacking the express delivery on the express delivery rack later, and further improvements can be made.

[0023] The motor 1 502 drives the threaded rod 1 503 to rotate, driving the slide 404 to slide along the slide rail 501, thereby driving the vertical plate 401 and the horizontal plate 402 to move left or right. In this process, the roller 403 rolls on the top of the top plate 200.

[0024] See also Figure 2 and Figure 5 The longitudinal bracket 600 includes a support plate 601 fixedly mounted on the top of the horizontal plate 402.

In addition, the cross section of the convex strip 604 can be an isosceles trapezoid, and the sliding groove 703 is adapted to the convex strip 604, which further prevents the sliding plate 701 from being separated from the arc plate 603.

The cross section of the rotating shaft 705 is in a "convex" shape. The rotating shaft 705 is adapted to the inner wall of the sleeve 704. A fixed cover 706 is fixedly installed on the front end of the rotating shaft 705, and a placement plate 707 is fixedly installed on the front side of the fixed cover 706. The placement plate 707 is initially in a horizontal state and is used to lift bagged express. A motor 3 708 is fixedly installed on the front side of the sliding plate 701, and a gear 2 709 is fixedly installed on the output end of the motor 3 708.

When the suction pump 716 sucks air, it cooperates with the connecting pipe 715, the L-shaped hole 714, the shaft sleeve 704, and the air guide hole 712 to make the negative pressure inside the negative pressure chamber 711. Then, the bagged express on the top of the placement plate 707 is adsorbed through the adsorption hole 713 to prevent the bagged express from falling off the placement plate 707 during the movement of the placement plate 707.

[0029] See also Figure 8-Figure 9 , an air inlet 1 717 is provided at the top of the rotating shaft 705, and the air inlet 1 717 is connected to the air guide hole 712. Two groups of air inlet 2 718 are provided through the circumferential surface of the shaft sleeve 704, and the two groups of air inlet 2 718 are distributed on the left and right.

When the express packages are stacked to nearly half the length of the layer, place them from the right end of the layer to the left, so that the last express package placed on the layer is in the middle of the layer.
