Guide wheel device capable of preventing sudden changing and reversing, sorting trolley and crossed belt sorting machine

Abstract

The invention discloses a guide wheel device capable of preventing sudden changing and reversing, a sorting trolley and a crossed belt sorting machine. The guide wheel device comprises a first connecting rod and a second connecting rod, wherein the first connecting rod and the second connecting rod are movably connected with a trolley bottom plate, guide wheels are arranged at the two ends of thefirst connecting rod and the two ends of the second connecting rod correspondingly, and the guide wheels are provided with vertical rotating axes; and an elastic piece is connected between the first connecting rod and the second connecting rod, and rotating points of the first connecting rod and rotating points of the second connecting rod are located on the same side of the elastic part. According to the technical scheme, the guide wheels at the two ends of the first connecting rod and the two ends of the second connecting rod are always in flexible contact with an inner guide rail through the elastic piece, the situations that the guide wheels are separated from the inner guide rail and change direction are avoided, vibration impact and noise are avoided, the possibility that the guide wheels are separated from a belt is reduced, so that the service life is prolonged, and the impact on a vertical rod is reduced.

Description

technical field [0001] This application generally relates to the technical field of logistics automatic sorting, and in particular relates to a guide wheel device for preventing sudden change and reversing, a sorting trolley and a cross-belt sorting machine. Background technique [0002] The cross-belt sorter is a new type of logistics sorting equipment, which can realize the rapid sorting of goods and is widely used in express delivery, e-commerce, clothing and other industries. The sorting trolley is the most important part of the cross-belt sorter, and it is the main carrier to realize the sorting of goods. [0003] The top of the existing sorting trolley is covered with a belt. When the sorting trolley moves along the forward direction, the belt can roll along the direction perpendicular to the forward direction, and the parcels on the belt are transported and dropped to the side of the trolley. [0004] Such as figure 1 As shown in the schematic diagram of cooperation...

AI Technical Summary

Problems solved by technology

[0004] like figure 1 As shown in the schematic diagram of cooperation between the existing trolley guide device and the guide rail, four support wheels 100 are connected to the bottom plate of the trolley, and two guide wheels 101 are arranged on the bottom of the trolley floor. The wheel 101 is arranged in the middle of the bottom of the trolley, and the guide wheel is in contact with the inner guide force-bearing surface 104 of a pair of inner guide rails 103. When the trolley is turning or moving forward, the guide wheel 101 is between the two guide force-bearing surfaces 104. Switch between the contact, so that the guide wheel 101 can quickly switch between counterclockwise movement and clockwise movement, the speed change is very large, resulting in severe friction between the guide wheel and the inner guide rail, causing vibration of the trolley, increasing noise, and reducing degumming of the guide wheel of the trolley service life, not conducive to normal operation
