Structure of guide rail slider of logistic sorting machine

Abstract

The invention discloses a structure of a guide rail slider of a logistic sorting machine. A guide rail is formed by connecting a pair of parallel left monorail and right monorail into a whole through the crossbeams at the top thereof; two monorails and the crossbeams enclose a groove; the bottom of the monorail is provided with an opening; the lower part of the slider is provided with a left through hole and a right through hole; the through hole is matched with the appearance of the monorail; a convex plate protruding upwards is formed between the through holes; installing holes are arranged on a base plate of the slider up to the top of the convex plate; the base plate of the through hole extends out to one side to form a pressing sheet the cross section of which is in a reversed L shape; the side wall of the convex plate protrudes into the through hole to form a shrapnel; the guide rail penetrates through the through hole; the convex plate is positioned in the groove; the free end of the pressing sheet is propped and pressed on the edge of the opening; and the protruding end of the shrapnel is propped and pressed on the inner wall of the groove. In the structure provided the invention, the dimensional precision requirements of the parts are lowered, and the guiding smooth is good after the structure is assembled; an integrated structure is adopted in the guide rail, thus removing the influence of the installation accuracy of the guide rail on the guiding smooth of the slider; the deformation generated by the guide rail used for a long time can absorbed by the slider; and the parts are fewer, thus the assembly is simple and convenient.

Description

technical field [0001] The invention relates to a logistics sorting machine, in particular to a guide rail slider structure. Background technique [0002] The logistics sorting machine is one of the key equipment for classifying and sorting logistics in logistics distribution. Its main structure is a long strip conveyor belt for circular transportation. The conveyor belt is paved with multiple parallel guide rails. The length of the guide rail is equal to Conveyor belt width, sliders are installed on the guide rail, and the sliders can slide along the length of the guide rail. All the sliders are arranged in a row on one side of the entire conveyor belt, and there are multiple different sorting outlets on the other side of the conveyor belt. [0003] When the sorting starts, the items to be sorted enter the feeding end of the conveyor belt, the items to be sorted are located between the slider and the sorting outlet, the conveyor belt starts to convey, and the barcode on the...

Problems solved by technology

[0005] This structure has the following defects: First, the outer edge of the lining and the inner cavity of the guide rail are in full contact and fit. In order to control the guiding accuracy, the gap between the lining and the inner cavity of the guide rail is designed to be relatively small, generally about 0.5mm, and the guiding accuracy It is completely determined by the mold opening accuracy of the parts, and the requirements for the mold are very high; the second is to ensure the gap between the lining and the inner cavity of the guide rail, which is limited by the size of the inner cavity of the guide rail, resulting in the lateral protrusion of the upper and lower ends of the lining. The thickness cannot exceed 2mm, the elastic force after assembly is too small, and it cannot be thickened, and the guiding smoothness is not good; the third is that the metal connector used to connect the two linings will be deformed due to various external forces during long-term work. If it is generated, it will seriously affect the guiding accuracy and smoothness of guiding, resulting in a sharp increase in sliding friction, and even the phenomenon of slider jamming; the fourth is to use two independent monorails combined as a group to guide the slider. When the rails are deformed, or when the deformation directions of the two aluminum rails are inconsistent, the sliding friction force will rise sharply, and even the slider will be stuck; fifth, the sliders, guide pins, linings, and metal connectors are all independent parts , the assembly process of the slider assembly is complicated, and the assembly requirements are very high; six, the installation accuracy between the guide rail and the slider is high, and each time a slider is installed on a set of guide rails, the two guide rails must be repositioned
