Long pipe sorting feeder and sorting feeding method

Abstract

The invention relates to a sorting feeding machine for long pipes and a sorting feeding method, comprising a frame, a feeding conveyor belt arranged on the frame, a feeding device arranged in front of the feeding conveyor belt, and a silo device arranged behind the feeding conveyor belt, at least A row of feeding conveyor belts is arranged separately on the left and right sides of the frame. A row of feeding conveyor belts includes a front conveyor belt that can rub and run and a rear conveyor belt that moves forward in one direction; The conveyor belts are separated from the left and right, and there is a partial overlap area between them from the side view; the front conveyor belts separated from the left and right sides are set synchronously, and the rear conveyor belts separated from the left and right sides are also set synchronously. In this way, the stacked pipes can continuously adjust themselves, straighten out the kinks and gradually become independent. Because the present invention has the above-mentioned characteristics and advantages, it can be applied to a device for sorting and feeding long pipes and can effectively implement sorting work.

Description

technical field [0001] The invention relates to a material conveying device and a material conveying method thereof, in particular to a sorting and feeding device and a material conveying method for elongated pipes such as steel pipes, plastic pipes and other pipes with relatively thin wall thickness. The feeding direction is not the direction in which the pipe extends axially but the radial direction. Background technique [0002] For pipe products such as steel pipes, plastic pipes, etc., especially thin-walled pipe products, they have a certain ability to resist shear force from a local point of view, and they will not be twisted or mixed together if the length is not too long. However, if the length is too long, for example, the ex-factory length of this pipe is generally defined as 12 meters, 6 meters or 4 meters, etc. When a pile of such pipes are placed together, the problem of twisting at the end and the end will easily occur, so as to apply this pipe in the next pro...

AI Technical Summary

Problems solved by technology

The main point of this device is to use the principle of steel pipes falling by their own weight and mechanical vibration to promote the automatic separation and sorting of steel pipes, but its defects are very obvious. The sorting effect is not good. Generally, at least one person needs to follow the machine to assist in the selection of pipes with a relatively large degree of kink. Therefore, the automatic sorting effect is very limited.
