A control method for finished product stacking of finishing line

Abstract

The invention discloses a control method for stacking of plate finishing line finished products. A control system, a movable baffle and a falling steel plate are adopted. The control method comprises steps as follows: production preparation work is performed; an operating line is started; an outlet speed signal is uploaded to the control system; a sensing grating for detecting the position of the steel plate is arranged nearby an inlet of the movable baffle to detect a steel plate position signal; after the steel plate position signal is detected, horseshoe rollers are turned over after a period, so that the steel plate falls down; the movable baffle beats the steel plate and stacking is finished; the steel plate falling manner in Step 5) adopts a parabola falling manner. The horseshoe roller steel plate throwing manner is optimized, the steel plate is ensured to fall down in the preset position, and bounces caused by collisions with the movable baffle are reduced, so that bale stack shapes are guaranteed; the station of the movable baffle is improved and the beating function is added, the steel plate is adjusted in the length direction, and stack shape out-of-tolerance is prevented. The quality problem of irregular thick plate cross-cutting line finished product bale stack shapes is effectively solved.

Description

technical field [0001] The invention relates to the field of packaging and bundling of hot-rolled plates, in particular to a technology for improving the packing and stacking quality of finished plate products and ensuring the stacking shape of finished products. Background technique [0002] The hot-rolled finished plate is a part of the hot-rolled commercial material, and is directly sent to the end user in the form of a bundle (multiple steel plates are stacked together to form a bundle). The stack shape is one of the important quality requirements for the hot-rolled commercial material. If the stacking is not good, it will not only affect the appearance quality of the product, but also affect the packaging of the subsequent process, especially the box packaging, as well as the intermediate logistics links and the user's transportation and hoisting. [0003] The most important means of quality control of hot-rolled sheet bundles is the use of movable baffles, through the ...

AI Technical Summary

Problems solved by technology

[0007] It turns out that the steel plate is stopped by the movable baffle and dropped on the pallet trolley, and the mechanical blocking method is adopted. Since the steel plate enters the pallet table at a very fast speed, it directly collides with the movable baffle, which has a great impact on the equipment. large, often damaged

At the same time, the fast-moving steel plate has great inertia, and the movable baffle is driven by the cylinder. The movable baffle will be impacted and its position will change, resulting in uneven bales in the length direction, especially for the production of some thick steel plates. It is especially obvious when it is used, sometimes even the movable baffle will be washed away, and the stacking shape of the bale cannot be guaranteed.
