Description

Automatic alignment device for meandering adjustment

The present invention relates to an automatic alignment device for meandering adjustment, and more particularly, to an automatic alignment device for meandering adjustment in which the center of a belt is adjusted by displacement according to the left and right displacement of the belt.

In general, a belt conveyor used to transport goods at industrial sites such as power generation facilities has a configuration in which the goods discharged from the storage tank located on the upper side of one side are loaded on the upper part of the belt moving in the form of an endless track.

In such a belt conveyor, it is preferable that the conveyed material discharged through the storage tank is dropped and loaded at the center of the belt conveyor, but the drop point in the storage tank varies depending on the specific gravity and moisture content of the conveyed material, and the conveyed material is attached to the support roller Under the influence of such factors, the drop point on the conveyor belt is also changed. This phenomenon is called bias.

The belt guide part 337 is coupled to the guide rotation shaft 333 at the top and bottom of the roller body 331 and extends inward in the width direction. The belt guides 337 provided vertically on the guide rotation shaft 333 face each other and are spaced apart. The belt (B) of the belt conveyor is slidably inserted between the belt guides 337, and both ends in the width direction are provided toward the roller body 331.

By providing the belt guide part 337, even if a strong meandering force acts on the belt conveyor, separation of the belt B is prevented, and a large belt meandering force is transmitted, so that automatic adjustment of the meandering is performed quickly. In addition, since the distance between the belt B and the roller body 331 can be reduced during installation, it can be adjusted in response to a small meandering speed.

As shown in FIG. 13, the automatic alignment device 300 for meandering adjustment may be provided on the frame horizontal member F1 and positioned above the belt B.

In the self-aligning device for meandering adjustment according to the present invention (200, 300), a plurality of stand bodies (221, 321) are rotatably coupled to the link parts (240, 340) via the connecting members (243, 343), and the meandering The

guide rollers

230 and 330 are pressed by the belt B, and the plurality of

stand bodies

221 and 321 rotate around the respective

stand rotation shafts

2211 and 3211 as a center of rotation, so they respond quickly to meandering. It rotates, and the plurality of

stand bodies

221 and 321 are in a side-by-side state as shown in FIGS. 9 and 10, making smooth contact with the belt B, and as shown in FIG. 4, both sides are upward and concave in the middle. Automatic meandering adjustment is also performed smoothly on the conveying side.
