Description

[Detailed explanation of the idea]

Currently, belt conveyors play a large role in the transportation of raw materials and products in various factories. This resulted in major disruptions to work due to shutdowns and disposal of fallen objects. The present invention aims to provide a device that can safely and easily adjust the meandering of a belt conveyor as a measure to prevent meandering. The present invention will be explained with reference to the drawings. As shown in FIGS. 1 and 2, the roller 3 is supported by a supporting metal fitting 6 by sandwiching the shafts 4 and 4' at both ends, and the supporting metal fitting 6 is further provided with a freely movable spherical bearing 5 at the lower center thereof. A mounting base 7 is fixed to a belt conveyor frame 8, and the rollers 3 are installed in the vicinity of the tail pulley 1 of the belt conveyor and below the return belt 2 in a horizontal position with the belt, as shown in FIG. Further, an adjustment arm 10 consisting of a fan-shaped horizontal adjuster 11 and a vertical adjuster 12 with left and right (ABC) and upper and lower (abc) pin holes provided on the support 9 on one side of the conveyor frame 8 is attached, and one side is supported. Fixed to one side of hardware 6, and the other is pin 1
An adjustment lever 13 is provided which is fixed to a pin hole of the vertical adjuster 12 via 4 and 14'. Next, an example of use of the present invention will be explained. The meandering adjustment device of the present invention operates a belt conveyor, and while the conveyed object is still on the conveyor, the adjustment lever is moved left and right by the horizontal adjuster and the vertical adjuster.
You can move the conveyor to the right or left by moving it up or down. In other words, when the belt conveyor is operating smoothly, the adjustment lever is fixed at the intermediate position between the vertical and horizontal adjusters (B and b), but if the belt conveyor shifts to one side (meandering) for some reason. If this occurs, the adjustment lever is fixed to an appropriate position on the vertical adjuster and then slid along the horizontal adjuster and fixed to the left or right position to adjust the deviation of the belt conveyor. The following table shows that the device of the present invention was installed on a belt conveyor with a width of 600 m/m, and the load on the belt conveyor was varied from 21 tons/hour to 53 tons/hour (10 times), and the position of the adjustment lever was changed. This figure shows the direction of deviation of the belt conveyor and the movement dimension of the belt conveyor.

[Table] According to the table above, there is almost no effect of deviation due to changes in load, and therefore meandering can be prevented by adjusting the belt conveyor in the opposite direction depending on the degree of deviation on either the left or right side. It can be prevented. As described above, according to the device of the present invention, it is possible to forcibly tilt the rollers using the adjustment lever and use the resulting resistance (pushing force) to move the belt conveyor in any direction and adjust the deviation. Furthermore, since the inclination of the rollers can be adjusted not only horizontally (left and right) but also in the vertical direction, it is possible to correct the inclination of the belt conveyor. Further, by appropriately increasing the number of adjustment pin holes, more fine adjustment can be made. As described above, with the present invention, it is possible to correct the deviation that occurs during the operation of the belt conveyor with a simple device, there is almost no falling of conveyed objects, and there is no damage to the belt conveyor. Wasteful work has been eliminated, and transportation work at the factory has become more efficient.
