The present invention relates to a meandering adjustment device for a conveyor belt, and more particularly, to meander and adjust the meandering by automatically contacting the back portion of the conveyor belt when meandering the conveyor belt and returning the meandered conveyor belt to its original position. The present invention relates to a conveyor belt meandering automatic device which prevents belt damage and equipment trouble caused by the belt.

In general, the transportation of fuel raw materials (fuel and raw materials) used in steel mills is conveyed using a conveyor belt, and several conveyor belts are combined to form a line.

1 is a perspective view of a conventional conveyor belt line. As shown in FIG. 1, the shipment 102 carried by the upper conveyor belt 100 is dropped from the chute 104 to the lower conveyor belt 100 to a destination or other conveyor belt (not shown). Are transported.

Once meandering occurs in this transport process, the conveyor belt 100 will continue meandering even in a hollow belt due to its characteristics. Therefore, when the transport object 102 falls from the chute 104, the transport object falls in a meandering form and lands. An example of such meandering is shown in FIG. 2.

This meandering must be adjusted because it damages the conveyor belt 100. That is, by adjusting the progress of the conveyor belt 100, the conveyor belt 100 should be guided to the center when entering the carrier portion through the pulley 106.

In addition, when the meandering occurs, not only the conveyor belt 100 is damaged, but also environmental damage due to equipment damage and falling lights, and the start of the conveyor belt 100 is stopped. This happens.

An example of such improvement is shown in FIG. 3. As shown in FIG. 3, there is an automatic carrier centering roll 110 and an automatic return centering roll 120. The carrier center adjustment roll 110 serves to adjust meandering after the transport 102 is landed on the upper surface of the conveyor belt 100. The return center adjusting roll 120 meanders the conveyor belt 100 traveling in a meandered form to serve as a carrier part. These centering rolls 110 and 120 are guided by the guide roll 112 to guide both sides of the conveyor belt 100 to adjust the meander for adjusting the meandering of the return conveyor belt 100, or to force the return roll stand 122. To make the transport land on the conveyor belt 100 of the carrier. In the meantime, reference numeral 116 denotes a carrier roll, and 126 denotes a return roll.

However, since the centering rolls 110 and 120 are manually adjusted, there is a risk of a safety accident. In addition, the bearing shafts 114 and 124 do not withstand the tension impact pressure of the centering rolls 110 and 120 and the conveyor belt 100 and are easily broken. In addition, the guide roller 122 of the return conveyor belt 100 is also vulnerable to axial rolling, and when the meandering, the opposite guide roll 122 interferes with the surface of the belt 100 to prevent meandering adjustment.

Therefore, the present invention has been made to solve the above-mentioned problems of the prior art, the conveyor belt meandering automatically adjusts the meandering through the contact with the back portion of the conveyor belt when meandering the conveyor belt and returning the meandered conveyor belt to its original position. It is an object to provide an adjusting device.

Wherein the pivot means includes first and second gears engaged with each other at the center of the frame unit; A first gear link integrally extending from the first gear toward the meander detector and having a first slot; A slide bar link integrally extending from said meander detector toward said first gear and movably coupled with said first slot; A second gear link integrally extending from the second gear toward the meander adjusting roll; And a roll stand link having a second slot integrally extending from the meandering adjustment roll toward the second gear and into which the second gear link is fluidly coupled.

8 is a perspective view of a conveyor belt meandering automatic adjustment device according to another embodiment of the present invention.                     

The meander adjustment device shown in Fig. 8 and the meander adjustment device shown in Figs. 4 to 7 are only provided in that they have two pairs of transverse frames 10A and 10B and two pairs of fastening brackets 18A and 18B. The configuration is different and the same in the rest.

On the other hand, the meandering adjustment roll 68 of the present invention is preferably configured to be in contact with the upper surface of the return conveyor belt 100, that is, the return conveyor belt 100 is configured to pass under the meandering adjustment roll 68. Alternatively, the meandering adjustment roll 68 may be configured to contact the bottom surface of the return conveyor belt 100.

9 and 10 will be described the operation of the meandering automatic adjustment apparatus according to the present invention.

First, in FIG. 9, reference numeral 100 denotes a conveyor belt running normally, and reference numeral 100 'denotes a conveyor belt traveling in a state meandered in the A' direction.

When the conveyor belt 100 'meanders in the A' direction, the slide bar 40, which is a meandering sensor, moves in the a direction and drags the slide bar link 46 integrally attached to the b direction in the same direction. When the slide bar link 46 moves in the b direction, the first gear 22 engaged by the slot 28 rotates in the c direction, so that the second gear 30 engaged with the first gear 22 is Rotate in the d direction. The second gear 30 moves in the e direction while also rotating the pin stand roll stand link 58 while rotating in the d direction so that the roll stand 56 rotates or pivots in the f direction. Then, the meandering adjustment roll 68 is rotated by the conveyor belt 100 'contacting the upper side in an inclined state as the meandering end is displaced in the g direction and the opposite end of the meandering direction in the g' direction. When the meandering adjustment roll 68 takes such a state, the meandered conveyor belt 100 'is moved in the direction of A "to travel in the normal state.

Meanwhile, even when meandering occurs in a direction opposite to that of FIG. 9, as shown in FIG. 10, the meandered conveyor belt 100 ′ is adjusted to the normal conveyor belt 100 through the same process as in FIG. 9.
