The present invention relates to a device for adjusting the meandering of a reversible belt conveyor, and more particularly, in a belt conveyor for carrying ore or other transports, when the belt is operated while the driving direction of the belt is changed in the forward and reverse directions. The meandering device of the reversible belt conveyor has been improved to prevent damage to the belt and the adjacent structure as the transport spills out of the belt due to the meandering of the belt.

Generally, as shown in FIG. 6, the belt conveyor 100 is wound around the roller table 103 on which the carrier roller 101 and the return roller 102 are installed, and the roller members 101 and 102. It is composed of a belt 104 which makes an endless track movement by the power of the motor, and is designed to process a large amount of transport in a short time in transporting coal or ore loaded on the belt 104. In particular, many plants are installed in steel mills. In the belt conveyor 100, the belt 104 is not properly executed by various physical and mechanical factors during the process, and a phenomenon in which the belt 104 is meandered frequently occurs.

In other words, the belt 104 is a meandering motion due to a variety of causes, such as over-transportation of the transport or uneven load attached to the pulley, rollers, etc. At this time, the transport is separated from the belt to the outside and poured out to the outside As the belt is broken or damaged while the facility structures are in contact with each other and the facility structures are in contact with each other, the meandering of the belt 104 is automatically adjusted as an automatic watch roller at any time.

When the belt meandering occurs, the meandering of the belt is controlled using the self-aligning roller. When the belt 104 is biased to the left in the direction in which the belt 104 proceeds, the belt in the opposite direction to be biased is turned by turning the roller to the right. By first contacting the rollers, since the running of the belt is moved to the side where the rollers first contact, the rollers are moved in the opposite direction to which they are biased.

Since the conventional belt meandering operation is made manually, if the degree of meandering or the number of times is too high during the transport of the ore, the manual work must be repeated accordingly, resulting in excessive work time and a decrease in productivity. There was this.

In addition, in the belt conveyor reversible driving in the forward and reverse directions, when the driving meander is adjusted in the forward direction, the meandering of the belt is increased when driving in the reverse direction. Therefore, the meandering direction must be adjusted again in the opposite direction. .

As a conventional technology for solving such a problem, as in the Republic of Korea Utility Model Registration Application No. 1999-22076 shown in Figure 7 (a), when the meandering of the belt 104 detects the meandering with the sensor member 110, the detection By reversing the rack gear 112 by the driving force of the motor 111 actuated by the signal, and changing the position of the guide roller 114 installed in the pinion gear 113 geared thereto by 180 °, It is to adjust the belt meandering regardless of the belt running direction of the belt conveyor 100, but there is a problem that expensive installation cost, a large cost to manage the equipment.

In addition, as shown in the Republic of Korea Patent Application No. 2000-22076 shown in Figure 7 (b), two guide rollers 121 are respectively installed on the left and right ends of the self-aligning return roller 102, the upper return roller 122 By additionally installing), by changing the guide roller 121 in contact with the operation direction of the belt 104 to adjust the belt meandering, which means that the four guide rollers and the rotating portion, the upper return roller, and the stand, respectively There is a problem in that it is additionally necessary to have a complicated structure, excessive installation cost, and impossible to install on a carrier side for easy facility management.

Therefore, the present invention has been proposed to solve the conventional problems as described above, the purpose of which does not need to be artificially operated when the belt meandering, the configuration is simple, low installation, maintenance costs, and operate in the forward and reverse directions By automatically adjusting the meander on the carrier side according to the direction, it prevents the outflow of the ore, and prevents the belt from being broken or damaged the non-structured structure, so as to reduce the cost by prolonging the stable working and equipment life and reducing unnecessary labor. It is to provide a meandering adjusting device for a reversible belt conveyor that can prevent the loss of equipment and manage the equipment reasonably.

As a technical configuration for achieving the above object, the present invention,

 In the belt conveyor that has a roller stand having a plurality of self-aligning carrier rollers in contact with the lower surface of the belt for endless track movement rotatably assembled to the roller table to transfer the goods by reversible operation in the forward and reverse directions ,

The apparatus 1 of the present invention, as shown in Figures 1 to 5 (a) (b), easy to manage the meandering frequently occurs during the operation of transporting the goods using the reversible belt conveyor (100). Regardless of the advancing direction of the belt 104 which is reversible in the forward and reverse directions on one carrier side, the device 1 can be easily adjusted. The apparatus 1 includes a rotating drum 10, a rotating driving part 15, and a rotating driven part 20. Etc.)

Here, the reversible belt conveyor 100 is provided with a plurality of carriers, the return roller 101, 102 to the roller table 104, the belt 104 is wound as in the prior art, the lower portion of the belt 104 A roller stand 106 having a plurality of self-aligning carrier rollers 105 in contact with a surface is rotatably assembled to the roller table 103 to transport the goods on the belt 104.

That is, the rotating drum 10 is in contact with the belt 103 that meanders due to various causes during transport of the transport, that is, the right end of the belt 103 when meandering, and the belt 103 when left meandering. Cylindrical members are respectively installed on the left and right sides of the roller stand 106 so as to be rotated in one direction by the driving force of the belt 103 to the endless orbital movement by the driving force of the motor not shown when the left end of the contact. .

The rotating drum 10 has a cylindrical drum body 11 having a drum shaft 12, and upper and lower links assembled through upper and lower ends of the drum shaft 12 and bearing members 12a and 12b. The upper link member 13a is assembled to the guide hole 14a of the drum frame 14 vertically installed on the roller table 103, and the lower end of the lower link member 13a is provided. The link member 13b is pivotally assembled via the fixing bar 16 and the hinge shaft 16a of the drum frame 14. Accordingly, the rotary drum 10 receives the traveling force of the belt 104 which proceeds in one direction when contacted with the belt 104 being meandered and rotates in one direction, and at the same time the hinge axis (to the meandering side by the meandering force) It turns to the said drum frame 14 side with 16a) as a pivot axis.

Here, the upper link member 13a includes a first stopper 17a for maintaining the initial state in which the rotating drum 10 is inclined toward the belt 104 by its own weight during normal operation, and excessively of the belt 104. A second stopper 17b for preventing the rotating drum 10 from being excessively pushed toward the drum frame 14 and coming into contact with the drum frame 14 is integrally mounted in a meandering manner.

In addition, between the second stopper 17a of the upper link member 13a and the drum frame 14, a return spring member 18 is provided to smoothly perform the return operation of the rotary drum 10 after meandering adjustment. It is also good to comprise.

In addition, the upper link member 13a is preferably installed to be inclined toward the belt 104 so that the inclined movement is smooth, and the auxiliary link member is connected between the upper and lower link members 13a and 13b. You may also do it.

On the other hand, the rotary driven portion 20 is installed on the left and right ends of the roller stand 106, which is equipped with a plurality of self-aligning carrier roller 105 in contact with the lower surface of the belt 104, and proceeds to the belt (104) The roller by the rotational force generated by contact with the rotary drive unit 15 integrally mounted on the lower end of the drum shaft 12 of the rotating drum 10 so that it can be rotated with the rotation of the rotating drum (10) The meander of the belt 104 is adjusted by rotating the stand 106.

That is, the rotation driven part 20 is composed of an arc-shaped rotating plate 21 mounted on the front surface of the rubber member 22 having a high coefficient of friction, and the rotary driving part 15 in contact with the rubber member 22 to generate a friction force ) Is also made of a material with a high coefficient of friction, such as a rubber member, and on the left and right ends of the rotating plate 21, the third stopper 21a (21b) to prevent the outer drive of the rotary drive unit 15 due to excessive rotation. ), Respectively.

In addition, the rotation driving unit 15 includes a small gear 24a geared with a standby gear 24b so as to reduce the rotation ratio, and a lower end of the rotation transmission shaft 24c on which the standby gear 24b is mounted. The outer circumferential surface may be configured to be in surface contact with the rubber member 22.

The operation of the present invention having the configuration as described above will be described.

A carrier stand 106 having a plurality of self-aligning carrier rollers 105 for contacting the device 1 of the present invention with the lower surface of the belt 104 and rotatably assembled about the stand shaft 106a is provided. In a state in which the roller table 103 is arranged in pairs left and right, when a transport object is normally loaded on the belt 104, the transport operation is normally performed, as shown in FIGS. 3 (a) and 4 (a). As described above, the rotating drum 10 installed on the drum frame 14 via the upper and lower link members 13a and 13b and the hinge shaft 16a may be inclined inward without interference with the belt 104. The state is maintained as it is, and the rotary driving unit 15 at the lower end of the rotary drum 10 also maintains the initial state spaced apart from the left and right ends of the carrier stand 106 at a predetermined interval.

In this state, as shown in FIG. 3 (b), the belt 104, which normally proceeds in one direction, meanders to the left in one side due to various causes, and the left end of the belt 104 is rotated. When the drum body 11 comes into contact with the outer circumferential surface of the drum 10, the rotating drum 10 which is stopped starts to rotate clockwise and at the same time, the rotating drum 10 is hinged by a belt 104 that meanders laterally. The shaft 16a is pivoted toward the drum frame 14 with the pivot axis.

On the other hand, the rotary driving unit 15 opposite to the upper end of the drum shaft 12 of the rotary drum 10 is mounted to the left end of the roller stand 106 while being away from the drum frame 14. It turns to (20) side.

At this time, the rotating drum 10 which is rotated laterally at the same time as the rotation of the belt 104 by the meandering force, the second stopper 17b installed on the upper link member 13a comes into contact with the drum frame 14 first. By stopping the further lateral turning movement to prevent the interference with the drum frame 14, to have an inclined state that can be returned to the initial state by its own weight when the meandering adjustment is completed.

On the other hand, when the rotary driving part 15 moved to the rotary driven part 20 by the side turning of the rotary drum 10 is in contact with the rubber member 22 of the rotating plate 21 to induce friction, the rotation Since the rotational force of the rotary drive unit 15 rotating together with the drum 10 is transmitted to the rotating plate 21, the roller stand 106 on which the rotating plate 21 is mounted is right-sided with respect to the stand shaft 106a. The right side of the belt on the opposite side of the left side where the meandering of the belt 104 occurs while rotating to the first and the carrier roller mounted on the right side of the drawings among the plurality of self-aligning carrier rollers 105 installed on the roller stand 106 Contact. Accordingly, the meandering of the belt 104 is adjusted correctly so that the belt center gradually coincides with the center of the roller stand 106.

Then, when the meandering of the belt 104 is correctly corrected so that the meandering adjustment is completed and the belt 104 and the rotating drum 10 are spaced apart from each other, the rotating drum 10 is moved from the drum frame 14 to the belt ( While turning to the initial state about the hinge shaft 16a by its own weight to the 104 side, the rotary drive unit 15 mounted on the lower end of the drum shaft 12 of the rotating drum 10 is turned in the opposite direction to the above. It is returned and spaced apart from the rubber member 22 of the rotating plate 21. At this time, the rotating drum 20 is tilted by its own weight until the first stopper 17a of the upper link member 13a is stopped by interfering with the drum frame 14. Accordingly, the belt 104 is automatically switched to a standby state capable of adjusting the meandering again when the belt 104 is meandered again.

On the other hand, it can be seen that the transport path of the object is reversed and the advancing direction of the belt 104 is reversed to adjust the meandering occurring during the progress of the belt 104 as described above.

Therefore, according to the present invention having the configuration as described above, by transmitting the rotational force of the rotating drum rotated in contact with the belt proceeding meandering when the belt meander occurs, the rotating plate mounted on the left and right ends of the roller stand, Rotate the roller stand with the carrier roller in the meandering direction, contact the opposite side of the belt where the meander occurs and the carrier roller first to adjust the belt meander correctly.After the meandering correction, the rotating drum and the rotary drive part return to the initial state by their own weight. As a result, the meandering of the belt can be continuously adjusted during the transport of the consignment, and the simple structure has the effect that the maintenance of the equipment can be saved and the work productivity can be improved.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to clarify that knowledge is easy to know.
