Description

Transportation equipment and transport method {CONVEYOR EQUIPMENT AND TRANSPORT METHOD}

The present invention relates to a transport facility and a transport method, and more particularly, to a transport facility and transport method capable of restraining an object from being loaded with bias.

The transport facility is a belt that circulates in the form of a closed loop, each of which is formed to extend in the width direction of the belt, is rotatable in a state in which the belt is supported on the top, and a plurality of carrier rollers arranged in the direction of movement of the belt and each It is formed to extend in the extending direction of the carrier roller, and is rotatable in a state in which the belt is supported on the upper portion, and includes a plurality of return rollers arranged in the moving direction of the belt.

Hereinafter, for convenience of description, among belts, a belt region positioned on the upper side and supported by the carrier roller is called a carrier belt, and a belt region positioned on the lower side and supported by the return roller is called a return belt.

Using the transport equipment as described above, transported materials such as ore, coal, coke, and the like (hereinafter, to-be-processed objects) are loaded and transported on a carrier belt. Alternatively, depending on the state of the transportation facility, a meander may be generated in which the belt is biased to either one of both sides in the width direction.

When the meandering of the belt occurs, knitting is generated in which the object to be processed is not loaded on the central portion of the belt and is driven to the left and right sides of the belt. Due to this, the object is dropped to pass through the chute and the object to be treated is loaded in the yard, whereby a large amount of object to be treated is loaded. Accordingly, a meander prevention device for preventing meandering of the belt is separately installed in the transportation facility.

Conventional meandering prevention device is a rotating roller, a rotating stand positioned on the lower side of the rotating roller, a rotatable stand rotatable about the center of the extending direction, and a rotating stand connected to the rotating stand so as to be rotatable about the center of the extending direction The member includes first and second guide rollers located on both sides of the rotational roller in the extending direction from the front or rear of the rotating roller.

Hereinafter, the operation of the meander prevention device will be described.

When the return belt is skewed to be biased to either side, for example, it is in contact with the first guide roller positioned in one direction of the return belt. Then, the first guide roller rotates while maintaining contact with the return belt. Due to this, the rotating stand connected to the first guide roller is rotated around the rotating member so that it is level. At this time, due to the surface frictional force between the rotating roller and the return belt, the force is applied in the opposite direction to the direction in which the return belt is meandered, and in other words, it is returned to travel in a normal path so as not to bias.

However, when the belt ages and the lower surface of the belt ages, or when the frictional force of the belt decreases due to moisture penetration, the frictional force between the rotating roller and the return belt decreases. Accordingly, the rotation of the rotating roller is insufficient or the belt may be meandered because it is not rotating. In addition, it may be difficult to return the meandering belt to run on a normal path.

In addition, since the belt has flexibility, the return belt may be bent when one side of the return belt is in contact with the guide roller. When one side of the return belt is bent so as to protrude to the upper side of the guide roller, this bending causes There is no effect due to the operation of the meander prevention device. That is, even if the meandering prevention device operates properly, the belt may not return to be meandered and run on a normal path.

A plurality of such carrier rollers 30 are provided and are formed to extend in the extending direction (X-axis direction) of the frame 20 or in the extending direction (X-axis direction) of the carrier belt CB.

As described above, the carrier roller 30 is inclined upward in both directions from the center of the extending direction, and the carrier belt CB moves in a state where its lower surface is supported by the carrier roller 30. Thus, the carrier belt (CB) is a center of the direction (ie, the width direction or the Y-axis direction) that intersects with the extending direction, and becomes a recessed shape. Since the object to be processed is loaded, for example, the carrier belt (CB) It is possible to load more stably than when it is flat in the width direction.

The carrier support device 40 is formed to extend in the extending direction of the carrier roller 30 and is formed to extend in the vertical direction of the carrier support 41 installed on the upper side of the frame 20 and one end is connected to the carrier support 41 , The other end is connected to the carrier roller 30, and includes a carrier stand 42 supporting the carrier roller 30 to be rotatable.

The return roller 50 is located under the carrier roller 30 and the frame 20, and is rotatable by the moving force of the belt B according to the operation of the pulley 10. The return roller 50 is formed to extend in the extending direction (Y-axis direction) of the carrier roller 30, and is formed horizontally without being inclined unlike the carrier roller 30. A plurality of such return rollers 50 are provided and arranged in the extending direction (X-axis direction) of the frame 20 and the belt B.

The return stand 60 is formed to extend in the vertical direction (Z-axis direction), one end is connected to the frame 20, the other end is connected to the return roller 50, and supports the return roller 50 to be rotatable . At this time, the rotating shaft 61 is connected between the return roller 50 and the return stand 60, the return roller 50 may be rotated by the force that the carrier roller 30 moves.

The meandering prevention device A according to the embodiment is a device that suppresses or prevents meandering of the belt B and bending of the belt B.

The meander preventing device A is provided in a pair, and is arranged in the width direction (Y-axis direction) of the belt B, as shown in FIGS. 2, 5 and 6. Then, the pair of meandering prevention devices A are installed to be located outside the width direction of the belt B.

More specifically, one of the pair of meander prevention devices A is located on one side of the belt width B (Y axis direction) passing through the lower path or the return path of the circulation path of the belt B, and the other The opposing side is located on the other side. In other words, one of the pair of meander prevention devices A is located on one side in the width direction (Y-axis direction) of the return belt RB, and the other is located on the other side.

On the other hand, when the return belt RB positioned adjacent to the chute 90 is meandered, the object to be treated is dropped from the carrier belt CB positioned adjacent to the chute 90 to the chute 90, or When the object to be treated of the chute 90 falls to the lower side, it may fall to bias to either side.

This is because the return belt RB disposed adjacent to the chute 90 and the carrier belt CB disposed adjacent to the chute 90 are located close or adjacent.

In other words, meandering of the return belt RB disposed adjacent to the chute 90 means meandering the carrier belt CB disposed adjacent to the chute 90, or the object to be processed on the carrier belt CB When falling into the chute 90, the falling direction is changed to either side.

Therefore, compared to the inlet side flowing into the carrier belt CB so that the object to be treated is loaded on the carrier belt CB, meandering so that the object on the belt is adjacent to the discharge side discharged to the chute 90. The prevention device A is installed. That is, the meander preventing device (A) is to be located in the width direction outside of the belt (B) corresponding to the tail portion disposed adjacent to the chute (90) of the belt (B) supported and transported on the return roller (50) upper portion Install it. In other words, the meander preventing device A is installed so as to be located outside the width direction of the tail portion of the return belt RB.

Since the pair of meandering prevention devices A have the same configuration or structure, in the following description of the meandering prevention device A, one meantime prevention device A will be described.

The meander prevention device A is installed to face the outer surface of the return belt RB, outside the width direction (Y-axis direction) of the return belt RB, and the rotatable side rollers 1000, each return It is located in front of the side roller 1000 to face the belt RB, and spaced apart in the vertical direction with the return belt RB therebetween, and includes rotatable upper and lower rollers 2000a and 2000b.

In addition, the meandering prevention device A includes a roller support device 3000 that can be mounted and detached from the frame 20 while supporting the side rollers 1000 and the upper and lower rollers 2000a and 2000b to be rotatable.

The side roller 1000 is disposed to face or face the side surface of the return belt RB from the rear of the upper roller 2000a and the lower roller 2000b. The side roller 1000 according to the embodiment has a cylindrical shape in which the upper surface and the lower surface are flat, and the outer circumferential surface between the upper surface and the lower surface is curved. That is, the side roller 1000 may have a cylindrical roll shape extending in the vertical direction.

In addition, shafts (hereinafter, first and second side shafts 1100a and 1100b) that are fastened to the roller support device 3000 are mounted to the upper and lower surfaces of the side roller 1000, respectively. That is, the first and second side shafts 1100a and 1100b are connected to the roller support device 3000, and the side rollers 1000 are rotatably connected.

In addition, the side roller 1000 is disposed to be spaced apart from the outer surface of the return belt RB, which is normally operated without being meandered, by 5 mm or more, 30 mm or less, preferably 10 mm or more, and 15 mm or less.

In this way, the side roller 1000 is not skewed, and is disposed at a narrow separation distance of 5 mm or more and 30 mm or less from the outer surface of the return belt RB that is operating normally, so that the return belt RB is twisted excessively or at a large angle. It can be suppressed or prevented. That is, since the side roller 1000 is disposed adjacent to the return belt RB, the meandering movement of the return belt RB can be suppressed by the side roller 1000. Accordingly, the degree of meandering of the entire return belt RB or the belt B can be effectively suppressed compared to a conventional meander preventing device.

Each of the upper roller 2000a and the lower roller 2000b is in a direction crossing the width direction (Y-axis direction) of the return belt RB or the movement direction (X-axis direction) of the return belt RB (Y-axis direction). It is an extended shape. In addition, each of the upper roller 2000a and the lower roller 2000b may have a cylindrical shape in which one end and the other end of both ends of the extension direction are flat, and the outer circumferential surface between the one end and the other end is curved. That is, each of the upper roller 2000a and the lower roller 2000b may have a cylindrical roll shape extending in a horizontal direction (Y-axis direction).

In addition, shafts (hereinafter, upper and lower shafts 2100a and 2100b) fastened to the roller support device 3000 are mounted at one end of each of the upper roller 2000a and the lower roller 2000b, and the other end is a side roller 1000. ) Facing the outer peripheral surface. At this time, as described above, the upper shaft 2100a and the lower shaft 2100b are connected to the roller support device 3000, in a state fastened to the roller support device 3000, the upper roller 2000a and the lower roller ( 2000b) is rotatably connected.

The upper roller 2000a and the lower roller 2000b are spaced apart in the vertical direction, and the spacing is smaller than the height of the side roller 1000 (extended length in the vertical direction), so that the return belt RB can be inserted. It may be greater than or equal to the thickness of the return belt RB.

According to the upper roller 2000a and the lower roller 2000b, even if the return belt RB is meandered at a predetermined angle and a part thereof moves in contact with the side roller 1000, the bending of the return belt RB is conventionally prevented. It can be effectively suppressed or prevented.

That is, when the return belt RB is meandered in the related art and the outer surface thereof is in contact with the guide roller of the conventional meander prevention device, the belt B is excessively bent while being supported on the outer circumferential surface of the guide roller due to the ductility of the belt. It has occurred that overhanging the guide roller has occurred, at least partly protruding upward from the guide roller. In this case, a problem in which the belt is worn and damaged may occur.

However, according to the meander prevention apparatus A according to the embodiment of the present invention, the upper roller 2000a and the lower roller 2000b spaced in the vertical direction based on the return belt RB in front of the side roller 1000. By this, the bending of the return belt RB can be prevented.

That is, when the return belt RB is meandered at a predetermined angle to either side, as shown in FIG. 6, the edge of the return belt RB is inserted into the space between the upper roller 2000a and the lower roller 2000b. And the outer surface moves in contact with the side roller 1000. At this time, since the return belt RB is located between the upper roller 2000a and the lower roller 2000b, bending of the return belt RB can be suppressed or prevented as compared to the prior art.

In addition, the meandering prevention device A according to the embodiment of the present invention does not prevent meandering by using the frictional force between the rotating roller and the lower surface of the return belt, like the conventional meandering prevention device, but instead of the meandering prevention device RB The skew is suppressed by blocking the belt B from being biased to one side through the side roller 1000 disposed adjacent to the outside in the width direction.

Accordingly, even if the belt B ages or the frictional force of the belt B decreases due to moisture or the like, the meandering of the belt B can be suppressed by guiding the outer surface of the belt B regardless of this.

7 is a three-dimensional view showing a second meandering prevention device according to an embodiment of the present invention.

The second meandering prevention device 70 has the same configuration or structure as a conventional meandering prevention device.

Referring to FIG. 7, the second meandering prevention device 70 is formed to extend in the extending direction of the return roller 50 and to extend in the extending direction of the rotating roller 71 to rotate the rotating roller 71 Located on the lower side of the rotating stand 72, which is rotatable about the center of the extending direction, each formed extending in the vertical direction to connect between the rotating stand 72 and the rotating roller 71, rotating roller 71 ) Is a pair of brackets (hereinafter, first and second brackets 73a, 73b) supporting rotatably, extending in the extending direction of the rotating stand 72 to be positioned below the rotating stand 72 Rotation roller (75) connecting the support (74), the rotating stand (72) and the support (74), the rotating member (72) to make the rotating stand (72) rotatable, based on the direction of movement of the turn belt (B) 71) is located in the front, and is located on both sides in the extending direction of the rotating roller 71 A pair of brackets (hereinafter, 3rd and 4th brackets 77a, 77b) connecting each of the second guide rollers 76a, 76b, and the first and second guide rollers 76a, 76b to the rotating stand 72 It includes.

In addition, each of the second meandering prevention device 70 is formed to extend in the vertical direction and spaced apart in the extending direction of the rotating roller 71, one end of which is connected to the frame 20, the other end to the support 74 And connected first and second support stands 78a, 78b.

Each of the rotating roller 71 and the first and second brackets 73a and 73b may be connected to a rotating shaft, and the rotating roller 71 may be rotated by a force that the return belt RB moves.

Each of the first and second guide rollers 76a and 76b may have a cylindrical shape extending in the vertical direction, and rotates in a direction crossing the rotational direction of the rotating roller 71.

The guide rollers 76a and 76b are installed to be positioned in the lateral direction of the return belt RB, as described above, when the return belt RB is not biased or skewed to one side and is moving in a normal path, the guide The rollers 76a and 76b are installed so that the distance from the side surface of the return belt RB is 50 mm or more, more specifically 50 mm or more and 80 mn or less.

When the distance between the guide rollers 76a and 76b and the side surface of the return belt RB is less than 50 mm, when a meander occurs in the return belt RB, the rotating roller 71 rotates around the rotating member. This is because rotation is not easy by the guide rollers 76a and 76b or may interfere with the guide rollers 76a and 76b.

The second meandering prevention device 70 as described above may be installed to be located between the head portion and the installation position of the first meandering prevention device A in the extension path of the return belt RB. In other words, the second meandering prevention device 70 is installed at a position excluding the tail portion.

Hereinafter, the operation of the second meandering prevention device 70 will be described.

More specifically, if the return belt RB is skewed toward one side, for example, while the object is being driven, the first guide rollers 76a and 76b positioned in one direction of the return belt RB Contact. Then, the first guide rollers 76a and 76b rotate while maintaining contact with the return belt RB. Due to this, the rotation stand 72 connected to the first guide rollers 76a and 76b is rotated about a rotation axis, and is leveled.

At this time, due to the surface frictional force between the rotating roller 71 and the return belt RB, the force is applied in the opposite direction to the direction in which the return belt RB is meandered, so as not to be biased in either direction, in other words, the vehicle travels in a normal path. Return as much as possible. In addition, since the return belt RB is in contact with the rotating roller 71, the rotating roller 71, the rotating stand 72, and the first and second guide rollers 76a, 76b also have a direction opposite to the meandering direction. Force acts and rotates.

According to the transportation equipment according to the embodiment, the meandering device of the belt having the side roller, the upper and lower rollers can block or suppress the meandering of the belt, and the warpage of the belt can be suppressed as compared to the conventional one.

That is, even if the belt is skewed, the first meandering prevention device can reduce the meandering degree or angle of the meander by a side roller, and can suppress or prevent the bending of the return belt through the upper roller and the lower roller.

In addition, although the meandering of the return belt can be suppressed or prevented by the first meandering prevention device, for example, when the meandering of the return belt occurs at a position where the first meandering prevention device is not installed, this is the second meandering prevention device described above. It is possible to return the belt to be skewed by the motion of.

Hereinafter, the operation of the transportation facility according to the embodiment of the present invention will be described with reference to FIGS. 1 to 6.

While the object to be processed, for example, is loaded on the carrier belt CB, the pair of pulleys 10 are operated to circulate the belt B in the closed loop direction. At this time, when the object to be loaded on the carrier belt CB is moved to the chute position, it is dropped and loaded downward through the chute.

While the belt B is circulated in the closed loop form, the meander preventing device A according to the embodiment (or the first meandering preventing device A) is prevented from being excessively meandered or prevented from being meandered by the return belt RB. Do not.

For example, when the return belt RB is meandered in one direction of one of the width direction and the other direction, the return belt RB has one edge in the width direction of the upper roller 2000a of the meander prevention device A And the lower roller 2000b. Then, when one side of the meandering return belt RB comes into contact with the outer circumferential surfaces of the side rollers 1000 located at the rear of the upper roller 2000a and the lower roller 2000b, the meandering is stopped. In other words, the meandering movement of the return belt RB is blocked by the side rollers and is no longer meandering (see Fig. 6).

On the other hand, even if the carrier roller loaded with the object to be processed is not skewed and moved adjacent to the chute, when the return belt disposed adjacent to the chute is meandered, the chute 90 is transferred from the carrier belt CB by meandering of the return belt. ), Or when the object to be treated of the chute 90 falls downward, it may fall to bias to either side.

However, in the embodiment of the present invention, by installing the meander prevention device A at a position adjacent to the suit 90, meandering of the return belt RB disposed adjacent to the suit 90 can be suppressed.

Accordingly, when the object to be dropped from the carrier belt CB to the chute RB, it is possible to pass through the central region in the width direction of the chute 90, and the object to be dropped and loaded under the chute 90 is loaded. It is possible to suppress or prevent the intensive accumulation in either of these.

Further, by suppressing the meandering of the return belt RB, it is possible to prevent a breakage of the side of the belt B due to friction between the belt B and its surrounding structures.

Then, the meandering prevention device A according to the embodiment (or the first meandering prevention device A) is meandering of the return belt RB through the side rollers 1000 located on one side and the other side of the return belt RB. To suppress. In other words, like the conventional meander prevention device 70 (or the second meander prevention device 70), the meandering of the return belt RB is not suppressed by using the frictional force with the lower surface of the return roller 50. . Accordingly, meandering of the return belt RB can be suppressed regardless of the deterioration of the frictional force due to the aging or moisture penetration of the return belt RB.

And, the belt (B) has a ductility, even if the return belt (RB) is in contact with the outer circumferential surface of the side roller 1000, the return belt (RB) does not bend compared to the prior art. In other words, the return belt RB does not bend or bend to exceed the separation distance between the upper roller 2000a and the lower roller 2000b.

Therefore, the phenomenon of riding over the side roller 1000 does not occur so that the side surface of the return belt RB protrudes to the upper side of the side roller 1000, so that the meandering action of the return belt RB by the side roller 1000 does not occur. It can be exercised without this problem.
