The present invention relates to a device for preventing a package, such as coke, from falling on the inclined portion of the belt conveyor, more specifically, a small amount of the package in the belt conveyor device formed with a large transport inclination angle through the tail portion chute carrier belt In the case of dropping on the upper part of the belt, the package is prevented from falling down by the belt elasticity of the rubber material, and returned to the tail part, and then falls to the lower part of the belt. will be.

In general, as shown in FIG. 1, the belt conveyor 200 is rotated while the belt 210 made of rubber material is caught in an endless track between the driving pulley 212 and the driven pulley 214, and at one side thereof. The tension adjusting device 220 is provided to maintain a constant tension on the belt 210.

The belt conveyor 200 has a carrier belt 230 side on which the package L is loaded and a return belt 240 side opposite to the carrier belt 230, and a package L on one side of the carrier belt 230. The tail chute 232 carrying the bag is formed and the belt conveyor 200 transfers the package L dropped on the belt 210 therefrom.

However, such a belt conveyor 200 has an inclination formed on the side of the carrier belt 230 where the chute 232 is located, in particular, the inclination angle θ is rapidly formed, for example, about 17 degrees or more. At this time, there is a problem that the package L loaded on the belt 210 falls to the bottom of the belt 210.

In particular, when transporting coke with hardness and irregular shape, when the coke is loaded in a small amount, the problems described above occur frequently.

This means that in the case of a package L such as coke, the particles each have an irregular shape, and when they are placed on the belt 210 in large quantities, the lower layer of the package L is applied to the coke particles of the upper layer. It is pressed by the belt 210, the coke particles of the upper layer is supported by the frictional state in a stable state due to the coke particles of the lower layer can be transported as a large amount of package (L) even on the inclined belt (210).

However, if a small amount of coke is put on the belt 210 and this is raised up the inclined portion, these small amounts of coke particles do not adhere to the inclined surface of the belt 210, and the inclined portion of the belt 210 In the problem of rolling down to the lower side due to its own weight.

In this way, the greater the length falling down, the greater the drop speed at the lower part of the inclined portion of the belt, so that it is easily rolled to the side of the belt 210.

If the length of the package rolled up is shortened, the drop speed is very small, so that it does not roll sideways from the belt 210.

However, the conventional belt conveyor 200 does not have any solution.

Therefore, due to the above problems, the productivity of the transportation work is lowered, the reprocessing cost is excessively consumed, and problems such as pollution generation such as polluting the surrounding environment due to Nak coke are frequent.

The present invention is to solve the conventional problems as described above, its purpose is to prevent the phenomenon of rolling by falling down the belt when a small amount of the package having an irregular particle size such as coke during the transport operation to reduce the productivity of the transport operation. To improve, to reduce the cost of reprocessing falling objects, and to effectively prevent the phenomenon of polluting the surrounding environment due to the falling object to provide an improved fall prevention device of the belt conveyor.

In order to achieve the above object, the present invention provides an apparatus for preventing a package, such as coke, from falling in the inclined portion of the belt conveyor,

A plurality of blocking plates arranged to be rotatable in the forward direction of the belt while maintaining a constant distance in the longitudinal direction of the belt at the inclined portion of the belt conveyor;

A load cell configured to detect a weight of a package to be conveyed to the belt conveyor; and operating the cylinder member based on a signal of the load cell to keep the blocking plate horizontal when a package is detected above a preset amount. When the small amount of the package is detected, the control unit is positioned to prevent the package on the belt to fall backward by positioning the blocking plate vertically, including a small amount of the package on the belt is configured to carry without falling By providing a package fall prevention device of the belt conveyor characterized in that.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

As shown in FIG. 2, the apparatus for preventing the dropping of a package of a belt conveyor according to the present invention is paired with the belt 210 interposed therebetween with an inclined portion of the belt conveyor 200. The support plate 5a, 5b for pairing the blocking plate 15 is fixedly installed in an upright structure by the required number so as to maintain the equal spacing in the longitudinal direction of the pair.

Thus paired support (5a) (5b) is three pairs are located in Figure 2, the present invention is not limited to this, the number of the installation can be changed according to the length of the inclined belt 210 Is obvious.

The paired supports (5a) (5b) are each fixedly installed at the same height of the block (7) through a bearing (not shown) in the middle portion, and the first shaft (horizontally connected to the block (7) ( 10) to connect freely.

In the middle of the first shaft 10, the driven cam member 12 is fixed to the first shaft 10 by welding, and the blocking plate 15 is welded in the longitudinal direction of the first shaft 10. As shown in FIG. 2, the structure forms a rectangular hole 17 so that the driven cam member 12 is positioned so that the driven cam member 12 is positioned, and the blocking plate ( 15) is fixedly installed so as to have a structure parallel to the upper surface of the belt (210).

The blocking plate 15 mounts a connecting plate 19 connected to the first shaft 10 and a supporting plate 26 made of reinforced plastic connected to the lower side thereof by using a bolt 24. 26 is formed in a structure having a curvature corresponding to the round surface formed on the upper surface of the carrier belt 230.

In addition, the present invention is a second shaft (30) to be rotatable on the upper end of the support shaft (5a) (5b) in a form parallel to the first shaft (10) on the upper side of the first shaft (10) connected to the blocking plate (15). 30 is mounted, and the second shaft 30 is fixedly connected to the plurality of cam members 32 and 34 by welding.

Such a plurality of cam members are larger in size than those on the other side to form a rope driving cam member 32, and the smaller one on the other side forms the driving cam member 34 to drive the lower side thereof. It is connected to the cam member 12 through the rope 36.

On the other hand, the rope 36 is connected to the driving cam member 34 and the driven cam member 12 as described above, the driven cam member 12 is in a state that the blocking plate 15 is horizontal The horizontally arranged state, the drive cam member 34 is to be connected to each other by fixing the knot in a vertical position. Therefore, these drive cam members 34 and the driven cam members 12 are installed while maintaining their displacements by 90 °.

In addition, the rope driving cam member 32 is to generate the rotation of the upper side second shaft 30, these are a plurality of ropes disposed in the vertical direction of the belt 210 in the longitudinal direction of the rope (40) As shown in Figure 2 through the), to be sequentially connected in the longitudinal direction of the belt 210. Due to this structure, when the rope driving cam members 32 are pivoted about the second shaft 30, they are all equally synchronized with each other through the rope 40. It is rotated through.

On the other hand, the upper side of the rope drive cam member 32 is provided with a power transmission means for rotating them, which is composed of a hydraulic or pneumatically actuated cylinder member 45, the body of the bracket 47 It is fixed to the frame 50, and the rope 55 is connected to the tip of the rod 52. The rope 55 is to be caught along the slide groove of the sheave 60 fixed to the front side of the belt 210, and then connected to the uppermost side of the rope driving cam member 32. .

Due to such a structure, the operation of the cylinder member 45 pulls the rope driving cam members 32 through the rope 55 so that the rope driving cam members 32 interlock through the rope 40. Rotate all through the second shaft 30 of the rotation center, which pulls the rope 36 through the small drive cam member 34 to rotate the driven cam member 12 on the lower side thereof to the center of rotation The blocking plate 15 mounted on the first shaft 10 is to be rotated.

On the other hand, the third shaft 62 to which the sheave 60 is rotatably mounted is located at the front side of the cylinder member 45, and both ends thereof have holes at the ends of the supports 5a and 5b. The bracket 66 is fixed to the structure is installed so that the rotation is made smoothly.

On the other hand, to achieve the operation of the cylinder member 45, a load detection load cell (LOAD CELL) 70 is provided, which is a belt conveyor (before the belt conveyor 200 to which the present invention is applied) is placed ( The weight of the package (L) is mounted on the belt conveyor 200 is mounted to the belt conveyor 200 is equipped with the present invention through the belt conveyor (200).

The load cell 70 transmits the detection signal to the control unit 80 to operate the cylinder member 45 when the control unit 80 transfers the package L under the preset weight.

That is, in the normal transportation operation of the coke, which is the package L, an electrical detection signal of the load cell 70 is applied to the solenoid valves 82a and 82b through the control unit 80, thereby providing the cylinder member 45. The rod 52 is compressed and the rope 55 is pulled by the moving distance of the compressed rod 52 so that the blocking plate 15 is in a state parallel to the upper surface of the belt 210, thereby transporting normal coke. This is done.

However, when the abnormal transfer phenomenon is detected in the load cell 70, as shown in FIG. 3, the blocking plate 15 is extended to the belt 210 by the extension of the rod 52 of the cylinder member 45. It is rotated so as to be perpendicular to the surface to act to block the package (L) on the belt (210).

Referring to the operation and effect of the present invention obtained by the above configuration as follows. As shown in FIG. 2, when the weight of a normal package, for example coke, is detected in the load cell 70, the controller 80 operates the solenoid valves 82a and 82b to operate the cylinder member. As the rod 52 of 45 is compressed by a compression action, the blocking plates 15 are positioned in a structure parallel to the upper surface of the belt 210, and coke is formed on the lower side of the blocking plate 15. It is possible to be conveyed through 210.

If an abnormal transport operation occurs during this normal transport operation, that is, a small amount of coke feed phenomenon (1-5% of the normal transport amount) is detected by the load cell 70, this signal is applied to the controller 80 and the The controller 80 applies a signal to the solenoid valve 82a on the basis of this signal to allow the working fluid to flow into the cylinder member 45 and to discharge the working fluid to the solenoid valve 82b. The rod 52 of the member 45 is extended.

As such, when the rod 52 extends, the length of the rope 55 is increased due to the increased positional movement. The length of the rod 52 is horizontal by the blocking plate 15 due to its own weight as in b) of FIG. Located vertically in the structure.

That is, the driven cam member 12 is converted from the horizontal state to the vertical state by the rotation of the blocking plate 15, which pulls the rope 36 so that the drive cam gear 34 is rotated from the vertical state to the horizontal state. Therefore, the rope driving cam member 32 is also rotated so that the length of the rope 55 pulling along the rotation of the rope driving cam member 32 is allowed as much as the allowable length.

As described above, in the state in which the entire blocking plate 15 has a vertical composition, as shown in FIG. 3, the package L moved in small amounts is integrated on the back of the belt 210 in the traveling direction of the support plate 26. When the inertia force of the package L overcomes the gravity generated by the self-weight of the first blocking plate 15, the package L pushes the first blocking plate 15 upward, and the next time It is moved to the blocking plate 15.

At this time, the maximum height that the first blocking plate 15 is pushed upward by the package (L), if the package (L) is coke, the maximum particle diameter of the coke (75m / m) or less is limited.

As such, the package L passing through the first blocking plate 15 is dropped to the first blocking plate 15 in the process of being moved to the second blocking plate 15 side, but the other part is dropped to the second blocking plate 15 side. It is conveyed with the belt 210. If this package L has an inertia force greater than the weight of the second blocking plate 15, the second blocking plate 15 is pushed up and raised, but if not, the second blocking plate 15 is no longer moved upwards. Without advancing, the first barrier plate 15 rolls to the side.

In this way, the package rolling back toward the first blocking plate 15 is approximately 90 ° with the first blocking plate 15 perpendicular to the top of the belt 210 by the limited clearance length of the rope 55. As shown in Fig. 4, no further angular conversion from the vertical state is possible, so that the movement through the first blocking plate 15 in the reverse direction is prevented and gathered in that state.

Subsequently, when the package L, which is subsequently raised through the first blocking plate 15, is continuously integrated to overcome the gravity of the second blocking plate 15, the second blocking plate 15 is pushed and the third blocking plate ( 15) side is moved upwards, in the process, some will try to roll again to the second blocking plate (15) side. However, since the second blocking plate 15 is not rotated to the opposite side, it is located between the second blocking plate 15 and the third blocking plate 15. And, with the package (L) coming after passing through the second blocking plate 15, the continuous transport action is possible in the belt advancing direction.

As described above, in the present invention, when a small amount of coke is loaded on the belt 210, the blocking plates 15 block the coke from falling down from the belt 210 and accumulate them. Its inertia forces it to pass through the barrier plates 15 in multiple steps. Therefore, even if a small amount of the package (L), the length falling from the belt 210 is maintained by a short distance by the blocking plate 15, so that the phenomenon of falling from the belt 210 is prevented to prevent the surrounding environment It will not pollute.

As described above, according to the present invention, even when the coke is transported by the carrier belt 230 of the belt conveyor having a severe inclination of approximately 17 ° or more, the falling distance falling by the blocking plates 15 formed in multiple stages By keeping it very short it is possible to reduce its fall speed and thus prevent it from falling to the bottom of the belt 210.

Therefore, it is possible to transport the package (L) even in a small amount to improve the productivity of the transport operation, reduce the excessive processing costs incurred during the reprocessing of the transport falling objects, and the falling objects are scattered dust generated in the surrounding workplace By effectively preventing this, useful effects such as eliminating the pollution generating factor can be obtained.
