Description

Raw material packing device {DEVICE FOR COVERING RAW MATERIALS}

The present invention relates to raw material facility. More specifically, the present invention relates to a yard raw material packaging device that can be more conveniently and conveniently performed to cover the yard raw material.

In general, various ores and coals from different origins are deposited in the yard by raw material processing facilities. Since the raw materials deposited in the yard are exposed to the outside, they are blown into the wind to generate fine dust, causing environmental pollution. In addition, when the rain comes a lot, the raw material is wet, the raw material is washed off the rain. As a result, raw materials are lost and the cost increases, operation becomes unstable due to clogging of the yard drainage, and the inconvenience of having to dry or dehydrate wet raw materials in a later process.

For example, in the case of coal, when the moisture increases, it is charged into the coke oven, and when the coke is made, the moisture escapes to form a flow path, thereby generating cracks, thereby reducing the strength of the coke. In addition, more heat is consumed to remove moisture, which wastes energy.

Therefore, the raw material deposited in the yard is covered with a packing sheet to protect the fine dust from blowing in the wind or rain.

Conventional packaging sheet installation work is carried out by transporting the packaging sheet to the crane to place along the raw material yard, and more than 10 workers to manually open the packaging sheet to cover the raw material.

However, the conventional structure has a high risk of safety accidents, and the work is difficult and time consuming as the work is performed by hand, resulting in an increase in labor costs. In addition, the removal of the packing sheet is also made by manual work, which is difficult and time consuming, causing trouble in the raw material transfer operation.

The present invention provides a raw material packaging device that can be made easier and more convenient to cover the stacked raw materials with a packing sheet.

In addition, the present invention provides a raw material packaging device that can be more easily performed peeling off the packaging sheet.

To this end, the apparatus includes a packing sheet which is rolled up in a coil form and spreads to cover the raw material loaded in the yard, and a driving unit which provides a driving force for spreading the packing sheet along the loaded raw material,

The packing sheet may be formed with at least one pipeline extending along the unfolding direction at intervals, and the driving unit may include an air line connected to the pipeline and an air pump installed in the air line to supply air. .

Accordingly, when air is supplied to the pipeline, the dried packing sheet is expanded by air pressure to cover the raw material.

The packing sheet may be a structure in which a common pipe communicating with each pipe line is formed at the front end, and an air inlet is formed in the common pipe line so as to be connected to the air line.

The packing sheet may be further provided with a weight on the opposite end of the tip connected to the air line.

The apparatus may further include a return unit for rewinding the unfolded wrapping sheet.

The return unit may include at least one elastic wire installed in the packing sheet and extending along the unfolding direction of the packing sheet to be elastically bent when the packing sheet is unfolded to have elastic return force.

As such, the apparatus mechanically performs the operation of unfolding the packing sheet and the peeling of the packing sheet in the loaded raw material file, thereby making it easier to perform the operation.

In addition, it minimizes the number of workers and reduces the time and effort required for work, improving workability and lowering labor costs.

According to the above drawings, the present packaging device 10 is rolled in a coil form and unfolded to wrap the packaging sheet 20 covering the raw material pile P loaded in the yard (G), and the raw material loaded with the packaging sheet 20 It includes a driving unit for providing a driving force for unfolding along.

The packaging sheet 20 is prepared in a coiled state, and is placed along one side of the piled raw material pile P along the longitudinal direction. The packaging sheet 20 is formed to have a length corresponding to approximately the length of the raw material pile (P).

As shown in FIG. 2, the packing sheet 20 is formed with at least one pipe line 22 extending along the unfolding direction at intervals.

The conduit 22 is formed between the front side 21 and the rear side 23 of the packing sheet 20. That is, in the present embodiment, the packaging sheet 20 is formed of a double-sided structure of the front surface 21 and the rear surface 23, and the packaging sheet 20 is attached with a space between the front surface 21 and the rear surface 23. It forms one conduit 22 extending in the unfolding direction of. Of course, in addition to the above-described structure, a separate pipe line 22 may be a structure attached to the packing sheet 20, and is not particularly limited. The front surface 21 and the rear surface 23 of the packaging sheet 20 are made of a material that can withstand air pressure sufficiently without air escape.

In this embodiment, the driving unit may have a structure in which the conduit 22 is expanded using high pressure air. To this end, the driving unit includes an air line 30 connected to the conduit 22 and an air pump 32 installed in the air line 30 to supply air.

Accordingly, when air is supplied to the conduit 22, the packaging sheet 20, which is dried while the conduit 22 is expanded, is expanded along the raw material pile P by the air pressure of the conduit 22 to cover the raw material.

On the other hand, the packaging sheet 20 is provided with a return unit for rewinding the unfolded packaging sheet 20 when the air pressure is removed. The return unit is installed in the packing sheet 20 and extends along the unfolding direction of the packing sheet 20 to be elastically bent when the packing sheet 20 is unfolded to have at least one elastic wire 40 having elastic return force. It includes.

The elastic wire 40 may be formed of a shape memory alloy material for storing the original state in which the packaging sheet 20 is rolled in the form of a coil. The elastic wire 40 can be applied to any material that can be elastically bent in addition to the shape memory alloy material to apply the elastic return force to the packaging sheet 20.

As shown in FIG. 2, the elastic wire 40 is attached between the front side 21 and the rear side 23 of the packing sheet 20. For example, the front face 21 and the rear face 23 may be attached at intervals to form a long extending pocket, and the elastic wire 40 may be inserted into the pocket.

In the present embodiment, the elastic wire 40 and the conduit 22 are configured to be alternately arranged along the packaging sheet 20. In another embodiment, the elastic wire 40 and the conduit 22 may be disposed only at both front ends along the unfolding direction of the packing sheet 20. The number and installation positions of the elastic wire 40 and the conduit 22 are not particularly limited.

As shown in FIG. 2 and FIG. 3, in order to connect the pavement sheet 20 and the air line 30, a common conduit 24 through which each of the conduits 22 communicates with a tip of the pavement sheet 20. Is formed. In addition, at least one air inlet 26 is formed in the common pipe 24 to be connected to the air line 30. A connection socket 28 is installed between the air inlet 26 and the air line 30.

The air supplied to the air line 30 is injected into the common pipe line 24 through the air inlet 26, is distributed to each pipe line 22 in communication with the common pipe line 24 to separate each pipe line 22 Inflated.

In addition, as shown in Figure 3, the weight 50 is further installed on the inner end of the wrapping sheet 20, that is, the opposite end of the tip connected to the air line 30.

The weight 50 serves as a weight so that the packaging sheet 20 can be bent downward when the packaging sheet 20 is over the top of the raw material pile (P). The weight 50 is provided with a plurality of intervals along the tip of the packaging sheet 20. The weight of the weight 50 is set at such a degree that the packing sheet 20 can move upward along the raw material pile P when air pressure is applied to the pipe line 22, and is not particularly limited.

Hereinafter, the operation of the apparatus will be described with reference to FIG. 4.

The packing sheet 20 is prepared in a state of being wound in a coil form. The packing sheet 20 is placed along one side end of the pile raw material pile P by a crane or a vehicle.

In this state, to expand the packing sheet 20 to cover the loaded raw pile, the air line 30 is connected to the air inlet 26 at the tip of the packing sheet 20, and the air is simply supplied. 20) can be opened.

That is, when the air pump 32 is driven, air is supplied through the air line 30, and the supplied air is injected into the common pipe 24 of the packing sheet 20 through the air inlet 26.

The air supplied to the common pipe 24 is distributed into each of the pipes 22 communicating with the common pipe 24. Accordingly, the pipe 22 is inflated and expanded by the pressure of the air supplied thereto.

The conduit 22 is formed along the unfolding direction of the packing sheet 20, so that the conduits 22 expand in a straight line as each conduit 22 expands due to air pressure. As the conduit 22 is straightened by air pressure, the wrapped packing sheet 20 is unfolded by the pressure of the conduit 22. Therefore, the packing sheet 20 continues to spread out and goes toward the top of the raw material pile while covering the raw material file along the upwardly inclined side of the raw material pile P.

When the packing sheet 20 being unfolded and moved by air pressure passes through the top of the raw material pile P, the packing sheet 20 is moved downward by the weight of the weight 50 installed at the tip of the packing sheet 20 and the packing sheet 20. It will be bent.

The packaging sheet 20 is unfolded while being unfolded along the downwardly inclined side of the raw material pile (P) to cover the opposite side of the raw material pile.

In this way, the device can only cover the raw material pile P by expanding the packing sheet 20 by supplying high-pressure air.

On the other hand, as the packaging sheet 20 is rolled up as described above, the elastic wire 40, which is rolled up like the packaging sheet 20, is stretched in a straight line. Accordingly, the elastic wire 40 is elastically curved while being stretched in a straight line.

Therefore, when the air supplied in a state in which the packaging sheet 20 is expanded to cover the raw material pile, the packaging sheet 20 may be returned to its original state and the packaging sheet 20 may be peeled off from the raw material pile.

When the air pump 32 is driven or the valve is opened, the air supplied to the packaging sheet 20 through the air line 30 is discharged to the outside.

As a result, the air on the conduit 22 of the packing sheet 20 escapes, and the pressure of the conduit 22 with respect to the packing sheet 20 is removed while the conduit 22 that has been expanded by the air pressure returns to its original state.

The packing sheet 20 from which the pressure in the conduit 22 is removed is subjected to the elastic return force of the elastic wire 40. Therefore, as the elastic wire 40 is bent in the original state, the wrapping sheet 20 in which the elastic wire 40 is installed is also bent in a coil form while being bent like the elastic wire 40.

Here, the above process is made from the front end of the packing sheet 20, that is, the end on which the weight 50 is installed. In this process, the weight 50 may be removed so that the packing sheet 20 can be more easily wound.

As the air continues to escape, the packing sheet 20 is continuously wound by the elastic force of the elastic wire 40 and returns to its original position through the top of the raw material pile P. By removing the air supplied in this way, the packing sheet 20 can be easily peeled from the raw material pile.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course.
