DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical belt conveyor, and more particularly, to a vertical belt conveyor which prevents belt deposits from falling during a return stroke.

[0002]

2. Description of the Related Art Conventionally, a vertical belt conveyor has been used as a device for mainly transporting bulk materials such as coal, limestone, iron ore and wood chips in a vertical direction. This vertical belt conveyor is driven by two endless belts 3 and 4 wound flatly around two sets of a driving drum 1 and a driven drum 2 arranged at a predetermined interval, as shown in FIGS. 5 and 6, for example. The endless belts 3, 4 are arranged vertically with the drum 1 upward, and the upside outer surfaces 3 a, 4 a of the endless belts 3, 4 are overlapped with each other to form a vertical luggage transportation process B. Among the endless belts 3 and 4 separated from each other at the lower part of B, one endless belt 3 is extended in the lateral direction to form a luggage placing section A,
Further, one of the endless belts 3 and 4 separated from each other at the upper part of the baggage carrying process B has a configuration in which one endless belt 4 is extended in the lateral direction to form a baggage discharge section C, and the endless belts 3 and 4 are provided.
Is driven and circulated to transport the luggage 5 such as loose objects placed in the luggage placement section A upward through the luggage transporting step B and discharge it through the luggage discharge section C.

[0003] Such a vertical conveyor is very convenient because the bulk material can be conveyed in the vertical direction as it is with a simple structure. In addition, since the bulk material is sandwiched between the endless belts 3 and 4 and is conveyed upward, it is used. In addition, there is no fear that the bulk materials, crushed debris and powder adhering to them fall or scatter in the middle of transportation, and this is excellent in terms of environmental hygiene.
However, the return strokes D and E of the endless belts 3 and 4 are driven in a state where the load side is exposed. Therefore, the powdery material generated from or interposed between the loose materials adhering to the belt surface is naturally returned in the return strokes D and E, or by the support roller in contact with the belt surface, Falling due to vibrations caused by driving
Scattering and contaminating the surroundings will cause environmental degradation,
There was a problem.

[0004] In particular, the vertical conveyor has a large influence on the surroundings because the return strokes D and E are extended in the vertical direction.

[0005]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is that a conventional vertical conveyor is
The point is that the particulate matter generated from the loose substances adhering to the belt surface falls and scatters in the return processes D and E, contaminates the surroundings, and deteriorates the environment.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a vertical luggage carrying process in which two rising end surfaces of two endless belts arranged in a vertical direction overlap with each other and move upward with luggage therebetween. And a vertical belt conveyor in which one of the two endless belts separated from each other at a lower portion and an upper portion of the vertical baggage carrying process has a laterally extending baggage loading section and a baggage discharging section, respectively. In the return stroke, at least in the vertical section on the descending side, the endless belt is rolled and advanced in the shape of a pipe, thereby preventing falling and scattering of the surface deposits on the endless belt in the return stroke. To achieve the purpose of providing a vertical conveyor.

[0007]

The endless belt is rolled into a pipe shape with the luggage-loading side inward in the return stroke and is advanced, so that the adhered matter on the surface of the endless belt in the return stroke is prevented from dropping and scattering.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIGS. 1 and 2 show an embodiment of the present invention, in which two sets of a driving drum 1 and a driven drum arranged at predetermined intervals. The two endless belts 3 and 4 wound around the endless belt 2 are arranged vertically with the drive drum 1 upward, and the rising outer surfaces 3a and 4a of the endless belts 3 and 4 exhibiting a flat state. A vertical luggage carrying process B is formed by overlapping with each other, and one of the endless belts 3 and 4 separated from each other at a lower portion of the luggage carrying process B is extended in a laterally flat state to be relatively long. A flat luggage placing section A is formed, and one endless belt 4 of the endless belts 3 and 4 which are separated from each other at the upper part of the luggage carrying process B is extended in a laterally flat state to form a luggage discharge section C. doing.

The endless belts 3 and 4 have return strokes D and E
Of these, the vertical section on the descending side where the adherence on the belt surface is likely to fall or scatter, especially because of the long distance or the structure in which the supporting roller is in contact with the load-bearing side of the belt 6, 7 and the lateral section 8 of the endless belt 3, the baggage is rolled forward with the luggage-loading side being inside.

A support roller 9 for supporting the flat portions of the endless belts 3 and 4, a shape-retaining roller 10 for rolling and holding the pipe shape, a rounding device 11 for rolling the flat shape into a pipe shape, and a pipe shape As the developing device 12 for developing the flat state from the ground, a conventionally well-known structure can be used as it is.

In this embodiment having the above structure, the endless belts 3 and 4 are driven and circulated, and the load 5 placed on the load placing section A is moved upward by the load transporting process B, similarly to the conventional vertical belt conveyor. And discharged through the baggage discharge section C.

In the drawings, reference numeral 13 denotes an endless belt 3,4.
This is a collector for preventing the scatter of attached substances that are dropped when the pipes are expanded from the pipe shape into a flat state.

In this embodiment, of the return stroke D of the endless belt 3, the descending vertical section 6 and the transverse section 8 of the endless belt 4 and the descending vertical section 7 of the return stroke E of the endless belt 4.
Because the baggage is configured to be rolled into a pipe shape with the baggage loading side inside, the endless belt 3, while carrying the baggage,
There is no concern that the powdery or particulate matter generated from or interposed between the loose substances attached to 4 will not fall or scatter and will deteriorate the surrounding environment.

FIG. 3 shows a different embodiment of the present invention. The whole structure is almost the same as that of the above-mentioned embodiment. Among the endless belts 3 and 4, one of the endless belts 3 is formed by extending one endless belt 3 in the lateral direction in a flat state, and a flat luggage placing section A is short, and the endless belts 3 and 4 are separated from each other at an upper part of a luggage transporting process B. A load discharge section C formed by extending one endless belt 4 in a laterally flat state is formed to be relatively long.

Therefore, in the return stroke D of the endless belt 3,
Return stroke E of the descending vertical section 6 and the endless belt 4
In the vertical section 7 and the horizontal section 14 on the descending side, the baggage is configured to be rolled into a pipe shape with the luggage-loading side as the inside, and the powder particles adhere to the endless belts 3 and 4 fall and scatter. Is effectively prevented.

FIG. 4 shows still another embodiment of the present invention, in which almost all sections of the return strokes D and E of the endless belt 3 are rolled up in a pipe shape with the luggage-loading side inward. It is composed. Therefore, it is possible to reliably prevent the powder or particles attached to the endless belts 3 and 4 from falling or scattering.

As described above, the present invention can be applied to various types of vertical conveyors, and the vertical travel within the return strokes D and E of the endless belts 3 and 4, which are an essential component of the vertical conveyor. For sections 6 and 7, it is only necessary to roll the pipe into a pipe shape with the baggage-loading side inside, and for the rest of the return steps D and E, the type of baggage to be conveyed in accordance with the format. It is only necessary to form a pipe-shaped portion appropriately in accordance with the nature of the object and to efficiently prevent the attached matter from falling and scattering.

[0018]

According to the present invention, the two endless belts constituting the vertical belt conveyor are formed into a pipe shape at least in the vertical section on the descending side, with the luggage-loading side being inside, and being advanced. I made it. Therefore, it is possible to prevent the deposits on the surface of the endless belt from falling and scattering in the return stroke, and it is possible to prevent the surroundings from being polluted and the environment from being deteriorated.
