Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt conveyor, and more particularly to a vertical conveyor belt conveyor.

[0002]

2. Description of the Related Art Conventionally, belt conveyors have been used for continuously transporting a wide variety of powdered materials, granular materials, lumps, earth and sand, semi-fluids such as ready-mixed concrete, and the like, continuously. .

[0003] However, the conveyor belt used for a normal belt conveyor has a smooth surface, and if the inclination is steep, the placed bulk material slides down and cannot be transported.

[0004] For this reason, the vehicle is laid with a gentle inclination, and a large installation space is required in the length direction as a whole.

[0005] Therefore, as a belt conveyor capable of transporting loose materials in a state of being steeply inclined or vertically suspended, a projection such as a partition, a fin or a bucket is attached to the surface of an endless belt or an endless chain. Conventionally, a belt conveyor or a vertical belt conveyor in which two endless belts are overlapped with each other on the ascending side and moved upward with a bulk material interposed therebetween.

However, these belt conveyors cause spillage and scattering of the transported object in the forward and return sections, and it is difficult to use a belt cleaner in the case of a projection provided on the surface. It is unsuitable for transported objects having properties. Further, in the case of a vertical belt conveyor in which two endless belts are stacked, there are problems such as a complicated structure, an increase in the size of the apparatus, and a high manufacturing cost.

In addition, these belt conveyors are configured such that a conveyor belt is wound around a driving pulley and a driven pulley, each of which has a cylindrical shape, arranged at a predetermined interval, and is driven to circulate. Since it is necessary to carry sufficient tensile strength, a rigid core material such as canvas or steel cord is built into the entire belt width and this is covered with rubber material. Since it is extremely difficult to make a turn in a direction, it is used exclusively for straight running and is not suitable for turning.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and a single belt can be used for reliable vertical transportation without requiring a complicated structure and a large volume. In addition, the present invention provides a belt conveyor for vertical transportation that not only can use a belt cleaner and can bend with a small radius of curvature in the horizontal and vertical directions, but also does not cause any spillage or transported objects to scatter or leak. Is what you do.

[0009]

Means for Solving the Problems A conveyor belt for vertical transportation according to the present invention, which has been made to solve the above problems, comprises:
A V-belt in which a band that hardly expands and contracts in the width direction and that easily expands and contracts in the length direction is formed endlessly, and a wire member is embedded inside both sides of the band. Conveyor belts provided with respective ear portions are arranged at intervals in the vertical direction, and have cylindrical grooves formed with circumferential grooves for fitting the ear portions formed of the V-belts on both side ends thereof. A drive pulley and a driven pulley which are wound around the ear portions fitted in the respective circumferential grooves so that a forward path and a return path are formed in a substantially vertical direction, and at least the cylinder in which the forward path is sealed. And a horizontal portion provided with a loading port for an article to be transported is formed at a start end of the outward path.

When the objects to be transported are sequentially loaded from a material loading port provided at a horizontal portion formed at the starting end of the circulating conveyor belt, a portion of the conveyor belt into which the material to be transported is sequentially sealed is a cylindrical shape. And is transported upward through a longitudinally extending forward path, and is discharged from a flatly opened conveyor belt when it is inverted at a winding portion of a drive pulley located at the end of the forward path.

[0011] At this time, the conveyor belt is formed of a strip shape which can be extended and contracted in the length direction and a bendable ear portion, so that the position of the carrier roller arranged on the outward path can be adjusted to be free in the vertical and horizontal directions. You can make it run.

Further, since the conveyor belt hardly expands and contracts in the width direction, the conveyor belt surely supports the transported object, and there is no danger of hanging or expanding between the carrier rollers.

Further, since the conveyor belt has a structure in which a reinforcing wire member is embedded inside the ear portion, the tensile strength is improved.

In addition, since the lugs formed of the V-belts provided along both ends of the conveyor belt are fitted and wound around the belt hooking grooves provided on the driving pulley and the driven pulley, sufficient driving force is provided. Is transmitted.

[0015]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 shows a preferred example of a conveyor belt C used in the present invention. The belt 1 in which the front and back surfaces of a core 2 are covered with cover rubbers 23 and 24 is endless like a conventional conveyor belt. In particular, the core 2 is made of a thick yarn such as a polyvinyl alcohol fiber or a polyester fiber or the like, and a weft 21 made of a fiber having a large tension and a small elongation, and a thin yarn made of, for example, a polyamide yarn. The warp yarn 22 made of a fiber having a high elongation rate such as a fiber is made of a synthetic fiber fabric formed by weaving such that the longitudinal expansion and contraction is increased.
It is formed of a rubber material such as butyl rubber, which has an elongation of 0% or more, a tensile strength of 180 kg / cm ² or more, and excellent physical properties such as wear resistance, weather resistance and ozone resistance. In the length direction, it expands and contracts within a predetermined range with almost no expansion and contraction.

Further, the band body 1 has both side ends 11,
11, ears 12, 12 made of a V-belt are buried in the length direction, respectively.
Reinforcing wire members 13, 13 are buried in the interior of the tube 2 in the longitudinal direction.

As the wire member 13, a steel wire is generally used, and a synthetic rope can be used, and it is used according to the use, the width and length of the belt, running conditions, and the like.

Further, on the back side of the ears 12, 12, a fitting ridge 14 and a fitting groove 15 which can be freely fitted to and removed from each other when the band 1 is rolled into a cylindrical shape in the longitudinal direction. The band 1 is pressed into contact with each other when the band 1 is rolled into a cylindrical shape. Valve members 16 and 17 each having a ridge for preventing ejection are protruded.

FIGS. 2 to 6 show an example of an embodiment of the present invention using the conveyor belt C shown in FIG. 1. The conveyor belt C has horizontal portions at the lower end and upper end of a vertical portion 41. A drive pulley 31 having a tubular shape, which is arranged along a hook-shaped frame 4 in which 42 and 43 are continuously arranged, and which is provided at the upper and lower ends of the frame 4 before and after the hook, respectively. A forward path 5 and a return path 6 are formed by being wound around the driven pulley 32.

At this time, the drive pulley 31 and the driven pulley 32 are formed on the outer peripheral surfaces of the disks 62, 62 (72, 72) provided on both sides of the support shaft 61 (71) as shown in FIG. The V-shaped peripheral grooves 63, 63 (73, 73) are fitted with the ears 12, 12, respectively, made of the V-belt, and at the horizontal part 42 of the frame 4 at the outward path 51, for example, as shown in FIG. The vehicle travels while being changed from a flat shape to a cylindrical shape through an end surface U shape (in the horizontal portion 42, from a cylindrical shape to a flat shape through the end surface U shape) by the disposed guide roller 81.

Further, a pair of guide rollers 81, 81 provided on the bent portions 44, 45 of the frame 4 are attached to both ears 1
2 and 12 are fitted and passed, the ears 12 and 12 are pushed inward each other, and the fitting ridges 14 and the fitting grooves 15 disposed inside and facing each other are engaged with each other. Therefore, the forward path 51 and the return path 52 of the vertical portion 41 are formed in a sealed cylindrical shape.

Further, the conveyor belt C according to the embodiment of the present invention is disposed on the frame 4 because the warp yarns 22 constituting the core 2 are made of fibers having a high elongation and are formed to be stretchable in the length direction. By holding the carrier roller 83 with the carrier roller 83, the vehicle can be run in a state where it is bent in the vertical and horizontal directions with a small radius of curvature of about 5 to 10 times the belt width.

In this case, the minimum radius of curvature could be reduced to about 5 to 10 times the belt width.

Since the weft yarn 21 constituting the core 2 is made of a fiber having a large tension and a small elongation, it hardly expands and contracts in the width direction. No worries or sagging.

Further, in the present embodiment, since the reinforcing wire members 13, 13 are buried inside the ear portions 12, 12, a large tensile strength can be exhibited.

In addition, ears 12 and 13 formed of V-belts provided along both ends of the band 1 are wound around belt-engaging grooves provided in the driving pulley 31 and the driven pulley 32. Therefore, a sufficient driving force is reliably transmitted.

In the present embodiment configured as described above, the horizontal portion 42 (the portion extending from the flat shape to the cylindrical shape through the end surface U-shape) formed at the starting end of the circulating conveyor belt C on the outward path 51 is formed. ) Port 9
When the objects to be transported (not shown) are sequentially charged from the conveyor belt, the portion of the conveyor belt C into which the objects to be transported are charged is sequentially formed into a sealed cylindrical shape, and is transported upward through the vertical portion 41 of the outward path 51. At the time of reversing at the winding portion of the driving pulley 31 located at the end of 51, the driving pulley 31 is discharged from the conveyor belt C which is opened flat. In particular, in the present embodiment, when the conveyor belt C has a cylindrical shape, the fitting ridges 14 and the fitting grooves 15 formed on the ears 12 and 12 are fitted to each other, so that the sealed cylindrical shape is used. It is securely held. Ears 12,
The valve members 16 and 17 formed at 12 are pressed against each other to reliably prevent the transported object from squirting or leaking, and these valve members 16 and 17 are connected to the fitting ridge 14 and the fitting groove of the transported object. Since the attachment to the ridges 15 is prevented, the fitting ridges 14 and the fitting groove ridges 15 always have no attachments and can always form a secure fitting state.

As described above, in the present embodiment, the objects to be transported sequentially input into the object-to-be-transported inlet 9 sequentially push the objects to be transported previously, so that the objects to be transported are continuously fed. It is sent and pushed up even in the sealed cylindrical vertical part 41, and is transported without falling.

In the present embodiment, the transport is performed when the transported object is continuously charged even continuously or intermittently. However, when the loading of the transported material is finally stopped,
If the transported object has low frictional resistance, it is conceivable that the transported object remains in the conveyor belt C. Lastly, a processing object of the residual material formed of a substance having high frictional resistance, for example, an adhesive. To discharge the residue from the conveyor belt C.

When the adherence of the transported object is low and a belt cleaner is not required, the fins or the like are provided on the inner surface of the belt so that the transported object can be left without requiring the processing body. It can be transported to the end without any problems.

[0032]

As described above, according to the present embodiment, vertical transport can be continuously performed over a long distance. In particular, since the belt body that expands and contracts within a predetermined range in the length direction is formed endlessly, it has flexibility, so that it can freely bend vertically and horizontally with a markedly smaller radius of curvature. It can not only perform horizontal bent transportation and up and down inclined transportation, but also vertical,
In both horizontal directions, the direction can be freely changed with a very small radius of curvature. Therefore, a desired route including a vertical portion can be freely determined by one conveyor belt.

Further, according to the present invention, since there is almost no expansion or contraction in the lateral direction, the placed heavy object can be reliably transported without sagging or expanding.

Further, the arrangement of guide rollers and carrier rollers arranged in accordance with the location of music transfer is free and no complicated adjustment is required, so that the structure is simple and the installation and maintenance management are easy.

In particular, since the wire member is buried inside the ear portion, a sufficient tensile strength can be exhibited, and the ear portion for driving and guiding is formed by the V-belt. It can be driven reliably.

Further, the vertical portion is completely sealed,
There is no spillage or scatter of transported objects, and if the return path is completely sealed, the transported objects will not scatter, so it is extremely effective in terms of environmental pollution and can be driven with less power. It is also noise-free and pollution-free.

The present invention has a simple structure, occupies a small volume and is lightweight, and requires no or simple foundation work, and is extremely easy to install and relocate on site.

In addition, it is needless to say that various belt cleaners such as a scraper can be used because no partitions or fins are projected on the inner surface of the belt.

In the present invention, if the transported object does not require a belt cleaner, it is possible to protrude a partition or fins on the inner surface of the belt. It can be transported to the end without using a body.
