Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor for conveying bulk materials such as ores, gravel, mud and grains.

FIG. 14 is a diagram showing an example of a conventional vertical conveyor, and FIG. 15 is a diagram showing another example of a conventional vertical conveyor.

2. Description of the Related Art Conventionally, as shown in FIG. 14, a casing with an intermediate partition plate 311 is used to convey an object to be conveyed, which is made of bulk materials such as ores, gravel, mud and grains, to a predetermined height. An endless rubber belt 33 having a large number of scraping plates 33a is accommodated in 31, and a large number of inner troughs 32 are continuously arranged in the belt 33 so as to be formed between the scraping plates 33a. An object to be conveyed is placed in the inner trough 32, and an input port 3 is formed in the lower portion of the casing 31.
There is known a casing-closed conveyor 30 which is supplied in a form dropped from No. 5 and is discharged along a link orbit of a rubber belt 33 to be discharged from a discharge port 36 formed in an upper portion of the casing 31. ing.
Alternatively, as shown in FIG. 15, a flat belt 39 and a scraper chain 40, both of which are driven to move on an endless track mutually.
In combination with the above, the open type trough 38 formed between the scrapers 40a is made to grip an object to be conveyed between the scraper 40a and the flat belt 39, and the object is conveyed. The conveyor 37, etc. are known.

[0003]

However, since the casing-closed type conveyor 30 shown in FIG. 14 has its entire length covered with the casing 31, a curved line or a variable slope can be formed by using such a conveyor 30. When carrying a certain course or when trying to carry a long distance, it is necessary to design and manufacture the casing 31 which has been hijacked to the curve or the variable slope or the long casing 31 in advance, and which is used. Since the entire conveyor equipment is inevitably fixed, the conveyor equipment becomes very large and impractical. On the other hand, FIG.
The hold vertical type conveyor 37 as shown in FIG.
Although the transfer course can be set so as to follow a variable gradient or long-distance transfer, the transferred object in each open-type trough 38 is at the edge of the scraper chain 40 in the arrow R and S directions in FIG. The formed guide body 41 and the flat belt 3
Since it is constrained only by 9, the flat belt 39 is deformed and cannot be constrained sufficiently when soft dirt or the like having a large specific gravity is the transported object, or
When the bulk material containing powder is the object to be conveyed, there is also a disadvantage that dust is scattered through the space between the guide body 41 and the flat belt 39 during conveyance. Therefore, it has been difficult to obtain a conveyor in which the transport course can be freely set and the type of the transported object does not matter. In view of the above circumstances, the present invention provides a hermetic conveyor capable of carrying a steep slope, a curved line, and a long distance regardless of the type of the transported object.

[0004]

That is, according to the present invention, a belt body (5) formed in an endless annular shape has two shafts (6A), (6).
In a conveyor (2) provided in parallel around B) so as to be rotatable in a rotary manner, a conveyed object loading area (11) is provided on the outer peripheral surface (5b) side of the belt body (5), A pair of engaging parts (5) are provided on both edges (5a, 5a) of (5).

20) have their engaging parts (51, 52), (16, 1)
7) and (19, 20) are engaged with and separated from each other in such a manner that the conveyed object loading area (11) can be closed by engaging with each other. The numbers in () are
It is to be understood that the corresponding elements in the drawings are shown for convenience and therefore the description is not limited to the description of the drawings. below

The same applies to the column of [Operation].

[0005]

With the above-described structure, the present invention acts so that the conveyed article loading area (11) is rotated around the two shafts (6A) and (6B) by the rotation driving of the belt body (5). ..

As described above, each is mounted and supported by the guide frame 23, and is connected and supported by the main frame 22 (shown in FIG. 3) supported by the support legs 21 of the conveyor device 2.

Since the conveyor equipment 1 and the like have the above-mentioned structure, the bulk material 29 such as ore, gravel, mud, grain, etc. is changed from the lowland 3a to the highland 3b in the conveyor equipment 1.
When the sheet is conveyed, first, the support shaft 6B, which is the drive shaft of the conveyor device 2, is rotationally driven in the arrow F direction about the rotation center CT2 as shown in FIG. 2 via the drive device 25. Then, the support shaft 6B rotates the conveyor belt 5 in a shape that is supported in parallel between the support shaft 6B and the support shaft 6A in the direction of arrow K corresponding to the direction of arrow F, and thereby the outside of the conveyor belt 5. In the formed storage portion 11, the belt 5 rolls around the support shafts 6A and 6B in the direction of arrow K, which is a single direction, so that the forward path 2A and the return path 2B that form an endless track are continuously formed. In a circular manner, the outer surface 5b side of the conveyor belt 5 is rotated in the direction of arrow K.
The drive device 25 of the conveyor device 2 can rotate the support shaft 6B in the arrow F'direction to rotate the conveyor belt 5 in the arrow K'direction. As long as it is carried out (unless a malfunction such as the belt 5 being caught in the device 2 occurs), it is rotated only in the direction of arrow K, which is a single direction.

In this way, the conveyor belt 5 of the conveyor device 2 is thus rotated in the direction of arrow K, which is a single direction, and then, as shown in FIG. Or drop it onto the loading section 2
The bulk material 2 is fed to the storage portion 11 by being fed into the storage portion 11 from the arrow A side.
When 9 is loaded and supplied, the bulk material 29 loaded in the storage unit 11 is moved to the arrow K
In the form of being transferred in the direction of the arrow A along the outward path 2A in association with the operation of rotating in the direction, it is conveyed to the carry-out section 28. Therefore, a means for collecting the bulk material 29 from the carry-out section 28 is provided in the highland 3
b or the like so that it is properly installed, or in the form of leaving the conveyor belt 5 to rotate on the end portion of the outward path 2A of the conveyor device 2 in the direction of arrow B.
By means such as free fall from the storage section 11 below the device 2, the bulk material 29 can be unloaded and collected at the carry-out section 28. Further, in the storage portion 11 where the bulk material 29 is unloaded and collected in this way, the conveyor belt 5 supports the support shaft 6
By rotating around B and changing the direction of the rotation to the direction of arrow A, the rotation is moved along the return path 2B,
Since it reaches the loading section 27 again, the bulk material 29 is again set here.
Can be loaded and the bulk material 29 can be repeatedly conveyed in the direction of arrow B via the outward path 2A. Therefore, the loading unit 27
In the above, if the bulk material 29 is continuously loaded and supplied to the storage section 11, the bulk material 29 can be continuously conveyed to the unloading section 28.

By the way, as described above, when the conveyor belt 5 rolls in the direction of the arrow K through the drive unit 25, the belt 5 supports the carrier roller 7, the return roller 9, and the guide roller which support the belt 5. As shown in FIG. 2, the cross-sectional shape, that is, the storage portion 11 is guided by the fixing roller 10, the fastening rollers 12, 13, the release roller 15, and the like.
Change the shape of. First, the conveyor belt 5 extends substantially in the directions of arrows C and D at the end of the outward direction 2A in the direction of the arrow A, which is guided by the outer peripheral surface of the support shaft 6A formed in a cylindrical shape. It has a flat plate shape. Then, as the conveyor belt 5 rolls in the direction of arrow K, at the loading section 27, as shown in FIG. 3, the guide rollers 10 and 10 shown in FIG. 5a is pushed in the directions of the arrows P and P ', and the storage section 11 is gradually adjusted to a shape of a cross-section saucer shape that is open toward the sky, and in this state, the bulk material 29 is stored in the storage section 11. Is an arrow C outside the belt 5,

As shown in FIG. 4, the conveyor belt 5 in this portion is rotated in the direction of arrow K, as shown in FIG. 4, both edges of the belt 5 arranged on both sides in the directions of arrows C and D in FIG. The storage portion 11 is rolled so that 5a and 5a are gradually pushed in the directions of arrows M and M ′ in FIG. Further, as the conveyor belt 5 rotates in the direction of arrow K, as shown in FIGS. 5 to 6, the rotary feed operation of the fastening rollers 12 and 12 and the directions of arrows M and M ′ shown in FIGS. 6 and the rotation feed operation of the fastening roller 13 shown in FIG. 6 and the biasing force toward the upper side of FIG. 6 to guide the engaging grooves formed on both edges 5a, 5a of the belt 5. The engaging protrusion 52 is fitted into and engaged with 51, and is supported by the guide protrusion 53, so that the both edge portions 5a, 5a are fixedly connected to each other as shown in FIG. Then, the storage portion 11 of the conveyor belt 5 to which both edges 5a and 5a are fixedly connected is closed while being surrounded by the belt 5 in an annular shape and having a circular cross-sectional shape. Therefore, if the bulk material 29 is continuously loaded and supplied to the storage portion 11 in the loading portion 27, the bulk material 29
Irrespective of its type and properties, as shown in FIG.
The conveyor belt 5 is tightly constrained by being pressed in the direction of the arrow Q in FIG.

In this way, as shown in FIG. 7, the conveyor belt 5 is connected to the edges 5a and 5a by engaging the engaging groove 51 and the engaging protrusion 52, and the storage portion is closed by this. In the state where the bulk material 29 is firmly restrained and held at 11, the bulk material 29 is transported in the direction of the arrow B of the transport area 26 shown in FIG. 1 by rotating in the direction of the arrow K. Therefore, the lowland 3a where the conveyor equipment 1 is installed
The difference in elevation between the highland 3b and the highland 3b is large, and the transportation area 26 shown in FIG.
Even if the slope has a steep slope, the bulk material 29 retained in the storage section 11 does not slip off from here, and the samurai in a state of being firmly restrained and retained by the conveyor belt 5, all of which are smoothly carried out. It is transported to 28. Further, as shown in FIG. 7, both edges 5a, 5a of the conveyor belt 5 of the storage section 11 located in the transport region 26 are fixedly connected to each other via the engagement groove 51, the engagement projection 52, and the guide projection 53. As a result, the belt 5 is enclosed and closed, so that even if the bulk material 29 contains powder, the powder becomes dust and scatters outside the conveyor device 2. Is prevented.

By the way, in the carrying area 26, both edges 5a, 5a of the engaging groove 51 and the engaging projection 5 are formed in a pair.
When the two are engaged, they are connected as shown in FIG. 7,
As a result, the conveyor belt 5 that occludes and surrounds the storage portion 11 in a circular cross section surrounds the end portion in the arrow A direction, which is the entrance portion of the carry-out portion 28, as the belt 5 rolls in the arrow K direction. 8, as shown in FIG. 8, the engaging grooves are guided by the rotational feed operation of the release rollers 15 and the urging force in a direction projecting to the front side of the paper surface in FIG. The engaging projection 52 is disengaged, that is, the guide projection 53 is disengaged, that is, separated, so that the storage portion 11 in the carry-out portion 28 is opened again toward the sky. .. Therefore, in the carry-out section 28, the bulk material 29 can be easily unloaded and collected from the storage section 11. The conveyor belt 5 after the bulk material 29 is collected and discharged from the storage unit 11
Is substantially extended again in the directions of arrows C and D while being guided by the outer peripheral surface of the support shaft 6B having a cylindrical shape at the base point portion of the return path 2B which is the end point portion of the outward path 2A shown at the end portion in the arrow B direction. It is molded into a flat plate shape, and the return path 2B can be smoothly rotated in the direction of the arrow A while the flat plate shape is maintained. Therefore, only by driving the drive source 25 of the conveyor device 2 to rotate the conveyor belt 5, the engaging groove 51 of the belt 5 and the engaging protrusion 52 are engaged, and thereby the both edge portions 5a, 5a are engaged. The storage portion 11 is disengaged by connecting and closing the storage portion 11 and disengaging the conveyor belt 5 to which the both edge portions 5a, 5a are connected by separating the engagement groove 51 and the engagement protrusion 52. Can be easily released by the rotary motion of the conveyor belt 5 itself, which allows continuous and smooth transportation of the bulk material 29, which is an object to be transported.

By the way, in the above-mentioned embodiment, the conveyor belt 5 has the engaging grooves 51, the engaging protrusions 52 and the engaging protrusions 52 which are engageable and separable from each other in a pair on the both edges 5a, 5a. Although the example in which the guide protrusion 53 is formed to support the belts 52, 52, the belt body such as the conveyor belt 5 is

As shown in FIG. 11, by simply applying an urging force in the M ′ direction (that is, without the aid of the fastening roller 13 shown in FIG. 6), the protrusion 171 is inserted into the recessed portion 161 and the female engagement is performed. By engaging the portion 16 and the male engagement portion 17, both edge portions 5
It is easy to connect a and 5a. Therefore, the structure of the engaging means such as the fastening roller 12 ′ for closing the storage portion 11 of the conveyor belt 5 ′ and the guide frame 23 supporting the same is simplified, and the conveyor device 2 is correspondingly constructed.
It is easy to manufacture and maintain.

Further, as shown in FIG. 12, the belt member such as the conveyor belts 5 and 5'has a concave portion 19 extending in the directions of arrows A and B on one side 5a of both edge portions 5a and 5a. Shaped over its entire length, while both edges 5
As shown in FIG. 13, a protrusion 20 is formed on the other side 5a of a and 5a so as to be engageable with the recess 19 and detachable therefrom.
However, the conveyor belt 5 ″ may be formed so as to extend in the directions of arrows A and B in a pair with the recess 19 to form the conveyor belt 5 ″. Then, FIGS. The conveyor belt 5 ″ shown in FIG. 9 is similar to the conveyor belt 5 ′ shown in FIGS.
In addition to the fact that the pair of recesses 19 and the protrusions 20 that are paired with a can be easily engaged and separated, and the configuration thereof is extremely simple, injection molding or the like for manufacturing the belt 5 ″ is performed. The machining process of No. 1 becomes easier, and the processing accuracy can be improved and the unit cost of the member can be reduced accordingly. The belt body of the conveyor device 2, such as the conveyor belts 5, 5 ', 5 ", can be A pair of engaging portions configured to be engageable and separable from each other is formed on both edge portions 5a, 5a so as to close a storage portion 11 or the like in which a transported material such as a bulk material 29 can be stored. Therefore, it does not matter even if it is formed in the other shape of the above-described embodiment, and therefore, the configuration of the portion other than the both edge portions 5a, 5a in the belt body is also arbitrary, for example, in the outer surface 5b in the embodiment. Concavities and convexities other than those mentioned above may be formed.
