Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to the structure of a conveyor belt used in a conveyor belt having two belts facing each other to sandwich and convey an object. It is something.

<Prior art> Today, various conveyor devices have been developed that can overlap two belts placed opposite each other to sandwich and convey an object. The technique disclosed in the publication is known as a conveyor device capable of conveying objects such as powder particles, agglomerates, or fluids in an inclined manner including vertically.

The technique involves arranging a support belt made of an endless flat belt and a cover belt to face each other, applying tension in the longitudinal direction to these belts, and using this tension to sandwich the conveyed object between the belts. It is constructed so that it can be conveyed at an angle, including vertically.

In the above technology, a smooth conveyance state is maintained by providing curved conveyance sections at the transition section from the horizontal conveyance section to the vertical conveyance section, and at the transition section from the inclined conveyance section to the horizontal conveyance section. It is configured to obtain. The object to be conveyed is conveyed while being held between the support belt and the cover belt from the curved conveyance section through the inclined conveyance section to the curved conveyance section. Further, the inclined conveyance section is usually configured as a straight conveyance section.

<Problems to be Solved by the Invention> In the above-mentioned conveyor device, when an object to be conveyed is held between a support belt consisting of an endless flat belt and a cover belt, the object to be conveyed is a powder such as pulverized coal or grain powder. Alternatively, if the fluid is highly fluid, such as a liquid, it may leak from the overlapping part of the support belt and cover belt formed at the end of the belt.

That is, when two superimposed belts move from a linear conveyance section to a curved section, or from a curved section to a linear conveyance section, or due to vibrations of the conveyor device, etc., the overlapping section at the end of the belt may be damaged. A small gap is generated, and the object to be conveyed is changed in the gripping posture during the conveyance process between the two belts.
Alternatively, it is diffused in the width direction of the belt due to vibrations, etc., and leaks from minute gaps generated in the overlapping portion.

Furthermore, when the conveyed object is a powder, air mixed into the conveyed object when it is sandwiched between two belts is compressed and separated, and the pressure of this air causes the belt to polymerize. If the pressure becomes higher than the pressing force of the two belts acting on the overlapped portion, leakage will occur from the overlapping portion and the conveyed object will also leak at the same time.

As mentioned above, when the support belt and the cover belt are composed of flat belts, it is difficult to bring the belts into complete contact even if the overlapping parts at the ends of these two belts are pressed from the outside. It is.

Further, when the object to be transported is a highly fluid object such as powder or liquid, it is difficult to completely prevent leakage from the polymerization section.

SUMMARY OF THE INVENTION An object of the present invention is to provide a conveyor belt that can prevent an object from leaking between two belts when the object is sandwiched between the two belts and transported.

<Means for solving the problems> In order to solve the above problems, the conhair belt of the present invention has the following features:
It has two belts facing each other in order to grip and convey the object to be conveyed, and at least one of the two belts is provided with a continuous protrusion along the width direction edge. It is something that will be done.

Another conveyor belt is constructed by forming a continuous cavity inside the projection.

Another conveyor belt is constructed by storing a flexible porous material in a cavity provided in the belt.

Other conveyor belts are constructed by forming continuous grooves along the longitudinal direction of the protrusions on the surface of the protrusions provided on the belt, or by pasting fibers on the surfaces of the protrusions.

Other conveyor belts include two belts that are provided facing each other in order to sandwich and convey the conveyed object, and one of the two belts has a continuous belt along the widthwise edge. In addition, the other belt is provided with a groove corresponding to the projection.

Other conveyor belts include two belts that are disposed opposite to each other in order to sandwich and convey the object, and one of the two belts has a flexible belt along the widthwise edge. A plurality of protrusions made of a flexible material are continuously provided, and the other belt has a width that can come into contact with all of the plurality of protrusions along the width direction end portion, and a flexible material is formed to form the protrusion. It is constructed by forming planar protrusions made of a material whose hardness is lower than that of a hard material.

Other conveyor belts include two belts facing each other to sandwich and convey objects, and magnetic materials are attached to the two belts along the widthwise ends. It is composed of

Still another conveyor belt has two belts provided facing each other in order to sandwich and convey the conveyed object, and at least one of the belts has a tip end along the widthwise end. It is constructed by continuously providing fins bent toward the center of the fin.

Effect> According to the above means, continuous protrusions are formed along the widthwise edge of at least one of the two belts that are provided facing each other to sandwich and convey the object. Since we set it up,
When the two belts are superimposed to sandwich the conveyed object,
By creating a bend in the protrusion and closing the gap between the belt and the opposing belt by the bend, it is possible to seal the overlapping portion at the end of the two overlapping belts.

Further, in the case where a void is provided inside the projection, the rigidity of the projection can be made small (by doing so, the bending margin of the projection can be increased, and the sealing performance can be improved).

In addition, when a flexible porous material is housed in the void, it is possible to improve the resilience of the bending that occurs in the protrusion.

Furthermore, when a continuous groove is formed on the surface of the protrusion,
When the two belts are superimposed, the partition wall portions of the grooves individually bend, thereby improving sealing performance.

Furthermore, in the case where fibers are attached to the surface of the protrusions, when two belts are superposed, the pressing force acting on the belts causes the fibers to bite into the opposing belt, thereby improving sealing performance. I can do it.

In addition, if one belt is provided with continuous protrusions along the widthwise edge and the other belt is provided with grooves corresponding to the protrusions, when the two belts are overlapped, the effect will be on the belt. The sealing performance can be improved by firmly interlocking the surface of the protrusion and the groove corresponding to the protrusion by the pressing force.

In addition, one belt is provided with a plurality of protrusions made of a flexible material along the widthwise end, and the other belt is provided with a width that can come into contact with all of the plurality of protrusions along the widthwise end. When the planar protrusions are made of a material with a lower hardness than the flexible material, when the two belts are superposed, the plurality of protrusions are flattened by the pressing force acting on the belts. By biting into the shaped protrusion, sealing performance can be improved.

In addition, if a magnetic material is attached to two belts along the widthwise edges, the sealing performance can be improved by bringing the two belts into close contact with each other due to the adsorption force of the magnetic material when they are polymerized. .

Furthermore, if at least one belt is provided with continuous fins whose tips are bent toward the center of the belt along the widthwise edge, when the two belts are superimposed, the fins will bend toward the center of the belt. Since the bending occurs, the sealing performance can be improved.

<Example> Hereinafter, an example of a conhair belt to which the above-mentioned means is applied will be described with reference to the drawings.

First, a conveyor device in which the above-mentioned conveyor belt is effectively utilized will be explained with reference to the drawings. FIG. 1 is an overall explanatory diagram of the conhair device, and FIG. 2 is an explanatory diagram of the support roller.

The conveyor device shown in Fig. 1 is capable of handling 5 powders such as pulverized coal and grain flour, 1 granules such as salt, sugar, or sand, 1 lumps such as coal or limestone, or fluids such as muddy water, and 1 powder. This relates to a conveyor device for vertically conveying objects, such as objects mixed with lumps, from a low position to a high position.

The conveyor device is composed of an endless belt, and a support belt 1 and a cover belt 2 having a structure to be described later are arranged facing each other so as to overlap with each other, and a cover belt is provided at the contact position of these belts 1 and 2. An opening 3 is formed for receiving conveyed items. This opening 3 is formed by introducing a cover belt 2 in a pattern into a support belt 1 that moves straight so that objects to be transported can be received smoothly.

The support belt 1 is wound between a drive roller 1a provided at a high position, a tail roller 1b provided at a low position, and return rollers lc and ld, and is driven in the direction of arrow a and conveyed. It is configured so that it can be used and returned. Further, the cover belt 2 is wound between a troller 2a provided at a high position, a tail roller 2b provided at a low position, and return rollers 2c and 2d, and is transported together with the support belt 1, Moreover, it is configured so that it can be returned.

The support belt 1 and the cover belt 2 are provided with tension applying mechanisms 4a and 4b provided in the winding path around each roller described above.
A tension of 1.2 in the longitudinal direction is applied by the bell. Due to the action of this tension, when these belts 1 and 2 overlap each other and an object to be conveyed is introduced between the belts 1 and 2, a pressing force is applied to the object to be conveyed, and the friction at this time causes the object to be conveyed to be transferred. It is capable of holding and transporting objects.

The conveyor device includes a horizontal conveyance section 5a extending from a tail roller 1b provided at a low position of the support belt 1 to an opening 3.
A first curved section 5b formed continuously with this horizontal conveyance section 5a, a vertical conveyance section 5C continuous with this first curved section 5b, and a second curved section 5d continuous with this vertical conveyance section 5C. , and a horizontal conveyance section 5e following the second curved section 5d. And the horizontal conveyance section 5a and the first curved section 5
An opening 3 is formed at the connection position with the second curved portion 5.
An open part 6 is formed at the connection position between the horizontal transport part 5e and the horizontal transport part 5e.

In the horizontal conveyance section 5a and the horizontal conveyance section 5e, the conveyed object is conveyed only by the support belt 1, and the support belt 1 and the cover belt 2 are overlapped between the first curved section 5b and the second curved section 5d. With this, the object to be transported is held and transported.

The horizontal conveyance section 5a, the first curved section 5b, and the second curved section 5d
A plurality of support rollers 7 configured as shown in FIG. 2 are arranged in the horizontal conveyance section 5e.

The support roller 7 may be formed by forming the belt 1 into a concave shape as shown in FIG. 2, or by forming the belt 1 into a concave shape as shown in FIG.
As shown in FIG. 1, this is for holding an object to be conveyed between a support bell l-1 and a cover belt 2. Therefore, the support roller 7 includes a roller 7a provided horizontally and a roller 7a provided horizontally.
Two rollers 7b are provided with a predetermined trough angle relative to the rollers 7b.

7C. and each roller 7a
~7C is rotatably supported by a bracket 7e provided on the frame 7d.

The support roller 7 is connected to the horizontal conveyance section 5 as shown in FIG.
a, 5e and the second curved portion 5d are placed on the belt 1 side in order to bend over the support belt 1 and support the load;
Further, the first curved portion 5b is arranged on the belt 2 side in order to support the load applied to the cover belt 2.

Further, a known hopper 8 is provided at a predetermined position upstream of the opening 3 in the horizontal conveyance section 5a. Objects to be transported are supplied and stored in the hopper 8 by a conveyor, a bucket crane, etc. (not shown). The objects to be conveyed accommodated in the hopper 8 are supplied in a fixed amount to the support belt 1 according to the shape of the gate formed in the hopper 8.

In the vertical conveyance section 5C, a plurality of rollers 9 that contact the support belt 1 and the cover belt 2 are arranged in a staggered manner. This roller 9 is rotated as the support belt 1 and the cover belt 2 are conveyed in the direction of arrow a, and presses the overlapping part at the end of the belt 1.2, and also applies a widthwise direction to the belts 1 and 2. This is for applying tension.

In the conveyor device configured as described above, the objects to be conveyed are continuously supplied in a fixed amount from the flopper 8 to the support belt 1 in the horizontal conveyance section 5a, and conveyed to the opening 3. Since the cover belt 2 covers the upper part of the object to be conveyed in the opening 3, the object to be conveyed is held between the belt 2 and the support belt 1 and is transferred from the first curved section 5b to the vertical conveyance section 5C. transported.

In the vertical conveyance section 5C, the overlapping portion of the belt is conveyed while being pressed by the roller 9, and then conveyed to the second curved section 5d. The object transported from the second curved section 5d to the horizontal transport section 5e is transferred to the next process at the terminal end of the transport section 5e.

Next, to explain the support belt 1 and the cover belt 2 in detail, the belts 1 and 2 are overlapped with each other, and the first curved section 5b of the conveyor device is shown in FIG. 3(A), and the vertical conveyance section 5c is shown in FIG. As shown in B), an object to be conveyed is sandwiched between belts 1 and 2, and both ends in the width direction are pressed against each other to form an overlapping portion, thereby conveying the object in a cylindrical shape.

In order to ensure the sealing at the overlapping part, at least one or both of the support belt 1 and the cover belt 2 is coated with the belt 1 as shown in FIGS. 4(A) and 4(B).
．． Along the widthwise end 11.21 of belt 1.2, a protrusion 12.22 is formed which is continuous in the longitudinal direction of belt 1.2. The conveyed object is held in the space 13 formed by the belt 1.2 and the projections 12.degree. 22.

The protrusion 12.22 can be integrally formed with the same material as the belt 1.2, and can also be made of a material 14 that is softer and more flexible than the material of the belts 1 and 2.
It is also possible to form a band-shaped member made of (for example, soft rubber) and adhered with an adhesive.

Further, the protrusion 12.22 may be formed in a rectangular or trapezoidal shape with the upper end portions 12a, 22a formed in a planar shape as shown in FIG. 4(C), but as shown in FIG. 4(D). The upper end portions 12a, 22a may be formed into curved shapes. In particular, when the protrusions 12.22 are formed into a rectangular or trapezoidal shape, it is preferable to form the upper end portions 12a, 22a with a slope toward the inside of the belt.

By forming the upper ends 12a, 22a of the protrusions 12.22 with sloped surfaces in this way, the object to be transported is
2a, 22a, it is possible to prevent the cargo from falling inside the belt and spilling during transport in the horizontal transport section 5a.

Next, as described above, the belt 1.
A case will be described in which the conveyed object is held and conveyed by the conveyor belt 2.

A large tension is applied to the belts 1 and 2 in the longitudinal direction by tension applying mechanisms 4a and 4b.

Due to this tension, a pressing force is generated in the direction in which the belts 1 and 2 come into close contact with each other, and the object to be conveyed is held between the belts by the pressing force. At this time, since the pressing force acts intensively on the protrusions 12.22 formed along the ends of the belts 1 and 2, the upper end 12a of the protrusions 12.22
, 22a are in pressure contact with the surfaces of the belts facing each other, and the protrusions 12.22 are deflected. and protrusion 12.22
The deflection caused by this creates an airtight seal between the opposing surfaces of the belt.

In the above description, the case where the protrusion 12.22 was formed on both the support belt 1 and the cover belt assembly was explained, but the protrusion 12.22 is not necessarily formed on both the belts 1.2.
It is not necessary to form a protrusion on at least one of the belts, and it is possible to sufficiently seal the end of the belt.

[Other Examples]

In FIG. 5, a hollow chamber 14 is formed inside a protrusion 12 provided on the support belt 1, and is continuous in the longitudinal direction of the protrusion 12.

By forming a cavity 14 inside the protrusion 12, the rigidity of the protrusion 12 is reduced, and when the protrusion 12 overlaps and comes into close contact with the opposing cover belt 2, it becomes possible to increase the bending allowance of the protrusion 12. It is possible to improve the sealing performance of the overlapping portion at the end of the belt 1°2.

The shape of the cavity 14 is not particularly limited, and can be formed in a circular, semicircular, or rectangular shape.

FIG. 6(^) shows a cavity 14 formed inside the protrusion 12 in which a flexible porous material 15, such as a sponge, is housed.

In this case, the bending margin of the protrusion 12 can be increased, and the restoring force of the protrusion 12 can be improved when the pressing force acting on the protrusion 12 is released.

FIG. 6(B) shows that the protrusion 1 is formed by superposition with the cover belt 2.
FIG. 2 is an explanatory diagram of a case where bending occurs in 2. As shown in the figure, the support belt 1 and the cover belt 2 overlap, and the ends 11.21 of the belts 1 and 2 are in close contact with each other, and a pressing force is applied to the protrusion 12, causing the protrusion 12 to bend. occurs. Due to this deflection, a part of the protrusion 12 bulges out from the belt 1.2 and also bulges into the space 13, so that the protrusion 12
The upper end 12a of is in close contact with the end 21 of the cover belt 2,
This ensures a secure seal at the overlapping part of the belts 1.2.

In addition, when the conveyed object is pressed by the belt 1.2 and the overlapping part of the belt is completely sealed, the flow of the conveyed object is calmed down. It is expected that there will be areas in the vicinity where the density of objects to be transported is low. In this case, the vicinity of the protrusion 12 becomes a conduction part for the internal pressure, and the internal pressure in the space 13 can be released to the outside through the opening 3 or opening 6 of the conveyor device.

Next, in FIGS. 7(A) to 7(C), a groove 16 continuous in the longitudinal direction is formed in the upper end 12a of the protrusion 12, and a partition wall 17 is formed between the protrusion 12 and the guide 16.

The partition wall 17 formed as described above has low rigidity and therefore has good flexibility, so that a large amount of deflection can be achieved.

When the groove 16 or the partition wall 17 is formed into a rectangular shape as shown in FIG. 7(A), when the tip is formed at an acute angle as shown in FIG. 7(B), or when the tip is formed at an acute angle as shown in FIG. 7(C). It is possible to form it into various shapes, such as when forming it with a curved surface as shown in FIG.

Furthermore, as shown in FIG.
7, it is possible to form a cavity 14 similar to the embodiment shown in FIG. 5 in each partition 17, and furthermore, in the case shown in FIG. It is possible to accommodate a porous material 15 having flexibility similar to that of the above.

FIG. 9 also shows a curved groove 1 in the upper end 12a of the protrusion 12.
6 is formed, and a fin-shaped partition wall 17 is formed on the center side of the belt l by removing the partition wall formed on the outside of the belt l.

By forming such a partition wall 17, the structure shown in FIG. 9 (B
), when the support belt 1 overlaps with the cover belt 2 and the ends 11.21 of the belt are in close contact, the belt l
, 2 are in contact with each other through one partition wall 17, and the surface pressure necessary to seal the overlapping portion to the partition wall 17 can be obtained. Further, since the pressing force acts concentratedly on the partition wall 17, it is possible to cause the partition wall 17 to undergo a large deflection.

Next, in FIG. 10, a fiber 18 such as a canvas core is attached to the upper end 12a of the protrusion 12.

By pasting the fibers 18 in this way, the support belt 1 and the cover belt 2 overlap, and the ends 11, 21 of each other
When the belts 1 and 2 are brought into close contact with each other, the protrusions 12 are deflected and the fibers 18 are bitten into the end portions 21 of the cover belt 2, thereby improving the sealing performance at the overlapping portion of the belts 1 and 2.

Next, FIGS. 11(A) to 11(C) show a case in which continuous grooves 23 are formed in the end portion 21 of the cover belt 2 corresponding to the projections 12 provided on the support belt 1 along the longitudinal direction of the belt 2. It is.

By forming the groove 23 in the end portion 21 of the cover belt 2 in this way, when the protrusion 12 and the groove 23 come into close contact,
It is possible to prevent the belt 1.2 from shifting in the width direction, and it is also possible to cause the partition walls 24 formed between the grooves 23 to be deflected.

Therefore, when the belt) 1.2 is polymerized and the end portions 11.21 are brought into close contact, the bending that occurs in the protrusion 12 and the partition wall 17 formed on the protrusion 12, and the bending that occurs in the partition wall 17 formed on the end portion 21 of the cover belt 2 The synergistic effect with the deflection generated in the partition wall 24 can improve the sealing performance at the overlapping portion.

In each of the above embodiments, the case where the protrusion 12 is formed on the support belt l side has been described, but the protrusion may also be formed on the cover belt 2 side, or it may be formed on both the support belt 1 and the cover belt 2. Of course it is okay to do so.

Next, in FIG. 12, continuous fins 19 are provided along the end portion 11 of the support bell (1).

In this embodiment, four fins 19 are formed at predetermined intervals, and their tips are bent toward the center of the belt 1.

By providing the fins 19, the fins 19 are bent toward the center of the belt 1 when the support belt 1 and the cover belt 2 are superimposed and their ends 11.21 are brought into close contact. When the internal pressure of the space 13 formed by the belt 1.2 increases, the fins 19 are moved by the belt 1.2.
Deflection occurs in the direction of bulging outward. Therefore, the tips of the fins 19 are pressed toward the surface of the cover belt 2 and are crimped, thereby improving sealing performance.

Next, in FIG. 13(A), a plurality of protrusions 24 are formed on the end 21 of the cover belt 2 at predetermined intervals, and a planar protrusion 31 is formed on the end 11 of the support belt 1.

The protrusion 24 is made of a relatively hard material such as hard rubber, and the planar protrusion 31 is made of a relatively soft material such as sponge. Further, the planar protrusion 31 is formed to have a width dimension that allows it to come into contact with all of the protrusions 24 provided on the cover belt 2.

As shown in the same figure (B), the support belt 1 and the cover belt 2
When these are superposed, the protrusions 24 provided on the cover belt 2 abut against and retract into the planar protrusions 31 provided on the support belt 1. At this time, the part of the planar protrusion 31 that comes into contact with the protrusion 24 is compressed, and the protrusion 24 comes into close contact with the support belt 1, so the corresponding contact part is sealed, making it possible to improve sealing performance. It is.

In this example, when calcium carbonate powder having a particle size of 200 m and containing 5% moisture is transported, the powder can be transported without leaking from the overlapping part at the widthwise end of the support belt 1 and the cover belt 2. was completed.

Next, in FIG. 14(A), a protrusion 12 having a cavity 14 similar to the embodiment shown in FIG. At the same time, a cavity 33 is also formed in the end portion 21 of the cover belt 2, and the cavity 33 is filled with ferromagnetic powder 34. In the same figure (B), a magnetic plate 35 such as an iron plate is embedded in the end 11 of the support belt 1, and the end 21 of the cover belt 2 is buried.
It is constructed by embedding a magnetic material 36 such as a magnet sheet.

As described above, when a magnetic material is attached to the end 11.21 of the belt 1.2, when the belts 1.2 are superimposed on each other, the end 11.21 actively attracts the material, resulting in a close contact. However, it is possible to improve the sealing performance at the end portion where the belts 1 and 2 overlap.

The magnetic plate 35 embedded in the support belt 1 and the magnetic material 36 embedded in the cover belt 2 can be attached to the surfaces of these belts 1.2 by adhesive or other means. In this case, the exposed surfaces of the magnetic plate 35 and the magnetic material 36 are covered with a film made of the same material as the belt 1.2;
That is, the magnetic plate 35. Preferably, the magnetic material 36 is embedded in the belts 1 and 2.

Further, it is preferable that the magnetic plate 35 and the magnetic material 36 are embedded continuously along the longitudinal direction of the belts 1 and 2. However, a long magnetic plate 35. which is equal to the length of the belt 1.2.
It is difficult to obtain the magnetic material 36, and the magnetic plate 35
．． Even if the magnetic material 36 is discontinued, there is little substantial effect.

In addition, when the belts 1.2 to which the magnetic material is attached are used in the conveyor device, the overlapping parts of the ends of these belts 1.2 are actively attracted by the magnetic material, so that the belt lz , 2 can be reduced in longitudinal tension.

<Effects of the Invention> As explained in detail above, the con hair belt of the present invention has the following effects:
Two belts are provided facing each other in order to grip and transport the object (one of the belts is provided with a continuous protrusion along the widthwise edge, so the two belts are When the conveyed object is sandwiched between the two belts, the protrusions are deflected, and this deflection closes the gap between the two belts and the opposing belt. Can be sealed.

Further, in the case where a cavity is provided inside the projection, by reducing the rigidity of the projection, the bending margin of the projection can be increased, and the sealing performance can be improved.

In addition, when a flexible porous material is housed in the void, it is possible to improve the resilience of the bending that occurs in the protrusion.

Furthermore, when a continuous groove is formed on the surface of the protrusion,
When the two belts are superimposed, the partition wall portions of the grooves individually bend, thereby improving sealing performance.

Furthermore, in the case where fibers are attached to the surface of the protrusions, when two belts are superposed, the pressing force acting on the belts causes the fibers to bite into the opposing belt, thereby improving sealing performance. I can do it.

In addition, if one belt is provided with continuous protrusions along the widthwise edge and the other belt is provided with grooves corresponding to the protrusions, when the two belts are overlapped,
By firmly interlocking the surface of the protrusion and the groove corresponding to the protrusion by the pressing force acting on the rear, sealing performance can be improved.

In addition, one belt is provided with a plurality of protrusions made of a flexible material along the widthwise end, and the other belt is provided with a width that can come into contact with all of the plurality of protrusions along the widthwise end. When the planar protrusions are made of a material with a lower hardness than the flexible material, when the two belts are superposed, the plurality of protrusions are flattened by the pressing force acting on the belts. By biting into the shaped protrusion, sealing performance can be improved.

In addition, if a magnetic material is attached to two belts along the widthwise edges, the sealing performance can be improved by bringing the two belts into close contact with each other due to the adsorption force of the magnetic material when they are polymerized. .

Furthermore, if at least one belt is provided with continuous fins whose tips are bent toward the center of the belt along the widthwise edge, when the two belts are superimposed, the fins will bend toward the center of the belt. It has characteristics such as being able to improve sealing performance because it generates flexure.
