Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a freight vehicle equipped with a conveyor device, and more specifically, the present invention relates to a freight vehicle equipped with a conveyor device, and more specifically, a freight vehicle equipped with a conveyor device is provided. This relates to a freight car equipped with brushes for cleaning.

[Prior art]

Freight vehicles that carry cargo boxes such as containers and tanks to transport irregularly shaped objects such as powder and granules are equipped with a structure on the floor of the cargo box to facilitate the unloading of IS objects. Conveyor equipment will be installed. As a conveyor device for accommodating and moving powder and granular materials, a screw type, a belt type, or other type that can continuously unload materials is used. Although the screw type is suitable for unloading powder and granular materials, there are restrictions on what it can transport, and it cannot handle fixed-shaped objects. It is desirable to be able to load objects, and therefore conveyors used for containers are often required to be flat. For example, a belt-type conveyor has the advantage of being endless, moving continuously, and being able to load and unload cargo regardless of its form.

By the way, since a planar conveyor moves loaded objects, a certain amount of clearance is ensured so that the lower part of the inner wall of the container and the side of the conveyor do not come into contact with each other. Therefore, when handling or unloading granules, it is inevitable that some granules will spill from the sides of the conveyor through the gaps onto the floor of the container. Spilled powder and granules can no longer be carried out using a conveyor; once they have accumulated on the floor to a certain extent, they can be scraped out through the opening at the bottom of the container, or sucked up by inserting a suction device into the side of the conveyor. It needs to be cleaned.

Considerations are being taken to reduce the spillage of such transported items, to save the labor of cleaning, and to facilitate unloading. As one example, as shown in FIG. 8, a brush 20 is provided at the bottom of the inner wall of the container, and the inner wall 11 of the container
There is one that covers the gap 35 between the upper surface of the side part and the upper surface of the side part.

While the powder and granular material 13 on the conveyor 3 is stopped by the brush 20 to prevent it from spilling, the conveyor 3 is allowed to move only by contacting the lower end of the brush 20, and the operation of the conveyor is not hindered. do not have. Such brushes 20 are arranged not only on the left and right sides of the container but also on the front side, and can reduce spillage from the conveyor into the container when opening the rear door of the container and unloading powder and granules to the rear. .

[Problem that the invention seeks to solve]

The above-mentioned brush 20 is installed inside the container (with bolts 3 on the regular wall 11).
It is attached via a brush support member 37 fixed at 6. For this reason, particles and the like accumulate on the n-IT of the bolt 36 and on the upper surface of the brush support member 37. Since the object to be transported is moved forward in the direction perpendicular to the plane of the paper, the bolts 36 arranged in the moving direction act to inhibit the movement of the powder and granular material.

Also, a space 38 between the bolt 36 and the brush support member 37
The movement of the powder and granules also deteriorates. In particular, when the transported object is something like wood chips, the chips caught in the head of the bolt 36 or the space 38 obstruct the movement of nearby chips, causing bridges to form and grow.

As a result, even though the conveyor moves, the transported goods do not move, and unloading cannot be carried out smoothly due to idle rotation of the conveyor.

The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a case in which a substantially flat conveyor device is mounted on the floor of a container, and care is taken to prevent the transported goods on the conveyor from spilling due to the brushes. In addition, the bolts and metal fittings used to attach the brushes reduce the openings where conveyed objects can easily accumulate, and furthermore, depending on the shape of the conveyed objects, they can prevent bridges from growing due to getting caught, thereby reducing the idle running of the conveyor. To provide a freight vehicle equipped with a conveyor device that can realize elliptical unloading while avoiding the above problems.

[Means for solving problems]

The features of the freight car with conveyor device of the present invention are explained below with reference to FIG. This is a freight vehicle in which a cargo box is provided on the vehicle body and a conveyor 3 is installed on the floor of the cargo box, and a mounting portion 14 that extends toward the conveyor 3 is formed at the lower part of the inner wall 11 of the cargo box. A brush support member 21 that hangs down and fixes the sealing brush 20 that contacts the upper surface of the conveyor 3 can be attached to the mounting portion 14 with a countersunk bolt 22, and fills the space above the brush 20, and the brush support member 21 A dish pole that fixes it to the mounting part 14! - A pressing member 26 in which 22 bolt holes 25 are formed is provided.

[For production]

A pressing member 26 that presses the brush supporting member 21 is arranged on the brush supporting member 21 that attaches the brush 20 to the inner wall 11 of the packing box, and the pressing member 26 has a plate with a non-protruding head. Since the bolt 22 is used, a highly uneven shape that would cause the transported object 13 such as powder or granules to accumulate or become stuck is eliminated. Therefore, the stagnation of the transported articles 13 on the conveyor 3 is extremely reduced.

〔Effect of the invention〕

Brush support f (i) Since there are no spaces or protrusions on the material where transported objects can accumulate or get caught, transported objects may become stagnant or bridges may occur and grow.
Elephants will disappear. Therefore, the transported items can be unloaded smoothly without the conveyor running idle. The brush prevents the conveyed material, such as powder, from spilling from the side of the conveyor onto the floor of the container, and the brush can be replaced by attaching and removing the countersunk bolts.

〔Example〕

Hereinafter, the present invention will be explained in detail based on examples thereof.

FIG. 2 shows an example of a cargo automatic hoist to which the present invention is applicable, in which a container 2, which is a cargo box, is provided on a grass 1.
A conveyor 3 is installed on the floor of the machine. The conveyor 3 has a flat surface and is capable of transporting not only regular shaped objects but also irregular shaped objects such as powder and granular materials and wood chips. In this example, a conveyor 3 consisting of a large number of supporting members 4 and a shielding member 5 that fills the gaps between them as shown in FIG. , and each support member 4
By fixing a chain link 8 to the conveyor, an endless conveyor is formed. As shown in FIG. 4, this conveyor 3 vertically surrounds girders 9 placed on the left and right at the bottom of the container 2, and the upper side, where the amount of fff of the conveyed material acts, is connected to a rail 10 installed on the girders 9. Supported.

The lower part of the inner wall 11 of the container 2 is composed of a side plate 12, and a mounting portion 14 that extends toward the conveyor 3 is formed on the side of the transported object 13.

To explain the drive structure of the conveyor 3 in simple terms based on FIG. The upper side of the conveyor moves forward when loading boxes and backwards when unloading by rotating a motor 17 (see Figure 2). The chain 7 is movably supported on a support base 19 covered with a resin cover 18. By the way, the support member 4 is made of aluminum or the like, and as shown in Fig. 3, the inner sides are close to each other at the front and rear ends where the sprocket 6 is located, so there is a gap to prevent mutual interference. is open. If the gap remains as it is, it will be impossible to operate irregularly shaped objects such as powder or granular materials, so the above-mentioned shielding member 5, which is fitted with vinyl chloride, etc., is adopted, and the deformation is used to prevent the return. bending is possible.

Such a conveyor 3 is provided with a sealing brush 20 that comes into contact with the upper surface of the conveyor, as shown in FIG. To explain in detail with reference to FIG. 1, a brush support member 21 that suspends and fixes the brush 20 can be attached to and detached from the above-mentioned mounting portion 14 with a countersunk bolt 22. That is, the brush support member 21 includes a brush holding part 23 that holds the brush 20 between them at the lower part, and a mounting part 1 that holds the brush 20.
4, and a flat plate portion 24 for attaching to the countersunk bolt 2.
2, and can be removed by loosening the countersunk bolt 22. The brush holding part 23 is a plate-like part 24
A suppressing member 26 is provided which protrudes further than the brush 20 so as to fill the space above the brush 20 and is formed with a bolt seat 25 for the countersunk bolts 2, 2 for fixing the brush support member 21 to the mounting portion 14. Note that the plate-shaped portion 24 and the pressing member 26 are designed to be as thin as possible.
In order to securely fix the thin pressing member 26 and prevent the head from protruding, it is recommended to use the above-mentioned countersunk bolt 22!'3f! It is LgJ. It is most convenient to use a flat bolt as shown, but a nine-sunk bolt with an extremely small protrusion can also be used. These countersunk bolts 22 are screwed into the side plate 12, and in order to increase the amount of screw engagement, in this example, a protrusion 27 is formed to prevent the side plate 12 from being pulled out by a simple pulling operation. A screw hole body 28 that can be fixed is employed.

The operation of the conveyor device configured as described above will be explained next. On the brush support member 21 that attaches the brush 20 to the inner wall 11 of the container 2, the brush support member 2
There is a pressing member 26 that presses 1. Since the countersunk bolt 22 with no protruding head is used for the pressing member 26, the brush holding f (I! 23 and above is in a plane shape. As a result, the grains and grains are not transported). There is no longer a highly uneven shape that can cause lumps or snags.

Therefore, phenomena such as stagnation of the transported goods or the formation and growth of bridges are suppressed, and the transported goods can be unloaded smoothly without the conveyor running idly. Of course, the brush 20 removes the conveyed materials such as powder and granules from the conveyor 3.
This prevents spillage from the sides of the brush onto the floor 2a of the container 2 (see Figure 4).In addition, by removing the countersunk bolt 22, the worn brush 20 can be easily replaced with a In this case, since the pressing member 26 can be reused, the cost can be reduced.

By the way, as shown in FIG.
A cover 29 facing the upper surface of the conveyor 3 is attached to the lower end of the attachment portion 14 with rivets 30. This is to prevent the brush 20, which should be bent toward the transported IPJ object 13 as shown in the figure, from being reversed and bent toward the side edge of the conveyor 3 when the conveyor 3 moves.

That is, it is maintained in order to narrow the distance between the lower end of the side plate 12 and the upper surface of the conveyor 3. On the other hand, there is usually one motor 17 for moving the conveyor 3, and when the motor 17 is in the front as shown in FIG. 4 may behave as if it were a little louder.

At this time, the above-mentioned cover 29 functions to prevent damage caused by contact between the side plate 12 and the support member 4. Note that a slightly soft material such as vinyl chloride is selected for the cover 29 so that even if it comes into contact with the conveyor 3, large resistance will not be applied. The above-mentioned rivet 30 fixing the cover 29
The head of the conveyed object 13 is covered by the brush 20.
This cover 29 and the above-mentioned mounting structure of the brush 20 do not obstruct the movement of the conveyor, but the front end of the conveyor, that is, the return section, is also maintained at the front end of the conveyor, and the rear part is opened for unloading the conveyor. Provided around the bottom of the container, except for

FIG. 6 shows a different embodiment, in which a rubber plate 31 is interposed in the brush holding portion 23 so as to cover the surface of the brush 20 on the conveyance object 13 side. If only the brush 20 is used, unevenness may occur to a greater or lesser extent on the side that comes into contact with the transported object, and the transported object may get caught.

It is preferable to cover most of the brush 20 with a rubber plate 31 in order to improve the sliding with the transported object so that smooth movement is not hindered and to reduce wear and tear on the brush 20.

The brush mounting structure in the freight vehicle with a conveyor device described above is not limited to the conveyor having the above-mentioned configuration, and may be applied, for example, to the conveyor 33 of the type shown in FIG. 7 in which the belt 32 is made endless and moves. can also be applied. In other words, the present invention is most effective when the vehicle is a freight vehicle that transports irregularly shaped objects such as powder and granules and wood chips, and the cargo can be loaded and moved in its cargo box. can be demonstrated.
