Description

  The present invention relates to a transport device having a transport surface that is looped around a drive pulley and a driven pulley.

  As this type of conveying device, there are a belt conveyor (belt feeder), an apron conveyor (apron feeder), etc. (see Patent Document 1, Patent Document 2, Patent Document 3, etc.), for example, the belt conveyor is a thermal power plant, In steelworks, chemical plants, sewage treatment plants, garbage treatment plants, etc., they are used to transport various materials, fuels, processed materials, wastes and other objects to be transported. In general, this belt conveyor wraps a rubber belt of a predetermined width between a drive pulley and a driven pulley, and rotates the drive pulley to rotate the belt between the two pulleys, thereby transferring the object to be conveyed. It is transported (see Patent Document 1, FIG. 1, Patent Document 2, FIG. 1, Patent Document 4, FIG. 5, etc.).

Conventional conveyors, including conveyors using this type of rubber belt, convey one type of object to be conveyed by one conveyance surface.
On the other hand, a belt conveyor in which a reciprocating path of a conveyance path is provided in parallel has been proposed (see Patent Document 4). In addition, a conveyor device has also been proposed in which a cross rail is provided at a required interval over the entire length in the length direction of the belt and the conveyance surface is divided in the length direction (see Patent Document 5).

Utility Model Registration No. 3006034 Japanese Utility Model Publication No. 7-2328 JP 2013-107720 A JP 2001-19136 A JP 2008-162752 A

  In any of the above conveying apparatuses, there is only one type of object to be conveyed by one conveying surface.

  This invention makes it a subject to enable it to convey a several different to-be-conveyed object in the conveying apparatus which consists of said one conveyance surface under the said actual condition.

In order to achieve the above object, according to the present invention, a partition wall extending over the entire length in the circumferential direction is provided on the transport surface.
Since one transfer surface is divided into a plurality of parts by this partition wall, each transferred object is transferred by movement of one transfer surface by feeding individual transferred objects into the divided transfer paths. Can do.

As a configuration of the present invention, in a transport device having a transport surface that circulates between a driving pulley and a driven pulley, a partition wall is provided on the transport surface over the entire length in the circumferential direction, and the partition wall The conveyance surface can be divided into a plurality of portions in the width direction, and the partition wall can be expanded and contracted in the conveyance direction of the conveyance surface.
In this configuration, when the transport surface circulates around the driving pulley and the driven pulley and moves in an arc shape, the partition wall expands and contracts and smoothly circulates both pulleys in response to changes in the circular trajectory.

  For example, if the conveying device is a belt conveyor, the conveying surface is constituted by a belt, and if the conveying device is the apron conveyer, the apron is constituted by the apron, and the belt or apron that forms the conveying surface is accompanied by traveling (moving). The transported object is also moved and transported.

  The partition wall can be provided with one or more strips in the width direction of the conveyance surface. The number of divisions of the conveyance surface is determined based on the number of the stripes. For example, if the number is one, two division conveyance surfaces are obtained. In the case of one partition wall, the partition wall is shifted from the center in the width direction of the conveyance surface, and in the case of a plurality of partition walls, if the intervals between the partition walls are different, the width of each divided conveyance surface is different, This is effective when the amount of objects to be conveyed is different.

  In the transport device having this configuration, there are partition walls on the divided transport paths (transport surfaces), but since there are no obstacles on the both sides of the entire length in the circumferential direction, a scraper device can be provided respectively.

The partition wall can be expanded and contracted by forming the partition wall with an elastic body such as rubber, making it accordion-like, or making a longitudinal cut at a required interval in the length direction. In addition, the partition wall is divided into a plurality of parts in the circumferential direction of the transport surface, and each of the divided pieces overlaps with the side edges of the adjacent parts so that the overlap occurs in the traveling direction when the drive pulley and the driven pulley move in an arc shape. It can also be set as the structure which does not cancel | release by expanding and contracting.
The partition wall or each of the divided pieces may be integrally formed with a member such as a belt that forms the conveyance surface, but if the member is separate from the member, the separate partition wall or the divided piece becomes a member that forms the existing conveyance surface. Since it can attach by adhesion | attachment, a screw stop, etc., conveying apparatuses, such as an existing belt conveyor and an apron conveyor, can be based on this invention.

  Since the present invention is configured as described above so that a plurality of different objects to be conveyed can be conveyed in a conveying apparatus having one conveying surface, the amount of conveyance is small, and a plurality of different objects to be conveyed can be simultaneously conveyed. In the case of transporting or transporting a plurality of different transported objects that should not be mixed even if not simultaneously, an inexpensive transport device can be provided.

  One embodiment of a belt conveyor which is a conveying device according to the present invention is shown in FIGS. 1 to 3, and this belt conveyor B is made of rubber having a predetermined width between a driving pulley 2 and a driven pulley 3 as in the prior art. The belt 1 is wound and the driving pulley 2 is rotated by the motor M, whereby the belt 1 is rotated between the pulleys 2 and 3 in the direction of arrow a (see FIG. 1B). The forward guide rollers 4 are provided at a required interval at the center and both sides in the width direction of the lower surface of the forward path of the belt 1, so that both ends of the belt 1 are raised in the forward path so that the conveyed object does not spill from the belt 1. In the figure, 5 is a return path guide roller, and F is an apparatus frame.

  The circulating belt 1 has an upper surface as a conveying surface in the forward path and a lower surface as a conveying surface in the returning path. Hereinafter, the conveying surface (conveying path) of the circulating belt 1 is appropriately denoted by reference numeral 1. A partition wall 10 is provided at the center of the conveying surface (belt) 1 that circulates over the entire length in the circumferential direction (length direction).

  As shown in FIG. 3, the partition wall 10 is made of the same material as the belt 1 divided into a plurality of parts in the circumferential direction of the conveying surface (belt) 1. Each of the divided pieces 11 is composed of a reverse isosceles trapezoidal plate piece, and an attachment piece 12 is provided on the lower edge of the plate piece. The attachment piece 12 is attached to the transport surface 1 by bonding or screwing. By attaching, each division | segmentation piece 11 is fixed to the belt 1, and the partition wall 10 covering the circumference direction full length of the belt 1 is formed in the center of the width direction on the conveyance surface of the belt 1 (refer FIG. 2).

  As shown in FIG. 3, the divided pieces 11 fixed to the belt 1 overlap each other even when the adjacent side portions overlap each other and move in an arc shape in the portions of the driving pulley 2 and the driven pulley 3. Cannot be released due to expansion / contraction (the degree of overlap changes). At this time, if the attachment piece 12 is also divided into a required number along the lower edge of the divided piece 11 as shown in FIG. 3, the deformation into the arc shape is facilitated.

In this belt conveyor B, since the conveyance path 1 is divided, two head chutes S on the driven pulley 3 side and hopper H on the drive pulley 2 side are provided so as to correspond to both the conveyance paths 1a and 1b.
In addition, the divided conveying paths 1a and 1b have a partition wall 10 at the center of the belt 1, but there are no obstacles on the both sides of the entire length in the band direction. ing. As the scraper device C, a conventionally known one shown in FIGS. 1 and 4 of Patent Document 2 is adopted.

The belt conveyor B of this embodiment has the above-described configuration. When the belt 1 is traveling, different types of objects to be conveyed D ₁ and D ₂ from the head chutes S and S are divided and conveyed on the left and right sides. When the belt 1 is fed to the roads 1a and 1b, the belt 1 is simultaneously transported along the forward path, and both the articles to be transported D ₁ and D ₂ are fed to the respective hoppers H. In the return path, in the respective divided transport paths 1a and 1b, the objects to be transported D ₁ and D ₂ attached to the transport surfaces 1a and 1b by the scraper device C are peeled off.

  4A, 4B, and 5 show other examples of the partition wall. The partition wall 10a has the above-described divided pieces 11 continuous, and the belt-like wall 11a is directed from the lower edge to the upper edge. This is a bellows shape in which the amplitude of the band-like wave gradually increases. Therefore, even if the belt 1 travels and moves in an arc shape in the portions of the drive pulley 2 and the driven pulley 3 as shown in FIG. 4B, the partition wall 10a changes the degree of wave amplitude. The bellows portion is opened and closed and allowed to move in its arc shape, and there is no break.

6 to 8 show still other examples of the partition wall. As shown in FIG. 6, the partition wall 10 b includes two types of divided pieces 10 b ₁ and 10 b ₂ , and the two divided pieces 10 b ₁ , 10b ₂ except that both ends of the upper edge of the rising portion 11b of one side (FIG. 8A) are inclined surfaces, and the same upper edge of the other side (FIG. 8B) is linear. It has the same shape. The divided pieces 10b ₁ and 10b ₂ are made of a flexible material such as the same quality rubber or flexible resin as the belt 1.
The rising portion 11b has an isosceles trapezoidal frame shape with a vertical cross section, and has a piece-like attachment portion 12b extending in the lateral direction at the lower edge thereof. By attaching the attachment portion 12b to the belt 1 with screws 6, the divided pieces 10b ₁ and 10b ₂ are fixed to the belt 1, and a partition covering the belt 1 in the width direction at the center in the width direction on the conveying surface of the belt 1. A wall 10b is formed (see FIG. 6). Instead of screws, bonding may be performed.

The divided piece _10b 1, 10b _2, as shown in FIG. 7, one divided piece 10b ₁ and the other divided piece 10b ₂ to the frame-shaped both the rising portion 11b, when connected by fitting of 11b, from the rising portion 11b The partition wall 10b part which overlaps overlaps so that there may be no gap. Similarly to the above embodiment, even if the connected divided pieces 10b ₁ and 10b ₂ move in an arc shape in the portions of the driving pulley 2 and the driven pulley 3 with adjacent side edges overlapping, The overlap cannot be released due to expansion / contraction (the degree of overlap changes). At this time, the arcuate movement is smoothly performed by the inclined surfaces at both ends of the upper edge of the _one divided piece 10b1.

9 and 10 show still another example of the partition wall. This partition wall 10c extends the mounting portions 12b of the divided pieces 10b ₁ and 10b ₂ to the side in the embodiment shown in FIG. A U-shaped hook portion 13 that fits on the side edge of the belt 1 is provided at the end of the lever. As shown in FIG. 9, the hook portion 13 is fitted to the side edge of the belt 1 and fixed to the belt 1 by adhesion, screwing, or the like, so that the band direction of the belt 1 is centered in the width direction on the conveying surface of the belt 1. A partition wall 10c extending over the entire length is formed. If the divided pieces 10b ₁ and 10b ₂ are fixed to the belt 1 only by fitting the hook portion 13 to the side edge of the belt 1, the bonding or the like is not necessary.

In each of the above embodiments, the belt conveyor B is shown as the conveying device. However, the conveying device having the conveying surface 1 that is wound around the driving pulley 2 and the driven pulley 3, for example, an conveying device such as an apron conveyor. If so, the present invention can be adopted. In the case of the apron conveyor, a partition wall can be provided for each apron, and the side edges of the adjacent partition walls overlap each other, and the overlap is conveyed even when the drive pulley and the driven pulley are moved in an arc shape. Stretch in the direction to prevent it from being released.
In addition, the partition walls 10, 10a,... Are separate parts from the member that forms the conveying surface such as a belt, but both may be formed as an integrally molded product. Multiple lines can be provided.
Thus, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is defined by the terms of the claims, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
