[0009] Hereinafter, a conveying device according to an embodiment of the present disclosure will be described with reference to the drawings. The embodiment shows one aspect of the present disclosure, and does not limit the present disclosure. The embodiment can be arbitrarily modified within the scope of the technical concept of the present disclosure.

[0010] Fig. 1 is a diagram showing a schematic configuration of a conveying device 1 according to an embodiment. Fig. 2 is a schematic diagram showing the configuration of the conveying device 1 according to an embodiment as viewed from a conveying direction D1. The conveying device 1 conveys an object X input into a hopper 100. In the present disclosure, the direction in which the conveying device 1 conveys the object X (the conveying direction of the object X) is defined as a conveying direction D1. A direction intersecting with the conveying direction D1 is defined as an intersecting direction D2.

[0011] In one embodiment, as shown in Fig. 1, the hopper 100 is formed with an inlet 106 that opens upward and through which the transported object X is introduced, and an outlet 104 that is located below the inlet 106 and through which the transported object X is discharged. The outlet 104 is formed by positioning a lower end 110 of a front wall 108 on the downstream side of the hopper 100 in the transport direction D1 above the transport device 1. This outlet 104 opens in the horizontal direction. A lower end 112 of the front wall 108 of the hopper 100 approaches the transport device 1 as it moves toward the upstream side in the transport direction D1. The transport device 1 is configured to discharge (cut out) the transported object X from the outlet 104 at preset intervals and amounts.

[0012] The transported goods X is not particularly limited, and may be, for example, fuel for a boiler. Such transported goods X may include crushed waste plastic (so-called fluff) or tire chips, or may be a mixture of fluff and tire chips.

[0013] 1, the hopper 100 opens downward. The conveying device 1 is disposed below this opening, and the transported object X put into the hopper 100 is placed thereon. In other words, the conveying device 1 has a placement surface 102 on which the transported object X is placed. In some embodiments, the bottom wall of the hopper 100 has the placement surface 102.

[0014] The conveying device 1 includes a conveyor chain 2 having a plurality of chain links 4 arranged side by side along a conveying direction D1. The plurality of chain links 4 are connected to each other. The conveyor chain 2 is wound around a driving sprocket 3 as a driving shaft and a driven sprocket 5 as a driven shaft, and is configured to be able to move in a circular motion by the rotation of the driving sprocket 3. In one embodiment, the driving sprocket 3 is located downstream (head side) of the driven sprocket 5 in the conveying direction D1. The conveying device 1 further includes an electric motor 9 that rotates and drives the driving sprocket 3.

[0015] In one embodiment, as illustrated in Fig. 1, the conveying device 1 further includes an upstream anti-compaction bar 70 and a downstream anti-compaction bar 72 disposed in the hopper 100 above the conveyor chain 2. Each of the upstream anti-compaction bar 70 and the downstream anti-compaction bar 72 has a rod shape and extends along the cross direction D2. The downstream anti-compaction bar 72 is located downstream of the upstream anti-compaction bar 70 in the conveying direction D1. The downstream anti-compaction bar 72 is located below the upstream anti-compaction bar 70.

[0016] In the embodiment illustrated in FIG. 1, the conveying device 1 includes three upstream anti-compaction bars 70 and two downstream anti-compaction bars 72. The three upstream anti-compaction bars 70 include, in order from the upstream side in the conveying direction D1, a first upstream anti-compaction bar 70A (70), a second upstream anti-compaction bar 70B (70), and a third upstream anti-compaction bar 70C (70). The second upstream anti-compaction bar 70B is located above the first upstream anti-compaction bar 70A and the third upstream anti-compaction bar 70C. In the up-down direction D3, the first upstream anti-compaction bar 70A and the third upstream anti-compaction bar 70C overlap each other. That is, the first upstream anti-consolidation rod 70A, the second upstream anti-consolidation rod 70B, and the third upstream anti-consolidation rod 70C are arranged to form the vertices of an imaginary triangle when viewed from the cross direction D2. The two downstream anti-consolidation rods 72 include, from top to bottom in the up-down direction D3, the first downstream anti-consolidation rod 72A (72) and the second downstream anti-consolidation rod 72B (72), and in the conveying direction D1, the first downstream anti-consolidation rod 72A and the second downstream anti-consolidation rod 72B overlap each other.

[0017] In one embodiment, as illustrated in FIG. 2, the conveying device 1 includes four conveyor chains 2. The four conveyor chains 2 are arranged at intervals in the cross direction D2. The four conveyor chains 2 are configured to be synchronized with each other. Specifically, each of the four conveyor chains 2 conveys an object X such that the object X moves at a similar distance to each other. In some embodiments, the conveying device 1 includes one conveyor chain 2, or two or more conveyor chains 2.

[0018] The configuration of the chain link 4 will be described. FIG. 3 is a diagram showing a schematic configuration of a portion of one conveyor chain 2 according to one embodiment. As described above, the conveyor chain 2 has a plurality of chain links 4 connected to each other. As shown in FIG. 3, the chain link 4 includes a first link plate 6, a second link plate 8 located on the opposite side of the first link plate 6 across a gap 7 in the cross direction D2, and a conveying member 10 connecting the first link plate 6 and the second link plate 8. The conveying member 10 is configured to press the conveyed object X that has entered the gap 7. Such a conveying member 10 is, for example, a plate-shaped member having a pressing surface 11 facing the gap 7.

[0019] An example of a configuration for connecting adjacent chain links 4 will be described. In the embodiment illustrated in FIG. 3, the one-side link plate 6 includes a one-side downstream end 20, a one-side upstream end 22, and a one-side connection portion 24 that connects the one-side downstream end 20 and the one-side upstream end 22. The one-side downstream end 20 is located downstream of the one-side upstream end 22 in the conveying direction D1 and on the other side of the cross direction D2 (on the right side in the plane of FIG. 3). Similarly, the other-side link plate 8 includes a other-side downstream end 30, a other-side upstream end 32, and a other-side connection portion 34 that connects the other-side downstream end 30 and the other-side upstream end 32. The other-side downstream end 30 is located downstream of the other-side upstream end 32 in the conveying direction D1 and on one side of the cross direction D2 (on the left side in the plane of FIG. 3).

[0020] The one-side link plate 6 is fixed to the adjacent one-side link plate 6 on the downstream side in the conveying direction D1 by the one-side pin 26. Specifically, the one-side upstream end 22 of the adjacent one-side link plate 6, the one-side downstream end 20 of the one-side link plate 6, and the conveying member 10 are arranged in order from one side of the cross direction D2. The one-side upstream end 22 of the adjacent one-side link plate 6, the one-side downstream end 20 of the one-side link plate 6, and the conveying member 10 are fixed to each other by being inserted into the one-side pin 26 from one side of the cross direction D2. Similarly, the other-side link plate 8 is fixed to the other-side link plate 8 adjacent to the downstream side in the conveying direction D1 by the other-side pin 36. Specifically, the other-side upstream end 32 of the adjacent other-side link plate 8, the other-side downstream end 30 of the other-side link plate 8, and the conveying member 10 are arranged in order from the other side of the cross direction D2. The other-side upstream end 32 of the adjacent other-side link plate 8, the other-side downstream end 30 of the other-side link plate 8, and the conveying member 10 are fixed to each other by being inserted into the other-side pin 36 from the other side of the intersecting direction D2. Both the one-side pin 26 and the other-side pin 36 are inserted into the conveying member 10.

[0021] As shown in FIG. 3, the multiple chain links 4 include a chain link with an attachment 14(4) and a chain link without an attachment 16(4). In one embodiment, the chain link with an attachment 14 is provided with both a one-side attachment 15 protruding from an outer surface 6b opposite to the surface 6a of the one-side link plate 6 on the gap 7 side, and a other-side attachment 17 protruding from an outer surface 8b opposite to the surface 8a of the other-side link plate 8 on the gap 7 side. In some embodiments, the chain link with an attachment 14 is provided with the one-side attachment 15 or the other-side attachment 17. The chain link without an attachment 16 is provided with neither the one-side attachment 15 nor the other-side attachment 17.

[0022] In one embodiment, the conveyor chain 2 includes a plurality of chain links 14 with attachments that are arranged at predetermined intervals from one another in the conveying direction D1. For example, the conveyor chain 2 includes 50 chain links 4 that are connected to one another along the conveying direction D1. Among the 50 chain links 4, the first chain link 4, the eleventh chain link 4, the twenty-first chain link 4, the thirty-first chain link 4, and the forty-first chain link 4 are chain links 14 with attachments, and the remaining chain links 4 are chain links 16 without attachments.

[0023] In one embodiment, as illustrated in Figure 3, the length in the cross direction D2 from the left end to the right end of the gap 7 is L1, the length in the cross direction D2 from the left end of the gap 7 to the left end of the one-side attachment 15 is L2, and the length in the cross direction D2 from the right end of the gap 7 to the right end of the other-side attachment 17 is L3, so that L1 / 3>L2>L1 / 5 and L1 / 3>L3>L1 / 5 are satisfied, respectively.

[0024] 3, in order to interface with the driving sprocket 3 and the driven sprocket 5, respectively, one-side attachment 15 is located at the center of one-side link plate 6, and the other-side attachment 17 is located at the center of the other-side link plate 8. Specifically, one-side attachment 15 is mounted on one-side connection portion 24, and the other-side attachment 17 is mounted on the other-side connection portion 34.

[0025] A specific configuration of the one-side attachment 15 will be described. In the present disclosure, the other-side attachment 17 is configured similarly to the one-side attachment 15 (including the first inclined plate 40, the second inclined plate 42, and the lower plate 44) except for the installation position, so a description of the configuration of the other-side attachment 17 will be omitted. The other-side attachment 17 does not need to be configured identically to the one-side attachment 15. For example, the other-side attachment 17 may have a larger dimension than the one-side attachment 15. The other-side attachment 17 may not include the lower plate 44.

[0026] Fig. 4 is a diagram showing a schematic configuration of the one-side attachment 15 according to one embodiment, as viewed from the intersecting direction D2. As shown in Fig. 4, the one-side attachment 15 includes a first inclined plate 40, a second inclined plate 42, and a lower plate 44. Each of the first inclined plate 40, the second inclined plate 42, and the lower plate 44 has a plate shape.

[0027] The first inclined plate 40 is inclined such that a downstream end 46 on the downstream side of the conveying direction D1 is located lower than an upstream end 48 on the upstream side of the conveying direction D1 when viewed from the cross direction D2. In one embodiment, the downstream end 46 of the first inclined plate 40 is located lower than a center O of the outer side surface 6b in the up-down direction D3. The downstream end 46 of the first inclined plate 40 is very close to the lower surface 6c of the one-side link plate 6 so as to be able to press the base of the conveyed object X that has entered the side space 101 (described later). The upstream end 48 of the first inclined plate 40 is located lower than an upper surface 6d of the one-side link plate 6.

[0028] The second inclined plate 42 is inclined such that a downstream end 50 on the downstream side of the conveying direction D1 is located higher than an upstream end 52 on the upstream side of the conveying direction D1 when viewed from the intersecting direction D2. The downstream end 50 of the second inclined plate 42 is connected to the upstream end 48 of the first inclined plate 40. The first inclined plate 40 and the second inclined plate 42 are integrally configured as a single component as a whole.

[0029] The lower plate 44 covers a space 54 defined by the lower surface 41 of the first inclined plate 40 and the lower surface 43 of the second inclined plate 42 from below.

[0030] (Action and effect) The operation and effect of the conveying device 1 according to an embodiment will be described. FIG. 5 is a diagram for explaining retention of the transported object X in the conventional conveying device 1'. The conventional conveying device 1' cannot convey the transported object X that enters the spaces (hereinafter referred to as side spaces 101) on both sides of the cross direction D2 of the conveyor chain 2' among the transported object X put into the hopper 100, and may cause the transported object X to be retained in the hopper 100. Then, as shown in FIG. 5, an arch-shaped mass of transported objects (hereinafter referred to as bridge XB) is formed with the transported object X retained in the side space 101 as a fulcrum. The bridge XB is removed by an operator, for example, but the removal requires man-hours and the transporting device 1 is stopped for a period of time.

[0031] In one embodiment, to address the problem of the formation of the bridge XB, each of the one-side attachment 15 and the other-side attachment 17 presses the transported object X that has entered the side space 101. This prevents the formation of a fulcrum for the bridge XB, and suppresses the retention of the transported object X in the hopper 100. In other words, the man-hours required to remove the bridge XB and the time the transport device 1 is stopped can be suppressed.

[0032] If the one-side attachment 15 and the other-side attachment 17 are each designed to be short in the cross direction D2, the transported object X that has entered the side space 101 may not be pressed, or only a small amount of the transported object X may be pressed, and a bridge XB may be formed. On the other hand, if the one-side attachment 15 and the other-side attachment 17 are each designed to be long in the cross direction D2, the load acting on the one-side attachment 15 and the other-side attachment 17 may become large, and the one-side attachment 15 and the other-side attachment 17 may be damaged. According to one embodiment, the conveying device 1 satisfies L1 / 3>L2>L1 / 5 and L1 / 3>L3>L1 / 5 (L1: length of the gap 7 in the cross direction D2, L2: length of the one-side attachment 15 in the cross direction D2, L3: length of the other-side attachment 17 in the cross direction D2). Therefore, each of the one-side attachment 15 and the other-side attachment 17 can have the function of preferably pressing the article X that has entered the side space 101.

[0033] According to one embodiment, the multiple chain links 4 include chain links 14 with attachments and chain links 16 without attachments, so that the installation costs of the conveying device 1 can be reduced by preparing a number of chain links 14 with attachments corresponding to the transported object X, for example, based on the ease of forming the bridge XB.

[0034] FIG. 6 is a diagram for explaining the action and effect of the upstream anti-compaction bar 70 and the downstream anti-compaction bar 72 according to one embodiment. According to one embodiment, the conveying device 1 includes the upstream anti-compaction bar 70 and the downstream anti-compaction bar 72. Therefore, when the transported object X is put into the hopper 100 from above, it can be dropped into the upstream anti-compaction bar 70 arranged in a triangular shape, thereby dispersing the transported object X (the accumulation of the transported object X biased to one part in the hopper 100 can be suppressed). Furthermore, when the conveying device 1 conveys the transported object X to the downstream side in the conveying direction D1, each of the upstream anti-compaction bar 70 and the downstream anti-compaction bar 72 can disperse the transported object X in the up-down direction D3. At this time, as shown in FIG. 6, the downstream anti-compaction bar 72 further disperses the transported object X dispersed downward by the upstream anti-compaction bar 70 in the upward and downward directions. Therefore, the effect of dispersing the transported object X can be enhanced, and the compression of the transported object X can be suppressed. In addition, each of the upstream anti-compaction bar 70 and the downstream anti-compaction bar 72 may be provided in a conventional conveying device 1'.

[0035] According to one embodiment, each of the one-side attachment 15 and the other-side attachment 17 includes the first inclined plate 40, so that when the first inclined plate 40 presses the transported object X that has entered the side space 101, the force acting on the first inclined plate 40 can be directed downward. Therefore, the chain link 14 with the attachment can be prevented from floating up via the first inclined plate 40.

[0036] According to one embodiment, the downstream end 46 of the first inclined plate 40 is located below the center O of the outer surface 6b, so that the article X that has entered the side space 101 can be pressed from its base.

[0037] According to one embodiment, the upstream end 48 of the first inclined plate 40 is located below the upper surface 6d of the one-side link plate 6, so that the amount of the article X that can be pushed is limited, and the magnitude of the force that the article X exerts on the first inclined plate 40 can be suppressed. Therefore, the load on the conveyor chain 2 can be reduced.

[0038] According to one embodiment, each of the one-side attachment 15 and the other-side attachment 17 includes a second inclined plate 42, which reinforces the first inclined plate 40 and suppresses damage (bending) of the first inclined plate 40 due to the force acting on the first inclined plate 40 by the transported item X.

[0039] According to one embodiment, each of the one-side attachment 15 and the other-side attachment 17 includes a lower plate 44, which prevents the transported item X from entering the space 54 and suppresses the first inclined plate 40 and the second inclined plate 42 from floating up.

[0040] FIG. 7 is a schematic diagram showing a configuration of a portion of two conveyor chains 2 according to some embodiments. In some embodiments, as shown in FIG. 7, the conveying device 1 includes a first conveyor chain 2A and a second conveyor chain 2B(2) that are spaced apart from each other in a cross direction D2 with respect to the first conveyor chain 2A(2). The second conveyor chain 2B is configured to be synchronized with the first conveyor chain 2A. The chain links 14 with attachments of the first conveyor chain 2A and the chain links 14 with attachments of the second conveyor chain 2B are arranged so as not to overlap each other in the conveying direction D1.

[0041] 7, the object X entering the side space 101 can be pressed from both sides in the cross direction D2, and the first conveyor chain 2A and the second conveyor chain 2B can be prevented from interfering with each other. Also, the number of attachment-equipped chain links 14 installed in the conveying device 1 can be reduced.

[0042] The contents described in each of the above embodiments can be understood, for example, as follows.

[0043] [1] The conveying device (1) according to the present disclosure is A conveying device that conveys an object (X) to be fed into a hopper (100), The conveyor system includes at least one conveyor chain (2) having a plurality of chain links (4) arranged side by side along a conveying direction (D1) of the conveyed object and connected to each other, Each of the plurality of chain links includes a first link plate (6), a second link plate (8) located on the opposite side of the first link plate across a gap (7) in a cross direction (D2) crossing the conveying direction, and a conveying member (10) configured to connect the first link plate and the second link plate and to press the conveyed object that has entered the gap, At least one of the plurality of chain links includes a chain link (14) with an attachment having at least one of a one-side attachment (15) protruding from an outer surface (6b) opposite the gap side surface of the one-side link plate, and a other-side attachment (17) protruding from an outer surface (8b) opposite the gap side surface of the other-side link plate.

[0044] Conventional conveying devices cannot convey objects that enter the spaces (side spaces) on both sides of the conveyor chain in the crossing direction among the objects fed into the hopper, and may cause the objects to be stuck in the hopper. As shown in FIG. 5, an arch-shaped mass of objects (bridge) is formed with the objects stuck in the side spaces as a fulcrum. According to the configuration described in [1] above, the one-side attachment and the other-side attachment each press the objects located in the side spaces, preventing the formation of a fulcrum for the bridge. This makes it possible to suppress the objects from being stuck in the hopper.

[0045] [2] In some embodiments, in the configuration described in [1] above, The one-side attachment includes a plate-shaped first inclined plate (40), The first inclined plate is inclined such that, when viewed from the intersecting direction, a downstream end (46) on the downstream side in the conveying direction is located lower than an upstream end (48) on the upstream side in the conveying direction.

[0046] According to the configuration described in [2] above, when the first inclined plate presses against the transported object that has entered the side space, the force acting on the first inclined plate can be directed downward, which makes it possible to prevent the chain link with the attachment from floating up via the first inclined plate.

[0047] [3] In some embodiments, in the configuration described in [2] above, The downstream end of the first inclined plate is located below the center (O) of the outer surface of the one side link plate.

[0048] According to the configuration described in [3] above, the article that has entered the side space can be pressed from a low position.

[0049] [4] In some embodiments, in the configuration described in [2] or [3] above, The upstream end of the first inclined plate is located below the upper surface (6d) of the one side link plate.

[0050] According to the configuration described in [4] above, the magnitude of the force acting on the first inclined plate by the transported object can be suppressed, and therefore the load on the conveyor chain via the first inclined plate can be reduced.

[0051] [5] In some embodiments, in the configuration according to any one of [2] to [4] above, The one-side attachment includes a plate-shaped second inclined plate (42), the second inclined plate is inclined such that, when viewed from the intersecting direction, a downstream end (50) on the downstream side in the conveying direction is located higher than an upstream end (52) on the upstream side in the conveying direction, The downstream end of the second inclined plate is connected to the upstream end of the first inclined plate.

[0052] According to the configuration described in [5] above, the first inclined plate is reinforced by the second inclined plate, and damage (bending) of the first inclined plate due to the force acting on the first inclined plate from the transported object can be suppressed.

[0053] [6] In some embodiments, in the configuration described in [5] above, The one-side attachment further includes a lower plate (44) that covers from below a space (54) defined by a lower surface (41) of the first inclined plate and a lower surface (43) of the second inclined plate.

[0054] According to the configuration described in [6] above, it is possible to prevent the transported object from entering the space and to suppress the first inclined plate and the second inclined plate from floating up.

[0055] [7] In some embodiments, in the configuration according to any one of [1] to [6] above, If the length of the gap in the intersecting direction is L1, the length of the one-side attachment in the intersecting direction is L2, and the length of the other-side attachment in the intersecting direction is L3, The relationships L1 / 3>L2>L1 / 5 and L1 / 3>L3>L1 / 5 are satisfied, respectively.

[0056] According to the configuration described in [7] above, each of the one-side attachment and the other-side attachment can be provided with the function of preferably pressing an object that has entered the side space.

[0057] [8] In some embodiments, in the configuration according to any one of [1] to [7] above, The plurality of chain links includes an attachment-less chain link (16) in which the one side attachment and the other side attachment are not installed.

[0058] According to the configuration described in [8] above, it is possible to prepare a number of chain links with attachments corresponding to the number of transported objects, thereby reducing the installation costs of the transport device.

[0059] [9] In some embodiments, in the configuration according to any one of [1] to [8] above, the at least one conveyor chain includes a first conveyor chain (2A) and a second conveyor chain (2B) spaced apart from the first conveyor chain in the cross direction and configured to be synchronized with the first conveyor chain; The chain links with attachments of the first conveyor chain and the chain links with attachments of the second conveyor chain are arranged so as not to overlap each other in the conveying direction.

[0060] According to the configuration described in [9] above, it is possible to prevent the first conveyor chain and the second conveyor chain from interfering with each other. Also, it is possible to reduce the number of chain links with attachments to be installed in the conveying device.

[0061]

[10] In some embodiments, in the configuration according to any one of [1] to [9] above, an upstream anti-compaction bar (70) disposed in the hopper above the conveyor chain and extending along the cross direction; A downstream compaction prevention bar (72) is disposed in the hopper above the conveyor chain and extends along the cross direction downstream of the upstream compaction prevention bar in the conveying direction, The downstream anti-compaction bar is located below the upstream anti-compaction bar.

[0062] According to the configuration described in

[10] above, the downstream anti-compaction bar further disperses the transported material dispersed downward by the upstream anti-compaction bar in the upward and downward directions. This enhances the effect of dispersing the transported material and suppresses compression of the transported material. [Explanation of symbols]
