Description

  The present invention relates to a conveyer facility for conveying, for example, steel slab generated when a hot-rolled steel plate is sheared.

  For example, when a hot rolled steel sheet on a rolling line is sheared as a product, chips after shearing, such as the front end, the rear end, and the left and right ends, may interfere with the next shearing work, Therefore, these unnecessary parts are removed from the line as scraps (so-called steel slab scraps, also called scrap) after being sheared and transported to a disposal site. And when conveying this chip to a disposal site, a conveyor equipment is generally used.

  For example, Patent Document 1 discloses a scrap conveyor facility for moving scrap from a steel plate processing line to the outside of the line and accumulating it at a predetermined place. The scrap conveyor facility includes a first belt conveyor that moves scrap from the steel plate processing line, a curve belt conveyor that turns the scrap by 90 °, and a second belt that moves the scrap received from the curve belt conveyor. Consists of a conveyor.

  Further, for example, Patent Document 2 discloses a belt conveyor that does not require a driving device to be provided on a rotating body such as a roller in a curved path when a transported object is transported. The belt conveyor disclosed in Patent Document 2 is also composed of a carry-in conveyor, a curve conveyor, and a carry-out conveyor, as in Patent Document 1.

  That is, for example, the conventional conveyor equipment used for transporting an object to be transported such as steel slab scrap as disclosed in Patent Documents 1 and 2 and the like may be configured by connecting a plurality of conveyors. It was general.

It is a schematic side sectional view of a conveyor facility. It is a schematic plan view of a conveyor facility. It is an expansion explanatory view of a swinging apron. It is expansion explanatory drawing of an idle roll, and has shown the state in which steel slab scraps are mounted on the idle roll.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present specification and drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 is a schematic sectional side view of a conveyor facility 1 according to an embodiment of the present invention. FIG. 2 is a schematic plan view of the conveyor facility 1. In the present embodiment, as will be described below, a conveyor facility 1 provided with one upstream conveyor and one downstream conveyor will be illustrated and described as an example. Further, as shown in FIG. 1 and FIG. 2, the slab waste W is conveyed from the left to the right, and the left side in the drawing is upstream in the conveying direction and the right side in the drawing is downstream in the conveying direction. Will be described.

  As shown in FIG.1 and FIG.2, the conveyor equipment 1 is equipped with the upstream conveyor 10 and the downstream conveyor 12 which convey the steel piece waste W which generate | occur | produces at the time of the shearing, for example at the time of commercializing a hot-rolled steel plate. Yes. On the upstream side of the upstream conveyor 10, for example, a shearing machine 5 for shearing hot-rolled steel sheets and the like is provided, and the slab waste W discharged from the shearing machine 5 is transported from the upstream conveyor 10 as a starting point. It is conveyed along L.

Moreover, the upstream conveyor 10 and the downstream conveyor 12 are adjacently arranged in series at a predetermined interval along a conveyance path of steel slab waste W (hereinafter, also referred to as a conveyance path L, see the one-dot chain line in the figure). Has been. Here, the conveyance direction of each conveyor is the same direction (right direction in the figure). In addition, the upstream conveyor 10 and the downstream conveyor 12 are chain conveyors that are connected to a plurality of chains to form a conveyor belt and are operated by a driving mechanism such as a motor.

  Further, as shown in FIG. 1, the upstream conveyor 10 is disposed at a position higher than the downstream conveyor 12 by a predetermined height. A swinging apron 20, a drive roll 24, a delivery plate 26, an idle roll 28, and a chute 30 are provided between the upstream conveyor 10 and the downstream conveyor 12 in order from the upstream along the transport path L. . That is, as shown in FIGS. 1 and 2, in the conveyor facility 1, the upstream conveyor 10, the swing apron 20, the drive roll 24, the delivery plate 26, the idle roll 28, A chute 30 and a downstream conveyor 12 are arranged. In addition, the facility (not shown) for discarding or storing steel slab waste is provided further downstream of the downstream conveyor 12.

  The swing apron 20 includes a top plate 21 on which the steel slab waste W transported from the upstream conveyor 10 is placed, a bracket 22 that supports the top plate 21 from below and is fixed integrally with the top plate 21, The rotary shaft member 23 is provided below the bracket 22 and supports the bracket 22 so as to be swingable in a direction perpendicular to the conveying direction. Here, as shown in FIG. 2, a plurality of brackets 22 are provided in the width direction of the conveyance path L, and one top plate 21 is integrally fixed to and supported by the plurality of brackets 22. It has a configuration.

Further, the direction perpendicular to the conveying direction is a direction perpendicular to the upper surface of the top plate 21 when the slab waste W is conveyed on the swinging apron 20, that is, the vertical direction. . Further, the upstream end 20a of the swinging apron 20 (that is, the upstream end 20a of the top plate 21) is in a swingable state and is in contact (placed) with the outer periphery of the upstream conveyor 10, so that the upstream side It is configured to swing together with the operation of the conveyor 10 (for example, the rotation of the chain in the case of a chain conveyor). Along with this swinging, the steel slab waste W on the top plate 21 also vibrates, and the steel slab waste W is easily transported.

Further, as shown in FIG. 1, the upstream end 20a of the swinging apron 20 (ie, the upstream end 20a of the top plate 21) is the downstream end 20b (ie, the downstream end 20b of the top plate 21). The swinging apron 20 is installed such that the top plate 21 is inclined at a predetermined angle θ with respect to the horizontal plane. Further, not only the top plate 21 but also a portion L ′ formed by the top plate 21, the rotary shaft member 23, the drive roll 24, the delivery plate 26, the idle roll 28, and the chute 30 in the conveyance path L shown in FIG. 1. Is also a predetermined angle θ. The inclination angle θ of L ′ that is a part of the transport path L is, for example, preferably 5 ° to 45 °, and more preferably 10 ° to 35 °. When the inclination angle θ is less than 5 degrees, the small steel slab waste W stays on the top plate 21 and remains, and there is a possibility that the conveyance is not performed efficiently. On the other hand, when the inclination angle θ is greater than 45 degrees, there is a problem that the gap between the upstream conveyor 10 and the top plate 21 is unnecessarily large during conveyance of the steel slab waste W, and the steel slab waste W falls. In addition, there is a problem that the steel piece scrap W slips too much due to a steep slope and damages the downstream conveyor 12. In the present embodiment shown in FIG. 1, the inclination angle of the portion L ′ formed by the top plate 21, the rotary shaft member 23, the drive roll 24, the delivery plate 26, the idle roll 28, and the chute 30 is all equal to θ. Although a case is described as an example, for example, the inclination angle of the portion of the chute 30 is 10 in comparison with other portions (top plate 21, rotating shaft member 23, drive roll 24, delivery plate 26, idle roll 28). Increasing by about 15 degrees is also conceivable.

  Further, a drive roll 24 for conveying the steel slab waste W is provided in the vicinity of the downstream end of the swinging apron 20, and this drive roll 24 is not connected to the downstream end 20 b of the top plate 21. In contact. The drive roll 24 is configured to be rotated by a drive mechanism (not shown), and conveys the steel slab waste W conveyed on the upper surface thereof downstream.

  An idle roll 28 is installed on the downstream side of the drive roll 24, and a delivery plate 26 for delivering the steel slab waste W is provided between the drive roll 24 and the idle roll 28. Yes. As shown in FIG. 1, the idle roll 28 is a roll that is rotatably supported, and the upper end of the idle roll 28 is installed at a position that protrudes upward relative to the upper surface of the transfer plate 26 and the upper surface of the chute 30 described later. Has been. That is, when the steel slab waste W moved in the downstream direction by the drive roll 24 is conveyed on the upper surface of the chute 30, the upper end portion of the idle roll 30 protrudes from the upper surface of the chute 30 (and the delivery plate 26). Therefore, it is possible to prevent the bottom surface of the steel piece waste W from sticking to the top surface of the chute 30 and hindering the conveyance.

  A chute 30 is installed downstream of the idle roll 28, and a downstream conveyor 12 is connected downstream of the chute 30. The chute 30 is configured such that its upstream end is positioned above the downstream end, and the steel slab W conveyed to the chute 30 is operated by the drive roll 24 arranged on the upstream side and the steel slab. The waste W is transported to the downstream conveyor 12 by its own weight. In addition, the steel piece waste W which is the scrap etc. which were conveyed by the downstream conveyor 12 is conveyed to the installation (not shown) for storing them.

  In the conveyor facility 1 according to the present embodiment configured as described above with reference to FIGS. 1 and 2, the slab waste W is dropped or caught between the upstream conveyor 10 and the downstream conveyor 12. Is prevented, and the steel piece waste W can be smoothly conveyed. The reason for this is that the rear end of the upstream conveyor 10 described above is located above the front end of the downstream conveyor 12 and there is a step between the two conveyors 10, 12, the swing apron 20, the drive roll 24, For example, an idle roll 28 is provided.

  FIG. 3 is an enlarged explanatory view of the swinging apron 20. As described above, the swing apron 20 includes the top plate 21, the bracket 22, and the rotating shaft member 23. The upstream end 20 a of the top plate 21 is in contact with the belt 10 a that is the outer peripheral portion of the upstream conveyor 10. On the other hand, the downstream end 20 b of the top plate 21 is not in contact with the drive roll 24. FIG. 3 shows a case where the upstream conveyor 10 is a so-called chain conveyor.

For example, when the upstream conveyor 10 is a generally known block-type chain conveyor, the belt 10a is configured by connecting a plurality of annular chains 10b. That is, the belt 10a has a shape in which some unevenness is formed along the outer periphery. Here, when the belt 10a is rotated to convey the steel slab W (when the upstream conveyor 10 is operated), the upstream end 20a of the top plate 21 that is in contact with the belt 10a has the unevenness. Along the vertical direction (direction perpendicular to the conveying direction). In other words, the top plate 21 slightly vibrates in the vertical direction when the steel slab W is conveyed. The small steel piece waste W conveyed on the upper surface of the swinging apron 20 by the swinging of the top plate 21 (that is, the slight vibration of the swinging apron 20) is prevented from staying on the transporting path and remaining (debris clogging). In addition, since the opening gap of the connecting portion can be minimized, the conventional problem that the slab waste W is caught and clogged is solved. Although the chain conveyor is illustrated and illustrated here as the upstream conveyor 10, the top plate 21 swings (fine vibration) even in the case of a general belt type conveyor. W catching is prevented.

  FIG. 4 is an enlarged explanatory view of the idle roll 28 and shows a state in which the steel piece waste W is placed on the idle roll 28. As described above, the idle roll 28 is disposed between the delivery plate 26 and the chute 30, and its upper end portion protrudes from the upper surfaces of the delivery plate 26 and the chute 30. Therefore, as shown in FIG. 4, the steel piece waste W is transported in a state where a gap 34 is formed between the transport path L (that is, the upper surface of the transfer plate 26 and the chute 30). As described above, in the conveyor facility 1 according to the present embodiment, the gap 34 is formed between the swinging apron 20 and the chute 30 between the steel piece waste W and the conveyance path (conveyance path L) as needed. Since the conveyance is performed, the problem that the steel slab W and the upper surface of the chute 30 stick to each other when the conveyance is performed without providing the idle roll 28 is avoided.

  As described above, in the conveyor facility 1 configured as described with reference to FIGS. 1 to 4, for example, when conveying steel slabs W weighing 100 kg or more, the upstream conveyor 10 and the downstream conveyor Since the swing apron 20, the drive roll 24, the idle roll 28, and the chute 30 are provided on the conveyance path between the upstream conveyor 10 and the downstream conveyor 12, the steel slab W is moved directly. Compared to the case, it becomes possible to prevent equipment breakage due to falling of the steel slab waste W onto the downstream conveyor 12 and dropping out of the conveying path, thereby realizing smooth conveyance and suppressing a decrease in productivity. it can.

  As described with reference to FIG. 3, on the upper surface of the swing apron 20, the top plate 21 swings (fine vibration) with the operation of the upstream conveyor 10. And the phenomenon that the steel piece waste W is caught on the conveyance path and becomes clogged by this rocking | fluctuation is prevented, and smooth conveyance can be implement | achieved.

  Further, as described with reference to FIG. 4, by providing the idle roll 28 on the conveyance path, the steel slab waste W is transferred to the upper surface of the conveyance path (for example, the upper surface of the chute 30 or the upper surface of the delivery plate 26). It is possible to prevent a situation in which the conveyance efficiency decreases due to sticking or clogging.

  As mentioned above, although an example of embodiment of this invention was demonstrated, this invention is not limited to the form of illustration. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the idea described in the claims, and these naturally belong to the technical scope of the present invention. It is understood.

  For example, in the said embodiment, the chip at the time of shearing the hot-rolled steel plate of 100 kg or more as steel piece waste W was illustrated. The conveyor equipment according to the present invention is particularly effective at the time of transporting heavy-weight scrap or the like, but is not limited to this, and can also be applied to equipment used when transporting all steel scraps.

  Moreover, although the conveyor equipment 1 concerning the said embodiment was demonstrated as a structure provided with all the rocking apron 20, the drive roll 24, and the idle roll 28, this invention is not limited to this, each What is necessary is just a conveyor installation provided with either of the components. For example, even when only the swing apron 20 is provided on the transport path, smooth transport of the steel slab waste W can be sufficiently realized.

  Moreover, although what was called a chain conveyor was illustrated as the upstream conveyor 10 and the downstream conveyor 12 with which the conveyor equipment 1 is provided, this invention is applicable also when using a general belt conveyor.

  The present invention can be applied, for example, to a conveyer facility for conveying billet waste generated when a hot-rolled steel plate is sheared.
