Description

[Detailed description of the device]

[0001]

[Industrial applications]

 According to the present invention, various types of powdery or granular materials such as coal and ore and bulk materials are discharged from the upstream transport means in two directions (that is, to separate conveyors) at a predetermined ratio. The present invention relates to a device for distributing a transportable product.

[0002]

[Prior art]

 Coal loaded in a stockyard (coal yard) is generally carried out by a reclaimer (commercial loader) or conveyer. In the process, coal from one yard is divided into two or more directions. May be sent. For example, if different types of coal are loaded in each yard and coal from two or more yards is mixed (blended coal), it is preferable to perform such distribution first. The coal in each yard is distributed in a specified amount, and each of the distributed coals is mixed.

Conventionally, in order to perform such distribution, coal is simply put in a hopper provided corresponding to each yard, and a fixed amount is cut out from two or more take-out ports formed in the hopper. For cutting, a device such as a belt feeder that can accurately control the amount (speed) of take-out is installed at each take-out port, and downstream of that, constant-feedware, conveyors, and other conveying means are connected. .

[0004]

[Problems to be solved by the device]

 The above-mentioned conventional distribution device is preferable in that coal can be discharged at an accurate distribution ratio, but since it requires a hopper, it becomes a large-scale structure, and it also includes cutting equipment and its control means. And the cost will be high. In addition, since the complicated procedure of transferring the coal in the stockyard to the hopper must be performed, it is preferable in terms of efficiency when quick distribution is required or when the type of coal to be distributed is changed. Absent. And, of course, these issues related to equipment composition and productivity are not only for coal, but for iron ore, limestone and other powders or similar bulk materials in two directions. It occurs commonly when you do.

An object of the present invention is to provide a dispensing device that can dispense powder and granules or the like in two directions at a predetermined ratio without requiring a hopper or a special cutting device.

Japanese Utility Model Laid-Open No. 60-137732 discloses a distribution device that can be used to form a pile having good symmetry when iron ore or the like is stacked. However, even though the device distributes powder and granules, it cannot be used for the intended purpose of the present invention because it does not control the amount and ratio of distribution.

[0007]

[Means for Solving the Problems]

 The distribution device for conveyed goods according to the present invention is a distribution apparatus for discharging conveyed goods such as powder and granules sent from upstream conveying means (conveyor, transport pipe, vibrating feeder, etc.) in two directions. a) A chute with two adjacent inlets and separate outlets connected from each inlet, b) A position adjustment in the direction in which both inlets are lined up (adjacent to each other) is possible, and the delivery of the upstream side transport means is performed. Placed underneath the section-the one.

In this distribution device, further, as described in claim 2, c) the two delivery ports are connected to the respective conveyors via a fixed delivery path, and d) the load detection means for each conveyor. In addition to the above, the e) chute is preferably provided with drive means for adjusting the position in the above direction based on the output of the load detection means.

[0009]

[Action]

 When the distribution device according to the present invention is arranged following the upstream conveying means such as a conveyor, it distributes the conveyed objects (powder particles, etc.) from the conveying means in two directions at a predetermined ratio as follows. To do.

First, as described in a) above, the device of the present invention includes a chute in which two input ports are adjacent to each other and separate output ports are provided. Since the input port of this chute is located below the delivery part of the upstream side transport means as shown in b), the goods transported from this means enter the two input ports separately, and the payouts connected to each of them. It is paid separately by mouth. And, for example, if the chute is arranged so that the intermediate part (partition plate, etc.) of the two inlets is on the center line of the transfer means, under normal conditions (such as when there is no bias in the transfer state of the transfer means). ) One-half of the amount transported by the upstream-side transport means uniformly enters each input port, and is distributed from each dispensing port to the downstream-side transport means, etc. at an equal ratio.

[0011] The conveyed product from the upstream side conveying means is not always conveyed symmetrically with respect to the center line of the means, and is not symmetrically fed into the apparatus, but in the apparatus, the above b) is used. As described above, since the position of the chute can be adjusted, the distribution ratio can be maintained at a predetermined value regardless of such circumstances. For example, if the goods to be transported tend to be biased to one side with respect to the center line of the carrier, the chute is positioned near the center of the actual carrier instead of the middle of the two inlets being on the center line of the carrier. As you can see, I will shift them in the direction in which both inlets are lined up. By appropriately adjusting the position of the chute in this way, the distribution ratio of the conveyed products in the two directions can be almost matched to a predetermined target. Since unevenness and irregularity of the conveyed items in the upstream conveying means occur irregularly and accidentally, even if such adjustment is performed, it is not possible to prevent the irregularity of the distribution ratio instantaneously, but a large amount of conveyed items takes a considerable amount of time. When the product is transported and distributed over time, the overall distribution ratio in terms of the integrated amount is very close to the target value.

In the distribution device according to the second aspect, the position adjustment of the chute as described above is automatically performed. This is because each of the downstream side conveyors connected from each outlet as in c) above is provided with a load detecting means as in d), and the driving means in e) is fed while feeding back the output. This is because the position of the chute is automatically controlled. Specifically, for example, when the load on one conveyor increases compared to the other, the detection means in d) detects this, and the position of the chute is adjusted so that the number of conveyed objects on the increased conveyor decreases. Is adjusted by the driving means of e).

In the apparatus according to the second aspect of the present invention, since each payout opening of the movable chute whose position can be adjusted is connected to each conveyor via the fixed payout path as described in c) above, Also acts like. In other words, if a fixed delivery path is formed in a bifurcated manner across two conveyors, the above-mentioned chute, which is a moving member, can be made compact and lightweight, and its drive means, etc. can be made compact and small in capacity. it can. In addition, since the goods are delivered to the downstream conveyor via a fixed delivery path that does not move, the chute is moved in the moving direction (this is determined by the type and arrangement of the upstream conveyor). There is no limitation, and the arrangement direction of the conveyor can be set freely.

【Example】

 An embodiment of the present invention will be introduced with reference to FIGS. This example relates to the discharge of coal from a stockyard (not shown), and Fig. 3 schematically shows the arrangement of distribution equipment and related equipment.

The coal piled up in the stockyard is carried and carried on the yard conveyor 2 of FIG. 3 which is a belt conveyor by a loading device such as a reclaimer (not shown). Distributor 1 divides the supplied coal into halves and delivers them to the two downstream conveyors 3 and 4. On the other hand, also in another stockyard where different types of coal are piled up, the same yard conveyor 102 is arranged together with a reclaimer (not shown) to convey the coal, and a distribution device 101 of the same type as the distribution device 1 is installed. It is distributed to the downstream conveyors 103, 104. A certain amount of specific types of coal from each stockyard is thus carried out in two directions in order to carry out the required mixed coal at two locations (for example, on each belt of conveyors 103 and 104) at the same time. That is, the amount of conveyance per unit time by each yard conveyor 2 · 102 is made constant, and the distribution ratio to each of the two directions by each distribution device 1 · 101 is set to ½, and then the conveyor 3 · 103 If the coals carried out are mixed together, while the coals on the conveyors 4 and 104 are mixed together, the same amount of the same amount of coal can be mixed at two locations simultaneously.

In order to perform proper blending, it is premised that the distribution devices 1 and 101 distribute coal to the conveyors 3 and 4 or the conveyors 103 and 104 at a fixed ratio, respectively. The 101 is configured as follows for that purpose. Since the distribution devices 1 and 101 have the same format, only the distribution device 1 will be described below.

As shown in FIG. 1, a main part of the distributor 1 is a movable chute 10 provided immediately below a delivery part (tip part) of the yard conveyor 2 and a driving means for moving (position adjusting) the chute 10. 20 and a payout path 30 continuously arranged under the chute 10. Further, as shown in FIG. 3, scales (load detecting means) 41 and 42 are attached to the conveyors 3 and 4, respectively, and a feedback signal having a magnitude corresponding to the carrying load is output to the driving means 20.

The chute 10 is a kind of passage through which coal passes up and down while guiding the falling direction. As shown in FIG. 2C, the chute 10 is provided with two inlets 11 and 12 adjacent to each other at the upper end. At the same time, as shown in (b), dispensing ports 13 and 14 connected to the respective charging ports 11 and 12 are formed in the left and right at the lower end. The space between the two inlets 11 and 12 and the outlets 13 and 14 is partitioned by a partition plate 15 shown in (b) and (c). Since the edge of the upper end of the partition plate 15 is constantly in contact with coal from the yard conveyor 2 to be introduced as described later, a hard steel material having high wear resistance is attached. Further, as shown in FIGS. 1A and 1B and FIG. 1, a plurality of rotatable rollers 16 are attached to the outside of the chute 10, and the rollers 16 are aligned with the guide rails 8 installed on the steel frame support frame 7. The shoot 10 is freely movable. The direction of movement of the chute 10 is the direction of the guide rail 8 and the direction perpendicular to the paper surface of FIG. 2 (b) (left and right in FIG. 2 (a)), but this direction is the insertion port 11.12 in the chute 10. It is made to coincide with the direction in which is aligned, that is, the direction perpendicular to the partition plate 15.

As shown in FIG. 2 (a), a transmission chain 24 is stretched around the side surface of the chute 10 by a driving side sprocket 22 and a driven side sprocket 23, and a part of the chain 24 is attached to a metal fitting 24 a (see FIG. 1). It is connected to the side surface of the chute 10 via the reference. The longitudinal direction of the chain 24 corresponds to the left and right of FIG. 2A, that is, the direction in which the chute 10 can move. The sprocket 22 on the drive side is mounted on the output shaft of the prime mover 21 including the motor and the speed reducer / control device. Therefore, the movable chute 10 having the rollers 16 uses the prime mover 21, the sprockets 22 and 23, the chain 24, etc. as the driving means 20, and moves in the above-mentioned direction as the chain 24 circulates to move its position. Adjustments can be made. The range in which the chute 10 can move includes the state in which the partition plate 15 is on the center line of the conveyor 2 (within the vertical plane including the center line) as shown in the drawing, and the inlets 13 and 14 are provided directly below the delivery section of the conveyor 2. Only one can be located respectively. The position of the chute 10 is determined within this range in accordance with the target distribution ratio, and as described later, in association with the uneven distribution of coal on the conveyor 2.

The chute 10 is a compact one in which the payout ports 13 and 14 are short and does not reach the conveyors 3 and 4 on the downstream side. Therefore, as shown in FIG. Is installed, and the openings 32 and 33 of the bifurcated lower end portions thereof are located above the conveyors 3 and 4, respectively. The outlets 13 and 14 of the chute 10 are inserted into the opening 31 at the upper end, but the lower ends of the outlets 13 and 14 are arranged so that the coal divided into the outlets 13 and 14 can be sent to the openings 32 and 33 as they are. As shown in FIG. 2 (b), the payout path 30 is inserted into a bifurcated portion. While the chute 10 moves to adjust the position, the payout path 30 is fixed to the steel frame 7 so as not to move from a fixed position on the conveyors 3 and 4. Therefore, the size of the opening 31 at the upper end is increased. Has a size that allows the chute 10 to move within the above range by inserting the payout ports 13 and 14.

Now, in the distribution apparatus 1 configured as described above, the coal conveyed by the yard conveyor 2 and charged from the delivery section at the tip thereof is transferred to the conveyors 3 and 4 at a constant ratio as follows ( In this example, one half is evenly distributed.

The chute 10 is set at the center position, that is, the partition plate 15 is positioned so as to overlap the center line of (the belt 2 a of) the conveyor 2 and the conveyor 2 is started as shown in FIG. Coal from the conveyor 2 enters the chute 10 into the inlets 11 and 12 separately, passes through the outlets 13 and 14 and further passes through the outlet route 30 to the conveyors 3 and 4 through the openings 32 and 33, respectively. Be paid out.

When coal tends to be placed on the belt 2a of the conveyor 2 in one direction with respect to the center line, the amount of coal distributed to the conveyors 3 and 4 via the chute 10 and the like is not uniform, In that case, the drive means 20 adjusts the position of the chute 10. For example, when the load of the conveyor 3 (the amount of coal) is larger than that of the conveyor 4, the drive means 20 moves the chute 10 to the left in FIG. In this way, the inlet 11 is slightly off the center line of the conveyor 2 and the amount of coal entering it is a little smaller than before, so the amount of coal reaching the conveyor 3 via the outlet 13 and the opening 32 is also reduced. On the contrary, the amount of coal to the conveyor 4 that is increasing is close to that. Such movement of the chute 10 causes the prime mover 21 of FIG. 2 (a) to move the chain 24 by an appropriate amount based on the signals from the scales 41 and 42 (see FIG. 3) provided on the conveyors 3 and 4. Done automatically by.

Since the unevenness and dispersion of coal on the conveyor 2 usually change with time, the position of the chute 10 is adjusted, for example, every few minutes. That is, the drive means 20 corrects the position of the chute 10 by checking the signals of the scales 41 and 42 every time when all the coals on the conveyors 3 and 4 are replaced. The position of the chute 10 may not be adjusted by the load itself at each moment, but may be adjusted based on a value (integral value) obtained by integrating the conveyor load for each unit time. If such control is continued during operation, the distribution ratio of the distribution device 1 to the conveyors 3 and 4 will be approximately exactly one half each.

The distribution device 101 in FIG. 3 also similarly distributes the coal from the yard conveyor 102 onto the conveyors 103 and 104, and that each of the distributed coals is mixed in two places. It is as follows.

[0026]
