Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to lumps such as coal, granules and powders such as grains (
The present invention relates to a dispensing device that moves back and forth in a straight line for discharging stored matter (hereinafter referred to as stored matter) from stored matter equipment such as a silo.

[Prior art] A movable stored material dispensing device having a discharge port at the bottom and repeating linear reciprocating motion is provided at the discharge port, and the stored material discharged by the dispensing device is conveyed below the dispensing device. The applicant previously filed a patent application for a storage facility equipped with a transport bag device such as a conveyor for
No. 252).

According to this technology, the stored material can be discharged stably without clogging the discharge port unlike conventional stored material equipment in which the discharge port is provided with an on-off valve or the like.

[Problems to be solved by the invention] By the way, in the stored material equipment for which the patent was previously applied, the conveyor or other conveyance device is operated at a constant speed in one direction (forward direction), whereas the mobile stored material dispensing device is operated at a constant speed in one direction (forward direction). The device has two directions (forward and
Since the moving device is operated at a constant speed in the opposite direction (reverse direction), the relative speed of the mobile stored material dispensing device to the conveyance device during forward and reverse transportation is different. However, in reality, the transport load capacity of the transport device at the dispensing port section is different when the mobile stored material dispensing device is in normal operation and in reverse operation.

For this reason, in conventional apparatuses, in order to ensure the conveying capacity of the conveying apparatus at the dispensing port, the capacity of the conveying apparatus is determined according to the slower relative speed.

However, when the speed of the transport device is constant, the transport capacity of the transport device must be changed by changing the transport width. In an actual machine with a speed of 10 m/min, the relative speed ratio of the mobile accumulated material dispensing device to the conveying device during forward and reverse operation is 1°4, so the belt width must be made 1.4 times wider. The length of the transport device is generally as long as 50 to 100 m, and as the transport width increases, the price inevitably increases and the installation space increases, resulting in a significant loss.

[Structure of the Invention] The present invention has been made to solve the above-mentioned problems of the conventional art, and does not require any intervention in a conveyor or other conveyor for conveying the stored material dispensed by the mobile stored material dispensing device. By simply adding a mechanism that changes the dispensing amount of the mobile accumulated material dispensing device in relation to its reciprocating motion, the capabilities of the conveying device can be fully utilized during both the forward and backward movements of the dispensing device. This is how it was done.

That is, according to the present invention, a mobile stored matter dispensing device 4 having a discharge port at the bottom and dispensing stored matter by repeating a linear reciprocating operation is provided at the discharge port, and a discharge device 4 is provided below the dispensing device 4. In a storage equipment installed with a conveying device 5 that travels in one direction for conveying stored materials discharged in an amount of A mobile stored material dispensing device is provided which is configured to reduce the dispensing amount when moving in the forward direction moving in the same direction (and increasing the dispensing amount when moving in the backward direction moving in the opposite direction to the traveling direction of the conveying device 5). be done.

Further, in carrying out the present invention, the movable stored material dispensing device 4 has a pair of planar dogleg-shaped parts that mutually rotate at the bending part so that one side is opened to the dispensing position and the other side is closed to the neutral position. The dispensing device 4 is equipped with scrapers 8a and 8b, and the dispensing device 4 reduces the opening angle of the scrapers 8a and 8b during forward movement in the same direction as the traveling direction of the conveying device 5. , the opening angle of the scrapers 8a and 8b is increased to increase the amount of scraping when the conveying device 5 moves in the opposite direction to the traveling direction.

Furthermore, in the embodiment of the present invention, the height of the scraper 8a18b on the backward moving side of the dispensing device 4 moves in the opposite direction to the traveling direction of the conveying device 5, and the height thereof moves in the same direction as the traveling direction of the conveying device 5. Scrapers 8a, 8 on the forward moving side
It is assumed that the height is set higher than the height of b, and that the payout m when the payout device 4 moves in the backward direction is larger than the payout when the payout device 4 moves in the forward direction. For this, scraper 8a18
Height adjusting plates 15a and 15b are attached to the scrapers 8a and 15b so as to be adjustable, so that the heights of one side and the other side of the scrapers 8a and 8b can be changed.

[Operation of the invention] The conveyor Vt@4 such as a conveyor travels in one direction (forward direction) at a constant speed. On the other hand, the mobile stored product dispensing device 4 moves at a constant speed in two directions (forward and reverse directions). The scrapers 8a and 8b with the dispensing amount @4 open on the moving direction side of the dispensing device 4 and become the dispensing position, and take out the accumulated material from the stored material equipment 1 such as a silo, and the accumulated material discharged by the dispensing device 4 is transferred to the conveying device@ 5 and is transported to an appropriate location outside the storage equipment 1 by the transport device 5.

When the moving direction of the dispensing device 4 shown in FIG. 4(a) is in the same direction as the traveling direction of the conveying device 5, the opening angle of the scrapers 8a and 8b is made relatively small, and the dispensing amount by the dispensing device 4 is Relatively few. Further, when the dispensing device 4 is moved in the opposite direction as shown in FIG. There will be more targets. This means that the scrapers 8a and 8 shown in FIG.
This can also be achieved by changing the height of the scrapers 8a, 8b between the forward movement side and the reverse movement side of the dispensing device 4 using height adjusting plates 15a, 15b attached to the ends. As a result, the capacity of the conveying device 5 can be fully utilized even in the stored material equipment 1 equipped with the reciprocating stored material dispensing device 4 in which the relative speed of the dispensing amount @ 4 to the conveying device 5 during forward and reverse travel is different. .

[Example] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a stored material facility with a built-in mobile stored material dispensing device, where 1 is a silo main body having a discharge port at the bottom, and 2 is a cone provided above the discharge port.

The rail extends in the longitudinal direction of the silo 1, and a pair of running rails 3a and 3b are installed therein.

A mobile stored material dispensing device is designated as a whole by 4, and is suspended from running rails 3a and 3b via its running wheels and travels back and forth. Reference numeral 5 denotes a conveying device, that is, a conveyor. The conveyor 5 is installed below the dispensing amount M4, and is adapted to convey the accumulated material dispensed by the dispensing device 4, and moves in the direction of the arrow.

FIGS. 2 and 3 show the details of the mobile stored material dispensing device 4, in which the traveling wheels 6 that move on the traveling rails 3a and 3b are driven by a traveling wheel 97, and the traveling motor 7 is set at the limit in the reverse position. [- The rotation is switched between forward and reverse rotation by a switch or the like, so the payout amount M4 travels back and forth.

A pair of planar dog-shaped scrapers 8a, 8b/+'aQ are provided at the bottom of the mobile stored material dispensing device 4, and constitute a dispensing means. Shafts 9a and 9b rotatably supported on the machine frame at the
are fixed respectively.

Also, @9a and 9b have sector gears 10a that mesh with each other.
, 10b are fixed, and further one of the axes,
For example, an adjustment arm 11 is fixed to the shaft 9b. A lobe 12 is connected to the tip of the adjustment arm 11, and the lobe 112 is wound around drums 13a and 13b provided on both sides of the dispensing device 4, and the drums 13a and 113b are driven by motors 14a and 14b, respectively. It is designed to be rotated. Therefore, in FIG. 3, when one of the drums 13a rotates in a direction that involves the row 112, the scraper 8a is
, 8b has its right half open to serve as a payout position, and its left half to close to serve as a neutral position. The other drum 13b is the lobe 1
2, the left half of the scrapers f3a and f3b opens to take the dispensing position, and the right half closes to take the neutral position.

Of course, the side where the scrapers 8a and 8b are in the open dispensing position is the moving direction side of the mobile stored material dispensing device 4, but this switching is possible from the forward direction of the dispensing device 4 to the reverse direction.
This is done in conjunction with the switching from the reverse direction to the forward direction.

For this purpose, the motors 14a and 14b of the scrapers 8a and 8b are alternately operated in conjunction with the travel motor 7 that drives the dispensing device 4 being switched from forward rotation to reverse rotation and from reverse rotation to forward rotation by a limit switch or the like in the reverse position. It is only necessary to rotate the lobe 12 in a direction that involves the lobe 12.

By the way, as mentioned above, the conveyor 5 operates in one direction (positive direction).
While the mobile stored material dispensing unit @4 is operated at a constant speed in two directions (forward and reverse directions), the dispensing device 4 is operated in the forward and reverse directions relative to the conveyor 5. Therefore, the conveyance capacity of the conveyor 5 at the dispensing port section differs between when the dispensing device 4 is in normal operation and when it is in reverse operation.

That is, when the mobile stored material dispensing device 4 moves in the forward direction (the direction in which the conveyor runs), the relative speed with respect to the conveyor 5 is small, and when the dispensing device 4 moves in the opposite direction (in the direction opposite to the direction in which the conveyor runs), the relative speed is small. The relative speed with the conveyor 5 increases. Now, the dispensing amount of the dispensing device 4 is the same both during the reciprocation, and the conveyance capacity of the conveyor 5 is set to the conveying capacity when the dispensing device 4 moves in the forward direction (the running direction of the conveyor). When the conveyor 4 moves in the opposite direction (the direction opposite to the running direction of the conveyor), the conveyance capacity of the conveyor 5 is too large and it is uneconomical. Otherwise, when the dispensing device 4 moves in the forward direction, the dispensing amount will exceed the conveyance capacity of the conveyor 5.

Therefore, as shown in FIGS. 4(a) and 4(b), the opening angle (opening width) of the scraper 8a18b is changed when the mobile stored material dispensing device 4 moves in the forward direction and when it moves in the reverse direction. That is, when the payout layer @4 shown in FIG.
, 8b are made small, the scrapers 8a and 8b pay out a relatively small width X with the accumulated material, and the payout layer is relatively small. Also, the dispensing device 4 is not shown in Fig. 4 (b).
When moving in the opposite direction to the traveling direction of 5, use the scraper 8.
Increase the opening angle of a18b and scraper 8a, 8b
The stored material is dispensed with a relatively large width Y, and the interval between dispensing is relatively large. In order to change the opening angle of the scrapers 8a and 8b in this way, the row 11 by the drums 13a and 13b is
2 may be changed in relation to the movement of the dispensing device 4 in the forward and reverse directions.

In addition, in order to change the dispensing amount of the movable stored material dispensing space @4 in relation to its forward/reverse movement, height adjusting plates 15a, 15b are attached to the scrapers 8a, 8b as shown in FIG. This can be done by changing the height of the adjusting plate 15a115b. In other words, the height of the scraper on the opposite direction movement side where the dispensing device 4 moves in a direction opposite to the traveling force of the conveying device @5 is adjusted by adjusting plates 15a and 15b so that the dispensing device 4 moves in the same direction as the traveling direction of the conveying device E5. The height of the scraper is set higher than the height of the scraper on the forward moving side to increase the amount of discharge. In this case, the opening angles of the scrapers 8a and 8b can be made the same both when the dispensing device 4 moves in the forward and reverse directions. The height adjustment of the adjustment plates 15a, 15b may be performed manually or automatically.

[Effects of the Invention] As explained above, according to the present invention, the mobile stored material dispensing device reduces the dispensing interval when moving in the forward direction in which it moves in the same direction as the traveling direction of the conveying device. Since the amount of dispensing is increased during multi-directional movement in the opposite direction to the traveling direction, the dispensing device is always stored at its full carrying capacity even if the relative speed of the dispensing device to the conveying device differs during forward and reverse movement. Objects can be taken out and stored objects can be transported efficiently. In this case, according to the present invention, the opening angle of the scraper of the dispensing device is changed in relation to the forward/reverse movement of the dispensing device without any modification to the conveying device (first embodiment); This can be done by simply changing the height of the height adjustment plate in relation to the forward and reverse movement directions of the dispensing device (second embodiment), and the desired purpose can be achieved with a simple mechanism. It is something.
