JPS5863629A - Put-out device at circular put-out opening - Google Patents

Abstract

PURPOSE:To provide a put-out device which can improve efficiency of putting out without detracting opening and closing functions of a put-out opening by rotating a scraper to be displaced between an opening and closing gate of the circular put-out opening and a position for vertically wrapping the gate or a position not to wrap it. CONSTITUTION:A gate 5 is supported on the periphery of a circular put-out opening A in such a manner as to move up and down, and a scraper 9 is fixed on a rotary ring 8 disposed in the periphery of a table 3 by a shaft 14 in such a manner as to rotate horizontally. A rotation applying device comprising a spring 15 and a stopper 16 is interposed between the ring 8 and the scraper 9. In case of put-out operation, when the gate is drawn up to open the put-out opening, granular powder 4 in a hopper 1 is lowered to stop on the table 3. Subsequently, when the ring 8 is rotated in the direction of X, and a table 11 is rotated in the direction of Y, the scraper stopped by a stopper 16 at a position not apart from the table 3 is pushed against the granular powder, thereby to scrape off granular powder on the table 11. The scraper is further advanced from the gate 5 into the put-out opening by its reaction force produced by striking on the granular powder so as to improve put-out efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dispensing device from an annular dispensing opening.

Conventionally, as shown in FIG. 1, *, centered on center 1IIB.

A shaped outlet is made by inserting a conical cone 2 into the lower large diameter opening of the hopper 1. The lower part of the corn 73 is horizontally protruded and serves as the table 3. For this reason, the powder and granules stored in the hopper 1 can flow out from the four discharge outlets onto the table 3 and stay on the table 3 while maintaining the angle of repose. A gate 5 is supported by a cylinder device 6 so as to be movable up and down around the dispenser. When this gate 5 is also lowered by the cylinder device, the delivery port is closed to prevent entry of hot air from the delivery port, including foreign matter and air that accelerates the oxidation of the S grain number.

As a conventional example of dispensing the powder or granular material 4 that has remained on the table 3, the following device has been proposed.

That is, as shown in FIG. 181, a plurality of scrapers 9 are fixed to the scraper ring S, which is rotated around the center 1IBt by the motor 7, in an arrangement such that the center 11 thereof extends above the table 3. For this purpose, the granular material 4 on the table 3 becomes a scraper 9 that rotates together with the scraper ring a! !
The tape is scraped downward from the outer periphery of tape #3. scratch**
The center line B is located at the position where the powdered material 4 is received.
It has a revolving table n which is driven to rotate around the revolving table, and as the revolving table n rotates, the powder 4 received on the revolving table U is moved from the floor to the fixed scraper which is fixedly supported. Then, the powder 4 is scraped onto the fixed scraper and onto the conveyor n. After that, it is transported to the destination on a conveyor. With such a dispensing a & device, the opening width of the dispensing outlet car is widened and the scraper 9
As shown in No. 2E, put it into the outlet A and scrape it with a scraper, as well as saturate the fluidity of the powder and granules.
1ll efficiency, that is, the dispensing aSt ability, is improved, but there is a drawback that it interferes with the scraper 9 and is slowed down by lowering the gate i, which is eliminated by closing the dispensing outlet car.

The purpose of the present invention is to improve the performance of dispensing from the dispensing opening of an SL fall type without impairing the opening/closing function of the dispensing opening.

The key points of Kibatsu are its basic configuration: a prize-shaped payout port,
(closing the said dispensing port) and ma from the dispensing port
a thick table that receives and stops the waste, and a scraper that stays on the table and scrapes off the waste.
and a scraper ring that supports the scraper and rotates around the table, wherein the scraper is horizontally rotatable to the scraper ring.
A reward shape characterized in that the scraper is attached and supported between the scraper and the scraper ring, and the scraper is rotated in a direction away from the dispensing opening, and the rotation imparting device is set in the JtJ11 direction. It has a device for dispensing from the dispensing port, and when closing the dispensing port, the scraper is rotated and retracted from the dispensing port in the direction toward which it reaches, and when dispensing, the scraper is rotated toward the dispensing port and moved toward the dispensing port (51!). It's at a turning point.

Each embodiment of the present invention will be described below with reference to FIGS. 3, 4, and 5.

#! As shown in Figure 4, the center! It is made by inserting a conical cord 72 into the lower large-diameter opening of the prize-shaped outlet A and hopper 5 centered on IB. The lower part of this cone 2 is protruded horizontally and serves as a table 3 for retaining the granular material 4 in the hopper l. A company gate 5 is supported around the payout car by a cylinder device so as to be able to move up and down. The scraper ring l placed around the table 3 can be freely driven by a hexameter, 7, jl*wA around a center line B.

A scraper A 9 is horizontally rotatable to apply salt 9 to the scraper ring 8 by means of a straight rotating shaft 14.

Between the scraper link 8 and the scraper 9, as shown in FIG. 3, a rotation imparting device consisting of a spring spring and a stopper is installed. One end of the spring is connected to the scraper 9, and the other end is connected to the scraper ring 8, and a tensile force is applied to the spring in advance. The stop flange 16 is such that -jIIl is fixed to the scraper ring opening, the other end is in a range where the rotation area of the scraper 9 does not come off the top of the table 3, and it can be regulated within %/-kIIIl without overlapping with the gate S above and below. It is arranged in a central position.

A thick rotating table U centered on a center line B is installed below the table so that it can be rotated freely by a peak W. A fixed scraper protruding onto the rotating table U is fixedly supported from the floor. The floor has a conveyor l in a fixed scrape/(19) lower pipe arrangement.

As a rotation imparting device, instead of a spring spring, a turnbuckle device 17 is used to connect the scraper ring opening and the scraper, as shown in FIG.

In this case, since the turnbuckle device 17 has the function of a stopper, a stopper is not necessary.

Next, each operation will be explained.0 When the dispensing operation is paused, the scraper 9 is pulled to the scraper ring by the spring, so the scraper 9 roars to the stopper. rotation axis 1 until
It automatically rotates around 4 and retreats from the entrance side of the payout port. Then, the gate device is lowered by the cylinder device 6 and the payout car is closed.

Next, when performing the dispensing operation, pull the gate 2 up by a few cylinders to move the dispensing ROM. When you open the payout ROM, a hopper will appear from this payout ROM! The granular material 4 inside falls by gravity and comes out onto the table S, which maintains the angle of repose at the table 3 circle and produces overtones. After that, the motor 1 rotates the scraper ring l in the direction of the X arrow in No. 5 m11, and the
Rotate the turning table U in the direction of the Y arrow using the lever. In this way, the scraper 9 is stopped by the stopper lug at the position i where it does not come off the table 3 as shown by the two-dot chain line in No. 3E. [Press the powder] and scrape the powder 4 onto the rotating table U. Due to the reaction force of the scraper powder 4 and the screw 9, it rotates around rotation -14 in the direction of the dispensing ROM against the spring force. Therefore, automatically Shima,
Like the scraper 4 all, the gate 5 also enters the payout port A side, thereby improving the scraping efficiency, that is, the payout efficiency. To the turning table U! As the granular material 4 and the rotating table n rotate, the fixed scraper scrapes it onto the surface of the conveyor. The powder and granular material 4 is transported by this conveyor 13 toward the destination.

Next, when stopping the dispensing operation again, the motor 1 is stopped. If the spring 7 is in the ζ state and has the power to rotate the scraper 9, which roars and cracks with the powder and granules 4, with a screw on the door, it will stop the 11% of the scraper 9. When the scraper 9Fi is pressed, it will automatically evacuate to a range where it does not overlap up and down with force. ring 1
Rotate it in the direction of the anti-X arrow. In this way,
Powder 4 on table 3 is insect 1 on the back side of the scraper.
As a result, a force is generated that pushes the scraper assembly away from the dispensing rom. Therefore, it is possible to retreat to a position where it does not overlap vertically with Scra I (9 is automatically pressed) without relying on the natural tension of the spring.

After that, the gate device is lowered by the cylinder device 1 to close the dispensing ROM, and then the mine 1 is stopped.

As the rotation imparting device, as shown in No. SaO, a turnbuckle device 11 is adopted, and in a large case, the scraper 9 is rotated by rotating the nut seat part of the turnbuckle device 1.
can be rotated around the rotating shaft 14.

As described above, in the present invention, since the scraper is rotated between the opening/closing gate of the annular dispensing port and the position where it is vertically/legged and the i position where it is not bent, it becomes hot. The effect of improving the dispensing efficiency without impairing the function can be obtained.
