Description

  The present invention includes a charge container that is reciprocally driven by a reciprocating drive device that is movable in the horizontal direction in order to supply a compounding raw material to a brick press apparatus, and a rotary compounding that agitates the compounding material supplied in the charge container The present invention relates to a raw material supply apparatus.

The present applicant discloses a blended raw material supply apparatus for producing a high-quality brick by supplying a uniform blended raw material to a metal frame of a brick press apparatus (for example, see Patent Document 1).
Also, a rotary charger that stirs an appropriate amount of the blended raw material in a blending container in advance and supplies the blended raw material to the metal frame while rotating the stirring blade in order to increase and maintain the uniformity of the uniformly stirred raw material. Is disclosed (for example, see Patent Document 2).

4 and 5 show simplified views of the form of the rotary charger A19. 4 is a side sectional view of the rotary charger A19, and FIG. 5 is a top view thereof.
A suitable amount is supplied from the hopper A21 at the upper part of the container body part A14 by the belt conveyor 39 from the hopper 26 storing the blended raw material G in the upper right part of FIG. The blended raw material G in the container body part A14 is charged up to the upper part of the metal frame 16 at the bottom of the brick press (not shown) while being stirred by a rotary blade A3 driven by a motor M attached to the outside of the container body part A14. The upper surface of the table A13 is moved in the X1 direction (direction of the metal frame 16) by the piston Ps of the cylinder Cy. Here, the rotary charger A19 that has supplied the blended raw material G to the metal frame 16 moves in the X2 direction (the hopper 26 direction) and starts the supply operation again.

  In this way, the piston Ps is expanded and contracted at the upper part of the extraction plunger 18 at the normal position of the brick press device, that is, the position of the rotary charger A19 in FIG. The compound raw material G is supplied to the cavity S. And the mixing | blending raw material G is pressurized with the pressurization plunger which is not illustrated in the upper part of a brick press, and a brick is shape | molded.

In the above process, the stirring blade Ab at the tip of the rotary blade A3 of the rotary charger A19 is a plate-like body, and the deflection rigidity with respect to the rotational resistance cannot be greatly increased, and because it is one direction like the counterclockwise rotation Ra in FIG. Stirring of the blended raw material G was not necessarily uniform, unevenness occurred in the container body A14, the blended raw material height H in FIG. 4 was not constant, and the supply and filling amount to the metal frame 16 was nonuniform. As a result, there was an example in which the formed brick had an error of about ± 1 mm with respect to the fixed thickness.
In order to eliminate this thickness error, the pressing force applied to the blended raw material G was adjusted, but there was a problem that the specific gravity of the molding rocks.
FIG. 6 shows an example in which the rotary charger A19 is doubled in order to improve workability.

As another conventional technique, a rotary pan type kneader used mainly for kneading raw clay for producing refractory bricks is disclosed (for example, see Patent Document 3).
Japanese Patent Application No. 10-205014 JP 2000-326317 A No. 7-42653

  The present invention has been proposed in view of the above-mentioned problems of the prior art, and increases the uniformity of the blended raw material, which is a problem when the compounded raw material is pressure-molded with a metal frame, to increase the thickness at the time of molding. The purpose is to provide a rotary-type blended raw material supply device that is constant and has no fluctuation in bulk density.

  As a result of various studies, the present applicant has rotated the rotating blade for stirring horizontally with a plurality of rod-like bodies suspended in the blended raw material instead of the conventional plate-like body, and forward, reverse, and rotation. It has been found that improving the rigidity of the wings makes it possible to make the blended raw material more uniform as if the rice for sushi is stirred with fingers. The present invention has been created based on such knowledge.

  According to the present invention, a charge container 19 is provided that is reciprocally driven by a reciprocating drive device Cy that is movable in the horizontal direction in order to supply a blended raw material to a brick press apparatus that supplies a blended raw material to the brick press apparatus. In the rotary-type compounding material supply apparatus for agitating the compounding material supplied into the ring 19, at least one rod 6 extending in the diametrical direction inside the ring gear 9 and a plurality of stirrings extending downward from the rod 6 The rotary blade body 3 is configured by providing the rod body 7, and the cylindrical container body 14 of the charge container 19 is located radially outward of the rotary blade body 3, and the rotary blade body 3 is connected to the ring gear. Rotation drive device Mg that rotates through 9 is provided.

In implementation, one or a plurality of rods connected to each other may be used, and unequal pitches may be provided in the circumferential direction. The number of stirring rods may be appropriate, and may be a round bar, a square bar, or a straight bar.
The rotational drive device that rotationally drives the rotary blades may be capable of forward and reverse rotation. Further, a hydraulic motor in which the rotational force and the rotational speed change according to the agitation resistance and there is no sudden rotational speed fluctuation is preferable. However, a so-called geared motor including a reduction gear may be used.
The reciprocating drive device that drives the charge container 19 so as to move back and forth is preferably a hydraulic cylinder, but may be driven by an electric motor.

The effects of the blended raw material supply apparatus of the present invention described above will be listed.
(1) A rotating blade body for agitation mounted inside the container body part is formed by a rod and a plurality of agitation rods attached to the rod below, and the agitation rotation direction is reversed in the normal and reverse directions so as to agitate. If comprised, unlike the stirring of the one-way rotation by the conventional plate-shaped object, a mixing | blending raw material will be mixed evenly and it can mix uniformly as if it stirs sushi western rice with a finger.
(2) Since the rotating blade body is driven by the ring gear, the rigidity of the entire stirring device is improved, and there is an advantage that the blended raw materials can be uniformly mixed without any unevenness by being able to stir the blended raw materials without rotation and looseness. .
(3) Since the blended raw materials are uniformly mixed, there is no error in the brick sizing thickness, and there is no need to adjust the pressure applied to the blended raw materials, and the conventional problem that the molding bulk density fluctuates. There is a lost advantage.
(4) Since the rotating blade body can be agitated by alternately inverting and rotating the rotating blade body, there is an advantage that more uniform mixing can be achieved.
(5) Since stirring is performed with a plurality of stirring bars, the blended raw materials are kneaded with each other between the bars, and there is an advantage that the effect of stirring is increased.
(6) Since the rotation drive device is provided outside the charge container, there is an advantage that the rotation drive device can be maintained without removing the charge container.

Hereinafter, an embodiment of a rotary compound raw material supply apparatus of the present invention will be described with reference to the drawings.
FIG. 1 is an overall side cross-sectional view of the rotary type compound raw material supply apparatus of the present invention, and FIG. 2 is a view showing a lower surface cut along the line AA in order to display the rotary blade body of FIG.

  1 and 2, the compounding raw material supply apparatus denoted by reference numeral 1 as a whole includes a container-like charge container 19, a rotating blade body 3 for stirring that is rotatably mounted in the charge container 19, and a rotating blade body. When 3 is rotationally driven, a drive device Mg such as a hydraulic motor and a charge table 13 are provided.

The charge container 19 is provided with a morning glory hopper 21 for receiving the blended raw material at the upper part, and an opening at the lower part of the hopper 21 is connected to a horizontal top part 22 a of a container body part 22 having a deformed hexagonal cylindrical shape. A cylindrical container body 14 having a smaller diameter than the container body part 22 is formed below the container body part 22, and the container body part 22 and the cylindrical container body 14 are connected by a horizontal plate 23 parallel to the top part 22a. Yes.
Since the driving device Mg is located outside the container body portion 22, it is not easily contaminated by the blended raw materials.

  The lower end of the cylindrical container body 14 is opened, and is configured to slide horizontally on the upper surface of the charge table 13 described later.

  The rotary blade body 3 has a ring gear 9 attached to the outer peripheral portion thereof, and an annular body 8 attached to the inner peripheral portion of the ring gear 9. In the illustrated example, four rods 6 extending in the diameter direction of the annular body 8 are the central portion. Are connected to each other via the annular ring portion 6a. The rod 6 may be provided in the diameter direction of the ring body 8. However, the ring portion 6a is not necessarily provided.

FIG. 3 shows a guide device for rotational movement by the ring gear 9. The ring body 8 constituting the guide device is formed in a ring shape having an open bottom, and the upper portion of the container body 14 is fitted in the ring-shaped groove. And configured to guide the rotation of the ring gear.
The ring gear 9 is attached to the outer wall 8b of the ring body 8, and is configured to mesh with a pinion gear 2 to be described later, which is mounted on the hydraulic motor Mg of the rotary drive device.

The lower end surface 8c of the outer wall 8b is slidably supported on the upper surfaces of the shoulder portions 14b of the four brackets 14a provided outside the cylindrical container body 14 in the drawing.
Further, the outer surface of the outer wall 8 b is configured to contact the vertical surfaces 14 c of the three brackets 14 a separated from the pinion gear 2 to support the horizontal force from the pinion gear 2.

  In each of the rods 6, three stirring rods 7 having the same length are attached in the vertical direction below. The stirring bar 7 may be a round bar, a square bar, or a bent one that is not straight.

Further, the hydraulic motor Mg is attached to another bracket 14d provided outside the cylindrical container body 14, and the pinion gear 2 that meshes with the ring gear 9 is attached to the upper end portion of the hydraulic motor Mg as described above. ing. A pipe (not shown) for supplying hydraulic pressure to the hydraulic motor Mg is connected to an external hydraulic source.
As shown in FIG. 3, the hydraulic motor Mg and the pinion gear 2 are provided outside the container body 22 of the charge container 19 and are configured to be easily maintained.

  The hydraulic cylinder Cy is fixed to the charge table 13 on the hopper 26 side, and the piston Ps is fixed to the horizontal plate 23. The piston Ps causes the charge container 19 to slide from the hopper 29 to the metal frame 16, and at the top of the metal frame 16, the charge container 19 is vibrated little by little back and forth to make the cylindrical container body 14 uniform. The blended raw material G is screened into the cavity S.

  As described above, the rotary blade body 3 for mixing and mixing the blended raw material G in the cylindrical container body 14 is obtained from the torsional rigidity of the motor Mg shaft and the horizontal torsional rigidity of the pinion gear 2 and the ring gear 9. Since it is swung by the extremely high torsional rigidity of the transmission system, it becomes a configuration that, in combination with the rotational inertia moment of the entire rotating blade body 3, does not cause drive system vibration due to uneven stirring resistance, and that smooth stirring is possible. ing.

The operation of the rotary-type blended raw material supply apparatus having the above-described configuration will be described with reference to the above drawings.
First, in FIG. 1, the hopper 21 of the charge container 19 of the blended raw material supply apparatus 1 located on the right side in the figure has an appropriate amount of the blended raw material G that is stirred to some extent in the hopper 26 disposed on the upper right. Supplied by conveyor 39.

  The blended raw material G from the conveyor 39 falls from the hopper 21 to the container body 14 and is stored. The rotating blade body 3 at this time is in a rotating state, but may be in a stopped state. At this time, the depth H of the blended raw material G is not necessarily flat.

Next, the rotating blade body 3 rotates at a predetermined rotation speed at predetermined forward and reverse intervals, and the mixing raw material G is stirred by a large number of stirring rods 7. Since the mixing raw material G in the container body 14 is in a non-uniform state, the agitation resistance has non-uniform variations and tends to be awkward to rotate, but the large rotational force by the ring gear 9 and the slip of the hydraulic motor Mg Stirring is performed with a smooth rotational speed fluctuation like a so-called fluid clutch.
Further, since the plurality of stirring rods 7 stir the blended raw material, the blended raw materials between the stirring rods 7 are finely kneaded.

  The blended raw material G that is uniformly stirred in this manner has a uniform depth H, and the upper surface of the charge table 13 is leveled by the piston Ps of the cylinder Cy up to the position of the blended raw material supply device 1 in FIG. The container body 14 moves to the upper part of the metal frame 16 by sliding.

  Then, the piston Ps moves back and forth in small increments so that the uniform blended raw material G in the container body 14 is uniformly filled into the cavity S formed by the plunger 18 and the metal frame 16. The charge container 19 is pulled by the piston Ps and moves from the metal frame 16 toward the hopper 26.

  Next, the upper plunger falls and the mixed raw material G in the cavity S is compressed together with the plunger 18 to form a brick with a fixed size. The compression may be performed at a predetermined maximum load for uniform mixing of raw materials, and it is not necessary to adjust the pressure to maintain a fixed size.

In brick raw angle e.g. bulk specific gravity of 2.8 g / cm ³ by the forming of the brick, and held in ± 0.02 g / cm ^3, the thickness is controlled in a range of ± 0.3 to 0.5 mm Is possible.
