Definitions

  • the invention relates to a material feeder for a refractory brick molding machine, which feeder reciprocates on a table, mixes materials in a charger and feeds materials in the charger to a die of a molding machine.
  • a charger 51 shown in Fig. 5 is adaptable to feed materials into a single cavity (die) 16, which cavity is placed lengthwise in a horizontal direction as shown in Fig. 5.
  • a charger 52 shown in Fig. 6 is adaptable to feed materials into a plurality of cavities 17, which cavities are arranged side by side.
  • each of the charger 51 and the charger 52 two pairs of mixing blades 19, 22, which blades rotate around the vertical shafts in an opposite direction to each other, are arranged in an oblong circle-shaped charger case 18 or 21.
  • the mixing blades 19, 19 are aligned in a reciprocating (forward and backward) direction X, and driven by a single drive unit 31 which unit is positioned in an upper area.
  • the mixing blades 22, 22 are aligned in a direction being rectangular to the reciprocating direction X, and the drive units 32, 32 are positioned in upper areas respectively.
  • a direction of arrangements of cavities in a die is different from a reciprocating direction of the charger (51, 52).
  • a center lines of lengthwise shaped bricks to be molded are rectangular to a traveling direction of chargers (51, 52).
  • a molding machine includes chargers, traveling directions of which correspond to the cavities arrangement direction and the center lines of lengthwise shaped bricks, respectively.
  • a charger 53 capable of meeting any arrangement of cavities in a vertical direction and/or horizontal direction has been developed.
  • a charger case 23 capable of covering each of the cavities 16 and 17 placed in vertical and lateral directions, mixing blades 24 are provided and driven by a reduction motor 10 via a drive unit 33 including a bevel gear 33a, which gear 33a is located above the mixing blades 24.
  • the charger case 23 is moved forward and backward in the direction X on the table 3 by an actuator 11.
  • any of the aforementioned chargers 51 to 53 in the above-mentioned prior art have a significant effectiveness.
  • a position for charging the materials is limited due to the drive unit (31, 32, 33) located in the upper portion of the charger case.
  • the mixing blades (19, 21, 24) are set, a charging state of materials cannot be visually checked sufficiently, due to the casing of the drive unit.
  • a way of adjusting the feeding of materials is merely employed by detecting the thickness of the materials in the charger using a supersonic type level gauge, or by detecting the drive torque of the mixing blades.
  • a material feeder for a refractory brick molding machine which reciprocates on a table and mixes materials in a charger in order to feed the materials into a die in the molding machine
  • said charger comprises a charger body reciprocating on the table, a cylindrical charger case being provided so as to be removable from and be able to rotate in an opening formed in the charger body, a rotation means for rotating the charger case, and a plurality of mixing blades being suspended in the charger case.
  • said charger case is held in the charger body so as to be removable from and be able to rotate via a bearing by a rotation base, which base is secured on the upper portion in an outer surface of said charger case.
  • each of said mixing blades is suspended from a support bar, both ends of which are secured on the inner surface of said charger case so as to bridge said charger case.
  • said mixing blade is provided with a blade portion at one end of a shaft portion thereof, which end is opposite from the other end being secured on the inner face of said charger case.
  • the cylindrical charger case placed in the opening is rotated, whereby the material is mixed by the mixing blades secured on the inner face of the charger case.
  • the charger is reciprocated forward and backward on the table to discharge the materials into a die.
  • the charger case is held in the charger body through a bearing by the rotation base which is fixed on the upper portion of the outer surface of the charger case, and additionally, the rotation base is rotated by a drive unit which is placed in the outside so as not to position any drive unit in the upper portion of the charger, resulting in a wider area of the charging portion and facilities of visually checking the mixing conditions and adjusting the mixing blades. Furthermore, the charger case is provided detachably, so that the inside thereof and the mixing blades are smoothly cleaned and also can be removed and replaced.
  • a cavity 16 for molding a brick is formed on a lower plunger 2 attached to a metallic frame 1 in a refractory brick molding machine.
  • a table 3 is provided for transfer of materials M into the cavity 16 and a charger indicated in its entirety by reference numeral 50 is formed on the table 3.
  • a charger body 4 constructing a fragmentary portion of the charger 50 is provided to be reciprocated to and fro in a direction of arrow X by an actuator 11 which is secured on the table 3.
  • a circle-shaped opening 4a which receives materials M charged from a conveyor 7 located above the charger body is formed so that the lower end thereof is opened onto the face of the table 3, and leakage of materials M is prevented by a seal 27 formed around the peripheral contact face.
  • a cylindrical charger case 6 is provided to be rotated by means of a bearing 28 by a rotation base 5 secured on the external circumferential face thereof, and detachably (removably) held in the charger body 4.
  • a retention space for materials M. illustrated with reference symbol S which covers the cavity 16 placed in a longitudinal shape as shown in Fig. 2 and a plurality of cavities 17 arranged side by side perpendicularly to the reciprocating direction X as shown in Fig. 3, is formed.
  • support bars 14 and 15 each of which ends are secured on the inner face of the case 6 are vertically arranged to be perpendicular to each other, and respectively suspend a plurality of mixing blades 12 and 13.
  • a pulley provided with a tooth form 5a is formed, and additionally a tooth belt 8 is wound on between the pulley and a drive pulley 9 of the reduction motor 10 fixed to the charger body 4.
  • the charger body 4 is reciprocated to and fro on the table 3 by the actuator 11, while the charger case 6 in the charger body 4 is rotated by the reduction motor 10 via the tooth belt 8.
  • the materials M charged from the opening 4a of the charger body 4 by the conveyor 7 are mixed in the space, which is formed by the periphery of the charger case 6 and the top face of the table 3, by the mixing blades 12 and 13 which are rotated with the rotation of the charger case 6, and then advanced on the table 3 to be transferred into the cavity 16.
  • the depth of the materials M in the case 6 is adjusted to achieve an optimum depth by a supersonic type level gauge (not shown).
  • the drive unit since the drive unit is not placed above the charger case 6, an area of a material charging portion is larger, and the mixing conditions can be visually checked, and moreover, the mixing blades 12 and 13 are readily regulated. Additionally, the charger case 6 is detachable with the mixing blades 12 and 13, so that the inside of the case 6 and the mixing blades 12 and 13 are easily cleaned.
  • a lower portion of a charger case 6A is shorter in length.
  • a plurality of mixing blades 12A and 13A are each directly attached on the inner face of the case 6A at one end of a shaft portion thereof, and a blade portion is formed at the other end thereof.
  • an area of the case 6A for charging the materials is larger and the handling of the detaching/attaching operation or the like is effortless due to the shorter height of the case.
  • the present invention is constructed as described hereinbefore and the following effects are obtained:
