Apparatus for feeding predetermined amounts of pulverised or granular materials

Claim 2

A quantitative feeding apparatus usable for pulverized and/or granular material in which an amount of pulverized and/or granular material to be supplemented to a barrel portion is automatically controlled by measuring a predetermined amount of pulverized or granular material and said predetermined amount of pulverized and/or granular material is then mechanically fed from said barrel portion, wherein a supplementing port through which the pulverized and/or granular material is supplemented is provided on the upper end of the barrel portion, a feeding portion for feeding the pulverized and/or granular material therethrough is provided at an intermediate part of the barrel portion and a discharging portion througn which the pulverized and/or granular material is discharged is provided on the bottom part of the barrel portion and wherein a plurality of cleaning nozzles are provided for the purpose of cleaning said supplementing port, said feeding portion and said discharging portion.

Claim 3

The quantitative feeding apparatus as claimed in claim 1, wherein the pulverized and/or granular material is prepared in the form of a master batch.

Claim 4

The quantitative feeding apparatus as claimed in claim 1, wherein the pulverized and/or granular material is prepared by crushing runners.

Claim 5

The quantitative feeding apparatus as claimed in claim 1, wherein a bridge breaker is arranged in the barrel portion.

Claim 6

The quantitative feeding apparatus as claimed in claim 1, wherein said discharging portion is opened or closed by a cut gate type opening and closing valve.

Claim 7

A master batch type multi-colored automatic feeding apparatus in which an amount of master batch to be supplemented to a barrel portion of a quantitative feeding apparatus is automatically controlled by measuring a predetermined amount of master batch stored in a plurality of master batch storage hoppers and said predetermined amount of master batch is mechanically fed from said barrel portion, wherein said apparatus includes a pneumatic conveyor for conveying the master batch fed therefrom to a molding machine, a separator disposed above said molding machine to separate air from solid material, a mixer including a raw material feeding portion for said molding machine in which the master batch which has fallen down after completion of separation of air from solid material is mixed with a natural resin and selecting and returning means for selecting the kind of master batch discharged from a discharging portion on the bottom part of the quantitative feeding apparatus to be returened to the same kind of hopper among said plural storage hoppers and then returning it therto, wherein a supplementing port through which the master batch is supplemented is provided on the upper end of said barrel portion, a feeding portion for feeding the master batch therethrough is provided at an intermediate part of the barrel portion and a discharging portion through which the master batch is discharged is provided on the bottom part of the barrel portion of the quantitative feeding apparatus and wherein a plurality of cleaning nozzles are provided for the purpose of cleaning said supplementing port, said feeding portion and said discharging portion.

Claim 8

A master batch type multi-colored automatic feeding apparatus in which an amount of master batch to be supplemented to a barrel portion of a quantitative feeding apparatus is automatically controlled by measuring a predetermined amount of master batch stored in a plurality of master batch storage hoppers and said predetermined amount of master batch is mechanically fed from said barrel portion, wherein said apparatus includes a pneumatic conveyor for conveying the master batch fed therefrom to a molding machine, a separator disposed above said molding machine to separate air from solid material, a mixer including a raw material feeding portion for said molding machine in which the master batch which has fallen down after completion of separation of air from solid material is mixed with a natural resin and selecting and returning means for selecting the kind of master batch discharged from a discharging portion on the bottom part of the quantitative feeding apparatus to be returened to the same kind of hopper among said plural storage hoppers and then returning it therto, wherein a supplementing port through which the master batch is supplemented is provided on the upper end of said barrel portion, a feeding portion for feeding the master batch therethrough is provided at an intermediate part of the barrel portion and a discharging portion through which the master batch is discharged is provided on the bottom part of the barrel portion of the quantitative feeding apparatus and wherein a plurality of cleaning nozzles are provided for the purpose of cleaning said supplementing port, said feeding portion and said discharging portion.

Claim 9

A runner recycling apparatus, wherein a crusher is provided downwardly of a runner introducing chute, a quantitative feeding apparatus having a feeder for quantitatively feeding crushed runner incorporated therein is provided downwardly of said crusher, said quantitative feeding apparatus being formed with a feeding port located in alignment with said feeder, and a discharging port through which said crushed runner is discharged is formed on the bottom part of the quantitative feeding apparatus, wherein a plurality of cleaning nozzles directed toward the interior of the crusher and the interior of the quantitative feeding apparatus are arranged in the vicinity of the runner recycling apparatus and wherein a mixer in which crushed runner and new material are mixed with each other is provided upwardly of a molding machine, said mixer being connected to said feeding port of said quantitative feeding apparatus via a piping.

Claim 10

A runner recycling apparatus, wherein a crusher is provided downwardly of a runner introducing chute, a quantitative feeding apparatus having a feeder for quantitatively feeding crushed runner incorporated therein is provided downwardly of said crusher, said quantitative feeding apparatus being formed with a feeding port located in alignment with said feeder, and a discharging port through which said crushed runner is discharged is formed on the bottom part of the quantitative feeding apparatus, wherein a plurality of cleaning nozzles directed toward the interior of the crusher and the interior of the quantitative feeding apparatus are arranged in the vicinity of the runner recycling apparatus and wherein a mixer in which crushed runner and new material are mixed with each other is provided upwardly of a molding machine, said mixer being connected to said feeding port of said quantitative feeding apparatus via a piping.
