Has been. The bottom surface of the container body 16 is formed in a substantially semicircular cross section in the left-right direction, and an opening 19 is formed on the lower side of the container body 16, that is, on the lower front surface.

  A raw material discharge port body 21 having a raw material discharge port 20 for discharging the raw material in the raw material container 12 is attached to the mouth portion 19 of the container body 16, and the raw material in the raw material container 12 is discharged to the bottom portion in the raw material container 12. A screw 22 as a raw material delivery body to be fed into the outlet 20 is arranged with the axial direction directed in the front-rear direction of the raw material container 12.

  The screw 22 has a rotation shaft 24 at the center, and a spiral screw portion 25 for transferring the raw material is formed around the rotation shaft 24. The front end of the rotation shaft 24 is rotatably supported by the raw material discharge port body 21, and the rear end of the rotation shaft 24 is rotatably supported through the rear surface of the container body 16.

  At the rear end of the rotating shaft 24 of the screw 22 protruding from the rear surface of the raw material container 12, a coupling joint 28 is attached that is detachably connected to a drive shaft 27 disposed in the raw material container mounting portion 13. The drive shaft 27 is disposed so as to be substantially coaxial with the screw 22, and a pin 29 to which the coupling joint 28 is detachably connected is penetrated and fixed in a direction crossing the axial direction of the drive shaft 27. Then, by driving a motor 31 connected to the drive shaft 27 via the speed reducer 30, the screw 22 is rotated in accordance with the direction in which the raw material is fed into the raw material discharge port 20.

  The raw material discharge port body 21 has a cylindrical raw material discharge port portion 33 joined to the periphery of the mouth portion 19 of the container body 16, and the raw material discharge port 20 is formed inside the raw material discharge port portion 33. The material receiving opening 20a of the material discharging port 20 communicating with the mouth 19 of the container main body 16 is formed on the base end side of the material discharging port 33, and the material discharging of the material discharging port 20 is formed on the tip side of the material discharging port 33. An opening 20b is formed.

  On both sides of the raw material discharge port portion 33, locking claws 35 are provided so as to be inserted and locked in mounting holes 34 provided outside the front surface of the container main body 16. At an intermediate position with respect to the distal end side, an engagement piece 36 that engages with the raw material container mounting portion 13 protrudes.

  The end surface of the material discharge port 33 where the material discharge port 20 opens (the end surface on the side of the material discharge opening 20b) is cut in an upwardly inclined shape so that the lower side protrudes from the material container 12 from the upper side. Is formed.

  On the lower side of the end of the raw material discharge port 33 where the raw material discharge port 20 opens (the end on the raw material discharge opening 20b side), a rising inclined portion 37 that rises and slopes toward the opening of the raw material discharge port 20 is formed. In addition, a protruding portion 38 is formed so as to protrude downward from the upper portion of the rising inclined portion 37. The protruding portion 38 is inclined along the inclination of the end surface of the raw material discharge port portion 33 and protrudes obliquely downward so that the lower side of the protruding portion 38 is separated from the raw material container 12. Furthermore, the protruding portion 38 is formed in a semicircular shape along the outer shape of the raw material discharge port portion 33.

A rib 39 that prevents the material from falling from the raw material discharge port 20 is formed to protrude horizontally.

  A raw material chute 41 is used to guide the raw material discharged from the raw material discharge port 20 of the raw material discharge port 33 to a mixing ball or the like for mixing with hot water or cold water. The raw material chute 41 is formed in a container shape having an open bottom, and a fitting hole 42 larger than the raw material discharge port portion 33 is formed so as to be fitted outside the raw material discharge port portion 33.

  Next, the operation of the raw material supply apparatus 11 will be described.

  A powdery raw material is accommodated in the raw material container 12.

  When the raw material is supplied, the motor 31 is driven to rotate for a predetermined time or a predetermined amount. By driving the motor 31, the screw 22 rotates, and the raw material guided to the bottom of the raw material container 12 by the rotation of the screw 22 is transferred from the mouth portion 19 of the raw material container 12 to the raw material discharge port 20 of the raw material discharge port body 21. Send it in.

  By feeding the raw material into the raw material discharge port 20, the raw material in the raw material discharge port 20 is pushed out toward the raw material discharge opening 20b, and the raw material sequentially falls from the opening edge of the raw material discharge port 20b of the raw material discharge port 20, and a predetermined amount of Discharge the raw material.

  The raw material discharged from the raw material discharge port 20 travels along the surface side of the protruding portion 38 and falls into the raw material chute 41 from the tip of the protruding portion 38.

  In addition, the raw material is apt to be electrostatically rubbed due to the discharging operation by rotation of the screw 22 or the like. When the electrostatically charged material is discharged from the material discharge port 20, the electrostatically charged material travels along the surface side of the protruding portion 38 and falls into the raw material chute 41 from the tip of the protruding portion 38. That is, the raw material that has traveled along the surface side of the protruding portion 38 and reached the tip of the protruding portion 38 does not go up to the lower surface of the raw material discharge port portion 33 ascending the back side of the protruding portion 38, It falls into the raw material chute 41 from the tip. Therefore, the material supply device 11 is installed without being scattered outside the raw material chute 41 through the gap between the raw material discharge port 33 and the fitting hole 42 of the raw material chute 41 through the lower surface of the raw material discharge port 33. It is possible to prevent the vicinity of the raw material container mounting part 13 such as a tea machine being used from being contaminated with raw materials.

  In addition, since the protruding portion 38 protrudes downward from the upper portion of the rising inclined portion 37 provided so as to be inclined upward toward the raw material discharge port 20 at the lower edge portion of the raw material discharge port portion 33, static electricity is discharged. It is possible to more reliably prevent the charged material from being transmitted to the lower surface side of the material discharge port 33.

  Furthermore, since the lower side of the protrusion 38 protrudes obliquely downward so as to be separated from the raw material container 12, it is more reliably prevented that the charged raw material is transmitted to the lower surface side of the raw material discharge port 33. it can.

  In addition, the rib 39 protruding from the material discharge port 20 holds the material in the material discharge port 20 and prevents the material from being collected all at once and falling out of the material discharge port 20, thereby stabilizing the material discharge rate. It is possible to stabilize the strength of the beverage.

  Note that the shape, angle, and the like of the protruding portion 38 may be set as appropriate according to each use condition. For example, by causing the protruding portion 38 to protrude longer than the outer shape of the material discharge port portion 33, it is possible to more reliably prevent the charged material from being transmitted to the lower surface side of the material discharge port portion 33.

  Further, the raw material discharge port 33 is not limited to a separate body, and a part or the whole of the raw material container 12 may be provided integrally.
