Description
本発明は、カップ式自動販売機や飲料ディスペンサに備えられ、駆動手段に連結させたキャニスタオーガを回転させ、原料貯蔵部に貯蔵している粉末原料を供給口から搬出する粉末原料供給装置に関する。 The present invention relates to a powder raw material supply apparatus that is provided in a cup-type vending machine or a beverage dispenser, rotates a canister auger connected to a driving means, and carries out a powder raw material stored in a raw material storage unit from a supply port.
たとえば、この種の粉末原料供給装置として図９に示すものが知られている。この粉末原料供給装置６０は、砂糖やクリームなどの粉末原料を貯蔵する貯蔵容器６１と、軸６２で回動自在に貯蔵容器６１の上端開口を覆うカバー６３と、貯蔵容器６１が固定手段（図示せず）で着脱自在に取り付けられる搬出部６４と、搬出部６４の前面下端部（図中、左下端）に前方に突出するように形成された円筒形状の供給口６５とが設けられている。 For example, such a powder raw material supply apparatus shown in FIG. 9 is known. The powder raw material supply device 60 includes a storage container 61 that stores powder raw materials such as sugar and cream, a cover 63 that covers the upper end opening of the storage container 61 so as to be rotatable about a shaft 62, and a storage container 61 that is fixed by a fixing means (FIG. A carry-out portion 64 that is detachably attached to the carry-out portion 64 and a cylindrical supply port 65 that is formed so as to protrude forward is provided at the lower front end portion of the carry-out portion 64 (the lower left end in the figure). .
また、搬出部６４の底部には、粉末原料を供給口６５から搬出するための回転自在のキャニスタオーガ７０が配設されている。キャニスタオーガ７０は、前後方向（図中、左右方向）に水平に延びる金属軸７１の外周面上に熱可塑性樹脂を射出成型して螺旋羽根７２ａを一体に成型加工した回転軸７２で形成されている。金属軸７１の一端（図中、右端）には螺旋羽根７２ａの螺旋方向と逆方向のねじが加工されたおねじ７１ａが設けられ、回転爪７３がねじ止めされている。このキャニスタオーガ７０を回転させるための駆動モータ３０の駆動軸には駆動ピン３１が取り付けられ、駆動モータ３０の回転が駆動ピン３１から回転爪７３を介してキャニスタオーガ７０に伝達される。 In addition, a rotatable canister auger 70 for unloading the powder raw material from the supply port 65 is disposed at the bottom of the unloading section 64. The canister auger 70 is formed of a rotating shaft 72 in which a thermoplastic resin is injection-molded on the outer peripheral surface of a metal shaft 71 that extends horizontally in the front-rear direction (the left-right direction in the figure), and a spiral blade 72a is integrally molded. Yes. One end (right end in the figure) of the metal shaft 71 is provided with a male screw 71a in which a screw in a direction opposite to the spiral direction of the spiral blade 72a is processed, and a rotating claw 73 is screwed. A drive pin 31 is attached to the drive shaft of the drive motor 30 for rotating the canister auger 70, and the rotation of the drive motor 30 is transmitted from the drive pin 31 to the canister auger 70 via the rotation claw 73.
また、キャニスタオーガ７０の上方には、回転軸７２に形成された螺旋羽根７２ａに噛み合わせて設けられた第１歯車６６と、第１歯車６６に噛み合わせた第２歯車６７とが回転自在に設けられ、キャニスタオーガ７０の回転に連動して第１歯車６６と第２歯車６７が回転（図中、矢印方向）し、粉末原料が湿気を含み、粉末原料供給装置６０内で固まり、キャニスタオーガ７０の螺旋羽根７２ａ間への粉末原料の取り込みが停滞する現象を防止している。 Further, above the canister auger 70, a first gear 66 provided in mesh with a spiral blade 72a formed on the rotary shaft 72 and a second gear 67 meshed with the first gear 66 are rotatable. The first gear 66 and the second gear 67 are rotated (in the direction of the arrow in the figure) in conjunction with the rotation of the canister auger 70, the powder raw material contains moisture, and is solidified in the powder raw material supply device 60. This prevents the stagnation of the powder raw material taken in between the 70 spiral blades 72a.
この粉末原料供給装置６０を備えたカップ式自動販売機では、利用者によって飲料販売ボタンが押されて飲料が選択されると、飲料販売信号に基づいて粉末原料搬出信号が出力され、駆動モータ３０が回転駆動されると駆動ピン３１から回転爪７３を介してキャニスタオーガ７０が所定数回転（図中、左側から見て時計回り方向）する。キャニスタオーガ７０が所定数回転すると、螺旋羽根７２ａ間に充足されている粉末原料が図中、左方向へ送り出され、供給口６５から所定量の粉末原料が搬出される。このようにして搬出された粉末原料は、湯タンク（図示せず）から供給された湯と攪拌混合され、調製されたカップ飲料として利用者に引き渡される（例えば、特許文献１参照）。 In the cup type vending machine provided with the powder raw material supply device 60, when the beverage is pressed by the user and the beverage is selected, a powder raw material carry-out signal is output based on the beverage sales signal, and the drive motor 30 Is driven to rotate, the canister auger 70 rotates a predetermined number of times from the drive pin 31 through the rotating claw 73 (clockwise as viewed from the left side in the figure). When the canister auger 70 rotates a predetermined number of times, the powder raw material filled between the spiral blades 72a is sent leftward in the figure, and a predetermined amount of the powder raw material is carried out from the supply port 65. The powder raw material carried out in this way is stirred and mixed with hot water supplied from a hot water tank (not shown) and delivered to the user as a prepared cup beverage (for example, see Patent Document 1).
キャニスタオーガ７０が回転すると、貯蔵容器６１内の粉末原料が螺旋羽根７２ａ間に取り込まれ、螺旋羽根７２ａの回転による送り出し作用で供給口６５側に送り出され、供給口６５から搬出される。 When the canister auger 70 rotates, the powder raw material in the storage container 61 is taken in between the spiral blades 72 a, sent to the supply port 65 side by the feed action by the rotation of the spiral blade 72 a, and unloaded from the supply port 65.
しかしながら、キャニスタオーガ７０が回転すると、専らキャニスタオーガ７０の駆動モータ３０側で螺旋羽根７２ａ間に粉末原料が取り込まれ、取り込まれた粉末原料が供給口６５側に送り出されるため、供給口６５側には螺旋羽根７２ａ間に粉末原料が充足された状態になって送られてくる。そのため、供給口６５側ではキャニスタオーガ７０の螺旋羽根７２ａ間に新たに粉末原料が取り込まれることがなくなる。 However, when the canister auger 70 rotates, the powder raw material is taken in between the spiral blades 72a exclusively on the drive motor 30 side of the canister auger 70, and the taken-in powder raw material is sent out to the supply port 65 side. Is sent in a state where the powder raw material is filled between the spiral blades 72a. Therefore, no new powder raw material is taken in between the spiral blades 72a of the canister auger 70 on the supply port 65 side.
このように、キャニスタオーガ７０が回転すると、キャニスタオーガ７０の駆動モータ３０側の螺旋羽根７２ａ間には粉末原料が取り込まれるが、取り込まれた粉末原料が螺旋羽根７２ａで送り出されて供給口６５側では充足した状態になっているため、供給口６５側では螺旋羽根７２ａ間に粉末原料が取り込まれなくなる。この結果、キャニスタオーガ７０の駆動モータ３０側と供給口６５側では、貯蔵容器６１内に貯蔵されている粉末原料の螺旋羽根７２ａ間に取り込まれる量に差が発生する。 Thus, when the canister auger 70 rotates, the powder raw material is taken in between the spiral blades 72a on the drive motor 30 side of the canister auger 70, but the taken-in powder raw material is sent out by the spiral blades 72a to the supply port 65 side. Then, since the state is satisfied, the powder raw material is not taken in between the spiral blades 72a on the supply port 65 side. As a result, on the drive motor 30 side and the supply port 65 side of the canister auger 70, a difference occurs in the amount of powder raw material stored in the storage container 61 between the spiral blades 72a.
そして、利用者によるカップ式自動販売機での飲料販売が繰り返し行われ、キャニスタオーガ７０の回転により粉末原料が大量に搬出されると、キャニスタオーガ７０の駆動モータ３０側では螺旋羽根７２ａ間に粉末原料が大量に取り込まれるが、供給口６５側では粉末原料が取り込まれないため、貯蔵容器６１内の粉末原料貯蔵高さが供給口６５側では高く、駆動モータ３０側では低くなる、貯蔵容器６１内での粉末原料の貯蔵高さに高低差が生じる。 When beverages are repeatedly sold by the cup type vending machine by the user and a large amount of powder raw material is carried out by the rotation of the canister auger 70, the powder is placed between the spiral blades 72a on the drive motor 30 side of the canister auger 70. A large amount of raw material is taken in, but since the powder raw material is not taken in on the supply port 65 side, the storage height of the powder raw material in the storage vessel 61 is high on the supply port 65 side and low on the drive motor 30 side. A difference in height occurs in the storage height of the powder raw material.
カップ式自動販売機に備えられている粉末原料供給装置６０は、貯蔵容器６１が半透明の熱可塑性樹脂で形成されており、自販機オペレータは、貯蔵容器６１の供給口６５側から粉末原料の残量を確認し、残量が少なくなっている場合には粉末原料を補充するようにしている。 In the powder raw material supply device 60 provided in the cup type vending machine, the storage container 61 is formed of a translucent thermoplastic resin, and the vending machine operator can leave the powder raw material from the supply port 65 side of the storage container 61. The amount is checked, and when the remaining amount is low, the powder raw material is replenished.
しかしながら、貯蔵容器６１内に貯蔵されている粉末原料の貯蔵高さが駆動モータ３０側では低くなっていても、供給口６５側では高い状態になっていると、粉末原料の残量を見誤ってしまう可能性があった。 However, if the storage height of the powder raw material stored in the storage container 61 is low on the drive motor 30 side but is high on the supply port 65 side, the residual amount of the powder raw material is mistaken. There was a possibility.
本発明は、以上のような課題を解決するためになされたものであり、原料貯蔵部に貯蔵されている粉末原料の貯蔵高さを均等に下降させて残量の確認を見誤ることがない粉末原料供給装置を安価に提供することを目的とする。 The present invention has been made to solve the above-described problems, and does not mistakenly confirm the remaining amount by uniformly lowering the storage height of the powder raw material stored in the raw material storage unit. An object is to provide a powder raw material supply apparatus at a low cost.

キャニスタオーガ２０の上方には螺旋羽根２１ｂに噛み合うようにして第１歯車１６が回転自在に設けられ、その上方前側には第２歯車１７が第１歯車１６と噛み合って回転自在に設けられている。貯蔵容器１１、搬出部１４内では、キャニスタオーガ２０が回転して粉末原料搬出動作が行われると粉末原料が下方に移動する過程で粉末原料に空洞が生じる現象や、粉末原料が湿気を含み固まる現象が発生することがあるが、キャニスタオーガ２０の回転に連動して第１歯車１６、第２歯車１７が回転すると、粉末原料がかき混ぜられて下方に安定して移動するので、キャニスタオーガ２０の螺旋羽根２１ｂ間への粉末原料の取り込みが停滞して搬出ができなくなることを防止している。 A first gear 16 is rotatably provided above the canister auger 20 so as to mesh with the spiral blade 21b, and a second gear 17 is meshed with the first gear 16 and rotatably provided on the upper front side thereof. . In the storage container 11 and the carry-out unit 14, when the canister auger 20 rotates and the powder raw material carry-out operation is performed, the powder raw material moves in the downward direction, and the powder raw material contains moisture and solidifies. Although the phenomenon may occur, when the first gear 16 and the second gear 17 rotate in conjunction with the rotation of the canister auger 20, the powder raw material is agitated and stably moves downward. It prevents that the powder raw material intake between the spiral blades 21b is stagnant and cannot be carried out.
このように、キャニスタオーガ２０の駆動モータ３０側から供給口１５側に先細りとなる中空テーパ軸２１ａ外周面上に同一外径の螺旋羽根２１ｂが一体に形成されているので、オーガ軸２１の駆動モータ３０側では螺旋羽根２１ｂの高さが低く、供給口１５側に移るに従い螺旋羽根２１ｂの高さが高くなるので、駆動モータ３０側では螺旋羽根２１ｂ間に取り込まれる粉末原料が少なく、駆動モータ３０側から供給口１５側に亘って均等に取り込まれるようになる。 As described above, the spiral blade 21b having the same outer diameter is integrally formed on the outer peripheral surface of the hollow tapered shaft 21a that is tapered from the drive motor 30 side to the supply port 15 side of the canister auger 20, so that the auger shaft 21 is driven. On the motor 30 side, the height of the spiral blade 21b is low, and the height of the spiral blade 21b increases as it moves to the supply port 15 side. It is uniformly taken in from the 30 side to the supply port 15 side.
そして、搬出部１４の後面下端部（図中、右下端）近傍に配置される駆動モータ３０が回転（図中、左側から見て時計回り方向）駆動されると、駆動モータ３０の駆動軸に取り付けられた駆動ピン３１と連結する連結爪２２ｂを介してキャニスタオーガ２０が回転し、貯蔵容器１１、搬出部１４内に貯蔵されている粉末原料がオーガ軸２１の螺旋羽根２１ｂ間に均等に取り込まれて図中、左方向へと送り出されて供給口１５から搬出されるので、図８に示しているように、粉末原料の貯蔵高さを均等に下降させることが可能となるので、貯蔵容器１１に貯蔵されている粉末原料の残量の確認を見誤ることがなくなる。 When the drive motor 30 disposed in the vicinity of the lower end of the rear surface of the unloading portion 14 (lower right end in the figure) is driven to rotate (clockwise as viewed from the left side in the figure), the drive shaft of the drive motor 30 is driven. The canister auger 20 rotates through the connecting claw 22b connected to the attached drive pin 31, and the powder raw material stored in the storage container 11 and the carry-out portion 14 is evenly taken in between the spiral blades 21b of the auger shaft 21. In FIG. 8, since it is fed leftward and carried out from the supply port 15, the storage height of the powder raw material can be lowered evenly as shown in FIG. 11 to confirm the confirmation of the remaining amount of the powder raw material.
以上のように、本実施形態の粉末原料供給装置１０によれば、駆動モータ３０に連結させたキャニスタオーガ２０を回転させ、貯蔵容器１１、搬出部１４に貯蔵している粉末原料を供給口１５から搬出する粉原料供給装置１０において、キャニスタオーガ２０は、駆動モータ３０側から供給口１５側に先細りとなる中空テーパ軸２１ａ外周面上に一体に形成した同一外径の螺旋羽根２１ｂを有するオーガ軸２１と、該オーガ軸２１のテーパ軸穴２１ｃに挿着されるテーパ状の棒状部材２２ａを有し、駆動モータ３０の回転をオーガ軸２１に伝達する伝達軸２２と、からなることにより、貯蔵容器１１、搬出部１４に貯蔵されている粉末原料が、駆動モータ３０側から供給口１５側に亘ってオーガ軸２１の螺旋羽根２１ｂ間に均等に取り込まれて供給口１５から搬出される。また、金属軸の外周面上に熱可塑性樹脂を射出成型して螺旋羽根を一体に成型加工して回転軸とし、金属軸の一端には螺旋羽根の螺旋方向と逆方向のねじを加工して回転爪をねじ止めしてキャニスタオーガとした高価な部品を使用する必要がなくなる。この結果、原料貯蔵部に貯蔵されている粉末原料の貯蔵高さを均等に下降させて残量の確認を見誤ることがない粉末原料供給装置を安価に提供することができる。 As described above, according to the powder raw material supply apparatus 10 of this embodiment, the canister auger 20 connected to the drive motor 30 is rotated, and the powder raw material stored in the storage container 11 and the carry-out unit 14 is supplied to the supply port 15. In the powder raw material supply apparatus 10 carried out from the can, the canister auger 20 has an auger having the same outer diameter spiral blade 21b integrally formed on the outer peripheral surface of the hollow taper shaft 21a tapering from the drive motor 30 side to the supply port 15 side. By comprising a shaft 21 and a transmission shaft 22 having a tapered rod-like member 22a inserted into the tapered shaft hole 21c of the auger shaft 21 and transmitting the rotation of the drive motor 30 to the auger shaft 21, The powder raw material stored in the storage container 11 and the carry-out part 14 is evenly taken in between the spiral blades 21b of the auger shaft 21 from the drive motor 30 side to the supply port 15 side. It is carried out from the supply port 15. In addition, a thermoplastic resin is injection-molded on the outer peripheral surface of the metal shaft, and the spiral blade is integrally molded to form a rotating shaft. One end of the metal shaft is processed with a screw in the direction opposite to the spiral direction of the spiral blade. There is no need to use expensive parts such as canister augers by screwing the rotating claws. As a result, it is possible to provide a powder raw material supply apparatus that can lower the storage height of the powder raw material stored in the raw material storage unit evenly and does not mistake the confirmation of the remaining amount at low cost.
また、テーパ軸穴２１ｃおよびテーパ状の棒状部材２２ａは６辺形からなり、棒状部材２２ａが設けられている伝達軸２２の他方には駆動モータ３０に設けられた駆動ピン３１と連結する連結爪２２ｂを設け、駆動モータの回転をオーガ軸２１に伝達するようにしたことにより、安価な部品構成で確実に駆動モータ３０の回転をキャニスタオーガ２０に伝達することができる。 The tapered shaft hole 21c and the tapered rod-shaped member 22a are hexagonal, and the other end of the transmission shaft 22 provided with the rod-shaped member 22a is connected to a drive pin 31 provided on the drive motor 30. By providing 22b and transmitting the rotation of the drive motor to the auger shaft 21, the rotation of the drive motor 30 can be reliably transmitted to the canister auger 20 with an inexpensive component configuration.
さらに、オーガ軸２１には突起２１ｄを設け、伝達軸２２には突起２１ｄに嵌合する嵌合部２２ｃを設け、オーガ軸２１に伝達軸２２を固着させるようにしたことにより、安価にキャニスタオーガを構成することができる。 Further, the auger shaft 21 is provided with a projection 21d, the transmission shaft 22 is provided with a fitting portion 22c that fits into the projection 21d, and the transmission shaft 22 is fixed to the auger shaft 21.
