ない。(e) Operation When the motor rotates in the forward direction, the rotation of the drive shaft is transmitted by the one-way clutch so that the sales door opens. As a result, the beverage cup protrudes from the cup outlet, and the customer can take out the cup by simply grasping it. Then, when the sales door opens, the spring member is loaded with a spring force in the direction of closing the sales door, and when the drive shaft rotates in the opposite direction and the sales door closes, this spring force acts to return the sales door. On the other hand, when the vending door closes, the door open switch detects the rotational position of the drive shaft and stops the motor. 6 If your hand is caught when the vending door closes, the vending door will rotate and the door open switch will stop. Stop at . At this time, the torsion spring is twisted and this torsional moment is only applied to the hand, and the rotational torque of the motor is safe because the one-way clutch prevents the reverse rotational force of the drive shaft from being transmitted to the sales door. . Therefore, a situation as serious as injuring a hand or the like will not occur.

される。■Basic operation during normal operation■ Operation to open the sales door 6 The power of the motor 7 is transmitted via the deceleration transmission mechanism 8, and the drive shaft 9 rotates counterclockwise. Then, power is transmitted to the one-way clutch 12 by the spring pin 10, and the same-direction clutch 12 also rotates counterclockwise. In this case, the triangular protrusions 14 and 16 on the one-way clutch 12 side and the sales door 6 side are firmly attached to the right-angled surface 13a, partly because the one-way clutch 12 is pushed upward by the coil spring 18. Since 17a mesh with each other, power is transmitted and the vending door 6 rotates counterclockwise. At this time, the torsion spring 20 is tightened and a clockwise spring force is accumulated.

んで取り出せば良い。When the sales door 6 rotates to the state shown by the dashed line in FIG. 3, the motor 7 stops and the sales door 6 also stops in response to a detection signal from the door open detection sensor 21. At this time, the take-out port 4 of the cover member 5 and the opening 19 of the sales door 6 overlap and become open, so that the cup 3 placed on the moving stage 30 is moved from the position shown by the two-dot chain line as shown in FIG. It protrudes as shown in the solid line position. The customer only has to grab the cup 3 from the outlet 4 and take it out.
■販売扉６を閉じる動作 モータ７が逆転して、駆動軸９が時計方向に回転する。■Operation of closing the sales door 6 The motor 7 is reversely rotated, and the drive shaft 9 is rotated clockwise.

販売扉６も時計方向に回転する。Further, as described above, the one-way clutch 12 also rotates clockwise. Since the torsion spring 20 presses the right-angled surfaces 17a, 17a of the projections on the sales door 6 side against the right-angled surfaces 13a, 13a of the projections of the one-way clutch 12,
The sales door 6 also rotates clockwise.
やがて、第３図の実線の状態まで販売扉６が回転すると
、鼻閉検知スイッチ２４による検知信号で。Eventually, when the sales door 6 rotates to the state shown by the solid line in FIG. 3, a detection signal is generated by the nasal congestion detection switch 24.
モータ７は停止、販売扉６も停止する。このとき、取り
出し口４と販売扉６とが重なり、閉じた状態となる。The motor 7 stops and the sales door 6 also stops. At this time, the outlet 4 and the sales door 6 overlap and are in a closed state.
■異常時の動作
■扉開検知センサ２１が故障のとき

が鋤かないので、販売扉６は回転を続ける。■Operation in the event of an abnormality■ When the door open detection sensor 21 is out of order Open the sales door 6 mentioned above (During the operation process, the door open detection sensor 21
is not plowed, so the vending door 6 continues to rotate.
しかし、ストッパー２３によって販売扉６はそれ以上回
転しなくなり、よってこの時点でモータ７はロック状態
となる。そうなると、一定時間通電後、モータ７への通
電を断つように遮断袋Ｎ（図示略）が働く。こうして安
全が図られる。However, the stopper 23 prevents the vending door 6 from rotating any further, and the motor 7 is therefore in a locked state at this point. In this case, a cutoff bag N (not shown) operates to cut off the power to the motor 7 after the power is turned on for a certain period of time. This ensures safety.
この場合、鼻閉検知スイッチ２４は一方向りラッチ１２
０回転により作動しているので扉開検知センサ２１の故
障モードとする。In this case, the nasal congestion detection switch 24 is connected to the one-way latch 12.
Since it is operating at 0 rotation, it is assumed that the door open detection sensor 21 is in failure mode.
■販売扉６を閉じる動作時、手等をはさんだとき販売ｙ
Ｒ６は動かなくなるが、モータ７は回転を続け、やがて
鼻閉検知スイッチ２４による検知信号でモータ７は停止
する。■When closing the sales door 6, if your hand etc. is caught in the sales door 6
Although R6 stops moving, the motor 7 continues to rotate, and eventually the motor 7 is stopped by a detection signal from the nasal congestion detection switch 24.
このとき、捩りバネ２０は捩られて、手にはこの捩りモ
ーメントが加えられるが、モータ７の回転トルクは伝達
されていない。よって、手等がはさまれたとしても大き
なケガとなる危険性は少い。At this time, the torsion spring 20 is twisted and this torsional moment is applied to the hand, but the rotational torque of the motor 7 is not transmitted. Therefore, even if a hand or the like is caught, there is little risk of serious injury.
すなわち、手等で止められている販売扉６側の軸部６ａ
に対して一方向クラッチ１２は時計方向に進み回転して
止まっている状態で、この時の突起同士は位置ずれして

る。In other words, the shaft portion 6a on the sales door 6 side that is stopped by hand etc.
On the other hand, the one-way clutch 12 is in a state where it rotates clockwise and stops, and at this time the protrusions are misaligned and neither the right angle surface nor the tapered surface is in contact with each other.
よって、手等を引き抜けば、捩りバネ２０のモーメント
によって、販売扉６は閉状態まで回転して戻り、以後通
常の動作を続ける。Therefore, when the hand or the like is pulled out, the vending door 6 rotates back to the closed state due to the moment of the torsion spring 20, and thereafter continues its normal operation.

らず、安全装置の作用を十分に発揮できる。■If your hand is caught while closing the sales door 6, and
When the nasal congestion detection switch 24 is out of order, the sales door 6 does not move, but the motor 7 continues to rotate past the stop position. Eventually, the one-way clutch 12 advances clockwise and rotates against the shaft 6a of the sales door 6, which has stopped due to the pinched hand or the like.
When rotated by 80 degrees, the protrusions 16 and 14 come into contact with each other at their tapered surfaces 17b and 14b. one way clutch 1
2 further rotates, and as a result, the one-way clutch 12 is pushed downward against the coil spring 18,
The tapered surfaces 17b and 14b slip and the motor 7
The rotational torque of is not transmitted to the sales H6. Therefore, even if the nasal congestion detection switch 24 malfunctions and the motor 7 overruns, no power is transmitted to the sales door 6.
Even if a situation occurs in which a finger is caught, no serious injury will result, and the safety device will be able to fully demonstrate its effectiveness.

愛する。■When the door open detection switch 24 is out of order, the sales door 6 will not move due to the stopper 26. The subsequent operation is the same as that described above (r=2-3), so it will be omitted.

る。Furthermore, by removing the stopper 26 and pushing down the one-way clutch I2, the engagement between the sales door 6 and the joint portion A of the one-way clutch 12 is released, and the torsion spring 20 is released.
Due to the torsional force, the sales door 6 rotates clockwise and pops out to the rear of the cover member 5. This also has the advantage that the inner surface of the cover member 5 and the upper surface of the sales door 6 can be cleaned.

ことは避けられる。(G) Effects of the Invention According to the present invention, when the vending door that opens and closes the cup outlet opens, power is transmitted by a one-way clutch attached to the drive shaft to which the driving force of the motor is transmitted. Since the sales door is configured so that it opens and closes using a spring that is twisted when it opens and exerts a torsional moment in the closing direction, even if a hand or finger is caught when the sales door is closed, only the spring force is applied. It is safe because the rotational torque of the motor is not transmitted to the sales door. Then, when only the drive shaft rotates and reaches the rotational position, the nasal congestion detection switch is activated to stop the motor, thereby ensuring that the operation is stopped. Also, this nasal congestion detection switch malfunctions,
Even if the drive shaft overruns, the one-way clutch will slip and no power will be transmitted to the sales door, so it is possible to avoid getting your fingers caught in a serious situation.
