  An embodiment of the invention will be described in detail with reference to the drawings. FIG. 1 is a drawing showing a soy sauce dropping device 10 for nigiri sushi A (shown in FIG. 9) in the present embodiment. The soy sauce dripping device 10 is configured by providing a soy sauce dripping mechanism 13 at the tip of an overhang portion 12 of a base 11 having a substantially U-shaped cross section having an overhang shape.

  As shown in FIG. 1, the central space K having a substantially U-shaped cross section is a space where the nigiri sushi A is located. The lower end flat plate portion H having a substantially U-shaped cross section serves as a mounting portion for the saucer when the soy sauce S is spilled. The soy sauce dripping mechanism 13 includes a soy sauce storage part Y, a vertical cylindrical drop opening part 14 disposed at a predetermined position of the storage part, and a vertically movable piston that is freely fitted in and out of the cylindrical drop opening part 14 The rod valve 15, the valve operating solenoid 16 attached to the upper end portion of the piston rod valve 15, and the proximity provided in the overhang portion 12 to sense that the nigiri sushi A is located in the space below the overhang portion 12 And a sensor 18 (sensing unit).

  The soy sauce storage part Y is constituted by a storage case having an inverted substantially L-shaped shape on the upper plate corresponding part of the base 11 having a substantially U-shaped cross section. In addition, a soy sauce inlet 17 and an openable / closable lid 29 are provided on the upper surface of the storage case Y of the soy sauce container Y, and a drip opening is provided at the lower end of the downward projecting portion of the case of the soy sauce container Y. 14 is formed in a cylindrical shape, and a lower portion of a vertically movable piston rod valve 15 penetrating upward through the storage case is loosely fitted in the cylindrical dropping opening 14.

  Therefore, as the piston rod valve 15 is moved up and down, the piston rod valve 15 slides in the cylindrical dropping opening 14 to form a gap with the dropping opening 14 or is closed to close the dropping opening 14. Open and close.

  The upper end of the piston rod valve 15 communicates with the plunger of the solenoid 16 for valve operation (electromagnetic maglet plate 25) disposed on the ceiling of the storage case of the soy sauce storage unit Y, and the plunger of the solenoid 16 for valve operation The nozzle of the dripping opening 14 is opened and closed by the piston rod valve 15 in accordance with the operation (the raising and lowering operation of the electromagnetic maglet plate 25).

  The dropping opening 14 is provided with a dropping adjustment mechanism 19 for adjusting the soy sauce dropping amount. The dropping adjustment mechanism 19 is configured to move the nozzle body 21 up and down by rotating the soy sauce amount adjusting lever 20 in the overhang portion 12 near the dropping opening 14.

  Specifically, as shown in FIG. 2, a screw portion 23 a is formed on the outer peripheral portion of the nozzle holding portion 22 provided at the lower portion of the overhang portion 12, and the nozzle body is screwed into the nozzle holding portion 22. A screw portion 23 b is formed on the inner peripheral surface of 21. And the soy sauce amount adjustment lever 20 protruded to the side from the outer peripheral surface of the nozzle main body 21 is attached.

  Thus, by rotating the soy sauce amount adjusting lever 20 in any direction around the vertical axis, the nozzle body 21 can be moved up and down with respect to the nozzle holding portion 22, and the piston rod valve 15 and the dropping opening portion 14 can be adjusted. The dripping amount of soy sauce S can also be adjusted by the size of the gap.

  That is, as shown in FIG. 4, when the proximity sensor 18 does not detect the nigiri sushi A, the gap between the piston rod valve 15 and the dropping opening 14 is not formed, and the soy sauce S does not drop from the nozzle. As shown in FIG. 5, when the soy sauce amount adjusting lever 20 is rotated counterclockwise in a plan view, the nozzle main body 21 is located above the normal position with respect to the nozzle holding portion 22, and thus the gap is reduced. The dripping amount of soy sauce S per unit time becomes small. On the other hand, as shown in FIG. 6, when the soy sauce amount adjusting lever 20 is rotated in a clockwise direction in a plan view, the nozzle body 21 is positioned below the normal time with respect to the nozzle holding portion 22. The gap increases and the amount of soy sauce S dropped per unit time increases.

  The soy sauce S can be prevented from leaking between the nozzle holding part 22 and the nozzle body 21 by arranging the O-ring 24 on the outer peripheral surfaces of the nozzle body 21 and the nozzle holding part 22. In this way, the user can adjust the amount of soy sauce S used by the dripping adjustment mechanism 19.

  As shown in FIG. 3, a disc-shaped electromagnetic maglet plate 25 is disposed at the upper end of the piston rod valve 15. An annular valve operating solenoid 16 is disposed above the electromagnetic magnetlet plate 25. A coil spring holding portion 26 is provided on the inner peripheral side of the valve operation solenoid 16 and on the upper surface side of the electromagnetic magnet plate, and one end side of the coil spring 27 is fixed to the outer peripheral portion of the coil spring holding portion 26. The other end side of the coil spring 27 is fixed to the inner wall surface of the overhang portion 12. The piston rod valve 15 is pressed against the dropping opening 14 by the coil spring 27 to prevent soy sauce leakage.

  Further, as shown in FIG. 1, a proximity sensor 18 for detecting the proximity of the nigiri sushi A is provided on the bottom surface side of the overhang portion 12. The proximity sensor 18 detects when the center of the material of the nigiri sushi A comes to the dropping opening 14.

  FIG. 7 is a circuit diagram in which the proximity sensor 18, the valve operation solenoid 16 and the battery 28 are connected. As shown in FIG. 7, by connecting these in series, when the proximity sensor 18 detects the nigiri sushi A, the current from the battery 28 is supplied to the valve operation solenoid 16. Thereby, the solenoid 16 for valve operation can be electrically activated. In the present embodiment, the battery 28 provided on the upper part of the overhang portion 12 is used to supply current to the valve operation solenoid 16 in a DC circuit diagram. An AC power source can be used, and an AC / DC converter can be provided in the apparatus to activate the valve operating solenoid 16. Further, by measuring the sensor sensing time of the proximity sensor 18 with a computer, it is possible to know the amount of soy sauce used and the frequency of use in the store, and to know the management of customers in the store, business results, and the like.

  By comprising in this way, the usage method of the soy sauce dripping apparatus 10 of this embodiment is as follows. First, as shown in FIG. 8, by rotating the soy sauce amount adjusting lever 20 in any direction around the vertical axis, the nozzle body 21 can be moved up and down with respect to the nozzle holding portion 22, Adjust the size and set the amount of soy sauce S. Adjustment of the dripping amount of soy sauce S is possible by the method as shown in FIGS.

  Next, as shown in FIG. 9, the nigiri sushi A is picked up with chopsticks and placed close to the bottom of the nozzle with the material placed on the shari, so that the proximity sensor 18 detects the nigiri sushi A for valve operation. A current is supplied from the battery 28 to the solenoid 16. As a result, the valve operation solenoid 16 is turned on, and the electromagnetic maglet plate 25 is pushed upward.

  Then, as shown in FIG. 10, the piston rod valve 15 is pushed upward, and a gap is generated between the tip of the piston rod valve 15 and the dropping opening 14. Through this gap, the soy sauce S in the soy sauce storage part Y provided in the overhang part 12 flows into the dropping opening 14, and a predetermined amount of soy sauce S can be dropped from the tip of the dropping opening 14. Moreover, as shown in FIG. 11, the dripping amount of soy sauce S can be adjusted by the sensing time of the proximity sensor 18. Thus, since the soy sauce S is dripped when the nigiri sushi A is sensed by the sensing part, the remaining use of the soy sauce S as in the conventional case can be reduced.

  After the predetermined amount of soy sauce S is applied, the proximity sensor 18 is turned off and the valve operation solenoid 16 is also turned off by moving the nigiri sushi A away from the proximity sensor 18, as shown in FIG. Thereby, the clearance gap between the front-end | tip of the piston rod valve 15 and the dripping opening part 14 is lose | eliminated. Thereby, dripping of the soy sauce S from a nozzle can be stopped.

  By such a series of operations, the soy sauce dripping device 10 according to the present embodiment eliminates the trouble of pinching the sushi A with hands or chopsticks when eating sushi and attaching the soy sauce S to the material. You can eat nigiri sushi A with plenty of margin, with little separation from shari.
