- the rotation drive force is transmitted from the turning mechanism 19 to be described later, and the three rotating shaft bodies A4 rotate the transfer units 16a to 16c so that the transfer units 16a to 16c are synchronized.
- the transfer units 16a to 16c have a function of transferring the container C between the respective units, and also have a function as a transport mechanism of the container C.
- the rotation direction of the transfer units 16a to 16c is opposite to the rotation direction of the measuring unit 13, the stock unit 14, and the discharge unit 15. Thereby, the container C is moved in the same direction on the side where each of the transfer units 16a to 16c and the measuring unit 13 and the like transfer the adjacent container C. Therefore, the delivery of the container C can be performed smoothly.
- a claw member 45 is provided near the delivery portions 16a to 16c as shown in FIG.

Delivery of Container C to and from Part 13 respectively.
- the turning mechanism 19 provided in the weighing device 10 of the present embodiment is a mechanism that applies a rotational driving force to the weighing unit 13, the stock unit 14, the discharge unit 15, and the transfer units 16a to 16c. As shown in FIG. 1, it is arranged below the weighing device 10. And, as shown in FIG. 12, the turning mechanism 19 includes a rotation motor Ml and a transmission unit 19a.
- the transmission unit 19a includes a rotating shaft Al for rotating the measuring unit 13, a rotating shaft A2 for rotating the stock unit 14, a rotating shaft A3 for rotating the discharging unit 15, and a rotating shaft A4 for rotating the transfer unit.
- the rotation driving force of the rotation motor Ml is transmitted via gears, pulleys, and a belt (not shown). Then, the rotating shaft bodies A1 and A4 are rotated so that the measuring section 13, the stock section 14, and the discharge section 15 are synchronized.
- the adjacent units are rotating the container C at the same speed. Therefore, it is possible to smoothly transfer the container C held in each part.
- the rotating shaft body A4 is for rotating the transfer units 16a-16c that rotate in the opposite direction to the measuring unit 13, the stock unit 14, and the discharge unit 15. For this reason, in the weighing device 10 of the present embodiment, with respect to the rotating shaft A4, the transmitting unit 19a converts the rotation direction to reverse rotation to transmit the rotational driving force.
- the weight of the object newly added to the container C can be determined by subtracting the measurement result in S2 from the measurement result in S4. Then, the weight of the weighing object in the container C is added to the weight of the newly added weighing object, and the weight of the weighing object in the container C, which is already stored, is used as a weighing result. be able to.
- the weighing unit 13 transmits the weighing result to the control unit 20.
- the control unit 20 stores the received weighing result of the weighing object in a storage unit such as a ROM or a RAM, and accumulates data for performing combination weighing.
- the weighed container C is received from the delivery unit 16a by the holder 31 of the storage unit 30. Subsequently, in S12, the received container C is circulated (standby) in the stock unit 14 while being held in the storage unit 30 until the received container C is selected by the control unit 20.

Stored in the means. Then, upon receiving a selection request from the control unit 20 in S13, in S14, the container C for which the selection request has been made is moved in the vertical direction.
- the selected container C is moved to a height position corresponding to the level 5F of the transfer unit 16b as shown in FIG.
- the container C requested to be selected is delivered to the delivery unit 16b.
- the container C delivered to the delivery unit 16b proceeds to S21 shown in FIG.
- the stock unit 14 holds the delivered container C, and the measuring unit 13 also refills the new storage container C at the position of the storage unit 30.

Therefore, the process from handing over the container C to receiving the new container C can be smoothly performed only by turning the storage unit 30 as it is. Further, in the storage unit 30, a new container C is additionally refilled at the position where the delivered container C is held. Therefore, the container C can be additionally refilled without moving the storage unit 30 in the vertical direction. Therefore, the amount of movement of the container C can be reduced, and the impact applied to the object placed in the container C can be reduced, and the object to be weighed can be protected.

- the discharging unit 15 moves the container C in the vertical direction and rotates the container C by 180 degrees. Thereby, a vertically upward inertial force can be applied to the object to be weighed. For this reason, even when there are multiple objects to be weighed in Container C, the objects to be weighed are solidified at the bottom of Container C, and the container C is rotated and the object to be weighed is immediately discharged from Container C. Can be prevented, and tailing can be prevented.
- the container C is moved in a vertically downward direction after the discharge unit 15 inverts the container C by 180 degrees.
- multiple objects to be weighed such as potato chips are put in container C! / If the container C is simply inverted to discharge multiple objects to be weighed, There is a time difference between the object to be weighed that is discharged to container C and the object to be weighed that is also discharged to container C at the end. In this case, the object to be weighed is discharged from the container in the form of an elongated strip, which causes a so-called tailing problem.
- the discharging unit 15 moves the container C vertically downward after the reversal of the container C. , A downward force can be applied to the vertical direction. Therefore, there is no time difference between the discharge of the object to be weighed which is first discharged from the container C and the discharge of the object to be discharged which is the last to be discharged from the container C, so that the problem of tailing can be solved.
- the discharge section 15 the case where the container C is inverted and the object to be weighed is discharged, and the case where the container C with the object to be weighed is delivered to the weighing section 13 without turning over! It can also be controlled.
