Description of the Related Art Conventionally, as a flow-type filling device, a tank for storing a filling liquid, a filling valve for filling the container with the filling liquid in communication with the tank, a control device for opening and closing the filling valve, and a filling valve A flow meter that measures the flow rate per unit time when the filling liquid is filled into the container by the control device, opens the filling valve by the control device, starts filling the container with the filling liquid, and fills the container with the filling device. It is known that a valve is closed to terminate the filling of the filling liquid into the container and the container is filled with a predetermined amount of the filling liquid (for example, Japanese Patent Application Laid-Open No. 2-191193, JP-A-9-2585). These conventional flow-type filling devices were made by paying attention to the fact that excess filling liquid is filled in the container during a period from when a closing signal is issued to the filling valve to when the filling valve is completely closed. Things. In order to solve such a drawback, in the apparatus disclosed in Japanese Patent Application Laid-Open No. 2-191193, every time a container is filled with a filling liquid, a difference between a target filling amount and a filling amount actually filled in the container is calculated. The timing for closing the filling valve at the next filling is determined based on the difference between the filling amounts. On the other hand, in the device disclosed in Japanese Patent Application Laid-Open No. 9-2585, for each flow rate when the filling valve is opened, the filling amount in the container from issuing a closing signal to the filling valve to completely closing the container is determined in advance. measure. And when actually filling the filling liquid into the container,
The closing timing of the filling valve according to the flow rate of the filling valve is determined by calculating backward from the previously measured filling amount.

た。In the apparatus disclosed in Japanese Patent Application Laid-Open No. 2-191193, the current filling operation is performed based on the error of the filling amount up to the previous filling. When the flow rate of the filling valve fluctuates, an error occurs between the filling amount after the filling and the target filling amount. On the other hand, in the apparatus disclosed in Japanese Patent Application Laid-Open No. 9-2585, it is necessary to perform the above-described measurement in advance according to the type and viscosity of the filling liquid to be processed, and such a preliminary measurement operation is complicated. There was a disadvantage.

である。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiment. In FIG.
Can be filled with a predetermined amount of filling liquid. The flow-type filling device 1 includes a rotating body 3 rotatably provided.
A tank 4 for storing a filling liquid is connected to an upper portion of the rotating body 3. Pipe 5 is placed at equal intervals in the circumferential direction of tank 4
Are connected to each other, and a filling valve 6 is attached to the end of each pipe 5. Each filling valve 6 can be switched between a large opening with a large flow rate and a small opening with a small flow rate when the filling valve 6 is opened. The switching operation between the degree and the small opening degree is controlled by the control device 6 for each filling valve 6. The configuration of the filling valve 6 capable of switching the opening degree at the time of opening between the large opening degree and the small opening degree is known in, for example, Japanese Patent Application Laid-Open No. 3-256894, and a detailed description of the configuration will be omitted. In the middle of each pipe 5, a conventionally known flow meter 7 is provided. Each flow meter 7 is provided in the pipe 5 when each filling valve 6 is opened to fill the container 2 with the filling liquid. The flow rate of the filling liquid per unit time flowing through the container 2, that is, the flow rate of the filling liquid filled in the container 2 per unit time is constantly measured, and the measured flow rate is input to the control device 8. On the other hand, below each filling valve 6, a bottle base 11 on which the container 2 is placed and which moves up and down is provided so as to be able to move up and down. Each bottle base 11 is rotated and transferred together with the rotating body 3, and is moved up and down in a predetermined area when the bottle base 11 is transferred. Then, the lower end of each of the filling valves 6 is inserted from above into the container 2 on each of the bottle bases 11 to be lifted, and in this state, the filling valve 6 is opened to fill the inside with the filling liquid. It has become. That is, when the lower end of each of the filling valves 6 is inserted into the container 2 on each of the bottle stands 11, the control device 8 first sends a signal to the closed filling valve 6 to open it with a large opening. (Time t1 in FIG. 2).
Since it takes a little time for the filling valve 6 to change from the closed state to the large opening degree, as shown in FIG. 2, the flow rate of the filling valve 6 gradually increases after issuing the command at t1, and a little time elapses. At time t2, the filling valve 6 has a large opening, and thereafter, the charging valve 6 is continued at the large opening. The flow rate per unit time by the filling valve 6 at this large opening is V1. Thereafter, at time t3 when the required time has elapsed since the filling with the large opening is continued, the control device 8 transmits to the filling valve 6 a command to switch from the large opening to the small opening. Since the switching of the opening degree of the filling valve 6 is not performed instantaneously, the flow rate of the filling valve 6 gradually decreases from the time point t3 when the command is issued, and the small opening degree of the filling valve 6 is reached at a time point t4. Switch to The flow rate per unit time by the filling valve 6 at this small opening is V2. After this, filling is continued for a required time at a small opening, and then
At a required time t5, the control device 8 transmits a command to the filling valve 6 to close the filling valve 6 from a small opening degree. Since the filling valve 6 is not closed momentarily after the closing command signal is issued, the filling valve 6 is gradually closed after the command to close is issued.
Is reduced and the filling valve 6 is completely closed at time t6, and the filling of the container 2 with the filling liquid is completed. The configuration described above is not different from the conventionally known configuration. In this way, the control device 8 opens and closes the filling valve 6 to fill the container 2 with the filling liquid. However, even if the control device 8 issues a closing signal to the filling valve 6 at the time t5 described above. , It takes time tx until the filling valve 6 is completely closed. Therefore, after confirming that the filling liquid filled in the container 2 matches the target filling amount Q to be filled in the container 2 at the time t5, the control device 8 sends a closing command signal to the filling valve 6. Even if it is discharged, the container 2 is filled with an extra filling liquid by an amount Qn indicated by oblique lines in FIG. Therefore, in the present embodiment, on the premise of the above-described configuration, the control device 8 issues a close command signal to the filling valve 6 and then completely closes the container 2 from the filling valve 6 until it is completely closed.
In anticipation of the expected filling amount Qn of the filling liquid to be filled into
The closing command timing from the control device 8 to the filling valve 6 is determined. That is, the control device 8 sets the target filling amount to be filled in the container 2 as Q, and opens the filling valve 6 from the time t1 to start filling the first container 2 as described above. Reference numeral 8 denotes an actual filling amount filled in the container 2 by the elapsed time after the start of filling and the flow rate measured by the flow meter 7 every time a predetermined time (for example, 2 msec) elapses from the start of filling. Q1 is calculated and obtained. Then, the control device 8 compares the filling amount Q1 calculated sequentially and the target filling amount Q, and when the calculated filling amount Q1 coincides with the target filling amount Q at time t5, the filling valve. 6 sends a closing command signal. This causes the filling valve 6 to be closed. However, the control device 8 issues a close command signal at time t5 and then actually fills the container 2 with the filling valve 6 until time t6 when the filling valve 6 is completely closed. The calculated excess filling amount Qn is calculated and obtained. Here, after issuing the closing command signal, the filling valve 6
Assuming that the time required to completely close the valve is tx and the flow rate measured by the flow meter 7 at the time t5 when the closing command signal is issued is v2, the following relationship is established. Qn = v2 · tx / 2 Based on this relationship, the control device 8 determines the required time tx from when the closing command signal is issued until the filling valve 6 is completely closed.
And memorize it. When the filling of the first container 2 is completed and the first container 2 is discharged from the bottle 11 and the second container 2 is supplied to the bottle 11, the control device 8 starts filling at time t1. After the valve 6 is opened to start filling, the control device 8 performs a predetermined time (for example, 2 msec) after the start of filling as in the case of the first filling described above.
Every time elapses, the actual filling amount Q1 filled in the container 2 up to that time is calculated from the elapsed time and the flow rate measured by the flow meter 7. At the same time, the controller 8 sets the flow rate of the currently open filling valve 6 (flow meter 7).
Based on the flow rate V1 and the required time tx, the filling valve 6 in the currently open state is filled in the container 2 until it is completely closed in response to the closing command from the control device 8. Is calculated. And
When the sum of the filling amount Q1 of the filling liquid already filled in the container 2 and the expected filling amount Qn matches the target filling amount Q to be filled in the container 2, the control device 8 issues a closing command to the filling valve 6. To close the filling valve 6. by this,
The filling liquid having substantially the same filling amount as the target filling amount Q is filled in the second container 2. Also, the control device 8
By issuing a closing command at the time of the second filling, the required time tx for closing the filling valve 6 is obtained as described above, and this is stored. Next, the second
When the filling of the container 2 is completed and the container 2 is discharged from the bottle base 11 and the third container 2 is supplied to the bottle base 11,
After the controller 8 starts the filling by opening the filling valve 6 from the point of time t1, the controller 8 performs a predetermined time (for example, 2) from the start of the filling similarly to the case of the second filling described above.
Every time (msec) elapses, the actual filling amount Q1 filled in the container 2 is calculated and obtained based on the elapsed time and the flow rate measured by the flow meter 7. At the same time, the control device 8 determines the current flow rate (flow rate measured by the flow meter 7) V1 of the filling valve 6 in the open state and the required time tx obtained at the time of the second filling. An expected filling amount Qn that will be filled in the container 2 until the filling valve 6 in the open state receives the closing command from the control device 8 and is completely closed is calculated. And the control device 8 has already
When the sum of the filling amount Q1 of the filling liquid filled in the container and the expected filling amount Qn matches the target filling amount Q to be filled in the container 2, a closing command is issued to the filling valve 6 to close the filling valve 6. Let it. Thus, the third container 2 is filled with the filling liquid having substantially the same filling amount as the target filling amount Q. In addition, the control device 8 issues a closing command at the time of the third filling, finds the required time tx for closing the filling valve 6 as described above, and stores this. Thereafter, the control device 8 repeats the above-described processing each time a new container 2 is filled. According to the above-described embodiment, it is not necessary to perform the preliminary measurement for obtaining the closing timing of the filling valve 6 as described in the section of the related art. In addition, since the filling valve 6 is closed based on the current flow rate of the filling valve 6 during the filling and the required time tx, the target filling amount Q and the actual filling amount in the container 2 can be matched. Therefore, the filling amount of the filling liquid into the container 2 can be managed with high accuracy without performing a measurement operation before filling. In the above embodiment, the closing timing of the filling valve 6 at the time of the current filling is determined based on the required time tx obtained at the time of the previous filling. Alternatively, the closing timing of the filling valve 6 at the time of this filling may be determined. Further, the required times tx obtained at the time of a plurality of past filling operations up to the last time may be averaged, and the closing timing of the filling valve 6 at the time of the current filling may be determined based on the averaged required time period. further,
The required time tx may be obtained by the control device 8 as follows. That is, the control device 8 starts the flow meter 7 from the time when the close command is issued to the filling valve 6 (at time t5 in FIG. 2).
The time elapsed until the measured value becomes zero (time t6 in FIG. 2) may be measured by a built-in timer or the like, and may be used as the required time tx. In the above-described embodiment, the case where the present invention is applied to a rotary filling device has been described.
Of course, the present invention can also be applied to a line-type filling device.
