Description

  The present invention relates to a liquid filling amount measuring method and apparatus in a liquid filling and sealing device for a multi-chamber container, in which each chamber of a multi-chamber container having two chambers partitioned in the middle is individually filled with two kinds of liquids.

In the filling process of pharmaceuticals, etc., the filling amount is generally checked by manually pulling out a container filled with liquid, weighing it off with a balance installed off-line, taking out the contents, measuring the empty container, and subtracting it. To calculate the filling amount. Alternatively, the weight of the filled container is measured by a balance or a weight checker, and the weight of the empty container is subtracted from the weight of the filled container as the statistically processed weight to calculate the filling amount.
In any case, if there is a difference between the calculated filling amount and the target amount, an appropriate measure is taken to adjust the filling amount.

In a liquid filling device, for example, a filling amount is measured by a flow meter from a pressurized tank via a header (branch pipe), and a filling amount obtained by opening and closing a valve installed between the filling nozzle and the flow meter is stored in a container. Is filled. At that time, since the filling amount changes due to a change in flow rate and a change in the level of the tank, the filling amount is checked and the filling amount is adjusted at an appropriate frequency. However, in the filling process, in addition to the above-described fluctuation over time, an abnormal fluctuation may occur in the filling amount due to a sudden reason due to some trouble.
At that time, it is not possible to check for an abnormality in the filling amount due to a sudden reason by the conventional appropriate sampling check. Especially for pharmaceutical products, the filling amount is required to maintain extremely high accuracy, and since it is required to never give out defective products, the conventional sampling weights have become insufficient. In addition to the sampling weight, 100% inspection is performed by a weighing device. (Patent Document 2)

On the other hand, a bag called a multi-chamber container that can store two different types of liquids separately in one bag has recently been frequently used as a bag for filling medicines.

As shown in the plan view of FIG. 1, this multi-chamber container is formed in a vertically long bag shape with a soft synthetic resin, and the center position in the longitudinal direction is partitioned by a partition 2 (easy peelable seal). It is divided into a chamber A and a lower chamber B, and liquid filling ports 3 and 4 are opened in an unsealed manner in each of the chambers A and B. 4 is sealed, and when used, the partition 2 is peeled off to mix the two liquids, and is inserted into the center of the lower end of the lower chamber B and poured out through the welded port 5. As a filling method and a filling device, Patent Document 1 discloses a technique of filling and sealing a multi-chamber container by alternately raising both chambers from an inverted posture.
Japanese Patent No. 3437458 Japanese Patent Publication No. 7-65923

  In the multi-chamber container configured as described above, when each chamber is filled with liquid A and liquid B, one chamber is filled with a fixed amount from its filling port, sealed, and then refilled into the other chamber. It is necessary to fill and seal the liquid, and the filling amount must be controlled and further guaranteed. However, in the filling process, an abnormal change in the filling amount may occur due to a sudden cause due to some trouble other than a change over time such as a change in liquid amount or a change in tank level as described above. There is. At that time, an appropriate sampling check cannot check for an abnormal filling amount due to a sudden reason. Therefore, it is conceivable to weigh all the parts immediately after filling. In particular, in the case of a multi-chamber container, if the amount of filling in one chamber matches the excess or deficiency in the filling amount of the other chamber, the total weight will be processed as an acceptable product. There is a problem that the weighing of can not be properly handled.

The above problem can be solved by weighing the whole number offline before and after filling each chamber. However, the off-line weighing is slower than the filling speed. However, it was difficult to adopt.
The present invention has been made in view of the above-described problems, and measures the amount of filling in each of the upper and lower chambers of the multi-chamber container and increases the production speed and the production amount while maintaining the filling capacity of the filling machine. It is possible to achieve an increase in. In addition, by holding the container in the apparatus and positioning the filling port sealing process after filling as a multi-chamber container filling device, and weighing with the filling port securely sealed during weighing. An object of the present invention is to provide a method and an apparatus for measuring the liquid filling amount of a multi-chamber container with good productivity by reducing the time required for weighing as well as the certainty of weighing.

  In order to solve the above-mentioned problem, the method for measuring the amount of liquid filled in a multi-chamber container according to the present invention is formed in a vertically long bag shape by a soft synthetic resin, and the middle part in the longitudinal direction is divided by an intermediate partition part. In a method of intermittently transporting a multi-chamber container having a liquid filling port opened to each chamber, and standing up and alternating between the chambers of the multi-chamber container to fill and seal the liquid in both chambers, The tare mass is weighed with a first measuring instrument, the mass of a multi-chamber container filled with a predetermined liquid in one chamber is sealed with a second measuring instrument in an inverted position, and then the predetermined liquid is placed in the other chamber. The mass of the multi-chamber container filled and sealed with liquid in both chambers filled and sealed is weighed with a third weighing instrument in an inverted position, and the difference between the weighing value of the first weighing instrument and the weighing value of the second weighing instrument Is calculated as the filling amount of one chamber, and the difference between the weighing value of the second weighing device and the weighing value of the third weighing device is calculated It is characterized in that calculated as Hamaryou. By adopting such a configuration, it is possible to obtain an accurate product that can guarantee the filling amount of each chamber.

  Further, at this time, the weighing in the first to third measuring instruments of the multi-chamber container is preferably supported by supporting the mounting table by raising the measuring instrument from below the position where the multi-chamber container is not transported. Filled into each chamber of a multi-chamber container which is formed into a vertically long bag shape with a soft synthetic resin and is divided into an upper chamber and a lower chamber by dividing an intermediate portion in the longitudinal direction by an intermediate partition portion and a liquid filling port is opened in each chamber When the filling liquid is filled with different kinds of filling liquids, the filling liquid may be measured for each different kind.

  Further, the liquid filling and metering device of the multi-chamber container according to the present invention is formed into a vertically long bag shape by a soft synthetic resin, and a longitudinal intermediate portion is partitioned by an intermediate partition portion, and is divided into an upper chamber and a lower chamber. A filling device comprising a supply means for supplying a multi-chamber container having a liquid filling port opened therein and a delivery means for delivering the filled multi-chamber container, one end of which is supported by an endlessly rotating conveyor. A plurality of bases with perforations that are movable in a horizontal plane, and leg portions that are slidably pushed through the perforated portions of the bases on the upper surface of the base are disposed on the back surface thereof. A platform that is supported on the platform and is composed of two plates corresponding to the upper chamber and the lower chamber of the multi-chamber container, and is provided so as to be able to stand up alternately with the end portions adjacent to each other as fulcrums. Standing plates and standing plates that individually stand at predetermined positions on the conveyor rotation path When each chamber of the multi-chamber container stands up alternately at a predetermined position above the rotation path of the conveyor and the conveyor, the liquid filling machine for filling the chamber with the liquid and the filling port after the liquid filling are sealed. A sealing means, an inversion means for individually inverting the mounting plate at a predetermined position of the rotation path of the conveyor, and a weighing table provided at a predetermined position below the base of the rotation path of the conveyor. And a lifting / lowering means for raising the weighing means so that the weighing table can push up the lower end of the leg of the lifting / lowering base. It is characterized by that. By adopting such a structure, the filling amount of each chamber of the multi-chamber container can be accurately measured without being influenced by the conveyor with a compact structure.

  In this case, the weighing means in the apparatus includes the first multi-chamber tare weighing first meter, the second multi-measuring meter weighing and sealing one chamber, and the second chamber filling and sealing the other chamber. A third measuring instrument for measuring the chamber container is provided, and the delivery means includes a weight of one chamber from a measuring value of the first measuring instrument and a measuring value of the second measuring instrument, and a measuring instrument of the second measuring instrument. Device that eliminates a filled multi-chamber container from its delivery path when the filling amount calculated from the value and the measured value of the third measuring device is out of the respective predetermined management width It is good because defective products can be immediately excluded from the system by having the system attached. Furthermore, in the apparatus, the leg portion of the lifting platform has a configuration in which a portion that penetrates the perforated portion is formed in a columnar shape, and the whole is formed in a funnel shape. Thereby, the lifting platform can be stably supported on the base before and after weighing.

  As described above, in the present method or the present apparatus, on the production line for liquid filling and weighing of a multi-chamber container, a weighing device is disposed after weighing of empty containers and after filling on one side and after filling on the other side. Transports the inside of the device together with the base, lifts the measuring instrument at the weighing position, separates the base and the lifting base at the weighing scale of the measuring instrument, and measures the empty multi-chamber container and the multi-chamber container after filling. I can do it. Moreover, when filling and sealing, the chamber filled from the partition part of the multi-chamber container is erected substantially vertically with the mounting plate supported by the lifting platform joined to the base, and the position of the filling opening is accurately maintained Can be filled and sealed. According to these method or device of the present application, it is possible to perform 100% measurement without reducing the efficiency of filling and sealing.

  According to the present invention, the mass of the supplied empty multi-chamber container is weighed, and one side is alternately raised with respect to the other side with the partition portion of the multi-chamber container serving as a fulcrum position, from the filling port of each chamber. Each liquid is filled and sealed, the filling amount on one side is calculated, and the filling amount on the other side can be calculated. For example, one filling amount is excessive and the other filling amount is light. Thus, even if the total weight is within the standard value, it is possible to determine that the filling amount is defective and eliminate it as a defective product from the immediate conveyance path. Therefore, it is possible to reliably detect an abnormality in the filling amount caused by a sudden cause by weighing the filling amount at that time and to reliably eliminate defective products.

  Also, the measurement of the filling amount has an effect of eliminating the filling amount abnormality in the sealed state by sealing the filling port and performing in an inverted position. These do not require the use of complicated mechanisms, so that the apparatus can be simply and planarly configured. In the filling process and the sealing process, there are various advantages that a filling and weighing apparatus that performs high-precision operations can be performed with a compact apparatus and equipment with low equipment costs.

The weighing table 21 is provided below the position where the weighing means is disposed. Weighing so that the lower end of the can be pushed up It is arranged the lifting means using the air cylinder 22 to raise the stage.

The liquid filling and metering device M is arranged with one end thereof fixedly arranged so that a plurality of bases 11, 11,. .
The base 11 is provided with three perforated portions 12, 12, and 12, respectively. There is provided a lifting / lowering base 13 having a funnel leg 19 and a funnel-shaped part 18 which are slidably pushed through the perforated part 12, and is supported by the lifting / lowering base 13. There are provided mounting plates 15A and 15B which are constituted by two plate members corresponding to the upper chamber A and the lower chamber B and are provided so as to be able to stand up alternately with their adjacent ends as fulcrums. The funnel leg 19 is formed in a cylindrical shape at the portion that penetrates the perforated portion 12 and is formed in a funnel shape as a whole. Thereby, the position of the lifting platform 13 can be held or fixed to the perforated portion 12 by the funnel-shaped portion 18. In addition, the state in which the perforated part 12, the cylindrical funnel-shaped part 18, and the perforated part 12 are held or fixed by horizontally pushing up the three funnel legs 19 from the lower position of the base 11. A space is generated in the funnel leg portion 19 and the perforated portion 12, and the base 11 and the lifting platform 13 are surely separated. In addition, by releasing the horizontal push-up and lowering, the base 11 and the lift 13 can again hold the funnel-shaped portion 18 to the perforated portion 12 and hold or fix the position of the lift 13. It is as a structure. (Hereinafter, the lifting platform, mounting plate, etc. mounted on the base are collectively referred to as a bucket)

Next, the operation of the apparatus in each of the stations 101 to 112 of the conveyor N rotating endlessly to which one end of the base 11 is fixed will be sequentially described.
A supply station 30 for the multi-chamber container 1 is provided at one station 101 (see FIG. 2) at the starting end position of the base 11 or the bucket orbit, and the empty multi-chamber container 1 is supplied by the supply conveyor 34. It is transferred to the station 30, and the empty multi-chamber container 1 is supplied from the supply conveyor 34 to the horizontal bucket of one station 101, and the bucket 16 is provided on the mounting plates 15A and 15B. Thus, the upper and lower sides of the container 1 are held and held on the mounting plates 15A and 15B.
When the empty multi-chamber container 1 is held, the weighing table 21 of the measuring device 20 (first weighing) installed below the base 11 of the one station 101 pushes the lower end of the funnel leg 19 of the lifting platform 13. The measuring instrument 20 is raised by the air cylinder 22 so as to be raised. Cylinder 20 was lifted when weigher 20 was lifted, the bucket was lifted by weighing platform 21 and separated from base 11 to start weighing, and when the measured value was stabilized and the measured value was taken into the control device, cylinder 22 goes down. When the weighing platform 21 of the measuring instrument 20 is lowered and the lifting of the bucket is released, the bucket is held or fixed to the base 11 again. The weighing platform 21 of the weighing instrument 20 is moved down to a position where the bucket leg 19 of the bucket that is pushed through the perforated portion 12 of the base 11 does not interfere with the movement of the base 11 and the operation of one station is completed. .
