Detailed Description of the Invention

FIELD OF THE INVENTION The present invention relates to a gas filling and filling machine,
More specifically, the present invention relates to a method for removing a damaged piece mixed container in a gas filling and filling machine that removes a container that may be mixed with blown broken pieces when the container is broken during filling by a filling valve.

2. Description of the Related Art Generally, a gas filling and filling machine has a rotating body which is rotatably provided, and a plurality of bottle stands which are provided at equal intervals in the circumferential direction of the rotating body and on which containers are respectively placed.
Supplying means for supplying a container on each bottle base, a filling valve provided at equidistant positions in the circumferential direction of the rotating body, for filling a filling liquid into the container on each bottle base at high pressure, and each bottle described above. And a carrying-out means for carrying out the container on the table. In a gas filling filling machine, the filling liquid is filled into the container at a high pressure from the filling valve in a state where the mouth of the container is closely adhered to the filling valve and is sealed, but especially beer bottles that are collected and reused. In that case, the pressure may cause the bottle to rupture, in which case the bottle will be almost completely destroyed without being left in its original shape. The broken container is shattered by the pressure inside it and blows off around it, but a relatively strong bottle bottom and mouth may remain on the bottle base. Are prevented from being supplied to the bottle base. Therefore, conventionally, a damaged container detecting means for detecting the presence or absence of a damaged container that has been completely damaged during filling by the filling valve, and a signal from the damaged container detecting means for injecting water to detect the damaged container on the bottle base. A water jetting means for removing is provided, and at the same time, the water jetted from the water jetting means removes the damaged container on the bottle base, and at the same time scatters around the bottle base and adheres to normal containers and filling valves before and after. I try to remove the broken pieces. However, even if an attempt is made to remove a broken piece attached to the filling valve by the water injection means, it may not be completely removed, and such a broken piece may be mixed in the container together with the filling liquid at the time of the next filling. . For this reason, conventionally, regarding a filling valve that attempts to fill a broken container with a filling liquid, a container filled with the filling liquid by the filling valve is defective only a predetermined number of times, for example, three times after the container is broken. And the defective container is removed to the outside by a reject device (Japanese Patent Laid-Open No. Sho 56-56).
-13393).

However, when the container is shattered and scattered around the container due to the pressure at the time of filling, the broken pieces adhere not only to the filling valve but also to the filling valves before and after the filling valve. Sometimes. And the water injection means may not be able to completely remove the broken pieces attached to the front and rear filling valves, and such residual broken pieces fall into the container when the container is separated from the filling valve at the end of filling. It was easy or sometimes mixed with the filling liquid in the container at the time of the next filling. In view of such circumstances, the present invention provides a method for removing a container containing broken pieces in a gas filling and filling machine, which can reduce the risk that a container containing broken pieces is processed as a normal container. .

Means for Solving the Problems That is, the present invention is directed to a rotatably provided rotating body, and a plurality of bottle bases provided at equidistant positions in the circumferential direction of the rotating body for mounting containers, respectively. Supply means for supplying a container on the bottle base of
A filling valve that is provided at equal intervals in the circumferential direction of the rotating body and that fills the filling liquid into the container on each bottle base with high pressure, and detects the presence or absence of a damaged container that was damaged during filling by the filling valve. Damaged container detection means, water injection means for ejecting water by a signal from the damaged container detection means to remove the damaged containers on the bottle bases, carry-out means for carrying out the containers on the bottle bases, and defective containers With a rejecting device for removing from the normal container transfer line to the outside, while selecting the filling valve in which the container is damaged by the signal from the damaged container detection means, the number of predetermined times after the container is damaged. Damage to the gas filling and filling machine that selects the container filled with the filling liquid by the filling valve as the defective container only for a while, and removes the defective container to the outside by the reject device. In the method of removing a mixed container, when the container is damaged, a first step of selecting and removing a predetermined number of containers before and after the filling valve where the container is damaged as a defective container, and at least by the filling valve where the container is damaged The present invention is characterized in that a second step of selecting and removing the number of containers including the filled containers and smaller than the number of the containers selected and removed in the first step is provided.

According to the above method, a predetermined number of containers before and after the filling valve in which the container has been damaged in the first step can be selected and removed as defective containers. Even if they adhere and fall into the container when the container separates from the filling valve at the end of filling, such a container can be removed as a defective container from the normal container transfer line to the outside. Further, in the second step, at least the container filled with the damaged filling valve can be selected and removed as a defective container.
Similar to the method of Japanese Unexamined Patent Publication No. 13393, at least for a filling valve that attempts to fill the broken container with the filling liquid, the container filled with the filling liquid is defective for a predetermined number of times after the container is broken. It can be selectively removed as a container. In the second step, the number of containers to be selectively removed is smaller than the number of containers in the first step. Therefore, an appropriate number of containers can be selected according to the degree of risk of broken pieces being mixed in the container. Only the container can be selected as a defective container, and a normal container will not be excessively selected and removed as a defective container.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. Referring to FIGS. 1 and 2, a rotary gas filling and filling machine 1 is equipped with a rotating body 2, which is a rotating frame 3 on the lower side. And a rotary table 4 provided above the rotary table 4, and a filling liquid tank 5 provided above the rotary table 4. Bottle tables 7 for mounting and elevating the containers 6 are provided at circumferentially equidistant positions on the rotary table 4, and the bottom surface of the filling liquid tank 5 above the bottle tables 7 is conventionally known. Each of the filling valves 8 is attached. Each of the bottle bases 7 is attached to an upper end of a cylinder 9a that constitutes an air cylinder 9, and each cylinder 9a is vertically pierced through the rotary table 4. Also, the rod 9b that constitutes the air cylinder 9
Has its lower end fixed to the rotary frame 3, and when compressed air is supplied to each air cylinder 9, the cylinder 9
A can be biased upward. Then, a cam follower 9c is attached to the lower end of each cylinder 9a toward the outside of the rotary table 4, and when compressed air is supplied to each air cylinder 9 to urge the cylinder 9a upward, each cam follower 9c is moved. The cam 11 fixed to the fixed frame 10 can be brought into contact with the lower cam surface. The cam 11 is formed in a columnar shape so as to surround the rotating frame 3, and each cam follower 9c has a cam 11
It is designed to go up and down according to the cam curve of. At this time, the cam curve is set so that the bottle base 7 can be located at the lowermost end in the container loading / unloading section A from the loading / unloading star wheel 16 to the feeding star wheel 15 shown in FIGS. Yes, in the next container rising section B, the bottle base 7 is set so that it can be gradually raised to a required height. The cam 11 is omitted in the filling section C for filling the filling liquid into the next container so that each bottle base 7 can be raised to the rising end position in the filling section C. However, the bottle base 7 where the container 6 does not exist rises to the rising end position, but the bottle base 7 on which the container 6 is placed has the mouth of the container 6 before the bottle base 7 rises to the rising end position. Since it is pressed against the filling valve 8, it does not rise to the rising end position. Further, in the descending section D of the container following the filling section C, the bottle base 7 raised in the filling section C is gradually lowered so that the cam follower 9c can be delivered to the above-mentioned loading / unloading section A. . Therefore, in FIG. 1, the empty containers 6 transported by the transport conveyor 17 are sequentially placed by the supply star wheel 15 on the bottle table 7 moving in the loading / unloading section A. Thereafter, the bottle base 7 is gradually raised while moving in the rising section B, and when it reaches the filling section C, the mouth of the container 6 is pressed against the filling valve 8 and the inside of the container 6 is sealed. Then, similarly to a conventionally known gas filling and filling machine, first, pressure gas is supplied into the container, and when the pressure in the container reaches a predetermined value or more, the filling valve 8 is opened to fill the container 6 with the filling liquid. . When the container 6 is filled with a predetermined amount of the filling liquid, the filling valve 8 is closed, and then a sniff valve (not shown) is opened to gradually release the pressure in the container 6 to the atmosphere, so that the pressure in the container 6 is increased. When the atmospheric pressure is reached, the bottle base 7 moves to the descending section D. Then, since the container 6 is lowered in the descending section D, the container 6 is separated from the filling valve 8 and the filling by the filling valve 8 is completed. After this, the container 6 is transferred to the bottle stand 7 via the carry-out star wheel 16.
The sheet is discharged from above onto the conveyor 17 and conveyed to a capper or labeler (not shown). Next, the filling valve 8
The damaged container detection means 13 for detecting the presence or absence of a damaged container that has been damaged during filling by means of the damaged container detection means 13 will be described with reference to the damaged container detection means 13 shown in FIG. Detector 9 for detecting the presence or absence
9 is equipped. The signal from the detector 99 is adapted to be inputted to a control device (not shown), which also receives a signal from a detector (not shown) for detecting the rotational position of the rotating body 2 and thereby the container. It is possible to manage which position the bottle base 7 to which 6 has not been supplied is moved. Further, the damaged container detecting means 13 is, as shown in FIG.
And a detector 14 attached to the bracket 3a provided on the rotating frame 3 to detect that the protrusion 9d is at the rising end position.
The detector 14 is arranged at the upper end of the ascending / descending path where the protrusion 9d provided on the cylinder 9a is moved up and down. When the container 6 is supplied to the bottle base 7, the bottle base 7 is , The container 6 placed on the bottle base 7 is filled with the filling valve 8
Since the rise is stopped at the position where the protrusion 9d abuts, the protrusion 9d is not detected by the detector 14. On the other hand, the container 6 was not supplied on the bottle base 7, or even when the container 6 was supplied to the bottle base 7, the container 6 was completely damaged during filling by the filling valve 8 so that the container 6 could hardly keep its original shape. At this time, since the bottle base 7 is not regulated by the container 6 in the rising position, the bottle base 7 is lifted to the rising end position of the cylinder 9a. Therefore, in this case,
The detector 14 comes to detect the protrusion 9d. As described above, the broken container detecting means 13 detects the presence or absence of the container 6 by the detector 99 in advance and manages the position where the bottle base 7 to which the container 6 has not been supplied is moved. , The container 6 was not supplied, the bottle base 7 was raised to the rising end position, and the protrusion 9d of the bottle base 7 was detected by the detector 1
Even if it is detected by 4, the container is not judged to be completely damaged. On the other hand, regarding the bottle base 7 to which the container 6 is supplied, when the detector 14 detects that the bottle base 7 has been raised to the rising end position, the container supplied to the bottle base 7 is Judge as damaged. At this time, the control device monitors the movement of the bottle table 7 and
However, when the water is injected from the water injection means 18 when passing through the water injection means 18 arranged at the end of the filling section C in which the filling of the filling liquid into the container by the filling valve 8 is completed completely, , The damaged container 6a remaining on the bottle base 7
The broken pieces (see FIG. 4) and the broken pieces of the container attached to the filling valve 8 are removed. As shown in FIG. 4, the water jetting means 18 includes a water pipe 98 which is arranged adjacent to the rotating body 2 and fixed in the vertical direction, a hose 97 which supplies water to the water pipe 98 at a high pressure, and the water pipe 98. The pipe 98 is provided with a plurality of nozzles 96 for injecting water toward the bottle base and the filling valve 8. However, in the present embodiment, when the control device determines that the container is damaged, first, as shown in FIG.
Each of the three containers before and after the filling valve 8a that had been filled with the filling liquid in the damaged container 6a was selected as a defective container 6b, and
The reject device 20 shown by is operated to discharge a total of six defective containers 6b from the top of the transfer conveyor 17 which is a transfer line for normal containers to the outside. Next, as shown in FIG. 6, the controller controls the container filled with the filling valve 8a, which has filled the broken container 6a with the filling liquid, and the front and rear of the container when the rotating body 2 is rotated next time. Two containers are selected as defective containers 6b, and a total of five defective containers 6b are selected.
Is ejected from the transport conveyor 17 to the outside by the reject device 20. Further, as shown in FIG. 7, the control device further includes a container filled by the filling valve 8a that was filled with the filling liquid in the damaged container 6a and the front and rear of the container when the rotating body 2 is further rotated. One container is selected as a defective container 6b, and a total of three defective containers 6b are discharged from the transport conveyor 17 to the outside by the reject device 20. Then, the control device shown in FIG.
As shown in FIG. 5, when the rotating body 2 is further rotated, only the container filled by the filling valve 8a that has filled the broken container 6a with the filling liquid is selected as the defective container 6b, and the defective container 6b is sorted as The reject device 20 discharges it from the conveyor 17 to the outside. Then, after this, the control device returns the rotary gas filling and filling machine 1 to a normal operating state. Therefore, according to the above-described method for removing a broken piece-containing container, as for the filling valve 8a in which the broken container 6a is filled with the filling liquid, as in the method described in JP-A-56-13393 described above, Since the container filled with the filling liquid by the filling valve 8a for the next three times after being damaged can be selected and removed as the defective container 6b, the container in which the broken pieces are mixed is surely replaced with the normal container. It can be removed from the transfer line.
At the same time, not only the filling valve 8a in which the broken container 6a was filled with the filling liquid but also the preceding and succeeding containers are sorted and removed as defective containers. Even if it adheres to the front and rear filling valves and drops into the container when the container separates from the filling valve at the end of filling, such a container is removed as a defective container from the normal container transfer line to the outside. You can Further, since the risk that the broken pieces attached to the filling valve fall into the container is reduced as the distance from the filling valve 8a increases, the number of containers to be selectively removed decreases as the rotating body 2 rotates. Since it is possible to select only an appropriate number of containers as defective containers according to the degree of risk of broken pieces being mixed into the container, it is possible to eliminate normal containers as excessively defective containers. Can be prevented. In the above embodiment, the defective container 6b when the container is broken
Is set to a total of 6 containers in each of the three containers before and after the filling valve 8a, but may be set to a total of 4 containers in each of the two containers before and after the filling valve 8a. In this case, a total of 5 containers are removed as defective containers 6b when the rotating body 2 is rotated next time, and 3 containers and 1 container are sequentially defective due to the subsequent rotation of the rotating body 2.
Will be removed as. Furthermore, it goes without saying that the number of containers to be removed and the number of times of selective removal can be appropriately set depending on the state of attachment of blown broken pieces to the filling valve and the degree of removal of the attached broken pieces.

As described above, according to the present invention, there is an effect that a container having a risk of containing broken pieces can be reliably and effectively removed from a normal container transport line without waste. To be
