More specifically, the present invention relates to an improvement in a cleaning device for cleaning a filling valve.

2. Description of the Related Art Conventionally, as a rotary filling device, a rotary table provided rotatably, a bottle table provided at equal intervals in a circumferential direction of the rotary table for mounting containers, and a rotary table integrally formed with the rotary table. A filling liquid tank which is rotated and provided so as to be able to move up and down with respect to the rotary table, a filling valve which is arranged above each of the bottle stands in the filling liquid tank and fills the container with a filling liquid, A device provided with a cleaning device for cleaning a filling valve is known (for example, Japanese Patent Publication No. 52-23308). The cleaning apparatus of the above publication includes a cup provided at a position adjacent to the bottle base in accordance with the number of filling valves, and a driving means for moving the cup to a position immediately below the filling valve and a position deviated therefrom. When each filling valve is washed after the filling operation is completed, the cup is located at a position immediately below the filling valve and the filling liquid tank is lowered. As a result, each cup comes into pressure contact with the filling valve to open the filling valve, so that the cleaning liquid stored in the cleaning liquid tank flows through the filling valve, thereby cleaning the filling valve.

By the way, in the above-mentioned conventional cleaning device, for example, if the container on the bottle base is damaged for some reason during the filling operation of the filling liquid into the container,
It is necessary to stop the turntable to remove the debris of the container scattered on the bottle stand and the turntable. that time,
In the above-mentioned conventional apparatus, since the cup and its driving mechanism are arranged at positions adjacent to the bottle stand, they have a drawback that they hinder the work of removing the damaged container. In order to solve such a drawback, instead of providing each component of the cleaning device at a position adjacent to the bottle base,
It may be provided above the bottle stand, in which case,
There is a drawback that not only a drive mechanism for moving the cup of the cleaning device forward and backward, but also an elevating mechanism for raising and lowering the cup and pressing the cup against the filling valve is required.

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, the present invention provides a rotary table provided rotatably, a bottle table provided at equal intervals in a circumferential direction of the rotary table, and on which a container is placed. A filling liquid tank that is integrally rotated with the rotating table and that is provided so as to be able to move up and down with respect to the rotating table;
A rotary filling device provided with a filling valve disposed above each of the bottle stands in the filling liquid tank to fill the container with the filling liquid, and a cleaning device for cleaning the filling valves; A plurality of engagement shafts fixed downward to the bottom surface of the filling liquid tank, a guide shaft fixed upwardly to the rotary table, a rotation center of the rotary table, and a lower part of the filling liquid tank. A ring plate provided at a position and formed with an engagement hole through which each of the engagement shafts penetrates and a guide hole through which the guide shaft penetrates,
A connecting means for connecting and fixing the ring plate and the engagement shaft or releasing the connection state thereof, and a number of the filling valves provided in the circumferential direction of the ring plate in a number corresponding to the number of the filling valves. And a cup for collecting
A drive means for moving the cup to a position immediately below the filling valve and a position outside the filling valve is provided.

According to such a configuration, the cup and its driving mechanism can be positioned above the bottle stand, so that the work space around the bottle stand can be enlarged more than before. In addition, the cup can be brought into pressure contact with the filling valve by using the elevating mechanism of the filling liquid tank which is originally raised and lowered with respect to the rotary table. Therefore, there is no need for a special elevating mechanism for pressing the cup and the filling valve into contact. As described above, since the work space around the bottle stand can be expanded, even if the container being filled is damaged, the operation of removing the damaged container can be performed smoothly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. In FIGS. 1 and 2, reference numeral 1 denotes a rotary filling device for filling a container 2 with a predetermined amount of filling liquid. The rotary filling device 1 includes a rotating body 3 that is rotated in a clockwise direction. The rotating body 3 includes a lower rotating table 4 and a filling liquid tank 5 provided above the rotating table 4. Rotary table 4
Are provided at the circumferentially equidistant positions of the bottles 6 on which the container 2 is placed and moved up and down. Further, the bottom surface of the filling liquid tank 5 above the bottle stands 6 has a conventionally known configuration. A filling valve 7 is attached. A gripper 8 for gripping the container 2 on each bottle base 6 is disposed at a position adjacent to each bottle base 6, and the gripper 8 is used to hold each bottle 6.
The container 2 placed on top is gripped so that the center of the container 2 matches the center of the filling valve 7, and the container 2 is prevented from dropping from the bottle base 6. Each bottle base 6
A rotatable cam follower 12 is attached outside the lower end of the support shaft 11 slidably penetrating the rotary table 4. The cam follower 12 is mounted on a lifting cam 14 fixed to a frame 13. The elevating cam 14 surrounds the rotation center of the rotary table 4 and is continuous in the circumferential direction. The cam curve is set as follows. That is, in the movement section A of the turntable 4 from the position of the discharge starwheel 15 to the position of the supply starwheel 16 in the clockwise direction in FIG. 1, the bottle base 6 is set at the lowermost position. Further, in the next moving section B after the moving section A, the bottle base 6 gradually rises from the lowermost end to the rising end, and in the next moving section C, the bottle base 6 is moved while being located at the rising end. Is set to Then, in the moving section D after the moving section C,
Gradually descends from the rising end to the lowermost end, and then returns to the above-mentioned moving section A, so that the bottle base 6 is moved while the moving section A is located at the lowermost end. Therefore, when the empty containers 2 are conveyed to the position of the rotary filling device 1 by the conveyor 17, the containers 2 are sequentially placed on the bottle base 6 moving in the moving section A by the supply star wheel 16. It has become. At this time, the container 2 on the bottle base 6 is gripped and centered by the gripper 8. Thereafter, the container 2 on the bottle base 6 is moved from the lower end to the upper end by moving in the moving section B, so that the nozzle 7a of the filling valve 7 is inserted into the upper end of the container 2 and Filling valve 7
The bottle opening packing is pressed against the upper end of the container 2. As a result, the filling valve 7 is opened, and filling of the container 2 with the filling liquid is started. In this state, while the container 2 on the bottle base 6 moves in the moving section C, the container 2 is filled with a predetermined amount of the filling liquid.
, The container 2 is lowered from the rising end to the falling end, so that the upper end of the container 2 is separated from the bottle packing of the filling valve 7. Therefore, the filling valve 7 is closed and the nozzle 7a is withdrawn from the container 2. Thereby, the filling of the filling liquid into the container 2 is completed. Thereafter, when the container 2 moves from the moving section D to the moving section A,
The container 2 is released from the gripping state by the gripper 8 and is discharged from the bottle base 6 to the transport conveyor 17 via the discharge star wheel 15. The filling liquid tank 5 of the present embodiment not only rotates integrally with the turntable 4 but also can move up and down with respect to the turntable 4, so that when the height of the container 2 is changed, The height position of the filling liquid tank 5 can be adjusted according to the height. Therefore, the filling liquid can be filled into the containers 2 having different heights by the filling valve 7 irrespective of the constant lifting stroke of the bottle base 6 by the lifting cam 14. The configuration in which the filling liquid tank 5 can be moved up and down with respect to the turntable 4 is described in, for example,
No. 23308 (U.S. Pat. No. 4,024,896)

The screw shaft 46 is linked to a motor (not shown) via a pinion 47 attached to its lower end and a worm gear 48 meshing with the pinion 47. Therefore, when the connection between the gripper 8 and the bottle base 6 is released by the lock mechanism 33, when the motor is rotated in the normal or reverse direction, the ring plate 37 and all the grippers 8 placed on the ring plate 37 are simultaneously moved up and down. The height position of each gripper 8 with respect to the bottle base 6 can be changed. Next, a lock mechanism 33 for integrally connecting the bottle base 6 and the gripper 8 will be described. As shown in FIGS. 3 to 5, the lock mechanism 33 includes a bracket 49 having one end fixed to the side of the bottle base 6. Have. A vertical through-hole 49a is formed in the other end of the bracket 49, and the through-hole 49a is slidably fitted on the support shaft 28 of the gripper 8. A horizontal through hole 49b is formed in the bracket 49, and the rotating shaft 50 is rotatably penetrated through the through hole 49b. At the inner end of the rotating shaft 50, a stopper 50a projecting in the radial direction is formed, and the stopper 50a faces the flat surface 28a formed in the outer peripheral axial direction of the support shaft 28. Let me. On the other hand, a lever 51 directed in the radial direction is fixed to the outer end of the rotating shaft 50, and a cam follower 52 is rotatably attached to the end of the lever 51. And, as shown in FIG.
An opening / closing cam 53 that engages with the cam follower 52 is provided at the center between the two star wheels 15 and 16 on the movement locus of the cam follower 52 when it moves. As shown in FIG. 5, the opening / closing cam 53 is composed of a pair of upper and lower cam members 53a and 53b which are integrally connected while maintaining a predetermined interval. The gap between them is enlarged by inclining the coming side (the right side in the drawing). This opening / closing cam 5
3 is connected to an air cylinder (not shown) mounted vertically upward on the frame 13, and when the air cylinder is not operated, the opening / closing cam 53 is located at the lower end shown by the imaginary line in FIG. . On the other hand, when the air cylinder is operated, the opening / closing cam 53 is raised to the position of the rising end shown by the solid line, and is stopped at that position. When the rotary table is rotated once while the opening / closing cam 53 is stopped at the rising end, each cam follower 52 sequentially engages with the cam surface of the opening / closing cam 53. The stopper portion 50a provided at one end of the rotating shaft 50 is rotated by a predetermined angle.
To the flat surface 28a. Thereby, each gripper 8 and each bottle base 6 are integrally connected. During the filling operation of the filling liquid into the container 2 by the filling valve 7, the opening / closing cam 53 is stopped at the rising end. Therefore, during the filling operation, each gripper 8

On the other hand, when the connection between each gripper 8 and each bottle base 6 is released, when the rotary table 4 is rotated once while the opening / closing cam 53 is located at the lower end shown by the imaginary line, each cam follower 52 is opened and closed. The rotation shaft 50 is sequentially engaged with the cam surface 53.
Is rotated clockwise by a predetermined angle.
Is separated from the flat surface 28a of the support shaft 28, and the connection between each gripper 8 and each bottle base 6 is released. Each gripper 8, which has been disconnected from each bottle base 6, descends to a position where the roller 36 is placed on the ring plate 7 by its own weight. Further, in this embodiment, as shown in FIG.
A screw hole 49c reaching the through hole 49b is formed in the bracket 49 by screwing.
4 and the tip of the screw 54 and the rotating shaft 5
The compression spring 55 is elastically mounted between 0 and 0. With this configuration, when the stopper 50a is separated from the flat surface 28a of the support shaft 28 and the connection between the bottle base 6 and the gripper 8 is released, the rotation shaft 50 is rotated by the weight of the stopper 50a. And the release state of each gripper 8 and each bottle base 6 can be reliably maintained. In the present embodiment, the above-described elevating device 23 is configured by the elevating mechanism 35 that elevates and lowers the gripper 8 and the lock mechanism 33 that connects the gripper 8 and the bottle base 6. According to the above-described configuration, when the height of the container 2 to be processed is changed, the gripper 8 is positioned at the predetermined height with respect to the bottle base 6 by the elevating device 23,
Thereby, the neck 2a of the container 2 on the bottle base 6 can be gripped. That is, for example, when the container 2 to be processed by the rotary filling device 1 is changed to a container 2 having a height higher than that previously processed, the filling liquid tank 5 is raised with respect to the rotary table 4. Then, the filling valve 7 is positioned at a height suitable for the lifting stroke of the bottle base 6. Next, the opening / closing cam 53 is positioned at the lower end shown by the imaginary line in FIG. 5, and the rotary table 4 is rotated once in this state. Thereby, the connection state between the gripper 8 and the bottle base 6 is released.
Thereafter, the motor (not shown) of the elevating mechanism 35 is driven to raise the ring plate 37 by a required amount, and the gripper 8 raised by the ring plate 37 moves the neck 2a of the container 2 changed by the arms 24A and 24B. The ring plate 37 is stopped at a height position where it can be gripped. Thus, the heights of all the grippers 8 can be changed at the same time. Next, in this state, the opening / closing cam 53 is positioned at the rising end shown by the solid line in FIG. 5, and the turntable 4 is rotated once in this state. Thereby, the gripper 8 and the bottle base 6 are integrally connected. Thereafter, the work of filling the filling liquid may be performed by rotating the turntable 4 in the same manner as described above. As described above, according to the present embodiment, even when the size of the container 2 is changed and the height of the container 2 is changed, the neck 2a of the container 2 can be gripped. The versatility of the device 1 can be improved. Further, in general, when the size of the container 2 is changed, the amount of change in the diameter of the neck 2a of the container 2 is much smaller than the amount of change in the diameter of the body of the container 2, so that
As in this embodiment, the neck 2 of the container 2 is
If a is grasped, the range which can be used for both becomes large. Moreover, even if the shape of the body of the container 2 is square or tapered, the neck 2a of the container 2 often has substantially the same shape, so that various types of containers can be used without replacing the gripper 8. 2 can also be used, so that the versatility of the rotary filling device 1 can be further improved. (Cleaning Apparatus) Next, the cleaning apparatus 18 will be described with reference to FIGS. In contrast to the conventional cleaning device in which the cleaning cup 21 and its driving mechanism 57 are provided at an inner position adjacent to each of the grippers 8 and the bottle base 6, in the present embodiment, the cup 21 and its driving mechanism 57 are provided. Is provided at a lower position adjacent to the filling liquid tank 5 to enlarge the working space around the bottle base 6 of each gripper 8. In addition, the cleaning cup 21 is pressed against the filling valve 7 by utilizing the above-described structure in which the filling liquid tank 5 can be moved up and down. That is, the cleaning device 1
8 is a ring plate 58 above the turntable 4.
The bottom surface of the ring plate 58 is provided with a plurality of cylindrical portions 58a protruding at a plurality of positions in the circumferential direction, and guides the inner peripheral surface of the cylindrical portion 58a and an upper through hole continuous therefrom. The hole 58b is formed. On the other hand, on the inner upper surface of the rotary table 4, stepped guide shafts 59 whose upper side is reduced in diameter are provided upright at a plurality of locations in the circumferential direction. Hole 58b
Slidably penetrates through. Further, as shown in an enlarged manner in FIG. 9, cylindrical portions 58c are formed at three positions in the circumferential direction of the ring plate 58 located on the inner side of the guide shaft 59. An engagement hole 58d is formed by the inner peripheral surface of the hole 58c and the through hole continuous therefrom. A stepped engagement shaft 60 whose diameter is reduced on the lower side is fixed to the bottom surface of the filling liquid tank 5 facing the engagement hole 58 d. The small diameter portion 60 a of the engagement shaft 60 is The hole 58d is made to penetrate. At a predetermined position in the axial direction of the small-diameter portion 60a that penetrates through the engagement hole 58d and protrudes from the cylindrical portion 58c, an engagement hole 60b that penetrates in the radial direction is formed, as shown in FIG. By inserting the stopper pin 61 into the engagement hole 60b in a state where the tip of the small diameter portion 60a passes through the engagement hole 60b,
The ring plate 58 and the filling liquid tank 5 are integrally connected. The stopper pin 61 is connected to the piston of the air cylinder 62 so as to move forward and backward. When the stopper pin 61 is moved backward from a forward end position shown in FIG. 9 to a retracted end position (not shown), the stopper pin 61 is engaged. Since it is withdrawn from the hole 60b, the connection state between the ring plate 58 and the filling liquid tank 5 is released at that time. In this embodiment, when the stopper pin 61 is removed from the engagement hole 60b, the cylindrical portion 58a of the ring plate 58 is placed on the step portion 59b of the guide rod 59 as shown in FIG. Until the filling liquid tank 5 is lowered. In this embodiment, the stopper pin 61 and the engagement shaft 6
The ring plate 58 and the engaging shaft 60 constitute a connecting means for connecting or releasing the connecting state between the ring plate 58 and the engaging shaft 60 by the zero engaging hole 60b.
Any connection means may be used as long as the connection means can be connected or the connection state can be released. As shown in FIG. 8, on the outer peripheral portion of the upper surface of the ring plate 58, support pins 63 are provided upright by the number of the filling valves 7, and cylindrical members 64 are rotatably fitted on the support pins 63, respectively. ing. Projections 64a and 64b are formed on the outer peripheral portion of each cylindrical member 64 so as to project at a predetermined angle in the radial direction, and the cup 2 is attached to the tip of the upper projecting portion 64a.
1 is fixed. On the other hand, the lower protruding portions 64b which are adjacent positions are connected to each other via a link mechanism 65. One of the cylindrical members 64 includes a ring plate 58.
The air cylinder 66 provided above is linked. When the air cylinder 66 is advanced to the forward end position indicated by the solid line in FIG. 8, all the cups 21 are simultaneously moved to the advanced end position indicated by the solid line via the link mechanisms 65. In that position, all cups 21 are located immediately below the filling valve 7. On the other hand, when the air cylinder 66 is retracted, all the cups 21 are retracted to the retracted end positions indicated by imaginary lines via the respective link mechanisms 65. In that position, all cups 21
Are located on the inner side of the center between the adjacent filling valves 7. (Operation) As shown in FIG. 2, the cleaning device 18 configured as described above keeps the ring plate 5
8 is integrally connected to the filling liquid tank 5, so that it is located at an upper position indicated by an imaginary line, and each cup 21 is supported inside the center position of the adjacent filling valve 7. On the other hand, when the filling device 7 is cleaned by the cleaning device 18 after the filling operation is completed, the cleaning is performed in the following order. First, after filling liquid remaining in the filling liquid tank 5 is discharged, the cleaning liquid is stored in the filling liquid tank 5. Next, the filling liquid tank 5 is lowered, and the cylindrical portion 58 a of the ring plate 58 is guided by the guide shaft 59. At the position where it comes into contact with the stepped portion 59a (the position indicated by the solid line in FIG. 2). When this state is reached, the stopper pin 61 is retracted by the air cylinder 62, and the stopper pin 61
From the engagement hole 60b of the engagement shaft 60. Thereafter, when the filling liquid tank 5 is raised to the position of the original rising end, the connection state between the ring plate 58 and the filling liquid tank 5 is released, so that the ring plate 58 is supported by the step portion 59 b of the guide shaft 59. Is done. In this state, all the cups 21 are simultaneously advanced by the air cylinder 66 to the advanced end position shown by the solid line in FIG. by this,
All the cups 21 are located immediately below the filling valve 7. Next, when the filling liquid tank 5 is lowered again by a required amount from this state, the bottle port packing of the filling valve 7 and the cup 21 are pressed against each other, and the filling valve 7 is opened. Therefore, the cleaning liquid stored in the filling liquid tank 5 flows through the filling valves 7, and the respective filling valves 7 are cleaned. The cleaning liquid flowing through each filling valve 7 is collected in a collection tank (not shown) via the cup 21 and the drain pipe 22. Thereafter, the filling liquid tank 5 is raised again to the original position, so that the pressure contact state between the filling valve 7 and the cup 21 is released, and the filling valve 7 is closed. Thereafter, when all the cups 21 are retracted to the retracted position by the air cylinder 66, the filling liquid tank 5 is lowered until the engagement shaft 60 passes through the engagement hole 58b of the ring plate 58. The stopper pin 61 is advanced by the cylinder 62, and the stopper pin 61 is inserted into the engagement hole 60b. Thus, the ring plate 58 and the filling liquid tank 5 are integrally connected. Thereafter, when the filling liquid tank 5 is raised to the original position, the ring plate 58 (the cleaning device 18) integrated with the filling liquid tank 5 also returns to the position shown by the imaginary line in FIG. Thereby, the cleaning device 1
The cleaning operation of the filling valve 7 by 8 is completed. As described above, in the cleaning device 18 of the present embodiment, the cup 21 and the driving mechanism 57 thereof are disposed below the filling liquid tank 5 so as to be separated from the periphery of the gripper 8 and the bottle base 6. Therefore, for example, if the container 2 on the bottle 6 is damaged for some reason during the filling operation, the cleaning device 18 is hindered in removing the damaged container from the bottle 6 and the turntable 4. No. Therefore, the cup 21 and its driving mechanism 5 are provided around the gripper 8 and the bottle base 6.
The cleaning work around the bottle base 6 becomes easier as compared with the related art in which the container 7 is provided. Further, in the present embodiment, when the cup 21 and the filling valve 7 are brought into pressure contact with each other, since the originally provided elevating mechanism of the filling liquid tank 5 is used, the cup 2
There is no need to provide a special elevating mechanism for pressing the 1 and the filling valve 7 in pressure. In the present embodiment, the cup 21
The filling valve 7 is opened by pressing the container 21 and the filling valve 7. However, in the case of a filling valve 7 that can be opened and closed without being pressed against the cup 21, the cup 21 and the filling valve 7 are separated from each other. In this state, the filling valve 7 is opened, and the cleaning liquid falling from the filling valve 7 may be collected by the cup 21.

As described above, according to the present invention, the working space around the bottle stand can be enlarged as compared with the conventional case, so that even if the container being filled is damaged, it is possible to increase the working space. The effect that the operation of removing the damaged container can be performed smoothly can be obtained.
