Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a filling device for filling a container with a filling liquid, and more particularly to a lid opening/closing device for opening and closing a lid of a filling liquid tank.

``Prior Art'' Conventionally, a filling device generally includes a filling liquid tank for storing filling liquid and a filling valve attached to the filling liquid tank. It is becoming more and more filling. And this kind of filling equipment usually
The filling liquid can be filled into containers of different heights, and therefore, a lifting mechanism is provided to raise and lower the filling liquid tank and adjust the position of the filling valve to a height position that matches the size of the container. .

Further, the filling liquid tank is provided with a lid that closes its upper opening, and when cleaning the inside, the lid is removed first. Therefore, it has been proposed in the past that the filling liquid tank itself is provided with an lifting mechanism that lifts and lowers the lid to open and close it, separately from the lifting mechanism that lifts and lowers the filling liquid tank.

``Problems to be solved by the invention'' However, if a dedicated lifting mechanism for raising and lowering the lid of the filling liquid tank is provided, the manufacturing cost will of course increase, and it will be difficult to clean the entire filling device. Since it is also necessary to clean the dedicated elevating and lowering mechanism described above, there is a drawback that the cleaning work becomes complicated.

``Means for Solving the Problems'' In view of the above circumstances, the present invention includes a filling liquid tank for storing filling liquid, and a filling liquid tank that is removably provided with an upper opening of the filling liquid tank. a lid that closes; a filling valve that is provided on the filling liquid tank and fills the container with the filling liquid;
In the filling device, the filling device includes a lifting mechanism that lifts and lowers the filling liquid tank and adjusts the position of the filling valve to a height position that matches the size of the container. A second engaging portion that engages with the first engaging portion is provided on the supporting member provided in the support member in a manner corresponding to the raised position of the filled liquid tank and the lid body by the lifting mechanism, and both engaging portions are engaged with each other. In this state, the filling liquid tank is raised and lowered by the lifting mechanism to open and close the lid.

"Operation" According to the above-described configuration, when cleaning the filled liquid tank, the filling liquid tank is raised by the lifting mechanism and the first engaging part of the lid body is engaged with the second engaging part. Then, by lowering the filling liquid tank from this state using the elevating mechanism, the lid body can be opened to the filling liquid tank.

Therefore, there is no need for a dedicated lifting mechanism to lift and lower the lid as in the past, so manufacturing costs can be reduced compared to conventional equipment that has such a lifting mechanism, and the overall filling equipment cost is reduced. Since there is no room for cleaning the elevating mechanism when cleaning the lifting mechanism, the cleaning work can be made easier and at the same time, sanitary performance can be improved.

``Embodiment'' The present invention will be described below with reference to the illustrated embodiment. In FIG. 1, the rotary filling device is equipped with a disc-shaped rotary table 1 that rotates around a rotation axis provided on the right side (not shown). The rotary table 1 is provided on its outer periphery with a plurality of mounting tables 3 on which containers 2 are placed at equal intervals in the circumferential direction and are raised and lowered.

Further, an annular filling liquid tank 5 is attached to the rotary table 1 at an upper position via an elevating mechanism 4, and this filling liquid tank 5 is connected to the elevating mechanism 4.
The rotary table 1 is rotated integrally with the rotary table 1, and is also raised and lowered relative to the rotary table 1.

Furthermore, filling valves 6 are provided on the bottom of the filling liquid tank 5 so as to face each of the mounting tables 3, and empty containers 2 are placed on the mounting tables 3 from a star wheel (not shown). When the mounting table 3 is raised and the filling valves 6 are relatively inserted into the container 2, a predetermined amount of filling liquid can be filled into the container 2 from each filling valve 6.

Lifting mechanism 4 that lifts and lowers the filling liquid tank 5
are provided at three or more locations on a circle centered on the above-mentioned rotating shaft (not shown), and when the size of the container 2 is changed, by operating these elevating mechanisms 4 in synchronization all at once, The above filling liquid tank 5
can be raised and lowered.

Each of the elevating mechanisms 4 includes a large-diameter guide pipe 11 erected on the rotary table 1, a female threaded portion 11a formed on the upper inner periphery of the guide pipe 11, and a pivot support on the filling liquid tank 5. The screw shaft 12 has a screw shaft 12 screwed into the female screw portion 11a, and a gear 13 attached to the upper end of the screw shaft 12.

A ring-shaped sun gear 14 is rotatably supported on the filling liquid tank 5 about the above-mentioned rotating shaft (not shown), and the gears 13 of each lifting mechanism 4 are meshed with the ring-shaped sun gear 14. There is. Furthermore, a sprocket 15 is attached to the upper part of one of the gears 13, and the sprocket 15 is interlocked with a motor 17 provided in the filling liquid tank 5 via a chain 16.

Therefore, by rotating the motor 17 in the forward or reverse direction, the sun gear 14 can be rotated.
The screw shafts 12 can be driven to rotate in the same direction all at once through the gears 13, thereby making it possible to raise and lower the filling liquid tank 5.

The filling liquid tank 5 is equipped with a lid 18 that closes the upper opening 5a, and the lid 1
8 is fixed to the filling liquid tank 5 by a connecting bolt 19. Then, rectangular plate-like members 21 as first engaging parts are attached to bolts 2 at three positions equally spaced in the circumferential direction on the outer circumference of the upper surface of the lid body 18.
It is attached by 2.

During the normal filling operation of the rotary filling device, each of the plate-like members 21 is installed so as not to protrude outward from the outer periphery of the filling liquid tank 5, as shown by the solid line in FIG. When opening and closing the body 18, by attaching the plate member 21 in the opposite direction, as shown in the imaginary line in FIG. 1 and in FIG.
One end portion of the plate member 21 can be made to protrude outward from the outer periphery of the filling liquid tank 5.

And a post 23 erected on a frame (not shown)
In this case, when the filling liquid tank 5 and the lid body 18 are positioned at almost the upper end position by the lifting mechanism 4, each plate-like member 21 protruding outward from the outer periphery of the filling liquid tank 5 is engaged with. A U-shaped member 24 as a possible second engaging portion is fixed respectively.

In the above configuration, when filling the container 2 with the filling liquid, the lid 18 is integrally fixed to the filling liquid tank 5 by a connecting bolt 19, and a plate-shaped member attached to the lid 18 is attached to the lid 18. 21 is attached so as not to protrude outward from the outer periphery of the filling liquid tank 5, as shown by the solid line in FIG. Further, the height of the filling liquid tank 5 is determined by rotating the screw shafts 12 of each lifting mechanism 4 by the required amount in a predetermined direction simultaneously by the motor 17, to a height that matches the size of the container 2. has been adjusted to.

From this state, the rotary table 1 and the filling liquid tank 5 are rotated, and as described above, the empty container 2 is placed on the mounting table 3 by the star wheel (not shown), and the mounting table 3 is raised to fill the container. When the valves 6 are relatively inserted into the container 2, a predetermined amount of filling liquid is filled into the container 2 from each filling valve 6. When the filling operation is completed and the mounting table 3 is lowered and the filling valve 6 is pulled out from the container 2, the container 2 filled with the filling liquid is moved onto the mounting table 3 by a star wheel on the outlet side (not shown). will be removed from.

Next, when cleaning the inside of the filling liquid tank 5, first remove the mounting bolts 22, turn each plate member 21 in the opposite direction, and make a part of it protrude outward from the outer periphery of the filling liquid tank 5. Each plate member 21 is again fixed to the lid 18 using the mounting bolts 22 described above. Then, after starting the motor 17 and raising the filling liquid tank 5 to almost the upper end position by each lifting mechanism 4, the rotary table 1 and the filling liquid tank 5 are rotated by a required amount, and each of the plate-shaped The distal end of member 21 is engaged within U-shaped member 24.

Further, when the connecting bolt 19 connecting the lid 18 to the filling liquid tank 5 is removed to make the lid 18 and the filling liquid tank 5 separable, the motor 17 is rotated to connect the filling liquid tank 5. lower to the lowering end position. As a result, the lid body 18 is supported by each U-shaped member 24 via the plate member 21.
is raised relative to the filling liquid tank 5, so that the inside of the filling liquid tank 5 can be cleaned by opening the opening 5a.

Of course, when closing the lid 18, the reverse operation may be performed. Further, the plate-shaped member 21 and the U-shaped member 24 are not limited to these. For example, instead of them, a U-shaped bolt may be attached to the lid body 18, and on the other hand, the U-shaped bolt may be attached to the support column 23 through a chain. A hook that can be hung may be attached to the holder.

"Effect of the invention" As described above, according to the invention, it is sufficient to provide the first engaging part on the lid of the filling liquid tank and the second engaging part on the support member provided on the frame, which is different from the conventional method. Since a dedicated elevating mechanism for elevating and lowering the lid body is not required, there is no room for cleaning the elevating mechanism when cleaning the entire filling device, and therefore the cleaning work can be made easier. At the same time, sanitary properties can be improved, and manufacturing costs can be reduced compared to conventional devices provided with such a lifting mechanism.
