Description

[Detailed description of the invention] This invention relates to a device that automatically opens the filling valve when cleaning the storage tank of a liquid filling machine that automatically fills a container such as a bottle with a predetermined height with a fixed amount of liquid. be.

As a conventional device of this type, there is a device equipped with an annular lifting frame with a push-up piece that pushes up all the filling valves at once against the filling pulp that is pushed open by the top end of the container to be filled.

However, the conventional device requires a fluid pressure drive device to drive the annular lifting member, and has the drawback that adjustment after installation is troublesome and the manufacturing cost of the liquid filling machine increases.

There is also a valve opening/closing tool which is pivotably pivoted to the upper end of a support member fixed to a container holder via a shaft and a spring (see Japanese Utility Model Publication No. 12626/1983).

In this case, the valve opening/closing tool is raised and retracted so as not to interfere with the filling operation, but such a retracted state is unstable in high-speed rotation filling machines.

In view of this, this proposal provides a device for opening the filling valve when cleaning a liquid filling machine, which has an extremely simple mechanism, does not require adjustment, and is free from any risk of malfunction. The tube 14 and the guide tube 14 are pierced vertically,
The upper end is opened into the storage tank 12 and the enlarged head 15 is opened.
Exhaust pipe 1 with the lower end marked A opened at a predetermined height position
5, and a filling pulp 3 having an elastic pulling habit whose upper part fits into the guide tube 14 and whose lower end closely contacts the lower end of the exhaust pipe 15, and which is attached to the upper and lower parts of the cam follower 11 that follows the rail cam 10. In a liquid filling machine in which the filling valve 3 is opened and closed by a container 1 to be filled placed on a container holder 5 to be filled which moves up and down by directional displacement,
The container 10 to be filled has a height such that the upper surface 6a faces a position slightly lower than the top mouth end 1a of the container 10 to be filled at a predetermined height placed at a fixed position on the container pedestal 5, and has an arcuate inner edge 6b. an upper member 6B having a shape that does not interfere with the container to be filled 1;
The upper member 6B and the pin 9 are fixed to the container holder 5 to be filled.
, 9, the lower member 6 is removable and can be pulled upward.
This is a filling valve opening device for cleaning a liquid filling machine, which is provided with a filling valve opening arm 6 consisting of A.

Next, an embodiment of the present invention will be explained with reference to the drawings.
As shown in the partially cutaway side view of the moment when the gasket 4 of the filling valve 3 comes into contact with the filling valve 3, the device of the present invention is capable of handling the filling container 1 placed at a fixed position on the filling container pedestal 5 (in this embodiment). In the example, the height is set so that the top surface 6a faces a position slightly lower than the top end 1a of the can, but it is natural that it may be a bottle, so that it does not interfere with the container 1 to be filled. To prevent this, a filling valve opening arm 6 having a shape and size as shown in the plan view in FIG. 2 is attached to the filling container holder 5.

The arm 6 has a lower member 6A fixed to the end of the filling container holder 5 near the center of the filling machine by bolts I and nuts 8, and is detachable by being able to be pulled upwards by pins 9, 9 implanted in the lower member 6A. It consists of an upper member 6B.

As is clear from the second diagram, the upper member 6B has an arcuate inner edge 6b that surrounds the container 1 to be filled approximately 215 times around the center of the filling machine, and the container holder 5 to be filled is fixed to the frame side. It is a member that moves up and down together with the container 1 to be filled by vertical movement of the cam follower 11 that follows the rail cam 10, and is removed during normal filling.

The filling pulp 3 is inserted into the filling head attachment port 13 at the bottom of the storage tank 12.
The inner edge 3a of the lower end is in close contact with the enlarged head 15A of the lower end of the exhaust pipe 15, which is a pipe member that slides vertically inside the guide tube 14 attached to the storage tank and is fixed to the storage tank side, so that the inner edge 3a of the lower end is in close contact with the enlarged head 15A of the lower end of the exhaust pipe 15, which is fixed to the storage tank side. The container 1 to be filled resists the elastic pressing force of the spring 17 by pushing up the packing 4, which is adhered to the lower surface of the raw barley 16 and is fixed to the lower part, with the top mouth end 1a to prevent the liquid from flowing out. This is a valve that allows liquid to flow down when it rises.

The to-be-filled container holder 5 is a member that has a tendency to rise in response to the pressing force of a spring (not shown), and the rail cam 1
It has a cam follower 11 at the lower part that makes contact with the container 1 to be filled.
After receiving the liquid, it is raised to a predetermined position by the rail cam 10, and the container 1 to be filled can be filled.

The lid height between the top end 1a of the filled container 1 placed at a fixed position on the filled container pedestal 5 and the upper surface 6a of the arm 6 is such that the top end 1a is close to the packing 4 of the closed filling pulp 3. The container to be filled holder 5 which pushes up the container to be filled 1 after contacting the container 1 to be filled
It is set to be smaller than 0 stroke (for example, about 10 strokes).

The filling head 2 is arranged in an annular shape, and the planar movement path of the filled container holder 5 is also annular.

Since the present invention is configured as described above, when cleaning the inside of the storage tank 12, the upper member 6B of the arm 6 is attached to the lower member 6A, and the movement of the container holder 5 to be filled is started, and at the same time the cleaning is started. When the process starts, the container pedestal 5 on which the container 1 to be filled is not placed rises at the filling position, and the upper member 6B of the arm 6 pushes up the filled pulp 3, allowing the cleaning liquid to be discharged. .

Washing will be completed while the filling pulp 3 is opened several times, so after washing is completed, remove the upper member 6B of the arm 6.
Be prepared for filling work.

In this case, the lower member 6A is fixed on the container holder to be filled,
Since the upper member 6B is detachably attached to the lower member 6A via the pins 9, 9, the transition from the filling work position to the washing work position is quick and easy during cleaning after the completion of daily work, making the work extremely easy. Furthermore, by removing the upper member 6B, there are no parts that move during high-speed rotation filling work (it not only ensures work safety and reduces the manufacturing cost of the device, but also eliminates the need for adjustment). It has excellent advantages such as no problem and no risk of failure.
