Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a filling valve cleaning attachment (CIP attachment) applied to a food filling device.

[Conventional technology]

FIG. 5 illustrates a conventional filling valve cleaning attachment (CIP attachment) described in Japanese Utility Model Publication No. 59-23753.

1 is a filling valve body, and 2 is a CIP attachment for cleaning it. This attachment is attached to the cap 3 through a cap 3, a U-packing 5 which is fitted into the cap 3 and seals with the filling valve main body 1, and a spring 4 so as to be movable up and down, and an upper end of which abuts on a sealing gasket 9. It is composed of a ring member 6 and the like. In addition, a hole is formed in the lower part of the ring member 6 to allow the cleaning liquid to pass therethrough.
10 and a plurality of notches 11 are provided on the upper part.

The CIP attachment 2 is mounted by engaging a pin 12 provided on the filling valve body 1 with a groove 13 provided on the outside of the cap 3. (See FIG. 6) At this time, the outer end of the U-packing 5 is deformed by hitting the inner wall surface 1a of the filling valve body 1 to seal the gap between the cap 3 and the valve body 1.

On the other hand, the ring member 6 contacts the sealing gasket 9 by the action of the spring 4. In this state, the cleaning liquid is supplied from the flow path 8 to clean the inside of the filling ball main body 1 through the hole 10 and the notch 11 of the ring member 6 and finally discharged from the joint 7 and not shown. Collect by means.

[Problems to be solved by the device]

 The above-mentioned conventional technique has the following problems.

(1) Even if the centering between the U packing 5 and the outer end 1a of the filling valve body is subtly changed, the sealing performance is impaired, and there is no margin in the mounted state.

(2) One CIP attachment can support only one type of filling valve and nozzle.

(3) The mechanism inside the cap is complicated, and there are many parts such as U-packing recesses that are difficult to clean, and the hygienic property is poor.

An object of the present invention is to provide a filling valve cleaning attachment that can be attached to valve nozzles of different sizes and has a simple structure.

[Means for Solving the Problems]

Inside the filling valve cleaning attachment, a rubber ring that expands inward by introducing air pressure from the outside is provided as a sealing member for the filling nozzle in the filling valve.

[Action]

(1) By applying air pressure to the rubber ring at the seal portion with the filling nozzle, the rubber ring expands inward and the inner filling nozzle is tightly sealed. The large deformation of the rubber ring can cover the poor centering of the nozzle.

(2) Similar to (1) above, the same attachment can be used even if the nozzle diameter of the filling valve to be cleaned is slightly different.

(3) A one-touch attachment / detachment mechanism can accommodate a wide range of nozzle size changes.

(4) Since the rubber ring reliably seals only the outer circumference of the nozzle, there is no complicated part in the liquid contact part, and the hygienic property is good.

〔Example〕

1 to 4, 15 is a return pipe, 16 is a filling nozzle, 16a is a nozzle passage, 17 is a rubber ring, 19 is a cap, 20 is a ring, 21 is a holder, 22 is an O-ring,
23 is a joint, 24 is a cap mounting bolt, 25 is a flange,
26 is a seal plate, 26 'is a hollow cylindrical portion of the seal plate, 27 is a push pin, 28 is an O ring, 29 is a spring, 30 is a push spring, 31 is a lock plate, 32 is a seal plate mounting bolt, and 33 is a CIP. Head, 35 is a CIP head internal flow path, 36 is a flange internal flow path, 37 is a compressed air conducting path, 38 is a ring-shaped groove, 39 and 41 are lock plate insertion grooves, 40 is a lock plate slit, and 42 is a lock. Is a passage hole of the plate, 43 is an inner end of the hole 42 of the lock plate, and 44 is a dharma hole.

The return pipe 15 is a pipe for collecting the liquid from a plurality of CIP attachments, and a plurality of flanges 25 for mounting the CIP attachments are branched from this pipe.

The CIP head 33 constitutes a unit in which the cap 19, the ring 20 and the holder 21 are internally provided with the rubber ring 17, and is mounted on the seal plate 26 fixed to the flange 25 of the return pipe 15 by the bolt 32 as described later. It is detachably supported.

The rubber ring 17 is fitted in the ring 20, and its both side surfaces are fixed by the cap 19 and the holder 21 via the bolts 24. A slit 40 and a groove 39 are cut in the lower portion of the holder 21. When the lock plate 31 is inserted in the direction of the slit 40 and the groove 39 while the push pin 27 is pushed in, the push pin 27 is pushed out by the spring 29 into the daruma hole 44 of the lock plate 31, and the lock plate 31 is inserted into the daruma hole 44. With the push pin 27 and the pressing force of the spring 30
Held in place.

The lock plate 31 is pushed (in the direction of arrow R in FIG. 1), and the holder 21 is fixed on the flange 25 by the seal plate 26.
It is fitted in the cylindrical portion 26 '. The seal plate 26 seals between the holder 21 and the φ ring 28 mounted on the upper portion of the boss. Below the φ ring groove of the seal plate 26, the inner end 43 of the hole 42 of the lock plate 31 is
When the locking plate 31 is slid to the right (in the direction opposite to the arrow R), the hole 42 and the boss portion of the seal plate 26 are eccentric, so that the groove 41 is cut so as to be caught, and the holder 21 is fixed to the seal plate 26. Installed on the lock plate 31 with the push spring 30.
The inner end 43 of 42 is pushed into the groove 41 to prevent it from coming off.

The hole 42 of the lock plate 31 is slightly larger than the hollow cylindrical portion 26 'of the seal plate 26.

Next, the operation of this device will be described.

(1) The return pipe 15 is raised together with the CIP head 33, and the filling nozzle 16 of the filling valve (not shown) is inserted into the flow path 35 in the CIP head 33.

(2) When compressed air is supplied from the joint 23, air pressure acts on the outer circumference of the rubber ring 17 through the ring-shaped groove 38 through the conduction path 37, and expands the rubber on the inner diameter side.

(3) The expanded rubber ring 17 presses the outer circumference of the filling nozzle 16 and completely seals the nozzle flow path 16a and the outside air.

(4) In this state, the cleaning liquid is supplied from the channel 16a. The cleaning liquid is collected in the return pipe 15 through the flow path 36.

(5) To recombine CIP Head 33, take the following steps.

(5-1) When the lock plate 31 is pushed in with a finger, the inner end 43 of the hole 42 is disengaged from the groove 41 of the seal plate 26.

(5-2) Push pin 27 is the hole 4 in lock plate 31
4, the seal plate 26 is pushed up by the force of the push spring 29.

(5-3) You can pick up CIP head 33 only by holding your hand lightly.

(5-4) Before mounting, check that the lock plate 31 has been pushed in and the push pin 27 has popped out (state of FIG. 3). CI on the cylindrical portion 26 'of the seal plate 26
Insert it into the hole in the P
Is pushed in and the locking plate 31 is slid and fixed by the push spring 30 as before.

[Effect of device]

The present invention is a CIP head having a vertically penetrating flow passage and a part of the flow passage wall made of a rubber ring so that the rubber ring expands inward by supplying compressed air. A seal plate having a hollow cylindrical portion that is inserted into the lower end of the flow path of the head, and a member that supports the seal plate and discharges the cleaning liquid, and the upper end of the flow path of the CIP head has an opening for inserting a filling nozzle. Part and none
The following effects are produced by making the connecting portion between the CIP head and the seal plate detachable.

(1) The accuracy of centering between the CIP attachment and the nozzle is not required, and the sealing property is improved.

(2) Since the amount of deformation of the rubber for sealing is large, it is possible to double as a filling nozzle of different diameter size.

For example, φ10 to φ15 nozzles can be used in common.

(3) The cleanability is improved because there is no complicated shape inside.

(4) The CIP head can be easily replaced, and large changes in nozzle diameter can be easily dealt with.
