In addition, container 2 comprises the bottom that is arranged on neck 6 and ring 7 under mouth 3.

Filling element 1 mainly comprises (Figure 17):

Unshowned tank, described tank comprises pourable food products;

Carousel 8, it rotates around axle A, is vertical in the shown embodiment; And

Multiple filling 9 (only one of them being shown in Fig. 1-16), these filling 9 is arranged on the periphery of carousel 8, parallel to each other and extend along corresponding axle B alternately relative to axle A.

In detail, filling 9 receives cell therefor 2 at access station I from conveyer upstream, along the circular arc path P conveying cell therefor 2 with the center on axle A, and exports cell therefor 2 to conveyer downstream at output station O.

Periodically, filling element 1 experiences cleaning step, and during cleaning step, cleaning agent circulation flows into filling 9 to carry out disinfection to it.

At this specification sheets with lower part, only will describe one filling 9 in detail, obviously these filling 9 is mutually the same.

Comprise successively (Fig. 1-16) for filling 9:

Body 10;

Body 17;

Conduit 11 (being only schematically illustrated in Figure 11 and Figure 12), it is fluidly connected to tank and limits outlet mouth 12;

Valve 13 (being only schematically illustrated in Figure 11 and Figure 12), it is got involved along conduit 11; And

Can pour into product overflow from mouth 12 to not disturb, enclosed member 14 is configured in stop position in the normal filling period of corresponding container 2.

Specifically, during cleaning step, valve 13 is in open configuration, and cleaning agent can contact and clean whole conduit 11 and mouth 12 thus.

Accurately put, during cleaning step, enclosed member 14 is configured in control position again, prevents cleaning agent from overflowing from mouth 12 thus.

Usefully, filling 9 comprises actuator 15 (Figure 11 and Figure 12), and it may be operably coupled to enclosed member 14 and is suitable for mobile enclosed member 14 between stop position and control position.

Be important to note that, because actuator 15 is by corresponding filling 9 fact of carrying, therefore corresponding enclosed member 14 moves independently of one another between corresponding stop position and relevant work position.

Also sensor 20 (being only schematically illustrated in Figure 11 and Figure 12) is comprised for filling 9, when conduit 11 is in open configuration and in container 2 filling period, whether this sensor 20 can be damaged by inspection instrument 2.

With regard to functional perspective, sensor 20 is also connected to actuator 15.

In addition, when sensor 20 detects that container 2 is damaged, enclosed member 14 is moved to control position from stop position by actuator 15, hits the container 2 of damage thus and it is evicted from from filling 9.

In the illustrated embodiment, sensor 20 is pressure sensors, its pressure during container 2 pressurized in Sensing container 2.

In more detail, first enclosed member 14 is moved to midway location (just arriving after the position shown in Fig. 9 and Figure 10) from stop position (Fig. 3-6) along the first stroke by actuator 15, and along the second stroke, enclosed member 14 is moved to control position (Fig. 7 and Fig. 8) from midway location subsequently.

More Accurate Points is said, at midway location, enclosed member 14 is coaxial and be arranged on along axle B from the given distance of mouth 12 with mouth 12.

First stroke is parallel to the spiral stroke of axle B around axle C (Fig. 1, Fig. 2, Fig. 4, Fig. 6, Fig. 8 and Figure 11-14).In other words, along this first stroke, actuator 15 makes enclosed member 14 rotate around axle C simultaneously and make enclosed member along axle C towards mouth 12 translation.

Second stroke is the translation of enclosed member 14 along axle C.

See Figure 13 and Figure 14, filling 9 comprises the body 25 being connected to body 11.

Body 25 stretches out from body 11 and is configured in relative to axle A the opposite radial side of body 11.

In the shown embodiment, body 25 has along axle C and the length that staggers parallel with axle B, and is vertical in the shown embodiment.

Body 25 is hollow and limits cavity 24.

Body 25 comprises:

Be positioned at the top end wall 35 on horizontal plane; And

Be the sidewall 36 of cylindricality to axle C, it comprises shoulder 37 and expansion section 38.

Wall 35 and shoulder 37 are axially relative each other.

Body 25 also comprises:

Can rotate and the bar 26 be slidably received in along axle C in cavity 24 around axle C; And

Pin 27, it is fixed relative to axle C and is engaged in the groove 28 limited by bar 26.

In detail, bar 26 is towards the end axial end 31 be arranged on outside body 25 from the top axial end 30 of the wall 35 towards body 25, and it comprises;

-groove 28;

-expansion section 32;

-section 33, enclosed member 14 is matched with described section 33 prejudicially; And

-section 34, annex 22 is matched with described section 34.

The part 38 of wall 36 axially gets involved between shoulder 37 and wall 36, and holds the part 32 of bar 26.

Annex 22 and bar 26 move integratedly and comprise and hit surface 21, and when enclosed member 14 arrives midway location, this hits the container 2 that damage is hit on surface 21, make damage container 2 be easy to remove thus.

More precisely, the surface 21 of hitting of annex 22 is hit the so a kind of mode of container 2 (Fig. 9 and Figure 10) locate relative to enclosed member 14 to be made to hit when enclosed member 14 arrives midway location surperficial 21.

In the shown embodiment, it is bending for hitting surface 21.

Enclosed member 14 consists essentially of:

There is the circular slab 42 of axle D; And

Be matched with the arm 43 of the section 33 of bar 26.

In detail, arm 43 has the first end of the section 33 being matched with bar 26 and second end relative with first end, described second end limiting plate 42.

When enclosed member 14 is in stop position, the axle B of axle D and mouth 12 staggers (Figure 13).

When enclosed member 14 mediates, axle D is coaxial with the axle B of mouth 12, but enclosed member is axially separated with mouth 12.

When enclosed member 14 is in control position, axle D is coaxial with the axle B of mouth 12, and enclosed member 14 and mouth 12 Fluid Sealing contact (Figure 14).

Enclosed member 14 both rotated integratedly around axle C and bar 26, again along axle C and bar 26 translation integratedly.

Pin 27 stretches out along the axle E orthogonal with axle A, B and C, and is level in the illustrated embodiment.

Groove 28 is towards expansion section 32 from end 30, and it comprises (Figure 14):

Around the helix extending part 45 that axle C extends; And

The extending part 46 parallel with axle C.

See Figure 13 and Figure 14, actuator 15 can apply the application force guided by the axle C along bar 26.This application force---shape due to groove 28---makes bar 26 rotate translation and enclosed member 14 is moved along the first stroke, and makes bar 26 be parallel to axle C translation subsequently and enclosed member 14 is moved along the second stroke.

Therefore, when enclosed member 14 be configured in stop position (Figure 13) and bar 26 accept the application force parallel with axle C also upwards directed (see Figure 13) time, first bar 26 moves up along helical trajectory around axle C, and is parallel to axle C upwards translation subsequently.

On the contrary, when enclosed member 14 be configured in control position (Figure 14) and bar 26 accept the application force parallel with axle C also downwards directed (see Figure 14) time, first bar 26 moves down along helical trajectory around axle C, and is parallel to the downward translation of axle C subsequently.

Specifically, bar 26 and cavity 24 limit betwixt:

First variable volume chamber 29, it axially extends between the top 30 and the roof 35 of body 25 of bar 26; And

Second variodenser chamber 23, it is axially limited between the expansion section 32 of bar 26 and the shoulder 37 of body 25.

In the illustrated embodiment, actuator 15 is pneumatic.

More precisely, actuator 15 comprises (Figure 11-14):

Control unit 49;

Electricity valve 50;

Conduit 51 (being only schematically illustrated in Figure 11-14), it extends between electric valve 50 and chamber 29;

Electricity valve 52; And

Conduit 53 (being only schematically illustrated in Figure 11-14), it extends between electric valve 52 and chamber 23.

Specifically, the basis that control unit 49 damages the signal that container 2 exists in the expression that produced by sensor 20 controls electric valve 50,52, in conduit 51,53 is connected to pressurized air source and another in conduit 51,53 is connected to discharge side.

Specifically, the airflow direction of arrow instruction when conduit 51,53 is connected to pressurized air source or is connected to discharge side in conduit 51,53 in Figure 11 and Figure 14.

When conduit 51 (53) is connected to pressurized air source and conduit 53 (51) is connected to discharge side, the pressure in chamber 29 (23) is made to be greater than pressure in chamber 23 (29).So, bar 26 bears the power of downward (upwards) being parallel to axle C.

In the illustrated embodiment, control unit 49 and electric valve 50,52 are accommodated in body 17.

The operation of filling element 1 is with reference to only one filling 9 and describe with reference to corresponding container 2 and enclosed member 14.

Also illustrate the operation of filling element 1, be in stop position and the state of pin 27 and the tip contact of the extending part 45 of groove 28 (Figure 11 and Figure 13) from wherein enclosed member 14.

Driven rotatably around axle A by carousel 8 for filling 9, and received empty receptacle 2 at station I.

Specifically, container 2 is clamped by apparatus for fastening 16 and coaxial with the axle B of mouth 12.

Filling 9 along slave station I extend to station O path P carry out filling to container 2.

Along path P, valve 13 is arranged on open configuration, and in open configuration, it allows to pour into product and flow to container 2 by conduit 11 and mouth 12 from tank.

When sensor 20 detects that container 2 is not damaged, filling continuation, until arrive the given liquid height that can pour into product in container 2.

In this stage, valve 13 be arranged on closed configuration and filling 9 by filling good container 2 station O export the unshowned conveyer in downstream to.

When sensor 20 detects that container 2 is damaged, shown by detecting that container 2 cannot by the embodiment that suitably pressurizes before filling the container, enclosed member 14 is moved to midway location (arriving immediately after the position shown in Fig. 9 and Figure 10) from stop position and moves to final position (Fig. 7-8) from midway location subsequently by actuator 15.

As shown in Figure 9 and Figure 10, when enclosed member 14 arrives midway location, it hits the damage container 2 that clamped by apparatus for fastening 16 and causes and damages evicting from of container 2.

Therefore, container 2 is expelled out of along path P by filling 9.

In more detail, first enclosed member 14 moves to midway location along spiral first stroke upwards of axle C from stop position by actuator 15.At the end of this first stroke, the axle D of the enclosed member 14 and axle B of mouth 12 overlaps, but enclosed member 14 is still along axle B, D of overlapping and mouth 12 spaced apart (Fig. 9 and Figure 10).

Enclosed member 14 moves to control position along second stroke upwards parallel with axle B from midway location by actuator 15 subsequently, and enclosed member 14 Fluid Sealing contact mouth 12 time stop.

More precisely, in order to enclosed member 14 is moved to control position from stop position, control unit 49 controls electric valve 50,52, to make pressure in conduit 53 higher than the pressure (Figure 11 and Figure 13) in conduit 51.

As a result, make the pressure in chamber 23 higher than the pressure in chamber 29 and bar 26 is subject to the power upwards parallel with axle C.

From the state of Figure 13, the helix extending part 45 of groove 28 is engaged by pin 27.Therefore, the power upwards on bar 26 makes bar 26 rotate around axle C simultaneously and make bar 26 be parallel to axle C upwards translation.

Enclosed member 14 moves along the first stroke, when pin 27 is engaged in the extending part 46 of groove 28, and Mobile Termination.

When enclosed member 14 is in the end of the first stroke, annex 22 contacting container 2 also helps group to evict container 2 (Fig. 9 and Figure 10) from.

Then, the application force upwards on bar 26 merely causes moving up of bar 26, the described Mobile Termination when pin 27 is resisted against the lower end of the extending part 46 of groove 28, as shown in figure 14.

Therefore, enclosed member 14 moves along the second stroke, when enclosed member 14 Fluid Sealing contact mouth 12 time, described Mobile Termination.

Once enclosed member 14 arrives control position, control unit 49 controls electric valve 50,52, is greater than pressure (Figure 14) in conduit 53 to make the pressure in conduit 51.

As a result, the pressure in chamber 29 is made to be greater than the pressure in chamber 23 and bar 26 is subject to the downward power parallel with axle C.

Therefore, along the second stroke, by enclosed member 14, from control position to midway location, ground back moves actuator 15, and is back moved along the first stroke from midway location to stop position ground by enclosed member 14 subsequently.

Importantly will emphasize, the enclosed member 14 of filling 9 can move independent of other other enclosed member 14 of filling 9.

So, one or more damage container 2 does not affect the correctly filling of other not impaired container 2 along evicting from of path P.

Periodically, filling element 1 experiences cleaning step.

More precisely, tank by filling with cleaning agent, and the latter replace can pour into product at filling 9 internal circulation flow.

During cleaning step, valve 13 is arranged on corresponding open configuration, contacts and sterilize to whole conduit 11 and corresponding mouth 12 to enable cleaning agent.

In order to prevent cleaning agent from mouth 12 the spilling also environment of loss around filling element 1, all enclosed members 14 are moved to corresponding control position by all actuators 15 of all filling 9.

For the only situation that describes of enclosed member 14 during container filling 2 before enclosed member 14 is equal to from corresponding stop position to the movement of relevant work position, and difference is only not have container 2 to be arranged on the fact below mouth 12 during cleaning step.Therefore, enclosed member 14 and annex 22 do not hit the container 2 of any damage when they move to relevant work position together with during cleaning step.

At the end of cleaning step, enclosed member 14 is moved to corresponding stop position from relevant work position by actuator 15 simultaneously, with for during container filling 2, only the mode that describes of enclosed member 14 is identical before.

With reference to Figure 15 and Figure 16,9 ' the second embodiment indicating filling head.

Filling 9 ' is similar to filling 9, and only carries out open with regard to the difference of itself and the latter hereinafter; Any possible when, filling 9, the corresponding component of 9 ' or equivalent represent by identical Reference numeral.

Specifically, filling 9 ' is with the difference of filling 9, and actuator 15 ' can apply torque around axle C on bar 26 ' again can along axle C applying application force on bar 26 '.

Actuator 15' comprises:

Be fixed on one or more permanent magnets 60 ' of bar 26 '; And

Carried by body 25 and be magnetically couplable to the paired coil 61 ' of magnet 60 '.

Magnet 60 ' and coil 61 ' had not only produced the application force parallel with axle C but also the so a kind of mode produced around the torque of axle C is formed to make the magnetic pumping of coil 61 ' at magnet 60 ' upper (and therefore on bar 26 ').

Therefore, bar 26 ' is different from bar 26 because not comprising any groove 28.

The difference of the operation of filling 9 ' and the operation of filling 9 is, actuator 15 ' had not only applied torque around axle C but also the application force applied along axle C on bar 26 '.So, actuator 15 ' directly causes bar 26 ' (and therefore enclosed member 14) around the rotation of axle B and the translation along axle C.

From filling 9 that makes according to the present invention, 9 ' and the analysis of feature of packaging process, the advantage that it can obtain is obvious.

Specifically, actuator 15,15 ' by filling 9, and 9 ' carries.

Therefore, each filling 9, the enclosed member 14 of 9 ' can independent of all the other filling 9, and other enclosed member 14 of 9 ' moves, and it moves rule and all the other filling 9, and the mobile rule of other enclosed member 14 of 9 ' is different.

Because foregoing, filling 9,9' well more a lot of than the scheme flexibility described in the preamble of this specification sheets with regard to the movement of enclosed member 14.

In addition, no longer need high cost and heavy cam, at cleaning step and enclosed member 14, described cam only interacts that enclosed member 14 is moved to corresponding configuration.

In addition, the enclosed member 14 of filling 9,9 ' can be configured in control position, and all the other filling 9, the enclosed member 14 of 9 ' remains on corresponding stop position.

Therefore, in container 2 filling period with when damaging at container 2, can usefully use enclosed member 14 to hit the container 2 of damage and it to be evicted from from filling 9.

So, the container 2 of damage is expelled out of along path P and is not transported to the downstream of filling element 1.

Therefore, do not need to arrange in filling element 1 downstream in order to remove the special tool damaging container 2.

Control unit 49 and electric valve 50,52 are accommodated in body 17.

So, body 17 is for both the control unit 49 that holds closed cell 14 and electric valve 50,52.Therefore, filling 9,9 ' does not need to use cam or heavy external actuator with closed cell 14 mobile between stop position and control position.

Finally, obviously can to filling 9,9 ' and packaging process make multiple correction and modification and do not depart from the protection domain of claims.

Specifically, when the container 2 damaged must be expelled out of, actuator 15,15' can only be answered stroke along first-phase and move corresponding enclosed member 14 between corresponding stop position and midway location.

In addition, filling 9,9 ' can comprise actuator 15, and an only part of 15 ', especially only comprises body 25, bar 26 and chamber 23,29; Control unit 49, electric valve 50,52 and be positioned at filling 9,9 ' outside conduit 51,53.

In addition, sensor 20 can be different from the pressure sensor described in this specification sheets.
