The specific embodiment

As shown in Figure 1, and the supposition only do not mean that restriction for the purpose of simplifying the description, vertical axis Z-Z overlaps with the rotation axis of filling machine.Filling machine is formed by the first top ring 100 and bottom ring 300 basically, and the described first top ring 100 has applying nozzle 110, and described bottom ring 300 has the supporting member 310 for container to be filled 1; Described two ring axial restraints and rotation synchronously make that nozzle 110 and container 1 are coaxial all the time at vertical direction Z-Z.

Washing equipment according to the present invention is axial arranged between two

rings

100 and 300, and ring 200 in the middle of comprising, described in the middle of ring 200 have along its circumference, inner hollow and the cup 210 that radially extends, described cup has upper shed 210a.

Described cup 210 has the pipeline 211 that is formed in its side surface, described pipeline 211 is connected to annular and discharges collector 220, this annular discharges collector 220 and is provided with fixing releasing tube joint 221, and this fixing releasing tube joint 221 becomes integral body with bottom ring 300.

The lip ring 212 of O shape lopps type also is located at the inside of cup 210.

The number of cup 210 is arranged to corresponding with the number of applying nozzle 110, and arranges with certain angular distance at certain position, for example, and with the coaxial but mis-aligned of described nozzle.

Middle ring 200 has the cylinder 260 that becomes one with it, described cylinder 260 has can cause that ring 200 rotates to mechanical brake 260a and the arm 261 of control position from dead position (Fig. 2), wherein in each cup of control position and corresponding nozzle 210 coaxial arrangement (Fig. 4).

Ring 200 was moved at both direction along vertical axis Z-Z in the middle of running gear 250 was used for making, and running gear 250 also is arranged between bottom ring 300 and the middle ring 200.

Use above-mentioned configuration and with reference to figure 5, describe flush sequence now:

-during filling containers 1 (Fig. 5 a), nozzle 110 and container 1 coaxial arrangement, and cup 210 is setovered at a certain angle with respect to described nozzle 110 and is in raised position;

-finish when filling, flush sequence starts from the operation of running gear 250, running gear 250 make ring 200 vertically Z-Z be reduced to the position (Fig. 5 b) that they and nozzle 110 do not interfere;

-operation cylinder 260, cylinder 260 causes the rotation of ring 200, takes each cup 210 to the position coaxial with corresponding nozzle 110;

-operational movement device 250, described running gear 250 rise ring 200, engage with nozzle 110 up to cup 210, and O shape ring 212 distortion simultaneously are in order to form the connection of sealing;

The flushing liquid supply of-pressurization, described flushing liquid along pipeline by and pass applying nozzle, and it is finished cleaning, described flushing liquid is collected by cup 210 under the situation of not overflowing, be transported to annular by pipeline 211 and discharge collector 220, and being transported to the release outlet from here, this process describes in detail hereinafter;

-to end when flush cycle, described order repeats conversely, makes machine reset into operating conditions when filling the circulation beginning.

Shown in Fig. 6 a-6b, can imagine, to be conveyed leave in case the collection of the flushing liquid that discharges by forcing release gear 400 to be carried out, the described release gear 400 that forces comprises pump 401, described pump 401 is arranged on the sliding part 420, described pump 401 can freely be advanced on sliding part 420, and arm 430 vertically Z-Z extends, arm 430 is provided with the roller 431 that can vertically engage with centering Y-piece 330, described centering Y-piece 330 is in aggregates in a certain position and bottom ring 300, and (Fig. 6 a) thereby cause the oral area 410 of pump 401 and the relative coaxial positioning of the end fittings 221 of annular release collector 220; In case finish centering, device 430 rises make and being sealedly engaged of oral area 410 and adaptor union 221 begin to discharge flushing liquid simultaneously.

Therefore, it is evident that, use is according to equipment of the present invention, can be at the quick pressure flush that does not have under the situation of overflow to realize to (especially in the vessel filling machine) all product supply means spares, and known how such equipment can merge in the filling machine itself and not normal with it working cycle interferes.

Be understandable that in addition for special flush cycle, described equipment also can be brought into play function with the fluid of supply in opposite direction.

Though some versions and some preferred embodiments at the embodiment of the invention are described, and are understandable that, protection scope of the present invention only limits by following claim.
