A c tu a l In v e n t o r(s HAL L LA.I Y S .Address for Service: 44 ASHLEY STREET, HORNSBY N.S.W. 2077, AUSTRALIA In'venthn Title: PRT. FOR A HOSE FOR FILLING LIQUID INTO A CONTAINER Details of Associated Provisional Applications: Nos: P..

0 The following statement is a full description 'of this invention, Including the best method of performing it known to me:- I SUPPORT FO. A HOSE FOR FILLING LIQUID INTO A CONTAINER.

This invention is a hose support for use in a filling operation in which a container liner bag is filled with liquid.

It is common to transport and store up to 1000 liters of liquid in a plastic bag housed in a four s.ded rigid container. It is common for a container for the above purpose to be of a collapsible form comprised of four interlocking side panels with a first opposed pair or the panels anchored to a pallet and with the other pair of sides anchored to the first pair of sides. One such arrangement is known commercially as Pallecon (Trade Mark).

.In the above arrangement there has been a problem with the filling of the plastic bags in that the bag prior to filling (and during filling) can adopt a slumped condition in which folded over bag portions are formed. If the folds are allowed to remain in place as the bag is filled the folded configuration can become fixed due to the pressure exerted by the liquid in the bag. The result is a decrease in the volume to which the bag can expand with a resultant S* decrease in the volume of liquid that can be placed in the O bag. One method for overcoming this problem has been to inflate the bag with air prior to filling with liquid and to allow the air to escape as the bag is filled. This has not proved to be fully successful.

The \present invention provides a hose support which -2will ensure a liner bag for a container is maintained free of folds during filling, at least to the extent required for the bag to hold its designed volume of liquid.

Broadly, the invention provides a hose support including two parallel link arrangements each comprised of an upper link means and a lower link means in parallel spaced relationship to provide a link pair with the lenghts of the link means of each pair the same, a pivotal connection between respective first ends of the link arrangements, a pivotal connection between a second end of one link arrangement and a hose mount and a pivotal connection between a second end of the other link arrangement and a base member, the arrangement being such that as said hose mount is moved relative to said base between a lower travel limit and an upper travel limit the link means of each link pair will maintain a parallel relationship and the travel *ee :004 path of the hose mount will be a straight line in a 20 predetermined direction, an extension on said other .link arrangement with the extension extending beyond said second end thereof, a connection point on said extension and a connection point on said base, a hh tensioned resilient biassing means connecting said connection points to pivot said other link arrangement relative to said base to move said hose mount to its upper limit of travel, a releasable prop means with a 2afirst end connected to said base and a second end connected to said extension releasably to maintain said hose mount at its lower limit of travel.

A presently preferred form of the hose support of this invention will now be described with reference to the accompanying drawings in which: Fig.l is a perspective view of a first form of the hose support which is provided with wheels,

C

e• 3 Fig.2 is a schematic side view of the hose support of Fig.l attached to a bag in a container with the bag partially filled, Fig.3 is a view similar to Fig.2 where the bag is completely filled, Fig.4 is a schematic illustration of the geometry of the spring action for a first position of the hose support and is a view similar to Fig.4 for another position of the hose support.

10 The hose support of the invention is designed for use with a container 1 (see Figs.2 and 3) in which there is a o. liner bag 2 of plastic film material. There is a central :o nozzle 3 in the top face of the bag which is externally se threaded in order to be engaged by a coupling end 4 of a filling hose 5 which is connected to a supply means for liquid, e.g. a pump or a gravity tank.

The hose support includes parallel link arrangements 0 to indicated generally 6. The link arrangements include a pair of upper links 7 and a pair of upper links 8 pivotally connected at corresponding first ends at 9 and to one end of a tie link 16. The other ends of the links 7 are connected pivotally at 11 to a hose mount There are two lower links 12 and 13. The lower link 12 is connected pivotally at one end at 15 to the hose mount and at its other end to the tie link 16. The lower link 13 is connected pivotally at one end to the tie link 16 and at 4 its other end at 19 to a head member 26 on two legs 27 which end on a foot member 28. The foot member 28 is of generally form with two limbs 29 substantially at right angles to each other and a third limb 30. All of the limbs 29,30 are provided with wheels 31 whereby the hose support is able to be moved from place to place. As will be explained later the hose support need not be of the wheeled form.

The links 8 are connected at 17 to posts 18 upstanding 10 from the head 26 and extend therebeyond as indicated 38 and o\ ~are connected pivotally to one end of a part 21 an articulated tie bar with the other tie bar part 22 pivotally o connected to the head 26 at 35. The joint 23 connecting the tie bars parts 21-22 is of the overcentre locking type including a simple lug on one part which engages the other part when the tie bar is in the Fig.2 configuration thereby limiting the pivotal movement in the direction of the arrow A and preventing the hose support rising from the depressed condition illustrated in Fig.2. The arrangement allows free pivotal movement of the parts 21-22 in the opposite S direction to collapse the tie bar to the condition in which **fee: the two parts 21-22 in side by side relationship and overlying the head 26. The hose support would then be in the condition illustrated in Fig.3.

The hose support is biassed resilinAtly to the Fig.3 condition by tension springs 25 (having a predetermined 5 initial tension) with the springs connected at first ends to lugs 24 on the links 8 and connected at their other ends at 32 to a cross bar 33 on a downwardly extending leg 34 fixed to the head 26. The geometry of the spring attachment to the arm 8 is discussed later.

In a use sequence the bag nozzle 3 can be connected to the coupling end 4 of the hose 5 is one of several ways.

It can be connected as shown in Fig.2 where the hose support is lowered and locked in position by the tie bar 21-22 and the bag is then connected arranged as required in the b *container. Alternatively, a connection between the bag nozzle 3 and the hose coupling end 4 can be made when the hose support is in the raised condition and then the bag could be lowered into the container and the tie bar 21-22 can be locked to maintain the hose support in the depressed condition.

O*OO. At the commencement of a filling operation the hose support would be locked by the tie bar 21-22 in the Fig.2 condition. A small amount of liquid would be admitted to the bag to give it 'weight'. The tie bar 21-22 would be released. The bag nozzle will move upwardly in a straight line due to the parallel link arrangement and this is an important feature of the invention. Throughout the range of operation of the hose support the links 7 and 12 remain in parallel relationship and the links 8 and 13 also remain in parallel relationship. The result is a direct upward 6 force to the bag to draw folds out of the bag as it is filled and whilst the quantity of liquid in the bag is only exerting a small force on folds formed as the bag was placed in the container. Any volume reducing folds will be of a minor form and if not removed during the filling operation will not be detrimental to the volume of liquid that can be stored in the bag because of the designed excess volume of the bag to cater for such minor folds.

The construction of the hose support using parallel 10 acting links has a further advantage in tha- with a known device for the same purpose the bag nozzle is raised in a *geS curved path and there was an applied lateral force on the .bag nozzle. A lateral force can sometimes cause a leakage rupture where the bag nozzle is welded to the bag body, this problem is avoided with the arrangement of this invention.

With regard to the spring action during the filling

S

operation, there is a design increase in the pivoting force exerted on the hose support as the bag is filled. Referring see a to Fig.4, it will be seen that for the Fig.2 condition the spring tension line TL is spaced from the pivot point 17 by a lever arm LA1 and the pivoting force applied to the hose support is the product of the spring tension X the length of the lever arm. Fig.5 illustrates an advanced stage in the bag filling and it will be seen that the extension of the arm 8 to which the springs are attached has rotated and the lever arm LA2 is longer. Although there is a decrease in 7 the spring load because of the shortening of the distance between the connection points 24 and 35 this is compensated for several times by the increase in the length of the lever arm. As a result there is an increase in the pivoting force applied to the hose support as the bag is filled, which is a desirable condition.

Although the embodiment described has a base with wheels it is to be understood that the hose support can be mounted in any suitable manner by clamps or the like directly to the 10 container.

6 Soso Although the embodiment described includes an articulated tie bar or prop this is a preferred feature.

9 Other forms of prop could be used if desired.
