This application is a National Phase of PCT Patent Application No. PCT/ES2020/070118 having International filing date of Feb. 19, 2020, which claims the benefit of priority of Spain Patent Application No. P201930168 filed on Feb. 26, 2019. The contents of the above applications are all incorporated by reference as if fully set forth herein in their entirety.
The object of the present patent application is to provide a device for emptying flexible bags containing fluids which incorporates notable innovations and advantages over the techniques used hitherto.
More specifically, the invention proposes the development of a device for emptying flexible bags containing fluids, which, due to its particular arrangement, allows the outlet of the fluid trapped between the folds of the flexible material of the bag and the same fluid to be carried towards the outlet of the bag, in a simple, quick and effective manner.
Nowadays flexible packages or bags for fluid products called bag in box are known.
These types of bags normally house fluid products of various natures, such as cosmetics, foodstuffs, pharmaceuticals, amongst many others.
It is for this reason that due to the different properties that each one of these fluid products has, it is sometimes complicated to empty the contents of its bags satisfactorily in order to use the entire amount of product since, in some cases, disposing of a quantity which could be considered a minimum amount of product can mean a substantial economic loss, all due to the elevated cost/kg to which these products may rise.
As a result, for years, a multitude of systems have been provided to satisfactorily empty these types of bags, attempting to minimize the amount of product that is disposed of due to not being satisfactorily emptied from the interior of the flexible bag made of polymer material preferably.
There are many systems that produce the favorable discharge of these types of fluid products which have different elements that interact with the container bag to cause the emptying of its contents towards the discharge mouth that they usually have.
There are some systems that are especially complex and which incorporate electric, pneumatic or hydraulic operating elements which substantially complicate the entire operation of the system and the costs inherent to its implementation, maintenance and other operations.
The present invention contributes to solving and resolving the present problem as it allows the outlet of the fluid trapped between the folds of the flexible material of a bag and the same fluid to be carried towards the outlet of the bag in a simple, quick and effective manner.
The present invention has been developed with the aim of providing an emptying device for flexible bags containing fluids which is essentially characterized in that it comprises traction means and draining means, the draining means being physically connected to the traction means by means of positioning means such that they are rotatably moveable around the traction means, and the traction means and the draining means being arranged and mutually enabled for stretching a flexible bag from the traction means and simultaneously passing and circulating the bag through the draining means.
The distance between the traction means and the draining means is preferably variable in the device for emptying flexible bags containing fluids.

Other features and advantages of the device for emptying flexible bags containing fluids will be evident from the description of a preferred, but non-exclusive embodiment which is illustrated by way of non-limiting example in the accompanying drawings, in which:
The device for emptying flexible bags containing fluids of the proposed invention comprises traction means and draining means
As is shown schematically from different perspectives in one preferred embodiment represented schematically in
In addition, in this same preferred embodiment of the same
The winch 1 is connected to a container 5 by means of a structure 51 or frame which is fixed in the container 5 itself, the bag 2 initially being arranged in the interior of said container 5.
In
As can be seen schematically in
The winch 1 in its rotary movement tractions and stretches the bag 2 which is wound around the same winch 1, as can be seen in
At the same time, as the bag 2 is being wound around the winch 1, the same bag 2 is passed and circulated tightly between the rotary rollers 3, as is indicated by the arrows in the same
The rollers 3 are physically connected to the winch 1 by means of positioning means such that they are movable in their position with respect to the winch 1, having a rotary movement around the winch 1, as is indicated by the rotary arrows of the
To this end, in this preferred embodiment, the positioning means comprise a bar 6 of a telescopic nature, connected by means of a joint 61 at one of its ends and in the structure 51 to the winch 1, and connected at its other end to the rollers 3. With the rotary movement of the bar 6 around the joint 61, the rotary movement of the rollers 3 is therefore achieved, and the telescopic nature of the same bar 6 allows its radius of rotation and therefore the distance between the rollers 3 and the winch 1 to be varied, and thus to adapt to the different dimensions which the container 5 may present, which container is responsible for supporting the bag 2 which is intended to be emptied conveniently by means of the device for emptying flexible bags containing fluids of the invention.
In addition, as the bag 2 is being wound on the winch 1, the bar 6 by means of the joint 61 tends to be arranged in a vertical position, as there is less section of the bag 2 below the rollers 3. To this end, there is a limit sensor 7 connected to the motor 11, which detects the vertical position of the bar 6 which indicates that the bag 2 is already wound on the winch 1. In this situation, the sensor 7 stops the motor 11. This arrangement allows the operating process of the device for emptying flexible bags containing fluids of the invention to develop automatically without the presence of an operator once the flexible bag 2 is connected to the winch 1.

The device for emptying flexible bags containing fluids of the invention can be adapted to different sizes and volumes of the bag 2 and containers 5.
Owing to the device for emptying flexible bags containing fluids of the proposed invention, the outlet of the fluid trapped between the folds of the flexible material of the bag 2 can be carried out and the same fluid carried to the outlet of the bag 2 in a simple, quick and effective manner and regardless of the geometry of the bottom of the container 5 or recipient housing the flexible bag 2.
In another preferred embodiment of the same device for emptying flexible bags containing fluids of the proposed invention, the referenced structure 51 or frame incorporates horizontal displacement means for displacement along the same ground where the container 5 is located, means for regulating its height in relation to the same ground and means for regulating its horizontal width in relation to the same container 5.
This means that said structure 51 can therefore be adapted to different proportions which a container 5 may have, that is to say, to its height and/or amplitude or width, in addition to facilitating its horizontal transfer to carry out its service on successive containers 5.
As can be seen schematically in
Said legs 10 are of a telescopic nature and the regulation of their useful length allows the structure 51 to have a variable height, as indicated by the arrows of

Similarly, as can be seen schematically in
In addition, the horizontal width regulating means comprise crossbeams 14 of a telescopic nature and in a horizontal arrangement which are connected to the legs 10 and the structure 51 itself, as can be seen in
The regulation of the useful length of the crossbeams 14 allows the device for emptying flexible bags containing fluids of the invention to have a variable useful working amplitude or width as indicated by the horizontal arrows of
In accordance with the above, the crossbeams 14 are simultaneously connected to the legs 10 and to the structure 51 itself such that the legs 10, the crossbeams 14 and the structure 51 itself configure an assembly of cubic geometry and variable volume and therefore capable of being adapted to contain any proportions of a container 5, as can be seen especially in
In addition, the structure 51 incorporates lateral protection means, enabled to be arranged on the periphery of the container 5. In this preferred embodiment, the lateral protection means comprise flat plates 15 enabled to be positioned vertically on any of the sides of the container 5, as can be seen in
Similarly, the structure 51 incorporates fixing means, enabled to reversibly secure and retain the structure 51 in one position in the container 5, and therefore to allow the device for emptying flexible bags containing fluid of the invention to function and be removed from the same container 5 after its operation.
In this preferred embodiment, the fixing means comprise elements for blocking or braking the wheels 13, other elements for blocking the extension of the telescopic legs 10 and other elements for blocking the extension of the telescopic crossbeams 14, known in the prior art and not represented in the drawings, in which by means of a simple manual operation, its blocking or release is achieved.
