Definitions
- the present invention relates to the field of flexible packaging, in the form of plastic bags or sachets, and more particularly the automation of the closure of such packaging.
- At least one side face is provided at least in its upper part with at least one longitudinal element extending in a direction forming • an angle with the transverse axis, this longitudinal element being able to entangle in said upper strip of the packaging when a torsion is exerted on the upper end of the packaging, and being able to keep said upper part closed after such twisting.
- said longitudinal element is formed by a strip integrating a semi-rigid wire.
- said packaging consists of at least one bottom wall and at least one side wall having an opening.
- two opposite side walls each provided, at least in their upper part, with a semi-rigid wire.
- said longitudinal elements are arranged substantially parallel to the edges of the side walls.
- said longitudinal elements are integrated into a support advantageously made of flexible plastic material having a substantially flat and adhesive-coated face.
- the side walls and preferably also the bottom wall (10) are kept folded in accordion shape using a semi-rigid wire.
- the invention also relates to a system for packaging fluent materials comprising packages (1) according to at least one of the preceding claims and equipment for receiving and closing said packaging, characterized in that said equipment consists of a frame having an interior volume capable of receiving the package to be filled, and by means for exerting a twist on the upper strip of said package in order to ensure its closure after filling.
- the system comprises an item of equipment having a frame capable of keeping the upper part in the open position during the filling step, and capable of exerting a twist on this upper part at the time of closing.
- the frame is held in a case of shape identical to that of the frame, the lower and upper parts of which are open.
- the case consists of two movable parts around a hinge and a closure in the form of "clips" arranged on the part opposite to the hinge allowing the packaging to be immobilized within 1 ' case when closed.
- the case is provided with two prominent parts of substantially cylindrical shape on two of the opposite faces adjacent to that comprising the hinge allowing the case to slide in a support ensuring the rotation of said case as well as its opening .
- the invention also relates to a set of folded packages according to claim 1 and kept in their case, characterized in that the cases are stacked in a magazine provided with a lateral opening making it possible to push one case at a time under the device. filling of the packaging, the open faces being arranged at the upper and lower parts.
- the invention also relates to a device for filling and closing a package, characterized in that it comprises the means for gripping a case by the protruding parts and for placing the openings of said case under the filling device.
- the invention also relates to a device for closing a package, according to any one of claims 1 to 10, characterized in that the support of the case containing the package is driven by a rotary movement driving the side walls. of the packaging "thus causing the winding of said walls on themselves over at least one turn after filling the packaging.
- the invention finally relates to a method for automatically filling a package, according to the invention, characterized in that a package is positioned under a weir and in that also a container advantageously made from welded wire, rigid, under said packaging, intended to receive said packaging during its filling and to maintain the walls of said packaging once said packaging (1) is filled.
- FIG. 1 represents a schematic view of the packaging
- FIG. 2 represents a sectional view vertical filling equipment associated with such packaging
- Figure 3 shows a top view of such equipment.
- the packages are constituted, as shown in Figure 1, by a bag having side walls (3, 4, 5, 6) and a bottom (7), and forming a substantially rectangular receptacle in the open position.
- Two opposite side walls (3, 5) are provided at their upper part (8) with a longitudinal element (20) forming an angle with respect to the transverse direction (by transverse direction is meant a direction parallel to the plane of the opening ).
- This longitudinal element is semi-rigid and preferably non-elastic. Its function is to "twist” in the upper part when it is “ subjected to " a twisting movement, and to " keep in the twisted position this upper part to prevent it from opening again , when we stop exercising said twist.
- the additional equipment shown in Figures 2 and 3 is formed by a case (22) whose section corresponds substantially to the section of the package in the open position.
- the height can be substantially identical to that of the bag.
- This equipment further comprises a rectangular frame (21) making it possible to hold the upper part of the bag by winding the metal part around the structure of the frame.
- the case (22) is open at its upper and lower parts and closes on the frame (and therefore on the upper part of the bag) making it possible to fold the bag in accordion.
- the metal wires keep the packaging in this folded position inside the volume of the case.
- This case has on two sides a system of slides and gripping (semi-cylindrical shape)
- a vertical magazine containing a number of cases and having two openings at the bottom on two opposite sides, the exact dimensions of one case
- the equipment also includes a feed hopper comprising:
- the function of this device is to: cause the upper part of the bag to rotate
- a parallelepipedic mesh container the size of the bag, mobile on a rolling train which is placed under the hopper.
- a device feeds a semi-fluid material into a hopper, the butterfly valve opens progressively when a case provided with a bag is pushed into its housing (case holder)
- the material flowing in the bag causes the deployment of said bag which gradually will occupy the volume of the container.
