TECHNICAL FIELD OF THE INVENTION

The present invention relates to the field of collection and packaging of articles.

[002] The invention relates more particularly to equipment for collecting and packaging articles in a bag made from a sheath formed of two plastic films superposed and assembled together on their lateral edges, said equipment comprising a container body comprising an opening for the passage of articles and a space for receiving at least one bag made from the sheath, located under the opening for the passage of articles.

[003] By articles, we mean any type of product that can be collected in bulk or individually. These may be products intended to be used, such as food products (sweets, starches, cakes, etc.) or non-food products (cosmetics, batteries, etc.) or used products to be thrown away.

[004] A preferred but not exclusive application of the collection equipment according to the invention is the collection of waste.

STATE OF THE ART

[005] In the particular case of waste collection, application WO200400694 discloses a waste collection device comprising a container in which a plastic trash bag is placed comprising a storage compartment for an envelope in the form sheath made of a plastic film and intended to constitute a bag, said envelope being contained in the storage compartment in folded form, said storage compartment being arranged so as to define an upper central orifice of said container through which waste can be introduced in said bag, drive means for unwinding the envelope from the storage compartment towards the bottom of the container, said drive means being capable of adopting a release position in which they delimit an opening in the upper edge of the envelope allowing the introduction of waste without contact with the open upper edge of said envelope, and means for sealing and cutting the envelope making it possible to produce a bag from said envelope coming out of said compartment, then to close and separate from the rest of said envelope, the bag once the latter has been filled with waste.

[006] However, this collection device has the disadvantage of requiring relatively difficult manual handling of the envelope by an operator for its placement in the storage compartment. Furthermore, it does not allow replenishment of the envelope at any time, regardless of the state of filling of the envelope, the bag being made only once the envelope is filled with waste.

[007] The invention aims to remedy these problems by proposing collection equipment allowing a simple, easy and quick installation of a plastic sheath intended for the collection of waste, but also of any article that can be collected in bulk. or the unit, by limiting the manual intervention of an operator, and the realization of a bag from this sheath automatically.

[008] The invention also aims to provide equipment allowing simple and practical restocking of collection bags, independently of a collection in progress.

[009] The invention also aims to provide collection and packaging equipment allowing optimal collection of articles in bags by limiting the risks of dismantling the bags from their support.

DETAILED DESCRIPTION OF THE INVENTION

In relation to Figures 1 to 9, there is described an embodiment of waste collection equipment 1 in a bag 50 made from a roll of sheath 5 formed of two superposed plastic films and joined together on their side edges. Advantageously, the sheath is made from materials comprising vegetable starch and recycled plastic.

[0021] Figure 1 shows in particular an external perspective view of the collection equipment 1 according to an embodiment, while Figures 2 to 9 show the internal frame 10 of the collection equipment.

In the embodiment illustrated in Figure 1, the collection equipment 1 comprises a container body 2, of substantially parallelepipedic general shape, provided with a door 3 allowing access to the interior thereof. this. In the example, the door 3 extends over the height of the container body and defines the front face 21 thereof. The container body 2 is advantageously dimensioned to define an interior space 20 making it possible to contain several bags filled with waste. It is of course obvious that the dimensioning of the container body 2 will be adapted according to the place and/or the type of waste intended to be collected.

The collection equipment 1 further comprises an opening for the passage of waste within it. In the example shown, the opening is formed in the upper part, on one of the side faces, in this case the front face 21 forming the door. The invention is of course not limited to this configuration, it being possible in particular for the waste passage opening to be formed on the upper face of the container body 2. Advantageously, the waste passage opening is closed off by a folding flap 22.

The interior space 20 of the container body 2 comprises an internal frame 10 which supports a reel-drum 4 intended to receive the roll of sheath 5, means for causing the unwinding of the sheath 5 over a predetermined height from the reel-drum 4 towards the bottom of the container body 2 and means for gripping the sheath 5. According to the invention, the gripping means of the sheath 5, shown in detail in Figure 7, comprise drive rollers 8A, 8B, 9A, 9B arranged in pairs 8, 9. Each pair 8, 9 of rollers is arranged to drive and maintain in engagement one of the films of the sheath 5. To do this, the rollers 8A, 8B, 9A, 9B of each pair 8, 9 are arranged parallel to each other and in contact with each other. one from the other advantageously over their entire length. At least one of the rollers 8A, 8B, 9A, 9B of each pair is rotatable around its longitudinal axis. Advantageously, the rollers 8A, 8B, 9A, 9B of each pair are rotatable around their longitudinal axis, at least one of the rollers being motorized. In the illustrated embodiment, the equipment comprises two pairs 8, 9 of rollers, one of the pairs remaining fixed relative to the internal frame 10, the other pair being movable between a folded position in which the rollers 9A, 9B of the mobile pair 9 come into contact with the rollers 8A, 8B of the fixed pair 8 and a position in which the rollers 9A, 9B of the mobile pair 9 are separated from the rollers 8A, 8B of the fixed pair 8.

[0026] In the example shown, which is not limiting, the frame comprises two side frames parallel to each other, arranged opposite each other and connected to each other by spacers. The rollers 8A, 8B of the fixed pair 8 are mounted on fixed spacers connecting the two side frames of the internal frame 10 while the rollers 9A, 9B of the mobile pair 9 are carried by a tilting arm (in the example illustrated, the arm is in the form of a tilting frame). The rollers 8A, 8B, 9A, 9B of each pair are mounted transversely on the frame and extend parallel to the front face 21 of the container body 2. As illustrated in FIG. 7, the pairs 8, 9 of rollers, when the tilting frame 14 is in the folded position, are staggered relative to each other, the rollers 9A, 9B of the mobile pair 9 being in contact with a roller 8A, 8B of the fixed pair 8.

The drive rollers 8A, 8B, 9A, 9B are arranged under the drive means of the unwinding 7 of the sheath 5 and arranged with the latter so that the sheath 5 unwinds between the pairs of rollers. In order to ensure that each of the films is picked up by the pair of rollers directly in contact with the film concerned, the rotary rollers of each pair are rotatable in opposite directions.

The drum-reel 4, located, in the example shown, in the vicinity of the rear face of the container body (opposite face to the door), has a transverse fixed receiving axis extending parallel to the front face 21 of container body 2. As illustrated in Figures 8 and 9, the drive means of the unwinding of the sheath 5 comprise two drive rollers 6, 7 rotatable about their longitudinal axis. In the example illustrated, the drive rollers 6, 7 extend parallel to the axis of the reel-drum 4. One of the drive rollers 6 is mounted on a motorized axle connecting the two side frames of the chassis. The other roller 7 is rotatably mounted on a movable rod which can slide from a so-called release position in which the drive roller is separated from the motorized roller and a so-called service position in which the roller is placed contiguous (this is i.e. attached longitudinally) to the motorized roller. As illustrated in Figure 8, the sheath 5 is intended to pass between the two drive rollers 6, 7. As will be seen later, the release position of the mobile roller 7 makes it possible to position the sheath 5 between the rollers of training and the service position makes it possible to engage the sheath 5 between the and to drive the sheath 5 towards the bottom of the container by actuating the rollers 6, 7.

[0030] In order to produce the bag 50 from the roll of sheath 5 placed on the reel drum 4, the waste collection equipment 1 comprises means for heat-sealing the sheath 5 located below the means for holding the the sheath 5 and arranged to seal the sheath 5 transversely. The sealing means are activated when the tilting frame 14 is in the closed position and when the presence of the sheath 5 at the level of the sealing means is detected.

[0031] Similarly, the collection equipment 1 comprises means for transverse cutting of the sheath 5. The cutting means are located between the drive means 6, 7 and the gripping means of the sheath 5.

In the illustrated embodiment, the container body 2 is equipped, on its inner wall, with blowing means 11 arranged to blow air in a direction substantially parallel to the longitudinal axes of the drive rollers 8A, 8B, 9A, 9B sheath gripping means.

In the embodiment described, the blowing means comprise finned devices fixed to the inner side walls of the container body 2 of which only the supports, designated by the reference 11, have been shown in the figures. Other means or arrangements allowing the blowing of air can of course be provided without departing from the scope of the invention. [0034] The blowing means are arranged on each wall facing each other so as to make it possible to generate a blast of air in the direction of the upper part of the bag 50, and more particularly at the level of the edge free outer bag (that is to say the edge of the bag which is not engaged with the drive rollers 8A, 8B, 9A, 9B). The blowing means are intended to be actuated during passage from the separated position of the rocker arm to its folded position. Thus, when tilting the tilting arm 14 to close the bag 50 held in engagement by the drive rollers 8A, 8B, 9A, 9B, a blast of air is generated by the blowing means and directed onto the free edge of the bag which then engages inside the bag. Advantageously, the blowing means are arranged so as to maintain the free edge in a substantially horizontal plane. This thus makes it possible to ensure complete closing and sealing of the bag.

The invention is described in the foregoing by way of example. It is understood that the person skilled in the art is able to carry out different variant embodiments of the invention without departing from the scope of the invention, whether it is a question of collecting waste or collecting articles other than garbage.
