Definitions
- the present invention relates to a method of wrapping bales of fodder or silage. It also relates to a device for the implementation of such a method, as well as the balls obtained.
- fodder such as hay or silage is usually packaged in a press in the form of round or square bales, which are then wrapped. This wrapping allows the protection of materials by preventing the entry of air into the heart of the bales.
- Wrapping consists in applying a film or sheath, preferably stretched (e) on one or more adjacent bales, so as to obtain an anaerobic type of conservation of said bales.
- a film or sheath preferably stretched (e) on one or more adjacent bales, so as to obtain an anaerobic type of conservation of said bales.
- the film or the sheath prevents the penetration of air, in particular oxygen, into the heart of the bale, but also it removes all space between the film and the material, making it difficult for air to flow between them. Consequently, even if the film or the sheath has holes, it limits losses by preventing the propagation of air.
- the wrapping can be of the single ball type and this technique is currently the most developed. However, it does not make it possible to envisage large stocks insofar as on the one hand, it requires a quantity of film or significant sheath by bale and on the other hand, the production flow remains limited, the wrapping of bullets one by one slowing production.
- Another wrapping technique developed consists of wrapping several bales in succession. This technique reduces the amount of film used per bale and is also faster. This gives a better yield and a reduction in costs (less film used) while also allowing a reduction in plastic waste.
- bales when the bales are held for transport by means of a net, the latter can be improperly placed and therefore does not make the entire width of the bale and, when the bales are held by strings of tying which slightly compress the fodder, they form annular grooves at the periphery of the bale. Therefore, a film or sheath applied to these bales continuously cannot adequately cover the entire outer surface of the bale.
- tying strings hollow zones extend at least over three quarters of the periphery of a ball placed on the ground, these zones allowing the circulation of oxygen which could occasionally penetrate. rupture of the film seal, causing consequent losses. In addition, these areas between the ball and the film are also places of condensation which can also worsen the losses.
- the present invention therefore aims to reduce these drawbacks so as to improve the conservation of bales of fodder or silage continuously wrapped, in particular so as to offer them a conservation as good as that of bales wrapped individually.
- the subject of the invention is a process for continuously wrapping bales of fodder or silage having on their surface binding means such as nets, twines, or the like, characterized in that sections the means of tying bales during their wrapping.
- Continuous wrapping can be carried out either by spiral winding of a film, preferably stretched, around the bales one after the other or by entering the bales one behind the other in a sheath, preferably stretched, advantageously by passing through a part of the type of a funnel.
- the bale bonding means are preferably sectioned in a synchronized manner with the application of a film by spiral winding around said bales. It is also possible to section the binding means when the bales enter the sheath. This cutting of the binding means therefore takes place almost simultaneous with the application of film or sheath to the periphery of the balls.
- the bale therefore behaves as if it had a certain elasticity and tended to recover its original shape, that is to say before putting in place binding means, which eliminates the empty zones between the bale and the film or the sheath surrounding said ball.
- the density of a bale is not maintained by the force of the tying means but by its internal structure, the tying means being used only to transport the bales without risk and to maintain said bales in integrity during the storage period.
- the film or the sheath replaces the sectioned binding means: the film or the sheath, preferably stretched, and applied to the bales sufficiently maintains the integrity of the bales during their storage or transport.
- the present invention also relates to a device for continuously wrapping bales of silage or fodder having on their surface binding means such as nets, twines, and the like, characterized in that it comprises means cutting means for tying bales during their wrapping.
- the device can be of the type comprising means for winding a film in a spiral around the bales brought one behind the other, the cutting means being arranged to cut the means for binding the bales in synchronization with the application of the film to the periphery of said balls.
- the tying means are sectioned as and when the film is wound around the bales so that the integrity of the bales is maintained despite the cutting of the tying means by the almost simultaneous application of the film to the periphery of the bullets.
- the cutting means are positioned in said member. Therefore, the bales passing through the funnel undergo at the same time a sectioning of their binding means just before or during the application of the sheath at their periphery.
- the cutting means consist of a serrated knife positioned in the wrapping device so that the bale binding means are presented in front of the cutting means perpendicular to them to be sectioned and, preferably, the sectioning area of the tying means is located on the lower part of the bales to be wrapped.
- the passage of the cutting means leaves a groove which, located in the lower part of the bale, is advantageously crushed by the mass of the bale resting by said lower part on the ground and therefore does not constitute a preferential passage for the 'air.
- Bales continuously wrapped can be round bales but also square bales.
- round or square bales are introduced into the wrapping device, one behind the other so that the binding means are perpendicular to the cutting means.
- the device then preferably comprises two separate means of transport respectively bringing a row of square bales and, at the junction of the rows superimposed on each other, said device comprises at least one cutting means, preferably a means of double cut, to cut the means of tying the bale from above to the lower part of it and to cut the means of tying the bale from below to the upper part of it before or during the application of a sheath or a film on the periphery of the two rows of square bales.
- Figures 1 and 2 show a side view of a continuously wrapped bale in a conventional manner and a continuously wrapped bale according to the invention
- Figure 3 schematically shows a side view of an embodiment of a continuous wrapping device according to the invention.
- Figure 4 schematically shows a side view of another embodiment of a continuous wrapping device according to the invention
- a round bale 1 ′ has binding means such as twine 2, these forming grooves 3 on the surface of the bale 1
- binding means such as twine 2
- these grooves 3 form vacuum zones 5 between the periphery of the bale 1' and the sheath 4, these vacuum zones 5 favoring gas circulation along the periphery of the bale l 'if the sheath 4 has accidental perforations
- the sheath 4 is kept around the bale 1 until the place of use of said bale 1 where said sheath 4 can be removed and where the pieces of string 2 which had remained trapped between the bale 1 and the sheath 4 are also removed
- FIG 3 there is shown schematically a continuous wrapping device in which a film 7, preferably stretched, is tightened in a spiral around bales 1
- the bales 1 arrive on two carrying bars 8 parallel to the ground while a notched knife 6 extends in their path of passage towards the film 7 in the lower part of the bale 1
- the binding means 2 of the bales 1 arriving in the wrapping device extend perpendicular to the knife 6
- bale support and the tilt of the knife 6 are chosen so that the lower part of the bales 1 gradually comes into contact with the knife 6
- the bars 8 can deviate from one another, which allows the balls 1 to come gradually into contact with the knife 6 as they progress
- bale 1 is wrapped by the application of the film 7 which is wound in a tight spiral around the bale 1
- a bale 1 is obtained at the output identical to that described in the figure 2
- Figure 4 is shown a wrapping device in which introduces square bales 10 into a sheath 4.
- the square bales 10 are brought one behind the other so that their strings 2 extend perpendicular to the direction of advance (arrow a) of the bales 10. Two superimposed rows of bales 10 are introduced into the sheath
- a double knife 16 cuts the binding means 2 of the bale 10 from the top in the lower part thereof and the binding means 2 of the bale 10 from the bottom in the upper part thereof. so that the grooves left in the balls 10 are enclosed between the balls 10 and cannot be used for the circulation of gas.
- the binding means are cut just before or during the passage through a funnel-type member 12 distributing the sheath 4, preferably stretched, around the two stages of square bales 10.
- This funnel 12 can be used to stretch the sheath 4 to allow it to receive bales of dimensions greater than the dimensions of the unstretched sheath 4. The stretching of the film or of the sheath 4 facilitates their application to the surface of the bales.
- the invention makes it possible to obtain bales of fodder or silage which are distinguished from bales known in the state of the art, which comprise means of binding and are surrounded by a film or sheath, preferably stretched, by the fact that, the tying means having been cut, the bale, by its own elasticity, follows the film or the sheath without leaving substantially any empty areas between the bale and the film or sheath surrounding the latter.
