Definitions
- the present invention relates to the technical field of the production of ribbons of natural or synthetic fibers. More particularly, it relates to the manufacture of "bales" (bundles of fibers), for example following carding-combing of wool, containing one or more continuous ribbons of great length. In other words, the present invention relates to a device for packaging fibers forming continuous, heavy weight ribbons.
- the fiber treatment processes start with an operation called “preparation”, during which the fibers are forced to align with each other and which consists, using machines called “gills”, of assembling then to stretch ribbons of fibers coming from several “spools” (windings of fibers around a horizontal axis) and / or “pots” (windings of fibers whose overall shape is that of a cylinder having a vertical axial chimney) .
- bales contain from 10 to 48 coils or pots compressed according to their weight by means of a hydraulic press, then enclosed in a banded tarpaulin.
- said method consists firstly in feeding a large diameter pot using a gills specially designed for this purpose; once the pot is completed, it is sent to a press, also specially designed, comprising a funnel through which the contents of the pot are pushed, which opens into a container of cubic shape; then the content of a second jar identical to the first is introduced into the press in the same way; finally, the content of said cubic container, formed of two successive compressed ribbons, is packaged in a conventional manner. It can therefore be seen that the implementation of this method has the drawback of requiring a significant investment in equipment.
- the present invention relates to a process for manufacturing parallelepiped bales containing one or more ribbons of continuous fibers, said process allowing said continuous ribbons to have a high weight (for example, 200 kgp) while perfectly respecting the quality of the wick, and not requiring, for its implementation, gills or balers different from those already commonly used in the art.
- a gill is fed with several continuous ribbons, which are assembled and stretched to form a single ribbon.
- the latter comes out of the gills via a "paste", the function of which is to cause the ribbon to emerge from an orifice animated with a circular movement, this circle overhanging the pot and being inscribed in a horizontal plate called “plate to coil "; the center of this circle is located at a distance from the vertical axis of the pot approximately equal to the radius of said circle, this radius being approximately equal to half the radius of the pot.
- the pot turns on itself around its axis, so that the ribbon is deposited in the pot in epicycles. A dense material is thus obtained arranged around a central chimney of small diameter.
- the bottom of the pot is gradually lowered so as to keep the top of the contents of the pot. Constantly pressed against said plate to coil.
- the device according to the invention also comprises a conventional coiler which continuously drops a ribbon of fibers into a container, the bottom of which progressively lowers during filling.
- the container is of parallelepiped shape, and on the other hand, it is mounted on a mobile platform whose movements are arranged so that the ribbon falling into said container is deposited therein. forming successive staggered turns, which overlap and fill the container densely.
- said movable bottom is integral with a jack fixed on this movable platform and which exerts, during filling, an increasing upward force, so that the mass formed by said fibers, the upper face of which presses against the coiling plate, is subjected to constant pressure.
- the contents of the container are first transferred into the trunk of a baler, into which the contents of the container which has been filled are transferred later, one or more times. new in the same way; these successive ribbons are then compressed by means of said press, in order finally to obtain, after packaging, a bale containing ribbons of fibers of optimum wicking quality and which may each have a high weight.
- the device according to the invention makes use, as has been said, of a gills and a conventional baler.
- the apparatus used to implement the invention comprises two specific mechanisms, one serving for the horizontal movement of said mobile platform, and the other for the vertical movement of the bottom of said container.
- such mechanisms are known in themselves, and relatively inexpensive to produce.
- said mobile platform is driven in a translational movement along a rectangle traversed as many times as necessary until said container is full.
- the instantaneous speed of said mobile platform is synchronized with the speed of the coiler.
- FIG. 1 shows in vertical section a gills in the process of feeding a container according to the invention with tape by means of a coiler
- FIG. 2 is a top view of the apparatus represented in FIG. 1
- Figure 3 shows the mobile platform driving, according to the invention, said container during filling
- Figure 4 shows how the fiber ribbon is arranged in the container falling from the coiler.
- FIGS. 1 and 2 we see a fiber ribbon 1 passing through a gills 2 equipped with a coiler 4 to finish in a container 7 mounted on wheels 8.
- This gills 2 is entirely conventional, and, so known, the coiler plate 6 extends just above the container 7, which is naturally open at the top.
- the container 7 is however of characteristic design of the invention, as explained below; in particular, its height will preferably be greater than that of conventional pots, which requires the use of a sole 3 to raise the gills 2.
- the ribbon 1 emerges from the coiler 4 through an orifice which is moves along a circle 5 contained in the plane of the coiling plate 6.
- this fiber ribbon 1 is deposited in the container 7 on a movable plate 11 which gradually decreases during filling.
- This movable plate 11 (which for convenience of language we call “the bottom of the container") is integral with a jack 13 which exerts, during filling, an increasing upward force, so that the mass constituted by said fibers, the upper face of which presses against the coiling plate 6, is subjected to constant pressure.
- the container 7 Unlike conventional pots which are cylindrical, the container 7 according to the invention generally has the shape of a parallelepiped.
- co ⁇ ler plate 6 it is rectangular (unlike conventional co ⁇ ler plates, which are circular), and the container 7 moves during its filling under this plate 6 so that the plate 6, in view of above, permanently completely covers the container 7.
- FIG. 3 schematically illustrates this movement of the container 7, which is carried out using a mobile platform 12 comprising wheels 9 associated with rails 10. These wheels 9 are actuated by one or more motors (not shown) , for example servomotors, and / or hydraulic or pneumatic cylinders.
- motors not shown
- servomotors for example servomotors, and / or hydraulic or pneumatic cylinders.
- the cylinder 13 actuating the bottom 11 of the container 7 is integral with this mobile platform 12.
- the lower part of the cylinder 13 plunges into a pit 14 dug in the ground, this pit 14 s extending over a surface contained in the surface covered by the mobile platform 12.
- the container 7 thus repeatedly travels a certain trajectory until it is full.
- the effect of the combined movement of the mobile platform 12 and the coiler 4 is to arrange the ribbon 1 in the container 7 according to offset turns and arranged in superimposed layers, each of which resembles the partially filled layer illustrated in FIG. 4. It can be seen in this figure that the ribbon 1 fills the container 7 densely as it should.
- the content of container 7 can easily reach 200 kgp with current means.
- a preferred embodiment of the invention intended to optimize the regularity of the ribbon turns 1 which are deposited in the container 7, therefore consists in synchronizing automatically the instantaneous speed of the mobile platform 12 with the speed of the coiler 4, using sensors and an appropriate computer device.
- the bottom 11 is lowered below the container 7, the content of which is then maintained by means of lateral fingers 15 situated at the base of the container 7.
- the packaging of the fibers is then carried out in the following manner.
- the container 7 is first rolled up to the lower plate of a conventional baler (not shown). Said lower plate rises so that the content of the container 7 is lifted and introduced into the box of the baler.
- the ribbon 1 thus released from the container 7 is gripped laterally and kept in the air in said box, while the container 7 is brought back to the gills 2, and the lower plate of the press is lowered.
- a second container 7 possibly the same
- the upper plate of the baler is lowered in the direction of the lower plate and compresses the two ribbons one against the other.
