    专利说明:

    The invention relates to a dough forming machine which has an endless belt which can be circulated around at least one cylinder to move the dough pieces. This machine comprises a strip of a soft or flexible fabric with a first end which is held at a level above the cylinder and with a second end, opposite the first, which preferably extends at a level below the cylinder. cylinder so that the fabric extends opposite the cylinder and surrounds the cylinder over part of its circumference. This band allows the passage of a dough between the canvas and the endless belt facing the cylinder.
    The machine according to the invention relates in particular to a moulder for shaping dough pieces to give them the shape of baguettes or elongated loaves. This machine is, for example, used in bakeries for the manufacture of long breads or flutes.
    Moulders, according to the prior art, have a relatively complex construction and occupy a space which is relatively large. In addition, the known machines have the disadvantage that the dough is often stretched too much during shaping, which adversely affects the quality of the dough. Such moulders are, for example, described in documents FR 1118856, FR 2806257 or WO 02/074091.
    NL 7600676 describes a moulder with an endless belt inclined at an angle greater than 45 ° from the horizontal. The dough pieces are shaped during their upward movement between this endless belt and a rigid wall. Thus, the dough is stretched too much during shaping during this upward movement.
    The invention aims to remedy these drawbacks and to provide a moulder for, for example, baguettes which is very compact, which uses a very simple technique for shaping the dough pieces and which prevents the dough from being stretched too much.
    For this purpose, the aforementioned strip is suspended freely at its first end and the strip has a reserve of canvas at the location of the second end. Thus, when no dough is present between the canvas and the cylinder, the canvas rests against the endless belt at the location of the cylinder and when a dough piece is carried on the endless belt, the canvas moves away from the cylinder as the dough passes between the cylinder and the fabric while maintaining contact between the fabric and the dough.
    Advantageously, the part of the strip which extends between the first end and the cylinder is kept taut by the action of the belt circulating on the web of the strip during contact between the strip and the belt.
    According to an interesting embodiment of the machine, according to the invention, the position of the first end of the strip is movable relative to the cylinder in order to adjust the pressure force exerted by the strip on the dough piece when the latter moves. between the mat and the tape.
    According to a particular embodiment of the invention, said reserve is formed by a part of the web of the strip which is folded back on itself at the location of the second end below the level of the cylinder.
    Interestingly, drive means are provided to move the upper surface of the endless belt towards said belt.
    The invention also relates to a method for forming dough pieces in which a dough piece is carried by an endless belt circulating around at least one cylinder. The dough piece is thus moved towards a strip of a flexible canvas, a first end of which is held above the endless belt and a second end of which is preferably present below the level of said belt.
    This method is characterized in that said strip bears against the endless belt at the location of said cylinder, when there is no dough present between the strip and the belt, to keep the strip stretched between said first end. and the belt by the presence of friction between the circulating belt and the strip. When the dough piece comes into contact with the strip, during its movement by the belt, the dough piece is subjected to a rotation about an axis transverse to the direction of movement of the dough piece following the friction between the dough piece and the canvas. the strip, this strip moving away from the cylinder as the dough passes between the cylinder and the fabric while contact is maintained between the fabric and the dough. During this passage of the dough between the cylinder and the strip, the strip is supplied from a reserve of canvas located below the endless belt or below the cylinder.
    Other details and particularities of the invention will emerge from the description given below, by way of nonlimiting example, of some particular embodiments of the machine and of the method, according to the invention, with reference to the accompanying drawings. .
    Figure 1 is a schematic side view of an endless belt which carries a dough to be formed to a flexible strip, according to the invention, after the dough has been placed on the carpet.
    FIG. 2 is a view similar to that of FIG. 1 when the dough piece comes into contact with the flexible strip.
    FIG. 3 is a view similar to those of FIGS. 1 and 2 when the dough piece is below the endless belt and in contact with the flexible strip.
    FIG. 4 is a view similar to those of the preceding figures in which the shaped dough piece is on the receiving table.
    In the various figures, the same reference numbers relate to similar or identical elements.
    The invention relates in general to a machine for shaping dough pieces in order to form baguettes or long loaves.
    Figures 1 to 4 show schematically a side view of an endless belt 1 running from this machine on which dough pieces 2 are placed one after the other. The endless belt 1 can circulate around two parallel cylinders 3 and
    4. Drive means are provided allowing the belt 1 to circulate as indicated by arrows 5.
    Thus, a dough piece 2 which is placed on the upper surface of the carpet 1 is moved in the direction of the arrow 5 towards a strip 6 which consists of a flexible canvas. The upper surface of the belt 1, in particular upstream of the cylinder 3, preferably extends substantially horizontally. The strip 6 has a first end 7 which is held at a level above the cylinder 3, in particular, above the level of the endless belt 1. The first end 7 is held at a fixed position during the shaping of the dough pieces. .
    This first end 7 is fixed to a rod 8 which extends substantially parallel to the cylinders 3 and 4. The ends of the rod 8 are suspended in corresponding recesses 9 provided in a support 10 for this purpose. This support 10 has a succession of recesses 9 at different positions to allow the first end 7 of the strip 6 to be moved and put in different positions relative to the cylinder 3.
    A second end 11 of the belt 6, opposite the first end 7, extends at a level below the cylinder 3, in particular below the endless belt 1, so that the web of the belt 6 extends facing this cylinder 3. It is, in particular, ensured that the strip 6 is suspended freely at its first end 7 and this such that the strip surrounds the cylinder 3 over part of its circumference.
    A reserve 12 of canvas of the strip 6 is present at the location of the second end 11 below the belt 1. In the embodiment of the invention, shown in the drawings, this reserve is formed by a part of the canvas which is folded back on itself.
    When no dough is present between the strip 6 and the cylinder 3, which is opposite this strip 6, the fabric of the strip 6 rests against the belt 1 at the location of this cylinder 3 on a part of the circumference of the latter and the band 6 therefore bears against the endless belt 1. Following the movement of the belt 1 in the direction of the arrow 5, the band 6 is kept stretched between its first end 7 and the belt 1. Indeed, by the presence of friction between the circulating belt 1 and the strip 6, a tensile force is exerted on the strip 6. When a surplus of fabric from the strip 6 is present above the belt 1, this surplus is moved to the reserve 12 below the belt 1 by the action of the belt 1 on the strip 6 as shown schematically by the arrow 13 in Figures 1 and 4.
    To shape a dough piece 2, it is placed on the upper surface of the endless belt 1 as shown in figure 1. The dough piece 2 is then carried by the belt 1 towards the belt 6 at the location of the cylinder 3 on which carpet 1 is circulating. When the dough piece 2 comes into contact with the strip 6, the dough piece 2 is subjected to a rotation about a transverse axis with respect to the direction of movement of the dough piece following the friction between the dough piece 2 and the fabric of the strip 6 during that this strip exerts a pressing force on the dough piece 1.
    The dough piece therefore moves along the periphery of the cylinder 3 while rolling between the circulating belt 1 and the strip 6. The strip 6 moves away from the cylinder 3 as the dough piece 2 passes between the cylinder and the strip. canvas while the dough is held between the carpet and the web of the strip 6.
    Following the passage of the dough piece 2 between the strip 6 and the cylinder 3, the strip is fed automatically from the reserve 12 located below the belt 1 in order to allow the strip 6 to move away from the belt 1 or from the cylinder 3 to where the dough is. The feeding of the strip 6 from the reserve 12 is shown schematically by the arrow 14 shown in Figures 2 and 3.
    As already mentioned above, the position of the first end 7 of the strip 6 is movable relative to the cylinder 3. This makes it possible to adjust the pressure force which is exerted by the strip 6 on the dough piece when the latter moves. between belt 1 and belt 6.
    To adjust this pressure force, which is exerted on the dough pieces 2 during their shaping between the circulating belt 1 and said strip 6, the angle between the strip 6 and the upper surface of the belt is adjusted. In particular, this pressing force increases as the aforesaid angle decreases. Thus, the pressure force is adjusted by modifying this angle by moving the first end 7 of the strip 6. To move the first end 7, the rod 8 is placed in the appropriate recess 9 of the support 10.
    At the end of the shaping of the dough piece 2, the latter leaves the passage between the strip 6 and the belt 1 below the belt 1 and the dough piece is then moved on a receiving table 15. The passage for the dough pieces 2 between the strip 6 and carpet 1 leads to this reception table 15.
    Preferably, said second end 11 of the strip 6 is fixed at a level below the cylinder 3 at the location of the receiving table 15.
    As shown in Figure 4, when a dough piece 2 arrives on the receiving table 15, a possible surplus of the fabric is returned to the reserve 12, as indicated by the arrow 13, following the friction between the circulating belt 1 and the band 6.
    The distance between the receiving table 15 and the lower part of the endless belt 1 is preferably kept greater than or at least equal to the diameter of the shaped dough piece 2 after it has passed between the belt and said belt. Thus, the dough piece 2 detaches from the mat 1 by the action of gravity and can be removed for further processing.
    According to an interesting embodiment, the distance between the belt 1 and the reception table 15 gradually increases from the point where the strip 6 merges with this reception table 15. Thus, the reception table 15 can, for example, example, present a slope to allow the dough pieces 2 to advance automatically on this reception table 15.
    The invention is of course not limited to the embodiments described above and shown in the appended figures, but many other variants could be envisaged without departing from the scope of the invention.
    Thus, it is, for example, possible that the endless belt extends around a single cylinder, so that the belt constitutes the surface of that cylinder. It is also possible that the endless belt is guided on more than two parallel cylinders.
    In the embodiment of the invention shown in the figures, the endless belt 1 extends horizontally upstream of the cylinder 3 or between the parallel cylinders 3 and 4. It goes without saying that it is also possible that the belt has a small inclination from horizontal.
    In other embodiments of the invention, the strip fabric reserve 6 may be formed by a fabric reserve which is wound around a roll and which is wound up under the action of, for example, a spring. or an electric motor.
    It is also possible that this reserve of canvas for the strip is achieved by the presence of a spring which holds said second end of the strip.
    Thus, when a tensile force is exerted on the strip, for example, by the presence of a dough between the strip and the carpet, the fabric is supplied by the extension of the spring.
    It goes without saying that still other embodiments of the canvas reserve are possible.
    Thus, a part of the fabric which is wound around the second end and which can be unrolled, can also constitute a reserve according to the invention.
    In some embodiments of the machine, according to the invention, it is possible that the first end 7 of the strip is maintained at a fixed position and this position is not necessarily adjustable.
    There are also other possibilities to control the position of the part of the web between the cylinder and the first end, in particular, to adjust the angle between this part of the web and the belt.
