Definitions

  • Patent FR-A-2 678 897 describes a device for bagging breads which includes, in addition to a mechanism for unrolling a continuous sheath and vertical guidance from the open end of the latter, a fixed collar crossed by said end and a removable chute introduced into the sheath and intended to receive a bagging bread, the elevation manual chute and bread resting on the end closed of it allowing a welding mechanism to operate closure of the sheath portion and sectioning of it.
  • the present invention aims to allow the realization an automatic bagging system which, while taking advantage of the concept of the prior arrangement above mentioned, is adapted to industrial rates in minimizing, if not eliminating, interventions manual.
  • Document FR-A-2 151 724 (PROGES) describes a machine for the formation of sachets from a sheath of material heat sealable and for the introduction of objects into said sachets.
  • This machine includes a drum from which the sheath, an opening member fixedly arranged in said sheath applied against said organ by external means, organs for gripping the free end of the sheath, these organs being moved to stretch a portion of the sheath, and a welding device to close it below and above of the object which has been introduced in the aforementioned portion, the lower member of this device being arranged to cut the sheath and thus release the bagged object.
  • Such a vertical machine does not respond to the problem posed, namely to ensure the automatic packaging of breads, since the introduction of each loaf into the portion of sheath is still a manual operation.
  • Document EP-A-23 831 (KUREHA KAGAKU) relates to a process and a vacuum packaging machine comprising a device for automatic bagging of products.
  • a continuous sheath is unwound and moved axially before being opened to allow insertion a bagging object, which sheath is then cut to authorize the evacuation of said object wrapped in its portion of sheath.
  • the invention essentially consists in imparting to each bread a high speed launch movement so that said bread penetrates like a projectile inside the end of the sheath suitably kept open.
  • the installation shown in fig. 1 understands first place a feeding device incorporating a support, shown schematically in 1, for a 2 'roll of a bagging sheath 2 capable of being rolled up in a flattened form and being open by spacing the walls.
  • the free end of this sheath 2 is returned to the horizontal by a guide 3 for extend to a feed mechanism 4 which has been detailed in fig. 2 and 3.
  • This mechanism includes a lower roller 5 driven by the motor referenced 6 in fig. 1, and an associated upper roller 7 to elastic means 8 which tend to press it towards the low.
  • These opposite rollers 5 and 7 are associated with four counter-rollers of smaller diameter, arranged in pairs and carried by a die 9 introduced inside the sheath 2, which die is retained by the cooperation of the rollers and counter-rollers cited above.
  • the vertical face of the die 9 which is turned towards the upstream is provided with a wedge-shaped spacer 10, while the opposite face carries an opener 11 with lateral profile C-shaped, capable of collapsing to allow the welding of the sheath 2, as will be better understood below.
  • the supply device also includes a blower 12 (fig. 1) which is oriented so that the flow of air is directed towards the end of the sheath 2 which is thus kept open, in combination with the deformable opener 11 mentioned above.
  • a blower 12 (fig. 1) which is oriented so that the flow of air is directed towards the end of the sheath 2 which is thus kept open, in combination with the deformable opener 11 mentioned above.
  • the installation includes a introduction station which includes two endless belts 13 and 14 arranged in horizontal alignment along the axis of the assembly, that is to say in the axis of the advance mechanism 4.
  • the belt 13 is equipped with an upstream support 15 with a V profile which is intended to support the rear part of a P bread temporarily stored on said mat 13 assumed to be stopped. Timely, the belt 13 is put into operation and transmits the bread P to belt 14, which moves continuously.
  • the mat 14 has a rough surface and moves at very high speed, in order to throw the bread P towards the open end of the sheath 2 inside which it penetrates like a projectile.
  • a fixed table 16 Between the end of the launcher mat 14 and the mechanism in advance 4 is provided a fixed table 16 above which is mounted a pad 17 (fig. 2 and 3) intended to move vertically to immobilize the bread P launched inside the sheath 2.
  • this buffer 17 is carried by an arm horizontal 18 secured to one of the two movable jaws 19 and 20 of a conventional type welding device.
  • Each jaw 19 and 20 is equipped with a shaping pad 21 and a welding jaw 22, the jaw 19 being further provided a vertical sectioning blade 23.
  • a fixed table 16 is associated with a discharge device which includes two parallel chains 24 driven by jerks successive by a single motor 25.
  • Each chain 24 supports three stops 26 which, suitably positioned on said chains, protrude above the table 16.
  • the advance mechanism 4 is energized so that the sheath 2 extends above the table 16 and protrudes in before it, the movement being stopped by means of detection using a schematic photoelectric cell in 27 in fig. 1.
  • the entry belt 13 goes into action to transfer the bread P to the mat 14 which thus projects this bread into the end of the sheath 2 maintained opened by the air flow from the blower 12.
  • the welding device is activated and the lowering of the upper jaw 19 causes the tampon 17 to drop, which immobilizes the bread P in the sheath 2.
  • the opener 11 resumes its normal profile elastically and ensures the opening of the end of the sheath 2.
  • the introductory station 13-14-15, the blower 12 and detection cell 27 are advantageously mounted on a movable frame 31 capable of being adjusted in horizontal position.
  • the installation is thus susceptible to be easily adapted for bagging P loaves of lengths different.
