  • This station comprises fiber-optic positioning means 98 for ensuring precise angular alignment of the transfer disk 78 .
  • a pusher 99 is mounted to slide along an axis passing through the center of the transfer disk 78 . The front part of this pusher 99 has a smaller diameter than the rear part, so as to be able to enter the bore of the straw P to keep the straw aligned by pushing it into a housing 82 b secured to the transfer disk 78 .

  • the operations relating to the straw loading station 2 are performed on the sheath G while it is stationary, as are those at the first welding and cutting station, whereas the second welding and cutting station 4 is also used to advance the sheath step by step and therefore makes a reciprocating vertical movement at the same time as the welding and cutting operations, the operations of the straw loading station 2 and of the first welding and cutting station 3 are performed between the operations of the second welding and cutting station 4 .
  • liquid feed pipe 41 extends down as far as a level mid-way up the height of the cutting tools 42 , 43 (FIGS. 1, 2 and 4 ), that is to say a level situated appreciably below the first welding station, thus allowing liquid to be fed in at a continuous and constant flow rate without the liquid overflowing.
  • the straw loading station 2 first of all performs the operation of puncturing the film that seals the entry to the valve V.
  • the actuators 92 , 93 clamp the bearing and clamping surfaces 87 - 91 against each other, immobilizing the sheath G.

  • the actuator 96 retreats and the slide 82 is moved back by the return springs 83 .
  • the motor 80 causes the transfer disk 78 to rotate through 30°, corresponding to one angular spacing separating two adjacent slides 82 , in order to position a slide 82 into which a straw P has been loaded.
  • the actuator 96 is then actuated once again to engage the front end of the straw P in the passage in the valve V.
  • the depth to which the straw P is engaged in the valve V is chosen so that the valve remains closed.
  • the actuator 96 returns to its initial position and the springs 83 return the slide 82 back, while the straw P remains engaged in the passage in the valve V.

  • the welding electrodes 38 , 39 are then powered with pulses of current to perform the welding of the sheath G.
  • the actuator 44 is actuated to cause the cutters 42 , 43 to enter the receiving grooves facing them and of which just the groove 46 is visible in FIG. 4, thus cutting the sheath G on the outside of the welds formed by the electrodes 38 , 39 , and thus separating them from the remainder of the sheath G.
  • the welding electrodes 38 , 39 and the cutters 42 , 43 lie at two different levels, which means that the welding and cutting operations performed almost simultaneously by the welding and cutting station are performed on two different bags following on from one another along the sheath G. In this way, one bag is welded while the one just below it is being filled with liquid and at the same time cut. During the next operation cycle, the bag that was welded is lowered by one spacing and therefore finds itself facing the cutters 42 , 43 .
  • FIG. 11 The sequence of events in the welding and cutting operations at the second welding and cutting station 4 is illustrated in FIG. 11, referring more especially to FIGS. 5 and 6.

  • all of the members mounted on the chassis 47 will be driven downward by the linear motors 50 , 51 .
  • the length of the downward travel will correspond precisely to the length separating two successive bags or to the length separating two successive valves V, which amounts to the same thing.
  • the valves V are formed on the sheath G at regular and precise spacings before the operation of packaging liquid into the bags, the bags are not formed until during the packaging operation, at the same time as this, which means that it is the valves V which serve as marker means.
  • the actuators 64 , 66 controlling the welding tools 68 , 69 corresponding to the electrode and to the opposite welding electrode press these tools against each other.
  • the electrodes are powered with current in pulses, making it possible to limit the welding time, then to immediately cool afterwards in an extremely short space of time, it being possible for the opposite electrode 69 to serve as a cooling member by being connected to means (not depicted) for example a bimetal with Peltier effect, to quickly lower its temperature, while at the same time keeping the welded parts clamped together, something that cannot be achieved with resistive heating.
  • the cooling following the welding keeping the parts clamped together is important in this case. This is because at the time of this welding, the bag is full of liquid and has therefore been deformed, which means that the welded surface would crumple. By keeping it clamped as it cools, the appearance of this welded portion is markedly improved.
  • the actuators 64 , 66 are opened and it is the turn of the runners 57 , 58 to be moved by the drive motors M 1 , M 2 , M 3 , M 4 in order to bring the cutting tools 72 , 73 into the place of the welding tools, that is to say by moving the runners 57 , 58 to the right with respect to FIG. 5.
  • the actuators 59 and 60 that move the cutting tools 72 , 73 closer together, causing the cutters of the tool 73 to protrude in order to cause them to enter the grooves in the cutting anvil tool 73 , cutting as it passes the portion of sheath G corresponding to the portions welded before. It can be seen from FIG.
  • the welded portions and the cut portions are used to connect together the two portions already welded by the electrodes 38 , 39 (FIG. 2) and cut by the cutters 42 , 43 , on each side of the space 40 left free to allow the passage of the liquid feed pipe 41 .
  • the first welding and cutting station 3 performs the welding and cutting operations on two successive bags respectively
  • the second welding and cutting station 4 performs welding then cutting of two lower and upper parts respectively of two successive bags simultaneously.
  • the lower bag, the upper part of which has been welded is separated from the sheath G after the cutting operation.
  • the actuators 59 , 60 are returned backward, and then it is the turn of the actuators 53 , 54 to be returned backward.
  • the sheath G is lowered by a spacing corresponding to the height of a bag, so that the first welding and cutting station 3 can recommence its operating cycle.
  • the chassis 47 of the second welding and cutting station 4 is returned upward by one spacing by the linear motors 50 , 51 .
  • the actuator 96 pushes the radial slide 82 toward the valve V so that the perforator 84 perforates the film that was closing the entry to the passage in the valve V.
  • the sheath G and the valve V are assumed to have been configured as described in EP-0 948 446 to which reference may be made. However, the invention may also obviously be applied to other types of bags equipped with valves.
  • the return springs 83 return the slide 82 backward, with the perforator 84 .
  • the motor 80 then drives the transfer disk through one spacing, in this example this spacing corresponding to 30°, thus placing the next slide 82 bearing a straw P on the line connecting the center of the transfer disk 78 to the passage in the valve V.
  • the actuator 96 is once again actuated to push the slide 82 and engage the straw P in the passage in the valve V.
