Definitions

  • Plastics such as polyethylene, polypropylene, nylon are more elastic than malleable and give the walls of the tubes a "memory". After a temporary deformation, the wall tends to return to its original shape. Thus, when an empty plastic tube is closed by mechanical clamping, it tends to resume, when it is released, its initial tubular shape.
  • Plastic tubes or metal and plastic complex tubes cannot be closed by simple bending and stripping, as is the case with aluminum tubes, which remain folded and flattened.
  • the tubes of which at least the internal surface is made of thermoplastic material are closed by welding this internal face on itself.
  • the tube should be pinched before welding, and kept pinched long enough for the weld to cool and resist the tendency of the tube to return to its original shape.
  • French patent 1 069 414 describes an automatic machine where the filling and closing by pinching and welding of flexible plastic tubes takes place. This machine also has clamping jaws which accompany the tubes in their movement. These jaws which are identified 20 and 21 in this patent move on either side of the tubes by sliding on guides in a horizontal plane above the plate of the machine.
  • the object of the invention is a device of the vice grip type, one of the jaws of which, when not in use, but in the open position, disappears above its work surface by rising substantially above the other jaw.
  • the two jaws are each actuated by at least one control rod sliding radially on the machine.
  • the rod controlling the external jaw has its end articulated in a vertical plane, this over a length corresponding substantially to the spacing of the two jaws in the open position, while a return means tends to hold the articulated end of the rod in vertical position and thus raise the external jaw.
  • the internal jaw moves in a horizontal plane by resting on the control rod of the external jaw.
  • it presses on the end of the control rod of the external jaw and returns this rod to the horizontal position, this brings the external jaw back into the work surface of the internal jaw which allows both jaws to exercise their clamping function in a horizontal plane.
  • FIG 1 is shown schematically a revolver plate 1 rotating around a vertical axis 00 '.
  • This tray 1 comprises 16 work stations numbered from 2 to 17 each comprising a housing 18 intended to guide a tube 19. Each station also includes a pair of jaws 20-21 secured to the tray by means of control rods 22-23 .
  • the housing 2 is empty. It will be lined with a tube 19 similar to the one seen in plan at station 3 in its housing 18.
  • Station 3 is a post for adjusting the vertical position of tube 19.
  • Station 4 is used to tighten the plug.
  • Station 5 is a tracking station.
  • the tube 10 is rotated and stopped for a defined position of the marker so that the printed pattern has a defined position relative to the transverse weld line produced at the following stations.
  • Station 6 is a filling station.
  • Station 7 is a vacant station.
  • Station 8 is a height-setting station and, possibly, a tube cut.
  • Stations 9-10-11-12 are preheating and then welding stations where the jaws 20-21 are clamped on the tube orifice to close it definitively.
  • Station 13 is a sorting-marking-cooling station.
  • Station 14 is a stabilization station.
  • Station 15 is a height cutting and stabilization station.
  • Station 16 is a stabilization station
  • Station 17 is an ejection station.
  • the outer jaw 21 is also lowered to positions 7-8-13-14-15 and 16. By against, at positions 2-3-4-5-6 and 17, the outer jaw 21 is raised as shown in FIG. 2 or 5.
  • the tube 19 can be accompanied or, on the contrary, released flush with its housing 18.
  • Figures 4 and 5 show in detail the device allowing the external jaw 21 to rise above the jaw 20 when it is in the open position.
  • the jaws 20-21 are respectively actuated by the rods 22-23 which slide radially while being guided by a support 25.
  • the rod 22 has a hinge pin 24 and a spring 26 which tends to return the end 27 of the rod 22 in the vertical position, and therefore the jaw 21, in the raised position, substantially above the internal jaw 20.
  • the jaw 20 is integral with a roller 28 which rolls on the rod 22.
  • the roller 28 passes vertically above the axis 24 and pushes the end 27 of the rod 22 in a horizontal position.
  • the two jaws 20-21 are then opposite one another in the same horizontal plane and can effectively pinch a tube 19.
  • each jaw 20-21 is here actuated each respectively by a single rod, but it is obvious that each jaw 20-21 can be actuated by a pair of rods symmetrical with respect to the radial plane passing through the axis of the corresponding housing 18 .
