Definitions

  • the present invention relates to the field of equipment intended for laying around objects, including various containers and containers, of sections of sheath or sleeves derived from a flat sheath of heat-shrinkable plastic. It especially relates to a process of the floating mandrel type for fitting and centering sleeves, in an automatic machine supplied with a flat continuous sheath of heat-shrinkable plastic, whether or not printed.
  • the machine for fitting sleeves from a continuous thermoplastic sheath is constituted by a vertical assembly with floating mandrel provided with a narrowing over its length where it is supported by the cooperation of bearings and rollers-supports with the aim of continuously ensuring the following operations: widening of the continuous flat sheath from a roll feed, introduction onto the mandrel, downward transfer of the shaped sheath, cutting of the latter into sheath sections or sleeves of adequate predetermined length and removal of the sleeves around the containers to be coated and / or decorated (French patent application No. 80 20 301 of September 22, 1980).
  • the object of the invention is to obviate the aforementioned drawbacks and to solve the delicate technical problem of the continuity to be ensured between the mandrel and the container to be sleeved when the sheath is lowered onto the container of special conformation mentioned above. It also aims to ensure very good centering of this receptacle under the mandrel intended for the removal of the sheath.
  • the invention proposes an improvement to the floating mandrel of known type containing in its hollow lower part a movable part at the end of which is fixed an imprint intended to come over the head of the object to be sleeved.
  • a movable part at the end of which is fixed an imprint intended to come over the head of the object to be sleeved.
  • the up-down operations of the movable part and its imprint within the floating mandrel are carried out from the outside of this mandrel and during the descent of the sheath by exclusively mechanical means.
  • the movable part internal to the mandrel and terminated by the impression on the outside of the latter, consists of a spring rod provided with first elements, arranged in an opening of the mandrel, suitable to cooperate by contact with second elements actuated from the outside to come to bear, at a predetermined rate, on said first elements.
  • each group of said elements consists of rollers or bearings which, when brought into contact for a predetermined time, bring down the sheath which surrounds the mandrel as well as the moving part and its imprint of so that the latter comes to cap the container ensuring its centering.
  • the device is part, as the main member, of an automatic machine continuously supplied by a flat sheath of heat-shrinkable plastic and intended to carry out the successive operations of opening the sheath, transfer thereof to a cylindrical mandrel here with speed programming, removal and cutting of the sheath into sections or sleeves of predetermined length around the container to be sleeved then heat shrinking with a heating device mounted for example on an endless conveyor.
  • the sheath supply means and those for heat shrinking can be, for example, those described in European patent No. 0 000 851.
  • the floating mandrel 1 is designed according to a known general principle described in French patent application No. 80.20301. Inside the constriction 2, the drive drive wheels 3 and 4 come into contact with the bearings of the abutment 5 and 6 and serve both to keep the mandrel 1 in vertical lift and to drive the thermoplastic sheath 7 towards the bottom.
  • the part of the mandrel located under the constriction 2 is hollow and provided with a movable part, for example here of the piston type 8 at the lower end of which is fixed a hollow imprint 9 intended to see the head of the object to be capped. sleeving (not shown).
  • the movement of this piston was controlled by induction by means of an electrostatic coil of dimension slightly greater than the mandrel.
  • the moving part is driven from outside the mandrel by purely mechanical means.
  • the rod 10 of the movable part provided at its lower part with a spring sheath 11, comprises a pair of rollers 12 (only one is shown in Figure 1) which cooperate , by momentary contact, with the rollers 13 operated from the outside of the mandrel, the latter having a recess 14 in the zone of action of said rotary elements.
  • the internal movable part is driven from the outside with its centering imprint 9 in an up and down movement, at a predetermined rate, with automatic return to the high position by the action. of spring 11.
  • the rollers 13 are carried by support arms / which, by virtue of an associated device provided with a cam and not shown here, perform a so-called "square" movement comprising the following phases: approaching the mandrel horizontally until contact with the rollers 13 and rollers 12, descent along the mandrel during the pressing of 13 on 12 (the sheath 7 moving between these two bearings), then spacing horizontal of the arms 15 to allow the imprint 9 to rise on the base of the mandrel 1 by the action of the spring 11 and, finally, rise of the support arms 15; the cycle repeating again as said above.
  • the distance or value of spacing of the arms 15 is adjustable as a function of the diameter of the mandrel and the length of descent of the arms along the mandrel is that corresponding to the distance between the head and the body of the container to be sleeved.
  • the output of the impression 9 from the base of the mandrel 1 takes place just before the triggering of the descent of the sheath 7 on the mandrel. Once this descent is started, the container is capped over the impression with the sheath, the support arms (15) are moved aside and, under the effect of the spring 11, the impression - comes to you. put back on the mandrel.
  • This critical point can correspond for example to the distance between the head and the body of the container or even to a particular conformation of the top of the container (seiti of a can ... etc). Cutting the sheath into sections or sleeves by a device already known per se and not shown (see for example patent above) is carried out when the sheath has arrived at the bottom of the container.
  • the timing of the internal movable part of the mandrel is ensured, at the level of the piston 8, by a double set of lip seals 16 and 17 - clearly visible in FIG. 3 - which oppose the ascent immediate of the rod 10 when the imprint 9 is in a timed position for capping the container to be sleeved.
  • This seal device can be replaced by a system with equivalent function, such as for example a counterweight with thread.
  • the support arm 15 may not pivot and move away from the mandrel 1 during the ascent of the imprint 9.
  • the caster 13 remains permanently in contact with the roller 12 not only during the descent of the sleeve but also during the ascent of the footprint 9. In such an operation, it is the power of the spring 11 which allows the contact between 12 and 13 to be maintained.
  • the support arm 15 can no longer be connected to a single caster 13 but to two casters, high and low, numbered 13 and 13 ′ and which trap the internal roller 12, the upper roller 13 ensuring the descent of the sleeve while the lower roller 13 'ensures the ascent of the imprint or cap after depositing the sleeve on the container.
  • the return spring II of the imprint 9 can be omitted and a series of double rollers and of the roller can be provided either on one side of the mandrel (as in FIG. 6) or on two opposite sides on the same horizontal plane.
  • the aforementioned systems of support arms / rollers / rollers can no longer be arranged below all of the bearings (designated 3-4; 5-6) which are used to hold the mandrel (1) in vertical lift but just as well above this assembly.
