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 along its length where it is supported by the cooperation of bearings and rollers in the aim of continuously ensuring the following operations: widening of the flat continuous sheath coming from a roll feed, introduction onto the mandrel, downward transfer of the shaped sheath, cutting of the latter into sheath sections or sleeves adequate predetermined length and deposit sleeves around the containers to be coated and / or to be decorated (patent application EP.A.0048656).
  • US-A-2 846 835 discloses a device for installing and centering a sheath around an object which comprises a vertically floating mandrel, supported by lifting means and provided in its lower part a vertically movable part, and means for actuating the movable part from the outside.
  • the sheath material is pinched between pliers pivotally mounted and the vertically movable part, which has the shape of a sleeve sliding on the mandrel inside the sheath. The pliers are lowered so that the lower end of the mandrel covers the head of the object, the sleeve follows the movement of the pliers, and a section of sheath is thus lowered onto the object.
  • the sheath is lowered by being pinched between rollers and movable fingers located inside the sheath.
  • a device is disadvantageous in that the sheath is not free from any movement, which can be annoying when the device comprises sheath advancing means clocked.
  • the mandrel must be lowered entirely on said head, which is often impossible or undesirable in practice.
  • the object of the present invention is to obviate the aforementioned drawbacks and to propose a device for laying and centering a sheath on an object in which provisional continuity can be ensured between a mandrel and the head of said object from the outside without obstructing the free movement of the sheath, often controlled by an independent device without having to lower the entire mandrel onto said object.
  • the present invention relates to a device for fitting and centering a sheath or a thermoplastic sleeve around an object according to claim 1 appended.
  • the present invention relates to a device for installing and centering a sheath or a thermoplastic sleeve around an object according to claim 4 appended.
  • 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 of the latter 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, the middle and bottom parts of which can be seen in FIG. 1, is designed according to a known general principle described in patent application EP-A-0048656.
  • the driving drive rollers 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 down.
  • 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.
  • rollers 13 are carried by support arms 15 which, by virtue of an associated device provided with a cam and not shown here, perform a so-called "square" movement comprising the phases following: approach of 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 horizontally 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 is glued onto the mandrel.
  • This critical point can correspond for example to the distance between the head and the body of the container or to a particular conformation of the top of the container (set with a can ... etc).
  • the sheath is cut into sections or sleeves by a device already known per se and not shown (see for example the aforementioned European patent) 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 points 16 and 17-clearly visible in Figure 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 impression 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 imprint 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 roller 13 but to two rollers, 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 11 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.
