Definitions

  • the invention relates to a method and a machine for covering the lateral faces of a load with a strip of plastic film.
  • a method and a machine are already known for covering the lateral faces of a load with a strip of plastic film coming from a film reel.
  • the load is placed on a support table; the initial free end portion of the film is maintained and associated with the load; a relative movement of the load is carried out on the support table with respect to the film reel in order to place the film on the lateral faces of the load; the film is cut transversely; and the end free end portion of the film is secured to its middle part covering the load and a new initial free end part of the film is maintained.
  • a known machine comprises a horizontal load support table; means for supporting a film reel with at least substantially vertical axis; drive means suitable for carrying out a relative movement of the load with respect to the film strip coming from the reel, around a vertical axis; holding jaws of the initial free end part of the film, movable between a closed holding position and an open non-holding position; means for transversely cutting the film; and means for securing the terminal free end part of the film to its middle part covering the load.
  • the support table is pivotally mounted about a vertical axis and the film reel has an axis fixed.
  • the load support table is fixed and the axis of the coil is moved along a loop surrounding the table, for example circular.
  • a first embodiment corresponding to a process and to a semi-automatic machine consists in manually hanging the initial free part film to the load, in particular by tying it to the load support pallet. This first variant does not allow full automation of the process and the machine.
  • a second embodiment allowing this automation consists in applying the initial free end part of the film to the lateral face of the load, in the zone to be covered, by means of a retaining finger.
  • the finger is covered in the holding position with one or more layers of film, which thus makes it possible to maintain the initial free end portion of the film.
  • the finger is then retracted below the support table by sliding it between the two layers of film where it was previously placed
  • a third variant as known from document US-A-4077 179 also allowing automatic operation, consists in maintaining the initial free end portion of the film in the immediate vicinity of the lateral face of the load in the area to be covered, by means of a holding clamp.
  • This clamp is also covered with one or more layers of film, which makes it possible to maintain the initial free end part. We then retract the clamp by rotating and sliding between the two layers of film where it was previously located.
  • a single holding clamp is provided, generally associated with the support table.
  • two clamps are provided, associated, on the one hand, with the support table and, on the other hand, with a presser applied to the upper horizontal end face of the load.
  • This cutting pliers also includes a brush for applying the extreme free end part of the film to its central end part.
  • the initial free end part of the film is associated with the load because it is trapped and maintained by the middle part of the film overlapping and itself clamping the load as a result of the stretching to which it is subject.
  • These last two variants allow automatic operation but have, however, a certain number of limits: the finger or the holding clip associated with the support table risks being damaged by the loads when they are brought in or removed; it occupies an appreciable bulk which can lead to raising the table; being placed in the lower position it can see its operation affected by what may fall from the load (for example in the case of a friable load).
  • a fourth variant is illustrated by document US-A-4 216 640 which describes a machine according to the preamble of claim 10, in which the holding jaws are associated with the rotary table, this machine however being devoid of presser.
  • the initial free end part of the film is kept outside the zone where the charge is covered with the film strip. It follows that the holding jaws do not interfere with the film strip overlapping, which avoids covering the holding jaws with the film strip, therefore retracting these holding jaws by sliding between two layers of successive films. It follows that the film is not likely to be damaged by such sliding, that the stretching of the film may be greater since it does not risk preventing the retraction of the holding jaws.
  • a claw carried by a first arm pivotally mounted on a second vertically sliding arm with which a presser is associated.
  • This claw pulls the film from the reel to pass it under the presser away from the upper face of the stack, through a passage.
  • the presser ensures the association of the film with the stack.
  • the claw is not carried directly by the presser and is therefore not slaved to its movement. The claw remains fixed during the wrapping while the presser pivots.
  • the claw is associated with a separate and complementary holding device.
  • the invention therefore aims to remedy these drawbacks and, to this end, it provides a method and a machine for covering the lateral faces of a load with a strip of plastic film coming from a film reel, of the type previously mentioned.
  • the inventive method is characterized in that in order to associate the initial free end portion of the film to be loaded, the middle region of the initial free end portion of the film strip is applied astride a first corner of the load partly on its end face and partly on its lateral faces to locally locally plastic deform the film, the latter being pressed between the first corner and unable to be released therefrom; and the maintenance of the initial free end portion of the film strip is stopped after at least a relative half-turn and before a relative turn of the load relative to the film reel.
  • a machine according to the invention of the type mentioned above and for implementing the method is characterized in that in combination the holding jaws are carried on a pressure plate leaving at least one corner of the load projecting above the above the upper end face of the load, said presser being carried by an axis mounted on an arm and pivotally movable about an axis, the jaws holding in the holding position for hooking the free end part initial film on the protruding corner of the charter extending in a direction inclined orthogonally to the axis of the film reel and being vertically offset from the film reel placed opposite the load.
  • the holding jaws being preferably placed in the high position, associated in a presser, they are not likely to be damaged by the load or to interfere with it during its movement. Similarly, it is possible to provide a support table whose level is lowered. The high position of the retaining jaws allows the initial free end portion of the film to be attached to a first corner of the load.
  • the invention therefore relates to a method and a machine for covering the lateral faces 1a, 1b, 1c, 1 of a load 2 with a strip of plastic film 3 coming from a reel 4.
  • a machine for implementing the method comprises a frame 5 comprising a sole 5a and a column 5b; a horizontal table 6 load support 2, support means 7 of the film reel 4 whose axis 8 is at least substantially vertical; drive means (not shown) capable of carrying out a relative movement of the load with respect to the film strip 3 coming from the reel 4 around a vertical axis 9; a holding clamp 10 of the initial free end portion 3a of the film strip 3, consisting of two jaws 10b, 10c movable about an axis 10a between a closed holding position ( Figures 1 to 4 and 8) and a position non-holding open ( Figures 5 to 7); means for cross-cutting 11 of the film strip 3; means 12 for securing the terminal free end part 3c of the film strip 3 to its middle part 3b covering the lateral faces of the load 2.
  • the drive means are such that the table 6 is pivotally movable about the axis 9 and that the axis 8 of the coil remains fixed, near the column 5b.
  • the invention also applies to the case of a fixed table 6 and a film reel 4 whose axis 8 rotates around table 6.
  • a helical wrapping is produced.
  • the invention also applies to the case of the removal of a strip.
  • the film used is preferably a stretch film and the machine may include a pre-stretching device, not shown.
  • the different parts of the film strip 3 are designated as follows: the initial free end portion 3a divided into an upstream section 3a-b on the side of the free end 3a-a and into a downstream section 3a-c; a middle part 3b adjoining the initial free end part 3a and a terminal free end part 3c; the middle part 3b being itself divided into an initial middle part 3b-a, a central middle part 3b-b, a terminal middle part 3b-c; a waiting part 3d, placed between the load 2 or the holding jaws 10 and the coil 4; a part wound 3rd on the reel 4.
  • the load 2 is a load carried by a pallet 2a and it comprises, in addition to its lateral faces 1a, 1b, 1c, 1d, two end faces, respectively upper 13a and lower 13b, the latter resting on the pallet 2a.
  • the machine comprises a presser 14 carried by a pin 15 mounted on an arm 16 supported by the column 5b at its upper part.
  • the presser 14 is applied to the upper end face 13a of the load 2. It is pivotally mounted to pivot about the axis 9.
  • the load 2 is placed on the support table 6; the initial extreme free part 3a of the film is maintained and it is associated with the load 2; a relative movement of the load 2 is carried out on the support table 6 relative to the film reel 4 in order to place the film on the lateral faces of the load 2; the film strip 3 is coated transversely; the end free end portion 3c of the film strip is secured to its middle part 3b covering the load 2 and a new initial free end part of the film is maintained.
  • the latter is applied astride a first corner 17a of the load 2 (FIG. 2).
  • the middle zone of the initial free end portion 3a is applied to the first corner 17a.
  • This application is such that a local plastic deformation of the film is obtained. Indeed, it is applied to the first corner 17a which is projecting and more or less pointed at its end.
  • the initial free end portion 3a is applied to the load 2, in particular the first corner 17a, while the film strip 3 is kept under pre-stretched tension.
  • the initial middle part 3b-a of the film strip is applied to an additional corner 17b of the load.
  • the initial middle part 3b-a is applied to the three other successive corners 17b, 17c, 17d of the load 2.
  • downstream section 3a-c of the initial free end portion 3a is applied to the first corner 17a.
  • the initial free end part 3a is twisted, in particular the upstream section 3a-b before applying it to the load 2, in particular by approximately 90 °.
  • the initial free end portion 3a of the film strip 3 is therefore applied in part to the end face 13a of the load, in part to its lateral faces 1a, 1b.
  • the upstream section 3a-b is left free. Subsequently, it is covered with the middle part 3b. To this end, the retaining clamp 10 is partially opened and the film section 3a-b is folded down by the internal jaw 10c onto the first layer of film trapping the corners 17d and 17a. The maintenance of the initial free end portion 3a is stopped after at least half a turn and before one turn of the support table 6.
  • the initial free end 3a-a is kept axially offset with respect to the film reel 4. Also, at least initially, the free end 3a-a is kept inclined - in particular at least substantially orthogonally - with respect to to the axis 8 of the film reel 4.
  • the initial free end 3a-a is kept offset from the zone to be covered by the reference lateral face 1a of the load, that is to say the face from which the holding is carried out. of the film.
  • the initial free end 3a-a is maintained at least substantially parallel to or slightly inclined relative to the edge 18a defined by the lateral face la and the end face 13a.
  • the initial free end 3a-a is maintained above the upper end face 13a.
  • the first corner 17a is preferably an upper corner of the load 2.
  • a double helical wrapping is applied. This comprises a first descending interior helical wrapping, then a second exterior ascending helical wrapping.
  • the initial free end part 3a of the film strip 3 is associated with the load 2 because the first projecting corner 17a sufficiently deforms the film which is stretched and twisted so that the film is pressed against the first corner 17a and cannot be released from it.
  • the holding jaws 10 are, 'at least in the closed holding position, offset axially relative to the film reel 4. In this position, the holding jaws 10 extend in an inclined direction - at least substantially orthogonally - relative to the axis 8 of the coil 4.
  • the holding jaws 10 are at least partially offset axially with respect to the film reel 4.
  • the holding jaws 10 are released from the film so that the film strip 3 does not do not come to substantially cover the jaws 10.
  • the jaws 10 are offset vertically with respect to the area to be covered with the reference lateral face 1a so as not to be located facing it.
  • the jaws 10 extend in a direction at least substantially parallel to or slightly inclined relative to the edge 18a. Consequently, the holding jaws 10 in the closed position extend in a direction at least substantially parallel or slightly inclined relative to the longitudinal direction of the film strip 3 covering the load.
  • the holding jaws 10, in the closed position, on the one hand, are offset with respect to the reference lateral face la and, on the other hand, extend at least substantially parallel and close to an end face 13a.
  • the jaws 10, in the closed position extend in an at least substantially horizontal direction and above the upper end face 13a. This is why the holding jaws 10 are preferably carried by the presser 14.
  • the articulation axis 10a of the holding jaws 10 is located on the side which deviates from the coil 4.
  • the holding jaws 10 are associated, on the one hand, with first drive means allowing the jaws to be opened and closed, and, on the other hand, with second drive means, separate or not from the first means of drive, allowing the jaws to pivot together around their articulation axis 10a.
  • the drive means are housed in a casing placed on the upper face of the presser 14.
  • the first and second drive means are constituted by electric, pneumatic or other motors.
  • the cross-cutting means 11, on the one hand, and the means for securing the film 12, on the other hand, are preferably carried by the holding jaws 10. This is made possible even with a larger size of the holding jaws 10, since these do not have to be housed between two successive layers of the film strip 3.
  • the cross-cutting means consist of teeth carried by one of the jaws, cooperating with an opposite recess carried by the other jaw.
  • the means for securing the film 12 comprise means for applying the film to itself (variant shown) such as a flap, fringes, a roller or heat sealing means with electric or magnetic control.
  • the support means 7 of the film reel 4 remaining fixed, the table 6 is rotated about the axis 9, thanks to the drive means, the jaws 10 remaining closed and the pre-stretching device used.
  • the upstream section 3a-b of the film strip 3 extends between the jaws 10 and the first corner 17a with which the strip 3 interferes. This interference necessarily occurs, due to the offset existing between the jaws 10 and the coil 4.
  • the upstream section 3a-b is twisted, which promotes the maintenance of the film on the load 2.
  • the upstream section 3a-b is a sufficient length so that the first corner 17a is sufficiently spaced from the free end 3a-a. This is why, the axis 10a is preferably placed in the vicinity of an anal of the presser 14.
  • the first corner 17a interfering with the film strip 3 comes to deform it locally, the film being firmly applied to the load 2 around the corner 17a ( Figure 2).
  • the downstream section 3a-c and the initial middle part 3b-a are covered.
  • the holding jaws 10 are then opened to release the free end 3a-a, therefore the initial free end part 3a.
  • the upstream section 3a-b not yet covered by the strip of film trapping the corners 17d-17a is folded over the first layer, and this by means of the inner jaw 10c, the clamp 10 being partially open.
  • the outer jaw 10b is held vertically and downward, while the inner jaw 10c is pivoted upward, horizontally.
  • the overall movement of the jaw 10 down makes it possible to bring down an upstream section 3a-b (FIG. 5).
  • the clamp 10 is immediately closed in a horizontal position.
  • the film reel 4 is again in its original position and the jaws 10b-c placed on either side of the film strip 3. They are then closed. They are placed vertically (FIG. 7) ensuring the cutting of the film on the load side and the maintenance on the reel side.
  • the end free end portion 3c of the film can be applied to the middle part 3b for a view. to secure the connection (self-adhesive film for example). This is optionally carried out by additional heat-sealing members 19- or other means of securing (non-sticky film).
