Definitions

  • the invention relates to the technical sector of packaging films.
  • stretch plastic film It is known to use, to maintain various loads on pallets, stretch plastic film.
  • stretchable plastic is packaged as a coil wrapped around a cylindrical cardboard or plastic mandrel.
  • the problem is to be able to unroll the film in order to arrange it around the elements to be palletized, taking into account the characteristics film stretch.
  • the means used have not been satisfactory.
  • the operator has no means or special devices allowing it to film the charge correctly, that is to say to arrange the film around the load to be palletized integrating the palette.
  • the operator is obliged to manually enter the film reel, using both hands to grasp the ends of the support mandrel on which is rolled up the film.
  • Patent FR 2,588,840 discloses a manual unwinding device of reel of stretch film for wrapping.
  • this device includes a bow made of two L-shaped elements made of tube of complementary section so that one of the branches of one elements slide freely in one of the branches of the other element to form a telescopic core.
  • a handle is integral with one of the elements being arranged coaxially to the axis of rotation of the coil film mounted between the two opposite parallel horizontal branches of the two telescopic elements.
  • the device is equipped with braking means constituted by a nut secured to a clamping piece crossing the branch horizontal of one of the elements to be screwed into a barrel secured to the horizontal branch of the other element. The braking of the coil is therefore obtained by acting more or less on the tightening nut.
  • the object of the invention is to remedy these drawbacks, simple, safe, efficient and rational way.
  • the problem which the invention proposes to solve is to be able easily unwind stretch plastic film and control its stretchability by a braking action during the unwinding operation as such corresponding to the filming of the charge with the possibility of canceling at anytime and instantly the braking action.
  • the plastic film used is advantageously of the type of those which are previously stretched before use, released, then wound on the support mandrel.
  • Another problem which the invention proposes to solve is to ability to change film reel without disrupting braking force previously determined.
  • each litter can receive, freely rotation, a conical tip capable of cooperating with the ends cores.
  • the two end caps are strictly identical.
  • the stretch film designated as a whole by (F) is packaged on a reel by being wrapped around a mandrel cylindrical support (1) made of cardboard, plastic or other material.
  • the unwinding device comprises two tips identical (2 and 3) arranged to receive two by two free rotation the support mandrel (1).
  • each of the end pieces (2 and 3) is established at from a plate (2a - 3a) having a circular centering surface (2b - 3b) for the free engagement of the ends of the support mandrel (1).
  • the end pieces (2 and 3) are, on the one hand, connected by a element (4) acting as a grip handle and, on the other hand, subject to means capable of creating an adjustable pressure force for brake the support mandrel (1) concomitantly.
  • each of the plates (2a and 3a) has, on the same side that the circular centering surfaces (2b and 3b) and, in an offset manner, relative to the latter, a tubular sheath (2c, 3c) established perpendicular to the corresponding plate (2a - 3a) to be located in a plane parallel to the generators of the support mandrel (1) after engagement on each of the circular spans (2b, 3b).
  • Scabbards tubular (2c, 3c) are formed perpendicularly and projecting from the plate (2a and 3a) on the same side as the circular centering surfaces (2b and 3b).
  • Each of the sleeves (2c, 3c) has an internal collar (2d, 3d) acting as a stop and delimiting two separate recesses (2e, 2f and 3e, 3f).
  • the ends of the support mandrel (1) cooperate in support with frustoconical bearing surfaces (8) freely mounted in rotation at each of the plates (2a) and (3a).
  • the two tips (2 and 3) are strictly identical, so that after mounting at each of the two ends of the support mandrel (1), the sleeves (2c and 3c) are arranged in gaze and in coaxial alignment.
  • the sleeves (2c and 3c) are established at a previously determined distance from the spans centering (2b and 3b) to allow enough film to be wound up stretchable (F) around the support mandrel (1) depending on the quantities of film required, according to the standards in force.
  • the element (4) which acts as a grip handle is constituted by a tube freely engaged and centered in the facing bores (2nd and 3rd) scabbards (2c and 3c).
  • This handle (4) is supported for example on only the stop (2d), to allow a relative linear displacement between said handle and the sheaths.
  • the handle (4) is indexed rotating in each of the sleeves by any known and appropriate means.
  • the rod (5) is freely engaged in the tubular sleeves (2c and 3c) and the element of handle (4).
  • the rod (5) is engaged and centered through an opening (2d1) formed in the thickness of the stop (2d) to overflow in the recess (3f) of the opposite sleeve (3c) after having crossed a opening (3d1) of the other stop (2d).
  • One of the ends of the rod (5), located on the side of the sheath (2c), has a head (Sa) cooperating in support against the stop collar (2d), said head (5a) being located in the bore (2f) of the sheath (2c).
  • the rod (5) has a threaded seat (5b) for mounting the element (6) in the form of a head threaded.
  • the head (6) is screwed onto the bearing surface (5b) against the member elastic (7), for example in the form of a spring housed in the recess (3f) of the sheath (3c) and pressing against the stop (3d).
  • the head (6) is engaged freely in the recess (3f) of the sleeve (3c).
  • the end caps (2 and 3) and their constituent elements are advantageously obtained by injection of a plastic material.
  • the use of the device is particularly simple and effective, being given that the operator can grasp it with one hand by means of the handle (4) located parallel to the film generators with the possibility cancel the braking at any time by simply pressing the head (6).
