Definitions

  • the present invention relates to ring machines for wrapping loads which are usually palletized, with stretch film, so as to firmly fix the said loads on the support pallet and impart to the whole assembly a rigid condition suitable for transportation and storage.
  • the carriage which supports the reel of stretch film, the rollers for pre-stretching the film unwound from the reel and usually a jockey device with means for retroactive control of the movement imparted to the said pre-stretching rollers travels together with or on a horizontal, round, annular structure which is fastened to a support structure via raising and lowering means and in the centre of which the load to be wrapped with helical turns of the said pre-stretch film is positioned.
  • the front end of the wrapping film is initially retained by a gripper device with associated cutting means, which may be arranged in a fixed position, on the side of the load or which may be associated with the structure which supports the ring.
  • a gripper device with associated cutting means which may be arranged in a fixed position, on the side of the load or which may be associated with the structure which supports the ring.
  • the motor of the pre-stretching unit and the safety devices situated on the rotating carriage are connected to a fixed power supply and control panel by means of a slip ring, for example with a plurality of brushes associated with the said carriage and cooperating with corresponding annular electrically conductive tracks which are mounted with conventional electrical insulation coaxially on the said ring when the said carriage moves along it.
  • the slip ring In order to simplify the fluid-tight design of the slip ring, in some cases the latter is made with small dimensions and is arranged so as to be coaxial with the ring and at a height higher than that of the maximum vertical travel of this component on the cross-beam of the gantry structure with the means for guiding and raising/lowering the said ring, and the small movable element of the slip ring is connected to the carriage with the pre-stretching rollers and with the reel, by means of electric wires guided in an arm in the form of an overturned L, the vertical branch of which has a telescopic form.
  • an electric generator is mounted on the carriage with the pre-stretching rollers or on an oppositely arranged carriage which also performs dynamic balancing functions. Said generator is activated with the rotation of the carriage and forms a buffer power supply for an electric accumulator, so as to provide the electric power necessary for activation of the motor for the pre-stretching rollers without any external connection, also because the entire control and operating logic is mounted on the moving element.
  • the invention intends to overcome the drawbacks of the prior art mentioned above with a ring machine able to operate at an average speed of about 80 rpm and also higher, to use reels of film with a large diameter and therefore a high autonomy and to subject the film to a first pre-stretching step, a subsequent rest (elastic memory return) step and a second pre-stretching (re-stretching) step, with overall elongation of the film equal to about 300% and also more. It has been possible to achieve these important results with the followed proposed solution.
  • the large reel of film, together with the first motor-driven pre-stretching rollers, are arranged on the raising/lowering frame which supports the ring and therefore are in a static position, so that their weight does not pose a problem.
  • the ring is mounted rotatably on the said raising/lowering frame and is made to rotate by a motor which is arranged statically on the said raising/lowering frame.
  • the ring has, mounted thereon, a plurality of vertical rollers which are partly rubberized and partly smooth and are directed downwards, the rubberized rollers among them being connected together by means of a chain or other suitable means, with associated pinions and with an independent drive system, similar to that for rotation of the ring, all the said rollers being driven in a suitable direction and at a suitable speed.
  • a pair of rubberized rollers is provided, these also being driven by the said synchronization chain, but with a ratio such that at least one of these rollers rotates at a peripheral speed higher than that of the upstream roller.
  • the film unwound from the reel is pre-stretched by the said pair of first static pre-stretching rollers, is deposited outside the said rollers supported by the ring, exits from the said pair of second pre-stretching rollers supported by the said ring and reaches a support gripper arranged in a known manner on the side of the load to be wrapped.
  • the ring In order to wrap the palletized load, the ring is made to rotate and with each revolution wraps the said load with a turn of film which has been pre-stretched by the said two pairs of pre-stretching rollers. Since the diameter of the palletized load to be wrapped is always much less than that of the ring of the machine, during rotation of this ring around the load to be wrapped, the film accumulates on the rollers of the said ring and may remain on the latter for the time necessary for recovery of its elastic memory such that it may undergo the final second pre-stretching operation before wrapping of the load, so as to reach the overall stretching percentages mentioned above.
  • the film collecting rollers situated on the rotating ring of the machine rotate at a speed which is controlled by the motor in the static position and which depends on the shape and on other requirements of the palletized load to be wrapped and which, during rotation of the ring, may vary automatically so as to keep at predetermined values the tension of the film during the final load wrapping step.
  • This adjustment may be performed automatically by means of software which takes into account the characteristics, the shape and the size of the load, these being entered in each case into the program manually and/or using autodidactic means.
  • the machine comprises a robust gantry structure 1 with a base 101 which is designed for stable fixing on the ground and which has, sliding on its uprights 201 in a vertically guided manner, controlled by means of a raising/lowering drive system which has not been shown in that it is known, the wide transverse side 102 of a quadrangular and horizontal frame 2 which, for example, projects in cantilevered fashion from one side of the structure 1 and which, by means of horizontal-axis pulleys 3 and vertical-axis pulleys 4, rotatably supports underneath it a ring 5 which is also horizontal and in the centre of which and underneath which the load C to be wrapped is positioned, said load, as shown in the example of Figure 2, being moved in the direction of the arrows A by special motor-driven rollerways, not shown in that they are also of a known type.
  • the ring 5 has on its outer side a groove 105 inside which at least one belt 6 of the reinforced and closed loop type is seated, said belt embracing this ring substantially over the entire circumference, except for a small section along the cross-beam 102 of the frame, where the said belt follows a U-shaped path as a result of being deflected over a pair of pulleys 7 which are supported freely rotatably by the said cross-beam 102 and a pulley 8 which also has a vertical axis and is keyed onto the shaft of an electric motor 9, which is preferably of the type with electronic speed and phase control, for example of the brushless type, mounted on a bracket which is also supported by the cross-beam 102.
  • an electric motor 9 which is preferably of the type with electronic speed and phase control, for example of the brushless type, mounted on a bracket which is also supported by the cross-beam 102.
  • the rollers 10 are rubberized and have the same diameter, for example about 90 mm, while the rollers 11 are made of steel, are smooth and have a diameter the same as or less than that of the said rubberized rollers.
  • the rollers 10 and 11 are arranged alternately with each other so that a rubberized roller is followed by a smooth roller and so on.
  • the smooth rollers 11 are idle, while the rubberized rollers are driven so as to rotate at the same speed and in the same direction F1 as the direction F of rotation of the ring 5.
  • the top end of the shafts of the rollers 10, as also shown in detail in Figure 4 have, keyed onto them, pinions 13 on which a chain 14 is driven, said chain circumscribing said pinions and being kept suitably tensioned by a tensioning device described further below.
  • the ring 5 has internally a lug 305 which is larger than the lugs 205 and which rotatably supports the shafts of a pair of rubberized rollers 15, 115 which are vertical and close to each other and which, for example, have characteristics the same as those of the rollers 10, the shafts of these rollers having, keyed thereon, pinions 16, 116 with a different number of teeth, on which the said chain 14 is driven so that the roller 115 rotates in the same direction F1 as the rollers 10, the roller 15 rotates in the opposite direction and the roller 115 rotates at a speed greater than that of the roller 15 (see below).
  • 17 denotes the idle and adjustable pinion which ensures that the chain 14 has the correct longitudinal tension.
  • the pinion 16 is, for example, identical to the pinions 13 so that the rubberized roller 15 rotates at the same speed as the rubberized rollers 10.
  • the rubberized rollers 10 finally have, keyed onto their shafts, pairs of pulleys 18 on which corresponding pairs of elastic belts 19 are driven externally, said belts forming a closed loop and also being driven on pairs of idle pulleys 20 which are situated on the ring 5 along the shafts of the smooth rollers 11, so that the rotation performed by the said belts is as far as possible similar to a circle (see below).
  • the pairs of belts 19 follow a U-shaped path as a result of being deflected over two pairs of pulleys 21 which are supported idly by the said cross-beam 102 and as a result of passing over a driving pulley 22 keyed onto the shaft of an electric motor 23 with speed and phase control, for example of the brushless type, which is also fixed onto the said cross-beam 102.
  • the pairs of elastic belts 19 are made to rotate in the same direction F of rotation as the ring 5 and at a speed such that the rubberized rollers 10 rotate at the correct speed in the direction of the arrow F1.
  • the cross-beam 102 means for supporting a reel 24 of stretch film and for the controlled unwinding therefrom of the film 124 are mounted together with at least one pair of rubberized vertical rollers 25, 125 of the known type, with an associated drive system 26, for performing longitudinal pre-stretching of the film 124 in accordance with known parameters.
  • the pre-stretched film leaving the first pre-stretching rollers 25, 125 is deposited on the rollers 10 and 11 in the direction indicated by the arrow F, until it reaches the last smooth roller 11, after which it is driven along a winding path between the last pre-stretching rollers 15, 115 and is finally secured to a moving element 27 of the known type situated alongside the path of the palletized load C and fixed for example on the side of the rollerway for conveying the said load or fixed for example to one of the uprights 201 of the gantry structure 1.
  • This moving element 27 comprises a gripper for retaining the film, comprises means for fixing the tail end of the film onto the wound material and cutting means for separating the said tail end of one turn from the new front end of the film which is retained by the said gripper for the following working cycle.
  • the pre-stretched film which has been stored on the rollers 10 and 11 of the rotating ring 5, 12 is kept with the width which it has when leaving the first pre-stretching rollers as a result of transverse gripping with the rubberized rollers 10 and, remaining stationary on the said rollers 10 and 11, gradually reacquires elastic memory so that it may undergo a final pre-stretching operation by the last rollers 15, 115 when the machine is started up.
  • the rubberized rollers 10 are made to rotate in the direction of the arrow F1 at a speed such as to take up, with or without correct longitudinal tensioning, the pre-stretched film leaving the pre-stretching roller 125 and such that film leaves the final pre-stretching rollers 15, 115, further stretched in the longitudinal direction, in an amount and with the longitudinal tension necessary for wrapping the load C.
  • the motor 23 may rotate at a constant speed or at a variable speed, so as to produce a variable supply of film from the final pre-stretching rollers 15, 115, depending on the characteristics and/or the shape and/or the size of the load to be wrapped.
  • the weight created in an eccentric position on the ring 5 by the final pair of pre-stretching rollers 15, 115 and by any jockey device may be conveniently counterbalanced by a ballast weight 28 situated on an inner lug 305' of the said ring 5, in a position diametrically opposite to the lug 305 with the said rollers 15, 115.
  • the ring assembly 5 is able to rotate at speeds much higher than those of the prior art and even as high as about 80 rpm and more.
  • the loading cycle of the said machine envisages a preliminary step during which the front end of the film is not fixed to the gripper 27 but is temporarily fixed to the roller 115, while the motor 23 is made to rotate at a speed such that the rollers 10 and 11 do not rotate about their axis, with the sole aim of accumulating on these rollers a suitable amount of pre-stretched film from the first pair of rollers 25, 125 so that this film has the time to rest and reacquire sufficient elastic memory for the final re-stretching step. Subsequently the front end of the film will be fixed to the gripper 27 and the machine will be ready to start operation.
  • Wrapping of the load is completed with the known steps of raising and lowering the frame 2, so that the palletized load is wrapped by one or more helically wound turns of film which are partially superimposed on each other.
  • the film will be gripped again by the gripping, cutting and fixing unit 27 and the wrapped load may be removed and replaced by a new load to be wrapped.
  • the final pre-stretching rollers 15, 115 could obtain their driving movement from the closest of the rubberized rollers or from a dedicated pinion, via any suitable positive drive transmission.
  • the idle rollers 11 may be rubberized so as to help maintain the transverse dimensions of the pre-stretched film.
  • the rollers 10 and 11 may be designed to support and drive the external belts 29 or a single band or web, so as to form a continuous-surface conveyor which is made of suitable material with a suitable coefficient of friction in relation to the film and on which the said film rests and is thus prevented from performing both transverse and longitudinal contracting movements.
  • the rings 5 and 12 may be interconnected also by means of internal cross-beams in the form of a trellis.
  • the scope of the invention includes also the solution whereby the film is subjected to a single pre-stretching action by the initial rollers 25, 125 or by only the final rollers 15, 115, so that there are no problems of contraction while being driven over the aforementioned rollers 10 and 11.
  • the said pre-stretching rollers may be all or partly such that they subject the film to only longitudinal pre-stretching or to both longitudinal pre-stretching and transverse pre-stretching.
