Definitions

  • the invention relates to an apparatus which is easy to manufacture and low-cost and is therefore also within the price range of small and medium-size firms, said apparatus allowing the production of reels of extendable film prestretched longitudinally and of any weight, using a conventional reel of extendable film which is not difficult to procure, which has a large degree of autonomy and which has a cost which is overall much less than that of the reels of prestretched extendable film which can be obtained from it and are otherwise acquired already ready for use.
  • the apparatus comprises a container with a cover which is entirely or partly transparent, inside which the means for rotatably supporting the reel of extendable film as well as the prestretching rollers and the spindle for storing the prestretched film are arranged, these means being all operated by a centralized drive unit. Easy means are envisaged for programming the apparatus for the production of reels of prestretched film with the capacity and with the weight required in each case.
  • the apparatus comprises a container 1 which is made entirely of metal or with a metal frame and with cushioning elements made of any material, which rests on the ground with anti-vibration feet 2, which is open upwards and is closed by a cover 3 which is preferably made at least partly of transparent material, which is hinged for example at 103 on one end of the said container 1 and is provided at the other end with a gripping handle 203 for raising and lowering.
  • the hinging pivot 103 may be designed so that the cover 3 may be easily removed in order to facilitate the apparatus loading operations and any maintenance operations.
  • the cover 3 When, on the other hand, the cover 3 is in the position for closing the container 1, it is envisaged that the said cover activates a safety microswitch 4 which automatically stops the operation of the apparatus if the said cover is raised during a working cycle of the said apparatus in question.
  • the container 1 is provided internally with means for rotatably supporting about its horizontal axis the reel B supplying the extendable film, these means consisting for example of a pair of parallel and idle rollers 5 which are positioned on the bottom of the container 1 and parallel to the said hinging pivot 103 and on which the said reel of film B is rested along its generatrix, as shown in Figure 2.
  • Special means, not shown, are envisaged for facilitating positioning, on the idle rollers 5 inside the container 1, of the reel B which may have a considerable weight.
  • the container 1 has dimensions such that it is able to accommodate internally reels B for example with a diameter of 250-450 mm. Purely by way of a non-limiting example, the container 1 may have the following dimensions: width about 800-1000 mm, height about 500 mm, depth about 700 mm.
  • the sidewalls 101 of the container 1 rotatably support a shaft 6 which is keyed to the slow output of a gearmotor 7 which may be bracket-mounted on the outside of a said sidewall 101 and on which a rubber-coated roller 108 is keyed and which has, keyed on one end, a small-diameter gearwheel 9 which meshes with a larger-diameter gearwheel 10 keyed onto the end of a rubber-coated roller 8 parallel to the roller 108 and rotatably supported by a torque shaft 11 which connects together a pair of parallel arms 12 mounted with the possibility of freely pivoting on the said shaft 6.
  • a gearmotor 7 which may be bracket-mounted on the outside of a said sidewall 101 and on which a rubber-coated roller 108 is keyed and which has, keyed on one end, a small-diameter gearwheel 9 which meshes with a larger-diameter gearwheel 10 keyed onto the end of a rubber-coated roller 8 parallel to
  • the gearwheels 9 and 10 may be arranged inside a special casing or inside a lateral cavity of the container 1 so that they are protected and may be lubricated with suitable means and so that, if necessary, they may be replaced if it is required to modify the relative rotational ratio of the rubber-coated rollers 8 and 108.
  • the rubber-coated roller 108 rotates in the direction F1 opposite to the direction F2 of rotation of the rubber-coated roller 8 and at a higher speed which is determined by the ratio between the diameters of the gearwheels 9 and 10.
  • the said rubber-coated roller 8 rests tangentially by means of gravity on the reel B of film positioned on the support rollers 5 and also causes rotation of this reel about its axis, in the direction F3 and with the speed necessary for unwinding from the latter the film Z which is conveyed around the top half of the rubber-coated roller 8 and then around the bottom half of the rubber-coated roller 108, so that when passing from one roller to the other roller, the said film undergoes the desired longitudinal prestretching action.
  • Special means are envisaged for keeping the roller 8 temporarily in the raised position when it is required to position a new reel B of film on the support rollers 5.
  • These means may, for example, envisage that the torque shaft 11 projects with one end from a sidewall 101 of the container 1, through a curved slit 13 provided on this sidewall and having its centre of curvature on the drive shaft 6 and this same projecting end of the shaft 11 may be easily kept in the raised position as shown in Figure 1, by means of a simple latch 14 mounted externally on the said sidewall 101 which has the eyelet 13. After mounting the reel B on the rollers 5, the latch 14 is raised so as to free the pivoting structure 11, 12 so that the rubber-coated roller 8 comes into contact with the said reel B, as shown in Figure 2. It can be easily understood how, from the position of the shaft 11 inside the eyelet 13, it is possible to determine from outside the container 1 the state of the supply reel B.
  • the end of the prestretched film Z which leaves the faster rubber-coated roller 108 is fixed onto a tubular core A - for example made of cardboard - which is supplied in a suitable quantity with the apparatus in question.
  • the core A is keyed onto a spindle 15 which with its ends is removably supported by a pair of parallel pivoting arms 16 keyed onto a torque shaft 17 which is supported rotatably by the sidewalls 101 of the container 1, all of which being arranged so that the said core A tends to remain in contact by means of gravity with the rubber-coated roller 108.
  • This contact condition which is particularly useful during the initial stage of the cycle when the core A is empty and light, may be ensured by a special ballast weight incorporated in or associated with the spindle 15 or with the use of special resilient means, not shown in that they may be easily deduced by persons skilled in the art.
  • a special ballast weight incorporated in or associated with the spindle 15 or with the use of special resilient means, not shown in that they may be easily deduced by persons skilled in the art.
  • the cover 3 is opened, the film Z is cut along an accessible section, for example along the section situated between the rollers 8, 108 and then the pivoting structure 16 is rotated upwards, against the stop 18, in order to remove the spindle 15 with the associated reel B2, following which the said spindle 15 may be fitted with a new cardboard core and may be repositioned on the arms 16 for the repetition of a new working cycle.
  • the apparatus With the apparatus it is possible to produce reels of prestretched film of any desired weight, these involving partial unwinding of extendable film from the supply reel B.
  • the apparatus has, associated therewith in any suitable position also different from that shown in Figure 1, a small electric control panel 19 which comprises, for example, an activation control device 20, a stop control device 21 and a timer 22 by means of which it is possible to select the activity time of the apparatus and consequently the quantity of prestretched film stored on the reel A.
  • the rotating selector of the timer 22 may show, around it, the weight in kilograms of the film which may be stored on the tubular core A.
  • Special signalling means may be envisaged to indicate when the apparatus has produced the reel of prestretched film of predefined weight, after the timer 22 has stopped the gearmotor 7.
  • a pointer 23 may be fixed onto one end of the torque shaft 17, projecting from a sidewall 101 of the container 1, said pointer moving along a graduated scale provided on the outer side of the said sidewall, in order to indicate the weight or the diameter of the reel B2 of prestretched film stored on the core A.
  • the cover 3 could be designed as a kind of bell, raising of which would provide better access to the various components of the apparatus, both in order to facilitate arrangement in position of a new reel B, and for removal of the reel B2 of prestretched film produced in each case.
