Definitions
- the present invention relates to a process and a machine for continuously winding, with an automatic cycle, thermoplastic film so as to obtain bobbins of a chosen size and length directly in line with the film production apparatus or starting from large bobbins.
- thermoplastic films obtained by cast-extrusion were collected on winding rollers so as to obtain large bobbins from which bobbins of the chosen size were prepared by rewinding.
- Rewinding machines of the above mentioned type can be used so as to work directly in line with the apparatus for producing the film, which is conveniently cut into bands of the chosen width, using a rewinding machine for each band.
- the process according to the invention comprises the following steps starting from the already-wound bobbin:
- the cycle can be applied to the simultaneous winding of a series of bobbins (generally three) directly in line with the production apparatus; in this case, the steps for winding the various bobbins are staggered, so as to allow the completion of the cycle for each bobbin before a new one begins.
- the cardboard cores that can be used generally have a diameter of 38, 50 and 76 mm; their width is generally between 400 and 530 mm.
- the process according to the invention in addition to allowing the production of small-size bobbins manufactured continuously and with an automatic cycle, allows to exclude any contact of operators with the winding roller and the bobbins during winding, thus reducing the risk of accidents.
- thermoplastic film any kind can be used; in particular, the polyethylene multilayer stretch film used for the packaging of palletized units is wound.
- FIGS. 1 to 3 are respectively a lateral elevation view of the machine (FIG. 1), a plan view (FIG. 2), and a side-view taken along Y (FIG. 3).
- the connecting rod 1 supports the spindle 2 on which the bobbin 3 being wound in contact with the roller 4 is fitted.
- the connecting rod 1 After cutting the film, reaches a vertical position.
- the spindle 2 is braked and locked in its rotary motion by actuating two pneumatic pistons and is disengaged from the connecting rod 1 by opening two other pairs of pneumatic pistons (not shown in the figure).
- the carriage 5 (moved by motors as shown in the figure and provided with a horizontal translational motion by sliding on the guide 10 and a vertical motion on the guide 6 ) is in the standby position below the bobbin 3 when the connecting rod 1 reaches the vertical position and rises, sliding on the guide 6 until the bobbin 3 is placed on the cradle 7 rigidly coupled to the carriage 5 .
- a series of optical sensors (not shown in the figure), arranged below the cradle 7 , indicate the presence of the bobbin 3 in the cradle, thus providing the confirmation for moving on to the next step (the reference positions for the movements along the vertical guide 6 are confirmed by the presence of microswitches 8 , shown in FIG. 3).
- the carriage 5 performs a further upward translational motion, lifting the spindle-bobbin assembly 2 - 3 , releasing it from the linkage 1 , which can thus return to the working position and receive a new cardboard core-spindle assembly so as to start a new winding step.
- the deflation unit 9 (FIG. 3), arranged on the horizontal guide 10 in axial alignment with the spindle 2 , is activated and discharges air from the spindle 2 by acting on the deflation valve.
- the reference positions for the movements along the horizontal guide 10 are determined by microswitches 12 , shown in FIG. 2.
- the carriage 5 engages the microswitch, which provides the clearance signal for the actuation of the connecting rod assembly 13 for supporting the spindle 2 .
- the connecting rod assembly 13 is meant to support the spindle 2 when the bobbin 3 , drawn by the cradle 7 , is extracted fully from said spindle, which would otherwise be supported only by the support 11 .
- the bobbin 3 is unloaded from the cradle 7 ; the optical sensors connected to the cradle, once illuminated, provide the clearance signal for the fall of the cardboard cores onto said cradle.
- the fall of the cardboard cores and the supply of new cardboard cores on the loading assembly 14 are performed by means of pneumatic pistons (not shown).
- the cradle 7 moves upward with the carriage 5 so as to align the axis of the cardboard cores with the axis of the spindle 2 .
- the linkage assembly 13 returns to the position that preceded its opening in order to support the spindle 2 in the step for extracting the bobbin 3 , thus allowing the regular passage of the carriage 5 .
- the arm 16 provided on the loading assembly 15 with the function of supporting the spindle 2 opens; the subsequent descent of the carriage 5 until it returns to the position it had at the beginning of the cycle allows the spindle 2 to be deposited onto the supporting arm 16 .
- the spindle loader 15 is slightly inclined with respect to the winding unit, the spindle 2 can slide toward the inflator assembly 17 .
- the spindle 2 After performing inflation, the spindle 2 continues its descent until it reaches the chain 18 .
