Definitions

  • the rewinding operation as a whole, firstly requires unwinding the wire of added material from the skein and then rewinding said wire to form a plurality of coils, each of the desired diameter and weight; in particular, the weight of the coils obtained starting from a skein varies from 0.5 kg to 30 kg (corresponding to their varying diameters from 100 mm to 350 mm, respectively), according to the needs and demands of the market.
  • Winding lines are known in the prior art which are capable of automatically winding the coil and which comprise three main and distinct machines, i.e., an initial unwinding unit, on which the starting skein to be unwound is positioned, a final winding and unloading unit or machine of the complete coil of rewound wire (also known as a winding machine or winder), and an intermediate unit, named "take-up", which has the dual function of tensioning the wire between the unwinding and winding steps and synchronizing the rotational speed of the motors of the upstream unwinding unit and the downstream winding unit, as well as during the respective acceleration and deceleration ramps.
  • an initial unwinding unit on which the starting skein to be unwound is positioned
  • a final winding and unloading unit or machine of the complete coil of rewound wire also known as a winding machine or winder
  • take-up which has the dual function of tensioning the wire between the unwinding and winding steps and synchronizing the
  • the winding lines of the prior art comprise a loader (or store or storage station, as noted above), which accommodates the flanged reels (or baskets or drums) on which the wire of added material coming from the skein, from which it was unwound, must be immediately rewound;
  • the loader is substantially arranged operationally (and, in general, also physically) upstream of the winding machine to which it supplies the flanged reels, onto which the wire of added material is wound, in an appropriate and cadenced manner.
  • the empty flanged reels (i.e., still free of the rewound or wound wire of added material) are loaded onto the loader each time by the operator, who arranges them, in the quantity required for the winding step, according to a series of vertical stacks in which flanged reels of the same type and diameter (at least in the same stack) are stacked on top of one another.
  • the second drawback suffered by automatic winding machines of the known type is the articulation and complexity of the operations that must be performed to adjust the position of the components of the winding machine - especially on the initial gripper for inserting the wire of added material to be wound and the final gripper for cutting the wound wire of added material - and that, as a result, require the use of operating personnel with non-negligible and not easily found technical expertise.
  • a further drawback that still distinguishes automatic winders of the prior art concerns the presence of a conspicuous number of mechanical components installed in the tools group inevitably provided with various jobs needed to obtain the desired adjustments and useful to make it possible to change the flanged reels to be rewound.
  • the present invention effectively suggests remedying the aforementioned drawbacks of the prior art, represented for instance by documents CN110482316 A and WO2006/114129 A , starting from their awareness.
  • the automatic winding machine of wire of added material of the invention has a better performance than automatic winding machines of known types comparable to it.
  • the second actuation means, associated with the insertion gripper of the tools group, and/or the third actuation means, associated with the cutting gripper of the tools group are distinct from each other and, favorably, each one comprises at least one electric linear actuator electrically connected to a central processing and control unit which manages its actuation in such a way as to vary, by automatic, progressive and continuous adjustment, the distance between the second actuation means, the third actuation means and the winding body (or spindle) as the size of the flanged reels to be subjected to the winding of said wire of added material varies.
  • the format change of the flanged reels to be rewound is compensated more quickly than in the prior art, to the benefit of the operating efficiency of the machine and making it easier to meet the delivery time of the finished product (represented by the flanged reels wound with the wire of added material).
  • the operators are facilitated in the format changes of the flanged reels to be rewound, because they only adjust the position of the insertion gripper and the cutting gripper relative to the winding body automatically, acting directly on the central processing and control unit, at their disposal through a control panel adjacent to the support structure of the automatic winding machine disclosed herein; thus, in the automatic winding machine of the invention, the insertion gripper and the cutting gripper quickly reach the dimensions desired and useful for processing a given format of flanged reels each time.
  • the automatic winding machine (or winder) 1 comprises:
  • the winding body 6 is made integral with the support structure 2 by means of a rotating table 11 from which the winding body 6 itself protrudes frontally and which is placed in rotation around a horizontal axis Z, shown in figure 3 , orthogonally incident the frontal plane identified by the rotating table 11 itself and thus orthogonal to the horizontal axis X.
  • the aforesaid rotating table may be absent so that the winding body (spindle) will be directly coupled to an inner wall of the supporting structure (or frame).
  • the second actuation means 8 and the third actuation means 10 are distinct from each other and each comprises an electric linear actuator (identified more precisely with a respective reference numeral below) electrically connected to a central processing and control unit, not shown on the accompanying figures, which manages its actuation so as to vary, by means of an automatic, progressive and continuous adjustment, the distance between the second actuation means 8, the third actuation means 10 and the winding body 6 when the format of the flanged reels R to be subjected to the winding of said wire of added material F varies.
  • the second actuation means 8 and the third actuation means 10 are side-by-side according to a front view of the support structure 2 of the automatic winding machine 1 of the invention and face a movable (in this case, sliding) opening and closing door 17 useful for allowing or inhibiting access to a main inner compartment 18 of the support structure 2 itself.
  • the insertion gripper 7 is made to slide by the second actuation means 8 along the horizontal direction X and along the vertical direction Y by means of first composite guiding means, indicated by reference numeral 20 as a whole; in turn, the cutting gripper 9 is, again when operationally required by the above needs, made to slide by the third actuation means 10 along the horizontal direction X and along the vertical direction Y' by means of the second composite guiding means, indicated by reference numeral 21 as a whole.
  • the first guide composite means 20 and the second guide composite means 21 are specifically defined on (or associated, integral with, or cooperating with) an outer surface 19a of the longitudinal plate 19, where the outer surface 19a is generally frontal and facing the movable opening and closing door 17.
  • both the first guide composite means 20 and the second guide composite means 21 consist of a vertical mechanical component and a horizontal mechanical component which allow the consequent sliding of the insertion gripper 7 and the cutting gripper 9 along two directions at right angles to each other, in case of necessity due to a change in the size of the flanged reels R to be rewound.
  • the second actuation means 8 comprise a first electric linear actuator 12 configured to move the insertion gripper 7 along the vertical direction Y, and a second electric linear actuator 13 configured to move the insertion gripper 7 along the horizontal direction X.
  • the insertion gripper 7 is first moved in the vertical direction Y by the first electric linear actuator 12 and then in the horizontal direction X by the second electric linear actuator 13.
  • the third actuation means 10 comprise, instead, a third electric linear actuator 14 configured to move the cutting gripper along the vertical direction Y' distinct from the vertical direction Y (and evidently parallel thereto), and a pneumatic linear actuator 15 operatively connected to motorization means, indicated by reference numeral 16 as a whole, and configured to move the cutting gripper along the horizontal direction X, the same along which the insertion gripper 7 is moved.
  • a third electric linear actuator 14 configured to move the cutting gripper along the vertical direction Y' distinct from the vertical direction Y (and evidently parallel thereto)
  • a pneumatic linear actuator 15 operatively connected to motorization means, indicated by reference numeral 16 as a whole, and configured to move the cutting gripper along the horizontal direction X, the same along which the insertion gripper 7 is moved.
  • Each one of the electric linear actuators 12, 13, and 14 is electrically connected to the central processing and control unit by means of an actuation module, not shown in the accompanying figures, contained in an auxiliary box-like body 23 defined in the support structure 2 and accessible by means of a side door 24, as shown in figures 4 and 7 .
  • each electric linear actuator 12, 13, and 14 provided in the automatic winding machine of the invention is any one of the types of electric actuation devices chosen from the group consisting of parallel electric linear actuators, right angle or "L" electric linear actuators, in-line electric linear actuators, linear guide electric linear actuators and/or combinations thereof.
  • FIGS. 1 and 3 show that it preferably comprises a dynamic lane 25 for the translation of flanged reels R to be rewound, having a variable capacity due to being connected to the third actuator means, such as a pneumatic linear actuator 26, contained in the box-like structure 2 and operatively connected to motorization means, not shown in the accompanying figures.
  • the third actuator means such as a pneumatic linear actuator 26, contained in the box-like structure 2 and operatively connected to motorization means, not shown in the accompanying figures.
  • the automatic winding machine 1 also includes an auxiliary gripping and translation gripper, not shown, operatively arranged downstream of the cutting gripper 9 and cooperating with second actuation means, not shown for the sake of simplicity of exposition, adapted to actuate the auxiliary gripper to remove the coils B one by one from the winding body 6.
  • the main gripping and translation gripper and the auxiliary gripper may be the same and thus consist of a single gripping and translation gripper.
  • the automatic winding machine 1 of the present invention comprises an unloading station 27, diagrammatically and generically identified in figure 6 , contained in the part underneath the support structure 2 and, in this case, distinct from the winding body 6, configured to accommodate consecutively one after the other the coils B released from the auxiliary gripping and translation gripper.
  • the unloading station could coincide with the winding body (spindle).
  • first actuator means - associated with the main gripping and translation gripper - and the second actuator means - associated with the auxiliary gripping and translation gripper are distinct and separate from each other but of the same type, electrically connected to the central processing and control unit, and preferably include a pneumatic linear actuator.
  • the localized heat-sealing means 28 are operatively connected to fifth actuation means, indicated as a whole by reference numeral 29, electrically connected to the central processing and control unit, configured to arrange the localized heat-sealing means 28 alternately between a rest position, in which the localized heat-sealing means 28 are moved away from the winding body 6 and are inoperative, and an operating position, in which the localized heat-sealing means are near and close to the winding body 6 and are operated to couple the first end of the wire of added material F stably to each of the flanged reels R which have progressively to be rewound with said wire F from a skein (as noted in part above, having larger diameter and weight than the individual coils B formed at the automatic winding machine 1 of the invention).
  • a skein as noted in part above, having larger diameter and weight than the individual coils B formed at the automatic winding machine 1 of the invention.
  • the localized heat-sealing means 28, although not explicitly illustrated in the accompanying figures, are also arranged at the aforementioned unloading station 27 and are configured to connect by heat a second end, opposite to the first one, of the added material wire F ends to each of the flanged reels R, embedding the second end in each of the flanged reels R.
  • the localized heat-sealing means 28 arranged at the winding body 6 of the tools group 4 stably couples the initial end of the wire of added material F to an outer surface E of the central drum T of each of the flanged reels R yet to be rewound.
  • the localized heat-sealing means 28 arranged at the unloading station 27 stably couple the final end of the wire of added material F to an inner wall P of one of the two side flanges L >1 , L 2 facing and opposing each other, separated by the central drum T, of each of the flanged reels R just recoiled with the wire of added material F to form the corresponding coil B.
  • the ultrasonic generator 31 - a preferred but non-binding solution provided for the localized heat-sealing (or even heat welding) means 28 preferably arranged in the automatic winding machine 1 of the invention - has the advantage of improving the hold of the coupling of the wire of added material F to the various flanged reels R made of plastic material while making it somewhat easy for the operator to remove at least the end of the wire F when the latter is used in the subsequent welding process.
  • the automatic winding machine (or winder) 1 of wire of added material of the invention advantageously allows the initial end of the wire of added material (more properly, of that part of the wire skein intended to be wound to a given flanged reel) to be coupled to a given flanged reel in a more easy, quick, rapid, and convenient manner than automatic winding machines of the prior art.
  • inventions of the automatic winding machine of the invention may provide that only the second actuation means or only the third actuation means comprise at least one electric linear actuator electrically connected to a central processing and control unit which manages its actuation, so as to determine the automatic, progressive and continuous adjustment of the mutual distance between the second actuation means, the third actuation means and the winding body as the size of the flanged reels to be subjected to the winding of said wire of added material varies.
