Definitions

the invention relates to a rewinding machine for the production of web reels. More in detail, the invention relates to a rewinding machine of the type comprising:
the invention also relates to a method for the production of reels of web.
Operations concerning winding or rewinding web are required in the sector of non-woven processing, e.g. in the production of reels of semifinished materials intended for the production of sanitary towels, diapers and the like, and also in the production of paper, e.g. for the production of rolls of toilet paper, kitchen paper or similar, for the production of reels for supplying folding machines for the production of napkins, paper handkerchiefs and similar disposable products.
the web production process is continuous and the web is wound on large diameter parent reels. These reels are later unreeled and the web is rewound on smaller diameters reels or rolls.
the web is cut longitudinally and continuously and wound on winding cores, which can be made of cardboard, plastic or other suitable material, the core being fitted and aligned on a winding mandrel.
winding cores which can be made of cardboard, plastic or other suitable material, the core being fitted and aligned on a winding mandrel.
the winding mandrel on which the winding cores are fitted is expandable, e.g.
the various tubular cores - whose reciprocal axial length may be either variable or different - receive corresponding strips of web obtained by longitudinally cutting the web from the parent reel.
the rolls or reels are developed in sequence.
the finished reel is unloaded from the winding cradle, e.g. formed by two winding rollers arranged side by side, and replaced with a new winding mandrel onto which the winding cores were previously secured.
a rewinding machine of this type is described in EP-A-0747308. Another example of rewinding machine of this type is described in EP-A-1070675. Additional examples of peripheral rewinding machine of the start-stop type, i.e. in which the supply of web is temporarily interrupted to replace the completed reel with another winding mandrel, are described in GB-A-2268476, DE-C-3836367, EP-A-0640544.
Object of the invention is to provide a rewinding machine of the aforesaid type in which the rewinding cycle speed can be increased and particularly in which the exchange time, i.e. the time required to replace the finished reel or roll with a new winding mandrel, is reduced.
a rewinding machine of the above mentioned type comprising a pair of lateral flanks, on each of which a corresponding guide defining a closed path is arranged, along which a plurality of said mating centersa are mobily arranged.
the mating centers are arranged on the two flanks so that each mating center carried by one of said flanks corresponds to and is axially aligned with a mating center carried by the other of said flanks.
a system is also provided to drive the mating centers along each of the guides.
a first pair of mating centers engages a reel or roll under formation and a second pair of mating centers engages a new mandrel simultaneously.
the finished reel can be conveyed from the winding cradle to the unloading area and simultaneously the new mandrel can be conveyed from a loading area to the winding cradle by moving the pairs of mating centers along the closed path.
the rewinding machine provides a number of additional advantages. Such advantages include improved control of the reel during the unloading phase and more accurate control of the web cutting phase for forming the trailing end of the finished reel and the leading end of the web to be used for winding a new reel to be formed on the new mandrel.
the finished reel or roll is ejected from the winding cradle, typically defined by a pair of winding cylinders, by pushing and rolling.
the reel is then positioned in an unloading device in a position which is not exactly repeatable at each cycle with consequently possible difficulties in the web cutting phase for starting the winding of the following reel.
each mating center can be carried by a respective carriage which slides on the guide of the corresponding flank.
the path defined by said guides extends from a first mandrel engagement position to a second finished reel unloading position; said winding cradle being arranged between said first and said second position.
the handling system comprises a continuous flexible member onto which the mating centers associated to the respective flanks are secured on each flank.
a drive is provided for moving said flexible member.
Each motor can drive two flexible members.
the movements of the mating centers on the two flanks will be synchronized by means of an appropriate mechanical transmission.
two separate motors can be used and synchronized electronically by means of a control unit, i.e. using an electric axis.
the mating centers can each be equipped with an actuator which controls the movement along the guide with a suitable control for synchronizing the movement of each mating center.
a taker-in is provided to insert the winding mandrels moving from a collection position of the winding mandrels to a release position of the winding mandrels, in correspondence with the position in which the mandrels are engaged by the mating centers.
the taker-in may consist of a pivoting member but might also be made in a different way.
the winding mandrels could be inserted axially, i.e. with a movement parallel to their axis inside a fixed support, such as a cradle or other.
the mandrels can be collected from this location by the mating centers as they move along said closed path.
the taker-in can be equipped with an insertion movement which is not pivoting, e.g. by translating from a mandrel collection position to a mandrel release position.
the winding cylinders can be made so that during the winding phase the axis of the reel or roll (and consequently of the winding mandrel) is always in the same position. This can be obtained in a way which is known per se employing mobile axis winding cylinders with a vertical movement component so that the winding cradle is gradually lowered according to the increased diameter of the reel.
the two flanks can be fixed and the mating centers can be held constantly at the same height for the entire reel winding phase.
flanks will also be vertically mobile and actuator means will be provided to control the upwards and downwards movement of said flanks according to the diameter of the reel. Synchronization means will be advantageously provided for the vertical movement of the flanks also in this case.
the two winding cylinders can be mobile one with respect to the other and can be opened, e.g. one can have a fixed axis and the other a mobile axis according to a horizontal trajectory.
This increases the supporting base of the reel as it gradually increases in diameter during the winding operation.
the axis of the reel will follow a more or less complex trajectory with a movement which has a vertical component and a horizontal component.
the trajectory followed by the axis of the reel changes according to the characteristics of the product (specifically its thickness) and the working conditions of the machine.
the rewinding machine can have only two lower winding cylinders arranged side-by-side, either mobile or fixed as illustrated above, to withhold the reel under formation.
the rewinding machine comprises a third cylinder whose axis is parallel to the first and the second winding cylinder arranged over the winding cradle and mobile to allow for the increased diameter of the reel developing between said first, second and third cylinder.
the third cylinder is carried by a pair of pivoting arms whose fulcrum is in a position which does not interfere with the flanks (which may be mobile) carrying the guides which define the closed path followed by the mating centers.
the third cylinder can be idle or preferably driven with a peripheral speed which is essentially equal to the peripheral speed of the first and the second winding cylinder, it being understood (in a way that is known per se) that the three cylinders can have slightly different peripheral speeds to obtain the required degree of compactness in winding the reels.
a variable number of mating centers can be provided along each of two guides carried by said flanks also according to the type of movement adopted.
the number of mating centers on each side will appropriately be equal to at least three and preferably equal to five.
the machine When the machine is provided with a taker-in for inserting the winding mandrels, it can advantageously present a winding mandrel resting cradle whose geometry corresponds to that of the winding cradle in the initial winding phase. As clearly described in the example of embodiment that follows, this arrangement ensures correct handling without the need for adjustments in the presence of mandrels with variable diameters.
the distribution means can comprise a rotating distributor for each flank arranged inside the path defined by the guide along which the mating centers move and one or more flexible members towards said mating centers.
an electrical distribution box and a pneumatic distribution box can slide along each of said guides; said electrical distribution box and said pneumatic distribution box can be connected by means of flexible members to a distributor arranged inside the path defined by the guides along which the mating centers and said boxes move; and said boxes can be connected to the mating centers via flexible pneumatic and electric connections.
the invention also relates to a method for the production of reels of web wound on winding mandrels in which:
the rewinding machine comprises a fixed structure 1 with two lateral flanks fastened to the base.
the fixed structure 1 carries a pair of winding cylinders 3, 5 whose axes are parallel defining a winding cradle 7 in which the winding mandrels are arranged with one or more cores made of cardboard, plastic or other suitable material fitted upon them.
the cores are fitted and secured on the mandrels by expansion of the mandrels in a way which is known per se in a station outside the rewinding machine.
