Definitions
- the present invention relates to a core feeding method in a rewinding machine for making logs of sheet or web material, for example used for the production of rolls of toilet paper, rolls of all purpose tissue paper for household use, non woven fabric, industrial rolls and the like.
- the invention relates to a rewinding machine that carries out this method.
- Rewinding machines wherein a log is wound that is in contact surface with winding rollers. More precisely, the log is formed starting from a web of paper, continuous or with transversal perforations, which, carried by a first conveyor, is wound partially on an upper winding roller, enters into contact with a lower winding roller and is kept against the two upper and lower winding rollers by a pressure roller.
- the three rollers define a winding zone wherein the log is formed by feeding the web of paper and by dragging it for surface contact.
- the log Normally, in the winding zone the log is formed on a tubular core. Once the log has reached a predetermined diameter, with a control normally on the paper length as wound, the web is cut or torn and the log is pushed away from the winding zone at the side opposite to the introduction zone of the core and, at the same time, a core is put in by a pusher.
- Some rewinding machines at the end of each winding step, provide a blade that cuts transversally the web against the upper winding roller, which has one or more cutting slots with which a retractable blade engages mounted on an adjacent cutting roller.
- the core is brought on a feeding cradle of curved shape located under the upper winding roller, whereby the friction against the upper roller brings it forward up to the contact with the lower winding roller for starting the winding.
- the cradle is formed by a series of curved guides that protrude rearwardly from the lower winding roller and are to it completely integral.
- the lower roller is brought forward or away from the upper roller.
- a different cradle is necessary for each different diameter of the core. This causes stops in the production, an adjusting work and the need of a set of cradles, one for each different diameter of the core.
- the cradle is movable with respect to the support of the lower roller and is capable of lowering or rising towards/away from the upper winding roller.
- the movable portion of the cradle can be displaced from a first position of load of the core to a second position wherein the core contacts the upper roller.
- the cradle In its movement of lowering/rising, the cradle can rotate about a pivot concentric to the lower roller.
- the core moves on the movable portion of the cradle and then on a portion of the cradle that is integral to the lower roller. Furthermore for reaching the winding zone remaining in contact with the upper roller, the core is pushed by the cradle against the upper roller in a resilient way.
- the core is put on the cradle when the movable portion is in lowered position, rolling on a downhill portion of the movable portion up to reaching a peeping stop element.
- a rewinding machine of a web for making a wound log on a core in particular for the production of rolls of toilet paper, rolls of all purpose tissue paper or non woven fabric for household use, industrial rolls and the like, comprises:
- [0026] means for feeding and dragging a web of paper
- a core feeding cradle arranged upstream of the winding zone, the cradle being located beneath the upper winding roller and extending between the means for feeding the core up to the lower winding roller;
- the cradle has a resilient surface for adapting to the passage of the core pushing it against the upper roller.
- the cradle has a curved surface with concavity oriented towards the upper roller.
- the means for lowering/rising the cradle towards/away from the upper winding roller are operatively connected to an arm pivoted to the same support wherein the axle of the lower winding roller rotates.
- the cradle has a fixed portion integral to the lower roller located downstream of the movable portion, the movable portion cooperating with the fixed portion in order to form a single surface of support for the core during winding.
- the movable portion may have a portion downhill and a peeping stop element.
- Means are provided for controlling the means for lowering/rising selectively the movable cradle to a predetermined height with respect to the upper winding roller.
- FIG. 1 shows a cross sectional view of a rewinding machine according to the present invention
- FIGS. from 2 to 5 show four different positions of the tail of the web of the wound log and of the head of the web of the log to be wound, as well as the steps of feeding the log in the core.
- a rewinding machine of a web 1 for making a log 2 a comprises a roller 3 for feeding web 1 and, downstream of it, a winding zone 4 where the log 2 a same is wound.
- Winding zone 4 is formed by an upper winding roller 5 , a lower winding roller 6 and a pressure roller 7 .
- the latter follows the growth of the log 2 a with the task of assuring its continuous contact with the winding rollers 5 and 6 and of controlling the growth of its diameter.
- Counter support roller 8 is provided on which web 1 rests.
- Counter support roller 8 can be driven independently and comprise cutting means 10 that engage with a cutting slit 9 .
- the cutting roller can operate directly on upper roller 5 .
- blade 10 engages with countersupport roller 8 (or with upper roller 5 ) for cutting web 1 , thus creating a tail end 1 a of the previous log 2 a and a head end 1 b of a log to be formed.
- the winding was started by a core 20 a , which had been put into zone 4 by a chain conveyor 22 . Furthermore a core 20 b is ready for being a winding support for a log to be wound starting from the head portion 1 b of web 1 .
- upstream of zone 4 a cradle is provided 21 , 26 for feeding a core 20 b .
- Cradle 21 , 26 is located beneath upper winding roller 5 and extends between the chain conveyor 22 of the core up to lower winding roller 6 .
- Cradle portion 21 is movable and is capable of lowering or rising towards/away from upper winding roller 5 .
- core 20 b is brought by a fixed portion 26 , to which the terminal portion 21 a of movable portion 21 is adjacent.
- core 20 b is put on movable portion 21 when it is in a lowered position, rolling on a downhill starting portion 21 b up to a peeping stop 27 . Then, as shown in FIG. 2, core 20 b approaches upper roller 5 without contacting it.
- Peeping stop element 27 can be a harmonic steel blade, as that shown in the figure, or it can be a finger hinged to movable portion 21 and yielding by means of the action of a spring at the passage of the core (FIG. 3).
- core 20 b is preglued along at least a line, whereby it quickly catches end 1 b at the passage from the positions of FIGS. 3 and 4, moving on movable portion 21 .
- Both movable portion 21 and fixed portion 26 have a curved surface with concavity oriented towards the upper roller.
- This surface in a way not shown, may be resilient.
- it may have a surface coated of spongy material, or a plate suspended on springs, or a surface formed by a belt stretched between two ends.
- core 20 b reaches the winding zone 4 previously abandoned by log 2 a .
- a log 2 b starts to be wound for rotation of rollers 5 , 6 and 7 , as indicated by the relative arrows.
- a core 20 c is put in by chain conveyor 22 after that the movable portion 21 of the cradle, integrally to arm 23 , has been lowered by connecting rod 25 by means of driven shaft 24 .
- the new core 20 c rolls on the short downhill portion 21 b and reaches peeping stop element 27 .
- lower roller 6 is displaced in the direction of arrow 28 , substantially in direction towards/away from the centre of lower roller 5 .
- both fixed portion 26 and movable portion 21 along with arm 23 , follow integrally lower roller 6 .
- the winding steps of web 1 for making a log 2 a can provide the cut of the paper upstream of upper winding roller 5 (FIG. 1).
- the web of paper 1 is fed in the winding zone 4 about core 20 a up to a predetermined development upstream of the feeding roller 3 .
- countersupport roller 8 at cutting slot 9 with transversal blade of cutting roller 10 cut or tear web 1 separating the tail end 1 a from head end 1 b . From this moment the various steps are then successively carried out of bringing head end 1 b towards the winding zone, not described in detail, but shown in EP1016608.
- the contact of core 20 b same against upper winding roller 5 can cause the tearing of the paper 1 along a line of transversal perforation 31 of the paper that is located between core 20 b and winding zone 4 .
- a step is provided of stretching the web between the core and the winding zone.
- This stretching can be carried out by accelerating the abandonment movement of already wound log 2 a , for example, according to the prior art, with interposition between already wound log 2 a and the lower roller of a fixed tray 32 (FIGS. 3 , 4 , 5 ), whereby log 2 a runs quickly away on tray 32 .
- the tearing step is carried out by acceleration of pressure roller 7 with respect to lower roller 6 .
- FIGS. 1 - 5 The preferred embodiment of the invention of FIGS. 1 - 5 has been shown only through a cross sectional view in five operative positions and not with a top plan view or an elevational view, that are not necessary since obvious for a man of the art.
- rollers 3 , 8 , 10 , 5 , 6 and 7 and driven shaft 24 would be seen that extend for all the maximum length of log 2 a and of core 20 a , with ends that engage with support walls by means of bearings as well as drive and transmission elements.
- Cradle 21 , 26 would be seen as a plurality of arms 23 , 26 arranged some centimeters from one another and connected to support 29 wherein the axle rotates of lower roller 6 .
