Abstract
Description
- The present invention relates to a winder for winding continuous web material.
- In particular, the present invention is for use in the sector of th paper-converting industry and of industrial machines for working and producing paper or web materials in general, for the formation of reels having significant dimensions and not normally intended for retail.
- As it is known, the formation of such reels is made by means of machines so-called winders, which have a cylindrical body or spool driven into rotation about a horizontal axis and around which a web is wound being unreeled from suitable supply units.
- Two motor-driven guide rollers, located at the bottom of the winder, below the cylindrical body, promote the unwinding of the web from the supply unit and the consequent winding of same web around the cylindrical body.
- Initially, the cylindrical body rests above the motor-driven rollers, with the web being interposed between the latter and the cylindrical body.
- As the dimensions of the reel increase, the thickness of the material, interposed between the motor-driven rollers and cylindrical body for the winding, increases as well and, therefore, the cylindrical body lifts up by vertically sliding along a guide rail.
- The cylindrical body is connected to a bearing structure, typically consisting of arms or rods fitted at the center of the spool and around which the cylindrical body rotates. The cylindrical body or spool is able to rotate by interacting with the motor-driven rollers on which it is in contact, if it is idle, or may be motorized itself.
- The winding of the web about the spool may cause the formation of irregularities onto the reel surface, such as ripples, corrugations or drafts which spoil the web and alter the quality of the same reel.
- With the growing of the winding layers, the anomaly inevitably becomes worse, thereby accentuating the size of the corrugations which propagate over a greater surface of the reel.
- To avoid these irregularities and achieve a reel of desired quality, the state-of-the-art machines are provided with a counteracting element, so-called rider roller, which is made to rest over the reel.
- In base of the contact pressure value between the rider and the reel, there is determined the density, softness and quality of the reel in the course of formation.
- The rider roller, connected to mechanical bearing means, is generally made to rest onto the reel, rotates therewith and, when interferring with irregularities, in particular ovalizzations and effects of resonance of the reel, is subjected to sudden vertical displacements.
- Following this, it begins to oscillate, by jerking on the surface of the reel under formation.
- Owing to said jerks, the counteracting element, upon falling back, exerts kickbacks onto the reel, thereby transmitting vertical forces on the surface thereof which may accentuate the irregularities already present thereon.
- Occasionally, phenomena of resonance may occur between the counteracting element and the same reel.
- To reduce the damping effect of the counteracting element, elastic bearing means have been proposed which are able to control the vertical movement thereof by reducing the intensity of the force transmitted onto the reel surface.
- Although such elastic bearing means are able to lower the energy transmitted by the counteracting element to the reel surface, it has been found that this approach does not solve the problem of the increase of already present anomaly.
- Actually, the bearing means only relieve the weight of the counteracting element without preventing the latter, upon falling back, from transmetting kickbacks, even if of slight intensity, to the reel.
- The object of the present invention is therefore to propose a winder for continuous web material which overcomes the drawbacks of the prior art.
- Accordingly, the object of the present invention is to provide a winder for continuous web material able to form a reel of considerable size, by limiting the formation of irregularities onto the surface of the same reel and avoiding any increase and spread of such anomalies.
- A further object of the present invention is to provide a winder for continuous web material able to form reels without excessive surface irregularities and the occurrence of resonance phenomena during the formation of the reel.
- These and other objects, which will appear more clearly by a reading of the detailed description that follows, are substantially achieved by means of a winder for continuous web material, according to one or more appended claims.
- Further characteristics and advantages will appear more clearly by the detailed description that follows of a preferred but non-exclusive embodiment of a winder for continuous web material, according to the present invention.
- Said description is given herebelow with reference to the attached figures to be considered in an indicative and, therefore, non-limitative purpose. In the drawings:
-
Fig. 1 is schematic side view of a winder for continuous web material according to the present invention, in a first operating step; -
Fig. 2 is a schematic side view of a winder for continuous web material according to the present invention, in a second operating step; -
Fig. 3 is a left front view of the winder for the continuous web material shown inFig. 1 ; and -
Fig. 4 is a right front view of the winder for the continuous web material shown inFig. 1 . - According to the attached drawings,
numeral 1 indicates on the whole a winder for continuous web material. - The
web 2, coming from thesupply unit 3, is wound around a cylindrical body or spool 4 rotating about anaxis 4a being preferably in horizontal position. - Positioned at the bottom of the
winder 1 is at least one motor-drivenroller 5 which facilitates the unwinding of the web from thesupply unit 3. - Shown in the attached
figure 1 are two motor-drivenrollers 5 which cooperate with thecylindrical body 4 to promote the winding ofweb 2 around thecylindrical body 4 for the formation of areel 6 of web material. - The
web 2 slides between the motor-drivenrollers 5 and thecylindrical body 4 being located above therollers 5. - Initially, the
cylindrical body 4 is in contact with the motor-drivenrollers 5, but, as the winding ofweb 2 around the cylindrical body orspool 4 goes on, the diamter ofreel 6 becomes larger and, consequently, the cylindrical body lifts up by sliding along arail 7, as shown inFig. 1 , moving away from the motor-driven rollers. - The
cylindrical body 4 rotates around two opposed, preferablyhorizontal rods 9, each being connected to a respective bearing anddriving mechanism 8, the structure and operation of which will be described herebelow. Thecylindrical body 4 rotates about theaxis 4a merely by the effect of the motor-drivenrollers 5 motion, with which thespool 4 cooperates if it is idle; alternatively, thecylindrical body 4 may be motorized. - Similarly, the lifting of the
cylindrical body 4 along therail 7 may be caused either by the action of the bearing anddriving mechanism 8, connected to the saidopposed rods 9, or it may be simply due to the thickening of theweb 2's layers interposed between thecylindrical body 4 and the motor-drivenrollers 5, as the diameter ofreel 6 increases. - The winder further comprises a
counteracting member 10, preferably made up of a cylindrical roller able to be positioned against the outercircumferential surface 6a ofreel 6 to facilitate th formation thereof. - Preferably, the
counteracting member 10 extends over the whole width ofreel 6 and rotates onto thesurface 6a thereof about ahorizontal axis 10a, parallel to theaxis 4a ofreel 6. - The
counteracting member 10 as well may either idle or motorized, and it rotates at the same peripheral speed asreel 6. - Advantageously, the
counteracting member 10 as well slides vertically along therail 7, being connected to at least one respective bearing anddriving mechanism 8, likewise the one to which theopposed rods 9 sustaining thecylindrical body 4 are connected. - In particular, said bearing and
driving mechanism 8 allows the movement in a single direction of both the countercatingmember 10 and thecylindrical body 4 during the formation of thereel 6. - In other words, and by referring in particular to the counteracting
member 10, during the winding ofreel 6, when thecounteracting member 10 comes across an irregularity ofsurface 6a, it undergoes an upward vertical displacement. The bearing anddriving mechanism 8 retains thecounteracting member 10 in the new lifted up position and prevents it from sliding downwards and coming back in contact with the surface of thereel 6. Owing to further windings ofweb 2, thereel 6 grows progressively in diameter until thesurface 6a thereof meets again thecounteracting member 10. At this point, thecounteracting member 10 abuts again against thesurface 6a ofreel 6 and resumes its function as an element for the control and aid of the winding. -
Such mechanism 8 comprises at least onefree wheel 11 keyed on arotary shaft 12, and means 13 for connection between thecounteracting member 10 and therotary shaft 12 on which eachfree wheel 11 is keyed. - In particular, such connection means 13 comprise a chain meshing with the teeth of a
wheel 15 keyed on therotary shaft 12. Alternatively, the connection means 13 comprise arope 14 which winds up around apulley 15 keyed on theshaft 12. - Shown in the attached figures is a chain and a toothed wheel. Accordingly, for the sake of simplicity, the description that follows will make reference, only by way of example, to these two elements without, however, departing from all general cases.
- Each
free wheel 11 can be associated with abrake 16, being active on aperipheral portion 11a of thefree wheel 11 during the winding ofreel 6. Thebrake 16 is necessary for the operation of thefree wheel 11 as it keeps theperipheral portion 11a of thefree wheel 11 blocked while thecentral portion 11b keyed onshaft 12 rotates with the latter. - The bearing and
driving mechanism 8 further comprises at least onecounterweight 17 connected to said connection means 13 and especially to thechain 14 to ease the vertical sliding of the counteractingmember 10. - The
counterweight 17 may also comprise an actuator for driving forcedly into motion thecounteracting member 10. - Advantageopusly, provision is made for two bearing and
driving mechanisms 8 cooperating with thecounteracting member 10, and two further bearing anddriving mechanisms 8 cooperating with theopposed rods 9. - Each end of the counteracting
member 10 is connected to thechain 14 to which also the counterweight oractuator 17 is engaged via a series of intermediate members consisting oftoothed wheels 15. - Likewise, each
rod 9 is connected to respective connection means 13 which transmit the motion from the rods to thefree wheel 11. In particular, eachrod 9 is connected to arespective chain 14 to which also the counterweight oractuator 17 is engaged via a series of intermediate members consisting oftoothed wheels 15. Thechain 14 is made to mesh with thetoothed wheel 15 keyed on theshaft 12 coaxial with thefree wheel 11. - As the diameter of
reel 6 grows larger, thecylindrical body 4 translates vertically upwards owing either to the increasing dimensions of thereel 6, as previously discussed, or to the effect of the pull ofactuator 17 which drives into motion thechain 14 and, consequently, lifts up thecylindrical body 4. - The sliding of
chain 14 drives into rotation thetoothed wheel 15 keyed on theshaft 12. - The rotation of
shaft 12 is cause also for the rotation of thefree wheel 11, in particular of itscentral portionb 11b directly connected to theshaft 12, while theperipheral part 11a is kept stationary by thebrake 16. - The
free wheel 11 allows the rotation of theshaft 12 only in one direction, by preventing the rotation in opposite direction and, in particular, preventing the rotation in the direction that would allow the descent of thecylindrical body 4. - Once the
reel 6 is wound to the end, the moving down of theopposed rods 9 is allowed by disengaging theperipheral portion 11a of free wheel from thebrake 16, so as to allow the rotation of the shaft in both directions. - Likewise, the counteracting
member 10 is connected to therotary shaft 12 via thechain 14 which engages thetoothed wheel 15 keyed onshaft 12. - When the counteracting
member 10 comes across an irregularity of thesurface 6a ofreel 6, it si pushed upwards. - This drives the
chain 14 into motion and, consequently, causes the rotation of thetoothed wheel 15, ofshaft 12 and thus of thecentral part 11b of thefree wheel 11. - After the rotation, the
free wheel 11 comes to a stop at a new angular position, thereby blocking the counteractingmember 10 in the raised position: the rotation ofshaft 12 in the opposite direction, that is, in the direction that would move again the counteractingmember 10 downwards, is prevented. - The
cylindrical body 4 continues to rotate about theaxis 4a, the web keeps winding up and the reel increases progressively its diameter so that, at a certain point, thesurface 6a ofreel 6 meets again the counteractingmember 10 which starts again to compress thesurface 6a thereby levelling and reducing the irregularities. - Once the
reel 6 has been completely formed, it is withdrawn from thewinder 1. - For repositioning the counteracting
member 10 on the bottom of the machine, in other words, for allowing the downward vertical displacement thereof, thefree wheel 11 is disengaged from thebrake 16 so as to allow the rotation of thefree wheel 11, and thus ofshaft 12, also in the initially prevented direction. - The invention obtains major advantages and the intended objects.
- In fact, because of its interference with irregularities of the surface, the counteracting member is displaced upwards bu does not fall back onto the surface. This avoids the kickbacks that the devices of the prior art exert on the surface of the reel and, therefore, prevents the increment and spread of the anomalies generated during a high speed winding of the web.
- Moreover, by preventing the jerks of the counteracting member onto the reel surface there is avoided any phenomenon of interference, in particular between the counteracting member and the same reel.
