Abstract
A rewinder for winding a web to produce a rolled product. The rewinder includes a web transfer device that is used for conveying the web. The web transfer device communicates with a core in order to wind the web via surface winding. At least one pair of rotationally driven end chucks are located proximate to the web transfer device. The end chucks engage the core and the web is wound onto the core via center winding by the rotating end chucks. Also, the web is wound onto the core to form a rolled product by a combination of the center winding and the surface winding.
Description




BACKGROUND




Web “winders” are typically used to form large rolls of wound paper known as parent rolls. From the parent rolls, “rewinders” are employed in order to wind the web into a rolled product. The rolled product is then cut at designated lengths into the final product. Final products typically created by these machines and processes are toilet tissue rolls, paper toweling rolls, paper rolls, and the like.




There are essentially two types of techniques known in the art for performing the step of rewinding, that is winding the web from a parent roll into a rolled product. The first of these techniques is known as center winding. In center winding, a core is rotated in order to wind a web into a roll on the core. Typically, this core is mounted on a mandrel that rotates at high speeds at the beginning of a winding cycle and then slows down as the size of the rolled product being wound increases. Center winders work well when the web that is being wound has a printed, textured, or slippery surface. Also, center winders are very useful in producing softer rolled products.




The other type of technique used in winding a web to form a rolled product is known as surface winding. In surface winding, the web is wound onto the core via contact with belts and/or rotating rolls. A nip is typically formed between two or more co-acting belt systems. The belt systems typically travel in opposite directions at different speeds. The reason for having different speeds lies in the fact that a core that is being driven by the belts will advance in the direction of the faster moving belt. Usually, these belts are divergent so that the rolled product that is being built up on the core will have enough space to be produced, and will be able to contact the two diverging belts. Typically in surface winding, the core and the web that is wound around the core are driven by belts and/or rotating rolls that operate at approximately the same speed as the web speed.




In order to assist transfer of the web onto the core, it is known in the prior art to apply an uninterrupted line of glue or adhesive onto the core. The web will therefore contact this adhesive and adhere to the core as it is being wound onto the core.




In the prior art, a “winder” or reel is typically known as a device that performs the very first wind of that web, generally forming what is known as a parent roll. A rewinder, on the other hand, is a device that winds the web from the parent roll onto a roll that is essentially the finished product. However, the prior art is not consistent in designating what is and is not a winder or rewinder. For instance, rewinders are sometimes called winders, and winders are sometimes referred to as rewinders. It is to be understood that as used in the present application, the words “winder” and “rewinder” are interchangeable with one another in assessing the scope of the claims. In other words, the claims cover both “winders” and “rewinders” even though only one of these words may be used in the claims.




The prior art lacks a rewinder capable of performing both center winding and surface winding in order to take advantage of the positive attributes both processes enjoy.




SUMMARY




Objects and advantages of the invention will be set forth in part in the following description, or may be obvious from the description, or may be learned from practice of the invention.




The present application discloses a rewinder for winding a web to produce a rolled product. In one embodiment, the rewinder includes a web transfer device that conveys the web. The web transfer device communicates with a core in order to wind the web onto the core via surface winding. At least one pair of rotationally driven end chucks are also provided. The end chucks are located proximate to the web transfer device. The end chucks engage the core and the web is wound onto the core via center winding by the rotating end chucks. Also, the web is wound onto the core to form a rolled product by combination of the center winding and surface winding.




Another embodiment of the present invention includes a rewinder as discussed above which further has an applicator located proximate to the web transfer device for applying adhesive to the web.




In addition, the present invention may also have an embodiment as immediately discussed which further has a tension roll located upstream from the applicator. The tension roll engages the web and applies tension to the web.




Also disclosed according to the present invention, is an embodiment of a rewinder as originally discussed which further has an odd set of a plurality of rotationally driven end chucks. This rewinder also has an even set of a plurality of rotationally driven end chucks. The odd and even sets of end chucks are staggered such that when one pair of the odd set of end chucks finishes winding the web to produce a rolled product at the same time as one pair of the even set of end chucks begins winding the web to form another rolled product.




Also disclosed according to the present invention is another embodiment of a rewinder for winding a web to produce a rolled product. This rewinder has a web transfer device that is used for conveying the web. The web transfer device communicates with a core in order to wind the web onto the core. Also included is an air blast device that is located proximate to the web transfer device. The device delivers an air blast that aids in transferring the web from the web transfer device to the core. Further, an applicator is located upstream from the air blast device and is used for applying adhesive to the web. Also, a tension roll is located upstream from the applicator. The tension roll engages the web and applies tension to the web. Also, as is known in the art, the tension roll may sever the web on a part line for transfer from one wound log to the next.




Also disclosed is an embodiment of the rewinder as immediately discussed which further has an odd set of a plurality of rotationally driven end chucks. This rewinder also has an even set of a plurality of rotationally driven end chucks. The odd and even sets of end chucks are staggered such that when one pair of the odd set of end chucks finishes winding the web to produce a rolled product, one pair of the even set of end chucks begins winding the web to form another rolled product.




A still further embodiment of the present invention includes a rewinder as discussed above where adhesive is applied by the applicator to the leading edge of the web. This is facilitated in order to assist in the transfer of the web from the web transfer device onto the core. Another embodiment exists where adhesive is applied by the applicator to the trailing edge of the web in order to fix the trailing edge of the web onto the web that is wound on the core.




Yet another embodiment of the present invention includes a rewinder that is used for winding a web to produce a rolled product. This rewinder has a web transfer device that is used for conveying the web. An odd set of a plurality of rotationally driven end chucks are present. The odd set is located proximate to the web transfer device for engaging a core onto which the web is wound. An even set of a plurality of rotationally driven end chucks are also present. The even set is located proximate to the web transfer device and is used for engaging a core onto which the web is wound. Also, the positioning and rotation of the odd set of end chucks is controlled independently from the positioning and rotation of the even set of end chucks.




A still further embodiment of the present invention is an embodiment as immediately discussed where the sets of chucks are staggered so that when one pair of the odd set of end chucks finishes winding the web to produce a rolled product, one pair of the even set of end chucks begins winding the web to form another rolled product.




Another embodiment of the present invention exists in a rewinder as set forth above where the web is wound onto the core to form a rolled product by a combination of center winding from the end chucks and surface winding by the core and the web transfer device.




The present invention also provides for a rewinder that is used for winding a web to produce a rolled product. The rewinder includes a web transfer device for conveying the web. A core is located proximate to the web transfer device and the web is wound onto the core to form the rolled product. An applicator is located proximate to the web transfer device for applying adhesive to the web.




The present invention also includes an embodiment of a rewinder as previously discussed where the applicator applies adhesive to the leading edge of the web to assist in transfer of the web from the web transfer device onto the core. The applicator also applies adhesive to the trailing edge of the web to fix the trailing edge of the web onto the web that is wound onto the core.

DETAILED DESCRIPTION




Reference will now be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention and is not meant as a limitation of the invention. For example, features illustrated or described as part of one embodiment can be used with another embodiment to yield still a third embodiment. It is intended that the present invention include these and other modifications and variations.




Referring now to the drawings,

FIG. 1A

shows a rewinder


10


for use in winding a web


12


to produce a rolled product


20


(as seen in FIG.


1


C and FIG.


1


D). The rolled product


20


that may be produced can be of any number of types of products such as hand towels, toilet tissue, paper towels, or the like. The web


12


is shown in

FIG. 1A

as being transported by a web transfer device


30


in the direction indicated by arrow W. The web


12


that is shown being transported may be downstream from a parent roll (not shown) or downstream from a tissue machine or the like (not shown). The web transfer device


30


that transports the web


12


may be a vacuum bedroll or a vacuum conveyor. Such a device is advantageous in that it can hold the web


12


onto the surface of the web transfer device


30


without damaging the web


12


.




The web


12


is transported by the web transfer device


30


into contact with a tension roll


24


. An applicator


22


is present downstream from the tension roll


24


. In one embodiment, the tension roll


24


may be used to increase the tension on the web


12


and therefore allow for a more advantageous application of adhesive by the applicator


22


. Adhesive may be applied to the web


12


at the leading edge of the web


12


so that the web


12


will become securely engaged with a core


14


as the web


12


is wound around the core


14


. Also, adhesive may be applied by the applicator


22


to the tailing edge of the web


12


so that the web


12


will be adhered to itself once the web


12


is completely wound around the core


14


to produce the rolled product


20


.




The tension roll


24


may also be used in order to break the web


12


. However, it is to be understood that other means of breaking the web


12


may be employed such as for instance by a cutting paddle


60


. Additionally, it is not necessary that the tension roll


24


be used to break the web


12


.




A basin


46


is present and may be used to collect extraneous adhesive or other matter, or may be a vacuum plenum that holds the leading edge of the web


12


from cut-off to core


14


. An air blast device


18


is shown being proximate to the basin


46


and below the surface of the web transfer device


30


. The purpose of air blast device


18


is to produce an air blast to urge the leading edge of the web


12


up to and in contact with the core


14


.




Cores


14


are delivered to the rewinder


10


via a core unloading device


43


. A wheel


44


is present that rotates in the direction of arrow B in FIG.


1


A. Wheel


44


engages the cores


14


and the core unloading device


43


and places them in a controlled manner within a holder on the core transfer device


41


. The core transfer device


41


rotates in the direction of arrow C in FIG.


1


A. It can be seen from

FIG. 1A

that the core transfer device


41


moves cores


14


into close proximity with an even transfer belt


50


and an odd transfer belt


52


.




The even transfer belt


50


and odd transfer belt


52


have a plurality of end chucks, indicated generally at


16


, located thereon such that the end chucks


16


are transported by the odd and even transfer belts


52


and


50


. The direction of the end chucks


16


is indicated by arrow A in FIG.


1


A. The end chucks


16


are divided into a set of even end chucks


28


and a set of odd end chucks


26


. The even end chucks


28


and odd end chucks


26


are offset from one another as can be seen in FIG.


2


A.




The even transfer belt


50


is driven by a variable speed drive


40


, and the odd transfer belt


52


is driven by a variable speed drive


42


. The variable speed drives


40


and


42


therefore allow for the positioning of the end chucks


16


. The variable speed drives


40


and


42


may be controlled such that precise speed and direction of the end chucks


16


is achieved. The even set of end chucks


28


and odd set of end chucks


26


have their locations shown in FIG.


2


A. However, it is to be understood that the configuration of the end chucks


16


themselves may be modified as is commonly known in the art. Also, the arrangement of the even transfer belt


50


and the odd transfer belt


52


may also be modified from the embodiment shown in FIG.


2


A. For instance, the belts may be expanded to a location designated as reference numeral


54


. This has not been shown in

FIG. 2A

due to the fact that it would obstruct the viewing of the even set of end chucks


28


and odd set of end chucks


26


.




The even transfer belt


50


and odd transfer belt


52


shown in

FIG. 1A

has a cam section


34


. Cam section


34


is present in order to ensure the proper winding of a rolled product


20


(as seen in FIG.


1


C). This is because a rolled product


20


will have its diameter grow at a different rate as it is rolled. The embodiment shown in

FIG. 1A

could have the horizontal velocity of the core


14


remain constant as the rolled product


20


is being rolled, but have the speed in the vertical direction varied in order to compensate for changes in the diameter growth rate. Cam section


34


therefore allows for the varying of the speed in the vertical direction of core


14


as the rolled product


20


is wound. However, it is to be understood that a cam section


34


is not necessary and that the varying diameter build rate of the rolled product


20


may be controlled by other means. For instance, it could be possible to vary the speed of the core travel in the horizontal direction (relative to the surface of the web transfer device


30


) by proper timing of the variable speed drives


40


and


42


in order to adjust for the changes in the rolled product


20


build rate. In this instance, it may also be the case that the cam section


34


would not be present and that the core


14


would travel in a straight line at an angle to the horizontal plane (surface of the web transfer device


30


).




A rolled product transfer device


48


is present and is located adjacent to the web transfer device


30


in FIG.


1


A. Once formed, a rolled product


20


may be removed from the end chucks


16


and placed onto the rolled product transfer device


48


.

FIG. 2A

shows one method of removing the rolled product


20


from the end chuck


16


. The cam


120


is angled away from the rolled product transfer device


48


as the end chucks


16


come within close proximity to the roll transfer device


48


. Doing so would remove the end chucks


16


from engagement with the core


14


and allow for the rolled product


20


to be removed from the rewinder


10


.





FIG. 1B

shows an embodiment of a rewinder


10


having a perforator


56


located upstream from the even transfer belt


50


and odd transfer belt


52


. The perforator


56


is provided to place perforations into web


12


so that individual sheets may be separated once the rolled product


20


is formed. Located downstream from the perforator


56


is a vacuum transfer roll


58


. Vacuum transfer roll


58


is vacuum supplied so that the web


12


may be transferred around a partial circumference of the vacuum transfer roll


58


. The cutting paddle


60


is provided adjacent to the vacuum transfer roll


58


and is used to sever the web


12


so that individual rolled products


20


may be formed.

FIG. 1B

also shows the web


12


at a point where engagement with a core


14


occurs. The air blast device


18


is activated in order to help urge the web


12


against the core


14


. As previously indicated, adhesive may be applied to the leading edge of web


12


in order to help secure the web


12


onto the core


14


during winding.

FIG. 1B

also shows a chuck rotation mechanism


66


that is used to affect rotation of the end chucks


16


. This rotation is only needed in the section of the even transfer belt


50


and odd transfer belt


52


in which winding takes place. In the embodiment shown in

FIG. 1B

there is no reason for the end chucks


16


to be rotated other than during the point where winding takes place, although it is to be understood that the present invention is not limited to having the end chucks


16


rotate only during the winding of the rolled product


20


.




The chuck rotation mechanism


66


is comprised of chuck rotation rolls


62


and


64


. In communication with the chuck rotation rolls


62


and


64


is a variable speed drive


36


. The variable speed drive


36


may also have a roll associated therewith so that an even rotation belt


70


is looped around these three rolls, and driven by the variable speed drive


36


. Offset from the even rotation belt


70


is an odd rotation belt


68


that is looped around the chuck rotation roll


64


and


62


in addition to a variable speed drive


38


which may have a roll associated therewith.

FIG. 2B

shows this arrangement wherein the motor that runs the variable speed drive


38


is not shown for purposes of clarity. It may also be the case that the odd rotation belt


68


and even rotation belt


70


are driven by the same variable speed drive, however the embodiment in

FIG. 2B

has them being driven by separate drives


36


and


38


.




The end chucks


16


are moved along the even transfer belt


50


and odd transfer belt


52


in a manner disclosed previously for the embodiment shown in FIG.


1


A. Upon reaching the point where the web


12


is transferred to the core


14


, the core


14


and one set of end chucks


16


(that being an even set of end chucks


28


in

FIG. 1B

) are then placed in contact with the even rotation belt


70


. The even pair of end chucks


28


has a drive belt pulley


80


in communication therewith so that the even pair of end chucks


28


are rotated once the drive belt pulley


80


contacts the even rotation belt


70


. A drive belt pulley


80


on an end chuck


16


may be configured for instance as shown in FIG.


3


A. Therefore, the even set of end chucks


28


are rotated during the time in which the rolled product


20


is wound. Once the rolled product


20


is wound, the engagement with the even rotation belt


70


is no longer present, and the even set of end chucks


28


are no longer rotationally driven. The rotation of the odd set of end chucks


26


is affected in a similar manner. However, the positioning of the drive belt pulley


80


is located at a different location of the odd set of end chucks


26


as the even set of end chucks


28


. This is due to the offsetting of the odd rotation belt


68


and even rotation belt


70


. As can been seen, the odd rotation belt


68


and even rotation


70


may be driven at different rotational speeds. Also, they may be independently controlled where if one rotation belt becomes disabled, the rewinder


10


can continue operations with the working rotation belt to produce rolled product


20


without interruption of the rewinder


10


.




In addition to having an air blast from air blast device


18


assist in the transfer of the web


12


onto the core


14


, a transfer assist device


72


as shown in

FIG. 1C

may also be employed. The transfer assist device


72


may be for instance an eccentric cam that can be used to deflect the belt of the web transfer device


30


and the web


12


transferred thereon up onto the core


14


. However, it is to be understood that a web


12


may be transferred onto the core


14


simply by having the core


14


being pressed down onto web transfer device


30


in order to press against the web


12


which has adhesive applied thereto.




As indicated, the roll product


20


may be formed by having the end chucks


16


engage the core


14


and rotate the core


14


having a leading edge of web


12


attached thereto. This winding is known in the art as center winding, and will form a rolled product


20


by wrapping the web


12


about itself Surface winding may also be employed in conjunction with or alternatively to the embodiments of the present invention. Surface winding of the web


12


can be affected by a combination of the core


14


with the web transfer device


30


. Contact of these two will cause a nip to be formed between the web transfer device


30


and the core


14


therefore causing surface winding of the web


12


about the core


14


. As can be seen, the rolled product


20


can be formed by either center winding, surface winding, or a combination of center and surface winding. As previously discussed, this versatility allows for the rewinder


10


to produce rolled products


20


having varying characteristics. Production of rolled products


20


in this manner may therefore allow for the rewinder


10


to eliminate the winding of parent rolls and the subsequent unwinding of parent rolls.




A winding belt


32


may also be employed in the rewinder


10


. Such a winding belt


32


is disclosed in FIG.


1


C. The winding belt


32


can be used to assist with the driving of the core


14


to wind the web


12


. The winding belt


32


is positioned proximate to the area of winding of the rolled product


20


. Winding belt


32


is composed of winding belt rolls


76


and


78


and is driven by a winding belt drive


74


. A winding belt


32


is positioned at an angle relative to the web transfer device


30


in order to compensate for rolled product


20


growth during the winding. In some embodiments of the present invention, it may be the case that the winding belt


32


may wind the web


12


onto the core


14


without use of a center winding effect by the end chucks


16


. Here, the end chucks


16


would simply control the positioning of the core


14


. Also, a winding belt


32


may be used to stabilize the rolled product


20


as it is being wound.




The rewinder


10


therefore allows for a combination center/surface winding of web


12


to form the rolled products


20


which are the finished product consumer rolls. However, a winding belt


32


is not necessary in order to achieve this result.




As stated, the applicator


22


is provided in order to apply adhesive to the leading edge of the web


12


. The same applicator


22


or a second applicator (not shown) could be used to apply adhesive to the trailing edge of the web


12


in order to seal the tail of the rolled product


20


. The benefits of having the applicator


22


apply adhesive directly to the web


12


could be for instance the elimination of having adhesive fly from the core


14


prior to the transfer of the web


12


onto the core


14


. Also advantageous in such an embodiment is the elimination of a secondary process step for applying adhesive to the tail of the web


12


.





FIG. 1D

shows several rolled products


20


being produced by the rewinder


10


. It can be seen that the end chucks are positioned such that once the winding of one of the rolled products


20


is complete, another of the end chucks


16


and core


14


are positioned to engage the leading edge of a web


12


. In other words, as soon as one of the rolled products


20


is completed, winding of another rolled product


20


begins. However, it is to be understood that such an arrangement is not a limiting feature of the invention.




Due to the fact that the rolled product


20


will have a smaller diameter during the beginning of winding, it may be necessary for some embodiments of the present invention to have the end chucks


16


rotated at a faster rate once winding starts. Once the rolled product


20


reaches a larger diameter, it builds slower so the rotation of the end chucks


16


may be slowed down in order to compensate.




The end chuck


16


described in the present invention may be configured, for instance, as shown in FIG.


3


A. The end chucks


16


are comprised primarily of a cylindrical rod


100


that is housed within bearings


82


and


84


. Bearings


82


and


84


may be connected to the even or odd transfer belts


50


and


52


so that the end chuck


16


can rotate relative to the even or odd transfer belt


50


and


52


. As previously discussed, the rotation of the end chuck


16


is affected by the contact of either the odd or even rotation belts


68


and


70


with the drive belt pulley


80


. Engagement of the drive belt pulley


80


with one of these belts causes the end chuck


16


to rotate due to a secured connection between the drive belt pulley


80


and the cylindrical section


100


of the end chuck


16


.




In order to engage the core


14


, the end chucks


16


must be inserted into the hollow cavity


102


of the core


14


. An end chuck


16


is inserted into each end of the hollow cavity


102


of the core


14


. Such an insertion on one end of the hollow cavity


102


is shown in FIG.


3


B. In order to move the end chuck


16


into the hollow cavity


102


of the core


14


, a drive gear or pulley


86


is employed. The drive gear or pulley


86


is configured to contact another belt system (not shown) similar to that of the chuck rotation mechanism


66


. Here however, rotation of the drive gear or pulley


86


causes the end chuck


16


to move linearly with respect to the core


14


. This is due to the fact that the drive gear or pulley


86


has an internal spline which is geared with the cylindrical section of the end chuck


16


. Therefore, the rotational movement of the drive gear or pulley


86


is translated into linear movement of the end chuck


16


.




The end chuck


16


has a tip


88


. Tip


88


is tapered in order to allow for some error in the insertion of the end chuck


16


into the core


14


. As shown in

FIGS. 3A and 3B

, a bladder arrangement


110


is located adjacent to the tip


88


. In one embodiment of the present invention, the bladder arrangement


110


is provided with a pneumatic line


112


. Once inserted into the core


14


, the pneumatic line


112


provides pressure into the bladder arrangement


110


so that the bladder arrangement


110


expands and engages the inner circumference of the core


14


to securely hold the core


14


and translate the rotation of the end chucks


16


to the core


14


.




Once the rolled product


20


is completely wound, the pressure imposed on the bladder arrangement


110


is removed. This causes the rotation of the end chuck


16


to no longer transmit to the core


14


. The drive gear or pulley


86


may be engaged by another belt system (not shown) in order to affect a linear withdrawal of the tip


88


of the chuck


16


from the hollow cavity of the core


14


. Also, as shown in

FIG. 2D

, core chuck position cam


120


may in one embodiment be simply angled away from the web transfer device


30


such that the end chucks


16


are pulled out of the core


14


. It is to be understood in the present invention that various ways of engaging and disengaging the end chucks


16


from the core


14


are possible. Also, the two techniques disclosed may be combined with themselves or with other ways to effect these engagements and disengagements.




It should be understood that the invention includes various modifications that can be made to the embodiments of the mandrelless center/surface rewinder described herein as come within the scope of the appended claims and their equivalents.
