Description




BACKGROUND OF THE INVENTION




The present invention relates generally to handling large rolls of paper. More particularly, this invention pertains to the application of a protective covering to an unprotected paper roll in locations without major paper handling equipment.




In the printing and paper industry, large rolls of paper are handled and processed. In the course of this processing, rolls are sometimes damaged and must be scrapped or may be salvaged by the process and machine of U.S. Pat. No. 5,964,024, issued to Wallace on Oct. 12, 1999, entitled “Roll-Cutter” which is currently in use in the industry. This patent is hereby incorporated by reference. Often, the paper is simply of the incorrect dimension and may be resized by the roll cutter to a usable size.




When the roll cutter is used to resize a roll, at least one of the headers is removed during the cutting operation. This leaves that end exposed to dirt and possible damage. When the roll is used at the same facility, this exposure is not significant because the duration of storage is usually minimal. However, where long term storage is needed, or when the resized paper roll must be transported to other facilities, the possibility for contamination and damage to the roll is increased. This mandates that a new wrapper, headers, and caps be applied to refurbish the roll.




Paper mills and large paper processing plants are equipped with machinery to apply wrappers and headers to the finished rolls. This machinery is large, complex, very expensive, and is certainly not portable. Large production machinery does not lend itself to small orders such as for samples or incidental damage. During an equipment breakdown at these large facilities, production will cease. In critical situations, this shutdown may have a significant economic impact. In addition, during application of the roll cutter where relatively few rolls of paper are involved, difficulty arises in re-wrapping and applying new headers. Transporting the rolls to a wrapping facility is cost prohibitive and would defeat the purpose of the roll cutter. The present invention provides a method to overcome the limitations on the prior art large production rate equipment.




The prior art roll covering application sequence is shown in

FIG. 1

, beginning at the left and progressing to the right, where a paper roll


10


is protected by wrapping the paper roll


10


in a with a heavy gauge of paper wrapper


12


, also call a body wrap


12


, which extends over the ends


18


of the paper roll


10


. The edges


14


of the body wrap


12


are then folded over the ends


18


of the paper roll


10


. The edges


14


are then unfolded and a disc


16


is inserted between the folded edges


14


and the end


18


of the paper roll


10


. The header disc


16


is a circular disc of heavy fibrous (cardboard) material approximating but smaller than the diameter of the roll


10


being refurbished and having a center hole corresponding to the diameter of the core tube. The protective disks


16


or headers


16


are applied to protect the ends


18


of the roll


10


from physical damage. The edges


14


of the wrapper


12


are then crimped back over the header


16


and a seal cap


20


is then applied and retained with adhesive to retain the body wrap


12


and eliminate contamination from dust and dirt. The end seal cap


20


is a circular disc of paper that is bonded to the crimped wrapper


12


to retain the crimp and exclude dirt from the paper roll. The cap


20


does not have a center hole to keep its sealing effect.




Current practices for wrapping small quantities of rolls is to lay the wrapper on the floor and manually roll the paper over the wrapper until it is wound around the roll. An alternative practice is to place the paper roll onto rollers to facilitate turning of the roll during re-wrapping. These rollers press into the wrapper and make it difficult to obtain a tight wrap.




The reconditioning of some rolls requires that the outer layers of paper be removed. Perhaps several inches of paper may need to be removed. The current practice is to slit the roll along its axis with a portable circular saw to the depth that needs to be removed. This creates a problem because rolls may be upwards of seven feet in diameter which will result in a slab of paper over twenty-one feet in length.




Additionally, the body wrap material is supplied on large rolls similar to the paper itself, only in wider dimensions. This presents the added difficulty of cutting the wrapper material to the size needed to handle an individual roll.




What is needed, then, is an apparatus and method to provide an inexpensive and portable system for paper roll refurbishing.




SUMMARY OF THE INVENTION




The present invention is directed to apparatus and methods to provide an inexpensive and portable system for paper roll refurbishing. Apparatus used in the present invention includes: an apparatus for holding the body wrapper supply roll and measuring the unrolled wrapper to a desired length; an apparatus for rewinding and cutting individual wrappers for transport to the point of use; an apparatus for applying the wrappers to the paper roll; an apparatus for crimping the body wrap over the end of the roll to retain the header; an apparatus for transporting the rolls from the resizing area to the wrapping area; and an apparatus for retention of the headers and caps under pressure during curing of the retaining adhesive.




These apparatus provide a system of machines and equipment that provide a comprehensive, low cost, portable system for refurbishing paper rolls.




This present invention provides a support for the body wrap and provides a way to unwind a predetermined length of body wrap material. This material is then rewound in small, easy to handle individual rolls. These pre-cut rolls may be cut to a shorter size and thus eliminate the need to obtain and store wrapper stock of various widths. In this manner, a single roll of wrapper can supply all of the sizes as required.




The present invention overcomes the problems with obtaining a tight wrap by supporting the roll from its center core and providing a powered rotation to overcome the limitations of the prior art.




The present invention provides for support of the roll from its center to elevate the roll to facilitate in removal of the excess or damaged paper, and the application, wrapping, and crimping of the body wrap material.




The present invention provides for an easily transportable roll for portable movement for refurbishing.




The present invention also provides for the retention of the body wrap during a bonding process to obtain a tightly wrapped roll.




A method for using the equipment and apparatus is also provided.




In this manner, the objective of providing improved process flow for each of the actions for refurbishing a paper roll are provided by the present invention.




Other objects and further scope of the applicability of the present invention will become apparent from the detailed description to follow, taken in conjunction with the accompanying drawing wherein like parts are designated by like reference numerals.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




As shown in

FIGS. 2 through 10

, the present invention provides a system of machines or equipment to provide a portable refurbishing system for a paper roll. The equipment includes a wrapper supply roll holding, measuring, re-rolling, and cutting station


200


; a paper roll wrap station


800


; a roll transporter


900


, and header and cap damping station


1000


.





FIGS. 2 through 5

show the wrapper supply roll holding, measuring, re-rolling, and cutting station


200


, also known as the wrapper supply roll station


200


. The wrapper supply roll station includes a main frame


202


, a loading carriage


204


, wrapper roll lifts


214


including a fixed roll lift assembly


206


and a moveable roll lift assembly


208


, and a measuring, re-roll and cut station


210


.




The main frame


202


is a stationary frame of suitable size for holding the rolls of body wrap material shown as the supply roll


203


. Typical supply rolls


203


of body wrapper material are up to seven feet in diameter and 152 inches long. The main frame


202


forms the base of the wrapper supply roll station


200


. Within the main frame


202


, four longitudinal beams


212


act as structural members to attach and support the wrapper roll lifts


214


. Two of these beams


202


act as tracks


216


for a movable loading carriage


204


.




The loading carriage


204


receives the roll of supply material


203


. The supply roll


203


is placed upon the carriage


204


that has two uprights


218


, one on each side, that retain the roll


203


on the carriage frame


220


. Rollers


222


mounted to the carriage frame


220


allow the carriage


204


to be moved back and forth along the tracks to the desired position. The loading carriage


204


may be moved along the tracks


216


and positioned for different lengths of supply rolls


203


. Once the supply roll


203


is placed on the loading carriage


204


, the spindles


226


are vertically adjusted to be placed at the height of the roll core


228


and the roll


203


and carriage


204


are moved to position the wrapper roll


203


such that the roll


203


may be lifted by the roll lifts


214


.




Each end of the main frame


202


is equipped with roll lifts


214


for lifting the supply roll


203


off of the carriage


204


. The fixed roll lift


206


is fixed in position on the frame


202


while the adjustable roll lift


208


is mounted on wheels


224


that allow the wrapper supply roll station


200


to accommodate various length supply rolls


203


. The adjustable lift


208


rides upon the same tracks


216


as the carriage


204


.




Each roll lift


214


is equipped with a spindle


226


that inserts into the core


228


of the supply roll


203


. The spindle


226


of each lift


214


is attached to a vertically mounted guide plate


234


moving between guide tracks


238


. The vertically mounted guide plate


234


is connected to a hydraulic cylinder


236


to provide the controlled vertical movement of the plate


234


within the tracks


238


. The cylinders


236


are actuated to raise and lower the supply roll


203


. Each lift


214


is equipped with an independent hydraulic power unit that powers the cylinders


236


and in the instance of the fixed lift


206


, powers a hydraulic wrapper supply roll rotation motor


230


. The spindle


226


of the fixed lift is powered by a hydraulic motor


230


attached to the spindle through a drive


232


so that it can rotate the supply roll


203


for unwinding the wrapper. The spindle


226


of the movable lift


208


acts as an idler and is used to support and lift the supply roll


203


.





FIG. 2

is an end view of the wrapper supply roll station


200


showing a supply roll


203


loaded onto the carriage


204


.

FIG. 2A

is a more detailed end view showing a web path through the guide


246


, clamp


248


, measuring wheel


250


, and rollup shaft


254


. The path of the supply material web


244


is shown going under a horizontal guide member


246


, over a horizontal web clamp bar


247


, under a pivoted web clamp


248


, under a measuring wheel


250


, over a cutting guide member


252


, and finally onto roll-up shaft


254


.





FIG. 5

shows a second hydraulic wrapper rotation motor


256


that pulls the wrapper web


244


from the supply roll


203


and turns the roll-up shaft


254


. The roll rotation and wrapper motors


230


,


256


are coordinated such that the supply roll


203


is rotated in harmony with the roll-up shaft


254


so as to maintain tension on the web


244


for a wrinkle free product during the transfer.




As shown in

FIGS. 2

,


2


A, and


5


, the measure wheel


250


is a commercially available instrument. The measure wheel


250


allows a preset length to be programmed into its controls to stops rotation of the supply roll


203


and roll up shaft


254


when the correct length of wrapper web


244


has been moved onto the roll up shaft


254


.




A pivoted clamp


248


that is self actuated by gravity holds the supply wrapper web


244


in place against the horizontal web clamp bar


247


. The guide-cutting member


252


includes an upper support area


256


with a slot


258


so that a knife may be used to sever the wrapper web


244


along the guide cutting member


252


. The knife blade is pulled along the slot


258


such that the wrapper web


244


is supported on both sides of the slot


258


. Pivoted clamp


248


prevents web


244


from being pulled from the guides when the web


244


is cut.




The roll-up shaft


254


has opposed longitudinal bars


260


that are cammed into an extended position by a cam activation device


253


when the shaft


254


is rotated. This effectively increases the diameter of the shaft


254


. After the correct amount of wrapper


244


has been measured and cut from the supply roll


203


, these bars


260


are retracted an end support


262


is disconnected to allow for an axial removal of the pre-cut wrapper


12


. This results in a roll of approximately six to eight inches in diameter that maybe easily transported. Adhesive backed tape, not shown, is applied to the trailing edge of the pre-cut wrapper


12


to prevent unrolling. These pre-cut wrappers


12


may then be further packaged if they are to be shipped to a remote location. The pre-cut wrapper


12


may be cut to a new desired axial width by well known methods, such as the use of a circular saw.





FIGS. 6 and 7

show the wrapping carts


600


used in the paper roll wrap station


800


shown in FIG.


8


. Two of these carts


600


are required to lift and rotate the paper roll


10


that is to be refurbished. Each cart


600


is identical consisting of a framework


602


mounted on rollers


604


for mobility. A vertical portion


606


of the frame


602


forms tracks


608


as a guide for a plate


609


supporting a powered spindle


610


that is attached to a vertically mounted hydraulic cylinder


612


. Hydraulic motors


614


power the spindles


610


through drives


616


, shown as a chain drives, which rotate the roll


10


during the wrapping procedure. Hydraulic motors


614


are powered by a hydraulic power unit consisting of an electric motor of approximately 1½ hp., a commercially available hydraulic pump, valves, and other standard components found in a hydraulic power system. Hydraulic motors


614


are connected to a gear reducer and a one way clutch which drives spindle


610


. The clutch allows the motor to drive spindle


610


but prevents the pump from being turned backward by the spindle. The gear reducer output speed is about 54 rpm.




The carts


600


are positioned at each end of the paper roll. A header is placed onto the spindle


610


for use at a later time. The spindle


610


is then inserted into the ends of the rolls


10


and the roll


10


is then lifted using the spindle


610


and the grippers


618


. As shown in

FIG. 6A

, a segmented gripper


618


of the correct size for the core tube of the paper roll


10


is placed on each spindle


610


. The segmented gripper


618


is shown in FIG.


6


A and includes a set of eight segments


620


held on by a ring


622


such that the segments


620


may expand the diameter of the spindle


610


to fit the inside diameter of the roll


10


core. Segments


620


fit on the small diameter adjustment shaft


624


of the spindle


610


. Retracting this adjustment shaft


624


into the spindle


610


causes the segments


620


of the gripper


618


to expand to grip the interior


13


of the core tube


11


to prevent slippage. The most prevalent core sizes are 3″ and 6″ but other sizes may be accommodated.




To lift the roll


10


, the spindles are positioned so as to enter the hollow core tube


11


in the center of each roll


10


. The spindles


610


are then elevated which lifts the paper roll


10


off of the floor. The front edge of a precut body wrapper


12


is attached to the paper roll


10


using tape (not shown). The spindle motors


614


then rotate the roll


10


causing the wrapper


12


to wind about the roll


10


. The trailing edge of the wrapper


12


is then secured using an adhesive tape


265


as shown in FIG.


9


. Note: a one-way clutch is utilized in the gearbox of each cart. This prevents the hydraulic motor


614


from being driven backwards and becoming a pump when it is driven in the opposite direction by the opposing drive motor as previously described.




As noted in the process of

FIG. 1

, the next step is to crimp the edges


14


of the resulting body wrapper


12


that overhangs the paper roll


10


by about six inches on each end


18


. As shown in

FIGS. 6 and 8

, each cart


600


is equipped with a circular rotating element crimper


622


, also known as a crimp disc


622


, consisting of five blades


624


, which is used to perform a crimp to the overhung body wrap material


14


. A hydraulic disc motor


626


mounted to a frame


628


powers the crimper


622


. This frame


628


is pivoted at pivots


630


,


632


operating in two directions at the bottom of the frame


628


. The rotational speed of the crimper is approximately 54 rpm.




As shown in

FIG. 8

, one pivot


630


allows the crimper


622


to rotate in toward the end


18


of the roll


10


. This positions the plane of the crimping disc


622


in the same plane as the end


18


of the roll


10


. The other pivot


632


allows the disc


622


to move parallel with the end


18


of the roll


10


. In use, the crimper disc


622


is first rotated away from the outer diameter surface of the paper roll


10


. When placed into motion, the roll


10


and the crimper


622


are both rotating. The crimper


622


is slowly pivoted into the roll


10


until the crimper


622


begins to bend the wrapper overhang


14


ninety (90) degrees to be parallel with the end


18


of the roll


10


. A fold


15


or crimp is formed as the crimper


622


is pivoted toward the axis of the roll


10


. The resulting folded over crimp retains the protective header


16


that will be inserted. A wireless foot switch


634


is used to control the rotation of the crimper


622


. This eliminates the electrical cable and the associated hazards and inconveniences that would otherwise exist.




In order to allow use of the mobile roll wrapper from readily available electrical power, namely 120 volts 60 Hz operation in the United States, the size of the electric motors (1½ hp) for the hydraulic pumps are limited in size to prevent overloading of the circuits. Each cart may be connected to a separate electrical power supply circuit in order to prevent overloading of the circuits. This motor size limitation allows operation of either the roll motor


614


or the crimper motor


626


, but would not allow the operation of both motors simultaneously off of the same low power circuit. To explain: When cart #


1


rotates the roll, the opposite cart #


2


powers the Crimper


622


on cart #


2


. The roles of the carts are then changed so that cart #


2


turns the roll and cart #


1


powers the Crimper


622


on cart #


1


. Thus only one motor per cart is connected to the electrical power source. This allows the use of both motors off of standard circuits for portable operation that does not require a fixed high power supply.





FIG. 9

shows the roll transporter


900


. When the crimping operation is complete the roll


10


is lowered onto a modified version of a commercially available pallet jack


902


for transport to the header and cap clamping station


1000


. This jack


902


is modified to retain the roll


10


with two uprights


904


, one on each side of the jack


902


, that retain the roll


10


on the pallet jack


902


. Rollers


906


mounted to the jack


902


allow the jack


902


to be moved to the desired position for installing the header


16


and cap


20


end protection.





FIG. 10

shows the header and cap clamping station


1000


. The clamping station


1000


equipment consists of vertical end frames


1002


of structural steel that support an overhead steel beam


1004


. Two commercially available lifting hoist trolleys


1006


ride on the lower flange


1007


of this beam


1004


. This assembly is approximately 14-ft long×5-ft wide×8-ft high. Attached to each trolley


1006


is a spreader bar


1008


of structural steel about 4-ft long. A holding chain


1010


is affixed to each end


1012


of this spreader bar


1008


. These holding chains


1010


support a steel clamp plate


1014


that may assume various dimensions depending upon the size of the paper roll


10


being refurbished. A typical dimension may be 4-ft×5-ft. These plates


1014


are reinforced with structural steel shapes


1016


to reduce bending. A clevis


1018


is affixed at the mid-point


1020


and near the side edge


1022


of each of these two plates


1014


.




Additional components include two hydraulic cylinders


1024


attached to a length of clamping chain


1026


on each side of the clamping station


1000


. These cylinders


1024


have a stroke length of say 10-inches and are capable of exerting a force of up to 10,000 lbs. This force level is not required and is limited by controlling the hydraulic pressure.




The trolleys


1006


and attached clamp plates


1014


are moved toward the ends


1028


of the trolley beam


1004


. A paper roll


10


previously rewrapped and crimped is moved under the clamping equipment


1000


. Adhesive is applied to an end cap


20


and to the crimped body wrap


14


. The end cap


20


is placed against the crimped wrap


14


.




The trolleys


1006


are rolled toward the paper roll


10


until each clamp plate


1014


is against the end cap


20


. One end


1030


of the pull-back cylinder


1024


is connected to a clevis


1018


on one clamp plate


1014


. The other end


1032


of the cylinder


1024


connects to the chain


1026


that is affixed to a clevis


1018


on the opposite plate


1014


. This connection is made with the cylinder


1024


extended.




Hydraulic pressure is applied to the cylinders


1024


on each side of the plates


1014


that retract, drawing the clamp plates


1014


against the paper roll


10


. The control system uses a preset hydraulic pressure to stop the cylinders


1024


, thus maintaining force against the roll end caps


20


. This force is maintained for a recommended time period adequate to allow the adhesive to cure.




The clamp plates


1014


are released and the roll is removed from the clamping station


1000


. Product identification labels (not shown) are applied thus completing the refurbishing process. The refurbished roll is then transported to an appropriate location.




A commercially available self-contained hydraulic power unit (#4ZC75 for ref only) is utilized to operate the clamp cylinders


1024


. This is a ½ horsepower 120-volt unit capable of pressures adjustable to 10,000 psi. It is typically set at 3000 psi. for operating the clamp cylinders. The power unit is controlled by a pendant type control shown in

FIG. 10

that allows the cylinders to be retracted and held in the clamped position and then extended to release the clamp plates.




Thus, although there have been described particular embodiments of the present invention of a new and useful Apparatus and Method for Paper roll Refurbishing, it is not intended that such references be construed as limitations upon the scope of this invention except as set forth in the following claims.
