Description




BACKGROUND OF THE INVENTION




The present invention is drawn to a device for laminating labels. More specifically the present invention is a laminating device for precisely and accurately placing a protective film over an existing label that is on a liner material.




Many manufacturers of diverse products desire to include product and manufacturer information upon their products. One method of including such information with a product is to include a pamphlet or other literature with the product. However, literature is very often misplaced, damaged or destroyed, thereby resulting in the loss of all the information that the manufacturer wished to include with the product.




Another more permanent method of including information with a product is to engrave it upon a metal plate which would then be affixed to the product with mechanical fasteners or with an adhesive. The drawback to using metal plates to carry information is that the cost of the plates themselves, and engraving them, are relatively high.




An alternative to the use of included literature and engraved plates is the adhesive label. Adhesive labels can come in many sizes and shapes, in a variety of colors and patterns, and readily receive printing as from a laser printer, resin printing process, or a thermostatic printer. Adhesive labels also have the advantage of being very inexpensive.




Labels can also be designed for use in a wide range of environments. For example, adhesive labels are now being used in place of engraved metal plates as engine labels. An adhesive label designed for use as an engine label must withstand extreme heat without peeling or burning. An adhesive engine label must also be able to withstand water, oil, gasoline, and other chemicals or liquids without peeling. Finally, as the information on engine labels is sometimes critical, the labels must be tamper resistant, i.e. the labels must be difficult to remove and must indicate, by tearing or other damage, that they have been tampered with.




Adhesive labels that are to be used in a high speed manufacturing setting such as on an engine assembly line must also be capable of being mass produced. This need has been met by adhering continuous sheets of a suitable label material to a continuous sheets of releasable liner material and passing the resulting combination through a standard stacked die cutting system to form the unlaminated labels. The stacked die cutting system cuts tractor feed holes through each edge of the liner, cuts the outlines of the labels into the face of the label material, and forms perforations, security cuts, and printer registration holes through the liner material and label material. The stacked die cutting systems used to make the unlaminated labels also peel away the excess label material, leaving only labels of the desired size and shape disposed on the liner material.




Because adhesive labels are being increasingly used in applications where the materials commonly used in fabricating adhesive labels will not withstand the environmental conditions, it is important to tailor the structure and materials of the adhesive label according to the demands of the situation. In addition to, for example, fabricating labels from substrates and adhesives that are resistant to heat and oils, a clear laminate that is also resistant to heat and oils may be laid over an adhesive label. Such a laminate will prevent chemicals and even ultraviolet light from degrading the substrate of the label, the adhesive, or the printing on the label.




The present invention is a device for applying a laminate to an adhesive label. The laminating device of the present invention is capable of quickly, precisely, and accurately applying laminates over a large number of shapes and sizes of labels. The laminating device of the present invention is also capable of die cutting the laminate layer to be applied over the label so that the edges of the laminate and the label evenly offset around the entire perimeter of the label.




SUMMARY OF THE INVENTION




The present invention is a device for laminating labels which are typically disposed on a continuous strip of a liner material in a predetermined arrangement. The strip of liner material has parallel edges that are provided with a plurality of tractor feed holes arranged in registration with the predetermined arrangement of the labels disposed upon the liner material. The device for laminating the labels comprises a motor mechanism mounted between a first frame plate structure and a second frame plate structure so that the first and second frame plate structures are spatially oriented in a substantially parallel planar relation to one another. A label supply spindle structure and a, label take-up spindle structure are mounted upon the first frame plate structure with the label supply spindle structure being arranged to receive a roll of unlaminated labels and the label take-up spindle structure being arranged to receive a roll for winding up the labels once they have been laminated. The label supply and take-up spindle structures each have coupled thereto a clutch mechanism for driving the respective spindle structures. The clutch mechanisms coupled to the label supply and take-up spindle structures derives its motive power from the motor mechanism.




A laminate supply spindle structure, a laminate liner take-up spindle structure and a laminate waste take-up spindle structure are also mounted upon the first frame plate structure. The protective film and the laminate liner material also have tractor feed holes formed therein. The laminate supply spindle structure is arranged to receive a roll of a protective film disposed upon a continuous strip of a laminate liner material, the laminate liner take-up spindle structure is arranged to receive a roll for winding up the strip of laminate liner material after the protective film has been removed therefrom, and the laminate waste take-up spindle structure is arranged to receive a roll for winding up the protective film not used in laminating the labels. In addition, the laminate supply spindle structure, laminate liner take-up spindle structure, and laminate waste take-up spindle structure each have coupled thereto a respective clutch mechanism. The clutch mechanisms coupled to the laminate supply, laminate liner, and laminate waste take-up spindle structures derive motive power from the motor mechanism.




A laminating structure is also mounted between the first frame plate structure and the second frame plate structure, the laminating structure operating to apply the protective film to the labels in registration with the predetermined arrangement of the labels upon the liner material. The laminating structure is also powered by the motor mechanism via a plurality of clutch mechanisms.




The spindle structures and laminating structure are controlled by a control mechanism that controls the lamination of the labels.




The laminating structure itself comprises an inner laminate stripping drum and an outer laminate stripping drum. The inner and outer laminate stripping drums are slidingly disposed within a first pair of parallel slots formed between the first and second frame plate structures such that the inner and outer laminate stripping drums are in contact with one another. The inner and outer laminate stripping drums each have respective clutch mechanisms coupled thereto for driving the inner and outer laminate stripping drums. As with the spindle structures, the respective clutch mechanism of the inner and outer laminate stripping drums derive motive power from the motor mechanism.




The inner and outer laminate stripping drums cooperate to draw the strip of protective film from the roll received upon the laminate supply spindle structure. The protective film is separated from the liner material by the action of the inner and outer laminate stripping drums. The protective films conveyed by the inner laminate stripping drum into the laminating structure and the laminate liner material is conveyed by the outer laminate stripping drum to the roll received upon the laminate liner take-up spindle structure.




The protective film is received from the inner laminate stripping drum by a toothed drive wheel having a clutch mechanism coupled thereto. The clutch mechanism coupled to the toothed drive wheel derives its motive power from the motor mechanism. The toothed drive wheel is in close proximity to the inner laminate stripping drum such that the protective film may be transferred from the inner laminate stripping drum to the toothed drive wheel thereby becoming adhered to the liner material upon which the labels are disposed. The teeth of the drive wheel are arranged to engage the tractor feed holes formed in the protective film and the liner material upon which the labels are disposed.




A die-cutting drum is slidingly disposed within a second pair of parallel slots formed between the first and second frame plate structures. The die cutting drum is constrained to rotate in registration with the toothed drive wheel. The die-cutting drum has a plurality of blades disposed upon the surface thereof, the blades being arranged to cut only the protective film that is adhered to the liner material having the labels disposed thereon. The cuts in the protective film are in registration with the labels disposed upon the liner material and are offset a predetermined distance from the edge of the labels disposed upon the liner material. The protective film not covering the labels is separated from the liner material upon which the now laminated labels are disposed and is wound up upon the roll received upon the laminate waste take-up spindle structure. The die-cutting drum of the present invention is interchangeable with a plurality of die-cutting drums having blades arranged in a plurality of predetermined manners.




An inner label feed drum is slidingly disposed within a third pair of parallel slots formed between the first and second frame plate structures. The inner label feed drum has coupled thereto a clutch mechanism which derives motive power from the motor mechanism. The inner label feed drum is located immediately adjacent the toothed drive wheel so as to convey the liner material upon which the now laminated labels are disposed to the roll received upon the laminated label take-up spindle structure.




A first tensioning device is coupled to the inner and outer laminate stripping drums disposed within the first parallel slot formed between the first and second frame plate structures. A second tensioning device is coupled to the die-cutting drum disposed within the second parallel slot formed between the first and second frame plate structures. A third tensioning device is coupled to the inner label feed drum disposed within the third parallel slot formed between the first and second frame plates. Each of the three tensioning devices is capable of altering the tension placed upon the laminate liner material and the liner material upon which the labels are disposed by altering the linear location of the inner and outer laminate stripping drums, the die-cutting drum, and the inner label feed drum, respectively, within their respective parallel slots.

DETAILED DESCRIPTION




Although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structure. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.




Referring first to

FIG. 1

, the laminated labels


10


produced by the laminating device


20


are comprised of a label


12


covered by a layer of protective film


36


, the label


12


and the protective film


36


both being disposed upon a liner


42


. The laminating device


20


which produces the laminated labels


10


is illustrated in FIG.


4


and comprises a chassis


22


upon which are mounted a motor


24


, a plurality of reel spindles


26


,


28


,


30


,


32


,


34


, a laminating structure


38


for applying the protective film


36


to the labels


12


, and a control means (not shown) for controlling the interaction of the reel spindles


26


,


28


,


30


,


32


,


34


with the laminating structure


38


.




Both the unlaminated labels


12


and the protective film


36


are initially provided upon their own it respective liners


42


. In the preferred embodiment of this invention the respective liners


42


used with both the labels


12


and the protective film


36


are identical in dimension. The liners


42


used with the present invention are in the form of a continuous strip of material that has at least one coated surface


44


upon which the labels


12


and the protective film


36


are disposed. The adhesive


46


of the labels


12


and the protective film


36


will adhere to the coated surface


44


of the liner


42


but will be easily and cleanly releasable therefrom, i.e. the adhesive bond between the adhesive


46


and the coated surface


44


of the liner


42


is significantly weaker than the adhesive bond between the adhesive


46


and the labels


12


or the protective film


36


. It is to be understood that the adhesive used with the labels


12


and the protective film


36


may be the same adhesive, or, if an application so requires it, a different adhesive.




The liner


42


, as drawn in

FIG. 1

, has parallel edges


48


and


50


. Offset a predetermined distance from each of the parallel edges


48


and


50


of the liner


42


are a plurality of tractor feed holes


52


. The tractor feed holes


52


are evenly spaced from one another and mate with a plurality of teeth


106


on a drive wheel


104


of the laminating structure


38


. The tractor feed holes


52


permit the liner


42


of the labels


12


to be moved through the laminating structure


38


in a registered fashion.




The labels


12


that are to be laminated must be arranged upon their liner


42


in a repetitive pattern. Each repetition of the pattern may be separated from the previous and subsequent group of labels


12


by perforations


54


in the liner


42


, though these perforations are optional. Two identical groups of laminated labels


10


separated by perforations


54


are depicted in FIG.


1


. Printer registration holes


130


are formed between each group of labels


12


, in this case, at the perforations


54


. The printer registration holes


130


ensure that the printer (not shown) used to print information or designs upon the labels


12


will print the information or designs in the appropriate locations. The perforations


54


in the liner


42


allows the liner


42


underlying each group of labels


12


to be separated from the remaining labels


12


on the liner


42


. It is to be understood that the perforations


54


can be formed in any location between the labels


12


that a user desires.





FIGS. 1 and 3

illustrate the placement of individual sheets of laminate over the respective labels


12


. A number of the labels


12


have security cuts


58


formed into their edges to prevent the labels


12


from being disturbed once applied. The security cuts


58


reduce the label's


12


ability to withstand tensile and shear forces. By dictating that the adhesive bond between the labels


12


and the site to which they are bonded is at least as great as the cohesive strength of the material from which the labels


12


are fashioned, the security cuts


58


ensure that the labels


10


or


12


win tear or otherwise be visibly marred if a person attempts to remove it from the surface to which it has been applied.




With reference to

FIGS. 2 and 3

, the labels


12


are fabricated using well-known devices and techniques that are not themselves part of the present invention. The most common method of fabricating the labels


12


involves a first step of applying the adhesive


46


to the first side of a continuous ribbon of label substrate material


62


. The continuous ribbon of label substrate material


62


is then applied to a continuous ribbon of liner material


42


. The resulting ribbon of label substrate


62


and liner


42


is fed through a stacked die cutting system (not shown) which cuts through the label substrate material


62


to define the perimeter of the label


12


. Blades


64


, which cut through the label substrate material


62


to define the perimeter of the label


12


, are sized to only cut the label substrate material


62


without cutting into the liner


42


. At essentially the same time, blades


66


and


68


cut the tractor feed holes


52


and the security cuts


58


, respectively. Blades


66


and


68


are sized to cut through both the liner


42


and the label substrate material


62


. Yet another set of blades (not shown) cut the perforations


54


through the liner


42


. The label substrate material


62


between the perimeters of the newly cut labels


12


is stripped away. The liner


42


with the labels


12


disposed thereon is generally placed on a roll, though the liner


42


may also be folded along its perforations for storage.




The labels


12


are then printed. Though information or designs may be written or drawn upon the labels


12


, it is preferred to print upon the labels


12


using well known laser printing, resin printing, or thermographic printing techniques. The printer registration holes


130


act in conjunction with sensors within the chosen printer (not shown) that prints information or designs upon the label


12


in order to ensure that the printing is made upon the individual labels


12


disposed upon the liner


42


in its intended locations.




The printed labels


12


disposed upon liner


42


are then loaded into the laminating device


20


for lamination. Though the preferred embodiment of the laminating device


20


describes using rolls of liner


42


with label portions


12


, it is to be understood that the present invention can be modified to accept folded liners


42


without exceeding the scope of this description.




The chassis


22


of the laminating device


20


is comprised of a first frame plate


72


and a second frame plate


74


. The chassis is supported by a stand (not shown) that is affixed to the first frame plate


72


. The second frame plate


74


is secured to the first frame plate


72


in parallel relation to, and spaced apart from, the first frame plate


72


by spacers


76


. The first and second frame plates


72


and


74


together form three pairs of parallel slots


78


,


80


, and


82


. These pairs of parallel slots


78


,


80


, and


82


are sized to slidably receive tensioning structures


84


,


86


, and


88


, respectively. The tensioning structures


84


,


86


, and


88


are themselves arranged to mount a plurality of rollers or drums.




The first frame plate


72


has mounted thereto a laminate supply spindle


26


, a liner take up spindle


28


, a laminate waste take-up spindle


30


, a label supply spindle


32


, and a laminated label take-up spindle


34


. The spindles


26


,


28


,


30


,


32


,


34


cooperate to pass laminating material and printed labels through the laminating structure


38


for lamination. Further, the spindles


26


,


28


,


30


,


32


,


34


are all driven by respective clutch means (not shown) which couple the spindles


26


,


28


,


30


,


32


,


34


to a motor


24


that is mounted between the first and second frame plates


72


and


74


. During the lamination process the clutch means engage in order to drive the spindles


26


,


28


,


30


,


32


,


34


so as to pass the protective film


36


and the labels


12


through the laminating structure


38


.




A roll


92


of protective film


36


disposed upon a liner


42


is received upon the laminate supply spindle


26


such that the liner


42


with the protective film


36


may be unwound from the roll


92


when the laminate supply spindle


26


is rotated in a counterclockwise direction. A second roll


94


is received upon liner take-up spindle


28


in order to wind up the liner


42


after the protective film


36


has been removed therefrom in the laminating process. A third roll


96


is received upon the laminate waste take-up spindle


30


in order to wind up the protective film waste


98


that was not used in the laminating process. The laminating process is such that the waste laminate material


98


forms a strip that may be wound up on the roll


96


in a counter clockwise direction.




Inner laminate feed drum


100


and outer laminate feed drum


102


are rotatively mounted in a fixed relationship to one another upon tensioning structure


84


which itself is slidingly mounted within slot


78


. The inner laminate feed drum


100


and outer laminate feed drum


102


are also connected to the motor


24


by respective clutch means (not shown) so that the drums


100


and


102


may be driven at a predetermined rate of rotation. The inner laminate feed drum


100


rotates in a counterclockwise direction and the outer laminate feed drum rotates in a clockwise direction. Furthermore, the inner and outer laminate feed drums


100


and


102


are in contact with one another such that when the respective drums


100


and


102


are driven, the laminate material on roll


92


may be drawn between the drums


100


and


102


. As can be seen in

FIG. 4

, the liner


42


is separated from the protective film


36


once the film


36


and liner


42


have been drawn through the drums


100


and


102


. The liner


42


from the protective film


36


is then wound up on roll


94


that is mounted upon liner take-up spindle


28


. The protective film


36


is passed around the inner laminate feed drum


100


in a clockwise direction to the point where the inner laminate feed drum


100


meets the toothed drive wheel


104


and the tractor feed holes


52


of the protective film


36


are engaged by the teeth


106


of the drive wheel


104


.




Label supply spindle


32


has mounted thereon a roll of labels


12


disposed upon a liner


42


. The liner


42


having the labels disposed thereon has tractor feed holes


52


formed into its edges that are in registration with the printed labels


12


. The liner


42


having the labels


12


disposed thereon is unwound from the label supply spindle


32


in a counterclockwise direction and passes around a first idler


126


before the tractor feed holes


52


of the liner material


42


are engaged by the teeth


106


of the drive wheel


104


. At the point of contact between the inner laminate feed drum


100


and the toothed drive wheel


104


, the protective film


36


and the liner material


42


having the printed labels


12


disposed thereon are brought into adhesive contact. At this stage the protective film


36


covers the entire surface area of the liner


42


upon which the labels


12


are disposed. The liner


42


having the labels


12


covered by the protective film


36


is then rotated counterclockwise around the toothed drive wheel


104


into contact with the die cutting drum


108


.




The die cutting drum


108


and second idler


110


are rotatively mounted within tensioning structure


88


which is itself slidably mounted within slot


82


between first and second frame plates


72


and


74


. The second idler


110


is in contact with the die cutting drum


108


and is free running so that it can move in response to the die cutting drum


108


. The die cutting drum


108


is constrained to rotate in strict registration with the toothed drive wheel


104


. The means of connecting the drive wheel


104


to the die cutting drum


108


may comprise a set of gears or a toothed belt and sheaves (not shown). The die cutting drum


108


has disposed upon its surface a plurality of laminate cutting blades or knives


112


(seen in

FIG. 3

) that are sized so as to cut through the only the protective film


36


when the knives


112


are brought into contact with the liner


42


having the protective film


36


adhered thereto. As the arrangement of the printed labels


12


upon the liner material


42


may vary from application to application, so too will the arrangement of the knives


112


upon the surface of the die-cutting drum


108


. Each arrangement of printed labels


12


upon the liner material


42


will require a complementary die cutting drum


108


. It is intended that the die-cutting drum


108


be easily removable from the tensioning structure


88


so that it may be altered or replaced should a new cutting arrangement be needed. The laminate cutting blades


112


are arranged upon the surface of the die cutting drum


108


such that the cuts made by the knives


112


are in registration with the printed labels


12


disposed upon the liner


42


. In the preferred embodiment of the present invention the laminate cutting blades


112


of the die cutting drum


108


cut the protective film


36


at an offset to the perimeter of the printed labels


12


of approximately 0.1 inches. This dimension permits the protective film


36


to extend beyond the security cuts


58


formed into the perimeter of the printed labels


12


. It must be understood that the precise dimension of the offset between the perimeters of the protective film


36


and the printed label


12


may be altered to meet the needs of the user, provided that the protective film


36


is cut to a dimension at least as large as the printed label


12


.




As the liner material


42


passes from between the toothed drive wheel


104


and the knives


112


of the die cutting drum


108


, that portion of the protective film


36


not adhered directly to a printed label


12


is wound up by roll


96


received upon laminate waste take-up spindle


30


. The liner


42


having the now laminated labels


10


disposed thereon next passes between an inner label feed drum


122


and the toothed drive wheel


104


before passing around a third idler


118


to be wound up on the laminated label take up roll


120


received upon laminated label take-up spindle


34


.




Inner label feed drum


122


and outer label feed drum


124


are rotatively mounted in a fixed relationship to one another upon tensioning structure


86


which itself is slidingly mounted within slot


80


. The inner label feed drum


122


and outer label feed drum


124


are also connected to the motor


24


by respective clutch means (not shown) so that the drums


122


and


124


may be driven at some predetermined rate of rotation. The inner label feed drum


122


rotates in a clockwise direction and the outer label feed drum


124


rotates in a counterclockwise direction.




An electronic control means (not shown) is electrically coupled to the clutch means that are physically coupled to the spindles


26


,


28


,


30


,


32


,


34


and to the inner laminate feed drum


100


, outer laminate feed drum


102


, toothed drive wheel


104


, die cutting drum


108


, idler


110


, inner label feed drum


122


, and outer label feed drum


124


. The control means also controls the motor


24


. In order to prevent the breakage of the liners


42


or the protective film


36


, it is important to operate the spindles


26


,


28


,


30


,


32


,


34


, inner laminate feed drum


100


, outer laminate feed drum


102


, toothed drive wheel


104


, die cutting drum


108


, idler


110


, inner label feed drum


122


, and outer label feed drum


124


at the same linear speeds. Where the elements of the laminating device


20


are not in synchronization with regard to the linear speed of the liners


42


and the protective film


36


, it is likely that the liners


42


or protective film


36


will be stretched, torn, or bunched up at the point where the velocity changes. Where the protective film is torn or stretched, the lamination is more likely to fail to prevent the label


12


from being damaged by oil or other chemicals. Where the protective film


36


or the liner


42


bunch up, it is also likely that the laminating device will become jammed and therefore inoperable until the bunched material is cleared. The control means electronically coordinates between the plurality of the clutch means in order to ensure that the linear speed of the liners


42


and the protective film


36


is consistent.




The control means also comprises a counting means (not shown) that is capable of keeping track of each label


12


that is laminated by the laminating device


20


. The counting means is preferably a counter that keeps track of the number of rotations of the die-cutting drum


108


and multiplies the number of rotations by the number of labels


12


that are laminated in each rotation of the drum


108


. Another suitable counter may utilize the printer registration holes


130


to keep track of the number of labels that have passed a certain point in the laminating device


20


.




The laminating device


20


is capable of laminating more than 500 labels per minute. At this rate the labels


12


upon the label supply spindle


32


are quickly laminated, requiring that a new roll of labels


12


and protective film


36


be spliced onto the existing liner


42


upon which the labels


12


and film


36


are disposed. Likewise, rolls received upon the liner take up spindle


28


, the laminate waste take-up spindle


30


and the laminated label take-up spindle


34


must occasionally be changed. Initial set up of the laminating device


20


is accomplished by manually threading the respective liners


42


of the protective film


36


and the labels


12


through the laminating structure. Because the initial set up is time consuming and can represent a significant amount of down time, it is preferred to splice new rolls of protective film


36


and labels


12


onto the exhausted rolls before all of the liners of the film


36


and the labels


12


have been drawn through the laminating structure


38


. A splicing aid (not shown) comprises a flat surface having disposed thereon a plurality of pins that mate with the tractor feed holes of the new and old liners


42


. Typically, tape is used to connect the old and new liners


42


once they have been aligned.




The foregoing is considered as illustrative only of the principles of the invention. Furthermore, since numerous modifications and changes will readily. occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.
