Description




BACKGROUND OF THE INVENTION




The present invention generally relates to ink jet printer apparatus and methods therefor and more particularly relates to an ink jet printer system for printing an image on a web overlaying a removable substrate, and method of assembling the printer system.




It is known to print colorful images on woven and unwoven textiles or fabrics such as cotton, wool, silk, synthetics, and the like prior to the fabrics being cut and sewn. Of course, the fabrics are cut and sewn to provide articles for everyday use, such as clothing, towels, upholstery and other articles.




Various printing techniques are used to produce the images that appear on the fabric. One technique is to use the well-known process of screen printing, wherein a screen serving as a stencil and having a predetermined mesh count is coated with ink of a desired color. It is the back of the screen that is coated with ink. The article to be screen printed is then placed on the front of the screen and a squeegee blade is pressed against the back of the screen to work the ink into the article. In this manner, the image is printed onto the article.




However, use of screen printing has several disadvantages. For example, screen printing is unsuitable for quickly changing images to be printed in order to keep-up with changes in consumer taste. Also, time required to set-up or construct a particular screen stencil and mix the desired ink color in order to print particular image makes screen printing not cost-effective for small quantity production runs. In other words, screen printing is not cost-effective for a large number of small production runs because of the increased frequency of screen set-ups.




Another well-known technique for printing images on fabrics is use of a plate roller having the image engraved on the plate in reverse relief In this regard, ink of a desired color is applied to the plate and the plate is then rolled against the fabric to be printed in order to form the image on the fabric. However, use of the plate roller technique is relatively expensive because the plate roller technique typically uses a rotogravure printing process, which requires fabrication of an intaglio plate prepared by photographic methods. Of course, an intaglio plate is an engraving etched deeply into a surface of a hard material, which is typically metal. Also, time required to engrave the plate in order to print a particular image makes plate roller printing not cost-effective for small quantity production runs. In other words, plate roller printing is not cost-effective for smaller production runs because each article is printed from one engraving of the plate and smaller production runs would increase frequency of engraving and production set-ups.




Therefore, the commercial fabric printing industry is shifting from screen printing and plate roller printing of fabrics to ink jet printing of fabrics. Ink jet printing of fabrics offers several advantages over screen printing and plate roller printing. That is, ink jet printing allows immediate changes in color and design of an image in order to rapidly adjust to consumer tastes. This is so because ink channels formed in the ink jet print head can be selectively enabled depending on the particular image to be printed at that moment. In other words, ink jet printing is well-suited to small production runs as well as large production runs because ink jet printing does not require time-consuming and expensive fabrication and deployment of a screen stencil or an engraved plate every time the design of the image is changed.




However, although not all ink jet printers require fabrics to be stiffened, it has been observed that fabric to be printed by an ink jet printer typically needs stiffening in order to properly feed through the printer's feeding mechanism. This is so because the fabric is inherently quite flexible in both the longitudinal and transverse directions. This inherent flexibility of the fabric may result in misalignment of the fabric or even “jamming” of the fabric in the printer as the fabric feeds through the printer. Misalignment of the fabric produces images of inconsistent quality and “jamming” of fabric in the printer causes the printer to cease operation, at least until the “jammed” fabric is cleared. Therefore, a common practice in the art of ink jet printing of fabrics is to provide a substrate, such as a relatively stiff paper backing material, coupled to the fabric. This backing material may be adhered to the fabric by a suitable adhesive. The backing material is selected for its thickness and stiffness, such that the fabric with backing material has sufficient stiffness in the longitudinal and transverse directions to properly feed through the printer.




However, this solution to the previously mentioned “stiffness” problem in turn gives rise to another problem in the art. That is, it is preferable to remove the relatively stiff backing material from the fabric prior to the fabric being cut and sewn. In the prior art, removal of the backing material is accomplished manually. That is, typically an attendant assigned to operate the printer manually grasps the fabric and backing material after printing and then peels the backing material from the fabric. The backing material is discarded by the attendant. Hence, time and labor are expended to remove the backing material. Therefore, it is desirable to avoid manual removal of the backing material in order to save time and labor.




Apparatus and methods for ink jet printing of textiles having a removable backing layer are known. Such an apparatus and method are disclosed by U.S. Pat. No. 6,071,368 titled “Method And Apparatus For Applying A Stable Printed Image Onto A Fabric Substrate” issued Jun. 6, 2000 in the name of Melissa D. Boyd, et al. and assigned to the assignee of the present invention. The Boyd, et al. patent discloses an ink transfer sheet including a backing layer, a detachable release layer on the backing layer, and an ink receiving layer on the release layer. According to the Boyd, et al. patent, the backing layer provides support for the other layers while the release layer is used to adhere the ink receiving layer and printed image onto a fabric substrate. The ink receiving layer is formulated to allow adhesion and/or absorption of ink materials thereon so that a defined printed image can be effectively transferred. In this regard, once the ink composition is delivered to the ink receiving layer of the transfer sheet, the transfer sheet is placed on and against the selected fabric substrate so that the ink receiving layer and the printed image are in physical contact with the substrate. Heat is applied to the transfer sheet to cause the release layer and ink receiving layer to adhere to the fabric substrate. After or during application of heat, the backing layer is removed (e.g., by physical detachment or “peeling”) from the ink transfer sheet. The release layer and receiving layer are left on the fabric substrate so that the printed image is transferred to the fabric substrate. However, although the Boyd, et al. patent discloses removing the backing layer from the fabric substrate, the Boyd, et al. patent does not disclose structure to accomplish this result and therefore does not disclose a solution to the problem of manual removal of the backing layer.




Another ink jet printing apparatus and method for fabric printing are disclosed by U.S. Pat. No. 6,254,231 B1 titled “Ink-Jet Textile Printing Ink And Ink-Jet Printing Process And Instrument Making Use Of The Same” issued Jul. 3, 2001 in the name of Mariko Suzuki, et al. The Suzuki, et al. patent discloses an ink-jet printing process that includes the steps of applying an ink to a cloth in accordance with an inkjet system, subjecting the cloth to a reactive fixing treatment, and then washing the cloth thus treated to remove unreacted dye. However, the Suzuki, et al. patent does not disclose that the fabric has a backing material and therefore does not disclose a solution to the problem of manually removing the backing material.




Hence, a problem in the art is the practice of manual removal of the backing material from fabric printed by an ink jet printer.




Therefore, what is needed is an ink jet printer system for printing an image on a web overlaying a removable substrate, and method of assembling the printer system, the printer system being capable of removing the substrate from the web.




SUMMARY OF THE INVENTION




The present invention generally resides in an ink jet printer system for printing an image on a web overlaying a removable substrate, comprising: a print head for jetting ink onto the web; a feeder mechanism associated with the print head for feeding the web and substrate past the print head; and a first work station associated with the feeder mechanism for removing the substrate.




According to an aspect of the present invention, the ink jet printer system comprises an ink jet print head for jetting ink onto the web to form an image on the web. Coupled to the web is a substrate. A feeder mechanism is coupled to the print head for feeding the web and substrate past the print head during printing. A first roller is aligned with the feeder mechanism and is adapted to engage the substrate for mechanically removing the substrate from the web. A second roller is aligned with the first roller, the second roller being adapted to layer a covering onto the printed image as the first roller removes the substrate from the web. The web with layered covering defines a layered web. The covering is provided to protect the printed image from damage during subsequent handling and to prevent “bleed through” of the image, as discussed presently. In addition, a third roller is aligned with the second roller for supplying the covering to the second roller. Moreover, a steaming core is provided to bundle-up the layered web, so that a steaming roll is defined thereby. A steam generator receives the steaming roll and generates steam for fixing the ink to the layered web. The previously mentioned covering separates successive layers of the web when bundled in the form of the steaming roll. In this manner, ink from the top surface of the web in one layer of the steaming roll will not contact the bottom surface of the web in an adjacent layer of the steaming roll. Further, the covering is removed from the layered web and a washer is preferably disposed to then wash the web for removing unfixed ink from the web. Also, a hot-air blower directs heated air onto the web for drying the web. A take-up reel may also be provided to engage the web and wrap the web thereabout in order to package the web for shipment.




A feature of the present invention is the provision of a first roller aligned with the feeder mechanism and adapted to engage the substrate for mechanically removing the substrate from the web.




An advantage of the present invention is that use thereof decreases total printing time, labor and expense.




Another advantage of the present invention is that use thereof decreases likelihood of damage to the web, which in turn decreases wastage.











These and other features and advantages of the present invention will become apparent to those skilled in the art upon a reading of the following detailed description when taken in conjunction with the drawings wherein there are shown and described illustrative embodiments of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




The present invention will be directed in particular to elements forming part of, or cooperating more directly with, apparatus in accordance with the present invention. It is to be understood that elements not specifically shown or described may take various forms well known to those skilled in the art.




Therefore, referring to

FIGS. 1

,


2


,


3


and


4


, there is shown an ink jet printer system, generally referred to as


10


, for printing an image


15


on a web


20


overlaying a removable substrate


30


. By way of example only and not by way of limitation, web


20


may be a textile or fabric such as cotton, wool, silk or synthetic textile material. However, although the description herein is with reference to web


20


being a textile or fabric, it will be appreciated that web


20


may be any suitable material that overlays a removable substrate and upon which image


15


is to be formed. Moreover, substrate


30


is selected so that it is sufficiently strong and stiff in order that web


20


moves effortlessly through printer system


10


in a manner disclosed more fully hereinbelow. In this regard, substrate


30


may have a thickness of about 0.04 to 0.16 mm and be made of any suitable material such as paper, polyester, cellophane, nylon, or other material.




Referring to

FIGS. 1

,


2


,


3


,


4


and


5


, substrate


30


with web


20


overlaid thereon is presented to a print head


40


in the form of a roll


50


wound about a rotatable spindle


60


. The spindle


60


may be rotated by means of a first motor


65


. Prior to start of printing, an end portion of web


20


and substrate


30


are positioned adjacent to print head


40


by any convenient means well known in the art, such as manually or by mechanical means (not shown). Moreover, print head


40


itself is preferably a thermal ink jet print head having a plurality of aligned ink channels


70




a


,


70




b


and


70




c


formed therein (only three of which are shown). Of course, it may be appreciated that print head


40


may be a piezoelectric print head. Each channel


70




a


,


70




b


and


70




c


terminates in a channel orifice


7






2




a,


72




b


and


72




c


, respectively. In addition, each ink channel


70




a


,


70




b


and


70




c


preferably contains a differently colored ink


75




a


,


75




b


and


75




c


, respectively, consisting of a dye or pigment dispersion. In this regard, inks


75




a


,


75




b


and


75




c


may possess a red, blue and yellow color, respectively, if desired.




Referring again to

FIGS. 1

,


2


,


3


,


4


and


5


, during printing, web


20


and substrate


30


are supported and fed past print head


40


by a feeder mechanism. For example, the feeder mechanism may be a generally cylindrical platen


80


preferably rotatable on an axle


85


and positioned opposite orifices


72




a


,


72




b


and


72




c


. Axle


85


may be rotated by means of a second motor


87


. In addition, a tensioner, such as a capstan roller


89


, may be provided to engage web


20


and substrate


30


for tensioning web


20


and substrate


30


. Tensioning web


20


and substrate


30


in this fashion reduces risk of fouling (i.e., “jamming”) of web


20


and substrate


30


between print head


40


and platen


80


. During operation of thermal ink jet print head


40


, a multiplicity of ink drops


90


(only one of which is shown) are selectively jetted from orifices


72




a


,


72




b


and


72




c


and onto web


20


in order to form image


15


. Ink drops


90


are preferably jetted onto web


20


by selective explosive formation of a vapor bubble (not shown) in channels


70




a


,


70




b


and/or


70




c


to selectively jet ink drops


90


from channels


70




a


,


70




b


and/or


70




c


. As well-known in the art, the vapor bubble is formed due to application of an electrical pulse to a plurality of resistors in respective fluid communication with each of inks


75




a


,


75




b


and


75




c


. The principal of operation of such a thermal ink jet print head is disclosed more fully in U.S. Pat. No. 4,490,728 titled “Thermal Ink Jet Printer” issued Dec. 25, 1984 in the name of John L. Vaught, et al. and assigned to the assignee of the present invention, the disclosure of which is hereby incorporated by reference.




As best seen in

FIG. 3

, print head


40


may threadably engage a belt drive


100


rotatable by means of a third motor


110


. As belt drive


100


rotates, print head


40


will traverse web


20


while channels


70




a


,


70




b


and/or


70




c


selectively jet ink drops


90


onto web


20


. Of course, platen


80


is rotated to advance web


20


each time print head


40


traverses web


20


and jets ink drops


90


onto web


20


. In this manner image


15


is formed on web


20


in a raster-like fashion. Although belt drive


100


is shown for enabling print head


40


to traverse web


20


, other motive means may be used, such a screw-drive mechanism (not shown).




Alternatively, print head


40


may be a piezoelectric print head rather than a thermal ink jet print head, if desired. In this regard, such a piezoelectric print head also includes channels


70




a/b/c


terminating in channel orifices


72




a/b/c


, respectively. However, in this instance, print head


40


is made of a piezoelectric material and ink is selectively jetted from orifices


72




a/b/c


by means of an electric pulse selectively applied to the piezoelectric material comprising each channel


70




a/b/c


. Due to the inherent nature of piezoelectric material, walls of selected ones of channels


70




a/b/c


inwardly move when the walls are electrically stimulated. As the walls of the selected channels respond to the electric stimulus by inwardly moving, ink drops


90


are jetted from their corresponding orifices. A representative piezoelectric print head is disclosed in U.S. Pat. No. 6,193,343 titled “Driving Method Of An Ink Jet Printhead” issued Feb. 27, 2001 in the name of Norigoe, et al.




As previously mentioned, it is important to remove (i.e., peel) the relatively stiff substrate


30


from web


20


. This is important in order to prepare the fabric material of web


20


for cutting and sewing. In the prior art, removal of the substrate


30


(i.e., backing material) is accomplished manually. That is, typically an attendant assigned to operate printer system


10


manually grasps web


20


(e.g., fabric) and substrate


30


(i.e., backing material) after printing and then peels substrate


30


from the entirety of web


20


. However, this technique of removing substrate


30


results in increased total printing time, labor and expense. Moreover, this technique of removing substrate


30


increases likelihood of damage to fabric web


20


, which in turn increases wastage. Consequently, it is desirable to avoid manual removal of substrate


30


in order to save time, labor and expense and to avoid damage to fabric web


20


.




Therefore, referring to

FIGS. 1

,


2


and


6


A, aligned with platen


80


is a first work station, such as a generally cylindrical and rotatable first roller


120


, for mechanically removing (i.e., peeling) substrate


30


from web


20


. First roller


120


may be coupled to a fourth motor


130


for rotating first roller


120


. The attendant assigned to operate printer system


10


threads web


20


and substrate


30


from platen


80


by any convenient means such as manually or mechanically. The attendant then separates a diminimus portion of substrate


30


from web


20


and wraps that portion of substrate


30


at least partially around first roller


120


. For example, the attendant may wrap that portion of substrate


30


approximately one to one and one half times around first roller


120


, if desired. That is, the attendant need only peel and wrap a sufficient amount of substrate


30


around first roller


120


so that substrate


30


avoids slipping on first roller


120


as first roller rotates by means of fourth motor


130


. In this manner, as first roller


120


is caused to rotate, first roller


120


will mechanically peel the remainder of substrate


30


from web


20


after web


20


and substrate


30


feed past print head


40


.




Referring again to

FIGS. 1

,


2


and


6


A, aligned with first roller


120


is a second work station, such as a generally cylindrical and rotatable second roller


140


. As described more fully hereinbelow, second roller


140


is adapted to layer a covering


145


onto web


20


as second roller


140


rotates and as first roller


120


peels substrate


30


from web


20


. Second roller


140


may be coupled to a fifth motor


150


for rotating second roller


140


. The attendant assigned to operate printer system


10


threads the portion of web


20


, from which substrate has been separated, into engagement or contact with second roller


140


, as shown. The attendant may thread that portion of web


20


into engagement with second roller


140


by any convenient means, such as manually or mechanically.




Turning now to

FIG. 6B

, there is shown a second embodiment first roller


155


. Second embodiment first roller


155


is substantially similar to first embodiment first roller


120


, except that second embodiment first roller


155


includes an elongate knife edge or blade


157


having a sharp edge portion


159


. The sharp edge portion


159


is capable of engaging the interface between web


20


and substrate


30


for easing separation of web


20


from substrate


30


.




Returning to

FIGS. 1

,


2


and


6


A, aligned with second roller


140


is a third work station, such as a generally cylindrical and rotatable third roller


160


having a supply of the covering


145


wound thereabout. The purpose of third roller


160


is to supply covering


145


to second roller


140


as third roller


160


rotates, such as by operation of a sixth motor


170


. In this regard, the attendant grasps a free end of covering


145


and threads the free end of covering


145


into engagement or contact with second roller


140


such that covering


145


is interposed between web


20


and second roller


140


. In this manner, covering


145


is caused to layer web


20


as web


20


and covering


145


engage second roller


140


. Thusly, web


20


with covering


145


layered thereon defines a layered web


175


. The purpose of covering


145


is to cover printed image


15


, so that image


15


is not damaged during subsequent handling and to prevent “bleed through” of the ink forming image


15


. That is, covering


145


separates successive layers of web


20


when web


20


and covering


145


are bundled-up (rolled-up) into a “steaming roll” prior to steaming. In this manner, ink from the top surface of web


20


in one layer of the steaming roll will not contact the bottom surface of the web in an adjacent layer of the steaming roll. Covering


145


may be paper or plastic.




Referring to

FIGS. 1 and 2

, aligned with second roller


140


is a bundling station, such as a solid and generally cylindrical steaming core


180


, which supports a flexible mesh material, such as a cylindrical wire mesh


185


having a relatively low mesh count. Mesh


185


defines openings (not shown) to allow steam therethrough, for reasons disclosed presently. The attendant threads layered web


175


into engagement with mesh


185


and wraps a portion of layered web


175


about mesh


185


. The attendant may wrap the portion of layered web


175


about one and one half turns around mesh


185


, so that layered web


175


avoids slipping on mesh


185


as steaming core


180


is rotated. As steaming core


180


is rotated, such as by a seventh motor


190


, layered web


175


will further wrap around mesh


185


. Thus, it may be appreciated from the description hereinabove that mesh


185


is adapted to engage and bundle-up layered web


175


, so that a steaming roll


200


is defined thereby.




Referring again to

FIGS. 1 and 2

, a controller


205


is electrically connected to first motor


65


, second motor


87


, third motor


110


, fourth motor


130


, fifth motor


150


, sixth motor


170


and seventh motor


190


for synchronous rotation of motors


65


/


87


/


110


/


130


/


150


/


170


/


190


. Controller


205


may be any suitable controller, such as is available from AmeriMex Motor & Controls, Incorporated located in Houston, Tex. (USA). Alternatively, only seventh motor


190


may be provided, if desired, and the other motors eliminated for reducing costs. In this case, seventh motor


190


will have been selected so as to possess sufficient torque to pull web


20


, substrate


30


and covering


145


.




Still referring to

FIGS. 1 and 2

, a fixing station, such as a steam generator


210


, is disposed to sealingly receive steaming roll


200


therein. In this regard, steam generator


210


is adapted to generate and deliver, such as through a plurality of steam nozzles


215


, superheated steam permeating steaming roll


200


and its associated web


20


for fixing the ink to web


20


. The superheated steam may have a temperature of approximately 100° C. to 110° C. and steaming roll


200


may reside in steam generator


210


a predetermined time depending on the web material and composition of ink. Steam generator


210


itself has a cover


220


rotatable about a hinge


225


for opening and closing steam generator


210


, so that steaming roll


200


may be received into and extricated from steam generator


210


.




Referring yet again to

FIGS. 1 and 2

, steaming roll


200


is removed from steam generator


210


by any convenient means such as manually or mechanically. Layered web


175


is then preferably unwound from steaming roll


200


. As layered web


175


is unwound from steaming roll


200


, covering


145


is removed from layered web


175


, such as by means of a de-covering station or fourth roller


227


rotatable by a seventh motor (not shown). In this regard, the attendant peels a diminimus portion of covering


145


away from layered web


175


and wraps that portion of covering


145


around fourth roller


227


. The attendant then directs the bare web


20


through a washing station


230


that washes unfixed ink from bare web


20


. Thus, it may be understood from the description hereinabove, that removal of covering


145


from layered web


175


is accomplished in a manner substantially similar to removal of substrate


30


from web


20


. In other words, covering


145


is preferably removed from layered web


175


prior to washing, thereby defining bare web


20


. Moreover, a drying station, such as a hot-air blower generally referred to as


240


, is disposed to direct a column of heated air onto bare web


20


for drying bare web


20


after bare web


20


is washed. Blower


240


may comprise an air pump


250


for blowing air across a resistance heater


260


in order to supply the heated air to bare web


20


. Alternatively, bare web


20


may be left to naturally air-dry. In addition, a packaging station, such as a take-up reel


270


, is aligned with washer


230


and is adapted to engage bare web


20


for wrapping bare web


20


around take-up reel


270


. In this manner, layered web


175


is packaged for shipment to a suitable facility for cutting and sewing into articles for everyday use, such as clothing, towels, upholstery and other articles.




It may be understood from the description hereinabove that an advantage of the present invention is that use thereof decreases total printing time, labor and expense. This is so because substrate


30


is mechanically (i.e., automatically) removed from web


20


rather than being manually removed from web


20


and also because layered web


175


is formed automatically.




It may be further understood from the description hereinabove, that another advantage of the present invention is that use thereof decreases likelihood of damage to web


20


, which in turn decreases wastage. This is so because manual manipulation of web


20


and substrate


30


, along with the associated human error, is reduced.




While the invention has been described with particular reference to its preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements of the preferred embodiments without departing from the invention. For example, a radiant heater may be substituted for hot-air blower


240


.




Therefore, what is provided is an ink jet printer system for printing an image on a web overlaying a removable substrate, and method of assembling the printer system, the printer system being capable of removing the substrate from the web.
