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.
