- a liquid e.g., a liquid mixture of ink and thinner
- Automated printing systems are in widespread use in a host of industries.
- the number of types of printing systems is almost as great as the number of industries in which these systems are used.
- pad printing system One type of printing system that operates in a fully automatic or near fully automatic mode is a pad printing system. These systems are used to apply high quality print (e.g., indicia) on flat as well as non-flat surfaces.
- pad printing systems can be used to print logos on cellular telephone covers, game balls (e.g., golf balls). It will be appreciated that such printing must be carried out, not only on a spherical surface, but on a surface that is formed with dimples as well.
- Conventional pad printing systems use a deformable pad which receives ink, transferred as an image, from a flat cliché plate.
- the plate has an engraving or etching of the indicia formed therein.
- Ink is transferred from a liquid supply assembly to the cliché plate, and fills into the etched areas.
- the deformable pad is then pressed onto the plate and ink within the liquid is picked up by the pad.
- the image is then transferred to the curved surface which is to be printed.
- an inverted cup containing a quantity of printing ink is used to apply the ink to the cliché plate.
- the cup and cliché plate are moved relative to each other following each ink transfer operation.
- a doctor blade is fitted to the cup to traverse along the cliché plate and "wipe" excess ink from the cliché plate. This assures that ink is left behind in the etching but does not build up on the plate, inside or outside of the etched areas.
- a cup insert according to the preamble of claim 1 is disclosed in document US 2007/0157833 A1 .
- the present invention provides a new and unique liquid supply assembly and a method according to claims 1 and 7 employing a reusable cup including a reusable liquid reservoir, a disposable cup insert including a temporary liquid reservoir for holding a liquid within the reusable liquid reservoir, and a scraping element including a conduit in liquid communication with the temporary liquid reservoir of the disposable cup insert.
- This liquid assembly is designed to be used by a printing system of the type in which the reusable cup is secured by the printer system whereby the liquid held by the temporary liquid reservoir of the disposable cup insert can be deposited by the conduit in a receiving region on a plate and any excess of the liquid in the receiving region can be scraped from the plate by the scraping element.
- the disposable cup insert includes a hollow reservoir body having an open outlet and a closed base defining the temporary liquid reservoir.
- the closed base has a flexible material composition to facilitate an expansion of the temporary liquid reservoir in response to an increase in a gas pressure exerted by the liquid on the temporary liquid reservoir.
- the open outlet includes a seal enclosing the conduit of the scraping element.
- the open outlet includes a hinge facilitating movement of the scraping element relative to the disposable cup insert.
- FIG. 1 illustrates a portion of an exemplary pad printer 10 including a frame 11 having a reciprocating printing pad 12 mounted thereto.
- Printing pad 12 is a deformable pad onto which ink is transferred, and from which the ink is further transferred to the object to be imprinted.
- a typical printing pad 12 is formed from a resilient, low permeability material such as silicone rubber or the like.
- a cliché plate 20 which has the artwork in the form of an engraving or etching
- a liquid supply assembly 30 which is secured by a cup gripping mechanism ("CGM") 13 of pad printer 10 whereby cliché plate 20 and liquid supply assembly 30 can be reciprocated relative to one another to supply a liquid held by the liquid supply assembly 30 to cliché plate 20 (e.g., ink from an ink/thinner liquid mixture).
- liquid supply assembly 30 includes a reusable cup 40, a disposable cup insert 50 inserted within reusable cup 40, and a scraping element in the form of a doctor ring 60.
- cup gripping mechanism 13 secures reusable cup 40 as would be appreciated by those having ordinary skill in the art whereby, as the liquid supply assembly 30 and/or cliché plate 20 are being translated in a horizontal direction, liquid held by disposable cup insert 50 can be deposited in a receiving region on cliché plate 20 and any excess of the liquid can be scraped from cliché plate 20 by doctor ring 60 to thereby leave liquid in the receiving region only of cliché plate 20.

Description
- This application is a continuation-in-part of
U.S. Patent Application No. 13/738,667, which was filed on 10-January-2013 U.S. Patent Application No. 11/617,402, which was filed on 28-December-2006 U.S. Provisional Patent Application No. 60/754,717, which was filed on 29-December-2005 - The present invention relates to liquid supply assemblies for printers. More particularly, the present invention relates to a disposable cup insert as a temporary reservoir designed to hold a liquid (e.g., a liquid mixture of ink and thinner) used in a pad printing and decorating process.
- Automated printing systems are in widespread use in a host of industries. The number of types of printing systems is almost as great as the number of industries in which these systems are used.
- One type of printing system that operates in a fully automatic or near fully automatic mode is a pad printing system. These systems are used to apply high quality print (e.g., indicia) on flat as well as non-flat surfaces. For example, pad printing systems can be used to print logos on cellular telephone covers, game balls (e.g., golf balls). It will be appreciated that such printing must be carried out, not only on a spherical surface, but on a surface that is formed with dimples as well.
- Conventional pad printing systems use a deformable pad which receives ink, transferred as an image, from a flat cliché plate. The plate has an engraving or etching of the indicia formed therein. Ink is transferred from a liquid supply assembly to the cliché plate, and fills into the etched areas. The deformable pad is then pressed onto the plate and ink within the liquid is picked up by the pad. The image is then transferred to the curved surface which is to be printed.
- To re-ink the pad, in a commonly used arrangement, an inverted cup containing a quantity of printing ink is used to apply the ink to the cliché plate. To apply a new coating of ink to the cliché plate, the cup and cliché plate are moved relative to each other following each ink transfer operation. A doctor blade is fitted to the cup to traverse along the cliché plate and "wipe" excess ink from the cliché plate. This assures that ink is left behind in the etching but does not build up on the plate, inside or outside of the etched areas.
- Currently, the cup is typically cleaned after each use of the cup in applying a new coating of ink to the cliché plate. Such cleaning can be costly in terms of time, labor and materials. Accordingly, there is a need for a liquid supply assembly for a printing system that minimizes, if not eliminates, a cleaning requirement of the reusable cup after each of use of the cup in applying a new coating of ink to the cliché plate.
- A cup insert according to the preamble of
claim 1 is disclosed in documentUS 2007/0157833 A1 . - The present invention provides a new and unique liquid supply assembly and a method according to
claims 1 and 7 employing a reusable cup including a reusable liquid reservoir, a disposable cup insert including a temporary liquid reservoir for holding a liquid within the reusable liquid reservoir, and a scraping element including a conduit in liquid communication with the temporary liquid reservoir of the disposable cup insert. This liquid assembly is designed to be used by a printing system of the type in which the reusable cup is secured by the printer system whereby the liquid held by the temporary liquid reservoir of the disposable cup insert can be deposited by the conduit in a receiving region on a plate and any excess of the liquid in the receiving region can be scraped from the plate by the scraping element. - The disposable cup insert includes a hollow reservoir body having an open outlet and a closed base defining the temporary liquid reservoir.
- In a first form of the disposable cup insert, the closed base has a flexible material composition to facilitate an expansion of the temporary liquid reservoir in response to an increase in a gas pressure exerted by the liquid on the temporary liquid reservoir.
- The open outlet includes a seal enclosing the conduit of the scraping element.
- In another embodiment of the disposable cup insert, the open outlet includes a hinge facilitating movement of the scraping element relative to the disposable cup insert.

In this embodiment, seal 56 serves as the sole or primary seal. An orientation of the elements in such a fashion allows ink to flow substantially unimpeded to the edge of a scraping element, and allows better ink coverage of the image. In one embodiment, thereservoir body 51 includes aninner bottom portion 70 and an outerlower portion 71 separated by a recessed portion, such that the recessed portion is configured to mate with a conduit body, and theinner bottom portion 70 and an outerlower portion 71 are substantially collinear. In another embodiment, thereservoir body 51 includes aninner bottom portion 70 and an outerlower portion 71 separated by a recessed portion, such that the recessed portion is configured to mate with a conduit body, and theinner bottom portion 70 and an outerlower portion 71 are not substantially collinear. In another embodiment, the channeled seat includes a recessed portion separating an inner portion and an outer portion such that a lower surface of the inner portion is not collinear with a lower surface of the outer portion and each of the inner portion, recessed portion, and outer portion is configured to mate with a reservoir body holding ink. - As shown in
FIGS. 12 and13 , the flange of theopen outlet 42 is again in the form of the channeledseat 46 of thedisposable cup insert 50. A sealingmaterial 1200 is loaded into the channeledseat 46. Thedisposable cup insert 50 extends between a closed base orend 1202 and an oppositefirst end 1204 having theopen outlet 42 through which ink held in the reservoir of thedisposable cup insert 50 is dispensed. This sealingmaterial 1200 can be loaded into the channeledseat 46 prior to placing the scraping element ordoctor blade 60 into the channeledseat 46. Alternatively, the scrapingelement 60 can be positioned into the channeledseat 46 and the sealingmaterial 1200 can be loaded into the channeledseat 46 afterward (e.g., at least partially around the scraping element 60). - The sealing
material 1200 is a fluid material or compound when the sealingmaterial 1200 is placed into the channeledseat 46. In one aspect, the sealingmaterial 1200 may be a liquid or get material when loaded into the channeledseat 46. For example, the sealingmaterial 1200 may be a fluid (e.g., uncured) silicone material, a caulk material, or another material that is capable of flowing at room temperature (e.g., 20 degrees Celsius). The scrapingelement 60 may then be at least partially placed into thefluid sealing material 1200. Thefluid sealing material 1200 is then cured into a flexible material that forms a seal between the scrapingelement 60 and thedisposable cup insert 50 in the channeledseat 46. Alternatively, thefluid sealing material 1200 may cure into a rigid or semi-rigid material that forms a seal between the scrapingelement 60 and thedisposable cup insert 50 in the channeledseat 46, as shown inFIG. 13 . - The
disposable cup insert 50 may then be positioned in thereusable cup 40 with the sealingmaterial 1200 and thescraping element 60 in the channeledseat 46 of thedisposable cup insert 50. Depending on howmuch sealing material 1200 is placed into the channeledseat 60, where the scrapingelement 60 is positioned in the channeledseat 46 relative to the sealingmaterial 1200 in the channeledseat 60, the width of the channeledseat 46, the width of the scrapingelement 60, the sealingmaterial 1200 may extend between the scrapingelement 60 and thedisposable cup insert 50 along all threesides disposable cup insert 50 in the channeled seat 46 (in the perspective ofFIGS. 12 and13 ). Alternatively, the sealingmaterial 1200 may extend between the scrapingelement 60 and thedisposable cup insert 50 along fewer than all three sides of thedisposable cup insert 50 within the channeledseat 46. For example, from the perspective ofFIGS. 12 and13 , the sealingmaterial 1200 may only be disposed beneath the scrapingelement 60, to the right of the scrapingelement 60, to the left of the scrapingelement 60, or a combination of two of these locations (e.g., beneath and to the left of the scrapingelement 60, beneath and to the right of the scrapingelement 60, or to the right and left of the scraping element 60). - Placing the sealing
material 1200 in the channeledseat 46 provides an improved seal between the scrapingelement 60 and thedisposable cup insert 50. The sealingmaterial 1200 can physically and/or chemically bond with thedisposable cup insert 50 and or thescraping element 60 to improve the seal therebetween. Additionally, use of a sealingmaterial 1200 that is flexible after curing can prevent cracking of tearing of thedisposable cup insert 50. Extended use of thedisposable cup insert 50 can result in thescraping element 60 tearing or cracking thedisposable cup insert 50 in or near the channeledseat 46. The flexible cured sealingmaterial 1200 can prevent this tearing or cracking for an extended period of time relative to thescraping element 60 being placed into the channeledseat 46 without the sealingmaterial 1200, thereby extending the time period over which thedisposable cup insert 50 can be used. - In another embodiment, the sealing
material 1200 may be positioned between other components. For example, the sealingmaterial 1200 may be positioned between two or more of the reusable hollow body, the disposable cup insert, and/or the scraping element described herein. -
FIG. 14 is a flowchart of amethod 1400 according to the invention for sealing a scraping element to a disposable cup insert. Themethod 1400 is used to seal thescraping element 60 with thedisposable cup insert 50. At 1402, a sealing material is placed into a channeled seat of the disposable cup insert. The sealingmaterial 1200 is placed into the channeledseat 46 of thedisposable cup insert 50 while the sealingmaterial 1200 is in a fluid state. At 1404, the scraping element is placed into the channeled seat of the disposable cup insert. The scrapingelement 60 is placed into the channeledseat 46 of thedisposable cup insert 50 and at least partially into the sealingmaterial 1200. Alternatively, the scrapingelement 60 may be placed into contact with, but not into, the sealingmaterial 1200. At 1406, the sealing material forms a seal between the scraping element and the disposable cup insert within the channeled seat of the disposable cup insert. For example, the sealingmaterial 1200 may cure and bond (e.g., chemically and/or physically bond) with thedisposable cup insert 30 and/or thescraping element 60 to form a flexible, semi-rigid, or rigid body that forms a seal between the scrapingelement 60 and thedisposable cup insert 50 in the channeledseat 46 of thedisposable cup insert 50. - The previously disclosed flanged embodiments of
open outlet 52 ofdisposable cup insert 50 can also have a flexible material composition to facilitate an expansion ofliquid reservoir 54 as indicated by the dashed outline ofreservoir body 51. Furthermore,disposable cup insert 50 may be supported byreusable cup 40 by any other technique (e.g., friction and snaps). - Referring to
FIGS. 1-13 , the embodiments described herein provide many advantages of the liquid supply assembly including, but not limited to, a disposable cup insert nesting in a reusable cup to thereby hold liquid away from the reusable cup while permitting the normal use of the reusable cup by a pad printing system. The result is a significant reduction in labor, material and costs associated with a cleaning of the reusable cup. - Furthermore, for the sealing configuration embodiment shown in
FIG. 9 , a suitable compressive engagement betweencliché plate 20 anddoctor blade 60 can be maintained over the circumference ofdoctor blade 60 irrespective of imperfections in the surface contact betweencliché plate 20 anddoctor blade 60 and irrespective of the pressurized environment withinliquid reservoir 54. -
FIG. 10 illustrates a further advantage of the present invention. Specifically, a blackliquid supply assembly 30A includes a disposable cup insert 50A inserted into reusableliquid reservoir 44 ofreusable cup 40 with its temporaryliquid reservoir 54A holding a black ink/thinner liquid mixture 80 withinreusable liquid reservoir 44. As such, black ink held by temporaryliquid reservoir 54A can be deposited in a receiving region ofcliché plate 20A and any excess of the black ink in the receiving region can be scraped fromcliché plate 20A bydoctor ring 60. - Upon a conclusion of a printing use of the black ink deposited in the receiving region of
cliché plate 20A, another batch of the black ink/thinner liquid mixture 80 can be held by temporaryliquid reservoir 54A withinreusable liquid reservoir 44 for purposes of depositing more block ink in the receiving region ofcliché plate 20A to thereby use the new batch of black ink in another printing process. Alternatively, blackliquid supply assembly 30A can be disassembled with a removal of disposable cup insert 50A from reusableliquid reservoir 44, and a redliquid supply assembly 30B can be assembled with a disposable cup insert 50B being inserted into reusableliquid reservoir 44 ofreusable cup 40 with its temporaryliquid reservoir 54B holding a red ink/thinner liquid mixture 81 withinreusable liquid reservoir 44. As such, red ink held by temporaryliquid reservoir 54B can be deposited in a receiving region ofcliché plate 20B and any excess of the red ink in the receiving region can be scraped fromcliché plate 20B bydoctor ring 60. - Upon a conclusion of a printing use of the red ink deposited in the receiving region of
cliché plate 20B, another batch of the red ink/thinner liquid mixture 81 can be held by temporaryliquid reservoir 54B withinreusable liquid reservoir 44 for purposes of depositing more red ink in the receiving region ofcliché plate 20B to thereby use the new batch of red ink in another printing process. Alternatively, redliquid supply assembly 30B can be disassembled with a removal of disposable cup insert 50B from reusableliquid reservoir 44, and another liquid supply assembly can be assembled withreusable cup 40 as taught herein. - In the disclosure, the words "a" or "an" are to be taken to include both the singular and the plural. Conversely, any reference to plural items shall, where appropriate, include the singular.
