Definitions
- the energy director element is of the same material as the remainder of the plastic component and is formed in the mold in which the plastic component is created. During the ultrasonic welding process it is the energy director element which is first melted primarily as a result of the friction created between the two surfaces to be
- a further object of the present invention is to provide an improved method of rejoining subassemblies of previously depleted toner cartridges which permits the toner cartridge to be separated again at the location of the rejoining.
- Figure 1 B is a perspective view of a prior art fastening clip.
- Figure 4A is a perspective view of an apparatus used in the ultrasonic welding step via point welding of the present invention.
- Figure 4B is a stylized perspective view of an apparatus which may be used in the ultrasonic welding step via line welding of the present invention.
- FIG. 6B is a cross-sectional view through a portion of the Figure 6A assembly of a representative process cartridge of the present invention at the location of an ultrasonic weld stylized to represent conformational change due to melting and pressure from the welding horn in the ultrasonic welding step.
- the remanufactured toner cartridge of the present invention (20) includes first peripheral lip (32) and second peripheral lip (34) of plastic roller section (22), and first peripheral lip (36) and second peripheral lip (38)(not shown) of plastic hopper section (24).
- Sealing blade (26) is disposed adjacent the developer roller (80) which is rotatably attached to roller supports (28) and (30) in roller section (22).
- Sealing blade (26) is conventionally fabricated of mylar sheet material having a thickness generally of the order of about 0.004 inch (0.01016 cm). It is highly preferred that the sealing blade (26) be essentially straight and uniformly positioned with respect to the surface of the developer roller (80) along its length. Variations in the degree of straightness or uniformity of positioning of sealing blade (26) with respect to the surface
- Figure 2B is depicts a toner cartridge in the present invention that is substantially similar to the one shown in Figure 2A.
- toner (20) includes longitudinal channel (31 ) having floor (29)(not shown).
- toner (20) includes components such as first peripheral lip (32) and second peripheral lip (34) of plastic roller section (22), and first peripheral lip (36) and second peripheral lip (38)(not shown) of plastic hopper section (24).
- Sealing blade (26) is disposed adjacent the developer roller (80) which is rotatably attached to roller supports (28) and (30) in roller section (22).
- Sealing surface (43) of cavity (42) is adapted to accept and mates with adhesive surface (51) of toner port ribbon seal (46) and adhesive surface (52) of toner port perimeter seal (48), to close and seal toner port (44).
- Toner port ribbon seal (46) and toner port perimeter seal (48) are commercially available as an integral unit from OF. Technology (Goldseal).
- Perimeter seal (48) covers a larger area than does ribbon seal (46) and thus maintains a seal against toner leakage upon removal of the ribbon seal by the end user.
- hopper section (24) includes toner fill port (53) closed by hopper cap (50).
- Figure 3B is a partially disassembled perspective view of the hopper section (24), with the hopper section toner port perimeter seal (48), toner port ribbon seal (46) and roller section (22) assemblies of the toner cartridge (20) depicted in Figure 2B.
- the components of the toner shown in Figure 3B are substantially the same as depicted in Figure 3A, except the lips (37) and (39) are shown with longitudinal channels.
- Figure 9 is a partially disassembled perspective view of an embodiment of the present invention in which a toner port perimeter seal (48) is not needed, as the line welding technique employed is sufficient to act a seal.
- Toner port ribbon seal (46) is commercially available as a separate item.
- ultrasonic welding of sections (22) and (24) together is accomplished by a multi-head ultrasonic welding apparatus (70) such as is available from Branson Ultrasonics Corporation, Danbury, Connecticut. It is preferred
- the present invention also provides another ultrasonic welding method, namely line welding, as described with reference to Figure 4B.
- Ultrasonic welding of sections (22) and (24) together is accomplished by a dual-head ultrasonic welding horn (92) and ultrasonic welding apparatus (90) such as is available from Branson Ultrasonics Corporation, Danbury, Connecticut. It is provided that ultrasonic welding (and resealing) of the mating surfaces 33, 37 and 35, 39 of the cartridge sections take place simultaneously. However, it will be understood by one of ordinary skill in the art that the welding may take place sequentially.
- an ultrasonic weld (40) is schematically depicted in cross-section to represent conformational change due to melting of the two cartridge sections (22) and (24) and pressure from titanium ultrasonic welding horns (92) which are depicted in partial cross-section.
- welding horns (92) bear on channel floor (29) of longitudinal channel (31) to apply ultrasonic energy to the interface between mating surfaces (33) and (37) of section (22) and section (24), respectively.
- welding horns (92) bear on second peripheral lip (34) of roller section (22) to apply ultrasonic energy to the interface between mating surfaces (35) and (39) of section (22) and section (24), respectively.
- reassembled toner cartridge (20) is maintained in preferred alignment and configuration by ultrasonic welds (40) such that longitudinal axis (84) of developer roller (80) and sealing blade axis (82) are essentially parallel along the extent or length of sealing blade (26), and the proximate surfaces of sealing blade (26) and roller (80) are maintained in substantially constant relation to each other over their mutual extent.
- the depleted toner cartridge (20) is visually inspected for damage and whether it is suitable to be remanufactured. It is then partially disassembled to remove external components including the waste hopper, gear housing end plates, rollers, and hopper cap, etc. Next, any residual toner is removed and the cartridge is cleaned.
- roller section (22) is then separated from the hopper section (24) along the plane of the ultrasonic weld joining the two sections by a rotating blade which cleaves the ultrasonic weld. Thereafter the components are inspected for cleanliness and
- the roller section (22) is then mated with the recharged hopper section (24) and the loose assembly is placed into a clamp jig which has been constructed to properly align and configure the particular type or model of cartridge being processed.
- the clamp jig is operated to impose the preferred alignment and configuration on the cartridge assembly.
- a multi-head (ten heads being preferred) ultrasonic welding apparatus simultaneously welds the roller section (22) and the hopper section (24) together at ten predetermined locations.
- a multi-head ultrasonic welding horn connected to an ultrasonic welding apparatus simultaneously welds the roller section (22) and the hopper section (24) together along both longitudinal edges at essentially the same locations as the original ultrasonic welds. If either case, this welding process requires approximately 1 second. Pressure on the weld points is maintained by the welding apparatus for approximately 10 seconds until the bond has cured, after which the resealed cartridge (20) is removed from the jig.
- components - new or repaired as necessary (developer roller, photoconductive drum, developer blades, etc.) - are installed in the roller section.
- the waste hopper is installed and the finished reassembled toner cartridge is subjected to post production quality control testing, after which it is packaged for shipment.
