摘要:
A system for loading a plurality of cylindrical members, initially oriented to longitudinally extend in a first direction, into a processing module adapted to receive the plurality of cylindrical members longitudinally extending in a second direction, is disclosed. The system is particularly adapted for use in a rotary atomization manufacturing system for manufacturing photoreceptors from the cylindrical member in the form of substrate members. The system includes a first support structure for receiving and retaining removably thereon the plurality of cylindrical members oriented to longitudinally extend in the first direction. The system transfers the plurality of cylindrical members, longitudinally extending in the first direction, to the first support structure. The system includes a second support structure for receiving and retaining removably thereon the plurality of cylindrical members oriented to longitudinally extend in the second direction. The system moves the first support structure from the first position to a second position, the first support structure in the first position orienting the plurality of cylindrical members to longitudinally extend in the first direction, the first support structure in the second position orienting the plurality of cylindrical members to longitudinally extend in the second direction, transverse to the first direction, in alignment with the second support structure. The system transfers substantially simultaneously the plurality of cylindrical members from the first support structure to the second support structure. The system transfers substantially simultaneously the plurality of cylindrical members from the second support structure to the processing module.
摘要:
A system for for removing a band of coating material from a first end of a coated cylinder having a second opposite end including ablating the band of coating material with a laser beam and directing an annular curtain of compressed fluid against the band in a direction away from the second opposite end to create an air curtain along the outer surface of the cylinder in a direction from the second opposite end toward the band and the first end.
摘要:
A process for treating a coated substrate to reduce the thickness of the coating involves directing a laser beam at a predetermined surface portion of the substrate to remove part of the coating. The process can be used to treat a coated photoreceptor to precisely reduce the thickness of the coating in a predetermined region.
摘要:
A mandrel for transporting hollow cylinders including an elongated arm having a first end and a second end, an expandable disk supported at the first end and means supported at the second end to expand the expandable disk, the mandrel arm comprising an elongated body having an imaginary axis and at least three fins extending substantially radially from the arm, each of the fins having an alignment shoulder adjacent the first end adapted to receive an end of a hollow cylinder and to coaxially align the cylinder with the elongated arm. This mandrel is used in a process for coating hollow cylinders.
摘要:
A process for forming a photosensitive imaging member comprising: (a) providing a substrate; (b) forming in successive layers on the substrate, an optional intermediate layer, and one or more photosensitive layers; and (c) rotating a conditioning wheel to roughen the exterior surface of the substrate or one of the layers prior to depositing the next successive layer thereon to provide at least one surface having a roughness sufficient to substantially suppress the formation of a pattern of light and dark interference fringes upon exposure of the photosensitive imaging member.
摘要:
A packaged belt including a single, flexible electrophotographic belt covered with a flexible protective sheet supported by at least three rollers including a hollow first roller having a longitudinal slot parallel to the axis of the first roller which imparts to the first roller a "C" shaped cross section, a lip extending from at least one long edge of the slot, a second roller parallel to and enclosed within the first roller, the second roller having an outside diameter smaller than the inside diameter of the first roller and an outside diameter larger than the maximum size of the opening between the lip and the opposite edge of the slot, a third roller adjacent to and parallel to the exterior of the first roller, the belt covered with the protective sheet having at least a partially flattened region with opposite sides of the belt adjacent each other to form a first loop at one end and a second loop at the other end, the first loop extending around the second roller and the second loop extending around the third roller, the belt extending from the second roller, through the slot, and around at least a portion of the outer periphery of the first roller and ending at the third roller. Processes for preparing the belt package and installing the belt into an electrophotographic imaging machine are also described.
摘要:
An apparatus for processing cylindrical and belt-like substrates includes: a support structure having two opposing faces and defining a central horizontal axis, each face of the support structure supporting a planetary array of substrates about the central horizontal axis to define two opposing planetary arrays of substrates, each substrate in each planetary array defining an offset horizontal axis radially spaced from and parallel to the central horizontal axis of the support structure; an array of processing modules each housing a processing chamber for receiving therein the opposing planetary arrays of substrates, each chamber defining a central horizontal axis aligned with the central horizontal axis of the support structure when the support structure is received within the chamber, and each chamber including an opening between opposing chamber sections, the opening being in a plane parallel to the central horizontal axis of the chamber; and a transport vehicle for transporting the support structure to each processing module in the array of processing modules, the transport vehicle including a reciprocating mechanism for reciprocating the support structure in a first direction perpendicular to its central horizontal axis for insertion into and withdrawal from the opening in any one of the processing chambers.
