Abstract:
A method and apparatus for automated loading and unloading of a cylinder (114) in an engraver (110) which permit the engraver (110) to accommodate cylinders (114) of differing geometries, including a range of lengths, diameters, and mounting configurations. The engraver (110) includes a headstock (116) and tailstock (118) which rotatably support a cylinder (114) at an engraving station (115) in the engraver (110), and a cylinder handling system having at least one cylinder (114) and support (130) for supporting the cylinder between the headstock (116) and tailstock (118) during loading and unloading of the cylinder (114). In one form, the cylinder supports (130) each have a telescoping support member having a support nest for engaging and supporting the cylinder (114) at the engraving station (115). In another form, the cylinder supports (130) each have a support housing and support structure mounted to the support housing, the support structure including at least one cylinder receiving area, selection being possible between plural cylinder receiving areas for receiving cylinders (114) of different dimensions.

Abstract:
An image scanning device includes a housing, a scanning carriage (21), and a first guide groove (53) and a second guide groove (57). The housing includes a bottom chassis and a side wall member (14a), and configures a document tray. The scanning carriage is movably arranged in the housing. The first guide groove and the second guide groove are arranged at the side wall members of the housing, and guide the scanning carriage in a scanning direction (X).
Abstract:
A lathe bed scanning apparatus and method has a wear resistant coating on translational rod bearings which support a scanner for slidable movement in a frame. Titanium nitride is coated over a hardened stainless steel core of the translational rods and bearing pads which are arranged for sliding contact with the rods comprise diamond laminated tungsten carbide.
Abstract:
An automatic self-centering chuck system for use on an engraver. The chuck system includes a plurality of jaws which are slidably mounted for movement in a radial direction toward a central aperture of the chuck to clamp a shaft for an engraving cylinder. Each of the jaws (102) is actuated for movement by a lever (132) pivotally mounted within the chuck. The levers (132) are actuated for pivotal movement by an axially reciprocating drawbar (64) which is energized for movement by a series of pneumatic cylinders. The components of the chuck are accurately machined to provide close tolerance, precise movements of the jaws (102) whereby a cylinder (24) will be accurately positioned at the central rotational axis of the chuck. In order to ensure that the precise level of jaw movement is maintained throughout the life of the chuck, a lubricant flushing or purging system is provided for flushing normal wear particles from the precision components internal to the chuck.
Abstract:
An image reading device comprising: a document placing portion; a conveyor; a reading unit configured to read an image of the document, wherein the reading unit includes: an image sensor; a support which supports the image sensor, wherein in the case of reading the image of the document conveyed by the conveyor, the support is to be stopped at a predetermined reading position; a guide; and a driving unit, wherein the reading unit further includes: a release unit configured to release the contact with the guide by separating the support from the guide when the support is moved toward the predetermined reading position; and a contact portion configured to contact with the support separated from the guide by the release unit when the support is moved toward the predetermined reading position.
Abstract:
Die Erfindung betrifft eine Antriebsvorrichtung (1) für eine optische Abtasteinrichtung (5) mit einer Gewindespindel (16), auf der eine Spindelmutter (23) aufgefädelt ist. Die Antriebsvorrichtung (1) enthält ferner ein Kopplungsmittel (24) zum Ankoppeln der Spindelmutter (23) an die Abtasteinrichtung (5). Dabei gewährleistet das Kopplungsmittel (24) eine kardanische Kopplung nach Art eines Kardangelenks. Erfindungsgemäß kann auf technisch einfache Weise ein besonders guter Gleichlauf beim Abtasten gewährleistet werden.
Abstract:
A method and apparatus for automated loading and unloading of a cylinder (14) in an engraver (10). The method and apparatus permit the engraver (10) to accommodate cylinders (14) of differing geometries, including a range of lengths, diameters and mounting configurations. The engraver (10) comprises a headstock (16) and a tailstock (18) which cooperate to rotatably support a cylinder (14) at an engraving station (15) in the engraver (10). The engraver (10) also comprises a cylinder handling system having at least one cylinder support (30) for supporting the cylinder (14) between the headstock (16) and tailstock (18) during loading and unloading of the cylinder (14). The cylinder handling system comprises a driver (32) for driving the cylinder support (30) towards and away from the engraving station until the headstock (16) and tailstock (18) engage and rotatably support the cylinder (14). Once the cylinder (14) is rotatably supported between the headstock (16) and tailstock (18), then the cylinder support (30) is retracted. Each cylinder support (30) comprises a telescoping support member (34) having a support nest (36) for engaging and supporting the cylinder (14) at the engraving station (15).
