A grab picks up a hollow workpiece and displaces it to a machining station where, while the workpiece is held in the grab, a tool is engaged from outside with a first surface of the workpiece to finish the first surface. Then the workpiece is reoriented by the grab and engaged by a tool with a second surface of the workpiece to finish the second surface. Another tool is fitted through a large-diameter hole of the workpiece and positioned inside the workpiece adjacent a small-diameter hole and a drive spindle is coupled through the small-diameter hole to the other tool to machine an inner surface of the workpiece adjacent the small-diameter hole. These steps are then repeated to finish another interior surface of the workpiece adjacent another small-diameter hole. Finally the workpiece is displaced from the machining station and released from the grab.

A system and method for machining an elongate workpiece in a plurality of work cells are provided. The work cells are positioned along a substantially linear process flow path so that the work operations can be performed on different lengthwise portions of the workpiece simultaneously. A transport system advances the workpiece from an infeed system along the process flow path, thereby moving the lengthwise portions of the workpiece successively through the work cells. The transport system includes a plurality of pallets that can be engaged to the workpiece so that the workpiece is supported by the pallets throughout at least part of the machining system.

An apparatus for performing a variety of fast and slow operations including mounting operations upon workpieces affixed to workpiece carriers in which the slow operations are carried out at one station and the fast operations are carried out at another. The linear transfer device of the fast station operates at a stroke rate which is greater by a whole number than the stroke rate at the slow operation station, the workpiece carriers are fed in groups equal to this whole number to the slow operation units simultaneously and the slow operation units perform the same slow operation at each of a number of these units equal to that whole number.

A polishing apparatus for polishing a workpiece such as a semiconductor wafer includes a polishing section for polishing a surface of the workpiece held by the top ring, and a cleaning section for cleaning the workpiece which has been polished in the polishing section. The polishing apparatus further includes a workpiece transfer robot for transferring the workpiece to be polished to the polishing section or the workpiece which has been polished in the cleaning section. The workpiece transfer robot has a robot body, at least one arm operatively coupled to the robot body by at least one joint, a holder mechanism mounted on the: arm for holding a workpiece, and a sealing mechanism provided at the joint for preventing liquid from entering an interior of the joint.

The invention relates to a flexible manufacturing system for the automatic processing of workpieces with a random number of subsequent processing stations, whereby fast adjustment to different workpieces is ensured. The workpieces are transported to the individual processing stations by a conveyor, where they are then processed by means of freely positionable processing tools.

An improved method and machine are described for performing a plurality of working operations, such as for producing finished, wound coils, the working operations including a basic working operation requiring a relatively long time, e.g. winding the coil, and a plurality of complementary working operations each requiring a relatively short time, e.g. finishing the wound coil, the improvement being in carrying out the basic working operation on n parts simultaneously at n working stations, n being at least two, and carrying out the complementary working operations in succession on single work pieces, the work pieces being advanced at the end of each basic operation by n steps of which the last step is followed by a long stop, for carrying out the next basic working operation and a complementary working operation, and the other steps are followed by short stops for carrying out only complementary working operations.
摘要:
Apparatus for handling and conveying a plurality or succession of articles, such as workpiece holders or carrier blocks, from a loading station where the articles, workpiece holders or carrier blocks are manually loaded onto an intermittently moved conveyor and thence are moved from the loading station to and through a plurality of work stations and finally moved to a manual unloading station. The workpiece holders or carrier blocks may, for example, be so-called optical lens blank spot blocks each of which holds or supports a plurality of optical lens blanks which are workpieces that are to be ground to a desired shape and then polished. Under these conditions the plurality of work stations include in succession a rough grinding station, a fine grinding station, and first, second and third polishing stations. The intermittently moved conveyor extends past all of the stations and through an endless looped path of travel. The conveyor comprises a succession of evenly spaced-apart workpiece holder conveyor plates for conveying the workpiece carrier blocks or holders to and from the work stations. A rotatable workpiece holder support means or turntable is provided at each work station and, since it requires approximately three times as long to polish lens blanks as it does to rough grind or to fine grind the blanks, the workpiece holder support means or turntables at the grinding stations are intermittently moved through rotational or arcuate paths of motion or travel three times as often as the similar turntables at the polishing stations. Each of the succession of carrier blocks or workpiece holders are manually loaded in a recess in every other successive one of the conveyor plates of the conveyor and each workpiece holder or carrier block is transferred by such conveyor to and from the support means or turntables at the grinding stations for grinding operations of lens supported on the carrier blocks or workpiece holders. Every first, second and third carrier block or workpiece holder is transferred to and from the support means or turntables at the first, second and third polishing stations, respectively. The conveyor is intermittently moved through its looped path of travel in time relationships with the intermittent movement of the turntables or support means at the plurality of work stations. Automatic control means are provided for the grinding and polishing operations.
摘要:
An apparatus for and method of transferring articles, such as cylindrical cans, from a plurality of can forming devices to a high speed can trimming machine whereby cans are transferred in a positive and efficient manner and shutdown of one or more of the plurality of can forming devices will not require stopping of the can trimming machine.
摘要:
A conveying apparatus conveys an article between a wait position and a processing position. The conveying apparatus includes a plurality of arms that sandwiches the article between leading ends of the arms located on opposite sides of the article and that is provided to enable base ends of the arms to turn so as to move the leading ends in an up-down direction, and a control apparatus that turns the arms to lift the article located at one of the wait position and the processing position and sandwiched between the arms and that moves the arms with the article kept lifted thereby to the other of the wait position and the processing position, the control apparatus turning the arms to lower and mount the article at the other of the wait position and the processing position.
摘要:
A manufacturing system including a base and multiple work machine modules that are arranged in an arrangement direction on base to be attachable to and detachable from base, in which one wheel of a pair provided on work machine module is engaged with one rail of a pair provided on base in a state in which positional deviation in the arrangement direction is prohibited, and the other wheel of the pair is engaged with the other rail of the pair in a state in which positional deviation is permitted in the arrangement direction, thereby the position of work machine modules on the base in the arrangement direction is specified, and work machine modules are fixed at a setting position on the base to be restricted so as to be drawn toward the base by a module fixing mechanism that is provided on the base.
