Abstract A linear transfer device for wafery works comprising: a work supporting means provided each in a work supplying station, one or more working stations and a work discharging station, which supports the works in erect positions in front thereof, the stations being linearly arranged with equal distances; a feeding means for axially feeding the work supporting means; a transfer bar capable of moving horizontally and vertically and holding means provided on the transfer bar which are adapted to face to the stations and have a pair of supporting grooves in order to support the work in an erect position, characterized in that the delivery or reception of the work supported by each work supporting means or each holding means can be made only by the vertical movement of the transfer bar relatively to each station and that the work supporting means can locate at the retreated positions in order to prevent from interfering with the holding means when the transfer bar is in movement.
A linear transfer device for wafery works comprising: a work supporting means disposed at each of a work supplying station, one or more working stations and a work discharging station, for supporting the works in erect positions in front thereof, the stations being linearly arranged at equal distances; a feeding means for axially feeding the work supporting means; a transfer bar mounted for moving horizontally and vertically; and a plurality of holding means provided on the transfer bar for movement therewith and each having a pair of supporting grooves in order to support the work in an erect position, characterized in that the delivery or reception of the work supported by each work supporting means or each holding means can be made only by the vertical movement of the transfer bar relatively to each station and that the work supporting means can locate at the retreated positions in order to prevent the same from interferring with the holding means when the transfer bar is in movement.
