A spiral parts heat treatment apparatus includes a first guide, a transfer unit, a second guide, and a controller. The first guide has a carrier portion that continuously conveys the manufactured spiral parts carried thereon in a longitudinal direction. The transfer unit is disposed downstream from the first guide to feed the spiral parts one by one after discrimination. The second guide is provided continuously to the transfer unit and has a carrier portion and a driving portion. The carrier portion serves to guide the spiral parts carried thereon in the longitudinal direction in the heat treatment furnace. The driving portion serves to push the spiral parts from a rear end side thereof and a driving portion. The controller performs a control operation so as to feed the spiral parts one by one.

Spiral parts heat treatment apparatus and method, and spiral part

This invention has as its object to provide an ink-jet head assembling apparatus, which can improve productivity by omitting the step of temporarily fixing a top plate and a heater board using an ultraviolet curing adhesive. In order to achieve this object, an ink-jet head assembling apparatus of this invention includes a plurality of work stations, an index table, upper and front pressing members, arranged at a position on the index table corresponding to at least one of the plurality of work stations, for holding the top plate on the heater board, and first and second driving mechanisms, arranged outside the index table, for switching the holding member between a holding state wherein the top plate member is held on the heater board, and a non-holding state attained by releasing the holding state.

Assembling method and apparatus for ink-jet head

Disclosed in an ink-jet head assembling method for executing alignments between a top plate and a heater board. The method comprises steps of holding the top plate by fingers, moving the fingers to bring the top plate to a position above the heater board with adhesives having been applied, releasing the holding of the fingers, enabling them to engage with an ink reception port of the top plate, and moving the fingers sideways to abut against the ink reception port, and adjusting a relative position between heaters of the heater board and nozzles of the top plate.

Ink-jet head assembling method

An ink-jet head assembling apparatus assembles a nozzle head of an ink-jet head for discharging an ink in a predetermined pattern from a heater board having a plurality of heaters for heating the ink, and a top plate member having a plurality of discharge orifices for discharging the ink heated by the corresponding heaters in a jet-like manner. The apparatus is provided with a first position detection mechanism for measuring forming positions of the discharge orifices of said top plate member, a second position detection mechanism for detecting arranging positions of the heaters on said heater board, a position adjustment mechanism for comparing a first detection result detected by said first position detection mechanism with a second detection result detected by said second position detection mechanism, and moving said top plate member relative to said heater board by a shift amount between the two detection results so as to align the positions of the heaters with the positions of the corresponding discharge orfices, and an adhesion mechanism for adhering said top plate member and said heater board aligned by said position adjustment mechanism to each other.

Ink-jet head assembling apparatus and method

An apparatus for isolating a plurality of parts is operable, with, e.g., an image recognizing apparatus which records the position and configuration of the parts, and a conveying and placing apparatus used to align the parts on a part alignment section. The part isolating apparatus includes an isolation table having a centrally located bore defined by a surface sloping downwardly toward the center of the table, and a frame member for supporting the table. A bag member is mounted around the lower edge of the table for receiving a plurality of parts and includes an isolation frame for holding a part to be isolated. A thrusting head vertically lifts the bottom of the bag member. When the thrusting head ascends through the bore, one of the parts becomes isolated from the others. Another form of the part isolating apparatus comprises a bag member receiving a plurality of parts, a frame for supporting the bag member, and an isolation frame mounted on a lower inner surface of the bag member for supporting an isolated part. An ascending device raises and lowers the isolation frame from a position wherein the bag member is suspended to a position wherein the bag member is inverted. The part isolated from the others is supported by the isolation frame at its ascended position. The apparatus is capable of isolating parts and aligning their attitude, regardless of the varying type or shape of the parts.
