A core manufacturing apparatus includes: a storage unit that stores core sand; a kneading vessel configured to be fed with the core sand; a kneading rod configured to knead the core sand; and a piston configured to eject the kneaded core sand. The kneading vessel is capable of transitioning between a horizontally lying state and a vertically standing state and configured to be fed with the core sand in the horizontally lying state. The piston is configured to eject the core sand downward and pack it into a mold with the kneading vessel in the vertically standing state. The storage unit includes a valve that opens and closes the feed port. The storage unit is coupled to the kneading vessel so as to be turnable around a second shaft and configured to maintain the same posture with the valve in contact with the feed port while the kneading vessel turns.

Core manufacturing apparatus

A powder supplying device () includes a case () in which a storage portion () is formed for temporarily storing powder (), the case () having an inlet () formed in an upper end of the storage portion (), and a rectangular outlet () formed in a lower end of the storage portion (); a rotor () that is arranged in the case () and transports the powder () in the storage portion () to the outlet () by rotating; and a mesh body () through which the powder () that has been transported to the outlet () passes. The powder supplying device () supplies the powder () onto an upper surface of an electrode foil (). The rotor () has a brush-like shape, with a plurality of hair members () radially implanted pointing radially outward with an axial center (G) of the rotor () as the center.

Powder supplying device and electrode manufacturing apparatus

A device for applying a working or assembling process to an article at an appropriately selected position as temporarily mounted to a supporting plate through a hole formed therein, having a housing of a generally twofold tubular structure, an annular piston disposed in an annular space in said housing and adapted to be axially reciprocated by selective supply or exhaust of pressure fluid, and a plurality of cotter members arranged in the tubular housing so as to be selectively driven out of the tubular housing radially outwardly as driven by the annular piston by way of a wedging engagement with the annular piston, so that the cotter members are driven against the inner peripheral wall surface of the hole of the supporting plate with very high force available by the wedging engagement.

Working/assembling device with self-clamping means

A highly-viscous material coating apparatus for use, e.g. in an automobile coating process, to coat a joint of a workpiece, may be mounted on a robot. It provides improved operation where the workpiece provides a reference surface parallel to the joint, where the workpiece provides a reference surface displaced from the joint at varying distances along the length of the joint, and where the workpiece provides no reference surface. Where a reference surface is available, an extendable spring-biased guide pin of the apparatus moves along the reference surface, and any positional errors are compensated-for by action of the spring. If the distance between the reference surface and the joint varies, the varying distance may be compensated for by various disclosed practices. The apparatus also can be used where no reference surface is provided by retracting the guide pin with respect to the nozzle and by controlling the robot so as to direct the nozzle to the joint. A conventional nozzle may be adapted to dispense a highly-viscous liquid without splattering or otherwise marring the surface of the workpiece by providing the nozzle with a frusto-conic recess.
