Method for conveying fuel cell separator material
Provided is a method for conveying a separator that ensures stably conveying a separator material without leaving an indentation or the like. The conveyance method conveys a separator material for use in a single cell of a fuel cell. A hydrogen gas and an air are supplied for the fuel cell to generate electricity. The separator material has a rectangular shape in a plan view of the separator material, and the separator material has both sides on which a pair of through-holes are formed at proximity of a pair of hydrogen distribution ports through which a hydrogen gas flows. The conveyance method includes, when the separator material is conveyed, inserting a conveyance pin into each of the through-holes formed on the separator material, and in a state where the conveyance pin is inserted in each of the through-holes, conveying the separator material while pulling the separator material in a direction in which the conveyance pins mutually separate.

Apparatus for conveying molded body for heat exchanger fins
Provided is a conveying apparatus for conveying a molded body for heat exchanger fins that can achieve high-speed conveyance of a molded body for heat exchanger fins, prevent generation of noise during conveyance, and have a smaller size. A solution is a conveying apparatus for conveying in a predetermined direction, a molded body for heat exchanger fins in a stage after a metal thin plate is provided with through-holes and before the metal thin plate is cut into a predetermined length in a conveying direction, the apparatus including: a rotary conveying body including a plurality of protrusions that are tapered and can enter the through-holes, and including a rotation shaft in a direction orthogonal to the conveying direction of the molded body for heat exchanger fins in a horizontal plane; and a rotary conveying body driving unit that rotates and drives the rotary conveying body, wherein a side surface shape of each of the protrusions is a shape to enable the protrusion to enter the through-hole with a space maintained in synchronization with a rotation of the rotation shaft, and retract from the through-hole while the protrusion conveys the molded body for heat exchanger fins in contact with the through-hole.
PRESS SYSTEM AND CONTROL METHOD OF PRESS SYSTEM
A press system and a control method of the press system that can automatically set a timing for coordinating a press machine and a feeding device. A leveler feeder includes feed rolls that convey a coil material to the press machine in a closed state in which the coil material is clamped, and are brought into an open state in which the coil material is released when stamping by the press machine is started. The press machine includes a sensor for detecting a load F at a time of the stamping, a pilot pin that is inserted into a hole pierced in the coil material for positioning at a time of the stamping, and a controller for controlling the leveler feeder and the press machine so as to perform the stamping in coordination with each other. The controller determines a release start timing Tos (a position Ps+L) at which the feed rolls are switched from the closed state to the open state based on a result of detecting by the sensor as well as a length L of the pilot pin.
EQUIPMENT FOR HIGH-SPEED NECK FORMING OF CANS THROUGH MULTI-CHANNEL FEEDING
A kind of equipment for high-speed neck forming of cans through multi-channel feeding includes a can entry station and multiple sets of neck forming stations; a can entry station comprises at least two sets of can entry channels and a loading transfer turntable; each set of can entry channel comprises a feeding turntable and a feeding transfer turntable; the feeding turntable corresponds to a loading channel setting, and the number of loading channels is the same as the number of can entry channels; several vacuum adsorption grooves are distributed on circumferential surface of the feeding turntable; several vacuum adsorption grooves are distributed on circumferential surface of the feeding transfer turntable; when the feeding turntable and the feeding transfer turntable rotate to feed, two corresponding vacuum adsorption grooves on both parties are jointly to form a circular junction; the can body enters the vacuum adsorption groove of feeding transfer turntable through the junction from the vacuum adsorption groove of feeding turntable; the loading transfer turntable is located at the rear of each feeding transfer turntable, and the feeding transfer turntable of each can entry channel feeds alternately to the loading transfer turntable. The present invention can greatly increase production speed or reduce the speed requirements of the original mechanism of the equipment, and ensure the stability of the can when entering the mold.
METHOD OF MANUFACTURING STACKED CORE AND APPARATUS FOR MANUFACTURING STACKED CORE
A method of manufacturing a stacked core includes forming a first pilot hole in a strip-like metal plate by a first punch, and working a predetermined portion of the metal plate by a second punch, in a state in which a first pilot pin is inserted into the first pilot hole. A worked portion of the metal plate that is worked by the second punch is press-fitted into the metal plate, in a state in which a first pilot pin is inserted into the first pilot hole, and a second pilot hole is formed in the metal plate by a third punch, after press-fitting the worked portion into the metal plate and before performing another work on the metal plate.
