  • Conveyor and conveying method
    Patent number: 9415942
    Abstract: A conveyor is provided with a supply roll, a detection device and a brake force applying device. The supply roll is rotatably arranged and is configured to support a belt-shaped cell material for an electrode or a separator to intermittently feeding out the cell material by rotation of the supply roll. The detection device is arranged with respect to the supply roll to detect an amount of the cell material remaining on the supply roll. The brake force applying device operatively coupled to the supply roll to apply brake force to the rotation of the supply roll based on the amount of the cell material detected by the detection device.

  • Work transport apparatus and method
    Patent number: 8424669
    Abstract: A work transport apparatus includes a carriage to carry a work along a guide lane; a work loading mechanism to load the work on the carriage at a work loading position; and a work unloading mechanism to unload the work from the carriage at a work unloading position. Each of the work loading mechanism, the carriage and the work unloading mechanism includes a work sliding incline sloping down to move the work held on a holder from the work loading mechanism through the carriage to the work unloading mechanism. Each of the work unloading mechanism, the carriage and the work loading mechanism includes a holder sliding incline sloping down to move the holder from the work unloading mechanism through the carriage to the work loading mechanism.
