Abstract: Provided is a plate-like material feeding device configured to sandwich a plate-like material between a lower roll rotatably supported on a device main body and an upper roll which is rotatable and arranged to face the lower roll in parallel thereto, so as to convey the plate-like material. The plate-like material feeding device includes: a lower gear integrally provided on a rotation shaft of the lower roll; an intermediate gear which is meshed with the lower gear, and is integrally provided on a rotation shaft of the upper roll; an upper gear meshed with the intermediate gear; a lower-roll drive motor which is coupled to the rotation shaft of the lower roll so as to drive the rotation shaft of the lower roll to rotate; and an upper-roll drive motor configured to drive the upper gear to rotate.

Abstract: A breakage prevention mechanism is configured to prevent deformation or breakage of a crossbar and transfer the work even in the condition where a pair of left and right arm supporting the both end of the cross bar is displaced beyond assumption. The breakage prevention mechanism is equipped with a pair of arms which is synchronized and moves approximately parallel, and a crossbar bridged between the top end of the arms. Both end of the crossbar and the arm are connected pivotably around two axis. Both end of the crossbar are configured to be slidable against the arm in X axis direction. The plunger is placed between both end of the crossbar and arm, in which protects the crossbar by restraining the pivoting and the sliding of both in the normal condition and releasing the restraint when the unintended force is given.

Abstract: A transferring apparatus is composed of a first arm swingably provided around a first axis of a pedestal, a second arm whose length is different to the first arm is swingably provided around a second axis, a hand attached to the front end of the second arm, and a first motor to reciprocatingly swings the first arm provided in the pedestal. A first pinion is fixed to the pedestal concentrically to the first shaft, and a second pinion is fixed to the base end of the second arm concentrically with the second axis. Further, racks are provided in the both of left and right side of the first pinion and the second pinion. A large transferring apparatus is composed so that two transferring apparatus are arranged in one pair, the hand are mutually coupled by a transfer beam.
