TRANSFER APPARATUS

1 . A transfer apparatus comprising:

an arm including a rotation fulcrum portion; and

a grip mechanism connected to the rotation fulcrum portion and turnable around the rotation fulcrum portion,

wherein

the grip mechanism includes a first grip portion which grips a first surface of a grip target object, and a second grip portion which grips a second surface crossing the first surface of the grip target object,

the first grip portion includes a first pad including a first grip surface which grips the first surface, and a first support member which supports the first pad, and

the second grip portion includes a second pad including a second grip surface which grips the second surface, and a second support member which supports the second pad, moves the second pad in a direction crossing the second grip surface, and is connected to the rotation fulcrum portion together with the first support member.

2 . The transfer apparatus of claim 1 , further comprising:

a hold mechanism which holds the grip mechanism in a standby position and turns the grip mechanism; and

a movement mechanism which supports the arm and moves the grip mechanism together with the arm,

wherein

when the grip target object gripped by the grip mechanism is lifted and moved by the movement mechanism and the arm, the hold mechanism holds the grip mechanism in the standby position.

3 . The transfer apparatus of claim 1 , further comprising:

a hold mechanism which holds the grip mechanism in a standby position and turns the grip mechanism; and

a movement mechanism which supports the arm and moves the grip mechanism together with the arm,

wherein

the grip mechanism is supported on the rotation fulcrum portion such that the grip mechanism is turnable between the standby position and an inclined position which is inclined with respect to the standby position, and

when the grip target object gripped by the grip mechanism is lifted and moved by the movement mechanism and the arm, the hold mechanism turns the grip mechanism from the standby position to the inclined position, and maintains the grip target object in a state of being tilted with respect to a mounting surface.

4 . The transfer apparatus of claim 3 , further comprising a control unit which executes first drive and second drive of the hold mechanism,

wherein

the hold mechanism maintains a relative positional relationship between the arm and the grip mechanism by the first drive, and the hold mechanism turns the grip mechanism by the second drive, and

when the grip target object is lifted and moved,

the control unit drives the hold mechanism by the second drive and tilts the grip target object with respect to the mounting surface, and subsequently, the control unit drives the hold mechanism by the first drive and maintains the grip target object in the state of being tilted with respect to the mounting surface.

5 . The transfer apparatus of claim 1 , further comprising:

a hold mechanism which exerts an attractive force on the grip mechanism; and

a movement mechanism which supports the arm and moves the grip mechanism together with the arm,

wherein

the grip mechanism is supported on the rotation fulcrum portion such that the grip mechanism is turnable between the standby position and an inclined position which is inclined with respect to the standby position,

in a state where the grip mechanism does not grip the grip target object, the hold mechanism holds the grip mechanism in the standby position, and

when the grip target object gripped by the grip mechanism is lifted and moved by the movement mechanism and the arm, the grip mechanism turns from the standby position to the inclined position, and the grip mechanism and the hold mechanism maintain the grip target object in a state of being tilted with respect to a mounting surface.
