1. An apparatus for manufacturing a laminated electrode body, the apparatus comprising:
a laminating unit that includes:
a rotatable cross arm having a rotation center;
a first transport head positioned at a first distance from the rotation center of the cross arm;
a second transport head facing the first transport head with the rotation center interposed therebetween and positioned at a second distance shorter than the first distance from the rotation center;
a third transport head arranged 90° around the rotation center relative to the first transport head and positioned at the first distance from the rotation center; and
a fourth transport head facing the third transport head with the rotation center interposed therebetween and positioned at the second distance from the rotation center;
a positive electrode supply stage that includes:
a first positive electrode mounting table positioned at the first distance from the rotation center of the cross arm when the positive electrode supply stage is positioned at a positive electrode supply position; and
a second positive electrode mounting table positioned at the second distance from the rotation center of the cross arm when the positive electrode supply stage is positioned at the positive electrode supply position;
a negative electrode supply stage that includes:
a first negative electrode mounting table positioned at the first distance from the rotation center of the cross arm when the negative electrode supply stage is positioned at a negative electrode supply position; and
a second negative electrode mounting table positioned at the second distance from the rotation center of the cross arm when the negative electrode supply stage is positioned at the negative electrode supply position;
a first laminating stage positioned at the first distance relative to the rotation center of the cross arm; and
a second laminating stage facing the first laminating stage with the rotation center of the cross arm interposed therebetween and positioned at the second distance relative to the rotation center of the cross arm,
wherein the laminating unit is configured such that after the first transport head picks up a first positive electrode on the first positive electrode mounting table and the second transport head picks up a second negative electrode on the second negative electrode mounting table, the cross arm rotates by 90° in a first direction, the first transport head mounts the first positive electrode on the first laminating stage, and the second transport head mounts the second negative electrode on the second laminating stage, and
the laminating unit is configured such that after the third transport head picks up a first negative electrode on the first negative electrode mounting table and the fourth transport head picks up a second positive electrode on the second positive electrode mounting table at positions where the first transport head mounts the first positive electrode on the first laminating stage and the second transport head mounts the second negative electrode on the second laminating stage, the cross arm rotates by 90° in a second direction opposite to the first direction, the third transport head mounts the first negative electrode on the first laminating stage, and the fourth transport head mounts the second positive electrode on the second laminating stage.
