Abstract

A laminating device includes: a plurality of laminating heads that each holds a unit laminated body; a drum section in which the plurality of laminating heads are arranged, which holds each laminating head swingably via a support shaft, and which rotates to advance each laminating head to a laminating position facing a lamination stage; a cam section which is in contact with each laminating head and which causes each laminating head to swing around the support shaft in association with a movement of each laminating head caused by a rotation of the drum section; and a biasing member that biases each laminating head in a radial direction of the drum section.

First claim

The invention claimed is:

1. A laminating device adapted to discharge a unit laminated body in which a separator and an electrode plate are laminated onto a lamination stage and to laminate a plurality of unit laminated bodies, comprising:
a plurality of laminating heads that each holds one of the plurality of unit laminated bodies;
a drum section in which the plurality of laminating heads are arranged, which holds each laminating head swingably via a support shaft, and which rotates to advance each laminating head to a laminating position facing the lamination stage;
a cam section which is in contact with each laminating head and which causes each laminating head to swing around the support shaft in association with a movement of each laminating head caused by a rotation of the drum section; and
a biasing member that biases each laminating head in a radial direction of the drum section.

2. The laminating device according to claim 1 , wherein
the cam section does not follow the rotation of the drum section and includes a cam groove that extends in a circumferential direction of the drum section,
each laminating head includes a projecting section engaged with the cam groove, and each laminating head swings around the support shaft as the projecting section moves along the cam groove according to the rotation of the drum section, and
the biasing member presses the projecting section against a side surface of the cam groove.

3. The laminating device according to claim 1 , further comprising:
a first attraction section provided in each laminating head; and
a second attraction section provided at a position in the drum section aligned with, when each laminating head is at the laminating position, the first attraction section of each laminating head, wherein
the first attraction section of each laminating head at the laminating position and the second attraction section corresponding to the first attraction section attract each other.

4. The laminating device according to claim 1 , further comprising:
a first repulsion section provided in each laminating head; and
a second repulsion section provided at a position in the drum section displaced, when each laminating head is at the laminating position, from the first repulsion section of each laminating head, wherein
the first repulsion section of each laminating head at the laminating position and the second repulsion section corresponding to the first repulsion section are repulsive to each other.

5. The laminating device according to claim 1 , further comprising:
a first attraction section provided in each laminating head; and
a second attraction section provided in the lamination stage, wherein
the first attraction section of each laminating head at the laminating position and the second attraction section attract each other.

6. The laminating device according to claim 5 , wherein
the first attraction section is a magnet, an electromagnet, or a ferromagnetic body,
the second attraction section is an electromagnet, and
a magnetic force of the second attraction section is lowered as each laminating head leaves the laminating position.
