Abstract

An electrode body producing apparatus is provided with a rotary base body, stacking table portions provided on its outer peripheral end portion, and a workpiece transferring section to transfer an unplaced workpiece on an object placement surface of a post-placed laminated body and others. A height adjusting portion of the stacking table portion changes a radial height of a table surface so that a radial height of the object placement surface becomes a predetermined radial height at least at a workpiece transferring angular position, and the workpiece transferring section transfers and places the unplaced workpiece on the object placement surface in synchronization with rotation movement of the object placement surface at the workpiece transferring angular position.

First claim

What is claimed is:

1. An electrode body producing apparatus configured to produce a laminated electrode body formed by stacking a plurality of workpieces, the electrode body producing apparatus comprising:
a rotary base body of a cylindrical shape configured to rotate about a rotary axis;
a plurality of stacking table portions provided on an outer peripheral edge portion of the rotary base body to rotate and move with the rotary base body;
a workpiece transferring section configured to transfer and place an unplaced workpiece onto an object placement surface of any one of a table surface of the respective stacking table portions and a radial outer surface of a post-placed laminated body which is held by the table surface, the unplaced workpiece being an unstacked workpiece, and the post-placed laminated body including one or more workpieces that have been placed on the table surface;
a controller; and
an electrode body transferring section configured to transfer the laminated electrode body, which has been completed, from the plurality of stacking table portions,

wherein
the object placement surface is arranged parallel to a rotary direction of the rotary base body,
each of the plurality of stacking table portions comprises a height adjusting portion configured to change a radial height of the table surface,
the height adjusting portion is configured, at least at a workpiece transferring angular position on which the unplaced workpiece is transferred from the workpiece transferring section to the object placement surface, to change the radial height of the table surface such that a radial height of the object placement surface becomes a predetermined radial height,
the workpiece transferring section is configured to transfer and place the unplaced workpiece onto the object placement surface in synchronization with rotation movement of the object placement surface at the workpiece transferring angular position,
the electrode body transferring section comprises an electrode body receiving portion configured to receive the laminated electrode body which has been separated from a corresponding stacking table portion of the plurality of stacking table portions, and
the controller is configured to control the electrode body transferring section to receive and transfer the laminated electrode body at an equal speed with rotation movement of a radial outer top face of the laminated electrode body at an electrode body transferring angular position on which the laminated electrode body is transferred from the corresponding stacking table portion to the electrode body receiving portion as well as at a discharging timing of discharging the laminated electrode body.

2. The electrode body producing apparatus according to claim 1 , wherein
the workpiece transferring section is configured to stack the unplaced workpiece onto the radial outer surface of the post-placed laminated body which is held by the table surface in a direction perpendicular to the table surface while the plurality of stacking table portions is rotated and moved with the rotary base body.

3. The electrode body producing apparatus according to claim 1 , wherein
the workpiece transferring section includes a surface configured to hold the unplaced workpiece, and
the workpiece transferring section is configured to transfer and place the unplaced workpiece onto the object placement surface when the surface of the workpiece transferring section is parallel to the object placement surface.

4. The electrode body producing apparatus according to claim 2 , wherein
the workpiece transferring section includes a surface configured to hold the unplaced workpiece, and
the workpiece transferring section is configured to transfer and place the unplaced workpiece onto the object placement surface when the surface of the workpiece transferring section is parallel to the object placement surface.

5. The electrode body producing apparatus according to claim 1 , wherein
the object placement surface is parallel to the outer peripheral edge portion of the rotary base body.

6. The electrode body producing apparatus according to claim 1 , wherein
the object placement surface faces an outer side of the rotary base body in a radial direction of the rotary base body and is configured to rotate, as a flat contact surface for the unplaced workpiece or the post-placed laminated body, coaxially with the rotary base body.
