Abstract

PURPOSE:To facilitate the manufacture of a sector unit by a method wherein silicon steel plates having different length are provided on both sides of a belt conveyor in the moving direction of the conveyor in accordance with the prescribed order to lamination, the steel plates located on both sides of the belt conveyor are picked up and laminated while the conveyor is at a standstill, and this cycle is repeated. CONSTITUTION:When a reactor core is formed by lamination, the core is constituted by a plurality of groups of sector form units 1. For the purpose of accomplishing said constitution, the steel plates which are formed into the unit 1 are formed in different lengths, the shortest steel plate (g) is positioned at the end part, and the longer steel plates (h), (i), (j), (k) and (l) are stacked successively thereon. Also, the steel plates are stacked facing to the above-mentioned steel plates in the order of length starting from the shortest, namely, (f), (e), (d), (c), (b) and (a), and they are formed in one body. A plurality of steel plates are divided into groups and placed on the L-type leg stands 12 and 12, located on both sides of a belt conveyor 11 opposing each other, following the above-mentioned stacking order, the guide stick 14 astriding the leg stand 12 is moved, and the steel plates are picked up by an attracting pad through the shifting frame 15 located below the guide stick 14, and they are stacked.

Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a block core for constructing a reactor core leg with a gap, and in particular, to form the block core, silicon steel plates of different lengths are used. The object of the present invention is to provide a method and an apparatus for laminating a plurality of sheets to form a double layer.

[Technical background and problems of the invention]

Conventionally, silicon steel plates a, b, e, d of different lengths are used as core legs of a reactor as shown in Fig. 2.3.
As shown in Fig. 4, a plurality of fan-shaped ennits (1), which are stacked in a fan shape with their outer edges aligned, are arranged radially in a ring-shaped jig (2) to form an annular block iron core ( 8) Assemble. Before this block iron core (8) was removed from the jig (2), resin or resin was poured between the layers of the block iron core (8), and this was solidified and integrated.

Thereafter, as shown in FIG. 1, a plurality of the block cores (8) are stacked with gap materials (4), which are insulators, in between to form a cylindrical core leg (5), and a flat plate is placed above and below the core leg (5). The reactor core (
8) is a coil.

In addition, in Fig. 4, the support stand (2a) and the support rod (2b) are connected to the fan-shaped two knits (2) in the jig (2) when assembling the block core (8).
