<p>PURPOSE:To facilitate the installation of a linear motor in a carrier route by providing each one air duct on both corners of the upper part of an aluminium alloy carrier route of rectangular cross section, by providing a storing space of a linear motor stator in the center part thereof, and by covering the upper part of the stator with a fixed non magnetic material, with the aluminium alloy notched. CONSTITUTION:Compressed clean air is supplied to an air duct 12, and is blown to the upper part as well as both sides of a carrier route through nozzles 13, 14 provided in the longitudinal direction of the carrier route 10, on the upper part as well as the side surface of the air duct. A space part 15 is provided in the carrier route, and a stator 2 of a linear motor is arranged thereon. The part where the linear motor stator 2 is not arranged, remains as it is, and the weight of the carrier route is thus reduced. The upper frame part of a mold 11 correspondent to the linear motor stator 2 is notched into a predetermined size, and will not affect the operation of a needle that is to be provided on a carrier truck 1, and while the notched part is provided with a cover 16 of stainless or of non-magnetic material such as synthetic resin, so as to retain airtightness.</p> |
