Abstract

PURPOSE:To decide a stop position with high accuracy without deteriorating the fast and quiet movement and the non-maintenance properties of a carrier device, by using a movable iron core attached to a body moving along a carriage route, a control member set on the carriage route and an attracting force generating means for movable iron core. CONSTITUTION:A pallet 10 is detected the access to a station based on the detection signal of the 1st sensor set at the front of the station. Thus a stopper 12 moves up to its upper end position and is set in an active mode. When the front end face of the pallet 10 has a contact with the stopper 12, the 2nd sensor set at the position of the 2nd sensor works to supply a current to an energizing coil 22 of an electromagnet 23. Then a movable iron core 20 attached to the pallet 10 is attracted by the magnet 23 and energized forward. Thus a moving body can be set at a prescribed stop position of the station with high accuracy in a state where the front end face of the pallet 10 is pressed to the stopper 12.

“Prior Art” Traditionally, single-sided linear induction motors (hereinafter referred to as LI
A transport device using a drive source (abbreviated as M) as a drive source is known. As shown in FIGS. 2(a) and 2(b), this conveying device includes a free roller conveyor 4.4 installed along the conveying path and having rollers 2, 2, etc. The LrM stator (hereinafter referred to as the stator) 6, which is responsible for generating a traveling magnetic field, and the rollers 2, 2, etc. are supported so as to be movable along the conveyance path, and the lower surface has a secondary LRM movable element. It is purchased from a pallet 10 to which a side conductor 8 is attached. Then, by sequentially exciting the plurality of stators 6 in positive phase to apply thrust in the forward direction to the pallet 10, the pallet 10 moves in the forward direction while being accelerated every time it passes above the stator 6. In addition, when decelerating or stopping the pallet 10 in motion, the stator 6
