A linear conveyor device is installed on a platform having an upper surface which serves as a predetermined installation surface. The linear conveyor device includes a linear motor stator; a slider which includes a linear motor mover; a straight-line conveyance part formed by linearly connecting a plurality of modules to each other, the modules each including a base frame that has an upper surface having guide rails for guiding the movement of the slider and a lower surface facing the platform; and a base member disposed between the upper surface of the platform and the lower surfaces of the modules at a connecting portion between the modules, and configured to position and support the pair of modules to be connected to each other.

Linear conveyor device

The linear conveyor device includes a position detecting device including a scale attached to a slider, and a sensor structural body including a sensor and a driver. The driver is provided with a first and a second signal processing units, and a signal comparison processing unit. The first signal processing unit performs predetermined first interpolation processing on an output signal from a first sensor, generates and outputs first positional data. The second signal processing unit performs predetermined second interpolation processing on an output signal from a second sensor, generates second positional data, and outputs the second positional data. The signal comparison processing unit recognizes the first positional data as positional information of the slider, generates identification information unique to the slider, and outputs the identification information, where the identification information corresponds to a difference between the first positional data and the second positional data.

A linear conveyor device includes a slider having a linear motor mover; a straight-line conveyance part formed of a connected body of modules each having a linear motor stator and first and second guide rails for guiding movement of the slider on an upper surface of the module; and a cover member. The cover member covers the upper surface of the module so as to cover and conceal the linear motor stator and the first and second guide rails from above. The slider has a shape which allows the slider to be fitted on the cover member in a movable manner in an extending direction of the straight-line conveyance part.

A linear conveyer includes a stationary module and a slider. The stationary module includes a frame extending linearly, a stator including armature coils and fixed to the frame, a rail, and a magnetic sensor. The slider movable along the rail with a driving linear motor includes magnetic poles, a rail guide fitted on the rail, and a magnetic scale. The magnetic scale includes a plastic magnet having magnetic poles and extending along an extending direction in which the rail extends, and a back yoke where the plastic magnet is placed. A position of the slider is detected by the magnetic sensor and the magnetic scale. The plastic magnet has a fixed portion that is fixed with respect to the back yoke and a portion other than the fixed portion, the portion being movable relative to the back yoke along an extending direction in which the magnetic scale extends.
