  • Patent number: 11745960
    Abstract: Whether to permit or prohibit drive of at least one object, out of a slider and a movable linear module, is determined based on position related information on position of the slider or the movable linear module before the drive of the object is started. In this way, in a linear conveyor system for transferring the slider between a plurality of fixed linear modules using the movable linear modules, the occurrence of interference between the linear modules and the slider can be suppressed.

  • Patent number: 11724894
    Abstract: A judgment process of judging whether or not the movable linear module is located in the facing range is performed before the slider transfer operation of moving the slider from the fixed linear module to the movable linear module located in the facing range is performed. As a result, unless the movable linear module is judged to be located in the facing range, the slider transfer operation is performed after a preparation operation of moving the movable linear module into the facing range is performed. Therefore, the slider can be properly moved from the fixed linear module to the movable linear module.

  • Patent number: 11702300
    Abstract: The transfer operation of moving the slider between one fixed linear module and the movable linear module while locating the movable linear module in the facing range facing toward the one fixed linear module, out of the plurality of linear modules arranged in parallel, is performed. At this time, a judgement process of judging whether or not the coordinate axis of the one fixed linear module and the coordinate axis of the movable linear module are continuous is performed. If it is judged that the coordinate axes are not continuous, the transfer operation is performed while the speed control is executed for the slider. Thus, it is possible to suppress the occurrence of a situation where the transfer operation of moving the slider between the movable linear modules cannot be performed due to the discontinuity of the coordinate axes respectively set for the movable linear modules.

  • Publication number: 20230142815
    Abstract: The transfer operation C of moving the slider between one fixed linear module M2 and the movable linear module M5 while locating the movable linear module M5 in the facing range Fb2 facing toward the one fixed linear module M2, out of the plurality of linear modules M1 to M5 arranged in parallel, is performed. At this time, a judgement process (Step S105) of judging whether or not the coordinate axis A2 (one coordinate axis) of the one fixed linear module M2 and the coordinate axis A5 (other coordinate axis) of the movable linear module M5 are continuous is performed (Step S105). If it is judged in the judgment process before the transfer operation C that the coordinate axes A2, A5 are not continuous, the transfer operation C is performed (Step S107) while the speed control (not the position control) is executed for the slider 4.

  • Patent number: 11626824
    Abstract: The identifier for identifying the slider is given to this slider. In contrast, the control signal transmitted to the plurality of linear drivers indicates the position command value and the speed command value for the slider and the identifier of this slider in association with each other. The linear driver reads the identifier for identifying the slider from this slider overlapping the assigned region thereof and supplies the current corresponding to the position command value and the speed command value associated with this identifier by the control signal to the linear motor stators. In this way, it is possible to cause the linear driver corresponding to the assigned region, in which the slider is present, to precisely drive the slider.

At this time, it is judged whether or not the coordinate axis of the one fixed linear module and the coordinate axis of the movable linear module are continuous If it is judged before the transfer operation that the coordinate axes are not continuous, the transfer operation is performed after the coordinate axes are made continuous in the direction by changing the coordinate axis. Thus, it is possible to suppress the occurrence of a situation where the transfer operation of moving the slider between the fixed linear module and the movable linear module cannot be performed due to the discontinuity of the coordinate axes respectively set for the fixed and movable linear modules.
