  • 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.

A magnetic field produced by the magnet or by the magnetic rotor rotates the rollers as they pass the magnetic field or as the magnetic field is changed. In one embodiment, the magnetic field is in the form of one or more switched reluctance motors.

  • Patent number: 8430233
    Abstract: The transport of work carriers on an assembly line is performed by the use of novel linear motors in which the primary part has both solenoids and permanent magnets and in which the secondary part has no permanent magnets of its own. By the provision of a magnetically soft plate, a work carrier has uniformly spaced clearances with respect to the secondary part and can be moved by the suitably arranged primary part. On an assembly line, it can be provided that the primary parts supplement the unction of an existing transporting bet. It may also be provided that a transporting belt is completely replaced by such primary parts.

  • Publication number: 20120305368
    Abstract: For a chain conveyor system having a main conveyor having links with an inclined or a slippery wet conveying run extending from a feed end to a discharge end capable of securely attracting and retaining metallic magnetic articles on the run by article-attracting magnet pieces in selected links for attracting and retaining the articles on the run. An auxiliary conveyor for enabling separation of the articles from the conveyor at the discharge end of the run by releasing attraction of the articles. The auxiliary conveyor has links which register with the main conveyor links at the discharge end of the main conveyor system. The registering links of the auxiliary conveyor have article-separating means operable to reduce the magnetic force of the magnet pieces at the discharge end of the run to enable separation of the conveyed articles from the main conveyor.

  • Patent number: 8297608
    Abstract: A transport system for conveying sheet material along a feed path. The transport system includes an electro-dynamic propulsion system for moving sheet material, or a stacked collation of sheet material, along a support deck which defines the feed path. More specifically, the electro-dynamic propulsion system includes at least one guideway and a ferromagnetic element disposed internally of the guideway. The guideway includes a magnetic coil to produce a variable magnetic field. By varying the flux density and polarity of the magnetic field the ferromagnetic element may be propelled within the guideway. An abutment member is coupled to the ferromagnetic element, extends through the elongate opening of the support deck and engages an edge of sheet material. A processor is operative to control the electro-dynamic propulsion system and, accordingly, the rate of travel and position of the sheet material along the feed path.
