  • Patent number: 7080727
    Abstract: A system, apparatus and method for the handling, transport and or storage of items of wearing apparel which are hung on hangers. In the system, there is plurality of transport units which travel over a rail system from a first location (e.g. an inbound location) to a second location (e.g. an outbound location). Each transport unit has a carrier section which, in the first operating position of the transfer unit, is generally horizontally aligned, and is suspended from a rail by means of first and second roller support sections at opposite ends of the carrier section. The transport unit has a second operating position where the carrier section is rotated relative to one of the roller support sections to a more vertical orientation where the garment units are closer together in a horizontal direction and more vertically aligned with one another, this being a position in which the garment units can be stored and/or shipped in a more closely packed configuration.

  • Patent number: 6602038
    Abstract: A conveying apparatus conveys articles used for manufacturing semiconductor devices. The conveying apparatus has a conveying rail section that includes a first rail providing a first conveying route, a second rail providing a second conveying route, and an intermediate rail structure interconnecting the first and second rails. Respective vehicles are fitted to the first and second rails so as to convey articles as supported atop the first rail or as suspended from the second rail, respectively. The conveying apparatus can be readily installed in the bay of an automatic manufacturing system, e.g., of a type for processing wafers having a diameter of 300 mm. In this case, the conveying route of the articles is unified, and space is saved, as well.

  • Patent number: 6554127
    Abstract: The invention relates to a power & free conveyor which comprises a free rail (3) and a power chain (1) that follows said free rail (3), to a large extent, in a parallel manner. A transport carriage (4) provided with a front runner (5) and a rear runner (6) are arranged on the free rail (3). The front runner (5) and the rear runner (6) each comprise a carrier (11, 14) that can pivot between two positions. In an area of the movement path of the transport carriage (4), the course of the power chain (1) deviates from that of the free rail (3) so that the transport carriages (4) can no longer be moved via the front runner carrier (1) thereof. Instead, the transport carriage is pushed by the interaction between a chain carrier (2) and the rear runner carrier (14) that is swung out into a carrying position. The rear runner carrier (14) comprises two stabile positions which can be changed by overcoming a resistance.

  • Publication number: 20030075415
    Abstract: Hanging conveyance equipment according to the present invention comprises a carriage, a number of work supports and a work hand. The carriage travels along a horizontal travelling path, which has stop positions arranged along it. Each of the work supports is fixed below one of the stop positions. An amount of work-lifting positioning and an amount of work-lowering positioning are set for each of-the work supports. The work hand can hold a work W hanging from it. The work hand is supported by the carriage in such a manner that the work hand can be positioned horizontally two-dimensionally with respect to the carriage. The work hand can vertically move with respect to the carriage to load a work onto or unload a work from each of the work supports. When the work hand is lowered from the carriage in each of the stop positions to lift a work from the associated work support, the work hand is positioned horizontally two-dimensionally in accordance with the amount of work-lifting positioning for the support.

    Abstract: A chain conveyor assembly having the combination of a polymeric material and a hard diamond-like coating at the frictional interface of the chain links. The conveyor chain preferably includes male and female links connected to one another by connector pins. The shaft of each connector pin is coated with a diamond-like coating having high hardness, low friction and low wear characteristics. Opposite ends of the connector pins are connected to the female link while the shaft of the connector pin passes through the male link. A polymeric bushing is fitted to the male link in engagement with the shaft of the connector pin. Accordingly, relative movement between the links occurs at the interface of the DLC connector pin and the polymeric bushing.

    Abstract: A control system and method for a conveyor line having a conveyor for moving a plurality of hangars configured to carry units through processing areas for processing by equipment in the processing areas includes loading stations for entering process control variables corresponding to units loaded at the loading stations, a pair of conveyor sensors for sensing movement of the hangars and outputting signals indicating the passage of hangars, and a controller. The controller determines, based on the process control variables, the time required for the processing equipment to reach steady state conditions. The controller further determines, based on the signals from the conveyor sensors, the appropriate time for loading units onto hangars such that the unit reaches the processing equipment when the equipment has reached the steady state conditions.

  • Patent number: 6464067
    Abstract: The invention relates to a method and device for buffering with the use of a closed gripper. The invention comprises transport means (20) which are provided with grippers (22), can move along a conveying section (10), and are located in the area of a buffer section (14) of the conveying section (10). Transport means are stored in such a way that the distance between the transporting means (20), said means being successively arranged in the buffer section (14), is essentially determined by the degree of opening of the grippers (22) or by the dimensions of the transport means (20). Said means are also stored in such a way that opened grippers (22) are at least partially closed without exercising a holding function in or before the area of the buffer section (14). To this end, a closing device is placed in an entry area (16) of the buffer section (14) which, for example, can be provided in the form of a closing connecting member (18) and can be displaced along the conveying section (10).
