  • Patent number: 6612425
    Abstract: A conveyor system which has a continuous path conveyor is to be used for transporting and accumulating excessive loads. The conveyor may be formed of a continuous loop of chain elements. The conveyor path consists of two or more product carrying sections and corresponding offset return path sections. A product carrying section of the conveyor wraps around power driven sprockets where it is fed into and becomes a return path section. From there the path is guided over and aligned with free turning tail sprockets, where it is returned as a product carrying section. This section is then fed onto second drive sprockets, powered by another power means, where it again becomes a return path section, guided over tail sprockets and returned as a product carrying section. In this manner, the load of the conveyor chain is relieved at each drive sprocket assembly, thereby increasing the available working distance of the system.

  • Publication number: 20030079966
    Abstract: The article conveyor module has a drive system comprising a support plate on which there are mounted a synchronization pulley and a drive belt engaging said synchronization pulley. The synchronization pulley is for coupling to the drive belt of another conveyor module for the purpose of synchronizing the two conveyor modules. In this conveyor module drive system, the synchronization pulley is mounted outside the drive belt. The drive belt of the other conveyor module can also engage the synchronization pulley while remaining on the outside thereof. With this configuration, synchronizing two conveyor modules does not require an intermediate synchronization belt to be installed.

  • Patent number: 4815673
    Abstract: Two production lines for the manufacture of armatures or stators for electric motors are separated over at least part of their length by a common partition. The juxtaposed proximity of the two production lines allows operations on articles on both lines to be carried out simultaneously by equipment mounted on a common operating head. Shuttles are provided upstream and downstream of coil winding areas so that armature or stator bodies from one production line can be automatically diverted to a winder on the other production line and returned when wound. The height of the laminations is determined by picking a stack close to the maximum height permissible, measuring this height and, if necessary, removing a lamination via a vacuum line mounted on a measuring head. After winding, the ends of the magnetic wires on the armature are stripped using a laser.

  • Patent number: 4768642
    Abstract: The invention is generally accomplished by providing a plurality of conveyors to which are attached material handling devices. For at least a portion of their travel the material handling devices each travel in the same track or path, although they are attached to separate conveyor mechanisms that travel parallel with each other. This allows the material handling devices attached to one belt to operate at one speed for loading of product and to stop or operate at a different speed for unloading but use the same loading and unloading stations. Each conveyor is independently driven and controlled and each of the parallel conveyors is provided with a series of material handling devices attached to a portion of the conveyor.

  • Patent number: 4744458
    Abstract: A vibratory conveyor for advancing stacked wafer-like articles in an edgewise upstanding orientation includes a vibratory trough having a vibratory base portion of a width which is less than the width of the entire vibratory trough. The conveyor further has a non-vibratory, elongated base component situated adjacent the vibratory base portion and having a width which, together with the width of the vibratory base portion constitutes substantially the width of the entire vibratory trough. In response to an operational parameter of the vibratory conveyor, the articles are caused to be disengaged from the vibratory base portion and engaged solely by the non-vibratory base component, whereby conveyance of the articles is interrupted.

  • Patent number: 4720967
    Abstract: In the transport apparatus for roving bobbins in a plant including a group of spinning machines according to our invention each spinning machine has a closed circulating belt on which suspended carriages equipped either with full or empty roving bobbins are movable. A transport belt is provided which runs through a loading station which replaces empty roving bobbins with full roving bobbins. Each of the circulating belts is connected with the transport belt by one connecting belt for removing one of the suspended carriages with empty roving bobbins and another connecting belt for feeding in another suspended carriage with full roving bobbins. A switch controllable depending on the filling state of the approaching roving bobbin carriage is positioned at each branch of the connecting belts with the transport belt or one of the circulating belts. The roving bobbins are mounted on the transport and circulating belts so as to be movable independently of each other.

  • Patent number: 4719694
    Abstract: A production facility is provided for automatic assembly and testing of electronic card modules. Heretofore it has only been possible to manufacture card modules in batches without a quick conversion to another type of production, as required, being economically possible. This disadvantage is avoided by the present invention in that all required operating elements (component parts, tools, automatic assembly and testing units) are controlled in direct access with set-up time approaching zero for the production line via an extensive computer hierarchy in which the assembly and test line are available. A master computer administers the cell computers assigned to the individual processing stations which, in turn, control the machine computers. The conveying system has its own control available.

  • Patent number: 4704851
    Abstract: A power-driven structure comprises a long grider (I) supported at its both ends by self-propelled carriages (II) which raise and lower the girder, the implement being designed for travel across planted fields or orchards without compacting the soil. Various implements, such as a cotton harvester (34), a potato picker (VIII) or a fruit collecting device may be suspended from, and propelled along, the girder (I). A mechanical conveyor (15) extends along the top of the girder, and a pneumatic conveyor system (13) is arranged underneath the mechanical conveyor. The pneumatic conveyor system is provided with spaced nozzles (40) for connection to flexible suction pipes (34).

  • Patent number: 4593808
    Abstract: For a multi-level rack-type conveyor having a multiple series of racks connected end-to-end to form an endless loop supported on a central standard, a rail-and-roller configuration which provides for each series of racks, an upper, inwardly-facing vertical rail surface and a lower, outwardly-facing vertical rail surface having a free upper edge. Each rack is provided with a pair of upper and lower rollers to engage the respective vertical surfaces, the lower roller having a flange adapted to ride on the free upper edge of the lower rail surface to provide vertical support for the rack. The free edge engages in the corner between the flange and the vertical roller surface to enable the flange to roll on the upper edge without slippage which causes friction and consequent noise and wear.
