  • Publication number: 20110017031
    Abstract: Apparatus and method for cutting boxes. The box cutter has a rectangular work area defined by the upper run of an oblique-roller conveyor belt selectively driven forward or reverse in coordination with the actuation and deactuation of the obliquely rotatable belt rollers. Cutting tools along the sides of the work area cut into the side panels of the boxes as they are translated without rotation in a rectangular path against guide surfaces on the periphery of the work area by the sequential reversing of the conveyor belt direction and the actuation and deactuation of the box-supporting rollers.

    Abstract: A method of operating an installation for conveying and sorting baggage items within an airport building, preferably between the check-in area and reclaim area for the baggage items and the loading units assigned to a certain flight. The installation has a complex electrically and/or electronically driven and controlled conveying and handling system for transporting, sorting, transferring, storing and checking the baggage items, which are transported in a state in which they rest loosely on conveyors or are located in containers. In order to configure a method of operating the installation such that, along with relatively low energy costs and relatively low levels of wear, it is possible to reduce the operating costs of the installation and the maintenance costs, it is proposed that it is possible for the power supply to individual suitable installation parts or components to be switched on and off in dependence on the state of occupancy of the installation and/or on the varying loading.

  • Publication number: 20090260950
    Abstract: In order to do away with the need for large items of laundry which are spread out by a spreading arrangement (12) such that they hang down freely upstream of the feed conveyor (11) to be raised manually, as they are fitted manually into loading clamps (27), until they hang down freely, it is known for the loading clamps (27) to be displaced to the spreading arrangement (12) on obliquely upwardly directed conveyors (20). The large items of laundry are thus raised mechanically. For this purpose, the loading clamps (27) are arranged on carriages which can be displaced on upwardly directed rails. The disadvantage here is that the empty loading clamps have to be moved downwards on the rail again by the carriage before the next item of laundry can be fitted into the loading clamps (27). The invention makes provision for the loading clamps (27) to be arranged on conveyors (20) having endless toothed belts (21). The loading clamps (27) can thus be driven in circulation.

  • Publication number: 20090250311
    Abstract: The invention relates to a method and to a device for creating a product flow according to a predefined sequence (S). The products (A, B, C) are fed from different feed flows of a grouping path (G) and there, according to the sequence (S), are deposited onto a conveyor (10,10) with a closed revolving path (U). According to the invention a repair function is realised in which the products (A, B, C) are then only transferred from the conveyor to a further-processing station if the sequence (S) is correct and all products (A, B, C) are present with the desired quality. Otherwise, the products (A, B, C) are led by the continuously operated conveyors (A, B, C) back to the grouping path (G). Here, the error is corrected by way of the deposition of the missing product (A, B, C), whilst the deposition of new products (A, B, C) is interrupted. For error correction, one may previously provide a discharge of a defect or wrong product (A, B, C).

    Abstract: A conveying system including multiple conveying tracks where each track acts as the output track from one operation and the input track to a subsequent operation. When the manufacturing process at a first operational area is completed, the completed product is placed on the area's output track and conveyed to a subsequent operational area. When the processing at the subsequent area is completed, the unit is placed on the subsequent area's output track, which is a physically distinct track from the area's input track. The input and output tracks within an operational area may occupy different levels of a multi-level system in which the various levels share a common floor space footprint to conserve floor space requirements. The tracks may be configured as a pair of tracks to facilitate simultaneous processing of two products or jobs. In addition, one or more of the tracks may have a support surface that is not parallel to the manufacturing floor.

  • Patent number: 6419071
    Abstract: A lowerator for an assembly system of the type including at least one rail defining a path of travel with respect to at least one workstation, and a conveyor for transporting a work piece along the rail. The conveyor includes a trolley moveable along the rail and a carrier moveable with respect to the trolley. The carrier supports a work piece during movement with respect to the workstation. The carrier is vertically positionable between a raised position and lowered position with respect to the trolley. The lowerator moves the carrier between the raised and lowered positions and cycles a latch for securing the carrier to the trolley when in the raised position. The lowerator includes at least one lifter or actuator defining a path of travel in at least a first direction, wherein the lifter actuates the latch to uncouple the trolley and carrier before moving the carrier into the lowered position at the workstation so that one or more processing operations can be performed on the work piece.

  • Patent number: 6318946
    Abstract: An interlock system prevents collision of handling equipment and damage to wafers in an automated wafer transport apparatus during manual control by an operator. Sensors are used to sense when wafer transport arms and wafer stage are both in their home positions. A controller is responsive to the sensors for operating the lockout system such that attempted activation of the transport arm by the operator is locked out unless both the stage and the arms are in their home positions. The lockout system preferably comprises normally closed electrical relays.

  • Patent number: 6264420
    Abstract: A device is provided for monitoring sheets from which cards with a monetary value and/or identity cards are punched, where the cards are arranged in rows on the sheets. The device is configured such that the number of cameras used is independent of the number of rows of cards. The device has a table on which at least two sheets can be laid. A camera can be moved along and across the table, and a conveyor device travels along the table above the camera.
