Abstract: A system and method are set out for the sorting of articles wherein at least one conveyor belt is used to convey and article to a storage unit. The storage unit comprises a plurality of vertically displaceable storage units having compartments. The compartments are defined by walls which extend at a non-perpendicular angle to the vertically displaceable storage units. The walls of the compartments are adjustable to adjust the space defined by the compartment. The vertically displaceable storage units are individually vertically displaceable so as to receive an article from one direction and make other articles available for removal from a second direction. The storage unit is appropriately rotatable about a central axis.

Abstract: A loading apparatus for vertically stacking a plurality of articles includes a staging assembly. The staging assembly includes a staging platform configured to receive and support the articles. The staging platform is vertically movable to a plurality of vertical levels. The staging assembly further includes a lift drive to raise and lower the staging platform, and a positioning system to move the articles off of the staging platform at selected ones of the plurality of levels. A conveyor assembly is configured to transport the articles to the staging assembly. The positioning system may be operable to remove the articles from the conveyor assembly and position the articles on the staging platform. The positioning system may be operative to position the articles on the staging platform while the lift drive is raising or lowering the staging platform.

Abstract: An elevator ice tray storage apparatus includes astorage bin and an elevator platform assembly overlying the bottom of the storage bin. The assembly includes a base member which slides on the bottom of the storage bin, and a platform for elevating an ice tray into a first elevated storage position. A handle and guides are provided for facilitating the manipulation of the elevator assembly. Rollers are provided at the back end of the platform for rolling against the back end wall of the storage bin was the elevator assembly elevates an ice tray. One or more elevated storage positions are provided, each having hinged flaps that rotate out of the way to allow a tray to pass by as it is being elevated and which rotate back to a flat repose position, on which side edges of a tray are lowered to rest.

Abstract: An apparatus and method for controlling wafer temperature and environment is provided. The apparatus includes a batch processing fixture for batch processing wafers at a first elevated temperature. The batch of wafers is not substantially ramped in temperature within the batch processing fixture. The apparatus also includes a single wafer processing apparatus for rapidly ramping temperature of a wafer of the batch from the first elevated temperature wherein a uniform temperature across the wafer is maintained during the ramping. Another embodiment of the apparatus (10) includes an RTP chamber (20) having an inert or reducing environment and that includes a pedestal (24) for holding a single wafer (16) and a heater unit (22) arranged so as to uniformly and rapidly heat the single wafer.

Abstract: A workpiece-carrier changeover apparatus removes a workpiece carrier from a storage unit and moves it in a first direction into a buffer storage position. Any workpiece carrier in a supply position is then moved back toward the storage unit either simultaneously with that movement or thereafter so that the workpiece carrier in the buffer storage position can be moved into the supply position.

Abstract: Parts P are fed from a tray parts feeder 1 in which trays 3 loaded with parts P in rows thereon are accommodated. Mount head 18 mounts the parts P onto a substrate 5 that is carried in along guide rails 6 of a substrate transfer section 4. A tray 3 is drawn out from the tray parts feeder 1 by a given pitch and positioned at a predetermined location. The apparatus has a construction such that the tray 3, as it is pulled out, passes under guide rails 6 of the substrate transfer section 4.

Abstract: An automated feed mechanism (2) for retrieving a desired wafer assembly (20). The automated feed mechanism (2) has an elevator assembly (12) for storing a plurality of wafer assemblies (20) and the elevator assembly (12) is driven to facilitate retrieval of the desired wafer assembly (20). A pick and place assembly (16) retrieves electronic components (22), from a retrieved wafer assembly (20), and transports each retrieved electronic component (22) to a shuttle assembly (18). The shuttle assembly (18) comprises first and second shuttle platforms (34, 36), with one of the shuttle platforms (34 or 36) located adjacent the pick and place assembly (16) for loading electronic components (22) thereon, and the second shuttle platform (36 or 34) located at a dispensing position (D) for retrieval of the previously loaded electronic components (22) by an automated assembly machine (3).

Abstract: The present invention provides a wafer positioning device having wafer storage capability. The wafer positioning device has a wafer platform with wafer lift pins, a wafer position sensor, and a storage location in close proximity to the wafer platform and the wafer position sensor. The storage location may be above the wafer position sensor, in which case the wafer position sensor retracts or rotates so that the wafer lift pins may elevate a positioned wafer past the position sensor to the storage location. Alternatively, the storage location may be between the wafer platform and the wafer positioning device. The storage location is preferably formed by a plurality of rotatable towers or a plurality of retractable lift pins that are operatively coupled to the wafer platform and that have wafer support portions capable of assuming both a wafer storage position and a wafer passage position.

Abstract: A conveying system for conveying a substrate is provided with a sensor for measuring information related to flexure of the substrate during conveyance or the vertical position of the substrate. Conveyance of the substrate is controlled on the basis of the measurement by the sensor, whereby correct conveyance of the substrate is accomplished without being influenced by dispersive flexure amount of substrate.

Abstract: Of a plurality of wafers (15) circumferential edge portions of which are held by slot grooves (14) of a wafer cassette (13), the positions of a wafer (15) to be transferred and the wafers (15) above and beneath it are detected by a first sensor (16) and a second sensor (17). A calculating unit calculates an amount of bend of each wafer (15) based on the detected information. It is determine, based on the calculation result, whether the transfer arm (18) can be inserted under the wafer (15) to be transferred without contacting with the wafer beneath (15) and whether the wafer (15) to be transferred can be lifted up by the transfer arm (18) without contacting with the wafer above (15).

Abstract: Trays for temporary reception of accumulations of parallel cigarettes are being introduced into and withdrawn from open-sided containers for groups of trays. The containers are provided with partitions defining tray-receiving compartments in a predetermined distribution, and the trays are assembled into groups wherein the trays are arrayed in such a way that they can be pushed, as a unit, into an empty container whereby each tray of the array enters a discrete compartment. Analogously, a set of mobile suction-operated devices is used to simultaneously withdraw an entire group of arrayed trays from the compartments of a filled container. The introduction of groups of filled or empty trays into containers can take place at a first level, and the evacuation of groups of filled or empty trays from filled containers can take place at a different second level. The second level can receive filled trays from a tray filling unit and the first level can serve for delivery of empty trays to the tray filling unit.
