Abstract:
The present disclosure concerns a system for transporting drill cuttings from an offshore drilling platform. In a representative embodiment, a bulk material storage and conveying system for a waterborne vessel comprises a first conveyor system including one or more upper conveyors extending lengthwise of the vessel. The system also comprises a plurality of containers located below the first conveyor system arranged in one or more rows, and a second conveyor system including one or more lower conveyors located below the one or more containers. The first conveyor system is configured to selectively dispense bulk material into the one or more containers, and the plurality of containers are configured to selectively dispense bulk material onto different locations along the length of the one or more lower conveyors. The system can further include an offloading conveyor assembly configured to convey drill cuttings from the lower conveyors to trucks on land.
Abstract:
The present disclosure is directed to a system for controlling dispersal of a granular material from a transport assembly. In an implementation, a system includes a transport assembly including a transport storage receptacle configured to receive granular material, and a payload deposit assembly coupled to transport storage receptacle. The payload assembly configured to disperse the granular material. A location-determining device coupled to the transport assembly. The location-determining device is configured to determine a position of the transport assembly with respect to a storage receptacle. A control mechanism is coupled to the transport storage receptacle, and the control mechanism is configured to control dispersal of the granular material. An electronic device is operatively coupled to the control mechanism. The electronic device is configured to allow dispersal of the granular material from the transport storage receptacle when the transport assembly is correctly positioned with respect to the storage receptacle.
Abstract:
An object loader system is provided for loading objects from storage into an object processing application. A first conveyor receives the objects from storage, and a second conveyor receives the objects from the first conveyor system at a predetermined location. A sensor determines detection of objects approximately relative to the predetermined location. The first conveyor conveys the objects to the second conveyor based upon the determined detection by the sensor.
Abstract:
Many types of processors of particulate materials operate more efficiently when they receive the particulate material in a steady stream. Most feeders tend to discharge in pulses. A hopper is interposed between the feeder and the processor. Surges in the feed rate are accumulated in the hopper, and lapses in the feed rate are compensated by the propensity of the hopper to discharge at a constant rate. Initiation of hopper flow is accomplished by use of a trap door. Mismatch between average feeder output rate and hopper discharge rate is corrected by use of an adaptive hopper having an outlet the size of which is slowly altered to maintain a constant amount of material in the hopper. A bypass hopper is used to control extremely variable input flow rates.
Abstract:
A linear variable capacity reservoir, particularly for rod-like articles of the tobacco industry, includes a boundary device (18;76) movable between an entrance (22;78) at one end and an exit (48;81) at the other end to vary the capacity of a main reservoir storage area (24;66). The boundary device (18;76) carries an end pulley (30;90) for a variable length extendible conveyor (32;88) which conveys a stream of articles from the main storage area to the exit. In another version the reservoir includes a movable end wall (216) movable towards and away from a stationary end wall (217) to vary the capacity of the reservoir storage area (220), and a variable length conveyor (218) extendible into the storage area from the stationary wall. When the storage area is empty a direct vertical path (212) for articles exists between the stationary and movable end walls. The extendible conveyors (32;88;218) are supportable by spaced retractable horizontal rollers (46) carried by vertical spindles (48).
Abstract:
An improved storage and discharge apparatus (10) for receiving items to be stored and selectively discharging same. The storage and discharge apparatus (10) comprises a depositary (14) for receiving items to be stored, the depository (14) defining a forward end portion (22) defining a discharge opening (26). The depository (14) further defines a bottom portion comprising a discharge conveyor (16) for supporting the items stored and for selectively discharging the items through the discharge opening (26). The apparatus also comprises a traveling loading mechanism (12) disposed above the depository (14) for depositing items to be stored into the depository (14). The loading mechanism (12) is longitudinally movable along substantially the length of the depository (14) and is selectively driven by a suitable drive. The loading mechanism (12) includes a cross-feed vibratory conveyor (50) having a vibratable tray (66) for receiving items to be stored, the tray (66) defining a slot (b 74) disposed above the depository through which the items are received. A movable wall (76) is disposed beneath the tray (66) rearward of the and adjacent to the slot (b 74), the movable wall (76) extending downwardly from the cross-feed conveyor (50) into the depository and being inclined toward the forward end portion (22) of the depository (14). In the preferred embodiment, the apparatus (10) is provided with an electrical control (94) for automatically controlling the loading and unloading of the depository (14).
Abstract:
For supplying tobacco from a redryer to a packer, the invention provides apparatus comprising four consecutive conveyors, the first conveyor operating continuously in one direction to feed tobacco from the redryer to the second conveyor, the second conveyor being reversible to act selectively as a holding conveyor and a supply tobacco to the third conveyor, the third conveyor being a weighing conveyor operated at a slower speed to weight and at a faster speed to deliver the weight quantities onto the fourth conveyor which carries the successive weighed quantities of tobacco to the packer. The conveyors are so controlled that the weighed quantities, when on the fourth conveyor, are spaced apart by intervals and the packer is operated through a packing cycle during each such interval.
Abstract:
The cigarette transfer assembly is provided with a chute adjacent the forward end of the horizontal conveyor in order to permit sliding of the flow of cigarettes and possible misalignment of the cigarettes due to different diameters along the surface of the cigarettes. A reservoir provided for a surplus of fed cigarettes is activated by two switches which are spaced apart to effect a reliable control of the reservoir in response to fluctuations in the flow of cigarettes supplied to the packaging machine.
