摘要:
An unloader for discharging and feeding dry, granular type materials from bulk bags. Among the many improvements of the discharge apparatus is an open frame (20) and offset discharge location. Other improvements include an I-beam (23) and frame design that keeps the hoist (25) movement within the four corner posts of the frame. The unloader may be provided with vibrators, vibration isolators, load cells, actuators (107, 108), massage paddles, or plates (106, 109) to assist in the discharge function.

The invention concerns an apparatus for successively emptying containers filled with articles, including a delivery element for delivering full containers to a transfer device, whereby the transfer device is designed as a pivot device which includes a pivot arm with a receptacle arranged at a free end and is pivotable about a pivot axis for pivoting out of a lower receiving position A into an upper emptying position E and back, as well as a removal element for removing the empty containers, which is distinguished by the fact that the receptacle at the free end has at least two chambers for receiving at least two containers. Furthermore the invention concerns a method in which, at the same time as emptying the container in the emptying position E, a container already emptied beforehand is introduced into the receptacle, and the empty container after pivoting back into the receiving position A is removed from the receptacle again, while at the same time a full container is introduced into the receptacle.

An object of the present invention is to minimize a fear of damaging parts when they are transferred from a carry-in cassette to a carry-out cassette and to shorten a transferring time. Tip end portions of a thrusting-down pin 30 and a suction collet 50 are brought into contact with a back face of an adhesive sheet 11 of a carry-in cassette 10 to thrust down a semiconductor chip 1 and the thrust-down semiconductor chip 1 is received on a carry-out cassette 20A, 20B, or 20C and stuck on an adhesive sheet 21A, 21B, or 21C of a receiving face 201A, 201B, or 201C of the carry out cassette 20A, 20B, or 20C.

摘要:
A die pickup method and device including a collet 4 that vacuum-chucks dies 1A, 1B, IC . . . , which are on a wafer sheet 2, and a suction stage 6, which vacuum-sucks this wafer sheet 2. A protruding surface 21 is formed on the upper surface of the suction stage 6 so that it is located on the feeding (upstream) side in the direction in which dies are fed to the die pickup center 5 of the suction stage 6. The wafer sheet 2 being vacuum-sucked by the suction stage 6 is fed so that a die 1A that is to be picked up is moved toward the die pickup center 5, thus allowing the die 1A to be separated from the wafer sheet 2 as the die 1A passes the protruding surface 21, and then the die 1A is vacuum-chucked and picked up by the collet 4.

A semiconductor wafer transfer equipment transfers a number of semiconductor wafers 51 that are held in grooves 52 of carriers 53 in the erected state to boat 54 using first and second wafer elevators 22 and 23 equipped with comb-teeth member 31 and wafer grip and transfer unit 24, and first and second wafer elevators 22 and 23 provided corresponding to carriers 53 and boats 54 are equipped with position correction mechanism 30 which corrects the positions of comb-teeth openings 34 of comb shape members 32 and 33 provided to comb-teeth members 31 corresponding to semiconductor wafers 51 housed in grooves 52 of carriers 53.
摘要:
A device and method for expanding the distance between individual multiwell plates of a stack of multiwell plates so that all the plates can be loaded at once into a magazine commonly used in automated analysis systems. Significant to the device are a series of inter-connected rails, each rail capable of supporting one plate. As the distance between the rails is increased, the stack of plates is expanded and will align with slots from a magazine loader. By using the device, a stack can be expanded in preparation for loading, or conversely, plates coming from a magazine can be restacked for storage.

A trash bag opener and removal apparatus has a feed conveyor, a housing assembly and a discharge conveyor for opening and removing plastic and paper bags filled with material and discharging the material at a chute end of the discharge conveyor. The bags are routed by the feed conveyor into the housing assembly, which has a separate input conveyor, a slicer assembly, a slitter assembly, a bag stripper assembly and first and second paddle wheels. The input conveyor is located proximate to the feed conveyor and travels faster than the feed conveyor to upset the bags and ensure that the bag bottoms are exposed for the slicer assembly. The slicer assembly has a rotating, cylindrical drum with three serrated blades along its length and oscillates to tear the bags open. The paddle wheels retard and assist in moving the bags and refuse from the slicer assembly to the slitter assembly, which has rotating notched disk blades to rip the bags open, and then to the discharge conveyor. The bags and refuse then pass beneath the bag stripper assembly, which has rotating, extending fingers that grab and remove the torn bags from the refuse. The fingers retract as the bag stripping assembly rotates and then drop the bags on top of the refuse. The discharge conveyor then moves the bags and refuse to the chute end for discharging the refuse.

A tilting mechanism for precisely controlling the pouring of metal from a melting crucible is disclosed. The mechanism utilizes a pressure roller journalled in an adjustable bearing mount to clearance-free urge a rack against a pinion to tilt the crucible. At least one boom is disposed on the adjustable bearing mount to pivot the hydraulic cylinder in a parallel direction relative to the tilting shaft.
摘要:
Articles, such as fragile, delicate semiconductor wafers, in a first carrier member are caused to pass nearly, but not quite wholly, into a second carrier member by being pushed--against gravity--thereinto. The carrier members are then subjected to a displacement, e.g. by inversion, and said articles are allowed to drop wholly into said second carrier member. The further distance travelled by the articles after rotational displacement of a housing retaining the carrier members is very small, e.g. about 2 mm.

A cover assembly is provided which is adapted for use on a receptacle transporting vehicle having a receptacle supporting scull frame swingable from a receptacle transport position to a dumping position for discharging molten contents of the receptacle. Included in the assembly is an insulated lid member for opening and closing the receptacle, the closure position retarding heat loss from the molten contents to preclude solidification during transport thereof between spaced locations. A pair of laterally spaced-apart support arms, mounted so as to move concurrently with the swingable scull frame, position the lid member adjacent the top of the receptacle during scull frame movement and especially during transport of the receptacle from one location to another. A pivot assembly rotates the support arms for similar movement of the attached lid between receptacle opening and closure positions, such movement being independent of the scull frame movement. An operator-actuated piston system selectively controls lid movement between the opening and closure position. The assembly is mounted to the scull frame to provide rotation of the lid in a direction away from and contra the rotational movement of the scull frame from the transport to dumping positions to preclude interference of the lid with the contents being discharged from the receptacle.
