A light emitting device mixer includes at least two bowl feeders, each including a bowl capable of holding workpieces, and a driving unit capable of causing vibration to the bowl. The bowl feeders include a moving passage through which the workpieces may move from one bowl feeder to an adjacent bowl feeder.

A supply device with which elements in disordered form, in particular connection elements as bulk elements, are suppliable to a second receiving volume. The supply device includes a first receiving container from which, via an outlet opening, a plurality of elements is deliverable to a second receiving container. The second receiving container may consist of an oscillation feeder. The oscillation energy of the oscillation feeder is specifically transmitted onto the elements, which are stored in the first receiving container. With the help of the transmitted oscillations, elements are transferred from the first receiving container via a transfer zone from the first receiving container into the second receiving container.

An object of the present invention is to provide a stepped pin loading mechanism which can be used for loading stepped pins, comprising a vibrator bowl. A spirally rising discharge track is connected to an outer side of a hopper of the vibrator bowl, and a swivel plate is provided on the discharge track, and several receiving slots are provided on the swivel plate. The strip-shaped receiving slot consists of an inner segment and an outer segment, and the width of the outer segment is greater than that of the inner segment. A front baffle and a rear baffle, both of which are provided with a through opening, are provided on the discharge track, an arc-shaped side baffle, which is located between the front baffle and the rear baffle to form a semi-enclosed structure, is provided on an outer circumferential side of the swivel plate. One end of the side baffle deviates from the through opening of the rear baffle, and the height of an upper edge of the side baffle gradually increases from the rear baffle to the front baffle so that an upper edge at the other end of the side baffle is as high as an upper side of the through opening of the front baffle.

An object of the present invention is to provide an oil seal distributing mechanism for a vibrator bowl, which is structured as follows. A feeding track of the vibrator bowl comprises a left side plate and a base plate, a through groove running vertically and taking a right side wall of the left side plate as its left side wall is provided at a portion of the base plate close to the left side plate, and a distributor, having a minimum distance L between its leftmost edge and the right side wall of the left side plate, is provided in the through groove; an oil seal has an outer diameter D, a maximum inner diameter d1 and a minimum inner diameter d2, where L>D-d1; a distance between front and rear walls of the through groove is greater than the outer diameter of the oil seal; the base plate is aslant arranged and/or a force applying mechanism is provided above the through groove, and the base plate gradually extends upward from left to right when the base plate is aslant arranged; and the force applying mechanism is configured to enable an edge of the oil seal close to the left side plate to flip down.

A system is disclosed for controlling the disgorging of objects. The system includes a container system including a container for containing objects, rotation means for rotating the container to a disgorgement angle, and movement means for moving at least a portion of the container system in a repetitious manner with a net zero distance of travel of the at least the portion of the container system such that the objects are disgorged from the container at a controlled rate of disgorgement.

A loading workstation comprises a docking station including a first transmission device adapted to transmit a carrier for loading components, and a mobile vehicle. The mobile vehicle includes a second transmission device, a feeding device and a loading device. The second transmission device is adapted to dock with the first transmission device to allow the carrier to be continuously transmitted on the first transmission device and the second transmission device. The feeding device is adapted to supply components to be loaded. The loading device is adapted to load the supplied components onto the carrier that has been transferred to the second transmission device.

A parts accumulating section includes a cylindrical center member; and a hose helically wrapped around the outer periphery of the cylindrical center member, and connecting two predetermined steps of a parts production line to each other. The hose has an inner diameter dimension which enables parts to pass, in a predetermined attitude, through the hose with only a respective one of the parts disposed in the hose in the radial direction of the hose. A vibration generating section applies torsional vibrations to the parts accumulating section so that the parts are fed through the hose. The parts discharged from the upstream step are accumulated in the hose in the same order as they are handled in the upstream step. The parts are fed through the hose without generating surface damage to the parts due to their collision against each other, and are supplied to the downstream step.

The proppants processing system comprises one or more in-feed conveyors, one or more out-feed conveyors, one or more primary feed bin assemblies, one or more secondary bin assemblies, the primary and secondary bin assemblies each comprising one or more bins and one or more bin conveyors. The proppants processing system further comprises a final transport conveyor and a control unit adapted to control flow of the proppants. A method of processing proppants, the method comprising the steps of providing proppants comprising dry or wet sand; using an in-feed conveyor, transferring the proppants from a transport vehicle to one or more bins of a primary feed bin assembly; moving the proppants from the one or more bins to a feed bin conveyor; moving the proppants from the feed bin conveyor to a final transport conveyor; and using the final transport conveyor, moving the proppants to a blender.

A circular distribution apparatus for distributing loose products has a top portion (17) with an inlet (19) positioned centrally relative to a vertical central axis, a base portion (7) comprising an annular horizontal floor (11); a plurality of openable and closable outlets (23) provided in the annular floor (11); a side wall (9) surrounding entirely the annular floor (11); a central elevation (13) disposed between the annular floor (11) and the inlet (19); and a vibrator (51) configured to vibrate the base portion (7) so that products received on the base portion (7) circulate around the elevation (13) on the annular floor (11). The top portion (17); the elevation (13); the annular floor (11); and the side wall (9) provide a housing (3) comprising a distribution chamber (5), where at least the elevation (13), the annular floor (11) and the side wall (9) are provided integrally.

In-feed device (1) for feeding objects onto a grading apparatus (13) for grading sensitive products. The in-feed device (1) comprises a new type of sliding plates (4, 5) and vibrating motors (7) to arrange the objects and to rinse small particles from the objects to be graded.
