A device for weighing aircraft includes a weighing platform configured to receive a undercarriage leg of the aircraft and to generate weighing signals, a first calculation unit configured to calculate weighing information from the weighing signals generated by the weighing platform, a communication unit configured to transmit to a central device and to receive signals including at least one signal representing the weighing information calculated by the calculation unit, and a ground rolling unit configured to move the weighing platform over a surface.

For any weight change of items in a combination of discharge-target weighing conveyers selected by combinatorial computations during a standby state before the conveyers start to be driven, the combinatorial computations are executed again to select a new combination of discharge-target weighing conveyers, so that the items on the selected weighing conveyers that changed in weight are not transported to a collection conveyer without being possibly reselected into the new combination of conveyers. For any weight change of the items in the combination of discharge-target weighing conveyers during a transport-active state after the conveyers start to be driven, at least one of the collection conveyer or the weighing conveyer subject to the weight change is no longer driven or driven in an opposite transport direction, so that the items on the selected weighing conveyers that changed in weight are not transported into a packaging machine subsequent to the collection conveyer.

A method for processing pharmaceutical powders, which comprises providing a feeder module including a plurality of feeder units each with a storage hopper, a weighing cell, a conveyer, and a discharge end, connecting the storage hopper to a refilling system with a refilling valve, connecting the refilling valve to a level or weight indicator disposed above the refilling valve, connecting the discharge end to a common receiving container, refilling the storage hopper with a powder intermittently 40 to 80 times per hour, storing data during refilling, transporting powder from the storage hopper with the respective conveyer, and discharging powder from each feeder unit into the common receiving container. During each refilling of the storage hopper, the refilling valve dispenses powder into the storage hopper and, during the step of transporting the powder from the storage hopper, the conveyer is operated according to the data collected during previous refills.

A combination weighing device includes a plurality of weighing units arranged in a circular form, a combination scale configured to temporarily retain, in a collection hopper, articles discharged from one or more of the weighing units selected as a result of combinatorial computations and to discharge the articles from the collection hopper, and an alignment and transport unit configured to align and vibrationally transport the articles discharged from the collection hopper.

To provide a highly reliable combination weighing device having an object supply chute disposed above a dispersion section, which can prevent foreign matter from being mixed into objects due to the falling of screw members from a support frame supporting the object supply chute. A combination weighing device is provided with a dispersion section, weighing hoppers, a control unit, an object supply chute (150), and a support frame (100). The dispersion section disperses and supplies objects around the dispersion section. The weighing hoppers are arranged around the dispersion section. The control unit performs combination calculation based on weighing values in the weighing hoppers. The object supply chute is placed above the dispersion section and supplies the objects to the dispersion section. The support frame supports the object supply chute. The support frame includes members (111, 113, and 114) as engaged members, hooks as engaging members that engage with the engaged members, and fixing members (140) as non-screw members. The fixing members press the engaging members against the engaged members and fix the engaging members to the engaged members.

Provided is a dispersion and supply apparatus and a combination weighing apparatus capable of uniformly supplying articles to a plurality of positions from a dispersion table. A dispersion and supply apparatus 20 includes an acquisition unit 64 that acquires a load amount of an article on a dispersion table 22, a calculation unit 104 that calculates a deviation in a loading state of the article based on the load amount acquired by the acquisition unit 64, and a control unit 106 that controls a driving unit 30 such that a conveying direction of the article on the dispersion table 22 is changed based on the deviation in the loading state of the article calculated by the calculation unit 104.

Provided is a combination weighing apparatus having excellent sanitation. A combination weighing apparatus 1 includes: a plurality of weighing mechanisms 56, a weighing mechanism frame 80 which stores the weighing mechanisms 56, and a body frame 90 which supports the weighing mechanism frame 80, in which a normal to a surface of the body frame 90 is inclined with respect to a vertical direction.

A vibratory conveying apparatus (10) comprises a trough (20) for conveying articles from an upstream side to a downstream side, a vibrator (30) for vibrating the trough (20), and an attachment/detachment mechanism (40) for attaching and detaching the trough (20) and the vibrator (30). The attachment/detachment mechanism (40) has a trough-side attachment/detachment member (50), a vibrator-side attachment/detachment member (70), and a lever (65). The trough-side attachment/detachment member (50), which is secured to a trough bottom plate (21), has a protruding part (55) disposed on the upstream side and an eccentric cam (66) disposed on the downstream side. The vibrator-side attachment/detachment member (70), which is secured to the vibrator (30), has a protruding part (72) disposed on the upstream side and a bent part (73) disposed on the downstream side. The lever (65) is configured to be moved up and down to switch between a fixed state in which the trough-side attachment/detachment member (50) and the vibrator-side attachment/detachment member (70) are fixed to each other, and a separated state in which the two members are separated from each other.
