Abstract: A combination weighing apparatus includes a plurality of hoppers and a collecting chute. Each of the plurality of hoppers has a main body provided with a first opening and a second opening, and a gate allowed to be opened and closed with respect to the second opening. The main body is provided with a first inner surface and a second inner surface having an intersecting positional relationship to protrude outward with respect to the centerline. The collecting chute has at least a chute portion configured to receive articles discharged from the plurality of hoppers and slide the articles. A portion of the chute portion located below the plurality of hoppers is provided with a first receiving surface and a second receiving surface having an intersecting positional relationship to protrude outward with respect to the centerline.

Abstract: A hopper includes a main body having a first opening to which articles are thrown in and a second opening from which the articles are discharged, a gate capable of being opened and closed with respect to the second opening, a restricting portion configured to restrict an opening and closing operation of the gate with respect to the second opening, and an attaching portion capable of being attached and detached with respect to an attached portion provided on a weighing apparatus. The restricting portion starts restricting the opening and closing operation in a state where the gate is closed with respect to the second opening in conjunction with an operation of detaching the attaching portion from the attached portion.

Abstract: A weighing device is equipped with a first overload protection mechanism and a second overload protection mechanism. The first overload protection mechanism includes a first support portion disposed on a fixing member and a first section disposed on a connecting member. The second overload protection mechanism includes a second support portion disposed on the fixing member and a second section disposed on the connecting member. When a first load acts on a weigh hopper, the first support portion supports the first section from below. When a second load greater than the first load acts on the weigh hopper, the second support portion supports the second section from above at the same time that the first support portion supports the first section.

Abstract: A form-fill-seal machine is capable of reducing poor sealing caused by a packaged article catching in lateral seal portions. The form-fill-seal machine is provided with an upper tube, a lower tube disposed therebelow, a former, a lateral sealing mechanism below the lower tube, and opening and closing sliding members. A packaged article is dropped through the interiors of the upper tube and the lower tube. The former winds a sheet of a film F around the circumference of the lower tube to convert same into a tubular film. The lateral sealing mechanism laterally seals the tubular film. The opening and closing sliding members, which are disposed between the upper tube and the lower tube, shut off an upwardly oriented flow of gas from the interior of the lower tube when in a closed state.

A strain generating element includes plural strain generating portions. Each of strain gauges is a gauge of a temperature/sensitivity compensated type and is placed in a position on a corresponding strain generating portion. A bridge circuit includes the strain gauges. A zero compensation element compensates the zero of the bridge circuit in accordance with the temperature of the strain generating element, to roughly correct an output of the bridge circuit. A thermal sensitive resistor is a temperature sensor for detecting the temperature of the strain generating element. The zero compensation element and the thermal sensitive resistor are provided on a thick portion interposed between adjacent strain generating portions. A signal processor minutely corrects a roughly-corrected output of the bridge circuit.
