Patent number: 9417117Abstract: 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.Type: GrantFiled: December 10, 2014Date of Patent: August 16, 2016Assignee: ISHIDA CO., LTD.Inventors: Mikio Kishikawa, Shinji Takeichi

Patent number: 8776485Abstract: 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.Type: GrantFiled: February 2, 2012Date of Patent: July 15, 2014Assignee: Ishida Co., Ltd.Inventors: Satoshi Nishitsuji, Fumitaka Tokuda, Shinji Takeichi, Toshikazu Shimada, Toshiharu Kageyama, Toshikazu Shotsu

Patent number: 8198554Abstract: A load cell unit which can satisfactorily measure the weight of a measured object if ambient temperature changes, and a weight checker and an electric balance using the load cell unit, are provided. 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.Type: GrantFiled: August 24, 2007Date of Patent: June 12, 2012Assignee: Ishida Co., Ltd.Inventors: Kazufumi Naito, Shoko Tajiri, Shinji Takeichi
