Patent number: 12352617Abstract: Methods and systems for eccentric load error correction are disclosed. A plurality of weighing data sets for a weight having a mass value are obtained, where the weight is loaded at different positions on a weighing platform of a weighing device. Differences between each of the weighing data sets and the average value of the plurality of weighing data sets or the mass value of the weight are calculated. Sensor correction coefficients are calculated and updated when the maximum absolute value of the differences exceeds a pre-set threshold. The weighing data sets are updated. The above steps are repeated until the absolute values of all the differences are less than the pre-set threshold.Type: GrantFiled: July 8, 2021Date of Patent: July 8, 2025Assignees: Mettler-Toledo (Changzhou) Measurement Technology Ltd., Mettler-Toledo (Changzhou) Precision Instruments Ltd., Mettler-Toledo International Trading (Shanghai) Co., Ltd.Inventors: Shenhui Wang, Yujuan Zha, Song Zhang, Genjun Ji, Qiang Fu, Jinkang Han, Jinli Li

Patent number: 12332109Abstract: A method for configuring a calibration mechanism in a force sensor (100) has the steps of: coupling an end of the calibration lever (1071) to a loading end (102) of the force sensor; adjusting, in a no-load condition, the center of gravity (G0) of the unloaded calibration lever (1071), so that the center of gravity (G0) lies on a horizontal line (H) through the center of a calibration lever fulcrum (1031) at a fixed end (103) thereof; and adjusting, in a full-load condition, the center of gravity (G1) of the calibration lever (1071) loaded with the calibration weight (106), so that the center of gravity (G1) lies on the horizontal line (H) through the center of the calibration lever fulcrum. The calibration error caused by inclination in the force sensor is reduced by practice of this method.Type: GrantFiled: June 23, 2021Date of Patent: June 17, 2025Assignees: Mettler-Toledo (Changzhou) Precision Instruments Ltd., Mettler-Toledo (Changzhou) Measurement Technology Ltd., Mettler Toledo International Trading (Shanghai) Co., LtdInventors: Lei Xu, Jean Christophe Emery, Li Yang

Patent number: 12313443Abstract: A method of weighing using a scale (10) comprises the steps of: recognizing at least one of a plurality of objects placed within an object recognition area (A) of a platform (20) of the scale (10), and weighing the plurality of objects placed on the platform (20) of the scale (10) to determine a total weight of the plurality of objects. A weighing device (10) comprises the platform (20) configured as a plane, and utilizes the aforementioned weighing method. The method of weighing is advantageous in that it reduces the difficulty of object recognition using an algorithm by increasing the degree to which the object on the weighing platform fits the algorithm, reduces the complexity of the operation flow and the time required, and effectively increases the precision and accuracy of object recognition.Type: GrantFiled: July 29, 2020Date of Patent: May 27, 2025Assignees: Mettler-Toledo (Changzhou) Measurement Technology Ltd., Mettler-Toledo (Changzhou) Precision Instruments Ltd., Mettler-Toledo International Trading (Shanghai) Co., Ltd.Inventors: Song Zhang, Kan Liu, Shenhui Wang, Zhiqiang Wang, Kai Yin

Patent number: 12292324Abstract: These disclosures provide a weight stability control method for a deadweight force standard machine. For each weight in a sequence until all weights are loaded: weight platform is relatively rapidly moved downwards from an initial position, lifting a first-stage weight by a weight disk, and starting to load the first-stage weight starts; the first-stage weight is displaced relatively slowly when the first-stage weight communicates with a second-stage weight via corresponding lifting components for the first time; after the first-stage weight is completely separated from the second-stage weight, relatively rapidly displacing the weight platform downwards again until a gap between the first-stage weight and the second-stage weight reaches half of a pre-set gap value. The method provides control over the stability of the weights, effectively solving the weight shaking problem and improving testing efficiency.Type: GrantFiled: March 7, 2022Date of Patent: May 6, 2025Assignees: Mettler-Toledo (Changzhou) Measurement Technology Ltd., Mettler-Toledo (Changzhon) Precision Instruments Ltd., Mettler-Toledo International Trading (Shanghai) Co., Ltd.Inventors: Hanqing Xu, Leiyue Zhang

Patent number: 12276539Abstract: A method and device are provided for diagnosing a weighing system. In the method, the weighing system acquires an intrinsic parameter, a status parameter, and an operating parameter of various components of the weighing system, environmental parameters of the weighing system application, and communication data and interaction data among all the components. A first-level prompt is sent when the status of any of the components is abnormal, such that the system stops operating. A second-level prompt is sent when the status of each of the components is normal and the service life status of at least one of the components reaches a preset threshold. A third-level prompt is sent when the status of each of the components is normal and a system performance abnormality event is identified for the performance status of the system. A fourth-level prompt is sent when the status of each of the components is normal.Type: GrantFiled: June 2, 2021Date of Patent: April 15, 2025Assignees: Mettler-Toledo (Changzhou) Precision Instruments Ltd, Mettler Toledo (Changzhou) Measurement Technology Ltd., Mettler-Toledo International Trading (Shanghai) Co., Ltd.Inventors: Jianqiang Yang, Lifeng Cai, Jianwei Wu

Patent number: 12258217Abstract: A sorting device operates to shorten or lengthen a length of an upper portion of a travel path for a conveyor belt by reciprocating movement of sliding support surfaces at least partially supporting the conveyor belt. The reciprocating movement of the sliding support surfaces caused by rotational movement of a connected pivoting mechanism, which may be operated by an actuator located outside of an area defined by the travel path for the conveyor belt.Type: GrantFiled: May 15, 2023Date of Patent: March 25, 2025Assignee: Mettler-Toledo, LLCInventors: Christopher Wayne Sisemore, Michael Scott Evans, Kristofer Howell Loper, Willy Crouch

Patent number: 12228244Abstract: A mechanical apparatus levelling mechanism has a base (10), an adjusting screw rod (20), an adjusting plate (30) and a support plate (40). The adjusting screw rod penetrates into the adjusting plate in an axial direction and is connected to the base. The adjusting plate is located on the base; the support plate is mounted at a top end of the adjusting screw rod and is located above the adjusting plate; and the adjusting plate rotates to drive the adjusting screw rod to rotate, such that the support plate is adjusted vertically. This simplifies the operation procedure, improving the assembly accuracy and improving the working efficiency. The method is simple to operate. These adjusting mechanisms are convenient to move and simple to adjust, are time-saving and labour-saving, and have adjustment dimensions that can be quantified. Moreover, the installation is simple, and the adjusting mechanisms themselves can be reused.Type: GrantFiled: March 24, 2021Date of Patent: February 18, 2025Assignees: Mettler-Toledo (Changzhou) Measurement Technology Ltd., Mettler-Toledo (Changzhou) Precision Instruments Ltd., Mettler Toledo International Trading (Shanghai) Co., Ltd.Inventors: Shaowen Zheng, Dengyou Chen, Huaqiang Hui, Gang Wu, Qingsong Zhao, Long Qian, Pengbo Hao
