The latest technology progress of spinning machinery at ITMA ASIA+CITME 2022 were summarized. Taking the representative spinning equipment in the exhibition as examples, new products and innovative technology launched by famous domestic and foreign enterprises were highlighted, including carding machine, comber, drawing frame, roving frame, spinning frame, bobbin winder, two-for-one twister, new spinning machine and so on. It was pointed out that the exhibition focused on the themes of digital transformation, green development and cross-border integration of emerging industries, highlighted the concern from the spinning machinery industry for sustainable and smart solutions in the environment of gradual recovery of the global economy. It is considered that the development trend of spinning equipment is high efficiency, energy saving, digitalization, automation and intelligence. [ABSTRACT FROM AUTHOR]

In order to reduce the labor intensity of workers and achieve the automatic holding and placing of fiber bales for reciprocating automatic bale plucker, the structure of an AGV-based holding cart of the belt and packaging bag automatic removal machine for fiber bales was introduced. The holding device of the cart was designed. The dimensions of the holding gripper of the holding device were determined. The main mechanisms and parts of the holding device and its supporting part were designed and calculated. According to the working requirements, the parameters of the rack and pinion of the drive mechanism of the holding gripper were designed. The load of each oil cylinder was determined and the selection of the oil cylinder were performed by carrying out force analysis of the fiber bale and each component. Based on the design, the height of the holding gripper was 1 200 mm, and length of the holding gripper was 600 mm. The opening and closing range of the gripper was 660 mm to 910 mm. The working pressure of the oil cylinder of the gripper was 140 kg/cm². The diameter of the oil cylinder was 100 mm, and the stroke was 5 mm to 280 mm. The minimum working pressure of oil cylinder of the supporting machanism of the gripper was 0.97 MPa. The oil cylinder diameter was 80 mm, the rod diameter was 40 mm and the stroke was 400 mm.

Many challenges exist in the study of using orthotics, exoskeletons or exosuits as tools for rehabilitation and assistance of healthy people in daily activities due to the requirements of portability and safe interaction with the user and the environment. One approach to dealing with these challenges is to design a control system that can be deployed in a portable device to identify the relationships that exist between the gait variables and gait cycle for different locomotion modes. In order to estimate the knee and ankle angles in the sagittal plane for different locomotion modes, a novel multimodal feature-decoupled kinematic estimation system consisting of a multimodal locomotion classifier and an optimal joint angle estimator is proposed in this paper. The multi-source information output from different conventional primary models are fused by assigning the non-fixed weight. To improve the performance of the primary models, a data augmentation module based on the time-frequency domain analysis method is designed. The results show that the inclusion of the data augmentation module and multi-source information fusion modules has improved the classification accuracy to 98.56% and kinematic estimation performance (PCC) to 0.904 (walking), 0.956 (running), 0.899 (stair ascent), 0.851 (stair descent), respectively. The kinematic estimation quality is generally higher for faster speed (running) or proximal joint (knee) compared to other modes and ankle. The limitations and advantages of the proposed approach are discussed. Based on our findings, the multimodal kinematic estimation system has potential in facilitating the deployment for human-in-loop control of lower-limb intelligent assistive devices.
