A step down product conveying and accumulation system employs one or more conveyors with a product path section, on which products are conveyed, and an accumulator section, for accumulation of products for recirculation and eventual delivery to a downstream destination. A length of the product path section is located within a first transverse plane. The accumulator section is located within a second transverse plane, in spaced apart relation with the product path section. A transfer surface in the form of a slide plate, air slide plenum system, or other low resistance or frictionless surface is employed as the transfer medium. Rather than transporting products, which are not properly aligned or which are unstable, for immediate delivery downstream, or for accumulation such that they reach the turbulence point which may cause system disruption, such products are transferred for accumulation by traveling smoothly and efficiently from the product path section downwardly on the transfer surface, onto the accumulator section. From there, the products are recirculated and properly aligned for ultimate, unencumbered downstream delivery.

The invention relates to a foldable pipeline peristaltic mechanism in the field of pipeline robots, comprising two movable platforms and a foldable connecting rod group flexibly connecting opposite sides of the two movable platforms; the movable platform is automatically expanded and contracted along the radial direction of the pipeline, Support the inner wall of the pipeline in the unfolded state, and separate the inner wall of the pipeline in the contracted state. Various devices or tools are mounted on the movable platform; the foldable connecting rod group can be automatically folded and set, and the folding direction is perpendicular to the unfolding of the movable platform , Shrinkage direction. The advantages are good rigidity and simple structure. After folding, the volume becomes smaller, which is convenient for people to carry and transport. After unfolding, it can be used for detection and flaw detection of large pipelines.

The invention relates to a body position tracking device for a child robot, which belongs to the field of robots and relates to a body position tracking technique when a child user is in different emotional states in interactions. The body position tracking device comprises an ultrasonic sensor, a pyroelectric sensor, a sound source positioning sensor and a vision sensor. By acquiring various sensor signals, and when sensor information is comprehensively fused and processed, the body position tracking device generates an action command data pack for an underside control system, thus action commands obtained by fusing and processing the sensor information are transmitted to a chassis stepped motor through a CAN bus so as to finish corresponding body position tracking actions. The robot of the invention has various body position tracking modes including slow-speed tracking, pasing, turning and the like, and can finish corresponding body position tracking aiming at different emotional states of the child user and meet the requirement on real-time interactions.

The invention discloses a winding mechanism, which comprises a frame and a winding rod. The frame is provided with a hinge support. The winding rod includes a long swing rod, a short swing rod, a connecting rod and a winding rod. Both the first end of the rod and the first end of the short swing rod are connected with the hinge support, the second end of the long swing rod is connected with the first end of the winding rod, and the second end of the winding rod is connected with a lead pipe , the second end of the short swing link is connected with the first end of the connecting rod, and the second end of the connecting rod is connected with the winding rod; the frame is connected with the first transmission device, the second transmission device and the drive device, and the drive The output end of the device is connected with the first transmission device, and the driving device works through the first transmission device and the second transmission device to drive the lead tube on the winding rod to do "8" movement; , to achieve automatic winding, improve work efficiency and save labor costs.

The invention discloses a control system of a liquid piston compressor. Electromagnetic valves are arranged on the intake pipeline and exhaust pipeline connected with the gas compression chamber of the liquid piston compressor, and the oil inlet of the first electromagnetic proportional speed regulating valve is respectively connected with the The oil outlet of the one-way variable hydraulic pump, the oil inlet of the two-position two-way electromagnetic reversing valve and the oil inlet of the relief valve are connected through pipelines, the oil outlet of the second electromagnetic proportional speed regulating valve, the two-position two-way The oil outlet of the electromagnetic reversing valve and the oil outlet of the overflow valve are both connected to the oil tank, and the oil inlet of the one-way variable hydraulic pump is connected to the oil through the oil pipe to form a pressure-stabilizing buffer structure, which changes the relationship between the liquid piston and the solid piston. The mode of action, during the movement of the piston from the top dead center to the bottom dead center, can effectively control and ensure the follow-up between the liquid piston and the gas piston, stabilize the gas-liquid two-phase interface, and reduce the surplus generated during the working process of the compressor. The gap volume realizes the efficient and stable operation of the compressor, and improves the adaptability of the liquid piston compressor to wide working conditions.

The invention discloses a clothes hanger flexible in clothes airing and collecting conversion and belongs to the field of clothes hangers. The clothes hanger comprises a rack, a drive mechanism, pulley mechanisms, an airing mechanism and a transmission rope. The drive mechanism comprises electric push rods, a push plate, slide blocks and guide rails. The electric push rods are connected with the push plate. The two ends of the push plate perform linear motion on the guide rails arranged on the two sides of the rack respectively through the slide blocks. The airing mechanism comprises clothes airing rods, hooks and nylon straps. The clothes airing rods are connected to form a curtain-shaped clothes airing panel through the nylon straps arranged on the two sides of each clothes airing rod, and the hooks are installed on the clothes airing rods according to a certain arrangement sequence. One end of the transmission rope is connected with one end of the clothes airing panel, wound around the pulley mechanisms sequentially and then connected with the other end of the clothes airing panel, and the transmission rope is connected with the push plate. According to the clothes hanger, flexible conversion of clothes in the vertical direction and the horizontal direction is achieved; furthermore, in the vertical direction, the clothes automatically get close and is folded in order; in the horizontal direction, the clothes is automatically unfolded for airing; accordingly, the clothes hanger is flexible in collecting and airing conversion and easy and convenient to operate.
