Part installation method of part assembly line

The invention provides a part installation method of a part assembly line. The part installation method realizes no overlapping of motion paths of operators performing part supply work related to types of substrates in production and part preparation work related to types of substrates to be produced, guarantees high operation efficiency and largely prevents production halts during the production of multi-operation production mode. In the part installation of the part assembly line with multiple stages of part installation machines arranged in parallel, the following steps are conducted in each stage of the part installation machines: the types of substrates produced according to the production order are distributed to substrate types on sides of first and second part feed devices alternatively; when a part transfer device selects parts from one of first and second part feed devices and installs the parts on substrates of the substrate types on the side of one part feed device, part receiving devices are disposed on the other part feed device; and the part receiving device are used for receiving parts being produced after production of the substrate types on the side of one part feed device and being of the types for the substrates of the substrate types on the side of the other part feed device.

Smooth brake control system of multiple constant-tension anchor gears for pipe-laying ship

The invention discloses a smooth brake control system of multiple constant-tension anchor gears for a pipe-laying ship, comprising a cockpit operation control center and a remote anchor gear engine room control device. The cockpit operation control center is connected to the remote anchor gear engine room control device through an optical cable and used for controlling the multiple anchor gears and collecting traveling state data of the multiple anchor gears. A bow anchor gear control platform and a stern anchor gear operation control platform are in interactive transmission with information of controlling the anchor gear and the operation control center of the engine room cab through a control bus; the control device of the remote anchor gear engine room connects the bow linkage control cabinet, the stern linkage control cabinet to the main control station of a cockpit monitoring center in order to realize the data collection and monitoring of all operation control cabinets in the cockpit. The invention reduces production downtime, realizes smooth braking of multiple anchors, guarantees working state of multiple anchor gears and thus realizes the smooth movement and positioning of the pipe-laying ship.

Underground mine ventilating system and air quantity distribution method

ActiveCN110953010AReduce the number of mining pits at the same timeIncrease ventilation timeTunnel/mines ventillationAir volumeMining engineering
The invention provides an underground mine ventilating system and an air quantity distribution method, and aims to solve the problem of simultaneously mining and ventilating for multiple middle sections of an underground mine. The constructed mine ventilating system takes a panel as a smallest ventilating unit; a special tail gate is utilized as a panel tail gate, and a gate which does not take the main function is taken as a panel main air inlet gate which communicates with each mining sub-section gate through a panel air-return inclined drift; an air flow purifying device and a cooling and heat exchange device are arranged in the panel air inlet gate, so that inlet air flow is purified and cooled; and a mine ventilating system with a function of isolating contaminated air from fresh airis formed. In the constructed ventilating system, two panel air quantity distribution methods are disclosed, the first method refers to controlling section dimension of each air-return inclined driftin each panel to balance air quantity of each panel, and the second method refers to arranging an intelligent regulating air window in the air-return inclined drift and a disc air-return stone gate linked with the tail gate to regulate ventilation amount of each panel.

Method for predicting the presence of product defects during an intermediate processing step of a thin product wound in a roll

Method for predicting the presence of product defects during an intermediate processing step of a thin product wound in a roll, which provides for—receiving a roll of thin product that has been assigned a unique identification code stored in a database system, this latter containing process and/or product parameters detected in the production steps of said thin product wound in said roll upstream of said intermediate processing step, associated with said unique identification code,—accessing said database system,—entering one or more of the process and/or product parameters associated with the unique identification code of said roll contained in said database system in a predictive model, which uses a correlation, created by means of machine learning logics, from historicized values related to the process and/or product parameters output from said intermediate processing step and historicized values related to process and/or product parameters of the same rolls detected in the production steps of said rolls upstream of said intermediate processing step, in order to predict product parameters output from said intermediate processing step,—comparing said aforesaid product parameters with respective predefined limit values,—generating predictive diagnosis information of thin product defects based on the result of said comparison.
