Research On Key Techniques Of Multi-Color Square Mosaic Automatic Tiling Machine

The multi-color mosaic automatic tiling machine is an equipment capable of assembling mosaic tiles of various colors and producing colorful mosaic pattern products,which can be used to replace traditional artificial tiling methods,thereby improving the production efficiency and reducing cost.However,current mosaic tiling machines can only support single color or random pattern without cost-effective,had not been widely used.Based on the relevant research and existing achievements of our research group,a novel tiling machine is proposed.The mechanical structure of is designed and some key technologies studied,the successful operation of the prototype proved the feasibility.The research results of mosaic tiling automation is summarized,after detailed research and optimization of the color based tiling process,the main components of the tiling machine are designed,including feeding components,loading components,and mould transport and limit component.The prototype is manufactured and tested.The loading deviation is studied,and a method is proposed to eliminate the tiling deviation making use of vibration.Then based on a simplified model,the parameter of the vibration source needed to eliminate the loading deviation has been calculated.When it is in a certain range,vibration can successfully eliminate the vibration..While feeding the upside of mosaic tiles must be identical,a V-shaped track-like turning mechanism that can be integrated in the vibrating feeder has been implemented.The kinematics of turning process is calculated,and the improved vibratory feeder is tested,the rate of turnover successfully and output speed of mosaic is high.A method encoding the image into digit is designed,and automation of mosaic tiling based on PLC is accomplished.At first algorithms to obtain target patter,and verification is performed using MATLAB.Then MX Component is used to send the coded integer data to different PLC.Finally the PLC control the loading parts selectively pick color mosaic accord to the decoded data to finish tiling.
