Piece 902, the position mark piece are located at immediately below shuttle box 7, and in the end height and position sensing of the position mark piece
Device is corresponding, so that bobbin case, when more changing device is translated along horizontal guide rail, the end of position mark piece can be by position sensor
Optocoupler slot, so that position sensor be allowed to identify.
The setting of position mark piece can be there are two types of mode, the first is that a position is respectively arranged immediately below each shuttle box 7
Marker slip, second is the cabinet setting for being spaced quantity if they are the same.When using first way, control panel and control host can be right
The position mark piece that position sensor passes through when bobbin case more changing device is translated along horizontal guide rail is counted, and bobbin case is combined to replace
The translation direction of device, control bobbin case more changing device rest on 7 lower section of shuttle box for needing to carry out bobbin case replacement.Using second
When mode, since the shuttle box 7 that each bobbin case more changing device is responsible for adjacent identical quantity forms 7 groups of shuttle box of bobbin case more
It changes jobs, therefore a position mark piece, control panel can be set immediately below 7 groups of each shuttle box of first shuttle box 7
With control host then need to bobbin case more changing device along horizontal guide rail translate when position sensor pass through position mark piece into
Row counts, and combines bobbin case more changing device translation direction, determines that bobbin case more changing device is located at 7 groups of regions of corresponding shuttle box,
The data such as the turnning circle according to third servo motor 502 calculate the specific location for determining bobbin case more changing device, and control bobbin case is more
Changing device rests on 7 lower section of shuttle box for needing to carry out bobbin case replacement.
Control panel uses the circuit control panel based on single-chip microcontroller or PLC, can be realized for position sensor, the first servo
Motor 314, the second servo motor 402, third servo motor 502, the coordinated control of electromagnetism push rod and feedback signal processing.
Control panel configures model KYL-485 wireless communication module, realizes the wireless telecommunications with control host, and control host is enable to assist
Each bobbin case more changing device is made in regulation.The circuit connection structure of control panel belongs to the common knowledge of mechanical control circuit technical field,
So it will not be repeated.Host is controlled as host computer, PC can be used or industrial personal computer is realized, belong to mechanical control circuit technical field
Common knowledge also repeats no more.
