Abstract
The multistation switch system comprises position detector for detecting current position of a main shaft, programmable switch device provided for each of the stations for receiving position data formed in accordance with output of the position detector and generating, in response to the position data, one or more on/off signals which are predetermined in correspondence to selected position or positions of the main shaft, and start/stop interlock circuit for setting start and stop timings for starting and stopping a switch output in correspondence to the programmable switch device provided for each station. The programmable switch device for each station outputs the on/off signals between the start and stop timings set by the start/stop interlock circuit in correspondence to each station.
Claims13
A multistation switch system in a control system having plural work stations each performing a series of work by operation of one or more operation means and controlling the operation by said operation means in each station in accordance with position of a main shaft independently for each station, said multistation switch system generating on/off signals for controlling operations in the respective stations in accordance with the position of said main shaft characterized in that said multistation switch system comprises:
- position detection means for detecting current position of said main shaft;
- programmable switch means provided for each of said stations for receiving position data formed in accordance with output of said position detection means and generating, in response to said position data, one or more on/off signals which are predetermined in correspondence to selected position or positions of the main shaft;
- and
- start/stop interlock means for setting start and stop timings for starting and stopping a switch output in correspondence to said programmable switch means provided for each station,
- said programmable switch means for each station outputting the on/off signals between the start and stop timings set by said start/stop interlock means in correspondence to each station.
A multistation switching system for controlling a plurality of work stations comprising the combination of:
- a master device for assuming different positions;
- a position detector for determining the position of the master device;
- a different programmable switch device associated with each of the plurality of work stations and responsive to the position detector for producing output signals therefrom to control operation of the associated station independently of the other stations;
- and
- a common start/stop interlock device for controlling the output signals produced by each of the different programmable switch devices independently of the other programmable switch devices.
