Abstract
A modular card production safety interlock system limits disruption of a modular card production system by limiting operational disturbances to a desired system module and only its neighboring system modules upon opening the hood of the desired system module.
Claims19
An interlock system, comprising:
- a protective cover associated with a material processing function module;
- a power transmission device integral solely with the function module;
- and
- a safety interlock circuit, wherein opening the protective cover disables the power transmission device to activate the safety interlock circuit causing the function module and solely adjacent function modules to stop processing material passing through the respective function modules.
1 more element
An interlock system, comprising:
- accessing means for controlling manual access into a material processing function module;
- means for supplying power solely to the function module and at least one adjacent module;
- and
- interlocking means for disabling the means for supplying power and causing the function module and solely any adjacent function modules to stop processing material passing through the respective function modules in response to the manual access into the function module via the accessing means.
1 more element
A method of interlocking a plurality of modular material processing system function modules, the method comprising the steps of:
- providing a modular material processing system having a plurality of function modules, wherein each module has an access cover, a plurality of interlock switches, and a power transmission device integrated therein;
- and
- configuring the plurality of function modules such that opening a single module access cover operates to disable the respective module power transmission device and deactivate hazard related circuits associated with the respective module and solely any adjacent modules.
A modular material processing system interlock system, comprising a plurality of material processing function modules, wherein each function module comprises:
- an access cover;
- a power transmission device;
- and
- a plurality of interlock switches configured such that opening a function module access cover operates predetermined interlock switches to disable the module power transmission device and deactivate hazard related circuits associated with the module and solely any adjacent function modules.
