The Jig Station
The ‘Jig Station’ is the computer station that determines what roof trusses, wall frames and floor trusses are to be produced. The jig station has work allocated in a set priority by the controller.
The jig station has two functions:-
- Produce Trusses - There are the same details on the FMS screen that are on the manufacturing sheets produced by the detailers.
- Time and Motion Studies - When each truss is set up the user selects the ‘Set Up Complete’ button to stop the timing of the set up production time and when the manufacturing of all the trusses in that run is completed the user selects the ‘Manufacturing Complete’ button to stop the timing of truss production.
The jig setter has enough details to be able to produce and mark each truss. The details shown are job number, truss type and number, size and grade of each member, quantity of trusses, size and positioning of plates, member lengths, truss set out details and overhang details. When the truss first appears on the screen, timing begins. When the sawyer has set up the truss they will select ‘Set up Complete’, this action stops the labour set up timing. When the run of trusses has been produced and the jig setter is ready to set up the next run the jig setter then selects ‘Manufacturing Complete’, this stops the manufacturing timing which was started when set up was completed. The list of trusses will automatically scroll to the next truss and show it on the screen
To ensure correct truss manufacturing, the jig setter has a number of tools available to them:-
- Zoom Mode – the zoom mode allows the user to zoom into a joint and view the truss placement dimensions.
- Layout Mode – to assist in the process of truss marking and pack building the users can also view the roof layout for the job they are making, this will also assist with wailing plate fixing and truss boot placements.
- View Notes – as this is designed to be a paperless system the detailer can create a note for each truss in the job and store it with the truss as it is manufactured. The note can be text, a drawing or a combination of both text and drawings. The user can view the details at any time suitable during the manufacturing process
