Case Packer

Briefing

A case packer accumulates products from a conveyor until the target count (12 per case) is reached, then a pusher loads them into an open case. Once the PACKING_COMPLETE_LS confirms the case is full, CASE_SEAL pulses to seal the case, the count resets, and the machine waits for the next case.

Objectives

• COUNT_SENSOR increments the product counter on each rising edge (while running)
• When count reaches 12 (target), DIVERTER activates to stop new products entering
• PUSHER activates when count is at target AND CASE_READY
• PACKING_COMPLETE_LS triggers CASE_SEAL pulse (500ms), then count resets
• READY_LAMP on while count < target and CASE_READY (ready to accept product)
• STOP_PB resets count and de-energises all outputs

I/O Table

Your program will be tested against:

All test cases run automatically when you submit. Assertions are hidden until you pass.

1. #1READY_LAMP on when running and case ready

   START_PB + CASE_READY -> READY_LAMP

2. #2COUNT_SENSOR pulses increment product count

   Physics counts product pulses and pushes count state

3. #3DIVERTER activates when count reaches target

   12 count pulses -> DIVERTER on

4. #4PACKING_COMPLETE_LS triggers case seal and count reset

   After pushing, LS triggers seal, count resets
