5. 5 2-2-1. Basic Mechanism Reversing Reversing When SOL1 is on, the coil will be magnetized and go up. And the touch roller will go down. SOL 1 : ON SOL 1 : OFF

6. 6 LS5: Counts rotation of Reverse Touch Roller (Reversing Pulse) Revering Start: Reverse Touch Roller rotates (LS5 turns on/off) quickly. On On On On On On Off Off Off Off Off Revering completed: Reverse Touch Roller is about to stop. And the interval gets longer (30ms as normal). On On On On On Off Off Off Off 30msec 2-2-2. Basic Mechanism Reversing(2)

7. 7 Off Off Off Off On On On On On 2-2-3. Basic Mechanism Reversing(3) Case Study : Sekkingston in Bergen Trouble : Reversing stops before going around the box (tensioning was too loose) because of the friction of styrene foam. Solution : VR1 This interval can be longer by VR1.

8. 8 2-3. Basic Mechanism Tensioning Tensioning When SOL2 is on, the coil will be magnetized and go up. And the touch roller will go up to contact the Tension Roller. SOL 2 : OFF SOL 2 : ON

9. 9 2-4. Basic Mechanism Feeding (forwarding) Feeding When Power switch is on, SOL3 is on. The coil is already magnetized and the touch roller is released. When SOL3 is off, the touch roller will contact the Feed Roller. SOL 3 : OFFSOL 3 : ON

13. 13 4-1-1. Timers and Volumes T1 (1) T1 timer sets the reversing time (pulse counts) until when tensioning will be cancelled. When a strapping cycle is accidentally initiated without any package on the table, tensioning on slide table can be cancelled by T1 setting. (“Jump Out” or “Loop Ejection”). When strap is reversed too much, tensioning will be cancelled. Ex. T1=0 (30counts) T1=10 (72counts) No tensioning Slide Table Slide table is strapped even without any package. When the tensioning is cancelled, the strap will make a loop around the slide table and will be ejected.

15. 15 4-2. Timers and Volumes T2 (Forward timer) Controls the strap forwarding time Large Arch : T2 needs to be set higher. Small Arch : T2 needs to be set lower. Should be adjusted at the point at which the strap barely reach the stopper at the sealing head (under the slide table). ④ ① ② ③ LS1 detects the large hole. LS2 doesn’t. T2 determines how long the timing plate stays on this position. Too short > Strap won’t reach the Sealing Point. Too long > Strap will hit the stopper so hard that the edge of the strap will be bent.

16. 16 Mechanism Heater volume controls the length of pulse (frequency of 5.7V pulse) supplied to Heater. 5.7V 0 0 Lower Temperature Higher Temperature 4-3. Timers and Volumes Heater

18. 18 Heater Temperature Strapping Temperature drops gradually Normal Operation Continuous High-speed Operation Temperature returns after a cycle And, In a normal (not so fast) operation: Heater temperature return to the original before the next cycle. In a continuous High-speed operation or under cold environment : Heater doesn’t have enough time to return to the original temperature before Just after the sealing process, Heater temperature drops slightly because the heat gets lost by melting the strap. VR3 prevents this drop of temperature by a little longer pulse supply to the Heater from 0 to 1 second. 5.7V Heater Active time after sealing is prolonged. Caution: Heater may be too hot by increasing VR3. 4-5. Timers and Volumes VR3

19. 19 When there is some problem (such as scratch) inside the Arch, reversing might be finished before going around the package. Problem Without VR4, reversing is finished before strapping the package. 4-6-1. Timers and Volumes VR4 (1) On On On On On Off Off Off Off Problem Reversing is finished.

And, VR4 and VR5 can be used when LS5 is broken. In this case, VR4 should be more than 1. (Value does not matter because pulse can not be counted.)
