3 Detail unit description详细分项描述
3.1 Supply unit (SU)供应区
A forklift is used to supply the pallets to the packing unit. Pallets are placed on this position. General specifications are listed in paragraph 2.4.
叉车供货(托盘)。托盘放置在此位置。具体参数描述见2.4段。

Additions to the standard conveyor are
• Protection fork lift
• System to guide/place the pallet in the middle of the rollers. Need a safety support to avoid the truck is damaging the conveyor while loading or unloading.
除标准输送线外还有:
叉车保护 
托盘引导对中装置。需要一个防撞安全支撑。

When the automation detects a new pallet is supplied to the supply unit, it will wait for 10 [s]before transferring the pallet to the next buffer unit. This gives the forklift driver the time to safely supply the pallet to the supply unit.
The supply unit will indicate to the fork lift driver how full the input buffer is (e.g. light column indicating how many buffer positions are filled).
当系统检测到一个新的托盘放置到供应位时,在把托盘输送到下一个缓冲位之前会先等待10秒。这给了叉车司机安全放置托盘的时间。
供应区会提示叉车司机输入缓冲区的装载状态(例如灯柱提示有多少缓冲区是满的)

3.2 Input buffer (IB)输入缓冲区(IB)   
The buffer units are standard chain driven conveyors as described in 2.4.Each buffer conveyor has a pallet detection system (e.g. sender-receiver with reflector). The pallet is transported to the next position if the next position is free. The motor turns until the pallet is not detected anymore and the motor runs for another 2 seconds (see paragraph 2.4.4).
When the previous buffer position tries to transfer a pallet, the local buffer position also starts to rotate to assure a smooth transfer between the two positions.
The pallet is transferred from the last buffer conveyor to the Vacuum-Welding unit after confirmation by operator–see 3.3.
