3.4.3 Pallets with damaged bags关于袋子破裂的托盘
If the bag is punctured and thus without vacuum, the operator will not add the cardboard top piece. The strapping belt unit will detect with a color sensor if the cardboard top piece is present or not. If not, the strapping belt (and wrapping unit) will skip the pallet.
The forklift driver will see the pallet is not strapped (and wrapped) and will bring the pallet to the (re)packing area instead of the warehouse. The forklift driver will also get a visual warning. The pallet will not be weighed on the output buffer conveyor.
如果袋子破裂,没有真空,操作员不会覆盖顶部纸板。打包机会通过一个颜色传感器检测是否有顶部纸板。如果没有,打包机(以及缠绕包装机)会跳过此托盘。
叉车司机看到托盘没有被打包(缠绕包装)会把托盘重新放入到包装区域,而不是仓库。叉车司机也会得到一个视觉警告。托盘不会在出口缓冲区被称重。

3.5 Belt Strapping Unit捆扎打包机
3.5.1 Build-up布局
The belt strapping unit consists of an automatic single belt strapper. The strapper straps one belt at the time around the pallet. The pallet is rotated multiple times to apply the different straps. Rotating table is under the strapping unit.The unit has 2 pallet detection sensors for the 2 belt positions. The typical length of the installation is 2000 [mm].Belt specifications are mentioned in 1.4.The strapping head is mounted on a movable (up-down) platform. This platform compresses the pallet before strapping. This guarantees the straps do not come loose when the pallets are placed on to each other in the warehouse. The compressing pressure is adjustable between 200 and 600 kg.
The strap tension is adjustable between 80 and 900 [N].
The strap is sealed by a high strength friction-weld seal.
打包装置包含一个自动单个打包机。打包机在托盘上打一道。托盘旋转数次以实现不同的打包。旋转台在打包机下方。本工位有两个托盘检测传感器。通常的安装长度是2000mm。带子的规格在1.4提及。打包头在一个可移动(上-下)平台上。此平台在打包前会先压缩托盘。这使得托盘在仓库互相叠放时打包带不会变松。压缩压力在200-600kg。
