Conveyor feeding of lifting table
The Yaskawa lifting table can be equipped with a conveyor system with an upper and lower conveyor so the system both feeds the lifting table with new pallets and empties it for empty pallets.
The conveyor system changes pallets much faster than the operator can perform it, and it eliminates the operator for wasting his time for pallet changes, so it increases the productivity of the sheet cutter line significantly.
The control of the conveyor system is performed by Yaskawa Levanto. The only manual activities are to put new pallets on the conveyor and remove the empty pallets from the lower conveyor.
The length of the conveyor system determines its storage capacity of new pallets. The standard version holds 3 pallets.
Turntable under the vibration table
A turntable can be installed under the vibration table so it can be turned 180º so the Motoman SDA 20 robot can access the vibration from both front and back.
With the Motoman SDA 20 robot installed behind the vibration table, the feeding is performed from the vibration table’s back side. This implies that the feeding of the table also contains a stack turning, which eliminates the required pile-turning in connection with handling of f.ex magazine covers with coatings.
Installing the vibration table on a turntable allows Yaskawa Levanto to feed the vibration table from the front.
The position of the vibration table is controlled from by Yaskawa Levanto’ touch screen.
Automatic stack transport system and air tables
A part of the normal operator job is to collect the vibrated stack on the vibration table and push it to the sheet cutter.
An automatic transport system, which takes the vibrated stack from the vibration table and to the side table of the sheet cutter can be installed. As soon as the vibration process is finished the transport gripper collects the stack at the vibration table and transports it on an air-cushion table to a position on an intermediary storage table. As soon as the operator wants the stack on the side table he asks for it and it is delivered to the sheet cutter’s side table.
This system performs the time-consuming and heavy job of pushing the heavy stack to the sheet cutter so the operator can focus all his time on the central job: cutting stacks.
