Ream Stacker/Accumulator
The Model 137HS ream stacker/accumulator precisely stacks of U.S. and metric size reams to preset height and ensures smooth product handling and exceptional control including diverting stacks to an accumulation belt when necessary. It is available as a last-in/first-out (LIFO) or a first-in/first-out (FIFO) configuration. If necessary, stacks are diverted to an accumulation belt and automatically fed back in line when production resumes.

• Exceptional control of ream stacking process
• Up to 150 reams per minute can be stacked
• LIFO or FIFO configuration possible
• Logic control to monitor production & to divert stacks to accumulation belt if needed
• Automatic back feeding of accumulated stacks in line
• Smooth product handling due to motor controlled axis

The Model 137HS ream stacker/accumulator is available as a last-in/first-out (LIFO) or a first-in/first-out (FIFO) configuration and provides exceptional control in stacking standard U.S. or metric ream sizes. An accumulator belt ensures that stacked reams can be diverted if production stops and be fed in again once it resumes.
Simple operation with touchscreen interface
A touchscreen simplifies machine operation. The Model 137HS is a self-contained machine with PLC and its open design allows for complete access and easy maintenance.
Stacker system with single or double stacking capability
The belt infeed conveyor is driven by an electric motor. A cam-operated ream pusher carefully moves the reams towards elevator system. The descending elevator stacks reams to preset height. It offers both single and double stacking capability.
Accumulating system and conveyor
Logic controls monitor the line status for accumulating or discharging and automatically transfer ream stacks to accumulator belt when production downstream is interrupted. Accumulator conveyor starts if backlog is detected and automatically feeds stacks back in line when downstream production resumes. An operator warning sounds when accumulator belt is activated.
