Product Features

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. 

Precise Case Stacking

The Model 137HS provides full control in stacking of up to 150 reams per minute of standard U.S. or metric ream size.  

Flexibility

The ream stacker/accumulator is available as a last-in/first-out (LIFO) or a first-in/first-out (FIFO) configuration. It offers both single and double stacking capability.

Accumulating System

When production downstream is interrupted, the ream stacker automatically transfers ream stacks to an accumulator belt. The accumulator conveyor starts if backlog is detected and automatically feeds stacks back in line when downstream production resumes. 

Simple Operation

The Model 137HS is a self-contained machine with PLC, a touchscreen simplifies the machine operation, and its open design allows for complete access and easy maintenance.

Compare With

Full control in stacking of up to 150 reams per minute

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.
