The underframe HM 140 is predominantly used with straight deposit conveyors. Moreover, it is chosen with larger angled conveyors, when a closed underframe is not feasible due to the conveyor size.
In this case, it is used for a positively angled conveyor of type PL-HM 140 in a special version. The conveyor is integrated into the safety enclosure of an injection moulding machine. The enclosure is closed during operation and the conveyor is in a horizontal position. A sensor controls the position before the automatic operation starts and the robot begins to put down parts on the belt. Therefore the conveyor is not equipped with transporting cleats. In case of a tool change, the straight part of the conveyor inside the safety enclosure is slewed down in order to make way for the operator.
The slewable part is supported by two gas pressure springs, thus it can be easily continuously adjusted in an angle between 0° and 60°.
The single supports are braced in a longitudinal and diagonal direction and are equipped with floor fasteners - for highest stability.
