Release Unit D30 Bar T1

Efficient picking made easy: Compact Release Unit D30 makes it possible to automatically load and unload flow racks. Customised shooters that move small load carriers from station to station help to reduce production costs. Release Unit D30 features a robust pivoting Bar that holds transport crates in place on the roller conveyor. The system’s locking mechanism is automatically opened when there is side-on contact between an Actuator Ramp and Actuator Roller and the shooter and workstation are correctly aligned. The Spring-Loaded Reset Device ensures the Bar travels back to its original position as soon as the transport rack moves away. This type of shooter solution supports the selective release of individual conveyor lines, thus enabling the precise operation of picking systems with feed and return lines. Two Bars are available for different loads. Release Unit D30 Bar T2 features smooth-running ball and needle bearings, meaning lower actuation forces are required than with Release Unit D30 Bar T1. The Release Unit remains easy to actuate, even when the Bar is exposed to axial pressure from heavy containers. This results in added operational reliability. Bar T1 is supplied with fastening elements for connecting it to a Profile 6 D30. To install Bar T2, the relevant Fastening Set for either Profile 6 D30 or Profile 6 30x30 must be ordered. Actuator Ramps are available in two installation depths to suit different roller conveyors (38 and 61 mm). This ensures that even conveyor lines that protrude can be reliably actuated.

How Release Unit D30 works: Stable Bars hold the load in place (e.g. transport boxes). When the shooter pulls alongside, its Actuator Roller rolls up and over the Ramp on the workstation. The Actuator Roller is fixed to a spring-mounted strut - the roller strut - that follows the contour of the Ramp and is thus pushed up and to the side. This causes the Bars that are fastened to both the roller strut and the upper profile to pivot to the side, thereby ensuring that the load is only released when the roller conveyor is correctly aligned.

When the shooter approaches, the Roller strut moves closer to the roller conveyor as the Ramp pushes it up and to the side. This movement forces the Bars to pivot to the side. When the shooter is moved away, the pressure on the ball-bearing mounted Actuator Roller drops and the Spring-loaded Reset Device pulls the roller strut back down to the starting position. The Bars can be installed so that they open to the right or left as appropriate to the transport rack’s direction of travel.

L: Total clearance a: Recommended minimum clearance = 113 mm b: min. 91 mm l1 = L-a-b-6 mm (Profile 6 D30 for the Roller strut) l2 = b-28.5 mm (Profile 6 D30 for the stop) A Release Unit D30 Actuator Roller operates at least two Bars at once and can operate more, if necessary. Depending on the width of the load, a second roller conveyor can be secured simply by adding an additional Bar.

The shooter is released when the Actuator Roller runs over the Actuator Ramp.

The Release Unit can perform the same function even on protruding roller conveyors.

Note: Profile 6 D30 (0.0.616.46) or Profile 6 30x30 (0.0.419.06) must be used to fasten the Bar and the Actuator Ramp.
