A control system for a conveyor system of a machine includes a motor to drive the conveyor system, and a pump operably coupled to the motor. A solenoid actuator actuates the pump. The control system includes operator interfaces to enable an operator to provide inputs indicative of a desired engine speed, and a desired conveyor speed. The control system includes a controller which determines a pump speed based on the desired engine speed, and determines a maximum possible motor speed based on the pump speed and a maximum possible gear ratio between the pump and the motor. The controller determines a desired motor speed based on the desired conveyor speed. The controller determines a solenoid actuation current based on the desired motor speed and the maximum possible motor speed, and supplies the solenoid actuation current to the solenoid actuator to control a speed of the conveyor system.

A transfer device for introducing and/or removing articles to a process device includes a basic frame and a conveying unit, which is supported by the basic frame and transfers or receives articles to or from the process device. The conveying unit is designed to be movably positionable in order for the transfer device to be reversibly advanced up to the process device. The conveying unit includes an output element of a magnetic coupling and is designed for reversibly coupling the transfer device to a corresponding drive element of the magnetic coupling, the drive element being provided on the process device. When the drive element and the output element are coupled to one another, the magnetic coupling effectuates a force transmission from a drive unit of the process device to the conveying unit.

A trolley assembly for overhead track testing is provided. In one example embodiment, a trolley assembly includes an idle roller that rotates about a first axis, a first top roller coupled to a first end of the idle roller via a first trolley upright support, and a second top roller coupled to a second end of the idle roller via a second trolley upright support. The trolley assembly includes a cantilever coupled to the idle roller. The trolley assembly includes a driveshaft coupled to a first end of the cantilever. The trolley assembly includes at least one motor coupled to the drive shaft.

The program directs a computer processor to implement a program that prioritizes a direction of movement of a directional pedestrian mover (DPM) based on predicted pedestrian traffic flow. The program obtains a first predicted pedestrian traffic flow relative to the direction of movement of the DPM, and a second predicted pedestrian traffic flow in a different direction relative to the first predicted pedestrian traffic flow. The program determines that the second predicted pedestrian traffic flow exceeds the first predicted pedestrian traffic flow, and changes the direction of movement of the DPM to accommodate the second predicted pedestrian traffic flow. The program calculates a time for a majority of the first predicted pedestrian traffic flow, and a majority of the second predicted pedestrian traffic flow, to reach at least one access point of the DPM.

A tensioning mechanism for a conveyor system includes a support structure, a first carriage, a second carriage, and a brake mechanism. The first carriage is positioned proximate a first end of the support structure and is supported for movement relative to the support structure. The first carriage includes first rolls for receiving the belt such that movement of the first carriage modifies a tension in the belt. The second carriage is supported for movement relative to the support structure and includes second rolls and at least one return pulley. The second rolls are configured to support a portion of the belt extending between the first carriage and the second carriage. The brake mechanism is positioned proximate a second end of the support structure and includes a brake pulley and a brake selectively retarding rotation of the brake pulley. The brake pulley supports a portion of the belt extending between the brake mechanism and the return pulley.
