Application: 
A material vending manufacturer was designing a vending machine for supplying tools. A solution was needed to automatically move the gripper assembly to pick and issue tools on command.  The gripper was required to precisely move a maximum 20 Lb load horizontally and vertically across the face of the machine at a moderate speed.

Solution: 
ROLLON designed a 2-axis gantry system using the A55 Uniline actuator in the vertical position to carry the gripper assembly and two A40 Uniline actuators in the horizontal position to support the vertical actuator.  With ROLLON’s actuators having a repeatability of positioning equal to 0.004” (0.1mm), there was no doubt the units would be able to function in the vending machine.  The light load requirement also made it possible to use the smaller size actuators, saving design space in the vending machine.

Application:
In a glass manufacturing plant,  one process required transferring the glass.  A design was needed to accurately position several rows of suction cups along the glass to grab and transfer the glass.  A problem existed in the transfer since it was necessary to pivot and swing the entire gripping assembly and glass from a horizontal postion to a vertical position and placing the glass on a vertical rack.  This pivot action created unknown extra moments and forces on the gripper assembly.

Solution:  
Several ROLLON three-trolley size 75 Uniline actuators were installed as part of the gripper assembly to mount the series of suction cups used to pick and move the glass.  Because of the pivot action taking place during the process, a special modification was needed on the actuators.  ROLLON’s Easy Rail was incorporated into the actuator in place of the standard Compact series rail.  The Easy Rails’ use of bearing balls in its design increased the load and moment capacities of the actuators by appoximately five times, allowing the actuators to handle the unknown loads and moments.

Application:
The US Army was developing a vehicle to transport as many wounded personnel as possible at one time.  They required a solution that would be flexible while capable of handling the necessary weight.  Another concern is the design chosen must be able to support any extra stresses created while the vehicle is moving.

Solution: 
ROLLON’s DE43 telescopic rails were used to mount the stretchers. The rails extended outward during loading and unloading of the wounded and retracted during transportation. This flexibility provided extra space in the vehicle to allow up to 12 stretchers.  The stroke was reduced in the rails to give a higher load capacity and a higher safety factor.  When closed, the load capacity of the rails increased almost 10 times its rating when fully extended, making it possible for the rails to handle the extra forces created during transportation. 

Application: 
A yacht manufacturer was developing a wing station for both sides of the yacht.   The stations allow the pilot to dock the yacht from the side of the ship where a clearer view of the yacht is available.  The stations consist of the controls for steering as well as the platform for the pilot to stand.  When needed, the station would be extended out from the side of the ship and when completed, the station would retract back into the side of the yacht.  A method was needed to move the station as well as support its load.

Solution: 
ROLLON provided a two part solution to support the load and provide the movement.  ROLLON’s DSS Telescopic rails were designed in to help carry the weight of the station while extended out from the yacht.  The rails were nickel plated and stainless bearing balls were used to provide protection against the environment.  The ROLLON Uniline size 55 actuator was also used in the design to move the platform. Use of the medium sized actuator was possible since all the weight of the station would be supported by other rails, preventing any load from being carried by the actuator.

Application:
A customer in the mobility industry was designing a new power transfer seat which allows an individual to transfer from a wheelchair to a driver’s or passenger’s seat in a vehicle.  They were searching for a linear telescopic system which can hold a total of 9000 Lbs, withstand crash forces while in the driving or closed position while at the same time requiring little actuation force and low maintenance.

Solution:
ROLLON supplied ASN43 Telescopic rails to support the transfer seat.  These rails provided the necessary stroke the customer was looking for.  Since the stroke in one direction is half the length of the rail,  the load capacity is very high while allowing almost zero deflection.  When in the closed position, the load capacity greatly increases, making the rails capable of withstanding the crash forces.  Because of its low friction, minimal force is required to move the rails.

Application:  
An amusement park attraction was designed to include a wheelchair accessible platform.  The platform is to move the wheelchair-bound guest toward the vehicle to load t6he person onto the ride.  A maximum load is 500 Lbs and a total extension of 56” was specified.  A critical requirement was there could be no deflection by the platform since the platform had to mount flush against the floor of the ride so the wheelchair can roll smoothly onto the ride without getting hung up.

Solution:

Although ROLLON’s DE43 Telescopic rail easily carried the load at the specified stroke, slight deflection was encountered at the end of the platform.  This forced ROLLON to come up with a new and better solution.  A DE63 Telescopic rail was designed for the project.  This larger rail provided not only more load capacity along with its customary smooth movement, but increased the stiffness in the extension of the rail.  This extra stiffness eliminated the deflection of the platform.
