SELF RISING FLAG MACHINE

Özet

This paper presents a motorized flag-raising and lowering device that can be used in different settings such as public spaces, governmental buildings, and private residences. The device has a hollow flagpole with a storage compartment and a side exit port, a pulley at the top, and a drive wheel at the bottom. The flag is connected to the motorized assembly by a continuous halyard that runs through the pulley and the drive wheel. A reversible motor is housed in the assembly, which can be activated to lower the flag into the storage compartment and raise it for display. The device offers easy flag maintenance, adjustable speed rate, and reduced twisting of the flag strap. The research aims to solve the problems encountered during official flag assemblies in Malaysian schools, including the absence of students on duty, the flag not reaching the top of the flagpole, and twisting of the flag rope. To address this complex problem, a self-rising flag machine was created using a combination of simple machines such as polycarbonate, PVC, and remote-controlled car motors. The machine is portable, user-friendly, and can be easily controlled by a remote controller, reducing the time taken to prepare the flag during the assembly. Although the self-rising flag machine was initially designed for use in schools, it has the potential to be used in various settings, enhancing aesthetics, and providing convenience and safety features for flag maintenance. However, the machine has a limitation that it cannot be controlled at more than 20 meters from the machine, and the tension of the flag rope should be neither too tight nor too loose. Overall, this research offers a practical solution to the challenges faced during flag-raising ceremonies in different settings.
