Background: Current beverage cans crusher machines need high energy due to the forces
involved in the crushing process. Some of these machines used a single force in a horizontal direction
only (in the direction of can’s diameter), while others used two forces, one horizontal and another
in a vertical direction (in the can’s longitudinal direction); the vertical force is applied firstly followed
by the horizontal one. In such machines (when applying one force or two forces), the can
needs a very high compacted force.
Methods: In this invention, which is based on our patent no. KSA4610, 2016, we present a newly designed
machine to crush cans with much less forces than others. The new design applies two forces
in a horizontal direction and a third one is applied in a vertical direction; the horizontal forces are applied
firstly in middle position of the can (in points only) and thus, the can becomes weak and needs
a little vertical force to be pressed to the desired size.
Results: In addition, the machine in our invention uses a renewable source of energy as a power supply
source, i.e. no expenses for operations. The machine consists of multi pistons, two horizontals
and one vertical, solar cell system to operate the machine, pneumatic system, sensor, servo motor,
controller, software, and a wooden structure to contain all the machine parts. The machine is designed
to be used in many places (usually uncontained such kinds of machines), such as in aircraft,
restrooms, offices and even in cars; this invention, in view of that, may limit throwing of beverage
cans on streets or in the garbage.
