PURPOSE: An automatic binding apparatus of rubber bands is provided to facilitate maintenance and to bind various products to a bundle. CONSTITUTION: An automatic binding apparatus of rubber bands comprises a geared motor(12), a first driving shaft, a first driven shaft(16), a second driven shaft(18), a lever, a third driven shaft(22), a rubber band discharge wheel bar, a tension adjusting device, a lower slide cam, a rack gear, a spur gear, a horizontal bevel gear, upper and lower tong units, a rubber band hanging cam(42), a circular cam, a cutter, and a power cutoff cam(54). The geared motor generates counterclockwise rotation force. The first driving shaft receives driving force generating in the geared motor through a power transmission device to be rotated toward a counterclockwise. The rubber band discharge wheel bar prevents secession of a rubber band(24a) when the rubber band is supplied, and supplies the rubber band wound on a bobbin(24) to a rubber band binding unit. The tension adjusting device supplies the rubber band wound on the bobbin to the rubber band discharge wheel bar in a state where the rubber band maintains a constant tension by receiving through a guide member. The rubber band hanging cam tightly grips one side of the rubber band supplied to the rubber band discharge wheel bar while passing through the lower part of the lower tong unit, and tightly grips the other side of the rubber band to form an amorphous closed loop by the rubber band according to ascending of the rubber band discharge wheel bar.
