In the shoe supply apparatus according to the prior art having such an operation, the following problems occur due to the structural limitations.

First, for a 12 grade supplied to the shoe mechanical tilt because suit the method has a structure for 12 grade supplied Sugar free to be dropped, gajigi a structure which can not be rotated to the nature of curvature of the chute in order to implement this, substantially large Space is also required, and a total of 24 part feeders are required for each of 12 upper and lower shoes, making it practically impossible to apply.

Second, since the mechanical inclined chute has a high possibility of buried foreign matter such as fine chips on the shoe, quality problems may occur when assembling the shoe.

Third, the internal space of the mechanical inclined chute can be expanded due to wear of the mechanical inclined chute during long-term use, which may cause the shoe to jam.

Fourth, regular cleaning and maintenance is necessary due to the jamming of the linear feeder.

Fifth, the cost can be very high because stainless steel (SUS) must be applied to prevent magnetization and special surface treatment must be performed when manufacturing the mechanically inclined chute.

Sixth, due to structural limitations, the time for supplying one shoe may be excessively delayed, for example, about 20 seconds, for example, in grade 12 management of the shoe, which may impede productivity.
