The working principle and the using method of the invention are as follows:

according to the invention, an operator only needs to sequentially place shoes to be nailed on the heel clamp 2 rotated to the position at the shoe placing station 01, the material rotating table 11 rotates to sequentially send the shoes to the nailing station 02, the detection station 03 and the blanking station 04, the nailing mechanism 3 automatically places the shoes nails on the nail placing seat 41, and the nailing mechanism 4 is matched with the nail placing seat 41 to drive the shoes into shoe heels of the shoes on the corresponding heel clamp 2. The detection mechanism 5 detects whether the nailed shoes are qualified in nailing or not, and feeds back the result to the material distributing mechanism 7; the blanking mechanism 6 takes down the shoes which finish nailing on the corresponding heel clamp 2 from the heel clamp 2, and the material distributing mechanism 7 sorts and discharges the shoes according to the feedback result of the detecting mechanism 5.

The complete heel nailing process when a shoe sequentially passes through the shoe placing station 01, the nailing station 02, the detection station 03 and the blanking station 04 under the driving of the material rotating table 11 is as follows:

putting shoes:the toe cap is abutted against the V-shaped clamp 22, the V-shaped clamp 22 is pushed towards the direction close to the support plate 223, the heel is placed between the U-shaped clamp 21 and the V-shaped clamp 22, then the pushing force of the V-shaped clamp 22 is removed, the V-shaped clamp 22 is driven to move towards the direction close to the U-shaped clamp 21 under the pushing force of the abutting spring 225, and accordingly the heel is pushed into the U-shaped clamp 21 from the leading-in arc plate 233 until the rear end of the heel abuts against the rear end of the U-shaped clamp 21, and the V-shaped clamp 22 is matched under the clamping action of the side clamping plates 23 to fix shoes. If the shoe has a higher boot leg, the corresponding mini fan 26 is started, the side edges of the boot leg are sucked and fixed from the two sides of the boot leg by utilizing the edge sucking plates 25 at the two sides, and the boot leg is separated under the suction action at the two sides, so that the shoe opening is opened. If the shoe does not have a bootleg, the strut assembly 24 may be deactivated.

And (3) nailing:the nails are orderly arranged on the upper nail channel 33 by using the vibration tray 32, the upper nail arm 35 rotates to the position that the electromagnetic suction head 36 at the end part of the upper nail arm is close to the outlet of the upper nail channel 33 to suck one nail, and then the upper nail arm 35 rotates to the position that the electromagnetic suction head 36 is close to the nail placing seat 41 to place the nail into the nail placing hole 411 which is close to the nail placing seat 41.

If the pressure change sensed by the pressure sensor 55 does not exceed the set range, it is determined that the heel nailing of the shoe is acceptable. If the pressure sensor 55 senses that the pressure change exceeds the set range, it indicates that the detecting piece 53 receives the resistance of the protruding portion of the stud, and the heel nailing of the shoe is failed. The pressure sensor 55 feeds back the corresponding detection result to the distributing mechanism 7, and when the shoe rotates to the blanking station 04, the distributing mechanism 7 distributes the shoe according to the feedback result.

And (3) blanking:when the material rotating table 11 rotates to the state that one of the relief grooves 111 corresponds to and is communicated with the accommodating groove 13, the shoe ejecting cylinder 62 drives the shoe ejecting seat 61 to vertically move upwards, the shoe ejecting seat 61 ejects the shoe fixed by the corresponding heel clamp 2 from the heel clamp 2 through the relief groove 111 after being sent out from the accommodating groove 13, the taking of the shoe is completed, and the shoe is conveniently taken away by the follow-up material distributing mechanism 7.

And (3) material separation:the distributing motor 721 drives the distributing arm 72 to rotate to be close to the shoes at the blanking station 04, the pneumatic clamping jaw 722 takes away the shoes ejected by the blanking mechanism 6, the distributing motor 721 drives the distributing arm 72 to rotate to be close to the finished product guide channel 74 or the defective product guide channel 75 according to the detection result fed back by the pressure sensor 55 in the detection mechanism 5, and the taken-out shoes are placed on the finished product guide channel 74 or the defective product guide channel 75, so that the distribution treatment of the shoes is realized.
