[0050] Based on the above structure, a working method of an automatic sorting and packaging device for injection molded sole components includes the following steps:

[0051] 1) Initial position: the rotary cylinder 21 rotates so that a set of suction cups 24 is in a horizontal position above the receiving platform 23, and the robot takes the sole component out of the injection molding machine and places it on a set of suction cups 24 on the receiving platform 23;

[0055] 5) A set of suction cups 24 is released, the sole component is placed on the raw material platform body 37, and the piston rod of the lifting cylinder 34 is retracted, driving the raw material platform body 37 with the sole component placed thereon to descend back to the initial position;

[0056] 6) The offset slide cylinder 31 is started, driving the raw material platform 32 to move along the linear slide rail 1 33 toward the three-axis device 4 until the raw material platform 32 is at the end of the offset slide cylinder 31 close to the three-axis device 4;

[0057] 7) The Y-axis linear module 41 and the X-axis linear module 42 are started, driving a set of suction cups 46 to be located directly above the raw material platform body 37;

[0058] 8) The piston rod of the Z-axis lifting cylinder 43 extends, driving the lifting slide 48 to descend, thereby causing the R-axis motor 44 to descend until a set of suction cups 46 is directly above the sole component on the raw material platform body 37;

[0059] 9) A set of suction cups 46 are activated to form negative pressure, which adsorbs the sole components on the raw material platform body 37, and the piston rod of the Z-axis lifting cylinder 43 is retracted, driving the R-axis motor 44 to rise;

[0060] 10) The Y-axis linear module 41 and the X-axis linear module 42 are started, and according to the setting of the control system, a set of suction cups 46 are driven to move the sole component to the corresponding position of the strapping machine 5;

[0061] 11) The R-axis motor 44 drives the support plate 45 to rotate 90°, and the piston rod of the Z-axis lifting cylinder 43 extends, so that a set of suction cups 46 is directly above the material positioning component 6.

[0064] 14) Repeat the above steps 1) to 13) continuously and automatically carry out strapping and unloading of the sole components.

[0065] The robot takes the sole component out of the injection molding machine and places it on the receiving platform. After the suction cup absorbs the product, the rotating cylinder drives the receiving platform to flip 180° to make the product face downward. The lifting cylinder drives the raw material platform to rise to take the material. Then the lifting cylinder descends and the offset cylinder is activated and the lifting cylinder rises again to hold up the product. The three-axis mechanism takes the material here and puts it in a suitable position for the baler. The material is automatically overlapped with the assistance of the positioning block. The left foot material and the right foot material are sorted and placed on two baling platforms respectively. After repeating the entire baling process 10 times, the baler automatically packs. The three-axis mechanism takes out the packaged finished product and discharges it from the blanking chute.

[0066] The invention is an automatic sorting and packaging device for injection molded sole components. It uses a relatively low-cost electric screw three-axis mechanism as a main mechanism to complete a series of processes from left and right foot sorting, packaging machine loading, automatic packaging, and packaging finished product unloading, thereby improving work efficiency while ensuring packaging quality.

[0067] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
