Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-5 The present invention will be further illustrated by specific embodiments.

[0027] like Figure 1-5 As shown, a garment hanger gripping device for folding work clothes includes:

[0028] The main frame 9 is connected to the robotic arm;

[0029] A clamping mechanism installed on the main frame 9 is used to clamp folding hangers;

[0030] 1. Hanger hook base; 5. Hanger hook for hanging folding hangers.

[0031] The clamping mechanism includes a clamping telescopic cylinder 13, the cylinder of which is hinged to the main frame 9.

[0032] The aforementioned clamping mechanism also includes a linkage assembly consisting of a pair of hanger extension swing arms 3 and a linkage rod 10.

[0033] One of the hanger extension swing rods 3 is configured as a V-shaped drive linkage, and its apex side is rotatably connected to the main frame 9. One end of it is rotatably connected to the piston rod of the clamping telescopic cylinder 13 and is movably connected to another hanger extension swing rod 3 as a driven rod through the linkage rod 10. The other end of it is used to cooperate with the hanger extension swing rod 3 as a driven rod to clamp the folding hanger.

[0034] The garment hanger gripper device for folding work clothes also includes a hanger unloading push rod 4 and an unloading telescopic cylinder 12. One end of the hanger unloading push rod 4 is rotatably connected to the main frame 9, and the other end of the hanger unloading push rod 4 is equipped with a top rod for triggering the hanger wing locking rod 7 of the folding hanger. The cylinder of the unloading telescopic cylinder 12 is hinged to the main frame 9, and the piston rod of the unloading telescopic cylinder 12 is hinged to the hanger unloading push rod 4.

[0035] The garment hanger gripper device for folding work clothes also includes a hanger hook locking rod 2 and a hook locking telescopic cylinder 11. The cylinder of the hook locking telescopic cylinder 11 is hinged to the main frame 9. The piston rod of the hook locking telescopic cylinder 11 is rotatably connected to the hanger hook locking rod 2. One end of the hanger hook locking rod 2 is rotatably connected to the main frame 9. The other end of the hanger hook locking rod 2 serves as a locking end and presses the hanger hook 5 onto the hanger hook seat 1 when it is necessary to lock the folding hanger.

[0036] The main frame 9 is fixedly connected to a connector 14 for connecting the actuator of an industrial robot.

[0037] The aforementioned hanger hook seat 1 has a positioning structure that supports and cooperates with the hanger hook 5. Such positioning structure can be a positioning groove, a positioning surface, or other positioning structures, which are not limited here.

[0038] The locking end of the aforementioned hanger hook locking rod 2 is designed with a C-shaped groove structure for easy positioning, and it abuts against the hanger hook 5 and engages with the hanger hook 5 when it is necessary to lock the folded hanger.

[0039] The aforementioned hanger hook 1 is centrally located between the two hanger extension rods 3.

[0040] In this embodiment, the hook-lock telescopic cylinder 11, the unloading telescopic cylinder 12, and the clamping telescopic cylinder 13 can be electric cylinders or pneumatic cylinders, or other linear drive mechanisms, which are not limited here.

[0041] like Figure 2 As shown, the hanger hook 5 of the folding hanger is hung on the hanger hook base 1, and the hanger hook locking rod 2 rotates to the locked position under the drive of the hook lock telescopic cylinder 11, as shown. Figure 3 As shown, the locking end of the hanger hook locking rod 2 presses the hanger hook 5 of the folding hanger onto the hanger hook seat 1, forming a clamping and locking function to prevent the folding hanger from swinging back and forth.

[0042] Then, the piston rod of the clamping telescopic cylinder 13 extends, driving the V-shaped hanger extension swing rod 3 to rotate inward. Simultaneously, the V-shaped hanger extension swing rod 3, via the linkage rod 10, drives another hanger extension swing rod 3 to rotate inward, thus enabling both hanger extension swing rods 3 to rotate inward simultaneously until they clamp the folding hanger, causing the two hanger extension swing rods 3 to respectively abut against the two hanger wings 8 distributed on the left and right sides of the folding hanger. Figure 3 This is the state shown, thus preventing the folding hanger from swinging left and right.

[0043] like Figure 4 As shown, when the clothes need to be unloaded from the folding hanger, the hanger extension lever 3 rotates outward at the same time to clear the swing trajectory of the left and right swing feet of the folding hanger. The hanger unloading push rod 4 presses down the hanger wing locking rod 7, causing the two hanger wings 8 on the left and right to retract inward, thereby detaching the clothes from the folding hanger.

[0044] like Figure 5 As shown, the folding hanger in the unloaded state needs to be reopened. The two hanger extension rods 3 rotate inward at the same time, causing the left and right hanger wings 8 of the folding hanger to rotate outward at the same time to extend.

[0045] When the conveyor line is retracted, the hanger unloading push rod 4 returns to its original position, and the hanger extension swing rod 3 and the hanger hook locking rod 2 simultaneously unlock, completing the unloading of the folded hanger and restoring it to its original state. Figure 1 The initial state is shown.

[0046] The above are preferred embodiments of the present invention. Those skilled in the art can make various modifications or improvements based on these embodiments. Without departing from the overall concept of the present invention, such modifications or improvements should fall within the scope of protection claimed by the present invention.
