[0002] The automatic bobbin case changing, thread removing and winding assembly system is capable of changing bobbin cases at several preset workstations by configuring a bobbin case changing device. The disassembled bobbin cases and spare bobbin cases are placed on a rotating storage tray. When the spare bobbin cases on the bobbin case storage section are used up, a series of automated operations including bobbin thread removing, bobbin winding, bobbin case winding, bobbin and bobbin case assembly, thread jamming and thread breaking are performed on the bobbin and bobbin case with insufficient thread on the bobbin case storage section, thereby realizing fully automated replacement and thread removing of the bobbin thread of the embroidery machine.

[0003] However, in the existing assembly system operation, the bobbin case changing device is constantly moving on the guide rail. Due to the heavy weight of the bobbin case changing device itself and the vibration generated during long-term operation, it is easy to resonate with the guide rail, causing the bobbin case changing device to tear the guide rail off, resulting in personal injury and economic losses.

[0025] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described herein.

[0026] like Figure 1 FIG. 1 illustrates an automatic bobbin case changing system with a buffer device according to an embodiment of the present application. The automatic bobbin case changing system includes a guide rail 1 and a bobbin case changing device 2. A buffer device 3 is disposed between the guide rail 1 and the bobbin case changing device 2. The buffer device 3 includes a mounting seat 31, a roller assembly 32, and a spring 33. The mounting seat 31 includes a mounting groove 311 and a buffer groove 312. The roller assembly 32 is disposed in the mounting groove 311 and abuts against the guide rail 1. The spring 33 is disposed in the buffer groove 312 to abut against the bobbin case changing device 2.

[0027] Preferably, two upper and lower buffer grooves 312 are provided on the mounting seat 31 , and the two springs 33 are respectively disposed in the buffer grooves 312 .

[0028] Specifically, the roller assembly 32 includes a roller 321, a shaft 322, and a stopper 323. The roller 321 is transversely disposed within the mounting slot 311, the shaft 322 is longitudinally disposed within the mounting slot 311 and extends through the roller 321, and the stopper 323 is disposed on both sides of the roller 321 and is located between the shaft 322 and the guide rail 1. In particular, the roller 321 is partially exposed from the mounting slot 311 to abut against the guide rail 1. This arrangement allows the roller 321 to rotate about the shaft 322, allowing the bobbin case changing device 2 to smoothly move on the guide rail 1. The stopper 323 effectively prevents the shaft 322 and roller 321 from falling out of the mounting slot 311.

[0029] More specifically, the bobbin case replacing device 2 includes a bobbin case grabbing mechanism 21, a rotary material storage mechanism 22, and a translation drive mechanism 23. The bobbin case grabbing mechanism 21 and the rotary material storage mechanism 22 are mounted on the translation drive mechanism 23, which is slidably connected to the guide rail 1. It should be understood that the buffer device 3 is fixed to the translation drive mechanism 23.

[0030] Specifically, the bobbin case changing device 2 further includes a guide rail power transmission mechanism 4, which includes a conductive bar 41 and a power transmission device 42. The conductive bar 41 is disposed on the guide rail 1 and extends parallel to the guide rail 1. The bobbin case changing device 2 is electrically connected to the conductive bar 41 via the power transmission device 42. It should be understood that the conductive bar 41 is connected to an external power source and energized. When the power transmission device 42 moves relative to the conductive bar 41, it can supply power to the bobbin case grasping mechanism 21, the rotating material storage mechanism 22, and the translation drive mechanism 23.

[0031] In summary, the present application provides a guide rail power transmission mechanism for an automatic bobbin case changing system, which reduces the amplitude and frequency of vibration of the bobbin case changing device 2 during operation by arranging the buffer device 3 between the bobbin case changing device 2 and the guide rail 1, avoids resonance, effectively improves the working stability of the bobbin case changing device 2, and avoids personal injury and economic losses.
