Monitoring mechanism for the take-up embroidery supply for the machine is a rope transfer mechanism 1, the drive mechanism (2), embroidered tension mechanism for the rope (3), the ropes return and delivery for driving the rope transfer mechanism (1) (4) and the rope comprises a number of times and transfer mechanism (5). The embroidery tension mechanism for the rope (3) comprises a swing bar (31) movably connected with the shaft pin 30 on the motor side thereof in the sheet. The guiding wheel 34 to the other end of the swinging bar 31 is arranged. On the swing bar 31 and the pin shaft (30) located close to restore the spring 32 is in this arrangement, the other end position of the return spring 32 is fixed on the motor seat. The monitoring mechanism for the rope recovery and transfer 4 comprises an encoder disc 40 on the one side of the rope recovering photo coupler assembly 41, a photo coupler assembly for a rope transmission 42, and the pin shaft (30). The gap region for the light transmission are radially arranged on the encoder disc (40). Recovering the rope assembly photocoupler 41 and photocoupler assembly for passing the rope 42 is arranged on the motor seat, and each of the corresponding and connected to the computer control system in a gap area on the encoder disk (40). Rope recovery and transfer mechanism 5 is disposed on one side of the rope recovery and transfer motor 50, the motor 50, the rope drive wheel (51) for conveying disposed at the end of the output shaft of, and the drive wheels 51 It includes a driven wheel for feeding a rope (52). Tension mechanism for embroidery rope 3, the rope recovery and monitoring mechanisms for the transmission 4, and the rope collection and transmission mechanism due to the cooperation between (5), supplies the upper thread (upper thread) is pulled events during embroidery It can be prevented, and complement can be recovered when the embroidery rope according ever embroidery (complementary embroidering) during, and thus can ensure the quality of the embroidery.
