By being movably arranged on the installation rod 530, the first opening component 521 and the second opening component 522 of the opening device 520 extend into the fabric and move away from each other to open the fabric. The size data of the fabric can be calculated according to the movement distance of the first opening component 521 and the second opening component 522, and the opening device 520 can send the size data to the hemming machine 100, so that the hemming machine 100 can process the fabric according to the size data.

[0067] Please refer to Figure 2 In some embodiments, the first opening component 521 comprises a first opening member 5211, a first driving device 5212 and a second driving device 5213, and the second opening component 522 comprises a second opening member 5221, a third driving device 5222 and a fourth driving device 5223.

[0068] Specifically, the first opening member 5211 and the second opening member 5221 are used to open the fabric so as to measure the size of the fabric. It can be understood that the width c of the first opening component 521 and the second opening component 522 in the foregoing embodiments is the width of the first opening member 5211 and the second opening member 5221.

The second distraction assembly 522 can control the second distraction piece 5221 to move along the first direction and the second direction by setting the third drive 5222 and the fourth drive 5223. The first distraction piece 5211 and the second distraction piece 5221 can cooperate with each other to measure the size data of the cloth.

[0072] Please refer to Figure 3 In some embodiments, the feeding device 300 includes a tray rack 310, a conveyor 320, and an empty tray rack 330.

[0073] Specifically, the tray rack 310 is installed on the frame 200, and the tray rack 310 is used to place a tray, and the tray is used to carry cloth. The conveyor 320 is installed on the frame 200, and the conveyor 320 can transport the tray along the first direction on the frame 200, that is, the conveyor 320 can transport the tray carrying the cloth to the acquisition device 500, so that the acquisition device 500 can acquire the cloth. The empty tray rack 330 is located on the frame 200 in the first direction of the tray rack 310, and the acquisition device 500 is located between the empty tray rack 330 and the tray rack 310. When the acquisition device 500 has grasped all the cloth in the tray, the conveyor 320 can transport the empty tray to the empty tray rack 330 for storage.

[0074] Further, the first sensor can be arranged on the acquisition device 500, and the first sensor is configured to detect whether the tray is present on the transport device 320. For example, the first sensor can be a camera, and the first sensor is arranged towards the tray rack 310. When the transport device 320 moves to the acquisition device 500, the first sensor can acquire image information of the transport device 320. According to the image information, it can be determined whether the tray is present on the transport device 320. When the tray is not present on the transport device 320, the transport device 320 is controlled to move to the tray rack 310 to acquire the tray carrying the cloth. When the tray is not present in the tray rack 310, an alarm is generated to remind the staff to supplement the tray carrying the cloth. It can be understood that the tray carrying the cloth can be supplemented automatically by the AGV robot. The automatic control of the AGV robot is a prior art, and will not be described here.

[0075] When the tray is present on the transport device 320, the transport device 320 transports the tray to the acquisition device 500. The second sensor can also be arranged on the acquisition device 500. The second sensor is arranged on the grabbing device 510, and the second sensor is configured to detect whether the cloth is present in the tray. When the cloth is present in the tray, the second sensor collides with the cloth to control the grabbing device 510 to grab the cloth, so that the opening device 520 can measure the size data of the cloth, and the suit device 400 can transport the cloth to the hemming machine 100. The hemming machine 100 can process the cloth according to the size data. When the second sensor collides with the tray, it can be determined that there is no cloth in the tray. When there is no cloth in the tray, the grabbing device 510 and the opening device 520 in the acquisition device 500 can move to one end of the mounting rod 530 to avoid blocking the transport device 320 to transport the tray. The transport device 320 can transport the empty tray to the empty tray rack 330 along the first direction. After the transport device 320 lowers the tray, the transport device 320 moves to the tray rack 310 to transport other trays carrying the cloth.

[0076] Optionally, the second sensor can also be configured to detect the edge position of the cloth. When the acquisition device 500 moves to the middle position of the mounting rod 530, the second sensor can identify the edge position of the cloth on the tray and confirm the edge position of the uppermost cloth. According to the edge position of the uppermost cloth identified by the second sensor, the grabbing device 510 can be controlled to move to the edge position of the uppermost cloth to grab the uppermost cloth, so as to prevent the grabbing device 510 from grabbing the lower cloth.

[0077] In some embodiments, when the cloth is placed on the tray, the cloth can partially extend out of the tray, or the tray is provided with a notch, the second sensor can also be a photoelectric sensor, the second sensor is arranged beside the tray or at the notch of the tray, when the tray is provided with the cloth, the second sensor can receive the reflected light signal, when the tray is not provided with the cloth, the second sensor cannot receive the reflected light signal, so as to determine whether the cloth exists on the tray according to the light signal.

[0078] In this way, by arranging the tray rack 310, the tray carrying the cloth can be placed, by arranging the transporter 320, the tray carrying the cloth can be transported to the acquisition device 500, so that the acquisition device 500 can acquire the cloth, when the tray is not provided with the cloth, the transporter 320 can transport the empty tray to the empty tray rack 330 for storage, waiting for the staff to take away the empty tray.

[0079] In some embodiments, the number of tray racks 310 can be multiple, and the multiple tray racks 310 are arranged along the first direction, for example, please refer to Figure 3 The number of tray racks 310 is three, the three tray racks 310 are arranged along the first direction, and the multiple tray racks 310 are respectively placed with the tray carrying the cloth, according to the distance between the multiple tray racks 310 and the acquisition device 500, the transporter 320 can transport the tray on the tray rack 310 in turn from near to far, that is, the transporter 320 can transport the tray carrying the cloth on the tray rack 310 away from the first direction in turn, in this way, by arranging multiple tray racks 310, multiple trays carrying cloth can be stored, the transporter 320 transports the tray on the tray rack 310 close to the acquisition device 500 to the acquisition device 500, so that the acquisition device 500 can acquire the cloth, when the tray is not provided with the cloth, the transporter 320 transports the empty tray to the empty tray rack 330 for storage, and then acquires the tray on the next tray rack 310, so as to continuously provide the acquisition device 500 with the cloth.

[0080] Please refer to Figure 3 In some embodiments, the tray rack 310 and the empty tray rack 330 are provided with a turnover plate 340, the turnover plate 340 is used to carry the tray, when the tray abuts against the turnover plate 340 along the first direction, the turnover plate 340 can be turned over, so that the tray can continue to move along the first direction.

[0081] Specifically, when the transporter 320 transports the tray to above the turnover plate 340, the transporter 320 releases the tray, the tray falls on the turnover plate 340, the turnover plate 340 can carry the tray, that is, the turnover plate 340 can be turned over in one direction along the first direction.

[0082] Thus, by setting the turnover plate 340 on the tray rack 310 and the empty tray rack 330, in the case that the conveyor 320 fixes the tray to move along the first direction, the conveyor 320 can push the turnover plate 340 to turn over, avoiding the turnover plate 340 from blocking the movement of the conveyor 320, so that the tray can be transported to the empty tray rack 330 for storage, and in the case that the conveyor 320 releases the tray, the turnover plate 340 can carry the tray, avoiding the tray from falling.

[0083] Please refer to Figure 1 and Figure 2 In some embodiments, the acquisition device 500 can be movably arranged on the frame 200, and the acquisition device 500 can move along the second direction on the frame 200. In the case that the conveyor 320 transports the empty tray to the empty tray rack 330, the acquisition device 500 can move along the second direction to push the empty tray, so that the empty tray is pushed to one side of the empty tray rack 330 for storage, that is, in the case that there is no cloth in the tray on the conveyor 320, the grabbing device 510 and the opening device 520 move to one end of the mounting rod 530, the conveyor 320 transports the tray to the empty tray rack 330 and releases the tray, the acquisition device 500 moves along the second direction to push the tray to one side of the empty tray rack 330, avoiding the tray from affecting the movement of the conveyor 320 to the tray rack 310, in the case that the acquisition device 500 pushes the tray, the conveyor 320 moves away from the first direction to the tray rack 310 to transport the tray on which the cloth is carried, the acquisition device 500 moves to the middle position of the mounting rod 530, so as to continue to acquire the cloth transported by the conveyor 320.
