The A spline shaft sleeve 45 is rotatably mounted on the cloth stacking bracket, and the B assembly shaft section 412 is slidably assembled in the A spline shaft sleeve 45. Since the A cloth piece 01 and the B cloth piece 02 need to be adjusted to move during the sewing process, the flip bracket 40 is adjusted to move along the A direction through the A movement adjustment cylinder 47 to meet the needs of the sewing process.Since the cloth pieces A 01 and B 02 need to be unfolded after sewing for subsequent further processing, in the present invention, the A2 adjustment motor 44 is used to drive the adjustment rod to rotate, so that the A movable part 10 and the B movable part 20 move away from each other, thereby unfolding the cloth pieces A 01 and B 02, making it easier for the unloading device to remove them for subsequent further processing.

[0027] The stacking bracket is movably mounted on the frame along the B direction. The stacking bracket is connected to a B-movement adjustment mechanism that adjusts its movement along the B direction, which is a horizontal direction perpendicular to the A direction. The structure of the frame and stacking bracket can be specifically selected and adapted according to the stacking device and the type of production line being assembled. Relevant technicians can select the appropriate one based on its function and installation location, and this will not be discussed in detail here. The stacking bracket is also provided with a cloth support member 51, which supports the A side 03 and the B side 04 in the X position. The cloth support member 51 can be movably mounted to prevent the tilting bracket 40 from tilting. Specifically, it can be telescopically mounted along its length, with the length of the cloth support member 51 matching the A direction. The cloth support member 51 can be composed of a long, cantilevered strip. The cloth support member 51 can support the A side 03 and the B side 04 of the cloth piece 01 and the cloth piece 02 that extend outside the A stacking plate 11 and the B stacking plate 21. Secondly, during the sewing process, the cloth supporting piece 51 and the sewing mechanism on the sewing device can be arranged correspondingly to ensure that the A side 03 and the B side 04 can smoothly and reliably enter the sewing mechanism for sewing. During the specific operation, a blowing device can be set on one side, and the blowing device blows the A side 03 to ensure that after the state A is changed to the B state, the A side 03 can be reliably arranged on the A cloth supporting piece 51. During the sewing process, the flip bracket 40 moves along the A direction, and the cloth supporting piece 51 does not move along the A direction. During the specific operation, the B moving adjustment mechanism can be composed of a B moving adjustment cylinder, and the piston rod of the B moving adjustment cylinder is connected to the cloth stacking bracket.

[0028] When the present invention is used in specific operation, Figure 3 As shown, first adjust the stacking device to Figure 3 The left side of the middle state is arranged corresponding to the cloth feeding device, and then the A cloth clamping piece 12 is adjusted to turn over so that the cloth stacking device is turned to Figure 3 In the middle state, the cloth feeding mechanism arranges (lays) the cloth piece A 01 to be taken on the A stacking plate 11 so that the A edge 03 is located outside the A stacking plate 11, and then adjusts the A cloth clamping piece 12 to flip so that the stacking device is transformed into Figure 3 Then adjust the turning bracket 40 to turn over and adjust the cloth supporting piece 51 to extend so that the cloth stacking device turns to the right side. Figure 4 In the middle left state, the A edge 03 is arranged on the cloth supporting member 51. Then adjust the B cloth clamping member 22 to turn the cloth stacking device to Figure 4In the middle state, the cloth feeding mechanism places the cloth piece B 02 to be taken on the B stacking plate 21 so that the B edge 04 is located on the upper side of the A edge 03, and then adjusts the B cloth clamping piece 22 to flip so that the stacking device is transformed into Figure 4 In the middle right state, the cloth piece B 02 is clamped. At this time, the cloth stacking bracket is adjusted to move in the direction B, so that the cloth stacking device and the sewing device are arranged correspondingly, and the cloth supporting piece A 51 and the sewing mechanism are arranged correspondingly. At this time, the flip bracket 40 is adjusted to move in the opposite direction of A, that is, the flip bracket is adjusted from Figure 6 Then adjust the stacking support to move in the opposite direction of direction B, and adjust the A movable member 10 and the B movable member 20 to separate after moving into position, that is, the state of the stacking device is changed from Figure 5 The upper middle state changes to Figure 5 The middle and lower side state is used to unfold the sewn A cloth piece 01 and B cloth piece 02. Figure 5 In the middle and lower state, the A stacking plate 11 and the B stacking plate 21 are not fully unfolded, and preferably the middle part is raised at a small angle. Then the unloading device takes away the sewn cloth pieces A 01 and B 02 for subsequent processing. Then adjust the stacking device to restore to Figure 3 The process is repeated to achieve the continuous overlapping, sewing and unfolding of cloth piece A 01 and cloth piece B 02.

[0029] The beneficial effect of the present invention is as follows: in the above scheme, the cloth feeding device takes the cloth piece A 01 and the cloth piece B 02 one by one and stacks them in an X state on the cloth stacking device, and the cloth stacking device sends the cloth piece A 01 and the cloth piece B 02 in the X state to the sewing device for sewing, thereby realizing the automatic stacking, sewing and unfolding of the cloth piece A 01 and the cloth piece B 02.

[0030] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention.
