[0025] As shown in Figures 1 and 2, a cloth stacking device for patchwork production includes a stacking mechanism provided with a stacking portion configured to arrange cloth piece A 01 and cloth piece B 02 in an X-position. The X-position refers to a corresponding arrangement of edge A 03 on cloth piece A 01 and edge B 04 on cloth piece B 02, and edges A 03 and B 04 are capable of being sewn. Edge A 03 is the edge of cloth piece A 01 that is pre-set for splicing with cloth piece B 02, and edge B 04 is the edge of cloth piece B 02 that is pre-set for splicing with cloth piece A 01. The quilt stacking device provided by the present invention is used in an automated quilt cover production system, specifically an automated production line for splicing quilt covers, and is assembled between a cloth piece loading device and a sewing device. Specifically, the cloth piece loading device takes cloth piece A 01 and cloth piece B 02 and places them on the quilt folding device. The quilt folding device and the sewing device are then adjusted to align them, sewing edge A 03 and edge B 04, thereby completing the splicing process of cloth piece A 01 and cloth piece B 02. The cloth piece loading device can be implemented using two separate groups to load cloth piece A 01 and cloth piece B 02, or a single group. The cloth piece loading device and sewing device can be implemented using existing publicly available solutions.

[0026] The specific solution is as follows: the stacking section includes a stacking assembly, on which fabric piece A 01 and fabric piece B 02 are laid (flat or unfolded). The stacking assembly comprises a stacking unit A and a stacking unit B. Fabric piece A 01 is laid on stacking unit A, and fabric piece B 02 is laid on stacking unit B. The stacking assembly is connected to a stacking adjustment mechanism, which adjusts the stacking assembly between two states: A and B. State A is when stacking unit A is ready to receive fabric piece A 01; state B is when stacking unit B is ready to receive fabric piece B 02. The A cloth-stack unit includes an A cloth-stack plate 11 and an A cloth-clamping member 12 movably mounted corresponding to the A cloth-stack plate 11. The A cloth-clamping member 12 is connected to an A cloth-clamping adjustment mechanism. The A cloth-clamping adjustment mechanism adjusts the A cloth-clamping member 12 to have an A1 state and an A2 state. In the A1 state, the A cloth-clamping member 12 and the A cloth-stack plate 11 are separated, and the A cloth-stack plate 11 is arranged horizontally to receive the A cloth piece 01. In the A2 state, the A cloth-clamping member 12 is arranged close to the A cloth-stack plate 11 to clamp the A cloth piece 01. The B cloth stacking unit includes a B cloth stacking plate 21 and a B cloth clamping piece 22 movably installed corresponding to the B cloth stacking plate 21. The B cloth clamping piece 22 is connected to the B cloth clamping adjustment mechanism. The B cloth clamping adjustment mechanism adjusts the B cloth clamping piece 22 to have a B1 state and a B2 state. In the B1 state, the B cloth clamping piece 22 and the B cloth stacking plate 21 are separated, and the B cloth stacking plate 21 is arranged horizontally to receive the B cloth piece 02; in the B2 state, the B cloth clamping piece 22 is arranged close to the B cloth stacking plate 21 to clamp the B cloth piece 02. One side of the A stacking plate 11 and one side of the B stacking plate 21 are pivotally assembled via the A shaft 31. One side of the A clamping member 12 and the other side of the A stacking plate 11 are pivotally mated, and one side of the B clamping member 22 and the other side of the B stacking plate 21 are pivotally mated. In the A position, the A stacking plate 11 is positioned above the B stacking plate 21, while in the B position, the B stacking plate 21 is positioned above the A stacking plate 11. A further embodiment is that the stacking adjustment mechanism further adjusts the stacking assembly to a C position. In the C position, the A stacking plates 11 and B stacking plates 21 are in an expanded configuration (i.e., the A stacking plates 11 and B stacking plates 21 are arranged horizontally from side to side). Prior to this, the other side edge of the A cloth stacking plate 11 is provided with an A movable part 10, and the A cloth stacking plate 11 and the A movable part 10 are rotationally assembled and connected, and one side edge of the A cloth clamping part 12 is rotatably installed on the A movable part 10, and the other side edge of the B cloth stacking plate 21 is provided with a B movable part 20, and the B cloth stacking plate 21 and the B movable part 20 are rotationally assembled and connected, and one side edge of the B cloth clamping part 22 is rotatably installed on the B movable part 20, and the A movable part 10 and the B movable part 20 are respectively movably installed on the flip bracket 40 along the A direction, and the A direction is a direction perpendicular to the A axis 31, and the middle part of the flip bracket 40 is rotatably installed on the cloth stacking bracket through the B axis assembly 41.The flip bracket 40 is also movably mounted on the stacking bracket along direction A. The flip bracket 40 is connected to an A movement adjustment mechanism that adjusts its movement along direction A. The stacking adjustment mechanism includes an A1 stacking adjustment unit and an A2 stacking adjustment unit. The A1 stacking adjustment unit adjusts the flip bracket 40 to flip, and the A2 stacking adjustment unit adjusts the A movable member 10 and the B movable member 20 to move closer to or further from each other. During operation, one side edge of the A stacking plate 11 and one side edge of the B stacking plate 21 can be assembled and connected using a hinge. The ends of the A movable member 10 and the B movable member 20 are slidably mounted on the flip bracket 40 along direction A. The A assembly nut and the B assembly nut are respectively provided in the middle of the A movable member 10 and the B movable member 20. The A2 stacking adjustment unit includes an adjustment screw that is rotatably mounted on the flip bracket 40. The adjustment screw has an A adjustment section 43 and a B adjustment section 42. The A adjustment section 43 and the B adjustment section 42, together with the A assembly nut and the B assembly nut, respectively, form a screw nut adjustment mechanism. The threads of the A adjustment section 43 and the B adjustment section 42 have opposite rotation directions. The adjusting screw is connected to the A2 adjustment motor 44 that drives it to rotate. Rotating the adjusting screw causes the A movable part 10 and the B movable part 20 to move closer to or farther away from each other. A recessed A mounting portion 13 is provided in the middle of the A movable part 10, and the A stacking plate 11 and the A cloth clamping member 12 are mounted in the A mounting portion 13. During specific operation, the other side edge of the A stacking plate 11 is rotatably mounted on the A movable part 10 via two A ear shafts. One side edge of the A cloth clamping member 12 is rotatably mounted on the A movable part via two A1 ear shafts. The A cloth clamping adjustment mechanism includes an A cloth clamping drive motor mounted on the A movable part 10, and the A cloth clamping drive motor is transmission-connected to the A1 ear shaft. The other side edge of the B stacking plate 21 is rotatably mounted on the B movable part 20 via two B ear shafts. A recessed B mounting portion 23 is located in the center of movable member B 20, within which the B stacking plate 21 and B clamping member 22 are mounted. During operation, one side of the B clamping member 22 is pivotally mounted on movable member B 20 via two B1 trunnions. The B clamping adjustment mechanism includes a B clamping drive motor mounted on movable member B 20, in a driving connection with the B1 trunnions. More specifically, the B-axis assembly 41 can be composed of a B assembly set 411 and a B assembly shaft section 412 provided on both sides of the flip bracket 40. The A movement adjustment mechanism includes an A movement adjustment cylinder 47, which is assembled on the cloth stacking bracket. The B assembly set 411 and the piston rod of the A movement adjustment cylinder 47 are rotatably assembled. The B assembly shaft section 412 is a spline shaft section. The A1 cloth stacking adjustment unit includes an A1 adjustment motor 46 and an A spline shaft sleeve 45 that is transmission-connected to the A1 adjustment motor 46. 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 drives 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] During the specific operation of the present invention, as shown in FIG3 , the stacking device is first adjusted to the left side of FIG3 and arranged correspondingly with the cloth loading device. Then, the cloth clamping member A 12 is adjusted to flip so that the stacking device rotates to the middle position in FIG3 . The cloth loading mechanism arranges (lays) the taken cloth piece A 01 on the A stacking plate 11 so that the A edge 03 is located outside the A stacking plate 11. Then, the cloth clamping member A 12 is adjusted to flip so that the stacking device rotates to the right side of FIG3 , thereby clamping the cloth piece A 01. The flip bracket 40 is then adjusted to flip and the cloth support member 51 is extended, so that the stacking device rotates to the left side of FIG4 , with the A edge 03 arranged on the cloth support member 51. Then, the B clamping member 22 is adjusted to flip so that the stacking device is in the middle position in Figure 4. The cloth feeding mechanism places the B cloth piece 02 on the B stacking plate 21 so that the B edge 04 is located above the A edge 03. Then, the B clamping member 22 is adjusted to flip so that the stacking device is in the right position in Figure 4, clamping the B cloth piece 02. At this time, the stacking bracket is adjusted to move in the B direction so that the stacking device is arranged in a corresponding manner with the sewing device, and the A cloth supporting member 51 is arranged in a corresponding manner with the sewing mechanism. At this time, the flip bracket 40 is adjusted to move in the opposite direction of the A direction, that is, the flip bracket is rotated from the lower position in Figure 6 to the upper position. Then, the stacking bracket is adjusted to move in the direction opposite to the B direction. After moving into place, the A movable member 10 and the B movable member 20 are adjusted to separate, that is, the stacking device is rotated from the upper position in Figure 5 to the lower position in Figure 5, thereby unfolding the sewn cloth pieces A 01 and B 02. In the lower position shown in Figure 5, stacking plates A 11 and B 21 are not fully unfolded; their midsections are preferably slightly raised upward. The unloading device then removes the sewn fabric panels A 01 and B 02 for subsequent processing. The stacking device is then adjusted back to the left position shown in Figure 3. This process is repeated, achieving the continuous stacking, sewing, and unfolding of fabric panels A 01 and 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. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
