Description

Technical Field

[0001] This invention relates to the field of automated garment sewing equipment, and more particularly to a retractable mechanism for folding and accommodating high-neck fabrics. Background Technology

[0002] In the sewing process of turtleneck garments, concealed stitching is a crucial step that determines the appearance quality and wearing comfort of the collar. In this process, the inner and outer turtleneck pieces must first be precisely overlapped and positioned, and then concealed stitching is performed along a pre-set track, hiding the seams inside the fabric, resulting in a smooth collar appearance. In actual processing, the outer turtleneck piece is usually larger than the inner turtleneck piece. When overlapping, the two diagonal edges of the outer turtleneck piece must be precisely aligned with the two diagonal edges of the inner turtleneck piece to the sewing position. This process is known in the garment industry as "alignment." Inaccurate alignment will lead to misalignment of the concealed stitches and distortion of the collar shape, directly affecting the quality of the finished product. However, because turtleneck fabrics are mostly flexible, soft, and highly elastic, they are prone to misalignment during stacking. Furthermore, the turtleneck's three-dimensional curved structure requires the inner and outer turtleneck pieces to maintain precise relative positions under specific curved surfaces, further increasing the difficulty of stacking and positioning.

[0003] Currently, the mainstream processing method in the industry is still manual stacking and sewing, where workers align and stack the turtleneck lining and outer turtleneck pieces before feeding them into a sewing machine for blind stitching. This method is labor-intensive, and the stacking accuracy varies from person to person, making it difficult to guarantee stitch consistency and meet the needs of large-scale, standardized production.

[0004] In existing automation solutions, industrial robots mostly only handle the feeding and handling of cut pieces; the stacking and positioning of lining and outer pieces still rely on specialized fixtures. However, existing fixtures are mostly one-piece structures, and their clamping components cannot be individually removed after stacking and positioning, limiting the flexibility of process arrangement. Furthermore, existing fixtures can only maintain the current stacked state of the fabric when clamping, and cannot actively adjust the relative position between the lining and outer pieces. When there is an initial deviation in stacking, this deviation will be retained in the sewing process. Summary of the Invention

[0005] In view of the above-mentioned deficiencies of the prior art, the present invention provides a retractable mechanism for accommodating the stacking of turtleneck fabrics, which can improve the alignment accuracy when the inner and outer turtleneck pieces are stacked, and provide unobstructed space for subsequent sewing operations.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] This invention provides a retractable mechanism for accommodating stacked turtleneck fabrics, comprising a first support member, a second support member, and a pressing member. The first support member supports the turtleneck lining, the second support member is positioned above the first support member and supports the turtleneck outer piece, and the second support member is capable of horizontal reciprocating relative to the first support member. The pressing member is positioned above the second support member and is capable of lifting and lowering relative to the second support member. The second support member has a accommodating block, and the pressing member has a corresponding accommodating groove. The accommodating groove has an opening in the moving direction of the second support member for the accommodating block to slide out. When the pressing member descends and presses, the accommodating block is embedded in the accommodating groove. When the second support member retracts, the accommodating block slides out of the accommodating groove from the opening.

[0008] Preferably, at least two receiving blocks are provided, and each receiving block is arranged at intervals in a direction perpendicular to the moving direction of the second support member, and the receiving groove and the receiving block are correspondingly matched in position.

[0009] Preferably, it also includes a cylinder, which is fixedly mounted on the first support member, and the extension rod of the cylinder is connected to the second support member.

[0010] Preferably, it also includes a fixing plate, on which both the first support and the cylinder are fixed.

[0011] Preferably, it also includes an adjusting plate with a waist-shaped hole, the adjusting plate being connected to the telescopic rod of the cylinder through the waist-shaped hole, and the second support being fixedly connected to the adjusting plate.

[0012] Preferably, there are two cylinders and two second support members, and the telescopic rods of the two cylinders are respectively connected to the two second support members.

[0013] Preferably, the extension and retraction directions of the two second support members are parallel to the two oblique sides of the high collar lining, and the orthographic projection of the two second support members above the first support member is located within the orthographic projection range of the high collar lining above the first support member.

[0014] Preferably, it also includes a lifting assembly, through which the pressing member is vertically and vertically positioned above the second support member.

[0015] Preferably, the lifting assembly includes a fixed gimbal, a lifting cylinder, a lifting guide rail, and a mounting plate. The lifting cylinder is fixed to the fixed gimbal, the lifting guide rail is vertically mounted on the fixed gimbal, the mounting plate is slidably mounted on the lifting guide rail and is lifted and lowered under the drive of the lifting cylinder, and the pressing component is fixed to the mounting plate.

[0016] Preferably, the pressed part is provided with a reinforcing plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The retractable mechanism for accommodating stacked turtleneck fabrics of the present invention, through the cooperation of accommodating blocks and accommodating grooves respectively provided on the second support and the pressing component, moves the outer turtleneck piece relative to the inner turtleneck piece to the accommodating position when the pressing component descends and presses, thereby achieving precise alignment of the oblique edges on both sides of the outer turtleneck piece and the inner turtleneck piece. This solves the problem that existing clamps cannot actively adjust the relative position of the cut pieces, and effectively improves the positional accuracy and consistency of the concealed stitching.

[0019] Meanwhile, the opening in the receiving groove in the moving direction of the second support allows the receiving block to slide horizontally out from the opening when the second support is removed, realizing the independent removal of the second support after pressing, avoiding disturbance to the already positioned stacked fabric, providing unobstructed space for subsequent sewing operations, without the need for manual or additional mechanism intervention, simplifying the process and improving production efficiency.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0030] See Figure 1 and Figure 2 This embodiment provides a retractable mechanism for accommodating stacked turtleneck fabrics, including a first support 1, a second support 2, and a pressing member 3. The first support 1 supports the turtleneck lining 4, the second support 2 is positioned above the first support 1 and supports the turtleneck outer lining 5, and the second support 2 can reciprocate horizontally relative to the first support 1. The pressing member 3 is positioned above the second support 2 and can rise and fall relative to the second support 2. The second support 2 is provided with a accommodating block 6, and the pressing member 3 is provided with a corresponding accommodating groove 7. The accommodating groove 7 has an opening in the moving direction of the second support 2 for the accommodating block 6 to slide out. When the pressing member 3 descends and presses, the accommodating block 6 is embedded in the accommodating groove 7. When the second support 2 retracts, the accommodating block 6 slides out of the opening into the accommodating groove 7.

[0031] The retractable mechanism for accommodating stacked turtleneck fabric in this embodiment utilizes the cooperation of accommodating blocks 6 and accommodating grooves 7 respectively provided on the second support member 2 and the pressing member 3. When the pressing member 3 descends to press, the outer turtleneck piece 5 moves relative to the inner turtleneck piece 4 to the accommodating position, achieving precise alignment of the diagonal edges of the outer turtleneck piece 5 and the inner turtleneck piece 4. This solves the problem that existing clamps cannot actively adjust the relative positions of the cut pieces, effectively improving the positional accuracy and consistency of the concealed stitching. Simultaneously, the opening in the accommodating groove 7 along the moving direction of the second support member 2 allows the accommodating blocks 6 to slide horizontally out from the opening when the second support member 2 retracts. This enables the independent removal of the second support member 2 after pressing, avoiding disturbance to the already positioned stacked fabric and providing unobstructed space for subsequent sewing operations. No manual or additional mechanism intervention is required, simplifying the process and improving production efficiency.

[0032] Preferably, at least two receiving blocks 6 are provided, and each receiving block 6 is arranged at intervals in a direction perpendicular to the moving direction of the second support member 2. The receiving groove 7 corresponds to and cooperates with the receiving blocks 6 in position. When the pressing member 3 is pressed, multiple receiving blocks 6 and receiving grooves 7 cooperate simultaneously to form multiple positioning constraint points, so that the two beveled sides of the large high collar outer piece 5 are precisely aligned with the two beveled sides of the high collar inner piece 4 to the sewing position, avoiding the high collar outer piece 5 from being skewed or misaligned when stacked due to its large area, and ensuring that the stitches of the subsequent blind stitching are accurate and consistent.

[0033] Preferably, see Figure 1 and Figure 2 The retractable mechanism for arranging high-neck fabric stacking in this embodiment also includes a cylinder 8, which is fixedly mounted on the first support member 1, and the telescopic rod of the cylinder 8 is connected to the second support member 2. The second support member 2 is driven by the cylinder 8 to move horizontally reciprocally. It has a simple structure and fast action response, and can meet the working conditions of frequent and rapid switching between the second support member 2 and the retractable position.

[0034] Preferably, see Figure 1 and Figure 2 The retractable mechanism for arranging high-neck fabric stacking in this embodiment also includes a fixing plate 9, on which the first support 1 and the cylinder 8 are both fixed. The fixing plate 9 serves as a common mounting base for the first support 1 and the cylinder 8, ensuring the relative position between the first support 1 and the cylinder 8. This simplifies the alignment adjustment process during assembly and helps ensure the consistency between the extension / retraction direction of the cylinder 8 and the movement direction of the second support 2.

[0035] Preferably, see Figure 3The retractable mechanism for arranging high-neck fabric stacking in this embodiment also includes an adjusting plate 10. The adjusting plate 10 has a waist-shaped hole 11 and is connected to the telescopic rod of the cylinder 8 through the waist-shaped hole 11. The second support member 2 is fixedly connected to the adjusting plate 10. The installation position of the adjusting plate 10 on the telescopic rod of the cylinder 8 can be finely adjusted along the length direction of the waist-shaped hole 11. The initial position correction of the second support member 2 can be achieved without replacing parts, reducing assembly and debugging difficulty and improving the maintainability of the equipment and its adaptability to high-neck fabric pieces of different specifications.

[0036] Preferably, see Figure 1 and Figure 2 There are two cylinders 8 and two second support members 2. The telescopic rods of the two cylinders 8 are respectively connected to the two second support members 2. The two second support members 2 are driven by independent cylinders 8, so that the two second support members 2 can provide support for the high collar outer piece 5 from both sides, adapting to the non-parallel extension shape of the diagonal sides of the high collar piece, and ensuring that the high collar outer piece 5 is subjected to balanced force and stable position during the support and pressing process.

[0037] Preferably, the extension and retraction directions of the two second support members 2 are parallel to the two oblique sides of the high-necked lining 4, and the orthographic projections of the two second support members 2 above the first support member 1 are located within the orthographic projection range of the high-necked lining 4 above the first support member 1. Since the high-necked lining 4 has a three-dimensional arc surface structure and the two oblique sides extend non-parallel, the two second support members 2 are extended and retracted along the two oblique sides respectively, so that each second support member 2 remains parallel to the oblique side on the corresponding side. This avoids the second support member 2 extending beyond the contour range of the high-necked lining 4 and interfering with other components, ensuring that the second support member 2 always accurately supports the underside of the high-necked outer piece 5, providing precise support for the stable placement and subsequent stacking of the high-necked outer piece 5.

[0038] Preferably, see Figure 1 and Figure 2 The retractable mechanism for accommodating stacked turtleneck fabric in this embodiment also includes a lifting assembly 12. The pressing member 3 is vertically and vertically positioned above the second support member 2 via the lifting assembly 12. The lifting assembly 12 drives the pressing member 3 to rise and fall relative to the second support member 2, enabling the pressing member 3 to descend and press the turtleneck outer piece 5 when the second support member 2 is in a supporting state, and to rise and release the fabric when needed, thus achieving automated control of the pressing action.

[0039] Preferably, see Figure 4The lifting assembly 12 includes a fixed gimbal 1201, a lifting cylinder 1202, a lifting guide rail 1203, and a mounting plate 1204. The lifting cylinder 1202 is fixed to the fixed gimbal 1201, the lifting guide rail 1203 is vertically mounted on the fixed gimbal 1201, and the mounting plate 1204 is slidably mounted on the lifting guide rail 1203 and is lifted and lowered under the drive of the lifting cylinder 1202. The pressing component 3 is fixed to the mounting plate 1204. The lifting guide rail 1203 provides precise guidance for the lifting and lowering movement of the mounting plate 1204, ensuring that the pressing component 3 always maintains the preset trajectory and posture during the lifting and lowering process. This allows the pressing component 3 to press the high collar outer piece 5 at the correct angle and position, ensuring accurate fit and uniform force between the high collar outer piece 5 and the receiving block 6 during pressing, thereby further improving the consistency and reliability of stacking and receiving.

[0040] Preferably, the pressing component 3 is provided with a reinforcing plate to enhance the overall structural rigidity of the pressing component 3, effectively preventing the pressing component 3 from bending and deforming during long-term use or under uneven stress, and avoiding the impact on stacking positioning accuracy caused by local loose pressing or uneven stress on the fabric due to deformation of the pressing component 3.

[0041] See Figures 1 to 4 The working process of the retractable mechanism for accommodating high-neck fabric stacking in this embodiment is as follows:

[0042] First, the turtleneck lining 4 is placed on the upper surface of the first support 1. Driven by the cylinder 8, the second support 2 moves horizontally from its initial position to above the first support 1 and stops at the supporting position, at which point the second support 2 is positioned above the turtleneck lining 4. Then, the turtleneck outer piece 5 is placed on the upper surface of the second support 2, so that the turtleneck outer piece 5 and the turtleneck lining 4 are separated in the height direction by the second support 2.

[0043] Then, the pressing component 3 descends under the drive of the lifting assembly 12. During the descent, the receiving groove 7 on the pressing component 3 gradually approaches the receiving block 6 on the second support component 2, and finally the receiving block 6 is embedded in the receiving groove 7, forming a clearance fit. Afterwards, the pressing component 3 continues to descend until it presses down on the upper surface of the turtleneck outer piece 5 and presses the turtleneck outer piece 5 onto the turtleneck inner piece 4. During the pressing process, due to the guiding effect of the cooperation between the receiving block 6 and the receiving groove 7, the pressing component 3 causes the turtleneck outer piece 5, which has a larger area, to produce a slight displacement relative to the turtleneck inner piece 4, so that the two beveled sides of the turtleneck outer piece 5 are precisely moved to the sewing position relative to the two beveled sides of the turtleneck inner piece 4, achieving the receiving position.

[0044] Subsequently, driven by cylinder 8, the second support 2 moves horizontally from the supporting position to the withdrawing position, and the receiving block 6 slides horizontally out from the opening of the receiving groove 7, completely removing the second support 2 from between the turtleneck outer piece 5 and the turtleneck inner piece 4. At this time, since the pressing member 3 has pressed the turtleneck outer piece 5 onto the turtleneck inner piece 4, the withdrawal action of the second support 2 will not disturb the relative position of the already stacked and positioned turtleneck inner piece 4 and turtleneck outer piece 5. After the second support 2 withdraws, the pressing member 3 remains in the pressing state, and the stacked turtleneck inner piece 4 and turtleneck outer piece 5 are in a state where they can be taken away or transferred to the next process.

[0045] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
