Description

Technical Field

[0001] This application relates to the technical field of automatic needle arrangement equipment, and in particular to an automatic loading and unloading mechanism for a needle arrangement machine. Background Technology

[0002] In the textile manufacturing industry, knitting processes can create diverse fabric textures by arranging and combining different types of needle picks. As a core component of knitting machines, the arrangement of the needle picks directly determines the pattern, density, and structural characteristics of the fabric. With the increasing demand for personalized and complex textures in the textile industry, the flexibility and efficiency of needle pick arrangement have become important factors affecting production efficiency and product competitiveness.

[0003] In related technologies, needle selectors are arranged by a needle sorting machine and placed in corresponding trays in a tight sequence. Since the number of needle selectors a tray can hold is limited, when a tray is full, an empty tray needs to be replaced to hold the next batch of needle selectors.

[0004] Regarding the aforementioned technologies, manual pallet replacement requires real-time monitoring of the needle selection plates' placement to select the appropriate time for replacement. Delayed replacement may result in subsequent needle selection plates being unreceived and falling off the pallet. Utility Model Content

[0005] In order to promptly receive the sorted needle selection pieces, this application provides an automatic loading and unloading mechanism for a needle sorting machine.

[0006] The automatic loading and unloading mechanism for a needle stacking machine provided in this application adopts the following technical solution:

[0007] An automatic loading and unloading mechanism for a needle stacking machine includes a tray for stacking a plurality of needle selection pieces, a tray support disposed on the table of the needle stacking machine for placing the tray, a convex block and a concave block for cooperating with the tray and respectively limiting the needle selection pieces, a spare tray support for placing spare trays, a block support for placing spare convex / concave blocks, a first automatic loading component for transferring the tray, and a second automatic loading component for transferring the convex / concave blocks.

[0008] The first automatic feeding component is used to transfer the material tray on the tray support to the material tray support, and the second automatic feeding component is used to transfer the convex block / concave block on the block support platform to the material tray.

[0009] By adopting the above technical solution, if the timing is not right when manually changing the tray, the needle selector may not be received in time and fall off, affecting product quality and production process. The first automatic feeding component can automatically transfer the tray on the spare tray support to the tray support, and the second automatic feeding component can automatically transfer the convex / concave blocks on the stop block stand to the tray. There is no need for frequent manual operation to change the tray and place the convex and concave blocks, reducing manual intervention, thereby improving the working efficiency of the needle sorting machine, speeding up the arrangement and reception of the needle selector, and thus improving the overall production efficiency.

[0010] Furthermore, the first automatic feeding component includes a first linear module mounted on the needle header table, a clamping cylinder and two clamping plates disposed on the first linear module, the clamping cylinder being driven by the first linear module to align with the material tray, and the two clamping plates being driven by the clamping cylinder to move closer or further apart from each other.

[0011] By adopting the above technical solution, the first linear module can precisely drive the clamping cylinder to move on the needle tray table, accurately aligning it with the position of the tray on the preparation tray support and the tray support itself. Once the clamping cylinder is aligned with the tray, it drives the two clamping plates to move closer together, reliably clamping the tray and achieving precise gripping. This precise positioning and gripping function ensures the stability and accuracy of the tray during transfer, preventing the tray from falling or being damaged due to inaccurate gripping position, and guaranteeing the smooth progress of the feeding process.

[0012] Furthermore, the clamping plate has a fixing part for connecting with the clamping cylinder and a clamping part for clamping the material tray, and the width of the clamping plate gradually increases from the fixing part side to the clamping part side.

[0013] By adopting the above technical solution, the width of the clamping plate gradually increases from the fixed part to the clamping part, resulting in a larger contact area between the clamping part and the material tray. Driven by the clamping cylinder, when the clamping plate clamps the material tray, the larger contact area provides a more uniform pressure distribution, thereby increasing the friction on the material tray. This makes the material tray less likely to slip or fall off during clamping and transfer, effectively enhancing the stability of the clamping and ensuring the safety of the material tray during handling.

[0014] Furthermore, the material tray is provided with nylon blocks on both sides for cooperating with the clamping plates, and the two clamping plates are provided with snap-fit ​​protrusions on opposite sides for locking the nylon blocks.

[0015] By adopting the above technical solution, the cooperation between the nylon block and the snap-fit ​​protrusion provides precise positioning for the clamping plate and the tray. During clamping, the snap-fit ​​protrusion accurately engages with the nylon block, ensuring the tray remains relatively fixed in position and preventing horizontal swaying or shifting. This guarantees the tray's positional accuracy during transfer and facilitates precise docking with other components of the needle tray machine. The nylon block possesses a certain degree of elasticity and cushioning properties, acting as a buffer between the snap-fit ​​protrusion and the tray. When the clamping plate tightens the tray, the nylon block absorbs some of the clamping force, preventing excessive pressure and damage to the tray surface caused by the snap-fit ​​protrusion.

[0016] Furthermore, the second automatic feeding assembly includes a second linear module mounted on the platform, a swing cylinder, a gripper drive cylinder, and a stop gripper mounted on the second linear module. The second linear module is provided with a swing cylinder mounting plate. The swing cylinder is located on the upper side of the swing cylinder mounting plate. The swing cylinder mounting plate is provided with a gripper cylinder fixing plate for cooperating with the swing cylinder on the lower side. The stop gripper is mounted on the lower side of the gripper cylinder for clamping a convex stopper / concave stopper.

[0017] By adopting the above technical solution, the second linear module can drive the entire assembly to move linearly on the platform, realizing the horizontal position adjustment of the stop block gripper; the swing cylinder can enable the gripper to swing, increasing the spatial movement dimension of the stop block gripper, allowing the gripper to rotate after clamping the convex / concave stop block, so that the angle of the stop block matches the needle selection plate. The combination of these two technologies allows the stop block gripper to flexibly align with the convex / concave stop blocks on the stop block preparation platform and the target position on the material tray, improving the flexibility and adaptability of the loading operation and meeting the needs of stop block placement at different positions and angles.

[0018] Furthermore, a steel rod is provided in the tray along its length, a steel rod support plate is provided in the tray along its width, a needle selection plate baffle is provided in the tray at a position away from the needle selection plate flipping mechanism, and the nylon block is fixedly connected to the outer walls of both sides of the tray.

[0019] By adopting the above technical solution, the steel bars along the length of the tray and the steel support plates along the width of the tray act as reinforcing ribs. The steel bars can withstand external forces along the length, while the support plates enhance the rigidity of the tray in the width direction. Together, they effectively improve the overall structural strength and rigidity of the tray, making it less prone to deformation when bearing the needle pieces and during handling, thus ensuring the stability and reliability of the tray. Nylon blocks are fixedly connected to the outer walls of both sides of the tray and cooperate with the snap-fit ​​protrusions on the clamping plate. This allows for precise positioning and reliable clamping of the tray when gripped by the clamping plate. The nylon blocks provide a structure adapted to the snap-fit ​​protrusions, enhancing the connection stability between the clamping plate and the tray and ensuring that the tray will not easily fall off during handling.

[0020] Furthermore, the protruding block is integrally connected to two first steps on the side near the needle selection plate frame for abutting against the side wall of the needle selection plate. The two first steps are symmetrically placed near the two ends of the protruding block, and each of the two first steps has an outer inclined surface for abutting against the needle selection plate on the side near the needle selection plate frame.

[0021] By adopting the above technical solution, two first steps are symmetrically arranged near the two ends of the convex block. The first step is close to the outer inclined surface of the needle plate frame, which better conforms to the side wall shape of the needle plate and can limit the needle plate from both sides. When the needle plate is placed in the material tray, the first step abuts against the side wall of the needle plate to prevent the needle plate from shifting in the width direction, ensuring that the needle plates are neatly arranged in the material tray and guaranteeing the accuracy and consistency of the needle plate arrangement.

[0022] Furthermore, the concave block is integrally connected with two second steps on the side away from the needle selection plate frame to abut against the side wall of the needle selection plate. The two second steps are symmetrically placed near the two ends of the concave block, and each of the two second steps has an inner inclined surface for abutting against the needle selection plate on the side away from the needle selection plate frame.

[0023] By adopting the above technical solution, the inner inclined surface design of the second step on the side away from the needle selector holder can perfectly match the shape of the side wall of the needle selector. The two second steps symmetrically distributed near both ends of the concave stop block can stably limit the needle selector from both sides. When the needle selector is placed in the tray, the second step tightly abuts against the side wall of the needle selector, effectively preventing displacement of the needle selector in the width direction, promoting a more regular and orderly arrangement of the needle selectors in the tray, and thus ensuring high precision and consistency in the arrangement of the needle selectors.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The automatic loading and unloading mechanism automatically transfers the material tray from the tray support to the tray support via the first automatic loading component, and automatically transfers the convex / concave blocks from the block support platform to the material tray via the second automatic loading component, reducing manual intervention. The first linear module precisely drives the clamping cylinder to move and grip the material tray, while the second linear module and the swing cylinder work together to realize the multi-dimensional movement of the block gripper to grasp and place the block, speeding up the arrangement and acceptance of the needle selection pieces, improving overall production efficiency, and avoiding the impact on the production process caused by the needle selection pieces falling due to untimely manual tray replacement.

[0026] 2. The gradually widening design of the clamping plate increases the contact area with the material tray, providing a more uniform pressure distribution and friction, thus enhancing clamping stability. The nylon blocks on both sides of the material tray engage with the clamping plate's interlocking protrusions to achieve precise positioning, preventing horizontal swaying or offset of the material tray and ensuring accurate transfer position. Simultaneously, the nylon blocks provide cushioning to prevent damage to the material tray surface. Furthermore, the material tray's internal steel rods and support plates enhance structural strength, preventing tray deformation and further ensuring connection stability.

[0027] 3. The first step of the convex stop and the second step of the concave stop limit the needle selection piece from both sides. Their abutting outer inclined surface and abutting inner inclined surface can better fit the shape of the side wall of the needle selection piece, prevent the needle selection piece from shifting in the width direction, ensure that the needle selection piece is neatly arranged in the material tray, ensure the accuracy and consistency of the arrangement, provide a good foundation for subsequent knitting processes, and ensure product quality.

[0036] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-7 The present application will be further described in detail with reference to the embodiments.

[0037] This application discloses an automatic loading and unloading mechanism for a pin header machine. (Refer to...) Figure 1 The automatic loading and unloading mechanism of the needle plater includes a material tray 1, a material tray 1 support, a spare tray support 3, a convex stop block 4, a concave stop block 5, a stop block spare platform 6, a first automatic loading component 7, and a second automatic loading component 8.

[0038] The material tray 1 is used to hold several needle selector pieces. The material tray 1 support is set on the table of the needle selector machine and is used to place the material tray 1. The spare material tray support 3 is used to place the spare material tray 1. Both the convex and concave blocks 5 are placed on the material tray 1 to cooperate with the material tray 1 and limit the needle selector pieces respectively. The block stand 6 is used to place spare convex / concave blocks 5. The first automatic feeding component 7 can transfer the spare material tray 1 on the spare material tray support 3 to the material tray 1 support of the needle selector support mechanism. The second automatic feeding component 8 can transfer the spare blocks on the block stand 6 to the material tray 1.

[0039] Reference Figure 2 In this embodiment, a steel rod is provided inside the material tray 1 along the length direction, a steel rod support plate 12 is provided inside the material tray 1 along the width direction, a needle selection plate baffle 13 is provided inside the material tray 1 at a position away from the needle selection plate flipping mechanism, and nylon blocks 14 for cooperating with the first automatic feeding component 7 are symmetrically arranged and fixedly connected on the outer walls of both sides of the material tray 1.

[0040] Reference Figure 3 and Figure 4The protruding block has two integrally connected first steps 41 on the side near the needle holder, which are used to abut against the side wall of the needle holder. The two first steps 41 are symmetrically positioned near both ends of the protruding block. Each of the two first steps 41 has an outer inclined surface 42 for abutting against the needle holder on the side near the needle holder. The two first steps 41 are symmetrically positioned near both ends of the protruding block. The outer inclined surface 42 of the first step 41 near the needle holder allows it to better fit the shape of the side wall of the needle holder and can limit the needle holder from both sides.

[0041] The recessed block 5 has two integrally connected second steps 51 on the side away from the needle plate holder, which are used to abut against the side wall of the needle plate. The two second steps 51 are symmetrically positioned near both ends of the recessed block 5. Each of the two second steps 51 has an inner inclined surface 52 for abutting against the needle plate on the side away from the needle plate holder. The design of the inner inclined surface 52 of the second step 51 on the side away from the needle plate holder allows it to closely match the shape of the side wall of the needle plate. The two second steps 51 symmetrically distributed near both ends of the recessed block 5 can stably limit the needle plate from both sides.

[0042] Reference Figure 5 and Figure 6 The first automatic feeding component 7 includes a first linear module 71, a clamping cylinder 72, and clamping plates 73. In this embodiment, there are two clamping plates 73 arranged symmetrically. The first linear module 71 is mounted on the table of the needle feeding machine. The clamping cylinder 72 is mounted on the first linear module 71 and driven by the first linear module 71 to move horizontally and vertically to align with the material tray 1. The two clamping plates 73 are symmetrically arranged on both sides of the clamping cylinder 72 and are driven by the clamping cylinder 72 to move closer or further apart from each other.

[0043] The clamping plate 73 has a fixing part 731 for connecting to the clamping cylinder 72 and a clamping part 732 for clamping the material tray 1. The width of the clamping plate 73 gradually increases from the fixing part 731 side to the clamping part 732 side. The clamping parts 732 of the two clamping plates 73 are provided with snap-fit ​​protrusions 733 on opposite sides for locking the nylon block 14.

[0044] The width of the clamping plate 73 gradually increases from the fixing part 731 to the clamping part 732, resulting in a larger contact area between the clamping part 732 and the material tray 1. Driven by the clamping cylinder 72, when the clamping plate 73 clamps the material tray 1, the larger contact area provides a more uniform pressure distribution, thereby increasing the friction on the material tray 1 and making it less likely for the material tray 1 to slip or fall off during clamping and transfer. The cooperation between the nylon block 14 and the snap-fit ​​protrusion 733 provides precise positioning for the clamping plate 73 and the material tray 1. During clamping, the snap-fit ​​protrusion 733 can accurately engage with the nylon block 14, making the position of the material tray 1 relatively fixed when clamped, avoiding wobbling or displacement of the material tray 1 in the horizontal direction.

[0045] Reference Figure 7 The second automatic feeding assembly 8 includes a second linear module 81, a swing cylinder 82, a gripper drive cylinder 83, and a stop gripper 84. The second linear module 81 is mounted on the table of the needle feeding machine. A mounting plate for the swing cylinder 82 is slidably mounted on the second linear module 81, and the swing cylinder 82 is mounted on the upper side of the mounting plate. A gripper cylinder fixing plate 831 for cooperating with the swing cylinder 82 is fixedly connected to the lower side of the mounting plate. The stop gripper 84 is mounted on the lower side of the gripper cylinder, thereby aligning with the upper part of the stop platform 6 for gripping the convex / concave stop block 5.

[0046] The second linear module 81 can drive the entire assembly to move horizontally or vertically on the platform, enabling the position adjustment of the stop block gripper 84 in the horizontal and vertical directions. The swing cylinder 82 enables the gripper to swing, increasing the spatial movement dimension of the stop block gripper 84. The gripper can rotate after clamping the convex / concave stop block 5, so that the angle of the stop block matches the needle selection plate. The stop block gripper 84 can flexibly align with the convex / concave stop block 5 on the stop block preparation table 6 and the target position on the material tray 1, improving the flexibility and adaptability of the loading operation and meeting the requirements for stop block placement at different positions and angles.

[0047] The implementation principle of the automatic loading and unloading mechanism of the needle sorting machine according to the embodiments of this application is as follows: The material tray 1 is used to stack needle sorting pieces. The material tray 1 has a steel rod along the length direction and a steel rod support plate 12 along the width direction to enhance the structural strength of the material tray 1. The nylon blocks 14 on both sides of the outer wall of the material tray 1 cooperate with the clamping plate 73 of the first automatic loading component 7. The two first steps 41 of the convex block near the needle sorting piece frame can fit against the side wall of the needle sorting piece by abutting the outer inclined surface 42, limiting the needle sorting piece from both sides; the two second steps 51 of the concave block 5 away from the needle sorting piece frame can fit against the side wall of the needle sorting piece by abutting the inner inclined surface 52, similarly limiting the needle sorting piece from both sides to ensure that the needle sorting pieces are neatly arranged in the material tray 1.

[0048] The first automatic feeding component 7 transfers the tray 1, which is full of needle selector discs, from the tray 1 support to the downstream station, and then transfers the spare tray 1 from the spare tray support 3 to the tray 1 support to receive the next batch of needle selector discs. The second automatic feeding component 8 transfers the spare convex block 4 / concave block 5 from the stop block stand 6 to the corresponding positions in the tray 1.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
