Description

Technical Field

[0001] This application relates to the technical field of automatic arranging equipment for selecting needle pieces, and particularly relates to a needle piece arranging machine for selecting needle pieces. Background Art

[0002] In the textile manufacturing industry, the weaving process can form diverse fabric patterns by arranging and combining different types of selecting needle pieces. As the core component of a loom, the arrangement of the selecting needle pieces directly determines the pattern, density, and structural characteristics of the fabric. With the increasing demand for personalized and complex patterns in the textile industry, the flexibility and efficiency of the arrangement of the selecting needle pieces have become important factors affecting production efficiency and product competitiveness.

[0003] In the related art, the arrangement of the selecting needle pieces mainly relies on manual operation. Technicians need to manually select different types of selecting needle pieces according to the design requirements and adjust their positions and combination sequences one by one. This process not only requires the operator to have rich experience but also needs to be repeatedly verified to avoid arrangement errors. Although some enterprises have tried to introduce semi-automatic auxiliary tools such as template positioning or simple mechanical jigs, the core model matching and sequence arrangement still mainly rely on manual operation, making it difficult to achieve efficient and accurate mass production.

[0004] In view of the above-mentioned related art, the method of manual needle arrangement has low efficiency. Especially under the requirement of complex patterns, the time consumption increases exponentially. At the same time, manual operation is easily affected by factors such as fatigue and experience differences, resulting in a high error rate of arrangement and easy generation of fabric defects. Summary of the Invention

[0005] In order to improve the problem of low efficiency of manual needle arrangement, reduce the arrangement error rate, and improve the fabric quality, this application provides a needle piece arranging machine for selecting needle pieces.

[0006] The needle piece arranging machine for selecting needle pieces provided by this application adopts the following technical solutions: A needle piece arranging machine for selecting needle pieces includes a plurality of needle piece racks for holding different types of selecting needle pieces, a needle piece conveying mechanism arranged below the needle piece racks and used for receiving and conveying a plurality of selecting needle pieces, a needle piece supporting mechanism arranged at the end of the needle piece conveying mechanism, and a table board and a cabinet for arranging each mechanism; Each of the needle piece racks is installed on the table board and arranged at equal intervals along the conveying direction of the needle piece conveying mechanism. Each of the needle piece racks is provided with a needle piece pushing mechanism for pushing out a single selecting needle piece.

[0007] By adopting the above technical solution, multiple needle selector racks are arranged at equal intervals along the conveying direction of the needle selector conveying mechanism, and each needle selector rack is provided with a needle selector pushing mechanism, which can quickly push out needle selectors of different models and convey them through the needle selector conveying mechanism. Compared with manually selecting and arranging needle selectors one by one, the needle arrangement time is reduced and the needle arrangement efficiency is improved. The needle arrangement machine completes the pushing and conveying of the needle selectors through a mechanical structure, reduces the arrangement errors caused by factors such as fatigue and experience differences in manual operation, and improves the accuracy of needle selector arrangement.

[0008] Furthermore, the needle selection piece conveying mechanism includes two conveying screws arranged parallel to each other and a driving assembly for controlling the rotation of the screws. A screw support bracket for rotationally connecting the conveying screws is provided on the table. The conveying screw is located below the needle selection piece pushing mechanism to receive the needle selection piece. The conveying screw is provided with a plurality of threaded grooves along the length direction of the outer wall for a single needle selection piece to be inserted into. The two conveying screws are respectively provided with needle selection guide strips for limiting the displacement of the needle selection piece on opposite sides.

[0009] By adopting the above technical solution, the several thread grooves provided along the length direction of the conveying screw for the insertion of a single needle selector can ensure that each needle selector is accurately inserted into the corresponding position, thereby realizing the orderly conveying of a single needle selector. It prevents the needle selectors from colliding with each other, being misaligned or falling off during the conveying process, ensures the accuracy of the needle selector conveying, and provides a basis for the subsequent accurate needle arrangement. The two conveying screws arranged in parallel with each other and the needle selection guide strips arranged on the opposite sides thereof together constitute a stable needle selection conveying channel. The needle selection guide strips can limit the displacement of the needle selector so that it can only move along a predetermined path during the conveying process without lateral deviation, shaking or falling, further improving the stability and reliability of the needle selector conveying and reducing the risk of incorrect arrangement of the needle selector.

[0010] Furthermore, a needle selector jack flipping mechanism for flipping a needle selector jack in a horizontal posture to a vertical posture is provided between the needle selector jack supporting mechanism and the needle selector jack conveying mechanism; The needle selection plate flipping mechanism includes a flip wheel, a flip core shaft and a flip driving member for driving the flip core shaft. The flip core shaft is vertically inserted and fixedly connected to the central axis position of the flip wheel, the flip driving member is connected to one end of the flip core shaft, and the flip wheel is circumferentially provided with ratchets for driving the needle selection plate.

[0011] By adopting the above technical solutions, in terms of the coherence of the conveying process, the conveying mechanism conveys the selecting needle pieces of various models in a horizontal order, collects the selecting needle pieces of different models from multiple selecting needle piece racks and advances them orderly, providing guarantee for the subsequent accurate needle arranging. For the final needle arranging requirement, the selecting needle pieces of various models need to be closely arranged in a vertical state in a predetermined order. The flipping mechanism drives the flipping mandrel by means of a flipping driving member, and then drives the flipping wheel piece to rotate. The ratchet teeth on the circumferential direction of the flipping wheel piece drive the selecting needle piece to achieve attitude flipping, changing the selecting needle piece from a horizontal placement state to a vertical state, meeting the specific needle arranging process requirements and enabling the selecting needle pieces to be closely arranged. The whole process has a high degree of automation, reduces manual intervention, lowers the complexity and labor intensity of manual operation, and at the same time improves the efficiency and accuracy of attitude conversion.

[0012] Further, an auxiliary pushing component for pushing the stacked selecting needle pieces into the selecting needle piece supporting mechanism is provided at the upper position of the selecting needle piece flipping mechanism.

[0013] By adopting the above technical solutions, the auxiliary pushing component can timely and accurately push the selecting needle pieces stacked above the flipping mechanism into the selecting needle piece supporting mechanism. It avoids the backlog of selecting needle pieces at the flipping mechanism, ensures the coherence of the whole selecting needle piece conveying process, and prevents the subsequent needle arranging operation from being affected by the stacking of selecting needle pieces. During the process of pushing the selecting needle pieces from the flipping mechanism to the supporting mechanism, the auxiliary pushing component can finely adjust the position of the selecting needle pieces, enabling the selecting needle pieces to more accurately fall into the predetermined position of the supporting mechanism, creating favorable conditions for the subsequent close arrangement and accurate needle arranging.

[0014] Further, the driving component includes a driving wheel, a driven wheel, a synchronous belt and a screw driving motor. A motor support plate for installing the screw driving motor is provided on the platen. The driving wheel is installed on the output shaft of the screw driving motor. The number of driven wheels corresponds to that of the conveying screws one by one and is respectively connected to the ends of the respective conveying screws. The synchronous belt is tensioned between the driving wheel and the driven wheel.

[0015] By adopting the above technical solutions, by using the combination of the driving wheel, the driven wheel and the synchronous belt, the power of the screw driving motor can be efficiently and stably transmitted to each conveying screw. The driving wheel rotates driven by the motor output shaft, synchronously drives the driven wheel through the tensioned synchronous belt, and then makes each conveying screw operate. This transmission method avoids the slipping phenomenon during the power transmission process, ensures that the rotational speeds of the conveying screws are accurately consistent, and guarantees that the selecting needle pieces can be conveyed along the thread grooves of the conveying screws at a stable speed and rhythm, providing a reliable power guarantee for the orderly arrangement of the selecting needle pieces.

[0016] Furthermore, the selector blade supporting mechanism includes a tray for stacking a plurality of selector blades and a tray support provided on the platen for placing the tray. A tray steel bar is arranged in the tray along the length direction, a steel bar support plate is arranged in the tray along the width direction, and a selector blade baffle is arranged in the tray at a position far from the selector blade flipping mechanism.

[0017] By adopting the above technical solution, the tray provides an orderly storage space for the selector blades, facilitating the centralized management of a large number of selector blades. The tray steel bar arranged in the tray along the length direction can guide the selector blades to be neatly arranged, prevent them from moving randomly in the tray, and ensure the accurate position of the selector blades in the tray. The steel bar support plate arranged along the width direction plays a supporting role for the tray steel bar, enhancing the stability of the entire structure, further assisting the selector blades to maintain the correct posture in the tray, improving the regularity of the arrangement of the selector blades. The selector blade baffle is arranged in the tray at a position far from the selector blade flipping mechanism, which can effectively block the excessive movement of the selector blades in the tray and prevent the selector blades from slipping out of the tray.

[0018] Furthermore, the selector blade supporting mechanism further includes a convex stopper and a concave stopper for cooperating with the tray and limiting the selector blades.

[0019] By adopting the above technical solution, the selector blades have a certain curvature, and ordinary limiting methods may be difficult to accurately restrict their positions. The convex stopper and the concave stopper respectively fit the two end faces of the arranged selector blades, and can provide a more fitting and stable limiting effect according to the unique shape of the selector blades. Compared with a single planar block, this combination of specially designed stoppers can prevent the displacement of the selector blades in the tray along the length direction or the width direction in all directions, further ensuring the accuracy of the arrangement of the selector blades in the tray.

[0020] Furthermore, the selector blade frame includes a rack support installed on the platen, two guide columns symmetrically arranged on the rack support, a connecting side plate installed on the rack support and used for fixing the two guide columns, and a selector blade guide plate arranged at a position close to the upper end of the guide columns. Both of the two guide columns are perpendicular to the platen, and a hollow groove matching the length of the selector blade is left between the two guide columns. U-shaped sliding grooves for the ends of the selector blades to be inserted and slide are formed on both sides of the two guide columns close to each other along the length direction.

[0021] By adopting the above technical solution, the design of the needle selection piece rack body provides an accurate storage and retrieval method for the needle selection pieces. Two guide posts are arranged perpendicular to the table board, and a hollow groove matching the length of the needle selection piece is left between them, which is convenient for the placement and positioning of the needle selection piece. The U-shaped sliding grooves opened on the side surfaces of the guide posts close to each other can allow the end parts of the needle selection pieces to be stuck and slide, which not only ensures the stable storage of the needle selection pieces in the rack body, but also enables the needle selection pieces to move smoothly along the U-shaped sliding grooves when being pushed out by the pushing mechanism, ensuring that the posture of each retrieved needle selection piece is accurate and providing a good basis for subsequent conveying and arranging.

[0022] Furthermore, the material rack support is provided with a needle outlet control rod for supporting the needle selection piece on the side wall, and a needle outlet gap for a single needle selection piece to pass through and cooperate with the needle selection piece pushing mechanism is left between the upper side of the needle outlet control rod and the lower side of the guide post.

[0023] By adopting the above technical solution, the position of the needle outlet control rod is adjusted so that the needle outlet gap between its upper side and the lower side of the guide post only allows a single needle selection piece to pass through, avoiding the situation of multiple needle selection pieces falling simultaneously. When the needle selection piece pushing mechanism works, only the needle selection piece located at the needle outlet gap needs to be pushed out, ensuring that only one needle selection piece is pushed out by the needle selection piece pushing mechanism each time, and guaranteeing the accuracy and orderliness of the arrangement of the needle selection pieces. The needle outlet control rod supports both ends of the needle selection piece, making the needle selection piece more stable during the waiting process for being pushed, ensuring that the needle selection piece is always in the correct position of the needle outlet gap and waiting to be pushed out by the pushing mechanism.

[0024] Furthermore, the needle selection piece pushing mechanism includes a needle selection piece push block and a needle piece push-down air cylinder installed on the connecting side plate and used for driving the needle selection piece push block. The connecting side plate is fixedly connected with a cylinder support plate for installing the needle piece push-down air cylinder on the side wall, and the cylinder support plate is provided with a support plate reinforcing rib for cooperating with the connecting side plate.

[0025] By adopting the above technical solution, the needle selection piece pushing mechanism uses a needle piece push-down air cylinder to drive the needle selection piece push block, which can provide stable and efficient pushing power. The air cylinder is used as the power source to accurately control the movement of the needle selection piece push block, ensuring that the needle selection piece can be accurately pushed out from the needle outlet gap and enter the conveying mechanism. The cylinder support plate fixedly connected to the connecting side plate is used for installing the needle piece push-down air cylinder, and the support plate reinforcing rib on the cylinder support plate cooperates with the connecting side plate, effectively enhancing the overall structural strength.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Multiple needle selection piece holders are arranged at equal intervals. In cooperation with the needle selection piece pushing mechanism, different types of needle selection pieces can be quickly pushed out, and efficiently conveyed by the needle selection piece conveying mechanism, significantly shortening the needle arranging time. The conveying screw rod cooperates with the driving component to ensure that the needle selection pieces are stably and orderly conveyed along the screw rod, with stable power transmission, ensuring the speed and rhythm of the needle selection piece conveying, and improving the needle arranging efficiency from the overall process; 2. Each mechanism operates in coordination, effectively reducing the error rate of the needle selection piece arrangement. For example, the needle selection piece holder ensures the stable storage of the needle selection pieces and accurate needle ejection through the U-shaped sliding groove of the guide post and the needle ejection control rod; the needle selection piece conveying mechanism uses the thread groove and the needle selection guide bar to prevent the needle selection pieces from colliding, misaligning or falling during conveyance; the material tray steel bar, steel bar support plate, needle selection piece baffle, convex block and concave block of the needle selection piece supporting mechanism comprehensively ensure the arrangement accuracy of the needle selection pieces in the material tray, thereby improving the fabric texture quality; 3. The equipment structure is reasonably designed, and the installation and coordinated work of each component are good. For example, the auxiliary pushing component above the needle selection piece flipping mechanism ensures the coherence of the needle selection piece conveying process; the needle piece pushing cylinder of the needle selection piece pushing mechanism is installed on the cylinder support plate with a support plate reinforcing rib, enhancing the structural strength while facilitating installation and maintenance, reducing the maintenance cost and downtime, and improving the use efficiency and reliability of the equipment.

On the platen 2, there is a guide bar auxiliary support member 653 for fixing the extending portion 652. Between the limiting portion 651 and the flipping wheel piece 61, there is a flipping side guide plate 66.

[0049] A turnover mechanism housing 67 for covering the conveying screw 51 is installed on the platen 2, and the edge of the turnover mechanism housing 67 is located adjacent to the turnover wheel piece 61. An auxiliary pushing assembly 68 is installed on the upper side of the turnover mechanism housing 67 to push the selector blade stacked at the downstream position of the turnover wheel into the selector blade supporting mechanism 7.

[0050] The auxiliary pushing assembly 68 includes a needle pushing plate 681 and a needle pushing cylinder 682 for driving the needle pushing plate 681. The needle pushing cylinder 682 is fixedly connected to the turnover mechanism housing 67. The needle pushing plate 681 is located on one side of the selector blade supporting mechanism 7 and is installed at the end of the piston rod of the needle pushing cylinder 682. The turnover mechanism housing 67 has a pushing guiding inclined surface 671 on the top side for cooperating with the auxiliary pushing assembly 68. When selector blades are stacked above the turnover mechanism, the needle pushing cylinder 682 can act at an appropriate angle to push the needle pushing plate 681 to push the stacked selector blades into the selector blade supporting mechanism 7.

[0051] Refer to Figure 10 and Figure 11 , the selector blade supporting mechanism 7 includes a tray 71 for stacking selector blades, a tray support 71 for placing the tray 71, and a convex stopper 73 and a concave stopper 74 that match the two side surfaces of the selector blade. A steel bar 71 of the tray 71 is provided along the length direction inside the tray 71 to guide the selector blades to be neatly arranged. A steel bar support plate 712 is provided along the width direction inside the tray 71 to support the steel bar 71 of the tray 71. A selector blade baffle 713 is provided on one side of the tray 71 away from the selector blade turnover mechanism 6 to prevent the selector blades from moving excessively.

[0052] The convex stopper 73 and the concave stopper 74 conform to the two end faces of the selector blade according to the shape of the selector blade, and limit the position in all directions to ensure that the selector blades are closely arranged. Two first steps 731 for abutting against the side wall of the selector blade are integrally connected to one side of the convex stopper 73 close to the selector blade frame 3, and the two first steps 731 are symmetrically arranged at positions close to the two ends of the convex stopper 73.

Two second steps 741 for abutting against the side wall of the selector blade are integrally connected to one side of the concave stopper 74 away from the selector blade frame 3, and the two second steps 741 are symmetrically arranged at positions close to the two ends of the concave stopper 74. Both of the two second steps 741 have an abutting inner inclined surface 742 for abutting against the selector blade on the side away from the selector blade frame 3.

[0053] The implementation principle of a needle selection piece rowing machine according to an embodiment of the present application is as follows: Needle selection pieces of different models are stored in respective needle selection piece racks 3. The needle selection pieces are placed in the hollow grooves 321 between the guide posts 32, and the ends are snapped into the U-shaped sliding grooves 322. At the side wall of the rack support 31, the needle outlet control rod 311 and the lower side of the guide post 32 leave a needle outlet gap 312, which only allows a single needle selection piece. In the needle selection piece pushing mechanism 4, the needle piece pushing cylinder 42 pushes the needle selection piece push block 41, driving the push needle support rod 412 to push the needle selection piece at the needle outlet gap 312 to the needle selection piece conveying mechanism 5.

[0054] In the needle selection piece conveying mechanism 5, the conveying screw 51 is rotatably connected to the table board 2 through the screw support seat 511. The outer wall thread groove 512 receives the needle selection piece, and the two side needle selection guide bars 53 limit the displacement of the needle selection piece. In the driving assembly 52, the screw driving motor 524 drives the driving wheel 521, and drives the driven wheel 522 corresponding to the conveying screw 51 through the synchronous belt 523, driving the conveying screw 51 to rotate to achieve stable conveying of the needle selection piece.

[0055] The needle selection piece flipping mechanism 6 is located between the conveying and supporting mechanisms. The flipping core shaft 62 is fixed at the center of the flipping wheel piece 61, and the flipping driving member 63 provides power. The circumferential ratchet teeth 611 of the flipping wheel piece 61 drive the needle selection piece to flip. The flipping guide bar 65, the guide bar auxiliary support 653 and the flipping side guide plate 66 ensure that the needle selection piece is accurately flipped and connected to the supporting mechanism. When there are needle selection pieces stacked above the flipping mechanism, the auxiliary pushing assembly 68 on the flipping mechanism housing 67, that is, the push needle cylinder 682 pushes the push needle plate 681, and pushes the needle selection piece along the pushing guide inclined surface 671 into the needle selection piece supporting mechanism 7.

[0056] The needle selection piece supporting mechanism 7 includes a material tray 71, a material tray 71 support, a convex stop block 73 and a concave stop block 74. The steel bars in the material tray 71 guide the arrangement of the needle selection pieces and are supported by the steel bar support plate 712. The needle selection piece baffle 713 prevents excessive movement. The convex stop block 73 and the concave stop block 74 are designed according to the shape of the needle selection piece, and fit the two end faces of the needle selection piece through the first step 731, the abutting outer inclined surface 732, the second step 741 and the abutting inner inclined surface 742, and perform all-round limiting, so that the needle selection pieces are closely arranged in groups in the material tray 71 to complete automatic needle rowing.

[0057] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
