Technical Field
[0001] The utility model relates to the technical field of sewing equipment, in particular to a sewing machine needle management system. Background Art
[0002] In the current sewing industry, factories generally implement strict needle management processes to ensure the smooth progress of the production process and the safety of workers. This process usually includes the issuance, registration, and recovery of broken needles, and these tasks are mostly performed by specialized personnel. However, manual management is inefficient, manual registration and issuance are prone to errors, and production quality accidents are difficult to trace. In order to further optimize the needle management process and improve management efficiency, a variety of technical solutions have been proposed and applied in actual production. For example, patent CN202322335867.X discloses a sewing machine needle management cabinet, which basically realizes the automated management of machine needles. This management method has significant shortcomings: the operation of obtaining machine needles is cumbersome and inefficient. When the demand for machine needles is more frequent, managers need to frequently perform needle replenishment operations, which undoubtedly reduces overall work efficiency.
[0003] To address these issues, patent CN114182444B proposes a needle removal device for sewing machine needle management systems based on the improved patent. This device uses a set of X and Y mechanisms to control the needle removal mechanism to a specified position, which then retrieves or releases the needle. While this solution improves the automation level of needle management to a certain extent, its structure is relatively complex. Utility Model Content
[0004] In order to overcome at least one of the above-mentioned defects of the prior art, the present invention provides a sewing machine needle management system that can solve the problem of frequent needle placement, and the overall management system is convenient and fast in needle removal and replenishment, and intelligent management helps save manpower.
[0005] The technical solution adopted by the present invention to solve the problem is:
[0006] : A sewing machine needle management system comprises: a workbench; a rotating mechanism, the rotating mechanism comprising a main motor, a synchronous belt and at least two synchronous wheels, the main motor drives the synchronous wheels to rotate, and the synchronous belt is wound between at least two of the synchronous wheels; a sliding track, the sliding track is arranged on the workbench parallel to the synchronous belt, and the sliding track includes a needle placing position and a needle taking position; a storage needle box mechanism, the storage needle box mechanism is slidably arranged on the sliding track and moves synchronously with the synchronous belt; a needle out detection module, the needle out detection module is adjacent to the needle taking position; the storage needle box mechanism comprises a sliding seat sliding along the sliding track and a storage needle box assembled on the sliding seat, the storage needle box comprises a needle box housing, a needle out push plate and a linkage mechanism, the needle box housing is provided with a needle placing inlet for adding needles at the needle placing position and a needle taking outlet for removing needles at the needle taking position, when the needle box housing is at the needle taking position, the linkage mechanism pushes the needle out push plate from the inner part of the needle box housing to the outside of the needle taking outlet.
[0007] By adopting the above solution, the synchronous wheel and synchronous belt driven by the main motor, as well as the sliding track parallel to the synchronous belt, realize the automatic movement of the storage needle box mechanism. This design can simplify the operation process of picking up the machine needle and improve operational efficiency; the storage needle box mechanism can slide along the sliding track and move between the needle placement position and the needle removal position. When in the needle removal position, the linkage mechanism pushes the needle ejection push plate from the inner part of the needle box housing to the needle removal outlet, realizing the automatic removal of the needle. The design of the storage needle box effectively reduces the frequent need for management personnel to replenish needles and improves work efficiency; the overall design is relatively simple, avoiding overly complex structures, thereby reducing maintenance costs and difficulty of use.
[0008] Furthermore, the linkage mechanism includes a rotating lever, a power lever, a transmission lever and a reset member. The transmission lever passes through the middle of the rotating lever and is connected to the power lever. One end of the rotating lever is rotatably connected to the needle ejection push plate. The other end of the rotating lever is provided with a hook-shaped portion connected to the reset member. The reset member controls the hook-shaped portion to make the rotating lever rotate with the transmission lever as the axis, thereby resetting the needle ejection push plate into the needle box housing.
[0009] By adopting this solution, the linkage mechanism precisely controls the ejection and repositioning of the needle ejection push plate, allowing employees to easily access needles and improving operational convenience. Because the linkage mechanism precisely controls the movement of the needle ejection push plate, it ensures that only one needle is ejected at a time, avoiding the problem of ejecting multiple needles simultaneously. Furthermore, this mechanism design allows needles to be stored in batches in the needle storage box, improving needle placement efficiency.
[0010] Further, a rotating shaft pull rod is provided on the side of the needle pushing plate facing the inside of the needle box housing. A rotating shaft groove is provided at one end of the rotating lever away from the hook-shaped portion, and the rotating shaft pull rod rotates within the rotating shaft groove.
[0011] By adopting the above scheme, when the power lever drives the rotating lever to rotate through the transmission rod, the rotating shaft groove of the rotating lever will drive the rotating shaft pull rod on the needle pushing plate to rotate together. After the power source is removed, the reset member will act on the hook-shaped portion of the rotating lever to make the rotating lever rotate in the reverse direction; this makes the connection between the needle pushing plate and the rotating lever more stable and reliable, capable of withstanding greater thrust and tensile forces, and not prone to loosening or falling off. This makes the mechanism operate more smoothly and steadily during the movement process, reduces the situation of jamming and shaking, and improves the accuracy and efficiency of picking up the machine needle.
[0012] Further, a push plate stopper is also provided outside the needle box housing. The push plate stopper includes a connecting section, an extending section, and a blocking section that are integrally bent. The connecting section is connected to the needle box housing, the extending section extends outward from the needle taking outlet, and the blocking section faces the needle taking outlet to block the needle taking outlet.
[0013] By adopting the above scheme, the integrally bent connecting section, extending section, and blocking section not only ensure the stability of the components, but also make the push plate stopper closely fit on the outside of the needle box housing; when the needle pushing plate is pushed out from the inside of the needle box housing under the action of the linkage mechanism, there will be a situation where two or more machine needles overlap, which will cause the needle pushing plate to provide elastic potential energy to the extra machine needles when it is pushed out. When the two machine needles are completely separated, there is a chance that the machine needle will bounce or fly out from the needle taking outlet, and the blocking section can effectively block the flying needle or the jumping needle, so that the machine needle can fall back onto the needle pushing plate.
[0014] Further, the needle taking position further includes a power mechanism, and the power mechanism includes: a power device housing; a lever motor, which is assembled in the power device housing; a lever execution mechanism, which is drivingly connected to the lever motor to drive the power lever to rotate; and a lever position sensor, which is used to judge whether the lever drives the power lever to rotate in place.
[0015] By adopting the above scheme, the lever position sensor monitors the position of the lever execution mechanism in real time to ensure that the lever can accurately drive the power lever to rotate in place, so as to ensure that the needle pushing plate can stably stay at the needle taking outlet. The design of the power mechanism enables the needle taking action to be automated, improves the work efficiency and accuracy, and the real-time monitoring of the lever position sensor ensures the stability and reliability of the needle taking action.
[0016] Further, the needle taking position further includes a vibration mechanism, and the vibration mechanism includes: a vibration motor; a vibrating member, the vibrating member is drivingly connected to the vibration motor, and when the storage needle box mechanism is located at the needle taking position, the vibrating member abuts against the needle box housing.
[0017] By adopting the above scheme, the vibration of the vibration motor is transmitted to the needle box housing through the vibrating member, causing the needle box housing to generate a slight vibration, so that the needles in the needle box housing are oscillated and reset, keeping the needles parallelly arranged, and at the same time, the whole can be oscillated to one side of the needle box housing to prepare for needle taking.
[0018] Further, the needle taking position and / or the needle placing position further includes a positioning mechanism, the storage needle box mechanism is provided with a clamping groove, and the positioning mechanism includes: a rotating member; a positioning rod, the positioning rod is assembled at the end of the rotating member; a positioning drive motor, the positioning drive motor is connected to the rotating member and is used to drive the rotating member to rotate so as to clamp the positioning rod into the clamping groove.
[0019] By adopting the above scheme, the positioning mechanism ensures the stability and accuracy of the storage needle box mechanism at the needle taking position, thereby ensuring that the machine needles can be smoothly and accurately taken out. The positioning mechanism effectively limits the position of the storage needle box mechanism by clamping into the clamping groove, thereby ensuring the accuracy of needle taking and enhancing the stability of the whole mechanism.
[0020] Further, the positioning mechanism further includes a grating positioning mechanism, and the grating positioning mechanism includes: a rotating piece, the rotating piece rotates synchronously with the rotating member; a positioning disk, the positioning disk is provided with a first grating position and a second grating position; when the rotating piece is located at the first grating position, the positioning rod is clamped with the clamping groove, and when the rotating piece is located at the second grating position, the positioning rod is released from the clamping groove.
[0021] By adopting the above scheme, as the rotating piece rotates, when it reaches the first grating position, the grating sensor detects this change and sends a signal to the control system. After receiving the signal, the control system confirms that the positioning rod has been accurately clamped into the clamping groove, and at this time, the storage needle box mechanism is stably positioned at the needle taking position; after the needle taking operation is completed, the positioning drive motor is started again to drive the rotating member and the rotating piece to rotate in the reverse direction. When the rotating piece reaches the second grating position, the grating sensor sends a signal again. After receiving the signal, the control system confirms that the positioning rod has been released from the clamping groove, and at this time, the storage needle box mechanism can move to other positions; through the precise detection of the position of the rotating piece by the grating sensor, the grating positioning mechanism can ensure that the clamping and releasing operations of the positioning rod and the clamping groove are accurate and error-free. The design of the grating positioning mechanism avoids the problem of inaccurate positioning caused by mechanical wear or error, and improves the reliability and stability of the whole mechanism.
[0022] Furthermore, the sliding seat includes: a sliding plate provided with an assembly position thereon; an inclined base assembled within the assembly position, the inclined base having an inclined surface, and the storage needle box being assembled on the inclined surface so that the needle pushing plate is inclined with respect to the sliding plate; an inner pulley assembled at the bottom of the sliding plate and sliding on the inner side of the sliding track; and an outer pulley assembled at the bottom of the sliding plate and sliding on the outer side of the sliding track.
[0023] By adopting the above scheme, the arrangement of the inner pulley and the outer pulley enables the sliding seat to move smoothly and accurately on the sliding track, ensuring the smooth progress of the needle-taking operation and also improving the operating efficiency and stability of the entire needle-taking and placing mechanism: the inclined surface design of the inclined base enables the storage needle box to maintain a certain inclination angle during the needle-taking process. This design helps the sewing needles to slide out more smoothly under the action of gravity, reducing the resistance and friction during the needle-taking process and improving the needle-taking efficiency.
[0024] In summary, a sewing machine needle management system provided by the present utility model has the following technical effects:
[0025] 1. Through the synchronous pulley and synchronous belt driven by the main motor, and the sliding track parallel to the synchronous belt, the system realizes the automatic movement of the storage needle box mechanism. This design greatly simplifies the operation process of receiving and adding sewing needles, making the entire needle-taking process more smooth and efficient;
[0026] 2. The storage needle box mechanism can move between the needle-placement position and the needle-taking position along the sliding track. When located at the needle-taking position, the linkage mechanism will automatically push the needle pushing plate out of the needle box housing, thereby completing the automatic needle-taking of the sewing needles. This design reduces the steps of manual operation, enabling the management personnel to more easily complete the management task of the sewing needles;
[0027] 3. Since the system realizes automatic movement and automatic needle-taking, the difficulty of the management personnel in replenishing and managing the sewing needles can be greatly reduced. This not only improves the work efficiency but also reduces the needle management problems caused by human operation errors;
[0028] 4. The overall design is relatively simple, avoiding overly complex structures. This not only reduces the maintenance cost of the system but also makes the system easier to use and maintain. Through automatic management, the system can reduce the chance of manual contact with the sewing needles, thereby reducing the risks of safety and production quality accidents caused by improper operation.

[0040] In order to facilitate the understanding of the embodiments of the present invention, the following will be further explained with reference to specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present invention.
[0041] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.
[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.
[0043] Refer to Embodiment 1 of the present utility model Figures 1-9As shown, a sewing machine needle management system is disclosed, which includes a workbench 8, a rotating mechanism 9, a sliding track 1, a needle detection module 10, and a storage needle box mechanism 2. The rotating mechanism 9 includes a main motor 91, a synchronous belt 92, and at least two synchronous pulleys 93. The main motor 91 drives the synchronous pulleys 93 to rotate, and the synchronous belt 92 is wound between at least two synchronous pulleys 93. The sliding track 1 is arranged on the workbench 8 parallel to the synchronous belt 92, and the storage needle box mechanism 2 moves synchronously with the synchronous belt 92. The workbench 8 provides a stable working environment and necessary operating space, and is arranged on the workbench 8 parallel to the synchronous belt 92 to guide the sliding of the storage needle box mechanism 2. The design of the sliding track 1 ensures the stability and accuracy of the storage needle box mechanism 2 during movement, realizes the automatic management of sewing machine needles, is applicable to the sewing machine needles of various automatic sewing equipment, can meet the sewing machine needles with different sewing requirements, and improves the quality and efficiency of sewing machine needle control. In order to be more conducive to intelligent operation, a controller can also be added to control the drive of each module through the controller, saving manpower. The sliding track 1 includes a needle placement position 11 and a needle taking position 12. The storage needle box mechanism 2 slides on the sliding track 1 and switches between the needle placement position 11 and the needle taking position 12. The storage needle box mechanism 2 includes a sliding seat 21 sliding along the sliding track 1 and a storage needle box 3 assembled on the sliding seat 21. The storage needle box 3 includes a needle box housing 31, a needle pushing plate 32, and a linkage mechanism 33. The needle box housing 31 is provided with a needle placement inlet 311 for adding needles at the needle placement position 11 and a needle taking outlet 312 for taking out needles at the needle taking position 12. When the needle box housing 31 is located at the needle taking position 12, the linkage mechanism 33 partially pushes the needle pushing plate 32 out of the needle taking outlet 312 outside the needle box housing 31. The needle pushing plate 32 is provided with a needle groove 321 for accommodating sewing machine needles. Specifically, the depth of the needle groove 321 can be between one time and two times the needle diameter. Preferably, the depth of the needle groove 321 is slightly greater than one time the needle diameter. At least one end of the needle groove 321 is open, and the open end of the needle groove 321 is inclined downward so that the needles in the needle groove 321 slide out under gravity when the needle pushing plate 32 is pushed out of the needle box housing 31. Optionally, the edge of the needle groove 321 is provided with a sliding out portion 322 for facilitating the sliding out of the needles. The sliding out portion 322 is preferably a chamfer or an inclined surface. In this embodiment 1, both sides of the needle groove 321 are open to form an opening 323. This picking and placing mechanism realizes the rapid placement and taking out of sewing machine needles through the combination of the sliding track 1 and the storage needle box mechanism 2. The storage needle box mechanism 2 includes a sliding seat 21 sliding along the sliding track 1 and a storage needle box 3 assembled thereon. The needle taking detection module 10 is arranged adjacent to the needle taking position 12. The needle taking detection module 10 can detect whether a needle is taken out and feedback it to the controller.
[0044] It should be noted that multiple storage needle box mechanisms 2 can be arranged on each sliding rail to store sewing needles of different specifications and sizes.
[0045] In some embodiments, in order to accurately distinguish each storage needle box mechanism 2, sensors can be arranged on the sliding rail 1 and / or each storage needle box mechanism 2 to identify the storage needle box 3 of each said storage needle box mechanism 2, so that the corresponding storage needle box can be quickly located and found through the controller and conveyed to the needle placing position 11 and the needle taking position 12.
[0046] In a specific embodiment, the linkage mechanism 33 includes a rotating lever 331, a power lever 332, a transmission rod 333 and a reset member 334. The transmission rod 333 passes through the middle of the rotating lever 331 and is connected to the power lever 332. One end of the rotating lever 331 is rotatably connected to the needle pushing plate 32. A hook-shaped portion 3311 connected to the reset member 334 is arranged at the other end of the rotating lever 331. The reset member 334 controls the hook-shaped portion 3311 to make the rotating lever 331 rotate with the transmission rod 333 as the axis, so that the needle pushing plate 32 is reset into the needle box housing 31. Preferably, the reset member 334 is a tension spring. In other embodiments, the tension spring can also be changed to a spring or others, as long as it can ensure that the needle pushing plate 32 is smoothly reset into the needle box housing 31. The linkage mechanism 33 enables employees to easily obtain sewing needles by precisely controlling the pushing and resetting of the needle pushing plate 32, improving the operation convenience; since the linkage mechanism 33 can precisely control the movement of the needle pushing plate 32 and cooperate with the sliding portion 322 of the needle groove 321, it can ensure that only one sewing needle is pushed out each time, avoiding the problem of pushing out multiple needles at the same time. At the same time, the design of this mechanism enables sewing needles to be placed in the storage needle box 3 in batches, improving the needle placing efficiency. In order to facilitate the sewing needles in the storage needle box 3 to all approach the needle taking outlet 312 side, the whole storage needle box 3 needs to be inclined obliquely downward towards the needle taking outlet 312 side, which is more conducive to the sewing needles being pushed out.
[0047] In the present Embodiment 1, a rotating shaft pull rod 324 is provided on one side of the needle pushing plate 32 facing the inside of the needle box housing 31. A rotating shaft groove 3312 is provided at one end of the rotating lever 331 away from the hook-shaped portion. The rotating shaft pull rod 324 rotates within the rotating shaft groove 3312. When the power lever 332 drives the rotating lever 331 to rotate through the transmission rod 333, the rotating shaft groove 3312 of the rotating lever 331 will drive the rotating shaft pull rod 324 on the needle pushing plate 32 to rotate together. After the power source is removed, the reset member 334 acts on the hook-shaped portion of the rotating lever 331 to rotate the rotating lever 331 in the reverse direction; this makes the connection between the needle pushing plate 32 and the rotating lever 331 more stable and reliable, capable of withstanding greater thrust and pulling forces, and not easily loosening or falling off, making the mechanism more smooth and stable during operation, reducing jamming and jitter, and improving the accuracy and efficiency of picking up the machine needle. In other embodiments, the transmission structure between the needle pushing plate 32 and the rotating lever 331 is not specifically limited. Similarly, the linkage mechanism 33 can also be replaced with other different structures as long as it can achieve the normal pushing out and pulling back of the needle pushing plate 32.
[0048] To prevent the needle pushing plate 32 from completely sliding out from the needle taking outlet 312, in some embodiments, optionally, a push plate stopper 313 is further provided outside the needle box housing 31. The push plate stopper 313 includes an integrally bent connecting section 3131, an extending section 3132, and a blocking section 3133. The connecting section 3131 is connected to the needle box housing 31. The extending section 3132 extends outward from the needle taking outlet 312. The blocking section 3133 faces the needle taking outlet 312 to block the needle taking outlet 312. With this setting, the integrally bent connecting section 3131, extending section 3132, and blocking section 3133 not only ensure the stability of the components but also enable the push plate stopper 313 to closely fit on the outside of the needle box housing 31; when the needle pushing plate 32 is pushed out from the inside of the needle box housing 31 under the action of the linkage mechanism 33, there will be a situation where more than two machine needles overlap, which will cause the needle pushing plate 32 to provide elastic potential energy to the extra machine needles when being pushed out. When the two machine needles are completely separated, there is a chance that the machine needle will bounce or fly out from the needle taking outlet 312, while the blocking section 3133 can effectively block the flying or bouncing needle, enabling the machine needle to fall back onto the needle pushing plate 32.
[0049] In some embodiments, in order to realize the intelligent pushing out of the needle ejection push plate 32, optionally, the needle removal position 12 also includes a power mechanism 4, and the power mechanism 4 includes a power device housing 41, a lever motor 42, a lever actuator 43 and a lever position sensor 44. The lever motor 42 is assembled in the power device housing 41, and the lever actuator 43 is driven and connected to the lever motor 42 to drive the power lever 332 to rotate. The lever position sensor 44 is used to determine whether the lever actuator 43 drives the power lever 332 to rotate into place. The lever position sensor 44 monitors the position of the lever actuator 43 in real time to ensure that the lever actuator 43 can accurately drive the power lever 332 to rotate into place, thereby ensuring that the needle ejection push plate 32 can stably stay at the needle removal outlet 312. The design of the power mechanism 4 enables the needle removal action to be automated, thereby improving work efficiency and accuracy. The real-time monitoring of the lever position sensor 44 ensures the stability and reliability of the needle removal action. In this embodiment 1, the output end of the lever motor 42 is connected to the lever actuator 43, and the lever actuator 43 includes a rotating arm 431. The end of the rotating arm 431 is provided with a lever block 432. The structure of the lever block 432 is not specifically limited. The lever block 432 in this embodiment 1 is columnar. The lever block 432 can move the power lever 332 of the storage needle box 3 located at the needle removal position 12 under the rotation drive of the rotating arm 431.
[0050] In order to ensure that the machine needle can smoothly fall into the needle groove 321 on the needle outlet push plate 32, in some embodiments, a vibration mechanism 5 is provided in the needle removal position 12, and the vibration mechanism 5 includes a vibration motor 51 and a vibration member 52. The vibration member 52 is driven and connected to the vibration motor 51. When the needle storage box mechanism 2 is located at the needle removal position 12, the vibration member 52 is against the needle box housing 31. Preferably, the vibration member 52 is an oscillation disk driven by the vibration motor 51. The vibration of the vibration motor 51 is transmitted to the needle box housing 31 through the vibration member 52, causing the needle box housing 31 to produce a slight vibration, thereby causing the machine needle in the needle box housing 31 to vibrate and reset. Since the needle box housing 31 itself is tilted downward toward the needle removal outlet 312, the machine needle can remain parallel to the needle groove 321 and the needle removal outlet 312 on the needle outlet push plate 32, thereby ensuring the parallel placement of all needle bodies, and can be vibrated as a whole to one side of the needle box housing 31 to prepare for removing the needle from the needle removal outlet 312.
[0051] In the present Embodiment 1, the sliding seat 21 includes a sliding plate 211, an inclined base 212, inner pulleys 213 and outer pulleys 214. An assembly position 2111 is provided on the sliding plate 211, and the inclined base 212 is assembled within the assembly position 2111. The inclined base 212 has an inclined surface 2121, and the storage needle box 3 is assembled on the inclined surface 2121, so that the needle pushing plate 32 is inclined with respect to the sliding plate 211. The inner pulleys 213 are assembled at the bottom of the sliding plate 211 and slide inside the sliding track 1, and the outer pulleys 214 are assembled at the bottom of the sliding plate 211 and slide outside the sliding track 1. Preferably, a convex edge or a chute for preventing derailment is provided between the inner side of the sliding track 1 and the inner pulley 213. Similarly, a convex edge or a chute for preventing derailment is provided between the outer side of the sliding track 1 and the outer pulley 214. Preferably, two inner pulleys 213 and two outer pulleys 214 are provided. With the structure of the convex edge or the chute, the sliding of the sliding seat 21 on the sliding track 1 can be kept stable. The setting of the inner pulleys 213 and the outer pulleys 214 enables the sliding seat 21 to move smoothly and accurately on the sliding track 1, ensuring the smooth progress of the needle taking operation and improving the operation efficiency and stability of the entire picking and placing mechanism. The inclined base 212 is designed as a right triangular prism structure in the present Embodiment 1. The design of the inclined surface 2121 on its top surface enables the storage needle box 3 to maintain a certain inclination angle during the needle taking process. This design helps the machine needle to slide more smoothly under the action of gravity and slide towards the needle taking outlet 312. Moreover, the needle pushing plate 32 is also inclined, reducing the resistance and friction during the needle taking process and improving the needle taking efficiency. Optionally, the included angle range between the inclined surface 2121 of the right triangular prism and the sliding seat 21 is preferably 30-90°, which can ensure that the machine needle can smoothly slide out from the opening 323 at the end of the chute.
[0052] In some embodiments, in order to ensure that the storage needle cartridge mechanism 2 can be stationary at the same position when picking up or placing needles, positioning mechanisms 6 are provided at both the needle picking position 12 and the needle placing position 11. The storage needle cartridge mechanism 2 is provided with a clamping groove 2112. Optionally, the clamping groove 2112 is located on the side of the sliding plate 211 away from the sliding track 1. The positioning mechanism 6 includes a rotating member 61, a positioning rod 62, and a positioning drive motor 63. The positioning rod 62 is assembled at the end of the rotating member 61. The positioning drive motor 63 is connected to the rotating member 61 and is used to drive the rotating member 61 to rotate so as to engage the positioning rod 62 with the clamping groove 2112. Preferably, a chamfer or a slope is provided on the edge of the clamping groove 2112. When there is a slight gap between the stop position of the storage needle cartridge mechanism 2 and the needle picking position 12, the chamfer or the slope is beneficial for the positioning rod 62 to be engaged with the clamping groove 2112, thereby achieving a calibration effect. With this setting, the positioning mechanism 6 ensures the stability and accuracy of the storage needle cartridge mechanism 2 at the needle picking position 12, thus ensuring that the machine needle can be smoothly and accurately taken out. The positioning mechanism 6 effectively restricts the position of the storage needle cartridge mechanism 2 by engaging with the clamping groove 2112, thereby ensuring the accuracy of needle picking and enhancing the stability of the entire mechanism.
[0053] Preferably, the positioning mechanism 6 further includes a grating positioning mechanism 64. The grating positioning mechanism 64 includes a rotating piece 641 and a positioning disk 642. The rotating piece 641 rotates synchronously with the rotating member 61. The positioning disk 642 is provided with a first grating position 643 and a second grating position 644. When the rotating piece 641 is located at the first grating position 643, the positioning rod 62 is engaged with the clamping groove 2112. When the rotating piece 641 is located at the second grating position 644, the positioning rod 62 is disengaged from the clamping groove 2112. As the rotating piece 641 rotates, when it reaches the first grating position 643, the grating sensor detects this change and sends a signal to the control system. After receiving the signal, the control system confirms that the positioning rod 62 has been accurately engaged with the clamping groove 2112. At this time, the storage needle cartridge mechanism 2 is stably positioned at the needle picking position 12. After the needle picking operation is completed, the positioning drive motor 63 is started again to drive the rotating member 61 and the rotating piece 641 to rotate in the reverse direction. When the rotating piece 641 reaches the second grating position 644, the grating sensor sends a signal again. After receiving the signal, the control system confirms that the positioning rod 6 has been released from the clamping groove 2112. At this time, the storage needle cartridge mechanism 2 can move to other positions. Through the precise detection of the position of the rotating piece 641 by the grating sensor, the grating positioning mechanism 64 can ensure that the engagement and disengagement operations between the positioning rod 62 and the clamping groove 2112 are accurate and error-free. The design of the grating positioning mechanism 64 avoids the problem of inaccurate positioning caused by mechanical wear or errors, and improves the reliability and stability of the entire mechanism.
[0054] In the first embodiment, a needle adding control mechanism 7 is provided at the needle placing position 11. The needle adding control mechanism 7 includes a needle adding control board 71, a supplementary needle chamber door 72, a push rod mechanism 73, and a chamber door position sensor 74. The needle placing inlet 311 is arranged on the top surface of the storage needle box 3. The needle adding control board 71 faces the needle placing inlet 311 of the needle box housing 31 at the needle placing position 11. When it is necessary to supplement machine needles, the storage needle box mechanism 2 slides to the needle placing position 11. At this time, the supplementary needle chamber door 72 faces the needle placing inlet 311. The push rod mechanism 73 drives the supplementary needle chamber door 72 to act under the action of a motor, and judges whether the supplementary needle chamber door 72 is fully opened or closed according to the chamber door position sensor 74. Specifically, the needle adding control board 71 is provided with a needle placing opening 711. The size of the needle placing opening 711 is equivalent to the size of the needle placing device of the relevant sewing equipment, and multiple needles can be placed at the same time. In the first embodiment, 100-200 needles can be placed at the same time. The supplementary needle chamber door 72 is located below the needle placing opening 711, and the needle placing opening 711 is opened or closed by the push of the push rod mechanism 73. The chamber door position sensor 74 can detect the position of the supplementary needle chamber door 72 currently controlled by the push rod mechanism 73. In other embodiments, the push rod mechanism 73 can be replaced with a gear and rack structure or a structure similar to a rolling shutter door.
[0055] When taking needles, the controller issues an instruction for the specification and model of the machine needles to be taken. According to the position information stored in the controller and the sensors, the position of the corresponding storage needle box 3 is determined. The main motor 91 starts to rotate under the control of the controller, drives the sliding seat 21 and the storage needle box 3 to operate, and controls the corresponding storage needle box 3 to operate to the needle taking position 12. After the storage needle box 3 arrives, the positioning mechanism 6 acts to lock the sliding seat 21 and the storage needle box 3. Then, after the vibration mechanism vibrates for a period of time, the power mechanism 4 drives the power lever 332 on the storage needle box 3 to act, drives the needle pushing plate 32 to push out the machine needles, and finally the needle taking detection module 10 feeds back the needle taking situation to the controller. When placing needles, the controller issues an instruction for the specification and model of the machine needles to be taken. According to the position information stored in the controller and the sensors, the position of the corresponding storage needle box 3 is determined. The main motor 91 starts to rotate under the control of the controller, drives the sliding seat 21 and the storage needle box 3 to operate, and controls the corresponding storage needle box 3 to operate to the needle placing position 11. After the storage needle box 3 arrives, the positioning mechanism 6 acts to lock the sliding seat 21 and the storage needle box 3. Then, the supplementary needle chamber door 72 is opened, and the corresponding machine needles are placed.
[0056] In summary, a sewing machine needle management system provided by the present utility model has the following technical effects:
[0057] 1. Through the synchronous pulley 93 driven by the main motor 91, the synchronous belt 92, and the sliding track 1 parallel to the synchronous belt 92, the system realizes the automatic movement of the storage needle box mechanism 2. This design greatly simplifies the operation process of picking up and adding machine needles, making the entire needle picking process smoother and more efficient;
[0058] 2. The storage needle box mechanism 2 can move along the sliding track 1 between the needle placing position 11 and the needle picking position 12. When it is at the needle picking position 12, the linkage mechanism 33 will automatically push the needle pushing plate 32 out of the needle box housing 31, thus completing the automatic needle output of the machine needle. This design reduces the steps of manual operation, enabling the management personnel to more easily complete the management task of the machine needle;
[0059] 3. Since the system realizes automatic movement and automatic needle output, it can greatly reduce the difficulty for the management personnel to replenish and manage the machine needles. This not only improves work efficiency but also reduces the problems of machine needle management caused by human operation errors;
[0060] 4. The overall design is relatively simple, avoiding overly complex structures. This not only reduces the maintenance cost of the system but also makes the system easier to use and maintain. Through automatic management, the system can reduce the chance of manual contact with the machine needle, thereby reducing the risks of safety and production quality accidents caused by improper operation.
