Description

Technical Field

[0001] The utility model relates to the field of coil embroidery machines, especially a coil embroidery machine with a color-changing material storage device. Background Art

[0002] Referring to the Chinese invention patent application with the publication number CN117107453A, a color-changing material storage device for a coil embroidery tape reel assembly is provided above the head of the coil embroidery machine, and the color change of multi-color coil embroidery is realized by replacing the tape reel assembly. The color-changing material storage device includes a guide rail and a material rack that can slide relative to the guide rail. Among them, the material rack includes a turntable, and multiple groups of positioning arms for installing the tape reel assembly are circumferentially arranged on the turntable. Multiple tape reel assemblies are axially installed on the positioning arms. By horizontally sliding the material rack, one of the tape reel assemblies on one of the positioning arms is made to correspond to the position of the manipulator. The manipulator grabs the tape reel assembly on the positioning arm and installs it on the head of the embroidery machine, or grabs the tape reel assembly on the head of the embroidery machine and installs it on the positioning arm.

[0003] However, for the coil embroidery machine in the above solution, on the one hand, multiple groups of tape reel assemblies are horizontally arranged on the positioning arms, resulting in a large width of the color-changing material storage device; on the other hand, in order to realize the color-changing material storage of the tape reel assembly, the material rack needs to move horizontally, resulting in the need to reserve additional space for the horizontal movement of the color-changing material storage device on the coil embroidery machine. In this way, the distance between adjacent coil embroidery heads on the coil embroidery machine needs to be left very large, resulting in a significant reduction in the density of the coil embroidery heads on the coil embroidery machine with the same floor area compared to the density of the embroidery heads on the ordinary embroidery machine. Since the working speed of the head is difficult to further increase, the output of the coil embroidery machine is much lower than that of the ordinary embroidery machine, and thus the price of the coil embroidery products remains high. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and propose a coil embroidery machine to solve various drawbacks caused by the large width of the color-changing material storage device and the need for horizontal movement on the existing coil embroidery machine.

[0005] To achieve the above technical objectives, a coil embroidery machine proposed by the utility model includes a frame, multiple coil embroidery heads fixed on the frame, multiple manipulators, and multiple color-changing material storage devices. The coil embroidery heads, the manipulators, and the color-changing material storage devices correspond one by one. The coil embroidery heads are arranged below the color-changing material storage devices. Multiple tape reel assemblies are installed on each color-changing material storage device. The manipulator is used to grab the tape reel assembly on the color-changing material storage device and install it on the coil embroidery head, or grab the tape reel assembly on the coil embroidery head and install it on the color-changing material storage device.

[0010] The turntable rotates in the first direction to push the check swing rod away from the blocking portion, so that the check swing rod is in the open state, thus preventing the check swing rod from restricting the rotation of the turntable. The check spring acts on the check swing rod to make the check swing rod tend to return to the check state. In the check state, the check swing rod abuts against the blocking portion to limit the rotation of the turntable in the second direction.

[0011] Preferably, the check component further includes a check slider, a check mounting seat, and a check adjusting block. The check slider is detachably mounted on the check swing rod.

[0015] Preferably, the material rack includes a longitudinally extending side panel, and the fixing frame is provided with a longitudinally extending mating groove, in which at least part of the side panel is mated, and a first screw hole is provided on the side panel, and a screw passes through the mating groove and is screwed to the first screw hole, thereby removably fixing the material rack to the fixing frame.

[0016] Preferably, the fixing frame includes a fixing frame body, an adjustment plate, a limit plate and an adjustment screw, the adjustment plate is arranged on the side of the fixing frame body away from the side plate, a second screw hole is arranged on the adjustment plate, a waist hole is arranged at the bottom of the matching groove, the screw passes through the second screw hole and the waist hole and is screwed to the first screw hole, the limit plate is fixed to the upper end of the fixing frame body, a third screw hole extending longitudinally is arranged at the upper end of the fixing frame body, the adjustment screw passes through the limit plate and is screwed to the third screw hole.

The tension pulley is arranged above the first synchronous pulley and behind the second synchronous pulley, and is used to change the running direction of the synchronous belt on the side opposite to the third synchronous pulley and control the tension of the synchronous belt.

[0020] After adopting the above technical solution, the utility model has the following beneficial effects.

[0021] 1. A coiling embroidery machine proposed by the utility model is characterized by comprising: a plurality of coiling embroidery heads; a plurality of color-changing material storage devices arranged in one-to-one correspondence with the plurality of coiling embroidery heads. The color-changing material storage device includes a material rack and a turntable attached to the material rack. A plurality of positioning arms are circumferentially and spacedly installed on the turntable. Each positioning arm extends in the axial direction of the turntable, and the extending length only allows one spool assembly to be installed; and a plurality of manipulators arranged in one-to-one correspondence with the plurality of color-changing material storage devices, and used to complete the replacement of the spool assembly between the corresponding color-changing material storage device and the coiling embroidery head; wherein, the material rack of each color-changing material storage device is fixedly arranged relative to the corresponding manipulator. On the one hand, since the positioning arm extends in the axial direction of the turntable and the extending length only allows one spool assembly to be installed, multiple spool assemblies cannot be installed axially on the positioning arm, thus shortening the width of the turntable. On the other hand, since only one spool assembly is allowed to be installed on the positioning arm, the material rack does not need to slide horizontally either, and the coiling embroidery machine does not need to reserve extra space for the horizontal sliding of the material rack, so that the distance between adjacent coiling embroidery heads can be greatly shortened, thereby greatly increasing the installation density of the coiling embroidery heads on the coiling embroidery machine. Under the same floor area, the coiling embroidery products output of the coiling embroidery machine of the utility model is higher. Finally, the material rack is fixedly arranged relative to the corresponding manipulator, so that the relative position between the manipulator and the material rack is fixed, and the manipulator can replace the spool assembly more accurately and stably.

[0022] 2. The rotation of the turntable enables a positioning arm to be in a mating position. The color-changing material storage device has a color-changing state and a material storage state. In the color-changing state, a spool assembly is installed on the positioning arm in the mating position, and the manipulator grabs the spool assembly on the positioning arm in the mating position and installs it on the coiling embroidery head. In the material storage state, no spool assembly is installed on the positioning arm in the mating position, and the manipulator grabs the spool assembly on the coiling embroidery head and installs it on the positioning arm in the mating position. With such a setting, only one manipulator is needed to complete the color change and material storage of the spool assembly, and there is no need to set multiple manipulators to grab or install the spool assembly at multiple positions, thereby reducing the cost of the coiling embroidery machine.

[0023] 3. The color-changing material storage device further includes a first sensor. The first sensor is used to sense whether a tape reel assembly is installed on the positioning arm in the mating position. A sensor mounting seat is provided on the material rack, and the first sensor is installed on the sensor mounting seat. With such a setting, when the color-changing material storage device needs to switch states, the color-changing material storage device can make more accurate judgments and switches, improving the automation efficiency of the color-changing material storage device. At the same time, the sensor mounting seat makes the first sensor more stably installed on the material rack, further improving the stability of the first sensor.

[0024] 4. The color-changing material storage device further includes a check component. The turntable rotates in the first direction to make one positioning arm in the mating position. The check component stops the turntable or the positioning arm to limit the turntable from rotating in the second direction. Since when the manipulator grabs the tape reel assembly on the positioning arm or installs the tape reel assembly onto the positioning arm, the positioning arm will be subjected to the pressing force of the manipulator. Without the check component, it will cause the manipulator to be unable to grab the tape reel assembly or unable to install the tape reel assembly onto the positioning arm. By setting the check component, the probability of failure during the process of the manipulator grabbing and installing the tape reel assembly is reduced or avoided, thereby improving the stability and reliability of the color-changing material storage device during the color-changing and material storage processes.

[0025] 5. The check component includes a check swing rod, a rotating pin, a check spring, and a stop portion. The check swing rod is rotatably installed on the material rack through the rotating pin. The check swing rod includes a check state and an open state. The turntable rotates in the first direction to push the check swing rod away from the stop portion, so that the check swing rod is in the open state, thus avoiding the check swing rod from restricting the rotation of the turntable. The check spring acts on the check swing rod to make the check swing rod have a tendency to return to the check state. In the check state, the check swing rod abuts against the stop portion to limit the turntable from rotating in the second direction. The check of the check component is realized through the check swing rod, the check spring, the rotating pin, and the stop plate. This kind of check component has the advantages of simple structure, firmness, and durability.

[0026] 6. The check component further includes a check slider, a check mounting seat, and a check adjusting block. The check slider is detachably mounted on the check swing rod. When the turntable contacts the check slider, it slides relative to the check slider. The check mounting seat is mounted on the material rack. The rotating pin passes through the check mounting seat and is rotatably mounted on the material rack. The check adjusting block is mounted on the end of the rotating pin away from the check swing rod. The check spring is a torsion spring, and both ends of the check spring are elastically positioned on the check mounting seat and the check adjusting block. A check groove is provided on the material rack, and the check swing rod is placed in the check groove. The groove wall on one side of the check groove forms a stop portion. Since the check component needs to frequently contact and rub against the turntable or the positioning arm, and once the check swing rod is worn out and cannot be used, its replacement is rather troublesome, requiring the disassembly and reassembly of multiple components. By setting the detachable check slider to contact and rub against the turntable or the positioning arm, only one component needs to be replaced when the check slider is worn, thus reducing the operation difficulty of the operator. At the same time, the check mounting seat and the check adjusting block are provided. The check mounting seat improves the rotational stability of the rotating pin and also simplifies the structure of the material rack. The material rack does not need to be designed too thick at the position where the check component is installed. The check adjusting block also simplifies the design of the rotating pin, thus greatly reducing the cost of the check component. Moreover, a check groove is opened on the material rack, which can shorten the distance between the material rack and the turntable, and can further increase the density of the upper head of the disk-tape embroidery machine.

[0027] 7. The turntable includes rotating plates provided at both ends of the positioning arm. The tape reel assembly includes a tape reel bracket and locking sliders mounted on the tape reel bracket. At least part of the locking sliders extend horizontally out of the tape reel bracket, and the locking sliders extending out of the tape reel bracket at least partially overlap with the rotating plates in the horizontal direction. An avoidance position for the manipulator is provided on the rotating plate. With such a setting, the width of the turntable can be further shortened, thereby further increasing the density of the upper head of the disk-tape embroidery machine. At the same time, an avoidance position for the manipulator is provided on the rotating plate, thus avoiding the influence of the reduction of the turntable width on the manipulator's grasping or installing the tape reel assembly.

[0028] 8. The turntable further includes a position sensing disk. Sensing portions corresponding to a plurality of positioning arms one by one are provided on the position sensing disk. A second sensor is provided on the manipulator, and the second sensor senses the sensing portions to control the actions of the manipulator. With such a setting, the manipulator can more accurately judge whether it is in the working position of grasping or installing the tape reel assembly, thereby further improving the accuracy and reliability of the manipulator's grasping or installing the tape reel assembly.

[0029] 9. The color-changing material storage device further includes a fixing frame. The fixing frame is fixedly connected to the machine frame, and the material rack is fixedly connected to the fixing frame. With such a setting, the fixing frame can be designed to be universal, and the material rack can be designed separately according to different models, thereby reducing a part of the cost of the color-changing material storage device.

[0030] 10. The material rack includes a longitudinally extending side panel, and a longitudinally extending matching groove is provided on the fixing frame, at least part of the side panel is matched in the matching groove, and a first screw hole is provided on the side panel, and a screw passes through the matching groove and is screwed to the first screw hole, so that the material rack can be detachably fixed to the fixing frame; in this way, the groove wall of the matching groove can limit the left and right movement of the side panel, so as to avoid the material rack from shaking when the turntable is working and affecting the stability of the turntable when working, and improve the stability and reliability of the color-changing and material-storing device during the color-changing and material-storing process.

[0031] 11. The fixing frame includes a fixing frame body, an adjustment plate, a limit plate and an adjustment screw. The adjustment plate is arranged on the side of the fixing frame body away from the side plate. A second screw hole is arranged on the adjustment plate. A waist hole is arranged at the bottom of the matching groove. The screw passes through the second screw hole and the waist hole and is screwed with the first screw hole. The limit plate is fixed to the upper end of the fixing frame body. A third screw hole extending longitudinally is arranged at the upper end of the fixing frame body. The adjustment screw passes through the limit plate and is screwed with the third screw hole. The fixing frame body is provided with a waist hole, and the side plate and the adjustment plate are fixedly connected by screws, so that the height of the material rack relative to the fixing frame is adjustable. In combination with the limit plate and the adjustment screw, the height adjustment of the material rack relative to the fixing frame is achieved by rotating the adjustment screw. Since the relative positions of the manipulator and the tape embroidery machine head are fixed, and the movement length of the manipulator is also fixed, the color changing and material storage work of the color changing and material storage device needs to be adapted to the manipulator for setting. Through the above structure, the installation position of the material rack can be adjusted, thereby solving the problem of the color changing and material storage device being adapted to the manipulator. At the same time, the installation position of the material rack can be adjusted by rotating the adjusting screw at the upper end of the fixed frame, which also simplifies the operation of the operator and improves the operator's operating experience.

[0032] 12. The material rack includes a driving assembly, which includes a driving motor and a transmission component. The turntable includes a rotating shaft. The driving motor drives the rotating shaft to rotate through the transmission component, thereby driving the turntable to rotate; the transmission component includes a synchronous belt, a first synchronous wheel and a second synchronous wheel. The first synchronous wheel is fixed to the motor shaft of the driving motor, and the second synchronous wheel is fixed to the rotating shaft. The synchronous belt meshes with the first synchronous wheel and the second synchronous wheel to transmit; the transmission component also includes a third synchronous wheel and a tensioning wheel. The third synchronous wheel is arranged above the first synchronous wheel and behind the second synchronous wheel, and is used to change the direction of one side of the synchronous belt. The tensioning wheel is arranged above the first synchronous wheel and behind the second synchronous wheel, and is used to change the direction of the synchronous belt on the opposite side of the third synchronous wheel and control the tension of the synchronous belt. In order to shorten the horizontal distance between the turntable and the tape embroidery machine head, the front end of the material rack needs to provide a clearance space for the tape embroidery machine head to avoid the part. Through the arrangement of the third synchronous wheel and the tensioning wheel, a certain space is provided under the second synchronous wheel. Therefore, the driving component will not interfere with the clearance space of the material rack under the second synchronous wheel. The driving component still has good transmission performance on the basis of avoiding interference with the clearance space of the material rack.

However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0053] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise stated, the meaning of "a plurality" and "several" is two or more, unless otherwise clearly defined.

[0054] In the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0055] As Figure 1-8 shown, the coiling embroidery machine proposed in the embodiment of the present utility model includes a frame 800, a plurality of coiling embroidery heads 700, a plurality of manipulators 600 and a plurality of color-changing material storage devices. The coiling embroidery heads 700, the manipulators 600 and the color-changing material storage devices are in one-to-one correspondence, and the coiling embroidery heads 700 are arranged below the color-changing material storage devices. A plurality of bobbin assemblies 500 are installed on the color-changing material storage devices, and the manipulators 600 are used to complete the replacement of the bobbin assemblies 500 between the color-changing material storage devices and the coiling embroidery heads 700.

[0056] In this embodiment, the color-changing material storage device includes a material rack 100 and a turntable 200 attached to the material rack 100. A plurality of positioning arms 210 are circumferentially spaced and installed on the turntable 200. Each positioning arm 210 extends in the axial direction of the turntable 200 and the extension length only allows one bobbin assembly 500 to be installed. The bobbin assembly 500 can refer to the Chinese patent application with the patent application publication number CN 117089990 A and the patent name "A Coiling Embroidery Bobbin Assembly and a Coiling Embroidery Machine Facilitating Locking".

[0057] Among them, a plurality of coiling embroidery heads 700, a plurality of manipulators 600 and a plurality of color-changing material storage devices are all fixed on the frame 800, and the material rack 100 of each color-changing material storage device is fixedly arranged relative to the corresponding manipulator 600.

[0058] On the one hand, since the positioning arm 210 extends in the axial direction of the turntable 200 and the extension length only allows one bobbin assembly 500 to be installed, multiple bobbin assemblies 500 cannot be installed axially on the positioning arm 210, thus shortening the width of the turntable 200. On the other hand, since only one bobbin assembly 500 is allowed to be installed on the positioning arm 210, the material rack 100 does not need to slide horizontally either, and the coiling embroidery machine does not need to reserve extra space for the horizontal sliding of the material rack 100, so that the distance between adjacent coiling embroidery heads 700 can be greatly shortened, thereby greatly improving the installation density of the coiling embroidery heads 700 on the coiling embroidery machine. With the same floor area, the coiling embroidery products output of the coiling embroidery machine of the present utility model is higher. Finally, the material rack 100 is fixedly arranged relative to the corresponding manipulator 600, so that the relative position between the manipulator 600 and the material rack 100 is fixed, and the manipulator 600 can replace the bobbin assembly more accurately and stably.

[0059] Among them, the material rack 100 is fixedly connected to the frame 800, and the turntable 200 is rotatably installed at one end of the material rack 100 away from the frame 800.

[0060] In this embodiment, the color-changing material storage device further includes a driving assembly 300, the driving assembly 300 includes a driving motor 310 and a transmission component 320, the turntable 200 includes a rotating shaft 230, and the driving motor 310 drives the rotating shaft 230 to rotate through the transmission component 320, thereby driving the turntable 200 to rotate. Among them, the material rack 100 includes a side plate 110, a front plate 120 and a rear plate 130, and a storage cavity for storing at least part of the driving assembly 300 is formed between the side plate 110, the front plate 120 and the rear plate 130.

[0061] In a preferred embodiment, the transmission component 320 includes a synchronous belt 321, a first synchronous wheel 322 and a second synchronous wheel 323, the first synchronous wheel 322 is fixed on the motor shaft of the drive motor 310, and the second synchronous wheel 323 is fixed on the rotating shaft 230, and the synchronous belt 321 engages the first synchronous wheel 322 and the second synchronous wheel 323 to transmit the power.

[0062] In this embodiment, the transmission component 320 further includes a third synchronous wheel 324 and a tension wheel 325. The third synchronous wheel 324 is disposed above the first synchronous wheel 322 and behind the second synchronous wheel 323, and is used to change the direction of one side of the synchronous belt 321. The tension wheel 325 is also disposed above the first synchronous wheel 322 and behind the second synchronous wheel 323, and is used to change the direction of the synchronous belt 321 on the opposite side of the third synchronous wheel 324 and to control the tension of the synchronous belt 321.

[0063] In order to shorten the horizontal distance between the turntable 200 and the tape embroidery machine head 700, the front end of the material rack 100 needs to provide a clearance space for the tape embroidery machine head 700 to avoid the part. By setting the third synchronous wheel 324 and the tensioning wheel 325, a certain space is provided under the second synchronous wheel 323. Therefore, the driving component 300 will not interfere with the clearance space of the material rack 100 under the second synchronous wheel 323. The driving component 300 still has good transmission performance on the basis of avoiding interference with the clearance space of the material rack 100.

[0064] In another preferred embodiment, the transmission component 320 can be a belt and a pulley, or a gear and a chain.

[0065] In this embodiment, the color-changing material storage device further includes a fixed frame 400, which is fixedly connected to the frame 800, and the material rack 100 is detachably fixedly connected to the fixed frame 400. In this way, the fixed frame 400 can be designed to be universal, and the material rack 100 can be designed according to different machine models, thereby reducing the cost of a part of the color-changing material storage device.

[0066] Preferably, in this embodiment, the rack 100 includes a longitudinally extending side plate 110. The fixing frame 400 is provided with a longitudinally extending mating groove 401. At least a part of the side plate 110 is fitted in the mating groove 401. The side plate 110 is provided with a first screw hole, and a screw passes through the mating groove 401 and is screwed with the first screw hole, so that the rack 100 is detachably fixed to the fixing frame 400. Wherein, there are two side plates 110, and two mating grooves 401 are correspondingly provided on the fixed plate frame.

[0067] With such a setting, the groove wall of the mating groove 401 can limit the left - and - right movement of the side plate 110, thereby avoiding the rack 100 from shaking during the operation of the turntable 200, which affects the stability of the turntable 200 during operation, and improving the stability and reliability of the high - color - change material storage device during the color - change and material - storage processes.

[0068] More preferably, in this embodiment, the fixing frame 400 includes a fixing - frame body 410, an adjusting plate 420, a limiting plate 430, and an adjusting screw 440. The adjusting plate 420 is provided at one end of the fixing - frame body 410 facing away from the side plate 110. The adjusting plate 420 is provided with a second screw hole 421. The bottom of the mating groove 401 is provided with a waist - shaped hole 411. A screw passes through the second screw hole 421 and the waist - shaped hole 411 and is screwed with the first screw hole to fixedly connect the adjusting plate 420 and the side plate 110. The fixing - frame body 410 is placed between the adjusting plate 420 and the side plate 110. The limiting plate 430 is fixed to the upper end of the fixing - frame body 410. The adjusting plate 420 is provided with a third screw hole 422 extending longitudinally, and the adjusting screw 440 passes through the limiting plate 430 and is screwed with the third screw hole 422.

[0069] The fixing - frame body 410 is provided with a waist - shaped hole 411, and the side plate 110 and the adjusting plate 420 are fixedly connected by screws, so that the height of the rack 100 relative to the fixing frame 400 is adjustable. Coupled with the limiting plate 430 and the adjusting screw 440, the height adjustment of the rack 100 relative to the fixing frame 400 is realized by rotating the adjusting screw 440. Since the relative positions of the manipulator 600 and the disk - type embroidery head 700 are determined, and the movement length of the manipulator 600 is also determined, the color - change and material - storage operations of the color - change material storage device need to be set to adapt to the manipulator 600. Through the above structure, the installation position of the rack 100 can be adjusted, thus solving the problem of the color - change material storage device adapting to the manipulator 600. At the same time, by rotating the adjusting screw 440 at the upper end of the fixing frame 400, the adjustment of the installation position of the rack 100 can be completed, which also simplifies the operation of the operator and improves the operation experience of the operator.

[0070] In this embodiment, the rotation of the turntable 200 positions a positioning arm 210 in a mating position. The color-changing material storage device has a color-changing state and a material storage state. In the color-changing state, a tape reel assembly 500 is positioned on the positioning arm 210 in the mating position. In the material storage state, no tape reel assembly 500 is installed on the positioning arm 210 in the mating position. The positioning arm 210 in the mating position cooperates with the manipulator 600 of the disk-tape embroidery machine to complete the work of replacing or storing the tape reel assembly.

[0071] With such a setting, only one manipulator 600 is required to complete the color change and material storage of the tape reel assembly 500, eliminating the need to set up multiple manipulators 600 to grasp or install the tape reel assembly 500 at multiple positions, thereby reducing the cost of the disk-tape embroidery machine.

[0072] Preferably in this embodiment, the color-changing material storage device further includes a first sensor 140. The first sensor 140 is used to sense whether a tape reel assembly 500 is installed on the positioning arm 210 in the mating position. A sensor mounting seat 141 is provided on the material rack 100, and the first sensor 140 is installed on the sensor mounting seat 141.

[0073] With such a setting, when the color-changing material storage device needs to switch states, it can make a more accurate judgment and switch, improving the automation efficiency of the color-changing material storage device. At the same time, the sensor mounting seat 141 enables the first sensor 140 to be more stably installed on the material rack 100, further enhancing the stability of the first sensor 140.

[0074] In another preferred embodiment, the color-changing material storage device further includes a check component 150. The turntable 200 rotates in a first direction to position a positioning arm 210 in a mating position, and the check component 150 stops the turntable 200 to limit its rotation in a second direction.

[0075] When the manipulator 600 grabs the tape reel assembly 500 on the positioning arm 210 or installs the tape reel assembly 500 onto the positioning arm 210, the positioning arm 210 will be subjected to the pressing force of the manipulator 600. Without the check component 150, it may cause the manipulator 600 to be unable to grab the tape reel assembly 500 or the tape reel assembly 500 cannot be installed onto the positioning arm 210. By setting up the check component 150, the probability of failure during the process of the manipulator 600 grabbing and installing the tape reel assembly 500 is reduced or avoided, thereby improving the stability and reliability of the color-changing material storage device during color change and material storage.

[0076] In some other embodiments, the check component 150 can also stop the positioning arm 210, thereby restricting the rotation of the turntable 200 in the second direction by stopping the positioning arm 210.

[0077] In a more preferred embodiment of the present example, the check component 150 includes a check swing rod 151, a rotating pin 152, a check spring 153, and a stop portion 154. The check swing rod 151 is rotatably mounted on the material rack 100 through the rotating pin 152. The check swing rod 151 includes a check state and an open state.

[0078] The turntable 200 rotates in the first direction to push the check swing rod 151 away from the stop portion 154, so that the check swing rod 151 is in an open state, thereby preventing the check swing rod 151 from restricting the rotation of the turntable 200. The check spring 153 acts on the check swing rod 151 to make the check swing rod 151 tend to return to the check state. In the check state, the check swing rod 151 abuts against the stop portion 154 to restrict the turntable 200 from rotating in the second direction.

[0079] The check of the check component 150 is realized by the check swing rod 151, the check spring 153, the rotating pin 152, and the check baffle. This kind of check component 150 has the advantages of simple structure, firmness, and durability.

[0080] In some other embodiments, the check component 150 can also adopt a ratchet structure, and the ratchet structure can be arranged on the rotating shaft 230 of the turntable 200.

[0081] In a further preferred embodiment of the present example, the check component 150 further includes a check slider 155, a check mounting seat 156, and a check adjusting block 157. The check slider 155 is detachably mounted on the check swing rod 151. When the turntable 200 contacts the check slider 155, it slides relative to the check slider 155. The check mounting seat 156 is mounted on the material rack 100. The rotating pin 152 passes through the check mounting seat 156 and is rotatably mounted on the material rack 100. The check adjusting block 157 is mounted on the end of the rotating pin 152 away from the check swing rod 151. The check spring 153 is a torsion spring, and both ends of the check spring 153 are elastically positioned on the check mounting seat 156 and the check adjusting block 157. A check groove 158 is provided on the material rack 100, and the check swing rod 151 is placed in the check groove 158. One side wall of the check groove 158 forms the stop portion 154.

[0082] Since the check component 150 needs to often contact and rub against the turntable 200 or the positioning arm 210, and once the check swing rod 151 is worn out and cannot be used, its replacement is rather troublesome and requires the disassembly and reassembly of multiple components. By providing a detachable check slider 155 to contact and rub against the turntable 200 or the positioning arm 210, only one component needs to be replaced when the check slider 155 is worn, thus reducing the operation difficulty for the operator; at the same time, a check mounting seat 156 and a check adjusting block 157 are provided. The check mounting seat 156 improves the rotational stability of the rotating pin 152 and also simplifies the structure of the material rack 100. The material rack 100 does not need to be designed too thick at the position where the check component 150 is installed. The check adjusting block 157 also simplifies the design of the rotating pin 152, thus greatly reducing the cost of the check component 150; furthermore, a check groove 158 is opened on the material rack 100, so that the distance between the material rack 100 and the turntable 200 can be shortened, and the density of the upper head of the coiling embroidery machine can be further improved.

[0083] In another preferred embodiment, the turntable 200 includes rotating plates 220 provided at both ends of the positioning arm 210. The tape reel assembly 500 includes a tape reel bracket and locking sliders 501 mounted on the tape reel bracket. At least part of the locking sliders 501 project laterally out of the tape reel bracket, and the locking sliders 501 that project out of the tape reel bracket at least partially overlap with the rotating plates 220 in the lateral direction; the coiling embroidery machine includes a manipulator 600 for grasping the tape reel assembly 500, and an avoidance position 221 for the manipulator 600 is provided on the rotating plate 220.

[0084] With such a setting, the width of the turntable 200 can be further shortened, so that the density of the upper head of the coiling embroidery machine can be further improved; at the same time, an avoidance position 221 for the manipulator 600 is provided on the rotating plate 220, thus avoiding the influence of the reduction of the width of the turntable 200 on the grasping or installation of the tape reel assembly 500 by the manipulator 600.

[0085] Among them, the avoidance position 221 can be an avoidance inclined surface or an avoidance notch.

[0086] In another preferred embodiment, the color-changing material storage device further includes a position sensing disk 240. Sensing portions 241 corresponding to the plurality of positioning arms 210 one by one are provided on the position sensing disk 240. The coiling embroidery machine includes a manipulator 600 for grasping the tape reel assembly 500, and a second sensor (not shown) is provided on the manipulator 600. The second sensor senses the sensing portions 241 to control the operation of the manipulator 600.

[0087] With such a setting, the manipulator 600 can more accurately judge whether it is in the working position of grasping or installing the tape reel assembly 500, thus further improving the accuracy and reliability of the manipulator 600 in grasping or installing the tape reel assembly 500.

[0088] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that the present utility model includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present utility model will be included in the scope of the claims.
