[0053] Embodiment 1
[0054] This embodiment provides a shuttle replacement device for realizing wireless power supply and communication between an embroidery machine and the shuttle replacement device.
[0055] As Figure 1 shown, it is a schematic structural diagram of the shuttle replacement device provided by this embodiment. The embroidery machine 10 includes: a table board 101, on which the fabric is fixed by an embroidery frame; a machine head 102, a guide rail 103, an electric rail 1031, a shuttle replacement device 104, a conductive contact surface 1041 arranged on the shuttle replacement device, a shuttle 105 arranged under the table board, and a first control module 106 arranged above the table board.
[0056] Among them, the shuttle replacement device 104 is slidably arranged on the guide rail 103, and an electric rail 1031 for supplying power to the shuttle replacement device 104 is arranged on the guide rail, and the electric rail 1031 is connected to a power supply.
[0057] Specifically, the guide rail is fixedly installed under the embroidery machine table board, and a shuttle change device for automatically changing the shuttle of the embroidery machine is slidably installed on the guide rail.

The 24V switching power supply is directly used to supply power to the electric rail. A conductive contact surface is provided on the shuttle change device, and the conductive contact surface contacts the electric rail to provide electric energy for the shuttle change device through the electric rail.
[0060] It should be noted that Figure 1 This is only an exemplary structural schematic diagram, and it does not limit the structure of the embroidery machine in the embodiments of the present application. The installation positions and methods of each component can be set according to actual needs, not limited to Figure 1 this way.
[0061] The shuttle change device provided in this embodiment realizes the minimization or even complete elimination of the cables on the shuttle change device by sliding the shuttle change device on the guide rail, and a power rail for supplying power to the shuttle change device is provided on the guide rail, and the power rail is connected to the power supply. This solves the problem that a large number of cables installed in the existing shuttle change device affect the normal operation of the shuttle change device, and at the same time effectively improves the working efficiency of the shuttle change device.
[0062] Embodiment 2
[0063] This embodiment further supplements and explains the shuttle change device provided in Embodiment 1.
[0064] As Figure 1 shown, as an implementable way, on the basis of the above embodiment, optionally, the shuttle change device further includes: a conductive contact surface 1041 is provided on the shuttle change device 104, and the conductive contact surface 1041 contacts the power rail 1031 to transmit the electric energy on the power rail 1031 to the shuttle change device 104.
[0065] Optionally, the electric rail 1031 includes a first metal strip and a second metal strip, which are respectively fixedly arranged in the groove of the guide rail 103.
[0066] Optionally, the first metal strip and the second metal strip can be metal strips with good conductivity such as copper alloy, or other metals, which are not limited in this embodiment.
[0067] Specifically, the electric rail includes a first metal strip and a second metal strip, which are respectively fixedly arranged in the groove of the guide rail. The length of the electric rail is the same as that of the guide rail. The electric rail is connected to the power supply. The common working voltage of the shuttle change device is 24V. The 24V switching power supply is directly used to supply power to the metal strip. There is a conductive contact surface on the shuttle change device. The shuttle change device is slidably installed on the guide rail. The conductive contact surface on the shuttle change device contacts the electric rail. In this way, the power supply, the metal strip and the shuttle change device form a complete power supply loop, so as to realize power supply for the shuttle change device through the electric rail without setting any power supply cables.
[0068] As Figure 2 shown, it is a schematic structural diagram of the shuttle change device provided by this embodiment. As another implementable way, on the basis of the above embodiment, optionally, the shuttle change device further includes:
[0069] A second control module 1042, configured to control the shuttle change device 104 to replace the shuttle 105 according to the control signal sent by the embroidery machine 10.
[0070] Optionally, the second control module 1042 is also wirelessly connected to the wireless communication module 107 of the embroidery machine 10. The wireless communication module 107 is connected to the signal conversion module 108 of the embroidery machine 10. The signal conversion module 108 is connected to the first control module 106 of the embroidery machine 10 through the CAN bus.
[0071] Optionally, the second control module 1042 controls the shuttle change device 104 to replace the shuttle 105 according to the control signal sent by the first control module 106.
[0072] Optionally, the wireless communication module can adopt a ZigBee wireless communication module, and the signal conversion module can adopt a CAN-to-ZigBee signal converter, which realizes the signal conversion between CAN signals and ZigBee signals.
[0073] Specifically, the wireless communication module of the bobbin winder replacement device uses the ZigBee protocol for wireless communication, while the control instructions of the first control module of the embroidery machine are generally based on the CAN protocol. To enable wireless communication between the bobbin winder replacement device and the embroidery machine, the CAN-to-ZigBee signal converter is connected to the first control module of the embroidery machine through the CAN bus. The CAN-to-ZigBee signal converter converts the ZigBee signal into a CAN signal, and the CAN signal is transmitted to the first control module of the embroidery machine through the CAN bus.
[0074] The bobbin winder replacement device includes a second control module. The second control module and the wireless communication module of the embroidery machine transmit control signals through wireless communication. The wireless communication module enables the bobbin winder replacement device and the first control module of the embroidery machine to transmit control signals without any data cables. The second control module controls the bobbin winder replacement device to replace the bobbin on the embroidery machine according to the control signal sent by the first control module.
[0075] As Figure 3 shown, it is a schematic structural diagram of a wireless communication module and a signal conversion module provided in this embodiment. As an implementable manner, on the basis of the above embodiment, optionally, the wireless communication module 107 and the signal conversion module 108 are integrated on the same circuit board, which can be called the embroidery machine circuit board.
[0076] Specifically, the ZigBee wireless communication module and the CAN-to-ZigBee signal converter are both arranged on the same circuit board of the embroidery machine. The circuit board transmits signals to the first control module of the embroidery machine through the CAN bus.
[0077] As Figure 4 shown, it is another schematic structural diagram of a wireless communication module and a signal conversion module provided in this embodiment. As an implementable manner, on the basis of the above embodiment, optionally, the wireless communication module 107 includes a ZigBee module 1071.
[0078] Optionally, the ZigBee wireless communication technology can be applied to small-scale wireless communication-based control and automation fields, etc. It can eliminate the need for wired cables between computer devices or a series of digital devices, and can more effectively realize wireless networking between various different digital devices, enabling them to communicate with each other.
[0079] Specifically, the wireless communication module can adopt a ZigBee wireless communication module to realize wireless communication between the bobbin winder replacement device and the embroidery machine.
[0080] Optionally, a material tray and a gripper may be provided on the bobbin shuttle replacement device. The material tray may be disc-shaped or may be set into other shapes according to actual requirements. A circle of bobbin shuttle positions may be evenly provided at the edge of the material tray, and the bobbin shuttle filled with the bobbin thread is placed on the bobbin shuttle position.
[0081] Optionally, before the bobbin shuttle replacement device operates, an operator may place the bobbin shuttle filled with the bobbin thread on the bobbin shuttle position of the material tray. When the bobbin shuttle replacement device replaces the bobbin shuttle of the embroidery machine, the bobbin shuttle replacement device first takes the bobbin shuttle to be replaced from the embroidery machine through the gripper, places the bobbin shuttle into the vacant bobbin shuttle position on the material tray, then takes the bobbin shuttle filled with the bobbin thread from the material tray, and installs the bobbin shuttle filled with the bobbin thread onto the embroidery machine.
[0082] As an exemplary implementation manner, as Figure 5 shown, it is a schematic structural diagram of the exemplary bobbin shuttle replacement device provided in this embodiment.
[0083] Optionally, the bobbin shuttle replacement device 104 further includes: a first motor 1043, a second motor 1044, a third motor 1045, a fourth motor 1046, and a fifth motor 1047. The first motor 1043, the second motor 1043, the third motor 1045, the fourth motor 1046, and the fifth motor 1047 are respectively connected to the second control module 1042.
[0084] The first motor 1043 is used to control the sliding of the bobbin shuttle replacement device 104 on the guide rail 103.
[0085] The second motor is used to adjust the distance between the bobbin shuttle replacement device 104 and the bobbin shuttle 105 on the embroidery machine 10. The fourth motor 1046 is used to adjust the distance between the gripper and the material tray. The fifth motor 1047 is used to control the gripper to grab the bobbin shuttle 105 from the material tray or place the bobbin shuttle 105 replaced from the embroidery machine 10 onto the vacant bobbin shuttle position. The third motor 1045 is connected to the material tray and is used to control the rotation of the material tray.
[0086] Optionally, the bobbin shuttle replacement device may include a first motor. Since the guide rail is regarded as the X axis, the first motor may also be called the X-axis motor. The bobbin shuttle replacement device is slidably installed on the guide rail under the embroidery machine table board. The bobbin shuttle replacement device slides on the guide rail under the drive of the first motor to replace the bobbin shuttle of the head of the embroidery machine that needs to replace the bobbin shuttle. The bobbin shuttle replacement device can slide to the position corresponding to the guide rail of the bobbin shuttle to be replaced, so as to realize the replacement operation of the bobbin shuttle.
[0087] Optionally, the shuttle changing device may further include a second motor. Since the lifting direction of the shuttle changing device is regarded as the Z-axis, the second motor can also be called the Z-axis motor. The second motor is mainly used to adjust the height difference between the shuttle changing device and the shuttle on the embroidery machine. If the height distance between the shuttle changing device slidably mounted on the guide rail and the shuttle is too large or too small, the shuttle changing device cannot complete the replacement of the shuttle. When the height of the shuttle changing device is suitable for the shuttle changing device to replace the shuttle, there will be a baffle blocking the normal sliding of the shuttle changing device on the guide rail. By adjusting the distance between the shuttle changing device and the shuttle on the embroidery machine, the replacement operation of the shuttle on the embroidery machine is realized.
[0088] Optionally, the shuttle changing device may further include a third motor. The third motor can also be called the turntable motor. The third motor is used to control the rotation of the turntable. During the process of the shuttle changing device replacing the shuttle for the embroidery machine, the shuttle changing device continuously repeats the operations of placing and taking the shuttle on the turntable. The turntable rotates a preset angle according to the shuttle position requirements of the shuttle changing device, so as to ensure the normal progress of the shuttle replacement operation of the shuttle changing device.
[0089] Optionally, the shuttle changing device may further include a fourth motor. The fourth motor can also be called the swing motor. The fourth motor is mainly used to adjust the distance between the gripper and the turntable. During the process of the shuttle changing device replacing the shuttle for the embroidery machine, the gripper continuously repeats the operations of placing and taking the shuttle on the turntable. Placing and taking are two different-direction movements of the gripper. This swinging process is realized by the drive of the fourth motor.
[0090] Optionally, the shuttle changing device may further include a fifth motor. The fifth motor can also be called the gripper motor. The fifth motor can control the grasping and releasing of the gripper. The fifth motor is mainly used to control the gripper to grasp the shuttle from the turntable, or place the shuttle replaced from the embroidery machine onto the empty shuttle position.
[0091] Optionally, due to the high control precision requirement of the first motor, the first motor can adopt closed-loop control. The precision requirements of the second, third, fourth, and fifth motors are not as high as those of the first motor, so the second, third, fourth, and fifth motors can adopt open-loop control. The first, second, third, and fourth motors can be stepper motors, and the fifth motor can be a linear motor. The first, second, third, and fourth motors are equipped with sensors, which mainly include photoelectric sensors or magnetic encoders, etc. In open-loop control, the magnetic encoder in the sensor determines the rotation angle of the output shaft of the stepper motor based on the induction signal of the sensor origin position and the number of electrical pulse signals of the driving motor, and then determines the position of the component driven by the motor. During the operation of the shuttle change device, the control parameters of the motor are adjusted according to the number of electrical pulse signals, thereby realizing the position adjustment of the component driven by the motor.
[0092] Optionally, when the gripper fails to remove the shuttle from the embroidery machine or fails to install a new shuttle onto the embroidery machine, this operation can be repeated a preset number of times. The preset number can be set according to actual requirements, such as set to 2 times, 3 times, 5 times, etc. If the shuttle replacement still cannot be achieved after repeated execution, or if other operation failure problems occur in the shuttle change device, the shuttle change device can perform error handling.
[0093] Optionally, error handling can include: the shuttle change device with an error restores the fourth motor to the origin position, that is, the gripper returns to the initial position. If there is no shuttle in the gripper at this time, the gripper opens, and the second control module of the shuttle change device can send an error report to the first control module of the embroidery machine. The second control module of this shuttle change device can send an error report to other shuttle change devices on the same embroidery machine. After receiving the error report, when all the shuttles of the heads they are responsible for have been replaced, these other shuttle change devices stay in the current position, and when they receive a clear control instruction to return to the preset initial position, the shuttle change devices return to the preset initial position.
[0094] Optionally, the shuttle change device and the embroidery machine can have an interlock function, which can be realized through the wireless communication protocol between the first control module of the embroidery machine and the second control module of the shuttle change device. The interlock function means that when the shuttle change device is performing shuttle replacement work, the embroidery machine is in a stopped state, and when the embroidery machine is performing embroidery work, the shuttle change device shields any start instructions for it.
[0095] As an implementable manner, on the basis of the above embodiments, optionally, the control signal sent by the embroidery machine 10 includes the identification information of the bobbin winder replacement device 104; the second control module 1042 is further configured to determine whether the identification information is consistent with the identification information of the bobbin winder replacement device 104. If they are consistent, the control signal is responded to; if they are inconsistent, the control signal is not responded to.
[0096] Optionally, the second control module 1042 is further configured to communicate with other bobbin winder replacement devices 104 through the wireless communication module 107.
[0097] Specifically, when the first control module of the embroidery machine only wants to perform wireless communication with one of the multiple bobbin winder replacement devices, the signal sent by the first control module of the embroidery machine may carry the identification information of the bobbin winder replacement device. This identification information may be the address code of the preset bobbin winder replacement device, and the address codes of each bobbin winder replacement device are different. This signal is converted into a ZigBee signal through a CAN-to-ZigBee signal converter, and then the ZigBee signal is sent to the wireless communication module of the bobbin winder replacement device. When the wireless communication module of other bobbin winder replacement devices receives the ZigBee signal, the second control module of the bobbin winder replacement device identifies the address code in the ZigBee signal. When the address code is consistent with its own address code, the ZigBee signal is responded to; if it is found that the identification information in the ZigBee signal does not match its own identification information, the ZigBee signal is not responded to.
[0098] Optionally, the address code can start from 0 or 1 and increment. Multiple bobbin winder replacement devices on the embroidery machine can achieve communication and information transmission between the bobbin winder replacement devices through the ZigBee signal with the identification information of the bobbin winder replacement device.
[0099] As an implementable manner, on the basis of the above embodiments, optionally, the embroidery machine 10 includes one or more of the above-mentioned bobbin winder replacement devices 104.
[0100] Optionally, one head can be set on an embroidery machine, or dozens or even hundreds of heads can be set. Each tray of the bobbin winder replacement device can hold eight bobbins each time.
[0101] Specifically, the number of bobbins corresponding to the embroidery machine heads that the bobbin winder replacement device can serve each time is limited. To ensure that all the heads on the embroidery machine can work properly, multiple bobbin winder replacement devices can be set on the embroidery machine.
[0102] It should be noted that the gripper, the material tray, the first motor, the second motor, the third motor, the fourth motor and the fifth motor can be installed according to actual needs. In this embodiment, each implementable mode can be implemented independently, or can be implemented in any combined manner without conflict. The present application does not make any limitations.
[0103] The shuttle replacement device provided in this embodiment realizes minimizing or even completely eliminating the cables on the shuttle replacement device by sliding the shuttle replacement device on the guide rail, on which there is an electric rail for powering the shuttle replacement device, and the electric rail is connected to the power supply. This solves the problem that a large number of cables installed in the existing shuttle replacement device affect the normal operation of the shuttle replacement device, and at the same time effectively improves the working efficiency of the shuttle replacement device.
[0104] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
