Description

Technical Field

[0001] The invention relates to the technical field of chemical fiber production and manufacturing, and in particular to an automatic transport vehicle for chemical fiber cakes. Background Art

[0002] The winding machine is a device that winds the chemical fiber into a silk cake and outputs the silk cake in a string in the chemical fiber production process. In order to facilitate the transportation of the silk cake string output by the winding machine to the silk cake hanging place, a chemical fiber silk cake automatic transport vehicle is usually placed in the workshop, which mainly includes an automatic guided vehicle and a workbench set on one side of the automatic guided vehicle. A silk cake tube is horizontally arranged on the workbench, and a pushing mechanism is arranged on the silk cake tube. When carrying out the handling operation, the automatic guided vehicle can move the workbench to the discharge port of the winding machine to complete the docking of the silk cake tube on the workbench with the silk cake tube at the discharge port of the winding machine. When the winding machine outputs the silk cake, multiple silk cakes can enter the silk cake tube on the workbench in a string along the silk cake tube on the winding machine, thereby completing the reception of the silk cake string. After receiving the silk cake string, the workbench is pushed to the silk cake hanging place by the automatic guided vehicle, and then the silk cake string is pushed from the silk cake tube on the workbench to the hanging rod of the hanging rack by the pushing mechanism, thereby completing the transportation of the silk cake string. For example, the invention application with the publication number CN107826869A discloses a similar chemical fiber cake transporter.

[0003] In the above-mentioned automatic handling vehicle for chemical fiber yarn cakes, the yarn cake tube on the workbench is in the shape of a horizontal round rod. When receiving or outputting the yarn cake, the center hole of the yarn cake will produce friction with the upper surface of the yarn cake tube. Since the yarn cake itself is heavy, it will cause greater wear on the upper surface of the yarn cake tube over time, causing the side wall of the yarn cake tube to become thinner. In order to avoid the risk of deformation or even breakage of the yarn cake tube due to thinning of the side wall, the yarn cake tube is generally replaced regularly. However, replacing the entire yarn cake tube not only has high material costs, but also troublesome operation, so there is room for improvement. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides an automatic transport vehicle for chemical fiber yarn cakes, which can reduce the replacement cost of yarn cake tubes and simplify the replacement process, thereby achieving the purpose of reducing costs and increasing efficiency.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0006] A chemical fiber yarn cake automatic transport vehicle comprises an automatic guided vehicle, a workbench arranged on one side of the automatic guided vehicle, a mounting seat arranged above the workbench, and a yarn cake tube horizontally arranged on one side of the mounting seat, the upper surface of the yarn cake tube is provided with a mounting groove connected to the inner cavity of the yarn cake tube along its length direction, a replaceable cover plate is covered above the mounting groove, and the replaceable cover plate is bent into an arc shape to fit the upper surface of the yarn cake tube; a plurality of buckles are arranged below the two side edges of the replaceable cover plate along its length direction, and positioning strips are provided on both sides of the yarn cake tube along its length direction, respectively abutting against the lower side edges of the replaceable cover plate, and the positioning strips are provided with slots for one-to-one corresponding insertion of a plurality of buckles on the corresponding sides along its length direction, and the buckles A card slot is provided on the front side of the cover, and when the buckle inserted in the slot moves forward with the replaceable cover plate, the card slot can be engaged with the front edge of the corresponding slot to prevent the buckle from escaping from the slot, and at the same time, a movable gap can be generated between the rear end of the replaceable cover plate and the side surface of the mounting seat, and at least one locking block for preventing the replaceable cover plate from retreating is embedded in the movable gap, and a power source for driving the locking block to enter or leave the movable gap is provided on the mounting seat; a pushing mechanism is provided on the bobbin tube to move along the length direction of the bobbin tube to push the bobbin away from the bobbin tube, a guiding mechanism that moves with the pushing mechanism to keep the pushing mechanism in a linear motion trajectory, and a horizontal pushing mechanism that is linked to the guiding mechanism to lift the sunken part of the replaceable cover plate.

[0007] By adopting the above scheme, the detachable connection between the replaceable cover plate and the bobbin tube can realize the rapid replacement of the upper surface of the bobbin tube, thereby saving the replacement cost of the entire bobbin tube and improving the replacement efficiency and convenience. The pushing mechanism can push the bobbin hanging on the bobbin tube away, thereby realizing the output of the bobbin. The guide mechanism can improve the operation accuracy and stability of the pushing mechanism. During the operation of the guide mechanism, it can synchronously drive the push mechanism to operate, so as to lift the part of the replaceable cover plate that sinks due to pressure, thereby reducing the damage rate of the replaceable cover plate, thereby extending the service life of the replaceable cover plate, and further reducing the use cost and replacement cost.

[0008] Preferably, the pushing mechanism comprises a pushing block arranged at the lower side of the bobbin tube to abut against the inner end surface of the bobbin and a driving assembly arranged in the bobbin tube to drive the pushing block to move along the length direction of the bobbin tube.

[0009] By adopting the above scheme, the push block can form a force-bearing surface on the inner end surface of the silk cake, so that it can stably drive the silk cake to leave the silk cake tube under the drive of the driving component, thereby ensuring the discharge accuracy and stability of the silk cake tube.

[0010] Preferably, the driving assembly includes a lead screw rotatably arranged in the wire cake tube along the length direction of the wire cake tube, a nut threadedly engaged with the lead screw, a connecting piece connected between the nut and the push block, and a driving device arranged on the mounting seat to drive the lead screw to rotate, and the lower side wall of the wire cake tube is provided with an avoidance groove along its length direction for the movement of the connecting piece.

[0011] By adopting the above scheme, the rotational cooperation between the lead screw and the nut can be converted into reciprocating linear motion of the nut along the length direction of the lead screw, thereby improving the operating accuracy and stability of the push block, and further ensuring the pushing efficiency and accuracy of the wire cake.

[0012] Preferably, the guide mechanism includes a guide sleeve coaxially arranged on the outside of the nut and a plurality of guide wheel groups arranged on the outer peripheral surface of the guide sleeve, each guide wheel group includes at least one guide wheel installed on the outer side wall of the guide sleeve, the rotation plane of the guide wheel is arranged along the length direction of the bobbin tube and the outer peripheral surface of the guide wheel abuts against the inner side wall of the bobbin tube.

[0013] By adopting the above scheme, the abutment between the guide wheel and the inner wall of the bobbin tube can not only eliminate the movable gap between the guide sleeve and the inner wall of the bobbin tube, thereby ensuring the stability of the push block during operation, but also effectively reduce the friction between the guide sleeve and the inner wall of the bobbin tube, thereby improving the smoothness of the push block during operation.

[0014] Preferably, a guide block is extended from the lower side of the guide sleeve and inserted into the avoidance groove.

[0015] By adopting the above solution, the sliding cooperation between the guide block and the avoidance groove can limit the circumferential rotation of the guide sleeve, further improving the stability of the push block during operation.

[0016] Preferably, rollers abutting against the side walls of the avoidance groove are arranged on both sides of the guide block, and the rotation plane of the rollers is arranged along the length direction of the bobbin tube.

[0017] By adopting the above solution, the roller can reduce the friction between the guide block and the avoidance groove, thereby improving the stability and smoothness of the guide block during operation.

[0018] Preferably, the push mechanism is a guide wheel group located at the top of the guide sleeve, and the guide wheel group includes at least one pressure wheel installed on the outer wall of the guide sleeve, and the outer peripheral surface of the pressure wheel abuts against the inner wall of the replaceable cover plate.

[0019] By adopting the above scheme, when the guide sleeve runs with the nut, it can sweep the replaceable cover plate along the length direction of the wire cake tube, so as to flatten the part of the replaceable cover plate that sinks due to pressure through the pressure wheel, thereby increasing the usable time of the replaceable cover plate and further reducing its replacement cost.

[0020] Preferably, the outer peripheral surface of the pressure wheel is in the shape of an arc protruding outward to adapt to the inner arc surface of the replaceable cover plate.

[0021] By adopting the above solution, the outer peripheral surface of the pressure wheel can fit the inner side wall of the replaceable cover plate more closely and the contact area between the two is larger, thereby improving the lifting and restoring effect of the pressure wheel on the replaceable cover plate.

[0022] Preferably, the pressure wheel is arranged on a mounting block, and a plug-in groove for longitudinal sliding and plugging of the mounting block is provided on the upper surface of the guide sleeve, and sliding rods are provided on both sides of the mounting block, and two opposite side walls in the plug-in groove are provided with sliding grooves for longitudinal sliding and plugging of the two sliding rods respectively, and an anti-dropping piece for preventing the sliding rod from escaping from the sliding groove is provided at the upper end of the sliding groove; a pressure detection unit for detecting the pressure value between the mounting block and the plug-in groove to output a pressure detection signal is provided between the bottom of the mounting block and the plug-in groove, and a control unit for receiving the pressure detection signal is coupled to the pressure detection unit, and a wireless transmitting unit controlled by the control unit is coupled to the control unit, and the wireless transmitting unit The wireless connection is provided with a wireless receiving unit, a controller is coupled to the wireless receiving unit, and a power source is coupled to and controlled by the controller; the control unit can wirelessly transmit the pressure detection signal sent by the pressure detection unit to the wireless receiving unit through the wireless transmitting unit, and the wireless receiving unit can send the received pressure detection signal to the controller, and a pressure threshold and a number threshold are preset in the controller; when the pressure wheel lifts the sunken part of the replaceable cover plate so that the pressure value between the mounting block and the plug-in slot is greater than the pressure threshold, the controller can count once, and when the metering times reaches the number threshold, the controller controls the power source to operate to drive the locking block to leave the active interval.

[0023] With the above solution, each time the pressure wheel lifts the sunken part of the replaceable cover, the controller can automatically count once. When the number of measurements reaches the threshold, it means that the fatigue life of the replaceable cover has reached its limit. In order to avoid large-scale deformation or breakage of the replaceable cover, which may cause damage to the bobbin tube and the structure inside the bobbin tube, the controller can control the power source to drive the locking block to withdraw from the movable interval so that the replaceable cover can retreat, so that the card slot on the buckle can be separated from the edge of the slot, and then the replaceable cover can be unlocked, so that the replaceable cover can be replaced, thereby maintaining the performance of the bobbin tube. The wireless connection between the wireless transmitting unit and the wireless receiving unit can free the signal transmission between the control unit and the controller from the constraints of the wiring harness, thereby preventing the wiring harness from being entangled and broken when the pressure detection unit and the control unit move with the guide sleeve, making the operation of the mechanism more stable and reliable.

[0024] Preferably, the controller is also coupled with a locking button, an unlocking button and a prompting unit; when the locking button sends a locking signal to the controller in response to an external trigger, the controller can control the power source to drive the locking block into the active interval to prevent the replaceable cover from moving backward; when the unlocking button sends an unlocking signal to the controller in response to an external trigger, the controller can control the power source to drive the locking block out of the active interval to allow the replaceable cover to move backward; when the controller's metering times reaches a threshold number, the controller can control the prompting unit to give a prompt.

[0025] With the above solution, when the number of times the pressure wheel lifts the sunken part of the replaceable cover plate reaches the number threshold, the controller can control the prompt unit to give a prompt to remind the staff to replace the replaceable cover plate in time, thereby improving work efficiency. By triggering the lock button and the unlock button, the replaceable cover plate can be actively locked and unlocked, which is convenient for the staff to maintain the mechanism in the bobbin tube, further improving the operating efficiency and convenience.

[0026] The present invention has significant technical effects due to the adoption of the above technical solutions: the detachable connection between the replaceable cover plate and the bobbin tube can realize the rapid replacement of the upper surface of the bobbin tube, thereby saving the replacement cost of the entire bobbin tube and improving the replacement efficiency and convenience. The pushing mechanism can push away the bobbin hanging on the bobbin tube, thereby realizing the output of the bobbin. The guide mechanism can improve the operating accuracy and stability of the pushing mechanism. During the operation of the guide mechanism, it can synchronously drive the push mechanism to operate, so as to lift the part of the replaceable cover plate that sinks due to pressure, thereby reducing the damage rate of the replaceable cover plate, thereby extending the service life of the replaceable cover plate, and further reducing the use cost and replacement cost.

The workbench 2 is located at the bottom of the automatic guided vehicle 1, and a plurality of support wheels 39 are arranged at the bottom of the workbench 2 to improve the stability and smoothness of the workbench 2 and the automatic guided vehicle 1 during operation. The upper surface of the yarn cake tube 4 is provided with a mounting groove 5 connected to the inner cavity of the yarn cake tube 4 along its length direction, and a replaceable cover plate 6 is covered above the mounting groove 5, and the replaceable cover plate 6 is bent into an arc shape to fit the upper surface of the yarn cake tube 4. A plurality of buckles 7 are arranged along the length direction below the two side edges of the replaceable cover plate 6, and a positioning strip 8 is provided on both sides of the silk cake tube 4 along its length direction, which respectively abuts against the two side edges below the replaceable cover plate 6. The positioning strip 8 is provided with slots 9 for the corresponding side buckles 7 to be plugged in one by one along its length direction, and a card slot 10 is provided on the front side of the buckle 7. When the buckle 7 inserted in the slot 9 moves forward with the replaceable cover plate 6, the card slot 10 can be engaged with the front side edge of the corresponding slot 9 to prevent the buckle 7 from detaching from the slot 9, and at the same time, a movable gap 11 can be generated between the rear end of the replaceable cover plate 6 and the side of the mounting seat 3. At least one locking block 12 for preventing the replaceable cover plate 6 from retreating is embedded in the movable gap 11. The shape of the locking block 12 is adapted to the shape of the side wall of the replaceable cover plate 6, so that the outer surface of the replaceable cover plate 6 is smoother after the locking block 12 enters the movable gap 11. A power source 13 for driving the locking block 12 to enter or leave the movable interval 11 is disposed on the mounting seat 3 . The power source 13 is preferably a cylinder, and an output shaft of the cylinder is fixed to the outer side wall of the locking block 12 .

[0048] In order to realize the output of the wire cake 40, the wire cake tube 4 is provided with a pushing mechanism that moves along the length direction of the wire cake tube 4 to push the wire cake 40 away from the wire cake tube 4, a guide mechanism that moves with the pushing mechanism to keep the pushing mechanism in a straight motion trajectory, and a horizontal pushing mechanism that is linked to the guide mechanism to lift the sunken part of the replaceable cover plate 6. Among them, the pushing mechanism includes a pushing block 14 arranged on the lower side of the wire cake tube 4 to abut against the inner end surface of the wire cake 40 and a driving component arranged in the wire cake tube 4 to drive the pushing block 14 to move along the length direction of the wire cake tube 4. The cross section of the pushing block 14 is in the shape of an arc, so that the thrust formed on the inner end surface of the wire cake 40 is more uniform, thereby improving the accuracy and balance when pushing the wire cake 40. The driving assembly includes a lead screw 15 that is rotatably arranged in the screw tube 4 along the length direction of the screw tube 4, a nut 16 that is threadedly matched with the lead screw 15, a connecting piece 17 that is connected between the nut 16 and the push block 14, and a driving device that is arranged on the mounting seat 3 to drive the lead screw 15 to rotate. The lower side wall of the screw tube 4 is provided with an escape groove 19 for the connecting piece 17 to move along its length direction. Among them, a bearing with a seat (not shown) is arranged between the two ends of the lead screw 15 and the inner side walls of the two ends of the screw tube 4, thereby effectively improving the support and smoothness of the lead screw 15 during operation. A collar 42 is fixedly sleeved on the nut 16, and the connecting piece 17 is integrally connected between the collar 42 and the push block 14. One end of the lead screw 15 away from the screw tube 4 exceeds the mounting seat 3, and the driving device is a motor 18 fixed on the mounting seat 3. The output shaft of the motor 18 is connected to the part of the lead screw 15 that exceeds the mounting seat 3 through a belt transmission assembly 41 to achieve stable rotation of the lead screw 15.

[0049] In order to achieve precise guidance and smooth transmission of the guide mechanism, the guide mechanism includes a guide sleeve 20 coaxially sleeved on the outside of the screw nut 16 and a plurality of guide wheel groups 21 ring-arranged on the outer peripheral surface of the guide sleeve 20, each guide wheel group 21 includes two guide wheels 22 mounted on the outer side wall of the guide sleeve 20, the rotation plane of the guide wheel 22 is arranged along the length direction of the wire cake tube 4 and the outer peripheral surface of the guide wheel 22 abuts against the inner side wall of the wire cake tube 4. Among them, the guide sleeve 20 and the collar 42 are axially fixed to the flange 44 at one end of the screw nut 16 by the bolt assembly 43, thereby realizing the fixed connection between the guide sleeve 20, the push block 14 and the screw nut 16, so that the screw nut 16 can drive the guide sleeve 20 and the push block 14 to operate stably.

[0050] In order to limit the circumferential rotation of the guide sleeve 20 and the nut 16, a guide block 23 is extended from the lower side of the guide sleeve 20 and inserted into the avoidance groove 19. Rollers 24 are arranged on both sides of the guide block 23 to abut against the side walls of the avoidance groove 19, and the rotation plane of the roller 24 is arranged along the length direction of the bobbin tube 4 to ensure the smoothness and stability of the guide block 23 during operation.

[0051] In order to realize the lifting function of the horizontal push mechanism to extend the service life of the replaceable cover plate 6, the horizontal push mechanism is a guide wheel group 21 located at the top of the guide sleeve 20, and the guide wheel group 21 includes two pressure wheels 25 installed on the outer wall of the guide sleeve 20, and the outer peripheral surface of the pressure wheel 25 abuts against the inner wall of the replaceable cover plate 6. The outer peripheral surface of the pressure wheel 25 is in an arc shape protruding outward to adapt to the inner arc surface of the replaceable cover plate 6, thereby improving the lifting effect of the pressure wheel 25.

[0052] In order to determine the fatigue life of the replaceable cover plate 6 and facilitate the staff to replace the replaceable cover plate 6 when the life is exhausted, the pressure wheel 25 is set on a mounting block 26, and the upper surface of the guide sleeve 20 is provided with a plug-in slot 27 for the mounting block 26 to slide and plug in longitudinally. Slide rods 28 are fixedly provided on both sides of the mounting block 26, and two opposite side walls in the plug-in slot 27 are provided with slide grooves 29 for the two slide rods 28 to slide and plug in longitudinally, so that the mounting block 26 can perform stable longitudinal displacement in the plug-in slot 27. The upper end of the slide groove 29 is fixedly provided with an anti-dropping member 30 to prevent the slide rod 28 from escaping from the slide groove 29, thereby effectively preventing the mounting block 26 from escaping from the plug-in slot 27, making the structure more stable. A pressure detection unit 31 for detecting the pressure value between the mounting block 26 and the plug-in slot 27 to output a pressure detection signal is provided between the bottom of the mounting block 26 and the plug-in slot 27. The pressure detection unit 31 is a pressure strain gauge attached to the bottom of the plug-in slot 27. A control unit 32 for receiving the pressure detection signal is coupled to the pressure detection unit 31. The control unit 32 is preferably a single-chip microcomputer. A wireless transmitting unit 33 controlled by the control unit 32 is coupled to the control unit 32. The wireless transmitting unit 33 is wirelessly connected to a wireless receiving unit 34. The wireless transmitting unit 33 and the wireless receiving unit 34 are paired Bluetooth modules, thereby achieving a stable connection of wireless signals. Among them, the control unit 32 and the wireless transmitting unit 33 are both integrated on a circuit board 45, and the four corners of the circuit board 45 are fixed to the side of the mounting block 26 by screws 46. A power supply module 47 is also provided on the circuit board 45. The power supply module 47 is a rechargeable battery or a button battery, which can power the components on the circuit board 45. In order to protect the circuit board 45, a protective shell 48 for wrapping the circuit board 45 is fixed on the mounting block 26. A controller 35 is coupled to the wireless receiving unit 34, and the controller 35 is preferably a PLC. The power source 13 is coupled to and controlled by the controller 35 through the solenoid valve 49, thereby realizing precise control of the power source 13. In this embodiment, the control unit 32 can wirelessly send the pressure detection signal sent by the pressure detection unit 31 to the wireless receiving unit 34 through the wireless transmitting unit 33, and the wireless receiving unit 34 can send the received pressure detection signal to the controller 35. A pressure threshold and a number threshold are preset in the controller 35. When the pressure wheel 25 lifts the sunken part of the replaceable cover plate 6 so that the pressure value between the mounting block 26 and the plug-in slot 27 is greater than the pressure threshold, the controller 35 can count once. When the metering times reaches the number threshold, it means that the fatigue life of the replaceable cover plate 6 has reached the limit, and the controller 35 can control the power source 13 to operate to drive the locking block 12 to leave the active interval 11, thereby realizing the unlocking of the replaceable cover plate 6.

[0053] In order to realize active locking and unlocking of the replaceable cover plate 6, the controller 35 is also coupled with an external locking button 36, an unlocking button 37 and a prompting unit 38. In this embodiment, when the locking button 36 sends a locking signal to the controller 35 in response to an external trigger, the controller 35 can control the power source 13 to drive the locking block 12 into the active interval 11 to prevent the replaceable cover plate 6 from retreating; when the unlocking button 37 sends an unlocking signal to the controller 35 in response to an external trigger, the controller 35 can control the power source 13 to drive the locking block 12 to withdraw from the active interval 11 so that the replaceable cover plate 6 can retreat. The prompting unit 38 is preferably a buzzer. When the metering times of the controller 35 reach the times threshold, the controller 35 can control the prompting unit 38 to issue a sound prompt to remind the staff to replace the replaceable cover plate 6 in time.

[0054] The specific usage process is as follows:

[0055] When installing the replaceable cover plate 6, first trigger the unlock button 37 so that the controller 35 can control the power source 13 to operate through the solenoid valve 49, so that the power source 13 drives the locking block 12 to withdraw from the position of the active interval 11. At this time, the replaceable cover plate 6 is covered on the installation slot 5 so that the buckle 7 on the replaceable cover plate 6 enters the corresponding slot 9, and then the replaceable cover plate 6 is moved forward so that the slot 10 on the buckle 7 is engaged with the front edge of the slot 9, thereby completing the longitudinal locking of the replaceable cover plate 6 and generating an active interval 11 between the rear end of the replaceable cover plate 6 and the rear end of the installation slot 5. At this time, trigger the locking button 36 so that the controller 35 controls the power source 13 to drive the locking block 12 to insert into the active interval 11, thereby achieving the locking of the replaceable cover plate 6.

[0056] When disassembling the replaceable cover plate 6, first trigger the unlocking button 37 so that the controller 35 controls the power source 13 to drive the locking block 12 to withdraw from the movable interval 11, thereby releasing the lock of the replaceable cover plate 6. Then, the above-mentioned installation process is reversed to remove the replaceable cover plate 6.

[0057] When the replaceable cover plate 6 is installed, the automatic transport vehicle for chemical fiber yarn cakes can be put into use. When the yarn cake tube 4 receives the yarn cake 40, the motor 18 is first controlled by the controller 35 to operate, so as to drive the lead screw 15 to rotate circumferentially, thereby driving the nut 16 and the push block 14 connected to the nut 16 to retreat along the length direction of the yarn cake tube 4. After the retreat is completed, the yarn cake 40 can be received by the yarn cake tube 4. When the yarn cake 40 is output, the motor 18 is controlled by the controller 35 to run in the reverse direction, so as to drive the lead screw 15 to rotate in the reverse direction, thereby driving the nut 16 and the push block 14 connected to the nut 16 to move forward along the length direction of the yarn cake tube 4, so as to push away the yarn cake 40 hung on the yarn cake tube 4. When the yarn cake 40 slides on the yarn cake tube 4, the upper surface of the replaceable cover plate 6 can play a supporting role, thereby extending the service life of the yarn cake tube 4.

[0058] During the operation of the nut 16, the guide wheel 22 on the guide sleeve 20 can play a supporting and guiding role. At the same time, the pressure wheel 25 located at the top of the guide sleeve 20 can lift the sunken part of the replaceable cover plate 6 to restore the replaceable cover plate 6 as much as possible, thereby extending the service life of the replaceable cover plate 6.

[0059] In the process of lifting the sunken part of the replaceable cover plate 6, the reaction force generated by the pressure wheel 25 can drive the mounting block 26 to press down, so that the pressure value between the mounting block 26 and the plug-in slot 27 rises to the pressure threshold and is captured by the pressure detection unit 31. The measured pressure value can be sent to the controller 35 in the form of a pressure detection signal through the control unit 32, the wireless transmitting unit 33, and the wireless receiving unit 34 in sequence. When the controller 35 detects that the pressure value corresponding to the pressure detection signal is greater than the pressure threshold, it can count once. When the metering times reaches the times threshold, it means that the times that the replaceable cover plate 6 is deformed due to the squeezing of the wire cake 40 has reached the upper limit. At this time, the controller 35 can cut off the motor 18 to stop the screw 15 and the nut 16 from running. Then, the controller 35 controls the power source 13 to run through the solenoid valve 49 to drive the locking block 12 to withdraw from the active interval 11, thereby releasing the lock of the replaceable cover plate 6, and at the same time controls the prompt unit 38 to emit a warning sound to remind the staff to replace the replaceable cover plate 6 in time. After the staff removes the remaining yarn cakes 40 on the yarn cake tube 4, the replaceable cover plate 6 can be disassembled and replaced.
