[0002] The drawframe and the roving frame are consecutive process sections in the spinning industry. The drawframe produces sliver cans filled with sliver for use by the roving frame. After the roving frame uses up the sliver in the sliver can filled with sliver, it returns the empty can to the drawframe to continue filling with sliver. At present, the transportation of sliver cans between the roving frame process and the drawframe process entirely relies on manual transportation, which not only has a high labor intensity and high labor cost, but also has low transportation efficiency.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Example 1

[0038] This embodiment provides a conveyor line, such as Figures 1 to 15 As shown, it includes a transport vehicle module and a double track module;

[0039] The transport vehicle module includes a mother vehicle 1 and a child vehicle 2. Both the mother vehicle 1 and the child vehicle 2 move in a straight line, and the moving paths of the mother vehicle 1 and the child vehicle 2 are perpendicular and intersecting. The mother vehicle 1 is used to carry the child vehicle 2. When the child vehicle 2 and the mother vehicle 1 intersect in the moving paths, the mother vehicle 1 can carry the child vehicle 2 and move along the moving path of the mother vehicle 1 with the child vehicle 2. A lifting platform 14 that can be raised and lowered is provided on the child vehicle 2, and the lifting platform 14 is used to place a carrier. The lifting platform 14 has a platform width perpendicular to the moving path of the child vehicle 2, and the carrier has a carrier width perpendicular to the moving path of the child vehicle 2, and the carrier width is greater than the platform width.

[0040] The double-track module includes a supply part and an inventory part, and the supply part and the inventory part are respectively arranged on both sides of the moving path of the mother vehicle 1. The inventory part includes a temporary storage double track 3 and an empty cargo double track 4, and the temporary storage double track 3 and the empty cargo double track 4 are arranged along the moving path of the mother vehicle 1. The supply part includes a conveying double track 5 and a return double track 6, and the conveying double track 5 and the return double track 6 are arranged in parallel along the moving path of the mother vehicle 1. The conveying double track 5 is used to receive fully loaded load-carrying utensils, and the return double track 6 is used to deliver empty load-carrying utensils. The conveying double track 5 and the return double track 6 are both provided with a conveying mechanism that can transport along the double track direction, which is used to transport load-carrying utensils. The extension directions of the temporary storage double track 3, the empty cargo double track 4, the conveying double track 5 and the return double track 6 are all parallel to the moving path of the sub-vehicle 2. The distance between the double rails of the temporary storage double rail 3, the empty cargo double rail 4, the conveying double rail 5 and the return double rail 6 is between the platform width and the carrier width, that is, larger than the platform width but smaller than the carrier width, so that the load-carrying device can be placed on the double rails, and the sub-carriage 2 can move within the distance between the double rails. The track surface heights of the temporary storage double rail 3, the empty cargo double rail 4, the conveying double rail 5 and the return double rail 6 are between the initial height and the maximum height of the lifting platform 14, that is, the lifting platform 14 can be raised to a height above the track surface, and the load-carrying device can be lifted up to make it leave the double rails, and then the load-carrying device can be moved by the trolley, and the lifting platform 14 can be lowered below the track surface after being lowered, so that the load-carrying device can be placed on the double rails without affecting the movement of the sub-carriage 2. Preferably, the load-carrying device can be a barreled device, a frame-type device, a box-type device, a tray-type device, etc.

[0041] Working principle:

[0042] The cooperation modes of the mother vehicle 1, the child vehicle 2, the temporary storage double track 3, the empty cargo double track 4, the conveying double track 5 and the return double track 6 are diverse. The following provides a most basic operation process for reference, which does not mean that only the following motion modes can be selected: First, the mother vehicle 1 carries the child vehicle 2 and moves along its moving path to the conveying double track 5. The child vehicle 2 detaches from the mother vehicle 1 and moves between the two tracks of the conveying double track 5. The conveying double track 5 receives the fully loaded load-carrying appliance, and under the action of the conveying mechanism, transports the load-carrying appliance above the child vehicle 2. The lifting platform 14 of the child vehicle 2 rises to lift the fully loaded load-carrying appliance. After being lifted, the child vehicle 2 drives away with the load-carrying appliance, and the mother vehicle 1 welcomes the child vehicle 2, and the lifting platform 14 descends; Then, the mother vehicle 1 carries the child vehicle 2 and moves along its moving path to the temporary storage double track 3. The child vehicle 2 drives towards two adjacent temporary storage double tracks 3. During the process of driving towards the temporary storage double track 3, the lifting platform 14 lifts the fully loaded load-carrying appliance so that the bottom of the fully loaded load-carrying appliance is higher than the track surface of the temporary storage double track 3. Then the child vehicle 2 drives into the temporary storage double track 3. After arriving, the lifting platform 14 descends below the track surface, and the fully loaded load-carrying appliance is placed on the track surface. The child vehicle 2 drives away from the temporary storage double track 3, and the mother vehicle 1 welcomes the child vehicle 2; Then, the mother vehicle 1 carries the child vehicle 2 and moves along its moving path to the empty cargo double track 4. The child vehicle 2 drives into the empty cargo double track 4, and the lifting platform 14 lifts the empty load-carrying appliance. The child vehicle 2 drives away from the empty cargo double track 4 with the empty load-carrying appliance, and the mother vehicle 1 welcomes the child vehicle 2; Then, the mother vehicle 1 drives the child vehicle 2 along its moving path to the return double track 6. The child vehicle 2 drives into the return double track 6, and the lifting platform 14 descends, and the empty load-carrying appliance is sent out under the conveying mechanism. Next, repeating the above process can realize the automatic conveying and return of the load-carrying appliance. This conveying scheme is mature, complete, and has high conveying efficiency. It can also be adjusted accordingly according to needs to flexibly, variably, stably, and quickly realize functions such as the supply, exchange, and scheduling of empty / full load-carrying appliances. Moreover, the temporary storage double track 3, the empty cargo double track 4, the conveying double track 5 and the return double track 6 do not affect each other and are arranged in an orderly manner.

[0043] In this embodiment, as Figures 1 to 15 shown, it includes at least two child vehicles 2. The cooperation modes of multiple child vehicles 2 can be set according to the actual situation and have multiple cooperation modes. One of them is that multiple child vehicles 2 work continuously and alternately, and the other is that one child vehicle 2 is mainly used for transportation, and the other child vehicles 2 only transport between the temporary storage double track 3 and the empty cargo double track 4. Of course, there are many other operation modes, which will not be listed one by one here.

[0044] Multiple sub-vehicles 2 perform continuous alternating operations. Taking two sub-vehicles as an example: After the mother vehicle 1 takes the first sub-vehicle 2 to the conveying double track 5, immediately the mother vehicle 1 goes to pick up the second sub-vehicle 2. At this time, the first sub-vehicle 2 goes to receive the fully loaded carrying appliance. The second sub-vehicle 2 transports the empty carrying appliance to the mother vehicle 1. Then the mother vehicle 1 transports the second sub-vehicle 2 to the empty cargo double track 4. Immediately, the mother vehicle 1 goes to pick up the first sub-vehicle 2. At this time, the second sub-vehicle 2 sends the empty carrying appliance to the empty cargo double track 4. The mother vehicle 1 sends the first sub-vehicle 2 to the temporary storage double track 3. Then the mother vehicle 1 follows the second sub-vehicle 2 to the conveying double track 5, picks up the first sub-vehicle 2 and goes to the empty cargo double track 4, and works in a cycle. When there are more than two sub-vehicles 2, the same can be deduced by analogy.

[0045] One sub-vehicle 2 is mainly for transportation, and the other sub-vehicles 2 only transport between the temporary storage double track 3 and the empty cargo double track 4. Taking two sub-vehicles as an example: The first sub-vehicle 2 and the mother vehicle 1 cooperate to be responsible for sending the fully loaded carrying appliance on the conveying double track 5 to the track entrance of the temporary storage double track 3. The second sub-vehicle 2 is responsible for transporting the fully loaded carrying appliance at the track entrance to the end of the temporary storage double track 3 for arrangement. Then the second sub-vehicle 2 cooperates with the mother vehicle 1 to move from the temporary storage double track 3 to the empty cargo double track 4, and transports the empty carrying appliance to the track entrance of the empty cargo double track 4. Then the first sub-vehicle 2 and the mother vehicle 1 cooperate to receive the empty carrying appliance at the track entrance of the empty cargo double track 4, and then send it to the return double track 6.

[0046] One sub-vehicle 2 is mainly for transportation, and the other sub-vehicles 2 only transport between the temporary storage double track 3 and the empty cargo double track 4. Taking three sub-vehicles as an example: The first sub-vehicle 2 and the mother vehicle 1 cooperate to be responsible for sending the fully loaded carrying appliance on the conveying double track 5 to the track entrance of the temporary storage double track 3. The second sub-vehicle 2 is responsible for transporting the fully loaded carrying appliance at the track entrance to the end of the temporary storage double track 3 for arrangement. If there are multiple temporary storage double tracks 3, the second sub-vehicle 2 can also cooperate with the mother vehicle 1 to transfer between multiple temporary storage double tracks 3. The third sub-vehicle 2 is responsible for transporting the empty carrying appliances arranged on the empty cargo double track 4 to the track entrance of the empty cargo double track 4. Then the first sub-vehicle 2 and the mother vehicle 1 cooperate to receive the empty carrying appliance at the track entrance of the empty cargo double track 4, and then send it to the return double track 6. If there are multiple empty cargo double tracks 4, the third sub-vehicle 2 can also cooperate with the mother vehicle 1 to transfer between multiple empty cargo double tracks 4.

[0047] Further, in this embodiment, as Figures 1 to 15 shown, the number of the temporary storage double track 3 and the empty cargo double track 4 can be set according to needs. There are two arrangement methods for the temporary storage double track 3 and the empty cargo double track 4. One is that the temporary storage double track 3 and the empty cargo double track 4 are arranged at intervals, that is, they are arranged along the moving path of the mother vehicle 1 in the way of temporary storage double track 3 - empty cargo double track 4 - temporary storage double track 3 - empty cargo double track 4. The other is to arrange them by area, that is, the temporary storage double tracks 3 are concentrated in one area, and the empty cargo double tracks 4 are stored in one area, that is, they are arranged along the moving path of the mother vehicle 1 in the way of temporary storage double track 3 - temporary storage double track 3 - empty cargo double track 4 - empty cargo double track 4.

[0048] In this embodiment, asFigures 1 to 15 As shown, the conveying mechanism on the conveying double track 5 and the return double track 6 is a conveying belt 25 or a conveying chain plate. That is, a conveying belt 25 is respectively provided on one side of the double tracks of the conveying double track 5 and the return double track 6 to drive the object-carrying device.

[0049] Furthermore, in this embodiment, a method for a mother vehicle 1 to transport a sub-vehicle 2 is provided, such as Figures 1 to 15 As shown, a lifting mechanism is provided on the two side walls of the sub-carriage 2, and the lifting mechanism includes a lifting part that can be raised and lowered, and there is a first preset height difference between the highest position of the lifting part and the ground, and there is a second preset height difference between the lowest position of the lifting part and the ground, and the second preset height difference is lower than the first preset height difference. A sub-carriage entrance 11 is provided on the mother car 1 for the sub-carriage 2 to enter. A parking area for the sub-carriage 2 to stop is provided in the sub-carriage entrance 11 along the moving path of the sub-carriage 2, and supporting bosses 12 are provided on the two side walls of the parking area. The supporting bosses 12 are located on the descending path of the lifting part of the parked sub-carriage 2, and there is a third preset height difference between the supporting bosses 12 and the ground. The third preset height difference is between the first preset height difference and the second preset height difference, that is, the third preset height difference is greater than the second preset height difference, but less than the first preset height difference. The purpose of this setting is that when the jacking parts on the two side walls of the sub-trolley 2 descend, the jacking parts will contact the table surface of the supporting boss 12, and then as the jacking parts descend to the lowest point, because the lowest point of the jacking parts is lower than the table surface of the supporting boss 12, the sub-trolley 2 can only be lifted in the reverse direction to make the sub-trolley 2 leave the ground, which is conducive to the movement of the mother car 1 with the sub-trolley 2.

[0050] Further, in this embodiment, if Figures 1 to 15 As shown, a conical groove 13 area is provided on the supporting boss 12 corresponding to the position of the wheel 17 of the sub-carriage 2 to ensure the parking stability of the sub-carriage 2.

[0051] In this embodiment, Figures 1 to 15 As shown, the lifting platform 14 is vertically slidably connected to the sub-carriage 2, and the lifting platform 14 is located on the lifting path of the lifting part. The lifting part can lift the lifting platform 14 to achieve the lifting of the lifting platform 14 when it rises, and can lower the lifting platform 14 when it falls. If the sub-carriage 2 is located in the sub-carriage entrance 11, the lifting part continues to descend and contacts the supporting boss 12, and the sub-carriage 2 can also be separated from the ground. The lifting and lowering of the lifting platform 14 and the separation and contact with the ground of the sub-carriage 2 are achieved through a lifting part.

[0052] In this embodiment, Figures 1 to 15As shown in the figure, the jacking mechanism includes a cam 15, and the jacking part is the convex part of the cam 15. The cam 15 is rotatably connected to the two side walls of the sub-vehicle 2. When the convex part of the cam 15 rotates upward, the lifting platform 14 can be jacked up. When it rotates downward and contacts the supporting boss 12, the sub-vehicle 2 can be jacked up. Preferably, cross beams are provided on the two side walls of the sub-vehicle 2, and accommodation grooves penetrating up and down are provided on the cross beams, and the cam 15 is arranged in the accommodation grooves.

[0053] Further, in this embodiment, as Figures 1 to 15 shown, guide wheels 16 are provided on the two side walls of the sub-vehicle 2. The guide wheels 16 are used to contact the side walls of the double rails. The guide wheels 16 cooperate with the double rails to realize the guiding of the sub-vehicle 2.

[0054] In this embodiment, as Figures 1 to 15 shown, the main vehicle 1 with a sub-vehicle entrance 11 is integrally in the shape of a door. Wheels 17 are provided at the bottom of the main vehicle 1 for driving. In order to ensure the straight-line running of the main vehicle 1, a sky rack guide rail 22 can be provided, and guide wheels 23 are provided at the top of the main vehicle 1 to cooperate with the sky rack guide rail 22 for guiding.

[0055] Further, in this embodiment, as Figures 1 to 15 shown, the main vehicle 1 adopts polyurethane wheels 17, which are stable and wear-resistant. Using lightweight materials reduces the weight of the main vehicle body on the premise of meeting the requirements of structural strength and safety, and can ensure that the main vehicle 1 provides a load capacity of more than 300KG.

[0056] In this embodiment, as Figures 1 to 15 shown, ultrasonic sensors are provided on both the main vehicle 1 and the sub-vehicle 2, and stop moving when encountering obstacles.

[0057] In this embodiment, as Figures 1 to 15 shown, the main vehicle 1 and the sub-vehicle 2 adopt servo control. When the main vehicle 1 cooperates with the sky rack guide rail 22, it can be powered by a sliding contact line, and the main vehicle 1 can be fully charged during operation.

[0058] Embodiment 2

[0059] This embodiment provides a sliver can conveying system. As Figures 1 to 15 shown, it includes the conveying line in Embodiment 1. The load-carrying appliance of the conveying line is a sliver can 18. When taking and placing, the sliver can 18 is vertically arranged on the sub-vehicle 2. The loading quantity on the sub-vehicle 2 is set according to needs. Usually, it is more practical to design to be able to place two sliver cans 18 at the same time. The conveying double rails 5 and the return double rails 6 of the conveying line respectively correspond to the sliver can outlet 9 and the sliver can inlet 10 of the drawing frame 8. The temporary storage double rails 3 and the empty cargo double rails 4 of the conveying line are located in the inventory area of the roving frame 7.

[0060] Working principle:

[0061] The drawframe 8 produces full bale cans 18, which enter the conveying double track 5 from the bale can outlet 9, and then can be conveyed to the temporary storage double track 3 by the cooperation of the mother vehicle 1 and the son vehicle 2. The bale can 18 can be sent to the roving frame through an additional picking mechanism. Then the remaining empty bale cans 18 are placed on the empty goods double track 4 by the picking mechanism. The mother vehicle 1 and the son vehicle 2 cooperate to convey the empty bale cans 18 on the empty goods double track 4 to the return double track 6, and then are conveyed by the return double track 6 to the bale can inlet 10 and produced again by the drawframe 8. This bale can 18 conveying scheme is mature, complete, and has high conveying efficiency. It can also be adjusted accordingly according to needs to flexibly, variably, stably, and quickly realize functions such as the supply, exchange, and scheduling of empty / full load appliances. Moreover, the temporary storage double track 3, the empty goods double track 4, the conveying double track 5, and the return double track 6 do not affect each other and are arranged in an orderly manner.

[0062] In this embodiment, as Figures 1 to 15 shown, a fixture is installed inside the son vehicle inlet 11 of the conveying line. The fixture includes two symmetrically arranged clamping jaws 19, and the two clamping jaws 19 can close. Each clamping jaw 19 is provided with two arc-shaped clamping areas 20. After the two clamping jaws 19 close, the two arc-shaped clamping areas 20 on the two clamping jaws 19 can just clamp the two bale cans 18 on the son vehicle 2. In order to ensure that the two bale cans 18 and the two arc-shaped clamping areas 20 are exactly opposite: First, the two bale cans 18 need to be accurately placed at the two bale can placement areas of the son vehicle 2; Second, it is necessary to ensure that the son vehicle 2 accurately stops at the parking area. For the first condition, a photoelectric sensor 24 can be set at the placement area of the son vehicle 2 to sense whether the bale can 18 is exactly above the placement area, and then the lifting platform 14 is raised. For the second condition, a Hall sensor can be set on the son vehicle 2, and a magnetic material locator for the Hall sensor to sense is set at the parking area.

[0063] In this embodiment, as Figures 1 to 15 shown, a buffer wheel 21 is provided inside the arc-shaped clamping area 20.

[0064] In this embodiment, as Figures 1 to 15 shown, the center of gravity of the bale can 18 is high, so the chassis of the son vehicle 2 needs to be designed lower to ensure stable transportation.

[0065] In this embodiment, as Figures 1 to 15As shown in the figure, the sliver can transportation system is scheduled and controlled by the control system. The control system includes a control module, a main control module, and a scheduling module. The control module controls the forward and backward movement, jacking, and charging of the main vehicle 1 and the sub-vehicle 2. The scheduling module schedules the main vehicle 1 and the sub-vehicle 2 to pick up and place empty / full sliver cans 18 at corresponding positions according to the production status of the drawing frame 8 and the roving frame 7. The main control module controls functions such as on-site equipment, communication, power supply, and navigation. The core of the control system is the PLC controller, various sensors, lidar, vision system, and wireless communication equipment. The various sensors, lidar, and vision system enable the flexible operation and precise positioning of the main vehicle 1 and the sub-vehicle 2, etc. The wireless communication equipment is used for wireless communication and data exchange between the main control system and the PLC controllers of the sub-vehicle, the main vehicle, the drawing frame 8, and the roving frame 7. Further, the main vehicle can also adopt the QR code positioning technology. By reading the QR code with a reader, the positioning accuracy is ±0.5 mm, which can ensure the accurate lane-changing position of the sub-vehicle 2.

[0066] In this embodiment, as Figures 1 to 15 shown, the sliver can transportation system uses three sub-vehicles 2. The first sub-vehicle 2 is the main moving vehicle. The second sub-vehicle 2 moves between the temporary storage double tracks 3 for arranging full cans. The third sub-vehicle 2 moves between the empty cargo double tracks 4 for picking up and delivering empty cans. Specifically, when the drawing frame 8 produces full cans, the main vehicle 1 and the first sub-vehicle 2 transport them to the inventory area of the roving frame 7. The second vehicle in the inventory area is responsible for arranging the full cans. After the roving frame 7 finishes production, the empty cans are transported out one by one by the third vehicle. The main vehicle 1 and the first sub-vehicle 2 transport the empty cans to the drawing frame 8 to form a production closed loop.

[0067] I. The overall working process is as follows:

[0068] (1) After the drawing frame 8 is full of cans, it is transported to the conveyor belt 25 of the transport double track 5 by the self-transport mechanism of the sliver can outlet 9, which can accommodate two full cans;

[0069] (2) After the control system receives the occupancy signal at the can outlet position, it schedules the main vehicle 1. The main vehicle 1 carries the first sub-vehicle 2 and runs to the transport double track 5. The first sub-vehicle 2 grabs two full cans each time and returns to the main vehicle 1;

[0070] (3) The main vehicle 1 is scheduled by the control system to run to the inventory double track. The first sub-vehicle 2 transports the two full cans to the can positions on the inventory double track, and then the second sub-vehicle 2 transports the full cans to the in-place position;

[0071] (4) Repeat the above steps until all the can positions on this inventory double track are full and in place;

[0072] (5) When the empty cylinders on the empty goods double track are full, the control system sends a signal to pick up the empty cylinders to the mother vehicle 1. The mother vehicle 1 runs to the empty goods double track, and the third sub-vehicle 2 grabs two empty cylinders each time and transports them to the cylinder outlet position of the empty goods double track. Then, the first sub-vehicle 2 cooperates with the mother vehicle 1 to send the empty cylinders to the return double track 6. The return double track 6 sends the empty cylinders into the sliver can inlet 10, and the sliver can inlet 10 transports them to the drawing frame 8 through its own transport mechanism.

[0073] II. The signal processing process is as follows:

[0074] Control module, main control module, scheduling module

[0075] (1) After the drawing frame 8 produces two full cylinders, the main control module communicates with the scheduling module wirelessly to inform the full cylinder information (there are two positions where the drawing frame 8 produces full cylinders).

[0076] (2) After the scheduling module receives the full cylinder information of the drawing frame 8, it analyzes the status of the first sub-vehicle 2 and the mother vehicle 1. If the status of the first sub-vehicle 2 and the mother vehicle 1 is busy at this time, the main control module queues up this task. If the status of the first sub-vehicle 2 and the mother vehicle 1 is idle at this time, the scheduling module communicates with the control module wirelessly to schedule the first sub-vehicle 2 and the mother vehicle 1 to go to the position where the drawing frame 8 produces full cylinders to carry the full cylinders (two at a time); after the main control module communicates with the roving frame 7, it allocates the inventory double track that needs full cylinders according to the status of the roving frame 7. The first sub-vehicle 2 and the mother vehicle 1 carry the full cylinders to the corresponding inventory double track and place the full cylinders at the front end position of the inventory double track.

[0077] (3) The second vehicle in the corresponding inventory double track transports the full cylinders carried by the first sub-vehicle 2 and the mother vehicle 1 to the end of the inventory double track for arrangement, and the main control module records the number and status of the sliver cans.

[0078] (4) Repeat the above steps 1 - 3 until the number of sliver cans in this inventory double track reaches the specified quantity (depending on the type of the roving frame 7, the specified number of sliver cans per track is between 24 and 36).

[0079] (5) The main control module scans the empty goods double track 4 of the roving frame 7 and sends an instruction to the third sub-vehicle 2 in the empty goods double track 4. The third sub-vehicle 2 transports the empty cylinders to the front end of the track in the order of empty cylinder arrangement.

[0080] (6) After the scheduling module receives the information that the empty cylinders have arrived, it analyzes the status of the first sub-vehicle 2 and the mother vehicle 1. If the status of the first sub-vehicle 2 and the mother vehicle 1 is busy at this time, the scheduling module queues up this task.

[0081] (7) If the status of the first sub-vehicle 2 and the mother vehicle 1 is idle at this time, the main control module contacts the scheduling module through wireless communication. The scheduling module schedules the status of the first sub-vehicle 2 and the mother vehicle 1 to move to the position corresponding to the empty and full bobbin double track 4, and the first sub-vehicle 2 and the mother vehicle 1 carry empty bobbins (two at a time); after the main control module communicates with the drawing frame 8, it allocates the return double track 6 according to the empty bobbin demand of the drawing frame 8. Each drawing frame 8 can be equipped with two return double tracks 6. The first sub-vehicle 2 and the mother vehicle 1 carry the empty bobbins to the corresponding return double track 6 and place the empty bobbins at the front end position of the return double track 6. The return double track 6 drives the conveyor belt 25 through the motor to transport the empty bobbins into the sliver bobbin inlet 10 of the drawing frame 8, and the drawing frame 8 conducts production;

[0082] (8) Repeat steps 5-7 to continuously supply empty bobbins to the drawing frame 8 to form an uninterrupted cyclic operation.

[0083] Under the control of software operation, control the actions, positioning and operation scheduling of the above-mentioned units, use sensors to collect feedback information, and conduct human-machine interaction with users through the human-machine interface and buttons. The mother vehicle 1 and the sub-vehicle 2 can achieve a maximum driving speed of 60 meters per minute, and can carry two sliver bobbins 18 each time. Each light-load vehicle system can meet the sliver bobbin 18 conveying work between the drawing frame 8 process and the roving frame 7 process in a workshop with a scale of 30,000 spindles, and can replace 2-3 person-times of manual labor per day.
