Description

Technical Field

[0001] The utility model relates to the technical field of chemical fiber production and manufacturing, in particular to a yarn cake transporter. Background Art

[0002] A winding machine is a device that winds chemical fibers into yarn cakes and is widely used in the textile industry. After the yarn cakes are produced, they need to be transported. To improve transportation efficiency, the invention application with publication number CN107826869A discloses a doffing machine, comprising a car body with an opening for the entry and exit of the yarn cakes, at least one yarn cake tube for inserting the yarn cakes slidingly inserted into the car body, and a drive mechanism corresponding to the yarn cake tube and used to drive the yarn cake tube through the opening. When the invention is used, the car body moves to the discharge port of the winding machine, and the yarn cake tube in the car body of the invention is aligned with the yarn cake tube in the discharge port of the winding machine. The winding machine will push the yarn cake from the yarn cake tube in the discharge port to the yarn cake tube of the invention. After the yarn cake is pushed, the invention will transport the inserted yarn cake to the hanging rack for hanging.

[0003] Although the above-mentioned doffing car can improve the efficiency of handling bobbin, it is affected by various environmental factors in the winding workshop, and its actual driving route will deviate from the pre-planned route to a certain extent, resulting in the bobbin tube on the doffing car being unable to be completely aligned with the bobbin tube in the winding machine outlet. This will significantly reduce the efficiency and smoothness of the bobbin when it is unloaded from the machine, and in severe cases, it may even cause the bobbin to fail to be unloaded from the machine. Therefore, there is still room for improvement. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a bobbin transport vehicle, which can realize secondary deviation correction of bobbin tubes, thereby improving the efficiency, accuracy and smoothness of the bobbin transport vehicle in receiving and unloading bobbin.

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

[0006] A bobbin transport vehicle comprises an automatic guided vehicle. A workbench is provided on one side of the automatic guided vehicle. The workbench is provided with at least one bobbin tube and a three-axis motion platform connected to the bobbin tube.

[0007] With the above solution, when the automatic guided vehicle runs to the discharge port of the winding machine or the front side of the hanging rack, the three-axis motion platform can perform secondary deviation correction on the bobbin tube so that the bobbin tube on the automatic guided vehicle can be completely aligned with the bobbin tube on the winding machine or the bobbin tube on the hanging rack, thereby improving the efficiency, accuracy and smoothness of the bobbin handling vehicle in receiving and unloading bobbin.

[0008] Preferably, the three-axis motion platform is a three-axis servo platform.

[0009] With the above solution, the three-axis servo platform is driven by a servo motor, which can effectively improve the stability and accuracy of the bobbin tube during secondary deviation correction.

[0011] Preferably, the cake pushing mechanism includes a push block arranged outside the cake tube to form a thrust on the end face of the cake, and a drive assembly connected to the push block to drive the push block to move linearly along the length direction of the cake tube.

[0012] By adopting the above solution, the driving assembly drives the push block forward, so that the yarn cake string on the yarn cake tube can be pushed away from the yarn cake tube, thereby completing the unloading of the yarn cake.

[0013] Preferably, the drive assembly includes a ball screw pair arranged in the bobbin tube, the ball screw pair includes a screw and a nut threadedly engaged with the screw, the screw is rotatably passed through the bobbin tube, the nut is connected to the push block through a connecting piece, and the side wall of the bobbin tube is provided with an avoidance groove along its own length direction for the connecting piece to slide through, and a driving part connected to the screw to drive the screw to rotate circumferentially is provided on the drive seat.

[0014] By adopting the above solution, the driving part drives the screw to rotate, which can drive the nut on the ball screw pair forward or backward, and drive the push block forward and backward through the connecting piece, thereby improving the stability and accuracy of the bobbin transport vehicle when receiving or unloading bobbin.

[0015] Preferably, both ends of the lead screw are rotatably inserted into opposite positions of the drive seat and the bobbin tube, and bearings are provided at both ends.

[0016] By adopting the above solution, the bearing can improve the stability and smoothness of the screw during operation.

[0017] Preferably, the driving portion includes a servo motor disposed on a driving seat, one end of the lead screw close to the driving seat extends beyond the outer wall of the driving seat and the extending portion is connected to the output shaft of the servo motor via a belt transmission mechanism.

[0018] By adopting the above solution, the driving unit can stably drive the ball screw pair to operate and ensure the accuracy of the operation of the ball screw pair.

[0019] Preferably, a guide rod is passed through the spool tube, a guide block is provided on the nut, and a guide groove is provided on the guide block for slidingly engaging with the guide rod so that the guide block can move linearly along the guide rod.

[0021] Preferably, the push block has an arc-shaped cross section and is arranged around the outside of the bobbin tube.

[0022] By adopting the above scheme, the cross section of the push block is set to an arc shape, which can not only increase the contact area between the push block and the silk cake, but also make the thrust generated by the push block evenly distributed on the end face of the silk cake, thereby further improving the stability and accuracy of the silk cake when pushing.

[0023] Due to the adoption of the above technical solution, the utility model has significant technical effects: when the automatic guided vehicle runs to the discharge port of the winding machine or the front side of the hanging rack, the three-axis motion platform can perform secondary deviation correction on the bobbin tube, so that the bobbin tube on the automatic guided vehicle can be completely aligned with the bobbin tube on the winding machine or the bobbin tube on the hanging rack, thereby improving the efficiency, accuracy and smoothness of the bobbin transport vehicle in receiving and unloading the bobbin.

[0035] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0036] like Figures 1 to 4 As shown, a bobbin transport vehicle disclosed in this embodiment includes an automatic guided vehicle 1, a workbench 2 is fixedly provided on the front side of the automatic guided vehicle 1, and at least one horizontally arranged bobbin tube 3 and a three-axis motion platform 4 connected to the bobbin tube 3 are provided on the workbench 2. The three-axis motion platform 4 is a three-axis servo platform, and its execution end is provided with a drive seat 5 for connecting to the bobbin tube 3. The drive seat 5 is provided with a bobbin pushing mechanism for pushing the bobbin 19 away from the bobbin tube 3. Specifically, the bobbin pushing mechanism includes a push block 6 arranged on the outside of the bobbin tube 3 to form a thrust on the end face of the bobbin 19, and a drive assembly connected to the push block 6 to drive the push block 6 to perform a linear motion along the length direction of the bobbin tube 3. The push block 6 has an arc-shaped cross section and is arranged around the outside of the bobbin tube 3, thereby improving the stability and accuracy of the push block 6 when pushing the bobbin 19.

[0037] like Figure 5 and Figure 6 As shown, in this embodiment, the drive assembly includes a ball screw pair disposed in the bobbin tube 3, the ball screw pair including a lead screw 7 and a nut 8 threadedly engaged with the lead screw 7, the lead screw 7 rotatably passing through the bobbin tube 3, the nut 8 being fixedly connected to the push block 6 via a connector 9, and the side wall of the bobbin tube 3 is provided with an avoidance groove 10 along its length for the connector 9 to slide through, thereby preventing the connector 9 from being obstructed by the wall of the bobbin tube 3 during movement. A drive portion 11 connected to the lead screw 7 to drive the lead screw 7 to rotate circumferentially is provided on the drive seat 5. The drive portion 11 includes a servo motor 13 fixedly disposed on the drive seat 5. The end of the lead screw 7 near the drive seat 5 protrudes from the outer wall of the drive seat 5, and the protruding portion is connected to the output shaft 15 of the servo motor 13 via a belt transmission mechanism 14.

[0038] like Figure 7 and Figure 8 As shown, in order to ensure the stability of the installation of the screw 7 and the smoothness of operation, the two ends of the screw 7 are respectively rotated and penetrated at opposite positions of the driving seat 5 and the bobbin tube 3, and bearings 12 are provided at both ends.

[0039] like Figure 9 and Figure 10 As shown, in order to further improve the operating accuracy and smoothness of the push block 6, a cylindrical guide rod 16 is passed through the bobbin tube 3, and a guide block 17 is fixedly provided on the nut 8. The guide block 17 is provided with a guide groove 18 that is slidably connected to the guide rod 16 so that the guide block 17 can move linearly along the guide rod 16. The cross-section of the guide groove 18 is circular, which can effectively improve the fit between the guide groove 18 and the guide rod 16.

[0040] The specific working principle is as follows:

[0041] When the automatic guided vehicle 1 runs to the discharge port of the winding machine (not shown) or the front side of the hanging rack (not shown), the three-axis motion platform 4 can drive the bobbin tube 3 on the workbench 2 to translate in the X, Y, and Z directions, thereby completing the secondary deviation correction of the bobbin tube 3, so that the bobbin tube 3 on the bobbin transport vehicle can be fully aligned with the bobbin tube on the winding machine or the hanging rack (not shown), thereby improving the efficiency, accuracy, and smoothness of unloading the bobbin 19 from the machine.

[0042] When the winding machine (not shown) outputs the bobbin 19, the servo motor 13 on the automatic guided vehicle 1 drives the lead screw 7 to rotate forward through the belt transmission mechanism 14, thereby driving the nut 8, the connecting piece 9 and the push block 6 to retreat, so that the bobbin 19 can smoothly enter the bobbin tube 3.

[0043] When the bobbin tube 3 is fully loaded with bobbin cakes 19, the automated guided vehicle 1 can transport the bobbin string to the front of a hanger (not shown). After the bobbin tube 3 undergoes secondary deviation correction, the servo motor 13 drives the lead screw 7 through the belt drive mechanism 14 to rotate in the opposite direction, thereby driving the nut 8, connector 9, and push block 6 forward. The push block 6 then pushes the bobbin cakes 19 from the bobbin tube 3 one by one into the bobbin tube on the hanger (not shown), completing the unloading of the bobbin cakes 19.

[0044] like Figure 1 As shown, in order to improve the accuracy of secondary deviation correction, a visual detection sensor 20 can be set at the end of the bobbin tube 3 of the bobbin transport vehicle. The above control process can be implemented with the help of a PLC built-in program or an equivalent analog circuit, which is common knowledge in the field and will not be described here.
