[0043] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope protected by the present invention.

[0044] The present invention provides a double-station shuttle car conveying system, including a ring track 6 and a double-station shuttle car 1 traveling on the ring track 6, wherein:

[0045] The double-station shuttle car 1 includes a front station on the front side in its advancing direction and a rear station on the rear side in the advancing direction;

[0046] The ring track 6 has a material entrance p4 and a material exit p3, and a rotary loading and unloading area p1 is provided on the circumferential side of the ring track 6;

[0047] The double-station shuttle car 1 circulates between the material entrance p4, the rotary loading and unloading area p1 and the material exit p3, and completes the rapid flow of materials through the cooperation between the front station and the rear station and the loading and unloading stations.

[0048] The double-station shuttle car 1 circulates between the material inlet p4, the rotary loading and unloading area p1, and the material outlet p3, and completes the rapid transfer of materials through the cooperation between the front station and the rear station and the loading and unloading stations. Compared with the existing method of simply increasing the number of shuttle cars in the loop-through system, the docking and cooperation between the double-station and the loading and unloading stations are completed through the scheduling of the double-station shuttle car 1, improving the loading and unloading efficiency and meeting the efficiency requirements of logistics transportation under high production capacity.

[0049] As Figure 1 shown, the specific embodiment of the present invention provides a double-station shuttle car conveying system applied to the drawing area of glass fiber manufacturing. The structure of the double-station shuttle car 1 is referred to Figure 2 , Figure 6 and Figure 7 . Figure 2 The arrow direction in

[0050] is the transplanting direction, and the traveling direction of the double-station shuttle car 1 is perpendicular to the arrow. The station of the double-station shuttle car 1 in the forward direction is called the front station, and the other station is called the rear station. Figure 1 and Figure 4 .

[0051] As an optional embodiment, the rotary loading and unloading area p1 includes a plurality of rotary tables 3 and a plurality of rotary docking stations to flexibly adjust the double-station shuttle car 1 according to the loading and unloading requirements and meet the logistics transfer requirements. The structure of the rotary table 3 is referred to

[0052] As an optional embodiment, the number of rotary loading and unloading areas p1 is two, and they are arranged on the inner and outer sides of the straight section of the annular track 6. Arranging them on the inner and outer sides of the straight section facilitates rapid loading and unloading. Figure 3 The top view structure of the transfer machine 2 is given,

[0053] As an optional embodiment, the double-station shuttle car 1 conveying system further includes a temporary storage area p2, and the temporary storage area p2 is located on one side of the annular track 6 between the rotary loading and unloading area p1 and the material outlet p3. Setting up the temporary storage area p2 provides a buffer space, improves the system flexibility, and has strong adaptability.

[0054] As Figure 8 shown, the present invention provides a scheduling method, which uses any of the above double-station shuttle car 1 conveying systems to schedule the shuttle car and transfer the materials. The method includes the following steps:

[0055] S1. Obtain the demand information of the double-station shuttle car 1;

[0056] S2. Control the double-station shuttle car 1 to reach the required station according to the demand information;

[0057] S3. Transfer the materials through the cooperation between the front station and the rear station of the double-station shuttle car 1 and the loading and unloading stations.

[0058] Through the scheduling of the double-station shuttle car 1, the docking and cooperation between the double-station and the loading and unloading stations are completed, improving the material loading and unloading efficiency.

[0059] As an optional implementation manner, as Figure 9 shown, step S3 includes:

[0060] S31. Transfer the material A from the material inlet p4 of the annular track 6 to the rear station of the double-station shuttle car 1.

[0061] S32. The double-station shuttle car 1 travels to the first required station in the rotary loading and unloading area p1, and the rotary table 3 transfers the material B to the front station of the double-station shuttle car 1 to complete loading.

[0062] S33. Align the rear station of the double-station shuttle car 1 with the just-vacated first required station, and transfer the material A to the first required station to complete unloading.

[0063] S34. The double-station shuttle car 1 travels along the annular track 6 to transfer the material B to the material outlet p3 of the annular track 6.

[0064] As an optional implementation manner, after step S33, if there is a second required station in the rotary loading and unloading area p1 in the forward direction of the double-station shuttle car 1, control the double-station shuttle car 1 to travel to align its rear station with the second required station to complete loading.

[0065] As an optional implementation manner, in step S1, determine whether two copies of the material A are required in the rotary loading and unloading area p1. If so, step S3 includes:

[0066] Transfer two copies of the material A from the material inlet p4 of the annular track 6 to the front station and the rear station of the double-station shuttle car 1 respectively.

[0067] The double-station shuttle car 1 transports two copies of the material A to two required stations in the rotary loading and unloading area p1.

[0068] The specific implementation manner of the present invention provides a scheduling method for a logistics conveying system in a glass fiber production drawing area. The general technological process is to transport the empty bobbin car 4 at the material inlet p4 of the drawing area to the rotary table 3 in the required wire dropping area, and transport the yarn cake car 5 on the rotary table 3 in the wire dropping area to the material out platform p3 in the wire dropping area. The scheduling method includes the following categories.

[0069] Scheduling method 1: As Figure 5As shown in the figure, the double-station shuttle car 1 picks up the empty bobbin car 4 at the rear station from the P4 area and runs to the turntable station of the yarn package car 5 that needs to be delivered in the P1 area (the longest waiting time). The front station of the shuttle car aligns with the turntable station, and the front station picks up the yarn package car 5. Then the shuttle car moves forward, and the rear station aligns with the just-vacated turntable station. The shuttle car sends the empty bobbin car 4 at the rear station to the turntable station, and the turntable station rotates to drop the yarn. The shuttle car transports the yarn package car 5 at the front station to the P3 area. The logistics conversion of the empty and full bobbin cars in the wire drawing area is completed. (For the detailed schematic diagram of the docking process between the turntable 3 and the double-station shuttle car 1, see the figure below.)

[0070] Scheduling method 2: To increase the operation efficiency, in the scheduling 1 algorithm, when the double-station shuttle car 1 completes the docking process between the turntable 3 and the double-station shuttle car 1 (one yarn package car 5 is picked up and one empty bobbin car 4 is delivered at the same turntable station), if there is still a signal from the turntable station that needs to deliver the yarn package car 5 in its forward direction, the shuttle car runs to the rear station and aligns with this turntable station to pick up the yarn package car 5. Then the two yarn package cars 5 are transported to the P3 area.

[0071] Scheduling method 3: Further, before the double-station shuttle car 1 arrives at the P4 area, the system judges whether there are two stations in the P1 area that need the empty bobbin car 4. If so, the P4 area picks up two empty bobbin cars 4, and the shuttle car sends the empty bobbin cars 4 to the two turntable 3 stations with the longest waiting time. Then it returns to the P4 area.

[0072] Before the double-station shuttle car 1 arrives at the P4, the system judges whether there is one station in the P1 area that needs the empty bobbin car 4 and there is a turntable station that needs to deliver the yarn package car 5 after this station (in the forward direction of the double-station shuttle car 1). Then the double-station shuttle car 1 picks up two empty bobbin cars 4 at the P4, first sends the empty bobbin car 4 at the front station to the station that needs the empty bobbin car 4, and then goes to the turntable station that needs to deliver the yarn package car 5 to complete the docking process between the turntable 3 and the double-station shuttle car 1 in the scheduling method 1.

[0073] As Figure 10 shown, the logistics scheduling process of the double-station shuttle car transportation system in the fiberglass manufacturing wire drawing area is as follows:

[0074] S100. Judge whether there are two empty stations for the empty bobbin cars;

[0075] S200. If not, continue to judge whether there is one empty station for the empty bobbin car and one station for the outgoing yarn package car, and the empty station for the empty bobbin car is in the front;

[0076] S300. If not, transfer the empty bobbin car 4 from the material inlet of the ring track 6 at the P4 to the rear station of the double-station shuttle car 1;

[0077] The S400, the double-station shuttle car 1 travels to the yarn cake car station at the yarn discharging and winding area p1, and the rotary table 3 transfers the yarn cake car 5 to the front station of the double-station shuttle car 1 to complete loading;

[0078] S500, the rear station of the double-station shuttle car 1 aligns with the just-vacated station, and transfers the empty bobbin car 4 to the empty station to complete unloading;

[0079] S600, determine whether there is a yarn cake car station in front of the double-station shuttle car 1;

[0080] S700, if not, the double-station shuttle car 1 returns to the material outbound port;

[0081] Among them:

[0082] If the judgment result of S100 is yes, then:

[0083] S101, the double-station shuttle car picks up two empty bobbin cars from the material inbound port and transports them to the empty stations of the two empty bobbin cars; then jumps to step S600;

[0084] If the judgment result of S200 is yes, then:

[0085] S201, the double-station shuttle car picks up two empty bobbin cars and transports the empty bobbin car at the front station to the empty station of the empty bobbin car; then jumps to step S400;

[0086] If the judgment result of S600 is yes, then:

[0087] S601, the double-station shuttle car picks up the yarn cake car and returns to the material outbound port p3;

[0088] Thus, a logistics transfer cycle of the double-station shuttle car 1 is completed.

[0089] Adopting the scheduling method of the present invention improves the conveying efficiency of the logistics system in the drawing area, and realizes the expansion of the single-line production capacity of glass fiber.
