Description

Technical Field

[0001] This utility model specifically relates to the field of track changing technology, and more specifically to an automatic track changing system for an RGV shuttle. Background Technology

[0002] RGV (Rail Guided Vehicle) is a rail-guided vehicle, also known as a rail shuttle.

[0003] RGVs typically employ a combination of straight and curved tracks, as well as circular tracks. Straight tracks are used for regular straight-line travel, curved tracks enable directional changes, and circular tracks can construct loop transport routes. The strategic combination of different tracks allows RGVs to choose from a variety of paths. For example, in a logistics warehouse, RGVs rapidly transport goods on straight tracks, and when they encounter a sorting area, they use curved tracks to enter different sorting channels.

[0004] Traditional track-changing devices typically come in two types: one is a horizontal sliding track-changing mechanism; the other has two tracks on a turntable, which can be rotated to change tracks. Horizontal sliding track-changing devices require a large lateral space, and RGV shuttles also have lateral space requirements when transporting goods. If the horizontal sliding track-changing device is too high, it will prevent the RGV shuttle from moving normally. Turntable rotation track-changing mechanisms require both curved and straight tracks to be fixed on the turntable at the same time, which makes the installation and replacement of the two tracks difficult, and maintenance difficult. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic track-changing device for an RGV shuttle, which achieves the transformation between curved and straight tracks by flipping. The drive device is located at the bottom of the track, which can prevent the RGV shuttle from being affected and avoid the interlacing installation of curved and straight tracks, thereby improving the quick disassembly, repair and maintenance of the track; thus solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic track-changing device for an RGV shuttle includes a mounting plate with two parallel conveying rails and a return rail, wherein one end of the return rail is connected to an arc-shaped rail.

[0008] A flipping mechanism is provided between the conveying guide rail and the arc-shaped guide rail; the flipping mechanism includes a speed reducer unit for flipping the arc-shaped guide rail and the lower flipping plate; an arc-shaped guide rail is installed on the flipping plate, and a linear guide rail is installed on the lower flipping plate;

[0009] The mounting plate has a floor on its outer side; the floor has a linear guide rail; the linear guide rail and the conveying guide rail are on the same straight line.

[0010] As a further technical solution of this utility model, the bottom sides of the conveying guide rail, return guide rail, arc guide rail, linear guide rail, arc-shaped variable rail and linear variable rail are all fixed by the rail pressure plate.

[0011] As a further technical solution of this utility model, the speed reducer unit is fixed on the speed reducer base, which is fixed on one side of the mounting bracket; there are two mounting brackets, and the two mounting brackets are fixed on the base.

[0012] A flipping frame is rotatably connected between the two mounting brackets via a pivot; the upper end of the flipping frame is fixed with an upper flipping plate via a support base, and the lower end is fixed with a lower flipping plate.

[0013] As a further technical solution of this utility model, the arc-shaped variable rail on the upper flip plate and the linear variable rail on the lower flip plate can both be connected to the conveying guide rail and the arc-shaped guide rail or the linear guide rail after flipping 180 degrees.

[0014] As a further technical solution of this utility model, the bottom of the mounting plate is fixed on the support frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, after receiving goods, the RGV shuttle moves and transports along the conveyor rail. After the track is changed by the flipping mechanism, it enters the arc-shaped rail and then enters the return rail, realizing an arc-shaped track change for the purpose of transporting goods; or after the track is changed by the flipping mechanism, it enters the straight rail for the purpose of transporting goods.

[0017] 2. In this utility model, when the reducer base is working, the rotating shaft can drive the tilting frame to rotate. When the tilting frame drives the upper tilting plate and the lower tilting plate to rotate, it can realize the change of arc track and straight track, thereby realizing the track changing function in the RGV shuttle car transmission process.

[0018] 3. In this utility model, the distance between the upper tilting plate and the axis of the shaft connected to the reducer unit is the same as the distance between the lower tilting plate and the axis of the shaft connected to the reducer unit; thus, when the upper or lower tilting plate is tilted, it can be accurately aligned with the mounting plate, and ensure that the conveying guide rail and the arc guide rail or linear guide rail are connected.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-7 In this embodiment of the utility model, an automatic track changing system for an RGV shuttle includes a mounting plate 1, on which two parallel conveying guide rails 2 and a return guide rail 3 are provided, wherein one end of the return guide rail 3 is connected to an arc-shaped guide rail 4.

[0030] A flipping mechanism 5 is provided between the conveying guide rail 2 and the arc-shaped guide rail 4; the flipping mechanism 5 includes a reducer unit 50 for flipping the arc-shaped variable rail 56 and the lower flipping plate 57; the arc-shaped variable rail 56 is installed on the flipping plate 55, and the linear variable rail 58 is installed on the lower flipping plate 57.

[0031] The mounting plate 1 has a floor 8 on its outer side; the floor 8 has a linear guide rail 7; the linear guide rail 7 and the conveying guide rail 2 are on the same straight line.

[0032] As a further explanation of this embodiment, the RGV shuttle can employ either single-track or double-track transmission, depending on the actual application scenario and requirements. This embodiment is used for logistics transportation, therefore single-track transmission is employed. A single track supports the RGV vehicle's operation, resulting in a relatively simple structure, lower cost, smaller footprint, and smaller turning radius. The single-track RGV can be programmed to perform tasks such as picking up, transporting, and placing goods, and can communicate with a host computer or WMS system. Combined with RFID, barcode, and other identification technologies, it can achieve automated identification and storage functions, offering advantages such as high speed, high flexibility, and the ability for multiple vehicles to work in coordination.

[0033] By adopting the above technical solution, the RGV shuttle (not shown in the figure) moves and transmits along the conveyor rail 2 after receiving the goods. After the track change by the flipping mechanism 5, it enters the arc-shaped rail 4 and then enters the return rail 3, realizing an arc-shaped track change in order to transfer the goods.

[0034] Alternatively, after changing track using the flipping mechanism 5, it will enter the linear guide rail 7 for cargo transfer.

[0035] In this embodiment, the bottom sides of the conveying guide rail 2, return guide rail 3, arc guide rail 4, linear guide rail 7, arc variable rail 56 and linear variable rail 58 are all fixed by the track pressure plate 6.

[0036] Multiple tracks are fixed by setting track pressure plates 6, which is simple in structure and easy to install.

[0037] In this embodiment, the speed reducer unit 50 is fixed to the speed reducer base 59, which is fixed to one side of the mounting bracket 52; there are two mounting brackets 52, and the two mounting brackets 52 are fixed to the base 51.

[0038] A flipping frame 53 is rotatably connected between two mounting brackets 52 via a pivot; the upper end of the flipping frame 53 is fixed with an upper flipping plate 55 via a support base 54, and the lower end is fixed with a lower flipping plate 57.

[0039] By adopting the above technical solution, when the reducer base 59 is working, the rotating shaft can drive the tilting frame 53 to rotate. When the tilting frame 53 drives the upper tilting plate 55 and the lower tilting plate 57 to rotate 180 degrees, the change of arc-shaped track 56 and straight track 58 can be realized, thereby realizing the track changing function in the RGV shuttle car transmission process.

[0040] In this embodiment, the arc-shaped variable rail 56 on the upper flip plate 55 and the linear variable rail 58 on the lower flip plate 57 can both dock with the conveying guide rail 2 and the arc-shaped guide rail 4 or the linear guide rail 7 after flipping 180 degrees.

[0041] More specifically, the distance between the upper tilting plate 55 and the axis of the shaft connected to the reducer unit 50 is the same as the distance between the lower tilting plate 57 and the axis of the shaft connected to the reducer unit 50; in this way, when the upper tilting plate 55 or the lower tilting plate 57 is rotated 180 degrees, it can be accurately aligned with the mounting plate 1, and ensure that the conveying guide rail 2 and the arc guide rail 4 or the linear guide rail 7 are connected.

[0042] In this embodiment, the bottom of the mounting plate 1 is fixed on the support frame 9.

[0043] It should be noted that a gap is reserved between the mounting plate 1 and the upper flip plate 55 or the lower flip plate 57 so that the upper flip plate 55 or the lower flip plate 57 can be flipped normally.

[0044] By adopting the above technical solutions, either elevated installation or pre-embedded installation can be used; the scope of application is wide.

[0045] As a further explanation of the above embodiments, the track changing mechanism can be based on different loaded goods. For example, it can be electrically connected to the central control equipment through vision sensors, CCD cameras, etc.; it can determine where to be transported based on the different goods being transported; and then the central control equipment (which can be, but is not limited to, a central processor, PLC controller, or industrial computer) issues instructions to control the reducer unit 50 to operate, thereby realizing the track changing function.

[0046] Alternatively, proximity switches can be used for control. This method involves adding sensors to the logistics vehicles, with different sensor locations for different goods. For example, if the logistics system has two transmission lines, a sensor is installed on the left side of the logistics vehicle carrying goods A, and the corresponding proximity switch is located on the left side of the conveyor rail 2. A sensor is installed on the right side of the logistics vehicle carrying goods B, and the corresponding proximity switch is located on the right side of the conveyor rail 2. The feedback signal from different proximity switches determines which rail to connect to. In addition, the proximity switches are electrically connected to the central control unit to control the operation of the speed reducer unit 50.

[0047] Alternatively, the central control equipment of the cargo sorting system can directly control the reducer unit 50 via signal lines to control the track change requirements according to the order of the dispatched goods.

[0048] The specific examples mentioned above can be designed according to actual needs; and the above implementation methods are all existing technologies, and their specific control principles will not be elaborated here.

[0049] The working principle of this utility model is as follows: After receiving the goods, the RGV shuttle moves and transmits along the conveying guide rail 2. After the track change by the flipping mechanism 5, it enters the arc-shaped guide rail 4 and then enters the return guide rail 3, realizing an arc-shaped track change in order to transfer the goods.

[0050] Alternatively, after changing track using the flipping mechanism 5, it will enter the linear guide rail 7 for cargo transfer;

[0051] When the reducer base 59 is working, the rotating shaft can drive the tilting frame 53 to rotate. When the tilting frame 53 drives the upper tilting plate 55 and the lower tilting plate 57 to rotate 180 degrees, it can realize the change of arc track 56 and straight track 58, thereby realizing the track changing function in the RGV shuttle car transmission process.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0053] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
