Description

Technical Field

[0001] This utility model relates to the technical field of turnout changing devices, and is a ring-crossing energy-saving dispatching device under non-continuous crossing conditions. Background Technology

[0002] In the field of circular shuttle equipment scheduling technology within automated logistics conveying systems, a single circular shuttle needs to perform both inbound and outbound functions. However, these two operations are not continuous, or only one operation is continuous. Excess circular shuttles experience empty runs, which not only affects overall efficiency but also wastes energy.

[0003] Chinese patent application CN114772119B discloses a track-changing device for a circular shuttle track, a shuttle track, and a logistics conveying system. The track-changing device for the circular shuttle track includes at least one straight track, including a horizontally arranged main track, with an arc-shaped secondary track on one side of the main track, and the centerline of the secondary track and the centerline of the main track forming an angle; at least one translation track, perpendicular to the straight track, including a power source, a second combined support, and a movable track, the movable track and the second combined support being slidably connected, the power source driving the movable track to move along the second combined support; at least one arc track, one side of which is connected to the translation track; at least one rotary mechanism, the rotary mechanism being linked to the movable track; when the rotary mechanism rotates to a first position, the rotary mechanism connects the straight track and the translation track, and the movable track is connected to the straight track; when the rotary mechanism rotates to a second position, the rotary mechanism connects the translation track and the arc track. This patent is used to optimize the track route of a circular shuttle, avoiding the circular shuttle's entire loop travel path when the transport volume is small. It optimizes the system scheduling scheme of the circular shuttle, enabling the circular shuttle, which runs on a fixed route, to optimize the route according to actual needs, making the circular shuttle scheduling scheme more flexible.

[0004] The above-mentioned optimization of the overall route scheduling for the circular shuttle is achieved by using the circular shuttle track-changing device to alter the overall logistics transport route, thereby shortening the empty loop distance for short-distance transport. This track-changing device allows for flexible route changes simultaneously for both long-distance and short-distance logistics transport.

[0005] By using this track-changing scheme, the number of shuttle cars on the overall loop remains unchanged, which leads to an improvement in the overall conveying system's handling efficiency. Generally, when the system's total conveying efficiency is fixed, the efficiency of each loop is directly proportional to the loop length; that is, the conveying efficiency decreases as the loop length shortens.

[0006] The aforementioned track-changing scheme only alters the track route of the circular shuttle without changing the number of circular shuttles on track. This may result in excessive surplus in the circular shuttle system's transport efficiency or an excessively high density of circular shuttles on track, which could negatively impact the overall system scheduling. Furthermore, the above adjustment scheme is not well-suited for transport scenarios where the system's transport efficiency varies significantly.

[0007] If the number of shuttle cars is adjusted by directly using lifting equipment to remove or add shuttle cars, the work is cumbersome and may damage the precision structure of the circular shuttle car. Therefore, other methods are considered to adjust the number of circular shuttle cars on track. Summary of the Invention

[0008] This invention provides a ring-crossing energy-saving scheduling device under non-continuous cross-operation conditions, which overcomes the shortcomings of the prior art. It can effectively solve the problem that the number of existing on-orbit ring shuttles is mismatched with the handling efficiency, resulting in excessive surplus handling efficiency, empty ring shuttles running and wasting energy, and affecting the overall efficiency.

Detailed Implementation

[0024] This utility model is not limited to the following embodiments, and the specific implementation method can be determined according to the technical solution of this utility model and the actual situation.

[0025] In this utility model, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as front, back, top, bottom, left, right, etc. The positional relationships are determined based on the layout direction of the attached diagram in the instruction manual.

[0026] The present invention will be further described below with reference to the embodiments and accompanying drawings: Example 1: As shown in the attached document Figure 1-6 As shown, the loop-through energy-saving dispatching device under non-continuous crossing conditions includes a main line 1 and a temporary line 2. The main line 1 and the temporary line 2 are connected at both ends by a turnout rail-changing device. The turnout rail-changing devices at both ends have the same structure and are symmetrically distributed from left to right. The turnout rail-changing device located on the left includes a translational conversion component and a rotating component that can be docked together. The translational conversion component includes a first power mechanism, a fixed frame 3, a moving frame 4, a horizontal track 5, and an arc track 6. The moving frame 4 is slidably connected to the upper side of the fixed frame 3. The horizontal track 5 and the arc track 6 are provided on the upper side of the moving frame 4. The front part of the moving frame 4 is fixedly connected to the first power mechanism. The first power mechanism can pull the moving frame 4 to move back and forth so that the horizontal track 5 docks with the main line 1 or the arc track 6 docks with the rotating component.

[0027] When a change in flow rate is input into the logistics transportation system, the task scheduling control system calculates the real-time handling capacity as the transport flow rate increases or decreases. It then sends out the scheduling command, assigning or temporarily storing surplus or needed circular shuttle cars. The switchgear device on the left activates, controlling the first power mechanism to push the moving frame 4 backward, aligning the arc track 6 with the main line 1. The rotating component moves to the alignment position on the arc track 6. After the circular shuttle car reaches the fixed frame 3, it enters the temporary storage line 2 along the arc track 6 and the rotating component for temporary storage and rest. When the resting circular shuttle car... Once the required number of vehicles is reached, the switch changeover device is reset, and the online vehicles continue to travel along the main line 1. When the flow of the logistics system exceeds the handling capacity of the on-rail vehicles, the dispatch control system dispatches vehicles in the buffer zone, causing the switch changeover device on the right to activate in the same manner as the switch changeover device on the left. This connects the exit end of the temporary storage line 2 to the main line 1, and the circular shuttle car enters the main line 1 from the temporary storage line 2 via the switch changeover device on the right. The entry and exit from the temporary storage line 2 follows the first-in-first-out principle, and the number of circular shuttle cars is dynamically adjusted. Under the premise of ensuring that the flow of the transportation system meets the demand, shuttle car resources are rationally allocated to avoid resource waste.

[0028] The dispatch control system monitors the operating status and task frequency of each shuttle in real time, dynamically adjusting the vehicle handover sequence based on historical data and real-time traffic analysis. For vehicles frequently performing tasks, they are prioritized for task waiting in the buffer zone, provided the system's traffic demand is met. This intelligent dispatch mechanism balances the load on each vehicle, keeping the workload within a reasonable range, preventing excessive wear and tear, and extending equipment lifespan. Alternating task delivery ensures the continuity and stability of task execution, further improving the overall lifespan of the logistics delivery system and preventing inconsistent wear and tear due to varying task loads. Furthermore, the dispatch control system optimizes vehicle maintenance cycles based on real-time data and historical records, ensuring each shuttle operates in optimal condition, further reducing maintenance costs and improving the long-term reliability and economy of the system.

[0029] The above-mentioned energy-saving scheduling device under non-continuous cross-operation conditions can be further optimized and / or improved according to actual needs: Example 2: As shown in the attached document Figure 2 , 3As shown, the first power mechanism includes a first motor 23, a gear 7, and a rack 8. The first motor 23 is mounted outside the fixed frame 3, and the gear 7 is driven to the output end of the first motor 23. The rack 8, which meshes with the gear 7, is mounted on the movable frame 4. The first motor 23 drives the gear 7 to rotate, and the gear 7 meshes with the rack 8, thereby pulling the rack 8 to move back and forth, thus adjusting the position of the horizontal track 5 or the arc track 6 so that it connects with the main line 1 or the temporary storage line 2.

[0030] Example 3: As shown in the attached document Figure 2-6 As shown, the rotating assembly includes a fixed track, a rotating mechanism, and a second power mechanism. The fixed track includes two parallel front guide rails 9 and a rear guide rail 10. The left ends of the front guide rails 9 and the rear guide rail 10 can connect with the arc-shaped track 6, and the right ends of the front guide rails 9 and the rear guide rail 10 connect with the temporary storage line 2. The rear guide rail 10 and the main line 1 are provided with notches at their intersections, and a rotating mechanism is installed at the notches. The rotating mechanism includes a mounting frame 11, a plate 12, and a connecting track 13. The mounting frame 11 contains a nylon block 14 and a support seat 15. The mounting frame 11 below the plate 12 contains a support seat 15, and a nylon block 14 is installed on the upper side of the support seat 15. The connecting track 13 is installed on the plate 12. The second power mechanism is installed on the outside of the mounting frame 11 and is connected to the plate 12. The second power mechanism can pull the plate 12 to rotate so that the connecting track 13 connects with the rear guide rail 10 or with the main line 1.

[0031] In the initial state, the connecting track 13 is horizontally connected to the main line 1. When the circular shuttle needs to enter from the main line 1, the second power mechanism rotates the plate 12, causing the connecting track 13 to rotate at a certain angle and connect with the rear guide rail 10. The first and second power mechanisms act simultaneously, causing the arc-shaped guide rail to connect with the connecting track 13, and smoothly enter the temporary storage line 2. The nylon block 14 and the support seat 15 provide support for the plate 12. The friction between the nylon block 14 and the plate 12 is small and does not affect the rotation of the plate 12.

[0032] Example 4: As shown in the appendix Figure 2-6 As shown, the second power mechanism includes a second motor 16 and a swing arm 17. The output end of the second motor 16 is connected to the swing arm 17, and the other end of the swing arm 17 is hinged to the lower side of the plate 12. The rotation of the output end of the second motor 16 drives the swing arm 17 to rotate, which in turn pulls the plate 12 to rotate, thereby adjusting the position of the connecting track 13.

[0033] Example 5: As shown in the attached document Figure 2-6As shown, the rotating assembly also includes a slewing bearing 18. A slewing bearing 18 is located on the lower side of the middle portion of the plate 12. The inner ring of the slewing bearing 18 is higher than the outer ring. The upper side of the inner ring of the slewing bearing 18 is fixedly installed together with the plate 12, and the outer ring of the slewing bearing 18 is mounted on a bearing housing. By setting the slewing bearing 18, the middle portion of the plate 12 can be supported, and the plate 12 can rotate smoothly.

[0034] Example 6: As attached Figure 2 , 3 As shown, two first proximity switches 19 are installed at intervals at the rear of the fixed frame 3, and a first sensing baffle 20 is installed on the upper rear side of the movable frame 4. The first proximity switches 19 are connected to the control unit, which is connected to the first power mechanism. The first power mechanism pushes the movable frame 4 to move backward. When the first sensing baffle 20 approaches the first proximity switch 19 located at the rear, the control unit controls the first power mechanism to stop moving. At this time, the arc-shaped track 6 is connected to the main line 1, that is, the main line 1 is connected to the temporary storage line 2. When it is necessary to connect the main line 1, the first power mechanism pulls the movable frame 4 to move forward. When the first sensing baffle 20 approaches the first proximity switch 19 located at the front, the control unit controls the first power mechanism to stop moving. The horizontal track 5 is connected to the main line 1, and the main line 1 is a pass. By setting the first proximity switches 19 to control the position of the movable frame 4, the horizontal track 5 and the arc-shaped track 6 are positioned. As needed, the control unit adopts existing known technology, such as a PLC.

[0035] Example 7: As attached Figure 2-6 As shown, the mounting frame 11 is provided with two second proximity switches 21 facing different directions, and two second sensing baffles 22 are installed at intervals on the plate 12. The second proximity switches 21 are connected to the control unit, and the control unit is connected to the second power mechanism.

[0036] When the plate 12 is horizontal, the two second sensing baffles 22 are spaced apart. The first second proximity switch 21 is located on the left second sensing baffle 22, and the second second proximity switch 21 is located between the two second sensing baffles 22. When the temporary storage route needs to be connected, the second power mechanism activates, rotating the plate 12. When the right second sensing baffle 22 approaches the second proximity switch 21, the control unit controls the second power mechanism to stop. At this time, the plate 12 rotates to its final position, and the connecting rail 13 aligns with the rear guide rail 10. When the main line 1 needs to be connected, the second power mechanism activates, rotating the plate 12 back to its original position. When the left second sensing baffle 22 approaches the first proximity switch 19, the control unit controls the second power mechanism to stop. The connecting rail 13 rotates to a horizontal position, aligning with the main line 1. The second proximity switch 21 controls the position of the connecting rail 13, ensuring accurate alignment with the rear guide rail 10, allowing the circular shuttle to smoothly enter the temporary storage route 2. The control unit may employ existing known technologies, such as a PLC, as needed.

[0037] The above technical features constitute various embodiments of this utility model, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
