Description

Technical Field

[0001] This invention relates to the field of logistics transportation technology, and in particular to a circular shuttle car with an anti-eccentricity mechanism and its control method. Background Technology

[0002] In recent years, with the rapid development of the logistics industry, circular shuttle cars have been widely used in automated warehouses and workshop logistics systems in various industries such as food, pharmaceuticals, and fiber manufacturing. With their flexibility, accuracy, and strong adaptability, they have gradually gained recognition from a wide range of users.

[0003] The circular shuttle evolved from the reciprocating shuttle. While a traditional reciprocating shuttle travels back and forth along a straight track, a circular shuttle can travel in a closed loop along a circular track. Compared to the reciprocating shuttle, the circular shuttle has a stronger conveying capacity, higher conveying efficiency, and a more compact overall layout, making it more suitable for automated logistics systems in workshop production.

[0004] In some practical applications with small turning radii, single-wheel drive is widely used in existing circular shuttle vehicles. However, this drive scheme has certain instability, especially in application scenarios where the load is misaligned, which can easily lead to rollover safety issues. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a circular shuttle with an anti-eccentric loading mechanism and its control method, which can ensure that the vehicle will not overturn under eccentric loading conditions, thereby increasing the overall safety of the vehicle.

[0006] The present invention discloses a circular shuttle car with an anti-eccentricity mechanism, which travels on a first circular track and a second circular track laid on a conveying surface. The shuttle car comprises a car body and a driving assembly connected to the car body. The driving assembly includes a drive wheel set, a driven wheel set, and an anti-eccentricity wheel set. The drive wheel set and the anti-eccentricity wheel set are located on the same side of the car body, and the anti-eccentricity wheel set is located on the side of the drive wheel set and is used to travel on the first circular track. The driven wheel set is located on the other side of the car body and is used to travel on the second circular track. The drive wheel set drives the anti-eccentricity wheel set and / or the driven wheel set to move along the first circular track respectively; and / or

[0007] The drive wheel assembly drives the anti-deviation wheel assembly and / or the driven wheel assembly to move along the second circular track.

[0008] As a further optimization of the present invention, the drive wheel assembly includes a drive member and a drive wheel driven by the drive member, the drive wheel traveling on the first annular track.

[0009] As a further optimization of the present invention, the number of drive wheels is at least one, and the at least one drive wheel is located at the middle position of the bottom of the vehicle body.

[0010] As a further optimization of the present invention, the driven wheel set includes driven wheels, and the number of driven wheels is at least two. The at least two driven wheels are located at the bottom position on the other side of the vehicle body and travel on the second circular track.

[0011] As a further optimization of the present invention, the at least two driven wheels and the at least one driving wheel form a triangle.

[0012] As a further optimization of the present invention, the anti-deviation wheel assembly includes a plurality of anti-deviation wheels, which are connected to the bottom of the vehicle body.

[0013] As a further optimization of the present invention, the number of anti-deviation wheels is at least two, and the at least two anti-deviation wheels are symmetrically arranged on the front and rear sides of the drive wheel assembly.

[0015] As a further optimization of the present invention, it also includes an anti-deviation detection component, which includes a mechanical sensor located on the rear side of the anti-deviation wheel assembly and is used to detect the off-center load of the vehicle body.

[0016] As a further optimization of the present invention, a control component is also included, which is electrically connected to the drive walking component and the anti-deviation detection component, and is used to control the working state of the drive walking component and the anti-deviation detection component.

[0017] A control method for a circular shuttle car with an anti-eccentricity mechanism, the method comprising the following steps:

[0018] Obtain the off-center load of the vehicle body;

[0019] An alarm message is issued when the off-center load exceeds the preset value;

[0020] Based on the alarm information, control the drive walking component to stop moving.

[0021] As a further optimization of the present invention, the step of providing the position of the load center of gravity is also included.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. The circular shuttle of the present invention improves the vehicle's ability to resist eccentric loads by adding anti-eccentric wheels, thereby increasing the safety of the vehicle.

[0024] 2. The circular shuttle of the present invention automatically detects the off-center load by adding mechanical sensors.

[0032] The invention will now be further described with reference to the accompanying drawings.

[0033] like Figure 1-2As shown, the present invention provides a circular shuttle with an anti-eccentricity mechanism, which travels on a first circular track 1 and a second circular track 2 laid on a conveying surface. The shuttle includes a vehicle body 3 and a drive assembly connected to the vehicle body 3. The drive assembly includes a drive wheel set 4, a driven wheel set 5, and an anti-eccentricity wheel set 6. The drive wheel set 4 and the anti-eccentricity wheel set 6 are located on the same side of the vehicle body 3, with the anti-eccentricity wheel set 6 located on the side of the drive wheel set 4 and used for traveling on the first circular track 1. The driven wheel set 5 is located on the other side of the vehicle body 3 and used for traveling on the second circular track 2. The drive wheel set 4 drives the anti-eccentricity wheel set 6 and the driven wheel set 5 to move along the first circular track 1, or the drive wheel set 4 drives the anti-eccentricity wheel set 6 and the driven wheel set 5 to move along the second circular track 2, thereby improving the vehicle's anti-eccentricity capability, increasing the vehicle's safety, achieving a dual-wheel drive effect, and reducing the vehicle's manufacturing and operating costs.

[0034] In this embodiment, the drive wheel assembly 4, the driven wheel assembly 5, and the anti-deviation wheel assembly 6 work together with the circular shuttle to ensure that the circular shuttle travels in a balanced and stable manner on the circular track.

[0035] In another embodiment of the present invention, unlike the embodiments described above, the drive wheel assembly 4 in this embodiment includes a drive member and a drive wheel driven by the drive member, the drive wheel traveling on the first annular track 1. The drive member is, for example, a drive motor, which provides power to the drive wheel, enabling it to travel on the first annular track, thereby transporting the vehicle body and its components along the first annular track.

[0036] To reduce the manufacturing and operating costs of the circular shuttle, this embodiment uses only one drive wheel, located at the bottom center of the vehicle body 3. This further reduces the turning radius of the vehicle, improves its maneuverability, and makes the overall design more compact.

[0037] As another embodiment of the present invention, unlike the above embodiments, the driven wheel set 5 in this embodiment includes driven wheels, and the number of driven wheels is at least two. The at least two driven wheels are located at the bottom position on the other side of the vehicle body and travel on the second circular track to provide support for the load of the entire vehicle.

[0038] In another embodiment of the present invention, unlike the above embodiments, the at least two driven wheels and the at least one driving wheel in this embodiment form a triangle with each other. This allows the vehicle body to be driven by a single wheel, effectively reducing the production cost of the vehicle body.

[0039] In this embodiment, during actual operation, two driven wheels and one drive wheel directly act on the track to provide support for the entire vehicle. The drive wheel, while providing support, primarily provides the driving force for the entire vehicle to complete its normal working tasks. To ensure that the vehicle body does not tip over under eccentric loading, this embodiment includes an anti-eccentricity wheel assembly 6. This assembly 6 comprises multiple anti-eccentricity wheels connected to the bottom of the vehicle body 3. This improves the vehicle's resistance to eccentric loading and increases its overall safety.

[0040] In another embodiment of the present invention, unlike the above embodiments, the number of anti-deviation wheels in this embodiment is at least two, and the at least two anti-deviation wheels are symmetrically arranged on the front and rear sides of the drive wheel set 4. Therefore, when the circular shuttle car is running and makes a turning motion, due to the instability of single-wheel drive on one side, the car may tip over. At this time, the anti-deviation wheels contacting the track will provide support.

[0041] Meanwhile, the anti-deviation wheel set in this embodiment can raise the entire drive side of the circular shuttle car by adding a sloping pad under the anti-deviation wheel when the drive wheel of the trolley malfunctions and needs to be repaired, making it convenient for manual disassembly of the drive wheel.

[0042] In another embodiment of the present invention, unlike the embodiments described above, the anti-deviation wheel in this embodiment is made of nylon material. Therefore, this nylon design has a shock-absorbing effect, reducing noise while further reducing the impact force on the track, eliminating the instantaneous impact load on the track, and providing a certain degree of protection for the track itself.

[0043] In another embodiment of the present invention, unlike the above embodiments, the circular shuttle in this embodiment further includes an anti-deviation detection component 7. The anti-deviation detection component 7 includes a mechanical sensor located behind the anti-deviation wheel assembly 6, used to detect the off-center load of the vehicle body. Therefore, when the off-center load of the vehicle exceeds a certain value, it exceeds the normal operating capacity of the vehicle. The mechanical sensors on the two anti-deviation wheels contact the track, triggering a safety alarm. The alarm signal is transmitted to the control terminal, which then issues a stop alarm and displays the alarm information on the central control terminal, guiding workers to adjust the load center of gravity. However, the mechanical sensor in this application is not limited to this; it can also detect obstacles in advance.

[0044] Because the trolley travels at high speeds, there is a risk that the load may fall off the track. If objects on the track are not cleared in time, there is a significant risk of derailment when the trolley passes at high speed. By installing mechanical sensors, obstacles can be detected in advance, allowing the trolley a safe deceleration distance and preventing derailment.

[0045] In another embodiment of the present invention, unlike the above embodiments, the circular shuttle in this embodiment further includes a control component. This control component is electrically connected to the drive and travel component and the anti-deviation detection component 7, and is used to control the working state of the drive and travel component and the anti-deviation detection component. Therefore, when the circular shuttle is running and makes a turning motion, due to the instability of single-wheel drive on one side, the shuttle may overturn. At this time, the anti-deviation wheel contacting the track will also provide support, and the mechanical sensor will issue an alarm. The control component in this embodiment, such as the controller, will control the shuttle to slow down or stop according to the degree of overturning, and send an alarm message to the central control unit, awaiting staff intervention. This achieves intelligent control of the circular shuttle, facilitating staff management and reducing their workload.

[0046] like Figure 3 As shown, a control method for a circular shuttle car with an anti-eccentricity mechanism includes the following steps:

[0047] S1. Obtain the off-center load of the vehicle body;

[0048] S2. When the off-center load exceeds the preset value, an alarm message is issued;

[0049] S3. Based on the alarm information, control the driving walking component to stop moving.

[0050] In practical operation, a circular shuttle car typically consists of two driven wheels and one driving wheel that act directly on the track to provide support for the entire vehicle. The driving wheel provides support while primarily driving the entire vehicle to complete its normal work tasks. When the load is evenly distributed across the entire vehicle, the car runs smoothly.

[0051] When the load is uneven, the trolley is at risk of tipping over. When the tipping exceeds a certain amount, the anti-eccentric wheels on the trolley come into contact with the track, thus providing a certain degree of support and improving the stability of the entire vehicle.

[0052] As the trolley continues to tip over, it exceeds its normal operating capacity. The mechanical sensors on the two anti-deviation wheels come into contact with the track, triggering a safety alarm. The alarm signal is then transmitted to the control terminal, which issues a stop alarm.

[0053] To facilitate quick handling of anomalies by staff, as another embodiment of the present invention, unlike the above embodiments, the control method in this embodiment further includes a step of providing the load center of gravity position, thereby helping staff to quickly adjust the load center of gravity. That is, the control terminal displays alarm information at the central control terminal, guiding workers to adjust the load center of gravity.

[0054] In summary, this invention employs a single-sided, single-wheel drive system combined with anti-roll wheels and mechanical sensors, which improves the stability of the vehicle and reduces its manufacturing and operating costs. Because the drive wheels are centrally positioned, the turning radius is further reduced, improving maneuverability and resulting in a more compact overall design.
