[0024] Stackers are widely used in modern logistics and warehousing systems. Their main function is to automatically store and retrieve goods, and improve the utilization rate and operating efficiency of warehouses. For example, in automated warehouses, stackers are used to automatically store and retrieve goods, and can be used in conjunction with automated conveying systems and intelligent warehouse management systems (WMS) to achieve efficient management and operation of goods. In this way, the utilization rate of warehouse space can be improved, labor costs can be saved, and the speed and accuracy of goods storage and retrieval can be improved, and the error rate can be reduced. For another example, in manufacturing warehouses, stackers are used to manage large quantities of material storage and to meet the needs of production lines to provide raw materials and semi-finished products in a timely manner. In this way, on-demand production can be supported, production efficiency can be improved, and automated management of materials can be achieved to reduce inventory costs. For another example, in the electronics manufacturing industry, stackers are used to manage the storage and sorting of small, high-value components to achieve high-precision and high-security storage and retrieval operations. In this way, the accuracy and safety of warehouse management can be improved, material damage can be prevented, and a fast production rhythm can be supported to meet market demand. In addition, stackers can also be used in cold chain warehouses, retail distribution centers, automobile manufacturing, ports and docks. It can be seen that in various warehousing and logistics scenarios, stackers achieve efficient cargo storage and management through automation technology, significantly improve work efficiency and warehouse utilization, and reduce labor costs and error rates. In modern logistics and manufacturing, the application of stackers is becoming more and more extensive and important.
[0025] When working, stackers generally rely on busbars for power supply rather than self-contained batteries. First, busbars can provide a continuous and stable power supply, allowing the stacker to work uninterruptedly throughout the operation. Self-contained batteries may involve the process of regular charging or replacement of batteries, which can easily lead to downtime and affect work efficiency. Secondly, stackers have high power requirements so that they can drive their motors and other equipment, especially when working under high loads. Busbar power supply can easily meet this high power demand, while self-contained batteries may not provide enough energy or need to be replaced and charged frequently. In addition, the system maintenance using busbar power supply is relatively simple, which can reduce maintenance workload and cost compared to the scenario with self-contained batteries. In short, busbar power supply can provide continuous and stable power supply, meet high power requirements, reduce maintenance work, extend equipment life and reduce overall costs, which is better than self-contained batteries during the use of stackers.
[0026] In the prior art, when the stacker and the busbar are combined, carbon brushes are generally used as conductive devices to transmit electrical energy to the stacker through the collector arm. However, the stacker is powered by the carbon brushes on the collector arm connected to the busbar. Due to its irregular installation method, the carbon brushes are severely worn. The stacker has poor power supply contact, resulting in serious consumption of spare parts, increasing the cost of spare parts, equipment failure rate, and time-consuming manual maintenance. The daily maintenance of this power supply structure is to regularly check the wear of the stacker's carbon brushes, and replace the severely worn carbon brushes in time; and personnel regularly clean the carbon deposits of the busbar. Based on the above content, it can be seen that in the current usage scenario, when the carbon brushes are severely worn, it will cause the stacker to alarm frequently, increase the failure rate of the equipment, increase the cost of manual maintenance, and affect the operation rhythm of the production line; and because the stacker is powered by 380V, there is a risk of electric shock when cleaning carbon deposits, and the personnel will inhale a large amount of dust, which will affect their health. Based on the defects existing in the prior art, the idea of the present application is to design a power supply structure to enable close contact between the carbon brush and the busbar, thereby achieving stable power supply, thereby reducing carbon brush wear and reducing maintenance costs.
[0027] Please refer to Figure 1 , which shows an example diagram of a power supply structure provided by an embodiment of the present application. Figure 1 As shown, a power supply structure for a stacker includes: a busbar 1, a first sub-power supply structure and a second sub-power supply structure; the first sub-power supply structure and the second sub-power supply structure are electrically connected to the busbar 1 respectively, and the first sub-power supply structure and the second sub-power supply structure are located at the same height and are parallel to the busbar 1 respectively; wherein the first contact surface formed by the first sub-power supply structure and the busbar 1 is equal in area to the second contact surface formed by the second sub-power supply structure and the busbar 1. In some embodiments, the first sub-power supply structure includes a first collector arm 2 and a first carbon brush 3, the first collector arm 2 has a first mounting seat for fixing the first carbon brush 3, the first carbon brush 3 is electrically connected to the busbar to form a first contact surface; the second sub-power supply structure includes a second collector arm 4 and a second carbon brush 5, the second collector arm 4 has a second mounting seat for fixing the second carbon brush 5, the second carbon brush 5 is electrically connected to the busbar to form a second contact surface.
[0028] The first sub-power supply structure and the second sub-power supply structure are kept in parallel with the busbar, so that the first carbon brush 3 and the second carbon brush 5 are horizontally forced to contact the busbar, and any carbon brush is prevented from contacting the busbar with a single point, and the area of the first contact surface and the second contact surface are equal, so that the first carbon brush 3 and the second carbon brush 5 can be evenly stressed, and there will be no situation where the two carbon brushes are inconsistent in wear and tear, resulting in unstable power supply. Moreover, such a design can extend the service life of the carbon brushes, reduce the equipment failure rate, reduce the time spent on manual maintenance and cleaning, and improve the production efficiency of the equipment. In addition, during installation, the heights of the first sub-power supply structure and the second sub-power supply structure are consistent, and the first mounting seat and the second mounting seat are respectively designed in the first collector arm 2 and the second collector arm 4, which can make the electrical connection between the first carbon brush 3 and the second carbon brush 5 and the busbar 1 more stable, thereby achieving continuous power supply to the stacker.
[0029] Compared with the power supply structure of the prior art, the power supply structure used in this embodiment does not add any additional components, nor does it require replacement of other spare parts, which helps to reduce unnecessary waste and reduce costs; and there is no need to frequently replace carbon brushes or frequently clean carbon deposits, which can save labor resources, reduce spare parts consumption, reduce equipment failure rates, and improve production efficiency.
[0030] In some embodiments, the first collector arm 2 and the second collector arm 4 are connected in parallel.
[0031] The parallel connection of the first collector arm 2 and the second collector arm 4 can provide redundant backup. If one of the collector arms fails or has poor contact, the other collector arm can still continue to provide power, so that the stacker can continue to operate. Moreover, the parallel connection reduces the risk of single point failure and improves the reliability and stability of the entire system. In addition, the parallel connection of the first collector arm 2 and the second collector arm 4 can share the current load, reduce the current of each collector arm, reduce the heating and wear of the electrical contact points by reducing the current density, and improve the life of the collector arm; this also helps to stabilize the current supply and avoid the impact of current fluctuations on the stacker equipment. At the same time, the parallel connection of the first collector arm 2 and the second collector arm 4 can reduce the voltage drop, reduce the energy loss during power transmission, and improve the power supply efficiency; and the contact area between the first collector arm 2 and the second collector arm 4 and the busbar 1 is increased, and the contact resistance is reduced, thereby improving the efficiency and stability of power transmission.
[0032] In some embodiments, the first collector arm 2 and the second collector arm 4 are located at the same height and are parallel to the busbar 1; the first carbon brush 3 and the second carbon brush 5 are located at the same height and are parallel to the busbar 1, so that the areas of the first contact surface and the second contact surface reach the maximum value. In this way, the areas of the first contact surface and the second contact surface are increased, so that the first carbon brush 3 and the second carbon brush 5 are in full contact with the busbar 1.
[0033] In some embodiments, the first sub-power supply structure also includes a first power supply line 6, which is connected to the first collecting arm 2; the second sub-power supply structure also includes a second power supply line 7, which is connected to the second collecting arm 4; the first power supply line 6 and the second power supply line 7 respectively supply power to the stacker.
[0034] The first power supply line 6 and the second power supply line 7 are respectively bundled and connected to the first collector arm 2 and the second collector arm 4, so that the first carbon brush 3 or the second carbon brush 5 can be prevented from being seriously worn and affecting the normal use of the other carbon brush. The first power supply line 6 and the second power supply line 7 supply power together, and the stability of power supply can also be improved.
[0035] In some embodiments, the first collector arm 2 has a first spring for providing thrust to the first carbon brush 3 so that the first carbon brush 3 is in close contact with the bus bar 1; the second collector arm 4 has a second spring for providing thrust to the second carbon brush 5 so that the second carbon brush 5 is in close contact with the bus bar 1.
[0036] During installation, the force relationship between the first carbon brush 3 and the second carbon brush 5 and the bus bar 1 can be controlled by adjusting the first spring in the first collector arm 2 and the second spring in the second collector arm 4, so that the first carbon brush 3 and the second carbon brush 5 are in close contact with the bus bar 1 to avoid wear caused by uneven force.
[0037] In some embodiments, the angle between the first sub-power supply structure and the second sub-power supply structure is 180 degrees. During installation, the first sub-power supply structure and the second sub-power supply structure are pushed toward the busbar 1 by adjusting the bracket so that the angle between them is 180 degrees, and they are kept parallel to the busbar 1, so that the first sub-power supply structure and the second sub-power supply structure are in parallel contact with the busbar 1 to avoid wear caused by uneven force.
[0038] In some embodiments, the busbar 1 is arranged on the top of the stacker in a cantilever installation manner.
[0039] This design does not occupy ground space, maximizes the use of warehouse floor area, and allows for more flexible layout of warehouses and stackers to avoid interference from obstacles on the ground and sides. At the same time, the cantilever-mounted busbar is away from the ground and personnel operating area, reducing the chance of operators touching the busbar and the risk of electric shock. This design can also reduce the possibility of the busbar being damaged by dust, moisture and machinery in the ground environment. Moreover, in warehouse management, the cantilever-mounted busbar system matches the running track of the stacker, simplifying the power management and maintenance of the warehouse.
[0040] In summary, installing the busbar in a cantilever manner on the top of the stacker can significantly improve the space utilization, safety and work efficiency of the warehouse, while reducing maintenance workload and costs, optimizing the stability of power transmission, and improving the overall warehouse management level.
[0041] In some embodiments, the busbar 1 is powered by a three-phase five-wire system.
[0042] Since the stacker is under high load and long-term operation, the stability and efficiency of the power supply are required to be high. The three-phase five-wire power supply can provide continuous and balanced power transmission, reduce voltage fluctuations and current fluctuations, enable the motor and other equipment of the stacker to operate smoothly, and improve work efficiency and equipment life. Moreover, the protective grounding wire (PE) and neutral wire (N) in the three-phase five-wire system provide double protection, which can effectively reduce the probability of electric shock accidents and electrical failures. For the busbar power supply system, electrical safety is increased, the potential safety hazards that may occur during the operation of the stacker are reduced, and the safety of the working environment is improved. In addition, the stacker system may contain a variety of different types of electrical equipment, including single-phase and three-phase equipment. The three-phase five-wire power supply can flexibly support the needs of these different loads, provide a stable power supply, simplify system design and wiring, and improve the overall reliability and flexibility of the system. Therefore, the busbar in this embodiment uses a three-phase five-wire power supply, which improves the reliability, efficiency and safety of the stacker system by providing stable and efficient power transmission, enhancing system safety and supporting diversified load requirements, so that the equipment can run smoothly.
[0043] Based on similar technical concepts, the present application also provides a stacker, including a power supply structure as provided in any of the above embodiments.
[0044] The stacker in this embodiment can continue to use the original power supply structure without replacing other spare parts, which helps to reduce unnecessary waste and reduce costs; and there is no need to frequently replace carbon brushes or frequently clean carbon deposits, which can save labor resources, reduce spare parts consumption, reduce equipment failure rate, and improve production efficiency.
[0045] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments. In addition, the above embodiments can be freely combined as needed.
