[0008] In some embodiments, a set of loading device is shared between every two storage bins.

[0009] In some embodiments, the storage system also includes at least one of the following: an electric hoist, which lifts the ton bag containing raw materials onto the unpacking machine; a loading dust collector, which collects the dust generated during the loading process and sends it into the bucket elevator to avoid waste; and a bucket elevator outlet dust collector, which collects the dust generated during the discharging process to prevent dust from overflowing.

[0010] In some embodiments, the discharging device includes: an activation hopper, arranged at the lower part of the storage bin, used to generate vibration when discharging downward to prevent the raw materials from clogging the pipeline; a second quantitative material distribution valve, arranged at the lower part of the activation hopper, used to control the discharging speed; a third conveyor, which transports the raw materials in the storage bin to the conveying device; a second valve, which is used to adjust the opening so that the storage bin can be switched to connect to different third conveyors.

[0028] Example

[0029] Figure 1 is a schematic diagram of the structure of a photovoltaic glass raw material storage system provided by an embodiment of the present disclosure, such as Figure 1As shown, the storage system includes: a storage bin for storing raw materials of photovoltaic glass; a loading device for conveying the raw materials into the storage bin; a discharging device for conveying the raw materials in the storage bin to the conveying device; and a conveying device for conveying the raw materials in the discharging device to the production workshop.

[0030] Specifically, after the photovoltaic glass raw materials enter the factory, the loading device is used to transport the raw materials directly to the storage bin for storage. Using the storage bin to store the raw materials can not only reduce the occupied warehouse area but also facilitate the control of the ambient temperature and humidity in the storage bin, so that the raw materials can be better stored. The raw materials in the storage bin are transported by the discharge device and transported to the conveying device, and then the conveying device is used to transport the raw materials to the production workshop, completing the transportation of the raw materials. The coordinated use of the loading device, the discharge device and the conveying device solves the problem of using manpower for secondary transportation of stored raw materials, and improves the efficiency of storage and transportation of photovoltaic glass raw materials.

[0031] In some embodiments, there are at least two storage bins, and the storage bins serve as backup for each other.

[0032] Specifically, the storage bin can be designed as a container with a relatively high height and a relatively small area. Through such a design, when a certain amount of raw materials are loaded, the storage bin occupies a smaller area. The number of storage bins 15 can be adjusted accordingly according to factors such as actual storage demand and warehouse size, but there are at least two, and each of them is used as a backup. By using the storage bins as a backup, it is possible to avoid the situation where the production line is affected by waiting for raw materials when one of the storage bins is abnormal or undergoing maintenance, thereby ensuring the continuity of raw material supply.

[0033] Figure 2 Schematic diagram of a specific implementation of the photovoltaic glass raw material storage system disclosed in the embodiment of the present disclosure. Figure 2 As shown, the feeding device includes: a bag unpacker 3, used to unpack the ton bag 2 containing raw materials; a first quantitative material distribution valve 16, used to control the speed of the raw materials being input into the conveyor; a bucket elevator 1, used to lift the raw materials to the upper part of the storage bin 15; a first conveyor 4, used to convey the raw materials in the bag unpacker 3 to the entrance of the bucket elevator 1; a first valve 7, used to adjust the opening so that the bucket elevator 1 can be switched to connect to different storage bins 15 discharge channels; a second conveyor 8, placed between the bucket elevator 1 and the storage bin 15, discharges the raw materials from the bucket elevator 1 into the storage bin 15.

[0034] Specifically, during the loading process, after the bag unpacker is used to unpack the ton bag 2 containing the raw materials, the raw materials pass through the first quantitative material distribution valve 16, and the speed of conveying the raw materials to the conveyor is controlled according to production requirements. The raw materials are conveyed to the entrance of the bucket elevator 1 through the first conveyor 4, and the bucket elevator 1 lifts the raw materials to the upper part of the storage bin 15. The raw materials are conveyed to the discharge channels of different storage bins 15 through the first valve 7, and the raw materials are conveyed to the corresponding storage bins 15 through the second conveyor 8.

[0035] It is understandable that technicians in this field can replace or remove the unpacking machine 3 in the embodiment of the present disclosure according to the types and forms of raw materials stored and transported in actual applications. The quantitative dispensing valve controls the speed of discharging materials to achieve stable control of the feed flow rate, avoid production problems caused by flow fluctuations, and improve the stability and efficiency of the production process. The bucket elevator 1 used in the embodiment of the present disclosure is used to lift the raw materials to the upper part of the storage bin 15. Technicians in this field can replace the bucket elevator 1 with other equipment with the same function according to the actual transport items. The conveyor used in the embodiment of the present disclosure is a belt conveyor. By the same token, it can be replaced by other equipment that can achieve the same function, such as a chain conveyor, a pipeline conveying system, etc. The valve can be a three-way valve, a four-way valve, etc. with an adjustable opening to switch different connections.

[0036] In some embodiments, every two storage bins 15 share a set of loading devices.

[0037] Specifically, by sharing a set of loading devices between every two storage bins 15, the number of loading devices separately equipped for each storage bin 15 can be reduced, thereby simplifying the layout of the production line and reducing equipment costs. The shared loading device can adjust the raw materials to be delivered to different storage bins 15 as needed, thereby improving the flexibility of the production line.

[0038] In some embodiments, the storage system further includes a first controller; the first controller is used to control the opening of the first valve 7 according to the capacity requirements of each storage bin 15 so that the bucket elevator 1 switches to the discharge channel of different storage bins 15, and the raw materials are transported to the corresponding storage bin 15 through the second conveyor 8 of the corresponding discharge channel to complete the storage. In some embodiments, the storage system further includes at least one of the following: an electric hoist 5, which lifts the ton bag 2 containing the raw materials onto the unpacking machine 3; a feeding dust collector 6, which collects the dust generated during the feeding process and sends it to the bucket elevator 1 to avoid waste; and a bucket elevator outlet dust collector 13, which collects the dust generated during the discharge process to avoid dust spillage.

[0039] In some embodiments, the discharging device includes: an activation hopper 9, which is arranged at the bottom of the storage bin 15, and is used to generate vibration when discharging downward to prevent the raw materials from blocking the pipeline; a second quantitative material distribution valve 10, which is arranged at the bottom of the activation hopper 9, and is used to control the discharging speed; a third conveyor 17, which transports the raw materials in the storage bin 15 to the conveying device; a second valve 11, which is used to adjust the opening so that the storage bin 15 can be switched to connect to different third conveyors 17.

[0040] Specifically, when the raw materials in the storage bin 15 are discharged, they first pass through the activation hopper 9, which generates vibrations to prevent the raw materials from agglomerating in the storage bin 15 and causing material blockage. At the same time, the vibrations enable the raw materials to be evenly distributed and flow in the hopper, ensuring that the raw materials can be stably output at a predetermined speed and fluidity. It should be noted that the first, second, and third conveyors used in the embodiment of the present invention are conveyors of the same structure but different lengths.

[0041] In some embodiments, the storage system also includes a second controller; the second controller is used to control the opening of the second valve 11 according to the raw material demand of the batching workshop so that the storage bin 15 is switched to connect to different third conveyors 17, and the raw materials are transported to the corresponding containers of the batching workshop through the third conveyor 17.

[0042] In some embodiments, the conveying device includes: a buffer bucket 12, which is used to buffer the raw materials in the storage bin 15, and one buffer bucket 12 is shared between every two storage bins 15; a batching workshop conveyor 14, which connects the buffer bucket 12 and the batching workshop to transport the raw materials in the storage bin 15 to the batching workshop.

[0043] Specifically, every two storage bins 15 share a buffer bucket 12, and the raw materials are temporarily stored in the buffer bucket 12 and then transported to the batching workshop. This temporary storage ensures the continuity of the production process and avoids production interruptions caused by insufficient raw material supply due to equipment failure.

[0044] Figure 3 It is a flow chart of the control method of the photovoltaic glass raw material storage system disclosed in the embodiment of the present disclosure. The embodiment of the present disclosure provides a control method for the photovoltaic glass raw material storage system, and the control method includes: after the ton bag 2 containing the raw material enters the factory, the ton bag 2 containing the raw material is unpacked and loaded, and the raw material is conveyed to the bucket elevator 1 through the first quantitative material distribution valve 16 and the first conveyor 4; the bucket elevator is controlled to lift the raw material to the upper part of the storage bin 15, and according to the capacity demand of each storage bin 15, the first valve 7 and the second conveyor 8 are controlled to convey the raw material to the corresponding storage bin 15 to complete the material storage; and according to the raw material demand of the batching workshop, the second valve 11 and the third conveyor 17 are controlled to convey the raw material in the storage bin 15 to the corresponding container of the batching workshop.

[0045] Through the above technical solution, the photovoltaic glass raw material storage system and control method provided by the present disclosure uses a storage bin to store raw materials, a loading device transports the raw materials into the storage bin, a discharging device transports the raw materials in the storage bin into a conveying device, and a conveying device transports the raw materials in the discharging device to a production workshop. Thus, the storage and transportation process of photovoltaic glass raw materials is completed, overcoming the problem that the existing photovoltaic glass raw material storage occupies a large warehouse area and requires secondary transportation to the production line, saving the cost of raw material storage, and improving the efficiency and stability of production.
