[0002] Photovoltaic glass, as an important material for photovoltaic modules, raw material batching is the first step in the production of photovoltaic glass. Before the preparation of the batch material, it is necessary to prepare the raw materials required for the preparation of the batch material. The production line workshop for the preparation of the batch material is usually a three-dimensional structure, and a silo is arranged on the top floor of the workshop for storing the raw materials required for batching on the same day.

[0003] With the development of the photovoltaic industry, the production scale of the photovoltaic glass production line has been continuously improved, and the amount of raw materials required per day has been increasing. In the prior art, a bucket elevator and manual labor are conventionally used to transport the raw materials into the silo on the top floor of the workshop, which requires a large amount of labor and has a high labor intensity. The daily transportation volume is difficult to meet the amount of raw materials required by the current production scale. Summary of the Utility Model

[0005] Another technical problem solved by the present disclosure is to provide a production line for photovoltaic glass, which has a high efficiency in transporting raw materials and a low labor intensity.

[0006] To solve the above technical problems, an embodiment of the present disclosure provides a raw material feeding system for photovoltaic glass, which includes:

[0007] A first material transport vehicle;

[0008] A second material transport vehicle; and,

[0009] A conveyor, the conveyor includes at least two docking ports arranged vertically in the height direction, and the two docking ports include a first docking port for docking with the first material transport vehicle and a second docking port for docking with the second material transport vehicle, and the second docking port is located above the first docking port;

[0010] Wherein, the first material transport vehicle is used to transport the material to the first docking port, the conveyor is used to convey the material at the first docking port to the second docking port, and the second material transport vehicle is used to transport the material at the second docking port to a predetermined position.

[0011] In some embodiments, the conveyor includes a hoist feeding conveyor, a hoist discharging conveyor, and a hoist. The hoist is arranged vertically in the height direction corresponding to the hoist docking interfaces. The hoist docking interfaces include a first hoist docking interface for docking with the hoist feeding conveyor and a second hoist docking interface for docking with the hoist discharging conveyor. The second hoist docking interface is located above the first hoist docking interface. One end of the hoist feeding conveyor away from the hoist is docked with a first transport vehicle, and one end of the hoist discharging conveyor away from the hoist is docked with a second transport vehicle.

[0012] In some embodiments, both the hoist feeding conveyor and the hoist discharging conveyor include a conveyor main body, a conveyor idler drive, and a plurality of conveyor idlers arranged in sequence from the conveyor main body inlet to the conveyor main body outlet. The conveyor idler drive is used to drive the conveyor idlers to rotate.

[0013] In some embodiments, the hoist includes a hoisting mechanism, a conveying mechanism, and a car. The hoisting mechanism is used to drive the car to move between the first hoist docking interface and the second hoist docking interface. The conveying mechanism is used to convey the materials on the hoist feeding conveyor into the car, and to convey the materials in the car onto the hoist discharging conveyor.

[0014] In some embodiments, the conveying mechanism includes hoist idlers and a hoist idler drive. The hoist idlers are arranged at the bottom of the car, and the hoist idler drive is used to drive the hoist idlers to rotate.

[0015] In some embodiments, the hoisting mechanism includes a hoisting chain and a hoisting chain drive. The hoisting chain drive is used to drive the hoisting chain to drive the car to move between the first hoist docking interface and the second hoist docking interface.

[0016] In some embodiments, the second transport vehicle is an intelligent forklift. A position sensor is provided at the second docking interface of the conveyor. The position sensor is used to detect whether the material reaches the second docking interface of the conveyor. The intelligent forklift is used to convey the material at the second docking interface of the conveyor to a predetermined position in response to the in-place signal sent by the position sensor.

[0017] In some embodiments, a lower in-place sensor of the hoist is provided at a position of the hoist close to the hoist feeding conveyor. The hoist feeding conveyor conveys the material at the inlet of the hoist feeding conveyor to the outlet of the hoist feeding conveyor in response to the lower in-place signal of the hoist sent by the lower in-place sensor of the hoist. The hoisting mechanism is used to stop the downward movement of the car in response to the lower in-place signal. An upper in-place sensor of the hoist is provided at a position of the hoist close to the hoist discharging conveyor. The hoisting mechanism is used to stop the upward movement of the car in response to the upper in-place signal of the hoist sent by the upper in-place sensor of the hoist.

[0021] Through the above technical solutions, the conveyor of the feeding system for photovoltaic glass raw materials provided by the present disclosure is compared with the bucket elevator used in the prior art. The bucket elevator can only transport bulk raw materials and is not suitable for transporting boxed materials or tray-mounted raw materials. After the bucket elevator transports the bulk materials to the second floor, the bulk raw materials are not suitable for direct transportation and need to be manually packaged and transported, resulting in a high labor intensity and low efficiency. However, the materials transported by the conveyor of the present disclosure include containers and photovoltaic glass raw materials arranged in the containers, and the second transport vehicle can directly transport the materials at the conveyor outlet to the predetermined position, reducing the labor intensity of workers and improving the conveying efficiency.

[0034] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification.

[0035] Such as Figure 1As shown in the figure, the feeding system for photovoltaic glass raw materials of the present disclosure includes a first floor 1, a second floor 2, a first transport vehicle 3, a second transport vehicle 4, and a conveyor. The second floor 2 is above the first floor 1. The first transport vehicle 3 is arranged on the first floor 1, and the second transport vehicle 4 is arranged on the second floor 2. The second floor 2 is above the first floor 1. The first docking port and the second docking port of the conveyor are the inlet and the outlet respectively. The first transport vehicle 3 can transport the materials to the inlet of the conveyor. The conveyor transports the boxed or palletized raw materials at its inlet to its outlet, that is, the conveyor transports the boxed or palletized raw materials from the first floor 1 to the second floor 2. The second transport vehicle 4 transports the materials at the outlet of the conveyor to the designated position on the second floor 2. Thus, the feeding system for photovoltaic glass raw materials of the present disclosure can transport the raw materials on the first floor 1 to the designated position on the second floor 2, and the designated position is adjusted according to actual requirements. In some embodiments, a raw material bin 20 for storing raw materials is arranged on the second floor 2, and the designated position is set to be close to the raw material bin 20. The materials of the present disclosure are boxed or palletized raw materials. Compared with the prior art solution of using a bucket elevator and manual labor to transport the raw materials to the second floor 2, the bucket elevator is not suitable for transporting boxed or palletized raw materials. The bucket elevator can only transport the bulk raw materials to the second floor 2, and manual labor is required to package and handle the bulk raw materials, resulting in low transportation efficiency and high labor intensity. However, the conveyor of the present disclosure can directly transport the boxed or palletized raw materials from the first floor 1 to the second floor 2, and uses the first transport vehicle 3 to transport the materials to the inlet of the conveyor, and uses the second transport vehicle 4 to transport the materials at the outlet of the conveyor to the designated position on the second floor 2, with higher transportation efficiency and lower labor intensity.

[0036] In some embodiments, as Figure 1 shown, the conveyor includes a hoist feeding conveyor 5 arranged on the first floor 1, a hoist discharging conveyor 6 arranged on the second floor 2, and a hoist 7. The hoist 7 is arranged vertically in the height direction with hoist docking ports corresponding to the docking ports. The hoist docking ports include a first hoist docking port for docking with the hoist feeding conveyor 5 and a second hoist docking port for docking with the hoist discharging conveyor 6. The second hoist docking port is above the first hoist docking port. That is, the inlet of the hoist feeding conveyor 5 is docked with the first transport vehicle 3, the outlet of the hoist feeding conveyor 5 is docked with the inlet of the hoist 7, the outlet of the hoist 7 is docked with the inlet of the hoist discharging conveyor 6, and the outlet of the hoist discharging conveyor 6 is docked with the second transport vehicle 4. The first transport vehicle 3 is used to transport the boxed or palletized raw materials to the inlet of the hoist feeding conveyor 5. The boxed or palletized raw materials are successively transported through the hoist feeding conveyor 5, the hoist 7, and the hoist discharging conveyor 6, from the inlet of the hoist feeding conveyor 5 to the outlet of the hoist discharging conveyor 6. The second transport vehicle 4 is used to transport the materials at the outlet of the hoist discharging conveyor 6 to the predetermined position.

[0037] In some embodiments, such as Figure 1 and Figure 3 shown, the hoist loading conveyor 5 and the hoist discharging conveyor 6 both include a conveyor main body 8, a conveyor idler drive 9, and a plurality of conveyor idlers 10 arranged in sequence from the inlet of the conveyor main body 8 to the outlet of the conveyor main body 8. The conveyor idler drive 9 is used to drive the conveyor idlers 10 to rotate. In some embodiments, the plurality of conveyor idlers 10 are connected by a belt, and the conveyor idler drive 9 is a conveyor idler drive motor. The conveyor idler drive motor drives the plurality of conveyor idlers 10 to rotate synchronously to drive boxed or palletized raw materials to move from the inlet of the conveyor main body 8 to the outlet of the conveyor main body 8.

[0038] In some embodiments, such as Figure 1 and Figure 2 shown, the hoist 7 includes a lifting mechanism, a conveying mechanism, and a car 11. The lifting mechanism is used to drive the car 11 to move between a first state and a second state. When the car 11 is in the first state, the car 11 is connected to the hoist loading conveyor 5 through the conveying mechanism, and the conveying mechanism is used to convey boxed or palletized raw materials at the outlet of the hoist loading conveyor 5 into the car 11. When the car 11 is in the second state, the car 11 is connected to the hoist discharging conveyor 6 through the conveying mechanism, and the conveying mechanism is used to convey boxed or palletized raw materials in the car 11 to the inlet of the hoist discharging conveyor 6.

[0039] In some embodiments, such as Figure 1 and Figure 2 shown, the conveying mechanism includes a plurality of hoist idlers 12 and a hoist idler drive 13. The plurality of hoist idlers 12 are arranged side by side in sequence from the side close to the hoist loading conveyor 5 to the opposite side at the bottom of the car 11. The plurality of hoist idlers 12 are connected by a belt. The hoist idler drive 13 is a hoist idler drive motor. The hoist idler drive motor drives the plurality of hoist idlers 12 to rotate synchronously to drive boxed or palletized raw materials at the outlet of the hoist loading conveyor 5 to move into the car 11 or drive boxed or palletized raw materials in the car 11 to move to the inlet of the hoist discharging conveyor 6 through the hoist idlers 12.

[0040] In some embodiments, such as Figure 1 shown, the lifting mechanism includes a lifting chain 14 and a lifting chain drive 15. The lifting chain drive 15 is used to drive the lifting chain 14 to drive the car 11 to move between the first state and the second state.

[0041] In some embodiments, the second material transporter 4 is an intelligent forklift. A position sensor 16 is provided at the outlet of the conveyor. The position sensor 16 is used to detect whether the boxed or palletized raw materials have reached the outlet of the conveyor. When the boxed or palletized materials are transported to the outlet of the conveyor, the position sensor at the outlet of the conveyor sends a signal indicating that the materials have arrived. The intelligent forklift responds to the signal indicating that the materials have arrived sent by the position sensor 16 and transports the boxed or palletized raw materials at the outlet of the conveyor to a predetermined position, thereby automatically transporting the materials at the outlet of the conveyor to the designated position by the intelligent forklift. In some other embodiments, both the first material transporter 3 and the second material transporter are intelligent forklifts, realizing automatic continuous feeding of photovoltaic glass raw materials with relatively high efficiency.

[0042] In some embodiments, as Figure 1 shown, a lower hoist in-place sensor 17 is provided at a position where the hoist 7 is close to the hoist feeding conveyor 5. The hoist feeding conveyor 5 responds to the lower hoist in-place signal sent by the lower hoist in-place sensor 17 and transports the boxed or palletized raw materials at the inlet of the hoist feeding conveyor 5 to the outlet of the hoist feeding conveyor 5. The hoisting mechanism is used to respond to the lower hoist in-place signal to stop the downward movement of the car 11. A upper hoist in-place sensor 18 is provided at a position where the hoist 7 is close to the hoist discharging conveyor 6. The hoisting mechanism is used to respond to the upper hoist in-place signal sent by the upper hoist in-place sensor 18 to stop the upward movement of the car 11, thereby realizing the movement of the car between the first state and the second state. When the car 11 has not moved to the first floor, the hoist feeding conveyor 5 will not transport materials to the hoist 7, avoiding material dropping.

[0043] In some embodiments, as Figure 1 shown, the photovoltaic glass raw material feeding system of the present disclosure further includes a control system 19. The control system 19 is used to control the intelligent forklift, the hoist feeding conveyor 5, the hoist discharging conveyor 6, and the hoist 7 to transport boxed or palletized raw materials.

[0044] Based on the photovoltaic glass raw material feeding system mentioned in the above technical solution of the present disclosure, the present disclosure further provides a photovoltaic glass production line, and this photovoltaic glass production line includes the above photovoltaic glass raw material feeding system of the present disclosure.

[0045] As can be seen from the above description, the advantages of the present disclosure are that it realizes automatic continuous feeding, increases the daily material transportation volume, and reduces the problem of large labor intensity of manual feeding.

To avoid obscuring the concept of the present disclosure, some details well known in the art have not been described. Those skilled in the art can clearly understand how to implement the technical solutions disclosed here based on the above description.
