Description

Technical Field

[0001] This invention relates to the field of glass production technology, and more specifically to a multi-channel conveying device for glass sheets. Background Technology

[0002] Photovoltaic glass is a special type of glass used in solar photovoltaic modules. It is mainly divided into two categories: crystalline silicon photovoltaic glass (including monocrystalline silicon and polycrystalline silicon) and thin-film photovoltaic glass. It is used in building-integrated photovoltaics (BIPV) applications such as solar smart windows and photovoltaic curtain walls. Its mainstream products include ultra-clear rolled glass and AR coated glass, which need to have high light transmittance and weather resistance to protect photovoltaic cells.

[0003] The production process of photovoltaic glass generally includes steps such as raw material crushing, weighing, mixing, melting, rolling, annealing, inspection, and slitting. In existing technology, after the glass is slitting, it can be conveyed backward using a three-channel conveying method (three glass sheets arranged side by side). During the conveying process, one or more glass sheets that are found to be abnormal need to be sent to a crushing device.

[0004] For example, patent application number CN202121450618.X discloses a multi-level sorting system for raw glass sheets, including a glass conveying device arranged in a front-to-back direction and a detection device and a cutting device arranged sequentially on the glass conveying device from front to back; it also includes a crushing device, a grading device and a sampling platform arranged sequentially from front to back, wherein the grading device is composed of multiple grading units connected in series; the crushing device includes a front layer conveying structure, a crushing structure and a front upper layer conveying structure and a front lower layer conveying structure arranged side by side, wherein the front upper layer conveying structure and the front lower layer conveying structure are located directly behind the front layer conveying structure and are both arranged in a front-to-back direction; the front layer conveying structure is arranged in a front-to-back direction, its front end is connected to the rear end of the glass conveying device and its rotation is mounted on a corresponding flipping shaft, and its rear end can move up and down and is connected to the front end of the front upper layer conveying structure and the front end of the front lower layer conveying structure respectively; the crushing structure is located at the rear end of the front lower layer conveying structure. The grading unit includes a rear layer conveying structure, a transverse reversing conveying structure, and a rear upper layer conveying structure and a rear lower layer conveying structure arranged side by side. The rear upper layer conveying structure and the rear lower layer conveying structure are both located directly behind the rear layer conveying structure and are arranged in the front-back direction. The rear layer conveying structure is arranged in the front-back direction, with its front end rotatably mounted on a corresponding flipping shaft, and its rear end can move up and down. The front end of the rear layer conveying structure of the first-level grading unit is connected to the rear end of the front upper layer conveying structure, and the front end of the rear layer conveying structure of the remaining grading units is connected to the rear end of the rear lower layer conveying structure of the previous level. When the rear end of the rear layer conveying structure moves up and down, it is connected to the front end of the rear upper layer conveying structure and the front end of the rear lower layer conveying structure, respectively. The sampling platform is located at the rear end of the rear lower layer conveying structure of the last grading unit. The rear end of the rear upper layer conveying structure is provided with a positioning baffle in the left-right direction, and its rear part is provided with a transverse reversing conveying structure that outputs the glass in the left-right direction. The front upper layer conveying structure is arranged obliquely upward from front to back, and the front lower layer conveying structure is arranged obliquely downward from front to back; the front part of the rear upper layer conveying structure is arranged obliquely upward from front to back and its rear part is arranged horizontally, and the rear lower layer conveying structure is arranged horizontally; when the rear layer conveying structure is flipped to the low position, it is horizontal and flush with the rear lower layer conveying structure; when the rear layer conveying structure is flipped to the high position, it is located on the same inclined plane as the front part of the corresponding rear upper layer conveying structure; the transverse reversing conveying structure is arranged below the rear upper layer conveying structure along the left and right direction and can move upward to above the rear upper layer conveying structure.Both the front-layer conveying structure and the rear-layer conveying structure include a tilting shaft arranged in the left-right direction, multiple fixed conveying arms arranged side by side in the left-right direction, multiple lifting conveying arms arranged side by side in the left-right direction, a drive motor that drives the tilting shaft to rotate, and a lifting mechanism that synchronously drives the multiple lifting conveying arms to move up and down. The fixed conveying arms and the lifting conveying arms are arranged alternately. The fixed conveying arms are horizontally fixed and their chains are connected to the tilting shaft for transmission. The front end of the lifting conveying arms is rotatably connected to the tilting shaft and its chains are connected to the tilting shaft for transmission. The multiple fixed conveying arms are coplanar and are all arranged horizontally in the front-back direction. The multiple lifting conveying arms are coplanar and are all arranged in the front-back direction. When they are in a low position, they are coplanar with the fixed conveying arms. When they are in a high position, they are tilted above the fixed conveying arms.

[0005] Existing multi-channel conveying devices include a frame and a feeding conveyor structure, a tilting conveyor structure, and an output conveyor structure arranged sequentially from front to back. The tilting conveyor structure can rotate downwards and has a tilting support structure directly below its rear. Both the feeding and output conveyor structures can convey three glass sheets simultaneously. The tilting conveyor structure includes three tilting conveyor mechanisms arranged side by side. Each tilting conveyor mechanism is driven to convey and tilt independently, which requires three conveyor drive motors and three reverse drive structures, resulting in a complex structure.

When the second cylinder extends, the second swing arm rotates backwards to an angled upwards from front to back, and the second support arm 7 rotates backwards.

[0037] Specifically, the first cylinder is thicker than the second cylinder. Both the first drive mechanism 8 and the second drive mechanism 9 are equipped with rotation angle limiting structures to control the rotation angle of the bushing 4 and the long rotating shaft 5, ensuring the stability of the conveying process. This is a conventional structure, and a detailed description is omitted in this embodiment.
