Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0037] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of the present invention. Subsequent embodiments will not explain this in detail.

[0038] refer to Figures 1 to 4 This invention proposes a glass conveying device 100, comprising: a first conveying assembly 10, a transition conveying assembly 20, and a second conveying assembly 30 arranged sequentially along a conveying direction X. The transition conveying assembly 20 includes: a base 22 disposed on the first conveying assembly 10; a guide rail 24 slidably connected to the base 22, the guide rail 24 being slidable along the conveying direction X and extending from the base 22 toward the second conveying assembly 30; and a transition roller 26 disposed on the guide rail 24 (e.g., at one end of the guide rail 24 near the second conveying assembly 30). The glass conveying device 100 further includes: a first drive unit configured to drive the guide rail 24 toward the first conveying assembly 10, thereby forming a pedestrian passage between the first conveying assembly 10 and the second conveying assembly 30. A control unit configured to control the first conveying assembly 10 and the second conveying assembly 30 to stop operating in response to a first user operation.

[0039] Compared with existing technologies, the embodiments of this invention include a sliding transition conveying assembly that can slide along the conveying direction. When a pedestrian needs to cross the conveyor line, a first user operation can be performed to stop the first conveying assembly 10 and the second conveying assembly 30 from operating. Then, a pedestrian passage is formed between the first conveying assembly 10 and the second conveying assembly 30 by the drive of the first drive unit, thus easily allowing people to pass through the glass conveying line. The glass conveying device 100 has a simple structure and small size, and does not need to be raised or buried underground. After the pedestrian has passed, the guide rail 24 can move towards the second conveying assembly 30 and return to its original position. The pedestrian can then perform another user operation, causing the control unit to respond to this additional user operation and control the first conveying assembly 10 and the second conveying assembly 30 to resume operation and continue conveying the glass. The glass conveying device 100 may include a first button 60, and the first user operation can be the operation of the first button 60.

[0040] In some embodiments, the first drive unit is a handle 28, which is operated by a pedestrian to drive the guide rail 24 to move. This eliminates the need for additional electrical drive components and simplifies the structure of the device. The handle 28 may be mounted on the transition roller 26.

[0041] In some embodiments, the transition roller 26 is not equipped with a drive component. Since the glass can already be moved by means of the first conveying assembly 10 and the second conveying assembly 30, the transition roller 26 mainly serves as a transition to prevent the gap between the first conveying assembly 10 and the second conveying assembly 30 from being too large. Therefore, no driving force needs to be provided to the transition roller 26, which can further simplify the structure.

[0042] In some embodiments, the transition conveying assembly 20 further includes a return spring 21 disposed between the first conveying assembly 10 and the transition roller 26. When the guide rail 24 slides toward the first conveying assembly 10, the return spring 21 is compressed; when the first drive unit no longer provides driving force, the return spring 21 extends, causing the guide rail 24 to move toward the second conveying assembly 30 and reset. The transition conveying assembly 20 may also include a guide post 23 disposed on the first conveying assembly 10, the guide post 23 being used to guide the return spring 21 to extend and retract along the conveying direction X.

[0043] In some embodiments, the first conveying assembly 10 includes: a first frame 12, a first roller 14 disposed on the first frame 12, and a first motor 16 driving the first roller 14 to rotate. The first conveying assembly 10 serves as a workpiece input device, responsible for receiving glass workpieces from upstream. The base 22 can be disposed on the first frame 12, thus eliminating the need for additional mounting components, allowing for a more compact structure and reducing the overall size of the device. The first conveying assembly 10 may also include a first drive shaft 11 and a first bevel gear 13.

[0044] In some embodiments, the second conveying assembly 30 includes: a mounting portion 32; a support portion 34 (e.g., a frame structure) disposed between the transition conveying assembly 20 and the mounting portion 32, one side of the support portion 34 being rotatably connected to the mounting portion 32 via a pivot 342; a conveying portion 36 disposed on the support portion 34; a second drive portion configured to drive the support portion 34 to rotate relative to the pivot 342, thereby switching the support portion 34 between a working position and a flipped position; when in the working position, the support portion 34 is disposed along the conveying direction X; when in the flipped position, a vehicle passage is formed between the transition conveying assembly 20 and the mounting portion 32; and a control portion further configured to control the first conveying assembly 10 and the second conveying assembly 30 to stop working in response to a second user operation, and to control the second drive portion to drive the support portion 34 to rotate to the flipped position.

[0045] When a vehicle needs to pass through the conveyor line, a second user operation can be performed to stop the first conveying assembly 10 and the second conveying assembly 30 from working, and control the second drive unit to drive the carrier 34 to rotate to the flip position, thereby forming a vehicle passage between the transition conveying assembly 20 and the mounting part 32. This allows vehicles to easily pass through the glass conveyor line. The glass conveying device 100 has a simple structure and small size, and does not need to be raised or buried underground. After the vehicle has passed, another user operation can be performed, causing the control unit to respond to the additional user operation by controlling the second drive unit to drive the carrier 34 to the working position, and controlling the first conveying assembly 10 and the second conveying assembly 30 to resume working and continue conveying glass. The glass conveying device 100 may include a second button 62, and the second user operation can be the operation of the second button 62.

[0046] In some embodiments, the second driving unit is a cylinder 38. The fixed end of the cylinder 38 is hinged to the mounting part 32, and the telescopic end of the cylinder 38 is hinged to the support part 34. When the cylinder 38 is in the retracted state, the support part 34 is in the working position, and the cylinder 38 is obliquely disposed between the mounting part 32 and the support part 34 (the cylinder 38, the support part 34, and the mounting part 32 can form a triangular structure). When the cylinder 38 is in the extended state, the support part 34 is in the flipped position. After flipping upward, the support part 34 is in a roughly vertical state, and the cylinder 38 is also in a roughly vertical state (the cylinder 38, the support part 34, and the mounting part 32 are roughly located on the same vertical line). The fixed end of the cylinder 38 can be hinged through the first hinge support 382, ​​and the telescopic end of the cylinder 38 can be hinged through the second hinge support 384.

[0047] In some embodiments, the conveying unit 36 ​​is a synchronous belt conveying assembly, which may include a synchronous belt 362 and a synchronous belt drive unit 364. By using a synchronous belt conveying assembly, the weight can be reduced, the burden on the carrying unit 34 can be reduced, and the rotation of the carrying unit 34 can be facilitated; furthermore, the synchronous belt conveying assembly may only include a synchronous belt drive unit 364 located on one side, without affecting the rotation of the carrying unit 34.

[0048] In some embodiments, the glass conveying device 100 further includes a third conveying assembly 40, which is disposed downstream of the second conveying assembly 30 along the conveying direction X and includes: a second frame 42, a second roller 44 disposed on the second frame 42, and a second motor 46 for driving the second roller 44 to rotate. By providing the third conveying assembly 40, the required conveying distance can be ensured, making it suitable for conveying larger sizes of glass. The third conveying assembly 40 can serve as a workpiece output device, responsible for outputting glass panel workpieces downstream. The third conveying assembly 40 may also include a second drive shaft 41 and a second bevel gear 43.

[0049] In some embodiments, the second frame 42 provides a mounting portion 32, that is, the support portion 34 and the cylinder 38 are disposed on one side of the second frame 42. This eliminates the need for additional mounting components, which helps to simplify the structure and reduce the size of the device. The first button 60 and the second button 62 may be disposed on the second frame 42.

[0050] In some embodiments, the glass conveying device 100 further includes a protective light curtain 50, and the control unit is configured to issue an alarm in response to the absence of a first user operation and a second user operation, and when the protective light curtain 50 detects the approach of a pedestrian or vehicle. This protects the normal operation of the equipment and the safety of personnel. The protective light curtain 50 can be mounted to the first frame 12 and / or the second frame 42 via a mounting bracket 52.

[0051] Before using the glass conveying device 100, it should be checked that the upper surfaces of the first roller 14, the transition roller 26, the synchronous belt conveying assembly, and the second roller 44 are on the same plane to ensure that the glass panel workpiece can be conveyed normally along this plane.

[0052] When personnel need to pass through the conveyor line, they should first ensure that there are no glass workpieces on the glass conveying device 100 or wait until the glass workpieces have been conveyed. Then, press the first button 60. At this time, the synchronous belt conveyor assembly, the first motor 16, and the first roller 14 will stop operating. Personnel can then use the operating handle 28 to move the guide rail 24 in the direction of material arrival, allowing them to pass through. After personnel have passed, the guide rail 24 returns to its initial position under the action of the return spring 21. Then, pressing the same first button 60 on the opposite side will start the synchronous belt conveyor assembly, the first motor 16, and the first roller 14, allowing them to operate normally.

[0053] When a transfer vehicle needs to pass through the conveyor line, first ensure that there are no glass workpieces on the glass conveying device 100 or wait until the glass workpieces have been conveyed. Then press the second button 62. At this time, the synchronous belt conveyor assembly, the first motor 16, and the first roller 14 will stop operating. Simultaneously, the cylinder 38 will lift the bearing part 34, causing the bearing part 34 to rotate around the pivot 342, allowing the transfer vehicle to pass. After the vehicle passes, the operator presses the same second button 62 on the opposite side. The cylinder 38 retracts, and the bearing part 34 returns to its initial horizontal state. The synchronous belt conveyor assembly, the first motor 16, and the first roller 14 will then start and operate normally.

[0054] If the corresponding button is not pressed and the vehicle forces its way through, the protective light curtain 50 will detect this and issue an audible and visual alarm.

[0055] In summary, the technical solution of this invention can meet the automation needs of glass panel production lines, realize the function of continuous product conveying, and the conveying device can be easily adjusted to facilitate the passage of personnel and transport vehicles. After personnel and vehicles have passed, the device can be easily restored to its original state.
