Description

Technical Field

[0001] This invention relates to the field of glass conveying technology, and in particular to a 90-degree vertically lifting and turning conveying device. Background Technology

[0002] In glass deep-processing production lines, 90-degree steering devices play a crucial role in glass conveying and processing. Currently, most of these devices use crank-connecting rod mechanisms to achieve lifting functions. However, this traditional lifting method has many drawbacks. During lifting, because the crank-connecting rod travels in an arc, horizontal swaying occurs. When the glass is lifted on the conveyor belt assembly, slippage and swaying are very likely to occur. For processing stages that require high precision in glass plate positioning, existing 90-degree steering devices using crank-connecting rod mechanisms struggle to achieve accurate positioning, thus affecting the quality and efficiency of glass deep processing. Summary of the Invention

[0003] The purpose of this invention is to provide a vertically lifting and lowering 90-degree turning conveyor to solve the above-mentioned technical problems.

[0004] The technical solution adopted in this invention is as follows: A vertically lifting and lowering 90-degree turning conveyor includes a roller conveyor component, a lifting mechanism, a belt conveyor mechanism, and an alignment mechanism. The lifting mechanism is located inside the roller conveyor component, the belt conveyor mechanism is located at the upper end of the lifting mechanism, and the alignment mechanism is located at one end of the belt conveyor mechanism. The conveying direction of the roller conveyor component is perpendicular to the conveying direction of the belt conveyor mechanism. The lifting mechanism includes a lifting outrigger frame, lifting cylinders, crank guide mechanisms, and linear bearings. Four linear bearings are symmetrically arranged on both sides of the lifting outrigger frame. Each crank guide mechanism is slidably connected to one of the linear bearings. Two lifting cylinders are symmetrically distributed on both sides of the lifting outrigger frame. The output end of each lifting cylinder is connected to the corresponding crank guide mechanism. Each crank guide mechanism is connected to the lower end of the belt conveyor mechanism.

[0005] Preferably, the crank guide mechanism includes a power crank component, a double-hinged connecting rod assembly, a guide shaft assembly, and a first rotating shaft. The middle portions of the two power crank components, located on both sides of the lifting outrigger frame and facing each other, are connected by the first rotating shaft. The first rotating shaft is rotatably mounted on the lifting outrigger frame via a bearing seat. The output end of the lifting cylinder is connected to one end of the power crank component, the other end of the power crank component is connected to one end of the double-hinged connecting rod assembly, the other end of the double-hinged connecting rod assembly is connected to one end of the guide shaft assembly, the guide shaft assembly passes through the linear bearing, and the other end of the guide shaft assembly is connected to the belt conveyor mechanism.

[0006] As a further preferred embodiment, the double-hinged connecting rod assembly includes a connecting handle, a spherical bearing, a first connecting rod, a first connecting shaft, and a second connecting shaft. The two ends of the first connecting rod are threadedly connected to the two connecting handles. Each connecting handle is provided with a spherical bearing. The other end of the power crank is rotatably connected to one of the spherical bearings via the first connecting shaft. The guide shaft assembly is rotatably connected to the other spherical bearing via the second connecting shaft.

[0007] As a further preferred embodiment, the guide shaft assembly includes a guide shaft, an end flange, and a connecting seat. The connecting seat is provided at one end of the guide shaft, and the end flange is provided at the other end of the guide shaft. The end flange is connected to the belt conveyor mechanism. The guide shaft passes through the linear bearing, and the connecting seat is rotatably connected to the spherical bearing via a second connecting shaft.

[0008] As a further preferred embodiment, a second connecting rod is also included, through which the two power crank components located on the same side are rotatably connected.

[0009] Preferably, the alignment mechanism includes a support base, a support beam, a lifting cylinder, and a stop mechanism. The support base is connected to one end of the belt conveyor mechanism. The support beam is provided at the upper end of the support base. The lifting cylinder is provided on one side of the support base. The stop mechanism is provided on the support beam. The output end of the lifting cylinder is rotatably connected to one end of the stop mechanism.

[0010] As a further preferred embodiment, the stop mechanism includes a crank, a rotating shaft, and a first support. Two first supports are provided on one side of the support beam, and a crank is rotatably disposed in each first support. The middle parts of the two cranks are connected by the rotating shaft, and one end of the crank is rotatably connected to the output end of the lifting cylinder.

[0013] The above technical solution has the following advantages or beneficial effects: In this invention, the alignment mechanism improves the positioning accuracy of the glass during transport. This mechanism accurately aligns the glass before it enters the turning and conveying stage, ensuring it is in a precise position. Furthermore, the lifting mechanism uses linear bearings for guidance, guaranteeing vertical lifting of the belt conveyor and preventing skewing or slippage of the glass during lifting, thus maintaining its precise position throughout the entire transport process.

[0014] In this invention, the lifting cylinders arranged symmetrically on both sides of the lifting mechanism work together to quickly drive the belt conveyor assembly to rise and fall vertically, greatly improving the glass transmission efficiency.

[0015] In this invention, the double-hinged support rod assembly in the lifting mechanism is connected using spherical bearings. This reduces jamming during the lifting process. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] Please see Figures 1 to 7The diagram illustrates a preferred embodiment of a vertically lifting and lowering 90-degree turning conveyor device, comprising a roller conveyor component 1, a lifting mechanism 2, a belt conveyor mechanism 3, and an alignment mechanism 4. The lifting mechanism 2 is located inside the roller conveyor component 1, and the belt conveyor mechanism 3 is located at the upper end of the lifting mechanism 2. The alignment mechanism 4 is located at one end of the belt conveyor mechanism 3. The conveying direction of the roller conveyor component 1 is perpendicular to the conveying direction of the belt conveyor mechanism 3. In this embodiment, the roller conveyor component 1 conveys glass along a first direction, while the belt conveyor mechanism 3 conveys glass along a second direction, with the first and second directions perpendicular. The lifting mechanism 2 drives the belt conveyor mechanism 3 to move up and down, achieving vertical lifting and lowering. The alignment mechanism 4 prevents the glass from moving, causing it to remain on the belt conveyor mechanism 3 before being conveyed out by it, thus achieving a 90-degree turn of the glass.

[0022] The lifting mechanism 2 includes a lifting leg frame 21, lifting cylinders 22, crank guide mechanisms, and linear bearings 26. Four linear bearings 26 are symmetrically arranged on both sides of the lifting leg frame 21. Each crank guide mechanism is slidably connected to a linear bearing 26. Two lifting cylinders 22 are symmetrically distributed on both sides of the lifting leg frame 21. The output end of each lifting cylinder 22 is connected to a corresponding crank guide mechanism, and each crank guide mechanism is connected to the lower end of the belt conveyor mechanism 3. In this embodiment, the linear bearings 26 are fixed to the lifting leg frame 21 to provide guidance for the movement of the crank guide mechanisms, allowing the crank guide mechanisms to move vertically up and down, thereby driving the belt conveyor mechanism 3 to move vertically up and down, preventing the glass on the belt conveyor mechanism 3 from tilting or slipping. The lifting cylinders 22 are rotatably connected to the side walls of the lifting leg frame 21 via pins.

[0023] In this embodiment, the linear bearing 26 and the crank guide mechanism work together to enable the belt conveyor 3 to move vertically, preventing glass slippage and skew due to horizontal sway. Furthermore, the symmetrically arranged lifting cylinders 22 work together to quickly drive the belt conveyor assembly 3 to move vertically, improving glass transport efficiency and meeting the requirements of high-precision glass processing for glass positioning and transport efficiency.

[0024] Furthermore, as a preferred embodiment, the crank guide mechanism includes a power crank component 23, a double-hinged connecting rod assembly 25, a guide shaft assembly 27, and a first rotating shaft 28. The two power crank components 23, located on opposite sides of the lifting outrigger frame 21 and facing each other, are connected at their midpoints via the first rotating shaft 28. The first rotating shaft 28 is rotatably mounted on the lifting outrigger frame 21 via a bearing seat. The output end of the lifting cylinder 22 is connected to one end of the power crank component 23, and the other end of the power crank component 23 is connected to one end of the double-hinged connecting rod assembly 25. The other end of the double-hinged connecting rod assembly 25 is connected to one end of the guide shaft assembly 27. The guide shaft assembly 27 passes through a linear bearing 26, and the other end of the guide shaft assembly 27 is connected to the belt conveyor mechanism 3. In this embodiment, see [reference needed]. Figure 2 and Figure 3 As shown, when the lifting cylinder 22 drives the power crank 23 to rotate, the power crank 23 can drive the double-hinged connecting rod assembly 25 to rotate, causing the double-hinged connecting rod assembly 25 to drive the guide shaft assembly 27 to move. Due to the linear bearing 26, the guide shaft assembly 27 can only move vertically up and down, thereby realizing the lifting action of the belt conveyor mechanism 3. The bearing seat can fix the position of the first rotating shaft 28, allowing the first rotating shaft 28 to rotate without horizontal slippage. The first rotating shaft 28 connects the two power cranks 23, ensuring that the two power cranks 23 rotate synchronously and in the same direction. See also... Figure 3 As shown, it also includes a second connecting rod 24, which rotatably connects the two power crank components 23 located on the same side. With the arrangement of the first rotating shaft 28 and the second connecting rod 24, and using two lifting cylinders 22, the four power crank components 23 can be driven to rotate synchronously and in the same direction, thereby ensuring the levelness of the glass on the belt conveyor mechanism 3 and enhancing the stability of the entire mechanism.

[0025] Furthermore, as a preferred embodiment, the double-hinged connecting rod assembly 25 includes a connecting handle 251, a spherical bearing 252, a first connecting rod 253, a first connecting shaft, and a second connecting shaft. Both ends of the first connecting rod 253 are threadedly connected to the two connecting handles 251. Each connecting handle 251 contains a spherical bearing 252. The other end of the power crank component 23 is rotatably connected to a spherical bearing 252 via the first connecting shaft. The guide shaft assembly 27 is rotatably connected to another spherical bearing 252 via the second connecting shaft. The spherical bearings 252 prevent jamming during lifting. By rotating the first connecting rod 253, the end of the connecting rod pushes the spherical bearing 252, thus adjusting the center distance between the two spherical bearings 252. The first and second connecting shafts enable rotation between the power crank component 23, the spherical bearings 252, and the guide shaft assembly 27.

[0026] Furthermore, as a preferred embodiment, the guide shaft assembly 27 includes a guide shaft, an end flange, and a connecting seat. One end of the guide shaft is provided with the connecting seat, and the other end is provided with the end flange. The end flange is connected to the belt conveyor mechanism 3. The guide shaft passes through the linear bearing 26, and the connecting seat is rotatably connected to the spherical bearing 252 via a second connecting shaft. The flange is bolted to the bottom frame of the belt conveyor mechanism 3. The guide shaft cooperates with the linear bearing 26, allowing the guide shaft to move only up and down, facilitating the lifting and lowering of the belt conveyor mechanism 3.

[0027] Furthermore, as a preferred embodiment, the alignment mechanism 4 includes a support base 490, a support beam 41, a lifting cylinder 43, and a stop mechanism. The support base 490 is connected to one end of the belt conveyor mechanism 3. The support beam 41 is provided at the upper end of the support base 490, and the lifting cylinder 43 is provided on one side of the support base 490. The stop mechanism is provided on the support beam 41, and the output end of the lifting cylinder 43 is rotatably connected to one end of the stop mechanism. The stop mechanism includes a crank 44, a rotating shaft 42, and a first support 49. Two first supports 49 are provided on one side of the support beam 41, and a crank 44 is rotatably provided in each first support 49. The middle parts of the two cranks 44 are connected by the rotating shaft 42, and one end of the crank 44 is rotatably connected to the output end of the lifting cylinder 43. One end of the third connecting rod 45 is rotatably connected to the other end of the crank 44, and the other end of the third connecting rod 45 is rotatably connected to the middle of the fourth connecting rod 46. One end of each of the two fourth connecting rods 46 is connected by an alignment stop. Two second supports 47 are provided at the upper end of the support beam 41, and the other end of each fourth connecting rod 46 is rotatably connected to one of the second supports 47. When the glass plate enters the roller conveyor component 1 via the main line and decelerates forward, the lifting cylinder 43 actuates, driving the crank 44 to rotate around the rotating shaft 42. This, through the third connecting rod 45, causes the fourth connecting rod 46 and the alignment stop to flip up, decelerating the glass and bringing it to a stop, thus achieving precise alignment of the glass. Through the coordinated action of the stop mechanism and the lifting cylinder 43, the glass can be accurately positioned, ensuring that it is in a precise position before entering the turning conveyor stage, providing a guarantee for subsequent 90-degree turning conveyor and high-precision processing. The alignment mechanism 4 improves the positioning accuracy of the glass during the conveying process, reduces processing errors caused by glass position deviation, and improves the quality of deep-processed glass products.

[0028] In operation, after the glass enters the roller conveyor component 1, it decelerates forward. Then, the lifting cylinder 43 operates, driving the crank 44 to rotate. The third connecting rod 45 of the crank 44 rotates, which in turn drives the fourth connecting rod 46 to rotate. This causes the fourth connecting rod 46 to lift the alignment stop. Through the cooperation of the fourth connecting rod 46 and the alignment stop, the glass movement is blocked, keeping it above the belt conveyor mechanism 3. Then, the lifting cylinder 22 operates, driving the power crank component 23 to rotate. The power crank component 23 drives the connecting handle 251 and the first connecting rod 253 to move. The first connecting rod 253 drives the guide shaft to move upward within the linear bearing 26, thereby pushing the belt conveyor mechanism 3 upward and lifting the glass to a certain height. Finally, the belt conveyor mechanism 3 operates to transport the glass out.

[0029] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
