[0023] Reference Figure 1-5 The utility model proposes an automatic reversing device for glass sheets, comprising: a frame 1, a plurality of conveying rollers 2 installed in parallel on the frame 1, a main driving mechanism installed on the frame 1 to drive all the conveying rollers 2 to rotate in the same direction, and a lifting and rotating mechanism, wherein: each conveying roller 2 is fixed with a plurality of rollers 3 arranged at intervals along its length direction, and the lifting and rotating mechanism comprises a lifting platform 4, a rotating platform 5, and a first driving mechanism and a second driving mechanism.

[0024] The lifting platform 4 is located below the surface where the conveying rollers 2 are located and is driven by the first driving mechanism to rise and fall. The thickness of the rotating platform 5 is less than the radius of the roller 3, and the rotating platform 5 is a grid-shaped plate formed by staggered multiple transverse rods and multiple longitudinal rods; the rotating platform 5 is located above the surface where the conveying rollers 2 are located, and the rotating platform 5 has a first position state and a second position state obtained by rotating 90° from the first position state, and when the rotating platform 5 is in the first position state, each transverse rod in the rotating platform 5 is located in the gap between each conveying roller 2, and each longitudinal rod in the rotating platform 5 is located in the gap between each roller 3; when the rotating platform 5 is in the second position state, each transverse rod in the rotating platform 5 is located in the gap between each roller 3, and each longitudinal rod in the rotating platform 5 is located in the gap between each conveying roller 2.

[0025] The second driving mechanism is installed on the lifting platform 4 so that it can be lifted and lowered along with the lifting platform 4. The second driving mechanism includes a driving shaft 6 and a power component 7 for driving the driving shaft 6 to rotate. The driving shaft 6 is vertically arranged below the center of the rotating platform 5, and its top end passes through the gap between the conveying rollers 2 and is fixed to the rotating platform 5, so that the rotating platform 5 can be lifted and lowered along with the lifting platform 4, and can also rotate along with the rotation of the driving shaft 6.

[0026] During operation, when the direction of the glass sheet is correct, the rotating table 5 sinks below the top surface of the roller 3, so that the glass sheet is transmitted forward with the rotation of the roller 3. When the direction of the glass sheet is wrong, when the glass sheet enters the surface area where the rotating table 5 is located, the first driving mechanism drives the lifting platform 4 to move upward to push the rotating table 5 to the top of the roller 3, and then the glass sheet originally supported by the roller 3 falls onto the rotating table 5. At this time, the second driving mechanism drives the rotating table 5 to rotate 90°, and then falls back to the bottom of the roller 3, so that the glass sheet falls back on the roller 3 and continues to be transmitted forward.

[0027] In a further embodiment, a roller shaft 8 parallel to the conveying roller 2 is provided on the frame 1 and at one end located in the conveying direction of the conveying roller 2, and both ends of the roller shaft 8 are rotatably connected to the frame 1. The roller shaft 8 is provided with a connecting handle 9 fixed to the frame 1 at one end, and a plurality of brackets arranged at intervals along the length direction thereof and fixed to the frame 1 and a rubber block 10 mounted on the bracket, and all the rubber blocks 10 are located above the roller shaft 8, and the other end of the connecting handle 9 is located on the side of the rotating shaft away from the conveying roller 2; a cylinder A11 is provided below the connecting handle 9, and the cylinder A11 is installed on the frame 1, and the extended end of the cylinder A11 is movably connected to the other end of the connecting handle 9. During operation, when the glass sheet enters the area where the rubber block 10 is located, the cylinder A11 is extended and retracted to pull the roller shaft 8 and the conveying roller 2 to rotate in the same direction through the connecting handle 9, and then drive the rubber block 10 to swing in the direction away from the conveying roller 2, thereby pushing the glass sheet out of the device to move to the next station.

[0028] In a further embodiment, the lower end of the driving shaft 6 is rotatably assembled with the lifting platform 4 to increase the supporting force of the driving shaft 6, thereby ensuring the stability of the support for the rotating platform 5. The power component 7 includes a motor fixed on the lifting platform 4, a driving gear driven to rotate by the motor, and a driven gear installed on the driving shaft 6 and meshing with the driving gear. The motor drives the driven gear to rotate through the driving gear, thereby driving the rotating platform 5 to rotate.

[0029] Furthermore, a flange is provided at the center of the rotating platform 5, the driving shaft 6 is a cylindrical tube structure, and a flange is also provided at the top of the driving shaft 6, and the flange at the top of the driving shaft 6 is attached to the flange on the rotating platform 5 and fastened by bolts. The cylindrical tube driving shaft 6 structure can reduce its own gravity while ensuring the supporting force, and the flange connection method is convenient for installation.

[0030] In a further embodiment, the roller 3 is a rubber wheel or the rotating surface of the roller 3 is coated with a rubber layer, so that the roller 3 is in soft contact with the glass sheet, thereby avoiding damage to the glass.

[0031] In a further embodiment, the lifting platform 4 can be movably installed on the frame 1 up and down, and a long waist hole 12 in a horizontal state is provided on the side of the lifting platform 4; the first driving mechanism includes a rotating shaft 13, an active crank, a driven crank 14 and a cylinder B15; the rotating shaft 13 is located on one side of the lifting platform 4 and is rotatably installed on the frame 1, and the horizontal height of the rotating shaft 13 is lower than the horizontal height of the long waist hole 12; one end of the driven crank 14 is fixed to the rotating shaft 13, and the other end of the driven crank 14 is provided with a roller, and the roller is located in the long waist hole 12; one end of the active crank is fixed to the rotating shaft 13; the cylinder B15 is located on one side of the rotating shaft 13, and the bottom of the cylinder B15 is movably connected to the frame 1, and the top of the cylinder B15 is connected to the other end of the active crank through a pin shaft parallel to the rotating shaft 13. During operation, the cylinder B15 drives the rotating shaft 13 to rotate by telescoping, and the rotating shaft 13 drives the driven crank 14 to swing. Since the roller at its end is in the long waist hole 12 of the lifting platform 4, it then pushes the lifting platform 4 to rise and fall. This lifting method can effectively reduce the overall height of the entire device.

[0032] Furthermore, two rotating shafts 13 are provided, and the two rotating shafts 13 are arranged on both sides of the lifting platform 4. Each rotating shaft 13 is provided with a corresponding active crank and a driven crank 14, and the active cranks on the two rotating shafts 13 are connected by a connecting rod to form a linkage, and the driven cranks 14 on the two rotating shafts 13 have corresponding long waist holes 12. That is, the two rotating shafts 13 are driven by the same motor to achieve synchronous and unidirectional rotation. This design can effectively increase the stability of the upgrading platform lifting.

[0033] Furthermore, two driven cranks 14 are arranged on the same rotating shaft 13, and the two driven cranks 14 are arranged on both sides of the driving crank on the rotating shaft 13, and the driving crank is located at the center of the rotating shaft 13. That is, the two rotating shafts 13 have four driven cranks 14, and the lifting platform 4 has four long waist holes 12 corresponding to the driven cranks 14, which can further increase the lifting stability of the lifting platform 4.

[0034] As can be seen from the above, in the utility model, the roller 3 is arranged in the length direction of the conveying roller 2, the lifting platform 4 is arranged below the conveying roller 2, the rotating platform 5 is arranged above the conveying roller 2, and the thickness of the rotating platform 5 is smaller than the radius of the roller 3, each transverse rod in the rotating platform 5 is located in the gap between each conveying roller 2, each longitudinal rod in the rotating platform 5 is located in the gap between each roller 3, and when the rotating platform 5 rotates 90°, each transverse rod thereof is switched to the gap between each roller 3, and each longitudinal rod in the rotating platform 5 is switched to the gap between each conveying roller 2. At the same time, the second driving mechanism is installed on the lifting platform 4, and the driving shaft 6 in the second driving mechanism is vertically arranged below the center of the rotating platform 5, and its top end passes through the gap between the conveying rollers 2 and is fixed to the rotating platform 5. During normal transmission, the rotating table 5 sinks below the top surface of the roller 3, so that the glass piece is transmitted forward with the rotation of the roller 3. When the direction of the glass piece is wrong, when the glass piece enters the surface area where the rotating table 5 is located, the first driving mechanism drives the lifting platform 4 to move upward to push the rotating table 5 to the top of the roller 3, and then the glass piece originally supported by the roller 3 falls onto the rotating table 5. At this time, the second driving mechanism drives the rotating table 5 to rotate 90°, and then falls back to the bottom of the roller 3, so that the glass piece falls back on the roller 3 and continues to be transmitted forward, thereby realizing the operation during the assembly line and greatly improving the work efficiency.
