Description

Technical Field

[0001] The invention relates to the technical field of technical glass manufacturing, and in particular to a torque-balanced glass flipping device. Background Art

[0002] In the production of float glass or architectural glass deep processing, there are often some products with larger panel sizes and heavier weight. These products require automatic equipment for loading and unloading upper and lower glass sheets online, such as automatic stacking machines that flip lower sheets. When stacking lower sheets, the maximum height can meet 3660mm and the length can meet more than 4000mm. At present, the longest length of float glass in the industry can reach 13 meters. When these heavy and large panels of glass are taken out by automatic stacking machines that flip lower sheets, the flipping torque that needs to be overcome is very large.

[0003] In mechanical automation design, a reduction motor device is usually used to output the corresponding torque, and the output shaft is used to drive the flipping mechanism to realize the flipping function of the mechanism; when the weight of the product to be flipped is larger and the distance from the center of gravity is longer, the torque required for flipping is larger, and the required motor power and speed ratio of the reducer are larger. The larger the motor power, the more power consumption, which is not energy-saving; the larger the speed ratio of the reducer, the heavier the size and weight of the reducer body. The large and heavy reducer occupies the effective installation space of the equipment. When the installation space of the equipment is limited, especially the total height is limited, the effective passage of the glass sheet must be ensured above without hitting the glass, and a certain distance from the ground must be ensured below. This often causes some contradictions in large-scale automation equipment. Some achieve this goal by raising all conveying elevations, and some achieve this goal by digging pits and sinking. These methods are either inconvenient to produce or have high overall costs. Summary of the invention

[0004] The purpose of the present invention is to provide a torque-balanced glass flipping device, aiming to solve the problem that the existing device is inconvenient to produce or has high cost in order to meet the torque.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A torque-balanced glass flipping device comprises a support seat, a reduction drive mechanism arranged on the support seat, a suction cup frame for adsorbing glass and hinged to the support seat at one end, an output shaft arranged at the output end of the reduction drive mechanism, and a crank mechanism hinged to the suction cup frame at one end and fixedly connected to the output shaft at the other end. The torque-balanced glass flipping device also comprises a torque device for assisting the output shaft to rotate around the axis, the torque device comprises a rotating mechanism arranged on the output shaft and a driving mechanism hinged to the rotating mechanism and driving the rotating mechanism to rotate around the axis of the output shaft in the assisting direction.

[0007] Beneficial effects of the present invention: The present invention provides torque for the output shaft by setting a torque device to assist the output shaft in rotating, so that the torque generated by the reduction drive mechanism and the torque generated by the rotation mechanism driven by the drive mechanism form a combined torque to jointly drive the flipping device to work. A rotation mechanism is set on the output shaft, and the drive mechanism is hinged with the rotation mechanism. The rotation mechanism rotates in the assisting direction according to the driving force provided by the drive mechanism, so that the rotation mechanism can assist the output shaft in rotating in the assisting direction to generate torque in the same direction as the reduction drive mechanism, thereby providing torque to the output shaft.

[0008] In one embodiment, the rotating mechanism is a chain plate sleeved on the output shaft, the driving mechanism is hinged to the chain plate through a chain, and the chain plate rotates around the axis of the output shaft in the power-assisting direction under the traction of the chain.

[0009] By adopting the above technical solution, the chain plate and the driving mechanism are connected by a chain hinge, and the driving mechanism pulls the chain to rotate the chain plate in the power-assisting direction, thereby causing the chain plate power-assisting output shaft to rotate in the power-assisting direction to provide the torque required for turning the glass.

[0010] In one embodiment, the circumferential end side of the chain plate is recessed inwardly to form a groove, and the chain is accommodated in the groove.

[0011] By adopting the above technical solution, the groove is used to accommodate the chain, so that the chain is arranged along the outer circumference of the chain plate. When the chain is pulled by the driving mechanism, the force arm formed by the chain dragging the chain plate to rotate is the radius of the chain plate, that is, the force arm formed in this way is the longest and the assist torque formed is the largest.

[0012] In one embodiment, the cross section of the chain disk along the radial direction is semicircular, and the movement stroke of the chain is less than half the circumference of the chain disk.

[0013] By adopting the above technical solution, since the working stroke of the chain disc is only semicircular, the semicircular chain disc fully utilizes the material and avoids unnecessary waste. In the working process of flipping the glass, as the suction cup frame rotates around the hinge between it and the bracket seat, when the overall center of gravity of the suction cup frame transporting the glass rotates from one side of the hinge to the other side of the hinge, the torque required for flipping the glass is reversed, that is, there is no need for the drive mechanism to continue to pull the chain in the power-assisting direction to provide torque. At this time, adding torque in the power-assisting direction will cause uncontrollable flipping; at the same time, the torque required when the suction cup frame is started horizontally is the largest, that is, when the overall center of gravity of the suction cup frame transporting the glass rotates from one side of the hinge to the other side of the hinge, it is only necessary to reduce the torque provided by the drive mechanism itself, and there is no need for the torque device to continue to operate to provide power-assisting torque; therefore, by ensuring that the stroke of the chain movement is less than half the circumference of the chain disc, the torque device only provides power-assisting torque when the overall center of gravity of the suction cup frame transporting the glass has not been transferred to the other side of the hinge.

[0014] In one embodiment, the rotating mechanism includes a rotating tube sleeved on the output shaft and a chain with one end wound around the rotating tube. The driving mechanism is connected to the other end of the chain. The rotating tube assists the output shaft in rotating when the driving motor pulls the chain.

[0015] By adopting the above technical solution, the driving mechanism is used to pull one end of the chain, so that the other end wound around the rotating tube pulls the rotating tube to rotate, thereby assisting the output shaft to rotate and provide torque.

[0016] In one embodiment, the rotating tube includes a tube body sleeved on the output shaft, and the cross section of the tube body along the radial direction is elliptical.

[0017] By adopting the above technical solution, a tube body with an elliptical cross-section in the radial direction is used as a rotating mechanism. When the driving mechanism pulls the chain, one end of the chain pulls the tube body to rotate to assist the output shaft in rotating to provide torque. The elliptical structure causes the force arm to continuously change when the chain pulls the tube body, thereby corresponding to the changes in different torque requirements when the suction cup frame adsorbs and flips the glass and moves.

[0018] In one embodiment, the rotating mechanism is a plurality of support columns, each support column is spaced around the central axis of the output shaft and circumferentially arranged outside the output shaft, and the driving mechanism is hinged to the end of one of the support columns through a chain.

[0019] By adopting the above technical solution, the driving mechanism is used to pull one end of the chain, so that the chain is pulled by the hinged support column and the other support columns to jointly pull the power output shaft to rotate to provide torque.

[0020] In one embodiment, the length of each support column increases step by step along the power assisting direction.

[0021] By adopting the above technical solution, the support column is used as a rotating mechanism. When the driving mechanism pulls the chain to rotate, the chain uses the longest support column at the end as a force arm to pull the power-assisting output shaft to rotate when it is in the initial position. When the output shaft rotates toward the power-assisting direction, the length of the support column serving as the force arm becomes smaller and smaller, that is, the torque provided by the driving mechanism through the chain and the support column becomes smaller and smaller, corresponding to the reduction in the torque demand of the suction cup frame during the flipping of the lower sheet.

[0022] In one embodiment, the reduction drive mechanism has two symmetrically arranged output ends, the two output ends of the reduction drive mechanism are respectively provided with output shafts, and the number of the torque devices is two, and they respectively correspond to the output shafts.

[0023] By adopting the above technical solution, the torque is provided by using the torque devices symmetrically arranged on the output shafts on both sides of the output end of the high-speed driving mechanism, so that the force on the output shaft is balanced.

[0024] In one embodiment, the driving mechanism is disposed on one side of the rotating mechanism, and the driving mechanism is fixed to the bracket seat.

[0025] By adopting the above technical solution, the driving mechanism is arranged on one side of the rotating mechanism, and the driving mechanism is used to provide traction force to the rotating mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Please refer to Figures 1 to 4 , this embodiment provides a torque-balanced glass flipping device, including a support seat 10, a reduction drive mechanism 20 disposed on the support seat 10, a suction cup frame 30 for adsorbing glass and hinged to the support seat 10 at one end, an output shaft 21 disposed at the output end of the reduction drive mechanism 20, and a crank mechanism 40 hinged to the suction cup frame 30 at one end and fixedly connected to the output shaft 21 at the other end. By rotating the output shaft 21 of the reduction drive mechanism 20, the suction cup frame 30 rotates through the crank mechanism 40 to move the glass to a specified position. The torque-balanced glass flipping device also includes a torque device 50 for assisting the output shaft 21 to rotate around the axis. The torque device 50 includes a rotating mechanism 51 disposed on the output shaft 21, and a driving mechanism 52 hinged to the rotating mechanism 51 and driving the rotating mechanism 51 to rotate around the axis of the output shaft 21 in the assisting direction. Among them, the driving mechanism 52 can adopt a telescopic mechanism with a piston such as a pneumatic cylinder or a hydraulic cylinder. In this embodiment, a pneumatic cylinder is used as the driving mechanism 52. And Figure 2 The arrow direction in is the power assist direction, which is also the same as the rotation direction of the output shaft 21 to lift the suction cup frame 30.

[0042] The torque device 50 is provided to assist the output shaft 21 to rotate, and torque is provided to the output shaft 21, so that the torque generated by the reduction drive mechanism 20 and the torque generated by the rotation mechanism 51 driven by the drive mechanism 52 form a combined torque to jointly drive the lower sheet flipping device to work. The rotation mechanism 51 is provided on the output shaft 21, and the drive mechanism 52 is hinged with the rotation mechanism 51. The rotation mechanism 51 rotates in the assisting direction according to the driving force provided by the drive mechanism 52, so that the rotation mechanism 51 can assist the output shaft 21 to rotate in the assisting direction, so as to generate torque in the same direction as the reduction drive mechanism 20, and play the effect of providing torque to the output shaft 21.

[0043] When the torque-balanced glass flipping device of the present application is working, the output shaft 21 is rotated by starting the reduction drive mechanism 20, and the suction cup frame 30 is driven to rotate around the hinged support seat 10 through the crank mechanism 40 to start flipping the glass. Since the gravity of the glass is greater, the torque to overcome the flipping is also greater. At this time, the pneumatic cylinder is started to shrink the piston of the pneumatic cylinder, and then the piston pulls the chain 53 to pull the rotating mechanism 51 to rotate, so that the rotating mechanism 51 assists the output shaft 21 to rotate, thereby generating a torque in the same direction as the reduction drive mechanism 20. The torque formed by the torque device 50 and the torque generated by the reduction drive motor 20 form a combined torque to jointly provide a torque to overcome the flipping, so as to meet the torque required for flipping the glass.

[0044] Embodiment 1

[0045] Please refer to Figures 1 to 4 In this embodiment, the rotating mechanism 51 is a chain plate 511a sleeved on the output shaft 21. The piston of the pneumatic cylinder is hinged to the chain plate 511a through a chain 53. When the piston of the pneumatic cylinder contracts, the piston pulls the chain 53 to move in the power-assisting direction, so that the chain 53 pulls the chain plate 511a to rotate in the power-assisting direction, thereby causing the chain plate 511a to rotate the power-assisting output shaft 21 in the power-assisting direction to provide the torque required for operating the glass.

[0046] Specifically, the circumferential end side of the chain plate 511a is recessed inward to form a groove 512, and the chain 53 is accommodated in the groove 512. The groove 512 is used to accommodate the chain 53, so that the chain 53 is arranged along the circumference direction of the chain plate 511. When the piston of the pneumatic cylinder is contracted to pull the chain 53, the force arm formed by the chain 53 dragging the chain plate 511a to rotate is the radius of the chain plate 511a, that is, the force arm formed is the longest, and the maximum assist torque is obtained.

[0047] Optionally, the cross-section of the chain plate 511a along the radial direction is semicircular. Since the working stroke of the chain plate 511a is only semicircular, the semicircular chain plate 511a can fully utilize the material and avoid unnecessary waste. During the glass flipping process, as the suction cup frame 30 rotates around the hinge with the bracket seat 10, when the overall center of gravity of the glass transported by the suction cup frame 30 rotates from one side of the hinge to the other side of the hinge, the torque required for flipping the glass is reversed, that is, there is no need for the drive mechanism 52 to continue to pull the chain 53 in the assisting direction to provide torque. At this time, adding torque in the assisting direction will cause uncontrollable flipping. At the same time, the torque required when the suction cup frame 30 is started horizontally is the largest, that is, when the overall center of gravity of the glass transported by the suction cup frame 30 rotates from one side of the hinge to the other side of the hinge, it is only necessary to slow down the torque provided by the drive mechanism 20 itself, and there is no need for the torque device 50 to continue to operate to provide assisting torque. Therefore, by ensuring that the movement stroke of the chain 53 is less than the half circumference of the chain plate 511a, the torque device 50 only provides assisting torque when the overall center of gravity of the glass transported by the suction cup frame 30 has not been transferred to the other side of the hinge.

[0048] Embodiment 2

[0049] Please refer to Figure 5 and Figure 6 In this embodiment, the rotating mechanism 51 is a rotating tube 511b sleeved on the output shaft 21 and a chain 53 with one end wound around the rotating tube. The driving mechanism 52 is connected to the other end of the chain 53. The rotating tube 511b assists the output shaft 21 to rotate under the pulling of the chain 53 by the driving mechanism 52. The driving mechanism 52 pulls one end of the chain 53 so that the other end wound around the rotating tube 511b pulls the rotating tube 511b to rotate, thereby assisting the output shaft 21 to rotate and provide torque. The driving mechanism 52 in this embodiment adopts a pneumatic cylinder.

[0050] Specifically, the rotating tube 511b includes a tube body sleeved on the output shaft, and the cross section of the tube body along the radial direction is elliptical. The tube body with an elliptical cross section in the radial direction is used as the rotating mechanism 51. When the driving mechanism 52 pulls the chain 53, one end of the chain 53 pulls the tube body to rotate to assist the output shaft 21 to rotate to provide torque. The elliptical structure makes the force arm of the chain 53 constantly change when pulling the tube body, thereby corresponding to the change of different torque requirements when the suction cup frame 30 absorbs and moves the flip glass.

[0051] Please pay attention to Figure 5In the initial state, one end of the chain 53 is connected to the piston of the pneumatic cylinder, and the chain 53 is tangent to the long axis of the elliptical tube body, that is, the torque required to flip the glass in the initial state is relatively large. At this time, when the piston of the pneumatic cylinder contracts to pull the chain 53, the chain 53 rotates around the center of the elliptical tube body, that is, the long axis of the elliptical tube body is the lever arm at this time. Under the premise that a large torque is required for flipping the glass at this time, a longer lever arm is used to provide a larger torque. As the flipping continues, the torque required for flipping gradually decreases. At this time, the elliptical tube body rotates continuously, that is, the tangent point of the chain 53 and the elliptical tube body continuously moves from the long axis of the tube body to the short axis, that is, the length of the lever arm gradually decreases, so that when the pneumatic cylinder pulls the chain 53, the torque provided to the output shaft 21 is also gradually reduced, and the torque provided by the torque device 50 can meet the torque requirement of flipping the glass.

[0052] Embodiment 3

[0053] Please refer to Figure 7 and Figure 8 In this embodiment, the rotating mechanism 51 is a plurality of supporting columns 511c, each supporting column 511c is spaced around the central axis of the output shaft 21 and arranged circumferentially on the outside of the output shaft 21, and the driving mechanism 52 is hinged to the end of the first supporting column 511c through a chain 53. The driving mechanism 52 in this embodiment adopts a pneumatic cylinder. The piston of the pneumatic cylinder is contracted to pull one end of the chain 53, so that the chain 53 pulls the power output shaft 21 to rotate through the hinged supporting column 511c and the other supporting columns 511c to provide torque.

[0054] The length of each support column 511c increases step by step along the power-assisting direction. The support column 511c is used as the rotating mechanism 51. When the driving mechanism 52 pulls the chain 53 to rotate, the chain 53 uses the longest support column 511c at the end as a lever arm to pull the power-assisting output shaft 21 to rotate at the initial position. At this time, the chain 53 is wrapped around the top of other support columns 511c. When the output shaft 53 rotates toward the power-assisting direction, the length of the support column 511c as the lever arm becomes smaller and smaller, that is, the torque provided by the driving mechanism 52 through the chain 53 and the support column 511c becomes smaller and smaller, corresponding to the reduction of the torque demand of the suction cup frame 30 during the flipping of the lower sheet.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
