Description

Technical Field

[0001] This invention belongs to the technical field of glass transportation, and specifically relates to a lifting conveyor for transporting double-layered glass. Background Technology

[0002] In the fields of glass deep processing, warehousing and building installation, the transfer of double-glazed glass is a key link connecting various processes. Lifting and conveying devices have become the core equipment for transporting double-glazed glass because they can achieve vertical position adjustment and adapt to equipment docking at different heights.

[0003] Currently, most mainstream double-pane glass lifting and conveying devices employ single- or double-sided driven lifting structures, using hydraulic cylinders, electric push rods, or chain drives to raise and lower the carrying platform. However, in practical applications, double-pane glass is quite heavy and often varies in size and has an uneven center of gravity. When the lifting platform carries the double-pane glass, it is prone to localized stress concentration due to force imbalance. Especially during lifting start-up, stop, and variable speed operation, one end of the platform may tilt significantly due to stress. This tilt not only disrupts the stable placement of the double-pane glass but also reduces the friction between the glass and the platform to offset the gravitational force, easily leading to slippage or even falling of the double-pane glass, seriously threatening production safety and damaging the finished glass product.

[0004] In existing technologies, some solutions attempt to improve stability by increasing the number of platform support points and optimizing the arrangement of drive components. However, such methods can only alleviate the impact of stress to a certain extent and cannot fundamentally eliminate the platform tilting problem caused by uneven stress distribution during lifting. Other solutions use the addition of limiting clamps to restrict glass displacement, but these have the drawbacks of cumbersome clamp operation and poor adaptability, making it difficult to meet the rapid transfer needs of double-layer glass of different sizes.

[0005] Therefore, for the scenario of lifting and conveying double-pane glass, developing a lifting and conveying device that can effectively overcome the effects of stress, avoid tilting of the lifting platform, and prevent glass from slipping is of great significance for improving the safety and efficiency of double-pane glass transportation. Summary of the Invention

[0006] The purpose of this invention is to provide a lifting conveyor for transporting double-layered glass, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a lifting conveyor platform for transporting double-layer glass, comprising a glass lifting and conveying device, wherein the glass lifting and conveying device includes a support frame, a lifting motor, a longitudinal conveying motor, a transverse conveying motor, a mounting frame, several conveying rollers, and two guide rails; the two guide rails are respectively fixedly installed on the left and right sides of the support frame, and the mounting frame is slidably connected to the guide rails; the lifting motor is fixedly installed above the support frame and is connected to the mounting frame via a chain drive; the several conveying rollers are evenly mounted on the mounting frame with bearings; the longitudinal conveying motor is connected to the... A conveyor belt is connected to the transverse conveyor motor, which is connected to several conveyor rollers via gear transmission. Mounting plates are fixed on both the front and rear sides of the mounting frame. A bearing seat is integrally formed on the upper part of the front mounting plate, and an output shaft is rotatably connected inside the bearing seat. One end of the output shaft is movably connected to the conveyor roller. A sliding hole is opened on the upper part of the rear mounting plate, and a sliding rod is slidably connected inside the sliding hole. A bearing seat is integrally formed on the upper end of the sliding rod, and the bottom of the bearing seat is in contact with the upper surface of the rear mounting plate. The other end of the conveyor roller is rotatably connected to the interior of the bearing seat.

[0008] The present invention further explains that the operation steps of the glass lifting and conveying device are as follows: Step S1, the glass lifting and conveying device is started; Step S2, after the double-layer glass is conveyed to the mounting frame by the conveyor belt, the longitudinal position of the double-layer glass is adjusted by the longitudinal conveying motor, and then the lateral position of the double-layer glass is adjusted by the transverse conveying motor; Step S3, the lifting motor is started, and the mounting frame is raised by the chain. After the double-layer glass is raised to the specified height, the operation is stopped, and then the double-layer glass is conveyed left and right or backward by the transverse conveying motor or the longitudinal conveying motor.

[0009] The present invention further describes that a threaded sleeve is fixed on the right side of the bearing seat two, and a turntable is connected to the internal thread of the threaded sleeve. The inner wall of the turntable is evenly provided with several sliding grooves, and an arc-shaped block is slidably connected in each of the several sliding grooves. One end of the conveying roller is provided with a raised strip at the top and bottom, and a sleeve block is slidably connected through the raised strip. The sleeve block is located inside the turntable, and several arc-shaped protrusions are evenly provided on its outer side. The several arc-shaped protrusions are respectively located between the arc-shaped blocks and are engaged with each other.

[0010] The present invention further explains that a push rod is embedded inside the conical hole, and the arc-shaped part of the push rod contacts the maximum inner diameter of the conical hole, that is, the push rod can lift the bearing seat two after it moves. A push plate is integrally formed on the front side of the turntable, and the push rod is located between the bearing seat two and the push plate, and they fit together.

[0011] The present invention further explains that there are several types of bearing housing II, and the difference lies in the taper of the tapered hole, that is, bearing housing II with different tapers is selected according to the number of double-layer glass conveyed each time.

[0012] The present invention further illustrates that the turntable is provided with limiters on both the front and rear sides, and the limiters are in close contact with the sleeve block.

[0013] The present invention further explains that an electromagnetic plate is rotatably connected to the front side of the inner wall of the turntable. The electromagnetic plate generates magnetism when energized, and the magnetic poles are controlled by changing the direction of the current.

[0014] The present invention further explains that the arc-shaped blocks are all made of magnetic material and are axially connected to the inner wall of the turntable.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The glass lifting and conveying equipment used in the present invention realizes the functions of automated conveying and lifting, which greatly improves the transportation efficiency of double-layer glass. At the same time, when conveying double-layer glass to the mounting frame, the operator can add a pad at the bottom of the bearing seat two to avoid the double-layer glass being stuck on one side of the mounting frame due to the misalignment of the conveyor belt and the conveyor roller, thus preventing the automatic conveying of double-layer glass from being interrupted. This forces the glass lifting and conveying equipment to improve the coordination with the conveyor belt and improve the glass transportation efficiency. In addition to manually adding pads, a transverse conveyor motor can be used to rotate the conveyor rollers. This, through a push plate, pushes the top rod against the inner wall of the conical hole, automatically lifting the second bearing seat upwards. This automatically forces the glass lifting and conveying equipment to improve its fit with the conveyor belt, while overcoming the effects of stress. This effectively prevents the double-layered glass from falling during lifting. Furthermore, the number of rotations of the transverse conveyor motor can be controlled according to the number of double-layered glass pieces placed on the conveyor rollers, thereby controlling the upward lifting distance of the second bearing seat to automatically compensate for the effects of stress and further improve the transportation efficiency.

[0017] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-7 The present invention provides a technical solution: a lifting conveyor for transporting double-layer glass, including a glass lifting and conveying device, which includes a support 1, a lifting motor 2, a longitudinal conveying motor 3, a transverse conveying motor 4, a mounting frame 5, several conveying rollers 6, and two guide rails. Two guide rails are fixedly installed on the left and right sides of the bracket 1, and the mounting frame 5 is slidably connected to the guide rails. The lifting motor 2 is fixedly installed above the bracket 1 and is connected to the mounting frame 5 by chain drive. Several conveying rollers 6 are evenly mounted on the mounting frame 5. The longitudinal conveying motor 3 is connected to the conveying belt. The transverse conveying motor 4 is connected to several conveying rollers 6 by gear drive. Mounting plates 7 are fixed on both the front and rear sides of the mounting frame 5. A bearing seat 71 is integrally formed on the upper part of the front mounting plate 7. An output shaft 72 is rotatably connected inside the bearing seat 71. One end of the output shaft 72 is movably connected to the conveying roller 6. A sliding hole is opened on the upper part of the rear mounting plate 7, and a sliding rod 73 is slidably connected inside the sliding hole. A bearing seat 74 is integrally formed on the upper end of the sliding rod 73. The bottom of the bearing seat 74 is attached to the upper surface of the rear mounting plate 7. The other end of the conveying roller 6 is rotatably connected to the inside of the bearing seat 74. The double-pane glass is conveyed onto the mounting frame 5 via a conveyor belt. Then, the horizontal conveyor motor 4 drives the output shaft 72 to rotate the conveyor roller 6 through gear transmission, thereby moving the double-pane glass horizontally left and right. After that, the vertical conveyor motor 3 drives the conveyor belt to move the double-pane glass vertically back and forth. After the position of the double-pane glass is adjusted, the lifting motor 2 starts and drives the mounting frame 5 to move upward through the guide rail via chain transmission, thereby lifting the double-pane glass to the designated position. Then, the horizontal conveyor motor 4 and the vertical conveyor motor 3 drive the double-pane glass to move left and right or backward, automatically conveying the double-pane glass out. This realizes the functions of automated conveying and lifting, which greatly improves the transportation efficiency of double-pane glass. Meanwhile, when conveying double-layered glass to the mounting frame 5, the operator can add a pad to the bottom of the bearing seat 74 to raise the height of the bearing seat 74, so that it is raised upward through the slide rod 73, thereby driving the rear end of the conveyor roller 6 to rise upward, while the front end remains in a fixed position through a movable connection with the output shaft 72. At this time, the rear end of the conveyor roller 6 is raised, which can prevent the double-layered glass from being stuck on one side of the mounting frame 5 due to the misalignment between the conveyor belt and the conveyor roller 6, and prevent the automatic conveying of double-layered glass from being interrupted. This forces the glass lifting and conveying equipment to improve the coordination with the conveyor belt and improve the glass transportation efficiency.

[0019] The operating steps of the glass lifting and conveying equipment are as follows: Step S1, the glass lifting and conveying equipment is started; Step S2: After the double-layered glass is conveyed to the mounting frame 5 by the conveyor belt, the longitudinal position of the double-layered glass is adjusted by the longitudinal conveyor motor 3, and then the lateral position of the double-layered glass is adjusted by the transverse conveyor motor 4. Step S3: The lifting motor 2 starts and drives the mounting frame 5 to rise through the chain. After the double-layer glass is raised to the specified height, the operation stops. Then, the double-layer glass is transported left and right or backward through the horizontal conveyor motor 4 or the vertical conveyor motor 3. The transverse conveyor motor 4 and the longitudinal conveyor motor 3 can not only transport the double-layered glass out to the left, right or backward, but also adjust the position of the double-layered glass before lifting, so that the double-layered glass is located in the center of the mounting frame 5, preventing the double-layered glass from falling during the lifting process, thus ensuring the stability of transportation and protecting the double-layered glass. At the same time, as the double-layered glass is lifted, it may be shaken by the equipment or other factors. At this time, the position of the double-layered glass can be adjusted to keep it in the center position, which greatly improves the stability of transporting the double-layered glass.

[0020] A threaded sleeve 75 is fixed to the right side of the bearing housing 74. A turntable 76 is connected to the internal thread of the threaded sleeve 75. Several grooves are evenly opened on the inner wall of the turntable 76, and arc-shaped blocks 761 are slidably connected in each groove. One end of the conveying roller 6 is provided with protrusions at the top and bottom, and a sleeve block 61 is slidably connected through the protrusions. The sleeve block 61 is located inside the turntable 76, and several arc-shaped protrusions 611 are evenly arranged on the outer side. The arc-shaped protrusions 611 are respectively located between the arc-shaped blocks 761 and are engaged with each other.

[0021] The bottom of the bearing housing 74 is provided with a tapered hole 741. A push rod 742 is embedded inside the tapered hole 741, and the arc-shaped part of the push rod 742 contacts the maximum inner diameter of the tapered hole 741. That is, the push rod 742 can lift the bearing housing 74 after it moves. The front side of the turntable 76 is integrally formed with a push plate 762. The push rod 742 is located between the bearing housing 74 and the push plate 762 and fits against each other. When lifting double-pane glass, if there are many double-pane glass panes placed on the conveyor roller 6 and they are heavy, the rear end of the mounting frame 5 will be subjected to greater force, resulting in downward stress on the rear end of the mounting frame 5 as a whole. At this time, the conveyor roller 6 will rotate through the transverse transmission motor 4. During the rotation of the conveyor roller 6, the sleeve block 61 will be engaged by the protrusion, thereby driving the sleeve block 61 to rotate. The sleeve block 61 will drive the arc-shaped protrusion 611 to rotate around its center and press against the arc-shaped block 761, causing the arc-shaped block 761 to be subjected to force, which will drive the turntable 76 to rotate. The turntable 76 will rotate and move backward inside the screw sleeve 75 through the threaded transmission, thereby driving the push plate 762 to move backward. The push plate 762 will push the top rod 742 to press against the inner wall of the conical hole 741, thereby automatically lifting the bearing seat 74 upward to overcome the influence of stress and fully prevent the double-pane glass from falling during lifting. At the same time, the number of rotations of the transverse conveyor motor 4 can be controlled according to the number of double-layered glass placed on the conveyor roller 6, thereby controlling the upward lifting distance of the bearing seat 74 to automatically compensate for the impact of stress and further improve the transportation effect.

[0022] There are several models of bearing housing 74, and the difference lies in the taper of the tapered hole 741. That is, different tapers of bearing housing 74 are selected according to the number of double-layer glass conveyed each time. If the number of double-pane glass panes lifted each time is different, and the taper of the tapered hole 741 cannot adapt to the stress generated under the weight of the glass, then the bearing housing 74 can be replaced. It has a wide range of applications and can be used to lift double-pane glass panes of any weight. Furthermore, the structure used to overcome the stress caused by the weight of the glass is simple, the manufacturing cost is low, and it is also easy to disassemble and assemble. Subsequent maintenance is also relatively convenient, which reduces labor costs.

[0023] Limiters are provided on both the front and rear sides of the turntable 76, and the limiters are in close contact with the sleeve block 61. By limiting the turntable 76, the sleeve 61 can be squeezed by the limit when it rotates, so that the sleeve 61 can move automatically with the turntable 76. This greatly reduces the restriction on the lifting bearing seat 74 and increases the lifting stroke, so as to force the double glass to maintain full balance when it is lifted and prevent it from sliding and falling.

[0024] An electromagnetic plate 77 is rotatably connected to the front side of the inner wall of the turntable 76. When the electromagnetic plate 77 is energized, it generates magnetism and controls the magnetic poles by changing the direction of the current.

[0025] The arc-shaped blocks 761 are all made of magnetic material and are axially connected to the inner wall of the turntable 76; When the bearing housing 2 74 is raised to overcome stress, i.e., when the lifting motor 2 is running, the magnetic poles generated by the energized electromagnetic plate 77 are opposite to those of the arc-shaped block 761, thus attracting the arc-shaped block 761. This allows the arc-shaped protrusion 611 to smoothly press against the arc-shaped block 761, ensuring the smooth progress of the stress-overcoming process. At the same time, as the transverse conveyor motor 4 rotates, the double-layered glass is conveyed to the edge via the conveyor roller 6. After the stress-overcoming work is completed, i.e., the lifting is finished, the lifting motor 2 stops running, and the transverse conveyor motor 4 starts running. To prevent the glass from falling, the current direction of the electromagnetic plate 77 is changed. When the magnetic poles of the electromagnetic plate 77 and the arc-shaped block 761 are reversed, a magnetic repulsion force is generated, which pushes the arc-shaped block 761 to slide in the groove and through the shaft, improving the movement stability of the arc-shaped block 761. At this time, the transverse conveyor motor 4 rotates in the opposite direction, pulling the double-layer glass back through the conveyor roller 6. Meanwhile, the arc-shaped protrusion 611 cannot contact the arc-shaped block 761 when it rotates, so that the double-layer glass can be reset smoothly and avoid affecting stress relief. After the transportation is completed, the magnetic poles of the electromagnetic plate 77 are reversed again with those of the arc-shaped block 761, so that the arc-shaped block 761 is reset, and the screw sleeve 75 is reset to facilitate the next stress relief.
