Description

Technical Field

[0001] This invention relates to the field of glass conveying technology, specifically to a dual-speed lifting and conveying system for loading and unloading glass. Background Technology

[0002] In the field of glass deep processing, the transmission system connecting the front-end printer and the back-end dryer needs to balance speed matching, efficiency control, and material inspection and unloading functions. However, existing technologies have the following shortcomings in achieving these functions:

[0003] Firstly, existing technologies struggle to balance efficiency and quality in terms of matching transmission speeds and ensuring stable handover. While solutions exist that use a single conveyor belt with mid-transmission speed adjustments to accommodate both the front-end printer and the rear-end dryer, this method can only transport one piece of glass at a time, failing to effectively control the glass spacing and resulting in low production efficiency. To improve efficiency, two sets of rollers with identical heights are often used for direct connection. However, because the glass simultaneously contacts the two sets of rollers with different speeds at the moment of handover, the difference in linear velocity leads to severe relative sliding friction, easily scratching the glass surface or causing breakage. Although some solutions attempt electronic synchronization control, this increases cost and complexity, and it is difficult to completely eliminate the risk of mechanical interference.

[0004] Secondly, besides the handover challenges on the transmission line, the side unloading function downstream of the transmission line also has significant shortcomings. To meet the needs of manual visual inspection and side unloading during the transmission process, existing side unloading equipment typically relies on multiple independent power sources and complex linkage mechanisms to achieve the tilting of the unloading plate and the reversal of the wheels. This structure is not only bulky and costly, but also difficult to control in terms of synchronized operation, making it prone to interference or jamming.

[0005] Therefore, it is necessary to provide a glass dual-speed lifting and conveying loading and unloading system to solve the above problems. Summary of the Invention

[0006] To address the aforementioned problems, the present invention provides the following technical solution: a dual-speed lifting and conveying system for glass, comprising: a first conveying roller group for conveying glass at a first conveying speed; a second conveying roller group disposed on one side of the first conveying roller group for conveying glass from the first conveying roller group at a second conveying speed; and a transition roller group disposed between the first and second conveying roller groups for supporting the transfer of glass between the first and second conveying roller groups; the first conveying roller group includes at least a first roller body, the second conveying roller group includes at least a second roller body, the upper surfaces of the first and second roller bodies are flush, and the transition roller group includes at least a transition roller, the upper surface of which is higher than the upper surface of the first roller body, so that during the transfer of glass from the first conveying roller group to the second conveying roller group, the glass can contact the transition roller group and one of the first and second conveying roller groups at any time.

[0007] Preferably, the transition roller assembly further includes two roller seat assemblies for rotatably connecting the transition roller. Each roller seat assembly includes: a mounting plate with a mounting chamber fixed on it; a lifting rod with one end located in the mounting chamber and the other end sliding out of the mounting chamber; a lifter fixed below the mounting chamber with its output end extending into the mounting chamber and connected to the lifting rod; and a roller seat fixed to the top of the lifting rod for rotatably connecting the transition roller.

[0008] Preferably, the installation chamber has four locking arc plates arranged in a circumferential array. The locking arc plates are hinged to the inner surface of the installation chamber via a hinge frame, and an elastic element is attached to the inner surface of the locking arc plates. Locking posts are threaded to both sides of the installation chamber. A universal hinge ball is hinged to the center of each locking post. Two hinge rods are hinged to the universal hinge ball, and the ends of the hinge rods away from the locking posts are correspondingly hinged to the locking arc plates.

[0009] Preferably, the outer surface of the lifting rod is provided with a plurality of spikes.

[0010] Preferably, the upper surface of the transition roller is 5mm-20mm higher than the upper surface of the first roller.

[0011] Preferably, the distance between the transition roller and the adjacent first roller body is 80mm-200mm; the distance between the transition roller and the adjacent second roller body is 80mm-200mm.

[0012] Preferably, the second conveyor roller assembly also has a notch to form an accommodating space for installing a side unloading assembly, the side unloading assembly comprising: an unloading plate, one end of which is hinged to the second conveyor roller assembly; a plurality of wheel seats fixed to the unloading plate, and a rotating seat rotatably mounted on the wheel seats, with a return torsion spring disposed between the rotating seat and the wheel seats; a wheel body rotatably mounted on the rotating seat, and in the initial state, the central axis of the wheel body is parallel to the central axis of the second roller body, and the upper surface of the wheel body is flush with the second roller body; a telescopic cylinder hinged between the unloading plate and the second conveyor roller assembly; the center of gravity of the rotating seat and the wheel body mounted thereon constitutes a component offset from the rotation center axis of the rotating seat.

[0013] Preferably, a guide assembly is also provided on one side of the second transfer roller group. The guide assembly includes a first guide plate, which is arranged perpendicular to the transfer direction of the second transfer roller group.

[0014] Preferably, the first guide plate has a clearance groove on the side near the second transmission roller group; the guide assembly further includes: a rotating shaft, rotatably mounted on the first guide plate; a second guide plate, fixed on the rotating shaft and located in the clearance groove; and an adjusting cylinder, hinged between the rotating shaft and the first guide plate.

[0015] Compared with the prior art, the present invention provides a glass dual-speed lifting and conveying loading and unloading system, which has the following beneficial effects:

[0016] In the process of transferring glass from the first transfer roller group to the second transfer roller group, the glass contacts the transition roller group and one of the first and second transfer roller groups at any time. This effectively avoids relative sliding friction caused by the inconsistent linear speeds of the front and rear roller groups, eliminates motion interference caused by speed differences, and maximizes the protection of the glass surface quality, preventing scratches and breakage. At the same time, compared with a complex synchronous control system, this structure achieves its function solely through mechanical geometric positional relationships, significantly reducing manufacturing costs and control difficulty, and improving the operational stability of the system.

[0017] This invention drives the locking pin to drive the hinge rod, which in turn causes the locking arc plate to deflect. Combined with the spiked structure on the surface of the lifting rod and the high-pressure engagement of the elastic element, a rigid connection with both high-strength static friction and mechanical interlocking is formed, preventing the transition roller group from sinking slightly under long-term heavy load conditions.

[0018] This invention utilizes the gravitational torque generated by the misalignment of the center of gravity and rotation center of the rotating seat and wheel assembly. A single telescopic cylinder can simultaneously drive the material plate to deflect and force the wheel to rotate automatically by 90 degrees, completing the state switch from longitudinal support to lateral guidance. No additional power source or complex linkage mechanism is required, which greatly simplifies the mechanical structure and control logic. While reducing the failure rate, it ensures a smooth transition and guidance of the glass during the material feeding process. Attached Figure Description

[0026] In the embodiments of the present invention, please refer to Figures 1-6A dual-speed lifting and conveying system for glass is provided, comprising: a first conveying roller group 1 for conveying glass at a first conveying speed; a second conveying roller group 3 disposed on one side of the first conveying roller group 1 for conveying glass from the first conveying roller group 1 at a second conveying speed; and a transition roller group 2 disposed between the first conveying roller group 1 and the second conveying roller group 3 for supporting the transfer of glass between the first conveying roller group 1 and the second conveying roller group 3. The first conveying roller group 1 includes at least a first roller body, and the second conveying roller group 3 includes at least a second roller body. The upper surfaces of the first roller body and the second roller body are flush. The transition roller group 2 includes at least a transition roller 27, the upper surface of which is higher than the upper surface of the first roller body, so that during the transfer of glass from the first conveying roller group 1 to the second conveying roller group 3, the glass can contact the transition roller group 2 and one of the first conveying roller group 1 and the second conveying roller group 3 at any time.

[0027] In practice, the first conveyor roller group 1 operates at a first conveying speed, transporting the glass forward. When the glass reaches the end of the first conveyor roller group 1 and enters the transition area, the upper surface of the transition roller 27 in the transition roller group 2, located between the first and second conveyor roller groups 1 and 3, is configured to be higher than the upper surface of the first roller body of the first conveyor roller group 1. Upon contact with the transition roller 27, the front end of the glass undergoes an upward movement. During this process, the glass gradually detaches from the support of the first conveyor roller group 1. Then, the glass enters the area of ​​the second conveyor roller group 3. Since the upper surface of the second roller body of the second conveyor roller group 3 is flush with the first roller body (i.e., lower than the upper surface of the transition roller 27), the glass naturally descends during its movement, smoothly falling back and adhering to the second conveyor roller group 3, and begins to be transported at the second conveying speed.

[0028] It should be explained that in a glass conveyor line, the first conveying speed and the second conveying speed are often inconsistent. If the glass simultaneously contacts two sets of rollers with different speeds, relative sliding friction will occur between the bottom surface of the glass and the rollers due to the difference in linear velocity, which can easily lead to scratches or breakage of the glass surface. In this embodiment, the physical height difference forces the glass to be driven by only a single speed during the handover, eliminating motion interference caused by the speed difference and maximizing the surface quality of the glass.

[0029] In this embodiment, the transition roller group 2 further includes two roller seat assemblies for rotatably connecting the transition roller 27. The roller seat assembly includes: a mounting plate 21 on which a mounting chamber 22 is fixed; a lifting rod 25, one end of which is located in the mounting chamber 22 and the other end of which slides out of the mounting chamber 22; a lifting device 23 fixed below the mounting chamber 22, with its output end extending into the mounting chamber 22 and connected to the lifting rod 25; and a roller seat 26 fixed to the top of the lifting rod 25 for rotatably connecting the transition roller 27.

[0030] When the height of the transition roller 27 needs to be adjusted, the lifter 23 drives the lifting rod 25 to move in a straight line within the mounting chamber 22. Since the roller seat 26 is fixed to the top of the lifting rod 25 and the transition roller 27 is rotatably connected to the roller seat 26, the vertical displacement of the lifting rod 25 will directly drive the roller seat 26 and the transition roller 27 to move up and down synchronously. By controlling the lifter 23, the height of the upper surface of the transition roller 27 can be adjusted to keep it at a set position higher than the upper surface of the first roller body in the first transmission roller group 1, thereby meeting the height requirements for glass crossing transmission.

[0031] In specific applications, the lifting device 23 can be any one of a hydraulic cylinder, a pneumatic cylinder, or an electric push rod.

[0032] Furthermore, four locking arc plates 28 are arranged in a circumferential array inside the installation chamber 22. The locking arc plates 28 are hinged to the inner surface of the installation chamber 22 via a hinge frame 210. An elastic element 29 is attached to the inner surface of the locking arc plates 28. Locking pins 24 are threaded to both sides of the installation chamber 22. A universal hinge ball is hinged to the center of the locking pin 24. Two hinge rods 211 are hinged to the universal hinge ball. The end of the hinge rod 211 away from the locking pin 24 is correspondingly hinged to the locking arc plate 28.

[0033] Furthermore, the outer surface of the lifting rod 25 is provided with a plurality of spikes 251.

[0034] When it is necessary to lock the lifting rod 25 at a set height, the operator rotates the locking pins 24 that are threaded on both sides of the installation chamber 22. Due to the constraint of the threaded pair, the rotational motion of the locking pins 24 is converted into linear movement along the axial direction of the installation chamber 22. As the locking pins 24 are axially displaced, the hinge rod 211 transmits the axial force from the locking pins 24 to the locking arc plate 28. Since the four locking arc plates 28 are hinged to the inner surface of the installation chamber 22 through the hinge frame 210 and are distributed in a circumferential array, the driving force of the hinge rod 211 will force the locking arc plates 28 to swing around their hinge points, thereby closing and holding the lifting rod 25 located in the middle.

[0035] During the locking process, the elastic element 29 attached to the inner surface of the locking arc plate 28 first contacts the lifting rod 25. As the locking force increases, the elastic element 29 undergoes elastic deformation and tightly wraps around the outer surface of the lifting rod 25.

[0036] Specifically, because the outer surface of the lifting rod 25 is provided with multiple spikes 251, under the action of the high-pressure radial force transmitted by the elastic element 29, the spikes 251 and the locking arc plate 28 generate a mechanical interlocking action. This interlocking action, combined with the positive pressure, generates a large static friction force and mechanical interlocking resistance between the lifting rod 25 and the mounting chamber 22, thereby firmly locking the lifting rod 25 in the current position.

[0037] In this embodiment, the upper surface of the transition roller 27 is 5mm-20mm higher than the upper surface of the first roller. When the glass moves from the first transfer roller group 1 to the transition roller group 2, this height difference acts as a physical step. The glass is lifted up by the height difference the instant it contacts the transition roller 27. The lower limit height of 5mm is sufficient to overcome the deflection caused by the weight of the glass and the cumulative errors in equipment manufacturing and installation, ensuring that the glass can reliably detach from the first roller and avoiding contact from below due to slight bending of the glass. The upper limit height of 20mm limits the steepness of the "climb," preventing a violent impact between the glass end and the transition roller 27 due to excessive height difference, and ensuring a smooth transition of the glass.

[0038] The distance between the transition roller 27 and the adjacent first roller is 80mm-200mm; the distance between the transition roller 27 and the adjacent second roller is 80mm-200mm, forming a non-contact buffer zone. When the glass is supported and lifted on the transition roller 27, the suspended portion of the glass spans the aforementioned distance.

[0039] In this embodiment, the second transmission roller group 3 also has a notch to form an accommodating space 4 for installing the side unloading assembly 5. The side unloading assembly 5 includes: an unloading plate 51, one end of which is hinged to the second transmission roller group 3; a plurality of wheel seats 52 fixed on the unloading plate 51, and a rotating seat 53 rotatably mounted on the wheel seats 52, with a return torsion spring between the rotating seat 53 and the wheel seats 52; a wheel body 54 rotatably mounted on the rotating seat 53, and in the initial state, the central axis of the wheel body 54 is parallel to the central axis of the second roller body, and the wheel body 54 is flush with the upper surface of the second roller body; a telescopic cylinder 55 hinged between the unloading plate 51 and the second transmission roller group 3; the center of gravity of the rotating seat 53 and the wheel body 54 mounted thereon is offset from the rotation center axis of the rotating seat 53.

[0040] In the initial state (i.e., the normal glass transport state), the telescopic cylinder 55 is in its retracted stroke, driving the feed plate 51 to remain horizontal. At this time, under the action of the return torsion spring, the central axis of the wheel 54 remains parallel to the central axis of the second roller, and the upper surface of the wheel 54 is flush with the upper surface of the second roller. In this state, the wheel 54 essentially acts as an extension auxiliary roller of the second transport roller group 3, and the glass can smoothly move from the second transport roller group 3 past the wheel 54 at the notch and continue to be transported forward without any obstruction.

[0041] When lateral feeding of glass is required, the piston rod of the telescopic cylinder 55 extends. In practical applications, the telescopic cylinder 55 can be any of a hydraulic cylinder, a pneumatic cylinder, or an electric actuator. As the telescopic cylinder 55 extends, the feeding plate 51 deflects laterally about its hinge point with the second transfer roller group 3.

[0042] During the deflection of the feed plate 51, utilizing the principle of mechanical balance, the center of gravity of the components consisting of the rotating base 53 and the wheel 54 mounted on it is designed to be offset from the rotation axis of the rotating base 53. As the tilt angle of the feed plate 51 changes, this eccentric center of gravity generates a torque relative to the rotation axis of the rotating base 53 under the action of gravity. This torque drives the rotating base 53 to rotate around its own axis relative to the wheel seat 52, thereby causing the wheel 54 to deflect synchronously. This process overcomes the resistance of the return torsion spring and realizes the automatic switching of the wheel 54's posture.

[0043] When the telescopic cylinder 55 extends to the predetermined stroke and the unloading plate 51 tilts into place, under the action of gravitational torque, the wheel 54 changes from the original longitudinal support to the lateral guidance or lateral transmission state. In conjunction with the overall tilting posture of the unloading plate 51, the glass slides down along the arrangement direction of the wheel 54 under the action of gravity and inertia, thereby completing the action of unloading from the side of the main transmission line.

[0044] In this embodiment, a guide component 6 is also provided on one side of the second transmission roller group 3. The guide component 6 includes a first guide plate 61, which is arranged perpendicular to the transmission direction of the second transmission roller group 3. The first guide plate 61 is used to guide the glass for side unloading.

[0045] The first guide plate 61 has a clearance groove on the side near the second transmission roller group 3; the guide assembly 6 also includes: a rotating shaft 62, which is rotatably mounted on the first guide plate 61; a second guide plate 63, which is fixed on the rotating shaft 62 and located in the clearance groove; and an adjusting cylinder 64, which is hinged between the rotating shaft 62 and the first guide plate 61.

[0046] When it is necessary to classify the glass during the side feeding process, the adjusting cylinder 64 drives the rotating shaft 62 to rotate, causing the second guide plate 63 located in the relief groove to deflect downward. At this time, the second guide plate 63 forms a slope that is inclined downward relative to the first guide plate 61. When the glass is conveyed to this position, it smoothly transitions onto the downwardly deflected second guide plate 63 and slides out along the inclined direction of the second guide plate 63, realizing the diversion and classification of the glass.

[0047] In specific applications, the adjusting cylinder 64 can be any one of a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, and its extension and retraction stroke can be controlled to precisely adjust the deflection timing and angle of the second guide plate 63.

[0048] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
