Description

Technical Field

[0001] This utility model relates to the field of roller replacement technology, and in particular to a lifting mechanism, roller changing device and float glass production line structure. Background Technology

[0002] In the production of float glass, roller conveyors are used to carry the glass and move it in a predetermined direction. These conveyors typically consist of multiple rollers that operate continuously at high temperatures to ensure the smooth movement of the glass. However, due to prolonged operation under high temperature and high load conditions, the rollers in the conveyor are prone to wear, corrosion, or buildup, which can affect the surface quality of the glass and the overall efficiency of the production line.

[0003] When a roller in the roller conveyor malfunctions and needs to be replaced, the current common practice is to use a lifting mechanism to move directly relative to the roller conveyor, lift the roller that needs to be replaced, remove it from the roller conveyor, and then replace or repair it.

[0004] However, the lifting height of the lifting mechanism is generally fixed. When the height of the roller conveyor is too high, the lifting mechanism cannot lift the roller that needs to be replaced to a suitable height, which causes the lifting mechanism to interfere with other parts or glass on the roller conveyor and cause collisions. Utility Model Content

[0005] The main purpose of this invention is to propose a lifting mechanism, a roller changing device, and a float glass production line structure, which aims to reduce interference problems caused when changing rollers.

[0007] A movable base, which can move along the extension direction of the roller conveyor;

[0008] A lifting assembly, disposed on the movable base, the lifting assembly having a lifting surface, the lifting assembly driving the lifting surface to push the roller out of the roller conveyor; and

[0009] A fine-tuning component is provided, with its two ends connected to the movable base and the lifting component, respectively. Along the moving direction of the lifting component, the fine-tuning component is used to adjust the height of the lifting component.

[0010] In one embodiment, the lifting assembly includes:

[0011] A lifting drive unit, which is connected to the fine-tuning assembly; and

[0012] A lifting member is connected to the output end of the lifting drive member, and the lifting member has the lifting surface.

[0013] In one embodiment, the lifting member includes:

[0014] The base is connected to the output end of the lifting drive; and

[0015] A support portion, which is connected to the base portion, and the support portion having an inwardly recessed lifting surface.

[0016] In one embodiment, the fine-tuning component includes:

[0017] The main body component, with its two ends respectively connected to the movable base and the lifting assembly; and

[0018] An adjusting member is movably disposed on the main body and can rotate about the axis of the adjusting member to adjust the height of the main body.

[0019] This utility model also proposes a roller changing device for use in a conveying device, wherein the conveying device is movably equipped with multiple rollers and a roller conveyor formed by the multiple rollers for transporting products, and the roller changing device includes:

[0020] Multiple detection sensors are provided on the conveying device along the extension direction of the roller conveyor, for detecting whether there is a product between two adjacent detection sensors;

[0021] The aforementioned lifting mechanism corresponds to the roller conveyor and is located between two adjacent detection sensors; and

[0022] The controller is electrically connected to both the detection sensor and the lifting mechanism, and is used to control the lifting mechanism to lift the rollers of the roller conveyor when there is no product between two adjacent detection sensors.

[0023] In one embodiment, the roller changing device lifts the roller, and the lifted roller and the roller conveyor enclose a transport space, through which the product passes along the roller conveyor.

[0024] In one embodiment, two lifting mechanisms are provided, and the two lifting mechanisms simultaneously clamp both ends of the roller.

[0025] In one embodiment, at least one roller is located between two adjacent detection sensors along the extension direction of the roller conveyor.

[0026] In one embodiment, along the extending direction of the roller conveyor, the distance between two adjacent detection sensors is S, and the distance between two adjacent products is T, where S≤T.

[0027] This utility model also proposes a float glass production line structure, characterized in that the float glass production line structure includes:

[0028] A conveying device, comprising a frame and a plurality of rollers movably mounted on the frame along a first direction, the surfaces of the rollers forming a roller track for transporting products; and

[0029] The roller changing device described above is arranged adjacent to the conveying device.

[0030] The technical solution of this utility model is to move the lifting mechanism to the roller that needs to be replaced by moving the base, and the height of the lifting component is adjusted by the fine-tuning component so that the lifting component is close to the roller table. Then the lifting component drives the lifting surface to push the roller out of the roller table, thereby effectively solving the interference problem caused when replacing the roller.

[0041] In the production of float glass, roller conveyors are used to carry the glass and move it in a predetermined direction. These conveyors typically consist of multiple rollers that operate continuously at high temperatures to ensure the smooth movement of the glass. However, due to prolonged operation under high temperature and high load conditions, the rollers in the conveyor are prone to wear, corrosion, or buildup, which can affect the surface quality of the glass and the overall efficiency of the production line.

[0042] When a roller in the roller conveyor malfunctions and needs to be replaced, the current common practice is to use a lifting mechanism to move directly relative to the roller conveyor, lift the roller that needs to be replaced, remove it from the roller conveyor, and then replace or repair it.

[0043] However, the lifting height of the lifting mechanism is generally fixed. When the height of the roller conveyor is too high, the lifting mechanism cannot lift the roller that needs to be replaced to a suitable height, which causes the lifting mechanism to interfere with other parts or products on the roller conveyor and cause collisions.

[0044] This utility model proposes a lifting mechanism 100, which aims to reduce interference problems when changing rollers 61.

[0045] Please see Figures 1 to 3 In one embodiment of this utility model, the lifting mechanism 100 is used to eject the roller 61 in the roller conveyor 62. The lifting mechanism 100 includes a movable base 1, a lifting component 2, and a fine-tuning component 3. The movable base 1 is movable along the extending direction of the roller conveyor 62. The lifting component 2 is disposed on the movable base 1 and has a lifting surface 2221. The lifting component 2 drives the lifting surface 2221 to eject the roller 61 out of the roller conveyor 62. The two ends of the fine-tuning component 3 are respectively connected to the movable base 1 and the lifting component 2. Along the moving direction of the lifting component, the fine-tuning component 3 is used to adjust the height of the lifting component 2.

[0046] The lifting mechanism 100 of this utility model moves the lifting mechanism 100 to the roller 61 that needs to be replaced by moving the base 1. The fine-tuning component 3 adjusts the height of the lifting component 2 so that the lifting component 2 is close to the roller table 62. Then the lifting component 2 drives the lifting surface 2221 to push the roller 61 out of the roller table 62, thereby effectively solving the interference problem caused when replacing the roller 61.

[0047] In this embodiment, the movable base 1 includes a plate 11 and four casters 12 located below the plate 11. The lifting mechanism 100 can move freely in the plane by the rolling of the casters 12.

[0048] Optionally, the movable base 1 may also include a slide rail and a plate 11 movably disposed on the slide rail. In this case, the extension direction of the slide rail is consistent with the extension direction of the roller conveyor 62, so that the lifting mechanism 100 can move to the corresponding roller 61 that needs to be replaced.

[0049] Please see Figures 1 to 3 In one embodiment, the fine-tuning component 3 includes a main body 31 and an adjusting component 32. The two ends of the main body 31 are respectively connected to the movable base 1 and the lifting component 2. The adjusting component 32 is movably disposed on the main body 31 and can rotate about the axis of the adjusting component 32 to adjust the height of the main body 31.

[0050] In this embodiment, the main body 31 includes an upper frame 311 and a lower frame 312 that are rotatably connected to each other. The adjusting member 31 is rotatably connected to the upper frame 311 and the lower frame 312 respectively. By rotating the adjusting member 31, the upper frame 311 and the lower frame 312 are brought closer to or further away from each other, thereby adjusting the height of the main body 31 so that the lifting assembly 2 can approach the roller conveyor 62 and avoid interference problems after the lifting assembly 2 lifts the roller 61.

[0051] However, the roller conveyor 62 in actual production often has a slight tilt. This tilt may be caused by installation errors, deformation during long-term use, or improper adjustment. Due to the tilt, the lifting mechanism 100 will deviate when positioning the roller 61 that needs to be replaced, and uneven force is likely to occur during the lifting process, thus affecting the smooth replacement of the roller 61.

[0052] Therefore, to solve the above problems, in another embodiment, the fine-tuning component 3 consists of four adjusting bolts (not shown). These four adjusting bolts are respectively connected to the movable base 1 and the lifting component 2, and correspond to the four corners of the lifting component 2. When only the height of the lifting component 2 needs to be adjusted, all four adjusting bolts can be adjusted to extend or retract by the same length simultaneously, thereby changing the height of the lifting component 2. When the roller conveyor 62 has a tilt problem, the four adjusting bolts can be adjusted to extend or retract to different heights, allowing the lifting component 2 to adapt to roller conveyors 62 with different tilt angles, ensuring that the movement direction of the lifting component 2 is exactly perpendicular to the extension direction of the roller conveyor 62, and that the lifting surface 2221 is directly facing the roller 61 that needs repair.

[0053] It should be noted that when manually adjusting the extension length of the adjusting bolt, there may be issues with the adjustment accuracy. Therefore, a level (not shown) is needed to assist in adjusting the tilt angle of the lifting assembly 2 to ensure that the movement direction of the lifting assembly 2 is exactly perpendicular to the extension direction of the roller conveyor 62.

[0054] Please see Figures 1 to 3 In one embodiment, the lifting assembly 2 includes a lifting drive 21 and a lifting member 22. The lifting drive 21 is connected to the fine-tuning assembly 3. The lifting member 22 is connected to the output end of the lifting drive 21, and the lifting member 22 has a lifting surface 2221.

[0055] In this embodiment, the fine-tuning component 3 adjusts the height of the lifting drive component 21. The lifting drive component 21 can be driven by a cylinder or a motor. Furthermore, a stepper motor or a servo motor can also be used to improve the accuracy of lifting.

[0056] Please see Figures 1 to 3 In one embodiment, the lifting member 22 includes a base 221 and a support 222. The base 221 is connected to the output end of the lifting drive member 21. The support 222 is connected to the base 221, and the support 222 has an inwardly recessed lifting surface 2221.

[0057] In this embodiment, the base 221 of the lifting member 22 and the output end of the lifting drive member 21 can be connected by a bearing structure, a threaded structure, or a snap-fit ​​structure, which is not limited here, but the stability of the lifting member 22 during movement must be ensured. The support part 222 directly contacts the roller 61 to lift the roller 61. The inwardly recessed lifting surface 2221 can provide a more fitting and stable support, and can also effectively disperse pressure during the lifting process to protect the roller 61 from damage.

[0058] However, when a roller 61 on roller conveyor 62 malfunctions, such as causing abnormal noise, vibration, or uneven speed, stopping roller conveyor 62 and directly repairing it via lifting mechanism 100 will create new problems. The stagnation of roller conveyor 62 will not only interrupt the transport of product 400, causing it to accumulate on the production line and increasing the risk of breakage and scratches, but it will also affect the cooling effect of product 400 and subsequent processing, leading to a decline in product quality. Furthermore, stopping roller conveyor 62 will disrupt the rhythm of the entire production line, reduce production efficiency, and increase production costs.

[0059] To solve the above problems, this utility model also proposes a roller changing device 200, which includes multiple detection sensors 4, a controller 5 and a lifting mechanism 100. The specific structure of the lifting mechanism 100 is as described in the above embodiments. Since this roller changing device 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0060] Please see Figures 1 to 3 The roller changing device 200 is applied to the conveying device 6, which is movably equipped with multiple rollers 61 and a roller conveyor 62 formed by the multiple rollers 61 for transporting products 400. Multiple detection sensors 4 are disposed on the conveying device 6 along the extension direction of the roller conveyor 62 to detect whether there is a product 400 between two adjacent detection sensors 4. A lifting mechanism 100 corresponds to the roller conveyor 62 and is located between two adjacent detection sensors 4. A controller 5 is electrically connected to both the detection sensors 4 and the lifting mechanism 100, and is used to control the lifting mechanism 100 to lift the rollers 61 of the roller conveyor 62 when there is no product 400 between two adjacent detection sensors 4.

[0061] The roller changing device 200 of this invention uses multiple detection sensors 4 arranged along the extension direction of the roller conveyor 62 to monitor in real time whether there is a product 400 between adjacent detection sensors 4, ensuring that no product 400 passes between adjacent detection sensors 4 when changing roller 61, thereby avoiding impact on the production process and damage to the product 400. When no product 400 is detected between two adjacent detection sensors 4, the controller 5 will immediately activate the lifting mechanism 100 to lift the roller 61 at the corresponding position.

[0062] Please see Figures 1 to 3 In one embodiment, the roller changing device 200 lifts the roller 61, and the lifted roller 61 and the roller conveyor 62 enclose a transport space 611, through which the product 400 passes along the roller conveyor 62.

[0063] In this embodiment, after the roller changing device 200 lifts the roller 61 to be replaced from both ends of the roller 61, the lowest height at which the roller 61 is lifted is higher than the highest height of the product 400 on the roller 62 in the direction perpendicular to the roller conveyor 62. This allows the product 400 to still pass under the lifted roller 61, i.e., the transport space 611, driven by the roller conveyor 62, avoiding the product 400 from being stuck and ensuring the continuous transport of the product 400 on the roller conveyor 62.

[0064] Please see Figures 1 to 3 In one embodiment, two lifting mechanisms 100 are provided, and the two lifting mechanisms 100 simultaneously clamp both ends of the roller 61.

[0065] In this embodiment, by setting lifting mechanisms 100 at both ends of the roller 61, the two ends of the roller 61 can be lifted synchronously to a preset height, avoiding instability of the roller 61 during movement caused by uneven force at a single point.

[0066] Alternatively, only one lifting mechanism 100 may be provided. In this case, the lifting member 22 includes two support parts 222, which correspond to the two ends of the roller 61 respectively. This can also ensure the stability of the roller 61 when it moves.

[0067] Please see Figures 1 to 3 In one embodiment, there is at least one roller 61 between two adjacent detection sensors 4 along the extension direction of the roller conveyor 62.

[0068] In this embodiment, in order to ensure that the data detected by two adjacent detection sensors 4 are meaningful, there is at least one roller 61 between two adjacent detection sensors 4. When both adjacent detection sensors 4 detect no product 400, the roller 61 between the two adjacent detection sensors 4 can be replaced.

[0069] Please see Figures 1 to 3 In one embodiment, along the extending direction of the roller conveyor 62, the distance between two adjacent detection sensors 4 is S, and the distance between two adjacent products 400 is T, where S≤T.

[0070] Understandably, when the distance S between two adjacent detection sensors 4 is greater than the distance T between two adjacent products 400, at least one detection sensor 4 will detect product 400 regardless, and there is no opportunity to replace roller 61 at this time. Therefore, the distance between two adjacent detection sensors 4 can be adjusted accordingly based on the rotational speed of roller 61, the lifting speed of lifting mechanism 100, and the distance between two adjacent products 400.

[0071] In one embodiment, the detection sensor 4 is a photoelectric sensor.

[0072] In this embodiment, photoelectric sensors are installed between adjacent rollers 61. The photoelectric sensor emits a light signal. When the product 400 passes by, the light signal is blocked or reflected by the product 400. After receiving this change, the receiving end sends a signal to the controller 5, indicating that the product 400 is present at this location. Because the photoelectric sensor has the characteristic of non-contact detection, it will not cause any damage to the product 400 during transmission. At the same time, the photoelectric sensor has a fast response speed and can detect the presence of the product 400 in a very short time, ensuring the control accuracy of the controller 5.

[0073] This utility model also proposes a float glass production line structure 300, which includes a conveying device 6 and a roller changing device 200. The specific structure of the roller changing device 200 is as described in the above embodiments. Since this float glass production line structure 300 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0074] The conveying device 6 includes a frame 63 and a plurality of rollers 61 movably mounted on the frame 63 along a first direction. The surfaces of the rollers 61 form a roller conveyor 62 for transporting the product 400. A roller changing device 200 is disposed adjacent to the conveying device 6. In this embodiment, the rollers 61 are rotatably mounted on the frame 63, and different rollers 61 are connected by transmission gears. When a roller 61 needs to be replaced, it is first necessary to ensure that the faulty roller 61 and the transmission gear connected to it are separated. Then, the roller changing device 200 lifts the faulty roller to remove it from the roller conveyor 62.

[0075] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
