Description

Technical Field

[0001] This application relates to the field of tempering furnace maintenance technology, and in particular to a conveyor roller transfer system and method. Background Technology

[0002] In the field of solar glass deep processing, tempering is one of the core processes. Currently, tempering furnaces are widely used in the market for conveying and heating glass. The glass is conveyed on multiple parallel conveyor rollers (ceramic rollers) and undergoes a high-temperature heating process. However, after long-term operation, substances volatilized from the glass during the high-temperature heating process will inevitably adhere to the surface of the conveyor rollers. These deposits will cause a decrease in the surface smoothness of the conveyor rollers. Since the conveyor rollers are in direct contact with the glass surface, they are very likely to cause quality defects such as scratches and abrasions on the glass surface, affecting the yield and appearance quality of the glass products.

[0003] In existing technology, the conventional method for replacing conveyor rollers is to first raise the upper furnace body of the tempering furnace to a high height to expose the conveyor rollers that need to be replaced. Then, operators need to wear heavy, high-temperature protective gear (such as heat-resistant clothing, masks, and high-temperature gloves), and use simple tools such as crowbars to closely and individually disassemble the conveyor rollers to be replaced, and then manually lift and move them. The lifting of the upper furnace body results in significant energy loss. Specifically, to obtain sufficient lifting and moving space, the upper furnace body needs to be raised to a considerable height, which creates a large gap between the upper and lower furnace bodies, allowing the high-temperature heat accumulated inside the furnace to escape rapidly through this gap.

[0023] In the field of solar glass deep processing, tempering is one of the core processes. Currently, tempering furnaces are widely used in the market for conveying and heating glass. The glass is conveyed on multiple parallel conveyor rollers (ceramic rollers) and undergoes a high-temperature heating process. However, after long-term operation, substances volatilized from the glass during the high-temperature heating process will inevitably adhere to the surface of the conveyor rollers. These deposits will cause a decrease in the surface smoothness of the conveyor rollers. Since the conveyor rollers are in direct contact with the glass surface, they are very likely to cause quality defects such as scratches and abrasions on the glass surface, affecting the yield and appearance quality of the glass products.

[0024] In existing technology, the conventional method for replacing conveyor rollers is to first raise the upper furnace body of the tempering furnace to a high height to expose the conveyor rollers that need to be replaced. Then, operators need to wear heavy, high-temperature protective gear (such as heat-resistant clothing, masks, and high-temperature gloves), and use simple tools such as crowbars to closely and individually disassemble the conveyor rollers to be replaced, and then manually lift and move them. The lifting of the upper furnace body results in significant energy loss. Specifically, to obtain sufficient lifting and moving space, the upper furnace body needs to be raised to a considerable height, which creates a large gap between the upper and lower furnace bodies, allowing the high-temperature heat accumulated inside the furnace to escape rapidly through this gap.

[0025] like Figure 1 As shown, in view of this, the present invention provides a conveyor roller transfer system 100, which includes a pushing device 110 and a receiving device 120.

[0026] like Figure 1 As shown, during operation, the pushing device 110 is placed on one side of the tempering furnace 200 and positioned opposite the axial end of the conveyor roller 230 that needs to be replaced.

[0027] like Figure 3As shown, specifically, the pushing device 110 includes a first base frame 111, a first lifting drive mechanism 112, and a pushing mechanism 113. The first base frame 111 forms the supporting foundation of the entire pushing device 110; the first lifting drive mechanism 112 is mounted on the first base frame 111; the pushing mechanism 113 is mounted on the first lifting drive mechanism 112, and the first lifting drive mechanism 112 can drive the pushing mechanism 113 to rise and fall; wherein, the pushing mechanism 113 includes a pushing source 1131 and a roller end connecting assembly 1132, the pushing source 1131 is the component that generates pushing power, the roller end connecting assembly 1132 can be driven by the pushing source 1131, and the roller end connecting assembly 1132 is used to connect the first end of the conveying roller 230.

[0028] like Figure 3 As shown, multiple first rollers 1111 can be installed on the bottom of the first base frame 111 for movement on the ground.

[0029] like Figure 3 As shown, the first lifting drive mechanism 112 is used to drive the pushing mechanism 113 to rise and fall in the vertical direction so that the pushing axis of the pushing mechanism 113 is aligned with the axis of the conveying roller 230 to be replaced in the tempering furnace 200, so as to accommodate the differences in the height of the lower furnace body 210 and the installation height of the conveying roller 230 of different specifications of tempering furnace 200.

[0030] Combination Figure 3 and Figure 5 In some embodiments, the first lifting drive mechanism 112 includes a first drive assembly 1121, a first support rod 1122, a second support rod 1123, and a first support platform 1124. The first support rod 1122 and the second support rod 1123 are arranged crosswise and rotatably connected. Specifically, the first support rod 1122 and the second support rod 1123 are crosswise hinged at their middle parts by a pivot, forming an "X" shape. The bottom end of the first support rod 1122 is rotatably and slidably engaged with the first base frame 111. Specifically, the bottom end of the first support rod 1122 is rotatably connected to a first slider 1113 slidably disposed on the first base frame 111 via a rotating shaft. The first slider 1113 is sleeved on the first guide rod 1112, which provides guidance for the first slider 1113. The top end of the first support rod 1122 is rotatably connected to the first support platform 1124 via a rotating shaft. The bottom end of the second support rod 1123 is rotatably connected to the first base frame 111 via a rotating shaft, and its top end is rotatably connected to the second drive assembly 1221 via a rotating shaft.

[0031] The second drive assembly 1221 is used to drive the angle between the first support rod 1122 and the second support rod 1123 to change, thereby realizing the lifting and lowering of the first support platform 1124. In this embodiment, the second drive assembly 1221 includes a first handwheel 11211, a first lead screw 11212, a second guide rod 11213, and a second slider 11214; the first lead screw 11212 is connected to the first support platform 1124 through a bearing, one end of the first lead screw 11212 is fixedly connected to the first handwheel 11211, the second guide rod 11213 is fixed to the first support platform 1124 and is arranged parallel to the first lead screw 11212, the second slider 11214 is provided with an internal threaded hole and a through hole, the first lead screw 11212 passes through the internal threaded hole of the second slider 11214, and the second guide rod 11213 passes through the through hole of the second slider 11214.

[0032] When the operator rotates the first handwheel 11211, the first lead screw 11212 rotates accordingly, driving the cooperating second slider 11214 to move. The movement of the second slider 11214 changes the relative distance between the top ends of the first support rod 1122 and the second support rod 1123. When the top ends of the first support rod 1122 and the second support rod 1123 approach each other, they lift the first support platform 1124 upwards, achieving an upward movement. Conversely, when the top ends of the first support rod 1122 and the second support rod 1123 move away from each other, the first support platform 1124 descends.

[0033] In some other embodiments, the first drive assembly 1121 may also use a hydraulic cylinder or an electric push rod to drive the angle between the first support rod 1122 and the second support rod 1123 to change, thereby realizing the lifting and lowering of the first support platform 1124.

[0034] Combination Figure 3 and Figure 4 The pushing mechanism 113 is mounted on the first lifting drive mechanism 112, specifically on the first support platform 1124. The first lifting drive mechanism 112 drives the pushing mechanism 113 to move up and down. The pushing source 1131 of the pushing mechanism 113 is the element that generates pushing power. The pushing source 1131 can be a cylinder, hydraulic cylinder, or electric cylinder. The pushing source 1131 has a telescopic shaft 11311, which can perform linear telescopic movement along its axial direction. Figure 2 and Figure 4The roller end connecting assembly 1132 of the pushing mechanism 113 is connected to the telescopic shaft 11311 of the pushing source 1131. Specifically, the roller end connecting assembly 1132 includes a clamping sleeve 11321 and a clamping clamp 11322. The clamping sleeve 11321 is a hollow cylindrical sleeve. The inner diameter of one end of the sleeve is adapted to the outer diameter of the telescopic shaft 11311 and is used to fit and fix it to the actuating end of the telescopic shaft 11311. The inner diameter of the other end of the sleeve is adapted to the outer diameter of the first end of the conveying roller 230 and is used to fit onto the first end of the conveying roller 230. The clamp 11322 is fitted over the end of the clamping sleeve 11321 used to connect the conveyor roller 230. The clamp 11322 includes the clamp body 113221 and the fastener 113222. After the clamping sleeve 11321 is fitted over the first end of the conveyor roller 230, the operator can tighten the fastener 113222 (e.g., by hand-tightening a screw) to make the clamp body 113221 radially contract, thereby firmly clamping the clamping sleeve 11321 to the first end of the conveyor roller 230 to form a reliable connection.

[0035] In order to clamp telescopic shafts 11311 and conveyor rollers 230 of different diameters (with manufacturing tolerances), the clamping sleeve 11321 is provided with an opening 113211 extending through it axially, and the opening 113211 also extends through the inner and outer side walls of the clamping sleeve 11321, giving it a certain radial contraction elasticity. Furthermore, the roller end connecting assembly 1132 also includes a locking shaft 11323, which is used to fix the clamping sleeve 11321 to the actuating end of the telescopic shaft 11311. Specifically, the actuator end of the telescopic shaft 11311 is provided with a first through hole that extends radially through it, and the side wall of the clamping sleeve 11321 is provided with two second through holes that are radially opposite each other. When the clamping sleeve 11321 is fitted into place, the locking shaft 11323 is passed through one second through hole, the first through hole and the other second through hole in sequence, thereby locking the clamping sleeve 11321 and the telescopic shaft 11311 in the circumferential direction to prevent relative rotation between the two. At the same time, the passage of the locking shaft 11323 also plays a role in axial positioning.

[0036] like Figure 1 As shown, during operation, the receiving device 120 is placed on the other side of the tempering furnace 200 and is positioned opposite the other axial end of the conveyor roller 230 that needs to be replaced. The conveyor roller 230 to be replaced is pushed out by the pushing device 110 and finally delivered to the receiving device 120.

[0037] like Figure 6As shown, specifically, the receiving device 120 includes a second base frame 121, a second lifting drive mechanism 122, and a receiving mechanism 123. The second base frame 121 is the supporting foundation of the receiving device 120; the second lifting drive mechanism 122 is mounted on the second base frame 121; the receiving mechanism 123 is mounted on the second lifting drive mechanism 122, and the second lifting drive mechanism 122 can drive the receiving mechanism 123 to rise and fall.

[0038] The bottom of the second base frame 121 can be equipped with multiple second rollers 1211 for movement on the ground.

[0039] Combination Figure 6 and Figure 8 The purpose of the second lifting drive mechanism 122 is to drive the receiving mechanism 123 to rise and fall vertically so that it can be aligned with and receive the conveyor roller 230 pushed out from the tempering furnace 200. It should be noted that since the receiving device 120 needs to work in conjunction with the pushing device 110, the lifting heights of the two need to be adjusted separately to adapt to the axial height of the same conveyor roller 230.

[0040] Specifically, the second lifting drive mechanism 122 includes a second drive assembly 1221, a third support rod 1222, a fourth support rod 1223, and a second support platform 1224. The third support rod 1222 and the fourth support rod 1223 are arranged crosswise and rotatably connected. Specifically, the third support rod 1222 and the fourth support rod 1223 are crosswise hinged at their middle parts by a pivot, forming an "X" shape. The bottom end of the third support rod 1222 is rotatably and slidably engaged with the second base frame 121. Specifically, the bottom end of the third support rod 1222 is rotatably connected to a third slider 1213 slidably disposed on the second base frame 121 via a rotating shaft. The third slider 1213 is sleeved on the third guide rod 1212, which provides guidance for the third slider 1213. The top end of the third support rod 1222 is rotatably connected to the second support platform 1224 via a rotating shaft. The bottom end of the fourth support rod 1223 is rotatably connected to the second base frame 121 via a rotating shaft, and its top end is rotatably connected to the second drive assembly 1221 via a rotating shaft.

[0041] The second drive assembly 1221 is used to drive the angle between the third support rod 1222 and the fourth support rod 1223 to change, thereby realizing the lifting and lowering of the second support platform 1224. In this embodiment, the second drive assembly 1221 includes a second handwheel 12211, a second lead screw 12212, a fourth guide rod 12213, and a fourth slider 12214; the second lead screw 12212 is connected to the second support platform 1224 through a bearing, one end of the second lead screw 12212 is fixedly connected to the second handwheel 12211, the fourth guide rod 12213 is fixed to the second support platform 1224 and is arranged parallel to the second lead screw 12212, the fourth slider 12214 is provided with an internal threaded hole and a through hole, the second lead screw 12212 passes through the internal threaded hole of the fourth slider 12214, and the fourth guide rod 12213 passes through the through hole of the fourth slider 12214.

[0042] When the operator rotates the second handwheel 12211, the second lead screw 12212 rotates accordingly, driving the cooperating fourth slider 12214 to move. The movement of the fourth slider 12214 changes the relative distance between the top ends of the third support rod 1222 and the fourth support rod 1223. When the top ends of the third support rod 1222 and the fourth support rod 1223 approach each other, they lift the second support platform 1224 upwards, achieving an upward movement. Conversely, when the top ends of the third support rod 1222 and the fourth support rod 1223 move away from each other, the second support platform 1224 descends.

[0043] In some other embodiments, the second drive assembly 1221 may also use a hydraulic cylinder or an electric push rod to drive the angle between the third support rod 1222 and the fourth support rod 1223 to change, thereby realizing the lifting and lowering of the second support platform 1224.

[0044] Combination Figure 6 and Figure 7 The receiving mechanism 123 is mounted on the second support platform 1224 of the second lifting drive mechanism 122 and rises and falls together with the second support platform 1224. The receiving mechanism 123 is used to receive the conveying roller 230 sent out by the pushing device 110 and provide it with a temporary storage position.

[0045] In some embodiments, the receiving mechanism 123 includes an arc-shaped receiving frame 1231 with its concave arc-shaped surface facing upwards, for supporting the conveyor roller 230. The axial direction (i.e., its length direction) of the arc-shaped receiving frame 1231 is set to be parallel to the axial direction of the conveyor roller 230 to be received, or more preferably, in the receiving state, its axial direction is coaxial with the axial direction of the conveyor roller 230. The arc-shaped receiving frame 1231 can automatically center and limit the conveyor roller 230, preventing it from rolling and falling after being received.

[0046] Furthermore, the receiving mechanism 123 also includes rollers 1232 disposed on the arc-shaped receiving frame 1231. Even further, the rollers 1232 are arranged in at least one row, with multiple rollers 1232 in each row arranged along the arc length of the arc-shaped receiving frame 1231. In this way, the conveying roller 230 actually rests on these rollers 1232, and its contact with the receiving mechanism 123 is a rolling contact with minimal frictional resistance, facilitating easy removal from the receiving device 120 by the operator.

[0047] Furthermore, there are multiple receiving mechanisms 123, which are spaced apart, and the spacing direction of the multiple receiving mechanisms 123 is parallel to the axial direction of the conveying roller 230 to be received.

[0048] like Figure 1 As shown, to more clearly illustrate the working process of this system, it is necessary to first describe the tempering furnace 200. The tempering furnace 200 typically includes a lower furnace body 210 and a liftable upper furnace body 220. Heating wires are installed inside the lower furnace body 210 to provide the high-temperature heat source required for glass tempering. Multiple conveying rollers 230 are arranged in parallel and horizontally mounted on the lower furnace body 210 via bearings 231. Specifically, bearings 231 are fitted at both ends of the conveying rollers 230, and the bearings 231 are fixed to the lower furnace body 210 by pressure plates. During normal operation, the conveying rollers 230 are driven to rotate by a motor, conveying the glass sheet from one end of the tempering furnace 200 to the other.

[0049] This application also provides a conveyor roller transfer method, which applies the conveyor roller transfer system of the above embodiments. The conveyor roller transfer method includes: S100, the pushing device 110 is moved to one side of the tempering furnace 200, and the height of the pushing device 113 is adjusted by the first lifting drive mechanism 112 so that the roller end connecting assembly 1132 is flush with the first end of the conveying roller 230 and the roller end connecting assembly 1132 is connected to the first end of the conveying roller 230. S200, move the receiving device 120 to the other side of the tempering furnace 200, and adjust the height of the receiving device 123 by the second lifting drive mechanism 122; S300, the push source 1131 drives the conveyor roller 230 to move along the axial direction of the conveyor roller, so that the conveyor roller 230 is pushed onto the receiving mechanism 123.

[0050] Specifically: First, locate the conveyor roller 230 that needs to be replaced, and the operator manually removes the pressure plate of the bearing 231 that is pressed on the conveyor roller 230.

[0051] Next, the operator moves the pusher 110 by moving the handle, moving it to one side of the tempering furnace 200, and aligning the roller end connecting assembly 1132 approximately with the first end of the conveyor roller 230. Then, the operator operates the first handwheel 11211 to drive the first lifting drive mechanism 112, adjusting the height of the pusher 113 until the axis of the clamping sleeve 11321 in the roller end connecting assembly 1132 coincides with the axis of the first end of the conveyor roller 230. The operator then places the clamping sleeve 11321 from the roller end connecting assembly 1132 of the pusher 110 onto the exposed first end of the conveyor roller 230 and pushes it to a predetermined depth. Subsequently, the clamping sleeve 11321 is securely held to the end of the conveyor roller 230 using the clamp 11322. Similarly, the operator moves the receiving device 120 to the other side of the tempering furnace 200 and operates its second lifting drive mechanism 122 to adjust the height of the receiving mechanism 123 so that the upper surface of its arc-shaped receiving frame 1231 is slightly lower than or exactly aligned with the lower generatrix of the second end of the conveying roller 230, so as to ensure that the conveying roller 230 can land smoothly on the receiving mechanism 123 after being pushed out.

[0052] Next, the push source 1131 is activated, causing it to drive the telescopic shaft 11311 to extend into the tempering furnace 200. Since the telescopic shaft 11311 is fixedly connected to the first end of the conveying roller 230 via the roller end connecting assembly 1132, the extension movement of the telescopic shaft 11311 will directly push the conveying roller 230 to move axially towards the other side of the tempering furnace 200. During this process, the other end of the conveying roller 230 gradually extends from the other side of the tempering furnace 200. As the pushing action continues, most of the length of the conveying roller 230 will gradually leave the furnace body, and its second end will first contact the arc-shaped receiving frame 1231 of the receiving device 120 and continue to move forward on it until the conveying roller 230 is completely detached from the tempering furnace 200, and the entire roller body is supported on the receiving mechanism 123 of the receiving device 120.

[0053] Finally, after the conveyor roller 230 has been fully pushed onto the receiving device 120, the operator loosens the clamp 11322, allowing the roller end connecting assembly 1132 to separate from the old conveyor roller 230 that has been replaced.

[0054] In this application, the process of removing the conveyor roller 230 from the tempering furnace eliminates the need for any lifting operation of the upper furnace body 220 of the tempering furnace 200, thereby improving the problem of heat loss inside the furnace, maintaining the stability of the furnace temperature, and avoiding energy waste.
