Abstract

Embodiments of the present application provide a sagger circulating line conveying system and method, relating to the field of lithium battery material transportation circulating line. It aims to improve the problem that the sagger cannot be stacked in sequence in the transportation circulating line, resulting in sagger sticking. The sagger circulating line conveying system comprises: a second conveying roller way for conveying a group of multi-layer stacked saggars to a disassembling station, a first lifting device for lifting the saggars above the bottom layer of saggars, a first jacking device for lowering the bottom layer of saggars onto the second conveying roller way, the second conveying roller way for conveying the lowered saggars in the upstream direction until a group of multi-layer stacked saggars from the bottom layer to the top layer of saggars are unfolded in sequence on the second conveying roller way in the direction from upstream to downstream; and the second conveying roller way for conveying the unfolded saggars in the downstream direction. After the disassembled saggars are conveyed in reverse, they are then conveyed together in the forward direction to ensure that the subsequent stacking of saggars can maintain the original stacking sequence and avoid sagger sticking.

Description

Technical Field

[0001] This invention relates to the field of lithium battery material transport circulation lines, and more specifically, to a crucible circulation line conveying system and method. Background Technology

[0002] In the lithium battery material transport circulation line, the raw materials for lithium batteries are stored in saggars. The saggars move along the circulation line with the rollers to achieve the purpose of transporting the raw materials for lithium batteries.

[0003] When the multi-layered saggers come out of the kiln, the material in the top sagger becomes sticky due to the chemical reaction. If the saggers cannot maintain the previous stacking order during the process of unfolding and re-stacking in the transport circulation line, such as the bottom saggers being reversed and the top saggers becoming the bottom saggers, the top saggers will stick together, causing production to be interrupted.

[0004] In addition, saggers are divided into flat-mouthed and notched types. If the disassembly method at the disassembly station is incorrect, resulting in the wrong stacking order of flat-mouthed and notched saggers, the material will not react sufficiently in the kiln, affecting product quality.

[0005] The normal stacking order of the saggers from top to bottom is: flat-mouthed sagger, notched sagger, and notched sagger, with the material weights added being 5 kg, 3 kg, and 4 kg respectively. If the stacking order of the saggers is disordered due to human error or equipment failure, it will directly affect production or output. Summary of the Invention

The first lifting device and the first supporting device are set at the disassembly station, with the first supporting device located above the first lifting device. After the second conveyor roller conveyor transports the stacked crucibles to the disassembly station, it disassembles the crucibles from the bottom layer to the top layer and then transports them in the reverse direction. After disassembly, the disassembled crucibles are transported forward together, with the bottom layer located upstream and the top layer located downstream. When stacking crucibles later, the top layer is stacked first, and then the bottom layer is stacked below the top layer in sequence. After stacking, the top layer crucibles are still located on the top layer, maintaining the previous stacking order, which completely solves the defect of crucible sticking.

[0028] The sagger circulation line conveying method, implemented using a sagger circulation line conveying system, can improve the problem of sagger sticking due to inconsistent stacking order during the transport circulation line. Attached Figure Description

[0043] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0044] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0045] The following is combined with Figures 1 to 8 The crucible circulation line conveyor system provided in this embodiment will be described in detail.

[0046] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 7 An embodiment of the present invention provides a crucible circulation line conveying system, including a first conveying roller conveyor 100, a second conveying roller conveyor 200, a first lifting device 230, and a first lifting device 240; the second conveying roller conveyor 200 is located downstream of the first conveying roller conveyor 100, and the second conveying roller conveyor 200 is capable of reciprocating along the upstream and downstream direction; a dismantling station 210 is provided at the downstream end of the second conveying roller conveyor 200, the first lifting device 230 and the first lifting device 240 are provided at the dismantling station 210, and the first lifting device 240 is located above the first lifting device 230;

[0047] The first conveyor roller 100 is used to convey a set of multi-layered overlapping saggers 11 to the second conveyor roller 200 each time; the second conveyor roller 200 is used to convey a set of multi-layered overlapping saggers 11 to the disassembly station 210; the first lifting device 240 is used to lift the saggers 11 above the bottom layer 11; the first lifting device 230 is used to lower the bottom layer sagger 11 onto the second conveyor roller 200; the second conveyor roller 200 is used to convey the lowered saggers 11 upstream until a set of multi-layered overlapping saggers 11 unfolds sequentially from the bottom layer to the top layer 11 along the upstream to downstream direction on the second conveyor roller 200; the second conveyor roller 200 is used to transfer the unfolded saggers 11 downstream.

[0048] It should be noted that, as those skilled in the art will understand, throughout this text, in the lithium battery material transport cycle line, the sagger 11 contains the raw materials for the production of ternary precursors for lithium batteries. After the sagger 11 is filled with raw materials, it is stacked along its height and sent into the kiln. After exiting the kiln, the stacked sagger 11 is unfolded, each sagger 11 is filled with raw materials, and then stacked again and sent into the kiln, thus repeating the cycle. Therefore, relatively speaking, on any segment of the lithium battery material transport cycle line, the sagger 11 moves from one device to the next, with the previous device being upstream relative to the next device, and the next device being downstream relative to the previous device; see reference. Figure 1 In this embodiment, the overlapping saggars 11 are conveyed from the first conveyor roller 100 to the second conveyor roller 200. The first conveyor roller 100 is located upstream of the second conveyor roller 200, and the second conveyor roller 200 is located downstream of the first conveyor roller 100. Similarly, the end of a device closer to the upstream device is the upstream end, and the end of a device closer to the downstream device is the downstream end. In this embodiment, the end of the second conveyor roller 200 closer to the first conveyor roller 100 is the upstream end, and the end of the second conveyor roller 200 farther from the first conveyor roller 100 is the downstream end.

[0049] "Upstream and downstream direction" includes both the direction from upstream to downstream and the direction from downstream to upstream. Figure 1 Taking the relative position in the middle as an example, "upstream and downstream direction" includes the direction from left to right and the direction from right to left.

[0050] Reference Figure 5 , Figure 5The process of disassembling the saucer 11 is demonstrated, using the three saucers 11 stacked from top to bottom as an example. The first lifting device 230 uses a lifting motor, and the first supporting device 240 uses a clamping cylinder. 1. The lifting motor is in the lower position, and the three saucers 11 are located on the second conveyor roller 200; 2. The lifting motor rises to the middle position, simultaneously lifting the three saucers 11 upwards, with the clamping cylinder corresponding to the bottom of the middle saucer 11; 3. The clamping cylinder lifts the bottom of the middle saucer 11, supporting and fixing the upper and middle saucers 11, while the lifting motor lowers the lower saucer 11 to the lower position, placing it onto the second conveyor roller 200; 4. The second conveyor roller 200 transports the upper saucer 11 upstream; 5. The lifting motor rises to the upper position, supporting the bottom of the middle saucer 11; 6. The clamping cylinder releases the middle saucer. 11. The lifting motor lowers the middle sagger 11 to its lower position, while the upper and middle saggers 11 move downwards, with the bottom of the upper sagger 11 aligning with the clamping cylinder; 7. The clamping cylinder lifts and fixes the bottom of the upper sagger 11, and the lifting motor supports the middle sagger 11; 8. The lifting motor supports the middle sagger 11 and moves it downwards, placing it onto the second conveyor roller conveyor 200; 9. The second conveyor roller conveyor 200 transports the middle sagger 11 upstream; 10. The lifting motor rises to its upper position, supporting the bottom of the upper sagger 11; 11. The clamping cylinder releases the lower sagger 11, and the lifting motor lowers to its lower position, placing the lower sagger 11 onto the second conveyor roller conveyor 200. In this way, the upper sagger 11, middle sagger 11, and lower sagger 11 can be disassembled sequentially. Figure 5 As shown in the process, the dismantling process is from the bottom layer to the top layer; the clamping cylinder releases one crucible 11 each time, and the lifting motor lifts one crucible 11 each time and places it on the second conveyor roller 200, gradually completing the unfolding of multiple overlapping crucibles 11.

[0051] Figure 6 The process of stacking bowls was demonstrated, and Figure 5 The dismantling process of the shown sagger 11 is the reverse. The lifting motor lifts one sagger 11 at a time, and the clamping cylinder lifts one sagger 11 at a time, stacking them one by one. The sagger 11 lifted by the lifting motor is lifted one by one, thus completing the stacking of multiple sagger 11. The stacking order is top layer first, then bottom layer.

[0052] Reference Figure 2Initially, there are no crucibles 11 on the second conveyor roller 200. The first conveyor roller 100 transports a set of overlapping crucibles 11 to the second conveyor roller 200 to the right. The second conveyor roller 200 then transports the overlapping crucibles 11 to the dismantling station 210 to the right. It is important to note that the second conveyor roller 200 can only dismantle one set of overlapping crucibles 11 at a time. Therefore, the first conveyor roller 100 transports one set of overlapping crucibles 11 to the second conveyor roller 200 at a time. After the second conveyor roller 200 has completed dismantling and is being transported downstream, the first conveyor roller 100 transports another set of overlapping crucibles 11 to the second conveyor roller 200. After reaching the dismantling station 210, the first lifting device 230 and the first supporting device 240 dismantle the three crucibles 11 in the order of bottom layer first, then top layer. During the disassembly process, the second conveyor roller 200 transports the contents to the left. Each time a sagger 11 is disassembled, it is transported to the left. After the sagger 11 is in place, the next sagger 11 is disassembled, and so on, until all three saggers 11 are disassembled. Because the second conveyor roller 200 transports the contents from downstream to upstream during disassembly (i.e., from right to left), the three disassembled saggers 11 are, from left to right, the lower sagger 11, the middle sagger 11, and the upper sagger 11. The second conveyor roller 200 transports the saggers 11 downstream in the order of lower sagger 11, middle sagger 11, and upper sagger 11. When stacking the saggers, the saggers 11 located downstream are stacked first, i.e., the upper sagger 11, then the middle sagger 11, then the lower sagger 11, stacking from the top to the bottom. After stacking, the saggers 11 are arranged from top to bottom as upper, middle, and lower saggers, which is consistent with the initial order of upper, middle, and lower saggers 11. This ensures that the stacking order remains consistent and prevents sagger sticking.

[0053] After the second conveyor roller 200 transports the overlapping saggers 11 to the disassembly station 210, the second conveyor roller 200 disassembles the saggers 11 from the bottom layer to the top layer and then transports them in the reverse direction. The bottom layer is located upstream of the top layer. After disassembly, the disassembled saggers 11 are transported together in the forward direction, with the bottom layer located upstream and the top layer located downstream. When stacking saggers in the future, the top layer is stacked first, and then the bottom layer is stacked below the top layer in sequence. After stacking, the top sagger 11 is still located on the top layer, maintaining the previous stacking order.

[0054] Reference Figure 1 and Figure 2 In this embodiment, the second conveyor roller 200 includes at least two roller sections arranged sequentially from upstream to downstream. Each roller section is controlled by a motor for transmission, and all roller sections are transmitted synchronously or stopped.

[0055] The second conveyor roller 200 can be composed of one, two, or more roller segments arranged sequentially, so that the specific number of roller segments can be selected according to the site or cost. Figure 2In this system, the second conveyor roller conveyor 200 comprises two roller conveyor sections. Regardless of the number of roller conveyor sections, they move synchronously along the upstream to downstream direction or along the downstream to upstream direction.

[0056] In this embodiment, the crucible circulation line conveying system further includes at least two positioning photoelectric sensors 220. The at least two positioning photoelectric sensors 220 are sequentially and spaced apart on the second conveying roller conveyor 200 in the direction from upstream to downstream. The at least two positioning photoelectric sensors 220 are used to correspond one-to-one with the position of the crucible 11 on the innermost downstream side of the second conveying roller conveyor 200. Each positioning photoelectric sensor 220 is used to detect the crucible 11 at the corresponding position. The second conveying roller conveyor 200 is used to stop after the positioning photoelectric sensor 220 detects the crucible 11 at the corresponding position. Then, the first lifting device 230 and the first lifting device 240 are activated to place a crucible 11 onto the second conveying roller conveyor 200.

[0057] At least two photoelectric sensors 220 are arranged sequentially from upstream to downstream as a first sensor and a second sensor, respectively, with the first sensor and the second sensor corresponding to the bottom to top of the sagger 11.

[0058] Reference Figure 2 The second conveyor roller 200, after disassembly, consists of a lower saucer 11, a middle saucer 11, and an upper saucer 11 from left to right. A position photoelectric sensor 220 is installed at the position of the lower saucer 11, and a corresponding position photoelectric sensor 220 is installed at the position of the middle saucer 11. Except for the last saucer 11 to be disassembled, all other disassembled saucers 11 require a corresponding position photoelectric sensor 220. This is because when the lower saucer 11 is detected to be in position, the second conveyor roller 200 stops, and the middle saucer 11 is disassembled and then conveyed to its corresponding position; after the middle saucer 11 is detected to be in position, the second conveyor roller 200 stops, and the upper saucer 11 is disassembled. Since the upper saucer 11 is the last saucer 11, it does not need to move further to the left; it is directly conveyed to the right along with the disassembled saucers 11. Therefore, compared to the number of disassembled saucers 11, one less position photoelectric sensor 220 is required.

[0059] When a sagger 11 is disassembled, the second conveyor roller 200 needs to move to the left by one position of sagger 11. The last disassembled sagger 11 does not need to be moved to the left by one position of sagger 11. The positioning photoelectric sensor 220 can control the movement frequency of the second conveyor roller 200, the first lifting device 230 and the first lifting device 240.

[0060] Continue to refer to Figure 2In this embodiment, the crucible circulation line conveying system also includes a crucible dismantling photoelectric sensor 300. The crucible dismantling photoelectric sensor 300 is set at the dismantling station 210 at the downstream end of the second conveying roller conveyor 200. The crucible dismantling photoelectric sensor 300 is used to detect the crucible 11 at the dismantling station 210. The second conveying roller conveyor 200 is used to stop when the crucible dismantling photoelectric sensor 300 detects the crucible 11. Then, the first lifting device 230 and the first lifting device 240 are activated to place a crucible 11 onto the second conveying roller conveyor 200.

[0061] The first conveyor roller 100 transports a set of overlapping crucibles 11 to the second conveyor roller 200. After the second conveyor roller 200 transports the overlapping crucibles 11 to the dismantling station 210, the dismantling photoelectric sensor 300 detects the crucibles 11, then stops the second conveyor roller 200 and starts the first lifting device 230 and the first lifting device 240 to begin dismantling. When one crucible is dismantled, the second conveyor roller 200 moves to the left by one position of crucible 11, and the above dismantling process is repeated.

[0062] Reference Figure 1 and Figure 2 In this embodiment, the dismantling photoelectric sensor 300 includes an upper photoelectric sensor 310 and a lower photoelectric sensor 320. The upper photoelectric sensor 310 is disposed above the lower photoelectric sensor 320. The lower photoelectric sensor 320 is used to detect the position of the bottommost crucible 11, and the upper photoelectric sensor 310 is used to detect the position of the adjacent crucible 11 above the bottommost crucible 11. The first lifting device 240 is activated when the upper photoelectric sensor 310 detects the crucible 11. The second conveying roller 200 is stopped when the upper photoelectric sensor 310 and the lower photoelectric sensor 320 detect that the crucible 11 has moved to the dismantling station 210. The second conveying roller 200 is also stopped when the upper photoelectric sensor 310 does not detect the crucible 11.

[0063] When the overlapping crucible 11 moves to the disassembly station 210, both the upper photoelectric sensor 310 and the lower photoelectric sensor 320 detect the crucible 11. This indicates that the crucible 11 has moved into place, and the first lifting device 230 and the first lifting device 240 are activated to begin disassembly.

[0064] During the disassembly process, the three crucibles 11 (upper, middle, and lower) are moved downwards in sequence. When the upper crucible 11 is located on the second conveyor roller 200, the upper photoelectric sensor 310 cannot detect the crucible 11, indicating that the disassembly is complete. If the upper photoelectric sensor 310 can still detect the crucible 11 at this time, it indicates that the system has malfunctioned and an alarm will be triggered.

[0065] The upper photoelectric sensor 310 can also be used to determine that after the sacrificial vessel 11 is in place, the first lifting device 240 is activated to lift and fix the sacrificial vessel 11.

[0066] In this embodiment, the crucible circulation line conveying system further includes a first blocking cylinder 250; the first blocking cylinder 250 is fixed downstream of the disassembly station 210, and the first blocking cylinder 250 is used to stop the crucible 11 that has moved to the disassembly station 210.

[0067] The overlapping crucibles 11 are moved to the disassembly station 210. The first blocking cylinder 250 can block the overlapping crucibles 11 to prevent them from being moved out of the disassembly station 210.

[0068] Reference Figure 1 and Figure 2 In this embodiment, the crucible circulation line conveying system further includes a preparatory photoelectric sensor 120; the preparatory photoelectric sensor 120 is disposed at a preparatory station 110 at the downstream end of the first conveying roller conveyor 100, and the preparatory photoelectric sensor 120 is used to detect the position of a group of multi-layered overlapping crucibles 11; the first conveying roller conveyor 100 is used to convey downstream when the preparatory photoelectric sensor 120 detects the crucible 11 and the crucible removal photoelectric sensor 300 detects that it is empty.

[0069] Multiple sets of overlapping crucibles 11 are sequentially conveyed to the preparation station 110 by the first conveyor roller 100. At this time, the preparation photoelectric sensor 120 detects the crucibles 11. If there are no crucibles 11 on the second conveyor roller 200, the first conveyor roller 100 conveys the crucibles 11 to the second conveyor roller 200. If there are crucibles 11 on the second conveyor roller 200, the first conveyor roller 100 stops.

[0070] Whether there is a crucible 11 on the second conveyor roller 200 can be determined by the detection of the positioning photoelectric sensor 220 and the crucible removal photoelectric sensor 300. If neither the positioning photoelectric sensor 220 nor the crucible removal photoelectric sensor 300 can detect the crucible 11, it means that there is no crucible 11 on the second conveyor roller 200.

[0071] Reference Figure 3 , Figure 4 and Figure 6In this embodiment, the crucible circulation line conveying system further includes a third conveying roller conveyor 400, a fourth conveying roller conveyor 500, a second lifting device 540, and a second lifting device 550. The second conveying roller conveyor 200, the third conveying roller conveyor 400, and the fourth conveying roller conveyor 500 are arranged sequentially. A combination station 530 is provided at the downstream end of the fourth conveying roller conveyor 500. The second lifting device 540 and the second lifting device 550 are arranged at the combination station 530. The third conveying roller conveyor 400 is used to convey a set of unfolded crucibles 11 to the fourth conveying roller conveyor 500. The fourth conveying roller conveyor 500 is used to convey the unfolded crucibles 11 sequentially to the combination station 530. The second lifting device 540 is used to lift the crucibles 11 conveyed to the combination station 530 to a preset position and be lifted and fixed by the second lifting device 550 until the set of unfolded crucibles 11 are restored to an overlapping state, and then conveyed downstream by the fourth conveying roller conveyor 500.

[0072] After being disassembled, the casket 11 from the second conveyor roller conveyor 200 is conveyed to the third conveyor roller conveyor 400, and then to the fourth conveyor roller conveyor 500. The third and fourth conveyor roller conveyors 400 and 500 can share a single conveyor roller conveyor. After being conveyed to the assembly station 530, it is then transported by the second lifting device 540 and the second lifting device 550 according to… Figure 6 The steps shown complete the overlap.

[0073] A second blocking cylinder 560 is provided downstream of the combined station 530 of the fourth conveyor roller 500. The second blocking cylinder 560 is used to stop the movement of the sagger 11.

[0074] Reference Figure 3 and Figure 4 In this embodiment, the crucible circulation conveyor system further includes a notch photoelectric sensor 520 and an alarm; a judgment station 510 is set at the downstream end of the fourth conveyor roller 500, and a combination station 530 is located downstream of the judgment station 510; the notch photoelectric sensor 520 is set at the judgment station 510 and is used to detect the notch condition of the crucible 11 conveyed to the judgment station 510; the alarm is used to sound an alarm if the notch condition of the crucible 11 detected by the notch photoelectric sensor 520 does not meet the preset condition; the fourth conveyor roller 500 is used to transmit to the combination station 530 if the notch condition of the crucible 11 detected by the notch photoelectric sensor 520 meets the preset condition. The combination station 530 is equipped with a combination photoelectric sensor to detect whether the crucible 11 has moved to the combination station 530.

[0075] Before the saggers 11 are stacked, the notch / groove arrangement is checked to ensure that the stacking order from top to bottom is: upper sagger 11 with a flat groove, middle sagger 11 with a notch, and lower sagger 11 with a notch. This is mainly achieved using a photoelectric sensor 520 for the flat groove / groove arrangement. If the laser can pass through the notch, it indicates that the sagger 11 has a notch; if it cannot, it indicates that the sagger 11 has a flat groove. If the corresponding stacked saggers 11 are incorrect, an alarm is triggered.

[0076] Embodiments of the present invention also provide a method for conveying a crucible circulation line, implemented using a crucible circulation line conveying system, the method comprising:

[0077] Obtain the first position signal of a set of multi-layered overlapping crucibles 11 arriving at the disassembly station 210;

[0078] According to the first position signal, the first lifting device 240 is controlled to lift the saucers 11 above the bottommost saucer 11, and the first lifting device 230 lowers the bottommost saucer 11 onto the second conveyor roller 200. The second conveyor roller 200 conveys the lowered saucers 11 upstream until a set of multi-layered overlapping saucers 11 unfolds sequentially from the bottommost to the topmost saucers 11 along the upstream to downstream direction on the second conveyor roller 200. The second conveyor roller 200 is then controlled to transport the unfolded saucers 11 downstream.

[0079] Reference Figure 7 , Figure 7 The disassembly process is illustrated. The preparatory photoelectric sensor 120 detects that the crucible 11 has arrived at the preparatory station 110—the arrival photoelectric sensor 220 and the disassembly photoelectric sensor 300 detect no signals (if the crucible 11 is detected, then wait)—the second conveyor roller 200 starts transporting from upstream to downstream—the disassembly photoelectric sensor 300 detects the crucible 11, and the second conveyor roller 200 stops (if not detected, then wait)—the first lifting device 230 rises—the first lifting device 240 lifts—the first lifting device 230 descends—the second conveyor roller 200 transports from downstream to upstream—the first sensor detects the crucible 11, and the second conveyor roller 200 stops—the first lifting device 230 rises—the first lifting device 240... Release 240—First lifting device 230 descends—Upper photoelectric sensor 310 detects the presence of crucible 11, first lifting device 240 lifts it—First lifting device 230 descends—Second conveyor roller 200 transports from downstream to upstream—Second sensor detects crucible 11, second conveyor roller 200 stops—First lifting device 230 rises—First lifting device 240 is released—First lifting device 230 descends—Upper photoelectric sensor 310 detects no crucible 11 (if present, an error is reported)—Disassembly complete—Second conveyor roller 200 transports from upstream to downstream—Position photoelectric sensor 220 and crucible removal photoelectric sensor 300 detect no signal—End.

[0080] Reference Figure 8 When the photoelectric sensor is aligned with the notched crucible 11, it returns 0 (no signal); when the photoelectric sensor is aligned with the flat-mouth crucible 11, it returns 1 (signal present). The flat-mouth notch photoelectric sensor 520 detects that the first crucible 11 at judgment station 510 is flat (an alarm is triggered if it is notched)—the fourth conveyor roller 500 is started. The combined photoelectric sensor detects that crucible 11 has moved to the combined station 530 (if not detected, it waits). The fourth conveyor roller 500 stops—the second lifting device 540 rises—the second lifting device 550 lifts—the second lifting device 540 descends and resets, the count is 1—the flat-mouth notch photoelectric sensor 520 detects that the second crucible 11 at judgment station 510 is notched (an alarm is triggered if it is not notched)—the fourth conveyor roller 500 is started. The combined photoelectric sensor detects that crucible 11 has moved to the combined station 530 (if not detected, it waits). The fourth conveyor roller... Conveyor 500 stops—Second lifting device 540 rises—Second lifting device 550 releases—Second lifting device 540 rises—Second lifting device 550 lifts—Second lifting device 540 descends and resets, count is 2—Plain notch photoelectric sensor 520 detects that the third crock 11 at the judgment station 510 is notched (if it is not notched, an alarm is triggered)—Fourth conveyor roller conveyor 500 starts, combined photoelectric sensor detects that crock 11 has moved to combined station 530 (if not detected, wait), fourth conveyor roller conveyor 500 stops—Second lifting device 540 rises—Second lifting device 550 releases—Second lifting device 540 descends and resets, count is 3—Fourth conveyor roller conveyor 500 conveys the overlapping crock 11 downstream—End.

[0081] Figure 7 and Figure 8 All of these involve disassembling and stacking a single set of saggers 11. By repeating the above process, the disassembly and stacking of multiple sets of saggers 11 can be completed.

[0082] The sagger circulation line conveyor system provided in this embodiment has at least the following advantages:

[0083] After the second conveyor roller 200 transports the overlapping saggers 11 to the disassembly station 210, the second conveyor roller 200 disassembles the saggers 11 from the bottom to the top and then transports them in the reverse direction. After disassembly, the disassembled saggers 11 are transported together in the forward direction, with the bottom layer located upstream and the top layer located downstream. When stacking the saggers in the future, the top layer is stacked first, and then the bottom layer is stacked below the top layer in sequence. After stacking, the top sagger 11 is still located on the top layer, maintaining the previous stacking order, which completely solves the defect of sagger 11 sticking together.

[0084] Before stacking the kilns, the order of stacking can be checked again by inspecting the flat rim and notch of the kiln 11. This enhances the error correction capability of the equipment and can detect whether the stacking order of the kiln 11 is correct, thereby ensuring product quality.

[0085] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
