[0002] During the production of developing rollers, they are temporarily stored and rotated using turntables. Upon warehousing and shipment, the developing rollers need to be packaged for storage and transportation. Currently, packaging is usually done manually. The developing rollers are first placed on pallets, and then the pallets and the rollers on them are placed into the storage bin. This process is labor-intensive, inefficient, and costly, and it easily leads to problems such as improper placement of developing rollers, insufficient pallets in the storage bin, or insufficient developing rollers.

The handling device transports the developing rollers on the turnover tray to the pallet and the pallets on the pallet to the storage slot of the material box at the packaging station, until all the pallets on the pallet are placed in the storage slot of the material box, completing the packaging of one box of developing rollers. This is highly efficient, replaces manual labor, and reduces labor costs. The pallet serves to position and protect multiple developing rollers, and multiple sets can be stacked together, facilitating the storage and transportation of developing rollers through sets.

[0018] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0019] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0020] Reference Figures 1 to 3This invention discloses a developing roller packaging line, including a turnover tray conveyor belt 100, a set conveyor belt 200, a set 300, a lifting device 400, a lifting device 500, and a handling device 600. The turnover tray conveyor belt 100 is used to transport turnover trays 10, which carry developing rollers to be packaged. The turnover trays 10 are turnover jigs used in the production of developing rollers. The turnover trays 10 are placed at the beginning of the turnover tray conveyor belt 100, and the turnover trays 10 are driven to move along the conveying direction of the turnover tray conveyor belt 100 (from left to right). The turnover trays 10 move from the beginning to the end of the turnover tray conveyor belt 100.

[0021] The kit 300 includes a material bin 310 and multiple sets of trays 320. Each set of trays 320 includes multiple stacked trays 320. The trays 320 are used to limit the movement of multiple developing rollers. The material bin 310 has a receiving groove in which the multiple sets of trays 320 are received. The bottom wall of the material bin 310 has multiple sets of clearance holes 311, which are all connected to the receiving groove and are respectively aligned with the multiple sets of trays 320. Initially, multiple empty trays 320 are stacked in the receiving groove of the material bin 310 to form a set of trays 320. The receiving groove of the material bin 310 contains multiple sets of trays 320, and at this time, the multiple sets of clearance holes 311 are respectively aligned with the multiple sets of trays 320.

[0022] The set conveyor belt 200 is used to transport the set 300. The set conveyor belt 200 has a pallet unloading station and a packaging station along the conveying direction of the set conveyor belt 200 (from left to right). The set 300 is placed at the first end of the set conveyor belt 200. The set conveyor belt 200 drives the set 300 to move along the conveying direction of the set conveyor belt 200. The set 300 moves from the first end of the set conveyor belt 200 to the end of the set conveyor belt 200, so that the set 300 can pass through the pallet unloading station and the packaging station in sequence.

[0023] Reference Figure 2 and Figure 3 The lifting device 400 includes multiple sets of top rods 410 arranged relative to the pallet unloading station. The top rods 410 can pass through the clearance hole 311 from bottom to top and can exit the clearance hole 311 from top to bottom. When the set conveyor belt 200 transports the set 300 to the pallet unloading station, the set 300 stops moving and the clearance hole 311 of the material box 310 is directly opposite the top rod 410. The top rod 410 passes through the clearance hole 311 from bottom to top, and the top rod 410 can lift the pallet 320 in the storage slot. The pallet 320 will move above the material box 310.

[0024] Reference Figure 2 and Figure 3The lifting device 500 includes a pallet 510 positioned relative to the pallet unloading station. The pallet 510 can move above the assembly conveyor belt 200 and lift the pallet 320 lifted by the push rod 410. Before the push rod 410 passes through the clearance hole 311 from bottom to top, the pallet 510 moves outside the assembly conveyor belt 200 to prevent the pallet 510 from blocking the pallet 320 inside the hopper 310 from rising. When the push rod 410 lifts the pallet 320 inside the hopper 310 to the assembly conveyor belt 200 / hopper 310... When the pallet 510 is above the set conveyor belt 200, part of the structure of the pallet 510 is directly below the pallet 320. Then the push rod 410 moves from top to bottom, and the pallet 320 on the push rod 410 abuts against the pallet 510 and exits the clearance hole 311, thus transferring the pallet 320 onto the pallet 510. Then the set conveyor belt 200 continues to transport the material box 310. The set conveyor belt 200 can transport the material box 310 to the packaging station, where the material box 310 is positioned.

[0025] Understandably, the pallet 510 moves horizontally and is higher than the hopper 310 on the conveyor belt 200 to prevent the pallet 510 from obstructing the movement of the hopper 310.

[0026] The conveying device 600 is used to move the developing roller on the turnover tray 10 to the tray 320 and to move the tray 320 on the pallet 510 to the storage slot of the material box 310 at the packaging station.

[0027] Empty pallets 320 can be pre-assembled into multiple sets of pallets 320 and placed in the storage slot of the material box 310 to form a set 300. The set 300 is then placed at the beginning of the set conveyor belt 200, which transports the set 300 to the pallet unloading station. The lifting device 400's push rod 410 extends into the storage slot to lift the pallet 320 from the storage slot. The lifting device 500's pallet plate 510 lifts the pallet 320, and then the push rod 410... After exiting the storage slot and clearance hole 311, the assembly conveyor belt 200 transports the material box 310 to the packaging station. The handling device 600 moves the developing rollers on the turnover tray 10 to the pallet 320 and the pallets 320 on the pallet 510 to the storage slot of the material box 310 at the packaging station, until all the pallets 320 on the pallet 510 are accommodated in the storage slot of the material box 310, completing the packaging of one box of developing rollers. This process is highly efficient, replacing manual labor and reducing labor costs. The pallet 320 serves to position and protect multiple developing rollers, and multiple sets 300 can be stacked together, facilitating the storage and transportation of developing rollers through the sets 300.

[0028] The developing roller packaging line replaces manual packaging of developing rollers, reducing the workload of workers, increasing efficiency, reducing error rate, and lowering labor costs. The material box 310 and pallet 320 are loaded into the first end of the set conveyor belt 200 in the form of a set 300. The material box 310 and pallet 320 are matched in advance to achieve convenient and quick loading of the material box 310 and pallet 320. Through the cooperation of the lifting device 400, the lifting device 500 and the handling device 600, the developing roller is loaded into the pallet 320 and the pallet 320 is put back into the material box 310, resulting in a set 300 containing the developing roller.

[0029] In some embodiments, the number of pallets 510 is at least one pair, and the pair of pallets 510 can be close to each other above the set conveyor belt 200. The pair of pallets 510 can support both ends of the pallet 320, so that the pallet 320 is balanced by force and maintains the stability of the pallet 320.

[0030] Reference Figure 2 or Figure 3 The lifting device 500 also includes a first horizontal drive mechanism 520. The number of first horizontal drive mechanisms 520 is equal to the number of pallets 510. The output end of the first horizontal drive mechanism 520 is connected to the pallet 510. The first horizontal drive mechanism 520 is used to drive the pallet 510 to move, so that the pallet 510 moves above or away from the set conveyor belt 200. When the pallet 510 moves above the set conveyor belt 200, the pallet 320 can fall on the pallet 510. When the pallet 510 avoids the set conveyor belt 200, the pallet 510 is prevented from blocking the rise of the pallet 320.

[0031] The driving direction of the first horizontal drive mechanism 520 is parallel to the conveying surface of the set conveyor belt 200, and the driving direction of the first horizontal drive mechanism 520 is perpendicular to the conveying direction of the set conveyor belt 200. Two first horizontal drive mechanisms 520 are respectively located on both sides of the set conveyor belt 200, with their output ends facing each other. The first horizontal drive mechanism 520 is a first cylinder.

[0032] In some embodiments, the turntable conveyor belt 100 is provided with a developing roller inspection station and a developing roller loading station along the conveying direction of the turntable conveyor belt 100, as shown in the figure. Figure 1A photographic inspection mechanism 110 is provided at the developing roller inspection station. When the turntable conveyor belt 100 transports the turntable 10 carrying the developing roller to the developing roller inspection station, the photographic inspection mechanism 110 is used to take pictures of the developing roller on the turntable 10 to detect the model and posture of the developing roller. When the model and posture of the developing roller are correct, the turntable conveyor belt 100 transports the turntable 10 from the developing roller inspection station to the developing roller loading station. The developing roller loading station is used to position the turntable 10 so that the conveying device 600 can clamp the developing roller on the turntable 10.

[0033] Reference Figure 1 A first photographic positioning mechanism 120 is provided at the developing roller loading station. This mechanism is used to photograph and position the turntable 10 and the developing roller on it at the developing roller loading station, ensuring that the conveying device 600 can accurately clamp the developing roller on the turntable 10. A first positioning baffle is provided at the developing roller inspection station. This baffle can move to the conveying surface of the turntable conveyor belt 100 to prevent the turntable 10 from moving further, thus positioning the turntable 10 at the developing roller inspection station so that the photographic inspection mechanism 110 can detect the model and orientation of the developing roller. A second positioning baffle is provided at the developing roller loading station. This baffle can move to the conveying surface of the turntable conveyor belt 100 to prevent the turntable 10 from moving further, thus positioning the turntable 10 at the developing roller loading station.

[0034] A third positioning baffle is provided at the pallet unloading station. This third positioning baffle can move to the conveying surface of the assembly conveyor belt 200 to prevent the assembly 300 from moving further, thereby positioning the assembly 300 at the pallet unloading station, so that the top rod 410 is directly below the clearance hole 311. A fourth positioning baffle and a second photo positioning mechanism 210 are provided at the packaging station (e.g., Figure 1 As shown), the fourth positioning baffle can move to the conveying surface of the set conveyor belt 200 to block the set 300 from moving further, thereby positioning the set 300 at the packaging station, so that the lifting device 500 can accurately place the pallet 320 into the material box 310 at the packaging station. The second photo positioning mechanism 210 is used to take a photo of the material box 310 at the packaging station to ensure that the handling device 600 can accurately place the pallet 320 into the material box 310.

[0035] The turnover tray conveyor belt 100 and the set conveyor belt 200 are arranged side by side, and their conveying directions are parallel to each other. The turnover tray conveyor belt 100 and the set conveyor belt 200 have the same structure.

[0036] Reference Figure 1 or Figure 2In some embodiments, the conveyor belt 200 includes two parallel chains in a loop. The two chains rotate synchronously, and multiple support seats are evenly distributed on the outer side of the chains. The support seats of the two chains are used to support the two ends of the material box 310, so that the two ends of the material box 310 are balanced. The two chains drive the material box 310 to move, thereby conveying the set 300. A clearance space is formed between the two chains, and the top rod 410 is set in the area between the two chains.

[0037] Understandably, the support base is U-shaped, and its two ends are hinged to the pins of the chain, allowing the support base to rotate relative to the chain to a certain extent. When a part of the chain is in a straight line, the outer surface of the support base translates to a part of the chain, and the outer surface of the support base is used to abut against the outer surface of the bottom wall of the material box 310.

[0038] The conveyor belt 200 also includes a rotary drive mechanism, two drive sprockets and two driven sprockets. The two drive sprockets and two driven sprockets are distributed at four corners. The two drive sprockets are connected by a transmission rod. One chain is wound around one drive sprocket and one driven sprocket, and the other chain is wound around another drive sprocket and another driven sprocket. The output end of the rotary drive mechanism is connected to one of the drive sprockets. The rotary drive mechanism can drive the two chains to rotate synchronously.

[0039] Reference Figure 3 The lifting device 400 also includes a first lifting drive mechanism 420, which is disposed between two chains. The output end of the first lifting drive mechanism 420 faces upward and is connected to the top rod 410 through an adapter plate. The first lifting drive mechanism 420 drives the top rod 410 to rise and fall. The upper end of the top rod 410 is tapered so that the upper end of the top rod 410 can be inserted into the clearance hole 311.

[0040] Two sets of push rods are connected to the adapter plate. One set of push rods includes four push rods 410 distributed at four corners. The bottom wall of the material box 310 has two sets of clearance holes 311. One set of clearance holes 311 includes four clearance holes 311 distributed at four corners. The four push rods 410 of the set of push rods are respectively arranged opposite to the four clearance holes 311 of the set of clearance holes 311, so that the four push rods 410 of the set of push rods can be inserted into the four clearance holes 311 of the set of clearance holes 311 respectively. The upper ends of the four push rods 410 of the set of push rods can respectively abut against the four corners of the tray 320.

[0041] Reference Figure 1 and Figure 4In some embodiments, the handling device 600 includes a robot 610, a developing roller clamp 620, and a pallet clamp 630. The developing roller clamp 620 and the pallet clamp 630 are both connected to the output end of the robot 610. The robot 610 is positioned between the turntable conveyor belt 100 and the set conveyor belt 200. The robot 610 can drive the developing roller clamp 620 and the pallet clamp 630 to move in the front-back, left-right, and up-down directions, that is, the robot 610 can drive the developing roller clamp 620 and the pallet clamp 630 to move in three-dimensional space.

[0042] The robot 610 drives the developing roller clamp 620 to move between the turntable 10 on the turntable conveyor belt 100 and the pallet 320 in the hopper 310 at the packaging station, or the robot 610 drives the developing roller clamp 620 to move between the turntable 10 on the turntable conveyor belt 10 and the pallet 320 on the pallet 510, so that the developing roller clamp 620 can transport the developing roller on the turntable 10 to the pallet 320.

[0043] The robot 610 also drives the pallet gripper 630 to move between the pallet 510 and the hopper 310 at the packaging station to transport the pallet 320 on the pallet 510 to the storage slot of the hopper 310, and finally complete the transfer of the developing roller from the turntable 10 to the pallet 320 and the transfer of the pallet 320 to the hopper 310, thereby completing the packaging of the developing roller.

[0044] The robot 610 drives the developing roller clamp 620 and the tray clamp 630 with high moving precision and speed, enabling precise and rapid handling of the developing rollers and tray 320. The developing roller clamp 620 can simultaneously clamp multiple developing rollers on the turnover tray 10, improving the efficiency of developing roller transfer. As can be seen, the multiple developing rollers on the turnover tray 10 are arranged side-by-side, and when placed on the tray 320, they are also arranged side-by-side. The developing roller clamp 620 only needs to simultaneously clamp and release multiple developing rollers, without needing to adjust the relative position and orientation of the multiple developing rollers.

[0045] It is conceivable that, for different models of material bins 310, the spacing between two adjacent placement trays 320 in the storage slot of different models of material bins 310 is different. In order to enable the developing roller clamp 620 to accurately place two sets of developing rollers into the two adjacent placement trays 320 in the material bin 310 at one time, in some embodiments, the number of developing roller clamps 620 is set to two sets. One set of developing roller clamps 620 is used to clamp one set of developing rollers, and the spacing between the two sets of developing roller clamps 620 can be adjusted to clamp two sets of developing rollers with different intervals, so that the two sets of developing roller clamps 620 can match the positions of the two adjacent placement trays 320 respectively. The two sets of developing roller clamps 620 can simultaneously clamp two sets of developing rollers and place the two sets of developing rollers into the two adjacent placement trays 320 in the material bin 310 at the same time.

[0046] Reference Figure 4 In some embodiments, the output end of robot 610 is connected to adapter 611, see reference Figure 5 The developing roller clamp 620 includes a sliding plate 621 and two developing roller clamping mechanisms, both connected to the sliding plate 621. The sliding plate 621 is slidably connected to the adapter frame 611, and the developing roller clamping mechanisms are used to clamp the developing rollers. The robot 610 is connected to the sliding plate 621 through the adapter frame 611. The sliding plate 621 can slide on the adapter frame 611, thereby adjusting the distance between the two sets of developing roller clamps 620.

[0047] Specifically, the sliding plate 621 is connected to the adapter frame 611 via a first sliding mechanism, which guides the movement of the sliding plate 621. The adapter frame 611 is equipped with a linear drive mechanism, the output of which is connected to the sliding plate 621. The linear drive mechanism drives the sliding plate 621 to move on the adapter frame 611, thereby adjusting the distance between the two sets of developing roller clamps 620.

[0048] The developing roller clamping mechanism includes two clamping plates 622. Each clamping plate 622 includes multiple clamping portions 6221 distributed in the left-right direction. The two clamping plates 622 can open and close to allow the clamping portions 6221 of the two clamping plates 622 to release or clamp the end of the developing roller. The multiple clamping portions 6221 of the two clamping plates 622 cooperate to form multiple sets of clamping structures. The multiple sets of clamping structures are arranged side by side in the left-right direction. The multiple sets of clamping structures can simultaneously clamp and release multiple developing roller ends that are arranged side by side in the conveying direction on the turntable 10.

[0049] The developing roller clamp 620 also includes a first clamping cylinder, which is connected to the sliding plate 621. The two output ends of the first clamping cylinder are respectively connected to two clamping plates 622. The first clamping cylinder drives the two clamping plates 622 to move relative to each other, that is, drives the two clamping plates 622 to open and close, so that multiple clamping structures open or close at the same time, so as to simultaneously release the end of the developing roller or simultaneously clamp the end of the developing roller.

[0050] Two clamping plates 622 are respectively connected to the sliding plate 621 through two second sliding mechanisms. The second sliding mechanisms guide the movement of the clamping plates 622, ensuring that the two clamping plates 622 move along a predetermined trajectory, thereby ensuring that multiple clamping structures can open or close simultaneously when the two clamping plates 622 move relative to each other.

[0051] In one embodiment, the clamping plate 622 and the clamping part 6221 may be an integrally formed structure. In another embodiment, the clamping part 6221 is detachably connected to the clamping plate 622, and the position of the clamping part 6221 on the clamping plate 622 can be adjusted, thereby adjusting the interval between two adjacent sets of clamping structures, so that the developing roller clamp 620 is suitable for clamping developing rollers with different intervals.

[0052] It is important to understand that when the turntable 10 carries the developing rollers to be packaged, multiple developing rollers (a group) are arranged side-by-side at equal intervals L2 along the conveying direction (from left to right) of the turntable conveyor belt 100, with the length direction of the developing rollers perpendicular to the conveying direction of the turntable conveyor belt 100. When the multiple developing rollers (a group) are placed on the tray 320, they are arranged side-by-side at equal intervals L1 along the conveying direction (from left to right) of the set conveyor belt 200, with the length direction of the developing rollers perpendicular to the conveying direction of the set conveyor belt 200. When L1 equals L2, the position of the clamping portion 6221 on the clamping plate 622 remains unchanged, and the two developing roller clamping mechanisms can directly clamp a group of developing rollers on the turntable 10. Then, the group of developing rollers is installed or placed on the tray 320 at a spacing equal to that on the turntable 10. When L1 is not equal to L2, the spacing between two adjacent clamping portions 6221 on the clamping plate 622 of the developing roller clamping mechanism needs to be dynamically adjusted, as illustrated in the following embodiment.

[0053] Reference Figure 6 and Figure 7In some embodiments, multiple clamping parts 6221 are slidably connected to a clamping plate 622 in the left-right direction, so that all clamping parts 6221 can be adjusted in position on the clamping plate 622. The clamping plate 622 is connected to a lifting drive plate 623, and multiple wedge blocks 624 that can slide in the left-right direction are connected to the drive plate 623. One end of the wedge block 624 in the left-right direction is provided with an inclined surface 6241, which is used to abut against the end of the clamping part 6221 in the left-right direction to drive the clamping part 6221 to move in the left-right direction and form an equal distance L1 (e.g., Figure 6 The developing roller clamping mechanism also includes a plurality of first elastic elements 625, which are used to force a plurality of clamping parts 6221 to move in the left-right direction and form an equal spacing L2 (e.g., Figure 7 The distribution is such that L1 is greater than L2.

[0054] When the drive plate 623 descends, the wedge block 624 descends with the drive plate 623 and can move along the left and right directions on the drive plate 623. The wedge block 624 pushes one end of the clamping part 6221 along the left and right directions through the inclined surface 6241. Since the clamping part 6221 can only slide in the left and right directions, any two adjacent wedge blocks 624 and any two adjacent clamping parts 6221 will move away from each other, so that the multiple clamping parts 6221 form an equal spacing L1 distribution. Finally, the clamping parts 6221 of the two clamping plates 622 present an equal spacing L1 clamping state of the developing roller. At this time, the first elastic element 625 deforms to The drive plate 623 rises, and the wedge block 624 rises with the drive plate 623. The first elastic element 625 deforms in the opposite direction to release potential energy, so that any two adjacent clamping parts 6221 move closer to each other. The clamping parts 6221 drive any two adjacent wedge blocks 624 to move closer to each other through the inclined surface 6241, so that multiple clamping parts 6221 are distributed with equal spacing L2. Finally, the clamping parts 6221 of the two clamping plates 622 are in a state of equal spacing L2 clamping the developing roller, realizing the dynamic adjustment of the spacing between two adjacent clamping parts 6221 on the clamping plate 622 during the use of the developing roller clamping mechanism.

[0055] It is understood that one end of the clamping part 6221 in the left-right direction has a mating surface that cooperates with the inclined surface 6241, and the inclined surface 6241 and the mating surface are parallel to each other. On the same clamping plate 622, there are n clamping parts 6221 and n-1 first elastic members 625, with both ends of the first elastic members 625 connected to two adjacent clamping parts 6221 respectively. There are n-1 wedge blocks 624, and the developing roller clamping mechanism also includes n-1 second elastic members 627, with both ends of the second elastic members 627 connected to two adjacent wedge blocks 624 respectively. The drive plate 623 is provided with a guide hole that runs through the drive plate 623 in the vertical direction and is parallel to the horizontal direction in the length direction. The upper end of the wedge block 624 is connected to a vertical guide post 6242, which passes through the guide hole. The upper end of the guide post 6242 is threaded with a nut, which abuts against the upper surface of the drive plate 623, so that the wedge block 624 can slide and connect to the drive plate 623. The wedge block 624 moves on the drive plate 623 in the horizontal direction through the guide post 6242, and the wedge block 624 rises and falls synchronously with the drive plate 623.

[0056] Multiple clamping parts 6221 are connected to the clamping plate 622 via a third sliding mechanism. A limiting block is provided at one end of the clamping plate 622 along the left and right direction. The outermost clamping part 6221 abuts against the limiting block and is blocked from moving by the limiting block. Due to the setting of the limiting block, the other multiple clamping parts 6221 can only be evenly distributed with the limiting block as the starting point. That is, except for the clamping part 6221 abutting against the limiting block, the other multiple clamping parts 6221 can simultaneously move closer to or away from the outermost clamping part 6221 in one direction; or the outermost clamping part 6221 can be directly fixed on the clamping plate 622, thus eliminating the limiting block.

[0057] The clamping plate 622 is connected to two fourth lifting drive mechanisms 626. The output ends of the two fourth lifting drive mechanisms 626 are respectively connected to the two ends of the drive plate 623. The drive plate 623 is connected to the clamping plate 622 through two fourth sliding mechanisms. The fourth sliding mechanisms guide the lifting and lowering movement of the drive plate 623, ensuring that the two drive plates 623 move up and down along a predetermined trajectory and preventing the drive plate 623 from deviating in the left and right directions.

[0058] Reference Figure 4 In some embodiments, the output end of robot 610 is connected to adapter 611, see reference Figure 8The pallet clamp 630 includes two sliding plates 631 slidably connected to the adapter frame 611. The two sliding plates 631 can move away from or towards each other. A second lifting drive mechanism 632 is connected to each of the two sliding plates 631. A pallet clamping arm 633 is connected to the output end of each of the second lifting drive mechanisms 632. The two pallet clamping arms 633 are respectively used to clamp the two ends of the pallet 320. When the two sliding plates 631 move away from each other, the two pallet clamping arms 633 also move away from each other, allowing the two pallet clamping arms 633 to be positioned on the outer sides of the two ends of the pallet 320, meaning the pallet 320 is positioned between the two pallet clamping arms. The position of the clamping arms 633 is such that when the two slide plates 631 approach each other, the two pallet clamping arms 633 also approach each other, so that the two pallet clamping arms 633 can clamp the two ends of the pallet 320; the second lifting drive mechanism 632 can drive the pallet clamping arms 633 to rise and fall, so that the pallet clamping arms 633 can move from top to bottom to the outside of the pallet 320 or from bottom to top to a position higher than the pallet 320. When the two pallet clamping arms 633 clamp the two ends of the pallet 320, the second lifting drive mechanism 632 can drive the pallet clamping arms 633 to rise and fall to drive the pallet 320 to rise and fall.

[0059] Reference Figure 8 The pallet clamp 630 also includes a second clamping cylinder 634, which is connected to the adapter frame 611. The two output ends of the second clamping cylinder 634 are respectively connected to two slide plates 631, so that the two slide plates 631 can move away from each other or move closer to each other.

[0060] Reference Figure 1 In some embodiments, the developing roller packaging line also includes a turntable feeding device 700 and a turntable stacking device 800. The turntable feeding device 700 and the turntable stacking device 800 are respectively set at the beginning and end of the turntable conveyor belt 100. The turntable feeding device 700 is used to feed the turntable 10 carrying the developing roller to the beginning of the turntable conveyor belt 100. The turntable stacking device 800 is used to stack the turntable 10 whose developing roller has been removed. The turntable feeding device 700 replaces manual labor to feed multiple turntables 10 carrying developing rollers one by one to the beginning of the turntable conveyor belt 100. The turntable stacking device 800 replaces manual labor to stack multiple turntables 10 whose developing roller has been removed together, thereby freeing up labor and improving the feeding and unloading efficiency of the turntable 10.

[0061] Reference Figure 9In some embodiments, the turntable feeding device 700 includes a feeding conveyor belt 710, a second horizontal drive mechanism 720, a third lifting drive mechanism 730, and a turntable clamp 740. The feeding conveyor belt 710 is positioned at the beginning of the turntable conveyor belt 100 and is used to transport multiple sets of turntables 10. The turntable clamp 740 includes a bracket 741 and two turntable clamping arms 742. The two turntable clamping arms 742 are closably connected to the bracket 741 to clamp both ends of the turntable 10. Specifically, when the two turntable clamping arms 742 are separated, they can move to the outer sides of both ends of the turntable 10, and when they are closed, they can clamp both ends of the turntable 10.

[0062] The second horizontal drive mechanism 720 and the third lifting drive mechanism 730 are used to drive the support 741 to move in the horizontal and vertical directions, respectively, thereby driving the two turntable clamping arms 742 to move in the horizontal and vertical directions, so that the two turntable clamping arms 742 can transport the turntable 10 on the feeding conveyor belt 710 to the beginning of the turntable conveyor belt 100.

[0063] It is understood that the conveying direction of the feeding conveyor belt 710 and the conveying direction of the turnover conveyor belt 100 are perpendicular to each other. The beginning of the turnover conveyor belt 100 is close to the end of the feeding conveyor belt 710. The conveying directions of the feeding conveyor belt 710, the turnover conveyor belt 100, and the driving direction of the second horizontal drive mechanism 720 are all parallel to the horizontal plane. The two ends of the driving direction of the second horizontal drive mechanism 720 correspond to the beginning of the turnover conveyor belt 100 and the end of the feeding conveyor belt 710, respectively. The output end of the third lifting drive mechanism 730 is connected to the third lifting drive mechanism 730, and the output end of the third lifting drive mechanism 730 is connected to the bracket 741. The second horizontal drive mechanism 720 drives the third lifting drive mechanism 730 and the turnover tray clamp 740 to move between the beginning of the turnover tray conveyor belt 100 and the end of the feeding conveyor belt 710. The third lifting drive mechanism 730 drives the turnover tray clamp 740 to lift and lower, so that the turnover tray clamp 740 can transport multiple sets of turnover trays 10 on the end of the feeding conveyor belt 710 to the beginning of the turnover tray conveyor belt 100 one by one.

[0064] The structure of the turntable palletizing device 800 is the same as or similar to that of the turntable feeding device 700, and will not be described redundantly here. Hooks are provided on both sides of the two turntable clamping arms 742 facing each other. These hooks are used to hook onto the lower surface of the turntable 10, ensuring the reliability of the turntable clamping arms 742 in holding the turntable 10. The turntable clamping arms 742 are connected to two positioning blocks 743. The positioning blocks 743 have right-angled sides, and the turntable 10 also has four right-angled sides. When the two turntable clamping arms 742 approach each other, the four positioning blocks 743, totaling four right-angled sides, respectively abut against the four right-angled sides of the turntable 10, achieving positioning and clamping of the turntable 10 in a specific area by the turntable clamping arms 742. This ensures the accuracy of the turntable clamp 740 in holding the turntable 10, and thus ensures the accuracy of placing the turntable 10 at the beginning of the turntable conveyor belt 100.

[0065] When the package 300 is not packaged with a developing roller (initially), it is stacked on a pallet. After the package 300 is packaged with a developing roller, it also needs to be re-stacked on another pallet. The developing roller packaging line also includes a package feeding device and a package stacking device. The package feeding device and the package stacking device are respectively set at the beginning and end of the package conveyor belt 200. The package feeding device is used to feed the package 300 without developing rollers to the beginning of the package conveyor belt 200, that is, to feed the package 300 on the pallet one by one to the beginning of the package conveyor belt 200. The package stacking device is used to stack the package 300 with developing rollers packaged, that is, to stack the package 300 with developing rollers packaged at the end of the package conveyor belt 200 one by one on another pallet.

[0066] The first lifting drive mechanism 420 can be a lead screw or an electric actuator. The first horizontal drive mechanism 520, the linear drive mechanism, the second lifting drive mechanism 632, the second horizontal drive mechanism 720, the third lifting drive mechanism 730, and the fourth lifting drive mechanism 626 can all be cylinders.

[0067] Reference Figures 10 to 12 The upper surface of the tray 320 is provided with multiple parallel limiting grooves 321. The limiting grooves 321 are used to limit the developing rollers. Multiple developing rollers can be placed side by side in the multiple limiting grooves 321. The tray 320 plays the role of supporting and storing multiple developing rollers and can prevent the developing rollers from moving or shifting on the tray 320.

[0068] The tray 320 is provided with two first positioning protrusions 322 and two positioning grooves 323. The two first positioning protrusions 322 are used to cooperate with the two positioning grooves 323 of another tray 320 so that the two trays 320 are aligned vertically, ensuring that multiple trays 320 can be stacked together and aligned vertically. The projections of the multiple stacked trays 320 from top to bottom overlap, and the multiple trays 320 stacked together form a set of trays.

[0069] The bin 310 has a storage slot for storing the tray 320. The kit 300 also includes a foolproof slot 324 and a foolproof component 312. One of the foolproof slot 324 and the foolproof component 312 is disposed on the tray 320, and the other is disposed on the inner wall of the storage slot. The foolproof component 312 is used to extend into the foolproof slot 324 so that multiple trays 320 are stacked in the storage slot so that multiple trays 320 are positioned in a stacked state in the storage slot.

[0070] When placing the tray 320 into the storage slot, one method is to place multiple trays 320 sequentially into the storage slot, with the anti-misbehavior groove 324 or anti-misbehavior component 312 on the tray 320 engaging with the anti-misbehavior component 312 or anti-misbehavior groove 324 on the inner wall of the storage slot; another method is to first stack multiple trays 320 together, and then simultaneously place the stacked multiple trays 320 into the storage slot. When the multiple trays 320 are stacked vertically, the anti-misbehavior groove 324 or anti-misbehavior component 312 on the multiple trays 320 are aligned vertically. When simultaneously placing the stacked multiple trays 320 into the storage slot, the anti-misbehavior groove 324 or anti-misbehavior component 312 on the multiple trays 320 engage with the anti-misbehavior component 312 or anti-misbehavior groove 324 on the inner wall of the storage slot.

[0071] By using the anti-misalignment component 312 or anti-misalignment groove 324, and the cooperation of the first positioning protrusion 322 and positioning groove 323, multiple pallets 320 can be aligned vertically to form a set of pallets. Then, by using the anti-misalignment component 312 and anti-misalignment groove 324, multiple sets of pallets can be confined to the storage slot of the material box 310. The material box 310 serves to store multiple sets of pallets, preventing pallets 320 from being stacked out of place or from collapsing. This allows for the stacking of pallets 320 with a large number of layers. The material box 310 can also be stacked on a pallet to package a large number of pallets 320, so as to facilitate the stable turnover and transportation of the developing roller, and also to protect the developing roller.

[0072] In this embodiment, the tray 320 is provided with a foolproof groove 324, and the inner wall of the storage groove is provided with a foolproof member 312. The foolproof member 312 extends in the vertical direction and can extend into multiple foolproof grooves 324 on the same set of trays, so that the foolproof member 312 can position multiple stacked trays 320 in the storage groove. Specifically, the foolproof groove 324 is notched or recessed, and the foolproof groove 324 is formed on the front or rear face of the tray 320. A set of foolproof grooves includes two foolproof grooves 324. The foolproof member 312 is plate-shaped and can be inserted into or extended into the foolproof groove 324.

[0073] Specifically, the first positioning protrusion 322 and the positioning groove 323 are respectively disposed on the upper surface (upper end) and lower surface (lower end) of the tray 320, or the first positioning protrusion 322 and the positioning groove 323 are respectively disposed on the lower surface (lower end) and upper surface (upper end) of the tray 320. The two first positioning protrusions 322 are distributed horizontally or vertically, and the two positioning grooves 323 are relatively distributed horizontally or vertically. The overall shape of the first positioning protrusion 322 and the positioning groove 323 is rectangular or circular.

[0074] Reference Figure 10 In some embodiments, the receiving groove is provided with multiple sets of limiting members, each set of limiting members including multiple limiting members 313. The multiple limiting members 313 in the same set are used to form a limiting space for the limiting tray 320. The multiple limiting members 313 in the same set serve to limit a group of trays, preventing a group of trays from shifting or collapsing in the receiving groove. The receiving groove is provided with multiple sets of limiting members, so that multiple groups of trays can be limited in the receiving groove at the same time, increasing the number of trays 320 and developing rollers that the material box 310 can store, and facilitating the handling and turnover of more developing rollers.

[0075] The lower surface of the tray 320 is provided with four tubular support structures 325. The upper end of the push rod 410 is conical and is inserted into the center hole of the support structure 325, so that the push rod 410 can stably lift the tray 320.

[0076] Reference Figure 10 In some embodiments, a support plate 314 is provided in the storage slot. The support plate 314 is used to abut against the bottom of another material box 310. The support plate 314 makes the entire material box 310 more supportive, thereby enabling the material boxes 310 to be stacked in more layers and reducing the risk of the material box 310 being crushed.

[0077] In this embodiment, the material box 310 has a square shape and the cross-section of the storage slot is square. The material box 310 has a front side wall, a left side wall, a rear side wall, and a right side wall connected end to end. The material box 310 also has a bottom wall with four sides, which are respectively connected to the lower end faces of the front side wall, the left side wall, the rear side wall, and the right side wall. A support plate 314 is provided in the storage slot. The support plate 314 is plate-shaped and perpendicular to the left and right directions. The lower end of the support plate 314 is connected to the bottom wall, and the front and rear ends of the support plate 314 are respectively connected to the front inner wall and the rear inner wall of the storage slot. The support plate 314 divides the storage slot into a left half and a right half. The cross-section of the left half and the right half is square. A set of limiting members is provided in the left half and the right half. Each set of limiting members includes 8 limiting members 313. The material box 310 is symmetrical about one side perpendicular to the left and right directions, so that the material box 310 can hold two sets of trays. In the left half, two limiting members 313 are connected to the front inner wall of the storage slot, two limiting members 313 are connected to the left inner wall of the storage slot, two limiting members 313 are connected to the rear inner wall of the storage slot, and the remaining four limiting members 313 are connected to the left side of the support plate 314. The remaining four limiting members 313 can strengthen the structural strength of the support plate 314 and improve its support capacity. The eight limiting members 313 can also abut against the bottom of the other material box 310, thus supporting the other material box 310. The foolproof member 312 is connected to the limiting members 313 on the front inner wall of the storage slot. The foolproof member 312 and the limiting members 313 are coplanar, and the foolproof member 312 is deeper into the center of the storage slot than the limiting members 313.

[0078] The hopper 310 and pallet 320 are integrally molded. Both the hopper 310 and pallet 320 are typically made of plastic. The hopper 310 is manufactured using injection molding or compression molding processes.

[0079] In some embodiments, the material bin 310 includes a bottom wall and a peripheral wall surrounding the outer edge of the bottom wall. The bottom wall and the peripheral wall form a receiving groove. The bottom wall functions to support the tray 320 and the developing roller on the tray 320, while the peripheral wall functions to limit the tray 320 and the developing roller on the tray 320. The outer dimensions of the peripheral wall and the cross-sectional dimensions of the receiving groove gradually decrease from top to bottom, making it easy to demold the material bin 310 when it is manufactured using injection molding or compression molding processes. The peripheral wall is the aforementioned front side wall, left side wall, rear side wall, and right side wall.

[0080] Reference Figure 10 In some embodiments, the hopper 310 further includes a plurality of limiting parts 315, which are evenly connected to the upper end of the peripheral wall and extend into the receiving groove. The limiting parts 315 are used to press against the bottom wall of another hopper 310, and the peripheral wall of the hopper 310 supports the other hopper 310 through the limiting parts 315.

[0081] Reference Figure 13 The bottom wall has multiple downward-extending second positioning protrusions 316. These protrusions 316 can extend into the receiving groove and abut against the inner side of the limiting part 315, preventing the other material box 310 from shifting horizontally when stacked on top of it, thus achieving vertical alignment of the two material boxes 310. The bottom of the upper material box 310 can seal the receiving groove of the lower material box 310, preventing dust and other contaminants from entering the receiving groove through its opening, thereby preventing dust from adhering to the developing roller inside the receiving groove.

[0082] Reference Figure 10 or Figure 13 In some embodiments, the left and right ends of the material box 310 are provided with handles for hand gripping, making it convenient for workers to manually move the material box 310.

[0083] In some embodiments, the tray 320 is provided with two front-to-back support portions 326, both of which extend in the left-right direction. Each of the two support portions 326 is provided with a limiting notch 327. The two front-to-back opposing limiting notches 327 are used to receive the two ends of the developing roller. When the two ends of the developing roller are respectively inserted into the two front-to-back opposing limiting notches 327, the two support portions 326 can support and limit the developing roller.

[0084] A limiting notch 327 and a limiting groove 321 on one support part 326 and a limiting notch 327 on another support part 326 are aligned front to back, so that the limiting notch 327, the limiting groove 321 and the limiting notch 327 on another support part 326 can jointly limit a developing roller.

[0085] In some embodiments, the upper surface of the tray 320 is provided with a receiving groove, and a limiting groove 321 is provided at the bottom of the receiving groove. The limiting groove 321 extends in the front-back direction. Two support parts 326 are provided at the bottom of the receiving groove, and the two support parts 326 are arranged opposite to the front and rear ends of the limiting groove 321. The limiting notch 327 is directly opposite to the limiting groove 321. The receiving groove serves to accommodate the limiting groove 321, the two support parts 326, and the developing roller in the limiting groove 321, so as to prevent the support parts 326 and the developing roller from being higher than the upper surface of the tray 320, thereby preventing the upper tray 320 from crushing the support parts 326 of the lower tray 320 and the developing roller on the lower tray 320.

[0086] Reference Figure 11An avoidance area 328 is formed between the inner wall of the receiving groove and the support part 326. The avoidance area 328 is used for the end of the developing roller to extend into. The avoidance area 328 allows the clamping part 6221 to extend into and grasp the end of the developing roller. The clamping part 6221 clamps the end of the developing roller and extends into the avoidance area 328, thereby placing the developing roller in the limiting groove 321 and the two limiting notches 327. When the developing roller is placed in the limiting groove 321 and the two limiting notches 327, the clamping part 6221 extends into the avoidance area 328 and can clamp the developing roller.

[0087] The lower end of the pallet clamping arm 633 is provided with a second hook. The lower surfaces of both the front and rear ends of the pallet 320 are provided with first notches 329 (e.g., ...). Figure 11 or Figure 12 As shown, the first notch 329 is used for the second hook to extend into, and the second hook supports the area of ​​the pallet 320 corresponding to the first notch 329, so as to grasp the pallet 320, so that the pallet 320 can be gripped and moved by the pallet clamping arm 633. Of course, the first notch 329 can also be used by the worker's hand to grasp. The pallet 320 has a second notch at both the left and right ends, which is used for the worker's hand to grasp, so that the worker can move the pallet 320.

[0088] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
