Description

Technical Field

[0001] The present invention relates to the technical field of suspension conveying, and particularly relates to an intelligent suspension conveying system and method for fully automatic pulp molding products. Background Art

[0002] In the production process of pulp molding products (such as lunch boxes, trays, packaging liners, etc.), the suspension conveying of molds is a key link affecting production efficiency and product quality. Traditional conveying systems mostly rely on manual operation or fixed mechanical clamping devices, and there are the following core problems: low automation degree: frequent manual intervention is required for mold grasping, positioning, and angle adjustment, especially when connecting multiple processes, the efficiency is low, and product deformation or positioning deviation is likely to occur due to human error; single clamping method: conventional mechanical jaws can only fix the mold through rigid clamping, and it is difficult to adapt to special-shaped or thin-wall pulp products. Excessive clamping force may cause product indentation or even damage; frequent jamming faults: long-term contact between the mold insert and the connecting sleeve is easily affected by pulp residue, moisture, or oil stains, resulting in increased insertion and extraction resistance. The traditional system lacks self-processing ability and requires manual cleaning during shutdown. Therefore, we propose an intelligent suspension conveying system and method for fully automatic pulp molding products. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] As Figures 1 - 10As shown in the figure, an intelligent suspension conveying system and method for fully automatic pulp molding products, including a suspension rack 1. A fixed suspension conveying equipment main body 2 is arranged below the suspension rack 1. A moving electric mover 5 is arranged inside the suspension conveying equipment main body 2. The suspension conveying equipment main body 2 and the electric mover 5 are prior arts and will not be elaborated here. A number of installation cavities 3 are opened on the side of the suspension conveying equipment main body 2. An extrusion sensing structure 4 for monitoring the position of the electric mover 5 is arranged inside the installation cavity 3. A telescopic device 6 is fixedly installed on the bottom side of the electric mover 5. An installation shell 711 is fixedly installed on the bottom side of the telescopic device 6. A rotating rotating plate 712 is arranged below the installation shell 711. Two symmetrically distributed third connecting plates 811 are fixedly installed on the bottom side of the rotating plate 712. Two swing rotating teeth 812 that mesh and rotate with each other are arranged on the side of the two third connecting plates 811 corresponding to each other. Connecting columns 813 are fixedly installed at both ends of the two swing rotating teeth 812. Claw jaws 814 are fixedly installed on the sides of the two connecting columns 813 at both ends of one swing rotating tooth 812. A second connecting plate 815 is fixedly installed on the side of the two claw jaws 814 corresponding to each other. A fixed connecting sleeve 822 is arranged at the center position of the two third connecting plates 811 corresponding to the lower side of the swing rotating teeth 812. The connecting sleeve 822 is a block in the shape of a "hui" character. An inserting block 911 is arranged inside the connecting sleeve 822. A fixed support frame 912 is arranged on the bottom side of the inserting block 911. A guiding cavity 914 is opened on the side of the inserting block 911. Infrared distance sensors 834 are fixedly installed inside the two third connecting plates 811 corresponding to the upper side of the connecting sleeve 822. A second extrusion block 843 that is linked with the two rotating swing rotating teeth 812 is arranged inside the two third connecting plates 811 corresponding to the space between the infrared distance sensors 834 and the connecting sleeve 822. A second servo motor 816 is fixedly installed on the side of the third connecting plate 811. The output end of the second servo motor 816 is fixedly installed on the side of the connecting column 813. When in use, the electric mover 5 moves inside the suspension conveying equipment main body 2. When the electric mover 5 moves to the position of the extrusion sensing structure 4 at the feeding position, the movement of the electric mover 5 is monitored. When grasping is required, the telescopic device 6 is used to make the installation shell 711 move downward. The installation shell 711 drives the rotating plate 712 and the third connecting plates 811 to move downward. After the inserting block 911 moves into the connecting sleeve 822, the two swing rotating teeth 812 rotate in opposite directions, causing the two second connecting plates 815 to move towards each other. The inserting block 911 is clamped by the two second connecting plates 815. The telescopic device 6 is driven to drive the inserting block 911 to move upward. The electric mover 5 continues to move inside the suspension conveying equipment main body 2. When the movement of the electric mover 5 is monitored by the extrusion sensing structure 4 at the corresponding position at the discharging position, the electric mover 5 stops moving. The two swing rotating teeth 812 are rotated again.The two swinging rotating teeth 812 move the two second connecting plates 815 to the sides away from each other, the second connecting plates 815 cancel the clamping of the plug block 911, and the plug block 911 automatically falls off. When the plug block 911 is stuck in the connection sleeve 822 due to oil and dust, the position of the plug block 911 is monitored by the infrared distance sensor 834. When the plug block 911 is stuck in the connection sleeve 822, the two swinging rotating teeth 812 continue to rotate, and the swinging rotating teeth 812 cause the second extrusion block 843 to move downward. The second extrusion block 843 squeezes the upper end of the plug block 911 so that the plug block 911 falls off from the connection sleeve 822, and the pulp molded product is molded by the support frame 912. A rotating cavity 713 is provided inside the supporting and mounting shell 711, a rotating gear 714 is rotatably mounted inside the rotating cavity 713, a rotating plate 712 is fixedly mounted on the lower end of the rotating gear 714, an active rotating gear 715 meshing with the rotating gear 714 is rotatably mounted inside the rotating plate 712 at a position corresponding to the rotating gear 714, a first servo motor 716 is fixedly mounted on the upper end of the mounting shell 711, an output end of the first servo motor 716 is fixedly mounted on the end face of the active rotating gear 715, when the extrusion sensing structure 4 detects the position of the electric mover 5 and knows that the cargo needs to change its angle at this time, the first servo motor 716 drives the active rotating gear 715 to rotate, and the active rotating gear 715 drives the rotating The movable gear 714 rotates, and the rotating gear 714 drives the rotating plate 712 to rotate, and the angle of the cargo is changed by the rotating rotating plate 712. A rotating swing hook 851 is provided between the two clamping claws 814 corresponding to the swing rotating teeth 812, and a second fixed block 852 is fixedly installed on the side of the third connecting plate 811 corresponding to the position of the swing hook 851, and a second limiting block 853 is fixedly installed on the side of the second fixed block 852, and a third fixed block 854 is fixedly installed on the side of the second fixed block 852, and an adapter block 855 is fixedly installed on one side of the third fixed block 854. The two corresponding clamping claws 814 are driven to move by the swing rotating teeth 812, and the clamping claws 814 drive the swing hook 851 to move when moving. The swing hook 851 moves, and the upper side of the swing hook 851 contacts the second limit block 853, and the swing hook 851 is squeezed by the second limit block 853, so that the swing hook 851 rotates. After the swing hook 851 rotates out, it forms a hook shape. At this time, the plug block 911 can be hung on the swing hook 851 through the guide cavity 914. The sides of the two swing rotating teeth 812 are both provided with swing hooks 851, so as to change the clamping method. After hanging, the swing hook 851 continues to rotate, and the lower end of the swing hook 851 contacts the adapter block 855 to form a seal. During the movement of the wall, the plug block 911 is unhooked. The two clamping jaws 814 are provided with rotation holes 861 at the positions corresponding to the swing hooks 851.On the side of the swing hook 851 corresponding to the position of the rotating hole 861, rotating columns 864 are fixedly installed.

The swing hook 851 drives the rotating column 864 to rotate inside the rotating hole 861, and the torsion spring 863 drives the rotating column 864 to return to the initial position when not being squeezed;

[0041] The extrusion sensing structure 4 includes a sensing detector 411. The sensing detector 411 is snap - fitted inside the installation cavity 3.

When the electric mover 5 moves on the suspension conveying equipment main body 2, the side of the electric mover 5 squeezes the first connecting plate 414. The first connecting plate 414 squeezes the connecting block 413, and the connecting block 413 drives the sliding probe 412 to move. When the sliding probe 412 moves and the sensing detector 411 monitors the movement of the sliding probe 412, it means that the electric mover 5 has moved to the position corresponding to the sensing detector 411. At this time, the position of the electric mover 5 can be confirmed. At this time, the movement of the electric mover 5 can be controlled to stop the suspension conveying equipment main body 2 to process the material hung on the electric mover 5. When the angle of the material hung on the electric mover 5 needs to be changed, when the electric mover 5 moves to the position of the extrusion sensing structure 4, the rotating plate 712 is controlled to rotate to change the angle of the goods through the rotating plate 712;

Two third limiting blocks 913 are symmetrically and fixedly installed on the side surface of the inserting block 911. The third limiting block 913 is a rectangular block and an arc chamfer is provided on the side surface of the third limiting block 913. The two second connecting plates 815 move to the side of the inserting block 911 to squeeze the inserting block 911. At this time, the third limiting block 913 is arranged above the second connecting plate 815 to play a limiting role. On the inner sides of the two third connecting plates 811, a first fixing block 831 is fixedly installed. On one side of the two first fixing blocks 831 corresponding to each other, a second connecting rod 832 is fixedly installed.

At this time, the second squeezing block 843 can squeeze the inserting block 911 inside the connecting sleeve 822.

[0043] Usage method of an intelligent suspension conveying system for fully automatic pulp molding products;

[0044] S1: System initialization. The electric mover 5 moves to the loading station, the extrusion sensing structure 4 triggers a positioning signal, and the telescopic device 6 descends to insert the inserting block 911 into the mold support frame 912;

[0045] S2: Select the clamping mode (two-way clamping or hooking), and the second servo motor 816 drives the jaws 814 to close and lock the insert block 911;

[0046] S3: The electric mover 5 transports the mold to the processing position, and the first servo motor 716 adjusts the angle of the rotating plate 712 to complete the process;

[0047] S4: When discharging, the jaws 814 are released, and the infrared distance sensor 834 detects the state of the insert block 911. If it is jammed, the second extrusion block 843 is triggered to force demolding;

[0048] S5: The electric mover 5 returns to the loading position, and S1 - S4 are executed cyclically to achieve continuous fully automatic production.

[0049] The working principle of the present invention:

[0050] During use, after the system is started, the electric mover of the hanging conveyor equipment body moves along the preset track to the loading station. Through the inclined plane design of the triangular connecting block, the extrusion sensing structure converts the lateral displacement of the electric mover into the longitudinal displacement of the sliding probe. When the electric mover touches and presses the first connecting plate, the connecting block drives the sliding probe to compress the first spring, triggering the sensing detector to generate a in-place signal. Based on this, the control system locks the station coordinates and starts the telescopic device to descend vertically, aligning the plug block below the mounting shell with the connecting sleeve, and the clamping mode is selected and executed. Mode 1: Two-way clamping. The telescopic device drives the plug block to insert into the connecting sleeve, and the third limit block on the side of the plug block contacts the first limit block in the connecting sleeve to achieve preliminary positioning. The second servo motor is started to drive the connecting column to drive the swinging rotating teeth to mesh and rotate, causing the two second connecting plates to move towards the center and clamp the third limit blocks on both sides of the plug block. After clamping is completed, the telescopic device lifts the plug block, and the electric mover carries the mold to the processing station. Mode 2: Hook clamping. When the shape of the mold is complex or flexible grasping is required, the system switches to the hook clamping mode. When the clamping jaw moves, the swinging hook rotates in the rotating hole along with the rotating column. After its upper end contacts the second limit block on the side, it is squeezed and flipped outwards to form a hook-like structure. The plug block is hung into the swinging hook through the guiding cavity, and then the swinging hook continues to rotate until its lower end fits with the adapter block to form a sealed lock. The torsion spring provides a reset elastic force to ensure that the swinging hook remains closed when not subjected to external forces. After the mold is transported to the processing station, the extrusion sensing structure triggers a signal again, and the first servo motor is started to drive the driving rotating gear to mesh with the rotating gear, driving the rotating plate to rotate. By feedback of the angle data by the encoder, the system can accurately control the rotation of the mold to meet the requirements of different processes for the mold posture. After the electric mover moves to the unloading station, the clamping jaw releases the plug block. Under normal circumstances, the plug block automatically disengages from the connecting sleeve due to gravity, and the support frame supports the mold to complete the transfer. If the infrared distance sensor detects that the plug block still remains in the connecting sleeve, the system determines it as a jamming failure and immediately starts the second servo motor. The motor drives the connecting column to rotate, causing the first extrusion block to insert into the first groove of the sliding block, pushing the sliding block to move downward along the sliding groove, driving the second extrusion block at the bottom of the fourth connecting plate to squeeze the upper end of the plug block downward, forcing it to disengage from the connecting sleeve. The second spring rebounds after extrusion is completed to reset the sliding block. During the periodic operation of the system, the clearance design between the connecting sleeve and the plug block can reduce the adhesion of pulp residue. During maintenance, the infrared distance sensor in the detachable mounting sleeve can be removed to clean or replace damaged components. If the torsion spring of the swinging hook fails, the rotating column module can be directly replaced without overall disassembly of the clamping jaw.
