Description

Technical Field

[0001] This utility model relates to the field of automatic depalletizing and loading technology for bagged materials, and specifically to an automatic depalletizing and loading device. Background Technology

[0002] Depalletizing devices are widely used in logistics, warehousing, and manufacturing to automate the picking and handling of materials on pallets. Traditional depalletizing devices typically consist of a six-axis robotic arm and a lifting platform. During operation, a forklift first places the pallet loaded with materials onto the lifting platform. The platform positions the pallet and then lifts it to a suitable height so the six-axis robotic arm can pick up the materials and transfer them to the conveyor belt. After the materials are picked up, the lifting platform lowers, the forklift removes the empty pallets, and the empty pallets are stacked. After stacking, a new fully loaded pallet is placed on top, thus beginning the next round of operation. However, this traditional method of destacking has obvious drawbacks: Because the removal, stacking, and placement of new pallets all rely on manual operation throughout the process, the six-axis robot is idle for extended periods, resulting in discontinuous operation. This interruption not only reduces depalletizing efficiency but also increases labor costs and time consumption, making it difficult to meet the demands of modern industry for automation and high efficiency. Six-axis and four-axis robots, therefore, have relatively low depalletizing efficiency. Utility Model Content

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0016] To address the technical problems in the background section, the following automatic depalletizing and loading equipment is provided: Combination Figures 1-12 As shown, the present invention provides an automatic depalletizing and loading device, including a first depalletizer 100 and a second depalletizer 200. A first pallet stacker 300 is installed at the unloading end of the first depalletizer 100, a second depalletizer 200 is installed on one side of the first depalletizer 100, a second pallet stacker 400 is installed at the unloading end of the second depalletizer 200, and a first conveying device 500 and a second conveying device 600 are installed on the other side of the first depalletizer 100. The first depalletizer 100 includes a depalletizing frame 101, a feeding conveyor 102, and an empty pallet conveyor 103. A chain lifting conveyor 104 is installed in the middle of the depalletizing frame 101, and a chain lifting conveyor 104 is installed on one side of the depalletizing frame 101. A feeding conveyor 102 is installed at the feeding end of the chain lifting conveyor 104, and an empty tray conveyor 103 is installed on the other side of the destacking frame 101 at the unloading end of the chain lifting conveyor 104. The output end of the empty tray conveyor 103 extends to the middle of the first stacking machine 300. A baffle 105 is fixedly connected inside the destacking frame 101 at the unloading end of the chain lifting conveyor 104. A first unloading conveyor belt 106 and a second unloading conveyor belt 107 are fixedly connected to both sides inside the destacking frame 101, respectively. A destacking device is installed on the top surface of the destacking frame 101. The second destacking machine 200 adopts the same structure as the first destacking machine 100.

[0017] By combining two depalletizers (first and second depalletizers) with two conveyor systems (first and second conveyor systems), three working modes (simultaneous operation, handover and backup, and fault backup) are achieved to ensure continuous operation. The depalletizer has a built-in chain lifting conveyor and a feeding / empty pallet conveyor, which, together with the pallet stacker, realizes automatic conveying and storage of empty pallets, reducing manual intervention. The two depalletizers have the same structure, reducing maintenance costs, and the two conveyor systems divert materials, improving the overall depalletizing and loading efficiency.

[0018] In this embodiment, the destacking device includes a parallel frame 108. The top surface of the destacking frame 101 is fixedly connected to the parallel frame 108. The top surface of the parallel frame 108 is symmetrically fixedly connected to a parallel track 109. An adsorption component is slidably connected to the surface of the parallel track 109. One end of the top surface of the parallel frame 108 is fixedly connected to a parallel motor 110. The output end of the parallel motor 110 is connected to a transmission rod 111 through a reducer. A main belt gear 112 is fixedly connected to the surface of the transmission rod 111. A driven belt gear 113 is installed at the other end of the top surface of the parallel frame 108. The surface of the main belt gear 112 is rotatably connected to the driven belt gear 113 through belt teeth 114.

[0019] The parallel tracks on the parallel frame limit the movement trajectory of the adsorption components. The parallel motor drives the adsorption components to move smoothly along the tracks via a reducer, master-slave belt gears and belt teeth. The transmission structure has strong synchronization, ensuring that the adsorption components are accurately aligned with the stacked materials, avoiding gripping failures caused by deviation, laying a stable foundation for subsequent lateral movement and lifting gripping actions, and improving the accuracy and efficiency of destacking and gripping.

[0020] In this embodiment, the adsorption assembly includes a transverse track 115, with both ends of the transverse track 115 fixedly connected to the surface of the belt teeth 114. A transverse track 115 and a transverse rack 117 are fixedly connected to one side of the transverse track 115, and a transverse plate 118 is slidably connected to the surface of the transverse track 115. A transverse motor 119 is fixedly connected to one side of the transverse plate 118, and a transverse gear 120 is fixedly connected to the output end of the transverse motor 119. The transverse gear 120 meshes with the transverse rack 117.

[0021] The transverse motor drives the transverse gear to move along the transverse rack, which in turn drives the transverse plate to slide laterally along the transverse track, thereby adjusting the lateral position of the vacuum suction cup. This structure enables fine-tuning of the adsorption components, which can adapt to materials with different stacking spacing and width, expand the gripping coverage area, eliminate the need for manual adjustment of material stacking, and improve the equipment's adaptability to materials of different specifications.

[0022] In this embodiment, the adsorption assembly further includes a lifting motor 121 and a lifting arm 122. The lifting arm 122 is slidably connected to one side of the transverse plate 118, and a lifting rack 123 is fixedly connected to one side of the lifting arm 122. The lifting motor 121 is fixedly connected to the other side of the transverse plate 118. A lifting gear 124 is fixedly connected to the output end of the lifting motor 121. The lifting gear 124 meshes with the lifting rack 123. An adsorption component is installed on the bottom surface of the lifting arm 122.

[0023] The lifting motor drives the lifting arm to slide along the transverse plate through the meshing of the lifting gear and the lifting rack, achieving smooth lifting. The gear and rack transmission has self-locking properties, which can stably fix the position of the lifting arm after lifting, preventing materials from falling. The lifting action is precise and controllable, and the lifting stroke can be adjusted according to the material stacking height to ensure that the vacuum suction cup makes stable contact with the material, improve the gripping stability, and reduce material loss.

[0024] In this embodiment, the adsorption component includes a connecting plate 125. The bottom surface of the lifting arm 122 is fixedly connected to the connecting plate 125, and the bottom surface of the connecting plate 125 is rotatably connected to a rotating plate 126. The bottom surface of the rotating plate 126 is fixedly connected to a damping rod 127, and the bottom surface of the damping rod 127 is fixedly connected to a vacuum suction cup 128. The top surface of the connecting plate 125 is fixedly connected to a horizontal rotating motor 129, and the output end of the horizontal rotating motor 129 is rotatably connected to the rotating plate 126 through a gear set.

[0025] The rotary motor drives the rotating disk to rotate via a gear set, thereby adjusting the direction of the material adsorbed by the vacuum suction cup, ensuring that the bag openings of the material are consistent each time it is conveyed, and improving the regularity of subsequent conveying and loading; the damping rod can buffer the contact impact force between the vacuum suction cup and the material during adsorption, avoiding material damage; the uniform orientation of the material can reduce jamming during the conveying process, further improving the overall operation efficiency.

[0026] In this embodiment, the first conveying device 500 includes a fixed platform 501, a first inclined conveyor belt 502 is installed on the top surface of the fixed platform 501, the output end of the first unloading conveyor belt 106 is also installed with the first inclined conveyor belt 502, the unloading end of the first inclined conveyor belt 502 is installed with a first square roller conveyor 503, the unloading end of the first square roller conveyor 503 is installed with a first linear conveyor 504, the unloading end of the first linear conveyor 504 is installed with a first curved belt conveyor 505, the unloading end of the first curved belt conveyor 505 is installed with a second linear conveyor 506, and the unloading end of the second linear conveyor 506 is installed with a first inclined unloading roller 507.

[0027] The first inclined conveyor belt solves the height difference problem, the first square roller conveyor and the straight conveyor ensure smooth horizontal conveying, the first turning belt conveyor realizes directional adjustment, and the first inclined discharge roller realizes smooth material discharge; the multi-section conveying equipment is connected and coordinated to form a complete first conveying channel, ensuring that the material is continuously and smoothly conveyed to the next process after being discharged from the first depalletizer, thus improving the stability and efficiency of conveying.

[0028] In this embodiment, the second conveying device 600 includes a second inclined conveyor belt 601, the second unloading conveyor belt 107 is equipped with the second inclined conveyor belt 601 at its unloading end, the second square roller conveyor 602 is equipped with the unloading end of the second inclined conveyor belt 601, the second curved belt conveyor 603 is equipped with the unloading end of the second square roller conveyor 602, and the second inclined unloading roller 604 is equipped with the unloading end of the second curved belt conveyor 603.

[0029] The second inclined conveyor belt, the second square roller conveyor, the second turning belt conveyor, and the second inclined unloading roller form a simple and efficient second conveying channel, accurately receiving materials from the second depalletizer. Together with the first conveying device, they form a dual-path parallel structure, and with the three working modes of the dual depalletizer, they can realize material diversion or alternating conveying, further improving the overall efficiency and continuity of depalletizing and loading, while the simplified structure facilitates maintenance.

[0030] Working principle and usage process of this utility model: In use: During destacking, the following three situations may occur: In the first scenario, when the first depalletizer and the second depalletizer are working simultaneously, the first depalletizer feeds the first conveyor device with packages, while the second depalletizer feeds the second conveyor device with packages. The second method is that when the first depalletizer is stopped and loading material, the second depalletizer will sequentially feed the first conveyor and the second conveyor. Conversely, when the first depalletizer is stopped and loading material, the first depalletizer will sequentially feed the first conveyor and the second conveyor. The third method involves the depalletizer malfunctioning, in which the other depalletizer sequentially feeds packages to the first and second conveying devices.

[0031] During destacking: First, workers use forklifts to transport pallets and the bagged materials stacked on them to the feeding conveyor 102. The feeding conveyor 102 then begins operation, conveying the stacked materials and pallets to the chain lifting conveyor 104. The motor of the lifting conveyor 104 drives the sprocket, which in turn moves the chain upwards, thus lifting the conveyor. Therefore, the pallets are positioned above the conveyor when they reach the chain lifting conveyor 104. Next, workers use forklifts again to place the second set of stacked pallets onto the feeding conveyor 102. The second set of stacked pallets remains on the feeding conveyor 102, waiting for all materials to be removed from the chain lifting conveyor 104 and for the empty pallets to be conveyed out by the conveyor on the chain lifting conveyor 104 before the second set of materials can enter the chain lifting conveyor 104. After the empty pallets are conveyed out, they are transported by the empty pallet conveyor 103 to the middle of the stacking machine, where they are stacked and stored. The second step is that when the first set of stacked materials is transported to the middle by the chain elevator 104, the conveyor in the chain elevator 104 stops working and begins to lift the pallet material. When the pallet material rises to a certain height, it begins to grab the material bag. During the bag-grabbing process, firstly, the parallel motor 110 is started. When the parallel motor 110 is working, it drives the transmission rod 111 to rotate via the reducer. When the transmission rod 111 is working, it drives the main belt gear 112 to rotate. When the main belt gear 112 rotates, it drives the belt gear 114 to rotate under the action of the driven belt gear 113. When the belt gear 114 rotates, it moves the adsorption assembly. When the adsorption assembly moves above the stacked material, the parallel motor 110 is stopped, and simultaneously, the [unclear - possibly a device or mechanism] is started. When the transverse motor 119 is working, it drives the transverse gear 120 to rotate. When the transverse gear 120 rotates, it moves on the transverse rack 117, thereby driving the transverse plate 118 to travel on the transverse track 115. When the transverse plate 118 moves, it drives the vacuum suction cup 128 to move. When the vacuum suction cup 128 moves above the material to be suctioned, the transverse motor 121 stops working, and simultaneously, the lifting motor 121 starts working. During operation, the lifting gear 124 will rotate, thereby causing the lifting rack 123 to move. When the lifting rack 123 moves downward, it will cause the lifting arm 122 to move downward. When the lifting arm 122 moves downward, it will cause the vacuum suction cup 128 to move downward, so that the bottom surface of the vacuum suction cup 128 contacts one side of the material and adsorbs it. After adsorption, the lifting motor 121 will drive the lifting arm 122 to move upward and extract the adsorbed material. After extraction, the lifting motor 121 will lock itself. The parallel motor 110 drives the vacuum suction cup 128 and the adsorbed material to move onto the first feeding conveyor belt 106 or the second feeding conveyor belt 107. When the material is moved above the first feeding conveyor belt 106 or the second feeding conveyor belt 107, the parallel motor 129 starts to work, which drives the rotating disk 126 and the vacuum suction cup 128 to rotate, thereby driving the adsorbed material to rotate. When the adsorbed material rotates, it can be ensured that the direction of the material conveyed each time is consistent, that is, the direction of the bag opening is consistent. Once the bag openings are aligned, the vacuum suction cup 128 will no longer adsorb the material. At this point, the material will fall onto the first feeding conveyor belt 106 or the second feeding conveyor belt 107 under the influence of gravity. Then, the first feeding conveyor belt 106 can transport the material to the first conveying device 500, while the second feeding conveyor belt 107 can transport it to the second conveying device 600. The first conveying device 500 will transport the material to the next process via the first inclined conveyor belt 502, the first square roller conveyor 503, the first straight conveyor 504, the first curved belt conveyor 505, the second straight conveyor 506, and the first inclined unloading roller 507. The second conveying device 600 can transport the material to the next process through the cooperation of the second inclined conveyor belt 601, the second square roller conveyor 602, the second curved belt conveyor 603, and the second inclined unloading roller 604. After the first set of materials is completely removed, the chain lifting conveyor 104 drives the pallet back to its original position and transports it to the empty pallet conveyor 103. Then, the pallet is stored by the stacking machine.
