Description

Technical Field

[0001] This utility model relates to the field of cardboard box recycling technology, specifically to a cardboard box recycling device. Background Technology

[0002] Currently, in a cardboard box recycling system, when a production task is being carried out, an electric forklift is manually operated to remove an empty pallet from the empty pallet storage point and transport it to a designated location. The empty pallet is then manually moved onto a cardboard box rack, causing the pallet to move upwards. The pallet receives cardboard boxes, and after receiving a certain number of cardboard boxes, it becomes a full pallet, which is then moved downwards. The full pallet is then manually removed, and the electric forklift is manually operated to transport the full pallet to the storage point. However, the current cardboard box recycling system has the following problems when recycling cardboard boxes: 1. Due to the varying strength of the cardboard boxes, deformation occurs during transportation, causing displacement of the falling position during the cardboard box stacking process. Secondly, since the cardboard boxes fall horizontally, there is a certain height difference when they fall to the stacking position, and there is also a certain amount of slippage due to air fluid resistance during the fall, resulting in inconsistent landing points for each cardboard box. Therefore, the full carton pallets after stacking are irregularly shaped, which is not conducive to the automatic transport of AGV carts, and also to the planning of the full pallet storage area in the warehouse and the improvement of space utilization; 2. Empty pallets are manually removed from the electric forklift and replenished to the carton rack, and full carton pallets are manually removed from the carton rack and transported to the electric forklift by operating the electric forklift, which is labor-intensive; 3. There is no pallet storage area in the carton recycling system, so one pallet needs to be replenished at the end of each production batch. The task of removing full carton pallets needs to be completed first and then the task of replenishing empty pallets needs to be completed. Therefore, two additional actions are added: temporary placement of empty pallets and full carton pallets, which is inefficient. Utility Model Content

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0032] Please see Figures 1 to 13 . A cardboard box recycling device according to an embodiment of the present invention includes a transport component, a lifting component 2, a carrying component 3, a straightening component 4, a pallet 1, and a support component 5 for supporting the lifting component 2 and the straightening component 4 respectively. The lifting component 2 is connected to the carrying component 3. The support component 5 has a first storage area matching the carrying component 3 for storing the pallet 1. The transport component is used to take out the pallet 1 from the second storage area where empty pallets are stored and transport the pallet 1 to the first storage area. The carrying component 3 is used to be lowered by the lifting component 2 to a height matching a pallet 1 and connected to the pallet 1. The lifting component 2 is used to raise the carrying component 3 to a first preset height, so that the pallet 1 connected to the carrying component 3 moves to a first preset position and receives cardboard boxes. The straightening component 4 is used to straighten the cardboard boxes received on the pallet 1 to a first preset state. The lifting component 2 is used to lower the carrying component 3 to a second preset height, so that the pallet 1 receiving at least one cardboard box moves to the second preset position. The transport component is used to transport the pallet 1 separated from the carrying component 3 to a third storage area. The first preset height is higher than the second preset height.

[0033] Here, the first preset state refers to the state when the cardboard box is placed squarely on the pallet 1, without any tilting. Each side of the cardboard box corresponds to a side of the pallet 1. If the cardboard box is tilted or one side protrudes beyond the area where it is positioned in the first preset state on the pallet 1, the straightening component 4 straightens the cardboard box. After the pallet 1 receives a cardboard box, if the box is not in the first preset state, the straightening component 4 straightens the box to ensure its shape is regular. In the prior art, the support component 5 does not have a first storage area for storing the pallet 1. In existing cardboard box recycling equipment, a drive shaft is installed in the middle near the ground, preventing the transport component from entering the support component 5. The transport component can only place the pallet 1 outside the support component 5, and the pallet 1 is manually moved to the carrier component 3. After the pallet 1 completes its carton receiving task, it is manually moved to the transporter. The second storage area of ​​this application is for empty pallets. The transporter takes the pallet 1 out of the second storage area and places it inside the support member 5. Then, the pallet 1 is placed in the first storage area. The lifting member 2 drives the carrier member 3 to descend to a height matching that of a pallet 1, so that the carrier member 3 can be connected to the pallet 1. After the pallet 1 completes its carton receiving task, the lifting member 2 drives the carrier member 3 to descend to a second preset height, so that the pallet 1, which has received at least one carton, moves to the second preset position. The transporter is connected to the pallet 1, and the carrier member 3 is separated from the pallet 1. The transporter then transports the pallet 1, which is separated from the carrier member 3, to the third storage area. Compared with the prior art, this application can achieve full automation, save manpower, and improve work efficiency. This application is mainly used for the supporting equipment of the silk production line, covering functions such as automatic pallet feeding, carton stacking, carton straightening and automatic transport of transport items. The main technical problem to be solved is to realize the functions of automatic pallet feeding, carton straightening and interaction with transport items through design, and finally realize the automatic recycling of carton.

[0034] Specifically, the lifting component 2 is used to drive the carrier component 3 to rise to the first preset height, so that the pallet 1 connected to the carrier component 3 moves to the first preset position. After the carton is conveyed by the preceding conveying equipment, it falls freely onto the pallet 1, thereby realizing the receiving of the carton by the pallet 1.

[0035] Specifically, the process for recycling cartons in the existing carton recycling system includes: the unpacking system receives information indicating the end of the batch production task; the operator notifies the electric forklift driver; the forklift moves to a fixed position and picks up one empty pallet; the empty pallet is temporarily placed outside the safety door of the carton recycling system; the safety door of the carton recycling system is opened; the full carton pallet 1 is removed and temporarily placed outside the safety door of the carton recycling system; the empty pallet outside the safety door of the carton recycling system is placed into the carton recycling system; the safety door of the carton recycling system is closed; the full carton pallet 1 is transported to the storage point, and the unpacking system begins production; the batch production ends. The automatic unpacking system for the leaf processing pretreatment completes the tasks of removing the inner and outer cartons from the raw tobacco packs, removing the inner lining paper, and removing the plastic bags. The inner and outer cartons removed from the raw tobacco packs are stacked on pallet 1 by the palletizer in the automatic unpacking system. Currently, the empty pallets used in the automatic unpacking system's carton palletizer are replenished manually, and the recycled cartons are accumulated until the end of the batch production and then manually transported to the storage point. Manual transport involves the automated unpacking system's operator notifying relevant personnel to transport the materials to a designated location using a manual (electric) hydraulic forklift. The route is: manual (electric) hydraulic forklift parking point → empty pallet storage point → production line transport point retrieval → storage point. However, due to the long distance between the manual (electric) hydraulic forklift parking points and the production line transport points (which require traversing non-production areas), delays in personnel response (due to poor communication within the workshop and long routes), haphazard and non-standard transport routes, and errors at transport points are common. Furthermore, the entire carton recycling process reveals low efficiency for electric forklift drivers. Each production batch requires replenishing one pallet (1), and the forklift must first remove the full carton pallet (1) before replenishing the empty one. This adds two actions: temporary placement of empty and full carton pallets (1) and opening and closing the door. The entire process from the end of one production batch to the start of the next requires seven steps to complete the carton recycling task. The process for cardboard box recycling in this application includes: the unpacking system receives the end-of-batch production information; it interacts with the transport component to determine if there are empty pallets inside the support component 5; if no empty pallets are found inside the support component 5, the transport component moves to a fixed location to retrieve a group of empty pallets (5 pallets per group), the transport component moves outside the support component 5, the electric door 55 opens, the transport component places the empty pallet group inside the support component 5, the transport component removes the full cardboard box pallet 1, the electric door 55 closes, the full cardboard box pallet 1 is transported to the storage point, the unpacking system starts production, and the current batch production ends; if an empty pallet is found inside the support component 5, the transport component moves outside the support component 5, the electric door 55 opens, the transport component removes the full cardboard box pallet 1, the electric door 55 closes, the full cardboard box pallet 1 is transported to the storage point, the unpacking system starts production, and the current batch production ends. This application optimizes the workflow, reduces multiple repetitive steps, and greatly improves the efficiency of cardboard box recycling.

[0036] As a type of cardboard box recycling device in this embodiment, it may also include a plurality of positioning frames 6 disposed in the first storage area for positioning the left side, right side and rear side of the pallet 1 respectively.

[0037] Specifically, the first storage area can be a rectangular storage area, and the tray 1 can be a rectangular structure. The bottom end of the positioning frame 6 is fixed to the ground. The positioning frame 6 can be an L-shaped structure, and there can be two positioning frames 6. The two positioning frames 6 are respectively located at the two rear corners of the first storage area. Thus, one positioning frame 6 can position the left and rear ends of the tray 1 respectively, and the other positioning frame 6 can position the right and rear ends of the tray 1 respectively. The inlet of the support member 5 is located close to the user. The inlet of the support member 5 is the front side, and the position on the support member 5 away from the inlet is the rear side. Therefore, the part of the tray 1 close to the inlet of the support member 5 is the front end of the tray 1, and the part of the tray 1 away from the inlet of the support member 5 is the rear end of the tray 1. The part on the left side of the tray 1 is the left end of the tray 1, and the part on the right side of the tray 1 is the right end of the tray 1.

[0038] There can be multiple pallets 1. The transporter is used to take out multiple pallets 1 arranged vertically in the second storage area and transport the multiple pallets 1 to the first storage area. The height of the highest pallet 1 in the first storage area is not higher than the second preset height.

[0039] Specifically, the pallet 1 may include a receiving plate for receiving cartons, multiple support legs disposed at the bottom of the receiving plate, and fork holes provided between the support legs, between the receiving plate and the support legs, or on the receiving plate.

[0040] The support member 5 may include two support columns 53 arranged symmetrically on the left and right. The lifting member 2 includes two first lifting structures arranged symmetrically on the left and right and a first drive structure for driving the two first lifting structures respectively. The two first lifting structures are respectively connected to the two support columns 53. The carrying member 3 includes two first telescopic fork structures 31 arranged symmetrically, and two first connecting structures 32 respectively connected to the two first lifting structures and the two first telescopic fork structures 31. The first lifting structure is used to drive the first connecting structure 32 connected to it to move up and down. One first telescopic fork structure 31 is used to extend a first preset length and insert into the fork hole of the pallet 1 to connect with the pallet 1 when it is at a height matching a pallet 1. The two telescopic fork structures are used to carry the pallet 1. The first telescopic fork structure 31 is used to shorten the first preset length to separate from the pallet 1 when the transport member is connected to the receiving carton pallet 1.

[0041] The support column 53 can be hollow inside. The first lifting structure is set inside the support column 53 and connected to the support column 53. The two support columns 53 have two adjacent sides with first connecting holes. The support member 5 also includes two slide rails 57 connected to the two adjacent sides of the two support columns 53 respectively. The first connecting structure 32 includes a first slider 322 and a first connecting plate 321. One end of the first slider 322 is connected to the first telescopic fork structure 31, and the other end is slidably connected to the slide rail 57. One end of the first connecting plate 321 is connected to the first telescopic fork structure 31, and the other end passes through the first connecting hole and is connected to the first lifting structure.

[0042] Specifically, to reduce the working height for picking up empty pallets below, this application reverses the installation of the first telescopic fork structure 31, placing the fork portion of the first telescopic fork structure 31 below and the transmission portion above, thereby reducing the height of the fork portion. The first telescopic fork structure 31 is connected to the first lifting structure via the first connecting structure 32. The slide rail 57 can be a dovetail linear guide pair, which serves as the guide and support for vertical lifting. Driven by the first drive motor 21, the first drive shaft 22, the first sprocket 23, the second sprocket 25, the first rotating shaft 26, the third sprocket 27, the fourth sprocket 28, the second rotating shaft 210, the first chain 24, and the second chain 29, the left and right first telescopic fork structures 31 can achieve synchronous lifting. By using the first telescopic fork structure 31, it is possible to pick up a single empty pallet or retract it to a standby state when there is an empty pallet below the first telescopic fork structure 31. The retracted length of the first telescopic fork structure 31 is half of its extended length, which maximizes space utilization and makes the structure of this application more compact.

[0043] Specifically, the first telescopic fork structure 31 can adopt the three-layer telescopic fork disclosed in Chinese Patent CN215756228U, "A Three-Layer Telescopic Fork with Short-Distance Telescopic Extension". The first telescopic fork structure 31 can also adopt the automatic telescopic fork disclosed in Chinese Patent CN218145698U, "An Automatic Telescopic Fork for a Narrow Space Pallet with a Grid Bottom". The first telescopic fork structure 31 can also adopt the telescopic fork device disclosed in Chinese Patent CN219279415U, "A Rotatable Telescopic Fork Device". The first telescopic fork structure 31 can also adopt the telescopic fork disclosed in Chinese Patent CN220618333U, "An Installable and Detachable Telescopic Fork".

[0044] The first drive structure may include a first drive shaft 22 and a first drive motor 21 for driving the first drive shaft 22. The first lifting structure includes a first sprocket 23, a second sprocket 25, a first rotating shaft 26, a third sprocket 27, a fourth sprocket 28, a second rotating shaft 210, a first chain 24, and a second chain 29. The first sprocket 23 of the first lifting structure is connected to the left or right end of the first drive shaft 22. The two ends of the first chain 24 are respectively engaged with the first sprocket 23 and the second sprocket 25. The two ends of the second chain 29 are respectively engaged with the third sprocket 27 and the fourth sprocket 28. The first rotating shaft 26 is respectively sleeved on the second sprocket 25 and the third sprocket 27. The second rotating shaft 210 is sleeved on the fourth sprocket 28. The first drive shaft 22, the first rotating shaft 26, and the second rotating shaft 210 are respectively rotatably connected to the support column 53.

[0045] Specifically, the first sprocket 23, the second sprocket 25, the first chain 24, and the first shaft 26 form a primary chain drive mechanism, and the third sprocket 27, the fourth sprocket 28, the second shaft 210, and the second chain 29 form a secondary chain drive mechanism. The axis of the second chain 29 is perpendicular to the axis of the first chain 24, and the axis of the second chain 29 is parallel to the vertical direction, while the axis of the first chain 24 is parallel to the horizontal direction.

[0046] Specifically, the first drive motor 21 is installed in the middle of the rear side and is connected to the first-stage chain drive mechanism and the second-stage chain drive mechanism through the first drive shaft 22. The support column 53 has an L-shaped structure and is a square tube with a hollow interior. The first part of the support column 53 is vertically arranged and the second part is horizontally arranged. The first sprocket 23, the first drive shaft 22, and the first chain 24 are arranged in the second part of the support column 53. The second sprocket 25, the first rotating shaft 26, and the third sprocket 27 are arranged at the connection between the first part and the second part of the support column 53. The second chain 29, the fourth sprocket 28, and the second rotating shaft 210 are arranged in the first part of the support column 53. The first drive shaft 22 is horizontally arranged and is rotatably connected to the support column 53. The first connecting through hole is arranged through the first part of the support column 53. A first mounting base is welded to the bottom of the support column 53 and connected to the ground by expansion bolts to ensure the entire equipment has solid support. The vertical part of the support column 53 is provided with a first connecting through hole, and the slide rail 57 is fixed to the outer surface of the support column 53 with screws. The support member 5 also includes a first protective shell connected to one side of one support column 53 and the first drive motor 21, and a second protective shell connected to the other side of the other support column 53 and the first drive motor 21. Since the first drive motor 21 and the first transmission shaft 22 are respectively located on the rear side, a first storage area can be set inside the support member 5 below the carrier 3, thereby facilitating the free entry of transport items into the support member 5 and the transport of the pallet 1 to the first storage area.

[0047] The support member 5 may include a first transverse support rod 51 located at a second preset length on the front side of the support column 53, and a second transverse support rod 52 located at a third preset length on the rear side of the support column 53. The straightening member 4 includes a front limiting structure 41 connected to the first transverse support rod 51, a rear adjusting structure 42 connected to the middle of the second transverse support rod 52, two left adjusting structures 43 respectively connected to the first part of the first transverse support rod 51 and the first part of the second transverse support rod 52, and two right adjusting structures 44 respectively connected to the second part of the first transverse support rod 51 and the second part of the second transverse support rod 52.

[0048] Specifically, the left adjustment structure 43, right adjustment structure 44, and rear adjustment structure 42 all include a first push plate for pushing the carton and a first cylinder for pushing the first push plate. The left adjustment structure 43 and right adjustment structure 44 are both driven by cylinders and are designed with linear guide rails for support and guidance. The rear adjustment structure 42 is driven by a guide rail type cylinder. The first cylinder of the rear adjustment structure 42 is bolted to the second transverse support rod 52. The first cylinders of the left and right adjustment structures 44 are bolted to the first transverse support rod 51 and the second transverse support rod 52, respectively. To ensure that the cartons conveyed by the preceding conveyor have a relatively regular overall shape when stacked, a front limit structure 41 is used at the front end of the carton's falling position in the conveying direction to prevent the carton from rushing out too far. The front limit structure 41 can be a baffle. After the carton falls to the pallet position, a telescopic cylinder is used to push the rearmost carton forward to the accurate position. At the same time, two sets (four in total) of cylinder push plates are designed on each of the left and right sides to ensure that the carton can be accurately positioned on the left and right sides after falling to the pallet position.

[0049] Specifically, the left adjustment structure 43 and the right adjustment structure 44 can respectively adopt the adjustable push plate disclosed in Chinese Patent CN222662765U, a waste cardboard box recycling and compression device, a first linkage plate connected to one end of the adjustable push plate via a rotating shaft, and a follower push plate connected to the end of the first linkage plate away from the adjustable push plate via a rotating shaft. The rear adjustment structure 42 can adopt the follower push plate on the left and the follower push plate on the right, both disclosed in Chinese Patent CN222662765U, with a second linkage plate connected to the other end of the follower push plate on the left and the other end of the follower push plate on the right. The adjustable push plate moves towards the cardboard box position inside the support member 5. At the same time, under the traction of the first linkage plate and the second linkage plate, the angle between the follower push plate and the first linkage plate and the second linkage plate decreases, causing the follower push plate to be pulled and moved, pushing the stacked cardboard boxes. The adjustable pusher and the follower pusher can quickly and neatly stack cartons to a certain height, ensuring flat stacking and preventing displacement caused by continuous stacking. The backs of the adjustable pushers on the same side are connected by linkage arms. Second cylinders are installed on both sides of the support 5, with push rods at the output ends of the second cylinders penetrating the channel and connecting to the surface of the linkage arms. During operation, the second cylinders drive the adjustable pushers to move, thereby pulling the follower pushers. A pair of guide posts that move synchronously with the linkage arms are arranged on their surfaces. The support 5 also has limiting baffles to accommodate the guide posts. As the linkage arms move with the adjustable pushers, the guide posts slide along a lateral trajectory on the surface of the limiting baffles, ensuring the straightness of the movement of the linkage arms and adjustable pushers.

[0050] The support member 5 may also include a first support frame 54 disposed on the front side, an inlet disposed through the first support frame 54, an electric door 55 for sealing the inlet, and a second drive structure for driving the electric door 55.

[0051] Specifically, the support component 5 also includes a first connecting rod, a second connecting rod, a fence 56, and a safety light curtain. The two ends of the first connecting rod are connected to the front sides of the first support frame 54 and the support column, respectively. The middle of the first connecting rod is connected to the first transverse support rod 51. The two ends of the second connecting rod are connected to the rear sides of the support column 53 and the second transverse support rod 52, respectively. There can be two symmetrically arranged first connecting rods and two symmetrically arranged second connecting rods. Multiple fences 56 are present. The first fence 56 is connected to one end of the first support frame 54 and the front side of one support column 53. The second fence 56 is connected to the rear side of one support column 53. The third fence 56 is connected to the other end of the first support frame 54 and the front side of another support column 53. The fourth fence 56 is connected to the rear side of another support column 53. The electric door 55 is located at the front end in the carton output direction and adopts a structure of two fixed doors and two left and right sliding doors. The electric door 55 is driven and installed on the transverse support beam of the upper equipment. During production, the electric door 55 is in the closed state to prevent personal injury and damage to the equipment body caused by personnel or other objects entering during equipment operation. The automatic door opening and closing function is mainly used by the automatic cardboard box recycling device to replenish empty pallet groups and to automatically open and close the door through information interaction when the cardboard box pallet 1 is full at the end of a production batch. Safety light curtains (multiple sets of through-beam photoelectric sensors) are installed on both sides of the door frame of the electric door 55 to provide an anti-pinch function when closing. A fence 56 is installed around the equipment, with a height of not less than 2 meters. It is used to separate the equipment's working area from other non-working areas to prevent safety accidents during automatic operation.

[0052] Specifically, this application features a compact structure and strong load capacity, integrating automatic pallet feeding 1 and automatic carton collection into a single unit design, allowing for efficient placement in confined workshop spaces. The telescopic fork structure can be a three-stage telescopic fork, enabling ultra-low, close-to-the-ground pallet picking up, achieving uninterrupted automatic pallet feeding. This application is equipped with multiple safety protections to prevent personnel from entering during automatic operation, and the electric door 55 has an anti-pinch function.

[0053] The transport component may include an AGV trolley, a second fork structure, and a second lifting structure connected to the AGV trolley and the second fork structure respectively. The second fork structure can be inserted into the fork hole of the pallet 1 to connect with the pallet 1, and the second lifting structure is used to drive the second fork structure to move up and down.

[0054] Specifically, the second fork structure can be a fixed fork structure. Initially, the first lifting structure does not raise the second fork structure. The AGV moves to the second storage area, and the second fork structure is connected to the pallet. The AGV moves to the first storage area, and the second fork structure can place the pallet 1 from the second storage area into the first storage area. The lifting component 2 lowers the carrier component 3 to a second preset height, causing the pallet 1, which receives at least one carton, to move to a second preset position. At this time, the second lifting structure raises the second fork structure to a height matching the second preset position. The second fork structure picks up the fork holes of the pallet 1, and then the second fork structure is connected to the pallet 1. The carrier component 3 separates from the pallet 1, and the AGV transports the pallet 1 to the third storage area, thereby transporting the carton to the third storage area.

[0055] Specifically, the AGV retrieves empty pallet sets (5 layers per set) at the storage point. Then, based on the order tasks and map path planning of the scheduling system, it sends the retrieved empty pallet sets into the retrieval port. After interacting with the cardboard box recycling device, the electric door 55 opens, and the AGV places the empty pallet sets on the ground at the designated location on the equipment before returning.

[0056] As one embodiment of the cardboard box recycling device, it may also include a detection structure for detecting the movement height of the carrier 3, and a controller for controlling the lifting member 2, the carrier 3 and the straightening member 4 respectively.

[0057] Specifically, it may also include 5 sets of diffuse reflection photoelectric switches located in the area behind the first storage area. Each empty pallet group contains a maximum of 5 empty pallets, with each of the 5 pallets 1 in the height direction corresponding to a specific position in the empty pallet group, used to detect the actual number of empty pallets. Simultaneously, the number of pallets 1 is fed back to the electronic control system, facilitating the first telescopic fork structure 31 to accurately pick up the top layer of empty pallets. After being folded and flattened by the preceding equipment, cartons are conveyed by a conveyor chain to the top of the carton recycling device and fall vertically, one carton at a time. The vertically falling cartons land on the empty pallets on the first telescopic fork structure 31. After each carton falls, the adjusting structure 42 extends, pushing the carton forward to a limit position, correcting its front-to-back position. Subsequently, the left and right adjusting structures 44 extend to correct the left-to-right position of the carton. The detection structure can be multiple photoelectric switches. The height of the stacked cartons is detected by the photoelectric switches. When the height exceeds the limit, the first telescopic fork structure 31 causes the pallet 1 and cartons to descend a certain distance. This distance is detected and controlled by a rotary encoder mounted on the fourth sprocket 28. Once a set number of cartons have been collected or the current production batch has ended, the first telescopic fork structure 31 lowers the pallet 1 and the collected cartons to a fixed picking position. This picking position is controlled by a proximity switch and is associated with the AGV trolley's picking position to ensure that the AGV trolley picks up goods at the accurate location. The controller can be a PLC controller.

[0058] Specifically, during the production process, each filament production line produces a maximum of 5 batches per shift. By adding a pallet set buffer function to the cardboard box recycling device, the system can replenish an empty pallet set (5 pallets) at most once per production shift. Therefore, the workflow for cardboard box recycling in this application can be divided into two scenarios:

[0059] 1. No empty pallets in support component 5: After the production task of this batch is completed, the full carton pallet 1 is retrieved and the AGV interacts with the AGV. At this time, there are no empty pallets in the first storage area. The AGV runs to the storage point of pallet group 1 and takes 1 set of empty pallets (5 pieces). It runs to the outside of electric door 55. The controller receives the signal and controls electric door 55 to open automatically. The AGV replenishes the empty pallet group to the first storage area, and then takes out the full carton pallet 1. Electric door 55 closes automatically. The unpacking system starts the next batch of production. The AGV transports the full carton pallet 1 to the storage point.

[0060] 2. Empty pallet in support component 5: After the production task of this batch is completed, the full carton pallet 1 is retrieved and the AGV interacts with it. At this time, there is a buffer empty pallet in the carton palletizer. The AGV trolley runs to the electric door 55. The controller receives the signal and controls the electric door 55 to open automatically. The AGV trolley takes out the full carton pallet 1. The electric door 55 closes automatically. The unpacking system starts the next batch of production. The AGV transports the full carton pallet 1 to the storage point.

[0061] Specifically, by optimizing the workflow, when there is no empty pallet buffer within the support component 5, the two actions of temporarily placing the empty pallet group and the full carton pallet 1 outside the electric gate 55 are reduced. When there are empty pallets within the support component 5, the actions of retrieving empty pallets from the fixed station, temporarily placing the empty pallet group and the full carton pallet 1 outside the electric gate 55, and releasing the empty pallets are reduced. This workflow optimization reduces multiple repetitive steps, significantly improving the efficiency of carton recycling.

[0062] Specifically, this application includes an empty pallet forklift function, a lifting function, a carton straightening function, and an automatic door function. The process for the carton recycling task in this application is as follows: The equipment is turned on; it is determined whether there is a buffer empty pallet. If it is determined that there is no buffer empty pallet, a warning signal is issued to remind to replenish the empty pallet, the electric door 55 is opened, an empty pallet is replenished, and the electric door 55 is closed; if it is determined that there is a buffer empty pallet, the first telescopic fork structure 31 picks up one empty pallet and moves it to the working starting position to wait; the unpacking system starts production. After the cartons on the pallet 1 are stacked to the set height, the first telescopic fork structure 31 descends a fixed distance, straightening one carton at a time; the current batch of production ends; the first telescopic fork structure 31 descends to the full pallet 1 picking position; the electric door 55 opens, the AGV trolley takes away the full carton pallet 1, and the electric door 55 closes; waiting for the next batch of production to begin.

[0063] Specifically, the empty pallet replenishment and buffering system is designed with 5 empty pallets per group. To facilitate the AGV's transport of empty pallet groups and the retrieval of full carton pallets after production, and to meet buffering requirements with maximum safety based on the existing carton stacking height, the empty pallet replenishment location is designed to be placed directly on the ground, i.e., a first storage area is set up on the ground. Five sets of diffuse reflection photoelectric switches are also installed at the empty pallet storage location, corresponding one-to-one with the positions of the five pallets in the pallet group 1 in the height direction, used to detect the number of empty pallets in the buffer position. When using the empty pallet group, individual empty pallets are picked up from top to bottom. The picking function uses a telescopic fork mechanism commonly used in stacker cranes, with one set of first telescopic fork structures 31 on each side, employing a cantilever beam structure. Each set of first telescopic fork structures 31 uses a reducer, a transmission gear and rack mechanism, a chain-type two-stage differential telescopic mechanism, and a slider mechanism to achieve the picking up and separating of empty pallets. The stroke of the first telescopic fork structure 31 is controlled by multiple sets of proximity switches. After the first telescopic fork structure 31 retracts, the distance between the left and right forks is greater than the maximum length of the stacked cartons.

[0064] Specifically, the lifting mechanism 2 is driven by a first drive motor 21 controlled by a frequency converter, which drives a chain transmission mechanism to move the first telescopic fork structures 31 on both sides vertically along the slide rail 57, controlling both vertical movement and speed. Vertical lifting is controlled by a combination of a proximity switch and an encoder on the second rotating shaft 210. The proximity switch is used to set the origin height, the initial height for carton stacking, and the height for picking up a full pallet 1 in the vertical lifting direction. The encoder is used to detect and set the descent distance during carton stacking and the height at which the first telescopic fork structure 31 picks up an empty pallet. The first drive motor 21 can be a geared motor.

[0065] Specifically, this application uses the straightening component 4 to straighten the cartons, resulting in a very flat stacking shape for full carton pallets 1, which meets the requirements for automatic transport by the AGV. The lifting component 2 and the load-bearing component 3 can buffer one pallet group (5 pallets 1), while also enabling the AGV to automatically replenish pallets 1 and pick up full carton pallets 1. Through equipment parameter adjustment, the electric door 55 and the AGV achieve information interaction, and the coordinated lifting and extending actions of the first telescopic fork structure 31 enable the automatic retrieval of empty pallet groups from top to bottom. This application operates smoothly during use, with good carton straightening function and relatively accurate lifting and positioning, optimizing the carton recycling process.
