Description

Technical Field

[0001] This utility model relates to the field of sorting, and in particular to sorting ports. Background Technology

[0002] The standard product inbound and outbound process involves palletized inbound and outbound operations. Depending on the industry characteristics, a pallet may contain 50 layers (Tray height 500mm) or 5 layers (BOX height 450mm). The trays contain thin sheets, stacked one layer on top of the other. The BOX contains five sealed, packaged products stacked together. The software then issues a task to store the entire pallet on the shelf. If the order requires the products from two or more layers to be shipped out, the software needs to issue the entire pallet out sequentially. This will affect and consume the AGV's time and the manual sorting time.

[0003] Observation revealed stacking gaps between layers, leading to the decision to use a clamping arm method to separate finished products. Two workstations were set up, with the sorting mechanism responsible for moving pallets or trays layer by layer to change the product's position. This process can be completed within the warehouse without requiring outbound shipment. After sorting, the stacker crane loads the products that need to be shipped out and places them at the port exit, while those that do not need to be shipped out remain temporarily stored in the warehouse. This reduces the number of devices used and minimizes errors caused by finished products and manual intervention for the company. Utility Model Content

[0004] The purpose of this invention is to provide a sorting port to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sorting port, including a frame and a horizontal moving mechanism, a lifting mechanism and a clamping unit disposed on the frame; The horizontal movement mechanism includes a horizontal traverse servo motor, a synchronous belt driven by the horizontal traverse servo motor, and two sets of horizontal linear sliders arranged parallel to each other on both sides of the synchronous belt. The lifting mechanism includes a lifting linear slider that is fixedly connected to a synchronous belt via a connecting block. The lifting linear slider slides in cooperation with a horizontal linear slider. The lifting mechanism also includes a lifting servo motor and a lifting ball screw driven by the lifting servo motor. The clamping unit includes a mounting plate and a clamping arm. The mounting plate is connected to the lifting ball screw via a nut seat. The clamping arm is slidably connected to the mounting plate. The clamping unit also includes a drive unit for driving the clamping arm to perform opening and closing movements.

[0006] Preferably, both ends of the horizontal linear slider are provided with horizontal limiting blocks, which are fixedly installed on the frame to limit the horizontal movement of the lifting linear slider.

[0007] Preferably, the top of the lifting linear slider is equipped with two sets of upper limiting blocks, which are used to limit the vertical movement stroke of the lifting linear slider.

[0008] Preferably, the bottom end of the lifting ball screw is rotatably connected to a bearing seat via a bearing, and the bearing seat is fixedly installed on the lifting linear slider.

[0009] Preferably, a nut seat that is threadedly engaged with the lifting ball screw is fixedly installed on the back of the mounting plate, and a lifting sliding block that is slidably connected to the lifting linear slider is also installed on the back of the mounting plate.

[0010] Preferably, guide rails are fixedly installed on both sides of the front of the mounting plate, and a horizontal sliding block is slidably connected to each guide rail. A connecting plate is installed on the horizontal sliding block, and the clamping arm is fixedly installed on the connecting plate.

[0011] Preferably, the clamping arm has a protruding locking block on one side facing the tray, and the tray has a corresponding slot that matches the locking block.

[0012] Preferably, the frame is provided with a support base corresponding to both the first and second workstations, and the support base is used to support the pallet.

[0013] Preferably, the drive unit includes a mounting base fixedly mounted on the mounting plate, and two clamping cylinders are mounted on the mounting base. The output end of each clamping cylinder is provided with a piston rod, and the piston rod is connected to the corresponding connecting plate through a connecting seat to drive the clamping arm to move in opposite directions or in opposite directions along the guide rail.

[0014] The technical effects and advantages of this utility model are as follows: 1. Achieve precise in-warehouse sorting, significantly improving logistics efficiency: By installing automated pallet unpacking mechanisms at internal warehouse ports, on-demand sorting of entire pallets of goods can be completed directly within the warehouse. Only the layers requiring outbound shipment need to be moved to the outbound workstation, while layers not requiring outbound shipment are temporarily stored in the in-warehouse workstation. This avoids the redundant operation of outbounding entire pallets of goods just to sort a few layers, greatly freeing up the capacity of high-end logistics equipment such as stacker cranes and AGVs, allowing them to focus on pure handling tasks, resulting in a qualitative improvement in overall logistics efficiency.

[0015] 2. Reduce human intervention and improve operational accuracy and reliability: The entire sorting process is completed automatically by the equipment, eliminating the manual sorting link and fundamentally avoiding problems such as incorrect material selection, omission, and inaccurate inventory information caused by human error.

[0016] 3. Optimize spatial layout and reduce overall costs: Since sorting operations are completed inside the warehouse, there is no need to set up a separate sorting area outside the warehouse, which saves valuable production or storage space, optimizes the spatial layout, and at the same time reduces the reliance on AGVs and manual labor, effectively reducing the company's equipment investment and long-term operating labor costs.

[0017] 4. Employing high-precision transmission components such as servo motors, lifting ball screws, and linear guides ensures accurate positioning of the gripping mechanism in both horizontal and vertical directions, effectively resolving product collision issues caused by insufficient precision. Through dual-station collaborative operation and programmed process control, smooth and reliable sorting operations are achieved, addressing technical shortcomings in earlier control systems and guaranteeing operational stability and reliability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figures 1-7 The sorting port shown includes a frame 9 and a horizontal moving mechanism, a lifting mechanism and a clamping unit 7 disposed on the frame 9; The horizontal movement mechanism includes a horizontal traverse servo motor 2, a synchronous belt 3 driven by the horizontal traverse servo motor 2, and two sets of horizontal linear sliders 4 arranged parallel to each other on both sides of the synchronous belt 3. The lifting mechanism includes a lifting linear slider 5 fixedly connected to the synchronous belt 3 via a connecting block. The lifting linear slider 5 slides with the horizontal linear slider 4. The lifting mechanism also includes a lifting servo motor 1 and a lifting ball screw 11 driven by the lifting servo motor 1. The clamping unit 7 includes a mounting plate 71 and a clamping arm 76. The mounting plate 71 is connected to the lifting ball screw 11 via a nut seat 73. The clamping arm 76 is slidably connected to the mounting plate 71. The clamping unit 7 also includes a drive unit 8 for driving the clamping arm 76 to perform opening and closing movements.

[0022] Through the coordinated operation of the horizontal moving mechanism, the lifting mechanism and the clamping unit 7, the pallet 6 placed on the first and second workstations is clamped, transferred and placed.

[0023] Workstation 1 and Workstation 2 are used to buffer the moving tray 6, with enough space to stagger their positions.

[0024] The lifting servo motor 1 drives the lifting ball screw 11 to rotate, turning its rotational motion into vertical lifting motion, so as to lift and remove the pallet 6 at any position. Because there are many product choices for servo motors in the domestic and foreign markets, such as Siemens, Panasonic, BKO, Xinje, etc.

[0025] The horizontal traverse servo motor 2 drives the synchronous pulley to drive the synchronous belt 3, so that its rotational motion is converted into horizontal linear motion.

[0026] The horizontal transverse synchronous belt 3 is made of polyurethane with steel wire inside, fused together. The inner side has corresponding toothed shape to prevent slippage and to withstand greater torque.

[0027] The horizontal linear slider 4 ensures its running accuracy and is also an important part supporting the entire mechanism.

[0028] The linear slider 5 ensures the accuracy of the lifting dimensions and is also an important part supporting the entire lifting mechanism. Brands include Yiheda and Hiwin.

[0029] The lifting ball screw 11 is formed by rolling or cutting. It has high surface hardness and large load capacity. By changing its processing technology, screws with different precision can be obtained.

[0030] The clamping unit 7 is made of square tubing welded to iron plate to increase its strength. It can also be made by CNC machining. The two processes have a large difference in precision, so the choice depends on the specific situation.

[0031] Both ends of the horizontal linear slider 4 are provided with horizontal limiting blocks 41, which are fixedly installed on the frame 9 to limit the horizontal movement of the lifting linear slider 5.

[0032] The horizontal limiting block 41 ensures that the horizontal mechanism will not exceed the entire frame 9 in the event of failure, serving as the last line of defense for the entire mechanism.

[0033] Two sets of upper limiting blocks 51 are installed at the top of the lifting linear slider 5. The upper limiting blocks 51 are used to limit the vertical movement stroke of the lifting linear slider 5.

[0034] When the lifting servo motor 1 is started to control the lifting ball screw 11 to perform transmission, the clamping unit 7 is driven to slide vertically along the lifting linear slider 5 under the action of the lifting ball screw 11. When the clamping unit 7 moves and the clamping tray 6 moves with the drive unit 8 to contact the upper limit block 51, the vertical movement of the clamping unit 7 is at its maximum stroke.

[0035] When the horizontal traverse servo motor 2 is started, the synchronous belt 3 is controlled to drive the lifting linear slider 5 connected to it to slide horizontally along the horizontal linear slider 4 under the action of the synchronous belt 3. This causes the clamping unit 7 connected to the lifting linear slider 5 to move horizontally as well. When the lifting linear slider 5 moves and contacts the horizontal limiting block 41, it moves to the maximum stroke.

[0036] When core sorting processes are required: The horizontal traverse servo motor 2 is started and driven by the synchronous belt 3, which drives the lifting linear slider 5 to slide horizontally along the horizontal linear slider 4, so as to precisely move the clamping unit 7 and the drive unit 8 on the lifting linear slider 5 above the second work station.

[0037] The lifting servo motor 1 drives the lifting ball screw 11, which in turn drives the clamping unit 7 and the drive unit 8 to descend. The target height of the descent corresponds to the height of the specified tray 6. The precise control of the servo motor ensures the positioning accuracy.

[0038] When the clamping cylinder 82 is vented, the piston rod 83 extends, and the two clamping arms 76 on the left and right sides open through the connecting seat 84, with a width greater than that of the tray 6.

[0039] When the clamping arm 76 is in the open state, the lifting servo motor 1 drives the lifting ball screw 11 to continue to descend slightly, so that the front end of the open clamping arm 76 enters the target gap.

[0040] When the clamping cylinder 82 is activated, the piston rod 83 retracts, pulling the clamping arm 76 to close, supporting the upper-layer tray 6 that needs to be separated from below. For example, if the first-layer tray 6 needs to be separated, this first cycle supports all trays 6 from the first layer and above. If the second-layer tray 6 needs to be separated, this first cycle supports all trays 6 from the second layer and above, and so on.

[0041] The lifting servo motor 1 reverses, and the ball screw 11 lifts the entire clamping arm 76 and the supported tray 6 by a small distance, such as a few millimeters, so that it is completely separated from the tray 6 below and the stacking pressure is eliminated.

[0042] The horizontal traverse servo motor 2 starts and drives the lifting linear slider 5 to slide horizontally along the horizontal linear slider 4 via the synchronous belt 3, moving the clamping module clamping unit 7 holding the pallet 6 from above the workstation 2 to above the workstation 1.

[0043] The lifting servo motor 1 drives the clamping arm 76 to descend, placing the tray 6 sets smoothly on the support seat 61 of workstation one.

[0044] The clamping cylinder 82 opens again, the clamping arm 76 separates from the tray 6, and then the lifting mechanism raises the clamping arm 76 to the designated height, ready for the next operation; At this time, the clamping cylinder 82 is activated, the piston rod 83 retracts, and the clamping arm 76 is pulled to close, supporting the upper pallet 6 that needs to be separated from below. If the pallet 6 to be placed is the first pallet 6, the clamping arm 76 moves to the target gap of the second pallet 6. By moving the second pallet 6 to station two, the first pallet 6 that needs to be separated is placed on station one.

[0045] Loop condition and continuation: At this point, workstation one has the first layer of tray 6, while workstation two has trays 6 starting from the second layer.

[0046] Based on the task order, the system determines that: Next, repeat the above steps, extract the pallets 6 that need to be shipped out from the remaining pallet 6 pile at workstation 2, transfer them to workstation 1, and recombine the pallets 6 that need to be shipped out and the pallets 6 that need to be temporarily stored at workstation 1 and workstation 2 respectively.

[0047] The bottom end of the lifting ball screw 11 is rotatably connected to a bearing seat 12 via a bearing, and the bearing seat 12 is fixedly installed on the lifting linear slider 5.

[0048] The transmission stability of the lifting ball screw 11 is ensured by the bearing seat 12. The lifting ball screw 11 is controlled by the lifting servo motor 1, which drives the clamping unit 7 to a vertical position along the lifting linear slider 5, and at the same time, it moves horizontally along the horizontal linear slider 4 along with the lifting linear slider 5.

[0049] Example 1: A nut seat 73 that is threadedly engaged with the lifting ball screw 11 is fixedly installed on the back of the mounting plate 71. A lifting sliding block 74 that is slidably connected to the lifting linear slider 5 is also installed on the back of the mounting plate 71.

[0050] Guide rails 72 are fixedly installed on both sides of the front of the mounting plate 71. A horizontal sliding block 75 is slidably connected to each guide rail 72. A connecting plate 77 is installed on the horizontal sliding block 75. The clamping arm 76 is fixedly installed on the connecting plate 77.

[0051] The horizontal sliding block 75 slides along the guide rail 72, ensuring the stability of the horizontal sliding block 75, thereby improving the stability of the sliding of the clamping arm 76 installed with the horizontal sliding block 75 via the connecting plate 77, and thus ensuring the stability of the clamping arm 76 in clamping the pallet 6.

[0052] The clamping arm 76 has a protruding locking block 761 on one side facing the tray 6, and the corresponding position of the tray 6 has a locking groove 62 that matches the locking block 761.

[0053] By controlling the lifting servo motor 1 to drive the lifting ball screw 11, the clamping unit 7 and the driving unit 8 are lowered. The target height of the descent corresponds to the height of the specified tray 6, so that the card block 761 on the clamping arm 76 corresponds to the card slot 62 on the specified tray 6. When the clamping cylinder 82 is activated, the piston rod 83 retracts, pulling the clamping arm 76 to close. By controlling the clamping arm 76 to move towards the tray 6, the locking block 761 is inserted into the locking groove 62. At this time, the clamping arm 76 is docked with the tray 6, and the tray 6 can be held. The clamping arm 76 holds the tray 6 to be separated and all the trays 6 above it.

[0054] The frame 9 is equipped with support bases 61 corresponding to the first and second workstations. The support bases 61 are used to support the pallet 6, which facilitates the placement of the pallet 6.

[0055] Example 2: The drive unit 8 includes a mounting base 81 fixedly mounted on the mounting plate 71. Two clamping cylinders 82 are mounted on the mounting base 81. The output end of the clamping cylinder 82 is provided with a piston rod 83. The piston rod 83 is connected to the corresponding connecting plate 77 through the connecting seat 84 to drive the clamping arm 76 to move in opposite directions or away from each other along the guide rail 72.

[0056] By actuating the clamping cylinder 82, the piston rod 83 retracts, driving the connecting seat 84 to pull the connecting plate 77, which in turn drives the horizontal sliding block 75 to slide along the guide rail 72. At the same time, the movement of the connecting plate 77 causes the clamping arm 76 to close, thus clamping the tray 6. The action of the clamping cylinder 82 causes the piston rod 83 to extend, which in turn causes the connecting seat 84 to push the connecting plate 77 to drive the horizontal sliding block 75 to slide along the guide rail 72. At the same time, the movement of the connecting plate 77 pushes the clamping arm 76 to open, causing the clamping arm 76 to separate from the tray 6.

[0057] The clamping cylinder 82 is used to clamp and release, ensuring that a certain gap is maintained between the clamping arm 76 and the tray 6 when the clamping arm 76 descends. This prevents the tray 6 from colliding with the clamp due to insufficient positioning or installation position, which could lead to accidents or damage. There are also many brands on the market that can replace it, such as SMC and Airtac.

[0058] Production issues warehousing tasks from the software. The stacker crane takes the corresponding pallet 6 from the warehouse to workstation 2 according to the task issued by the software. At this time, the stacker crane is not affected by the unpacking mechanism and can continue to perform other inbound and outbound tasks. The horizontal traverse servo motor drives the horizontal traverse 2, and the synchronous belt 3 realizes the stacking and unpacking actions of station one and station two. Depending on the different unpacking tasks, the unpacking actions of the mechanism will also be different. After the task is completed, the stacker will store the pallet 6 of station one into the warehouse, and the pallet 6 of station two will be placed at the warehouse exit, and picked up by AGV or manual. At this point, the unpacking action is completed.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
