Abstract
Description
Technical Field
[0001] This utility model relates to the field of logistics palletizing, and in particular to an automatic palletizing device for logistics. Background Technology
[0002] In the logistics and warehousing sector, automated palletizing equipment is a core component for achieving efficient stacking of goods and reducing labor costs. Existing palletizing equipment generally uses mechanical grippers as the holding mechanism, employing pneumatic or electric drives to grasp and transport goods.
[0003] Traditional grippers rely solely on the friction between the clamping plate and the box to secure goods. The mechanical gripping force is concentrated in a localized area of the box, which can easily damage the box during handling. For thin or fragile boxes (such as corrugated boxes), dents or breaks can occur, affecting the integrity of the goods. Therefore, we propose an automatic palletizing device for logistics. Utility Model Content
[0004] To address the technical problem that grippers can easily damage cartons when handling goods, this utility model provides an automatic palletizing device for logistics.
[0005] The present invention is achieved by the following technical solution: an automatic palletizing device for logistics, including a support frame for supporting the device, a working motor installed on the outside of the support frame, and a rotating screw connected to the output end of the working motor;
[0006] The rotating screw has a threaded surface through which a moving block passes. A limit rod passes through the inside of the moving block. Both ends of the limit rod are fixed to the support frame. An electric push rod is connected to the bottom of the moving block. The bottom of the electric push rod is connected to the connecting frame on the cargo clamping mechanism.
[0007] The working motor drives the rotating screw to rotate, which in turn moves the moving block laterally along the rotating screw, positioning the cargo clamping mechanism above the cargo to be clamped.
[0008] Vertical lifting: The electric push rod controls the lifting height of the cargo clamping mechanism to adapt to the needs of different stacking layers or cargo heights.
[0009] The cargo clamping mechanism includes a connecting frame, with a drive motor connected to the bottom of the connecting frame. Both the working motor and the drive motor are reversible motors. A connecting screw is connected to the output end of the drive motor, and a limiting sleeve is installed at the other end of the connecting screw. The limiting sleeve is installed at the bottom of the connecting frame. A sliding block is threaded onto the surface of the connecting screw, and a clamping rod is fixedly connected to the bottom end of the sliding block. A clamping frame is fixedly connected to the outer side of the bottom end of the clamping rod. A negative pressure pump is installed inside the clamping frame, and one end of a negative pressure pipe is connected to the outer side of the negative pressure pump. The other end of the negative pressure pipe is connected to a negative pressure suction head.
[0010] The negative pressure pump inside the clamping frame starts, and multiple sets of negative pressure suction heads connected through negative pressure pipes generate suction force, tightly adhering to the surface of goods, especially smooth or fragile packaging such as cardboard boxes and plastic boxes, forming a dual fixation of mechanical clamping and vacuum suction. The clamping frame, through the combined action of the mechanical clamping force of the clamping rods and the suction force of the negative pressure suction heads, ensures that the goods do not slip or shift under high-speed movement or vibration.
[0011] As a further optimization of this utility model, the drive motor drives the sliding block to move along the axial direction of the connecting screw through the connecting screw, thereby driving the two sets of clamping rods to slide inward or outward synchronously, so that the clamping frame forms a clamping space and wraps the two sides of the goods.
[0012] As a further optimization of this utility model, multiple sets of negative pressure suction heads are provided and evenly installed on the clamping frame; the even arrangement of multiple sets of negative pressure suction heads can adapt to goods of different sizes and surface characteristics, ensuring maximum adsorption coverage area.
[0013] As a further optimization of this utility model, the clamping rods are provided in two opposing sets, and the two sets of clamping frames installed on the two sets of clamping rods form a cargo clamping space.
[0014] As a further optimization of this utility model, the working motor works in conjunction with the electric push rod to move the goods to the target palletizing position, and the stacking height and arrangement are controlled by a preset program to achieve automated palletizing.
[0015] As a further optimization of this utility model, after the goods arrive at the designated position, the negative pressure pump is turned off, and the negative pressure suction head releases the goods; the drive motor rotates in the opposite direction, driving the clamping rod to expand and reset, preparing for the next clamping cycle.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. This utility model utilizes the combined action of mechanical clamping and negative pressure adsorption. The clamping rods of the clamping frame apply uniform mechanical pressure to both sides of the goods, while the negative pressure suction head generates adsorption force to adhere to the surface of the goods. This dual fixing mechanism effectively solves the problem of slippage on smooth surfaces such as plastic boxes.
[0018] 2. This utility model avoids the pitting or damage to the box caused by the local pressure of traditional mechanical grippers by evenly distributing the clamping force and adsorption force, especially for fragile goods such as corrugated cardboard boxes and thin-walled plastic boxes.
[0019] 3. This utility model uses multiple sets of negative pressure suction heads evenly arranged to adapt to goods of different sizes and surface characteristics, ensuring maximum adsorption coverage area.
[0020] In summary, this utility model significantly improves the clamping stability of smooth, irregularly shaped, or fragile boxes through the synergistic effect of mechanical clamping and negative pressure adsorption. The clamping force is evenly distributed, avoiding deformation or damage to goods caused by local pressure. Attached Figure Description

Detailed Implementation
[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0028] Example 1: Please refer to Figures 1-4 This embodiment proposes an automatic palletizing device for logistics, including a support frame 1 for supporting the device, a working motor 2 installed on the outside of the support frame 1, and a rotating screw 3 connected to the output end of the working motor 2.
[0029] The rotating screw 3 has a threaded surface through which a moving block 4 passes. The inner side of the moving block 4 slides through a limit rod 31. Both ends of the limit rod 31 are fixed on the support frame 1. The bottom end of the moving block 4 is connected to an electric push rod 41. The bottom end of the electric push rod 41 is connected to a connecting frame 51 on the cargo clamping mechanism 5.
[0030] Furthermore, the working motor 2 drives the rotating screw 3 to rotate, causing the moving block 4 to move laterally along the rotating screw 3, so that the cargo clamping mechanism 5 is positioned above the cargo to be clamped.
[0031] Vertical lifting: The electric push rod 41 controls the lifting height of the cargo clamping mechanism 5 to adapt to the needs of different stacking layers or cargo heights.
[0032] Furthermore, the working motor 2 works in conjunction with the electric push rod 41 to move the goods to the target palletizing position, and controls the stacking height and arrangement through a preset program to achieve automated palletizing.
[0033] The cargo clamping mechanism 5 includes a connecting frame 51, with a drive motor 52 connected to the bottom end of the connecting frame 51. Both the working motor 2 and the drive motor 52 are forward and reverse rotating motors. The output end of the drive motor 52 is connected to a connecting screw 53, and a limiting sleeve 54 is installed at the other end of the connecting screw 53. The limiting sleeve 54 is installed at the bottom of the connecting frame 51. A sliding block 55 is threaded onto the surface of the connecting screw 53. A clamping rod 56 is fixedly connected to the bottom end of the sliding block 55, and a clamping frame 57 is fixedly connected to the outer side of the bottom end of the clamping rod 56.
[0034] Specifically, the drive motor 52 drives the sliding block 55 to move axially along the connecting screw 53 via the connecting screw 53, causing the two sets of clamping rods 56 to slide inward or outward simultaneously, so that the clamping frame 57 forms a clamping space to wrap around both sides of the goods.
[0035] It should be noted that the clamping rods 56 are provided in two opposing sets, and the two sets of clamping frames 57 installed on the two sets of clamping rods 56 form a cargo clamping space.
[0036] A negative pressure pump 58 is installed on the inner side of the clamping frame 57, and one end of a negative pressure pipe 59 is connected to the outer side of the negative pressure pump 58. The other end of the negative pressure pipe 59 is connected to a negative pressure suction head 510.
[0037] Furthermore, multiple sets of negative pressure suction heads 510 are provided and evenly installed on the clamping frame 57; the even arrangement of multiple sets of negative pressure suction heads 510 can adapt to goods of different sizes and surface characteristics, ensuring maximum adsorption coverage area.
[0038] Furthermore, the negative pressure pump 58 inside the clamping frame 57 is activated, and multiple sets of negative pressure suction heads 510 connected through the negative pressure pipe 59 generate suction force, tightly adhering to the surface of the goods, especially smooth or fragile packaging such as cardboard boxes and plastic boxes, forming a dual fixation of mechanical clamping and vacuum suction. The clamping frame 57, through the combined action of the mechanical clamping force of the clamping rod 56 and the suction force of the negative pressure suction heads 510, ensures that the goods do not slip or shift under high-speed movement or vibration environments.
[0039] After the goods arrive at the designated location, the negative pressure pump 58 is turned off, and the negative pressure suction head 510 releases the goods; the drive motor 52 rotates in the opposite direction, driving the clamping rod 56 to expand and reset, preparing for the next clamping cycle.
[0040] Working principle:
[0041] This utility model of an automatic palletizing device for logistics achieves efficient and stable cargo clamping and precise palletizing through the synergistic effect of the cargo clamping mechanism 5 and the negative pressure adsorption system. Its specific workflow is as follows:
[0042] Horizontal movement: The working motor 2 drives the rotating screw 3 to rotate, which in turn drives the moving block 4 to move laterally along the rotating screw 3, so that the cargo clamping mechanism 5 is positioned above the cargo to be clamped.
[0043] Vertical lifting: The electric push rod 41 controls the lifting height of the cargo clamping mechanism 5 to adapt to the needs of different stacking layers or cargo heights.
[0044] Clamping action execution:
[0045] Gripper opening and closing control: Drive motor 52 drives sliding block 55 to move axially along connecting screw 53 via connecting screw 53, causing two sets of gripping rods 56 to slide inward or outward synchronously, so that gripping frame 57 forms a gripping space to wrap both sides of the goods.
[0046] Negative pressure adsorption start-up: The negative pressure pump 58 inside the clamping frame 57 is started, and multiple sets of negative pressure suction heads 510 connected through the negative pressure pipe 59 generate adsorption force, which tightly adheres to the surface of the goods, especially smooth or fragile packaging such as cardboard boxes and plastic boxes, forming a dual fixation of mechanical clamping and vacuum adsorption.
[0047] Cargo handling and palletizing:
[0048] The clamping frame 57, through the combined action of the mechanical clamping force of the clamping rod 56 and the adsorption force of the negative pressure suction head 510, ensures that the goods do not slip or deviate in high-speed movement or vibration environments.
[0049] The working motor 2 works in conjunction with the electric push rod 41 to move the goods to the target palletizing position. The stacking height and arrangement are controlled by a preset program to achieve automated palletizing.
[0050] Release and reset:
[0051] Adsorption release: After the goods reach the designated location, the negative pressure pump 58 is turned off, and the negative pressure suction head 510 releases the goods;
[0052] Gripper reset: Drive motor 52 rotates in the opposite direction, driving gripping rod 56 to expand and reset, preparing for the next gripping cycle.
[0053] The synergistic effect of mechanical clamping and negative pressure adsorption significantly improves the clamping stability of smooth, irregularly shaped or fragile boxes, and the clamping force is evenly distributed to avoid deformation or damage to goods caused by local pressure.
[0054] Multiple sets of negative pressure suction heads 510 are evenly arranged, which can adapt to goods of different sizes and surface characteristics to ensure maximum adsorption coverage area.
