Description

Technical Field

[0001] This utility model relates to the field of lid packaging technology, and in particular to a lid boxing device. Background Technology

[0002] After mass production, the lids need to be boxed and packaged, with multiple lids stacked layer by layer inside a box. During production, the lids arrive in 6x8 arrays (48 lids / batch), while standard packaging boxes use an 8x8 single-layer structure (64 lids / layer). Direct boxing results in a single-layer space utilization rate of only 75%, creating a gap of 16 lid slots. This not only creates 25% of ineffective transportation space and increases logistics costs, but also causes lid wear and damage due to vibrations during transportation, leading to packaging breakage. Furthermore, it generates a chain reaction of increased filler consumption, repetitive manual handling, and a decreased customer acceptance experience. Essentially, this is a systemic efficiency loss caused by the mismatch between production batches and standard container specifications.

[0003] Therefore, it is necessary to provide a lid packing device that can match the lids of the production batch with the packing specifications. Utility Model Content

[0009] Preferably, the material handling robot includes a material handling moving drive mechanism and a material handling suction unit. The material handling moving drive mechanism is disposed on the frame, and the material handling suction unit is disposed on the material handling moving drive mechanism. The material handling moving drive mechanism is used to drive the material handling suction unit to move, and the material handling suction unit is used to pick up a plurality of the lids in a horizontal direction.

[0010] Preferably, the loading transfer robot includes a loading transfer frame, a loading transfer rotary drive mechanism, and a loading transfer suction unit. The loading transfer frame is mounted on the machine frame, the loading transfer rotary drive mechanism is mounted on the loading transfer frame, and a plurality of loading transfer suction units are rotatably connected to the loading transfer frame. The loading transfer rotary drive mechanism is connected to each of the loading transfer suction units. The loading transfer suction units are used to pick up the cover on the suction unit. The loading transfer rotary drive mechanism drives each loading transfer suction unit to rotate, so that the loading transfer suction unit drives the lid to rotate, thereby making the bottom outer side of the cover face the flipping loading robot.

[0011] Preferably, the lid packing equipment further includes an injection molding machine, which is located on one side of the material handling robot. The injection molding machine is used to injection mold the lids, and the material handling robot can move into the injection molding machine and transport the lids inside the injection molding machine to one side of the loading transfer robot.

The flipping drive mechanism is mounted on the frame, the retractable movement drive mechanism is mounted on the flipping drive mechanism, and a plurality of flipping transfer suction units are arranged side by side on the retractable movement drive mechanism. The flipping transfer suction units are used to suction a target number of lids from the conveying channel.

[0015] Compared with existing technologies, the lid packing equipment of this utility model achieves precise lid positioning through the linkage of the conveyor channel divided by partitions and the flipping transfer robot, as well as the cooperation of the baffle and the conveyor channel. This ensures that the lids being packed accurately match the standard box specifications, such as an 8×8 array (64 pieces / layer), increasing the existing packing density from 75% to 100%, completely eliminating transportation gaps, reducing ineffective space loss by 25%, and thus matching the lids of the production batch with the box specifications. The improved space utilization directly reduces the frequency of transportation, and the filler-free design reduces packaging material costs. At the same time, it avoids manual handling, saving secondary operation costs. The equipment compatibility design can adapt to different box specifications. Secondly, the lid packing equipment of this invention uses a flipping loading robot to flip the lids with their openings facing downwards and place them in the respective conveying channels of the loading conveyor. This ensures that the loading conveyor transports lids with their openings facing downwards, guaranteeing the stability of lid transport. When the lids are transported to the unloading conveyor, they are arranged closely together in each conveying channel under the action of the baffles, which helps to reduce the gaps between lids during subsequent unloading and facilitates subsequent lid packing. Furthermore, by flipping the lids with the flipping transfer robot, the flipping unloading robot can pick up the lids from the flipping transfer robot and flip the lids with their openings facing upwards. This facilitates stacking and packing the lids with their openings facing upwards, thus helping to protect the lid openings of the packed lids. At the same time, precise control of the lid opening direction ensures stacking stability. Attached Figure Description

[0026] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0027] Please see Figures 1 to 9 The lid packing equipment 100 of this utility model includes a frame 1, a feeding conveying mechanism 2, partitions 23, baffles 24, a feeding module 3, a flipping feeding robot 4, a flipping transfer robot 5, and a flipping unloading robot 6. The feeding conveying mechanism 2 is mounted on the frame 1 and has a feeding conveying position 21 and an unloading conveying position 22 along its conveying direction. The feeding conveying mechanism 2 is used to convey lids from the feeding conveying position 21 to the unloading conveying position 22. Several partitions 23 are respectively arranged above the feeding conveying mechanism 2 along its conveying direction, and adjacent partitions 23 are arranged at intervals to divide the conveying space above the feeding conveying mechanism 2 into several conveying channels 231. The baffles 24 are arranged above the feeding conveying mechanism 2 and located at the unloading conveying position 22. 24 is inserted into each conveying channel 231 and used to block the cover; the feeding module 3 is set on the frame 1 and is used to provide the cover; the flipping loading robot 4 is set on the frame 1 and located on one side of the feeding module 3. The flipping loading robot 4 is used to pick up the cover on the feeding module 3 and flip the cover opening downwards and place it in each conveying channel 231 of the loading conveying position 21; the flipping transfer robot 5 is set on the frame 1 and is used to pick up the target number of covers in each conveying channel 231 of the unloading conveying position 22 and flip the cover; the flipping unloading robot 6 is set on the frame 1 and located on one side of the flipping transfer robot 5. The flipping unloading robot 6 is used to pick up the cover on the flipping transfer robot 5 and flip the cover opening upwards to unload and pack the cover into a box.

[0028] The lid packing equipment 100 of this utility model uses a flipping loading robot 4 to flip the lids with their openings facing downwards and place them in the conveying channels 231 of the loading conveyor 21. This ensures that the loading conveyor 2 transports lids with their openings facing downwards, guaranteeing the stability of the lid transport. When the lids are transported to the unloading conveyor 22, the lids in each conveying channel 231 are arranged closely together under the action of the baffles 24, which helps to reduce the gaps between the lids during subsequent unloading. The conveying channels 231 divided by the partition 23 are linked with the flipping transfer robot 5, and the baffles 24 cooperate with the conveying channels 231 to achieve precise positioning of the lids. This ensures that the unloaded and packed lids accurately match the specification array of the standard box, thereby matching the lids of the production batch with the box specifications. The number of conveying channels 231 multiplied by the target number of lids picked up by the flipping transfer robot 5 in a single row of conveying channels 231 represents the specification array of the box. By flipping the transfer robot 5 and flipping the lid, the flipping unloading robot 6 can pick up the lid from the flipping transfer robot 5 and flip the lid opening upwards, which helps to stack and pack the lids with the opening facing upwards.

[0029] Please see Figure 2 and Figure 6 In one embodiment, the gap between two adjacent partitions 23 gradually decreases along the conveying direction of the feeding conveyor 2, thereby reducing the lid spacing between each conveying channel 231 at the unloading conveying position 22, so that the lids of each conveying channel 231 are close to each other, so that the lids can be subsequently installed into the box. Specifically, the gap between two adjacent partitions 23 can be gradually reduced to the size of the lid opening diameter, but is not limited thereto.

[0030] Please see Figure 6 and Figure 7 In one embodiment, a plurality of positioning sensors 241 corresponding one-to-one with the conveying channels 231 are provided above the baffle 24. The positioning sensors 241 are electrically connected to the flipping transfer robot 5. The positioning sensors 241 are used to detect whether the cover has reached the unloading conveying position 22 and abutted against the baffle 24, so that the flipping transfer robot 5 can subsequently transport the covers in each conveying channel 231 at the position of the unloading conveying position 22.

[0031] Please see Figures 1 to 6In one embodiment, the feeding module 3 includes a picking robot 31 and a loading transfer robot 32. The picking robot 31 and the loading transfer robot 32 are respectively mounted on the frame 1. The picking robot 31 is located on one side of the loading transfer robot 32, and the loading transfer robot 32 is located on one side of the flipping loading robot 4. The picking robot 31 is used to transport the cover to one side of the loading transfer robot 32. The loading transfer robot 32 is used to transport the cover on the picking robot 31 to one side of the flipping loading robot 4 and rotate the cover so that the bottom outer side of the cover faces the flipping loading robot 4, so that the flipping loading robot 4 picks up the bottom outer side of the cover and flips the cover opening downward.

[0032] Specifically, in one embodiment, the material handling robot 31 includes a material handling moving drive mechanism 311 and a material handling suction unit 312. The material handling moving drive mechanism 311 is mounted on the frame 1, and the material handling suction unit 312 is mounted on the material handling moving drive mechanism 311. The material handling moving drive mechanism 311 drives the material handling suction unit 312 to move, and the material handling suction unit 312 is used to pick up several caps in a horizontal direction. The material handling moving drive mechanism 311 can be an existing linear drive module, and the material handling suction unit 312 can be an existing suction cup suction structure.

[0033] More specifically, the loading transfer robot 32 includes a loading transfer frame 321, a loading transfer rotary drive mechanism 322, and a loading transfer suction unit 323. The loading transfer frame 321 is mounted on the frame 1, and the loading transfer rotary drive mechanism 322 is mounted on the loading transfer frame 321. Several loading transfer suction units 323 are rotatably connected to the loading transfer frame 321, and the loading transfer rotary drive mechanism 322 is connected to each loading transfer suction unit 323. The loading transfer suction units 323 are used to pick up the covers on the material picking suction unit 312. The loading transfer rotary drive mechanism 322 drives each loading transfer suction unit 323 to rotate, so that the loading transfer suction unit 323 drives the picked-up covers to rotate, thereby making the bottom outer side of the covers face the flipping loading robot 4. The loading transfer rotary drive mechanism 322 can adopt an existing rotary drive module, and the loading transfer suction unit 323 can adopt an existing suction cup suction structure.

[0034] Furthermore, the lid packing equipment 100 of this utility model also includes an injection molding machine 7, which is located on one side of the material handling robot 31. The injection molding machine 7 is used to injection mold the lids. The material handling robot 31 can move into the injection molding machine 7 and transport the lids inside the injection molding machine 7 to one side of the loading transfer robot 32.

[0035] Since the cap produced by injection molding machine 7 has its opening horizontally facing the mold inside, when the material handling robot 31's material handling drive mechanism 311 drives the material handling suction part 312 to move into injection molding machine 7, the bottom outer side of the cap faces the material handling suction part 312, and the material handling suction part 312 picks up the bottom outer side of the cap. Therefore, when the material handling drive mechanism 311 drives the material handling suction part 312 to move out of injection molding machine 7 and move to the side of loading transfer robot 32, the cap opening faces the loading transfer robot 32. Therefore, when the loading transfer suction part 323 of loading transfer robot 32 picks up the cap from the material handling suction part 312 of material handling robot 31, the loading transfer... The suction unit 323 penetrates into the lid and adsorbs the inner bottom of the lid. After the suction unit 323 picks up the lid, the loading transfer rotary drive mechanism 322 drives each loading transfer suction unit 323 to rotate, so that the suction unit 323 drives the lid to rotate, thereby making the outer bottom of the lid face the flipping loading robot 4. This facilitates the flipping loading robot 4's suction unit 42 to pick up the outer bottom of the lid. When the flipping loading robot 4's loading drive mechanism 41 drives the flipping loading suction unit 42 to flip together with the lid, the lid opening can be flipped downwards and placed in each conveying channel 231 of the loading conveying position 21. Placing the lid opening downwards in each conveying channel 231 can prevent the loading conveying mechanism 2 from tipping over due to mutual pushing when conveying the lid, especially for some conical lids.

[0036] Please see Figure 2 and Figure 8In one embodiment, the flipping transfer robot 5 includes a flipping drive mechanism 51, a retracting movement drive mechanism 52, and a flipping transfer suction unit 53. The flipping drive mechanism 51 is mounted on the frame 1, the retracting movement drive mechanism 52 is mounted on the flipping drive mechanism 51, and a plurality of flipping transfer suction units 53 are arranged side by side on the retracting movement drive mechanism 52. The flipping transfer suction units 53 are used to suction a target number of lids in the conveying channel 231. The retracting movement drive mechanism 52 is used to drive each flipping transfer suction unit 53 to move, thereby adjusting the interval between each flipping transfer suction unit 53 and thus adjusting the interval between the suctioned lids. The flipping drive mechanism 51 is used to drive the retracting movement drive mechanism 52 to flip together with the flipping transfer suction units 53, so as to drive the lids to flip to one side of the flipping unloading robot 6. After the flipping transfer suction unit 53 picks up the target number of lids from the conveying channel 231, the flipping drive mechanism 51 drives the retraction movement drive mechanism 52 and the flipping transfer suction unit 53 to flip together with the lids. For example, the flipping angle can be 90 degrees, so that the lid opening faces the flipping unloading robot 6, so that the flipping unloading robot 6 can reach into the inside of the lid and pick up the bottom inner side of the lid. At the same time, during this process, the retraction movement drive mechanism 52 is used to drive each flipping transfer suction unit 53 to move, thereby adjusting the interval between each flipping transfer suction unit 53, and thus adjusting the interval between the picked-up lids, so that the lids are tightly attached to each other. This ensures that there are no gaps between the lids in each array and between the lids and the inner wall of the box when the lids are subsequently loaded into the box, and at the same time, it ensures that the lids of the production batch match the box specifications. The flipping drive mechanism 51 and the retraction movement drive mechanism 52 can use existing drive modules, and the flipping transfer suction unit 53 can use existing suction cup suction structure.

[0037] Please see Figure 2 and Figure 9In one embodiment, the flipping and unloading robot 6 includes an unloading movement drive mechanism 61, a flipping and unloading drive mechanism 62, and a flipping and unloading suction part 63. The unloading movement drive mechanism 61 is mounted on the frame 1, the flipping and unloading drive mechanism 62 is mounted on the unloading movement drive mechanism 61, and the flipping and unloading suction part 63 is mounted on the flipping and unloading drive mechanism 62. The unloading movement drive mechanism 61 drives the flipping and unloading drive mechanism 62 and the flipping and unloading suction part 63 to move together, so that the flipping and unloading suction part 63 picks up the inner bottom of the cover on the flipping and transferring suction part 53 of the flipping and transferring robot 5. The flipping and unloading drive mechanism 62 drives the flipping and unloading suction part 63 to flip, so that the bottom of the cover faces down and the opening faces up. The unloading movement drive mechanism 61 drives the flipping and unloading drive mechanism 62 and the flipping and unloading suction part 63 to move down, so that the flipping and unloading suction part 63 moves to the position corresponding to the box and stacks the covers in the box in sequence. The unloading moving drive mechanism 61 and the flipping unloading drive mechanism 62 can adopt existing drive modules, and the flipping unloading suction part 63 can adopt existing suction cup suction structure.

[0038] Please see Figure 2 and Figure 10 In one embodiment, the lid packing device 100 of this utility model further includes an empty box conveying mechanism 8, an empty box pushing mechanism 81, a box positioning mechanism 82, a box unloading and pushing mechanism 83, and a box unloading and conveying mechanism 84, which are respectively disposed on the frame 1. The empty box conveying mechanism 8 is used to convey empty boxes. The empty box pushing mechanism 81 is disposed between the empty box conveying mechanism 8 and the box positioning mechanism 82. The empty box pushing mechanism 81 is used to push the boxes on the empty box conveying mechanism 8 to the box positioning mechanism 82. The box positioning mechanism 82 is used to position the boxes. The flipping unloading robot 6 can stack the lids layer by layer in the boxes. The box unloading and pushing mechanism 83 is disposed between the box positioning mechanism 82 and the box unloading and conveying mechanism 84. The box unloading and pushing mechanism 83 is used to push the boxes with lids on the box positioning mechanism 82 to the box unloading and conveying mechanism 84. The box unloading and conveying mechanism 84 is used to transport the boxes for unloading. The empty box push mechanism 81 pushes the boxes from the empty box conveyor 8 to the box positioning mechanism 82. The box positioning mechanism 82 positions the boxes so that the flipping and unloading robot 6 can stack the lids into the boxes one by one. After the box is full of lids, the box positioning mechanism 82 releases the boxes. The box unloading push mechanism 83 pushes the boxes with lids from the box positioning mechanism 82 to the box unloading conveyor 84. The box unloading conveyor 84 transports the boxes to move and unload them.

[0039] Please see Figure 2In one embodiment, the lid packing equipment 100 of this utility model further includes a lid unloading conveying mechanism 9. The lid unloading conveying mechanism 9 is mounted on the frame 1. The flipping unloading robot 6 can transport the lids to the lid unloading conveying mechanism 9, allowing the lid unloading conveying mechanism 9 to transport the lids for unloading. When the lids do not need to be packed but need to flow to other processes, the flipping unloading robot 6 can transport the lids to the lid unloading conveying mechanism 9, allowing the lid unloading conveying mechanism 9 to transport the lids for unloading. Specifically, the lid unloading conveying mechanism 9 is movably and adjustablely mounted on the frame 1. When the lids do not need to be packed but need to flow to other processes, the lid unloading conveying mechanism 9 can be moved above the box positioning mechanism 82, allowing the flipping unloading robot 6 to quickly place the lids on the lid unloading conveying mechanism 9. When the lids need to be packed, the lid unloading conveying mechanism 9 can be moved away from above the box positioning mechanism 82, allowing the flipping unloading robot 6 to quickly load the lids into the boxes.

[0040] Combination Figures 1 to 10 The specific working principle of the lid packing device 100 of this utility model is as follows:

[0041] The material handling moving drive mechanism 311 of the material handling robot 31 drives the material handling suction unit 312 to move into the injection molding machine 7. The material handling suction unit 312 picks up the bottom outer side of the cover. The material handling moving drive mechanism 311 then drives the material handling suction unit 312 to move out of the injection molding machine 7 and move to the side of the loading transfer robot 32. The loading transfer suction unit 323 of the loading transfer robot 32 picks up the cover on the material handling suction unit 312 of the material handling robot 31. Then, the loading transfer rotation drive mechanism 322 drives each loading transfer suction unit 323 to rotate, so that the loading transfer suction unit 323 drives the lid to rotate, so that the bottom outer side of the cover faces the flipping loading robot 4. Then, the flipping loading suction unit 42 of the flipping loading robot 4 picks up the bottom outer side of the cover. The flipping loading drive mechanism 41 of the flipping loading robot 4 drives the flipping loading suction unit 42 to flip together with the cover so that the cover opening flips downward and is placed in each conveying channel 231 of the loading conveying position 21. The feeding conveyor 2 transports the covers in each conveying channel 231 from the feeding conveyor position 21 to the unloading conveyor position 22. After the flipping transfer manipulator 5's flipping transfer suction part 53 picks up the target number of covers in each conveying channel 231, the flipping drive mechanism 51 drives the retraction movement drive mechanism 52 and the flipping transfer suction part 53 to flip together with the covers, so that the opening of the cover faces the flipping unloading manipulator 6, so that the flipping unloading manipulator 6 can extend into the inside of the cover and pick up the bottom inner side of the cover. At the same time, during this process, the retraction movement drive mechanism 52 is used to drive each flipping transfer suction part 53 to move, so as to adjust the interval between each flipping transfer suction part 53, thereby adjusting the interval between the picked-up covers, so that the covers are tightly attached to each other. The feeding and moving drive mechanism 61 drives the flipping feeding drive mechanism 62 together with the flipping feeding suction part 63 to move together, so that the flipping feeding suction part 63 picks up the inner bottom of the cover on the flipping transfer suction part 53 of the flipping transfer robot 5. The flipping feeding drive mechanism 62 drives the flipping feeding suction part 63 to flip, so that the bottom of the cover faces down and the opening faces up. The feeding and moving drive mechanism 61 drives the flipping feeding drive mechanism 62 together with the flipping feeding suction part 63 to move together, so that the flipping feeding suction part 63 moves to the position corresponding to the box and stacks the covers in the box one by one.

[0042] In summary, the lid packing equipment 100 of this utility model achieves precise lid positioning by linking the conveyor channel 231 divided by the partition 23 with the flipping transfer robot 5, and by cooperating with the baffle 24 and the conveyor channel 231. This ensures that the lids being packed accurately match the standard box specifications, such as an 8×8 array (64 pieces / layer), increasing the existing packing density from 75% to 100%, completely eliminating transport gaps, reducing 25% of ineffective space loss, and thus matching the lids of the production batch with the packing specifications. The improved space utilization directly reduces the frequency of transportation, the filler-free design reduces packaging material costs, and the manual handling process is avoided, saving secondary operation costs. The equipment compatibility design can adapt to different box specifications. Secondly, the lid packing equipment 100 of this invention uses a flipping loading robot 4 to flip the lids so that their openings face downwards and place them in the conveying channels 231 of the loading conveyor 21. This ensures that the loading conveyor 2 transports lids with their openings facing downwards, guaranteeing the stability of the lid transport. When the lids are transported to the unloading conveyor 22, they are arranged closely together in each conveying channel 231 under the action of the baffles 24, which helps to reduce the gaps between the lids during subsequent unloading and facilitates subsequent boxing. Furthermore, by flipping the lids using a flipping transfer robot 5, the flipping unloading robot 6 can pick up the lids from the flipping transfer robot 5 and flip the lids so that their openings face upwards. This helps to stack and pack the lids with their openings facing upwards, thus protecting the lids in the box. At the same time, precise control of the lid opening direction ensures stacking stability.
