[0002] Cardboard boxes are commonly used as wrapping materials for goods or as protective outer layers for items. As an indispensable part of modern logistics, they bear the important responsibility of containing, protecting, and presenting products aesthetically. After the items are packaged in cardboard boxes, they need to be picked up and stacked by a palletizer.
[0003] Traditional suction cup palletizers often experience problems when using cartons. Dust on the surface of the cartons affects the suction effect of the vacuum cups, causing cartons to easily detach from the suction cups and fall during palletizing, thus reducing palletizing efficiency. Therefore, a new technical solution is needed to address this issue. Summary of the Invention
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a cardboard box unloading palletizer fixture to solve the technical problem that when using current suction cup palletizers, dust on the surface of the cardboard box affects the suction effect of the vacuum suction cup on the cardboard box, causing the cardboard box to easily detach from the vacuum suction cup and fall off during palletizing, thus affecting the efficiency of cardboard box palletizing.
[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A palletizing machine fixture for discharging cartons is designed, comprising:
[0006] Clamping assembly for gripping and stacking cartons;
[0007] The cleaning assembly includes a fixed frame disposed on the outside of the connecting plate. The fixed frame is a horizontally placed U-shaped frame. A support rod is fixedly connected between one side of the fixed frame and one end of the connecting plate. Slide grooves are provided on both sides of the inner cavity of the fixed frame. A slider is slidably connected in each of the two slide grooves. A connecting shaft is rotatably connected between the two sliders through a bearing. A brush roller is fixedly connected to the outside of the connecting shaft.
[0008] A horizontal drive assembly is disposed inside the fixed frame and is used to drive the brush roller to reciprocate along the horizontal direction of the fixed frame.
[0009] Preferably, the horizontal drive assembly includes a lead screw rotatably connected to both sides of one of the inner cavities of the slide groove via bearings, the slider being threaded onto the outside of the lead screw, a drive motor being fixedly mounted at one end of the fixed frame, and the drive end of the drive motor rotatably passing through the fixed frame and connected to the lead screw via a coupling.
[0010] Preferably, the clamping assembly includes a plurality of vacuum suction cups fixedly installed on the bottom of the connecting plate, a vacuum pump is provided above the connecting plate, and an air pipe connects the vacuum pump and the plurality of vacuum suction cups.
[0011] Preferably, a connecting frame is fixedly connected between the top two sides of the connecting plate, and a flange-type adapter is fixedly connected to the top center of the connecting frame.
[0012] Preferably, a rack is fixedly connected to one end of the outer side of the fixed frame, a first rectangular hole is provided at the end of the fixed frame near the rack, and the first rectangular hole communicates with the slide groove. The end of the connecting shaft near the first rectangular hole rotatably passes through the slider and the first rectangular hole. A gear is fixedly connected to the connecting shaft on the outer side of the fixed frame, and the gear meshes with the rack.
[0013] Preferably, each of the two sliders is fixedly connected to a connecting block at both ends, and an arc-shaped plate is fixedly connected between the two connecting blocks on both sides. The arc-shaped plate has a hollow structure, and a plurality of dust suction holes are opened at the end of the arc-shaped plate near the brush roller. The dust suction holes are connected to the inner cavity of the arc-shaped plate. A second rectangular hole is opened at the end of the fixing frame away from the first rectangular hole. The second rectangular hole is connected to the inner cavity of the slide groove. A vacuum cleaner is fixedly connected to the middle of the end of the fixing frame near the second rectangular hole by a fixing rod.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0024] Example 1: A palletizer for cardboard box unloading, see [link to example]. Figures 1 to 4The system includes: a clamping assembly for clamping and stacking cartons, the clamping assembly including multiple vacuum suction cups 11 fixedly installed at the bottom of a connecting plate 1, a vacuum pump 14 disposed above the connecting plate 1, an air pipe 12 connecting the vacuum pump 14 and the multiple vacuum suction cups 11, a connecting frame 13 fixedly connected between the top two sides of the connecting plate 1, and a flange-type adapter 15 fixedly connected to the top center of the connecting frame 13; and a cleaning assembly including a fixing frame 21 disposed on the outside of the connecting plate 1, the fixing frame 21 being a horizontally placed U-shaped frame, the length and width of the fixing frame 21 being greater than the length and width of the connecting plate 1, a support rod 2 fixedly connected between one side of the surface of the fixing frame 21 and one end of the connecting plate 1, and two... Each side is provided with a sliding groove 3, and a slider 33 is slidably connected in each of the two sliding grooves 3. The two sliders 33 are rotatably connected to a connecting shaft 7 via a bearing. A brush roller 5 is fixedly connected to the outside of the connecting shaft 7. The bristles on the brush roller 5 are nylon brushes. A horizontal drive assembly is set inside the fixed frame 21. The horizontal drive assembly is used to drive the brush roller 5 to reciprocate along the horizontal direction of the fixed frame 21. The horizontal drive assembly includes a lead screw 31 rotatably connected to both sides of the inner cavity of one of the sliding grooves 3 via bearings. The slider 33 is threaded onto the outside of the lead screw 31. A drive motor 32 is fixedly installed at one end of the fixed frame 21. The drive end of the drive motor 32 rotatably passes through the fixed frame 21 and is connected to the lead screw 31 via a coupling.
[0025] In operation, initially, the brush roller 5 is positioned on one side of the connecting plate 1. When the cartons are being suction-stacking and stacked, the brush roller 5 is aligned with the top surface of the cartons. Then, the drive motor 32 is started, driving the lead screw 31 to rotate. This, in turn, coordinates with the slider 33 to guide the brush roller 5 within the groove 3, thus moving the brush roller 5 between the vacuum suction cup 11 and the cartons, from one side of the fixed frame 21 to the other. During this movement, the brush roller 5 contacts the vacuum suction cup 11 and the surface of the cartons, allowing it to clean dust from both surfaces. After the vacuum suction cup 11 is aligned with the top of the cartons, the operation is started. The negative pressure pump generates negative pressure inside the vacuum suction cup 11, thereby using negative pressure to pick up and stack cartons. This prevents dust from affecting the suction force of the vacuum suction cup 11 on the cartons, and further prevents cartons from falling off the vacuum suction cup 11 due to dust when it picks up and stacks them, thus improving the efficiency of carton stacking. When stacking the next carton, the drive motor 32 rotates in the opposite direction (the forward and reverse rotation of the motor is a well-known technology and will not be elaborated on here), thereby moving the brush roller 5 from one side of the fixed frame 21 to the other side. The reciprocating movement of the brush roller 5 can clean the dust from the vacuum suction cup 11 and the surface of the carton.
[0026] For details, see Figure 1 and Figure 4 A rack 41 is fixedly connected to one end of the outer side of the fixed frame 21. A first rectangular hole 4 is provided at the end of the fixed frame 21 near the rack 41, and the first rectangular hole 4 communicates with the slide groove 3. The width of the first rectangular hole 4 is smaller than the width of the slide groove 3. The end of the connecting shaft 7 near the first rectangular hole 4 rotates through the slider 33 and the first rectangular hole 4. A gear 42 is fixedly connected to the connecting shaft 7 on the outer side of the fixed frame 21. The gear 42 meshes with the rack 41. When the brush roller 5 moves horizontally to clean dust from the vacuum suction cup 11 and the surface of the carton, the brush roller 5 can rotate when it moves because the gear 42 meshes with the rack 41, thereby improving the cleaning effect of the brush roller 5 on the vacuum suction cup 11 and the surface of the carton.
[0027] Further, see Figure 2 and Figure 3 Both ends of the two sliders 33 are fixedly connected to connecting blocks 61. An arc-shaped plate 6 is fixedly connected between the two connecting blocks 61 on both sides. The arc-shaped plate 6 has a hollow structure. Multiple dust suction holes are opened at the end of the arc-shaped plate 6 near the brush roller 5, and the dust suction holes are connected to the inner cavity of the arc-shaped plate 6. The height of the arc-shaped plate 6 is less than the diameter of the brush roller 5. A second rectangular hole 64 is opened at the end of the fixing frame 21 away from the first rectangular hole 4, and the second rectangular hole 64 is connected to the inner cavity of the slide groove 3. The width of the second rectangular hole 64 is less than the width of the slide groove 3. A vacuum cleaner 63 is fixedly connected to the middle of the end of the fixing frame 21 near the second rectangular hole 64 by a fixing rod. The vacuum cleaner 63 has... The suction port 66 is connected to a suction hose 62, which passes through the connecting block 61 and communicates with the inner cavity of one of the arc-shaped plates 6. A conduit 65 is fixedly connected between the bottoms of the two arc-shaped plates 6, and the two ends of the conduit 65 are respectively connected to the inner cavities of the two arc-shaped plates 6. When the brush roller 5 moves horizontally to clean the dust on the vacuum suction cup 11 and the surface of the carton, the vacuum cleaner 63 is activated to generate negative pressure at the suction port (how the vacuum cleaner 63 suctions dust is a well-known technology and will not be described in detail here). The dust cleaned by the brush roller 5 is collected in the vacuum cleaner 63 through the suction port, the inner cavity of the arc-shaped plate 6, and the suction hose 62, thereby avoiding secondary pollution of the carton and the vacuum suction cup 11 by the cleaned dust.
[0028] A palletizing machine, wherein a palletizing machine clamp for discharging cartons is rigidly connected to the end effector of the palletizing machine's robotic arm via high-strength bolts. The robotic arm moves along a preset trajectory, driving the clamp assembly to move and palletize the cartons.
