Description

Technical Field

[0001] The invention belongs to the technical field of plate stacking machines, in particular to a device for continuous automatic stacking of card strips. Background Art

[0002] Pallet strips are a type of cardboard used to separate and position products. During pallet strip processing, several pallet strips are cut into uniform sizes on a production line and then palletized using palletizing equipment, allowing them to be stacked together for packaging and transport.

[0003] During pallet processing, the pallet strips undergo a cutting process, which cuts the strips into the required specifications, facilitating uniform palletizing. Existing palletizing equipment palletizes the strips by transporting them in a single layer to a stacker station, where the stacker's clamping mechanism grips the strips. The next layer of products then enters the stacker, and the clamping mechanism releases, allowing the gripped products to fall onto the stacker's products. This process continues until the desired height is reached.

[0004] Because burrs remain during cutting, and most cutting equipment struggles to remove them promptly, a significant amount of burrs remain around the edges of the pallet strips. These remaining burrs can cause uneven edges, leading to loose contact between layers when stacked, potentially creating gaps or misalignments. This in turn reduces the overall stability of the pallet, causing it to tilt or collapse during handling or transportation, resulting in damage to the cargo or accidents. Furthermore, after palletizing, the pallet strips are wrapped and secured with film. However, the remaining burrs around the strips can easily puncture the film, making it difficult to effectively restrain the strips. This can also cause the stacked strips to topple over during bumpy transport.

[0005] To this end, the present invention provides a continuous automatic palletizing device for pallet strips. Summary of the Invention

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention relates to a continuous automatic palletizing device for pallet strips. After a palletizer completes palletizing, the palletized strips are placed on a conveyor belt awaiting transport. An air pump then pumps air through several air ducts into several connecting arms, thereby moving several extension arms within the connecting arms. These extension arms, along with the fixing plates and cutting blades, move to appropriate positions, facilitating the adaptation of pallet strips of varying sizes and improving the adaptability of the device. The electric push rod on the fixed frame is then activated. The electric push rod, through its output end, moves the fixing column, connecting arms, extension arms, fixing plates, and cutting blades toward the pallet strips. The end of the cutting blade removes burrs from the edges of the pallet strips. This designed structure allows for rapid and neat palletizing of the pallet strips, while the designed cutting mechanism simultaneously deburrs the palletized strips. Deburring effectively prevents uneven edges on the pallet strips, which can lead to loose contact between layers when stacking, potentially causing gaps or misalignment and reducing overall pallet stability. Deburring also prevents burrs from puncturing the film when wrapping the strips, reducing its restraint and causing it to collapse.

[0019] 2. The present invention describes a device for continuous automatic stacking of card strips. When the electric push rod moves the fixed column downward, it will move the sliding column downward together through the fixed column, so that the fixed plate, several rectangular plates and several gaskets at the bottom of the sliding column move downward together. The fixed plate, rectangular plates and gaskets are used to press and position the card strip body after stacking, so that the card strip body will not be displaced during subsequent cutting. By designing several rectangular plates and gaskets, the volume of the fixed plate can be reduced, thereby achieving lightweight while enabling efficient extrusion. The gasket is designed to be made of a flexible material so as not to damage the card strip body during extrusion. Since the fixed column and the sliding column are slidably connected, after the fixed plate at the bottom of the sliding column has abutted against the card strip body, the electric push rod can still continue to drive the fixed column to slide downward, thereby facilitating the cutting knife to perform cutting operations on the four sides of the card strip body.

[0020] 3. The present invention discloses a continuous automatic palletizing device for pallet strips. The connecting arm moves upward to squeeze several elastic blocks, achieving efficient compression of the blocks. This effectively forces the compressed air within the blocks into the corresponding fixed cylinders through corresponding connecting tubes. The compressed air pushes a sliding cylinder within the fixed cylinder, causing it to move toward the cutting blade, carrying the cleaning plate and brush. Once cleaning is complete, the elastic blocks are no longer squeezed. The air within the fixed cylinder then flows back into the elastic blocks through the connecting tubes, and the sliding cylinder, carrying the cleaning plate and brush, returns to its original position. The returned brush continuously contacts an inverted U-shaped connecting rod, which continuously swings the brush, removing impurities removed by the brush and facilitating efficient operation. After extended use, the cutting blade requires maintenance. The bottom of the fixed column squeezes several rubber cartridges on the top of the fixed plate, causing the pre-stored maintenance fluid within the cartridges to be sprayed onto the brush through the liquid guide tubes. When the brush subsequently removes impurities from the cutting knife, it will use the maintenance fluid on the surface to maintain the cutting knife, thereby extending the service life of the cutting knife.

[0021] 4. In the present invention, a device for continuous automatic palletizing of pallet strips is described. When the fixed column slides downward toward the sliding column, it squeezes several elastic members inside, causing the gas in the elastic members to be discharged through the shrinkage hole into the storage groove of the fixed cone. The gas in the storage groove is then discharged into the clamping plate through the connecting pipe and blown onto the conveyor belt of the palletizer through the air outlet of the clamping plate, blowing out impurities generated after cutting on the conveyor belt through the through-slot. After the gas in the elastic members is squeezed out, when it is no longer squeezed by the fixed column, it is replenished through the pipeline, making it convenient for the next use. When all the pallet strip bodies on the palletizer are transferred to the next process, there are no pallet strip bodies on the palletizer. The electric push rod is started again and the above steps are repeated. At this time, since there is no obstruction by the pallet strip bodies, the gas blown out of the air outlet can fully clean the palletizer, thereby reducing the amount of impurities remaining on the palletizer that affect the smoothness of the subsequent palletizing of the pallet strip bodies.

[0042] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0043] like Figures 1 to 10 As shown, a continuous automatic palletizing device for card strips according to an embodiment of the present invention includes a palletizer 1, and brackets 2 that are longitudinally movable by cylinders are installed on both sides of the palletizer 1. The sides of the two brackets 2 that are close to each other are connected to a laterally movable clamping plate 3 by a cylinder. A card strip body 4 is provided on the palletizer 1, and two symmetrically arranged transverse plates 5 are fixedly installed on the sides of the two brackets 2 that are close to each other. A positioning plate 6 is connected to the transverse plate 5 by a cylinder; a cutting mechanism 10 is provided on the palletizer 1, and the cutting mechanism 10 includes a fixing frame 11 fixedly connected to the palletizer 1, and the fixing frame 11 has a An electric push rod 12 is fixedly installed on the top, and a fixed column 13 is fixedly installed on the output end of the electric push rod 12. Several connecting arms 14 are fixedly installed on the surface of the fixed column 13. An extension arm 15 is sealed and slidably connected inside the connecting arm 14. A fixing plate 16 is fixedly installed on one end of the extension arm 15, and a cutting knife 17 is fixedly installed on the bottom of the fixing plate 16; an air pump 18 is fixedly installed on the top of the fixed frame 11, and several air guide tubes 19 are fixedly installed on one end of the air pump 18, and the ends of several air guide tubes 19 away from the air pump 18 are respectively connected to the interior of several fixed columns 13.

[0044] Specifically, a grinding mechanism 20 is provided inside the cutting blade 17 . The grinding mechanism 20 includes a grinding plate 21 installed inside the cutting blade 17 via a spring 22 . The grinding plate 21 and the cutting blade 17 are slidably connected.

[0045] During operation, the pallet strip body 4 (i.e., thin sheet) is transported to the palletizer 1 via a conveyor belt. At this point, two clamping plates 3 and two positioning plates 6, driven by several pneumatic cylinders, move toward the pallet strip body 4 and clamp it. Clamping the pallet strip body 4 on all four sides increases stability and prevents it from falling during the ascent and descent process. The bracket 2, driven by the pneumatic cylinders, then moves the clamping plates 3, positioning plates 6, and pallet strip body 4 upward, creating a gap between the pallet strip body 4 and the surface of the palletizer 1, allowing the next pallet strip body 4 to flow onto the palletizer 1. The clamped pallet strip body 4 is then released, allowing it to fall onto the palletizer 1. The fixed frame 11 then moves the clamping plates 3 and positioning plates 6 downward to reset itself, facilitating the repetitive operation. This allows several pallet strip bodies 4 to be stacked to the desired height, completing the palletizing operation. After the palletizing operation is completed, the conveyor belt on the palletizer 1 is started to transport the plurality of card strip bodies 4 to the next process for flipping operation. After the flipping operation is completed, the final film packaging is carried out.

[0046] After the palletizer 1 completes the palletizing of the plurality of pallet strip bodies 4, the palletized pallet strip bodies 4 are placed on a conveyor belt awaiting transport. At this point, an air pump 18 is first used to deliver gas through a plurality of air ducts 19 into the plurality of connecting arms 14, thereby pushing the plurality of extension arms 15 within the plurality of connecting arms 14 to move, causing the extension arms 15 to carry the fixing plate 16 and the cutting blade 17 to the appropriate position (i.e., the cutting blade 17 is aligned with the side of the pallet strip body 4 and can be positioned using a position sensor), thereby facilitating the adaptation of pallet strip bodies 4 of different sizes and improving the adaptability of the device during use. The electric push rod 12 on the fixed frame 11 is then activated, and the electric push rod 12, through the output end, carries the fixing column 13, the connecting arm 14, the extension arm 15, the fixing plate 16, and the cutting blade 17 together toward the pallet strip body 4. The end of the cutting knife 17 is used to cut and remove the burrs around the card strip body 4. As the cutting knife 17 contacts the periphery of the card strip body 4, the grinding plate 21 inside it (sandpaper can be installed on the side close to the card strip body 4) is in continuous contact with the card strip body 4 for fine grinding to further remove the burrs around the card strip body 4.

[0047] The above-described structure enables rapid and neat stacking of the card strip bodies 4. The designed cutting mechanism 10 also deburrs the stacked card strip bodies 4. Deburring effectively prevents uneven edges of the card strip bodies 4, which can lead to loose contact between layers during stacking and potentially cause gaps or misalignment, thereby reducing overall stacking stability. Deburring also prevents burrs from puncturing the film when it is subsequently wrapped around the card strip bodies 4, potentially reducing its restraining force and causing it to collapse.

[0048] A positioning mechanism 30 is provided within the fixed column 13. The positioning mechanism 30 includes a receiving slot 31 defined within the fixed column 13. A sliding column 33 is slidably connected to the interior of the receiving slot 31 via a plurality of elastic members 32. A fixed plate 34 is fixedly mounted to the bottom of the sliding column 33. A plurality of rectangular plates 35 are fixedly mounted on the surface of the fixed plate 34. A gasket 36 made of a flexible material is fixedly mounted to the bottom of each rectangular plate 35.

[0049] During operation, when the electric push rod 12 moves downward with the fixed column 13, it also moves downward with the sliding column 33 through the fixed column 13, causing the fixed plate 34, several rectangular plates 35, and several gaskets 36 at the bottom of the sliding column 33 to move downward together. The fixed plate 34, rectangular plates 35, and gaskets 36 are used to press and position the stacked card strip body 4, preventing displacement of the card strip body 4 during subsequent cutting. The design of several rectangular plates 35 and gaskets 36 can reduce the volume of the fixed plate 34, achieving lightweight and efficient extrusion. The gaskets 36 are designed to be flexible to prevent damage to the card strip body 4 during extrusion. Since the fixed column 13 and the sliding column 33 are slidably connected, when the fixed plate 34 at the bottom of the sliding column 33 has abutted against the card strip body 4, the electric push rod 12 can still continue to drive the fixed column 13 to slide downward (at this time, the fixed column 13 will squeeze the elastic member 32 inside, and the elastic member 32 will keep the sliding column 33 inside the fixed column 13 when it is not squeezed by the fixed column 13), thereby facilitating the cutting knife 17 to cut around the card strip body 4.

[0050] The fixing frame 11 is provided with a cleaning mechanism 40, which includes several hollow elastic blocks 41 fixedly mounted on the fixing frame 11, and a connecting pipe 47 connected to the interior is fixedly mounted on one side of the elastic block 41; four welding frames 42 are fixedly mounted on the fixing frame 11, and two fixed cylinders 43 are fixedly mounted on one side of the welding frame 42, and the two fixed cylinders 43 are arranged in a vertical state, and a sliding cylinder 44 is sealed and slidably connected in the fixed cylinder 43, and a "V"-shaped cleaning plate 45 is fixedly mounted on one end of the sliding cylinder 44, and a brush 46 is installed on the inner wall of the cleaning plate 45; the end of the connecting pipe 47 away from the elastic block 41 is connected to the interior of the fixed cylinder 43.

[0051] Specifically, the connecting arm 14 is provided with an extrusion assembly 48, which includes an extrusion plate 481 fixedly connected to the connecting arm 14. Two symmetrically arranged, arc-shaped auxiliary plates 482 are fixedly mounted on the top of the extrusion plate 481. The fixed disk 34 is provided with a maintenance assembly 49, which includes several hollow rubber boxes 491 fixedly mounted on the fixed disk 34. A liquid guide tube 492 is fixedly mounted on one side of the rubber box 491. The end of the liquid guide tube 492, away from the rubber box 491, is connected to the cleaning plate 45. An inverted U-shaped connecting rod 50 is fixedly mounted on the surface of the fixed cylinder 43, and the connecting rod 50 passes through the brush 46.

[0052] During operation, after deburring the card strip body 4, the electric push rod 12 moves upward and resets, carrying the connecting arm 14, extension arm 15, and cutting blade 17, etc., through the fixed column 13. As the connecting arm 14 moves upward, it brings the extrusion plate 481 and two arc-shaped auxiliary plates 482 to squeeze the multiple elastic blocks 41, effectively squeezing the elastic blocks 41 and forcing the gas within the multiple elastic blocks 41 to enter the corresponding fixed cylinder 43 through the corresponding connecting tube 47. The gas pushes the sliding cylinder 44 within the fixed cylinder 43, causing the sliding cylinder 44 to move toward the cutting blade 17, carrying the cleaning plate 45 and brush 46. The V-shaped cleaning plate 45 and brush 46 work together to clean the remaining plate material on the cutting blade 17, thereby ensuring the sharpness of the end of the cutting blade 17.

[0053] When cleaning is completed, the electric push rod 12 moves downward with the connecting arm 14, and no longer squeezes the elastic block 41. At this time, the gas in the fixed cylinder 43 will flow back to the elastic block 41 through the connecting pipe 47, and the sliding cylinder 44 will follow the reset with the cleaning plate 45 and the brush 46. The reset brush 46 will continue to contact the inverted "U"-shaped connecting rod 50, and the connecting rod 50 will be used to continuously swing the brush 46, so as to remove the impurities swept out by the brush 46, which facilitates the efficient work of the brush 46.

[0054] After prolonged use, the cutting blade 17 requires maintenance. Therefore, as the electric push rod 12 moves downward with the fixed column 13, sliding column 33, and fixed disk 34 to position the card strip body 4, the electric push rod 12 will continue to move the fixed column 13 toward the fixed disk 34. At this time, the bottom of the fixed column 13 will move toward the fixed disk 34, using the bottom of the fixed column 13 to squeeze the several rubber boxes 491 on the top of the fixed disk 34, so that the maintenance liquid pre-stored in the rubber boxes 491 is sprayed onto the brush 46 through the liquid guide tube 492. Subsequently, when the brush 46 removes impurities from the cutting blade 17, it will use the maintenance liquid on its surface to maintain the cutting blade 17, thereby extending the service life of the cutting blade 17.

[0055] The fixed column 13 is provided with a blow-off mechanism 60. The blow-off mechanism 60 includes a connecting pipe 61 connected to the interior of the storage slot 31 and equipped with a one-way valve. The end of the connecting pipe 61 away from the storage slot 31 is connected to the palletizer 1, and a through slot 62 is provided on one side of the palletizer 1. The elastic member 32 is a hollow elastic ball with a shrinkage hole on its surface. The sliding column 33 is sealed and slidingly connected to the fixed column 13. A pipe connected to the interior and equipped with a one-way valve is fixedly mounted on one side of the fixed column 13. A hollow clamping plate 63 is clamped to one side of the palletizer 1. The side of the clamping plate 63 near the clamping strip body 4 has several air outlets 64 connected to the interior. The end of the connecting pipe 61 away from the storage slot 31 is connected to the interior of the clamping plate 63.

[0056] During operation, as the fixed column 13 slides downward toward the sliding column 33, it squeezes the several elastic members 32 within, causing the gas within the elastic members 32 to be discharged through the shrinkage holes into the receiving groove 31 of the fixed cone. The gas within the receiving groove 31 is then discharged through the connecting pipe 61 into the clamping plate 63, and then blown through the air outlet of the clamping plate 63 onto the conveyor belt of the palletizer 1, blowing out impurities generated by cutting on the conveyor belt through the through-slot 62. After the gas within the elastic members 32 is squeezed out, when it is no longer squeezed by the fixed column 13, it is replenished through the pipe, making it convenient for the next use. When all the card strip bodies 4 on the palletizer 1 are transferred to the next process, the palletizer 1 is free of the card strip bodies 4. The electric push rod 12 is activated again and the above steps are repeated. Now, without the card strip bodies 4 blocking the way, the gas blown out of the air outlet 64 can completely clean the palletizer 1, thereby reducing the amount of impurities remaining on the palletizer 1 that affect the smoothness of the subsequent palletizing of the card strip bodies 4.

[0057] Working principle: The card strip body 4 is transported to the palletizer 1 via a conveyor belt. At this time, the two clamps 3 and two positioning plates 6 will move toward the card strip body 4 under the action of several cylinders and clamp it. Clamping the four sides of the card strip body 4 can increase stability and prevent the card strip body 4 from falling during the rising and falling process. At this time, the bracket 2 will drive the clamps 3, positioning plates 6 and the card strip body 4 to move upward under the action of the cylinder, so that there is a gap between the card strip body 4 and the surface of the palletizer 1, which is convenient for the next card strip body 4 to flow onto the palletizer 1. Then, by loosening the two clamps 3 and the two positioning plates 6, the originally clamped card strip body 4 falls on the card strip body 4 of the palletizer 1. At this time, the fixed frame 11 moves down and resets with the clamps 3 and positioning plates 6, which is convenient for continuing the above-mentioned reciprocating operation, thereby stacking several card strip bodies 4 to the required height and completing the palletizing operation. After the palletizing operation is completed, the conveyor belt on the palletizer 1 is activated, transporting the multiple card strip bodies 4 to the next process for flipping. After the flipping operation is completed, the final film packaging is carried out. When the multiple card strip bodies 4 have completed the palletizing operation on the palletizer 1, the palletized card strip bodies 4 are placed on the conveyor belt awaiting transportation. At this time, the air pump 18 is first used to transport gas through the multiple air ducts 19 into the multiple connecting arms 14, thereby pushing the multiple extension arms 15 within the multiple connecting arms 14 to move, so that the extension arms 15, with the fixed plate 16 and cutting knife 17, move to the appropriate position, thereby facilitating the adaptation of card strip bodies 4 of different sizes and improving the adaptability of the equipment during use. The electric push rod 12 on the fixed frame 11 is then activated. The electric push rod 12, through the output end, carries the fixed column 13, connecting arm 14, extension arm 15, fixed plate 16, and cutting knife 17 together and moves toward the card strip body 4. The end of the cutting knife 17 is used to cut and remove the burrs around the card strip body 4. As the cutting knife 17 contacts the periphery of the card strip body 4, the grinding plate 21 inside it continuously contacts the card strip body 4 for fine grinding to further remove the burrs around the card strip body 4.

[0058] When the electric push rod 12 moves downward with the fixed column 13, it will move downward with the sliding column 33 through the fixed column 13, so that the fixed plate 34, several rectangular plates 35 and several gaskets 36 at the bottom of the sliding column 33 move downward together, and the fixed plate 34, rectangular plates 35 and gaskets 36 are used to press and position the stacked card strip body 4, so that the card strip body 4 will not be displaced during subsequent cutting.

[0059] After deburring the card strip body 4, the electric push rod 12 moves upward and resets via the fixed column 13, carrying the connecting arm 14, extension arm 15, and cutting blade 17. As the connecting arm 14 moves upward, it brings the extrusion plate 481 and two curved auxiliary plates 482 to squeeze the elastic blocks 41, effectively squeezing the elastic blocks 41 and forcing the gas within the elastic blocks 41 to enter the corresponding fixed cylinders 43 through the corresponding connecting tubes 47. The gas pushes the sliding cylinder 44 within the fixed cylinder 43, causing it to move toward the cutting blade 17, carrying the cleaning plate 45 and brush 46. When cleaning is completed, the electric push rod 12 moves downward with the connecting arm 14, and no longer squeezes the elastic block 41. At this time, the gas in the fixed cylinder 43 will flow back into the elastic block 41 through the connecting pipe 47, and the sliding cylinder 44 will follow the reset with the cleaning plate 45 and the brush 46. The reset brush 46 will continuously contact the inverted "U"-shaped connecting rod 50, and the brush 46 will be continuously swung by the connecting rod 50, thereby removing the impurities swept by the brush 46, facilitating the efficient operation of the brush 46. After a long period of use, the cutting knife 17 needs to be maintained. Therefore, when the electric push rod 12 moves downward with the fixed column 13, the sliding column 33 and the fixed plate 34 to position the card strip body 4, the electric push rod 12 will continue to move the fixed column 13 toward the fixed plate 34. At this time, the bottom of the fixed column 13 will move toward the fixed plate 34, and the bottom of the fixed column 13 will be used to squeeze the several rubber boxes 491 on the top of the fixed plate 34, so that the maintenance liquid pre-stored in the rubber box 491 is sprayed onto the brush 46 through the liquid guide tube 492.

[0060] When the fixed column 13 slides downward toward the sliding column 33, it squeezes the several elastic members 32 inside, causing the gas in the elastic member 32 to be discharged into the receiving groove 31 of the fixed cone through the shrinkage hole. The gas in the receiving groove 31 is then discharged into the clamping plate 63 through the connecting pipe 61 and blown onto the conveyor belt of the palletizer 1 through the air outlet of the clamping plate 63, blowing out the impurities generated after cutting on the conveyor belt through the through groove 62. After the gas in the elastic member 32 is squeezed out, when it is no longer squeezed by the fixed column 13, it will be replenished through the pipeline, making it convenient for next use. When all the card strip bodies 4 on the palletizer 1 are transferred to the next process, there are no card strip bodies 4 on the palletizer 1. The electric push rod 12 is started again and the above steps are repeated. At this time, since there is no obstruction by the card strip body 4, the gas blown out of the air outlet 64 can fully clean the palletizer 1.
