Description

Technical Field

[0001] The present application relates to the technical field of automatic packaging equipment, and in particular to an automatic cardboard packaging equipment. Background Art

[0002] In the papermaking industry, plant fiber raw materials (such as wood, bamboo, reed, grass, cotton, hemp, bagasse, etc.) are usually used to make pulp, while cardboard is a thick paper sheet processed from various pulps, the fibers of which are interwoven with each other. The main difference between cardboard and paper is the basis weight and thickness; cardboard is a high-strength, lightweight, soft, foldable material that can be easily processed into various shapes. It can be used to make various forms of cartons, such as corrugated boxes, folding cartons, gift boxes, etc., which are suitable for packaging and transporting various commodities. Due to its good compression resistance, vibration resistance and protective properties, cardboard packaging performs well in protecting goods.

[0003] In order to facilitate the subsequent storage, transportation and sales of cardboard, it is necessary to pack the cardboard. The packing process first involves stacking several cardboards, and then using strapping tape to bundle them after reaching a certain amount. In order to reduce the damage to the cardboard during the bundling process, it is necessary to cover the outer periphery of the cardboard pile with larger wrapping paper before bundling. This wrapping paper separates the strapping tape from the cardboard pile, thereby forming a protective effect.

[0004] For the wrapping paper, a folding operation is required so that the larger wrapping paper can cover the sides of the cardboard pile downward / upward. In the existing packaging equipment, this step is performed by a folding device, in which a folding board and a cylinder are provided. The folding board is driven by the cylinder to fold the wrapping paper to the side of the cardboard pile for the subsequent bundling process.

[0005] In the actual folding process, if the position of the cardboard pile shifts toward the cylinder, the movement of the cylinder is rigid and there is no buffer space, which causes the origami paper to bend the edge of the cardboard pile during folding, causing damage; in addition, not every cardboard in the cardboard pile can be aligned, and some edges are protruding. When the origami paper with rigid movement is folded, the edges of some cardboards are damaged, thereby affecting the size of the entire cardboard and reducing the integrity.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] The present application provides an automatic cardboard packaging device, which is used to reduce the damage to the cardboard caused by the folding process and improve the integrity of the cardboard. The specific implementation process of the present application is described as follows.

[0040] See also Figures 1 to 8 , the present application provides an automatic cardboard packaging device comprising:

[0041] The transport component 01, the wrapping paper device 02, the longitudinal paper folding device 03, the transverse paper folding device 04 and the bundling device 05; the wrapping paper device 02, the longitudinal paper folding device 03 and the transverse paper folding device 04 are fixed in sequence above the transport component 01 along the moving direction of the cardboard pile 06, the transport component 01 is used to carry and drive the cardboard pile 06 to move, the wrapping paper device 02 is used to place the wrapping paper 07 below and above the cardboard pile 06, the longitudinal paper folding device 03 and the transverse paper folding device 04 are used to fold the longitudinal and transverse edges of the wrapping paper 07 respectively; the bundling device 05 is located above the transport component 01 and is fixed on both sides of the transverse paper folding device 04 respectively, and the bundling device 05 is used to bundle the cardboard pile 06 longitudinally and transversely;

[0042] The horizontal paper folding device 04 includes: a fixed frame 08, a lower paper folding paper board 09, an upper paper folding rod 10, a movable frame 11 and an elastic member 12. A guide rail 13 and a support block 14 are provided on the fixed frame 08. The movable frame 11 is connected to the guide rail 13, and the rear end of the movable frame 11 is connected to the support block 14 through the elastic member 12; the lower paper folding paper board 09 is arranged at the front end of the movable frame 11, and the upper paper folding rod 10 is arranged at the top end of the movable frame 11. When the lower paper folding paper board 09 and the upper paper folding rod 10 fold the edges of the packaging paper 07 respectively, the elastic member 12 is used to absorb the force generated when the movable frame 11 moves toward the support plate.

[0043] During the whole packaging process, the cardboard is placed on the transport component 01 for movement. When it moves to the bottom of the wrapping paper device 02, the wrapping paper device 02 places the wrapping paper 07 below and above the cardboard pile 06 respectively. When the cardboard pile 06 covered with the wrapping paper 07 continues to move to the bottom of the longitudinal paper folding device 03, the longitudinal paper folding device 03 folds the edges of the wrapping paper 07 on both sides of the longitudinal direction. After the longitudinal folding is completed, it moves to the bottom of the bundling device 05. The bundling device 05 bundles the wrapping paper 07 that has been folded longitudinally, so that the wrapping paper 07 and the cardboard pile 06 are bundled together in the longitudinal direction; then it moves to the bottom of the transverse paper folding device 04. The transverse paper folding device 04 folds the transverse edges of the wrapping paper 07. After folding, it is bundled transversely by the bundling device 05, thereby realizing the transverse and longitudinal bundling of the cardboard pile 06.

[0044] As the core moving part of the entire automatic cardboard packaging equipment, the transport component 01 is responsible for carrying and driving the cardboard pile 06 to move along a preset track or path. The transport component 01 can use a motor-driven conveyor belt, roller or chain system to ensure the smooth transmission of the cardboard pile 06 during the packaging process. The transport component 01 has the ability to adjust the speed to ensure the continuity and stability of the bundling process.

[0045] The wrapping paper device 02 is responsible for laying wrapping paper 07 at the bottom and top of the cardboard pile 06 to prepare for the subsequent paper folding operation. When laying the bottom wrapping paper 07, the wrapping paper device 02 lays the wrapping paper 07 on the transport component 01, so that the wrapping paper 07 is automatically laid at the bottom during the movement of the cardboard pile 06. When laying the top wrapping paper 07, the wrapping paper device 02 directly moves the wrapping paper 07 to the top of the cardboard pile 06 and releases it.

[0046] The longitudinal paper folding device 03 is located behind the wrapping paper device 02. The longitudinal paper folding device 03 is responsible for folding the wrapping paper 07 in the longitudinal direction of the cardboard pile 06 to preliminarily fix the wrapping paper 07 and preliminarily form a packaging shape.

[0047] The bundling device 05 is located above the transport component 01 and fixed on both sides of the transverse paper folding device 04, so as to facilitate the bundling operation immediately after the paper folding is completed. In the present application, two bundling devices 05 are provided, one is located between the transverse paper folding device 04 and the longitudinal paper folding device 03, and the other is located behind the transverse paper folding device 04. The bundling device 05 is used to bundle the cardboard pile 06 longitudinally and transversely, so as to closely fit the packaging paper 07 to the cardboard pile 06, and to enhance the stability of the cardboard pile 06 and protect the integrity of the cardboard pile 06 during transportation.

[0048] The transverse paper folding devices 04 are respectively arranged on both sides of the transport component 01, so as to facilitate folding paper on both transverse sides of the cardboard pile 06 at the same time; in the transverse paper folding device 04, a guide rail 13 is arranged on the fixed frame 08, and the movable frame 11 is movably connected to the guide rail 13. The movable frame 11 can be controlled to move on the guide rail 13. The front end of the movable frame 11 is the end close to the cardboard pile 06, and the front end is fixed with the lower folding paper board 09, and the rear end is connected with the support block 14 through the elastic member 12. The movable frame 11 is arranged in an "L" or "⊥" shape, and the upper paper folding rod 10 is fixed on the top of the movable frame 11. The upper paper folding rod 10 is controlled to move to fold the wrapping paper 07 at the upper end of the cardboard pile 06, and the lower folding paper board 09 is controlled to move to fold the wrapping paper 07 at the lower end of the cardboard pile 06.

[0049] In the actual working process, the transverse paper folding device 04 drives the lower folding paper board 09 and the upper folding paper rod 10 to move respectively, and pushes the packaging paper 07 on the paperboard pile 06 to the side of the paperboard pile 06 according to the preset moving path to achieve the folding effect. Since the moving frame 11 can move freely on the guide rail 13, the moving frame 11 moves to the rear end (towards the support block 14) in the process of pushing the packaging paper 07 to fold. In this way, the folding process is not rigid, but has a buffering effect, which can reduce the damage caused by the lower folding paper board 09 and the upper folding paper rod 10 to the side of the paperboard pile 06 during the folding process, and improve the integrity of the paperboard. After the folding of the packaging paper 07 is completed, the upper folding paper rod 10 and the lower folding paper board 09 are controlled to return to their original state. At this time, under the action of the elastic member 12, the moving frame 11 also returns to its original position, which is convenient for folding the next paperboard pile 06. In addition, since the elastic member 12 has elastic force, during the paper folding process, the packaging paper 07 can be folded and the damage to the side of the paperboard can be reduced.

[0050] The elastic member 12 described in this embodiment can be a rubber pad, a spring, a spring washer, or a compression spring or a torsion spring.

[0051] Please continue reading Figure 3-Figure 4 In an optional embodiment, a first cylinder 15 is provided on the movable frame 11, the first end of the lower folding paper board 09 is fixed to the front end of the fixed frame 08, and the second end of the lower folding paper board 09 is movably connected to the first cylinder 15. The first cylinder 15 is used to drive the second end of the lower folding paper board 09 to rotate around the first end, thereby folding the edge of the packaging paper 07.

[0052] The first cylinder 15 is installed on the movable frame 11, and its piston rod is movably connected to the second end of the lower folding paper board 09. The first cylinder 15 can push the second end of the lower folding paper board 09 to produce the expected movement; the main function of the first cylinder 15 is to provide a driving force so that the lower folding paper board 09 can rotate around its first end (i.e., the end fixed to the front end of the fixed frame 08). During the folding process, the piston rod extends forward to push the second end of the lower folding paper board 09 to rotate around the first end, so that the lower folding paper board 09 gradually approaches and contacts the lateral edge of the packaging paper 07. As the lower folding paper board 09 continues to rotate, the lateral edge of the packaging paper 07 is gradually pushed into the space formed between the paperboard pile 06 and the lower folding paper board 09. When the lower folding paper board 09 rotates to a predetermined position, the lateral edge of the packaging paper 07 is completely folded and flattened on the side of the paperboard pile 06. At this time, the folding is completed. After the folding is completed, the first cylinder 15 is reset to fold the packaging paper 07 for the next paperboard pile 06.

[0053] The second end of the lower folding cardboard 09 is fixed on the fixed frame 08, and the first end is connected to the movable frame 11 through the first cylinder 15. When the first cylinder 15 pushes the first end to rotate toward the cardboard pile 06, since the cardboard pile 06 is stationary, the first cylinder 15 will push the movable frame 11 in the opposite direction to move toward the support rod when it extends, thereby squeezing the elastic member 12.

[0054] In an optional embodiment, the upper paper folding rod 10 is composed of a folding arm 16, a cross bar 17, a second cylinder 18 and a third cylinder 19. The cross bar 17 is fixed to the first end of the folding arm 16, the second end of the folding arm 16 is connected to the fixed block on the movable frame 11, the second cylinder 18 is fixed to the top of the movable frame 11 and connected to the second end of the folding arm 16, the first end and the second end of the folding arm 16 are connected through the third cylinder 19, and the third cylinder 19 is used to drive the cross bar 17 to fold the edge of the wrapping paper 07.

[0055] The folding arm 16 is bendable or rotatable to adapt to the angle change during the folding process. The folding arm 16 serves as a bridge between the crossbar 17 and the mobile frame 11. The crossbar 17 is lifted and rotated through the connection points at both ends of the folding arm 16, thereby completing the folding action of the edge of the wrapping paper 07. The third cylinder 19 is used to drive the second end of the folding arm 16 to rotate to get close to the cardboard pile 06, and to carry the crossbar 17 to rotate during the rotation process. The crossbar 17 applies pressure to the edge of the wrapping paper 07 during the rotation process to achieve the folding effect; the folding arm 16 and the mobile frame 11 are movably connected, and the folding arm 16 can rotate on the mobile frame 11. The two ends of the second cylinder 18 are respectively connected to the mobile frame 11 and the folding arm 16. The second cylinder 18 is used to drive the folding arm 16 to rotate so that the folding arm 16 approaches the cardboard pile 06.

[0056] Please continue reading Figure 4In an optional embodiment, corner folding devices 20 are respectively provided on both sides of the mobile frame 11, and the corner folding devices 20 are used to fold the wrapping paper 07 located on the side of the cardboard pile 06; the corner folding device 20 includes a right-angle plate 21, a folding rod 22 and a fourth cylinder 23, one end of the folding rod 22 is movably connected to the side of the mobile frame 11, and the other end is movably connected to the right-angle plate 21, and the fourth cylinder 23 is connected to the mobile frame 11 and the folding rod 22 respectively, and the fourth cylinder 23 is used to drive the folding rod 22 to swing, so as to align the right-angle plate with the corner position of the cardboard pile. In the overall folding sequence, longitudinal folding is performed first, followed by corner folding, and finally transverse folding is performed. The corner folding folds the wrapping paper 07 located at the corner to the transverse sides of the cardboard pile 06, and then the corner folded in front is covered by transverse folding, so that the wrapping paper 07 tightly wraps the top and bottom surfaces of the cardboard pile 06 and the corners corresponding to the two surfaces.

[0057] For example, the four faces around the cardboard pile 06 are face ①, face ②, face ③ and face ④, wherein the two longitudinal faces are face ① and face ③, and the two transverse faces are face ② and face ④. During the folding process, firstly, the edges of the wrapping paper 07 on faces ① and ③ are folded to fit the cardboard pile 06 by the longitudinal folding device 03. Secondly, the wrapping paper 07 at the angle between faces ① and ② and the wrapping paper 07 at the angle between faces ① and ④ are folded to fit face ① by the corner folding device 20. The wrapping paper 07 at the angle between faces ③ and ② and the wrapping paper 07 at the angle between faces ③ and ④ are folded to fit face ③. Finally, the wrapping paper 07 on faces ② and ④ is folded by the transverse folding device 04. The folding process of wrapping paper 07 is as follows: Figure 5 shown.

[0058] Please continue reading Figure 8 In an optional embodiment, the transport assembly 01 is composed of a plurality of drive devices 25, each of which is provided with a pulley 26 and a drive motor 27, the drive motor 27 being connected to the pulley 26, and the drive motor 27 being used to drive the pulley 26 to rotate, thereby moving the cardboard pile 06 above the pulley 26. The transport assembly 01 is a transport line composed of a plurality of drive devices 25, and the cardboard pile 06 moves on the transport line; each drive device 25 can independently drive the pulley 26 to rotate, thereby realizing the function of independently controlling the movement of the cardboard pile 06. The operation of the drive motor 27 is controlled manually or by a control system, and a control program is pre-set in the control system, and the control system controls the operation of the drive motor 27 by running the control program.

[0059] The control system is also electrically connected to the transport component 01, the wrapping paper device 02, the longitudinal paper folding device 03, the transverse paper folding device 04 and the bundling device 05 in the present application, and can send control signals to each device through a preset operating program to enable each device to operate.

[0060] Please continue reading Figure 6 In this optional embodiment, a turntable 28 is provided below the transverse paper folding device 04, and a rotating end 29 is provided on the turntable 28. The end of the turntable 28 passes through the transport component 01 upward, and the turntable 28 is used to control the rotation of the rotating end 29 carrying the cardboard pile 06. Specifically, one or more driving devices 25 are respectively arranged below the wrapping paper device 02, the longitudinal paper folding device 03, the transverse paper folding device 04 and the bundling device 05, and only one driving device 25 is arranged below the transverse paper folding device 04. A turntable 28 is arranged below the driving device 25. A rotating end 29 on the turntable 28 passes through the driving device 25 upward, and the height of the rotating end 29 can be adjusted up and down. When not in operation, the position of the rotating end 29 is lower than the upper surface of the driving device 25. When in operation (the cardboard pile 06 is transported to the top of the driving device 25), the rotating end 29 is controlled to rise and lift up the cardboard pile 06, so that the cardboard pile 06 is in a state of not contacting the driving device 25. At this time, the rotating end 29 rotates 90 degrees to rotate the cardboard pile 06 horizontally. After the rotation is completed, the rotating end 29 descends to restore the original height (the height of the rotating end 29 is lower than the upper surface of the driving device 25) to facilitate the subsequent transverse folding and bundling of the cardboard pile 06.

[0061] In an optional embodiment, the automatic cardboard packaging device provided by the present application further includes a weighing device 30 and a steering device 31. The weighing device 30 is disposed in the first driving device 25 at the front of the transport component 01. The weighing device 30 is used to weigh the weight of the cardboard pile 06. The steering device 31 is disposed below the second driving device 25. The steering device 31 is used to control the second driving device 25 to rotate 90 degrees. The weighing device may also be provided with a display screen, through which the weight of the cardboard pile 06 can be intuitively displayed.

[0062] In this transport assembly 01, the starting point is the first drive device 25, followed by the second drive device 25. In order to measure the weight of the cardboard pile 06, a weighing device 30 is arranged below the first drive device 25, and the first drive device 25 is fixed above the weighing device 30. When weighing, the weight of the first drive device 25 is weighed first, and then the weight of the first drive device 25 and the cardboard pile 06 are weighed, and then the weight of the cardboard pile 06 is obtained by subtracting them.

[0063] In actual work, there is a situation of manual packaging. At this time, a manual packaging line is added to the transport component 01. The manual packaging line is aligned horizontally with the second drive device 25, and the manual feeding line is also composed of several drive devices 25. After weighing, the unpackaged cardboard pile 06 is transported to the second drive device 25. At this time, the second drive device 25 is controlled by the steering device 31 and rotates horizontally 90 degrees to transport the cardboard pile 06 to the manual packaging line for manual packaging. On the manual packaging line, the wrapping paper 07 is manually placed above and below the cardboard pile 06 to perform manual paper folding. Therefore, manual packaging can be performed when the subsequent horizontal paper folding device 04, the longitudinal paper folding device 03 and other devices are not started, reducing the noise in the workshop and reducing the safety risks during automatic packaging.

[0064] In an optional embodiment, the automatic cardboard packaging equipment also includes: a packing device 32 and a centering device 33, which are respectively arranged above the transport component 01, the packing device 32 is used to compact the cardboard pile 06 from top to bottom, and the centering device 33 is used to push the cardboard pile 06 to the center position of the transport component 01.

[0065] The packing device 32 and the centering device 33 are located between the longitudinal folding device 03 and the steering device 31. The folded paper sheets are firstly packed, that is, the paper sheet stack 06 is squeezed up and down. The squeezing is achieved by hydraulic drive to reduce the gap between the upper and lower adjacent folded paper sheets, so as to improve the tightness of the paper sheet stack 06 during subsequent bundling.

[0066] The centering device 33 is located between the longitudinal paper folding device 03 and the packing device 32. The centering device 33 is used to align the center of the folded paper board pile 06 with the transport component 01, so that the subsequent wrapping paper device 02 can accurately place the wrapping paper 07 above and below the paper board pile 06; and the centering device 33 can also align each paper board to reduce the situation where the edge of the paper board protrudes from the paper board pile 06, thereby reducing the damage to the paper board caused by the subsequent paper folding process.

[0067] Please continue reading Figure 7 In an optional embodiment, the packaging paper device 02 includes a suction cup frame 34 and a suction cup fixing frame 35. The suction cup frame 34 is fixed above the transport component 01. The suction cup fixing frame 35 is movably connected to the suction cup frame 34. The suction cup fixing frame 35 can move on the suction cup frame 34. A plurality of suction cups 36 are arranged on the suction cup fixing frame 35, and the suction cups 36 are used to absorb the packaging paper 07.

[0068] Next to the wrapping paper device 02, a number of wrapping papers 07 are stacked at a position close to the transport component 01. The suction cup fixing frame 35 can move back and forth between this position and the cardboard pile 06. The movement of the suction cup fixing frame 35 can be achieved through the cooperation of a ball screw and a motor, and can also be achieved through a cylinder or an actuator. The suction cup fixing frame 35 can move not only in the horizontal direction, but also in the vertical direction. In the vertical direction, a telescopic rod can be set on the suction cup fixing frame 35 to achieve this. During specific use, the lower wrapping paper 07 is placed first, and the suction cup fixing frame 35 is controlled to move to the position where the wrapping paper 07 is placed, and the suction cup 36 on one side is controlled to absorb a piece of wrapping paper 07, and one side of the wrapping paper 07 is placed on the driving device 25 below the longitudinal packing device, and the other side naturally hangs to the ground, and then the upper wrapping paper 07 is operated again to cover the top of the cardboard pile 06, and the cardboard pile 06 is driven to move toward the longitudinal paper folding device 03. During the movement, the bottom surface of the paper folding pile contacts the lower wrapping paper 07. Under the action of friction, the lower wrapping paper 07 moves together with the cardboard pile 06. When the cardboard pile 06 is completely moved to the bottom of the longitudinal paper folding device 03, the cardboard pile 06 is completely above the lower wrapping paper 07.

[0069] In an optional embodiment, a palletizing device 37 is provided at the end of the transport component 01 . The palletizing device 37 is fixed above the transport component 01 . The palletizing component is used to stack the packaged cardboard piles 06 up and down.

[0070] For the cardboard pile 06 that is bundled both longitudinally and transversely, it is moved away and stacked at a specific position by a transportation device such as a forklift. In order to improve the transportation efficiency, the bundled cardboard pile 06 is stacked, and 2-3 cardboard piles 06 are stacked up and down to facilitate one-time transportation, improve transportation efficiency, and reduce the number of round trips of the transportation device. Based on this, a stacking device 37 is set above the transportation component 01, and the stacking device 37 is behind the transversely bundled bundling device 05. During the stacking process, the first cardboard pile 06 is first grabbed upwards, and when the second cardboard pile 06 moves to the bottom of the stacking device 37, the first cardboard pile 06 is placed above the second cardboard pile 06, and then the first cardboard pile 06 and the second cardboard pile 06 are grabbed upwards together, and when the third cardboard pile 06 moves to the bottom of the stacking device 37, the first cardboard pile 06 and the second cardboard pile 06 are placed downwards on the third cardboard pile 06, thereby achieving palletizing. After palletizing is completed, it is moved to a subsequent position through the transportation component 01 to facilitate the removal of the transportation device.

[0071] In the present application, the overall bundling process is as follows: first, the cardboard pile 06 is weighed by the weighing device 30 to record the weight of the cardboard pile 06 and facilitate subsequent sales; then, the cardboard pile 06 is compacted up and down by the packing device 32 to improve the tightness between the cardboards and reduce the space occupied by the cardboard pile 06; then, the cardboard pile 06 is centered by the centering device 33 and aligned with the center of the transport component 01 to facilitate the accurate placement of the subsequent wrapping paper 07 and reduce the deviation of the subsequent bundling process; then, the upper wrapping paper 07 and the lower wrapping paper 07 are placed by the wrapping paper device 02; then, the edges of the wrapping paper 07 on both sides of the cardboard pile 06 are folded by the longitudinal paper folding device 03. Folding, folding to fit the side of the cardboard pile 06, and then longitudinally bundling through the bundling device 05 to ensure that the wrapping paper 07 is fixed on the outside of the cardboard pile 06 in the longitudinal direction, then the cardboard pile 06 arrives at the bottom of the transverse paper folding device 04, and the cardboard pile 06 is controlled to rotate by the turntable 28 under the transverse paper folding device 04. After the rotation, the transverse paper folding device 04 cooperates with the corner paper folding devices 20 on both sides to fold the transverse edge of the wrapping paper 07 to the transverse side of the cardboard pile 06, and then the bundling device 05 is used to bundling horizontally, thereby completing the bundling process of the cardboard pile 06, and finally the cardboard pile 06 is stacked up and down through the stacking device 37, which is convenient for subsequent transportation by forklifts and other transportation devices.
