Description

Corrugated paper stacking inspection and stratification machine Technical Field

[0001] This invention relates to the field of corrugated paper production technology, specifically to a corrugated paper stack detection and stratification machine. Background Technology

[0002] Corrugated paperboard has a multi-layer structure with an inner core paper supported between two base papers. The core paper is wavy, which results in side holes on one pair of opposite sides of the corrugated paper and a closed opposite pair of sides, meaning that the corrugated paper has a front and back direction.

[0003] The initially processed corrugated cardboard is stacked into square piles. To prevent deformation, the corrugated paper is arranged alternately in opposite directions within the pile. After initial processing, the corrugated paper needs to be quantitatively removed from the pile and transferred to the next process. Therefore, the pile needs to be layered. Currently, the layering method involves manually inserting a pick into the gap between adjacent corrugated paper, then lifting it up, and finally clamping it using a clamping mechanism. This method is inefficient, prone to errors, time-consuming, labor-intensive, and easily damages the corrugated paper. Summary of the Invention

[0004] The purpose of this invention is to provide a corrugated paper stack detection and stratification machine, which aims to solve the technical problem of low stratification efficiency of existing corrugated paper stacks.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0006] The corrugated paper stack inspection and stratification machine includes a frame with a built-in paper stack storage area. Two inspection and stratification mechanisms are installed on the side of the frame. Each inspection and stratification mechanism includes a first translation mechanism, a lifting mechanism installed on the translation end of the first translation mechanism, a second translation mechanism installed on the lifting end of the lifting mechanism, and a visual inspection mechanism facing the paper stack storage area, a pin, and a drive mechanism for driving the pin to extend and retract on the translation end of the second translation mechanism.

[0007] The first translation mechanism includes a multi-stage slide table and a multi-stage scissor linkage mechanism, with adjacent slide tables being slidably connected.

[0008] The multi-stage scissor lift mechanism includes a first link, a second link, a movable shaft, and a fixed shaft. Several first links are arranged in a scissor-like pattern. Two first links that cross in the middle are rotatably connected to the movable shaft, and two first links that cross at the ends are rotatably connected to the movable shaft. Second links are rotatably connected to the movable shaft at both the starting and ending ends of the multi-stage scissor lift mechanism. The outer ends of two second links at the same end are rotatably connected to the fixed shaft. A fixed shaft is fixed to the side of any slide. A locking cap is screwed onto the fixed shaft or the movable shaft.

[0009] The lifting mechanism includes a connecting frame and a lifting platform that is vertically slidably connected to the connecting frame. A conveyor belt is installed on the connecting frame, and the lifting platform is fixed on the conveyor belt.

[0010] The second translation mechanism includes a movable platform slidably connected to the lifting platform and a first motor fixed on the lifting platform. A rack is installed on the movable platform, and a gear that meshes with the rack is coaxially fixed to the motor shaft of the first motor.

[0011] The driving mechanism includes a guide rod slidably connected to the moving platform and a cylinder that drives the guide rod to move. The end of the guide rod facing the paper stacking area is provided with a slot. The inner end of the pin is horizontally hinged in the slot. Elastic elements are connected between the two sides of the pin and the inner wall of the horizontal slot. The elastic elements drive the pin to be coaxial with the guide rod.

[0012] The frame includes a frame body, on which a first limiting frame and a second limiting frame are installed. The limiting surfaces of the first limiting frame and the second limiting frame are perpendicular. There are two second limiting frames, which are symmetrically arranged. The first limiting frame and the two second limiting frames form a paper stacking storage area.

[0013] The first limiting frame includes a first mounting plate that is slidably connected to the frame in the front-to-back direction, and at least two second mounting plates that are slidably connected to the first mounting plate in the left-to-right direction. The second mounting plates are vertically slidably connected to a first limiting rod on the side facing the paper stacking area.

[0014] The second limiting frame includes a sliding frame that is slidably connected to the frame in the front-back direction, and at least two sliding rods that are slidably connected to the sliding frame in the left-right direction. A second limiting rod is fixed to one end of the sliding rod facing the paper stack storage area, and a push-pull rod is fixed between the two sliding rods.

[0015] The sliding rod includes a first rod body and a second rod body that is slidably sleeved within the first rod body. The first rod body is slidably connected to the sliding frame, and the second limiting rod is fixedly connected to the second rod body.

[0016] Among them, a limit plate is fixed to the side of the connecting frame facing the paper stacking area.

[0017] After adopting the above technical solution, the beneficial effects of the present invention are:

[0018] 1. The present invention uses a first translation mechanism to adjust the initial position of the insert pin in the left and right direction of the vertical plane, a lifting mechanism to adjust the position to be layered, and a second translation mechanism to precisely fine-tune the left and right position of the insert pin, so that the insert pin can be accurately inserted into the side hole of the corrugated paper and the paper stack can be lifted up for efficient layering.

[0019] 2. The two detection and layering mechanisms operate independently but can also be used in conjunction. They can lift corrugated paper with a single needle or with both needles simultaneously, improving functionality and adapting to variations in corrugated paper specifications.

[0020] 3. The first translation mechanism adopts a multi-stage sliding table and a multi-stage scissor linkage mechanism, which makes the first translation mechanism more stable when unfolding, has higher support strength, occupies less space when folded up, and can provide sufficient left and right travel range when unfolded.

[0021] 4. Elastic elements are provided on both sides of the horizontal direction of the pin and the guide post, so that the pin can swing horizontally when pressed and reset when not pressed. This ensures that even if the side hole and the pin are not aligned, the pin will not pierce the corrugated paper when it touches the inner wall of the side hole. Instead, it will shift horizontally, preventing the corrugated paper from being pulled off a single layer after the pin is inserted and reset. Attached Figure Description

Detailed Implementation

[0029] The invention will now be further described with reference to the accompanying drawings.

[0030] The orientations mentioned in this specification are based on the orientation of the corrugated paper stacking and stratification machine of this invention during normal operation, and do not limit its orientation during storage and transportation. They only represent relative positional relationships and do not represent absolute positional relationships.

[0031] Example 1

[0032] As shown in Figures 1 to 5, the corrugated paper stack detection and stratification machine includes a frame 1 and two detection and stratification mechanisms. The top view of the frame 1 is U-shaped, that is, one side of the frame of the frame 1 is open and the other three sides are closed. The two detection and stratification mechanisms are respectively installed in the open position of the frame 1.

[0033] The inner side of frame 1 is the paper stacking area, where the corrugated paper processed in the previous process is stacked vertically.

[0034] The detection layering mechanism includes a first translation mechanism 2, a lifting mechanism 3, a second translation mechanism 4, a visual inspection mechanism, a pin 6, and a drive mechanism.

[0035] The lifting mechanism 3 is fixed to the translation end of the first translation mechanism 2, and the first translation mechanism 2 controls the left and right movement of the lifting mechanism 3. The second translation mechanism 4 is fixed to the lifting end of the lifting mechanism 3, and the lifting mechanism 3 controls the up and down movement of the second translation mechanism 4. The vision inspection mechanism is preferably an industrial camera 5, which is electrically connected to the vision inspection system. The industrial camera 5 transmits the acquired image information to the controller of the vision inspection system, and then the controller controls the actions of each mechanism. The industrial camera 5 is fixed to the translation end of the second translation mechanism 4 and faces the paper stack storage area. The pin 6 is slidably connected to the translation end of the second translation mechanism 4 and is driven to extend and retract by a drive mechanism installed on the translation end of the second translation mechanism 4, so that the pin 6 can enter the paper stack storage area. In this embodiment, the drive mechanism is a cylinder 7, and the outer end of the drive column of the cylinder 7 is provided with a mounting hole, into which the pin 6 is inserted.

[0036] The first translation mechanism 2, the lifting mechanism 3, and the second translation mechanism 4 are all used to adjust the position of the industrial camera 5 and the pin 6 in the vertical plane.

[0037] In practical use, the first translation mechanism 2 is driven to adjust the initial position of the insert pin 6 in the left and right directions of the vertical plane according to the size of the corrugated paper. Then, the lifting mechanism 3 is used to adjust the position that needs to be layered. This position determination is achieved with the assistance of the vision detection function of the industrial camera 5, so that the insert pin 6 is aligned with the perforated side of the corrugated paper at a specific height.

[0038] Continue to control the second translation mechanism 4 to fine-tune the left and right positions of the pin 6 so that the pin 6 is aligned with the side hole of the corrugated paper. This position determination is also achieved with the assistance of the visual inspection function of the industrial camera 5.

[0039] Then, cylinder 7 drives pin 6 into the side hole. Lifting mechanism 3 drives pin 6 to move upward, lifting the corrugated paper, so that a gap is formed between the corrugated paper connected to pin 6 and the corrugated paper below, thus facilitating the transfer by the clamping mechanism.

[0040] The two detection and layering mechanisms operate independently but can also be used in conjunction. They can either use a single pin 6 to lift the corrugated paper or use both pins 6 to lift the corrugated paper simultaneously.

[0041] Preferably, the first translation mechanism 2 includes a multi-stage slide 20 connected to a multi-stage scissor linkage mechanism.

[0042] The multi-stage slides 20 are arranged vertically, and linear guide rails connect adjacent slides 20, so that the multi-stage slides 20 can be folded into a vertical side-by-side shape or unfolded into a stepped shape. The slide 20 at the starting end of the multi-stage slides 20 is fixed to the frame 1, and the slide 20 at the ending end of the multi-stage slides 20 is fixedly connected to the lifting mechanism 3.

[0043] The multi-stage scissor lift mechanism includes a first link 21, a second link 22, a movable shaft 23, and a fixed shaft 24. The number of the first link 21, the second link 22, the movable shaft 23, and the fixed shaft 24 are determined according to the number of slides 20. In this embodiment, there are four slides 20, and the number of the first link 21, the second link 22, the movable shaft 23, and the fixed shaft 24 is also four.

[0044] Four first links 21 are arranged in a scissor-like configuration. The two first links 21 that cross in the middle are rotatably connected to the movable shaft 23, and the two first links 21 that cross at the ends are also rotatably connected to the movable shaft 23. The movable shaft 23 connecting the starting and ending ends of the multi-stage scissor linkage mechanism is rotatably connected to the second links 22. The outer ends of the two second links 22 at the same end are rotatably connected to the fixed shaft 24. The four fixed shafts 24 are respectively fixed to the sides of the slide table 20, so that the multi-stage slide table 20 and the multi-stage scissor linkage mechanism form a linkage structure. No additional limiting mechanism is needed between the slide tables 20. The sliding range of the slide table 20 can be controlled by the swing stroke range of the multi-stage scissor linkage mechanism alone. This makes the first translation mechanism 2 more stable when folded, with higher support strength, and occupies less space when folded, while providing sufficient left and right stroke range when unfolded.

[0045] The deformation of the multi-stage scissor linkage mechanism is locked by screwing a locking cap 25 onto the fixed shaft 24 or the movable shaft 23. By rotating the locking cap 25, the locking cap 25 clamps the first link 21 or the second link 22, forming a locking function. This locking method is quick and convenient.

[0046] Preferably, a locking cap 25 is screwed onto the movable shaft 23 at the end of the multi-stage scissor linkage mechanism.

[0047] Preferably, the lifting mechanism 3 includes a connecting frame 30, a lifting platform 31, and a conveyor belt. The lifting platform 31 is vertically slidably connected to the connecting frame 30 via a linear guide rail. The conveyor belt includes an upper toothed wheel 32, a lower toothed wheel 33, a second motor 34 that drives the upper roller to rotate, and a toothed belt 35 that drives the upper roller and the lower roller to move synchronously. The lifting platform 31 is fastened to the toothed belt 35 by a locking block. When the second motor 34 drives the toothed belt 35 to move, it drives the lifting platform 31 to move up and down synchronously.

[0048] The second translation mechanism 4 includes a movable platform 40 and a first motor 41. The movable platform 40 is slidably connected to the bottom of the lifting platform 31 via a linear guide rail. A rack 42 is fixedly connected to the movable platform 40, extending in the left-right direction. The first motor 41 is fixed to the lifting platform 31, and a gear 43 is coaxially fixed to the motor shaft of the first motor 41, meshing with the rack 42. The first motor 41 drives the gear 43 to rotate along the rack 42, thereby realizing the left-right movement of the movable platform 40.

[0049] In this embodiment, the frame 1 includes a frame body, on which a first limiting frame and a second limiting frame are mounted. The limiting surfaces of the first limiting frame and the second limiting frame are perpendicular. There are two second limiting frames, which are symmetrically arranged. The first limiting frame and the two second limiting frames enclose a paper stack storage area. The first limiting frame and the second limiting frame form an XY plane limiting area, allowing the paper stack to be positioned and placed within this area.

[0050] Furthermore, the first limiting frame includes a first mounting plate 10, a second mounting plate 11, and a first limiting rod 12. The first mounting plate 10 is slidably connected to the top of the frame 1 via a linear guide rail. The second mounting plate 11 is slidably connected to the side of the first mounting plate 10 via a linear guide rail. There are two second mounting plates 11. The first limiting rod 12 is slidably connected to the outside of the second mounting plate 11 via a linear guide rail. The first limiting rod 12 is provided with a limiting plane.

[0051] The front-to-back position is adjusted by sliding the first mounting plate 10 on the frame 1, the left-to-right position is adjusted by sliding the second mounting plate 11 on the first mounting plate 10, and the height position is adjusted by sliding the first limiting rod 12 on the second mounting plate 11. This allows for the storage of corrugated paper of different specifications and ensures that the paper stacks are stored neatly. After the positions of the first mounting plate 10, the second mounting plate 11, and the first limiting rod 12 are adjusted, they are locked in place by tightening the locking bolts.

[0052] Furthermore, the second limiting frame includes a sliding frame 13, a sliding rod 14, a second limiting rod 15, and a push-pull rod 16. The frame 1 is provided with two vertically parallel guide rods that extend forward and backward. The sliding frame 13 is slidably connected to the guide rods, allowing the sliding frame 13 to move forward and backward. There are two sliding rods 14, which are vertically parallel and slidably connected to the sliding frame 13 in the left-right direction. The second limiting rod 15 is vertically arranged and fixed to the inner end of the sliding rod 14, while the outer end of the sliding rod 14 is fixed to the push-pull rod 16.

[0053] The front-to-back position is adjusted by sliding the sliding frame 13 on the frame 1, and the left-to-right position is adjusted by sliding the sliding rod 14 on the sliding frame 13, thereby satisfying the limiting position adjustment of the second limiting rod 15. This meets the storage needs of corrugated paper of different specifications and ensures that the paper stacks are stored neatly. By pushing the two push-pull rods 16 in opposite directions, the paper stacks in the area can be aligned left and right, and the paper stacks are reshaped.

[0054] Furthermore, the sliding rod 14 has a telescopic function. Its structure includes a first rod body 140 and a second rod body 141 slidably sleeved within the first rod body 140. The first rod body 140 is slidably connected to a third mounting plate, and a second limiting rod 15 is fixedly connected to the second rod body 141. After the first rod body 140 is slidably adjusted, it is tightened by a locking bolt. By adjusting the length of the sliding rod 14, it can further adapt to the limiting needs of paper stacks of different specifications.

[0055] Furthermore, a limiting plate 300 is fixedly attached to the side of the connecting frame 30 facing the paper stack storage area. The limiting surface of the limiting plate 300 is the positioning reference surface. By driving the first mounting plate 10 to slide, the first limiting rod 12 can be driven to move toward the limiting plate 300, thereby aligning the paper stacks in the area and performing secondary shaping on the paper stacks.

[0056] Example 2

[0057] The difference between this embodiment and Embodiment 1 is that, as shown in Figure 6, a sliding sleeve 44 is installed on the moving platform 40. The driving mechanism includes a guide post 70 slidably connected within the sliding sleeve 44 and a cylinder 7 that drives the guide post 70. A slot is provided at the end of the guide rod facing the paper stacking area; preferably, the slot is a fan-shaped slot 45. A rotating shaft 46 is vertically fixed to the inner side of the fan-shaped slot 45. The inner end of the pin 6 is rotatably connected to the rotating shaft 46, allowing the pin 6 to swing horizontally. Elastic elements are connected between the left and right sides of the pin 6 and the inner wall of the fan-shaped slot 45, driving the pin 6 to be coaxial with the guide rod. In this embodiment, the elastic element is a compression spring 47, which elastically supports one side of the pin 6 between the pin 6 and the inner wall of the fan-shaped slot 45. Two compression springs 47 simultaneously and elastically press against the pin 6, ensuring that the pin 6 is coaxial with the guide rod in the initial state. As the pin 6 gradually enters the side hole of the corrugated paper, even if the side hole and the pin 6 are not aligned, when the pin 6 touches the inner wall of the side hole, it will not pierce the corrugated paper, but will shift horizontally. This prevents the pin 6 from being pulled off a single layer of the corrugated paper after it is inserted into the corrugated paper and then being pulled off a single layer as the pin 6 resets.

[0058] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the scope of protection of this invention.
