Description

Technical Field

[0001] This invention relates to the field of cardboard processing, and more particularly to an intelligent cardboard palletizer for logistics and transportation. Background Art

[0002] After cardboard is cut, it is usually stacked by conveyor belt for easy transport. For long cardboard (more than two meters in length), after the front end of the cardboard leaves the conveyor belt, it comes into contact with the stacking table and generates frictional resistance. The frictional force is greater than the frictional force between the rear end of the cardboard and the conveyor belt. As a result, the rear end of the cardboard that has not left the conveyor belt will slide relative to the conveyor belt, making it impossible for the rear end of the cardboard to leave the conveyor belt. When subsequent long cardboards are transported, they will collide and pile up with the cardboard that has not left the conveyor belt, making it impossible to stack. In addition, the cardboard itself is flexible, and multiple long cardboards colliding with each other will cause the cardboard to deform and be damaged. Summary of the Invention

[0003] To overcome the drawbacks of long cardboard, where the frictional resistance generated when the front end detaches from the conveyor belt contacts the stacking table is greater than the frictional force between the rear end of the cardboard and the conveyor belt, preventing the rear end of the cardboard from leaving the conveyor belt, causing subsequent long cardboard to collide and pile up with the detached cardboard, thus hindering the stacking process, and causing multiple long cardboards to collide with each other, resulting in deformation and damage, this invention provides an intelligent cardboard palletizing machine for logistics transportation.

Several first guide rails are fixedly connected to each first connecting rod and each second connecting rod. A first electric slider is connected to each first guide rail.

Another mounting block is fixedly connected to the first electric sliders on the same second connecting rod. The mounting block is fixedly connected to the corresponding connecting frame. Two second guide rails are connected to the first support frame. A second electric slider is connected to each second guide rail. A telescopic rod is connected to each second electric slider. The telescopic end of each telescopic rod is rotatably connected to a first connecting rod.

[0007] As an improvement to the above scheme, it also includes a guide sleeve; a guide sleeve is connected to each conveying roller 2; a spiral part is provided on the surface of the guide sleeve; a second insertion block is provided on the guide sleeve; a sliding groove is opened on the conveying roller 2; the second insertion block is slidably connected to the sliding groove.

[0008] As an improvement to the above solution, it also includes a fixing ring; a fixing ring is connected to the second connecting shaft corresponding to the second conveyor roller; a fixing block is fixedly connected to the connecting frame corresponding to the second conveyor roller; an elastic rope is fixedly connected to the fixing block; the elastic rope is fixedly connected to the fixing ring; a rotating ring is connected to the fixing ring; the rotating ring is fixedly connected to the corresponding guide sleeve; a first insertion block is fixedly connected to the fixing ring; an installation groove is opened on the second connecting shaft; the first insertion block is slidably connected to the installation groove; and an elastic element is connected between the first insertion block and the inner wall of the installation groove.

[0014] Beneficial effects: When placing long cardboard for stacking, the left end of the cardboard first contacts the surface of the second conveyor belt, and then it is placed completely on the second conveyor belt from left to right, which ensures the stability of the long cardboard. Compared with placing the long cardboard horizontally, the long cardboard has a large area, and the air resistance on the bottom surface of the long cardboard can easily cause it to deflect and misalign when it is placed. Therefore, the method of placing long cardboard in the stacking of the present invention is more precise and has better stability. The front conveyor roller group contacts the front side of the long cardboard, and the rear conveyor roller group contacts the rear side of the long cardboard, pushing the uneven long cardboards to move and position, so that the front and rear positions of the long cardboards are consistent, which is convenient for subsequent packaging work; After the skewed long cardboard is conveyed to the conveyor roller assembly, the skewed side of the long cardboard will cover the spiral part of the guide sleeve corresponding to the skewed direction. Then, when the spiral part contacts the long cardboard, it rotates and pushes the skewed side of the long cardboard towards the middle, correcting the long cardboard to a non-skewed state and preventing the long cardboard from skewing to one side. When the conveyor roller assembly puts down the long cardboard, the long cardboard is unevenly stressed and tilts to the front or back side when it falls, deviating from the predetermined stacking position. By using a limiting component to ensure that the left end of each long cardboard is in the same position before it is placed down for stacking, the final position of the long cardboard will not deviate slightly to the left or right. Push the left end of the long cardboard downwards by pressing down with the pressure block to prevent the left end of the long cardboard from getting stuck on the baffle and being unable to fall.

[0024] Both conveyor roller 71 and conveyor roller 72 have a rubber layer on their surfaces to increase friction and prevent slippage when conveying long cardboard 1111.

[0025] When long cardboard 1111 is stacked via a conveyor belt, the front end of the cardboard 1111 detaches from the conveyor belt and contacts the stacking table. The resulting frictional resistance is greater than the frictional force between the rear end of the cardboard 1111 and the conveyor belt, causing the rear end of the cardboard 1111 to be unable to detach from the conveyor belt. When subsequent long cardboard 1111 are conveyed, they will collide and pile up with the cardboard 1111 that has not detached, making the stacking work impossible. Furthermore, the collision of multiple long cardboard 1111 will cause the cardboard 1111 to deform and be damaged.

[0026] To address the above problems, this invention provides an intelligent cardboard palletizer for logistics and transportation.

[0027] The first conveyor belt 010 is used to convey the long cardboard 1111 for palletizing, and the second conveyor belt 020 is used to support the long cardboard 1111 for palletizing. The conveying directions of the two are perpendicular, and the width of the second conveyor belt 020 is greater than the length of the long cardboard 1111; in the initial state, the first electric push rod 101 is in a retracted state, the second connecting rod 3 is inclined, and the first connecting rod 2 is horizontal.

[0028] For the convenience of description, the conveying roller 1 71 and the conveying roller 2 72 are collectively referred to as a conveying roller set hereinafter.

[0029] When stacking long cardboard 1111, Figure 1 As shown, the first conveyor belt 010 conveys the long cardboard 1111 from right to left. After the left end of the long cardboard 1111 leaves the first conveyor belt 010, it moves to the conveyor roller group on the first connecting rod 2, and continues to move to the left under the conveyor belt 010 to the conveyor roller group on the second connecting rod 3. During the movement of the long cardboard 1111 on each conveyor roller group, the friction force when in contact with the long cardboard 1111 is reduced by the rotation of the conveyor roller group, preventing the long cardboard 1111 from being unable to continue moving to the left. After the left end of the long cardboard 1111 passes the conveyor roller group on the first connecting rod 2, it is conveyed to the conveyor roller group on the second connecting rod 3. The second connecting rod 3 is inclined, and the long cardboard 1111 itself has a certain degree of flexibility. Therefore, under the action of gravity, the left end of the long cardboard 1111 bends downward and contacts the conveyor roller group on the second connecting rod 3 to continue moving until the right end of the long cardboard 1111 leaves the first conveyor belt 010. After 010, all electric motors 102 are controlled to work sequentially from left to right. The electric motors 102 drive the corresponding first connecting shaft 5 to rotate, causing the first connecting shaft 5 to drive the corresponding second connecting shaft 6 to flip downward. The second connecting shaft 6 drives the corresponding conveyor roller 1 71 and the corresponding conveyor roller 2 72 to flip downward, thereby gradually lowering the long cardboard 1111 from left to right and placing it on the second conveyor belt 020. In this way, the left end of the long cardboard 1111 first contacts the surface of the second conveyor belt 020, and then it is completely placed on the second conveyor belt 020 from left to right, ensuring the stability of the long cardboard 1111. Compared with the long cardboard 1111 being placed horizontally, the long cardboard 1111 has a large area, and the air resistance on the bottom surface of the long cardboard 1111 is easy to cause it to deflect and misalign when it is lowered. Therefore, the method of stacking and placing the long cardboard 1111 in this invention is more accurate and has better stability.

[0030] After the conveyor roller assembly flips downwards to place the long cardboard 1111, the electric motor 102 is controlled to drive the first connecting shaft 5 to reset. The first connecting shaft 5 drives the second connecting shaft 6 and the conveyor roller assembly to rotate and reset, preparing to convey the second long cardboard 1111. At the same time, the first electric push rod 101 is controlled to extend upwards, so that the second connecting rod 3 rotates around the connection point with the first connecting rod 2, reducing the tilt angle of the second connecting rod 3 and causing the conveyor roller assembly on the second connecting rod 3 to move upwards as a whole, making it easier for the second long cardboard 1111 to be stacked on the first long cardboard 1111 for stacking. Thus, each time a long cardboard 1111 is placed, the second connecting rod 3 rotates upwards once until the second connecting rod 3 is in a horizontal state, completing one complete stacking of long cardboard 1111. Then, the second conveyor belt 020 is controlled to work, conveying the stacked long cardboard 1111 forward and moving it out of the stacking area. Then, the workers carry out subsequent packaging and other processing on the stacked long cardboard 1111. At the same time, the first conveyor belt 010 continues to output long cardboard 1111, and the invention continues the stacking work.

[0031] It should be noted that when the right end of the long cardboard 1111 is about to leave the first conveyor belt 010, the micro motor is controlled to drive the conveyor roller 2 72 to work, and the conveyor roller 2 72 continues to drive the long cardboard 1111 to move a distance to the left, so that the right end of the long cardboard 1111 is away from the first conveyor belt 010, avoiding the right end of the long cardboard 1111 from staying on the first conveyor belt 010.

[0032] During the conveying of long cardboard 1111 by the first conveyor belt 010, there is a slight deviation in the front-to-back position of each long cardboard 1111 on the first conveyor belt 010. Consequently, after the long cardboard 1111 is stacked, the front-to-back positions of each long cardboard 1111 are uneven. Therefore, when all conveyor roller groups are in a vertical state with downward flipping, the second electric slider 25 is controlled to move downward along the second guide rail 24. The second electric slider 25 drives the right end of the corresponding first connecting rod 2 to move downward. Then, the first connecting rod 2 rotates downward with the connection point with the left end of the fixed rod 1 as the rotation point until the second electric slider 25 moves to the limit position, so that the conveyor roller groups on the first connecting rod 2 are in an inclined arrangement. Afterward, the first electric slider 22 on the first connecting rod 2 and the second connecting rod 3 is controlled to move along the first guide rail 21 toward the stacked long cardboard 1111. The first electric slider 22 drives the corresponding mounting block 23 to move, and the mounting block 23 drives the corresponding connecting... The connecting frame 4, the first connecting shaft 5, the second connecting shaft 6, and the conveying roller group move towards the long cardboard 1111. The front conveying roller group contacts the front side of the long cardboard 1111, and the rear conveying roller group contacts the rear side of the long cardboard 1111, pushing the uneven long cardboard 1111 to move and position, so that the front and rear positions of each long cardboard 1111 are consistent, which is convenient for subsequent packaging work. The conveying roller group on the first connecting rod 2 is arranged at an angle and can contact the long cardboard 1111 at different heights after stacking, thereby ensuring that all stacked long cardboard 1111 are pushed and aligned. After the positioning work is completed, all parts are reset, and the next long cardboard 1111 is conveyed and stacked. Compared with the existing technology that sets up an additional pushing mechanism to push the stacked cardboard, the present invention not only uses the conveying roller group for conveying the long cardboard 1111, but also for correcting the neat stacking of the long cardboard 1111. It has a compact structure, occupies little space, and is highly practical.

[0033] It should be noted that there is a buffer distance between each long cardboard 1111 conveyed by the first conveyor belt 010, so as to provide buffer time for the operation of each part of the present invention.

[0034] Because the first conveyor belt 010 lacks a positioning mechanism, the long cardboard 1111 exhibits a slight forward or backward skew during its transport on the first conveyor belt 010 due to equipment vibration and other factors. As the skewed long cardboard 1111 detaches from the first conveyor belt 010, the skew becomes increasingly severe as the left end of the long cardboard 1111 moves closer to the conveyor rollers, eventually causing the long cardboard 1111 to lose contact with some of the conveyor rollers. When the conveyor rollers 1 or 72 contact and then lower the long cardboard 1111 for stacking, the uneven force on the long cardboard 1111 will cause it to tilt forward or backward as it falls. The tilted long cardboard 1111 will deviate significantly from the predetermined stacking position in both forward and backward directions. Consequently, when the conveyor rollers place the next long cardboard 1111 and flip it downwards, the conveyor rollers are easily blocked by the deviated long cardboard 1111, preventing the conveyor rollers from flipping smoothly and affecting the overall stacking of the long cardboard 1111. The cardboard 1111, when normally conveyed on the first conveyor belt 010, contacts the contact surfaces 7001 of each conveyor roller 1 71 and conveyor roller 2 72 and moves to the left. When the cardboard 1111 becomes skewed and moves onto conveyor roller 2 72, the skewed side of the cardboard 1111 will cover the spiral portion 9001 of the guide sleeve 9 in the corresponding skew direction. Since the guide sleeve 9 is rotated by conveyor roller 2 72, the spiral portion 9001 of the guide sleeve 9 spirals towards the cardboard 1111. The spiral part 9001 is located in the middle of the 11 section. When it rotates and contacts the long cardboard 1111, it pushes the offset side of the long cardboard 1111 towards the middle, thereby correcting the offset long cardboard 1111 until the front and rear sides of the long cardboard 1111 are in contact with the contact surface 7001, and it is corrected to a non-offset state. This prevents the long cardboard 1111 from tilting to one side. When the conveyor roller group puts down the long cardboard 1111, the long cardboard 1111 is subjected to uneven force and tilts to the front or rear side when it falls, deviating from the predetermined stacking position.

[0035] When the second conveyor roller 72 flips to a vertical position to push and align the stacked long cardboard 1111, the spiral part 9001 of the guide sleeve 9 is uneven. If it comes into contact with the long cardboard 1111, it will cause a counter-effect on the alignment, affecting the neatness of the stacking of the long cardboard 1111. Therefore, the guide sleeve 9 is connected to the connecting frame 4 by the fixing block 4001, the elastic rope 4002, and the fixing ring 8. When the second conveyor roller 72 flips downward, the elastic rope 4002 restricts the fixing ring 8, thereby pulling the fixing ring 8 to slide on the second connecting shaft 6. The first insertion block 8002 slides in the mounting groove 6001 towards the first connecting shaft 5. At the same time, the first insertion block 8002 squeezes the elastic element 8003. The sliding of the fixing ring 8 drives the rotating ring 8001 and the guide sleeve 9 to slide. The second insertion block 9002 slides in the sliding groove 7002 towards the second connecting shaft 6. Finally, when the second conveyor roller 72 flips to a vertical position, as Figure 8As shown, the fixing ring 8 and the guide sleeve 9 are closer to the first connecting shaft 5, thereby exposing the contact surface 7001 of the second conveyor roller 72, which was originally covered by the guide sleeve 9, increasing the length of the contact surface 7001 in the vertical direction. At this time, the contact surface 7001 of the conveyor roller group contacts the long cardboard 1111 for pushing and positioning, while the spiral part 9001 does not contact the long cardboard 1111. By sliding the spiral part 9001 to avoid the contact surface 7001, the height of the long cardboard 1111, which can be adjusted and stacked neatly in one go, is higher, thus improving the stacking efficiency.

[0036] Example 2 Based on Example 1, such as Figure 5 and Figure 10-11 As shown, it also includes a limiting component, which includes a motor 33, a third connecting rod 34 and a baffle 35; each second connecting rod 3 is connected to a motor 33; each motor 33 output shaft is fixedly connected to a third connecting rod 34; a baffle 35 is fixedly connected between the two third connecting rods 34.

[0037] The limiting assembly also includes a third guide rail 31 and a third electric slider 32; a third guide rail 31 is bolted to the upper side of each second connecting rod 3; a third electric slider 32 is slidably connected to each third guide rail 31; a motor 33 is bolted to each third electric slider 32; thereby, the relevant parts are moved along the third guide rail 31 by the third electric slider 32, and the position of the baffle 35 is adjusted to adapt to long cardboard 1111 of different lengths.

[0038] The limiting assembly also includes a mounting frame 41, a second electric push rod 42 and a pressure block 43; the mounting frame 41 is mounted on the upper side of the baffle 35; two second electric push rods 42 are mounted on the mounting frame 41; and the telescopic ends of all the second electric push rods 42 are fixedly connected to a pressure block 43.

[0039] The lower side of the pressure block 43 is made of rubber to prevent damage to the long cardboard 1111.

[0040] When the long cardboard 1111 moves to the left on the conveyor roller assembly, if no conveying limit is set at the left end, the final stopping position of the long cardboard 1111 will have a slight deviation to the left or right. Therefore, when the long cardboard 1111 moves to the left on each conveyor roller assembly, the left end of the long cardboard 1111 will eventually contact the baffle 35 and stop moving to the left. Then, the conveyor roller assembly is controlled to put the long cardboard 1111 down, thereby ensuring that the left end of each long cardboard 1111 is in the same position before being put down for stacking, avoiding a slight deviation to the left or right at the final stopping position of the long cardboard 1111.

[0041] In addition, depending on the length of the long cardboard 1111, the user can control the third electric slider 32 to move left or right along the third guide rail 31, thereby adjusting the position of the limiting component to change the final stopping position of the left end of the long cardboard 1111.

[0042] It should be noted that as the second connecting rod 3 changes its tilt angle, the motor 33 synchronously drives the third connecting rod 34 to rotate, so that the baffle 35 always remains vertical, avoiding the baffle 35 from tilting and causing the left end of the long cardboard 1111 to be mispositioned.

[0043] When the left end of the long cardboard 1111 is lowered, it contacts the baffle 35. Due to the friction between the thin cardboard 1111 and the baffle 35, the left end of the cardboard 1111 may become stuck against the baffle 35 and unable to fall. Therefore, while the conveyor roller group flips to lower the left end of the cardboard 1111, the second electric push rods 42 on the mounting frame 41 are controlled to extend downward, causing the pressure block 43 to contact the upper surface of the left end of the cardboard 1111 and push the left end of the cardboard 1111 downward, so that the left end of the cardboard 1111 falls smoothly and avoids the left end of the cardboard 1111 getting stuck on the baffle 35 and unable to fall. Afterward, the second electric push rods 42 are controlled to retract, causing the pressure block 43 to reset, and the operation is repeated when the next long cardboard 1111 is stacked.

[0044] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, all equivalent changes made to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
