[0029] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0030] Example 1: Reference Figure 1-9 As shown, an automatic carton stacking and shaping device of this embodiment includes a unloading roller line 1, an outlet end of the unloading roller line 1 is connected to a unloading pushing platform 2, and an outlet end of the unloading pushing platform 2 is connected to a shaping platform 3;

[0031] The unloading and pushing platform 2 includes a feeding roller line 21, a partition plate 22 and a pushing rod 24. The feeding roller line 21 is installed in the middle of the upper end of the unloading and pushing platform 2. There are multiple groups of partition plates 22, all of which are installed in the middle of the feeding roller line 21. There are two groups of pushing rods 24, and both are driven by chain rails 26 to rotate around the periphery of the feeding roller line 21.

[0032] The cartons are continuously conveyed by the feeding roller line 21, so that multiple cartons can be brought into contact with each other and arranged in a row. The multiple sets of partition plates 22 can separate the cartons, thereby facilitating the shaping of the cartons by the shaping platform 3. When all the cartons are placed, the pusher rod 24 rotates under the drive of the chain track 26, and the pusher rod 24 pushes the carton from the back, causing the carton to move onto the shaping platform 3.

[0033] In some examples, the chain rail 26 is rotatably installed in the middle of both ends of the unloading pushing platform 2, and two groups of pushing rods 24 are evenly distributed on the outer surface of the chain rail 26. Support rods 25 are provided at the bottom of both ends of the pushing rod 24. The support rods 25 are fixedly installed on the outer end of the chain rail 26. The chain rail 26 is rotated to drive the pushing rod 24 to rotate around the periphery of the unloading pushing platform 2, thereby pushing the cartons placed on the unloading pushing platform 2, so that the cartons are moved to the shaping platform 3 to wait for shaping.

[0034] In some examples, a lifting cylinder 23 is provided at the bottom of the partition plate 22. The lifting cylinder 23 is provided in the middle of the bottom end of the feeding roller line 21. The partition plate 22 can be driven by the lifting cylinder 23 to move up and down in the middle of the feeding roller line 21. When the partition plate 22 is in the rising state, the cartons are separated. When the partition plate 22 is in the descending state, there is no separation between the cartons. They will be close to each other and arranged in a row. For specific structural diagrams, please refer to Figure 9 shown.

[0035] In some examples, a baffle 27 is provided on the upper right side of the unloading and pushing platform 2, and the baffle 27 is provided at the end of the feeding roller line 21. The baffle 27 can be used to block the cartons so that the cartons remain on the feeding roller line 21, so that multiple groups of cartons can be arranged in a row close to each other.

[0036] Example 2: Reference Figure 1 - Figure 9 As shown, based on Example 1, a carton automatic stacking and shaping device also includes the following structure:

[0037] The shaping platform 3 includes a roller assembly 31, a left positioning bar 33 and a right positioning bar 34. The roller assembly 31 is composed of multiple groups of rollers. The roller assembly 31 is installed on the upper end surface of the shaping platform 3. The left positioning bar 33 and the right positioning bar 34 are distributed on both sides of the upper end of the roller assembly 31. The left positioning bar 33 is slidably installed in the middle of the left end of the shaping platform 3, and the right positioning bar 34 is slidably installed in the middle of the right end of the shaping platform 3; the shaping platform 3 also includes an alignment push rod 32, which is slidably installed in the middle of the roller assembly 31 and is located at the outlet end of the shaping platform 3.

[0038] Among them, multiple groups of cartons can be clamped and positioned from the left and right sides of the carton through the left positioning bar 33 and the right positioning bar 34, so that the left and right sides of the carton are arranged neatly and are in the same line, thereby realizing the shaping of the carton, and then the alignment push rod 32 can be used to push the carton in the direction of the exit end, so that the front and back sides of the carton are also arranged neatly and are in the same line, thereby realizing the shaping of the carton.

[0039] The bottom transmission of the left positioning bar 33 is connected to the second screw rod 332, and the second screw rod 332 is driven by the second servo motor 331. The second servo motor 331 drives the second screw rod 332 to rotate, and the left positioning bar 33 can be driven to move toward the center position of the shaping platform 3, thereby pushing the left side of the carton.

[0040] A pushing cylinder 341 is provided on the right side of the bottom end of the shaping platform 3. The output end of the pushing cylinder 341 is connected to the bottom of the right positioning bar 34. By pushing the cylinder 341 to perform telescopic movement, the right positioning bar 34 can be driven to move. When the right positioning bar 34 moves outward, it facilitates the movement of the carton onto the shaping platform 3, and then moves toward the center direction of the shaping platform 3 through the right positioning bar 34, thereby pushing the right side of the carton, so that the right side of the carton is arranged neatly.

[0041] A sliding block 321 is provided at the bottom of the alignment push rod 32, and the sliding block 321 is slidably installed in the middle of the bottom end of the roller assembly 31. The bottom of the sliding block 321 is transmission-connected with a first screw rod 323, and the first screw rod 323 is driven by a first servo motor 322. The first servo motor 322 drives the first screw rod 323 to rotate, thereby driving the sliding block 321 to slide. When the alignment push rod 32 slides inward, the outlet end of the carton is pushed, so that the front and back of the carton are arranged neatly.

[0042] In some examples, multiple sets of rollers are provided at the inner ends of the baffle 27, the left positioning bar 33 and the right positioning bar 34. The setting of the rollers facilitates the movement of the carton and avoids hard contact between the carton and the baffle 27, the left positioning bar 33 and the right positioning bar 34, which causes scratches on the outer surface of the carton during movement.

[0043] In some examples, the unloading roller line 1 and the feeding roller line 21 are both driven by asynchronous motors to rotate.

[0044] The working principle of this utility model is:

[0045] When cartons need to be transported and palletized, the cartons are first transported one by one through the unloading roller line 1 to the unloading pushing platform 2. At this time, the feeding roller line 21 will continue to transport the cartons to the baffle 27 on the right side, so that multiple cartons can be arranged in a row on the unloading pushing platform 2. At this time, the pushing rod 24 will move in a circle under the drive of the chain rail 26. The pushing rod 24 rotates to push the cartons arranged in a row on the unloading pushing platform 2, so that the cartons are moved to the shaping platform 3.

[0046] Through the above steps, the cartons are continuously conveyed and then arranged. When all the cartons are moved onto the shaping platform 3, the left positioning bar 33 and the right positioning bar 34 are moved inwards to clamp the two ends of the cartons, so that the cartons are close to each other and arranged neatly.

[0047] The specific steps are as follows: the second servo motor 331 drives the second screw rod 332 to rotate, thereby driving the left positioning bar 33 to move toward the right direction, thereby pushing the left side of the carton, so that the left sides of multiple groups of cartons are in a straight line and arranged neatly; at the same time, by starting the pushing cylinder 341, the right positioning bar 34 is driven to move toward the left direction, thereby pushing the right side of the carton, so that the right sides of multiple groups of cartons are in a straight line and arranged neatly; then, by starting the first servo motor 322, the first screw rod 323 is driven to rotate, thereby driving the alignment push rod 32 to move from the outlet end toward the inside, thereby aligning the position of the cartons close to the outlet end, so that they are arranged in a line.

[0048] In the above structure, through the left positioning bar 33, the right positioning bar 34 and the alignment push rod 32, multiple groups of cartons can be moved and aligned left and right and front and back in turn, so as to realize the shaping of the cartons. When the cartons are shaped, they can be moved to the pallet by the robot for stacking.

[0049] In addition, by providing multiple sets of partition plates 22 in the middle of the feeding roller line 21, when the number of cartons is not equal and it is difficult to arrange them, the partition plates 22 can be used to separate the cartons. For the specific structure, please refer to Figure 9 In Figure a, the six cartons cannot be arranged into a neat square due to the size of the pallet, and can only be arranged into irregular shapes. Therefore, the irregular shapes need to be reshaped. The left positioning bar 33, the right positioning bar 34 and the alignment push rod 32 are mainly used to reshape the left and right and front and back of the cartons so that the four sides of the irregular shape are in the same line, thereby obtaining Figure 9 The structure in Figure b is used to complete the shaping of the cartons, so that the outer edges of multiple groups of cartons are aligned, making it convenient for the robot to stack the entire layer of products from the shaping platform 3 onto the pallet.

[0050] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
