Then, the lifting plate 503 drives the first air cylinder 505 to rise, and then the material supporting block 501 lifts this group of cartons. When the feeding belt 1 conveys the next group of cartons between the two material supporting mechanisms 5, the first baffle positioning plate 4 positions this group of cartons on the feeding belt 1, and the first air cylinder 505 drives the material supporting block 501 to retract, so that the previous group of cartons is stacked on the upper side of this group of cartons, forming two groups of cartons. Then, the lifting plate 503 drives the first air cylinder 505 to descend, the first air cylinder 505 drives the material supporting block 501 to protrude out of the through groove 504, so that the material supporting block 501 is placed under the two groups of cartons. Then, the lifting plate 503 drives the first air cylinder 505 to rise, and then the material supporting block 501 lifts the two groups of cartons. Finally, the robotic arm 2 drives the clamping mechanism 3 to clamp the two groups of cartons onto the pallet 12 for palletizing at the same time, improving the palletizing efficiency.

[0025] In order to facilitate driving the lifting plate 503 to lift and lower, in this embodiment, preferably, a screw rod 506 is connected to the middle of the lifting plate 503 by means of threads. A motor 507 is provided at the top of the machine case 502. The output end of the motor 507 passes through the machine case 502 and is connected to the screw rod 506.

[0026] In order to facilitate supporting the edge of each group of cartons, improving the smoothness of carton conveying, and preventing the edge of the carton from bending downward, and further ensuring that the material supporting block 501 can protrude and be placed under each group of cartons, in this embodiment, preferably, a plurality of rollers 508 are rotatably connected to one side of the machine case 502 close to the feeding belt 1. The top ends of the rollers 508 are on the same horizontal plane as the top surface of the feeding belt 1. The purpose is to support the edge of each group of cartons through the rollers 508 while the feeding belt 1 conveys each group of cartons, so that the rollers 508 roll on the lower side surface of the carton edge opposite to them, improving the smoothness of carton conveying, and preventing the edge of the carton from bending downward, and further ensuring that the material supporting block 501 can protrude and be placed under each group of cartons.

[0027] In order to facilitate adjustment according to cartons of different sizes and improve applicability, in this embodiment, preferably, the material supporting mechanism 5 further includes a base 509. A slide rail 510 is connected to the top of the base 509. A slide block 511 is connected to the bottom of the machine case 502. The slide block 511 is slidably connected to the slide rail 510. The purpose is that when palletizing cartons of different sizes, push the machine case 502 to make the slide block 511 slide along the slide rail 510, and then adjust the relative distance between the two material supporting mechanisms 5 to be applicable to cartons of different sizes.

[0028] In order to facilitate improving the positioning accuracy of each group of cartons, in this embodiment, preferably, a second material blocking and positioning plate 6 is provided on the front side of the feeding belt 1, a feeding rack 7 is provided on the front side of the second material blocking and positioning plate 6, and a second air cylinder 8 is connected to its bottom. Pushing and positioning plates 9 are symmetrically provided on both sides of the feeding rack 7, and a third air cylinder 10 is connected to the side of the pushing and positioning plate 9 away from the feeding rack 7. The purpose is to convey each group of cartons through the feeding rack 7 before entering the feeding belt 1, and position each group of cartons on the feeding rack 7 in the Y-axis direction through the second material blocking and positioning plate 6. Then, the third air cylinder 10 is driven to move the pushing and positioning plates 9, so that the two pushing and positioning plates 9 clamp this group of cartons to form positioning in the X-axis direction, improve the positioning accuracy of each group of cartons, and ensure that the multiple stacked cartons in each group of cartons can be aligned one by one, ensure that each group of cartons can accurately enter between the two material supporting mechanisms 5. After positioning, the third air cylinder 10 is driven to move the pushing and positioning plates 9 in the reverse direction, and at the same time, the second air cylinder 8 is driven to lower the second material blocking and positioning plate 6, so that this group of cartons is conveyed from the feeding rack 7 to the feeding belt 1.

[0029] In order to facilitate ensuring that the multiple stacked cartons in each group of cartons can be aligned one by one, in this embodiment, preferably, the feeding rack 7 includes a rack 701 and conveying rollers 702. The conveying rollers 702 are rotatably connected to the rack 701, and a plurality of them are evenly arranged. A convex block 11 is connected to the bottom of the pushing and positioning plate 9. The convex block 11 is arranged between two conveying rollers 702, and its bottom surface is lower than the top end of the conveying rollers 702. The plurality of conveying rollers 702 are sequentially connected in series through a rotary belt and driven to rotate synchronously by a motor, so as to convey each group of cartons on the plurality of conveying rollers 102. The purpose is to drive the pushing and positioning plate 9 to move through the third air cylinder 10, so that the two pushing and positioning plates 9 clamp a group of cartons, and at the same time, clamp the bottommost carton of this group of cartons through the convex block 11, preventing the pushing and positioning plate 9 from not being able to push the bottommost carton because it avoids contacting the conveying rollers 702, thereby ensuring that the multiple stacked cartons in each group of cartons can be aligned one by one and improving the positioning accuracy.

[0030] For the convenience of clamping two groups of cartons, in this embodiment, preferably, the material clamping mechanism 3 includes a mounting frame 301 and a fourth cylinder 302 mounted on the mounting frame 301. Slide rods 303 are symmetrically connected to both sides of the mounting frame 301, and clamping frames 304 are symmetrically arranged on the other two sides thereof. The clamping frames 304 are slidably connected to the slide rods 303. The output end of the fourth cylinder 302 is hinged with a first connecting rod 305 and a second connecting rod 306. The first connecting rod 305 is hinged with one of the clamping frames 304, and the second connecting rod 306 is hinged with the other clamping frame 304. Clamping plates 307 are connected to the opposite sides of the two clamping frames 304. The purpose is that the fourth cylinder 302 pulls one clamping frame 304 to slide along the slide rod 303 and pulls the other clamping frame 304 to slide along the slide rod 303 respectively through the first connecting rod 305 and the second connecting rod 306, so that the two clamping frames 304 can move towards each other and away from each other. Furthermore, when the two clamping frames 304 move towards each other, the two groups of cartons can be clamped by the two clamping plates 307, and when the two clamping frames 304 move away from each other, the two groups of cartons can be released.

[0031] In order to prevent the cartons from falling and improve the reliability when clamping the two groups of cartons, in this embodiment, preferably, a supporting strip 308 is connected to the bottom of the clamping plate 307. The purpose is to support the cartons through the supporting strip 308 when clamping the two groups of cartons, prevent the cartons from falling, and improve the reliability.

[0032] The working principle and usage process of the present utility model: Each group of cartons is conveyed by the feeding frame 7, and each group of cartons on the feeding frame 7 is positioned in the Y-axis direction by the second material blocking and positioning plate 6. Then, the third cylinder 10 drives the pushing and positioning plate 9 to move, so that the two pushing and positioning plates 9 clamp this group of cartons to form positioning in the X-axis direction, improve the positioning accuracy of each group of cartons, and ensure that the multiple stacked cartons in each group of cartons can be aligned one by one. After positioning, the third cylinder 10 drives the pushing and positioning plate 9 to move in the reverse direction, and at the same time, the second cylinder 8 drives the second material blocking and positioning plate 6 to descend, so that this group of cartons is conveyed from the feeding frame 7 to the conveyor belt 1;

[0033] When the feeding belt 1 conveys a group of cartons between the two material supporting mechanisms 5, the first baffle positioning plate 4 positions this group of cartons on the feeding belt 1. The first air cylinder 505 drives the material supporting block 501 to protrude out of the through slot 504, so that the material supporting block 501 is placed under this group of cartons. Then the lifting plate 503 drives the first air cylinder 505 to rise, and then this group of cartons is lifted by the material supporting block 501. When the feeding belt 1 conveys the next group of cartons between the two material supporting mechanisms 5, the first baffle positioning plate 4 positions this group of cartons on the feeding belt 1, and the first air cylinder 505 drives the material supporting block 501 to retract, so that the previous group of cartons is stacked on the upper side of this group of cartons, forming two groups of cartons. Then the lifting plate 503 drives the first air cylinder 505 to descend, and the first air cylinder 505 drives the material supporting block 501 to protrude out of the through slot 504, so that the material supporting block 501 is placed under the two groups of cartons. Then the lifting plate 503 drives the first air cylinder 505 to rise, and then the two groups of cartons are lifted by the material supporting block 501;

[0034] Finally, the manipulator 2 moves the clamping mechanism 3 to the two groups of cartons. Then the fourth air cylinder 302 respectively pulls a clamping frame 304 to slide along the slide rod 303 through the first connecting rod 305 and the second connecting rod 306, and pulls the other clamping frame 304 to slide along the slide rod 303, so that the two clamping frames 304 move towards each other, and the two groups of cartons are clamped by the two clamping plates 307. Then the manipulator 2 drives the clamping mechanism 3 and the two groups of cartons to move to the pallet 12 at the same time. The fourth air cylinder 302 respectively pulls a clamping frame 304 to slide along the slide rod 303 through the first connecting rod 305 and the second connecting rod 306, and pulls the other clamping frame 304 to slide along the slide rod 303, so that the two clamping frames 304 move away from each other, and then the two groups of cartons are loosened and placed on the pallet 12 for palletizing, improving the palletizing efficiency.
