The output end of the motor 35 is fixedly connected to one end of the second connecting rod 31; Specifically, in the prior art, suitcases are conveyed by means of a roller conveyor. After multiple suitcases are conveyed to a designated position, they need to be uniformly carried and the number of suitcases needs to be counted. In the prior art, when the suitcases are conveyed to the designated position, they will fall off the conveying roller and reach the designated position in a falling manner. This will result in a messy pile of multiple suitcases, which is not only not conducive to the subsequent uniform handling of the suitcases, but also not convenient for counting the number of suitcases, thus affecting the efficiency of subsequent production and manufacturing; Therefore, in order to solve the above problem, this embodiment is used for a batch of square suitcases with the same specifications. First, according to the size of the suitcase, the electric push rod 32 is started to drive the hinge block 33 to rise and fall, and the hinge block 33 drives multiple connecting rods 34 to rotate simultaneously. The connecting rod 34 drives multiple limiting plates 9 to slide on the mounting plate 8 at the same time. The angle of the limiting plate 9 is regarded as a corner of the square, so that multiple limiting plates 9 can form a square with the same specifications as the suitcase. Then, the suitcase is placed on the roller conveyor assembly 41, and then the roller conveyor assembly 41 is used to convey the suitcase. When the suitcase is conveyed to the leftmost side frame 1, the suitcase will slide to the collection box 1 through the unloading plate 42. 1, at this time, the position of the suitcase in the collection box 11 is random, and then the motor 35 is started. When the connecting rod 2 31 and the gear 21 on one side rotate, the multiple connecting rods 2 31 and the gear 21 will rotate simultaneously under the action of the ring gear 17. When the angle between the connecting rod 1 26 and the connecting rod 2 31 changes, the slide plate 27 can slide on the slide bar 30, so that the multiple correction blocks 28 pass through the through slot 29 at the same time and approach the suitcase. When the multiple correction blocks 28 are all in contact with the side of the suitcase, the suitcase is corrected and is in the center of the collection box 11. At this time, the four corners of the suitcase are aligned with the four corners of the limit plate 9. Then the electric push rod 23 is started to drive the connecting rod 18 to rise, so that The hard tube 25 and the suction cup 24 pass through the through hole 20, and the suction cup 24 fits with the lower end surface of the suitcase, and then the vacuum pump 19 is used to evacuate the suction cup 24 to adsorb the suitcase, and then the multiple correction blocks 28 are driven away from the side of the suitcase again, and the electric push rod 23 continues to drive the suction cup 24 and the suitcase to rise. Since the lower side of the support block 37 is an inclined surface, when one corner of the suitcase contacts the support block 37, the support block 37 will slide on the limit plate 9 under the action of extrusion, and the slide column 38 will retract into the sleeve 39, and the spring 40 will be compressed until the end surface of one side of the support block 37 is flush with the end surface of one side of the limit plate 9. At this time, the suitcase continues to rise. When the lower end surface of the suitcase is higher than the support block 37, the support block 37 will slide on the limit plate 9. When the upper end surface of the support block 37 is in contact with the lower end surface of the suitcase, the support block 37 is reset under the action of the spring 40, so that the upper end surface of the support block 37 is in contact with the lower end surface of the suitcase to support the suitcase, and then the suction cup 24 is deflated to release the suitcase, and the suction cup 24 is reset, and then the above operation is repeated, and the suitcase can be squeezed by the subsequent suitcase to make the suitcases neatly stacked and placed, and the edges of the suitcases are aligned, and it is not easy to slip and tip over, thereby ensuring the neatness of the stacking of the suitcases, which is convenient for subsequent handling work. At the same time, since the suitcases are relatively neat, it is also convenient to count the number of suitcases, and the placement space can be adjusted according to the volume of the suitcases, and the adaptability is good; The box 11 is then pushed back to the right side of the collecting box 11, and the box 11 is then pushed back to the right side of the collecting box 11, so that the box 11 can be pushed back and placed flat in the collecting box 11. This can prevent the box 11 from being pushed back and placed flat in the collecting box 11, and prevent the box 11 from being pushed back and placed flat in the collecting box 11. Therefore, by utilizing the adjustable limiting mechanism and the correcting and lifting mechanism, the suitcases dropped from the roller conveying assembly 41 can be neatly stacked and placed, and the edges of the suitcases are aligned, making them not easy to slip or tip over, thereby ensuring the neatness of the stacking of the suitcases and facilitating subsequent handling work. Moreover, since the suitcases are relatively neat, it is also convenient to count their number, and the placement space can be adjusted according to the volume of the suitcases, with good adaptability. Moreover, when the suitcases fall into the collection box 11 through the unloading plate 42, the multiple knocking plates 15 move in turn to push the suitcases leaning against the frame of the collection box 11, so that they slide and lie flat in the collection box 11, thereby avoiding the situation where the suitcases cannot be corrected and lifted normally due to leaning against the edge of the collection box 11, thereby ensuring the smooth stacking of the suitcases.

[0024] In this embodiment, Figure 1 and Figure 11 As shown, the middle of the front and rear end surfaces of the side frame 1 are both rotatably provided with threaded rods 4, the threaded rods 4 are threadedly connected to the limit frame 2, the middle of the lower end of the limit frame 2 is slidably connected with a slide rod 5, and one end of the slide rod 5 is fixedly connected to the side frame 1; A plurality of rollers 3 are rotatably arranged on the limiting frame 2; Specifically, during the transportation of the suitcase, the roller 3 can be in contact with the surface of the suitcase to ensure that the suitcase always maintains the correct position and direction during the transportation process, and prevent the suitcase from shifting or tipping over during the transportation process. The roller 3 can roll and has a small friction with the suitcase, thereby ensuring smooth transportation. In addition, the threaded rod 4 can be manually rotated to move the limit frame 2, and the distance between the limit frames 2 on both sides can be adjusted to accommodate suitcases of different sizes.

[0025] Working principle: It is used for the same batch of square suitcases with the same specifications. First, according to the size of the suitcase, start the electric push rod three 32 to drive the articulated block 33 to lift. The articulated block 33 drives multiple link rods three 34 to rotate simultaneously. The link rods three 34 drive multiple limit plates 9 to slide on the mounting plate 8 at the same time. Regarding the included angle of the limit plates 9 as a corner of the square, multiple limit plates 9 can form a square with the same specifications as the suitcase. Then, place the suitcase on the roller conveying assembly 41, and then use the roller conveying assembly 41 to convey the suitcase. Moreover, during the conveying process of the suitcase, the correct position and direction of the suitcase can be ensured by the way that the roller 3 contacts the surface of the suitcase, preventing the suitcase from shifting or toppling during the conveying process. And the roller 3 can roll, with a small friction with the suitcase, ensuring the smoothness of the conveying. Also, the distance between the two limit frames 2 can be adjusted by manually rotating the threaded rod 4 to move the limit frame 2 to adapt to suitcases of different sizes. When the suitcase is conveyed to the leftmost side of the side frame 1, the suitcase will slide down to the collection box 11 through the blanking plate 42. At this time, the position of the suitcase in the collection box 11 is random. Then start the motor 35. When one side of the link rod two 31 and the gear 21 rotate, under the action of the gear ring 17, multiple link rods two 31 and the gear 21 will rotate simultaneously. When the included angle between the link rod one 26 and the link rod two 31 changes, the slide plate 27 can slide on the slide rod three 30, so that multiple correction blocks 28 pass through the through slots 29 and approach the suitcase at the same time. When multiple correction blocks 28 are all in contact with the side surface of the suitcase, the suitcase is corrected, and the suitcase is in the center position of the collection box 11, and at this time, the four corners of the suitcase are aligned with the four corners of the limit plates 9. Then start the electric push rod two 23 to drive the connecting rod 18 to rise, so that the hard tube 25 and the suction cup 24 pass through the through hole 20, and the suction cup 24 is in contact with the lower end surface of the suitcase. Then use the vacuum pump 19 to evacuate the air at the suction cup 24 to adsorb the suitcase. Then drive multiple correction blocks 28 away from the side surface of the suitcase again, and the electric push rod two 23 continues to drive the suction cup 24 and the suitcase to rise. Since the lower side of the support block 37 is an inclined surface, when a corner of the suitcase contacts the support block 37, under the extrusion effect, the support block 37 will slide on the limit plate 9, and the sliding column 38 will retract into the sleeve 39, and the spring 40 will be compressed until one end surface of the support block 37 is flush with one end surface of the limit plate 9. At this time, the suitcase continues to rise. When the lower end surface of the suitcase is higher than the upper end surface of the support block 37, the support block 37 will reset under the action of the spring 40, so that the upper end surface of the support block 37 is in contact with the lower end surface of the suitcase to support the suitcase. Then, by deflating the suction cup 24, the suction cup 24 will release the suitcase, and the suction cup 24 will reset. Then repeat the above operations, and the subsequent suitcases can squeeze the upper suitcase to stack the suitcases neatly, with the edges of the suitcases aligned, not easy to slip and topple, thus ensuring the neatness of the stacked suitcases, facilitating subsequent handling work, and the placement space can be adjusted according to the volume of the suitcase, with good adaptability;In order to prevent the suitcase from sliding out of the collection box 11 when it slides over the collection box 11 through the unloading plate 42, the collection box 11 is provided with a frame around it. When the suitcase falls into the collection box 11 through the unloading plate 42, the suitcase may lean against the frame of the collection box 11, resulting in the suitcase being unable to be corrected and lifted normally. Therefore, after the suitcase falls into the collection box 11, before the correction and lifting work, the four electric push rods 13 will be started in turn, so that the multiple push-down plates 15 move in turn until the push-down plates 15 completely cross the frame of the collection box 11, and then reset, so that the suitcase leaning against the frame of the collection box 11 can be pushed, so that it slides and lies flat in the collection box 11, which can avoid the suitcase leaning against the edge of the collection box 11 and being unable to be corrected normally. and lifting, ensuring the smooth stacking of suitcases; thus, the adjustable limit mechanism and the correction and lifting mechanism can be used to neatly stack the suitcases dropped from the roller conveyor assembly 41, and the edges of the suitcases are aligned, not easy to slip and tip over, ensuring the neatness of the stacking of the suitcases, facilitating the subsequent handling work, and the placement space can be adjusted according to the volume of the suitcases, with good adaptability, and when the suitcases fall into the collection box 11 through the unloading plate 42, the multiple push-down plates 15 move in turn, and the suitcases leaning against the frame of the collection box 11 can be pushed to slide and lie flat in the collection box 11, which can avoid the situation that the suitcases cannot be properly corrected and lifted due to leaning against the edge of the collection box 11, ensuring the smooth stacking of the suitcases. ;
