[0002] After the fertilizer is packaged in bags, it needs to be moved to the pallet by a robotic arm for palletizing. Before palletizing, although the bagged fertilizer is shaped by a square shaping roller, the thickness in the middle of the bagged fertilizer is still thicker than the thickness at both ends. Therefore, when palletizing, especially when stacking at high height (stacking height exceeds 2 meters), the bagged fertilizer after palletizing tends to tilt outward and has poor stability. When the forklift is used for transfer transportation, the bagged fertilizer is prone to slipping, posing a greater safety risk. Utility Model Content

[0024] Motor reducer 40 , vibrator 50 , base 60 , mounting foot plate 61 , bagged fertilizer 70 . DETAILED DESCRIPTION

[0025] like Figure 1-3 As shown, a fertilizer packaging high stacking shaping device includes a conveyor roller frame 10, on which a plurality of rollers 20 are rotatably mounted, a transmission wheel 21 is mounted at one end of the roller 20, and the transmission wheels 21 of adjacent rollers 20 are connected for transmission via a first transmission structure 22. A motor reducer 40 is also mounted on the conveyor roller frame 10, and the output shaft of the motor reducer 40 is transmission-connected to one of the transmission wheels 21. The rollers 20 are arranged in sequence in a manner of being high in the middle and low on both sides. The conveyor roller frame 10 is mounted on a base 60 via an elastic element 30, and a vibrator 50 is also mounted on the conveyor roller frame 10. The rollers 20 on the conveyor roller frame 10 are connected to each other via the first transmission structure 22, and then driven by the motor reducer 40 to rotate the rollers 20, so that the bagged fertilizer 70 can be conveyed to the conveyor roller frame 10, see Figure 3 At this time, the motor reducer 40 stops running, and the vibrator 50 starts for 2 to 3 seconds. Since the rollers 20 are arranged in a way that the middle is high and the two sides are low, the bagged fertilizer 70 is shaped to a shape where the middle thickness is equal to or less than the thickness at both ends, and then the bagged fertilizer 70 is moved to the pallet for stacking by the robot arm. In this way, when performing high stacking, the bagged fertilizer is not easy to tilt or slide outward after stacking, and the stability is better, which reduces the safety risk of forklift transfer.

[0026] When in use, the base 60 is fixed to the ground concrete foundation bolts through the mounting foot plate 61 at the bottom.

[0027] Preferably, the vibrator 50 adopts a vibration motor of model YZO17-4.

[0028] In one embodiment, the elastic element 30 is a spring. In this case, a connecting shaft can be welded to each of the four corners of the lower side of the conveyor roller frame 10, and four connecting shafts can be fixedly welded to the corresponding positions on the upper end of the base 60, and the two ends of the four springs are respectively fitted to the two corresponding connecting shafts above and below, so that the conveyor roller frame 10 can be installed on the base 60 through the spring.

[0029] In another embodiment, see Figure 1 A guide rod 31 is installed on the base 60, and a longitudinal hole is provided on the lower cross bar 12. The guide rod 31 moves upward through the hole on the lower cross bar 12. The spring is sleeved on the guide rod 31 and is located between the conveyor roller frame 10 and the base 60. Through the above structure, the conveyor roller frame 10 can vibrate up and down along the guide rod 31, so that the front, back, left and right positions of the conveyor roller frame 10 will not change, which is convenient for the robot arm to locate and grasp.

[0030] Further, a guide sleeve 33 is installed on the lower cross bar 12, and the guide rod 31 passes through the guide sleeve 33. The guide rod 31 is slidably connected with the guide sleeve 33. The guide sleeve 33 is used as a wearing part. When the guide sleeve 33 is worn, the guide sleeve 33 can be replaced.

[0031] Furthermore, a limit plate 32 is installed on the top of the guide rod 31. The limit plate 32 has a hole in the middle and is installed on the top of the guide rod 31 by screws. The limit plate 32 limits the conveyor roller frame 10 to prevent the conveyor roller frame 10 from falling off the guide rod 31. Of course, if Figure 1 As shown, the limiting plate 32 is higher than the lower cross bar 12 by a certain distance.

[0032] It should be noted that, since a bag of bagged fertilizer weighs 50 kg, this weight is pressed on the conveyor roller frame 10, so that the conveyor roller frame 10 does not bounce violently, so it is only necessary to install a spring on the guide rod 31 between the conveyor roller frame 10 and the base 60. Of course, according to actual needs, a spring can also be installed on the guide rod 31 between the limit plate 32 and the guide sleeve 33.

[0033] In another embodiment, the elastic element 30 is a rubber shock-absorbing pad, and the upper and lower ends of the rubber shock-absorbing pad are respectively connected and fixed to the conveyor roller frame 10 and the base 60.

[0034] The rubber shock-absorbing pad is an existing technology, for example, a rubber shock-absorbing pad produced by Shandong Honghao Electromechanical Equipment Manufacturing Co., Ltd. The rubber shock-absorbing pad has two metal mounting plates, and an elastic rubber column is arranged between the two mounting plates. The rubber column and the two mounting plates are an integrated structure. During installation, the two mounting plates are respectively connected and fixed to the conveyor roller frame 10 and the base 60 by bolts.

[0035] When in use, the rubber shock-absorbing pad supports the weight of the conveyor roller frame 10 and the bagged fertilizer 70, and when the vibrator 50 is started, the conveyor roller frame 10 vibrates.

[0036] See also Figure 1 The conveying roller frame 10 is provided with a baffle 14 at the downstream side of the roller 20. The baffle 14 is provided to prevent the bagged fertilizer 70 from falling due to the failure of the detection switch.

[0037] In order to facilitate the robot arm to grab, the conveyor roller frame 10 is provided with upwardly extending supports 11 at both ends of the roller 20, and the supports 11 are installed with bearing seats 13, and the central axes at both ends of the roller 20 are respectively connected to the bearing seats 13 on both sides. In this way, a gap is formed between the supports to facilitate the clamp on the robot arm to enter the two rollers 20. Since the first transmission structure 22 is installed at one end of the roller 20, the clamp of the robot arm should be as far away from the side of the first transmission structure 22 as possible when in use.

[0038] Specifically, the transmission wheel 21 is a double-groove pulley, and the first transmission structure 22 is a belt. Specifically, depending on the shape of the grooves of the double-groove pulley, the belt can be an O-belt or a V-belt.

[0039] In addition, the transmission wheel 21 may also be a double-row sprocket, and then the first transmission structure 22 is a chain.

[0040] Specifically, a pulley or a sprocket is installed on the output shaft of the motor reducer 40, the pulley is connected to the double-groove pulley through a belt, and the sprocket is connected to the double-row sprocket through a chain.

[0041] The action process or principle of the utility model is as follows:

[0042] See also Figure 3 When in use, the motor reducer 40 is started, and the bagged fertilizer 70 transported from the square shaping roller enters the roller 20 on the conveying roller frame 10. Since the laser beam switch is installed on both sides of the conveying roller frame 10 near the baffle 14, when the bagged fertilizer 70 runs to the position shown in the figure, the bagged fertilizer 70 blocks the light beam of the laser beam switch. At this time, the motor reducer 40 stops, and then the vibrator 50 is started for 2 to 3 seconds to vibrate the bagged fertilizer 70. Since the roller 20 is arranged in a manner of high in the middle and low on both sides, the bagged fertilizer 70 is shaped to a middle thickness equal to or less than the thickness at both ends. The bagged fertilizer after palletizing is not easy to tilt or slide outward, and then the bagged fertilizer 70 on the conveying roller frame 10 is moved to the pallet by the mechanical arm for palletizing.

[0043] After the bagged fertilizer 70 is moved away, the light beam of the laser beam switch is not blocked, and the motor reducer 40 starts to operate to transport the next bagged fertilizer 70 to the conveying roller frame 10.
