Description

Technical Field

[0001] The invention belongs to the technical field of palletizing equipment, and in particular relates to a fast palletizing equipment for packaging boxes. Background Art

[0002] Packing box palletizing equipment is a device used to stack and place packing boxes according to certain rules and sequences. Stacking the boxes neatly can more effectively utilize the space in the warehouse or storage area, increase storage capacity, and reduce storage costs. The stacked boxes are arranged in an orderly manner, which is convenient for inventory management and quantity statistics, and is conducive to accurately grasping the storage situation of goods.

[0003] At present, the stacking height of packaging boxes is mostly selected according to the storage space. However, when the supporting strength of the packaging boxes is low and the items placed in the packaging boxes are heavy, the relatively high stacking height will make the packaging boxes in the lower layer unable to withstand the pressure of the upper layer of goods, which will lead to the collapse of the overall stacking structure and cause the goods to fall and be damaged. The collapsed packaging boxes will injure nearby workers, posing a major safety hazard. At present, there is a lack of stacking technology that determines the stacking height based on the supporting strength of the packaging boxes and the weight of the goods, resulting in a high stacking height that is prone to collapse, and a low stacking height that causes a waste of storage space, affecting the stable progress of the actual stacking work.

[0038] A PLC controller 11 is fixedly installed on the upper end of the mobile base 1, and the PLC controller 11 is electrically connected to the handling and transfer mechanism 2, the bottom support mechanism 3, the weighing feedback mechanism 4, the pressurization detection mechanism 5, the support strength feedback mechanism 6, the box height feedback mechanism 7, the stacking height adjustment mechanism 8 and the stacking in place confirmation mechanism 9 respectively.

[0039] The operating principle of the present invention is described as follows: the entire device is moved to the position to be stacked by the mobile base 1, and the packaging box to be stacked is transferred by the belt conveyor 10. When the packaging box moves between the two clamping plates 211, the PLC controller 11 controls the belt conveyor 10 to stop, and the PLC controller 11 controls the double-axis motor 29 to operate, and the double-axis motor 29 drives the adjusting screw 210 to rotate. The two clamping plates 211 are brought close to each other through the threaded sleeve effect of the adjusting screw 210 and the clamping plate 211, so that the packaging box is firmly clamped and fixed. The controller 11 then controls the driving motor 25 to move, and the driving motor 25 drives the rotating screw 24 to rotate. Through the threaded sleeve effect of the rotating screw 24 and the lifting block 26, the lifting block 26 cooperates with the lifting plate 27 to lift the packaging box to a certain height. The PLC controller 11 then controls the rotating motor 21 to move, and the rotating motor 21 drives the rotating plate 22 to rotate, thereby moving the packaging box to the side, so that the packaging box is transferred to the stacking position. The PLC controller 11 then controls the double-axis motor 29 to reverse, so that the clamping plate 211 releases the clamping fixation of the packaging box, and the stacking work of the packaging box is realized;

[0040] Before palletizing, the packaging box is placed on the bottom support plate 32, and the PLC controller 11 controls the electric push rod 35 to move. The electric push rod 35 pushes the support plate 36 to move up and support the lower end of the bottom support plate 32 to achieve the limit locking of the bottom support plate 32. The PLC controller 11 then controls the electric telescopic rod 52 to move. The electric telescopic rod 52 pushes the pressure plate 53 to gradually move downward. The pressure plate 53 achieves a stable downward pressure on the detection plate 54 through the action of the guide slide bar 55 and the pressure spring 56. When the detection plate 54 contacts the upper side of the packaging box, the detection plate 54 is relatively fixed. As the pressure plate 53 continues to be pressed downward, the pressure plate 53 moves toward the detection plate 54, and then the pressure spring 56 is squeezed, so that the pressure spring 56 exerts a pressure on the detection plate 54. The plate 54 provides a greater squeezing force until damage to the packaging box is manually observed. At this time, the electric telescopic rod 52 is controlled by the PLC controller 11 to stop the action. When the structural strength of the packaging box is higher, the packaging box can withstand a greater pressure, which makes the pressure plate 53 move toward the detection plate 54. In the process of the pressure plate 53 moving toward the detection plate 54, the guide slide bar 55 acts in the opposite direction on the feedback plate 63, so that the feedback plate 63 drives the strength conductive contact 64 to slide on the strength resistance rod 65 along the first friction resistance rod 62. The greater the distance, the smaller the access resistance of the strength resistance rod 65, and the strength conductive contact 64 and the strength resistance rod 65 are connected in series in the power supply circuit of the second thrust electromagnetic plate 811. The second thrust electromagnetic plate 811 is powered on, thereby increasing the power supply current of the second thrust electromagnetic plate 811, and the magnetism of the second thrust electromagnetic plate 811 is stronger. The second thrust electromagnetic plate 811 is powered on to generate the same magnetism as the second thrust permanent magnet plate 810, thereby increasing the distance that the strength control plate 88 slides along the fourth friction resistance rod 87, thereby increasing the sliding distance of the control conductive contact 89 on the control resistor rod 84, and decreasing the access resistance of the control resistor rod 84. The control conductive contact 89 and the control resistor rod 84 are connected in series to the power supply circuit of the push electromagnetic plate 95, thereby increasing the magnetism of the push electromagnetic plate 95, and increasing the sliding distance of the moving plate 93 along the fifth friction resistance rod 92 in cooperation with the push permanent magnet plate 94. , the larger the distance between the confirmation switch 96 and the confirmation plate 99, before stacking each packaging box, the PLC controller 11 first controls the servo motor 98 to work for 5s, and the servo motor 98 drives the transfer screw 97 to rotate for 5s. Through the threaded sleeve effect of the transfer screw 97 and the confirmation plate 99, the confirmation plate 99 moves a fixed distance in the confirmation shell 91 until the estimated stacking height is reached. When the confirmation plate 99 acts on the confirmation switch 96, the PLC controller 11 controls to stop the next packaging box from continuing to stack upwards. Based on the supporting strength of the packaging box, the final feasible stacking height can be confirmed. Under the premise of ensuring safe and stable stacking, the storage space utilization rate is improved as much as possible to save costs;

[0041] After the support strength of the packaging box is tested, the PLC controller 11 controls the electric push rod 35 to drive the support plate 36 to move downward, so that the support plate 36 releases the limit support on the bottom support plate 32, and under the action of the gravity of the packaging box, the bottom support plate 32 moves downward along the anti-slip rod 31 to overcome the elastic force of the push spring 34. Specifically, the greater the weight of the packaging box, the greater the distance the bottom support plate 32 moves downward to overcome the push spring 34, and thus the greater the distance the transmission rack 47 moves downward, and the transmission screw 42 is driven to rotate through the meshing action of the transmission rack 47 and the transmission gear 46, and then the threaded sleeve action of the transmission screw 42 and the transmission seat 43 makes the weighing conductive contact 44 slide on the weighing resistor rod 45. The larger the distance, the smaller the access resistance of the weighing resistor rod 45, and the weighing conductive contact 44 and the weighing resistor rod 45 are connected. 5 is connected in series to the power supply circuit of the first thrust electromagnetic plate 86, thereby making the magnetism of the first thrust electromagnetic plate 86 stronger, the first thrust electromagnetic plate 86 cooperates with the first thrust permanent magnet plate 85 to drive the weighing control plate 83 to slide along the third friction resistance rod 82. The greater the distance that the control resistor rod 84 moves forward, the shorter the sliding distance between the control resistor rod 84 and the control conductive contact piece 89, and the greater the access resistance value of the control resistor rod 84, the weaker the magnetism of the squeezing and pushing electromagnetic plate 95, the smaller the distance between the confirmation switch 96 and the confirmation plate 99, and the lower the estimated stacking height. The final feasible stacking height can be confirmed based on the weight of the items placed in the packaging box, and the storage space utilization rate can be improved as much as possible to save costs while ensuring the safety and stability of the stacking.

[0042] It is additionally noted that after the supporting strength and weighing test of the packaging box, after the final positions of the regulating conductive contact piece 89 and the regulating resistor rod 84 are confirmed, the PLC controller 11 controls the power supply device to supply power to the squeezing electromagnetic plate 95, so that the confirmation switch 96 moves to the final confirmation position, thereby confirming the final stacking height;

[0043] As the electric telescopic rod 52 pushes the detection plate 54 downward, the force-adding rod 78 on one side of the detection plate 54 acts on the force-bearing plate 77, causing the force-bearing plate 77 to move downward synchronously along the second friction resistance rod 76 until the detection plate 54 moves to the uppermost end of the packaging box and stops moving. At this time, the force-bearing plate 77 also stops moving downward synchronously. Specifically, the higher the height of the packaging box, the smaller the downward movement distance of the force-bearing plate 77, thereby making the distance between the two trigger switches 79 larger. When stacking, the PLC controller 11 controls the drive motor 25 to drive the packaging box to lift the packaging box, first making the packaging box move up 10 cm, and then the PLC controller 11 controls the forward and reverse motor 73 to rotate forward, and the forward and reverse motor 73 drives the forward and reverse screw 72 to rotate forward, and the trigger plate 74 is threadedly connected with the forward and reverse screw 72 to make the trigger plate 74 move forward. The palletizing operation is then continued until the trigger plate 74 is pressed against the trigger switch 79, which means that the height of the box to be palletized is equal to the height of the box. This satisfies the stacking requirement and enables stable palletizing. At this time, the PLC controller 11 connects the forward and reverse motors 73 to the reverse drive circuit, so that the next action of the forward and reverse motors 73 is reverse drive. In the stacking of the next box, the trigger plate 74 triggers the trigger switch 79 twice before the PLC controller 11 controls the drive motor 25 and the forward and reverse motor 73 to stop. As the number of palletizing boxes increases, the number of times the trigger switch 79 is pressed and triggered also increases. This allows for rapid detection of the height of the boxes to be palletized and automatic adjustment of the stacking interval height based on the height of the boxes, so that the boxes can be stably stacked together.
