Description

Technical Field

[0001] This application relates to the field of palletizing machine technology, and more specifically, to an easily adjustable box palletizing machine. Background Technology

[0002] A palletizer is a mechanical device used to automate the stacking and stacking of goods (such as boxes, bags, pallets, etc.). It is widely used in warehousing, logistics, food, chemical, and manufacturing industries.

[0003] Patent CN207375362U discloses an easily adjustable box palletizing machine. This patent uses a combination of a bracket and a slide rail. The bracket can be adjusted according to the height of the box fed into the conveyor belt. The bracket can be easily installed and fixed using a mounting base, making the installation position of the palletizing machine unrestricted. This allows for adjustment of the position of the second electric telescopic rod fixed to one side of the mounting block. By energizing the third electric telescopic rod, the crossbeam slidably connected to the surface of the slide rail can be easily adjusted, thereby facilitating the adjustment of the robotic arm connected to the bottom of the second electric telescopic rod via a threaded seat.

[0004] Although the patent allows the robotic arm to clamp and stack the boxes, it does not protect the bottom of the workpiece during the clamping and transfer process. In case of an accident, such as when the robotic arm malfunctions and the clamping force is insufficient, the workpiece will fall directly to the ground and cause damage. Utility Model Content

[0005] To address the aforementioned issues, this application provides an easily adjustable box palletizing machine.

[0006] The adjustable box palletizing machine provided in this application adopts the following technical solution:

[0008] A blocking mechanism for supporting the box is provided inside the lower part of the clamping cover;

[0009] The blocking mechanism includes a pair of rotatable support members, each of which is connected to two telescopic electric push rods. The output ends of the two electric push rods are connected to a receiving plate for contacting the bottom of the box.

[0010] The inside of the clamping cover is also equipped with a height sensor for detecting the height of the goods.

[0011] Through the above technical solution, the supporting components and receiving plates in the blocking mechanism can directly support the bottom of the box, preventing the box from falling directly to the ground after losing its fixation, thereby reducing the damage to the box caused by falling and reducing material loss costs. Secondly, the blocking mechanism can work with the electric push rod to drive the receiving plate to extend and retract, which can adapt to boxes of different heights, ensure stable support for the bottom of the box, and improve the adaptability of the equipment to boxes of different specifications.

[0012] Furthermore, motors are installed on both sides of the clamping cover, and the output end of the motors is fixedly connected to a rotating shaft.

[0013] Furthermore, the outer walls of both shafts are fixedly connected to the support components.

[0014] Furthermore, the inner top of the clamping cover is provided with a connecting shell, and the bottom of the connecting shell is connected to multiple vacuum suction cups.

[0015] Furthermore, each vacuum suction cup is equipped with a one-way valve inside to prevent gas backflow, and the top of the clamping cover is equipped with an air pump to provide negative pressure to the vacuum suction cup.

[0016] Furthermore, the air pump is connected to the connecting shell via an airflow pipe.

[0017] Furthermore, both ends of the frame are equipped with front-to-back sliding rails, and the inner sides of the two front-to-back sliding rails are equipped with left-to-right sliding rails. The two ends of the left-to-right sliding rails are slidably engaged with the front-to-back sliding rails through sliders.

[0018] Furthermore, an electric telescopic plate is slidably connected to the outer wall of the left and right moving slide rails, and the bottom of the electric telescopic plate is connected to the clamping cover by bolts.

Detailed Implementation

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Reference Figures 1-5 An easily adjustable box palletizer includes a frame 1 and a clamping cover 5 disposed inside the frame 1.

[0029] A blocking mechanism for supporting the box is provided inside the lower part of the clamping cover 5;

[0030] The blocking mechanism includes a pair of rotatable support members 12, and two telescopic electric push rods 13 are connected above each support member 12. The output ends of the two electric push rods 13 are connected to a receiving plate 14 for contacting the bottom of the box.

[0031] The inside of the clamping cover 5 is also equipped with a height sensor 11 for detecting the height of the cargo.

[0032] When clamping the box, when the multiple vacuum suction cups 7 at the bottom of the inner top connecting shell 6 gently contact the top surface of the box, the air pump 8 at the top of the clamping cover 5 starts, and the air is quickly extracted from the connecting shell 6 and the vacuum suction cups 7 through the airflow pipe 9. The negative pressure makes the vacuum suction cups 7 tightly adhere to the top surface of the box. At the same time as the vacuum adsorption, the motors 15 on both sides of the clamping cover 5 synchronously drive the rotating shaft to rotate, which drives a pair of support members 12 in the blocking mechanism to rotate relative to each other to a horizontal position below the box. At this time, the height sensor 11 will monitor the distance between the bottom of the box and the support member 12 in real time and transmit the distance data to the external control system. The required extension of the electric push rod 13 is calculated based on the box height data to ensure that the receiving plate 14 can contact the bottom of the box, forming a double fixation in cooperation with the top vacuum suction cup 7.

[0033] Reference Figures 3-5Motors 15 are provided on both sides of the clamping cover 5. The output end of the motor 15 is fixedly connected to a rotating shaft. The outer walls of the two rotating shafts are fixedly connected to the support member 12. A connecting shell 6 is provided on the inner top of the clamping cover 5. Multiple vacuum suction cups 7 are connected to the bottom of the connecting shell 6. Each vacuum suction cup 7 is provided with a one-way valve 10 to prevent gas backflow. An air pump 8 is provided on the top of the clamping cover 5 to provide negative pressure to the vacuum suction cups 7. The air pump 8 is connected to the connecting shell 6 through an airflow pipe 9.

[0034] This application employs an external control system to control the palletizer for palletizing. The external control system (typically a PLC control system, coupled with a human-machine interface and sensor signal modules) governs the entire palletizing process through a closed-loop logic of preset programs and real-time signal feedback. First, the operator inputs parameters such as the box size, number of palletizing layers, and workstation coordinates into the human-machine interface. After receiving the "box in position signal" from the production line, the system drives the left-right sliding rail 3 to slide along the front-back sliding rail 2, and the electric telescopic plate 4 to slide along the left-right sliding rail 3. Combined with encoder feedback to correct the position, the clamping cover 5 is positioned directly above the box. Simultaneously, the height sensor 11 transmits distance data in real time. After positioning, the system controls the electric telescopic plate 4 to move downwards in stages according to the data from the height sensor 11. Once the vacuum suction cup 7 contacts the box, the air pump 8 is activated, and the external air pressure sensor (existing technology) is activated. (Not shown in the diagram) Monitor negative pressure, maintain pressure after reaching the target, and simultaneously send a command to motor 15 to rotate support 12 to a horizontal position. Then, based on the distance between the bottom of the box and support 12 detected by height sensor 11, control electric push rod 13 to extend until support plate 14 contacts the box, completing double fixation. Subsequently, the system plans the transfer path and coordinates the slide rail and electric telescopic plate 4 to transfer smoothly. After reaching the stacking station, the system controls electric telescopic plate 4 to move down to a distance between the box and the stacking surface according to the number of layers and box height. Then, control electric push rod 13 to retract, support 12 to rotate to the open state, and open air pump 8 to release pressure. After the box is placed stably, drive motor 15 to reset support 12 and electric telescopic plate 4 to move up clamping cover 5. Finally, the system counts the number of stacks. If the preset number is not reached, it returns to the positioning stage for a cycle. After reaching the target, all mechanisms reset and send a completion signal to the production line.

[0035] Reference Figures 1-2 Both ends of the frame 1 are provided with front and rear moving slide rails 2. The inner sides of the two front and rear moving slide rails 2 are provided with left and right moving slide rails 3. The two ends of the left and right moving slide rails 3 are slidably engaged with the front and rear moving slide rails 2 through sliders. The outer wall of the left and right moving slide rails 3 is slidably connected with an electric telescopic plate 4. The bottom of the electric telescopic plate 4 is connected to the clamping cover 5 by bolts.

[0036] First, based on the initial position of the box to be stacked, the clamping cover 5, which is bolted to the bottom of the electric telescopic plate 4, is moved to the top of the box by the cooperation of the front-to-back moving slide rail 2 and the left-to-right moving slide rail 3 at both ends of the frame 1 (the sliders at both ends of the left-to-right moving slide rail 3 slide along the front-to-back moving slide rail 2 to adjust the front-to-back direction, and the electric telescopic plate 4 slides along the outer wall of the left-to-right moving slide rail 3 to adjust the left-to-right direction). Then, the control system drives the electric telescopic plate 4 to slowly extend, causing the clamping cover 5 to move vertically downward to clamp the goods.

[0037] Working principle: The operator inputs the dimensions of the box to be palletized, the number of palletizing layers, and the coordinates of the palletizing station through the human-machine interface of the external PLC control system. The system simultaneously detects the status of components such as air pump 8, motor 15, and electric push rod 13. After confirming that there are no abnormalities, it receives the "box in position signal" from the production line.

[0038] Next, the positioning stage begins. The system drives the sliders on the front and rear sliding rails 2 at both ends of the frame 1 to slide the left and right sliding rails 3 in the front and rear direction. At the same time, it controls the electric telescopic plate 4 to slide along the outer wall of the left and right sliding rails 3. Combined with the position signal feedback from the encoder, the deviation is corrected, and the clamping cover 5, which is bolted to the bottom of the electric telescopic plate 4, is moved to the top of the box. After positioning is completed, the box gripping stage begins. The electric telescopic plate 4 is driven to extend slowly in stages, which drives the clamping cover 5 to move vertically downward until the vacuum suction cup 7 at the bottom of the inner top connecting shell 6 contacts the top surface of the box. Then, the air pump 8 is started, and the air in the connecting shell 6 and vacuum suction cup 7 is extracted through the airflow pipe 9. After the external air pressure sensor detects that the negative pressure value reaches the standard, the system controls the air pump 8 to maintain the pressure. At the same time, the one-way valve 10 of the air path prevents the gas from flowing back. Simultaneously, the motors 15 on both sides of the clamping cover 5 drive the rotating shaft to rotate, which drives the support 12 to rotate relative to the bottom of the box to a horizontal position. The height sensor 11 detects the distance between the bottom of the box and the support 12. Based on this, the system controls the electric push rod 13 to extend, pushing the receiving plate 14 to move up to contact the bottom of the box, forming a double fixation.

[0039] Then, the box is transferred. The system plans the transfer path and coordinates the front and rear moving slide rails 2, left and right moving slide rails 3 and electric telescopic plate 4 to smoothly transfer the clamping cover 5 and the box to the top of the stacking station. During this period, the negative pressure value and the contact status of the receiving plate 14 are monitored in real time. If there is an abnormality, the system stops.

[0040] Upon arrival at the workstation, the system, based on the number of palletizing layers and the height of the box, controls the electric telescopic plate 4 to move down until there is a certain gap between the bottom of the box and the stacking surface. Then, it controls the electric push rod 13 to retract, and the motor 15 to drive the support component 12 to rotate and open. Next, the air pump 8's pressure relief valve is opened to release pressure, allowing the box to be placed stably. After placement, the electric telescopic plate 4 retracts, causing the clamping cover 5 to move upwards, and the motor 15 drives the support component 12 to reset. Finally, the system counts the number of pallets. If the preset value is not reached, it returns to the positioning stage for a loop. Once the target is reached, all mechanisms reset and a completion signal is sent to the production line, completing one palletizing cycle.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
