Description

Technical Field

[0001] This utility model relates to the field of packaging box palletizing technology, specifically a rapid box palletizing device. Background Technology

[0002] Palletizing boxes during packaging is a common practice, especially in large-scale production and logistics. Palletizing can effectively utilize space, improve stacking stability, and simplify the management and transportation of goods. It helps reduce transportation costs, improve work efficiency, and reduce the risk of damage.

[0003] There are two existing methods for palletizing packaging boxes: manual palletizing and automated mechanical palletizing. Mechanical palletizing uses robotic arms to lift the boxes. Current lifting methods are relatively simple, generally employing vacuum suction or gripping. Vacuum suction facilitates neat stacking of boxes, but it can cause them to fall off due to unstable suction (e.g., heavy boxes or uneven surfaces resulting in insufficient vacuum suction). While gripping provides a stable grip, the boxes are spaced further apart during stacking to allow the grippers to move in and out, preventing them from sticking together properly and hindering neat stacking, thus making transportation inconvenient. Utility Model Content

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a rapid box stacking device. This box stacking device can easily grasp the packaging boxes through a palletizing robot, ensuring the stability of the packaging box grasp and facilitating palletizing. At the same time, through the sensing device set in the inner wall of the protective fence, after the robot places the packaging box on the palletizing support plate, it drives the robot to push the packaging box towards the center of the palletizing support plate, so that the packaging boxes are tightly packed together, thereby achieving neat stacking of the packaging boxes.

[0005] This invention is achieved by constructing a rapid box-stacking device, including a palletizing robot, which is installed inside a protective barrier.

[0006] The feeding conveyor belt is installed on the feeding end of the guardrail;

[0007] The palletizing support plate is installed on the discharge end of the guardrail via a movable mechanism;

[0008] Several sensors are also installed on the inner wall of the guardrail to keep the palletizing robot arm neatly stacking the packaging boxes on the palletizing support pad.

[0009] Preferably, the feeding conveyor belt includes a support frame with an inclined top.

[0010] Two support plates are set opposite each other on the inclined surface at the top of the support frame;

[0011] Several feeding rollers are evenly spaced between two support plates and keep rotating;

[0012] The baffle is installed at the lowest end of the inclined surface of the support frame.

[0013] Preferably, the support plate has a groove at the top of one end near the baffle, and the groove is located between the gaps of the feeding rollers.

[0014] Preferably, the palletizing robot is provided with a clamping assembly at its movable end, the clamping assembly specifically including a mounting plate, and a connector for connecting to the palletizing robot is provided at the top center;

[0015] Two rotating rods are positioned opposite each other at both ends of the bottom of the mounting plate and are kept rotating.

[0016] Several rotating plates are fixed at their centers to the ends of rotating rods. One end of each rotating plate is hinged to a first driving device located on the top of a mounting plate. The other end of each rotating plate is provided with a connecting plate, on which several grippers are provided.

[0017] The second drive unit is mounted on the mounting plate and extends downward through the mounting plate while maintaining the bottom extension and retraction.

[0018] The pressure plate is located below the mounting plate and fixed to the bottom of the second drive unit.

[0019] Preferably, the gripper has an L-shaped cross-section. When the gripping assembly grips the packaging box on the feeding conveyor belt, the gripper inserts into the groove of the support plate and contacts the bottom of the packaging box.

[0020] Preferably, the active mechanism specifically includes two support frames, which are arranged opposite each other and keep their tops horizontal;

[0021] The plate is connected between two support frames;

[0022] The screw is rotatably mounted on the plate and maintains its length direction pointing towards the palletizing robot.

[0023] The support groove plate is mounted on the support frame and slides linearly by rotating a screw.

[0024] Preferably, the bottom of the support groove plate is provided with a sliding groove that is connected to the support frame and slides linearly. The bottom of the support groove plate is threaded through and threaded with the screw. The top of the support groove plate is provided with a limiting groove corresponding to the stacking support pad. The limiting groove is opened through the corresponding surface of the screw in the length direction. The screw is connected to a drive motor preset at the outer end of any plate body.

[0025] Preferably, the sensing device is disposed on the outer end of the support trough plate near the position of the palletizing robot and fixed to the inner wall of the guardrail. The sensing device is disposed opposite to the edge of the support trough plate.

[0026] Preferably, the sensing device at the discharge end of the guardrail is installed via a third driving device. One end of the third driving device is fixed to the guardrail, and the other end is set inside the guardrail to maintain extension and retraction and is connected to the sensing device. The third driving device is linked with the drive motor.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] This palletizing device utilizes a palletizing robot, greatly improving the ease of gripping packaging boxes and ensuring a stable and reliable gripping process. This effectively reduces palletizing errors caused by unstable gripping, improving overall work efficiency and quality. Simultaneously, with the help of sensors on the inner wall of the protective barrier, the robot can precisely guide the robot to place the packaging boxes on the palletizing support pad. Then, the robot pushes the packaging boxes towards the center of the support pad, ensuring a tight fit between the boxes and achieving neat stacking. This neat stacking method not only improves space utilization and facilitates storage and transportation but also reduces safety risks such as cargo tipping and collisions that may occur due to uneven stacking, ensuring the safety and integrity of the goods during the stacking process.

[0049] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of this utility model and are not intended to limit this utility model in any way. The accompanying drawings in this utility model are only for illustrative purposes and to facilitate understanding of the embodiments and are not intended to limit this utility model in any way.

[0050] It should be noted that the structures, proportions, sizes, etc. shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0051] As described in the background section, when existing palletizing robots use vacuum adsorption to grip packaging boxes, the grip may be unstable due to the large weight of the packaging boxes or the uneven surface of the packaging boxes, resulting in them falling off. When using clamping, there are gaps between the palletized packaging boxes in order to facilitate the entry and exit of the grippers, which affects the neat stacking of the packaging boxes and also affects transportation.

[0052] Based on the above reasons, in order to solve the above problems, this utility model provides the following technical solution:

[0053] Example 1,

[0054] Please see the appendix Figure 1 ~Appendix Figure 4 This utility model provides a rapid box stacking device, including a palletizing robot 4, which is set inside the protective fence 1;

[0055] Feed conveyor belt 2 is installed on the feed end of guardrail 1;

[0056] The palletizing support plate 8 is installed on the discharge end of the guardrail 1 via the movable mechanism 3;

[0057] Several sensing devices 5 are also installed on the inner wall of the protective railing 1. The sensing devices 5 are used to keep the palletizing robot 4 neatly stacking the packaging boxes 7 on the palletizing support pad 8.

[0058] To prevent the palletizing robot from colliding with the sensing device during palletizing, in this embodiment, the sensing device 5 is disposed on the outer end of the support groove plate 304 near the position of the palletizing robot 4 and fixed to the inner wall of the guardrail 1. The sensing device 5 is disposed opposite to and corresponds to the edge of the support groove plate 304.

[0059] Furthermore, the sensing device can be configured as an infrared sensing device, with one end as the transmitting end and the opposite end as the receiving end. When the transmitting end and the receiving end are blocked by the packaging box 7, the palletizing robot 4 is driven to push the packaging box 7 towards the center of the palletizing support plate 8 until the transmitting end and the receiving end are connected.

[0060] When the palletizing device is used, it first places the palletizing support plate 8 on the movable mechanism 3. At the same time, the movable mechanism 3 moves the palletizing support plate 8 to a position close to the palletizing robot 4 and fixes it. Then, the palletizing robot 4 moves to pick up the packaging box 7 on the feeding conveyor belt 2 and moves it to the designated position on the palletizing support plate 8 before releasing it. The sensing device 5 detects whether the packaging box 7 on the palletizing support plate 8 is at the edge. If so, the packaging box 7 will block the sensing signal of the sensing device 5. Then, the blocked sensing signal drives the palletizing robot 4 to push the packaging box 7 towards the center of the palletizing support plate 8 until the sensing signal of the sensing device 5 is no longer blocked. The above steps are repeated to achieve palletizing by the palletizing robot 4 picking up and placing the packaging box 7.

[0061] Example 2,

[0062] Please see the appendix Figure 8 Based on Embodiment 1, in order to facilitate the automatic conveying of the packaging box 7 and make it easier for the palletizing robot to grasp it, the feeding conveyor belt 2 includes a support frame 201 with an inclined top.

[0063] Two support plates 202 are arranged opposite each other on the inclined surface at the top of the support frame 201;

[0064] Several feeding rollers 203 are evenly spaced between two support plates 202 and keep rotating;

[0065] The baffle 204 is located at the lowest end of the inclined surface of the support frame 201.

[0066] In this embodiment, a groove 205 is provided on the top of one end of the support plate 202 near the baffle 204, and the groove 205 is located between the gaps of the feeding rollers 203.

[0067] Example 3,

[0068] Please see the appendix Figure 7 Appendix Figure 9 and attached Figure 10 Based on Embodiment 2, in order to facilitate the gripping of the packaging box and ensure the stability of the gripping of the packaging box, a gripping component 9 is provided on the active end of the palletizing robot 4. The gripping component 9 specifically includes a mounting plate 902, and a connector 901 connected to the palletizing robot 4 is provided at the top center.

[0069] Two rotating rods 905 are positioned opposite each other at both ends of the bottom of the mounting plate 902 and are kept rotating.

[0070] Several rotating plates 904 are fixed at their centers to the ends of rotating rods 905. One end of the rotating plate 904 is hinged to the first driving device 903 located on the top of the mounting plate 902. The other end of the rotating plate 904 is provided with a connecting plate 906, and several grippers 907 are provided on the connecting plate 906.

[0071] The second drive device 908 is mounted on the mounting plate 902 and extends downward through the mounting plate 902 at its bottom.

[0072] The pressure plate 909 is located below the mounting plate 902 and fixed to the bottom of the second drive device 908.

[0073] To prevent the packaging box from deforming when gripping it, in this embodiment, the gripper 907 has an L-shaped cross-section. When the gripping assembly 9 grips the packaging box 7 on the feeding conveyor belt 2, the gripper 907 inserts into the groove 205 of the support plate 202 and contacts the bottom of the packaging box 7.

[0074] Example 4,

[0075] Please see the appendix Figure 5 Based on Embodiment 1, in order to facilitate the placement of the palletizing support pad and its movement to the working position of the palletizing robot for palletizing, and to facilitate the removal of the palletizing support pad by an external forklift after palletizing, the active mechanism 3 specifically includes two support frames 301, which are arranged opposite each other and keep the top horizontal.

[0076] The plate 302 is connected between two support frames 301;

[0077] The screw 303 is rotatably mounted on the plate 302 and maintains its length direction pointing towards the palletizing robot 4;

[0078] The support groove plate 304 is mounted on the support frame 301 and slides linearly by rotating the screw 303.

[0079] To prevent the palletizing support plate from moving on the support groove when pushing the packaging box on the palletizing support plate, in this embodiment, the bottom of the support groove plate 304 is provided with a sliding groove 3042 that is connected to the support frame 301 and slides linearly. The bottom of the support groove plate 304 is threaded through and connected to the screw 303. The top of the support groove plate 304 is provided with a limiting groove 3041 corresponding to the palletizing support plate 8. The limiting groove 3041 is opened through the corresponding surface of the screw 303 in the length direction. The screw 303 is connected to a drive motor that is preset at the outer end of any plate 302.

[0080] To prevent the external forklift from contacting the sensing device when removing the palletized support pad, the sensing device 5 at the discharge end of the guardrail 1 is installed via a third drive device 6. One end of the third drive device 6 is fixed to the guardrail 1, and the other end is set inside the guardrail 1 to maintain extension and retraction and is connected to the sensing device 5. The third drive device 6 is linked with the drive motor.

[0081] When the drive motor runs, it moves the palletizing support plate 8 away from the palletizing robot, indicating that palletizing is complete. The third drive device 6 retracts, moving the sensing device 5 towards the guardrail to prevent collisions between the palletizing support plate 8 and the sensing device 5 when the forklift picks up or places the palletizing support plate 8. When the drive motor runs and moves the palletizing support plate 8 closer to the palletizing robot, the palletizing support plate 8 is fixed and the drive motor stops. At this time, the third drive device 6 extends, moving the sensing device 5 to align with the opposite sensing device, thus enabling normal operation and facilitating palletizing.

[0082] The drive units in this racking device can all be configured as cylinders, electric cylinders, etc., which are easy to extend and retract linearly and are easy to control automatically.

[0083] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
