Description

Technical Field

[0001] This utility model relates to the field of palletizing machine technology, specifically a palletizing and packaging machine for recycled permeable paving bricks. Background Technology

[0002] With the acceleration of urbanization and the deepening of environmental protection concepts, recycled permeable paving bricks have been widely used in municipal roads, squares, and landscaping projects due to their excellent permeability, environmental characteristics, and resource reuse advantages. In the production process of recycled permeable bricks, palletizing and packaging is a crucial step, and its efficiency and quality directly affect subsequent transportation, storage, and the product's appearance.

[0003] Currently, the stacking of most recycled permeable bricks still relies on manual labor or semi-automatic equipment, resulting in high labor intensity, low efficiency, and uneven stacking. To improve automation, some companies have introduced robotic arms in conjunction with clamping devices for automated stacking. However, existing clamping devices mostly use rigid clamping structures with fixed jaw dimensions, making it difficult to adapt to the dimensional tolerances of bricks caused by fluctuations in production processes. This can easily lead to unstable clamping, brick slippage, or even breakage, affecting the safety and stability of the stacking process.

[0004] Furthermore, before stacking the bricks, the surface often has residual dust or debris from demolding. If not cleaned properly, this will not only affect the appearance of the finished product but may also accumulate dust after packaging, reducing product quality. Additionally, the dust reduces friction, affecting transport stability. Traditional cleaning methods often rely on manual labor, which frequently leaves blind spots and results in ineffective cleaning. Therefore, a recycled permeable paving brick stacking and packaging machine is needed to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a recycling permeable pavement brick stacking and packaging machine, which has the advantages of stable clamping, strong adaptability, and high efficiency in cleaning. It solves the problems of existing equipment, such as brick slippage or damage due to rigid clamping, unstable clamping, and incomplete cleaning.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a recycled permeable pavement brick stacking and packaging machine, comprising a feeding conveyor, a six-degree-of-freedom robotic arm, a clamping mechanism and a material holding platform, wherein a dust blowing mechanism is provided on the clamping mechanism;

[0007] The clamping mechanism includes a fixed platform, grippers, a rotating shaft, and a telescopic cylinder. The grippers are mounted on the left and right sides of the fixed platform via the rotating shaft. The telescopic cylinder is fixedly mounted on the fixed platform to drive the grippers. The side end face of the grippers is provided with a sliding chuck that is elastically connected. The clamping mechanism is installed at the end of a six-degree-of-freedom robotic arm. The dust blowing mechanism includes a top tube, a shaft tube, and a spiral nozzle. The dust blowing mechanism is installed on the lower end face of the fixed platform.

[0008] In a preferred embodiment of the regenerated permeable paving brick stacking and packaging machine of this utility model, the inner side of the gripper is provided with a groove, a spring is provided in the groove, and the sliding chuck is installed in the groove and is elastically slidably connected to the gripper through the spring.

[0009] As a preferred embodiment of the present invention, a regenerated permeable paving brick stacking and packaging machine is provided with a first limiting flange on the edge of the chute, and a second limiting flange that cooperates with the first limiting flange is provided on the sliding clamp.

[0010] As a preferred embodiment of the regenerated permeable paving brick stacking and packaging machine of this utility model, the side end face of the sliding clamp is provided with a rubber strip.

[0011] In a preferred embodiment of the regenerated permeable pavement brick stacking and packaging machine of this utility model, the top pipe is fixedly installed on the lower end face of the fixed platform, the shaft pipe is installed on the lower end of the top pipe and rotatably connected thereto, and the spiral nozzles are evenly installed on the side end face of the shaft pipe.

[0012] As a preferred embodiment of the regenerated permeable paving brick stacking and packaging machine of this utility model, the end of the spiral nozzle is provided with an air outlet, and the side end face of the top pipe is provided with an air inlet that communicates with the air outlet.

[0013] As a preferred embodiment of the regenerated permeable paving brick stacking and packaging machine of this utility model, the bottom edge of the gripper is provided with a hook claw that protrudes inward.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model features a sliding chuck structure with a spring-loaded elastic connection on the side end face of the gripper. This, combined with the first limiting flange on the edge of the sliding groove and the second limiting flange on the sliding chuck, along with the hook design with the bottom edge of the gripper protruding inwards, significantly improves clamping stability and adaptability. The elastic sliding chuck automatically compensates for the dimensional tolerances of the permeable bricks, ensuring that bricks of different sizes can be stably clamped without slipping. The limiting flange prevents the chuck from accidentally popping out when the gripper is released. The hook at the bottom supports the bottom of the brick, increasing anti-slip friction. The rubber strip on the side end face of the sliding chuck provides cushioning, preventing hard contact from causing chipping or cracking of the brick edges. These structures work together to effectively solve the problems of unstable clamping, brick slippage, or damage caused by brick size differences and rigid clamping, ensuring the reliability of the stacking process and the integrity of the bricks.

[0016] 2. This utility model achieves efficient and comprehensive brick surface cleaning by setting a dust blowing mechanism on the lower end face of the clamping mechanism's fixed platform. The mechanism consists of a top tube, a rotatable shaft tube, and spiral nozzles evenly distributed on its side. Compressed gas enters from the air inlet at the side end of the top tube, flows through the shaft tube, and exits from the air outlet at the end of the spiral nozzle. The airflow reaction force drives the shaft tube to rotate, which in turn drives the spiral nozzle to rotate synchronously. The spiral-shaped nozzle design causes the airflow to be sprayed tangentially downwards. This dynamic rotating spraying method greatly expands the coverage of the airflow, reduces cleaning dead angles, and can effectively blow away dust and debris attached to the upper surface and side end face of the bricks at the same time. This structure solves the problem of cleaning blind spots in traditional fixed air blowing methods, ensuring that the brick surface is clean before clamping and stacking, thus improving packaging quality and product appearance.

[0023] Please see Figures 1-5 A recycling permeable paving brick stacking and packaging machine includes a feeding conveyor 2, a six-degree-of-freedom robotic arm 1, a clamping mechanism 3 and a material holding platform 4, and a dust blowing mechanism 5 is provided on the clamping mechanism 3;

[0024] The clamping mechanism 3 includes a fixed platform 301, a gripper 302, a rotating shaft 303, and a telescopic cylinder 304. The gripper 302 is mounted on the left and right sides of the fixed platform 301 via the rotating shaft 303. The telescopic cylinder 304 is fixedly mounted on the fixed platform 301 to drive the gripper 302. The side end face of the gripper 302 is provided with a sliding chuck 305 that is elastically connected. The clamping mechanism 3 is mounted at the end of the six-degree-of-freedom robotic arm 1. The dust blowing mechanism 5 includes a top tube 501, a shaft tube 502, and a spiral nozzle 503. The dust blowing mechanism 5 is mounted on the lower end face of the fixed platform 301.

[0025] Furthermore, a groove 3021 is provided on the inner side of the gripper 302, and a spring 307 is provided in the groove 3021. The sliding chuck 305 is installed in the groove 3021 and is elastically slidably connected to the gripper 302 through the spring 307.

[0026] The sliding chuck 305 and the gripper 302 are elastically connected by a spring 307, which can stably clamp the permeable bricks even when there are dimensional tolerances, preventing the bricks from slipping or cracking, and improving the stability of the brick clamping.

[0027] Furthermore, the edge of the slide groove 3021 is provided with a first limiting flange 3022, and the sliding chuck 305 is provided with a second limiting flange 3051 that cooperates with the first limiting flange 3022.

[0028] The first limiting flange 3022 and the second limiting flange 3051 cooperate to limit the stroke of the sliding chuck 305 and prevent the sliding chuck 305 from popping out when the chuck 302 is released.

[0029] Furthermore, a rubber strip 306 is provided on the side end face of the sliding chuck 305.

[0030] The rubber strip 306 is made of soft material to prevent gaps from forming on the edge of the permeable brick when the sliding clamp 305 holds the brick, thus affecting the appearance of the brick.

[0031] Furthermore, the bottom edge of the gripper 302 is provided with an inwardly protruding hook 3023.

[0032] The bottom of the permeable brick is supported by the hook 3023 to prevent the permeable brick from slipping due to insufficient friction, thus further improving the stability of the equipment clamping.

[0033] Furthermore, the jacking pipe 501 is fixedly installed on the lower end face of the fixed platform 301, the shaft pipe 502 is installed on the lower end of the jacking pipe 501 and rotatably connected to it, and the spiral nozzles 503 are evenly installed on the side end face of the shaft pipe 502.

[0034] The rotating shaft tube 502 structure can drive the spiral nozzle 503 to rotate, thereby increasing the coverage area of ​​the spiral nozzle 503, reducing blind spots in the blowing process, and improving the dust blowing effect.

[0035] Furthermore, the end of the spiral nozzle 503 is provided with an air outlet 505, and the side end face of the top tube 501 is provided with an air inlet 504 that communicates with the air outlet 505.

[0036] Airflow enters the top tube 501 through the air inlet 504, flows through the shaft tube 502 to each spiral nozzle 503, and finally exits through the air outlet 505. This causes the shaft tube 502 to rotate around the shaft tube 502 under the reaction force of the airflow. The spiral nozzle structure blows out airflow at an angle downward along the tangential direction, which can sweep both the top surface and the side surface of the brick.

[0037] When using this equipment, first connect the air inlet 504 to the air compressor in the workshop, and transport the recycled permeable paving bricks to be stacked and packaged to the feeding conveyor 2. After the equipment is started, the six-degree-of-freedom robotic arm 1 moves the clamping mechanism 3 installed at its end to a suitable position above the feeding conveyor 2 according to the preset program or instructions. At this time, the telescopic cylinder 304 is activated, driving the gripper 302 to rotate around the rotating shaft 303 and open. The sliding chuck 305 is elastically connected to the gripper 302 through the spring 307, and will adjust its position appropriately according to the size of the brick during the opening process. Then, the clamping mechanism 3 descends until the gripper 302 surrounds the permeable brick. The telescopic cylinder 304 is activated again to close the gripper 302. The sliding chuck 305 is tightly attached to the side of the permeable brick under the action of the spring 307. At the same time, the hook 3023 on the bottom edge of the gripper 302 supports the bottom of the permeable brick to ensure that the brick is stably clamped. Before the dust blowing mechanism 5 starts working, the external airflow enters from the air inlet 504 on the side end face of the top pipe 501, flows through the top pipe 501 to the shaft pipe 502, and then is divided by the shaft pipe 502 to each spiral nozzle 503, and is discharged from the air outlet 505 at the end of the spiral nozzle 503. Due to the reaction force of the airflow, the shaft pipe 502 drives the spiral nozzle 503 to rotate around its own axis. The airflow blown out by the spiral nozzle 503 is inclined downward along the tangential direction, and blows the upper end face and side end face of the permeable brick to remove dust and impurities from the surface of the brick. After the dust blowing and clamping operation is completed, the six-degree-of-freedom robotic arm 1 moves the clamping mechanism 3 holding the permeable brick to the top of the material receiving platform 4. The telescopic cylinder 304 reverses the action to open the gripper 302, and the sliding chuck 305 is reset under the action of the spring 307. The permeable brick is placed stably on the material receiving platform 4 and stacked in sequence. After the stacking is completed, it is transferred to the next process by the workshop forklift.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
