Description

Technical Field

[0001] This utility model relates to the technical field of impeller palletizing equipment, and in particular to a palletizing device for impeller production and processing. Background Technology

[0002] In the impeller manufacturing process, impeller inspection is a key step in ensuring product quality. After inspection, qualified impellers need to be stacked and stored for subsequent transportation and assembly.

[0003] The commonly used impeller palletizing methods in the industry currently have the following main problems: 1. In some scenarios, direct stacking is used. When the impeller falls from the inspection station, there is no buffer structure. The impact force is large when it falls, which can easily cause the impeller to collide with the stacked impellers below and be damaged, increasing production costs. Second, the existing impeller palletizing device has few palletizing stations per operation (mostly 1-2). When the impellers at a single station are full, the testing line needs to be paused and the palletizing station needs to be changed manually or the impeller stack needs to be moved. The operation is cumbersome and time-consuming, which seriously affects the overall efficiency of the testing line. Utility Model Content

[0004] To address the issues of insufficient stacking stations, the need for machine shutdown to handle impeller stacks, and the susceptibility of impellers to collision damage during stacking, this application provides a stacking device for impeller production and processing.

[0005] The palletizing device for impeller production and processing provided in this application adopts the following technical solution: A stacking device for impeller production and processing includes a base plate, a mounting frame horizontally arranged on the base plate, a drive assembly between the base plate and the mounting frame, an air supply pipe horizontally arranged inside the mounting frame, one end of the air supply pipe being closed, and the other end being connected to an external air supply device via a flexible hose, a branch pipe vertically arranged on the air supply pipe, and several branch pipes equidistantly arranged along the length of the air supply pipe, a first air passage opening vertically inside the branch pipe, the first air passage communicating with the air supply pipe, a second air passage opening on both sides of the branch pipe communicating with the first air passage, the second air passage being inclined upwards, and several second air passages equidistantly arranged along the height of the branch pipe, and a material rack for loading impellers being sleeved on the branch pipe.

[0006] Preferably, the drive assembly includes a bearing housing, a threaded rod, a nut seat, a mounting plate, a connecting plate, a slider, a guide rail, and a drive motor. The bearing housing is connected to the base plate, and two bearing housings are arranged opposite each other on the base plate. The threaded rod is connected between the two bearing housings. The nut seat is threaded onto the threaded rod. The mounting plate is connected to the nut seat. The connecting plate is connected to the mounting plate and to the mounting frame. The drive motor is connected to the base plate, and the output shaft of the drive motor is coaxially connected to the threaded rod via a coupling. The guide rail is connected to the base plate and is arranged parallel to the threaded rod. One guide rail is provided on each side of the threaded rod. The slider is connected to the mounting plate, and the slider slides with the guide rail.

[0007] Preferably, a solenoid valve is connected to the branch pipe, and the solenoid valve is located at the bottom end of the branch pipe.

[0008] Preferably, the angle between the first airway and the second airway is 30° to 60°.

[0009] Preferably, the material rack includes a support plate and a limiting rod. The support plate is arranged in a disc shape, and a through hole for the branch pipe to pass through is opened in the center of the support plate. The limiting rod is fixedly connected to the support plate and is arranged in a direction perpendicular to the support plate. Several limiting rods are arranged at equal intervals along the circumference of the support plate.

[0010] Preferably, a fixing frame is connected to the base plate, the fixing frame is located on one side of the mounting frame, and an infrared distance sensor is connected to the fixing frame. The infrared distance sensor is used to monitor the distance between itself and the top of the branch pipe.

[0011] In summary, this application includes the following beneficial technical effects: This utility model provides a stacking device for impeller production and processing. By setting up an installation frame, a drive assembly, a main pipe, branch pipes, and a material rack, during stacking, the branch pipe passes through the shaft hole of the impeller, causing the impeller to fall from top to bottom. The airflow inside the branch pipe, after passing through a second air passage, generates upward resistance on the impeller, which can offset part of the impeller's weight, slow its falling speed, and improve its rigid collision with the impeller below. The material rack can circumferentially limit the impeller, preventing it from shifting or bumping during its fall. The material rack also facilitates workers to remove the entire stack of impellers upwards. When the impellers on a branch pipe reach a specified number, the drive assembly drives the installation frame to move laterally, placing the next branch pipe below the inspection station. This allows for the removal of the stacked impellers without stopping the machine, thus improving the problems of insufficient stacking stations, the need to stop the machine to handle the impeller stacks, and the susceptibility of impellers to collision damage during stacking.

[0017] During operation, the threaded rod 32 is driven to rotate by the drive motor 38. Under the limiting action of the slider 36 and the guide rail 37, the nut seat 33 can move along the length direction of the threaded rod 32, thereby driving the components on the mounting frame 2 to move laterally and adjust their positions.

[0018] An air supply pipe 4 is horizontally installed inside the mounting frame 2. One end of the air supply pipe 4 passes through the side wall of the mounting frame 2. A fixing plate is connected inside the mounting frame 2, and the other end of the air supply pipe 4 passes through the fixing plate and is fixed.

[0019] One end of the air supply pipe 4 is closed, and the other end is connected to an external air supply device through a hose. The air supply device consists of an air pump, an air storage tank, and a regulating valve (this is existing technology and will not be described in detail in this embodiment). The air pump generates compressed air, which is then delivered to the air pipe after being stabilized by the air storage tank. The regulating valve can adjust the outlet pressure according to the impeller weight to ensure that the buffer force is adapted to impellers of different specifications.

[0020] A branch pipe 5 is vertically installed on the gas supply pipe 4. Several branch pipes 5 are arranged at equal intervals along the length of the gas supply pipe 4. The top of the branch pipe 5 is closed. A first air passage 51 is opened in the vertical direction inside the branch pipe 5. The first air passage 51 is connected to the gas supply pipe 4. A second air passage 52 is opened on both sides of the branch pipe 5 and is connected to the first air passage 51. The second air passage 52 is inclined upward.

An infrared distance sensor 111 is connected to the mounting bracket 11. The infrared distance sensor 111 is used to monitor the distance between itself and the top of the branch pipe 5. When the change in the distance between the infrared distance sensor 111 and the top of the branch pipe 5 exceeds 3 seconds, the drive assembly 3 is started.

Then, the detected impellers fall one by one, passing through the impellers and stacking them. When they are stacked to a certain height, the infrared distance sensor 111 detects the change in distance between itself and the top of the branch pipe 5. After the change time exceeds three seconds, the drive component 3 drives the mounting frame 2 to move laterally, so that the second branch pipe 5 is located directly below the detection station, and the solenoid valve 53 on the second branch pipe 5 is opened, while the solenoid valve 53 on the first branch pipe 5 is closed, and the palletizing operation continues. At the same time, the operator can directly lift the material rack 6 on the first branch pipe 5 and take out the stacked impellers as a whole.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments.
