[0016] The present invention also provides a working method of a linkage device for pipe connection, pipe delivery and pipe ferrying of a pipe making machine, comprising the following steps:

[0017] S1. The tube making machine of the previous process synchronously transports a group of manufactured tubes to a group of tube blanking plates arranged in parallel. A group of tubes are simultaneously dropped from above a group of tube blanking plates arranged in parallel into a tube drop groove 1. When the tubes fall, the vacuum air path draws a vacuum through a group of vacuum air holes 1, forming a negative pressure on the inner wall of the tube drop groove 1, so that the tubes fall stably into the tube drop groove 1 to avoid bouncing.

[0018] S2, the pipe pushing drive motor starts, driving the driving wheel to rotate, so that the pipe pushing belt is driven, and the pipe pushing belt drives the push plate slide to move linearly along the push plate slide rail, and the movement direction is from the pipe body blanking plate to the pipe connecting plate;

[0019] S3, the push plate slide drives the tube pusher to move linearly, and the tube pusher pushes the tube set in the tube drop groove 1 into the tube drop groove of the tube plate. When the tube pusher pushes the tube, the air path of a group of vacuum air holes 1 is disconnected, and the tube drop groove 1 can release the tube;

[0020] S4, the tube body enters the tube blanking trough, a group of vacuum vents are vacuumed, and negative pressure is formed on the inner wall of the tube blanking trough, so that the tube body stably enters the tube blanking trough until the tube body in the tube blanking trough contacts the tube body stopper, the tube body pusher stops pushing, and the tube body pusher returns to the initial tube blanking plate position;

[0021] S5, the ferry driving motor starts, driving the ferry driving wheel to rotate, the ferry driving wheel drives the ferry driven wheel to rotate through the ferry transmission belt, the ferry driven wheel drives the transmission shaft to rotate, the transmission shaft drives the swing arm to swing in a circle with the center of the transmission shaft as the center, so that a group of pipe body suction nozzles connected to the suction nozzle bracket move to the top of the take-over plate;

[0022] S6, while step S5 is being performed, the ferry driven wheel 2 rotates following the transmission shaft 1, the ferry driven wheel 2 drives the ferry driven wheel 3 to rotate through the ferry transmission belt 2, and the ferry driven wheel 3 drives the ferry rotating shaft to rotate, so that a group of tube body suction nozzles connected to the suction nozzle bracket are in a vertical downward position;

[0023] S7, the air path of a group of vacuum air holes 2 is disconnected, the pipe blanking trough releases the pipe body, and at the same time a group of pipe body suction nozzles suck the pipe body in the pipe blanking trough of the pipe plate;

[0024] S8, the ferry drive motor is started in the reverse direction relative to step S5, the principle is the same as S5 and S6, so that a group of tube suction nozzles adsorbing the tube body swing to the direction of the tube body conveyor belt, and a group of tube suction nozzles release the tube body on the tube body conveyor belt;

[0025] S9, continuously repeating the above steps S1 to S8, continuously and automatically conveying a group of tubes to the tube conveyor belt.

[0026] By monitoring the pipe-discharging action of the pipe-making machine and matching the pipe-discharging action of the pipe-taking stabilizing mechanism, and adding a negative pressure adsorption structure to the pipe-dropping trough and the pipe-dropping trough, the disorderly pipe-discharging phenomenon of the pipe-making machine is greatly stabilized, laying an operational foundation for subsequent automatic packing and online defective product detection, which can greatly reduce the production of unnecessary personnel, greatly improve the human-machine production efficiency, reduce production costs, and enhance the core competitiveness of the enterprise.

[0027] It can be seen from the above technical scheme that the present invention has the following beneficial effects: the linkage device for pipe connection, pipe delivery and pipe ferrying of the pipe making machine of the present invention has the following advantages:

[0028] 1. Eliminate unnecessary manual arrangements and improve all replaceable repetitive labor to automated production modes as much as possible, laying the foundation for subsequent online defect detection and automatic packaging;

[0029] 2. Reduce costs, reduce costs in the production process by replacing manual labor with automated equipment, and enhance the core competitiveness of the enterprise;

[0030] 3. Reliability and stability are improved. Automated equipment replaces manual work, which avoids the missed inspection of defects and disordered pipe arrangement caused by physiological fatigue caused by long-term manual work;

[0031] 4. Organically combine production equipment designed by different manufacturers, break the production barriers caused by different suppliers, and lay the foundation for realizing the assembly line of segmented production equipment;

[0032] 5. Through the subsequent automatic packaging and online defect detection process, the purpose of compressing the storage space of semi-finished products, facilitating logistics turnover, shortening delivery time and improving product quality stability is achieved;

[0033] 6. Break the shackles of the labor shortage during the epidemic, achieve a leap in productivity, and provide guarantees for the company to further expand its customer base and meet product delivery deadlines;

[0034] 7. Innovatively combining different equipment organically breaks the mindset of traditional production models and points out the direction of automation for industry development.

[0035] The linkage device for pipe connection, pipe delivery and ferrying of the pipe making machine described in the present invention matches the subsequent pipe discharging action by monitoring the action of the pipe turner when the pipe making machine discharges the pipe and the vehicle speed. The pipe discharging action is driven by a servo motor. When the pipe is dropped, there are vacuum air holes for adsorption. After being pushed out, the corresponding ferrying part places the product on the conveyor belt for pipe sorting, thereby ensuring the stability of the product during transportation and avoiding the inability to achieve the automation improvement plan of the subsequent actions due to disorder.
