As shown in Figure 16, the chain joint assembly machine provided by the present invention is opened by a PLC control device, each component is started, the motor is started, the spindle is rotated, and the six control cams on the spindle are rotated. The respective sensors also start to work. First, the pin shaft cam rotates to a predetermined position, the sensor sends a signal to the controller, and the controller controls the feed pin device at the first station to start, and delivers the target pin to the work carousel. The first groove on the upper end, after the conveyance is completed, one process ends, the work turntable rotates one station, and at the same time, the feed pin on the motor main shaft When the shaft cam rotates one turn, the feed pin shaft device performs the next feed pin shaft operation, the work turntable continues to rotate, and the target pin shaft rotates to the third pair of grooves (ie, reaches the third station), at which time the corresponding motor spindle is The outer film cam is rotated to a predetermined position, and the control device controls the outer film device to push the outer piece. When the outer piece is pushed to the appropriate position, the first loading cam on the motor main shaft is rotated to a predetermined position, and the control device controls the loading device to start. When the guiding kick of the loading device is about to leave the pin, the second loading cam on the motor main shaft is rotated to a predetermined position, and the control device controls the loading hydraulic cylinder to push the pressing die downward until the chain reaches the predetermined position, the hydraulic pressure When the cylinder is up, the loading is completed, the motor spindle continues to rotate, and the working turntable and several cams on the main shaft are rotated together, and the target pin of the loading piece is turned to the sixth pair of grooves (ie, reaching the sixth station), and At the same time, the circular rivet cam on the motor main shaft is rotated to a predetermined position, and the control device controls the first round rivet device and the second round rivet device for round riveting (in the continuous production, the first round riveting And the pin of the second round riveting device has a pin for completing the loading), realizing a round riveting of the pin for completing the loading, the working turntable continues to rotate, to the ninth pair of grooves (the ninth station) ), for the second round riveting, the work turntable continues to rotate, and the assembled chain joint exits the work turntable from the eleventh pair of grooves.

That is, six control cams are mounted on the main shaft of the present invention, and the feed pin shaft device, the outer sheet feeding device, the loading device (two cams are required), and the round riveting device (two circular riveting devices share one cam) are respectively controlled. Stop positioning. Each cam corresponds to a sensor. When the sensor receives the convex surface of the cam, it sends a PLC signal. The PLC output signal drives the cylinder of the device to move forward. When the protruding surface is away from the sensor, the cylinder retreats. Further, in the chain joint assembling machine of the present invention, a limit sensor is mounted on the feed pin shaft device and the outer sheet feeding device. If the push module of the feed pin device is in the process of pushing, the front is blocked and cannot be pushed to the position. Here, the push module sensor does not sense the information of the push module in place at a predetermined time, and sends information to the control device, and the PLC control device will The alarm device will be instructed to issue an alarm signal. Similarly, when the feed plate cannot be successfully reached or returned to the predetermined position, the blade sensor will also send a signal to the control device, and the control device will indicate the alarm.

The invention adopts a stop cam for stopping control. When the stop button is pressed, the PLC control device continues to wait for the signal of the stop cam. When the stop cam is protruded (ie, the stop cam rotates to a predetermined position, each process is here) In the state of being in a standby state, the shutdown is safe. When the sensor head is close to the sensor, the shutdown is performed. With this shutdown control method, the shutdown is only When each process is returned, it avoids the sudden stop of each process while it is running, resulting in waste, and it is also easy to repair or work reliably next time.

The above-mentioned embodiments are merely illustrative of the embodiments of the present invention, and the description thereof is not to be construed as limiting the scope of the invention. It should be noted that a number of variations and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention.
