The safety light curtain 23 is installed on the side of the connecting port away from the processing cavity. The safety light curtain 23 is used to detect whether there is an object at the connecting port to avoid clamping the object when closing.

[0067] The control method of the automatic door is as follows: after the automatic door is turned on by the main power supply, the automatic door automatically opens after sensing the material, and automatically closes after loading and unloading is completed to complete the action.

[0068] Specifically, the control process of the automatic door can define input and output variables:

[0069] The input part is as follows:

[0070] Emergency stop button: The variable value is 1 when pressed and 0 when released. It is used to manually trigger the door opening and closing stop operation.

[0077] Unloading completion sensor: The signal is 0 when the unloading operation is completed, and 0 when the unloading is not completed. It is used to feedback whether the unloading is completed.

[0078] Material loading in place sensor: When the material reaches the specified position, the sensor signal is 1, and when the material is not in place, it is 0. It is used to determine whether the material loading position is accurate.

[0079] Material unloading position sensor: When the material unloading reaches the specified position, the sensor signal is 1, and when the material unloading is not in place, it is 0. It is used to judge whether the material unloading position is accurate.

[0080] The output section is as follows:

[0081] Cylinder blowing (opening the door): When the output value is 1, the air intake at one end of the cylinder is controlled, thereby driving the door to open; when the output value is 0, the air intake of the cylinder is controlled to be closed.

[0082] Cylinder blowing (door closing): When the output value is 1, the air intake at one end of the cylinder is controlled, thereby driving the door to open; when the output value is 0, the air intake of the cylinder is controlled to be closed.

[0083] Door opening indicator light: When the output value is 1, the door opening indicator light is on, indicating that the door is currently in the open state or the door opening operation is being performed; when the output value is 0, the indicator light is off.

[0084] Door closing indicator light: When the output value is 1, the door closing indicator light is on, indicating that the door is closing or the door is in the closed state; when the output value is 0, the indicator light is off.

[0085] Loading indicator light: When the output value is 1, the loading indicator light is on, which can be used to prompt the loading related operation status; when the output value is 0, the indicator light is off.

[0086] Unloading indicator light: When the output value is 1, the unloading indicator light is on to prompt the unloading related operation status; when the output value is 0, the indicator light is off.

[0087] Program segment: automatic door control logic.

[0088] The emergency stop process corresponds to the following:

[0089] The emergency stop button is assigned a value of 1, then:

[0090] Safety light curtain signal, the variable value input is 0, indicating that an obstacle is detected. At this time, the door movement needs to stop to ensure safety.

[0091] When the cylinder air blowing (door opening) variable value is input as 0, the cylinder air intake stops and the automatic door stops.

[0092] When the cylinder air blowing (door closing) variable value is input as 0, the cylinder air intake stops and the automatic door stops.

[0093] Assign the value of the emergency stop button to 0 to turn off the state.

[0094] The automatic modes are as follows:

[0095] When in automatic control mode:

[0096] If the following conditions are met, that is, (loading is not completed and loading is in place) or (unloading is not completed and unloading is in place), and the safety light curtain is not blocked, and the door has not been fully opened:

[0097] The corresponding door opening logic is as follows:

[0098] The cylinder blowing (opening the door) is assigned a value of 1, which allows air to enter the cylinder and drive the door to open;

[0099] The door opening indicator light is assigned a value of 1, and the door opening indicator light is on;

[0100] The door closing indicator light is assigned a value of 0, and the door closing indicator light is off.

[0101] If the value of the upper limit door position sensor becomes 1, that is, the door is fully opened, then the cylinder blowing (door opening) is assigned a value of 0, the cylinder stops taking in air, and the door opening action ends.

[0102] Closing logic:

[0103] The cylinder blowing (door closing) is assigned a value of 1, which allows air to enter the cylinder and drive the door to close;

[0104] The door closing indicator light is assigned a value of 1, and the door closing indicator light is on;

[0105] The door opening indicator light is assigned a value of 0, and the door opening indicator light is off.

[0106] When the value of the lower limit door position sensor becomes 1 (that is, the door is completely closed), the cylinder blowing (door closing) is assigned a value of 0, the cylinder stops taking in air, and the door closing action is completed.

[0107] Feeding logic:

[0108] If loading is not complete) and the door is fully open, then:

[0109] Here you can add relevant codes such as starting the feeding equipment (currently it is just an example, no detailed operation code has been added yet);

[0110] The loading device (robot) is assigned a value of 1, and the loading indicator light turns on.

[0111] If the loading is completed, the loading device (robot) is assigned a value of 0 and the loading indicator light goes out.

[0112] Cutting logic:

[0113] When unloading is not completed and the door is fully opened:

[0114] Here you can add relevant codes such as starting the unloading equipment. Currently it is just an example and no detailed operation code has been added yet;

[0115] The unloading equipment (machine tool) is assigned a value of 1, and the unloading indicator light is on.

[0116] If unloading is completed, the unloading equipment (machine tool) is assigned a value of 0 and the unloading indicator light goes out.

[0117] The entire program controls the corresponding output signals by judging different input signals, thereby realizing the functions of opening and closing the door and providing operation prompts related to loading and unloading in a reasonable and safe manner in automatic mode according to relevant conditions such as loading and unloading.

[0118] The following two commands require the use of a three-position, five-way, center-sealed solenoid valve for control (when the cylinder air intake stops, the piston rod position is fixed).

[0119] When the cylinder air blowing (door opening) variable value is input as 0, the cylinder air intake stops and the automatic door stops.

[0120] When the cylinder air blowing (door closing) variable value is input as 0, the cylinder air intake stops and the automatic door stops.

[0121] The loading and unloading materials of machine tools are usually fixed materials. The automatic door structure of this machine tool can adjust the upper and lower limits according to the specific material size to improve the processing efficiency.
