Tool magazine installation and related PLC parameter setting

Operation purpose: make the ladder diagram match the configuration of the tool magazine

The requirements for the machine tool when this ladder diagram is equipped with a disc-type tool magazine:

The machine tool has an automatic clamping/releasing device for spindle tools, and the automatic clamping/releasing device is equipped with a normally open in-position detection switch

The spindle has a positioning function, and the positioning angle can be adjusted

The capacity of the tool magazine is less than 100

(The setting value of D100 must be less than 100 and the same as the setting value of CTR100, otherwise an abnormality will occur.)

For example: when D100=16, data sheet D001-D016 is valid;

When D100=24, data sheet D001-D024 is valid

Tool magazine can rotate forward and reverse

The tool magazine has a counting switch, a forward in-position detection switch, and a backward in-position detection switch

The tool magazine has a zero return switch

Connection between B and tool magazine related lines:

Input part

 

Note: For example: there is a disk-type tool magazine without a zero return switch, and each detection switch is a normally open type, and the parameters should be set as:

K010.1=0, K010.2=0, K010.3=0, K010.4=0, K010.5=0

 

 

 

 

 

Tool magazine capacity setting

Enter the tool magazine capacity in DATA100 and CTR100

Note:

Tool magazine capacity refers to the number of tool pockets in the tool magazine

The setting value of DATA100 and CTR100 must be less than 100

For example: when the tool magazine capacity is 16, set DATA100 to 16, and CTR100 to 16

 

 

 

Setting of tool number in tool magazine

Data sheets D001-D099 correspond to tool magazines No. 1 to 99 respectively, and the setting values ​​in data sheets D001-D099 correspond to tool magazines No. 1 to 99. D245 is the tool number on the spindle.

Note:

The same tool number cannot be set in D001-D099 (except 0)

Otherwise, an alarm will appear when changing the tool

The setting range of the tool number must meet the requirements set by parameter 0206, otherwise an alarm will occur when the T code is executed

For example: when the capacity of the tool magazine is 24, if it is set to 1-24 in D1-D24 in turn, when T8M6 is executed, the No. 8 tool sleeve will be rotated to the tool change position and the tool exchange will be performed. If it is set in D1-D24 in turn 10, 20, 30. . . . . 240. When T80M6 is executed, tool holder No. 8 will be rotated to the tool change position and the tool exchange will be executed. If both D1 and D2 are set to 8, an alarm will occur when T8M6 is executed

 

 

 

Manual and zero return operation of tool magazine

Operation purpose: check whether each step of the tool magazine is normal

The specific steps are as follows

Effective use of tool magazine

By default, the system uses Ladder01.grp ladder diagram, that is, the ladder diagram of the hat-type tool magazine. To use the disc tool magazine, the Ladder00.grp ladder diagram must be enabled, the in-place parameter NO:53#0=0, NO:53#1=0, NO:53#2=0, NO:53#3=0. Modify After the parameter, the system needs to be powered off and restarted

PMC ladder diagram parameter K001.0 is set to 1

 

 

 

 

 

 

Tool magazine enters adjustment mode

PMC's ladder diagram parameter 012.7 is set to 1

In order to facilitate the debugging of the concentricity of the tool magazine gripping position with the spindle and the Z axis gripping position, the PMC parameter of the tool magazine debugging can be set. When K012.7 is set to 1, the condition restriction of manipulator operation can be cancelled, and the tool magazine debugging state can be entered. After debugging, please set K012.7 to 0. The data at this time will not be exchanged

Under normal circumstances, manually run the manipulator steps

The Z axis returns to the tool change point (in the MDI mode, enter G30G91Z0 to return it to the manipulator tool change point) and set K10.7 to 1

Spindle orientation (press the spindle stop key in manual mode to complete the orientation)

The tool holder is vertical (in manual mode, press the tool magazine advance and retreat button to make the tool holder vertical in position)

Manual manipulator movement to grab the knife (in manual mode, press the "tool changer" button to complete the manipulator movement 1)

Release the knife (in manual mode, press the clamp/release tool to loosen the knife and release the knife in place)

Manual manipulator movement to change the knife (press the changer button again to complete the manipulator movement 2)

Clamp the knife (press the clamping knife/release the knife again to tighten the knife and tighten the knife in place)

The manual manipulator moves back to the manipulator origin (press the tool changer button for the third time to complete the manipulator movement 3)

Manual manipulator movement completed

Under normal circumstances, manual operation of the manipulator conditions

The spindle orientation is completed, the tool sleeve is in place vertically, and the Z axis returns to the tool change point

 

 

 

 

 

Determination of the direction of rotation of the tool magazine

In manual mode, press the counterclockwise button of the tool magazine, and the tool magazine will rotate in the increasing direction of the tool number. Press the clockwise button of the tool magazine, and the tool magazine will rotate in the decreasing direction of the tool number. If the opposite phenomenon occurs, the tool magazine count will be disordered, resulting in Tool exchange error, adjust the phase sequence of the rotating motor of the tool magazine to solve this problem

 

 

 

 

 

The zero return operation of the tool magazine

The zero return operation of the tool magazine is divided into two situations: with zero return switch and without zero return switch:

When the tool magazine has a zero return switch: press the tool magazine to zero in the "mechanical zero return" mode, and when the "tool magazine zero indicator light" is on, the zero return is complete (the light flashing indicates that the tool magazine is returning to zero)

When the tool magazine has no zero return switch, set the tool magazine zero point according to the following steps:

In manual mode, press the tool magazine counterclockwise or tool magazine clockwise button to rotate the No. 1 tool sleeve of the tool magazine to the tool exchange position

 

In the input mode, set K010.6 to

 

In the mechanical zero return mode, press the tool magazine zero return until the "tool magazine zero indicator light" is on

 

 

Set K010.6 to 0

 

 

 

 

 

 

Manual adjustment after the tool magazine stops abnormally

When the manipulator is powered off or the emergency stop or reset button is pressed during operation, the manipulator needs to be re-adjusted to return to the zero position. First set K010.7=1 to make the tool magazine enter the adjustment state, and adjust the manipulator back to zero according to the steps of manually running the manipulator above. If it cannot be ruled out, set K012.7=1 to make the manipulator enter the adjustment state, and it is released in this state. All restrictions on the operation of the manipulator should be operated carefully. After adjusting the manipulator back to zero, set K010.7=0, K012.7=0, and the manipulator can operate normally.
