常用的机械手刀库乱刀问题，大致可以分为二大原因造成：
There are two main reasons for the frequently used tool magazine mess.
一、刀盘计数问题
First, the problem of the counting of the knives and plates
1、在刀盘旋转的过程中，当铁屑飞入计数开关处感应一次，或者刀库计数信号端子接触不良等，计数信号就会误计数，造成当前刀套号不正确，出现乱刀。
1, in the process of rotating the knife plate, when the iron chip flies into the counting switch, or the terminal contact of the count signal terminal is bad, the count signal will be counted mistakenly, which causes the current knife sleeve to be incorrect, and a random knife appears.
2、在刀盘旋转的过程中突然急停或断电等原因，刀盘停在二个刀套中间的位置。假如刀盘正转时从1号刀套转到2号刀套过程中断电，刀套停在1和2号刀套中间位置，此时计数信号并没有计数，当前刀套值还是1，开机后，如果手动按刀盘反转调整刀库位置，刀库刀套旋转到1号位置，但当前刀套号值减1就变了24（24把刀库），就出现了乱刀。上述情况反之也乱刀。
2, in the process of cutting the disc in the process of abrupt sudden stop or power failure and other reasons, the cutterhead is in the middle of the two knives. If the knife plate is turning from No. 1 knife sleeve to No. 2 knife sleeve, the knife sleeve is stopped in the middle of 1 and 2. At this time the count signal is not counted, and the value of the knife sleeve is still 1. After the machine is opened, the knife sleeve is rotated to the No. 1 position if the tool disk is reversed manually, but the value of the knife sleeve is reduced by 2 at present. 4 (24 knife library), there is a random knife. The above situation is vice versa.
二、刀库数据表刷新问题。
Two. The database table refresh problem.
因为机械手刀库是随机换刀，所以要刷新刀具表，即机械手交换后，主轴刀具号与当前刀套刀具号交换。交换的时机非常关键，各个厂家PLC交换时机不尽相同。有的厂家是刀臂180交换检测到夹刀信号数据交换，有的厂家是刀臂回刀后数据交换，有的厂家是检测到刀套抬起信号数据交换。
Because the manipulator magazine is randomly changing the tool, it is necessary to refresh the tool list, that is, after the manipulator exchanges, the spindle tool number is exchanged with the current cutter number. The timing of exchange is very critical, and the timing of PLC switching is different. Some manufacturers are the tool arm 180 exchange detection to the clip knife signal data exchange, some manufacturers are the tool arm back to the knife data exchange, some manufacturers are detecting the knife sleeve to raise the signal data exchange.
在换刀的过程中，刀臂180度交换到位时，刷新数据表是最好时机。刀臂180度交换到位，如果此时出现报警卡刀，主轴松刀电磁阀就会停止输出把主轴刀具夹紧，此时主轴刀具到了刀库刀套里，刀库刀套的刀具到了主轴上，数据表也交换了，只要手动把机械臂摇回即可，也不需要重新排刀。
In the process of tool changing, when the cutter arm is exchanged in 180 degrees, it is the best time to refresh the data table. When the knife arm is in place at 180 degrees, the spindle knife solenoid valve will stop to clamp the spindle tool if there is an alarm card at this time. At this time, the spindle tool has come to the knife sleeve of the knife library. The tool set tool of the knife library has come to the spindle, and the data sheet is also swapped back.
