Storage is for making cutting knife 30 required mobile umber of pulse b0 from origin position moves to the cut-out end position in memory 72.
＜cloth cuts off to be handled 〉
(detection of obstacles)
Cloth shown in Figure 4 cuts off the control of the detection of obstacles in handling and is carried out by CPU71.
When carrying out the cut-out of cloth, at first, judge on the mobile route of cutting knife 30, whether there is barrier by cloth cut off device 10.
Read the contact detection deviation f0 and the detection range umber of pulse c0 (step S1) that are stored in the memory 72.
Then, the driving command pulse is sent to pulse motor 11.The pulse motor 11 that receives the driving command pulse makes cutting knife 30 declines (step S2).
Then, be received in the driving pulse (step S3) of the reality of the pulse motor 11 when pulse motor 11 sends the driving command pulse from encoder 12.
Then, by carrying out the deviation calculation program, the deviation between the number of drive pulses P2 of calculating driving command umber of pulse P1 and reality judges that whether the deviation that calculates is greater than the contact detection deviation f0 (step S4) that is stored in the memory 72.
In step S4, judge that the deviation that calculates surpasses under the situation of contact detection deviation f0 (step S4: be), owing to judge that cutting knife 30 contacts with barrier on mobile route, so executive control program, the driving of pulse motor 11 is stopped, making mobile the stopping (step S5) of cutting knife 30.In addition, in step S5, after cutting knife 30 is stopped, making cutting knife 30 risings and get back to origin position.
On the other hand, in step S4, judge that the deviation that calculates does not surpass (step S4: not) under the situation of contact detection deviation f0, by the number of drive pulses P2 by encoder 12 detected reality, whether the position of judging cutting knife 30 exceeds from origin position begins to the detection range (step S6) between the height and position corresponding with detection range umber of pulse c0.That is, judge that whether the number of drive pulses P2 of detected reality is above the detection range umber of pulse c0 that is stored in the memory 72.
In step S6, the position of judging cutting knife 30 has exceeded from origin position and has begun to the situation of the detection range between the height and position corresponding with detection range umber of pulse c0 (step S6: be), carries out the cut-out (step S7) of cloth.
On the other hand, in step S6, the position of judging cutting knife 30 does not exceed and begins from origin position that (step S6: not), CPU 71 returns the processing of step S2 once more to the situation of the detection range between the height and position corresponding with detection range umber of pulse c0.
(cloth cut-out)
Below, the cut-out action of the cloth among the description of step S7.
As shown in Figure 5, when carrying out the cloth cut-out by cloth cut off device 10, CPU 71 reads allowable deviation a0 and the mobile umber of pulse b0 (step S11) that is stored in the memory 72.
Then, the driving command pulse is sent to pulse motor 11.The pulse motor 11 that receives the driving command pulse makes cutting knife 30 declines (step S12).
Then, be received in the driving pulse (step S13) of the reality of the pulse motor 11 when pulse motor 11 sends the driving command pulse from encoder 12.
Then, the deviation between the number of drive pulses P2 of calculating driving command umber of pulse P1 and reality judges that whether the deviation that calculates is greater than the allowable deviation a0 (step S14) that is stored in the memory 72.
In step S14, judge that the deviation that calculates surpasses under the situation of allowable deviation a0 (step S14: be), to compare with the mobile umber of pulse b0 that is stored in the memory 72 by the number of drive pulses P2 of encoder 12 detected reality, judge whether cutting knife 30 has arrived cut-out end position (step S15).
On the other hand, in step S14, judge that the deviation that calculates does not surpass (step S14: not), carry out the processing of step S12 once more under the situation of allowable deviation a0.
In step S15, judge that cutting knife 30 does not arrive (step S15: not) under the situation of cutting off end position, the operating motor control program, pulse is proofreaied and correct so that driving command umber of pulse P1 near actual number of drive pulses P2, and sends (step S16) to pulse motor 11 to driving command.Specifically, if the cloth C in the relative portion 50 with cutting knife of cutting knife 30 contact, then cutting knife 30 is subjected to cutting off resistance, so pulse motor 11 is not to move according to driving command pulse P1, and the decline of cutting knife 30 produces and postpones.In the case, rise, send and be corrected as the driving command pulse that makes pulse motor 11 temporary transient counter-rotatings in order to make cutting knife 30.Thus, the deviation between driving command umber of pulse P1 and the actual number of drive pulses P2 is diminished.After the processing of step S16, carry out the processing of step S13 once more.
On the other hand, in step S15, judge that cutting knife 30 arrives under the situation of cutting off end position (step S15: be), send the driving command pulse (step S17) that cutting knife 30 is risen to pulse motor 11.Specifically, under the situation that the driving pulse P2 and the mobile pulse b0 of reality equate, cloth C is run through in the lower end of cutting knife 30, is positioned at the position of the upper end butt of relative portion 50 with cutting knife.In the case, cutting knife 30 rises and gets back to origin position.
Then, if cutting knife 30 arrives origin position, then stop to send driving command pulse (step S18) to pulse motor 11, this processing so far finishes.
＜action effect 〉
According to buttonholing machine as noted above 1,, cutting knife 30 is moved by carry out the drive controlling of pulse motor 11 by CPU 71.When this moved, encoder 12 detected the driving pulse of the reality of pulse motor 11.CPU 71 is by carrying out the deviation calculation program, calculates from control device 7 to driving command pulse P1 that pulse motor 11 sends with by the deviation between the driving pulse P2 of the reality of encoder 12 detected pulse motors 11.Then, before the driving pulse P2 of reality surpasses the detection range umber of pulse c0 that is stored in the memory 72, the deviation that is calculated is above being stored under the situation of the contact detection deviation f0 in the memory 72, then CPU 71 judges that cutting knife 30 contacts with barrier, thereby the mobile of cutting knife 30 stopped.
Thus, if paired pulses motor 11 produces load because cutting knife 30 contacts with barrier, the delay of the driving pulse of the reality of pulse motor 11 becomes excessive, and the mobile of cutting knife 30 stopped, so can prevent the damage of cutting knife 30 or the relative portion 50 of cutting knife.
In addition, owing to can detect the existence of barrier by control device 7 and pulse motor 11, so need near cutting knife 30 or the relative portion 50 of cutting knife, not be provided for detecting the sensor of barrier, can not hinder operation, can detect barrier and do not increase components number.
In addition, owing to contact with barrier at cutting knife 30, after CPU 71 makes mobile the stopping of cutting knife 30, CPU 71 drives pulse motor 11, cutting knife 30 is moved to origin position,, can easily carry out the removal operation of barrier so can make cutting knife 30 leave barrier.
