In making technical ability decision maker 1,, in the display part 21 of guidance panel 20, carry out the demonstration of various curve maps by the technical ability decision procedure.
(the technical ability determination processing of being undertaken by the technical ability decision procedure)
Below, the contents processing that is undertaken by above-mentioned technical ability decision procedure is described.In addition, below Shuo Ming processing, all carrying out with the CPU 11a by the control device 11 of carrying out the technical ability decision procedure is that prerequisite describes.
As noted above, in making, make operation for one, from make beginning till finish during obtain the sewing speed data, these sewing speed data obtain being sampled by spindle encoder 16 detected sewing speeds every the unit interval of regulation.Fig. 3 is that expression is with 0.5[s] be that unit is to sewing speed V[rpm] chart of the content of the sewing speed data that obtain detected, Fig. 4 is that transverse axis is from making the elapsed time t of beginning, the longitudinal axis is sewing speed V, the actual measured value curve map J of expression sewing speed data.
After making, the sewing speed data of storing among the EEPROM 11d, be in the state that to arrange chronologically every detected sewing speed of unit interval, but CPU 11a will sort according to descending (descending order) every detected sewing speed of unit interval, and newly-generated conversion sewing speed data.Fig. 5 is the chart of the content of expression conversion sewing speed data, and Fig. 6 is that transverse axis is time t, and the longitudinal axis is sewing speed V, based on the contrast curve map H of the conversion sewing speed data of sewing speed being arranged with the order after the ordering.
In actual measured value curve map J, owing to be actual measured value, so produce the increase and decrease of sewing speed at random, but use among the curve map H in contrast, owing to sort according to sewing speed, so curve map becomes the shape on the slope that merely descends.
In addition, because conversion sewing speed data sort according to sewing speed, so can obtain making in the operation once, how long to make, that is, the working time of each sewing speed distributes for each sewing speed.
And the working time of this each sewing speed distributes, and along with operators'skills uprises, the shared time scale of high speed becomes many and the shared time scale step-down of low speed.In addition, if operators'skills is low, then on the contrary, it is many that the time scale that the shared time scale of high speed tails off and low speed is shared becomes.
In addition, make technical ability decision maker 1 and be conceived to the characteristic of this conversion sewing speed data, conversion sewing speed data after the ordering are divided into a plurality of intervals (being 4 intervals in the present embodiment) equably on time shaft, obtain the mean value of each interval sewing speed and poor between each interval predefined datum velocity, corresponding with difference and determine mark, and obtain the aggregate value of each interval mark, with the evaluation of estimate of this aggregate value as operating personnel's technical ability.
Based on Fig. 7, record and narrate the processing that technical ability is judged in detail here.Fig. 7 is with the key diagram of contrast with the curve map H quartern.
At first, as noted above, for conversion sewing speed data, with the whole quartern of its working time.At this moment, no matter the total of working time is long still short, all carries out five equilibrium with predetermined interval quantity.
The dash area of Fig. 7 represents that to the zone after the averaging of sewing speed of the time per unit among each interval A1～A4 the dotted line of its upper end is represented mean value.In addition, the dot-and-dash line shown in each interval A1～A4 is represented the datum velocity in this interval.In other words datum velocity in each interval, is each interval target sewing speed, if the mean value of the sewing speed of actual measurement in each interval does not reach datum velocity, then evaluation of estimate subtracts branch, if reach then bonus point.
Preferred said reference speed is made operation at each and is prepared respectively.
In addition, the preferred datum velocity in each interval, with interval that average velocity is high and set highly more as prerequisite, and maybe this makes the difficulty of operation and determines concrete numerical value according to statistical thumb rule for example.For example, if the many operations of straight line stitching, then each interval datum velocity is set higherly, is comprising curvilinear stitching or is changing direction and making of carrying out, the situation of making that other need the time are inferior, and each interval benchmark is set lowlyer.In addition, datum velocity also can at random be set by operating switch 13.
Then, if obtain the poor of datum velocity and average velocity, then determine with respect to each interval difference and predefined mark at each interval.Fig. 8 is the table of the relation of expression velocity contrast and mark, and this score graph is stored in the EEPROM 11d.
As shown, the relation between velocity contrast and the mark is set at, and along with velocity contrast becomes big, it is big that mark also becomes.
Then, determine the mark that each is interval, and calculate their aggregate value, be presented on the display part 21 as evaluation of estimate (evaluation level).In addition, the high more certain expression technical ability of this evaluation of estimate is high more.
Based on the process flow diagram of Fig. 9, illustrate in greater detail the processing of above-mentioned technical ability decision procedure.
At first, if the operation of the pedal 8 by sewing machine main body 10 begins to make, then control device 11 is till sewing finishing, receives the output of spindle encoder 16 repeatedly with the sampling interval of regulation (0.5[S]), and CPU 11a generates sewing speed data (with reference to Fig. 3) (step S11).By above-mentioned processing, CPU 11a works as " the sewing speed data obtain the unit ".In addition, the end of making can be judged according to pedal sensor 17, also the tangent line indication input of being undertaken by pedal operation can be considered as finishing.In addition, also can on control device 11 or guidance panel 20, be provided for importing the counter switch of sewing finishing.
Then,, then will sort newly-generated conversion sewing speed data (with reference to Fig. 5) (step S 12) every detected sewing speed of unit interval if obtain the sewing speed data according to descending.By above-mentioned processing, CPU 11a works as " data conversion unit ".
Then, CPU 11a is graphical with the sewing speed of each unit interval in the conversion sewing speed data, generates contrast and uses curve map H, utilizes display part 21 to show (step S13).
Then, will contrast the quartern on time shaft (step S14) with curve map H (conversion sewing speed data).
Then, begin the mean value (step S15) of the sewing speed the computation interval successively from interval A1.Then, from the average velocity of obtaining, deduct interval datum velocity, with this subtraction value accordingly, with reference to the table of the relation of expression velocity contrast and mark, determine mark (step S16).
Then, at all interval A1～A4, carry out the processing of above-mentioned steps S15, S16 repeatedly.
Then, CPU 11a adds up to mark, and the result that will estimate as technical ability based on the respective horizontal of this aggregate value is presented at (step S17) on the display part 21.By the processing of step S14～S17, CPU 11a works as " identifying unit ".
(effect of first embodiment)
As noted above, making in the technical ability decision maker 1 of sewing machine, obtain the variation of sewing speed chronologically by actual measurement, as the sewing speed data, then will be every detected sewing speed of unit interval, order according to this sewing speed sorts, and obtains conversion sewing speed data and contrast curve map.Then, because the datum curve figure (perhaps reference data) that will contrast with curve map (perhaps conversion sewing speed data) and each level compares, carry out determining of respective horizontal according to the minimum curve map of difference, so can carry out the judgement of technical ability based on numerical value, therefore, can can not judge technical ability objectively because of the evaluation personnel produce bias.
(second embodiment)
Below, second embodiment is described.In the present embodiment, utilize and the above-mentioned technical ability decision maker 1 identical structure on hardware of making, use the technical ability decision procedure that carries out other the technical ability determination processing different with above-mentioned technical ability determination processing.Therefore, the explanation of omitting sewing machine main body 10, guidance panel 20 and making technical ability decision maker 1 only mainly describes its technical ability decision method and contents processing thereof.
As noted above, in making, make operation for one, from make beginning till finish during obtain the sewing speed data, these sewing speed data are that the sewing speed by the unit interval that utilizes spindle encoder 16 detected every regulations constitutes, based on these sewing speed data, CPU 11a will sort according to descending (descending order) every detected sewing speed of unit interval, and generate conversion sewing speed data H (with reference to Fig. 5,6).
Then, make technical ability decision maker 1 and in EEPROM 11d, prepare the data of horizontal data and horizontal line graph (benchmark) K in advance, this horizontal data is the reference data by each level of skill of grade classification level, and this horizontal line graph (benchmark) K is the datum curve figure corresponding with horizontal data.Figure 10 (A)～(F) is the example with respect to the horizontal line graph K of each level.In addition, this reference data and each datum curve diagram data, the data that generate by actual measurement in the time of can utilizing technical ability is different in practice each operating personnel to make also can be according to being generated by the resulting tendency of the statistics in past.In addition, EEPROM 11d works as " storage unit " thus.
In addition, the setup unit of setting arbitrarily for the data (sample data) of the horizontal line graph K of each level (for example, touch-screen 23) can be set, generate, also can be kept among the EEPROM 11d as storage unit by setting input.
Then, the conversion sewing speed data that will obtain by actual measurement (perhaps contrast curve map H), and each reference data (perhaps each datum curve figure K) by the technical ability of grade classification level contrast, calculate departure each other, obtain the level of departure minimum, this level is judged to be operators'skills.
In addition, reference data and datum curve figure K preferably for the identical thing of making when obtaining the conversion sewing speed data that compare and contrast with curve map H, carry out the identical data of making sewing procedure and obtaining.
Record and narrate the calculating of above-mentioned departure here, in detail.Figure 11 will contrast the key diagram of the departure calculating of using curve map H and datum curve figure K (level 4) to overlap and representing.
Shown in the dash area of Figure 11, contrast is calculated as departure with respect to the area summation of the non-coincidence part of datum curve figure K with curve map H.The area summation of non-coincidence part for example by obtaining the area difference with the small time width of each curve map time shaft five equilibrium, and adds up to and calculates it.In the case, no matter contrast and be higher than datum curve figure K with curve map H and still be lower than datum curve figure K, all calculate, do not import positive and negative notion as positive deviate.
In addition, as noted above, according to each data formation curve figure, obtain deviate according to its area, but also can replace this mode, as shown in figure 12, according to conversion sewing speed data and reference data, obtain the absolute value of the difference of the sewing speed under the identical time respectively, and calculate their aggregate value.
Then, calculate, the level of departure minimum is defined as these operating personnel's respective horizontal with respect to the reference data of each level or the departure of datum curve figure.
Based on the process flow diagram of Figure 13, illustrate in greater detail the processing of above-mentioned technical ability decision procedure.
At first, if the operation of the pedal 8 by sewing machine main body 10 begins to make, then control device 11 is till sewing finishing, receive the output of spindle encoder 16 repeatedly with the sampling interval (0.5[S]) of regulation, CPU 11a generates sewing speed data (with reference to Fig. 3) (step S31: " the sewing speed data obtain the unit ").In addition, the end of making can be judged according to pedal sensor 17, also the tangent line indication input of being undertaken by pedal operation can be considered as finishing.In addition, also can on control device 11 or guidance panel 20, be provided for importing the counter switch of sewing finishing.
Then,, then will sort newly-generated conversion sewing speed data (with reference to Fig. 5) (step S32: " data conversion unit ") every detected sewing speed of unit interval according to descending if obtain the sewing speed data.
In addition, CPU 11a is graphical with the sewing speed of each unit interval in the conversion sewing speed data, generates contrast and uses curve map H, utilizes display part 21 to show (step S33).
Then, successively datum curve figure K is overlapped (step S34) with contrast with curve map H, calculate the area summation of non-coincidence part, temporarily be stored in (step S35) among the RAM 11b from level 1 beginning.Then, the datum curve figure K at all levels carries out the processing of above-mentioned steps S34, S35 repeatedly.
Then, the area total value with respect to the non-coincidence part of each level of CPU 11a in RAM 11b, the retrieval minimum value based on the datum curve figure corresponding with minimum value, and is determined level (step S36).
Then, the result that CPU 11a estimates as technical ability is presented at (step S37) on the display part 21 with respective horizontal.By the processing of step S33～S37, CPU 11a works as " identifying unit ".
(effect of second embodiment)
