Description
Technical field
It the utility model is related to a kind of rotating shuttle assembly.
The utility model further relates to a kind of bobbin thread for sewing machine allowance detector for including above-mentioned rotating shuttle assembly.
Background technology
Sewing machine is with one or more sewing thread, and one or more stitchings are formed on fabric, make one or more layers face
The machine that material interweaves or unites by a seam.When sewing fabric, the rotating shuttle and eedle of sewing machine cooperate with by bottom line sewing machine
Lock-stitch is interleaved with each other on fabric with upper thread, so as to form stitching.Upper thread is threaded through in the pinprick of eedle, and eedle is done
Rise, descending motion；Rotating shuttle is made of bobbin case and peg or spindle, and peg or spindle is housed in bobbin case, and bottom line is wrapped on peg or spindle.Upper thread is general
It is longer, there is 3000m-4000m, and user can observe the number of upper thread line amount at any time in sewing process, therefore face can be replaced in time
Line.But due to the limitation of sewing machine space and mechanism principle, bottom line is generally shorter, only 20m-50m, therefore in sewing process
In need to be replaced as frequently as bottom line, do not found yet if being used up when bottom line, sky can occur and step on, and then pin hole is produced on cloth,
Cause the waste of precious cloth and increase the labor intensity that worker does over again.
Thus, bobbin thread for sewing machine allowance detector is generated, it is whether insufficient for detecting bottom line surplus on peg or spindle.Mesh
Before, bobbin thread for sewing machine allowance detector is mainly had two kinds of counting mode and hop mode, the seam of counting mode by testing principle
Machine bottom line allowance detector of threading refers to the Chinese invention patent application specification of Application No. 201310278156.1, saltus step

Bright book；But existing bobbin thread for sewing machine allowance detector all there are it is certain the drawbacks of.
First, in the bobbin thread for sewing machine allowance detector of counting mode：1st, due to some situations, it is necessary to artificially remove part
Bottom line, then it is None- identified that the above situation is automatically controlled, automatically controlled record be still initial coiling record data, therefore final knot
Fruit will cause actual used up of bottom line and automatically controlled can not be detected, will not alarm.2nd, for different peg or spindles, it identifies accurate
Rate can not ensure 100%, and short distance sewing None- identified peg or spindle：Because peg or spindle identification is the accounting time according to low and high level
Foundation is judged, that is, the black region on peg or spindle flange surface and white area residence time reduced value；
In order to accurately identify judgement peg or spindle, during signal generation, black and the speed that white area passes through must be even on peg or spindle
Speed, and sewing machine acts the last lap that peg or spindle rotates when the first lap that peg or spindle rotates when stitching is shut down with sewing machine, its speed is simultaneously
It is non-at the uniform velocity, that several circle only among sewing process are at the uniform velocity, so peg or spindle must turn 3 circles and could identify in theory, and to expire
The length of 3 circle bobbin threads be more than 15cm under wire state, therefore when the operating mode that sew is 5cm, when 7cm, peg or spindle is with regard to nothing
Method identifies that is, enabled, the recognition accuracy of peg or spindle can not also ensure, so as to can not just guarantee to detect exactly more than bottom line
Amount.
2nd, in the bobbin thread for sewing machine allowance detector of hop mode：1st, for the different bottom line of thickness, remaining line amount without
Method is consistent：Since hop mode is using interlayer peg or spindle, when line to bottom with interlayer is skipped to, machine report after mutation is produced
It is alert, and the capacity of interlayer is certain, therefore for the line coiling amount of different thicknesses, the remaining remaining line length of bottom line of different thicknesses
Degree can not be consistent.2nd, easily produce wrong report and fail to report problem：A, because the interlayer of interlayer peg or spindle there are certain height with roll
Difference, when small roll bottom line is used up, the bottom line on interlayer is easily slid to small roll, is caused a kind of conversion relations, is kept away
Mutation has been opened, has caused to fail to report；B, for big needle distance situation because the relatively small needle gage of the line of a pin is more, therefore saltus step this
At time point, the corresponding pin number change of a circle shuttle thread is not clearly, not reach alarming value, can produce yet and fail to report, to avoid this
One situation is failed to report, and is usually solved with reduction alarming value, but can not be met in normal sewing process again after reducing alarming value
Caused by, data fluctuations and cause to report by mistake；C, in winding process, bottom line easily produced at interlayer and roll coiling it is bad,
The phenomenon of coiling confusion, and then wrong report is easily produced in use.
In conclusion bobbin thread for sewing machine allowance detector of the prior art is in actual use, bottom line surplus
The precision of detection is not still very high.
