A kind of computerized emboridering machine broken thread detector
Technical field
The utility model relates to a kind of computer embroidering machine checkout gear, especially a kind of computerized emboridering machine broken thread detector.
Background technology
Computer control embroidery machine usually the phenomenon that breaks can occur in embroidery, especially multi-head computerized control embroidery machine, because the embroidery position is many, it is particularly important that burn out detection seems.The general light pulse signal that adopts becomes the signal of telecommunication, by electronic circuit and computer control.The light pulse signal frequency is high more, and accuracy of detection is high more (Ling Mindu more height) just.But the light pulse signal frequency is too high, is prone to empty newspaper phenomenon again.
The utility model content
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of computerized emboridering machine broken thread detector of high precision and high sensitivity is provided.
The utility model solves the technical scheme that its technical problem adopts: this computerized emboridering machine broken thread detector, the wire-crossing wheel seat is held on the tension seat panel, the wire-crossing wheel installation shaft is passed wire-crossing wheel seat interstitial hole, wire-crossing wheel is fastened on the wire-crossing wheel installation shaft, in the fastening lenticular lenses of the other end of wire-crossing wheel installation shaft and keep lenticular lenses and wire-crossing wheel installation shaft axis normal; Guide rail is fastened on the tension seat panel, the optocoupler assembly is fastened on grating to be installed on the slide block, grating is installed slide block and is inserted in the guide-track groove and can freely slidably reciprocate along guide rail, and optocoupler limits bar and seamlessly inserts grating and install in the notch on the slide block and be fixed on the frame; Embroider line after thread tension disc comes out through the line hook outside around roll sleeve to wire-crossing wheel, again through tailor's tack to following thread tension disc.
Wire-crossing wheel of the present utility model is fastened on the wire-crossing wheel installation shaft with first screw, at the other end of wire-crossing wheel installation shaft with the fastening lenticular lenses of second screw.
Lenticular lenses of the present utility model is a circular steel disc, evenly is carved with one group of loophole on it, and the hole is a slotted hole, and the center of slotted hole overlaps in vertical direction with the light source center of optocoupler assembly.
The effect that the utility model is useful is: having selected suitable accuracy of detection, adopted 50 lenticular lenses with 100 two kinds of specifications to succeed respectively through test of many times, is a kind of burn out detection of high precision and high sensitivity and the device of reporting to the police.Along with colour changing, can carry out burn out detection with one group of optocoupler assembly to arbitrary work shank.And on same indicator lamp, report to the police and demonstration.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
This computerized emboridering machine broken thread detector described in the utility model, be applicable to 6 pins, 9 pins, 12 pins, 15 pin special utility tension seats, its structure is formed: tension seat panel 1, cross line hook 2, wire-crossing wheel seat 3, wire-crossing wheel 4 wire-crossing wheel installation shaft 5, cross tailor's tack 6, guide rail 7, first screw 8 adopts Cross Recess Head Screw M3X8 H type, second screw 9 adopts Cross Recess Head Screw M3X10 H type, grating is installed slide block 10, optocoupler assembly 11, lenticular lenses 12, optocoupler limits bar 13, tension seat back shroud 14 is seen shown in Figure 1, embroider line 15, toggle switch 16, indicator lamp 17, roll sleeve 18, roll sleeve nail 19 is seen shown in Figure 2, see shown in Figure 3.Lenticular lenses 12 is a circular steel disc, evenly is carved with 100 or 50 loopholes on it.The hole is a slotted hole, and the center of slotted hole overlaps in vertical direction with the light source center of optocoupler assembly 11.
As shown in Figure 1, wire-crossing wheel seat 3 is held on the tension seat panel 1, wire-crossing wheel installation shaft 5 is passed wire-crossing wheel seat 3 interstitial holes, and keep and in the hole, freely to rotate, wire-crossing wheel 4 usefulness Cross Recess Head Screw M3X8 H types 8 are fastened on the wire-crossing wheel installation shaft 5, at the other end of wire-crossing wheel installation shaft 5 with Cross Recess Head Screw M3X10 H type 9 fastening lenticular lenses 12 and keep lenticular lenses 12 and wire-crossing wheel installation shaft 5 axis normal.
Guide rail 7 usefulness countersunk head tapping screws are fastened on the tension seat panel 1, optocoupler assembly 11 usefulness countersunk head tapping screws are fastened on grating install on the slide block 10 (seeing shown in Figure 1), and grating is installed in slide block 10 insertion guide rails 7 grooves and can freely be slidably reciprocated along guide rail 7.Optocoupler limits bar 13 and seamlessly inserts grating and install in the notch on the slide block 10 and be fixed on the frame.See shown in Figure 1.
As shown in Figure 2, through enclosing around roll sleeve 18 to 3/4 of wire-crossing wheel 4 outside the line hook 2, process tailor's tack 6 is to following thread tension disc again after thread tension disc comes out for embroidery line 15.Embroider line and under the effect of thread tension disc up and down, be in tensioning state all the time.
Operation principle: along with the motion of embroidering pin, embroider line and dragged, under the frictional force effect between on-line tension and line and wire-crossing wheel, drive the wire-crossing wheel rotation equably, at this moment, lenticular lenses 12 rotation in optocoupler assembly 11 synchronously.Thereby reach the purpose that produces light pulse.By circuit optical signal is become the signal of telecommunication again and carry out computer control detection.Broken in case embroider line, wire-crossing wheel 4 has not changeed, and simultaneously, lenticular lenses 12 has also been stopped, and does not produce light pulse, and nature can't be transformed into the signal of telecommunication, does not have the signal of telecommunication, and electronic circuit is reacted at once and reported to the police and demonstration.Indicator lamp 17 becomes redness by green immediately and sees and shown in Figure 1ly see shown in Figure 2ly that during colour changing, tension seat panel 1 moves, and just guide rail 7 is installed slide block 10 along grating and moved.Each mobile 1/2 liang of wire-crossing wheel 4 centre distance, 11 alternations of two optocoupler assemblies promptly detect once up and down.Toggle switch 16 is used for this head work whether switching.Nature also is the switching that this head will not break and examine.
