Number in the figure illustrates: 1, socket, 2, slim nut, 3, photoelectric tube 4. lens pillar, and 5. shadow shield, 6, luminous tube, 7. housing, 8, reflecting plate, 9, bottom line, 10, sewing machine table, 11, shuttle.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Shown in Fig. 3, a kind of broken thread detector, is arranged on bottom line 9 side between sewing machine table 10 and shuttle 11, comprise reflecting plate 8, described reflecting plate 8 is horizontal n shape, the reflecting plate 8 that upper plane A, lower plane B are parallel, and sidepiece is fixed on sewing machine frame.The upper plane A of described reflecting plate 8 is parallel with described bottom line 9, the lower plane B of reflecting plate 8 is connected with housing 7 by slim nut 2, luminous tube 6 and photoelectric tube 3 is provided with in described housing 7, and separated by a shadow shield 5, lens pillar 4 is respectively equipped with before described luminous tube 6 and photoelectric tube 3, described lens pillar 4 is semicylindrical lenses of single focal line, and the focal line of two pieces of lens pillars 4 on the same line.Be connected with socket 1 bottom described luminous tube 6 and photoelectric tube 3, described bottom line 9 is positioned at described luminous tube 6 and photoelectric tube 3 side.
Socket 1 is a four-core socket, and four pin of its upper end weld with the pin of luminous tube 6 and photoelectric tube 3 respectively, and four core plugs can be plugged in its lower end, and four core plugs are connected with circuit board.Photoelectric tube 3 is that the optical signal received is converted to the signal of telecommunication, exports the signal of telecommunication, and be input to circuit board by four core plugs by two lines of four-core socket.Luminous tube 6 is followed that circuit board is connected by four-core socket with another two lines of plug and obtains power supply.Lens pillar 4 has two pieces, and be arranged on respectively before luminous tube 6 and photoelectric tube 3, the focal line of two pieces of lens pillars must be on the same line.Shadow shield 5 is the centres being interposed between two pieces of lens pillars 4, and its effect is that the light blocking luminous tube 6 transmitting shines directly on photoelectric tube 3, and positions luminous tube 6 and photoelectric tube 3, makes to set a setting angle to luminous tube 6 and photoelectric tube 3.Housing 7 epoxy resin manufactures, and it is fixing lens pillar 4, luminous tube 6, photoelectric tube 3, shadow shield 5 and socket 1.
The A face of reflecting plate 8 is that beam reflection that luminous tube 6 is launched is to photoelectric tube 3 li.Thread break detector is with the B face of slim nut 2 fixation reflex plate 8.The A face of reflecting plate 8 must be parallel with B face.Reflecting plate 8 is fixed in the frame of Sewing machines by the securing member such as bolt, spring washer.
During the circuit ON of luminous tube 6, the light that luminous tube is launched is become band by lens pillar 4 pack, forms the bottom line searchlighting region of required length and width.Adopt this spline structure, can reach and just can obtain required large intensity of illumination with little luminous flux, so just can improve detection accuracy.
Broken thread detector is mounted between sewing machine table 10 and shuttle 11, and bottom line 9 is parallel with A face, and that is bottom line 9 is parallel with the focal line of lens pillar 4.Focal line, after collinear two pieces of lens pillars 4, distinguishes device luminous tube 6 and photoelectric tube 3.The main shaft of Sewing machines when 170-190 spends, the circuit ON of luminous tube 6, the light that at this moment luminous tube 6 is launched is become band by lens pillar 4 pack, in the path that bottom line 9 moves, form the bottom line 9 searchlighting region of required length and width band shape; Pass through another block lens pillar 4 by the reverberation of bottom line 9 simultaneously, effectively carry out optically focused, make photoelectric tube 3 obtain required luminous flux.Photoelectric tube 3 converts the signal of telecommunication to optical signal and exports, and is input to circuit board by holding wire.Input the signal of telecommunication through shaping, amplification and comparison circuit determine whether export executive signal.
Luminous tube 6 is bulb or semiconductor light-emitting-diode etc., element that namely can be luminous after energising.
Photoelectric tube 3 is phototransistor, light-sensitive element etc., light quantity can be transformed into the element of electricity.
During normal work, photoelectric tube 3 obtains reflecting plate 8 simultaneously and bottom line 9 reflects the light of coming, and optical signal is converted to signal of telecommunication output, is input to circuit board by holding wire; When bottom line 9 ruptures, photoelectric tube 3 acquisition reflecting plates 8 reflect the light of coming, and photoelectric tube 3 converts telecommunications to optical signal and is also input to circuit board by holding wire.Because the luminous flux of two kinds of situations also exists difference, can be differentiated by the comparison circuit of circuit board.Like this, when normal work, control circuit does not export executive signal; When breaking, circuit exports executive signal, and Sewing machines is stopped at once.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
