Abstract
The utility model relates to a device used for identifying the weft breaking location when weft breaks on a rapier loom. Currently, the weft breaking location cannot be determined, and the reasons for weft breaking cannot be analyzed. In the utility model, a signal output end of a weft detector arranged at the weft guiding mouth is connected with a signal input end of an electrical level transfer circuit; the signal output end of the electrical level transfer circuit is connected with the signal input end of an A/D transformer; the signal output end of the rotary encoder, at which the A/D transformer is matched and connected with the main shaft, is connected with the signal input end of a DSP processor chip; and a display is connected with the signal of the DSP processor chip. By using the utility model, in the event of weft breaking, the DSP processor chip can record the corresponding angle signals of the main shaft when the weft tension signal changes, and the display shows the weft breaking location as well.
Description
Technical field
The utility model belongs to field of textile machinery, relates to a kind of device of the staplings position when being used to discern the Rapier looms staplings.
Background technology
The wefting insertion process of Rapier looms is comparatively complicated, is difficult to observe the wefting insertion process when running up.Introduce weft yarn from weft-sending sword head and insert weft yarn, after last weft-recepting sword head is moved weft yarn to certain position weft yarn is unclamped to weft-recepting sword head.In two reciprocating whole processes of sword head, weft yarn is disconnected, by the variation of weft detector voltage signal, the control Rapier looms stops.Stop the back by automatic latitude seeking, the weft yarn that disconnects is pulled out from fell, drive again after again weft yarn being connected.At present, the position of staplings can't be determined, can not analyze targetedly the reason of staplings, also can't reduce the staplings phenomenon to Rapier looms adjustment by analyzing the staplings position.
Summary of the invention
The purpose of this utility model is to solve problems of the prior art, and the recognition device of a kind of Rapier looms staplings position is provided.
The utility model comprises weft detector, level shifting circuit, A/D converter, dsp processor chip, rotary encoder and display.Weft detector is installed in the rapier loom weft insertion mouth, and the main shaft of rotary encoder and Rapier looms is connected.The signal output part of weft detector is connected with the signal input part of level shifting circuit, the signal output part of level shifting circuit is connected with the signal input part of A/D converter, the signal output part of A/D converter and rotary encoder is connected with the signal input part of dsp processor chip, and display is connected with the dsp processor chip signal.
Weft detector and rotary encoder adopt the corresponding component of existing Rapier looms, level shifting circuit, A/D converter, dsp processor chip adopt ripe prior art, adopt the AD ADC1143 of company A/D converter as A/D converter, the dsp processor chip adopts the TMS320280 processor chips of TIX.
Adopt Rapier looms staplings position identification device of the present utility model, if generation staplings, the angle signal of the main shaft of correspondence when the tension signal that the dsp processor chip will write down weft yarn changes, and on display, demonstrate the position of staplings, just can know which stage generation staplings is in, and then can determine to cause the reason of staplings.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, Rapier looms staplings position identification device comprises weft detector 1, level shifting circuit 2, A/D converter 3, dsp processor chip 4, rotary encoder 6 and display 5.Weft detector 1 is installed in the rapier loom weft insertion mouth, and rotary encoder 6 is connected with the main shaft of Rapier looms.The signal output part of weft detector 1 is connected with the signal input part of level shifting circuit 2, the signal output part of level shifting circuit 2 is connected with the signal input part of A/D converter 3, the signal output part of A/D converter 3 and rotary encoder 6 is connected with the signal input part of dsp processor chip 4, and display 5 is connected with dsp processor chip 4 signals.
Weft detector is as external sensor output weft tension signal, and tension signal voltage is 0～12V.Level shifting circuit can carry out voltage transitions, is 0～1V with the tension signal voltage transitions.A/D converter converts voltage signal to data signal input dsp processor chip.Rotary encoder converts the rotary angle signal of rapier loom main shaft to data signal, input dsp processor chip.The dsp processor chip carries out alignment processing with the tension signal of weft yarn and the angle signal of main shaft.If generation staplings, the tension signal of weft yarn changes, the angle signal of the main shaft of correspondence when dsp processor chip tracer signal changes, and on display, demonstrate the position of staplings, just can know which stage generation staplings is in, and then determine to cause the reason of staplings.So just can effectively adjust Rapier looms, so that reduce the generation of staplings phenomenon later on.
A/D converter of the present utility model adopts 16 bit resolutions, can tell 1/65535 (0.00153%) of full scale, and A/D conversion time is 80us, A/D converter transformed error≤± 0.06%.
