Description
Technical field
The utility model relates to a kind of weft stop detecting devices more particularly to a kind of for there is the digital photoelectricity of woven fabric machine
Weft stop detecting device, belonging to has woven fabric machine technical field.
Background technique
There is woven fabric machine detection staplings to mostly use to select greatly and peck formula (also known as chicken pecks rice) latitude and stop detection device at present, which is
It is mechanical, there is a sets of transmission mechanism, installation and debugging require high, high failure rate, and shortcoming is specific as follows:
1, when weaving extra-high yarn count high density fabric, needle path, pinprick fault are apparent.
2, feeler motion structure is prone to wear, and feeler need to be frequently inserted at cloth cover fell, when moving abnormal, is easy
Fault-free is caused to shut down.
3, structure is complicated for feeler motion, and reliability is low.When its failure, feeler skew, burr hangs yarn, is easy to appear double weft
Or centipede.
4, feeler motion adjustment difficulty is big.Point pecks the fell weft yarn of steel needle, fastener (chicken head) component and steel needle insertion cloth cover
Depth, need to depending on kind difference and do corresponding adjustment, otherwise easily cause mistakenly stop or leakage to stop, it is higher that mistakenly stop or leakage stop platform rate,
It can account for always stopping 30% or more of platform.
5, feeler motion is troublesome in poeration, when upper axis, dismounting badly cloth operation, first to remove and a little peck steel needle, to the end of operating, then
Again point is pecked into steel needle and original position is installed back.
Utility model content
The technical problems to be solved in the utility model is against the above deficiency, to provide a kind of for there is the number of woven fabric machine
Formula photoelectricity weft stop detecting device, which is electronic type, contactless with weft yarn, can effectively reduce therefore stop or leak the rate of stopping, and
Prevent needle path appearance；Not only precision is high for the utility model, high reliablity, but also structure is simple, easy for installation, and it is various to adapt to weaving
Fabric.
In order to solve the above technical problems, the technical solution adopted in the utility model is as follows: one kind is for there is woven fabric machine
Digital photoelectricity weft stop detecting device, including photoelectric sensor, photoelectric sensor has reception pipe and transmitting tube, reception pipe electricity
It is connected with reception circuit, transmitting tube is electrically connected with modulation drive circuit, receives circuit and modulation drive circuit has been electrically connected
MCU, MCU have been electrically connected power supply, driving circuit, and driving circuit is electrically connected with loom controller.
As a further improvement of the above technical scheme:
The photoelectric sensor is arranged on sliding bar, and sliding bar is arranged in mounting seat.
The side of the mounting seat be equipped with guiding slide bar, guiding slide bar be equipped with guide fixed block, guide fixed block with
Tension spring is equipped between mounting seat.
The lower section of the photoelectric sensor side is equipped with signal wire, and signal wire is connected with loom controller.
The top of the photoelectric sensor side is equipped with power switch.
The utility model takes above technical scheme, has the advantage that
1, the present apparatus is, no abrasion contactless with weft yarn, can effectively reduce therefore stop or leak the rate of stopping, thoroughly avoid the occurrence of needle
Road, pinprick fault.
2, present apparatus precision is high, high reliablity, the utility model be it is intellectual, without adjustment, calculate loom automatically
Revolving speed, normal wefting insertion when technological parameter, precision and reliability are unrelated with yarn count and speed, automatic to adapt to weave various yarns
Branch fabric.
3, present apparatus structure is simple, easy to operate, when upper axis, dismounting badly cloth, without operation, improves work efficiency.
The utility model is described in further detail with reference to the accompanying drawings and examples.

Specific embodiment
Embodiment, it is as shown in Figure 1 and Figure 2, a kind of for there is the digital photoelectricity weft stop detecting device of woven fabric machine,
Including photoelectric sensor 6, photoelectric sensor 6 has reception pipe 9 and transmitting tube 10, and reception pipe 9, which is electrically connected with, receives circuit 12, hair
It penetrates pipe 10 and is electrically connected with modulation drive circuit 11, receive circuit 12 and modulation drive circuit 11 has been electrically connected MCU13,
MCU13 has been electrically connected power supply 15, driving circuit 14, and driving circuit 14 is connected with loom controller.
The top of 6 side of photoelectric sensor is equipped with power switch 7, and the lower section of 6 side of photoelectric sensor is equipped with signal wire 8,
Signal wire 8 is connected with loom controller, and photoelectric sensor 6 is arranged on sliding bar 5, and sliding bar 5 is arranged in mounting seat 1,
The side of mounting seat 1 is equipped with guiding slide bar 2, and guiding slide bar 2 is equipped with guide fixed block 3, guide fixed block 3 and mounting seat
Tension spring 4 is equipped between 1.
Using to spy latitude mode is penetrated, pulse signal is generated by MCU, drives infrared transmitting tube after modulated, amplification, and by it
The infrared pulse that frequency is 80KHz is issued, the signal that infrared ray adopter receives is filtered, puts by operational amplifier
Greatly, shaping is sent to MCU, and MCU calculates the technological parameter when revolving speed of loom, normal wefting insertion automatically, judges that weft yarn is quiet accordingly
Only state or motion state then illustrate that weft yarn has broken, and issues filling broken signal immediately if not being motion state, allow loom
Main controller positions shutdown immediately.
