Abstract

The utility model discloses an automatic warp stop device of a warp knitting machine. The automatic stop device comprises an air blower provided with a blowpipe, a PLC (programmable logic controller), and a photoelectric sensor provided with a light transmitting terminal and a receiving terminal; air outlet holes are formed on the blowpipe in the axial direction; the light transmitting terminal and the receiving terminal are oppositely arranged on two horizontal sides of warp; when knitted, the warp is positioned between light emitted from the light transmitting terminal of the photoelectric sensor and the air outlet holes of the blowpipe; the PLC is electrically connected with the photoelectric sensor and a main motor driving the warp knitting machine to knit respectively; and the photoelectric sensor can be an infrared photoelectric sensor. The device further comprises an alarm electrically connected with the PLC. When detecting broken warp, the automatic warp stop device can make a quick response automatically by stopping the warp knitting machine from knitting. The utility model has the advantages of extensive detection coverage and quick response, thereby effectively reducing the rejection rate. The automatic warp stop device is suitable for promotion and application in the warp knitting machine.

Description

Warp knitting machine warp break automatic stop arrangement
Technical field
The utility model relates to textile machine auto-stopper in a kind of field of textiles, particularly relates to textile machine in the braiding process, and when fracture took place yarn, textile machine can self-braking device.
Background technology
Existing twin shaft to, multiaxis to and warp knitting machine such as knit-stitch machine during in braiding, the warp thread space certain distance of One's name is legion is drawn from coiled hair or creel, entering knitting mechanism behind the process tension mechanisms etc. weaves, in this process, the overtension that is subjected to when warp thread or because of reasons such as sole masses, a small amount of warp thread usually ruptures in warp let-off process, and in case rupture, on the one hand, operating personnel are difficult to find, so greatly reduced fabric quality, on the other hand, even operating personnel have found fracture, but on the time period between warp thread generation fracture and the operating personnel's discovery, warp knitting machine is still remaining in operation, and has so often produced the part waste product, thereby has brought economic loss to enterprise.
The utility model content
The technical problems to be solved in the utility model provides a kind of warp knitting machine in the braiding process, the warp knitting machine warp break automatic stop arrangement that can in time shut down when in a single day warp thread fracture takes place.
For solving the problems of the technologies described above, the utility model adopts so a kind of warp knitting machine warp break automatic stop arrangement, and it comprises air blast, the Programmable Logic Controller PLC that blower is installed and has the light emission end and the photoelectric sensor of light receiving terminal; It axially offers some exhaust vents described blower upper edge, the light emission end of described photoelectric sensor and light receiving terminal relatively are arranged on the both lateral sides of described warp thread, in when braiding, described warp thread is between the exhaust vent of light that the light emission end of described photoelectric sensor is sent and described blower; Described Programmable Logic Controller PLC is respectively with described photoelectric sensor and drive the main motor that described warp knitting machine weaves and be electrically connected.
Described photoelectric sensor is preferably infrared photoelectric sensor.
After adopting said structure, because warp thread is between the exhaust vent of light that the light emission end of photoelectric sensor is sent and blower, thereby when braiding, when in a single day warp thread ruptures, its wind that is blown out by described exhaust vent by air blast immediately rises showy, at this moment, the light that is sent by the light emission end is sheltered from wherein a part of by the fracture warp thread that should float, thereby the luminous flux that projects the light receiving terminal is changed, the optical signal of the variation that photoelectric sensor will record converts the signal of telecommunication to and sends Programmable Logic Controller PLC to, controls main motor by Programmable Logic Controller PLC and in time shuts down.The warp thread distance that warp break automatic stop arrangement of the present utility model detects, the distance of detection can reach more than 10 meters, and the response time is short, can make warp knitting machine stop knitting automatically after the warp break immediately, thereby effectively reduce percent defective.
As a kind of improvement of the present utility model, this warp break automatic stop arrangement also is provided with an alarm that is electrically connected with described Programmable Logic Controller PLC.Such structure when fracture takes place warp thread, is sent chimes of doom immediately by Programmable Logic Controller PLC control alarm, can in time remind operating personnel that yarn is repaired like this, thereby enhance productivity.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of the utility model warp knitting machine warp break automatic stop arrangement.
The specific embodiment
Referring to a kind of warp knitting machine warp break automatic stop arrangement shown in Figure 1, comprise air blast 1, the Programmable Logic Controller PLC 2 that blower 1-1 is installed and have light emission end 3-1 and the photoelectric sensor 3 of light receiving terminal 3-2; It axially offers some exhaust vent 1-1-1 described blower 1-1 upper edge, the light emission end 3-1 of described photoelectric sensor 3 and light receiving terminal 3-2 relatively are arranged on the both lateral sides of described warp thread 4, in when braiding, described warp thread 4 is between the exhaust vent 1-1-1 of light 5 that the light emission end 3-1 of described photoelectric sensor 3 is sent and described blower 1-1; Described Programmable Logic Controller PLC 2 is respectively with described photoelectric sensor 3 and drive the main motor 6 that described warp knitting machine weaves and be electrically connected.Described air blast 1 is fixedly mounted on the frame of described warp knitting machine.
In the utility model, photoelectric sensor 3 is preferably infrared photoelectric sensor, also can be the ultraviolet electric transducer certainly; The light emission end 3-1 of this photoelectric sensor 3 and receiving terminal 3-2 are fixedly mounted on respectively on the frame of described warp knitting machine, and be not shown in the figures.
For when fracture takes place in warp thread 4, can in time remind operating personnel to repair or handle, thereby enhance productivity, this automatic stop arrangement also is provided with an alarm 7 that is electrically connected with described Programmable Logic Controller PLC 2, as shown in Figure 1, when fracture takes place warp thread 4, send chimes of doom immediately like this by Programmable Logic Controller PLC 2 control alarms 7.
Referring to Fig. 1, the course of work of the present utility model is as follows: when warp knitting machine normally weaves, the light 5 that is sent by the light emission end 3-1 of photoelectric sensor 3 is received by receiving terminal 3-2 fully, luminous flux does not change, at this moment, photoelectric sensor 3 converts the optical signal of normal flux to the signal of telecommunication and sends Programmable Logic Controller PLC 2 to, is run well by the main motor 6 of Programmable Logic Controller PLC 2 controls; When a certain warp thread 4 ruptures, it is risen showy by air blast 1 by the wind that described exhaust vent 1-1-1 blows out immediately, at this moment, the light 5 that is sent by light emission end 3-1 is sheltered from wherein a part of by the fracture warp thread 4 that should float, thereby the luminous flux that projects light receiving terminal 3-2 is changed, the optical signal of the variation that photoelectric sensor 3 will record converts the signal of telecommunication to and sends Programmable Logic Controller PLC 2 to, the main motor 6 that is woven by Programmable Logic Controller PLC 2 control driving warp knitting machines in time shuts down, thereby reaches the purpose of warp break automatic stop.
