Abstract
The utility model relates to a fault detection device for a knitting needle of a computerized flat knitting machine. The fault detection device comprises a head of the computerized flat knitting machine, a needle-shaped probe is arranged on one side facing a needle plate on the head and horizontally arranged on the plate surface facing the needle plate on the head, the length direction of the probe is perpendicular to the head reciprocation direction, the probe is a touch sensor (such as the resistance type), and the probe is electrically connected with a controller and inputs electrical signals into the controller. The fault detection device has the advantages that faults (such as needle breakage and upwarp) of the knitting needle of the computerized flat knitting machine can be detected automatically and timely, signals can be sounded in time, a control system makes handling instructions to urge a concerned person to handle timely, effects on quality of textiles can be avoided, and chain accidents and great losses can be avoided; and the fault detection device is reliable in operation, simple in structure and convenient to implement.
Description
Technical field
The utility model relates to computer flat-bed knitting machine, espespecially a kind of knitting needle fault-locating unit of computer flat-bed knitting machine.
Background technology
The computer flat-bed knitting machine sector application of weaving cotton cloth is very wide.
Figure 1 shows that the front-view schematic diagram of existing computer flat-bed knitting machine 10.The board top is provided with a triangle needle-bar 11 that tilts forward and back, on the anteversion and retroversion inclined-plane of needle-bar 11, be respectively equipped with a needle plate 12, other is provided with a head 13 that can move back and forth along needle plate 12, head 13 is provided with programme controlled mountain panel assembly towards a side of needle plate 12, with knitting needle 15 displacements on the programming action control needle plate 12.Fig. 2 is needle plate 12 partial perspective views, what this needle plate 12 was provided with a plurality of upper downward-extensions rolls ditch 14, be respectively equipped with a knitting needle 15 in respectively rolling ditch 14, each knitting needle 15 is provided with an outstanding stitch 16, and this stitch 16 that protrudes from needle plate 12 surfaces is controlled its displacement by the mountain panel assembly.
Yet because the knitting needle translational speed of the automatic horizontal volume machine of computer is exceedingly fast, the yarn idol has the situations such as knotting again, and the excessive phenomenon of the failure of fracture that causes of knitting needle 15 loads is happened occasionally.Knitting needle 15 easily produces fatigue simultaneously, causes knitting needle 15 to upwarp.Knitting needle 36 fracture or to upwarp be knitting needle 15 operating most common failures, they can have a strong impact on the quality of fabric, even can cause stuck and can't operation, cause a series of accidents etc.The key of problem is, in time find these faults.Only have in time this type of fault, could in time process, unlikelyly cause large accident.
The utility model content
The utility model is intended to overcome the above-mentioned deficiency of prior art, releases a kind of knitting needle fault-locating unit of computer flat-bed knitting machine.Can automatically in time survey the knitting needle fault of computer flat-bed knitting machine, in time send signal, make the disposal instruction by control system, impel party person in time to process, avoid affecting the fabric quality, avoid causing a chain of accident, result in greater loss.
For solving its technical problem, the utility model adopts following technical scheme:
Construct a kind of knitting needle fault-locating unit of computer flat-bed knitting machine, the head that comprises computer flat-bed knitting machine, towards needle plate one side probe is set on the described head, described probe is a spicule, described probe is sleeping to be located at head on the plate face of needle plate, and the perpendicular direction of the length direction of described probe and the reciprocal walking of head.
Technique scheme is further set forth:
Described probe is a feeler.
Described probe is a resistor-type feeler.
Described probe is electrically connected with controller and to the controller input electrical signal.
Working mechanism of the present utility model is: the knitting needle of computer flat-bed knitting machine fracture or when upwarping; can stretch out the space from needle plate; contact with the probe on operating head just; described probe is a feeler (as resistive type); can make the probe conducting and produce the signal of telecommunication; the signal of telecommunication reaches control system; control system will be made shutdown immediately or other disposes instruction targetedly; so that being ruptured or upwarp immediately, disposes knitting needle; avoid affecting the fabric quality, avoid causing a chain of accident.
The utility model is compared with prior art, its beneficial effect is: one, can automatically in time survey the knitting needle fault (such as broken needle or upwarp) of computer flat-bed knitting machine, in time send signal, make the disposal instruction by control system, impel party person in time to process, avoid affecting the fabric quality, avoid causing a chain of accident, result in greater loss.Its two, reliable operation.Its three, simple in structure, be convenient to implement.
Description of drawings
Fig. 1 is the front-view schematic diagram of prior art computer flat-bed knitting machine;
Fig. 2 is needle plate and the knitting needle partial exploded view of prior art computer flat-bed knitting machine;
Fig. 3 the utility model schematic diagram.
Among the figure: 10, computer flat-bed knitting machine; 11, needle-bar; 12, needle plate; 13, head; 14, roll ditch; 15, knitting needle; 16, stitch; 17, probe.
The specific embodiment
Below, by reference to the accompanying drawings, introduce the specific embodiment of the present utility model.
As shown in Figure 3, the utility model is constructed a kind of knitting needle fault-locating unit of computer flat-bed knitting machine, the head 13 that comprises computer flat-bed knitting machine 10, towards needle plate 12 1 sides probe 17 is set on the described head 13, described probe 17 crouches and is located at head 13 on the plate face of needle plate 12, and the length direction of described probe 17 and head 13 be the perpendicular direction of walking back and forth, like this, probe 17 is along with head 13 is back and forth walked, the probe 17 back and forth formation scopes of walking has comprised the scope at all knitting needle 15 places, and all knitting needles 15 are all in the scope of the monitoring of probe 17.
Described probe 17 is a feeler, such as resistor-type.
Knitting needle 15 fracture of computer flat-bed knitting machine 10 or when upwarping; can stretch out the space from needle plate 12; contact with the probe 17 on operating head 13 just; as described probe 17 conductings of feeler and produce the signal of telecommunication; the signal of telecommunication reaches control system, and control system will be made shutdown immediately or other disposes instruction targetedly, disposes so that knitting needle 15 is ruptured or upwarps immediately; avoid affecting the fabric quality, avoid causing a chain of accident.
The above only is preferred embodiment of the present utility model, is not that technical scope of the present utility model is imposed any restrictions.The technical staff of the industry, under the inspiration of the technical program, can make some distortion and revise, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any modification, equivalent variations and modification that above embodiment does.
