Abstract
A doubling detection controller for weft yarns relates to a doubling mis-pick detection control device for weft yarns of a shuttleless loom. Doubling composite tension brackets are mounted on support feet; an annular organic glass baffle, tension discs and photoelectric detection heads are fixed on the doubling composite tension brackets; the photoelectric detection heads are directly mounted on a weft yarn rack after being fixed on the composite tension brackets; the controller is mounted in a switch control cabinet; and broken-pick stop signal wires led out of the controller are connected in parallel to a waste edge yarn or other process stop contact terminals through control wires. In case of breakage of a single weft yarn or paralleled yarns in the weaving process, the photoelectric detection heads generate photoelectric signals, the breakage signals are sent to the controller of the loom for processing and automatic stop is realized. The tension discs are fixed in the front of the photoelectric detection heads to ensure that yarns pass through a photoelectric sensor in a straightened state during unwinding. Therefore, mis-pick defective cloth caused by single breakage is avoided, the production of looped weft defects is reduced and the weaving quality and efficiency are improved.
Description
Technical field
The doubling of the utility model weft yarn detects controller, belongs to the textile machine equipment technical field, relates to a kind of shuttleless loom weft yarn doubling crapand detection control apparatus.
Background technology
The weft yarn crapand detector of shuttleless loom use both at home and abroad mainly contains mechanical arm and detects methods such as formula, piezoelectric ceramic type at present.Wherein mechanical arm detection formula is popped one's head in after certain hour is used for a long time in the workshop, and inside is long-pending easily spends, and the omission phenomenon takes place easily.Balanced yarn tension part is with the pressure of feeling to adjust a stage clip, makes the tension force between the yarn consistent as far as possible, causes the inconsistent phenomenon of artificial tension force easily.And piezoelectric ceramics micrometric displacement checkout gear cost is too high; And this device has requirement to the type that is connected again when being connected with the coupling of shuttleless loom; Can not be applied to the loom of other types, and checkout gear do not have the device of balanced yarn tension, this type of device is difficult to extensively popularize.
Summary of the invention
In order to overcome the deficiency of existing weft yarn crapand checkout gear; The utility model provides a kind of weft yarn doubling to detect controller; Crapand detection sensitivity, reliability, durability use compound tension bracket greatly to reduce the generation of looped weft at all not second to imported product.
The utility model solves the technical scheme that its technical problem adopted: select stand-off to install and the compound tension bracket of latitude; Also fixing circular lucite baffle plate, tension pulley, Photoelectric Detection head on the compound tension bracket of latitude; After being fixed on the Photoelectric Detection head on the compound tension bracket; Directly be installed on the weft yarn frame, controller is installed in the switch control cabinet.The staplings stop sign line of drawing in the controller is connected in parallel on slitter edge yarn or other technology parking contacts through control line.When single weft yarn or doubling broken end in weaving process, occurring; The Photoelectric Detection head can detect broken end timely and accurately and produce photosignal; Through the electric wire of drawing on the weft yarn doubling detection head; The signal that will break end is delivered in the loom controller and is handled, and is sent on the staplings stop sign outputs to slitter edge yarn or other parkings through one or two heart yearn the contact by controller then and carries out end break self-stop.Tension pulley is fixed on the front of Photoelectric Detection head, and yarn passes through photoelectric sensor with straight configuration when guaranteeing unwinding.
The beneficial effect of the utility model is; This device utilizes Photoelectric Detection, Digital Circuit Control system, improves the sensitivity that weft breakage detects greatly, stops the crapand defective cloth that single staplings causes; Even tension unanimity between each weft yarn when having guaranteed unwinding; Reduce the generation of the lax looped weft fault that causes of weft yarn, improved weave cotton cloth quality and efficient, reduced tender's labour intensity.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing is the system architecture diagram of the utility model.
1. baffle plate 2. and compound tension bracket 3. stand-offs of latitude 4. tension pulleies 5. Photoelectric Detection 6. controller among the figure
The specific embodiment
On the weft yarn frame of shuttleless loom before the weft accumulator according to former machine mounting means; Select stand-off 3 that two cover and the compound tension brackets 2 of latitude are installed; And the compound tension bracket 2 of latitude on fixing circular lucite baffle plate 1, two cover tension pulleies 4, two cover Photoelectric Detection 5; The bottom of the U type magnetic sheet on the Photoelectric Detection 5 is adjusted to than the high 1 millimeter position of tension pulley 4 centres joint, and controller 6 is installed in the switch control cabinet.Detection head a, b, c, d are connected to by behind controller 6 extended six heart yearns through three heart yearns, are connected to controller 6, and the staplings stop sign line of drawing in the controller 6 is connected in parallel on the contact of slitter edge yarn or other parkings through two heart yearns.Photoelectric Detection 5 can detect broken end timely and accurately and produce photosignal when single weft yarn or doubling broken end in weaving process, occurring; Through electric wire e, the f that draws on the weft yarn doubling detection head 5; The signal that will break end is delivered in the loom controller 6 and is handled; Send the staplings stop sign by controller 6 then, output to through one or two heart yearn on the contact of slitter edge yarn or other parkings and carry out end break self-stop.In addition, tension pulley 4 is fixed on the front of Photoelectric Detection 5, and through photoelectric sensor, and tension force keeps uniformity to yarn between each weft yarn, reduces the generation of the lax looped weft fault that causes of single weft yarn with straight configuration when having guaranteed unwinding.
Claims (3)
1. a weft yarn doubling detects controller; On stand-off, install and the compound tension bracket of latitude; Also fixing circular lucite baffle plate, tension pulley, Photoelectric Detection head on the compound tension bracket of latitude; Controller is installed in the switch control cabinet, it is characterized in that: after being fixed on the Photoelectric Detection head on the compound tension bracket, directly be installed on the weft yarn frame.
