Abstract
The utility model provides a self-adaptive weft-catching device, which comprises an infrared positioning frame arranged on a weft-catching end opposite to the nozzle of a loom, a loom weft-catching member and a control module. The infrared positioning frame is arranged in front of the loom weft-catching member. An infrared emitting head and an infrared receiving head are arranged in the infrared positioning frame, wherein infrared signals are transmitted between the infrared emitting head and the infrared receiving head. The loom weft-catching member is arranged on a two-dimensional moving member. The control module and the infrared positioning frame are electrically connected with the two-dimensional moving member. According to the technical scheme of the utility model, the position data of a weft yarn is acquired by the infrared positioning frame and then is transmitted to the two-dimensional moving member by the control module. After that, the loom weft-catching member is moved to the position of the weft yarn by the two-dimensional moving member, so that the weft yarn can be accurately caught by the loom weft-catching member.
Description
Affiliated technical field
The utility model relates to shuttleless loom field, especially, is that a kind of self adaptation of shuttleless loom is caught Weft handling device.
Background technology
The common basic characteristics of shuttleless loom are that weft yarn package is separated from shuttle, or only carrying a small amount of weft yarn replaces massive shuttle with small and light weft insertion device, for high speed wefting insertion provides favourable condition.In the supply of weft yarn, directly adopt again bobbin package, enter weft insertion device by storage Weft handling device, make loom break away from weft replenishment action frequently.Therefore, adopt shuttleless loom for increase fabric variety, adjust fabric construction, reduce fabric defects, improve fabric quality, reduce noise, improve working conditions significant.The shuttleless loom speed of a motor vehicle is high, conventionally than the high 4-8 of fly-shuttle loom efficiency doubly, applies shuttleless loom so large-area, can increase substantially labor productivity.
Shuttleless loom is owing to not having shuttle guiding weft yarn to fly in shed open, and the weight of weft yarn self is very light, therefore weft yarn is easily subject to the interference of air drag, impurity or gravity in transmitting procedure, weft yarn enters while catching Weft handling device it to be incorporated in advance latitude coordinate more inaccurate passing through very long shed open, once exceed the range of allowable error of catching Weft handling device, easily cause the accident of sluff-offs.
Utility model content
In order to address the above problem, the purpose of this utility model is to provide a kind of self adaptation to catch Weft handling device, and this self adaptation is caught Weft handling device and can locate the wefting insertion terminal of weft yarn.
The utility model solves the technical scheme that its technical problem adopts:
This self adaptation is caught Weft handling device and is comprised that being arranged on loom spout opposite catches infrared posting, the loom of latitude end and catch latitude member and control module, described infrared posting is arranged on loom catches the front of latitude member, in described infrared posting, be provided with infrared emission head and the infrared receiving terminal of correlation, described loom is caught latitude member and is arranged on two-dimensional movement member, described control module and described infrared posting and the electrical connection of described two-dimensional movement member.
As preferably, described infrared posting adopts infrared touch frame to make.
As preferably, four angles of described infrared posting are fixedly connected with respectively three elastic webbings and a connecting rod, and wherein the other end of three elastic webbings is connected to and is fixedly connected with chain, and the other end of described connecting rod connects the Eccentric-hinge contact of a rotating disk.
As preferably, the Eccentric-hinge contact of described rotating disk is apart from the distance in the center of circle, is less than loom and catches the half of latitude member admissible error radius.
The utility model has the advantage of:
The position data of the weft yarn that described control module obtains described infrared posting is transferred to described two-dimensional movement member, and described two-dimensional movement member is caught by described loom the position that latitude member moves to weft yarn and caught accurately latitude.
Brief description of the drawings
Fig. 1 is the structural representation that this self adaptation is caught Weft handling device.
Fig. 2 is the structural representation that this self adaptation is caught the infrared posting of Weft handling device.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
In the present embodiment, consult Fig. 1 and Fig. 2, this self adaptation is caught Weft handling device and is comprised that being arranged on loom spout 100 opposites catches infrared posting 300, the loom of latitude end and catch latitude member 200 and control module, described infrared posting 300 is arranged on loom catches the front of latitude member 200, in described infrared posting 300, be provided with infrared emission head and the infrared receiving terminal of correlation, described loom is caught latitude member 200 and is arranged on two-dimensional movement member 210, and described control module and described infrared posting 300 and described two-dimensional movement member 210 are electrically connected.
The position data of the weft yarn 10 that described control module obtains described infrared posting 300 is transferred to described two-dimensional movement member 210, and described two-dimensional movement member 210 is caught by described loom the position that latitude member 200 moves to weft yarn 10 and caught accurately latitude.
Above-mentioned self adaptation is caught Weft handling device, and described infrared posting 300 adopts infrared touch frame to make, and adopts the device of common on the market infrared touch frame as location weft yarn 10, with low cost and reliable operation.
Above-mentioned self adaptation is caught Weft handling device, four angles of described infrared posting 300 are fixedly connected with respectively three elastic webbings 310 and a connecting rod 320, wherein the other end of three elastic webbings 310 is connected to and is fixedly connected with chain, and the other end of described connecting rod 320 connects the Eccentric-hinge contact 410 of a rotating disk 400.
Due to the rotation of rotating disk 400, drive described infrared posting 300 that annular skew occurs, because the monitoring light of the infrared emission head in infrared posting 300 and infrared receiving terminal correlation composition not covers completely to whole plane, once weft yarn 10 passes between two monitoring light, will monitor error, and the described infrared posting 300 of annular offset can make to monitor light generation displacement, this displacement can be monitored the plane that covers whole infrared posting 300.
Above-mentioned self adaptation is caught Weft handling device, and the Eccentric-hinge contact 410 of described rotating disk 400 is apart from the distance in the center of circle, is less than loom and catches the half of latitude member 200 admissible error radiuses, reduces the scope of skew, ensures that weft yarn 10 can monitor more accurately.
Above-mentioned self adaptation is caught the principle of wire drawing of Weft handling device:
On described infrared posting 300, the monitoring light of infrared emission head and infrared receiving terminal composition obtains the position data after weft yarn 10 passes, the position data of the weft yarn 10 that described control module obtains described infrared posting 300 is transferred to described two-dimensional movement member 210, and described two-dimensional movement member 210 is caught by described loom the position that latitude member 200 moves to weft yarn 10 and caught accurately latitude.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., all should be included in protection domain of the present utility model.
