Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail:
Schematic diagram shown in the accompanying drawing 1 for the preferred embodiment of the weft selector of air-jet loom of the present invention, there is shown eight weft-accumulators 1, two groups are changed latitude unit 8, one has the main burner 2 of two nozzles 21, wherein each group is changed latitude unit 8 and is comprised that four are received latitude devices 3, one has the weft-selecting mechanism 4 of four weft-selecting mechanism nozzles 41, per four weft-accumulators 1 and one group of nozzle that changes latitude unit 8 and main burner 2 form a weft yarn passage, so in this specific embodiment, two weft yarn passages are arranged, be passage A and channel B, each passage can hold the selection of four kinds of weft yarns, so two passages can hold the selection of eight kinds of weft yarns altogether, it is not limitation of the present invention that but the quantity of above-mentioned passage and each passage can hold the quantity of weft yarn, the every passage of the present invention can hold more than tens kinds of weft yarns, only provide the situation of four kinds of weft yarns of every passage at this, at first introduce existing loom weft selector structure below:
As Fig. 8, can carry out maximum four kinds of weft yarns shown in the figure and select situation, comprise that main burner 2 with four nozzles, four are respectively applied for the weft-accumulator 1 that discharges weft yarn, four auxiliary main burners 9, main burner 2 is installed on the slay of air-jet loom, this slay is made high-speed motion when air-jet loom is weaved work, and each nozzle of main burner 2 distributes and is provided with the airflow control mechanism (not shown), this airflow control mechanism is optional to be realized with electromagnetic valve, this is a common practise in the present technique field, does not repeat them here.In the time of work, the weft yarn that each weft-accumulator 1 discharges is directed into main burner 2 through auxiliary main burner 9, thereby realizes that by controlling different airflow control mechanisms different weft yarns carries out wefting insertion, has also promptly realized selecting the function of latitude.
To introduce the structure and the function of the technical characterictic of the present invention and prior art difference below in detail:
Contrast Fig. 1 and Fig. 8 are as can be seen, between weft-accumulator 1 and main burner 2, be provided with among Fig. 1 and change latitude unit 8, it is its position that has replaced auxiliary main burner 9, the another one difference is, main burner 2 among Fig. 8 has four nozzles realizations and selects latitude for four kinds, and the main burner 2 among Fig. 1 only has two nozzles, by a plurality of latitude unit 8 that change, only have the main burner 2 of two nozzles just can realize surpassing the latitude that selects of four kinds of weft yarns, below emphasis every group of functional part that changes in the latitude unit 8 introduced one by one:
Every group is changed and comprises two kinds of functional parts in the latitude unit 8, promptly receives latitude device 3 and weft-selecting mechanism 4, at first introduces and receives latitude device 3.
Described each receipts latitude device 3 has the receipts state and puts two duties of state, and when described receipts latitude device 3 was in the receipts state, the weft yarn that passes from weft-accumulator 1 was subjected to described receipts latitude device 3 constraints to be in the state of harvesting and storing; When described receipts latitude device 3 is in when putting state, the constraint that the weft yarn that passes from weft-accumulator 1 breaks away from described receipts latitude device 3 is in free extended configuration.In the present embodiment, receive stationary part 32 and stationary part 33 that latitude device 3 comprises a motion portion 31, described motion portion 31 both sides are set, when described motion portion 31 laid respectively at stationary part 32, stationary part 33 tops, described receipts latitude device 3 was in the state of putting, as shown in Figure 2; When described motion portion 31 was positioned at stationary part 32,33 belows, described receipts latitude device 3 was in the receipts state, as shown in Figure 3.Motion portion 31, stationary part 32 and stationary part 33 can adopt roller, and a plurality of rollers are formed the roller group, as shown in Figure 2, be in when putting state when receiving latitude device 3, moving roller is above quiet roller, and weft yarn passes in the middle of quiet roller and moving roller, and the roller group is to not constraint of weft yarn.As shown in Figure 3, when receiving latitude device 3 and be in the receipts state, moving roller has moved to the below of quiet roller, and be with weft yarn wear around, its weft yarn wear around length should with the equal in length that weft yarn is extracted out from main burner.
The major function of receiving latitude device 3 is to form the receipts state and put two duties of state, the above-mentioned specific embodiment receiving latitude device 3 that only provides, but the design of receiving latitude device 3 is not subjected to this structural limitations, can increase as the roller number in the roller group, has so just increased weft yarn and has worn around number of times; Perhaps without roller, utilize the across displacement of two smooth pectination objects also can realize weft yarn wear around.
When moving roller moved down, the weft yarn left side was retrained by weft-accumulator, and weft yarn the right is a free end, can extract weft yarn out from main burner, and This move is called back yarn at this.Otherwise when moving on the moving roller, weft yarn is moved right by the traction of weft-selecting mechanism nozzle 41 air-flows, and passes main burner, receives latitude device 3 simultaneously and is in the state of putting, and This move is called into yarn at this.If passage has only the main burner of a nozzle, such main burner can only hold a weft yarn, so when changing latitude, want earlier back yarn, extracts the original weft yarn in the main burner out, advances yarn then, and the yarn that is advanced is the new weft yarn of selecting in this passage just.Finishing and change the required back yarn of latitude, advance yarn action can not finish in moment, so the present invention is provided with two passages, and when passage A carried out wefting insertion, channel B can be changed the latitude operation, make thus wefting insertion and change latitude can continuous carrying out.
Plural passage can certainly be set, for example four-way can be set, the main burner that has four nozzles now is very common on market, can win more time for changing latitude like this; Can also mix on the basis of four spray main burners and cooperate: promptly wherein two nozzles are in order to be configured to passage A and the channel B that multiple weft yarn is selected, and two other nozzle is directly introduced weft yarn.On the basis of technical scheme of the present invention, the technical staff can design more complicated multichannel device or multiple weft yarn and single device of planting the weft yarn mixed configuration, is not the technological break-through to essence of the present invention.
In the present embodiment, receive latitude device 3 and go back the double as weft brake.Moving roller motion makes weft yarn contact with roller, has increased the resistance when weft yarn flies, the effect of Here it is weft brake.In the process of wefting insertion, weft yarn high-speed flight under the effect of air-flow can be subjected to suddenly ending the constraint of yarn pin and weft yarn being tightened at the latter end that flies, and this unexpected tightening is easy to make breakage of weft.The method that solves is that the latter end in weft yarn flight artificially increases some dampings, and weft yarn is slowed down, the effect of Here it is weft brake, and weft brake also claims WBS.As can be seen, the roller group can increase the resistance of weft yarn flight with when weft yarn has a little to contact, and plays the effect of weft brake.Because the displacement of moving roller is that electricity is controlled, so the size of weft yarn braking damping also is adjustable.
Introduce weft-selecting mechanism 4 below again:
Each described weft-selecting mechanism 4 comprises pedestal 42, is fixedly installed on a plurality of weft-selecting mechanism nozzles 41 on the pedestal 42, clearly, the quantity of open ended weft-selecting mechanism nozzle 41 is identical with the open ended general election latitude species number of the passage at these weft-selecting mechanism 4 places on the pedestal 42 of each weft-selecting mechanism 4, and the receipts latitude device 3 and the weft-accumulator 1 of its configuration also should be identical quantity.
In order to make each nozzle in a plurality of weft-selecting mechanism nozzles 41 can move to the most suitable position of advancing yarn and wefting insertion selectively, weft-selecting mechanism 4 of the present invention also is provided with and makes described pedestal 42 produce the displacement mechanism (not shown) of displacement, this displacement mechanism can utilize existing electric machines control technology or magnet control technology to realize, this is the habitual mechanism in this area, no longer use description of drawings at this, thereby make each weft-selecting mechanism nozzle 41 can produce certain displacement by this displacement mechanism.
