The specific embodiment
Shed forming device 1 shown in Figure 1 comprises four removable lifting- hooks 2,3,6 and 7 in top, they can by two be driven and anti-phase reciprocating griffe 10 with 11 vertical in couples move.More specifically, device 1 comprises two removable lifting-hooks 2 of carrying and 3 and two driven removable lifting- hooks 6 and 7, this carries removable lifting-hook and is connected by the hawser 4 of the funicular element that forms pile warp pulley 5, and this driven removable lifting-hook is connected by second hawser 8 that partly twines second pulley 9.Utilization belongs to carrying lifting- hook 2 and 3 hanger 2a and 3a, griffes 10 and 11 can optionally move described lifting- hook 2 and 3.
Driven lifting- hook 6 and 7 leans against respectively on the carrying lifting- hook 2 and 3 simply, this means that lifting- hook 2 and 6 can be griffed 10 to move together, just as lifting- hook 3 and 7 can be griffed 11 to move together.Like this, lifting- hook 2 and 6 is formed first pair of removable lifting-hook in top, and lifting- hook 3 and 7 is formed second pair of removable lifting-hook in top simultaneously.Needle selecting device 12 is set being used to that lifting- hook 2,3,6 or 7 is maintained static near the upper dead center position of track, rests at these lifting-hooks of this position and griffe on 10 and 11, described needle selecting device 12 for example comprise four unshowned by electronically controlled electromagnet.Single assembly 12 is used for selecting aforementioned four removable lifting-hooks, and this device 12 can be any suitable type.
Comparison diagram 1 to 6 can be clear that being positioned at the pulley 5 of device 1 central portion and the height of 9 frames with respect to weave mechanism (not shown) can change according to the relevant position of the removable lifting- hook 2,3,6 in top and 7.
Advantageously, these six pulleys 5,9,15,16,17 and 19 of device 1 are coplanes, and this can limit the lateral dimension of their formed assemblies, and simplify the structure of weave mechanism.
One guide rail 20 keeps four upper sheave 5,9,15 and 16 aligned with each other.Described guide rail 20 comprises elongate slots 20a, and sliding part 21 can move in this groove.Pulley 5 and 15 is installed on the sliding part 21, thereby described pulley can freely rotate, but fixes with respect to this sliding part aspect translational motion.In the pulley 9 and 16 one is installed in the upper end of guide rail 20 and another is installed in the lower end, thereby these pulleys can freely rotate, and fixing with respect to guide rail 20 aspect translational motion.Therefore, guide rail 20 is supported by upper sheave 9, and can move on short transverse with pulley 9.In addition, the 5th pulley 17 and the 6th pulley 19 are installed on second sliding part 18, so that these pulleys can freely rotate, but fix with respect to this second sliding part aspect translational motion.Sliding part 18 can be done translational motion with respect to the frame of weave mechanism, and by slideway (not shown) guiding translational motion.
One of them end of rope 23 is fixed on the base portion 22---this base portion 22 is fixed on the frame of weave mechanism---and pile warp pulley 16, pulley 17 and pulley 15 in succession, and hangs down into pulley 15 belows.The second end of rope 23 has the elastic hook 24 that is used to hang the heald (not shown), the position of this heald control warp thread.
The resilient force that the monofilament (not shown) is attached on the elastic hook 24 and opposing is applied by spring is to control the reciprocal vertical motion of corresponding heald, and this spring is connected to the lower end of heald on the frame of the loom that is equipped with this weave mechanism.As an alternative, a plurality of harness cords (harness cord) can be attached on the elastic hook 24, so that can utilize this elastic hook to control a plurality of healds.All harness cords that are attached on the different elastic hooks form this weave mechanism De Zong Fine-floss-silk (harness) together.
In addition, additional coupling arrangement comprises rope 25, and an end of this rope is fixed on second base portion 26 and pile warp the 6th pulley 19, and described second base portion is fixed on the frame of weave mechanism.Second end of the opposite side that is positioned at elastic hook 24 of rope 25 is equipped with the removable lifting-hook 27 in bottom.The removable lifting-hook 27 in bottom can be griffed 31 vertically to move by the bottom, and this bottom griffes 31 to be driven and to carry out and the motion of griffing 11 motion homophase, and its traverse H is with to griffe 10 and 11 traverse identical.
Operating process is as follows:
From configuration corresponding to Fig. 1 of the raised position of elastic hook 24, when griffe 10 be endowed vertically downward motion the time, if needle selecting device 12 keeps carrying lifting-hook 2 and driven hook perpendicular 6 simultaneously, then four upper sheave 5,9,15 and 16 all keep transfixion.Simultaneously, the removable lifting-hook 27 in bottom is accompanied by the bottom and griffes 31 to move vertically upward together.Because be attached to the tension force in the rope 23 that the heald of elastic hook 24 causes, pulley 17 trends towards rising towards lifting- hook 2,3,6 and 7.In the position shown in the figure 1, the tension force in the rope 25 and by being in the rising of configurations opposing pulleys 17 of griffing 31 regulations that dips.On the contrary, follow when rope 25 attached bottom lifting-hooks 27 thereon and to griffe 31 when rising together, rope 25 no longer hinders pulley 19, then this pulley 19 can rise towards raised position shown in Figure 2 by being promoted by pulley 17, since sliding part 18, the interval that pulley 19 is maintained fixed with respect to pulley 17.Then, the height of the 5th and the 6th pulley 17 and 19 rising H/2, this highly equals the bottom and griffes half of 31 traverse.Therefore, the length that rope 23 is wound on the part on pulley 16,17 and 15 in succession shortens, and this means that rope 23 crosses the length of the sagging part of pulley 15 greater than the length in the configuration shown in Figure 1.Therefore, thus the height that elastic hook 24 descends equals the traverse H that griffes of device 1 and obtains first centre position shown in Figure 2.
Once more from the configuration of Fig. 1, if driven lifting-hook 6 is remained on raised position by needle selecting device 12, and if carrying lifting-hook 2 be released so that it is followed griffes 10 to move downward, pulley 9 keeps its positions and pulley 5 descends to arrive position shown in Figure 4 so.With respect to therefore the descend height of H/2 of the pulley 15 of the fixed interval of pulley 5, this highly equals to griffe half of 10 traverse.Simultaneously, bottom lifting-hook 27 follows the bottom to griffe 31 to move vertically upward, make the 6th pulley 19 rise and arrive its raised position, this corresponding to the 5th pulley 17 by rising H/2 height.Therefore, the length that is wound on the part on pulley 16,17 and 15 in succession of rope 23 has reduced H+H=2H, promptly installs 1 the twice of griffing traverse H.So the height of elastic hook 24 decline 2H, thereby arrive second centre position shown in Figure 4.
From configuration shown in Figure 1, lifting-hook 2 does not limit driven lifting-hook 6 yet if needle selecting device 12 neither limits carrying, and then pulley 5 and 9 is all with downward translation H/2 height.Therefore, pulley 16 decline H/2 height and the pulley 15 with respect to pulley 9 fixed-site also reduces the H/2 height.Simultaneously, 31 rising is griffed in the bottom that bottom lifting-hook 27 is followed makes the 6th pulley 19 can move to raised position, simultaneously with respect to the 5th pulley 17 rising H/2 height of pulley 19 fixed-site.This causes the length that is wound on the part on pulley 16,17 and 15 in succession of rope 23 to reduce H+H+H=3H, promptly install 1 griffe three times of traverse H.Therefore elastic hook 24 decline 3H height is to arrive down position shown in Figure 6.
Therefore, can be that elastic hook 24 obtains four equally spaced positions according to each device 1 of the weave mechanism of present embodiment, the spacing between two adjacent positions equals the traverse H that griffes of device 1.As mentioned above, two centre positions can be used for odd number and throw a spear.But the even number that these two centre positions also can be used for shown in the configuration of Fig. 3 and 5 is throwed a spear, and the similar principles illustrated that is used for Fig. 2 and 4 can be applicable to the motion of the pulley of Fig. 3 and 5.The raised position of elastic hook 24 only is used for even number throws a spear, and throws a spear and down position only is used for odd number.
In the weave mechanism of described embodiment, advantageously, shed forming device 1 is grouped into eight and installs one group to form the module that can be assemblied in separately in the weave mechanism.As an alternative, the device number in the module can be different from eight.
In addition, because device 1 according to the present invention can obtain four positions, wherein two is not only to be used for even number to throw a spear but also be used for the centre position that odd number is throwed a spear, so this device 1 can be used for carpet weaving, and be used to activate the device of upper strata suede yarn and be used to activate any difference that does not exist between the device of lower floor's suede yarn on the structure or on the control mode.In addition, according to weave mechanism of the present invention all the device 1 all directly by griffe 10,11 and 31 control.---this can make pulley 15,16 and 17 moves needs four position consistency arriving with elastic hook 24 traverse---provided by the element of device 1 inside and all identical for all devices of weave mechanism to griffe the reducing of motion amplitude, so advantageously simplified the structure that the loom of this weave mechanism for example is housed and reduced the occupation of land size.
Utilize device 1 of the present invention, three pulleys 15,16 and 17 of being responsible for elastic hook 24 motions can move independently of each other, and even number is throwed a spear and odd number is throwed a spear to be used for.By setting motion with H/2 traverse for pulley 17, make described four positions of elastic hook 24 equidistant, therefore optimized the load on shed open opening and the loom.In addition, the vertical alignment of the composed component of device 1 has limited shared space.Therefore the loom that is equipped with weave mechanism of the present invention is very compact.
The present invention be not limited to described and shown in example.Particularly, according to first alternative of the present invention (not shown), griffe 11 and 31 can be griffed 11 two parts and replaced by single, this griffes 11 be dimensioned to and can arrive top lifting- hook 3 and 7 and bottom lifting-hook 27.Use this length griffe 11 can griffe actuating device and save the space by omitting one.In addition, although there is additional bottom lifting-hook 27 this moment, installs 1 machinery control and control identical with the machinery that comprises two can be anti-phase mobile conventional apparatus of griffing.Also can consider to install some device 1 according to loom of the present invention by griffing to activate about identical, its middle and lower part lifting-hook 27 is positioned at homonymy with the left hand top lifting-hook of device 1, and its middle and lower part lifting-hook 27 and the right hand top lifting-hook of device 1 be positioned at other device 1 of homonymy, then by around the alignment axis Rotate 180 of pulley ° with inversion set 1.So this produces the system of a complete equipilibrium, wherein griffe 10 and 11 all to be designed to arrive top lifting-hook and bottom lifting-hook for two kinds, and every kind of half of griffing only to carry in the lifting-hook of bottom.In addition, the return force that Zhi Ji Zong Fine-floss-silk applies trends towards upwards spurring pulley 17 and 19, this means at the whole motion process middle and lower part lifting-hook 27 of griffing and griffes to remain between 11 contact.Bottom lifting-hook 27 is applied to griffes power and the top lifting- hook 3 and 7 of 11 downsides and is applied to that to griffe the power of 11 upsides opposite, this means that additional lifting-hook 27 can 11 further not apply bending stress to griffing.
According to second alternative of the present invention (also not illustrating), bottom lifting-hook 27 can be associated with the electronic needle selecting device that is similar to the needle selecting device 12 that is used for the top lifting-hook.Then only when Electronic Control has ended that bottom lifting-hook 27 remained on its down position, this bottom lifting-hook 27 just follows the bottom to griffe 31 motions.Like this, can with pulley 19 and and then pulley 17 remain on and be used for the down position that odd number is throwed a spear.Therefore installing 1 can have three additional configuration, this means that raised position and two centre positions both can be used for even number and throwed a spear and also can be used for odd number and throw a spear, and down position keeps only being used for odd number and throws a spear.As a result,, can when throwing a spear continuously for twice, keep raised position and two centre positions, therefore limit the part count that must move for the invariant position that keeps elastic hook 24 by when throwing a spear next time, adopting symmetrical needle selection to the top lifting-hook.
