Stress variation in the driving element is desired to be small. For the purpose, the cylinder (9) extends beyond the stroke length to form a residual volume (12) to guide the piston rod (6) to pass through the residual volume.
Description
Technical field
The present invention relates to the comber of a kind of tricot machine with at least one twizzle, described twizzle is arranged on a driving element, described driving element is effectively connected with driving means and with at least one opposing force element, wherein said opposing force element has piston cylinder structure, in described piston cylinder structure, the piston being connected with described driving element by piston rod can be moved with certain stroke length in the cylinder and can be loaded by pressure medium.
Background technology
Such as also disclosed that such a comber by document DE 100 35 160 A1.Driving means makes described driving element and then the twizzle being connected with described driving element is moved such that it is able to will be programmed into according in the fabric (Wirkware) of a certain predetermined pattern by the silk thread of twizzle delivery.When described driving element constructs the most rigidly, such as in the case of so-called " string comb (String-Barre) ", driving means and opposing force element work together to drive on element, in order to make described driving element keep tensioning.
This is existed following risk, the i.e. pulling force for tensioning and can cause the length elongation of described driving element.This length elongation can damage positioning precision.This may result in twizzle and collides with other effective tools.Although this length elongation can be considered with calculated in advance and when design, there is problems in that, by in comber disclosed in document DE 100 35 160 A1, pulling force is the most non-constant, because pressure medium there occurs that pressure changes when piston moves in the cylinder, the change of described pressure result in again power transmission change.
Summary of the invention
The task of the present invention is, makes the stress elongation in driving element keep less.
This task is solved in the following manner by the comber being initially mentioned, i.e. cylinder expands to residual volume outside length of stroke, guides piston rod through described residual volume.
Described piston namely delivery in length of stroke in its cylinder as previously mentioned, thus the mobile route of piston does not the most change.Because cylinder expands to residual volume outside length of stroke, thus cylinder and the overall volume of residual volume, the relative change that caused by piston movement in the cylinder less than when only considering the volume of cylinder.When described piston moves in the cylinder, the volume arranging pressure medium is drawn by the product of length of stroke with the cross section of cylinder.Then relative to the business of the volume that arranged by this of change and overall volume draw.Described overall volume is the biggest, and the change of relative pressure is the least.
Preferably, described residual volume has enlarged-diameter portion relative to cylinder.Described cylinder namely be directly transitioned in residual volume.Will not be produced the flow resistance of interference by the movement of piston when shift pressure medium, described flow resistance can cause again pressure to raise and then cause the rising being applied to drive the pulling force on element.
Preferably, described residual volume constructs in a reservoir, and described cylinder is installed on the container.This simplify manufacture.Only in the size that can determine described cylinder with piston in the case of coefficient.Otherwise, design based on described residual volume just can determine the size of described container.Then pass through assembling cylinder and container has obtained desired combination.
To this preferably, described cylinder is externally mounted on described container.Thus the overall volume within container uses as residual volume.Cylinder control and the movement of piston if desired can be carried out without any problems outside cylinder.
Preferably, at least big than the volume formed by the cross section of length of stroke and described cylinder 100 times of described residual volume.Thus relative to change in volume remain less than 1%.Thus the change by the pressure caused by change in volume is the least.And drive the stress changes on element to be at a kind of insignificant magnitude, thus it is not result in that the length of described driving element changes.
Preferably, between described cylinder and described residual volume, only one cross section transition part it is provided with.The most possible flow resistance is reduced to minima, and the transfer of the pressure medium caused by the movement of piston is not result in less desirable pressure oscillation.
Preferably, described piston rod is derived from described residual volume through a sealing structure.Described residual volume is positioned at the side of piston, and described piston rod also is disposed on this side.Described sealing structure ensure that, the loss of the pressure medium that is in operation can be kept as less, thus must refill the most less pressure medium.
Preferably, described piston rod is connected with described driving element by a turning part.Thus unrestricted choice has the position that the piston cylinder structure of residual volume can be disposed thereon.Enable in particular to apply multiple driving element that can be disposed adjacently to one another, without colliding with corresponding opposing force element.
Preferably, described residual volume is connected with at least two cylinder.Said two cylinder is such as associated with the different opposing force element driving element.Because the most described driving element can not accurately synchronizing moving, it is possible to use the residual volume for multiple cylinders, without causing less desirable pressure oscillation simultaneously.
It is preferred here that, described residual volume constructs in the container of the lateral surface bent with having convex, is disposed with described cylinder on described lateral surface.The lateral surface of described convex allows described cylinder to point to different directions.Extending because the piston rod of each cylinder is parallel to cylinder-bore axis, so the piston rod of multiple cylinder can be arranged by so-called fan in one plane, thus multiple driving element being closely disposed adjacent to can connect by its corresponding opposing force element.
The invention still further relates to a kind of opposing force element for comber as above.This opposing force element namely have a piston cylinder structure, wherein cylinder expands to residual volume outside length of stroke, guides piston rod through described residual volume.For this opposing force element, obtain the least pressure change due to bigger residual volume when piston moves in the cylinder.

Fig. 1 is the extremely schematically diagram of comber；
Fig. 2 is the profile of opposing force element；
Fig. 3 is the enlarged drawing of the intercepting section III shown in Fig. 2；And

Detailed description of the invention
Comber that schematically show in FIG, for tricot machine has multiple twizzle 2.Described twizzle is arranged on driving element 3.Described driving element 3 is configured to fine rule or cord in the present embodiment.Described driving element 3 is not the most flexural rigidity and then can not bear pressure.
Described driving element 3 is at one end connected with driving means 4.Described driving means 4 such as can be configured to pattern box (Mustergetriebe).Described driving means also is able to have linear drive.
Described driving element 3 is connected with opposing force element 5 at the other end.Described opposing force element 5 can be described in detail in conjunction with Fig. 2.Described opposing force element 5 has piston rod 6, and described piston rod is connected with described driving element 3 by middleware 7.Described middleware 7 is guided by slewing rollers 8.
Described opposing force element 5 has cylinder 9, and piston 10 is movably disposed within described cylinder.Described piston 10 is connected with above-mentioned piston rod 6.Described piston rod 6 must be merely capable of transmitting pulling force, and can not transmit pressure.The most described piston rod 6 also bends and constructs flexibly, namely is such as configured to relatively thin line.
Described cylinder 9 such as can be configured to glass cylinder such that it is able to from the movement of outside monitoring piston 10.
Described cylinder 9 has internal volume 11, and described internal volume is transitioned into residual volume 12 with unique cross section change.Described residual volume 12 is arranged in container 13.Described container 13 has swagelok 14, and receiving portion 15 is placed in described swagelok 14.Described cylinder 9 is placed in described accommodation section 15.As can be seen from Figure 3, the inwall 16 of described cylinder 9 has the diameter identical with the inwall 17 of described accommodation section 15.Described accommodation section 15 utilizes the medial surface 18 of container to close.
Described cylinder 9 expands to residual volume 12 outside length of stroke, and described piston 10 can move in the cylinder in described length of stroke, and described residual volume essentially show relative to described cylinder 9 cross section expansion section.Described cylinder 9 is unlimited on the side deviating from described residual volume 12.It communicates with air there.
Shown in figure, described cylinder 9 is externally mounted on described container.The most described cylinder 9 also be able to internally installed on the container, although embodiment shown in figure 2 is preferred.
Described container 13 such as can surround residual volume 12.About the biggest than the volume that the product of the interior cross section by length of stroke and cylinder 9 is formed 2950 times of this residual volume.Fig. 2 can not show this point in this respect from ratio.
Described container 13 has compressed air joint 19, supplies the air of certain pressure to constantly by described compressed air joint described container 13.Therefore described air defines pressure medium.
When the piston 10 in described cylinder 9 moves in its whole length of stroke, such as with certain orientation towards container 13, then the certain volume from cylinder 9 is squeezed in residual volume 12 by it, and described certain volume is fairly small compared with the volume of residual volume 12.Relatively, the raising of the pressure of the pressure medium during this exclusion does not actually interfere with described container 13.It is applied to power on piston rod 6, that relatively imported in driving element 3 by intermediary element 17 and the most relatively keeps constant.Thus reliably avoid pressure oscillation and then avoid power transmission fluctuation.
Described piston rod 6 is derived from described container 13 through sealing structure 20 on the side opposed with described cylinder 9 of described container 13.Relatively, this position make pressure medium loss less or the most virtually completely avoid pressure medium loss.
The most as can be seen from fig. 3, described accommodation section 15 has opening 21, can be disposed with pressure transducer in said opening.When need not pressure transducer, it is also possible to close described opening 21.
Because being alternately provided with only only one cross section transition part between described cylinder 9 and described residual volume 12, so also will not produce additional flow resistance, described flow resistance can cause again the pressure oscillation in cylinder 9.Therefore the pressure medium from described cylinder 9 squeezed in described residual volume 12 or squeeze in cylinder 9 and can carry out under being difficult to the pressure oscillation discovered in turn by the pressure medium from residual volume 12.
Fig. 4 shows the design of the modification of container 23, is wherein provided with multiple cylinder 9 on described container 23.Each cylinder 9 has a piston rod 6, guides described piston rod through described container 23.
Here, Fig. 4 a shows that the side view of container 23, Fig. 4 b show that the top view of container 23 and Fig. 4 c show the front view of container 23.Described container 23 also has compressed air joint 19 at this.As can be seen that the most in fig .4, described container 23 is at the lateral surface 24 bent with having convex.The lateral surface 24 that described cylinder 9 bends with being approximately perpendicular to this convex is arranged, thus described piston rod 6 can be arranged the most generally fan-shapedly.Relatively, the piston rod 6 of different cylinders 9 drives element can be connected by from different driving elements 3, and described driving element can connect again the most adjacent to each other.The opposing force element 4 ' that figure 4 illustrates can be utilized to connect such as 48 and to drive element 3, thus the twizzle of the group of respective numbers can move controllably.
This design also specifies, container 23 is provided with residual volume 12, at least big than the volume formed by the cross section of length of stroke and each cylinder 9 100 times of described residual volume.Therefore therefore deduce that, and not all piston in same direction and moves with identical amount simultaneously.Relatively, described container 23 can accommodate pressure medium simultaneously, and described pressure medium is discharged from cylinder again, and pressure medium is sent in other cylinders 9.This also makes the pressure oscillation in pressure medium and then the fluctuation of the power transmission on piston rod 6 less.
