Description
Technical field
The present invention relates to the comber of a kind of tricot machine with at least two group twizzles, the most often group twizzle is arranged on a driving element, and each 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
The comber of a kind of opposing force element having and driving element and be configured to air cylinder is also disclosed that in document DE10035160A1.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 DE10035160A1, 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 a common residual volume outside length of stroke, guides piston rod through described residual volume.
Described piston namely delivery in length of stroke in its cylinder the most respectively, thus the mobile route of piston does not the most change.Because cylinder expands to a residual volume outside length of stroke, so the change relatively caused by piston movement in the cylinder of overall volume is in the respective cylinders and notable the least than when only considering the volume of single cylinder in described residual volume.When piston moves in its 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 relative change in volume and the change of relative pressure are the least.In the comber with many group twizzles, described twizzle is arranged on respective driving element, and each drives element generally not to move all along equidirectional.Relatively, piston such as can arrange the pressure medium from its cylinder, meanwhile pressure medium can be made to enter into the inside of cylinder from residual volume by the motion of piston in another cylinder.
Preferably, described residual volume has cross section expansion section 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 oscillation and then cause the change 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.Described cylinder can not only be internal and can be externally mounted on described container.
It is preferred here that, 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 at external container without any problems.
Preferably, 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.Because the axis that the piston rod of each cylinder is parallel to respective cylinder extends, so the piston rod of multiple cylinder can be arranged by so-called fan in one plane, thus the most adjacent multiple driving element can connect by its corresponding opposing force element.
Preferably, described container bends on the opposed lateral surface of its lateral surface bent with described convex in concave shape.The lateral surface of this convex curve then forms a kind of so-called bowl, and the piston rod of each cylinder can converge in described bowl.When the curved surface of the lateral surface of described convex curve follows a circumference, then the dotted line extended through described piston rod just can intersect at the central point of circumference.
Preferably, at least big than the volume formed by the cross section of length of stroke and single 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 each 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 each passed through a sealing structure derives from described residual volume.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 respectively.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.
The invention still further relates to a kind of opposing force element for comber as above.This opposing force element namely have multiple piston cylinder structure, wherein cylinder expands to common 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.

Detailed description of the invention
Comber that schematically show in FIG, for tricot machine has many group twizzle 2a, 2b.First group of twizzle 2a is arranged on the first driving element 3a.Described first drives element 3a to be at one end connected with the first driving means 4a.Described first driving means 4a such as can be configured to pattern box (Mustergetriebe).Described first driving means also is able to have linear drive.
Described first drives element 3a to be connected with opposing force element 5 at the other end.Described opposing force element can describe in detail in conjunction with Fig. 2 to Fig. 4.
Second group of twizzle 2b and second drives element 3b to connect.Described second drives element 3b to be at one end connected with the second driving means 4b, and described second driving means can construct in the same manner as the first driving means 4a.Described second driving means also is able to otherwise construct.Described second driving means 3b is connected with opposing force element 5 at the other end.Described driving element 3a, 3b are configured to fine rule or cord in the present embodiment.They are not the most flexural rigidities and then can not bear pressure.
Described driving element 3a, 3b are connected with middleware 7a, 7b respectively, and each middleware in described middleware 7a, 7b is guided by slewing rollers 8a, 8b.
Described middleware 7a, 7b are connected with piston rod 6a, the 6b belonging to opposing force element 5 respectively.
Opposing force element 5 illustrates with only one piston rod 6 in fig. 2, in order to explain the principle of described opposing force element.But can also understand without any problems according to Fig. 4, when there is multiple piston rod 6, it is also possible to load this opposing force element for multiple driving element 3a, 3b.
Described opposing force element 5 has cylinder 9, and piston 10 can be arranged in described cylinder movably.Described piston 10 is connected with piston rod 6 mentioned above.Described piston rod 6 must be merely capable of transmitting pulling force, and can not transmit pressure.The most described piston rod 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.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 13.The most described cylinder 9 also be able to internally installed on the container, although embodiment shown in figure 2 is preferred.
When arranging multiple cylinder 9, these cylinders such as can be perpendicular to drawing surface and be sequentially arranged each other.
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 12.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 container 23 identical with the function of the container 13 in Fig. 2.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.
Described container 23 is provided with multiple cylinder 9.Each cylinder 9 has a piston rod 6, guides described piston rod through described container 23.Each piston rod 6 can be connected with driving element 3a, 3b.
The lateral surface 24 that described container 23 bends with having convex in the present embodiment.It also is able to use other make.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 element 3a, 3b, and described driving element 3a, 3b can connect again the most adjacent to each other.
Described cylinder 9 can be perpendicular to the drawing surface of Fig. 4 a and be sequentially arranged with plurality of rows of form, as shown in Fig. 4 b, 4c.When the bending section of the lateral surface 24 along convex curvature is disposed with eight cylinders 9 and is such as disposed with six this cylinders of row, just obtain 48 cylinders, these cylinders correspondingly can drive element 3a, 3b to be connected with 48 such that it is able to controls twizzle 2a, 2b of the group of respective numbers ....
Described container 23 has the lateral surface 25 of convex curve on the side opposed with the lateral surface 24 of convex curvature.Described container 23 namely generally form a kind of bowl.As can find out in fig .4, it is arranged so as to described piston rod 6, so that described piston rod points to common central point or points at least to common region.Realize in this region and drive element 3a, 3b ... or with middleware 7a, 7b ... connection.
Residual volume 12 it also is provided with, at least big than the volume formed by the cross section of length of stroke and single cylinder 9 100 times of described residual volume in described container 23.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.
