Description
Technical field
The present invention relates to a kind of feed carrier of warp knitting machine, it has at least one guide unit and at least one driving element, wherein the guide unit has the thread-carrier with the handle bar, and this handle bar is connected with holding element, and this holding element is arranged on driving element and has clamping area.
Background technology
Warp knitting machine for generation of the braided fabric with complex pattern has various so-called " String-Barren (tandem sley bar) ".In this tandem sley bar, the thread-carrier usually consisted of sley point is separately fixed on a driving element in groups.When driving element moves, make corresponding thread-carrier move together.Organize thread-carriers at these a plurality of driving elements with correspondingly more and can be arranged on common sley bar body, it can additionally move.Thread-carrier spacing in one group is corresponding to for example textile design circulation.
In the time that pattern will be changed, must change the thread-carrier position.Must pull down the guide unit from driving element for this reason, make the guide unit motion to another location and make again it be fixed on driving element there.
Feed carrier by the known a kind of above-mentioned form of DE 101 37 601 A1.Holding element has one-sided unlimited groove there, by it, holding element is placed on driving element.Then make holding element by means of fixed substance, for example bonding agent fixed bonding on driving element.Make adhesive hardens.If other position on driving element needs the guide unit, remove the guide unit and use new guide unit, be fixed on driving element for making it.There is another kind of alternative, the guide unit is clamped on driving element by pinching screw.
DE 100 38 264 C1 have described a kind of for making thread-carrier be fixed on the device on sley bar, wherein make screw be arranged in the extension body of handle bar.The handle bar has the clamping area of inclination.The holding element of the clamping area with reversed dip is set on screw head.Two clamping areas are clamped in therebetween sley bar.
Although two kinds of solutions are in practice through test.But for being fixed on driving element, the guide unit all needs to use special holding element, for example screw or bonding agent in both cases.Both make the change in location of guide unit on driving element relatively bothersome.
Summary of the invention
The objective of the invention is, in simple mode, change the position of guide unit on driving element.
This purpose is achieved thus in the feed carrier of above-mentioned form, be that described handle bar can be rotatably set in holding element and in clamping position and has at least two different diameters, the distance wherein clamped between position and clamping area is greater than the thickness of driving element in the first position of rotation, and is less than the thickness of driving element in the second position of rotation.
By this modification structures, the guide unit can be fixed on driving element, without additional element.For fixing, between guide unit and driving element, use frictional engagement to be connected.When the guide cell moving locational the time, only needs the handle bar of thread-carrier around its axis rotation to desired.In the first position of rotation of handle bar, the distance that makes to clamp between position and clamping area is large like this, and the guide unit can be shifted with respect to driving element.The larger diameter that clamps position at the second position of rotation acts on driving element, and makes the driving element top press clamping area.Make thus the guide unit be fixed on driving element with enough degree.This brings obvious jump while reorientating in the guide unit.Needn't handle again outer member.Usually also without for making the guide unit be fixed on the instrument on driving element.
Described handle bar preferably has the diameter increased continuously in clamping position.Consequently, the distance that makes to clamp between position and clamping area little by little diminishes, and can apply very subtly clamping force thus.The periphery that clamps position extends a circle according to the form of spiral here.Realize thus the difference of the maximum possible between the first diameter and Second bobbin diameter.Can work as thread-carrier while thering is predetermined orientation at this, make aptly maximum gauge act on driving element.Whether this is easy to monitor simultaneously, clamp and realize or do not realize in desired mode.
Described holding element preferably has handle bar section and surrounds the maintenance section of driving element, inserts the handle bar in this handle bar section.Make thus holding element be connected with driving element and with the handle bar reliably.The clamping of holding element on driving element can not have hidden danger ground to realize, that is, driving element can not eject from holding element or the handle bar can not break away from holding element.
If described handle bar section is configured to tube element, especially can realize such scheme.Tube element, the structure that especially has a circular cross section have following advantage, i.e. independently always accurately guiding of handle bar and its position of rotation, and be applied to the position on driving element with desired clamping force simultaneously.
Also advantageously, described maintenance section is configured to tubulose.In this case, described guide unit can not be bearing on driving element with breaking away from.This driving element can have circular cross section.It for example can consist of wire or rope, wherein must make rope form so rigidly, makes it also can transmission of pressure.If driving element has circular cross section, keep section preferably to there is equally circular cross section.If the cross section of driving element is not circular, advantageously, the cross section of described maintenance section is matched with this shape.
In selectable modification structures, described purpose is achieved thus, and described holding element has corresponding clamping area, and described clamping area and corresponding clamping surface elastic ground is pretension in opposite directions, and makes the holding element mounting board on driving element.In this modification structures, also can make the guide unit not be fixed on driving element with thering is no add ons.Only need certain pressure on holding element, slightly expand for making clamping area and corresponding clamping area overcome its elastic force, and make the holding element mounting board on driving element.Consequent clamping force is enough to make the guide unit to be fixed in position reliably under normal condition.Change the position of guide unit on driving element if essential, can simply the guide unit be pulled down from driving element, for example, perpendicular to vertical extension of driving element.Then can make the guide unit be displaced to another location on driving element and mounting board there again.
Preferred at this, make described holding element there is U-shaped cross-section, it has two sides and a base limit, wherein said side opposite tilt when there is no driving element, and maximum until parallel-oriented by the driving element expansion be arranged on therebetween.The advantage of this modification structures is, described driving element can be because clamping area and corresponding clamping area are not applied to pressure on driving element together eject from the intermediate space between clamping area and corresponding clamping area.But remain between clamping area and corresponding clamping area with making the driving element reliable grip.
Also advantageously, described handle bar is fixed on Ji Bianshang, wherein makes driving element be arranged in the groove of sley bar, and the base limit is arranged on deviate from a side of bottom land.Can make in this way fixed position easily from the open side mounting board of groove on driving element.Therefore without the sley bar unit of dismantling driving element fully and setting within it.
In two kinds of alternatives, advantageously, in the holding element both sides, guide element is fixed on driving element.If driving element is arranged in the groove of sley bar body, guide element is responsible for making holding element not contact with the sley bar body.Making holding element be fixed on clamping force on driving element also only need bear yarn be applied to the active force on thread-carrier when the braiding process.But this active force is relatively small, small clamping force also is enough to make the guide unit to be fixed on driving element thus.Do not exist between holding element and sley bar body and can make the frictional force of holding element with respect to the driving element displacement.
Preferred at this, make described guide element mounting board on driving element.If the guide unit is fixed on position desired on driving element, make two guide elements be clipped on driving element equally easily in left side and right side.This is relatively quick and simple fixed solution.

Especially as being seen by Fig. 3 and 4, described handle bar 6 can be rotatably set in handle bar section 7.This handle bar can prevent from moving axially in the mode be not shown specifically, and prevents from being parallel to it and moves longitudinally.
Described maintenance section 9 has clamping area 11 on the medial surface that is positioned at opening 10 opposites.The diameter that described handle bar 6 at least has two different sizes in the position of opening 10 (this position forms and clamps position), that is, less diameter D1 (Fig. 3) and larger diameter D2 (Fig. 4), they are misplaced 90 ° mutually.The diameter of handle bar 6 increases continuously in a circumferential direction, that is, the periphery of handle bar 6 forms by a circle spiral.
When handle bar 6 has been positioned at position of rotation, as shown in Fig. 3 and wherein less diameter D1 perpendicular to driving element 2, the distance between the periphery of handle bar 6 and clamping area 11 is greater than the diameter of driving element 2.Therefore holding element 8 can move by keeping section 9 on driving element 2, for changing its position.
When handle bar 6 has been positioned at it at the position of rotation shown in Fig. 4, at this, it compares half-twist with the position of rotation according to Fig. 3, and larger diameter D2 is perpendicular to driving element, and the distance between the circumference at opening 10 places of clamping area 11 and handle bar 6 is less than the diameter of driving element 2 slightly.Therefore driving element 2 is clamped between clamping area 11 and handle bar 6.
As being seen by Fig. 1, this makes driving element 2 be clamped in position between the maintenance section 9 of handle bar 6 and holding element 8 is exactly the position that the guide eye 5 of thread-carrier 4 is parallel to vertical extension of driving element 2.This position can easily be identified by operating personnel.Therefore can check on vision ground, whether guide unit 3 not only is positioned at but also is fixed on position desired on driving element 2.
Fig. 5 illustrates the modification structures of the variation of feed carrier, and wherein with function identical element identical with Fig. 1 to 4 is furnished with identical label symbol.
Described feed carrier 1 still has driving element 2, and it can by the wire with enough pressure rigidity or rope forms and can be called " tension/compression element ".Fixing guide unit 3 on driving element 2, guide unit 3 has thread-carrier 4, and thread-carrier 4 has guide eye 5, and guide eye 5 is fixed on handle bar 6.This handle bar 6 is connected with holding element 8, and this holding element has the cross section of U-shaped.Therefore holding element 8 has 12,13 and base limits 14 of two sides.Clamping area 11 is set on the medial surface of side 12.Corresponding clamping area 15 is set on the medial surface of side 13.Two sides 12,13 flexibly are arranged on base limit 14.Therefore clamping area 11 and corresponding clamping area 15 pretension in opposite directions flexibly.
Two sides 12,13 tilt slightly opposite to each other by its free end when removing driving element 2.When driving element 2 is arranged between two sides 12,13, make two sides 12,13 expand slightly away from each other, but only be expanded to such degree, their maximums are extended in parallel to each other.The elastic pressure be applied on driving element 2 by two sides 12,13 can not be extruded driving element 2 from holding element 8.
Described handle bar 6 is arranged on base limit 14.When driving element 2 is arranged in the groove of the sley bar body be not shown specifically, can makes guide unit 3 push up easily to press and can say that mounting board is on driving element 2 in desired position.The clamping force be applied on driving element 2 by clamping area 11 and corresponding clamping area 15 is enough to make guide unit 3 to be fixed on the desired position on driving element 2.Bear the active force brought by the yarn through guide eye 5 guidings at 3 of this guide unit need.
On two sides of guide unit 3, guide element 16,17 mounting boards are on driving element 2. Guide element 16,17 on gravity direction in the above and below protrude from holding element 8, and make between holding element 8 and sley bar body and do not have CONTACT WITH FRICTION.Therefore when driving element 2 moves in the sley bar body, do not have to make guide unit 3 to act between sley bar body and holding element 8 in the frictional force of driving element 2 superior displacements.Therefore guide unit 3 is remained on regulated position highly reliably.
