Abstract
A kind of pin for knitting machine drives, and comprise driving claw, it has depression, in described depression, embed drive rod, and wherein compaction forces acts between drive rod and driving claw, wherein between driving claw depression and drive rod, forms the compaction forces acted on driving claw.
Description
Technical field
The pin that the present invention relates to a kind of knitting machine as according to the preamble of claim 1 drives.
Background technology
In the knitting machine of described type, many knitting needles are had to be loaded by public drive unit.Drive unit mainly comprises drive rod, and it is anti-rotationally connected with many levers, and these levers are driven by drive rod thus vibrate in rotation direction.Therefore the free end vibrating lever swings quiveringly with the angular range of about 25 degree, and the upper end of lever is connected with drive rod, and it extends usually in the whole machine length of knitting machine.
Therefore drive rod is correspondingly such as with the slewing area vibration that two ends are 25 degree.Drive rod is placed multiple parallel and driving claw be disposed adjacent.Connection between driving claw and drive rod is formed by the dished of opening wide on the rear end of driving claw, and driving claw surrounds the basic drive rod for circular contour at least in part, and the displacement realizing driving claw thus drives.
Driving claw itself is designed to the microscler handle parts be usually made of plastics, and is loaded with needle rack on leading section, and is provided with knitting needle on the leading section of knitting frame.
Needle rack is movably supported in two spaced sliding bearings, and wherein sliding bearing is contained in housings, and its position remains on knitting machine regularly.
In order to the position work making pin determine, it is known that arrange sincere son below needle rack, it forms rotatable hook, and the bottom surface making hook abut against driving claw at the position of rotation of the determination of sincere son thus pushes, and this makes it be disengaged with drive rod by its half depression of opening wide.Each driving claw can be made in this way to be disengaged with the drive rod of vibratory drive.
In order to avoid drive rod by mistake pulls out on the rear end of driving claw from half depression of opening wide, knownly by spring, driving claw is loaded like this, make it be remained under spring force on drive rod by its half depression of opening wide.
If driving claw therefore will be made to be disengaged with drive rod, the spring force of the spring pressing driving claw must be overcome, thus half of driving claw unlimited depression is disengaged with drive rod.
Press spring it is known in the art that described and be arranged on join domain between needle rack and driving claw.
This presses spring on needle rack, produces relatively violent, less desirable torque, and this makes the sliding bearing being attached to needle rack bear the power of tumbling in an undesired manner, which results in the sliding surface advanced wear of sliding bearing.
Especially can bring problem when high speed, because vibration is not only present on the mass axis of driving claw, the drive end depression of therefore surrounding the driving claw of drive rod partly may be disengaged with drive rod, thus causes danger.In order to avoid this point, must make to press spring and produce relatively large spring force, for ensureing that half of driving claw opens wide the positive engagement be recessed on drive rod.But spring force is larger, needle rack shell updip turn over or the danger of card rib inside the sliding bearing of subordinate also larger, and wearing and tearing also larger.
On driving claw, produce additional vibration and oscillation during this external high rotating speed, they have the trend that the depression of driving claw end is disengaged with drive rod equally.This also always needs larger spring force, and this is less desirable.
Summary of the invention
Therefore the object of the invention is, the pin improving the knitting machine of the above-mentioned type drives, under making the sliding bearing being attached to needle rack be in very small wearing and tearing.
In order to achieve this end, the invention is characterized in the technology instruction of claim 1.Dependent claims is favourable embodiment.
According to the present invention, the defect had realized that is, provide the half unlimited depression of pressing spring and driving claw of loading to arrange at intervals, consequent lever arm produces less desirable torque on driving claw with the needle rack be contained in inside driving claw.
Therefore according to the present invention, make half of driving claw to open wide the depression top compaction forces be pressed on drive rod and produce voluntarily and directly open wide the region of depression by be pressed in driving claw half.Avoid being arranged on the spring that presses leaving this recess thus and produce disadvantageous leverage.Also eliminate thus and be regarded as the disadvantageous torque of needle rack, and sliding bearing no longer carrys out prestrain with the tilting moment of needle rack.
Therefore key character of the present invention is, remove belong to prior art press spring, it not only applies to press torque on the drive end of driving claw in an undesired manner, but also additionally applies tilting moment or rotating torques in an undesired manner on the sliding bearing of the shell end of needle rack.Because press middle part or position, front end that spring is substantially disposed in driving claw, therefore not only produce in an undesired manner and press torque, and additionally produce tilting moment.
In a word, the invention describes three kinds of diverse ways, they are all for reaching identical object, namely remove the known tilting moment relevant to pressing spring and be only in half depression of opening wide at the drive end below of driving claw to produce compaction forces to drive rod.
Compaction forces herein, be between the depression of driving claw and drive rod at the drive end of driving claw and directly produce, and employ the drive rod without spring, this spring additionally produces tilting moment in an undesired manner on the sliding bearing of the shell end of needle rack.
All examples described below itself can both form patent separately and itself all advocates patent protection.Also relate to three independently patent requirements at this, they are all for identical object, that is, avoid increases wearing and tearing on the sliding bearing of the shell end of needle rack, therefore can not produce the tilting moment acted on sliding bearing.
Therefore in a preferred embodiment of the invention, be intended to remove spring and the substitute is directly on the drive end of driving claw, produce compaction forces.
According to first embodiment of the invention this compaction forces is designed to magnetic force, this means to be applied with magnetic force between the drive end and drive rod of driving claw, it makes two parts keep together with the form of permanent magnet.
Only mentioning the sincere period of the day from 11 p.m. to 1 a.m of driving claw due to operation, this magnetic-adsorption being cancelled, pressing sincere son by abutting against the sincere sub-bottom side of driving simply, make sincere son opposing magnetic force thus pull out from driving claw.
Therefore by applying this magnetic force, the advantage that has is because completely eliminated spring, therefore eliminate less desirable, as the tilting moment that must exist in spring solution above.Only be at the drive end of driving claw the driving claw being arranged at this cave in and produce compaction forces between drive rod.
In order to produce this magnetic compaction forces, there is different embodiments, and these can both obtain from content of the present invention.
In the first embodiment, described driving claw is made up of plastic material, and in described plastic material, such as, above the depression of driving claw, arranges one or more permanent magnet, and they produce compaction forces together with ferromagnetic drive rod.

In embodiment herein, two permanent magnets 22,23 are arranged side by side abreast, and the magnetic surface that it is polarized as far as possible closely is arranged on above depression 21, and therefore directly act on the excircle 27 of drive rod 7.
In depression 21, create the magnetic adsorbability between the drive end of driving claw 4 and the end face of drive rod 7 thus, and the less desirable torque 10 according to Fig. 1 prior art can not be produced.
Replace one or more permanent magnet 22,23 substantially flattened formed, bowl-shape permanent magnet can be used.
What replace this bowl-shape permanent magnet is the magnetic part that one pole also can be used to polarize, wherein even the magnetizable permanent magnet of the first one pole can be set on drive rod 7 end face and the magnet of opposite polarizations is set on opposed side, improving the magnetic adsorbability between driving claw 4 and two parts of drive rod 7 thus further.
In another embodiment of the present invention, magnetic force is replaced or what be combined with magnetic picture is put forward latching force.In figure 3, this point is shown.As can be seen from Figure 3, depression 21 is associated with a position, by making depression 21 extend on the angular range being greater than 180 degree and arrange latch projection 28 in this scope, it is connected with the lock flange 30 of elastic reaction, and it also has and enters inclined-plane 29.
Therefore, if drive rod 7 imports to inside depression 21 in the direction of arrow 48, before drive rod 7 joins to inside depression 21, first latch projection 28 must flexibly be overcome.
It is the locking connection of mechanism.
As mentioned above, being fastened and connected also additionally with the magnetic adsorbability shown in good grounds Fig. 2 to this mechanism.
Another locking shown in identical condition is also applicable in the diagram connects.Only illustrate, the excircle of 21 is unlimited and extends in the angle being not more than 180 degree, makes drive rod 7 easily be imported to inside depression 21 by its excircle 27 thus herein.
But on excircle 27, be provided with spring-loading locking ball 31, it abuts against corresponding bearing 33 by spring 32 and is biased, produce the latching force determined thus, and only could be disengaged with the excircle 27 of drive rod 7 in the condition lower recess 21 overcoming this latching force.
Also the embodiment according to Fig. 3 and Fig. 4 can be combined mutually.
Be bearing in movably inside the cross-drilled hole 34 on driving claw 4 end at this spring-loading locking ball 31.
Fig. 5 and Fig. 6 illustrates that connecting rod leads, and they are with magnetic suck or lock to be connected and work in combination, but also can advocate right of the present invention voluntarily.
Shown in Figure 5, the connecting rod 35 being fixed to shell forms the first embodiment of connecting rod guiding, and connecting rod defines bearing-surface 39 below.
If driving claw 4 is moved to the left on the direction of arrow 38, make the guide finger 36 be fixed on driving claw 4 side be bearing on the bearing-surface 39 of connecting rod 35 thus, the depression 21 of driving claw 4 can not be disengaged with drive rod 7.
But be likely drawn out at shown shift position driving claw, because guide finger 36 enters into the scope of the free position 41 on connecting rod 35 rear end, therefore whole driving claw can lift together with accompanying guide finger 36 in the direction of arrow 37, the driving claw engaged with drive rod 7 can be made thus to cave in and 21 to be disengaged with it.
Distance 40 between bearing-surface 39 and guide finger 36 means, guide finger 36 with certain gap on connecting rod 35 along slip.
Another embodiment of slide rail guiding shown in Fig. 6 A and Fig. 6 B, two different position of function shown in it.
In fig. 6, show in position 12, driving claw 4 can not be disengaged with drive rod 7.For this reason, drive pin 42 is connected with the central shaft 47 of drive rod 7 by the coupler 43 be not shown specifically, and inside the first guide rail 45 being embedded into the slide rail 44 of two bodies.
Therefore slide rail 44 is made up of the first guide rail 45, and the arc of movement 11 that it is basically parallel to lever 8 by its longitudinal axis is aimed at, and can not be disengaged thus at this position drive pin 42 with slide rail 44.
And in position 13, drive pin 42 enters the scope of the second guide rail 46, it is basically perpendicular to the extending longitudinally of the first guide rail 45, therefore can be disengaged with drive pin 42 at this position driving claw 4 and pull out.
The feature of all above-mentioned embodiments is, only in the drive end region of driving claw 4, the region be associated with the drive rod 7 of drive end in its depression 21 produces compaction forces or releasable attachment force, at sliding bearing 3a, 3b does not produce less desirable torque 10, therefore eliminate the wearing and tearing of these sliding bearings.
