Detailed description of the invention
The present invention is described in conjunction with the accompanying according to preferred design scheme below.Wherein:
Fig. 1 shows the very schematical diagram of the element of the tricot machine in the middle position of sley bar group, and
Fig. 2 shows the elements in the case where sley bar group overturn of Fig. 1.
Specific embodiment
Fig. 1 schematically shows some elements of tricot machine 1, wherein the longitudinal direction of the tricot machine 1 is perpendicular to label
Plane extension.
The tricot machine 1 has rack 2 and sley bar group 3.Multiple yarn guiding chase combs 4 are disposed at the sley bar group.It is described
Yarn guiding chase comb 4 carries yarn guide in a manner of not illustrating in greater detail.The yarn guide is successive perpendicular to the tag plane
Arrangement.The yarn guiding chase comb 4 and also the sley bar group 3 are correspondingly also with following longitudinal direction, perpendicular to institute
State tag plane extension.
The sley bar group 3 has by the mass cg 5 shown in cross.
The sley bar group 3 is hingedly supported at two supporting portions 6,7.Described two supporting portions 6,7 are along by double arrows
Continuous swaying direction shown in first 8 has spacing each other.
The supporting portion 6 is arranged at the first support component 9, and first support component is fixed on using articulation piece 10
At the rack 2.Second supporting portion 7 is arranged at the second support component 11, and second support component utilizes second
Articulation piece 12 is fixed at the rack 2.
Described two support components 9,11 tilt towards each other.In the middle position of the sley bar group 3, described two supports
Component 9,11 symmetrically arranges with one another, that is to say, that described two support components 9,11 sandwich respectively in reverse with the rack 2
Equal angle.The rack 2, the sley bar group 3 and described two support components 9,11 form trapezoidal herein.
The instantaneous centre of the support component 9,11 is in the mass cg 5 of the sley bar group 3.This passes through picture dotted line
Line is shown, and extends the support component 9,11.
Described two supporting portions 6,7 are arranged under following plane along gravity direction, the quality weight of the sley bar group 3
At the heart 5 in the plane.
As can be found out by comparing Fig. 1 and 2, the inclination of the sley bar group 3 can be as follows in a simple manner
Ground changes, and mode is that the support component 9,11 changes relative to the inclination of the rack 2.This change can for example pass through drive
Motivation structure causes, and the driving mechanism has tappet 13 in the ongoing illustrated embodiment, the tappet acts on described first
Support component 9.If the tappet 13 is moved along towards the direction of first support component 9, in first support component 9
Angle between the rack 2 increases.Because second support component 11 passes through the sley bar group 3 and first support
Component 9 couples, therefore the angle between the rack 2 and second support component 11 becomes smaller herein.Meanwhile described two
Obtained in the case where the angulation change of support component 9,11 movement of the translation of the sley bar group 3, in the case where current to the left
Translation.Because the sley bar group 3 tilts, therefore the yarn guiding chase comb 4 executes pendulum motion.The movement of the translation of the sley bar group 3
It is superimposed with pendulum motion.If described two support components 9,11 move in opposite direction, that is to say, that if in the machine
Angle between frame 2 and first support component 9 becomes smaller and between the rack 2 and second support component 11
Angle becomes larger, then the sley bar group 3 can move right and at the same time the yarn guiding chase comb 4 using its underpart end equally to
Right swing.
It is alternatively shown another driving feasible program: indicating that tappet 14, the tappet are not to make using the dashdotted line of picture
For a support component 9,10, but directly act on the sley bar group 3.Such tappet 14 can also pass through the warp
The main shaft of volume machine 1 drives.
The support component 9,11 can be formed by row's supporting element, and the supporting element is along the longitudinal direction side of the tricot machine 1
There is spacing to each other.That is, machine operator (Maschinenf ü hrer) has between the supports arrives warp thread
With the free entrance for arriving woven extent.
Because the sley bar group 3 is no longer supported at suspension hook axis (Geh ngewelle), old friend person is guiding the yarn
When with relatively large freedom.It need not consider further that the suspension hook axis or even crossbeam, the suspension hook axis are hung up at the crossbeam.
Some structure members are saved by abandoning suspension hook axis, the structure member can be that vibration is crucial
(schwingungskritisch), for example crossbeam, suspension hook axis, the rack top side walls or connecting rod.Thus real
Existing higher revolving speed.Simultaneously higher revolving speed can be realized with low cost.
Obtain compact structure.Thus, it is possible to use lighter structure member and lesser power occur.This is also helped again
In high revolving speed.
As mentioned above, realize that free yarn enters from top.Obtain short thread path and thus peace and quiet
Yarn enter.This causes good fabric quality in a simple manner.Furthermore comfortably gaiting for the yarn is obtained
(Einziehen).
Especially when the sley bar group is relatively heavy (because the sley bar group for example accommodates the guide comb of biggish quantity
Comb), then two dot points have the advantage that.Even if when the continuous pendulum motion must by biggish section carry out when (such as this
Such as in the braider of two-needle bar be that such situation is such), then two dot point also has the advantage that.
