Definitions
- the invention relates to a Fadenaufhol device with a Fadenaufholarm.
- Fadenholzholvoriquesen were developed, which catch up the amount of thread that the distance from the thread guide parking position corresponds to the thread insertion position in the edge needle.
- the invention is based on the object, a technically simple Construction of a Fadenaufhol device to create, which nevertheless a reliable thread recovery guaranteed.
- a Fadenaufhol device with a Fadenaufholarm and a thread clamp for clamping the thread between a thread bobbin and a thread eye of Fadenaufholarms solved, the Opening and closing the thread clamp directly by the movement of the Fadenaufholarms is effected.
- the invention is the principle of operation of a Fadenaufhol device based on which each Fadenaufholarm a purely mechanically operating thread clamp is assigned, the closing and Opening movement is effected by Fadenaufholarm.
- the Fadenaufholarm comes in its pivoting movement to catch up to the limit of a fixed swivel range, it solves the closure the thread clamp off.
- the Fadenaufholarm comes in its pivoting movement for threading to this limit of the swivel range, so he opens the thread clamp and locks the opening position.
- the thread clamp causes its closing movement and its clamping force preferably self-sufficient.
- the Fadenholzholarm is no kinetic energy needed.
- a Fadenholzhol device 100 comprises a Aufholarm 1 and a thread clamp 2.
- Aufholarm 1 is a two-armed lever (first lever arm 11 and second lever arm 12) is formed, which is pivotally mounted at the pivot point 10 .
- the first lever arm 11 carries at the lower end of a thread eye 13 and is acted upon in the direction of arrow Z by a spring force.
- the second lever arm 12 cooperates with a thread clamp 2 and causes or opens the thread clamping.
- a thread 40 coming from a spool 30 passes a deflection point 41 and receives its tension on a thread brake 50 , passes through a thread breakage sensor 60, passes a deflection point 42, passes through the thread clamp 2, touches a deflection point 43, passes through the thread eye 13, passes one Turning 44 and is fed by a yarn guide 70 a knitting process 80 .
- This amount of yarn can make up for the Aufholarm 1 that the acted upon by a spring force in the direction Z
- the entire pivoting range SG is between the inner boundary 14 and the outer boundary 15. It divides into a region SL in which the yarn path from the spool 30 to the yarn guide 70 is not interrupted, and a region SF , in which the yarn 40 above the eye 13 of the Aufholarms 1 is jammed.
- the second lever arm 12 is connected via a hook element 7 with a latch 5 .
- the hook member 7 comprises with its annular end 71 a bolt 18 which is fixedly connected to the lever arm 12, and with its hook-shaped end 72 a bolt 53 which is fixedly connected to a bolt 5.
- the bolt 5 is horizontally displaceable in the directions of a double arrow 54 . Due to the shown position of the Aufholarms 1, the latch 5 has been pulled to its extreme left position. In the movement there, he has pivoted another lever 3 about an axis 31 in the position shown.
- the lever 3 is connected via a hook element 8 with a clamping slide 21 .
- the hook element 8 comprises with its annular end 81 a bolt 32 which is fixedly connected to the lever 3, and with its hook-shaped end 82 a bolt 23 which is fixedly connected to the clamping slide 21.
- the clamping slide 21 is horizontally displaceable in the directions of a double arrow 26 .
- the clamping slide 21 has been pulled to its extreme left position.
- a compression spring 24, which is supported on a surface 25 stretched.
- Fig. 2a is an end face with a clamping contour 22 of the clamping slide 21 in the open position to a rigidly arranged clamping piece 4.
- the passage for the thread 40 is so far that to be entangled threads 40 can be clamped in all thicknesses.
- the Aufholarm 1 is located in the transition region between the pivot areas SL and SF (see Figure 1).
- the second lever arm 12 has come to rest with its nose 17 on the end face 51 of the bolt 5 and moves it in the direction of an arrow 54 '.
- the force for the pivoting movement of the Aufholarms 1 comes from a spring 61 which exerts a pulling force on an arm 19 in the direction of arrow 62 .
- the arm 19, like the arm 12, is an arm located above the fulcrum of the recovery arm 1 designed as a two-sided lever.
- the Aufholarm 1 can its To perform pivotal movement in the area SF (see Fig. 1) and only has to overcome its inertia and the friction on the axis 9.
- FIG. 2 A second embodiment of the invention is shown in FIG .
- the position of a Aufholarms 1 ' and a terminal 2' correspond to the illustration in Fig. 2a.
- the terminal 2' is opened by the surface 17 'of the lever arm 12' or triggered their closing movement.
