Definitions

  • the invention relates to a device for producing cat head nodes, in particular for creel, with an insertion device for positioning two parallel thread ends on the knotter, which are overlapped by a binding beak with an L-shaped beak hook and are gripped by the beak hook end each time the rotating driven binding beak passes , whose beak hook is provided with a correspondingly L-shaped, movable scissors half, which cooperates at one control end with a link controlling the opening and closing of the binding pin forming a thread clamp, which is adjustable according to the rotational position of the binding beak.
  • Bobbin creels have a large number of bobbins which must be re-equipped after the threads of the bobbins have been unwound.
  • the so-called cat head knot is primarily used as the knot, which is comparatively simple, but is therefore easy to manufacture and which has usually grown only when the threads are warmed, without opening.
  • the knotters used to manufacture it are comparatively simple. They essentially consist of a rotary-powered binding bill, which has the features mentioned at the beginning.
  • a fixed backdrop which acts on the control end of the movable scissor half and thereby opens the binding beak.
  • the opened, rotationally driven binding beak overlaps the parallel thread ends and cuts them off when the control end leaves the backdrop.
  • the thread ends are clamped at the same time.
  • the fixed backdrop causes the binding beak to be opened and closed with every complete revolution.
  • an additional gripper must be provided to keep the thread ends out of the area of the snapping binding beak when the thread ends are not to be gripped.
  • Such a gripper control is complex.
  • the link is arranged as a transverse part between two parallel pivot arms, which are pressed by spring force onto a control cam, which lifts the link at the desired time and thus creates the possibility that the control end of the movable scissor half engages can get with the control contour of the backdrop. Since the swivel arms move on a circular path around the swivel axis, the backdrop moves accordingly. As a result, it cant relative to the control end of the movable half of the scissors.
  • the invention has for its object to improve a device with the features mentioned so that it can be constructed more easily and works more reliably.
  • the backdrop is arranged in a control slide that can only be adjusted in one plane. It is essential for the invention that a pivoting movement of the backdrop is avoided.
  • the control slide which is adjustable according to the invention only in one plane, obviously enables a simple degree guidance of the link, so that tilting of the link relative to the binding bill is excluded. As a result, there are no functional uncertainties in the knot caused by tilting of the backdrop.
  • the control slide is a circular plate with a front plate of a housing for the Rotary drive of the binding beak, which is vertically displaceable in the sliding guide of the housing.
  • the use of the front plate for the formation of the backdrop is a significant simplification of the knotter, the vertical displacements occurring only in one plane being reliably controlled by the sliding guides of the front plate.
  • the control slide has a cam bolt which interacts with a control cam parallel to the control slide, which is adjusted by the rotary drive.
  • the required adjustment of the control slide corresponding to the rotational position of the binding spigot is carried out by the cam pin and the control cam via a positive connection which precludes lifting of the two components from one another as a result of the actuating forces of the binding spigot.
  • the necessary assignment between the beak function and control curve is therefore always guaranteed.
  • control cam is arranged coaxially with a gear wheel of the rotary drive directly behind the control slide and placed on the gear wheel.
  • the rotary drive of the binding bill has an input shaft acted upon by a swivel lever, an axially parallel intermediate shaft driving the control cam relative to the input shaft and an axially parallel binding bill shaft acted upon by the latter.
  • the rotary drive can therefore be made comparatively compact while ensuring the required ratio between the input shaft and the binding bill shaft and only requires simple structural and cost-effective parts with which the production outlay can be kept low.
  • the side walls of the housing for the rotary drive form the insertion device of the knotter with protruding insertion plates with insertion slots on the front.
  • the insertion device can therefore be manufactured as an integral part of the side walls of the housing, which are required anyway, by punching for mass production.
  • the thread knot 15 has a housing body 17, the side walls 17 'of which are a front insertion plate 18 and a rear insertion plate 19 with insertion slots as shown in the drawing as insertion means for the thread ends 16 3 form.
  • a binding beak 20 essentially consists of a beak hook 21, which is essentially L-shaped and overlaps the thread ends 16 inserted into the insertion device.
  • the beak hook 21 is arranged on a binding beak shaft 20 'in a rotationally fixed manner via two pins, which are not designated in any more detail and which allow the beak hook 21 to be adjusted relative to the thread ends 16 located in the insertion device.
  • the binding beak 20 from a movable pair of scissors 22, which is the L-shaped corresponding to the beak hook 21.
  • the L-shaped beak hook 21 of the binding beak 20 consists, in a manner known per se, of two pieces of sheet metal arranged at a distance from one another, as can be seen for example in FIG. 8. Between the two pieces of sheet metal, the movable scissor half 22 is arranged, which forms a pair of scissors with the beak hook 21, but which at the same time also forms a thread clamp in a conventional manner.
  • the binding beak 20 is rotatably mounted with its binding beak shaft 20 'in bearing bushes 31, 32 of the housing body 17 and secured in position with a locking washer 33.
  • An intermediate shaft 27 is rotatably mounted in bearing bushes 34, 35 and secured in position with a locking washer 36 parallel to the axis of the binding bill shaft 20 'and to an input shaft 29.
  • the input shaft 29 is supported in bearing bushes 37, 38 and carries at its rear end a pivoting lever 30 which sits on the input shaft 29 in a rotationally fixed manner with a pin 39 and, when subjected to a corresponding action by an actuating rod, can rotate the input shaft 29.
  • All the gears form a transmission ratio, which accordingly results in a pivoting angle of the pivoting lever 30 of 60 °, for example a rotation of the binding bill shaft 20 'by approximately 850 °.
  • control end 22 ' At the end of the movable scissor half 22 there is a control end 22 ', namely essentially a lower A web arranged to the right of the binding bill shaft 20 ', which is arranged with its web ends 22 ", 22""within a circular link 23" of a control slide 23.
  • the web ends 22 ", 22"" engage with the link 23', each after which position the control slide 23 assumes relative to the binding bill 20.
  • the position of the control slide 23 is determined as a function of the rotational position of the binding beak 20.
  • the spool 23 has a cam pin 24 which interacts with a cam 28.
  • the control cam 28 is arranged coaxially with the gear 27 ′′ of the rotary drive and is located directly behind the control slide 23 on the gear 27 ′′.
  • a rotation of the gearwheel 27 ′′ and thus of the rotary drive causes the control cam 28 to be rotated accordingly.
  • the cam contour 28 ′ which projects radially in comparison to the cam contour 28 ′′ of the control cam 28, causes the cam bolt to be driven after a corresponding rotation of the intermediate shaft 27 -Zens 24 and thus a lifting of the control slide 23. This is vertically displaceable in sliding guides 25, 26 of the housing.
  • the thread ends 16 are first driven into the slot of the insert plate 18 and then into the slot of the insert plate 19 from below.
  • the slots are shaped so that the thread ends 16 inevitably come behind the L-shaped beak hook 21. If the binding beak 20 is now rotated by pivoting the pivoting lever 30, its beak hook 21 engages behind the thread end 16 according to FIG. 4 and, when the binding beak shaft 20 'is turned further, forms a loop as shown in FIG. 5 after a further half turn. Here, too, it engages behind the thread ends 16.
  • the thread loop formed in the process is further rotated during the next half turn of the binding beak until the position shown in FIG. 6 of the binding beak 20 is reached.
  • the curve contour 28' comes under the cam bolt 24 and lifts the control slide 23. From then on, the control end 22 'of the movable scissor half 22 no longer has enough space to move without contact within the link 23'. Rather, it touches this link 23 'with the web end 22 "and thereby pushes upwards or swivels the movable scissor half 22 outward, so that the binding beak 20 opens. As a result, the binding beak 20 overlaps the thread ends 16 with the L-shaped beak hook 21 on one side and with the movable scissor half 22 on the other side of the thread ends 16 according to FIG.
  • the thread ends 16 on the spool or thread brake side are tightened, so that the thread loop 16 'is tightened, as shown in FIG. 11.
  • the thread ends 16 are pulled out of the binding beak 20 or the binding beak 20 opens in that the web end 22 ′′ runs into the area of the opening contour of the link 23 ′. Then the unwinding process can be continued from the creel because a sufficiently tight knot has been created, namely a double cat head knot.
  • the knotting device is then reset by swiveling back the pivoting lever 30 so that the binding beak 20 or the binding beak shaft 20 'return to the starting position shown in FIG. 3 and are ready for a new knotting process.
  • the knot formation takes place during 2 1/4 turns of the binding beak.
  • a double cat head is made.
  • the same device to produce single or more than double cat heads, in which the binding bill feed is changed. It must therefore be ensured that the binding bill shaft 20 'only makes half a turn or 2 1/2 turns before the control slide 23 is raised before the binding bill 20 opens to produce a triple cat head. This is easily possible by choosing the starting position of the pivot lever 30.
  • the control slide 23 is reset during the return of the binding bill by restoring forces of the movable scissor half 22 after the control cam 28 has released the cam pin 24.
  • the advantage of the thread knotter according to the invention is therefore also that it can easily produce single or multiple cat head knots, so that, for example, even threads with at least double cat head knots are knotted and are therefore sufficiently durable.
