Definitions

  • the invention relates to a braiding block for a braiding machine, with an eye guiding the braid to be pulled off, which is designed as an insert held in a cold, which is operatively connected to a switch for interrupting the operation of the braiding machine.
  • Threads drawn from the individual bobbins of a braiding machine are combined in the so-called braiding point to form the braid to be drawn off.
  • Braid cleats serve to fix the braiding point.
  • the braiding point is located just below the braid and the braid is continuously drawn off by the braid's eye.
  • Braiding machines with plaice are described in DE-C-49 512 and DE-A-1 660 001.
  • a knot thicken the braid to such an extent that it could only be pulled through the eye of the plait with considerable resistance. If the braid, or the insert, is kept movable, the resistance can be used to convert it into a movement by which an organ that interrupts the operation of the braiding machine, e.g. an electrical switch that can be actuated.
  • the triggering of the interruption in operation by the plait must be adjustable.
  • the one with the eye Use is therefore held in a holder in the case of known braiding blocks with corresponding adjusting elements, for example springs with tensioning screws.
  • the invention has for its object to improve a braid so that an easier and less expensive replacement of an insert is possible.
  • the holder consists of two side by side and the insert between receiving parts, which can be pressed against each other with at least one adjustable with respect to the applicable clamping forces clamping member, the parts are connected to each other like a pliers jaws.
  • a holder reduced to two parts, which can be attached to a braiding machine above the braiding point with any desired fastening means, can advantageously be quickly dismantled, for example in order to be able to replace the insert accommodated between the parts.
  • the two parts of the holder are pressed against one another with the tensioning element, so that the insert is clamped between the two parts.
  • the clamping forces holding the insert are generated by the clamping element. Since the clamping forces that can be applied by the clamping element are adjustable, use with low clamping forces is clamped between the two parts of the holder in a relatively easily movable manner. At higher clamping forces, the stiffness of movements of the insert relative to the parts of the holder increases. Because movements of the insert are used to To actuate the switch for interrupting the operation of the braiding machine, the sensitivity of the triggering of an interrupted operation can be adjusted by the clamping forces.
  • Replacing inserts is further facilitated in that the parts are jaws which are connected to one another in a pincer-like manner.
  • the parts are jaws which are connected to one another in a pincer-like manner.
  • the parts designed as pliers-like jaws can both form the "loose jaws" of a pair of pliers.
  • a preferred embodiment provides for a “fixed jaw” and a “loose jaw", the fixed jaw being connectable to the machine frame of the braiding machine and advantageously also other attachments, e.g. the interruption switch, from which the fixed jaw can be carried.
  • the clamping element has a spring that compresses the jaws. Springs are preferred because their preloading can be reduced with little construction effort by appropriate adjustment means, e.g. structurally simple clamping screws, easy to adjust.
  • the clamping member comprises a rod which is held at one end at a jaw end, that the rod through the second The end of the jaw extends through and that a section of the rod protruding from the second end of the jaw carries a spiral compression spring which is supported in the region of the free end of the rod on a rod shoulder and whose spring end facing away from the support side rests on the outer surface of the second jaw.
  • the arrangement is such that the rod is designed as a pivot lever mounted in the second jaw.
  • the opening and closing of the parts of the holder designed as pliers-like jaws is further facilitated in that the jaw end of the first jaw is fork-shaped and that the end of the rod which extends through the fork ends has a stop head spanning the fork.
  • This design has the advantage that an adjustment of the clamping member is not necessary to open and close the holder consisting of pliers-shaped jaws.
  • the tensioning element remains set so that a tensioning force that has been set once acts on a new insert even after the replacement of an insert.
  • the sensitivity that is to say the response threshold of the operational shutdown, can also be set in the braiding clod according to the invention, but the sensitivity which has been set remains even after the inserts have been replaced.
  • the adjustment of the sensitivity of the response to an operational shutdown by movements of the insert relative to its holder is very simple in that the rod shoulder is designed as a screw stop seated on a threaded section of the rod.
  • the screw stop can be used for adjustment the pre-tension of the spiral compression spring can be used, whereby the screw stop can be secured, for example by a lock nut, in the respectively set position.
  • the insert is spherical in shape with a hole forming the eye and the jaws forming the holder have pan-shaped recesses.
  • the insert can move relatively freely with respect to the jaws forming the holder, and these movements can be used to actuate a switch.
  • a side pull e.g. by means of a stiff clapper
  • the insert in the pan-shaped recesses is twisted when the static friction between the insert and the pan-shaped recesses in the jaws forming the holder is overcome.
  • the static friction can in turn be adjusted by the pressing force of the tensioning element.
  • the braiding machine can be interrupted when the insert moves in the pan-shaped recesses.
  • a simple actuation of a switch is possible in that the spherical insert has a radial flange surrounding the upper opening edge of the eye.
  • the radial flange forms the extension of the insert projecting into the actuation area of one or more switches with the particular advantage that not only tilting movements of the insert, such as occur, for example, when pulling sideways due to stiff clappers, can be used to interrupt the operation of the radial flange, but it is also It is possible, for example in the case of knot formation, in which the braid to be pulled off would no longer be able to be pulled off by the eye, to use an entire raising of the insert relative to the holder.
  • a swivel bracket is mounted on the outside of the jaw, which is bent in such a way that it is in front of the lower one Opening edge of the eye in use runs and ends in the range of movement of the actuating plunger of a switch.
  • the switch can be a switch assigned to the bracket. However, it is also possible to let the bracket act on the same switch that is also assigned to the radial flange of the spherical insert.
  • a single switch is advantageous as a breaker usable for a braiding machine if the switch has an actuating plunger that can be moved in four directions, for example, switching movements can be carried out horizontally back and forth vertically up and down at the same time.
  • the bracket can also be bent to an eyelet surrounding the thread inlet area in front of the eye of the insert, as a result of which the braiding point can also be monitored with regard to a side pull, thread break or the like.
  • the advantages of the braiding block according to the invention are that the split design with two jaws makes it easier to change the insert, and the special design of the tensioning element in connection with the pincer-shaped jaws of the holder enables a response threshold to be set once the braiding machine has been out of operation, so that adjustment work can be carried out are no longer required after each replacement.
  • One and the same holder can be used for inserts with different eye diameters.
  • the plait according to the invention is suitable for simultaneously monitoring several criteria in which a business interruption has to take place, e.g. Side pull due to stiff clapper, knot monitoring and monitoring against sagging of the braiding point.
  • FIG. 1 shows a top view of a plaice.
  • the essential component of the plait is the insert 1, which has an eye 2 that guides the braid to be pulled off.
  • the insert 1 is held in a holder 3.
  • the holder 3 can be attached to the machine frame of a braiding machine (not shown further here).
  • the holder 3 consists of two parts 4 and 5.
  • the parts 4 and 5 are designed as jaws which are connected to one another by a hinge 6, the part 4 being a "loose jaw” and part 5 being a "fixed jaw”.
  • the clamping member 7 comprises a rod 8 which is held at one end 9 on a jaw end 10 of the part 5 forming the first jaw.
  • the jaw end 10 of the first jaw is fork-shaped, the end 9 of the rod extending through the fork ends having a stop head 11 spanning the fork.
  • Part 4 is the second jaw, through the jaw end 12 of which the rod 8 extends.
  • the section of the rod 8 protruding from the second jaw end 12 carries a spiral compression spring 13 which is supported on a rod shoulder 15 in the region of the free end 14 of the rod 8.
  • the end of the spiral compression spring 13 facing away from the support side lies against the outer surface of the jaw end 12 of the part 4 which represents the second jaw.
  • the rod is designed as a pivoting lever which is pivotably mounted in the jaw end 12 in the bearing point 16.
  • the rod shoulder 15 is designed as a screw stop 17 seated on a threaded section at the end 14 of the rod 8, using a nut and a lock nut for this purpose, as shown here.
  • the part 4 of the holder 3 can be swung from the part 5 by pivoting about the joint 6 in order to insert the insert 1 e.g. exchange.
  • the rod 8 is pivoted about the bearing point 16, the handle 18 being moved to the left.
  • the stop head 11 moves to the right, the upper section of the rod 8 disengaging from the fork-shaped jaw end 10.
  • the part 4 can then be folded down and the insert 1 is accessible.
  • part 4 can be folded back.
  • the rod 8 is pivoted back, the end of the spiral spring 13 resting against the arc-shaped outer surface 19 being moved back into the position shown here by deflecting the spring.
  • the spiral compression spring 13 then again has the pretension previously set by means of the screw stop 17, with which the two parts 4 and 5 are pressed against one another while the insert 1 is clamped.
  • the actuating plunger 21 is movable in the horizontal direction of the double arrow 22 and in the vertical direction of the double arrow 23 (FIG. 2).
  • the actuating plunger has a head-like thickening 24 at its free end, with which it protrudes into the range of motion of a radial flange 25 surrounding the upper opening edge of the eye 2 of the insert 1.
  • a pivot bracket 26 is mounted, which is bent such that it runs in front of the lower opening edge of the eye 2 in the insert 1 and ends with its head 24 in the range of movement of the switching plunger 21.
  • Fig. 2 shows a front view of the plait in a cross section, in which the part 4 to be viewed as the second jaw is largely not visible.
  • Fig. 2 shows that the insert with its upper radial flange 25 is spherical and with a bore forming the eye 2 and that the cheek-shaped parts 4 and 5 forming the holder 3 have pan-shaped recesses 27, so that the spherical insert 1 is accommodated in the recesses so as to be movable on all sides as in a joint.
  • Fig. 2 also shows the course of the bracket 26, as well as the fork-shaped design of the jaw end 10, through which the end of the rod 8 engages, which has a stop head 11 spanning the fork.
  • Fig. 3 shows a side view of the plaice. The same components are labeled with the same reference numbers.
