Definitions

  • the invention relates to a bobbin for a braiding machine, comprising a bobbin, at least one brake system associated with the bobbin with at least one brake shoe and with a thread tensioning device which has at least one trigger associated with the brake system, each brake shoe and an associated actuator connected to each other via a pivot bearing are. Moreover, the invention relates to a braiding machine with a set of bobbins.
  • the brake system comprises a coil drum arranged on the brake drum with internal brake shoes.
  • the actuators are designed as rolling elements, which are spring-loaded on the flanks of a wedge designed as a trigger. Is in the thread tensioning device reaches a predetermined yarn tension, the wedge is moved so that the rolling elements on the flanks of the wedge roll and thereby release the brake shoes the brake drum.
  • the triggering paths to be carried out by the wedge must be as small as possible.
  • the invention has for its object to provide a clapper of the type mentioned, in which the adjustment of the brake system is simplified.
  • each brake shoe acts on the outside of a brake drum arranged on the bobbin, and that each actuator and the trigger are connected to each other via a sliding bearing.
  • the outside arrangement of the brake shoes advantageously allows a structurally simple placement of the sliding bearing.
  • sliding bearing bearings are here called bearings that have bearing parts that allow both translational and rotational movements between their sliding surfaces.
  • the translational freedom of movement serves to adjust the brake system, the rotational freedom of movement, however, serves to form a brake booster via suitable lever mechanisms.
  • the outside arrangement of the brake shoes combines the advantage of structurally simple placement of powerful lever mechanisms with the advantage of an open and easily accessible arrangement of the brake system associated Nachstellmechanismen.
  • the brake system has two brake shoes, wherein the hinged to the brake shoes actuators form a knee lever whose knee joint is the sliding bearing.
  • the actuators preferably each have the same length, so that a symmetrical toggle lever is provided.
  • the thread tensioning device has a trigger associated with the straight guide whose guide surfaces are aligned in the direction of the axis of symmetry of the toggle lever.
  • the guide surfaces are preferably part of the so-called locking slide, which is guided on a vertical guide rod of the bobbin according to the invention.
  • the hinged to the brake shoe actuator together with a support member forms a toggle lever, the knee joint is supported on a lever arm.
  • the support member is hinged to the bobbin, so that the knee joint of the toggle lever is pivotally supported on the bobbin.
  • Each pivotal movement performed by the lever arm is introduced via the knee joint in the toggle lever, wherein the spreading movement generated by the toggle lever is completely transferred to the one brake shoe.
  • the sliding bearing has a trained on the trigger axis and a trained on the actuator slot with which the actuator is mounted on the axis.
  • the respective associated rotary bearing facing reveal surfaces of the elongated hole form the sliding surfaces and the respective pivot bearing facing away from the cam surfaces from the driver surfaces.
  • the line section with which the slot can be moved on the axis center of the axis is hereinafter referred to as pivot line.
  • the fulcrum line thus corresponds approximately to the length of the elongated hole minus the diameter of the axis.
  • the automatic balancing or readjustment is realized by spring or weight forces which act on the actuators.
  • the actuators have on the trigger on upcoming sliding surfaces, with which the sliding rotational movement only by a force attack on the part of the actuators can be effected.
  • the actuators on the trigger on upcoming driver surfaces, with which a force application by the trigger in the sliding bearing causes only a rotational movement.
  • a sliding movement is transmitted directly to the pivot bearing via the driving surfaces of the actuators and causes the immediate opening of the brake shoes. Simplified shown, which is accompanied by wear of the brake pads change in position of the brake shoes with an automatic change in position of the actuators. In this way, the triggering path to be performed by the trigger remains constant regardless of the degree of wear of the braking paths.
  • the sliding rotational movements carried out by the actuators only lead within the braking system to an altered flow of forces whose effects on the braking behavior are negligibly small.
  • the sliding bearing has an axis formed on the trigger and a slot formed on the lever arm, with which the lever arm is mounted on the axle. With the lever arm on the trigger an improved force-displacement ratio is created. At the same time, a reduction in the actuating force to be provided by the trigger results in a reduction of the component loads within the clapper according to the invention as a whole.
  • each of the pivot bearing passes through and the longitudinal axis of the associated elongated hole right angles passing radials outside the fulcrum line of the sliding bearing. Too small a distance of the radial to the pivot line may cause wedging of the actuators with the axis of the trigger.
  • the toggle lever is advantageously designed such that the longitudinal axes of the elongated holes in each position of the sliding pivot bearing form a crossing point with each other.
  • This crossing point assumes a V-shape in the start and in the end position of the sliding bearing.
  • the longitudinal axes of the elongated holes extend substantially in the direction of the axis of symmetry of the toggle lever and intersect only at a small angle, preferably an angle between 0 and 10 degrees.
  • the axis of the shutter is included in each position of the sliding bearing in the crossing point of the slots. A trip magnifying game can thus not arise.
  • the braiding machine according to the invention is characterized in that at least one of the clappers is a clapper according to the invention. However, preference is given to all bobbins of the braiding machine according to the invention.
  • the clappers of a sentence can be executed to each other both different and identical.
  • FIG. 1 shows a partial perspective view of a bobbin for a braiding machine according to the invention in a first embodiment.
  • the clapper is essentially composed of a bobbin 1, a brake system 2 associated with the bobbin 1 with two brake shoes 3, 4 and a yarn tensioning device 5 together.
  • the thread tensioning device 5 has a trigger 6 assigned to the brake system 2.
  • the brake shoes 3, 4 are each connected via a pivot bearing 9, 10 with an actuator 7, 8 and the actuators 7, 8 are connected via a sliding bearing 11 with the trigger 6.
  • the sliding bearing 11 is designed as a knee joint, the knee lever are hinged to the brake shoes 3, 4 actuators 7, 8.
  • the sliding bearing 11 has an axis formed on the trigger 6 axis 12 and formed respectively on the actuators 7, 8 elongated holes 13, with which the actuators 6, 7 are mounted rotatably mounted on the axis 12.
  • the thread tensioning device has a locking slide 14 which is guided in the direction of the axis of symmetry of the knee lever formed by the actuators 7, 8.
  • the locking slide 14 serves as a guide for a cocking slide 15 arranged on it.
  • the brake shoes 3, 4 are articulated by means of bearing bolts 16, 17 on the base 18 of the bobbin and on their sides facing away from the bearing pin 16, 17 sides by means of a tension spring 19 against a brake pad of a ratchet wheel pulled, which is placed on the ball bearing 20.
