Abstract
A yarn-braking device for weaving machines comprises a main housing supporting a triad of yarn-guide eyelets through which passes a weft yarn, and a U-shaped braking member which is fastened to motor means and is arranged astride of the middle eyelet. The braking member engages the yarn in its free lengths between the middle eyelet and end eyelets, thereby causing the yarn to be braked. The end eyelets (32,36) are held by respective axially translatable supports which are lockable at predetermined axial positions.
Description
Technical field
The present invention relates to a yarn arresting gear that is used for loom.
Background technology
One known brake apparatus, as with described in the italian patent 01303154 of applicant's previous industrial invention, it comprises ternary fixing, coaxial guide eye, and yarn passes all guide eyes, and the yarn on the span between the guide eye is followed the path of a straight line.One rocking bar is fixed to a U type brake component, and guide eye was installed in the middle of this brake component strode across, and with in braking procedure, engaged yarn on the drift between guide eye and the both ends guide eye therebetween.Bar is connected on the connecting rod of the linear motor that makes its swing in operation.Bar causes the braking that causes because of frictional force by departing from yarn from its straight line path.
Though this known devices basis provides an appropriate responsive to the rapid reacting condition of the mechanical tension of yarn, yet its adaptability to dissimilar yarns is not fully up to expectations.In fact, " drying " degree according to yarn can allow stronger or more weak braking action.
Summary of the invention
Therefore, a main target of the present invention provides the yarn arresting gear that can regulate according to yarn types that is used for loom, like this, can provide stronger or more weak braking action according to the characteristic of yarn.
Another target of the present invention provides a kind of device of can be easily and regulating apace.
The present invention also has a target to provide a kind of device, and its manufacturing is inexpensive and easy, and by means of the known technology and the equipment that generally use in the present technique field, can realize making.
The objective of the invention is to be achieved through the following technical solutions, one yarn arresting gear that is used for loom is provided, it comprises the main casing of the guide eye that the ternary weft yarn of a supporting passes, an and U type brake component that is fixed to motor, guide eye was installed in the middle of this brake component strode across, with in braking procedure, engage yarn with the drift between middle guide eye and both ends guide eye, cause yarn to be braked by frictional force thus, wherein, but at least one end guide eye is by the supporting members support of an axial translation, and supporting member may be locked on the predetermined axial position.
Brief description of drawings
The present invention is existing to carry out comparatively detailed description with reference to a preferred non-exclusive embodiment, and embodiment illustrates by means of limiting examples in the accompanying drawing, wherein:
Fig. 1 one is equipped with the side view according to the weft feeder of brake apparatus of the present invention;
Fig. 2 is the brake apparatus of Fig. 1 is set at the heavy braking effect in operating process a stereogram;
Fig. 3 is the enlarged side view as the brake apparatus of Fig. 1 of Fig. 2 setting;
Fig. 4 is the brake apparatus of Fig. 1 is set at soft braking action in operating process a stereogram;
Fig. 5 is the enlarged side view as the brake apparatus of Fig. 1 of Fig. 4 setting;
The specific embodiment
With reference to Fig. 1, a common weft feeder 10 comprises a stationary cylinder 14 attached motor casings 12 thereon.By a turning arm 15 that is contained in the electric motor operated in the motor casing 12 a large amount of yarn coil F is entangled on the stationary cylinder 14, forms a weft yarn tube thus.
One brake apparatus 20 (being shown in further detail in Fig. 2-5) is on the end 22 of the fixed arm 16 that be bearing in the axis of secured in parallel cylinder 14, stretches out from motor casing 12.For brake apparatus being fixed to arm 16, the end 22 of arm is radially towards the axis bending of stationary cylinder 14, and supporting will install the hollow stud 24 of 20 main casing 26 clampings.For this purpose, main casing 26 has a cylindrical cavity 28, and the diameter of its diameter and stud 24 mates, and the positioning seat of stud is provided.The wall of cylindrical cavity 28 has an opening 30 longitudinally, and brake apparatus 20 is fixed on the stud 24 by a trip bolt, and trip bolt inserts in the tangential hole 82 on opening 30 edges, and with a respective screw hole engagement at the offside edge.
According to the present invention, a pair of screw- thread bush 42,46 of supporting end guide eye 32,36 separately is bearing on the relative left-hand thread end of axle 44, and axle is bearing on the support 48 that is attached to main casing 26 pivotly about the intermediate portion.Middle guide eye 34 is fixed to support 48.A pair of clasp 60 is installed on the axle 44 of support 48 opposite sides, with locking spindle axially.Connecting rod 54 parallel axles 44 also constitute with middle guide eye 34 one, and the end of bar 54 engages with hole separately on the neck 52,56 that is formed on end guide eye 32,36, and the neck of guide eye connects guide eye to separately lining 42,46.Connecting rod 54 is suitable for guiding 32,36 translations of end guide eye and prevents its rotation.The head of axle 44 has a groove 50 that can engage with the screw driver (not shown), to regulate the position of guide eye.
By operation axle 44, can change the axial distance between the guide eye, like this, can regulate the skew that provides by U type brake component 58 and whole braking action in succession.
Have found that in practice by a weft yarn brake apparatus is provided, it can be provided with powerful or soft braking action according to yarn types, the present invention can solve above-mentioned target.In addition, by a plain screw bottle opener or other proper tools, this brake apparatus can be easily and quick adjustment.This is conspicuous to masterful technique personage in the present technique field.
Can make the remodeling of different modes within the scope of the invention to embodiment described here, and all details replaceable be other technical equivalents thing.For example, axle 44 can be provided with a knob to be easy to the adjusting of device.In addition, the masterful technique personage, it is evident that in the present technique field that connecting rod 54 is replaceable to be suitable for the location guide that stops the end guide eye to rotate with respect to main casing around the axle axis for other.The rotary motor 40 of brake activation spare 58 is replaceable to be one to be provided with the linear motor of type described in the above-mentioned existing patent of mentioning and the assembly of connection.
In practice, as long as material that uses and concrete purposes are compatible, so as required, material and size and dimension thereof can be inequality.
