Definitions
- the invention relates to a device for producing a strip with a curvature, in particular a curved flat line assembly, consisting of several pairs of clamping jaws connected downstream of a weaving device for pulling off the individual lines.
- the movable hook In order to weave a curve, the movable hook is closed and clamps the warp threads while the fixed hook is open. Then, the movable looper clamp is moved about a fulcrum, with the result that the warp threads of the composite fabric are moved by an amount increasing from the edge close to the fulcrum towards the edge of the looper clamp from the fulcrum in each cycle. There is a curvature in the fabric composite towards the side of the shorter warp threads. At the end of the movement, the fixed gripper clamp is closed and the movable gripper clamp is opened, and this goes back to its starting position against the pulling direction.
- the sequence of movements is periodic. There is a curvature, the radius of which results from the distance of the fulcrum from the warp threads and the sense of which results from the position of the fulcrum on the right or left of the warp threads.
- the movable gripper clamp is moved in a straight line for the production of straight pieces.
- the disadvantage of this device is that the withdrawal is jerky in that the transport of the warp threads has to be stopped abruptly when the movable gripper clamp moves back into the starting position.
- the invention has for its object to achieve an approximately uniform movement of the warp threads.
- the object is achieved in that all pairs of jaws are movable and driven and pivotable along the withdrawal direction.
- two pairs of clamping jaws are arranged, which can alternately move back and forth along the withdrawal direction by means of drives acting on the ends of the clamping jaws, the amplitude of the movement being independently variable on both sides.
- the drive device can preferably be a crank drive system, a crank drive engaging on each side of each clamping jaw and the stroke of the crank drives on one side being adjustable relative to the stroke of the crank drives on the other side.
- a plurality of clamping jaws are arranged on one or more pairs of driven endless rotating non-stretchable drive means in such a way that the clamping jaws face each other in pairs.
- the clamping jaws have start-up cams with an oblique start-up area.
- thrust rollers are arranged, which can be pivoted into the movement path of the thrust cams.
- Elastic return elements in particular coil springs or leaf springs, are preferably arranged between adjacent clamping jaws.
- the inextensible drive means are preferably roller chains or toothed belts.
- the device according to the invention it is possible to use a wide variety of materials as warp threads in order to meet the most varied requirements of the client.
- insulated copper lines, hoses for conveying media and for pneumatic and hydraulic systems, reinforcing threads made of cord, steel, carbon or the like, light guide cables and similar materials can be used as warp threads.
- the radii of curvature can be set within a wide range, which does not depend on the width of the jaws. It is e.g. B. possible to manufacture the corresponding flat cable harnesses to meet the requirements of the aerospace and automotive industries.
- FIG. 1 is a side view of a device with crank drive according to the invention
- FIG. 1 shows the top view from FIG. 1,
- FIG. 3 shows the working principle of the trigger device according to FIG. 1,
- Fig. 5 is a side view of Fig. 4 and
- Fig. 6 the pivoting of the jaws in the puller with chain drive.
- Fig. 1 shows a device according to the invention in side view in a ribbon loom. It has four jaws 1, 2, 3, 4, two of which are each are arranged in pairs. The individual lines 5, which act as warp threads of a line assembly, run between the pair of clamping jaws. Each clamping jaw is guided in a guide 6 indicated by dashed lines. At each end of each jaw, connecting rods 7, 7 ', 8, 8', 9, 9 '10, 10' cranks 11, 11 '12, 12', 13, 13 '14, 14' engage (Fig. 1 and Fig . 2). The connecting rods 8 'and 10' and the cranks 12 'and 14' are not visible.
- the cranks of the upper jaws 1, 3 are driven by the upper shaft 15 and the cranks in the lower jaws by the lower shaft 16. There is an offset of 180 ° between the cranks 11, 11 ', 12, 12' for the front jaws 1, 2 and the cranks 13, 13 ', 14, 14' for the rear jaws.
- the weft insertion 17 is located in front of the front clamping jaws 1, 2 (cf. FIG. 2).
- the device works as follows:
- the upper shaft 15 is set in motion clockwise and the lower shaft 16 in the counterclockwise direction.
- the pairs of the front jaws 1, 2 and the rear jaws 3, 4 move alternately towards and away from one another on the guides 6.
- the connecting rods on the left 7, 9 have a smaller amplitude than the right connecting rods 7 ', 9' with the longer crank 11 ', 13' due to the shorter crank 11, 13.
- An initial position and (indicated by a fine line) an end position within a half-period from 0 to ⁇ is shown for each pair of jaws.
- the right individual lines are drawn off with a greater length than the left.
- a curvature results from the size of the difference in the radius of curvature.
- the line network is curved by ⁇ with each period. The sense of curvature is determined by the side on which the amplitude is set to smaller values compared to the opposite side.
- the drive device and the clamping device are designed in such a way that the curved line assembly can easily emerge from the side.
- the clamping jaws can be profiled in accordance with the diameter profile of the individual lines.
- FIG. 4 shows the lower part of a pull-off device with a roller chain drive.
- This has a lower chain 18.
- the clamping jaws 19 are pivotably mounted on the lower chain 18 at a uniform distance. They are connected to one another by spiral springs 20 and are supported on a pressure track 21.
- the starting cams 22, 22 ' are located on the outside of the clamping jaws. They have an inclined and curved contact surface. Thrust rollers 23 which can be pivoted into the movement range of the starting cams are arranged on the right and left.
- the individual lines 5 (FIG. 5) run over the lower part of the extraction device.
- Fig. 5 the upper part of the trigger device is arranged in mirror image.
- the upper chain 24 with the upper clamping jaws 25, which are supported on the upper pressure track 26, is visible.
- Lower jaws 19 and upper jaws 25 are arranged opposite one another on the chains.
- the chains run in the pull-off direction. They apply the linear pull-off force for the individual lines.
- the start of the clamping is fixed by the two pressure tracks 21, 26 on which the clamping jaws 19, 25 run. They are set up in such a way that, as shown in FIG. 5, the individual lines are clamped on the clamping line 27 between the upper clamping jaws 19 and the synchronously running lower clamping jaws 25.
- Fig. 6 shows the pivoting of the jaws.
- the upper part of the drive device performs the same movements synchronously.
- the clamping jaws 19, 25 initially capture the individual lines 5 parallel to the weft insertion at the clamping point.
- a clamping jaw with the right start cam 22 Immediately after the clamping, a clamping jaw with the right start cam 22 'runs against the right start roller.
- the position of a jaw is shown hatched during pivoting and fully pivoted.
- clamping jaws which lie in the direction of travel of the chain are also deflected.
- additional thrust rollers ensure this. This ensures that the tension in the clamped material can be maintained longer than just directly at the clamping line.
- the clamping is released by the pressure tracks ending or being bent.
- the clamping jaws are brought back into their starting position by the spiral springs 20.
