Definitions

  • the present invention is related to a thread feeding buffer for feeding a fibre thread from a magazine roll to a feed apparatus at a robot arm which is freely movable in the room, and of the type, which is described in US patent application No 08/693,155.
  • fibre reinforced thermosetting plastic products can be automatized by the use of an industrial robot, by means of which a fibre feed apparatus can be controlled, so that precise amounts of fibers are fed out which are oriented for maximum strength, without the fibers projecting out through the outer plastic layer of the product. Owing to the repeatability of the robot, the quality of these products can be increased considerably, simultaneously as problems related to bad work environment and labor fatigue can be solved.
  • the fibre feeding apparatus is preferably located in a feedout head which can be mounted upon a movable robot arm.
  • One or more fibre threads are supplied to the feedout head, which cuts the threads in suitable lengths.
  • the feeding speed of the fibre thread can be in the range of about 10 meters per second. At such a feeding speed, it is difficult to stop the feeding of thread without any risk of getting the thread tangled.
  • the object of the invention is therefore to provide an arrangement at a thread feeding buffer which solves the above described problem.
  • the entangling protection arrangement for a thread feeding buffer for a fibre thread fed from a supply and along a path comprising a first guide for the thread, for receiving the thread from the supply, a contactable brake surface over which the thread is fed from the first guide; a brake element movement into control with the brake surface for braking movement of the thread past the brake surface; a movable thread guide in the path of the thread past the brake surface, a support comprising two substantially vertically arranged guide rods supporting the movable thread guide for movement; a further guide following the movable thread guide in the path of the thread and past which the thread is draw; the support enabling the movable thread guide to be moved by the thread to reduce the length of the thread path between the brake element engaging the brake surface and also permitting the movable thread guide to move to lengthen the distance between the brake surface and the further thread guide to absorb slack in the thread on the path between the brake surface and the further thread guide, is characterized in that at least one of said guide rods is provided with means arranged to
  • FIG. 1 is a plane view of a thread feeding buffer according to the invention, with the movable thread guide moving upwards, and
  • Fig. 2 a corresponding view showing the movable thread guide according to Fig. 1 moving downwards.
  • the thread feeding buffer comprises a stand 10 with two vertical guide rods 11.
  • the stand 10 carries an elbow arm 12 with a thread eyelet 13 for a thread 15 which is wound off from a roll 14.
  • the thread can consist of a multiple fibre thread of glass, carbon fibre or synthetic fibre.
  • the thread eyelet 13 provides for a substantially friction free passage of the thread.
  • the thread runs upwards from the roll 14 which is located at ground level, through the thread eyelet 13 and further over a bar 16 which changes the direction of pull back vertically down between the guide rods 11.
  • a thread guide 17 is movably guided by the guide rods and is provided with further thread eyelets 13, through which the thread 15 runs. Then the thread runs on from the thread guide 17 in the direction upwards to a thread guide channel 18, which guides the thread further to a not shown robot arm.
  • a thread brake cooperates with the bar 16 and is composed of a clamp plate 19, which is mounted at the outer end of a pneumatic cylinder 20 which is connected to the stand 10.
  • the clamp plate can be brought in or out of engagement with the bar 16 by operation of the cylinder 20, whereby the feeding of the thread will be stopped.
  • the thread feeding buffer operates in the following way: During normal thread feeding, the pulling of the thread, via the thread eyelets 13 and the bar 16, creates an even resistance in the thread which results in an advantageous even outfeed. If the robot arm is moving in the room, so that more or less thread has to be fed out momentarily, the thread guide 17 will be able to move up and down respectively along the guide rods, wherein the thread will receive a rapid compensation in length.
  • a first one of the vertical guide rods 11 of the stand 10 at its lower end is movable by being supported in a direction to and from the opposite vertical guide rod by means of a ball 21 or the like being movable in a transverse groove 22.
  • the lower end of the said first vertical guide rod 11 is in its neutral position, as shown in Fig. 1, where the yoke provided with the movable thread guide 17 is moving upwards .
  • the movement of the yoke is preferably monitored by a sensor 24 thus that a rapid downward movement of the yoke makes the sensor emit a signal for activating the force piston 23.
  • This sensor is preferably connected to a central unit 25 receiving a signal from the sensor 24, representing the current speed of the yoke, whereby the signal is compared to a threshold value in said central unit, whereby the central unit is arranged to emit an output activating the force piston 23 when the sensed downward speed of the yoke exceeds said threshold value.
  • the guide rods can be exchanged for other means for controlling a buffer of fibre thread.
  • a spring means can replace the action of gravity upon the thread guide means 17.

Abstract

L'invention concerne un tampon d'alimentation de fil servant à alimenter un fil (15) de fibre d'un rouleau (14) de magasin à un appareil d'alimentation situé sur un bras de robot pouvant être déplacé librement dans une pièce. Le tampon d'alimentation de fil comporte un moyen (16, 19, 20) de freinage de fil et au moins un guide-fil (17) mobile sur lequel agit une poussée. Le fil provient du rouleau (14) de magasin, passe par le moyen (16, 19, 20) de freinage, à travers le guide-fil (17), et continue en direction de l'appareil d'alimentation de telle sorte que la poussée permet de produire un tampon de fil entre le moyen de freinage et l'appareil d'alimentation, ce tampon étant de longueur variable. Au moins une tige de guidage servant à guider le guide-fil mobile est équipée d'un dispositif conçu pour produire un effet de freinage sur le mouvement descendant du guide-fil mobile, afin de prévenir un embrouillement du fil passant à travers le guide-fil mobile, consécutif à une chute rapide dudit guide-fil mobile.
