Definitions

  • the present invention relates to an automatic reel of an elongated product intended to form torches, comprising two permutable winding drums and cutting and fixing means capable of cutting the elongated product during each permutation and of fixing the free end of this product to a drum at each cutting operation.
  • Automatic winders are used to wind various elongated products which open continuously from a production line. It can be electrical cables, but also plastic profiles or tubes having a circular profile or another shape.
  • the reels generally have two drums designed either to receive coils or to directly support the winding when it comes to forming torches. By working alternately on one drum and on the other, it is possible to interpose certain operations on the winding which is finished, while continuing the winding of the product on the other drum.
  • various means are already known which make it possible to automatically pass the elongated product from one drum to another when a coil or a torch is finished.
  • Patent GB-A-1074 709, American patent US 3,704,839, German patent DE 821,666 or Swiss patent CH 582106 for example describe devices of this kind.
  • the object of the present invention is to provide a solution to this problem by means of a device which does not require any adjustment whatever the section of the product which it is desired to wind.
  • each drum carries a cutting and pinching device actuated by a control member.
  • the reel shown schematically in Figs. 1 to 2 is arranged so as to form, from a plastic tube 1 which leaves a production line, torches which can be harvested alternately on each of the two drums 2 and 3 which the reel comprises.
  • These two drums pivot at the two ends of an arm 4 which constitutes the frame of the barrel and which is itself supported in the middle of its length by a shaft end 5 in a fixed frame 6 containing the bearing of the shaft 5, means for driving the barrel 4 in rotation and various accessories which are not important here.
  • the operation of the reel is as follows: the free end of the product 1 is fixed to the reel drum which is in position 3 and while this drum is rotated, the product 1 is guided by a slicing device 7 so as to form layers of successive turns on the drum 3.
  • the barrel 4 rotates clockwise in FIG. 1 by 180 ° and the drum 2 which is empty takes the place of the drum 3.
  • the product 1 is sectioned on the empty drum and fixed to this drum by a clamping device while a binding machine 8 disposed in the vicinity of the drum which is in position 2 comes into action to bind the torch formed on this drum, which allows the unloading of the torch.
  • the drum in position 3 continues to rotate, so that a new torch is formed on its barrel.
  • each drum has two flanges 9 and 10 and between these flanges a barrel 11, but as will be seen later, the flanges and the barrel of each drum are divided into segments or sectors distributed circumferentially around the axis of the drum, and the sectors which constitute the flange 10 are pivotably mounted so as to assume a position oriented parallel to the axis of the drum as shown in 10 ⁇ in FIG. 2.
  • the torch formed on the barrel 11 is accessible and can be easily discharged.
  • Figs. 3, 4 and 5 we will describe in more detail the constitution of one of the drums 2 and 3, and more precisely of the cutting and pinching device that each of these drums comprises.
  • Fig. 3 is a partial elevation view in the direction of the arrow A in FIG. 1 showing part of a drum whose axis (not shown) is located at the top of the drawing with a horizontal orientation.
  • a star 12 which is integral with the shaft connecting the drum to the barrel 4.
  • This star has a certain number of radial grooves converging towards the axis of rotation of the drum and which each serve to fix and guide a base 13 whose position can therefore be adjusted in the radial direction which allows to vary the diameter of the drum barrel and therefore to adapt it to torches of different dimensions.
  • the number of plinths and therefore grooves formed in the star 12 can be for example six or eight, or if necessary four, depending on the embodiments.
  • Each base 13 comprises means for guiding and clamping a flange sector 14 which is contained in a plane perpendicular to the axis of the drum and which is supported by a slide 15, so that each of the flange sectors 14 can be moved in the direction parallel to the axis of the drum, which makes it possible to fix its position and consequently to determine the width of the torch which will be formed on the drum.
  • the base 13 has an axial extension 13a at the free end of which pivots a profiled arm 16 to which is fixed a foldable flange sector 17.
  • This flange sector has the same shape and the same dimensions as the sector 14
  • the arm 16 and the sector 17 together constitute a valve which can be folded down around a pivot axis 18 which extends in the circumferential direction at a distance from the axis of the drum which is determined by the position of the base 13.
  • the base 13 also carries a barrel plate 19 which is constituted by a curved sheet. This sheet is fixed at one end to an arm 20 which pivots at 21 on the base 13.
  • the arm 20 is linked by an articulated link 23 to a transmission and control mechanism.
  • This transmission and control mechanism firstly comprises a jack, the cylinder 24 of which is fixed by its base to the base 13 in a position parallel to the axis of the drum.
  • a movable rod 25 comes out of the cylinder 24 and at its free end it is articulated on a transmission lever 26 which pivots itself at 27 on the end of the axial extension 13a of the base 13.
  • the lever 26 has as a triangular shape . In the vicinity of one of its peaks it is linked by the articulation 28 to the rod 25 of the jack, while in the vicinity of another vertex, opposite the articulation point 27 it is articulated by means of a link 29 on the arm 16 carrying the sector 17. It will be understood that an actuation of the jack 24 causing the rod 25 to move to the left in FIG.
  • This knife blade 30 is a steel blade fixed in a radial plane containing the axis of the drum at the end of the extension of the base 13.
  • This knife blade 30 has a profiled edge 31 arranged so as to facilitate cutting of the product 1.
  • this knife is arranged in a radial position between the barrel 11 and the pivot axis of the valves. 17.
  • the extension 13a carries a pinch lever 32 (fig. 4) which pivots around a hinge 33 on the extension 13a.
  • this lever has a segment in the shape of a claw 34 which is kept pressed against the end of the product 1, housed under the barrel segment 19.
  • the elements of the drum are recognized in FIG.
  • the arm 16 of the valve 17 has between its articulation point 18 and the place where it is fixed to the sector 17 a notch 35 which constitutes a hooking member for the product 1.
  • the pinch lever 32 is biased by an arguated hairpin spring 36 which is fixed by a stirrup 37 on the upper part of the base 13 and which itself carries at the end of one of its branches a stirrup 38 embracing the lever 32.
  • the end of the other branch of the spring 36 is also engaged in a cylindrical opening which has a stud 39 pivotally mounted on the extension 13a of the base 13.
  • the drum which is in position 2 remains stationary during the formation of a new torch on the drum which is in position 3, that is to say that the valves 17 remain in the open position and the clamping lever 32 remains in the raised position as seen in FIG. 5.
  • the product is instantly sectioned and at the same time, as the roller 37 performs a downward movement in FIG. 5, it lets the pinch lever 32 move downward under the effect of the force of the spring 36 transmitted by the caliper 38.
  • the initial segment of the new torch is therefore pinched against the internal face of the barrel segment 19 , so that the product 1 continues to be driven, but by the empty drum, and no longer by the full drum.
  • the valve 17 can continue its stroke until the final position of its movement as shown in FIGS. 3 and 4.
  • the product segment which is adjacent to part 42 passes between the barrel segment equipped with the cutting and nipping device and the segment next and go over part 19 of that segment.
  • the pulling force which is exerted on the product 1 is transmitted to this product by the pinching lever 32 and to ensure the achievement of this effort, a bracket 43 is also provided on the extension 13a of the base 13 to hold the lever 32 in position.
  • the device thus produced is capable of operating in a perfectly regular manner. It requires no adjustment whatever the section of the elongated product that one wishes to wind. The force required for gripping is given by the hairpin spring 36 and therefore the gripping force is greater the greater the section of the product.
  • the operation of the device shown in the drawing has been explained by assuming that the elongated product 1 was a plastic tube, but it should be understood that this product could also be a cable, a flexible profile, a bar, or any other elongated product. capable of being packaged as a torch or coil.
