Definitions

  • the present invention relates to a device for forming an accumulation or reserve loop intended to equip a strip material processing line.
  • the line input and line output sections are separated from the central section, where processing is carried out, by tape accumulators.
  • These accumulators are intended to store the strip so as to allow the section where the processing takes place to operate at a constant speed of travel of the strip; this, even when the »input « and »output « sections interrupt their operation for changing the coils.
  • this accumulator comprises a looping carriage, separator assemblies intended for the support of the upper return portion of the strip and a series of pairs of fixed frames arranged on either side of the carriage at selected locations in the frame and intended for supporting said separator assemblies.
  • the present invention aims to remedy the aforementioned drawbacks.
  • the accumulator device according to the invention makes it possible to place the separator rollers in well-determined positions, thus avoiding the drawback due to the rollers mounted on a carriage, and to place each of said rollers on a beam resting on two supports, thus avoiding disadvantage due to the separating arms mounted in a cantilever pivoting about a vertical axis. It is characterized in that it is equipped with means for storing the separator assemblies on the looping carriage, as well as means for successively placing said separator assemblies on the frame at selected locations thereof.
  • the reference 1 designates the wrap-around carriage of the tape accumulator, which moves, in a conventional manner, on rails 2 by means of wheels 3, being pulled to the right in the direction of widening of the loop 4 using a cable 5 fixed to it, or to the left in the direction of shortening thereof by the traction exerted on the strip.
  • the strip 4, the lower part of which is supported by lower support rollers 6, passes under the carriage 1, then around the deflector drum 7 fixed on the carriage 1, and then returns back, the portion of return, or upper portion to be supported, in a very conventional manner, by sets of separator rollers 8, of suitable spacing from one set to another, located above the lower support rollers 6.
  • each separator assembly 8 constituted in a manner known per se of two rollers (9, 10) mounted on a beam 11, is stored, when not in use, on the looping carriage 1, which is therefore provided with notches 12 for this purpose.
  • the frame is provided, at the locations corresponding to the desired positions for each separator assembly put in place, with pairs of fixed frames, a frame on either side of the passage of the carriage, such as frame 13, each provided with a device articulated 14 allowing the unloading and loading of each separator assembly on the looping carriage 1, as well as their maintenance in the high working position.
  • Each of the articulated devices 14 is constituted, as shown in the drawings, by a set of connecting rods 15 hinged together on which is mounted a notch piece 16 making it possible to take, hold in the high working position, then redeposit the assembly separator corresponding to it on the cart.
  • each articulated device 14 varies according to the location where they are located along the rails 2, being adjusted for each of them so that each piece 16 comes to grip the appropriate separator assembly 8 in its storage position provided on the carriage: between two successive devices 14, the difference in length of the horizontal connecting rod 19 is such that each part 16 comes to grip separator assemblies 8 separated from the distance separating two notches 12.
  • Each separator assembly 8 or each part 16, once in the high working position as shown diagrammatically in FIG. 4, is advantageously locked in this position by an additional device, which has not been shown in FIGS. 1 to 4 so as not to do not overload the drawings, which guarantees good stability of the separating rollers, even in the event of tape breakdowns.
  • the additional blocking device used in the example considered will be described with reference to FIG. 5.
  • Figure 5 shows the part 16 in the lifting position of the separator assembly 8, in a phase lying between the phase of Figure 3 and that of Figure 4.
  • a blocking device 20 in the high position of the articulated system 14 essentially comprising a pneumatic cylinder 21, fixed in horizontal and transverse position so that its rod 22, once extended, can engage in a cavity 23, of corresponding shape, drilled in the bar 24 constituting the bearing end of the beam 11.
  • an oleopneumatic damper 25 making it possible to absorb the shock due to the vertical forces which can occur during the removal of the separator assemblies 8.
  • the devices allowing the installation and the removal of the separator assemblies are mounted on the frame. It goes without saying that we could also, without departing from the scope of the invention, mount such a device, unique, on the carriage itself.
