Definitions

  • the present invention relates to a method for easily unwinding reels of wire rod, aluminum or copper or any other metal, whatever the original winding mode. It also relates to the apparatus making it possible to apply said method.
  • the wires concerned are mainly but not exclusively non-ferrous metals and mainly aluminum and copper. These metals are currently continuously cast and rolled at very high speed by the well-known continuous casting and rolling process on a wheel partially surrounded by a flat metal belt.
  • the length, the eccentricity of the turn, the speed of rotation of the tube forming the helix, the distribution, the average diameter, the thickness of the sheets obtained by continuous or sequential rotation more or less slow, from the pallet or the receiving mandrel, various forms of winding are obtained.
  • the more or less thick tablecloths can be arranged, laid flat in different ways, either in a spiral, in a tablecloth, in rosettes, etc. as shown in FIGS. 3, 4, 5 and 6.
  • Coils very bulky, having a fairly low weight / volume ratio (hence significant transport costs) are generally obtained from a normal coil (2) obtained by circular winding and cutting or from coils obtained by helical winding without mandrel. They are then r éenroulées rosette, the yarn is drawn in one and distributed over the second by means of a train of drive rollers and pressers analogous to that described in the patents already mentioned above.
  • the object of the present invention is, whatever the initial winding mode of the spool of thread, to be able, by means of a very simple apparatus, to unwind it without any incident by vertically pulling the thread starting from the center , using the patented machines already mentioned.
  • the inertia of the reel and its reel (reel) limits the speed and especially the variations in speed of the reel.
  • the invention also aims to avoid these drawbacks.
  • the main purpose of the device is to unwind thread.
  • the solid fixed vertical upright consists of two irons U whose free edges of the wings are welded.
  • the corset is locked and tightened by oscillating locks with a spiral profile cam or by fixed hooks at the end of springs or by jacks, in particular jacks tires.
  • a joining device between the plates one can ensure a permanent unwinding or unwinding of the wire, without any stopping. This is done by joining the end of the end of a reel with the end of the start of the next reel, it being understood that we always start by unwinding the central turns of the coils by winding up the outer turns.
  • the device which is the subject of the invention, which has just been described, makes it possible to increase the efficiency of machines for injecting aluminum wire or flat, which is the subject of the patents cited above. They make it possible to obtain a large supply of food, the supply of a current product being able to be obtained at the best price. Handling is also reduced and an original product can be used without intermediate modification. The mechanism requires no energy consumption. The workforce is reduced. Storage security in a space restricted in the workplace is reached.
  • the method and apparatus of the invention avoid, for instance, some drawbacks which have been mentioned at the beginning of the present specification and in particular the productive ti on nodes, blocking and metal loss that follows.
  • Devices with multiple plates also allow the storage of a large quantity of metal ensuring the supply of the devices of use by reducing the frequency of restocking.
  • the apparatus of the invention comprises a horizontal plate (9) on which is placed the pallet (7) which supports the coil (2) arranged with its vertical axis. It also consists of a solid main vertical upright (10) fixed firmly on the edge of the plate (9) on which pivot, thanks to hinges (11), the crosspieces (12) of a corset articulated in several leaves (13) to (20) which have vertical uprights (21), (22), (23), (24) as well as (25), (26), (27), (28) which project towards the interior to externally hold the coils such as (2).
  • the extreme leaves (17), (18), (19), (20) have locks (29), (30) oscillating, having a cam with a spiral profile, a device which is well known and which can also be replaced by any equivalent locking device such as a spring with a hook.
  • the oscillation of the leaves (13, 14) is ensured by pneumatic cylinders (58, 59) which open on the upright (10).
  • the leaves (13) to (16) have a partially cylindrical plane and make about a third of the turn of the coils (2).
  • the uprights (21) to (24) are designed to rest on the coils (2) and hold them. The coils (2) are thus held not only by the uprights (21) to (24) but also by the main upright (10).
  • the uprights (21) to (24) comprise, as we have seen, hinges for the leaves (17) to (20) which are also partially cylindrical and each form approximately one sixth of the turn of the coil.
  • an important characteristic of the apparatus of the invention resides in the horizontal pressure roller (43) disposed radially relative to the coil (2), the axis of said roller being rigidly fixed in a slide (44) (FIG. 11) capable of moving vertically in the upper part of the main upright (10) which is tubular, generally of square section and produced by two irons U whose edges are welded.
  • the movement of the rollers (43) (along the arrow (45)) is possible thanks to vertical slots (46) formed in the upper part of the upright (10). It is controlled by a pneumatic cylinder (47) placed inside the main part of said upright (10).
  • the vertical stroke of the roller (43) is of the order of ten centimeters.
  • This roller (43) is raised when the reel (2) is placed and it is then lowered when the reel (2) is in place.
  • the length of the roller (43) is slightly less than the radius of the coil (2).
  • the apparatus of the invention resides in the horizontal eyelet (48) which is fixed and disposed at least one meter above the center of the coil (2).
  • the eyelet (48) is connected to the upright (10) by a support (49).
  • a final important feature of the device lies in the return drum (50), with a horizontal axis, which is located a few meters above the eyelet (48).
  • This drum generally comprises lateral flanges (51), (52) for guiding the wires (53) to (56).
  • FIGs 12 and 13 there is shown a double device capable of supporting two coils (2) which are arranged on either side of a single main upright (10).
  • return drums (501) and (502) are provided for the wires (53) and (54).
  • wire (53) For the wire (53), a path has been shown in solid lines which directs it in the opposite direction to the wire (54).
  • a path has also been shown in dotted lines (531) which directs it in the same direction as the wire (54).
  • FIG 14 there is provided an arrangement of two devices such as those shown in Figures 12 and 13 and which are arranged side by side so that the coils (2) are placed in a square.
  • return drums (503), (504) which direct the wires (53) and (54) on the one hand and (55) and (56) on the other hand in two different directions.
  • the amount (10) is generally welded to the horizontal plate (9) which is then sealed by any means at a location chosen as being the most suitable to supply the most simply, economically, correctly, the machine for injecting or drawing the metal (copper, aluminum, steel, etc.).
  • This location is always at a level lower than that of the machines to be fed, the proper functioning of the system being all the better the greater the level difference, that is to say the distance between the eyelet (48 ) and the return drum (50) will be important.
  • the horizontal pressure rollers (43) rotate on ball bearings and have a length slightly less (from 100 to 150 mm) than the outside radius of the spool (2) to be unwound from the center. As this radius can vary, the length of the roller (43) is adjusted, by sliding it axially in its support and locking it in the desired position.
  • the apparatus shown in Figures 18, 19 which comprises at least two plates side by side to support the coils (2a and 2b). Each of these plates corresponds to an upright (10) and a horizontal pressure roller (43). On the other hand, there is only one oblong eyelet (481) supported at a sufficient height by the bracket (60) and the support (491). A guide 61 is also provided in the form of a funnel before the drum (506).
  • a planer (64) is provided which performs electrical resistance welding. or sparkling.
  • the oblong eyelet (481) can advantageously be produced by two parallel rollers.
  • a coil (2) of two tonnes of wire for example, with the simplest winding, therefore the cheapest, is placed on each side of the uprights (10) constituted by welding two U irons. So there are four tonnes of wire.
  • each coil (2) At the upper part of each coil (2), the radial roller (43), pushed vertically by the jack (47), is applied to the upper face of the coil (2) and holds all the turns firmly when a upward tensile force is exerted on the wire (53) or the profile. Each turn (57) is then forced to pass one by one under the roller (43) by approaching the center before engaging in the direction eyelet (48).
  • This operation has the effect of clearing any trapped turns.
  • the main tensile force acting on the roller (43) makes it possible to reduce that acting on the coil by reducing the angle of attack of the wire on the internal wall of the cut turns.
  • the radial holding roller (43) combined with the uprights (21), (22), (23), (24) and (10) distributed every 120 ° around the coil (2), this can be done until the end without the slightest incident.
  • the eyelet (48) placed at the top of the uprights (10) makes it possible to obtain a correct unwinding of each reel (2) located on each side of said amount (10) and whatever its initial winding (right or left).
  • Another coil can then be brought to the location where the coil was (2b).
  • the inner strand of this new coil is then pulled to the planer (64) to weld it to the outer strand of the coil (2a). We always manage to pass these strands above the leaves (14).
  • This method and these devices can be applied to unwind cored wire, that is to say a wire inside which has been incorporated a powder (silico-calcium or powdered magnesium, in particular) coated in a strip, for example made of steel or aluminum shaped as a relatively flexible continuous tube inside which the powder (fodder) has been incorporated before the tube is closed.
  • a powder silicon-calcium or powdered magnesium, in particular
  • a strip for example made of steel or aluminum shaped as a relatively flexible continuous tube inside which the powder (fodder) has been incorporated before the tube is closed.
