Definitions
- the present invention relates to a winding machine, or winder, of a continuous flat element to form coils.
- Winders are used in a very large number of branches of industry where the machines and processes used result in the continuous production of a flat element more or less large width and variable thickness.
- the flat elements produced by the production lines must be wound up so that they can be easily transported to further processing steps.
- Winders for this type of application have all a number of common elements which are:
- rewinder pins (1) are each provided with their device drive, and are mounted integrally on a rotary assembly called barrel (2) mounted on a frame (3).
- Each spindle (1) with its associated drive device receives at a given time the sheet (F) arriving continuously from the line of production, the drive system and its regulation delivering on the spindle the torque necessary for the sheet to be driven at speed desired and under the desired tension.
- the devices necessary for torque regulation are either dancer rollers or electronic voltage gauge located upstream of the spindle (1) and loaded continuously measure the tension of the sheet (F) so as to control the motor according to a winding law established in advance.
- the spindle itself is not driven, but it is a contact roller (4), itself driven, which delivers the necessary torque to the winding.
- this device is made up depends a lot on the how the elements that precede the whole are made up barrel / pin and whose function is to feed the product to be wound up convenient way while allowing regulation of the devices drive.
- These training devices generally consist of one or more cylinders each fulfilling well-defined functions and which are generally integral with a mobile carriage (5) allowing the cylinders indicated above to maintain a geometric arrangement constant as the diameter of the coil increases as winding measurement.
- FIG. 2 represents a variant of the machine of FIG. 1.
- Such machines are used when winding wide plastic sheets (up to 8 and 9 meters wide), for thin films with a thickness between 5 and 100 microns, but generally between 10 and 30, and at speeds of several hundreds of meters per minute.
- a second cylinder called contact cylinder (4)
- contact winding Two types windings are frequently used, the so-called contact winding, as shown in Figure 3, during which the contact cylinder exerts a light pressure on the reel in the process of winding, so that evacuate the air which would otherwise risk being trapped in large quantities in the reel due to the winding speed of the sheet, and the so-called "gap" winding, as shown in FIG. 4, in which the contact cylinder (4) is at a short distance and is maintained at near constant to the winding point.
- This type of winding is preferred when the speed is low because the risk of air entrapment is then low, or when the thickness of the product to be wound up is not very regular and contact type operation would be likely damage the rolled up product.
- the horizontally fed sheet may pass either above or below the set of mounted cylinders on the cart. This choice has very important consequences for the nature of the cutting system.
- Figure 5 shows a reel equipped with a cutting.
- This cutting device must be implemented automatically when the cut is desired, the cut in front be insured in such a way that it disturbs the least possible unwinding of the sheet, the cutting point to be chosen in such a way so that the sheet, immediately after cutting, or in the case a progressive cut, the point corresponding to the beginning of the cut out, can easily be wrapped around the spindle (1) to be re-supplied so as to ensure the starting of the coil.
- the cutting device provides for tying rollers (9) bringing the sheet (F) close to the spindle (1) to feed.
- the device must provide, in addition to the cutting system by fixed blade (10) or by movable knives, means for guiding the sheet against the new spindle and which are either air jets or brush systems, or so-called electrostatic systems (11) generating the surface of the sheet of electrostatic charges ensuring the contact of the sheet cut with the metal pin to be re-fed.
- means for guiding the sheet against the new spindle which are either air jets or brush systems, or so-called electrostatic systems (11) generating the surface of the sheet of electrostatic charges ensuring the contact of the sheet cut with the metal pin to be re-fed.
- adhesive tapes or possibly jets of vaporized liquid are used to ensure reliable contact.
- the multiplicity of functions to be fulfilled by the cutting makes it generally complex, heavy and its functioning is ensured only on condition that the arrangement in the space of all the elements that make up the spindle to re-supply the sheet and the cutting system itself are fine defined.
- This aspect can be further increased if, what happens unfortunately sometimes a second break occurs again before the new coil has reached a diameter economically valid. In this case, it is the entire production corresponding to two coils started, but insufficiently completed, which is lost.
- the object of the invention is to provide a winding machine having a device to avoid production losses by allowing automatic cutting of a sheet at the end of winding of a coil and for its winding on an empty spindle intended for support another coil, and also allowing a start not on an empty spindle, as is the case with existing devices, but on a coil already started, whatever the diameter of the coil considered.
- the cutting device being located between the measuring cylinder of tension and the contact cylinder, i.e. before the point winding on the spindle or on the coil to be re-supplied, the position of the cutting sheet is perfectly defined, whatever the diameter of the spindle or spool on which the sheet is to be fed.
- the cylinders of voltage and contact measurement are motorized.
- the sheet is therefore perfectly controlled in tension of the made of the proximity of the tension cylinder, and is well pressed against the spindle or the coil to be re-supplied by the contact cylinder.
- the machine is equipped with means for commands which cause, before cutting, an increase in the sheet tension in the area between the measuring cylinder tension and the winding point by acting on the drive speed of the tension measuring spindle and / or cylinder, and an increase the contact cylinder application pressure on the spindle or coil.
- the cutting and winding conditions on the new support are perfectly filled thanks to the increased tension of the sheet and increasing the application pressure of the cylinder contact against the spindle or the coil to be re-supplied.
- the leaf presents itself thus perfectly flat with a slight overpressure conducive to good penetration of knives and a clean and quick cut.
- the point cut driven by the leaf's own speed, penetrates very quickly between the two cylinders.
- a deionization device which is activated just before cutting, to remove electrical charges from the surface of the contact cylinder.
- the cutting device has, near the knife guide, an ionization bar extending transversely to the sheet, activated just before cutting to electrostatically charge the sheet and create an attraction between the cut out part and the winding spindle.
- Figure 6 shows a reel of the same type as those described above, and in which the same elements are designated by the same references as above.
- the carriage 5 is equipped with a horizontal cylinder 16 for measuring tension, on which sheet F arrives substantially horizontal.
- the carriage 5 also carries a cylinder horizontal 14, which is a contact cylinder with the coil B formed on pin 1 or with pin 1, before forming the coil.
- the cylinder 14 is parallel to the cylinder 16, arranged below the latter, and substantially vertical to this cylinder.
- a cutting device 11 This cutting device comprises a rail on which are movable mounted knives 12 for cutting the sheet.
- an ionization bar 15 is intended to be activated just before cutting to load electrostatically sheet F and create an attraction between the part cut from it and the winding pin 1 or the coil B according to the case.
- a deionization bar 13 which is activated just before cutting, to remove electrical charges from the surface of the contact cylinder.
- the cutting is carried out on a taut surface, allowing a clean cut, the end cut tending, taking into account the speed of the sheet, the proximity to cylinder 14 and pin 1, and electrical charges cylinder 14 and sheet, to be wound on the spindle or on the coil, insofar as it involves re-supplying a coil already started.
- the invention provides a great improvement to the existing technique by providing a machine winding of a continuous element to constitute coils, allowing continuous cutting of the winding, and allowing also to make a start of winding, not only on a empty spindle, but also on a spool on which the winding has already started.
