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 of varying width and thickness.
- the flat elements produced by the production lines must be rolled up so that they can be easily transported to the subsequent processing stages.
- the rewinders used on the continuous production lines be equipped with devices allowing, without interrupting production, the passage from a full reel, when it has reached the expected diameter, to a new empty reel . It is obvious that such an operation which must be carried out continuously, requires that at a given moment, the sheet is cut at the production speed of the line, and driven by suitable devices on the mandrel of the new reel to re-supply. These are the devices which are called sheet cutting systems for automatic reel change on reel.
- the winders allowing this type of application all have a certain number of common elements which are as follows:
- reel pins (1) are each provided with their drive device, 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 moment the sheet (F) arriving continuously from the production line, the drive system and its regulation delivering on the spindle the torque necessary for the sheet is driven at the desired speed and at the desired tension.
- the devices necessary for torque control are either dancer rollers or electronic tension gauge systems located upstream of the spindle (1) and responsible for continuously measuring 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 torque necessary for the 'winding.
- the empty spindle which has been brought in the meantime by its own regulation system at the desired speed, comes into contact with the sheet (F) to be wound, the full reel then being in the so-called unloading position, but continuing to drive the product, as shown in Figure 1.
- FIG. 2 represents a variant of the machine of FIG. 1.
- Such machines are used when winding large plastic sheets (up to 8 and 9 meters wide), for thin films of thickness between 5 and 100 microns, but generally between 10 and 30, and at speeds of several hundred meters per minute.
- At least two cylinders including a first cylinder (6), called tension measurement, is equipped an electronic gauge for continuous measurement of the sheet tension (F), or preceded by a dancer roller fulfilling the same function.
- This cylinder (6) must be positioned in such a way that the sheet approaches the cylinder in a horizontal position (either from above or from below) so that, during the movement of the carriage following the increase in the diameter of the coil, the angle of locking of the sheet around the cylinder is not modified so that the reading of the tension is not disturbed by the modification of locking.
- a second cylinder, called contact cylinder (4) is also necessary to guide the sheet to the winding point.
- Two types of winding are frequently used, the so-called contact winding, as shown in FIG. 3, during which the contact cylinder exerts a light pressure on the coil being wound up, so as to evacuate the air. which would otherwise risk being trapped in large quantities in the coil due to the speed of winding 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 kept roughly constant from the winding point.
- the sheet preferably fed horizontally, can pass either above or below the set of cylinders mounted on the carriage. This choice has very important consequences for the nature of the cutting system.
- Figure 5 shows a reel equipped with a cutting device.
- This cutting device must be implemented automatically at the time when cutting is desired, cutting must be carried out in such a way that it disrupts the progress of the sheet as little as possible, the cutting point having to be chosen so that the sheet, immediately after cutting, or in the case of a progressive cutting, the point corresponding to the start of cutting, can easily be wound around the spindle (1) to be re-fed so as to ensure the start of the coil.
- 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 (1 1) generating electrostatic charges on the surface of the sheet ensuring contact of the cut sheet with the metal pin to be re-supplied.
- electrostatic systems (1 1) generating electrostatic charges on the surface of the sheet ensuring contact of the cut sheet with the metal pin to be re-supplied.
- adhesive tapes or possibly jets of vaporized liquid are used to ensure reliable contact.
- the multiplicity of functions to be fulfilled by the cutting device means that it is generally complex, cumbersome and that its operation is ensured only on condition that the arrangement in space of all the elements which constitute the spindle to be re -filling the sheet and the cutting system itself are very well defined.
- the object of the invention is to provide a winding machine having a device making it possible to avoid production losses by allowing the automatic cutting of a sheet at the end of winding a reel and with a view to its winding on an empty spindle intended to support another reel, and also allowing a start of winding not on an empty spindle, as is the case with existing devices, but on a reel already started, regardless of the diameter of the coil considered.
- the machine to which it relates of the type comprising a frame on which is mounted a barrel equipped with at least two parallel spindles and each associated with rotation drive means known per se, the rotation of the barrel allowing simultaneously the evacuation of a full reel and the supply to the winding station of an empty spindle, and a carriage movable perpendicular to the axis of the spindles and itself carrying the supply rolls of the sheet machine to be rolled up, is characterized in that the carriage comprises:
- a cutting device arranged between the two cylinders respectively for measuring voltage and contact, upstream of the winding point on the spindle or the coil to be formed.
- the cutting device being located between the tension measuring cylinder and the contact cylinder, i.e. before the winding point on the spindle or on the coil to be re-supplied, the position of the sheet to be cut is perfectly defined, regardless of the diameter of the spindle or of the spool on which the sheet must be re-fed.
- the tension and contact measuring cylinders are motorized.
- the sheet is therefore perfectly controlled in tension due to 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 control means which cause, before cutting, an increase in the tension of the sheet in the area between the tension measuring cylinder and the winding point by acting on the drive speed. of the spindle and / or of the tension measuring cylinder, and an increase in the pressure of application of the contact cylinder on the spindle or the coil.
- the conditions for cutting and winding on the new support are perfectly fulfilled thanks to the increase in the tension of the sheet and the increase in the pressure of application of the contact cylinder against the spindle or the reel feed.
- the sheet thus appears perfectly flat with a slight overpressure conducive to good penetration of the knives and to a clean and rapid cutting.
- the cut point driven by the natural speed of the sheet, penetrates very quickly between the two cylinders.
- a deionization device is provided, which is activated just before cutting, to remove electrical charges from the surface of the contact cylinder.
- the cutting device comprises, 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 part and the winding spindle.
- Figures 1 and 2 are two very schematic views of a winder
- Figures 3 and 4 are two views illustrating two possibilities of feeding the spindle on which the winding must be performed;
- Figure 5 is a view of a reel equipped with a known cutting device
- Figure 6 is a view of a winder equipped with the cutting device according to the invention
- Figure 7 is a partial perspective view of the part of the machine comprising the cutting device.
- FIG. 6 represents a rewinder 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 the sheet F arrives substantially horizontally.
- the carriage 5 also carries a horizontal cylinder 14, which is a contact cylinder with the coil B formed on the spindle 1 or with the spindle 1, before formation of the coil.
- the cylinder 14 is parallel to the cylinder 16, disposed below the latter, and substantially vertical to this cylinder.
- a cutting device 11 comprises a rail on which movable knives 12 are mounted intended to cut the sheet.
- an ionization bar 1 5 which is intended to be activated just before cutting to electrostatically charge the sheet F and create an attraction between the cut part thereof and the pin winding 1 or coil B as appropriate.
- a deionization bar 13 which is activated just before cutting, to remove the electric charges from the surface of the contact cylinder.
- the cutting is carried out on a taut surface, allowing a frank cutting, the cut end tending, taking into account the speed of the sheet, the proximity of the cylinder 14 and the spindle 1, and the respective electrical charges. of the cylinder 14 and of the sheet, to be wound on the spindle or on the reel, insofar as it is a question of re-supplying a reel already started.
- the invention brings a great improvement to the existing technique by providing a machine for winding a continuous element to form coils, allowing the cutting without winding of the winding, and also allowing start winding, not only on an empty spindle, but also on a spool on which winding has already started.
