Definitions
- the present invention relates to a winding machine, or "winder”, of continuous product in sheet form, for forming coils.
- Winders are used in many branches of industry where the machines and production processes used result in the continuous production of a flat product of varying width and thickness.
- the flat elements produced by the production lines must be rolled up so that they can be easily stored and / or transported to the subsequent processing stages. This is the case in particular in industrial processes and machines allow the continuous production of fabrics, papers, plates, sheets and plastic films, nonwovens, etc ... For reasons of simplicity, this is the term " leaf "which is used below to denote various types of flat products.
- rewinders are used systematically at the end of the plastic film production lines in materials as diverse as polypropylene, polyester, polyvinyl chloride, polyethylene, complex coextruded sheets, etc. .
- the rewinders used on continuous production lines are equipped with devices allowing, without interrupting production, the passage from a full reel, when it has reached the planned diameter, to a new reel still empty.
- Winders intended for this type of application comprise, in a generally known manner, a machine frame on which is rotatably mounted, about a horizontal axis, a rotary assembly called barrel equipped with at least two parallel winding pins, a typical embodiment comprising two diametrically opposite pins, the pins being associated with means for driving in rotation.
- Each spindle receives, at a given moment, the sheet product arriving continuously from the production line, the drive means supplying the spindle with the torque necessary for the sheet product to be wound in a reel.
- the barrel rotates half a turn, simultaneously allowing the evacuation of the full reel and bringing, in the winding position, a new empty spindle.
- a cutting device intervenes before one exchange of the two pins, to cut the sheet material.
- the main part of the reel comprising the frame and the barrel carrying the pins, are necessarily associated with means for supplying the sheet product, the function of which is to supply the reel with product to be wound, this so suitable by ensuring the regulation of various operating parameters.
- These supply means comprise several cylinders and rollers on which the sheet product to be wound passes, and comprising in particular:
- a tension measurement cylinder on which the sheet product arrives substantially horizontally
- a second cylinder on which guides the sheet product to the winding point
- these cylinders and other rollers are carried by a carriage, on which are still mounted the means for measuring the tension and the other regulating members, as well as the cutting device.
- the carriage is mounted movable in translation horizontally, in a direction perpendicular to the axes of the barrel and of the reel pins.
- the frame of the reel being fixed, it is the carriage which moves as the winding of a coil, to ensure a permanent application of the contact cylinder on the coil, whose diameter is gradually increasing .
- the horizontally movable carriage comprises a large number of cylinders, rollers and other devices, such as the cutting device, which make this carriage a complex and heavy unit.
- the winder itself with its frame, barrel and two pins, as well as its ancillary devices, is a heavy and bulky machine.
- the size of the spindles cannot be reduced, in particular on machines of great width, since such a reduction would cause an unacceptable deflection of the spindles and, if the winding diameter is large what is generally desired, the frame is necessarily large dimensions.
- the present invention aims to avoid these difficulties, and it therefore aims to provide a winder of the kind considered, in which the sheet insertion operations can be performed at high speed, without the safety of the people in charge of these operations are threatened, even with a single operator.
- the subject of the invention is a machine for winding a continuous product in the form of a sheet, for forming coils, comprising a machine frame on which is rotatably mounted, around a horizontal axis, a barrel equipped with '' at least two parallel winding spindles, associated with rotary drive means, the rotation of the barrel simultaneously allowing the evacuation of a full reel and bringing it into position winding, an empty spindle, the machine further comprising means for feeding the sheet product to be wound, these means comprising various cylinders and rollers such as a tension measuring cylinder and a contact cylinder, as well as , preferably, regulating members and a cutting device, this winding machine being characterized in that the assembly comprising the frame, the barrel and the winding pins is mounted movable in translation horizontally, in a perpendicular direction to the axes of the barrel and of the pins, while the means for feeding the sheet product are fixed, the displacement in translation of the movable assembly comprising the frame, the barrel and
- the present invention proposes to maintain the means for bringing it to a fixed position, and thus the assembly consisting of the frame, the barrel and the pins which is mobile and which, more precisely, moves in the direction of travel of the sheet product, moving away from it means for supplying this product, so as to "follow" the progressive magnification of the spool during winding.
- the total stroke of the aforementioned assembly is not limited to the difference between the minimum radius and the maximum radius of a coil, but is provided long enough to create, between the fixed supply means and the frame-barrel-spindle assembly advanced to the maximum, sufficient free space, of the order of 1 to 2 meters. This space becomes available so that, without danger, the operator, when launching the machine, can come and recover the front end of the sheet product on the feeding means, and bring this end directly onto that of the two pins of the reel which is in its immediate vicinity.
- the design of winding machine object of the invention thus provides a considerable advantage, which cannot be obtained in the current state of the art.
- the carriage carrying the feeding means moves back to adapt to the growth in the diameter of the coil, but this carriage cannot move back enough to create, between itself and the rest of the machine , the space necessary for operator intervention.
- the race of Backing up of the carriage is limited by the usual presence, upstream of this carriage, of equipment belonging to the production and processing line for the sheet product. It is also not possible to create a large free space upstream of the trolley, to allow the trolley to retreat over an important stroke, because in this case the sheet product should cross a significant distance without being guided or supported, which would be very detrimental to the quality of the winding produced by the machine.
- the reel object of the present invention has an additional advantage, arising from the above.
- it is necessary to leave the carriage with a recoil stroke which corresponds at least to the half-diameter (or radius) of the largest wound coil, so that the carriage can move back enough to allow the constitution of a full coil of this maximum dimension.
- Such a retraction of the carriage has the immediate consequence that the path of the sheet immediately upstream of the rewinder, and the angles of interlocking of the sheet entering the rewinder, are modified during the retraction of the carriage, which has as consequence of disturbing the measurement of sheet tension and is sometimes the cause of annoying folds and winding defects.
- the reel object of the present invention in which the supply means, having become fixed, can be integrated into the set of cylinders located at the outlet of the production machine, the winding conditions being thus made constant and can be optimized.
- the winder object of the present invention comprises not only a considerable ease of access, but also better winding conditions.
- the reel design according to the invention also has a number of additional advantages:
- the fixed supply means can be integrated at the output of the production machine, which precedes the winder, the support of these supply means can itself be easily integrated into the frame of said machine exit, which is studied on modern machines so that the sheet can pass through the operator in a simple and safe way.
- the introduction of the sheet is already done in a simple way until the exit of the feeding means, and moreover it is no longer necessary to cross the winder since 1 operator is then close to the first spindle encountered (in the direction of travel of the sheet) of the rewinder.
- the introduction was done in a simple manner only upstream of the carriage, and the difficulties arose for the introduction of the sheet into the winder.
- the invention is thus indisputably advantageous for a manual introduction of the sheet, but it goes without saying that this invention is also particularly advantageous in the case of production machines whose outputs are equipped with automatic introduction systems by belt, rope or air cushion, since it is sufficient in this case to automatically advance the sheet already to the exit of the feeding means, and then it is no longer necessary to pass through the winder.
- the arrangement which is the subject of the present invention is also particularly advantageous, in relation to the use of a cutting device, in particular a cutting device located between the tension measuring cylinder and the contact cylinder.
- a cutting device in particular a cutting device located between the tension measuring cylinder and the contact cylinder.
- the simple introduction of the sheet is done directly up to, and including from, the cutting blade which can be used without danger for operators, so as to achieve a clean transverse cut of the sheet, before putting the end of this sheet on the winding spindle (the cut part of the sheet being discharged either to the ground laterally, or directly to a crusher located under the machine).
- the winder which is the subject of the present invention is also particularly advantageous when the unloading of the full reel is found, which is more and more often the case, provided by a device known as a guided or remote-controlled carriage, the functions of which are to return automatically or not near the spindle at the front of the reel, when the full reel has been transferred there by rotation of the barrel, to pick up the full reel, and possibly to deposit, in place of this taken reel, a new empty reel core.
- a guided or remote-controlled carriage the functions of which are to return automatically or not near the spindle at the front of the reel, when the full reel has been transferred there by rotation of the barrel, to pick up the full reel, and possibly to deposit, in place of this taken reel, a new empty reel core.
- the supply means being fixed
- the contact cylinder can be fitted with very flexible pressure members without friction, the frame-barrel-pin assembly being meanwhile, independently moved slowly forward depending on the growth of the coil diameter.
- this mobile frame-barrel-pin assembly can be done by means of various motorized, mechanical or electromechanical or hydraulic actuation devices, such as hydraulic cylinders.
- the actuation device here consists of an assembly comprising at least one electric stepping motor, and at least one ball screw driven by the motor.
- the winder comprises an assembly generally designated by a reference 1, comprising a frame 2, a barrel 3 rotatably mounted on the frame 2 around a horizontal axis 4, and two parallel winding pins 5 , each with a horizontal axis 6, diametrically opposite and carried by the barrel 3.
- Motorized members not shown, ensure the rotation of the barrel 3 around its axis 4, and the rotation of each pin 5 around of its axis 6.
- the assembly 1 formed of the frame 2, the barrel 3 and the two pins 5 is mounted movable in translation, on rectilinear horizontal guides 7 carried by a fixed base 8 of the machine.
- Means not shown such as a stepping electric motor associated with a ball screw, ensure the displacement in translation of the assembly 1 along the guides 7, either forwards (arrow FI), or towards the 'rear (arrow F2), the terms "front” and “rear” being defined here by reference to the general direction of travel (arrow F) of the sheet product 9 to be wound.
- a fixed assembly 10 used for supplying the sheet product 9, coming from a manufacturing machine (not shown) located upstream.
- the assembly 10 comprises a succession of cylinders or rollers 11, 12, 13 and 14, on which the sheet product 9 is guided.
- a tension measuring cylinder 13 is provided on the front side of the assembly 10, which surmounts a contact cylinder 14.
- a cutting device 15 provided with cutting members movable transversely to the direction of advance of the sheet product 9.
- the mobile assembly 1 formed from the frame 2, the barrel 3 and the two pins 5 is movable in a controlled manner, over a relatively large stroke, between a rear position very close to the fixed assembly 10 serving for the supply of the product in strip 9, and a front position relatively distant from said fixed assembly 10, all intermediate positions which can naturally be occupied.
- a relatively large free space E of the order of 1 to 2 meters, is provided above the base 8, between the mobile assembly 1 and the fixed assembly 10.
- an operator can thus take place in this free space E for, when launching the machine, grasp the front end 16 of the sheet product 9, and introduce it on one of the pins 5, more particularly the spindle located in the winding position, that is to say the most rear.
- the winding process of this product 9 can begin.
- the mobile assembly 1 is first moved back, until the pin 5 considered comes to bear on the contact roller 14, located at its height (see FIG. 3).
- the spindle 5 is rotated, so as to cause the sheet product 9 to be wound around this spindle 5, to form a coil 17 (see FIG. 4).
- the diameter of the coil 17 increases progressively, which is compensated by a corresponding slow advance of the mobile assembly 1.
- the cutting device 15 intervenes.
- an auxiliary carriage 18 movable on the base 8 can be approached from the movable assembly 1, from the front thereof, to come and take the full coil 17 and possibly deposit on the barrel 3, instead , a new empty reel core.
- the mobile assembly 1 having also carried out a recoil, bringing the spindle coming into the winding position against the support cylinder 14 during the last rotation of the barrel 3, the machine is ready to execute a new cycle identical to the previous one.
