DESCRIPTION of the invention having as TITLE:

AUTOMATIC FIXED AXIS WINDER

SUMMARY

System for automatic winding in reels on existing and / or new fixed axis winders, of strips of various sizes and materials based essentially on the use of a movable arm carrying a pair of gluing rollers on which the strip to be wound slides and which they are placed alternately in contact with the two fixed axis reels passing the tape from the finished reel to the waiting reel.

DESCRIPTION

The present invention relates to a coordinated set of components known in the art suitable to give rise to a device, hereinafter referred to as a "winder", for the automatic winding of strips of various materials into reels on fixed axis winders of any size.

Materials such as paper, plastic films, films, fabrics, leathers, flexible metal laminates, etc., are produced using “continuous” high productivity machines.

The drawback of this processing is the need to wrap the product, at the exit of the line, in reels of a predetermined diameter. In the case of reels wound on fixed axis winders, once this diameter is reached it is necessary to slow down or stop the production of the tape to allow the removal of the finished reel and the preparation of a new reel on which to wind the tape.

The operation entails slowdowns in the production process, introducing economic losses that are all the more burdensome the higher the productivity of the plants.

The present invention, integrated in any continuous tape production system, allows the finished reel to be removed and the new reel to be set up automatically without having to slow down or stop the continuous production of the tape while using fixed axis winders. Similar devices which are integrated or to be integrated in continuous-type systems for the production of flexible tapes of any material and size are not known in the art.

The purpose of the present invention is to eliminate interruptions or slowdowns in the production process of any material produced in strips, due to the need to remove the reel wound on finished fixed axis winders and to prepare the new reel for the production of a new reel.

Another object of the present invention is that of being able to be integrated into any existing system for the continuous production of material in strips already existing and functioning or still to be produced.

A further object of the present invention is to be able to be adapted to any continuous production system of material in strips with the simple variation of the dimensions and operating parameters, such as production speed of the strip, maximum required diameter of the finished product reels, etc.

A further purpose of the present invention is to obtain the advantages deriving from the use of moving axis winders at significantly lower costs.

With reference to tables 1, 2, 3, 4, 5, 6, 7, 8 and 9 a constructive and functional description of the present invention is provided below, by way of non-limiting example.

The present invention consists of a frame (e) (e ') which acts as a support for all the other components and / or accessories.

In particular, the active device of the present invention are the movable arms consisting of the gluing roller support translation actuator (m) (m '), the gluing roller support (h) (h'), the gluing rollers (f) (f), by the belt cutting blade actuators (i) (ϊ ') (I) (Ι'), by the belt cutting blades (g) (g ') and by the idle deviating rollers (n) (η'). These movable arms are hinged in a suitable position to the frame (5) (5 ') and are rotated by the actuators (d) and (d'). The present invention is completed by the motorized upper (b ') and lower (b) reels, the adhesive elements placed on the surface of the reels (c) (c'), the idle deviating rollers (q) (q ') (q ") ( q '") and the sensors with maximum diameter (p) (ρ'). With reference to tables 2, 3, 4, 5, 6, 7, 8 and 9, the description is provided below, as said description is organized in seven dynamic steps successive, marked by numbers from 0 (zero) to 6 (six), indicating the corresponding configurations assumed by the present invention in progressive sequences: - step (0) relating to the configuration represented in table 2 in which the cycle is started manually by adhere the tape (a) to the lower reel (b ') by means of the adhesive elements (c'); the lower reel (b ') drags the tape (a) which begins to be wound on the reel;

- step (1) relating to the configuration represented in table 3 in which the movable arms are placed in a horizontal position or in any case such as not to interfere with the formation of the coil (ο ') by the actuators (d) (d') and the coil lower (ο ') is nearing completion;

- step (2) relating to the configuration represented in table 4 in which the sensor (ρ ') of maximum diameter (r) signals the approach of the reel change; the movable arms are rotated upwards by the actuators (d) (d ') so as to place the lower gluing roller (f) near the upper reel (b);

- step (3) relating to the configuration shown in table 5 in which, by remaining the movable arms in such a position as to place the lower gluing roller (f) near the upper reel (b), the gluing roller support translation actuators ( m) (m ') translate the gluing roller supports (h) (h') until the gluing roller (f) adheres to the upper reel (b); thanks to the action of the upper reel adhesive elements (c) the tape (a) is dragged by the motorized upper reel (b) and begins to wind on the reel; after a suitable time, the lower ribbon cutting blade actuators (I) (Γ) activate the lower ribbon cutting blade (g ') which cuts the ribbon (a) as shown in table 5, releasing the lower reel (ο') and allowing the tape (a) to wind freely on the upper reel (b); - step (4) relating to the configuration shown in table 6 in which the movable arms are placed in a horizontal position or in any case such as not to interfere with the formation of the coil (o) by the actuators (d) (d ') and the coil superior (o) is nearing completion;

- step (5) relating to the configuration represented in table 7 in which the sensor (p) of maximum diameter (r) signals the approach of the reel change; as the set diameter approaches, the movable arms are rotated downwards by the actuators (d) (d ') so as to place the upper gluing roller (f) near the lower reel (b');

- step (6) relating to the configuration shown in table 8 in which, by remaining the movable arm in such a position as to place the upper gluing roller (f) near the lower reel (b), the gluing roller support translation actuators ( m) (m ') translate the gluing roller supports (h) (h') until the upper gluing roller (f) adheres to the lower reel (b); thanks to the action of the lower reel adhesive elements (c '), the tape (a) is dragged by the motorized reel (b') and begins to wind on the reel; after a suitable time, the upper belt cutting blade actuators (i) (i ') activate the upper belt cutting blade (g) which cuts the belt (a) as shown in table 8, releasing the upper reel (ο') and allowing the tape (a) to wind freely on the lower reel (b); the cycle then continues as illustrated in step (1).

Ultimately the present invention, by virtue of the movable arms described carrying a pair of gluing rollers (f) (f) and the simple application of adhesive elements (c) (c ') on the surface of the motorized reels (b) (b') , allows the automatic winding of the coils wound on fixed axis winders of tapes of any flexible material and of any size, coming from continuous plants allowing automatic reel change eliminating the need to slow down or stop production.

The present invention can be realized in another way while maintaining the inventive concept underlying it, being able to replace every detail with another technically
