Definitions
- the problem consists principally of the fact that the initial edge of a tape or a sheet, usually of plastic material, that is desired to wrap around the periphery of the roll, tends to escape without allowing completion of the turn to fix it to itself.
- glues or the like see US-A-3 901 757 to hold in position on the roll the beginning of the tape or sheet until complete wrapping involves an unavoidable deterioration of the section of strip of the roll involved by the glueing. Especially in the case of valuable materials the loss upon unpacking is an added cost poorly tolerated by users.
- the method is clearly inapplicable for rolls of material by nature difficult or impossible to glue.
- the general object of the present invention is to obviate the above mentioned drawbacks by providing a packing device for rolls which would allow rapid and accurate automatic packing thereof without the use of glue or the like to stop the beginning of the tape employed for packing.
- a packaging machine indicated generally by 10 comprises two powered rollers 11 and 12 for support and rotation of a roll 13, e.g. of cloth.
- a slide 14 conveys the roll from a known machine (not shown) for formation of the rolls by winding of a continuous strip.
- a device 15 for cutting the strip from which the roll was formed is placed along the slide 14 .
- Said cutting device is of the known art and therefore not shown.
- it can comprise a rotating circular blade moving transversely to the path of the strip as will be readily imaginable to those skilled in the art.
- a plane 16 is moved by a drive 24 between a raised stop position controled for positioning of the roll on the rollers 11 and 12 and an unloading position of the roll by the rollers. Said two positions are shown in FIG. 1 in unbroken and broken lines respectively.
- a moving pivoted arm 17 powered and bearing at the free end a packaging unit 28 comprising an unrolling device 18 for a tape 19 of plastic material, e.g. a heat welding film, fed from a spool 20.
- the unit 28 comprises also a welding and cutting head 21 sliding thanks to a powered guide 22.
- the arm 17 is equipped with an encoder 29 for detection of its angular position.
- the packaging unit 28 is connected to the arm by a pivot and connected to a kinematic mechanism 23 for its inclination in relation to the longitudinal extension of the end part of the arm 17 as a function of the rotation of the arm as will be clarified below.
- the kinematic mechanism can for example consist of a tie-rod 23 sliding on a system of pulleys under the effect of a weight 31 opposed by a drawing spring 32 as shown schematically in the drawings.
- a sensor which detects the arrival of the unit 28 at a roll to be packaged.
- Said sensor can be for example a proximity sensor 26 supported by the packaging unit 28 and provided in the form of a microswitch so as to detect the approach of the periphery of the roll.
- control device 27 e.g. electronic with cabled or programmed logic.
- a control device e.g. electronic with cabled or programmed logic.
- the roll In the use of the machine the roll to be packaged rolls along the slide 14 until it is positioned on the rollers 11 and 12.
- the cutting device 15 separates the roll from the strip from which it was wound.
- the powered rollers rotate the roll to wind the free terminal edge 25 and simultaneously the arm 17 is commanded to rotate until the sensor 26 detects the periphery of the roll while the feed device 18 unrolls the tape 19 so that its free end lies on the edge being wound as shown in FIG. 2.
- the tape 19 is thus gripped and pulled by the rolling of the edge 25 as may be readily seen in FIG. 3.
- the kinematic mechanism 23 orients the unit 28 so that the welding and cutting head is always substantially perpendicular to the surface of the roll regardless of the diameter thereof.
- FIG. 5 By way of example in FIG. 5 is shown the machine during packaging of a roll 13' of small diameter.
- the arm 17 is raised again and the roll is removed from the machine by rolling it along the inclined plane formed by commanding the actuator 24 to lower the plane 16.
- Rolling along the plane 16 can be started for example by stopping the rotation of the roller 12 while that of the roller 11 continues so as to supply to the roll a momentum which causes it to roll on the roller 12 toward the inclined plane 16.
- FIG. 6 shows schematically a different embodiment of the machine in accordance with the present invention.
- a packaging unit 28' (the rest of the machine being substantially the same as that of FIG. 1 it is not further shown nor described here) comprises a nozzle 30 for controled delivery of the glue for its spreading on the surface of a tape 19' already partly wrapped in the position of the subsequent overlapping on itself.
- a cutting head 21' sliding with a guide 22' performs the cutting of the tape after covering by the tape of the glued zone, thus completing the packaging.
- the tape 19' can for example be made of paper.
- the blocking of the movement of the roll at the end of the slide 14 to position it correctly on the rollers 11 and 12 can be secured by providing a vertical movement of the roller 12 to arrange itself momentarily in a higher position than the roller 11 so as to constitute a stop ledge for the roll and then move to the same height as the roller 11 for the packaging phase.
- the same vertical movement of the roller 12 by lowering it beneath the level of the roller 11 to make the roll pass over the roller 12.
- the roll 13 can be supported at the ends by rotating chucks moving along guides, first to carry the roll to the machine and then to remove it therefrom.
- the welding head 21 could also be provided integral with the unrolling device and then taken into contact with the part to be welded by means of another rotation of the arm 17.
- tape 19 can of course be of a different width than the roll, e.g. if smaller with prevalently only fixing function of the free end of the roll or if greater side edges folding on the ends of the roll. It is also possible to use several tapes arranged parallel to link the roll along various circumferences.
