Definitions
- the present invention relates to a machine for unrolling and aligning ribbons of fabrics, synthetic materials and the like, particularly for conveyor-belt cutting units and the like.
- the processed materials are usually supplied in rolls, which are wound in a manner that is not perfectly aligned. Therefore, in order to feed 15 numeric-control cutting machines it is necessary to first align the ribbon of material unwound from the rolls.
- spreading units are devices capable of preparing mats of any number of layers by superimposing the material that is unwound and trimmed from a roll with an alignment system such as the one described earlier, and an unrolling system that eliminates the tensioning of the ribbon of material unwound from the roll.
- the aim of the present invention is to eliminate the drawbacks cited above, by providing a machine for unrolling and aligning ribbons of fabrics, synthetic materials and the like, particularly for conveyor-belt cutting units and the like, that is simple and efficient.
- an object of the present invention is to provide a machine for unrolling and aligning ribbons of fabrics, synthetic materials and the like that can be multiplied for several rolls of material to be fed in layers on the cutting unit.
- Another object of the present invention is to provide a machine for unrolling and aligning ribbons of fabrics, synthetic materials and the like that is highly reliable, relatively simple to provide and at competitive costs.
- a machine for unrolling and aligning ribbons of fabrics, synthetic materials and the like, particularly for conveyor-belt cutting units and the like comprising a supporting element that supports a roll of ribbon, a motorized device for unrolling the roll constituted by said ribbon, characterized in that it comprises a first assembly for reading the tension of said unrolled ribbon in order to adjust said motorized device so as to eliminate the tension of said unrolled ribbon, means for the lateral sliding of said unrolled ribbon, which is substantially free from tensions, for its alignment on a worktable, and a second assembly for reading the lateral deviation of said unrolled ribbon.
- Figure 1 is a side elevation view of a machine for unrolling and aligning ribbons of fabrics, synthetic materials and the like, according to the invention. Ways of carrying out the invention
- the machine for unrolling and aligning ribbons of fabrics, synthetic materials and the like generally designated by the reference numeral 1, comprises a supporting element 2, which supports a roll 3 of ribbon 4, a motorized device 5 for the unrolling of the roll 3 constituted by the ribbon 4, and a first assembly 6 for reading the tension of the unrolled ribbon 4 in order to adjust the motorized device 5, so as to eliminate the tension of the unrolled ribbon 4.
- the machine 1 further comprises means 7 for the lateral sliding of the unrolled ribbon 4, substantially free from tensions, for the alignment thereof on a worktable 8, and a second assembly 9 for reading the lateral deviation of the unrolled ribbon 4.
- the motorized device 5 comprises an unrolling roller 10, which can rotate about its own axis parallel to the axis of the roll 3 and on which the unrolled ribbon 4 is partly wound.
- the motorized device 5 further comprises first motor means 11 , which are associated with the unrolling roller 10 by means of a belt drive 11a.
- the first reading assembly 6 comprises at least one redirection roller 12, whose axis is parallel to the axis of the roll 3 and on which the ribbon 4 unrolled in output from the unrolling roller 10 is partly wound.
- the first reading assembly 6 comprises at least one lever 13 for supporting the redirection roller 12, which is pivoted at one end 13a to the redirection roller 12 and at the other end is associated rotatably with a fixed portion of the machine 1.
- the first reading assembly 6 comprises a sensor, not shown, for measuring the angular deviation of the supporting lever 13 under the action of the ribbon 4 with respect to a reference position for actuating the first motor means 11.
- the means 7 for lateral sliding comprise advantageously a first idle roller 15 and a second idle roller 14, which have parallel axes and have a variable center distance, and through which the unrolled ribbon 4 in output from the redirection roller 12 is inserted.
- the first idle roller 15 is associated rotatably with a fixed portion of the machine 1 and the second idle roller 14 is pressed toward the first idle roller 15 by a piston 15a to close and open the second idle roller 14 on the first idle roller 15.
- the first idle roller 15 and the second idle roller 14 are associated with a system of substantially straight guides 16 for their axial sliding.
- the axial movement of the first idle roller 15 and of the second idle roller 14 on the system of guides 16 occurs by way of second motor means 17, for example by means of a screw-and-nut coupling 18.
- the second reading assembly 9 comprises a set of photocells, not shown, for detecting the position of the edge of the ribbon 4 on the plane of the worktable 8.
- the second reading assembly 9 can comprise, as an alternative to the photocell system, a vision system, not shown, for detecting repetitive markings on the unrolled ribbon 4 in output from the first idle roller 15 and from the second idle roller 14.
- the ribbon 4 unrolled from the roll 3 can be moved laterally by virtue of the action of the axial movement of the first idle roller 15 and of the second idle roller 14, since it has no tension due to its unrolling.
- the machine for unrolling and aligning ribbons of fabrics, synthetic material and the like achieves fully the intended aim and objects, since it allows the unrolling and alignment of a ribbon from a roll in a manner that is simple and efficient, and can be multiplied for several rolls of material to be fed in layers on the cutting unit.
- the materials used may be any according to requirements and to the state of the art.
