Definitions
- Accessory apparatus for feeding sheets of material to be cut in numerically controlled machines (NCMs), and NCM comprising said accessory apparatus
- the present invention relates to an accessory apparatus for a numerical control machine.
- the invention relates to an apparatus for feeding sheets of material to be processed in blade cutting machines, for instance for cutting sheets of material such as fabrics for clothing and hide goods, footwear items, automotive and furnishing articles or non- woven fabrics, leather, natural or synthetic hides, synthetic materials and the like.
- the invention also relates to a numerical control machine for cutting at least one sheet or a multilayer of sheets of material to be processed comprising said accessory apparatus.
- Said numerical control machine is preferably of the type comprising:
- the material to be cut may be for instance a sheet of plastic material, a natural hide, a fabric, a non-woven fabric, a cellulose-based material and the like.
- the cutting may be performed on a unique sheet or on a plurality of sheets stacked upon each other so as to form what is known in the field as mattress.
- these machines are equipped with a conveyor belt capable of moving the sheet to be cut along a plane XY, which will be hereinafter also defined cutting table, and inside a cutting chamber, which is provided with cutting tool heads actuated by computerized means for processing the material.
- the sheet or sheets to be cut in the machine are unrolled from rolls or other supports which rest on independent racks, placed at a short distance from the mouth of the machine.
- the roll-holder structure Although other constructions are possible for the roll-holder structure, the most widespread is that of a frame with wheels equipped with a series of vertical bars; these support the rolls at different heights, so as to also allow the feeding of more sheets to the machine for forming a mattress.
- CN 204 607 21 1 U discloses a frame for supporting sheets of material, said frame being structurally independent and not connectable to the cutting machine.
- the technical problem underlying the present invention is to provide an accessory apparatus for feeding the sheet material, which replaces the above roll-holder structures, thus solving the above-mentioned drawbacks, and which in particular is slim and easy to be repositioned and/or stored in case of non-use.
- a further object of the invention is to provide a numerical control machine which integrates, at least in a use condition, an accessory apparatus for feeding sheets according to the above-mentioned features.
- the solution idea underlying the present invention is to provide an accessory apparatus which performs the function of the roll-holder rack directly fastened, in a fixed or removable manner, to the frontal portion of the cutting machine.
- an accessory apparatus for feeding sheets of material comprising at least two beams that are fixable, in a mounted configuration, to a numerical control cutting machine, wherein in said mounted configuration the beams develop in projection with respect to a frontal portion of said machine, said beams supporting, in spaced relation with respect to the frontal portion of the machine, at least two pairs of opposite main slots for supporting as many transversal support bars for holding a roll or another supporting element for supporting a sheet of material to be cut.
- the accessory apparatus may be removably associated with the machine; the beams may be for instance introduced in a releasable manner into suitable attachment seats obtained on the machine or on intermediate elements fixed to the machine.
- the entire accessory apparatus may be cantilever supported by the beams in the mounted configuration.
- This expedient allows an extremely quick mounting, since just the fixing of the beams is necessary to configurate the support structure. Furthermore, this solution allows a complete freedom of maneuver for the operators and/or the other machinery below the beams.
- discharge feet may be arranged, preferably at the distal end of the beams, to discharge part of the weight of the structure to the ground.
- the discharge feet may be hinged to the beam, so as to be brought to rest only in a mounted and/or operating configuration.
- two of the pairs of main slots are respectively placed below and above the substantially horizontal plane defined by the beams.
- the two pairs of slots may be overlapped.
- the axial dimension of the beam is advantageously used to fix a plurality of rolls, thus favouring the simultaneous unrolling of two rolls at different heights to define a mattress of several sheets.
- the accessory apparatus may advantageously comprise a plurality of attachments, still associable in opposite pairs on the length of the two beams.
- the attachments have the main slots for the attachment of the transversal support bars and may advantageously be removably associated to the beams.
- Each attachment preferably comprises: an upper wing on which a main slot is obtained; and a lower wing, on which another main slot is obtained.
- the attachments preferably comprise at least one secondary slot in addition to the above main slots.
- the secondary slots of opposite attachments on the two beams face each other for supporting a transversal guide bar having a guide function for the sheet of material unrolled from the roll. Said secondary slots are placed in a closer position to the beam and nearer to the machine with respect to one of the main slots formed on the corresponding attachment. Thus, the sheet unrolled from the roll supported by the main slots is then deviated by the transversal guide bar supported by the secondary slots, so as to take up the correct horizontal orientation which substantially corresponds to the plane defined by the beams.
- a secondary slot is provided for each main slot.
- the secondary slots are formed on a front wing of the attachments, said front wing being in a retracted position towards the inside of the apparatus with respect to the upper and lower wings.
- the attachments may be mounted in a plurality of different axial positions along the beam. In this way, it is possible to configure the accessory apparatus according to the number and position of the rolls to be used for a determined cutting operation.
- the attachments may have a coupling pin, preferably biased in a coupling position by elastic means, said pin being alternatively insertable into a plurality of holes of the beam.
- the attachments have a planar configuration, the slots being obtained as open cuts on the outer profile of the attachment.
- the slots have a substantially C-shaped configuration, with a lead-in feature in a position higher than the seat to define a stable gravitational balance of the transversal bar.
- the beams may advantageously slide in a telescopic manner with respect to the machine.
- the beams may be blocked in a plurality of different positions which are more or less extracted based on the axial extension needs linked to the number of rolls used in the planned cutting operation.
- the transversal support bars not necessarily must support a roll. Indeed, between two successive transversal support bars a support sheet may be laid as a hammock for a sheet of material to be cut folded on itself. As an alternative to the support sheet a rigid support plane with analogous function may be used. The sheet is then progressively fed and unrolled during the cutting operations of the machine.
- a numerical control machine for cutting at least one sheet or a multilayer of sheets of material to be processed comprising:
- processing area preferably defined by a chamber or room
- - tool heads adapted to operate on the sheet in said processing area; characterized in that it further comprises:
- the accessory apparatus may be a part of the machine, possibly also integrated thereto; or alternatively it may be a distinct apparatus associable with the machine in the use conditions.
- the above machine may comprise a front device equipped with a support plane for the sheets which is foldable between: a vertical rest position; and a horizontal operating position in which it is in substantial continuity with the conveying means.
- the beams of the accessory apparatus may be associated with the distal end of said plane; for instance, they may be introduced in a telescopic manner into lateral arms of the movable plane.
- the beams are mounted and/or extracted with respect to the plane when the plane itself is in the raised operating configuration.
- the accessory apparatus may be positioned in a lower position with respect to the plane of the machine.
- the machine may or not provide the above front device.
- the accessory apparatus mounted in a lower position may be horizontally movable between a retracted position, in which it is housed below said conveying means of the machine, and an extracted position in which it extends in front of the machine.
- the accessory apparatus does not clutter the volumes in front of the machine when it is in the rest configuration.

- Support motorized means for supporting the movable plane 14 for actuating said plane are provided between the two extreme positions.
- Said motorized means are step electric motors which are adjustable with particular precision and interlocked to the control unit of the apparatus 1.
- Said motorized means, and the related support guides are structured to actuate the movable plane 14 in roto-translation from a rest laying position and to make it take up an operating position in which it is partially above the proximal end 13 of the conveyor belt 6. In the rest position the plane 14 is folded away parallel to the lower frontal portion 20 of the frame F.
- the motorized plane 14 is configured to facilitate the feeding of a sheet 2 to be processed on the conveyor belt 6, said movable plane 14 being movably guided towards and away from the proximal end of the conveyor belt 6.

- the beams 51 are preferably made as metal sections having rectangular or square section, and are cantilever fixed to the machine 1 or to the movable plane 14.
- the attachments 54 are a plurality of pairs comprising a right attachment and a left attachment which are specular to each other.
- the attachments 54 of each pair must be associated facing opposite the two beams 51 and provide for different main 52 and secondary 55 slots, which are adapted to support the support 53 and transversal guide bars 56, respectively.
- the attachments 54 are removably mounted on the beams 51, so that in the various configurations of the apparatus 50 they can be used in a different number.
- Each attachment 54 is preferably made of metal sheet and thus has a substantially planar conformation. It has two wings, an upper one 54a and a lower one 54b, which are opposite and substantially specular to each other. Both wings have a main slot 52. Said slot is made as a C-shaped recess, preferably made by shearing, which leads to a lowered seat where the transversal bar 53 is housed.

- the frontal wing has two secondary slots 55, shaped analogously to the main slots 52 and also equipped with friction reduction means. Said secondary slots 55, as previously stated, are arranged to support a guide transversal bar 56, which is slightly shorter than the transversal support bars 53.
- the secondary slots 55 are arranged above and below with respect to the beam 51 and are closer to the beam with respect to the corresponding main slot 52.
- the transversal support bar 53 is positioned downstream with respect to the roll unrolled from the transversal support bar, and in a close position to the plane defined by the beams 51.
- the attachment 54 also comprises, on the outer face thereof, a rest flange 54d equipped with a flap and arranged to straddle the beam 51 which the attachment is associated with.
- a coupling pin 58 is introduced, which introduces into one of a plurality of equidistant holes 59 formed on the outer face of the beam 51.
- the coupling pin 58 thus allows fixing the attachment 54 in the desired position along the beam 51.
- the coupling pin 58 is equipped with elastic means which keep it in an inserted position within the selected hole 59.
- the accessory apparatus 50; 50’ is illustrated in the enclosed figures in two different embodiments, which are different only in the different attachment point of the beams 51. The foregoing description applies to both embodiments.
- the accessory apparatus 50 is associated with the end of the movable plane 14 when it is in the raised configuration.
- the plane defined by the beams 51 is substantially at the height of the plane of the machine 1, namely it is a feeding plane which is substantially continuous with respect to that of the conveying means
- the beams 51 are introduced, in this case telescopically, into the arms 60 of the movable plane, which are advantageously configured as hallow sections.
- the beams 51 may be blocked in a position which is more or less extracted with respect to the arms, according to the needs of use of the machine.
- the accessory apparatus 50’ is directly associated with the machine 1; in this case the beams 51 are introduced into a sliding seat below the conveying means
- the plane defined by the beams 51 is thus considerably below the plane of the machine 1, namely that of the conveying means 6.
- the machine 1 may not be provided with the front device 9 equipped with the movable plane 14.
- the accessory device 50’ according to the second embodiment may advantageously be brought to a retracted position which is completely housed below the conveying means 6, as illustrated in the enclosed figures 12 and 13.
- the machine 1 may also be equipped with two accessory devices 50; 50’, an upper one according to the first embodiment and a lower one according to the second embodiment. Said configuration is illustrated by way of example in figure 14.
- the extraction of the beams 51 may be motorized and possibly interlocked to the control unit of the machine.
