Definitions
- Table for blade cutting of materials for example leather, hide and synthetic materials.
- the present invention relates to a table especially usable for the blade cutting of leather, hide and synthetic materials.
- the present invention relates to a table or bench for the blade cutting of materials suitable for making, typically and not critically, basic semi-finished parts for making leather shoes and articles in general.
- the table of the present invention is especially suitable for shearing tanned hide used to make shoe vamps and parts thereof.
- a basic operating step consists in cutting leather and/or hide, optionally synthetic and flexible materials, for obtaining shaped semi-finished parts with which the shoe vamps and the sole are later made. Shearing such natural materials, the shape and size whereof varies according to the type of animal they are obtained from, is mainly obtained with two different types of processes and on as many different machines.
- a first much widespread type of shearing of the material is carried out by dinking dies, on machines called die cutting machines; such machines may be, according to the smaller type, provided with travelling arm, angularly adjustable along a parallel plane and overlying that whereon the material to be sheared is placed.
- die cutting machines are defined with movable carriage or bridge and are provided with a working or cutting surface significantly larger than the die cutting machines with travelling arm.
- shearing the material requires the use of dinking dies, which consist of metal shaped frames, with cutting edge on the front intended for abutting the material itself.
- An alternative embodiment as regards the shearing of leather, hide and synthetic materials is obtained on the so-called cutting tables or benches, the size whereof generally is even larger and reaches many metres both in length and width.
- On the opposite sides defined by the larger sides of the cutting table there are arranged respective rails for the sliding of carriages that move at least one beam extended crosswise; the beam supports at least one cutting unit or blade, the movement whereof is managed by an electronic control.
- the material placed on the cutting table is selected in its parts to optimise the process and minimise the waste; this takes place thanks to the projection of the various patterns, mapped beforehand by the electronic system, on the material itself.
- This type of shearing is obtained on large machines only, therefore suitable for large productions; while having the advantage of excluding the resort to dinking dies, since the various patterns are stored to the operating system and, among the other things, they may be subject to quick update by the dedicated software, these cutting tables or machines require a considerable investment of capital, as well as large spaces for the installation thereof, in the production factories.
- the need currently felt is that of combining the advantages of blade cutting with those of a limited size of the machinery; the desirable solution, in other words, is to eliminate the dinking dies with all the relevant costs and drawbacks, while keeping on die machine a cutting size similar or a little larger than that of the traditional die cutting machines with travelling arm.
- the object of the present invention is to provide such solution by making a cutting table or bench having limited size and operation corresponding to that of large sized and expensive tables.
- the object of the invention is to provide a table as defined above wherein the working surface consists of a single element or single block whereto die arm carrying the cutting unit is fixed, globally making a very simple structure.
- another object of the invention is to provide a cutting table wherein said arm is developed projecting on the working surface for ensuring the optimum position of the material to be sheared.
- a further object of the invention is to provide the users with a table for blade cutting of leather, hide and synthetic materials suitable for ensuring a high level of resistance and reliability over time, also such as to be easily and inexpensively constructed.
- the table for blade cutting of materials comprises a support base for a working surface with quadrangular plan whereon at least one cutting unit works, carried by one or more arms, and which is essentially characterised in that the structure forming said working surface consists of at least one self-bearing single block of metal or other suitable material that comprises a beam supporting said arm.
- figure 1 shows a schematic perspective front view of the table for blade cutting of leather, hide and synthetic materials of this invention
- figure 2 shows a schematic perspective side-back view of the same cutting table
- figure 3 shows a schematic perspective top view of the block constituting the working surface and at the same time, the support for the arm carrying the cutting unit
- figure 4 shows a schematic side and partial view of the same cutting table
- figure 5 shows a schematic perspective side view of the same cutting table
- figures 6 and 7 show schematic views of as many alternative embodiments referred to the connection of the arm carrying the cutting unit to the relevant sliding support.
- the table for blade cutting of t he present invention comprises a box shaped base 12 that constitutes the support for a working surface 14, illustrated in detail in figure 3.
- Base 10 seats the moving means, per se known, of an arm 16 and of the cutting unit 18 moved along the arm itself.
- the structure constituting the working surface 14 consists of an assembled and self-bearing metal single block, with quadrangular plan, made up of sheets preferably oriented orthogonally to one another, welded and/or bolted or it is made by casting.
- the upper front of working surface 14 is advantageously defined by a plate 20 provided with parallel openings with horizontal and vertical development; said working surface is surmounted by a sheet 22 of synthetic material such as nylon, in one or more pieces, that makes up the support surface for the material to be processed.
- Said sheet 22 is constrained in a known manner to the underlying structure forming the working surface 14.
- beam 24 arranged orthogonally relative to the surface itself and to the overlying sheet 22; beam 24, the height whereof is by way of an example similar to that of the structure forming the working surface 14, may be directly fixed to the latter by welding or equivalent retaining means, or constrained in the same way to an intermediate element 26 with substantially semi-circular profile, extending longitudinally by an extent equal to or slightly less than, that of the beam itself.
- beam 24 protrudes from at least one front of the structure forming the working surface 14 and the intermediate element 26 substantially aligns with the opposite ends of the beam itself.
- both the longitudinal extension of beam 24 and that of the intermediate element 26 are preferably larger than the length of the larger side of the working surface 14, relative whereto they protrude from both ends.
- the intermediate element 26 defines a cradle seat, arranged at the bottom relative to sheet 22.
- the outer front, indicated with reference numeral 24' of beam 24, is slidingly coupled to a carriage 28, whereto arm 16 is connected; the latter extends crosswise and parallel above sheet 22 and extends yup to protrude from the opposite larger side of the structure forming the working surface 14.
- Carriage 28 that carries arm, 16 slides horizontally on conventional guides 30 constrained to the outer front 24' of beam 24 by the effect of an electrical motor 32.
- Arm 16 comprises a first vertical portion 16' of connection with the horizontal portion thereof, developed above sheet 22; said arm, for example with quadrangular section, comprises at least one face 34 that defines a plane oriented vertically relative to the working surface 14 and to the overlying sheet 22; along face 34 of arm 16 there are arranged linear guides 36, per se known, wherealong a cutting unit 18, equally known, is moved.
- the free end of arm 16, which protrudes on the front the operator has access to, is protected by a conventional transparent screen 40 or the like.
- the length dimensions of the working surface 14, in particular of sheet 22 overlying it, are preferably comprised between 800 and 3500 mm; the width or depth ones are indicatively comprised between 500 and 1200 mm.
- the table for blade cutting of the present invention further comprises programming, displaying and projection means of known type, schematised with reference numeral 42 in figures 1 and 2, correlated to the cutting unit 38, through which the patterns to be obtained by shearing of the material placed on sheet 22 are determined; the latter is advantageously provided with through holes suitably positioned, wherethrough air is sucked starting from a vacuum pump placed at the bottom or in contact with the structure forming the working surface 14.
- the back side of the table of the present invention in the portion comprising beam 24 and the intermediate element 26, is also suitably protected by a screen 44; said intermediate element 26, according to its cradle shape, advantageously makes the suitable seat for seating the material to be sheared wound in a roll, that the operator can each time unwind.
- the material the semi-finished parts are obtained from can be oriented downwards, since arm 16 does not rest in any point or zone as it is protecting.
- the particular embodiment that envisages a single block and self-bearing structure for the working surface (14) also allows a modular use of the same; in fact, it is advantageously possible to constrain, along one of the respective smaller sides, two or more of said single block structures to one another, including the relevant beams (24) and any intermediate elements (26), for extending the length of the working surface (14) at low cost.
- Such constraint which may be made by welds, bolts and/or other suitable means, does not require other substantial structural modifications of the cutting table, except for the extension of the base or the set up of suitable supports for the added portion of the working surface (14).
- the arm (16) is unchanged too, but its possibility of longitudinal movement increases as it takes place along two or more beams (24) aligned and constrained to each other.
- FIGS. 6 and 7 schematically show views of as many possible alternative embodiments of the table for blade cutting of the present invention, referred to the connecting position of the arm carrying the cutting unit to the relevant sliding support.
- the same reference numerals of the embodiment described above are used for common parts or components.
- the structure that defines the working surface 14 and that comprises the intermediate element 26 forming the cradle seat is extended upwards, at the back end and adjacent to said cradle seat.
- Such extension is indicated with 48 and develops without interruption from the structure that forms the working surface 14; said extension, the height whereof is considerably shorter than the level of sheet 22 of synthetic material, defines a vertical wall 50 on the front facing the sheet itself, whereto beam 24 is fixed in a known manner.
- the rectilinear guides 30 wherealong carriage 28 carrying arm 16 slides, are constrained on the exposed front 24' of said beam 24.
- the structure that defines the working surface 14 and that comprises the intermediate element 26 forming the cradle seat is provided, adjacent said seat, with an extension 48' oriented upwards and of limited height, such as to align with or be slightly lower than the level of sheet 22.
- the top end of such extension 48' forms a planar surface 52 whereto beam 24 is fixed in a known manner.
- the rectilinear guides 30 wherealong carriage 28 carrying arm 16 slides, are constrained to the top exposed front of said beam.
- the table for blade cutting of the present invention allows shearing leather, hide and synthetic materials without the need of resorting to dinking dies, but using the technology of blade cutting with electronic mapping of the material and pattern projection; the whole correlated to a cutting unit with electronic management and handling but without the typical costs and overall dimensions of many cutting tables.
