Description
- The present invention relates to a table especially usable for the blade cutting of leather, hide and synthetic materials.
- More in particular, 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.
- It is known that in the industrial production of leather and hide articles, typically shoes but also bags, belts and the like, the multiple operating steps are carried out with the aid of specific machines and relevant equipment. With special and non-exclusive reference to shoes, 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. Larger types of 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. In any case, 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. Considering the countless shapes and sizes of shoes it is therefore necessary to set up as many dinking dies, for covering all the requirements and having them at hand so as to reuse them as needed, according to the market requirements. This solution therefore implies the need of making countless dinking dies, causing a considerable lock-up of capital; the same dinking dies, moreover, require a selective storage that requires large spaces.
- 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. Before the cut, 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.
- On the contrary, 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 the machine a cutting size similar or a little larger than that of the traditional die cutting machines with travelling arm.
WO 2005/102 628 A1 discloses a table for blade cutting of materials according to the preamble of claim1. - 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.
- More in particular, 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 the arm carrying the cutting unit is fixed, globally making a very simple structure.
- Last but not least, 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.
- These and yet other objects are achieved by the table for blade cutting of materials as claimed in claim 1. Additional advantageous features of the invention are recited in the dependent claims.
- These as well as further features of the table for blade cutting of the present invention shall be better understood from the following detailed description, wherein reference is made to the annexed drawing tables showing a preferred and non-limiting embodiment thereof, wherein:
-
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 5 shows a schematic perspective side view of the same cutting table; -
figure 6 show, schematic views of an alternative embodiment referred to the connection of the arm carrying the cutting unit to the relevant sliding support. -
figure 7 shows a table which is not according to the invention, as thebeam 24 does not develop in a vertical direction and the rectilinear are not fixed to the front of the beam - With reference to said figures, the table for blade cutting of the present invention, globally indicated with
reference numeral 10 infigures 1 and2 , comprises a box shapedbase 12 that constitutes the support for a workingsurface 14, illustrated in detail infigure 3 . -
Base 10 seats the moving means, per se known, of anarm 16 and of the cuttingunit 18 moved along the arm itself. - According to the invention, 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 workingsurface 14 is advantageously defined by aplate 20 provided with parallel openings with horizontal and vertical development; said working surface is surmounted by asheet 22 of synthetic material such as nylon, in one or more pieces, that makes up the support surface for the material to be processed. Saidsheet 22 is constrained in a known manner to the underlying structure forming the workingsurface 14. - Along one of the larger sides of the latter there is fixed a
beam 24, arranged orthogonally relative to the surface itself and to theoverlying sheet 22;beam 24, the height whereof is by way of an example similar to that of the structure forming the workingsurface 14, may be directly fixed to the latter by welding or equivalent retaining means, or constrained in the same way to anintermediate element 26 with substantially semi-circular profile, extending longitudinally by an extent equal to or slightly less than, that of the beam itself. In the exemplary embodiment of the figures,beam 24 protrudes from at least one front of the structure forming the workingsurface 14 and theintermediate element 26 substantially aligns with the opposite ends of the beam itself. As a whole, both the longitudinal extension ofbeam 24 and that of theintermediate element 26 are preferably larger than the length of the larger side of the workingsurface 14, relative whereto they protrude from both ends. Theintermediate element 26 defines a cradle seat, arranged at the bottom relative tosheet 22. - The outer front, indicated with reference numeral 24' of
beam 24, is slidingly coupled to acarriage 28, wheretoarm 16 is connected; the latter extends crosswise and parallel abovesheet 22 and extends yup to protrude from the opposite larger side of the structure forming the workingsurface 14.Carriage 28 that carries arm, 16 slides horizontally onconventional guides 30 constrained to the outer front 24' ofbeam 24 by the effect of anelectrical motor 32.Arm 16 comprises a first vertical portion 16' of connection with the horizontal portion thereof, developed abovesheet 22; said arm, for example with quadrangular section, comprises at least oneface 34 that defines a plane oriented vertically relative to the workingsurface 14 and to theoverlying sheet 22; alongface 34 ofarm 16 there are arrangedlinear guides 36, per se known, wherealong a cuttingunit 18, equally known, is moved. The free end ofarm 16, which protrudes on the front the operator has access to, is protected by a conventionaltransparent screen 40 or the like. - The length dimensions of the working
surface 14, in particular ofsheet 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 infigures 1 and2 , correlated to the cutting unit 38, through which the patterns to be obtained by shearing of the material placed onsheet 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 workingsurface 14. The back side of the table of the present invention, in theportion comprising beam 24 and theintermediate element 26, is also suitably protected by ascreen 44; saidintermediate 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. - On the opposite front side of the machine, 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 interpolation of the two horizontal and vertical axes managed electronically, the first defined by
beam 24wherealong arm 16 slides, the second defined by said arm wherealong the cuttingunit 18 slides, allows all the necessary movements for the cutting unit itself for making rectilinear and mixed-linear shears. - 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. If the length of the working surface (14) is increased as desired, the installation of two or more arms (16) provided with as many cutting units (18) should be provided as well.
Figures 6 and7 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. - In said figures, the same reference numerals of the embodiment described above are used for common parts or components.
- According to the embodiment of
figure 6 , the structure that defines the workingsurface 14 and that comprises theintermediate 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 workingsurface 14; said extension, the height whereof is considerably shorter than the level ofsheet 22 of synthetic material, defines a vertical wall 50 on the front facing the sheet itself, wheretobeam 24 is fixed in a known manner. Therectilinear guides 30wherealong carriage 28 carryingarm 16 slides, are constrained on the exposed front 24' of saidbeam 24. - According to the table of
figure 7 , which is not according to the invention, the structure that defines the workingsurface 14 and that comprises theintermediate 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 ofsheet 22. - The top end of such extension 48' forms a
planar surface 52 wheretobeam 24 is fixed in a known manner. As in the embodiments described above, the rectilinear guides 30 where alongcarriage 28 carryingarm 16 slides, are constrained to the top exposed front of said beam. - As can be noticed from the above, the advantages achieved by the invention are clear.
- 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.
- Particularly advantageous is the solution that provides for containing
surface 14 and the beam for supporting and moving the projectingarm 16 carrying the cuttingunit 18 in a single block and self-bearing structure, with optional interposition of theintermediate element 26. This innovative combination of parts makes the cutting table of the present invention very simple under the construction profile and in any case reliable and sturdy. - Even if the invention has been described with particular reference to an embodiment thereof, made by way of a non-limiting example, several changes and variations will appear clearly to a man skilled in the art in the light of the above description.
