Definitions
- the present invention concerns a blade-holder head for cutting textile or cloth materials on automatic spreading tables.
- a head that uses a rectilinear blade having alternate movements.
- This head besides being susceptible to translations, in parallel and orthogonal planes with respect to the spreading table, is also susceptible to rotations around a vertical axis to be able to change the forward movement of the blade and make the cut according to the desired trend.
- the blade does in any case need to be correctly supported, guided and lubricated to ensure and maintain its cutting efficiency. Furthermore, because the head has a revolving part, or rotor, to permit the above-mentioned directionality of the blade with a degree of freedom of 360°, it is not easy to convey the lubricating fluid to the cutting end of the blade.
- the object of the present invention is to propose a blade-holder head able to support, guide and lubricate or cool the cutting blade in a perfect way, while at the same time improving the lightness and the overall dimensions of the head itself.
- Said object is achieved using a blade-holder head according to claim 1.
- the dependent claims describe preferred embodiments of the invention.
- FIG. 1 is an axial section of the blade- holder head according to the invention.
- FIG. 2 is a perspective view of the head from below.
- reference numeral 1 indicates a blade-holder head according to the invention as a whole.
- the blade-holder head 1 is suitable for supporting a rectilinear blade 2 having alternate movements along a blade axis X for cutting textile or cloth materials stretched on a spreading table.
- the blade-holder head 1 comprises first blade guide means 10 suitable for supporting the cutting blade 2 through a plurality of contact points distanced along the blade axis X.
- the first blade guide means 10 comprise a vertical plate 12 from which extend three blade supports 13 distanced in height, each bearing a pair of rollers with horizontal rotation axis or other means of blade support and guide.
- the first blade guide means 10 are fixed to a guide support body 14, e.g., by means of the vertical plate 12.
- a presser disc 16 is connected at the bottom to said blade support body 10 with the possibility of alternate axial movement by means of a respective actuator (not shown) .
- Said presser disc 16 supports second blade guide means 18 aligned with said first blade guide means and suitable for supporting and guiding the lower end of the blade 2.
- a command unit 20 is fitted on an upper crosspiece 22 of the guide support body 14.
- Said command unit 20 comprises a rotor body 24 suitable for rotating around said rotation axis parallel with said blade axis, and a stationary outer sleeve 26, placed coaxially around said rotor body 24.
- friction reduction means e.g., at least a ball bearing 30.
- the rotor body 24 comprises a hollow guide unit 32 bearing third blade guide means 34, i.e., upper blade guide means, suitable for supporting and guiding an upper portion of the cutting blade 2.
- third blade guide means 34 i.e., upper blade guide means, suitable for supporting and guiding an upper portion of the cutting blade 2.
- the rotor body 24 also comprises, for its rotation, an outer flange 36 bearing a pulley 3,8, the stationary outer sleeve 26 being placed between said pulley 38 and said hollow guide unit 32.
- the outer flange 36 has a concave shape, i.e., cup shape, defining, with the hollow guide unit 32, an annular seat on which is housed the stationary outer sleeve 26.
- the outer flange 36 has a threaded side wall 36' for its screwing up into a respective threaded seat 22' made in the upper crosspiece 22 of the guide support body 14.
- the guide support body 14 has an overturned "L" shape.
- said body comprises a side 14' with vertical extension, to which the first blade guide means 10 are fixed and having a height substantially equal to that of said first blade guide means, and the upper crosspiece 22 which extends from the upper end of said side 14' .
- the blade- holder head 1 has a lubrication circuit suitable for lubricating the cutting end of the blade 2.
- Said circuit comprises an entrance hole 50 made in the stationary outer sleeve 26 and suitable for coupling with the lubricant inlet fitting 52.
- Said entrance hole 50 is in fluidic communication with the annular lubrication chamber 44 made in the outer sleeve.
- a first lubrication duct 54 is made in the rotor body 32 and in fluidic communication with said annular chamber 44.
- a second lubrication duct 56 in fluidic communication with said first duct 54 extends through the guide support body 14.
- a third lubrication duct 58 is made in the presser disc 16 in fluidic communication with said second duct and coming out next to the cutting end of the blade 2.
- the second lubrication duct 56 comprises a coiled tube 56' which extends from the upper crosspiece 22 to the presser disc 16.
- said coiled tube 56' is connected to a coiled tube fitting 60 accommodated in the upper crosspiece 22 and communicating with the first lubrication duct 54.
- the other end of the coiled tube 56' is connected to a disc inlet fitting 62, installed on the presser disc 16.
- the third lubrication duct 58 comprises two branches 64 which extend from the disc inlet fitting 62 and which come out on opposite sides of the blade.
- the described blade-holder head therefore permits lubricating the cutting end of the cutting blade with a particularly lightweight and compact head structure, where the stationary part, , wherein the lubrication chamber is made, is reduced to the sole outer sleeve.
- Such sleeve as can also be appreciated by the drawings, has a small axial dimension, which does not affect the total height of the head.
- T h e use of the coiled lubrication tube- advantageously permits the axial movements of the presser disc to which it is connected.
- the reduction in overall height dimensions of the command unit permits optimizing the blade support and guide, increasing the height extension of the first guide means and/or the number of contact points with the blade.
