Definitions

  • the present invention relates to a cutting and punching device for sheet materials such as fabric, intended to be installed on an automatic cutting machine, controlled by a digital control.
  • This device is generally placed on a mobile assembly composed of a beam moving longitudinally on guide rails and above a cutting table and a carriage moving along the beam thus forming a coordinate system crossed.
  • the invention proposes to solve the technical problem of cutting a sheet or stacking of sheets (only a few sheets) by a vibrating metal blade while seeking at the same time the lowest possible weight, in order to be able to move the tool at very high speeds and accelerations, reduced dimensions, great simplicity in order to have the best possible reliability and the presence of a punch allowing to perforate the material.
  • the choice of a vibrating blade imposes several constraints such as a high vibration frequency which requires moving parts of very low mass, slaving of the rotation of the blade to the tangent of the cut profile, dimensions of the blade very weak and a possibility of raising and lowering of the blade in order to disengage it completely from the cutting plane, more precisely when changing profile to be cut.
  • the sharpening of the vibrating blade must be done automatically.
  • the present invention makes it possible to solve these problems for the first time and in a satisfactory manner with a cutting and punching device for sheet materials intended to be mounted movably on an automatic cutting machine, comprising a cutting tool and a tool.
  • punching characterized in that it comprises means for vibrating the cutting tool, means for vertically moving the cutting tool, means for rotating the cutting tool, means for sharpening the cutting tool, means for vertically moving the punching tool, means for rotating the punching tool and a support base on which all said means which are compactly grouped together are likely to be implemented simultaneously and independently of each other.
  • the cutting tool will preferably be a vertical blade and the punching tool a vertical punch.
  • said means for vibrating the cutting tool comprises a flywheel directly coupled to the shaft of an electric motor fixed inside a movable housing, a crank pin mounted on the external face of said flywheel, free to rotate, the position of which is eccentric relative to the axis of rotation of said flywheel and which has an open slot arranged radially in which a T-shaped tongue of a slide adjusted horizontally slides to slide freely and without turning on a hollow guide whose axis is concurrent with that of the flywheel, said slide coming to engage in the upper part of the blade while leaving free its rotation.
  • said means for vertically moving the cutting tool comprise a pneumatic cylinder, two guide columns held at their upper ends by a connecting piece, a compression spring disposed between the base and the mobile box containing the electric motor.
  • said means for rotating the cutting tool comprise a servomotor connected by a toothed belt transmission and two pulleys to the rotary guide driving said blade in rotation.
  • said means for sharpening the cutting tool comprise: - two abrasive tongues articulated around a common vertical axis fixed on a presser foot and kept apart by a spring so as to tangent the blade without touching it, - Inclined planes formed at the lower outlet of the guide and intended to tighten the tongues in contact with the blade when the latter is placed in the high position.
  • Said means for vertical displacement of the punching tool include: - a pneumatic cylinder fixed to the connecting piece, a guide removably attached to a rotary hub of the base, the lower part of said punching tool sliding through the guide and its upper part being centered in the end of the rod of the jack, - A compression spring arranged between the upper face of the hub and the lower face of the cylinder rod and through which the punch passes.
  • said means for rotating the punching tool comprise a motor, pulleys secured respectively to the hub and to the motor shaft on which a round belt is mounted.
  • Figures 1 to 5 show the different means constituting the device of the invention which are integral with each other via a base (4).
  • the base (4) is fixed on a mobile carriage (2), which moves on a beam (1) by means of rollers (3).
  • the vibration of the vertical blade is achieved by the transformation of a continuous rotational movement into an alternating rectilinear movement. Vibration means are used for this with an eccentric device.
  • flywheels which are directly coupled to the shaft of an electric motor (7).
  • the whole is fixed inside a mobile box (6) which slides vertically along the two guide columns (5).
  • a crankpin 15
  • free to rotate the position of which is eccentric relative to the axis of rotation of the flywheel (14).
  • this eccentricity depends on the amplitude of the vibration of the blade.
  • This crankpin comprises an open slot arranged radially in which a tongue of a slide (16) slides.
  • a hollow guide (19), of square section, is fixed vertically on the upper part of the housing (6). Its axis is concurrent with that of the steering wheel (14). On this guide, there is a slide (16), adjusted so that it can slide freely on the guide (19), without however having the possibility of turning around the latter (due to the square section).
  • the slide (16) is composed of several active parts.
  • the first consists of a vertical sleeve of square section, adjusted on the guide (19).
  • the second consists of a tongue (17) secured to the lower base of the sleeve, the ends of which have different shapes.
  • This tongue (17) has the shape of a T and is arranged in such a way that it can slide in the slot of the crank pin (15).
  • the crank pin (15) When the flywheel (6) is rotated, the crank pin (15), by its eccentric position, drives the tongue (17) and thus the entire slide (16); the tongue (17) being able to slide horizontally freely. This is how the rotational movement is transformed into a vibrational movement.
  • the other end of the tongue (17) in T has a shape such that it can snap into the upper part of the vertical blade (20) to drive the latter in the vibration movement while leaving free its rotation.
  • Figure 11 shows a complete blade, with its particular shape at its point of attachment.
  • the blade (20) is guided vertically by a slide (21), which slide is itself guided vertically in a guide (22), mounted in free rotation on the base (4).
  • the guide section is square.
  • the rotation of the slide (21) relative to the guide (22) is thus impossible: only the vertical translation of one relative to the other is possible.
  • the length of the slide (21) is such that the blade does not bend under the action of the cutting forces.
  • the guide (22) is mounted in the base (4) with a ball bearing.
  • the cylinder (pneumatic cylinder) (8) is held in position on the connecting flange (13) via the plate clamping (10).
  • This clamping plate (10) ( Figure 14) is in fact placed above the cylinder (8), which comprises at its upper end a shoulder, said shoulder being housed in a bore of the flange (13).
  • a conventional O-ring type seal is inserted between (10) and (8) so as to avoid air leaks. Compressed air is admitted through the fitting (11).
  • the clamping plate (10) is fixed by means of two knurled head screws (12) (see Figure 2).
  • the slide (21) also has the function of carrying, in its lower part, a presser foot (29), which foot is necessary for pressing or pressing the material to be cut on its cutting support.
  • This foot must take into account the variable heights of the materials to be cut.
  • the up / down movement of this foot is mechanically linked to that of the housing (6) which avoids the use of a separate actuator.
  • the vertical displacement device of the foot (29) comprises a return rod (18) guided vertically in the bore of the upper guide (19) and a compression spring (32) disposed inside the bore, au- above the return rod (18). This spring therefore pushes the return rod (18) down until it reaches its lower stop constituted by a small shoulder.
  • the lower end of the rod (18) has the shape of a coil which comes to engage on a disc secured to the upper part of the slide (21).
  • This coupling device allows a connection in vertical translation of the rod (18) relative to the slide (21) while leaving the rotation of the slide (21) completely free.
  • the spring (32) pushes the rod (18) downward, which pushes the slide (21) and its foot (29) against the material deposited on the cutting table.
  • the presser foot (29) will adapt to the height of the cut material and will cause a contact pressure depending on the setting of the spring (32).
  • the blade independently of its vibrating movement, can move up and down so that it can disengage or penetrate completely into the material to be cut. In fact, all movements outside the cut are made with the blade in the high position.
  • means are used for vertical displacement of the blade comprising a pneumatic cylinder (8) whose cylinder is fixed to the connecting piece or flange (13) holding the two guide columns (5).
  • the piston meanwhile, is fixed on the vibration housing (6). Compressed air is only sent into the cylinder through its upper end through the fitting (11). It is a single acting cylinder.
  • the return movement to the high position is provided by a compression spring (31), which is arranged between the base (4) and the lower part of the housing (6) and between the columns (5).
  • the vertical guidance of the housing (6) is ensured precisely by the two guide columns (5).
  • rotation means comprising a servo-motor (26) controlled in position and speed, a first pulley (25) mounted on the shaft of said motor (26), a second pulley (23) mounted on the lower part of the guide (22) and a toothed belt transmission (24) connecting the two pulleys (23,25) and thus driving the blade (20) in rotation.
  • the servo motor (26) is mounted vertically on a support (27) articulated relative to the base (4). This allows tighten the belt (24) between the two pulleys (23,25) using for example a screw (28), said screw screwing into the base (4) and whose head comes to bear on the articulated support (27) located just opposite. By unscrewing the screw (28), the articulated support (27) is pushed back.
  • a punching tool is used for this, coupled to the cutting tool and which is also managed by digital control.
  • the principle is based on the use of a vertical punch (35) which is raised or lowered by a pneumatic cylinder (30) and whose rotation is ensured by the motor (26).
  • this motor is the same as that which ensures the blade rotation. This avoids the use of an additional motor and contributes to the compactness of the assembly.
  • the punch (35) is slidably mounted in a guide (41), which guide is mounted in a hub (37).
  • This hub (37) is guided in rotation in the base (4) by a ball bearing.
  • a hooking means (not shown), in the form of a clip for example, secures the guide (41) with the hub (37) so that it is rotated but that it can also be disassembled easily. This is necessary for the punch change in which case the guide (41) must be removed.
  • a pulley (38) is integral with the hub (37).
  • Another identical pulley (40) is integral with the motor shaft (26). It is fixed on the same hub as the pulley (25), but above the latter.
  • the two pulleys (38) and (40) are connected by a round belt (39) under tension which thus transmits the rotation of the motor (26) to the hub (37) and therefore to the punch (35).
  • a single-acting cylinder (30), with compressed air, is hooked, by its upper end, to the flange (13).
  • the end (33) of the cylinder rod receives a small ball bearing so that its central part (34) can rotate freely.
  • the end of the punch (35) is such that it is centered in this central part (34).
  • a shoulder, located on the punch (35), of diameter much larger than that of the punch, serves as a vertical stop.
  • a compression spring (36) is placed between on the one hand the upper face of the hub (37) and on the other hand the lower face of the rod of the jack or of the shoulder situated at the end of the punch (35) . This spring exerts a force which keeps the punch (35) pressed against the end (34) of the jack rod.
  • the punch (35) is guided in rotation only by the spring (36), which rests on the hub (37). It is therefore a friction guide.
  • the drive torque is all the greater when the spring is compressed, which goes in the right direction, since the torque must be maximum when the punch is in the low position, that is to say in the matter.
  • the numerical control program establishes the following actions: - movement of the device above the chosen point, blade in high position, - high speed rotation of the motor (26) - lowering of the punch (35) - rise of the punch - engine stop (26).
  • This punching device has the following advantages: - use of a single motor for two completely different functions - maximum compactness - ultra-simplified punch, requiring no special rotational drive means (drive by friction) - very simple assembly and disassembly requiring no tools - very good reliability.
  • the invention therefore also provides means for ensuring this sharpening automatically.
  • the sharpening means must be as small as possible. As shown in Figures 12, 12a and 13, these means are fixed to the presser foot (29).
  • the principle adopted is as follows two small tongues (42) and (43), on which abrasive pads are fixed (covered with diamond powder for example), are articulated around a common axis (48), which is fixed vertically on the presser foot (29).
  • the tongues (42) and (43) are held in position apart by a small spring (45), the details of which are given in FIG. 12. They are positioned so as to tangent the cutting blade (20), without touching it.
  • the tongues (42) and (43) include an extension (43 ′) having the shape of a vertical tongue.
  • the lower opening of the guide (22) is machined in a flared shape so as to present above each tongue (42) and (43) an inclined plane (46), close to the vertical.
  • sharpening means in addition to their extreme compactness, have the advantage of automatically compensating for the wear of the blade. In addition, there is no need for any specific additional command since sharpening occurs systematically at each blade lift.
