Definitions

  • the present invention relates to a device for driving strip, plate or wire materials.
  • a drive motor is connected to one of the rollers, which transmits its movement to the other roller through a set of two pinions wedged on their axes.
  • One of the rollers is movable transversely, that is to say in a direction substantially perpendicular to that of the advancement of the material, in order to be able to be moved away from the other roller to allow the engagement of the material or to cut out the material when it is taken up by the machine tools which ensure its positioning and handling during its work.
  • the distance between the rollers is determined as a function of the thickness of the material treated and of the desired clamping pressure, itself determined by the nature of the material and / or its surface condition.
  • the American patent does not provide suitable means such as jacks for pressing the movable roller on the material engaged between the two rollers, nor means for sufficiently spreading the rolls from each other when engaging the material. This results in significant inaccuracy in the advancement of the material and during the peeling operation.
  • the German patent provides a chassis pivoting around a shaft whose height is adjustable, a jack for spreading or bringing the rollers closer by exerting pressure on them, and a cam capable of pressing on the chassis to perform the cutting of the material.
  • This device has the drawback of being complex to produce and imprecise in adjusting the spacing of the rollers and during the stripping operation due to the forces which the chassis and its pivot shaft undergo.
  • the present invention seeks to remedy these drawbacks by providing a device which is simple to produce and which allows perfect precision in adjusting the spacing of the rollers.
  • the device according to the invention which is of the type comprising two parallel rollers intended to press the material engaged between them and driven in rotation in opposite directions to one another, one of the rollers being transversely movable and carried by a frame forming a yoke articulated on a fixed axis parallel to that of the rollers, comprises in combination at least one pneumatic double-acting cylinder connected to the chassis, intended, by pivoting the chassis, to allow the pressing of the rollers on the material or their spacing, and an adjustable stop, arranged on the trajectory of the chassis to which it is connected at a point located near the point or points of action of the jack or jacks on it, the stop being intended to allow the adjustment of the spacing of the rollers and limiting the stroke of the chassis in the pressing direction, this same adjustable stop being further shaped to be suitable, in cooperation with appropriate means opiate, to counteract the action of the actuator (s) so as to perform the material removal.
  • the adjustable stop serves both when adjusting the spacing of the rollers and during the peeling operation.
  • the combination of the action of the jack (s) and the adjustable stop allows on the one hand, after adjusting the spacing of the rollers and by exerting pressure on the movable roller, to maintain this spacing perfectly constant for that the advancement of the material takes place with precision, and on the other hand, that the rollers exert the desired clamping pressure as a function of the material treated.
  • the spacing of the rollers is done in a perfectly precise manner during the de-punching operation.
  • the device is simple to make and very precise, the chassis not being subjected to significant torsional forces.
  • the cylinder or cylinders are controlled by an electronic encoder mounted on the end of the machine crankshaft, so that the pressing of the rollers is carried out in a coordinated manner with the work of the material by the machine tools.
  • the adjustable stop is constituted by a cylinder comprising a chamber in which is housed a spring on which a piston acts, the rod of which is articulated, by its free end, to the cross member of the aforementioned chassis by an axis engaged in an oriented light in the axis of the piston, the end of the cylinder having, at its end opposite to that traversed by the piston rod, a bore engaged on an eccentric carried by an axis, the angular position of which is adjustable.
  • the adjustable stop is constituted by a stirrup articulated on the chassis and carrying a screw bearing on a lever pivotally mounted, by one of its ends, around an axis fixed to the frame of the machine, its other end being in contact, directly or indirectly, with a crown-cam linked in rotation to a shaft driven by the crankshaft of the machine.
  • the oscillating pivoting movement transmitted to the lever by the cam-crown is transmitted to the chassis via the screw and the caliper, which causes the material to be tacked.
  • the actuation of the screw changes the position of the stirrup relative to the lever and therefore that of the chassis, so that the spacing of the rollers can be adjusted according to the thickness of the material to be advanced.
  • the spacing of the rollers, in order to be able to engage the material between them, is achieved simply by injecting pressurized air into the lower chamber of the jacks.
  • This variant has the advantage, compared to the first embodiment described, of avoiding the use of an electronic device coordinating the action of the jacks during the transit of the material, as well as a limitation of the rate due to the inertia of the cylinders.
  • This device comprises two rollers 1 and 2 intended to press, for its advancement, a material 3, in the form of a strip, engaged between them.
  • the rollers 1 and 2 are rotated in opposite directions to one another in order to advance the material, in the direction of the arrow, by friction.
  • the drive of the roller 2 is obtained from a hydraulic motor 4, by means of two wheels 4a and 5 and a toothed belt 6; that of roller 1 is obtained, from roller 2, by means of a set of four pinions 8, 10, 9, 7 shown in phantom in Figures 1.3 and 4.
  • the pinions 7 and 8 are respectively wedged on the shafts 11 and 12 of the rollers 1 and 2.
  • the pinion 9 is carried freely by an axis 13.
  • the intermediate pinion 10 carried by an axis integral with the frame, meshes with the pinion 9 and the pinion 8.
  • the device further comprises rollers 14 for guiding the material 3, each of which is mounted on an axis 15 engaged in a transverse slide 16 making it possible to move it and, consequently, to adjust their spacing as a function of the width of the material 3, each axis 15 being able to be immobilized in the desired position thanks to a locking member 17.
  • roller 1 is carried by a frame 18 forming a yoke, mounted pivoting about the axis 13 and with which are associated two double-acting pneumatic cylinders 19 whose piston rods are articulated to the frame 18 and whose bodies are articulated to the machine frame.
  • This device comprises an adjustable stop 20 constituted by a cylinder 21 comprising a chamber 22 in which is housed a spring 23 compressed between the bottom of the chamber 22 and a piston 24 whose rod 24a is articulated, by its free end, to the cross member of the chassis 18 by an axis 25 engaged in a slot 26 oriented in the axis of the piston 24.
  • the upper part of the cylinder 21 has a bore 27 engaged on an eccentric 28 integral with an axis 29 supported by the frame of the machine.
  • FIG. 2 shows more particularly that the end of the axis 29 opposite to that carrying the eccentric 28 passes through, in its center, a disc 30 fixed to the frame as well as an operating part 31 which is linked to it in rotation while by being axially movable relative to it.
  • the part 31 carries a lug 32 capable of engaging in one of the opposite holes formed in the disc 30.
  • the part 31 contains a spring 33 compressed between its bottom and a stop 34 integral with the end considered of the axis 29 in order to keep it tight against the disc 30.
  • the device according to the invention operates as described below:
  • the jacks 19 act on the chassis 18 so that the material 3 is pressed between the rollers 1 and 2 which are themselves driven in rotation by the motor 4.
  • the air is injected into the lower chamber of the jacks 19 at a pressure sufficient to pivot the chassis 18, but not sufficient to cause the piston 24 to compress the spring 23, that is to say, in practice, a pressure of approximately 2 bars, the chassis 18 only pivots by the stroke allowed by the oblong opening 26.
  • the part 31 can be moved away from the disc 30 in order to bring the pin 32 into the opposite hole made in the disc 30, to the desired angular position, in order to orient, via the axis 29, the eccentric 28 so that it displaces the whole of the adjustable stop as a function of the thickness of the material 3 to be brought.
  • FIG. 5 represents an alternative embodiment of the device in which the mechanism allowing the spacing of the rollers is different.
  • the device includes elements identical to those described above, which are found with the same references.
  • the adjustable stop 32 is constituted by a stirrup 36, articulated to the chassis 18, and carrying a screw 37.
  • the end of the screw 37 is supported on a lever 38 which comprises, for this purpose, a flat 38a .
  • the lever 38 is pivotally mounted, by one of its ends, about an axis 39 fixed to the frame of the machine, its other end carrying a cam roller 40 in contact with a cam-crown 41 linked in rotation to a shaft 42 driven by the crankshaft of the machine.
  • the cam-crown 41 lifts the lever 38 which transmits its movement to the chassis 18, thus making it possible to cut the material 3.
  • the actuation of the screw 37 modifies the position of the stirrup 36 relative to the lever 38 and therefore, that of the chassis 18, so that the spacing of the rollers 1 and 2 can be adjusted in this way as a function of the thickness of the material 3.
  • the spacing of the rollers l and 2, so that the material 3 can be engaged between them, is achieved by simply injecting air into the lower chamber of the jacks 19, which causes the chassis 18 and the stirrup 36 hinged to pivot.
