Definitions

  • the present invention relates to the marking of products on parade, by ink jets. More particularly, the invention relates to a method and a device for marking in the parade by ink jets of a surface not parallel to the plane of travel of the products, in particular of a cylindrical surface such as the rolls of paper reels.
  • Ink jet marking consists of spraying ink in given sequences from several aligned nozzles to form ink dots which define printing characters.
  • Marking of paper reels with ink jets is known. It is carried out on the edge of the reels, in a straight line, by scrolling the reel in front of the marking device, or by moving it in front of it, the running plane being always parallel to the surface to be marked.
  • the marking can also be carried out on the cylindrical or rolled part of the reel. It is then always carried out at a station where the coil, stationary in translation, can be driven in a rotational movement on itself (FR-A-2 398 611). It then requires significant means to rotate the coil on itself, and also a period of immobilization in translation of the coil at least equal to the duration of the marking.
  • the invention provides a method and a device for marking products in parade by ink jets on at least one surface of said products, surface arranged not parallel to the plane of travel thereof, particularly simple method and device, easy to to implement and which do not require any immobilization of the products to be marked.
  • the invention applies to the marking of many products of different shapes, having surfaces to be marked flat or curvilinear, for example products of triangular, curvilinear, cylindrical shape, etc.
  • the product to be marked is moved in a rectilinear manner, opposite at least one marking head, the surface or surfaces to be marked being arranged not parallel to the plane of travel of the product, and the product (s) is marked running surfaces, elastically holding the marking head (s) perpendicular to the surface (s) to be marked, at a constant distance therefrom, throughout the marking operation.
  • the reel can be placed on the straight conveyor, lying on the roll, its axis being perpendicular to the plane of the conveyor.
  • the marking head is arranged above the conveyor and the marking at the parade is carried out from above the roll.
  • the reel is placed upright on the edge, the marking head or heads then being placed on the side of the conveyor and the marking in the process is carried out from the side. It is thus advantageously possible to successively or simultaneously mark two opposite sides of the roll (or two lateral faces of a product of triangular shape for example).
  • the inscription is substantially symmetrical with respect to this axial tilting plane.
  • the invention also relates to a device for marking products in a parade, marking by ink jets on at least one surface of said products, arranged not parallel to the plane of travel thereof.
  • the device according to the invention comprises a rectilinear conveyor for the products to be marked, at least one marking head disposed above the conveyor or on the side, this head being articulated around an axis parallel to the plane of travel of the products , at the end of a system with elastic movement and return, acting essentially perpendicular to the axis of the conveyor such as a spring or a jack, which ensures the maintenance of the head in the marking position during the whole operation, a guidance system determining the correct orientation of the marking head at all times.
  • the guide system is a sensor which surrounds the marking head and which comprises rods terminated by rolling balls serving as touch points on the surface to be marked, in particular the roll of the spool to follow that -this without rubbing and possibly damaging the coil.
  • two marking heads when the reel is placed on the edge, two marking heads can be associated, each of them operating simultaneously or separately on opposite sides of the roll relative to the axial plane of the reel, parallel to the movement of this one.
  • the device comprises a system giving the marking head an upstream orientation, that is to say towards the center of the reel, when approaching the latter. It is for example a pneumatic system with adjustable stroke.
  • a reel of paper standing on its edge is driven by a straight conveyor not shown in a forward movement according to arrow F.
  • the marking head 2 is shown in three successive marking positions.
  • Position A corresponds to the start of the marking.
  • the marking head articulated around an axis 3 parallel to that of the coil, that is to say parallel to the plane of travel of the latter (the plane of travel passing through the axis of the coil), is oriented towards the center thereof, upstream, by a ball feeler 4 which follows the curvature of the coil, and which is integral with the head.
  • the axis 3 is mounted at the end of a system with elastic travel and return 5 acting perpendicular to the axis of the conveyor. This system keeps the probe applied against the roll 6 of the coil and therefore the head close to the latter, thanks to the radial component R of the force which it exerts on the axis 3.
  • the nozzles 7 by which the ink for printing is projected are arranged at a suitable and constant distance from the spool.
  • the reel moves the probe and the marking head away from the axis of the conveyor and the system with elastic travel and return retracts perpendicularly according to the arrow F l .
  • Position B generally corresponds to the middle position for marking. In this position, the head is located in the tilting plane b. The elastic system is retracted to the maximum.
  • Position C corresponds to the end of the marking.
  • the head is still oriented towards the center of the coil by the probe, but downstream this time.
  • the elastic system is in its exit stroke along F z .
  • FIG. 2 represents a variant implementation of the invention, but which applies the same principle of marking.
  • the axis 8 around which the marking head 9 is articulated is mounted at the end of an oscillating arm 10, according to the arrows F 3 and F 4 around an axis 11 parallel to that of the coil.
  • the oscillating arm 10 is disposed substantially along a parallel to the axis of the conveyor when the coil is arranged on the wafer.
  • This variant uses the same means for orienting the head, that is to say a ball probe 2 kept applied against the roll of the reel.
  • FIG. 3 shows in the marking position an embodiment of the device according to the invention for the implementation of marking on the run, the paper reel 1 being placed upright on the edge, on a rectilinear conveyor.
  • the marking head 20 is mounted in a structure 21 carried by a stirrup 22 pivoting about a vertical axis 23 carried by a flange 24.
  • the marking head is arranged in a plane perpendicular to the axis of the coil.
  • the structure 21 comprises a metal plate 25 on which are fixed four rods 26 arranged around the marking head at its four corners. Each of these rods carries at its end a handling ball 27, the position of which is adjustable using a screw-nut system 28. The position of the balls is adjusted so that the contact of these balls with the roller 6 of the coil corresponds to a determined distance from the marking nozzles 29 with this roll.
  • the flange 24 is mounted on a plate 30 carrying a second bracket 31 crossed by a horizontal axis 32 on which is articulated the rod 33 of an air spring 34 whose body is mounted in a hollow rod 35 and on an axis 36 crossing this rod.
  • the connection of the rod 33 with the plate 30 can be done by a simple fastener.
  • the rod 35 is adjustable according to the double arrow Y transversely relative to the displacement of the coil, by being slidably mounted in two horizontal bearings 37 carried by a plate 38 mounted at the end of another rod secured to a frame not shown.
  • the sliding rod 35 carries at its end 40 two horizontal bearings 41 arranged transversely to the displacement of the coil, in which slide two guide rods 42 whose ends 43 are fixed on the plate 30.
  • the advance of the guide rods is limited by two stops 44.
  • the two guide rods 42 frame the rod 33 of the air spring 34. The length of these rods and the stroke of the air spring rod are easily determined according to the length desired for the marking and the diameter of the coils.
  • the plate 30 also carries a cover 45 surrounding the body of an air spring 46 mounted on an axis 47 passing through said cover 45.
  • the rod 48 of this spring is fixed to another axis 49 carried by a bearing 50, mounted on the part downstream of the plate 25 of the structure 21, so that the marking head is oriented towards the coil when it approaches it.
  • a fifth adjustable rod 52 carries a handling ball 53 adjustable using a screw-nut system 54, this ball being applied to the roll of the coil by the action of the pneumatic spring 46.
  • the four rods 26 and the rod 52, fitted with balls, constitute a sensor guide device which gives the correct orientation to the marking head at all times.
  • the device works as follows:
  • the position of the marking head relative to the conveyor and to the coils to be marked is determined by adjusting the rod 35 which is then locked, for example using screws.
  • the marking head Under the action of the two pneumatic springs which are at the end of the stroke, the marking head is oriented according to a determined angle of attack for the rectilinear approach of the coil which is placed upright on the edge on the conveyor.
  • the length of the rods 26 and 52 are also adjusted.
  • the reel arriving at the marking station the ball 53 comes first into contact with the wheel 6, the marking head pivots around the axis 23 until the balls 27 come into contact with the wheel.
  • the head is then correctly oriented, according to a radius of the coil.
  • the actual marking operation begins.
  • the ink jet marking is programmed in a known manner using a microprocessor.
  • the different nozzles are supplied with ink, by supply pipes, not shown, in a sequenced manner.
  • the marking is carried out on the roll of the reel during the parade, when the latter passes in front of the marking head which marries at all times the curvature of the reel thanks to the handling balls applied against the roll by the pneumatic springs.
  • the marking head moves away more and more from the axis of the conveyor.
  • the guide rods 42 slide inside the two bearings 41 and the rods of the two air springs retract.
  • the marking head by changing the inclination, continues its course along the roll of the coil under the action of the pneumatic springs and the feeler.
  • the spool escapes from the marking device and the head returns to its original inclination, that is to say an orientation upstream and it is then ready for the marking of the next spool .
