Definitions

  • the invention relates to a machine for varnishing and / or printing sheets according to the preamble of claim 1.
  • a machine of this kind is known.
  • the invention particularly relates to the control of the position of the sheets introduced into such a varnishing and / or printing machine.
  • the function of this positioning control is to ensure the precision required for the application of varnishes and / or printing layers on said sheets with the aim in particular that areas reserved for subsequent welding are not soiled by the coating product.
  • a metallic packaging involves a certain number of operations intended to produce a box body, most often tubular cylindrical, from a sheet metal blank, this box body is materialized by a welding of two joined parallel edges of said blank.
  • this welding process requires that the contact resistances between the two joined edges are constant and perfectly controlled in order to uniformly distribute the heat energy in each volume unit.
  • the varnishing and / or printing station often comprises a transfer roller or "blanket” and a pressure roller cooperating with the transfer roller.
  • the sheets are introduced between these two rollers.
  • the sheets are deposited on a known structure i called "margin table" placed immediately upstream of the two rollers and comprising means for conveying said sheets and means for positioning them relative to the rollers.
  • the sheets are driven by the rollers themselves.
  • the positioning of the sheets on said margin table therefore conditions the precision of the printing and, in particular, the preservation of reserve strips for welding. by known mechanical means, but it must be checked for each sheet. This check is difficult due to several parameters which may change: dimensions and thickness of the sheets, characteristics of the products applied, speed of movement of the sheets on the margin table, etc.
  • Document EP A 0 113 826 describes, in the field of photocopying machines, the use of two sensors to control the correct orientation of the sheets of paper in circulation.
  • the invention aims to allow precise control of the positioning of the sheets as they pass over the margin table.
  • the identification and / or evacuation control signal can be used, depending on the degree of automation sought, to cause the marking of the sheet incorrectly positioned during its passage between the rollers and thus allow its subsequent elimination, or else to control a routing or ejection system performing the automatic sorting of the sheets, for example at the outlet of the varnishing and / or printing machine.
  • the method defined above also applies whenever a precise positioning of any pieces on a transfer means is sought.
  • the pulse generator may be a fixed and / or adjustable frequency generator, it will preferably be a generator controlled by the speed of progression of said flat objects, such as for example an incremental encoder or the like coupled to the 'shaft of one of the above rollers.
  • each pulse is directly representative of an elementary displacement of said flat object and the scrolling speed of the latter can be modified at will without it being necessary to correct the aforementioned predetermined tolerance range constituting the reference with respect to which positioning is or is not considered correct.
  • a varnishing and / or printing machine 11 comprising two rollers with parallel axes of rotation, respectively a transfer roller 12 or "blanket” and a pressure roller 13, rotating in direction reverses from each other to drive a flat object taken from a margin table 14 where the positioning of such objects to be treated, here in this case, sheets 22.
  • the transfer roller 12 receives a varnish or printing products and possibly includes the imprint of an image to be transferred onto the sheet. It is supplied with ink or varnish from a reservoir 18 via a system of application rollers 19.
  • the margin table 14 comprises, for example, conveyor belts and two parallel chains 20 provided with tabs 21 for pushing each sheet 22, rectangular, towards the rollers 12 and 13.
  • the roller 13 comprises a retractable longitudinal stop (not visible on the drawings) projecting from its cylindrical surface, so that the longitudinal positioning of the sheet is ensured when the front transverse edge 22a thereof comes into contact with this stop.
  • a failure of this axial positioning system results in a crossing of the sheet between the rollers, with the printing defects that this implies with respect to the subsequent cutting of said sheet into several blanks.
  • the margin table 14 is provided with a fixed lateral stop 25 opposite which is a movable lateral stop 26 moved by a jack 27 or similar means. This system ensures the transverse positioning of the sheet, relative to the roller. A failure of this transverse positioning system or simply a sheet that does not have the expected width results in a shift of the cutting zones 30 of the sheet defined between the decorations 31 corresponding to each blank.
  • the invention makes it possible to control the correct positioning of a sheet engaged between the rollers and, first of all, the longitudinal positioning with a view to detecting possible "crossings" of this sheet.
  • the margin table 14 for two sensors 35 (for example photoelectric cells or similar components) placed at two fixed reference points and distant from each other.
  • the two reference points are placed on a line strictly parallel to the axis of the roller 12 so that if the sheet 22 is correctly engaged between the rollers, the rear edge 22b of the latter discovers the two sensors 35a, 35b ,at the same time.
  • a pulse generator 40 constituted here by an incremental encoder or the like is coupled to the rotation shaft of the roller 12.
  • the pulses delivered by the generator 40 are counted between the two time intervals separating the change of state of the two sensors 35a, 35b in order to assess the importance of a possible crossing of the sheet and one generates an identification and / or control signal for evacuating the sheet 22 when the number of pulses thus counted is not within a predetermined tolerance range.
  • the two sensors are connected (FIG. 3) to identification and / or evacuation control means capable of generating a usable signal at an output S each time that a sheet 22 has not been correctly printed. or varnished.
  • These means include shaping circuits 36a, 36b connected to receive the signals from the sensors 35a, 35b and delivering, for example, the signals a and b (FIG. 4) applied to two corresponding inputs of a counter 38 which also receives the pulses c of a relatively high frequency, delivered by the pulse generator 40.
  • the count 38 is such that the first falling edge of a pulse a (respectively b) triggers the counting and that the second falling edge of the pulse b (respectively a) stops counting.
  • the input circuits of the counter 38 can be provided, for example, with an exclusive OR "function" receiving the signals a and b.
  • the counting output of counter 38 is connected to display means 60 of the number of pulses counted between the falling edges of pulses a and b and to a digital comparator 41 which also receives a setpoint delivered by a circuit d addressing 42, programmable. An identification and / or evacuation command signal appears at the output S of this comparator if the result of counting n (FIG. 4) is greater than the set value of the addressing circuit 42.
  • the sensors 35g and 35b are placed at such a distance from the rollers 12 and 13 that the counting takes place when the sheet is already largely engaged between said rollers and that an additional variation in positioning is not no more possible.
  • two other lateral sensors 45a, 45b are respectively arranged in the vicinity of the intended location of the longitudinal edges of the sheet 22, that is to say spaced by a distance corresponding to the width of this sheet but to be nevertheless covered at the same time by it. They are connected to comparison means 48. These are, here, symbolized by a single door of the non-OR type and the output of the comparison means is connected to drive said aforementioned identification and / or evacuation control means. . More precisely, according to the nonlimiting example shown, the arrangement is such that the signal delivered by the comparison means 48 is applied to the output S via a validation circuit 49 controlled by the counter 38.
  • the verification good lateral positioning of the sheet (which must result in the fact that the two sensors 45a, 45b are concealed at the same time by said sheet) takes place simultaneously with the counting period.
  • a longitudinal and / or lateral positioning defect results therefore always by the appearance of a signal usable at the output S, to control marking means or means for automatic sheet removal (not shown) located downstream of the machine 11.
  • the sensors 45a, 45b can also be photoelectric sensors or the like. Their positioning can be adjustable, to allow the printing of sheets of different dimensions.
  • the display means 60 connected to the output of said counter 38, makes it possible to monitor the importance and the evolution of the "cross" during a given period of use.
  • the results displayed can be used to adjust the rate of passage of the sheets in the varnishing and / or printing machine 11, with the aim of obtaining a zero or minimum number of rejects.
  • the operating conditions may indeed vary depending on the quality of the batch of sheets being processed, but it has been determined that the processing rate was an important factor in the number of rejects, all other things being equal. This is why, for a batch of mediocre quality sheets, it is necessary to reduce this rate. This is done as a function of the information delivered by the display means 60, either manually, by an operator responsible for monitoring the operation of the machine 11, or automatically if provision is made for processing and control means between an output of the counter 38 and means for actuating this machine 11.
